Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) transportation, and particularly to a UAV suspension transportation system and a control method therefor. Background Art

[0002] With the continuous progress of UAV technology and the expansion of application scenarios, transport UAVs will demonstrate their unique advantages and values in more fields. In the future, transport UAVs may develop in the directions of greater payload, longer flight range, higher intelligence, etc. to meet the needs of cargo transportation in different fields. When a UAV transports goods, a suspension structure needs to be installed to facilitate the connection of different goods.

[0003] For example, the publication number is CN118494758A. This invention relates to the technical field of UAV equipment and particularly to a transport UAV. The transport UAV includes a UAV main body and a suspension structure. The suspension structure includes a mounting plate, a first connection structure, and a transmission component. The first connection structure is movably connected to the transmission component. The mounting plate is provided at the bottom of the UAV main body, and the first connection structure is slidably connected to one end of the mounting plate away from the UAV main body. This invention loads goods onto the UAV by means of the first connection structure being clamped to a sling. Different slings can be quickly switched for different specifications of goods, which is convenient and fast. When the flight state of the transport UAV is affected, the first connection structure can be separated from the sling to ensure the safety of the transport UAV and avoid greater losses.

[0004] In the above prior art, the staff fixes a sling through a clamping structure at the bottom of the UAV, thereby facilitating the switching of slings. When transporting goods, the goods are fixed by the sling and the UAV transports them. However, when the UAV transports goods at a relatively high speed, wind will be generated. When the goods have a large shape, their windward area will also be large. Therefore, a large wind resistance will be generated, which will affect the transportation of the UAV and increase the power consumption of the UAV. Moreover, when the goods are affected by wind resistance, they will swing, which will also affect the flight of the UAV. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art that when the UAV transports goods at a relatively high speed, wind will be generated. When the goods have a large shape, their windward area will also be large. Therefore, a large wind resistance will be generated, which will affect the transportation of the UAV and increase the power consumption of the UAV. Moreover, when the goods are affected by wind resistance, they will swing, which will also affect the flight of the UAV.

[0008] As a preferred implementation manner, a telescopic plate is slidably connected inside the wind guiding plate, second chutes are provided in the middle of both sides of the wind guiding plate, card slots are arranged at equal intervals on both sides of the wind guiding plate located in the second chutes, clamping members are provided on both sides of the top of the telescopic plate, and the telescopic plate moves downward to drive the fixing rod to slide along the track of the second chute, thereby adjusting the position of the telescopic plate.

[0009] As a preferred embodiment, the clamping member includes a fixing rod, which is fixedly connected to the telescopic plate and slidably connected to the second chute. A first spring is rotatably connected inside the fixing rod. One end of the first spring away from the telescopic plate is fixedly connected to a pull rod. The pull rod slidably penetrates through the fixing rod. One end of the pull rod outside the fixing rod is fixedly connected to a first pull plate. First clamping rods are fixedly connected to both sides of the first pull plate. The first clamping rods are clamped with the clamping grooves. Pull the first pull plate according to the height of the goods. The first pull plate drives the first clamping rods to separate from the air deflector and deflects the first pull plate. At this time, the first clamping rods lose fixation. Pull the telescopic plate downward. The telescopic plate extends out of the air deflector, and its height is equal to that of the goods. Then pull the first pull plate again and reverse it. After aligning the clamping position of the first clamping rods with the air deflector, release it, so that the first spring pulls the first pull plate to drive the first clamping rods to be clamped and fixed to the air deflector again.

[0010] As a preferred embodiment, the limiting and protecting assembly includes a fixing box, which is fixedly arranged at one side of the air deflector at equal intervals. A winding rod is rotatably connected inside the fixing box. A limiting rope is wound and connected to the middle of the winding rod. One end of the limiting rope penetrates through the fixing box and is slidably connected to the fixing box. One end of the limiting rope outside the fixing box is fixedly connected to a first lock. Pull and rotate the turntable according to the position of the goods. The turntable drives the second clamping rods to separate from the air deflector. The rotation of the turntable drives the winding rod to rotate. The winding rods are connected to each other through a universal shaft. Therefore, several winding rods rotate synchronously. The rotation of the winding rod pays out the limiting rope. At this time, the first lock approaches the goods and buckles with the goods. Then reverse the turntable to make the winding rod in a taut state.

