Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) take-off and landing airport technology, specifically a mobile and portable UAV take-off and landing airport. Background Technology

[0002] With the rapid development of drone technology, mobile portable drone take-off and landing airports, as important supporting equipment for drone operations, have evolved from a single take-off and landing platform to integration, intelligence, and high security.

[0003] An existing patent (publication number: CN221091288U) discloses a portable drone landing pad, comprising two rectangular, hollow internal device boxes connected by multiple hinges. This portable drone landing pad, by incorporating multiple device tubes and multiple fixing pins, allows the two boxes to be opened and rotated to form a flat surface when a drone needs to land. The multiple device tubes are then pulled down and rotated until they contact a limiting block, forming multiple outwardly extending support legs. The extension length of the multiple threaded rods can then be adjusted by rotating multiple threaded sleeves according to the actual landing site, ensuring the landing surface remains level. The device can then be placed on the ground to land the drone, enabling safe and convenient drone landing or takeoff even in the field, thus improving the device's practicality.

[0004] The aforementioned drone take-off and landing airfield can adjust the extension length of multiple threaded rods by rotating multiple threaded sleeves according to the actual conditions of the landing site, ensuring that the landing plane of the device can always remain horizontal. Then, the device can be placed on the ground to land the drone. However, it is not convenient to store the drone during transport. In the prior art, the landing platform of the drone take-off and landing airfield with storage function has a V-shaped cross section. After landing, the drone can be guided into the slot. However, during the closing process of the cover, due to the vibration generated when the drone lands, it will shift along the axis of the V-shaped slot. Especially in complex terrain or windy conditions, it is difficult to guarantee the accuracy of the drone's landing position. During the closing process of the cover, the drone's propellers and shell are easily squeezed, which can easily cause equipment damage. Secondly, during transport, the drone is prone to collision with the cover wall and slot wall in the case of shaking. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a mobile and portable drone take-off and landing airport, which has advantages such as assisted homing and stable fixation, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a mobile portable drone take-off and landing airport, including a chassis, a protective cover symmetrically arranged on the top of the chassis, and a platform installed on the top of the chassis. The upper surface of the platform has two sliding grooves arranged along its length direction. The two sliding grooves are symmetrically arranged, and a fixing component is provided above each of the two sliding grooves for fixing the drone. A drive mechanism is installed in each of the two slides to drive the two fixed components to move closer or further apart. The fixing component includes a clamping plate arranged along the width direction of the platform. One side of the clamping plate is provided with a clamping groove arranged along its length direction. Two symmetrically arranged sliders are slidably connected to the clamping groove. The two sliders are rotatably connected to a locking shaft along their height direction. An arc-shaped rod is fixedly connected to the outer surface of the locking shaft. The fixing component also includes a linear module, which is fixedly connected to one side of the clamping plate and is arranged along the height direction of the chassis. A pressure plate is slidably connected to one side of the linear module along its height direction.

[0007] Furthermore, the chassis has two symmetrically arranged closed shafts rotatably connected inside its width direction. The two ends of the two closed shafts are respectively fixedly connected to swing arms. The top of each swing arm is fixedly connected to a protective cover close to it. Worm gears are fixedly connected to the circumferential surfaces of the two closed shafts. A dual-axis motor is fixedly installed on the inner wall of the chassis. The two output ends of the dual-axis motor are fixedly connected to worms. The two worms are respectively meshed with the worm gears close to them.

[0008] With the above solution, the dual-axis motor is the core driving component that provides bidirectional rotational power. The worm drives the worm wheel to rotate, which in turn drives the two closed shafts to move the top of the swing arm in opposite directions, thus realizing the synchronous opening and closing of the protective cover.

[0009] Furthermore, a set of universal wheels is fixedly installed at the bottom of the chassis. Self-locking slide rails are installed on the front and back of the chassis along their length. An adjusting block is slidably connected to each of the two self-locking slide rails. A plug rod is hinged to the opposite side of each of the two adjusting blocks. A sleeve block is slidably fitted onto the outer surface of each of the two plug rods along their length. A pull rod is fixedly connected between the top ends of the two sleeve blocks.

[0010] The above solution allows users to easily pull the case. During movement, even on bumpy roads, the fixing components maintain the stability of the drone through multi-directional limiting. Secondly, when the case needs to be reversed, the user can move the plug rod from the self-locking slide rail to the other end to change the direction of the pull.

