Description

Technical Field

[0001] The present invention relates to the technical field of drone take-off and landing platforms, and specifically to a retractable windowsill drone take-off and landing platform. Background Art

[0002] Drone (UAV) landing and takeoff platforms are critical infrastructure supporting drones' takeoff, landing, parking, and operational missions. Their performance directly impacts their operational capabilities and safety in complex environments. With the rapid development of the low-altitude economy, drones have been widely used in disaster monitoring, military operations, communications relay, and other fields, placing higher demands on the environmental adaptability, stability, and functional integration of landing and takeoff platforms. Modern UAV landing and takeoff platforms must be able to switch between land and water scenarios and accommodate the different sizes and landing and takeoff buffer requirements of different aircraft models, becoming indispensable physical nodes in the low-altitude intelligent Internet of Things (IIoT) system.

[0003] Existing drone take-off and landing platforms generally suffer from insufficient environmental adaptability, particularly a lack of modular solutions for amphibious switching between land and water. Traditional platforms often utilize a fixed structure and are unable to dynamically adjust to uneven ground or water conditions, resulting in tilting platforms and potential rollovers during drone take-off and landing. Independently designed floating platforms on the water are difficult to quickly convert to land mode, severely restricting cross-medium operational efficiency. This single-environment adaptability issue significantly limits drones in tasks requiring rapid scene switching, such as disaster relief and waterway inspections. Therefore, a retractable windowsill drone take-off and landing platform is proposed to address these issues. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a retractable windowsill drone take-off and landing platform to solve the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A retractable windowsill drone take-off and landing platform comprises a platform body, a support base provided at the bottom of the platform body, two airbags placed on top of the support base, two telescopic assemblies mounted on the bottom of the platform body, and the tops of the two airbags are fixed to the adjacent telescopic assemblies;

[0007] Wherein, temporary expansion pieces for temporarily increasing the landing area of ​​the platform body are rotatably connected to both sides of the platform body.

[0008] Furthermore, an escalator guardrail is installed on the side of the platform body, and a support net is slidably connected to the front of the platform body.

[0009] Furthermore, the telescopic assembly includes two connecting seats, the tops of the two connecting seats are each installed with a hinged seat, the tops of the two hinged seats are each rotatably connected to a support beam, a connecting block is installed at the bottom of the platform body, the ends of the two support beams away from the hinged seat are hinged to the connecting block, and the bottom of the connecting seat is fixed to the airbag.

[0010] Furthermore, the tops of the two connecting seats are hinged with hydraulic telescopic rods, and the tops of the two hydraulic telescopic rod output rods are hinged to the bottom of the platform body.

[0011] Furthermore, the temporary expansion piece includes a support rod, a handrail is installed on the top of the support rod, an auxiliary support block is installed on the top of the handrail, and the bottom of the support rod is hinged to the platform body.

[0012] Furthermore, the cross section of the auxiliary support block is a right-angled trapezoid.

[0013] Furthermore, a support plate is installed on the support rod, and multiple limit rods are installed on the support plate. The multiple limit rods are all slidably connected to the support plate. Two of the support rods are provided with buffer plates, and the buffer plates are equipped with multiple buffer springs that are sleeved on adjacent limit rods. The multiple buffer springs are connected to the support plate on one side away from the buffer plate.

[0014] Furthermore, the support base includes two bottom brackets, the tops of the two bottom brackets are in contact with the adjacent airbags, the interiors of the two bottom brackets are slidably connected with multiple sliding blocks, and each sliding block is slidably connected with a second one-way inflation valve, and air pumps are installed on the two bottom brackets, and the output ends of the two air pumps are connected to the multiple second one-way inflation valves in sequence.

[0015] Furthermore, a first one-way inflation valve is installed at the bottom of the airbag, and the first one-way inflation valve is inserted and connected with the airflow output end of the adjacent second one-way inflation valve.

[0016] Furthermore, a base body is installed at the bottom of each of the two bottom brackets, and a connecting pipe is fixed between the two base bodies.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This retractable windowsill drone landing platform utilizes an innovative modular design to achieve adaptive switching between land and water environments. The platform's main structure, incorporating telescopic components, airbags, and a support base, allows for height adjustment to accommodate uneven surfaces, both on and off the water, using hydraulic telescopic rods. The airbags also provide independent floating functionality. The ladder guardrail and support net design enhance operational convenience and emergency rescue capabilities. Temporary expansion elements, with their articulated structure and cushioning components, expand the landing area and reduce landing impact, fully accommodating the takeoff and landing needs of drones of varying sizes.

