The invention discloses an electric automobile chassis system which comprises an automobile frame, an automobile frame widening device, a walking steering device, a turnover trunk and a turnover trunk driving mechanism. The vehicle frame widening device comprises two widening plates slidably mounted on the two sides of the automobile frame correspondingly, a linear moving mechanism used for driving the two widening plates to stretch out and draw back, and a first driving mechanism connected with the linear moving mechanism. The walking steering device comprises a plurality of walking wheels installed on the widening plate, a steering transmission mechanism used for driving the walking wheels to steer synchronously and a second driving mechanism connected with the steering transmission mechanism, and the steering transmission mechanism comprises a first transmission assembly, a linkage rod and a second transmission assembly. The structure is simple, the purpose of widening the automobile frame can be achieved, the synchronous steering precision of the walking wheels can be improved, the walking stability of the electric automobile after the automobile frame is widened can be guaranteed, manual control over the turnover trunk can be achieved, and the safety of movement of the turnover trunk can be enhanced.
