It can be actuated to a release position that allows door release operation. On one side surface of the worm wheel 3, an engaging portion 3a protruding toward the operating lever 6 side is formed, and the engaging portion 3a is recessed on one side surface of the operating lever 6 so that the shaft cylindrical portion 6a is formed. A substantially Y-shaped link groove having an arc-shaped idle groove 8a having a length corresponding to the operation stroke of the locking / unlocking lever at the center and an engagement groove 8b extending radially from the center of the idle groove 8a. 8 is movably engaged.

The worm wheel 3 is normally stopped at the neutral position where the engaging portion 3a is engaged in the idle groove portion 8a of the link groove 8, and in this state, the door lock device is manually operated. When the locking / unlocking operation is performed, the engaging portion 3
a only relatively moves within the idle groove portion 8a of the linking groove 8, and the operating lever 6 and the output lever 7 do not interlock with the worm wheel 3 and the motor 1 of the speed reduction mechanism, and perform a light manual operation. be able to.

When a lock operation by a key cylinder or other means is detected by an anti-theft operation switch (not shown), the worm wheel 3 is rotated from the neutral position and the engaging portion 3 is rotated.
a engages with the engaging groove portion 8b of the linking groove 8 and stops at the antitheft position where the actuating lever 6 is prevented from moving in the releasing direction, thereby preventing unlocking of the door lock device by fraudulent activity. Further, when the state where the key is inserted into the ignition key cylinder is detected, the worm wheel 3 is in the unlocking restraining position where the engaging portion 3a is engaged with the engaging groove portion 8b of the linking groove 8 at the unlocking position of the operating lever 6. Then, the operation lever 6 is prevented from moving in the locking direction to prevent the key from being contained in the vehicle.

It is used to swing in the locking / unlocking direction.

Therefore, when the operating stroke of the locking / unlocking lever increases, the swinging stroke of the operating lever 6 also increases, the arc length of the idle groove 8a increases, and the diameter of the worm wheel 3 increases, so that the locking / unlocking operation described above increases. There is a problem that the operating device becomes large. Further, the linking groove 8 recessed in the swingable actuating lever 6 and engaged with the engaging portion 3a projecting from one side surface of the rotatable worm wheel 3 allows smooth movement of the engaging portion 3a. In order to make it possible, the cam shape tends to be complicated, and further, the worm wheel 3 and the operating lever 6 are required to have high assembly precision. Therefore, the conventional locking / unlocking device as described above has a problem that the manufacturing cost is likely to increase.

As shown in FIG. 1, an arcuate groove 43 extending along the outer peripheral edge and a slider fitting groove 44 extending in the radial direction are formed on the upper surface of the lock gear 15. The groove 43 includes a spring accommodating portion 43a for accommodating the coil spring 50 and a pin escape portion 43b communicating with both ends of the spring accommodating portion 43a, and the groove width of the pin escape portion 43b is the spring accommodating portion 43a. Narrower than the groove width of. Therefore, FIG.
As shown in FIG. 6, the coil spring 50 accommodated in the spring accommodating portion 43a has both end portions supported by the stepped portions 65a and 65b, and both end portions thereof project from the inner wall surface of the exterior lid 14. The pair of locking pins 45a and 45b thus brought into contact with each other (see FIG. 1). Therefore, when the lock gear 15 rotates in the forward and reverse rotation directions, the coil spring 50 causes the locking pin 45 to rotate.
a or the locking pin 45b is pressed and compressed. As a result, when the force for rotating the lock gear 15 in the forward and reverse rotation directions is removed, the lock gear 15 returns to the neutral position (the position shown in FIG. 2) by the biasing force of the coil spring 50. That is, the coil spring 50 and the locking pins 45a and 45b
Thus, a biasing means for biasing the lock gear 15 to the neutral position is configured.

The slider fitting groove 44 comprises a slider insertion portion 44a near the center of rotation and a slider support portion 44b near the outside. The slider support portion 44b has an opening width narrower than that of the slider insertion portion 44a. An inwardly-extending space is formed. Therefore, the slider 20 having an inwardly widening cross-sectional shape is slid only in the radial direction by being moved to the slider support portion 44b side after being inserted from the slider insertion portion 44a into the slider fitting groove 44. Freedom.

