Problems solved by technology

However, the above method requires the use of tools to disassemble and assemble the propeller, and the nuts are easy to lose outdoors
[0003] For this reason, the method of embedding nuts at the bottom of the propeller is proposed in the related art to overcome the above-mentioned defects such as complicated disassembly and assembly operations caused by the need for tools, and easy loss of nuts.
However, since the nut and the propeller are made of different materials, the embedding process of the nut is likely to cause problems such as a reduction in the installation accuracy of the propeller.

Abstract

The invention relates to a power device and an aircraft. The power device comprises a motor, a connection component and a propeller. A rotor platform is arranged at one end of the motor, and the center of the rotor platform is provided with a rotation shaft. The bottom face of the connection component makes contact with the rotor platform and is connected with the rotor platform, and the connection component is provided with a through hole matched with the rotation shaft. In addition, the top face of the connection component is recessed downwards to form a clamping groove structure. The propeller comprises a propeller hub and propeller blades. The bottom of the propeller hub is provided with a housing hole and a cylinder-shaped connecting pillar located in the housing hole. The edge of the outer portion of the bottom side of the propeller hub is further provided with a buckle structure. The buckle structure and the clamping groove structure are matched with each other, and the connecting pillar and the rotation shaft are matched with each other, so that the assembly between the propeller and the connection component and the assembly between the propeller and the motor are achieved respectively. According to the technical scheme, the structure complexity of the power device can be lowered, and fast disassembly and assembly of the power device can be achieved.

Description

technical field [0001] The present disclosure relates to the technical field of aircraft, and in particular, relates to a power plant and an aircraft. Background technique [0002] The rotorcraft is driven by the motor to rotate the propeller and generate power to realize the flight of the rotorcraft in space. In the related art, a through hole is opened on the propeller, and after the motor shaft passes through the through hole, the propeller is fastened by a nut. However, the above method requires the use of tools to disassemble and assemble the propeller, and the nuts are easy to lose outdoors. [0003] For this reason, the method of embedding nuts at the bottom of the propeller is proposed in the related art to overcome the above-mentioned defects such as complicated disassembly and assembly operations caused by tool requirements and easy loss of nuts. However, since the nut and the propeller are made of different materials, the embedding process of the nut is likely t...
