Electric vehicle chassis and vehicle body

Abstract

Disclosed are an electric vehicle chassis and a vehicle body. The electric vehicle chassis comprises a base plate module, a pair of side beam modules, and a cell box structural module. The base plate module comprises a plate body, wherein a longitudinal groove opening downward is formed at the bottom of the plate board; and at least a pair of beams is arranged upon plate board at two sides of the longitudinal groove. The side beam module sequentially comprises a front hole seat, a beam body, and a rear hole seat, wherein the side beam module is welded upon the two outside end faces of the base plate module via the beam body. The cell box structural module comprises a substrate and a box cover corresponding to and locked upon the substrate, wherein the substrate and the box cover comprise a first area and a second area; the first area is provided with a first connecting piece corresponding to the position of the beam; the second area is provided with a second connecting piece; the first area of the box cover is embedded into the longitudinal groove of the base plate module; and the first connecting piece of the substrate is locked to the beam. Also disclosed is a vehicle body, comprising a pre-suspending module, a rear-suspending module, and an electric vehicle chassis mentioned above.

Description

technical field [0001] The invention relates to an electric vehicle chassis, in particular to an electric vehicle chassis and a vehicle body including a modularized battery box structural module that can be assembled and disassembled from the bottom of the electric vehicle chassis. Background technique [0002] Generally speaking, the chassis structure of traditional gasoline vehicles does not take into account the storage space for batteries. Nowadays, when car manufacturers develop electric vehicle chassis, they are based on the traditional gasoline vehicle chassis for research and design, and the battery is placed in the trunk. Or under the rear seat, it is quite inconvenient to increase the difficulty of repairing the battery pack or disassembling and replacing the battery module. [0003] In addition, the chassis structure of existing automobiles is not designed in a modular manner, and the convenience of wheelbase adjustment is not considered. When it is applied to dif...

[0002] Generally speaking, the chassis structure of traditional gasoline vehicles does not take into account the storage space for batteries. Nowadays, when car manufacturers develop electric vehicle chassis, they are based on the traditional gasoline vehicle chassis for research and design, and the battery is placed in the trunk. or under the rear seat, making it more difficult to repair the battery pack or disassemble and replace the battery module, which is quite inconvenient

[0003] In addition, the chassis structure of existing automobiles is not designed in a modular manner, and the convenience of wheelbase adjustment is not considered. When it is applied to different models, it is necessary to make a large change in the structure, which increases the development cost of the whole vehicle, which is not conducive to a small number of diverse electric vehicles. car model development