[0019] 2. The device's airbag inflation system and support base form an efficient closed-loop energy supply loop. The linkage between the one-way inflation valve and the air pump enables rapid airbag inflation, ensuring continuous operations on the water. Its structural design balances functionality and portability: temporary expansion units can be stored vertically to save space, the support base uses sliding blocks to enable rapid docking of the airbags, and the multi-directional articulated support system of the telescopic components ensures platform stability. This integrated design not only addresses the poor environmental adaptability of traditional take-off and landing platforms, but also extends the drone's service life through a buffering protection mechanism, significantly improving operational efficiency and safety in complex scenarios.

[0031] Reference Figure 1-6 A retractable windowsill drone take-off and landing platform includes a platform body 1, a support base 5 is provided at the bottom of the platform body 1, two air bags 4 are placed on the top of the support base 5, two telescopic components 2 are installed at the bottom of the platform body 1, and the tops of the two air bags 4 are fixed to the adjacent telescopic components 2;

[0032] Among them, temporary expansion parts 3 are rotatably connected on both sides of the platform body 1 to temporarily increase the landing area of ​​the platform body 1, escalator guardrails 11 are installed on the sides of the platform body 1, and a support net 12 is slidably connected to the front of the platform body 1.

[0033] Specifically, in actual operation of the device, the platform body 1 first serves as the main body, assisted by the telescopic component 2, the airbag 4 and the support base 5 as the bottom support. The telescopic component 2 can float up and down and telescope to adjust the height according to actual conditions, and the combination of the airbag 4 and the support base 5 can allow the platform body 1 to be supported on land, while the airbag 4 alone can keep the entire platform body 1 floating on the water. The side of the platform body 1 is installed with an escalator guardrail 11, which can facilitate the staff to enter the platform body 1, and the setting of the support net 12 can use the support net 12 to catch the unpowered drone in advance in some emergency situations.

[0034] As an optimization solution, Figure 1-6 As shown, the telescopic assembly 2 includes two connecting seats 22, the tops of the two connecting seats 22 are each installed with an articulated seat 23, the tops of the two articulated seats 23 are rotatably connected to support beams 24, and a connecting block 25 is installed at the bottom of the platform body 1. The ends of the two support beams 24 away from the articulated seat 23 are hinged to the connecting block 25, the bottom of the connecting seat 22 is fixed to the airbag 4, and the tops of the two connecting seats 22 are hinged with hydraulic telescopic rods 21, and the tops of the output rods of the two hydraulic telescopic rods 21 are hinged to the bottom of the platform body 1.

[0035] Specifically, in the telescopic assembly 2, the connecting seat 22 and the articulated seat 23 serve as the main support body, and then the connecting block 25 and the two support beams 24 provide lateral support. The auxiliary hydraulic telescopic rod 21 can realize the bottom support of the platform body 1 and be adjusted according to actual needs. When the ground or water surface is uneven, the hydraulic telescopic rod 21 on the corresponding side can be started to rise or fall to adjust and maintain the flatness of the platform body 1.

[0036] As an optimization solution, Figure 1-6 As shown, the temporary expansion member 3 includes a support rod 33, a handrail 37 is installed on the top of the support rod 33, an auxiliary support block 34 is installed on the top of the handrail 37, the bottom of the support rod 33 is hinged to the platform body 1, and the cross-section of the auxiliary support block 34 is a right-angled trapezoid. A support plate 35 is installed on the support rod 33, and a plurality of limit rods 32 are installed on the support plate 35. The plurality of limit rods 32 are all slidably connected to the support plate 35. The two support rods 33 are provided with a buffer plate 31, and the buffer plate 31 is equipped with a plurality of buffer springs 36 that are sleeved on adjacent limit rods 32. The plurality of buffer springs 36 are connected to the support plate 35 on the side away from the buffer plate 31.

[0037] Specifically, when the drone is large or needs a certain gliding distance, a temporary expansion piece 3 is needed. In the temporary expansion piece 3, the support rod 33 and the platform body 1 are hinged. However, while being hinged, the temporary expansion piece 3 can be fixed vertically to the top of the platform body 1 using screws when not in use, and then removed when needed. The maximum angle that the temporary expansion piece 3 can rotate is only to the level with the platform body 1. At this time, the platform body 1 and the temporary expansion pieces 3 on both sides form a larger plane together, and the drone can slide to above the buffer plate 31 after passing through the auxiliary support block 34. The auxiliary support block 34 is stably supported by the handrail 37 and the support rod 33, and the buffer plate 31 is stably supported by the limit rod 32 and the buffer spring 36 in cooperation with the support plate 35, and also has a certain buffering effect, reducing the damage to the drone body caused by landing.

