Unmanned aerial vehicle system including foldable unmanned aerial vehicle
An unmanned aerial vehicle system includes an unmanned aerial vehicle (UAV) and a ground station. The UAV folds from a first position in which the UAV defines a first expanse for flying to a second position in which the UAV defines a second expanse that is smaller than the first expanse for facilitating storage of the UAV. The ground station includes a box assembly and a landing pad assembly. The box assembly defines a storage cavity for storing the UAV when the UAV is disposed in the second position. The first expanse is larger than the storage cavity can accommodate. The landing pad assembly is movably coupled to the box assembly. The landing pad assembly is movable in a first direction to cause the UAV to fold into the storage cavity for storing the unmanned aerial vehicle within the box assembly.
1 . An unmanned aerial vehicle system, comprising:
an unmanned aerial vehicle configured to fold from a first position in which the unmanned aerial vehicle defines a first expanse for flying to a second position in which the unmanned aerial vehicle defines a second expanse that is smaller than the first expanse for facilitating storage of the unmanned aerial vehicle; and
a ground station including:
a box assembly defining a storage cavity configured to store the unmanned aerial vehicle when the unmanned aerial vehicle is disposed in the second position, the first expanse of the unmanned aerial vehicle being larger than the storage cavity can accommodate; and
a landing pad assembly movably coupled to the box assembly, the landing pad assembly being movable in a first direction to cause the unmanned aerial vehicle to fold into the storage cavity for storing the unmanned aerial vehicle within the box assembly.
2 . The unmanned aerial vehicle system of claim 1 , wherein the landing assembly is movable in a second direction to cause the unmanned aerial vehicle to unfold from the second position to the first position for enabling the unmanned aerial vehicle to deploy from the landing pad assembly.
3 . The unmanned aerial vehicle system of claim 1 , wherein the landing pad assembly is autonomously actuatable to cause the landing pad assembly to move relative to the box assembly.
4 . The unmanned aerial vehicle system of claim 1 , wherein the unmanned aerial vehicle includes a body defining a longitudinal axis, wings extending from the body in a direction transverse to the longitudinal axis of the body, a tail assembly disposed proximal to the body, and rotor assemblies coupled to the wings.
5 . The unmanned aerial vehicle system of claim 4 , wherein each rotor assembly includes a vertical rotor assembly having at least two propellers.
6 . The unmanned aerial vehicle system of claim 4 , wherein at least one of the wings is foldable toward and away from the longitudinal axis of the body in response to movement of the landing pad assembly.
7 . The unmanned aerial vehicle system of claim 4 , wherein the tail assembly is moveable along the longitudinal axis of the body in response to movement of the landing pad assembly.
8 . The unmanned aerial vehicle system of claim 5 , wherein at least one of the at least two propellers is movable toward the other of the at least two propellers in response to movement of the landing pad assembly to change an angular distance between the at least two propellers.
9 . The unmanned aerial vehicle system of claim 5 , wherein in response to movement of the landing pad assembly:
at least one of the wings is foldable toward and away from the longitudinal axis of the body,
the tail assembly is moveable along the longitudinal axis of the body, and/or
at least one of the at least two propellers is movable toward the other of the at least two propellers to change an angular distance between the at least two propellers.
10 . The unmanned aerial vehicle system of claim 9 , wherein the at least one wing includes a spring assembly that urges the at least one wing away from the longitudinal axis of the body.
11 . The unmanned aerial vehicle system of claim 9 , wherein the tail assembly includes a first arm assembly, a second arm assembly, and a tail the connects the first arm assembly to the second arm assembly.
12 . The unmanned aerial vehicle system of claim 11 , wherein the first arm assembly and the second arm assembly each include a fixed portion and a movable portion that is pivotably coupled to the fixed portion.
13 . The unmanned aerial vehicle system of claim 12 , wherein the fixed portion is pinned to the movable portion.
14 . The unmanned aerial vehicle system of claim 4 , wherein the body includes a propeller that rotates about the longitudinal axis of the body.
15 . The unmanned aerial vehicle system of claim 1 , wherein the grounding station further includes doors that are pivotably coupled to the box assembly, the doors moveable between open and closed position.
16 . The unmanned aerial vehicle system of claim 15 , wherein the ground station is configured to enclose the unmanned aerial vehicle within the storage cavity when the doors are disposed in the closed position.
17 . The unmanned aerial vehicle system of claim 4 , wherein at least one of the wings includes a movable portion and a fixed portion, the fixed portion coupled to the body, the movable portion coupled to the fixed portion.
18 . The unmanned aerial vehicle system of claim 17 , wherein the movable portion is foldable relative to the fixed portion and toward and away from the longitudinal axis of the body.
19 . The unmanned aerial vehicle system of claim 18 , wherein a spring assembly couples the movable portion to the fixed portion to urge the movable portion away from the longitudinal axis of the body.
20 . The unmanned aerial vehicle system of claim 19 , wherein the spring assembly includes a torsion spring.
