Principle of operation

(1) Parking process of the parking device

When parking, firstly, the vertically arranged long connecting rod 12 is pulled down to the horizontal position, the front wheel and the rear wheel of the bicycle are fixed on the connecting rod parking frame through the hook 11 and the baffle 13, the handlebar is slightly lifted upwards to start the folding of the connecting rod mechanism, and the force required at the moment is the largest and is about half of the weight of the bicycle. The boosting effect of the gas spring 17 is gradually increased along with the lifting of the bicycle until the bicycle is in a critical state, and the bicycle is automatically parked in place, so that the vertical parking is realized.

(2) Rotation process of the parking device

By holding the bicycle cross or seat, or the long link 12, a transverse force is applied to drive the entire parking device to rotate around the turntable bearing 22.

(3) The parking device takes the car

When the bicycle is taken, one hand holds the handlebar, the other hand holds the bicycle seat and slightly pulls the bicycle backward, and the bicycle can slowly and stably fall to the horizontal position under the action of the self gravity and the air spring 17. Then the handle bar is rotated rightwards, the front wheel of the bicycle is separated from the hook 11, the rear wheel is separated from the baffle 13, finally the hook 11 is pulled up, the connecting rod parking frame is automatically folded upwards under the action of the air spring 17, and the whole bicycle taking process is completed at the moment.

The present invention is not limited to the above embodiments, and any person skilled in the art can make many modifications and equivalent variations by using the above-described structures and technical contents without departing from the scope of the present invention.
