Multi-rotor unmanned aerial vehicle lifting rack

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle lifting rack. The multi-rotor unmanned aerial vehicle lifting rack comprises a cabin bracket, lifting rotors, power equipment, supportingarms and a guide cylinder cover. The middle of the cabin bracket is a position where a manned (cargo-carrying) cabin is arranged, the plurality of lifting rotors are circumferentially distributed at the periphery of the cabin bracket in parallel, and the lower end of each lifting rotor is respectively provided with power equipment for driving the lifting rotor to operate. The power equipment is fixed to the outer wall corresponding to the cabin bracket through a supporting arm, and a guide cylinder cover is vertically arranged outside the lifting rotors. Compared with an existing unmanned aerial vehicle rack, the structural limitation of the existing unmanned aerial vehicle rack and vehicle arms is broken through, so that the manned (cargo-carrying) cabin can be arranged in the middle of the unmanned aerial vehicle lifting rack, and the unmanned aerial vehicle lifting rack has the advantages of convenience in manned (cargo-carrying), high energy conversion rate, simple structure, economy and high practicability; the multi-rotor unmanned aerial vehicle lifting rack is the development direction of multi-rotor manned (cargo-carrying) aircrafts in the future.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a lifting frame of a multi-rotor unmanned aerial vehicle. Background technique [0002] Looking at the world, the unmanned aerial vehicles developed at home and abroad are flourishing, and the unmanned aerial vehicles suitable for carrying people and cargo generally have the following problems: 1. Due to the structural limitations of the existing unmanned aerial vehicle frames and arms, The cargo of the existing cargo-carrying unmanned aerial vehicle is generally hoisted under the unmanned aerial vehicle frame, there is a design that is directly exposed and hoisted under the unmanned aerial vehicle frame, and there is also a closed box designed under the unmanned aerial vehicle frame. The design for loading goods, and the design of binding the goods on or below the frame of the unmanned aerial vehicle, and the existing manned unmanned aerial vehicles have not broken the structur...

[0002] Looking at the world, the unmanned aerial vehicles developed at home and abroad are flourishing, and the unmanned aerial vehicles suitable for carrying people and cargo generally have the following problems: 1. Due to the structural limitations of the existing unmanned aerial vehicle frames and arms, The cargo of the existing cargo-carrying unmanned aerial vehicle is generally hoisted under the unmanned aerial vehicle frame, there is a design that is directly exposed and hoisted under the unmanned aerial vehicle frame, and there is also a closed box designed under the unmanned aerial vehicle frame. The design for loading goods, and the design of binding the goods on or below the frame of the unmanned aerial vehicle, and the existing manned unmanned aerial vehicles have not broken the structural limitations of the existing unmanned aerial vehicle frames and arms; There is no ring-shaped cabin bracket in the middle of the frame of the existing unmanned aerial vehicle, and there is no position for the manned (cargo) cabin; three, the outside of the rotor of the existing unmanned aerial vehicle is generally not provided with a shroud. There are unmanned aerial vehicles that are complex in design and expensive
