[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a solid-state lithium battery packaging structure, comprising a housing 1, a damper 2 disposed inside the housing 1, a storage shell 3 fixedly connected to the outer wall of the damper 2, a rotating plate 4 rotatably connected inside the storage shell 3, a bracket 5 fixedly connected to the outer wall of the rotating plate 4, a connecting frame 6 rotatably connected to the outer wall of the rotating plate 4, the outer wall of the connecting frame 6 slidably connected to the inside of the storage shell 3, a clamping block 7 fixedly connected inside the connecting frame 6, the outer wall of the clamping block 7 slidably connected to the inner wall of the storage shell 3, a battery body 9 slidably connected to the outer wall of the clamping block 7, a limiting block 8 fixedly connected inside the storage shell 3, the outer wall of the limiting block 8 slidably connected to the outer wall of the battery body 9, the outer wall of the battery body 9 slidably connected to the inner wall of the storage shell 3, and a reset component disposed inside the connecting frame 6.

[0026] Specifically, the housing 1 supports the damper 2, and the damper 2 fixes the storage shell 3. The damper 2 absorbs and buffers impacts, reducing damage to the battery body 9. The storage shell 3 fixes the limiting block 8, which assists in limiting the offset of the battery body 9. Heat dissipation holes are provided on both outer walls of the storage shell 3 for heat dissipation. The storage shell 3 supports the rotating plate 4, and the rotating plate 4 fixes the bracket 5. The rotating plate 4 can rotate via the rotating bracket 5. Both ends of the rotating plate 4 support two connecting frames 6. 4. When rotated, the connecting frame 6 will move inside the housing 1. The housing 1 supports and limits the offset of the connecting frame 6, so that the connecting frame 6 can only move inside the housing 1. The connecting frame 6 has a fixing effect on the clamping block 7. The clamping block 7 can be moved to release the clamping of the battery body 9. The clamping block 7 and the limiting block 8 are L-shaped. The battery body 9 slides on the outer wall of the bend of the clamping block 7 and the limiting block 8. At the same time, the outer wall of the clamping block 7 and the limiting block 8 are covered with rubber, so as not to damage the battery body 9. The clamping block 7 can clamp and fix the battery body 9, so as to achieve the function of quick disassembly and installation without the aid of tools.

[0027] Reference Figure 3 The reset assembly includes a limiting post 10, the outer wall of the limiting post 10 is slidably connected to the inside of the connecting frame 6, and a spring 11 is sleeved on the outer wall of the limiting post 10, with both ends of the spring 11 fixedly connected to the outer wall of the connecting frame 6.

[0028] Specifically, there are two connecting frames 6. One end of the limiting post 10 is fixed inside the right connecting frame 6, and the other end of the limiting post 10 slides inside the left connecting frame 6. The limiting post 10 connects the two connecting frames 6 and prevents the connecting frames 6 from shifting. The connecting frames 6 support the spring 11. When the connecting frame 6 moves outward, it will cause the spring 11 to be stretched. The contraction force of the stretched spring 11 can make the connecting frame 6 return to its original position, thereby making the clamp 7 clamp and fix the battery body 9.

[0029] Reference Figure 1 and Figure 2 The outer wall of the shell 1 is slidably connected to the cover 12, the outer wall of the cover 12 is fixedly connected to the connecting post 13, and the upper and lower outer walls of the cover 12 are fixedly connected to the fixing post 14.

[0030] Specifically, the cover 12 has a fixing function for the connecting post 13 and the fixing post 14. The outer wall of the housing 1 has a groove, which allows the connecting post 13 and the fixing post 14 to slide inside the housing 1. The outer wall of the cover 12 is provided with a sealing strip. Through the tight fit between the housing 1 and the cover 12 and the sealing effect of the sealing strip, the sealing effect can be enhanced, and the battery body 9 inside the housing 1 can be prevented from being affected by the outside.

[0031] Reference Figure 2 , Figure 4 and Figure 5 The outer wall of the connecting column 13 is slidably connected to the inside of the housing 1. A rotating block 15 is slidably connected to the outer wall of the connecting column 13. The outer wall of the rotating block 15 is slidably connected to the inside of the housing 1. A rotating column 16 is fixedly connected to the inside of the rotating block 15. The outer wall of the rotating column 16 is rotatably connected to the inside of the housing 1. A support plate 17 is fixedly connected to the outer wall of the rotating block 15. The outer wall of the support plate 17 is slidably connected to the inside of the housing 1. One end of a second spring 18 is fixedly connected to the outer wall of the support plate 17. The other end of the second spring 18 is fixedly connected to the inside of the housing 1. A snap fastener 19 is fixedly connected to the outer wall of the rotating block 15. The snap fastener 19 is located on the outside of the housing 1.

