Technical Field
[0001] This disclosure relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a cargo delivery system. Background Technology
[0002] To enable cargo transportation via drones, drones are typically equipped with a cargo hold and a gripping mechanism to retrieve the cargo into the cargo hold. In related technologies, the gripping mechanism is complex in structure, occupies a large space, and is detrimental to improving the drone's space utilization and range. Utility Model Content
[0003] The purpose of this disclosure is to provide a cargo transport system to solve the aforementioned technical problems.
[0004] To achieve the above objectives, this disclosure provides a cargo transportation system, including an unmanned aerial vehicle (UAV) and a cargo handover device;
[0005] The drone includes a fuselage and a cargo door. The fuselage has a receiving cavity for accommodating the cargo. The receiving cavity has an opening for the cargo to enter the receiving cavity. The cargo door is movably connected to the fuselage and has a first position exposing the opening and a second position covering the opening. The cargo door is formed as a comb structure and has a plurality of spaced first comb bars. A first groove is provided between adjacent first comb bars.
[0006] The cargo transfer device includes a carrying structure for carrying cargo, the carrying structure being formed as a comb structure and having a plurality of spaced second comb bars, with a second groove between adjacent second comb bars;
[0007] When the cargo door switches between the first position and the second position, the first comb rod passes through the second groove, and the second comb rod passes through the first groove, so that the cargo door can lift the cargo on the carrying structure into the receiving cavity or place the cargo in the receiving cavity onto the carrying structure.
[0008] Optionally, the cargo door is a double-door structure and includes a first cargo door and a second cargo door;
[0009] The first cargo door and the second cargo door switch synchronously between the first position and the second position.
[0010] Optionally, in the second position, the first comb bar on the first cargo door is disposed opposite to the first comb bar on the second cargo door, and the first groove on the first cargo door is disposed opposite to the first groove on the second cargo door.
[0011] Optionally, in the second position, at least a portion of the first comb bar on the first cargo door is located within a first groove on the second cargo door, and at least a portion of the first comb bar on the second cargo door is located within a first groove on the first cargo door.
[0012] Optionally, the drone further includes a pivot and a drive unit. The cargo door is rotatably connected to the fuselage via the pivot, and the drive unit is mounted on the fuselage and connected to the pivot. The drive unit is used to drive the pivot to rotate.
[0013] Optionally, a first partition is provided inside the receiving cavity, which is used to divide the receiving cavity into multiple sub-chambers.
[0014] Optionally, the supporting structure is provided with a second partition, which enables the supporting structure to have multiple cargo placement areas, and the multiple cargo placement areas correspond one-to-one with the multiple sub-chambers.
[0015] Optionally, a stop protrusion is provided at the outer edge of the bearing structure, the stop protrusion being used to stop the goods on the bearing structure.
[0016] Optionally, the cargo transfer device further includes a take-off and landing platform, on which the drone can land;
[0017] The take-off and landing platform is provided with a first positioning structure, which is used by the UAV to identify the take-off and landing platform; and / or, the take-off and landing platform is provided with a second positioning structure, which has a positioning groove and a guiding surface that guides the movement of the UAV.
[0018] Optionally, the cargo handover device further includes a conveying mechanism, and the take-off and landing platform is provided with a cargo handover interface, which is used to provide a channel for cargo handover between the UAV and the carrying structure;
[0019] The conveying mechanism is connected to the carrying structure and is used to convey the carrying structure to the cargo interface.
[0020] Through the above technical solution, the cargo door of the UAV in the cargo conveying system provided in this disclosure can not only open and close the opening of the receiving cavity, but also cooperate with the supporting structure during the closing process to scoop the cargo from the supporting structure into the receiving cavity. Thus, the transfer and transport of cargo between the supporting structure and the UAV can be achieved without a separate cargo gripping mechanism, thereby simplifying the UAV's structure, reducing its production cost, and improving its space utilization. Furthermore, it can also reduce the UAV's weight and increase its flight range.
[0021] Furthermore, since both the cargo door and the load-bearing structure are formed as comb-tooth structures, and during the switching between the first and second positions, the first comb tooth can pass through the second groove on the load-bearing structure, thereby avoiding interference between the cargo door and the load-bearing structure during the loading and unloading of cargo and improving the efficiency of loading and unloading cargo.

