Abstract

PURPOSE:To prevent the disconnection and deformation of actuators by fixing a wire harness extending from a housing to the housing by a clamp attached to the clamp hole of the housing. CONSTITUTION:A wire harness 184 led to the connection parts of a motor 26 and a base plate is fixed to housings 2 and 2' by a clamp 186 thrust through the clamp hole 185 of the housings 2 and 2'. A wire harness 211 connected to a detecting switch 205 to detect locked or unlocked state by operation of a key is also fixed to the housings 2 and 2' by the clamp 186. Even when tensile loads are applied to the wire harnesses 184 and 211, the loads are shared by the clamp 186, and therefore, damage to the connections with the motor 26 and the base plate is avoided. The occurrence of disconnection and deformation can thus by prevented.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a door lock device.

(Prior art) Conventionally, the actuator for locking and unlocking a door lock is placed on the inside panel of the door, and is equipped with a connector that connects to the wire harness on the vehicle side. Connection work was being carried out through the work hole.

In a structure in which the actuator is arranged in the space below the door rotor installation as in the present application, if the actuator is equipped with a connector, it is not possible to visually connect it through the door inner panel work hole, and the wire harness must be extended from the actinator. It is necessary to place a connector near the hole.

(Problem to be solved by the present invention) In the work of extending the wire harness and connecting it to the vehicle side connector, the wire harness on the actuator side has to be pulled and connected, and the motor, switch, etc. The above-mentioned tensile force causes problems such as permanent deformation and wire breakage at the connecting points where the wires are connected with solder or the like, impairing the reliability and functionality of the actuator.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention basically fixes a wire harness extending from the housing to the housing with a clamp attached to a clamp hole drilled in the housing. Adopt means to do so.

(Function) In the present application, the wire harness that comes out from the actuator is fixed to the housing body by a clamp that passes through a clamp hole provided in the housing body, and even if a tensile force is applied to the connector at the tip of the wire harness,
This clamp part locks the motor inside the actuator.
No tension is applied to the connection points connected to the switch, etc., and therefore, disconnection, deformation, etc. inside the actuator can be prevented, and reliability can be improved.

In addition, although the distance to the working hole differs depending on the vehicle, this can be accommodated by changing the length of the actuator's wire harness, increasing the generality of the entire door lock device, and creating an inexpensive actuator with good productivity. can be obtained.

(Example) An example in which the concept of this example is applied to a door lock device will be described below. The door lock device ill has an abbreviated release lever 3 pivotally supported by a main housing 2 made of synthetic resin.

This release lever 3 is rotatable around a fulcrum 26 at its center.

This fulcrum 26 is also the center of rotation of a pawl of a door lock actuating unit including a ratchet and pawl (not shown), and the release lever 3 is interlocked with the pawl via a pin 27. When the door is closed, the above-mentioned pawl engages with a latch provided on the door lock operating portion that engages with a striker attached to the vehicle (not shown). The position of the release lever 3 shown in Figure 1 is a state in which the aforementioned latch of the door lock and the pawl are engaged, and by rotating this lever 3 counterclockwise, the pawl rotates the ratchet and the aforementioned latch and pawl are engaged. A latch release state is obtained in which the mesh is disengaged, and the door can be opened. When the outside handle is operated, a force is applied in the direction indicated by 29, and the rod 4 rotates the lever 30, which is pivotally supported on the main housing 2, counterclockwise about the fulcrum 31. Also, when the inside handle is operated, a force is applied in the direction shown by 28, and lever 3
0 in the counterclockwise direction around the fulcrum 31.

The counterclockwise rotation of the lever 30 pushes down the open lever 5 pivotally attached to one end of the lever 30. This downward movement of the open lever 5 is caused by the protruding piece 6 at the center of the open lever 5 pushing the release lever 3 117, rotating the release lever 3 counterclockwise around the fulcrum 31, and locking the door. to the latch release state and enable door opening (see Figure 2).

To prevent the door from being opened inadvertently while the vehicle is running,
To lock the door, generally use locking button 8
The door is locked by pressing and rotating the locking arm 9 clockwise. A portion of the locking arm 9 is connected to the lower part of the open lever 5 via a long length. Locking arm 9 is the first
When in the position shown, the lowering of the open lever 5 allows its protrusion 6 to come into contact with the end 7 of the release lever 3.

However, when the locking button 8 is pressed and the locking arm 9 is rotated clockwise around the pin 10 together with the pin, the open lever 5 moves in the direction of arrow C, and the protrusion 6 is moved to the end 7 of the release lever 3. (See Figure 3). As a result, the handle is operated to open the lever. (See Figure 4).

The keyless rotor mechanism will be explained. With the door open, press the locking button 8, rotate the locking arm 9 clockwise, and push the protrusion 6 into the release lever 3.
The end portion 7 of the When the outside or inside handle is operated, the open lever 5 is pushed down, resulting in the state shown in FIG. 5. When the door is closed in this state, the release lever 3 is rotated counterclockwise, but the step 11 of the open lever 5 and the protrusion 12 of the release lever 3
The release lever 3 is free to rotate counterclockwise, and the door is kept locked. (
(See Figure 6). After the door is closed, the release lever 3 is brought into the state shown in FIG. 5 by the spring of the door lock operating section, and returns to the state shown in FIG. 3 when the handle is no longer operated.

Next, the self-cancelling mechanism will be described. With the door open, press the locking button 8, rotate the locking arm 9 clockwise, and rotate the open lever 5 in the direction C shown in Figure 1 to return to the state shown in Figure 7. do. When the door is closed without operating the outside or inside handle, the release lever 3 is rotated counterclockwise by a pole of a door rotor actuating section (not shown). This movement causes the protruding piece 12 of the release lever 3 to come into contact with the stepped portion 11 of the open lever 5, causing the open lever 5 to
Rotate it clockwise as shown in FIG. As a result,
The locking button 8 is returned to its original position and the locking arm 9 is rotated counterclockwise around the bottle 10 via the length of the open lever 5. That is, the state returns to the state shown in FIG. 1, so when the handle is operated to open the door, the protrusion 6 of the open lever 5 pushes down the end 7 of the release lever 3, and the lever that enables the door to open is pressed down. Set to locked state.

