[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] like Figures 1-7 As shown, the intelligent drone landing pad in this embodiment includes a box 1 with an open top. The box 1 provides a closed storage space for the drone, effectively preventing damage from external wind, rain, dust, and debris. A folding door 2 is installed at the top edge of the box 1. The folding door 2 adopts an electric folding structure to open and close the top opening of the box 1. When open, it facilitates the landing and takeoff of the drone, and when closed, it provides protection for the drone inside the box.

[0021] The housing 1 contains a support plate 3, which is horizontally arranged to support the drone to be parked. Its size is adapted to the body size of mainstream drones and can be adjusted according to the specific drone model. The housing 1 consists of a support frame 4, a base plate 6, and a protective plate 7. The support frame 4 is the core load-bearing structure of the housing 1, which is assembled from multiple spliced ​​profiles 5 by connectors. Adjacent spliced ​​profiles 5 are detachably fixedly connected by connectors, which facilitates disassembly and storage during transportation, reduces transportation costs, and facilitates rapid on-site assembly and subsequent maintenance and replacement.

[0022] A base plate 6 is fixedly installed at the bottom of the support frame 4. The base plate 6 is made of high-strength alloy plate and is used to close the bottom of the support frame 4, while providing an installation base for components such as the lifting mechanism. Protective plates 7 are fixedly installed around the support frame 4. The protective plates 7 are made of waterproof and corrosion-resistant transparent plate, which can effectively block the external environment from corroding the internal components of the box and facilitate observation of the internal situation.

[0023] The support plate 3 is equipped with a locking mechanism and a recovery device. The locking mechanism is used to securely fix the drone to the support plate 3 to prevent the drone from shifting. The recovery device is used to automatically retract the drone's rotor without manual intervention. The support frame 4 is equipped with a lifting mechanism, which is connected to the support plate 3. The lifting mechanism is used to drive the support plate 3 and the fixed drone to move up and down longitudinally (i.e., in the height direction of the box 1) to realize the storage and retrieval of the drone.

[0024] The locking mechanism is used to limit and fix the drone's legs from both sides. Combined with subsequent electromagnet-based fixation, this forms a double-fixation structure, ensuring reliable fixation. The locking mechanism includes two symmetrically distributed limiting rods 8. The positions of the two limiting rods 8 correspond to the positions of the drone's left and right legs, allowing them to clamp and limit the drone's legs from both sides. Alternatively, limiting rods 8 can be installed at the front and rear ends to limit the drone's front and rear ends, or they can be placed at all four sides of the drone. The specific distribution can be selected based on the drone model.

[0025] Each of the limiting rods 8 has a slider 9 fixedly mounted on its side wall. The two sliders 9 are arranged symmetrically, and a synchronous belt 10 is provided below the two sliders 9. The two sides of the synchronous belt 10 are fixedly connected to the two sliders 9 respectively. One end of the synchronous belt 10 is connected to a servo motor 11, which is fixedly mounted on the lower surface of the support plate 3 to provide power for the movement of the limiting rods 8. By operating the synchronous belt 10, the two limiting plates 8 can be moved relative to each other, thereby abutting against the drone legs to fix and limit the drone. To ensure the safety of the sliders 9 and To ensure the smoothness and guidance of the movement of the limiting rod 8, the support plate 3 is provided with a sliding groove 12 that works with the slider 9. The sliding groove 12 extends horizontally, and the slider 9 is slidably embedded in the sliding groove 12 and can slide horizontally along the sliding groove 12. The lower surface of the support plate 3 is also fixedly provided with a sliding guide rail 13 that works with the slider 9. The sliding guide rail 13 is arranged parallel to the sliding groove 12, and the slider 9 is slidably connected to the sliding guide rail 13. Through the dual guiding effect of the sliding groove 12 and the sliding guide rail 13, the slider 9 can be effectively prevented from deviating or getting stuck during movement.

[0026] An electromagnet 14 is fixedly installed on the upper surface of the support plate 3. The position of the electromagnet 14 corresponds to the position of the drone's legs, and each leg is equipped with at least one electromagnet 14. When the drone lands on the support plate 3 and the legs are in the designated position, the electromagnet 14 is energized to generate magnetic force, which attracts and fixes the drone's legs, completing the pre-positioning of the drone's landing and making the drone land in a fixed area. This facilitates the limiting rod 8 to limit and fix the drone. After the limiting rod 8 locks the drone, the electromagnet 14 can continue to work to assist in locking, or the electromagnet 14 can be turned off, and only the limiting rod 8 is used for locking and limiting.

