[0002] At present, mechanical automatic unhooking devices have been widely used in air cargo transportation and airdrop missions. These devices mainly realize the mounting and release of cargo through mechanical structures, and use mechanical elements such as springs, pins and levers to control the unhooking process. Although mechanical automatic unhooking devices perform well in some applications, they still have the following significant shortcomings: There is a risk of unhooking in the air: During the flight, if there are large maneuvers or weightlessness, the mechanical automatic unhooking device may accidentally unhook, causing the cargo to fall off in the air, posing a safety hazard. After the cargo touches the ground, it may be impossible to open the hook again: After the cargo touches the ground, the hook of the mechanical unhooking device often gets stuck and cannot be opened again, increasing the difficulty of recovering the cargo and reloading. The mechanical automatic unhooking device cannot be accurately thrown in the air, which is extremely inconvenient in tasks that require air delivery of cargo. Utility Model Content
