Abstract

Provided is a power generation system. 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 to the pneumatic tire and/or the wheel in a cavity defined by the pneumatic tire and the wheel. The generator wind turbine is configured to lay flat or stand upright.

Claims (37)

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,

wherein the generator wind turbine is configured to lay flat or stand upright, and

wherein the generator wind turbine is configured to lay flat when there is no centrifugal force acting on the pneumatic tire and is configured to stand upright when there is a centrifugal force acting on the pneumatic tire.

2. 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.

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

4. 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.

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

6. 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.

7. The power generation system according to claim 1 , wherein the generator wind turbine is slidable relative to the pneumatic tire or the wheel.

8. The power generation system according to claim 7 , 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.

9. The power generation system according to claim 8 , 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.

10. The power generation system according to claim 9 , further comprising a rechargeable battery that stores electric power obtained by the generator wind turbine.

11. The power generation system according to claim 10 , 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.

12. The power generation system according to claim 11 , 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.

13. The power generation system according to claim 12 , 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.

14. 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,

wherein the generator wind turbine is configured to lay flat or stand upright, and

wherein the generator wind turbine is attached to the wheel and is rotatable relative to a straight line parallel to an axis of rotation of the tire.

15. The power generation system according to claim 14 , wherein a dimension of a blade part of the generator wind turbine in a tire radial direction is no less than 75% and no more than 95% of a dimension of the generator wind turbine in the tire radial direction.

16. 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,

wherein the generator wind turbine is configured to lay flat or stand upright, and

wherein the generator wind turbine is slidable relative to the pneumatic tire or the wheel.

17. The power generation system according to claim 16 , 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.

18. The power generation system according to claim 17 , 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.

19. The power generation system according to claim 18 , further comprising a rechargeable battery that stores electric power obtained by the generator wind turbine.

20. The power generation system according to claim 19 , 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.

21. The power generation system according to claim 20 , 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.

22. The power generation system according to claim 21 , 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.
