Description

Bicycle generating set

Technical field

The utility model relates to a kind of bicycle, relates in particular to a kind of bicycle generating set.

Background technology

Under the situation about reducing day by day along with the global warming and the energy, carbon reduction has become each target of being pursued of the whole world.And bicycle is because light and meet the environmental protection demand, and can make the sport and body-building instrument, so become the present most popular vehicle.

Inferior pressing because bicycle belongs to a kind of light-duty vehicle, therefore always relegated to the category of things wanting for the illumination equipment of automobile, motor bike indispensability; Only look into, the ratio of the traffic accident of bicycle generation in recent years day by day improves.Further investigation reveals that its major cause promptly lacks active illumination and alarming device because of bicycle, cause it easily to be ignored in advancing by automobile, motor bike, and accidents such as generation side swipe.Be with, Ministry of Communication for improving traffic safety, the regulation bicycle must be forced the active light equipment of installing.

Only look into, be used in the active light equipment of bicycle at present, many different modes are arranged, now respectively explanation as after;

1, modal is that inside is equipped with battery, or directly is locked in or is stuck in commercial power charged light-emitting device on the front vehicle frame or back vehicle frame of bicycle, the ON/OFF or the flicker of the controlling switch lamp light on the light-emitting device; Only look into, as utilize the method for battery as electric power source, because of must often changing battery in the use, cost height not only, and be not inconsistent the environmental protection demand.Moreover, as with commercial power charged light-emitting device, be not conveniently in the use, therefore more impracticable.

2, another kind of method is to utilize cyclery to come in as the propulsion source of generating, it is to connect a drive wheel in the outside of a small generators, utilize this drive wheel to abut on the tire or the rotating shaft of right overhead on, with the gyroscopic movement of this tire or right overhead and then drive the drive wheel rotation of this electrical generator.Only looking into, in the recline mode of tire of the drive wheel of electrical generator, is to drive drive wheel with massaging way, and the abrasion problem easily takes place in this measure, reduces the service life of tire.In addition, utilizing a driven wheel is set in the rotating shaft of right overhead, driven the mode of the drive wheel of electrical generator again by this driven wheel, is to add driven wheel in the sky in the heart, complicated because assembling is gone up, and is unfavorable for user DIY; Moreover the driven wheel that is installed in right overhead only is subject to the space, so diameter can not be too big, and its rotation speed ratio can't promote thus, causes generating efficiency not good, also is its shortcoming.
