Description

Technical Field

[0001] This invention relates to the field of ground support equipment technology for unmanned aerial vehicles (UAVs), specifically to a dual-lift UAV intelligent automatic airport. Background Technology

[0002] With the increasing application of drone technology in logistics, inspection, surveying and mapping, the demand for large-scale, routine, and unmanned drone operations is growing. As ground support bases for drones, the performance of intelligent automated airports directly determines the operational efficiency and reliability of drones.

[0003] Currently available automated airports generally suffer from structural design flaws: on the one hand, the lifting mechanisms are mostly single, fixed structures, making it difficult to adapt to the takeoff, landing, and charging altitude requirements of different drone models. Furthermore, the separation of lifting and charging functions leads to cumbersome operational processes. On the other hand, the positioning and clamping accuracy of drones is insufficient, making them prone to displacement during robotic arm operation or charging, affecting docking accuracy and operational safety. In addition, existing airports suffer from poor automation process coordination and weak protection capabilities, making it difficult to achieve fully unattended operation in complex outdoor environments. Summary of the Invention

[0004] Therefore, the present invention provides a dual-lift unmanned aerial vehicle (UAV) intelligent automatic airport to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] According to a first aspect of the present invention, a dual-lift unmanned aerial vehicle (UAV) intelligent automated airport includes:

[0007] The terminal frame assembly serves as the rigid support and installation carrier for the entire airport.

[0008] The three-axis robotic arm is installed inside the terminal frame assembly and is used to precisely grasp and transport the UAV in three-dimensional space.

[0009] The clamping mechanism is installed inside the terminal frame assembly and is used for multi-dimensional positioning and fixation of the UAV after it docks.

[0010] The dual lifting platform, located within the terminal frame assembly, is used to carry the UAV and precisely adjust its operating altitude;

[0011] A sliding cover, which can be opened and closed, is installed on the top of the terminal frame assembly to protect the internal equipment;

[0012] The dual-lift platform includes:

[0013] The main column integrates a lifting drive mechanism, such as a lead screw and nut or a gear and rack mechanism.

[0014] The lifting platform is connected to the output end of the lifting drive mechanism of the main column and is used to directly support the drone;

[0015] The charging compartment is fixedly installed on the lifting platform, and its position and interface are precisely matched with the charging interface of the drone to be operated, so as to realize automatic charging after being lifted into place.

[0016] Furthermore, the dual lifting platform also includes a charging box, which is electrically connected to the charging compartment and is used to intelligently adjust charging parameters according to the battery status.

[0017] Furthermore, the three-axis manipulator includes: a horizontally arranged X-axis module, a vertically arranged Z-axis module, a Y-axis module perpendicular to the X-axis, and a Y-axis actuator installed at the end of the Y-axis module, which realizes omnidirectional grasping operation of the UAV through multi-axis linkage.

[0018] Furthermore, the clamping mechanism includes a lateral aircraft push rod motor group driven by a lateral motor group and a longitudinal aircraft push rod driven by a longitudinal motor group, which together constrain the UAV from both lateral and longitudinal dimensions.

[0019] Furthermore, the sliding cover includes an upper cover, a power-providing opening and closing motor assembly, a drive shaft, and a synchronous belt system, which drives the upper cover to open and close smoothly via a synchronous belt connecting plate.

[0020] In addition, the terminal frame assembly also integrates an electrical control cabinet for centralized control, a hard drive for data storage, an air conditioner for maintaining a constant temperature environment, batteries and inverters for emergency power supply, and fire extinguishers for safety.

[0021] This invention offers the following advantages: It provides a dual-lift intelligent automated airport for unmanned aerial vehicles (UAVs). By directly integrating the charging compartment into the lifting platform, the UAV can begin charging immediately during or after lift-off without additional transfer or secondary positioning, greatly simplifying the workflow and improving resupply efficiency. The combination of a three-axis robotic arm and a bidirectional clamping mechanism achieves millimeter-level precision control throughout the entire process from UAV grasping, handling, to fixing, effectively preventing displacement and swaying during operation and ensuring the stability and reliability of charging docking. The centralized coordination of the sliding cover, robotic arm, clamping mechanism, and lifting platform via the electrical control cabinet enables fully automated take-off, landing, and resupply of the UAV. Simultaneously, the integrated protective sliding cover and internal environmental control system (air conditioning, fire extinguishers, etc.) allow the automated airport to adapt to complex outdoor climates, achieving true unmanned operation. The rational layout of each functional module within the airport frame assembly ensures smooth operation of the robotic arm between the clamping station and the lifting platform, making it suitable for various UAV models and sizes.