Key operations will be described with reference to FIG.

A key operation lever 13 is rotatably supported by the housing 2', and its protrusion 14 is arranged in parallel with the protrusion 15 of the locking arm 9. This lever 13 is connected at one end to a key cylinder via a rond. When the key is operated in the locking direction, the key operation lever 13 rotates clockwise from position A to position B, and the locking arm 9 is rotated clockwise due to the contact between the protrusions 14 and 15. When the locked state of the door lock is secured and the key operation is stopped, the key operation lever 13 returns from position B to position A by the action of a spring attached to the key cylinder side. That is, the locking button 8 is pressed down, in other words, the open lever 5
The protruding piece 6 and the end 7 of the release lever 3 are not opposed to each other, and even if the outside or inside handle is operated, the door remains closed. When the key is rotated in the unlocking direction, the stepped portion 14' pushes against the protrusion 15, and the locking arm 9 is rotated counterclockwise to the unlocked state shown in FIG. In the state shown in FIG. 1, even if the key operation lever 13 is rotated to the position B' using the key, the stepped portion 14' will only approach the protrusion 15, and the locking arm 9 will not rotate. There isn't.

In addition to the above-mentioned manual operation, the bin 10 is electrically rotated in response to an instruction signal from the driver, and the locking arm 9 is rotated clockwise (or vice versa) to obtain a locked and afro-lockable state. Things will be done. See FIG. 9. An operating lever 17 having an arm portion 16 is fixed to the bottle 10. Both ends 19 and 20 of the pair of raised protrusions of the wheel gear 18 rotatably supported by the housing are opposed to the downward arm 16 at the tip of the operating lever 17.

On the other hand, an annular groove 21 is provided in the bottom plate portion of the sub-housing 2'. As shown in FIG. 10, this groove 21 is partially narrowed by opposing wall surfaces 22 and 23. Put the coil spring 24 into the groove 21, and attach the end of the coil spring 24 to the wall surface 2.
2. Place it in contact with 23's shoulder. Furthermore, wheel gear 1
A projecting piece 25 protruding from the lower surface of the wall 8 is positioned between the wall surfaces 22 and 23. As a result, for example, when the wheel gear 18 rotates clockwise as seen in FIG. 10, the protrusion 25 compresses the spring 24 while pushing the right end of the spring 24. At this time, the left end of the spring 24 abuts against the shoulder of the wall surface 22.23, allowing the spring 24 to be compressed. This rotation of the wheel gear 18 causes the end 19 of the convex portion 45 to come into contact with the arm portion 16, causing the operating lever 17 and the bin 10 to rotate, allowing the locking arm 9 to move from position A to position B. Make it. When the wheel gear 18 is rotated in the opposite direction, the protrusion 25 compresses the spring 24 counterclockwise while bringing the right end of the spring 24 into contact with the shoulder of the wall surface 22.23, and the end 20 causes the actuation lever 17 to and rotates the bin 10 to move the locking arm 9 from the B position to the A position. The use of such an annular groove 21 allows the spring 24
It has a long overall length to ensure sufficient flexibility.

The wheel gear 18 rotatably supported by the housing meshes with the worm gear 27 directly connected to the electric motor 26, and the wheel gear 18 is rotated by controlling the power supply to the motor 26.
The direction of rotation is controlled.

Generally, when the advance angle T0 of the worm gear becomes larger than the friction angle φ, rotational torque can be transmitted from the wheel gear 18 to the worm gear 27. Therefore, in this example, μ
Using the relationship of (friction coefficient) = tan φ, the advance angle is set to be equal to or greater than the friction angle (φ = 8.53°). That is,
Friction coefficient μ between phosphor bronze worm gear 27 and resin wheel gear 18 = 0.1 to 0.15, friction angle φ = 5.
71° to 8.53°, and the friction angle is set to 8.53° or more to enable rotation of the worm gear 27 from the wheel gear 18. The lead angle (γ
. ) is selected by the driver, for example, when the electric motor 16
Even if the wheel gear 18 is rotated by a door lock operation using a door lock, the spring 24 allows the wheel gear 18 to be returned to its original position immediately after the operation, thereby enabling subsequent manual operation. In other words, it enables manual and then electric operation, or electric and then manual operation. In addition, since the operating lever 17 and the wheel gear 18 are completely separated during manual operation, the arm portion 16 only runs idle between the pair of ends 19 and 20 of the convex portion 45, and is unable to pull the motor portion. It is easy to operate and has a good operating feel.

As shown in FIG. 12, the motor 26 inside the sub-housing 2'
The pin IO, which is fixed to the actuating lever 17 and is actuated by the pin IO, has a useful part and a square part at its tip, and is inserted into the stepped hole 32 of the housing 2'. The outer peripheral surface of the stepped hole 32 serves as a bearing portion 34 that receives the hole 33 of the key operation lever 13 on its outer peripheral surface. The square portion 9 of the pin IO that protrudes from the bearing portion 34 when the pin 10 is inserted into the bearing portion 34 is seated on the top surface of the bearing portion 340 . Since the bearing part 34 for the key operation lever 13 is formed integrally with the housing 2, a separate bearing is not required, and the mounting part of the locking arm 9 does not protrude outward.

Each end of the turnover spring 36 that holds the locking arm 9 in the locked and unlocked positions is
As shown in the figure, it is engaged with a recess 37 of the housing 2 near the bearing portion 340 and a hole 38 of the locking arm 9 which is opposite to the recess 37. In this example, since the pin 10 is directly connected to the locking arm 9, the rotational force from the motor is efficiently transmitted to the turnover spring, so that the operating force can be small. This means that motor 2
6, making it possible to downsize the entire device.

