The invention discloses a chassis structure of a suspension frame electric vehicle. The chassis structure comprises a frame. The frame is provided with a plurality of sets of independent walking devices. Each walking device comprises a control system, a hanging motor, a cantilever, wheels and a power motor, and a containing frame is arranged on the top of the frame. The control systems are arranged in the containing frame. A cantilever shaft fixing frame is arranged at the bottom of the frame and connected with cantilever shafts in the horizontal direction through longitudinal rotating bearings. The upper ends of the cantilevers are connected with the cantilever shafts. The cantilever shafts are connected with output shafts of the hanging motors through transmission gear sets. The lower ends of the cantilevers are connected with the wheels. The power motors are hub type power motors installed on the wheels. Compared with the prior art, the chassis structure has the advantages that during driving, the wheels can be automatically lifted up or placed down through a vehicle chassis when the ground is bumped or oblique, and the wheels are kept to make contact with the ground; the vehicle body part is kept horizontal constantly, and the gravity center is in the safety range all the time.
