Description

Technical Field

[0001] The present disclosure relates to the field of logistics technology, and in particular to a transport device and system. Background Art

[0002] Smart logistics terminals often use handling devices, such as handling robots, to automatically transport items, reducing the workload of workers. In related technologies, handling devices often require workers to manually place and retrieve items when transporting them to the handling device or shelves, making the process inconvenient and resulting in low handling efficiency. Utility Model Content

[0003] The present disclosure provides a transport device and a system for automatically placing and picking up items during transport of items by the transport device, thereby improving transport efficiency.

[0004] To achieve the above technical objectives, the present disclosure adopts the following technical solutions:

[0005] In a first aspect, the present disclosure provides a transport device, including a support frame, an unpowered transmission mechanism, a first blocking mechanism and a moving chassis, wherein the unpowered transmission mechanism is arranged in the support frame, and the unpowered transmission mechanism is inclined relative to the bottom surface of the support frame, and the unpowered transmission mechanism forms a storage surface, which is used to carry articles; the first blocking mechanism has a first position and a second position; when the first blocking mechanism is in the first position, the first blocking mechanism is used to prevent articles on the unpowered transmission mechanism from sliding out along the unpowered transmission mechanism; when the first blocking mechanism is in the second position, the articles on the unpowered transmission mechanism slide out along the unpowered transmission mechanism; the moving chassis is connected to the bottom surface of the support frame, and is used to drive the support frame to move.

[0006] The transport device provided by the present disclosure is connected to the bottom surface of the support frame via a moving chassis, and the support frame can be driven to move by the moving chassis. When it is necessary to transport items, the moving chassis can drive the support frame to move to a shelf where items are stored, and dock with the shelf where items are stored, so that the first blocking mechanism is located in a first position. At this time, since the unpowered transmission mechanism is tilted relative to the bottom surface of the support frame, the items on the shelf where items are stored can slide along the unpowered transmission mechanism to the storage surface formed by the support frame under the action of their own weight, and due to the blocking effect of the first blocking mechanism, the items can be placed on the storage surface without falling from the unpowered transmission mechanism.

[0007] The moving chassis then drives the support frame to the shelf where items are to be stored (e.g., a transfer rack) and docks with the shelf, positioning the first blocking mechanism in the second position. At this point, the first blocking mechanism no longer blocks the items within the support frame, allowing the items within the support frame to slide along the unpowered conveyor mechanism under their own weight to the shelf where items are to be stored. This eliminates the need for workers to manually place and retrieve items during the item handling process, making the process more convenient and improving item handling efficiency.

[0008] In addition, by arranging the unpowered transmission mechanism at an angle relative to the bottom surface of the support frame, automatic picking and placing of articles can be achieved, and the structure of the transport device can be made simpler, thereby reducing the cost of the transport device.

[0009] In some embodiments, there are multiple unpowered transmission mechanisms, and surfaces for supporting articles of at least two of the multiple unpowered transmission mechanisms are arranged in parallel.

[0010] By arranging the surfaces for supporting items of at least two of the plurality of unpowered transmission mechanisms in parallel, when placing an item on the support frame, the item can be placed and slid on the at least two unpowered transmission mechanisms with parallel surfaces for supporting items, so that the at least two unpowered transmission mechanisms with parallel surfaces for supporting items can support and transport the same item. In this way, the items are supported over a larger area during stacking within the support frame and during movement between the support frame and the transfer frame, thereby improving the stability of item handling.

[0011] In some embodiments, the unpowered transmission mechanism includes a first end and a second end, and the distance from the first end of the unpowered transmission mechanism to the bottom surface of the support frame is greater than the distance from the second end of the unpowered transmission mechanism to the bottom surface of the support frame; the number of unpowered transmission mechanisms is multiple, and the multiple unpowered transmission mechanisms include a first unpowered transmission mechanism and a second unpowered transmission mechanism; the first ends of the first unpowered transmission mechanism and the second unpowered transmission mechanism are respectively located on opposite sides of the support frame, and the second ends of the first unpowered transmission mechanism and the second unpowered transmission mechanism are also respectively located on opposite sides of the support frame.

[0012] In this way, a first unpowered transmission mechanism and a second unpowered transmission mechanism are set in the support frame, so that the first unpowered transmission mechanism and the second unpowered transmission mechanism are tilted in opposite directions. After the support frame is docked with the external equipment, items can be transmitted to the external equipment through one of the first unpowered transmission mechanism and the second unpowered transmission mechanism, and the other unpowered transmission mechanism receives the items transmitted by the external equipment, so as to realize the storage and retrieval of items at the same time, thereby improving the transportation efficiency.

[0013] In some embodiments, multiple unpowered transmission mechanisms are sequentially spaced apart in a direction perpendicular to the bottom surface of the support frame. This allows for multiple layers of unpowered transmission mechanisms to be arranged perpendicular to the bottom surface of the support frame, facilitating the placement of items in different zones and facilitating the simultaneous transport of different types of items.

[0014] In some embodiments, the transport device also includes a detection device and a controller. The detection device is arranged on the support frame, and the detection range of the detection device at least includes each unpowered transmission mechanism arranged in the support frame; the controller is communicated with the detection device and the first blocking mechanism; the controller is used to obtain the detection result of the detection device, and based on the successful docking of the unpowered transmission mechanism with the external device, control the first blocking mechanism to move from the first position to the second position.

[0015] In this way, the detection result of the detection device can be used to determine whether the unpowered transmission mechanism and the external device are successfully connected. If the connection is successful, the position of the first blocking mechanism is changed to enable the object to be taken and placed. In this way, the object can be automatically taken and placed without user operation, thereby improving the handling efficiency.

[0016] In some embodiments, the transport device also includes a vibration device, which is arranged on the support frame and in contact with the unpowered transmission mechanism; the controller is also communicatively connected to the vibration device; the controller is also used to control the vibration device to vibrate based on the jamming of the article on the unpowered transmission mechanism, so as to drive the article on the unpowered transmission mechanism to vibrate.

[0017] In this way, when an unpowered conveying mechanism is used to transport items, the vibration device can be controlled in time to vibrate the items on the unpowered conveying mechanism when the items get stuck, so as to ensure that the items slide smoothly on the unpowered conveying mechanism, improve the efficiency of taking and placing items, and thus improve the handling efficiency.

[0018] In some embodiments, the transport device also includes a locking structure, which is arranged on the support frame and connected to the first blocking mechanism; the locking structure has a third position and a fourth position; when the locking structure is subjected to external force, the locking structure moves from the third position to the fourth position to move the first blocking mechanism from the first position to the second position; when the external force applied to the locking structure is removed, the locking structure returns to the third position from the fourth position to the third position to move the first blocking mechanism from the second position to the first position.

