Description

Technical Field

[0001] This invention belongs to the field of logistics and distribution technology, and in particular relates to an underground logistics and distribution terminal and system. Background Technology

[0002] In recent years, e-commerce has developed rapidly, especially in densely populated urban business districts with concentrated offices and businesses and high population density, resulting in a large and intense demand for commercial and personal express delivery. However, due to the lack of unified planning for the delivery system in these business districts and the absence of a systematic and effective management system, the organization of small-batch, high-frequency deliveries has led to a series of traffic and social environmental problems: small electric vehicles are inefficient in delivery, occupying urban traffic space, exacerbating traffic congestion, and increasing road safety hazards; large-item delivery vehicles are parked haphazardly, occupying public road space for sorting, causing significant social impact. Traditional delivery models are far from meeting the high-quality, high-positioning development requirements of current business districts and cannot satisfy the rapidly growing express delivery market demand in the future, necessitating innovation and transformation. Summary of the Invention

[0003] The purpose of this invention is to provide an underground logistics delivery terminal and system, which aims to solve the technical problems of traffic congestion, low efficiency and high safety hazards caused by the traditional delivery mode in the current business district.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] An underground logistics delivery terminal includes a building receiving room, a handling robot, a delivery robot, and multiple floor receiving points. The building receiving room is located in the underground parking garage level of a building and is used to connect with external large-item delivery vehicles and underground transport tracks. The handling robot can transport large packages unloaded from large-item delivery vehicles to smart self-service lockers. The transport tracks are connected to the building receiving room. The delivery robot is used to transfer standard delivery boxes containing small and medium-sized packages to the building receiving room, and to send empty boxes and pickup boxes in the building receiving room into the transport tracks. It also uses elevators to transfer standard delivery boxes to various floor receiving points.

[0006] Preferably, the transport track is suspended at the bottom of the building above the underground loop, and a vertical lift is provided at the edge of the transport track for lowering standard delivery boxes, lifting empty boxes and pickup boxes; the vertical lift works in conjunction with the delivery robot to complete the handover of standard boxes.

[0007] Preferably, the large-item delivery vehicle is an unmanned vehicle capable of traveling along the underground loop. Additionally, the handling robot is equipped with a robotic arm for carrying large packages.

[0008] Preferably, the smart self-service locker is equipped with an automatic loading device, which identifies large package information, places the package in the smart self-service locker, and sends the storage information to the recipient.

[0009] Preferably, the building's receiving and dispatching room includes a delivery vehicle unloading area, a handling robot passage area, a smart self-service locker area, a transport track and delivery robot connection area, a delivery robot passage area, and a robot charging area. External large-item delivery vehicles unload large packages in the delivery vehicle unloading area and hand them over to handling robots. The handling robots then transport the large packages to the smart self-service locker area via the handling robot passage area and store them in the smart self-service lockers. A primary track, a secondary track, a first handover station, and a second handover station are provided between the transport track and the delivery robot connection area. The primary track and the secondary track connect to the transport track. The system includes a vertical lifting machine located at the edge of the first and second tracks. The vertical lifting machine has four interfaces: a first interface and a fourth interface connecting to the first and second tracks, and a second interface and a third interface connecting to the first and second handover stations. The vertical lifting machine is used to lift standard boxes between the first and second tracks and the floor of the building's mailroom. A delivery robot along the delivery robot channel area transports standard boxes from the first handover station to the elevator and receiving points on each floor, and transfers empty boxes and parcel boxes from the elevator to the second handover station.

[0010] The first interface pushes the standard delivery box on the first track to the vertical lift. The second interface pushes the empty boxes and pickup boxes on the vertical lift to the second track. The third interface pushes the standard delivery box on the vertical lift to the handover station, and then pushes it to the delivery robot. The fourth interface pushes the empty boxes and pickup boxes that the delivery robot has transported to the handover station onto the vertical lift. The delivery robot then transfers the standard delivery box from the handover station to the building mailroom, and transfers the empty boxes and pickup boxes from the building mailroom to the handover station.

[0011] Preferably, the floor receiving point is equipped with a standard box receiving rack, which has multiple partitions for placing empty boxes and parcel boxes. The standard box receiving rack is equipped with a roller power device for handing over standard boxes to the delivery robot.

