Therefore, it should not be construed as a limitation to the present invention. In addition, the terms such as "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0033] This embodiment relates to an anti-theft battery box, which is used to be fixed on an electric vehicle frame (or an automobile frame) to realize power supply to the electric vehicle. Refer to Figures 1-4 , the battery bracket includes a box body 10, a battery pack 20 and a circuit board 30. The box body 10 is generally triangularly arranged. The box body 10 has an accommodation cavity inside, and the box body 10 has a first end 111 and a second end 121; the battery pack 20 is fixedly arranged in the accommodation cavity for external power supply; the circuit board 30 is arranged in the accommodation cavity and is electrically connected to the battery pack 20 for monitoring and managing the charging and discharging process of the battery pack 20 so that the battery pack 20 can operate stably. In addition, the circuit board 30 is also electrically connected to a connecting wire 31. One end of the connecting wire 31 away from the circuit board 30 extends out of the box body 10, and a connection interface is arranged at the end of the connecting wire 31 extending out of the box body 10. It is connected to the electric vehicle through the connection interface, thereby realizing power supply to the electric vehicle.

[0034] The box body 10 is provided with a lock hole 101. The lock hole 101 is located on one side of the box body 10 and penetrates through the first end 111 and the second end 121 of the box body 10. A lock assembly 40 is arranged on the box body 10. The lock assembly 40 is used to cooperate with the lock hole 101 so as to fix the box body 10 on the electric vehicle frame. The lock assembly 40 includes a chain 41 inserted into the lock hole 101 and a lock 42 arranged on the chain 41. In this embodiment, the lock 42 is a password lock. In other embodiments, the lock 42 can also be other types of locks. When in use, by passing the chain 41 through the lock 42 and the electric vehicle frame and fixing the chain 41 through the lock 42, the fixation of the box body 10 is realized, that is, the box body 10 is fixed on the electric vehicle frame, and further the box body 10 has an anti-theft function and is not easily stolen by others.

[0035] In addition, a discharge interface 102 is also opened on the box body 10. The discharge interface 102 is electrically connected to the circuit board 30 and is used for external discharge. Through the arrangement of the discharge interface 102, when a user rides an electric vehicle, the user can charge a mobile communication device such as a mobile phone through the discharge interface 102, that is, the box body 10 also has a power bank function, so that the user will not be troubled by insufficient mobile phone battery power during riding, which has strong practicability and improves the market competitiveness.

[0036] Furthermore, the box body 10 includes a front box body 11 and a rear box body 12. The front box body 11 and the rear box body 12 cooperate to form a receiving cavity, and the front box body 11 and the rear box body 12 are fixed by threaded fasteners.

[0037] In this embodiment, the threaded fasteners are screws. The front box body 11 and the rear box body 12 are fixed by the threaded fasteners to form a complete box body 10, thus ensuring the overall stability of the box body 10 and being easy to disassemble and assemble, which is convenient for maintenance and inspection.

[0038] Furthermore, the battery pack 20 includes a plurality of battery cores 21. The front box body 11 and the rear box body 12 cooperate to form a plurality of receiving cavities 111 for accommodating the battery cores 21. The plurality of receiving cavities 111 correspond to the plurality of battery cores 21 one by one, and the plurality of battery cores 21 are electrically connected to the circuit board 30 through electric connection pieces 22.

[0039] In this embodiment, the plurality of battery cores 21 are connected in series, so that the plurality of battery cores 21 form a complete battery pack 20, thus stably supplying power externally.

[0040] Furthermore, a charging interface 103 is arranged on the box body 10. The charging interface 103 is electrically connected to the circuit board 30, and a sealing cover 104 for closing the charging interface 103 is rotatably arranged on the box body 10.

[0041] It is understandable that through the setting of the charging interface 103, the battery pack 20 can be charged when the remaining power of the battery pack 20 is insufficient, thereby improving the endurance and service life of the battery pack 20. And when the charging interface 103 is not in use, the charging interface 103 is sealed by the sealing cover 104 to prevent external dust, rain, etc. from entering the charging interface 103, realizing the protection of the charging interface 103.

[0042] Further, a fuse hole is provided on the box body 10, and a fuse 105 is arranged in the fuse hole. The fuse 105 is electrically connected to the circuit board 30, and the fuse 105 is used to protect the battery pack 20 and the circuit board 30.

[0043] It is understandable that when the circuit current between the circuit board 30 and the battery pack 20 exceeds the set threshold, the fuse 105 will automatically blow, thereby disconnecting the circuit connection between the circuit board 30 and the battery pack 20. At this time, the battery pack 20 stops supplying power externally or stops charging the battery pack 20, realizing the protection of the battery pack 20 and the circuit board 30, and avoiding the situation that the circuit board 30 or the battery pack 20 is damaged due to abnormal current.

[0044] Further, a switch button 106 is arranged on the box body 10. The switch button 106 is electrically connected to the circuit board 30, and the switch button 106 is used to close or disconnect the output circuit of the circuit board 30 to the outside, so that the battery pack 20 continuously or stops outputting electric energy to the outside.

[0045] It is understandable that through the switch button 106, the output circuit of the circuit board 30 to the outside can be closed or disconnected. That is, when in use, the output circuit of the circuit board 30 to the outside is closed through the switch button 106, so that the battery pack 20 can supply power externally. When not in use, the output circuit of the circuit board 30 to the outside is disconnected through the switch button 106, so that the battery pack 20 stops supplying power, thereby avoiding the situation of power loss caused by the continuous connection of the output circuit of the circuit board 30 to the outside, and thus improving the endurance of the battery pack 20.

[0046] Further, a power indicator light 107 is arranged on the box body 10. The power indicator light 107 is electrically connected to the circuit board 30, and the power indicator light 107 is used to indicate the remaining power of the battery pack 20.

[0047] Through the setting of the power indicator light 107, the user can know the remaining power of the battery pack 20, so that the user can choose to continue riding or charge the battery pack 20.

[0048] Further, the box body 10 is made of high-strength flame-retardant ABS material. By using the high-strength flame-retardant ABS material to make the box body 10, the box body 10 has certain flame-retardant and fireproof properties, thereby improving the safety of the box body 10.

[0049] Furthermore, an NTC probe for detecting temperature is arranged in the accommodation cavity. The NTC probe is electrically connected to the circuit board 30, and the NTC probe is closely attached to the surface of the battery pack 20.

[0050] It can be understood that through the setting of the NTC probe, when the NTC probe detects that the temperature in the accommodation cavity is too high, the circuit board 30 automatically cuts off the circuit output by the circuit board 30 to stop the battery pack 20 from supplying power externally, realizing automatic cooling, thereby avoiding the situation that the temperature in the accommodation cavity continuously rises due to the continuous operation of the battery pack 20, and ensuring the normal operation of the battery pack 20.

[0051] Furthermore, mounting holes 108 are uniformly arranged on the peripheral side of the box body 10 to fix the box body 10 through the mounting holes 108.

[0052] In the specific implementation process, by arranging a plurality of connection blocks or other connecting pieces on the frame of the electric vehicle that are inserted and matched with the mounting holes 108, through the cooperation of the connection blocks and the mounting holes 108, the rapid positioning and fixing of the box body 10 are realized, so that the box body 10 can be stably located on the frame of the electric vehicle, thereby improving the stability of the box body 10.

[0053] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
