Document Type and Number:
WIPO Patent Application WO/2021/107324
Kind Code:
A1
Abstract:
The present invention provides a motorcycle landing device having a vertically aligned auxiliary wheel, the motorcycle landing device comprising: rotary drivers fixedly formed adjacent to footrests on both side surfaces of a motorcycle, respectively, each rotary driver comprising a DC motor configured to rotate forwards/backwards, a reduction module, and a motor frame for containing the reduction module; first main folding links coupled to both sides of the motor frames to be able to rotate while facing same, respectively, the first main folding links being rotated by the DC motors to predetermined angles; second main folding links rotatably coupled to insides of lower ends of the first main folding links, respectively; auxiliary folding links coupled to lower ends of the motor frames to be able to rotate while facing same, respectively; an auxiliary wheel vertical-alignment link having one side rotatably coupled to insides of lower ends of the second main folding links, the other side of the auxiliary wheel vertical-alignment link being rotatably coupled to insides of the auxiliary folding links, an auxiliary wheel being coupled to the inside of the auxiliary wheel vertical-alignment link; and a fixing frame for fixing the rotary drivers to be adjacent to the footrests. As a result of forward/backward rotations of the DC motors, the first main folding links, the second main folding links, the auxiliary folding links, and the auxiliary wheel vertical-alignment link interwork with one another and thus are folded or unfolded, and when the auxiliary wheel contacts the ground and is separated therefrom, the auxiliary wheel is vertically aligned with regard to the ground.
