Problems solved by technology

Traditional car companies often restructure the body frame structure of fuel vehicles to arrange battery packs, but such restructured body structures cannot effectively and fully utilize the space, and it is difficult to maximize the battery pack layout space, so its cruising range is often short
[0004] Existing electric vehicles have heavy frames or small battery packs, poor battery life, and fewer power transmission paths in the lower frame, poor anti-collision capabilities of electric vehicles, and it is difficult to guarantee the safety of drivers and passengers

Abstract

The object of the present invention is to provide an electric vehicle lower frame and an electric vehicle having better collision resistance, better safety, and capable of mounting a larger battery pack for longer range. The lower frame includes a left side rail assembly, a right side rail assembly, a frame cross beam assembly, a center channel assembly, a left door sill beam assembly and a rightdoor sill beam assembly. The frame cross beam assembly includes at least a first cross beam, the second cross beam and the third cross beam. The first, second and third cross beams are connected to and fixed between the left and right side rail assemblies. The second cross beam is connected and fixed between the middle of the left longitudinal beam assembly, and that middle of the right longitudinal beam assembly. The first cross beam is locate on the front side of the second cross beam, the third cross beam is located on the rear side of the second cross beam, the left door sill beam assemblyis fix on the left side of the left longitudinal beam assembly, the right door sill beam assembly is fixed on the right side of the right longitudinal beam assembly, and the middle passage assembly is longitudinally arranged.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile lower frame and an electric automobile. Background technique [0002] With the rapid development of electric vehicles, more and more companies have begun to join the manufacturing army of electric vehicles, but the cruising range of electric vehicles is a key bottleneck restricting its rapid development. In order to obtain a higher mileage, the battery pack needs to occupy a large layout space, and its mass generally accounts for more than 20% of the vehicle's mass. [0003] Emerging car companies often sacrifice collision safety to obtain larger battery pack layout space. Traditional car companies often restructure the body frame structure of fuel vehicles to arrange battery packs, but such restructured body structures cannot effectively and fully utilize the space, and it is difficult to maximize the battery pack layout space, so its cruising range is often short . ...
