[0003] After receiving the container dispatch command, the drone flies to a designated altitude above the docking warehouse. The docking warehouse transmits positioning signals to the drone via laser positioning modules and simultaneously receives position feedback from the drone, initially calibrating the spatial position between the drone and the docking warehouse. Subsequently, the drone descends to the sensing area of ​​the docking warehouse's centering platform. The platform's limit and guidance structure is activated, correcting the drone's horizontal deviation in real time and forcibly adjusting the drone's fuselage or the docking position of the warehouse to the standard docking point at the very center of the platform, completing precise centering.

[0004] However, drone containers of different sizes require customized centering mechanisms, resulting in high manufacturing costs. Existing drone centering mechanisms cannot be matched with docking platforms for drone containers of different sizes, severely limiting their application scope and exhibiting poor versatility.

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a drone cargo container centering mechanism, including a frame structure 1, a drive structure 2, and a connecting structure 3.

[0020] It should be further explained that the frame structure 1 includes four sets of telescopic components 1 fixedly connected end to end, which together form a square shape. Each telescopic component 1 includes a sleeve 11; a sliding rod 12 is slidably connected inside the sleeve 11. The ends of the sleeve 11 / sliding rod 12 are fixedly connected to the ends of the sleeve 11 / sliding rod 12 in the adjacent telescopic component 1. Sliding grooves 15 are respectively provided on the side walls of the sleeve 11 and the sliding rod 12; two sets of push rods 16 are arranged between the two sets of telescopic components 1 at intervals, and the two sets of push rods 16 are parallel to each other. Sliding blocks 17 are fixedly connected to both ends of the two sets of push rods 16; the sliding blocks 17 are slidably connected in the corresponding side sliding grooves 15, making the distance between the two sets of push rods 16 adjustable. Multiple sets of insertion holes 13 are equidistantly provided on the upper end of the sliding rod 12; a slot is provided on the upper end of the sleeve 11; insertion rods 14 are inserted into the insertion holes 13 and slots. By pulling the slide bar 12, the slide bar 12 slides within the sleeve 11, thereby adjusting the length of the telescopic component 1, and thus adjusting the size of the frame structure 1, so that the frame structure 1 can match the docking platform of drone containers of different sizes. Next, the insertion rod 14 is inserted into the slot and the corresponding insertion hole 13 in sequence, thereby fixing the length of the telescopic component 1 and preventing changes in the size of the frame structure 1.

[0021] It should be further explained that the drive structure 2 is provided in two sets, and is respectively arranged between two sets of telescopic members 1 that are spaced apart. The drive structure 2 includes sprockets 23 that are rotatably connected to the side walls of the sleeve 11 and the slide rod 12 in the same set of telescopic members 1; a chain drive component is provided between the two sets of sprockets 23; the chain drive component is composed of multiple sets of detachable chain link units.

[0022] It should be further explained that the drive structure 2 also includes two sets of telescopic components II; the telescopic components II and the corresponding telescopic components I are perpendicular to each other, and their ends are rotatably connected to the corresponding telescopic components I. The telescopic component II includes a sleeve II 21; a sliding rod II 22 is slidably connected inside the sleeve II 21; the ends of the sleeve II 21 / sliding rod II 22 are rotatably connected to the side walls of the corresponding sleeve I 11 / sliding rod I 12. The sleeve II 21 and the sliding rod II 22 are coaxially connected to the corresponding side sprockets 23. The drive structure 2 also includes a motor 24; the motor 24 is mounted on the telescopic component I (sleeve I 11 / sliding rod I 12); the drive end of the motor 24 is coaxially connected to one of the sprockets 23. By starting the motor 24, the connected sprocket 23 is driven to rotate, thereby driving the corresponding sleeve II 21 and sliding rod II 22 to rotate synchronously, which in turn drives the sprockets 23 on both sides of the telescopic component II to rotate synchronously.

[0023] It should be further explained that the link unit includes two sets of parallel side plates 25; two sets of parallel connecting rods 26 are fixedly connected between the two sets of side plates 25. Each end of one side plate 25 has a second insertion hole 27; each end of the other side plate 25 has a second insertion rod 28 fixedly attached; the second insertion rod 28 engages with the second insertion hole 27 on the side plate 25 of the adjacent link unit. The entire link unit is made of silicone. By inserting the second insertion rod 28 of this link unit into the corresponding second insertion hole 27 of the adjacent link unit, and vice versa, this link unit and the adjacent link unit can be fixedly connected. A protrusion 29 is fixedly connected to the end of the second insertion rod 28 facing away from the side plate 25 to prevent the second insertion rod 28 from detaching from the second insertion hole 27. By connecting multiple sets of link units end-to-end in the above manner, a chain drive component can be formed. The chain drive component is wound around the outside of two sets of sprockets 23 located on the side walls of the sleeve 11 and slide rod 12 in the same group of telescopic components, and is engaged with the two sets of sprockets 23 respectively. The length of the chain drive component can be adjusted to match telescopic components of different lengths.

