Description

Technical Field

[0001] This utility model relates to the field of heavy-duty drone transportation technology, and more specifically, it relates to a heavy-duty drone transportation device. Background Technology

[0002] In the field of drone applications, heavy-duty transport drones, as emerging intelligent transportation equipment, have their loading capacity and transportation efficiency directly related to the effectiveness and economic benefits of logistics and distribution. However, the heavy-duty drone transportation devices currently on the market have significant technical defects in terms of the practicality and reliability of their mounting systems. These problems not only affect operational efficiency but may also bring serious safety hazards.

[0003] The primary problem is the cumbersome installation and disassembly process. Existing heavy-duty drone transport devices present significant operational obstacles: First, the connection points between the traditional mounting bracket and the drone body are often distributed at different locations on the bottom of the drone, some even in hard-to-reach areas; second, fixing each connection point often requires different types of specialized tools, such as wrenches, screwdrivers, and Allen wrenches, increasing the burden of carrying and managing tools; third, operators need to repeatedly change tools for loading and unloading in confined spaces, which not only increases labor intensity but also prolongs takeoff preparation time; finally, this cumbersome installation and disassembly process not only reduces task switching efficiency but also increases labor costs, and may even cause mission delays in emergency situations.

[0004] More seriously, the connection is unstable. Although some improved heavy-duty UAVs have achieved rapid loading and unloading functions, they suffer from key defects in structural reliability: First, rapid connection structures often pursue overly simplified designs and lack necessary anti-loosening and self-locking mechanisms; second, during flight, UAVs are subjected to continuous vibration, airflow disturbances, and attitude changes; third, the gravitational impact and inertia during loading will generate enormous stress on the connection structure; in addition, frequent take-off and landing operations will also lead to fatigue wear of the connection components; finally, this structural instability will not only cause the pylon to sway during flight, affecting flight attitude and control precision, but may also lead to connection failure in extreme cases, causing the pylon and cargo to fall off, resulting not only in economic losses but also potentially serious safety accidents, posing a significant threat to personnel and property on the ground.

[0032] A protective plate 27 is rotatably connected to one side of the mounting frame 22, and multiple connecting plates 24 are respectively connected to the protective plate 27 and the corresponding position on one side of the mounting frame 22.

[0033] In this embodiment, when the device is needed, firstly, a suitable mounting frame 22 is selected, and the connecting plate 24 connected to the top of the top frame 23 is aligned with the connecting plate 24 set below the drone 1.

Then, the drone 1 is driven so that the drone 1 drives the mounting frame 22 for transportation.

[0034] Please see Figures 3-5 As a further implementation of the overall device: a slider 28 is fixedly provided on the inner side of the locking sleeve 10, and a groove 29 is provided on the outer side of the fixing sleeve 4, and the slider 28 slides in the groove 29.

[0035] A locking wheel 30 is provided on one side of the locking block 19, which can be rotated to engage between the two corresponding limiting blocks 17.

[0036] The release sleeve 3 is connected to a plurality of locking rails 31 on one side, and the locking block 19 is provided with a locking groove 32, which is adapted to the locking rail 31.

[0037] A push spring 33 is connected to one side of the snap-fit ​​block 5, and the other end of the push spring 33 is connected to the inner wall of the contact sleeve.

[0038] A top spring 34 is movably sleeved on the outer side of the connecting rod 20. One end of the top spring 34 is connected to the locking sleeve 10, and the other end of the top spring 34 is in contact with the movable plate 11.

