Abstract

The present invention relates to a self-generating wrist ball which includes a ball-shaped housing, a revolution ring, a flywheel and a generating and lighting mini-module. The ball-shaped housing has a plurality of protruding arched pieces to enhance the light-concentrating effect and to increase the stability when the fingers hold the wrist ball. The generating and lighting mini-module includes at least two rotor aggregates within flywheel and at least two stator aggregates corresponding to said rotor aggregates being fixed on the revolution ring. The wrist ball is self-generating in operational state by means of the impulse excitation created at the rotational moment of the wrist ball. In addition, the effect of magnetic field line can be enhanced by means of magnets and magnetic metal plates of the rotor aggregates and the stator aggregates. Furthermore, the same magnetic poles of both magnets are arranged in opposite way to prevent the flywheel from interference in rotation.

Claims

1. A self-generating wrist ball comprising:

a ball-shaped housing having a top housing and a bottom housing both of which are connected by radio frequency as one hollow body, said top housing being provided with a circular opening at the top thereof;

a bottom housing disposed at support rim on the inside of the top of said bottom housing and rotatable thereon, two connecting holes being arranged at both sides of said support rim;

a flywheel having a central shaft pivotably connected to said connecting holes of said revolution ring so as to be received within said top and bottom housings, an annular ridge being disposed at the center of the surface of said flywheel and provided with a through hole;

wherein a plurality of protruding arched members are arranged on the connection rim of said top and bottom housings, thereby forming a plurality of protruding arched pieces at regular intervals when both top and bottom housings are combined as said ball-shaped housing, and

wherein a generating and lighting mini-module having at least two rotor aggregate aggregates and at least two stator aggregates is arranged on said revolution ring and said central shaft of said flywheel, and

wherein said rotor aggregates are disposed opposite each other on the inner side of said flywheel to make 360°

rotation with said flywheel, and said stator aggregates corresponding to said rotor aggregates are fixed on the inner side of said revolution ring;

accordingly, said rotor aggregates are tangent to said stator aggregates when said rotor aggregates is rotated; and

wherein said rotor aggregates includes a coil and a T-shaped iron core inside a modularized housing, and a first magnet is provided at the bottom of said T-shaped iron core, and a first magnetic metal plate is fitted to the bottom of said first magnet, and at least one light-emitting diode fastened on said modularized housing is connected to the coil, thereby forming a modularization type; and

wherein said stator aggregate opposite to said T-shaped iron core includes a second magnet, and a second magnetic metal plate is disposed at the outer side of said second magnet.
