Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a loading device for unmanned aerial vehicles. Background Art

[0002] Unmanned aircraft, referred to as "drones", are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by on-board computers. Drones can carry a variety of items, such as cameras, sensors, medicines, food, etc. Carrying drones are used in many fields such as agriculture, logistics, and rescue. There are at least the following disadvantages in the use of existing drone carrying devices: 1. The existing drone carrying devices are often fixed on the drone during use, and the disassembly and installation are relatively cumbersome, which affects the operating efficiency in an emergency; 2. The existing drone carrying devices are often rectangular boxes or frames. During the flight of the drone, the windward side of the box will add greater resistance to the drone, thereby increasing the burden on the drone and causing excessive load on the motor and battery. Therefore, we have introduced a carrying device for drones. Utility Model Content
