Description

  The present invention relates to an electronic control device including a circuit board and an electronic component mounted on the circuit board.

  Conventionally, as an example of an electronic control device, for example, one disclosed in Patent Document 1 is known.

JP 2014-180949 A

  By the way, in general, an electronic control device often has electronic components mounted on the surface of a circuit board. The electronic component is mounted on the circuit board with its own terminal inserted in a through hole provided on the circuit board, or its own terminal is connected to a land provided on the surface of the circuit board It is mounted on the circuit board. In the electronic component, the terminal and the circuit board are electrically and mechanically connected via a conductive connecting member.

  However, the electronic control device may be displaced when an external force is applied to the electronic component. In the electronic control device, when the displacement of the electronic component occurs, the durability of the terminal or the connection member that is a connection portion between the electronic component and the circuit board may be reduced.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic control device capable of improving durability at a connection portion between an electronic component and a circuit board.

In order to achieve the above object, the present invention provides:
A first circuit board (30a, 30e, 30g);
It has terminals (30c1, 30f1, 30h1), and the terminals and the first circuit board are electrically and mechanically connected via the conductive connection member (60), and mounted on the mounting surface side of the first circuit board. An electronic control device (20, 20a, 20b) comprising the electronic components (30c, 30f, 30h),
The first circuit board is a part into which a part of the electronic component is inserted, and the first hole portion (30a1, 30e1, 30g1) that suppresses the displacement of the electronic component by inserting a part of the electronic component. Is provided,
Furthermore, a pressing member (30b, 30d, 31a, 35) for pressing the electronic component against the first circuit board in a direction perpendicular to the mounting surface is provided.

  In the present invention, the first hole is provided in the first circuit board. According to the present invention, the displacement of the electronic component can be suppressed by inserting a part of the electronic component into the first hole. The present invention also includes a pressing member that presses the electronic component disposed in the first hole of the first circuit board against the first circuit board. In other words, in the present invention, the first hole portion and the pressing member suppress the displacement of the electronic component. Therefore, according to the present invention, even when an external force is applied to the electronic component, the electronic component is not easily displaced. As described above, according to the present invention, since the electronic component is not easily displaced, the durability of the terminal and the connection member, which are the connection portion between the electronic component and the first circuit board, can be improved. Furthermore, according to the present invention, since a part of the electronic component is inserted into the first hole, the thickness can be reduced accordingly.

Further features of the invention include
A bag-shaped housing (31, 31a) containing the first circuit board and the electronic component;
And a sealing resin (70) that is provided in the housing, covers the first circuit board and the electronic component, and fixes the electronic component to the first circuit board.

  Thus, according to the present invention, the sealing resin that covers the first circuit board and the electronic component is provided in the housing. It is conceivable that this sealing resin flows into the casing when it is provided in the casing. In this case, since the sealing resin that flows into the housing hits the electronic component, an external force is applied by the sealing resin. However, according to the present invention, as described above, since the first hole and the pressing member suppress the displacement of the electronic component, the electronic component is not easily displaced even when the sealing resin is poured into the housing. . Therefore, this invention can suppress sealing with sealing resin in the state which the electronic component shifted.

  For example, when the electronic component is displaced, stress may be applied to the terminal and the connection member. Therefore, when the electronic component is sealed with the sealing resin while being displaced, the electronic component is fixed to the first circuit board in a state where stress is applied to the terminal and the connecting member. For this reason, a terminal and a connection member are easy to bend a terminal or to have a crack in a connection member. However, according to the present invention, since the electronic component can be prevented from being fixed in a misaligned state, the durability of the terminal and the connection member can be improved even when a sealing resin is provided.

  First, based on FIG.1 and FIG.2, an example of the mounting environment of the electronic control apparatus 20 of this embodiment is demonstrated. As shown in FIG. 1, the vehicle 10 has a hood 12 in front of the front windshield 11. The bonnet 12 is also referred to as a hood. A front fender 13 is attached to both sides of the bonnet 12 in the left-right direction of the vehicle in order to protect the occupant from unillustrated tires and splashes of stones, mud, water and the like. Further, headlights 14 are provided in front of the vehicle 10 on both the left and right sides. A front grille 15 is provided between the headlights 14 for taking in air from the outside.

  As shown in FIG. 2, an engine 18, a vehicle auxiliary machine, and the like are arranged in an engine compartment 17 below the hood 12 that is separated from a passenger compartment (cabin) in which an occupant is boarded by a partition wall 16. The engine compartment 17 is also referred to as an engine room. It can be said that the engine compartment 17 is a compartment and the bonnet 12 is a lid on the compartment. The engine compartment 17 is defined by a front fender 13, a front grill 15, a partition wall 16, and the like.

  In addition to the engine 18, the engine compartment 17 includes a battery 19, an electronic control unit 20, a relay box 21, and the like. The electronic control unit 20 is configured as an engine ECU (Electric Control Unit). The battery 19 can also be said to be a box-shaped member. The electronic control unit 20 executes calculation of a target torque that the engine 18 should output. Further, the electronic control unit 20 controls the opening degree of the throttle valve, the fuel injection amount, the ignition timing, and the like through the wire harness 22 in order to generate the target torque required by the engine 18.

  The relay box 21 includes a large number of relays and fuses in order to distribute the power of the battery 19 to the electrical components in the vehicle. The relay box 21 is supplied with electric power to the electronic control device 20 through a part of the wire harness 23 or a control signal is input from the electronic control device 20. The electronic control unit 20 controls the supply of electric power to the electrical components mounted on the vehicle 10 by this control signal. The remainder of the wire harness 23 is connected to various body-type ECUs, meters, various switches, and the like (not shown) through through holes 16 a provided in the partition wall 16. As a result, signals can be exchanged between the electronic control unit 20 and the various ECUs and controlled objects of the body. In order to distinguish the wire harness 22 and the wire harness 23 from each other, the wire harness 22 can be referred to as an engine-side harness, and the wire harness 23 can be referred to as a relay-side harness.

  Next, the battery 19 and the electronic control device 20 arranged next to the battery 19 will be described with reference to FIGS.

  The battery 19 is charged and discharged in order to control various electric devices and electronic devices. As shown in FIGS. 3 and 4, the battery 19 has a substantially rectangular parallelepiped shape, and as an outer surface, an upper surface 19 a on which terminals and the like (not shown) are formed, a long side surface 19 b and a short side surface 19 c which are side surfaces, And a bottom surface (not shown) opposite to the top surface 19a. The long side surface 19b is a side surface connected to the long side of the upper surface 19a having a substantially rectangular shape, and the short side surface 19c is a side surface connected to the short side of the upper surface 19a. The pair of long side surfaces 19b and the pair of short side surfaces 19c are both substantially flat surfaces, that is, flat portions 19d. The battery 19 is disposed on a bottom plate portion 55 that constitutes a tray portion 54 of the bracket 33 described later.

  The battery 19 is fixed to the tray portion 54 and eventually the vehicle 10. A clamp member 24 that clamps the battery 19 is disposed on the upper surface 19 a of the battery 19. The clamp member 24 is disposed so as to straddle the upper surface 19a along the short side direction in the vicinity of the center of the long side. As shown in FIGS. 3 and 5, both ends of the clamp member 24 are extended outward from the upper surface 19 a. J-shaped hook members 25 are connected to both ends of the clamp member 24. In the hook member 25, the lower end portion opposite to the connection end with the clamp member 24 is bent in a J-shape. Of the horizontal plate portions 56 and 57 constituting the tray portion 54 described above, a latching portion 59 is formed on the horizontal plate portion 57 disposed opposite to the long side surface 19b of the battery 19, and a hook is attached to the latching portion 59. The lower end portion of the member 25 is latched. As described above, the battery 19 is sandwiched between the bottom plate portion 55 and the clamp member 24.

  As shown in FIG. 12 and the like, the electronic control unit 20 includes a first circuit board 30a, a second circuit board 30b, a housing 31, and a connector 32. Electronic components are mounted on the first circuit board 30a and the second circuit board 30b. The electronic component mounted on the first circuit board 30a includes a circuit element 30c. That is, it can be said that the electronic control unit 20 includes the circuit element 30c in addition to the above-described components 30a, 30b, 31, and 32. Further, in this embodiment, the electronic control device 20 in which the potting material 70 is filled in the casing 31 is employed. In the following, when it is not necessary to distinguish the first circuit board 30a and the second circuit board 30b, they are also referred to as circuit boards 30a and 30b.

  The circuit boards 30a and 30b are obtained by forming a conductor pattern or the like on an insulating base material. As the circuit boards 30a and 30b, a printed board or a ceramic board can be adopted. Further, the first circuit board 30a and the second circuit board 30b are, for example, flat-plate-shaped boards.

  As shown in FIGS. 12, 13, and 14, the first circuit board 30a has a positioning hole 30a1 and a through hole 30a2. In FIG. 13, the casing 31, the potting material 70, and the like are omitted.

