Description

Technical Field

[0001] This invention relates to the field of drone logistics delivery system technology, and specifically to a delivery station for a drone logistics delivery system. Background Technology

[0002] In recent years, the rapid development and widespread application of drone technology have spurred a new market opportunity—the low-altitude economy. This is no longer limited to traditional aerial photography or simple entertainment purposes, but has penetrated into many high-value fields such as logistics and delivery, agricultural plant protection, disaster response, and environmental monitoring. However, although the technology of drones themselves is becoming increasingly mature, the basic ground infrastructure supporting their large-scale commercial use is relatively lagging behind, especially in addressing pain points such as energy supply and last-mile logistics.

[0003] Existing drone logistics delivery systems, as shown in Reference Document 1 (CN204198183U), primarily utilize rooftop helipads and cargo sorting lockers to receive and store drone cargo, thus addressing the low efficiency issue of traditional manual delivery. Reference Document 2 (CN107134070A) further proposes a drone-based express delivery system that achieves automated sorting and transport through package delivery devices, storage lockers, and pickup conveyor systems. However, existing technologies still suffer from the following key technical bottlenecks: Insufficient positioning accuracy and stability: Comparative document 1 only achieves rough positioning through a wireless receiver and a stepper motor, failing to solve the problem of precise fixation when the drone lands; although the positioning component of comparative document 2 mentions remote identification, it lacks a two-way positioning design at the mechanical structure level, making it susceptible to environmental interference that leads to positioning deviation.

[0004] Limited battery life: The existing system does not take into account the contact charging technology of the drone's outriggers, and neither of the comparison documents 1 and 2 mentions the charging function of the drone at the delivery station, which limits the drone's continuous operation capability.

[0005] Lack of automation dimension in handling: The picking and conveying device in Comparative Document 2 only realizes two-dimensional planar handling and does not solve the problem of precise lifting and positioning of the cargo box in the Z-axis direction; existing technologies generally lack three-dimensional spatial positioning systems, making it difficult to adapt to the automated loading and unloading needs of cargo boxes of different sizes.

[0006] Low adaptability and low space utilization: The fixed support door structure cannot adapt to the leg spacing of different drone models; the storage cabinet compartment design does not take into account package volume recognition, resulting in low space utilization.

[0007] To address the aforementioned issues, this invention achieves a technological breakthrough through the following innovations: Innovation in the support door assembly: The use of an electrode stud-electrode plate structure enables contact charging of the drone's legs, and the design of sliding wheels and sliding channels allows for adjustment of the opening and closing degree of the support door, adapting to the leg spacing of different drone models and solving the problems of battery life and compatibility.

[0008] Two-way positioning mechanism: Introducing a mechanical structure of forward and reverse rotating screws and nuts to achieve precise positioning in both left and right / front and back directions. It works in conjunction with the gear and rack drive of the top hatch to improve the stability and positioning accuracy of the UAV landing.

[0009] Three-dimensional motion platform: The lateral conveying component (synchronous belt + pulley drive) and the longitudinal conveying component (longitudinal pulley pressure plate + intermediate connecting plate) constitute a two-dimensional motion platform. Together with the lifting forks of the cargo receiving component, it realizes the precise positioning and automated handling of the cargo in three-dimensional space along the X / Y / Z axes, solving the problem of missing dimensions in the handling automation.

[0010] This invention, through the aforementioned innovations, not only solves the problems of low positioning accuracy, lack of charging function, and insufficient automation in handling of drones in existing technologies, but also improves the flexibility and efficiency of logistics systems through three-dimensional spatial positioning and intelligent adaptation design. Specifically, the charging function of the support door extends the drone's operating time, the bidirectional positioning mechanism ensures landing stability, and the three-dimensional motion platform enables fully automated loading and unloading of cargo boxes. Ultimately, it provides key technical support for the large-scale application of drone logistics delivery, promoting the upgrade of the logistics industry towards intelligence and unmanned operation. Summary of the Invention

[0011] The purpose of this invention is to provide a delivery station for a drone logistics delivery system, which addresses the aforementioned problems. This station not only solves the problems of low drone positioning accuracy, lack of charging function, and insufficient automation in handling in the prior art, but also improves the flexibility and efficiency of the logistics system through three-dimensional spatial positioning and intelligent adaptation design.