[0011] Furthermore, the outer surfaces of both insert rods and sleeve blocks are provided with a set of linearly and equally spaced threaded holes along their length direction, and each insert rod is fixedly connected to its adjacent sleeve block by bolts.

[0012] The above solution enables the adjustment of the pull rod height, making it convenient for users of different heights. The pull rod height can be locked by fixing the bolt to the threaded hole at the corresponding position on the sleeve block.

[0013] Furthermore, the driving mechanism includes a bidirectional lead screw, with both ends of the bidirectional lead screw rotatably connected to the inner walls of two slides respectively. A first bevel gear is fixedly connected to the middle end of the bidirectional lead screw. A motor is fixedly installed on the inner wall of the platform. A power shaft is fixedly connected to the output end of the motor. A second bevel gear is fixedly connected to the output end of the power shaft. The first bevel gear and the second bevel gear are meshed together.

[0014] The above solution enables the two clamps to move synchronously towards or away from each other along the length of the platform, thus adapting to the fixing requirements of drones of different sizes.

[0015] Furthermore, a bidirectional threaded rod is rotatably connected between both ends of the two clamping plates, and each slider is threaded to one end of its corresponding bidirectional threaded rod.

[0016] The above scheme uses a rotating bidirectional threaded rod to drive two sliders to move synchronously towards or away from each other, adjusting the spacing between the arc-shaped rods to match the width of the drone's support legs.

[0017] Furthermore, a set of electric actuators arranged in a matrix are installed on both sides of the chassis. The set of electric actuators is set along the height direction of the chassis, and the output end of each set of electric actuators is fixedly connected to the chassis. A level sensor is installed at the bottom of the chassis.

[0018] The above solution enables automatic leveling in complex terrain, ensuring that the UAV take-off and landing platform is always in a horizontal position.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This mobile and portable drone take-off and landing airport achieves the drone's X-axis positioning on the platform through the opposing movement of clamping plates, and the symmetrical clamping of the arc-shaped rod achieves centering in the Y-axis direction. With the Z-axis pressing and limiting of the pressure plate, a centering limit is formed after the drone lands. After limiting, the outriggers of the drone can be locked and fixed by rotating the arc-shaped rod. This solves the problem of axial displacement caused by drone landing vibration in traditional take-off and landing platforms, avoids the risk of propeller squeezing during the closing of the protective cover, and effectively suppresses equipment shaking during movement and transfer, significantly improving the structural safety of the drone during transport. The matrix-style electric actuators and level sensors installed in the chassis can detect the platform's tilt angle and automatically extend and level it, ensuring the levelness of the take-off and landing plane in uneven terrain. This solves the problem of time-consuming and laborious traditional manual leveling. The omnidirectional wheels, combined with the reversible pull rod design, enable the equipment to turn flexibly in narrow spaces. The height adjustment structure of the plug and sleeve blocks improves the operating comfort of users of different heights, and the overall equipment enhances its site adaptability and ease of movement.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-7 This embodiment of a mobile portable drone take-off and landing airport includes a chassis 1, a protective cover 2 symmetrically arranged on the top of the chassis 1, and a platform 3 installed on the top of the chassis 1. The upper surface of the platform 3 has two sliding grooves 301 arranged along its length direction. The two sliding grooves 301 are symmetrically arranged, and a fixing component 4 is provided above each of the two sliding grooves 301 for fixing the drone.

[0024] Inside the casing 1, two symmetrically arranged closed shafts 6 are rotatably connected along its width. Each end of the two closed shafts 6 is fixedly connected to a swing arm 7. The top of each swing arm 7 is fixedly connected to a protective cover 2 adjacent to it. Worm gears 8 are fixedly connected to the circumference of both closed shafts 6. A dual-axis motor 9 is fixedly installed on the inner wall of the casing 1. Worms 10 are fixedly connected to both output ends of the dual-axis motor 9. The two worm gears 10 are meshed with the worm gears 8 adjacent to them. The dual-axis motor 9 is the core driving component providing bidirectional rotational power. The worm gears 10 drive the worm gears 8 to rotate, thereby driving the two closed shafts 6 to move the tops of the swing arms 7 towards and away from each other, achieving synchronous opening and closing of the protective cover 2.

