Description

Technical Field

[0001] This invention belongs to the technical field of low-altitude logistics technology, specifically a smart cabinet for low-altitude logistics terminals with adjustable storage space. Background Technology

[0002] With the rapid development of low-altitude logistics networks, terminal receiving facilities for drone delivery have become a crucial link. Traditional smart parcel lockers, due to their fixed compartment sizes and enclosed structures, cannot adapt to the significantly different sizes and shapes of logistics vehicles delivered by drones (such as standard cargo boxes, special cargo packages, and temperature-controlled boxes), and also struggle to achieve automated handover. Existing infrastructure lacks consideration for the special processes of low-altitude logistics (such as rapid unloading, status confirmation, and energy replenishment), resulting in low last-mile receiving efficiency, complex operation, and limited application scenarios. Therefore, the industry urgently needs a smart low-altitude logistics terminal locker with flexible adjustable storage space, open and compatible interfaces, and intelligent collaboration with drones and back-end systems to solve the "last mile" receiving bottleneck caused by inconsistent physical specifications of delivery units and non-standardized operating processes, and to support the large-scale and automated operation of low-altitude logistics. Existing logistics lockers have certain shortcomings when used for low-altitude logistics. Traditional logistics lockers are only suitable for the storage and retrieval operations of regular logistics and express delivery. Low-altitude logistics mainly uses drones to achieve point-to-point rapid delivery. When logistics lockers are used for low-altitude logistics, it is necessary to solve the storage needs of drones and meet the charging and battery swapping needs of drones. Secondly, when dealing with items of different sizes, traditional logistics lockers cannot be adjusted according to the volume of the items, which reduces their applicability. Summary of the Invention

[0003] This invention provides an intelligent low-altitude logistics terminal cabinet with adjustable storage space, which solves the problem that traditional logistics cabinets in the prior art are only suitable for the storage and retrieval operations of conventional logistics and express delivery. Low-altitude logistics mainly utilizes drones to achieve point-to-point rapid delivery. When the logistics cabinet is used for low-altitude logistics, the problem of storing items for drones needs to be addressed. An intelligent low-altitude logistics terminal cabinet with adjustable storage space includes an outer shell and an inner frame. The inner frame is fixedly installed inside the outer shell. Two rows of storage partitions are movably installed on the inner surface of the inner frame. An access device is provided inside the inner frame on one side of the storage partitions. The access device includes a shelf and a movable base. The shelf is movably installed on the upper outer surface of the movable base. The front outer surface of the outer shell is provided with a retrieval compartment for use with the shelf. The upper outer surface of the outer shell is provided with a lifting platform.

[0004] As a further technical solution of the present invention, a vertical lead screw is movably installed at the middle position of one end of the movable base. The movable base and the vertical lead screw are connected by a thread. During operation, the vertical lead screw is driven to rotate by a motor, so that the vertical lead screw drives the movable base to move up and down by means of the thread structure, thereby completing the height adjustment of the movable base.

[0005] As a further technical solution of the present invention, a first transverse lead screw is movably installed at the upper end of the vertical lead screw, and a second transverse lead screw is movably installed at the lower end of the vertical lead screw. The second transverse lead screw and the first transverse lead screw are movably connected by a sprocket structure. During operation, the first transverse lead screw is driven by a motor, so that the first transverse lead screw drives the second transverse lead screw to rotate synchronously by means of the sprocket structure.

[0006] As a further technical solution of the present invention, the vertical lead screw and the second horizontal lead screw, as well as the vertical lead screw and the first horizontal lead screw, are all movably connected by a threaded slide. The inner side of the threaded slide is provided with a threaded groove. When the second horizontal lead screw and the first horizontal lead screw rotate synchronously, the threaded slide is driven by the second horizontal lead screw and the first horizontal lead screw, so that the threaded slide drives the vertical lead screw and the moving base to move laterally, thereby completing the lateral movement operation of the shelf. In addition, the vertical lead screw moves the moving base up and down, thereby completing the bidirectional position adjustment of the shelf.

[0007] As a further technical solution of the present invention, the storage plate and the movable base are movably connected by a screw. A guide slide rod is provided between the upper and lower sets of threaded slides to cooperate with the movable base. The guide slide rod can improve the stability of the movable base during up and down movement. At the same time, the screw rod is driven by a motor to move the storage plate outward and move the storage plate to the upper end of the corresponding storage partition, so that the items on the storage partition are placed on the upper end of the storage plate. One end of the storage plate has a sloping structure. When the storage plate is moved out of the movable base, the items on the storage partition are scooped into the upper end of the storage plate, completing the storage and retrieval operation of the items on the corresponding storage partition.