As already understood from the explanation of FIG. 1, the fulcrum 26, which is the center of rotation of the release lever 3, also serves as the center of rotation of the pawl of the door lock operating section (not shown), and the pin 27, which can freely come into contact with the pawl, supports the pawl. The door lock operating section is thus housed within the housing 2, as shown in FIG. The various levers and arms described above are arranged on the outer surface of the housing 2. On the other hand, pin 1 serves as the output shaft including the motor 26, etc.
The actuator for rotating the door lock is housed in the extension of the housing 2 for the door lock actuator. Furthermore, compared to a system in which the motor 26 and the wheel gear 18 are arranged in parallel and the driving force is transmitted to the output shaft 10 via a speed reduction mechanism such as a spur gear, the electric motor 26 rotates the operating lever 17. The locking arm 9 is moved to the locked position (B) and unlocked position (B') shown in FIG.
Stoppers 39 for stopping the operating lever 17 are arranged at these positions (B, B'). The function of this stopper 39 is
This will be explained with reference to FIG. Although FIG. 14 shows only one stopper 39, the function of the other stopper is the same, so the drawing and explanation thereof will be omitted.

The operation of the electric motor 26 causes the wheel gear 18 to rotate via the worm 27, and the actuation lever 17 to be rotated together with the pin 10 by the end 19 of the convex portion 45. At this time, the return spring 24 is bent and stores energy for returning the wheel gear 18 to the neutral position. In this example, when the actuating lever 17 reaches the normal stop position 40, the actuating lever 17 and the stopper 39 come into contact and attempt to prevent the actuating lever 17 from moving, but the rotational inertia of the motor causes the stopper 39 to The operating lever 17 moves to the overtravel position 41 while being elastically deformed.

That is, the stopper 39 is elastically deformed by the amount of overtravel. The stopper 39 is made of a solid or hollow body such as rubber or synthetic resin that allows such elastic deformation. It serves to push the operating lever 17 back to the normal locking and unlocking positions together with the spring 24. The auxiliary force from the stopper 39 can reduce the auxiliary force of the spring 24 and the output of the electric motor 26 accordingly. Incidentally, the relationship between the wheel gear 18 and the motor reverse rotation torque is shown in FIG.

Although the relationship between the pin 10 and the housing 2 is shown in FIG. 12, it will be explained in more detail using FIG. 16.

The pin 10, which is an output shaft fixed to the operating lever 17, has a stepped structure consisting of a large shaft diameter portion 40 and a small shaft diameter portion 41. On the other hand, the hole 32 of the housing 2' has a large opening 42 for receiving the large shaft diameter part 40 and a small shaft diameter part 41.
It consists of a small opening 43 that receives the opening. Housing 2'
The locking arm 9 is fixed to the smaller shaft diameter portion 41 that protrudes further, and the key operation lever 13 is rotatably supported by the bearing portion 34 of the housing 2'.

When installing the pin 10 into the hole 32 of the housing 2', fit the O-ring 44 into the small shaft diameter part 41 of the pin 10, and insert it from the inside of the housing 2' so that the small shaft diameter part 41 protrudes from the housing 2'. Insert the output shaft lO into the hole 32. The output shaft 10 is inserted into the hole 32 using the O-ring 44.
The stepped portion of the hole 32 is opposed to the stepped portion of the pin 10 via the hole 32.

In this way, movement of the pin 10 relative to the housing 2' can be restricted. This is useful to ensure correct movement of the actuation lever 17.

Further, since the O-ring 44 can be attached to the pin 10 by simply attaching it to the hole 32 of the housing 2', the assembly work is extremely easy.

In the illustrated example, in order to rotate the operating lever 17, the first
As shown in 6.17ffl, the wheel 18 is provided with a semicircular arc-shaped rising portion 45, but instead of this, a pair of pins may be installed on the wheel 18. End 1 of convex portion 45
9.20 can come into contact with the arm 16 of the operating lever 17. When the electric motor 26 is energized, the wheel 18 rotates via the worm 27. Depending on the rotational direction of the wheel gear 18, one end of the convex portion 45 comes into contact with the arm 16, and while compressing the return spring 24, the operating lever 17
is moved to the lock or unlock position, and the pin 10 serving as the output shaft moves the link mechanism. When the operating lever 17 is in the locked or unlocked position and the motor 26 is de-energized, the releasing force of the compressed return spring 24 is applied to the wheel 18, the worm 27 and the motor 2.
6 and return the wheel 18 to the neutral position. When the wheel 18 returns to the neutral position, a gap 46 is left between the end of the convex portion 45 and the arm 16, as shown in FIG. This gap 46 allows the rotation speed of the electric motor 26 to be immediately rated when the electric motor 26 is energized. Increases static friction in locking mechanisms, etc. That is, the convex portion 45 is connected to the operating lever 17.
When it comes into contact with the arm 16 of the motor, the rotational inertia energy of the motor can be transmitted to the arm 16, thereby making it possible to downsize the motor.

Having described the door lock device 1, the mounting portion of the door lock device 1 will be explained with reference to FIG. 18. The vehicle has a center pillar 49 between the front door 47 and the rear door 48;
A hinge 50 and a striker 51 for the rear door 48 are fixed to. The striker 51 can be freely engaged with and disengaged from a ratchet (not shown) of the door lock device 10 when the front door 47 is opened or closed. On the other hand, when the windshield 52 of the front door 47 moves up and down, it follows a trajectory 5 along the center pillar 49.
Move along 3. Therefore, the door lock device 1 fixed to the front door 47 side avoids the trajectory 53 of the windshield 52, and the door lock device 1
It is necessary to prevent interference with In order to avoid such interference, a concave portion 54 is formed on the front edge of the center pillar 49 and an overhang 55 is formed on the rear edge of the front door 47, and the door is inserted into the overhang 55. Lock device 1
to be stored. That is, the door lock device l is connected to this projecting portion 5.
It is necessary to have an external shape that fits within the limited space of 5. Note that the shapes of the projecting portion 55 and the concave portion 54 are designed so as not to interfere with the lower hinge 50 of the rear door 48. In this example, the rear edge of the front door 47 has a shape shown at 113.

