Description

Technical Field

[0001] This utility model relates to the field of logistics technology, and in particular to an AGV (Automated Guided Vehicle). Background Technology

[0002] With the development of mobile robot technology, AGVs (Automated Guided Vehicles) have been widely used in various industries and are one of the main pieces of equipment for automating material handling in factories and warehouses. In recent years, the huge volume of passenger and cargo transport has put heavy pressure on airport logistics operations, and the traditional airport logistics operation method relying on manual driving faces many challenges. The automated handling method of AGVs can solve the problems of labor shortage and high labor costs in traditional airport logistics to a certain extent, reduce the safety risks of airport baggage logistics operations, and improve the efficiency of airport logistics operations.

[0003] Current AGVs (Automated Guided Vehicles) are open transport platforms. Airports handle a wide variety of luggage, including fragile items and electronic products. These open platforms lack effective protective measures, making luggage susceptible to damage during transport due to collisions caused by the AGVs' vibrations, acceleration, deceleration, or turning. Furthermore, luggage on these open platforms is directly exposed, increasing the risk of theft or loss in the high-traffic environment of airports. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the open transport platform of existing AGVs is prone to causing loss or damage of goods. This invention provides an AGV that avoids exposing goods to the outside, thus improving the safety of goods transportation.

[0005] To solve the above-mentioned technical problems, the present invention discloses an AGV trolley, comprising: a trolley body, including a support platform and a drive system, the drive system being used to drive the trolley body to move on the ground; a housing, disposed on the support platform, the housing including a mounting cavity, the mounting cavity having a storage channel; and a storage component, disposed in the storage channel and slidably connected to the cavity wall of the mounting cavity along the extension direction of the storage channel.

[0006] By adopting the above technical solution, a box is set on the carrier platform of the AGV trolley, and a storage channel is set inside the box. The storage components are connected to the box in a movable manner along the extension direction of the storage channel, so that items can be placed in the storage components, realizing the orderly stacking and storage of items, which significantly increases the loading capacity per unit volume compared to an open platform. On the other hand, the enclosed storage components form an independent storage space, which can effectively resist external environmental interference, avoid damage to goods during transportation due to collisions, vibrations, dust, water stains, etc., and reduce the risk of loss of goods due to exposure, thereby improving the safety of goods transportation.

[0007] According to another specific embodiment of the present invention, it further includes at least one set of partition plates, the set of partition plates including a first partition plate and a second partition plate, the first partition plate and the second partition plate being detachably connected to the cavity wall of the mounting cavity, and the first partition plate and the second partition plate being spaced apart and arranged opposite to each other to define the storage channel in the opposite direction of the first partition plate and the second partition plate, the first partition plate and the second partition plate respectively forming part of two side walls of the storage channel.

[0008] According to another specific embodiment of the present invention, the first partition plate and the second partition plate in the set of partition plates are fixed to the top or bottom wall of the cavity wall of the mounting cavity and extend along the height direction; at least a portion of the storage member is located between the first partition plate and the second partition plate, and both sides of the storage member are slidably connected to the first partition plate and the second partition plate through a slide rail assembly.

[0009] Compared to installing a partition extending from the top wall to the bottom wall within the mounting cavity, this embodiment uses partitions to divide the storage channels. Furthermore, by sliding the partitions, which extend a predetermined distance from the bottom or top wall of the mounting cavity, to the storage components, space is effectively saved, weight is reduced, and the integrity of the mounting cavity is maintained. On the other hand, the partitions are detachably connected to the mounting cavity, allowing for flexible adjustment of the number of storage channels based on the size and shape of the stored goods. For example, if the original channels are narrow and suitable for storing small items, when larger items need to be stored, some partitions can be removed, the layout rearranged, and the width of the storage channels expanded, reducing the number of channels. This fully utilizes the space within the mounting cavity and improves storage efficiency.

[0010] According to another specific embodiment of the present invention, the slide rail assembly includes: an outer fixed rail extending along the extension direction of the storage channel, the outer fixed rail being fixed to the first partition plate and the second partition plate respectively; an intermediate rail nested inside the outer fixed rail; a first ball bearing groove defined between the side of the intermediate rail facing the outer fixed rail and the outer fixed rail along the height direction; an inner fixed rail fixed to both sides of the storage component and nested inside the intermediate rail; a second ball bearing groove defined between the side of the intermediate rail facing the inner fixed rail and the inner fixed rail along the height direction; a first ball bearing group confined in the first ball bearing groove to allow the intermediate rail to slide relative to the outer fixed rail along the extension direction of the storage channel; and a second ball bearing group confined in the second ball bearing groove to allow the inner fixed rail to slide relative to the intermediate rail along the extension direction of the storage channel.

