Full-bearing-type pure electric business purpose vehicle structure

Abstract

The invention discloses a full-bearing-type pure electric business purpose vehicle structure which comprises a full-stamping part front wall, a full-stamping part top cover, a rectangular pipe side wall, a full-stamping part back wall and a truss type chassis assembly. The full-stamping part front wall and full-stamping part back wall skeletons are connected into a whole through the full-stampingpart top cover arranged at the upper portion, rectangular pipe side wall vehicle bodies arranged at the two sides and a truss type chassis assembly arranged at the lower portion to form a whole vehicle box type skeleton vehicle body assembly. The structure has the beneficial effects that compared with a semi-bearing vehicle body, the whole strength of the full-bearing vehicle body is higher; the full-stamping part vehicle body structure is low in mass and good in strength; a chassis front section, a chassis middle section, a chassis back section and a chassis tail section on the truss type chassis assembly are manufactured at the same time, after the sections of the chassis are spliced, the sections and the side walls are welded and fixed to form the whole vehicle body skeleton, and the problems that installation is difficult and the precision is not high due to the buckling procedure are avoided. According to the business purpose vehicle structure, no bin door needs to be formed in the side walls, and the vehicle body structure integrity is not damaged.

Description

technical field [0001] The invention relates to a passenger car structure, in particular to a full load-bearing pure electric commercial passenger car structure, belonging to the technical field of pure electric commercial passenger car structure applications. Background technique [0002] At present, commercial buses basically adopt a semi-load-bearing structure, and there are the following problems: [0003] 1. With a semi-load-bearing structure, due to the problem of mold parts, the space at the bottom is obviously limited, and the layout of chassis components is difficult; and when performing pure electric power conversion, the power battery is often difficult to arrange and install; [0004] 2. With a semi-load-bearing structure, when the body and chassis are connected by buckling, the precise size cannot be measured, and the error is large; [0005] 3. In the semi-load-bearing structure, it is difficult to install the power battery, and it is necessary to open a hatch...
