Title:
MULTI-DEGREE-OF-FREEDOM BICYCLE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/221722
Kind Code:
A1
Abstract:
A multi-degree-of-freedom bicycle and a control method therefor. The solution comprises a bicycle body (1), a front driving frame (2) used for driving a front wheel (11) of the bicycle body (1) to rotate, and a back supporting frame (3) used for supporting the bicycle body (1); a back wheel (13) of the bicycle body (1) is in a suspended state, and the front wheel (11) of the bicycle body (1) is arranged at the top of the front driving frame (2), so that the front wheel (11) can rotate on the front driving frame (2) and move along with rotation of a handlebar (16) of the bicycle body (1); the front driving frame (2) is in communicational connection with the bicycle body (1) so as to keep the rotating speeds of the front wheel (11) and the back wheel (13) to be the same; the back supporting frame (3) is connected to the bicycle body (1) by means of a universal joint (6), the center of the universal joint (6) coincides with the center line of the bicycle body (1), and the left side and the right side of the universal joint (6) are each provided with an elastic adjuster (7); each elastic adjuster (7) is connected to the bicycle body (1) and the back supporting frame (3) so as to provide an elastic buffer function, and each elastic adjuster (6) can adjust the elastic stroke to change the magnitude of elastic buffer force. The solution has the effects of implementing multi-degree-of-freedom adjustment of the bicycle body and better simulating real riding experience.
