Embodiment Construction

[0029] A high-reliability tilt-rotor unmanned aerial vehicle of the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0030] A kind of high-reliability tilt-rotor unmanned aerial vehicle of the present invention comprises frame 1, and the center of described frame 1 is provided with flight control system 2, and described frame 1 is made of three identical machine arms 11 are docked to form a Y-shaped frame, and the end of each arm 11 is provided with a group of electric power units 12 that are electrically connected to the flight control system 2 and can rotate to set an angle. Three electric power units 12 form an equilateral triangle. In order to ensure the stability of the unmanned aerial vehicle when it lands, each of the arms 11 is also provided with a landing gear 3 that has a buffering effect when the aircraft touches the ground.

[0031] The electric power unit 12 includes a motor base 121 connected to...

Abstract

The invention discloses a high-reliability unmanned aerial vehicle with tilt rotors. The high-reliability unmanned aerial vehicle comprises a rack, wherein a flight control system is arranged at the center of the rack, the rack is a Y-shaped rack formed by abutting three same arms, and one group of electric power units which is electrically connected with the flight control system and can set angle by rotating is arranged at the end part of each arm. Each electric power unit comprises a motor base rotatably connected to the end part of each arm, a permanent magnet brushless direct current motor fixed on the motor base, a rotor connected to an output shaft of the permanent magnet brushless direct current motor, and a motor steering server which is connected to one side of the motor base and used for driving the motor base to rotate by taking the arm as a shaft, and the input ends of the permanent magnet brushless direct current motor and the motor steering server are electrically connected with the output end of the flight control system. The high-reliability unmanned aerial vehicle has a capacity of keeping the attitude stable after certain rotor fails, and is variable in structure, for example, a three-rotor horizontal structure can be converted into a dual-rotor vertical structure so that the projection area can be reduced, thereby being suitable for flight in a limited space.

Description

technical field [0001] The invention relates to a multi-rotor unmanned aerial vehicle. In particular, it relates to a high-reliability tilt-rotor unmanned aerial vehicle. Background technique [0002] Multi-rotor aircraft, also known as Multi-rotor abroad, is an aircraft with multiple propellers. Unlike traditional helicopters, multi-rotor aircraft achieves various actions by changing the speed of the propellers. [0003] Compared with traditional single-rotor helicopters, the rotorcraft with vertical take-off and landing and hovering capabilities has the characteristics of simple structure, easy maintenance, small blade lethality, and safe operation. Not only is it playing an increasingly important role in the military field, but it is also widely used in many civilian fields such as disaster rescue, assessment, dangerous environment investigation, traffic inspection and aerial photography. [0004] Existing multi-rotor unmanned aerial vehicles, in the case of failure of ...
