Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) take-off and landing technology, specifically to a UAV take-off and landing platform. Background Technology

[0002] Unmanned aerial vehicles (UAVs) have advantages such as small size, low cost, and ease of use. UAVs can typically fly autonomously beyond visual range, carry a certain payload, and perform tasks such as reconnaissance, aerial photography, and surveillance. They can calculate the probability of mission success based on various complex conditions, including weather, changes in the ground environment, and even the position of aerial obstacles, and automatically execute or abandon the mission.

[0003] In both civilian and scientific research fields, drones have numerous applications, such as near-shore exploration, highway and railway maintenance, and power line inspection. To achieve these applications, various devices need to be mounted on the drones to control them and execute patrol missions. After completing their missions, the drones land on landing platforms for charging, battery swapping, or the next patrol mission. Currently, drones are typically secured to landing platforms manually or magnetically. However, these methods are complex and prone to instability in strong winds, making them unsuitable for unattended and highly reliable operations. Utility Model Content

[0053] This application discloses a landing platform for unmanned aerial vehicles (UAVs) used to receive and secure the UAV 8.

[0054] In this embodiment, please refer to Figure 1 As shown, the UAV 8 includes a fuselage 82 and landing gear 81. The landing gear 81 is located at the bottom of the fuselage 82. The landing gear 81 includes support arms 811 and support rods 812. There are two support arms 811, symmetrically arranged on the left and right sides of the belly of the fuselage 82. There are two support rods 812, extending in the front-rear direction, respectively located at the bottom of the corresponding support arms 811.

[0055] Please see Figures 2-4 As shown, the UAV's landing platform includes a frame 1, a support platform 2, a fixing block 3, a cover plate 4, and a first drive mechanism 5. The frame 1 has a base plate 11 at its bottom. The base plate 11 includes a main body and a frame edge. The support platform 2 is horizontally and vertically mounted within the frame 1 via the first drive mechanism 5, and is positioned above the base plate 11. A through hole 21 is formed in the center of the support platform 2. The cover plate 4 is hinged to the edge of the through hole 21. A torsion spring 6 is provided at the connection between the cover plate 4 and the support platform 2. In this embodiment, the through hole 21 is rectangular. The front end of the cover plate 4 is hinged to the support platform 2 via a pivot. The torsion spring 6 is sleeved on the pivot, and its two ends are connected to the cover plate 4 and the support platform 2, respectively.

[0056] The torsion spring 6 is adapted to drive the cover plate 4 to rotate, so that the cover plate 4 seals the through hole 21. In this embodiment, both the top surface of the support platform 2 and the top surface of the cover plate 4 are provided with patterns. When the cover plate 4 seals the through hole 21, the pattern on the top surface of the support platform 2 and the pattern on the top surface of the cover plate 4 constitute a complete QR code or other image recognition mark for the UAV 8 to identify, thereby ensuring that the UAV 8 lands accurately on the landing platform. The accurate landing of the UAV 8 using a QR code or other image recognition mark is existing technology and will not be described in detail.

[0057] For further details, please refer to Figure 4 As shown, a limiting structure 22 is provided on the inner wall surface of the through hole 21, and the limiting structure 22 is located below the cover plate 4. The limiting structure 22 is adapted to limit the cover plate 4 when the cover plate 4 seals the through hole 21, so that the top surface of the cover plate 4 is flush with the top surface of the support platform 2, thereby ensuring the flatness of the QR code or other image recognition mark formed by the pattern on the top surface of the support platform 2 and the pattern on the top surface of the cover plate 4.

[0058] The fixing block 3 is vertically arranged, with its lower end fixed to the base plate 11 and its upper end adapted to have a through hole 21. A slot 31 is formed at the top of the upper end of the fixing block 3. The slot 31 is adapted to engage with the lower part of the fuselage 82. In this embodiment, the slot 31 is adapted to engage with the lower part of the underside of the fuselage 82. Notches 32 are provided on the left and right side walls of the slot 31. The notches 32 are adapted to avoid the support rod 812 of the landing gear 81. A heat dissipation hole 33 is formed at the center of the bottom surface of the slot 31 to allow heat dissipation from the underside of the UAV 8.

