[0046] As mentioned above, the pallet legs of thermoplastic composite pallets are typically designed as a single unit, welded to the top and bottom panels of the pallet using hot-melt welding technology, or the pallet legs are two- or three-section snap-fit ​​assembly that attaches to the top and bottom panels of the pallet. Whether the pallet legs are one-piece or two- or three-section snap-fit ​​assembly, they are difficult to repair and replace after impact damage, resulting in low maintainability and interchangeability. Furthermore, snap-fit ​​pallet legs are inconvenient to install and remove, leading to low work efficiency, easy damage, and negatively impacting cost control.

[0047] To address the aforementioned issues, in this embodiment of the invention, the support component is detachably connected to the upper panel via a screw connection. This allows for easy replacement of the damaged support component when it is damaged, improving the pallet's maintainability and interchangeability, thereby reducing costs. The support component employs a design with staggered first and second grooves along its height, and the bottom of the first groove features a first connecting structure for connecting to the upper panel. This design saves materials while ensuring the overall strength of the support component, effectively resisting tensile and bending forces generated during use. It meets load-bearing requirements while allowing for repeated disassembly and reassembly without significant damage, extending the service life of the support component and reducing costs. Furthermore, when applied to a pallet, the support component is screwed to the upper panel, allowing users to quickly disassemble and assemble the pallet using power assembly tools (such as electric screwdrivers), improving work efficiency.

[0048] Furthermore, the ability of pallets to be quickly disassembled and assembled facilitates the disassembly of pallets during transport, allowing for the neat packaging of individual components and loading them onto the truck in a modular fashion. After unloading, they can be quickly reassembled for use, thus improving the utilization of transport space and reducing transportation costs.

[0049] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] Reference Figures 1 to 9This utility model embodiment provides a support component 10 for a pallet 100. The support component 10 is screwed onto the underside of the upper panel 20 of the pallet 100 to support the upper panel 20. Each pallet 100 can be supported by multiple support components 10. The support components 10 can lift the upper panel 20 of the pallet 100 off the ground to a certain height, providing corresponding operating space for the forklift forks when transporting the pallet 100 by forklift.

[0051] In a specific implementation, the support assembly 10 includes a support body 11 and a plurality of first nuts 12. The support body 11 has a top plate 111 and a bottom plate 112 disposed opposite each other in its height direction. The top plate 111 faces the lower surface 22 of the upper panel 20. The bottom plate 112 is provided with a plurality of first grooves 113, the bottom 1131 of which is coplanar with the top plate 111. The top plate 111 is provided with a plurality of second grooves 114, which are staggered in the height direction. A plurality of first connecting structures are respectively embedded in the bottom 1131 of the corresponding first groove 113. The first connecting structures are used to connect the upper panel.

[0052] As shown above, the support component 10 is detachably connected to the upper panel 20 via a screw connection. This allows for easy replacement of the damaged support component 10 when it is damaged, improving the maintainability and interchangeability of the pallet 100. The support component 10 employs a design with staggered first grooves 113 and second grooves 114 along its height. The bottom 1131 of the first groove 113 features multiple first connecting structures for connecting to the upper panel 20. This design saves materials while increasing the overall strength of the support component 10, effectively resisting tensile and bending forces generated during use. It meets load-bearing requirements while allowing for repeated disassembly and reassembly without significant damage, extending the service life of the support component 10 and reducing costs. Since the support component 10 is screwed to the upper panel 20, it can be quickly replaced when damaged, further improving its maintainability and interchangeability and reducing costs.

[0053] In practice, the first connection structure can have various structural styles, as illustrated below.

[0054] In some embodiments, see Figure 6 , Figure 7 as well as Figure 9The first connection structure includes a first mounting hole 1132. The first mounting hole 1132 is used to cooperate with a first fastener 71 to connect the upper panel 20. At this time, at least a portion of the bottom 1131 of the plurality of first grooves 113 are provided with the first mounting hole 1132, and the bottom 1131 of the bottom portion of the first grooves 113 are connected to the upper panel 20 through the first fastener 71 cooperating with the first mounting hole 1132.

