Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) cargo carrying technology, and in particular to a UAV cargo carrying device for transportation. Background Art

[0002] Unmanned aerial vehicles (UAVs) are referred to as "drones" and are unmanned aerial vehicles that are controlled by radio remote control equipment and self-contained program control devices. UAVs are actually a general term for unmanned aerial vehicles. Compared with manned aircraft, UAVs have the advantages of small size, low cost, easy use, low requirements for combat environment, and strong battlefield survivability. For example, the patent with announcement number CN218022192U discloses a detachable cargo hold for logistics UAVs, including a UAV body, a cargo hold, an adapter bracket and a connecting mounting bracket. The cargo hold is set below the UAV body, and the adapter bracket and the connecting mounting bracket are connected to the UAV body. The brackets are all arranged above the cargo bin, and the external top end of the cargo bin is fixedly connected to an adapter bracket, the front end of the adapter bracket is provided with a through slot, and the rear end of the adapter bracket is fixedly connected to a mounting block, and the external bottom end of the mounting block is fixedly connected to the external top end of the cargo bin. The device is provided with a connecting mounting bracket and an adapter bracket. After the bolts provided on the surface of the adapter bracket are removed, the mounting block provided in the connecting mounting bracket is movable in the mounting slot by cooperating with the pull ring, spring, block and mounting slot provided in the connecting mounting bracket. Finally, the operator pushes it to detach the cargo bin. Although the detachment of the cargo bin can be achieved, it requires manual operation by the operator, which is relatively cumbersome to use. In addition, the cargo bin cannot fall off automatically, and thus cannot be airdropped, resulting in a small scope of application of the device. In addition, when the drone lands, the cargo bin first contacts the ground, causing the cargo bin to easily collide with the ground, thereby causing damage to the cargo bin or the items in the cargo bin.

[0003] To this end, the present invention provides a cargo carrying device for a transport drone. Summary of the Invention

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] See also Figures 1 to 12The present invention provides a technical solution: a transport drone cargo device, comprising a drone 1, a drive box 2 fixed to the lower side of the drone 1, support frames 9 slidingly fitted on both sides of the drive box 2, a first cargo box 13 mounted on the lower side of the drive box 2, a second cargo box 14 mounted on the lower side of the first cargo box 13, a snap-fit fixing structure mounted between the first cargo box 13 and the drive box 2, a positioning fixing structure mounted between the first cargo box 13 and the second cargo box 14, the positioning fixing structure corresponding to the support frame 9, and the first cargo box 13 and the second cargo box 14 having the same structure. The first cargo box 13 and the second cargo box 14 both include a box body and a box cover 43. The first cargo box 13 and the second cargo box 14 are equipped with airbags 25 and a clamping and fixing structure. The clamping and fixing structure includes a lower pressure plate 26 and a side pressure plate 27. The first cargo box 13 and the second cargo box 14 are both equipped with a first buffer plate 31 and a second buffer plate 32 on the surrounding sides. The first buffer plate 31 corresponds to the side pressure plate 27. Elastic connection structures are installed between the side pressure plate 27 and the box body and the box cover 43. A locking structure is installed between the box cover 43 and the box body, and the locking structure corresponds to the side pressure plate 27.

[0035] In this embodiment, there are two sliding plates 8 that slide in the drive box 2, and the sliding plates 8 are fixedly connected to the support frame 9. There are two screws 5 that rotate in the drive box 2, and the screws 5 are threadedly engaged with the sliding plates 8. The end of the screw 5 is fixed with a first gear 6. A motor 3 is fixed in the drive box 2, and a rotating shaft 4 is fixed to the output end of the motor 3. A second gear 7 is fixed to the end of the rotating shaft 4, and the second gear 7 is meshed with the first gear 6.

[0036] Specifically, the support frame 9 slides on both sides of the drive box 2, and the two first gears 6 are respectively located on both sides of the second gear 7. The motor 3 is started, so that the motor 3 drives the rotating shaft 4 to rotate, thereby driving the second gear 7 to rotate, so that the second gear 7 engages and rotates with the first gear 6, thereby driving the screw 5 to rotate. At this time, the drive box 2 limits the sliding plate 8 so that the sliding plate 8 cannot rotate with the rotation of the screw 5, thereby driving the sliding plate 8 to slide in the drive box 2, and the support frame 9 can be driven to move by the sliding plate 8, so that the two support frames 9 are close to or away from each other, thereby realizing the clamping, fixation and delivery of the second cargo box 14.

[0037] A first pressure rod 10 and multiple second pressure rods 11 are fixed on the support frame 9. A limiting plate 12 is fixed to the end of the first pressure rod 10. The limiting plate 12 corresponds to the positioning and fixing structure and the first buffer plate 31 located on the side of the first cargo box 13. The second pressure rod 11 corresponds to the first buffer plate 31 located on the side of the second cargo box 14.

