Description

Booster bicycle pedal

Technical field

The present invention relates to the bicycle pedal technical field, refer in particular to a kind of pedal of mini-motorcycle.Mini-motorcycle promptly is the multi-functional morpet that has manpower driving, power driven or manpower driving and power driven and usefulness simultaneously.

Background technology

Morpet is easy to use, is provided with three kinds of functions of riding of manpower driving, power driven or manpower driving and power driven and usefulness, has become the important vehicle of day by day popularizing.During power driven, both feet are in resting state, at the problem of how to shelve both feet, in the patent No. is 200420003399.0 patented technology scheme, provide a kind of bicycle pedal body of using to switch the booster bicycle pedal that the left-right symmetric, traveling comfort and the safety that constitute meet mechanics of human motion's engineering.But this pedal is in use, has following problem and defective:

1. switch to pedal state from the pedal state, earlier by hand traction, step on locking by pin again and finish, such design plan has influenced the agility of blocked operation;

2. extracting of shank is that cross handle by shank moves along the projection on the tongue box outer wall and finishes in the mechanism of pulling pin of this technical scheme, the location of left side crank is the telescopic tongue snap-lock and finishing mutually in inboard and the casing of side crank of keeping left, be that it extracts shank and the locking crank is sub-unit, a separation structure complete operation alone, with and design plan such as trailer coupling, increase on the one hand the quantity of related components, in use caused the part sequence of operations obstacles such as difficulty that easily block, reset on the other hand;

3. prizing in the mechanism in this technical scheme, the ripping bar and the right side crank that are provided with the bar head are fixed as an integral body in the axis both sides, the bar head promotes the upset of upset tongue in upset hypogloeeis side, after this manner, if make the ripping bar that is provided with the bar head and right side crank all place the right outside of sprocket wheel, the ripping bar that is provided with the bar head that exposes when then car body switches to the pedal state has destroyed normal foot-operated riding, and has promptly destroyed the independent completion of pedal state;

4. in this technical scheme, when switching to pedal state, adopted the technology of standard bicycle captive joint between sprocket wheel and the axis, can affect the retrograde rotation simultaneously of sprocket wheel and axis during the wheel antikinesis, the car body associated components can be broken the parts state at random into non-pedal state, non-pedal state automatically, thereby seriously having reduced practicality, the car body that switches to pedal state can not antikinesis, causes pedal state not have independent completion;

5. outside part is exposed in this design plan, destroyed the practicality of car body and attractive in appearance to a certain extent.

Therefore, be necessary to develop new technical scheme, to overcome the deficiencies in the prior art and defective.