[0011] As a preferred embodiment, a universal shaft is arranged between each winding rod. One end of a winding rod on one side penetrates through the fixing box. A first connecting sleeve rod is slidably connected to the end of the winding rod outside the fixing box. A turntable is fixedly connected to the end of the first connecting sleeve rod away from the fixing box. Second clamping rods are fixedly arranged in an annular array on the outer ring of the turntable close to the fixing box. The second clamping rods are clamped with the air deflector. Push the turntable to make the second clamping rods clamp tightly in the air deflector to limit the turntable. When the goods are transported and are blown by the wind, the first lock can pull and limit the goods, so as to avoid large swings causing the aircraft to fly and shake. When the position of the air deflector is adjusted, the fixing box drives the goods to rotate through the first lock, so as to provide real-time protection.

The goods are placed at the bottom end of the hanging plate and connected to the goods through the second buckle to achieve hanging.

[0013] As a preferred embodiment, a second pulling plate is slidably connected to the middle of the suspension rope, a middle part of the top end of the second pulling plate is fixedly connected with a protective connecting sleeve rod, the protective connecting sleeve rod is slidably connected to the outer wall of the suspension rope, and the top end of the protective connecting sleeve rod slidably penetrates through the first slider and is located on both sides of the suspension rope. Move the first slider according to the size of the goods. When moving, pull the second pulling plate downward. The second pulling plate drives the third clamping rod and the protective connecting sleeve rod to move downward. The third clamping rod is separated from the hanging plate. The protective connecting sleeve rod slides at the bottom end of the first slider and pulls the second spring. At this time, move the second pulling plate, and the second pulling plate drives the suspension rope and the first slider to slide along the track of the third chute, so as to adjust the position of the first slider.

[0014] As a preferred embodiment, a second spring is fixedly connected to one end of the protective connecting sleeve rod located inside the first slider, the second spring is fixedly connected with the first slider, third clamping rods are fixedly connected to both sides of the second pulling plate located on the protective connecting sleeve rod, and the third clamping rods are clamped on both sides of the hanging plate located in the third chute. When adjusted to a suitable position, release the second pulling plate, and the second spring rebounds to drive the protective connecting sleeve rod to rise. The protective connecting sleeve rod drives the third clamping rod to be clamped with both sides of the hanging plate located in the third chute, so as to fix the first slider, and thus it is convenient to connect different goods.

[0015] A control method for an unmanned aerial vehicle hanging and carrying system includes the following steps:

[0016] S1. First, place the goods at the bottom end of the hanging plate. Move the first slider according to the size of the goods. When moving, pull the second pulling plate downward. The second pulling plate drives the third clamping rod and the protective connecting sleeve rod to move downward. The third clamping rod is separated from the hanging plate. The protective connecting sleeve rod slides at the bottom end of the first slider and pulls the second spring. At this time, move the second pulling plate, and the second pulling plate drives the suspension rope and the first slider to slide along the track of the third chute to adjust the position of the first slider. When adjusted to a suitable position, release the second pulling plate, and the second spring rebounds to drive the protective connecting sleeve rod to rise. The protective connecting sleeve rod drives the third clamping rod to be clamped with both sides of the hanging plate located in the third chute, so as to fix the first slider;

[0017] S2. Next, pull and rotate the turntable according to the position of the goods. The turntable drives the second clamping rod to separate from the air deflector. The rotation of the turntable drives the winding rod to rotate. The winding rods are interconnected by a universal shaft. Therefore, several winding rods rotate synchronously. The rotation of the winding rod pays out the limiting rope. At this time, the first lock catches up with the goods and latches onto the goods. Then, reverse the turntable to make the winding rod in a taut state. Then, push the turntable to make the second clamping rod snap into the air deflector to limit the turntable.

[0018] S3. Pull the first pull plate according to the height of the goods. The first pull plate drives the first clamping rod to separate from the air deflector and deflect the first pull plate. At this time, the first clamping rod loses its fixation. Pull down the telescopic plate. The telescopic plate extends out of the air deflector. Its height is equal to that of the goods. Then, pull the first pull plate again and reverse it. After aligning the clamping position of the first clamping rod with the air deflector, release it. The first spring pulls the first pull plate to drive the first clamping rod to be clamped and fixed to the air deflector again.

[0019] S4. When transporting the goods, start the motor. The motor drives the rotating shaft to rotate. The rotating shaft drives the gear to rotate. The gear drives the toothed ring to rotate. The toothed ring drives the support slider to rotate. The support slider drives the air deflector to move along the track of the first chute, so that the convex surface of the air deflector faces the moving direction. The wind generated by the movement blows to both sides along the inclined surface of the air deflector. And when there is a crosswind during transportation, the position of the air deflector can be adjusted to face the crosswind. Among them, the first lock can limit the pulling of the goods. When the position of the air deflector is adjusted, the fixed box drives the goods to rotate through the first lock.