[0055] The first fastener 71 can be a bolt, and the first mounting hole 1132 is a bolt hole adapted to the bolt. Figure 6 , Figure 7 and Figure 9 The diagram illustrates a support component 10 comprising five first grooves 113, with a first mounting hole 1132 provided on the bottom 1131 of four of the first grooves 113. Four first fasteners 71 are used as an example. It is understood that in practice, the number of first fasteners 71 can also be three, five, or other numbers.

[0056] The tray 100 may further include a lower panel 40. The bottom 1141 of the second groove 114 is coplanar with the base plate 112. The support assembly 10 further includes a plurality of second connecting structures disposed at the bottom 1141 of the corresponding second groove 114. The second connecting structures are used to connect the lower panel 40 of the tray 100. The second connecting structure includes a second mounting hole 1142, which is used to cooperate with a second fastener to connect the lower panel 40.

[0057] At least a portion of the second grooves 114 have a second mounting hole 1142 at their bottom 1141. In this case, the bottom 1141 of at least a portion of the second grooves 114 are connected to the lower panel 40 by a second fastener 72 engaging with the second mounting hole 1142.

[0058] The second fastener 72 can be a bolt, and the second mounting hole 1142 is a bolt hole adapted to the bolt. Figure 6 , Figure 7 and Figure 9 The support component 10 includes the bottom 1141 of four second grooves 114. Each second groove 114 has a second mounting hole 1142 at its bottom. The example uses four second fasteners 72. In practice, the number of second fasteners 72 can be three, five, or other numbers.

[0059] In other embodiments, see Figures 1 to 5 , Figure 8 The first connecting structure includes a first nut 12, which is embedded in the bottom 1131 of the corresponding first groove 113.

[0060] It should be noted that, in order to better demonstrate the first nut 12 embedded in the bottom 1131 of the first groove 113, Figure 4 The diagram is presented using perspective.

[0061] Furthermore, when applied to the pallet 100, the support component 10 is screwed to the upper panel 20, allowing users to quickly disassemble and assemble the pallet 100 using power assembly tools (such as electric screwdrivers), thus improving work efficiency. The pallet 100 provided in this application facilitates later maintenance and component replacement, is energy-saving and environmentally friendly, and possesses good sustainability advantages.

[0062] Furthermore, because the pallet 100 can be quickly disassembled and assembled, it facilitates the disassembly of the pallet during transportation, allowing the individual components to be neatly packaged and stacked like building blocks for loading and transport. After unloading, it can be quickly reassembled and used, thus improving the full utilization of transportation space and reducing transportation costs.

[0063] In some embodiments, the projections of the first groove 113 and the second groove 114 on the top plate 111 are arranged in a cross pattern. Thus, on the top plate 111, the bottom 1131 of the first guide groove 113 and the opening of the second groove 114 are arranged in a cross pattern. On the bottom plate 112, the opening of the first groove 113 and the bottom 1141 of the second groove 114 are arranged in a cross pattern. This cross arrangement of the groove bottoms and openings achieves a partially hollowed-out design for the support body 11, saving costs and achieving a lightweight support assembly 10 while ensuring that the top plate 111 and the bottom plate 112 have good support strength and load-bearing capacity.

[0064] In some embodiments, the interior of the support body 11 is provided with a plurality of cross-arranged reinforcing ribs 115.

[0065] Furthermore, the reinforcing rib 115 is connected to at least the top plate 111 and the bottom plate 112. By supporting the top plate 111 and the bottom plate 112 with the reinforcing rib 115, the load-bearing capacity of the support assembly 10 can be improved.

