A fail-safe landing device for cruising drones

Abstract

The invention discloses a fail-safe landing device for a cruise unmanned aerial vehicle. A fail-safe landing device for a cruise unmanned aerial vehicle comprises a machine body. The inside of the machine body is equipped with a cabin, and the inner bottom of the cabin is provided with a The installation slot, the inside of the nacelle is rotatably equipped with a gear ring, the inner side of the gear ring is hinged with a connecting rod, the end of the connecting rod away from the gear ring is hinged with a sealing plate, and the outer side of the gear ring is meshed with a transmission gear. The cruising UAV uses a fail-safe landing device. By installing a parachute in the UAV, when the UAV engine suddenly stops, the rotating ring will be pushed out by the inertial rotation, and then the gear ring will be driven by the reset clockwork. Open the installation slot and the ejection port, the spring plate will eject the parachute, and the drone can land slowly through the parachute, which can reduce the crash rate of the drone, save costs, and prevent the falling drone from being injured people or animals.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a fail-safe landing device for cruising unmanned aerial vehicles. Background technique [0002] UAV is a flying tool that can be remotely controlled. Because it is cheap, easy to operate, and less restricted by terrain, it is currently playing an important role in field construction, exploration, transportation, tourism, rescue and other fields. [0003] When the UAV is cruising, it may be affected by some air factors, such as the collision of flying birds, high-altitude water vapor entering the body, causing the UAV to short-circuit, circuit failure, etc., which will cause the UAV to fall from a high altitude and be damaged, and may also damage the bottom surface people or animals, so we propose a cruise UAV with a fail-safe landing device to solve the problem. Contents of the invention [0004] In order to overcome the above-mentioned deficiencies in the pri...
