Problems solved by technology

[0004] In such an installation method, whether it is assembled by the manufacturer or the user, the motor 12, the propeller seat 13 and the propeller 14 must be aligned with the corresponding holes first, and the operation is very inconvenient
Moreover, if the user assembles the motor 12, paddle holder 13, and paddle 14 by himself, there are still problems such as trivial packaging and error-prone, which is not conducive to shipment control

Abstract

The invention relates to a portable unmanned aerial vehicle, propeller blade rotating assemblies, rotating systems as well as an assembling method of the rotating systems. Each propeller blade rotating assembly comprises a propeller seat, propeller blades and connecting shafts, wherein first connecting holes which are cut-through are formed in the propeller seat; a second connecting hole which is cut-through is formed in each of the propeller blades; and each of the connecting shafts is arranged in the corresponding first connecting hole and the corresponding second connecting hole in a penetrating manner, and is in interference fit with the corresponding first connecting hole and in clearance fit with the corresponding second connecting hole. Each of the rotating systems comprises a propeller blade rotating assembly and a motor connected with a fastener, and each of the fasteners is arranged in the corresponding connecting shaft in a penetrating manner and is at least combined with the propeller seat. The portable unmanned aerial vehicle comprises a folding fuselage and a plurality of rotating systems connected with the fuselage. According to the portable unmanned aerial vehicle, the propeller blade rotating assemblies, the rotating systems as well as the assembling method disclosed by the invention, the assembly, replacement and maintenance operation processes of the portable unmanned aerial vehicle are simplified.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a portable unmanned aerial vehicle, its blade rotating assembly, a rotating system, and an assembly method for the rotating system. Background technique [0002] According to the flight characteristics, UAVs are mainly divided into fixed-wing, rotary-wing and flapping-wing. Among them, the rotary-wing UAV has the characteristics of small size, simple structure, and relatively flexible control. It can take off and land vertically and hover freely. It can also adapt to various natural environments, has the advantages of autonomous flight and landing capabilities, and can operate in complex and dangerous environments that are not suitable for humans to enter. It has become more and more important in recent years. [0003] Figure 1a to Figure 1c A rotor drone is shown, which has four rotors 11 , and each rotor 11 is composed of a motor 12 , a propeller base 13 and two blades ...