[0012] Preferably, the delivery robot is equipped with a double-layer roller four-compartment design for loading four standard boxes in two layers; the delivery robot is equipped with a microprocessor, a drive mechanism, and wheels at the bottom, and the drive mechanism drives the delivery robot to move in both directions and rotate 360 ​​degrees in place.

[0013] Preferably, the present invention also provides an underground logistics distribution system, including a joint distribution center, a transport track, and an underground logistics distribution terminal. The joint distribution center is used for the delivery and dispatch of small and medium-sized parcels. The transport track is set along the underground ring road of the city and suspended above the underground ring road. The standard box can run along the transport track and is used for delivering and picking up small and medium-sized parcels between the joint distribution center and the building receiving room of the building intelligent terminal.

[0014] Preferably, the joint distribution center includes a dispatch and unloading area, a sorting area, a delivery and loading area, a transport track connection area, a standard box temporary storage area, and a pickup and loading area. The dispatch and unloading area is used for unloading goods from logistics vehicles, the sorting area is used for sorting small and medium-sized packages, the delivery and loading area is used for loading the sorted small and medium-sized packages into standard boxes, the transport track connection area is used for connecting to the transport track, and the pickup and loading area is used for loading the collected small and medium-sized packages awaiting dispatch onto logistics vehicles.

[0015] Preferably, the transport track is provided with a fireproof isolation cover, and the standard box can run through the fireproof isolation cover.

[0016] Preferably, the transport track includes a main transport line, a secondary transport line, and branch transport lines. The main transport line is located at the top of the urban underground ring road and is arranged in two parallel lanes. The secondary transport lines are located at the top of the underground parking garage and are all connected to the main transport line. The branch transport lines are located between the secondary transport lines and each elevator.

[0017] The beneficial effects of adopting the above technical solution are as follows: Compared with the prior art, this invention, by setting up a building mailroom underground near the elevator, uses handling robots to transport large packages to intelligent self-service lockers, and delivery robots to transport small and medium-sized packages on the transport track to the building mailroom, which are then transported to receiving points on each floor via elevator. Simultaneously, empty boxes and parcel collection boxes from each floor's receiving points are transferred to the building mailroom and placed onto the transport track. This invention enables unmanned and contactless delivery, a crucial means to address the future surge in delivery demand, the increasing labor costs, and to reduce the social impact of logistics on transportation. Furthermore, by leveraging underground space development, a parcel delivery and collection system is established, enabling the delivery and collection of goods between the shared distribution center and the building mailroom, and between the building mailroom and each floor, ensuring that freight and passenger transport do not interfere with each other and improving operational efficiency. This invention can be flexibly designed according to the overall layout of underground space development, resulting in a highly efficient and automated system with strong future application scalability, playing a vital role in improving the overall transportation efficiency of urban last-mile delivery.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] In recent years, newly built urban business districts have generally carried out integrated development of underground space, with complete underground municipal facilities, underground road systems, and underground commercial spaces. At the same time, with the gradual maturity of intelligent equipment for last-mile delivery of logistics, it is possible to combine the underground integration of newly built business districts with the introduction of intelligent new technologies such as unmanned warehouses, autonomous driving, and intelligent self-pickup lockers to carry out intelligent underground logistics and establish intelligent underground logistics and delivery scenarios for the "last mile" delivery of urban express parcels.

[0035] See Figure 1This invention provides an underground logistics delivery terminal, comprising a building receiving room 100, a handling robot 12, a delivery robot, and multiple floor receiving points. The building receiving room 100 is located in the underground parking garage level of a building and is used to connect with external large-item delivery vehicles 10 and underground transport tracks 1. The handling robot 12 can transport large packages 11 unloaded from the large-item delivery vehicles 10 to smart self-service lockers 13. The transport tracks 1 are connected to the building receiving room 100. The delivery robots include a dispatch robot 8 and a standby delivery robot 9. The dispatch robot 8 is used to transfer standard delivery boxes 4 containing small and medium-sized packages transported by the transport tracks 1 to the building receiving room 100, and to send empty boxes 5 and pickup boxes 6 in the building receiving room into the transport tracks 1, and to transfer the standard delivery boxes 4 to various floor receiving points via elevators. The transport robot 12 is equipped with a robotic arm for handling large packages; the smart self-service locker 13 is equipped with an automatic loading device 14, which identifies large packages, places them in the locker, and sends the storage information to the recipient 15. Large packages are transferred to the smart self-service locker by the transport robot, awaiting pickup by the recipient. Small and medium-sized packages are bundled and delivered in standard boxes. All mail within the standard boxes is transported by delivery robots to receiving points on each floor, where recipients can retrieve their packages. The delivery robot then places the collected packages onto a transport track, which leads to a distribution center, where external logistics companies complete the shipping process.