[0019] In this way, the position of the first blocking mechanism can be controlled by the locking structure, thereby realizing the taking and placing of items; in this way, there is no need to drive the first blocking mechanism to move between the first position and the second position by electric control, thereby simplifying the structure of the transport device and reducing the cost of the transport device.

[0020] In some embodiments, a guide groove is provided on the first blocking mechanism, and when the first blocking mechanism is in the first position, the guide groove extends upwardly from the third position toward the fourth position; the locking structure includes a sliding rod, a collision member and a guide rod, and the sliding rod is slidably connected to the support frame; the collision member is connected to the sliding rod and is located on the outside of the support frame; when the collision member is subjected to external force, the collision member moves from the third position to the fourth position; one end of the guide rod is connected to the sliding rod, and the other end of the guide rod is passed through the guide groove.

[0021] In this way, when the collision member is subjected to external force, the collision member will push the slide rod to slide from the third position to the fourth position, thereby driving the guide rod to slide accordingly, so that the guide rod drives the first blocking mechanism to rotate from the first position to the second position, thereby conveniently adjusting the position of the first blocking mechanism.

[0022] In some embodiments, the locking structure further includes a reset elastic member, which is disposed between the collision member and the support frame and is used to apply an elastic reset force to the collision member to move from the fourth position to the third position.

[0023] In this way, the collision member can be easily moved from the fourth position to the third position by resetting the elastic member, so that the first blocking mechanism can be used again.

[0024] In some embodiments, the support frame includes multiple support columns and multiple support cross bars; the multiple support columns are perpendicular to the bottom surface of the support frame and are arranged around the bottom surface of the support frame; the unpowered transmission mechanism includes a first end and a second end, and the distance from the first end of the unpowered transmission mechanism to the bottom surface of the support frame is greater than the distance from the second end of the unpowered transmission mechanism to the bottom surface of the support frame; the multiple support cross bars include a first support cross bar connected to the first end of the unpowered transmission mechanism, and a second support cross bar connected to the second end of the unpowered transmission mechanism; the first blocking mechanism is connected to the second support cross bar.

[0025] In this way, the first blocking mechanism is located at the second end of the unpowered transmission mechanism. The first blocking mechanism can block the objects on the unpowered transmission mechanism at the second end of the unpowered transmission mechanism, that is, the objects at the lowest end of the unpowered transmission mechanism, thereby blocking all objects on the unpowered transmission mechanism. Therefore, there is no need to set up too many first blocking mechanisms, thereby simplifying the structure of the transport device.

[0026] In some embodiments, the transport device further includes a damper, which is disposed on the unpowered transmission mechanism; the damper is used to reduce the speed at which the article slides along the unpowered transmission mechanism.

[0027] In this way, the damper can reduce the speed at which the object slides along the unpowered transmission mechanism, preventing the sliding of the object from causing collision or damage.

[0028] In some embodiments, the unpowered transmission mechanism includes a bracket and a plurality of rollers, wherein the bracket is connected to the support frame; the plurality of rollers are arranged along the extension direction of the unpowered transmission mechanism and are rotatably connected to the bracket.

[0029] In this way, the friction between the object and the unpowered transmission mechanism can be reduced by the rotation of the roller, so that the object can slide more smoothly on the unpowered transmission mechanism.

[0030] In some embodiments, the transport device further includes a lifting bracket, at least a portion of which is connected between the moving chassis and the support frame; the lifting bracket is used to drive the support frame to raise or lower its height.

[0031] By driving the support frame to rise or fall in height through the lifting bracket, the height of the unpowered transmission mechanism on the support frame can be adjusted, so that the height of the unpowered transmission mechanism can be adjusted according to the height of the unpowered transmission mechanism in the transfer frame to which the unpowered transmission mechanism needs to be docked, so that the unpowered transmission mechanism can be docked with unpowered transmission mechanisms of different heights, thereby improving the applicability of the handling device.

[0032] In some embodiments, the transport device also includes a protective baffle connected to the support frame; the protective baffle is arranged on opposite sides of the track extension direction of the unpowered transmission mechanism, and the protective baffle is arranged to intersect with the surface of the unpowered transmission mechanism used to support items.

[0033] By providing the protective baffle, the articles can be prevented from sliding out from opposite sides of the track extension direction of the unpowered conveying mechanism during the sliding process along the unpowered conveying mechanism, thereby achieving safe transportation of the articles.

[0034] In the second aspect, the present disclosure provides a transport system, which includes a transfer frame and the above-mentioned transport device; wherein, a non-powered conveying mechanism is arranged in the transfer frame, and the non-powered conveying mechanism is arranged at an angle relative to the bottom surface of the transfer frame; one end of the non-powered conveying mechanism in the transport device can be docked with one end of the non-powered conveying mechanism in the transfer frame, and the docked non-powered conveying mechanism and the non-powered conveying mechanism are inclined in the same direction relative to the bottom surface of the transfer frame.

[0035] The transport system provided by the present disclosure can realize the interaction of items between the transport device and the transfer rack (such as the placement and reception of items) by docking the transport device with the transfer rack; it does not require a complex mechanical structure and relies on the gravity of the items themselves to realize the interaction of items, thereby reducing equipment costs and improving transport efficiency.

[0036] In some embodiments, the transfer rack also includes a second blocking mechanism, which has a fifth position and a sixth position; when the second blocking mechanism is in the fifth position, the second blocking mechanism is used to prevent items on the unpowered conveying mechanism in the transfer rack from sliding out along the unpowered conveying mechanism; when the second blocking mechanism is in the sixth position, the items on the unpowered conveying mechanism in the transfer rack slide out along the unpowered conveying mechanism.

[0037] By setting the second blocking mechanism, the second blocking mechanism can be switched between the fifth position and the sixth position, so that the transfer rack can realize the taking and placing of items, and ensure that when items are not taken and placed, the items on the unpowered conveying mechanism will not slide out along the unpowered conveying mechanism, thereby improving the stability of the items on the unpowered conveying mechanism.

[0060] Smart logistics terminals often utilize handling devices, such as handling robots, to automatically transport items, reducing the workload of personnel. Related technologies typically employ complex handling devices for transporting items over long distances. However, this approach results in complex equipment structures and high costs. Furthermore, the efficiency of item retrieval and storage is often low, reducing the efficiency of item handling.

[0061] Based on this, the present disclosure provides a transport system 100. The transport system 100 is used to transport and store items.

[0062] The handling system 100 provided herein is applicable to any scenario requiring item handling, including, but not limited to, automated warehouses, sorting centers, production line handling, cross-regional logistics, cold chain logistics, and the like. Furthermore, the handling system 100 provided herein may be used in fields including, but not limited to, logistics technology, systems engineering, industrial engineering, and storage devices.

