Abstract

The invention discloses an electric automobile front side member assembly with a threaded casing pipe structure. A front side member (2) made of an aluminum profile is arranged in a front cabin. Front cabin supports (1) are installed on the front side member (2) through front cabin support installation structures (4). By the adoption of the above technical scheme, a DC / DC converter, a storage battery and the like in the front cabin can be installed and fixed more stably and reliably and are unlikely to be loosened; and the connecting structure is reasonable and compact, and installation and fixing are convenient.

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 front side member assembly of an electric vehicle with a threaded sleeve structure. 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 aluminum profile body of the electric vehicle, DC / DC and batteries need to be installed in the front cabin, and DC / DC and batteries are installed through two front cabin brackets. However, the electric vehicle body made of aluminum pr...
