The embodiment of the invention discloses a propeller structure capable of reducing cavitation phenomenon, which comprises a propeller hub and a propeller blade, the propeller blade is foldably arranged on the propeller hub, and the propeller blade is respectively provided with a propeller tip end and a propeller root end; in the direction from the propeller root end to the propeller tip end, each propeller blade is sequentially provided with a plurality of sections, and the shapes of the sections are gradually changed. The technical problem that in the prior art, according to the blade design of a folding propeller structure for power mode switching, it is difficult to meet appearance adaptation of a folding function specific structure and the power efficiency requirement under the appearance adaptation at the same time is solved.
本发明实施例公开了一种减消空化现象的螺旋桨结构,包括桨毂和桨叶,所述桨叶可折叠式设于所述桨毂,所述桨叶分别具有桨尖端和桨根端;沿着所述桨根端至所述桨尖端的方向,所述桨叶依次具有若干个截面,所述若干个截面的形状逐渐变化。解决了现有技术中针对动力模式切换的折叠式螺旋桨结构的桨叶设计,难以同时满足对折叠功能特定结构的外形适配以及在该外形适配下的动力效率要求的技术问题。
