Description

Technical Field

[0001] The present application belongs to the field of air transportation, and in particular relates to an aircraft take-off and landing platform. Background Art

[0002] The background description provided here is used to generally introduce the background of this application. The work of the presently named inventors described in this background section to the extent that it does not constitute prior art at the time of filing is neither explicitly nor implicitly admitted to be prior art that conflicts with this application.

[0003] With the comprehensive development of the low-altitude economy, vertical take-off and landing (VTOL) aircraft, as one of its core technological paths, are receiving significant attention. The core mechanism for achieving VTOL is the use of a multi-rotor system. This system operates by rotating multiple rotors at high speed, causing rapid and non-uniform dynamic changes in the air beneath the fuselage, thereby providing lift for the aircraft and enabling smooth takeoff and landing. However, during this process, when the aircraft approaches the ground, the airflow beneath it is obstructed by the ground, triggering ground effect. This ground effect disrupts the stability of the airflow beneath the aircraft, threatening the smoothness and safety of the aircraft during takeoff and landing.

[0004] Chinese patent publication CN117622569A discloses a drone landing platform, comprising: a first platform frame and a second platform frame stacked and spaced apart. A first support cloth is detachably mounted on the side of the first platform frame facing away from the second platform frame to form a first plane, the first support cloth having a plurality of air holes. A second support cloth is detachably mounted on the side of the second platform frame facing the first platform frame to form a second plane. The orthographic projection of the second support cloth along a first direction at least completely covers the first support cloth. The first direction is the direction in which the first and second platform frames are stacked. A support assembly is detachably mounted on the side of the second platform frame facing away from the first platform frame to support the support surface of the drone landing platform. The first support cloth is capable of transmitting airflow downward through the air holes while providing stable support for the drone, and then discharging it through the gap between the first and second support cloths to prevent ground effect. However, this structure is relatively complex, and the airflow exhaust efficiency is not high enough. Therefore, a new aircraft landing platform is needed. Utility Model Content

[0024] The following description is merely exemplary in nature and is not intended to limit the present application, applications, or uses. Furthermore, no intention is made to be bound by any expressed or implied theory presented in the preceding technical field, background, and utility model disclosure, or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals identify similar or corresponding parts or features.

[0025] The present application will now be further described. In the following paragraphs, different aspects of the present application are defined in more detail. Unless expressly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as preferred or advantageous may be combined with any other feature(s) indicated as preferred or advantageous.

[0026] In view of the problems existing in the prior art, this application provides a new aircraft take-off and landing platform that can effectively prevent the ground effect. Figure 1 , shows an aircraft take-off and landing platform 100 according to the principles of the present application. The aircraft take-off and landing platform 100 includes a carrying platform 110 and a support structure 120, wherein the carrying platform 110 is used to carry an aircraft so that the aircraft can take off or land on it. The support structure 120 is connected to the side of the carrying platform 110 facing the ground so as to support the carrying platform 110, thereby supporting the carrying platform 110 above the ground. Figure 1 , Attachment Figure 2 and attached Figure 4, the carrying platform 110 is provided with a grid structure 112 composed of a plurality of grid units 111. In one embodiment, the grid structure 112 is provided on the outside or outer ring of the carrying platform 110, that is, in a direction close to the edge of the carrying platform 110. In one embodiment, the carrying platform 110 is constructed as a grid structure 112 composed of a plurality of grid units 111, that is, the carrying platform 110 as a whole is a grid structure 112, which can both enhance the exhaust performance and reduce the weight of the carrying platform. It should be understood that in actual applications, a suitable carrying platform can be selected according to factors such as the installation position and size of the aircraft rotor. Due to the presence of the grid structure, the exhaust performance of the carrying platform is greatly enhanced, so that when the aircraft takes off and lands on the carrying platform 110, the airflow generated by the aircraft rotor under the aircraft can flow out from the space between the carrying platform 110 and the ground through the grid structure 112, thereby effectively reducing the ground effect.

[0027] The carrying platform 110 according to the principles of the present application can be of any shape. In some embodiments, the carrying platform 110 is circular, or a polygon such as a rectangle, pentagon, hexagon, heptagon or octagon. In some embodiments, the carrying platform 110 is preferably circular, hexagonal or octagonal, so as to facilitate the landing of the aircraft and avoid the aircraft from making unnecessary turns to adapt to the shape of the carrying platform during landing. In some embodiments, the carrying platform 110 is preferably a square, a regular pentagon, a regular hexagon, a regular heptagon or a regular octagon. Preferably, the diameter of the circumscribed circle of the carrying platform 110 when it is a polygon such as a hexagon or rectangle is greater than twice the diameter of the circumscribed circle of the aircraft, so that the carrying platform 110 has a sufficiently large take-off and landing area to facilitate the take-off and landing of the aircraft.

[0028] It should be understood that the ground in this application generally refers to the surface supporting the take-off and landing platform, which can be the ground surface or other surfaces, such as surfaces provided on buildings, vehicles, ships, etc.