[0066] Furthermore, the support body 11 also includes sidewalls 117 connected to the top 111 and the bottom 112. The reinforcing ribs 115 are connected to the top plate 111 and the bottom plate 112, and also to at least a portion of the sidewalls 117. Thus, when the support assembly 10 is under stress, the reinforcing ribs 115 pull the sidewalls 117 toward the interior of the support body 11, reducing the probability of the support body 11 deforming under stress and improving the load-bearing capacity of the support body 11.

[0067] In some non-limiting embodiments, the reinforcing rib 115 may include a reinforcing rib 115 extending along a first direction and a reinforcing rib 115 extending along a second direction. It should be noted that, in order to better illustrate the reinforcing rib 115 disposed inside the support body 11, Figure 2 The main support structure 11 was cut open.

[0068] In some embodiments, the first direction and the second direction are perpendicular. For example, the support body 11 is generally rectangular, the first direction is the length direction of the supporting font 10, and the second direction is the width direction of the support body 11.

[0069] Both the number of reinforcing ribs 115 extending along the first direction and the number of reinforcing ribs 115 extending along the first direction can be multiple. For example, the figure illustrates three reinforcing ribs 115 extending along the first direction and three reinforcing ribs 115 extending along the second direction, with the six reinforcing ribs 115 intersecting to form a nine-square grid structure.

[0070] In some embodiments, the thickness of the reinforcing rib 115 in the direction perpendicular to the height direction is greater than or equal to 2 mm. This allows the reinforcing rib 115 to have better strength, thereby improving the supporting effect of the support body 11 and enhancing its resistance to external forces.

[0071] In some embodiments, along the height direction, the thickness of the bottom 1131 of the first groove 113 is greater than the height of the first nut 12. This helps ensure that the first nut 12 can be fully embedded inside the bottom 1131 of the first groove 113. During the use of the tray 100, especially when the support assembly 10 is repeatedly disassembled and installed, the probability of the first nut 12 falling out of the first groove 113 can be reduced, thereby extending the lifespan of the support assembly 10.

[0072] In some embodiments, the distance between the end of the first nut 12 closest to the top plate 111 and the top plate 111 is greater than or equal to 1.5 mm.

[0073] In some embodiments, a first annular groove 121 is provided on one of the groove bottoms 1131 of the first nut 12 and the first groove 113, and a first annular protrusion is provided on the other of the groove bottoms 1131 of the first nut 12 and the first groove 113, the first annular protrusion being adapted to the first annular groove 121. The cooperation between the first annular protrusion and the first annular groove 121 improves the fusion between the first nut 12 and the top plate 111, increasing the firmness of their connection.

[0074] The accompanying drawings provided in this application illustrate an example where a first annular groove 121 is provided on the first nut 12, and a first annular protrusion is provided on the bottom 1131 of the first groove 113. It should be noted that when the support assembly 10 is integrally molded by injection molding, since the first nut 12 is provided with the first annular groove 121, during the injection molding process, the injection molding material (such as PP resin) will enter the first annular groove 121. Thus, after the injection molding is completed, a first annular protrusion that matches it will be formed in the first annular groove 121.

[0075] In some non-limiting embodiments, the first annular groove 121 is disposed at the middle position of the first nut 12.

[0076] In some non-limiting embodiments, the depth of the first annular groove 121 is not less than 0.5 mm.

[0077] In some non-limiting embodiments, the width of the first annular groove 121 in the extending direction of the first nut 12 is greater than or equal to 2 mm.

[0078] In some embodiments, at least one end of the first nut 12 is provided with a first concave-convex structure 122 along the axial direction (i.e., the extension direction) of the first nut 12. The first concave-convex structure 122 can further improve the gripping force between the first nut 12 and the top plate 111. In particular, when the support assembly 10 is integrally molded by injection molding, the injection molding material (such as PP resin) can be more fully fused with the first nut 12, further increasing the connection between the first nut 12 and the bottom 1131 of the first groove 113, and preventing the first nut 12 from falling off the top plate 111.