[0012] The technical solution of the present invention is as follows: The present invention provides a delivery station for a drone logistics delivery system, comprising: The top frame (1) has multiple mounting points, which serve as the base of the overall structure. The multiple mounting points support key components such as the hatch assembly and positioning assembly, ensuring the stability and scalability of the system structure.

[0013] The top hatch assembly (2) includes two symmetrically arranged hatches (2-1), a rack (2-2), a gear (2-3), a hatch drive (2-4), and a hatch sliding pair (2-5). The hatches are opened and closed through the gear and rack. The rotational motion of the hatch drive (2-4) is converted into the linear opening and closing motion of the hatch (2-1) through the meshing of the gear (2-3) and the rack (2-2), thereby achieving precise and low-friction hatch control. The sliding pair (2-5) ensures smooth movement during the opening and closing of the hatch, reduces shaking, and improves system reliability.

[0014] The support door assembly (3) includes a support door (3-1) and a sliding channel (3-2). The support door (3-1) is composed of an electrode plate (3-1a), an electrode stud (3-1b), an insulating support plate (3-1c), a support frame (3-1d), and a sliding wheel (3-1e). The electrode stud (3-1b) is welded to the electrode plate (3-1a). The support door (3-1) adjusts its opening and closing degree along the sliding channel (3-2) via the sliding wheel (3-1e) to suit various needs. It is compatible with different models of drones and is charged by contacting the drone's leg contacts through the electrode stud (3-1b). The sliding wheel (3-1e) and the sliding channel (3-2) cooperate to make the opening and closing degree of the support door (3-1) adjustable to adapt to the leg spacing of different models of drones. The electrode plate (3-1a) and the electrode stud (3-1b) achieve automatic charging by contacting the drone's leg contacts. The insulating support plate (3-1c) prevents electrical short circuits, and the support frame (3-1d) provides structural strength.

[0015] The UAV positioning component (4) includes a left and right positioning mechanism (4-1) and a front and rear positioning mechanism (4-2). It adopts a mechanical structure of a forward and reverse spiral screw (4-1c) and a forward and reverse spiral nut (4-1d) to achieve bidirectional positioning. It works in coordination with the gear and rack drive of the top hatch (2). The left and right / front and rear positioning mechanisms (4-1 / 4-2) adopt a structure of a forward and reverse spiral screw (4-1c) and a forward and reverse spiral nut (4-1d). The positioning plate moves synchronously closer to / away from the top hatch through a single drive source to ensure accurate fixation when the UAV lands. The UAV positioning component is linked with the gear and rack drive of the top hatch to optimize the operation process.

[0016] The lower frame (5) is provided with a support member (5-1) and a longitudinal sliding pair (5-2). The support member (5-1) provides the mounting base for the longitudinal conveying assembly, and the longitudinal sliding pair (5-2) ensures that the conveying assembly moves smoothly along the track and reduces mechanical wear.

[0017] The transverse transport assembly (6) and the longitudinal transport assembly (7) are driven by a timing belt (6-3), a drive pulley (6-2), and a driven pulley (6-8). The longitudinal transport assembly (7) is connected to the intermediate connecting plate (6-5) via a longitudinal pulley pressure plate (7-5). The two constitute a two-dimensional motion platform. The transverse transport assembly (6) realizes the transverse movement of the cargo box via a timing belt (6-3), a drive pulley (6-2), and a driven pulley (6-8). The longitudinal transport assembly (7) is connected to the intermediate connecting plate (6-5) via a longitudinal pulley pressure plate (7-5), which drives the transverse assembly to move longitudinally as a whole, thus forming a precise transport system in the plane.

