As shown in FIG. 7, the spring 53 urges the slider 34 toward the first rotation position, and the spring 5 projects from the winding portion 53a in the same direction.
It has a substantially U-shape including 3b and 53c. The spring 53 is provided such that the winding portion 53 a is rotatable on the mounting portion 32 of the knob shaft 26. The pieces 53b and 53c are disposed between the protrusion 11 of the upper case 7 and the connecting pin 37 of the slider 34, respectively, and when the knob shaft 26 is rotated to the unlock position, the slider 34 Is biased toward the first rotation position.

Next, the operation of the vehicle door lock actuator will be described. First, in the unlocked state of the vehicle door lock actuator, as shown in FIG. 8, the rotor 18 is rotated so that its engagement convex portion 22 is located on the outer peripheral portion side of the cam portion 43 of the worm wheel 39. Make a state.

In this state, in the knob shaft 26, the connecting groove portion 30 constituting the engaging groove 29 and the long groove 24 of the rotor 18 coincide with each other, and the end edge of the slider in the first rotational position is in the slider position. 34 connecting pins 37 are located. Thus, the rotor 18 and the knob shaft 26 are integrally and rotatably connected by the slider 34. The connected state is determined by the elastic pieces 25 of the rotor 18.
And is held by the bias of the spring 53.

Further, the lock shaft 13 connected to the door lock device is rotated to the unlock position. Therefore, the user can rotate the latch of the door lock device and open the door by operating the inner handle or the outer handle of the vehicle door.

Next, the operation of changing from the unlocked state to the locked state will be described. When the user operates the inner lock knob in the locking direction, the knob shaft 26 first rotates counterclockwise (1) as shown in FIG. Thereby, the rotors 18 integrally connected via the slider 34 rotate together.

Then, the lock shaft 13 engaged with the rotor 18 rotates clockwise (2) in conjunction therewith,
Reach the lock position. As a result, even if the user operates the inner handle or the outer handle of the vehicle door,
The door cannot be opened by rotating the latch of the door lock device.

When the user inserts the key into the cylinder lock and operates in the locking direction, first, the lock shaft 13 connected to the key shaft 12 rotates clockwise (1 ').
To reach the locked position. In accordance with the rotation of the lock shaft 13, the rotor 18 and the knob shaft 26 rotate counterclockwise (2 '). As a result, as described above, even if the user operates the inner handle or the outer handle, the user cannot open the door. Further, in conjunction with the rotation of the lock shaft 13, the rotor 18 and the knob shaft 26 integrally connected via the slider 34 rotate clockwise.

When the user performs an operation of locking the door lock actuator by operating the remote controller, FIG.
As shown at 0, first, the motor 2 is driven to rotate the worm wheel 39 approximately 90 degrees clockwise (1) via the worm gear 3.

Then, in the cam portion 43 of the worm wheel 39, the rotor 18 located on the outer peripheral portion side
Is pressed inward by the first cam wall surface 44 constituting the cam portion 43. As a result, the connected rotor 18 and the knob shaft 26 integrally rotate counterclockwise (2).

Thus, similarly to the above, the lock shaft 13 engaged with the rotor 18 rotates clockwise (3), and the door cannot be opened even if the user operates the inner handle or the outer handle. It is locked.

After the worm wheel 39 is rotated by approximately 90 degrees by the motor 2, it is rotated counterclockwise by the bias of the spring, and returns to the neutral position shown in FIG.

Next, the operation of changing from the unlocked state or the locked state to the super locked state will be described. When the user performs an operation of super-locking the door lock actuator by remote control operation, first, the worm wheel 39 is rotated clockwise (1) by approximately 180 degrees by the motor 2 as shown in FIG. In addition,
When the worm wheel 39 is rotated by 180 degrees from the unlock state to the super lock state, the lock operation is performed at the first 90 degrees, and the super lock operation is performed at the subsequent 90 degrees. Also, when changing from the locked state to the super locked state, the only difference is that no operation is performed in the first 90 degrees, and the super locked operation is performed in the subsequent 90 degrees.

After the worm wheel 39 is rotated, 90
In the cam portion 43, the engagement convex portion 22 of the rotor 18 is brought into a non-interference state by the first circular wall surface 46 in the cam portion 43, and does not act on the rotor 18.

