Description

Technical Field

[0001] This application relates to the field of automobile manufacturing technology, and in particular to a logistics trolley and logistics transportation device. Background Technology

[0002] Automated Guided Vehicles (AGVs) are transport vehicles equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guidance path, and possessing safety protection and various transfer functions. AGVs are a special application of wheeled mobile robots, offering advantages over walking, crawling, or other non-wheeled mobile robots, including faster movement, higher work efficiency, simpler structure, stronger controllability, and better safety. Compared to other equipment commonly used in material handling, AGVs do not require fixed devices such as tracks or support frames, and are not limited by site, road, or space constraints. Therefore, in intelligent logistics systems, their automation and flexibility are most fully realized, achieving efficient, economical, and flexible unmanned logistics.

[0003] With the development of intelligent logistics, more and more AGVs are being used in factory logistics applications. Existing lifting AGVs require the attachment of cargo codes to the bottom of the trolley for AGV docking. The most common methods for attaching these codes are: for example, tilting the trolley upside down and attaching the codes to the bottom; or having the operator crawl under the trolley to attach the codes. These methods require operators to frequently tilt the trolley down and bend over to attach the codes, or crawl under the trolley to attach them, during the debugging process. Furthermore, it is difficult to control the positioning accuracy of the codes, leading to a prolonged debugging cycle. Utility Model Content

[0004] This application discloses a logistics trolley and a logistics transportation device, which improves the positional accuracy of the cargo code by removing the cargo code module from the vehicle body and then pasting the cargo code.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] In a first aspect, embodiments of this application provide a logistics trolley, including a vehicle body and a cargo code module;

[0007] The vehicle body includes a main frame and at least one layer plate fixed to the main frame, the at least one layer plate including a bottom plate;

[0008] The cargo code module includes an installation part and a docking part; the installation part is detachably connected to the base plate, and the docking part penetrates the base plate; the surface of the docking part away from the installation part is used to adhere the cargo code for docking with external equipment.

[0009] The aforementioned logistics trolley modularizes the code module and detachably installs it on the vehicle body. When it is necessary to affix the code, the code module is removed from the vehicle body, facilitating the affixing of the code and improving the positional accuracy of the code affixing. Specifically, the vehicle body includes a main frame and at least one shelf fixed to the main frame. Among the at least one shelf, the shelf located at the bottom of the vehicle body is the base plate. The code module is detachably installed on the base plate, facilitating docking between the code module and external equipment such as automated guided vehicles (AGVs). To facilitate the installation of the code module, the code module includes a mounting part and a docking part. The mounting part is fixed to the base plate, and the docking part penetrates the base plate to expose the code affixed thereon. External equipment such as AGVs move under the base plate and recognize the code on the docking part to complete the docking. In the logistics trolley provided in this application embodiment, the code module is independent of the vehicle body. When affixing the code, it is not necessary to tip the trolley over or crawl under the trolley; simply remove the code module from the base plate to affix the code. In practice, multiple cargo code modules can be removed from their respective vehicle bodies and placed on a workbench for batch pasting of cargo codes. This facilitates personnel operation. At the same time, other tools such as rulers and laser pointers can be used to assist in pasting cargo codes, which greatly improves the positional accuracy of the cargo code pasting and avoids docking failures and repeated pasting of cargo codes caused by low positional accuracy of cargo code pasting.

Detailed Implementation

[0044] First, let me introduce the application scenario of this application: In traditional lifting AGVs, the cargo codes that dock with the lifting AGV are affixed to the bottom plate of the trolley. During docking, the lifting AGV moves to the bottom plate of the trolley, the scanning unit on top of the lifting AGV scans the cargo codes on the bottom plate to achieve docking, and then the lifting mechanism of the lifting AGV supports the bottom plate to lift the trolley and transport it to the preset position. When affixing cargo codes, the trolley is usually tilted over to affix the codes, or the operator crawls under the trolley to affix the codes. These methods are not easy to control the positional accuracy of the cargo codes, resulting in extended cycle time.

[0045] Based on the above application scenarios, this application provides a logistics trolley and a logistics transportation device, which improves the positional accuracy of the cargo code by pasting the cargo code after removing the cargo code module from the vehicle body.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In the description of the embodiments of this application, unless otherwise stated, " / " means "or", for example, A / B can mean A or B; "and / or" in the text is merely a description of the relationship between related objects, indicating that there can be three relationships, for example, A and / or B can represent: A alone, A and B at the same time, and B alone. In addition, in the description of the embodiments of this application, "multiple" means two or more.

