[0023] Embodiment

[0024] Please refer to Figures 1-3, in the illustration: This embodiment is a preferred embodiment in this technical solution. A lithium battery that is easy to assemble includes a lithium battery body 2, a bracket 1 for the combined installation of the lithium battery body 2, and a metal part 3 for the electrical connection of multiple said lithium battery bodies 2; the lithium battery body 2 includes an electric core 21 and an electrode 22 fixed to the end of the electric core 21; the bracket 1 includes a limiting plate 11 snap-fitted to the end of the electric core 21 and a support member 12 disposed between the parallel limiting plates 11; the metal part 3 includes a gasket 32 in contact and fit with the electrode 22 and a connecting piece 31 for the combined connection of multiple said gaskets 32;

[0025] It should be noted that: in the lithium battery that is easy to assemble involved in this application, by setting the bracket 1 to assist in the combined installation of the lithium battery body 2 and setting the metal part 3 for the electrical connection of the combined lithium battery body 2, several said lithium battery bodies 2 are combined to form a lithium battery module, which facilitates the centralized use of the lithium battery body 2. When assembling this combined lithium battery, first fix the lithium battery body 2 to the bracket 1. The circular hole provided in the middle of the limiting plate 11 is used for the limiting installation of the electrode 22, and the jack provided therein is used for the mating installation of the plug-in. Under the action of the plug-in, the limiting plate 11 and the support member 12 are relatively fixed, thereby combining to form the bracket 1 for positioning the lithium battery body 2. Subsequently, the convex and concave positions on the sides of adjacent said limiting plates 11 are mutually matched to complete the combined installation of the bracket 1. Finally, the convexity on the lower side of the gasket 32 is snap-fitted into the circular hole to complete the combined assembly of this lithium battery module.

[0026] Among them, as Figure 1 shown, several said limiting plates 11 are spliced with each other, and the limiting plates 11 cooperating with the electrode 22 at the same end are located in the same plane; the limiting plate 11 is an insulating thin sheet structure, and the limiting plate 11 is a hollow structure; the support member 12 is spaced from the periphery of the electric core 21, and the support member 12 is an insulating hollow structure

[0027] It should be noted that: adjacent said brackets 1 are combined by the splicing of the limiting plates 11, so that the lithium battery bodies 2 fixed inside the brackets 1 are completed in combined assembly. To facilitate the installation of the metal part 3 and the arrangement of the brackets 1, the limiting plates 11 in several said brackets 1 are in the same plane, and the limiting plates 11 and the support members 12 are set as insulating hollow structures, which can reduce the overall weight of the device and avoid conducting electricity with the lithium battery body 2.

[0028] Among them, as Figure 2 shown, the connecting piece 31 and the gasket 32 are both metal thin sheet structures, and the circular convexity on the lower side of the gasket 32 cooperates with the circular hole provided in the middle of the limiting plate 11;

[0029] It should be noted that: the connecting piece 31 and the gasket 32 are both conductive structures for connecting and energizing multiple lithium battery bodies 2. After the circular protrusion on the lower side of the gasket 32 is matched with the circular hole provided in the middle of the limiting plate 11, the planar position of the gasket 32 relative to the limiting plate 11 is fixed. The circular protrusion on the lower side of the gasket 32 contacts the electrode 22, and then through the connection of the connecting piece 31 to several gaskets 32, several lithium battery bodies 2 are combined and energized.

[0030] As shown in Figure 3 the figure, protrusions symmetrically extend from the edge of the limiting plate 11, and depressions are symmetrically provided in the middle of the other two sides of the limiting plate 11; a circular hole is provided in the middle of the limiting plate 11, and the circular hole is matched with the electrode 22; sockets are symmetrically provided near the middle of the limiting plate 11, and plugs are provided in the sockets, and the lower ends of the plugs are inserted into the upper side of the support member 12.

[0031] It should be noted that: the protrusions and depressions at the edges of adjacent limiting plates 11 are matched with each other. The circular hole provided in the middle of the limiting plate 11 is used for the limiting installation of the electrode 22, and the opened sockets are used for the matching installation of the plugs. Under the action of the plugs, the limiting plate 11 and the support member 12 are relatively fixed, thereby combining to form the bracket 1 for positioning the lithium battery body 2.