Detailed Implementation
[0034] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0035] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are generally defined based on the normal horizontal flight state of the unmanned aerial vehicle (UAV) of the cargo transport system. They are used only for the convenience of describing this disclosure and for simplification, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational construction and operation, and therefore should not be construed as limiting this disclosure. "Inner" and "outer" refer to the inside and outside of the outline of the corresponding component. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0037] like Figures 1 to 8 As shown, this disclosure provides a cargo conveying system 300, including a drone 100 and a cargo transfer device 301. The drone 100 includes a fuselage 1 and a cargo door 2. The fuselage 1 has a receiving cavity 11 for receiving cargo. The receiving cavity 11 has an opening 12 for allowing cargo to enter the receiving cavity 11. The cargo door 2 is movably connected to the fuselage 1 and has a first position exposing the opening 12 and a second position covering the opening 12. The cargo door 2 is formed as a comb structure and has a plurality of spaced first comb bars 21. A first groove 22 is provided between adjacent first comb bars 21.
[0038] The cargo transfer device 301 includes a support structure 200 for carrying cargo. The support structure 200 is formed as a comb structure and has a plurality of spaced second comb bars 201. A second groove 202 is provided between adjacent second comb bars 201.
[0039] When the cargo door 2 switches between the first position and the second position, the first comb rod 21 passes through the second groove 202, and the second comb rod 201 passes through the first groove 22, so that the cargo door 2 can lift the cargo on the carrying structure 200 into the receiving cavity 11 or place the cargo in the receiving cavity 11 onto the carrying structure 200.
[0040] When the drone 100 retrieves cargo from the carrier structure 200 via the aforementioned cargo conveying system 300, the cargo door 2 can first switch from a second position to a first position, positioning the carrier structure 200 and the cargo on it between the cargo door 2 and the fuselage 1. Then, the cargo door 2 can switch from the first position to the second position. During this switching process, the first comb bar 21 of the cargo door 2 can penetrate into the second groove 202 of the carrier structure 200, extending to the bottom of the cargo to lift it and load it into the receiving cavity 11 of the fuselage 1. When the cargo door 2 is in the second position, the cargo is supported by the cargo door 2.
[0041] When the drone 100, which uses the aforementioned cargo conveying system 300, places cargo onto the carrier structure 200, the drone 100 can approach the carrier structure 200, and the cargo door 2 can switch from the second position to the first position. During the switching process, the cargo is gradually transferred onto the carrier structure 200. After the cargo door 2 places the cargo onto the carrier structure 200, the first comb rod 21 can pass through the second groove 202 of the carrier structure 200, thereby completely separating from the cargo. After the drone 100 takes off again, the cargo door 2 can switch from the first position to the second position, closing the opening 12.
[0042] Through the above technical solution, the cargo door 2 of the drone 100 in the cargo conveying system 300 provided in this disclosure can not only open and close the opening 12 of the receiving cavity 11, but also cooperate with the supporting structure 200 during the closing of the opening 12 to lift the cargo from the supporting structure 200 into the receiving cavity 11, and place the cargo onto the supporting structure 200 during the opening 12. Thus, the transfer and transport of cargo between the supporting structure 200 and the drone 100 can be achieved without setting up a separate cargo gripping mechanism, thereby simplifying the structure of the drone 100, reducing the production cost of the drone 100, and improving the space utilization rate of the drone 100. Furthermore, it can also reduce the weight of the drone 100 and increase its flight range.
[0043] Furthermore, since both the cargo door 2 and the load-bearing structure 200 are formed as comb-tooth structures, and during the switching between the first position and the second position, the first comb tooth 21 can pass through the second groove 202 on the load-bearing structure 200, and the second comb tooth 201 on the load-bearing structure 200 can pass through the first groove 22 on the cargo door 2, thereby avoiding interference between the cargo door 2 and the load-bearing structure 200 during the loading and unloading of goods, and improving the efficiency of loading and unloading goods.
[0044] This disclosure does not limit the specific number or connection method of the cargo door 2. In one embodiment provided in this disclosure, such as Figure 2 , Figure 3 and Figure 4 As shown, the cargo door 2 is a double-door structure and includes a first cargo door 23 and a second cargo door 24. The first cargo door 23 and the second cargo door 24 switch synchronously between a first position and a second position.
[0045] The first cargo door 23 is movably connected to the fuselage 1 on the side away from the second cargo door 24. The first comb bar 21 and the first groove 22 on the first cargo door 23 are located on the side of the first cargo door 23 closest to the second cargo door 24. The second cargo door 24 is movably connected to the fuselage 1 on the side away from the first cargo door 23. The first comb bar 21 and the first groove 22 on the second cargo door 24 are located on the side of the second cargo door 24 closest to the first cargo door 23.