[0027] The recovery device is used to automatically retract the drone rotor. It includes a cross brace 15, a servo motor 16, a connecting rod 17, a push pin 18, a telescopic push rod 19, and a lifting guide rod 20. The components work together to achieve precise and efficient retraction of the drone rotor. The cross brace 15 is a long strip structure made of lightweight alloy material. The servo motor 16 is fixedly mounted on the top of the cross brace 15. The output end of the servo motor 16 is fixedly connected to the connecting rod 17 through a coupling. The end of the connecting rod 17 away from the servo motor 16 is fixedly equipped with a push pin 18. The push pin 18 is made of flexible and wear-resistant material to avoid scratching or damaging the rotor during the pushing process. The function of the push pin 18 is to push the drone rotor, so that the rotor slowly retracts to the designated position under the force of the push pin 18. The recovery device replaces manual operation and also minimizes the size of the overall equipment, making the whole device more compact, easy to carry, and suitable for more operating environments.

[0028] In this embodiment, the number of cross braces 15 is set to two. The two cross braces 15 are horizontally fixed at both ends of the support plate 3, and the two cross braces 15 are arranged in parallel. Each of the two ends of the cross brace 15 is fixedly equipped with a servo motor 16, that is, the two cross braces 15 are equipped with a total of four servo motors 16. The four servo motors 16 are respectively set to correspond to the four rotors of the UAV, and can simultaneously perform the retraction operation of the four rotors of the UAV. Compared with the single-side or single retraction method, it greatly improves the efficiency and synchronization of rotor retraction, and ensures that the retraction angle of the four rotors is consistent and the attitude is stable.

[0029] To adapt to the rotor height of different drone models and ensure that the ejector pin 18 can accurately push the rotor, a telescopic push rod 19 is fixedly connected to the lower part of the cross brace 15. The telescopic push rod 19 adopts an electric telescopic structure, and its fixed end is mounted on the support plate 3 through a bracket. The telescopic end of the telescopic push rod 19 is fixedly connected to the lower surface of the cross brace 15. Lifting guide rods 20 are symmetrically arranged on both sides of the telescopic push rod 19. The lifting guide rod 20 has a cylindrical structure, one end of which is fixedly connected to the lower surface of the cross brace 15, and the other end slides through the support plate 3. A guide sleeve (not shown in the figure) is provided at the penetration point between the lifting guide rod 20 and the support plate 3 to reduce the friction during the sliding process of the lifting guide rod 20.

[0030] During operation, the telescopic push rod 19 can drive the cross brace 15 to move longitudinally up and down along the lifting guide rod 20, thereby adjusting the height of the ejector pin 18 so that the ejector pin 18 is accurately aligned with the rotor position of the UAV, meeting the folding requirements of UAVs of different models and rotor heights, and improving the versatility of the device.

[0031] The lifting mechanism is used to drive the support plate 3 and the drone fixed on the support plate 3 to move vertically up and down, so as to realize the storage (lowering into the box 1) and removal (rising to the top opening of the box 1) of the drone. The lifting mechanism includes a lifting platform 21, threaded rods 22, guide columns 23, and a synchronous drive source. The lifting platform 21 is a block structure, and there are two of them, which are fixedly installed on both sides of the bottom of the support plate 3, forming an integrated structure with the support plate 3. Threaded rods 22 are rotatably arranged on both sides of the support frame 4 corresponding to the positions of the lifting platform 21. The threaded rods 22 are arranged longitudinally (in the height direction of the housing 1). The lifting platform 21 has threaded holes that cooperate with the threaded rods 22. The lifting platform 21 is threadedly fitted onto the threaded rods 22 through the threaded holes. When the threaded rods 22 rotate, they can drive the lifting platform 21 to move longitudinally along the threaded rods 22. To prevent the lifting platform 21 from rotating or deviating during movement and to ensure lifting stability, guide columns 23 are arranged parallel to both sides of the threaded rods 22. The guide columns 23 are fixedly installed on the support frame 4 longitudinally. The lifting platform 21 has guide holes that cooperate with the guide columns 23. The lifting platform 21 is slidably fitted onto the guide columns 23 through the guide holes. The guide columns 23 provide guidance for the movement of the lifting platform 21.

[0032] A synchronous drive source is installed below the support plate 3 to drive the two threaded rods 22 to rotate synchronously, ensuring that the lifting platforms 21 on both sides rise and fall synchronously, thereby ensuring that the support plate 3 rises and falls horizontally and preventing the drone from tilting or tipping over due to asynchronous lifting on both sides. The synchronous drive source includes a drive motor 24, a drive wheel 25, a driven wheel 26, and a transmission belt 27. The drive motor 24 is fixedly installed in the lower middle part of the support plate 3, and the output end of the drive motor 24 is fixedly connected to the drive wheel 25 through a coupling. A driven wheel 26 is fixedly fitted on the lower part of each threaded rod 22. The drive wheel 25 and the two driven wheels 26 are triangularly distributed and connected to each other through the transmission belt 27. The transmission belt 27 is a high-strength synchronous belt to ensure the stability and synchronicity of the transmission.

[0033] The support frame 4 is made up of multiple splicing profiles 5 spliced ​​together by connectors. In order to reduce the overall weight of the support frame 4 and facilitate wiring and installation of other components, a through groove 28 is provided in the middle of the splicing profile 5 along its length. The through groove 28 passes through both ends of the splicing profile 5. When wiring, wires, signal lines, etc. can be run through the through groove 28 to avoid the lines being exposed and damaged, and at the same time make the overall structure neater.