[0063] In order to more clearly illustrate the solutions provided by the present disclosure, each embodiment will be described in detail below with reference to the accompanying drawings.

[0064] like Figure 1 As shown, Figure 1 The transport system 100 is a side view of a transport system 100 provided in an embodiment of the present disclosure. The transport system 100 includes a transport device 10 and a transport frame 20. The transport frame 20 is used to store items (such as Figure 1 The transport rack 20 shown in FIG. 1 , i.e., the transport rack 20, can serve as a shelf. The transport device 10 is used to transport items on the transport rack 20. For example, multiple transport racks 20 are placed in an automated warehouse, and multiple types of items are placed on the multiple transport racks 20. If the items need to be reclassified or their storage locations need to be adjusted, the transport device 10 needs to be used to transfer items from one transport rack 20 to another transport rack 20 for storage.

[0065] In order to facilitate the transfer of items by the transport device 10, please continue to refer to Figure 1The transport device 10 includes a support frame 1, an unpowered transmission mechanism 2, and a motion chassis 3. The motion chassis 3 is connected to the bottom surface of the support frame 1 and is used to drive the support frame 1 to move. The unpowered transmission mechanism 2 is disposed within the support frame 1. The support frame 1 is used to fix and support the unpowered transmission mechanism 2. For example, the motion chassis 3 can be a mobile robot with a positioning function.

[0066] It is understandable that the handling device 10 can also be called a handling robot, handling equipment, transfer robot, intelligent distribution equipment, autonomous mobile robots (AMR), etc., and the present disclosure does not make specific limitations on this.

[0067] In some examples, the support frame 1 may include a plurality of support columns 11 and a plurality of support cross bars 12. The plurality of support columns 11 are perpendicular to the bottom surface of the support frame 1 (eg, Figure 1 M shown in the figure), and is arranged around the bottom surface of the support frame 1. Two adjacent support columns 11 are connected by at least one support cross bar 12. A plurality of support columns 11 and a plurality of support cross bars 12 are interconnected to form the support frame 1. In which, when the transport device 10 is in normal use, that is, when the moving chassis 3 drives the support frame 1 to move on the ground, the extension direction of the support column 11 can be in the vertical direction, and the extension direction of the support cross bar 12 can be in the horizontal direction. In some other examples, the support frame 1 can also be other structures that can fix and support the unpowered transmission mechanism 2, which are not specifically limited here.

[0068] When the transport device 10 is transporting an item, the item can be placed on the unpowered transmission mechanism 2 so that the unpowered transmission mechanism 2 supports the item. The moving chassis 3 can drive the support frame 1 to move, and easily drive the unpowered transmission mechanism 2 and the item to move, so as to transport the item.

[0069] For example, when it is necessary to transport items on one of the transfer racks 20 (for the convenience of description, the transfer rack 20 is named the first transfer rack 20) ​​to another transfer rack 20 (for the convenience of description, the transfer rack 20 is named the second transfer rack 20), the movable chassis 3 can drive the support frame 1 to move to the first transfer rack 20, and move the items on the first transfer rack 20 to the unpowered transmission mechanism 2 of the transport device 10. Then, the movable chassis 3 drives the support frame 1 carrying the items to move to the second transfer rack 20, and then moves the items on the unpowered transmission mechanism 2 to the second transfer rack 20 to complete the transportation of the items.

[0070] The unpowered transmission mechanism 2 is tilted relative to the bottom surface of the support frame 1. It should be noted that the bottom surface of the support frame 1 refers to the lower surface of the support frame 1 when the moving chassis 3 drives the support frame 1 to move on the ground.

[0071] In some examples, the unpowered transmission mechanism 2 includes a first end 21 and a second end 22. The distance from the first end 21 of the unpowered transmission mechanism 2 to the bottom surface of the support frame 1 is greater than the distance from the second end 22 of the unpowered transmission mechanism 2 to the bottom surface of the support frame 1. That is, the unpowered transmission mechanism 2 is tilted downward from the first end 21 to the second end 22. The plurality of support cross bars 12 include a first support cross bar 121 and a second support cross bar 122 (see Figure 2 The first support cross bar 121 is connected to the first end 21 of the unpowered transmission mechanism 2 to secure and support the first end 21 of the unpowered transmission mechanism 2. The second support cross bar 122 is connected to the second end 22 of the unpowered transmission mechanism 2 to secure and support the second end 22 of the unpowered transmission mechanism 2. In other words, the second support cross bar 122 is closer to the bottom surface of the support frame 1 than the first support cross bar 121.

[0072] By tilting the unpowered transmission mechanism 2 relative to the bottom surface of the support frame 1, after the items are placed on the unpowered transmission mechanism 2, the items can slide on the unpowered transmission mechanism 2 under the action of their own weight, so that the items can be automatically aligned in the support frame 1, making it easier to arrange and place the items in the support frame 1 and improving the efficiency of carrying the items.

[0073] In order to facilitate the handling device 10 to take and place the items during the transfer process, please continue to refer to Figure 1 The transport frame 20 is provided with an unpowered conveying mechanism 20A. The transport frame 20 is used to support the unpowered conveying mechanism 20A and to support articles placed on the unpowered conveying mechanism 20A.

[0074] It should be noted that the number and structure of the unpowered conveying mechanisms 20A can be the same as the number and structure of the unpowered conveying mechanisms 2 in the transport device 10. The number and structure of the unpowered conveying mechanisms 20A can also be different from the number and structure of the unpowered conveying mechanisms 2 in the transport device 10. This is not specifically limited here.

[0075] This application is illustratively described by taking the example that the number and structure of the unpowered conveying mechanism 20A are the same as the number and structure of the unpowered conveying mechanism 2 in the transport device 10 .

[0076] In some examples, the transport frame 20 can be a frame structure. For example, the transport frame 20 includes a plurality of columns and a plurality of connecting rods. The plurality of columns are perpendicular to the bottom surface of the transport frame 20 and are arranged around the bottom surface of the transport frame 20. At least one connecting rod is provided between any two adjacent columns. The plurality of columns and the plurality of connecting rods are interconnected to form the transport frame 20. In some other examples, the transport frame can also be other structures capable of supporting the unpowered conveying mechanism 20A and the items on the unpowered conveying mechanism 20A, which are not specifically limited here.

[0077] The unpowered conveying mechanism 20A is relative to the bottom surface of the transport frame 20 (such as Figure 1 One end of the unpowered transmission mechanism 2 in the transport device 10 can dock with one end of the unpowered conveying mechanism 20A in the transport frame 20, and the docked unpowered transmission mechanism 2 and the unpowered conveying mechanism 20A are inclined in the same direction relative to the bottom surface of the transport frame 20.