[0047] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0048] like Figures 1 to 4 As shown, this application embodiment provides a logistics trolley, including a vehicle body 100 and a cargo code module 200;

[0049] The vehicle body 100 includes a main frame 110 and at least one shelf 120 fixed to the main frame 110, the at least one shelf 120 including a bottom plate 121;

[0050] The code module 200 includes an installation part 210 and a docking part 220; the installation part 210 is detachably connected to the base plate 121, and the docking part 220 penetrates the base plate 121; the surface of the docking part 220 away from the installation part 210 is used to adhere the code for docking with external equipment.

[0051] The aforementioned logistics trolley modularizes the barcode module 200 and detachably mounts it onto the vehicle body 100. When barcodes need to be affixed, the barcode module 200 is removed from the vehicle body 100, facilitating barcode application and improving barcode positioning accuracy. The barcode can be a barcode or QR code, etc. Specifically, the vehicle body 100 includes a main frame 110 and at least one shelf 120 fixed to the main frame 110. Of the at least one shelf 120, the shelf 120 located at the bottom of the vehicle body 100 is a base plate 121. The barcode module 200 is detachably mounted on the base plate 121, facilitating information exchange between the barcode module 200 and external equipment such as automated guided vehicles (AGVs). To facilitate the installation of the code module 200, the code module 200 includes a mounting part 210 and a docking part 220. The mounting part 210 is fixed to the base plate 121, and the docking part 220 penetrates the base plate 121 to expose the code pasted thereon. External equipment, such as automated guided vehicles, moves to the bottom of the base plate 121 and identifies the code on the docking part 220 to complete information docking. In the logistics trolley provided in this embodiment, the code module 200 is independent of the vehicle body 100. When pasting the code, there is no need to tip the trolley over or crawl under the trolley; the code module 200 only needs to be removed from the base plate 121 to paste the code. In specific implementation, multiple code modules 200 can be removed from their respective vehicle bodies 100 and placed on a workbench to achieve batch pasting of the code, which is convenient for personnel operation. At the same time, other tools such as rulers and laser pointers can be used to assist in pasting the code, which greatly improves the positional accuracy of the code and avoids information docking failure and repeated pasting of code due to low positional accuracy of the code, thus greatly improving the implementation efficiency of the docking equipment.

[0052] In some embodiments, the base plate 121 includes a bearing surface 1211 for bearing materials; the mounting part 210 is detachably connected to the bearing surface 1211.

[0053] like Figure 3 and Figure 4 As shown, the cargo code module 200 adopts a modular design, allowing for independent disassembly and installation on the vehicle body 100. This design enables the cargo code module 200 to operate independently, facilitating maintenance, replacement, and batch operation. The cargo code module 200 includes a mounting part 210 and a docking part 220. The mounting part 210 is fixed to the bearing surface of the base plate 121, while the docking part 220 penetrates the base plate 121 to expose the cargo code, ensuring its visibility and facilitating identification and information integration by external equipment such as automated guided vehicles.

[0054] The mounting part 210 is fixed to the bearing surface 1211 by a detachable connection method, such as snap-fit, threaded connection, or magnetic attraction, which facilitates quick disassembly and reinstallation and improves operational efficiency. In specific implementations, for example, the mounting part 210 is fixed with bolts and includes bolt holes. Alternatively, the mounting part 210 is fixed with snap-fit ​​and includes a locking block. Or, the mounting part 210 is fixed with magnetic attraction and includes a magnetic component.

[0055] In one implementation, a mounting groove penetrating the base plate 121 is provided, and the cargo module 200 is accommodated in the mounting groove. The mounting part 210 overlaps the bearing surface 1211 of the base plate 121, and the mounting part 210 is locked to the base plate 121 by bolts.

[0056] In some embodiments, the mounting portion 210 includes an annular plate 211 surrounding the outside of the docking portion 220. The annular plate 211 has structures such as screw holes, snap-fits, and limiting grooves for detachable connection with the base plate 121, enabling the code module 200 to be quickly and securely installed and removed. The annular plate 211 also facilitates the removal of the code module 200. When the code module 200 is removed from the base plate 121, the annular plate 211 surrounds the outside of the docking portion 220 and protrudes from the bearing surface 1211, allowing the code module 200 to be easily removed by picking up the annular plate 211.

