Description

Technical Field

[0001] This invention relates to the field of aircraft accessories technology, and in particular to a foldable support device and method for a high-rise take-off and landing platform for low-altitude aircraft. Background Technology

[0002] With the continuous development of low-altitude aircraft technology, such as drones, their applications in logistics, urban monitoring, and emergency rescue are becoming increasingly widespread. In urban environments filled with high-rise buildings, providing suitable takeoff and landing platforms for low-altitude aircraft has become a pressing issue.

[0003] However, existing technologies have revealed significant shortcomings in practical applications. On the one hand, takeoff and landing environments such as rooftops of high-rise buildings have unique flow field characteristics. Gusts and turbulence between buildings can easily cause unpredictable fluctuations in the attitude and descent speed of aircraft during landing, resulting in severe variable load impacts. Most existing support and buffer devices use springs or dampers with fixed stiffness, which cannot be adjusted according to real-time wind conditions or aircraft load: when the set stiffness is low, the buffer travel is easily exhausted when facing a heavy landing caused by gusts, resulting in a hard "bottoming out" collision; when the set stiffness is high, a normal landing will produce a violent rebound, causing the aircraft's attitude to become unstable. On the other hand, in order to resist high-altitude airflow disturbances, takeoff and landing platforms usually need to have a large support span to ensure anti-overturning capability, which often results in a huge overall size of the device. However, the space in the passages leading to the top floor of high-rise buildings (such as elevators, maintenance ladders, and narrow corridors) is extremely limited. Traditional wide-base support devices cannot pass through these narrow areas without sacrificing structural strength, making the deployment, retrieval, and relocation of the equipment extremely difficult. Summary of the Invention

[0004] The purpose of this invention is to solve existing problems by proposing a foldable support device and method for a high-rise building take-off and landing platform for low-altitude aircraft.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable support device for a high-rise building take-off and landing platform for low-altitude aircraft, comprising: A first support plate and a second support plate, wherein the first support plate and the second support plate are detachably connected to form a take-off and landing platform; Multiple connecting discs are fixedly installed at equal intervals on one side of the bottom of the first support plate and the second support plate; The docking components are installed on the bottom of the plurality of connecting discs located on the same side; Two support components, which are detachably snapped into the corresponding docking components, are used to provide cushioning support when a low-altitude aircraft lands on the take-off and landing platform.

[0006] In one possible design, the docking component includes: Multiple limiting tubes are fixedly installed at equal intervals on the bottom of the connecting plate; Multiple limiting rods are slidably connected to the corresponding limiting tubes; A retaining ring is fixedly connected to the bottom end of the plurality of limiting rods, and the retaining ring is used to engage with the supporting component.

[0007] In one possible design, the support component includes a first support tube and a second support tube symmetrically arranged on both sides of the first support tube, with the tops of the first support tube and the second support tube respectively engaging with the corresponding retaining rings; Both the first support tube and the second support tube are slidably connected with a top rod. The top end of the top rod extends above the retaining ring and engages with the connecting disc. The bottom of the top rod is provided with a pressing component. Both the first support tube and the second support tube have bent pipes fixed through their bottom sidewalls, and pressure regulating components are installed at the top of the bent pipes. When the lifting platform moves downward under load, the top rod is pressed down and drives the pressing component, so that the gas in the first support pipe or the second support pipe is forced into the pressure regulating component through the bend to produce a buffering effect.

[0008] In one possible design, the pressing assembly includes a piston plate fixedly mounted on the bottom end of the push rod, the piston plate being in a sealing sliding fit with the corresponding first support tube or second support tube; A compression spring is fixedly installed at the bottom of the piston plate, and the bottom end of the compression spring is fixedly connected to the bottom inner wall of the first support tube or the second support tube.

[0009] In one possible design, the voltage regulating component includes: A buffer tube is fixedly installed at the top end of the bend. The cap is sealed and snapped onto the top of the buffer tube; The load-bearing plate is in a sealing sliding fit with the inner wall of the buffer tube; Multiple connecting rods pass through an adjusting disc at equal intervals and slide in a sealed manner with the adjusting disc; the bottom ends of the multiple connecting rods are fixedly connected to the force-bearing plate. An adjusting component extends through and is rotatably connected to the cover, with the bottom of the adjusting component extending into the buffer tube and connected to the adjusting disc; In this process, the pressurized gas enters the buffer tube and pushes the force plate upward to compress the gas above the force plate.

