Problems solved by technology

However, multi-rotor drones also have their own development bottlenecks: 1. In order to increase the load capacity of multi-rotors, the number of blades is increased, resulting in a decrease in the reliability of the drone; 2. The body structure of the drone is complex and fixed. Disassembly is not conducive to the upgrade and transformation of drones in the later stage, and the expansion ability is poor

Abstract

The invention provides a multi-rotor unmanned aerial vehicle (UAV) comprising a fuselage and a casing which is streamlined, wherein the fuselage covers the casing; the fuselage comprises roll shaft groups; the fuselage is provided with rotating shafts at both sides; propeller arm assemblies are rotatably arranged at the rotating shafts; each propeller arm assembly comprises propeller arms and a fixing box for mounting the propeller arms; each fixing box is connected with a folding mechanism; a blade assembly is arranged at the first end of each propeller arm; each blade assembly comprises a power box mounted on the corresponding propeller arm and a blade connected with the power box; and the propeller arm assemblies and the blade assemblies are symmetrically arranged relative to the fuselage. By using the mechanism, the multi-rotor UAV of the invention has the advantages of small weight, simple structure of the fuselage and strong ability to later upgrade, renovation and expansion; in addition, the multi-rotor UAV can ensure a good balance in the course of flight and the airworthiness of the multi-rotor UAV is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle. Background technique [0002] At present, common aircraft are usually divided into fixed-wing, helicopter and multi-rotor (four-rotor is the most mainstream), and multi-rotor UAV is defined as a special unmanned helicopter with three or more rotor axes. [0003] In recent years, due to the excellent operational performance of multi-rotors, multi-rotors have quickly become the mainstream of small UAVs. Multi-rotor UAVs can take off and land vertically, and can hover in the air after takeoff. It is easy to control the flight range and is relatively safe. However, multi-rotor drones also have their own development bottlenecks: 1. In order to increase the load capacity of multi-rotors, the number of blades is increased, resulting in a decrease in the reliability of the drone; 2. The body structure of the drone is complex and fixed. Disas...
