Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In order to reduce the closing force of the door in the automobile, the present invention closes the door to the half-latch position, which is a so-called half-door state, and thereafter forcibly moves the door lock latch to the full-latch position by the closure. , The present invention relates to a vehicle door lock closing device for completely closing a door.

[0002]

[Prior art]

 In this type of conventional door lock closing device, when the striker engages with the door lock latch as the door closes, and the latch reaches the half-latch position, the half switch operates and the closure rotates normally. When controlled, the closure's closing lever forces the latch to rotate to the full-latch position, and then when the latch reaches the full-latch position, the full switch is actuated to reverse-control the closure and to close the closure's closing lever. It is designed to return to its original position.

[0003]

[Problems to be solved by the device]

 However, in the conventional device described above, the half switch is linked to the pole that prevents the latch from moving to the open position side, the door is closed to the half latch position, and the latch is open position side. The half switch is operated by moving the pole to the release position side when the half latch position is reached from the position where the full switch is linked to the closure closing lever, and the closing lever is latched from the original position. So that it can be operated by the close lever when it is moved to the position where it can be set to the full latch position. Furthermore, as shown in FIG. 6, the half switch (101) and the full switch (102) are respectively input to the control circuit (103). Connect to the ports (103a) (103b) and input the half and full signals from each switch (101) (102) to the input ports (103a) (103b) of the control circuit (103). Because the motor (104) of the closure was controlled to rotate in the forward and reverse directions, if the mounting position of the full switch (102) was not accurately determined, the closure would reverse before it became a full latch, or it would become a full latch. Nevertheless, there was a problem that the operation timing was incorrect such that the closure did not reverse.

In particular, the closing lever of the closure is often attached later to the door lock after the work of assembling the door lock is completed. In such a case, the movement range of the closing lever and the door The timing of engagement of the lock latch and the pole is likely to vary, and even if the full switch (102) is always fixed at a fixed position, the above-mentioned deviation of the operation timing is likely to occur.

In order to eliminate such an error, if the mounting position of the full switch (102) can be finely adjusted, not only the mounting structure becomes complicated, but also the adjustment work must be performed manually. The work becomes extremely complicated.

In view of the above problems of the prior art, the present invention ensures that the closure operates with accurate timing even if there is a slight deviation in the mounting position of the switch or the dimensions of the components. It is an object of the present invention to provide a vehicle door lock closing device that can be operated.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an open position which is provided on either one of a door and a vehicle body and is completely separated from a striker provided on the other side, a half-latch position which barely engages with the striker, and a striker. A latch that can be moved to a full-latch position that completely engages with the latch, a locking position that prevents the latch from moving from the half-latch position and the full-latch position to the open position by engaging a part of the latch, and the latch. The latch can be moved to the release position that allows the movement, and when the latch reaches the half-latch position from the open position, it is moved to the release position by the latch and the latch is released. Mounted on an automobile door lock equipped with a pole that moves to the locking position side when reaching the full latch position. A chain device for forcibly moving the latch from a half-latch position to a full-latch position by a drive means, the latch reaching the half-latch position from the open position side, and the full-latch position being reached. The closure is activated by detecting that the detection means has reached the half-latch position, and the closure has been activated by detecting that the detection means has reached the full-latch position. In a vehicle door lock closing device having a control device for stopping the pole, the detecting means is linked to the pole, and when the latch reaches the half-latch position from the open position side to the release position side of the pole. Actuated by moving and actuated by moving the pole toward the locking position when the latch reaches the full latch position. When the first detection switch that can be stopped and the latch or a member that interlocks with the latch are linked, and the latch is located within a predetermined range that includes the full latch position and a slight movement range before and after the full latch position A second detection switch adapted to be actuated on the second detection switch, and the control means actuates the closure by actuating the first detection means independently, and the second detection switch is actuated. Further, the operation of the closure is stopped by stopping the operation of the first detection means.

