[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, a drone receiving system is provided, such as... Figures 1 to 5 As shown, the system includes a hangar body 1, a control unit, a positioning module, a platform component 4, and a drive component. The hangar body 1 has an internal cabin and a telescopic mechanism 2. The control unit includes a control host and a motor driver, which are communicatively connected and electrically connected to the drive component. The positioning module is located on the hangar body 1 and is electrically connected to the control host. The platform component 4 is located at the telescopic end of the telescopic mechanism 2, which can drive the platform component 4 to enter and exit the cabin.

[0039] Platform component 4 serves as a landing pad. Platform component 4 includes a protective plate and a flat plate 405. At least two protective plates are provided, and the protective plates are rotatably arranged on the side of the flat plate 405. The flat plate 405 is adapted to connect with the telescopic mechanism 2. The drive component is adapted to drive the protective plate to rotate relative to the flat plate 405. Each protective plate is equipped with one or more drive components.

[0040] In this embodiment, the platform component 4 can switch between a flat state and an enclosed state. In the flat state, all protective plates and the upper part of the flat plate 405 are spliced ​​together to form a plane. In the enclosed state, all protective plates are set vertically relative to the flat plate 405, and all protective plates and the flat plate 405 are combined to form a material receiving cavity.

[0041] This solution incorporates a retractable and movable platform component 4 and a rotatable protective plate, enabling the system to switch between a flat and an enclosed state. In the flat state, the protective plate and the flat plate 405 together form a flat landing surface, facilitating safe take-off and landing of the drone. In the enclosed state, the protective plate and the material receiving cavity formed by the flat plate 405 effectively prevent materials from accidentally slipping or being damaged during delivery, significantly improving the safety and reliability of material handover. This design is suitable for fully automated operations, especially for unattended delivery scenarios.

[0042] In a specific embodiment, a flexible tilting door is rotatably provided on one side of the hangar body 1. The telescopic mechanism 2 can drive the platform assembly 4 to contact the flexible tilting door to open the entrance and exit, so that the platform assembly 4 moves to the outside of the cabin; the telescopic mechanism 2 drives the platform assembly 4 to return to the cabin, and the flexible tilting door closes the entrance and exit.

[0043] In specific embodiments, such as Figure 1 As shown, the UAV receiving system also includes two sliding supports 3, which are spaced apart, and a telescopic mechanism 2 is disposed between the two sliding supports 3; each sliding support 3 includes two sliding rods, which are slidably disposed between each other, one sliding rod is fixedly disposed in the cabin, and the other sliding rod is fixedly connected to the bottom of the flat plate 405; the telescopic mechanism 2 drives the platform assembly 4 to move in a direction parallel to the sliding direction of the two sliding rods.

[0044] This solution constructs a stable rigid motion frame by setting a telescopic mechanism 2 between two spaced sliding supports 3. Through the sliding engagement between the sliding rods, the platform component 4 is made to run smoothly in a straight line during extension and retraction, effectively preventing swaying, tilting or twisting when carrying drones and materials, and greatly enhancing motion stability. At the same time, this design helps to distribute the load from the telescopic mechanism 2 to multiple sturdy support points, optimizes the force distribution, reduces the wear of key drive components, and thus extends the mechanical life and reliability of the entire system.

[0045] In a specific embodiment, the telescopic mechanism 2 employs an electric push rod or ball screw module, which converts the rotational motion of the motor into high-precision linear motion. This facilitates easy control of stroke and speed, and provides good sealing, making it suitable for outdoor hangar environments. The telescopic mechanism 2 is connected to the control host to receive control signals and implement automated operations for extending the platform assembly 4, landing the drone, and retracting the platform. The sliding support 3 can be configured as a linear guide rail.

[0046] In some embodiments, the plate 405 is configured as a rectangular plate, and four protective plates are provided, symmetrically arranged in pairs on both sides of the plate 405 in the length and width directions; in the enclosed state, the upper surfaces of all protective plates are on the same horizontal plane. Specifically, as... Figure 3As shown, the four protective plates are designated as first protective plate 401, second protective plate 402, third protective plate 403, and fourth protective plate 404. First protective plate 401 and third protective plate 403 are symmetrically arranged on both sides of the width direction of the flat plate 405, while second protective plate 402 and fourth protective plate 404 are symmetrically arranged on both sides of the length direction of the flat plate 405. This design, by making the flat plate 405 a rectangular plate and symmetrically arranging protective plates on its four sides, forms a structurally stable and space-efficient material receiving cavity when enclosed. The symmetrical layout ensures more even stress distribution, and the upper ends of the protective plates are on the same horizontal plane, which helps enhance the structural integrity of the receiving cavity, avoids material tilting or jamming due to imbalance, and improves the overall stability and receiving success rate of the system.

[0047] In some embodiments, the protective plate and the flat plate 405 are arranged vertically or at an angle when the enclosure is in place. The vertical or angled arrangement of the protective plate in the enclosure state better covers the materials, providing lateral support, especially for items of a certain height, preventing tilting or tipping. The angled design also helps guide the materials to land in a concentrated manner, preventing items from deviating from their intended position due to bouncing or rolling, thus ensuring delivery accuracy and material safety.

