Description

Technical Field

[0002] In order to reduce the flight safety accidents of drones, many existing drones are equipped with rotor protection structures. For example, the utility model patent with publication number CN210618483U proposes a drone rotor protection structure and a drone. The patented technical solution installs a protection frame body at the rotor of the drone, and the protection frame body structure is fixedly connected to the drone's arm. When the drone gradually flies towards external objects such as buildings or tree trunks, the protection frame body will directly collide with the external objects, thereby protecting the rotor from damage.

[0003] Although the arc radius of the protection frame body in the above structure is larger than the radius of the propeller, so that the propeller can be protected when rotating; however, the protection frame body is not at the same horizontal position as the propeller. When encountering a building protruding outward like a balcony, the propeller will still collide with the building, so the anti-collision structure needs to be improved. Utility Model Content