[0036] In actual manufacturing, the compartments of the intelligent self-service locker 13 can be configured with different specifications and sizes according to actual needs. The locker is divided into front and rear ends. The recipient 15 retrieves the package at the front end of the locker, and the automatic loading device 14 automatically loads the package at the rear end. After recognizing the package information, the automatic loading device 14 places the package into a compartment of the locker and sends the package storage information to the user through the information system, reminding the recipient to pick up the package. The automatic loading device here is existing technology and has the same structure as an autonomous forklift, so it will not be described in detail here.

[0037] To further optimize the above technical solution, the large-item delivery vehicle 10 is an unmanned vehicle capable of traveling along an underground loop. Large packages are transported using unmanned vehicles; small and medium-sized packages, which account for approximately 85% of all express parcels, are transported via rail, thus improving delivery efficiency.

[0038] As a preferred structure, such as Figure 3 , 4As shown, the transport track 1 is suspended at the bottom of the building above the underground loop. A vertical lift 7 is installed at the edge of the transport track 1 to lower standard delivery boxes 4 and lift empty boxes 5 and pickup boxes 6. The vertical lift 7 works in conjunction with the delivery robot to complete the handover of standard boxes. The transport track adopts a suspended transport method and is located on the top floor of the garage. The vertical lift enables the three-dimensional spatial transfer of standard boxes between the suspended track and the delivery robot. The delivery robot and the vertical lift can automatically exchange items. The delivery robot is a current technology, also known as an autonomous driving robot, and is currently widely used in hotels and shopping malls. The vertical lift is similar to a freight elevator, enabling the vertical transport of goods.

[0039] In one specific embodiment of the present invention, such as Figure 1-4 As shown, the building's receiving and dispatching room 100 includes a delivery vehicle unloading area 101, a handling robot passage area 102, a smart self-service locker area 103, a transport track and delivery robot connection area 104, a delivery robot passage area 105, and a robot charging area 106. External large-item delivery vehicles 10 unload large packages 11 in the delivery vehicle unloading area 101 and hand them over to handling robots 12. The handling robots 12 then transport the large packages 11 through the handling robot passage area 102 to the smart self-service locker area 103 and store them in the smart self-service locker 13. The transport track and delivery robot connection area 104 includes a first track 2, a second track 3, a first handover station 22, and a second handover station 23. The first track 2 and the second track 3... The vertical lift 7 connects the transport track 1 and the vertical lift 7, which is located at the edge of the first track 2 and the second track 3. The vertical lift 7 has four interfaces: a first interface 19 and a fourth interface 18 that connect to the first track 2 and the second track 3, a second interface 20 and a third interface 21 that connect to the first handover station 22 and the second handover station 23. The vertical lift 7 is used to lift standard boxes between the first track 2 and the second track 3 and the ground of the building's mailroom 100. The delivery robot 8 transports the standard delivery box 4 from the first handover station 22 to the elevator 16 and the receiving points on each floor along the delivery robot channel area 105, and transfers the empty box 5 and the package box 6 from the elevator 16 to the second handover station 23.

[0040] At the first interface 19, the standard delivery box 4 on the first track 2 is pushed onto the vertical lift 7. At the second interface 20, the standard delivery box 4 on the vertical lift 7 is pushed to the first handover station 22 and then onto the waiting delivery robot 9. At the third interface 21, the empty box 5 and the pickup box 6, which are transported by the delivery robot to the second handover station 23, are pushed onto the vertical lift 7. At the fourth interface 18, the empty box 5 and the pickup box 6 on the vertical lift 7 are pushed onto the second track 3. The delivery robot 8 then transfers the standard delivery box 4 from the first handover station 22 to the elevator 16 entrance, and transfers the empty box 5 and the pickup box 6 from the elevator 16 entrance to the second handover station 23.

