Portable unmanned plane, paddle rotating assembly, rotating system and assembling method thereof

Abstract

The invention relates to a portable unmanned plane, a paddle rotating assembly, a rotating system and an assembling method thereof. The paddle rotating assembly comprises a paddle seat, paddles and first and second connection pieces, wherein a running-through first connection hole is formed in the paddle seat; running-through second connection holes are formed in the paddles; the first connection piece is provided with a clamping space, and the second connection piece has a limiting feature; the second connection piece is arranged in first and second connection holes in a penetrating manner and is in clearance fit with the two connection holes; and furthermore, the first connection piece is clamped with the second connection piece through the clamping space and the second connection piece is matched with the paddle seat through the limiting feature, so that the limiting feature and the first connection piece can commonly define the displacement of the second connection piece in the axial direction. The rotating system comprises paddle rotating assemblies and motors connected with the paddle seats and the second connection pieces. The portable unmanned plane comprises a folding plane body and a plurality of rotating systems connected with the plane body.

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 ...

AI Technical Summary

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