  The positioning hole 30a1 corresponds to the first hole in the claims. The positioning hole 30a1 is a hole penetrating in the thickness direction of the insulating substrate, and is a hole for defining the position of the circuit element 30c described later. In other words, the positioning hole 30a1 is a hole for suppressing the displacement of the circuit element 30c mounted on the first circuit board 30a. Further, the positioning hole 30a1 is a part into which a part of the circuit element 30c is inserted (embedded) as shown in FIGS.

  Further, the positioning hole 30a1 suppresses the positional deviation of the circuit element 30c by inserting (embedding) a part of the circuit element 30c. For this reason, as shown in FIGS. 14 and 15, the positioning hole 30a1 is a hole whose width is narrower than the diameter of the body portion of the circuit element 30c. In addition, the length of the positioning hole 30a1 is equivalent to the length of the trunk | drum part in the circuit element 30c, as shown in FIG.

  The through hole 30a2 is a hole that penetrates in the thickness direction of the insulating base material, and is a hole into which the element side terminal 30c1 that is a terminal of the circuit element 30c is inserted. In the through hole 30a2, a conductive member such as copper plating is formed on the surface of the hole penetrating in the thickness direction of the insulating base material. The through hole 30a2 is electrically and mechanically connected to the element side terminal 30c1 inserted therein by the solder 60. The element-side terminal 30c1 and the solder 60 can be said to be a connection portion between the first circuit board 30a and the circuit element 30c.

  In the present embodiment, the element side terminal 30c1 is inserted into the through hole 30a2, and the element side terminal 30c1 and the first circuit board 30a are electrically and mechanically connected. However, the present invention is not limited to this. As will be described later, the present invention can also be applied to the circuit element 30h having a surface mounting structure.

  On the other hand, the second circuit board 30b is disposed opposite to the mounting surface of the first circuit board 30a. The second circuit board 30b corresponds to a pressing member in the claims. The second circuit board 30b is in partial contact with the circuit element 30c. Then, the second circuit board 30b presses the circuit element 30c against the first circuit board 30a in the direction perpendicular to the mounting surface. Further, although not shown, the second circuit board 30b is mounted with an electronic component different from the circuit element 30c. As will be described later, the electronic control unit 20 can fix the circuit element 30c to the first circuit board 30a with the potting material 70. Therefore, the second circuit board 30b may be one that presses the circuit element 30c against the first circuit board 30a at least when the potting material 70 is injected into the housing 31. That is, the second circuit board 30b can be said to be a temporary holding member for preventing the circuit element 30c from being displaced when the potting material 70 is injected into the housing 31.

  As shown in FIG. 12 and the like, the first circuit board 30 a and the second circuit board 30 b are accommodated in the casing 31 and fixed to the casing 31 by a potting material 70. The first circuit board 30a and the second circuit board 30b may be fixed to the casing 31 by a fixing means (not shown) in addition to the potting material 70. A connector 32 is also mounted on the first circuit board 30a and the second circuit board 30b. For example, the first circuit board 30a and the second circuit board 30b can be held at a distance from each other by being fixed to one connector 32. The connector 32 will be described later.

  The circuit element 30c corresponds to an electronic component in the claims, and an aluminum electrolytic capacitor is adopted as an example. The circuit element 30c has an element-side terminal 30c1, and the element-side terminal 30c1 and the first circuit board 30a are electrically and mechanically connected via the solder 60, and mounted on the mounting surface side of the first circuit board 30a. Has been. The solder 60 corresponds to the connecting member in the claims. In the present invention, a conductive adhesive or the like can be used instead of the solder 60.

  For example, as illustrated in FIGS. 12 and 13, the circuit element 30 c includes a cylindrical body portion and two element-side terminals 30 c 1 protruding from the body portion. That is, the body part of the circuit element 30c has a shape including a cylindrical part and circular wall parts formed at both ends of the cylindrical part. The circuit element 30c is formed such that each element-side terminal 30c1 protrudes from one of the two circular wall portions. Each element-side terminal 30c1 includes, for example, a protruding portion protruding from a circular wall portion and a bent portion bent from the tip of the protruding portion, and can be said to be L-shaped. In the present embodiment, the element-side terminal 30c1 including a flat circular wall portion, a protruding portion provided perpendicular to the circular wall portion, and a bent portion provided in parallel to the circular wall portion at the tip of the protruding portion is employed. doing. Thus, in this embodiment, a THD (Through Hole Device) aluminum electrolytic capacitor is employed as the circuit element 30c.

  The circuit element 30c is disposed on the first circuit board 30a so that the cylindrical portion is parallel to the mounting surface and the circular wall portion is perpendicular to the mounting surface. The circuit element 30c is mounted on the first circuit board 30a in a state where the bent portion is inserted into the through hole 30a2 of the first circuit board 30a. The circuit element 30c is mounted on the first circuit board 30a so that its own longitudinal direction is parallel to the mounting surface and its short direction is perpendicular to the mounting surface. You can also say.

  Further, only part of the circuit element 30c of FIGS. 12, 13, and 15 itself is disposed in the positioning hole 30a1. More specifically, as shown in FIGS. 12 and 13, in the circuit element 30c, it can be said that only a part of the body portion in the height direction and the whole body portion in the length direction are disposed in the positioning hole 30a1. Further, as described above, since the circuit element 30c is pressed from the second circuit board 30b to the first circuit board 30a, the casing is held between the first circuit board 30a and the second circuit board 30b. It can be said that it is accommodated in 31.

  The electronic control device 20 can suppress the circuit element 30c from being displaced in the lateral direction (Y direction) because the circuit element 30c is disposed in the positioning hole 30a1. Further, in the electronic control unit 20, since the circuit element 30c is disposed in the positioning hole 30a1, and the element side terminal 30c1 is inserted into the through hole 30a2 and fixed by the solder 60, the circuit element 30c is in the vertical direction (Z direction). ) Can be suppressed. Furthermore, since the circuit element 30c is pressed against the first circuit board 30a from the second circuit board 30b, the electronic control unit 20 can suppress the circuit element 30c from being displaced in the height direction (X direction). As described above, the electronic control unit 20 can suppress the displacement of the circuit element 30c in the three directions of the horizontal direction, the vertical direction, and the height direction.

  The casing 31 is formed using a metal material. As a result, the housing 31 functions to dissipate heat generated by the circuit boards 30 a and 30 b to the outside of the housing 31. As shown in FIG. 12, the housing 31 has a bag shape, and has a bottom 40 on one end side in the Z direction that is the depth direction of the housing 31, and an opening 41 on the other end opposite to the bottom 40. have. The casing 31 has a side wall portion 42 that is connected to the bottom portion 40 and forms a space for accommodating the circuit boards 30a, 30b and the like together with the bottom portion 40. That is, the side wall part 42 is provided in an annular shape. In addition, since the bottom part 40 forms a part of wall part of the housing | casing 31 with the side wall part 42, it can also be called the bottom wall part 40. FIG.

  As described above, the potting material 70 is provided in the housing 31. The potting material 70 corresponds to the sealing resin in the claims. The potting material 70 covers the first circuit board 30a and the circuit element 30c, and fixes the circuit element 30c to the first circuit board 30a. Further, the potting material 70 covers the second circuit board 30b, and fixes the second circuit board 30b to the first circuit board 30a and the circuit element 30c. Thus, it can be said that the potting material 70 integrally seals the inside of the housing 31 and fixes the components arranged in the housing 31.

  The casing 31 having such a bag shape can be configured by a single member or can be configured by assembling a plurality of members. In this embodiment, the housing | casing 31 is comprised with the single member by employ | adopting the impact processing method using a punch. When the impact processing method is employed, the length in the X direction, that is, the thickness of the housing 31 can be reduced as compared with the assembly of a single member or a plurality of members using the aluminum die casting method.

  As shown in FIGS. 9, 10, 11, and 12, the housing 31 has, as its outer surface, a bottom surface 43 a that is an outer surface of the bottom portion 40 and a facing surface 43 b that is disposed to face the flat portion 19 d of the battery 19. And a back surface 43c opposite to the facing surface 43b, and a pair of connecting surfaces 43d that connect both ends of the facing surface 43b and the back surface 43c in the Y direction. The pair of connecting surfaces 43d is at least part of the Z direction and is inclined to the predetermined range in the X direction so that the distance between the pair of connecting surfaces 43d in the Y direction becomes narrower as the back surface 43c is approached. Respectively. It can also be said that the pair of inclined surface portions 43e are inclined so that the interval between the pair of inclined surface portions 43e gradually decreases from the opposing surface 43b to the back surface 43c. The pair of slope portions 43e are provided to face each other. The interval between the pair of connecting surfaces 43d is a distance in the Y direction from one connecting surface 43d to the other connecting surface 43d.

  In the present embodiment, the opposing surface 43b and the back surface 43c are substantially flat surfaces. And the connection surface 43d becomes the slope part 43e except the bending part which is a connection part with the opposing surface 43b and the back surface 43c. That is, almost the entire connection surface 43d is a slope portion 43e. The angle formed by the connecting surface 43d and the opposing surface 43b is an acute angle, and the angle formed by the connecting surface 43d and the back surface 43c is an obtuse angle. For this reason, as shown in FIG. 10, the housing 31 has a substantially trapezoidal shape when viewed from the Z direction. Therefore, the back surface 43c is located between the pair of connecting surfaces 43d in the Y direction. Further, as shown in FIG. 9, a screw hole 44 having a predetermined depth that opens to the bottom surface 43a is formed in the bottom portion 40.