When the rotation of the worm wheel 39 continues, the super lock operation part 48
The slider 34 is rotated clockwise (2) by the rotation of the worm wheel 39. As a result, the connecting pin 37 of the slider 34 slides in the connecting groove 30 in the long groove 24 of the rotor 18 and the engaging groove 29 of the knob shaft 26, and the non-connecting groove 3
1 is located at a second rotation position.

The worm wheel 39 is rotated approximately 180 degrees by the motor 2 and then rotated counterclockwise by the bias of the spring 51 to return to the neutral position shown in FIG. .

In the super lock state, when the user unlocks the inner lock knob, as shown in FIG. 13, the rotor 18 does not interlock and the knob shaft 26 rotates clockwise. Further, the slider 34 is biased by a spring 53 disposed on the knob shaft 26,
It turns to the side of the first turning position.

As described above, even if the inner lock knob is unlocked, the lock cannot be released because the rotor 18 for linking the lock shaft 13 does not rotate. When the user releases the operation of the inner lock knob, the knob shaft 26 is held at that position.
When the inner lock knob is locked, the knob shaft 26 rotates counterclockwise. The slider 34 urged toward the first rotation position by the rotation of the knob shaft 26 causes the connection pin 37 to move to the non-connection groove 31.
The guide surface 31a is pressed again to rotate to the second rotation position, and returns to the state of FIG. The operation of unlocking the door lock actuator with the inner lock knob unlocked will be described later in detail.

Next, the operation for changing from the super lock state to the unlock state will be described. When the user performs an operation of unlocking the door lock actuator by operating the remote controller, first, as shown in FIGS.
It rotates counterclockwise (1).

Specifically, first, the worm wheel 39
Starts rotating from the neutral position, the unlocking operation portion 49 contacts the contact piece 38 of the slider 34 as shown in FIG. Then, the slider 34 is rotated counterclockwise (2) by the rotation of the worm wheel 39 to be in the first rotation position. As a result, the rotor 18 and the knob shaft 26 are again integrally connected, and are brought into a state of rotating coaxially with each other.

Subsequently, when the worm wheel 39 rotates, the unlocking operation part 49 goes over the protruding end of the contact part of the slider 34, and as shown in FIG. 45 is the engaging projection 22 of the rotor 18
Abut. The rotor 18 has an engagement portion of the second
It is pressed outward by the cam wall surface 45. as a result,
The connected rotor 18 and knob shaft 26 rotate clockwise (3) integrally, and the lock shaft 13 rotates counterclockwise (4) in conjunction with this rotation.

Then, the worm wheel 39 is substantially 180
When the lock shaft 13 is rotated by an angle, as shown in FIG. 16, the lock shaft 13 engaged with the rotor 18 is in an unlocked state in which the door can be opened by the user operating the inner handle or the outer handle.

After the worm wheel 39 is rotated by approximately 180 degrees by the motor 2, it is rotated clockwise by the bias of the spring 51, returns to the neutral position shown in FIG. 8, and enters the unlocked state.

In the super lock state,
As shown in FIGS. 13 and 17, when the inner lock knob is unlocked (1) for some reason and the user performs an operation of unlocking the door lock actuator by operating the remote controller in this state, the same as described above. The worm wheel 39 is driven by the motor 2 to approximately 180
Rotate counterclockwise (2).

At this time, the slider 34 is biased toward the first rotation position by the rotation of the knob shaft 26 as described above. Therefore, the unlocking operation portion 49 of the worm wheel 39 does not come into contact with the contact portion of the slider 34 and passes through as it is. Then, when the worm wheel 39 rotates continuously, the second cam wall surface 45 constituting the cam portion 43 is formed.
Abuts on the engaging projection 22 of the rotor 18. This allows
The engaging portion of the rotor 18 is pressed outward by the second cam wall surface 45 and rotates clockwise (3). Also,
According to the rotation of the rotor 18, the slider 3 mounted on the shaft
4 is a spring 53 according to the guide surface 31a of the non-connecting groove 31 constituting the engaging groove 29 of the knob shaft 26.
(4) counterclockwise against the urging force of. Further, with the rotation of the rotor 18, the meshed lock shaft 13 rotates counterclockwise.

Then, by the rotation of the rotor 18, the long groove 24 is connected to the connecting groove 3 of the engaging groove 29 of the knob shaft 26.
When it is equal to 0, the slider 34 is engaged with the edge of the connection groove 30 of the engagement groove 29 by the urging force of the spring 53. As a result, the rotor 18 and the knob shaft 26 are again connected integrally.

