Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV landing platform. Background Technology

[0002] With the rapid development of science and technology, unmanned aerial vehicles (UAVs) have achieved widespread development and application in both civilian and military fields due to their good stability and strong anti-interference capabilities. For example, the application of UAVs in environmental monitoring, personnel reconnaissance, geographic information collection, and landscape photography is constantly increasing. Although the flight control technology of UAVs is becoming more and more mature, the take-off and landing operation of UAVs in complex environments remains one of the main constraints to their wider and deeper application.

[0003] Especially when drones are inspecting power transmission lines located in mountainous areas or crossing major rivers, the limited battery life of the drones prevents them from flying for extended periods, requiring them to land on a platform for charging or battery swapping. When landing on a platform, drones rely on their own positioning system. However, due to factors such as flight stability, the strong airflow generated by the drone's rotors and its interaction with the ground, and weather conditions, significant landing deviations are common. Summary of the Invention

[0004] Therefore, it is necessary to provide a drone landing platform that can effectively improve the landing accuracy of drones.

[0005] A drone landing platform, comprising:

[0006] Landing base, the landing base having a mounting slot,

[0007] A fixing plate, which is connected to the landing base;

[0008] The sliding plate includes at least one pair, and the two sliding plates of the pair are respectively disposed on opposite sides of the fixed plate. Both sliding plates are slidably connected to the landing base, and a landing area is formed between the two sliding plates and the fixed plate.

[0009] A moving mechanism is disposed in the mounting groove and is connected to the two sliding plates in a transmission manner. The moving mechanism is used to drive the two sliding plates of a pair to move in a direction that is closer to or farther away from the fixed plate.

[0010] In the above scheme, when the drone lands, the moving mechanism drives both sliding plates to move away from the fixed plate, and the drone's support frame lands in the landing area between the sliding plates and the fixed plate. After the drone lands, the two sliding plates are driven to move closer to the fixed plate to adjust the drone's position until the drone's support frame is clamped between the sliding plates and the fixed plate, thereby fixing the drone's position and effectively improving the drone's landing accuracy.

[0011] In one embodiment, the fixing plate includes a first side and a second side, and a third side and a fourth side arranged opposite to each other. The first side and the third side are arranged adjacent to each other, and the second side and the fourth side are arranged adjacent to each other. A sliding plate is provided on the first side, the second side, the third side and the fourth side respectively. The moving mechanism is used to drive the four sliding plates to move in a direction that is closer to or farther away from the fixing plate.

[0012] The mechanism can activate two of the four sliding plates, with the moving mechanism driving these two sliding plates to move closer to or further away from the fixed plate. These two sliding plates can be located on the first and second sides of the fixed plate, or on the third and fourth sides of the fixed plate. Alternatively, all four sliding plates can activate. The moving mechanism 400 drives all four sliding plates 300 to move simultaneously closer to or further away from the fixed plate 200 to accommodate different types of drone landings. Furthermore, the drone does not need to adjust its direction during descent, which can further improve the drone landing efficiency.

[0013] In one embodiment, the fixed plate has a limiting groove with a slot facing the sliding plate on the side near the sliding plate, and the sliding plate has a limiting protrusion that cooperates with the limiting groove on the side near the fixed plate.

[0014] In one embodiment, the limiting groove and the limiting protrusion cooperate to limit the support frame of the drone between the sliding plate and the fixed plate. Both the limiting groove and the limiting protrusion can abut against the support frame of the drone. The limiting protrusion can abut against the support frame within the limiting groove to position the drone between the limiting groove and the limiting protrusion, thereby fixing the drone's position.

[0015] In one embodiment, the length of the limiting groove is greater than the length of the support frame of the drone. By setting the length of the limiting groove to be greater than the length of the support frame of the drone, it is easier to land the drone into the limiting groove.

[0016] In one embodiment, the moving mechanism includes left and right rotating screws, each of which includes a left rotating mechanism, a right rotating mechanism, and a driving part for moving the left rotating mechanism and the right rotating mechanism closer to or further apart from each other. The left rotating mechanism and the right rotating mechanism are respectively fixedly connected to a sliding plate.

[0017] In one embodiment, the left-hand mechanism includes a left-hand lead screw nut, and the right-hand mechanism includes a right-hand lead screw nut. The left-hand lead screw nut and the right-hand lead screw nut are respectively fixedly connected to the sliding plate through a lead screw nut connecting seat.

[0018] In one embodiment, the driving unit includes a lead screw and a driving member for rotating the lead screw. The lead screw includes a left-hand helical part and a right-hand helical part with opposite thread directions. The left-hand lead screw nut is sleeved on the left-hand helical part, and the right-hand lead screw nut is sleeved on the right-hand helical part.

[0019] In one embodiment, the fixing plate is fixedly connected to the mounting groove by a support plate, and the lead screw is rotatably connected to the support plate by a bearing.

[0020] In one embodiment, the mounting groove is recessed into the landing base, and the horizontal height of the plane containing the upper surface of the support plate is lower than that of the upper surface of the landing base.

