Description

[Detailed description of the invention] The present invention relates to a remote control device for locking an opening/closing body of an automobile, and in particular, a lock that allows the trunk lid or tailgate to be unlocked by remote control from the driver's seat, etc. It relates to a remote control device.

As a conventional device of this type, there is a device as shown in FIGS. 1 and 2.

This device is designed to remotely control the lock of the tailgate of a car, and when the tailgate is closed, the striker Rotate the open lever d pivotally mounted on the base plate C of b in the clockwise direction in FIG. One end f is moved to the right in FIG. 1, thereby rotating the locking plate g in the counterclockwise direction in FIG. The tailgate can now be opened by releasing the lock.

However, in such a conventional device, as shown in Fig. 2, if the tailgate is closed due to an incorrect operation or a malfunction, etc., with the open lever d being pulled by the cable a, Lock body e provided on the tailgate side
One end f of the locking plate g that protrudes further comes into contact with the free end of the open lever d, and there is a risk that the open lever d or the locking plate g will break.

As such a conventional technique, there is Japanese Utility Model Publication No. 46-22331.

The purpose of this invention is to provide a remote control device for a door lock that eliminates the risk of breakage of the open lever or locking plate due to such erroneous operation or malfunction, and enables safe and reliable operation. The following description will be given based on the embodiments shown in FIGS. 3 to 6.

A is a lock body provided on the tailgate side of an automobile, and B is a striker provided on the vehicle body side.

The lock body A includes a cover plate 2 in which an entry port 1 for a striker B is bored.

Inside this cover plate 2, a striker B is installed at the entrance 1.
A two-pronged latch 3 that engages with the striker B when the latch enters the interior, and a locking plate 4 that locks the latch 3 with this latch engaged with the striker B, They are each pivoted with .

At the rear end of the latch 3 and the rear end of the locking plate 4,
Each end of a tension coil spring 7 extending in the left and right direction is locked, and the urging force of the spring 7 causes the latch 3 to move in the direction in which the striker B is pulled out from the entrance 1, that is, in the third direction.
The locking plate 4 is biased counterclockwise in the figure, and the locking plate 4 is biased in a direction to lock the latch 3, that is, clockwise in FIG. 3.

Further, the locking plate 4 is connected to an operation bundle (not shown) provided on the tailgate via an appropriate rod (not shown).
With this operation bundle, the knocking plate 4 can be rotated counterclockwise in FIG. 3 to release the latch 3.

An unlatch lever 9 that projects outward from the cover plate 2 through a window hole 8 formed in the cover plate 2 is connected to one end of the locking plate 4.

This unlatch lever 9 can be in a locked state as shown in FIG. 3, in which the locking plate 4 locks the latch 3 in an engaged state with the striker B, and in a locked state as shown in FIG. It can be moved to a release position such as

Striker B has a base plate 10 fixed to the vehicle body.
A bracket 11 extending upward in a stepped manner toward the left is provided on the top, and an open lever 13 is pivotally mounted with a shaft 12 below the upper horizontal piece 11a.

A coil spring 14 is wound around the shaft 12 between the enlarged diameter portion 12 a of the shaft 12 and the open lever 13 .

One extending end of this coiled spring 14 is attached to the bracket 11
The hanging piece 11b hanging down from the rear edge of the upper horizontal piece 11a and the other extending end are respectively locked on the front left edge of the open lever 13. It is biased counterclockwise in Figure 3.

A downward projecting piece 13a in the shape of a dovetail is connected to the front left edge of the open lever 13, and one end of the downward projecting piece 13a is attached to a remote control bundle (not shown) installed in the driver's seat or the like. The other end of the connected cable 15 is fixed.

Thus, the open lever 13 is in an inoperative position as shown in FIG. 3, in which the upward protruding piece 13b connected to the front right edge thereof is in contact with the front edge of the upper horizontal piece 11a of the bracket 11; From that state, the cable 1 is controlled by the remote control bundle.
By pulling 5, it can be rotated to the release position as shown in FIGS. 5 and 6, which is rotated by a required angle clockwise in FIG. 3.

A release lever 17 is pivotally attached to one end of the open lever 13 with a shaft 16.

The relief lever 17 is attached counterclockwise in FIG. 3 by a coil spring 18 that tensions each end of the relief lever 17 by a protrusion 17a bent upward at its front end and an upward protrusion 13b of the open lever 13. The protruding piece 17 is always
a is stopped at the operating position shown in FIG. 3 where it abuts against a stopper 13c bent upward at the front edge of the left side of the open lever 13.

Therefore, when the release lever 17 is in the operating position, the free end 17b of the release lever 17, which is slightly curved to the right, can come into contact with the left side surface of the unlatch lever 9 of the locking plate 4 when the door is closed. In this state, when the open lever 13 is rotated in the release direction and the free end 17b is brought into contact with the unlatch lever 9 of the locking plate 4, the release lever 17 is opened due to the engagement between the protrusion 17a and the stopper 113. In conjunction with the lever 13, the locking plate 4 can be rotated to the release position as shown in FIG.

When the tailgate is closed with the open lever 13 in the release position, the release lever 1
7, the release lever 17 is rotated clockwise in FIG. 3 against the biasing force of the spring 18, and is disengaged from the open lever 13. As shown in FIG.
7b is located at a non-operating position away from the rotation locus of the unlatch lever 9.

The present invention is provided with a release lever configured as described above, so that in normal operation, the remote control bundle rotates the open lever in the release direction, links the release lever to the open lever, and prevents the release lever from moving to the side of the road. By holding the lever and rotating the unlatch lever to the release position,
The door can be opened from a remote location by disengaging the latch and the striker, and even if the door is closed with the open lever still in the release position due to an erroneous operation or malfunction when the door is opened. Also, when the unlatch lever comes into contact with the release lever, the release lever disengages from the open lever and rotates to the inoperative position, which reduces the impact when the unlatch lever collides with the release lever and prevents breakage of both members. etc. can be prevented, and the conventional drawbacks can be eliminated.

Further, the present invention can be easily implemented by simply adding a release lever to the conventional configuration, and has great practical benefits.