[0011] Using the above technical solution, the intermediate rail slides in segments as the storage component slides outwards from the storage channel: In the initial stage, the storage component is pulled out 0-55% of its stroke, such as 1%, 25%, 35%, 55%, etc., and the inner fixed rail slides relative to the intermediate rail via the second set of steel balls. The intermediate rail does not move temporarily (because static friction is greater than rolling friction). In the subsequent stage, the storage component is pulled out 55%-100% of its stroke, such as 55%, 75%, 95%, etc., the inner fixed rail drives the intermediate rail, the first set of steel balls begins to roll, and the intermediate rail slides relative to the outer fixed rail. This continues until the storage component slides out of the mounting cavity to its maximum extent. This slide rail assembly, including an outer fixed rail, an intermediate rail, and an inner fixed rail, has a strong load-bearing capacity, can achieve full extension, and has a long service life.

[0012] According to another specific embodiment of the present invention, the AGV trolley includes multiple storage components, and multiple sets of partition plates are fixed in the mounting cavity. The multiple sets of partition plates define multiple independent storage channels. The multiple storage channels correspond one-to-one with the multiple storage components and are slidably connected. Each storage channel has a first opening at one end of its extension direction. The first opening allows the corresponding storage component to slide out or slide into the storage channel along the extension direction of the storage channel.

[0013] According to another specific embodiment of the present invention, the plurality of storage channels are spaced apart in a first direction of the housing and all extend along a second direction; and / or the plurality of storage channels are spaced apart in a second direction of the housing and all extend along a first direction; the first direction is perpendicular to the second direction.

[0014] According to another specific embodiment of the present invention, the plurality of partition plates include: a first set of partition plates, wherein the first partition plate and the second partition plate of the first set of partition plates both extend along a second direction and are both fixed to the bottom wall of the mounting cavity; the first partition plate and the second partition plate of the first set of partition plates are spaced apart and opposite to each other in a first direction of the housing to define a first storage channel in the first direction of the housing; and a second set of partition plates, wherein the second set of partition plates is located above the first set of partition plates in the height direction and is spaced apart from the first set of partition plates; the first partition plate and the second partition plate of the second set of partition plates both extend along a second direction and are both fixed to the top wall of the mounting cavity. The first and second partitions of the second set of partitions are spaced apart and opposite to each other in a first direction of the housing to define a second storage channel in the first direction of the housing; the third set of partitions is located on one side of the first set of partitions in a first direction; the first and second partitions of the third set of partitions both extend along a second direction and are both fixed to the bottom wall of the mounting cavity, and the first and second partitions of the third set of partitions are spaced apart from the top wall of the mounting cavity in the height direction; the first and second partitions of the third set of partitions are spaced apart and opposite to each other in the first direction of the housing to define a third storage channel in the first direction of the housing.

[0015] Using the above technical solution, the three storage units corresponding to the three storage channels can be used to store different types of items. For example, one storage unit can be used for documents and files, another for small tools such as security scanners, and a third for food. Thus, in airport baggage transport, baggage from different flights and of different sizes can be categorized and stored in different storage units, carrying more cargo within a limited space, effectively improving transport efficiency and reducing empty runs. Furthermore, different types of items can be stored in separate storage units and clearly labeled, making it easier for staff to quickly find the items they need. For example, passenger baggage can be categorized according to different flights and destinations and placed in different storage units, making management and scheduling during transport more convenient and reducing the possibility of errors and confusion.

[0016] According to another specific embodiment of the present invention, the box body is provided with a second opening, the second opening and the first opening are respectively located at both ends of the box body in a second direction; the projected area of ​​the second opening in the second direction is greater than the projected area of ​​each of the plurality of storage components in the second direction; a cover plate is provided at the second opening, the cover plate is detachably connected to the box body to close the second opening.

[0017] By adopting the above technical solution, the cover plate is detachably connected to the box body, and the projected area of ​​the second opening in the second direction is larger than the projected area of ​​each of the multiple storage components in the second direction, thereby making it convenient for operators to open the cover plate to check the condition inside the installation cavity or to carry out maintenance and other work.

[0018] According to another specific embodiment of the present invention, each storage component includes a front end and a rear end, the front end facing out of the mounting cavity through the first opening, and the rear end located inside the mounting cavity; a fixing seat is provided inside the mounting cavity, the fixing seat being spaced apart from the rear end of the storage component, and a lock is provided on the fixing seat, the lock being used to connect with the rear end of the storage component to fix the storage component, or to drive the storage component to move along the extension direction of the storage channel and toward the outside of the storage channel.

