Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle equipment, and in particular to a field mobile take-off and landing platform for an unmanned aerial vehicle. Background Art

[0002] The huge wind force generated by the rotors of rotary-wing drones during takeoff and landing can easily roll up sand, soil, grass, branches, garbage and other debris on the ground, which can reach the blades or fuselage of the drone and cause flight accidents. Therefore, when operating in the field, rotary-wing drones require a horizontal platform with a certain area to ensure the takeoff and landing process of the drone and to ensure that the attitude is level. However, in some remote geographical locations, it takes a lot of time, manpower and material resources to manually build a take-off and landing platform, which causes inconvenience to the drone's field flight missions. Summary of the invention

[0003] The present invention provides a field mobile take-off and landing platform for unmanned aerial vehicles, which can be placed by airdrop, thereby greatly improving the construction efficiency, rapidly expanding the working range of the unmanned aerial vehicle, and meeting the needs of field operations under some harsh conditions without the need for manual construction.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a field mobile take-off and landing platform for unmanned aerial vehicles, comprising: a central leg, the central leg is a longitudinal cylindrical structure, a turntable is provided on the top, a first servo motor and a battery for driving the turntable are provided inside the central leg, and a trigger switch is provided at the bottom; a supporting arm, the supporting arm is provided in multiple arrangements and is respectively hinged around the top of the central leg, and a second servo motor is provided between each of the supporting arms and the central leg; a side leg, the top of the side leg is hingedly matched with the top of the supporting arm, and a connecting rod is hingedly connected between the middle of each side leg and the outer wall of the middle of the central leg; a swing shaft, the There are multiple settings for the pendulum shaft, each of which is set between any two of the support arms, and the bottom end of the pendulum shaft is hingedly matched with the edge of the turntable; there are multiple settings for the first wedge plates, and each of the first wedge plates is hingedly matched with the support arm through one side; there are multiple settings for the second wedge plates, and each of the second wedge plates is hingedly matched with the pendulum shaft through one side through a sliding sleeve, and the other side of each of the second wedge plates is hingedly matched with the side of the first wedge plate away from the support arm; a controller, the first servo motor, the second servo motor, the battery and the trigger switch are electrically connected to the controller respectively.

[0005] Preferably, a hub motor is respectively mounted in the middle of each of the side legs, and a plurality of blades are respectively hinged on the outer wall of each of the hub motors; each of the hub motors is respectively electrically connected to the controller, and a flight control system is arranged in the controller.

[0006] Preferably, photovoltaic panels are respectively provided on the top surfaces of the first wedge plate and the second wedge plate, 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, a signal repeater is provided inside the central leg, the signal repeater is electrically connected to the controller, and the controller is provided with a wireless communication module.

[0008] Preferably, drill rods are arranged in parallel outside each of the side legs, and the top end of each of the drill rods is connected to the outer wall of the hub motor housing through a gear and a gear ring.

[0009] Preferably, it also includes a parachute bin, the bottom of which is provided with an electromagnetic locking clip cooperating with the top of each of the support arms, and the top of which is provided with a parachute bag and a parachute opener; a control socket is provided in the center of the top of the turntable, and the electromagnetic locking clip and the parachute opener are electrically connected to the control socket through a cable plug respectively; and the control socket is electrically connected to the controller.

[0010] The beneficial effects of the present invention are as follows: the take-off and landing platform can be used for low-altitude placement, the relatively sturdy central leg in the storage state integrates the main control components and constitutes the warhead structure, while the folded support arm and the side leg constitute the warhead body, and the mutually folded first wedge plate and the second wedge plate constitute the fixed wind wing structure to ensure the flight posture of the warhead during the airdrop process. Since the unmanned platform can be placed by airdrop, the construction efficiency is greatly improved, the working range of the unmanned aerial vehicle can be quickly expanded, and no manual construction is required, which meets the field operation requirements under some harsh conditions. When the take-off and landing platform needs to be relocated, the controller starts the first servo motor to rotate the turntable, and folds and merges the first wedge plate and the second wedge plate, thereby reducing the projected area. At this time, the controller controls the operation of each hub motor through the flight control system, so that it constitutes a multi-axis aircraft to complete the flight movement task of the take-off and landing platform. When arriving at the target location, the controller again unfolds the first wedge plate and the second wedge plate through the first servo motor to form a complete take-off and landing platform structure. The landing platform charges the battery through photovoltaic panels to ensure its own power supply needs. At the same time, it also wirelessly charges the drone through a wireless charging coil and uses a signal repeater to expand the network coverage to meet the needs of drones to move between multiple landing platforms. The controller makes the hub motor rotate at a low speed, thereby driving the drill rod to anchor to the ground and improve the stability of the landing platform. At the same time, in order to meet the needs of flight migration, the rotation direction of each drill rod is opposite to the rotation direction of the blade flight. Therefore, during the flight migration process, the drill rod can automatically withdraw from the ground. During the high-altitude delivery of the landing platform, the controller triggers the parachute opener and electromagnetic lock clamp in sequence according to the descent height to perform the parachute opening and parachute removal actions, meet the needs of high-altitude delivery, and avoid damage to the landing platform caused by high-speed impact.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 field mobile take-off and landing platform for unmanned aerial vehicles comprises: a central leg 1, which is a longitudinal cylindrical structure, with a turntable 2 on the top, a first servo motor and a battery for driving the turntable 2 inside the central leg 1, and a trigger switch 3 at the bottom; a support arm 4, which is provided in multiples and is respectively hinged around the top of the central leg 1, and a second servo motor is provided between each of the support arms 4 and the central leg 1; a side leg 5, the top of the side leg 5 is hinged to the top of the support arm 4, and a connecting rod 6 is hinged between the middle of each side leg 5 and the outer wall of the middle of the central leg 1; a swing shaft 7, which is provided in multiples, each swing shaft 7 has a connecting rod 6, and ... Each of the swing shafts 7 is arranged between any two of the support arms 4, and the bottom end of the swing shaft 7 is hingedly matched with the edge of the turntable 2; a first wedge plate 8, the first wedge plate 8 is arranged in multiples, and each of the first wedge plates 8 is hingedly matched with the support arm 4 through one side; a second wedge plate 9, the second wedge plate 9 is arranged in multiples, and each of the second wedge plates 9 is matched with the swing shaft 7 through a sliding sleeve 10 on one side, and the other side of each of the second wedge plates 9 is hingedly matched with the side of the first wedge plate 8 away from the support arm 4; a controller, the first servo motor, the second servo motor, the battery and the trigger switch 3 are electrically connected to the controller respectively.

