Abstract
Description
Technical Field
[0001] The present disclosure relates to a carrier, and more particularly to a carrier including a plurality of storage devices, such as a carrier for use as a delivery carrier. Background Art
[0002] In traditional brick-and-mortar commerce, goods are typically distributed sequentially from the manufacturer to the wholesaler, then to the retailer, and finally to the customer. The retail store serves as the end point of the distribution chain. Customers are often responsible for the "last mile" of goods delivery—that is, transporting the goods from the physical point of purchase to the customer's home. The end point of the distribution chain may extend all the way to the consumer's home.
[0003] However, e-commerce largely doesn't place the customer in charge of the "last mile" of delivery. Instead, products purchased online are promptly transported from distribution centers to customer-accessible pickup points or delivered directly to the customer's home. Consequently, the growth of online shopping has spawned a variety of different e-commerce models for online purchases. These include order-and-collect models, in which customers who purchase or select goods online can pick them up at a selected store or centralized pickup location, or home delivery services, where goods are delivered directly to the customer's residence.
[0004] The Order and Collect model is a secure access system for delivering goods ordered online to automated pickup locations accessible to customers. The automated pickup locations typically take the form of groups of electronically operated lockers that can be controlled by a locker management system to control the allocation and access to one or more of a plurality of lockers upon receipt of a goods order. Upon receipt of a goods order, access to the lockers can be provided by sending a pickup code to the customer's device. Such a code, when uniquely associated with the order, is entered into a local user interface coupled to the group of electronically operated lockers, access to the goods stored in the one or more lockers assigned to the customer is granted.
[0005] Home delivery services can be provided using a driver-operated vehicle. After receiving a customer's order, the order is packaged at a warehouse or distribution center and loaded onto a vehicle. The vehicle then drives to the customer's home or other pickup address, where the driver delivers the order to the customer's door. Home delivery services can be provided by the retailer or supplier of the goods, or alternatively, by a third party.
[0006] When a vehicle driver retrieves goods from a vehicle to deliver to a customer's door, it's beneficial to present the goods at the appropriate height and angle, considering that drivers may spend a significant amount of time during their workday repeatedly retrieving and delivering goods to different customers. A vehicle with the goods presented in the appropriate manner saves time, speeding up delivery while also being more comfortable and safer for the driver.
[0007] Another option is automated delivery. After receiving a customer order, it's packaged at a warehouse or distribution center and loaded onto an automated vehicle. The vehicle has one or more compartments to store the customer's orders. The vehicle then drives to the customer's residence or other delivery address, where the customer can retrieve their order from the vehicle.
[0008] In the case of autonomous deliveries, since there's no driver to retrieve the goods from the vehicle and deliver them to the customer's door, customers are required to retrieve their own goods from the vehicle. This can be difficult, especially for large orders, such as grocery orders. Shopping bags can be heavy and difficult to lift from the vehicle. Since the customers are members of the general public, order retrieval must be accessible to everyone, including people of varying heights and abilities, including the elderly or those with disabilities.
[0009] In addition, the carrier must ensure that customers can only access their own orders and cannot access other orders within the same carrier.
[0010] Therefore, it would be advantageous to provide a device that enables a user to quickly and easily remove cargo from a carrier. Summary of the Invention
[0011] A vehicle is disclosed, comprising: a first row of one or more first type storage devices, each first type storage device including a first carrier configured to be moved outwardly from a first storage position to a first deployed position substantially outside a footprint of the carrier; a second row of one or more second-class storage devices, the second row of one or more second-class storage devices positioned vertically above the first row of first-class storage devices, wherein each of the one or more second-class storage devices includes a second carrier configured to be moved outwardly from the second storage position to a second deployed position substantially outside a footprint of the carrier; The spatial volume occupied by one of the second carriers in the second deployed position is at least a portion of the spatial volume occupied by one of the first carriers in the first deployed position.
[0012] The advantage of this arrangement is that it allows for both high-density storage of goods in the carrier and easy retrieval of the goods. By overlapping the spatial volumes of the first carrier and the second carrier, the first carrier and the second carrier can be presented at a suitable height for easy retrieval of their goods. This is particularly important for bulk orders (such as grocery orders) that include multiple bags or heavy bags or heavy items. If the goods are presented at too low a height, lifting the bags or heavy items may be difficult. Similarly, if the goods are presented at too high a height, retrieval of the goods may also be difficult because the goods need to be lifted up from the carrier and then lowered. Visibility of the goods may be insufficient, and good visibility is required for picking up the goods or lifting the handles of the bags containing the goods.
[0013] Presenting cargo in a carrier in a deployed position outside the footprint of the carrier is advantageous because the cargo can be presented at a height and / or angle that is different from the height and / or angle of the carrier in the stowed position. The deployed position can be selected to be at a suitable height and / or angle for accessing the cargo while not affecting the packaging of the cargo in the carrier.
[0014] In some embodiments, the carrier may include more rows of storage devices, such as a third row of storage devices. Depending on the size of the carrier, any number of rows of storage devices may be provided. Any number of storage devices may be provided in each row.
[0015] The one or more first carriers may be configured to move from the first storage position to the first deployed position by sliding and tilting in a substantially horizontal direction such that the first carriers are rotated relative to a horizontal plane in the first deployed position.
[0016] Horizontal sliding will cause the first carrier to move from a first storage position within the carrier coverage area to outside the carrier coverage area, where the carrier can be accessed. The first carrier in the deployed position can be tilted upwards (e.g. away from the customer or user) or tilted downwards (e.g. towards the customer or user). Tilting downwards can present the goods in the first carrier at a suitable angle, making it easier to remove the goods. In addition, the advantage of the first carrier being tilted downwards is that it is easier to see the contents of the first carrier, so that the goods can be removed and checked that the correct goods are presented. In the case of accessing the first carrier from the front, tilting upwards can be advantageous, that is, the first carrier is tilted upwards so that the bottom of the first carrier (which is horizontal in the storage position) is tilted upwards (e.g. away from the customer or user), and the front is tilted backwards (e.g. away from the user or customer), making it easier to access the goods or items in the carrier.
[0017] The first carrier may further comprise a slide which is configured to be supported by two or more bearings when the moving member moves in a substantially horizontal direction along the substantially horizontal portion of the guide. The advantage of the slide (separate from the guide) is that the slide can bear most of the weight of the first carrier. Therefore, the guide does not need to be strong enough to bear the full weight of the first carrier and any cargo contained therein, and therefore the guide can be manufactured using lighter and cheaper materials. The slide can be a simple straight flange at the bottom of the first carrier. Using two or more bearings can ensure that the first carrier remains level when moving in a substantially horizontal direction guided by the substantially horizontal portion of the guide.
[0018] The outer shell can restrict the first carrier's rotation relative to the outer shell when the first carrier is in the first storage position, and can allow the first carrier to rotate relative to the outer shell when the first carrier is in the first deployed position. The advantage of the outer shell restricting the first carrier's rotation is that when the first carrier moves from the first storage position to the first deployed position, the first carrier cannot "break out" of the first position, thereby preventing the first carrier from completely detaching from the carrier. Having the outer shell perform the function of restricting the first carrier's rotation eliminates the need for a separate component or mechanism (such as a stop) to perform this function, thereby advantageously reducing the number of components, cost, and complexity of the first-type storage device.
[0019] The first carrier may include a front face that is movable to provide access to the interior of the first carrier for ease of loading and unloading. This feature is particularly advantageous where the goods or items are packed into storage containers (e.g., standard-sized storage containers used in warehouses or storage and retrieval systems) because the storage containers can be loaded and unloaded directly into and from the first carrier in the carrier without having to repack the goods or items into the first carrier.
[0020] The first type of storage device may further include a chain connected to the first carrier at a first end such that pulling the chain at a second end causes the first carrier to move from the first deployed position to the first stored position. This allows the first carrier to be retracted from the first deployed position to the first stored position without having to manually return the first carrier to the first stored position. Manually returning the first carrier to the first stored position not only requires a certain amount of physical strength but is also inconvenient when holding goods or shopping bags.
[0021] The chain can be constrained by a chain guide so that the chain is sufficiently rigid that pushing the chain at the second end moves the first carrier from the first storage position to the first deployed position. The chain guide allows the chain to be both pushed and pulled so that the same chain can be used to move the first carrier from the deployed position to the storage position and from the storage position to the deployed position. It is advantageous not to have to manually pull the first carrier out to the first deployed position. Not only does manually pulling the first carrier out to the first deployed position require physical effort, but manually pulling the first carrier out can also make it difficult to identify which first-class storage device is the first-class storage device that holds the requested order.