[0019] According to another specific embodiment of the present invention, it further includes a controller and a button. The controller is located inside the mounting cavity, and the button is located on the outer surface of the housing where the first opening is provided. The controller is electrically connected to the lock and the button. The button can be pressed to switch the lock from a locked state to an unlocked state.

[0020] Using the above technical solution, when the user presses the button on the outer surface of the cabinet, a signal is transmitted to the controller inside the mounting cavity. Upon receiving the signal, the controller sends an unlocking command to the lock. Upon receiving the command, the lock releases its lock on the rear end of the storage component and pushes the storage component along the extension direction of the storage channel and toward the outside of the storage channel, causing the storage component to pop out of the mounting cavity of the cabinet, making it convenient for staff to retrieve the items stored inside.

[0021] In this way, users can automatically pop out the storage compartment simply by pressing a button, without having to manually pull it open. This is especially suitable for scenarios where heavy items are stored or where manual operation is inconvenient, greatly improving ease of use, preventing items from falling or being lost, and increasing operational efficiency. Furthermore, the lock reliably secures the storage compartment, preventing it from accidentally opening due to vibration or bumps during transportation or handling, thus protecting the items inside.

[0022] According to another specific embodiment of the present invention, at least a portion of the outer edge of the bottom of the trolley body is covered with a safety contact edge.

[0023] By adopting the above technical solution, the safety contact edge on the vehicle body forms an all-round safety protection barrier. Whether moving forward, backward or turning, if there is a slight contact with an obstacle (such as a wall, equipment, pedestrian, etc.), the vehicle body can quickly stop or change its direction of travel, effectively avoiding collision accidents and ensuring the safety of personnel and the integrity of goods.

[0024] According to another specific embodiment of the present invention, a laser anti-collision sensor is also included, which is disposed on the support platform and located outside the mounting cavity.

[0025] By adopting the above technical solution, the laser anti-collision sensor can issue an early warning when the AGV body approaches an obstacle based on accurate distance detection, thereby achieving active obstacle avoidance, avoiding collision accidents, and ensuring the safety of the AGV and its cargo.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] refer to Figure 1 This application provides an AGV trolley 100, including a trolley body 200, a box 300, and a storage unit 400.

[0048] Among them, such as Figure 2 As shown, Figure 2 The diagram shows a perspective view of the AGV 100 with its housing 300 hidden. The AGV body 200 includes a platform 210 and a drive system 220, which propels the AGV body 200 to move on the ground. Exemplarily, the AGV body 200 of the AGV 100 is a differential wheel AGV, which has a simple structure and low cost. It achieves steering through the differential motion of its two wheels, allowing for flexible maneuvering and adaptation to complex path requirements. It is understood that the AGV body 200 can also be driven by other types of drives, such as single-wheel drive or multi-wheel drive.

[0049] For example, at least part of the outer edge of the bottom of the vehicle body 200 is covered with a safety contact edge 230, thereby forming an all-round safety protection barrier. Whether moving forward, backward or turning, if there is a slight contact with an obstacle (such as a wall, equipment, pedestrian, etc.), the vehicle body 200 can quickly stop running or change its running direction, effectively avoiding collision accidents and ensuring the safety of personnel and the integrity of goods.

[0050] For example, the vehicle body 200 is rectangular. However, those skilled in the art will understand that in other embodiments, the vehicle body 200 may also be other shapes, such as circular, polygonal, etc.

[0051] Furthermore, a laser anti-collision sensor 240 is also provided on the support platform 210. For example, the support platform 210 is also roughly rectangular in shape, and the laser anti-collision sensor 240 is located at two corners of the support platform 210. Based on accurate distance detection, it can issue an early warning when the AGV body 200 approaches an obstacle, realize active obstacle avoidance, thereby avoiding collision accidents and ensuring the safety of the AGV 100 and the goods it carries.

[0052] like Figures 1 to 3 As shown, the aforementioned housing 300 is mounted on the support platform 210. The housing 300 includes a mounting cavity 301, within which a storage channel 302 is provided. In this embodiment, the housing 300 is hollow to form the mounting cavity 301, and the storage channel 302 is part of the mounting cavity 301. The aforementioned laser anti-collision sensor 240 is located outside the mounting cavity 301.

[0053] For example, the housing 300 is generally rectangular in shape and is fixed to the support platform 210 by screws. That is, the movement of the trolley body 200 causes the housing 300 located on its support platform 210 to move synchronously. It is understood that this application does not limit the shape of the housing 300 and the support platform 210. In other embodiments, the housing 300 and the support platform 210 may also be circular, polygonal, etc.

