Description

Technical Field

[0001] The present invention belongs to the technical field of UAV transportation, and more specifically, particularly relates to an adjustable hanging device for UAVs. Background Art

[0002] In many fields such as modern logistics, engineering construction, and emergency rescue, UAVs, relying on their flexibility and efficiency, are playing an increasingly important role in the work of lifting and transporting items. Whether it is transporting materials in mountainous areas with complex terrains or carrying small equipment in congested urban environments, UAV hanging devices have demonstrated unique advantages. Current devices generally require the following technologies in practical applications:

[0003] 1. Reliable connection technology: Ensure the stable connection between the hook, the UAV, and the lifted item, preventing the item from falling off during flight. This involves the design of the connection structure and the selection of materials to withstand the weight of the lifted item and various forces during flight;

[0004] 2. Precise control technology: Operators can precisely control the flight attitude of the UAV and the lifting process, including takeoff, hovering, landing, and position adjustment of the lifted item. This relies on advanced remote control equipment and flight control systems;

[0005] 3. Stable structure design: The hanging device itself needs to have sufficient strength and stability to adapt to different flight conditions and lifting tasks, ensuring normal operation in various environments.

[0006] However, there are some prominent problems with existing UAV hanging devices:

[0007] Firstly, common hooks are usually fixed at a single angle. After the lifting operation is completed, it is extremely inconvenient to disassemble and pick up the lifted items such as the storage box body. When it is necessary to unload the goods at the destination, since the hook cannot flexibly adjust the angle and cannot be adjusted to a way that the notch faces both sides, when removing the lifting rope, the rope needs to be first lifted out along the notch opened at the upper end or the lower end before it can be taken. It is necessary to ensure that the rope is in a relatively loose state before the removal operation, resulting in limited application scope and relatively cumbersome operation.

[0008] On the other hand, storage boxes usually lack a buffering function. When the storage box lands at the destination after being lifted, due to the lack of effective buffering measures, the storage box will directly collide with the ground. This may not only damage the items inside the storage box, especially for fragile and vulnerable items such as electronic products and glass products, where the collision may cause their functions to be damaged or broken, but also cause a large impact on the storage box itself and the connecting components. After long-term use, the storage box is likely to be deformed, cracked, and the connecting parts are loosened, affecting the overall service life and safety of the hanging device. Summary of the Invention

[0009] To solve the above technical problems, the present invention provides an adjustable hanging device for an unmanned aerial vehicle to solve the above problems.

[0010] An adjustable hanging device for an unmanned aerial vehicle includes a hoisting unmanned aerial vehicle body. A hoisting base is fixedly connected to the lower end of the hoisting unmanned aerial vehicle body. A hook main body is sleeved on the outer surface of the hoisting base. A round rod rotating shaft is rotatably connected inside the hook main body. A notch hook is sleeved on the outer surface of the round rod rotating shaft. An arc-shaped card slot is formed inside the notch hook. An L-shaped arc surface clamping block is slidably connected inside the hook main body. The L-shaped arc surface clamping block is clamped inside the arc-shaped card slot. An adjusting screw rod is rotatably connected inside the hook main body. The L-shaped arc surface clamping block is threadedly connected to the outer surface of the adjusting screw rod. A limiting pin rod is fixedly connected to the inner surface of the hook main body. An arc-shaped limiting groove is formed inside the notch hook. The limiting pin rod is arranged inside the arc-shaped limiting groove.

[0011] Preferably, a rotating adjusting handle is fixedly connected to the outer surface of the round rod rotating shaft. A group of rubber anti-slip pads are fixedly connected to both sides of the rotating adjusting handle.

[0012] Preferably, a hoisting buckle rope is arranged inside the notch hook. A storage box cover is arranged at the lower end of the hoisting unmanned aerial vehicle body.

[0013] Preferably, a group of hoisting seats are fixedly connected to the upper end of the storage box cover. The hoisting seats are adapted to the notch hook. A hook retaining cover is threadedly connected to the outer surface of the hoisting seat.

[0014] Preferably, a storage box body is rotatably connected inside the storage box cover. A hollow support seat is fixedly connected to the lower end of the storage box body.

