Description

TECHNICAL FIELD The present invention relates to a control device of a door lock device for controlling a door lock device used for locking a door of a vehicle to a locked state and an unlocked state.

"Prior Art and its Problems" As a control device of this kind, the one shown in FIG. 6 has been conventionally proposed. For example, on a base 1 having a striker fixed to the vehicle body side, a lock release lever 2 interlocking with a door lock device fixed to the other side such as a lid is provided.
And the opener lever 3 that works with the unlock handle
And are coaxially pivoted on a common shaft 4 and are relatively rotatable. A torsion spring 9 is attached to the common shaft 4, one end of which is attached to the base 1 side and the other end of which is hooked to an engagement piece 5 that engages with the lock release lever 2 of the opener lever 3. Therefore, the opener lever 3 is urged to rotate in the clockwise direction by the torsion spring 9, and the engaging piece 3a
The rotation is restricted by. A control pin 5 is slidably fitted in the elongated guide hole 2a of the lock release lever 2, and one end of the control pin 5 is fitted in an L-shaped bending interlocking hole 6. The bending interlocking hole 6 includes an interlocking portion 6a and a relief portion 6b. Therefore, the lock release lever 2 rotates in the same direction as the opener lever 3 rotates in the counterclockwise direction when the control pin 5 is located in the interlocking portion 6a. The counterclockwise rotation of the lock release lever 2 is the lock release direction.

On the other hand, on the base 1, a locking lever 7 for switching the control pin 5 between a locked position and an unlocked position by a manual key device, an electrode solenoid or the like.
Is rotatably mounted on a shaft 7a. The lock position is
The position where the control pin 5 fits into the escape hole 6b of the interlocking bending hole 6 and the unlock position are the positions where the pin 5 fits into the interlocking portion 6a.

Therefore, according to this control device, when the opener lever 3 is rotated in the unlocking direction while the locking lever 7 is being rotated to the unlock position, the lock releasing lever 2 moves in the same direction integrally with the opener lever 3. Rotate to unlock the door lock device. On the other hand, when the locking lever 7 is set to the lock position, only the opener lever 3 swings and swings, and the unlock handle 2 does not move, and therefore, the locked state of the door lock device is maintained.

By the way, as shown in FIG. 7, the lock release lever 2 and the opener lever 3 pivotally mounted on the base 1 so as to be rotatable relative to each other by the common shaft 4 are in contact with each other at the hinge portion, and the opener lever 3 is If the contact portion twisting force is generated during the idling rotation of the door, the lock release lever 2 is also rotated together with the door even if the contact portion is locked, and the door lock device is unlocked.

Therefore, in the conventional device, another spring 8 is bridged between the lock release lever 2 side and the base 1 side, and this spring 8 prevents the lock release lever 2 from rotating in the lock release direction.

However, if the spring 8 as a separate body is separately provided, it is mechanically large and complicated, which causes a cost increase.

Therefore, in the present invention, without using the assisting force of the spring,
An object of the present invention is to obtain a control device for a door lock device, which can surely prevent the unlocking lever from rotating in the unlocking direction when the opener lever swings and swings, and which is mechanically simple.

[Outline of the Invention] In the present invention that achieves the above object, the lock release lever is slidably provided with a restriction pin that moves in conjunction with the rotation of the locking lever to the lock rotation position and the unlock rotation position. The base is provided with a restriction protrusion that engages with the restriction pin when the locking lever is in the lock rotation position to prevent the lock release lever from rotating in the lock release direction.

"Embodiment of the Invention" Hereinafter, the present invention will be described with reference to illustrated embodiments. Base 1
A striker 1 is fixed to the vehicle body side, for example.
It is equipped with 4. A lock release lever 21 and an opener lever 31 below the lock release lever 21 are coaxially and relatively pivotably mounted on the base 11 by a common shaft 12.

A torsion spring 17 is attached to the common shaft 12. The torsion spring 17 is hooked to the rotation restricting piece 16 having one end thereof erected on the base 11 and the other end of the spring hooking piece 35 erected on the side of the opener lever 31, respectively. A counterclockwise rotation biasing force in FIG. 1 is applied.

The lock release lever 21 is formed to extend at a substantially right angle around the common shaft 12, and has a lock release arm 22 and a pin guide arm 23. The lock release arm 22 is interlocked with a door lock device (not shown), and unlocks the lock state of the door lock device with respect to the striker 14 by rotating the lock release lever 21 in the lock release direction (clockwise direction in the figure). Is. In addition, the pin guide arm 23
Has a guide notch 23a extending in the left-right direction in FIG. 1, and the guide pin notch 23a has a restriction pin 51 in the guide notch 23a.
Is slidably fitted. The lock release lever 21 is restricted in its counterclockwise rotation end by a rotation restricting piece 15 formed upright on the base 11.