[0054] The aforementioned storage device 400 is disposed in the storage channel 302, and along the extending direction of the storage channel 302 (e.g., Figure 2 It is slidably connected to the cavity wall of the mounting cavity 301 in the Y direction shown. For example, the storage unit 400 is used to store items.

[0055] Using the above technical solution, a box 300 is set on the carrier platform 210 of the AGV trolley 100 body 200. A storage channel 302 is set inside the box 300. The storage component 400 is connected to the box 300 in a movable manner along the extension direction of the storage channel 302, so that items can be placed in the storage component 400, realizing the orderly stacking and storage of goods, which significantly increases the loading capacity per unit volume compared with an open platform. On the other hand, the enclosed storage component 400 forms an independent storage space, which can effectively resist external environmental interference, avoid damage to goods during transportation due to collisions, vibrations, dust, water stains, etc., and reduce the risk of goods being easily lost due to exposure.

[0056] like Figures 1 to 3 As shown, in this embodiment, the mounting cavity 301 includes three independent storage channels 302: a first storage channel 310, a second storage channel 320, and a third storage channel 330. Correspondingly, three storage components 400 are provided: a first storage component 410 in the first storage channel 310, a second storage component 420 in the second storage channel 320, and a third storage component 430 in the third storage channel 330. The first storage channel 310 and the second storage channel 320 are spaced apart in the height direction Z of the housing 300, and the third storage channel 330 is located on one side of the first storage channel 310 and the second storage channel 320 in the first direction X.

[0057] refer to Figure 2 and Figure 4 In this embodiment, the above-mentioned multiple storage channels 302 are all rectangular in shape, and each storage channel 302 extends along the second direction Y of the housing 300. The length direction of the storage channel 302 corresponds to the second direction Y of the housing 300, and the width direction of the storage channel 302 corresponds to the first direction X of the housing 300. That is, the extension direction of the storage channel 302 is the second direction Y of the housing 300.

[0058] For example, the width of each storage channel 302 is defined by the spacing between the first and second partitions in a set of partitions. Specifically, the width of the first storage channel 310 is defined by the spacing between the first partition 304a and the second partition 304b in the first set of partitions 304, the width of the second storage channel 320 is defined by the spacing between the first partition 305a and the second partition 305b in the second set of partitions 305, and the width of the third storage channel 330 is defined by the spacing between the first partition 306a and the second partition 306b in the third set of partitions 306.

[0059] Specifically, such as Figures 2 to 5 As shown, the first storage channel 310 is located on the bottom wall 301a of the mounting cavity 301 and extends upward to a predetermined distance. The first partition plate 304a and the second partition plate 304b of the first set of partition plates 304 both extend along the second direction Y and can be detachably connected to the bottom wall 301a of the mounting cavity 301. The first partition plate 304a and the second partition plate 304b of the first set of partition plates 304 are spaced apart and opposite to each other in the first direction X of the housing 300 to define the first storage channel 310 in the first direction X of the housing 300. Thus, the first partition plate 304a and the second partition plate 304b respectively form part of the two side walls of the first storage channel 310, and the two sides of the first storage member 410 located in the first storage channel 310 in the first direction X are respectively opposite to the first partition plate 304a and the second partition plate 304b. The first storage unit 410 is slidably connected to the first partition plate 304a and the second partition plate 304b via a slide rail assembly 810, so that the first storage unit 410 can slide relative to the housing 300 in the second direction Y. The specific structure of the slide rail assembly 810 is described later.

[0060] In this embodiment, both the first partition plate 304a and the second partition plate 304b of the first set of partition plates 304 are L-shaped, each including a horizontal portion 308a and a vertical portion 309a. The horizontal portion 308a is parallel to the bottom wall 301a of the mounting cavity 301 and is fixed to the bottom wall 301a of the mounting cavity 301. The vertical portion 309a extends upward along the height direction Z to approximately one-third of the height of the first storage member 410, so as to achieve a sliding connection with the first storage member 410 through the slide rail assembly 810. It is understood that the first partition plate 304a and the second partition plate 304b can also be other shapes, such as T-shaped. The vertical portion 309a can also extend upward along the height direction Z to other distances close to the height of the first storage member 410, such as one-half.