[0032] Specifically, the housing 1 supports the rotating column 16, and the rotating column 16 fixes the rotating block 15. The rotating column 16 rotates inside the housing 1, which allows the rotating block 15 to rotate. The outer wall of the rotating block 15 is inclined, and the outer wall of the connecting column 13 is arc-shaped. The movement of the connecting column 13 causes it to slide on the inclined surface of the rotating block 15 and press against the rotating block 15, causing it to rotate. The housing 1 and the rotating column 16 provide a limit offset for the rotating block 15, preventing it from shifting when rotating left and right. The rotating block 15 fixes the support plate 17, and the second spring 18 resets the support plate 17. The elastic force of the second spring 18 allows the rotating block 15 to return to its original position. The connecting column 13 moves to the inside of the rotating block 15, and the reset action of the second spring 18 allows the rotating block 15 to perform a limit offset on the connecting column 13, thus fixing the connecting column 13 inside the housing 1.

[0033] Reference Figure 2 and Figure 5 The outer wall of the fixing column 14 is slidably connected to the inside of the housing 1. The outer wall of the fixing column 14 is slidably connected to the clamping ring 20. The outer wall of the clamping ring 20 is slidably connected to the inside of the housing 1. A spring 21 is sleeved on the outer wall of the clamping ring 20. One end of the spring 21 is fixedly connected to the outer wall of the clamping ring 20, and the other end of the spring 21 is fixedly connected to the inside of the housing 1.

[0034] Specifically, the housing 1 provides a limiting offset function for the fixed post 14, allowing the fixed post 14 to move back and forth only inside the housing 1. The housing 1 also provides support and limiting offset function for the clamping ring 20, allowing the clamping ring 20 to move only inside the housing 1. The housing 1 and the clamping ring 20 provide support for the spring 3 21, and the elastic force of the spring 3 21 will exert a rebound squeezing effect on the clamping ring 20. When the fixed post 14 moves inside the housing 1, it will squeeze the clamping ring 20 and slide to the middle of the two clamping rings 20. Through the action of the spring 3 21, the clamping ring 20 will clamp the fixed post 14, ensuring the stability of the fixed post 14 inside the housing 1, thereby achieving the effect of the auxiliary cover 12 being tightly fitted with the housing 1.

[0035] Working principle: When it is necessary to encapsulate a solid-state lithium battery, first press the bracket 5 to rotate the bracket 5, and the bracket 5 will cause the rotating plate 4 to rotate. When the rotating plate 4 rotates, it will drive the connecting frame 6 to move inside the housing 3. When the connecting frame 6 moves, it will stretch the spring 11. When the connecting frame 6 moves, it will drive the clamping block 7 to move. Then, the battery body 9 is slid into the housing 3 through the inner wall of the limiting block 8. At this time, slowly release the bracket 5. The spring 11 will pull the connecting frame 6 inward through the contraction force, and then the connecting frame 6 will cause the clamping block 7 to clamp and fix the battery body 9, so as to achieve the effect of quickly installing the battery body 9.

[0036] After the battery body 9 is installed, the cover 12 is attached to the housing 1 and a certain pressure is applied. At this time, the cover 12 will cause the connecting post 13 and the fixing post 14 to slide into the inside of the housing 1. When the connecting post 13 slides, it will squeeze the rotating block 15 and cause the rotating block 15 to rotate through the rotating post 16. When the rotating block 15 rotates, it will squeeze the second spring 18. When the connecting post 13 slides to the inside of the rotating block 15, the second spring 18 will cause the rotating block 15 to rotate back to its original position through its elastic force, thereby clamping the connecting post 13 and preventing it from shifting. At the same time, when the fixing post 14 slides into the housing 1... When the battery body 9 is inside the housing 1, the clamping ring 20 is squeezed, causing it to slide inside the housing 1. The rebound force of the spring 21 causes the clamping ring 20 to clamp the fixing post 14, ensuring the stability of the fixing post 14. This further ensures that the cover 12 is tightly fitted to the housing 1. This device can not only clamp and fix the battery body 9, achieving quick installation and saving time, and keeping the battery body 9 stable to reduce collisions, but also allows the cover 12 to be quickly fitted to the housing 1, ensuring sealing. It can also achieve quick disassembly, facilitating maintenance and inspection.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