As is clear from FIG. 16, in this example, the lower part of the main housing 2 is extended and the electric actuator is disposed in this extension, so the actuator is supported by the sub-housing 2', and this sub-housing 2' is used as the main housing. It is fixed to the housing 2. The main housing 2, which is housed in the above-mentioned limited space overhang 55, has a lower portion extending forward.

See FIG. 19. A mating surface 115 of the sub-housing 2' that is mated to the main housing 2 whose lower portion is bent forward is formed in a straight line inclined to the mounting surface 116 of the door lock device 1 in order to improve the sealing performance therebetween. In order to further improve the sealing performance of both housings 2.2', that is, to prevent the mating surfaces 115 of both housings 2.2' from shifting, a pair of hooks 117 are provided at the bottom of the sub-housing 2', as shown in FIG. are provided, and this pair of hooks 117 are brought into contact with the lower end surface of the main housing 2. The contact of the hook 117 with the lower end surface of the main housing 2 (see FIG. 20) prevents displacement when the two housings 2.2' are fastened, improving sealing performance, and furthermore, the contact between the pin 10, which is the output shaft, and the The pin receiver of the housing 2 prevents misalignment with the hole.

Referring again to FIG. A substantially U-shaped groove 118 is arranged along the inner edge of the main housing 2, and a rubber O-ring 119 is inserted into this groove 118. Flex it to ensure sealing pressure. The inner edge of the main housing 2 has a wall 120 extending upward, and even if rainwater or dust passes through the O-ring 119, this wall 120 prevents the rainwater or dust from entering into the housing 2. . This wall 120 is
It is also effective to improve sealing performance when the mating surfaces of both housings 2.2' are bonded or welded.

As mentioned above, the housing has a substantially doglegged shape with the lower part protruding toward the front of the vehicle, so that the actuating lever 17 is attached to the shaft portion 121 fixed to the output shaft 10, as shown in FIG.
It extends to the left side of the paper and indicates the locked or unlocked state
A stepped portion 125 is provided which connects an arm portion 124, which holds a contact 123 to be detected in cooperation with a substrate 122 fixed to the housing 2, and an arm portion 16, which is arranged to avoid interference with the lower shape of the housing. Be prepared.

A ring-shaped convex portion 126 is formed on the side of the shaft portion 121 that contacts the bearing surface of the housing 2', which facilitates dimension control in the thrust direction, reduces the contact surface with the housing 2', and reduces rotational resistance. Grease retention 12
7 is formed.

Further, the arm portion 16 is slidably supported by a convex portion 128 provided on the housing 2, thereby preventing an increase in rotational resistance due to full rotation of the arm portion and the housing.

The aforementioned contact 123 is connected to the arm portion 124 of the operating lever 17.
It consists of a fixed part that is attached to the protrusion 129, 129' and a contact part 130, 130' that slides on the board 122, and the fixed part has a locking part that prevents the arm from being removed from the protrusion. 131 is equipped.

FIG. 21 shows the operating state of the switch section.

The board 122 is made of an insulator such as epoxy resin,
Conductive parts 131 and 131' made of copper or the like are arranged in the passage parts of the aforementioned contact parts 130 and 130'.

In the embodiment, the conductive portions 131.131' are the contact portions 130.131'.
130' and the detection circuit is open, it is set as an unlocked state, and when it is closed, it is set as a locked state.

In this way, since the switch part is arranged on the operating lever 17 that is directly connected to the locking lever 9 that switches between locking and unlocking, the accuracy of nine position detection is improved. Since the arm part 124 of the lever 17 is arranged to avoid overlapping with the protrusion 129 that fixes the contact 123, the board and the arm part can be brought as close as possible, and the height of the drive part can be reduced.

Please refer to FIGS. 22 and 23. When a seal 189 made of rubber or the like is attached to the door panel 187 with a clip 188 and seals between the door and the body and is arranged to pass over the actuator part of the door lock, the tip 190 of the clip 188 described above Interference is a problem.

In this embodiment, attention is paid to the empty space created above the motor housing portion of the housing 2, and a recess 191 is provided as depressed as possible to ensure a gap between the recess 191 and the tip 190 of the clip 188.

In the acticoator part shaped like this,
Furthermore, by providing a recess to avoid interference with the tip of the clip, it is possible to reduce the substantial space required between the door panel 113 and the door glass elevation trajectory 114 shown in FIG. A compact door lock with a high degree of freedom can be obtained.

In the embodiment shown in FIG. 22, the housings 2 and 2' are fastened together by a screw 192.

As shown in FIGS. 17, 24, and 25, a screw 192 passes through the housing 2'. 1.19
The housing 2 is provided with a fastening hole 194 that is slightly smaller than the outer diameter of the screw 192.

Refer to FIG. 26. By fastening housings 2 and 2'
In order to prevent the relationship from shifting, the hole in the housing 2' arranged diagonally is a hole 195 that is slightly smaller than the outer diameter of the screw 192, so that when the screw 192 is tightened, the center of the screw shaft and the hole are automatically aligned. It takes a structure where the center matches.

In this way, with the centering structure that is inexpensive and does not take up space, the pin 10 that occurs due to misalignment between the housings 2 and 2'
The output loss at the bearing part can be reduced, and the motor output can also be reduced, making it possible to downsize the motor and achieve smooth and quiet operation.

Please refer to FIGS. 17, 24, and 27.