[0061] Furthermore, such as Figure 3 As shown, one end of the first storage channel 310 in the extending direction (i.e., the second direction Y) is provided with a first opening 311, so that the first storage element 410 can slide out and slide into the first storage channel 310 along the second direction Y. Similarly, refer to Figure 2 , Figure 4 and Figure 6 As shown, the second storage channel 320 is disposed on the top wall 301b of the mounting cavity 301 and extends downward along the height direction Z to a set distance. The first partition plate 305a and the second partition plate 305 of the second set of partition plates 305 both extend along the second direction Y and can be detachably connected to the top wall 301b of the mounting cavity 301. The first partition plate 305a and the second partition plate 305 of the second set of partition plates 305 are spaced apart and opposite to each other in the first direction X of the housing 300 to define the second storage channel 320 in the first direction X of the housing 300. The first partition plate 305a and the second partition plate 305b respectively form part of the two side walls of the second storage channel 320, and the two sides of the second storage member 420 located in the second storage channel 320 in the first direction X are respectively opposite to the first partition plate 305a and the second partition plate 305b. The second storage unit 420 is slidably connected to the first partition plate 305a and the second partition plate 305b via a slide rail assembly 820, thereby enabling the second storage unit 420 to slide relative to the housing 300 along the second direction Y. The specific structure of the slide rail assembly 820 is described later.

[0062] In this embodiment, the first partition 305a and the second partition 305b of the second set of partitions 305 are also L-shaped, each including a horizontal portion 308b and a vertical portion 309b. The horizontal portion 308b is parallel to the top wall 301b of the mounting cavity 301 and is fixed to the top wall 301b of the mounting cavity 301. The vertical portion 309b extends downward along the height direction Z to approximately seven-eighths of the height of the second storage member 420, so as to achieve a sliding connection with the second storage member 420 through the slide rail assembly 820. It is understood that the first partition 305a and the second partition 305b can also be other shapes, such as T-shaped. The vertical portion 309b can also extend downward along the height direction Z to other distances close to the height of the second storage member 420, such as four-fifths of the height.

[0063] Furthermore, such as Figure 3 As shown, one end of the second storage channel 320 in the extension direction (i.e., the second direction Y) is provided with a first opening 321 so that the second storage element 420 can slide out and slide into the second storage channel 320 along the second direction Y. The first opening 321 of the second storage channel 320 has the same cross-sectional area as the first opening 311 of the first storage channel 310, and is spaced apart in the height direction Z.

[0064] refer to Figure 2 , Figure 4 and Figure 7 Similar to the first storage channel 310, the third storage channel 330 is located on the bottom wall 301a of the mounting cavity 301 and extends upward to be flush with the top of the second storage channel 320. The first partition plate 306a and the second partition plate 306b of the third set of partition plates 306 both extend along the second direction Y and are both fixed to the bottom wall 301a of the mounting cavity 301. The first partition plate 306a and the second partition plate 306b of the third set of partition plates 306 are spaced apart and opposite to each other in the first direction X of the housing 300 to define the third storage channel 330 in the first direction X of the housing 300. The first partition plate 306a and the second partition plate 306b respectively form part of the two side walls of the third storage channel 330, and the two sides of the third storage member 430 located in the third storage channel 330 in the first direction X are respectively opposite to the first partition plate 306a and the second partition plate 306b. The third storage unit 430 is slidably connected to the first partition plate 306a and the second partition plate 306b via a slide rail assembly 830, thereby enabling the third storage unit 430 to slide relative to the housing 300 along the second direction Y. The specific structure of the slide rail assembly 830 is described later.

[0065] In this embodiment, the first partition 306a and the second partition 306b of the third set of partitions 306 are both L-shaped, each including a horizontal portion 308c and a vertical portion 309c. The horizontal portion 308c is parallel to the bottom wall 301a of the mounting cavity 301 and is fixed to the bottom wall 301a of the mounting cavity 301. The vertical portion 309c extends upward along the height direction Z to one-sixth of the height of the third storage member 430, so as to achieve a sliding connection with the third storage member 430 through the slide rail assembly 830. It is understood that the first partition 306a and the second partition 306b can also be other shapes, such as T-shaped. The vertical portion 309c can also extend upward along the height direction Z to other distances close to the height of the third storage member 430, such as one-fifth of the height.

[0066] Furthermore, such as Figure 3 As shown, one end of the third storage channel 330 in the extending direction (i.e., the second direction Y) is provided with a first opening 331, so that the third storage component 430 can slide out and slide into the third storage channel 330 along the second direction Y. That is, the three storage channels 302 mentioned above correspond one-to-one with the three storage components 400 and are slidably connected; one end of the extending direction of each storage channel 302 is provided with a first opening (i.e., the aforementioned first openings 311, 321, 331), so that the corresponding storage component 400 can slide out or slide into the storage channel 302 along the extending direction of the storage channel 302. It can be understood that the storage component 400 in this embodiment is a drawer-type structure.

