When the mobile unit rotates to the rotation starting position, the rotation reset detection element sends a signal to trigger the parking equipment control system to stop the operation of the motor of the straight-moving side motor reducer of the mobile unit, and the rotation of the mobile unit is stopped.

The third step: the parking equipment control system outputs signals to enable a power switch of a motor at the rotating side of the mobile unit to be in a conducting state, the output signals enable a motor of a motor reducer at the rotating side of the mobile unit and a motor of a motor reducer at the straight-moving side to rotate in opposite directions, a driving roller at the rotating side of the mobile unit and a driving roller at the straight-moving side are driven to rotate in opposite directions, a component at the rotating side of the mobile unit and a component at the straight-moving side are driven to move backwards synchronously, and therefore a bedplate main body is driven to move backwards in a follow-up mode through a positioning component at the rotating side of the upper bedplate; in the backward moving process, the rotating side assembly obtains the guiding and positioning of the rotating side ground guide rail, the guide roller, the rotating side auxiliary positioning component and the guide groove of the rotating side longitudinal beam, and the straight side assembly obtains the guiding and positioning of the straight side auxiliary positioning component and the guide groove of the straight side longitudinal beam.
