1. A self-powered wireless mouse apparatus comprising:
a mouse wheel module; and a back-end processing module electrically connected to the mouse wheel module, wherein the mouse wheel module comprises: a mouse wheel comprising a multipolar magnetic body; at lease a stator plate; a plurality of coils arranged on the stator plate; and a rotation shaft connected to the mouse wheel and the stator plate, the mouse wheel rotated opposite to the stator plate, the coils generating induced alternating current voltages, wherein the back-end processing module comprises: an alternating current to direct current conversion circuit electrically connected to the coils; and an energy storing apparatus electrically connected to the alternating current to direct current conversion circuit, wherein the multipolar magnetic body is driven so that the coils generate the induced alternating current voltages when the mouse wheel is rotated; the alternating current to direct current conversion circuit converts the induced alternating current voltages of the coils into direct current voltages and then stores the direct current voltages in the energy storing apparatus to supply power to the self-powered wireless mouse apparatus. |
