Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV mounting device for logistics transportation. Background Technology

[0002] With the development and application of drone technology, drones are playing an increasingly important role in the logistics and transportation field. Drones can carry goods for transportation, thereby improving transportation efficiency. Currently, the matching mounting devices are mainly based on the drone model and size. That is, a mounting device is not universally compatible with drones of different models and sizes. Therefore, how to make the mounting device more easily adaptable to drones of different models and sizes has become a problem. Summary of the Invention

[0003] In order to make the mounting device more easily adaptable to drones of different models, sizes and structures, this application provides a drone mounting device for logistics transportation.

[0004] This application provides a drone mounting device for logistics transportation, which adopts the following technical solution: A drone mounting device for logistics transportation, including The box body has an elongated through hole at the top; Two hooks are provided on the top surface of the box and located in the through hole; A bidirectional lead screw is disposed inside the housing, below the through hole, and is rotatably connected to the housing; Two fixing blocks are threadedly connected to two parts of the threads of the bidirectional lead screw, and the two hooks are fixed to the two fixing blocks respectively; A drive assembly, connected to the bidirectional lead screw, is used to drive the bidirectional lead screw to rotate.

[0005] By adopting the above technical solution, the box is used to place materials, and two hooks are set on the fixed block. The drive component drives the bidirectional screw to rotate. During the rotation of the bidirectional screw, the distance between the two hooks can be adjusted. The change in the distance between the two hooks can adapt to drones of different models and sizes, thus making it easier to hang them on drones.

[0006] Optionally, the drive assembly includes a motor disposed inside the housing, a driving bevel gear disposed on the output shaft of the motor, and a driven bevel gear disposed on the bidirectional lead screw; the driving bevel gear meshes with the driven bevel gear.

[0007] By adopting the above technical solution, the rotation of the motor drives the rotation of the active bevel gear, which in turn drives the rotation of the driven bevel gear, which in turn drives the rotation of the bidirectional lead screw, which in turn drives the two fixed blocks to move. This causes the distance between the hooks on the fixed blocks to change, and the forward and reverse rotation of the motor controls the distance between the hooks to become closer or farther. It is more convenient to drive the bidirectional lead screw to rotate through the motor, the active bevel gear, and the driven bevel gear.

[0008] Optionally, each of the two hooks is provided with a limiting block, which is located in the through hole.

[0009] By adopting the above technical solution, when the bidirectional lead screw rotates, it is easy to drive the fixed block to rotate, which in turn causes the hook to rotate or sway in the through hole. The boxes on both sides of the through hole play a blocking role for the limit block, which makes it difficult for the hook to rotate, thus making the hook more stable during movement.

[0010] Optionally, each of the two limiting blocks is provided with a threaded hole, and each of the two hooks is provided with a fixing ring. A bolt is provided inside the fixing ring, and the bolt corresponds to the position of the threaded hole.

[0011] By adopting the above technical solution, after the hook is attached to the drone, the bolt is rotated to screw the bolt into the threaded hole. The bolt and the fixing block are threaded together to form a closed area for the hook, so the hook is not easy to fall off the drone.

[0012] Optionally, either side of the housing parallel to the bidirectional lead screw is an opening, and a baffle is hinged to the housing, with the baffle located at the opening.

[0013] By adopting the above technical solution, the baffle facilitates the placement of materials into the box and prevents the materials inside the box from being moved out of the box. The hinged baffle facilitates the opening and closing of the baffle.

[0014] Optionally, the side wall of the baffle is provided with a buckle, and the outer wall of the housing with the bidirectional lead screw is provided with a retaining ring. The retaining ring is slidably connected to the housing, and the buckle corresponds to the position of the retaining ring.

[0015] By adopting the above technical solution, after the baffle is closed, the retaining ring locks the buckle, and the baffle is fixed to the box body, making it difficult for the baffle to open and the baffle to close more firmly, so that the materials are not easy to fall out of the box body during the transportation of materials.

[0016] Optionally, there are two retaining rings, each located on an outer side wall of the housing perpendicular to the bidirectional lead screw; and there are two buckles, each located on a different side wall of the baffle.

