Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) radar, and in particular to a UAV radar pod structure. Background Technology

[0002] In the aviation field, UAVs vary greatly in size, payload capacity, and interface standards, while radar weight, volume, and power consumption also differ significantly due to functional differences. Pod design breaks the "one UAV, one radar" constraint, enabling cross-platform compatibility: Small UAVs (such as multi-rotor and lightweight fixed-wing aircraft) have extremely limited internal space, making it impossible to accommodate radar antennas, signal processing units, and other components; even for large UAVs, internal space must be prioritized for core systems such as flight control, fuel, and navigation. Pods utilize external space by being "externally mounted," without occupying internal core areas, significantly reducing the design complexity of UAVs. Balanced payload weight distribution: The weight of radar (especially high-power radar) is concentrated in the antenna and power module; integrating it internally could cause the UAV's center of gravity to shift, affecting flight stability. Pods, through symmetrical mounting (such as on the sides of the wings) or optimized mounting positions (such as on the fuselage belly), can flexibly adjust weight distribution to meet the payload balance requirements of UAVs.

[0003] Existing drone pods used to carry lidar mostly rely on pre-installed metal brackets on the fuselage to fix the pod to the drone via docking rings or flanges to ensure a tight connection. During installation, multiple anchoring and installation operations are required to ensure the stability of the pod. Since the docking rings or flanges need to be fixed with bolts or other tools, the installation operations at multiple points are time-consuming, affecting the efficiency of installation and disassembly operations. Utility Model Content

[0004] To address the aforementioned issues, this application provides a UAV radar pod structure.

[0005] To achieve the above objectives, this application provides the following technical solution: a drone radar pod structure, including a drone and a lidar located below the drone. A docking sleeve is fixed to the bottom of the drone shell. Multiple limiting rods are equidistantly distributed along a circumferential trajectory on the outer periphery of the docking sleeve. A gimbal is fixed on the lidar. Multiple docking protrusions are fixed to the surface of the gimbal and are equidistantly distributed along a circumferential trajectory. Each docking protrusion has a docking hole adapted to the limiting rod. When the gimbal is inserted into the docking sleeve, the multiple docking protrusions are inserted into the multiple limiting rods through the docking holes.

[0006] It also includes multiple arc-shaped limiting strips that are equidistantly distributed along a circular trajectory. These multiple arc-shaped limiting strips can rotate synchronously. When the mating protrusion is inserted into the limiting rod through the mating hole, the multiple arc-shaped limiting strips are located below the mating protrusion, and the multiple arc-shaped limiting strips pass through the multiple limiting rods respectively.

[0007] Furthermore, the bottom of the drone shell is fixed with a protective sleeve and a positioning flange. The docking sleeve and the limiting rod are both fixed to the positioning flange, and the docking sleeve and the positioning flange are located inside the protective sleeve. The bottom end of the limiting rod passes through the protective sleeve and extends below it. When the gimbal is inserted into the docking sleeve, the gimbal passes through the center of the protective sleeve, and the docking protrusion is located below the protective sleeve.

[0008] Furthermore, a rotatable drive gear ring is installed on the outside of the docking sleeve. The drive gear ring meshes with multiple linkage gears that are equidistantly distributed along a circumferential trajectory. Each linkage gear has a linkage shaft fixed at its central axis that can rotate synchronously with it. The bottom end of the linkage shaft passes through the sheath and extends below it. Multiple arc-shaped limiting strips are respectively fixed to the bottom ends of the multiple linkage shafts. When the docking protrusion is inserted into the limiting rod through the docking hole, the arc-shaped limiting strip rotates below the docking protrusion until it passes through the limiting rod.

[0009] Furthermore, a drive gear is installed at the bottom of the drone shell. The drive gear meshes with a drive gear ring, and the drive gear is located inside the protective sleeve. As the drive gear rotates, the drive gear ring rotates synchronously.

