Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) storage and retrieval equipment technology, and particularly to UAV automated hangars. Background Technology

[0002] With the rapid development of drone technology, its applications in aerial surveying, logistics, power line inspection, and emergency rescue are becoming increasingly widespread. The number of drones used and the frequency of their operations have increased significantly, placing higher demands on drone storage, maintenance, and management equipment. As the core facility for drone storage and support, the performance of hangars directly affects drone operational efficiency, equipment safety, and maintenance costs.

[0003] Chinese Patent Publication No. CN112706938B discloses a multi-drone three-dimensional hangar. The first frame houses a liftable drone attitude adjustment device, and the second frame contains several layers of parking platforms. The drone attitude adjustment device includes adjustment plates with left and right support assemblies fixedly mounted on their bottom sides. The left and right support assemblies are connected to tilt drive devices, which control the tilt direction and value of the adjustment plates. A centering device is provided on the upper surface of the adjustment plates, enabling the drone to move within the plane of the adjustment plate. Alignment is achieved in both the X and Y axes. The alignment device is connected to the telescopic transmission device, which drives the alignment device to reciprocate above the adjustment plate and the parking plate. This hangar can provide a horizontal parking platform for drones in the overall tilted state of the drone hangar, and place the aligned drone into the empty parking plate and fix it. However, in actual use, the receiving and transfer processes of this hangar cannot be carried out in parallel. When multiple drones return in succession, it is necessary to wait for the previous drone to complete the storage process before the next drone can be received, resulting in low operation efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide a three-dimensional hangar for unmanned aerial vehicles (UAVs), which can effectively solve the problem that the receiving and transfer processes cannot be carried out in parallel.

[0008] Preferably, the placement mechanism includes a placement plate, which is fixedly installed on the upper part of the outer surface of the transmission component. The placement plate has mounting grooves on both sides of its middle section. Conveying components are provided at the middle and both sides of the upper end of the placement plate. Gear sets are provided at the middle of both sides of the placement plate. On the side of the two gear sets that are far apart from each other, racks are fixedly installed on the upper end of the limiting frame. The two gear sets are respectively meshed with the two racks.

[0009] Preferably, the picking mechanism includes a picking handle, which is slidably installed in the inner cavity of the mounting groove. A rack is provided on one side of the outer surface of the picking handle, and the rack is meshed with a gear set. An elastic hydraulic telescopic rod is provided on the other side of the outer surface of the picking handle. A fixing member is provided on the side of the inner cavity of the picking handle near the conveying device.

[0010] Preferably, the fixing component includes a fixing plate, which is slidably installed in the inner cavity of the handle. One side of the outer surface of the fixing plate is fixedly connected to the protruding end of the second elastic hydraulic telescopic rod. Fixing frames are provided on both sides of the upper end of the fixing plate. An oil supply pipe is provided in the middle of the two fixing frames. Fixing claws that are slidably installed on the outer surface of the oil supply pipe are provided on both sides of the middle of the two fixing frames. Hydraulic telescopic rods are provided on both sides of the inner cavity of the two fixing frames. The protruding ends of the four hydraulic telescopic rods are respectively fixedly connected to the outer surfaces of the four fixing claws.

[0011] Preferably, the driven mechanism includes a hydraulic chamber, which is fixedly installed in the middle of the inner cavity of the limiting frame. The inner cavity of the hydraulic chamber is connected to the inner cavity of the second elastic hydraulic telescopic rod through a hydraulic pipe. A driven rod is provided in the middle of the hydraulic chamber. A piston is slidably installed in the inner cavity of the hydraulic chamber on one end face of the driven rod. A connecting rod is provided in the middle of the driven rod. A spring is provided between one end face of the connecting rod and the bottom wall of the inner cavity of the driven rod.

[0012] Preferably, the braking component includes a hydraulic cylinder, which is fixedly installed on the bottom wall of the inner cavity of the limiting frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the containers on the upper and lower sides of the conveying device can work alternately and cyclically. When the container carrying the drone is conveyed into the inner cavity of the protective frame, the lower container is simultaneously conveyed to the upper working position, which can continuously receive the drones that land subsequently. This avoids the waiting time of single-station reception in traditional hangars and significantly improves the efficiency of drone reception and storage.