[0022] The guide member may include a chain guide. This is particularly advantageous in embodiments where the first type storage device includes an arrangement of guide members and moving members as described above, because the chain can be guided by the guide member without requiring a separate chain guide for the first type storage device, thereby advantageously reducing the number of components, weight, and complexity of the first type storage mechanism.
[0023] At least one of the second carriers can be configured to move from a second stowed position to a second deployed position, wherein the second deployed position is at a lower vertical level than the deployed position. Advantageously, this arrangement allows for more efficient use of space within the carrier, as cargo and items can be transported at a high vertical level, thereby utilizing all available space within the carrier, while still allowing the second carrier to be presented at a suitable height for retrieval of the cargo / items from the second carrier.
[0024] The second carrier may be further configured to tilt so that the second carrier rotates relative to a horizontal plane in the second deployed position. The second carrier in the second deployed position may be tilted upward (e.g. away from the customer or user) or tilted downward (e.g. towards the customer or user). As described above, tilting the second carrier downward enables the goods in the second carrier to be presented at a suitable angle, making it easier to remove the goods. Additionally, the advantage of tilting the second carrier downward is that it is easier to see the contents of the second carrier so that the goods can be removed and to check that the correct goods are presented. In the case where the second carrier is accessed from the front, tilting upward may be advantageous, i.e. the second carrier is tilted upward so that the bottom of the second carrier (which is horizontal when in the second storage position) is tilted upward (e.g. away from the customer or user) and the front is tilted backward (e.g. away from the user or customer), enabling easier access to the goods or items in the second carrier.
[0025] The second category of storage devices may include: a first link pivotally connected at a first end to a first fixed point on the carrier and pivotally connected at a second end to the second carrier; a second link pivotally connected at a first end to a second fixed point on the carrier and pivotally connected at a second end to the second carrier; The second carrier is configured to follow a curved path from the second storage position to the second deployed position.
[0026] The second link may be shaped such that the first link and the second link can pivot below a horizontal plane without the first link interfering with the second link to lower the second carrier to the second deployed position.
[0027] The shape of the first link can be designed so that: when the second carrier is in the second deployed position, the second link rests on the first link at two contact points between the first link and the second link. Advantageously, the two contact points make the configuration of the first link and the second link more stable when in the second deployed position.
[0028] The first fixed point can be at a vertical level lower than the second fixed point so that the first link cannot interfere with the second link, allowing the first and second links to lower the second carrier to the second deployed position. Vertically offsetting the first and second fixed points is an alternative way to allow the first and second links to rotate below the horizontal plane, and does not require the first or second links to be bent or angled, that is, the first and second links can both be straight elongated members, but still be able to rotate below the horizontal plane. Advantageously, straight elongated members are easier to manufacture and less expensive than curved, angled or other shaped links. Typically, the length, shape and position of the first and second links can be varied to define the path that the second carrier takes between the second storage position and the second deployed position.
[0029] The vehicle can be autonomous. The advantage of autonomous vehicles is that they can save labor costs by eliminating the need for a human driver, while still enabling door-to-door delivery. Autonomous vehicles may include one or more sensors (e.g., cameras, radar, lidar, sonar, global positioning systems (GPS), etc.) and a control system configured to receive input from the one or more sensors to enable the vehicle to travel between destinations with minimal or no input from a human driver. The control system may be configured to control one or more of the vehicle's speed, steering, and braking. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 A carrier 1 is schematically illustrated with two rows of storage devices. A first row 11 (shown as the lower row) includes first-type storage devices 12, each of which includes a first carrier 100. The first carriers 100 are in a first storage position 13, or closed position, in which the first carriers 100 of the first-type storage devices are substantially within the carrier 1. When the first carriers of the first-type storage devices are in the first storage position, any cargo or items within the first carriers 100 are inaccessible from outside the carrier.
[0053] A second row 21 (shown as the upper row) includes second type storage devices 22. Second row 21 is located vertically above first row 11. Each second type storage device 22 includes a second carrier 200 in a second storage position 23 (i.e., a closed position), in which the second carrier of the second type storage device is substantially within carrier 1. When the second carrier 200 of the second type storage device 22 is in the second storage position, any cargo or items within the second carrier 200 are inaccessible from outside the carrier.
[0054] In the illustrated embodiment, there are four first type storage devices 12 in first row 11 and four second type storage devices 22 in second row 21, with second row 22 positioned directly above first row 11 such that each second type storage device 22 is positioned directly above a respective first type storage device 12. In other embodiments, as described below, different numbers or arrangements of first type storage devices 12 and second type storage devices 22 are possible.
[0055] Figure 1 The illustrated carrier 1 includes a pair of carrier doors 40 on opposite sides of the carrier 1. The carrier doors 40 on the proximal side of the carrier 1 are in an open position to facilitate deployment of the first type of storage devices 12 and the second type of storage devices 21 as described below. The carrier doors 40 on the distal side of the carrier 1 are in a closed position to prevent access to the storage devices 12, 22 on the distal side of the carrier 1. The carrier doors 40 in this embodiment are upwardly and outwardly opening flap-type doors, which advantageously do not impede the movement of storage devices and do not extend beyond the footprint of the carrier 1, which is advantageous in confined spaces. In other embodiments, different types or configurations of carrier doors 40 may be used.
[0056] Figure 2 Schematically shows Figure 1 carrier 1, wherein a first type storage device of the first type storage device (in Figure 2 The first carrier 100, designated 12a), is in a first deployed position 14, or open position. In the first deployed position 14, the first carrier 100 of the first type of storage device 12a is substantially outside the footprint of the carrier 1, and any cargo or items within the first type of storage device are accessible from outside the carrier. When in the first deployed position 14, the first carrier 100 of the first type of storage device 12a occupies a spatial volume 15. For clarity, the spatial volume 15 is shown in FIG. Figure 2The first type of storage device 12b is placed in a storage position 13 on a first carrier. In the illustrated embodiment, the first type of storage device 12 is a tilting drawer mechanism with a first carrier 100 that slides out horizontally and tilts downward, thereby presenting the contents of the first carrier 100 at a convenient angle for easy retrieval. In other embodiments, the first type of storage device 12 may be a different type of storage device.
[0057] Figure 3 Schematically shows Figure 1 1 , wherein the second carrier 200 of one of the second type storage devices 22 is in a second deployed position 24, i.e., an open position. In the second deployed position 24, the second carrier 200 of the second type storage device 22a is substantially outside the footprint of the carrier 1, and any cargo or items within the second carrier of the second type storage device are accessible from outside the carrier. When in the second deployed position 25, the second carrier 200 of the second type storage device 22 occupies a spatial volume 25. For clarity, the spatial volume 25 is illustrated on the second carrier of another second type storage device 22b in the second storage position 23. In the illustrated embodiment, the second type storage device 22 is a pull-down box mechanism, in which the carrier 200 extends outward, downward, and tilts downward, thereby presenting the cargo at a suitable angle and height for easy retrieval. In other embodiments, the second type storage device 22 may be a different type of storage device.
[0058] Although Figure 2 and Figure 3 The first type of storage device 12 and the second type of storage device 22 are shown as different types of storage devices, but in other embodiments, the first type of storage device 12 and the second type of storage device 22 can be the same type of storage devices.
[0059] from Figure 2 and Figure 3As can be seen, the spatial volume 15 occupied by the first carrier of the first type storage device 12 in the first deployed position 14 overlaps with the spatial volume 25 occupied by the second carrier of the second type storage device 22 in the second deployed position 24. This is done to allow orders to be retrieved from the storage device at a suitable height for lifting the bag out of the carrier. If there were no overlap between the spatial volumes 15 and 25, the second carrier 200 of the second type storage device 22 in the second deployed position 23 would be too high, making it difficult to remove the goods, especially if the order includes a heavy bag full of groceries. The lower height of the second deployed position 23 also allows visibility of the second carrier 200 of the second type storage device 22, meaning that the contents of the second carrier 200 can be easily viewed. The ability to see the contents of the first and second carriers 100, 200 facilitates verification of the correctness of the presented order and allows the order to be easily removed, for example by grabbing the item or lifting the grocery bag by its handle.
