[0002] With the wide application of new energy batteries, the demand for the capacity of new energy batteries is also increasing day by day. The research on how to combine multiple small-box batteries to form a large-capacity battery is also increasing day by day. When multiple small-box batteries form a large-capacity battery, it is necessary to set a box cover structure outside the multiple small-box batteries to protect the internal small-box batteries. Therefore, the design of the battery box cover is particularly important.

[0003] In the prior art, small-box batteries are usually placed on a bottom plate in series or in parallel, and then five box cover plates are welded outside the small-box batteries to form a box cover, so that the small-box batteries are fixed between the box cover and the bottom plate.

[0004] The box cover structure in the prior art is formed by welding five box cover plates, which requires multiple weldings and corresponding welding fixture toolings to fix the box cover structure, increasing the production cost. During use, due to too many weld seams, the problem of poor sealing is likely to occur. Summary of the Utility Model

As Figures 1 to 4 shown, a battery box cover sealing structure includes: a box cover 1, a box body 2 and a connecting component 5. The box cover 1 includes a top plate 11 and two first side plates 12. The top plate 11 is a rectangular structure. The two first side plates 12 are arranged at both ends of the top plate 11 along the length direction. The top plate 11 and the first side plates 12 are arranged at an angle. The box body 2 includes a bottom plate 21 and two second side plates 22. The two second side plates 22 are arranged in parallel and at intervals on the bottom plate 21. The two first side plates 12 are respectively located on both sides of the second side plates 22 along the length direction and are attached to the second side plates 22. The top plate 11 covers the top of the second side plates 22 to form a box-shaped structure. The box cover 1 and the box body 2 are connected by the connecting component 5.

[0025] Exemplarily, in the embodiment of the present utility model, the box cover 1 is formed by bending sheet metal, thus forming a top plate 11 and two first side plates 12. The box body 2 can be integrally cast to form the shape of a bottom plate 21 and two second side plates 22. In this way, a battery box structure can be formed without welding the box cover 1 and the box body 2. The two first side plates 12 are arranged at both ends of the top plate 11 along the length direction, and the two second side plates 22 are arranged on both sides of the bottom plate 21 along the length direction.

At this time, the two ends of the first side plate 12 and the second side plate 22 are attached along the length direction, and the top of the top plate 11 and the second side plate 22 are attached, thus forming a battery box structure. Then, fix the box cover 1 and the box body 2 through a connecting component 5. The connecting component 5 can be a buckle structure or a screw and screw hole structure, and fix the connection between the box cover 1 and the box body 2 to form a stable battery box structure.

[0026] A battery box cover sealing structure provided by an embodiment of the present utility model designs the box cover 1 in the form of a top plate 11 and a first side plate 12, and the box body 2 in the form of a bottom plate 21 and a second side plate 22. After covering the box cover 1 on the box body 2, the box cover 1 and the box body 2 are snap-fitted, and the box cover 1 and the box body 2 are fixed through a connecting component 5, so that the box cover 1 and the box body 2 are tightly snap-fitted together to form a battery box cover sealing structure. The battery box cover sealing structure formed by this structure does not need to use a welding process to connect multiple plates. The box cover 1 and the box body 2 formed by one-piece molding are snap-fitted with each other and reinforced by a connecting component, which can achieve the sealing effect and can effectively solve the problem of poor sealing due to weld seams in the prior art.
