Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) logistics technology, specifically to an unmanned logistics transportation system. Background Technology

[0002] Mobile hangars and mobile helipads are core ground support equipment for drones to achieve long-endurance, wide-area, and unattended operations. The key difference between the two is that mobile helipads focus on take-off, landing, and basic charging; while mobile hangars integrate storage, protection, automatic battery swapping, charging, maintenance, and intelligent scheduling, making them a more complete "mobile home port."

[0003] The application of unmanned logistics currently faces the following problems: Battery life bottleneck: mainstream industrial drones can only fly for 20-40 minutes on a single charge, which cannot meet the needs of long-term inspection, emergency rescue, logistics and delivery.

[0004] Unmanned and large-scale: Manual battery swapping, take-off and landing, and maintenance are inefficient, costly, and risky, and there is an urgent need for automated ground stations to support the collaboration of "machine group-vehicle group".

[0005] High failure rate due to multi-mechanism linkage: The opening and closing of the top cover, the lifting, translation, rotation, battery swapping of the robotic arm, centering and clamping, etc. are all coordinated. Failure in any part will lead to the overall failure.

[0006] Excessive size and weight: Integration results in bulky hangars, high requirements for load capacity and maneuverability of vehicle-mounted and ship-mounted platforms, and reduced deployment flexibility.

[0007] High maintenance costs: Precision transmission, servo, and sensor require frequent calibration and maintenance, making field maintenance difficult.

[0008] In response, the applicant leverages industry collaboration technologies to accelerate the deployment and promotion of drones in the logistics system. By integrating drones and unmanned vehicles with traditional logistics, a three-dimensional "air + ground" delivery system is formed, with leading enterprises actively deploying collaborative networks. Simultaneously, this drives the upgrading of upstream and downstream industries, builds a collaborative ecosystem, and promotes the transformation of the express delivery industry towards intelligence and efficiency.

[0009] Meanwhile, the surge in logistics demand and the shortage of last-mile delivery are the core drivers of their development. my country's express delivery and on-demand delivery orders continue to climb, but there is a shortage of human delivery resources, with a prominent problem of "difficulty in recruiting." Traditional delivery methods have significant shortcomings in remote areas, congested urban roads, and the "last five kilometers," and the need for cost reduction and efficiency improvement provides a vast market space for unmanned delivery.

[0010] Currently, drone transportation is mainly focused on single-item delivery, and production capacity cannot meet the needs of large-scale use. Therefore, unmanned vehicles and drones cannot be combined for logistics transportation to achieve the effect of cost reduction and efficiency improvement. Summary of the Invention

[0011] To address the technical problems existing in the background art, the present invention provides an unmanned logistics transportation system.

[0012] The technical solution of this invention is as follows: An unmanned logistics transportation system includes a mobile hangar, an unmanned vehicle picking unit, and a terminal docking unit.

[0013] The mobile hangar has an upper and lower parking apron on its top sides. Sorting and maintenance units are located below the two ends of the upper parking apron, respectively. A conveyor line is installed above the upper parking apron to move drones from the sorting unit to the maintenance unit. A conveyor line is also installed between the maintenance unit and the lower parking apron.

[0014] A battery swapping and storage compartment is set up on one side of the helipad for replacing and storing drone batteries.

[0015] The unmanned vehicle picking unit includes a lifting mechanism located on the side wall of the mobile hangar. The top of the lifting mechanism connects to the exit side of the sorting unit, which is used to transport the sorted boxes to the unmanned vehicle on the ground.

[0016] The terminal docking unit can dock with unmanned vehicles or drones to connect to cargo containers.

[0017] By coordinating the operations of drones and unmanned vehicles, a three-dimensional "air + ground" delivery system is formed. By connecting unmanned vehicles with terminal docking units, the problem of the last five kilometers of traditional delivery is solved, thus systematizing the application of drones in logistics and facilitating its promotion and application.

[0018] In one implementation, the upper helipad has a U-shaped structure, with a loading door at one end for docking the drone and an elevator at the other end for transporting the drone to the maintenance unit below. A conveyor line is installed between the loading door and the elevator.

[0019] In one implementation, the sorting unit includes an upper conveyor and a lower conveyor.

[0020] The upper conveyor system includes a main conveyor line and a secondary conveyor line. One end of the main conveyor line is located below the unloading gate, and the other end is connected to several cargo boxes at intervals. A quick identification zone is set between the unloading gate and the cargo boxes.