[0060] In some embodiments, one or more of the first carrier of the first type of storage device and / or the second carrier of the second type of storage device may include a storage container. Figure 2 Storage containers are shown within a first carrier 100 of a first type of storage device 12a. Using storage containers can be more convenient when loading a carrier with orders for delivery, particularly when loading or unloading the carrier at a warehouse or fulfillment center (where standard storage containers are used as part of the storage, retrieval, and picking process). Orders packed into storage containers at the warehouse can then be quickly and easily loaded into or unloaded from a carrier of a carrier's storage device without the need for unpacking and repacking.
[0061] from Figure 2 As can be seen in the diagram, the first carrier 100 of the first type storage device 12a is sized to accommodate exactly one storage container. In some embodiments, each first carrier of each first type storage device 12 and each second carrier 200 of each second type storage device 22 accommodates a storage container. In other embodiments, some of the first carriers 100 and second carriers 200 can accommodate storage containers, while other portions of the first carriers 100 and second carriers 200 can directly hold items, and / or some of the first carriers 100 and second carriers 200 can accommodate more than one storage container.
[0062] Despite Figures 1 to 3In the illustrated embodiment, the first and second carriers 100, 200, and the storage containers therein, are oriented with their long sides parallel to the sides of the carrier 1. However, in other embodiments, the first and second carriers 100, 200, and the storage containers therein, can be presented in a different orientation, i.e., with their short sides parallel to the sides of the carrier 1. This latter arrangement may be advantageous when the long sides of the first and second carriers 100, 200, and the storage containers therein, on opposite sides of the carrier, extend across the width of the carrier. The carriers and storage containers occupy more space within the carrier, thereby achieving a higher storage density and more efficient use of the space within the carrier.
[0063] In some embodiments, multiple storage containers may be used in the same first carrier or second carrier. In other embodiments, the cargo or items may be placed directly in the first carrier and the second carrier without the use of storage containers.
[0064] In a grid-based storage and retrieval system, storage containers can be used to store items. The advantage of using storage containers in carriers 1 is that storage containers containing orders from the grid-based storage and retrieval system can be placed directly into the carriers, and the orders can be removed from the carriers without having to manually move or empty items from storage containers or pack or unpack items. This improves system efficiency, resulting in faster order fulfillment and lower costs. Inclined drawer mechanism - first embodiment
[0065] exist Figure 2 In the illustrated embodiment, the first type of storage device 12 is a tilt-type drawer mechanism, in which the carrier 100 is configured to slide outward in a substantially horizontal direction relative to the carrier 1 and then tilt. The tilt-type drawer mechanism 12 includes the carrier 100 continuously sliding between a first storage position 13 (in which the carrier 100 is completely within the carrier) and a first deployed position 14 (in which the carrier 100 is substantially outside the carrier's footprint and tilted downward). In other embodiments, the carrier 100 can be tilted upward.
[0066] Figure 4 (a-c) illustrate a possible embodiment of the tilted pull-out box mechanism 12. Although described herein as a "tilted pull-out box mechanism," this mechanism is not limited to the case where the carrier 100 is a pull-out box. In the illustrated embodiment, the carrier 100 takes the form of an open box, a cube with a bottom, four side walls, and an open top. In other embodiments, the carrier 200 may take a different form, such as a tray or shelf, or a box with a removable lid.
[0067] The movement of the carrier 100 is constrained by the guide member 101. The carrier 100 includes a moving member (not shown) configured to slide along the guide member 101 to guide the movement of the carrier 100. In the illustrated embodiment, a pair of guide members 101 are arranged on opposite sides of the carrier 100. The guide members 101 are supported by a column 102, which supports two guide members 101 on opposite sides of the column 102 to guide two adjacent carriers 100. The guide member 101 has a substantially horizontal portion 103 that guides the carrier 100 outward in a substantially horizontal direction, and an upturned portion 104 that guides the carrier 100 downward.
[0068] The weight of the carrier 100 is supported by runners 106 attached to the bottom of the side of the carrier 100. The runners 106 are supported by bearings 107 at the bottom of the columns 102. As the moving member of the carrier 100 moves along the horizontal portion 103 of the guide 101, the runners 106 rest on the bearings 107. As the moving member of the carrier 100 moves along the upturned portion 104 of the guide 101, the carrier 100 tilts downward and the runner 106 pivots on one of the bearings 107.
[0069] exist Figure 4 In (a), the carrier 100 is in the storage position. Figure 4 In (b), the carrier 100 is in an intermediate position between the stowed position and the deployed position. The moving member is still in the horizontal portion 103 of the guide 101 and the carrier 100 is substantially horizontal. The slide 106 is supported by more than one bearing 107 on the column 102. Figure 4 In (c) the carrier 100 is in the deployed position. The moving member is at the top of the upturned portion 104 of the guide 101. The carrier 100 has tilted forward and downward and the runner 106 at the bottom of the carrier 100 is pivoted on one of the bearings 107.
[0070] Depending on the specific shape of the upturned portion 104 of the guide 101, the movement of the carrier 100 when it moves between the intermediate position and the deployed position can be a pure pivotal movement on one of the bearings 107, or a combination of a pivotal movement around the bearing 107 and a sliding movement of the slide 106 along the bearing 107.
[0071] Figure 5 (ac) are in (a) storage position, (b) intermediate position, and (c) deployed position Figure 4 A side view of the tilting drawer box mechanism 12 in FIG. The moving member 105 is indicated by a dotted circle. The moving member 105 is fastened to the side of the carrier 100 and slides within the guide 101 to move the carrier 100 relative to the guide 101. Figure 5In (a), the carrier 100 is in the storage position and the moving member 105 is behind the horizontal portion 103 of the guide 101. Figure 5 In (b), the carrier 100 is in the middle position and the moving member 105 is towards the front of the horizontal portion 103 of the guide 101. Figure 5 In (c), the carrier 100 is in the deployed position, and the moving member 105 is at the front / top of the upturned portion 104 of the guide 101 .
[0072] In order to stop the carrier 100 in the deployed position and prevent it from tilting further, the carrier 100 is provided with a protrusion 115 and the guide 101 is provided with a stop 116. When in the deployed position, the protrusion 115 on the carrier 100 abuts against the stop 116 of the guide 101. Figure 5 As can be seen in (c), the protrusion 115 is in contact with the stopper 116 .
[0073] In some embodiments, the movement of the tilt-down drawer mechanism 12 may be automated. Figure 5 (a-c) illustrate an embodiment of a tilting drawer mechanism 12 that can be used to deploy and retract a carrier 100. A moving member 105 on the side of the carrier 100 is connected to the distal end of a chain 110. The chain 110 passes through the guide 101, around a sprocket 108 at the rear end of the guide 101, and into a container 109. The sprocket 108 is rotated by a motor 117. To move the carrier 100 from the storage position to the deployed position, the sprocket 108 rotates and pushes the chain 110 along the guide 101. The distal end of the chain 110 then pushes the moving member 105 along the guide 101, moving the carrier 100 forward. To retract the carrier 100 from the deployed position to the storage position, the sprocket 108 rotates in the opposite direction and pulls the chain 110 back along the guide 101. The chain 110 then pulls the moving member 105 along the guide 101, moving the carrier 100 backward. The guide 101 constrains the chain 110 so that the chain 110 remains rigid enough to be pushed and pulled. Without the guide 101, when the chain 110 is pushed by the rotation of the sprocket 108, the chain 110 will be deformed and unable to transmit force to the far end of the chain 110 and push the moving member 105 along the guide 101.
[0074] exist Figure 5In (ac), the moving member 105 (i.e., the connection point of the chain 110 to the carrier 100) is shown in a position toward the top and toward the rear of the side of the carrier 100. In other embodiments, the moving member 105 can be connected to the carrier 100 at different locations on the carrier 100. The shape and position of the guide 101 and the position of the moving member 105 on the carrier 100 can be varied to define the path that the carrier 100 takes between the stored position and the deployed position.
