Wireless passive variable input device based on wireless energy transmission

Abstract

The invention discloses a wireless passive variable input device based on wireless energy transmission. The wireless passive variable input device comprises a wireless variable input device body and a wireless input device receiver, wherein in the wireless variable input device body, a wireless energy receiving circuit is respectively connected with a display screen, a touch screen, a first micro-processing unit, a first modem and a first antenna, the first modem is respectively connected with the first micro-processing unit and the first antenna, and the first micro-processing unit is further respectively connected with the display screen and the touch screen; and in the wireless input device receiver: a universal serial bus (USB) interface forms a circuit with a wireless energy transmission circuit, a second antenna, a second modem and a second micro-processing unit. The wireless passive variable input device achieves wireless transmission of energy, does not need any cable or energy storage devices including batteries, and is flexible and safe to use, well-adapted, and suitable for business, industry and house using and even for field severe environments.

Description

technical field [0001] The invention relates to a wireless passive variable input device, in particular to a wireless passive variable input device based on wireless energy transmission. Background technique [0002] Traditional input devices use wired connections. The connecting wire brings a lot of inconvenience to users during use, has poor flexibility, and is very unattractive in appearance. [0003] Some recent wireless input devices (such as wireless keyboards) avoid the shortcomings of traditional wired input devices through wireless communication technologies such as Bluetooth. But it only realizes the wireless transmission of signals, and the input device part must rely on battery power. It needs to replace the battery regularly during use, which is very inconvenient. In addition, extensive use of batteries will lead to an increase in heavy metal pollution and endanger the environment. [0004] With the widespread application of display screens, users' requirem...