[0008] As a further technical solution of the present invention, the upper outer surface of the storage plate is provided with several sets of lifting buckles, which are symmetrically arranged. The lifting buckles are driven by an electric structure. The lifting buckles can be used to fix the bottom battery structure of the drone when the drone lands on the landing pad. The replacement of the drone battery can be completed by using the movable base in conjunction with the movement of the storage plate. The reserved battery can be stored at the upper end of the storage partition.

[0009] As a further technical solution of the present invention, two sets of docking sliders are fixedly installed at both ends of the storage partition, and the inner side of the inner frame is provided with a sliding groove for use with the docking sliders. The storage partition can be moved at the top using the docking sliders, and the spacing between the upper and lower sets of storage partitions can be adjusted when storing items of different sizes.

[0010] As a further technical solution of the present invention, a telescopic clamp is movably installed at one end of the docking slider, and a rack that works with the telescopic clamp is installed in the groove of the inner frame. During operation, the telescopic clamp is moved outward by the motor-driven screw, so that one end of the telescopic clamp is locked in the slot of the rack. The four sets of telescopic clamps and slots are docked and fixed to complete the fixing operation of the storage partition at the corresponding height.

[0011] As a further technical solution of the present invention, one end of the telescopic clamp has an inclined structure on its outer surface, and the lower part of the telescopic clamp that connects with the tooth groove is a planar structure. When an item is placed on the storage partition, the connection between the planar structure of the lower surface of one end of the telescopic clamp and the toothed rack can provide better support for the storage partition and prevent the storage partition from sagging.

[0012] As a further technical solution of the present invention, the front end of the outer shell is provided with a control panel at the upper part of the loading compartment, and two sets of positioning rods are movably installed on the inner side of the landing pad. The two sets of positioning rods are symmetrically arranged and driven by a motor in conjunction with a bidirectional lead screw. When the bidirectional lead screw rotates, it drives the two sets of positioning rods to move towards each other. When the drone lands on the landing pad, it can help fix the two sides of the drone and complete the limiting and fixing of the drone, so that the placement plate can be accurately moved to the position below the drone.

[0013] The beneficial effects of this invention are as follows: By setting up a storage and retrieval device, this invention solves the problem of storing and retrieving items between drones and logistics cabinets when the adjustable low-altitude logistics terminal smart cabinet is used. The storage and retrieval device is equipped with a transmission structure to realize the three-axis movement of the storage plate, receiving the goods from the top of the outer shell and delivering them to the corresponding storage partition. When the user retrieves the item by scanning the code or entering the retrieval code, the goods in the corresponding storage partition are automatically delivered to the retrieval compartment, the compartment door opens, and the user retrieves the item, thus improving the economic efficiency of low-altitude logistics. By setting up storage partitions, the use of the storage device is optimized when the adjustable low-altitude logistics terminal smart cabinet is used. The size of the storage space can be adjusted arbitrarily according to the volume of the items stored in the storage device, thereby expanding its applicability. Attached Figure Description

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-4 As shown, an adjustable low-altitude logistics terminal smart cabinet includes an outer shell 1 and an inner frame 7. The inner frame 7 is fixedly installed inside the outer shell 1. Two rows of storage partitions 8 are movably installed on the inner surface of the inner frame 7. An access device 9 is provided inside the inner frame 7 on one side of the storage partitions 8. The access device 9 includes a shelf 6 and a movable base 13. The shelf 6 is movably installed on the upper outer surface of the movable base 13. The front outer surface of the outer shell 1 is provided with a retrieval compartment 2 for use with the shelf 6. The upper outer surface of the outer shell 1 is provided with a lifting platform 4.

[0019] A vertical lead screw 12 is movably installed at the middle of one end of the movable base 13. The movable base 13 and the vertical lead screw 12 are connected by a thread. During operation, the vertical lead screw 12 is driven to rotate by a motor, so that the vertical lead screw 12 drives the movable base 13 to move up and down through the thread structure, thereby completing the height adjustment of the movable base 13.

[0020] A first transverse lead screw 10 is movably mounted on the upper end of the vertical lead screw 12, and a second transverse lead screw 11 is movably mounted on the lower end of the vertical lead screw 12. The second transverse lead screw 11 and the first transverse lead screw 10 are movably connected by a sprocket structure. During operation, the first transverse lead screw 10 is driven by a motor, so that the first transverse lead screw 10 drives the second transverse lead screw 11 to rotate synchronously by means of the sprocket structure.

[0021] The vertical lead screw 12 and the second horizontal lead screw 11, as well as the vertical lead screw 12 and the first horizontal lead screw 10, are all movably connected by a threaded slide 15. The inner side of the threaded slide 15 is provided with a threaded groove. When the second horizontal lead screw 11 and the first horizontal lead screw 10 rotate synchronously, the threaded slide 15 is driven by the second horizontal lead screw 11 and the first horizontal lead screw 10, so that the threaded slide 15 drives the vertical lead screw 12 and the moving base 13 to move laterally, thus completing the lateral movement operation of the shelf 6. In conjunction with the vertical lead screw 12 moving the moving base 13 up and down, the bidirectional position adjustment of the shelf 6 is completed.

