Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field of the Invention] The present invention relates to a door lock device that requires a turning output such as an actuator for locking an automobile or an indoor door. This invention relates to a door lock device that produces extremely low operating noise and can provide high-speed and clear rotational output.

[Problems with the Prior Art] Various electric actuators have conventionally been employed in door lock devices used in door lock mechanisms for automobiles, interior rooms, and the like. However, in the case of conventional door lock devices using electric actuators, most of them use electromagnets, and they have the disadvantage of generating harsh and loud impact noises when activated. In some cases, such harsh and loud impact noise is extremely undesirable, and recently attempts have been made to reduce the noise by using a DC motor with a core structure.

However, door lock devices using DC motors simply use the DC motor as is, and the DC motor does not have an optimal design structure that matches the mechanical mechanism of the door lock device. Because the DC motor does not take into account the performance of the device itself, such as a door lock mechanism, the door lock device has a complicated configuration using multiple gear stages consisting of a large number of gears, resulting in a large and expensive door lock device. It was equipped with

Moreover, the structure of the DC motor is inefficient and has a radial gap type iron core structure, which causes large cogging and impedes clean operation, resulting in poor response. In addition, since multiple gear stages are used, responsiveness is also poor in this respect.Also, it is necessary to manually lock the door, for example, in the door lock mechanism, but since multiple gear stages are used, However, the disadvantage is that it requires a large amount of force, and it also has the disadvantage of causing a large amount of release.

Yet again. As a car door lock device.

In recent years, the thickness of car doors has become thinner.
Due to limited storage space for the door lock device,
Conventional door lock devices using a DC motor with a core structure using multiple gear stages have the disadvantage that it is difficult to rationally incorporate them into the thin door.

[Problem of the Invention] An object of the present invention is to provide a door lock device for an automobile, etc., which can be stored extremely easily and rationally even when built into a device with limited space, such as a thin automobile door. The object of the present invention is to provide a door lock device in which the actuator used therein can be made small and flat and mass-produced at low cost.

In achieving this goal, by using a small number of gears instead of multiple gear stages at the same time, the configuration can be simplified, one assembly can be easily performed, and mass production can be performed at low cost.
In addition, it enables smooth operation and high-speed response without using a DC motor with a core structure.
The object of the present invention is to provide a door locking device that can be easily locked with a small force when locking the door in a door locking mechanism, and that generates only an extremely small operating noise and a small impact force. It is.

Another issue is to enable the axial gap type coreless commutator rotating actuator mechanism of a suitable structure to be easily and rationally incorporated into the door lock device, which serves as the power unit used in the door lock device. In addition, a commutator is manufactured by forming a printed circuit board on a coreless rotating armature with a conductive pattern for electrical connection for electrically connecting the commutator, armature coil, and commutator pieces to each other. The commutator, the brushes, and the conductive wire for electrical connection are made by placing and fixing this as a dual-purpose electrical connection board on the surface of the coreless rotating armature, and slidingly contacting the brush from the axial direction with the commutator of the commutator-cum-electrical connection board. Even if a patterned printed circuit board is used, the size of the axial gap type coreless commutator rotation actuator mechanism, which is the power section, will not be increased.

In particular, the rotary actuator mechanism has a very thin thickness in the axial direction, and the number of parts is reduced to facilitate assembly. By making the electrical connection with the armature coil extremely easy and making it possible to easily and inexpensively mass-produce an axial gap type coreless commutator rotation actuator mechanism.

The object of the present invention is to provide a door lock device that meets the above-mentioned problems.

Another objective was to simplify the structure of the axial gap type coreless commutator rotary actuator mechanism, which has smooth torque ripple and good performance, and to extend the life of the door lock device.

Other issues will become clear in the discussion below.

