A vehicle-mounted external drone airport

Abstract

This invention discloses a vehicle-mounted external drone airport, relating to the technical field of drone parking equipment. It includes a mounting plate on which a frame is fixedly mounted. A holding trough is fixedly mounted on the top of the frame, and a floating trough is movably mounted on the holding trough. A placement plate is mounted on the top of the floating trough. The frame and the floating trough are connected by a swinging connection. A rubber edging is fixedly installed between the edge of the floating trough and the inner wall of the holding trough. In this vehicle-mounted external drone airport, when the vehicle is tilted, the liquid inside the holding trough automatically levels itself, causing the floating trough to level itself on the fluid surface. Therefore, the floating trough follows the fluid and remains perpendicular to the Earth's center, allowing it to automatically level itself within the holding trough for convenient drone parking upon return. In this structure, the swinging trough engages with a sealing spherical body to prevent the floating trough from tearing or damaging parts of the structure due to inertial impact.

Description

Technical Field

[0001] This invention relates to the field of drone parking equipment technology, specifically a vehicle-mounted external drone parking facility. Background Technology

[0002] Vehicle-mounted landing and securing platforms for rotary-wing unmanned aerial vehicles (UAVs) have always been a hot topic in both military and civilian UAV applications. Using these platforms to mount UAVs allows for rapid battlefield reconnaissance or enables UAVs to take off freely and be secured after landing in civilian applications. To ensure flexible takeoff and landing and ease of use of vehicle-mounted platforms, research on UAV vehicle-mounted platforms mainly focuses on how to quickly and easily install the platform on a vehicle, how to quickly remove water accumulation on the platform, how to eliminate the impact of backflow air on UAV landing, and how to secure the UAV on a high-speed moving vehicle and how to flexibly deploy and release it during takeoff.

[0003] In the early stages, drones were used for various applications such as inspections, forest fire prevention, pesticide spraying, and video recording. However, manual maintenance was inefficient and costly, which led to the development of vehicle-mounted drone airports.

[0004] When in the field, vehicles may be tilted when road conditions are uncertain. In most cases, the fixed platform of a vehicle-mounted drone airport is usually fixed to the vehicle frame, which will affect the landing error of the drone in the center of the recovery platform during automatic recovery, making it impossible for the drone to stop in the center of the recovery platform. In rainy weather, if the vehicle is tilted too much, the drone may slip on the ground and cause a "drone crash". To address this, we propose a vehicle-mounted external drone airport. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted external unmanned airport to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted external unmanned aerial vehicle (UAV) airport, comprising a mounting plate, a frame fixedly mounted on the mounting plate, a holding trough fixedly mounted on the top of the frame, a floating trough movably mounted on the holding trough, a placement plate mounted on the top of the floating trough, the frame and the floating trough being connected together by a swinging connection, a rubber edging being fixedly installed between the edge of the floating trough and the inner wall of the holding trough, a diagonal block being fixedly installed at each corner inside the floating trough, a second motor being fixedly installed on one side of each diagonal block, multiple diagonal blocks and multiple second motors forming a rectangle, a second optical axis being connected between each diagonal block and the second motor on the same side, a slider being slidably connected on the second optical axis, a fastening strip being fixedly installed on each slider, and the slider being moved on the second optical axis by belt transmission.

[0007] Preferably, an extension rod is installed vertically in the middle of the frame, a sealing sphere is installed at the top of the extension rod, and a swing groove is installed in the middle of the bottom of the floating trough. The swing groove engages with the sealing sphere to cause the floating trough to swing randomly.

[0008] Preferably, each of the two parallel fastening strips has a protrusion fixedly installed in the middle, and each protrusion has a lever rotatably connected to both ends. A fixed cylinder is fixedly installed at one end of the lever, and a second spring is fixedly connected to the bottom of the fixed cylinder. A pressure ring is connected to the bottom of the second spring, and a miniature electric telescopic rod is fixedly installed at the other end of the lever. The miniature electric telescopic rod is fixedly connected to the protrusion.

[0009] Preferably, each side of the floating trough is fixedly equipped with a bearing, a first spring is connected between the inner ring of the bearing and the holding trough, and the bottom of the floating trough is rounded.

[0010] Preferably, a cooling cylinder is fixedly installed at each corner of the holding tank, and a pressure stabilizing hole is opened at the bottom of each cooling cylinder. A ball rod is rotatably connected to one side of the bottom of the pressure stabilizing hole, and a hollow ball is fixedly connected to the side of the ball rod facing the holding tank. A through plate is fixedly installed inside the cooling cylinder, and one end of the ball rod slides in contact with the through plate. A through port for liquid outflow is opened on the surface of the through plate. A transfer cylinder is fixedly installed above the through port of the cooling cylinder, and a spiral blade is rotatably connected inside the transfer cylinder.

