[0028] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0029] The following describes the drone landing device according to an embodiment of the present application with reference to the accompanying drawings.

[0030] like Figures 1-8 As shown, the drone landing device of the embodiment of the present application includes a mounting seat 4, a lifting plate 8 is arranged in the mounting seat 4, the lifting plate 8 is connected to the main lifting motor 9, and the main lifting motor 9 drives the lifting plate 8 to rise and fall.

[0031] Four groups of auxiliary lifting motors 11 are provided on the bottom surface of the lifting plate 8. The lifting ends of each group of auxiliary lifting motors 11 are provided with triangular blocks 12 and short-range linear motors 13. The surface of the lifting plate 8 is provided with four groups of rising grooves that are adapted to the shapes of the triangular blocks 12 and short-range linear motors 13. Between the triangular blocks 12 and the short-range linear motors 13 is a receiving groove that can accommodate the frame of the drone 15, and the moving end of the short-range linear motor 13 is provided with a fixed block 14. The directions of the four groups of receiving grooves match the directions of the four groups of frames of the drone 15 respectively.

[0032] A slide groove is provided in the lifting plate 8, and a slider 17 is slidably provided on the internal slide groove of the lifting plate 8. An adapter rod 18 is connected to the slider 17. A ball screw 21 is rotatably connected to the internal slide groove of the lifting plate 8. The slider 17 is connected to the moving end of the ball screw 21. A servo motor is provided in the internal slide groove of the lifting plate 8, and the ball screw 21 is connected to the output end of the servo motor.

[0033] An adapter block 16 is provided at the front end of the drone 15 , and an adapter slot 19 is provided in the adapter block 16 . The shape of the adapter rod 18 matches the shape of the adapter slot 19 , and a silicone pad is provided at the end of the adapter rod 18 .

[0034] Specifically, the lifting plate 8 within the mounting base 4 is driven up and down by the main lifting motor 9. Four sets of auxiliary lifting motors 11 on its bottom surface are connected to triangular blocks 12 and short-range linear motors 13, respectively. These blocks extend through rising grooves on the surface of the lifting plate 8 to form a receiving groove that matches the frame of the drone 15. The fixing block 14 of the short-range linear motor 13 is used to clamp the frame. The slider 17 within the lifting plate 8 is driven by a servo motor to rotate the ball screw 21, which drives the adapter rod 18 along the slide groove. The silicone pad at the end of the adapter rod 18 inserts into the adapter groove 19 of the adapter block 16 at the front end of the drone 15, achieving mechanical fixation.

[0035] During takeoff and landing, the main lift motor 9 drives the lift plate 8 upward, while the auxiliary lift motor 11 extends the triangular block 12 and the short-range linear motor 13 from the ascending slot, forming a frame receiving slot. After landing, the drone 15 falls into the receiving slot. The short-range linear motor 13 pushes the fixing block 14 to clamp the frame, while the servo motor drives the adapter rod 18 into the adapter slot 19. The silicone pad cushions and strengthens the fixation, ensuring frame stability.

[0036] During the storage process: the adapter rod 18 exits the adapter slot 19, the short-range linear motor 13 releases the frame, the auxiliary lifting motor 11 drives the triangular block 12 and the short-range linear motor 13 to descend back to the ascending slot, and the main lifting motor 9 drives the lifting plate 8 to descend into the mounting seat 4 to complete the storage.

[0037] The device achieves precise fixation and storage of the drone frame through multi-stage lifting, mechanical adaptation and silicone pad cushioning, improves the stability and reliability of the take-off and landing process, and meets the automation requirements of the drone's take-off and landing.

[0038] In one embodiment of the present application, a conductive male contact piece is provided inside the adapter block 16, the connector is connected to the power supply of the drone 15, and a conductive female contact piece is provided on the surface of the adapter rod 18.

[0039] Specifically, the conductive male contact piece on the inside of adapter block 16 is made of copper and connects to the power circuit of drone 15. The conductive female contact piece on the surface of adapter rod 18 is a silver-plated copper piece. The two pieces are well-matched in shape and have low contact resistance. When drone 15 lands, a servo motor drives ball screw 21 to insert adapter rod 18 into adapter slot 19, mechanically securing the frame while the conductive male and female contact pieces fit tightly together, forming an electrical connection loop. This allows for automatic charging of drone 15 or real-time power supply, such as temporary power replenishment during takeoff and landing.

[0040] When the two come into contact, the silicone pad of the adapter rod 18 first cushions the insertion impact, and then the conductive contact piece is turned on, using the low resistance characteristics of the copper-silver material to ensure power transmission efficiency. The silver plating layer can prevent oxidation and improve long-term contact stability, so that the device has both mechanical fixation and electrical connection functions, expanding the energy interaction capabilities of the drone during takeoff and landing.

