Description

Technical Field

[0001] This utility model relates to a take-off and landing building platform for vertical take-off and landing aircraft, belonging to the field of building platform technology. Background Technology

[0002] As ground traffic congestion in major cities worsens, the demand for air cargo transport and air travel becomes increasingly urgent, thus giving rise to the low-altitude economy. The low-altitude economy refers to low-altitude flight activities within low-altitude airspace, centered on civilian manned and unmanned aircraft, encompassing various scenarios such as passenger transport, cargo transport, and other operations.

[0003] With the rapid development of the low-altitude economy, short-haul helicopter travel has become increasingly common, and drone delivery services, such as express delivery and medical supply transport, have become more convenient and efficient. For this new mode of low-altitude transportation, the construction of facilities capable of accommodating small manned helicopters and drones with vertical take-off and landing (VTOL) capabilities is an indispensable infrastructure guarantee for meeting the needs of low-altitude flight.

[0004] Currently, the infrastructure for the low-altitude economy includes ground helipads and rooftop parking platforms. Helicopters or drones can be parked on ground helipads or rooftop platforms. On ground helipads, each aircraft is laid flat, occupying a large space and requiring a large area of ​​land, which is especially difficult to achieve in many cities with limited land. Existing cities have many tall buildings, which can be used for parking on rooftop platforms. However, these platforms are usually open-air, and aircraft stored in the open are exposed to wind and sun, which can affect their lifespan over time. In addition, aircraft maintenance also needs to be carried out in the open, making maintenance inconvenient.

[0005] In addition, as a lifting platform specifically designed for vertical take-off and landing aircraft, the aircraft usually takes off and lands on the top floor. When not in flight, the aircraft needs to be moved to the next floor for storage or maintenance via the lifting mechanism. In this case, the lifting well on the top floor needs to be covered with a rainproof cover. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a take-off and landing building platform for vertical take-off and landing aircraft.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A take-off and landing building platform for a vertical take-off and landing aircraft includes a building body, a take-off and landing platform is provided on the top of the building body, a fixed parking position and an elevator parking position are provided on the take-off and landing platform, an elevator shaft is provided on the take-off and landing platform, an elevator platform is provided at the elevator parking position, and the elevator parking position is located at the elevator shaft. It also includes a waterproof shielding device installed at the elevator shaft opening. The waterproof shielding device includes a telescopic roller shutter, guide rails installed on the left and right sides of the telescopic roller shutter, and a roller shutter box for storing the telescopic roller shutter. The waterproof shielding device can close the elevator shaft opening after the elevator platform enters the interior of the building. The end of the guide rail closest to the roller shutter box is the front end of the guide rail, and the end of the guide rail away from the roller shutter box is the rear end of the guide rail. The guide rail is inclined, and the front end of the guide rail is 50-200mm higher than the rear end of the guide rail.

[0008] The beneficial effects of this utility model are as follows: This building platform is equipped not only with fixed parking positions but also with lifting parking positions. Each lifting parking position has a lifting platform, allowing the VTOL aircraft to enter the building's interior for parking and maintenance. This effectively solves the problem of large space occupation caused by aircraft laid flat on top of the building platform in existing technologies, making full use of the platform's internal space. A waterproof shielding device is installed at the lifting shaft opening. The retractable roller shutter can be opened to cover the lifting shaft opening and closed promptly after the lifting platform enters the building, effectively preventing rainwater, dust, and other external factors from entering the building's interior, protecting the VTOL aircraft and the building itself. Simultaneously, the inclined design of the guide rail, while ensuring the normal opening and closing of the retractable roller shutter, also has a drainage function. Rainwater on the retractable roller shutter flows to the rear end of the guide rail, preventing rainwater accumulation on the retractable roller shutter and affecting its smooth operation. This fulfills the requirement that the waterproof shielding device effectively covers the lifting shaft opening, thereby protecting the aircraft, the retractable roller shutter, and the building's facilities from the effects of severe weather.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the front end of the guide rail is 80-150mm higher than the rear end of the guide rail.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the front end of the guide rail being higher than the rear end allows rainwater on the retractable roller shutter to flow more smoothly to the rear end of the guide rail, ensuring the drainage performance of the waterproof shielding device. This prevents rainwater accumulation on the retractable roller shutter, reducing the risk of malfunction or damage due to water accumulation, and protecting the vertical takeoff and landing aircraft and internal building facilities from rainwater damage.

