POWER GENERATOR, POWER GENERATOR SET AND POWER GENERATION SYSTEM

摘要

A power generator 100 includes a power generating unit 10 and a supporting member 20 for supporting the power generating unit 10. The power generating unit 10 constitutes a two-degree-freedom vibration system including a first vibration system having a coil assembly 40 and a first spring portion 64 for coupling the coil assembly 40 with a housing 20 and a second vibration system having a magnet assembly 30 and a second spring portion 65 for coupling the magnet assembly 30 with the coil assembly 40. The power generating unit 10 is configured so that each of a first natural frequency ω1 of the first vibration system and a second natural frequency ω2 of the second vibration system is in the range of 14 to 42 Hz.

主权项

1. A power generator to be used in a state that the power generator is fixedly attached to an air-conditioning duct, the power generator comprising:
a power generating unit for generating electric power by utilizing vibration of the air-conditioning duct; and a supporting member for supporting the power generating unit, wherein the power generating unit constitutes a two-degree-freedom vibration system including a first vibration system having a first mass portion and a first spring portion for coupling the first mass portion with the supporting member and a second vibration system having a second mass portion and a second spring portion for coupling the second mass portion with the first mass portion, wherein a second mass m2 [kg] of the second mass portion is smaller than a first mass m1 [kg] of the first mass portion, and wherein the power generating unit is configured so that each of a first natural frequency ω1 of the first vibration system and a second natural frequency ω2 of the second vibration system is in the range of 14 to 42 Hz by adjusting the first mass m1 [kg] of the first mass portion, a first spring constant k1 [N/m] of the first spring portion, the second mass m2 [kg] of the second mass portion and a second spring constant k2 [N/m] of the second spring portion.
