An upper body of an mpv model or a van model

Abstract

The invention discloses an upper vehicle body of an MPV model or a VAN model, which comprises a front-end module, a front wall module, two front side wall modules arranged at left and right intervals, two rear side wall modules arranged at left and right intervals, and a windshield top. Beam module, front roof beam module, support beam module, rear roof beam module, rear wall module. Each module is composed of aluminum alloy extruded profiles in the form of cavities and aluminum alloy stamped plates, so that the upper body is made of all aluminum alloys, and different modules are reasonably configured with different connection methods, so that the upper body has Sufficient strength and rigidity, and each module is formed independently, so that modular production assembly can be realized. In addition, the structural form of the key components of the upper body is also designed and optimized, so that the upper body is a one-piece frame structure with high strength and rigidity.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an upper vehicle body of an MPV model or a VAN model. Background technique [0002] The upper body of a traditional MPV (Multi-Purpose Vehicles, multi-purpose vehicle) model or a VAN (closed van) model is made of steel plates through stamping, welding, electrophoretic coating and other processes. [0003] This type of upper body has the following disadvantages: the body is heavy and cannot meet the increasing technical requirements for energy saving and emission reduction, especially the lightweight requirements of new energy vehicles; the risk of corrosion is high, resulting in a reduced service life; the manufacturing process is complicated , the number of parts is large, resulting in high manufacturing costs. [0004] In view of this, it is a technical problem to be solved by those skilled in the art to develop a new type of upper vehicle body that can avoid the above dis...
