The invention discloses an automobile body side wall rear structure which comprises a column B assembly, a column C assembly and a top edge beam connected with the column B assembly and the column C assembly. The top edge beam is made of aluminum profiles and internally provided with a cavity. The automobile body side wall rear structure is made of the hollow aluminum profiles, the overall weight is small, strength is high, the collision safety performance is more excellent, lightweight of an electric automobile is facilitated, and the cruising mileage of the electric automobile can be effectively increased; and the top edge beam arranged in a penetrating manner is made of the aluminum profiles, the structure is simple, rigidity is good, and the rigidity performance of a side wall assembly is improved.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, in particular, the invention relates to a body side wall rear 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. 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] The rear structure of the body side wall on the body frame of the existing electric vehicle is formed by stamping a steel plate, the forming process is complicated, and the cost is high. The cruising range of the car, and the production, assembly and maintenance costs of metal parts are relatively high, which is not conducive to cost reduction and cannot meet the requirements of energy conser...
