Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. At the same time, lithium batteries have the advantages of relatively high energy, long service life, high rated voltage, high power tolerance, very low self-discharge rate, light weight, and strong adaptability to high and low temperatures.

[0034] Reference Figure 3-Figure 5A filter plate 4 is fixedly connected to the middle of the protective shell 1, and a shell 5 is fixedly connected to the side of the protective shell 1 away from the filter plate 4. A filter plate 2 6 is fixedly connected to the middle of the shell 5. The filter plate 2 6 can provide an inlet for air to enter, and an outlet for air to be discharged can be provided under the action of the filter plate 4, so that the air can circulate in the protective shell 1 and the shell 5, and the battery component 16 can be dissipated. A sleeve 7 is fixedly connected to the inside of the shell 5, and a fan 8 is arranged in the middle of the sleeve 7. A pulley 9 is fixedly connected to the side of the fan 8 away from the filter plate 2 6, and a pulley 9 is rotatably connected to the middle of the sleeve 7. The outer periphery of the two pulleys 9 is sleeved with a synchronous belt 10. When the fan 8 rotates, the air can pass through the filter plate 2 6 and enter the shell 5. At the same time, when the fan 8 rotates, it can drive one of the pulleys 9 to rotate. At this time, under the action of the synchronous belt 10, the two pulleys 9 can rotate simultaneously.

[0035] Reference Figure 1-Figure 3 , one side of one of the pulleys 9 is fixedly connected with a gear 11, and the middle part of the housing 5 is rotatably connected with a gear ring 12, the gear 11 and the gear ring 12 are meshed with each other, and the side of the gear ring 12 close to the filter plate 2 6 is fixedly connected with a fixed plate 13, and the other side of the fixed plate 13 is installed with a scraper 14, and the scraper 14 is in contact with the side of the filter plate 2 6 away from the fan 8. When the two pulleys 9 rotate, one of the pulleys 9 can drive the gear 11 to rotate, and the gear 11 can drive the gear ring 12 to rotate, so that the gear ring 12 can slowly drive the fixed plate 13 and the scraper 14 to clean the filtering surface of the filter plate 2 6, thereby preventing the filter plate 2 6 from being blocked. At the same time, there is no need for employees to clean the filter plate 2 6 regularly, thereby reducing the labor intensity of employees.

[0036] Reference Figure 4 and Figure 5 The scraper 14 is specifically installed on the side of the fixing plate 13 away from the gear ring 12 by screws. The scraper 14 can be installed or removed by means of screws. The scraper 14 and the filter plate 26 can be replaced when the scraper 14 or the filter plate 26 is damaged. A driving assembly is fixedly connected to the middle of the casing 7, and the driving assembly includes a motor 15.

The motor 15 can be fixed to the middle of the casing 7 by the fixing rod, and the output end of the motor 15 can be connected to the fan 8. A diverter plate 17 is fixedly connected to the inside of the protective shell 1. A plurality of through holes are opened in the middle of the diverter plate 17. The incoming wind can be dispersed and blown to the battery component 16 through the diverter plate 17 and the through holes, so that the heat of the battery component 16 can be more evenly dissipated.

[0037] Reference Figure 6A damping rod 18 is fixedly connected to the inner bottom of the protective shell 1, and the other end of the damping rod 18 is fixedly connected to the bottom of the movable plate 2. Two vertical plates 19 are fixedly connected to the inner bottom of the protective shell 1, and a connecting rod 20 is fixedly connected between the two vertical plates 19. The outer periphery of the connecting rod 20 is slidably connected to two movable blocks 21. The far sides of the two movable blocks 21 are fixedly connected to compression springs 22, and the other ends of the two compression springs 22 are respectively fixedly connected to the close sides of the two vertical plates 19. The top of the movable block 21 is rotatably connected to a connecting plate 23, and the other side of the connecting plate 23 is rotatably connected to the bottom of the movable plate 2.

[0038] Reference Figure 6 When the battery component 16 vibrates during use or the protective shell 1 is moved to cause the battery component 16 to shake, the battery component 16 will squeeze the damping rod 18 and the movable plate 2, thereby compressing the damping rod 18 and causing the movable plate 2 to squeeze the connecting plate 23. When the connecting plate 23 is squeezed, the movable block 21 will be driven to move. At this time, under the action of the synchronous belt 10, the compression spring 22 can be compressed in cooperation with the movable block 21. When the battery component 16 is stable, the movable plate 2 can be lifted upward under the action of the compression spring 22 and the damping rod 18, thereby resetting the battery component 16, thereby protecting the battery component 16 and avoiding damage to the internal electronic devices when the battery component 16 shakes. A rubber pad 26 is fixedly connected to the bottom of the cover plate 3. When the battery component 16 moves upward, the rubber pad 26 can prevent the battery component 16 from contacting the cover plate 3, thereby preventing the battery component 16 from colliding with the cover plate 3 and causing damage to the battery component 16.

[0039] Working principle: When in use, the fan 8 can be driven by the motor 15 to filter the wind through the filter plate 2 6 and then enter the shell 5 and flow into the protective shell 1 to dissipate heat for the battery 16. At the same time, when the fan 8 rotates, it can drive one of the pulleys 9 to rotate. At this time, under the action of the synchronous belt 10, the other pulley 9 can drive the gear 11 to rotate. When the gear 11 rotates, the gear ring 12 can drive the fixed plate 13 and the scraper 14 to move, thereby cleaning the filtering surface of the filter plate 2 6.

[0040] When the battery component 16 vibrates during use or the protective shell 1 is moved to cause the battery component 16 to shake, the battery component 16 will compress the damping rod 18 and at the same time, the movable plate 2 can be squeezed against the connecting plate 23. When the connecting plate 23 is squeezed, the movable block 21 will be driven to compress the compression spring 22, thereby allowing the battery component 16 to move downward. When the battery component 16 is stable, the movable plate 2 can be reset under the action of the compression spring 22 and the damping rod 18, thereby allowing the battery component 16 to be reset, thereby protecting the battery component 16 and preventing damage to the internal electronic devices when the battery component 16 shakes.

[0041] 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.
