Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically a modular and reconfigurable UAV emergency payload rapid mounting device. Background Technology

[0002] Drones have a wide range of applications, including logistics and rescue. They can be equipped with mounting devices for transporting goods in logistics. In the emergency rescue industry, aerial dropping is a frequent occurrence. As the connecting mechanism between the aircraft and the dropped object, the mounting mechanism plays a very important role. Normally, aircraft are used as independent units. However, in response to rescue situations, each aircraft executes different flight commands. Therefore, different equipment needs to be mounted on the aircraft to achieve functions that the aircraft did not originally have.

[0003] In the existing technology, a novel UAV payload mounting device with announcement number CN215663972U is proposed. This application connects two horizontal rods and two vertical rods into a "well"-shaped bracket structure through a cross buckle, and then fixes it to the UAV's landing gear through landing gear connectors at both ends of the vertical rods. However, in use, the mounting device is usually installed directly by installing the components, which does not allow for multi-directional adjustment of the position of the first limiting ring. This makes the device unable to adapt to the differences in landing gear mounting positions of different UAV models, limiting the rapid deployment capability of emergency payloads. When switching missions, the entire mounting component needs to be replaced, which significantly reduces the mission response speed of UAVs and the equipment reuse rate. To address this, we provide a modular and reconfigurable rapid mounting device for UAV emergency payloads. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, solve the problems of multi-directional adjustment of the first limiting ring position and one-click quick assembly and disassembly of emergency payloads, enabling rapid switching between logistics and rescue scenarios, a modular and reconfigurable UAV emergency payload rapid mounting device is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A modular, reconfigurable, rapid payload mounting system for unmanned aerial vehicles (UAVs) includes: The mounting plate has a square groove in the middle of its upper end, and a first circular groove in the inner side wall of the square groove. The mounting plate is connected to mounting brackets on both sides by bolts, and the upper end of the mounting brackets has a travel groove. A load removal assembly is disposed on both sides of the upper end of the mounting plate and is used to remove the load.

[0006] Preferably, the load removal assembly includes: Square holes are formed on both sides of the upper end of the mounting plate. A fixing plate is fixedly installed on the inner side wall of the square holes. A second circular groove is formed inside the fixing plate, and a movable rod is set inside the second circular groove.

[0007] Preferably, the surface of the movable rod is provided with a fixed plate and a return spring, the other end of the return spring is fixedly connected to the fixed plate, and one end of the return spring is provided on the surface of the fixed plate.

[0008] Preferably, a pull plate is fixedly installed on the upper end of the fixed plate, the surface of the pull plate is provided with an anti-slip pad, and the other end of the movable rod is provided with a plug, the surface of the plug being connected to a load through a slot.

[0009] Preferred options also include: A connection position adjustment component is installed on one side of the mounting bracket and is used to adjust the connection position.

[0010] Preferably, the connection position adjustment component includes: A protective shell is bolted to one side of the mounting bracket. The protective shell has a circular hole on its front side. A transmission rod is installed inside the circular hole. A turntable is fixedly installed at one end of the transmission rod, and a worm gear is fixedly installed at the other end of the transmission rod. A worm wheel meshes with the surface of the worm gear. A rotating rod is connected to the other side of the worm wheel. A double-acting screw is fixedly installed at one end of the rotating rod, and one end of the double-acting screw is set in a stroke groove through a bearing.

[0011] Preferably, the surface of the bidirectional lead screw is threadedly connected to a threaded block through a first threaded hole. The threaded block is partially adapted to the stroke groove. A movable plate is fixedly installed on the upper end of the threaded block. A T-shaped slide groove is formed in the middle of the upper end of the movable plate. Second threaded holes are formed on both sides of the upper end of the movable plate. A first fixing bolt is threadedly connected to the inside of the second threaded hole. A T-shaped slider is threadedly connected to the surface of the first fixing bolt through a third threaded hole, and the T-shaped slider is slidably adapted to the T-shaped slide groove.

[0012] Preferably, a first limiting ring is fixedly installed at the upper end of the T-shaped slider, a first limiting hole is provided at the upper end of the first limiting ring, a second limiting ring is provided at the upper end of the first limiting ring, a second limiting hole is provided at the upper end of the second limiting ring, a second fixing bolt is inserted into the interior of the second limiting hole and the first limiting hole, and a nut is threaded onto the surface of the second fixing bolt.

[0013] The beneficial effects of this utility model are: The connection position adjustment component of this utility model uses a turntable to drive a bidirectional lead screw to rotate, which in turn moves a threaded block and a moving plate to initially adjust the position of the first limiting ring. By rotating the first fixing bolt, a person pushes a T-shaped slider to move within a T-shaped groove for a second adjustment of the first limiting ring's position. When the first limiting ring is properly adjusted, a second limiting ring is placed on top of the first limiting ring, aligning the first and second limiting holes. Finally, the second fixing bolt is inserted through both the first and second limiting holes, and the nut is rotated to clamp the landing gear. This multi-directional adjustment of the first limiting ring's position enables precise three-dimensional positioning of the mounting device, ensuring that the installation plane of the emergency payload always maintains optimal alignment with the UAV's center of gravity, thus improving the device's versatility.

