Mounting method of electromagnetic generator and tire with built-in electromagnetic generator |
摘要 |
When an electromagnetic generator 10 having a pendulum structure is mounted on an interior surface of a tire 20, an equivalent pendulum length l of a pendulum 14 is adjusted such that an integral multiple of a period λ of the pendulum 14, which is determined by the equivalent pendulum length l of the electromagnetic generator 10, is not in agreement with both of an integral multiple of a circumferential length L of the tire 20 and a length S of a non-grounded part of the tire, which is obtained by subtracting a ground contact length C from the circumferential length L of the tire 20, whereby the power generation capacity of the electromagnetic generator mounted on the tire can be improved regardless of the type of the tire. |

1. A mounting method of an electromagnetic generator having a pendulum structure on an inner surface of a tire, the method comprising:
adjusting an equivalent pendulum length of the electromagnetic generator such that an integral multiple of a natural wavelength λ of a pendulum determined by the equivalent pendulum length is not in agreement with both of an integral multiple of a circumferential length of the tire and a length of non-grounded part of the tire, which is obtained by subtracting a ground contact length from the circumferential length of the tire, and mounting the electromagnetic generator with the adjusted equivalent pendulum length on the inner surface of the tire. |
