[0054] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0055] In the description of the present invention, it should be understood that the orientation or positional relationship involved, such as up, down, etc., indicates the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0056] In the description of the present invention, "plural" means more than two. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features, and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0057] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "install", "connect", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0058] Refer to Figure 1 As shown, a pallet 1000 according to an embodiment of the present invention includes a pallet 200 for carrying goods, and the pallet 200 is formed by combining a plurality of support units 100. Among them, the pallet 1000 of the present embodiment realizes load bearing through the support unit 100, and has strong load-bearing capacity and can be circulated and used in multiple links of logistics transportation.

[0059] Refer to Figure 2 and Figure 3 As shown, a support unit 100 according to an embodiment of the present invention can be used on panel structures such as pallets and boxes to bear loads. The support unit 100 of the present embodiment includes a first plate 110 and a second plate 120 arranged at intervals. The first plate 110 and the second plate 120 can be made of metal materials, such as sheet metal parts, etc. The first plate 110 and the second plate 120 are processed by sheet metal parts, making the processing procedure of the support unit 100 simpler, and the manufactured support unit 100 has the characteristics of large structural strength and light weight. It can be understood that the first plate 110 and the second plate 120 can also be made of other metal sheet materials. The first plate 110 and the second plate 120 being made of metal is convenient for recycling, environmentally friendly and resource-saving.

[0060] It can be understood that both the first plate 110 and the second plate 120 are made of galvanized sheet or electrolytic sheet, because galvanized sheet and electrolytic sheet have many characteristics such as high strength, high ductility, corrosion resistance, radiation resistance, high-efficiency ultraviolet reflection, easy processing, light weight, recyclability, pest-free and low-carbon environmental protection.

[0061] Refer to Figure 1 As shown, for example, when the support unit 100 is used for pallet manufacturing, the support unit 100 is made into a pallet using galvanized sheet or electrolytic sheet, which fully meets the use requirements of the pallet, and the waste generated after disassembling the pallet made of galvanized sheet or electrolytic sheet is extremely small, and the recovery rate of the pallet made of the removed galvanized sheet or electrolytic sheet reaches more than 80%, meeting the requirements of environmental protection efficiency.

[0062] Continue to refer to Figure 2 andFigure 3 As shown, it can be understood that multiple first annular walls 111 are respectively arranged at intervals along the length direction and the width direction of the lower end surface of the first plate 110. The multiple first annular walls 111 extend towards the second plate 120. The first annular wall 111 is a tubular structure that is hollow and penetrates up and down. Multiple second annular walls 121 are arranged at intervals along the length direction and the width direction of the upper end surface of the second plate 120. The multiple second annular walls 121 extend towards the first plate 110. The second annular wall 121 is a tubular structure that is hollow and penetrates up and down. It should be noted that the lower end surface and the upper end surface mentioned here are only for this specific embodiment and cannot be limited to their absolute positions, but should be understood as their relative positions. For example, the lower end surface of the first plate 110 is one end surface of the first plate 110 facing the second plate 120, and the upper end surface of the second plate 120 is one end surface of the second plate 120 facing the first plate 110.

[0063] The multiple second annular walls 121 and the multiple first annular walls 111 are arranged in one-to-one correspondence. The second annular wall 121 is sleeved on the outer side of the first annular wall 111. The second annular wall 121 and the first annular wall 111 can be set to be tightly fitted and connected, so that the first annular wall 111 and the second annular wall 121 are bonded to form a stable support structure 130. The support structure 130 is used to support the first plate 110 and the second plate 120. It should be noted that the tightly fitted connection can be understood as a connection method in which there is no relative movement between the first annular wall 111 and the second annular wall 121. The first annular wall 111 and the second annular wall 121 can be interference-fitted or transition-fitted, or can be completely bonded or partially bonded. The first annular wall 111 and the second annular wall 121 can be tightly fitted and connected by extrusion deformation, and will not be specifically limited here.