[0057] In one implementation, such as Figure 3 and Figure 4 As shown, the annular plate 211 has fixing holes 212. The cargo stacking module 200 is fixed to the base plate 121 by bolts. The bolts pass through the fixing holes 212 and are threadedly connected to the base plate 121.

[0058] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the transport vehicle 500 moves to the bottom plate 121 and scans the cargo code on the cargo code module 200 to complete the information docking. After the transport vehicle 500 completes the information docking, some structures such as the lifting platform rise and support the bottom plate 121 to lift the entire trolley, realizing automatic navigation and classification based on the information on the cargo code.

[0059] It should be noted that, Figure 3 and Figure 4 The docking part 220 of the code module 200 shown is a cube, but the docking part 220 can also be other shapes, such as a cuboid or a cylinder.

[0060] However, in the factory logistics environment, there are seams on the road surface. When the transport vehicle 500 passes through, it will vibrate. The trolley will deviate slightly due to the vibration, which will cause the transport vehicle 500 to fail to calibrate the cargo and thus be unable to continue to perform the task, requiring manual intervention.

[0061] Based on this, in some embodiments of this application, such as Figure 7 As shown, a ring-shaped limiting structure 300 is provided on the side of the base plate 121 away from the bearing surface. The ring-shaped limiting structure 300 includes multiple limiting strips 310. The limiting strips 310 are fixed to the base plate 121, and the multiple limiting strips 310 are arranged in a ring to form a limiting space.

[0062] The ring-shaped limiting structure 300 is an auxiliary structure used for positioning. For example... Figure 7 As shown, the annular limiting structure 300 is composed of multiple limiting strips 310. The limiting strips 310 are fixed to the base plate 121 and arranged in a ring to form a limiting space for positioning of some structures of the transport vehicle 500, such as the lifting platform.

[0063] The limiting space is used to accommodate some structures of the transport vehicle 500, such as the lifting platform of the transport vehicle 500, thereby ensuring the docking accuracy and stability between the transport vehicle 500 and the base plate 121. The design of the limiting space also prevents the trolley from shifting relative to the transport vehicle 500 during use.

[0064] The shape and size of the limiting space formed by the cooperation of all the limiting strips 310 can be designed to match the docking structure of the transport vehicle 500 to achieve rapid positioning and limiting.

[0065] The logistics trolley provided in this embodiment forms a limiting space on the base plate 121. The transport vehicle 500 can be mechanically docked and limited with the limiting space, which avoids the logistics trolley from shifting relative to the transport vehicle 500 due to the vibration of the transport vehicle 500 during the movement of the transport vehicle 500. This ensures the relative position stability between the transport vehicle 500 and the logistics trolley, and avoids the transport vehicle 500 failing to calibrate the cargo pack, which would prevent it from being unable to continue performing the task.

[0066] In some embodiments, such as Figure 8 As shown, the limiting strip 310 includes a fixing part 311 and a guiding part 312; the fixing part 311 is fixed to the base plate 121, and the guiding part 312 is provided with a guiding surface 3121 on the side facing the limiting space; along the bearing surface to the limiting strip 310 direction, the guiding surface 3121 is inclined away from the limiting space.

[0067] like Figure 8 As shown, the limiting strip 310 includes a fixing part 311 and a guiding part 312. The fixing part 311 is responsible for stable connection, and the guiding part 312 is responsible for guiding the docking of the transport vehicle 500. For example, the limiting strip 310 is a rigid component. The fixing part 311 is fixed to the base plate 121 to ensure the stability of the entire limiting strip 310 structure; the guiding part 312 is provided with a guide surface 3121 facing the limiting space to assist the docking of the vehicle body 100 and the transport vehicle 500.

[0068] The guide surface 3121 is inclined away from the limiting space along the direction from the bearing surface to the limiting strip 310. This is an outwardly expanding inclined structure, the main function of which is to guide part of the transport vehicle 500 smoothly into the limiting space, which can effectively reduce the difficulty of aligning the transport vehicle 500 during lifting.

[0069] The design of the guide surface 3121 enables the transport vehicle 500 to automatically adjust its position and enter the limit space during the mechanical docking process with the logistics trolley, even if there is a slight deviation. This achieves self-alignment docking, significantly improving the fault tolerance of mechanical docking and reducing the difficulty of operation.