[Means for Achieving the Object of the Invention] The object of the invention is to provide a field magnet as a stator, which is formed by alternately 2P N poles and SI magnetic poles (P is an integer greater than or equal to 1) on the stationary side. A coreless rotary armature of m (m is the number of phases and an integer of 2 or more) consisting of k (k is an integer of 2 or more) armature coils can be freely rotated through a magnetic magnet and an axial air gap. a commutator is provided on the coreless rotating armature so that the armature rotates integrally with the coreless rotating armature; a brush that makes sliding contact with the commutator is provided on the fixed side; A driven gear, which is fixed to an output gear shaft in which gears are arranged concentrically and supported so as to be rotatable once, and which is rotatable at a predetermined angle, is meshed with the main drive gear so as to interlock with the main gear directly or through an appropriate means. and an output lever that provides a mechanical output to the locking/unlocking side of the door is attached to the output gear shaft to which the driven gear is attached substantially orthogonally to the output shaft, and the output lever is configured to be freely pivotable. This can be achieved by

Another problem is that the above coreless rotating armature surface has a 2mm diameter.
A commutator consisting of commutator pieces (n is an integer greater than or equal to 1) and a conductive pattern for electrical connection in which commutator pieces that are at equal positions in correspondence with the magnetic poles of a field magnet are electrically connected to each other. In order to fix the commutator/electrical connection board formed by forming the commutator/electrical connection board, and to make sliding contact with the commutator of the commutator/electrical connection board to effect rectification, they are arranged at an interval of 90 degrees from each other, and are connected to a positive side power source and a negative side power source, respectively. Two brushes connected to the side power source are provided on the fixed side, and the commutator/electrical connection board is installed on the coreless rotating armature so that the commutator surface faces the opposite side to the field magnet side. The above coreless rotating armature may be placed on the opposite side of the field magnet.
A group of air-core armature coils each having a conductor portion whose opening angle contributes to at least the generated torque is formed with an opening angle width within 160 degrees to 220 degrees in electrical angle are arranged so as not to overlap each other. The field magnet may be formed with four poles, and the armature coil may include three armature coils arranged at equal intervals so as not to overlap each other, or the commutator/electrical connection board may be formed of copper. This can be achieved by forming a tensile laminated magnetic substrate.

Since the door lock device 1 is arranged and fixed on the inner surface of a door (not shown) parallel to the door wall and stored inside the door, the door lock device main body 2 can be formed into a thin rectangular cube. A rectangular shape with a hollow interior and an open bottom end (the side surface in Figure 1) made of an appropriate material such as a magnetic material such as a mild steel plate, die-cast aluminum, or resin. It is formed by closing the open end of the cubic case 3 with the cover 4 using screws 25. For this reason, a screw hole 26 for inserting the screw 25 is provided at the open end of the case 2, and a through hole 27 for inserting the screw 25 is formed in the cover 4.

The coreless rotating armature 1° consisting of 9-3 is made by fixing the three air-core armature coils 9-1°..., 9-3 to the commutator/electrical connection board 12 using adhesive or the like. However, in this embodiment, in order to make the coreless rotating armature 10 solid, three air-core armature coils 9-1, 9-2 are used as shown in FIG. .9-3 are arranged at equal intervals at a pitch of 120 degrees so as not to overlap each other, and molded and solidified with resin 43 to form a disk shape. In order to clarify the shape of the armature coils 9-1, 9-2, 9-3, they are shown without being molded with resin 43. ].

．． 15-3, these electrical connection conductive patterns 15-1, 15-2, and 15-3 are used to electrically connect commutator pieces that are in equal conditions in relation to the field magnet 11. (See FIG. 5).Since the 3-phase axial gap type coreless commutating 1,000-turn actuator mechanism 8 of this embodiment employs the Δ connection, one side of the copper-clad laminated magnetic substrate 13 Only when trying to form all three conductive patterns 15-1, 15-2, and 15-3 for electrical connection.

Since any of these conductive patterns for electrical connection will cross each other, in order to solve this problem, in this embodiment, the conductive patterns for electrical connection 15-1 and 15-

Further, the brush holder 24 is mounted and fixed to the case 3 so as to be disposed at the above position via a brush mounting through hole 17 formed in the case 3.