[0015] In this invention, the limiting groove one of the holding component and the limiting groove two of the storage plate provide guiding limits for the drone's receiving and storage, respectively. The fixing component of the picking mechanism clamps the drone's landing gear through hydraulically driven fixing claws, ensuring that the drone does not shake or shift during the transfer process, and avoiding equipment collision damage caused by unstable fixing.

[0016] In this invention, after completing its operation, the drone can autonomously navigate and land on the conveying device. Subsequent transfer, storage, and retrieval processes are all completed by drive mechanisms such as motors and hydraulic cylinders, eliminating the need for manual operation. The entire process is fully automated, which not only reduces labor costs but also avoids errors and safety hazards that may be caused by manual operation, thereby improving the operational efficiency of the hangar.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, this embodiment discloses an automated hangar for unmanned aerial vehicles (UAVs), including a base plate 1. A protective frame 2 is provided on the upper end of the base plate 1. A protective plate for protection is provided on the surface of the protective frame 2. An alarm 3 is provided on the upper end of the protective frame 2. A conveying device 4 is provided on one side of the upper end of the base plate 1. One end of the conveying device 4 extends to the outside of the protective frame 2. A storage cabinet 7 is provided on the other side of the upper end of the base plate 1. A lifting device 5 is provided in the middle of the upper end of the base plate 1. A placement device 6 is provided in the middle of the outer surface of the lifting device 5.

[0022] Specifically, after the drone completes its operation, it flies autonomously to the top of the drone hangar and gradually lands on the upper part of the conveyor device 4. Then the conveyor device 4 is activated, which moves the drone into the inner cavity of the protective frame 2. When the drone reaches the designated position, the placement device 6 lifts it from the upper part of the conveyor device 4 and finally transfers it to the inner cavity of the storage cabinet 7 for storage.

[0023] Furthermore, when it is necessary to retrieve the drone from the inner cavity of the storage cabinet 7, the lifting device 5 drives the placement device 6 to rise and fall to the corresponding storage position. The placement device 6 lifts the drone in the corresponding position in the storage cabinet 7 upwards. Then, with the coordinated action of the lifting device 5 and the placement device 6, the drone is transferred to the upper part of the conveying device 4. The conveying device 4 starts to transport the drone out of the inner cavity of the protective frame 2, at which point the drone can start to take off.

[0024] Furthermore, in this invention, the protective frame 2 and the protective plate provide a closed storage environment for the drone, which can effectively resist the influence of external natural factors such as wind, rain, and dust. The alarm 3 at the top of the protective frame can promptly issue an alarm when abnormal situations occur in the hangar, such as equipment failure or illegal intrusion, thereby enhancing the security performance of the hangar and ensuring the storage safety of the drone.

[0025] To achieve efficient receiving and continuous storage operations by drones, such as Figure 3 As shown, the conveying device 4 includes a mounting frame 41, which is fixedly mounted on the upper end of the base plate 1. Two transmission wheel sets 42 are provided on both sides of the inner cavity of the mounting frame 41. Two transmission belts 43 are provided on the outer surface of the two transmission wheel sets 42. Two holding parts 44 are provided on the upper and lower sides of the outer surface of the two transmission belts 43. A motor 45 for providing power to the transmission wheel sets 42 is provided on the outer surface of the mounting frame 41 near the lifting device 5.

[0026] Furthermore, such as Figure 4 As shown, the container 44 includes a container plate 441, which is fixedly installed on the outer surface of the transmission belt 43. Limiting grooves 442 are provided on both sides of the middle part of the outer surface of the container plate 441.

[0027] Specifically, after the drone flies to the top of the hangar, it lands on the upper part of the container 44 on the side away from the placement device 6 in the upper part of the conveying device 4. The motor 45 starts and drives multiple sets of transmission wheel sets 42 to rotate. Through the transmission belt 43, the container 44 carrying the drone is transported to the inner cavity of the protective frame 2. At the same time, the container 44 located at the lower part of the transmission belt 43 is synchronously transferred to the upper working position, which can realize the continuous reception of subsequent drones.