[0037] Example 1

[0038] like Figures 1 to 6 As shown in the first aspect embodiment of the present invention, a dual-lift unmanned aerial vehicle (UAV) intelligent automatic airport is provided. The main body of the automatic airport is the terminal frame assembly 1, which is a metal frame structure that provides a mounting base for all other components. Inside the terminal frame assembly 1, an electrical control cabinet 12 is arranged as the control center, which integrates a PLC controller or industrial computer for processing signals and controlling the timing of the actions of each actuator. A hard disk 13 is used to store flight logs, system data, etc. An air conditioner 14 is used to regulate the internal temperature to ensure that the electronic components and UAV batteries are in the optimal working environment. A battery 15 and an inverter 16 constitute an uninterruptible power supply system to provide emergency power when the main power supply is interrupted. A fire extinguisher 17 serves as a fire protection unit and can be automatically or manually triggered.

[0039] In the central area inside the terminal frame assembly 1, there is a dual lifting platform 4; its core component is a vertically fixed main column 41, and a servo motor driven screw and nut mechanism is installed inside the main column 41; the lifting platform 42 is fixedly connected to the nut seat of the screw, and can be precisely raised and lowered along the main column 41 under the drive of the servo motor; a charging compartment 43 is fixedly installed on the upper surface of the lifting platform 42, and a pin-type or contact-type charging interface corresponding to the charging contacts on the bottom of the UAV is provided inside the charging compartment 43; the charging box 44 is installed on the side wall of the terminal frame assembly 1, and its output end is electrically connected to the charging compartment 43, and its input end is connected to an external power source or battery 15, which is used to convert AC power into DC power suitable for UAV batteries, and has overcurrent and overvoltage protection functions;

[0040] Above the dual lifting platform 4, directly above the lifting platform 42, there is a clamping mechanism 3. This mechanism includes lateral motor groups 32 symmetrically arranged on both sides and lateral aircraft push rod motor groups 31 driven by them, as well as longitudinal motor groups 34 arranged at the front and rear ends and longitudinal aircraft push rods 33 driven by them. When the UAV lands on the lifting platform 42, the lateral and longitudinal motor groups drive the corresponding push rods to extend, firmly fixing the UAV's landing gear or fuselage from all sides to ensure its position is absolutely accurate.

[0041] Inside one side of the terminal frame assembly 1, a three-axis manipulator 2 is installed. This manipulator consists of an X-axis module 21 that provides a long horizontal stroke, a Z-axis module 22 that provides vertical lifting, and a Y-axis module 23 that provides a short horizontal stroke. The end of the Y-axis module 23 is equipped with a Y-axis actuator 24. In this embodiment, the Y-axis actuator 24 is a pneumatic gripper used to grab and replace the battery on the UAV. The movement space of the X, Y, and Z axes covers the fixed position of the clamping mechanism 3 and the lifting path of the dual lifting platform 4.

[0042] A sliding cover 5 is installed on the top of the terminal frame assembly 1; the opening and closing motor unit 52 drives the transmission shaft 53 to rotate, and the transmission shaft 53 drives the synchronous belts 55 on both sides to move. Through the fixed connection of the synchronous belt connecting plate 54, the power is transmitted to the upper cover 51, thereby realizing the automatic opening and closing of the upper cover 51 along the guide rail.

[0043] Detailed Work Process:

[0044] 1. Opening and Landing: After receiving the command, the sliding cover 5 opens automatically; the drone lands and hovers, then slowly lands on the lifting platform 42;

[0045] 2. Positioning and clamping: After the drone comes to a stop, the horizontal and vertical push rods of the clamping mechanism 3 move simultaneously to precisely fix the drone in the predetermined position of the lifting platform 42;

[0046] 3. Lifting and charging: After the device is fixed in place, the main column 41 of the dual lifting platform 4 drives the lifting platform 42 to descend to the set charging height. At this time, the interface of the charging compartment 43 is tightly connected with the interface of the drone, and the charging box 44 is activated to start charging the drone.

[0047] 4. Battery replacement if needed: If the system determines that the battery needs to be replaced, the three-axis robot 2 is activated. Through the linkage of the X, Y and Z axes, the Y-axis actuator 24 is moved above the drone to accurately grab the depleted battery and transport it to the battery storage position. Then, a fully charged battery is grabbed and installed back into the drone.

