A lightweight chassis structure comprises an aluminum frame, a front steel frame and a rear steel frame, wherein the front steel frame is located below the front side of the aluminum frame, and the rear steel frame is located below the rear side of the aluminum frame. The aluminum frame comprises a main beam and a cross beam, wherein the main bean extends in the length direction, and the cross beam is perpendicular to the main beam and extends in the width direction of the aluminum frame. The rear steel frame comprises a rear steel frame main beam and a connection rod, wherein the rear steel frame main beam extends in the length direction of the rear steel frame, and the connection rod extends in the width direction of the rear steel frame. The connection rod is fixedly connected with the main beam of the aluminum frame. The front steel frame comprises a front steel frame main beam and a connection plate, wherein the front steel plate main beam extends in the length direction of the front steel frame, and the connection plate extends in the width direction of the front steel frame. The connection plate is fixedly connected with the main beam of the aluminum frame. The lightweight chassis structure is compact and reasonable, overall strength is enough, the chassis structure is low in weight, and the weight of a whole automobile is reduced; besides, a modular production mode can also be adopted, and production efficiency is improved.