[0067] Therefore, compared to setting an entire partition extending from the top wall 301b to the bottom wall 301a within the mounting cavity 301, this embodiment divides multiple storage channels 302 using multiple sets of partitions. Furthermore, by slidingly connecting the partitions, which extend a predetermined distance from the bottom wall 301a or top wall 301b of the mounting cavity 301, to the storage component 400, space is effectively saved, weight is reduced, and the integrity of the mounting cavity 301 is maintained. On the other hand, since all sets of partitions are detachably connected to the mounting cavity 301, the number of storage channels 302 can be flexibly adjusted according to the size, shape, and other characteristics of the stored goods. For example, if the original storage channels 302 are narrow and suitable for storing small items, when larger items need to be stored, some partitions can be removed, the layout rearranged, the width of the storage channels 302 expanded, and the number of storage channels 302 reduced, thereby fully utilizing the space within the mounting cavity 301 and improving storage efficiency.

[0068] In this embodiment, the three storage units 400 can be used to store different types of items. For example, the first storage unit 410 is used for documents and data, the second storage unit 420 is used for small tools, such as security scanners, and the third storage unit 430 is used for food. Furthermore, for example, in airport baggage transportation, baggage from different flights and of different sizes can be categorized and stored in the respective storage units 400, carrying more cargo within a limited space, effectively improving transportation efficiency and reducing empty runs. On the other hand, different types of items can be stored separately in different storage units 400 and clearly labeled, making it easier for staff to quickly find the required items. For example, passengers' checked baggage can be categorized according to different flights, destinations, etc., and placed in different storage units 400, making management and scheduling more convenient during transportation and reducing the possibility of errors and confusion.

[0069] In this embodiment, the three storage devices 400 and their corresponding storage channels 302 are all rectangular. The first storage channel 310 and the second storage channel 320 have the same cross-sectional area, while the third storage channel 330 has a cross-sectional area greater than the sum of the cross-sectional areas of the first and second storage channels 310. However, those skilled in the art will understand that in other embodiments, the storage channels 302 can also be of other shapes, such as polygons, and the cross-sectional area of ​​each storage channel 302 can be set according to requirements; for example, the three storage channels 302 can have the same cross-sectional area.

[0070] Furthermore, the number, location, and configuration of storage channels 302 can be set according to actual needs, such as 1, 2, or 4 channels.

[0071] Taking the configuration of four rectangular storage channels 302 as an example, it can be as follows: Figure 8 The four storage channels 302 shown have the same cross-sectional area and are arranged in pairs, with two channels per column and two channels per row. Alternatively, they could be arranged as follows: Figure 9 The four storage channels 302 shown have the same cross-sectional area and are spaced apart in the first direction X of the housing 300. Alternatively, as... Figure 10 Of the four storage channels 302 shown, two storage channels 302a have the same cross-sectional area, and the other two storage channels 302b have the same cross-sectional area. The two storage channels 302a are spaced apart in the first direction X of the housing 300, and the other two storage channels 302b are located on one side of the two storage channels 302a in the first direction X, and the two storage channels 302b are spaced apart in the height direction Z of the housing 300.

[0072] Furthermore, the first openings of the plurality of storage channels 302 (i.e., the aforementioned first openings 311, 321, 331) can be as shown in this embodiment. Figure 3As shown, multiple storage channels 302 are provided on an outer surface 300a of the housing 300 in the second direction Y, and all extend along the second direction Y, so that the storage element 400 can slide out or slide into the storage channel 302 in the second direction Y. Alternatively, the first openings of the multiple storage channels 302 (i.e., the aforementioned first openings 311, 321, 331) can be provided on an outer surface 300b of the housing 300 in the first direction X, and all extend along the first direction X, so that the storage element 400 can slide out or slide into the storage channel 302 in the first direction X. Alternatively, the first opening of some of the multiple storage channels 302 may be located on an outer surface 300a of the housing 300 in the second direction Y, and these multiple storage channels 302 extend along the second direction Y. The first opening of the other multiple storage channels 302 may be located on an outer surface 300b of the housing 300 in the first direction X, and these multiple storage channels 302 extend along the first direction X. The storage channels 302 extending along the first direction X and the storage channels 302 extending along the second direction Y do not interfere with each other.

[0073] refer to Figures 4 to 7 Since the above-mentioned slide rail assemblies (i.e. slide rail assemblies 810, 820, 830) have the same structure, this embodiment will only take the slide rail assembly 810 slidingly connecting the first partition plate 304a and the first storage component 410 in the first group of partition plates 304 as an example for explanation.

[0074] Specifically, such as Figure 4 and Figure 5 As shown, the slide rail assembly 810 includes an outer fixed rail 811, an intermediate rail 812, and an inner fixed rail 813. The outer fixed rail 811 extends along the extension direction of the first storage channel 310 (that is, the second direction Y of the housing 300) and is fixed to the first partition plate 304a.