[0010] In one possible design, the adjusting member includes a threaded cover that passes through and is rotatably connected to the cover, and a drive screw threadedly connected to the threaded cover, the bottom end of the drive screw extending into the buffer tube and fixedly connected to the top of the adjusting disc. Rotating the threaded cover can drive the adjusting disc to move longitudinally, thereby changing the pre-compression state of the gas between the force plate and the adjusting disc, and thus adjusting the buffer support force.

[0011] In one possible design, rotating rods are rotatably connected to the bottom of both sides of the first support tube, and a movable ring is slidably sleeved on the second support tube. The ends of the two rotating rods away from the first support tube are rotatably connected to the corresponding movable rings. A fixing rod is fixedly installed on one side of the top rod, and the fixing rod passes through the corresponding moving ring; By rotating the rotating rod, the second support tube can be moved closer to or away from the first support tube to achieve folding or unfolding.

[0012] In one possible design, a positioning screw is threaded through one side of the inner wall of the movable ring, and a slot is provided on the side wall of the fixed rod. Tightening the positioning screw will cause its end to press against the inner wall of the slot, thereby locking the position of the second support tube.

[0013] In one possible design, a plurality of threaded tubes are fixedly installed at equal intervals on the bottom of the first support plate, and a fixing plate is fixedly installed on one side of the bottom of the second support plate, wherein the fixing plate has insertion holes corresponding to the threaded tubes. The device further includes a fixing screw, which passes through the insertion hole and is threaded into the threaded tube. A pressure plate for pressing the fixing plate is fixedly sleeved on the fixing screw.

[0014] This invention proposes a method for using a foldable support device for a high-rise building take-off and landing platform of a low-altitude aircraft, comprising the following steps: S1. Install the take-off and landing platform: Splice the first support plate and the second support plate together, pass multiple fixing screws through the corresponding insertion holes on the bottom fixing plate of the second support plate, and then rotate the fixing screws to move them into the corresponding threaded tube at the bottom of the first support plate until the fixing plate is pressed by the pressure plate, thus completing the stable splicing of the first support plate and the second support plate to form a low-altitude aircraft take-off and landing platform. S2. Install the support components: Secure the top of the first support tube and the top of the two second support tubes of the support components to the corresponding retaining rings, so that the first support plate and the second support plate are connected to the corresponding support components respectively. S3. Adjusting the buffer support force of the support component: Rotate the threaded cover on the top cover of the buffer tube in the support component. Under the threaded transmission action of the threaded cover and the transmission screw, the adjustment plate is driven to move longitudinally, and the gas between the force plate and the adjustment plate is pre-compressed, thereby adjusting the buffer support force on the first support plate or the second support plate. S4. Adjusting the volume of the support components (when storing): If it is necessary to store the support components, rotate the rotating rods at the bottom of both sides of the first support tube upwards to bring the two second support tubes closer to the first support tube. When the rotating rods are rotated to a horizontal state, twist the positioning screw on the inner wall of the moving ring to extend one end into the slot on the side of the fixed rod and clamp it with the inner wall of the slot to position the second support tubes and the first support tubes. S5. Low-altitude aircraft landing buffer support: When the low-altitude aircraft lands on the landing platform, the first support plate and the second support plate support the low-altitude aircraft and move downward, driving the connecting plate to move downward. The connecting plate drives the push rod to move downward, and the push rod drives the piston plate to move downward. The piston plate transports the gas in the first support tube or the second support tube through the bend to the buffer tube, pushing the force plate to move upward and compressing the gas above the force plate. At the same time, the piston plate moves downward to press the compression spring. By utilizing the compressibility of gas and the elasticity of the compression spring, buffer support is achieved for the first support plate or the second support plate.

