The retaining bearing 5 is @ disposed on the inner side of the small aperture section of the body unit 2 surrounding the wall 22, and is coupled to the axis of rotation of the rotor unit 4 to be in the chaotic system of the shaft tube 23 + λ ^ The inner bearing 24 cooperatively supports the revolving shaft 41. In the embodiment, the retaining bearing 5 is an oil-impregnated bearing, so that the full lubricating fluid contacts the rotating shaft 41 to keep the rotating shaft 41 rotating. The smoothness of the time, but also the roll point & + # is a bead bearing or other type of bearing, and should not be limited to the aspect disclosed in this embodiment. The auxiliary bearing 6 is disposed on the inner side of the crucible and is in contact with the bottom of the shaft tube 23 of the pumping shaft, and further supports the bottom of the rotating shaft 41. In the embodiment, the auxiliary bearing 6 is Push the bearing. - It is disposed at the bottom of the shaft tube 23 of the body unit 2, and is sealed at the bottom of the shaft 23 to prevent the muddy oil for assisting the rotation of the shaft (1) from leaking from the bottom of the shaft tube 23. The rotating shaft M355881 π / 』 cover 7 is disposed on the outer side of the body _ 22 of the body _ 22 :: 2 on the outer side 'and laterally surrounding the contact member 43 , the contact member 43 in the wheel 1 When it is rotated by contact with friction, it will not be disturbed and affect its rotation, so that the power generation module can be more stable. In addition, the power generation module L of the bicycle power generation device is used in rainy days. The wheel _ is exposed to rain or mud after the contact, and the contact member 43 will pull out the rain (mud) water when it is rotated, and the protective cover 7 can effectively block the contact member 43. Rain (mud) water, ^ it will not affect the rider of the bicycle or the surrounding environment. When the bicycle is in the running day, the contact member 43 is in contact with the wheel 100 of the bicycle, and by the friction between the two, the wheel (10) is rotated to drive the rotation of the vertical contact member 43 to drive the shaft. 41 rotates about its own axis, and the connecting member 44 sleeved on the rotating shaft 41 also rotates 'and drives the magnet ring 42 and the patches of the stator unit 3 to produce mutual electromagnetic compatibility. The interaction 'in turn generates a potential in the coil 33 and produces a current run, thereby converting mechanical kinetic energy into electrical energy for use by external electronic devices (such as lights, not shown). The advantage of the present invention is that the retaining bearing 5 disposed on the inner side of the small aperture & 222 of the surrounding wall 22 and the auxiliary bearing 6' disposed on the inner side of the bottom of the body unit 2 are fitted to the shaft. The bearing Μ in the pipe Μ enables the upper shaft, the middle shaft and the lower portion to be supported and supported in the upper, middle and lower sections, so that no yaw is generated, so that the shaft 41 can be rotated more smoothly. It can improve the power generation efficiency of the conventional power generation module due to the yaw of the rotating shaft, and the structure of the rotating shaft 131 is easily deformed. 10 M355881 ' In addition, since the retaining bearing 5 can further prevent rainwater or water, gas permeates from the small aperture section 222 to prevent rain or water from causing a short circuit to the coil 33 located in the large aperture section 221, It helps to improve the overall operational safety of the device, and the auxiliary bearing 6 also has the effect of preventing the lubricating oil for assisting the rotating shaft 41 from leaking out from the bottom of the shaft f 23. The preferred embodiment of the power generating module of the bicycle power generating device is substantially the same as the first preferred embodiment, and the same is no longer in common. 'The difference is that: this embodiment uses two groups. The stator unit 3 is disposed on the shaft tube 23 and located in the large aperture section 221, and the rotor unit 4 has two complex pole faces 311 disposed on the connecting member 44 and surrounding the corresponding silicon steel sheets 31. The magnet ring 42 causes the magnet rings 42 to respectively generate electricity for the stator unit 3, and thus the embodiment is formed to have a double-layer generator to produce a larger power output. _ The above-mentioned power generation module of the bicycle power generating device of the present invention uses the holding bearing 5 and the auxiliary bearing 6 to additionally support the rotating shaft 41, and has the functions of preventing rainwater infiltration and preventing lubrication oil. The advantage of the leak is that it can achieve the advantages of high safety and practicability while ensuring the rotation axis of the shaft W and thus making it non-deflecting, so that the purpose of the present invention can be achieved. The above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the present invention to the extent that it is simple equivalent change and modification according to the scope of the novel application and the novel description. , M355881 is still covered by this new patent.