[0018] The cargo box receiving component (8) includes a lifting drive component (8-1) and a lifting fork (8-2). It works with the lateral transport component (6) and the longitudinal transport component (7) to achieve three-dimensional spatial positioning of the cargo box. The lifting fork (8-2) is vertically lifted and lowered under the action of the lifting drive component (8-1). It works with the lateral / longitudinal transport components to achieve three-dimensional spatial positioning of the cargo box on the X, Y, and Z axes, adapting to the loading and unloading needs of cargo boxes of different sizes.

[0019] The weighing and picking component (9) monitors the weight of the cargo box in real time. The non-powered roller group (9-2) reduces friction. The picking tray (9-3) pulls the cargo box out / pulls it back through the telescopic slide rail (9-5). The picking tray does not contact the bottom of the cargo box during weighing, thus avoiding measurement errors. The electric push rod (10-1) of the safety door (10) drives the door panel (10-3) to open and close along the slide rail (10-2), ensuring operational safety. The interactive display screen (12) is located on the front side of the outer cover (11) and supports user interactive operation. The positioning mark (13) is set on the top surface of the delivery station and guides the drone's position calibration before landing through vision or sensors.

[0020] Furthermore, the support door assembly (3) also includes an auxiliary fixing component (3-3) and a support door drive component (3-4). The support door (3-1) is connected to the sliding channel (3-2) through a sliding wheel (3-1e). Under the drive of the drive component (3-4), it moves along the channel direction and is fixedly connected to the top frame (1) through the auxiliary fixing component (3-3). The auxiliary fixing component (3-3) enhances the vibration resistance of the support door and the top frame through mechanical connection, prevents structural loosening caused by the impact of UAV landing or mechanical movement, and improves the reliability of long-term system operation. The support door drive component (3-4) adopts electric / hydraulic drive to realize the automatic opening and closing adjustment of the support door, accurately adapts to the leg spacing of different UAV models, and reduces the movement resistance and improves the smoothness of opening and closing and positioning accuracy through the rolling friction design of the sliding wheel (3-1e) and the sliding channel (3-2).

[0021] Furthermore, the left and right positioning mechanism (4-1) of the UAV positioning component (4) includes a drive component (4-1a), a positioning plate (4-1b), a forward and reverse helical screw (4-1c), and a nut (4-1d). The drive component drives the screw to rotate, causing the nut to move closer to or further away from the center of the screw, thereby driving the positioning plate to complete the left and right positioning. The front and rear positioning mechanism (4-2) adopts the same structure to achieve front and rear positioning. The two are arranged perpendicular to each other. The forward and reverse helical screw (4-1c) and the nut (4-1d) use the difference in the direction of the screw thread to achieve single-drive source synchronous control of the two positioning plates to move closer to or further away, ensuring the symmetry and accuracy of the left and right / front and rear positioning, and eliminating the offset risk of traditional single-sided positioning. The rotational power is converted into the linear motion of the positioning plate through screw transmission, realizing the bidirectional mechanical fixation of the UAV. The spatially vertical layout of the left and right / front and rear positioning mechanism eliminates motion interference and ensures accurate positioning in the horizontal plane.

[0022] Furthermore, the lateral conveying assembly (6) includes a lateral drive component (6-1), a drive pulley (6-2), a timing belt (6-3), a lateral sliding pair (6-4), an intermediate connecting plate (6-5), a transition bracket (6-6), a side plate (6-7), a driven pulley (6-8), and a pulley pressure plate (6-9); the timing belt (6-3) meshes with the drive pulley (6-2) and the driven pulley (6-8), and is pressed by the pulley pressure plate (6-9) on the lateral drive component (6-1). Driven by the lateral movement of the cargo receiving component (8), the synchronous belt (6-3) and the pulley pressure plate (6-9) mesh with each other to achieve slip-free transmission, ensuring precise control of the lateral movement; the pulley pressure plate clamping design prevents the synchronous belt from slipping and improves transmission reliability; the lateral sliding pair (6-4) and the intermediate connecting plate (6-5): the sliding pair provides a linear guide to reduce friction and improve the stability of lateral handling; the intermediate connecting plate serves as the hub of the lateral and longitudinal components, realizing the structural integration and power transmission of the two-dimensional motion platform.

