Double-purpose wing tilt rotor unmanned aerial vehicle

Abstract

The invention discloses a double-purpose wing tilt rotor unmanned aerial vehicle which comprises a body. A rotating shaft vertically penetrates the body from the side surface, two ends of the rotating shaft are symmetrically distributed about the body, a power mechanism for driving the rotating shaft to rotate is arranged in the body, transfer seats are arranged at two ends of the rotating shaft, propellers are connected on the transfer seats, wings are hinged on the transfer seats and perpendicular to rotating planes of the propellers along the width directions of the wings, turnover mechanisms are arranged on the wings, the wings rotate around transfer seats by the turnover mechanisms, and rotating planes of the wings are parallel to the rotating planes of the propellers. When the unmanned aerial vehicle is in a high-speed level flight state, the wings rotate to the direction perpendicular to the body, and one end of each wing is connected with the body in an overlapped or clamped manner. When the unmanned aerial vehicle is in a vertical lifting state, the wings rotate to the direction parallel to the body. The unmanned aerial vehicle has the advantages that the unmanned aerial vehicle does not easily turn over and is not easily damaged when landing, and lifting force is large and stability of the unmanned aerial vehicle is good when the unmanned aerial vehicle vertically rises and falls.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, in particular to a dual-purpose tilting wing unmanned aerial vehicle. Background technique [0002] The tilting wing UAV is a combination of propeller UAV and fixed wing UAV, which has both propeller vertical lift function and fixed wing high speed and long range function. The existing tilting-wing drones must have two landing gears under the fuselage. Due to the inherent structural limitations of the drone, the span between the landing gears is limited, that is, the range of landing points is small; It is also difficult to achieve a stable landing when the drone lands. When the drone lands, it often lands vertically at a high speed, which will generate a reverse impact force when it lands; under certain conditions, the reverse impact force, The combination of small landing range and uneven ground caused the drone to flip and be damaged when it landed. [0003] Therefore existing tilting...
