Description

Technical Field

[0001] The present invention relates to the field of aircraft, and in particular to an intelligent retractable platform suitable for eVTOL (electric Vertical Take-Off and Landing, eVTOL for short) with a small helium airbag. Background Art

[0002] eVOTL has the advantages of good economy, comfort, environmental protection and high intelligence, and has great potential in urban air traffic. On the one hand, it can take off and land in a smaller space and does not require a long runway like traditional aircraft. It is suitable for use in city centers or areas with limited space. On the other hand, electric drive is relatively environmentally friendly and has relatively low noise. The applicant designed a new eVOTL with a small airbag, which has good power, long hovering time, low power consumption and high safety.

[0003] As a new type of aircraft, small airships have shown broad application prospects in the fields of sightseeing, environmental monitoring, emergency rescue, etc. Small airships are lighter than air (LTA) aircraft. LTA aircraft use small molecular gases (such as helium) to generate lift. Traditional small airships are mostly streamlined and spindle-shaped. For the mooring of small airships, the prior art CA256536A discloses a mooring station for airships, which has a central mast with internal rigid support and no external pull line, a mast landing line and a connecting device suitable for swinging around the axis of the mast, and a vertical limiting guide that cooperates with the mast device and is suitable for partially or completely swinging around the outside of the tower. The prior art CN101610947A also discloses a lens-shaped airship, but there is no corresponding description of the mooring, release, and recovery of this airship. For this airship, it is generally placed in a boathouse for long-term anchoring. When it is released, it needs to be transported from the warehouse to the release site. When it is recovered, it also needs a special site for landing. The planning and construction period of a boathouse is long, it occupies a large amount of land and space, and it also consumes a lot of money. The construction and maintenance costs are very high. At the same time, anchoring, launching, and recovery operations require a professional team (at least a dozen people) to complete. Not only is the labor cost very high, but manual operation itself increases many operational risks.

[0004] In addition, the existing small airship take-off and landing facilities often cannot meet the needs of small airships for fast and safe take-off and landing. The launch and recovery process of traditional airships has prominent problems such as low efficiency and major safety hazards. Summary of the invention

[0005] The present invention aims to provide a new intelligent launching and retracting platform suitable for eVTOL with small airbags, which can meet the requirements of rapid and safe take-off and landing of eVTOL with small airbags, and can realize efficient, safe and automatic launching, recovery and anchoring management of eVTOL with such airbags.

[0006] The present embodiment provides an intelligent retractable platform for an eVTOL with a small airbag, comprising: a hollow design portion 1 for accommodating the airbag of the eVTOL and a hollow groove portion 21 for accommodating the cabin of the eVTOL, wherein:

[0007] A power-assisted take-off and landing wind tunnel opening 2 is provided at the bottom of the hollow design portion 1, and the power-assisted take-off and landing vent 2 is connected to a high-power blower 4 through a power-assisted take-off and landing wind tunnel pipeline 3;

[0008] The hollow groove portion 21 is located directly below the hollow design portion 1, and the hollow groove portion 21 is connected to the hollow design portion 1;

[0009] At least one lock is provided on the inner wall of the hollow groove 21 for locking with a corresponding lock on the cabin of the eVTOL that falls into the hollow groove 21 .

[0010] Preferably, the table shape and curvature of the bottom of the hollow design portion 1 in contact with the capsule match the shape and curvature of the capsule.

[0011] Preferably, the depth of the hollow design portion 1 is greater than the height of the capsule of the eVTOL.

[0012] Preferably, an openable and closable ceiling 10 is provided on the top of the hollow design portion 1 .

[0013] Preferably, the assisting take-off and landing vent 2 is a large circular through hole, or

[0014] The auxiliary take-off and landing vents 2 are a plurality of arc-shaped through holes.

[0015] Preferably, the lock is an electromagnetic lock or a spring lock.

[0016] Preferably, a liftable adaptive shock-absorbing floor 7 is provided directly below the hollow groove 21 .

