Abstract

The invention discloses an automobile body structure for an electric automobile. The automobile body structure comprises an automobile body framework and multiple automobile body exterior trimming parts covering the automobile body framework and detachably connected with the automobile body framework. The automobile body exterior trimming parts are made of a high polymer material. By the adoption of the automobile body structure for the electric automobile, the automobile body exterior trimming parts are made of the high polymer material, the mass of the automobile body exterior trimming parts is greatly reduced, the automobile body exterior trimming parts are lightweight components, the lightweight requirement of the electric automobile is met, and the beneficial effects that energy is saved, environment friendliness is achieved, and the cruising mileage of the electric automobile can be increased are achieved; and the automobile body exterior trimming parts are detachably connected with the automobile body framework, so that the automobile body exterior trimming parts are convenient to replace.
