Abstract

The invention discloses a passive anti-collision damping multi-rotor drone. Multiple engine arms of same structures are evenly arranged on a baseboard in a concyclic mode, according to the structure of each engine arm, a bearing base is fixed to the baseboard through bolts, a linear bearing is installed in the bearing base, an inner end of a carbon rod penetrates through the linear bearing, the carbon rod is arranged on the linear bearing in a sliding mode, a motor base is fixedly connected with an outer end of the carbon rod, a motor is installed on the motor base, a rotor are installed on amotor shaft, the carbon rod is sleeved with a spring, and the spring abuts between the bearing base and the motor base. The passive anti-collision damping multi-rotor drone has the following characters that the structure is simple, and the whole drone is light in weight; collision can be effectively resisted, and a damping effect is good; after being collided, the passive anti-collision damping multi-rotor drone can fast restore an initial state, so that flying of the drone is safer and more reliable.

Description

technical field

[0001] The invention relates to a rotor unmanned aerial vehicle, particularly a quadrotor and multi-wing (six-wing, eight-wing, etc.) unmanned aerial vehicle with anti-collision and shock absorption functions. Background technique

[0002] Multi-rotor UAV is a new concept weapon equipment in rapid development, which has the advantages of flexible maneuvering, fast response, unmanned flight, and low operation requirements. By carrying multiple types of sensors, drones can realize real-time image transmission and detection of high-risk areas, which is a powerful supplement to satellite remote sensing and traditional aerial remote sensing. At present, the scope of use of drones has been expanded to three major fields: military, scientific research, and civilian use, and it is widely used in fields such as electric power, communication, meteorology, agriculture, ocean, and exploration.

[0003] It is precisely because of the diversity of the environment and the ...