[0014] The load removal component of this utility model allows for one-click quick assembly and disassembly of emergency loads. By pulling a pull plate, a fixed plate is moved, which in turn moves a movable rod. The movable rod then moves the plug out of the slot, releasing the load restriction. Conversely, a return spring causes the plug to be inserted into the slot, restricting the load. This enables one-click quick assembly and disassembly of emergency loads, facilitating rapid switching between logistics and rescue scenarios. Attached Figure Description

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Example 1: Please see Figures 1 to 5 This utility model provides a modular and reconfigurable rapid payload mounting device for unmanned aerial vehicles (UAVs), comprising: Mounting plate 1, with a square groove 2 in the middle of the upper end of mounting plate 1, and a first circular groove 3 in the inner side wall of square groove 2. Mounting brackets 4 are bolted to both sides of mounting plate 1, with a stroke groove in the upper end of mounting bracket 4. Load removal components 5 are set on both sides of the upper end of mounting plate 1 for removing loads. Connection position adjustment components 6 are installed on one side of mounting bracket 4 for adjusting connection position.

[0020] In this embodiment, the position of the first limiting ring 612 is first adjusted in multiple directions by connecting the position adjustment component 6, which realizes the three-dimensional precise positioning of the mounting device installation position, so that the installation plane of the emergency payload always maintains the best matching state with the center of gravity of the UAV; then, the emergency payload can be quickly disassembled and assembled with one click by the payload disassembly component 5, which enables rapid switching between logistics and rescue scenarios.

[0021] Example 2: Based on Embodiment 1, a load removal assembly 5 is further disclosed.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the load removal assembly 5 includes: Square holes 501 are formed on both sides of the upper end of the mounting plate 1. A fixing plate 502 is fixedly installed on the inner side wall of the square holes 501. A second circular groove 503 is formed inside the fixing plate 502. A movable rod 504 is arranged inside the second circular groove 503. A fixing plate 505 and a return spring 506 are arranged on the surface of the movable rod 504. The other end of the return spring 506 is fixedly connected to the fixing plate 505. One end of the return spring 506 is arranged on the surface of the fixing plate 502. A pull plate 507 is fixedly installed on the upper end of the fixing plate 505. An anti-slip pad is arranged on the surface of the pull plate 507. A plug 508 is arranged on the other end of the movable rod 504. A load is connected to the surface of the plug 508 through a slot.

[0023] In this embodiment, when a person pulls the pull plate 507, the fixed plate 505 moves, which in turn moves the movable rod 504. The movable rod 504 then moves the plug 508 out of the slot, releasing the load restriction. Conversely, the return spring 506 causes the plug 508 to be inserted into the slot, restricting the load. This achieves one-click quick assembly and disassembly of the emergency load, enabling rapid switching between logistics and rescue scenarios.

[0024] Example 3: Based on Embodiment 1, a connection position adjustment component 6 is further disclosed.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the connection position adjustment component 6 includes: A protective shell 601 is bolted to one side of the mounting bracket 4. A circular hole is formed on the front of the protective shell 601, and a transmission rod 602 is installed inside the hole. A turntable 603 is fixedly installed at one end of the transmission rod 602, and a worm gear 604 is fixedly installed at the other end. A worm wheel 605 meshes with the surface of the worm gear 604. A rotating rod 606 is connected to the other side of the worm wheel 605. A double-acting lead screw 607 is fixedly installed at one end of the rotating rod 606, and one end of the double-acting lead screw 607 is positioned in a stroke groove via a bearing. A threaded block 608 is threadedly connected to the surface of the double-acting lead screw 607 through a first threaded hole. The threaded block 608 partially fits into the stroke groove. A movable plate 609 is fixedly installed at the upper end of the threaded block 608. A T-shaped groove 610 is provided in the middle. Second threaded holes are provided on both sides of the upper end of the movable plate 609. A first fixing bolt 616 is threadedly connected inside the second threaded hole. A T-shaped slider 611 is threadedly connected to the surface of the first fixing bolt 616 through a third threaded hole. The T-shaped slider 611 slides and adapts to the T-shaped groove 610. A first limiting ring 612 is fixedly installed at the upper end of the T-shaped slider 611. A first limiting hole is provided at the upper end of the first limiting ring 612. A second limiting ring 613 is provided at the upper end of the first limiting ring 612. A second limiting hole is provided at the upper end of the second limiting ring 613. A second fixing bolt 614 is inserted into the second limiting hole and the first limiting hole. A nut 615 is threadedly connected to the surface of the second fixing bolt 614.

[0026] In this embodiment, the turntable 603 drives the transmission rod 602 and the worm gear 604 to rotate synchronously. The worm gear 604 then drives the worm wheel 605 and the rotating rod 606 to rotate synchronously. The rotating rod 606 drives the bidirectional lead screw 607 to rotate, which in turn drives the threaded block 608 and the moving plate 609 to move, initially adjusting the position of the first limiting ring 612. The restriction on the T-shaped slider 611 is released by rotating the first fixing bolt 616, allowing personnel to push the T-shaped slider 611 to move within the T-shaped groove 610. The position of the first limiting ring 612 is then adjusted a second time. When the first... When the position of the first limiting ring 612 is properly adjusted, the first limiting ring 612 is set on the landing gear of the UAV. Then, the second limiting ring 613 is placed on the first limiting ring 612, so that the first limiting hole and the second limiting hole correspond to each other. Finally, the second fixing bolt 614 is passed through the first limiting hole and the second limiting hole, and the rotating nut 615 clamps the landing gear. This achieves the function of adjusting the position of the first limiting ring 612 in multiple directions, realizing the three-dimensional precise positioning of the mounting device installation position, so that the installation plane of the emergency load is always in the best matching state with the center of gravity of the UAV, and improving the versatility of the device.