On the inner wall surface of the outer cover 14 facing the upper surface of the lock gear 15, first and second engagement support portions 23 and 25, with which the engagement portion 21 of the slider 20 can be engaged and disengaged, are formed at both ends. A substantially arc-shaped engaging groove 27 and shaft supporting portions 47 and 46 that pivotally support the ends of shafts 33 and 34 that rotatably support the worm wheel 31 and the position gear 16. ing. Therefore, when the lock gear 15 is rotated from the neutral position in the forward and reverse rotation directions to the locking position or the unlocking position, the engaging portion 21 of the slider 20 also moves along the engaging groove 27, and the neutral position.

(FIG. 7B and FIG. 11B)
reference). Incidentally, these first and second engagement support portions 23, 2
The detailed structure and operation of No. 5 will be described later together with the operation description.

That is, for example, the lock gear 15 is rotated counterclockwise in FIG. 5 by the motor 11, and the engagement portion 21 is engaged with the engagement portion 60 of the first engagement support portion 23. As a result, the lock gear 15 is stopped at the locking position, and the rotation in the unlocking direction is restricted.
Further, the lock gear 15 is rotated in the clockwise direction in FIG. 5, and the engagement portion 21 is engaged with the engagement portion 70 of the second engagement support portion 25, whereby the lock gear 15 is locked. Is stopped at the unlocked position and is restricted from rotating in the locking direction.

Next, the operation of the door lock locking / unlocking operation device of the present invention constructed as described above will be described. In FIG. 5, the lock gear 15 is positioned at the neutral position by the biasing force of the coil spring 50, and the locking projection 42 of the lock gear 15 is engaged with one end (the right end in FIG. 5) of the idle groove 41 of the position gear 16. The door lock is normally unlocked. In this state, when the locking / unlocking lever 17 of the door lock device (not shown) inside the door car is rotated in the direction of arrow X in FIG. 1 to perform the locking operation, the output shaft 36 and the final gear 35 are used to move to the unlocked position. The gear 16 rotates in the counterclockwise direction to move to the lock position, and as shown in FIG. 6, the locking projections 42 move from one end to the other end of the idle groove 41 (in FIG. 6,
It moves relatively to the left end) and becomes a normal locked state.

When the locking / unlocking lever 17 is unlocked from the normal locked state, the position gear 16 rotates clockwise to the unlocked position, and the locking projection 42 causes the other end of the idle groove 41 to move. It moves relatively from one end to the normal unlocked state. Therefore, when the locking / unlocking lever 17 is manually locked / unlocked, the locking projections 42 only move relatively in the idle groove 41, and the lock gear 15
Since and are not engaged, a manual operation can be performed easily.

Next, when the operating switch (not shown) provided in the vehicle compartment is locked from the normally unlocked state shown in FIG. 5, the motor 11 rotates in the normal direction, and the worm 30 rotates the worm wheel 31 in the clockwise direction. Therefore, the lock gear 15 is rotated counterclockwise against the biasing force of the coil spring 50. At this time, the coil spring 50 is compressed and biased between the stepped portion 65a of the groove 43 and the locking pin 45b of the outer cover 14. Then, the position gear 16 is rotated counterclockwise together with the lock gear 15 by the locking projection 42 of the lock gear 15 that engages with one end (the right end in FIG. 5) of the idle groove 41, and Since it is moved to the lock position as shown in (a), the locking / unlocking lever 17 is moved through the final gear 35 and the output shaft 36 to the arrow X in FIG.
The door lock device is locked by being rotated in the direction.

At this time, the engaging portion 21 of the slider 20 is normally in the locked position as shown in FIG.
6 is not locked by the locking portion 60 of the engagement support portion 23, the lock position of the position gear 16 is detected by a position switch (not shown), and when the energization of the motor 11 is stopped, as shown in FIG. Lock gear 1 as shown
5 is returned to the neutral position by the urging force of the coil spring 50. At this time, the locking projection 42 only moves in the empty groove 41 from one end to the other end (the left end in FIG. 6),
Since it is not engaged with the position gear 16, the position gear 16 normally remains in the locked state.

When the operation switch is unlocked from the normally locked state shown in FIG. 6, the motor 11 reversely rotates,
Since the worm 30 rotates the worm wheel 31 in the counterclockwise direction, the lock gear 15 is rotated in the clockwise direction against the biasing force of the coil spring 50. At this time, the coil spring 50 is provided with the step portion 65b of the groove 43 and the outer lid 1.
4 and the locking pin 45a of No. 4 are compressed and biased. And
The position gear 16 is rotated clockwise with the lock gear 15 by the locking projection 42 of the lock gear 15 that engages with the other end of the idle groove 41, as shown in FIG.
Since it is moved to the unlocked position as shown in FIG.
Is rotated and the door lock device is unlocked.