Further, the lead wires 19-1 and 19-2 are led out of the door lock device main body 2 through a through hole 29 formed in the case 3.

On the upper surface of the cover 4, which faces the lower surface of the coreless rotary armature 10 through an axial gap, N-pole and S-pole magnetic poles are connected via a circular stator yoke 18 with a magnetization width of 90 degrees. An annular field magnet 11 having four poles alternately is fixed.

With the above configuration, three highly efficient
A phase axial gap type commutator rotation actuator mechanism 8 is configured.

In addition, in the above embodiment, the Δ connection was shown.

The present invention is not limited to this, and a Y-type connection may also be used.

Although the field magnet 11 is an annular one with four integrated poles, the present invention is not limited to this. Each magnetic pole can be formed using a segment magnet, and a brush holder can be used in the empty space between the segment magnets to attach the brush 23. -1.23-2 may be installed.

Furthermore, although the axial gap type coreless commutator rotating actuator mechanism 8 has been shown as an example of a three-phase motor arrangement in which the armature coils do not overlap each other, the armature coils may overlap each other, and other numbers of phases, That is, the structure of an m (m is the so-called number of motor phases, an integer of 2 or more) phase axial air gap type coreless commutator rotating actuator mechanism consisting of k (k is an integer of 2 or more) armature coil groups. You can also do it.

Yet again. The armature coil used was an air-core type made by winding many turns of conductive wire, but coreless armature coils formed using other methods such as sheet coils formed using etching means or pressing means, and printed coils, etc. It may be formed by using

Furthermore, although the commutator 14 is shown as being formed of six commutator pieces, it may also be formed using 2 mn (n is an integer of 1 or more). For example, in the axial direction of the three phases shown above, In the air gap type coreless commutator rotating actuator machine 18, in the above 2rnn.

Since it is a 3-phase motor arrangement, 2m = 3 and n = 1,
That is, 2X3X1=6, and the commutator 14 is made up of 6 commutator pieces.
was configured, but if n=2 is selected, 2x3X2=12
Since the commutator 21 is formed of commutator pieces, the number of torque ripples is doubled compared to that of the above embodiment, that is, the size of the torque ripples can be reduced to about half. Therefore, it is possible to form a three-phase axial gap type coreless commutator rotation actuator mechanism 8 that rotates more smoothly.

Further, in the above embodiment, the copper-clad laminated magnetic substrate 13
The commutator-cum-electrical connection board 12 is used, but the reason for doing so is to take into consideration the case where the axial gap type coreless commutator rotating actuator mechanism 8 is arranged vertically.

In other words, if the coreless rotating armature 10 is not equipped with a magnetic material, it will vibrate in the axial direction when it rotates.
In order to prevent this, the coreless rotating armature 10 is magnetically attracted to the field magnet 11 side using the commutator/electrical connection board 12 made of the copper-clad laminated magnetic substrate 13, and the coreless rotating armature 10 is magnetically attracted to the field magnet 11 side. This is because axial vibration of the armature 10 is prevented. Of course, since the copper-clad laminated magnetic substrate 13 closes the magnetic path of the field magnet 11, it also serves the purpose of increasing efficiency. However, by forming the case 2 from a magnetic material, or by separately attaching a small magnetic material to the coreless rotating armature 10.

If the above measures are unnecessary, a printed circuit board made of a non-magnetic substrate may be used.

Although the stator yoke 18 is used, it can be omitted if the cover 4 is made of a magnetic material. This is because consideration has been given to the case where it is formed of a magnetic material.

That is, the @ tension laminated magnetic substrate 13 is the field magnet 1
This is used for the purpose of omitting the spring mechanism and closing the magnetic path of the field magnet 11 by magnetically attracting the case 3 to the case 3. In this case, an insulating substrate such as a printed circuit board made of a non-magnetic material may be used instead of the copper-clad laminated magnetic substrate 13 constituting the commutator/electrical connection board 1.

