[0002] A drone hangar is a storage, maintenance, and management facility specifically designed for drones. With the rapid development of drone technology, as an important support platform, the drone hangar is widely used in various aspects such as the operation, management, repair, and charging of drones.

[0011] Furthermore, the middle end of the driving rod is connected to the push rod of the driving hydraulic cylinder; the parking platform includes two symmetrically distributed seventh hinge joints, two symmetrically distributed eighth hinge joints and a ninth hinge joint;

[0012] Among them, the driving rods are symmetrically arranged. One end of the driving rod is connected to the hangar shell through the second hinge joint, and the other end of the driving rod is connected to the middle end of the first connecting rod;

[0013] Among them, the parking platform is connected to the other end of the first connecting rod through the seventh hinge joint, the parking platform is connected to one end of the first limiting rod through the eighth hinge joint, and the parking platform is connected to the other end of the second connecting rod through the ninth hinge joint.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. The present invention is composed of a small number of connecting rods. The lifting and lowering of the parking platform can be achieved by adjusting the telescopic length of the hydraulic rod. The first limit rod and the second limit rod are collinear when the parking platform reaches the highest position, so that the parking platform can stably receive the UAV. The UAV hangar has the advantages of simple structure, high rigidity, strong support and adjustable parking platform height.

[0032] 2. In the present invention, the driving rod for arranging the driving hydraulic cylinder is connected to the hangar shell and the first connecting rod at the same time, so that the synchronous unfolding of the hangar shell is ensured while realizing the lifting and lowering of the parking platform, thereby realizing the rapid lifting and lowering of the UAV. At the same time, the single drive reduces the failure rate of the hangar. The hangar has the advantages of simple driving scheme and rapid deployment.

[0033] 3. The present invention mostly adopts revolute pairs at the connection of the mechanism, so that the parking platform can be raised and lowered, and the hangar shell can be expanded and folded. By controlling the length of the connecting rod and the position of the revolute pair, not only the lifting height of the parking platform can be changed, but also the opening and closing range of the hangar shell can be changed, which is better applied to the parking of various drones.

[0046] A single-drive synchronous unfolding and retracting UAV hangar provided in this embodiment is as Figure 1 、 Figure 7 shown. The single-drive synchronous unfolding and retracting UAV hangar includes a hangar housing 1, a hangar base 2, a drive rod 3, a first connecting rod 4, a parking platform 5, a drive hydraulic cylinder 6, a first limiting rod 7, a second limiting rod 8, and a second connecting rod 9. One end of the first connecting rod 4 is connected to the hangar base 2 through the hinge joint 21, and one end of the second connecting rod 9 is connected to the hangar base 2 through the hinge joint 23. At the same time, the other end of the first connecting rod 4 is connected to the parking platform 5 through the hinge joint 51, and the other end of the second connecting rod 9 is connected to the parking platform 4 through the hinge joint 53. The hangar base 2, the first connecting rod 4, the parking platform 5, and the second connecting rod 9 are connected end to end in sequence, and a parallelogram mechanism is formed by means of the hinge joint 21, the hinge joint 23, the hinge joint 51, and the hinge joint 53. The hangar housing 1 is connected to the hangar base 2 through the hinge joint 12. At the same time, the hangar housing 1 is connected to one end of the drive rod 3 through the hinge joint 11. The other end of the drive rod 3 is connected to the middle end of the first connecting rod 4. The middle of the drive rod 3 is connected to the push rod of the drive hydraulic cylinder 6. The bottom of the drive hydraulic cylinder 6 is connected to the hangar base 2 through the hinge joint 22, forming a synchronous unfolding UAV hangar as a whole.

