Abstract

(57) [Summary] [Purpose] To enable the locking / unlocking lever of the door lock device to be reliably moved to the locking / unlocking position even if there is some deviation in the mounting position or dimensional error. [Composition] When the motor rotates by electric operation and the reduction mechanism (4) rotates, the operating lever (6) and the output lever
(9) is moved to the locked or unlocked position. At this time, if there is a slight deviation in the positional relationship or dimensions between the actuator device and the door lock device, the locking / unlocking lever abuts the stopper before the operating lever (6) moves to the locking or unlocking position. And the output lever (9) is stopped accordingly, only the operating lever (6) rotates independently against the frictional engagement force of the position adjusting mechanisms (7a) and (10b). As a result, the positional relationship between the operating lever (6) and the output lever (9) changes, and the position of the output lever (9) is adjusted at this point.

[Industrial applications]

 The present invention relates to a deceleration mechanism that is normally and reversely rotated from a neutral position by a motor, an operating lever that is moved to a locking position and an unlocking position by rotation of a reduction mechanism, and an operating lever that is connected to an unlocking lever of a door lock. The present invention relates to a door lock actuator device having an output lever that is moved to a locked position and an unlocked position by a lever.

[0002]

[Prior Art]

 As a conventional door lock actuator device as described above, for example, there is one disclosed in JP-A-60-144479. In this device, the pin of the intermediate reduction gear engages and moves in the drive groove of the swinging member by rotating the intermediate reduction gear almost one turn by the motor, and thereby the pin is fixed to the shaft portion of the swinging member. The actuating lever is moved to the locking position and the unlocking position according to the movement amount of the pin, and the locking and unlocking lever of the door lock device is moved to the locking position and the unlocking position.

[0003]

[Problems to be solved by the device]

 However, in the conventional device described above, the pins cannot be moved in the drive groove because they interfere with the drive groove due to variations in the mounting positions of the door lock device and the actuator or the lengths of the connecting members. The operating stroke of the actuator operating lever must be set smaller than the operating stroke of the locking and unlocking lever. Therefore, when the variation in the mounting state is the worst, there is a problem that the locking / unlocking lever cannot be moved to the regular locking / unlocking position.

In view of the above problems of the prior art, the present invention ensures that the locking / unlocking lever of the door lock device is locked and unlocked even if there is some deviation in the mounting position or dimensional error. An object of the present invention is to provide an actuator device for a door lock that can be moved to a lock position.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a motor capable of rotating in the normal and reverse directions, a reduction mechanism for rotating the motor from the neutral position in the forward and reverse directions, and an operation for moving the locking mechanism and the unlocking position by rotation of the reduction mechanism. A door lock actuator device comprising a lever and an output lever which is connected to a locking / unlocking lever of a door lock whose movement range is limited by a stopper and which is moved to a locking position and an unlocking position by an operating lever, It is characterized in that the actuating lever and the output lever are connected to each other via a position adjusting mechanism that couples both levers by frictional contact.

[0006]

[Action]

 When the motor is rotated by the electric operation and the reduction mechanism is rotated, the operating lever and the output lever are moved to the locked or unlocked position. At that time, if there are variations in the positional relationship between the actuator device and the door lock device or the length of the linking member, etc., before the operating lever moves to the locked or unlocked position due to the rotation of the reduction mechanism. , The locking / unlocking lever comes into contact with the stopper and stops, and the output lever is stopped accordingly, so that only the actuating lever rotates independently against the frictional engagement force of the position adjustment mechanism. The positional relationship between the operating lever and the output lever changes, and the position of the output lever is adjusted at this point.

 An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 3, (1) is a motor capable of rotating in the forward and reverse directions housed in a housing composed of a cover (2) and a case (3), and (4) is attached to the case (3) by a shaft (5). A worm wheel that is pivotally mounted and meshes with a worm (1a) that rotates integrally with the rotating shaft of the motor (1) to form a reduction mechanism that can rotate in forward and reverse directions. ) Is formed so that it can rotate forward and backward from the neutral position shown in FIG.

