Technical Field

[0001] This application relates to the field of unmanned aerial vehicles (UAVs), and in particular to an automated take-off and landing platform for UAVs used for site analysis. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own programmed control devices. The term "UAV" is actually a general term for unmanned aerial vehicles, which, from a technical perspective, can be categorized as: unmanned fixed-wing aircraft, unmanned vertical takeoff and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders, among others. Compared to manned aircraft, they have advantages such as smaller size, lower cost, ease of use, lower requirements for the operational environment, and stronger battlefield survivability.

[0017] The following is in conjunction with the appendix Figure 1 Figure 5 provides a further detailed description of this application.

[0018] This application discloses an automated take-off and landing platform for unmanned aerial vehicles (UAVs) used for site analysis. For example... Figure 1 , 3As shown in Figure 5, an automatic take-off and landing platform for unmanned aerial vehicles (UAVs) used for site analysis includes a cabin 1. A landing platform 2 is located inside the cabin 1, and a UAV body 3 is positioned above the landing platform 2. The landing platform 2 supports the UAV body 3. Two clamping plates 4 are slidably connected to the upper surface of the landing platform 2. Each clamping plate 4 has two limiting grooves 5 on its outer surface. Two clamping rods 10 are located above the landing platform 2, with both ends of each clamping rod 10 located inside the corresponding limiting grooves 5. Each clamping plate 4 is fixedly connected to a clamping block 6. Two clamping strips 7 are slidably connected to the lower surface of the landing platform 2. Each clamping block 6 has a first fixing rod 8 threadedly connected inside it. All are parallel to the clamping rod 10. One end of each first fixing rod 8 is rotatably connected to the landing platform 2. Each clamping bar 7 is threaded with a second fixing rod 9. One end of each second fixing rod 9 is rotatably connected to the landing platform 2. Both ends of each clamping rod 10 are rotatably connected to the corresponding clamping bar 7. The clamping plate 4 and the clamping rod 10 are mutually limited by the limiting groove 5. When the first fixing rod 8 rotates, the first fixing rod 8 drives the clamping block 6 and the clamping plate 4 to slide along the axial direction of the clamping rod 10. When the second fixing rod 9 rotates, the second fixing rod 9 drives the clamping bar 7 and the clamping rod 10 to move along the axial direction of the second fixing rod 9, thereby clamping and fixing the landing gear of the UAV body 3.

[0019] Please see Figure 5 Each first fixed rod 8 has a first gear 12 fixedly connected to its other end, and each second fixed rod 9 has a second gear 13 fixedly connected to its other end.

The other end of each second link 25 is rotatably connected to the landing platform 2. The second drive bar 24 drives the landing platform 2 to move up and down through the second links 25, thereby preventing the rotor blades of the UAV body 3 from colliding with the inner wall of the cabin 1 during takeoff or landing.

[0021] Please see Figure 2A second motor is fixedly installed inside the cabin 1. A second screw 17 is fixedly connected to the output end of the second motor. The outer surface of the second screw 17 is provided with a bidirectional thread. Both ends of the second screw 17 are fixedly connected to the interior of the cabin 1. The outer surface of the second screw 17 is threadedly connected to the interior of two second drive bars 24. Two second limit rods 18 are provided on both sides of the second screw 17. The outer surface of the second limit rod 18 is slidably connected to the interior of the second drive bar 24, thereby supporting the second drive bar 24. Both ends of each second limit rod 18 are fixedly connected to the interior of the cabin 1. The second screw 17 drives the two second drive bars 24 to move towards each other along the second limit rod 18 by rotation.

[0022] Please see Figure 1 , 3 The upper surface of the cabin 1 is provided with two doors 21. Each door 21 is rotatably connected to a first support rod 22 and a second support rod 23 on both sides. Each first support rod 22 is parallel to the corresponding second support rod 23. The other end of each first support rod 22 and second support rod 23 is rotatably connected to the inner wall of the cabin 1. The first support rod 22 and the second support rod 23 can drive the door 21 to move by rotation, thereby realizing the opening and closing of the door 21.

[0023] Please see Figure 3 The cabin 1 is equipped with two first drive bars 19. Each first drive bar 19 is rotatably connected to a first link 20 at both ends. The other end of each first link 20 is rotatably connected to the middle section of the corresponding first support rod 22. The first drive bar 19 can drive the first support rod 22 to rotate through the first link 20.

[0024] Please see Figure 3 A first motor is fixedly installed inside the cabin 1. A first screw 15 is fixedly connected to the output end of the first motor. The outer surface of the first screw 15 is provided with a bidirectional thread. Both ends of the first screw 15 are fixedly connected to the interior of the cabin 1.

The outer surface of the first limit rod 16 is slidably connected to the interior of the first drive bar 19, thereby supporting the first drive bar 19. The first screw 15 drives the two first drive bars 19 to move towards each other along the first limit rods 16 by rotation.

[0025] The implementation principle of an automatic take-off and landing platform for UAVs used for site analysis in this application embodiment is as follows: The second motor is started, and its output drives the second screw 17 to rotate. The second screw 17 drives two second drive bars 24 to slide. The second drive bars 24 drive the landing platform 2 to rise via the second connecting rod 25, controlling the UAV body 3 to land on the upper surface of the landing platform 2. The drive motor is then started, driving the third gear 14 to rotate. The third gear 14 drives the first gear 12 and the second gear 13 to rotate. The first gear 12 and the second gear 13 respectively drive the corresponding first fixed rod 8 and second fixed rod 8. When rod 9 rotates, the first fixed rod 8 drives the clamping block 6 and clamping plate 4 to move towards each other, and the second fixed rod 9 drives the clamping bar 7 and clamping rod 10 to move towards each other, thereby clamping and fixing the landing gear of the UAV body 3. The second motor is reversed to control the landing platform 2 to fall, completing the recovery of the UAV body 3. The first motor is started, and the output end of the first motor drives the first screw 15 to rotate. The first screw 15 drives the first drive bar 19 to slide. The first drive bar 19 drives the first support rod 22 to rotate through the first connecting rod 20, so that the first support rod 22 and the second support rod 23 drive the door 21 to move through rotation, thereby achieving closure.
