Next, the operation of the above embodiment will be described with reference to the circuit diagram of FIG.

In Fig. 3, (R1), (R2), (R3), (R4),
(R5) is a relay, (r1), (r2-1), (r2-2),
(R3), (r4), (r5-1) and (r5-2) are their contact points, (46) is a delay timer and (46a) and (46b).
Is a contact point of the actuator, and (47) is an actuator for automatically locking / unlocking the locking / unlocking operation device such as the knob (7) by operating the operation device (49) connected to the power source (48). Indicates. Other reference numerals electrically indicate the above-mentioned members.

When the slide door (1) is closed to a predetermined position and the power supply switch (32) is automatically turned on by the slide door (1), the relay (R1) provided in the controller (30) is energized, Power is supplied from the battery (31) to the connector (12) on the vehicle body (2) side by closing the contact (r1).

When the sliding door (1) reaches the half-latch position immediately before, the contact (14a) of the moving shaft (14) in the connector (11) on the sliding door (1) side moves to the moving shaft (2) on the vehicle body (2) side.
The contact (26a) of 6) is contacted, and at that moment, power supply from the vehicle body (2) side to the slide door (1) side is started.

From this state, the door (1) is further closed slightly, and when the latch in the door lock device (3) and the striker (both not shown) on the vehicle body side barely engage with each other, that is, the sliding door. When (1) is in the half-door state, the rear end of the moving shaft (14) recessed in the rear comes into contact with the movable contact (21) of the half-latch detection switch (17), resulting in half-latch. Is sent to the controller (9) provided on the door (1).

When the half-latch detection switch (17) is activated, the relay (R3) and the timer contact (46a) in the relay (R3) connected in series with the half-latch detection switch (17) are normally closed to cause the relay (R3) to operate.
2) is energized, and the contact (r2-2) is closed, so that the timer (46) is also energized.

The timer (46) has begun to measure a fixed time (for example, 5 seconds) from this time.

At the same time as energizing the relay (R2), its movable contact (r2-
1) is switched to the normally open side, and the motor (35) in the closure (8) is rotationally driven in one direction.

When the motor (35) rotates, the drive gear (36) is rotated clockwise in FIG. 1 via a reduction mechanism (not shown), and the sector gear (37) meshing with the drive gear (36) rotates the shaft (3
It is rotated counterclockwise from the original position to the front limit position around 8).

When the sector gear (37) rotates, a drive lever (39) integral with the sector gear (37) holds a close lever (41) pivotally attached to a bracket (40) of the door lock device (3) with a wire (42). Rotate counterclockwise in plan view.

As a result, the latch in the half-latch position is forced to rotate by contacting the one arm of the close lever (41) with the protruding lever (43) that is integrally provided with the latch and is rotated. Then, the sliding door (1) which has been in the half-door state is completely closed.

When the latch is in the full rat position, the close lever (4
The other arm of 1) comes into contact with the full-latch switch (44) provided on the bracket (40) to close it, and the relay (R3) is energized so that it is on the normally closed side until then. The contact (r3) is switched to the normally open side to hold the relay (R3) by itself and open the normally closed side to restore the contact (r2-1) in the relay (R2) to the normally closed side. Stop the motor (35).

At this time, the contacts of the limit switch (45) provided behind the sector gear (37) are already closed when the sector gear (37) is disengaged from the original position, so the full latch switch (44). The relay (R4) is actuated at the same time as is closed, and the motor (35) is rotated in the direction opposite to the above by the actuation of the movable contact (r4) to the normally open side. As a result, the sector gear (37) is rotated clockwise, and when it returns to its original position, the limit switch (45) is turned off and the movable contact (r4) of the relay (R4) is normally closed. The motor (35) is stopped immediately after the return of.

When the contact (r3) is switched to the normally open side by the operation of the relay (R3) and self-maintained,
That is, when the relay (R2) is de-energized and the contact (r2-2) of the relay (R2) is opened, its operation is stopped, and the timing until then is stopped. Therefore, the timer (4
6) never works.

Further, even when the slide door (1) is closed to the full latch position at once without passing through the half latch position, the same series of operations as described above is performed, but the timer (46) is energized in the same manner as above. Since the contact (r3) is disconnected when switched, there is no possibility that the timer (46) will operate and the motor (35), actuator (47), etc. will operate thereafter.

By the way, the above-described series of operations is performed by the timer (46) without any obstacle between the slide door (1) and the vehicle body (2).
This is the case where the door (1) is normally closed from the half-latch position to the full-latch position within a certain time (for example, within 5 seconds) before the operation of, by any chance, during the door (1),
If your fingers (or other foreign objects) are caught in the door (1) and the door (1) does not reach the full latch position after a certain period of time,
Immediately after the half-latch detection switch (17) is activated, that is, when the relay (R2) is energized, the timer (4
6) operates to switch the contact (46a) to the normally open side and close the contact (46b).

At this time, the power to the relay (R2) is cut off and the contact (r2
Although -2) is opened, the timer (46) is continuously energized by closing the contact (46b), so that the contact (46a) is self-held on the normally open side.

At the same time that the relay (R2) is de-energized, the movable contact (r2-1), which has been normally open and rotating the motor (35) in one direction, returns to normally closed. Then immediately stop the motor (35).

When the motor (35) is stopped, the relay (R
4) operates and the contact (r4) is switched, the motor (35)
Is reversed.

As a result, the sector gear (37) is returned to the original position, and at the same time, the sliding door (1) immediately stops the door closing operation and returns to the half-latch position, allowing the door to be opened manually.

At this time, if the locking / unlocking operation device such as the knob (7) is locked, the relay (R5) is energized at the same time as the timer (46) is activated, and the contacts (r5-1) and (r5-2) are turned on. When both are switched to the normally open side, the actuator (47) is operated, and the locking / unlocking operation device in the locked state automatically unlocks.

Therefore, the door (1) returned to the half-latched position can be opened without unlocking the key operation from the outside or the knob operation from the inside of the vehicle.

In this embodiment, if the relay (R5) is provided in parallel with either or both of the lamp (50) and the buzzer (51) as shown by the chain double-dashed line, the timer (46) operates. At the same time, a warning can be issued by light, sound, or both.

Further, as shown by the chain double-dashed line in FIG. 3, the reversing switch (52) which is linked to the outside handle (5) or the inside handle (not shown) and which is activated by the operation in the door opening direction, Contact (46a) of the timer (46)
It may be provided in parallel with. In this way, if the timer (46) does not operate due to a failure or the like, the reversing switch (52) can be operated to reverse the motor (35), which further enhances safety.

As described above, in the above embodiment, the timer (46)
Alternatively, by operating the reversing switch (52), the door closing operation can be stopped and the door (1) can be returned to the half-latch position again. Therefore, for example, when the door (1) is stopped at wind pressure or on a slope. Due to the weight of the door when you are
Contrary to the driver's will, it is closed to the half-latch position,
In such a case, it is possible to prevent danger in the case where fingers and other foreign substances are mistakenly caught between the door and the vehicle body.

The present invention can be applied to a swinging door, a back door, a trunk lid, and the like, in addition to the slide door.

〔The invention's effect〕

According to the present invention, the door is closed to the half-latch position against the driver's intention, for example, and in such a case, a finger or other foreign matter is erroneously caught between the door and the vehicle body. If the door is not completely closed between the fully latched states, even if you do not know the operation of the closure,
Since the door closing operation is automatically stopped by the operation of the timer, the safety is extremely high, and it is possible to prevent the waste of electric power, the overload on the motor, the damage to the door and the vehicle body, etc. due to the continuous operation of the driving means. it can.
