Description

Technical Field

[0001] This utility model belongs to the field of drone delivery technology, and specifically relates to a drone material delivery buffer landing structure. Background Technology

[0002] A drone is an unmanned aerial vehicle controlled remotely or autonomously. During the critical 72 hours after a disaster, traditional road closures hinder ground rescue efforts. Drones can establish low-altitude logistics networks, delivering critical supplies within 12-24 hours. When drones perform supply delivery missions, the impact during landing or airdrop can damage supplies, cause equipment malfunctions, or even secondary disasters. Buffer design is a crucial element in ensuring mission success.

[0003] Currently, drone-based airdrops of supplies generally employ a rope-suspended delivery system: the supply container is fixed to the underside of the drone via rigid or flexible ropes. Upon reaching the target area, the ropes are released mechanically or electronically, causing the supplies to fall freely. After release, the supplies directly impact the ground, far exceeding their own tolerance limits, resulting in damage to the supplies. Utility Model Content

[0004] To address the problem that when a cargo container is fixed to the underside of a drone with rigid or flexible ropes, and the ropes are released mechanically or electronically upon reaching the target area, causing the cargo to fall directly to the ground and exceed its own tolerance limit, resulting in damage to the cargo, this utility model proposes a drone cargo delivery buffer landing structure to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a buffer landing structure for unmanned aerial vehicle (UAV) material delivery, including a body. A limiting component is provided at the bottom of the body, and an adjusting component is provided at the bottom of the limiting component. A first buffer component and a second buffer component are respectively provided on the outer surface of the adjusting component. The limiting component is used to fix the adjusting component, and the adjusting component is used to adjust the cargo space. The first buffer component is used to protect the material box, and the second buffer component is used to protect the adjusting component and the material box.

[0007] Furthermore, the limiting component includes a small push rod, which is fixedly installed inside the machine body. The movable end of the small push rod is fixedly connected to a side plate, and the outer surface of the side plate is fixedly connected to a plug plate. There are two sets of both the small push rod and the side plate, and the outer surface of each set of the side plate has multiple sets of plug plates.

[0008] Furthermore, the adjustment assembly includes a connecting plate, the plug-in plate is plugged into the connecting plate, a large curved rod is fixedly connected to the outer surface of the connecting plate, an adjustment rod is slidably connected inside the large curved rod, a limit hole is opened on the outer surface of the adjustment rod, a bolt is passed through the large curved rod and the adjustment rod, and a crossbar is fixedly connected to the outer surface of the adjustment rod.

[0009] Furthermore, the first buffer assembly includes a fixed cylinder, which is fixedly connected to the outer surface of the crossbar. A small curved rod is fixedly connected to the outer surface of the fixed cylinder. A first spring is fixedly connected inside the small curved rod. A first damping block is fixedly connected to the upper end of the first spring. A sliding rod is fixedly connected to the top of the first damping block. A load rack is fixedly connected to the upper end of the sliding rod.

[0010] Furthermore, the second buffer assembly includes a connecting seat, a second spring is fixedly connected inside the connecting seat, a second damping block is fixedly connected to the upper end of the second spring, the second damping block is fixedly connected to the lower end of the adjusting rod, the adjusting rod is slidably connected to the connecting seat, and a grounding rod is fixedly connected to the bottom of the connecting seat.

[0011] Furthermore, the large curved rod, adjusting rod, crossbar, small curved rod, sliding rod, load rack, and grounding rod are all hollow structures.

[0012] Furthermore, the grounding rod has a small end diameter and a certain curvature.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by adjusting the connection between the adjustment component and the first buffer component, changes the overall size of the adjustment component, allowing material boxes of different sizes to be placed between the adjustment component and the first buffer component. After the material box is tied and fixed to the first buffer component, when the adjustment component touches the ground, the extension and retraction of the first buffer component provides cushioning and shock absorption, preventing the material box on top of the first buffer component from being subjected to strong impact, thus protecting different material boxes.

[0015] 2. This utility model connects the connecting seat and the grounding rod. When the grounding rod contacts the ground, it causes the connecting seat and the second damping block to slide relative to each other. The friction between the connecting seat and the second damping block and the compression of the second spring can consume part of the impact force and protect the material box. At the same time, the special shape design of the grounding rod makes it heavy in the middle and light at both ends. Even if it has a certain tilt angle when landing, it can adjust its own posture after landing to avoid damage caused by tilting of the material box.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a buffer landing structure for unmanned aerial vehicle (UAV) material delivery, including a body 1. A limiting component 2 is provided at the bottom of the body 1. An adjusting component 3 is provided at the bottom of the limiting component 2. A first buffer component 4 and a second buffer component 5 are respectively provided on the outer surface of the adjusting component 3. The limiting component 2 is used to fix the adjusting component 3. The adjusting component 3 is used to adjust the cargo space. The first buffer component 4 is used to protect the material box. The second buffer component 5 is used to protect the adjusting component 3 and the material box.

[0029] After the aircraft 1 is connected to the adjustment component 3 via the limiting component 2, the supply box is placed between the first buffer component 4 and the adjustment component 3, and the supply box is tied and fixed to the first buffer component 4 with ropes. After the aircraft 1 carries the supply box to the designated area, the limiting component 2 is activated to separate it from the adjustment component 3, realizing the airdrop of the supply box. When it falls to the ground, the first buffer component 4 and the second buffer component 5 are used to cushion and protect the supply box, and the second buffer component 5 is used to adjust the attitude to prevent the supply box from tipping over.