[0015] Beneficial effects

[0016] 1. This invention addresses the impact fluctuations caused by complex wind fields around tall buildings during landing. Operators can rotate the threaded cover to change the position of the adjustment disc, pre-adjusting the gas pressure within the buffer tube, thereby altering the overall buffer "hardness" of the support system. This design allows the device to both flexibly withstand minor landings and provide strong damping through a high-pressure air cushion under heavy impact conditions, effectively preventing bottoming-out damage or landing bounce, and significantly improving the landing stability of the aircraft in high-risk environments. 2. In this invention, when unfolded, the second support tubes on both sides expand outwards, forming a wide three-tube parallel support surface, significantly improving the anti-overturning moment upon landing; when retracted, the two support tubes are brought together tightly against the main tube through the cooperation of the rotating rod and the moving ring, instantly transforming into a slender columnar shape. This shape change, while retaining heavy-duty support capacity, greatly compresses the lateral volume, allowing it to easily pass through narrow maintenance passages or elevators in high-rise buildings, achieving a balance between high load-bearing capacity and spatial adaptability. 3. The modular splicing panel and quick-release snap-fit ​​support leg design adopted in this invention further decomposes the entire large lifting platform into several independent modules that are easy for a single person to carry. Combined with the folding characteristics of the support components, it perfectly adapts to the manual handling and rapid assembly requirements of high-rise building operation environments.

[0017] This invention addresses variable impact loads through an adjustable air pressure buffering mechanism and solves the problem of support stability under space constraints by utilizing a lateral folding structure, thus solving the problems of insufficient buffering and large size that are difficult to store in existing take-off and landing platforms.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment: Refer to Figure 1-9 A support device is provided, consisting of a first support plate 1 and a second support plate 2 assembled together. During assembly, the fixing plate 4 at the bottom of the second support plate 2 is aligned with the bottom of the first support plate 1, so that multiple insertion holes on the fixing plate 4 are aligned with multiple threaded tubes 3 at the bottom of the first support plate 1. Then, fixing screws 5 are passed through the corresponding insertion holes and screwed into the threaded tubes 3. As the fixing screws 5 are tightened, the pressure plate 6 on them presses tightly against the surface of the fixing plate 4, thereby securely connecting the first support plate 1 and the second support plate 2 into a single, integrated lifting platform surface.

[0022] like Figure 4 As shown, multiple connecting discs 7 are fixedly installed at equal intervals on one side of the bottom of the first support plate 1 and the second support plate 2. A common docking component is installed on the bottom of all connecting discs 7 located on the same side. This docking component includes multiple vertical limiting tubes 8, which are fixedly installed on the bottom of their respective connecting discs 7. A limiting rod 9 is slidably fitted inside each limiting tube 8, and the lower ends of all limiting rods 9 are fixedly connected to a horizontal retaining ring 10. To enhance the overall stability between the multiple retaining rings 10, an installation rod 11 is also fixedly connected between two adjacent retaining rings 10.

[0023] like Figure 6 As shown, the support function of this device is achieved through two independent support components, each of which is snapped into a corresponding docking component. The main body of the support component includes a first support tube 12 located in the middle and two second support tubes 121 symmetrically arranged on both sides of the first support tube 12. The top of the first support tube 12 and the top of the two second support tubes 121 are respectively snapped into corresponding retaining rings 10 to achieve initial positioning of the upper part.

[0024] like Figure 7-8 As shown, a push rod 13 is slidably disposed inside each of the first support tube 12 and the second support tube 121. The top end of the push rod 13 extends upward, passes through the retaining ring 10, and engages with the connecting disc 7 above. A piston plate 14 is fixedly mounted at the bottom end of the push rod 13, and the piston plate 14 maintains a tight sliding seal with the inner wall of the support tube. A compression spring 16 is disposed below the piston plate 14, and the bottom end of the compression spring 16 is fixed to the bottom inner wall of the support tube. Inside the support tube, a first support ring 15 is also fixed below the piston plate 14 to provide initial support or limit the downward displacement of the piston plate 14.

[0025] like Figure 9 As shown, a bent pipe 17 is fixedly installed through the inner wall of the bottom side of each of the first support pipes 12 and the second support pipe 121. A pressure regulating assembly is connected to the top of the bent pipe 17. The pressure regulating assembly includes a vertical buffer pipe 18, the top of which is sealed by a cap 19. Inside the buffer pipe 18 is a sliding force plate 20, which is tightly slidably sealed against the inner wall of the buffer pipe 18. Multiple connecting rods 21 are fixed at equal intervals above the force plate 20, passing upwards through an adjusting disc 22 and maintaining a sliding seal with the adjusting disc 22. A transmission screw 24 is fixed at the top center of the adjusting disc 22, passing upwards through the cap 19 and threadedly connected to a threaded cover 23, which is rotatably connected to the cap 19. By rotating the threaded cover 23, the transmission screw 24 can be driven to move the adjusting disc 22 up and down within the buffer pipe 18. Inside the buffer tube 18, a second support ring 25 is fixed below the force plate 20 to support the initial position of the force plate 20.