[0010] Furthermore, a driver capable of rotating is installed at the central shaft position of the drive gear. The driver is installed inside the drone housing, and when the drive gear rotates, the drive ring rotates synchronously.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] This invention creates multiple evenly distributed docking points beneath the drone, improving the tightness and stability of the docking between the gimbal, lidar, and docking sleeve. Furthermore, multiple points can be locked simultaneously, preventing the lidar from shaking or shifting during drone flight. This reduces the time required for individual point operations, improves installation portability, and ultimately enhances the efficiency of pod installation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Reference Figure 1-3 The diagram shows a UAV radar pod structure, including a UAV 1 and a lidar 2 located below the UAV 1. A docking sleeve 31 is fixed to the bottom of the UAV 1 shell. Multiple limiting rods 33 are equidistantly distributed along a circumferential trajectory on the outer periphery of the docking sleeve 31. A gimbal 21 is fixed on the lidar 2. Multiple docking protrusions 22 are fixed on the surface of the gimbal 21, equidistantly distributed along a circumferential trajectory. Each docking protrusion 22 has a docking hole 23 that matches the limiting rods 33. When the gimbal 21 is inserted into the docking sleeve 31, the multiple docking protrusions 22 are inserted into the multiple limiting rods 33 through the docking holes 23, forming multiple evenly distributed docking points. This improves the tightness and stability of the gimbal 21 and the lidar 2 in the docking state with the docking sleeve 31, thereby enabling the lidar 2 to stably perform detection operations as the UAV 1 flies.

[0023] It also includes multiple arc-shaped limiting strips 6 evenly distributed along a circular trajectory. When the docking protrusion 22 is inserted into the limiting rod 33 through the docking hole 23, the multiple arc-shaped limiting strips 6 can rotate synchronously below the docking protrusion 22, and pass through the multiple limiting rods 33 respectively. The connection between the arc-shaped limiting strips 6 and the limiting rods 33 can lock the multiple docking protrusions 22, so as to achieve the purpose of simultaneously locking multiple points, and avoid the docking protrusion 22, the gimbal 21 and the lidar 2 from shaking or deviating during the flight of the UAV 1.

[0024] Furthermore, in this invention, since multiple arc-shaped limiting strips 6 can rotate synchronously below the docking protrusion 22, locking operations of multiple docking points can be performed simultaneously, reducing the time required for operation at each point individually, improving installation portability, and thus improving the efficiency of pod installation operations.

[0025] Specifically, such as Figure 3 , Figure 4 As shown, a protective sleeve 11 and a positioning flange 3 are fixed to the bottom of the UAV 1 shell. The docking sleeve 31 and the limiting rod 33 are both fixed to the positioning flange 3, and the docking sleeve 31 and the positioning flange 3 are located inside the protective sleeve 11. The bottom end of the limiting rod 33 passes through the protective sleeve 11 and extends below it. When the gimbal 21 is inserted into the docking sleeve 31, the gimbal 21 passes through the center of the protective sleeve 11, and the docking protrusion 22 is located below the protective sleeve 11. The protective sleeve 11 can prevent impurities from entering the insertion position of the gimbal 21 and the docking sleeve 31, ensuring the smoothness of the docking and separation process of the gimbal 21 and the docking sleeve 31.

[0026] like Figure 4 , Figure 5 As shown, a rotatable drive gear ring 32 is installed on the outside of the docking sleeve 31. The drive gear ring 32 is meshed with multiple linkage gears 4 that are equidistantly distributed along a circumferential trajectory. Each linkage gear 4 has a linkage shaft 5 fixed at its central shaft position that can rotate synchronously with it. The bottom end of the linkage shaft 5 passes through the protective sleeve 11 and extends below it. Multiple arc-shaped limiting strips 6 are fixed to the bottom ends of the multiple linkage shafts 5 respectively. When the docking protrusion 22 is inserted into the limiting rod 33 through the docking hole 23, as the drive gear ring 32 rotates, the multiple linkage gears 4 and the linkage shafts 5 connected to them rotate synchronously. This allows the multiple arc-shaped limiting strips 6 to rotate below the docking protrusion 22 until they pass through the limiting rod 33, thereby achieving the purpose of locking multiple docking points simultaneously.

[0027] like Figure 6As shown, in order to provide power to the drive gear ring 32, in this utility model, a drive gear 7 is installed at the bottom of the drone 1 shell. The drive gear 7 meshes with the drive gear ring 32. As the drive gear 7 rotates, the drive gear ring 32 rotates synchronously, so as to drive multiple linkage gears 4 and the linkage shaft 5 connected to them to rotate synchronously.

[0028] It is worth mentioning that in this utility model, the drive gear 7, drive gear ring 32 and linkage gear 4 are all located inside the sheath 11, which can effectively avoid contamination by external impurities and ensure the accuracy and safety of the drive gear 7, drive gear ring 32 and linkage gear 4 in the meshing state.

[0029] like Figure 6 As shown, in order to provide power to the drive gear 7, in this invention, a driver 8 is installed at the central shaft position of the drive gear 7 to drive its rotation. The driver 8 is installed inside the shell of the UAV 1. Therefore, when the drive gear 7 rotates, the drive gear ring 32 rotates synchronously.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