[0028] Example 2

[0029] This embodiment further improves the placement device 6 based on Embodiment 1. To transport the drone that lands on the conveyor device 4 to the inner cavity of the storage cabinet 7 for storage, as follows... Figure 5 - Figure 7 As shown, the placement device 6 includes a limiting frame 61, which is slidably mounted on the outer surface of the lifting device 5. One side of the outer surface of the limiting frame 61 is fixedly connected to the lifting component of the lifting device 5. A motor 62 is provided at the lower end of the limiting frame 61, and a transmission component 63 is provided in the middle of the limiting frame 61. The extended end of the motor 62 is connected to one side of the outer surface of the transmission component 63 through a belt transmission mechanism. A placement mechanism 64 is provided at the upper end of the transmission component 63. Picking mechanisms 65 are provided on both sides of the middle of the placement mechanism 64. The two picking mechanisms 65 are adapted to the holding plate 441. A driven mechanism 66 is provided in the middle of the inner cavity of the limiting frame 61, and a brake component 67 is provided in the middle of the bottom wall of the inner cavity of the limiting frame 61.

[0030] Specifically, when the conveying device 4 moves the drone into the inner cavity of the protective frame 2 to the designated position, the second motor 62 starts to drive the transmission component 63 to move. The transmission component 63 drives the placement mechanism 64 to move towards the side closer to the conveying device 4. During this process, the two sets of picking mechanisms 65 extend synchronously and insert into the inner cavities of the two sets of limiting slots 442 respectively. When the placement mechanism 64 reaches the lifting position, the lifting device 5 drives the entire placement device 6 to rise and fall upward through the limiting frame 61, so that the two sets of picking mechanisms 65 lift the drone away from the conveying device 4. Then the brake component 67 is activated, driving the fixing component in the picking mechanism 65 to lock and fix the drone. After the fixing is completed, the second motor 62 rotates in the opposite direction, driving the placement mechanism 64 to move towards the side closer to the storage cabinet 7.

[0031] Furthermore, when the placement mechanism 64 moves to one side of the storage cabinet 7, the retrieval mechanism 65 retracts and then extends under the drive of the placement mechanism 64. At the same time, the placement mechanism 64 contacts the driven mechanism 66, and the driven mechanism 66 drives the corresponding component in the retrieval mechanism 65 to move, pushing the drone located on the upper end of the retrieval mechanism 65 near the conveying device 4 to the other side of the upper end. During this process, the lifting device 5 drives the placement device 6 to rise and fall in the vertical direction, so that the drone reaches the corresponding height of the idle placement platform of the storage cabinet 7. Finally, the placement device 64 moves to put the drone into the inner cavity of the storage cabinet 7 to complete the storage.

[0032] To drive the movement of the picking mechanism 65, and to facilitate the movement of the picking mechanism 65 by the drone, such as... Figure 8 As shown, the placement mechanism 64 includes a placement plate 641, which is fixedly installed on the upper part of the outer surface of the transmission member 63. The middle part of the placement plate 641 has mounting grooves 645 on both sides. The upper middle part and both sides of the placement plate 641 are provided with conveying members 642. The middle parts of both sides of the placement plate 641 are provided with gear sets 643. The two gear sets 643 are respectively provided with racks 644 fixedly installed on the upper end of the limit frame 61 on the side that is far away from each other. The two gear sets 643 are respectively meshed with the two racks 644.

[0033] Specifically, when motor 2 62 drives the placement plate 641 to move horizontally through transmission component 63, the gear sets 643 on both sides rotate under the meshing action of rack 1 644, thereby driving the two sets of picking mechanisms 65 to move synchronously through gear transmission.

[0034] Furthermore, the gear set 643 consists of three meshing gears, including a large gear and two small gears, wherein the large gear meshes with the rack 644, and the small gears near the mounting slot 645 mesh with the corresponding picking mechanism 65.

[0035] Furthermore, the upper part of the conveyor 642 is provided with multiple sets of long strip-shaped conveyor wheels, and the upper part of the conveyor wheels is flush with the upper end of the picking mechanism 65. When the picking mechanism 65 pushes the drone to move from one side of the upper end to the other side, the conveyor 642 can assist the drone in moving and at the same time support the drone body to ensure the stability of the transfer process.

