Description

Technical Field

[0001] This application relates to the field of engineering equipment technology, and more specifically, to a calibration platform for unmanned aerial vehicles (UAVs). Background Technology

[0002] With the rapid development of drone technology, drones have been widely used in agriculture, logistics, surveying, monitoring, rescue, and many other fields. During mission execution or recovery, drones typically require multiple adjustments and calibrations to ensure stability and accuracy during takeoff, flight, and landing. Current drone adjustment equipment is usually operated manually, which is not only time-consuming and labor-intensive but also susceptible to human error, leading to insufficient adjustment accuracy. Furthermore, some adjustment platforms use single-direction or simple mechanical structures, failing to meet the multi-directional adjustment needs of drones with complex geometries, thus limiting their applicability and efficiency.

[0003] Therefore, there is an urgent need for a new calibration platform for unmanned aerial vehicles (UAVs). Utility Model Content

[0004] The purpose of this application is to provide an adjustment platform for unmanned aerial vehicles (UAVs), which can adjust the horizontal position of the UAV when it is docked on the platform body through a centering mechanism, and then adjust the direction of the UAV's propellers through a lever mechanism, thereby ensuring the accuracy of the UAV's docking position after recovery and ensuring that the UAV can take off smoothly when it performs another mission.

[0017] In some embodiments of this application, the width of the first pair of push rods is greater than the width of the second pair of push rods, and the first pair of push rods and the second pair of push rods are independent of each other and do not contact each other.

[0018] In some embodiments of this application, the centering mechanism further includes a plurality of lifting and lowering limit plates, which are arranged on the platform body and correspond to the end positions of the first lead screw and / or the second lead screw.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] In the description of the embodiments of this application, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they 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 on this application. In addition, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted.

[0040] The drone calibration platform provided in this application can be used for drone parking, takeoff, and accessory installation. In practical applications, it can be adapted to different types of drones for use in various fields such as agriculture, logistics, surveying, monitoring, and rescue. The drone calibration platform will be described in detail below.

[0041] Figure 1 This is a schematic diagram of the structure of an adjustment platform 100 for a drone provided in one embodiment of this application; Figure 2 A top view of an adjustment platform 100 for an unmanned aerial vehicle provided in an embodiment of this application; Figure 3 One of the side views of an adjustment platform 100 for a drone provided in an embodiment of this application; Figure 4 A second side view of an adjustment platform 100 for a drone provided in an embodiment of this application; Figure 5 This is a schematic diagram of the structure of the lever 111 provided in one embodiment of this application; Figure 6 This is another structural schematic diagram of the adjustment platform 100 for a drone provided in one embodiment of this application. (See attached diagram.) Figures 1-6 As shown, the adjustment platform 100 for the UAV may include a platform body 10, a centering mechanism, and a lever 111 mechanism. The centering mechanism includes a first centering unit and a second centering unit, the first centering unit being positioned along a first preset direction (e.g., ...). Figure 2 The second centering unit is slidably mounted on the platform body 10 in the direction shown, and the second centering unit is positioned along the second preset direction (e.g., the direction shown). Figure 2The lever 111 mechanism (shown in the direction) is slidably disposed on the platform body 10; the lever 111 mechanism includes a lever 111 and a drive unit 113, the lever 111 can rotate in a first preset plane under the drive of the drive unit 113; wherein, the first preset direction and the second preset direction are not parallel to each other, and neither the first preset direction nor the second preset direction is in the first preset plane.

[0042] It should be understood that in this embodiment, the first preset plane refers to a vertical plane, while the first preset direction and the second preset direction refer to two directions of a horizontal plane. Therefore, neither the first preset direction nor the second preset direction is within the first preset plane.