[0017] Preferably, a charging and discharging port 8 and a battery maintenance port 9 are also provided at the bottom of the hollow groove 21 .

[0018] Preferably, the intelligent retractable platform is also provided with high-precision radar and laser sensors.

[0019] Preferably, the intelligent retractable platform is also provided with an intelligent host control system for sending corresponding control instructions to the eVTOL according to relevant data of the eVTOL acquired by the high-precision radar and the laser sensor.

[0020] The present invention has the following beneficial effects:

[0021] (1) Different from the existing dedicated boathouses, the intelligent retractable platform for eVTOL with small airbags of the present invention can adapt to different environments and site conditions, including limited space in cities, building roofs, infrastructure-free sites in remote areas, and even trailer compartments, which makes the application range of eVTOL with small airbags wider and can meet more diverse needs;

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the embodiments of the present invention will be described in detail in conjunction with the accompanying drawings hereinafter. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined arbitrarily with each other. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are only illustrative and non-restrictive.

[0029] Figure 1 is a side view of an intelligent retractable platform for eVTOL with a small airbag according to an embodiment of the present invention. Figure 2 It is a top view of an intelligent retractable platform for eVTOL with a small airbag according to an embodiment of the present invention.

[0030] like Figure 1 and Figure 2 As shown, an intelligent retractable platform for eVTOL with a small airbag in this embodiment includes a hollow design part 1 and a hollow groove part 21. The hollow design part 1 is used to accommodate the capsule of the eVTOL. A power-assisted take-off and landing vent 2 is provided at the bottom of the hollow design part 1. The power-assisted take-off and landing vent 2 is connected to a high-power fan or blower 4 through a power-assisted take-off and landing ventilation duct 3. The hollow groove part 21 is used to accommodate the cabin of the eVTOL. The hollow groove part 21 is located directly below the hollow design part 1 and is connected to the hollow design part 1. In this way, when the cabin of the small airship falls, it can pass through the hollow design part 1 and fall into the hollow groove part 21. At least one lock is provided on the inner wall of the hollow groove part 21, which is used to lock with the lock provided on the cabin falling into the hollow groove part 11.

[0031] The hollow design part 1 on the top of the intelligent retractable platform of this embodiment is in the shape of a semi-concave lens (such as a large bowl), which matches the curvature of the lens-shaped (such as a small bowl) eVTOL capsule. The depth of the hollow design part 1 is greater than the height of the capsule of the small airship, which can effectively prevent the capsule from being disturbed by wind and provide stable docking support.

[0032] The intelligent retractable platform of this embodiment uses the principles of hovercraft and wind tunnel. A power-assisted take-off and landing vent 2 is arranged at the bottom of the hollow design part 1 in contact with the eVTOL capsule, and is connected to an external high-power fan / blower 4 through a power-assisted take-off and landing ventilation duct 3. The number of blowers 4 can be configured according to quantity, not limited to those shown in the attached figure. Similar to the power-assisted release, during recovery, the intelligent control system is used to adjust the auxiliary lift during recovery to control the suspension recovery, realizing the suspension lifting control.

[0033] like Figure 2 As shown, the assisted take-off and landing vent 2 of this embodiment is a large circular through hole, and a grid is arranged on the large circular through hole to prevent things from falling.

[0034] In another embodiment, if Figure 3 As shown, the assisted take-off and landing vents 2 may be a plurality of arc-shaped through holes, for example, four, and a grid is arranged on the arc-shaped through holes. Each assisted take-off and landing vent 2 is connected to a blower 4.

[0035] The impact load during the landing process of a traditional airship recovery can easily cause damage to the onboard equipment. In order to reduce the impact of the eVOTL landing impact load, in this embodiment, a liftable adaptive shock-absorbing floor (7) is provided directly below the hollow groove 21.

[0036] In this embodiment, multiple high-power blowers 4 can be used, for example, four 390mm ducted electric power-assisted fans, each of which can achieve a maximum suction or thrust of 75 kg. During takeoff, the reserved annular air outlet in the concave lens-shaped contact surface will assist upward. When the electromagnetic lock is opened, the eVOTL with a small airbag can quickly lift the cabin off the landing platform with the help of the fan, which can reduce the huge loss of battery power during takeoff, thereby extending the flight time.

