Problems solved by technology

[0004] The technical problem to be solved by this invention is that the existing unmanned aerial vehicles mainly use fixed rotors. If they collide with obstacles during flight, the rotors are easily damaged. The purpose is to provide a new type of unmanned aerial vehicle with folding rotors. The arm structure solves the problem that the existing drones mainly use fixed rotors, and if they collide with obstacles during the flight, the rotors are easily damaged.

Embodiment 2

[0024] The end of the opening 101 away from the telescopic rod 2 also extends along the wall of the sleeve 1 perpendicular to the axial direction of the sleeve 1 . When storing the drone, the handle 4 can be pressed into the end of the casing 1 close to the fuselage of the drone and then screwed into the extension section to lock, and the wings can be folded.

Embodiment 3

[0026] The end of the extension section of the opening 101 extends along the wall of the sleeve 1 parallel to the axial direction of the sleeve 1 to form a bayonet 102 . A bayonet 102 is provided on the extension section to ensure that the handle will not slip out when the wings are folded.

Abstract

The invention discloses a novel folding rotor arm structure of an unmanned aerial vehicle. The structure comprises the unmanned aerial vehicle and a rotor of the unmanned aerial vehicle, wherein a cylindrical telescopic rod is connected to the rotor and connected with a bushing through a spring, one end of the bushing is connected with the unmanned aerial vehicle, the other end is open and matched with the telescopic rod, and the telescopic rod can move freely in the bushing in the axial direction of the bushing; a clamping handle perpendicular to the telescopic rod is further arranged on the telescopic rod, an opening matched with the clamping handle is formed in the bushing and is in the same direction with extension of the bushing. When the unmanned aerial vehicle collides with obstacles, the spring is compressed under stress to prevent the rotor arm from being damaged, and the clamping handle can only move along the opening, so that the problem of rotation of the telescopic rod in the bushing is solved. The novel folding rotor arm structure has the advantages that in the event of a collision, the rotor is prevented from being damaged by compressing the spring; storage is facilitated by the aid of the folding structure.

Description

technical field [0001] The invention relates to a UAV rotor arm, in particular to a novel UAV folding rotor arm structure. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. From a technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protection, selfies, express delivery, disaster rescue, wildlife o...