Reference numeral (6) is an actuating lever which is formed of an elastically deformable synthetic resin material and pivotally attached to the housing by a shaft portion (7) formed on the base portion so as to be swingable. On a side surface that overlaps with one side surface, a coupling groove (8) with which the engagement portion (4a) is movably engaged is provided, and the engagement portion (8) is rotated by electric operation to rotate the worm wheel (4). By the movement of 4a), the stroke equivalent to the stroke corresponding to the operation stroke of the locking and unlocking lever can be moved, and it can be moved to the locking position shown by the solid line and the unlocking position shown by the two-dot chain line in FIG. You can The linkage groove (8) has an arc-shaped idle groove portion (8a) having a length corresponding to the operation stroke of the locking / unlocking lever of the door lock device (11) about the shaft (7), and the idle groove portion (8a). 8a) has an engaging groove portion (8b) extending from the center in the radial direction, and is formed in a substantially Y shape.

A plurality of knurls (7a) forming a part of the position adjusting mechanism are formed on the outer peripheral surface of the shaft portion (7), and the case (2) is formed at one end of the shaft portion (7). A bearing hole (7b) into which the formed protrusion (2a) is rotatably fitted is provided as a recess. At the other end of the shaft portion (7), there is a split groove (7c) extending in the axial direction so that the other end side of the shaft portion (7) can be elastically deformed in a diameter reducing direction, and an engaging claw (7d). And are formed.

(9) has a cylindrical coupling part (10) formed at the base, and the coupling part (10) is fitted onto the shaft part (7) so that it swings to the housing together with the operating lever (6). The movable output lever is connected to the connecting part (9a) formed at the tip of the lock lever (not shown) of the door lock device (11) via a connecting member (12) such as a rod. The locking lever is moved to the locking position shown by the solid line in FIG. 1 and the unlocking position shown by the chain double-dashed line in conjunction with the movement of the locking / unlocking lever to the locking position and the unlocking position, and the operating lever (6) At the same time, it moves the operating stroke corresponding to the operating stroke of the locking / unlocking lever. The locking / unlocking lever of the door lock device (11) can move the operating stroke between the locking position that disables the unlocking operation of the door lock device (11) and the unlocking position that enables the unlocking operation. By contacting each stopper (not shown) formed in the door lock device, the door lock device is stopped at the locking position and the unlocking position.

The connecting portion (10) is formed of an elastically deformable synthetic resin material, and has a hole (10a) and a knurl (10b) forming a part of a position adjusting mechanism at the base and inner circumference thereof. And are formed. The coupling part (10) elastically deforms the other end side of the shaft part (7) by the split groove (7c) to fit the shaft part (7) into the hole part (10a), and the engaging claw (7d). By engaging with the end surface of the coupling portion (10), it is fitted onto the shaft portion (7) of the operating lever (6) so as not to come off. The knurling (10b) is formed inside the coupling part (10) and comes into frictional contact with the knurling (7a) on the shaft part (7) side, and the operating lever (6) and the output lever (9). And are combined so that they rotate as a unit. That is, the shaft portion (7) of the operating lever (6) and the coupling portion (10) of the output lever (9) are coupled via the position adjusting mechanism by frictional contact of the respective knurls (7a) and (10b). To be done. The coupling force between the knurling (7a) on the shaft (7) side and the knurling (10b) on the coupling part (10) is stronger than the force to move the locking and unlocking lever to the locking and unlocking position, and more. By applying the force of, the engagement positions of the lowlets (7a) and (10b) are displaced from each other, and the shaft lever (7) serves as a fulcrum to actuate the operating lever (6) and the output lever (9). They are connected by a force that can change the positional relationship. The coupling force is determined by the elastic deformation of the split groove (7c) on the other end side of the shaft portion (7) and the elastic deformation of the coupling portion (10).

From the neutral position in which the engaging portion (4a) of the worm wheel (4) is located in the idle groove portion (8a), the worm wheel (4) is normally or reversely rotated by electric operation, so that 2, the engaging portion (4a) enters the engaging groove portion (8b) of the connecting groove (8) and engages with each other, so that the operating lever (6) is locked by a solid line or a two-dot chain line. The output lever (9) can be moved to the locked position shown by a solid line and the unlocked position shown by a chain double-dashed line together with the operating lever (6) through the position adjusting mechanism while moving to the position or the release position. ..

(13) is a neutral detection switch provided between the worm wheel (4) and the case (3), and detects the neutral position of the worm wheel (4) to the motor (1). The worm wheel (4) is stopped at the neutral position by stopping the power supply to the worm wheel (4).