[0030] This utility model adjusts the connection between the adjusting component 3 and the first buffer component 4, thereby changing the overall size of the adjusting component 3. Different sized material boxes can be placed between the adjusting component 3 and the first buffer component 4. After the material box is tied and fixed to the first buffer component 4, when the adjusting component 3 touches the ground, the first buffer component 4 expands and contracts to absorb shock, preventing the material box on top of the first buffer component 4 from being subjected to strong impact, thus protecting different material boxes.

[0031] In one embodiment, the limiting component 2 includes a small push rod 201, which is fixedly installed inside the body 1. The movable end of the small push rod 201 is fixedly connected to a side plate 202, and the outer surface of the side plate 202 is fixedly connected to a plug plate 203. There are two sets of both the small push rod 201 and the side plate 202, and each set of the outer surface of the side plate 202 has multiple sets of plug plates 203.

[0032] In one embodiment, the adjustment component 3 includes a connecting plate 301, a plug-in plate 203 is plugged into the connecting plate 301, a large curved rod 302 is fixedly connected to the outer surface of the connecting plate 301, an adjustment rod 303 is slidably connected inside the large curved rod 302, a limit hole 304 is formed on the outer surface of the adjustment rod 303, a bolt 305 passes through the large curved rod 302 and the adjustment rod 303, and a crossbar 306 is fixedly connected to the outer surface of the adjustment rod 303.

[0033] The small push rod 201 inside the fuselage 1 is activated. When the movable end of the small push rod 201 retracts, it moves the side plate 202. The plug-in plate 203 on the outer surface of the side plate 202 plugs into the connecting plate 301, thus connecting and fixing the connecting plate 301 to the fuselage 1. After the fuselage 1 flies to the designated area with the connecting plate 301, the small push rod 201 is activated again to push the side plate 202 and the plug-in plate 203 to move, causing the plug-in plate 203 to separate from the connecting plate 301, allowing the connecting plate 301 to be airdropped to the designated area.

[0034] In one embodiment, the first buffer assembly 4 includes a fixed cylinder 401, which is fixedly connected to the outer surface of the crossbar 306. A small curved rod 402 is fixedly connected to the outer surface of the fixed cylinder 401. A first spring 403 is fixedly connected inside the small curved rod 402. A first damping block 404 is fixedly connected to the upper end of the first spring 403. A sliding rod 405 is fixedly connected to the top of the first damping block 404. A load rack 406 is fixedly connected to the upper end of the sliding rod 405.

[0035] Rotating bolt 305 separates it from the limiting hole 304 on the outer surface of adjusting rod 303, releasing the limiting fixation between adjusting rod 303 and large curved rod 302. Pulling crossbar 306 causes adjusting rod 303 to slide. Crossbar 306 drives the rack 406 to slide synchronously through small curved rod 402 and sliding rod 405, changing the distance between rack 406 and connecting plate 301, allowing material boxes of different heights to be fixed on top of rack 406. When airdropping material boxes, adjusting rod 303 transmits the impact to small curved rod 402. The first damping block 404 inside small curved rod 402, sliding rod 405, and material boxes on top of rack 406 continue to move downward under gravity. The impact force is dissipated by friction between the first damping block 404 and small curved rod 402 and by compressing the first spring 403, thus protecting the material boxes on top of rack 406.

[0036] In one embodiment, the second buffer assembly 5 includes a connecting seat 501, a second spring 502 is fixedly connected inside the connecting seat 501, a second damping block 503 is fixedly connected to the upper end of the second spring 502, the second damping block 503 is fixedly connected to the lower end of the adjusting rod 303, the adjusting rod 303 is slidably connected to the connecting seat 501, and a grounding rod 504 is fixedly connected to the bottom of the connecting seat 501.

[0037] When the supply box is airdropped, the grounding rod 504 at the lower end of the adjusting rod 303 contacts the ground. The grounding rod 504 causes the connecting seat 501 and the second damping block 503 to slide relative to each other. The impact force is consumed by the friction between the connecting seat 501 and the second damping block 503 and the compression of the second spring 502. This can buffer and protect the adjusting rod 303, the rack 406 and the supply box.

[0038] In one embodiment, for the aforementioned large curved rod 302, the large curved rod 302, the adjusting rod 303, the crossbar 306, the small curved rod 402, the sliding rod 405, the load rack 406, and the grounding rod 504 are all hollow structures.

[0039] The above structure, while ensuring strength, adopts a hollow structure to reduce the overall weight, allowing the aircraft 1 to carry more supplies and extend its flight range.

[0040] In one embodiment, the grounding rod 504 has a small end diameter and a certain curvature.

[0041] The special shape design of the grounding rod 504 allows its center of gravity to be located in the middle. Even if the grounding rod 504 has a certain tilt angle when it touches the ground, its special shape can correct its posture and prevent the items in the material box from being damaged due to tilting after landing.

[0042] Through the above technical solutions: 1. By adjusting the connection between the adjustment component 3 and the first buffer component 4, the overall size of the adjustment component 3 can be changed, allowing material boxes of different sizes to be placed between the adjustment component 3 and the first buffer component 4. After the material boxes are tied and fixed to the first buffer component 4, when the adjustment component 3 touches the ground, the extension and retraction of the first buffer component 4 will buffer and absorb shock, preventing the material boxes on top of the first buffer component 4 from being subjected to strong impact, thus protecting different material boxes; 2. Through the connection between the connecting seat 501 and the grounding rod 504, when the grounding rod 504 contacts the ground, it will cause the connecting seat 501 and the second damping block 503 to slide relative to each other. The friction between the connecting seat 501 and the second damping block 503 and the compression of the second spring 502 can consume part of the impact force, thus protecting the material boxes. At the same time, the special shape design of the grounding rod 504 makes it heavy in the middle and light at both ends. Even if it has a certain tilt angle when landing, it can adjust its own posture after landing, avoiding damage to the material boxes caused by tilting.