[0036] In order to transport the drones that have landed on the conveyor 4 into the interior of the storage cabinet 7 for storage, such as Figure 9 As shown, the picking mechanism 65 includes a picking handle 651, which is slidably installed in the inner cavity of the mounting groove 645. A rack 652 is provided on one side of the outer surface of the picking handle 651, which meshes with the gear set 643. An elastic hydraulic telescopic rod 654 is provided on the other side of the outer surface of the picking handle 651. A fixing member 653 is provided on the side of the inner cavity of the picking handle 651 near the conveying device 4.

[0037] Specifically, when the placement plate 641 is translated, the gear set 643 rotates under the action of rack 1 644, and drives the pick-up handle 651 to slide in the inner cavity of the mounting groove 645 through the meshing transmission of rack 2 652.

[0038] Furthermore, when the placement mechanism 64 moves to the lifting position near the conveying device 4, the lifting device 5 drives the placement device 6 to rise and fall. The two sets of handles 651 lift the drone away from the conveying device 4. Then, the brake 67 activates the drive fixing component 653 to lock and fix the drone landing gear. After fixing, the placement mechanism 64 moves horizontally towards the storage cabinet 7. During this process, the placement plate 641 contacts the driven mechanism 66 and drives it to move, causing the hydraulic oil in the inner cavity of the driven mechanism 66 to be injected into the inner cavity of the two sets of elastic hydraulic telescopic rods 654. The elastic hydraulic telescopic rods 654 extend and push the two sets of fixing components 653 to move towards the storage cabinet 7, finally transferring the drone into the inner cavity of the storage cabinet 7 for storage.

[0039] Furthermore, when retrieving the drone from the inner cavity of the storage cabinet 7, the fixing member 653 is positioned closer to the storage cabinet 7 under the action of the driven mechanism 66. After the retrieval mechanism 65 lifts the drone, the braking member 67 also drives the fixing member 653 to fix the drone landing gear. When the placement mechanism 64 moves towards the side closer to the conveying device 4, the spring 2 in the inner cavity of the elastic hydraulic telescopic rod 2 654 resets, causing the fixing member 653 to move towards the side closer to the conveying device 4. At the same time, the hydraulic oil in the inner cavity of the elastic hydraulic telescopic rod 2 654 flows back to the inner cavity of the driven mechanism 66.

[0040] In order to fix the drone, such as Figure 11 As shown, the fixing member 653 includes a fixing plate 6531, which is slidably installed in the inner cavity of the handle 651. One side of the outer surface of the fixing plate 6531 is fixedly connected to the protruding end of the second elastic hydraulic telescopic rod 654. Fixing frames 6532 are provided on both sides of the upper end of the fixing plate 6531. An oil pipe 6533 is provided in the middle of the two fixing frames 6532. Fixing claws 6534 are slidably installed on the outer surface of the oil pipe 6533 on both sides of the middle of the two fixing frames 6532. A hydraulic telescopic rod 6535 is provided on both sides of the inner cavity of the two fixing frames 6532. The protruding ends of the four hydraulic telescopic rods 6535 are respectively fixedly connected to the outer surfaces of the four fixing claws 6534.

[0041] Specifically, after the lifting mechanism 65 lifts the drone into place, the braking component 67 is activated, and hydraulic oil is drawn from the inner cavity of the hydraulic telescopic rods 6535 on both sides through the oil supply pipe 6533. At this time, the two sets of fixing claws 6534 in the middle of the fixing frame 6532 move towards each other under the action of hydraulic differential, thereby clamping and fixing the drone landing gear.

[0042] Furthermore, when the elastic hydraulic telescopic rod 654 extends or retracts, the entire fixing component 653 slides within the cavity of the handle 651 via the fixing plate 6531, thereby enabling the drone to be moved and transported horizontally.

[0043] To drive the elastic hydraulic telescopic rod 2654 to move, such as Figure 10 As shown, the driven mechanism 66 includes a hydraulic chamber 661, which is fixedly installed in the middle of the inner cavity of the limiting frame 61. The inner cavity of the hydraulic chamber 661 is connected to the inner cavity of the elastic hydraulic telescopic rod 654 through a hydraulic pipe. A driven rod 662 is provided in the middle of the hydraulic chamber 661. A piston that is slidably installed in the inner cavity of the hydraulic chamber 661 is provided on one end face of the driven rod 662. A connecting rod 663 is provided in the middle of the driven rod 662. A spring 664 is provided between one end face of the connecting rod 663 and the bottom wall of the inner cavity of the driven rod 662. A connecting plate is provided on the other end face of the connecting rod 663. The connecting plate is adapted to the limiting frame 61.