[0011] Preferably, at least eight cooling cylinders are provided, and each cooling cylinder has a vent hole at its top. The bottom of the spiral blade is connected to a pulley, and one end of the pulley is connected to a third motor.

[0012] Preferably, locking shafts are fixedly installed at both ends of the frame, and a first optical shaft is fixedly installed inside each locking shaft. A first motor is fixedly installed in the middle of both sides of the frame. The output shaft of the first motor is connected to a worm gear. A worm wheel is fixedly connected to the first optical shaft. Detachable hatches are installed at both ends of the locking shaft.

[0013] Preferably, the surface of the placement plate is frosted, the distance between the edge of the floating trough and the inner wall of the holding trough is 100mm, and a guide block is provided in the middle of the placement plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the vehicle body is tilted, the liquid inside the holding tank will automatically level itself, causing the floating tank to level itself on the fluid surface. Therefore, the floating tank follows the fluid and is perpendicular to the center of the earth, allowing the floating tank to automatically level itself inside the holding tank, which facilitates the drone's return and shutdown. In the relevant structure, the swinging tank engages with the sealing spherical body to prevent the floating tank from tearing and damaging part of the structure due to inertia.

[0016] This invention features a dual self-locking system when a drone is docked in a hangar, preventing the drone from shifting upwards or left or right after being vibrated on the placement plate, thus improving the stability of the equipment for the drone.

[0017] This invention utilizes the inertia of fluids to protect mechanical components to a certain extent, reduce rigid vibration contact, reduce noise, and extend structural life. At the same time, it facilitates heat exchange operations inside the hangar, improves heat dissipation, and reduces the occurrence of drone charging failures. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0030] Please see Figure 1-10This invention provides a technical solution: a vehicle-mounted external unmanned aerial vehicle (UAV) airport, including a mounting plate 1, a frame 2 fixedly mounted on the mounting plate 1, a holding trough 3 fixedly mounted on the top of the frame 2, a floating trough 4 movably mounted on the holding trough 3, a placement plate 5 mounted on the top of the floating trough 4, the frame 2 and the floating trough 4 connected by a swing connection, a rubber edging 7 fixedly mounted between the edge of the floating trough 4 and the inner wall of the holding trough 3, and a diagonal block 9 fixedly mounted at each corner inside the floating trough 4, with a second electric... The frame 10 consists of multiple diagonal blocks 9 and multiple second motors 10 arranged in a rectangle. A second optical axis 12 connects each diagonal block 9 and second motor 10 on the same side. A slider 11 is slidably connected to the second optical axis 12, and each slider 11 is fixedly mounted with a fastening strip 8. The slider 11 moves along the second optical axis 12 via a belt transmission. For the drone, this not only provides stability when it is parked, but also reduces vibration between the drone and the frame 2 during transport by vehicle, thereby improving its performance. Upon returning from the mission, if the vehicle is parked on a sloping surface, and the placement platform 5 was also tilted before modification, the drone may slip off the platform 5. During installation, sufficient fluid (such as water or other types of supercooled water) is injected into the container 3. Injection is stopped when the fluid surface contacts the bottom of the floating tank 4, causing the floating tank 4 to float on the fluid. The floating tank 4 then oscillates within the container 3. When the vehicle is tilted, the liquid inside the container 3 automatically levels itself, causing the floating tank 4 to move on the fluid surface. Leveling is achieved by ensuring the floating trough 4 contacts the fluid and remains perpendicular to the Earth's center, allowing it to automatically level within the holding tank 3. This facilitates stopping the drone upon return. Then, the second motor 10 is activated, rotating the belt at the shaft end. This causes the slider 11 to slide along the second optical axis 12. As each fastening bar 8 moves with the slider 11, the rectangular contact area formed between the multiple fastening bars 8 decreases, eventually bringing the fastening bars 8 into contact with the drone's bottom support, securing the support and parking the drone in the center of the placement plate 5. This completes the entire stopping process. Figure 1 As shown, the position of slider 11 needs to be adjusted during installation to ensure that the two sliders on the same second optical axis 12 move equal distances within the same time value, so as to avoid the two sliders 11 being out of sync and causing one of the fastening strips 8 to fail to contact the bottom bracket of the drone.

[0031] Furthermore, an extension rod 201 is installed vertically in the middle of the frame 2, and a sealing sphere 14 is installed at the top of the extension rod 201. A swing groove 15 is installed in the middle of the bottom of the floating trough 4. The swing groove 15 engages with the sealing sphere 14, causing the floating trough 4 to swing randomly. When the vehicle body is parked or tilted during movement, the floating trough 4 moves with the fluid inside the holding tank 3. When the floating trough 4 moves, it causes the swing groove 15 to rotate on the sealing sphere 14, thereby limiting the movement distance of the floating trough 4 and preventing the floating trough 4 from impacting the top when the vehicle body is subjected to strong vibrations, thus tearing and damaging the rubber edging 7.

