Auxiliary power starting structure of electric bicycle

Abstract

The present invention relates to an auxiliary power starting structure for electric bicycle. At the moment when the pedal of bicycle is stepped by rider, the crank can be rotated, and the chain wheel also can be rotated, in this course the actuator can be moved towards shallow end direction from deep end of stepped slideway, when the actuator is positioned in the shallow zone, the contact disk can be extended outwards to trigger switch and make it output auxiliary power.

Description

technical field [0001] The invention relates to an auxiliary power starting structure of an electric bicycle, especially when the user exerts force to step on the electric bicycle to move forward, the electric bicycle can mechanically start the auxiliary power to drive the bicycle from the user's pedaling force. Background technique [0002] For modern times that pay more and more attention to environmental protection, electric bicycles are environmentally friendly vehicles that comply with no exhaust pollution. Because of their easy operation, they are widely loved by users of all ages; There are many different starting timings and control methods, such as: [0003] In the earliest days, a control switch was installed on the handle of the bicycle for the user to directly control, but the operation must be controlled by hand, which is not convenient to operate and not practical; therefore, there is a Japanese patent application No. 2001-055399 No., which detects the driving...

Problems solved by technology

[0006] However, as mentioned above, they all directly detect the strength of manpower through precise electronic parts and complex detection structures, and then use it as a control auxiliary power output, so not only the cost is high, the components are complicated, and the failure rate is high; and If the electronic components are used as the pedal force judgment point, there will be a problem of misjudgment. For example, since electric bicycles are applicable to a wide range of objects and age groups, the pedal force presented by different users is naturally different. If the pedal force If the setting is too heavy, it will be difficult to operate, and if the pedal force is set too light, there will be a risk of false touch;
