Multi-rotor-wing unmanned aerial vehicle

Abstract

The invention relates to the field of unmanned aerial vehicles, in particular to a multi-rotor-wing unmanned aerial vehicle. The multi-rotor-wing unmanned aerial vehicle comprises a vehicle body, andthe vehicle body comprises a fuselage and a mount device on the fuselage; and a plurality of vehicle arms are symmetrically distributed on the left side and the right side of the fuselage, one ends ofthe vehicle arms are connected with the fuselage, and the other ends of the vehicle arms are provided with motor seats and brushless motors, wherein the motor seats and the brushless motors are usedfor driving the unmanned aerial vehicle. According to the different positions of the vehicle arms mounted on the fuselage, the vehicle arms are divided into the front part vehicle arms, the middle part vehicle arms and the rear part vehicle arms, wherein taking-off and landing gears are correspondingly mounted in the middle positions of both the front part vehicle arms and the rear part vehicle arms; the action point of resultant force applied to the unmanned aerial vehicle by the brushless motors is a lift force center, and the centers of all the motors are equally distributed on a circle with the lift force center as the circle center; and connecting lines of the centers of the front part motors and the lift force center are not parallel to the front part vehicle arms, connecting lines of the centers of the rear part motors and the lift force center are not parallel to the rear part vehicle arms, and therefore, an intersecting area is formed after extending lines of all the vehicle arms intersect. According to the multi-rotor-wing unmanned aerial vehicle, the vehicle arms are connected to the left side and the right side of the fuselage, a mount and load-bearing space is reservedfor the middle of the fuselage, and the center of gravity of the unmanned aerial vehicle is adjacent to the lift force center, so that the unmanned aerial vehicle is easy to manipulate and stable inflight.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, specifically a multi-rotor unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle, unmanned aerial vehicle (UAV) for short, is a new concept aircraft in rapid development, because of its flexible maneuverability, fast response, no need for manual driving, low operation requirements, and the ability to carry a variety of small equipment Or objects and other characteristics and have been widely used. At present, the application range of drones has been extended to many fields such as civil, scientific research and even military and national defense, especially in electric power, communication, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, anti-drug and anti-smuggling, border patrol, public security, etc. It is widely used in anti-terrorism and other aspects. Its functions of real-time image transmission and real-time on...

Problems solved by technology

And such a layout of the fuselage leads to the divergence of wiring in the fuselage to the surroundings, which in turn leads to messy wiring in the fuselage, especially for models with more than six axes.

And because the arms are evenly distributed on the fuselage, the body space is separated by the arms. If the camera arm is installed at the front of the fuselage, it will block part of the lens, affecting the aerial photography effect and field of view; or when the drone is under the It is necessary to install a large load-bearing object, such as the water tank in the plant protection drone. When installing or removing the object, due to the narrow working space, it is difficult to install and disassemble and even cause the object to interfere with the landing gear.

However, a small number of other drones simply choose to widen or lengthen the body structure to obtain a larger load space. This method causes a large deviation between the center of gravity and the center of lift, and the drone is difficult to control.
