Upper vehicle body of MPV vehicle model or VAN vehicle model

Abstract

The invention discloses an upper vehicle body of an MPV vehicle model or a VAN vehicle model. The upper vehicle body comprises a front end module, a front wall module, two front side wall modules arranged left and right in a spaced mode, two rear side wall modules arranged left and right in a spaced mode, a front windshield upper cross beam module, a front top cross beam module, a supporting crossbeam module, a rear top cross beam module and a rear wall module. Each module is formed by combining an aluminum alloy extrusion profile and an aluminum alloy stamping plate in a cavity form, so thatthe upper vehicle body is made of an all-aluminum alloy material, different connecting modes are reasonably configured among different modules, the upper vehicle body has enough strength and rigidity, all the modules are independently formed, and therefore modular production and assembly can be achieved. In addition, the structural form of key components of the upper vehicle body is optimized, sothat the upper vehicle body is of an integrated 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...