In order to prevent the stopper 39 held by the stopper holding portion 196 of the housing 2 from coming out, the stopper 3 of the housing 2' is
A removal stop 197 is provided at a position opposite to 9.

In this way, by providing the removal stop 197゛, the lock,
At the unloading position, an impact load including the rotational inertia load of the motor is applied to the stopper 39 via the operating lever, causing elastic deformation, and even if the stopper 39 attempts to pull out from the stopper holding portion 196, the pullout is prevented by the stopper 197. Therefore, the retention of the stopper 39 can be guaranteed even under repeated loads, and stable performance can be maintained over a long period of time.

Further, since the stopper part is housed between the housings 2 and 2', the performance of the stopper rubber is not deteriorated due to the adhesion of foreign matter such as rainwater and clumps, and the durability is excellent.

Air venting inside the housing will be described with reference to FIGS. 16 and 28. The lower end of the housing 2 (on the left side of the paper) is provided with an air hole 107 formed in cooperation with the housing 2'. This prevents rainwater, etc. adhering to the interior from being sucked into the interior.

The shape of the air hole 107 is similar to that of the wall 10 facing the opening 108.
9 is provided, the air hole is formed into a substantially U-shape by the wall 109 and the opposing wall 110, and the size of the hole is as follows.
The side walls 111 and 112 form a substantially rectangular shape.

Therefore, even if water droplets such as rainwater adhere to the vicinity of the opening 108 or there are lumps or the like, the two walls 109 and 110 prevent them from entering the housing 2.

Draining water from the housing will be explained with reference to FIGS. 16 and 29.

A space 179 created between the plate 178 of the door lock that comes into contact with the door lock mounting surface 116 of the door panel and the housing 2 houses a well-known engagement mechanism for keeping the door in the closed state of the door lock. .

A groove 180 formed between the groove 179 and the plate 178 is provided in the lower part of the space 179 to drain water such as rainwater, and extends as far as possible below the plate 178.

At the bottom of the groove 180, the bearing of the bottle 10 is placed in the water channel 182 with the portion 181 as close to the door panel 113 as possible.
is formed, and the groove 180 is substantially terminated by a wall 183.

In this way, by providing the wall 183 that limits the groove 180, the thickness of the door rotor acticoator part in the longitudinal direction of the vehicle can be reduced, and the gap between the door glass's vertical path 114 can be secured, and the door lock device can be It can be placed higher up on the door to improve the strength of the upper part of the door against collisions, or it can be placed at the rear of the door from the vertical path, increasing the door glass area and increasing design freedom. It can be increased.

Referring again to FIG. 16, the area around the shaft 100 will be explained.

The wheel gear 18 is rotatably connected to a shaft 100 inserted into the housing 2', and its movement in the removal direction is restricted by a washer 101 caulked to the tip of the shaft 100.

A washer 102 is inserted between the wheel gear 18 and the housing 2' to reduce resistance during rotation and prevent the resins from coming into contact with each other.

A ring-shaped convex portion 103 is formed on the contact surface of the wheel gear 18 with the washer 101, which facilitates dimension control in the thrust direction, reduces the contact area with the washer 101, and reduces rotational resistance. A grease reservoir 104 is formed.

The portion of the shaft 100 that is inserted into the housing 2' has a structure that increases the strength against bending and rotation of the shaft 100 that occurs when the worm gear 27 and the wheel gear 18 engage with each other.
In addition, in order to improve the holding strength in the thrust direction and to serve as a catch when the tip of the shaft 100 and the washer 101 are caulked, the other end 105 protrudes outward from the surface of the housing 2', so that rainwater etc. can escape from the gap. A collar 106 is provided to lengthen the insertion path and prevent rainwater from entering.

FIG. 17 is a view from inside the housing 2',
The positional relationship between the pin 101 operating lever 17, the wheel gear 18, the motor 26, and the worm gear 27 is shown, and as is clear from FIG. The worm gear 27 and the motor 26 are supported by supports 132, 133, 134 provided in the housing 2'.
The rotational movement of the motor itself is supported by the wall 1
35.136.

In this way, the positional relationship of the drive transmission system, especially the wheel gear 1
Since the meshing relationship between the worm gear 27 and the worm gear 27 is determined only by the sub housing 2', manufacturing errors such as gear pitch distance can be minimized, smooth power transmission is possible, and the motor outlet This will lead to a shift towards public affairs, which will reduce losses.

The motor support structure will be explained in detail in FIG. 30.

A case 137 made of a steel plate and formed by deep drawing is fixed to a case 138 made of resin or the like by claws 139.

The motor shaft 140 has a bearing 141 fixed to the bearing part 137' of the case 137 by press fitting or the like, and a bearing part 1 of the case 138.
It is rotatably supported by a bearing 142 fixed to 38' by press fitting or the like.

The motor shaft 140 includes a commutator section 143 that receives electricity from the outside and a core 145 that holds a winding 144.
is fixed.

Further, in order to prevent interference between the winding 144 and the case 137, a collar 146 is disposed between the core 145 and the winding 144.

Magnet) 14g is fixed to the case 137.

One end 147 of the motor shaft is machined into a spherical shape, and is supported by a metal thrust plate 149 disposed between it and the resin case 138.

This thrust plate 149 is connected to the other end 150 of the motor shaft.
It resists the load when the worm gear 27 is firmly fixed to the knurl 151 provided in the housing, and prevents cracking of the resin case 138. It also resists the thrust load generated during locking and unlocking operations, and improves durability. It is effective for

The bearing of the case 137 is the support part 13 that supports the part 137'.
3 and the support part 1 that supports the bearing part 138' of the case 138.
32 determines the thrust direction position of the motor and its positional relationship with the shaft 100 that pivotally supports the wheel gear 18.

Next, a description will be given of the support portion 134 that supports the shaft portion 152 of the worm gear 27 whose tip is machined into a spherical shape.

