Chassis structure of electric automobile

Abstract

The invention provides a chassis structure of an electric automobile. The chassis structure of the electric automobile comprises an upper cover plate, a lower cover plate and a honeycomb-shaped interlayer structure clamped between the upper cover plate and the lower cover plate; the honeycomb-shaped interlayer structure comprises a plurality of same honeycomb units which are adjacently connected;the honeycomb units are hollow and are used for accommodating single-body batteries; the electric automobile chassis comprises a phase change heat-conducting layer; and the phase change heat-conducting layer is arranged between the upper cover plate and the honeycomb-shaped interlayer structure. According to the chassis structure of the electric automobile, the chassis adopts the upper cover plate, the lower cover plate and the honeycomb-shaped accommodating structure made of aluminum alloy materials to replace the existing chassis of solid steel plates and a battery box of the steel plate, aphase change heat-conducting layer prepared by mixing paraffin, polyethylene and graphite is arranged between the upper cover plate and the honeycomb-shaped accommodating structure, and the chassis structure of the electric automobile is high in heat-dissipating efficiency, high in reliability and simple to maintain; meanwhile, the whole weight of the electric automobile is reduced and the whole vehicle energy density of the electric automobile is increased.
