a bicycle

Abstract

The present invention relates to a bicycle, comprising a frame, a wheel, a drive mechanism arranged on the frame, a flywheel assembly arranged on the wheel, a transmission mechanism connecting the drive mechanism and the flywheel assembly, and a drive mechanism arranged on the A footrest on a driving mechanism; the driving mechanism includes a slide rail, a sliding block sliding along the sliding rail, and a driving reset structure for realizing the reset of the sliding block, and the footrest is fixed on the sliding block. The bicycle provided by the present invention obtains a bicycle with a new driving structure through the arrangement of the driving mechanism, the flywheel assembly and the transmission mechanism. When driven by external force, it can simply move in a straight line, the driving efficiency is high, and the size of the frame is not affected by the driving mechanism. The size limit of the bicycle can be set as required, the height of the frame can be reduced, the center of gravity of the user can be lowered, the safety performance can be improved, and the traditional bicycle frame can also be used to save production costs.

Description

technical field [0001] The present invention relates to the technical field of bicycle equipment, in particular to a bicycle. Background technique [0002] At present, the existing bicycles use the sprocket to drive the chain to rotate, and manpower needs to drive the sprocket to rotate through circular motion, so as to realize the advancement of the bicycle. For bicycles with this driving method, due to the circular motion of manpower, part of the force is decomposed. Useless work leads to low driving efficiency of the bicycle. On the other hand, due to the structural limitations of the sprocket and pedals, the size of the bicycle cannot be designed arbitrarily, so people of different heights can only choose bicycles of corresponding sizes, which has poor versatility. [0003] Finally, limited by the size of the bicycle itself, the user's center of gravity is relatively high, and the safety is not high, and the user must apply force from the top to the bottom, and the seat ...

Problems solved by technology

[0002] At present, the existing bicycles use the sprocket to drive the chain to rotate, and manpower needs to drive the sprocket to rotate through circular motion, so as to realize the advancement of the bicycle. For bicycles with this driving method, due to the circular motion of manpower, part of the force is decomposed. Useless work, which leads to low driving efficiency of the bicycle. On the other hand, due to the structural constraints of the sprocket and pedals, the size of the bicycle cannot be designed arbitrarily, so people of different heights can only choose bicycles of corresponding sizes, which is poor in versatility

[0003] Finally, limited by the size of the bicycle itself, the user's center of gravity is high, the safety is not high, and the user must apply force from the top to the bottom, and the seat is not comfortable enough
