Reciprocal vibration type power generator equipped with inner columnar and outer annular magnetic members, a power storage device, a rectifying circuit, and a charging circuit
First Claim
1. A reciprocal vibration type power generator, comprising:
- a housing (100);
a coil set seat (101);
an annular power generation coil set (104) supported by the coil set seat (101) and including output wires (105) that extend through the coil set seat (101) to a space between the coil set seat and the housing (100);
a motion block (110) including an annular outer magnetic member (108 or 117) and a columnar magnet (107), an inner space (111) being formed between the annular outer magnetic member (108 or 117) and a periphery of the columnar magnet (107), wherein said coil set seat (101) and annular power generation coil set (104) extend into said inner space (111) to enable reciprocal relative axial movement between the motion block (110) and the coil set seat (101) when said generator is vibrated, said relative movement between the motion block (110) and the coil set seat (101) causing said columnar magnet (107) and said annular outer magnetic member (108 or 117) to move reciprocally past the annular power generation coil set (104) and thereby generate electric power;
a rectifying and charging circuit (300) included in said housing (100) and connected to the output wires (105) for rectifying the electric power generated in said annular power generation coil set (104);
an anode input/output terminal (410) installed on the housing (100) and connected to an anode terminal of the rectifying and charging circuit (300);
a cathode input/output terminal (420) installed on the housing (100) and connected to a cathode terminal of the rectifying and charging circuit (300), said anode and cathode input/output terminals (410,420) being for inputting electric power from an external source and for outputting electric power from the rectifying and charging circuit (300) to outside the housing (100);
a power storage device (310) included in said housing (100) for storing rectified electric power received from the rectifying and charging circuit (300) and to output the electric power from the rectifying and charging circuit (300) or input the electric power from the external source through the anode and cathode input/output terminals (410,420) installed on the housing (100).

Abstract
A reciprocal vibration type power generator includes a housing, a coil set seat, a power generation coil set surrounding the coil set seat, and a motion block including an outer magnetic member and a columnar magnet. An inner space is formed between the outer magnetic member and a periphery of the columnar magnet to enable reciprocal relative axial movement between the motion block and the coil set seat when the generator is vibrated. A rectifying and charging circuit is connected to the power generation coil set to rectify power induced in the power generation coil set upon movement of the motion block, and to supply the rectified power to a power storage device. The rectifying and charging circuit is also connected to input/output terminals on the generator housing for outputting power to an external device, and for inputting external charging power to the power storage device.
