[0005] The elastic connecting piece comprises a lifting block which is slidingly installed in the inner cavity of the hollow slide plate, and a lock spring is arranged between the bottom surface of the lifting block and the bottom of the inner cavity of the hollow slide plate.
[0006] The utility model also comprises a groove arranged on the bottom surface of the lifting block and a plug column arranged on the bottom of the inner cavity of the hollow slide plate, the groove is coaxial with the plug column, and the two ends of the lock spring are respectively inserted into the groove and outside the plug column.
[0007] The transmission structure comprises a worm installed on the output shaft of the motor, a transmission screw in threaded transmission connection with the lifting block is rotatably installed in the shell, and the transmission screw is in transmission connection with the worm through a helical gear.
[0008] The transmission structure further comprises a lifting block spring which is sleeved outside the transmission screw and is arranged between the bottom surface of the outer end of the lifting block and the bottom surface of the inner cavity of the shell.
[0009] The shell comprises a bottom shell with a lock bolt sleeve at the bottom, the lock bolt is slidingly inserted into the lock bolt sleeve, a cover plate is fixedly installed on the top of the bottom shell through screws, rotation holes are arranged on the bottom of the inner cavity of the bottom shell and the inner side wall of the cover plate, and the transmission screw is rotatably installed in a pair of rotation holes.
[0010] The top of the cover plate is provided with a filling groove which surrounds the top edge of the cover plate.
[0011] The bottom of the hollow slide plate is provided with a T-shaped groove with an open bottom end, a T-shaped clamping block is fixedly arranged at the top end of the lock bolt, and the T-shaped clamping block is rotatably installed in the T-shaped groove.

[0014] The beneficial effects of this utility model are as follows:
[0015] When locking, the motor operates, and the lifting block compresses the latch spring, thereby driving the hollow sliding plate and the latch to achieve locking. The advantage of this structure is that the latch cannot extend if it is not aligned with the latch hole on the frame. During motor operation, the lifting block absorbs the stroke by compressing the latch spring, allowing the motor to reach the locked state. After the electric locking process is completed, the vehicle head is rotated until the latch hole in the workshop aligns with the lock latch. The latch then extends due to the spring force of the latch spring, locking the vehicle.
[0016] The optional large motor configuration, combined with worm and helical gear transmission, provides a large transmission torque. The reliability of the worm and gear engagement is such that the worm cannot be driven to rotate by rotating the helical gear. Therefore, when the motor is not working, the helical gear, worm, and worm sleeve are always locked (which can solve the problem of the latch extending during vehicle vibration).

[0030] Furthermore, the elastic connector 42 includes a lifting block 421 with one end slidably installed in the inner cavity of the hollow slide plate 41, and a latch spring 422 is provided between the bottom surface of the lifting block 421 and the bottom of the inner cavity of the hollow slide plate 41.
[0031] Furthermore, it also includes a groove 423 on the bottom surface of the lifting block 421 and a post 424 on the bottom of the inner cavity of the hollow slide plate 41.

[0047] ① When the hollow slide plate 41 descends and the latch state sensing magnet 56 moves to the sensing position of the latch locking detection Hall 53, the Hall sensing feedback signal (low frequency) is generated. At this time, the latch unlocking detection Hall 52 senses the feedback signal (high frequency), and it is determined that the current latch 2 is extended (locked state).
[0048] ② When the hollow slide plate 41 rises and the latch state sensing magnet 56 moves to the sensing position of the latch unlock detection Hall 52, the Hall sensing feedback signal (low frequency) is generated. At this time, the latch locking detection Hall 53 senses the feedback signal (high frequency), and it is determined that the current latch 2 is retracted (unlocked state).
[0049] ③ When the transmission screw 432 rotates and drives the lifting block 421 to descend, the motor unlocking state detection Hall 54 moves to the position of the motor 3 locking detection Hall sensing position. At this time, the motor 3 locks the Hall sensing feedback signal (low frequency) and the motor 3 unlocks the Hall sensing feedback signal (high frequency). It is determined that the motor 3 is currently running to the latch 2 lockable state.
[0050] ④ When the transmission screw 432 rotates and drives the lifting block 421 to rise, the motor unlocking state detection Hall 54 moves to the position of the motor 3 unlocking detection Hall sensing position. At this time, the motor 3 unlocking Hall sensing feedback signal (low frequency) is generated. At this time, the motor 3 locking detection Hall sensing feedback signal (high frequency) is generated. It is determined that the motor 3 is currently running to the unlockable state of the latch 2.