[0078] It should be noted that the transfer rack 20 is usually placed on the ground, and the items stored on the transfer rack 20 are usually placed on the unpowered conveying mechanism 20A. The bottom surface of the transfer rack 20 refers to the lower surface of the transfer rack 20 when the transfer rack 20 normally stores items and is placed on the ground.

[0079] Through the above arrangement, when it is necessary to move the articles on the transfer frame 20 to the handling device 10, for example, when it is necessary to move the articles on the first transfer frame to the handling device 10, it is only necessary to dock the end (i.e., the first end 21) of the unpowered transmission mechanism 2 in the handling device 10 away from the bottom surface of the supporting frame 1 with the end (referred to as the lower end) of the unpowered conveying mechanism 20A in the transfer frame 20 (e.g., the first transfer frame) close to the bottom surface of the transfer frame 20. At this time, the docked unpowered transmission mechanism 2 and the unpowered transmission mechanism 20A are inclined in the same direction relative to the bottom surface of the transfer frame 20. The articles on the unpowered transmission mechanism 20A will slide to the unpowered transmission mechanism 2 of the handling device 10 under the action of their own gravity, and can slide along the unpowered transmission mechanism 2 to automatically align, thereby eliminating the need for staff to manually carry the articles, facilitating the movement of articles from the transfer frame 20 to the handling device 10, and improving the handling efficiency of the articles.

[0080] When it is necessary to move the articles on the transport device 10 to the transfer frame 20, for example, to transfer the articles on the transport device 10 to the second transfer frame 20, it is only necessary to dock the end (i.e., the second end 22) of the unpowered transmission mechanism 2 in the transport device 10 close to the support frame 1 with the end (referred to as the upper end) of the unpowered conveying mechanism 20A in the transfer frame 20 (e.g., the second transfer frame) away from the bottom surface of the transfer frame 20. At this time, the docked unpowered transmission mechanism 2 and the unpowered conveying mechanism 20A are inclined in the same direction relative to the bottom surface of the transfer frame 20. The articles on the unpowered transmission mechanism 2 will slide to the unpowered conveying mechanism 20A of the transfer frame 20 (e.g., the second transfer frame) under the action of their own gravity, and can slide along the unpowered conveying mechanism 20A to automatically align, thereby eliminating the need for staff to manually carry the articles, facilitating the movement of articles from the transport device 10 to the transfer frame 20, and improving the efficiency of article handling.

[0081] In some embodiments, since the unpowered transmission mechanism 2 is tilted relative to the bottom surface of the supporting frame 1, when the transport device 10 is docked with the transfer frame 20, the first end 21 of the unpowered transmission mechanism 2 in the transport device 10 may be docked with the lower end of the unpowered transmission mechanism 20A in the transfer frame 20, or the second end 22 of the unpowered transmission mechanism 2 in the transport device 10 may be docked with the upper end of the unpowered transmission mechanism 20A in the transfer frame 20. In addition, the heights of different transfer frames 20 may also be different, resulting in different heights of the unpowered transmission mechanism 20A in different transfer frames 20 from the bottom surface of the transfer frame 20. Therefore, in order to facilitate the docking of the transport device 10 with the transfer frame 20, and to enable the transport device 10 to meet the requirements of docking with transfer frames 20 of different heights, please continue to refer to Figure 1 The handling device 10 further includes a lifting bracket 4, at least part of which is connected between the moving chassis 3 and the support frame 1. The lifting bracket 4 is used to drive the support frame 1 to rise or fall.

[0082] By driving the support frame 1 to rise or fall in height through the lifting bracket 4, the height of the unpowered transmission mechanism 2 on the support frame 1 can be adjusted, so that the height of the unpowered transmission mechanism 2 can be adjusted according to the height of the unpowered transmission mechanism 20A in the transfer frame 20 to which the unpowered transmission mechanism 2 needs to be docked, so that the unpowered transmission mechanism 2 can be docked with unpowered transmission mechanisms 20A of different heights, thereby improving the applicability of the transport device 10.

[0083] In some examples, the lifting bracket 4 may be a rod-shaped structure, a block-shaped structure, a frame-shaped structure, etc., which are not specifically limited here.

[0084] In some examples, the lifting bracket 4 can be raised and lowered relative to the moving chassis 3. A power element is disposed within the moving chassis 3. The power element is used to drive the lifting bracket 4 to rise and fall relative to the moving chassis 3 to adjust the height of the support frame 1, thereby adjusting the height of the unpowered transmission mechanism 2. The power element can be an electric push rod. Alternatively, the power element can be a motor and a rack and pinion structure.

[0085] In some embodiments, see Figure 2 , Figure 2 This is a schematic diagram of the three-dimensional structure of the transport device 10 provided in an embodiment of the present disclosure. There are multiple unpowered transmission mechanisms 2, and the surfaces of at least two of the multiple unpowered transmission mechanisms 2 for supporting articles are arranged in parallel. In other words, the inclination direction of at least two of the multiple unpowered transmission mechanisms 2 is the same, and along the first arrangement direction (such as Figure 2 The unpowered transmission mechanisms 2 are arranged in a first arrangement direction perpendicular to the extension direction of the unpowered transmission mechanism 2 and parallel to the bottom surface of the support frame 1. At least two unpowered transmission mechanisms 2, each with its surface configured to support an object and arranged parallel to the surface, are configured to support the same object. For example, the object can be a tote, a plate-like object, a rod-like object, or any other object capable of being supported simultaneously by multiple unpowered transmission mechanisms 2, without specific limitation.

[0086] Exemplarily, along a direction perpendicular to the bottom surface of the support frame 1, the support frame 1 is sequentially provided with three layers of unpowered transmission mechanisms 2 from top to bottom, wherein each layer of unpowered transmission mechanisms 2 includes a plurality of unpowered transmission mechanisms 2. Among the plurality of unpowered transmission mechanisms 2 on the same layer, two unpowered transmission mechanisms 2 may have surfaces for supporting articles arranged in parallel. Among the plurality of unpowered transmission mechanisms 2 on the same layer, more than two unpowered transmission mechanisms 2 may have surfaces for supporting articles arranged in parallel. For example, among the plurality of unpowered transmission mechanisms 2 on the same layer, three, four, five, six, etc., unpowered transmission mechanisms 2 may have surfaces for supporting articles arranged in parallel. Figure 2 In the embodiment shown in FIG, the surfaces of the plurality of unpowered conveying mechanisms 2 on each layer for supporting articles are arranged in parallel.