[0012] Furthermore, the tilt angle of the guide rail is 1.5-5 degrees.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the guide rail tilted at 1.5-5 degrees can guide the rainwater on the retractable roller shutter to flow to the rear end of the guide rail, ensuring its drainage function, while the angle is too large and will not affect the normal opening and closing of the retractable roller shutter.

[0014] Furthermore, the take-off and landing platform is provided with a water guide channel perpendicular to the guide rail. The water guide channel is located at the rear end of the guide rail and can collect water on the telescopic roller shutter and guide it to the building's drainage pipe for discharge from the building.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the water guide channel located at the rear end of the guide rail can collect rainwater flowing down from the retractable roller shutter. At the same time, the outlet of the water guide channel is connected to the building's drainage pipes, which can ensure that the collected rainwater can be smoothly and timely discharged into the building's drainage system, avoiding the accumulation of rainwater on the take-off and landing platform and affecting the aircraft's start-up and shutdown.

[0016] Furthermore, the guide rail has a C-shaped cross-section.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the C-shaped track provides guidance, limit and support for the opening and closing of the telescopic roller blind, which can better support and guide the operation of the telescopic roller blind, and ensure the stability and smoothness of the telescopic roller blind.

[0018] Furthermore, the telescopic roller blind includes multiple parallel curtain panels, and each curtain panel has rollers at both ends that can move within the guide rail.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the rollers at both ends of the curtain panel can move within the guide rail, and the rollers and guide rails have rolling friction, which makes the retractable roller blind open and close more smoothly, reduces friction and jamming, and improves the reliability of the retractable roller blind.

[0020] Furthermore, the telescopic roller blind includes multiple parallel curtain panels, each with a slider at both ends that can move within the guide rail, and ball bearings between the bearing surface of the guide rail and the slider.

[0021] The beneficial effect of adopting the above-mentioned further solution is that sliders can also be set at both ends of the curtain panel. The sliders move in the guide rail. In order to make the sliders and guide rails cooperate more smoothly, ball bearings can be set between the sliders and the bearing surfaces of the guide rails to convert sliding friction into rolling friction, reduce the frictional resistance of the retractable roller blind during opening and closing, make the opening and closing of the retractable roller blind more effortless, and at the same time reduce wear caused by friction, and extend the service life of the retractable roller blind and the guide rail.

[0022] Furthermore, the ball bearings are embedded in the slider or on the bearing surface of the guide rail.

[0023] The advantage of adopting the above-mentioned further solution is that the ball bearings can be embedded in the slider, or they can be embedded in the bearing surface of the guide rail, ensuring the smooth opening and closing of the telescopic roller shutter.

[0024] Furthermore, the roller shutter box is suspended from the bottom of the landing platform.

[0025] The advantages of adopting the above-mentioned further solution are that the roller shutter box can store the retractable roller shutter when it is not necessary to cover the lift shaft. The roller shutter box is suspended on the take-off and landing platform, which can make full use of the space under the take-off and landing platform. The roller shutter box is not set on the top of the take-off and landing platform because no facilities higher than 25cm above the surface of the take-off and landing platform are allowed within at least 3 meters around the aircraft take-off and landing. For safety reasons, the roller shutter box is placed in the building. The roller shutter box is suspended on the take-off and landing platform, which can meet the need for the retractable roller shutter to open and cover the lift shaft. In addition, it does not occupy the space on the take-off and landing platform, and the overall aesthetics and practicality of the building platform are enhanced. It also avoids the problems of wind and sun exposure caused by open-air storage.

[0026] Furthermore, the lifting platform can enter the building under the action of the lifting mechanism, and is used to carry the vertical take-off and landing aircraft for parking or maintenance within the building.

