Description

Technical Field

[0001] This application relates to the field of logistics pallet technology, and in particular to a pallet assembly. Background Technology

[0002] Pallets, as a basic logistics and warehousing tool, are widely used in cargo handling, stacking, and storage. Their function is to support packaged goods to improve logistics efficiency. Currently, wooden pallets are commonly used in the industry. When faced with packaged goods of varying sizes, the usual solution is to customize pallets to the specific dimensions of the packaged goods.

[0003] However, with the diversification of market demand, the size and specifications of packaged goods are becoming increasingly numerous, resulting in too many specific pallet sizes. This increases the complexity of warehouse differentiation, scheduling and management. At the same time, single-size pallets have low versatility and high idle rates, leading to resource waste.

[0025] In one embodiment, at least two second trays are provided, and the at least two second trays can be stacked and spliced ​​with the corresponding first trays;

[0026] The second pallet has a second insertion groove on one side having the second supporting surface; the second pallet also includes:

[0027] The second support leg is located on the side of the second pallet away from the second support surface, and is used to mate with the second insertion slot of the second pallet adjacent to it.

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] See Figure 1 One embodiment of this application provides a tray assembly including a first tray 10 and a second tray 20. The second tray 20 is disposed around the periphery of the first tray 10 and is spliced ​​with the first tray 10.

[0052] The first tray 10 has a first support surface 111 on its surface, and the second tray 20 has a second support surface 211 on its surface. Both the first support surface 111 and the second support surface 211 are used to support items.

[0053] By modularizing the pallet assembly, the first pallet 10 and the second pallet 20 can be flexibly spliced ​​according to the size of the items, so that the total support surface after the first support surface 111 and the second support surface 211 are connected matches the size of the items, meeting the palletizing and transportation needs of items of different sizes, improving the versatility of the pallet assembly, and reducing the number of pallet specifications, which is conducive to reducing warehouse management costs.

[0054] In one embodiment, see Figure 1 , Figure 3 and Figure 7 One of the first tray 10 and the second tray 20 is provided with a first splicing groove 112, and the other of the first tray 10 and the second tray 20 is provided with a splicing protrusion 212, which is used to interfere with the first splicing groove 112.

[0055] By using an interference fit, friction and mechanical interlock are generated between the splicing protrusion 212 and the groove wall of the first splicing groove 112. This can resist the possible loosening of the first pallet 10 and the second pallet 20, improve the firmness of the connection between the first pallet 10 and the second pallet 20, and thus ensure the stability of the pallet assembly during palletizing and transportation.

[0056] By using an interference fit, no other complex fasteners are needed, simplifying the assembly steps of the pallet assembly and improving the splicing efficiency of the pallet assembly. At the same time, it can also ensure that the splicing joint between the first pallet 10 and the second pallet 20 has sufficient strength and rigidity, so that the expanded pallet assembly forms a structurally stable whole.

[0057] See Figure 1 After the first pallet 10 and the second pallet 20 are joined, the first support surface 111 and the second support surface 211 are flush. This means that the first support surface 111 and the second support surface 211 are on the same horizontal plane. This ensures that the support surfaces of the pallet assembly are flat, guaranteeing the stability of palletized transport.

[0058] In one embodiment, see Figure 1 The area of ​​the first supporting surface 111 is larger than the area of ​​the second supporting surface 211. Optionally, the length of the first supporting surface 111 is 1.2m and the width of the first supporting surface 111 is 1m; the length of the second supporting surface 211 is 1m and the width of the second supporting surface 211 is 0.3m.

[0059] By setting the first support surface 111 to a relatively large standard size, when carrying items of regular size, the first pallet 10 can be used alone, or the first pallet 10 can be interlocked with a smaller number of second pallets 20. This reduces the number of modules to be spliced, improves splicing efficiency, and avoids structural instability of the pallet assembly due to tolerance accumulation.

[0060] In one embodiment, see Figure 3 The first pallet 10 includes a first support plate 11. A first support surface 111 is formed on the surface of the first support plate 11. Figure 3 In the middle, the upper surface of the first pallet 11 is the first supporting surface 111.

[0061] See Figure 3 The first pallet 11 has a first splicing groove 112 on at least one edge. Optionally, the first pallet 11 is square, and the first splicing groove 112 is provided on one edge of the first pallet 11; or, the first splicing groove 112 is provided on both opposite edges of the first pallet 11; or, the first splicing groove 112 is provided on both adjacent edges of the first pallet 11; or, the first splicing groove 112 is provided on three edges of the first pallet 11; or, the first splicing groove 112 is provided on all four edges of the first pallet 11.

