Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a remote wireless power supply device for unmanned aerial vehicles. Background technique [0002] Because of its convenient use and good economical advantages, UAVs can replace traditional operating methods in some high-risk and difficult tasks, and have a wide range of applications in intelligent patrol inspection, aerial photography mapping, forest fire prevention and other fields. However, UAVs lack the long-endurance operation capability. In order to ensure the battery life and voyage, it is necessary to establish a power supply device to complete the long-distance, efficient and intelligent power transmission of UAVs. At present, the battery of drones mainly uses chargers for wired charging. The disadvantage is that the cruising range is short, and the battery needs to be disassembled.

Problems solved by technology

At present, the battery of drones mainly uses chargers for wired charging. The disadvantage is that the cruising range is short, and the battery needs to be disassembled. At the same time, the voltage platform and charging interface of different drones are different, resulting in a high degree of personnel participation. , low protection efficiency

[0004] At present, an important factor limiting the development of laser wireless power supply technology is the heat dissipation of the battery board. Excessive temperature rise of photovoltaic cells has a great impact on energy transfer efficiency. Existing heat dissipation methods cannot effectively solve the problem of low energy transfer efficiency caused by high temperature. question

Another important factor limiting the development of laser wireless power supply technology is the problem of the incident angle between the battery board and the laser. During the charging process, the incident angle of the laser cannot be guaranteed to be vertical, which reduces the charging efficiency.

There is also the problem that the charging device cannot be applied to multiple models in the prior art
