Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a propeller gasket for an unmanned aerial vehicle and a propeller base for an unmanned aerial vehicle. Background Art

[0002] The rotorcraft comprises a fuselage, an arm, a driving device and a propeller assembly fixed to the driving device, wherein the driving device drives the propeller assembly to provide lift for the aircraft to fly. In the prior art, the propeller assembly is a foldable propeller assembly for easy storage of the rotorcraft.

[0003] When installing the propeller assembly, it is usually necessary to use gaskets to reduce vibration and prevent wear. The original blade gaskets currently used are made of 3M adhesive, which is easy to loosen and shift, and are not wear-resistant. When the blades are running at high speed, the inside of the gaskets tends to turn black, causing the blades to get stuck. Utility Model Content

[0004] In order to make up for the deficiencies in the prior art, the utility model provides a propeller gasket for a drone, which has the advantages of being wear-resistant, not easy to shift, not turning black when running at high speed, and being green and environmentally friendly.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A propeller gasket for a drone comprises an upper cover and a lower cover connected in a snap-on manner, a gasket core is sandwiched between the upper cover and the lower cover, and a through hole for connecting a propeller base is provided as a whole after the upper cover, the gasket core and the lower cover are connected.

[0007] Furthermore, the bottom surface of the upper cover is provided with a plurality of connecting columns, the top surface of the lower cover is provided with a plurality of embedded hole columns corresponding to the connecting columns, the embedded hole columns are provided with countersunk holes, the countersunk holes are interference fit with the connecting columns, and the cushion core is provided with through holes for the embedded hole columns to pass through.

[0008] Furthermore, the upper cover and the lower cover are both made of Teflon, and the cushion core is made of fiber-reinforced Teflon.

[0009] The utility model also provides a UAV propeller base, comprising the UAV propeller gasket.

[0010] Furthermore, the UAV propeller base also includes a base, on which a connecting shaft is provided, and the connecting shaft is sequentially sleeved with the UAV propeller gasket, the blade, the UAV propeller gasket, and the propeller clamp from bottom to top.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] Compared with the existing gasket, the utility model has higher wear resistance, is not easy to shift during use, does not contain glue, is more environmentally friendly, and the gasket will not turn black inside when running at high speed, thus avoiding the blade from getting stuck.