[0087] By having the surfaces for supporting items of at least two of the multiple unpowered transmission mechanisms 2 arranged in parallel, when placing an item on the support frame 1, the item can be placed and slid on the at least two unpowered transmission mechanisms 2 with parallel surfaces for supporting items, so that the at least two unpowered transmission mechanisms 2 with parallel surfaces for supporting items can support and transport the same item. In this way, the items are supported over a larger area during stacking within the support frame 1 and during movement between the support frame 1 and the transfer frame 20, thereby improving the stability of item handling.

[0088] In some examples, the surfaces for supporting items of at least two of the plurality of unpowered conveying mechanisms 2 are located on the same plane. Thus, since the surfaces for supporting items of the at least two unpowered conveying mechanisms 2 are coplanar, i.e., there is no height difference, the items can slide smoothly along the at least two unpowered conveying mechanisms 2 simultaneously, thereby improving the efficiency of item handling.

[0089] In other examples, among the multiple unpowered transmission mechanisms 2, there is a small height difference between the surfaces of at least two of the unpowered transmission mechanisms 2 that are arranged in parallel to support the items. For example, the height difference is greater than or equal to 1 mm and less than or equal to 10 mm. For example, the height difference can be 1 mm, 2 mm, 4 mm, 5 mm, 7 mm, 9 mm, 10 mm, etc.

[0090] In some examples, at least two unpowered conveyor mechanisms 2 are arranged parallel to each other in the first arrangement direction. This reduces the contact area between the unpowered conveyor mechanisms 2 and the objects, reducing the friction experienced by the objects as they slide, thereby increasing the speed and smoothness of the objects sliding on the unpowered conveyor mechanisms 2 and improving handling efficiency, compared to a belt- or plate-shaped unpowered conveyor mechanism.

[0091] In some embodiments, see Figure 3 , Figure 3 for Figure 2 When there are multiple unpowered transmission mechanisms 2, the multiple unpowered transmission mechanisms 2 are sequentially spaced apart in a direction perpendicular to the bottom surface of the support frame 1.

[0092] By sequentially arranging multiple unpowered transmission mechanisms 2 in a direction perpendicular to the bottom surface of the support frame 1, articles can be placed on each unpowered transmission mechanism 2, thereby allowing multiple layers of articles to be placed on the transport device 10. This allows the transport device 10 to carry more articles at a time, thereby improving transport efficiency. Furthermore, different types of articles can be placed on each unpowered transmission mechanism 2, allowing the transport device 10 to carry different types of articles simultaneously, thereby improving transport efficiency and facilitating the classified storage of articles.

[0093] In some examples, each unpowered transmission mechanism 2 may include multiple sub-unpowered transmission mechanisms 2. This can be understood as follows: the multiple unpowered transmission mechanisms 2 are divided into multiple layers along a direction perpendicular to the bottom surface of the support frame 1, and each layer has multiple unpowered transmission mechanisms 2.

[0094] In some embodiments, please refer to Figure 3 There are multiple unpowered transmission mechanisms 2, and the distance from the first end 21 of each unpowered transmission mechanism 2 to the bottom surface of the support frame 1 is greater than the distance from the second end 22 of the unpowered transmission mechanism 2 to the bottom surface of the support frame 1.

[0095] The plurality of unpowered transmission mechanisms 2 include a first unpowered transmission mechanism 23 and a second unpowered transmission mechanism 24. The first ends 21 of the first and second unpowered transmission mechanisms 23 and 24 are respectively located on opposite sides of the support frame 1, and the second ends 22 of the first and second unpowered transmission mechanisms 23 and 24 are also respectively located on opposite sides of the support frame 1. In other words, the support frame 1 has a first side and a second side opposite to each other. Among the plurality of unpowered transmission mechanisms 2, some have their first ends 21 connected to the first side of the support frame 1 and their second ends 22 connected to the second side of the support frame 1; while another portion of the unpowered transmission mechanisms 2 have their first ends 21 connected to the second side of the support frame 1 and their second ends 22 connected to the first side of the support frame 1. In other words, the inclination direction of part of the unpowered transmission mechanism 2 is opposite to the inclination direction of the other part of the unpowered transmission mechanism 2, that is, part of the unpowered transmission mechanism 2 gradually inclines along the direction from the first side to the second side toward the bottom surface of the support frame 1, and the other part of the unpowered transmission mechanism 2 gradually inclines along the direction from the first side to the second side toward the bottom surface of the support frame 1.

[0096] By providing a first unpowered transmission mechanism 23 and a second unpowered transmission mechanism 24 in the support frame 1, so that the first unpowered transmission mechanism 23 and the second unpowered transmission mechanism 24 are inclined in opposite directions, it is possible to enable, after the support frame 1 is docked with the transfer frame 20, one of the first unpowered transmission mechanism 23 and the second unpowered transmission mechanism 24 can transmit items to the transfer frame 20, while the other can receive items transmitted by the transfer frame 20. In this way, the transport device 10 can transport some items to the transfer frame 20 while simultaneously transporting items on the transfer frame 20 to other places, thereby reducing the number of times the transport device 10 moves and improving transport efficiency.

[0097] In some embodiments, please refer to Figure 3 The transport device 10 further includes a first blocking mechanism 5. The first blocking mechanism 5 has a first position and a second position. When the first blocking mechanism 5 is in the first position, the first blocking mechanism 5 is used to prevent the objects on the unpowered conveying mechanism 2 from sliding out along the unpowered conveying mechanism 2; when the first blocking mechanism 5 is in the second position, the objects on the unpowered conveying mechanism 2 are allowed to slide out along the unpowered conveying mechanism 2.

[0098] By setting up the first blocking mechanism 5, when stacking items on the conveying device 10 and the conveying device 10 is conveying items, the first blocking mechanism 5 can be placed in the first position so that the first blocking mechanism 5 blocks the items stacked on the unpowered transmission mechanism 2, thereby preventing the items from sliding off the unpowered transmission mechanism 2 and making the items more stable on the conveying device 10.

[0099] When it is necessary to transfer the items on the transport device 10 to the transfer frame 20, the transport device 10 can be docked with the transfer frame 20, and then the first blocking mechanism 5 can be placed in the second position so that the first blocking mechanism 5 no longer blocks the items on the unpowered transmission mechanism 2. At this time, the items on the unpowered transmission mechanism 2 will slide along the unpowered transmission mechanism 2 to the transfer frame 20 under the action of their own gravity, thereby facilitating the transfer of items.

