Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle equipment, in particular to a unmanned aerial vehicle with an anti-collision device. Background Art

[0002] Unmanned aerial vehicle (UAV), also known as "drone", is an unmanned aircraft that is controlled by radio remote control equipment and self-contained program control devices, or is operated completely or intermittently autonomously by an onboard computer.

[0003] Compared to manned aircraft, drones are often better suited for tasks deemed "dull, dirty, or dangerous." Drones can be categorized by application into military and civilian applications. In the military, drones are divided into reconnaissance and target drones. In the civilian sector, drones combined with industrial applications represent a real necessity. 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 production, and the creation of romance have greatly expanded the uses of drones. Developed countries are also actively expanding industrial applications and developing drone technology.

[0004] Drones are prone to collision accidents during flight, and the existing anti-collision structure of drones is limited in protection angle and cannot provide all-round protection for drones, which makes it easy for drones to be damaged during flight. In order to solve this technical problem, a drone with an anti-collision device is proposed. Utility Model Content
