Chain-driven double-flywheel interlocking external alternating current self-generating device of bicycle

Abstract

The invention relates to a chain-driven double-flywheel interlocking external alternating current self-generating device of a bicycle, and belongs to the technical field of auxiliary devices of bicycles. The device comprises a forward flywheel and a reverse flywheel, wherein a transmission shaft of the forward flywheel and the reverse flywheel is connected with two alternating current generators by speed governing mechanisms; the two alternating current generators are connected by a bracket I; and a loose edge of a bicycle chain is engaged with the forward flywheel and the reverse flywheel in an "S" shape. The device serves as an external generating system, the whole product is an independent unit, and a bracket of the unit is mounted on a horizontal support bar of a rear wheel of the bicycle, so that mounting and use of the bicycle in any type are convenient.

Description

technical field [0001] The invention relates to a chain-driven double flywheel linkage external AC bicycle self-generating device, which belongs to the technical field of bicycle auxiliary devices. Background technique [0002] The "2010 National Physical Fitness Monitoring Bulletin" and "2013 Survey Results of Physical Fitness Activities and Physical Conditions of People Aged 20-69" released by the General Administration of Sport of China believe that there is a downward trend in the physical function and quality of Chinese people. The country has issued corresponding policy guidance, "The Opinions of the Central Committee of the Communist Party of China and the State Council on Strengthening Youth Sports and Strengthening Youth Physical Fitness" and "Notice of the General Office of the State Council Forwarding Some Opinions of the Ministry of Education and Other Departments on Further Strengthening School Sports Work". To this end, the Ministry of Education comprehensivel...

AI Technical Summary

Problems solved by technology

[0010] 1. The power generation is unstable due to the speed of the vehicle, and there is no rectification and voltage stabilization design, which affects the use and life of electronic products;

[0011] 2. There is no power storage function, and the lights flicker obviously;

[0012] 3. Generator rotors and bearings are prone to wear and tear, and tire wear is large;

[0013] 4. The friction contact surface is easy to slip, which affects the stability of power generation;

[0014] 5. It is necessary to use tools to fix and adjust the contact strength, and professional debugging is required

[0017] 1. The product can only be used with clip-on brakes, and the internal variable car cannot be installed;

[0018] 2. The entire set of wheels needs to be replaced, and a professional car dealer needs to be refitted and debugged;

[0019] 3. The power generation status is unstable, affected by the speed of the vehicle, it will be large and small, which will affect the use and life of electronic products;

[0020] 4. Direct power generation, affecting pedaling force (extra braking function);

[0021] 5. High price;

[0022] 6. Without the power storage function, the lights flicker obviously.

[0024] 1. Refitting requires professional car dealers to refit and adjust, and ordinary bicycles are difficult to refit by themselves;

[0025] 2. The power generation status is unstable, affected by the speed of the vehicle, it will be large and small, which will affect the use and life of electronic products;

[0026] 3. Without power storage function, the lights flicker obviously;

[0027] 4. The power generation is small and the price is high

The price of the hub for axle power generation is too high, generally 200-3000 yuan; the friction method has low power generation efficiency and low power