[0015] Preferably, a spring is fixedly connected to the outer surface of the hollow support seat. A T-shaped sliding rod is slidably connected to the lower end of the storage box body. The T-shaped sliding rod is slidably connected inside the hollow support seat.

[0016] Preferably, the T-shaped sliding rod is fixedly connected to the outer surface of the spring. A clamping round rod is fixedly connected inside the T-shaped sliding rod.

[0017] Preferably, a rubber buffer base is clamped on the outer surface of the T-shaped sliding rod. An arc-shaped card slot is formed inside the rubber buffer base.

[0018] Preferably, the clamping round rod is clamped inside the arc-shaped card slot. A group of rubber buffer pads are fixedly connected to the lower end of the rubber buffer base.

[0019] Preferably, a set of drone blades are rotatably connected inside the hoisting drone body, and two drone placement bases are fixedly connected to the lower end of the hoisting drone body.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, by providing a notched hook, when it is necessary to disassemble and unload the storage box body after hoisting is completed, the staff holds and rotates the adjusting screw to rotate. The rotating adjusting screw drives the L-shaped arc-shaped clamping block threadedly connected thereto to slide, so that it extends out of the arc-shaped clamping groove. At this time, the notched hook loses its limit. Under the action of the weight and pulling force of the hoisting drone body or the carried item, it rotates to a posture perpendicular to the hoisting drone body, which is convenient for the staff to disassemble and pick up the goods from the storage box body. By rotating the round rod rotating shaft so that it aligns with the triangular pointing mark on the surface of the hook body, this not only facilitates the socket installation, but also the opening angle of the notched hook after adjustment is away from the surface where the hoisting buckle rope can slide out, ensuring the stability and safety of the hoisting work.

[0022] In the present invention, by providing a rubber buffer base, the rubber buffer base and the rubber buffer pad installed at the lower end of the storage box body play a buffering role. When the storage box body is hoisted to a designated place and placed on the ground, the rubber buffer base and the rubber buffer pad contact the ground first, reducing the impact.

[0023] In the present invention, by providing an adjusting handle, the staff holds and rotates the adjusting handle to rotate the round rod rotating shaft. The hand fits the rubber anti-slip pad to increase the friction and prevent slipping. Rotate the round rod rotating shaft so that it aligns with the triangular pointing mark on the surface of the hook body. The rubber anti-slip pad fits the staff's hand, greatly increasing the friction between the hand and the rotating adjusting handle. This enables the staff's hand not to slip easily when rotating the adjusting handle, can apply force more stably, operate more easily and smoothly, reduce the probability of operation errors caused by hand sliding, and improve the convenience of operation.

[0024] In the present invention, by providing a limiting pin rod, when the notched hook rotates, the limiting pin rod in the hook body fits the inner wall of the arc-shaped limiting groove, limiting the maximum rotatable angle and the rotation path of the notched hook, improving the controllability of the device, and achieving the effects of ensuring operation safety and improving operation accuracy.

[0025] In the present invention, by providing a T-shaped sliding rod, when installing the rubber buffer base, first press the surfaces of the two T-shaped sliding rods to make them slide towards the center of the storage box body, squeezing the spring to contract and store energy. After aligning and placing the rubber buffer base at the lower end of the storage box body, release the T-shaped sliding rod. At this time, the spring force pushes the T-shaped sliding rod to slide to both sides, driving the clamping round rod to be clamped in the arc-shaped clamping groove of the rubber buffer base, completing the quick clamping installation. This method facilitates the disassembly and maintenance after the rubber buffer base has been used for a long time, avoiding the inconvenience of having to invert and lift the storage box body as a whole during maintenance because the buffer mechanism is fixed at the lower end of the storage box body.

