Description

Technical Field

[0001] The utility model relates to a multifunctional general airport, in particular to a multifunctional general airport for use by helicopters and eVTOL (electric vertical take-off and landing vehicle). Background Art

[0002] With the continuous pursuit of alleviating ground traffic congestion in megacities and improving emergency rescue response efficiency, the demand for air material transportation and air traffic travel has become more urgent. More and more cities will build new multi-functional general airports that can meet both helicopter takeoff and landing and eVTOL use.

[0003] In addition, most of the existing ground helipads or elevated helipads in cities do not have hangars, and aircraft are usually stored in the open air and exposed to wind, sun and rain, which shortens the life and maintenance cycle of aircraft. If hangars and corresponding maintenance and operation rooms are built outside a certain range of the take-off and landing area of ​​ground helipads or elevated helipads, the land scale requirements will be greatly increased, which is very difficult to achieve in many cities where land is expensive and land use is limited.

[0004] In addition, there are certain clearance requirements for helicopters and eVTOL takeoff and landing, but there are many buildings in the city and the clearance conditions are poor. Many places that want to build general airports on the ground that can meet the takeoff and landing requirements of helicopters and eVTOL cannot do so due to clearance issues. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a three-dimensional multifunctional general airport for use by helicopters and eVTOL (electric vertical take-off and landing vehicle) that can meet the take-off and landing needs of traditional helicopters and new eVTOLs, as well as the parking, trusteeship, repair, maintenance, passenger and cargo transportation of low-altitude aircraft and integrates hangars, terminals, cargo stations, refueling / charging stations, etc.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A multifunctional general airport for use by helicopters and eVTOLs comprises an airport building, a take-off and landing pad is arranged on the roof of the airport building, the interior of the airport building comprises a plurality of floors for parking helicopters or eVTOLs, and vertical lifting passages connecting each floor and the take-off and landing pad, the vertical lifting passages are connected to each floor via passage doors, the top of the vertical lifting passages is connected to the take-off and landing pad via a skylight, a lifting mechanism is installed in the vertical lifting passage, the lifting mechanism comprises a motor, a transmission mechanism, and a lifting platform, the motor drives the lifting platform to rise or fall along the height direction of the vertical lifting passage via the transmission mechanism.

[0008] Compared with the traditional flat airport, the utility model is a three-dimensional airport formed on the basis of an airport building with multiple floors. Each floor can park helicopters or eVTOLs and meet the functions of parking, trusteeship, repair, maintenance, passenger and cargo transportation of these low-altitude aircraft according to functional needs. Each floor in the airport building is connected to the vertical lifting channel through a channel door. A skylight and a guide rail used in conjunction with the skylight are installed on the top of the vertical lifting channel. The skylight is flush with the landing pad. A lifting platform serving as the landing and take-off area of ​​the airport side landing pad is installed in the vertical lifting channel. A lifting mechanism is installed under the lifting platform. When the skylight is opened along the guide rail, the lifting platform rises to be flush with the landing pad. When the lifting platform descends into the vertical lifting channel, the skylight is closed to prevent rainwater and the like from entering the airport building through the vertical lifting channel.

[0009] The utility model provides a multifunctional general airport for helicopters and eVTOLs, which has a vertical lifting passage connecting the ground and the building roof on the side of the airport building. The touchdown and liftoff area (TLOF) of the take-off and landing pad is the same size as the lifting platform. The lifting platform is driven by a lifting mechanism to achieve smooth lifting and lowering. A helicopter or eVTOL parked on the lifting platform can be lifted and lowered with it, and can enter and exit each floor of the airport building through the opened passage door through the traction equipment as needed. When a helicopter or eVTOL needs to take off or land, it first enters the lifting platform and rises to the top of the vertical lifting passage with the lifting platform.

[0010] In this way, on the one hand, the utility model integrates the functions of the airfield, hangar, terminal, cargo station, refueling / charging station, etc., which solves the problem of land shortage in urban areas, and at the same time solves the problem of aircraft being stored in the open air exposed to wind, sun and rain. On the other hand, the location height of the take-off and landing pad is increased, which effectively solves the clearance problem in urban areas and greatly increases the possibility of building general airports in urban areas.

[0011] Preferably, the roof of the airport building is provided with a plurality of landing pads, wherein the landing pad in the middle of the roof (middle landing pad) is an ordinary landing pad, which is connected to an elevator and stairs leading directly to the roof; the landing pads on both sides (side landing pads) are special landing pads, and the vertical lifting channel is arranged underneath them.