[0100] For some examples, see Figure 3 and Figure 4 , Figure 4 for Figure 2, which is a front view of the structure of the transport device 10 shown in FIG. The first blocking mechanism 5 is connected to the second support crossbar 122. In other words, the first blocking mechanism 5 is located at the second end 22 of the unpowered transmission mechanism 2. In this way, the first blocking mechanism 5 can block the items on the unpowered transmission mechanism 2 located at the second end 22 of the unpowered transmission mechanism 2, that is, the items at the bottom of the unpowered transmission mechanism 2, thereby blocking all items on the unpowered transmission mechanism 2. Therefore, there is no need to set up too many first blocking mechanisms 5, thereby simplifying the structure of the transport device 10.

[0101] For some examples, see Figure 4 When there are multiple unpowered transmission mechanisms 2, the multiple unpowered transmission mechanisms 2 are spaced apart along the first arrangement direction, and the first blocking mechanism 5 can be located between two adjacent unpowered transmission mechanisms 2. In this way, the first blocking mechanism 5 can be prevented from interfering with the objects on the unpowered transmission mechanism 2 when moving between the first position and the second position, thereby facilitating the installation of the first blocking mechanism 5. Figure 4 In the embodiment, the first blocking mechanism is located at the first position.

[0102] The number of the first blocking mechanisms 5 can be multiple, and the multiple first blocking mechanisms 5 can be spaced apart along the first arrangement direction. In some examples, the support frame 1 is provided with multiple rows of unpowered transmission mechanisms 2 in a direction perpendicular to the bottom surface of the support frame 1, and each row has multiple unpowered transmission mechanisms 2. Then, a first blocking mechanism 5 is provided between the multiple unpowered transmission mechanisms 2 in each row.

[0103] In some examples, the first blocking mechanism 5 can be a plate-shaped structure, a rod-shaped structure, a block-shaped structure, an irregular structure, or the like.

[0104] The first blocking mechanism 5 can move between a first position and a second position in a direction perpendicular to the bottom surface of the support frame 1. The first blocking mechanism 5 can also rotate between the first position and the second position about a first axis, the direction of the first axis being consistent with the first arrangement direction. The first blocking mechanism 5 rotates from the first position to the second position in a direction from the transport device toward the transfer frame to prevent interference between the first blocking mechanism 5 and items on the transport device.

[0105] When the first blocking mechanism 5 is in the first position, at least a portion of the first blocking mechanism 5 is located on the side of the surface of the unpowered transmission mechanism 2 for supporting articles facing away from the bottom surface of the support frame 1, thereby blocking the articles. When the first blocking mechanism 5 is in the second position, the first blocking mechanism 5 is located on the side of the surface of the unpowered transmission mechanism 2 for supporting articles facing the bottom surface of the support frame 1, thereby no longer blocking the articles.

[0106] In some embodiments, please participate Figure 3 and Figure 5 , Figure 5 for Figure 2 The transport device 10 further includes a locking structure 6, which is disposed on the support frame 1 and connected to the first blocking mechanism 5. The locking structure 6 is used to drive the first blocking mechanism 5 to move between the first position and the second position.

[0107] Exemplarily, the locking structure 6 can be a driving member, such as an electric push rod 61. The output shaft of the electric push rod 61 is directly connected to the first blocking mechanism 5. In this case, the first blocking mechanism 5 moves between a first position and a second position in a direction perpendicular to the bottom surface of the support frame 1. In another exemplary embodiment, the driving member can be a motor, the output shaft of which is coaxially arranged with the first axis and connected to the first blocking mechanism 5. In this case, the first blocking mechanism 5 rotates about the first axis between the first position and the second position.

[0108] As another example, the locking structure 6 includes an electric push rod 61 and a connector 62. The first blocking mechanism 5 is rotatably connected to the support frame 1 about a first axis. One end of the connector 62 is connected to the first blocking mechanism 5, and the other end of the connector 62 is rotatably connected to the output shaft of the electric push rod 61. The telescopic movement of the output shaft of the electric push rod 61 can drive the first blocking mechanism 5 to rotate between the first position and the second position through the connector 62. The connector 62 can be a rod-shaped structure, a plate-shaped structure, or the like. The connector 62 can also be an L-shaped structure or a Z-shaped structure.

[0109] In this case, the electric push rod 61 can be arranged on the side of the unpowered transmission mechanism 2 facing the base of the support frame 1, and the axial direction of the output shaft of the electric push rod 61 can be consistent with the extension direction of the unpowered transmission mechanism 2, or it can form a small angle with the extension direction of the unpowered transmission mechanism 2, wherein the angle can be greater than 1° and less than or equal to 20°. For example, the angle can be 1°, 5°, 10°, 15°, 20°, etc. In this way, the space occupied by the electric push rod 61 in the direction perpendicular to the bottom surface of the support frame 1 can be reduced, so that the handling device 10 has more space for placing items, thereby improving the efficiency of item handling.

[0110] When there are multiple first blocking mechanisms 5 on each layer, the multiple first blocking mechanisms 5 can be connected to the same rotating shaft, which is rotatably connected to the support frame 1 around the first axis, and one end of the connecting member 62 is connected to the first rotating shaft. In this way, only one electric push rod 61 is required to drive the multiple first blocking mechanisms 5 to rotate, thereby simplifying the structure of the transport device 10.

[0111] In some other examples, the locking structure 6 includes a connector 62. The transport system includes an electric push rod 61. The electric push rod 61 is connected to the transport frame 20. The first blocking mechanism 5 is rotatably connected to the support frame 1 around a first axis. One end of the connector 62 is connected to the first blocking mechanism 5. When the support frame 1 and the transport frame 20 are docked, the output shaft of the electric push rod 61 can contact the other end of the connector 62, and when the output shaft of the electric push rod 61 is extended, the first blocking mechanism 5 can be driven to move from the first position to the second position through the connector 62. The locking structure 6 also includes a reset member, which is connected between the connector 62 and the support frame 1 and is elastic. During the process of the first blocking mechanism 5 moving from the first position to the second position, the connector 62 can cause the reset member to undergo elastic deformation. In this way, after the output shaft of the electric push rod 61 is retracted, the connector 62 can drive the first blocking mechanism 5 to move from the second position to the first position under the action of the reset member.

[0112] In some other embodiments, the locking structure 6 has a third position and a fourth position. When an external force is applied to the locking structure 6, the locking structure 6 moves from the third position to the fourth position, thereby moving the first blocking mechanism 5 from the first position to the second position. When the external force applied to the locking structure 6 is removed, the locking structure 6 returns from the fourth position to the third position, thereby moving the first blocking mechanism 5 from the second position to the first position.