[0075] The intermediate rail 812 is nested inside the outer fixed rail 811. Exemplarily, the outer fixed rail 811 is U-shaped, with its opening facing the first storage member 410 along the first direction X. The intermediate rail 812 is nested inside the outer fixed rail 811 through this opening. Along the height direction Z, a first ball bearing groove 814 is defined between the side of the intermediate rail 812 facing the outer fixed rail 811 and the outer fixed rail 811. The first ball bearing groove 814 accommodates a first retainer 815, on which a first ball bearing assembly 816 is provided, allowing the intermediate rail 812 to slide relative to the outer fixed rail 811 along the extending direction of the first storage channel 310.

[0076] The inner fixing rail 813 is fixed to one side of the first storage member 410 in the first direction X and is nested inside the intermediate rail 812. Exemplarily, the intermediate rail 812 includes an opening facing the first storage member 410, through which the inner fixing rail 813 is nested inside the intermediate rail 812.

[0077] Along the height direction Z, the side of the intermediate rail 812 facing the inner fixed rail 813 and the inner fixed rail 813 define a second ball rolling groove 817; the second ball rolling groove 817 accommodates a second retainer 818, and the second retainer 818 is provided with a second ball group 819, so that the inner fixed rail 813 slides relative to the intermediate rail 812 along the extension direction of the first storage channel 310.

[0078] In this process, the intermediate rail 812 slides in segments as the first storage component 410 slides outward toward the first storage channel 310: Initially, the first storage component 410 extends 0-55% of its travel, for example, 1%, 25%, 35%, 55%, etc. The inner fixed rail 813 slides relative to the intermediate rail 812 via the second steel ball assembly 819, and the intermediate rail 812 remains stationary (because static friction is greater than rolling friction). In subsequent segments, the first storage component 410 extends 55%-100% of its travel, for example, 55%, 75%, 95%, etc. The inner fixed rail 813 drives the intermediate rail 812, the first steel ball assembly 816 begins to roll, and the intermediate rail 812 slides relative to the outer fixed rail 811. This continues until the first storage component 410 slides outward toward the mounting cavity 301 to its maximum extent.

[0079] The slide rail assembly 810 of this embodiment, which includes an outer fixed rail 811, a middle rail 812, and an inner fixed rail 813, has strong load-bearing capacity, can be fully extended, and has a long service life.

[0080] In this embodiment, a sliding connection between the storage component 400 and the partition plate is achieved through a slide rail assembly 810 comprising an outer fixed rail 811, an intermediate rail 812, and an inner fixed rail 813. However, those skilled in the art will understand that in other embodiments, the sliding connection between the storage component 400 and the partition plate can also be achieved in other ways, such as a bottom-supporting slide rail, a two-section roller slide rail, etc.

[0081] In this embodiment, reference Figure 11 and Figure 12 The housing 300 is provided with a second opening 303, which, along with the first openings (i.e., the aforementioned first openings 311, 321, and 331), is located at both ends of the housing 300 in the second direction Y. The projected area of ​​the second opening 303 in the second direction Y is larger than the projected area of ​​each of the plurality of storage components 400 in the second direction Y. A cover plate 307 is provided at the second opening 303, which is detachably connected to the housing 300 to close the second opening 303. For example, the detachable connection of the cover plate 307 to the housing 300, and the larger projected area of ​​the second opening 303 in the second direction Y than the projected area of ​​each of the plurality of storage components 400 in the second direction Y, facilitates the operator to open the cover plate 307 to inspect the interior of the mounting cavity 301 or perform maintenance.

[0082] like Figure 13 As shown, each storage unit 400 in this embodiment is provided with a lock 600 to lock the storage unit 400, ensuring that the storage unit 400 will not be accidentally opened due to vibration, bumps or other factors, and protecting the safety of the items inside the storage unit 400.

[0083] refer to Figure 2 , Figure 13 , Figure 14 and Figure 15 ,in Figure 14 A perspective view showing the connection between the third storage unit 430 and its corresponding lock 600 is shown. Figure 15 A partial perspective view of the lock 600 in its locked state is shown. Figure 13 As shown, each of the above-mentioned storage components 400 includes a front end 401 and a rear end 402. The front end 401 faces outward from the mounting cavity 301 through a corresponding first opening (e.g., the first opening 431 of the third storage component 430), and the rear end 402 is located inside the mounting cavity 301. A fixing seat 500 is provided inside the mounting cavity 301, and the fixing seat 500 is spaced apart from the rear end 402 of the storage component 400. A lock 600 is provided on the fixing seat 500, and the lock 600 includes an unlocked state and a locked state. In the locked state (e.g., ... Figure 14 and Figure 15 As shown, the lock 600 is connected to the storage unit 400; in the unlocked state, the lock 600 is disengaged from the storage unit 400.

