[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides the following technical solution: a lithium battery protection structure, including a working box 1 and a lithium battery body 12. The inner wall of the working box 1 is hinged to a first working plate 2. One end of the first working plate 2 is hinged to a second working plate 3. One side of the second working plate 3 is hinged to a transparent box 5. A second connecting block 14 is fixedly installed on one side of the transparent box 5. A connecting rod 15 and a third connecting block 17 are fixedly installed on one side of the surface of the second working plate 3. A first limiting block 13 is rotatably connected to the surface of the connecting rod 15. A working box 19 is provided on the other side of the surface of the second working plate 3. A fourth connecting block 18 is fixedly installed on both sides of the working box 19. A second return spring is fixedly installed inside the fourth connecting block 18. A second limiting block 16 is fixedly installed at one end of the second return spring. Threaded rods 9 are threadedly connected to both sides inside the working box 1. A clamping plate 11 is rotatably connected to one end of the threaded rod 9. A first return spring 10 is fixedly installed on one side of the clamping plate 11. A first connecting block 6 is fixedly installed at the other end of the threaded rod 9.

[0021] In a specific embodiment of this utility model, the lithium battery body 12 is placed inside the work box 1. The operator rotates the first connecting block 6, causing the threaded rod 9 to rotate inside the work box 1, moving the clamping plate 11 inside the work box 1 to clamp the lithium battery body 12 closer together. Conversely, rotating the first connecting block 6 causes the threaded rod 9 to rotate and reset the clamping plate 11. The elastic force generated by the first reset spring 10 improves the ease of reset movement of the clamping plate 11. Then, the first working plate 2 and the second working plate 3 are rotated and placed above and to one side of the lithium battery body 12 to surround and protect the surface of the lithium battery body 12, reducing damage to the lithium battery body 12 from collisions. The operator pinches the upper and lower sides of the fourth connecting block 18. Move the second limiting block 16 to the inside of the fourth connecting block 18, place the fourth connecting block 18 inside the third connecting block 17, release the second limiting block 16, and use the elastic force generated by the second reset spring to move the second limiting block 16 outward and engage it inside the third connecting block 17. Install the working box 19, or disassemble it to connect the lithium battery body 12. The operation is simple and reduces the difficulty of work. The power status and power switch position of the lithium battery body 12 can be observed through the transparent box 5. The operator can rotate the first limiting block 13 to move the first limiting block 13 away from the outside of the second connecting block 14 and rotate the transparent box 5 to open it, or turn it inward to close it. The design is ingenious and improves the convenience of using this structure.

[0022] In this embodiment: the anti-slip block 7 is installed to improve the anti-slip effect of this structure, and the ventilation hole 8 is opened to facilitate heat dissipation at the bottom of the lithium battery body 12 and improve the practicality of this structure.

[0023] The working principle and usage process of this utility model are as follows: After the utility model is installed, the lithium battery body 12 is placed inside the work box 1. The operator rotates the first connecting block 6, causing the threaded rod 9 to rotate inside the work box 1, moving the clamping plate 11 inside the work box 1 to clamp the two sides of the lithium battery body 12 closer together. Conversely, rotating the first connecting block 6 causes the threaded rod 9 to rotate and reset the clamping plate 11. The elastic force generated by the first reset spring 10 improves the ease of reset movement of the clamping plate 11. Then, the first working plate 2 and the second working plate 3 are rotated and placed above and to one side of the lithium battery body 12 to surround and protect the surface of the lithium battery body 12, reducing damage to the lithium battery body 12 from collisions. The operator pinches the upper and lower sides of the fourth connecting block 18, moves the second limiting block 16 into the fourth connecting block 18, places the fourth connecting block 18 inside the third connecting block 17, and then releases it. The second limiting block 16, through the elastic force generated by the second reset spring, moves outward and engages inside the third connecting block 17 for installation of the working box 19; conversely, it can be disassembled for connection of the lithium battery body 12. The power status and power switch position of the lithium battery body 12 can be observed through the transparent box 5. The operator rotates the first limiting block 13 to move it away from the outside of the second connecting block 14, opening the transparent box 5; conversely, it closes it. This eliminates the need for frequent disassembly of the structure using external tools for use of the lithium battery body 12. The anti-slip slider 7 is installed to improve the anti-slip effect of the structure. The ventilation hole 8 is provided to facilitate heat dissipation from the bottom of the lithium battery body 12, improving the practicality of the structure. All electrical equipment in this device is powered by an external power source. The motors, electric push rods, etc., in this device are controlled by a PLC controller system.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
