Abstract

A self-rechargeable portable telephone device in which electricity is generated by movements made in any direction, includes an eccentric pendulum transmission device which causes rotation of an output shaft in response to movement of the telephone body. The output shaft is connected to and causes rotation of the shaft of a flat rotary electric generator The flat rotary generator includes at least one disc-shaped magnetic pole structure and at least one toroidal coil structure arranged such that the toroidal coil structure cuts magnetic lines generated by the disc-shaped magnetic pole structure to generate electric energy, when the shaft is rotated. The generated energy is accumulated by the energy storage element of an energy storage circuitry system and released when the accumulated electrical energy in the energy storage element exceeds a predetermined voltage to charge a rechargeable battery for the portable telephone.

Claims

1. A self-rechargeable portable telephone, comprising:

a portable telephone body including telephone circuitry;

an eccentric pendulum transmission device for converting movement of the telephone body into rotation of an output shaft;

a flat rotary generator including a shaft that is rotated in response to rotation of the eccentric pendulum transmission device output shaft to cause relative rotation between a toroidal coil structure and a disc-shaped magnetic pole structure and induce a current in the toroidal coil structure; and

a rechargeable battery charged by the induced current.

2. The self-rechargeable portable telephone according to claim 1, wherein the eccentric pendulum transmission device includes an eccentric pendulum arranged to be swung by an external force in any direction and for driving a gear assembly to generate the transmission force on the output shaft in order to drive the rotating shaft of the flat rotary electric generator.

3. The self-rechargeable portable telephone as claimed in claim 1, wherein the flat rotary generator includes at least one toroidal coil structure and at least one parallel disc-shaped magnetic pole structure on one side of the at least one toroidal coil structure, the at least toroidal coil structure being arranged to cut through magnetic lines generated by the at least one disc-shaped magnetic pole structure when the generator shaft is rotated.

4. The self-rechargeable telephone as claimed in claim 3, wherein the toroidal coil structure and the disc-shaped magnetic pole structure are not provided with a permeable coil structure.

5. The self-rechargeable telephone as claimed in claim 1, further comprising an energy storage circuitry system for accumulating electrical power supplied by the flat rotary generator and releasing the power to charge the battery when an accumulated voltage level reaches a predetermined voltage level.

6. The self-rechargeable telephone as claimed in claim 5, wherein the energy storage circuitry system includes an energy storage element and a voltage boosting circuit for regulating supply of power to the energy storage element used on feedback from the energy storage element.

7. The self-rechargeable telephone as claimed in claim 5, wherein the energy storage circuitry system includes on energy storage element;

a comparison circuit for comparing a voltage level of the energy storage element with a predetermined voltage level and for generating a control signal; and

a charging circuit for releasing charging power from the energy storage element to the rechargeable battery in response to said control signal.

8. The self-rechargeable telephone as claimed in claim 1, further comprising at least one protection circuit for protecting the telephone body and the rechargeable battery.