[0075] Figure 6 The principle of using a chain 110 to push the carrier 100 to the deployed position is shown. When the chain 110 is unconstrained, applying a force to one end causes the chain 110 to deform rather than transmit the force. However, when the chain 110 is constrained by a guide 101, applying a force to one end of the chain causes the force to be transmitted to the other end of the chain. The guide 101 limits the lateral movement of the chain, so that the pushing force can be transmitted. In this way, the guide 101 allows the chain 110 to be used for both pushing (i.e., for pushing the carrier 100 from the storage position to the deployed position) and pulling (i.e., for retracting the carrier 100 from the deployed position to the storage position). In other embodiments, different mechanisms may be used to automate the movement of the tilt-type drawer mechanism 12. For example, a drive belt or rope may be used as an alternative to the chain in the illustrated embodiment.
[0076] Figure 7 The tilting drawer mechanism 12 shown has a guide member 101 that includes a substantially horizontal portion 103, an upturned portion 104, and a downturned portion 111. In the illustrated embodiment, the downturned portion 111 of the guide member 101 allows the carrier 100 to slide further out and further down while remaining at approximately the same angle relative to the horizontal plane as when the moving member 107 passes over the upturned portion 104. In other embodiments, the downturned portion 111 of the guide member 101 can be shaped so as to cause the carrier 101 to tilt further forward.
[0077] exist Figure 7 , the moving member 105 (i.e., the point of connection of the chain 110 to the carrier 100) is shown as being located on an arm 118 extending from the body of the carrier 100. In other embodiments, the moving member 105 may be connected to the carrier 100 at different locations on the carrier 100. The shape and position of the guide 101 and the position of the moving member 105 on the carrier 110 may be varied to define the path that the carrier 100 takes between the stowed position and the deployed position. Figure 7 In the embodiment of FIG. 1 , the moving member 105 is located at the distal end of the arm 118 , which enables the carrier 100 to be moved further out and tilted further downward.
[0078] In some embodiments, the first type storage device and the second type storage device on the carrier can both be tilt-type pull-out box mechanisms 12. The second type storage device in the second row can be Figure 7 The illustrated embodiment shows a tilted pull-out box mechanism 12 with a guide 101, wherein the guide 101 includes a substantially horizontal portion 103, an upturned portion 104, and a downturned portion 111. The first row of first-type storage devices may be tilted pull-out box mechanisms 12 with guides 101, wherein the guides 101 include the substantially horizontal portion 103 and the upturned portion 104, but do not include the downturned portion 111. Due to the downturned portion 111, the second carrier of the second-type storage device in the second deployed position is positioned further forward and downward, while the first carrier of the first-type storage device, lacking the downturned portion 111 in the guide 101, does not drop as low in the first deployed position. This configuration not only achieves the goal of presenting the first and second carriers at an appropriate height for order retrieval, but also offers the advantage of similar design for the first and second-type storage devices. The only differences are that the guide member 101 of the second type of storage device includes a downwardly bent portion 111, while the guide member 101 of the first type of storage device does not, and that the second type of storage device includes an arm 118 with the moving member 105 located at the distal end of the arm 118, while the first type of storage device has the moving member 105 located on the body of the first carrier 100. The similarity between the first and second types of storage devices results in a simpler design with fewer unique parts, which in turn results in a simpler carrier design and lower cost.
[0079] In some embodiments, the carrier 100 can be configured for automated loading, such as for automated loading or unloading of goods from a warehouse directly into the carrier. For example, orders in storage containers can be loaded into the carrier on the carrier at the warehouse, and the carrier can return to the warehouse after the order has been delivered, unloading the empty storage container from the carrier. To facilitate loading and unloading, Figure 8 The illustrated carrier 100 includes a front face 112 that can be lifted upward to provide access to the interior of the carrier 100 from the front. The front face 112 includes a pair of opposing flanges 113 that extend substantially perpendicular to the plane of the front face 112. Each of the opposing flanges is pivotally connected to a side wall of the carrier 100 by a pivot 114. The pivots enable the front face 112 to be rotated upward, providing unobstructed access to the interior of the carrier 100. Automated loading is particularly convenient for warehouses that use standard-sized storage containers.
[0080] In other embodiments, storage containers may be manually loaded into the carrier 100 as the front face 112 is lifted upward.
[0081] In such Figures 1 to 3 In the illustrated embodiment where the rows of storage devices are arranged on the sides of the vehicle, cargo or storage containers may be loaded or unloaded from the sides of the vehicle.
[0082] Although the front face 112 that can be lifted upward for manual loading / unloading or automatic loading / unloading is shown as being applied to a specific embodiment of the tilting pull-out box mechanism, this feature can also be used with other embodiments of the tilting pull-out box mechanism and / or the pull-down pull-out box mechanism, and / or other embodiments of the first type of storage device or the second type of storage device.
[0083] Figure 18 Schematically shows the two reference Figures 4 to 8 The two tilting pull-out box mechanisms share the outer shell 124 of the support guide 101. One or more units can be installed alone or in combination with other types of storage devices on the same Figures 1 to 3 On a vehicle similar to the one shown.
[0084] Both carriers 100 have a removable front face 112 to facilitate loading and unloading. Figure 18 The front face 112 is shown with Figure 8 The differences in the front shown are: Figure 18 The front face is shown pulled downward (rather than lifted upward) to provide access to the interior of the carrier 100 from the front of the carrier 100. The front face 112 is pivotally connected to the side walls of the carrier 100 by pivots 114. The pivots allow the front face 112 to be rotated downward, providing unobstructed access to the interior of the carrier 100.
[0085] This feature of the front 112 being movable relative to the carrier 100 can be applied to any embodiment of a tilting pull-out box or a pull-down pull-out box. In any embodiment described herein, or in other embodiments, the front 112 can be pulled downward (e.g., Figure 18 As shown), lift up (as shown Figure 8 as shown), or otherwise move relative to the carrier 100.
[0086] Figure 19 Schematically shows both carriers 100 in the deployed position Figure 18 . It can be seen that the volumes of space occupied by the two carriers 100 when in the deployed position slightly overlap. In other embodiments, the volumes of space occupied by the carriers 100 when in the deployed position may not overlap, or the volumes of space occupied by the carriers 100 may overlap at some point along the path between the stowed position and the deployed position.
[0087] Figure 20Schematically shows Figure 18 Components of the tilting drawer mechanism 12 in FIG. 1 are shown in (a) a side view from the inside of the outer shell, (b) a side view from the outside of the outer shell, and (c) a perspective view. The components include a guide 101 and an additional chain guide 125 . Figure 20 In (a), the horizontal portion 103 and the upturned portion 104 of the guide 101 are marked.
[0088] In this embodiment, the chain is guided by the guide 101 and the chain guide 125. Figure 5 , in which a single guide 101 serves as both a guide for the moving member and a guide for the chain, and is also different from the second embodiment of the tilting drawer mechanism (as discussed later, in which the guide comprises a slideway and the chain is guided by a separate chain guide).
[0089] The chain guide 125 is Figure 20 (b) shows an opening on one side (outside) and Figure 20 (a) shows a partially shielded channel on the other side (inside). This arrangement has the advantage that the chain is shielded from view from the inside of the outer shell 124, rather than exposed, thereby reducing the risk of any other components becoming stuck on the chain. Advantageously, in the storage position, the moving part is behind the guide 101, so that the chain is substantially contained within the chain guide 125 in a controlled / constrained manner, improving reliability. This arrangement is compared to Figure 5 and Figure 8 An advantage of the illustrated embodiment is that the chain is constrained within the chain guide 125 rather than being housed in a less constrained manner within the container 109 .
[0090] A chain (not shown for clarity) passes along chain guide 125, around sprocket 108 at the rear of the unit, and back along guide 101. Sprocket 108 is rotated by motor 117. To move the carrier 100 from the stowed position to the deployed position, sprocket 108 rotates and pushes the chain along guide 101, thereby moving the carrier 100 forward. As the chain is pushed along guide 101, the chain is pulled along chain guide 125. To retract the carrier 100 from the deployed position to the stowed position, sprocket 108 rotates in the opposite direction and pulls the chain back along guide 101, thereby moving the carrier 100 rearward. As the chain is pulled along guide 101, the chain is pushed along chain guide 125. Guide 101 and chain guide 125 constrain the chain so that the chain remains rigid enough to be pushed as well as pulled. From Figure 20 As can be seen in the diagram, the chain guide 125 is shaped so that there is a portion at the front where the direction is reversed. This allows ample space to accommodate the full length of the chain when the carrier is in the storage position.