[0064] The multiple support structures 130 are hollow tubular structures. And the support structures 130 are arranged at intervals between the first plate 110 and the second plate 120. The multiple support structures 130 form the support for the first plate 110 and the second plate 120, and can be combined with the first plate 110 and the second plate 120 to form a stable support unit 100. Moreover, the support structure 130 formed by the cooperation of the first annular wall 111 and the second annular wall 121 has high rigidity and is not easily squeezed and deformed, which can effectively avoid the situation that the first plate 110 and the second plate 120 are bent or twisted, thereby improving the structural strength of the support unit 100. The support unit 100 bears the load on the first plate 110 or the second plate 120 through the support structure 130 and distributes the load to the multiple support structures 130, thereby enhancing the bearing capacity of the support unit 100.

[0065] Moreover, the first annular wall 111 and the second annular wall 121 are tightly fitted together, which makes the connection between the first plate 110 and the second plate 120 more secure, thereby improving the connection stability of the first plate 110 and the second plate 120 .

[0066] In addition, the support structure 130 is a hollow structure, and cavities are formed between the first plate 110 and the second plate 120 and inside the support structure 130. This can effectively reduce the weight of the support unit 100 while ensuring the structural strength of the support unit 100, making the support unit 100 lighter and easier to carry.

[0067] It is understood that the first annular wall 111 can be formed by stamping the first plate 110, that is, the first annular wall 111 and the first plate 110 are integrally formed. The first annular wall 111 can also be fixedly connected to the first plate 110 by welding, riveting, or other methods, which are not specifically limited here. When the first annular wall 111 is formed by stamping the first plate 110, the first plate 110 can be punched first and then punched to form the first annular wall 111, or the first plate 110 can be punched first and then punched to form the first annular wall 111.

[0068] Reference Figure 3 As shown, in some embodiments of the present invention, a second edge 122 is extended outward from the upper end of the second annular wall 121 (i.e., the end away from the second plate 120). The second edge 122 can be formed by bending the second annular wall 121, or formed integrally with the second plate 120. The second edge 122 is aligned with the first plate 110, thereby further aligning the first annular wall 111 and the second annular wall 121, providing a more secure connection and improving the structural strength of the support structure 130. Furthermore, the second edge 122 can support the first plate 110 and the connection between the first plate 110 and the first annular wall 111, allowing the second annular wall 121 to more stably withstand the load of the first plate 110, thereby improving the load-bearing capacity of the support unit 100. In addition, the second edge 122 can be formed as an arc-shaped chamfer, so that when the first plate 110 and the second plate 120 are joined, the second edge 122 has a guiding function, and can guide the first annular wall 111 to be sleeved into the second annular wall 121, thereby making the first plate 110 and the second plate 120 joined more smoothly and improving assembly efficiency.

[0069] Reference Figure 3As shown, in some embodiments of the present invention, a first guide edge 113 is provided at the connection between the first plate 110 and the first annular wall 111. The first guide edge 113 can be integrally formed with the first annular wall 111, thereby optimizing the stress concentration problem at the connection between the first plate 110 and the first annular wall 111. The first guide edge 113 is aligned with the second edge 122, thereby achieving a more stable connection between the first guide edge 113 and the second edge 122. The second edge 122 and the first guide edge 113, as well as the first annular wall 111 and the second annular wall 121, together form a support structure 130, which can further improve the structural strength and stability of the support structure 130, thereby further enhancing the load-bearing capacity of the support unit 100.

[0070] Reference Figure 3 As shown, in some embodiments of the present invention, the longitudinal cross-section of the first guide edge 113 is an arc. The arc-shaped first guide edge 113 can improve the connection strength between the first plate 110 and the first annular wall 111, effectively reducing stress concentration. It is understood that the longitudinal cross-section of the first guide edge 113 can be understood as the cross-section formed by the plane where the axis of the first annular wall 111 is located cutting the first guide edge 113. The longitudinal cross-section of the second edge 122 is an arc that matches the first guide edge 113. The arc-shaped second edge 122 can improve the connection strength between the second annular wall 121, effectively reducing stress concentration, and the second edge 122 provides better support for the first plate 110 and the first guide edge 113. It is understood that the longitudinal cross-section of the second edge 122 can be understood as the cross-section formed by the plane where the axis of the second annular wall 121 is located cutting the second edge 122.