[0012] Preferably, at least two vertical lifting passages are arranged inside the airport building. When the passage door is opened, a helicopter or eVTOL located on the floor can enter and exit the lifting platform in the vertical lifting passage through the passage door with the help of a mobile traction device.

[0013] Preferably, the lifting mechanism also includes screw rods located at the four corners of the vertical lifting channel and lifting nuts threadedly connected to the screw rods, the lifting nuts are connected to the lifting platform, and the lifting platform and the lifting nuts move up and down with the rotation of the screw rods.

[0014] Preferably, the bottom surface of the vertical lifting passage is lower than the ground floor of the airport building, and the motor and the transmission structure are installed on the bottom surface of the vertical lifting passage. When the lifting platform descends to the bottom of the vertical lifting passage, the lifting platform is flush with the ground floor of the airport building.

[0015] Preferably, a guide rail is installed at the top of the vertical lifting channel, and the skylight is installed on the guide rail. The skylight slides along the guide rail to open or close the skylight.

[0016] Preferably, the transmission mechanism comprises a first transmission box connected to the motor, a second transmission box connected to the first transmission box, and a third transmission box connected to the second transmission box, and the third transmission box is connected to the screw rod. When the motor is started, the screw rod is driven to rotate through the transmission rod and the first to third transmission boxes in sequence, thereby driving the lifting nut and the lifting platform to rise and fall.

[0017] Preferably, a safety net and evacuation stairs are arranged around the landing pad.

[0018] Preferably, except for the stairs / elevator that leads directly to the roof and maintains a certain safety distance next to the landing pad, all components of all devices on the roof of the airport building are located below the landing pad or flush with the landing pad, and do not affect the clearance and safety of the take-off and landing of the helicopter.

[0019] Preferably, each parking position of the lifting platform in the vertical lifting channel corresponds to each floor of the airport building, and its upper surface is flush with the floor or roof of the airport when docked.

[0020] Preferably, the skylight is an electric waterproof skylight to facilitate the waterproofing of the vertical lifting channel and the automatic opening and closing of the skylight. The skylight and the lifting platform form a linkage relationship through electrical components. Before the lifting platform rises from the vertical lifting channel to its top, the linked electric waterproof skylight gradually opens. Before the lifting platform rises to the highest point, the electric waterproof skylight is fully opened; when the lifting platform descends from the top of the vertical lifting channel, the linked electric waterproof skylight gradually closes. When not in operation, the top surface of the skylight is flush with the landing pad surface around the top of the vertical lifting channel to prevent the skylight from affecting the docking and take-off operations of the aircraft.

[0021] Preferably, windows are arranged on the outer side of the vertical lifting passage to facilitate ventilation of the vertical lifting passage.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) The utility model integrates the functions of the airport flight area, hangar, terminal, cargo station, refueling / charging station, etc. and arranges them in a three-dimensional manner in an airport building. Compared with traditional similar general airports, the utility model occupies a very small area. The airport can be directly built in the urban area instead of being built far away from the urban area, which can effectively solve the problems of land shortage and high land costs in urban areas.

[0024] (2) The utility model general airport can not only meet the use of traditional helicopters, but also meet the use of eVTOL, which represents the future, and can also take into account the use of non-fixed-wing UAVs; it can not only meet the operation of a single low-altitude aircraft, but also meet the simultaneous operation of multiple low-altitude aircraft.

[0025] (3) The utility model general airport can effectively solve the problem of airspace clearance in urban areas by setting the take-off and landing area on the roof, greatly increasing the possibility of building a helicopter airport in the urban area.

[0026] (4) The utility model is provided with three landing pads, one fixed landing pad and two liftable landing pads, which can simultaneously meet the needs of various application scenarios such as stop and go, stop and go slowly, stop but not go, etc. At the same time, the landing pad is integrated with the hangar to prevent the aircraft from being exposed to wind, sun, rain and other problems.

In addition, the helicopter or eVTOL can stay in the vertical lifting channel 4, and the people or objects in the aircraft can be moved to a certain floor or ground through the channel door 13. When a helicopter or eVTOL needs to depart from the various floors inside the airport building and leave the general airport, the helicopter or eVTOL can reach any vertical lifting channel 4 on both sides through the electric door 13. Before the lifting platform 6 in the vertical lifting channel 4 rises to the top of the vertical lifting channel 4, the skylight 3 moves from closed to open along the guide rail 17. When the helicopter or eVTOL rises to the top of the vertical lifting channel 4, the helicopter or eVTOL can take off and fly to other places, or slide to the middle landing pad 1 to stay or wait for take-off.