[0079] In some embodiments, the first nut 12 has an internal thread. The internal thread of the first nut 12 can be an M8 thread, an M6 thread, an M10 thread, etc. The inner diameter of the internal thread can be adapted to the screw used, and examples will not be given here.

[0080] In some embodiments, see continue to see Figures 1 to 5 , Figure 8 The bottom 1141 of the second groove 114 is coplanar with the base plate 112. The support assembly 10 also includes a plurality of second connecting structures, which are respectively disposed on the bottom 1141 of the corresponding second groove 114. The second connecting structure includes a second nut 13, which is embedded in the bottom 1141 of the corresponding second groove 114.

[0081] In some embodiments, along the height direction, the thickness of the bottom 1141 of the second groove 114 is greater than the height of the second nut 13. This helps ensure that the second nut 13 can be fully embedded inside the bottom 1141 of the second groove 114. During the use of the tray 100, especially when the support assembly 10 is repeatedly disassembled and installed, the probability of the second nut 13 falling out of the second groove 114 is reduced, thereby extending the lifespan of the support assembly 10.

[0082] In some embodiments, the distance between the end of the second nut 13 closest to the bottom plate 112 and the top plate 111 is greater than or equal to 1.5 mm.

[0083] In some embodiments, a second annular groove 131 is provided on one of the groove bottoms 1141 of the second nut 13 and the second groove 114, and a second annular protrusion is provided on the other of the groove bottoms 1141 of the second nut 13 and the second groove 114, the second annular protrusion being adapted to the second annular groove 131.

[0084] The accompanying drawings provided in this application illustrate an example where a second annular groove 131 is provided on the second nut 13, and a second annular protrusion is provided on the bottom 1141 of the second groove 114. It should be noted that when the support assembly 10 is integrally molded by injection molding, because the second nut 13 has a second annular groove 131, during the injection molding process, the injection molding material (such as PP resin) will enter the second annular groove 131. Thus, after injection molding is completed, a matching second annular protrusion will be formed within the second annular groove 131.

[0085] In some non-limiting embodiments, the second annular groove 131 is disposed at the middle position of the second nut 13.

[0086] In some non-limiting embodiments, the depth of the second annular groove 131 is not less than 0.5 mm.

[0087] In some non-limiting embodiments, the width of the second annular groove 131 in the extending direction of the second nut 13 is greater than or equal to 2 mm.

[0088] In some embodiments, at least one end of the second nut 13 is provided with a second concave-convex structure 132 along the axial direction (i.e., the extension direction) of the second nut 13. The second concave-convex structure 132 can further improve the gripping force between the second nut 13 and the base plate 112. In particular, when the support assembly 10 is integrally molded by injection molding, the injection molding material (such as PP resin) can be more fully fused with the second nut 13, further increasing the firmness of the connection between the second nut 13 and the bottom 1141 of the second groove 114, and preventing the second nut 13 from falling off the base plate 112.

[0089] In some embodiments, the second nut 13 has an internal thread. The internal thread of the second nut 13 can be an M8 thread, an M6 thread, an M10 thread, etc. The inner diameter of the internal thread can be adapted to the screw used, and examples will not be given here.

[0090] In some embodiments, the number of first nuts 12 is greater than or equal to the number of second nuts 13. In the accompanying drawings, the top plate 111 is provided with four second grooves 114, and the bottom plate 112 is provided with five first grooves 113. Each first groove 113 has a first nut 12 embedded in its groove bottom 1131, and each second groove 114 has a second nut 13 embedded in its groove bottom 1141, as illustrated in this example.

[0091] It should be noted that the number of the first nut 12 and the second nut 13 is not limited to this, and can be other numbers in practice. The bottom 1131 of the first groove 113 can also be embedded with two or more first nuts 12, and the bottom 1141 of the second groove 114 can also be embedded with two or more second nuts 13, depending on the needs of the actual application scenario.