[0029] Refer to the attached Figure 3 and attached Figure 4The grille unit 111 includes a first wall 113 and a second wall 114. The first wall 113 extends along a direction passing through the geometric center of the support platform 110. For example, for a circular support platform 110, the first wall 113 extends radially. The second wall 114 extends circumferentially around the support platform 110. For example, for a circular support platform 110, the second wall 114 may be an arc concentric with the circle. For a hexagonal or other polygonal support platform 110, the second wall 114 may be a straight line parallel to at least one side of the support platform 110. The first wall 113 and the second wall 114 are interconnected to form the grille unit 111. Advantageously, the lower portion of the second wall 114, i.e., the end closest to the ground, is inclined outward from the support platform 114. This allows airflow generated beneath the aircraft during takeoff and landing to flow along the grille unit 111 toward the outside of the support platform 110, reducing air accumulation on the support platform 110 and further minimizing ground effect. This also facilitates the drainage of rainwater during rainy weather.

[0030] Refer to the attached Figure 4 Advantageously, in some embodiments, the horizontal projections of the second walls 114 of the multiple grille units 111 partially overlap. For example, the horizontal projection of the second wall 114a of grille unit 111a is a, and the horizontal projection of the second wall 114b of grille unit 111b is b. Projections a and b partially overlap at c. This prevents the ground from being visible when looking directly above or below the support platform 110, thereby preventing people on the support platform 110 from developing a fear of heights. Furthermore, it prevents dust stirred up by airflow from floating upward into the aircraft, ensuring the cleanliness of the aircraft.

[0031] Preferably, refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 5The aircraft landing platform 100 may also be provided with a lifting platform 130 at its center, such that the carrying platform 110 surrounds the lifting platform 130. Advantageously, the lifting platform 130 has the same shape as the landing platform 100. For example, in the exemplary embodiment shown, both the lifting platform 130 and the landing platform 100 are regular hexagonal in shape. Alternatively, both the lifting platform 130 and the landing platform 100 may be circular in shape, as will be readily understood by those skilled in the art. The top surface 131 of the lifting platform 130 can be raised and lowered to be flush with the top surface of the carrying platform 110 to facilitate the transportation of passengers or cargo. The lifting platform 130 can be used to transport cargo or passengers. For example, before an aircraft takes off, the lifting platform 130 can be used to transport passengers or cargo from the ground to the carrying platform 110 for departure. After the aircraft lands, the lifting platform 130 can be used to transport passengers or cargo back to the ground, thereby improving transportation efficiency. The lifting platform 130 can be of various types, such as a hydraulic lift, a screw lift, or a chain lift, and this application is not limited thereto. Advantageously, the top surface 131 of the lifting platform or the supporting platform 110 can be painted with a visual identification mark so that the aircraft can locate the take-off and landing platform based on this mark. The visual identification mark can be letters, numbers, or patterns, or a combination thereof.

[0032] In some embodiments, the lifting platform 130 may be equipped with a charging device (not shown). When an aircraft lands on the take-off and landing platform 100, the lifting platform 130 can be raised above the take-off and landing platform 100 to charge the aircraft. The charging device can be either a wired or wireless charging device. In some embodiments, the charging device is a wireless charging device and can be installed on the top surface of the lifting platform 130, allowing the lifting platform 130 to be raised to a height that contacts the aircraft, such as a height that contacts the aircraft's belly, to wirelessly charge the aircraft. In some embodiments, the charging device is a wired charging device, which can be installed on the top surface or side of the lifting platform 130 and charges the aircraft via a charging cable. In these embodiments, the lifting platform 130 can be raised to any suitable charging height, without having to be raised to a height that allows contact with the aircraft.

[0033] Refer to the attached Figure 1 and attached Figure 5The aircraft landing platform 100 may also include a safety net 140. The safety net 140 surrounds the support platform 110, and the top of the safety net 140, i.e., the end of the safety net 140 away from the ground, is tilted away from the landing platform 130, thereby preventing objects on the landing platform 100 from falling to the ground and causing safety accidents. The safety net 140 is detachably connected to the support platform 140 and / or the support structure 120 via bolts or clips for easy removal. Advantageously, in some embodiments, the top of the safety net 140 is no higher than the support platform 110, thereby avoiding interference with the aircraft taking off and landing.

[0034] Refer to the attached Figure 1 and attached Figure 5 The support structure 120 may include a support beam 121 and a support column 122, wherein the support beam 121 is connected to the carrying platform 110 in the horizontal direction to increase the contact area with the carrying platform 110, and wherein the support column 122 is connected to the support beam 121 in the vertical direction, thereby providing support for the support beam 121 and the entire carrying platform 110. This structure makes the support of the supporting structure 120 to the carrying platform 110 more stable. In some embodiments, the support beam 121 extends in the horizontal direction in a direction passing through the geometric center of the carrying platform 110, thereby reducing the impact on the exhaust performance of the grille structure 112. In some embodiments, wheels may be provided at the bottom of the support column 121 to facilitate the movement of the lifting platform.

[0035] The aircraft landing platform based on the principles of this application can be used for both manned and unmanned aircraft, and can be installed on the ground, in buildings, on vehicles, on ships, etc., to adapt to a variety of application scenarios. The size of the aircraft landing platform can be determined according to the size of the aircraft it is adapted to.

[0036] The aircraft take-off and landing platform based on the principles of this application can effectively discharge the airflow generated below the aircraft during take-off and landing through the grille structure, thereby effectively preventing ground effect and ensuring smooth take-off and landing. In addition, the aircraft take-off and landing platform of this application also has excellent drainage, dust prevention, and acrophobia relief functions, making it suitable for a variety of application scenarios.

It should also be understood that the exemplary embodiment or embodiments described herein are merely examples and are not intended to limit the scope, applicability, or configuration of the present application in any way.
