Device and method for millimeter wave wireless charging

Abstract

The embodiment of the invention discloses a millimeter wave wireless charging device which comprises a millimeter wave generator used for generating and emitting millimeter waves, wherein the millimeter waves are used for charging to-be-charged equipment. The device further comprises a laser sight and a rotating platform, wherein the laser sight is fixedly mounted on the millimeter wave generator and used for emitting and receiving laser beams; the laser beams and the millimeter waves are the same in emission direction; the millimeter wave generator is fixedly connected to the outer surface of the rotating platform; the rotating platform is used for adjusting the direction of the millimeter waves emitted by the millimeter wave generator through rotation. The laser sight is further used for calculating the corresponding reflectivity of the received laser beams and generating a first control signal used for controlling the rotating platform to pause rotating and a second control signal used for controlling the rotating platform to rotate according to the reflectivity. After the adoption of the millimeter wave wireless charging device provided by the invention, the wireless charging efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a device and method for millimeter radio wireless charging. Background technique [0002] At present, mobile terminals such as mobile phones are favored by people for their portability and ease of use, and their functions as communication tools are becoming more and more powerful. However, during the use of mobile terminals, due to their limited battery capacity, charging devices are often required. To charge the battery, wireless charging technology, as a more convenient and flexible charging method, is being more and more extensively researched and put into application. [0003] Wireless charging technology mainly uses the principle of electromagnetic induction to generate a magnetic field by inputting an alternating current in a coil, and induces an electromotive force in a nearby coil to generate a current, thereby realizing wireless charging. However, the ...