[0025] A drive mechanism 5 is installed in each of the two sliding grooves 301 to drive the two fixed components 4 to move closer or further apart. The fixed component 4 includes a clamping plate 401 arranged along the width direction of the platform 3. One side of the clamping plate 401 has a clamping groove 402 arranged along its length direction. The clamping groove 402 is slidably connected to two symmetrically arranged sliders 403. The two sliders 403 are rotatably connected to a locking shaft 404 along their height direction. The top end of each locking shaft 404 is fixedly connected to the output end of an external power source. An arc-shaped rod 405 is fixedly connected to the outer surface of the locking shaft 404. When the drone lands on the platform 3, due to the impact force during landing, the drone will vibrate due to the landing impact, causing axial displacement. During the closing process of the protective cover 2, the drone's propellers and structure are easily squeezed. This fixed component 4 can prevent the drone from landing. First, the two clamping plates 401 are closed. 01 The two plates approach each other, contact the four support legs of the drone and push them, then push them to the middle of the length direction of platform 3. Then the arc rods 405 approach each other, contact the four support legs of the drone and push them to the middle of the width direction of the chassis 1, achieving precise positioning of the drone. Next, the external power source drives the locking shaft 404 to rotate, and the arc rods 405 flip to lock the support legs, limiting the movement of the drone in the X and Y axes. Both ends of the two clamping plates 401 are rotatably connected to the two bidirectional threaded rods 408. Each slider 403 is threaded to one end of its corresponding bidirectional threaded rod 408. One end of the bidirectional threaded rod 408 is fixedly connected to the output end of the external power source. Rotating the bidirectional threaded rods 408 drives the two sliders 403 to move synchronously towards or away from each other, and the spacing of the arc rods 405 is adjusted to match the width of the drone support legs.

[0026] The drive mechanism 5 includes a bidirectional lead screw 501, with both ends of the bidirectional lead screw 501 rotatably connected to the inner walls of two sliding grooves 301 respectively. A first bevel gear 502 is fixedly connected to the middle end of the bidirectional lead screw 501. A motor 503 is fixedly installed on the inner wall of the platform 3. A power shaft 504 is fixedly connected to the output end of the motor 503. A second bevel gear 505 is fixedly connected to the output end of the power shaft 504. The first bevel gear 502 and the second bevel gear 505 mesh with each other, enabling the two clamping plates 401 to move synchronously towards or away from each other along the length of the platform 3, in order to adapt to the fixing requirements of UAVs of different sizes. The fixing component 4 also includes a straight... Line module 406 is fixedly connected to one side of clamping plate 401 and set along the height direction of chassis 1. One side of linear module 406 is slidably connected to pressure plate 407 along its height direction. When arc rod 405 locks the support leg, pressure plate 407 can press on the upper surface of the drone and limit its Z-axis, which further improves the stability when fixed and prevents the drone from shaking on chassis 1 and colliding with the inner wall of protective cover 2 during movement, making it easier to carry and transfer as a whole. Fixing component 4 is linked through external PLC controller. After the X / Y axis returns to position, the Z-axis pressing is triggered, and finally the locking action is performed.

[0027] A set of casters 11 is fixedly installed at the bottom of the chassis 1. Self-locking slide rails 12, extending along their length, are installed on both the front and back of the chassis 1. Each of the two self-locking slide rails 12 is slidably connected to an adjusting block 13. Insert rods 14 are hinged to the opposite sides of each adjusting block 13. Sleeves 15 are slidably fitted onto the outer surfaces of each insert rod 14 along their length. A pull rod 16 is fixedly connected between the tops of the two sleeves 15. This design facilitates the user's pulling of the chassis 1. Even when encountering bumpy terrain during movement, the fixing assembly 4 provides multi-directional limiting protection. The drone is held stably. Secondly, when the chassis 1 needs to be turned around, the user can pull it in a different direction by moving the plug rod 14 from the self-locking slide rail 12 to the other end. The outer surfaces of the two plug rods 14 and the sleeve block 15 are provided with a set of linearly and equally spaced threaded holes 17 along their length. Each plug rod 14 is fixedly connected to the sleeve block 15 next to it by bolts, which can realize the purpose of adjusting the height of the pull rod 16, making it convenient for users of different heights to use. The height of the pull rod 16 can be locked by fixing the corresponding threaded holes 17 on the plug rod 14 and the sleeve block 15 with bolts.

