Description

Technical Field

[0001] The present invention relates to the technical field of drone delivery, and in particular to a drone multi-point delivery cabin system. Background Art

[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. However, most of the current delivery tasks completed by drone automatic delivery systems are only cargo delivery between two points, that is, only one piece of cargo can be delivered to a designated destination. Although some drones can carry more cargo to multiple destinations, they mostly rely on manual labor to pick up the cargo separately after arriving at the corresponding destination. This method of delivery has low efficiency and high work intensity. Therefore, designing a drone multi-point distribution cargo compartment system that can automatically deliver different cargo to different destinations is a technical problem that corporate R&D personnel urgently need to solve. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides a drone multi-point delivery cabin system.

[0004] The above invention objectives of the present application are achieved through the following technical solutions: A central connecting shaft, the central connecting shaft is connected to the drone, the central connecting shaft is provided with a plurality of storage layers along its length direction, each of the storage layers is provided with a plurality of storage parts along its circumference direction, each of the storage parts is provided with a cargo hold for placing cargo and is vertically provided with a slideway groove with both ends open, and each of the cargo holds is provided with a slider for slidingly cooperating with the slideway groove; At least one of the storage parts in each storage layer is a material passing part, and there is a material passing position on the rotation track of the material passing part. When the material passing part is at the material passing position, the corresponding slide groove and all the slide grooves below the material passing part are connected to form at least one temporary material discharge channel; A driving mechanism is used to drive the plurality of storage layers to rotate respectively.

[0005] By adopting the above technical solution, the central connecting shaft provides a connection position for the cargo hold storage structure formed between several storage layers and storage parts to be firmly installed on the drone. When the drone passes through the delivery route, the driving mechanism is started to control the rotation of each storage layer, so that the material passing part of each storage layer and the storage part where the designated delivery cargo hold is located are rotated to the material passing position. At this time, the slide groove of the material passing part and its downward slide groove are connected to form a temporary material discharge channel, allowing the slider located on the material discharge channel to drive the cargo hold to slide down to the designated receiving position under its own gravity to complete the designated cargo delivery. In this process, no human intervention is required, and automatic, efficient and multi-point delivery of cargo in the cargo hold is realized, which can significantly improve the delivery efficiency of drone logistics, enhance the flexibility and accuracy of drone delivery, and reduce labor costs and work intensity.

[0006] In a preferred example, the present application can be further configured as follows: the drone multi-point delivery cabin system also includes a locking mechanism, which is used to close the bottom opening end of the slide groove, and when the material passing part is in the material passing position, the locking mechanism is used to open the bottom opening end of the slide groove.

After a temporary unloading channel is formed, it is automatically unlocked through the locking mechanism, which can enable the slider located on the unloading channel to drive the cargo hold to slide to the designated receiving position under the action of its own gravity, thereby completing the designated cargo delivery.

When the UAV reaches the designated position and the material passing part rotates to the material passing position, the limiting telescopic rod is extended to abut the connecting rod. At this time, the baffle rod retreats into the installation groove under the reaction force of the rotational power to open the open end at the bottom of the slide groove and realize automatic delivery of the cargo hold.

[0011] By adopting the above technical solution, the connecting rod is set in the strip sliding hole, which can ensure that it abuts against the limiting telescopic rod while limiting the sliding path of the blocking rod in the installation groove, thereby preventing the blocking rod from detaching from the installation groove and improving the safety of cargo transportation in the cargo hold.

[0012] In a preferred example, the present application can be further configured as follows: the elastic member is a spring, and the spring is fixedly connected between the blocking rod and the bottom wall of the installation groove.

[0013] By adopting the above technical solution, the spring can continuously provide elastic restoring force to the blocking rod through elastic deformation, so as to continuously push the blocking rod to move closer to the bottom opening end of the slideway groove.

