Description

Bicycle generating set

Technical field

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

Background technology

The ride night general mood of bicycle of people is very in vogue, decorates at night at some an array of stars and gentle bright moonlight, is gently stepping on the bicycle person and is travelling everywhere, and the cool breeze in evening sweeps the hubbub and the pressure on daytime, allows the people unfold the surplus of muscles and bones and thinks that more soul is easily happy.

But ride because of having lacked daytime illumination at night, rider's range of visibility and visbility obviously weaken, identification to road conditions is greatly affected with the grasp nature, add and ride previous night only according to vehicle frame, the reflection alarming of fraction is sent a car on the car clothing, not only passive but also difficult receipts are good imitates, therefore for the warning lighting light that substitutes natural daylight is provided, promptly the someone releases bicycle generating set for this reason, producing electric power when moving by bicycle synchronously uses for the warning lighting device, and existing bicycle transmitting apparatus normally is provided with cycle wheel hub position, yet this kind mode is twined quantity because of the too small limit coil in space is set, and then influence generating efficiency, continuous design of consulting TaiWan, China patent application case number No. 093206971 " power generation assembly of bicycle Warning light ", it is the place that is coupling that is located at the pedal crank and the transmission shaft of bicycle, include: a coil assembly is set on the transmission shaft periphery, and is fixed on the skeleton of bicycle and forms stator; One rotating disk, be fixed in transmission shaft, when pedal and crank drove transmission shaft, rotating disk can be with transmission shaft interlock rotation formation rotor, this rotating disk has the recess of receiving and is positioned at the coil assembly outside, and the recess of receiving wall on every side is embedded with several with the staggered magnet assembly of N/S; Utilize pedal to drive transmission shaft and when rotating, rotate in the coil assembly periphery with the recess of receiving of seasonal rotating disk, and then move around coil assembly, make coil assembly produce power supply by magnet assembly through crank, with this supply coupling on Warning light, even Warning light is luminous.

Aforementioned is to be another existing bicycle generating set, though it can produce the effect of generating by the rider in the treadled cycle process, yet it has following shortcoming:

1. it is the place that is coupling that is located at the pedal crank and the transmission shaft of bicycle, be five-way pipe both sides to the gap between crank, and the space at this position of bicycle is quite narrow and small, its purpose is to provide the user to be convenient to drive, if power generation assembly is located at narrow space like this, be that relative limit coil twines quantity, and can't make high-power generating effect.

2. continuous by aforementioned concepts as can be known, if with the generated output be purpose and increase coil quantity by force, then essential relatively Extensible pedal crank and the transmission shaft space at place that is coupling, and then cause the crank width increasing of bicycle both sides and influence and drive convenience.

3. aforementioned existing bicycle generating set is to present to expose aspect, is subject to expose to the sun and rain and causes structure to damage, and easily attach dust and influence the running generating efficiency.

No matter aforementioned existing bicycle generating set is the place that is coupling that is located at wheel hub or pedal crank and transmission shaft, all having coil is provided with insufficient space and influences generating efficiency, existing its generating efficiency of power generation assembly is only between 5A～10A, if will be can the generated output that must surpass 70A then being arranged at least as the power of demand as electric power storage, therefore existing bicycle generating set only can be applicable to the application of miniwatt electrical equipment such as light-emitting device, if desire as electric power storage with the application as Electrical Bicycle, its generated output then is not inconsistent demand far away.