[0091] In some embodiments, the delivery vehicle can be used for the delivery of refrigerated or frozen goods, such as groceries. A pull-out box with insulation and / or eutectic elements can be used to keep the goods at a low temperature for a period of time. Figure 21 Schematic illustration of (a) a drawer box or carrier 100 with insulated side walls, and a cover 130, eutectic plates 132, and plate holder 133 for the carrier in (b) exploded view and (c) assembled view. Figure 21 As can be seen in (a), the carrier 100 has thick side walls 122, a front face 112, a back face and a bottom to accommodate the insulation material.
[0092] like Figure 21 (b) and Figure 21 As shown in (c), a cover 130 is provided to cover the opening of the carrier 100 and provide additional insulation and cooling. The cover 130 is attached to the outer shell 124 by any suitable fastening means (not shown). Figure 21 As can be seen in FIG, both the carrier and the lid have angled edges. The angled edges facilitate movement of the carrier between a stowed position, in which the lid 130 engages the carrier 100, and a deployed position, in which the carrier is open at the top to provide access to the interior of the carrier 100, with the lid 130 remaining attached to the outer shell 125. The edges of the carrier 100 and / or lid 130 may be provided with seals so that when in the stowed position, the lid 130 forms a seal with the carrier 100 to maintain the temperature inside the carrier 100. Any suitable seal, such as a rubber seal, may be used.
[0093] The lid 130 also includes insulating material and a cavity 131 on its underside for accommodating a eutectic plate 132. The eutectic plate 132 is secured in place by a plate holder 133 that is receivable within the cavity 131. The plate holder 133 takes the form of a shallow tray upon which the eutectic plate 132 rests. Holes in the plate holder 133 ensure that air within the carrier 100 can pass through the holes and flow through the eutectic plate 132, thereby cooling the air within the carrier 100. The plate holder 133 is removably attached to the lid 130 by means of hinges 134. In this embodiment, the hinges are formed by two hook-like protrusions on the plate holder 133 that hook onto horizontally extending rods within the cavity 131. The plate holder 133 is secured to the lid 130 using suitable fastening means 135, which may be, for example, magnets or snaps.
[0094] As mentioned above Figure 18As described above, the front face 112 of the carrier 100 can be pulled downward. This arrangement is particularly advantageous in embodiments where the carrier is provided with a lid 130 having a eutectic plate 132, because opening the front face 112 allows for convenient access to the lid 130 when the carrier 100 is in the storage position. The front face 112 can be provided with a latch mechanism to hold the front face 112 in the closed position.
[0095] In use, to replace the eutectic plate 132 (e.g., before the delivery vehicle departs on a delivery route), the front face 112 can first be unlocked and pulled downward to access the interior of the carrier 100. If storage containers or other cargo are present in the carrier 100, they may need to be removed to access the bottom portion of the lid 130. The fastening means 135 are released, and the plate carrier 133 is pivoted downward about the hinge 134 so that the eutectic plate 132 can be removed and replaced with a new one. The plate carrier with the new eutectic plate is then moved back into the cavity 131 of the lid 130 and secured by the fastening means 135. The front face 112 can then be locked into the closed position, and the storage container or other cargo can be replaced or otherwise inserted into the carrier 100.
[0096] Figure 21 The specific embodiment shown is not intended to be limiting, and other suitable insulation arrangements and / or one or more eutectic elements may also be used. This feature of securing the eutectic element and / or the cover to the outer shell may be applied to any embodiment of the tilt-type pull-out box or the pull-down pull-out box. Inclined drawer mechanism - Second embodiment
[0097] exist Figure 9 In another embodiment shown in (ad), the tilting drawer mechanism 12 includes a carrier 100 and slides 120 that guide the carrier 100 in a substantially horizontal direction between a storage position and a deployed position. Two sets of slides are provided on opposite sides of the tilting drawer mechanism 12.
[0098] As with the first embodiment, the carrier 100 is in the form of an open box, in the shape of a cube, with a bottom and four side walls, and open at the top. In other embodiments, the carrier 100 can take different forms, such as a tray or a shelf, or a box with a removable cover.
[0099] The distal end 121 of the slide is pivotally connected to a side wall 122 of the carrier 100 via a pivot 123. The pivot 123 allows the carrier 100 to rotate relative to the slide 120.
[0100] When being in the storage position, the carrier 100 is received in the outer shell 124, and this outer shell 124 adopts the form of the side open type box or passage with bottom, top and two side walls.When being in the expanded position, the carrier 100 is basically outside the outer shell 124.When the carrier 100 is in the outer shell 124, the outer shell 124 is limited to the movement of the carrier 100 along the linear horizontal movement of the outer shell 124 axis, and limits the rotation movement of the carrier 100.When the carrier 100 is basically outside the outer shell 124, the carrier 100 is no longer limited by the outer shell 124, and therefore can be tilted downward / forward with respect to the angle of the horizontal plane.In other embodiments, the carrier 100 can tilt upward, rather than tilt downward.
[0101] Figure 9 (a) shows the carrier 100 in the storage position and completely within the outer shell 124. The outer shell 124 prevents the carrier 100 from rotating. Figure 9 (b) shows the carrier 100 in an intermediate position and partially within the outer shell 124. Again, the outer shell 124 prevents the carrier 100 from rotating. Figure 9 (c) shows the carrier 100 in the deployed position. The carrier 100 is mostly outside the outer shell 124 and is therefore no longer prevented from rotating. Figure 9 (d) shows the carrier 100 in the deployed position and tilted downward. The degree of rotation of the carrier 100 is limited by the outer shell 124, particularly the bottom of the outer shell 124. The carrier 100 tilts forward until the bottom of the tilted carrier 100 rests on the bottom of the outer shell 124.
[0102] As with the first embodiment of the tilting drawer mechanism 12, the movement of the carrier 100 can be automated, for example, by using a chain mechanism. The chain mechanism (as described above with reference to the first embodiment of the tilting drawer mechanism 12, and as described above with reference to the first embodiment of the tilting drawer mechanism 12) can be automated. Figure 5 (as shown in (ac)) can also be applied to the second embodiment of the inclined drawer box mechanism 12.
[0103] Figure 16 (a and b) illustrate side views of the tilting drawer mechanism 12 with a separate chain guide 125. Unlike the first embodiment of the tilting drawer mechanism 12 (in which the guide 101 also serves as the chain guide), the chain guide 125 in the second embodiment is a separate component. The chain guide 125 is provided to guide the chain 110, as described above for the first embodiment, enabling the chain 110 to both push the carrier 100 from the storage position to the deployed position and pull the carrier 100 from the deployed position back to the storage position. As with the first embodiment of the tilting drawer mechanism, the chain guide 125 constrains the chain 110, ensuring that it is rigid enough to push and pull the carrier 100.
[0104] The distal end of the chain 110 is connected to Figure 16 Connector 128 is shown as a dashed box in (a and b). The chain engages with sprocket 129. Connector 128 is attached to the rear side of the carrier 100. When the carrier 100 is between the stowed position and the intermediate position, connector 128 is constrained to slide within chain guide 125, thereby also helping to guide the carrier 100. When the carrier 100 pivots downward from the intermediate position to the deployed position, connector 128 moves away from the front end of chain guide 125, allowing the carrier 100 to pivot downward. To retract the carrier 100 from the deployed position to the stowed position, sprocket 129 is rotated to pull the chain 110 back. This also pulls the connector 128 attached to the distal end of the chain 110 back until the connector 128 reengages the front end of the chain guide 125 when the carrier 100 reaches the intermediate position. Further rotation of the sprocket 129 pulls the connector 128 back along the chain guide 125, thereby retracting the carrier 100 to its storage position.
[0105] Figure 16 (a) shows the carrier 100 in the stowed position with the chain 110 fully retracted. The carrier 100 is fully within the outer shell 124 and the slides 120 are in the retracted position. The connector 128 is enclosed within the chain guide 125.
[0106] Figure 16 (b) shows the carrier 100 in the deployed position, with the chain 110 fully extended. The chain 110 passes through the entire chain guide 125 and extends out the front of the chain guide 125. The connector 128 is outside the chain guide 125, and the carrier 100 has been tilted forward about the pivot point 123 on the slide 120. The slide 120 is in the fully extended position.
[0107] Figure 17 Shown Figure 16 1 shows a different view of the tilting drawer mechanism 12 in FIG. 1 , wherein the sides of the carrier 100 and most of the outer shell 124 have been removed for ease of viewing. The connector 128 can be clearly seen engaging the chain guide 125. In the figure, the carrier 100 is in the storage position.