[0038] As an optimization solution, Figure 1-5 As shown, the support base 5 includes two bottom brackets 56, the tops of the two bottom brackets 56 are both in contact with the adjacent airbags 4, the interiors of the two bottom brackets 56 are slidably connected with a plurality of sliding blocks 52, and each sliding block 52 is slidably connected with a second one-way inflation valve 53, and the two bottom brackets 56 are both installed with air pumps 54, and the output ends of the two air pumps 54 are connected with the plurality of second one-way inflation valves 53 in sequence, and the bottom of the airbag 4 is installed with a first one-way inflation valve 41, and the first one-way inflation valve 41 is inserted and connected with the airflow output end of the adjacent second one-way inflation valve 53, and the bottoms of the two bottom brackets 56 are both installed with a base body 51, and a connecting pipe 55 is fixed between the two base bodies 51.

[0039] Specifically, when it is necessary to be in water, the platform body 1 can be supported by the two air bags 4 and the telescopic assembly 2;

[0040] When on land, the two air bags 4 are placed on the support base 5. While the support base 5 itself plays a supporting role, the support base 5 cooperates with the base body 51, the connecting pipe 55 and the bottom bracket 56 to just hold the two air bags 4, and the sliding block 52 can be slid to cooperate with the first one-way inflation valve 41 on the air bag 4, so that the first one-way inflation valve 41 and the second one-way inflation valve 53 are inserted and connected. That is, when there is insufficient gas in the air bag 4, the air pump 54 can be started to let the gas flow from the connecting pipe 55 into the multiple second one-way inflation valves 53, and then supply it to the air bag 4 through the first one-way inflation valve 41, so that the air bag 4 is replenished with gas to cope with the next water operation.

[0041] Working Principle: In actual operation, the platform body 1 serves as the main body, supplemented by the telescopic component 2, airbag 4 and support base 5 as the bottom support. The telescopic component 2 can be adjusted up and down to adjust the height according to actual conditions. The combination of the airbag 4 and the support base 5 can support the platform body 1 on land, while the airbag 4 alone can keep the entire platform body 1 floating on the water.

[0042] The side of the platform body 1 is equipped with a ladder guardrail 11, which can facilitate the staff to enter the platform body 1, and the setting of the support net 12 can be used to catch the unpowered drone in advance in some emergency situations.

[0043] In the telescopic assembly 2, the connecting seat 22 and the articulated seat 23 serve as the main support, and then the connecting block 25 and the two support beams 24 provide lateral support. The auxiliary hydraulic telescopic rod 21 can achieve the bottom support of the platform body 1 and can be adjusted according to actual needs. When the ground or water surface is uneven, the hydraulic telescopic rod 21 on the corresponding side can be activated to raise or lower to adjust and maintain the flatness of the platform body 1.

[0044] When the drone is large or needs a certain gliding distance, a temporary expansion piece 3 is required. In the temporary expansion piece 3, the support rod 33 and the platform body 1 are hinged. However, when the temporary expansion piece 3 is not in use, the temporary expansion piece 3 can be fixed vertically to the top of the platform body 1 by screws while being hinged, and can be removed when needed. The maximum angle that the temporary expansion piece 3 can rotate is only to the level with the platform body 1. At this time, the platform body 1 and the temporary expansion pieces 3 on both sides form a larger plane, and the drone can slide above the buffer plate 31 after passing through the auxiliary support block 34. The auxiliary support block 34 is stably supported by the handrail 37 and the support rod 33, and the buffer plate 31 is stably supported by the limit rod 32 and the buffer spring 36 in cooperation with the support plate 35. It also has a certain buffering effect, reducing the damage to the drone body caused by landing.

[0045] When it is needed in water, the platform body 1 can be supported by the two air bags 4 and the telescopic assembly 2;

[0046] When on land, the two air bags 4 are placed on the support base 5. While the support base 5 itself plays a supporting role, the support base 5 cooperates with the base body 51, the connecting pipe 55 and the bottom bracket 56 to just hold the two air bags 4, and the sliding block 52 can be slid to cooperate with the first one-way inflation valve 41 on the air bag 4, so that the first one-way inflation valve 41 and the second one-way inflation valve 53 are inserted and connected. That is, when there is insufficient gas in the air bag 4, the air pump 54 can be started to let the gas flow from the connecting pipe 55 into the multiple second one-way inflation valves 53, and then supply it to the air bag 4 through the first one-way inflation valve 41, so that the air bag 4 is replenished with gas to cope with the next water operation.