[0028] A set of electric actuators 18 arranged in a matrix is ​​installed on both sides of the chassis 1. One set of electric actuators 18 is set along the height direction of the chassis 1. The output end of each set of electric actuators 18 is fixedly connected to the chassis 19. A level sensor 20 is installed at the bottom of the chassis 1. The level sensor 20 and the electric actuators 18 are connected to the external control system. The control logic is that when the level sensor 20 detects that the platform 3 is tilted, the control system starts the extension and retraction of the electric actuators 18 on the corresponding side, adjusting the height of the chassis 19 until the platform 3 returns to a level state. Specifically, the level sensor 20 collects the tilt angle data of the X-axis and Y-axis of the platform 3 in real time and transmits it to the control system. When the X-axis tilts in the positive direction, it drives the two sets of electric actuators 18 on the front to extend and the two sets on the rear to shorten. When the Y-axis tilts in the negative direction, it drives the two sets of electric actuators 18 on the right to shorten and the two sets on the left to extend. When there is a compound tilt, the four sets of electric actuators 18 are adjusted synchronously according to the vector superposition principle to realize the automatic leveling function in complex terrain in the field and ensure that the UAV take-off and landing platform 3 is always in a level state.

[0029] The working principle of the above embodiment is as follows: When the drone lands on the surface of platform 3, it experiences slight vibration or axial displacement due to the impact. At this time, the protective cover 2 is in the open state to avoid interfering with the landing process. The motor 503 inside platform 3 starts, driving the second bevel gear 505 to rotate through the power shaft 504. This drives the first bevel gear 502 and the bidirectional lead screw 501 to rotate. The bidirectional lead screw 501 drives the two side clamping plates 401 to move towards each other along the slide groove 301, moving from both ends of the platform 3 towards the center, pushing the drone support legs to the longitudinal centerline of platform 3, achieving precise positioning in the X-axis direction. An external power source rotates the bidirectional lead screws at both ends of the clamping plates 401. The grooved rod 408 drives the two sliders 403 in the clamping groove 402 to move synchronously towards each other, adjusts the spacing of the arc rods 405 and pushes the drone closer to the center of the platform 3, completing the centering in the Y-axis direction. The external power source drives the locking shaft 404 to rotate, causing the arc rods 405 to flip, so that their arc surfaces fit against the outside of the support legs, forming a mechanical locking structure to prevent the X / Y axis from sliding. The linear module 406 is activated, driving the pressure plate 407 to descend along the height direction of the chassis 1, pressing on the upper surface of the drone, limiting the jump in the Z-axis direction, and achieving omnidirectional fixation.

[0030] Subsequently, the dual-axis motor 9 starts, driving the worm gears 10 at both ends to rotate. Through the meshing worm wheel 8, the closed shaft 6 rotates. The closed shaft 6 is connected to the protective cover 2 through the swing arm 7. The two swing arms 7 rotate inward synchronously, causing the protective cover 2 to close smoothly in the form of a "double door". Since the drone is located in the center of the platform 3, it can avoid squeezing the fixed drone propellers or structure during the closing of the protective cover 2. When the dual-axis motor 9 reverses, the worm gear 10 drives the worm wheel 8 to rotate in the opposite direction, and the swing arm 7 unfolds outward. The protective cover 2 is fully opened to a vertical state, providing unobstructed space for the drone to take off and land.

[0031] When overall movement is required, the user pulls the housing 1 via the lever 16, and the casters 11 provide multi-directional rolling capability. When reversing direction is required, the insert rod 14 is moved to the other end along the self-locking slide rail 12 to reverse the direction of the lever 16, adapting to the turning needs in narrow spaces. The insert rod 14 and the sleeve block 15 are height-adjustable via the threaded hole 17 to accommodate users of different heights. When deploying platform 3, the level sensor 20 monitors the X / Y axis tilt angle of platform 3 in real time, and the data is transmitted to the control system. The control system calculates and adjusts the strategy according to the tilt vector, driving the corresponding electric actuators 18 to extend and retract. When tilting in the positive direction of the X axis, the front electric actuator 18 extends and the rear one shortens. When tilting in the negative direction of the Y axis, the right electric actuator 18 shortens and the left one extends. When tilting in a compound manner, the four sets of electric actuators 18 are adjusted synchronously according to the principle of vector superposition until platform 3 returns to a horizontal state.
