[0002] In the field of logistics and distribution, the use of drones for cargo delivery can be flexibly applied to various distribution environments, greatly saving distribution resources and improving distribution efficiency. With the rapid development of drone technology, higher requirements are placed on the types and quantities of cargo carried by drones.

[0003] At present, most of the delivery tasks completed by the automatic delivery system of drones are only the delivery of goods between two points, that is, only one piece of goods can be delivered to a designated destination. Although some drones can carry more goods to multiple destinations, they mostly rely on manual labor to pick up the goods separately after arriving at the corresponding destination. This method of delivery is inefficient and has a high workload. Therefore, designing a multifunctional material frame system that can be used in drones and can carry multiple materials at a time for easy access is a technical problem that corporate R&D personnel urgently need to solve.

[0031] A multi-disc assembly material frame system for a drone of the present application is described below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 4As shown, the UAV multi-disc combined material frame system includes a bearing shaft 1 and a driving mechanism 2. The bearing shaft 1 is connected to the UAV so that the UAV can carry a load. The connection position of the bearing shaft 1 can be the top, the middle or the bottom. The bearing shaft 1 is provided with a plurality of bearing layers 3 along its length direction. Each bearing layer 3 is provided with a plurality of bearing parts 4 along its circumference direction. Each bearing part 4 is provided with a material frame 5 for placing goods and a slider 6. The material frame 5 can adopt a square material frame 5, a circular material frame 5 and a combination of material frames 5 of various shapes according to actual needs. Each material frame 5 is provided with a slide groove 7 for slidingly cooperating with the slider 6 and having openings at both ends. The bearing shaft 1 is provided with a plurality of support plates 8 for supporting the material frame 5 corresponding to the bearing layer 3. The support plates 8 are arranged at intervals between adjacent bearing layers 3. Each support plate 8 is provided with a first notch 9, and the first notch 9 is adapted to the material frame 5. The driving mechanism 2 is used to drive the plurality of bearing layers 3 to rotate respectively. Specifically, the bearing shaft 1 provides a plurality of bearing layers 3 and the bearing parts 4 with a plurality of bearing layers 3. The formed material frame 5 system provides a connection position for stable installation on the drone. The slider 6 equipped on each bearing part 4 is matched with the pallet 8, which can stably place and fix the material frame 5. When the drone passes through the delivery route point, the driving mechanism 2 is started to control the rotation of each bearing layer 3, so that the corresponding bearing layer 3 drives the bearing part 4 where the designated delivery material frame 5 is located to rotate to the first notch 9, and the corresponding next bearing layer 3 drives the slider 6 of the bearing part 4 to rotate to just below the first notch 9. At this time, under the adaptation of the material frame 5 and the first notch 9, the designated material frame 5 can slide to the next bearing layer 3 and cooperate with the slider 6 of the bearing part 4. Repeating the above operation can make the designated material frame 5 detach from the material frame 5 system and slide to the designated receiving position to complete the designated cargo delivery. This process does not require manual intervention, can reduce labor costs and work intensity, can realize automatic, efficient and multi-point delivery of cargo, significantly improve the delivery efficiency of drone logistics, and improve the convenience of material placement in drone logistics.

[0033] The first notches 9 of adjacent support plates 8 are located at the same position, so that the paths of the material frame 5 passing through the support plates 8 are consistent, and there is no need to specify the material frame 5 to discharge materials layer by layer, which can improve the discharge efficiency of the material frame 5 .

