The external emergency mechanism 21 comprises an emergency pull rod 23, the emergency pull rod 23 is fixedly connected to the lock housing 1, a second compression spring 24 is sleeved on the outer side wall of the emergency pull rod 23, an emergency unlocking shift rod 22 is arranged at one end of the emergency pull rod 23, the emergency unlocking shift rod 22 is of an L-shaped structure, the middle part of the emergency unlocking shift rod 22 is rotatably connected to the lock housing 1, when the detection structure is damaged, the utility model is manually opened, the other end of the emergency pull rod 23 is clamped on the hook 6, the PCB control mainboard 12, the PCB lock hook detection board 14, the speed reduction motor 15, the PCB motor stroke detection board 16 and the outgoing line terminal seat 17 are all fixedly connected to the lock housing 1, the PCB control mainboard 12 is electrically connected with the PCB lock hook detection board 14, the speed reduction motor 15, the PCB motor stroke detection board 16 and the outgoing line terminal seat 17, so as to facilitate the detection work of the utility model, the hook 6, couple 6's inside fixedly connected with reset torsion spring 10, reset torsion spring 10's inside wall fixed connection is on the lateral wall of pivot, and the motion of the couple 6 of being convenient for, the joint has motor inner cup 2 on gear motor 15's the lateral wall, and the joint has detection switch inner cup 3 and back lid 5 on the motor inner cup 2, the installation gear motor 15 of being convenient for.

Specifically, during unlocking, when an unlocking terminal pin of the outgoing line terminal seat 17 receives an unlocking signal, the PCB controls the main board 12 to output current to drive the speed reduction motor 15 to rotate, the motor cam 20 swings the swing rod to move the motor ejection rod 19, so as to push the lock rod 7 to extrude the first compression spring 11, and under the acting force of the reset torsion spring 10 and the push block 18, when the interference surface of the lock rod 7 and the hook 6 is completely separated, the lock rod 7 can be popped out of the hook 6 to completely release the latch hook 8.

The starting position of the rotation of the speed reducing motor 15 is the stop position, and the rotation is positioned by the motor ejector rod 19 and the detection switch on the PCB motor stroke detection plate 16, so that the speed reducing motor can continuously return to the starting fixed position after being unlocked every time, and the running track is rotated for one circle.

When the door is locked, when the door is unlocked, only the lock hook 8 needs to be pushed directly, the problem that a spring placed in the push block 18 and the reset torsion spring 10 of the hook 6 interfere with each other when the spring crosses the lock rod 7 is solved, the first compression spring 11 pushes the lock rod 7 to block the popping track of the hook 6, the lock hook 8 cannot exit in the hook 6, the door locking action is completed at the moment, the push block 18 is internally provided with the spring, the spring is compressed when the door is closed, so that the push block 18 always has outward pushing force to abut against the lock hook 8 when the door is locked, and abnormal sound caused by the fact that the gap can shake after the lock hook 8 is locked due to the gap between the lock hook 8 and the hook 6 hanging groove is avoided.

When latch hook 8 pushed in, couple 6 and locking lever 7 form to interfere when blocking promptly, couple 6 can be impressed and be linked in and detect trigger bar 4 and trigger PCB couple pick-up plate 13 output signal and give PCB control mainboard 12 and reach the state of judging that couple 6 is locked and confirm, and couple 6 releases away when unblanking, and couple detects trigger bar 4 and releases the signal under the effect of the first compression spring 11 of taking certainly, makes PCB couple pick-up plate 13 cut off signal output.

The PCB lock hook detection plate 14 outputs a signal to the PCB control main board 12 when the distance between the magnetic steel 9 assembled in the lock hook 8 is close to a certain position, whether the lock hook 8 is really close to or locked is judged, and the problems of virtual locking, false locking and the like can be better eliminated by double-layer judgment and safety is improved.

The external emergency mechanism 21 is a detachable manual mechanical unlocking mechanism arranged outside the lock body, and the operation principle is that the emergency unlocking driving lever 22 is stirred to drive the emergency pull rod 23 to pull the lock rod 7 to enable the hook 6 to be separated and unlocked, and the emergency unlocking driving lever 22 is loosened to be reset to the initial position together with the emergency pull rod 23 under the driving of the second compression spring 24.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