The motor shaft 140 is movable in the thrust direction by a gap 153 provided between the collar 146 and the bearing 141.

In addition, when a load is applied to the motor shaft 140 in the direction of entering the motor case side, and when one end 147 of the motor shaft contacts the thrust plate 149 and rotates, the rotational resistance is small because of the contact with the spherical surface, and the motor shaft rotates with a light torque. can do.

Conversely, if a load is applied in the direction of pulling out the motor shaft, the end face of the collar 146 and the end face of the bearing 141 come into contact, resulting in large rotational resistance and a large torque being required to rotate the motor shaft.

As shown in the example, in worm meshing, a load is applied in either the forward or reverse direction to push in or pull out the shaft, and the motor output needs to be large enough to account for the large rotational resistance mentioned above. Become.

Furthermore, if the motor is de-energized after being driven, the wheel gear 18 is driven by the return spring 24, and the worm gear 27 is rotated while returning to the neutral position. , the output of the return spring must also be increased, and the output of the motor must be increased accordingly. In this way, in order to prevent contact between the collar 146 and the bearing 141, which would cause various output losses, the shaft portion 152 of the worm gear 27 has a spherical tip.
and the support part 134 to absorb manufacturing errors between the motor shaft length 154 and the length 155 to the surface of the thrust load bearing of the support part 134, and to reduce the gap between the collar 146 and the end face of the bearing 141. Gap smaller than 153 Gap 156
is set.

Therefore, even if the motor shaft 140 moves in the direction in which it is pulled out from the case, the spherical tip of the shaft portion 152 of the worm gear 27 comes into contact with the support portion 134, and the collar 146
Contact between the end faces of the bearing 141 and the bearing 141 can be avoided, an increase in rotational resistance can be prevented, loss of motor output can be prevented, and the motor can be made smaller.

The manufacturing error between the support parts 132 and 133 is
The direction is set in such a direction that there is a gap with the motor case to compensate for the amount that cannot be absorbed by elastic deformation of the case 138, and when the motor is assembled, the case 138 and the support part 132 are brought into contact with each other.

In addition, in the radial direction of the shaft portion 152 of the worm gear 27, a small gap is set between the supporting portion 134 and the operating lever. When the distance is about to increase, it will come into contact with you.

When the power to the motor is cut off and the return spring 24 drives the wheel gear 18 and rotates the worm gear 27 to return to the neutral position, the support part 134 and the shaft part 15
2, since the contact is released, there is no loss of return spring force in this part, and therefore the return spring force can be reduced, and the motor can be made smaller. Further, since the support parts 132 and 133 determine the normal motor shaft, manufacturing errors can be easily absorbed, and an inexpensive housing can be obtained.

Next, the housing 2 is provided with the following support parts. That is, as shown in FIG. 31, the tip 1 of the worm gear
A support portion 157 is provided that comes into contact when the portion 52 is displaced.

As shown in FIG. 32, motor case 1370 bearing part 13
A support portion 158 is provided to support 7'.

As shown in FIG. 33, an elastic body 159 such as a sponge is arranged in a bent manner on the housing 2 side of the motor case 137 supported by the housing 2'. If the dimension 160 between the support parts 132 and 133 is made large and a gap is created between the support parts 132 and 133 and the motor case, the opening/closing of the door, vibration during driving, or motor drive This prevents the motor case from moving due to worm engagement reaction force, etc., and causing abnormal noise.

As shown in FIG. 34, the motor case 1380 and the bearing part 138
A support portion 161 is provided to support .

Next, the meshing between the worm gear 27 fixed to the motor shaft 140 and the wheel gear 18 that meshes with this gear will be explained.

FIG. 35 shows the standard meshing state of the worm gear 27 and the wheel gear 18, 162 is the tooth of the wheel gear, 1
63 indicates teeth of the worm gear, and 164 indicates backlash at standard time. The shape of the wheel gear 18 is 16.1.
As shown in Figure 7, it has a complicated shape and is therefore made of resin. For products with such complex shapes and indeterminate wall thickness, distortion of the external shape due to molding is unavoidable, and if the face width increases, backlash will decrease, making it impossible for smooth tooth meshing operation, and also causing sink marks. If this occurs, a load will be applied to the tooth tips, resulting in a decrease in strength.

Generally, to increase backlash, a method of setting the pitch distance larger than the standard value, as shown in Fig. 36, is used, but a reduction gear using small gears, for example, a module 0.6 (tooth depth 1.35 aua) In this case, the pitch distance can only be increased by a small amount, and the required amount of backlash cannot be obtained. In addition, more load will be applied to the tooth tips,
In particular, in the case of a lever that drives a lever or the like that is restricted in operation by coming into contact with a fixed object after a predetermined operation, when the stove is used, the motor rotation is abruptly stopped, so an impact load containing the rotational inertia energy of the motor is applied. The tooth itself will be damaged.

In the present embodiment shown in FIG. 37, the tooth profile and pitch distance of the resin wheel gear 18 are standard, and the teeth of the phosphor bronze worm gear 27, which has relatively sufficient strength, are transposed sideways to prevent backlash. increase. Reference numeral 165 indicates a worm gear tooth whose tooth width has become smaller due to lateral dislocation, and 166 indicates backlash that has increased due to lateral dislocation. Like this,
Since the distance between the pitches is standard, contact at the tips of the teeth can be prevented, there is no loss in strength, and strain on the teeth of the wheel gear can be absorbed.

Next, the relationship between the tooth line direction and the actuation lever will be explained in detail.

FIG. 38 shows the protrusion 45 of the wheel gear 18 and the actuating lever 1 that are engaged with the worm gear 27 due to the drive of the motor.
7 comes into contact with the arm 16, and the lever 17 comes into contact with the stopper 39.
The state shown is that it has moved to the unlocked position where it comes into contact with. Third
FIG. 9 similarly shows a state in which it has been moved to the lock position.

