Abstract
The utility model relates to a light-emitting device for bicycles, which does not need batteries. The utility model emits light by using a current generated from relative motion between a bicycle fork and a wheel spoke during the running of a bicycle, without rubbing tyres or increasing the physical strength of a bicyclist. The utility model is composed of a magnet 1, a coil 2 and a light emitting diode 3, wherein the magnet 1 and the coil 2 are respectively fixed on the bicycle fork and the spoke, so that the distance between the utility model and wheel axles of the bicycle is equal. The coil 2 and the light emitting diode 3 are connected by a conducting wire 4. When wheels rotate, the coil 2 cuts the magnetic force line of the magnet 1 to generate a pulse current and glittering light can be emitted by the light emitting diode. The utility model has the functions of night riding identification and decoration.
Description
The utility model is the light-emitting device that uses on a kind of bicycle.
At present when the night running bicycle, for guaranteeing safety, car light often is housed on bicycle, the useful battery of these car lights is as the direct current (DC) illuminating lamp of power supply, also have and utilize the cycle wheel turning effort of tire under steam, the drive electricity that rubs rolls the rotor of electrical generator, and the electric current of generation makes car light luminous.
But, more than in two kinds of car lights, the energy of one consuming cells, cost is high and inconvenient, its two, the muscle power that not only consumes the cyclist simultaneously, also can increase the abrasion of tire.
The utility model is intended to invent a kind of muscle power that neither consumes the cyclist, not abrasion tire again, and do not need to be provided with in addition the bicycle light-emitting device of battery, it only utilizes the bicycle width of cloth bar of wheel and the relative motion between the car fork under steam, can produce electric current, make lamp luminous.
The utility model is such: it is made up of magnet 1, coil 2, light-emitting diode 3 and lead 4.
Wherein magnet 1 is a magnetic links that magnetic-field intensity is higher, and it can be ring-type, circle, microscler, and middle placement soft iron or silicon steel plate are so that magnetic line of force Ji Kou.Can form by one or more magnet.
Coil 2 also can be placed soft iron or magnetic links in the centre, to improve the induction of coil to magnetic line of force.
Light-emitting diode 3 can use separately, also can unite use with electric capacity and whole utmost point diode.Coil 2 is connected into close circuit with light-emitting diode with lead 4.
The car that magnet 1 can be fixed on bicycle is stuck, coil 2 is fixed on the width of cloth bar of bicycle quick, magnet 1 is equated with the distance of coil 2 to axletree, on the track when even the coil 2 of the position of magnet 1 on width of cloth bar made circular movement, and make the transverse distance between coil 2 and the magnet 1 as far as possible little, but can not collide.With lead 4 coil 2 and light-emitting diode 3 are connected into close circuit, light-emitting diode 3 can be fixed on the width of cloth bar or on the rim, make circular movement with the rotation of wheel.
Also magnet 1 can be fixed on the wheel width of cloth bar, use the same distance of axletree, coil 2 is fixed on car stick, with lead 4 coil 2 and light-emitting diode 3 be connected, light-emitting diode 3 can be fixed on places such as handlebar, car fork.
Above-described magnet 1, coil 2, light-emitting diode 3 and lead 4 can adopt a cover, also can be to add strong illumination, adopt two cover or several covers.

When bicycle when riding, wheel rolling, this moment, bicycle whenever circled, width of cloth bar and car fork meets once, coil 2 just moves once at the magnetic field of magnet 1 mouth, according to Faraday's law, coil 2 just produces pulse current, this electric current passes through lumination of light emitting diode. Light emitting diode 3 just can when making driving at night, be identified with the opposite meeting mutually along with the frequency of the coil 2 cutting magnetic lines of force is glittering like this, also can play the decoration effect. The utility model only consumes magnetic energy with the mutual motion when riding between the bicycle parts, does not increase cyclist's physical demands.
Embodiment: stick one of mounting circular ring shape strong magnet at the bicycle car, one of coil about 1000 circles is installed on bike spoke voluntarily, make on the track of position when coil is made circular movement of magnet, to be fixed on the width of cloth bar with chemical capacitor and the light-emitting diode luminary formed of conducting-state voltage about the rectifier diode about 0.3V, 1000 microfarads, link with lead and coil.
When wheel, the magnetic line of force of coil cutting magnet produces electric current, reaches by rectification, electric capacity to light-emitting diode, promptly sends sparkling light.Because luminary is fixed on the width of cloth bar, then the light of Shan Shaning makes the meeting of distant place at night be convenient to identification with the rotation of wheel, also makes bicycle novel beautiful.
