Abstract
The invention provides an automobile front longitudinal beam assembly, an automobile chassis structure and an electric automobile. The front longitudinal beam assembly comprises a front longitudinal beam front section, a front longitudinal beam rear section lower portion and a front longitudinal beam rear section upper portion. The front longitudinal beam rear section lower portion and the front longitudinal beam rear section upper portion are spliced through a friction stir welding process to form a front longitudinal beam rear section; the front longitudinal beam rear section and the front longitudinal beam front section are connected through friction stir welding to form a front longitudinal beam assembly. By adopting the scheme, the defects of material performance reduction, thermal stress concentration and the like caused by burn-in can be effectively avoided, the structural performance of the longitudinal beam is more stable, and the strength of the longitudinal beam is effectively improved; toxic smoke and toxic gas cannot be generated, the body health of an operator can be better protected, and environmental pollution is reduced; therefore, the electric automobile is lightin overall weight, high in strength and better in collision safety performance, the light weight of the electric automobile is facilitated, and the endurance mileage of the electric automobile can beeffectively prolonged.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile front longitudinal beam assembly, an automobile chassis structure and an electric automobile. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection; currently, electric vehicles are limited by the mileage of the battery, which puts forward higher requirements for the lightweight of the body. [0003] The body of the electric vehicle with the largest proportion in the current market is restructured from a traditional fuel vehicle; the front longitudinal beam of the vehicle body is formed by steel plate sheet metal and connected by spot welding process. There are many parts and a large investment in molds. It also needs electrophoresis anti-corrosion, which pollutes a lot and is not conducive to environmental protection requirements; another part of the new electric bo...