[0092] In some non-limiting embodiments, a plurality of first nuts 12 are arranged symmetrically on the top plate 111. For example, the plurality of first nuts 12 are arranged centrally symmetrically, or symmetrically arranged relative to the center line of the top plate 111. This facilitates blind installation of the support assembly 10 and improves installation efficiency.

[0093] In some non-limiting embodiments, a plurality of second nuts 13 are arranged symmetrically on the base plate 112. For example, the plurality of second nuts 13 are arranged centrally symmetrically, or symmetrically arranged relative to the center line of the base plate 112. This facilitates blind installation of the support assembly 10 and improves installation efficiency.

[0094] In some embodiments, skirts 116 extend along the planar direction of the top plate 111 and / or the bottom plate 112, respectively. The skirts 116 on the top plate 111 ensure the contact area between the support assembly 10 and the upper panel 20, thereby ensuring support force. The skirts 116 on the bottom plate 112 ensure the contact area between the support assembly 10 and the lower panel 40 or the ground, thereby ensuring support force.

[0095] In some embodiments, the support assembly 10 further includes a guide structure disposed between the top plate 111 and the bottom plate 112. The guide structure is used to guide the forward direction of the forklift's forks, reducing the damage to the support assembly 10 caused by forklift impact.

[0096] In some embodiments, the support body 11 further includes a sidewall 117 for connecting the top plate 111 and the bottom plate 112, and an elastic buffer is provided on the sidewall 117. The elastic buffer can be elastic rubber or the like. The elastic buffer can be attached to the sidewall 117 with adhesive. The buffer material can be rubber, such as styrene-butadiene rubber, nitrile rubber, ethylene propylene rubber, butadiene rubber, silicone rubber, or isoprene rubber. The selected adhesive is any one of epoxy resin, acrylic resin, polyurethane resin, etc. The elastic buffer can absorb the impact force of the fork teeth on the support assembly 10, reducing the probability of damage to the support assembly 10.

[0097] This utility model embodiment also provides a tray 100, see [link / reference] Figures 1 to 9 The tray 100 includes: a top panel 20 and any of the aforementioned support components 10. The specific structure of the support component 10 can be found in the descriptions of the above embodiments, and will not be repeated here.

[0098] In some embodiments, the upper panel 20 is a composite honeycomb panel. For example, the composite honeycomb panel may include two panels made of continuous fiber reinforced thermoplastic composite (CFRTP) and a honeycomb core located between the two panels. The honeycomb core may be made of polypropylene (PP). CFRTP, as a new type of lightweight composite material, refers to a lightweight, high-strength, high-rigidity, high-toughness, environmentally friendly, and recyclable new thermoplastic composite material formed by resin melt impregnation, extrusion, and other processes using thermoplastic resin as the matrix and continuous fibers as the reinforcing material. Using CFRTP to make the upper panel 20 can reduce the weight of the upper panel 20, thereby helping to achieve the requirements of lightweighting and environmental protection of the pallet 100.

[0099] In a specific implementation, the tray 100 further includes a plurality of first reinforcing pads 30. The plurality of first reinforcing pads 30 are located above the upper panel 20 and correspond one-to-one with the positions of the plurality of support components 10. Each first reinforcing pad 30 is provided with a plurality of first connecting holes, which correspond to the positions of a plurality of first nuts 12 in the support component 10 corresponding to that first reinforcing pad 30. By having the first reinforcing pads 30 contact the upper panel 20, the fastening pressure of the connection can be distributed to the upper panel 20, reducing the probability of cracking of the upper panel 20 due to stress concentration and improving the service life of the upper panel 20. Furthermore, distributing the fastening force through the first reinforcing pads 30 helps to achieve a greater fastening force for locking the support components 10 and the upper panel 20, thereby increasing the locking firmness and increasing the load-bearing capacity of the tray 100.

[0100] In some embodiments, the upper panel 20 is provided with a plurality of first mating holes 24. The plurality of first connecting holes on the first reinforcing pad 30 each have a corresponding first mating hole 24.