[0017] By adopting the above technical solution, and through the use of two sets of snap rings and buckles, the baffle can be fixed more firmly.

[0018] Optionally, the bottom surface of the housing is provided with support legs.

[0019] By adopting the above technical solution, the outriggers separate the container from the ground, making the container less prone to damage, facilitating the opening of the baffle, and providing a cushioning effect.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The box is used to place supplies. Two hooks are set on the fixed block. The drive component drives the bidirectional lead screw to rotate. During the rotation of the bidirectional lead screw, the distance between the two hooks can be adjusted. The change in the distance between the two hooks can adapt to different models and sizes of drones, making it easier to hang them on the drones.

[0021] 2. The rotation of the motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate. The driven bevel gear then drives the bidirectional lead screw to rotate, which in turn moves the two fixed blocks. This causes the distance between the hooks on the fixed blocks to change. The forward and reverse rotation of the motor controls whether the distance between the hooks is closer or farther. It is more convenient to drive the bidirectional lead screw to rotate via the motor, active bevel gear, and driven bevel gear. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a drone mounting device for logistics transportation.

[0029] Reference Figure 1 and Figure 2 A drone mounting device for logistics transportation includes a housing 1, hooks 2, a bidirectional lead screw 31 disposed within the housing 1, two fixing blocks 32 disposed on the bidirectional lead screw 31, and a drive assembly 4 for rotating the bidirectional lead screw 31. The housing 1 is square, with an internal cavity for placing materials. A long, narrow through hole 11 is formed at the top of the housing 1, and the two hooks 2 are located within the through hole 11. The bidirectional lead screw 31 is located below the through hole 11 and is rotatably connected to the two inner sidewalls of the housing 1. The axis of the bidirectional lead screw 31 is parallel to the through hole 11, and the bidirectional lead screw 31 includes two sets of threaded teeth with opposite directions. Both fixing blocks 32 are threadedly connected to the bidirectional lead screw 31, and are located on the two sets of threads of the bidirectional lead screw 31, with the distances from the midpoint of the bidirectional lead screw 31 to the fixing blocks 32 being the same. The two hooks 2 are fixedly connected to the two fixing blocks 32, with their openings facing each other. The two fixed blocks 32 are equidistant from the midpoint of the bidirectional lead screw 31, and the openings of the two hooks 2 are opposite each other, resulting in a more balanced weight distribution of the mounting device and more stable flight of the drone after it is mounted on it. The drive assembly 4 is connected to the bidirectional lead screw 31, thereby driving the bidirectional lead screw 31 to rotate.

[0030] Reference Figure 2 The drive assembly 4 includes a motor 41 fixedly connected to the inner wall of the housing 1, a driving bevel gear 42 fixedly connected to the output shaft of the motor 41, and a driven bevel gear 43 sleeved and fixedly connected to the double-acting screw 31. The motor 41 is located on the inner wall of the housing 1 parallel to the double-acting screw 31. The driven bevel gear 43 is coaxial with the double-acting screw 31 and is located in the middle position of the double-acting screw 31, separating the two parts of the double-acting screw 31 by threads. The driving bevel gear 42 meshes with the driven bevel gear 43.

[0031] When the mounting device needs to be attached to the drone, the motor 41 rotates, driving the active bevel gear 42 to rotate. The active bevel gear 42 then drives the driven bevel gear 43 to rotate, which in turn drives the bidirectional lead screw 31 to rotate. The bidirectional lead screw 31 rotates, causing the two fixed blocks 32 to move closer or further apart. The hooks 2 on the two fixed blocks 32 move closer or further apart in the through holes 11 accordingly, thus adjusting the distance between the two hooks 2. This allows the mounting device to be more easily adapted to drones of different models or sizes, enabling the drone to quickly perform transport tasks. Furthermore, the motor 41, active bevel gear 42, and driven bevel gear 43 drive the bidirectional lead screw 31 more conveniently. The forward and reverse rotation of the motor 41 is controllable, allowing the bidirectional lead screw 31 to rotate in either direction, making the distance adjustment between the fixed blocks 32 more convenient.