  As shown in FIGS. 3 and 4, the casing 31 configured in this manner is disposed next to (beside) one short side surface 19 c of the battery 19. More specifically, the housing 31 has a facing surface 43b opposed to the short side surface 19c. The housing 31 is disposed beside the short side surface 19c (plane portion 19d) so that the opening 41 is located above the bottom portion 40. That is, the connector 32 is disposed so as to be above the bottom portion 40. Note that the Z direction substantially coincides with the vertical direction of the vehicle 10. The upper side is the upper side of the vehicle.

  The connector 32 is mounted on the first circuit board 30a and the second circuit board 30b, and electrically relays the first circuit board 30a and the second circuit board 30b and an external device. As shown in FIG. 9 and the like, a part of the connector 32 is accommodated in the housing 31 and the remaining part is exposed from the housing 31 to the outside. The connector 32 is fitted with a connector (female connector) on the external device side, and the circuit boards 30a, 30b and the like are electrically connected to the wire harnesses 22, 23 via the connector 32 and the female connector. For example, in the electronic control device 20, the circuit boards 30 a and 30 b and the engine 18 are electrically connected via the connector 32, the female connector, and the wire harness 22. In the electronic control device 20, the circuit boards 30 a and 30 b and the relay box 21 are electrically connected via the connector 32, the female connector, and the wire harness 23.

  As shown in FIG. 9, FIG. 11, FIG. 16, etc., the connector 32 is formed by using a housing 32a formed of an electrically insulating material such as a resin and a conductive material, and is held by the housing 32a. A plurality of first terminals 32b and a plurality of second terminals 32c are provided. For example, the plurality of first terminals 32b are arranged in the Y direction with respect to the housing 32a and are arranged in multiple stages in the X direction. The same applies to the plurality of second terminals 32c. The number of stages is not particularly limited. The first terminal 32b is electrically and mechanically connected to the first circuit board 30a. On the other hand, the second terminal 32c is electrically and mechanically connected to the second circuit board 30b.

  The connector 32 is disposed at and around the opening 41 of the housing 31 and closes the opening 41. The housing 32 a and the housing 31 are fitted around the opening 41. Further, a waterproof sealing material (not shown) is disposed between the housing 32a and the peripheral portion of the opening portion 41 in the side wall portion. Thereby, as for the electronic control apparatus 20, the internal space of the housing | casing 31 is waterproofing space. In FIG. 12, the first terminal 32b is inserted and mounted on the first circuit board 30a, and the second terminal 32c is inserted and mounted on the second circuit board 30b, but a surface mounting structure is adopted. You can also.

  As shown in FIGS. 3, 7, 9, and 11, the housing 32a of the connector 32 has three ports (in other words, fitting ports). The connector 32 is an engine block in which a part of the three ports is provided for connection to the wire harness 22 for driving the engine 18. The connector 32 is a body block whose remaining ports are used for connection to the relay box 21 and the wire harness 23 corresponding to the body ECU. In the arrangement shown in FIG. 2, the wiring harnesses 22, 23 are arranged so that the engine block is closer to the engine 18 and the body block is closer to the relay box 21 and the through hole 16 a in the arrangement shown in FIG. 2. Considering this, the arrangement of each block is determined. Note that the number of ports of the connector 32 is not particularly limited.

  Further, as shown in FIGS. 6, 11, and 16, the housing 32 a is provided with an inlet 32 a 1 for injecting the potting material 70 into the housing 31. That is, the housing 32a is provided with an injection port 32a1 penetrating in its thickness direction (Z direction). In the electronic control device 20, the potting material 70 is injected into the housing 31 from the injection port 32 a 1 with the opening 41 of the housing 31 closed by the connector 32. For example, the electronic control device 20 injects the potting material 70 from the injection port 32a1 in a state where the injection port 32a1 is disposed above the bottom portion 40.

  The electronic control unit 20 is fixed to the bracket 33. The bracket 33 is a member for attaching the housing 31 in which the circuit boards 30 a and 30 b are accommodated to the vehicle 10. In other words, the bracket 33 is a member for attaching the electronic control device 20 to the vehicle. That is, the electronic control device 20 is attached to the vehicle 10 via the bracket 33. Further, the electronic control device 20 may be provided with a heat transfer member between the housing 31 and the bracket 33 in order to dissipate its own heat from the housing 31 to the bracket 33.

  The bracket 33 has at least a metal interposition part 50 and a pair of metal leaf spring parts 51. The pair of leaf spring portions 51 corresponds to a pair of folded portions.

  The interposition part 50 is interposed between the flat part 19 d (short side surface 19 c) of the battery 19 and the facing surface 43 b of the housing 31. Since the interposition part 50 connects a pair of leaf | plate spring parts 51, it can also be called a connection part. Moreover, since the leaf | plate spring part 51 is each connected to the Y direction both ends, the interposition part 50 can also be called a base (base).

  The leaf spring portion 51 extends from the both ends of the interposition portion 50 in the Y direction toward the back surface 43c in the X direction, and is folded back with respect to the interposition portion 50 so as to face the interposition portion 50 in the X direction. The leaf spring portion 51 folded back in this way can be spring-deformed in the X direction. A pair of leaf | plate spring part 51 respectively contacts the slope part 43e of a pair of connection surface 43d by the said folding structure, and provides the reaction force by a spring deformation | transformation to the corresponding slope part 43e. Spring deformation is also referred to as elastic deformation. The slope portion 43e is a portion where the leaf spring portion 51 of the bracket 33 contacts, and the contact position is a position between the back surface 43c and the facing surface 43b in the X direction. Therefore, the inclined surface portion 43 e corresponds to a receiving portion that receives the leaf spring portion 51 in the housing 31.

  The connection method of the leaf | plate spring part 51 and the interposition part 50 is not specifically limited. The interposition part 50 and the leaf | plate spring part 51 may be comprised by another member, and may be connected by welding, for example. In this embodiment, as shown in FIG. 8, the bracket 33 is formed by processing a flat metal plate into a predetermined shape. That is, the leaf | plate spring part 51 and the interposition part 50 are integrally connected as a part of the same metal plate. In FIG. 8, the boundary (connection part) between the interposition part 50 and the leaf | plate spring part 51 is shown with the broken line. The other boundaries are also indicated by broken lines.

  The leaf spring portions 51 are provided at both ends of the interposition portion 50 in the Y direction, and are bent to the opposite side of the interposition portion 50 from the battery 19. Specifically, the leaf spring portion 51 has an acute angle with the interposition portion 50 so as to contact the slope portion 43e of the housing 31. The leaf spring portion 51 has a bent portion (bent portion) at the connection end with the interposition portion 50, thereby contacting the corresponding slope portion 43 e and applying a reaction force due to spring deformation to the slope portion 43 e. Can be granted. That is, the leaf spring portion 51 is bent with respect to the interposition portion 50 so as to press the slope portion 43e. The pair of slope portions 43 e is pressed by the pair of leaf spring portions 51. For this reason, the housing 31 is fixed by the leaf spring portion 51. In other words, the electronic control device 20 is held (fixed) to the bracket 33 by the inclined surface portion 43e being pressed by the leaf spring portion 51. The leaf spring portion 51 can also be referred to as a fixed portion 51.

  In the present embodiment, as shown in FIGS. 3 and 4, the leaf spring portion 51 is connected to only a part of the interposition portion 50 in the Z direction. Specifically, in the Z direction, the leaf spring portion 51 is connected only to a portion within a predetermined range from the upper end of the interposition portion 50 from the upper end to the lower end, and is not connected to a partial range upward from the lower end. However, the leaf spring portion 51 may be connected from the upper end to the lower end of the interposition portion 50. The bending angle of the leaf spring part 51 with respect to the interposition part 50 is substantially constant in the Z direction.

  Further, the bracket 33 may be configured such that, for example, a protrusion is provided on a portion of the leaf spring portion 51 facing the slope portion 43e, and the protrusion comes into contact with the slope portion 43e. According to this, the contact area between the leaf spring portion 51 and the slope portion 43e can be reduced, and the housing 31 including the circuit boards 30a and 30b and the connector 32 can be easily attached to the bracket 33. When the housing 31 and the bracket 33 are fixed, the circuit board 30a, 30b is accommodated in the housing 31, and the connector 32 is mounted on the circuit board 30a, 30b. Therefore, strictly speaking, the housing 31 including the circuit boards 30a and 30b and the connector 32 and the bracket 33 are fixed. However, in the following, it will be shown that the casing 31 and the bracket 33 are simply fixed. It can also be said that the electronic control unit 20 and the bracket 33 are fixed.