At this time, the engagement portion 21 of the slider 20 is not engaged with the engagement portion 70 of the second engagement support portion 25, as shown in FIG. When the lock position of the position gear 16 is detected by the position switch and the energization of the motor 11 is stopped, the lock gear 15 moves to the coil spring 50 as shown in FIG.
The urging force of returns to the neutral position. At this time, the locking projection 42 extends from the other end to the one end (the right end in FIG. 5) in the empty groove 41.
The position gear 16 normally remains in the unlocked state because it only moves relative to the position gear 16 and is disengaged from the position gear 16.

Next, in the normally locked state shown in FIG. 6, when a lock-off operation switch (not shown) consisting of a keyless entry or a dedicated switch is operated to lock, the motor 11 rotates forward and the lock gear 15 causes the coil spring 50 to urge the coil spring 50. Again, the lock gear 15 is rotated in the counterclockwise direction (locking direction) again, but in this case, the lock gear 15 is rotated by an angle α more than the normal locking angle shown in FIG. 7A. (See FIG. 8). Therefore, the engaging portion 21 of the slider 20 is moved inward in the radial direction by the first-step cam surface 61 of the first engaging support portion 23, and as shown in FIG. Reach the center of 61.

When the motor 11 is de-energized, the biasing force of the coil spring 50 causes the lock gear 15 to rotate clockwise in an attempt to return to the neutral position. However, when the lock gear 15 returns to the normal locking angle, the engaging portion 21 is engaged with the engaging portion 60 of the first engaging support portion 23 as shown in FIG. Since the rotation of the lock gear 15 is restricted, the lock gear 15 is stopped at the locking position shown in FIG. At this time, as shown in FIG. 9B, the engaging portion 21 of the slider 20 has the engaging portion 6
It is moved inward in the radial direction by the zero cam surface 60a, reaches the center portion of the cam surface 60a, and is positioned at the anti-theft locking position.

In this anti-theft lock state, the slider 2
The engaging portion 21 of 0 is locked to the locking portion 60, the movement of the lock gear 15 in the unlocking direction (clockwise direction) is blocked, and the locking projection 42 has one end of the idle groove 41 ( It is located on the right end side in FIG. Therefore, even if the operation switch is unlocked and the motor 11 is rotated in the reverse direction, the lock gear 15 cannot rotate in the unlocking direction. or,
The position gear 16 cannot rotate in the clockwise direction relative to the lock gear 15, and is restricted from rotating in the unlocking direction. That is, the locking / unlocking lever 17 that rotates together with the position gear 16 is also restricted from rotating in the unlocking direction. Therefore, the position gear 16 can reliably prevent the locking / unlocking device of the door lock from being released by an illegal act.

When the anti-theft operation switch (not shown) is unlocked in the anti-theft lock state shown in FIG.
Is rotated in the normal direction, and the lock gear 15 is again rotated counterclockwise by the angle α from the normal locking angle against the biasing force of the coil spring 50 (see FIG. 10). Therefore, the slider 2
The engaging portion 21 of 0 is moved inward in the radial direction by the cam surface 62 of the second stage of the first engaging support portion 23, and as shown in FIG. Reach the center.

Then, the power supply to the motor 11 is stopped,
When the lock gear 15 is rotated in the clockwise direction by the urging force of the coil spring 50, the engaging portion 21 is locked by the engaging portion 60.
Since the engagement with the first engagement support portion 23 is released without being locked by the lock gear 15, the lock gear 15 returns to the neutral position shown in FIG. 6 and is normally locked. Therefore, the position gear 15 can be rotated in the unlocking direction by the locking / unlocking lever 17 and the operation switch as described above.

Next, when the detection means (not shown) detects the key insertion of the ignition key cylinder and the open state of the door, the motor 11 rotates in the reverse direction and the lock gear 15 rotates clockwise against the biasing force of the coil spring 50. The lock gear 15 is rotated in the direction (unlocking direction) in this case.
It is rotated by an angle β more than the normal unlocking angle shown in (a) (see FIG. 12). Therefore, the engagement portion 21 of the slider 20 is moved inward in the radial direction by the first-step cam surface 71 of the second engagement support portion 25, as shown in FIG.
As shown in (b), the cam surface 71 reaches the center portion.

