1. An air mobility comprising:
a wing portion extending from a fuselage of the air mobility;
a folded portion provided at an edge of the wing portion, configured to extend from the wing portion to form a part of the wing portion during unfolding of the folded portion, and configured to move to overlap with the wing portion during folding of the folded portion so that an area of air resistance in a vertical direction of the wing portion is reduced;
an actuator connected to the folded portion and configured to provide power to the folded portion, so that the folded portion is unfolded or folded to the wing portion by the actuator; and
a controller engaged to the actuator and configured to control the actuator so that the folded portion is folded during vertical takeoff or landing of the fuselage, and configured to control the actuator to unfold the folded portion during cruising of the fuselage,
wherein the wing portion and the folded portion are located to be selectively brought into contact with each other,
wherein the air mobility further includes a hinge portion coupled to lower portions of the wing portion and the folded portion to enable the folded portion to be rotatable with respect to the wing portion,
wherein the actuator is configured to selectively rotate the folded portion around the hinge portion according to a signal of the controller, so that the folded portion is unfolded or folded,
wherein the actuator includes:
a driving device located in the wing portion and connected to the controller to be driven by the controller; and
a connection link coupled to the driving device and the folded portion to unfold or fold the folded portion in a response to driving of the driving device,
wherein the connection link includes:
a first link connected to the driving device and configured to be rotated by the driving device; and
a second link, wherein a first end portion of the second link is pivotally connected to an end portion of the first link and a second end portion of the second link is pivotally connected to a lower portion of the folded portion,
wherein the folded portion is configured to be unfolded or folded as the first link is rotated and displacement of the second link is changed by the driving device,
wherein the wing portion includes a first limiting portion configured to limit a rotational angle of the first link during the unfolding or the folding of the folded portion, and
wherein a portion of the wing portion is recessed from an outer surface of the wing portion to form the first limiting portion having a recess of an acute angle.