Next, the operation of the embodiment of the present invention will be described. 1, the worm wheel (4) is in the neutral position, and the engaging portion (4a) is located at one end of the idle groove portion (8a) of the linking groove (8) of the operating lever (6). In this state, by unlocking the manual lock knob connected to the locking / unlocking lever, the output lever (9) and the actuation are activated via the locking / unlocking lever of the door lock device (11) and the rod (12). The lever (6) moves from the locked position shown by the solid line in FIG. 1 to the unlocked position shown by the chain double-dashed line, and the engaging part (4a) relatively moves the empty groove part (8a) of the linking groove (8). From one end to the other. In addition, when the operating lever (6) and the output lever (9) are in the unlocked position and the lock knob is locked and operated, the engaging portion (4a) is moved from the other end of the idle swing groove portion (8a) to one end. By moving relatively, the output lever (9) and the operating lever (6) respectively move to the locking position. Therefore, the manual operation can be performed lightly without reversing the speed reducing mechanism.

When the operating switch inside or outside the vehicle is electrically unlocked from the locked state shown by the solid line in FIG. 1, the motor (1) rotates normally and the worm wheel (4) rotates counterclockwise. To do. The rotation of the worm wheel (4) causes the engaging portion (4a) to enter and engage with the engaging groove (8b) as shown by the chain double-dashed line in FIG. The output lever (9) moves to the unlocked position. At that time, if the positional relationship between the actuator device and the door locking device (11) or the length of the linking member (12) varies, the worm wheel (4) is rotated to rotate the operating lever (6). ) Has moved to the unlocking position, the locking / unlocking lever has already contacted the stopper and has already moved to the unlocking position, so that the worm wheel (4) cannot rotate any further. There is a possibility that However, in the present embodiment, in this state, only the actuating lever (6) and the knurl (7a) of the shaft portion (7) and the connecting portion (10) are kept in the unlocked position of the output lever (9). By rotating to the normal unlocked position against the coupling force with the knurl (10b), the positional relationship between the operating lever (6) and the output lever (9) changes, and the output at this point The position of the lever (9) is adjusted with respect to the locking / unlocking lever by the position adjusting mechanism.

Then, the worm wheel (4) continues to rotate further, and the engaging portion (4a) again enters into the idle groove portion (8a), so that the worm wheel (4) reaches the neutral position. The neutral detection switch (13) detects the neutral position, stops the power supply to the motor (1), and stops the worm wheel (4) at the neutral position. Therefore, once electrically operated, the positional relationship between the operating lever (6) and the output lever (9) is automatically adjusted, and the positions of the output lever (9) and the locking / unlocking lever are adjusted. After that, the positional relationship between the operating lever (6) and the output lever (9) does not change.

When the electric locking operation is performed from the unlocked state shown by the chain double-dashed line in FIG. 1, the motor (1) reversely rotates and the worm wheel (4) rotates clockwise. The rotation of the worm wheel (4) causes the engaging portion (4a) to enter and engage with the engaging groove (8b) as shown by the solid line in FIG. (9) moves to the locked position. In this case, the positional relationship between the operating lever (6) and the output lever (9) is adjusted by the above-mentioned electric operation, and the position adjustment between the output lever (9) and the locking / unlocking lever has already been performed. When the operating lever (6) is moved to the locking position, the locking / unlocking lever is moved to the locking position by the movement of the output lever (9).

After that, when the worm wheel (4) further rotates and the engaging portion (4a) again enters the idle groove (8b) and the worm wheel (4) reaches the neutral position, the neutral detection switch ( 13) detects the neutral position and the worm wheel (3) stops at the neutral position. Therefore, the operating stroke of the electric output lever (9) and the operating stroke of the locking / unlocking lever of the door lock device (11) can be set to the same, so that the actuator device and the door lock device (11) can be attached. Even if the position or the length of the connecting member (12) varies, the variation (10) between the knurl (7a) on the shaft (7) side of the operating lever (6) and the output lever (9) should be taken into account. The position is adjusted with the knurl (10b) on the) side, and the locking / unlocking lever can be reliably moved to the regular locking position or the unlocking position. Also, when the output lever (9) reaches the locking position, the locking / unlocking lever moves to the locking position, so there is no need to strongly abut the locking / unlocking lever on the stopper. Can reduce the impact on.
