Abstract

The invention discloses an electric vehicle subframe structure comprising a front subframe body (1) and a rear subframe body (2). A structural body of the front subframe body (1) and a structural body of the rear subframe body (2) are made of aluminum alloy profiles which are connected through welding or thread connecting pieces. By the adoption of the technical scheme, the subframe structure is manufactured through the hollow aluminum alloy profiles, the overall weight is small, the strength is high, structural safety is better, and the requirements of installation and connection are met. Light weight of an electric vehicle is benefited, and endurance mileage of the electric vehicle can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicle structure, and relates to the structure of an electric vehicle body. More specifically, the present invention relates to a sub-frame structure of an electric vehicle. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection, especially pure electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] On the body of the aluminum alloy profile of the electric vehicle, the sub-frame plays an important role, on which it is required to install mechanical and power components, such as the lower swing arm, steering gear and other mechanical structures, as well as a large number of hig...