[0046] When the first cargo door 23 and the second cargo door 24, which are configured to open in opposite directions, are in the first position, they can be moved away from the opening 12 of the receiving cavity 11 and together with the fuselage 1 to form a receiving space, so that the carrying structure 200 and the cargo can be located within the receiving space. When the first cargo door 23 and the second cargo door 24 switch between the first position and the second position, the first cargo door 23 and the second cargo door 24 switch synchronously, so that the first comb bar 21 and the first groove 22 of the first cargo door 23 and the second cargo door 24 can respectively pass through the second groove 202 of the corresponding part of the carrying structure 200 and the first cargo door 23 and the second cargo door 24, thereby increasing the contact area between the cargo door 2 and the cargo and reducing the probability of the cargo falling off during the grabbing process.
[0047] Optionally, such as Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, in the second position, the first comb bar 21 on the first cargo door 23 is disposed opposite to the first comb bar 21 on the second cargo door 24, and the first groove 22 on the first cargo door 23 is disposed opposite to the first groove 22 on the second cargo door 24. The opposite arrangement of the first comb bar 21 on the first cargo door 23 and the first comb bar 21 on the second cargo door 24 avoids the problem of mutual friction and interference between the first comb bar 21 on the first cargo door 23 and the first comb bar 21 on the second cargo door 24 when switching between the first and second positions.
[0048] In another embodiment, in the second position, at least a portion of the first comb bar 21 on the first cargo door 23 is located within the first groove 22 on the second cargo door 24, and at least a portion of the first comb bar 21 on the second cargo door 24 is located within the first groove 22 on the first cargo door 23. That is, the first cargo door 23 and the first comb bar 21, and the first comb bar 21 of the second cargo door 24 are arranged alternately. The alternating first comb bars 21 enable the opening 12 to be covered and closed as much as possible when the first cargo door 23 and the second cargo door 24 are in the second position, ensuring the safety of the cargo located in the receiving cavity 11.
[0049] This disclosure does not limit the connection method between the cargo door 2 and the fuselage 1. The cargo door 2 can be rotatably connected to the fuselage 1 or movablely connected to the fuselage 1. In one embodiment provided in this disclosure, such as Figure 4 As shown, the UAV 100 also includes a pivot 3 and a drive unit. The cargo door 2 is rotatably connected to the fuselage 1 via the pivot 3. The drive unit is installed on the fuselage 1 and is connected to the pivot 3 for transmission. The drive unit is used to drive the pivot 3 to rotate.
[0050] It is understood that in embodiments where the cargo door 2 includes a first cargo door 23 and a second cargo door 24, one side of the first cargo door 23 and one side of the second cargo door 24 are rotatably connected to the fuselage 1 via a pivot 3. Multiple drive components can be used, and each pivot 3 has a corresponding drive component. The drive component drives its corresponding pivot 3 to rotate, thereby causing the first cargo door 23 and the second cargo door 24 to rotate.
[0051] Alternatively, there may be a single drive unit. The drive unit is connected to the rotating shaft 3 of the first cargo door 23 and the rotating shaft 3 of the second cargo door 24 via a transmission assembly. The driving force of the drive unit can drive the rotating shaft 3 of the first cargo door 23 and the rotating shaft 3 of the second cargo door 24 to rotate through the transmission assembly, thereby driving the first cargo door 23 and the second cargo door 24 to rotate.
[0052] Optionally, the driving component can be a motor. The transmission assembly may include a transmission rod and a gear set. The motor is connected to the transmission rod, and both ends of the transmission rod are connected to the rotating shaft 3 via the gear set, thereby driving the rotating shaft 3 to rotate.
[0053] In another embodiment provided in this disclosure, the drone 100 may include a telescopic member for driving the cargo door 2 to move up and down. When the cargo door 2 is in a first position away from the opening 12, a receiving space is formed between the fuselage 1 and the cargo door 2. The carrying structure 200 and the cargo can enter or exit the receiving space from the open ends at both ends along the length direction of the fuselage 1, or from the open end on one side along the width direction of the fuselage 1. When the cargo door 2 moves from the first position to the second position, the cargo door 2, which is formed with a comb-like structure, passes through the carrying structure 200, thereby lifting the cargo into the receiving space 11.
[0054] Optionally, the fuselage 1 is provided with a mounting cavity communicating with the receiving cavity 11, and the drive unit can be located inside the mounting cavity. The mounting cavity can prevent the drive unit from occupying the volume of the receiving cavity 11, so that the receiving cavity 11 can load more goods.
