After the backing plate 11 is stretched in place (at this time, the total width of the backing plate can be used for the wheels on both sides of the car to pass by simultaneously), the lower sensor 22 feeds back a signal to make the green light of the remote controller turn on.

Align the wheel with the pad and drive straight across, drive a short distance after crossing the obstacle (make sure the rear of the car is in front of the pad), and stop.

Press the shrink button of the remote control, the two-way motor and the rope reel 19 rotate in the opposite direction, and the left and right sliders 13 are pulled by the guide rope 14 around the fixed pulley 12 and slide inward along the slider guide rail 20 at the same time, the left and right sliders 13 Respectively push the left and right backing plates 11 to shrink inwardly along the backing plate guide rails 18 . After the backing plate 11 shrinks in place, the lower sensor 22 feeds back a signal to make the yellow light of the remote controller turn on.

Press the board closing button of the remote controller, the rear locking device 2 is opened immediately, and the winch 5 starts to draw in the rope. The steel wire soft rope 1 pulls the automatic retractable backing plate to move forward and upward, the front end of the backing plate support 16 is gradually lifted off the ground, and the rubber wheel 17 at the rear end of the backing plate support 16 is rolling on the ground to prevent the anti-skid and anti-fall layer at the bottom of the backing plate support 16 21 is worn out; along with the continuous pulling of steel wire soft rope 1, the backing plate support 16 front ends of arc shape are dragged in the bell mouth that left and right rail 4 rear ends form; Roll below the top plate 8 of the plate, and the track pulley 3 on the outside of the track 4 and the bottom edge starts to rotate one after another; the front end of the backing plate support 16 with elasticity is slightly bent, and the soft rope 1 moves along the middle seam below the spring track 10, gradually moving the Powerful spring 9 compresses, and the rubber wheel 17 of backing plate support 16 rearmost end leaves the ground finally, and automatic telescopic backing plate is dragged back in the track 4 below the automatic hoisting board device fully. After the automatic retractable backing plate returns to its original position completely, the upper sensor 22 feeds back a signal to make the red light of the remote controller turn on.

Press the locking button of the remote controller, the front and rear locking devices 2 are locked together, and the automatic retractable backing plate is locked; at the same time, the winch 5 loosens the rope, and the strong spring 9 promotes the steel wire soft rope 1 to return automatically along the spring track 10. The car is ready to drive away.
