Bicycle power generator for charging mobile phone

Abstract

The invention discloses a bicycle power generator for charging a mobile phone. The bicycle power generator comprises a bicycle main body, wherein a front fork of a bicycle is fixedly connected with a generator stator; a coil installation groove is arranged in a power generation turn plate; a power generation coil is arranged in the coil installation groove; coil connection lines are arranged on the power generation coil; all coil connection lines are connected to a rotating collector ring; a fixed carbon brush ring is arranged in the rotating collector ring; a power line is arranged in the fixed carbon brush ring; the other end of the power line is connected with a center conductor; a permanent magnet installation groove is arranged in the generator stator; a permanent magnet s arranged in the permanent magnet installation groove; the center conductor is connected with a controller at a handlebar; and the middle part of the handlebar is movably connected with a mobile phone support frame. No contact or friction is formed between the power generation turn plate and the generator stator in the power generation process, the power generation resistance is reduced, the power generation efficiency is improved, the damage to the bicycle is reduced, the service life of the power generator is prolonged, output current and voltage are more stable and the damage to mobile electric equipment such as the mobile phone is reduced.

Description

technical field [0001] The invention relates to the technical field of bicycle power generation, in particular to a bicycle power generation device for charging mobile phones. Background technique [0002] In traditional industries, bicycles are loved by residents all over the world for their advantages such as environmental protection, fitness, and convenient transportation. At present, the development of electronic products is advancing by leaps and bounds, and electronic products such as mobile phones and tablet computers have become an indispensable part of people's lives. Electronic products are highly dependent on batteries. If you ride a bicycle outdoors, the batteries of electronic products will run out, which is a very troublesome thing for everyone. Condition. And for the people who go out by bicycle, there will be a lot of motivations that have been wasted in vain in fact. [0003] At present, there are many types of bicycle power generation, roughly including ...

AI Technical Summary

Problems solved by technology

The chain power generation device needs to be closely combined with the bicycle chain. When riding, the friction force is increased to make riding difficult. When the bicycle is coasting, the chain is in a motionless state, and the power generation device does not generate electricity. And when the riding speed reaches a certain speed , the power generation device is easy to slip off from the chain, and the reliability is not high

The friction power generation device has a large friction force, which makes riding hard and easy to wear

[0004] In addition, the output voltage of the power generation device changes according to the speed of the bicycle, and cannot output stably. Using such electricity to charge electronic equipment is easy to damage the electronic product, and when these power generation devices are used on the bicycle, due to Both need friction transmission with the bicycle, which will not only cause damage to the bicycle, but also generate a lot of noise during the riding process, which has a serious impact on the riding experience