[0101] In some non-limiting embodiments, see Figure 8 When assembling the top plate 20 and the support assembly 10, the first screw 61 passes through the first connecting hole and the first mating hole 24 in sequence and is screwed into the first nut 12.

[0102] After the first screw 61 is connected to the first nut 12, part of the first screw 61 is located in the first groove 113 and does not protrude from the first groove 113, so as to avoid interference of the first screw 61 with the assembly of the lower panel 40 and to avoid affecting the placement stability of the support assembly 10.

[0103] In other non-limiting embodiments, see [link to other embodiments]. Figure 9 The upper panel 20 is connected to the bottom 1131 of the first groove 113 by a first fastener 71. When the upper panel 20 and the support assembly 10 are assembled, the first fastener 71 (e.g., bolt or screw) is passed through the first connecting hole and the first mating hole 24 in sequence and screwed into the first mounting hole 1132.

[0104] After the first fastener 71 is screwed into the first mounting hole 1132, part of the first fastener 71 is located in the first groove 113 and does not protrude from the first groove 113, so as to avoid interference of the first fastener 71 with the assembly of the lower panel 40 and to avoid affecting the placement stability of the support component 10.

[0105] The first connecting hole is a countersunk hole. In this way, the top of the first screw 61 or the first fastener 71 can be accommodated in the first connecting hole, so that the first screw 61 or the first fastener 71 does not protrude from the upper surface of the first reinforcing pad 30, thereby making the upper panel 20 of the pallet 100 have better flatness, so as to avoid affecting the loaded goods.

[0106] In some embodiments, the first reinforcing pad 30 includes a metal layer and an anti-corrosion layer covering the metal layer. By covering the metal layer with an anti-corrosion layer, the corrosion resistance of the first reinforcing pad 30 can be improved, so as to better adapt to the outdoor environment of wind and sun, and improve the service life of the first reinforcing pad 30.

[0107] The metal layer can be a steel plate or a plate made of other metal materials.

[0108] The anti-corrosion layer can be formed on the surface of a metal layer through surface treatments such as pre-galvanizing or electrophoresis. Alternatively, the anti-corrosion layer can be made of CFRTP fiberglass board.

[0109] In some embodiments, the upper surface 21 of the upper panel 20 is provided with a plurality of first receiving grooves 23, and the plurality of first receiving grooves 23 are respectively used to accommodate the corresponding first reinforcing pads 30.

[0110] In some embodiments, after the first reinforcing pad 30 is placed in the first receiving groove 23, the upper surface of the first reinforcing pad 30 is flush with the upper surface 21 of the upper panel 20. This improves the overall integrity of the support assembly 10.

[0111] In some non-limiting embodiments, the forming process of the first receiving groove 23 varies depending on the material of the upper panel 20. For example, if the upper panel 20 is made of a composite honeycomb material, the first receiving groove 23 can be formed by hot molding. Alternatively, the first receiving groove 23 may be formed during the fabrication process of the upper panel 20.

[0112] In a specific implementation, the tray 100 further includes a lower panel 40 located below the support assembly 10, the lower panel 40 being screwed to the support assembly 10.

[0113] The bottom plate 40 can have various structural styles, such as Figure 8 and Figure 9 As shown, the lower panel 40 is elongated. There can be multiple lower panels 40, such as the three shown in the figure. In this case, the bottom of the tray 100 has a U-shape. The structure of the lower panel 40 can also be the same as that of the upper panel 20.

[0114] In practice, the lower panel 40 is a composite honeycomb panel.

[0115] In some embodiments, the tray 100 further includes a plurality of second reinforcing pads 50 located below the lower panel 40 and corresponding one-to-one with the positions of the plurality of support components 10. Each second reinforcing pad 50 is provided with a plurality of second connecting holes, and the plurality of second connecting holes correspond to the positions of a plurality of second nuts 13 in the support component 10 corresponding to the second reinforcing pad 50.