  Further, in the present embodiment, as shown in FIGS. 3 and 7, the bracket 33 includes a support portion 52 and a tray portion 54. The support part 52 and the tray part 54 are connected to other parts constituting the bracket 33. As a constituent material of the support portion 52 and the tray portion 54, at least one of a metal material and a resin material can be employed. The bracket 33 is formed by integrally forming the support portion 52 and the tray portion 54 of a resin material, and fixing a metal member having the interposition portion 50 and the leaf spring portion 51 to the formed member by, for example, press-fitting. You may connect. In addition, the bracket 33 is a metal having the interposition part 50, the leaf spring part 51, and the support part 52 by connecting the support part 52 formed using a metal material to either the interposition part 50 or the leaf spring part 51. The member may be press-fitted and fixed to the tray portion 54 formed of resin. Moreover, the bracket 33 may connect the support part 52 formed using the metal material and the tray part 54 formed using the metal material, for example, by welding. Furthermore, the bracket 33 may connect the support part 52 and the tray part 54 formed using a metal material to the interposition part 50 and the leaf spring part 51 by welding or the like.

  In the present embodiment, as described above, the bracket 33 is configured by processing a flat metal plate into a predetermined shape. That is, not only the interposition part 50 and the leaf | plate spring part 51 but the support part 52 and the tray part 54 are comprised as a part of the same metal plate.

  As shown in FIGS. 3, 5, 7, and 11, the support portion 52 supports the bottom portion 40 of the housing 31. In the present embodiment, a through hole 53 for screwing the housing 31 is formed in the support portion 52. 5 is fixed to the support portion 52 by inserting the screw 34 shown in FIG. 5 through the through hole 53 and screwing into the screw hole 44 formed in the bottom portion 40 of the housing 31.

  Moreover, the support part 52 is connected with the baseplate part 55 which comprises the tray part 54, as shown in FIG.5 and FIG.11. In FIG. 5, the boundary between the support portion 52 and the bottom plate portion 55 is indicated by a broken line. The support portion 52 is an end portion in the X direction of the bottom plate portion 55 and is connected to the vicinity of both ends in the Y direction. The support portion 52 overlaps the vicinity of both ends in the Y direction at the bottom portion 40 of the housing 31 in the projection view from the Z direction.

  The tray portion 54 is a portion of the bracket 33 where the battery 19 is disposed. The tray portion 54 has a bottom plate portion 55 and horizontal plate portions 56 and 57. It can be said that the bottom plate portion 55 is a support portion and the horizontal plate portion 57 is a reinforcement portion. In the present embodiment, the bottom plate portion 55 and the horizontal plate portions 56 and 57 are also configured as part of the metal plate that constitutes the interposition portion 50, the leaf spring portion 51, and the support portion 52. That is, in the present embodiment, the bottom plate portion 55 and the horizontal plate portions 56 and 57 are configured as a part of the same metal plate. However, the bottom plate portion 55 and the horizontal plate portions 56 and 57 can be separate members. Furthermore, the horizontal plate portion 56 and the horizontal plate portion 57 may be separate members.

  The bottom plate part 55 supports the battery 19. The bottom plate portion 55 has a rectangular shape (rectangular shape) corresponding to the battery 19 in the shape of the XY plane. As described above, the support portion 52 is connected to one end of the bottom plate portion 55 in the X direction, that is, one of the end portions corresponding to the short side surface 19 c of the battery 19. Further, the bottom plate portion 55 is connected to the lower end of the interposition portion 50 between the two support portions 52 at the end where the support portion 52 is connected. The support portion 52 is located on the same plane as the bottom plate portion 55 and extends from the bottom plate portion 55 in the X direction. That is, the support portion 52 is not bent with respect to the bottom plate portion 55. On the other hand, the interposition part 50 is bent with respect to the bottom plate part 55 so that the angle formed with the bottom plate part 55 is approximately 90 degrees.

  The bottom plate portion 55 has a fixing hole 58 formed so as to penetrate near the center. With the fixing hole 58, the bracket 33, that is, the electronic control unit 20, is screwed to the body of the vehicle 10 or an attachment portion fixed to the body. Note that the fixed portion of the electronic control device 20 to the vehicle 10 is not limited to the bottom plate portion 55. The electronic control unit 20 can be fixed at other portions of the bracket 33. Further, the electronic control device 20 can be fixed to an attachment portion such as a radiator support via the clamp member 24.

  The horizontal plate portion 56 is connected to the end portion of the bottom plate portion 55 opposite to the end portion to which the interposition portion 50 and the support portion 52 are connected. The horizontal plate portion 56 has a rectangular shape (rectangular shape) on the YZ plane, and has the same length as the bottom plate portion 55 in the Y direction. The horizontal plate portion 56 is bent with respect to the bottom plate portion 55 so that the angle formed with the bottom plate portion 55 is approximately 90 degrees. As shown in FIG. 7, the interposition part 50 and the horizontal plate part 56 face each other.

  The pair of horizontal plate portions 57 is connected to the end portion in the Y direction of the bottom plate portion 55, that is, the end portion corresponding to the long side surface 19 b of the battery 19. The pair of horizontal plate portions 57 are bent with respect to the bottom plate portion 55 so that the angle formed with the bottom plate portion 55 is approximately 90 degrees. The pair of horizontal plate portions 57 face each other. One end of the horizontal plate portion 57 in the X direction is connected to an end portion of the horizontal plate portion 56 in the Y direction, for example, by welding.

  Moreover, as shown in FIG. 7, the other end of the X direction in the horizontal plate part 57 is connected with the edge part of the Y direction in the interposition part 50, for example by welding. That is, the lateral plate portion 57 extends to the opposite side of the leaf spring portion 51 in the X direction with respect to the interposition portion 50. The facing interval between the pair of horizontal plate portions 57 is held by the interposition portion 50 and the horizontal plate portion 56. Since the bracket 33 surrounds the periphery of the bottom plate portion 55 by the interposition portion 50 and the horizontal plate portions 56 and 57, the positioning of the battery 19 is easy and the displacement of the battery 19 can also be suppressed.

  However, the lateral plate portion 57 can also be connected to the leaf spring portion 51 by welding, for example. In this case, the thickness of the electronic control device 20 can be made thinner in the X direction by the thickness of the horizontal plate portion 57 than in the configuration shown in FIG.

  The height in the Z direction of the horizontal plate portion 57 is substantially the same as that of the horizontal plate portion 56 in a predetermined range in the X direction from the connecting end with the horizontal plate portion 56, specifically, in a range from the vicinity of the center in the X direction. It is height. On the other hand, at the end on the interposition part 50 side, the height of the horizontal plate part 57 is substantially the same as that of the interposition part 50. The height of the horizontal plate portion 57 gradually increases from the vicinity of the center in the X direction toward the end portion on the interposed portion 50 side. Thus, the height of the horizontal plate portion 57 is higher on the side closer to the circuit boards 30a and 30b in the X direction. Further, the horizontal plate portion 57 is formed with a latching portion 59 around which the J-shaped lower end portion of the hook member 25 is latched near the center in the X direction.

  Next, a procedure for assembling the electronic control device 20 to the vehicle 10 will be described with reference to FIG.

  First, the main wire including the relay box 21 and the wire harness 23 is arranged in the engine compartment 17.

  Next, the engine module is installed in the engine compartment 17 from the lower side of the vehicle 10. The engine module is constructed by assembling the engine 18 with auxiliary equipment such as a starter, alternator and compressor, a drive system such as a transmission and a drive shaft, a braking system such as a shock absorber and a brake rotor, and an intake and exhaust system excluding an air cleaner. is there. Further, in addition to these, the engine module may be assembled with an engine mounting component, an under cover, and a wire harness 22.

  Next, the remaining parts such as the remaining wire harness excluding the main wire and the wire harness 22, the air cleaner, the electronic control unit 20, and the battery 19 are assembled. That is, the battery 19 and the electronic control unit 20 are assembled between the engine 18 and the relay box 21 with the engine 18 and the relay box 21 already arranged.

  At that time, the housing 31 is disposed beside the short side surface 19 c of the battery 19 so that the connector 32 is positioned above the bottom 40 of the housing 31. Then, the electronic control device 20 (bracket 33) is assembled to the body of the vehicle 10 or an attachment portion fixed to the body, and then the battery 19 is disposed on the bottom plate portion 55 of the bracket 33. Further, the female connector on the external device side is fitted into the connector 32. Thereby, the wire harnesses 22 and 23 are connected to the circuit boards 30a and 30b. The female connector can be fitted before the battery 19 is arranged.

  Next, effects of the electronic control device 20 described above will be described.

  In the present embodiment, the connecting surface 43d of the housing 31 is not a surface along the X direction, but the distance between the pair of connecting surfaces 43d in the Y direction becomes narrower as at least a part of the connecting surface 43d approaches the back surface 43c. It is set as the slope part 43e which inclines so that it may become. That is, in the present embodiment, the casing 31 is not substantially rectangular when viewed from the Z direction, but the distance between the pair of connection surfaces 43d in the Y direction increases as the back surface 43c approaches at least a part of the connection surface 43d. It is set as the slope part 43e which inclines so that it may become narrow.