The opener lever 31 is connected to a lock release handle (not shown) via a wire W and interlocks with the operation of the lock release handle, and has a pin engagement arm 32, a rotation restricting arm 33, and a rotation restricting piece 34. . The pin engagement arm 32 is engageable with the restriction pin 51 which is slidable in the guide notch 23a, and when the restriction pin 51 is located at the engagement position with the restriction pin 51, the lock release lever is released via the restriction pin 51. 21 and the opener lever 3
The rotation of the lock release lever 21 in the lock release direction (clockwise) causes the lock release lever 21 to rotate in the same direction. Further, when the restriction pin 51 is located at the non-engagement position with the pin engagement arm 32, only the opener lever 31 alone idles and rotates in the unlocking direction. The rotation restricting arm 33 is engageable with the spring hooking piece 16 and restricts the clockwise rotation of the opener lever 31. The rotation restricting piece 34 is engageable with the lock releasing arm 22 of the lock releasing lever 21 and restricts the counterclockwise rotation of the opener lever 31.

Further, a locking lever 41 is pivotally attached to another position on the base 11 by a shaft 13. This locking lever 41 is manually operated via the rotation operation unit 42.
Alternatively, it is rotated in conjunction with the operation of a key device (not shown), and the conversion hole 43 into which the regulation pin 51 is fitted and the base 1
1. The recessed portion 4 engageable with the rotation restricting piece 18 formed upright
Have four. The conversion hole 43 slides the restriction pin 51 between an engagement position (unlocked position) and a non-engaged position (locked position) with the pin engagement arm 32, and also opens the restriction pin 51 at the unlocked position. The restriction pin 51 is released when the lever 31 and the lock release lever 21 are integrally rotated, and is formed in an arc shape around the common shaft 12. The recess 44 engages with the rotation restricting piece 18 and restricts the rotation angle of the locking lever 41. Therefore,
The locking lever 41 rotates to move the restriction pin 51 between the unlock position and the lock position within the restricted rotation angle. The locking lever 4
A spring 45 is provided between 1 and the base 11.
The spring 45 biases the locking lever 41 in reverse to both rotation restricting positions according to the rotation direction.

A restricting protrusion 52 is formed on the base 11 to engage with the restricting pin 51 in the locked position. The restriction protrusion 52 engages with the restriction pin 51 to prevent the lock release lever 21 from rotating in the lock release direction when the opener lever 31 swings freely in the lock position.

As described above, when the restriction pin 51 is in the non-engagement position with the pin engagement arm 32, the opener lever 31 does not rotate the lock release lever 21 in the lock release direction, but independently swings and rotates. Opener lever 31
Since the hinge is in contact with the lock release lever 21, the opener lever 31 that should rotate by idling by the frictional force generated between the lock release lever 21 and the lock release lever 2
1 may also be rotated in the unlocking direction. Therefore, in the present invention, the regulation pin 51 in the locked position is attached to the regulation projection 5
2 to restrict the movement of the lock release lever 21 to prevent the lock release lever 21 from rotating due to frictional force.
It is possible to surely perform the idling rotation of 1. In the embodiment, the regulation projection 52 is formed by bulging the base 11 in a trapezoidal shape, but it may be formed so as to engage with the regulation pin 51 by cutting and raising a part of the base 11.

The device having the above structure operates as follows. First, when the locking lever 41 in the lock position is rotated to the unlock position, the regulation pin 51 moves to the engagement position with the pin engagement arm 32, and the opener lever 31 and the lock release lever 21 move the regulation pin. It becomes possible to interlock with 51. When the lock release handle (not shown) is operated, the opener lever 31 is rotated in the lock release direction (clockwise) in conjunction with this, and the lock release lever 2
1 is rotated integrally in the same direction. As a result, the lock release arm 22 interlocks with a door lock device (not shown), the striker 14 held by the hook of the door lock device is released, and the locked state is released.

On the other hand, when the locking lever 41 is rotated to the lock position and the regulation pin 51 is moved to the non-engagement position with the pin engagement arm 32, the interlocked state of the opener lever 31 and the lock release lever 21 is released. . At this time, the restriction pin 51 engages with the restriction protrusion 52. The opener lever 31 is now in the locked state, and even if the lock release handle is operated, the opener lever 31 only rotates clockwise in an idle motion, and the lock release lever 21 does not rotate in the lock release direction. Therefore, the opener lever 31 does not rotate. Only the lever 31 swings freely. Here, even if a frictional force is generated at the hinge portion where the opener lever 31 and the lock release lever 21 come into contact with each other and the frictional force tries to rotate the lock release lever 21, the regulation pin 51 engages with the regulation projection 52. Then, the rotation of the lock release lever 21 in the lock release direction is mechanically blocked. Therefore, no malfunction occurs in the lock release lever 21, and the opener lever 31 surely swings idly to maintain the locked state. A door closing detection lever 53 pushes a door closing detection switch 56 when the pressed portion 54 is pushed to rotate about a shaft 55 when the door is closed.

[Advantage of Invention] As described above, according to the present invention, when the opener lever is idly rotated at the locking position of the locking lever, the restricting pin engages with the restricting projection to unlock the unlocking lever. Is prevented from turning. Therefore, even if a frictional force acts between the opener lever and the lock release lever, the opener lever can surely swing and rotate, and the malfunction of the lock release lever can be prevented. Also,
To prevent the incorrect rotation of the lock release lever when locked,
Since only the engagement between the regulation pin and the regulation projection is performed, the mechanism is simplified.