[0041] In one embodiment of the present application, side panels 1 are provided on both sides of the mounting seat 4, the side panels 1 are streamlined in shape, an electric track 6 is provided on the side panel 1, and the track of the electric track 6 is slidably connected to the horizontal opening plate 2, and a dustproof sealing strip is provided on the inner side of the horizontal opening plate 2, and the dustproof sealing strip is fitted with the edge of the top opening of the mounting seat 4.

[0042] Specifically, the side panels 1 on either side of the mounting base 4 are constructed of aluminum alloy and feature streamlined curved surfaces to reduce wind resistance and enhance aesthetics. A linear ball guide motorized track 6 is longitudinally mounted on the inner side of the side panels 1. The bottom of the horizontal opening panel 2 is connected to the motorized track 6 via a pulley system, driven by a concealed servo motor. A ring-shaped dustproof sealing strip, made of highly elastic silicone rubber, is affixed to the inner edge of the horizontal opening panel 2. Its cross-sectional shape matches the grooved structure of the top opening edge of the mounting base 4, ensuring a tight fit when closed.

[0043] When the drone 15 needs to land, the control system triggers the servo motor of the electric track 6, driving the horizontal opening plate 2 to slide to both sides along the track of the side panel 1, and fully opening the top opening of the mounting seat 4 so that the lifting plate 8 can rise to the receiving position. After the drone lands and is fixed, the servo motor runs in reverse, and the horizontal opening plate 2 closes to the top of the mounting seat 4. At this time, the dustproof sealing strip is squeezed and deformed, filling the gap between the horizontal opening plate 2 and the mounting seat 4, forming a dustproof and waterproof sealing structure, which effectively blocks external dust, rain or debris from entering the interior of the device. The streamlined side panel 1 reduces the resistance of wind to the horizontal opening plate 2 in the outdoor environment, improves the smoothness of the opening and closing action, and the elastic fitting design of the sealing strip ensures the protective performance of the device when it is not working.

[0044] In one embodiment of the present application, a front baffle 3 is provided at the front end of the mounting seat 4, a camera 7 is provided on the front baffle 3, both side edges of the front baffle 3 are streamlined, an image recognition module is provided inside the front baffle 3, and the image recognition module is electrically connected to the camera 7 for identifying the take-off and landing posture of the drone 15.

[0045] Specifically, the front baffle 3 at the front of the mounting base 4 is made of lightweight aluminum alloy, with smooth, streamlined curved edges to reduce air resistance and prevent rain and snow accumulation. A high-definition wide-angle camera 7 is embedded in the center of the front baffle 3. The lens is protected by a scratch-resistant, wear-resistant tempered glass shield. An image recognition module, such as an embedded AI chip, is integrated within the module and electrically connected to the camera 7 via a circuit board. The module contains a built-in gesture recognition algorithm.

[0046] When drone 15 approaches the landing gear, camera 7 captures real-time flight footage of the drone. The image recognition module analyzes the drone's outline, frame position, and tilt angle in real time. Using edge detection and feature point matching algorithms, it identifies its takeoff and landing posture, including horizontal deviation, height difference, and fuselage tilt angle. This recognition data is synchronously transmitted to the device's main control system, which adjusts the movements of the main lift motor 9 and auxiliary lift motor 11 based on these posture parameters to ensure the relative positioning of the lift plate 8 and drone 15. The streamlined side design reduces interference from external airflow on the camera's field of view, improving image acquisition stability. The image recognition module's real-time processing capabilities accurately capture the drone's dynamic posture, providing data support for the takeoff and landing process and ensuring the drone lands safely and accurately within the fixed area of the lift plate 8.

[0047] In one embodiment of the present application, four groups of lifting rods 10 are provided inside the mounting base 4 , the movable ends of the lifting rods 10 are connected to the bottom surface of the lifting plate 8 , and the main lifting motor 9 is connected to the lifting rods 10 .

[0048] A pressure sensor is provided on the surface of the lifting plate 8 , and the pressure sensor is electrically connected to the main lifting motor 9 and the auxiliary lifting motor 11 , and is used to detect the weight of the drone 15 and provide feedback to control the lifting action.

[0049] Specifically, four sets of electric lift rods 10 are symmetrically arranged inside the mounting base 4. These rods are made of high-strength aluminum alloy. Their movable ends are fixedly connected to the four corners of the bottom surface of the lifting plate 8 via bolts, and their fixed ends are connected to the motor bracket at the bottom of the mounting base 4. The main lifting motor 9 drives the four sets of lift rods 10 to rise and fall synchronously via a timing belt or gear set. Four thin-film pressure sensors are embedded in the surface of the lifting plate 8, evenly distributed around the triangular patches 12 and the short-stroke linear motor 13. The sensors are covered with a non-slip and wear-resistant coating and are flush with the surface of the lifting plate 8. They are electrically connected to the control circuits of the main lifting motor 9 and the auxiliary lifting motor 11 via wires.

