The outer side wall of the other slider 3 is fixedly connected to another bottom plate 4, and the outer side wall of the bottom plate 4 is fixedly connected to a base 5. The base 5 is rotatably connected to a double rod 6 on the side away from the battery body 2. When the bottom plate 4 is subjected to force, the double rod 6 will rotate on the base 5, and the base 5 is rotatably connected to a single rod 7 on the side away from the battery body 2.

[0028] Reference Figure 3-Figure 4 The single rod 7 here is similar to the double rod 6. The outer part of the double rod 6 is slidably connected to the inner wall of the single rod 7.

The groove 10 and the limiting block 13 here provide stable support for the spring 11.

[0030] Reference Figure 2-Figure 4 The outer wall of the top column 12 is rotatably connected with a connecting block 14, and the adjacent sides of the two bottom plates 4 are rotatably connected with a rotating rod assembly, and the rotating rod assembly includes a long rod 15 and a long rod 2 16. One end of the long rod 15 and the long rod 2 16 are respectively rotatably connected to the adjacent sides of the two bottom plates 4. When external force is applied here, the long rod 15 and the long rod 2 16 will rotate to unload the force, and one end of the long rod 15 is rotatably connected to one side of the long rod 2 16. The right inner wall of the battery shell 1 is fixedly connected with a heat dissipation assembly.

[0031] Reference Figure 2 , Figure 4 and Figure 5 The heat dissipation component includes a fan 17. The heat dissipation component here prevents the battery body 2 from overheating and causing overload during operation, and cannot continue to work. The left side of the fan 17 contacts the right side of the battery body 2. The outside of the fan 17 is fixedly connected to the right inner wall of the battery shell 1. The upper and lower ends of the right side of 1 are fixedly connected with fixed blocks 24. The adjacent sides of the two fixed blocks 24 are detachably connected with a filter 18. The filter 18 here is used to filter dust and impurities in the air. The upper and lower sides of the filter 18 are provided with slide grooves 19. The inner wall of the slide groove 19 is slidably connected with a button 20, and the outer sleeve of the button 20 is provided with a spring 21.

[0032] Reference Figure 2 , Figure 4 and Figure 5 The slide groove 19 here provides a stable sliding space for the button 20, one end of the spring 21 is fixedly connected to one side of the inner wall of the slide groove 19, and the other end of the spring 21 is fixedly connected to the outer side of the button 20.

[0033] Working principle: This battery plastic shell is made of polypropylene, which can effectively prevent the occurrence of short circuit. When the outside world is impacted, the force will first act on the battery shell 1, and then be transmitted to the slider 3 and the bottom plate 4. At this time, the bottom plate 4 will be squeezed in the reverse direction and the force will be transmitted to the connecting block 14. At this time, the connecting block 14 will slide in the slot of the bottom plate 4. At the same time, the spring 11 begins to shrink and absorb pressure. The limit block 13 here mainly prevents the top column 12 from escaping from the control of the bottom column 9.

[0034] At this time, the chassis 8 will also start to rotate, driving the double rod 6 and the single rod 7 to rotate on the base 5, absorbing the pressure laterally. At the same time, the long rod 15 and the long rod 2 16 will bend inward to further absorb the force. The fan 17 here is mainly used for heat dissipation of the battery body 2 to prevent it from stopping operation or causing danger due to excessive temperature. The filter 18 here can intercept most of the dust from the outside, but after long-term use, a lot of dust will adhere to its surface, which needs to be cleaned or replaced.

[0035] At this time, the button 20 can be pressed, and the button 20 will transmit the pressing force to the telescopic rod 22 to make it rotate. When the telescopic rod 22 rotates, it drives the block 23 to retract until it is disengaged from the filter 18. At this time, the filter 18 can be removed for cleaning or replacement. When installing, the reverse operation of the above disassembly can be performed. After the block 23 and the filter 18 are completely engaged, release your hand, and the engagement can be completed under the action of the spring 21.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
