Electric vehicle chassis

Abstract

The invention provides an electric vehicle chassis comprising a chassis body, a battery module and a bottom plate. The chassis body comprises a pair of parallel longitudinal beams opposite to each other and a plurality of suspended supporting plates located between the longitudinal beams. the battery module comprises a battery assembly and a containing structure for containing the battery assembly, the containing structure comprises an upper cover plate and a lower cover plate, the upper cover plate is fixed to the suspended supporting plates, the bottom plate is arranged at the bottom ends of the longitudinal beams, and the lower cover plate abuts against the bottom plate. According to the electric vehicle chassis, the battery assembly is contained in the containing structure in a modular mode, the upper cover plate of the containing structure is fixed to the suspended supporting plates, the gravity of the battery assembly is borne by the suspended supporting plates and the pair of longitudinal beams, the stress of the bottom plate is reduced, and safety performance is high. Besides, the battery assembly is disposed in the inner structure of the chassis, integration of the battery assembly and the chassis is achieved, and the requirement for light weight is met.

AI Technical Summary

Problems solved by technology

The battery is the core of an electric vehicle, and it is also a comprehensive embodiment of automotive engineering and power engineering technology. The existing electric vehicle chassis is mainly to remove the traditional power system such as the engine from the traditional vehicle chassis, and mount the battery box with the battery. Modular grouping is difficult to realize, and the arrangement of battery modules is chaotic, which poses safety hazards, and the bottom plate carrying the battery modules is under a large force, the strength of the bottom plate is difficult to guarantee, and it is easy to deform