[0070] In some factory scenarios, 500 transport vehicles are needed to deliver materials and manual delivery of auxiliary tools at the same time, which leads to problems of operational waste and route conflicts.

[0071] In one implementation, the main frame 110 is made of welded square tubing, which can be made of carbon steel or other metals. The base plate 121 includes a plate body and a bottom frame. The plate body is made of carbon steel, and the bottom frame is made of welded square tubing, which can be made of carbon steel or other metals. A mounting slot for installing the code module 200 is provided at the center of the base plate 121. The code module 200 is inserted into the mounting slot, and the height of the end face of the code needs to match the focal length of the scanning part (e.g., camera) on the top of the transport vehicle 500; the end face size is slightly larger than the code label size. Pin holes are provided on the annular plate 211 of the code module 200, and pins are installed on the base plate 121 to fix the code module 200 to the pin holes. The code module 200 can be directly removed for operation when pasting or adjusting the code. Four limiting strips 310 are installed at the bottom of the base plate 121, forming a limiting space. The limiting strip 310 is fixed to the bottom frame with bolts, allowing the lifting platform of the transport vehicle 500 to accurately engage within the limiting space. Thus, the top camera of the transport vehicle 500 can be aligned with the center of the cargo stack on the base plate 121 while traveling on various road conditions.

[0072] Based on this, in some embodiments of this application, the logistics trolley also includes a mounting pallet 400, which is mounted on the main frame 110.

[0073] like Figure 1 and Figure 2 As shown, the logistics trolley is equipped with a mounting pallet 400, which is used to carry goods, tools, or other equipment and is a key load-bearing component in logistics transportation. The mounting pallet 400 is attached to the main frame 110 for easy and quick installation and replacement.

[0074] In one implementation, the main frame 110 is equipped with a hooking structure adapted to the hooking pallet 400, ensuring that the hooking pallet 400 can be stably fixed on the trolley, preventing shaking or falling off during transportation. The detachable design of the hooking pallet 400 makes the transportation of auxiliary tooling more convenient, improves the transportation efficiency of the logistics trolley, and avoids the need for manual delivery of auxiliary tooling.

[0075] The logistics trolley is equipped with fixed outriggers 130. When the transport vehicle 500 is running, the fixed outriggers 130 will block the obstacle detection range, which poses a safety hazard.

[0076] Based on this, in some embodiments of this application, the vehicle body 100 further includes a plurality of outriggers 130; the outriggers 130 have a first station and a second station relative to the base plate 121;

[0077] When the outrigger 130 is in the first position, the outrigger 130 protrudes from the bottom plate 121 on the side away from the bearing surface to support the vehicle body 100.

[0078] When the outrigger 130 is in the second position, the outrigger 130 does not protrude from the side of the base plate 121 away from the bearing surface, so as to avoid the outrigger 130 affecting the obstacle detection range of the transport vehicle 500.

[0079] The aforementioned support leg 130 has multiple options when switching between the first and second workstations. For example, the angle between the support leg 130 and the base plate 121 can be changed by rotating relative to the main frame 110. Alternatively, the position between the support leg 130 and the base plate 121 can be changed by extending or retracting relative to the main frame 110.

[0080] In some embodiments of this application, such as Figure 9 and Figure 10 As shown, the vehicle body 100 also includes multiple outriggers 130; multiple connectors 131 are provided on the side of the main frame 110 near the bottom plate 121; one connector 131 is detachably connected to one outrigger 130 via a pin 132; a first pin hole is provided on the connector 131;

[0081] The outrigger 130 is provided with a second pin hole and a third pin hole, and the axis of the second pin hole is perpendicular to the axis of the third pin hole.

[0082] When the pin 132 passes through the first pin hole and the second pin hole, the outrigger 130 is perpendicular to the base plate 121 to support the vehicle body 100.

[0083] When the pin 132 passes through the first pin hole and the third pin hole, the support leg 130 is parallel to the base plate 121.

[0084] like Figure 9 and Figure 10As shown, the vehicle body 100 is equipped with multiple outriggers 130 to support the entire logistics trolley, ensuring its stability and load-bearing capacity when stationary. The outriggers 130 are detachably connected to the main frame 110 via connectors 131 and pins 132, facilitating quick installation, disassembly, and replacement. Specifically, the main frame 110 has connectors 131 on the side near the base plate 121 that correspond one-to-one with the outriggers 130, and the connectors 131 are connected to the outriggers 130 via pins 132.

