Description
Technical field
The utility model is related to the drive mechanism of cycling, more particularly to a kind of crank of bicycle is up and down reciprocatingly put
Dynamic drive device.
Background technology
Bicycle is one of walking-replacing tool that people like, is also people's amusement and recreation and a kind of mode for taking exercises.
In the last few years, the growing leisurely and carefree demand with healthy adventure in daily life of people promoted bicycle to be taken into full account in design
The factor of human body, while to take into full account the handling characteristics of different crowd and occasion so that the design of bicycle is towards " occupancy is empty
Between less, it is flexibly convenient, it is comfortable durable " the features such as continue to develop.
The drive mechanism that present bicycle is used is to connect two foot-operated and cranks by axis.Process of the people in force
In, the sole of people drives crank to rotate by acting on the power on foot-operated, and the power that sole is acted on foot-operated is with crank
The difference of position, the size and Orientation of its active force is also different, the active force or for along crank radial effect, or to be cut along crank
To effect.Especially when crank turns to the position conllinear with hip joint with thigh, shank, there is " dead point " phenomenon twice, i.e.,
The power that human body is applied on foot-operated is radial load.Now it voluntarily can only change cycling posture by human body to change dead-centre position
So as to continue to move derived from driving.And now to apply because bicycle saddle position relative to the position of crank is constant
One forward tangential component of driving bicycle is relatively difficult.Therefore, either personally body bends one's legs or body is moved back by bicyclist
Some distances are moved, so that sole deviates certain angle to produce the component of horizontal direction to riding, simultaneously because some saddles
The need for the arrangement of position does not meet organization of human body function yet, bicyclist is easy to produce fatigue.
The content of the invention
The purpose of this utility model be to overcome the shortcoming and defect of above-mentioned prior art there is provided one kind it is simple in construction, drive
