utilize in the lock body electronic signal's trigger and feedback discernment lock body state promptly, the auto-lock function of electric actuator 5 in the cooperation lock body to can prevent that pawl 32 from not reseing when cardboard 31 breaks away from cardboard second lock position and the cardboard 31 that leads to is locked once more problem, the purpose is once only opened for guaranteeing that the cardboard is smooth promptly, and concrete implementation is:

during the operation described in the above description of the electric start function, when the electric actuator 5 is out of the neutral position and triggers the gear switch 63, and the latch 32 is opened to the latch open position and triggers the latch switch 61, due to the self-locking relationship generated by the mutual engagement between the worm 52 of the electric actuator 5 and the helical gear portion 531 of the first transmission gear 53, that is, the worm 52 can drive the first transmission gear 53, but the first transmission gear 53 cannot drive the worm 52 in the opposite direction, at this time, no matter the motor 51 is continuously energized or stops energizing, the latch 32 will be continuously pressed against the open input protrusion 322 of the latch 541 by the open output protrusion of the second transmission gear 54 and cannot be reset to the latch lock position; until the clamping board 31 crosses the second clamping board locking position to trigger the clamping board switch 62, the above signals judge that the clamping board is completely separated from the range of being locked again at the moment, namely, the lock body is completely opened;

the actuator can then be reset by reversing the motor 51 until the gear switch 63 is no longer triggered to stop energisation, at which time the actuator moves from the open position to the neutral position; the opening output protrusion 541 of the second transmission gear 54 thereof is also unlocked from the opening input protrusion 322 of the latch claw 32, and the latch claw 32 has the possibility of continuing to return to the latch claw lock position.

3. Electric suction locking function

The function of utilizing the motor reversal to make the lock body locking promptly, concrete implementation mode does:

when the motor 51 is reversely electrified and then reversely rotated, the worm 52 drives the first-stage first transmission gear 53 to rotate, the first transmission gear 53 drives the second-stage second transmission gear 54 to rotate, after the electric actuator is separated from the middle position, the triggering contour 542 of the second transmission gear 54 triggers the gear switch 63, the second transmission gear 54 drives the third-stage third transmission gear 55 to rotate, the third transmission gear 55 pulls the pulling output protrusion 551 to push the pulling input protrusion 421 of the pulling arm 42 to rotate and transmit the acting force to the connecting rod 41, the protrusion 411 of the connecting rod 41 is matched in the arc groove 313 and pushes against the edge of the arc groove 313 at the moment, and the clamping plate 31 can cross the second clamping plate locking position from the clamping plate opening position; at this time, the card signal protrusion 314 no longer contacts the signal receiving protrusion 641 of the card signal identification lever 64, and the card signal identification lever 64 is reset under the action of the reset spring 65, so that the signal output protrusion 642 no longer triggers the card switch 62; then the catch plate 31 continues to be pushed to the catch plate full-locking position, at this time the latch dog 32 is reset to the latch dog locking position, and the latch dog switch 61 is not triggered any more; when the lock body is locked, the actuator mechanism moves from the middle position to the suction position;

when the locking claw switch 61 is not triggered any more, the motor 51 rotates forwards again to reset the actuating mechanism until the gear switch 63 is not triggered any more and the power is stopped, and at the moment, the actuating mechanism moves to a middle position from a suction position; the third transmission gear 54 pulls the output protrusion 551 out of contact with the pull-in input protrusion 421 of the pull-in arm 42; the suction arm 42 can also be matched with a suction mechanism return spring 43, when the suction mechanism enables the clamping plate 31 to move to the clamping plate full-locking position, the suction mechanism return spring 43 can store energy, the suction arm 42 can be rotated to reset to the initial position state under the action of the spring force of the suction arm, meanwhile, the suction arm 42 drives the connecting rod 41, the protruding part 411 of the connecting rod 41 slides along the clamping plate circular arc groove 313, and finally, the connecting rod 41 is also rotated to reset to the initial position state; and finishing the suction action completely.

4. Emergency reset function of internal mechanism

When the lock body takes place to cut off the power supply or when whole car does not have electricity etc. unusually like if opening the actuation in-process promptly, because its mechanism has moved intermediate state, and the mechanism has self-locking function, probably can't directly open or the lock body of locking, need be to the emergent back that resets of lock body internal portion mechanism, just can normally open or the locking, concrete implementation is:

when the electric actuator 5 moves from the neutral position to the opening position or the suction position, the gear return spring 82 can store energy; the first-stage first transmission gear 53 is clamped by the gear shifting fork 81 and can be disengaged from the meshing position and the worm 52 under the action force of the gear shifting fork 81 to move to the disengagement position, and meanwhile, the shifting fork reset spring 83 is enabled to store energy; at this time, after the first transmission gear 53 is disengaged from the worm 52, the first transmission gear 53, the second transmission gear 54 and the third transmission gear 55 are all reset to the neutral position under the action of the gear reset spring 82; if the suction process is emergent reset, the suction mechanism 4 of the suction mechanism enables the suction arm 42 and the connecting rod 41 to be reset to the initial position state under the action of the suction reset spring 43;

after the attraction mechanism 4 and the electric actuator 5 are reset, the external force to the gear shifting fork 81 is removed, and the first transmission gear 53 can be reset to the meshing position from the disengagement position by the gear shifting fork 81 under the action force of the shifting fork reset spring 83; the emergency reset action of the internal mechanism of the lock body is completed;

5. emergency opening function

After the internal mechanism of the lock body is reset in an emergency, the door lock can be manually opened through the emergency opening arm 71, and the specific implementation mode is as follows:

the emergency opening arm 71 is pivotally fixed to the housing 11, and an external force moves the emergency protrusion 324 of the latch 32 by rotating the emergency opening arm 71, so that the opening protrusion 711 thereof moves from the latch locking position to the latch opening position, thereby performing a mechanical emergency opening function.

The above working engineering of the present invention is an example for clearly illustrating the present invention, and is not a limitation to the embodiments of the present invention. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
