[0023] As Figures 1-3 shown, a steel shell of a new energy battery includes a shell 1 and a detachable side plate 2 inserted inside the body of the shell 1.

[0024] The shell 1 is a cuboid with an open top. At the bottom of the inner cavity of the shell 1, there is a combined circular fixing hole 3 for limiting a cylindrical battery. A fixing plane 4 is formed by the inward depression of the side wall of the inner cavity of the shell 1. Limiting grooves 5 are symmetrically arranged on the long sides of the shell 1. An inward depression is provided on the outer side of the top of the shell 1 to form a clamping plane 6, and the outer clamping plane 6 is used for installing a shell top plate (not shown in the figure).

[0025] The detachable side plate 2 is used for limiting a square battery. The detachable side plate 2 is composed of a limiting side plate 201, a connecting plate 202, and an inserting plate 203. The limiting side plates 201 are uniformly arranged on the front surface of the connecting plate 202, and the inserting plates 203 are symmetrically arranged on the back surface of the connecting plate 202. The inserting plates 203 are inserted into the limiting grooves 5 to form a fit. The detachable side plate 2 can be prefabricated in a variety of different types of sizes, that is, the limiting side plates on the front surface of the connecting plate are provided with a variety of spacings, which are applied to the fixation of square batteries with different thicknesses.

[0026] As Figure 1 shown, the limiting groove 5 is a T-shaped groove, and the inserting plate 203 is a T-shaped plate. The heights of the limiting side plate 201 and the connecting plate 202 are slightly lower than the height of the limiting groove 5. The main body of the inserting plate 203 is located inside the inner cavity of the shell and will not be exposed to ensure the subsequent installation of the cover plate. The spacing between the limiting side plates of each detachable side plate can be prefabricated into different spacings to ensure that it can adapt to square batteries with different thicknesses.

[0027] As Figure 3 shown, the outer surfaces of the limiting side plate 201 and the connecting plate 202 are both covered with a rubber layer (not shown in the figure), which can avoid hard contact with the shell of the battery and protect the battery body.

[0028] As Figures 1-2 shown, fixing holes are uniformly arranged on the fixing plane. The fixing holes are used for gland connection. A gland (not shown in the figure) can fix the top of the battery to avoid axial displacement of the battery and improve the stability after installation.

[0029] As Figure 1 shown, multiple groups of heat dissipation holes 101 are provided on the side wall of the housing 1, and the heat generated by the internal battery during operation can be quickly released, avoiding accumulation inside the housing and preventing accidents caused by overheating.

[0030] As Figures 1-2 shown, an annular fixing platform 301 is provided inside the cavity of the combined circular fixing hole 3. The center of the annular fixing platform 301 is recessed downward to form an inner circular fixing hole 302. The annular fixing platform can be used to fix a large-diameter cylindrical battery, and the inner circular fixing hole can fix a small-sized cylindrical battery. One hole serves two purposes, which is convenient and fast.

[0031] The working principle of the present utility model is described as follows: When in use, the cylindrical battery can be inserted into the combined circular fixing hole and then the cover plate can be covered; when fixing the square battery pack, first insert the detachable side plate, and the distance between the limiting side plates of the detachable side plate can be selected according to the thickness of the square battery pack. Fix the square battery between the two limiting side plates and then fix it with the cover plate; thus, multiple groups of single batteries can be assembled into a large-capacity battery box.

[0032] The above-described embodiments are only used to describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model. The technical content claimed by the present utility model has been fully recorded in the claims.