[0026] This application can be used in the field of aircraft parts technology, or in other fields applicable to this application.

[0027] In another embodiment: Reference Figure 6 Based on the above embodiments, an improvement is made to a foldable support device for a high-rise building take-off and landing platform for low-altitude aircraft, which is applied to the field of aircraft accessory technology. The structure of this embodiment is basically the same as the previous embodiments, except that: in order to enable the support components to be folded and stored, rotating rods 26 are rotatably connected to the bottom of both sides of the first support tube 12. A movable ring 27 is slidably sleeved on each second support tube 121. The ends of the two rotating rods 26 away from the first support tube 12 are rotatably connected to the corresponding movable rings 27. A fixed rod 28 extending from the side of the top rod 13 passes horizontally through the corresponding movable ring 27. A positioning screw 30 is threadedly connected to the inner wall of one side of the movable ring 27. A slot 29 is opened on the side of the fixed rod 28. Rotating the positioning screw 30 can make its end abut against the inner wall of the slot 29, thereby achieving fixation.

[0028] When a low-altitude aircraft lands on a platform consisting of a first support plate 1 and a second support plate 2, the increased weight of the platform causes it to move downwards. This downward movement is transmitted to the push rod 13 via the connecting plate 7, causing the push rod 13 to slide downwards within its support tube. The push rod 13 drives the piston plate 14 downwards, compressing the compression spring 16 below it and simultaneously forcing the gas in the lower cavity of the support tube into the buffer tube 18 through the bend 17. The gas entering the buffer tube 18 pushes the force plate 20 upwards against the pressure of the gas above it. Throughout the process, the storage and release of the elastic potential energy of the compression spring 16, and the compression and expansion of the gas in the buffer tube 18, work together to buffer the downward pressure. This device can actively intervene in the buffering characteristics to address the impact energy under different wind conditions or loads. If a large landing impact is anticipated (such as in windy weather or with a heavy-load aircraft), the threaded cover 23 is pre-tightened, forcing the adjusting plate 22 downwards and compressing the gas between it and the force plate 20, thus establishing a high-pressure air cushion. When the piston plate 14 descends and forces gas in, the load-bearing plate 20 faces greater upward resistance, thus exhibiting stronger support stiffness and rapidly dissipating the enormous impact energy. Conversely, if the aircraft is lighter or the landing is smooth, the threaded cover 23 is loosened to reduce the air cushion pressure and provide flexible cushioning. This variable stiffness mechanism ensures that the platform can match the optimal cushioning curve under different operating conditions.

[0029] When moving items through narrow high-rise maintenance passages, the support components can be folded to reduce volume. To operate, first loosen the positioning screws 30 on each moving ring 27, disengaging their ends from the slots 29 on the fixing rod 28. Then, rotate the rotating rod 26 upwards, causing the moving ring 27 and its associated second support tube 121 to move closer to the first support tube 12. Once the two second support tubes 121 are close to the first support tube 12, rotate the rotating rod 26 to a roughly horizontal position. Then, tighten the positioning screws 30 again, engaging their ends into the slots 29 on the fixing rod 28 to lock the folded state. The unfolding process is the reverse: first loosen the positioning screws 30, then move the second support tube 121 outwards to the working position and fix it.

[0030] This device effectively cushions the landing of low-altitude aircraft through a modular platform, snap-fit ​​docking components, and a support structure incorporating a composite spring and pneumatic buffer. Its foldable support components facilitate storage and transportation when not in use, saving space. The connections between the components are clearly defined, the operating procedures are straightforward, and it demonstrates excellent feasibility and operability.