[0016] In a preferred example, the present application can be further configured as follows: the driving mechanism includes a plurality of fixed gears and a plurality of variable gears, the plurality of fixed gears are respectively coaxially arranged between the storage layer and the central connecting shaft corresponding to the plurality of storage layers, a variable shaft is coaxially arranged inside the central connecting shaft, the variable shaft is slidably connected and self-rotatingly connected to the central connecting shaft, a plurality of variable gears are coaxially fixedly connected to the variable shaft and correspond one-to-one to the fixed gears, each of the variable gears has a meshing position on its sliding trajectory, when the variable gear is located at the meshing position, the variable gear meshes with the corresponding fixed gear, and a driving component for driving the variable shaft to slide and drive the variable shaft to rotate is arranged inside the central connecting shaft.

[0017] By adopting the above technical solution, a variable shaft is arranged inside the central connecting shaft, on which a number of variable gears are fixed, so that these variable gears mesh with the fixed gears on the corresponding storage layers when in the meshing position, and the variable shaft is driven by the driving assembly inside the central connecting shaft to drive the corresponding variable gears to slide to the meshing position and rotate, thereby driving the corresponding storage layer to rotate, thereby realizing independent or synchronous control of multiple storage layers, which can improve the space utilization and flexibility of the cargo hold system, and ensure the efficient and stable operation of the drone multi-point distribution cargo hold system.

[0018] In a preferred example, the present application can be further configured as follows: the variable shaft is a ball guide shaft, the drive assembly includes a rotating motor and a shifting telescopic rod, the ball guide shaft is coaxially fixedly connected with a first transmission gear, the output shaft of the rotating motor is coaxially fixedly connected with a second transmission gear, the first transmission gear is meshed with the second transmission gear, and a synchronization member is fixedly connected between the telescopic end of the shifting telescopic rod and one end of the ball guide shaft.

[0019] By adopting the above technical solution and using a ball guide shaft as a variable shaft, the variable shaft can independently slide and rotate, and the first transmission gear coaxially connected to the ball guide shaft is driven to rotate by a rotating motor, and then the ball guide shaft is driven to rotate along the central connecting axis through the meshing second transmission gear. The displacement telescopic rod can drive the telescopic end to extend and retract, so as to drive the ball guide shaft to slide through the synchronization member, thereby realizing precise control of the independent or synchronous rotation of multiple storage layers.

[0020] In a preferred example, the present application can be further configured as follows: each of the storage layers is rotatably connected to the central connecting shaft by means of a ball bearing.

[0021] By adopting the above technical solution and using ball bearings for rotational connection, the radial and axial loads that the system can withstand can be increased, making it suitable for drone delivery conditions.

The detachable connection method is used to facilitate the loading operation of the cargo hold, and the central connecting shaft is connected to the drone to complete the load of the drone.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

When the drone passes through the delivery route, the driving mechanism is started to control the rotation of each storage layer, so that the material passing part of each storage layer and the storage part where the designated delivery cargo hold are located are rotated to the material passing position. At this time, the slide groove of the material passing part and its downward slide groove are connected to form a temporary material discharge channel, allowing the slider located on the material discharge channel to drive the cargo hold to slide down to the designated receiving position under its own gravity to complete the designated cargo delivery.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0034] The following describes a drone multi-point delivery cabin system of the present application with reference to the accompanying drawings.

[0035] Reference Figures 1 to 4, among which, Figure 1 As shown, the drone multi-point distribution cargo hold system includes a central connecting shaft 1 and a driving mechanism 3. The central connecting shaft 1 is provided with a plurality of storage layers 4 along its length direction. Each storage layer 4 is provided with a plurality of storage parts 5 along its circumference direction. Each storage part 5 is provided with a cargo hold 6 for placing cargo and is vertically provided with a slideway groove 7 with both ends open. The cargo hold 6 can adopt a square cargo hold 6, a circular cargo hold 6 and a combination of cargo holds 6 of various shapes according to actual needs. Each cargo hold 6 is provided with a slider 8 for slidingly cooperating with the slideway groove 7. At least one storage part 5 in each storage layer 4 is a material passing part 9. There is a material passing position on the rotation trajectory of the material passing part 9. When the material passing part 9 is at the material passing position, the corresponding slideway groove (7) and all the slideway grooves (7) below the material passing part (9) are connected to form at least one temporary material unloading channel. The driving mechanism 3 is used to drive the plurality of storage parts 5 to pass through the material passing part 9. The layer 4 rotates, wherein the central connecting shaft 1 provides a connection position for the cargo hold 6 storage structure formed between several storage layers 4 and the storage part 5 to be firmly installed to the drone. When the drone passes the delivery route, the driving mechanism 3 is started to control the rotation of each storage layer 4, so that the material passing part 9 of each storage layer 4 and the storage part 5 where the designated delivery cargo hold 6 is located rotate to the material passing position. At this time, the slide groove 7 of the material passing part 9 and its downward slide groove 7 are connected to form a temporary material discharge channel, allowing the slider 8 located on the material discharge channel to drive the cargo hold 6 to slide down to the designated receiving position under its own gravity to complete the designated cargo delivery. In this process, no human intervention is required, and the automatic, efficient and multi-point delivery of the cargo in the cargo hold 6 is realized, which can significantly improve the delivery efficiency of drone logistics, enhance the flexibility and accuracy of drone delivery, and reduce labor costs and work intensity.