[0023] Furthermore, the longitudinal transport assembly (7) includes a longitudinal drive component (7-1), a second drive pulley (7-2), a second synchronous belt (7-3), a second driven pulley (7-4), and a longitudinal pulley pressure plate (7-5). The longitudinal pulley pressure plate (7-5) is connected to the intermediate connecting plate (6-5), and the second synchronous belt (7-3) meshes and presses against the longitudinal pulley pressure plate (7-5). Driven by the longitudinal drive component (7-1), it drives the transverse transport assembly (6) to move longitudinally as a whole. The pressure plate presses against the synchronous belt to ensure longitudinal slip transmission and improve positioning accuracy. The driven pulley forms tension balance through its upper and lower layout to ensure the stability of the synchronous belt transmission. The longitudinal drive component (7-1) provides a longitudinal power source and drives the transverse transport assembly to move longitudinally as a whole through the synchronous belt transmission, thereby achieving precise positioning of the cargo box in the Y-axis direction and completing two-dimensional planar transport in coordination with the transverse movement.

[0024] Furthermore, the lifting forks (8-2) of the cargo box receiving component (8) are lifted and lowered under the drive of the lifting drive component (8-1), and together with the lateral transport component (6) and the longitudinal transport component (7), the cargo box is positioned in three-dimensional space along the X, Y, and Z axes. The lifting forks (8-2) and the lifting drive component (8-1) achieve the positioning of the cargo box in the Z-axis direction through vertical lifting and lowering, and together with the lateral / longitudinal transport components, the cargo box is accurately loaded and unloaded in three-dimensional space. The lifting drive component provides smooth lifting power to ensure the stability of the cargo box during the transport process.

[0025] Furthermore, the weighing and picking assembly (9) includes a weighing sensor (9-1), a non-powered roller assembly (9-2), a picking tray (9-3), a bracket (9-4), and a telescopic slide rail (9-5). When the cargo box is placed on the non-powered roller assembly (9-2), the weighing sensor (9-1) measures the weight of the cargo box, and the picking tray (9-3) is pulled out or pushed back through the telescopic slide rail (9-5). During weighing, the picking tray (9-3) does not contact the bottom surface of the cargo box, and the rolling friction reduces the resistance to the movement of the cargo box, making it easy for the user to operate manually. The telescopic slide rail ensures the straight trajectory of the picking tray being pulled out / pushed back, improving the smoothness of operation. The weighing sensor (9-1) monitors the weight of the cargo box in real time and provides accurate logistics data. The non-contact design between the picking tray and the bottom surface of the cargo box avoids weighing interference and ensures the accuracy of weight measurement.

[0026] Furthermore, the safety door (10) includes an electric push rod (10-1), a slide rail (10-2), and a door panel (10-3); the electric push rod (10-1) drives the door panel (10-3) to open and close along the slide rail (10-2), and the two sides of the door panel (10-3) are fixedly connected to the slide rail (10-2). The electric push rod (10-1) and the slide rail (10-2) achieve rapid response and precise control of the automatic opening and closing power; the slide rail provides a linear guide to reduce friction, improve the stability and durability of the door panel movement, and the fixed sides ensure the structural stability of the door panel during movement, prevent shaking or deviation, and ensure operational safety.