[0048] In some embodiments, such as Figure 3 As shown, the drive assembly includes a rotary drive component 501 and a drive shaft 502. The rotary drive component 501 is mounted on the flat plate 405, and the drive shaft 502 is connected to the drive end of the rotary drive component 501. The drive shaft 502 is rotatably connected to the flat plate 405, and the protective plate is fixedly connected to the drive shaft 502. The drive shaft 502 is located on the side of the flat plate 405. The drive assembly, using a structure of rotary drive component 501 and drive shaft 502, achieves reliable rotation control of the protective plate. This mechanical transmission method has a fast response and accurate positioning, enabling precise control of the unfolding and retracting movements of the protective plate. It ensures the smoothness and coordination of the state switching process, avoiding damage to materials or equipment due to operational errors.

[0049] In a specific embodiment, for the drive shaft 502 and the plate 405 to be rotatably connected, a bearing or bushing may be provided at the connection point to meet the requirements of a smooth rotation design.

[0050] In some embodiments, the rotary drive 501 is configured as a motor, which is electrically connected to a motor driver. Specifically configuring the rotary drive 501 as a motor and controlling it via a motor driver enables high-precision, high-response motion control. The motor driver possesses excellent torque output and position holding capabilities, helping to maintain the stability of the protective plate under various environmental conditions, improving the overall system durability and control consistency. The motor uses a small / micro servo motor. The flipping of the protective plate requires precise angle control and sufficient torque, for example, to resist wind resistance in windy conditions. The servo motor has excellent position control capabilities and can receive PUL / DIR pulse signals through the motor driver for very precise angle control, achieving rapid and reliable switching between the flat and closed states. The control host sends a pulse signal sequence, which the motor driver converts into the motor's angular displacement and speed, thereby precisely controlling the flipping angle of the protective plate.

[0051] Specifically, taking the second protective plate 402 as an example, it is equipped with three sets of drive components. The second protective plate 402 rotates through the joint of the three sets of drive components to meet the driving requirements. Among them, the central axes of the drive shafts 502 of the three sets of drive components are arranged collinearly, and the rotation drive components 501 of the three sets of drive components are all installed at intervals on the side of the upper end face of the plate 405.

[0052] In some embodiments, such as Figure 5 As shown, the UAV receiving system also includes a communication module, which comprises a data and image transmission module and a wireless communication module. The data and image transmission module transmits data and images and communicates with the control host via a LAN network or UART. The wireless communication module communicates with the control host via a WiFi network or a 5G network. This solution, through the multiple communication methods of the data and image transmission module and the wireless communication module, enables the system to achieve stable, low-latency data interaction with the UAV and logistics backend. This facilitates the real-time issuance of control commands and status feedback, effectively enhances the system's communication reliability in complex environments, facilitates remote monitoring and scheduling of peripheral devices, and expands the system's application scope.

[0053] In a specific embodiment, the selection of the control host, the data transmission module, and the wireless communication module involves using an RK3576 processor for the control host, a 1.4G image transmission module for the data transmission module, and a wired network or WIFI / 5G communication module for the wireless communication module.

[0054] In some embodiments, the positioning module is configured as an RTK positioning module, which connects to the control host via a UART interface. This solution, employing an RTK positioning module connected to the control host via a UART interface, provides centimeter-level high-precision positioning support for the UAV, significantly improving positioning accuracy during the landing phase. It can be combined with onboard visual recognition, such as QR code positioning, to enhance the landing accuracy and reliability of the UAV, reducing the risk of deployment errors or aircraft collisions due to positioning deviations. QR codes are affixed to the hangar itself to allow the UAV to use its onboard camera for visual-assisted positioning and landing.

[0055] The UAV receiving system provided in this embodiment, such as Figure 4 As shown, its working principle is as follows:

[0056] After the drone lands, the backend sends PWM / DIR signals to the motor driver through the control host;

[0057] The motor driver drives the motor via the motor signal PUL / DIR to retract the guardrail;

[0058] After the drone safely delivers the object, the backend sends PWM / DIR signals to the motor driver through the control host;

[0059] The motor driver drives the motor via the motor signal PUL / DIR to achieve the flattening of the guardrail;

[0060] The drone departed safely, provided the tarmac was level.

[0061] Explanation of the receiving process:

[0062] The delivery process is handled in the logistics backend: After receiving instructions at the designated location, the drone uses RTK positioning to navigate to the receiving hangar along a predetermined route; when the drone carrying the item approaches the hangar, the backend sends a command to open the receiving compartment; a QR code is affixed to the receiving compartment's landing pad, and when the drone docks above the hangar, its camera algorithm provides precise positioning for accurate landing; after the drone docks (or hovers), the backend automatically retracts the protective barrier before sending a command to drop the item, ensuring its safety; after item drop, the logistics backend first instructs the protective barrier to be lowered, then the drone departs and the receiving compartment is closed; once the process is complete, the logistics backend sends a text message to the recipient.

[0063] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