[0108] Figure 17 Also shown are support rails 126 extending over roller bearings 127. The support rails 126 and bearings 127 support the carrier 100 so that the slides 120 and chain guides 125 do not need to support the entire weight of the carrier 100 and any cargo / items it contains. The support rails 126 also help guide the movement of the carrier 100 in a horizontal direction between the storage position and the intermediate position. Figure 17The support rail 126 shown is a single support rail disposed in the middle of the carrier 100. The support rail 126 is fastened to the bottom side of the carrier 100 and is supported by an elongated roller bearing 127. Although only one roller bearing 127 is shown, in practice, there may be a series of roller bearings 127 distributed between the front and rear portions of the outer shell 124 so that the support rail 126 is supported by two or more bearings as the carrier 100 moves between the storage position and the intermediate position.
[0109] Two chain guides 125 with two chains 110, two connectors 128 and two sprockets 129 are provided on opposite sides of the carrier 100 to ensure stability and to distribute the weight of the carrier 100 more evenly. Figure 17 For clarity, only one side of the chain guide 125 and the connecting member 128 are shown. The sprocket 129 is mounted on the shaft 130 and is located behind the back of the outer shell 124. The shaft 130 can be driven by the motor 117 (shown in FIG. Figure 16 The two sprockets are mounted on the same shaft 130, which means that the two chains 110 on opposite sides of the carrier 100 are pulled with equal force, thereby ensuring the stability of the tilt-type drawer mechanism as the carrier 100 moves between the storage position, the intermediate position and the deployed position. Pull-down drawer mechanism
[0110] exist Figure 3 In the embodiment shown, the second type of storage device 22 is a pull-down box mechanism including a carrier 200, wherein the carrier 200 is configured to move outward and downward relative to the carrier 1 and then tilt. Although the carrier 200 is tilted downward in the embodiment shown, in other embodiments, the carrier 200 can be tilted upward. Although the carrier 200 is described as a "pull-down box mechanism", it is not limited to a pull-out box. Figure 10 In the embodiment shown, the carrier 200 takes the form of an open box, is in the shape of a cube, has a bottom and four side walls, and is open at the top. In other embodiments, the carrier 200 can take different forms, such as a tray or a shelf, or a box with a removable cover.
[0111] Figure 10is a schematic diagram of a possible embodiment of a pull-down drawer mechanism 22. In the illustrated embodiment, carrier 200 is configured to move outward and downward from its closed position (storage position) to its open position (deployed position). In the deployed position, carrier 200 is substantially outside the footprint of carrier 1 and is also tilted downward so that carrier 200 is presented at an angle relative to the horizontal. The low height and tilted angle mean that the contents of carrier 200 are easily accessible, eliminating the need to lift potentially heavy items from great heights (which could create a risk of them falling).
[0112] In the illustrated embodiment, the pull-out box mechanism 22 includes a carrier 200 and an outer shell 201. When in the storage position, the carrier 200 is housed within the outer shell 201. The outer shell 201 takes the form of an open-sided box with three side walls and a top. In other embodiments, the carrier 200 and the outer shell 201 may take different forms. For example, the outer shell may be a shelf on which the carrier 200 rests when in the storage position.
[0113] In the illustrated embodiment, the carrier 200 is connected to the outer shell 201 via two pairs of links. A first link 202 is pivotally connected to the outer shell 201 at a first end 203 and to the carrier 200 at a second end 204. A second link 205 is pivotally connected to the outer shell 201 at a first end 206 and to the carrier 200 at a second end 207. The first link 202 is straight, and the second link 205 is curved. The curved shape of the second link 205 prevents the second link 205 from interfering with the first link 202 when the carrier 200 is moved to the deployed position. While the second link 205 is curved in this particular embodiment, any other shape (e.g., an angled shape) that achieves the same purpose may be used.
[0114] In order to ensure stability and a more uniform force distribution, a pair of first links 202 and a pair of second links 205 are provided in the illustrated embodiment, with one first link 202 and one second link 205 attached to each side of the carrier 200 .
[0115] Figure 11 (af) are schematic diagrams of the carrier mechanism 22 viewed from the side in different positions. Figure 10Similarly, carrier 200 is connected by two links—a first link 202 and a second link 205. As will be described in further detail below, the second link is curved. Small circles 203, 204, 206, and 207 represent pivot points located at the first end 203 and the second end 204 of first link 202, and at the first end 206 and the second end 207 of second link 205. The bold horizontal line 208 is the bottom, which may represent a shelf or portion of the outer shell of the carrier. When in the storage position, carrier 200 rests on bottom 208.
[0116] Since the lengths of the links are fixed, the paths or trajectories of the second end 204 of the first link 202 and the second end 207 of the second link 205 are circular. The second end 204 of the first link 202 follows a first path, which is a portion of a circle 209 centered at the first end 203 of the first link 202. The second end 207 of the second link 205 follows a second path, which is a portion of a circle 210 centered at the first end 206 of the second link 205. Figure 11 The large circles 209, 211 in the figure represent the paths or trajectories of the second ends 204, 207 of the first link 202 and the second link 205, respectively.
[0117] exist Figure 11 In (a), the carrier 200 is in the storage position and rests on the base 208. Figure 11 In (b), the carrier 200 has moved part way along its circular path 209, 210 and is at a vertical level below the storage position. Figure 11 In (c), the carrier 200 moves further along its circular path 209, 210 and descends further, with the first link 202 and the second link 205 being almost horizontal. Figure 11 (a) Figure 11 (b) and Figure 11 In (c), the two pivot points at the second ends 204, 207 of the first link 202 and the second link 205, respectively, are located at the same vertical level, and thus, the carrier 200 remains horizontal.
[0118] In this specification, "horizontal plane" refers to the horizontal plane in which the bottom of the carrier 200 lies when the carrier 200 is in the storage position. This plane coincides with the horizontal plane in which the bottom 208 lies. When the links 202, 205 are described as being "below the horizontal plane," this term indicates that the second ends 204, 207 are at a lower vertical level than the first ends 203, 206. That is, when the second end 204 of the first link 202 is vertically below the first end 203 of the first link, the first link 202 is below the horizontal plane, and when the second end 207 of the second link 205 is vertically below the first end 206 of the second link, the second link 205 is below the horizontal plane.
[0119] As the links 202, 205 rotate further and the carrier 200 descends below the horizontal plane, there are two positions where the geometric constraints imposed by the particular arrangement of the links as shown are satisfied. The first geometric constraint is that the two pivot points at the second ends 204, 207 of the first and second links 202, 205, respectively, must be a fixed distance from the first ends 203, 206 of the first and second links 202, 205, respectively, i.e., the distance is fixed by the length of the links 202, 205, and the second ends 204, 207 are constrained to follow a circular path or trajectory 209, 210, respectively. The second geometric constraint is that since the two ends are pivotally connected to the carrier 200, the distance between the two pivot points at the second ends 204, 207 of the first and second links 202, 205, respectively, (in Figure 11 (x) in (df) is fixed. When the links 202, 205 are lowered below the horizontal plane, for a given position of the pivot point 207 at the second end of the second link 205, there are two possible positions of the pivot point 204 at the second end of the first link 202. These two positions are Figure 11 (df) are labeled 211 and 212, also referred to as upper position 211 and lower position 212. As can be seen from the figure, both positions 211 and 212 are located on the circular path or trajectory 209 of the first link 202, and the distance between each of the two positions 211 and 212 and the pivot point 207 at the second end of the second link 205 is x. Therefore, the pivot point 204 at the second end of the first link 202 can occupy either position 211 or position 212 while satisfying the geometric constraints imposed by the fixed lengths of the links 202, 205 and the fixed distance x between the two pivot points 204, 207 at the first ends of the two links 202, 205.
[0120] Figure 11 (d) shows the position of the carrier 200 below the horizontal plane, with the pivot point 204 at the second end of the first link 202 in a lower position 212. The pivot point 204 in the lower position 212 is at a lower vertical level than the pivot point 207 at the first end of the first link 205. Thus, the carrier 200 is tilted downward.
[0121] Figure 11(e) shows the position of the carrier 200 below the horizontal plane, with the pivot point 204 at the second end of the first link 202 in the upper position 211. As can be seen from the figure, although the upper position 211 satisfies the geometric constraints, the two links 205 and 202 still collide, and with the link configuration as shown, the carrier 200 cannot remain horizontal and tilts downward, causing the pivot point 204 at the second end of the first link 202 to occupy the lower position 211.