[0036] Furthermore, the drone multi-point delivery cargo hold system also includes a locking mechanism 2, which is used to close the bottom open end of the slide groove 7, and when the material passing part 9 is in the material passing position, the locking mechanism 2 is used to open the bottom open end of the slide groove 7. The slide groove 7 equipped in each storage part 5 is matched with a locking structure, which can stably place and fix the cargo hold 6, and can play a role in bearing the cargo hold 6. After a temporary unloading channel is formed, it is automatically unlocked through the locking mechanism 2, which can enable the slider 8 located on the unloading channel to drive the cargo hold 6 to slide to the designated receiving position under the action of its own gravity, thereby completing the designated cargo delivery.

[0037] It should be noted that any storage section 5 can be used as a material passing section 9 after rotating the storage layer 4, and when the slide groove 7 of any material passing section 9 is connected, the position of the material passing section 9 is the material passing position, and the slide groove 7 of any upper and lower adjacent storage sections 5 can be used as a temporary material unloading channel. In actual operation, except for the highest first-floor storage layer 4, any storage section 5 can be vacated on each storage layer 4 as an alternative to the material passing section 9, so that the goods in each cargo hold 6 can be unloaded smoothly, and the storage sections 5 of each storage layer 4 can be staggered by staggered settings, and the driving mechanism 3 can be used to drive each storage layer 4 to rotate to make way for the cargo hold 6 on the designated delivery storage section 5, and then the locking mechanism 2 can be unlocked, so that the cargo hold 6 on each storage section 5 can be unloaded directly through the slide groove 7.

[0038] In one embodiment, if Figure 2 and Figure 3 As shown, the locking mechanism 2 includes a plurality of mounting seats 21, each mounting seat 21 is correspondingly arranged at the bottom of the storage portion 5, the mounting seat 21 is provided with a mounting groove 22, an elastic member and a blocking rod 23 are arranged in the mounting groove 22, the blocking rod 23 is slidably arranged in the mounting groove 22 and is located at the bottom open end of the slideway groove 7, the elastic member is used to provide the blocking rod 23 with a thrust to move close to the bottom open end of the slideway groove 7, the blocking rod 23 is extended with a connecting rod 24, and the central connecting shaft 1 is provided with a limited telescopic rod 25. When the material passing portion 9 is in the material passing position, the limited telescopic rod 25 The retractable rod 25 is used to extend to the connecting rod 24 to abut against the connecting rod 24. During operation, the normal blocking rod 23 is located at the bottom open end of the slide groove 7 under the action of the elastic member to close the slide groove 7 and prevent the cargo hold 6 from slipping. When the UAV reaches the specified position and the material passing part 9 rotates to the material passing position, the limiting telescopic rod 25 extends to abut against the connecting rod 24. At this time, the blocking rod 23 retreats into the installation groove 22 under the reaction force of the rotational power to open the open end at the bottom of the slide groove 7 and realize the automatic delivery of the cargo hold 6.

[0039] Specifically, the elastic member is a spring 26, which is fixedly connected between the blocking rod 23 and the inner bottom wall of the mounting groove 22. The spring 26 can continuously provide elastic restoring force to the blocking rod 23 through elastic deformation, so as to continuously push the blocking rod 23 to move closer to the bottom opening end of the slide groove 7.

