Passive wireless mouse and keyboard based on wireless power transmission

Abstract

The invention discloses a passive wireless mouse and a passive wireless keyboard based on wireless power transmission, belongs to the field of computer devices, and aims to solve the problem that the existing wireless mouse and the wireless keyboard generally require than a mouse pad is externally connected with a power supply. The passive wireless mouse based on wireless power transmission comprises a USB (universal serial bus) emission source, a mouse pad and a mouse, wherein the USB emission source comprises a USB plug, a wireless keyboard-mouse data transmission module, an energy excitation circuit and a transmitting coil; the energy excitation circuit converts a direct current power into alternating current with the frequency f, and excites an alternating magnetic field in the transmitting coil; an LC resonance circuit in the mouse pad generates resonance oscillation with the alternating magnetic field to generate an induced magnetic field around the mouse pad; the induced magnetic field generates induced electromotive force to supply power for the mouse in a mouse receiving coil. The passive wireless keyboard based on wireless power transmission comprises a USB emission source and a keyboard, wherein an LC resonance circuit in the keyboard generates resonance oscillation with the alternating magnetic field; the induced electromotive force is generated in a 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 power 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 transmit data wirelessly. Keyboards and mice still need battery power. Frequent battery replacement not only brings high usage costs, and is not conducive to environmental protection. Although a few wireless powered mice have been developed, they often need to be externally powered on the mouse pad, which loses the meaning of "wireless". Summary 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 externally supply power to the mouse pad and lose the meaning of "wireless", and to provide a passive wireless mouse and keyboard based on wireless power transmission.
