For ordinary technicians in this field, the specific meanings of the above terms in this utility model patent can be understood according to specific circumstances.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] according to Figures 1 to 4 A lock body assembly includes a base 1, a motor 2, a driving component 3, and a cover plate 5. The motor 2 is fixed in the middle of the base 1, and the output end of the motor 2 is connected to the driving component 3. The cover plate 5 is fixed on the top of the base 1. The improvement is that a driving groove 7 is provided on the upper part of the base 1, and the driving component 3 is provided in the driving groove 7. The motor 2 is connected and drives the lock tongue 12 through the driving component 3, and an emergency unlocking mechanism 8 is fixed on the top of the cover plate 5.

[0021] The driving assembly 3 includes a driving block 9 and an unlocking block 10 that cooperate with each other. A rack 13 is provided in the middle of the driving block 9, and the rack 13 meshes with a gear 16 at the output end of the motor 2. When the gear 16 at the output end of the motor 2 rotates clockwise and counterclockwise, the driving block 9 can move forward and backward. A driving pin 18 is fixed to the bottom of the unlocking block 10, and the front part of the corresponding driving block 9 has a supporting part 19 that pulls the driving pin 18 to move. The driving block 9 drives the unlocking block 10 to move backward through the driving pin 18, and the tail end of the unlocking block 10 is provided with a spring hole 20, and a spring 14 is fixed in the spring hole 20, which conflicts with the spring positioning sheet 6 on the base 1, and keeps the unlocking block 10 pushing forward all the time. The lock tongue 12 is arranged at the front end of the unlocking block 10 to match the lock hole, so as to achieve insertable fixation.

[0022] The emergency unlocking mechanism 8 includes an L-shaped lock bar 15, which is rotatably fixed to the cover plate 5 through an axle pin 21, and a torsion spring 17 is fixed to the axle pin 21. One end of the torsion spring 17 is fixedly connected to the L-shaped lock bar 15 to maintain a rotation force of the L-shaped lock bar 15. One foot of the L-shaped lock bar 15 cooperates with a push column 23 on the unlocking block 10 passing through the cover plate 5. When the L-shaped lock bar 15 rotates, it drives the push column 23 to move horizontally. The other foot of the L-shaped lock bar 15 is connected to the cable, and a limit column 11 is provided on the cover plate 5 to limit the other foot of the L-shaped lock bar 15. The cover plate 5 is provided with an unlocking guide hole 24 at the position of the spring 14 and the unlocking block 10 for one foot of the L-shaped lock bar 15 to extend out. A safety column 4 is provided at the tail end of the driving block 9. Correspondingly, a micro switch 22 for controlling whether the motor 2 works is arranged on the front and rear sides of the safety column 4 on the base 1. When the safety column 4 touches the micro switch on any side, the motor 2 will be turned off to prevent the driving block 9 from being damaged.

[0023] When the user uses this product to unlock, he only needs to operate the motor 2 to work, the gear at the output end of the motor 2 rotates, and drives the driving block 9 to move horizontally. When the driving block 9 moves, it drives the unlocking block 10 to move to complete the unlocking function. When the motor 2 stops working, the spring 14 at the tail end of the unlocking block 10 will push the unlocking block 10 to reset, and the driving pin 18 at the bottom of the unlocking block 10 will also drive the driving block 9 to reset. When the lock hole contacts the lock tongue 12 at the front end of the unlocking block 10 again, the lock hole and the lock tongue 12 cooperate to complete the locking work.

[0024] When the motor 2 stops working, the user can quickly unlock the car through the emergency unlocking mechanism 8 on the cover plate 5. The user only needs to pull the rope tied to one leg of the L-shaped lock bar 15 by hand, and the other leg of the L-shaped lock bar 15 cooperates with the push column 23 on the unlocking block 10 to achieve unlocking. When the user releases his hand, the torsion spring 17 will apply force to reset the L-shaped lock bar 15 until the L-shaped lock bar 15 hits the limit column 11 and stops.