[0116] By having the second reinforcing pad 50 contact the lower panel 40, the fastening pressure of the connection can be distributed to the lower panel 40, avoiding stress concentration and the probability of cracking of the lower panel 40, thus increasing the service life of the lower panel 40. In addition, the distribution of fastening force by the second reinforcing pad 50 helps to achieve a greater fastening force to lock the support assembly 10 and the lower panel 40, thereby increasing the locking firmness and increasing the load-bearing capacity of the tray 100.

[0117] In some embodiments, the lower panel 40 is provided with a plurality of second mating holes 41. The plurality of second connecting holes on the second reinforcing pad 50 each have a corresponding second mating hole 41.

[0118] In some non-limiting embodiments, see Figure 8 When assembling the bottom plate 40, the second screw 62 is passed through the second connecting hole and the second mating hole 41 in sequence, and screwed into the second nut 13.

[0119] After the second screw 62 is connected to the second nut 13, part of the second screw 62 is located in the second groove 114 and does not protrude from the second groove 114, so as to avoid affecting the placement stability of the support assembly 10.

[0120] In some other non-limiting embodiments, the lower panel 40 is connected to the bottom 1141 of the second groove 114 by a second fastener 71. During assembly of the lower panel 40, the second fastener 72 (e.g., a bolt or screw) passes sequentially through the second connecting hole and the second mating hole 41, and is connected to the second mounting hole 1142.

[0121] After the second fastener 72 (e.g., bolt or screw) is connected to the second mounting hole 1142, part of the second fastener 72 (e.g., bolt or screw) is located in the second groove 114 and does not protrude from the second groove 114, so as to avoid affecting the placement stability of the support component 10.

[0122] In some non-limiting embodiments, the second connecting hole is a countersunk hole. In this way, the top of the second screw 62 or the second fastener 72 can be received in the second connecting hole, so that the second screw 62 or the second fastener 72 does not protrude from the second reinforcing pad 50, thereby giving the lower panel 40 of the tray 100 better flatness and ensuring the stability of the tray 100 when placed.

[0123] In some embodiments, the second reinforcing pad 50 includes a metal layer and an anti-corrosion layer covering the metal layer. By forming the second reinforcing pad 50 by covering the metal layer with an anti-corrosion layer, the corrosion resistance of the second reinforcing pad 50 can be improved, allowing it to better adapt to outdoor wind and sun exposure and extending its service life. The structure of the metal layer and the anti-corrosion layer in the second reinforcing pad 50 is the same as that in the first reinforcing pad 30. For a detailed description of the metal layer and the anti-corrosion layer, please refer to the description in the above embodiments; further details will not be repeated here.

[0124] In a specific implementation, the lower surface of the lower panel 40 is provided with a plurality of second receiving grooves, each of which is used to accommodate a corresponding second reinforcing pad 50. This improves the overall integrity of the support assembly 10.

[0125] In some non-limiting embodiments, the forming process of the second receiving groove varies depending on the material of the lower panel 40. For example, if the lower panel 40 is made of a composite honeycomb material, the second receiving groove can be formed by hot molding. Alternatively, the second receiving groove can be formed during the fabrication process of the lower panel 40.

[0126] After the second reinforcing pad 50 is placed in the second receiving groove, the lower surface of the second reinforcing pad 50 is flush with the lower surface of the lower panel 40.

[0127] In some embodiments, the lower surface of the lower panel 40 may be provided with an anti-slip structure. The anti-slip structure may be an anti-slip texture formed on the lower panel 40, or an anti-slip pad connected to the lower surface of the lower panel 40.

[0128] Furthermore, the support component 10 in the pallet 100 is connected to the upper panel 20 by screwing. Compared with the integrated pallet in the prior art, the hot melt welding process can be eliminated. In this way, the equipment and manufacturing costs can be reduced, while the requirements of sturdiness and load-bearing capacity can be met and production efficiency can be improved.
