Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A battery case with low cost, light weight and reliable sealing is disclosed, as shown in figure 1, comprising a bottom plate 1; a plurality of folded plates 2 are arranged around the bottom plate 1 in an extending and connecting manner; the folded plate 2 is vertically folded to enclose the periphery of the bottom plate 1; the edges of the adjacent folded plates 2 are connected in a sealing way, and the sealing property can be ensured by adopting the forms of welding and the like; as shown in fig. 2-4, the folded plate 2 comprises an outer vertical plate 21, an inner vertical plate 22 and a skirt 23 which are connected in sequence; the inner vertical plate 22 is bent to form a hollow beam 3; the skirt 23 is located at the end of the flap 2; the skirt 23 is attached to the bottom plate 2;

the cut plate is bent to form the box body, and compared with the existing production mode of aluminum profile extrusion, the dependence on heavy processing equipment can be reduced, so that the production cost is saved, and the manufacturing efficiency is improved; the structural strength of the side face of the box body can be obviously improved through the two-layer structure of the outer vertical plate 21 and the inner vertical plate 22; meanwhile, the hollow beam 3 can be constructed by bending the inner vertical plate 22, so that the overall structural strength of the box body is further greatly improved.

The hollow beam 3 is positioned at least one of the inner side of the outer vertical plate 21 and the upper part of the bottom plate 1; as shown in fig. 5, the hollow beam 3 is provided in plurality; a space is reserved between the adjacent hollow beams 3; through the cooperation of a plurality of hollow beams 3, can form key structure to the bottom plate or the box side and strengthen.

The cross-section of the hollow beam 3 is a rectangular frame, so that the hollow beam has excellent bending resistance, realizes efficient utilization of materials, and is beneficial to light weight of the box body.

The reinforcing blocks are filled in the hollow beam 3 and can be flexibly increased and decreased according to the requirement on the strength of the box body, so that the adaptability of the product to the use environment is obviously improved.

The skirt 23 is connected with the bottom plate 1 through friction stir welding, so that obvious weld joint bulges can be avoided from being generated around a connecting interface, the interior of a product is more regular, and the polishing and cleaning time is saved.

The outer vertical plate 21 is perpendicular to the bottom plate 1, so that a standard cuboid structure can be finally obtained, and regular arrangement of batteries is facilitated.

The bottom plate 1 and the folded plate 2 are aluminum plates, so that the light weight of the product can be fully realized on the premise of meeting the requirements of the bending process.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
