The invention discloses an intelligent garage car moving device based on a single chip microcomputer. The intelligent garage car moving device is mainly composed of a car carrying plate, a stereo frame, a shuttle vehicle and a car storage plate, wherein the car storage plate is arranged in a building structure, the car carrying plate is located outside the building structure, and the shuttle vehicle is located on the car storage plate and mainly consists of a driving motor, a lead screw, a car lifting plate, a supporting rod, a pull rod driving mechanism, rollers, guiding wheels, a car lifting motor, a speed reducer, an output shaft gear, guiding wheels and a rack. The car lifting motor drives the lead screw to rotate, drives the pull rod driving mechanism and the car lifting plate to move, the supporting rod below the car lifting plate rotates around a supporting point, and accordingly the car lifting plate performs a car lifting action. The driving motor drives the output shaft gear to rotate and drives the shuttle vehicle to perform transverse movement through meshing motion of the output shaft gear and the rack. The device achieves transverse movement of the car through back and forth shuttling between the car storage plate and the car carrying plate of the shuttle vehicle and achieves the two processes of going in or out of a garage of vehicles in the stereo garage.