[0038] Specifically, when the two support frames 9 approach each other, the support frame 9 drives the limit plate 12 to approach the box body, so that the limit plate 12 contacts the first buffer plate 31. As the two support frames 9 approach each other, the support frame 9 drives the limit plate 12 to squeeze the first buffer plate 31 located on the side of the first cargo box 13, so that the first buffer plate 31 located on the side of the first cargo box 13 contacts the first cargo box 13. At the same time, the support frame 9 drives the second pressure rod 11 to pass through the first buffer plate 31 located on the side of the second cargo box 14 and contact the second cargo box 14, so that the first cargo box 13 and the second cargo box 14 can be limited, which can ensure that the first cargo box 13 and the second cargo box 14 are in a relatively static state with the drone 1, thereby ensuring the stability of cargo transportation.

[0039] The positioning and fixing structure includes a panel 20 fixed on the second cargo box 14, and a third buffer plate 44 is elastically fitted on the lower side of the first cargo box 13, and the third buffer plate 44 corresponds to the panel 20. A first through groove 21 is provided on the panel 20, and a slot 22 is provided in the third buffer plate 44. An insert block 23 is fixed on the limiting plate 12, and the insert block 23 corresponds to the first through groove 21 and the slot 22.

[0040] Specifically, when there are many objects to be transported, a second cargo box 14 can be installed on the lower side of the first cargo box 13, and the second cargo box 14 can be placed on the lower side of the first cargo box 13, so that the third buffer plate 44 enters the relative inner side of the enclosure 20, and then the motor 3 is started to make the two support frames 9 approach each other, thereby pushing the limit plates 12 closer to each other, which can drive the plug block 23 to move, so that the plug block 23 passes through the first through groove 21 and enters the slot 22, so that the plug block 23 and the slot 22 have a snap-fit relationship, so that the first cargo box 13 and the second cargo box 14 can be connected together, so that the goods can be transported through the first cargo box 13 and the second cargo box 14.

[0041] The first spring 30 is fixed on the second buffer plate 32 and the third buffer plate 44. A plurality of second through slots 24 are provided in the first buffer plate 31 located on the side of the second cargo box 14. The second through slots 24 correspond to the second pressure rod 11. The second pressure rod 11 is in contact with the second cargo box 14. A plurality of first damping blocks 34 are fixed on the second buffer plate 32 and the third buffer plate 44.

[0042] Specifically, buffering can be performed by the first buffer plate 31, the second buffer plate 32 and the third buffer plate 44. When the first cargo box 13 or the second cargo box 14 falls to the ground, the third buffer plate 44 first contacts the ground, so that the third buffer plate 44 is squeezed upward relative to the box body, the first spring 30 is compressed, and the third buffer plate 44 squeezes the first damping block 34, thereby achieving a certain shock-absorbing effect.

[0043] Specifically, when the box is being dropped, the entire center of gravity is downward, so under normal circumstances the third buffer plate 44 first contacts the ground, so that the third buffer plate 44 is squeezed upward relative to the box, the first spring 30 is compressed, and the third buffer plate 44 squeezes the first damping block 34, thereby achieving a certain shock-absorbing effect. At this time, the larger impact causes the box to rebound upward, and the center of gravity of the box is downward, thereby reducing the possibility of the box flipping over.

[0044] When the box flips over under extreme circumstances, the first buffer plate 31 or the second buffer plate 32 may contact the ground. When the second buffer plate 32 contacts the ground, the second buffer plate 32 squeezes the first spring 30 and the first damping block 34, thereby performing shock absorption and buffering; when the first buffer plate 31 contacts the ground, the first buffer plate 31 drives the side pressure plate 27 to move, thereby stretching the second spring 33, and the first buffer plate 31 squeezes the second damping block 35, thereby performing shock absorption and buffering.

[0045] When the side of the box away from the third buffer plate 44 contacts the ground, the box rebounds under the buffering of the third buffer plate 44. The box is already very close to the ground. Although there is no buffer structure outside the box, the lower height is not enough to cause damage to the box. Therefore, the impact force can be borne by the box itself, and the airbag 25 and elastic telescopic rod 28 inside the box can protect the objects inside the box.

[0046] The clamping and fixing structure includes a connecting block 15 fixed on the first cargo box 13, a first clamping groove 16 is provided in the connecting block 15, a first groove 19 is provided in the drive box 2, the first groove 19 corresponds to the connecting block 15, a first clamping block 17 is elastically fitted in the first groove 19, the first clamping block 17 corresponds to the first clamping groove 16, an electromagnet 18 is fixed in the first groove 19, the electromagnet 18 corresponds to the first clamping block 17, and a fourth spring is fixed between the first clamping block 17 and the first groove 19.

[0047] Specifically, when the first cargo box 13 needs to be unloaded, the electromagnet 18 is energized so that the electromagnet 18 adsorbs the first clamping block 17, thereby driving the first clamping block 17 to slide, and the fourth spring is compressed, so that the first clamping block 17 loses the clamping relationship with the first clamping slot 16, so that the drive box 2 no longer limits the first cargo box 13, and the first cargo box 13 can be disassembled.