In FIG. 38, an arrow 167 indicates the driving force applied from the worm gear 27 to the wheel gear 18.

An arrow 168 indicates a reaction force from the stopper 39 to the actuating lever 17, and an arrow 169 indicates a reaction force from the arm 16 to the end of the convex portion 45. FIG. 40 is a view from H in FIG. 38, and the wheel gear 18 is provided with teeth 170 facing upward to the right in the paper.

The driving force 167 given by the worm gear 27 generates a component force 171 directed upward in the plane of the paper due to the inclination of the teeth 170 in the case of a tooth line as shown. FIG. 41 is the J parent diagram of FIG. 38, and the component force 171 described above elastically deforms the resin wheel gear in the direction of shallower meshing with the worm gear, counterclockwise in the plane of the paper, and Although the insert portion is elastically deformed, the reaction force 169 acting on the convex portion 45 that generates a resistance force in the clockwise direction on the paper prevents the engagement between the wheel gear and the worm gear from becoming shallow.

In FIG. 39, 172 indicates the driving force given to the wheel gear 18 by the worm gear 27, 173 indicates the reaction force from the stopper 39 to the actuating lever 17, and 174 indicates the arm 1.
6 shows the reaction force to the convex portion 45.

FIG. 4°2 is a parent diagram of FIG. 39, and the driving force 172 given by the worm gear 27 generates a component force 175 directed downward in the plane of the paper.

FIG. 43 is the L parent diagram of FIG. 39, and the aforementioned component force 175
The wheel gear or the insert portion of the shaft 100 is elastically deformed in the direction of deeper engagement with the worm gear, that is, in the clockwise direction in the drawing.

When the actuating lever 17 is stopped by the stopper 39, the contact point between the protrusion 45 of the wheel gear 18 and the arm 16 is located near the line connecting the worm gear 27 and the shaft 100, so the reaction force 174 causes the engagement to occur. No effective drag is generated to prevent shallowing. However, due to the action of the component force 175 described above, shallow engagement is prevented.

Figures 44 and 45 show tooth 17 on the upper left side of the paper.
6 is shown. The driving force 172 provided by the worm gear 27 generates a component force 177 directed upward in the plane of the paper. This upward component force causes the meshing relationship between the worm gear and the wheel gear to become shallow, but the reaction force 174 acting on the convex portion 45 as described above is effective in preventing the meshing from becoming shallow. Since no drag is generated, for example, the tips of the teeth of a resin wheel gear may be lost, or the tips of the gears may run over each other and become immobile.

As in the embodiment shown in FIG. 40.42, the actuating lever 17
If the stopper position is located near the line connecting the worm gear 27 and the shaft 100, and the contact point between the protrusion 45 of the wheel gear 18 and the arm 16 is located, the meshing will occur due to the component force generated by the driving force from the worm gear. By determining the tooth line in a direction that does not make it shallow, you can gain freedom in the arrangement of operating levers, wheel gears, worm gears, etc.
A compact power actuator section for the door rotor can be realized.

FIG. 46 shows the protrusion 45 of the wheel gear 18 and the arm 16.
An embodiment is shown in which a cam surface is provided between the shaft and the lever to improve the lever ratio and increase the output of the output shaft 10.

The working relationship between the protrusion 45 and the arm 16 has been described in FIG. It is preferable that the contact point of the arm 16 with the convex portion 45 be located as far away from the rotation center of the lever 17 as possible. The taper of the convex portion 45 of the wheel gear 18 that runs idly between the gap 46 makes contact with the rounded tip 225 and the substantially V-shaped cam surface 226 that widens toward the tip of the arm 16. come into contact with The substantially V-shaped cam surface 226 of the arm 16 is effective in arranging the contact point of the tip 25 of the convex portion 45 as far away from the center of rotation of the lever 17 as possible.

The substantially V-shaped cam surface 226 changes from the middle to a cam surface 227 that is formed thinner toward the tip. Cam surface 2
27 and the tip 225 begin to come into contact with each other at approximately the middle position of the operation of the lever 17, and gradually change to contact with the cam surface 228 formed continuously with the tip 225, and the arm 17 At the stop position where the arm 16 is stopped by the stopper 39, the cam surface 228 and the cam surface 227 of the arm 16 are in complete contact.

In this way, at the stop position where a large impact load including motor rotational inertia acts, the large cam surface 228 is brought into contact with the tip 225 to prevent wear and deformation of the tip 225.
It is possible to obtain stable performance over a long period of time.

Next, a gap 230 is set between the extension portion 229 of the arm 16 extending toward the rotation center of the lever 17 and the tip portion 225, and on the rotation trajectory of the lever 17, It is arranged so as to interfere with the aforementioned extension portion 229 and tip portion 225 .

During manual locking and unlocking, the arm 16 of the lever 17 runs idly between the tips 2250 of the convex portions 45 mentioned above.

At the locked and unlocked positions, the stopper 39 is elastically deformed by further load in the direction of activation, the gap 230 is eliminated, and the motor is driven with the arm 16 within the rotation trajectory of the wheel gear tip 2250. When the switch is operated, the tip 225 and the arm 16 interfere,
It may not operate normally and may damage or damage the respective contact surfaces.

In the embodiment, since the arm 16 is provided with the extension part 229,
Even if an overload is applied, it will not fall within the operating trajectory of the wheel gear, and normal operation can be ensured by operating the switch.

Further, by setting the gap 230, the arm and the convex part do not interfere with each other during normal manual operation, so there is no sound of the resins hitting each other, and a good operation feeling can be obtained.