[0034] Furthermore, the drone multi-disc combination material frame system also includes a protective shell 10, a lifting rail 11 and a lifting drive 12. The bottom of the protective shell 10 is open, and the inner wall of the protective shell 10 is provided with a limiting rail 13 corresponding to each bearing layer 3 along its own circumference direction. A limiting block 14 is provided on the outside of each material frame 5. The limiting rail 13 and the lifting rail 11 are slidably matched with the limiting block 14. Each limiting rail 13 is provided with a second notch 15, and the second notches 15 of adjacent limiting rails 13 are at the same position. The lifting rail 11 is vertically slidably arranged inside the protective shell 10 and is located between each second notch 15. When any bearing part 4 drives the material frame 5 to rotate to the first notch 9, the limiting block 14 is located at the second notch 15. When the lifting rail 11 is located at any second notch 15, the lifting rail 11 is spliced ​​with the corresponding limiting rail 13 to form a complete Track, the lifting drive 12 is used to drive the lifting track 11 to slide vertically. By setting a protective shell 10, the various components of the feeding frame 5 system are protected, and the material frames 5 of each bearing part 4 can be unloaded from the bottom opening of the protective shell 10, and the material frames 5 are slidably matched with the limiting track 13 through the limiting block 14, which can improve the rotation stability of the bearing part 4. When the material frame 5 needs to slide down, the lifting drive 12 drives the lifting track 11 to the second notch 15 corresponding to the limiting track 13, so that the limiting track 13 and the lifting track 11 are spliced ​​to form a complete track, so that the limiting block 14 can rotate into the lifting track 11, and then the lifting drive 12 drives the lifting track 11 to drive the material frame 5 to slide down, completing the unloading or cooperating with the driving mechanism 2 to enter the limiting track 13 corresponding to any bearing layer 3, completing the flexible loading of the material frame 5.

[0035] Specifically, the lifting drive member 12 is an electric screw, which is arranged inside the protective shell 10 and located on one side of the plurality of second notches 15. The lifting rail 11 is slidably arranged on the electric screw. By adopting the electric screw as the lifting drive member 12, it has the characteristics of compact structure and smooth operation, and can realize precise adjustment of the material frame 5 in the vertical direction.

[0036] In addition, the protective shell 10 is detachably arranged on the load-bearing shaft 1, and the load-bearing shaft 1 is connected to the drone. The detachable connection method facilitates the loading operation of the material frame 5. Specifically, the detachable connection method can adopt threaded connection, assembly connection, etc., which will not be elaborated here.

[0037] In one embodiment, the driving mechanism 2 includes a plurality of fixed gears 21 and a plurality of variable gears 22. The plurality of fixed gears 21 are respectively coaxially arranged between the bearing layer 3 and the bearing shaft 1 corresponding to the plurality of bearing layers 3. A variable shaft 23 is coaxially arranged inside the bearing shaft 1. The variable shaft 23 is slidably connected and self-rotatingly connected to the bearing shaft 1. The plurality of variable gears 22 are coaxially fixedly connected to the variable shaft 23 and correspond to the fixed gears 21 one by one. There is a meshing position on the sliding track of each variable gear 22. When the variable gear 22 is at the meshing position, the variable gear 22 meshes with the corresponding fixed gear 21. The bearing shaft 1 is provided with a meshing position for driving The driving component 24 that moves the variable shaft 23 to slide and drives the variable shaft 23 to rotate is achieved by arranging the variable shaft 23 inside the load-bearing shaft 1, on which a plurality of variable gears 22 are fixed, so that these variable gears 22 are meshed with the fixed gears 21 on the corresponding load-bearing layer 3 when they are in the meshing position. The driving component 24 inside the load-bearing shaft 1 drives the variable shaft 23 to drive the corresponding variable gear 22 to slide to the meshing position and rotate, thereby driving the corresponding load-bearing layer 3 to rotate, thereby realizing independent or synchronous control of multiple load-bearing layers 3, which can improve the space utilization and flexibility of the material frame 5 system, and ensure the efficient and stable operation of the drone material frame 5 system.

[0038] It should be noted that the distance between each shifting gear and the corresponding adjacent fixed gear 21 can be different or partially the same. When different distances are adopted, independent control of each load-bearing layer 3 can be achieved. When partially the same distances are adopted, synchronous control of some load-bearing layers 3 can be achieved. The staff can adjust the distance between each shifting gear and the corresponding adjacent fixed gear 21 according to the actual situation.