[0048] A plurality of elastic telescopic rods 28 are installed between the lower pressure plate 26 and the box body, and the two ends of the elastic telescopic rods 28 are fixedly connected to the lower pressure plate 26 and the inner wall of the box body respectively. The elastic connection structure includes a plurality of second springs 33 fixed between the side pressure plate 27 and the box body and a plurality of second springs 33 fixed between the side pressure plate 27 and the box cover 43. A plurality of connecting rods 29 are fixed between the first buffer plate 31 and the side pressure plate 27. The plurality of connecting rods 29 are slidably connected to the box body and the box cover 43 respectively. A second damping block 35 is fixed on the first buffer plate 31.

[0049] Specifically, the elastic telescopic rod 28 pushes the lower pressing plate 26 so that the lower pressing plate 26 presses downward to fix the goods in the box, inflates the airbag 25, and makes the airbag 25 swell, thereby protecting the objects in the box.

[0050] When the two limit plates 12 approach each other, the first buffer plate 31 can be pushed by the limit plate 12, so that the first buffer plate 31 pushes the side pressure plate 27 through the connecting rod 29 until the two side pressure plates 27 contact the object, and the second spring 33 is stretched, thereby clamping and fixing the object; when the two limit plates 12 move away from each other, the limit plate 12 no longer limits the first buffer plate 31, so that the second spring 33 rebounds, causing the limit plate 12 to reset, and the first buffer plate 31 can be used for buffering during airdrop.

[0051] A push rod 36 is fixed on the upper and lower sides of the side pressure plate 27 located on one side of the box cover 43. The locking structure includes two push blocks 42, which are respectively located on the upper and lower sides of the box cover 43. The push blocks 42 correspond to the push rod 36. The locking structure also includes a second card slot 37 opened on the upper and lower sides of the box cover 43. A second groove 38 is opened in the box body. A second card block 40 is installed in the second groove 38. A third spring 39 is fixed between the second card block 40 and the groove wall of the second groove 38. The second card block 40 corresponds to the second card slot 37. A slide groove 41 is opened in the box body. The slide groove 41 is connected to the second groove 38. The slide groove 41 corresponds to the push block 42. The push block 42 is fixedly connected to the second card block 40. The force exerted by the third spring 39 is much greater than that of the second spring 33.

[0052] Specifically, when it is necessary to take out an object in the box, the first buffer plate 31 is pulled, so that the first buffer plate 31 pushes the side pressure plate 27 through the connecting rod 29, thereby driving the push rod 36 on the side pressure plate 27 to move, so that the push rod 36 squeezes the push block 42, and the push block 42 slides relatively upward in the slide groove 41. The push block 42 drives the second clamping block 40 to completely enter the second groove 38, and the third spring 39 is compressed, so that the second clamping block 40 loses the clamping relationship with the second clamping groove 37, so that the box cover 43 can be removed and the object in the box can be taken out.

[0053] In particular, the object can be placed in the storage box, and then the storage box can be placed in the box body, so that the object can be doubly protected by the box body and the storage box, thereby ensuring the transportation safety of the object.

[0054] Workflow: Place the object in the storage box, then place the storage box in the box body, then place the first cargo box 13 on the lower side of the drive box 2, insert the connecting block 15 into the first groove 19, cut off the power to the electromagnet 18, so that the fourth spring pushes the first card block 17 into the first card slot 16, and the first card block 17 and the first card slot 16 are in a card connection relationship, and the first cargo box 13 can be installed, and then the second cargo box 14 is placed on the lower side of the first cargo box 13, so that the third buffer plate 44 enters the opposite inner side of the enclosure 20, and then start the motor 3, so that the two support frames 9 are close to each other, thereby pushing the limit plates 12 close to each other, which can drive the insertion block 23 to move, so that the insertion block 23 passes through the first through slot 21 and enters the slot 22, so that The plug block 23 and the slot 22 are snapped together, so that the first cargo box 13 and the second cargo box 14 can be connected together, thereby realizing the installation of the second cargo box 14. At the same time, the support frame 9 drives the limiting plate 12 to squeeze the first buffer plate 31 located on the side of the first cargo box 13, so that the first buffer plate 31 located on the side of the first cargo box 13 contacts the first cargo box 13. At the same time, the support frame 9 drives the second pressure rod 11 to pass through the first buffer plate 31 located on the side of the second cargo box 14 and contact the second cargo box 14, thereby realizing the limiting of the first cargo box 13 and the second cargo box 14, which can ensure that the first cargo box 13 and the second cargo box 14 are in a relatively static state with the drone 1, thereby ensuring the stability of cargo transportation.

[0055] When the first cargo box 13 and the second cargo box 14 need to be disassembled, the motor 3 is started at this time, so that the two support frames 9 move away from each other, thereby pulling the limit plates 12 away from each other, and the plug block 23 can be pulled out from the first through groove 21 and the slot 22, so that the plug block 23 loses the snap-fit relationship with the slot 22, so that the second cargo box 14 can be disassembled, and then the electromagnet 18 is energized so that the electromagnet 18 absorbs the first snap-fit block 17, thereby driving the first snap-fit block 17 to slide, and the fourth spring is compressed, so that the first snap-fit block 17 loses the snap-fit relationship with the first slot 16, so that the drive box 2 no longer limits the first cargo box 13, and the first cargo box 13 can be disassembled.

[0056] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
