Description

The generating of bicycle shaft attached and light set composite

Technical field

The utility model relates to dynamo lighting set, relates in particular to a kind of outside that is installed in bicycle shaft, with the generating and the light set composite of conventional tire friction and the diverse bicycle shaft attached of hub-type electrical generator.

Background technology

Along with the global warming and the energy reduce the development of situation day by day, carbon reduction has become the target that the whole world is pursued.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.

Because bicycle belongs to a kind of light-duty vehicle, therefore always relegate to the category of things wanting for the illumination equipment of steam turbine car indispensability.But the ratio of the traffic accident of bicycle generation in recent years day by day improves, and further investigation reveals that, its major cause promptly lacks active illumination and alarming device because of bicycle, causes it easily to be ignored by the steam turbine car in advancing, thus accidents such as generation side swipe.So traffic management system is for improving traffic safety, the regulation bicycle must be forced the active light equipment of installing.

Be used in the active light equipment of bicycle at present, many different modes arranged, illustrate respectively now as the back:

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, by the ON/OFF or the flicker of the controlling switch lamp light on the light-emitting device; But, as utilize the method for battery as electric power source, because of must often changing battery in the use, cost height not only, and do not meet the environmental protection demand; Moreover, as with commercial power charged light-emitting device, be not conveniently in the use, therefore more impracticable.

Another kind method is to utilize cyclery to come in as the propulsion source of generating, and it roughly has two kinds of methods:

First kind of tire triboelectricity (custom is planted dynamo-powered lamp): as shown in Figure 1, it is the front vehicle frame 14 that a small generator 11 is installed in bicycle, with a kind of clutch component 13 electrical generator 11 is separated with tire 15 when not using, when needing light, drive wheel 12 with electrical generator 11 rotating shafts abuts on the tire 15 again, with the gyroscopic movement of this tire 15 and then drive this electrical generator and rotate, make electrical generator 11 produce electric power via the process of magnetoelectricity conversion, supply this car light 16 power supplys according to this.But this kind be with the electrical generator of tire friction, is easy to advantage though have simple in structure, low cost and install, and it still has following shortcoming: 1, efficient is low.Owing to be to use the single phase generator form, the efficient of electrical generator 11 is very low, therefore needs high rotating speed just can make it meet car light 16 and lights required electric power.2, fault rate height.Owing to need high rotation speed operation, so the rotating speed of drive wheel 12 is very high, but this generator 11 is not equipped with corresponding bearing, so fault rate height.3, resistance is big.This electrical generator 11 is to drive via generator drive wheel 12 and tire 15 tyre surface frictions, for guaranteeing generator drive wheel 12 certain and tire 15 tyre surface frictions, therefore can these clutch component 13 design-calculateds are strongr, making tire 15 can drive electrical generator 11 at any time rotates, also therefore generator drive wheel 12 compressings just can convert resistance at the pressure of tire 15 tyre surfaces, make the person of taking advantage of of bicycle experience very big resistance, have uncomfortable feeling.4, electric wire exposes.Therefore direct mount electric light need not have one section electric wire 17 to expose, and to connect car light 16, exposed electric wire 17 might be twisted off or weathering, causes wire short-circuiting or opens circuit.

Second kind of hub-type electrical generator: as shown in Figure 2, this electrical generator 19 directly is combined in this wheel hub 18, its hub shell 181 inner edges are fixed with magnet 191, and outstanding this shell 181 in wheel hub 182 two ends and is fixed on 14 of vehicle frames, executes commentaries on classics and supports this freely and take turns hub shell 181, make the power coil 192 that is located at this wheel shaft 182, when tire 15 rotates and interlock should wheel hub shell 181 time, the relative motion of magnet 191 and power coil 192 promptly forms the generating effect.But, this kind hub-type electrical generator, though advantage such as it is low to have a resistance, and structure-integrated and fault is low, it still has following disappearance: 1, install and be difficult for.Because it is installed on the wheel hub, therefore the wheel hub that the size of this a wheel hub is more general is big, only when the assembling new car, just it is designed in wheel, and be to want to install this kind of electrical generator else if afterwards, whole wheel need be changed, be not easy very much installing also.2, efficient is low.This electrical generator uses the axle center generating, so its rotating speed is identical with the vehicle wheel rotational speed of bicycle, and relative rotating speed is much lower than dynamo-powered lamp, so the efficient step-down, and in order to reach the power supply output identical with dynamo-powered lamp, therefore needs bigger generator designs.3, can't separate.When not needing generator for electricity generation, electrical generator can't separate with wheel, though the resistance of electrical generator is low under non-loaded situation, but because this kind of electrical generator needs high efficient, to deal with the demand of the high output of slow speed of revolution, therefore all design-calculated is very little the gap between magnetite and the stator, even certain resistance is also arranged when not generating electricity, causes rider's burden.4, cost height.For above-mentioned reasons, so the design of electrical generator is bigger, therefore need higher cost.5, electric wire exposes.Can't the direct mount electric light, therefore need there be one section electric wire to expose, to connect electric light, the electric wire that exposes might be twisted off or weathering, causes wire short-circuiting or opens circuit.So existing two kinds of bicycle generation modes still have it not improve part to the greatest extent, and room for improvement is still arranged.