[0034] The connector uses angle iron 29, which has a right-angle structure and mounting holes on both right-angled sides. The ends of two adjacent splicing profiles 5 (usually arranged vertically) are fixedly connected via angle iron 29. Specifically, the two right-angled sides of angle iron 29 are respectively attached to the sidewalls of the two adjacent splicing profiles 5. Bolts pass through the mounting holes of angle iron 29 and are embedded in the through grooves 28 of the splicing profiles 5. The bolts are then tightened with nuts, achieving a stable connection between the adjacent splicing profiles 5. This connection method is convenient for assembly and disassembly; only the bolts need to be removed to separate the splicing profiles 5, facilitating transportation and on-site assembly. Simultaneously, the connection strength is high, ensuring the load-bearing stability of the support frame 4. Operating principle: Step 1, Preparation Stage: The control system (not shown in the figure) issues a retraction command, the drive assembly of the folding door 2 operates, driving the folding door 2 to unfold, so that the top opening of the box 1 is in the open state; at the same time, the drive motor 24 of the synchronous drive source starts, the output end of the drive motor 24 drives the drive wheel 25 to rotate, the drive wheel 25 drives the two driven wheels 26 to rotate synchronously through the transmission belt 27, and the two driven wheels 26 respectively drive the corresponding threaded rods 22 to rotate synchronously. The lifting platform 21 moves upward along the guide column 23 under the drive of the threaded rods 22, thereby driving the support plate 3 to rise to the top opening of the box 1. After the support plate 3 rises to the designated position, the drive motor 24 stops working.

[0035] The second step is the landing and securing of the drone: The drone flies to the top of the support plate 3 using its own positioning system (or with the help of an external positioning device) and lands precisely at the designated parking position on the support plate 3 (a positioning mark can be set on the support plate 3, not shown in the figure); after the drone lands in place, the control system controls the electromagnet 14 to be energized, and the electromagnet 14 generates magnetic force to attract and secure the drone's legs; at the same time, the servo motor 11 starts, and the servo motor 11 drives the synchronous belt 10 to drive the two sliders 9 to move synchronously relative to each other along the sliding guide rail 13. The sliders 9 drive the corresponding limit rods 8 to move towards the drone's legs until the two limit rods 8 are tightly attached to both sides of the drone's legs, realizing the clamping and limiting of the drone's legs, completing the double fixation of the drone, and the servo motor 11 stops working.

[0036] The third step is automatic rotor retraction: After the drone is fixed, the control system controls the telescopic push rod 19 to extend. The telescopic push rod 19 drives the cross brace 15 to move upward along the lifting guide rod 20, which in turn drives the ejector pin 18 to rise to the height corresponding to the drone rotor. After the ejector pin 18 is aligned with the designated pushing position of the rotor, the telescopic push rod 19 stops extending. Subsequently, the four servo motors 16 start synchronously. The servo motors 16 drive the connecting rod 17 to rotate. The connecting rod 17 drives the ejector pin 18 to slowly push against the drone rotor, so that the rotor slowly retracts to the designated storage posture under the force of the ejector pin 18. After the rotor retracts, the servo motors 16 stop working, the telescopic push rod 19 retracts and resets, and drives the cross brace 15, servo motors 16, connecting rod 17 and ejector pin 18 to descend to the initial position.

[0037] Step 4, drone storage: After the rotors are retracted, the control system controls the drive motor 24 to start in reverse. The drive motor 24 drives the drive wheel 25, the transmission belt 27 and the driven wheel 26 to rotate in reverse, which in turn drives the threaded rod 22 to rotate in reverse. The lifting platform 21 moves downward along the guide column 23 under the drive of the threaded rod 22, which drives the support plate 3 and the fixed drone to slowly descend to the designated storage position inside the box 1. After the support plate 3 descends to the position, the drive motor 24 stops working, the drive component of the folding door 2 works, and drives the folding door 2 to close, completing the entire drone recovery and parking process.

[0038] When the drone needs to be retrieved, the control system issues a retrieval command, the drive assembly of the folding door 2 operates, causing the folding door 2 to unfold and the top opening of the housing 1 to open. Subsequently, the drive motor 24 starts, driving the support plate 3 and the drone to the top opening of the housing 1. After the support plate 3 reaches its position, the drive motor 24 stops operating. The control system then controls the servo motor 11 to start in reverse, driving the synchronous belt 10 to move the two sliders 9 and the limit rod 8 synchronously in opposite directions, releasing the clamping limit on the drone's legs. At the same time, the electromagnet 14 is de-energized, releasing the suction fixation on the drone's legs. After the drone is released, it can start and take off normally, completing the drone retrieval operation. After the drone takes off, the control system controls the drive motor 24 to work in reverse, driving the support plate 3 to descend to its initial position inside the housing 1, the folding door 2 closes, and it awaits the next retrieval operation.
