Abstract

The utility model relates to a clutch planetary accelerating electric generator for bicycle; a permanent magnet claw-pole generator is arranged in a special front hub of the bicycle ; when the electricity is generated, a magnetic field stator rotates synchronously with a front wheel with a front wheel shaft of the bicycle as the center to drive a coil rotor provided with an iron core through a planetary accelerator to be simultaneously rotated in the opposite direction, thus achieving good effect of generating the electricity. Because new high-performance magnetic materials, the new planetary accelerating structure and the simple and reliable clutch device are adopted, the utility model can be used conveniently, saves labors, has good effect of generating the electricity, is an ideal illumination and light signal device for the traveling of the bicycle at night, can be used forming a complete set with various bicycles and can put an end to the happening of some traffic safety accidents.

Description

Bicycle use disengaging type planet acceleration generator

The utility model relates to a kind of power generation assembly, mainly being used in alternative bicycle front axle skin is installed on the bicycle front-wheel, when travelling by bike night, by moving the on-of pin handle, just can obtain both laborsaving, effective illumination and wigwag, for safety traffic provides guarantee, can with the supporting use of all kinds of bicycles.

Present known dynamo lighting set optical illumination generally adopts dynamo-powered lamp, because structure is limit too effort, effect is undesirable, is difficult to apply, and the utility model is that a kind of electric organ is placed in the special front axle friend of bicycle, rotates by front-wheel and generates electricity.

The utility model provides a kind of power generation assembly of bicycle use, and it not only generates electricity effective, and easy to install very laborsaving, and bicycle is not had any wearing and tearing.

The purpose of this utility model should realize like this, on the bicycle front axle skin outer casing inner wall of special non-magnetic conduction, lay a plurality of stator permanent magnet magnetic poles, lay a gear ring simultaneously, the electric organ rotor adopts the multipole pawl utmost point, in install coil, at the rotor claw utmost point one end sun gear is housed, rotor is enclosed within on the bicycle front wheel spindle, can rotate freely, when bicycle running, front-wheel rotates and stator field, and gear ring rotates, and gear ring is by the planet tooth simultaneously, drive centre tooth again and make pawl utmost point rotor and stator field do reversing sense acceleration rotation, cutting magnetic field reaches the purpose of generating.

Because when bicycle generally travels, the spin velocity of front-wheel is very little, the stator field rotation cutting iron-core coil rotor of depending merely on the bicycle front axle skin outer casing inner wall is difficult to generating, therefore install the planet accelerator additional, just will speed up device external toothing and stator permanent magnet magnetic pole, be fixed on simultaneously on the bicycle front axle skin outer casing inner wall, when the bicycle front-wheel rotates, the also synchronous equidirectional rotation of stator stationary magnetic field and accelerator external toothing, drive the rotation of planet accelerating gear by external toothing and drive the acceleration rotation that the centre tooth crop rotation that is fixed on rotor one end and external toothing are bicycle front-wheel direction of rotation again, so also relative cutting speed in feet per minute obtains comparatively ideal generating effect between electric organ stationary magnetic field and the coil rotor with regard to having improved.

The clutch mode, the planetary wheel of electric organ is that being fixed on the bicycle front wheel spindle is the center, on the rotatable supporting plate, when on-of pin inserts, fixing planetary supporting plate just maintains static, external toothing only drives planetary wheel and rotates, driving sun gear acceleration rotation again is rotor rotation, at this moment electric organ is in generating state, when on-of pin is extracted out, external toothing not only drives planetary wheel and rotates, and also drives the planetary gear carrier plate simultaneously and rotates, and at this moment just can not to rotate be that rotor does not rotate electric organ and is in not generating state to sun gear again.

The labour-saving principle, because this electric organ is to be the center with the bicycle front wheel spindle, its resistance is the magnetic field force between stator field and the rotor, magnetic pole adopts high performance magnetic material, so the magnetic field diameter of stator bore is very little, and the magnetic field resistance is very near apart from front wheel spindle, the stressed strong point is the bicycle front wheel spindle, as the force is the front-wheel radius, because front-wheel radius ratio magnetic field diameter of stator bore is big tens times, though it is also very laborsaving that the planet accelerator is housed.

Comprehensive above-mentioned the utility model is that shell becomes special bicycle front axle skin with non-different magnetic material, with the bicycle front wheel spindle is the center, the magnetic field stator rotates synchronously with the bicycle front-wheel during generating, drives a permanent magnet generator of cored coil rotor reversing sense acceleration simultaneously rotation again.Its technical characterictic is: this electric organ is manufactured with the speed that the planet accelerator improves the coil cutting magnetic field and reaches desirable generating effect, uses the fixing and rotation of on-off planet gear stand plate to reach generating and the purpose of not generating electricity simultaneously.

The present matching used dynamo-powered lamp of Regular Bicycle, be that generation 30 or 40 years is by American-European countries input China, it is with the cycle casing transmission that rubs, drive the generating of power generation assembly magnetic field rotor rotation cutting iron-core coil, because its structure is limit, require the cireular frequency of cycle casing rotation that certain generating effect must just can be arranged greatly, otherwise just not all right.Require the big driving efficiency of friction force just high simultaneously, therefore quite require great effort, also bigger to the cover tire wearing and tearing, the road mud is muddy can not to be used, and this has just restricted promoting the use of of dynamo-powered lamp.

Bicycle use disengaging type planet acceleration generator, with existing dynamo-powered lamp relatively, maximum characteristics are that the former is laborsaving, effective, also good effect can be arranged when low speed driving, it is muddy not to be afraid of the road network mud that rains, and bicycle is not had any wearing and tearing, use is easily only moved the on-of pin handle and is got final product, and these are that existing dynamo-powered lamp is unrivaled.