[0062] By placing the first splicing groove 112 at the edge of the first pallet 11, a direct docking path is provided for the first pallet 10 and the second pallet 20, simplifying the splicing operation and improving splicing efficiency. At the same time, it also ensures that the splicing structure does not occupy the effective support area of ​​the first pallet 10, thus ensuring the flatness of the first support surface 111.

[0063] Furthermore, since the area of ​​the first tray 11 is relatively large, in this embodiment, the first splicing groove 112 is provided on the first tray 11. The first tray 11 can provide sufficient setting position for the first splicing groove 112, ensuring that the first splicing groove 112 has sufficient size, which is beneficial to increase the connection area between the splicing protrusion 212 and the groove wall of the first splicing groove 112, thereby improving the splicing strength and firmness of the first tray 10 and the second tray 20.

[0064] In one embodiment, see Figure 3 The first tray 11 has at least one edge with a plurality of first splicing grooves 112, which are spaced apart along the extension direction of the edge. This allows for multi-node connection with the second tray 20, providing multiple splicing position options and improving expansion flexibility, while also enhancing the overall connection strength and stability of the splicing edges by distributing stress points.

[0065] In this embodiment, see Figure 3 The first tray 11 has three first splicing grooves 112 on each of its opposite sides, and the three first splicing grooves 112 are equally spaced along the width direction of the first tray 11.

[0066] In one embodiment, see Figure 7The second pallet 20 includes a second pallet plate 21, the surface of which forms a second supporting surface 211. Figure 7 For example, the upper surface of the second support plate 21 is the second support surface 211.

[0067] See Figure 7 The splicing protrusion 212 is provided on the side of the second pallet 21. In this way, the splicing protrusion 212 is separated from the second supporting surface 211 in space, making the second supporting surface 211 flat and ensuring the stability of the pallet transport of goods.

[0068] In one embodiment, see Figure 7 The second tray 21 has multiple splicing protrusions 212 on its side, which are spaced apart along the length of the second tray 21. This allows for multi-node connection with the first tray 10, providing multiple splicing position options and improving expansion flexibility. It also improves the overall connection strength and stability of the splicing edges by distributing the stress points.

[0069] In this embodiment, the second tray 21 is square, and three splicing protrusions 212 are provided on one side of the second tray 21. The three splicing protrusions 212 are equally spaced along the length of the second tray 21.

[0070] In one embodiment, see Figure 7 The surface of the splicing protrusion 212 is flush with the second supporting surface 211. This means the surface of the splicing protrusion 212 and the second supporting surface 211 are on the same horizontal plane. This ensures a flat supporting surface for the pallet assembly, guaranteeing the stability of palletized transport.

[0071] In one embodiment, at least two second pallets 20 are provided, and the widths of the at least two second pallets 20 are different. Optionally, one second pallet 20 has a width of 0.3m, and the other second pallet 20 has a width of 0.4m. In this way, the user can flexibly select the appropriate size of the second pallet 20 to splice with the first pallet 10 according to the size of the items, effectively reducing the waste of space on the bearing surface and improving the adaptability of palletized transportation.

[0072] Of course, in other embodiments, the second pallet 20 also has a second splicing groove on one side of the second supporting surface 211. The second splicing groove is used to interference fit with the splicing protrusion 212 of the adjacent second pallet 20. If the size of the item is large, at least two second pallets 20 can be spliced ​​together so that the total supporting surface after the first supporting surface 111 and at least two second supporting surfaces 211 are connected matches the size of the item, meeting the palletizing and transportation needs of items of different sizes, improving the versatility of pallet components, and reducing the number of pallet specifications, which is beneficial to reducing warehouse management costs.

[0073] In one embodiment, see Figure 3 The first splicing groove 112 has a first opening 1123 and a second opening 1124, which are connected. The first splicing groove 112 is recessed from the side of the first tray 11 with the first supporting surface 111 in a direction away from the first supporting surface 111, so as to form the first opening 1123 on the first supporting surface 111. The first splicing groove 112 extends towards the side of the first tray 11 and penetrates the side of the first tray 11, so as to form the second opening 1124 on the side of the first tray 11. Thus, the first opening 1123 and the second opening 1124 are connected to form an L-shape. The first opening 1123 provides an introduction path, allowing the splicing protrusion 212 to fall directly along the direction of gravity. The second opening 1124 provides horizontal clearance space to avoid installation interference between the first tray 10 and the second tray 20, and also facilitates observation of whether the splicing protrusion 212 is completely embedded in the first splicing groove 112.

