The invention relates to a deformation jacking mechanism for an automobile/robot. The deformation jacking mechanism for the automobile/robot comprises an upper robot body rear shell, a lower robot body rear shell, a pedestal, a driving mechanism, a transmission mechanism and a jacking mechanism; the upper robot body rear shell is rotatably connected with the lower robot body rear shell; the pedestal is fixed on the lower robot body rear shell; the driving mechanism is arranged inside the upper robot body rear shell; the transmission mechanism is arranged on the pedestal and in transmission connection with the driving mechanism; the jacking mechanism is arranged on the pedestal and in transmission connection with the transmission mechanism and performs horizontal motion towards two sides under the drive of the transmission mechanism to jack up a left bodywork and a right bodywork of the automobile. The deformation jacking mechanism is used in the automobile/robot, can conveniently deform the automobile into a walking robot, or deform the walking robot into the automobile, and adds new splendor to a robot world.
