Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a unmanned aerial vehicle capable of protecting a propeller. Background Art

[0002] Multi-rotor drones, also called multi-axis drones, can be further divided into quad-rotors, hexa-rotors, octa-rotors, etc. according to the number of propellers. It is generally believed that the more propellers there are, the smoother the flight and the easier the operation. Multi-rotor drones have the advantages of being foldable, vertical take-off and landing, hovering, and having low site requirements, and are favored by the general public.

[0003] However, the propellers of most drones currently in use are exposed, which makes it easy for the propellers to touch the rotors when they are stored. The propellers are made of relatively soft material and are easily damaged, and there is no protective device to protect them. At the same time, in order to increase the landing stability of the drone in the prior art, springs are generally used for buffering. However, due to the performance of the springs themselves, a strong reaction force will be generated after being squeezed, which affects the landing stability of the drone.

[0004] To this end, we propose a UAV with propeller protection. Utility Model Content