[0021] The plane containing the upper surface of the fixed plate and the plane containing the upper surface of the sliding plate are on the same horizontal plane. The horizontal height of the plane containing the lower surface of the sliding plate is higher than the horizontal height of the upper surface of the landing base, so as to facilitate the movement of the sliding plate. By setting the horizontal height of the plane containing the upper surface of the support plate to be lower than the horizontal height of the upper surface of the landing base, interference between the sliding plate and the landing base can be effectively avoided, and the landing base does not affect the movement of the sliding plate.

Detailed Implementation

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0035] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0036] Please see Figure 1 and Figure 2This application relates to an unmanned aerial vehicle (UAV) landing platform 10, comprising a landing base 100, a fixed plate 200, a sliding plate 300, and a moving mechanism 400. The fixed plate 200 is connected to the landing base 100, and the sliding plate 300 is slidably connected to the landing base 100, forming a landing area 600 between the fixed plate 200 and the sliding plate 300. The moving mechanism 400 is used to drive the sliding plate 300 to move in a direction closer to or farther from the fixed plate 200, thereby adjusting the position of the UAV landing in the landing area 600 and fixing the position of the UAV.

[0037] The landing base 100 has a mounting groove 110, which is recessed into the landing base 100. The opening of the mounting groove 110 faces upwards. A fixing plate 200 is connected to the mounting groove 110, and a sliding plate 300 is slidably connected to the mounting groove 110 and slidably connected to the edge of the mounting groove 110. The plane containing the upper surface of the fixing plate 200 and the plane containing the upper surface of the sliding plate 300 are on the same horizontal plane.

[0038] Specifically, the fixed plate 200 is fixedly connected to the middle of the mounting groove 110. The sliding plates 300 include at least one pair. In this embodiment, the two sliding plates 300 of the pair are respectively disposed on opposite sides of the fixed plate 200. Both sliding plates 300 are slidably connected to the mounting groove 110, and a landing area 600 is formed between the two sliding plates 300 and the fixed plate 200. The drone includes two spaced-apart support frames, which can land within the landing area 600.

[0039] The fixed plate 200 includes a first side and a second side, and a third side and a fourth side arranged opposite to each other. The first side and the third side are arranged adjacent to each other, and the second side and the fourth side are arranged adjacent to each other. It should be understood that the two sliding plates 300 can be respectively arranged on the first side and the second side of the fixed plate 200, and the two sliding plates 300 can also be respectively arranged on the third side and the fourth side of the fixed plate 200. This application does not limit this.

[0040] Please see Figure 2 , Figure 3 and Figure 4 The moving mechanism 400 is disposed within the mounting groove 110 and is connected to the two sliding plates 300 in a transmission manner. The moving mechanism 400 is used to drive the two sliding plates 300 to move in the direction of approaching or moving away from the fixed plate 200. It should be understood that the two sliding plates 300 move synchronously when moving, that is, the two sliding plates 300 move simultaneously in the direction of approaching or moving away from the fixed plate 200.

[0041] When the drone lands, the moving mechanism 400 drives both sliding plates 300 to move away from the fixed plate 200, and the drone's support frame lands within the landing area 600 between the sliding plates 300 and the fixed plate 200. After landing, the two sliding plates 300 are driven to move closer to the fixed plate 200 to adjust the drone's position until the drone's support frame is clamped between the sliding plates 300 and the fixed plate 200, thereby fixing the drone's position and effectively improving the drone's landing accuracy.

[0042] When the two sliding plates 300 move to their maximum position away from the fixed plate 200, the landing area 600 formed between the fixed plate 200 and the sliding plates 300 is at its maximum, facilitating the drone's landing within this area. After the drone lands, if its landing position deviates, the two sliding plates 300 need to be moved closer to the fixed plate 200 to adjust its landing position. When the two sliding plates 300 move to their maximum position closer to the fixed plate 200, the drone is clamped between the sliding plates 300 and the fixed plate 200. At this point, the drone's position is fixed and within the set position.

[0043] It should be understood that the fixing plate 200 can be a square structure or a rectangular structure, and this application does not limit it. The length and width of the fixing plate 200 are both smaller than the distance between the two support bases of the UAV, so that the two support bases of the UAV are located on opposite sides of the fixing plate 200.

[0044] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, a sliding plate 300 is provided on the first side, the second side, the third side, and the fourth side, and the moving mechanism 400 is used to drive all four sliding plates 300 to move in a direction closer to or farther from the fixed plate 200. In this embodiment, the number of sliding plates 300 is four. And the plane on which the upper surface of the four sliding plates 300 is located is on the same horizontal plane as the plane on which the upper surface of the fixed plate 200 is located.

[0045] It's important to understand that the drone's support frame can have two or four components. When there are two support frames, two of the four sliding plates 300 are activated, and the moving mechanism 400 drives these two sliding plates 300 to move towards or away from the fixed plate 200. These two sliding plates 300 can be located on the first and second sides of the fixed plate 200, or on the third and fourth sides, to accommodate different types of drone landings. Furthermore, during descent, the drone does not need to adjust its direction; it only needs to land between the first and second sides of the fixed plate 200 or between the third and fourth sides, further improving landing efficiency.

