Abstract
A wireless mouse capable of generating and accumulating electrical energy. The wireless mouse includes: (a) a first rolling wheel, which longitudinally props up the rolling ball and detects the displacement of the wireless mouse along the X-axis; (b) a second rolling wheel, which transversely props up the rolling ball and detects the displacement of the wireless mouse projected along the Y-axis; (c) an auxiliary rolling wheel, wherein the auxiliary rolling wheel, the first rolling wheel, and the second rolling wheel together prop up the rolling ball to keep the rolling ball in a certain rolling position; (d) at least one power generating device for transforming the dynamic energy produced by revolutions of the first/second rolling wheel to electrical energy; (e) an power storage device for storing electrical energy; and (f) a RF transmitting module for transmitting a moving signal of the wireless mouse and control signals of the left and right buttons.
