Lightweight electric automobile body structure

A lightweight electric automobile body structure comprises a frame, an automobile body, a motor, suspensions, front wheels and rear wheels, wherein the frame is of an integrated frame structure formed by welding aluminum alloy sectional material and plates, the motor, the suspensions and the automobile body are all installed in the frame, the frame is connected with the wheels through the front suspension and the rear suspension, screw holes for fixing the automobile body are formed in the frame, and a base for fixing springs is arranged on the frame. The automobile body is good in comfort, and the comfort of a passenger in an automobile can be improved. The motor is not directly fixed to the automobile body, and noise is not prone to being transmitted into the automobile; the longitudinal rigidity of the whole automobile is high; various kinds of impact transmitted to the automobile body from a pavement can be relieved, and the service life of the automobile body is prolonged; when the automobile collides with another automobile, part of impacting energy can be absorbed by the frame, and the safety performance is improved; the automobile body bearing coefficient is small, and development of a deformation automobile is facilitated; a chassis and the automobile body serve as assemblies to be assembled in advance, and the assembly process of the whole automobile is simplified.