[0122] Even if the first link 202 bends in the opposite direction, i.e., its shape is designed to avoid collision with the second link 205, the weight of the carrier 200 will still pull the drop-down carrier 200 downward, causing the pivot point 204 at the second end of the first link 202 to occupy a lower position 212 rather than a higher position 211.
[0123] The curved shape of the second link 205 is necessary so as not to interfere with the first link 202 when the link is rotated downward below the horizontal plane. Figure 11 As shown in FIG. 5( f ), if the second link 205 were a straight member rather than a curved member, the links would not be able to move below the horizontal plane because the first link 202 would obstruct the movement of the second link 205. Although the second link 205 is shown as having a curved shape in this embodiment, any shape that allows the first link 202 to rotate downward without obstructing the first link 202 is applicable.
[0124] Figure 12 Another embodiment of a pull-down box mechanism 22 is shown. In this embodiment, the first link 202 is angled and includes two substantially straight sections, and the second link 205 is curved. The angled shape of the first link 202 serves two purposes: the shorter, straight section of the first link 205 rests on the bottom 208 of the outer shell 201, and the curved second link 205 rests on the angled second link at two points of contact (rather than a single point of contact as would be the case if the first link were straight). The two points of contact make the pull-down box mechanism 22 more stable because the weight of the carrier 200 and any contents therein is more evenly distributed across the links 202, 205, rather than having all the weight concentrated in one single point.
[0125] While in the illustrated embodiment, the two links 202, 205 are arranged at the same horizontal level (i.e., the first ends 203, 206 of the links 202, 205 are at the same horizontal level, and the second ends 204, 207 of the links are at the same horizontal plane, except when the links are lowered below the horizontal plane), in other embodiments, the links may be positioned differently. For example, the first ends of the links may be vertically offset, i.e., the first end of the first link may be positioned at a lower vertical level than the first end of the second link. Of course, other arrangements are also possible. In some embodiments, it may not be necessary to shape one of the links so that the two links do not interfere with each other when the carrier 200 is lowered and tilted forward.
[0126] Figure 13 (ad) shows an embodiment where both links 202, 205 are straight and tilting is achieved by vertically offsetting the links. The first end 203 of the first link 202 is fixed at a lower vertical level than the first end 206 of the second link 205. Figure 10 、 Figure 11 and Figure 12 The embodiment shown is different. Figure 13 In the embodiment of FIG. 1 , the carrier 200 tilts as it descends, rather than remaining horizontal until the carrier 200 has moved as far downward as it can and then tilting downward to the deployed position. The first end 203 of the first link 202 is at a lower level so that the two links 202, 205 can pivot downward below the horizontal plane and tilt the carrier 200.
[0127] exist Figure 13 In (a), the carrier 200 is shown in the stowed position with the cover 213 covering the top of the carrier 200. This provides an additional layer of security. The cover 213 can be provided as part of the outer shell 201 (not shown). The cover 213 must be opened in order to move the carrier 200 to the deployed position. Figure 13 (b) shows the carrier 200 in the storage position with the lid 213 open. Figure 13 (c) shows the carrier 200 in an intermediate position between the stowed position and the deployed position. As can be seen, the carrier 200 is tilted slightly forward. Figure 13 (d) shows the carrier 200 in the deployed position. The first link 202 is rotated slightly below the horizontal plane, and the second link 205 is rotated just above the horizontal plane. The links are prevented from rotating further because the second link 205 rests on the second end 203 of the first link 202 and is therefore prevented from rotating further. The carrier 200 is tilted forward.
[0128] The cover 213 at the top of the carrier 200 effectively separates the display of the cargo / items within the carrier 200 from the security of the carrier 200. The cover 213 provides security for the pull-down drawer mechanism 22, not only preventing unauthorized access to the contents of the carrier 200 when the carrier 200 is in the stowed position, but also preventing the carrier 200 from moving from the stowed position to the deployed position. The path of the carrier 200 between the stowed and deployed positions is as follows: the carrier 200 first moves vertically upward, out of the outer shell 201, whereupon the presence of the closed cover 213 prevents the carrier 200 from moving to the deployed position. The cover 213 also enables more efficient use of storage space within the carrier, as sufficient clearance is not required to allow the tilting drawer mechanism 12 to begin deployment when the flap doors 40 are closed. Because the cover 213 provides security for a single storage device, there is no risk of unauthorized access to other storage devices remaining in the stowed position.
[0129] The link arrangements shown in the figures are examples only, and other combinations of bent, angled, or straight links may be used, including links that are vertically offset at their first, second, or both ends. In general, the lengths and shapes of the first and second links 202, 205 and the positions of the first and second ends 203, 206, 204, 207 may be varied to define the path the carrier takes between the stowed and deployed positions.
[0130] In a manner similar to the tilting drawer mechanism 12 described above, the movement of the pull-down drawer mechanism 22 can be automated. For example, the first link 202 and / or the second link 205 can be driven by motors at the first ends 203 and 207 of the links 202 and 205. In some cases, a gearbox can be used to reduce the speed of the motors. Alternatively, the pull-down drawer mechanism 22 can include an actuator arm configured to drive the carrier 200 between the stowed position and the deployed position. The length of the actuator arm can be changed using a lead screw. Alternatively, one or more linear motors can be used to push / pull the first link 202 and / or the second link 205 and / or the carrier 200. Gas struts (gas pressure dampers) can be used to bear part of the weight of the carrier 200 and any cargo therein, so that the motor(s) are subjected to less force, thereby allowing for lower specifications and lower costs. Alternatively, actuation may be achieved by a large gear driven by a small gear (driven by one or more motors).Any combination of the above actuation mechanisms or other suitable actuation mechanisms may be used. Other arrangements of storage devices
[0131] exist Figures 1 to 3In the illustrated embodiment, the carrier 1 has four first-type storage devices 12 in a first row 11 and four second-type storage devices 22 in a second row 21. The number of first-type storage devices 12 in the first row 11 is equal to the number of second-type storage devices 22 in the second row 21, and the first-type storage devices 12 and the second-type storage devices 22 are arranged such that each second-type storage device 22 in the second row 21 is vertically positioned above its respective first-type storage device 12 in the first row 11. The first-type storage devices 12 and the second-type storage devices 22 are of equal size. In other embodiments, the number and size of the first-type storage devices 12 and the second-type storage devices may differ.
[0132] Figure 14 (ac) show some other possible arrangements of storage devices on the carrier. Figure 14 In (a), the first row 11 includes a greater number of first type storage devices 12 than the second row 21 includes second type storage devices 22. Figure 14 In (b), the second type storage devices 22 in the second row 21 are horizontally offset relative to the first type storage devices 12 in the first row 11, so that each second type storage device 22 is not directly above a single first type storage device 12. Figure 14 In (c), the first type of storage devices 12 in the first row 11 are larger and fewer in number than the second type of storage devices 22 in the second row 21. An arrangement with storage devices of different sizes may be useful where order sizes vary significantly, i.e., smaller storage devices may be used for smaller orders of a single item or a small number of items, while larger storage devices may be used for larger orders (e.g., grocery orders) or orders containing larger items.
[0133] In some embodiments, the first row of one or more first type storage devices includes two first rows arranged on opposite sides of the carrier, and the second row of one or more second type storage devices includes two second rows arranged on opposite sides of the carrier.
[0134] In some embodiments, as an alternative or in addition to being arranged on the sides of the vehicle, the first and second rows can be arranged at the front and / or rear of the vehicle. In the case of an autonomous vehicle, there is no need for "crash buffers" at the front and rear of the vehicle since there is no driver or passengers. This allows the front and rear areas to be used for further storage. In some embodiments, the vehicle does not have a clear front and rear end and can be driven in either direction. In some embodiments, the wheels of the vehicle can change direction so that the vehicle can be driven in any direction, not just forward or backward. In these embodiments, by placing rows of storage devices on any or all sides of the vehicle, the design freedom of the vehicle is increased and better utilization of storage space on the vehicle can be achieved.