[0027] Furthermore, the outer cover (11) is installed on the outer perimeter of the lower frame (5), and the interactive display screen (12) is set above the safety door (10) on the front side of the outer cover (11). It is used for users to interact with the delivery station to realize the storage and delivery of cargo boxes. The outer cover (11) protects the internal components from environmental corrosion (such as rain and dust) and extends the service life of the equipment. The interactive display screen (12) provides an interactive interface between the user and the system, and supports functions such as inputting cargo box storage and retrieval instructions and querying status. Located above the safety door, it is convenient for users to observe information at the same time during operation, thus optimizing the human-computer interaction experience.

[0028] Furthermore, the positioning marker (13) is set on the top surface of the delivery station to guide the position calibration of the UAV before landing, ensuring that the UAV lands accurately on the support door (3-1). The positioning marker (13) guides the position calibration of the UAV before landing through visual markers (such as QR codes, LED light arrays) or sensors, ensuring that the UAV lands accurately on the support door (3-1). The top surface layout utilizes the high-altitude perspective characteristics of the UAV to ensure the visibility of the marker during the landing process, thereby improving landing accuracy and safety.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The present invention provides a support door assembly for a delivery station of a drone logistics delivery system. It innovatively adopts an electrode stud-electrode plate structure to realize contact charging of drone legs, and realizes the opening degree adjustment of the support door through the design of sliding wheels and sliding channels to adapt to the leg spacing of different drone models, thus solving the problems of battery life and compatibility.

[0030] 2. This invention introduces a mechanical structure of forward and reverse spiral screws and nuts to achieve precise positioning in both left and right / front and back directions. This works in conjunction with the gear and rack drive of the top hatch to improve the landing stability and positioning accuracy of the UAV.

[0031] 3. The transverse and longitudinal transport components of this invention constitute a two-dimensional motion platform, which, together with the lifting forks of the cargo receiving component, enables precise positioning and automated transport of the cargo in three-dimensional space along the X / Y / Z axes, thus solving the problem of missing dimensions in transport automation.

[0033] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0034] Any feature disclosed in this specification (including any appended claims and abstract) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0035] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0036] like Figures 1-12 As shown, in order to realize the delivery station of the UAV logistics delivery system described in this invention, corresponding components are designed, including top frame (1), top door assembly (2), support door assembly (3), UAV positioning assembly (4), lower frame (5), lateral transport assembly (6), longitudinal transport assembly (7), cargo box receiving assembly (8), weighing and picking assembly (9), safety door (10), outer cover (11), interactive display screen (12), and positioning mark (13).