[0020] The beneficial effects of the present invention are as follows:

[0021] In the present invention, when the body is transporting, start the motor. The motor drives the rotating shaft to rotate. The rotating shaft drives the gear to rotate. The gear drives the toothed ring to rotate. The toothed ring drives the support slider to rotate. The support slider drives the air deflector to move along the track of the first chute, so that the convex surface of the air deflector faces the moving direction. The wind generated by the movement blows to both sides along the inclined surface of the air deflector. Thus, when the goods move, the windward area is large, resulting in a large wind resistance, reducing power consumption and the stability of goods transportation. And when there is a crosswind during transportation, the position of the air deflector can be adjusted to face the crosswind, reducing the resistance generated by the crosswind.

[0022] In the present invention, the turntable is pulled and rotated according to the position of the goods. The turntable drives the second clamping rod to separate from the air deflector. The rotation of the turntable drives the winding rod to rotate. The winding rods are interconnected by universal shafts. Therefore, several winding rods rotate synchronously. The rotation of the winding rod pays out the limiting rope. At this time, the first lock approaches the goods and latches with the goods. Then, the turntable is reversed to make the winding rod in a taut state. Then, the turntable is pushed to make the second clamping rod clamp tightly in the air deflector to limit the turntable. When the goods are being transported and are blown by the wind, the first lock can pull and limit the goods, thus avoiding large swings that cause the body of the aircraft to fly and shake. When the position of the air deflector is adjusted, the fixed box drives the goods to rotate through the first lock, so as to provide real-time protection.

[0023] In the present invention, the goods are placed at the bottom of the hanging plate. The first slider is moved according to the size of the goods. When moving, the second pull plate is pulled downward. The second pull plate drives the third clamping rod and the protective connecting sleeve rod to move downward. The third clamping rod separates from the hanging plate. The protective connecting sleeve rod slides at the bottom of the first slider and pulls the second spring. At this time, the second pull plate is moved. The second pull plate drives the suspension rope and the first slider to slide along the track of the third chute, so as to adjust the position of the first slider. After adjusting to the appropriate position, the second pull plate is released. The second spring rebounds to drive the protective connecting sleeve rod to rise. The protective connecting sleeve rod drives the third clamping rod to be clamped on both sides of the third chute of the hanging plate, so as to fix the first slider. Therefore, it is convenient to connect different goods. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 - Figure 9 , the present invention provides a technical solution: an unmanned aerial vehicle hanging transportation system, including an airframe 1, a wing 11 is arranged at the top end of the airframe 1, support frames 12 are fixedly connected to both sides of the bottom end of the airframe 1, a hanging structure is arranged in the middle of the bottom end of the airframe 1, the hanging structure includes a suspension main body 21, a first chute 211 is opened on the outer side of the bottom end of the suspension main body 21, an air deflector assembly is arranged on one side of the suspension main body 21 located in the first chute 211, the air deflector assembly includes an air deflector 22, a limit protection assembly is arranged on one side of the air deflector 22, and a hanging assembly is arranged in the middle of the bottom end of the suspension main body 21.

[0037] As Figure 1 - Figure 9As shown, a support slider 221 is fixedly connected to the middle of the top end of the air deflector 22. The support slider 221 is slidably connected inside the first chute 211. A toothed ring 222 is fixedly connected to one side of the top end of the support slider 221. The toothed ring 222 is rotatably connected to the suspension main body 21. A gear 223 is meshed with one side of the toothed ring 222 close to the support slider 221. A rotating shaft 224 is fixedly connected to the top end of the gear 223. The rotating shaft 224 penetrates through the suspension main body 21 and is rotatably connected to the suspension main body 21. The top end of the rotating shaft 224 is drivingly connected to a motor 225. The motor 225 is fixedly connected to the suspension main body 21. A telescopic plate 228 is slidably connected inside the air deflector 22. Second chutes 226 are provided in the middle of both sides of the air deflector 22. Card slots 227 are arranged at equal intervals on both sides of the air deflector 22 where the second chutes 226 are located.

[0038] In this embodiment, when the machine body 1 is in transportation, the motor 225 is started. The motor 225 drives the rotating shaft 224 to rotate. The rotating shaft 224 drives the gear 223 to rotate. The gear 223 drives the toothed ring 222 to rotate. The toothed ring 222 drives the support slider 221 to rotate. The support slider 221 drives the air deflector 22 to move along the track of the first chute 211, so that the convex surface of the air deflector 22 faces the moving direction, and the wind generated by the movement blows to both sides along the inclined surface of the air deflector 22. Thus, when the goods are moving, the windward area is large, resulting in a large wind resistance, reducing power consumption and the stability of goods transportation. And when there is a crosswind during transportation, the position of the air deflector 22 can be adjusted to face the crosswind, reducing the resistance generated by the crosswind.