[0021] The secondary transport line is connected in parallel to the main transport line. One end of the secondary line connects the rapid identification zone and the cargo container, while the other end transports goods in the opposite direction of the main transport line. At the end of the transport line, there is a rejection cargo container.

[0022] The lower conveyor surrounds the upper conveyor and has several conveyor rollers inside that extend to the bottom of each cargo box to move the cargo box to a different position.

[0023] The lower transmission machine is connected to the edge of the mobile hangar via an extension cable for docking with the lifting mechanism.

[0024] Furthermore, a graded processing device is installed in front of the rapid identification area on the main transport line to prevent express packages from being stacked or multiple packages from being passed side by side, thereby controlling the delivery of express packages one by one along the main transport line.

[0025] In one implementation, the elevator is located at the opening edge of the U-shaped upper parking apron. The maintenance unit includes a temporary storage area, an activity area, and a repair area. The temporary storage area is located at the edge of the mobile hangar on the side away from the sorting unit, and the activity area is directly opposite the elevator door.

[0026] In one implementation, the battery swapping storage area includes a battery swapping area and a storage area, with a conveyor line connecting the two, and the lower parking apron located on one side of the conveyor line between them.

[0027] As an overall optimized layout structure, the upper and lower parking aprons are arranged one in front of the other on the top of the mobile hangar. The maintenance unit and sorting unit are distributed on the left and right sides below the upper parking apron, the lower parking apron is located behind the sorting unit, and the battery swapping storage bin is located on the left side of the lower parking apron. The unmanned vehicle pickup unit is located directly in front of the sorting unit.

[0028] As one implementation method, the lifting mechanism is equipped with telescopic forks for picking up and placing cargo boxes.

[0029] As one implementation method, the terminal docking unit includes a housing, with express sorting components and cargo storage components respectively arranged on both sides of its interior. The box is equipped with a telescopic guide groove above the inlet end of the express sorting component to clamp the box, and a rotating boom is installed on the outer box wall to transfer the box from the unmanned vehicle into the telescopic guide groove. The cargo storage unit is equipped with storage compartments of different sizes, and a human-machine interface window is installed on the back wall of the box.

[0030] Furthermore, the cargo storage component uses a robotic arm to transport packages from the end of the express sorting component to storage compartments or pickup points. The robotic arm's control program is set to store multiple packages belonging to the same person in the same storage compartment until the largest storage compartment can no longer hold the packages, at which point it searches for other storage compartments.

[0031] The beneficial effects of this invention are that, compared with traditional point-to-point single-line delivery by drones, this invention, by constructing a mobile drone hangar and a mobile landing pad on it, can be flexibly deployed and centrally receive drones and packages within a certain area. Because it is located close to the target area, the volume of packages will be relatively reduced, and the space required for the site will be reduced. It breaks through the pain points of traditional fixed airports, such as limited site space, cumbersome site selection, and inability to dynamically follow up on tasks. Relying on modular and lightweight structural design, it can be adapted to mobile carriers such as ships and can also be quickly deployed and retracted in remote areas, meeting the immediate deployment needs of emergency rescue, line inspection, field survey and other sudden tasks.

[0032] This invention integrates high-precision positioning sensing, automatic centering correction, and intelligent linkage control technologies to achieve fully autonomous and precise take-off and landing, and smooth centering and alignment of drones. Coupled with an intelligent charging and battery swapping system, it can perform wireless fast charging, wired voltage-regulated charging, and automated battery replacement, solving the industry problems of short single-charge drone flight time and low efficiency of manual battery swapping. It can also be equipped with protective structures such as sealed protection, temperature control and dehumidification, wind and rain protection, and sand and dust corrosion resistance to build an all-weather operation support system that is not afraid of high and low temperatures, rain, snow, fog and haze, and other harsh environments, providing comprehensive protection for drones and onboard equipment.

[0033] Compared to traditional take-off and landing equipment, this invention significantly improves the endurance and operational coverage of drones, enabling fully unmanned operation and maintenance management without the need for on-site human supervision or manual intervention. This reduces manpower input and maintenance costs, while also avoiding risks such as take-off and landing errors and equipment damage caused by manual operation, significantly reducing equipment failure rates and ensuring operational continuity and stability. It can be widely adapted to various scenarios such as power line inspection, security monitoring, emergency rescue, logistics distribution, and land surveying, meeting the needs of long-term, large-scale, and high-efficiency continuous unmanned operation, and comprehensively improving the intelligence level and practical capabilities of the drone operation system.

[0034] Currently, most low-altitude logistics transportation and sorting terminal equipment on the market involves a single drone delivering a single package, while this invention allows a single drone to transport packages in batches, thus fulfilling the design goal of reducing costs and increasing efficiency.