[0059] When the support platform 2 supports the landing gear 81 of the drone 8, the cover plate 4 is located inside the landing gear 81 and will not interfere with the landing gear 81. Specifically, when the drone 8 has not landed on the support platform 2 (e.g. Figure 2 As shown), cover plate 4 seals through hole 21, and fixing block 3 is placed below cover plate 4. When drone 8 lands on support platform 2 (as shown) Figure 7As shown), the top surface of the support platform 2 effectively supports the landing gear 81, and the cover plate 4 is located between the two support rods 812. Subsequently, the first drive mechanism 5 drives the support platform 2 to descend, causing the fixing block 3 to pass through the through hole 21 and push open the cover plate 4. During this process, the cover plate 4 will not interfere with the landing gear 81. When the slot 31 engages with the lower part of the fuselage 82, and the top surface of the support platform 2 still effectively supports the landing gear 81 (as shown), the support platform 2 effectively supports the landing gear 81. Figure 8 As shown), the support platform 2 stops descending. At this time, the landing platform can effectively support and fix the drone 8.

[0060] Please see Figure 2 As shown, guide rods 13 are vertically arranged inside the frame 1. In this embodiment, there are four guide rods 13, which are set at the four corners of the base plate 11. The four corners of the support platform 2 are slidably connected to the corresponding guide rods 13 through guide sleeves.

[0061] Please see Figure 2 and Figure 5 As shown, a screw 12 is vertically and rotatably mounted inside the frame 1. In this embodiment, there are two screws 12, distributed on the left and right sides of the support platform 2. The lower end of the screw 12 is rotatably mounted on the base plate 11 via a support frame. The support platform 2 is threadedly connected to the corresponding screw 12 via a sleeve. The first drive mechanism 5 is fixed on the support platform 2 and drives the screw 12 to rotate via the first transmission mechanism 52, thereby raising and lowering the support platform 2.

[0062] The first drive mechanism 5 includes a first motor 51 and a first transmission mechanism 52. Specifically, the fixing block 3 has a hollow structure. The first motor 51 is fixed inside the fixing block 3. The output shaft of the first motor 51 is vertically arranged inside the fixing block 3. The first transmission mechanism 52 is arranged between the support platform 2 and the base plate 11. One end of the first transmission mechanism 52 is connected to the screw 12, and the other end extends into the fixing block 3 and is connected to the output shaft of the first motor 51.

[0063] Specifically, two first driving pulleys are coaxially mounted on the output shaft of the first motor 51. Each screw 12 is coaxially mounted on a first driven pulley. The first transmission mechanism 52 is a transmission belt. The first driving pulleys are connected to the first driven pulleys via corresponding first transmission mechanisms 52. When the output shaft of the first motor 51 drives the first driving pulleys to rotate, the first driving pulleys drive the corresponding first driven pulleys to rotate via the first transmission mechanisms 52, thereby causing the corresponding screw 12 to rotate.

[0064] Please see Figure 3 , Figure 6 and Figure 7 As shown, a positioning mechanism 7 is provided on the top of the support platform 2. The positioning mechanism 7 is distributed around the periphery of the cover plate 4 and is suitable for fixing and positioning the lower end of the landing gear 81.

[0065] In this embodiment, the positioning mechanism 7 includes two first rods 71, two second drive mechanisms 72, two second rods 73, and two third drive mechanisms 74.

[0066] Two first rods 71 ​​are slidably mounted on the top of the support platform 2 and distributed on the left and right sides of the cover plate 4. Each first rod 71 extends in the front-to-back direction, and its front and rear ends are slidably connected to the support platform 2 via sliders. A second drive mechanism 72 is provided between the front ends of the two first rods 71, and another second drive mechanism 72 is provided between the rear ends of the two first rods 71. The second drive mechanisms 72 are adapted to adjust and control the opening and closing distance between the two first rods 71 ​​to fix and position the left and right sides of the landing gear 81.

