Automatic parking device of bicycle
An automatic parking device of a bicycle comprises a front wheel groove used for containing a front wheel of the bicycle and transmitting the pressure of the front wheel of the bicycle downwards, a self-locking component hinged to the lower portion of the front wheel groove and capable of achieving self-locking at the lower position and releasing at the upper position alternately under the downward pressure of the front wheel groove, a lever mechanism hinged to the self-locking component, and a rear wheel clamping disc used for clamping a rear wheel of the bicycle, hinged to the other end of the lever mechanism, and capable of moving in a direction opposite to the vertical moving position of the self-locking component through the lever transmission function of the lever mechanism. When the front wheel of the bicycle presses the front wheel groove, the self-locking component is pressed to move downwards and is self-locked at the lower position, and meanwhile, the rear wheel clamping disc is ejected through the lever mechanism and clamps the rear wheel of the bicycle; when the front wheel of the bicycle presses the front wheel groove again, self-locking of the self-locking component is relieved, the self-locking component returns to the upper position, and meanwhile, the rear wheel clamping disc is pulled down through the lever mechanism and is disengaged from the rear wheel of the bicycle. The automatic parking device of the bicycle is simple in structure, convenient to operate, and capable of achieving automatic parking. 1.
