Abstract

The invention discloses a vehicle body frame structure, comprising a side assembly; the side assembly comprises an A pillar assembly, a B pillar assembly and a C pillar assembly, the A pillar assembly comprises an A pillar strut and a top edge beam extending from the A pillar strut to the C pillar assembly and connected with the B pillar assembly and the C pillar assembly, and the top edge beam is made of an aluminum profile and has a cavity inside. The vehicle body frame structure made of the hollow profile is low in overall weight and high in strength, has better collision safety, helps lighten an electric vehicle, and can effectively prolong the life of the electric vehicle; the top beam that is arranged through is made with the aluminum profile and is simple in structure and good in rigidity, and rigidity of a whole vehicle body frame is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular, the invention relates to a body frame structure. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection. Electric vehicles are becoming more and more research hotspots in the automotive field.