[0027] The advantages of adopting the above-mentioned further solutions are that the relatively enclosed space inside the building can provide a safe parking and maintenance environment for vertical take-off and landing aircraft; the aircraft can enter the building through the lift platform and be protected from the effects of severe weather such as wind, rain and sun exposure, and can be carried out in a detailed manner for maintenance and repair work inside the building.

[0028] Furthermore, the lifting mechanism includes a lifting frame, a lifting rail for guiding the lifting frame, and a lifting drive mechanism for driving the lifting frame to move up and down. The lifting platform is disposed on the lifting frame. A positioning mechanism is also provided between the lifting frame and the lifting rail. The positioning mechanism includes a positioning pin, a positioning hole, and a positioning drive cylinder for driving the positioning pin to extend and retract. The positioning pin is disposed on the lifting frame or the lifting rail, and the positioning hole is disposed on the lifting rail or the lifting frame.

[0029] The advantages of adopting the above-mentioned further solution are that there can be multiple positioning holes, which are respectively set at corresponding positions on the lifting track, such as the top position of the lifting platform, the corresponding position on the corresponding floor inside the building, etc. Through the cooperation of the lifting frame, the lifting track and the lifting drive mechanism, the lifting platform can move stably up and down, meeting the needs of the vertical take-off and landing aircraft at different heights inside the building, and can be parked or maintained on the corresponding floor inside the building; the positioning mechanism can lock and position the lifting platform after it is raised to the position, avoiding instability such as shaking of the lifting platform, and ensuring the stability and safety of the lifting platform.

[0031] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0032] like Figures 1-6 As shown, a take-off and landing building platform for a vertical take-off and landing aircraft includes a building body 4, a take-off and landing platform 1 on the top of the building body 4, a fixed parking position 2 and an elevator parking position 3 on the take-off and landing platform 1, an elevator shaft on the take-off and landing platform 1, an elevator platform 7 at the elevator parking position 3, and the elevator parking position 3 is located at the elevator shaft. It also includes a waterproof shielding device 6 installed at the elevator shaft opening. The waterproof shielding device 6 includes a telescopic roller shutter 601, guide rails 602 installed on the left and right sides of the telescopic roller shutter 601, and a roller shutter box 603 for storing the telescopic roller shutter 601. The waterproof shielding device 6 can close the elevator shaft opening after the elevator platform 7 enters the interior of the building body 4. The end of the guide rail 602 closest to the roller shutter box 603 is the front end of the guide rail 602, and the end of the guide rail 602 furthest from the roller shutter box 603 is the rear end of the guide rail 602. The guide rail 602 is inclined, and the front end of the guide rail 602 is 50-200mm higher than the rear end of the guide rail 602.

[0033] The front end of the guide rail 602 is 80-150mm higher than the rear end of the guide rail 602. This higher front end allows rainwater on the retractable roller shutter 601 to flow more smoothly to the rear end of the guide rail 602, ensuring the drainage performance of the waterproof shielding device 6. This prevents rainwater accumulation on the retractable roller shutter 601, reducing the risk of malfunction or damage due to water accumulation, and protecting the vertical takeoff and landing aircraft and the internal facilities of the building 4 from rainwater damage.

[0034] The front end of the guide rail 602 is 65mm, 70mm, 80mm, 85mm, 93mm, 100mm, 110mm, 115mm, 124mm higher than the rear end of the guide rail 602.

[0035] The guide rail 602 has an inclination angle of 1.5-5 degrees. The inclination of the guide rail 602 at 1.5-5 degrees can guide the rainwater on the retractable roller shutter 601 to flow to the rear end of the guide rail 602 to ensure its drainage function, while also preventing the normal opening and closing of the retractable roller shutter 601 from being affected by an excessively large angle.

[0036] The tilt angle of the guide rail 602 can be 1.5 degrees, 2 degrees, 2.3 degrees, 3 degrees, 3.5 degrees, etc.

