Title:
POWER GENERATION MODULE
Document Type and Number:
WIPO Patent Application WO/2022/244088
Kind Code:
A1
Abstract:
This power generation module comprises: a power generation element part that has a magnetic core elongated in one direction, and a coil wound around the magnetic core; an induction yoke part that has a first induction yoke in contact with one longitudinal end portion of the magnetic core and constituted from a magnetic body, and a second induction yoke in contact with the other longitudinal end portion of the magnetic core and constituted from a magnetic body; and a magnet part that can be displaced relative to the power generation element part in a direction orthogonal to said longitudinal direction, and has a first magnet and a second magnet in the displacement direction. The first magnet has an N-pole section and an S-pole section in the longitudinal direction. The second magnet has an S-pole section and an N-pole section in the longitudinal direction. In the displacement direction, the N-pole section of the first magnet and the S-pole section of the second magnet face each other, and the S-pole section of the first magnet and the N-pole section of the second magnet face each other. When the magnet part is at a first position with respect to the power generation element part, the N-pole section of the first magnet faces the first induction yoke, and the S-pole section of the first magnet faces the second induction yoke. When the magnet part is at a second position with respect to the power generation element part, the S-pole section of the second magnet faces the first induction yoke, and the N-pole section of the second magnet faces the second induction yoke.
