A retractable propeller apparatus for an aerial motor vehicle has a structure that enables the propeller to be exposed or hidden depending on whether the aerial motor vehicle is in a high-speed flight or parked position. In particular, the retractable propeller apparatus includes: a base having a mount provided with a space; a propeller unit disposed on the mount and configured to generate an airflow; a cover configured to close the space and movable in a vertical direction with respect to the mount; and a lifting unit disposed on the mount and connected to the cover, and configured to move the cover. The cover selectively closes or opens the space based on an operation of the lift unit such that the propeller unit is operable.
一种空中机动交通工具的可伸缩螺旋桨设备,具有使得能够根据空中机动交通工具是处于高速飞行还是停放位置而使螺旋桨暴露或隐藏的结构。特别地,可伸缩螺旋桨设备包括:基座,其具有设置有空间的安装件;螺旋桨单元,其设置在安装件上并且配置为产生气流;盖,其配置为封闭该空间并且可相对于安装件沿上下方向移动;以及提升单元,其设置在安装件上并连接到盖,并且配置为使盖移动。盖基于提升单元的操作选择性地封闭该空间或打开该空间,使得螺旋桨单元是可操作的。
