Abstract
A chassis for an electric vehicle comprises: a base frame, a front frame, a rear frame, two side frames, four suspension devices and four wheels. The front frame and the rear frame have the front arc-shaped tube and the arc-shaped rear tube fixed to the base frame, the arc-shaped tubes can not only reduce the number of tubes required but also increase the area of thrust force as compared to the straight tubes. Besides, the arc of the arc-shaped tubes avoids a connection point of an acute angle. Moreover, the height is larger than the width, which will produce less torque on the base frame as compared to that if the height is smaller than the width, thus preventing the torque acted on the base frame from damaging the connection points and improving the structural strength of the chassis at the connection points.
