Description

Bicycle power generator

A bicycle power generating device, in particular, a power generating device that generates electric power by vibration of a rider during riding, which further supplies power required for a related electronic product on a bicycle that needs to be applied to electric power, It is an invention with excellent practicality.

With the positive effects of bicycles, many people are gradually investing in this healthy life movement. However, in this healthy exercise, there must be sound preparations, such as providing safe riding lights. Brake lights, or sensing devices used to detect the rider's heart rhythm, breathing, etc., in addition to more related peripheral products for the rider to use, these supplies are more suitable to provide the rider It has good protection in sports and avoids dangerous situations. Therefore, the relevant manufacturers in the bicycle peripheral products spare no effort in the research and development of related products.

Looking at these related peripherals, most of them need to use the power drive to operate. However, the common peripheral products on the market are driven by a variety of batteries, but with environmental awareness. Head-ups, such products as batteries contain heavy metals such as mercury and nickel, which easily affect the environmental pollution caused by the disposal of batteries, which in turn affects the lives of animals, plants and humans. Therefore, products such as batteries are gradually being replaced. And the progress of the times has gradually solved the problem of the previous battery. Serious problems that have arisen since then, the relevant industry now applies the idea of power storage to the peripheral products of bicycles, and supplies related products through electronic transmission, such as USB and mains connection, to store power in bicycle-related products. The user's application during riding, but the general storage capacity is limited. When the rider forgets to charge it, the internal power supply cannot be used, and the rider has a plug-in power supply when they are exercising outside. Looking for, the related products are not available, thereby increasing the risk of the rider.

In addition, when the rider is riding, if the lighting used for lighting or the rear brake light used to warn the rear visitors does not have stored electricity, it is easy for the rider to Clearly identify the road conditions and cause dangers such as falling, collision, or the rear personnel to clearly identify the location of the rider, and effectively know whether the rider is ready to brake, turn left or turn right, etc. It will cause the chasing of the rear personnel, which will not only harm others but also increase their own danger. Therefore, no matter whether the provision of the above-mentioned power source causes any inconvenience to the rider, the safety of riding is also required to be greatly improved. Therefore, the relevant industry must further think about how to provide the rider with the appropriate amount of electricity for use in related products.

In view of the above situation, the inventors invested a lot of time to research relevant knowledge, and compared various advantages and disadvantages, carried out research and development of related products, and conducted numerous experiments and tests, and finally introduced a "bike power generation device" improvement. The above missing is in line with the needs of the public.

The main object of the present invention is to provide the electric power that the rider can convert into the peripheral products of the bicycle through the vibration power that the rider has when riding, and the improvement of the early power supply can be operated through the installation of the battery, but the battery causes Environmental pollution and loss of weight during riding are missing.

To this end, the present inventors have made great efforts to achieve the object and effect of the foregoing invention. A bicycle power generating device is provided in a bicycle seat cushion and provides power supply, and includes a piezoelectric power generating sheet and an electric power output manifold: the pressure The electric power generating piece is electrically connected to the power output bus, and the piezoelectric power generating piece senses the upper and lower clips generated by the bicycle seat cushion during riding, and the spontaneous power is supplied to the external power supply through the power output confluence; wherein The piezoelectric power generation piece of the bicycle power generator generates electric power by the rider's up and down vibration generated by the seat during riding, and supplies the electric power to the peripheral products on the bicycle via the power output bus.

A further technical feature of the present invention is that the shaft pocket of the upper clip can be a shaft recess, and the shaft protrusion corresponding to the lower clip is a corresponding shaft bump.

A further technical feature of the present invention is that the shaft pocket and the shaft projection can be disposed on the end sides of the upper clip and the lower clip.

Combining the features described above with respect to the present invention, the advantage is that the rider only needs to ride the bicycle seat cushion and further provide the piezoelectricity in the bicycle power generating device by the up and down vibration power generated by the riding process. The power required for the power generating sheet, when the piezoelectric power generating sheet is operated by vibration, generates electric power due to the setting of the internal material characteristics, and further transmits the generated electric power to the peripheral related electric products on the bicycle via the power output confluence. Significantly reduce the use of the battery to affect the environment, and can avoid the lack of power on the way to the door. Therefore this The invention can be said to be a quite practical and progressive invention, which is quite worthy of promotion by the industry and publicized to the public.