[0031] This invention proposes a method for using a foldable support device for high-rise building take-off and landing platforms of low-altitude aircraft, comprising the following steps: S1. Install the take-off and landing platform: splice the first support plate 1 and the second support plate 2, pass multiple fixing screws 5 through the corresponding insertion holes on the bottom fixing plate 4 of the second support plate 2, and then rotate the fixing screws 5 to move them into the corresponding threaded tube 3 at the bottom of the first support plate 1 until the pressure plate 6 is used to press the fixing plate 4, thus completing the stable splicing of the first support plate 1 and the second support plate 2 to form a low-altitude aircraft take-off and landing platform. S2. Install the support components: Secure the top of the first support tube 12 and the top of the two second support tubes 121 of the support components to the corresponding retaining rings 10, so that the first support plate 1 and the second support plate 2 are connected to the corresponding support components respectively. S3. Adjusting the buffer support force of the support component: Rotate the threaded cover 23 on the top cover 19 of the buffer tube 18 in the support component. Under the threaded transmission action of the threaded cover 23 and the transmission screw 24, the adjusting plate 22 is driven to move longitudinally, and the gas between the force plate 20 and the adjusting plate 22 is pre-compressed, thereby adjusting the buffer support force on the first support plate 1 or the second support plate 2. S4. Adjusting the volume of the support components (when storing): If it is necessary to store the support components, rotate the rotating rods 26 at the bottom of both sides of the first support tube 12 upwards, so that the two second support tubes 121 move closer to the first support tube 12. When the rotating rods 26 rotate to a horizontal state, twist the positioning screw 30 on one side of the inner wall of the moving ring 27, so that one end of it extends into the slot 29 on one side of the fixed rod 28 and is clamped to the inner wall on one side of the slot 29, thereby positioning the second support tubes 121 and the first support tube 12. S5. Low-altitude aircraft landing buffer support: When the low-altitude aircraft lands on the landing platform, the first support plate 1 and the second support plate 2 support the low-altitude aircraft and move downward, driving the connecting plate 7 to move downward. The connecting plate 7 drives the top rod 13 to move downward, and the top rod 13 drives the piston plate 14 to move downward. The piston plate 14 transports the gas in the first support tube 12 or the second support tube 121 through the bend pipe 17 to the buffer tube 18, pushing the force plate 20 to move upward and compressing the gas above the force plate 20. At the same time, the piston plate 14 moves downward to press the compression spring 16. By utilizing the compressibility of gas and the elasticity of the compression spring 16, buffer support is achieved for the first support plate 1 or the second support plate 2.

[0032] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method of using a foldable support device for a high-rise take-off and landing platform of a low-altitude aircraft according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Install the take-off and landing platform: splice the first support plate (1) and the second support plate (2), pass multiple fixing screws (5) through the corresponding insertion holes on the bottom fixing plate (4) of the second support plate (2), and then rotate the fixing screws (5) to move them into the corresponding threaded tube (3) at the bottom of the first support plate (1) until the fixing plate (4) is pressed by the pressure plate (6) to complete the stable splicing of the first support plate (1) and the second support plate (2) to form a low-altitude aircraft take-off and landing platform; S2. Install the support components: Secure the top of the first support tube (12) and the top of the two second support tubes (121) of the support components to the corresponding retaining rings (10) respectively, so that the first support plate (1) and the second support plate (2) are connected to the corresponding support components respectively. S3. Adjust the buffer support force of the support component: Rotate the threaded cover (23) on the top cover (19) of the buffer tube (18) in the support component. Under the threaded transmission action of the threaded cover (23) and the transmission screw (24), the adjustment plate (22) is driven to move longitudinally, and the gas between the force plate (20) and the adjustment plate (22) is pre-compressed, thereby adjusting the buffer support force on the first support plate (1) or the second support plate (2). S4. Adjusting the volume of the support components (when storing): If it is necessary to store the support components, rotate the rotating rods (26) at the bottom of both sides of the first support tube (12) upwards, so that the two second support tubes (121) move closer to the first support tube (12). When the rotating rods (26) rotate to the horizontal state, twist the positioning screw (30) on the inner wall of the moving ring (27) so that one end extends into the slot (29) on the side of the fixed rod (28) and clamps it with the inner wall of the slot (29) to position the second support tubes (121) and the first support tube (12). S5. Low-altitude aircraft landing buffer support: When the low-altitude aircraft lands on the landing platform, the first support plate (1) and the second support plate (2) support the low-altitude aircraft and move downward, driving the connecting plate (7) to move downward. The connecting plate (7) drives the top rod (13) to move downward. The top rod (13) drives the piston plate (14) to move downward. The piston plate (14) transports the gas in the first support tube (12) or the second support tube (121) through the bend pipe (17) to the buffer tube (18), pushing the force plate (20) to move upward and compressing the gas above the force plate (20). At the same time, the piston plate (14) moves downward to press the compression spring (16). By utilizing the compressibility of gas and the elasticity of the compression spring (16), buffer support is achieved for the first support plate (1) or the second support plate (2).
