Description

  The present invention relates to a bicycle power generator and a coaxial localization cover. Specifically, it is a power generator specially designed for bicycles. Unlike general hub dynamo type generators, manufacturers can speed up production and installation. According to the design of the cover, the user relates to a bicycle power generator and a coaxial localization cover that can be installed by the user.

  In recent years, as cycling by bicycle has become widespread as an exercise, safety, entertainment, and convenience of riding a bicycle have become important. For example, add a main warning light emitting device and lighting equipment on the bicycle body to improve riding safety, or use a portable electronic product to record the bicycle travel, speed, position, etc. However, there are users who want to increase the fun of cycling. However, whether it is a light-emitting facility, a lighting facility, or a portable electronic product, there is a problem that power is consumed when the device is used.

  It is clear that replacing green generators with batteries will become a future trend as the idea of green energy spreads. On the other hand, conventional power generation facilities operated on bicycles are roughly divided into an external type and a built-in type.

  The external power generator is a friction generator, and a friction wheel is installed outside the wheel frame of the wheel. Power is collected by friction between the friction wheel and the wheel / wheel frame, and power generation is performed in conjunction with the power generation unit. This type of external power generator has the advantage that it can be easily installed on a general bicycle without changing the design of the bicycle. However, in the friction between the friction wheel and the wheel frame, if the installation is not appropriate, the contact efficiency is deteriorated, and if the torque is excessively applied to the axle at the friction position, resistance is generated during running, and one side of the wheel frame is worn away. There are problems such as being easily deformed and damaged.

  The design of the built-in generator is generally called a hub dynamo generator. This is a set of power generation units embedded in the hub when the bicycle manufacturer manufactures the wheel, and drives the power generation unit when the hub rotates according to the wheel. The power generation efficiency of this type of built-in power generator is somewhat higher than that of an external power generator. However, with the built-in power generation device, the wheel width becomes wide, so it is necessary to specially manufacture the wheel frame of the wheel, and it is also necessary to modify the vehicle body according to the width of the wheel. There is also a problem that the user cannot purchase and replace a commercially available tire wheel. The present invention has been made in view of the above-described drawbacks of conventional bicycle power generators.

  The problem to be solved by the present invention is that the power generation near the center position of the wheel is the main shaft of the design, the power generation performance is provided, and the bicycle power generator and the coaxial localization that the user can attach to a commercially available bicycle by themselves Is to provide a cover.
