Battery case for vehicle, assembling method of battery case and vehicle

Abstract

The invention relates to the technical field of vehicle parts, and particularly relates to a battery case for a vehicle, an assembling method of the battery case and the vehicle. The battery case includes a shell, a first transverse inner assembly, a first transverse outer assembly, a second transverse inner assembly and a second transverse outer assembly, wherein the second transverse inner assembly and the second transverse outer assembly are transversely arranged on the inner side and the outer side of the second transverse side wall respectively; each of the first transverse inner assemblyand the second transverse inner assembly includes a supporting piece and a connecting piece; the supporting piece is provided with a step part supporting a battery module, an upper vertical part extending vertically upward from an outer edge of the step part and a lower vertical part extending vertically downward from an inner edge of the step part; and the connecting piece is vertically arranged, the inner side of the connecting piece is connected with the upper vertical part of the supporting piece, the outer side of the connecting piece is connected with the inner side of the correspondingtransverse side wall in the first transverse side wall and the second transverse side wall, and a plurality of through holes corresponding to the connecting piece are formed in the lower vertical part so as to implement connection of the connecting piece to the inner sides of the corresponding transverse side walls through the through the plurality of through holes.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a battery box for a vehicle, an assembly method thereof, and a vehicle. Background technique [0002] An electric vehicle is a vehicle that utilizes the electric power of a vehicle-mounted rechargeable battery as a power source or as one of the power sources. Electric vehicles have the advantages of zero emission, zero pollution and less impact on the environment, and a new energy vehicle is being rapidly developed and developed. [0003] The rechargeable batteries used in electric vehicles are usually mounted on the battery box. The battery case is assembled by welding several components. During welding, the welding needs to be performed sequentially according to the position of each component, because in the prior art, three stations are usually required to assemble the battery box. Since each station consumes a lot of material and human resources, there is a need for ...
