The invention relates to a multifunctional vehicle lifting, steering, moving and obstacle-crossing device which consists of a rotating mechanism, a lifting mechanism, a driving mechanism and a control mechanism. The multifunctional vehicle lifting, steering, moving and obstacle-crossing device is mounted at the bottom of a vehicle; when not used, the multifunctional vehicle lifting, steering, moving and obstacle-crossing device can be very conveniently folded at the bottom of the vehicle, has the characteristics of portability, flexibility, no space occupation and easiness in operation, and can manually or automatically realize functions of lifting, rotating, moving and the like of the vehicle by a wired or wireless control mode; the defects that only forwarding, backing and left front, left rear, right front and right rear steering driving can be realized in the existing vehicle design, and four-wheel off-ground running, whole vehicle lateral moving, in-place rotating, narrow pavement passing, wider ditch crossing and higher narrow body obstacle passing cannot be realized are effectively overcome; the maneuvering characteristic of the vehicle is improved, and particularly the whole vehicle lifting, all-round steering and moving and obstacle passing capacity is improved; such harder tasks as parking, moving, turning around and turning a corner of the vehicle in a narrow space and ditch passing of the vehicle can be better completed.