DETAILED DESCRIPTION OF THE INVENTION

[0035] The implementation manners of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0036] Please refer to Figures 1 - 8, the present invention provides an adjustable hanging device for a drone, which includes a hoisting drone body 11. A hoisting base 12 is fixedly connected to the lower end of the hoisting drone body 11. A hook body 13 is sleeved on the outer surface of the hoisting base 12. A round rod rotating shaft 14 is rotatably connected inside the hook body 13. A notch hook 15 is sleeved on the outer surface of the round rod rotating shaft 14. An arc-shaped card slot 16 is opened inside the notch hook 15. An L-shaped arc surface clamping block 17 is slidably connected inside the hook body 13. The L-shaped arc surface clamping block 17 is clamped inside the arc-shaped card slot 16. An adjusting screw rod 18 is rotatably connected inside the hook body 13. The L-shaped arc surface clamping block 17 is threadedly connected to the outer surface of the adjusting screw rod 18. A limiting pin rod 19 is fixedly connected to the inner surface of the hook body 13. An arc-shaped limiting groove 21 is opened inside the notch hook 15. The limiting pin rod 19 is arranged inside the arc-shaped limiting groove 21. A rotating adjusting handle 22 is fixedly connected to the outer surface of the round rod rotating shaft 14. A group of rubber anti-slip pads 23 are fixedly connected to both sides of the rotating adjusting handle 22. A hoisting buckle rope 24 is arranged inside the notch hook 15. A storage box cover 25 is arranged at the lower end of the hoisting drone body 11. A group of hoisting seats 26 are fixedly connected to the upper end of the storage box cover 25. The hoisting seats 26 are adapted to the notch hooks 15. A hook retaining cover 27 is threadedly connected to the outer surface of the hoisting seat 26. A storage box body 28 is rotatably connected inside the storage box cover 25. The hook body 13 is sleeved and installed on the surfaces of both the hoisting seat 26 and the hoisting base 12. The assembly is completed by arranging the hoisting buckle rope 24 between the two hook bodies 13. The hook retaining cover 27 threadedly connected to the hoisting seat 26 is screwed to block the hook body 13. The hoisting base 12 blocks and limits the hook body 13 in the same way. The storage box cover 25 and the storage box body 28 form an article storage box, and the articles to be hoisted and transported are placed in the storage box. The hoisting buckle rope 24 is sleeved in the card slot opened inside the notch hook 15 by means of a torsion spring buckle. The staff remotely controls the hoisting drone body 11 to take off. The hoisting assembly formed by the hook body 13, the notch hook 15 and the hoisting buckle rope 24 at the lower end of the hoisting drone body 11 hoists and transports the entire storage box body 28. When there is a need for hoisting and transporting in mountainous areas, rivers, areas with relatively congested traffic or when large items (such as air conditioner exteriors, etc.) need to be transported at high altitudes, the hoisting and transporting method is adopted to improve the transportation efficiency. When it is necessary to disassemble the storage box body 28 for unloading after hoisting, the staff holds the surface of the adjusting screw rod 18 and screws it to rotate. The rotation of the adjusting screw rod 18 drives the L-shaped arc surface clamping block 17 threadedly connected to it to slide. The L-shaped arc surface clamping block 17 slides out of the arc-shaped card slot 16. At this time, the notch hook 15 loses its limit. Under the influence of the weight and pulling force of the upper hoisting drone body 11 or the lower transported items, the notch hook 15 is pulled to rotate (the notch hook 15 rotates around the round rod rotating shaft 14), and the notch hook 15 is pulled to rotate to adjust its angular posture.The notched hook 15 rotates to adjust the notch inside it to a posture perpendicular to the hoisting UAV body 11, which is more convenient for the staff to disassemble and pick up goods from the storage box body 28. The limit pin rod 19 installed inside the hook body 13 is arranged in the arc limit groove 21. When the notched hook 15 rotates, the limit pin rod 19 fits against the inner wall surface of the arc limit groove 21, thereby limiting the maximum rotatable angle and the rotation path of the notched hook 15, improving the controllability of the device. When hoisting and installing the storage box body 28, the hoisting buckle rope 24 is sleeved inside the notch of the notched hook 15. After the installation is completed, the staff holds the surface of the rotation adjustment handle 22 and rotates the round rod rotating shaft 14. The hand of the staff is attached to the surface of the rubber anti-slip pad 23 installed on the surface of the rotation adjustment handle 22 to increase the friction force and achieve the purpose of anti-slip. Rotate the round rod rotating shaft 14 to align it with the triangular pointing mark installed on the surface of the hook body 13. At this time, the arc-shaped card slot 16 and the L-shaped arc surface clamping block 17 are perpendicular to each other. By rotating the adjustment screw rod 18 to drive the L-shaped arc surface clamping block 17 to slide and be clamped in the arc-shaped card slot 16, the notched hook 15 with adjustable rotation angle is not only convenient for socket installation, but also its opening angle is further away from the surface where the hoisting buckle rope 24 can slide out after the adjustment is completed, ensuring the stable and safe progress of the hoisting work.,