[0048] 5. Reset and takeoff: After the operation is completed, the robotic arm 2 returns to its original position, the dual lifting platform 4 lifts the drone to the initial takeoff and landing height, the clamping mechanism 3 releases, and the drone takes off to perform the mission;

[0049] 6. Close protection: After the drone leaves the field, the sliding cover 5 will automatically close, waiting for the next mission.

[0050] Second Embodiment

[0051] Based on Embodiment 1, this embodiment improves the Y-axis actuator 24 of the three-axis manipulator 2 to enhance its adaptability to different models of drones and their battery modules; the technical solution of this embodiment is described in detail below.

[0052] See Figures 1 to 6 This embodiment provides a dual-lift unmanned aerial vehicle (UAV) intelligent automated airport, including:

[0053] The terminal frame assembly 1 serves as the rigid support and installation carrier for the entire airport. Inside the terminal frame assembly 1, an electrical control cabinet 12 is integrated, acting as the control center. This cabinet houses a PLC controller or industrial computer, used to receive instructions, process signals, and coordinate the timing and logic of the actions of various actuators, including the three-axis robotic arm 2, clamping mechanism 3, dual lifting platform 4, and sliding cover 5, achieving fully automated control. A hard disk 13, installed within the terminal frame assembly 1 and electrically connected to the electrical control cabinet 12, stores UAV operational data such as takeoff and landing times, charging records, fault information, system operation logs, and control programs, providing data support for subsequent data analysis and system optimization. An air conditioner 14, installed within the terminal frame assembly 1, maintains... The automated airport maintains a constant temperature environment to prevent excessively high or low temperatures from affecting the performance and lifespan of electronic control components, batteries, and other parts, ensuring stable system operation. Battery 15, installed within the terminal frame assembly 1, provides backup power for the automated airport. In the event of an external power outage, it can temporarily maintain critical system functions such as data storage and emergency shutdown, improving system reliability. Inverter 16 is electrically connected to battery 15 to convert DC power to AC power, providing power support for equipment requiring AC power and ensuring power supply compatibility. Fire extinguisher 17, installed within the terminal frame assembly 1, serves as a safety device. In the event of an electrical fire or other emergency, it can be automatically or manually activated to quickly extinguish the fire and protect the automated airport and drones.

[0054] In the central area inside the terminal frame assembly 1, a dual lifting platform 4 is installed. The dual lifting platform 4 includes a main column 41, a lifting platform 42, a charging compartment 43, and a charging box 44. The main column 41 is vertically fixed and serves as the support and transmission component for lifting. It integrates a lifting drive mechanism, which can be a screw and nut mechanism, a gear and rack mechanism, or a linear motor. The lifting platform 42 is fixedly connected to the output end of the lifting drive mechanism of the main column 41. It can be vertically and smoothly lifted and lowered along the main column 41 under the drive of the drive mechanism, providing different working positions for UAVs, such as adapting to the take-off and landing heights of different models, or enabling UAVs to accurately dock with the charging compartment. The surface of the lifting platform 42 can be designed with positioning grooves, anti-slip structures, etc., and in conjunction with the clamping mechanism 3, further ensures... To ensure the stability of the drone during the lifting process, the charging compartment 43 is fixedly installed on the lifting platform 42, and its position is precisely matched with the charging interface of the drone to be operated. The charging compartment 43 is equipped with a pin-type or contact-type charging interface corresponding to the charging contacts on the bottom of the drone. When the lifting platform 42 lifts the drone to the designated height, the charging compartment 43 can precisely connect with the drone's charging interface to realize power transmission. The charging box 44 is installed on the side wall of the terminal frame assembly 1. Its output end is electrically connected to the charging compartment 43, and its input end is connected to an external power source or battery 15. It is used to provide power supply and charging management for the charging compartment 43. It can intelligently adjust the charging voltage and current according to the drone's battery parameters to achieve fast and safe charging. It also has overcharge protection, short circuit protection and other functions.

