産業上の利用分野
この発明は、夜間自転車のライトを点燈するための発電
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a power generating device for lighting a bicycle light at night.
従 来 の 技 術
タイヤと発電器の回転部を接触させ発電する従来の発電
装置は、点燈する際自転車の推進と発電を同時に行うの
で、ペダルを回転させるために要する力は、かなりなも
のである。特に雨降り等は、タイヤと発電器の回転部と
の間に、水による摩擦抵抗が増大し、相当の労力を要し
た。Conventional technology Conventional power generation devices generate electricity by bringing tires into contact with the rotating parts of the generator. When turning on the lights, the bicycle is propelled and the electricity is generated at the same time, so the force required to rotate the pedals is considerable. It is. Particularly when it rains, the frictional resistance due to water increases between the tires and the rotating parts of the generator, requiring considerable effort.

イトに接続する。An iron core ('7) with a coil (9) wound around it is fixed to the working axle (1), and on the other hand, N-pole and S-pole magnets ('7) are attached to the inner circumference of the hub (4).
6), alternately fix an even number at equal intervals, and then tighten this knob (4).
Pass the axle (1) through it and fix the center of the rotating part to the axle (1) with a bearing (5). One end of the coil (9) wound around the iron core (7) is grounded, and the other end is connected to the light through the axle (1).

強さ、コイルの巻線回数等変えることにより、起電力を
変えることができる。Here, the conventional electromotive force is rated at 6■, 3W, so it is sufficient to obtain an electromotive force according to this, so the electromotive force E is given by the formula E=1・Pn, G (V) By winding the slot of the iron piece to wind the coil into one piece of iron (the number of turns of the coil is 25 turns, the magnet can be magnetized or demagnetized as desired, so Φ = 0.008 [Wb
) Assuming that the number of magnets in the hub is 14, if the fill winding method is wave winding, a = 2, and the number of revolutions per minute of the bicycle under normal conditions is around 18 to 20 revolutions. Therefore, by applying this to the above equation, we get: The electromotive force can be changed by changing the strength of the magnet, the number of turns of the coil, etc.
以上のことにより通常の状態でライトを点燈することが
でき、従来のように雨降りにライトを点燈すると重くな
るのでライトを点燈しないという不都合なことがない。As a result of the above, the light can be turned on under normal conditions, and there is no inconvenience of not turning on the light because it becomes heavy when the light is turned on in the rain as in the conventional case.
