Problems solved by technology

[0004] During the starting and working process of the above-mentioned unmanned aerial vehicle, the propeller and the transmission part can be well connected, but when the unmanned aerial vehicle suddenly slows down or the acceleration changes greatly, the center base and the transmission part are prone to loosening. When the vibration amplitude of the aircraft is large, the center base and the transmission parts are also prone to loosening, which may cause the propeller to shoot.
In addition, when the propeller is disassembled from the transmission parts, tools are needed to complete the operation, which is inconvenient

Abstract

The invention discloses a propeller device and an unmanned aerial vehicle. The propeller device comprises a propeller and a transmission part. The transmission part comprises a driven base capable of being driven to rotate and an elastic abutting part. The propeller comprises a center base body and propeller blades connected with the center base body. The driven base is fixedly connected with the center base body, and a containing groove used for containing the elastic abutting part is formed between the driven base and the center base body. The elastic abutting part is located in the containing groove and connected with the center base body and the driven base in an abutting mode. Compared with the prior art, the technical scheme can improve the structure reliability and the installation convenience of the propeller device.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a propeller device and an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicles are widely used in the fields of surveillance, investigation, detection and photography for some military or civilian purposes. The UAV realizes vertical take-off and landing, flight and hovering actions through the lift of one or more propellers. The blades of the propeller are installed on a central base body, and the central base body is connected with the driving device through the transmission part. When the unmanned aerial vehicle is working, the driving device drives the propeller to rotate. [0003] Such as figure 1 As shown, in the prior art, the central seat body 11 of the propeller is screwed to the transmission part 20 . With this structure, the tightening direction of the center base body 11 is consistent with the rotation direction of the pr...