[0022] Through the above design, the take-off and landing platform can be used for low-altitude delivery and placement. The relatively sturdy central leg 1 in the stored state integrates the main control components and constitutes the warhead structure, while the folded support arm 4 and the side leg 5 constitute the warhead body, and the mutually folded first wedge plate 8 and second wedge plate 9 constitute the fixed wind wing structure to ensure the flight posture of the warhead during the airdrop process. During the airdrop placement process, the central leg 1 touches the ground vertically, and the controller starts the second servo motor after receiving the signal of the trigger switch 3, so that each support arm 4 is quickly unfolded. The side legs 5 are always kept in a vertical state under the action of the connecting rod 6 until each support arm 4 turns down to a horizontal state. At this time, the side legs 5 and the central leg 1 together form a support structure to provide stable support force for both ends of each support arm 4. Then the controller starts the second servo motor to make the turntable 2 drive the swing shaft 7 to rotate, so that the swing shaft 7 originally parallel to an adjacent support arm 4 sweeps toward another adjacent support arm 4. During the sweeping process, the second wedge plate 9 drags the first wedge plate 8 to unfold and form the plane of the take-off and landing platform. Since the unmanned platform can be placed by airdrop, it greatly improves the construction efficiency, can quickly expand the working range of the drone, and does not require manual construction, meeting the needs of field operations under some harsh conditions.

[0023] A hub motor 11 is respectively sleeved on the middle part of each of the side legs 5, and a plurality of blades 12 are respectively hinged on the outer wall of each of the hub motors 11; each of the hub motors 11 is respectively electrically connected to the controller, and a flight control system is arranged inside the controller.

[0024] Through this arrangement, when the take-off and landing platform needs to be relocated, the controller starts the first servo motor to rotate the turntable 2, and folds and merges the first wedge plate 8 and the second wedge plate 9, thereby reducing the projected area. At this time, the controller controls the operation of each hub motor 11 through the flight control system, so that it constitutes a multi-axis aircraft to complete the flight movement task of the take-off and landing platform. When arriving at the target location, the controller 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 of the photovoltaic panels 13 is electrically connected to the battery through a charging module; the turntable 2 is provided with a wireless charging coil 21, and the wireless charging coil 21 is electrically connected to the battery through a charging circuit. In addition, a signal repeater is provided inside the central leg 1, and the signal repeater is electrically connected to the controller, and the controller is provided with a wireless communication module.

[0026] In this setting, the landing platform charges the battery through the photovoltaic panel 13 to ensure its own power supply needs. At the same time, it also wirelessly charges the drone through the wireless charging coil 21 and uses the signal repeater to expand the network coverage to meet the needs of the drone to move and fly between multiple landing platforms.

[0027] Drill rods 14 are arranged in parallel outside each of the side legs 5 , and the top end of each of the drill rods 14 is connected to the outer wall of the housing of the hub motor 11 through a gear and a gear ring.

[0028] In this setting, the controller causes the hub motor 11 to rotate at a low speed, thereby driving the drill rod 14 to anchor to the ground, improving 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 flight rotation direction of the blade 12. Therefore, during the flight migration process, the drill rod 14 can automatically withdraw from the ground.

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

[0030] Through the above design, during the high-altitude drop process of the take-off and landing platform, the controller triggers the parachute opener 19 and the electromagnetic locking clamp in sequence according to the descent height to perform the parachute opening and parachute removal actions, thereby meeting the high-altitude drop requirements and avoiding damage to the take-off and landing platform caused by high-speed impact.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
