The fixed moving member 14 is locked.

Due to the inertia of the weight 12 due to the opposite impact caused by the collision of the vehicle, the swinging member 10 swingably supported by the door 5 swings counterclockwise in FIGS. 2 and 3. By releasing the locked state of the moving member 14 locked to the other end of the spring member 13, the moving member 14 and the link 141 are moved to the left in the drawing by the urging force of the spring member 13. It consists of a movable structure.

When the moving member 14 moves to the left in the figure, the J-shaped movable piece 111 of the limit switch constituting the position sensor 11 comes into contact with the projection 112 to turn on the switch and collide. Is configured to detect

In the collision detection mechanism 1, since the rocking member 10 rocks due to the shock at the time of the collision of the vehicle, the limit switch 11 for releasing the locked state of the door outputs the collision signal (ON signal).

Consisting of a composition.

In the door lock control device of the first embodiment having the above-mentioned structure, in the automatic lock control, as shown in FIGS. 4 and 7, the ignition switch is on, the door is closed, and the door lock is unlocked. If the lock device is not operating, the vehicle speed is, for example, 25 km / h.
If the door is unlocked and the door is unlocked, the auto-lock signal is output.

As shown in FIGS. 5 and 7, the lock control is performed by the door control switch 27 or 28 (see FIG. 1).
(Indicated in the middle) is switched to lock, and when switching from the high level to the low level, if the lock disapproval time T1 at collision is not on, the lock disapproval time at collision T1 is started and the lock relay drive output is at high level. Then, the lock relay is turned on, and when the collision lock disapproval time T1 reaches the set time t, the collision lock disapproval time T1 is stopped and the lock relay drive output is set to the low level.

Further, unlock control is performed by referring to FIGS. 6 and 7.
Door control switch 27 or 28 as shown in
When the lock relay drive time T2 is not on when the switch is switched to the unlock level and the high level is switched to the low level, the lock relay drive time T2 is started, the unlock relay drive output becomes the high level and the unlock signal is released.

1 and 102 are moved by the position sensors 111 to 11
4 electrically detects and the controller 2 outputs a lock release signal based on a collision signal from the position sensors 111 to 114, the operation of the door lock is stopped for a set time t ′. As shown, even if the door control switches 27 and 28 are locked after the release device is activated, the unlocked door lock is prevented from being locked again for the set time t '.

Further, in the door lock control device of the third embodiment, the collision detecting mechanism 1 is made of a spring material, and is rocked at a neutral position in a vertical state where it is engaged with the recess 103 at the lower end by the projecting piece 104. The weight 12 is arranged at the upper end of the rocking member 10, and two switches are arranged on both sides of the rocking member 10, one in each of the front-rear direction and the width direction of the vehicle. As a result, it is possible to eliminate the need for a compensating circuit and measures as in a conventional device using a sensor and to reduce the cost.

(Fourth Embodiment) As shown in FIG. 15, the door lock control device of the fourth embodiment releases the door lock when a lock release signal is output in the third embodiment, and the door lock control device is operated for a predetermined period of time. It is different in that the door lock is prevented from being re-locked for a while, and further, the door lock is unlocked for a set time t and is maintained in an unlocked state. The same parts are designated by the same reference numerals and their description is omitted.

In the door lock control device of the fourth embodiment, as shown in FIG. 14, the position sensors 111 to 114 electrically detect the movement of the swing members 101, 102 due to the impact when the vehicle collides. Then, when the controller 2 outputs an unlock signal based on a collision signal from the position sensors 111 to 114,
Since the unlock control unit 23 unlocks the door lock for a set time t (unlock relay drive output after operation of the release device in FIG. 14) and maintains the unlocked state,
This has the effect of reliably preventing the door lock from being re-locked.

The above-described embodiments are merely examples for the purpose of explanation, and the present invention is not limited to them. Those skilled in the art will recognize from the claims, the detailed description of the invention and the description of the drawings. Modifications and additions can be made without departing from the technical idea of the present invention.