[0043] It is worth noting that in this embodiment, the first preset direction and the second preset direction are not parallel to each other, but they cooperate to push the drone 200 docked on the platform body 10 to the preset work position (e.g., Figure 1 (as shown in the workstation), and then through the lever 111 mechanism, the propellers of the UAV 200 are aligned to the preset position (such as...). Figure 1 (as shown in the image), thereby ensuring the accuracy of the docking location of the UAV 200 after recovery, and ensuring that the UAV 200 can take off smoothly when it performs another mission.

[0044] It is also worth noting that the precise adjustment in both directions can shorten the time it takes for the UAV 200 to go from docking to positioning at the work station, providing rapid preparation for the UAV 200 to take off again to perform tasks. The non-parallel adjustment of the directions can accurately eliminate the initial position deviation of the UAV 200, avoiding the cumulative error that may be introduced by traditional single-direction or planar adjustment.

[0045] like Figure 3 As shown, the lever 111 mechanism also includes a centering base plate 112, which is mounted on the platform body 10; the drive unit 113 is an electric push rod, one end of which is connected to the centering base plate 112 and the other end of which is connected to the lever 111. One end of the lever 111 is rotatably connected to the centering base plate 112, and the free end of the lever 111 is used to center the UAV 200.

[0046] It is worth noting that the free end of the lever 111 is used to align the UAV 200. It can directly act on the propellers or other structural parts of the UAV 200 to adjust them to a preset position, ensuring that the attitude of the UAV 200 is precisely aligned with the docking position required for the mission. The rotating connection design of the lever 111, combined with the linear drive of the electric push rod, allows it to rotate flexibly within a first preset plane, achieving fine-tuning and thus adapting to different models or states of the UAV 200.

[0047] like Figure 5As shown, the lever 111 includes a centering part 1111, a connecting part 1112, and a rotating part 1113. The connecting part 1112 has a straight strip structure, and the rotating part 1113 is located in the middle of the connecting part 1112. The side of the rotating part 1113 away from the connecting part 1112 is connected to the electric push rod.

[0048] It is worth noting that the straight-line connecting part 1112 ensures that the force transmission direction of the lever 111 is clear and stable, so that the lever 111 can act more accurately on the propeller or other structure of the UAV 200. The rotating part 1113 is located in the middle of the connecting part 1112, so that the lever 111 can rotate flexibly with the rotating part 1113 as the fulcrum, thereby achieving a large range of adjustment to meet the alignment requirements of different UAVs 200.

[0049] In this embodiment, one end of the connecting part 1112 is connected to the straightening base plate 112, and the other end is connected to the straightening part 1111. The straightening part 1111 is "V" shaped, and the opening of the straightening part 1111 is opposite to the connecting part 1112.

[0050] It is worth noting that the "V"-shaped design of the alignment part 1111 allows it to be compatible with propellers or fuselage components of the UAV 200 of different sizes and shapes. During alignment, the two sides of the "V" shape can naturally conform to the surface of the UAV 200 components, reducing the precision requirements of the contact position and improving operational adaptability. At the same time, the structure of the opening facing away from the connecting part 1112 ensures that the lever 111 can smoothly cover or contact the UAV 200 components during alignment, reducing the risk of misalignment or incomplete adjustment.

[0051] Please refer to this again. Figure 3 and Figure 4 The first centering unit includes a first pair of positive push rods 121, a first alignment support plate 122, a first lead screw nut 123, a first lead screw 124, and a first motor 125. The output end of the first motor 125 is connected to the first lead screw 124. The first lead screw nut 123 is threadedly connected to the first lead screw 124 and can move along a first preset direction by rotating the first lead screw 124. The first pair of positive push rods 121 are connected to the first lead screw nut 123 through the first alignment support plate 122. The second centering unit includes a second pair of positive push rods 131, a second alignment support plate 132, a second lead screw nut 133, a second lead screw 134, and a second motor 135. The output end of the second motor 135 is connected to the second lead screw 134. The second lead screw nut 133 is threadedly connected to the second lead screw 134 and can move along a second preset direction by rotating the second lead screw 134. The second pair of positive push rods 131 are connected to the second lead screw nut 133 through the second alignment support plate 132.

