Technical Field

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

[0002] Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian field, drones + industry applications are the real rigid demand for drones; their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.

[0003] In the Chinese utility model patent application publication specification CN207106896U, a parachute throwing device for a drone is disclosed, comprising a fuselage, a storage bin is provided on the inner side of the fuselage, a card seat is installed on the inner side of the storage bin, a slide bar is installed on both the left and right ends of the inner side of the card seat, the slide bar is connected with the card seat, a plug rod is installed on the inner side of the slide bar, a third gear is installed on the bottom end of the plug rod, the third gear is meshed with the plug rod, and a transmission rod is installed on the inner side of the third gear. When the parachute needs to be separated from the fuselage, the drone parachute throwing device starts working by connecting the power motor of the drone itself through the control motor, drives the third gear to rotate through the transmission rod, drives the plug rod to move through the third gear, and the plug rod is separated from the inner side of the slot, so that the connector can move, so that the parachute is separated from the drone, so that the landing machine is firmly connected to the drone under normal circumstances, and can be quickly separated to ensure the safety of the drone when separation is required, but the device only relies on unilateral ejection to throw the parachute, so that the speed of opening the parachute is relatively slow and the efficiency is low. For this reason, we propose a parachute throwing device for a drone. Utility Model Content
