Abstract

A passive wireless mouse and keyboard based on wireless energy transmission belongs to the field of computer devices. The invention solves the problem that the existing wireless mouse and keyboard often need external power supply for the mouse pad. The passive wireless mouse based on wireless energy transmission of the present invention includes a USB transmission source, a mouse pad and a mouse; the USB transmission source includes a USB plug, a wireless keyboard and mouse data transmission module, an energy excitation circuit and a transmission coil; It is converted into an alternating current with a frequency of f, and an alternating magnetic field is excited in the transmitting coil, the LC resonant circuit in the mouse pad resonates with the alternating magnetic field, and an induced magnetic field is generated around the mouse pad, and the induced magnetic field is generated in the mouse receiving coil The induced electromotive force supplies power to the mouse. The passive wireless keyboard based on wireless power transmission includes a USB transmission source and a keyboard; the LC resonant circuit in the keyboard resonates with the alternating magnetic field, and an induced electromotive force is generated in the keyboard receiving coil to supply power to the keyboard.

Description

technical field [0001] The invention relates to a passive wireless mouse and keyboard based on wireless energy transmission, and belongs to the field of computer devices. Background technique [0002] Keyboards and mice are commonly used computer peripherals. Traditional wireless keyboards and mice can only realize wireless data transmission. Keyboards and mice still need battery power. Frequent replacement of batteries not only brings high cost of use, but also is not conducive to environmental protection. Although a few wireless powered mice have been developed at present, it is often necessary to connect the mouse pad with external power supply, which loses the meaning of "wireless". Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing wireless mouse and keyboard often need to connect the mouse pad with external power supply, which loses the meaning of "wireless", and provides a passive wireless mouse and keyb...