[0052] It is worth noting that the threaded connection structure of the lead screw and lead screw nut ensures smooth movement of the push rod during adjustment, featuring high transmission and positioning accuracy. By driving the lead screw to rotate via the first motor 125 and the second motor 135 respectively, rapid adjustment of the UAV 200's position can be achieved, shortening the time required to center the UAV 200 and improving operational efficiency.

[0053] In some embodiments of this application, the width of the first pair of positive push rods 121 is greater than the width of the second pair of positive push rods 131, and the first pair of positive push rods 121 and the second pair of positive push rods 131 are independent of each other and do not contact each other.

[0054] It is worth noting that the first pair of positive push rods 121 are wider, which provides a larger contact area during adjustment, enhances the stability of thrust transmission, and is suitable for handling larger adjustment needs in the first preset direction, for example, as... Figure 1 As shown, it can simultaneously push both legs of the drone 200. The second pair of positive push rods 131 is narrower and more flexible, allowing for precise adjustment of the position in the second preset direction. Furthermore, the width settings of the first pair of positive push rods 121 and the second pair of positive push rods 131 allow them to operate independently without contact, avoiding positional shifts caused by contact or interference during adjustment and improving the accuracy of adjusting the drone 200 to the predetermined position.

[0055] It should be understood that, in actual use, the drone 200 can first dock at any position on the platform body 10. At this time, the first pair of positive push rods 121 push it to the center position in the first preset direction. Then the second pair of positive push rods 131 push it to the aforementioned preset position (e.g., Figure 1 (The workstation shown). Finally, adjust the propeller orientation of the UAV 200 using lever 111.

[0056] In this embodiment, the centering mechanism also includes a plurality of lifting and lowering limit plates 14, which are arranged on the platform body 10 and correspond to the end positions of the first lead screw 124 and / or the second lead screw 134.

[0057] Understandably, the lifting limit plate 14 is located at the end of the lead screw, which can effectively limit the maximum stroke of the push rod, prevent the push rod from exceeding the design range, and avoid mechanical damage caused by excessive movement. In addition, by physically limiting the position, structural conflicts or jamming caused by excessive push rod movement can be avoided when the motor control fails, thus improving the operational safety of the equipment.

[0058] In this embodiment, there are two pairs of first-pair positive push rods 121 and two pairs of second-pair positive push rods 131. The two first-pair positive push rods 121 are arranged facing each other on both sides of the first lead screw 124, and the two second-pair positive push rods 131 are arranged facing each other on both sides of the second lead screw 134.

[0059] Optionally, the first preset direction and the second preset direction are perpendicular to each other.

[0060] Specifically, the first preset direction and the second preset direction are perpendicular to each other, ensuring that adjustments in the two directions do not interfere with each other. This allows for more precise adjustment of the UAV 200 to the target workstation, avoiding offset or cross-interference. The vertical orientation reduces the need for complex adjustment calculations and lowers the motion vector decomposition error caused by the non-orthogonal layout.

[0061] like Figure 6 As shown, the adjustment platform 100 for the UAV also includes a lifting mechanism, which includes a lifting platform 151 and a ball screw lift 152. The platform body 10 is arranged on one side of the lifting platform 151 and the ball screw lift 152 is arranged on the other side. The platform body 10 can move along a third preset direction through the lifting mechanism. The first preset direction, the second preset direction and the third preset direction are not parallel to each other.

[0062] It is worth noting that the lifting mechanism can work in conjunction with the centering mechanism and the lever 111 mechanism to form a complete automatic adjustment system for the UAV 200. This system enables fully automatic adjustment of the UAV 200 from recovery to docking, significantly reducing manual intervention and improving work efficiency. Simultaneously, precise three-dimensional adjustment ensures standardized docking of the UAV 200, providing a precise positional basis for subsequent takeoff, charging, and maintenance.

[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
