Abstract
The utility model belongs to the technical field of the illumination using generator of a bicycle, particularly a band-type brake generator for the bicycle. A magnetic generator is installed in a band-type brake of the bicycle, so the utility model is formed. A permanent magnet is embedded in a wheel of the band-type brake and is used as a rotor of the generator. A magnetic pole of the generator, which is wound with a coil is fixed to the inner part of a band-type brake sleeve and is used as a stator of the generator. The permanent magnet of the rotor is corresponding to the magnetic pole of the stator, and a magnetic pole gap is left. The utility model has the advantages of reasonable design and simple structure. The utility model has integrative function of the band-type brake and the illumination using generator of the bicycle; thus, the utility model can be used as the band-type brake of the bicycle, and the utility model can do power supply for an illumination lamp and an indicator light of the bicycle. If the two output lines of the utility model are short-circuited, the automatic deceleration of the bicycle can be realized.
Description
The utility model belongs to the bicycle lighting technical field of generators, is specifically related to a kind of bicycle band-type brake electrical generator.
In the prior art, the bicycle lighting electrical generator is to adopt magnetic roller induction generation type independent monomer electrical generator that it is installed on the bicycle quick place, and the friction generation electric energy by its electrical generator and bicycle quick adhesive tape uses for the bicycle lighting lamp.The bicycle lighting lamp adopts this kind mode to power, and to the wheel rim wearing and tearing aggravation of bicycle, influences the service life of bicycle, should not advocate.
The purpose of this utility model provides a kind of bicycle band-type brake electrical generator that integrates bicycle band-type brake and bicycle lighting usefulness generator function, and this product promptly is the band-type brake of bicycle, can give the power supply of bicycle lighting lamp again.
The utility model is achieved in that bicycle band-type brake electrical generator is mag-dynamo to be installed constitute in existing bicycle band-type brake.Be about to permanent magnet and be flush-mounted in the band-type brake wheel rotor, the generator magnetic pole of winding around is fixed in the band-type brake cover stator as this electrical generator, and the permanent magnet of rotor is corresponding with the magnetic pole of stator, between permanent magnet and the magnetic pole magnetic pole gap is arranged as this electrical generator.
The utility model is reasonable in design, and is simple in structure.Because the rotor of this electrical generator promptly is the brake wheel of bicycle band-type brake, so,, give illuminating lamp, indicator lamp power supply as the power supply of bicycle lighting and indication usefulness as long as wheel just has electric energy to produce.The utility model also has the function (being the energy consumption braking) of electric braking simultaneously.When the bicycle descending, if think limited speed, need only two output line short circuits with this motor, owing to the mutual action of induced potential, just can realize the automatic deceleration of bicycle.The installation of installation adjustment of the present utility model and existing bicycle band-type brake is adjusted identical.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the distributed architecture scheme drawing of magnetic pole of the stator of the present utility model.
Among the figure, 1 is the band-type brake outer cover.2 are the band-type brake wheel.Permanent magnet 5 usefulness epoxy resin 11 are packaged in band-type brake wheel 2 interior rotors as this electrical generator, and the generator magnetic pole 3 usefulness screws 10 of winding around 4 are fixed tightly in band-type brake cover 1 interior stator as this electrical generator.The generator magnetic pole 3 of winding around 4 circularizes and is distributed in the band-type brake cover 1, and permanent magnet 5 is distributed in the band-type brake wheel 2 with also circularizing, and the permanent magnet 5 of rotor is corresponding with the magnetic pole 3 of stator, between permanent magnet 5 and the magnetic pole 3 magnetic pole gap 8 is arranged.6 is the band-type brake brake rubber block, and 7 is band-type brake lock hoop, and 9 is band-type brake lock crack.Permanent magnet 5 and magnetic pole 3 adopt nd-fe-b to make, and magnetic flux density can be up to 16000 Gausses, so generating capacity is strong.Each coil of stator is connected in series from beginning to end, and induced potential is the summation of each coil-induced electromotive force.Be connected with bicycle lighting lamp, indicator lamp by lead.When wheel, be flush-mounted in the coil on the generator unit stator magnetic pole in the band-type brake outer cover, will the magnetic line of force that permanent magnet produced of rotor be cut, make induced potential in the coil, make illuminating lamp, indicator lamp get electroluminescence.