[0035] By designing a unique storage structure through terminal docking units, multiple packages belonging to the same person can be stored in one place, improving package retrieval efficiency. Attached Figure Description

[0037] Example 1 Combination Figure 1-9 This embodiment provides an unmanned logistics transportation system, including a mobile hangar, an unmanned vehicle picking unit 6, and a terminal docking unit 7.

[0038] The mobile hangar has an upper parking apron 1 and a lower parking apron 2 on its top sides. Sorting units 3 and maintenance units 4 are located below the two ends of the upper parking apron 1. A conveyor line is installed above the upper parking apron 1 for the drone to move from the sorting unit 3 to the maintenance unit 4. A conveyor line is installed between the maintenance unit 4 and the lower parking apron 2.

[0039] A battery swapping and storage compartment 5 is set up on one side of the lower parking apron 2 for replacing and storing the batteries of drones.

[0040] The unmanned vehicle picking unit 6 includes a lifting mechanism 61 located on the side wall of the mobile hangar. The top of the lifting mechanism 61 is connected to the exit side of the sorting unit 3, which is used to transport the sorted boxes 34 to the unmanned vehicle on the ground.

[0041] The terminal docking unit 7 can dock with the cargo box 34 of an unmanned vehicle or drone.

[0042] By coordinating the operations of drones and unmanned vehicles, a three-dimensional "air + ground" delivery system is formed. Through the docking of unmanned vehicles with terminal docking unit 7, the problem of the last five kilometers of traditional delivery is solved, thus systematizing the application of drones in logistics and facilitating its promotion and application.

[0043] As an overall optimized layout structure, the upper parking apron 1 and the lower parking apron 2 are arranged one in front of the other on the top of the mobile hangar. The maintenance unit 4 and the sorting unit 3 are distributed on the left and right sides below the upper parking apron 1. The lower parking apron 2 is located behind the sorting unit 3, and the battery swapping storage compartment 5 is located on the left side of the lower parking apron 2.

[0044] In this way, the drones travel in an S-shaped route from landing on the upper parking apron 1 above the sorting unit 3 to being stored in the battery swapping and storage warehouse 5 along the transport line, making the drone transport line as long as possible in a limited space to accommodate multiple drones working at different workstations.

[0045] The unmanned vehicle pickup unit 6 is located directly in front of the sorting unit 3. This route is kept as short as possible to reduce costs, shorten the time packages spend on the roof, and get them to the unmanned vehicle on the ground as quickly as possible.

[0046] Let's combine the following... Figure 1 and Figure 2 The upper helipad 1 has a U-shaped structure, with its lower part connected to the top of the mobile hangar via several columns. The two ends are work areas, while the middle section is used solely for drone transport. One end of the upper helipad 1 has a loading door for docking drones, and the other end has an elevator 41 for transporting drones to the lower maintenance unit 4. A conveyor line connects the loading door and the elevator 41.

[0047] Once the drone, carrying its lower payload, reaches the landing position, it communicates with sorting unit 3 to open the unloading door, then places the payload into the unloading area to complete the unloading. After unloading, the drone quickly reaches elevator 41 via a conveyor line. If all monitoring indicators are normal, it proceeds to the lower level and then via a conveyor line to the lower parking apron 2. If any abnormal indicators are found, it enters maintenance unit 4 for repair.

[0048] See Figure 3 and Figure 5 , Figure 3 The diagram shows the sorting unit 3 and maintenance unit 4 exposed by removing the upper apron 1. The sorting unit 3 includes an upper conveyor 31 and a lower conveyor 32. The express delivery is first sorted on the upper conveyor 31, and then the sorted goods are quickly packed into boxes. The lower conveyor 32 then transports the boxes 34 to the docking position of the unmanned vehicle picking unit 6.

[0049] See details Figure 5The upper conveyor 31 is a belt conveyor structure, including a main conveyor line 311 and a secondary conveyor line 312. One end of the main conveyor line 311 is located below the unloading gate, and a baffle is installed between it and the unloading gate. The other end is connected to several cargo boxes 34 at intervals. A quick identification zone 33 is set between the unloading gate and the cargo boxes 34. The express delivery direction of the main conveyor line 311 is shown in [reference needed]. Figure 5 As indicated by the solid arrow in the middle.

[0050] The rapid identification zone 33 uses six cameras positioned in six directions (up, down, left, right, front, and back) to identify the contents of the package. These cameras can scan all six sides of the package to find the matching tracking number. The barcode is then identified using a YOLO model, cropped out, and sent to ZXing for barcode recognition.