[0074] In one embodiment, see Figure 3 and Figure 4 The first splicing groove 112 includes a first groove 1121 and a second groove 1122. The first groove 1121 is located near the side of the first support plate 11, and the second groove opening 1124 is located on the groove wall of the first groove 1121. The second groove 1122 is located on the side of the first groove 1121 opposite to the second groove opening 1124 and communicates with the first groove 1121. The width of the first groove 1121 is smaller than the length of the second groove 1122.

[0075] It should be noted that the width of the first groove 1121 refers to the length of the first groove 1121 in a direction perpendicular to the arrangement direction of the first groove 1121 and the second groove 1122. (See reference...) Figure 4 L1 represents the width of the first groove 1121.

[0076] It should be noted that the length of the second groove 1122 refers to the maximum length of the second groove 1122 in the direction perpendicular to the arrangement direction of the first groove 1121 and the second groove 1122. (See also...) Figure 4 L2 represents the length of the second groove 1122.

[0077] Optionally, the first groove 1121 is a rectangular groove, and the second groove 1122 is a circular groove. Wherein, the width of the first groove 1121 being less than the length of the second groove 1122 means that the width of the first groove 1121 is less than the diameter of the second groove 1122.

[0078] See Figure 7 and Figure 8The splicing protrusion 212 includes a first protrusion 2121 and a second protrusion 2122. The first protrusion 2121 is located on the side of the second support plate 21. The second protrusion 2122 is located on the side of the first protrusion 2121 opposite to the second support plate 21 and is connected to the first protrusion 2121. The first protrusion 2121 is located within the first groove 1121 and is press-fitted with the first groove 1121. The second protrusion 2122 is located within the second groove 1122 and is press-fitted with the second groove 1122. The width of the first protrusion 2121 is less than the length of the second protrusion 2122.

[0079] It should be noted that the width of the first protrusion 2121 refers to its length in a direction perpendicular to the arrangement direction of the first protrusion 2121 and the second protrusion 2122. (See also...) Figure 8 L3 represents the width of the first protrusion 2121.

[0080] It should be noted that the length of the second protrusion 2122 refers to its maximum length in the direction perpendicular to the arrangement direction of the first protrusion 2121 and the second protrusion 2122. (See also...) Figure 8 L4 represents the length of the second protrusion 2122.

[0081] Optionally, see Figure 8 The first protrusion 2121 is a rectangular block, and the second protrusion 2122 is a circular block. The width of the first protrusion 2121 is smaller than the diameter of the second protrusion 2122.

[0082] Since the width of the first groove 1121 is less than the length of the second groove 1122, after the first protrusion 2121 and the second protrusion 2122 are respectively set in the first groove 1121 and the second groove 1122, the groove wall of the first groove 1121 can block the second protrusion 2122, effectively preventing the second tray 20 from shifting relative to the first tray 10, and improving the reliability of the splicing of the first tray 10 and the second tray 20.

[0083] In one embodiment, see Figure 13 The first pallet 10 is provided in at least two form, and the at least two first pallets 10 can be stacked. In use, the at least two first pallets 10 can be stacked, which increases the thickness of the pallet assembly, improves the load-bearing capacity of the pallet assembly, and enables the pallet assembly to meet the palletizing and transporting needs of heavy goods.

[0084] It should be noted that pallet assemblies can not only expand their horizontal dimensions to meet the palletizing and transporting needs of items of different sizes, but also expand their vertical dimensions to meet the palletizing and transporting needs of items of different weights. This further improves the versatility of pallet assemblies, reduces the number of pallet sizes, and lowers warehouse management costs.

[0085] In one embodiment, see Figure 3 and Figure 4 The first tray 10 has a first insertion groove 113 on one side of the first supporting surface 111.

[0086] Optionally, the first insertion slot 113 is a circular slot. Of course, in other embodiments, the first insertion slot 113 may also be of other shapes, and is not limited thereto.

[0087] Further, see Figure 2 , Figure 5 and Figure 6 The first tray 10 also includes a first support foot 12, which is located on the side of the first tray 10 away from the first support surface 111. The first support foot 12 is used to cooperate with the first insertion slot 113 of another first tray 10 adjacent to it.

[0088] Optionally, the first support leg 12 is a cylinder. Of course, in other embodiments, the first support leg 12 may also be other shapes, and is not limited thereto.

[0089] With the cooperation of the first support leg 12 and the first insertion slot 113, the splicing between two adjacent layers of the first pallet 10 can be realized, preventing the first pallet 10 from shifting and ensuring the stability of the pallet transport. In addition, the first support leg 12 is set on the side of the first pallet 11 away from the first support surface 111, so that the first support surface 111 is flat, thereby ensuring the stability of the pallet transport.

