Problems solved by technology

[0004] Although the propeller can be fixed on the motor well by screw fixing, tools are generally required for its assembly and disassembly, which makes the assembly and disassembly of the propeller inconvenient
Although the fixing method through the cooperation of the protrusion and the groove is easy to assemble and disassemble, the cooperation between the protrusion and the groove is easy to loose, which is not conducive to the flight of the aircraft

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] In the embodiment of the present invention, the central hole of the propeller cooperates with the rotating shaft of the motor, and the first buckle part of the propeller cooperates with the second buckle part on the cover of the motor. The two ways of cooperation can be fixed by means of interference fit, etc. Therefore, the assembly and disassembly work between the propeller and the motor can be better completed without tools, and the propeller can be b...

Abstract

The invention provides a power device and an aircraft. The power device comprises a propeller and a motor, wherein the propeller comprises blades (11) and a propeller hub (12) and the motor comprises a stator component (1), a rotor component (2) and a rotating shaft (3). The rotor component (2) comprises a sleeve body (21) and a cover body (22). The propeller hub (12) is provided with a central hole (121) and a first clamping portion (122) and the cover body (22) is provided with a second clamping portion (221). The first clamping portion of the propeller hub and the second clamping portion of the cover body are in clamping fit and the rotating shaft cooperates with the central hole of the propeller hub, so that the propeller is fixed to the motor. According to the invention, the installation and detachment of the motor and the propeller in the power device of an aircraft can be completed conveniently and the concentricity and the perpendicularity of the motor and the propeller can be guaranteed to a certain extent.

Description

technical field [0001] The invention relates to the technical field of flight, in particular to a power device and an aircraft. Background technique [0002] A rotorcraft is a flying device that drives a propeller to rotate to generate power through a motor, thereby realizing space flight. Portable rotorcraft include some UAVs (Unmanned Aerial Vehicles, unmanned aerial vehicles) that complete the flight through ground remote control and other control methods. These aircraft have been widely used due to their relatively low cost and the ability to provide light, flexible low-altitude and low-speed flight. To various civil fields, especially in various geographical surveying and mapping, aerial photography and other fields. [0003] The power plant of existing rotorcraft generally comprises: the motor driver that links to each other with flight controller, the motor that drives propeller to rotate and propeller, is to carry out between motor and propeller and fix propeller th...