[0055] Optionally, such as Figure 5 As shown, a first partition 13 is provided inside the receiving cavity 11, which divides the receiving cavity 11 into multiple sub-cavities 111. Since the size and type of goods vary, the multiple sub-cavities 111 can be classified according to the size and type of the goods to be loaded; that is, different goods can be loaded in different cavities, thereby making full use of the space of the receiving cavity 11 and loading more goods. Furthermore, the sub-cavities 111 can also confine the goods between the inner walls of the sub-cavities 111, preventing the goods from shaking and thus ensuring the safety and integrity of the goods during transportation.
[0056] This disclosure does not limit the number or extension direction of the first partition 13. The number of the first partition 13 can be one or more. The first partition 13 can extend along the length direction of the fuselage 1, or along the width direction of the fuselage 1, or along any other horizontal direction, as long as it can divide the receiving cavity 11 into multiple sub-cavities 111.
[0057] Optionally, such as Figure 7 As shown, a stop protrusion 203 is provided at the outer edge of the support structure 200. The stop protrusion 203 is used to stop the goods on the support structure 200. Providing the stop protrusion 203 at the outer edge of the support structure 200 can prevent the goods from falling off the support structure 200 when the drone 100 places the goods on the support structure 200, thus ensuring the safety and integrity of the goods.
[0058] Optionally, such as Figure 7As shown, each end of the second comb bar 201 is provided with a stop protrusion 203. The ends and sides of the two second comb bars 201 located at both ends are provided with stop protrusions 203, so that they are arranged together with the stop protrusions 203 at the ends of the other second comb bars 201 to surround the bearing surface of the bearing structure 200.
[0059] Optionally, such as Figure 5 and Figure 7 As shown, a second partition 204 is provided on the supporting structure 200, which enables the supporting structure 200 to have multiple cargo placement areas, and the multiple cargo placement areas correspond one-to-one with multiple sub-chambers 111.
[0060] The support structure 200 is divided into multiple cargo placement areas corresponding to the sub-chambers 111 by a second partition 204. This allows different goods located in different sub-chambers 111 to be placed in different cargo placement areas after being placed on the support structure 200 by the drone 100, making it easier to distinguish between different goods. Similarly, when the drone 100 retrieves goods from the support structure 200, goods located in different cargo placement areas can enter different sub-chambers 111.
[0061] Optionally, such as Figure 7 As shown, the supporting structure 200 may also include a main body 205, with a plurality of second comb bars 201 and second grooves 202 on both opposite sides of the main body 205, and a second partition 204 disposed on the main body 205.
[0062] To facilitate the stable transfer of goods between the drone 100 and the load-bearing structure 200, optionally, such as Figure 5 and Figure 7 As shown, the cargo transfer device 301 also includes a take-off and landing platform 302, on which the drone 100 can dock to transfer cargo with the carrying structure 200.
[0063] To facilitate the precise positioning of the UAV 100 on the take-off and landing platform 302, a first positioning structure 303 may be provided on the take-off and landing platform 302. The first positioning structure 303 is used by the UAV 100 to identify the take-off and landing platform 302; and / or, a second positioning structure 304 may also be provided on the take-off and landing platform 302. The second positioning structure 304 has a positioning groove 305, and the positioning groove 305 has a guiding surface 306 for guiding the movement of the UAV 100.
[0064] When the drone 100 lands, it can first identify the take-off and landing platform 302 through the first positioning structure 303, obtain the position of the take-off and landing platform 302, and then approach the take-off and landing platform 302. After the drone approaches the take-off and landing platform 302, it can be guided to the position to hand over the goods to the carrying structure 200 through the positioning slot 305 on the second positioning structure 304.
[0065] This disclosure does not limit the specific structure of the second positioning structure 304, and the positioning groove 305 can be of any shape, such as a U-shaped groove, a V-shaped groove, or a rectangular groove, for example. Figure 8 As shown, in one embodiment provided in this disclosure, the positioning groove 305 can be a V-shaped groove, and the two side walls of the V-shaped groove are constructed as guide surfaces 306. The bottom of the fuselage 1 of the UAV 100 is also provided with a positioning mating part 14 corresponding to the positioning groove 305. The positioning mating part 14 can contact the guide surface 306 of the V-shaped groove during the landing of the UAV 100, and thus be supported by the bottom of the V-shaped groove under the guidance of the guide surface 306.
