Electric automobile frame

Abstract

The invention discloses an electric automobile frame which consists of three constructional units, namely a front part, a middle part and a rear part. The electric automobile frame comprises a beam, girders and a floor, wherein the beam is laterally arranged on the floor, and the girders intersecting with the beam are longitudinally arranged on the floor. The girders comprise left girders and right girders, wherein the left girders include a front floor left girder and a middle floor left girder, and the right girders include a front floor right girder and a middle floor right girder. The middle floor left girder is positioned between the left edge of the middle floor and the front floor left girder, and the middle floor right girder is arranged between the right edge of the middle floor and the front floor right girder. At least one support is arranged between the floor and the girders, and girder reinforcing blocks are further arranged on two sides of the automobile body. The invention which is novel and smart in design is appropriately provided with a plurality of components to greatly reinforce the rigidity and strength of the entire car, thereby protecting the safety of the inside power battery and passengers in the cabinet in case of critical operating conditions like collision.

Description

【Technical field】 [0001] The invention relates to a design scheme of an electric vehicle structure, in particular to a design scheme of an electric vehicle frame structure. 【Background technique】 [0002] With the increase of oil consumption, the gradual reduction of proven reserves and the rapid rise of refined oil prices, the signs of energy crisis are slowly appearing. At present, major automobile manufacturers in the world are competing to conduct research on new energy technologies for automobiles. Among many new energy alternative technologies, electric vehicles are undoubtedly developing very rapidly and have practical significance, and their development prospects are broad. The usual practice is to make structural and technical improvements on the basis of existing relatively mature fuel vehicles. In the design of electric vehicles, the power battery is used to provide driving energy. However, due to the need to install a very large power battery pack, under the cha...

AI Technical Summary

Problems solved by technology

In the design of electric vehicles, the power battery is used to provide driving energy. However, due to the need to install a very large power battery pack, under the chassis structure of the existing fuel vehicle, it is necessary to replace the front beam, rear beam, and left longitudinal beam. And the battery pack is installed in the right longitudinal beam, because the area formed by it is quite narrow, it is impossible to install enough power batteries, which limits the range of electric vehicles

Furthermore, due to the increase of the power battery pack, the weight of the vehicle body will increase significantly, and the strength of the existing fuel vehicle body cannot meet the requirements of electric vehicles, so further technical improvements are needed to meet the requirements of electric vehicles. car needs
