  • Propeller apparatus of air mobility
    Patent number: 11685513
    Abstract: A propeller apparatus of an air mobility includes a housing having an inner space, where multiple slits are formed along a circumferential surface of the housing to extend in a vertical direction; a driving unit having connection portions formed to match respective ones of the slits in the housing; multiple link units configured to match the respective ones of the slits in the housing, where the link units are rotatably connected to the connection portions, respectively, of the driving unit; and multiple wing units configured to be rotated in a manner of being linked with the link units, which rotate when the driving unit moves up and down, thereby being folded to or deployed from the housing. The propeller apparatus is configured to prevent an accident due to scattering of a propeller when the air mobility falls, and to improve space utilization during storage of the air mobility.

  • Propeller apparatus of air mobility
    Patent number: 11679864
    Abstract: A propeller apparatus of an air mobility is arranged such that a propeller is configured to fold when the air mobility crashes, thereby preventing additional accidents caused by fragments generated by the propeller hitting the ground, and enabling the propeller to be reused by unfolding the folded propeller after the air mobility lands.
