Embodiment Construction

[0016] Such as Figure 1-6 As shown, the hexacopter frame that can be folded and unfolded autonomously is composed of figure 1 parallelogram mechanism, figure 2 A system that integrates the rotor baffle and the limit buckle.

[0017] Such as figure 1 , is a parallelogram mechanism: 1 crank upper plate, 2 crank middle plate a, 3 crank middle plate b, 4 crank lower plate, 7 lower center plate, 8 connecting rod, 10 sleeve, 11 long steel shaft, 12 support arm, 13 end caps. The frame of parallelogram mechanism is determined by the connecting line of the center of 7 lower central plates and the axis of 12 support arm roots. The crank is composed of 1 crank upper plate, 2 crank middle plate a, 3 crank middle plate b, 4 crank lower plate and the long steel shaft and sleeve in the middle, and the 8 connecting rods of the three pairs of collinear support arms are respectively The plane between the 1 crank upper plate and the 2 crank middle plate a, the 2 crank middle plate a and t...

Abstract

An aircraft rack capable of being folded and expanded automatically is designed through inspiration from a mechanical aperture tuning device of a camera lens and is composed of a central worm-and-gear gear motor, an upper central plate, a lower central plate, a crank, a connecting rod, a plurality of supporting arms and a rotor baffle so that a six-rotor aircraft can be folded to form a compact regular hexagon structure in a manner of being driven by a motor arranged at the centre of the rack. Top parts of adjacent rotors are arranged as close as possible and are regarded as vertexes of the regular hexagon structure. The positions of the rotors are relatively fixed so that a geometric size of the six-rotor aircraft can be greatly reduced. When the central motor rotates in a reverse direction, the supporting arms of the six rotors can be expanded automatically.

Description

technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to a six-rotor aircraft frame that can be folded and unfolded independently. Background technique [0002] The hexacopter is a relatively common and typical small aircraft, which is widely used in military reconnaissance, resource survey, civil aerial photography and other technical fields. Due to the simple mechanical structure of this type of aircraft, strong maneuverability and controllability, vertical take-off and landing, strong load capacity, and high safety factor in the event of a single engine failure, it is suitable for use in narrow spaces or complex terrain environments. However, the support arms of common hexacopters are mostly integral structures, and are integrated with the fuselage. The geometric size is relatively large, and it is not easy to carry. Even though some hexacopters adopt a structure with foldable support arms to reduce the size of the struct...
