The working principle of the electric suction lock is as follows:

1. and (3) locking process:

firstly, referring to fig. 5-1, by the action of external force, the first shift lever 33 is operated to shift the stopper 31 to rotate (and at the same time, the latch tongue 41 can be driven to rotate), so that the first abutting portion 311 on the stopper 31 contacts with the third abutting portion 412 on the latch tongue 41, at this time, the rotation of the stopper 31 just enables the first trigger block 34 on the stopper 31 not to abut against the contact of the first microswitch 25 any more, so as to trigger a half-lock signal, the lock rod 10 is driven by the latch tongue 41 to enter into the second locking notch 413 of the latch tongue 41 through the first locking notch 111 on the main lock frame 11, and is in a half-lock state, referring to fig. 5-2, because the first abutting portion 311 abuts against the third abutting portion 412 on the latch tongue 41, the latch tongue 41 cannot rotate towards the opening direction, and is kept in the current state, referring to fig. 5-2; after receiving the half-lock signal, the driving mechanism 5 is started, and the rack 71 moves linearly from the original position toward the second shift lever 43 of the latch bolt assembly 4 until the third shift lever 72 on the rack 71 contacts the second shift lever 43 of the latch bolt assembly 4; after that, the rack 71 continues to move, and the lock tongue 41 is turned towards the full-locking direction (at the same time, the block 31 can be driven to turn), until the first abutting part 311 on the block 31 contacts the second abutting part 411 on the lock tongue 41 and abuts against each other, at this time, the second trigger block 44 on the lock tongue 41 just turns to a contact point capable of abutting against the second microswitch 26, so as to trigger a full-locking signal, at this time, the lock rod 10 is locked in the second locking notch 413 of the lock tongue 41, and the block 31 and the lock tongue 41 cannot turn towards the opening direction due to the abutting of the two abutting parts to keep the current state; finally, the driving mechanism 5 is controlled to run reversely by the full-locking signal, the rack 71 moves away from the second shift lever 43 of the latch bolt assembly 4 until the original position is stopped (the triggering concave portion 73 triggers the third microswitch 74, so that the driving mechanism 5 is controlled to stop), and the locking action is finished, as shown in fig. 5-3.

2. Unlocking process:

first, referring to fig. 5-3, a signal (unlock signal) is input to the driving mechanism 5 through the vehicle interior control module, and the driving mechanism 5 is started, so that the rack 71 moves linearly from the original position to the first shift lever 33 of the stop block assembly 3 until the third shift lever 72 on the rack 71 contacts the first shift lever 33 of the stop block assembly 3; thereafter, the rack 71 continues to move, the toggle stopper 31 rotates in the lock opening direction (and simultaneously can drive the lock tongue 41 to rotate), so that the first abutting portion 311 on the stopper 31 contacts the third abutting portion 412 on the lock tongue 41, at this time, the rotation of the stopper 31 just enables the first trigger block 34 on the stopper 31 to abut against the contact of the first micro switch 25, the second trigger block 44 on the lock tongue 41 no longer abuts against the contact of the second micro switch 26, the full-lock signal is released, the lock rod 10 is completely separated from the second locking notch 413 of the lock tongue 41, the driving mechanism 5 runs in the reverse direction, the rack 71 is driven to return to the original position and then stops, the stopper 31 and the lock tongue 41 respectively keep the current state through the first torsion spring 35 and the second torsion spring 45, and the unlocking action is finished, see fig. 5-1.

3. Emergency manual unlocking:

in the fully locked state, the first shift lever 33 of the stopper assembly 3 is manually moved in the unlocking direction, and the rotation of the stopper 31 and the lock tongue 41 causes the lock rod 10 and the second locking port 413 of the lock tongue 41 to disengage, so that the door body can be pushed open. When the third shifting lever 72 does not return to the original position and suddenly loses power, the door body can be pushed away through the actions, because the transmission mechanism 6 adopts a non-self-locking worm and gear structure, the door can be unlocked through manual operation.

The actuating mechanism 7 which drives the stop block assembly 3 and the bolt assembly 4 to move is arranged to be in linear motion with the rack 71, so that the driving force of the third deflector rod 72 on the rack 71 is increased, the force for driving the first deflector rod 33 and the second deflector rod 43 can be improved to the maximum extent, and the stability and the reliability of the electric suction lock are improved; the energy loss of the driving mechanism 5 to the automobile storage battery is reduced, and the reliability is obviously improved; the transmission mechanism 6 adopts a multi-head worm, so that the transmission efficiency of the worm and gear mechanism is improved, and the worm and gear mechanism is not designed in a self-locking matching manner and can drive each deflector rod externally; the structure is simple, the parts are conventional, only one direct current motor and one gear box mechanism are actually driven, the universality can be realized, and the purchasing cost is reduced; only three signal sources are used for processing, and the control is relatively simple.