[0065] Working principle:

[0066] First step, sleeved and installed on the surfaces of the hoisting seat 26 and the hoisting base 12 are the hook bodies 13. Assembly is completed by setting the hoisting buckle rope 24 between the two hook bodies 13. The hoisting seat 26 blocks and limits the hook body 13 by screwing the hook cover 27 thread - connected to it, and the hoisting base 12 limits the hook body 13 in the same way. The storage box cover 25 and the storage box body 28 form an item storage box, and the items to be hoisted and transported are placed into the box. The hoisting buckle rope 24 is sleeved in the card slot inside the notch hook 15 through the torsion spring buckle method. The staff remotely controls the hoisting drone body 11 to take off, and the hoisting assembly formed by the hook body 13, the notch hook 15 and the hoisting buckle rope 24 hoists and transports the entire storage box body 28, which is applicable to mountainous areas, rivers, traffic - congested areas or high - altitude handling scenarios of large items to improve the handling efficiency.

[0067] In the second step, when the storage box body 28 needs to be disassembled and unloaded after the hoisting is completed, the staff holds and rotates the adjusting screw rod 18. The rotation of the adjusting screw rod 18 drives the L-shaped arc surface clamping block 17 threadedly connected thereto to slide, so that it extends out of the arc-shaped clamping groove 16. At this time, the notch hook 15 loses its limit. Under the action of the weight and pulling force of the hoisting unmanned aerial vehicle body 11 or the carried item, it rotates to a posture perpendicular to the hoisting unmanned aerial vehicle body 11, which is convenient for the staff to disassemble and pick up the goods from the storage box body 28. When the notch hook 15 rotates, the limit pin rod 19 in the hook body 13 fits against the inner wall of the arc-shaped limit groove 21, limiting the maximum rotatable angle and rotation path of the notch hook 15, improving the controllability of the device. When performing the hoisting and installation operation on the storage box body 28, first sleeved the hoisting buckle rope 24 inside the notch of the notch hook 15. Then the staff holds and rotates the adjusting handle 22 to rotate the round rod rotating shaft 14. The hand fits against the rubber anti-slip pad 23 to increase the friction and prevent slipping. Rotate the round rod rotating shaft 14 to align it with the triangular pointing mark on the surface of the hook body 13. At this time, the arc-shaped clamping groove 16 is perpendicular to the L-shaped arc surface clamping block 17. Then rotate the adjusting screw rod 18 to drive the L-shaped arc surface clamping block 17 to be clamped in the arc-shaped clamping groove 16. This not only facilitates the sleeved installation, but also ensures that the opening angle of the notch hook 15 is far away from the surface where the hoisting buckle rope 24 can slide out after adjustment, ensuring the stability and safety of the hoisting work.

[0068] In the third step, the rubber buffer base 34 and the rubber buffer pad 36 installed at the lower end of the storage box body 28 play a buffering role. When the storage box body 28 is hoisted to a designated location and placed on the ground, the rubber buffer base 34 and the rubber buffer pad 36 contact the ground first to slow down the impact. When installing the rubber buffer base 34, first press the surfaces of the two T-shaped sliding rods 32 to make them slide toward the center of the storage box body 28, squeezing the spring 31 to contract and store energy. After aligning the rubber buffer base 34 and placing it at the lower end of the storage box body 28, release the T-shaped sliding rods 32. At this time, the elastic force of the spring 31 pushes the T-shaped sliding rods 32 to slide to both sides, driving the clamping round rod 33 to be clamped in the arc-shaped clamping groove 35 of the rubber buffer base 34, completing the quick clamping installation. This method is convenient for disassembling and maintaining the rubber buffer base 34 after long-term use, avoiding the inconvenience of having to invert and lift and move the storage box body 28 as a whole when maintaining because the buffer mechanism is fixed at the lower end of the storage box body 28.
