Improved structure of bicycle power assist system

This creation is a kind of bicycle power assisting device, especially charged by solar panel illumination and household power rectification, and is adjusted to the appropriate speed with the variable resistance of the sensing control circuit and the power controller. To achieve the power-assisted purpose of bicycle safety.

Air pollution is something that the public can't accept and be angry with, and the main cause of air pollution is nothing more than the large amount of exhaust gas emitted by vehicles. Therefore, in order to solve the problem of increasingly serious air pollution, the future will be non-polluting. The demand for transportation is bound to become more and more ardent. The vehicles that currently meet the most environmental protection requirements should be bicycles and electric vehicles.

Among them, bicycles that rely on manpower to step on are most common. In terms of flat and downhill roads, the bicycle can be advanced by man pedaling, but in the case of climbing sections or special road conditions, the shifting mechanism provided by the bicycle itself can be used. In addition to the purpose of saving effort, if the bicycle is equipped with a power assist system, the power assist system can be activated to assist the user and automatically advance the bicycle without human foot.

However, a large proportion of the power assist system of the conventional bicycle employs a power assisted motor in the center of the frame, and the power assisted motor uses an umbrella gear system to drive the axle of the front toothed disc of the bicycle, and reuses the front. The chain drive drive chain drives the rear chainring to make the bicycle front Progress. Although these institutions can achieve the purpose of providing bicycle auxiliary power, due to the complexity of the mechanism, not only the weight of the bicycle is greatly increased, but also the bicycle and its related connection must be redesigned. In addition, the power supply can only use household electricity. Since charging is implemented, it is not only limited in use, but also cannot be charged while driving, resulting in a short stroke of the effective stroke and cannot be used as an auxiliary for long-distance power.

In addition, as shown in FIGS. 1 to 3, the power supply charging structure of the conventional bicycle assisted power system is such that the household power source (e) is rectified by the rectifier (f) into a DC power source and charged to the battery (g), and the battery is replaced by the battery (g). g) a power supply sensing structure (h) road condition sensing structure (h1), a brake sensing structure (h2), and a speed sensing structure (h3), when the road condition sensing structure (h1) senses the road terrain as an uphill road When the brake sensing structure (h2) senses the no-stop brake signal and the speed sensing structure (h3) does not sense the overspeed, the power controller (i) causes the battery (g) to continue to supply power to the electric motor. (j), let the electric motor (j) continue to operate to output power, and achieve the purpose of power assisted driving.

If the road condition sensing structure (h1) senses that the road terrain is a downhill road condition, the braking sensing structure (h2) senses that the braking signal is to be stopped, and the speed sensing structure (h3) senses the overspeed, the power controller (i) prompts the battery (g) to stop supplying power to the electric motor (j), causing the electric motor (j) to stop rotating, so as to achieve the purpose of timely power-off and braking.

The battery (g) and the speed sensor (h3) are connected to an indicator (m), and the indicator (m) displays the data of the battery (g) and the speed sensor (h3) for the convenience of the user. View.

However, now that energy is gradually depleted, energy conservation and carbon reduction are needed. No green energy structure is used to create power. Only the household power supply power assist system is used, which is less effective in energy saving and carbon reduction and cannot be used for long-distance power assistance.

In view of this, the creators of this case are concerned with the various types of bicycle power assisted systems mentioned above, and based on their experience in manufacturing, to provide "a bicycle power assist system improved structure, through the rectification of household power supply and The solar panel supplies power to the rechargeable battery for the purpose of creating a green power supply.

Another purpose of the creation is to charge and supply power to the battery by charging the battery, so that the rechargeable battery and the power supply battery are separately charged and supplied, and when the charging and power supply are stopped, the rechargeable battery can supplement the power supply to the power supply battery for Long-distance driving and avoiding the purpose of reducing battery life.

The job is to create a power supply controller with variable resistance to control the power supply of the battery. It can be used to adjust the starting speed of uphill and upwind, instantaneous power off of the vehicle, deceleration of overspeed, and illumination. The brightness, the brightness of the warning light, and the brightness of the directional light.
