Abstract

The invention provides a bicycle power generation device with an automatic clutch, which comprises a direct current generator, and further comprises a centrifugal clutch, wherein the centrifugal clutch is mounted on the rear axle of a bicycle through a one-way bearing; and the direct current generator and the centrifugal clutch are connected with each other in a mechanical driving manner. The resistance generated by the power generation device can be offset due to the inertial force of the rotating wheels by adjusting the combined rotational speed of the centrifugal clutch, so that a rider cannot feel tired while riding the bicycle; the mounting and the maintenance are relatively simple; and a storage battery is contained, so as to ensure stable output current and further avoid abrasion on the tires of the bicycle.

Example Embodiment

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.
[0016] like figure 1 , figure 2 As shown, it includes a DC generator 3, a centrifugal clutch 2, the centrifugal clutch 2 is installed on the rear wheel axle 11 of the bicycle through a one-way bearing, the DC generator 3 is installed on the rear fork of the bicycle through a bracket 4, and the DC generator 3 and the centrifugal clutch 2 pass through Mechanical transmission connection. When the bicycle is riding, the sprocket 12 drives the rear wheel 1 and the rear axle 11 to rotate. At this time, the DC generator 3 does not work. When the rear axle 11 reaches a certain speed, the centrifugal clutch 2 is combined and drives the DC generator to generate electricity through mechanical transmission. Since the centrifugal clutch 2 is combined to drive the DC generator 3 to work when the rear wheel shaft 11 reaches a certain speed, the user will not feel the resistance brought by the operation of the DC generator 3 during slow-speed driving such as starting the bicycle or going uphill. . When the rear axle 11 reaches a certain speed, the bicycle already has a certain speed, and the rotation of the rear axle 11 also has a certain inertial force. At this time, the centrifugal clutch 2 is combined to drive the DC generator 3 to work, and the resistance generated by the DC generator 3 The inertial force of the rear axle 11 is opposite to each other, so they can cancel each other out, so that the user does not feel or only feels a very slight resistance. By adjusting the combined speed of the centrifugal clutch 2, the magnitude of the inertial force generated by the rear wheel shaft 11 when the DC generator is working 3 can be adjusted, and the best matching state of the two has been achieved. It is also possible to install DC generators with different resistances on the bicycle in this way. Adjustment.
[0017] Gears, chains or belts can be used for the transmission of the equipment between the centrifugal clutch 2 and the DC generator 3 . Gear transmission can withstand large forces and high rotational speeds. The chain drive can flexibly adapt to the positional distance between the centrifugal clutch 2 and the DC generator 3 . Belt drives reduce manufacturing costs and overcome chain stretch issues. The mounting bracket 4 can adjust the distance and position between the DC generator 3 and the centrifugal clutch 2, and can flexibly adapt to different transmission ratios.
[0018] Centrifugal clutch 2 can choose radial spring brake block centrifugal clutch, free brake block centrifugal clutch or roller centrifugal clutch. The radial spring brake block centrifugal clutch has good stability after being combined, which can make the DC generator 3 work smoothly. The free brake block type centrifugal clutch can make the prime mover start near no-load, which improves the riding comfort of the bicycle. The roller centrifugal clutch can adapt to frequent separation and coupling, and is suitable for harsh working environments, and is suitable for riding at critical speeds for a long time.
[0019] like image 3 As shown, the present invention also includes a storage battery 5, and a DC power lighting component 7, the storage battery 5 is connected with the DC generator 3 through a cable, the DC lighting component 7 is connected with the storage battery 5 through a cable, and the DC power lighting component 7 is connected with the storage battery 5. A switch 6 is also connected in series, the DC generator 3 charges the storage battery 5 , and the storage battery 5 provides power for the DC power light-emitting component 7 . The existing bicycle power generation system generally directly connects the generator with the lighting equipment. Since the electricity generated by the generator is directly related to the driving speed of the bicycle, and the bicycle is generally unlikely to travel at a constant speed for a long time, this method will make the lighting The device does not work erratically. In the present invention, the use of the storage battery 5 to provide power to the DC power light-emitting component 7 can make the DC power light-emitting component 7 work smoothly. Light-emitting diodes have low power consumption and long service life.
