Technical Field

[0001] The utility model relates to the technical field of a parachute opening mechanism of an unmanned aerial vehicle, in particular to a parachute opening mechanism of an unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles, also known as drones, are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers. The application areas of unmanned aerial vehicles are constantly expanding, and both industrial drones and consumer drones have made great progress, especially small and micro unmanned aerial vehicles represented by multi-rotor unmanned aerial vehicles, which have begun to be widely used in various application fields.

[0003] During the use of drones, drones often crash due to operational errors and other reasons. Therefore, drones often need parachutes for rescue. There is a lack of connection devices between the parachute opening mechanism of the drone and the drone. Secondly, the inside of the parachute compartment does not have a mechanism to throw the parachute out. After the parachute compartment is opened, the parachute can only leave the compartment by itself. Finally, the parachute opening mechanism of the parachute compartment is mostly controlled by explosive bolts, which is costly and may also harm the drone. Therefore, a parachute opening mechanism for a drone is proposed to address the above problems. Utility Model Content
