Device and method for position alignment of wireless charging coil for unmanned aerial vehicles

Abstract

The invention provides a wireless charging coil position alignment device for drones and a method thereof, comprising a base, several rotating charging coil adjustment structures evenly arranged in the circumferential direction of the base, and several driving coils at the center of the base. The rotary charging coil adjustment structure is a power drive mechanism that moves in a circle along the base, and the initial orthographic projection position above the power drive mechanism is also equipped with a charging coil position alignment elastic correction structure in the center, a touch panel, and wireless charging for drones. Positioning of the electronically controlled drive unit. The beneficial effects of the present invention are: the distance sensor installed near the charging receiving end of the drone can quickly and accurately measure the distance between the charging receiving end of the drone and the touch panel on the top surface of the charging coil at the center of the alignment elastic correction structure. The orthographic projection distance between them can quickly complete the accurate alignment of the power transmitting coil and the power receiving coil.

Description

technical field [0001] The invention relates to the technical field of wireless charging for drones, in particular to a position alignment device and method for wireless charging coils for drones. Background technique [0002] The short battery life of drones is a common problem of current drones. The ability of drones to perform tasks autonomously is severely limited by battery life. Most of the current solutions are to set up electromagnetic induction wireless charging platforms on the flight route. However, these The wireless charging platform also has the problem that it is difficult to quickly realize the accurate alignment of the power transmitting coil and the power receiving coil. Therefore, the current wireless charging solutions for drones generally have the disadvantages of low charging efficiency or long time-consuming coil alignment. [0003] At present, the mainstream wireless charging technology in the market mainly uses the following three methods: electromag...