[0055] Above the dual lifting platform 4, directly above the lifting platform 42, is a clamping mechanism 3. The clamping mechanism 3 is used for precise positioning and stable fixation of the UAV within the automated airport. It consists of a lateral aircraft push rod motor assembly 31, a lateral motor assembly 32, a longitudinal aircraft push rod 33, and a longitudinal motor assembly 34, constraining the UAV in both lateral and longitudinal dimensions. The lateral clamping assembly includes lateral motor assemblies 32 symmetrically arranged on both sides and a lateral aircraft push rod motor assembly 31 driven and connected to the lateral motor assembly 32. The lateral motor assembly 32 drives the lateral aircraft push rod motor assembly 31 to extend or retract laterally, clamping the UAV from both lateral sides and restricting its movement. The longitudinal clamping assembly includes a longitudinal motor group 34 arranged at the front and rear ends and a longitudinal aircraft push rod 33 driven by the longitudinal motor group 34. The longitudinal motor group 34 drives the longitudinal aircraft push rod 33 to move longitudinally and clamp the UAV from the longitudinal front-rear direction. The lateral clamping and longitudinal clamping work together to firmly fix the UAV's landing gear or body in the designated position, ensuring that its position is absolutely accurate during subsequent lifting, charging and robotic arm operation, and avoiding displacement or shaking. The clamping station of the clamping mechanism 3 is located directly above the lifting platform 42 of the dual lifting platform 4. When the UAV is fixed by the clamping mechanism 3, its bottom is supported on the lifting platform 42.

[0056] Inside the terminal frame assembly 1, a three-axis robotic arm 2 is installed on one side. The three-axis robotic arm 2 is the core actuator for precise grasping and handling of the UAV, consisting of an X-axis module 21, a Z-axis module 22, a Y-axis module 23, and a Y-axis actuator 24. The X-axis module 21 is horizontally positioned to provide linear motion along the X-axis, providing the basis for the robotic arm's wide-range horizontal movement. It can adjust the robotic arm's position on the X-axis according to the UAV's docking location, ensuring the accuracy of the grasping starting point. The Z-axis module 22 is vertically positioned to achieve vertical movement along the Z-axis. The height of the robotic arm is adjusted to adapt to the drone grasping needs at different lifting heights. The Y-axis module 23 is horizontally set and perpendicular to the X-axis module 21, and is responsible for linear movement along the Y-axis direction, further refining the position adjustment of the robotic arm on the horizontal plane. In conjunction with the X-axis module 21, it achieves precise positioning of the robotic arm in the plane. The movement space of the X-axis module 21, Y-axis module 23, and Z-axis module 22 covers the fixed position of the clamping mechanism 3 and the lifting path area of ​​the dual lifting platform 4, ensuring that the robotic arm can operate smoothly between the clamping position and the lifting platform.

[0057] The improvement of this embodiment is that a Y-axis actuator 24 is installed at the end of the Y-axis module 23. This actuator is a vacuum suction cup array. The vacuum suction cup array consists of multiple independent or linked vacuum suction cups, and each vacuum suction cup is connected to a vacuum generator through a pipeline. The vacuum suction cup array can adaptively adsorb according to the surface shape of the object being operated, such as the surface of the drone body with different curvatures, the smooth battery cover, or the surface of the battery module. The negative pressure generated by the vacuum generator enables the drone to be grasped, transported, and released without damage. Compared with the pneumatic gripper in the first embodiment, the vacuum suction cup array does not require the design of special clamps for specific battery shapes. It can be compatible with more models of drones and their battery modules. Moreover, the adsorption force is evenly distributed, avoiding local stress concentration that may be caused by the gripper, effectively protecting the drone body and battery shell, reducing the risk of damage, and further enhancing the versatility and adaptability of the present invention.

[0058] A sliding cover 5 is installed on the top of the terminal frame assembly 1. The sliding cover 5 is used to protect the internal equipment of the automated airport without affecting the normal operation of the UAV. It consists of an upper cover 51, an opening and closing motor assembly 52, a drive shaft 53, a synchronous belt connecting plate 54, and a synchronous belt 55. The opening and closing motor assembly 52 provides power for the opening and closing of the sliding cover 5, which drives the drive shaft 53 to rotate and drives the synchronous belt 55 to move. The drive shaft 53 and the synchronous belt 55 serve as transmission components, transmitting the power of the opening and closing motor assembly 52 to the upper cover 51. The synchronous belt connecting plate 54 connects the synchronous belt 55 to the upper cover 51, so that the upper cover 51 opens or closes along a preset track under the drive of the synchronous belt 55. When the UAV needs to take off, land, or operate, the sliding cover 5 opens automatically. After the operation is completed, the sliding cover 5 closes automatically to prevent dust, rainwater, etc. from entering the interior of the automated airport and protect the equipment.

[0059] Detailed Work Process:

[0060] 1. Opening and Landing: After receiving the command, the electrical control cabinet 12 controls the opening and closing motor group 52 to start, which drives the upper cover 51 to open automatically along the track through the transmission shaft 53 and the synchronous belt 55; the UAV flies over the automatic airport, lands and hovers, and then slowly lands on the lifting platform 42.