[0050] When the drone 15 lands on the lifting plate 8, the pressure sensor detects its weight in real time and converts it into an electrical signal, which is then transmitted to the main control system of the device. The main control system first fine-tunes the height of the lifting plate 8 through the main lifting motor 9 according to a preset weight threshold, such as the drone's empty / loaded state, to ensure that the drone frame is aligned with the receiving slots of the triangular block 12 and the short-range linear motor 13. Subsequently, the required fixing force is calculated based on the weight data, and the auxiliary lifting motor 11 is controlled to drive the lifting height of the triangular block 12 and the short-range linear motor 13 so that the receiving slot fits tightly against the drone frame. If the pressure sensor detects an abnormal weight, such as one that exceeds the rated load value of the device, the system will trigger an alarm and prohibit the lifting action to ensure the safety of the equipment. The synchronous drive of the four sets of lifting rods 10 combined with the real-time feedback of the pressure sensor achieves smooth movement and adaptive adjustment of the lifting plate 8, ensuring that drones of different weights can be accurately positioned and fixed.

[0051] In one embodiment of the present application, the short-range linear motor 13 is connected to the fixed block 14 , and a non-slip rubber pad is provided on the surface of the fixed block 14 , and the non-slip rubber pad is provided with a non-slip texture adapted to the frame of the drone 15 .

[0052] Specifically, the moving end of the short-range linear motor 13 is connected to the fixed block 14 through a bolt. The surface of the fixed block 14 facing the drone 15 frame is pasted with a non-slip rubber pad with a high friction coefficient. The surface of the rubber pad is provided with a V-shaped or grid-shaped non-slip texture that matches the shape of the drone frame to enhance the friction during contact.

[0053] In one embodiment of the present application, an arc-shaped opening plate 5 is provided on the inner side of the front baffle 3 through a rotating mounting frame, an arc-shaped motor is provided on the inner side of the front baffle 3, the output end of the arc-shaped motor is connected to one end of the arc-shaped opening plate 5, a solar panel is provided on the outer side of the arc-shaped opening plate 5, and the solar panel is electrically connected to the energy storage battery in the mounting base 4.

[0054] Specifically, the arc motor drives the arc opening plate 5 to rotate around the inside of the front baffle 3, opening and closing it without affecting the drone's takeoff and landing. When the device is in standby mode, the arc opening plate 5 remains extended, and the outer solar panel absorbs light energy and converts it into electricity, which is stored in the energy storage battery to power the device's motor, sensors, and other components, achieving energy self-sufficiency.

[0055] In one embodiment of the present application, mounting brackets 23 are provided on both sides of the mounting seat 4, a luggage rack slot is provided on the bottom surface of the mounting bracket, and an adjustable foot pad is provided at the bottom of the mounting bracket 23, which is connected to the mounting bracket 23 by threads.

[0056] Specifically, the mounting brackets 23 on either side of the mounting base 4 are constructed from a steel frame with rectangular luggage rack slots on their undersides for mounting removable luggage racks. The bottoms of the mounting brackets 23 are threadedly connected to adjustable foot pads. These are cylindrical metal pieces with non-slip rubber pads at the bottom, which can be adjusted in height by rotating them.

[0057] In one embodiment of the present application, a wireless communication module is provided in the mounting seat 4 , and the wireless communication module is connected to an external control terminal to realize remote control of the lifting, opening and closing of the landing gear and the fixing action of the drone 15 .

[0058] Specifically, the user sends operational commands—such as raising and lowering the lift plate, opening and closing the horizontal panel, and clamping the fixed block—through the control terminal. The wireless communication module receives these commands and transmits them to the main controller, triggering the corresponding motors. Simultaneously, real-time data from the device's pressure sensors, cameras, and other sensors is transmitted back to the control terminal via the module, enabling remote monitoring and closed-loop control, further enhancing the drone's automation level in takeoff and landing.

[0059] Specifically, during takeoff and landing, the main lift motor 9 drives the lift plate 8 upward, while the auxiliary lift motor 11 extends the triangular block 12 and the short-range linear motor 13 from the ascending slot to form a frame receiving slot. After landing, the drone 15 falls into the receiving slot. The short-range linear motor 13 pushes the fixing block 14 to clamp the frame, while the servo motor drives the adapter rod 18 into the adapter slot 19. The silicone pad cushions and strengthens the fixation, ensuring frame stability.

[0060] During the storage process: the adapter rod 18 exits the adapter slot 19, the short-range linear motor 13 releases the frame, the auxiliary lifting motor 11 drives the triangular block 12 and the short-range linear motor 13 to descend back to the ascending slot, and the main lifting motor 9 drives the lifting plate 8 to descend into the mounting seat 4 to complete the storage.

[0061] In summary, the drone landing gear of this embodiment, featuring four sets of matching receiving slots and fixing blocks, provides multi-directional stable support, ensuring reliable fixation of the drone in complex environments. The modular design of the overall structure facilitates installation and maintenance, while automated control of the lifting and storage processes reduces manual intervention and improves operational efficiency. It is suitable for rapid deployment and safe operation of drones in fields such as logistics and inspection.
