Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment technology, and more specifically to a mobile take-off and landing platform for UAVs in the field. Background Technology

[0002] During takeoff and landing, the powerful winds generated by the rotors of rotary-wing drones can easily stir up debris such as sand, soil, grass, branches, and garbage from the ground, which can then land on the drone's propellers or fuselage, causing flight accidents. Therefore, rotary-wing drones operating in the field require a level platform of sufficient area to ensure safe takeoff and landing and maintain a level attitude. However, in some remote locations, manually constructing a takeoff and landing platform requires significant time, manpower, and resources, thus hindering drone field operations. Summary of the Invention

[0003] This invention provides a mobile take-off and landing platform for unmanned aerial vehicles (UAVs) that can be deployed by airdrop, thus greatly improving construction efficiency, rapidly expanding the working range of UAVs, and eliminating the need for manual construction, thus meeting the needs of field operations under some harsh conditions.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a UAV field mobile take-off and landing platform, comprising: a central support leg, the central support leg being a longitudinally arranged cylindrical structure with a turntable at the top, a first servo motor and a battery for driving the turntable inside the central support leg, and a trigger switch at the bottom; multiple support arms, each hinged around the top of the central support leg, and a second servo motor between each support arm and the central support leg; side support legs, the top ends of the side support legs hinged to the top ends of the support arms, and a connecting rod hinged between the middle of each side support leg and the outer wall of the middle of the central support leg; and a swing shaft. Multiple swing shafts are provided, each swing shaft is disposed between any two support arms, and the bottom end of the swing shaft is hinged to the edge of the turntable; multiple first wedge plates are provided, each first wedge plate is hinged to the support arm on one side; multiple second wedge plates are provided, each second wedge plate is engaged with the swing shaft on one side through a sliding bushing, and the other side of each second wedge plate is hinged to the side of the first wedge plate away from the support arm; a controller is provided, the first servo motor, the second servo motor, the battery, and the trigger switch are electrically connected to the controller.

[0005] Preferably, each of the side outriggers is equipped with a hub motor in the middle, and the outer wall of each hub motor is hinged with multiple blades; each hub motor is electrically connected to the controller, and the controller is equipped with a flight control system.

[0006] Preferably, the top surfaces of the first wedge plate and the second wedge plate are respectively provided with photovoltaic panels, and each of the photovoltaic panels is electrically connected to the battery through a charging module; the turntable is provided with a wireless charging coil, and the wireless charging coil is electrically connected to the battery through a charging circuit.

[0007] Preferably, the central support leg is equipped with a signal repeater, which is electrically connected to the controller, and the controller is equipped with a wireless communication module.

[0008] Preferably, each of the side legs is provided with drill rods arranged side by side, and the top of each drill rod is connected to the outer wall of the hub motor housing via gears and gear rings.

[0009] Preferably, it also includes an umbrella compartment, the bottom of which is provided with an electromagnetic locking clamp that cooperates with the top of the support arm, and the top of the umbrella compartment is provided with an umbrella bag and an umbrella opener; the top center of the turntable is provided with a control socket, and the electromagnetic locking clamp and the umbrella opener are electrically connected to the control socket through cable plugs; the control socket is electrically connected to the controller.

[0010] The beneficial effects of this invention are as follows: This take-off and landing platform can be used for low-altitude deployment. In its folded state, the main control components are integrated within the relatively robust central support leg, forming the warhead structure. The folded and joined support arms and side legs form the warhead body. The mutually folded first and second wedge plates form the wing structure, ensuring the warhead's flight attitude during airdrop. Because this unmanned platform can be deployed via airdrop, construction efficiency is greatly improved, the working range of the UAV can be rapidly expanded, and manual construction is unnecessary, meeting the needs of field operations under harsh conditions. When the take-off and landing platform needs to be moved, the controller activates the first servo motor to rotate the turntable, causing the first and second wedge plates to fold and merge, thereby reducing the projected area. At this time, the controller controls the various hub motors through the flight control system, enabling it to form a multi-rotor aircraft to complete the flight movement task of the take-off and landing platform. Upon reaching the target location, the controller again uses the first servo motor to unfold the first and second wedge plates, forming the complete take-off and landing platform structure. The take-off and landing platform charges its batteries via photovoltaic panels, ensuring its own power supply. Simultaneously, it wirelessly charges drones via wireless charging coils and utilizes signal repeaters to extend network coverage, enabling drones to move between multiple platforms. The controller rotates the hub motors at low speed, driving the drill rods to anchor to the ground, improving the platform's stability. To accommodate flight migration, the rotation direction of each drill rod is opposite to the blade rotation direction, allowing the drill rods to automatically detach from the ground during migration. During high-altitude deployment, the controller sequentially triggers the parachute deployer and electromagnetic locking mechanism based on the descent altitude, executing parachute deployment and disengagement actions to meet high-altitude deployment requirements and prevent damage to the platform from high-speed impacts.