[0113] Through the above arrangement, when the support frame 1 and the transfer frame 20 are docked, the transfer frame 20 can be brought into contact with the locking structure 6, and pressure can be applied to the locking structure 6, so that the locking structure 6 moves from the third position to the fourth position, and drives the first blocking mechanism 5 to move from the first position to the second position, thereby releasing the first blocking mechanism 5 from blocking the items on the transport device 10. After the transfer of items is completed, the support frame 1 is separated from the transfer frame 20, so that the locking structure 6 is no longer subjected to force, thereby moving the locking structure 6 from the fourth position to the third position, and driving the first blocking mechanism 5 to move from the second position to the first position, so that the transport device 10 can transport items there. In this way, there is no need to drive the first blocking mechanism 5 to move between the first position and the second position by electric control, thereby simplifying the structure of the transport device 10 and reducing the cost of the transport device 10.

[0114] For some examples, see Figure 6 and Figure 7 , Figure 6 for Figure 2 The structural diagram of the transport device 10 shown in FIG. Figure 7 for Figure 6An enlarged schematic diagram of the structure at point B in the figure. The first blocking mechanism 5 is provided with a guide groove 51. When the first blocking mechanism 5 is in the first position, the guide groove 51 extends upwardly and obliquely from the third position toward the fourth position. The first blocking mechanism 5 is capable of rotating about a first axis located between the first end 21 and the second end 22 of the unpowered transmission mechanism 2. The guide groove 51 is located on the side of the first axis that faces the first end 21 of the unpowered transmission mechanism 2.

[0115] The locking structure 6 includes a collision member 63, a slide bar 64 and a guide bar 65. The slide bar 64 is slidably connected to the support frame 1. The slide bar 64 can be located between two adjacent unpowered transmission mechanisms 2 among a plurality of unpowered transmission mechanisms 2 arranged along the first arrangement direction. The sliding direction of the slide bar 64 is parallel to the bottom surface of the support frame 1 and perpendicular to the first arrangement direction. The collision member 63 is connected to the slide bar 64 and is located on the outside of the support frame 1. When the support frame 1 is docked with the transfer frame 20, the collision member 63 can contact the transfer frame 20 and be subjected to pressure from the transfer frame 20. Among them, the collision member 63 can be a plate-like structure, a rod-like structure, a block-like structure, etc.

[0116] One end of the guide rod 65 is connected to the slide rod 64, and the other end of the guide rod 65 is inserted into the guide groove 51. When the first blocking mechanism 5 is in the first position, that is, when the locking structure 6 is in the third position, the other end of the guide rod 65 is located at the end of the guide groove 51 close to the first end 21 of the unpowered transmission mechanism 2, that is, at the lower end of the guide groove 51. Figure 7 In the embodiment, the first blocking mechanism 5 is located at the first position and the locking structure 6 is located at the third position.

[0117] With the above arrangement, when the collision member 63 collides with the transport frame 20, the collision member 63 is forced to push the slide bar 64 away from the transport frame 20, thereby driving the guide bar 65 to slide accordingly. That is, the locking structure 6 moves from the third position to the fourth position.

[0118] The guide rod 65 slides in the guide groove 51 while sliding along with the slide rod 64 , and generates a thrust on the first blocking mechanism 5 , so that the first blocking mechanism 5 rotates downward, thereby rotating the first blocking mechanism 5 from the first position to the second position.

[0119] The locking structure 6 also includes a reset elastic member ( Figure 6 and Figure 7(not shown). The resilient reset member may be a spring, rubber, latex, or other elastic structure. The resilient reset member may be connected between the collision member 63 and the support frame 1, or between the slide bar 64 and the support frame 1. As the locking structure 6 moves from the third position to the fourth position, the resilient reset member is elastically deformed, thereby generating an elastic reset force on the collision member 63 and the slide bar 64 to move from the fourth position to the third position.

[0120] After the support frame 1 is separated from the transfer frame 20, the collision member 63 no longer receives pressure from the transfer frame 20. At this point, the collision member 63 and the slide bar 64 are reset under the action of the reset elastic member. This means that the locking structure 6 moves from the fourth position to the third position, thereby driving the first blocking mechanism 5 to move from the second position to the first position.

[0121] In some embodiments, the transport device 10 further includes a detection device (not shown in the figure). The detection device is arranged on the support frame 1, and the detection range of the detection device at least includes each unpowered transmission mechanism 2 arranged in the support frame 1. Among them, the detection device can be a camera, such as a camera. The detection device can also be a photoelectric detection device, such as an infrared sensor, a laser sensor, a radar rangefinder, etc. In addition, the number of detection devices can be one or more. For example, when the unpowered transmission mechanism 2 has only one layer, the number of detection devices can be one or more. When the unpowered transmission mechanism 2 has multiple layers, the number of detection devices can be multiple, and at least one detection device is set on each layer.

[0122] In one example, when the detection device is a camera device, the shooting range of the detection device includes each unpowered transmission mechanism 2 arranged in the support frame 1, and the detection result of the detection device includes: the image captured by the camera device, and / or, indication information determined based on the image captured by the camera device to indicate whether the unpowered transmission mechanism 2 is successfully docked with the external device.

[0123] In one example, when the detection device is a photoelectric detection device, the detection result of the detection device includes: distance information detected by the photoelectric detection device, and / or indication information determined based on the distance information detected by the photoelectric detection device to indicate whether the unpowered transmission mechanism 2 is successfully docked with the external device.

[0124] The transport device 10 also includes a controller (not shown). The controller can be located on the moving chassis 3 or the support frame 1. The controller is in communication with the detection device and the first blocking mechanism 5. The controller is configured to obtain detection results from the detection device and, based on successful docking of the unpowered transport mechanism 2 with the external device, control the first blocking mechanism 5 to move from the first position to the second position.

[0125] In some examples, the controller is configured with an application program so that the controller controls all or part of the components of the transport device 10 to perform operations based on the application program. For example, the controller can control the movement of all or part of the first blocking mechanism 5 in the transport device 10 based on a preset application program. For another example, the controller can control a detection device to perform detection based on a preset application program.

[0126] With the above arrangement, the detection result of the detection device can be used to determine whether the unpowered transmission mechanism 2 is successfully docked with the external device. If the docking is successful, the first blocking mechanism 5 is controlled to move to the second position to enable the item to be taken or placed. In this way, the item can be automatically taken or placed without user operation, thereby improving the transportation efficiency.

[0127] The detection device can also detect the position information of the transport frame 20. The position information can be determined by GPS positioning or by detecting the distance, which is not specifically limited here.

[0128] The controller can also control the movement route of the moving chassis 3 according to the position information of the transfer frame 20 detected by the detection device, so that the moving chassis 3 drives the supporting frame 1 to move, so that the supporting frame 1 is aligned with the transfer frame 20.