[0039] As Figure 1 - Figure 9 As shown, clamping members are arranged on both sides of the top end of the telescopic plate 228. The clamping members include fixing rods 2294. The fixing rods 2294 are fixedly connected to the telescopic plate 228 and are slidably connected to the second chutes 226. A first spring 2293 is rotatably connected inside the fixing rods 2294. One end of the first spring 2293 away from the telescopic plate 228 is fixedly connected to a pull rod 2292. The pull rod 2292 slidably penetrates through the fixing rod 2294. A first pull plate 229 is fixedly connected to the end of the pull rod 2292 outside the fixing rod 2294. First clamping rods 2291 are fixedly connected to both sides of the first pull plate 229. The first clamping rods 2291 are clamped with the card slots 227.

[0040] In this embodiment, the first pull plate 229 is pulled according to the height of the goods. The first pull plate 229 drives the first clamping rod 2291 to separate from the air deflector 22, and the first pull plate 229 is deflected. At this time, the first clamping rod 2291 loses its fixation, and the telescopic plate 228 is pulled downward. The telescopic plate 228 extends out of the air deflector 22, and its height is equal to that of the goods. Then, the first pull plate 229 is pulled again and reversed. After the clamping position of the first clamping rod 2291 is aligned with the air deflector 22, it is released, so that the first spring 2293 pulls the first pull plate 229 to drive the first clamping rod 2291 to be clamped and fixed with the air deflector 22 again. Therefore, it is convenient to adapt to goods of different specifications.

[0041] As Figure 1 - Figure 9 As shown in the figure, the limit protection component includes a fixed box 23. The fixed boxes 23 are arranged equidistantly and fixed on one side of the air deflector 22. A winding rod 231 is rotatably connected inside the fixed box 23. A limit rope 232 is wound and connected in the middle of the winding rod 231. One end of the limit rope 232 passes through the fixed box 23 and is slidably connected with the fixed box 23. One end of the limit rope 232 outside the fixed box 23 is fixedly connected with a first buckle 233. A universal shaft 234 is arranged between each winding rod 231. One end of one side winding rod 231 passes through the fixed box 23. One end of the winding rod 231 outside the fixed box 23 is slidably connected with a first connecting sleeve rod 235. One end of the first connecting sleeve rod 235 away from the fixed box 23 is fixedly connected with a turntable 236. A second clamping rod 237 is fixedly connected in an annular array on the outer ring of the side of the turntable 236 close to the fixed box 23. The second clamping rod 237 is clamped with the air deflector 22.

[0042] In this embodiment, the turntable 236 is pulled and rotated according to the position of the goods. The turntable 236 drives the second clamping rod 237 to separate from the air deflector 22. The rotation of the turntable 236 drives the winding rod 231 to rotate. The winding rods 231 are connected to each other through the universal shaft 234. Therefore, several winding rods 231 rotate synchronously. The rotation of the winding rod 231 pays out the limit rope 232. At this time, the first buckle 233 approaches the goods and buckles with the goods. Then, the turntable 236 is reversed, so that the winding rod 231 is in a tight state. Then, the turntable 236 is pushed, so that the second clamping rod 237 is clamped in the air deflector 22 to limit the turntable 236. When the goods are carried and blown by the wind, the first buckle 233 can pull and limit the goods, so as to avoid large swings causing the flight of the body 1 to shake. When the position of the air deflector 22 is adjusted, the fixed box 23 drives the goods to rotate through the first buckle 233, so as to provide real-time protection.

[0043] As Figure 1 - Figure 9As shown in the figure, the hanging component includes a hanging plate 24. The hanging plate 24 is rotatably connected to the middle of the bottom end of the suspension main body 21. A third chute 241 is formed in an annular array at the bottom end of the hanging plate 24. A first slider 242 is slidably connected inside the third chute 241. A middle part of the bottom end of the first slider 242 is fixedly connected to a suspension rope 243. A bottom end of the suspension rope 243 is fixedly connected to a second buckle 244. A second pull plate 248 is slidably connected to the middle of the suspension rope 243. A middle part of the top end of the second pull plate 248 is fixedly connected to a protective connecting sleeve rod 245. The protective connecting sleeve rod 245 is slidably connected to the outer wall of the suspension rope 243. The top end of the protective connecting sleeve rod 245 slidably penetrates through the first slider 242 and is located on both sides of the suspension rope 243. One end of the protective connecting sleeve rod 245 located inside the first slider 242 is fixedly connected to a second spring 246. The second spring 246 is fixedly connected to the first slider 242. The second pull plate 248 is fixedly connected with third clamping rods 247 on both sides of the protective connecting sleeve rod 245. The third clamping rods 247 are clamped on both sides of the hanging plate 24 where the third chute 241 is located.