[0046] When there are four supporting base frames, the moving mechanism 400 drives the four sliding plates 300 to move simultaneously in a direction closer to or farther from the fixed plate 200. In this embodiment, the moving mechanism 400 includes two left and right rotating lead screws, each of which includes a left rotating mechanism, a right rotating mechanism, and a driving part for driving the left rotating mechanism and the right rotating mechanism closer to or farther from each other.

[0047] The left-hand and right-hand mechanisms of one of the two left-hand and right-hand lead screws are respectively fixedly connected to two of the four sliding plates 300. The left-hand and right-hand mechanisms of the other left-hand and right-hand lead screw are respectively fixedly connected to the other two sliding plates 300. Specifically, the left-hand mechanism includes a left-hand lead screw nut 410, and the right-hand mechanism includes a right-hand lead screw nut 420. The left-hand lead screw nut 410 and the right-hand lead screw nut 420 are respectively fixedly connected to the sliding plates 300 through lead screw nut connecting seats.

[0048] Please see Figure 2 , Figure 3 and Figure 4 According to some embodiments of this application, optionally, the fixed plate 200 has a limiting groove 210 with its opening facing the sliding plate 300 on the side near the fixed plate 200, and the sliding plate 300 has a limiting protrusion 310 that cooperates with the limiting groove 210 on the side near the fixed plate 200. The limiting groove 210 and the limiting protrusion 310 cooperate with each other to limit the support frame of the UAV between the limiting groove 210 and the limiting protrusion 310, and both the limiting groove 210 and the limiting protrusion 310 can abut against the support frame of the UAV.

[0049] Specifically, the length of the limiting groove 210 is greater than the length of the drone's support frame, allowing the drone's support frame to be accommodated within the limiting groove 210. Furthermore, the limiting protrusion 310 can abut against the support frame within the limiting groove 210, thereby positioning the drone between the limiting groove 210 and the limiting protrusion 310, thus fixing the drone's position. It should be understood that this application does not limit the depth (i.e., length) of the limiting groove 210; it can be set according to actual usage requirements, as long as it satisfies the need for the support frame to be accommodated within the limiting groove 210 and to be able to move within it.

[0050] By setting the length of the limiting groove 210 to be greater than the length of the drone's support frame, it is easier to land the drone into the limiting groove 210.

[0051] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the moving mechanism 400 includes left and right rotating screws, the left and right rotating screws include a left rotating mechanism, a right rotating mechanism, and a driving part for driving the left rotating mechanism and the right rotating mechanism to move closer or further apart from each other, and the left rotating mechanism and the right rotating mechanism are respectively fixedly connected to a sliding plate 300.

[0052] Specifically, the left-hand mechanism includes a left-hand lead screw nut 410, and the right-hand mechanism includes a right-hand lead screw nut 420. The left-hand lead screw nut 410 and the right-hand lead screw nut 420 are respectively fixedly connected to the sliding plate 300 through lead screw nut connecting seats.

[0053] Please see Figure 1 , Figure 2 and Figure 3 The drive unit includes a lead screw 430 and a drive component 440 for rotating the lead screw 430. The lead screw 430 includes a left-hand helical portion and a right-hand helical portion with opposite thread directions. A left-hand lead screw nut 410 is fitted onto the left-hand helical portion, and a right-hand lead screw nut 420 is fitted onto the right-hand helical portion. The lead screw 430 is mounted in the mounting groove 110 via a bearing and a bearing mounting seat 450.

[0054] The drive component 440 drives the lead screw 430 to rotate, which in turn causes the left-hand lead screw nut 410 and the right-hand lead screw nut 420 to move closer or further apart, thereby causing the two sliding plates 300 to move closer or further apart. The drive component 440 is a motor. The horizontal height of the plane containing the upper surface of the drive component 440 is lower than the upper surface of the landing base 100 to avoid interference with the sliding plates 300.

[0055] Please see Figure 1 , Figure 2 and Figure 3According to some embodiments of this application, optionally, the fixing plate 200 is fixedly connected to the mounting groove 110 via the support plate 700, and the lead screw 430 is rotatably connected to the support plate 700 via bearings. Specifically, the lead screw 430 further includes a support portion disposed between the left-hand helical portion and the right-hand helical portion. The support plate 700 is provided with the mounting groove 110, and the support portion is rotatably connected to the mounting groove 110 via bearings.

[0056] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the horizontal height of the plane containing the upper surface of the support plate 700 is lower than the horizontal height of the upper surface of the landing base 100. It should be understood that the plane containing the upper surface of the fixed plate 200 and the plane containing the upper surface of the sliding plate 300 are on the same horizontal plane, and the horizontal height of the plane containing the lower surface of the sliding plate 300 is higher than the horizontal height of the upper surface of the landing base 100, so as to facilitate the movement of the sliding plate 300.

[0057] By setting the horizontal height of the plane containing the upper surface of the support plate 700 to be lower than the horizontal height of the upper surface of the landing base 100, interference between the sliding plate 300 and the landing base 100 can be effectively avoided, and the landing base 100 will not affect the movement of the sliding plate 300.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