[0039] Specifically, in the present embodiment, the variable shaft 23 is a ball guide shaft, the driving assembly 24 includes a rotating motor 241 and a displacement telescopic rod 242, the ball guide shaft is coaxially fixedly connected with a first transmission gear 243, the output shaft of the rotating motor 241 is coaxially fixedly connected with a second transmission gear 244, the first transmission gear 243 is meshed with the second transmission gear 244, a synchronous member 245 is fixedly connected between the telescopic end of the displacement telescopic rod 242 and one end of the ball guide shaft, and by adopting the ball guide shaft as the variable shaft 23, the variable shaft 23 can independently slide and rotate, and the first transmission gear 243 coaxially connected to the ball guide shaft is driven to rotate by the rotating motor 241, and then the ball guide shaft is driven to rotate along the bearing shaft 1 through the meshing second transmission gear 244, the displacement telescopic rod 242 can drive the telescopic end to telescope, so as to drive the ball guide shaft to slide through the synchronous member 245, so as to realize precise control of the independent or synchronous rotation of multiple bearing layers 3.

[0040] It should be noted that the above-mentioned telescopic rod 242 can adopt a conventional electric telescopic rod or a linear motor or other linear drive component that can drive the ball guide shaft to move linearly. The ball guide shaft is a mechanism that uses ball rolling to achieve rotation and sliding motion. Its structure and working principle are common knowledge to technical personnel in this field and will not be elaborated here.

[0041] Preferably, each bearing layer 3 is rotatably connected to the bearing shaft 1 by means of a ball bearing 16. By adopting the ball bearing 16 for rotational connection, the radial and axial loads that the system can withstand can be increased, which is suitable for the working conditions of drone delivery.

[0042] In addition, the drone multi-disc combination material frame system also includes a control system (not shown in the figure) and a power supply module (not shown in the figure). The control system and the power supply module are both arranged on the drone, and the drive mechanism 2 is controlled and connected to the control system and is electrically connected to the power supply module. By setting up a control system and a power supply module integrated in the drone, it is possible to achieve precise control and power supply of the drive mechanism 2, thereby realizing automatic scheduling and unloading of goods in the material frame 5, thereby improving the delivery efficiency of the drone.

[0043] The implementation principle of a multi-disc assembly frame system for a drone in the present application embodiment is as follows: (1) Installing the material frame 5: After removing the protective shell 10, the slide groove 7 of the material frame 5 is matched with the slider 6 of the bearing part 4, and the support plate 8 is loaded to complete the installation of a single material frame 5. Repeat the above operation to complete the installation of the material frame 5 layer by layer. In addition, the protective shell 10 can also be kept intact, and the material frame 5 can be installed starting from the bearing layer 3 at the bottom opening end of the protective shell 10, that is, the material frame 5 enters from the first notch 9 of the bottom support plate 8 while the slide groove 7 of the material frame 5 is matched with the slider 6 of the bearing part 4, and the material frame 5 is automatically transferred into the bearing layer 3 one by one by cooperating with the driving mechanism 2 and the limiting block 14 and the limiting track 13 to complete the installation, and the lifting track 11 and the lifting drive member 12 are cooperated to complete the installation of the material frame 5 layer by layer.

[0044] (2) The UAV arrives at the passing point and unloads the material frame 5: The control system sends information to the driving mechanism 2 and the lifting drive member 12 according to the position of the corresponding material frame 5, so that the driving mechanism 2 drives each bearing layer 3 to drive the bearing part 4 where the designated delivery material frame 5 is located to rotate to the first notch 9, and the lifting drive member 12 drives the lifting rail 11 to slide to the second notch 15 of the corresponding limit rail 13. When the bearing part 4 rotates to the first notch 9, the limit block 14 of the material frame 5 cooperates with the lifting rail 11, and the lifting rail 11 drives the material frame 5 to slide down to the bottom opening end of the protective shell 10, completing the designated cargo delivery.

[0045] It should be noted that a drone multi-disc combination material frame system of the present application can be set up with several systems, which can be connected to drones through several load-bearing shafts 1 to transport more goods. Several drones can also be connected to the load-bearing shafts 1 to cope with situations with larger cargo loads. The present application can also be connected to other flying and mobile equipment through the load-bearing shafts 1 to achieve the function of multi-point cargo delivery.

[0046] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
