Abstract

Provided is a power generation system capable of efficiently converting wind power into electric power. The power generation system comprises: a pneumatic tire; a wheel on which the pneumatic tire is mounted; and at least one generator wind turbine attached, in a cavity defined by the pneumatic tire and the wheel, to the pneumatic tire and/or the wheel.

First claim

1 . A power generation system comprising:
a pneumatic tire; a wheel on which the pneumatic tire is mounted; and at least one generator wind turbine attached to the pneumatic tire and/or the wheel in a cavity defined by the pneumatic tire and the wheel.

2 . The power generation system according to claim 1 , wherein the generator wind turbine is fixed to at least one of the pneumatic tire and the wheel.

3 . The power generation system according to claim 2 , wherein the generator wind turbine is attached to the wheel and can rotate relative to a straight line parallel to an axis of rotation of the tire.

4 . The power generation system according to claim 1 , wherein the generator wind turbine can slide relative to the pneumatic tire or the wheel.

5 . The power generation system according to claim 1 , wherein a dimension of the generator wind turbine in a tire radial direction is no less than 15% and no more than 75% of a cross-sectional height of the tire.

6 . The power generation system according to claim 5 , wherein a dimension of a blade part of the generator wind turbine in the tire radial direction is no less than 75% and no more than 95% of the dimension of the generator wind turbine in the tire radial direction.

7 . The power generation system according to claim 1 , further comprising a rechargeable battery that stores electric power obtained by the generator wind turbine.

8 . The power generation system according to claim 1 , wherein a spoke of the wheel has a hollow region and an electric power line extends from the generator wind turbine to an exterior of the power generation system via the hollow region.

9 . The power generation system according to claim 1 , wherein the electric power line extends from the generator wind turbine to the exterior of the power generation system via a hub of the wheel.

10 . The power generation system according to claim 1 , wherein the generator wind turbine includes a blade part, a cylindrical main body formed in a periphery of the blade part, and a flange formed in one edge portion of the cylindrical main body.

11 . The power generation system according to claim 3 , wherein a dimension of the generator wind turbine in a tire radial direction is no less than 15% and no more than 75% of a cross-sectional height of the tire.

12 . The power generation system according to claim 11 , wherein a dimension of a blade part of the generator wind turbine in the tire radial direction is no less than 75% and no more than 95% of the dimension of the generator wind turbine in the tire radial direction.

13 . The power generation system according to claim 12 , further comprising a rechargeable battery that stores electric power obtained by the generator wind turbine.

14 . The power generation system according to claim 13 , wherein a spoke of the wheel has a hollow region and an electric power line extends from the generator wind turbine to an exterior of the power generation system via the hollow region.

15 . The power generation system according to claim 14 , wherein the electric power line extends from the generator wind turbine to the exterior of the power generation system via a hub of the wheel.

16 . The power generation system according to claim 15 , wherein the generator wind turbine includes a blade part, a cylindrical main body formed in a periphery of the blade part, and a flange formed in one edge portion of the cylindrical main body.