[0044] Specifically, when the placement mechanism 64 moves to a preset distance closer to the storage cabinet 7, the surface of the placement plate 641 contacts the connecting plate at one end of the connecting rod 663. As the placement plate 641 continues to move to the storage cabinet 7, the connecting rod 663 pulls the driven rod 662 to move synchronously under the elastic force of the spring 664. The driven rod 662 drives the piston to slide in the inner cavity of the hydraulic chamber 661, pressing the hydraulic oil in the inner cavity of the hydraulic chamber 661 into the inner cavity of the elastic hydraulic telescopic rod 654, driving it to extend.

[0045] Furthermore, although spring 664 is fixed between connecting rod 663 and driven rod 662, it does not undergo tensile deformation under normal operating conditions. This design is to prevent the fixing member 653 from sliding from one side of the cavity of the handle 651 to the other side when the translational stroke of the placement mechanism 64 is too long. At this time, the connecting rod 663 can extend out from the cavity of the driven rod 662, and spring 664 stretches and deforms to compensate for the excess stroke and prevent the mechanism from jamming.

[0046] In order to drive the fixed part 653 to move, such as Figure 12 As shown, the braking component 67 includes a hydraulic cylinder 671, which is fixedly installed on the bottom wall of the inner cavity of the limiting frame 61. The extended end of the hydraulic cylinder 671 is provided with a hydraulic component 672, and the inner cavity of the hydraulic component 672 communicates with the inner cavity of the oil supply pipe 6533 in the two fixing components 653.

[0047] Specifically, when it is necessary to fix the drone landing gear, the hydraulic cylinder 671 is activated, pulling the piston in the inner cavity of the hydraulic component 672. The hydraulic oil in the inner cavity of the two hydraulic telescopic rods 6535 is drawn into the inner cavity of the hydraulic component 672 through the oil supply pipe 6533. The two sets of fixing claws 6534 move towards each other under the action of hydraulic pressure, thereby clamping and fixing the drone landing gear.

[0048] To achieve tiered storage for drones, such as Figure 13 As shown, the storage cabinet 7 includes a storage frame 71, which is fixedly installed on the upper end of the base plate 1. Multiple mounting platforms 72 are provided in the middle of the inner cavity of the storage frame 71. A storage plate 73 is provided on the upper end of each mounting platform 72. Limiting grooves 731 are provided on both sides of the upper end of the storage plate 73. The limiting grooves 731 are adapted to the retrieval mechanism 65.

[0049] Specifically, when storing a drone, the retrieval mechanism 65 first extends into the empty storage space of the storage cabinet 7, the lifting device 5 drives the placement device 6 to move down and up, and the retrieval mechanism 65 gradually inserts into the inner cavity of the limiting groove 731 until the drone landing gear contacts the upper end of the storage plate 73. At this time, the fixing part 653 releases the fixing state of the drone, and the placement mechanism 64 moves horizontally towards the side closer to the conveying device 4 until the retrieval mechanism 65 is completely removed from the inner cavity of the storage cabinet 7, and the storage operation is completed.

[0050] Furthermore, when retrieving the drone from the inner cavity of the storage cabinet 7, the retrieval mechanism 65 first inserts into the inner cavity of the corresponding limiting groove 731, the lifting device 5 drives the placement device 6 to rise and fall, and the retrieval mechanism 65 lifts the drone away from the storage plate 73, and then proceeds with the subsequent transfer process.

[0051] Furthermore, a charging station is provided at the upper center of the storage plate 73 to charge the drone. This is existing technology and will not be described in detail in this manual.

[0052] It should be noted that the specific installation methods, circuit layout and connection methods of the alarm device 3, lifting device 5 and motor 45 used in the above embodiment 1 and the motor 62 and hydraulic cylinder 671 used in embodiment 2, as well as their control methods, are all conventional designs in the prior art, and will not be described in detail in this invention.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