[0090] In one embodiment, within the same first pallet 10, the first insertion slot 113 and the first support leg 12 are positioned opposite each other. It is understood that the central axis of the first insertion slot 113 coincides with the central axis of the first support leg 12, thus allowing the load borne by the upper first pallet 10 to be directly transferred to the lower first pallet 10 through the first support leg 12, forming a stable load-bearing frame, which is beneficial for improving the load-bearing capacity and overall stability of the pallet assembly.

[0091] In one embodiment, see Figure 4 Multiple first insertion slots 113 are provided, and the multiple first insertion slots 113 are arranged in an array. In this embodiment, the first insertion slots 113 are arranged in a four-row, four-column array.

[0092] The first tray 11 has at least one edge with a plurality of first splicing grooves 112. These grooves are spaced apart along the extending direction of their respective edges and are staggered from the first insertion grooves 113 in their arrangement direction. Optionally, the first splicing grooves 112 and the peripheral first insertion grooves 113 are arranged alternately. This avoids interference between the first splicing grooves 112 and the first insertion grooves 113, while also ensuring the size of the first splicing grooves 112, which helps increase the connection area between the splicing protrusion 212 and the groove wall of the first splicing groove 112, thereby improving the splicing strength and firmness of the first tray 10 and the second tray 20.

[0093] In one embodiment, see Figure 11 and Figure 12 The system includes at least two second pallets 20, which can be stacked and spliced ​​with their corresponding first pallets 10. In use, the pallets with expanded support surfaces can be stacked, which increases the thickness of the pallet assembly, improves its load-bearing capacity, and enables the pallet assembly to meet the palletizing and transporting needs of heavy goods.

[0094] In one embodiment, see Figure 7 and Figure 8 The second support plate 21 has a second insertion groove 213 on one side of the second support surface 211.

[0095] Optionally, the second insertion slot 213 is a circular slot. Of course, in other embodiments, the second insertion slot 213 may also be of other shapes, and is not limited thereto.

[0096] See Figure 2 , Figure 9 and Figure 10 The second tray 20 also includes a second support foot 22, which is located on the side of the second tray 21 away from the second support surface 211. The second support foot 22 is used to cooperate with the second insertion slot 213 of the second tray 20 adjacent to it.

[0097] Optionally, the second support leg 22 is a cylinder. Of course, in other embodiments, the second support leg 22 may also be other shapes, and is not limited thereto.

[0098] With the cooperation of the second support foot 22 and the second insertion slot 213, the splicing between two adjacent layers of second pallets 20 can be realized, preventing the second pallets 20 from shifting and ensuring the stability of pallet transport. In addition, the second support foot 22 is located on the side of the second pallet 21 away from the second support surface 211, making the second support surface 211 flat, which helps to improve the stability of pallet transport.

[0099] In one embodiment, see Figure 7In the same two first trays 10, the second insertion slot 213 and the second support leg 22 are positioned opposite each other. It can be understood that the central axis of the second insertion slot 213 coincides with the central axis of the second support leg 22. This allows the load borne by the upper second tray 20 to be directly transferred to the lower second tray 20 through the second support leg 22, forming a stable load-bearing frame, which is beneficial to improving the load-bearing capacity and overall stability of the tray assembly.

[0100] In one embodiment, see Figure 8 Multiple second insertion slots 213 are provided, and the multiple second insertion slots 213 are spaced apart along the length direction of the second support plate 21. In this embodiment, see reference. Figure 7 and Figure 10 There are four second insertion slots 213, which are spaced apart along the length of the second support plate 21.

[0101] Multiple splicing protrusions 212 are provided, spaced apart along the length of the second support plate 21, and staggered from the second insertion slots 213 along the length of the second support plate 21. Optionally, the multiple splicing protrusions 212 and the multiple second insertion slots 213 are arranged alternately along the length of the second support plate 21. This arrangement avoids stress concentration, and when horizontal splicing and vertical stacking are performed simultaneously, the force transmission path is more uniform, which helps to improve overall rigidity and reliability.

[0102] In one embodiment, both the first pallet 10 and the second pallet 20 are made of EPP (Expanded Polypropylene). Because the pallet assembly is made of EPP, it not only achieves lightweight design for easy handling, but also effectively mitigates vibration and impact during transportation, thus protecting the goods. Furthermore, the durability of EPP material helps extend the service life of the pallet assembly.

[0103] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0104] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0105] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0106] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0107] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0108] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