It is desirable to add an appropriate magnetic material to an appropriate position of the coreless rotating armature 10 to prevent vibration of the coreless rotating armature 10 in the axial direction.

On the upper surface of the coreless rotary armature 10, a main drive gear 28 with a small diameter and concentrically arranged with the shaft 5 through which the shaft 5 is passed is fixedly installed.

A through hole 31 having a two-step portion 31a is formed in the case 3,
A metal 30 such as Orres metal having a stepped portion 30a having a bearing function is attached to the through hole 31 by engaging the stepped portions 31a and 30a, and the swing driven gear 32 is attached by the metal 30. The upper end portion of the output gear shaft 33 is rotatably supported. In addition, a through hole 34 is formed in the cover 4, and a metal 35 such as Orres Metal having a stepped portion 35a having a bearing function is attached to the through hole 34, and a swing driven gear 32 is attached by the metal 35. The lower end portion of the output gear shaft 33 is rotatably supported. As a result, the output gear shaft 33 and the swing driven gear 32 are supported so as to be able to rotate once.

The swing driven gear 32 has a long hole 32a formed in an end portion 32c.
Pass the output gear shaft 33 through the output gear shaft 3.
3 is engaged with a stepped portion 33a formed at the upper end portion of No. 3. The rotating driven gear 32 is formed into a fan-like shape, and has a toothed portion 32b formed on its outer periphery, and the toothed portion 32b meshes with the toothed portion of the main drive gear 28.

In this embodiment, the gear ratio between the main drive gear 28 and the swing driven gear 32 is set to 1:5, so that when the main drive gear 28 rotates once, the swing driven gear 32 turns 72 degrees. It has become.

As described above, in this embodiment, in order to regulate the turning angle of the turning driven gear 32, the turning angle regulating protrusions 36-1 and 36-2 of the turning driven gear 32 are formed at two locations on the case 3,
Turning driven gear 3 of the turning angle regulating protrusion 36-1.36-2
A stopper rubber 37 for absorbing impact force is attached to a portion that comes into contact with the radially extending side surface 32d of 2. In addition, in order to prevent the swing driven gear 32 from rotating by one repulsion due to the impact force when the swing driven gear 32 rotates at a full stroke and comes into contact with the stopper rubber 37, the swing driven gear 32 is rotated by a click mechanism formed as follows. It is maintained at the rotational position.

The click mechanism has studs 38-1 and 38-2 planted near the turning angle regulating protrusions 36-1 and 36-2, and is made of beryllium steel or the like on the surface that slides into contact with the end 32c of the turning driven gear 32. A corrugated leaf spring 39 with four recesses formed in three places is bent into the screw hole of the stud 38-1. It is formed by screwing in and fixing the leaf spring 39.

Therefore, as shown in FIG. 7, when the swing driven gear 32 is in the state shown by the solid line in the same figure [this state is assumed to be the state when the lock of the door lock mechanism is released], the swing driven gear 32 is engaged with the convex portion 39b of the leaf spring 39 and held in that position, and the swing driven gear 32 is
When the plate spring 39 is reversed to the state shown by the dashed line in the figure against the elasticity of the protrusions 39b and 39c, the end 32c of the swing driven gear 32 is engaged with the protrusion 39b of the plate spring 39, and the position is [This state is assumed to be the state when the door lock mechanism is locked].

The output gear shaft 33 rotatably supported by the metal 35 has an upper end protruding through the cover 4, and an output lever 41 having a hole orthogonal to the lower end of the output gear shaft 33 is attached. The through hole 41a formed on the side surface of the output lever 41 and the through hole 33b formed perpendicularly to the lower end of the output gear shaft 33 are aligned, and the stopper 42 is attached to these through holes 41a and 33b, so that the output gear shaft 33 An output lever 41 that is perpendicular to the axial direction of the output gear shaft 33 is fixed to the lower end of the output gear shaft 33 . As a result, an output lever 41 that provides a mechanical output to the locking/unlocking side of the door (not shown) is attached perpendicularly to the output gear shaft 33 to which the swing driven gear 32 is attached. The output lever 41 is rotatable.

