Abstract:
A wireless mouse capable of generating and accumulating electrical energy, comprising:a rolling ball; a first rolling wheel, which longitudinally props up the rolling ball in order to detect the displacement of the wireless mouse projected along an X-axis; a second rolling wheel, which transversely props up the rolling ball in order to detect the displacement of the wireless mouse projected along a Y-axis; an auxiliary rolling wheel, wherein the auxiliary rolling wheel, the first rolling wheel, and the second rolling wheel together prop up the rolling ball so that the rolling ball is kept in a certain rolling position; a first power generating device for transforming the dynamic energy produced by revolutions of the first rolling wheel to electrical energy; a second power generating device for transforming the dynamic energy produced by revolutions of the second rolling wheel to electrical energy; a power storage device for storing electrical energy generated by the first power generating device and the second power generating device; and a radio frequency (RF) transmitting module for transmitting a moving signal of the wireless mouse.