The closure forcibly moves the latch from the half-latch position to the full-latch position, and the closure causes the close lever to move in the latch forcible movement direction by rotating in the forward direction and reversely moves the close lever to the original position. In a device provided with a motor as a driving means for returning to the above position, the control device causes the motor of the closure to rotate in the forward direction when the first detecting means is operated independently, and while the second detecting switch is operating. It is preferable that the closure motor is rotated in the reverse direction by stopping the operation of the first detection means.

In the middle range of the half-latch region from the half-latch position to the full-latch position of the latch, the pole can be reciprocated once from the release position side to the locking position side. It is preferable to limit the operating range of the detection switch to a range away from the middle range of the latch.

[0010]

[Action]

 When the door is closed, the striker engages the door lock latch, the latch reaches the half-latch position, and the pole is moved from the locked position to the released position. The 1-sensing switch is actuated, which causes the closure to be actuated, forcing the latch to pivot towards the full-latch position and closing the door. If the latch approaches the full-latch position in the meantime, the second detection switch is activated, and while the second detection switch is activated, the latch reaches the full-latch position and the pole is moved to the locking position side. Then, the movement of the pole at that time stops the operation of the first detection switch, and thereby the operation of the closure. Even if the mounting positions of the first detection switch and the second detection switch deviate to some extent, the above operation timing does not deviate.

Further, the pole engages with the half-latch engaging portion and the full-latch engaging portion of the latch (22) to rotate the latch (22) from the half-latch position and the full-latch position to the open position side. The latch (22) can be rotated to the locking position to prevent it and the release position to allow the ratchet (22) to rotate to the open position by releasing it from the latch (22). When it is located in the half-latch area (see Fig. 5) from the position to the full-latch position, it abuts the half-latch engaging part and the full-latch engaging part of the latch (22) except for the intermediate range. When the latch (22) is rotated to the release position side and the latch (22) reaches the full latch position, it is moved to the locking position side. It should be noted that while the latch (22) moves within the intermediate range of the half-latch area, the pole is moved back and forth once from the release position side to the locking position side.

Inside the door (2), in addition to the door lock (8), when the door (2) is closed to a half-latch position where it is in a half-door state, the latch (22) is forcibly rotated. , Closure (9) that forcibly closes the door (2) to the full latch position, and release lever (10) that rotates the open lever (17) fixed to the pole of the door lock (8). The pawl is released from the latch (22) by being linked through the member (11) and rotating the open lever (17) toward the release position via the release lever (10), so that the latch and striker are released. And an actuator (12) for releasing the engagement with.

The closure (9) rotates a sector gear (not shown) pivotally attached to the base plate (14) of the closure (9) by the forward rotation of the closure motor (13) to rotate the cable (15). ) To rotate the close lever (16) provided in the door lock (8) linked to the sector gear in the closing direction, and the latch (22) in the door lock (8) is moved to the half-latch position by this close lever (16). To the full-latch position, the door (2) can be forcibly closed to the full-latch position, and the reverse rotation of the closure motor (13) causes the sector gear and the close lever ( 16) can be returned to the original position and rotated. The rotation range of the close lever (16) is larger than the rotation angle required to move the latch (22) from the half latch position to the full latch position.

The door lock (8) detects the operation of the open lever (17) when the pole engages with and disengages from the latch (22), that is, the latch (22) reaches the half-latch position from the open position side. When the pole is moved to the release position side, it is activated and the latch (2
It is provided on the movement locus of the first detection switch (18) and the closing lever (16), whose operation is stopped by the movement of the pole to the locking position side when 2) reaches the full latch position. The close lever (16) moves the latch (22) toward the full latch position, moving it in the close direction so that the latch (22) is located within a predetermined range including the full latch position and a slight movement range before and after it. A second detection switch (19) is provided so that it can be activated during operation.

In this embodiment, the detection timings of the first detection switch (18) and the second detection switch (19) are as shown in FIG. That is, the first detection switch (18) is activated (OFF) in the half-latch region (excluding the intermediate range) of the latch (22) and is inactivated (ON) in the other regions. The second detection switch (19) operates (ON) at an appropriate timing after the ratch (22) has passed the intermediate range in the half-latch region, and the latch (22) exceeds the full-latch position to cause overstroke. It becomes inoperative (OFF) in the middle of the full latch area.