Note that the output lever 41 is connected to a door lock button via a door lock mechanism having a door locking/unlocking mechanism such as a connecting link mechanism (not shown).
A door (not shown) can be automatically locked and unlocked by the turning movement of the door.

In addition, when manually locking the door, the door lock button (not shown) can be locked by rotating the output lever 41 via a door lock mechanism (not shown) having a door locking/unlocking mechanism such as a door lock button (not shown) or a connecting link mechanism. The mechanism is locked.

[Second Embodiment of the Invention] FIG. 8 shows a bottom view of a coreless rotating armature 10° used in a second embodiment of the invention.

Coreless rotating armature 10 shown in the first embodiment [Fig. 4]
In the case of Yoshiko coil 9-1. ...The 9-3 group was formed into a disk shape by molding the entire outer periphery with resin 43 and solidifying it, but when locking the door lock mechanism with active movement,
By rotating the output lever 41 via the door lock itR, which has a door locking/unlocking mechanism such as a door lock button (not shown) or a connecting link mechanism, the weight burden on the coreless rotating armature 10 that rotates once is reduced. In order to make it easier to lock the door manually even with a small force, the coreless rotating armature 10' of this embodiment has air-core armature coils 9-1 and 92 of the coreless rotating armature 10. Q: A part of the resin 43 between the armature coils 2-1 and 9-3 and between the side surfaces of the armature coils 9-3 and 9-1 is omitted to form a resin removed portion 43a. There is. Note that, when the coreless rotating armature 10' is molded with resin 43 in advance, the resin removed portion 43a is
It can be easily molded using a metal mold so that a can be formed.

[Third Embodiment of the Invention] The third embodiment of the present invention will be described with reference to FIG.
This door lock device 1' is almost the same as the door lock device 1 of the first embodiment, except that the door lock device 1' includes a switch base 45 and a switch brush 46 in sliding contact with the switch base 45. The point is that a mechanism 44 is built-in.

In order to incorporate this switch mechanism 44, the shape of the door lock device main body 2' consisting of the case 3' and cover 4' and the shape of the output lever 32' are slightly changed. That is, in order to interpose the switch brush 46 that makes sliding contact with the switch base 45 between the stepped portion 33a at the upper end of the output gear shaft 33 and the bearing portion 30° formed protrudingly on the lower surface of the case 3', the output lever 32' is The inner peripheral portion is bent upward to form a bent portion 32'd, and the bent portion 32'
It is fixed to the output gear shaft 33 at the d position, and is formed so that the switch brush 46 rotates together with the rotation of the output gear shaft 33. A brush contact portion at a bent end portion of the switch brush 46 is brought into sliding contact with a switch base 45 disposed on the inner surface of the case 3'. The output lever 41 is attached to the lower end of the output gear shaft 33 in the same manner as described above, but in order to prevent the protruding lower end of the output gear shaft 33 and the output lever 41 from protruding from the bottom surface of the cover 4', the case 4 is Concave step 4'
a, and the output gear shaft 3 is disposed within the concave stepped portion 4'a.
3 and the output lever 41 are accommodated therein.

Further, in this embodiment, a cylindrical commutator 14' consisting of a plurality of commutator pieces is attached to the coreless rotating armature 10, and the commutator 14'' has a cylindrical shape as shown in the above embodiment. Two brushes 23"-1 and 23"-2 disposed on the cover 4" are in sliding contact with each other at an opening angle of 23.degree.