Then, the worm wheel 39 is substantially 180
When rotated, the lock shaft 13 engaged with the rotor 18 is in an unlocked state in which the door can be opened by the user operating the inner handle or the outer handle as described above. The worm wheel 39 is rotated by approximately 180 degrees by the motor 2 and then clockwise by the bias of the spring 51 to return to the neutral position shown in FIG.

When the user inserts a key into the cylinder lock and unlocks the lock in the super-locked state, first, the lock shaft 13 connected to the key shaft 12 rotates counterclockwise to the unlock position. Leads to. Then, according to the rotation of the lock shaft 13,
The rotor 18 rotates clockwise. At this time, the rotor 1
8, the slider 34 is provided with the edge of the long groove 24 and the engagement groove 2
9 and can rotate only to the side of the connecting groove 30 that forms the engaging groove 29. As a result, the knob shaft 26 is pressed by the connecting pin 37 of the slider 34,
It will rotate together with the rotor 18. Then, when rotated to the unlock position, the connection pin 37 of the slider 34 reaches the first rotation position in the connected state by the bias of the spring 53 provided on the knob shaft 26.

In the locked state shown in FIG. 9, when the user performs an operation to unlock the door lock actuator by operating the remote controller, the worm wheel 39 is driven by the motor 2 in the same manner as when the super lock is released. It rotates about 180 degrees counterclockwise (1). At this time, in the locked state, since the slider 34 is at the first rotation position, the only difference is that there is no rotation operation of the slider 34 by the unlocking operation part 49 shown in FIG. That is,
The rotor 18 is rotated by the worm wheel 39 shown in FIGS. 15 and 16 to change from the locked state to the unlocked state.

As described above, in the vehicle door lock actuator of the present invention, since the slider 34 is rotated by the super lock operation section 48 instead of the cam section 43 provided on the worm wheel 39, a super lock state is achieved. The distance between the end of the first cam wall surface 44 for locking and the super-lock operation section 48 can be freely designed. Therefore, it is possible to reliably prevent the motor 2 from going into the super lock state due to the overrun of the motor 2 even though the user has performed a normal lock operation.

Further, since the rotor 18 is provided with the elastic piece 25 for maintaining the connected or unconnected state in the long groove 24 through which the connecting pin 37 is inserted, the slider 34 is inadvertently prepared due to vibration during running or the like. The connection state or the non-connection state can be prevented from being released. Moreover, the slider 3
Since the spring 53 for urging the knob 4 toward the connected state is provided, it is possible to reliably prevent the rotor 18 and the knob shaft 26 from releasing the connected state. Further, the spring 53 urges the slider 34 to the side connecting the rotor 18 and the knob shaft 26 via the connecting pin 37 when the state is changed from the super locked state to the unlocked state. In this unlocked state, the rotor 18 and the knob shaft 26
Can be connected.

The vehicle door lock actuator of the present invention is not limited to the configuration of the above embodiment. For example, in the above embodiment, the slider 34 as the connecting member is rotatably disposed on the rotor 18 as the first rotating member. However, the slider 34 is rotatable toward the knob shaft 26 as the second rotating member. And various modifications are possible.

As is apparent from the above description, in the vehicle door lock actuator of the present invention, the cam member does not perform the lock operation and the unlock operation, but the super lock operation portion provided separately. The super-lock operation is performed by rotating the connecting member with. Therefore, the distance between the end portion of the first cam wall surface that performs the locking operation in the cam portion and the super lock operation portion can be freely designed. As a result, it is possible to reliably prevent the motor from going into the super-lock state due to the overrun of the motor despite the user performing a normal lock operation.

An elastic piece for holding the connected state or the unconnected state of the first rotating member and the second rotating member is provided on one of the rotating members on which the connecting member is rotatably arranged. Therefore, it is possible to prevent the connection member from naturally releasing the connection state or the non-connection state of the first rotation member and the second rotation member due to vibration or the like during traveling.

Further, since the urging member for urging the connecting member toward the side where the first turning member and the second turning member are connected to each other is provided, the first turning member and the second turning member are not connected for any reason. It is possible to reliably prevent the connection state with the rotating member from being released.
In addition, when the locking member is changed from the super-locked state to the unlocked state, the connecting member is urged toward the side connecting the first rotating member and the second rotating member. In this unlocked state, the first rotating member and the second rotating member can be connected.