[0067] In this embodiment, the second drive mechanism 72 includes a second motor 721 and a second transmission mechanism 722. Specifically, the second motor 721 is fixed on the support platform 2. The output shaft of the second motor 721 is vertically arranged, and two second drive wheels are coaxially arranged on the output shaft. Two second driven wheels are arranged on the support platform 2. The two second driven wheels are arranged on the same side of the support platform 2 as the corresponding second motor 721, and the two second driven wheels are symmetrically distributed on the left and right sides of the output shaft of the second motor 721. The second transmission mechanism 722 is a transmission belt. The front and rear ends of the first rod 71 are respectively connected to the corresponding transmission belt through connecting frames. The second drive wheels are respectively connected to the second driven wheels through the corresponding second transmission mechanism 722. When the output shaft of the second motor 721 drives the second drive wheel to rotate, the second drive wheel drives the corresponding second driven wheel to rotate through the second transmission mechanism 722, and the second transmission mechanism 722 drives the two first rods 71 ​​to center and clamp the left and right sides of the landing gear 81. Among the existing technologies, Chinese Patent Publication No. CN216037692U discloses a paper roll centering auxiliary device that uses a transmission belt, driven wheel, driving wheel, and motor to achieve the centering action. Therefore, the use of a second motor 721 and a second transmission mechanism 722 to achieve the centering action is existing technology.

[0068] Two second rods 73 are slidably mounted on the top of the support platform 2 and distributed on the front and rear sides of the cover plate 4. The second rods 73 are located above the first rod 71. The second rods 73 extend in the left-right direction, and their left and right ends are slidably connected to the support platform 2 via sliders. A third drive mechanism 74 is provided between the front ends of the two second rods 73, and another third drive mechanism 74 is provided between the rear ends of the two second rods 73. The third drive mechanisms 74 are adapted to control the opening and closing distance between the two second rods 73 to fix and position the front and rear sides of the landing gear 81.

[0069] In this embodiment, the third drive mechanism 74 includes a third motor 741 and a third transmission mechanism 742. Specifically, the third motor 741 is fixed on the support platform 2. The output shaft of the third motor 741 is vertically arranged, and two third drive wheels are coaxially arranged on the output shaft. Two third driven wheels are arranged on the support platform 2. The two third driven wheels are arranged on the same side of the support platform 2 as the corresponding third motor 741, and the two third driven wheels are symmetrically distributed on the front and rear sides of the output shaft of the third motor 741. The third transmission mechanism 742 is a transmission belt. The left and right ends of the second rod 73 are respectively connected to the corresponding transmission belt through connecting frames. When the output shaft of the third motor 741 drives the third drive wheel to rotate, the third drive wheel drives the corresponding third driven wheel to rotate through the third transmission mechanism 742, and the third transmission mechanism 742 drives the two second rods 73 to center and clamp the front and rear sides of the landing gear 81.

[0070] The working principle of the landing platform of this drone is as follows:

[0071] When drone 8 fails to land on support platform 2, such as Figure 2 As shown, the cover plate 4 seals the through hole 21, and the fixing block 3 is placed below the cover plate 4;

[0072] When drone 8 lands on support platform 2, as Figure 7 As shown, the top surface of the support platform 2 effectively supports the landing gear 81, and the cover plate 4 is located between the two support rods 812;

[0073] Subsequently, the second drive mechanism 72 drives the two first rods 71 ​​to center and clamp the left and right sides of the landing gear 81; the third drive mechanism 74 drives the two second rods 73 to center and clamp the front and rear sides of the landing gear 81.

[0074] Subsequently, the first drive mechanism 5 drives the support platform 2 to descend, so that the fixing block 3 passes through the through hole 21 and pushes open the cover plate 4. During this process, the cover plate 4 will not interfere with the landing gear 81; wait for the slot 31 to engage with the lower part of the fuselage 82, such as Figure 8 As shown, when the top surface of the support platform 2 still effectively supports the landing gear 81, the support platform 2 stops descending.

[0075] When the drone 8 needs to take off, both first rods 71 ​​and both second rods 73 move away from the landing gear 81. Then, the first drive mechanism 5 drives the support platform 2 to descend and rise until the fixed block 3 is placed below the support platform 2, and the cover plate 4 is reset under the action of the torsion spring 6 so that the cover plate 4 seals the through hole 21. After that, the drone 8 takes off.

[0076] In summary, this invention, through the cooperation of a support platform, fixing block, cover plate, and torsion spring, ensures that a drone in flight can effectively recognize the complete QR code or other image recognition mark formed by the top surface of the support platform and the top surface of the cover plate. It also allows for the locking and securing of the drone after it lands on the support platform. The fixing block and positioning mechanism effectively fix and position the lower part of the drone body and landing gear, ensuring the drone remains firmly secured even in strong winds. The landing platform of this invention is simple to operate, requiring no manual binding of the drone for secure fixation.

[0077] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
