Problems solved by technology

Moreover, traditional power battery packs mostly use sheet metal bending, which is made by manual cutting and manual bending. The product consistency is low, and the production capacity and efficiency are also reduced, making it difficult to achieve mass production supply; in addition, the traditional Power battery packs are mostly welded with secondary protection, and the welding deformation is large, which is extremely easy to affect the molding quality and the sealing effect of the electric box

Abstract

The invention relates to a metal plate stamping electric box which is arranged on the bottom part of an electromobile. The metal plate stamping electric box comprises an upper cover, a plurality of module fixing beams for installing battery modules, and a bottom shell, wherein the upper cover and the bottom shell are integrally formed by adopting metal plate stamping; the upper cover is detachablyconnected onto the bottom shell; an installation space for holding the battery modules is formed between the upper cover and the bottom shell; the module fixing beams are located in the installationspace and are welded and fixed with the bottom shell. According to the metal plate stamping electric box provided by the invention, all components of the electric box are assembled by adopting a metalplate stamping process matched with a welding manner, and through the all components formed by metal plate stamping, the consistency and the strength of the quality of a box body can be effectively controlled, and the overall structure strength of the electric box is favorably improved; in addition, compared with an existing metal plate bending manner, the upper cover and the bottom shell are integrally stamped formed without the need to be welded, so that the air tightness is good, and rainwater can be effectively prevented from entering.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a sheet metal stamping electric box.