[0061] 2. Positioning and clamping: After the UAV comes to a stop, the electrical control cabinet 12 controls the clamping mechanism 3 to start working: the horizontal motor group 32 drives the horizontal aircraft push rod motor group 31 to clamp the UAV from both sides in the horizontal direction, while the vertical motor group 34 drives the vertical aircraft push rod 33 to clamp the UAV from the longitudinal front and rear direction. The two work together to fix the UAV precisely in the predetermined position of the lifting platform 42.

[0062] 3. Lifting and charging: After the device is fixed, the electrical control cabinet 12 controls the lifting drive mechanism inside the main column 41 of the dual lifting platform 4 to start, driving the lifting platform 42 to descend to the set charging height; at this time, the interface of the charging compartment 43 fixed on the lifting platform 42 is tightly connected with the charging interface at the bottom of the drone, the charging box 44 starts, and intelligently adjusts the charging voltage and current according to the drone battery parameters to start charging the drone.

[0063] 4. Battery Replacement If Required: If the system determines that the battery needs to be replaced based on the preset program or real-time monitoring data, the control cabinet 12 will control the three-axis robot arm 2 to start; the X-axis module 21 and Y-axis module 23 will work together to adjust the horizontal position, and the Z-axis module 22 will adjust the vertical height, so that the Y-axis actuator 24, i.e., the vacuum suction cup array, moves to above the drone battery; the vacuum suction cup array generates negative pressure through the vacuum generator to accurately adsorb and grab the depleted battery and move it to the battery storage position, and then adsorb and grab the fully charged battery, move it to above the drone, and install the fully charged battery back into the drone; the non-destructive adsorption characteristics of the vacuum suction cup array ensure that no scratches or damage are caused to the battery or the surface of the drone during the gripping process;

[0064] 5. Reset and takeoff: After the battery is replaced or charged, the three-axis robot 2 returns to its initial position; the electrical control cabinet 12 controls the main column 41 of the dual lifting platform 4 to drive the lifting platform 42 to rise to the initial takeoff and landing height; the electrical control cabinet 12 controls the horizontal aircraft push rod motor group 31 and the vertical aircraft push rod 33 of the clamping mechanism 3 to retract, releasing the drone; the drone takes off and performs subsequent tasks.

[0065] 6. Closing the protection: After the drone leaves the field, the electrical control cabinet 12 controls the opening and closing motor group 52 to start in reverse, which drives the upper cover 51 to automatically close along the track through the transmission shaft 53 and the synchronous belt 55, waiting for the next mission.

[0066] Through the above-described structural setup and process control, this embodiment achieves fully automated and intelligent operation of the UAV from landing, positioning, clamping, lifting, charging, battery replacement to takeoff. By directly integrating the charging compartment 43 onto the lifting platform 42, the lifting and charging functions are integrated, allowing charging to begin immediately without additional transportation or secondary positioning, greatly simplifying the operation process and improving resupply efficiency. Through the coordinated operation of the three-axis manipulator 2 and the clamping mechanism 3, millimeter-level precision control is achieved throughout the entire process from UAV grabbing, handling to fixing, effectively preventing displacement and shaking during operation and ensuring the stability and reliability of charging docking. By setting the Y-axis actuator 24 as a vacuum suction cup array, non-destructive and universal grabbing of different UAV models and their battery modules is achieved, further enhancing the intelligence level and compatibility of the automated airport. Through the automatic opening and closing of the sliding cover 5 and the integration of the internal environmental control system, air conditioning, fire extinguishers, etc., the automated airport can adapt to complex outdoor climate environments and achieve true unmanned operation.

[0067] The beneficial effects of this embodiment are explained as follows:

[0068] This embodiment uses a vacuum suction cup array as the Y-axis actuator 24, which has the following additional advantages compared to traditional pneumatic grippers:

[0069] 1. Enhanced compatibility: No need to design special clamps for different battery or airframe models; it can adaptively adsorb objects of various surface shapes and materials, making it suitable for more types and models of drones.

[0070] 2. Non-destructive gripping: The evenly distributed adsorption force avoids local stress concentration that may be caused by the gripper, effectively protecting the drone body and battery casing, and reducing the risk of damage caused by excessive gripping force;

[0071] 3. More flexible positioning: The suction cup array can adjust the adsorption point according to the contour of the object being grasped. Even if there is a slight deviation in the landing position of the drone, it can achieve precise grasping through fine-tuning during the adsorption process, which improves the fault tolerance of the system.

[0072] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
