Rotating fixed structure of main wing and outer wings of unmanned aerial vehicle

Abstract

The invention relates to a rotating fixed structure of a main wing and outer wings of an unmanned aerial vehicle. The rotating fixed structure of the main wing and the outer wings of the unmanned aerial vehicle comprises a connecting rod and a rotating assembly which sleeves one end of the connecting rod, a sleeve sleeves the rotating assembly, and a third outer wing is fixed to the other end of the connecting rod. The main wing is fixed to the outer side of the rotating assembly, two screw rotating holes formed central symmetrically are formed in the surface, near one end of the main wing, ofthe rotating assembly, a second outer wing and a first outer wing are fixedly arranged on the middle part of the connecting rod, two screw holes are formed in the middle part of the first outer wing,and fixed screws are rotatably arranged in each of the screw holes. According to the rotating fixed structure of the main wing and the outer wings of the unmanned aerial vehicle, the connecting rod and the rotating assembly are connected through a rotating embedded structure between the two central symmetrical screw rotating holes arranged on the rotating assembly and the fixed screws arranged onthe rotating assembly, the connection mode is convenient and easy to replace the main wing or the outer wings, and the unmanned aerial vehicle can be designed as a streamline structure to reduce theflight resistance by reducing the dimensions of the three outer wings in sequence.

Description

technical field [0001] The invention relates to the technical field of UAV component connection, in particular to a rotation-fixed structure of a UAV main wing and an outer wing. Background technique [0002] UAV is the abbreviation of unmanned aircraft. It is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. From a technical point of view, UAV can be divided into unmanned fixed-wing aircraft, unmanned Vertical take-off and landing aircraft, unmanned helicopters, unmanned multi-rotor aircraft and unmanned parawing aircraft, etc. Compared with manned aircraft, unmanned aerial vehicles have the characteristics of small size, low cost, convenient use, and strong battlefield survivability. The fixed-wing UAV is composed of fuselage, main wing, outer wing and tail wing. The main wing mainly plays the role of controlling the flight of the UAV fuselage, while the outer wing controls the direction and speed of the fuselage f...

Problems solved by technology

However, the connection between the main wing and the outer wing of existing UAVs mostly adopts the direct plugging method. The direct plugging connection method is easy to cause the gap between the main wing and the outer wing due to the aging of the equipment during the flight of the UAV. The light ones will lead to the failure of the mission, and the serious ones will directly lead to the fall of the UAV and cause economic losses.
