[0035] The lamp body 5 is provided with a power supply assembly 54 and a quick disassembly and assembly structure, the quick disassembly and assembly structure includes a box opening 55 and a locking structure, the lamp body is provided with a battery cavity 56, the tail end of the lamp body 5 is provided with the box opening 55 connected with the battery cavity 56, the power supply assembly 54 is arranged in the battery cavity 56, and the power supply assembly 54 is connected with the lamp body 5 through the locking mechanism.

[0036] As shown in Figure 1 , 6 , 7, the locking structure preferably includes a hook groove 57 and a lock key 58, the upper end surface of the power supply assembly 54 is provided with the hook groove 57, the lock key 58 is movably mounted on the upper surface of the lamp body 5, and the inner end of the lock key 58 is connected with the hook groove 57; the power supply assembly 54 is loaded into or unloaded from the battery cavity 56 through the box opening 55, after being loaded, the lock key 58 is automatically clamped into the hook groove 57 to realize the connecting in the loading direction, so that the power supply assembly 54 cannot automatically slide out, and thus when the power supply assembly 54 is unloaded, the lock key 58 is pushed to be separated from the position of the hook groove 57, so that the power supply assembly 54 can slide out of the box opening 55.

[0037] The upper end surface of the power supply component 54 is provided with a guide groove and an expanding groove. The guide groove is arranged along the insertion direction of the battery cavity 56. The front end of the guide groove is communicated with the guide groove. The front end of the expanding groove penetrates the front end surface of the power supply component 54. The rear end of the guide groove is communicated with the hook groove 57. When the power supply component 54 is inserted into the battery cavity 56, the lock key 58 can pass through the expanding groove and the guide groove in sequence and is clamped on the hook groove 57. The expanding groove is used to match the initial position of the lock key 58. When the power supply component 54 is just inserted into the hatch 55, the lock key 58 enters the expanding groove first and moves to one side of the insertion direction under the shape limitation. The power supply component 54 continues to be inserted, and the lock key 58 slides along the guide groove. When the power supply component 54 is completely inserted into the battery cavity 56, the lock key 58 slides to the position of the hook groove 57.

Conversely, the lock key 58 is pushed to make it separate from the hook groove 57 and return to the guide groove, so that the power supply component 54 can be disassembled from the battery cavity 56.

[0038] The locking structure further comprises a plate spring. The hook groove 57 and the guide groove are arranged perpendicularly to form an L-shaped through groove structure. One end of the plate spring is fixedly connected with the lamp body 5. The other end of the plate spring is connected with the lock key 58 in cooperation. The plate spring is used to control the position of the lock key 58. The plate spring applies a spring force perpendicular to the insertion direction of the power supply component 54 to the lock key 58. Thus, without external force, the lock key 58 is ensured to be in the hook groove 57 to prevent the power supply component 54 from falling off.

[0039] The front end of the battery cavity 56 is provided with a conductive plate. Two power connection springs are arranged on the conductive plate. After the power supply component 54 is inserted into the battery cavity 56, the two power connection springs are respectively abutted and connected with the power supply component 54 to form a communication circuit. The power connection springs abut the power supply component 54 to realize circuit communication. At the same time, the power connection springs apply an outward pushing force to the power supply component 54.