[0041] In one specific embodiment of the present invention, such as Figure 5 As shown, the floor receiving point is equipped with a standard box receiving rack 17. The standard box receiving rack 17 has multiple partitions for placing empty boxes 5 and parcel boxes 6. The standard box receiving rack 17 contains a roller power unit for handing over standard boxes to the delivery robot. The delivery robot has a double-layer roller four-compartment design. The roller power unit can pull out the standard boxes placed in the double-layer roller four-compartment design using a robotic arm. The robotic arm is also existing technology and will not be described in detail here. The double-layer roller four-compartment design allows for the transport of four standard boxes at a time. The delivery robot has a microprocessor, a drive mechanism, and wheels at the bottom. The drive mechanism drives the delivery robot to move bidirectionally and rotate 360 ​​degrees in place; this is existing technology and will not be described in detail here. To improve the robot's walking efficiency and safety, dedicated robot passages are provided in elevators and on each floor of the building. The delivery robot is also wirelessly connected to the operation platform, allowing staff to remotely control the delivery robot and obtain delivery information from the operation platform.

[0042] In the specific design, each layer of the delivery robot and the standard box receiving rack corresponds to each other, and each layer is equipped with a roller power device, which enables the transfer of standard boxes between the delivery robot and the standard box receiving rack.

[0043] This invention also provides an underground logistics distribution system, such as... Figure 6 As shown, the system includes a joint distribution center 200, a transport track 1, and an underground logistics delivery terminal. The joint distribution center 201 is used for the delivery and dispatch of small and medium-sized parcels. The transport track 1 is set along the underground ring road of the city and suspended above the underground ring road. The standard box can run along the transport track 1 and is used to deliver and pick up small and medium-sized parcels between the joint distribution center 200 and the building receiving room 100 of the building intelligent terminal.

[0044] The standard container's dimensions can be designed according to the specifications of the transport track. It can be directly loaded onto transport tracks, logistics vehicles, and delivery robots. The standard container features an RFID tag 24 on its bottom and a barcode 25 on its side for positioning and tracking. The standard container's appearance can be customized to meet specific project requirements, such as aesthetic enhancements. Figure 8 , 9 As shown. Standard containers of uniform specifications are used, which facilitates mass production and stacking, and modular operation enables rapid loading and unloading.

[0045] To enhance the system's intelligence, the delivery system, in its implementation, relies on an operating platform. Detachable conveyor mechanisms are installed on standard containers, or drive mechanisms are installed on transport tracks. The operating platform, through software algorithms, triggers the movement of these hardware devices, controlling the actions of the conveyor or drive mechanisms to achieve automated cargo transport. This, together with the transport tracks, forms an underground intelligent transportation system. Simultaneously, this underground intelligent transportation system, in collaboration with a shared distribution center, intelligent terminal units in buildings, and the operating platform, forms a smart, integrated, standardized, and platform-based "four-in-one" express delivery and pickup system. This solution addresses the urban traffic and environmental problems associated with traditional delivery systems, achieving the goal of reducing logistics costs and increasing efficiency.

[0046] In one specific embodiment of the present invention, the joint distribution center 200 includes a delivery unloading area, a sorting area, a delivery loading area, a transport track connection area, a standard box temporary storage area, and a pickup loading area. The delivery unloading area is used for unloading goods from logistics vehicles 201. The sorting area is used for sorting small and medium-sized parcels. The delivery loading area is used for loading the sorted small and medium-sized parcels into standard boxes. The transport track connection area is used for connecting to transport track 1. The pickup loading area is used for loading collected small and medium-sized parcels awaiting dispatch onto logistics vehicles 201. The joint distribution center serves as a transit node for express parcels entering and leaving the business district. The location of the joint distribution center should consider its connection with internal and external transportation, ensuring convenient access for external logistics vehicles, reducing internal delivery detours, and minimizing traffic impact. The joint distribution center can be integrated with public spaces in the urban business district (such as spaces beneath green spaces), public parking lots, and municipal supporting facilities. Given that newly built urban business districts generally involve integrated development of underground space, and the functions of underground commercial facilities, municipal infrastructure, and transportation are constantly being improved, the joint distribution center can be located underground, on the same level as the underground ring road system.

[0047] When delivering packages at the joint distribution center, external logistics vehicle 201 unloads all express goods destined for the area in the delivery unloading area. The goods are then re-sorted in the sorting area according to their destination and size, standardized in loading and combining, and optimized in terms of delivery plan. After sorting, they are loaded into standard boxes in the delivery loading area. These standard delivery boxes 4 are then delivered to their respective destinations within the area via the underground intelligent transportation system. Collection boxes 6 and returned empty boxes 5 are transported to the collection loading area via the underground intelligent transportation system, where they are loaded onto logistics vehicles for dispatch. Figure 6 As shown.

