The invention discloses a displacement vehicle which comprises a vehicle body and a moving bed plate mechanism, wherein the vehicle body is provided with a lifting mechanism; universal foot wheels aremounted on the vehicle body; the moving bed plate mechanism is used for receiving and transporting patients in a transversely moving manner; the moving bed plate mechanism is mounted on the frame ofthe vehicle body; the moving bed plate mechanism comprises a cloth coiling shaft frame, a cloth coiling shaft, an end connector base, an upper moving plate, lower moving cloth, a lower moving plate, lower moving cloth, a first chain wheel assembly and a ratchet wheel assembly. The displacement vehicle is characterized in that due to arrangement of the first chain wheel assembly, the ratchet wheelassembly and a first chain wheel motor, a conventional transmission mode that a clutch gear, a long rack, a clutch and a clutch driving mechanism cooperate with one another is replaced, the transmission structure of the moving bed plate mechanism is greatly simplified, the displacement vehicle is compact in structure and smooth in transmission, meanwhile, operation of the displacement vehicle is humanized, and positions of the patients can be corrected in necessary.