[0040] Furthermore, a strip sliding hole 27 is opened at the bottom of the mounting seat 21 along the length direction of the mounting groove 22, and the strip sliding hole 27 is connected to the mounting groove 22. The connecting rod 24 is slidably set inside the strip sliding hole 27 and extends out of the strip sliding hole 27. By setting the connecting rod 24 in the strip sliding hole 27, it can ensure that it abuts against the limiting telescopic rod 25 while limiting the sliding path of the blocking rod 23 in the mounting groove 22, thereby preventing the blocking rod from detaching from the mounting groove 22, thereby improving the safety of cargo transportation in the cargo hold 6.

[0041] In addition, in order to prevent the storage layer 4 from rotating by itself when the drone is performing a delivery task, a number of positioning marbles 10 are provided on the central connecting shaft 1 corresponding to the storage layer 4. The positioning marbles 10 are precision components that use the elastic force of a spring 26 to drive the ball to move and reset to achieve a positioning function. A number of positioning grooves 11 that are compatible with the shape and size of the positioning marbles 10 are opened at the bottom of each storage layer 4. There is a fixed position on the rotation trajectory of the storage layer 4. When the storage layer 4 rotates to the fixed position, the positioning marbles 10 are plugged into and matched with the positioning grooves 11. When the drone is performing a delivery task, the plug-in cooperation of the positioning marbles 10 and the positioning grooves 11 can improve the stability of the storage layer 4 when no rotation is required for loading and unloading. When rotation is required, the storage layer 4 is driven to rotate by the driving mechanism 3, and the positioning marbles 10 can be disengaged from the positioning grooves 11 that are compatible with the shape and size and rotate, so as to provide convenience for the cargo hold 6 system, which is suitable for this working condition.

[0042] In one embodiment, if Figure 1 and Figure 4 As shown, the driving mechanism 3 includes a plurality of fixed gears 31 and a plurality of variable gears 32. The plurality of fixed gears 31 are respectively coaxially arranged between the storage layer 4 and the central connecting shaft 1 corresponding to the plurality of storage layers 4. A variable shaft 33 is coaxially arranged inside the central connecting shaft 1. The variable shaft 33 is slidably connected and self-rotatingly connected to the central connecting shaft 1. The plurality of variable gears 32 are coaxially fixedly connected to the variable shaft 33 and correspond to the fixed gears 31 one by one. There is a meshing position on the sliding track of each variable gear 32. When the variable gear 32 is in the meshing position, the variable gear 32 meshes with the corresponding fixed gear 31. The central connecting shaft 1 is provided with a meshing position for driving The variable shaft 33 slides and the driving component 34 drives the variable shaft 33 to rotate. By setting the variable shaft 33 inside the central connecting shaft 1, a plurality of variable gears 32 are fixed on it, so that these variable gears 32 are meshed with each other when they are in the meshing position with the fixed gears 31 on the corresponding storage layer 4. The driving component 34 inside the central connecting shaft 1 drives the variable shaft 33 to drive the corresponding variable gear 32 to slide to the meshing position and rotate, thereby driving the corresponding storage layer 4 to rotate, realizing independent or synchronous control of multiple storage layers 4, which can improve the space utilization and flexibility of the cargo hold 6 system, and ensure the efficient and stable operation of the drone multi-point distribution cargo hold system.

[0043] It should be noted that the distance between each shifting gear and the corresponding adjacent fixed gear 31 can be different or partially the same. When different distances are adopted, independent control of each storage layer 4 can be achieved. When partially the same distances are adopted, synchronous control of some storage layers 4 can be achieved. The staff can adjust the distance between each shifting gear and the corresponding adjacent fixed gear 31 according to the actual situation.

