The invention relates to the field of vehicle structure, aiming at solving the problems in the prior art that the weight of the vehicle body structure is large and the vehicle body parts are modifiedgreatly and the cost is high in the development process, and providing a variable vehicle body structure, comprising two side skeleton structures, both comprising an upper side beam and a door sill beam, and an A-pillar assembly, a B-pillar assembly and a C-pillar assembly; The front body assembly includes a vertical frame structure and transverse bars thereunder are connected between the front ends of the sill beams on both sides; A plurality of top cover cross beams are distributed along the extension direction of the upper side beams and are respectively connected between the upper side beams on both sides; A rear floor panel is generally constructed to include a horizontal frame structure, and transverse bars on the front side thereof are connected between the rear ends of the sill beams on both sides; The front floor assembly is connected to the transverse bar below the front body assembly, the transverse bar on the front side of the rear floor assembly and the inner side of the outer frame enclosed by the sill members on both sides. The invention has the advantages of being beneficial to the overall lightweight, easy platform expansion and low cost.
Description
technical field [0001] The invention relates to the field of vehicle structures, in particular to variable body structures. Background technique [0002] The body of the existing electric vehicle is generally formed by stamping steel plates, and the stamping parts are welded and assembled according to a certain process sequence to form the body, and the connection methods are mostly spot welding and secondary welding. [0003] The steel plate stamping technology used in the existing car body has a complicated forming process and high cost, and the mass of the resulting car body is large, which is not conducive to the lightweight of electric vehicles, and cannot effectively extend the cruising range of electric vehicles. The cost of metal parts manufacturing, assembly and maintenance is high. It is not conducive to cost reduction, and cannot meet the requirements of energy conservation and environmental protection. And it is not conducive to platform expansion. During the ex...
