Technical Field

The invention relates to the field of bicycle power generation, in particular to a light clutch type high-power self-powered device on a bicycle.

Background

With the coming of the intelligent era, more and more small-sized intelligent electronic devices appear in the lives of people, such as smart phones, smart watches, Bluetooth players and the like, and the electronic devices have powerful functions, are small and exquisite, are convenient and fast, can enrich the work and leisure time of people, and have wide application prospects.

However, the insufficient cruising ability of these electronic devices is always a main problem limiting the application range, and the current chemical batteries carried by the electronic devices can only maintain the operation state for two to three hours, and cannot meet the requirement of longer use. The appearance of the mobile power supply relieves the problem to a certain extent, but the mobile power supply is generally large in size and weight and inconvenient to carry, and in addition, the electric quantity stored by the mobile power supply cannot meet the requirement of people who ride bicycles for long-distance trekking. Therefore, generating electricity by using the riding process of the bicycle is a feasible solution to the above problems.

At present, the power generation modes in the market by utilizing the riding process of a bicycle are mainly divided into three modes, the first mode is friction type power generation, a common friction wheel connected with a generator is clung to an outer cover of a front wheel of the bicycle, so that electric energy is obtained through friction between the front wheel and the friction wheel when needed, the power generation mode has serious abrasion on the tire, and meanwhile, the working noise is high; the second type is chain type power generation, which mainly generates power by converting partial kinetic energy of a chain into electric energy, but the equipment has serious damage to the chain; the third is middle shaft type power generation, which mainly utilizes the rotation of the middle shaft to generate power, but the equipment has no clutch device, and can bring great resistance to riding in the time when power generation is not needed.

Disclosure of Invention

In order to solve the problems, the invention provides a light clutch type high-power self-powered device on a bicycle, which has small influence on a rider in the riding process, can capture the energy of the bicycle and can freely select whether to clutch or not so as to charge accompanying electronic equipment.

The invention is realized by the following technical scheme:

the utility model provides a bicycle-mounted high-power self-power supply unit of light-duty separation and reunion formula which characterized in that: the bicycle comprises a bicycle frame, a bicycle middle shaft, a large bevel gear, a small bevel gear shaft, a one-way clutch bearing, a motor shaft, a generator, a flywheel, a generating set fixing shaft sleeve, a bridge rectifier and a voltage stabilizer loop. The large bevel gear is fixed on a middle shaft of the bicycle, the small bevel gear meshed with the large bevel gear is fixedly connected with a gear shaft, the gear shaft is connected with a motor shaft through a one-way clutch bearing, so that torque generated when the bicycle is pedaled is converted into rotary motion of the motor shaft, the generator generates electricity, the bridge rectifier and the voltage stabilizing circuit ensure that the generator finally outputs stable voltage required by charging of electronic equipment, meanwhile, a flywheel at the tail end of the motor shaft can increase inertia of the motor shaft, and the fixed shaft sleeve of the generating set can fix the whole generating set on different heights and angles of a bicycle frame, so that meshing and separation among the bevel gears are realized.

The large bevel gear is fixed on the bicycle middle shaft through a spline or welding and rotates synchronously with the middle shaft.

The middle shaft can be designed according to different frame structures, so that the large bevel gear and the small bevel gear have different meshing directions, and the occupied space of the structure is reduced.

The small bevel gear is fixedly connected to one side shaft end of the small bevel gear shaft and meshed with the large bevel gear to change the power direction.

The inner side of the one-way bearing is connected with the small bevel gear shaft, and the outer side of the one-way bearing is connected with the motor shaft, so that the power between the motor shaft and the bevel gear shaft is guaranteed to be cut off when pedaling is not performed.

The generator is fixed on the motor shaft through the generating set fixing shaft sleeve, and the generator generates electricity through the rotation of the motor shaft.

The bridge rectifier and the voltage stabilizing loop ensure that the generator finally outputs the stable voltage required by charging of the electronic equipment.

The flywheel at the tail end of the motor shaft can increase the rotation inertia of the motor shaft, so that the motor shaft can continue to rotate by means of the inertia of the flywheel when the pedaling of the motor shaft is stopped temporarily, and the generator can continue to generate electricity.

The generating set fixing shaft sleeve can adjust and fix the whole generating set to different heights and angles of a bicycle frame, so that meshing and separation among bevel gears are realized.

The invention has the advantages that: 1) simple structure is light, and is less to the influence of riding the in-process to the rider. 2) The bevel gear on the middle shaft of the bicycle drives the generator, so that the efficiency is high and the power is high. 3) The one-way clutch can ensure that the power between the motor shaft and the bicycle middle shaft is cut off when pedaling force is not applied. 4) The generating set can be conveniently installed at different heights and angles of the frame, and meshing and separation between the bevel gears are achieved, so that resistance of the generating set to riding when charging is not needed is greatly reduced.
