[0029] The technical solution of the present invention will be clearly and completely described below through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1 to Figure 3 As shown, a battery lock includes a lock body bracket 1, a main lock body and an auxiliary lock body, and the main lock body and the auxiliary lock body are both arranged on the same side of the lock body bracket 1. The main lock body, as the main locking structure, has both electronic unlocking and mechanical unlocking functions, and the two unlocking modes are independent of each other. The auxiliary lock body, as an auxiliary locking structure, cooperates with the main lock body. The main lock body and the auxiliary lock body are described in detail below.

[0031] The main lock body includes a main lock housing 2, a main lock core 3, a main lock tongue 4, an electromagnetic moving part and a main lock tongue reset spring 5. The main lock housing 2 is arranged on a side surface of the lock body bracket 1, and the electromagnetic moving part and the main lock tongue reset spring 5 are both arranged in the main lock housing 2. The main lock tongue 4 is movably arranged on the main lock housing 2, and one end thereof penetrates the lock body bracket 1 and protrudes from the other side surface of the lock body bracket 1, and the other end extends into the main lock housing 2 and is connected to one end of the electromagnetic moving part, and the other end of the electromagnetic moving part is connected to the inner wall of the main lock housing 2 through the main lock tongue reset spring 5. The main lock core 3 is arranged in the main lock housing 2, and a hook 6 is connected to its output end and is arranged in cooperation with the electromagnetic moving part.

[0032] The electromagnetic moving part includes an electromagnet housing 7, an electromagnet core 8, a coil (not shown in the figure) and a wire 9, wherein the coil is arranged in the electromagnet housing 7, the wire 9 is arranged outside the electromagnet housing 7 and extends into the electromagnet housing 7 to be connected with the coil, and the electromagnet core 8 is also arranged in the electromagnet housing 7, that is, the two ends of the electromagnet housing 7 are respectively provided with a first moving through hole (not shown in the figure) and a second moving through hole (not shown in the figure), wherein one end of the electromagnet core 8 connected with the main lock tongue reset spring 5 passes through the first moving through hole and extends to the outside of the electromagnet housing 7, and it is connected to the inner side wall of the main lock housing 2 through the main lock tongue reset spring 5, and at the same time, the end is also provided with a hooking groove 10 that cooperates with the hooking member 6. The other end of the electromagnet core 8 is arranged inside the electromagnet housing 7, corresponding to the main lock tongue 4 passing through the second moving through hole and extending into the interior of the electromagnet housing 7 and being integrally formed or fixedly connected with the end, which is the structural mode adopted in this embodiment. Of course, the main lock tongue 4 can also be arranged outside the electromagnet housing 7, and the other end of the electromagnet core 8 can pass through the second movable through hole and extend to the outside of the electromagnet housing 7 to be integrally formed with or fixedly connected to the main lock tongue 4.

[0033] The working principle of the electromagnetic moving part composed of the above-mentioned electromagnet core 8, coil, wire 9 and electromagnet shell 7 is the same as the working principle of the electromagnet in the prior art, that is, the coil is energized by the wire 9 to generate magnetism and then drive the electromagnet core 8 to move back and forth.

[0034] When the battery lock mechanical unlocking function is used, that is, when the key is used for unlocking, the user inserts the key into the main lock core 3 and rotates it, so that the hook 6 at the output end of the main lock core 3 rotates to match the hook groove 10 on the electromagnet core 8. During this rotation process, the electromagnet core 8 moves toward the main lock tongue reset spring 5 and compresses the main lock tongue reset spring 5, and the main lock tongue 4 connected to the electromagnet core 8 also retracts toward the inside of the main lock housing 2 to a position at least flush with the side of the lock body bracket 1, thereby completing the unlocking operation. After the key is pulled out, the electromagnet core 8 moves in the opposite direction under the action of the main lock tongue reset spring 5, and the main lock tongue 4 moves accordingly and protrudes from the other side of the lock body bracket 1 again.

[0035] When using the electronic unlocking function of the battery lock, the user can connect the electric two-wheeled vehicle controller through the APP to energize the coil to generate magnetism, so as to drive the electromagnet core 8 to move toward the main lock tongue reset spring 5 and compress the main lock tongue reset spring 5, and the main lock tongue 4 connected to the electromagnet core 8 also retracts toward the inside of the main lock housing 2 to a position at least flush with the side of the lock body bracket 1, thereby completing the unlocking operation. Afterwards, the coil is powered off, the electromagnet core 8 loses its magnetic effect and moves in the opposite direction under the action of the main lock tongue reset spring 5, and the main lock tongue 4 moves accordingly and protrudes from the other side of the lock body bracket 1 again. Both of the above methods can realize the unlocking of the main lock body, and the unlocking can be completed independently of each other so that users can cope with different unlocking scenarios.