[0039] More specifically, when it is necessary to remove the fixing sleeve 4 and the fixing rod 2, first rotate the movable plate 11 in the forward direction. The movable plate 11 drives the movable block 14 installed on one side to rotate, so that the movable block 14 and the fixing block 13 cooperate to compress the movable spring 15. At the same time, the movable plate 11 will drive the movable hole 16 and the movable groove 12 to rotate in the forward direction. When the movable spring 15 is compressed to the limit, the movable hole 16 just rotates to the position concentric with the support plate 21. Then push the locking sleeve 10, so that the locking sleeve 10 drives the slider 28 to slide along the slide groove 29. Then the locking sleeve 10 drives the two support plates 21 to slide into the movable hole 16 through the connecting rod 20. The locking sleeve 10 cooperates with the movable plate 11 to compress the top spring 34. When the top spring 34 is compressed to the limit, it approaches the locking sleeve 1. One of the support plates 21 completely passes through the movable hole 16 and moves to the other side of the movable plate 11. Then the movable plate 11 is released, and the movable spring 15 pushes the movable block 14 to rotate in the opposite direction. Then the movable block 14 drives the movable hole 16 and the movable groove 12 to rotate in the opposite direction through the movable plate 11. Then the connecting rod 20 will enter the movable hole 16. Then the locking sleeve 10 no longer limits the locking wheel 30. Then the release sleeve 3 rotates in the forward direction. The release sleeve 3 drives the locking block 19 to rotate in the forward direction through the locking rail 31 and the locking groove 32 set on one side. Then the locking block 19 drives the locking wheel 30 to rotate in the forward direction, so that the locking wheel 30 rolls out between the two limiting blocks 17. Then the locking wheel 30 drives the locking block 19 to slide outward along the locking rail 31 and the locking groove 32, and the locking... The positioning block 19 pulls the locking spring 18 outward, while the release sleeve 3 drives the release groove 8 on the inner side to rotate in the forward direction. Then, the release groove 8 drives the locking block 5 to rotate through the rotating shaft 7. Then, one side of the inner wall of the mating groove 6 limits one side of the locking block 5, so that the locking block 5 rotates out of the fixing groove 9 along the rotating shaft 7. Then, the locking block 5 will gradually rotate into the release groove 8 and squeeze the push spring 33 on one side. Then, the fixing sleeve 4 and the fixing rod 2 are pulled to both ends respectively, and the fixing sleeve 4 and the fixing rod 2 can be removed. When it is necessary to reconnect the fixing sleeve 4 and the fixing rod 2, first, pass the fixing rod 2 through the connecting plate 24 from one side, and then put the fixing sleeve 4 on the outside of the fixing rod 2 from the other side. Then, rotate the release sleeve 3 in the opposite direction. The release groove 8 drives the rotating shaft 7 to rotate and reset. Then, the rotating shaft 7 and the release groove 8 cooperate to drive the locking block 5 to move and reset. Then, one side of the inner wall of the mating groove 6 gradually stops limiting one side of the locking block 5. Then, the push spring 33 pushes the locking block 5, so that the locking block 5 gradually rotates out of the release groove 8 and into the fixing groove 9 along the rotating shaft 7. At the same time, the locking rail 31 and the locking groove 32 cooperate to drive the locking block 19 and the locking wheel 30 to rotate and reset between the two original limiting blocks 17. Then, the locking spring 18 resets and pulls the locking block 19 to slide inward along the locking rail 31 and the locking groove 32. Then, the locking block 19 drives the locking wheel 30 to lock between the two original limiting blocks 17. Then, the movable plate 11 is rotated forward again, and the movable plate 11 drives the movable block 14 to rotate forward again.Then, the movable block 14 and the fixed block 13 cooperate again to press the movable spring 15, and the movable plate 11 drives the movable hole 16 and the movable groove 12 to rotate in the forward direction again. When the movable hole 16 rotates to the position concentric with the support plate 21, the top spring 34 pushes the locking sleeve 10 to slide back to its original position, so that the locking sleeve 10 drives the two support plates 21 to slide back to their original position through the connecting rod 20. When the top spring 34 is fully reset, the support plate 21 set at the top of the connecting rod 20 moves to the original side of the movable plate 11, and then the movable plate 11 is released. The movable spring 15 pushes the movable block 14 to rotate back to its original position, and then the movable block 14... 4. The movable plate 11 drives the movable hole 16 and movable groove 12 to rotate and reset to a position that does not correspond to the connecting rod 20 and the support plate 21. Then, the connecting rod 20 and the top support plate 21 cooperate to support and limit the locking sleeve 10. Combined with the slider 28 and the sliding groove 29 limiting the locking sleeve 10, the locking sleeve 10 cannot slide. Then, the inner wall of the locking sleeve 10 limits the outer wall of the locking wheel 30, preventing the locking wheel 30 and the locking block 19 from sliding outwards. This limits the release sleeve 3, preventing it from rotating, thus ensuring the stability of the installation structure and ensuring stable use of the equipment.

[0040] In summary, when using or operating the equipment: First, select a suitable mounting frame 22, align the connecting plate 24 connected to the top of the top frame 23 with the connecting plate 24 located below the drone 1, and then fix it to the bottom of the drone 1 using the fixing sleeve 4 and fixing rod 2. Next, select a suitable support frame 26 and connect it to the bottom of the bracket 25, so that the bottom end of the support frame 26 bears the load and limits the bottom end of the mounting frame 22. Then, remove the fixing sleeve 4 and fixing rod 2 located on one side of the protective plate 27, open the protective plate 27, place the items to be transported inside the mounting frame 22, close the protective plate 27 again, and then fix the protective plate 27 and the connecting plate 24 located on one side of the mounting frame 22 using the two sets of fixing sleeves 4 and fixing rod 2. Then, drive the drone 1 so that the drone 1 can carry the mounting frame 22 for transportation.