[0047] Combined withFigure 1 As shown, the length of the driving rod 3 is less than that of the first connecting rod 4, the length of the first limiting rod 7 is less than the distance from the hinge joint 21 to the hinge joint 23 (i.e., from the hinge joint 51 to the hinge joint 53), and the length of the second limiting rod 9 is less than that of the second connecting rod 9. By adjusting the length of the driving rod 3, the opening and closing angle of the hangar shell can be changed. By adjusting the lengths of the first connecting rod 4 and the second connecting rod 9, the lifting height of the parking platform 5 can be changed. By adjusting the lengths of the first limiting rod 7 and the second limiting rod 8, the maximum lifting height of the parking platform 5 can be changed.

[0048] As Figure 1 As shown, the hangar base 2, the first connecting rod 4, the parking platform 5, and the second connecting rod 9 are connected end to end and arranged in a parallelogram, ensuring that the parking platform is always in a horizontal posture during the lifting process. The driving rod 3 is connected to the hangar shell 1 and the first connecting rod 4, ensuring that the hangar shell is synchronously unfolded and retracted while the parking platform is lifted. The driving rod 3 is connected to the driving hydraulic cylinder 6, and by controlling the telescopic movement of the hydraulic push rod of the driving hydraulic cylinder 6, the horizontal lifting of the parking platform and the unfolding and retracting of the hangar shell can be achieved synchronously.

[0049] Combined with Figure 1 、 Figure 2 As shown, when the push rod of the driving hydraulic cylinder 6 is adjusted to extend outwards, the hangar shell 2 is synchronously driven to unfold outwards and the parking platform 5 rises through the driving rod 3. During this period, the angle between the first connecting rod 4 and the hangar base 2 gradually increases, the angle between the first limiting rod 7 and the parking platform 5 gradually increases, and the angle between the hydraulic push rod of the driving hydraulic cylinder 6 and the hangar base 2 gradually decreases. When the parking platform 5 climbs to the maximum height, the first connecting rod 4 and the second connecting rod 9 are in a vertical position, the side surface of the hangar shell 1 is perpendicular to the side surface of the hangar base 2, and the first limiting rod 7 and the second limiting rod 8 are collinear, improving the load-bearing capacity of the parking platform to achieve the purpose of receiving the unmanned aerial vehicle.

[0050] Combined with Figure 1 、 Figure 3 As shown, when the push rod of the driving hydraulic cylinder 6 is adjusted to contract inwards, the hangar shell 2 is synchronously driven to fold inwards and the parking platform 5 descends through the driving rod 3. During this period, the angle between the first connecting rod 4 and the hangar base 2 gradually decreases, the angle between the first limiting rod 7 and the parking platform 5 gradually decreases, and the angle between the hydraulic push rod of the driving hydraulic cylinder 6 and the hangar base 2 gradually increases. When the limiting structure of the hangar shell contacts the limiting structure of the hangar base, the parking platform 5 descends to the lowest height, the side surface of the hangar shell 1 and the side surface of the hangar base 2 are in the same plane, and the hangar is in the smallest volume state to achieve the purpose of storing the unmanned aerial vehicle.

[0051] As Figure 4As shown in the figure, the hangar housing 1 includes a first hinge joint 11 and a second hinge joint 12. The first hinge joints 11 are symmetrically arranged. The hangar housing 1 is connected to the driving rod 3 through the first hinge joints 11. The hangar housing 1 is connected to the hangar base 2 through the second hinge joints 12, and a limiting structure is provided at the top of the hangar housing 1.

[0052] As Figure 5 shown in the figure, the hangar base 2 includes a third hinge joint 21, a fourth hinge joint 22, a fifth hinge joint 23 and a sixth hinge joint 24. The hangar base 2 is connected to the hangar housing 1 through the second hinge joints 12. The hangar base 2 is connected to one end of the first connecting rod 4 through the third hinge joint 21, and the third hinge joints 21 are symmetrically arranged on the hangar base 2. The hangar base 2 is connected to the driving hydraulic cylinder 6 through the fourth hinge joint 22. The hangar base 2 is connected to the second connecting rod 9 through the fifth hinge joint 23, and the fifth hinge joints 23 are symmetrically arranged on the hangar base 2. The hangar base 2 is connected to one end of the second limiting rod 8 through the sixth hinge joint 24, and a limiting structure is provided at the top of the hangar base 2.