[0085] In specific implementation, the connector 131 is provided with a first pin hole, the axis of which is perpendicular to the base plate 121; the support leg 130 is provided with a second pin hole and a third pin hole, the axis of which is parallel to the extension direction of the support leg 130, and the axis of which is perpendicular to the extension direction of the support leg 130. When the pin shaft 132 connects the first pin hole and the second pin hole, the support leg 130 is fixed to the connector 131 and is in the first position, at which time the support leg 130 is perpendicular to the base plate 121. When the pin shaft 132 connects the first pin hole and the third pin hole, the support leg 130 is fixed to the connector 131 and is in the second position, at which time the support leg 130 is parallel to the base plate 121.

[0086] In practice, the outrigger 130 is perpendicular to the base plate 121 to support the entire logistics trolley. When the transport vehicle 500 lifts the entire logistics trolley, the pin 132 can be pulled out to unlock the outrigger 130 and the connector 131. The outrigger 130 is then removed from the connector 131 and rotated 90°. At this point, the outrigger 130 is parallel to the base plate 121. When the third pin hole coincides with the axis of the first pin hole, the pin 132 is inserted to lock the outrigger 130 and the connector 131, so that the outrigger 130 does not affect the obstacle detection range of the transport vehicle 500.

[0087] In one implementation, such as Figure 11As shown, connector 131 is a cuboid and is installed on the main frame 110 by welding with a mounting plate. Support legs 130 are nested onto connector 131 via docking frames 1301. Both docking frames 1301 and connector 131 have pin holes 135 at their centers on all four sides. The pin hole 135 at the top of connector 131 is the first pin hole, the pin hole 135 at the top of docking frame 1301 is the second pin hole, and the pin hole on the left or right side of docking frame 1301 is the third pin hole. The support legs 130 are fixedly locked to the main frame 110 by inserting quick-release pins 132 into the pin holes 135 on connector 131 and docking frame 1301. When it is necessary to rotate the support leg 130, first remove the pin 132 and pull out the docking frame 1301. At this time, with the support leg 130 in a parallel position to the base plate 121, the docking frame 1301 can be nested and installed on the connector 131 to achieve angle adjustment of the support leg 130 relative to the base plate 121. To increase the docking angle between the support leg 130 and the connector 131, the docking frame 1301 and the connector 131 can be other multi-faceted column structures, such as hexagonal column structures, octagonal column structures, etc.

[0088] In some embodiments, when the application scenario does not require the support leg 130, the support leg 130 is first removed from the connector 131, and when the support leg is needed, the support leg 130 is then installed onto the connector 131 and locked.

[0089] In other embodiments of this application, the support leg 130 and the connector 131 can be replaced with a folding pivot structure, such as... Figure 12 As shown, the support leg 130 is installed and fixed to the rotating shaft connector 1311 through the rotating shaft structure 1302. When it is necessary to rotate the support leg 130, the pin 132 is removed first. At this time, the support leg 130 can rotate relative to the rotating shaft connector 1311. The support leg 130 is fixed at the pin hole 135 position at different angles through the pin 132.

[0090] In some embodiments, the support leg 130 may also be a telescopic structure, such as the support leg 130 having multiple fixing pin holes, and the structural component on the main frame 110 that fixes the support leg 130 adjusting the ground clearance of the support leg 130 by adjusting its cooperation with different fixing pin holes on the support leg 130.

[0091] In some embodiments, such as Figure 10 As shown, the support leg 130 is equipped with a caster wheel 133 at the end away from the main frame 110, which facilitates pushing during manual operation;

[0092] And / or, the connector 131 protrudes from one end of the main frame 110 and is provided with a crash pad 134.

[0093] like Figure 10As shown, the end of the support leg 130 away from the main frame 110 is equipped with a caster wheel 133, which is a 360° rotating wheel used to improve the mobility of the logistics trolley. The use of the caster wheel 133 allows the logistics trolley to turn freely when pushed or dragged, making it easy to move flexibly in narrow spaces or complex paths, and reducing the intensity of manual operation.