When the motor 11 is de-energized, the biasing force of the coil spring 50 causes the lock gear 15 to rotate counterclockwise in an attempt to return to the neutral position.
However, when the lock gear 15 normally returns to the unlocking angle,
As shown in FIG. 13B, the engagement portion 21 is engaged with the engagement portion 70 of the second engagement support portion 25, and rotation in the counterclockwise direction is restricted. Is stopped at the unlocked position shown in FIG. At this time, the engaging portion 21 of the slider 20 is moved inward in the radial direction by the cam surface 70a of the engaging portion 70 to move toward the center of the cam surface 70a, as shown in FIG. 13 (b). Reached and is placed in the unlocked restraint position.

In this unlocked state, the slider 2
The engaging portion 21 of No. 0 is locked to the locking portion 70, the movement of the lock gear 15 in the counterclockwise direction (locking direction) is blocked, and the locking protrusion 42 is the other end of the idle groove 41. It is located on the (left end in FIG. 13) side. Therefore, even if the operation switch is locked and the motor 11 is rotated in the forward direction, the lock gear 15 cannot be rotated in the locking direction. Further, the position gear 16 cannot rotate in the counterclockwise direction relative to the lock gear 15, and is restricted from rotating in the locking direction. That is, the locking / unlocking lever 17 which rotates together with the position gear 16 is also restricted from rotating in the locking direction. Therefore, it is possible to prevent the door lock device from being inadvertently locked while the key is still inserted in the ignition key cylinder to keep the key in the vehicle.

In the unlocked state shown in FIG. 13, when the detection means (not shown) detects the key removal of the ignition key cylinder or the closed state of the door, the motor 11
Reversely rotates, and the lock gear 15 is again rotated clockwise by an angle β from the normal unlocking angle against the biasing force of the coil spring 50 (see FIG. 14). Therefore, the slider 20
Of the second engaging support portion 25 is moved inward in the radial direction by the second cam surface 72 of the second engaging support portion 25.
As shown in FIG. 14B, the cam surface 72 reaches the center portion.

Then, the power supply to the motor 11 is stopped,
When the lock gear 15 is rotated in the counterclockwise direction by the biasing force of the coil spring 50, the engaging portion 21 causes the engaging portion 21 to move.
Since the engagement with the second engagement support portion 25 is released without being locked at 0, the lock gear 15 returns to the neutral position shown in FIG. 5 and is normally in the released state. Therefore, the position gear 15 can be rotated in the locking direction by the locking / unlocking lever 17 and the operation switch as described above.

The door lock locking / unlocking operation device according to the present invention is not limited to the above embodiment, and it goes without saying that various forms can be adopted based on the gist of the present invention. For example, in the above-described embodiment, the rotation of the motor 11 is transmitted to the lock gear 15 via the reduction mechanism including the worm 30 and the worm wheel 31,
The lock gear 15 may be directly driven by using a motor capable of generating high torque at low rotation.
Further, the door lock locking / unlocking operation device of the present invention can be interlocked with a switch that operates when the speed of the vehicle exceeds a predetermined speed, a switch that operates when the vehicle collides, and the like.

[0037]

As described above in detail, according to the locking / unlocking operation device for the door lock according to the present invention, the rotation for locking can be rotated from the neutral position to the locking position or the unlocking position by one motor. The body and a transmission rotary member that engages with the locking / unlocking lever of the door lock device via the transmission means are coaxially arranged. Therefore, the device can be downsized as compared with the conventional locking / unlocking operation device including the actuating lever that swings integrally with the locking / unlocking lever. That is, even if the operating stroke of the locking / unlocking lever is increased, the rotation angle of the transmission rotary member in the present invention may be increased, and it is not necessary to increase the diameters of the locking rotary member and the transmission rotary member. Further, an engaging portion that engages with an engaging groove formed in the outer cover is provided on one side surface of the lock rotating body and is provided on a slider that is movable in the radial direction. Therefore, without increasing the accuracy of assembling the outer cover and the lock rotor, and without complicating the cam shape of the engaging groove, the engaging portion can be smoothly moved along with the rotation of the lock rotor. It is possible to suppress an increase in manufacturing cost. Therefore, with a simple structure, an inexpensive locking / unlocking operation device for an automobile door lock can be performed, which enables locking / unlocking operation of the door lock device by a motor and a manual operation, and also prevents unlocking operation by fraudulent activity and lock of the key in the vehicle. Can be provided.