[0044] In this embodiment, the goods are placed at the bottom end of the hanging plate 24. The first slider 242 is moved according to the size of the goods. When moving, the second pull plate 248 is pulled downward. The second pull plate 248 drives the third clamping rod 247 and the protective connecting sleeve rod 245 to move downward. The third clamping rod 247 is separated from the hanging plate 24. The protective connecting sleeve rod 245 slides at the bottom end of the first slider 242 and pulls the second spring 246. At this time, the second pull plate 248 is moved. The second pull plate 248 drives the suspension rope 243 and the first slider 242 to slide along the track of the third chute 241, so as to adjust the position of the first slider 242. When the adjustment reaches the appropriate position, the second pull plate 248 is released. The second spring 246 rebounds and drives the protective connecting sleeve rod 245 to rise. The protective connecting sleeve rod 245 drives the third clamping rod 247 to be clamped with the hanging plate 24 on both sides of the third chute 241, so as to fix the first slider 242. Therefore, it is convenient to connect different goods.

[0045] Working principle:

[0046] Step 1: First, place the goods at the bottom of the hanging tray 24. Move the first slider 242 according to the size of the goods. When moving, pull down the second pull plate 248. The second pull plate 248 drives the third locking rod 247 and the protective connecting sleeve rod 245 to move downward. The third locking rod 247 is separated from the hanging tray 24. The protective connecting sleeve rod 245 slides at the bottom of the first slider 242 and pulls the second spring 246. At this time, move the second pull plate 248. The second pull plate 248 drives the lifting rope 243 and the first slider 242 to slide along the track of the third chute 241 to adjust the position of the first slider 242. When the appropriate position is adjusted, release the second pull plate 248. The second spring 246 rebounds to drive the protective connecting sleeve rod 245 to rise. The protective connecting sleeve rod 245 drives the third locking rod 247 to be clamped on both sides of the third chute 241 of the hanging tray 24, thereby fixing the first slider 242.

[0047] Step 2: Next, pull and rotate the turntable 236 according to the position of the goods. The turntable 236 drives the second locking rod 237 to be separated from the air deflector 22. The turntable 236 rotates to drive the winding rod 231 to rotate. The winding rods 231 are connected to each other through a universal shaft 234. Therefore, several winding rods 231 rotate synchronously. The winding rod 231 rotates to unwind the limit rope 232. At this time, the first lock 233 approaches the goods and latches with the goods. Then reverse the turntable 236 to make the winding rod 231 in a taut state. Then push the turntable 236 to make the second locking rod 237 snap into the air deflector 22 to limit the turntable 236.

[0048] Step 3: Pull the first pull plate 229 according to the height of the goods. The first pull plate 229 drives the first locking rod 2291 to be separated from the air deflector 22, and deflect the first pull plate 229. At this time, the first locking rod 2291 loses its fixation. Pull down the telescopic plate 228. The telescopic plate 228 extends from the air deflector 22, and its height is equal to that of the goods. Then pull the first pull plate 229 again and reverse it. After aligning the clamping position of the first locking rod 2291 with the air deflector 22, release it, so that the first spring 2293 pulls the first pull plate 229 to drive the first locking rod 2291 to be clamped and fixed with the air deflector 22 again.

[0049] Step 4: When transporting the goods, start the motor 225. The motor 225 drives the rotating shaft 224 to rotate. The rotating shaft 224 drives the gear 223 to rotate. The gear 223 drives the toothed ring 222 to rotate. The toothed ring 222 drives the support slider 221 to rotate. The support slider 221 drives the air deflector 22 to move along the track of the first chute 211, so that the convex surface of the air deflector 22 faces the moving direction. And the wind generated by the movement blows to both sides along the inclined surface of the air deflector 22. And when there is a crosswind during transportation, the position of the air deflector 22 can be adjusted to face the crosswind. Among them, the first lock 233 can pull and limit the goods. When the position of the air deflector 22 is adjusted, the fixed box 23 drives the goods to rotate through the first lock 233.
