[0026] Refer to Figures 1-4 As shown, this embodiment provides a housing for a synthetic - metal large - capacity water - lithium battery, including:

[0027] Inner shell 1, the inner shell 1 is a square - tube structure, and a number of vertical reinforcing ribs 5 are arranged at intervals on the outer sides of the two long sides of the inner shell 1, and insert bars 14 are arranged on the outer sides of the two short sides of the inner shell 1;

[0028] Top cover plate, the top cover plate is inserted into the top of the inner shell 1, the top cover plate includes a top plate 2, and insert plates 3 extend vertically downward from both short sides of the top plate 2. A first slot 1815 is arranged on the side of the insert plate 3 close to the inner shell 1, and the first slot 1815 is adapted to the insert bar 14;

[0029] Bottom cover plate, the bottom cover plate is inserted into the bottom of the inner shell 1, the bottom cover plate includes a bottom plate 6, and vertical buckles 17 are arranged vertically upwardly extending from both short sides of the bottom plate 6. A second slot 1918 is arranged on one side of the buckle 17 close to the inner shell 1, and the second slot 1918 is adapted to the insertion bar 14.

[0030] By arranging a plurality of vertical reinforcing ribs 5 on the outer side of the inner shell 1, not only can the structural strength and rigidity of the inner shell 1 be enhanced, but also the heat dissipation range of the outer surface of the inner shell 1 can be increased, thereby enhancing the heat dissipation efficiency of the outer surface of the inner shell 1; by arranging the insertion plate 3 and the buckle 17, the top cover plate can be quickly inserted and buckled with the bottom cover plate and the inner shell 1, thereby facilitating the subsequent welding of the whole shell, and greatly improving the assembly efficiency of the whole shell.

[0031] Further, the height of the inner shell 1 is h1, the height of the insertion plate 3 is h2, and the height of the buckle 17 is h3, where h3 is less than h2, h2 is less than h1, and h3 + h2 = h1.

[0032] By defining the heights of the buckle 17 and the insertion plate 3, it is ensured that the length after the inner shell 1 and the insertion plate 3 are buckled is equal to the height of the inner shell 1, ensuring the overall aesthetic appearance of the shell and also ensuring the airtightness of the whole shell after buckling.

[0033] Further, two groups of insertion blocks 16 are arranged at the bottom of the insertion plate 3, and the two groups of insertion blocks 16 are respectively located on both sides of the first slot 1815.

[0034] Further, two groups of slots 18 are arranged at the top of the buckle 17, and the two groups of slots 18 correspond to the insertion blocks 16.

[0035] By arranging the insertion blocks 16 and the slots 18, the quick positioning and alignment of the top cover plate and the bottom cover plate are realized, facilitating the subsequent welding of the top cover plate and the bottom cover plate, and greatly improving the assembly efficiency of the whole shell.

[0036] Further, a plurality of first transverse reinforcing ribs 4 are arranged at intervals on one side of the insertion plate 3 away from the inner shell 1.

[0037] By arranging the first transverse reinforcing ribs 4, not only can the overall structural strength and rigidity of the top cover plate be enhanced, but also the heat dissipation efficiency of the top cover plate can be enhanced. Secondly, the first transverse reinforcing ribs 4 can also increase the friction force on the surface of the top cover plate, facilitating the workers to move the shell and avoiding the situation of the shell slipping.

[0038] Further, a plurality of second transverse reinforcing ribs 7 are arranged at intervals on one side of the buckle 17 away from the inner shell 1.

[0039] Further, a groove 8 is provided on the outer surface of the top plate 2. Two groups of electrode gaskets are arranged at intervals in the groove 8. The two groups of electrode gaskets are a negative electrode gasket and a positive electrode gasket respectively. A negative electrode interface 10 is provided on the negative electrode gasket, and a positive electrode interface 12 is provided on the positive electrode gasket.

[0040] Further, a resistive electric circle is provided around the periphery of the negative electrode interface 10 and the positive electrode interface 12.

[0041] By providing a resistive electric circle around the periphery of the negative electrode interface 10 and the positive electrode interface 12, the situation that the negative electrode interface 10 and the positive electrode interface 12 are short-circuited with the housing is avoided.

[0042] Secondly, in this embodiment, the resistive electric circle installed on the negative electrode interface 10 is a green resistive electric circle 9, and the resistive electric circle installed on the positive electrode interface 12 is a red resistive electric circle 11. The different colors of the resistive electric circles are used to prompt the user to make a distinction when inserting the wire.

[0043] In another embodiment, a "+" sign is also hot-stamped on the red resistive electric circle 11, and a "-" sign is hot-stamped on the green resistive electric circle 9. The positive electrode interface 12 and the negative electrode interface 10 are further distinguished by the signs.

[0044] Further, an insulating electric circle 13 is also provided between the negative electrode interface 10 and the positive electrode interface 12. The insulating electric circle 13 prevents the conductive phenomenon between the negative electrode interface 10 and the positive electrode interface 12 due to the close distance.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