  At the same time, in the present embodiment, a metal leaf spring portion 51 is provided on the bracket 33 so as to come into contact with the slope portions 43e of the pair of connecting surfaces 43d and to apply a reaction force due to spring deformation to the slope portions 43e. . When a reaction force due to spring deformation acts on the slope portion 43e, the slope portion 43e is pushed to the opposite slope portion 43e side in the Y direction and to the intervention portion 50 side in the X direction. That is, both ends of the housing 31 in the Y direction are pushed toward the interposition part 50 in the X direction. And the housing | casing 31 is clamped in the X direction by the leaf | plate spring part 51 and the interposition part 50. FIG. In this way, the housing 31 can be fixed to the bracket 33. Therefore, compared to a conventional structure, for example, a structure in which the bracket is screwed to the housing in the X direction, or a structure in which the connection surface is not a slope but a surface along the thickness direction, and the opposite surface and the back surface are sandwiched and fixed by the bracket. The electronic control unit 20 can be made thinner in the direction. Moreover, since it fixes by holding, fixing structure can be simplified.

  Since the electronic control unit 20 can be thinned as described above, the electronic control unit 20 can be arranged in the narrow space next to the flat portion 19 d of the battery 19, that is, the side of the battery 19 in the engine compartment 17 where the mounting space is limited. Thereby, compared with the structure which arrange | positions an electronic controller under a battery, the position of the bonnet 12 located above the engine compartment 17 can be made low. Therefore, the position of the center of gravity of the vehicle 10 can be lowered. Moreover, since the freedom degree of the shape of the bonnet 12 improves, it becomes easy to change the shape of the bonnet 12, and the design property can also be improved. In this embodiment, since the electronic control unit 20 is disposed in the engine compartment 17, the visibility (parting) of the driver can be further improved.

  Further, the opening 41 of the housing 31, in other words, the connector 32 is arranged so as to be above the bottom 40. Therefore, it is not necessary to route the wire harness from the lower side to the upper side as in the configuration in which the electronic control device is arranged under the battery. Furthermore, the length of the wire harnesses 22 and 23 can be shortened.

  As described above, according to the present embodiment, in the electronic control device 20 arranged next to the battery 19, the position of the bonnet 12 on the engine compartment 17 is increased while suppressing the wire harnesses 22 and 23 from becoming longer. Can be suppressed.

  Further, the heat of the circuit boards 30 a and 30 b is transmitted to the interposition part 50 and the leaf spring part 51 through the metal casing 31. Therefore, the heat of the circuit boards 30a and 30b can be efficiently radiated by the metallic interposition part 50 and the leaf spring part 51. In addition, the lower part of the engine compartment 17 has transmissions and exhaust system parts, and the under cover for improving running stability makes it difficult for wind to flow. . Therefore, the heat of the circuit boards 30a and 30b can be radiated more efficiently than the configuration in which the electronic control device is disposed under the battery.

  Further, the electronic control device 20 is provided with a positioning hole 30a1 in the first circuit board 30a. The electronic control unit 20 can suppress the displacement of the circuit element 30c by inserting a part of the circuit element 30c into the positioning hole 30a1. In addition, the electronic control unit 20 includes a second circuit board 30b that presses the circuit element 30c disposed in the positioning hole 30a1 of the first circuit board 30a against the first circuit board 30a. That is, the electronic control device suppresses the positional deviation of the circuit element 30c by the positioning hole 30a1 and the second circuit board 30b. Therefore, even when an external force is applied to the circuit element 30c, the electronic control device 20 is unlikely to shift the position of the circuit element 30c. As described above, the electronic control device 20 can improve the durability of the element-side terminal 30c1 and the solder 60, which are connection portions between the circuit element 30c and the first circuit board 30a, because the circuit element 30c is not easily displaced. Furthermore, since a part of the circuit element 30c is inserted into the positioning hole 30a1, the electronic control device 20 can be reduced in thickness accordingly. Therefore, the electronic control device 20 can be easily placed in a narrow space beside the battery 19. The electronic control device 20 can achieve this effect even if it does not include the housing 31 and the connector 32. In addition, the electronic control device 20 can achieve this effect even if the potting material 70 is not provided.

  In the electronic control device 20, a potting material 70 that covers the first circuit board 30 a and the circuit element 30 c is provided in the housing 31. It is conceivable that the potting material 70 is poured into the casing 31 when it is provided in the casing 31. In this case, since the potting material 70 that flows into the housing 31 hits the circuit element 30c, an external force is applied by the potting material 70. However, as described above, the electronic control device 20 suppresses the displacement of the electronic component by the positioning hole 30a1 and the second circuit board 30b. The element 30c is difficult to be displaced. Therefore, the electronic control unit 20 can suppress the sealing with the potting material 70 in a state where the circuit element 30c is displaced.

  For example, when the circuit element 30c is displaced, stress may be applied to the element-side terminal 30c1 or the solder 60. Therefore, when the circuit element 30c is sealed with the potting material 70 while being displaced, the circuit element 30c is fixed to the first circuit board 30a in a state where stress is applied to the element-side terminal 30c1 and the solder 60. For this reason, the element side terminal 30c1 and the solder 60 are liable to break the element side terminal 30c1 or to crack the solder 60. However, since the electronic control unit 20 can suppress the circuit element 30c from being fixed in a misaligned state, the durability of the element-side terminal 30c1 and the solder 60 is improved even when the potting material 70 is provided. it can.

  As described above, the electronic control device 20 includes the first circuit board 30a and the second circuit board 30b. The second circuit board 30 b is accommodated in the housing 31, is disposed to face the mounting surface of the first circuit board 30 a, and is covered with the potting material 70. As described above, the second circuit board 30b is disposed to face the mounting surface of the first circuit board 30a. Therefore, in the present embodiment, the second circuit board 30b is employed as a pressing member. For this reason, the second circuit board 30b is provided so as to press the circuit element 30c against the first circuit board 30a. In the present embodiment, since the second circuit board 30b, which is a component provided in the electronic control device 20, is employed as the pressing member, the circuit element 30c is pressed against the first circuit board 30a without increasing the number of components. Can do.

  The circuit element 30c has a cylindrical body part, and is arranged so that the cylindrical part is parallel to the mounting surface and the circular wall part is perpendicular to the mounting surface. Normally, such a circuit element 30c is likely to be displaced when an external force is applied only by inserting the element-side terminal 30c1 into the first circuit board 30a. However, since the electronic control unit 20 suppresses the positional deviation of the circuit element 30c by the positioning hole 30a1 and the second circuit board 30b, the positional deviation can be suppressed even by such a circuit element 30c.

  Furthermore, in this embodiment, the shape of the housing | casing 31 is made into trapezoid shape seeing from a Z direction. That is, the substantially entire surface of the connecting surface 43d is a slope portion 43e. According to such a configuration, it is easy to fix the housing 31 and the bracket 33. For example, in a state where the pair of leaf springs 51 is slightly opened by applying an external force, the housing 31 is moved to a predetermined position in the Z direction, and then the application of the external force is canceled, so that the housing 31 and the bracket 33 Can be fixed. Further, the connecting surface 43d can form the housing 31 more easily than a configuration in which the connection surface 43d has a slope portion 43e only in a part and the remaining portion is along the X direction (that is, does not have the slope portion 43e). If the angle between the leaf spring portion 51 and the interposition portion 50 is reduced within a predetermined range from the upper end toward the lower end, the casing 31 can be moved to a predetermined position without applying external force. Can be moved. In addition, as described above, even when a protrusion such as a wedge shape or a hemisphere is provided on the contact surface side of the leaf spring portion 51, the casing 31 is fixed to the predetermined portion without opening the leaf spring portion 51 by applying an external force. It can be moved to a position.

  Furthermore, in the present embodiment, the bracket 33 has a support portion 52, and the housing 31 is supported by the support portion 52. Therefore, it is possible to prevent the casing 31 from being displaced downward with the application of vehicle vibration. That is, the housing 31 can be fixed more stably. In particular, in the present embodiment, a through hole 53 is formed in the support portion 52, and the housing 31 is screwed to the support portion 52 through the through hole 53. As described above, since the screw is fastened under the bottom portion 40 of the housing 31, it is difficult to remove the housing 31 from the bracket 33, that is, the vehicle 10. Therefore, it is possible to prevent the housing 31 including the circuit boards 30a and 30b from being taken out (for example, stolen) from the engine compartment 17. In particular, in the present embodiment, since the support portion 52 is formed using a metal material, the heat of the circuit boards 30 a and 30 b is also transmitted to the support portion 52 through the bottom portion 40 of the metal casing 31. Therefore, the heat of the circuit boards 30a and 30b can be radiated efficiently.

  Furthermore, in the present embodiment, the bracket 33 has a horizontal plate portion 57. The lateral plate portion 57 is connected to the interposed portion 50 or the leaf spring portion 51 and extends in a direction opposite to the direction in which the leaf spring portion 51 extends from the interposed portion 50. Therefore, it is possible to prevent the leaf spring portion 51 and the interposition portion 50 from falling due to the weight of the circuit boards 30a, 30b, the casing 31, and the like. That is, the casing 31 including the circuit boards 30 a and 30 b can be stably held by the side of the battery 19. In particular, in the present embodiment, since the horizontal plate portion 57 is formed using a metal material, the heat of the circuit boards 30 a and 30 b is also transmitted to the horizontal plate portion 57. Thus, the thermal mass of the entire bracket 33 is increased, and the heat of the circuit boards 30a and 30b can be radiated more effectively. The thermal mass indicates a volume capable of absorbing heat.