[0044] Specifically, the variable shaft 33 is a ball guide shaft, and the driving assembly 34 includes a rotating motor 341 and a shifting telescopic rod 342. The ball guide shaft is coaxially fixedly connected with a first transmission gear 343, and the output shaft of the rotating motor 341 is coaxially fixedly connected with a second transmission gear 344. The first transmission gear 343 is meshed with the second transmission gear 344. A synchronous member 345 is fixedly connected between the telescopic end of the shifting telescopic rod 342 and one end of the ball guide shaft. By adopting the ball guide shaft as the variable shaft 33, the variable shaft 33 can independently slide and rotate, and the first transmission gear 343 coaxially connected to the ball guide shaft is driven to rotate by the rotating motor 341, and then the ball guide shaft is driven to rotate along the central connecting axis 1 through the meshing second transmission gear 344. The shifting telescopic rod 342 can drive the telescopic end to extend and retract, so as to drive the ball guide shaft to slide through the synchronous member 345, so as to realize precise control of the independent or synchronous rotation of multiple storage layers 4.

[0045] It should be noted that the above-mentioned limiting telescopic rod 25 and the shifting telescopic rod 342 can both adopt conventional electric telescopic rods or linear motors and other linear drive parts 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.

[0046] Preferably, each storage layer 4 is rotatably connected to the central connecting shaft 1 by means of a ball bearing 12. By adopting the ball bearing 12 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.

[0047] In addition, the drone multi-point delivery cargo hold system also includes a control system and a power supply module (not shown in the figure). The control system and the power supply module are both arranged on the drone. The locking mechanism 2 and the driving mechanism 3 are both controlled and connected to the control system and are 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 locking mechanism 2 and the driving mechanism 3, thereby realizing automatic scheduling and unloading of goods in the cargo hold 6, thereby improving the delivery efficiency of the drone.

[0048] Preferably, in order to protect the cargo hold 6 system, the drone multi-point distribution cargo hold system also includes a protective shell (not shown in the figure), which is detachably arranged on the central connecting shaft 1 and has an opening at the bottom. By setting the protective shell, protection is provided for the various components of the cargo hold 6 system, and the cargo holds 6 of each storage section 5 can be unloaded from the bottom opening of the protective shell, and the loading operation of the cargo hold 6 is facilitated by a detachable connection method. The central connecting shaft 1 is connected to a drone (not shown in the figure) to facilitate the drone to carry the cargo hold 6. The connection position of the central connecting shaft 1 can be the top, middle or bottom.

[0049] The implementation principle of the drone multi-point delivery cabin system in the present application embodiment is as follows: (1) Installing the cargo hold 6: The bottom opening end of the slide groove 7 of the storage part 5 of the bottom storage layer 4 is closed by the locking mechanism 2, and the bottom opening ends of the remaining slide grooves 7 are opened, so that the cargo hold 6 starts from the first storage layer 4 at the top of the central connecting shaft 1, and the slider 8 of the cargo hold 6 is matched with the slide groove 7 of the storage part 5 to make the cargo hold 6 slide to the storage part 5 of the bottom storage layer 4, and then the storage layer 4 is driven to rotate by the driving mechanism 3, so that the slide groove 7 of the adjacent storage part 5 is connected to the slide groove 7 of the upper storage part 5, and the material is continuously unloaded until the bottom storage layer 4 is full, and the bottom opening end of the slide groove 7 of the storage part 5 of the adjacent upper storage layer 4 is closed by the locking mechanism 2, and the material loading work is continued in this way.

[0050] (2) The UAV arrives at the waypoint and unloads the cargo hold 6: The control system sends information to the driving mechanism 3 and the locking mechanism 2 according to the position of the corresponding cargo hold 6, so that the driving mechanism 3 drives the material passing parts 9 of each storage layer 4 and the storage part 5 where the designated cargo hold 6 is located to rotate to the material passing position. When the storage part 5 rotates to the material passing position, the locking mechanism 2 is unlocked, so that the cargo hold 6 can be separated from the cargo hold 6 system through the temporarily formed unloading channel and slide to the designated receiving position, thereby completing the designated cargo delivery.

[0051] It should be noted that a drone multi-point delivery cargo cabin system of the present application can be set up with several, connected to drones through several central connecting shafts to transport more goods, and several drones can also be connected to the central connecting shaft to cope with situations with larger cargo loads, and the present application can also be connected to other flying and mobile equipment through the central connecting shaft to achieve the function of multi-point cargo delivery.

[0052] 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.