[0037] The domestic (Yibo) Hang eVOTL, which has just obtained the airworthiness certificate, has only more than 30 kWh of battery power, takes about 10 kWh of power for takeoff and about 10 kWh for landing, and can only stay in the air for 20 to 30 minutes. With the help of the intelligent transceiver platform of this embodiment, the eVTOL with a small helium airbag is lighter during takeoff and landing, greatly reducing the huge loss of battery power during takeoff, thereby extending the air time.

[0038] When necessary, the high-power blower 4 can provide reverse suction force to firmly adsorb the lens-shaped capsule to complete its mooring.

[0039] Optionally, a charging and discharging port 8 and a battery maintenance port 9 are also provided at the bottom of the hollow groove 21 of the platform. The intelligent retractable platform of this embodiment has its own maintenance area and is equipped with an automatic helium charging and discharging device. The eVTOL airbag is inflated or deflated through the charging and discharging port 8. The amount of helium can be automatically adjusted according to demand to ensure the stability of the airbag buoyancy. The design of the battery maintenance port 9 allows for regular inspection, charging and maintenance of the airship's batteries to extend the battery life.

[0040] Optionally, the locks in this embodiment include a first physical lock 5 and a second physical lock 6, and the first physical lock 5 and the second physical lock 6 can lock different parts of the blimp's capsule and cabin.

[0041] A plurality of locks may be provided on the inner wall of the hollow slot 21 of the intelligent transceiver platform of this embodiment, which is not limited to that shown in the embodiment.

[0042] The lock in this embodiment can be an electromagnetic lock or a spring lock. Because the small airbag only provides buoyancy equivalent to lifting a 200-500 kg weight, the weight of the entire eVTOL is much greater than the buoyancy when carrying people, unlike traditional airships which are lighter than air. Because it is heavier than air, the eVTOL with a small airbag in this embodiment can slowly descend to the reserved hole in the middle of the take-off and landing platform under the control of the vector lift propeller and sensors. Once it lands, it will be locked by the electromagnetic lock or spring lock, and the personnel will leave the cabin after stabilization.

[0043] In a preferred embodiment, the top of the hollow design portion 1 may be provided with an openable roof 10 to form a boathouse.

[0044] The intelligent retractable platform of this embodiment may also have a safe evacuation passage 11, which is connected to the annular slide-type sliding door 12. A passenger exchange area and a passage for getting on and off the cabin are also provided in the intelligent retractable platform to provide convenient passenger services, and the slide-type sliding door design for personnel (passengers, maintenance personnel, etc.) to pass through can effectively utilize the platform space.

[0045] The intelligent retractable platform of this embodiment is designed as a lightweight module as a whole and can be moved by a trailer.

[0046] Optionally, the intelligent retraction and deployment platform of the present embodiment also includes high-precision radar and laser sensors (not shown), which can automatically sense the status of the eVOTL with small airbags, and realize autonomous (or remote control) navigation, precise docking and rapid take-off and landing of the eVOTL with small airbags, which greatly reduces the dependence on manual operation and improves safety and efficiency.

[0047] In addition, the intelligent retractable platform host of this embodiment also integrates an intelligent control system, which is used to send corresponding control instructions to the eVOTL according to the relevant data of the eVOTL with small airbags obtained by the high-precision radar and the laser sensor. The intelligent control system of this embodiment also has the following functions: integrating meteorological and environmental monitoring, fault warning, remote monitoring, automatic scheduling and other functions to realize intelligent management of the platform; the platform has built-in AI algorithm to monitor the status of eVOTL in real time, automatically adjust the platform position and mooring mechanism for precise docking and locking; after remote communication between the measurement and control system and the computer loaded on the eVOTL, remote (manual / automatic) control and status monitoring of the eVOTL are realized.

[0048] The above are only preferred embodiments of the present invention. Of course, the present invention may also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