[0032] Furthermore, each of the two parallel fastening strips 8 has a protrusion 801 fixedly installed in the middle. Each protrusion 801 has a lever 803 rotatably connected to both ends. A fixing cylinder 805 is fixedly installed at one end of each lever 803, and a second spring 804 is fixedly connected to the bottom of the fixing cylinder 805. A pressure ring 806 is connected to the bottom of the second spring 804. A miniature electric telescopic rod 802 is fixedly installed at the other end of each lever 803. The miniature electric telescopic rod 802 is fixedly connected to the protrusion 801, as described above: when the vehicle moves, if the vehicle is subjected to strong vibration, only one side of the bottom of the drone is locked. It is also unsafe. During long-term use, the belt is subjected to vibration, and the tension changes. The fastening strip 8 may shift with each vibration. Therefore, two safety measures are required. When the drone is docked on the placement plate 5, the movable rod of the mini electric telescopic rod 802 is in a retracted state, and the clamping ring 806 contacts the bottom bracket of the drone to prevent the drone from moving upward. When the drone needs to perform a task, the movable rod of the mini electric telescopic rod 802 is extended through the central control of the car. One end of the lever 803 is lifted upward, the clamping ring 806 separates from the bottom bracket of the drone, and then the movement operation of the fastening strip 8 is performed.

[0033] Compared to the swing groove 15, each side of the floating groove 4 is fixedly equipped with a bearing 13. A first spring 301 is connected between the inner ring of the bearing 13 and the holding groove 3. The bottom of the floating groove 4 is rounded to reduce the noise generated by the collision between the floating groove 4 and the holding groove 3. The elasticity of the first spring 301 needs to be very small to prevent the floating groove 4 from failing to perform self-leveling.

[0034] Furthermore, a cooling cylinder 16 is fixedly installed at each corner of the holding tank 3. Each cooling cylinder 16 has a pressure stabilizing hole 17 at its bottom. A ball rod 21 is rotatably connected to one side of the bottom of the pressure stabilizing hole 17. A hollow ball 18 is fixedly connected to the side of the ball rod 21 facing the holding tank 3. A through plate 22 is fixedly installed inside the cooling cylinder 16. One end of the ball rod 21 slides in contact with the through plate 22. A through port for liquid outflow is opened on the surface of the through plate 22. A transfer cylinder 23 is fixedly installed above the through port on the cooling cylinder 16. A spiral blade 24 is rotatably connected inside the transfer cylinder 23. At least eight cooling cylinders 16 are provided, and each cooling cylinder 16 has a through port at its top. The bottom of the spiral blade 24 is connected to a pulley via an air vent 20. One end of the pulley is connected to a third motor 19. When the vehicle body tilts, the fluid inside the holding tank 3 tends to the tilted side, causing the hollow ball 18 to be over-pressurized and tilt towards the other side of the cooling cylinder 16. As the hollow ball 18 performs this process, it drives the rod 21 to move, separating the top of the rod 21 from the through-hole of the through plate 22, drawing some fluid from the through-hole to the bottom of the transfer cylinder 23. The third motor 19 rotates intermittently, rotating within a certain time interval, driving the spiral blade 24 to rotate via the pulley, rotating the excess overflowing fluid, and discharging the fluid to the top of the transfer cylinder 23 for accumulation. Figure 8 As shown, the top of the transfer cylinder 23 and the cooling cylinder 16 are sealed. During the airflow process at the top of the cooling cylinder 16, the placement plate 5 is subjected to heat exchange through the vent 20. In addition, the top of the cooling cylinder 16 can be disassembled to remove the fluid. The fluid can be refilled into the holding tank 3 at intervals.

[0035] The initial position of the hollow sphere 18 is as follows Figure 9 As shown, when the vehicle body is horizontal, the hollow sphere 18 will be biased towards the cooling cylinder 16 side due to its own weight.

[0036] Both ends of the frame 2 are fixedly installed with locking shafts 6, and each locking shaft 6 is fixedly installed with a first optical shaft 602. A first motor 601 is fixedly installed in the middle of both sides of the frame 2. The output shaft of the first motor 601 is connected to a worm gear. A worm wheel 603 is fixedly connected to the first optical shaft 602. Removable hatches are installed at both ends of the locking shafts 6. An electronic control module is installed on the removable hatches to realize automated charging operation, which is convenient and fast. Moreover, during the charging operation, the dust accumulated on the dustproof screen can be back-blown and cleaned. After the air passes through the ventilation hole 20, it exchanges heat with the body to ensure that the heat generated during charging is dissipated, improve the heat dissipation effect, and reduce the occurrence of drone charging failures.

[0037] The surface of the placement plate 5 is frosted. The distance between the edge of the floating trough 4 and the inner wall of the holding trough 3 is 100mm. A guide block is provided in the middle of the placement plate 5 to help personnel find the stopping position.
