[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the prior art, multiple small lithium batteries are mostly fixed together using glue. Although this fixing method is simple to operate, the glue has strong adhesion and may corrode the lithium batteries, thereby affecting the service life of the small lithium batteries. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a combined small lithium battery.

[0023] Example 1:

[0024] To ensure the lifespan of small lithium batteries, combined with Figures 1-4 As shown, a modular small lithium battery is proposed. The lithium battery body is set as the main body of the device. Multiple assembly mechanisms 1 are set on the outside of the lithium battery body. The assembly mechanisms 1 are used to assemble and splice multiple lithium battery bodies. A protective mechanism 2 is set on the outside of the assembly mechanism 1 to effectively protect the multiple assembly mechanisms 1.

[0025] To facilitate the easy assembly and connection of multiple small lithium batteries, an assembly mechanism 1 is proposed. A mounting top plate 106 is used to mount a fixing box 101 to the outside of the lithium battery body. The top of the fixing box 101 has a first irregularly shaped slot 102, and a first irregularly shaped block 103 is fixedly connected to one side of the fixing box 101. Multiple mounting slots 104 are also provided on the top of the fixing box 101. Multiple mounting blocks 105 are fixedly connected to the four corners of the top plate 106, and a second irregularly shaped block 107 is fixedly connected to one side of the top plate 106. Two fixing components 108 are provided on the top of the fixing box 101 to fix the multiple fixing boxes 101. Multiple top plates 106 and multiple fixing boxes... Each of the 101 has heat dissipation holes at its bottom to dissipate heat from the lithium battery body. By placing a single lithium battery body into a fixing box 101, and engaging the first irregularly shaped locking block 103 on one fixing box 101 with the first irregularly shaped locking slot 102 on another fixing box 101, multiple fixing boxes 101 can be combined and connected. By engaging the multiple mounting blocks 105 and the second irregularly shaped locking block 107 on the top plate 106 with the multiple mounting slots 104 and the first irregularly shaped locking slot 102 respectively, the top plate 106 can be easily installed with the fixing box 101. This allows multiple lithium battery bodies to be easily connected through the fixing box 101, ensuring the performance of the small lithium battery.

[0026] Example 2:

[0027] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, multiple small lithium batteries are mostly fixed with glue. Since the glue has strong adhesion, it may corrode the lithium battery, thereby affecting the service life of the small lithium battery. However, after multiple fixing boxes 101 are assembled, in order to ensure the stability of the assembly between multiple fixing boxes 101, they should be further protected and fixed.

[0028] To further protect and secure the multiple fixing boxes 101 together, in conjunction with Figure 1 and Figure 2 as well as Figure 4As shown, a protective mechanism 2 is proposed, which consists of a protective frame 201, a main side plate 205, and a secondary side plate 206. Multiple ventilation holes 202 are provided on both sides of the protective frame 201. Two square grooves 203 are provided on one side of the secondary side plate 206 and the protective frame 201. Two square blocks 204 are fixedly connected to the other side of the main side plate 205 and the protective frame 201. A second irregularly shaped slot 207 is provided on the top of the secondary side plate 206. A cover plate 208 is installed on the top of the protective frame 201. Multiple through holes 209 are provided on the cover plate 208. First magnetic plates are installed inside the multiple square grooves 203, and second magnetic plates are installed inside the multiple square blocks 204. The irregularly shaped card block 103 and the multiple second irregularly shaped card blocks 107 are the same in shape and size. The multiple first irregularly shaped card slots 102 and the second irregularly shaped card slots 207 are the same in shape and size. By sequentially placing multiple fixing boxes 101 into the protective frame 201, and by installing the square slot 203 on the sub-side plate 206 with the square block 204 of the protective frame 201, the first magnetic plate in the square slot 203 and the second magnetic plate on the square block 204 are attracted and connected. Through the square slot 203, the first magnetic plate, the square block 204, and the second magnetic plate, the multiple protective frames 201 can also be combined and connected, thereby matching the size of the multiple fixing boxes 101 and ensuring the protection effect of the small lithium battery.

[0029] To fix the cover plate 208, a fixing component 108 is proposed. Two pull rods 1081 are fixedly connected to the top of multiple fixing boxes 101. Fixing blocks 1082 are fixedly connected to the multiple pull rods 1081. Through slots 1083 are opened on both sides of the fixing blocks 1082. A set of springs 1084 is fixedly connected in each of the two through slots 1083. Stop blocks 1085 are fixedly connected to each of the two sets of springs 1084. By pressing the multiple stop blocks 1085, the multiple stop blocks 1085 are moved into the multiple through slots 1083, so that the size of the pull rods 1081 matches the through holes 209 on the cover plate 208. After the cover plate 208 is installed, under the action of the multiple sets of springs 1084, the multiple stop blocks 1085 can limit the position of the cover plate, further ensuring the protective effect of the device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
