Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0017] The invention provides a bicycle self-generating device based on Faraday's law of electromagnetic induction. The device has a simple structure and can be directly fixed on an air nozzle to generate electricity.

[0018] like figure 1 As shown, when the magnetic flux in the n-turn coil 1 changes periodically, a periodically changing AC electromotive force will be generated on the n-turn coil 1 . The electromotive force is limited within a certain range through the clamping circuit 2, so as to avoid damage to the electronic components behind due to the excessive amplitude of the electromotive force. After passing through the clamping circuit, the electromotive force is still an AC electromotive force and cannot be directly used in electronic products. The AC electromotive force after the clamping circuit passes through the full-wave rectif...

Abstract

The invention provides a bicycle self-generating device based on Faraday law of electromagnetic induction. The device includes a magnet arranged on a bicycle front-wheel air nozzle and a canvas bag mounted on the bicycle front fork, a fixedly packaged generating device and an interlayer for receiving an electronic product to be charged are arranged in the canvas bag. When a bicycle moves, the magnet rotating along the wheel periodically changes the magnetic flux of the closed coil in a circuit structure to generate the induction electromotive force in cyclic variation, and the AC induction electromotive force is converted into a DC electromotive force being constant in the electromotive direction and stable in magnitude via the circuit structure to charge the electronic product. The device has the advantages of simple structure, low cost, and convenient detachment and carrying, and after the installation, the beauty of the bicycle is not influenced, and the popularization is facilitated.

Description

technical field [0001] The invention relates to the field of bicycle supporting equipment, in particular to a bicycle self-generating device based on Faraday's law of electromagnetic induction. Background technique [0002] At present, the era in which people live is an information age, and various electronic products, such as mobile phones, cannot be separated from improving the quality of life. But continued use of electronic devices depends on providing sufficient power to the electronic devices. However, people often only remember to charge their electronic products when they run out of power, which is very inconvenient for people who are away from home. [0003] At present, the mobile power banks for electronic devices on the market need to be charged in advance, and the more power that can be provided, the longer the charging time is required, and the power that the mobile power can provide at one time is also limited. When people go out and encounter emergency situa...
