Title:
CIRCULAR RECIPROCATION CONVERSION MECHANISM FOR BICYCLE
Document Type and Number:
WIPO Patent Application WO/2020/000566
Kind Code:
A1
Abstract:
Disclosed is a circular reciprocation conversion mechanism for a bicycle. The circular reciprocation conversion mechanism comprises two discs (1, 2) with opposite centers, and a transmission shaft (3) arranged between the two discs (1, 2) and parallel to the direction of a disc surface. The two discs (1, 2) are rotatably arranged on a connecting rod (5); a rotary handle (10, 20) is provided on each of the discs (1, 2); and raised teeth (6) are circumferentially distributed on an inner side surface of each of the discs (1, 2). The transmission shaft (3) is arranged in the direction of the diameter of the circular discs (1, 2) and is sleeved with a first gear (41) and a second gear (42). The first and the second gear (41, 42) are respectively connected to the transmission shaft (3) via two one-way transmission structures with opposite transmission directions, and the first and the second gear (41, 42) respectively engage, at front and back ends of the discs (1, 2), with the raised teeth (6) on the inner sides of the discs. A drive force is generated by converting the up-and-down reciprocating motion of pedals (11, 12) into the circumferential motion of the transmission shaft (3) so as to drive a bicycle to move forward. Conventional circumferential motion is replaced by reciprocating motion, such that unnecessary work can be reduced, thereby saving on the physical strength of a user.
