A bicycle power generator has been devised in which the generator is fixed to the flange 23a of the frame 25 with bolts 24, and the inner surface of the base of the frame 25 is pressed to form a recess 25a so that the outer surface of the stator 20 does not come into contact with it.

た。(Problem that the invention aims to solve) By the way, in the above conventional technology, when the rotor is made of synthetic resin, when the natural frequency of the rotor matches the timing of cutting the magnetic lines of force of the multi-pole magnet with the coil, it resonates and generates sound. Also, if there is an external collision such as when the bicycle falls over, the rotor tends to come off the hub flange, and even though it is installed between the frame and spokes of a certain size, the width between the stator and rotor outer surface is somewhat wider than that. However, since the inner surface of the frame must be pressed to form a concave portion, it cannot be directly installed on an off-the-shelf bicycle, and the cost increases due to the effort required to process the frame.

The rotor is characterized in that the inner surface of the rotor is attached along the outer surface of the spokes, and at least a portion thereof is brought into contact with the spokes.

けたコイル１５のターミナルである。 The illustrated embodiment will be described in detail below. 1 is a wheel axle fixed to a frame 2 with a nut 3; 4 is a hub rotatably attached to the wheel axle 1; spokes 6 are fixed to flanges 5 at both ends. 7 is the rotor of the generator and the center boss part 8
into the center hole 10 of the bearing part 9 of the hub 4, fit the horizontal groove 12 of the mounting circular plate 11 into the hub 4 so that it abuts the outer surface of the bearing part 9, and attach the rotor 7 and the mounting circular plate 11 to the hub with bolts 13. 4, the inner surface of the rotor 7 is inclined along the outer surface of the spokes 6, and the rotor 7 is attached so that at least a part thereof comes into contact with the spokes 6. 14 is a stator of a generator, which is fixed to the wheel shaft 1. The coil 15 of the stator 14 is inclined in the same way as the rotor 7, and is arranged opposite to the inner circumferential surface of a multipolar magnet 16 fixed to the outer circumferential inner surface of the rotor 7 with a small gap. It has been set up. 17 is a terminal of the coil 15 attached to the stator 14.

機を取り付けることができる。 Next, the effect will be explained. When the wheel rotates, the rotor 7 rotates together with the spokes 6 and hub 4, and current is generated in the coil 15. Even if the rotor 7 vibrates due to resonance during rotation, the spokes 6 absorb the vibration and do not generate sound. Furthermore, even if an external force is applied to the generator, the spokes 6 absorb that force, so it is difficult to come off, and since the rotor 7 and stator 14 are both inclined along the spokes 6, the space between the frame 2 and the spokes 6 can be used effectively. , the generator can be attached to the ready-made bicycle frame 2 without any modification.

着できるという実用的効果を有するものである。(Effect) According to this invention, the stator is fixed to the wheel shaft,
In a bicycle power generation device in which the rotor is fixed to the hub flange, the inner surface of the rotor is attached along the outer surface of the spokes, and at least a portion of the rotor is in contact with the spokes, so even if the rotor resonates, the spokes will not be affected. It absorbs vibrations so no sound is generated, and even if an external force is applied to the generator, the spokes absorb that force so it does not come off easily.Also, since the generator is placed along the spokes, there is no space between the frame and the spokes. This has practical effects in that it can be used effectively and can be attached to a ready-made bicycle as is.