[0048] As a preferred option, such as Figure 7 As shown, the transport track 1 includes a main loop transport line 107, a secondary transport line 108, and a branch transport line 109. The main transport line 107 is located at the top of the urban underground loop and is arranged in a double-track configuration. The secondary transport lines 108 are located at the top of the underground parking garage and connect to the main transport line 107. The branch transport lines 109 are located between the secondary transport lines 108 and each elevator 16. Utilizing the transport track that efficiently connects different plots of land in the area, a three-level vehicular system of "underground main loop – underground connecting secondary roads – underground parking garage" is formed. The standard box transport track system, considering the characteristics of underground roads and underground parking garages, sets up the main transport line at the top of the underground loop and the secondary transport line at the top of the underground parking garage, connecting to the main loop transport line, without affecting the underground road clearance or the clear height of the underground parking garage. Based on the characteristics of the underground loop and underground parking garage, the main and secondary transport lines adopt a double-track parallel loop design.

[0049] Standard containers travel along transport track 1, which connects the shared distribution center 200 to various building destinations, enabling them to be dispatched immediately upon arrival and for rapid turnover. The automated transport of standard containers is controlled by an operations platform, resulting in a high degree of automation. Simultaneously, scanning devices that read electronic chips are installed on the transport track to automatically identify the destination of the standard containers. The operations platform's scheduling system then automatically allocates and transports the standard containers to their destination stations along the transport track.

[0050] To further optimize the above technical solution, a fireproof isolation cover (not shown in the figure) is provided on the outside of the transport track 1, and the standard box can run through the fireproof isolation cover. The fireproof isolation cover is made of civil engineering materials, which can ensure safety and appearance requirements.

[0051] In one specific embodiment of the present invention, such as Figure 6 , 7As shown, the intelligent building terminal includes a building mailroom 100 and a delivery robot. The building mailroom 100 is located near the elevator 16 and can connect to the secondary delivery line 108 and the branch delivery line 109. The delivery robot is equipped with a camera for scanning the electronic tags 24 on standard boxes, and can deliver goods to the floors where the recipients are located. The intelligent building terminal serves all high-rise buildings 300 in the area, is located in the underground parking garage of each building, connects to the underground intelligent transportation system, and completes floor-to-floor delivery within the building. The building mailroom 100 is located near the core elevator 16, and floor-to-floor delivery within the building is completed by the delivery robot.

[0052] The delivery robot transports standard delivery boxes 4, pickup boxes 6, and empty boxes 5 between the building's mailroom 100 and the floor receiving points. The robot's movement within the building includes the mailroom, the area from the mailroom to the freight elevator, and the area from the freight elevator to each floor's receiving point. To improve the robot's efficiency and safety, an optimized dedicated path is provided. The delivery robot interacts with the elevator, automatically entering and reaching the designated floor to complete the delivery task. During idle periods, the robot recharges in the building's mailroom charging area and remains ready for further use. These are all existing technologies with similar applications in hotels and other locations, used for delivering water, food, etc.

[0053] Given the stringent fire safety requirements for underground transportation equipment and passageways, the entire system is equipped with fire detection. Smoke detectors, temperature sensors, and fire-resistant roller shutters (not shown in the diagram) are installed in the joint distribution center 200, transport track 1, and building receiving and dispatching room 100. The smoke and temperature sensors detect abnormal situations and trigger alarms. The fire-resistant roller shutters are located at the exits of the transport track and the entrances and exits of the joint distribution center and building receiving and dispatching room. Additionally, smoke detectors, temperature sensors, and fire-resistant roller shutters can be installed on the inner walls of the fireproof enclosure. These detectors can be connected to the operations platform; upon detecting an anomaly, an alarm will automatically sound, the fire-resistant roller shutters will be quickly lowered, all goods will be evacuated, and other systems will be notified, achieving coordinated control.

[0054] The operation platform integrates hardware management and monitoring, information management and monitoring, relevant operator information sharing systems, and customer terminal information management systems. Through the operation platform's supervision, information sharing, and coordinated interaction, the system effectively ensures and monitors the efficient operation of the lines.

