Four-rotor aircraft with improved structure

Abstract

The invention provides a four-rotor aircraft with an improved structure, and belongs to the technical field of aircrafts. The four-rotor aircraft with the improved structure comprises an aircraft bodyand four flying devices. The flying device comprises a rotor wing, a first motor, a deformation bracket and a connecting mechanism. The deformation bracket comprises a first parallelogram structure and a second parallelogram structure. The first parallelogram structure comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. The first motor isinstalled on an upper side face of the aircraft body. An end part of an output shaft of the first motor is rotatably connected with one end of the first connecting rod. The upper side face of the aircraft body is vertically provided with a fixing column. The top of the fixing column is fixedly connected with the middle of the first connecting rod. The other end of the first connecting rod is successively hinged with one end of each of the second connecting rod, the third connecting rod and the fourth connecting rod, and the other end of the fourth connecting rod is fixedly connected with theoutput shaft of the first motor. The connecting mechanism is capable of adjusting a distance between the rotor wing and the aircraft body through rotation of the first motor. The four-rotor aircraft with the improved structure is capable of adjusting a distance between the rotor wings according to the need, and improving the flying effect of the aircraft.

Description

technical field [0001] The invention belongs to the technical field of aircraft and relates to a quadrotor aircraft with an improved structure. Background technique [0002] With the continuous development of technology, aircraft are becoming more and more popular. The quadrotor aircraft is a kind of aircraft. The quadrotor aircraft is driven by four sets of motors and has the characteristics of stable flight, hovering, side flight and inverted flight. The quadrotor aircraft uses four rotors as the direct power source for the flight, and the rotors are symmetrically distributed in the front, rear, left and right directions of the body. The four rotors are at the same height plane, and the structures and radii of the four rotors are the same. Rotate clockwise, the other two rotors rotate clockwise, the four motors are symmetrically installed on the bracket end of the aircraft, and the flight control computer and external equipment are placed in the middle space of the bracke...

AI Technical Summary

Problems solved by technology

When flying, the farther the distance between the four rotors is, the more stable the aircraft will be. If the length of the bracket is lengthened, the flexibility of the aircraft will be reduced
