High-reliability high-stability multi-rotor-wing unmanned aerial vehicle with quick-dismounting function

Abstract

The invention provides a high-reliability high-stability multi-rotor-wing unmanned aerial vehicle with a quick-dismounting function. In order to quickly dismount the unmanned aerial vehicle, the central disc and arms of the unmanned aerial vehicle are split, fan-shaped plates with central angles of more than 180 degrees are arranged on the end surfaces of arm inner parts in arm connecting structures to serve as first limiting convex grooves, fan-shaped plates with central angles of less than 180 degrees are arranged on the end surfaces of central disc inner parts in the arm connecting structures to serve as second limiting convex grooves, and each first limiting convex groove and each second limiting convex groove are clamped together to form a round plate anti-twist structure; meanwhile, in order to prevent twisting of each anti-twist structure, two column positions are added in each connecting structure to reinforce the anti-twist effect, and the arm inner parts are integrally and fixedly connected with the central disc inner parts through thread suites on the outer sides of the formed anti-twist structures, so that the firmness of the unmanned aerial vehicle during flight is guaranteed and the anti-twist function of the arms is improved. The unmanned aerial vehicle has the advantages of simple structure, and has the advantages of quickness for dismounting and convenience for connecting and mounting; especially, the firmness and rigidity of connection are guaranteed, and the flight reliability and stability of the unmanned aerial vehicle are greatly improved.

Description

technical field [0001] The invention relates to a multi-rotor unmanned aerial vehicle, in particular to a multi-rotor unmanned aerial vehicle with high reliability and high stability of quick disassembly and assembly. Background technique [0002] Micro multi-rotor unmanned aerial vehicles with vertical take-off and landing and stable hovering have very broad application prospects in civilian and military fields. Although common micro-miniature unmanned aerial vehicles can take off and land vertically and hover in the air, but due to The fixed connection between the arm and the center plate of a UAV-like UAV adopts ordinary plug or simple screw connection. In the case of high-speed rotating flight of the rotor, especially after long-term use or flight, the connection between the center plate and the arm may become loose or the machine may become loose. The problem of twisting and tilting of the arm causes unbalanced forces on the drone to cause vibration and shaking. As a r...