[0037] The take-off and landing platform 1 is equipped with a water guide trough 5 perpendicular to the guide rail 602. The water guide trough 5 is located at the rear end of the guide rail 602. The water guide trough 5 can collect water on the telescopic shutter 601 and guide it to the drainage pipe of the building 4 for discharge. The water guide trough 5, located at the rear end of the guide rail 602, can collect rainwater flowing down from the telescopic shutter 601. At the same time, the outlet of the water guide trough 5 is connected to the drainage pipe of the building 4, which can ensure that the collected rainwater can be smoothly and timely discharged into the drainage system of the building 4, avoiding the accumulation of rainwater on the take-off and landing platform 1 and affecting the take-off and landing of the aircraft.

[0038] The middle of the water guide channel 5 is higher than the middle position of its left and right outlets. This facilitates the smooth flow of rainwater collected by the water guide channel 5 to the drainage pipes on both sides of the building 4 for timely drainage.

[0039] The cross-sectional shape of the water guide channel 5 is a triangular structure, a trapezoidal structure, or a rectangular structure.

[0040] The guide rail 602 has a C-shaped cross-section. The C-shaped rail provides guidance, limitation and support for the opening and closing of the telescopic roller blind 601, which can better support and guide the operation of the telescopic roller blind 601, and ensure the stability and smoothness of the telescopic roller blind 601.

[0041] like Figure 4 The diagram shows the retractable roller blind 601 in operation with the guide rail 602 via rollers 604. The retractable roller blind 601 includes multiple parallel curtain panels, each with rollers 604 at both ends that can travel within the guide rail 602. The rollers 604 at both ends of the curtain panels move within the guide rail 602, and the rolling friction between the rollers 604 and the guide rail 602 makes the opening and closing of the retractable roller blind 601 smoother, reducing friction and jamming, and improving the reliability of the retractable roller blind 601.

[0042] The roller shutter box 603 is suspended from the bottom of the landing platform 1. When it is not necessary to cover the lift shaft, the roller shutter box 603 can store the retractable roller shutter 601. Suspending the roller shutter box 603 on the landing platform 1 makes full use of the space below the platform. The roller shutter box 603 is not located on the top of the landing platform 1 because no facilities exceeding 25cm above the surface of the landing platform 1 are allowed within at least 3 meters of the aircraft's takeoff and landing area. For safety reasons, the roller shutter box 603 is placed inside the building 4. Suspending the roller shutter box 603 on the landing platform 1 allows the retractable roller shutter 601 to be opened to cover the lift shaft. Furthermore, it does not occupy space on the landing platform 1, enhancing the overall aesthetics and practicality of the building platform and avoiding the problems of wind and sun exposure caused by open-air storage.

[0043] The lifting platform 7, under the action of the lifting mechanism, can enter the building 4 to carry the vertical take-off and landing aircraft for parking or maintenance within the building 4. The relatively enclosed space inside the building 4 provides a safe parking and maintenance environment for the vertical take-off and landing aircraft; the aircraft, entering the building 4 via the lifting platform 7, can be protected from the effects of harsh external weather such as wind, rain, and sun exposure, and can undergo detailed maintenance and repair work inside the building 4.

[0044] The lifting mechanism includes a lifting frame 8, a lifting rail 9 for guiding the lifting frame 8, and a lifting drive mechanism for driving the lifting frame 8 up and down. The lifting platform 7 is mounted on the lifting frame 8. A positioning mechanism is also provided between the lifting frame 8 and the lifting rail 9. The positioning mechanism includes a positioning pin 14, a positioning hole, and a positioning drive cylinder 15 for driving the positioning pin to extend or retract. The positioning pin 14 is mounted on the lifting frame 8 or the lifting rail 9, and the positioning hole is mounted on the lifting rail 9 or the lifting frame 8. Figure 6 As shown, the positioning pin 14 of the positioning mechanism is set on the lifting frame 8 through the positioning drive cylinder 15. There can be multiple positioning holes, which are respectively set at the corresponding stop positions of the lifting platform on the lifting rail 9, such as the top position of the lifting platform, the position of the corresponding floor in the building, etc. Through the cooperation of the lifting frame, the lifting rail and the lifting drive mechanism, the lifting platform can move up and down stably, which meets the needs of the vertical take-off and landing aircraft at different height positions in the building. It can be parked or maintained on the corresponding floor in the building. The positioning mechanism can lock the lifting platform after it is raised to the position to avoid the lifting platform from shaking or other unstable situations, and ensure the stability and safety of the lifting platform.