[0053] As Figure 6 shown in the figure, the parking platform 5 includes two symmetrically distributed seventh hinge joints 51, eighth hinge joints 52 and two symmetrically distributed ninth hinge joints 53. The parking platform 5 is connected to the first connecting rod 4 through the seventh hinge joints 51. The parking platform 5 is connected to the first limiting rod 7 through the eighth hinge joints 52. The parking platform 5 is connected to the second connecting rod 9 through the ninth hinge joints 53.

[0054] In this embodiment, according to the change of the UAV mission, by changing the rod lengths of the connecting rod and the limiting rod to adapt to different models of UAVs, a wider range of use effects can be achieved, meeting the requirements of the designed UAV mission. The hangar has the function of synchronous movement of the parking platform lifting and the hangar housing unfolding and folding.

[0055] In an embodiment of the present invention, the operation process of the single-drive synchronous unfolding and folding UAV hangar is realized as follows:

[0056] The single-drive synchronous unfolding and folding UAV hangar of the present invention is assembled by a connecting rod, a limiting rod, a driving rod, a parking platform and a hangar housing. When the UAV has no mission requirements, it is stored in the payload compartment of the hangar, and the parking platform is in the lowest position. At this time, the overall volume of the hangar is the smallest.

[0057] In an embodiment of the present invention, the process of the single-drive synchronous unfolding and folding UAV hangar proposed by the present invention cooperating with the UAV can be divided into two stages:

[0058] During the operation of the drone hangar: the hangar base, the hangar shell, the parking platform, the driving hydraulic cylinder, the driving rod, the first connecting rod, the second connecting rod, the first limiting rod and the second limiting rod are connected according to a certain relationship. The pose of the driving rod is adjusted by the driving hydraulic cylinder to achieve the purpose of controlling the two working stages of the drone hangar.

[0059] The first stage: When the hangar reaches the working location, the hangar expands according to the task instruction of releasing the drone. The hydraulic push rod of the driving hydraulic cylinder 6 extends outwards. The driving rod 3 is connected to the hydraulic push rod, driving the hangar shell 1 and the first connecting rod 4 to move outwards and upwards. Thus, the expansion of the hangar shell 1 and the rise of the parking platform 5 are achieved simultaneously. When the expansion reaches the state where the first limiting rod 7 and the second limiting rod 8 are collinear, the first connecting rod 4 and the second connecting rod 9 are in the vertical position. The side surface of the hangar shell 1 is perpendicular to the side surface of the hangar base 2, and the parking platform reaches the maximum height. The hangar becomes a stable structure.

[0060] The second stage: When the drone is released and the drone completes the task, the hangar retracts according to the task instruction of retracting. The hydraulic push rod of the driving hydraulic cylinder 6 contracts inwards. The driving rod 3 is connected to the hydraulic push rod, driving the hangar shell 1 and the first connecting rod 4 to move inwards and downwards. Thus, the retraction of the hangar shell 1 and the descent of the parking platform 5 are achieved simultaneously. When the retraction reaches the state where the limiting structure of the hangar shell 1 contacts the limiting structure of the hangar base 2, the parking platform 5 descends to the lowest height. The side surface of the hangar shell 1 and the side surface of the hangar base 2 are in the same plane, and the hangar reaches the state with the smallest volume.

[0061] In an embodiment of the present invention, a single - drive synchronous deployment and retraction drone hangar proposed by the present invention is applicable to drones including quad - rotor drones. To achieve the smooth retraction of the drone, it is necessary to ensure that the height of the drone is not higher than the distance from the parking platform to the upper end of the hangar shell.

[0062] The above - described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
