Unmanned aerial vehicle and method for operating same
An Unmanned Aerial Vehicle (UAV) according to various embodiments may include: a housing; a motor arranged in an inner space of the housing; a rotor which is rotated by the motor and includes at least one cam structure; and at least one landing member which serves as at least part of the housing and selectively protrudes from the housing depending on interference of the cam structure. An UAV according to various embodiments may include: a housing; at least one rotor blade arranged in an inner space of the housing; and at least one landing member. The at least one landing member may serve as part of the housing in a closed position and protrudes from the housing in an open position such that a load of the UAV can be supported during landing. Other embodiments are also possible.
1. An Unmanned Aerial Vehicle (UAV) comprising:
a housing;
a motor arranged in an inner space of the housing;
a rotor that is rotated by the motor and comprises at least one cam structure; and
at least one landing member,
wherein the at least one landing member comprises a cam interlocking portion,
wherein the cam structure comprises a first inclined portion and a first planar portion oriented in a direction for insertion into the cam interlocking portion,
wherein the cam interlocking portion receives the first inclined portion and then the first planar portion, according to the rotation of the rotor, and
wherein the landing member transitions between forming at least part of the housing and protruding from the housing, according to the receiving by the cam interlocking portion.
2. The UAV of claim 1 , wherein:
the rotor and the at least one landing member are disposed at a center portion of the housing, and
the cam structure of the rotor causes the at least one landing member to protrude from the housing according to a rotational movement of the rotor.
3. The UAV of claim 2 , wherein the housing comprises a plurality of comb pattern unit members spaced apart by a specific interval in a circumferential direction from the center portion of the housing.
4. The UAV of claim 3 , wherein the at least one landing member is configured to form a part of the plurality of comb pattern unit members.
5. The UAV of claim 2 , wherein the at least one landing member comprises:
a body having a specific length;
a hinge arm constructed at a first end of the body and rotatably coupled to the housing; and
a support portion located at a second end of the body facing the hinge arm and disposed to contact a ground surface upon a landing of the UAV.
6. The UAV of claim 5 ,
wherein the cam interlocking portion comprises:
a cam accommodating space disposed at one side of the hinge arm and configured to accommodate the cam structure; and
a protrusion portion disposed at a position controlled by the cam structure inside the cam accommodating space.
7. The UAV of claim 6 , wherein the hinge arm is configured to cause the support portion of the landing member to protrude from the housing by an operation in which the cam structure is inserted to the cam accommodating space to press the protrusion portion in a vertical direction.
8. The UAV of claim 7 , wherein the first inclined portion and the first planar portion are arranged sequentially from a direction in which the cam structure is inserted.
9. The UAV of claim 8 , wherein the cam accommodating space is narrowed in the direction in which the cam structure is inserted by the inclined portion.
10. The UAV of claim 6 , wherein the housing comprises an elastic member configured to press the landing member in a direction corresponding to an outer face of the housing.
11. The UAV of claim 10 , wherein:
the hinge arm is rotatably coupled to the center portion by a hinge pin, and the elastic member comprises a coil-type torsion spring coiled around the hinge pin and configured to press against the landing member by being supported by the center portion.
12. The UAV of claim 2 , wherein:
the at least one landing member comprises at least three landing members, and
the at least three landing members are arranged in a circumferential direction to be equiangular from a center portion of the housing.
13. An Unmanned Aerial Vehicle (UAV) comprising:
a housing;
a motor arranged in an inner space of the housing;
a rotor which is rotated by the motor and comprises at least one cam structure;
at least one rotor blade arranged in an inner space of the housing; and
at least one landing member,
wherein the at least one landing member is configured to form a part of the housing in a closed position and configured to protrude from the housing in an open position, and
wherein, when in the open position, the at least one landing member is configured to support a load of the UAV during landing,
wherein the at least one landing member comprises a cam interlocking portion,
wherein the cam structure comprises a first inclined portion and a first planar portion oriented in a direction for insertion into the cam interlocking portion
wherein the cam interlocking portion receives the first inclined portion and then the first planar portion, according to the rotation of the rotor, and
wherein the landing member transitions between the open position and the closed position, according to the receiving by the cam interlocking portion.
14. The UAV of claim 13 , wherein:
the housing comprises a first housing having a convex disc shape and a second housing having a concave disc shape,
the first housing and the second housing comprise a plurality of comb pattern unit members spaced apart by a specific interval in a circumferential direction from respective center portions, and
the at least one landing member is configured to form a part of the plurality of comb pattern unit members.
