In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0024] like Figure 1-3As shown, an EPP (Enhanced Power Supply) modular pallet includes a bottom support frame 1, a top plate 2, and an assembly located between the bottom support frame 1 and the top plate 2. The bottom support frame 1 includes several horizontally arranged first support plates 3 and several vertically arranged second support plates 4. The bottom support frame 1 is composed of horizontally and vertically arranged support plates. This design provides a stable support structure, can evenly distribute weight, and ensures that the pallet remains stable when carrying goods, and is not easily deformed or tilted. The assembly includes a first assembly mounted on the bottom support frame 1 and a second assembly located below the top plate 2. The first and second assemblies are snapped together. The first and second assemblies are connected by a snap-fit ​​method, which makes the assembly process simple and quick.

[0025] The first assembly includes a square base post 5, with a connecting plate 6 fixedly connected to its lower part. The connecting plate 6 is integrally formed with the lower part of the square base post 5 and is bolted to the bottom support frame 1. This connection method is not only strong and reliable but also facilitates disassembly and reinstallation. The bolted connection can be adjusted as needed to adapt to different installation environments and requirements. The bottom support frame 1 has a grid-like structure, with the square base post 5 installed at the intersection of the first support plate 3 and the second support plate 4. This design provides strong support and stability. The grid-like structure ensures that the pallet bears weight evenly, reducing deformation or damage caused by excessive local stress. The installation of the square base post 5 at the intersection of the first support plate 3 and the second support plate 4 further enhances the overall structural stability of the pallet. As a node of the support structure, the intersection can withstand greater forces, making the pallet more robust and durable.

[0026] The second assembly includes a square flange 7, with a mounting groove 8 on its inner side. The dimensions of the mounting groove 8 match the dimensions of the square base post 5. The square base post 5 of the first assembly and the square flange 7 of the second assembly are engaged via the mounting groove 8. This design makes the assembly process very simple. No complicated tools or professional skills are required; simply align the square base post 5 with the mounting groove 8 and insert it, greatly improving work efficiency. Example 2

[0027] like Figure 4-6As shown, this embodiment has the same parts as Embodiment 1, the difference being that: in this embodiment, the bottom support frame 1 has a H-shaped structure, the first assembly includes a first connecting block 9, the first connecting block 9 has a cavity 10 inside, the cavity 10 has two symmetrically arranged assembly protrusions 11, a first cavity portion 12 is formed between the two assembly protrusions 11, and a second cavity portion 13 is formed on the sides of the two assembly protrusions 11. The second assembly includes a second connecting block 14, the bottom of the second connecting block 14 has two symmetrically arranged assembly grooves 15, a first protrusion 16 is formed between the two assembly grooves 15, and a second protrusion 17 is formed on the sides of the two assembly grooves 15. By matching the assembly protrusions 11 with the assembly grooves 15, precise docking between the two assemblies can be ensured. The symmetrically arranged assembly protrusions 11 and assembly grooves 15 can ensure that the assembly can be evenly stressed when subjected to external forces, reducing stress concentration, thereby improving the stability and reliability of the entire structure. Meanwhile, the tight fit between the assembly protrusion 11 and the assembly groove 15 can reduce loosening and shaking, ensuring the safety of goods during transportation or storage.

[0028] The design of the first recessed portion 12 and the first protrusion 16, the second recessed portion 13 and the second protrusion 17 not only increases the contact area between the assemblies and improves the stability of the connection, but also allows for a certain degree of fault tolerance, making the assembly process easier. If an assembly is damaged or needs to be replaced, it can be easily removed from the entire tray for replacement without replacing the entire tray, reducing maintenance costs. Example 3

[0029] This embodiment is a further improvement based on Embodiment 2. In this embodiment, the bottom of the first concave cavity 12 is provided with a T-shaped strip-shaped locking block 18, and the bottom of the first protrusion 16 is provided with a locking groove 19. The bottom sides of the locking groove 19 are provided with a first limiting part 20 and a second limiting part 21, and the distance between the first limiting part 20 and the second limiting part 21 gradually decreases downward. The tight fit between the T-shaped strip-shaped locking block 18 and the locking groove 19 can effectively prevent the two assemblies from shifting in the vertical direction, ensuring that the connection between them is stable and reliable. The design of the distance between the first limiting part 20 and the second limiting part 21 gradually decreasing downward forms a funnel-like structure, which further enhances the locking effect between the locking block and the locking groove 19.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
