Abstract

The invention discloses an electric power generating device applied on a wearable object. The electric power generating device comprises a transmission unit, a magnetic permeable member, a magnetic member, a core, and a coil. The transmission unit transfers an external force received by the wearable object to a driving force. The core is configured in the wearable object and has a first end. The coil is coupled to the core. The magnetic permeable member is configured in the wearable object to receive the driving force and move by the driving force. The magnetic member is configured on the magnetic permeable member and near the first end. When the magnetic permeable member pushes the magnetic member to move relatively to the first end through the driving force, the magnetic flux in the core varies to lead the coil to induce an induced electromotive force.

Dependent claims

An electric power generating device for a wearable object, the electric power generating device comprising:

a transmission unit configured in the wearable object, for transferring an external force received by the wearable object to a driving force;
a core configured in the wearable object, the core having a first end;
a first coil coupled to the core;
a magnetic permeable member configured in the wearable object and connected to the transmission unit, for receiving the driving force and moving relatively to the first end by means of the driving force;
a first magnetic member configured on the magnetic permeable member;
and
an electric power transforming module coupled to the first coil;
wherein when the magnetic permeable member receives the driving force and moves relatively to the first end, the magnetic permeable member pushes the first magnetic member to move relatively to the first end, which results in the magnetic flux varied in the core to induce a first induced electromotive force in the first coil, and the electric power transforming module transforms the first induced electromotive force into an electricity.