[0135] In some embodiments, as Figure 15 As shown in (a and b), the carrier can be provided with more than two rows of storage devices. For example, the carrier can further include a third row 31 of third type storage devices 32 positioned vertically below the first type storage devices 12 in the first row 11. The third type storage devices 32 can be the same as the first type storage devices 12 and / or the second type storage devices 22, or they can be different types of storage devices. The number of third type storage devices 32 in the third row 31 can be equal to or different from the number of first type storage devices 12 in the first row 11 and / or the number of second type storage devices 22 in the second row 21. Each third type storage device 32 in the third row 31 can be positioned vertically below its respective first type storage device 12 in the first row 11, or can be horizontally offset relative to the first type storage device 12.
[0136] exist Figure 15 In (a), the number of third type storage devices 32 in third row 31 may be equal to the number of first type storage devices 12 in first row 12, and equal to the number of second type storage devices 22 in second row 21. The storage devices are arranged such that each third type storage device 32 in third row 31 is vertically located below a respective first type storage device 12 in first row 11, and each first type storage device 12 in first row 11 is vertically located below a respective second type storage device 22 in second row 21.
[0137] exist Figure 15 In (b), the third type of storage devices 32 in the third row 31 are located within the wheelbase of the vehicle 1, i.e., in the space between the front and rear wheels of the vehicle 1. This arrangement is advantageous because it makes efficient use of the available space within the vehicle 1.
[0138] In some embodiments, the volume of space occupied by the third carrier of one of the third type storage devices 33 when in the third deployed position is at least a fraction of the volume of space occupied by the first carrier of one of the first type storage devices 12 when in the first deployed position. For example, the third type storage devices can be configured to move outward and upward so that the third deployed position is at a higher vertical level than the third storage position.
[0139] In other embodiments, the carrier may be provided with more rows of storage devices, such as a fourth row. Depending on the size and shape of the carrier and the size and shape of the storage devices, the carrier may have any number of rows of storage devices, with any number of storage devices in each row. Vehicle Access
[0140] In some of the embodiments shown above, the first type of storage device 12 includes an outer shell 124 that receives the first carrier when the first carrier is in the first storage position. Similarly, in some of the illustrated embodiments, the second type of storage device 22 includes an outer shell 202 that receives the second carrier 200 when the second carrier 200 is in the second storage position.
[0141] Although in the illustrated embodiment, each storage device has its own housing (ie, each first type storage device 12 includes a housing 124 and each second type storage device 22 includes a housing 201), in other embodiments, multiple storage devices may be received within the same housing.
[0142] In some embodiments, the outer shell of one or more storage devices of the first type of storage device and / or the second type of storage device may include a door configured to prevent access to the carrier when the carrier is in the storage position and received within the outer shell. When access to the carrier is required, the door may be opened to allow the carrier to be moved to the deployed position to remove cargo / items from the carrier. For example, Figure 13 The cover 213 shown for the tilting drawer mechanism 22 is a door and may be provided as part of the outer housing 201 .
[0143] In some embodiments, the door may include a locking mechanism to prevent or allow access to individual storage devices on the carrier. Advantageously, the locking mechanism ensures that only authorized access is possible. For example, a customer may be provided with a physical key or key code to unlock the door(s) of the storage device(s) containing their order, thereby allowing the customer to access the storage device(s) containing their order without accessing any other storage devices.
[0144] In a more complex system, the carrier may further include a control system configured to selectively operate the locking mechanism to allow one or more doors to be opened, thereby providing access to one or more of the first type of storage device and / or the second type of storage device. For example, an access code may be sent to a customer's mobile device, which the customer then enters to retrieve their order. Upon receiving the correct access code, the control system instructs the locking mechanism to unlock the corresponding door, thereby enabling the customer to retrieve their goods from the corresponding storage device.
[0145] In some embodiments, the carrier may be provided with a display to provide information about the customer's order (e.g., a list of all products in the order, the customer's name, whether any items are out of stock and require replacement). In some embodiments, the display may include a graphical user interface to enable the customer to interact with the storage system to retrieve their order from one or more lockers (e.g., by entering an access code). The graphical user interface may include one or more input devices, such as a keyboard, mouse, trackpad, or touch screen, for the customer to make selections.
[0146] In some embodiments, sensors can be used to detect information about the customer. For example, a proximity sensor can be used to detect when a customer approaches the vehicle, and the graphical user interface can respond by displaying a welcome message. One or more cameras can be mounted on the vehicle along with the display. The one or more cameras can be used to identify the customer using facial recognition technology. The display can then display a personalized welcome message for the customer. Information specifically tailored to the customer can be displayed, such as special offers or product recommendations.
[0147] Facial recognition technology can also be used to identify the customer and open the door(s) of the storage unit(s) containing the customer's order. For example, one or more cameras can be used to identify the customer, and the control system will instruct the locking mechanism to only open the door(s) of the storage unit(s) containing the customer's order. If the facial recognition technology does not identify a person approaching the vehicle, the control system ensures that the locking mechanism is activated to keep the door locked.
[0148] When a customer has removed their goods from the storage device, or when the customer stops interacting with the graphical user interface, the control system can be configured to automatically close the door(s) of the storage device and subsequently activate a locking mechanism to lock the door(s). One or more cameras or proximity sensors can be used to determine if the customer has exited the vehicle, even if the customer has not yet retrieved their goods. Once the interaction ends (whether completed or aborted), the control system can direct the door(s) to close and lock, preventing access to the goods in the storage device.
[0149] In some embodiments, for example Figures 1 to 3 In the illustrated embodiment, the storage devices within the carrier 1 are enclosed by a carrier housing 41. The carrier housing 41 surrounds the storage devices to prevent unauthorized access and provide an additional layer of security. In some cases, the outer housings of the storage devices may be enclosed by the carrier housing, while in other cases, one or more of the outer housings of the storage devices may form part of the carrier housing. One or more carrier doors 40 may be used to allow access to the storage devices within the carrier.
[0150] exist Figures 1 to 3In the illustrated embodiment, the carrier housing 41 has a pair of carrier doors 40 configured to allow access to the first type storage devices 12 and the second type storage devices 22 for retrieval of orders from the carrier 1. In the illustrated embodiment, the carrier doors 40 are a pair of wing doors, with a separate wing door on each side of the carrier 1. In other embodiments, the carrier 1 may be provided with a single door or a greater number of doors. In the illustrated embodiment, the carrier doors 41 are used for loading and unloading cargo onto the carrier 1 and for retrieval of orders from the first type storage devices 12 and the second type storage devices 22.
[0151] Vehicle 1 is effectively a dual-sided storage system, with storage devices accessible from opposite sides of vehicle 1. A first row 11 of first-type storage devices 12 and a second row 21 of second-type storage devices 22 are accessible from one side of vehicle 1, while another first row 11 of first-type storage devices 12 and another second row 21 of second-type storage devices 22 are accessible from the opposite side of vehicle 1. Having storage devices 12 and 22 accessible from both sides of vehicle 1 offers the advantage of allowing simultaneous access to storage devices on both sides of the vehicle. This is particularly useful in embodiments where the vehicle has a high order throughput or where a single order is large and occupies several storage devices 12 and 22. Another advantage of having both first-type storage devices 12 and second-type storage devices 22 accessible from both sides is that vehicle 1 can be parked on either side of the road to facilitate order retrieval. If the control system knows in advance which side of the vehicle contains a particular order, the vehicle can be parked so that the storage device or devices containing the corresponding order are adjacent to the sidewalk, facilitating retrieval.
[0152] The vehicle 1 includes a vehicle chassis including wheels driven by a drivetrain powered by, for example, an internal combustion engine and / or an electric motor, thereby enabling the vehicle to move. A vehicle housing 41 can be configured to be removably mounted on the vehicle chassis, or the vehicle housing 41 can be integrally formed with the vehicle chassis. The vehicle housing 41 includes side walls and a top wall, as well as a vehicle door 40. When closed, the vehicle door 40 forms part of the vehicle housing.
[0153] Vehicles may be used to transport items from a warehouse or fulfillment center to a location where individual orders can be picked up (i.e., a "place and collect" system), and / or vehicles may be used to deliver orders to multiple different delivery addresses.
[0154] In some embodiments, the vehicle may be an autonomous vehicle. The autonomous vehicle may include one or more sensors (e.g., cameras, radar, lidar, sonar, global positioning system (GPS), etc.) and a control system configured to receive input from the one or more sensors to enable the vehicle to travel between a plurality of destinations with little or no input from a human driver. The control system may be configured to control one or more of the vehicle's speed, steering, and braking.