  Further, in the present embodiment, the bracket 33 has the bottom plate portion 55 and can support the battery 19. In particular, in the present embodiment, since the bottom plate portion 55 is formed using a metal material, the heat of the circuit boards 30 a and 30 b is also transmitted to the bottom plate portion 55. Thus, the thermal mass of the entire bracket 33 is increased, and the heat of the circuit boards 30a and 30b can be radiated more effectively. In other words, in the present embodiment, the horizontal plate portion 57 and the bottom plate portion 55 can be used as a heat dissipation path for the heat propagated to the bracket 33.

  In the present embodiment, the tray portion 54 is configured including the bottom plate portion 55 and the horizontal plate portion 57, and the battery 19 can be supported by the bracket 33 in addition to the housing 31. In particular, in this embodiment, the interposition part 50, the leaf spring part 51, the support part 52, and the components (the bottom plate part 55, the lateral plate parts 56, 57) of the tray part 54 that supports the battery 19 are the same metal plate. Is configured as part of Therefore, the configuration of the bracket 33 including the tray portion 54 can be simplified. Further, the heat of the circuit boards 30 a and 30 b can be radiated to the entire tray portion 54. In other words, in the present embodiment, the tray portion 54 can be used as a heat dissipation path for the heat propagated to the bracket 33.

  Furthermore, in this embodiment, the housing | casing 31 of the electronic control apparatus 20 is arrange | positioned beside the battery 19 as a box-shaped member. In the engine compartment 17, the battery 19 is disposed not in the vicinity of the engine 18 but in a place where the temperature from the front grill 15 is low. Therefore, by arranging the circuit boards 30a and 30b beside the battery 19, the temperature rise of the circuit boards 30a and 30b can be effectively suppressed.

  By the way, it is also possible to arrange | position the housing | casing 31 next to the long side surface 19b among the side surfaces of the battery 19. FIG. However, if arranged next to the long side surface 19b, the wire harnesses 22 and 23 must be routed so as to avoid the hook member 25. For this reason, the length of the wire harnesses 22 and 23 becomes long. In addition, a space for wiring is required. On the other hand, in this embodiment, since the housing | casing 31 is arrange | positioned next to the short side surface 19c of the battery 19, the length of the wire harnesses 22 and 23 can also be shortened by this.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. Below, the modification of this invention is demonstrated. The above-described embodiments and modification examples can be implemented independently, but can be implemented in combination as appropriate. The present invention is not limited to the combinations shown in the mode for carrying out the invention, and can be implemented in various combinations.

(Modification 1)
In this modification, the description of the parts common to the electronic control device 20 shown in the above embodiment is omitted.

  As shown in FIG. 17, in the electronic control device of Modification 1, not only the first circuit board 30a but also the second circuit board 30d is provided with positioning holes 30d1. The second circuit board 30d is provided with a positioning hole 30d1 penetrating in the thickness direction of the second circuit board 30d. The second circuit board 30d has a positioning hole 30d1 at a position facing the positioning hole 30a1. The positioning hole 30d1 corresponds to the second hole in the claims. FIG. 17 corresponds to FIG.

  The electronic control device of Modification 1 can achieve the same effects as the electronic control device 20. Furthermore, in the electronic control device according to the first modification, not only a part of the circuit element 30c is embedded in the first circuit board 30a but also another part of the circuit element 30c is embedded in the second circuit board 30d. The thickness can be made thinner than that of the electronic control unit 20. Further, in the electronic control device according to the first modification, since the circuit element 30c is embedded in both the positioning holes 30a1 and 30d1, the fixing strength can be improved as compared with the electronic control device 20.

  The positioning hole 30d1 may be a concave portion that is recessed from the periphery, instead of a portion that penetrates in the thickness direction of the second circuit board 30d. Similarly, the positioning hole 30a1 may not be a part penetrating in the thickness direction of the first circuit board 30a but may be a concave part recessed from the periphery.

(Modification 2)
In this modification, the description of the parts common to the electronic control device 20 shown in the above embodiment is omitted.

  As shown in FIG. 18, unlike the electronic control device 20, the electronic control device 20a of Modification 2 is not provided with the second circuit board 30b. For this reason, the connector 321 has the first terminal 32b like the connector 32, but unlike the connector 32, the connector 321 does not have the second terminal 32c. That is, the housing 321a is provided with the first terminal 32b and is not provided with the second terminal 32c.

  In the electronic control device 20a, a portion of the housing 31a that faces the mounting surface of the first circuit board 30a is in contact with the circuit element 30c. That is, in the electronic control unit 20a, the casing 31a presses the circuit element 30c against the first circuit board 30a. Thus, the housing | casing 31a is provided with the site | part corresponded to the pressing member in a claim. That is, the part of the housing 31a that faces the mounting surface of the first circuit board 30a corresponds to the pressing member in the claims. The electronic control device 20a can achieve the same effects as the electronic control device 20.

(Modification 3)
In this modification, the description of the parts common to the electronic control device 20 shown in the above embodiment is omitted.

  As illustrated in FIGS. 19 and 20, the electronic control device 20 b of Modification 3 is different from the electronic control device 20 in the configuration of the first circuit board 30 e and the configuration of the circuit element 30 f. FIG. 20 is a view of FIG. 19 viewed from the Z direction.

  The first circuit board 30e is provided with a positioning hole 30e1 that is recessed from the periphery. Thus, the first circuit board 30e is different from the first circuit board 30a in the shape of the positioning hole 30e1. That is, the positioning hole 30e1 is not a part penetrating in the thickness direction of the first circuit board 30e, but a concave part recessed from the periphery. The first circuit board 30e is formed with a through hole 30e2 into which the element side terminal 30f1 is inserted, like the first circuit board 30a.

  The circuit element 30f is mounted on the mounting surface side of the first circuit board 30e by electrically and mechanically connecting the element side terminal 30f1 and the first circuit board 30e via the solder 60. Unlike the circuit element 30c, the circuit element 30f has a cubic shape. In this modification, a THD inductor is used as the circuit element 30f. More specifically, the circuit element 30f has a cube-shaped body portion and two element-side terminals 30f1 protruding from the body portion. That is, the body part of the circuit element 30f has a shape including a cylindrical part and rectangular wall parts formed at both ends of the cylindrical part. The circuit element 30f is formed such that each element-side terminal 30f1 protrudes from one of the two rectangular walls. Each element side terminal 30f1 is L-shaped like each element side terminal 30c1. Similarly to the circuit element 30c, the circuit element 30f is mounted horizontally with respect to the first circuit board 30e.

  The electronic control device 20b can achieve the same effects as the electronic control device 20. The electronic control device 20b may include a circuit element 30c instead of the circuit element 30f.

(Modification 4)
In this modification, the description of the parts common to the electronic control device 20 shown in the above embodiment is omitted.

  As shown in FIGS. 21 and 22, the electronic control device of Modification 4 is different from the electronic control device in the configuration of the first circuit board 30 g and the configuration of the circuit element 30 h.

  As shown in FIG. 21, the first circuit board 30g is provided with a positioning hole 30g1 that is recessed from the periphery, like the first circuit board 30e. Further, as shown in FIG. 22, the first circuit board 30g has a conductive land 30g2 formed on the surface of the positioning hole 30g1. Here, the first circuit board 30g on which two lands 30g2 are formed is employed. In addition, the first circuit board 30g is provided with a positioning hole 30g1 for suppressing displacement of the circuit element 30h in a direction orthogonal to the facing direction of the two lands 30g2 on a plane along its mounting surface. ing.

  The circuit element 30h includes a cylindrical body part, like the circuit element 30c. However, unlike the circuit element 30c, the circuit element 30h has an SMD (Surface Mount Device) structure. For example, the circuit element 30h is an SMD aluminum electrolytic capacitor. As shown in FIG. 22, the circuit element 30h has two electrodes 30h1 formed on a circular wall portion. The circuit element 30h is mounted on the first circuit board 30g with the circular wall portion facing the mounting surface of the first circuit board 30g. The circuit element 30h is mounted on the first circuit board 30g in a state where the electrode 30h1 and the land 30g2 are electrically and mechanically connected via a solder 60 (not shown).

  Note that the electronic control device of Modification 4 is not shown, but the circuit element 30h is pressed against the first circuit board 30g by the second circuit board 30b or the casing 31a. Furthermore, the electronic control device according to the modified example 4 can also be used in the circuit element 30h having a THD structure in which the terminals protrude perpendicularly to the circular wall portion. The electronic control device according to the modified example 4 can achieve the same effects as the electronic control device 20.

(Modification 5)
In this modification, the description of the parts common to the electronic control device 20 shown in the above embodiment is omitted. As shown in FIG. 23, the connector 32 and the casing 31 of the electronic control device 20c are different in shape from those in the electronic control device 20, but are given the same reference numerals for convenience.

