Problems solved by technology

[0005] (1) The limited size of the UAV seriously limits the capacity of the battery, which affects the battery life, and the charging steps of the UAV battery are relatively cumbersome, which affects the work efficiency
[0006] (2) Wired charging has problems such as easy wear and tear of charging equipment and easy generation of sparks
[0007] (3) The battery technology has developed to the bottleneck period, and a larger battery capacity means a larger battery volume and weight, so increasing the battery capacity will definitely affect the maneuverability and lightweight of the UAV
At present, the endurance of drones is mainly limited by battery performance and traditional charging methods

Embodiment 1

[0142] A charging platform for drones proposed by the present invention has a targeted design for the wireless charging system of drones hovering, combining the performance characteristics of drones when the system is loaded and the ability to pick up and use electric energy in the hovering state. Unique, systemic features related to wireless power transfer are also confirmed to exist in this system.

[0143] The present invention establishes the model of the charging platform by comparing and analyzing the characteristics of various charging schemes, and simulates and analyzes the coils to verify the feasibility of the scheme from many aspects. Specifically include the following:

[0144] 1. Wireless charging technology

[0145] 1.1 Electromagnetic Radiation Wireless Charging Technology

[0146] At present, this type of technology is usually implemented in two ways: microwave power transmission (MPT) and laser power transmission (LPT), which can transmit electric energy ove...

Embodiment 2

[0178] Embodiment 2: A method for charging a drone based on wireless charging, specifically including the following:

[0179] 1. Wireless charging method

[0180] There are three main ways of wireless charging, namely resonance coupling, electromagnetic induction coupling and microwave radiation. In addition, there are new ways of using electric field coupling, ultrasonic waves, lasers, etc., but they are still in the initial research stage.

[0181] 1.1 Electromagnetic induction coupling type

[0182] The electromagnetic induction coupling wireless charging technology is proposed based on the theory that a changing magnetic field generates an induced current. Its working principle is similar to the power conversion of a transformer. In this wireless charging system, the coupling of the coils at the transmitting end and the receiving end requires directivity. It is very high, and there is almost no coupling when they are perpendicular to each other. In addition, the distance...