A switch that detects locking and unlocking by key operation will be described in detail. No. 22゜47.23.
48.49Refer to Figure 48.49. The detection switch 205 includes a main body 207 fixed to the housing 2' by a screw 206 or the like, and is rotatably supported by the main body 207, with one end 2
08 is inserted into the hole 209 of the key operation lever 13, and the movable part 21 operates in conjunction with the rotational operation of the key operation lever 13.
0, and has a contact part and a conductive part similar to those shown in FIG. 21 inside, and detects the locked and unlocked positions.

211 is a wire harness connected to the detection switch 205.

The housing 2' is provided with a cavity 212 for accommodating the main body 207, and a hole 213 into which the screw 5206 is tightened.

A substantially U-shaped groove 214 is formed by walls 215 and 216, serves as a passage for the wire harness 211, and is continuous with a passage 217 provided in the side wall. A clip 218 is latched onto the wall 215 and its upper end piece 219 closes the opening of the groove 214 to prevent the wire harness 211 from jumping out of the groove 214. Note that FIG. 60 is a view seen from arrow N in FIG. 47.

The wire harness 211 is fixed to the housing with a clamp 186 as shown in FIG. 57, similar to the embodiment shown in FIG. 51.

In this way, the wire harness 211 is firmly held on the upper surface of the housing 2' by the clip 218 and the clamp 186, and sufficient space can be given to the glass lifting trajectory 114 in FIG. It is possible to obtain a compact door lock that requires less space and has a high degree of freedom in placement on a vehicle.

If there is sufficient space between the door glass lifting path 114 and the side surface of the housing for the wire harness 211 to pass through, the wire harness 211 can be attached to the hook 231 provided on the housing 2 as shown in FIGS.
By locking the harness, it is possible to prevent the harness from floating freely from the surface of the housing 2', and the number of parts and assembly work are cheaper compared to the one using the clamp 186 shown in Fig. 22.48. .

Please refer to FIGS. 47, 23, and 24. The rotation of the key operation lever 130 is transmitted to the protrusion 15 of the locking arm 9 through the protrusion 14 and step 14', thereby causing the locking arm 9 to rotate.

In order to ensure a sufficient gap with respect to the glass elevation locus 114 in FIG. 24, the switch 205 needs to be placed closer to the door lock.

As shown in FIG. 23, in order to overlap the switch 205 near the rotation center of the key operation lever 13 and the locking arm 9, the protrusion 15 is bent toward the housing 2', and the protrusion a'B15 and the housing 2', a recess 220 is provided between the operating range of the protrusion 15.

By adopting this arrangement, the switch 205 can be moved closer to the door lock side.

In addition, a recess 221 is provided on the bottom surface of the movable part 210 of the switch 205.
By providing this and avoiding interference between the locking arm 9 of the output shaft 10 and the caulking portion 222, the switch 205 can be moved further toward the housing side.

FIG. 50 shows details of the fastening portion between the main body 207 and the housing 2'.

The main body part 207 is provided with a boss part 223 extending toward the mounting surface of the housing 2', and is provided with a hole 224 into which the boss part 223 provided on the housing 2' is inserted to determine the position of the switch 205. ing.

In this manner, the boss portion 223 and the hole 224 allow the switch 205 to be installed in a correct relationship between the one end 208 of the movable portion 210 and the hole 209 of the key operating lever 13, thereby accurately detecting locking and unlocking.

Please refer to FIGS. 29 and 51. 184 is the motor 26
, is a wire harness wired to the conductive part of the board 122, and is fixed to the housing with a clamp 186 that passes through a clamp hole 185 provided in the housing 2.2'. Therefore, when assembling it into a vehicle, you need to pull the connector (not shown) at the end of the wire harness and connect it to the mating connector, or hold the connector.
Even if the door rotor body is hung, this tensile load is borne by the aforementioned clamp 186 and does not extend to the part housed in the housing, so it is not applied to the joint with the motor or the conductive part of the board. By not causing damage, it is possible to prevent immobility due to disconnection.

FIG. 52 shows the 0
a harness holding part 198 showing a ring 119, through which a wire harness disposed at the conductive part of the motor and the board passes;
Grip part 1 that improves workability when inserting into groove 118
99 are available.

FIG. 53 shows details of the grip part 199 with protrusions 20 on the outer periphery.
0, and the diameter 201 is set to be slightly larger than the width of the groove 118 described above. In order to reduce the external shape of the drive unit, the groove 118 has a meandering shape with few straight parts, as shown in Fig. 24, so that when the O-ring 119 is inserted into the groove 118 and the cable is routed, the O-ring itself becomes linear. Due to the restoring force of trying to return, it jumped out of the groove, making it extremely difficult to work with.

In the embodiment, by providing several grips 199 with an outer diameter larger than the groove width, it is possible to prevent the above-mentioned phenomenon of protruding from the groove, and the insertion work is greatly improved, and the housings 2 and 2' It will not get caught outside the designated position, impairing the sealing performance, allowing water, debris, etc. to enter the housing, and reducing the function of the drive unit.

FIG. 54 is the N parent view of FIG. 52, and is provided with a hole 202 through which the wire harness passes.

FIG. 55 is a cross section taken along line PP in FIG. 54, and a convex portion 203 having a diameter smaller than the outer diameter of the harness is provided inside the hole 202.

FIG. 56 shows the harness holding part 19 in the housing 2.2'.
8 is attached, and the housings 2 and 2' are provided with protrusions 204 and 204', which press against the harness holding part 198.

Rainwater and dust cannot enter between the harness and the hole 202.
This is prevented by the protrusion 203 and also by the protrusion 204.204' between the harness holding part 198 and the housing 2.2'.

Further, the convex portion 203 has a function of restricting the movement of the harness, and prevents slippage when a load is applied to the tip of the harness.

(Effect) Even if a load is applied to the tip of the wire harness, the wire harness is fixed to the housing with a clamp, etc., so the load is not transmitted to the wire harness placed inside the acticoator, and the motor or switch inside the acticoator In this application, it is possible to protect the parts connected by, etc.
