Self-generating wireless mouse and mouse pad

Abstract

The invention relates to a self-generating wireless mouse and a mouse pad. One or more magnets are arranged in the mouse pad; the magnets on the same horizontal line are identical in the NS pole direction; the magnets on two adjacent horizontal lines are opposite in the NS pole direction; a rectifier module, an electric energy storage module, an electromagnetic induction module and a voltage stabilizing diode are arranged on a circuit board in the wireless mouse; the positive output end and the negative output end of the rectifier module are respectively connected with the positive end and the negative end of the electric energy storage module; the output end of the electromagnetic induction module is connected with two ends of the rectifier module and the electric energy storage module after serially connecting the rectifier module and the electric energy storage module; and the positive connection end and the negative connection end of the voltage stabilizing diode are respectively connected with the positive end and the negative end of the electric energy storage module. The self-generating wireless mouse provided by the invention has the advantages of high charging efficiency, high self-generating voltage, and long service life of the power supply by adopting the non-contact power generation method and a novel rectifying and charging circuit, and can supply power by itself during normal movement of the mouse.

Description

technical field [0001] The invention relates to a wireless mouse of computer peripheral accessories, in particular to a self-generating wireless mouse and a mouse pad. Background technique [0002] The website http: / / www.billwang.net / ?act=view&id=34560 discloses the document: a leaf-shaped self-generating wireless mouse, which can generate electricity by itself, and brings back the scroll wheel that disappeared in the optical age. At the same time, the scroll wheel will convert this movement on the horizontal plane into rolling and then convert it into electricity through the internal motion mechanism for the use of the wireless mouse itself. [0003] "Application of Electronic Technology", Volume 37, Issue 9, 2011, page 142. A design circuit of a wireless mouse with non-contact power supply is disclosed. The non-contact power transmitting device adopts USB power supply, and generates a 138 kHz high-frequency oscillation voltage through a self-excited oscillation circuit; t...