[0036] When the main lock body is unlocked, an auxiliary lock body is also provided between the battery 11 and the battery lock 12 to prevent the battery 11 from falling due to the user's failure to hold the battery 11 firmly in time after the main lock body is unlocked. The auxiliary lock body in the battery lock 12 includes an auxiliary lock shell 13, an auxiliary lock tongue 14, a stopper 15, and an auxiliary lock tongue reset spring 16. The auxiliary lock shell 13 is arranged on the same side of the lock body bracket 1 as the main lock shell 2. The auxiliary lock tongue 14 is movably arranged on the auxiliary lock shell 13 and one end thereof penetrates the lock body bracket 1 and protrudes from the other side of the lock body bracket 1. The other end extends into the auxiliary lock shell 13 and is fixedly connected to the inner wall of the auxiliary lock shell 13 through the auxiliary lock tongue reset spring 16. The stopper 15 is movably arranged in the auxiliary lock housing 13 and is arranged orthogonally to the auxiliary lock tongue 14. A button 17 is arranged on the top of the stopper 15 and the button 17 protrudes from the auxiliary lock housing 13. A sliding transmission structure is arranged between the stopper 15 and the auxiliary lock tongue 14. The sliding transmission structure has the function of transmitting the movement of the stopper 15 to the movement of the auxiliary lock tongue 14 and the movement directions of the two are perpendicular to each other, that is, by pressing the button 17, the stopper 15 moves toward the auxiliary lock tongue 14, and the auxiliary lock tongue 14 is retracted toward the inside of the auxiliary lock housing 13 to a position at least flush with the side of the lock body bracket 1 to complete unlocking. In this process, the auxiliary lock tongue reset spring 16 is compressed. After releasing the button 17, the auxiliary lock tongue 14 moves in the opposite direction under the action of the auxiliary lock tongue reset spring 16, and the stopper 15 moves away from the auxiliary lock tongue 14 through the transmission conversion of the sliding drive structure.

[0037] The above-mentioned sliding transmission structure includes an auxiliary lock tongue moving groove 18 and a stopper moving groove 19, wherein any side surface of the auxiliary lock tongue 14 is provided with an auxiliary lock tongue moving groove 18 along its moving direction, and the stopper 15 is arranged in the auxiliary lock tongue moving groove 18 perpendicular to the auxiliary lock tongue 14 and is movable and arranged in the auxiliary lock tongue moving groove 18. The groove wall of the auxiliary lock tongue moving groove 18 close to the auxiliary lock tongue return spring 16 is an inclined sliding slope surface 20, and the side surface of the stopper 15 close to the sliding slope surface 20 is correspondingly provided with a stopper moving groove 19, and the groove wall of the stopper moving groove 19 close to the sliding slope surface 20 is an inclined abutting slope surface 21, and then, the abutting slope surface 21 has the same inclination as the sliding slope surface 20 and the two are arranged in close contact. When the stopper 15 is pressed and moves toward the auxiliary lock tongue 14, the abutting slope surface 21 on the stopper 15 moves with the stopper 15 and continuously presses down on the sliding slope surface 20. Since the sliding slope surface 20 and the abutting slope surface 21 are arranged obliquely, the auxiliary lock tongue 14 can move in a direction perpendicular to the stopper 15 during the movement of the stopper 15. When the stopper 15 moves toward the auxiliary lock tongue 14, the auxiliary lock tongue 14 retracts toward the inside of the auxiliary lock housing 13 and compresses the auxiliary lock tongue reset spring 16. When the stopper 15 loses the pressing effect, the auxiliary lock tongue 14 moves in the reverse direction to reset under the action of the auxiliary lock tongue reset spring 16, and the stopper 15 also moves in the reverse direction to reset through the transmission of the sliding slope surface 20 and the abutting slope surface 21.

[0038] At the same time, this embodiment is also equipped with a battery box to cooperate with the above-mentioned battery lock 12, see Figures 4 to 6 As shown.

The button opening and the lock core opening on the box body 22 correspond to the positions of the button 17 and the main lock core 3 of the battery lock 12, respectively. Then, the button 17 protrudes from the button opening, and the lock port of the main lock core 3 is located in the lock core opening.

[0039] In order to prevent the battery lock 12 from shifting in the box body 22 due to bumps during riding of the electric two-wheeled vehicle, a plurality of reinforcing ribs 25 are convexly provided on the inner bottom of the box body 22 and bolt holes (not shown in the figure) are provided on the reinforcing ribs 25. A base 26 is provided at the bottom of the lock body bracket 1 and a reinforcing rib fixing groove 27 is correspondingly provided at the bottom of the base 26. The battery lock 12 is embedded in the reinforcing rib fixing groove 27 through the reinforcing rib 25 and is fixed to the inner bottom of the box body 22 through the bolt 24 and the bolt hole on the reinforcing rib 25. The battery 11 is embedded in the box body 22 through the battery opening 23. The side cover of the battery 11 close to the battery lock 12 is fitted with the side of the lock body bracket 1 and a lock groove 28 is provided thereon. The lock tongue of the battery lock 12 is embedded in the lock groove 28 to lock the battery 11.

[0040] When the battery box is arranged on the upper tube of the electric two-wheeled vehicle or arranged on the lower tube with the battery 11 facing upward, a pop-up structure (not shown in the figure) is also arranged on the inner bottom of the box body 22, which is the same as the pop-up structure in the prior art. When the battery 11 is arranged in the box body 22, the battery 11 presses down the pop-up structure and is locked in the box body 22 by the battery lock 12. After the user unlocks the main lock body of the battery lock 12, the pop-up structure can pop up the battery 11 so that one end of it is tilted up for the user to grab, and then the auxiliary lock body is unlocked to remove the battery 11 from the box body 22. When the battery box is arranged on the lower tube with the battery 11 facing downward, the lock groove 28 on the side cover of the battery 11 is a T-shaped groove. When the battery 11 and the battery lock 12 are locked, the main lock tongue 4 of the battery lock 12 is embedded in the horizontal part 29 of the T-shaped groove, and the auxiliary lock tongue 14 is embedded in the vertical part 30 of the T-shaped groove. After the user unlocks the main lock body of the battery lock 12, one end of the battery 11 is exposed from the box body 22 of the battery box under the action of gravity for the user to grab, and the other end moves to make the auxiliary lock tongue 14 slide to the end of the vertical part 30 of the T-slot, and then the auxiliary lock body is unlocked to remove the battery 11 from the box body 22.