[0094] like Figures 10-12 As shown, the connector 131, protruding from the main frame 110, has a crash pad 134, which is a buffer structure used to prevent damage to the trolley from collisions during movement or parking. The crash pad 134 is typically made of rubber, soft plastic, or other cushioning materials, and functions to reduce shock, noise, and protect equipment and the environment. For example, a polyurethane block is installed on the end face of the connector 131 facing away from the vehicle body 100, serving as a crash buffer.

[0095] In some embodiments, such as Figure 10 As shown, a buffer pad 1201 for supporting materials is provided on the shelf 120;

[0096] And / or, the shelf 120 is provided with a plurality of partitions 1202, which are connected by mortise and tenon joints to divide the surface of the shelf 120 into a plurality of receiving areas.

[0097] like Figure 10 As shown, a buffer pad 1201 is provided on the shelf 120 to support materials, and its surface is the direct contact area where the materials are placed. The buffer pad 1201 is usually made of rubber, soft plastic, sponge or other materials with shock absorption properties, and has functions such as anti-slip, shock absorption and anti-scratch.

[0098] Multiple partitions 1202 are provided on the shelf 120, and these partitions 1202 are connected by mortise and tenon joints. Mortise and tenon joints are a traditional and efficient nail-free connection method, which features a stable connection, detachability, and ease of assembly and disassembly. The partitions 1202 divide the surface of the shelf 120 into multiple storage areas through the mortise and tenon joints, which can be used to classify and store different materials, improving space utilization and management efficiency.

[0099] The partition 1202 uses a mortise and tenon structure to flexibly divide the space of the shelf 120, which can be adjusted according to the type and size of materials to achieve refined classification management. The mortise and tenon structure facilitates disassembly and reassembly, making the shelf 120 system highly configurable and adaptable to different operational needs. The partition design makes the storage and retrieval of materials more orderly, reduces search time, and improves operational efficiency.

[0100] In one implementation, the cushioning pad 1201 is made of polyvinyl chloride (PVC) rubber. The partition 1202 is made of polyoxymethylene (POM).

[0101] In the implementation and debugging process of the logistics trolley provided in this application embodiment, the cargo coding module 200 is small in size and is a movable component. It can be directly removed in batches and placed on the workbench to attach cargo codes without tilting the trolley or having personnel crawl under it, which facilitates personnel operation. At the same time, tools such as rulers and laser instruments are used to improve positioning accuracy, which greatly improves implementation efficiency. When the transport vehicle 500 is running, the support leg 130 can be quickly removed by pulling out the pin 135, so that the transport vehicle 500 can detect obstacles without obstruction and avoid blind spots created by the support leg 130, which significantly reduces safety risks. At the same time, due to the guiding and limiting effect of the ring limiting structure 300, the transport vehicle 500 can dock more accurately when docking with the logistics trolley, reducing docking failures caused by ground slope, trolley inconsistency, etc.; it also limits the displacement or movement of the trolley during bumpy driving, preventing cargo code deviation from causing the transport vehicle 500 to stop running, thus improving the operational stability of the transport vehicle 500. The docking of the transport vehicle 500 with the logistics trolley includes mechanical docking and information docking.

[0102] In addition, the logistics trolley provided in this application embodiment can also be compatible with the delivery of non-production materials, such as auxiliary tooling and other tools, by attaching or placing them on the attachment pallet 400, thereby expanding the delivery content of the transport vehicle 500 and reducing logistics operating costs.

[0103] Secondly, such as Figure 5 and Figure 6 As shown, this application embodiment also provides a logistics transportation device, including a transport vehicle 500 and a logistics trolley as described in any of the first aspect embodiments, wherein the transport vehicle 500 is connected to the logistics trolley information via a cargo code.

[0104] The transport vehicle 500 has a scanning unit for scanning cargo codes. When the transport vehicle 500 runs under the floor 121 of the logistics trolley, the scanning unit can scan the cargo code on the cargo code module 200 in the logistics trolley, thereby realizing information docking between the transport vehicle 500 and the logistics trolley.

[0105] The transport vehicle 500 also has a lifting platform. After the transport vehicle 500 moves to the bottom plate 121 of the logistics trolley and completes information docking, the lifting platform can be lifted until it is inserted into the limiting space of the bottom plate 121, thus achieving mechanical docking with the logistics trolley. Finally, the entire logistics trolley is lifted up and automatically navigated to the corresponding position according to the information on the cargo label.

[0106] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
