[0019] The utility model is further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, a lithium battery assembly is provided in the battery compartment, a groove 1-1 is provided on one side of the opening of the battery compartment 1, the notch size of the groove 1-1 is smaller than the bottom size of the groove 1-1, a rotating stopper 8 is provided on the outside of the lithium battery assembly 2, a rotating handle 6 is provided on the outside of the rotating stopper 8, the outer edge of the rotating stopper 8 is located in the groove 1-1, and when the rotating handle 6 is rotated, the outer edge of the rotating stopper 8 is driven away from or close to the notch of the groove 1-1.

[0021] The outer edge of the rotating block 8 is provided with a protrusion 8-1 that matches the structure of the groove 1-1, and the protrusion 8-1 is located in the groove cavity of the groove 1-1. When the protrusion 8-1 is away from the notch of the groove 1-1, since the size of the notch is smaller than the size of the bottom of the groove, the protrusion 8-1 is limited in the groove cavity, and the lithium battery assembly is installed and locked in the battery compartment at this time, ensuring the normal use of the lithium battery assembly. When the lithium battery assembly 2 needs to be disassembled, the rotating handle 6 is turned, and the protrusion 8-1 is close to the notch, which facilitates the disassembly of the lithium battery assembly 2.

[0022] A connecting block 8-2 is provided at one end of the rotating stopper 8, and a connecting groove 6-1 matching with the connecting block 8-2 is provided at one end of the rotating handle 6. Figure 4 As shown, one end of the connection block 8-2 is fixed on the rotating block 8, and the other end of the connection block 8-2 passes through the rotating bracket 7 and abuts against the connecting groove 6-1 of the rotating handle. When in use, the rotating handle 6 is rotated, and under the action of the connection block 8-2, the rotating handle 6 drives the rotating block 8 to rotate, thereby driving the rotating block 8 to approach or move away from the notch of the groove 1-1, thereby facilitating the installation or removal of the lithium battery assembly.

[0023] A rotating bracket 7 is provided between the rotating block 8 and the rotating handle 6, and the rotating bracket 7 is connected to one side of the battery compartment 1 through a fastener 5. The rotating bracket 7 is pressed against the rotating block 8 to fix the rotating bracket 7. When disassembly is required, the fastener 8 is loosened to disassemble the rotating bracket 7.

[0024] The rotating bracket 7 is provided with an avoidance groove 7-1 which matches the structure of the rotating stopper 8. The structure and position of the avoidance groove 7-1 match the rotating stopper protrusion 8-1, and play an avoidance role for the rotation of the protrusion 8-1.

[0025] The number of the grooves 1-1 is one or more, and the number of the protrusions 8-1 matches the number of the grooves 1-1. Figure 1 As shown, in this embodiment, the number of the grooves and the protrusions is two. The shape of the groove 1-1 is L-shaped.

[0026] A waterproof component 4 is provided on one side of the lithium battery assembly 2 to ensure the waterproof performance of the lithium battery assembly. In this embodiment, the waterproof component 4 is a waterproof sealing ring.

[0027] The lithium battery assembly 2 includes a lithium battery pack 2-1 and a lithium battery pack housing 2-2. The lithium battery pack 2-1 is arranged in the battery compartment 1, and the lithium battery pack housing 2-2 is sleeved outside the lithium battery pack 2-1. A mounting groove 2-21 for mounting the waterproof component 4 is provided on one side of the lithium battery pack housing 2-2. Figure 1 , Figure 4 As shown, the waterproof component 4 is sleeved on the outside of the lithium battery pack housing 2-2.

[0028] When the utility model is used, the lithium battery assembly 2 is placed in the battery compartment 1-1, and the waterproof assembly 4 is sleeved on the outside of the lithium battery pack shell 2-2. A rotating block 8, a rotating bracket 7, and a rotating handle 6 are respectively provided on one side of the lithium battery pack shell 2-2. The rotating bracket 7 is fixed to the lithium battery shell 2-2 by a fastener 5, and the rotating block 8 is pressed between the rotating bracket 7 and the lithium battery shell 2-2. The rotating handle 6 is rotated to drive the protrusion 8-1 of the rotating block 8 away from the notch and embedded into the inner side of the groove 1-1, thereby completing the installation and fastening of the lithium battery assembly 2. When disassembly is required, the rotating handle 6 is rotated to drive the protrusion 8-1 close to the notch, so as to facilitate the disassembly of the lithium battery assembly 2.