[0051] Then, based on the information of the region to which the express delivery belongs, it is transferred to the designated cargo box 34 at the end of the main transportation line 311.

[0052] Furthermore, a graded processing device is installed in front of the rapid identification zone 33 on the main transport line 311 to prevent express packages from being stacked or multiple packages from being passed side by side, thereby controlling the delivery of express packages one by one along the main transport line 311. The graded processing device mainly includes guide plates at different positions and angles. Using the guiding effect of these guide plates, abnormal express packages such as those that are stacked or placed side by side are separated and arranged in a row to pass through the subsequent identification area.

[0053] In this embodiment, the secondary transport line 312 is connected in parallel to one side of the main transport line 311. One end of it connects between the rapid identification area 33 and the cargo box 34, while the other end transports goods in the opposite direction to the main transport line 311. A rejection cargo box 34 is located at the end of the transport line to remove abnormal packages for manual inspection. For the specific transport route, please refer to [reference needed]. Figure 5 Hollow arrows indicate the path.

[0054] In this embodiment, the lower conveyor 32 is a roller conveyor, which is rectangular and surrounds the lower conveyor 31. It has several conveyor rollers inside that extend to the bottom of each cargo box 34 to move each cargo box 34 to a different position.

[0055] exist Figure 5 The lower conveyor 32, viewed from above, has a conveyor roller conveyor located above it, which is connected to the edge of the mobile hangar via an extension line 321 for docking with the lifting mechanism 61. The final path of each cargo box 34 on the lower conveyor 32 also converges onto the extension line 321. In addition to rejecting cargo boxes 34, the lower conveyor 32 also has an exit roller conveyor located away from the extension line 321 to reject the departure of cargo boxes 34.

[0056] After each cargo box 34 leaves the lower conveyor 32, a new cargo box 34 will enter the lower conveyor 32 via the conveyor roller and reach the replacement position.

[0057] The following is combined Figure 3 The specific structure of the maintenance unit 4 will be described below. In this embodiment, the elevator 41 is located at the opening edge of the U-shaped upper parking apron 1. The maintenance unit 4 includes a temporary storage area, an activity area, and a repair area. The temporary storage area is located at the edge of the mobile hangar on the side away from the sorting unit 3. The activity area is directly opposite the entrance of the elevator 41. See [link to relevant documentation]. Figure 3 The structure is arranged from top to bottom. Figure 3 The diagram shows three maintenance bays. The temporary storage area is equipped with a lateral movement track. After the drone moves from the second-floor platform to the next-floor activity area via elevator 41, it checks if there are any available maintenance bays. If not, it is placed in the temporary storage area. Drones that do not require maintenance or are in good working order are quickly moved to the lower parking apron 2 via the transport line.

[0058] The lower parking apron 2 consists of multiple units arranged in a spacious and unobstructed area, marked with parking signs. It is self-powered and can efficiently transport drones within a segment of the area after they are parked and no longer powered.

[0059] See Figure 3 and Figure 4 The battery swapping and storage warehouse 5 includes a battery swapping area and a storage area, which are located in the same factory building. A conveyor line is set between the two, and the lower parking apron 2 is located on one side of the conveyor line between the two.

[0060] The battery swapping area is designed to improve drone utilization, allowing drones that meet the battery swapping requirements to quickly recharge and enabling efficient drone scheduling. When a drone needs charging or swapping, it is transported from the mobile helipad to the battery swapping area. A multi-axis robotic arm removes the drone's battery and places it in the charging storage compartment, then inserts a fully charged battery into the drone.

[0061] The storage area is designed for high-density storage of drones to save floor space; it includes robotic arms and a drone bay. For example... Figure 4 As shown, the cabin consists of two rows with a robotic arm moving track in the middle. After the drone is transported to the vicinity of the robotic arm, the robotic arm transports the drone into the cabin to meet the high-density drone storage requirements.

[0062] The following is combined Figure 5 and Figure 6 Let's introduce the unmanned vehicle pickup unit 6. As an indispensable part of the implementation of this invention, the collaborative work of drones and unmanned vehicles, and the "air + ground" three-dimensional delivery system are realized through this part.

