Self-generating device of bicycle

Abstract

The invention discloses a self-generating device of a bicycle. The self-generating device of the bicycle comprises a generating box and magnetic field devices. The generating box and the magnetic field devices are of split structures, the magnetic field devices are fixedly installed on spokes of a wheel, the generating box is fixedly installed at the position, corresponding to the magnetic field devices, of an axle, the position, relative to the magnetic field devices, of the generating box on an axle is adjustable, a generating coil, a rectifier used for rectifying the generating coil, and a rechargeable battery used for supplying supplementary power outwards are fixedly installed in the generating box, the power supply output end of the generating box is in electrical connection with a headlight of a bicycle body and a backlight of the bicycle body. According to the invention, the generator magnetic field part is directly installed on the wheel, the generating coil is independently installed on the axle, so that the structure is simplified, the use is more flexible, the part, protruding out of the bicycle body, of the axle is used ingeniously, the generating box is installed simply and rapidly, a transmission part is omitted, magnets are directly fixed onto the spokes of the wheel and move along with the spokes, thus the problem of friction is not caused, the bicycle body is portable, the running resistance of tyres is small, components are not easily worn and torn, and the service life is long.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a bicycle self-generating device. Background technique [0002] When driving at night, in order to facilitate cycling and ensure driving safety, lighting for cycling at night is the biggest problem. More and more bicycles are equipped with lighting devices, especially mountain bikes. If an external power supply is used, not only the structure is complicated, but also the battery needs to be replaced frequently , using mountain bike riding power to power lighting fixtures, not only simplifies the structure, but also saves costs, and has been favored by the majority of users. However, the existing mountain bike self-generating devices all convert the rotation of the wheel into the rotation of the rotor of a small DC generator, and then supply power. Specifically, the generator is an independent overall structure, and the contact between the generator rotor and the wheel is controlled by the...

However, the existing mountain bike self-generating devices all convert the rotation of the wheel into the rotation of the rotor of a small DC generator, and then supply power. Specifically, the generator is an independent overall structure, and the contact between the generator rotor and the wheel is controlled by the rotating bearing Whether to generate electricity, or to generate electricity through friction tires, no matter which of the above self-generation modes, there are many problems such as complex structure, high cost, fast wear of tires and accessories, large riding resistance, heavy car body, and not light.
