Abstract

The invention relates to an anti-collision unmanned aerial vehicle rotor wing assembly that comprises a rotor wing platform; rotor wing arms are evenly distributed on the edge of the rotor wing platform; rotor wings are arranged at the tail ends of the rotor wing arms and driven by a flight motor to rotate, and the anti-collision unmanned aerial vehicle rotor wing assembly is characterized in thatan anti-collision mechanism is arranged at the tail end of each rotor wing arm; the rotor wing arm comprises a first sleeve, a piston rod and a second spring; the second spring is installed in the first sleeve; one end of the piston rod stretches into the first sleeve and makes contact with the second spring, the other end of the piston rod is provided with the rotor wing, one end of the first sleeve is connected with the piston rod, and the other end of the first sleeve is fixedly connected with the rotor wing platform. According to the unmanned aerial vehicle, the rotor wing arms and connecting arms are arranged to be of elastic structures; when the unmanned aerial vehicle touches an obstacle, a buffering effect can be achieved; the rotor wing arms cannot be stressed, and therefore therotor wings and the rotor wing arms are protected against damages.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an anti-collision unmanned aerial vehicle rotor assembly. Background technique [0002] Unmanned aircraft, referred to as UAV, is a new concept equipment in rapid development, which has the advantages of flexible maneuvering, quick response, unmanned flight, and low operation requirements. At present, UAVs have been widely used in the three major fields of military, scientific research, and civilian use, especially in the fields of electric power, communication, meteorology, agriculture, ocean, exploration, photography, patrol, anti-terrorism and explosives disposal. [0003] Since drones need to fly in different environments, the possibility of damage is very high, especially if the rotor part is damaged a little, it will cause imbalance and cause the drone to fall and be damaged. Therefore, in order to solve this problem, prevent Crashing drones ha...