[0063] In this embodiment, the lifting mechanism 61 is vertically positioned on one side of the mobile hangar, with its top connected to the extension line 321 of the lower conveyor 32. A telescopic fork is mounted on the fork, which can move up and down with the vertical sliding frame of the lifting mechanism. The telescopic fork has multi-stage telescopic arms and can extend and retract horizontally for picking up and placing cargo boxes 34. First, the cargo box on the extension line 321 is gripped above the lifting mechanism 61, then retracted to the bottom of the lifting mechanism 61, and then extended in the opposite direction to place the cargo box 34 onto the unmanned vehicle. This completes the bulk transfer of express delivery from the air to the ground.

[0064] As the final link in the express delivery process, see Figures 7-9 The terminal docking unit 7 is generally located downstairs in each community or near residential areas, and includes a square box 71, to... Figure 7 For example, its interior front and rear sides are respectively equipped with express sorting components 74 and cargo storage components 75.

[0065] A telescopic guide groove 72 is provided on the front left side of the box body 71, above the feeding end of the express sorting component 74, for clamping the cargo box 34. In this embodiment, elastic pressure strips are provided around the telescopic guide groove 72, and a telescopic cylinder is provided at the rear to control the deformation of the elastic pressure strips, so as to enable the terminal to adapt to the size of the cargo box carried by different models of drones and meet the unloading requirements.

[0066] A rotating boom 73 is installed on the left outer wall of the container 71 to transfer the cargo box 34 from the unmanned vehicle to the telescopic guide slot 72. The rotating boom 73 is a high-strength, high-load linear module that drives the boom to move up and down. A crossbar is installed at the head of the boom for pushing and pulling. After the head of the boom docks with the cargo box on the unmanned vehicle, it is lifted to a suitable height by the linear module and then rotated to place the cargo box into the drone docking mechanism, completing the unloading of the package.

[0067] Of course, in addition to docking with the cargo box 34 of the unmanned vehicle, the infeed end of the express sorting component 74 can also dock directly with the cargo box 34 mounted under the drone to adapt to some areas that are not suitable for unmanned vehicles to pass through.

[0068] The express sorting component 74 is arranged horizontally. A large feed hopper is set at the inlet end, followed by a belt conveyor mechanism. Similar to the conveyor 31 above, the belt conveyor mechanism is equipped with a grading device and a rapid identification area. Expresses are unloaded from the hanger into the hopper, and the expresses are sorted by the conveyor belt. They pass through the six-sided identification area in a single row, and then stop at the last section of the conveyor belt to wait for subsequent actions to be completed.

[0069] The cargo storage component 75 is equipped with storage compartments of different sizes. The allocation of storage compartments for different express delivery devices is based on the size of the packages; for example, compartments smaller than 300 mm... 300 300mm small express delivery storage compartment.

[0070] A human-machine interface window is installed on the back wall of the cargo storage component 75. When a user arrives at the pickup point, they can enter their unique package pickup code through the external interactive screen. The system instantly verifies the pickup information, and the internal transportation device is then activated to accurately retrieve the corresponding package from the storage compartment. The package is then safely and smoothly transported to the user's pickup port via a conveyor mechanism, completing the entire pickup process.

[0071] Furthermore, the cargo storage component 75 uses a robotic arm to transport the express packages at the end of the express sorting component 74 to the storage compartment or pickup point. The control program of the robotic arm is set to store multiple express packages from the same person in the same storage compartment until the largest storage compartment can no longer hold the express packages, and then it will search for other storage compartments to store them.

[0072] This is a major inventive point of the present invention. The cargo storage component 75 includes a storage rack arranged opposite to the express sorting component 74, and a robotic arm between the storage rack and the express sorting component 74. The robotic arm consists of two parts: a Cartesian coordinate robotic arm and an end-effector bidirectional telescopic robotic arm. It can complete the process of transporting the goods from the end of the conveyor belt to the middle pallet, and then to the shelf or the picking port, thus completing the express storage and scheduling.

[0073] Because the cargo storage component 75 is equipped with storage compartments of different sizes, after sorting and classifying the goods in a cargo box, the robotic arm control system checks whether there are multiple packages for the same recipient in the cargo box. If so, based on the total space occupied by the multiple packages for the same recipient in the cargo box, the packages for the same recipient are grouped and stored in the same storage compartment. If the system determines that there is not a large enough storage compartment to accommodate multiple packages for the same recipient, it prioritizes storing them in the largest available storage compartment, and then searches for other one or more available storage compartments to store the remaining packages. Compared to the current method where recipients need to enter multiple pickup codes to open multiple cargo boxes, this saves both storage compartment space and pickup time.

[0074] Preferably, see Figure 9 As shown, a courier recycling bin is also provided on one side of the cargo storage component 75 for recycling empty cardboard boxes.