(20) is a control circuit provided on the vehicle body side for controlling the door moving device (4) according to each situation, and (21) is a door side for controlling the closure (9) according to each situation. As shown in FIG. 1, the control circuit provided in the control circuit (21) has a first detection switch after power is supplied from the vehicle body (1) side to the door (2) side to the input port (21a). The first detection switch (18) is connected so that the half latch detection signal when (18) is first turned off (OFF) is input, and the input port (21b) of the control circuit (21) is also connected. The first detection switch (18) and the second detection switch (18) and the second detection switch (19) are connected to the first detection switch (18) and the first detection switch (18) so that the full latch detection signal is input when both are turned on. 2 Detection switch (19) is connected in series.

When the first detection switch (18) is first turned off and the half-latch detection signal is input to the input port (21a), the control device (21) normally rotates the closure motor (13). When the first detection switch (18) and the second detection switch (19) are both turned on and the full latch detection signal is input to the input port (21b), the closure motor (13) is reversely controlled. It is configured as follows. Therefore, the mounting position of the second detection switch (19) need only be adjusted so that the full latch position of the latch (22) is within the operating range, and the mounting position thereof is not required to be accurately adjusted.

By the closing operation of the door, the striker engages with the latch (22) of the door lock (8), the latch (22) reaches the half-latch position, and the pole is moved from the locking position to the release position side. Then, the movement of the pole at that time activates the first detection switch (18), that is, the first detection switch (18) is turned off, and the half signal is input to the input port (21a). As a result, the closure motor (13) is driven in the normal direction, and the latch (22) is forcibly rotated in the full-latch position direction via the sector gear, cable (15), and close lever (16). .

While the latch (22) passes through the middle range of the half-latch area, the first detection switch (18) turns on once and then turns off again. At this time, the closure motor (13) Since the normal rotation continues, the ON / OFF of the first detection switch (18) at this time does not affect the operation of the closure motor (13).

When the latch (22) approaches the full latch position, the operation of the close lever (16) is detected by the second detection switch (19) and turned on. In this state, when the latch (22) further rotates to reach the full latch position and the first detection switch (18) is turned on, the full latch detection signal is immediately input to the input port (21b), The closure motor (13) is driven in reverse, and the closing lever (16) and the sector gear of the closure (9) are returned to their original positions and stopped.

In the above embodiment, the closure (9) is rotated forward by the closure motor (13) to rotate the close lever (16) in the closing direction, and the first detection switch (18) and the first detection switch (18) are rotated. By detecting the full-latch state by the detection means consisting of the 2 detection switch (19), the closure motor (13) is rotated in the reverse direction and the close lever (16) is returned to the original position. , The closure (9) to the closing lever (1
6) When the full-latch state is detected by the detection means, if 6) can be automatically returned by a spring or the type in which the close lever is always continuously rotated in the closing direction is used. Alternatively, the closure may be stopped immediately.

[Effect of device]

According to the present invention, the following effects can be achieved. (A) The first detection switch is linked to the pole, and the half-latch position and the full-latch position are detected by the movement of the pole. ), The operation of the closure is stopped before the pole is completely engaged with the latch, or the operation of the closure is not stopped even though the pole is completely engaged with the latch. Does not occur.

(B) Since the first detection switch may be operated at any position within a relatively wide movement range between the locking position and the releasing position of the pole, the mounting position of the first detection switch It is not necessary to adjust the position precisely.

(C) Since the second detection switch only needs to have the full latch position of the latch within the operating range, it is not necessary to accurately determine the timing of starting and stopping the operation.

(D) Therefore, it is not necessary to accurately adjust the mounting positions of both the first and second detection switches, and even if there is a slight deviation in the mounting positions or the dimensions of the components, a malfunction occurs. The closure can be operated with correct timing without causing