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a mobile take-off and landing platform for unmanned aerial vehicles (UAVs) includes: a central support leg 1, which is a longitudinally arranged cylindrical structure with a turntable 2 at the top. The central support leg 1 contains a first servo motor and a battery for driving the turntable 2, and a trigger switch 3 at the bottom; multiple support arms 4, each hinged around the top of the central support leg 1, with a second servo motor between each support arm 4 and the central support leg 1; side support legs 5, the top of each side support leg 5 hinged to the top of the support arm 4, and a connecting rod 6 hinged between the middle of each side support leg 5 and the outer wall of the middle section of the central support leg 1; and multiple swing shafts 7. Each of the aforementioned swing shafts 7 is disposed between any two of the aforementioned support arms 4, and the bottom end of the swing shaft 7 is hinged to the edge of the turntable 2; a first wedge plate 8, wherein multiple first wedge plates 8 are disposed, each first wedge plate 8 is hinged to the support arm 4 on one side; a second wedge plate 9, wherein multiple second wedge plates 9 are disposed, each second wedge plate 9 is engaged with the swing shaft 7 on one side via a sliding bushing 10, and the other side of each second wedge plate 9 is hinged to the side of the first wedge plate 8 away from the support arm 4; a controller, wherein the first servo motor, the second servo motor, the battery, and the trigger switch 3 are electrically connected to the controller.

[0022] Through the above design, this take-off and landing platform can be used for low-altitude deployment. In its stout state, the main control components are integrated within the relatively thick central support leg 1, forming the warhead structure. The folded and joined support arms 4 and side support legs 5 form the warhead body. The mutually folded first wedge plate 8 and second wedge plate 9 form the wing structure, ensuring the warhead's flight attitude during airdrop. During airdrop deployment, the central support leg 1 touches the ground vertically. After receiving a signal from the trigger switch 3, the controller activates the second servo motor, causing each support arm 4 to rapidly deploy. The side outriggers 5 remain vertical under the action of the connecting rod 6 until all the support arms 4 are tilted down to a horizontal position. At this point, the side outriggers 5 and the central outrigger 1 together form a support structure, providing stable support to both ends of each support arm 4. Subsequently, the controller activates the second servo motor, causing the turntable 2 to drive the swing shaft 7 to rotate. This causes the swing shaft 7, which was originally parallel to one adjacent support arm 4, to sweep towards another adjacent support arm 4. During the sweeping process, the second wedge plate 9 drags the first wedge plate 8 to unfold, forming the plane of the take-off and landing platform. Because this unmanned platform can be deployed by airdrop, it greatly improves construction efficiency, can quickly expand the working range of the UAV, and does not require manual construction, meeting the needs of field operations under some harsh conditions.

[0023] Each of the side outriggers 5 is fitted with a hub motor 11 in the middle, and the outer wall of each hub motor 11 is hinged with a plurality of blades 12; each hub motor 11 is electrically connected to the controller, and the controller is equipped with a flight control system.

[0024] With this setup, when the take-off and landing platform needs to be moved, the controller starts the first servo motor to rotate the turntable 2 and folds the first wedge plate 8 and the second wedge plate 9 together, thereby reducing the projected area. At this time, the controller controls each hub motor 11 to work through the flight control system, so that it can form a multi-rotor aircraft to complete the flight movement task of the take-off and landing platform. When the target location is reached, the controller once again uses the first servo motor to unfold the first wedge plate 8 and the second wedge plate 9 to form a complete take-off and landing platform structure.

[0025] The top surfaces of the first wedge plate 8 and the second wedge plate 9 are respectively provided with photovoltaic panels 13, and each photovoltaic panel 13 is electrically connected to the battery through a charging module; the turntable 2 is provided with a wireless charging coil 21, which is electrically connected to the battery through a charging circuit. In addition, a signal repeater is provided inside the central support leg 1, which is electrically connected to the controller, and the controller is provided with a wireless communication module.

[0026] In this setup, the take-off and landing platform charges the battery through the photovoltaic panel 13, thus ensuring its own power supply needs. At the same time, it wirelessly charges the drone through the wireless charging coil 21 and uses a signal repeater to extend the network coverage, enabling the drone to move and fly between multiple take-off and landing platforms.

[0027] Each of the side support legs 5 is provided with drill rods 14 arranged side by side, and the top of each drill rod 14 is connected to the outer wall of the hub motor housing 11 through gears and gear rings.

[0028] In this setup, the controller causes the hub motor 11 to rotate at a low speed, thereby driving the drill rod 14 to anchor to the ground and improve the stability of the take-off and landing platform. At the same time, in order to meet the needs of flight migration, the rotation direction of each drill rod 14 is opposite to the rotation direction of the blade 12 during flight migration. Therefore, the drill rod 14 can automatically exit the ground during flight migration.

[0029] It also includes an umbrella compartment 15, the bottom of which is provided with an electromagnetic locking clip 17 that cooperates with the top of the support arm 4, and the top of the umbrella compartment 15 is provided with an umbrella bag 18 and an umbrella opener 19; the top center of the turntable 2 is provided with a control socket 16, and the electromagnetic locking clip 17 and the umbrella opener 19 are electrically connected to the control socket 16 through cable plugs 20; the control socket 16 is electrically connected to the controller.

[0030] Through the above design, during the high-altitude deployment process, the controller triggers the parachute opener 19 and the electromagnetic locking clamp sequentially according to the descent altitude to perform parachute opening and disengagement actions, meeting the high-altitude deployment requirements and avoiding damage to the deployment platform caused by high-speed impact.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
