Problems solved by technology

[0002] Our country is currently in the period of vehicle energy conversion, and new energy vehicles are increasing day by day. In major enterprises, the demand for battery boxes of new energy vehicles is huge, and the size of battery boxes for each model is different. Therefore, it is necessary to design a A side wall that can be spliced ​​and combined into a whole box to adapt to boxes of various sizes. In addition, most of the traditional box side walls and floor parts adopt an integral design, or the box wall adopts an integral design, which has better The sealing effect is good, but its processing is difficult, which is not conducive to mass production. At the same time, the weight of the traditional box is also heavy, and there are problems in transportation and installation.

Embodiment 1

[0032] Embodiment one: if figure 1 As shown, the side wall of the battery box in this embodiment includes a side wall body 1, the top of the side wall body 1 is provided with an upper flange 11 extending horizontally to the outside, and the bottom of the side wall body 1 is provided with a lower flange extending horizontally to the outside. Flange 12, the bottom of the side wall body 1 is provided with an inner flange 13 extending horizontally inward.

[0033] During the assembly process, the upper flange 11 and the lower flange 12 are respectively connected and fixed with other parts or respectively connected with the lower flange 12 and the upper flange 11 of another side wall body 1 arranged up and down. Specifically, one side The upper flange 11 of the wall and the lower flange 12 of the other side wall are fixed by bolts, and the body 1 of the side wall abuts against each other.

[0034] Preferably, the bottom end of the lower flange 12 is lower than the bottom end of th...

Embodiment 2

[0040] Embodiment two: if figure 2 As shown, the assembled combined battery box of this embodiment includes a bottom plate 4 and a plurality of side walls of the battery box as described in any one of claims 1 to 6, the bottom plate 4 is a polygonal structure arranged horizontally, and a plurality of the above-mentioned batteries The side walls of the box are vertically arranged and distributed at positions corresponding to each side of the bottom plate 4, and are connected end to end in turn to form a columnar frame structure, and the edges of the bottom plate 4 are respectively welded and fixed on the corresponding above-mentioned The bottom end surface of the inner flange 13 is located in the corresponding installation notch 2 , and the side end of the bottom plate 4 abuts against the side end of the lower flange 12 at the corresponding installation notch 2 .

[0041] preferred, such as image 3 As shown, both sides of the side walls of the above-mentioned battery case ar...

Embodiment 3

[0043] Embodiment three: as Figure 4 As shown, an expandable battery box group includes a plurality of assembled assembled battery boxes in the second embodiment above, and a plurality of assembled assembled battery boxes are stacked sequentially from bottom to top, and two adjacent assembled assembled battery boxes The side walls correspond to each other, and the lower flange 12 at the bottom of the side wall of the assembled assembled battery box above and the upper flange 11 at the top of the side wall corresponding to the assembled assembled battery box located below are respectively fixed by bolts, The expansion and application of the battery box group is more convenient, which greatly meets the needs of users, and the expansion is more convenient.

[0044]Preferably, on the upper flange 11 and the lower flange 12 in each of the above-mentioned battery box side walls, there are correspondingly provided with several fixed reserved holes 3 passing through it, one of the ab...

Abstract

The invention relates to a battery box side wall, an assembly type assembled battery box and an expandable battery box set. The battery box side wall comprises a side wall body, an upper flange horizontally extending to the outer side is arranged on the top of the side wall body, a lower flange horizontally extending to the outer side is arranged at the bottom of the side wall body, and an inner flange horizontally extending to the inner side is arranged at the bottom of the side wall body. The assembly type assembled battery box comprises a rectangular base plate and four battery box side walls, wherein the four battery box side walls are all vertically arranged, and connected end to end to form a rectangular frame structure, the base plate is horizontally arranged, and four sides of the base plate are respectively welded and fixed to the bottom surfaces of the corresponding inner flanges. The battery box side wall, the assembly type assembled battery box and the expandable battery box set have the advantages that the side wall is simple and reasonable in design, can be produced in bulk, and is simple to be assembled with the base plate; and the assembled battery box is simple in structure, convenient to use, high in expandability and strong in practicability.