  As shown in FIG. 23, the electronic control unit 20c of the fifth modification employs a component carrier 35 as a pressing member. The component carrier 35 has a wiring pattern and a heating element 35b built in a resin housing 35a, and is electrically connected to the first circuit board 30a using pins 35c. Further, the heat generating element 35 b may be brought into contact with the housing 31 with the heat radiating gel 80. For the component carrier 35, refer to Japanese Patent Application Laid-Open No. 2005-333077.

  Thus, in the electronic control unit 20c, the component carrier 35 presses the circuit element 30c against the first circuit board 30a. The electronic control device 20c can achieve the same effects as the electronic control device 20.

(Modification 6)
For this modification, reference can be made to the preceding embodiment and the preceding modification. For this reason, the description about the part which is common in the electronic control apparatus 20 etc. which were shown in the preceding embodiment and the previous modification is abbreviate | omitted.

  First, based on FIGS. 24 to 27, the electronic control device 20 d of Modification 6, particularly the housing 31 b including the first circuit board 30 a and the connector 32 will be described. 26 and 27, the terminal 32b of the connector 32 is omitted for convenience.

  The casing 31b of the present modification is disposed on the opposite side of the upper case 82 with respect to the intermediate case 81, the upper case 82 disposed on one surface side in the X direction with respect to the intermediate case 81. And a lower case 83. That is, the housing 31b is configured by a plurality of members. The intermediate case 81, the upper case 82, and the lower case 83 correspond to a casing constituent member. The intermediate case 81, the upper case 82, and the lower case 83 are configured to be divided in the vertical direction. Further, the housing 31b has a pair of receiving portions 84 that are portions where the leaf spring portion 51 contacts.

  The intermediate case 81 is a resin molded body. In this modification, the intermediate case 81 is formed using a thermoplastic resin. As the thermoplastic resin, one having excellent heat resistance, such as polybutylene terephthalate (PBT) can be employed.

  The intermediate case 81 has an annular shape and has a through hole 81a along the X direction. For this reason, intermediate case 81 can also be called a frame. Specifically, as shown in FIGS. 25 and 26, the intermediate case 81 has a substantially rectangular ring shape. 24, the housing 32a of the connector 32 is integrated with the intermediate case 81. As shown in FIG. In other words, the housing 32 a is integrally formed as a part of the intermediate case 81. However, the shape of the intermediate case 81 is not limited to the above example. For example, a substantially C-shaped (in other words, approximately U-shaped) intermediate case 81 may be employed, and a configuration in which the housing 32a is disposed in the C-shaped opening (gap portion) of the intermediate case 81 may be employed. . In this case, the intermediate case 81 and the housing 32a can be sealed by welding.

  As shown in FIGS. 25 and 26, the intermediate case 81 includes a frame portion 85 having a substantially rectangular ring shape, and pedestal portions 86 provided at four corners on the inner peripheral side of the frame portion 85. . In FIG. 25, the inner peripheral end 81b of the intermediate case 81 is indicated by a broken line, and in FIG. 26, the pedestal portion 86 is indicated by a broken line. The thickness of the frame portion 85 in the X direction is substantially constant over the entire circumference. The pedestal portion 86 is substantially flush with the frame portion 85 on the upper case 82 side, and is provided at a position lower than the frame portion 85 on the lower case 83 side. That is, the thickness of the pedestal portion 86 is made thinner than the thickness of the frame portion 85. Thereby, a predetermined gap is provided between the pedestal portion 86 and the lower case 83.

  As shown in FIGS. 24 and 26, the first circuit board 30a is disposed on the surface of the pedestal portion 86 on the lower case 83 side, and is fixed to the pedestal portion 86 (intermediate case 81). The method for fixing the first circuit board 30a is not particularly limited. For example, adhesion or screw fastening can be employed. In the state where the first circuit board 30 a is fixed to the intermediate case 81, a predetermined gap is provided between the first circuit board 30 a and the lower case 83.

  The upper case 82 is formed using a metal material. In this modification, the upper case 82 has a flat plate shape. The upper case 82 is fixed to the frame portion 85 and the pedestal portion 86 so as to close one open end of the through hole 81a. The outer contour of the upper case 82 substantially coincides with the outer peripheral end of the intermediate case 81 in the projection view from the X direction. Therefore, the upper case 82 constitutes the side wall portion 42 on the back surface 43c side. That is, the surface of the upper case 82 opposite to the intermediate case 81 forms the back surface 43c.

  The fixing method of the upper case 82 is not particularly limited. In this modification, the upper case 82 is welded to the intermediate case 81. When welding is used, a sealing material between the upper case 82 and the intermediate case 81 can be made unnecessary. An anchor effect can be expected when the upper case 82 is a surface in which at least the welded surface of the intermediate case 81 is roughened (etched) by etching or the like. In addition, the leak path becomes longer and the waterproofness can be improved.

  As shown in FIG. 24, the upper case 82 is in contact with the circuit element 30c and presses the circuit element 30c against the first circuit board 30a. That is, in the electronic control unit 20d, it can be said that the upper case 82, which is a part of the housing 31b facing the mounting surface of the first circuit board 30a, is in contact with the circuit element 30c. Therefore, in the electronic control unit 20d, the casing 31b presses the circuit element 30c against the first circuit board 30a. Thus, the upper case 82 corresponds to a pressing member in the claims.

  Similarly to the upper case 82, the lower case 83 is also formed using a metal material. As shown in FIGS. 24, 25, and 27, the lower case 83 includes a main body portion 87 that closes one open end of the through hole 81 a and an extending portion 88 that extends from the main body portion 87. .

  The main body 87 has a flat plate shape. The main body 87 is fixed to the frame 85 so as to close the opening end of the through hole 81a opposite to the upper case 82. The outer contour of the main body 87 substantially coincides with the outer peripheral end of the intermediate case 81 in the projection view from the X direction. The fixing method of the main body 87 (lower case 83) is not particularly limited. The main body 87 is also welded to the intermediate case 81. Therefore, as the lower case 83, it is preferable to employ a roughened at least welded portion of the surface on the intermediate case 81 side.

  The extended portion 88 is a portion that extends outward from the main body portion 87 along the Y direction from both ends of the main body portion 87 in the Y direction. The extending portions 88 are provided on both sides of the main body portion 87 in the Y direction. The extending portion 88 is composed of a separate member from the main body portion 87, and may be connected to the main body portion 87 by welding, for example. In this modification, the main body portion 87 and the extending portion 88 are integrally connected as a part of a metal plate having a predetermined thickness, and the extending portion 88 has the same thickness as the main body portion 87. It is located in the same plane as the main body 87. Since the receiving portion 84 is provided on the extending portion 88, the length of the extending portion 88 in the Z direction is determined according to the length of the receiving portion 84 in the Z direction.

  The main body portion 87 and the extending portion 88, that is, the lower case 83 constitute the side wall portion 42 on the facing surface 43 b side. Therefore, the surface opposite to the intermediate case 81 in the lower case 83 forms the facing surface 43b. The intermediate case 81, the upper case 82, and the lower case 83 constitute the bottom wall portion 40.

  A pair of receiving part 84 is a part which the leaf | plate spring part 51 of the bracket 33 contacts among the housing | casing 31b. In other words, the receiving part 84 is a part which receives the leaf | plate spring part 51 among the housing | casing 31b. The receiving portion 84 is provided at the portion of the extending portion 88 in the surface opposite to the facing surface 43 b in the lower case 83. For this reason, the receiving portion 84 can be said to be a part of the lower case 83. Since the receiving part 84 protrudes from the extending part 88 in the X direction, it is also referred to as a convex part. The protruding tip of the receiving portion 84 is a position between the facing surface 43b and the back surface 43c in the X direction. The receiving portion 84 is provided in each of the pair of extending portions 88 located on both sides of the main body portion 87. For this reason, the back surface 43c is located between the pair of receiving portions 84 in the Y direction.

  In this modification, the receiving part 84 is comprised by the extension part 88 and another member, and is being fixed to the extension part 88 by welding, for example. The receiving portion 84 has a substantially prismatic shape, and has a predetermined length in the Z direction. In the present modification, the length is slightly shorter than the main body portion 87 in the Z direction. It is also possible to adopt a configuration in which a deformed metal plate is used and the receiving portion 84 and the extending portion 88 are integrally connected as a part of the same metal plate.

  Next, a bracket 33 and a structure for fixing the housing 31b to the bracket 33 will be described with reference to FIGS. 29 and 31, the tray portion 54 of the bracket 33 is omitted for convenience. In FIG. 29, the terminal 32b of the connector 32 is omitted for convenience.

  The bracket 33 has the interposition part 50 and a pair of leaf | plate spring part 51 similarly to the said embodiment. Also in the present embodiment, the leaf spring portion 51 corresponds to the folded portion. The leaf spring portion 51 extends from the both ends of the interposition portion 50 in the Y direction toward the back surface 43c in the X direction, and is folded back with respect to the interposition portion 50 so as to face the interposition portion 50 in the X direction. Specifically, as shown in FIGS. 29 and 30, the leaf spring portion 51 is folded back so as to be substantially parallel to the interposition portion 50. For this reason, the interposition part 50 and the leaf | plate spring part 51 have comprised the substantially U-shape (in other words, substantially C-shape). The leaf spring portion 51 folded back in this way can be spring-deformed in the X direction.

