Unmanned vehicle with liftable loading platform

The unmanned vehicle comprises a chassis frame and the loading platform, the chassis frame comprises two columns of longitudinal beams and a cross beam arranged between the two columns of longitudinal beams, a platform lifting area is formed between the cross beam and the two columns of longitudinal beams, and the loading platform is arranged in the platform lifting area. And a lifting mechanism for driving the loading platform to lift is arranged on the longitudinal beam. The lifting mechanism can drive the loading platform to penetrate through the chassis frame of the U-shaped structure to achieve lifting, the loading platform can descend to the ground or be in butt joint with platforms of different heights, unloading can be achieved without the help of a forklift, the cost for purchasing the forklift and matched forklift operators is saved, the unloading process is simplified, and the unloading efficiency is improved. The two sides of the loading platform are connected with the two columns of longitudinal
