The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0030] First embodiment:

[0031] See also Figures 1 to 4 ,in Figure 1 This is a structural diagram of the assembled logistics pallet of the first embodiment. Figure 2 This is a schematic diagram of the partially disassembled structure of the assembled logistics pallet of the first embodiment. Figure 3 This is a schematic diagram of the structure of the extended side plate in the first embodiment. Figure 4 2 is a schematic structural diagram of the extended end plate in the first embodiment.

[0032] The present invention provides a modular logistics pallet comprising a base support plate 101, multiple rows of first legs 102, and a plurality of modular expansion units, each of which includes two expansion side panels 103 and two expansion end panels 104. This solution addresses the problems of existing logistics pallets, such as the inability of fixed-size pallets to accommodate cargo of varying sizes, and the lack of reliable connection and susceptibility to displacement when multiple independent pallets are used in combination. It is understood that the solution can be applied to the structure of modular logistics pallets.

[0033] According to this specific embodiment, the bottom plate of the base support plate 101 is evenly spaced and provided with multiple rows of the first legs 102. The base support plate 101 is made of lightweight and high-strength composite materials. The core layer of the base support plate is a honeycomb aluminum structure or a foamed polymer matrix. The surface layer of the base support plate is a glass fiber reinforced epoxy resin layer or a carbon fiber reinforced thermoplastic plastic layer. The core layer composed of the honeycomb aluminum structure or the foamed polymer matrix can provide high specific strength (strength / weight ratio) and reduce the weight of the pallet (reduced by more than 30% compared with traditional wooden pallets). The surface layer composed of the glass fiber reinforced epoxy resin layer or the carbon fiber reinforced thermoplastic plastic layer can prevent the core layer from being compressed and shrinking, and at the same time enhance the moisture resistance and corrosion resistance. Multiple said assembled expansion The units are arranged on the outside of the base support plate 101 in increasing order. Specifically, the innermost assembly expansion unit is installed on the outside of the base support plate 101, and the next layer of assembly expansion units is installed on the outside of the innermost assembly expansion unit, and the whole assembly of the assembled material tray is completed in increasing order. The left and right sides of the base support plate 101 are penetrated by a first sliding groove 105, and each of the two sides of the expansion side plate 103 is respectively provided with a sliding plate 106 and a second sliding groove 107. The sliding plate 106 is inserted into the corresponding first sliding groove 105 or the corresponding second sliding groove 107. Both ends of each expansion side plate 103 are provided with a mounting protrusion 108. The front and rear ends of the supporting plate 101 are both provided with a first tenon 109, and both sides of each of the extended end plates 104 are respectively provided with a first tenon 110 and a second tenon 111, and the first tenon 110 is snapped into the corresponding first tenon 109 or the corresponding second tenon 111. A third tenon 112 is provided on each of the mounting protrusions 108, and both ends of each of the extended end plates 104 are provided with a second tenon 113, and the second tenon 113 is adapted to the third tenon 112. When it is necessary to transport goods of different sizes, the extended side plate 103 of the innermost assembled extension unit can be moved by setting the sliding plate 106 and the first sliding groove 105 according to actual needs. The mortise and tenon joints are installed on both sides of the base supporting plate 101. By setting the first tenon 110 and the first tenon groove 109, and the second tenon 113 and the third tenon groove 112, the extended end plate 104 of the innermost assembly extension unit is installed on both ends of the base supporting plate 101 by the mortise and tenon joints, completing the assembly of the innermost assembly extension unit. Then, by setting the sliding plate 106 and the second sliding groove, the extended side plate 103 of the next layer of assembly extension unit is installed on both sides of the innermost assembly extension unit by the mortise and tenon joints. By setting the first tenon 110 and the second tenon groove 111, and the second tenon 113 and the third tenon groove 112,The expansion end plates 104 of the next layer of assembly expansion units are installed on both ends of the assembly expansion units located in the innermost layer by mortise and tenon joints.

The third tenon 119 is inserted into the corresponding first mortise 116, the second mortise 117 or the third mortise 118. Through the setting of the first mortise 116, the second mortise 117, the third mortise 118 and the third tenon 119, the connection result of the auxiliary leg 115 is more stable.

[0037] In addition, each of the first legs 102, each of the second legs 114 and each of the auxiliary legs 115 is provided with an anti-slip pad 120 at the bottom. The provision of the anti-slip pad 120 makes the placement of the entire assembled logistics pallet more stable. The anti-slip pad 120 is made of any one of modified rubber, polyurethane elastomer and thermoplastic elastomer. When the anti-slip pad 120 is made of polyurethane elastomer, the bottom of the anti-slip pad 120 is designed as a diamond grid pattern with a depth of 1.5 mm, which can effectively divert liquid (prevent water accumulation and slipping). When the anti-slip pad 120 is made of modified rubber, a carbon black reinforcement agent is added to the modified rubber to improve the cutting resistance when in contact with the metal fork of the forklift.

[0038] When using an assembled logistics pallet of the present embodiment, the innermost assembly expansion unit is installed on the outside of the base support plate 101, and the next layer of assembly expansion units is installed on the outside of the innermost assembly expansion unit, and the assembly is completed in sequence. Specifically, when it is necessary to transport goods of different sizes, the extended side panels 103 of the innermost assembly expansion unit can be installed on both sides of the base support plate 101 by setting the sliding plate 106 and the first sliding groove 105 according to actual needs, and the extended end panels 104 of the innermost assembly expansion unit can be mortised by setting the first tenon 110 and the first tenon groove 109, and the second tenon 113 and the third tenon groove 112.
