Problems solved by technology

[0006] This prior art has several disadvantages. The generator coil and magnet of the hub generator for bicycles cannot be easily attached to the bicycle wheel, and the user cannot install the generator without substantially changing the design of the existing wheel. Therefore, we are committed to Researching a bicycle power generation device that can be easily attached to one side of the bicycle wheel, and can make the generator not generate power when power generation is not needed

Abstract

The invention relates to an electricity generating device for a bicycle. The device comprises a driving mechanism, a generator and a transmission piece, wherein the driving mechanism comprises a driving wheel and a clamping device; the clamping device is provided with a plurality of grooves; the grooves are hooked to bicycle spokes; the driving wheel and a bicycle axle share the same circle center; the peripheral surface of the driving wheel is provided with a driving part; the generator comprises a driven wheel; the peripheral surface of the driven wheel is provided with a linked part; the linked part of the driven wheel is driven to rotate by the driving part of the driving wheel; the driven wheel drives the generator to generate electricity; a bicycle wheel drives the driving wheel to rotate; the driving part of the driving wheel drives the driven part of the driven wheel to rotate; and the driven wheel drives the generator to generate the electricity.

Description

technical field [0001] The invention relates to a bicycle power generating device, in particular to a bicycle power generating device attached to a bicycle wheel. Background technique [0002] There are many battery-driven products on the market today that are based on safety or practicality and are widely used by cyclists, such as: front and rear lights (with or without direction lights), MP3 speakers / audio. Even rechargeable thermal jackets, scarves, lunch boxes, insulated coffee mugs, and more. The concern with using these products is the battery's power storage capacity and the need for multiple backup batteries when using multiple products at the same time. A generator for bicycles that is easy to install and can generate sufficient electric energy is necessary. [0003] The most widely used bicycle dynamo for decades is a mechanism that uses friction to rotate the extended shaft of the motor rotor against the side of the tire. This type of design has low efficiency,...