[0066] Optionally, such as Figure 6 As shown, there can be multiple positioning slots 305, and the bottom of the fuselage 1 of the UAV 100 can also be provided with multiple positioning mating parts 14 corresponding to the positioning slots 305. The multiple positioning slots 305 are disposed on the take-off and landing platform 302, and the multiple positioning mating parts 14 are disposed on the fuselage 1 of the UAV 100, corresponding to the multiple positioning slots 305. The multiple positioning slots 305 and positioning mating parts 14 can increase the accuracy of positioning when the UAV 100 lands, and improve the positioning efficiency of the UAV 100.
[0067] This disclosure does not limit the specific type of the first positioning structure 303, as long as the first positioning structure 303 can enable the drone 100 to identify the position of the take-off and landing platform 302. For example, the first positioning structure 303 can be a positioning code set on the take-off and landing platform 302, which can be used in conjunction with the camera of the drone 100; or, the first positioning structure 303 can be a Wi-Fi access point or a Bluetooth beacon, which can be used in conjunction with the wireless signal on the drone 100.
[0068] In the embodiment where the first positioning structure 303 is a positioning code set on the landing platform 302, and the positioning groove 305 of the second positioning structure 304 has a guide surface 306, and the bottom of the fuselage 1 of the UAV 100 has a positioning mating part 14 that cooperates with the positioning groove 305, when the UAV 100 lands, the UAV 100 can first identify the position of the landing platform 302 by recognizing the positioning code on the landing platform 302, and then move closer to the landing platform 302. After the UAV 100 approaches the landing platform 302, the guide surface 306 in the positioning groove 305 can cooperate with the positioning mating part 14 of the UAV 100 to guide the UAV 100 to a specific position, achieving precise physical positioning of the UAV 100. Finally, the UAV 100 stops above the support structure 200 so that it can transfer cargo with the support structure 200 located below the fuselage 1.
[0069] To improve the transportation efficiency of the freight transportation system, optionally, such as Figure 6 and Figure 8 As shown, the cargo transfer device 301 also includes a conveying mechanism 307. The take-off and landing platform 302 is provided with a cargo transfer interface. The cargo transfer interface is used to provide a channel for cargo transfer between the UAV 100 and the carrier structure 200. The conveying mechanism 307 is connected to the carrier structure 200 and is used to convey the carrier structure 200 to the cargo transfer interface.
[0070] Users can place goods on the carrying structure 200. Since the conveying mechanism 307 is connected to the carrying structure 200, the conveying mechanism 307 can convey the carrying structure 200 carrying goods to the cargo interface of the take-off and landing platform 302 for the drone 100 to pick up the goods. The conveying mechanism 307 can also convey the goods delivered by the drone 100 to the carrying structure 200 to the user to complete the delivery of the goods.
[0071] This disclosure does not limit the specific structure of the conveying mechanism 307. The conveying mechanism 307 may include a conveyor 310 and a drive component. The support structure 200 is placed on the conveyor 310. The conveyor 310 can move between the user and the cargo interface of the lifting platform 302 under the drive of the drive component.
[0072] The drive assembly may include a drive component, a lifting rod, and a drive nut. The conveyor table 310 is mounted on the lifting rod and can move vertically along with the lifting rod. The lifting rod can be a screw rod, and the drive nut is threadedly connected to the screw rod to form a screw-nut pair. The drive component is drively connected to the drive nut so that the drive nut rotates, driving the lifting rod to move.
[0073] Optionally, multiple cargo transfer devices 301 can be placed within a certain area to increase the number of take-off and landing platforms 302, so that multiple drones 100 can take off and land and transfer cargo with the carrying structure 200, thereby meeting the transportation capacity needs of the area.
[0074] In another embodiment provided in this disclosure, there may be multiple conveyor platforms 310, and the drive assembly may also include a drive member, a transmission chain and a drive wheel. Multiple conveyor platforms 310 are spaced apart on the transmission chain. The output end of the drive member is connected to the drive wheel. The transmission chain is sleeved on the drive wheel. The conveyor platform 310 can move under the drive of the transmission chain, thereby driving the load-bearing structure 200 and the goods located on the conveyor platform 310 to move, forming a cyclic conveying mechanism 307.
[0075] Optionally, such as Figure 6 and Figure 8 As shown, the take-off and landing platform 302 may also include a platform body 308 and a support 309. The platform body 308 is mounted on top of the support 309 for the drone 100 to land on. A cargo interface is located on the platform body 308, and a conveying mechanism 307 can be mounted on the support 309.