[0032] Reference Figure 1 Because the bidirectional lead screw 31 rotates under the action of friction, it will cause the hook 2 to rotate. Therefore, in order to make the movement of the hook 2 in the through hole 11 more stable, a limiting block 5 is fixedly connected to each of the two hooks 2. The limiting block 5 is located in the through hole 11. When the fixed block 32 moves, the fixed block 32 will have a tendency to deflect. The limiting block 5 contacts the housing 1 on both sides of the through hole 11. Since the housing 1 on both sides of the through hole 11 blocks the limiting block 5, the fixed block 32 and the hook 2 are not easy to rotate, and the hook 2 moves more stably in the through hole 11.

[0033] Reference Figure 1 and Figure 3 To ensure a more secure attachment of the hooks 2 to the drone and prevent them from detaching, retaining rings 61 are fixedly connected to both hooks 2. The retaining rings 61 are located on the outside of the hooks 2 and at their free ends, i.e., the ends furthest from the limiting block 5. Bolts 62 are threaded through both retaining rings 61. Threaded holes 51 are formed on the upper surfaces of both limiting blocks 5, located below the retaining rings 61. The bolts 62 are threaded into the threaded holes 51. After the hooks 2 are attached to the drone, the operator inserts the bolts 62 into the limiting rings, rotates the bolts 62 to screw them into the threaded holes 51, and tightens them. After tightening, the bolts 62 and hooks 2 form a closed area, making the hooks 2 more securely attached to the drone and preventing them from detaching.

[0034] Reference Figure 1 and Figure 4To facilitate the placement of materials into the cavity of the box 1, an opening is made on the side of the box 1 parallel to the bidirectional lead screw 31 and without the motor 41, i.e., the side opposite to the motor 41. A baffle 7 is hinged to the top of the box 1 on the opening side. The operator can lift the baffle 7, place the materials into the cavity, and then close the baffle 7. The baffle 7 protects and blocks the materials. To make the baffle 7 more stable, buckles 81 are fixedly connected to the two opposite side walls of the baffle 7. Clamping rings 82 are provided on the two outer walls of the box 1 where the bidirectional lead screw 31 is located. A sliding groove 12 is also provided on the outer wall. The clamping rings 82 are U-shaped and can slide within the sliding groove 12, i.e., the clamping rings 82 are slidably connected to the box 1. Since the baffle 7 rotates in a circular motion when closed, it would be inconvenient to engage the buckle 81 into the baffle 82 if the position of the retaining ring 82 were fixed. Therefore, the retaining ring 82 is designed to slide. When the baffle 7 is closed, sliding the retaining ring 82 moves it closer to the buckle 81. At this time, the buckle 81 is horizontal, so the sliding retaining ring 82 can easily engage the buckle 81. When the retaining ring 82 engages the buckle, the retaining ring 82 is located at the outermost edge of the slide groove 12, that is, the end closest to the baffle 7.

[0035] Reference Figure 1 and Figure 4 The buckle 81 includes two hooks 811 and a limiting rod 812. Each hook 811 comprises a rod portion 8111 and a hook portion 8112, with the rod portion 8111 being an elastic element. The limiting rod 812 is located in the middle position, with the two hooks 811 located on either side of it. When the baffle 7 is closed, the operator presses the two hooks 811, bringing them closer together. Then, the retaining ring 82 slides to the rod portion 8111 of the hooks 811, releasing the two hooks 811. The two hooks 811 return to their original position under the elastic force, and the retaining ring 82 blocks the hook portions 8112, thus making the baffle 7 more stable after closing. The limiting rod 812 is used to prevent the two hooks 811 from approaching each other, preventing damage or breakage due to excessive force. Two sets of buckles 81 and retaining rings 82 are provided, located on the two side walls of the baffle 7 respectively. The two sets of buckles 81 and retaining rings 82 make the baffle 7 more secure and stable when closed.

[0036] Reference Figure 1 To prevent damage to the bottom of the container 1 during drone landing and to ensure a more stable landing, four support legs 9 are fixedly connected to the four corners of the bottom of the container 1. The support legs 9 act as a buffer and separate the container 1 from the ground, making it easier for staff to open the baffle 7.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