[0024] It should be further explained that the connecting structure 3 is set on the slider 17 to fix the slider 17 and the corresponding link unit. The connecting structure 3 includes a connecting belt 31; one end of the connecting belt 31 is hinged to the slider 17, and the other end is hinged to a connecting frame 32; the connecting frame 32 is U-shaped, and a positioning plate 33 is fixedly connected to its middle part. The width of the positioning plate 33 is equal to the distance between the two sets of connecting rods 26. The two ends of the connecting frame 32 and the ends of the positioning plate 33 are respectively fixedly connected to the fixing cylinders 34; insert strips 35 are inserted into the multiple fixing cylinders 34. The insert strips 35 are threaded rods; the fixing cylinders 34 have threaded grooves that mate with the insert strips 35. By embedding the link unit into the connecting frame 32, inserting the positioning plate 33 between the two sets of side plates 25 and the two sets of connecting rods 26, and then inserting the insert strips 35 into the fixing cylinders 34, the insert strips 35 are threadedly connected to the fixing cylinders 34, thereby fixing the slider 17 and the corresponding link unit. When connecting slider 17 to the corresponding chain link unit, the connecting structure 3 on one side of slider 17 should be connected to the upper side of the chain drive component, and the connecting structure 3 on the other side of slider 17 should be connected to the lower side of the chain drive component, so that when the chain drive component is in motion, the two sets of push rods 16 can move in opposite directions.

[0025] By coordinating the frame structure 1, drive structure 2, and connection structure 3, this drone container centering mechanism can be matched with drone container docking warehouse platforms of different sizes, significantly reducing the customized design and manufacturing costs for different scenarios and improving the modular performance and flexibility of the mechanism. Furthermore, the overall assembly is quick and convenient, shortening the deployment cycle and improving installation efficiency.

[0026] The working principle of this invention is as follows: During assembly, pull the slide bar 12 to allow it to slide within the sleeve 11, thereby adjusting the length of the telescopic component 1 and consequently the size of the frame structure 1. This allows the frame structure 1 to be compatible with docking platforms for drone containers of different sizes. Next, insert the insertion rod 14 into the slot and corresponding insertion hole 13 in sequence to fix the length of the telescopic component 1, preventing changes in the size of the frame structure 1.

[0027] Next, multiple chain link units are assembled into a chain drive component, ensuring the length of the chain drive component matches the spacing between the two sets of sprockets 23. Insert the insert rod 28 from this chain link unit into the corresponding insert hole 27 in the adjacent chain link unit, and vice versa, thus fixing the chain link unit and the adjacent chain link unit together. By sequentially connecting multiple chain link units end-to-end in the above manner, a chain drive component can be formed. The chain drive component is then wound around the outside of the two sets of sprockets 23 and engaged with each of the two sets of sprockets 23.

[0028] Finally, the link unit corresponding to the slider 17 is embedded into the connecting frame 32, and the positioning plate 33 is inserted between the two sets of side plates 25 and the two sets of connecting rods 26. Then, the insert strip 35 is inserted into the fixing cylinder 34, so that the insert strip 35 is threadedly connected to the fixing cylinder 34, thereby fixing the slider 17 and the corresponding link unit.

[0029] During operation, the motor 24 can be started to drive the connected sprocket 23 to rotate, thereby driving the corresponding sleeve 21 and slide rod 22 to rotate synchronously, which in turn drives the sprockets 23 on both sides of the telescopic component 2 to rotate synchronously. The rotation of the sprockets 23 on both sides can also drive the two sets of chain drive components to drive the two sets of push rods 16 arranged between the two sets of telescopic components 1 to move in opposite directions, and push the drone between them to move, correct the horizontal deviation of the drone in real time, and force the drone body to be adjusted to the center position.

[0030] By coordinating the frame structure 1, drive structure 2, and connection structure 3, this drone container centering mechanism can be matched with drone container docking warehouse platforms of different sizes, significantly reducing the customized design and manufacturing costs for different scenarios and improving the modular performance and flexibility of the mechanism. Furthermore, the overall assembly is quick and convenient, shortening the deployment cycle and improving installation efficiency.

[0031] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