  Further, in the state where the housing 31 b is not disposed, the facing distance between the leaf spring portion 51 and the interposition portion 50 is shorter than the total length of the plate thickness of the lower case 83 and the height of the receiving portion 84. Therefore, the leaf spring portion 51 is in a state in contact with the protruding tip of the receiving portion 84, that is, in a state where the receiving portion 84 is sandwiched between the leaf spring portion 51 and the interposition portion 50, and a broken line arrow in FIGS. As shown, the reaction force by spring deformation (elastic deformation) is applied to the corresponding receiving portion 84. The leaf spring portion 51 is provided to have a predetermined length in the Z direction corresponding to the receiving portion 84. Further, in order to improve assemblability, a protrusion such as a wedge shape or a hemisphere may be provided on the contact surface side of the leaf spring portion 51 as described above. A protrusion such as a wedge shape or a hemispherical shape may be provided on the protruding tip surface of the receiving portion 84. Furthermore, a part of the receiving portion 84 may be tapered so that the protruding height gradually changes so that it can be easily assembled to the bracket 33.

  As shown in FIGS. 28, 29, and 31, the bracket 33 also has a support portion 52. The support portion 52 is provided so as to overlap with the receiving portion 84 in the projection view from the Z direction. Then, a screw (not shown) is inserted through a through hole 53 (not shown) provided in the support portion 52 and screwed into a screw hole (not shown) provided in the receiving portion 84 to support the housing 31b. It is fixed to the part 52.

  According to the configuration described above, it is possible to achieve the same effect as the electronic control device 20 shown in the embodiment. Specifically, the protruding tip with which the leaf spring portion 51 contacts in the receiving portion 84 is a position between the facing surface 43b and the back surface 43c in the X direction. In addition, a pair of leaf springs 51 are provided so as to be elastically deformable in the X direction, and the pair of leaf springs 51 causes the pair of receiving portions 84 located near both ends in the Y direction of the housing 31b to be elastically deformed. A reaction force can be applied. Therefore, the lower case 83 to which the receiving portion 84 is fixed, that is, the casing 31b can be pressed against the interposition portion 50 side in the X direction and fixed to the bracket 33 by the reaction force described above. Furthermore, the electronic control unit 20d can be made thinner in the X direction compared to a structure in which the bracket is screwed to the housing in the X direction and a structure in which the opposite surface and the back surface are sandwiched and fixed by the bracket.

  Thereby, the electronic control unit 20d can be disposed in the narrow space beside the battery 19 in the engine compartment 17 as in the above embodiment. That is, the position of the bonnet 12 can be lowered. Moreover, since the connector 32 is disposed so as to be above the bottom wall portion 40, the lengths of the wire harnesses 22 and 23 can be shortened. In addition, since the leaf | plate spring part 51 contacts the metal receiving part 84, the heat | fever of the 1st circuit board 30a can also be efficiently radiated | emitted to the bracket 33 side via the receiving part 84 and the leaf | plate spring part 51. it can.

  In this modification, the casing 31b has a three-part structure in the X direction, the intermediate case 81 is a resin molded body, and the upper case 82 and the lower case 83 are welded to the intermediate case 81, respectively. . Therefore, it is possible to eliminate the need for a sealing material between the intermediate case 81 and the upper case 82 and between the intermediate case 81 and the lower case 83. Thereby, the housing | casing 31b and by extension, the electronic control apparatus 20d can be made thin in the X direction. In addition, the structure of the metal casing component, that is, the upper case 82 and the lower case 83 in the casing 31b can be simplified.

  Note that the housing 31b is not limited to a three-part structure. For example, the present invention can be applied to the case 31b having a two-part structure. In this case, the receiving portion 84 is provided on one of the two casing constituent members. Further, the position where the receiving portion 84 is provided is not limited to the surface opposite to the facing surface 43 b in the lower case 83. The pair of receiving portions 84 may be provided at a position between the opposing surface 43b and the back surface 43c in the X direction, with the back surface 43c positioned in the Y direction. For example, a stepped portion can be provided on the connecting surface 43d of the housing 31b, and the stepped portion can be used as the receiving portion 84. In this modification, since the receiving portion 84 is disposed away from the intermediate case 81 to which the first circuit board 30a is fixed, the stress acting on the receiving portion 84 due to the holding is caused by the first circuit board. It is difficult to be transmitted to 30a.

  A heat insulating member can be combined with the configuration of this modification.

(Modification 7)
For this modification, reference can be made to the preceding embodiment and the preceding modification. For this reason, the description about the part which is common in the electronic control unit 20 shown in the preceding embodiment or the preceding modification is omitted.

  In the sixth modification, an example in which the pair of leaf spring portions 51 applies a reaction force due to elastic deformation to the corresponding receiving portion 84 has been described. On the other hand, in the electronic control device according to the present modification, the pair of receiving portions 89 applies a reaction force due to elastic deformation to the corresponding folded portion 90. FIG. 32 corresponds to FIG.

  As shown in FIG. 32, in a state where the receiving portion 89 is sandwiched between the interposition portion 50 and the folded portion 90, the pair of receiving portions 89 imparts reaction force due to elastic deformation to the intervening portion 50 and the folded portion 90. It is provided to do. The other configuration is the same as that of the sixth modification. Therefore, also in this modification, the modification shown in the modification 6 can be applied.

  The pair of folded portions 90 basically has the same configuration as the leaf spring portion 51 of the modified example 6 except that the pair of folded portions 90 does not have an elastic deformation function. In other words, the folded portion 90 extends from the both ends of the interposition portion 50 in the Y direction toward the back surface 43c in the X direction and is folded with respect to the interposition portion 50 so as to face the interposition portion 50 in the X direction. Specifically, the folded portion 90 is folded so as to be substantially parallel to the interposition portion 50. For this reason, the interposition part 50 and the folding | returning part 90 have comprised the substantially U shape (in other words, substantially C shape). The facing distance between the folded portion 90 and the interposition portion 50 is a predetermined distance. This facing distance is substantially constant in the Z direction.

  The pair of receiving portions 89 are made by mixing a filler for enhancing thermal conductivity into rubber. As the rubber, for example, silicone rubber can be employed. Silicone rubber is also referred to as silicone rubber. As the filler, metal fillers such as graphite, aluminum, copper and silver, inorganic fillers such as oxides and nitrides such as aluminum oxide, fillers whose surfaces are metal-plated, and the like can be used. Thus, the receiving part 89 is formed using rubber | gum, and has an elastic deformation function.

  The height of the receiving portion 89 in the X direction is set such that the total length of the extending portion 88 and the thickness is longer than the facing distance between the folded portion 90 and the interposition portion 50 in a state before being sandwiched. Has been. For this reason, in a state where the folded portion 90 is in contact with the projecting tip of the receiving portion 89, that is, in a state where the receiving portion 89 is sandwiched between the folded portion 90 and the interposition portion 50, the receiving portion 89 is shown by a broken line arrow in FIG. As shown, the reaction force due to elastic deformation is applied to the corresponding folded portion 90 and the interposition portion 50. In order to improve assemblability, a protrusion such as a wedge shape or a hemispherical shape may be provided on the contact surface side of the folded portion 90. In this case, the facing distance to the interposition part 50 is the distance from the tip of the protrusion. Further, a part of the receiving portion 89 may be tapered so that the protruding height gradually changes so that it can be easily assembled to the bracket 33.

  According to the configuration described above, the same effects as those of the electronic control unit 20d shown in the modification 6 can be obtained. Since the rubber constituting the receiving portion 89 is mixed with a filler for increasing the thermal conductivity, the heat of the first circuit board 30a is transferred to the bracket 33 via the receiving portion 89 and the folded portion 90. It is also possible to efficiently dissipate heat to the side.

  The elastically deformable receiving portion 89 is not limited to one using rubber. A metal spring can also be used. For example, a metal spring may be fixed on the lower case 83, and a contact portion made of, for example, resin may be provided at the protruding tip of the metal spring so that the contact portion contacts the folded portion 90. Further, when the receiving portion 89 is fixed to the support portion 52 by the screw 34, the fixing portion in which the screw hole 44 is formed is made of metal, and the elastic deformation portion of rubber is fixed on the fixing portion. It is good. Further, as shown in the modified example 6, a stepped portion is provided on the connecting surface 43d of the housing 31b, and a member formed using rubber is fixed to the stepped portion so that the member is a receiving portion 89. You can also.

(Other variations)
Although the example in which the housing 31 is disposed beside the short side surface 19c of the battery 19 is shown, the present invention is not limited to this. You may arrange | position beside the long side surface 19b.

  Although the example of the battery 19 was shown as a box-shaped member, it is not limited to this. In addition, it may be employed as long as it has a flat portion at a part of the side surface and is disposed in a compartment separated from the vehicle compartment by the partition wall 16. For example, the engine 18, the relay box 21, the air cleaner, or the like can be a box-shaped member.

  Although the example of the engine compartment 17 in which the engine 18 is arrange | positioned as a compartment and the example of the bonnet 12 was shown as a lid | cover on a compartment, it is not limited to this. A compartment in which the engine 18 is not arranged can also be adopted.
