[0032] The present application is further described in detail below with reference to the accompanying drawings and embodiments.

[0033] The present application embodiment discloses a battery lock that can be forced to unlock. Figures 1 to 4 , including a battery lock body 1, the battery lock body 1 includes a top cover 2, an assembly upper shell 3 and an assembly lower shell 4, the assembly lower shell 4 is provided with a mounting groove 5, and the top cover 2 covers the assembly lower shell 4 to form a mounting cavity 6.

[0034] The assembly lower shell 4 is provided with a locking hole 7, which passes through the assembly lower shell 4 to the installation cavity 6. The cavity wall of the installation cavity 6 is provided with a sliding convex strip 8, and the length direction of the sliding convex strip 8 is in the direction toward the locking hole 7. The installation cavity 6 is provided with a lock tongue 9, and the lock tongue 9 is provided with a sliding groove. The sliding convex strip 8 is embedded in the sliding groove. The lock tongue 9 slides on the sliding convex strip 8 through the sliding groove. The sliding direction of the lock tongue 9 is the length direction of the sliding convex strip 8. The lock tongue 9 is provided with an inclined surface 10, which is located at one end of the lock tongue 9 protruding from the outer wall of the battery lock body 1, and the inclined surface 10 is used to abut the door frame.

[0035] The installation cavity 6 is provided with a driving member 11 and a gear set 12. The driving member 11 is connected with a worm 13. The driving member 11 drives the worm 13 to rotate. The worm 13 is meshed with the gear set 12. The gear set 12 is meshed with a lock tongue pull rod 14. The assembly upper shell 3 is located in the installation cavity 6. The assembly upper shell 3 is provided with a positioning strip 15. The length direction of the positioning strip 15 is parallel to the length direction of the sliding convex strip 8. The lock tongue pull rod 14 slides on the positioning strip 15. The sliding direction of the lock tongue pull rod 14 is the length direction of the positioning strip 15. The lock tongue pull rod 14 is located on the side of the lock tongue 9 close to the locking hole 7. The lock tongue pull rod 14 is used to resist and drive the lock tongue 9 to move. In the present application, the driving member 11 is a motor.

[0036] A positioning rod 16 is provided on the wall of the installation cavity 6. The length direction of the positioning rod 16 is parallel to the length direction of the positioning strip 15. The positioning rod 16 passes through the lock tongue pull rod 14 and the lock tongue 9. The positioning rod 16 is used to limit the sliding of the lock tongue pull rod 14 and the lock tongue 9.

[0037] The lock tongue 9 is connected to a return spring 17, and one end of the return spring 17 away from the lock tongue 9 is connected to the wall of the installation cavity 6. The elastic force of the return spring 17 makes the lock tongue 9 pass through the locking hole 7 and protrude from the outer wall of the battery lock body 1. The positioning rod 16 is sleeved with a positioning spring 18, one end of the positioning spring 18 is connected to the wall of the installation cavity 6, and the other end is connected to the lock tongue pull rod 14. The elastic force of the positioning spring 18 limits the lock tongue pull rod 14 from driving the lock tongue 9 to move. In actual use, the return spring 17 and the positioning spring 18 are both made of stainless steel.

[0038] The lock tongue 9 is provided with a magnet 19, which is located on one side of the lock tongue 9 close to the gear set 12. The mounting cavity 6 is provided with a locking Hall sensor 21 and an unlocking Hall sensor 20, which are both used for platform connection. When the lock tongue 9 passes through the locking hole 7 and protrudes from the outer wall of the battery lock body 1, the magnet 19 triggers the locking Hall sensor 21, and when the lock tongue 9 is located in the locking hole 7, the magnet 19 triggers the unlocking Hall sensor 20.

[0039] The implementation principle of a battery lock that can be forced to unlock according to an embodiment of the present application is as follows: in actual use, when an unlocking operation is required, the driving member 11 drives the worm 13 to rotate, and the rotation of the worm 13 drives the lock tongue pull rod 14 to move. The movement of the lock tongue pull rod 14 causes the positioning spring 18 to be in a stretched state. At this time, the lock tongue pull rod 14 causes the lock tongue 9 to move to be located in the locking hole 7. At this time, the magnet 19 triggers the unlocking Hall sensor 20, and the battery lock body 1 is in an unlocked state.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