[0022] The storage plate 6 and the movable base 13 are connected by a lead screw. A guide slide 14 is provided between the upper and lower sets of threaded slides 15 to cooperate with the movable base 13. The guide slide 14 can improve the stability of the movable base 13 during up and down movement. At the same time, the motor drives the lead screw to move the storage plate 6 outward, moving the storage plate 6 to the upper end of the corresponding storage partition 8, so that the items on the storage partition 8 are placed on the upper end of the storage plate 6. One end of the storage plate 6 has a sloping structure. When the storage plate 6 is moved out of the movable base 13, the items on the storage partition 8 are scooped into the upper end of the storage plate 6, completing the storage and retrieval operation of the items on the corresponding storage partition 8.

[0023] The upper outer surface of the shelf 6 is provided with several sets of lifting buckles 16. The two sets of lifting buckles 16 are arranged symmetrically along the middle of the shelf 6. The lifting buckles 16 are driven by an electric structure. The lifting buckles 16 can be used to fix the bottom battery structure of the drone when the drone lands at the landing pad 4. Then, the mobile base 13 is used in conjunction with the movement of the shelf 6 to complete the replacement of the drone battery. The reserved battery can be stored at the upper end of the storage partition 8.

[0024] Two sets of docking sliders 17 are fixedly installed at both ends of the storage partition 8. The inner side of the inner frame 7 is provided with a sliding groove for use with the docking sliders 17. The storage partition 8 can be moved at the top using the docking sliders 17. When storing items of different sizes, the spacing between the upper and lower sets of storage partitions 8 can be adjusted.

[0025] A telescopic clamp 18 is movably installed at one end of the docking slider 17. A rack that works with the telescopic clamp 18 is installed in the groove of the inner frame 7. During operation, the telescopic clamp 18 is moved outward by the motor-driven screw, so that one end of the telescopic clamp 18 is locked in the slot of the rack. By docking and fixing the four sets of telescopic clamps 18 and the slots, the storage partition 8 is fixed at the corresponding height.

[0026] The outer surface of one end of the telescopic clamp 18 is a beveled structure, and the lower part of the telescopic clamp 18 that connects with the tooth groove is a flat structure. When items are placed on the storage partition 8, the connection between the flat structure of the lower surface of one end of the telescopic clamp 18 and the toothed rack can provide better support for the storage partition 8 and prevent the storage partition 8 from sagging.

[0027] The front end of the outer shell 1 is located above the loading compartment 2 and has a control panel 3. Two sets of positioning rods 5 are movably installed on the inner side of the landing pad 4. The two sets of positioning rods 5 are symmetrically arranged and driven by a motor in conjunction with a bidirectional lead screw. When the bidirectional lead screw rotates, it drives the two sets of positioning rods 5 to move towards each other. When the drone lands on the landing pad 4, it can help fix the two sides of the drone and complete the limitation and fixation of the drone, so that the placement plate 6 can be accurately moved to the position below the drone.

[0028] An intelligent low-altitude logistics terminal cabinet with adjustable storage space utilizes a motor to drive a vertical lead screw 12 to rotate, causing the lead screw 12 to drive a movable base 13 to move up and down via a threaded structure, thus adjusting the height of the movable base 13. A second transverse lead screw 11 and a first transverse lead screw 10 drive a threaded slide 15, causing the threaded slide 15 to move the vertical lead screw 12 and the movable base 13 laterally, thus shifting the storage plate 6. Combined with the vertical movement of the movable base 13 via the vertical lead screw 12, this allows for the vertical movement of the storage plate 6. The bidirectional position adjustment, with the guide slide 14, can improve the stability of the moving base 13 during up and down movement. At the same time, the motor drives the lead screw, which drives the shelf 6 to move outward, moving the shelf 6 to the upper end of the corresponding storage partition 8, so that the items on the storage partition 8 are placed on the upper end of the shelf 6. One end of the shelf 6 has a sloping structure. When the shelf 6 is moved out of the moving base 13, the items on the storage partition 8 are scooped into the upper end of the shelf 6, completing the storage and retrieval operation of the items on the corresponding storage partition 8. Move the shelf 6 to the lower part of the storage partition 8. Adjust the height of the storage partition 8 by moving the shelf 6 up and down. When the storage partition 8 is moved to the corresponding height, use the motor to drive the lead screw to move the telescopic head 18 outward, so that one end of the telescopic head 18 is locked in the slot of the rack. The four sets of telescopic heads 18 are fixed by the docking between them and the slots. The storage partition 8 is fixed at the corresponding height. When items are placed on the storage partition 8, the docking between the flat structure of the lower surface of one end of the telescopic head 18 and the rack can provide better support for the storage partition 8 and prevent the storage partition 8 from sagging.

[0029] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