[0084] For example, the lock 600 is an electronic lock. The mounting base 500 is fixed to the bottom wall 301a of the mounting cavity 301 by screws. It should be noted that... Figure 13 This is a 3D view of the AGV 100 with the housing 300 hidden, and does not mean that the mounting base 500 is directly fixed to the support platform 210. Understandably, the mounting base 500 can also be fixed to the bottom wall 301a of the mounting cavity 301 in other ways, such as snap-fitting or welding.

[0085] like Figures 13 to 15 As shown, the lock 600 includes a latch 601 and a pop-out mechanism (not shown). The rear end 402 of the storage member 400 is provided with a locking ring 440. In the locked state, the latch 601 is connected to the locking ring 440 to fix the storage member 400. Exemplarily, the locking ring 440 is U-shaped, and the latch 601 includes a connected groove 602 and a blocking portion 603. The groove 602 is also generally U-shaped. When the latch 601 moves in one direction (e.g., ...), the latch 601... Figure 15Rotate the device (in the direction R1) by a set angle, and its blocking part 603 extends into the space enclosed by the locking ring 440. The locking ring 440 is simultaneously located in the slot 602. The blocking part 603 restricts the locking ring 440 from disengaging from the slot 602. That is, the locking tongue 601 hooks the locking ring 440 in the extension direction of the storage channel 302, restricting the storage member 400 from sliding along the extension direction of the storage channel 302 and toward the outside of the mounting cavity 301.

[0086] Correspondingly, the locking tongue 601 moves in the other direction (e.g.) Figure 15 The bolt 601 rotates by a set angle (as shown in the R2 direction) to disengage from the locking ring 440, and drives the ejection mechanism to slide the storage member 400 along the extension direction of the storage channel 302 toward the outside of the mounting cavity 301. For example, the bolt 601 rotates in another direction (such as...) Figure 15 Rotating the latch 601 (in the R2 direction) by a set angle causes the blocking part 603 to disengage from the space enclosed by the locking ring 440, and the locking ring 440 also disengages from the slot 602. The rotation of the latch 601 causes the ejection mechanism connected to it to extend in the second direction Y, contact the rear end 402 of the storage unit 400, and push the storage unit 400 to slide out along the second direction (that is, the extension direction of the storage channel 302), thereby facilitating the user to retrieve the items in the storage unit 400.

[0087] Furthermore, a controller (not shown in the figure) is also provided inside the mounting cavity 301, and a button 700 is provided on the outer surface 300a of the housing 300, which has a first opening (e.g., the first opening 431 of the third storage component 430). Figure 1 As shown, the controller is electrically connected to the lock 600 and the button 700. The button 700 can be pressed to switch the lock 600 from the locked state to the unlocked state.

[0088] When the user presses button 700 on the outer surface 300a of the housing 300, a signal is transmitted to the controller inside the mounting cavity 301. Upon receiving the signal, the controller sends an unlocking command to the lock 600. Upon receiving the command, the lock 600 drives the bolt 601 in another direction (e.g., ...). Figure 15 The lock tongue 601 rotates at a set angle (as shown in the R2 direction) to disengage from the locking ring 440. At the same time, the rotation of the locking tongue 601 drives the pop-out mechanism connected to it to extend in the second direction Y, contact the rear end 402 of the storage unit 400, and push the storage unit 400 to slide out along the second direction Y (that is, the extension direction of the storage channel 302), so that the user can easily retrieve the items in the storage unit 400.

[0089] When it is necessary to close the storage device 400, the user manually pushes the storage device 400 into the storage channel 302, with the rear end 402 of the storage device 400 approaching the lock 600. The controller then controls the locking tongue 601 to move in one direction (e.g., ...). Figure 15Rotate the lock tongue 601 (in the direction shown R1) by a set angle, and hook the lock ring 440 in the extension direction of the storage channel 302, restricting the storage component 400 from sliding along the extension direction of the storage channel 302 and towards the outside of the mounting cavity 301, thus locking the storage component 400.

[0090] In this way, users only need to press button 700 to automatically pop out storage component 400 without having to manually pull it open. This is especially suitable for storing heavy items or for scenarios where the installation location is inconvenient for manual operation, greatly improving the ease of use. In addition, the automatic locking function when closing prevents items from falling or being lost due to the storage component 400 not being locked properly, thus improving operational efficiency.

[0091] In addition, the lock 600 reliably secures the storage unit 400, preventing it from being accidentally opened due to vibration, bumps, or other factors during transportation or handling, thus protecting the safety of the items inside the storage unit 400.
