[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-8As shown, this utility model provides a solid-state lithium-ion battery module, including a first connecting plate 1 and a battery module body 4. A moving component 2 is disposed inside the first connecting plate 1. The moving component 2 includes a second connecting plate 201. Multiple evenly arranged first circular holes 202 are formed on both sides of the outer surface of the second connecting plate 201. Second circular holes 203 are formed on both sides of the outer surface of the first connecting plate 1. Sliding shafts 205 are slidably connected to the inner walls of two second circular holes 203. Springs 204 are disposed on the outer surfaces of two sliding shafts 205. Fixed shafts 206 are fixedly connected to both sides of the outer surface of the first connecting plate 1. The outer surface of the second connecting plate 201 is connected to the first connecting plate 204. The inner wall of the connecting plate 1 is slidably connected. The outer surfaces of the two sliding shafts 205 are respectively in contact with the inner walls of the two first round holes 202. The outer surfaces of the two sliding shafts 205 are respectively in contact with the outer surfaces of the two fixed shafts 206. One end of the two springs 204 is respectively fixedly connected to the outer surfaces of the two sliding shafts 205. The other end of the two springs 204 is respectively fixedly connected to both sides of the outer surface of the first connecting plate 1. The battery module body 4 is disposed inside the first connecting plate 1. The other outer surface of the first connecting plate 1 is fixedly connected to the first fixed plate 3. The connecting shaft 5 is fixedly connected between the opposite inner walls of the first connecting plate 1. The outer surface of the connecting shaft 5 is movably fitted with the first cover plate 6.

[0027] The overall effect of Embodiment 1 is as follows: When using a solid-state lithium-ion battery module, the operator needs to place the battery module body 4 inside the first connecting plate 1. At this time, the operator needs to move the second cover plate 7. When the second cover plate 7 rotates, it will drive the first cover plate 6 to rotate. The inner wall of the first cover plate 6 will rotate along the outer surface of the connecting shaft 5 until the outer surface of the first cover plate 6 contacts the outer surface of the first fixing plate 3. At this time, the top of the first connecting plate 1 is empty. Then, the operator places the battery module body 4 inside the first connecting plate 1. When the internal space of the first connecting plate 1 is insufficient to accommodate the battery module body 4, the operator needs to move the sliding shaft 205. The outer surface of the sliding shaft 205 will slide along the inside of the first circular hole 202 and the second circular hole 203. At the same time, the sliding shaft 205 will drive the spring 204 to stretch and no longer contact the outer surface of the fixed shaft 206. When the outer surface of the sliding shaft 205 is no longer in contact with the inner wall of the first circular hole 202, the operator moves the second fixed plate 9. The second fixed plate 9 will drive the outer surface of the second connecting plate 201 to slide along the inside of the first connecting plate 1. When it slides to the appropriate position, one of the first circular holes 206 will... Hole 202 is located directly below sliding shaft 205. When the operator no longer holds sliding shaft 205, the tension of spring 204 pulls sliding shaft 205, causing it to move. The outer surface of sliding shaft 205 slides along the interior of the second circular hole 203 and the first circular hole 202 until the inner wall of the first circular hole 202 completely contacts the outer surface of sliding shaft 205. At this point, the outer surface of sliding shaft 205 also contacts the outer surface of fixed shaft 206. Then, the operator rotates the second cover plate 7 again, causing the first cover plate 6 to rotate until the first cover plate 6 and the second cover plate 7 are in a horizontal position. At this point, the operation... When the personnel move the second cover plate 7, the outer surface of the second cover plate 7 will slide along the inner wall of the first cover plate 6 until the second cover plate 7 drives the first magnet 8 and the second magnet 10 to attract each other. At this time, the outer surface of the second cover plate 7 is in contact with the outer surface of the second fixing plate 9. This device, by setting the moving component 2, moves the second connecting plate 201 to protect and structurally support solid-state lithium-ion battery modules of different sizes, thereby solving the problem that different solid-state lithium-ion battery modules require battery packaging boxes of different sizes, resulting in low passability of battery packaging boxes for solid-state lithium-ion battery modules.

[0028] Example 2: As Figures 1-8 As shown, a second cover plate 7 is slidably connected to the inner wall of the first cover plate 6. A first magnet 8 is fixedly embedded on one outer surface of the second cover plate 7. A second fixing plate 9 is fixedly connected to one outer surface of the second connecting plate 201. A second magnet 10 is fixedly embedded on one outer surface of the second fixing plate 9. The first magnet 8 and the second magnet 10 attract each other.

[0029] The effect achieved by the entire embodiment 2 is that when a solid-state lithium-ion battery module is in use, and the operator needs to close the battery module body 4, the operator needs to move the second cover plate 7. The outer surface of the second cover plate 7 will slide inside the first cover plate 6. When the second cover plate 7 moves close to the outer surface of the second fixing plate 9, the first magnet 8 and the second magnet 10 gradually attract each other. Through the attraction of the first magnet 8 and the second magnet 10, the outer surface of the second cover plate 7 can be attached to the outer surface of the second fixing plate 9, thereby ensuring a tight connection between the second cover plate 7 and the second fixing plate 9 and increasing the stability of the structure.

[0030] Working Principle: When using a solid-state lithium-ion battery module, the operator places the battery module body 4 inside the first connecting plate 1. When the space inside the first connecting plate 1 is insufficient to accommodate the battery module body 4, the operator moves the sliding shaft 205 until the outer surface of the sliding shaft 205 no longer contacts the inner wall of the first circular hole 202. At this point, the operator moves the second fixing plate 9. When the second fixing plate 9 slides to the appropriate position, the operator no longer holds the sliding shaft 205. The tension force of the spring 204 pulls the sliding shaft 205, causing its outer surface to slide along the interior of the second circular hole 203 and the first circular hole 202 until the inner wall of the first circular hole 202 completely adheres to the outer surface of the sliding shaft 205. Then, the operator moves the sliding shaft 205 again. The second cover plate 7 drives the first cover plate 6 to rotate until the first cover plate 6 and the second cover plate 7 are in a horizontal position. Then, the second cover plate 7 is moved. When the second cover plate 7 moves close to the outer surface of the second fixed plate 9, the first magnet 8 and the second magnet 10 gradually attract each other. Through the attraction of the first magnet 8 and the second magnet 10, the outer surface of the second cover plate 7 can be made to adhere to the outer surface of the second fixed plate 9, thereby ensuring a tight connection between the second cover plate 7 and the second fixed plate 9 and increasing the stability of the structure. This device, by setting the moving component 2, protects and supports solid-state lithium-ion battery modules of different sizes by moving the second connecting plate 201, thereby improving the passability of the battery packaging box of the solid-state lithium-ion battery module.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
