Parallel four-rod thin frog leg mechanism and use method

The invention relates to the technical field of bionic frog legs, and particularly discloses a parallel four-rod thin frog leg mechanism and a use method of the parallel four-rod thin frog leg mechanism. Comprising a horizontally-arranged frame, a plurality of sets of supporting arms installed on the side face of the frame and hinged to the frame, a leveling support hinged to the sides, away from the frame, of the supporting arms, and telescopic driving mechanisms hinged to the sides, close to each other, of the leveling support and the side face of the frame respectively and arranged in one-to-one correspondence with the supporting arms. The invention further discloses a using method of the vehicle frame, after the vehicle frame is folded, the occupied space is as small as possible, the requirements of road transportation and railway transportation limits of the vehicle are met, and after the vehicle frame is unfolded, the vehicle frame has good rigidity and can extend out of the vehicle frame by a large siz