[Operation of the Invention] Since the door lock device 1.1' of the present invention has the above-mentioned configuration based on signals from two controllers (not shown), the positive side power terminals 22-1. Negative power supply terminal 22-2. Lead wire 19-1.192, brush 23-1.23-2
[23°-1°23”-2] and commutator 14 [14']
, conductive pattern for electrical connection 15-1. ..., 15
-3 via the appropriate armature coil 9-1. ..., 9-
When the third group is energized in an appropriate direction, torque is generated in a predetermined direction according to Fleming's left-hand rule, so that the rotor having the coreless rotating armature 10, 10' rotates in a predetermined direction. Also, due to the rotation of this coreless rotating armature 10.10', the brush 23-1.23-2 [23''-1
, 23' -2] and the commutator 14 [14'] rotate relative to each other, commutation is performed, current is passed in an appropriate direction to the armature coil 9 groups, and the coreless rotating armature 10.10
' rotates in the specified direction. The coreless rotating armature 10.
When the coreless rotary armature 10' rotates in a predetermined direction, the main drive gear 28, which is provided concentrically with the shaft 5 of 10 degrees, also rotates in that direction.

As a result, the rotating driven gear 3 meshing with the main driving gear 28
2 [32'] rotates in a predetermined direction.

When the swing driven gear 32 [32'] rotates in a predetermined direction,
Since the output gear shaft 33 rotatably supports and fixes the swing driven gear 32 [32'], it rotates in the same direction, so when the output gear shaft 33 rotates, it is fixed perpendicular to the output gear shaft 33. The output lever 41 rotates in a predetermined direction. Depending on the direction of the rotational movement of the output lever 41, a door locking mechanism having a door locking/unlocking mechanism such as a linkage mechanism (not shown) that is interlocked with the output lever 41 can be activated to automatically lock/unlock the door. can.

In addition, when manually locking the door, the output lever 41 is rotated via a door lock mechanism (not shown) having a door locking/unlocking mechanism such as a door lock button (not shown) or a connecting link mechanism (9) to lock the door (not shown). The mechanism is locked. By turning the output lever 41, the output gear shaft 3
Since the rotating driven gear 32 fixed to the rotation driven gear 32 rotates, the main driving gear 28 that meshes with the rotating driven gear 32 rotates, so that the coreless rotating armature 10.10 degrees rotates in a predetermined direction.

In the case of FIG. 9, the switch brush 45 also rotates due to the rotation of the output gear shaft 33, so the output lever 41 is rotated from the switch base 46 in sliding contact with the switch brush 45 via a reed (not shown). It is now possible to know the direction and position of the movement.

[Effects of the Invention] As is clear from the above, the present invention uses an axial gap type commutator actuator mechanism with a coreless structure.
Since the door lock device can be formed with an extremely thin thickness, it can be stored extremely easily and rationally even when it is built into a device having a limited thickness, such as a thin automobile door.

At the same time, since only a small number of gears are used instead of multiple gear stages, the configuration is simple and two-piece assembly is easy, allowing mass production at low cost.Moreover, it uses an axial gap type commutator actuator mechanism with a coreless structure. Therefore, the torque ripple is small, and smooth operation and high-speed response are possible.For example, when manually locking a door lock in a door lock mechanism, it can be easily done with a small force, and the operation noise is extremely low. It is possible to form a long-life product that generates only a small impact force.

In addition, an axial gap type coreless commutating 1,000-turn actuator mechanism with a suitable structure that serves as the power unit used in the door lock device can be easily and rationally incorporated into the door lock device, and the commutator and electric A printed circuit board with a conductive pattern for electrical connection for electrically connecting the child coils and commutator pieces is formed into one board to serve as a commutator and electrical connection board, and this is placed on the surface of the coreless rotating armature. Since the brushes are in sliding contact with the commutator of the commutator/electrical connection board from the axial direction, even if a commutator, brushes, and a printed circuit board on which conductive patterns for electrical connection are formed are used, the commutator and electrical connection board will be fixed. The axial gap type coreless rectified 1,000-turn actuator mechanism serving as the power part does not become large, and the rotary actuator mechanism can be made extremely thin in the axial direction, and the number of parts can be reduced to facilitate one assembly. Furthermore, the commutator pieces that make up the commutator,
Furthermore, the electrical connection between the commutator pieces and the armature coil is made extremely easy, and the axial gap type coreless commutator rotation actuator mechanism can be easily and inexpensively mass-produced.