[0045] The lifting mechanism includes a lifting frame 8, a pair of lifting rails 9 for guiding the lifting frame 8, and a lifting drive mechanism for driving the lifting frame 8 to move up and down. The lifting frame 8 and the lifting rails 9 are in sliding or rolling cooperation.

[0046] The lifting drive mechanism includes a hydraulic drive cylinder 10, a transmission sprocket 12, and a transmission chain 13. The driven sprocket is rotatably mounted on the balance beam 11. The piston rod of the hydraulic drive cylinder 10 is connected to the balance beam 11. The balance beam 11 can move up and down along the lifting track 9. One end of the transmission chain 13 is fixed, and the other end passes around the transmission sprocket 12 and is connected to the lifting frame 8.

[0047] A positioning pin 14 can also be set on the lifting frame 8. There are multiple positioning holes along the height direction on the lifting rail 9 for the positioning pin 14 to be inserted. The positioning pin 14 is connected to the piston rod of the positioning drive cylinder 15. After the lifting platform 7 is lifted into place, the positioning pin 14 extends out under the action of the positioning drive cylinder 15 and can be inserted into the positioning hole at the corresponding position, thereby ensuring the stability and reliability of the lifting platform 7 after it is in place.

[0048] like Figure 5As shown, another configuration of the retractable roller blind 601 and guide rail 602 is illustrated. The retractable roller blind 601 includes multiple parallel curtain panels. Each curtain panel has a slider 605 at both ends, capable of moving within the guide rail 602. A ball bearing 606 is positioned between the bearing surface of the guide rail 602 and the slider 605. Alternatively, sliders 605 can also be positioned at both ends of the curtain panels, moving within the guide rail 602. To ensure smoother operation between the slider 605 and the guide rail 602, a ball bearing 606 can be positioned between the bearing surfaces of the slider 605 and the guide rail 602, converting sliding friction into rolling friction. This reduces frictional resistance during opening and closing of the retractable roller blind 601, making opening and closing the blind easier and reducing wear caused by friction, thus extending the service life of both the retractable roller blind 601 and the guide rail 602.

[0049] The ball bearing 606 is embedded in the slider 605 or on the bearing surface of the guide rail 602. The ball bearing 606 can be embedded in the slider 605 or on the bearing surface of the guide rail 602 to ensure the smooth opening and closing of the telescopic roller shutter 601.

[0050] This utility model's building platform is equipped with a fixed parking position 2 and an elevator parking position 3. An elevator platform 7 is located at the elevator parking position 3. The vertical take-off and landing (VTOL) aircraft can park at the fixed parking position on the building platform, or it can enter the building body 4 via the elevator platform 7 for parking, maintenance, etc., within the building body 4. This solves the problem of existing technologies where aircraft are laid flat on top of the building platform, occupying a large amount of space, and makes full use of the internal space of the building platform. A waterproof shielding device 6 and a retractable roller shutter 601 are installed at the elevator shaft opening. These devices can be opened to cover the elevator shaft opening and closed promptly after the elevator platform 7 enters the building body 4, effectively preventing rainwater, dust, and other external factors from entering the building body 4, thus protecting the VTOL aircraft and the building body 4. Meanwhile, the inclined setting of the guide rail 602, while ensuring the normal opening and closing of the telescopic roller shutter 601, also has a drainage function. Rainwater on the telescopic roller shutter 601 flows to the rear end of the guide rail 602 and can be collected and flow into the water guide channel 5. The rainwater entering the water guide channel 5 will flow towards the outlets on the left and right sides of the water guide channel 5, and then flow into the drainage pipe of the building 4. The rainwater is drained smoothly through the drainage pipe, preventing rainwater from accumulating on the telescopic roller shutter 601 and affecting its smooth operation. This meets the requirement that the waterproof shielding device 6 can shield the lifting well opening, thereby protecting the aircraft, the telescopic roller shutter 601, and the equipment inside the building 4 from the effects of severe weather.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
