Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle tire and a power generation system using its rotational force. 2. Description of the Related Art In conventional power generation, a rotating shaft head of a generator is constantly brought into contact with a side surface of a rotating tire to continuously generate and emit light by its rotational force. [0003] In conventional power generation, the rotary shaft head of the generator is tilted with a strong spring, and the power is continuously generated by rotating the generator in contact with the side surface of the tire. Therefore, there is a problem that a strong leg force for obtaining both stable driving and power generation at all times is required, and the user is very tired. [0004] An object of the present invention is to reduce the blinking lights and leg strength by changing continuous power generation to intermittent power generation. [0005] In order not to generate power continuously, the rotating shaft head of the tilted generator should not be always in contact with the side surface of the tire. [0006] To this end, a rail-shaped trapezoidal raised portion and a flat portion having a generator rotating shaft head width are provided on the side surfaces of the tire, and the rotating shaft head is rotated only in contact with the upper surface of the raised portion.
The flat portion is the same as the conventional tire side surface, and is not changed. Provide a gentle slope to the raised area. In order to prevent the rotating shaft head from coming into contact with the flat portion, the clearance between the rotating shaft head and the tire should be kept at the flat portion.
The generator is adjusted and fixed with the tilt-down flat bracket so that it rotates in contact with the raised portion. [0008] The tilt-down flat metal fitting is covered with a slightly thick rubber or vinyl for the purpose of buffering the sound from the generator body and protecting the sound. [0009] When the tire makes one rotation, contact rotation power is generated at the raised upper surface portion, and no contact occurs at the flat portion, so that intermittent power generation is possible and leg strength is reduced. Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a normal running state, and FIG. 2 shows a night state running state in which the rotating shaft of the generator is tilted to the tilt-preventing flat metal fitting, and rotates in contact with the raised portion on the side of the tire to generate power. Thereafter, the rotated tire becomes a flat portion, and the tire is not in contact with the tire due to the action of the flattened metal fitting of FIG. 3, so that the rotational load is reduced. The periodic rotation of the flat ridge generated intermittent power generation, and reduced leg strength. According to the intermittent power generation operation, the vehicle becomes a flashing light running, and can give attention to the other party. In addition, leg strength can be reduced, and night driving becomes easier. It is believed that the invention reduces dangerous unlit driving.
