Embodiment Construction

[0024] The present invention proposes a multi-axis aircraft arm connection device, which includes an arm joint 3 , a shaft sleeve 4 and a locking nut 5 . Wherein: the arm joint 3 is fixed between the fuselage upper plate 1 and the fuselage lower plate 2 through two brackets of the machine arm joint. The axle sleeve 4 is loaded into the sleeve of the arm joint 3, and the wing connecting rod 6 is loaded into the axle sleeve and locked by a nut. The sleeve, axle sleeve, lock nut and wing connecting rod of the described machine arm joint are all coaxial.

[0025] The arm joint 3 includes two brackets 7 and a sleeve 8 . The structures of the two brackets are the same, both being square frame structures. There is a support platform on the symmetrical surface inside the frame of the square frame of the two brackets; the surface of each support platform is an arc surface with the same curvature as the sleeve. Screw holes are distributed on the outer surfaces of the frame of the squ...

Abstract

The invention provides an arm connecting device for an unmanned aerial vehicle. The arm connecting device for the unmanned aerial vehicle comprises an arm connector, a shaft sleeve and a locking nut, wherein the arm connector is fixed between an upper body plate and a lower body plate through two supports of the vehicle arm connector. The shaft sleeve is installed in a sleeve of the arm connector. A wing connecting rod is installed in the shaft sleeve and is locked through the nut. The arm connecting device effectively integrates the advantages of screw connection and can be used for connection of a body and an arm of a heavy-duty aircraft, and the problem that in the prior art, an aircraft body and a wing cannot be disassembled or are difficult to disassemble is effectively solved; and the arm connecting device for the unmanned aerial vehicle has the characteristics that the structure is simple, the mechanical strength is high, and secondary disassembly and assembly are rapid and convenient.

Description

technical field [0001] The invention relates to the field of aircraft mechanical structure design, in particular to a high-strength multi-rotor drone arm quick connection device. Background technique [0002] UAVs are widely used and have been involved in many fields, including map surveying, geological surveying, meteorological detection, pesticide spraying and so on. [0003] When the multi-rotor drone is flying, due to the high-speed rotation of the blades, the instantaneous moment generated is relatively large, which has high requirements for the mechanical structure of the entire drone. At present, there are two ways to connect the arms and fuselage of multi-rotor aircraft. One is the integral type, that is, the arm and the fuselage are not detachable; the other is the segmented type, that is, the fuselage and the wings are connected. Separate the two parts. [0004] The rotorcraft with integral structure has higher mechanical strength because the fuselage and wings a...