[0041] When it is necessary to remove the fixing sleeve 4 and the fixing rod 2, first rotate the movable plate 11 clockwise. The movable plate 11 drives the movable block 14 installed on one side to rotate, so that the movable block 14 and the fixing block 13 cooperate to compress the movable spring 15. At the same time, the movable plate 11 will drive the movable hole 16 and the movable groove 12 to rotate clockwise. When the movable spring 15 is compressed to the limit, the movable hole 16 just rotates to the position concentric with the support plate 21. Then push the locking sleeve 10, so that the locking sleeve 10 drives the slider 28 to slide along the slide groove 29. Then the locking sleeve 10 drives the two support plates 21 to slide into the movable hole 16 through the connecting rod 20. The locking sleeve 10 cooperates with the movable plate 11 to compress the top spring 34. When the top spring 34 is compressed to the limit, one of the points near the locking sleeve 10 The support plate 21 passes completely through the movable hole 16 and moves to the other side of the movable plate 11. Then the movable plate 11 is released, and the movable spring 15 pushes the movable block 14 to rotate in the opposite direction. Then the movable block 14 drives the movable hole 16 and the movable groove 12 to rotate in the opposite direction through the movable plate 11. Then the connecting rod 20 will enter the movable hole 16. Then the locking sleeve 10 no longer limits the locking wheel 30. Then the release sleeve 3 rotates in the forward direction. The release sleeve 3 drives the locking block 19 to rotate in the forward direction through the locking rail 31 and the locking groove 32 set on one side. Then the locking block 19 drives the locking wheel 30 to rotate in the forward direction, so that the locking wheel 30 rolls out between the two limiting blocks 17. Then the locking wheel 30 drives the locking block 19 to slide outward along the locking rail 31 and the locking groove 32. 19 pulls the locking spring 18 outward, and at the same time, the release sleeve 3 will drive the release groove 8 opened on the inner side to rotate in the forward direction. Then, the release groove 8 drives the locking block 5 to rotate through the rotating shaft 7. Then, one side of the inner wall of the mating groove 6 limits one side of the locking block 5, so that the locking block 5 rotates out of the fixing groove 9 along the rotating shaft 7. Then, the locking block 5 will gradually rotate into the release groove 8 and squeeze the push spring 33 set on one side. Then, the fixing sleeve 4 and the fixing rod 2 are pulled to both ends respectively, and the fixing sleeve 4 and the fixing rod 2 can be removed. When it is necessary to reconnect the fixing sleeve 4 and the fixing rod 2, first pass the fixing rod 2 through the connecting plate 24 from one side, and then put the fixing sleeve 4 on the outside of the fixing rod 2 from the other side. Then rotate the release sleeve 3 in the opposite direction. The release sleeve 3 releases the locking spring 2 through the locking spring 9. The release groove 8 drives the rotating shaft 7 to rotate and reset. Then, the rotating shaft 7 and the release groove 8 cooperate to drive the locking block 5 to move and reset. Then, one side of the inner wall of the mating groove 6 gradually stops limiting the locking block 5. Then, the push spring 33 pushes the locking block 5, so that the locking block 5 gradually rotates out of the release groove 8 and into the fixing groove 9 along the rotating shaft 7. At the same time, the locking rail 31 and the locking groove 32 cooperate to drive the locking block 19 and the locking wheel 30 to rotate and reset between the two original limiting blocks 17. Then, the locking spring 18 resets and pulls the locking block 19 to slide inward along the locking rail 31 and the locking groove 32. Then, the locking block 19 drives the locking wheel 30 to lock between the two original limiting blocks 17. Then, the movable plate 11 is rotated forward again, and the movable plate 11 drives the movable block 14 to rotate forward again.Then, the movable block 14 and the fixed block 13 cooperate again to press the movable spring 15, and the movable plate 11 drives the movable hole 16 and the movable groove 12 to rotate in the forward direction again. When the movable hole 16 rotates to the position concentric with the support plate 21, the top spring 34 pushes the locking sleeve 10 to slide back to its original position, so that the locking sleeve 10 drives the two support plates 21 to slide back to their original position through the connecting rod 20. When the top spring 34 is fully reset, the support plate 21 set at the top of the connecting rod 20 moves to the original side of the movable plate 11, and then the movable plate 11 is released. The movable spring 15 pushes the movable block 14 to rotate back to its original position, and then the movable block 14... 4. The movable plate 11 drives the movable hole 16 and movable groove 12 to rotate and reset to a position that does not correspond to the connecting rod 20 and the support plate 21. Then, the connecting rod 20 and the top support plate 21 cooperate to support and limit the locking sleeve 10. Combined with the slider 28 and the sliding groove 29 limiting the locking sleeve 10, the locking sleeve 10 cannot slide. Then, the inner wall of the locking sleeve 10 limits the outer wall of the locking wheel 30, preventing the locking wheel 30 and the locking block 19 from sliding outwards. This limits the release sleeve 3, preventing it from rotating, thus ensuring the stability of the installation structure and ensuring stable use of the equipment.