[0129] In some embodiments, please refer to Figure 7 In order to make the items slide more smoothly on the unpowered transmission mechanism 2, the unpowered transmission mechanism 2 includes a bracket 25 and a plurality of rollers 26. The plurality of rollers 26 are arranged along the extension direction of the unpowered transmission mechanism 2 and are rotatably connected to the bracket 25. The direction of the rotation axis of the roller 26 is consistent with the first arrangement direction. In this way, when the items are placed on the unpowered transmission mechanism 2, the items are placed on the plurality of rollers 26, and the rollers 26 are driven to rotate during the sliding process of the items on the unpowered transmission mechanism 2. The rotation of the rollers 26 can reduce the friction between the items and the unpowered transmission mechanism 2, thereby making the items slide more smoothly on the unpowered transmission mechanism 2.

[0130] The roller may be a plastic roller, a metal roller, a metal roller with a bearing, a rubber-coated metal roller with a bearing, or the like.

[0131] In some other embodiments, the unpowered transmission mechanism 2 may also be a chute structure, an unpowered transmission mechanism slider structure, a smooth bar, etc. No specific limitation is given here.

[0132] In some embodiments, to prevent damage to items caused by excessive collision forces between items due to excessive sliding speed on the unpowered conveyor mechanism 2, the transport device 10 further includes a damper (not shown). The damper is disposed on the unpowered conveyor mechanism 2 and is used to reduce the speed at which items slide along the unpowered conveyor mechanism 2. The damper can reduce the speed at which items slide along the unpowered conveyor mechanism 2, preventing collisions or damage caused by excessive sliding.

[0133] In some examples, the damper can be a rotary damper or a friction plate. In other examples, the damper can be a bearing connected to the roller 26. That is, the roller 26 is connected to the bearing, and the bearing is fixed to the bracket 25. The rotation speed of the roller 26 is limited by the rotation speed of the bearing.

[0134] In some examples, a damper is connected to the roller 26 to limit the rotation speed of the roller 26 to reduce the speed at which the object slides along the unpowered conveyor mechanism 2 .

[0135] In some embodiments, please refer to Figure 3 The transport device 10 further includes a vibration device 7. The vibration device 7 is disposed on the support frame 1 and in contact with the unpowered conveying mechanism 2. A controller is also in communication with the vibration device 7. The controller is further configured to control the vibration device 7 to vibrate when an item becomes stuck on the unpowered conveying mechanism 2, thereby causing the item on the unpowered conveying mechanism 2 to vibrate. Whether an item becomes stuck on the unpowered conveying mechanism 2 can be detected by a detection device, such as a camera.

[0136] Through the above-mentioned setting, when using the unpowered conveying mechanism 2 to convey items, the vibration device can be controlled in time to drive the items on the unpowered conveying mechanism 2 to vibrate when the items are stuck, so as to ensure that the items slide smoothly on the unpowered conveying mechanism 2, improve the efficiency of taking and placing items, and thus improve the handling efficiency.

[0137] In some examples, the vibration device 7 may be an electromagnetic vibrator, a piezoelectric crystal vibrator, or the like.

[0138] In some embodiments, the transport device 10 further includes a protective baffle (not shown). The protective baffle is connected to the support frame 1. The protective baffle is disposed on opposite sides of the track extending in the direction of the unpowered conveyor mechanism 2, and the protective baffle is disposed intersecting with the surface of the unpowered conveyor mechanism 2 used to support items. In other words, the support frame 1 is provided with a protective baffle on both sides of the first arrangement direction, and at least a portion of the protective baffle is located on the side of the unpowered conveyor mechanism 2 facing away from the bottom surface of the support frame 1.

[0139] The transport device 10 may make turns or veers while transporting items, which may cause items on the unpowered conveyor mechanism 2 to slide in the first arrangement direction. The protective baffles can block items from sliding in the first arrangement direction, preventing them from falling from opposite sides of the track extending in the unpowered conveyor mechanism 2, thereby ensuring safe transport of the items.

[0140] In some embodiments, a power system (not shown) is provided within the motion chassis 3 to provide power for the movement of the motion chassis 3. The power system includes a drive motor, a battery pack that provides electrical energy to the drive motor, and an electronic control device connected to the drive motor for controlling the drive motor.

[0141] The battery pack can also provide power to electrical components on the support frame 1. For example, the battery pack can power the locking mechanism 6 (e.g., electric push rod 61 or motor) on the support frame 1, enabling the locking mechanism 6 to drive the first blocking mechanism 5. Furthermore, the motion chassis 3 is equipped with a charging connector that can be connected to an outlet or charger to charge the battery pack.

[0142] In some embodiments, the transport frame 20 further includes a second blocking mechanism (not shown). The second blocking mechanism has a fifth position and a sixth position. When the second blocking mechanism is in the fifth position, the second blocking mechanism is used to prevent items on the unpowered conveying mechanism 20A in the transport frame 20 from sliding out along the unpowered conveying mechanism 20A. When the second blocking mechanism is in the sixth position, the items on the unpowered conveying mechanism 20A in the transport frame 20 are allowed to slide out along the unpowered conveying mechanism 20A.

[0143] By setting up a second blocking mechanism, when stacking items on the transfer rack 20, the second blocking mechanism can be placed in the fifth position, so that the second blocking mechanism can block the items stacked on the unpowered conveying mechanism 20A, thereby preventing the items from sliding off the unpowered conveying mechanism 20A, so that the items can be placed more stably on the transfer rack 20.

[0144] When it is necessary to transfer the items on the transfer frame 20 to the transport device 10, the transport device 10 can be docked with the transfer frame 20, and then the second blocking mechanism can be placed in the sixth position so that the second blocking mechanism no longer blocks the items on the unpowered conveying mechanism 20A. At this time, the items on the unpowered conveying mechanism 20A will slide along the unpowered conveying mechanism 20A to the transport device 10 under the action of their own gravity, thereby facilitating the transfer of the items.

[0145] It should be noted that the structure of the second blocking mechanism in the transport frame 20 can be the same as the structure of the first blocking mechanism 5 in the transport device 10. The structure of the second blocking mechanism in the transport frame 20 can also be different from the structure of the first blocking mechanism 5 in the transport device 10. No specific limitation is made here. This application is illustratively described on the basis that the structure of the second blocking mechanism in the transport frame 20 can be the same as the structure of the first blocking mechanism 5 in the transport device 10. The specific structure of the second blocking mechanism will not be further described here.

[0146] In some embodiments, in order to facilitate the switching of the second blocking mechanism between the fifth position and the sixth position, a second locking structure (not shown in the figure) can also be provided on the transfer frame 20 to drive the second blocking mechanism to switch between the fifth position and the sixth position through the second locking structure.

[0147] The structure of the second locking structure can be the same as that of the locking structure 6 in the transport device 10. The structure of the second locking structure can also be different from that of the locking structure 6 in the transport device 10. This is not specifically limited here.