[0055] like Figure 10 As shown, the process of dispatching and picking up packages using this invention is as follows:

[0056] Large logistics vehicles 201 transport express parcels to the joint distribution center 200. The joint distribution center 200 can utilize highly automated sorting equipment, such as cross-belt sorters or robotic sorting systems. An unloading platform is set up in the external delivery and unloading area of ​​the joint distribution center. This platform connects to the loading station in the sorting area via a conveyor belt. The loading station performs security checks, barcode scanning, and weighing on all express parcels unloaded from the delivery and unloading area, before handing them over to automated robots for sorting and consolidation. The parcels are then placed into standard boxes. All parcels within the same standard box are destined for the same building floor.

[0057] In the transport track connection area of ​​the joint distribution center 200, standard containers are scanned using scanning equipment to determine their destination. The conveyor mechanism driving the standard containers can automatically plan its travel path based on the information stored inside. The standard containers are then transported along transport track 1 at the top via a vertical lift. Figure 7 As shown, the standard container is transported via the underground loop main transport line 107, connected to the secondary transport line 108 entering the underground garage, and then connected to the branch transport line 109 to enter the building receiving room 100 on the ground floor of the target building.

[0058] In the building's ground floor receiving and dispatching room 100, standard containers are lowered from the top transport track 1 to the ground floor operating level of the receiving and dispatching room by a vertical lift. Figure 1 The smart station automatically hands over standard parcel lockers to delivery robots. Some parcels enter the smart self-service locker area. The front and back ends of the smart self-service locker area have different functions: the front is the user pickup door, and the back is the automatic loading door (smart self-service lockers are existing technology and will not be described in detail here). The automatic loading device at the back identifies the parcel and places it in, then sends the parcel storage information to the user's terminal through the information system, reminding the user to pick up the parcel.

[0059] Standard boxes requiring floor-to-floor delivery are handled by delivery robots. The delivery robot travels through a dedicated passageway in the building's mailroom 100 to the designated elevator 16. The robot communicates with the elevator 16 via an information interaction system, then takes the elevator to the designated receiving point on the target floor, automatically delivering the standard box to the standard box receiving rack 17. Each floor's standard box receiving rack 17 is an automated shelf equipped with a roller-driven mechanism, enabling automatic exchange of standard boxes with the mobile robot. After the exchange is complete, the operations platform sends the delivery information via an electronic tag and notifies the recipient to pick up the package at the designated location.

[0060] The sender places an order in the courier system, packages and labels the parcel according to standard procedures, and then delivers the parcel to the designated standard box at the standard box receiving rack. After completing the standard box delivery process, the delivery robot retrieves the parcel collection box 6 and the empty box 5, enters elevator 16 via a designated route, and returns to the building's mailroom 100.

[0061] The delivery robot hands over the parcel box 6 and empty box 5 to the vertical lift at the automated interactive station, where they enter the top transport track.

[0062] 1. First, the standard container enters the underground parking garage branch conveyor line 109, then enters the main conveyor line 107 of the underground loop via the secondary conveyor line 108. After arriving at the joint distribution center 200, the standard container is delivered to the ground operation level of the joint distribution center 200 via a vertical elevator. Empty container 5 enters the dispatch process to begin the next round of delivery operations, while pickup container 6 enters the pickup, sorting, and packaging process. All completed pickups are handed over to the respective external logistics vehicles at a unified time.

[0063] In summary, this invention establishes a building mailroom near the elevators in the underground area. Large packages are moved to smart self-service lockers by transport robots, while smaller packages transported by rail are moved to the building mailroom by delivery robots and then transported to receiving points on each floor via elevator. Simultaneously, empty boxes and parcel collection boxes from each floor are transferred to the building mailroom and placed onto the rails. This invention enables unmanned and contactless delivery, a crucial means to address the future surge in delivery demand, the increasing labor costs, and to reduce the social impact of logistics on transportation. Furthermore, leveraging underground space development, it establishes a parcel delivery and collection system, enabling the delivery and collection of goods between the shared distribution center and the building mailroom, and between the building mailroom and each floor. This ensures that freight and passenger transport do not interfere with each other, improving operational efficiency. This invention can be flexibly designed according to the overall layout of underground space development, boasting high system efficiency, a high degree of automation, and strong scalability for future applications. It plays a vital role in improving the overall transportation efficiency, including last-mile delivery in cities.