[0037] When the drone flies over the delivery station, it identifies the positioning mark (13) set on the top surface of the delivery station, adjusts its attitude before landing, and after the attitude is adjusted, the drone interacts with the delivery station to confirm the drone model and the task to be performed. The task can be divided into delivery, pickup, charging, and temporary parking. like Figures 2-9 As shown, when the drone needs to perform a delivery task, the two doors (2-1) on the top of the delivery station open. The support door assembly (3) controls the opening and closing degree of the support door (3-1) according to the model of the drone to adapt to the size of the current model of drone. After the drone lands on the support door (3-1), the left and right positioning mechanism (4-1) and the front and rear positioning mechanism (4-2) of the drone positioning assembly (4) accurately calibrate the position of the drone. The lateral transport assembly (6) and the longitudinal transport assembly (7) move, driving the cargo box receiving assembly (8) to move directly below the drone and the support door (3-1). The lifting drive component (8-1) drives the lifting fork (8-2) to rise to near the cargo box carried by the drone. The delivery station sends a message to the drone. After the drone releases the cargo box it carries onto the lifting fork (8-2), the lifting fork (8-2) descends and, driven by the lateral transport assembly (6) and the longitudinal transport assembly (7), places the cargo box on the empty cargo support component (5-1) to complete the drone delivery task. like Figures 6-8 As shown, when the drone needs to perform a pickup task, the lifting forks (8-2) driven by the lateral transport component (6) and the longitudinal transport component (7) remove the cargo box to be picked up from the support (5-1) and send the cargo box to the drone. The drone catches the cargo box and sends it to the required destination. like Figures 2-5As shown, when the UAV needs to perform a charging task, the two hatches (2-1) on the top of the delivery station open. The support door assembly (3) controls the opening and closing degree of the support door (3-1) according to the model of the UAV to adapt to the size of the current model of UAV. After the UAV lands on the support door (3-1), the left and right positioning mechanism (4-1) and the front and rear positioning mechanism (4-2) of the UAV positioning assembly (4) accurately calibrate the position of the UAV. The UAV interacts with the delivery station. The delivery station introduces the positive and negative terminals of the power supply to charge the UAV through the electrode studs (3-1b) on the two support doors (3-1). At the same time, the two hatches (2-1) on the top of the delivery station are closed to prevent damage to the UAV and the delivery station caused by strong winds or rain. When the UAV needs to perform a temporary parking task, the two hatches (2-1) on the top of the delivery station open. The support door assembly (3) controls the opening and closing degree of the support door (3-1) according to the model of the UAV to adapt to the size of the current model of UAV. After the UAV lands on the support door (3-1), the left and right positioning mechanism (4-1) and the front and rear positioning mechanism (4-2) of the UAV positioning assembly (4) accurately calibrate the position of the UAV. After that, the two hatches (2-1) on the top of the delivery station close.

[0038] The user interaction process with the delivery station is divided into pickup and delivery: like Figures 7-11 As shown, when a user needs to pick up goods from the delivery station, the user interacts with the delivery station through the interactive display screen (12). The user can scan the code with their mobile phone or enter the pickup code to give the delivery station the information of the goods to be picked up. The lifting forks (8-2) driven by the horizontal transport component (6) and the vertical transport component (7) send the user's corresponding cargo box to the non-powered roller group (9-2) of the weighing and picking component (9). The safety door (10) controls the door panel (10-3) to open. The user pulls out the cargo box through the handle on the picking tray (9-3) and takes out the goods from the cargo box. After the user takes out the goods, the delivery station will prompt the user to push the cargo box into the delivery station through voice. Then the safety door (10) controls the door panel (10-3) to close, completing the user's picking process. like Figures 6-12As shown, when a user needs to deliver goods through the delivery station, the user interacts with the delivery station through the interactive display screen (12). The user can place an order by scanning a QR code with their mobile phone and enter the correct shipping information. The delivery station checks whether there are empty boxes inside. If there are empty boxes, the horizontal transport component (6) and the vertical transport component (7) drive the lifting fork (8-2) to send the empty box to the position of the non-powered roller group (9-2) and the pickup tray (9-3) of the weighing and picking component (9). Then the safety door (10) controls the door panel (10-3) to open. The user pulls out the empty box and puts the goods into the box through the handle on the pickup tray (9-3). Inside, the cargo box containing the goods is pushed into the delivery station through the handle on the pickup tray (9-3). The weighing sensor (9-1) under the non-powered roller assembly (9-2) weighs the cargo box containing the goods. If the weight exceeds the limit, the delivery station will prompt the user through voice that the weight exceeds the limit and delivery cannot be made. If the weight meets the requirements, the horizontal transport assembly (6) and the vertical transport assembly (7) drive the lifting fork (8-2) to take away the cargo box at the position of the non-powered roller assembly (9-2) and the pickup tray (9-3) and place it on the corresponding cargo support (5-1). At the same time, the safety door (10) controls the door panel (10-3) to close.

[0039] When a delivery station of a drone logistics delivery system has goods that need to be delivered by drone, the delivery station will interact with the cloud management system and transmit the information of the goods to be delivered to the cloud management system. The management system will then dispatch drones near the delivery station to the designated delivery station to pick up the goods and deliver them to the destination specified by the user.

[0040] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