[0071] Reference Figure 6 、 Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first annular wall 111 is formed by deforming the first plate 110 toward the second plate 120, for example, by a deformation method such as stamping. The deformation method can improve the connection strength between the first annular wall 111 and the first plate 110, thereby improving the structural strength of the first plate 110 and the first annular wall 111, and further improving the load-bearing capacity of the support unit 100. One end of the first annular wall 111 is connected to the first plate 110, and the other end extends away from the first plate 110 and penetrates the second plate 120. The first annular wall 111 penetrates the second plate 120 and forms a through groove 114 in the first annular wall 111. The through groove 114 runs between the first plate 110 and the second plate 120, thereby forming a plurality of holes in the support unit 100. The design of the holes can provide the support unit 100 with a water-removing function, allowing the support unit 100 to be used in an outdoor environment, extending its service life, facilitating the cleaning of the platform plate 1000, and facilitating the ventilation of the goods.

[0072] Reference Figure 3 As shown, it can be understood that the inner diameter of the first annular wall 111 of this embodiment at the end away from the first plate 110 is greater than the inner diameter at the end close to the first plate 110. That is, the inner diameter of the cross section of the first annular wall 111 gradually increases in the direction away from the first plate 110. It should be noted that in order to achieve the above structure, the first annular wall 111 can be extruded outward, for example, by means of expansion or expansion, which is not specifically limited here. For example, the entire first annular wall 111 can be extruded so that the inner diameter of the cross section of the first annular wall 111 gradually increases from the end connected to the first plate 110 to the end away from the first plate 110; or the first annular wall 111 can be extruded at the end away from the first plate 110 so that the inner diameter of the cross section of part of the first annular wall 111 gradually increases. After the first annular wall 111 is squeezed, the connection between the first annular wall 111 and the second annular wall 121 can be made more secure, and the first annular wall 111 and the second annular wall 121 form a tapered structure, which can prevent the second plate 120 from falling off the first plate 110, thereby improving the structural stability of the support unit 100 and making the structural strength and bearing capacity of the support unit 100 higher.

[0073] Reference Figure 3 As shown, it can be understood that the longitudinal section of the first annular wall 111 is inclined relative to the axis of the first annular wall 111. Here, the longitudinal section of the first annular wall 111 can be understood as the cross-section formed by the plane containing the axis of the first annular wall 111 and cutting through the first annular wall 111. By tilting the first annular wall 111 in this embodiment, the first annular wall 111 and the second annular wall 121 form a tapered structure, preventing the second plate 120 from separating from the first plate 110 and further improving the structural stability of the support unit 100. Furthermore, the inclination angle ranges from 1 to 3 degrees. Within this parameter range, the manufacturing difficulty is reduced while ensuring the structural stability of the support unit 100.

[0074] Reference Figure 7 and Figure 8As shown, it can be understood that the cross-sectional profile of the through groove 114 is circular, making the processing of the support unit 100 simpler and the bearing effect better. The through grooves 114 can be evenly distributed on the support unit 100, thus achieving a better structural layout of the support unit 100. In the support unit 100 of this embodiment, the inner diameter range of the through groove 114 is 35 mm to 45 mm, and the distance range between the axes of adjacent through grooves 114 is 40 mm to 60 mm. Within the above parameter range, the support structure 130 on the support unit 100 can achieve a better structural arrangement on the first plate 110 and the second plate 120, so that the support unit 100 can disperse the load to each support structure 130 during bearing, reduce stress concentration, and thus improve the bearing capacity of the support unit 100. Moreover, the support unit 100 is easier to process and has a higher yield rate.

[0075] Referring to Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first annular wall 111 is formed with a through groove 114, and the cross-sectional profile of the through groove 114 is circular. Therefore, both the first annular wall 111 and the second annular wall 121 are annular columnar structures, making the processing and assembly of the first plate 110 and the second plate 120 more convenient, reducing the difficulty of processing and assembly, and improving production efficiency. Of course, the cross-sectional profile of the through groove 114 can also be triangular, quadrilateral, hexagonal, etc., that is, the cross-sections of the first annular wall 111 and the second annular wall 121 are triangular, quadrilateral, hexagonal and other structures, which will not be specifically limited here. The support unit 100 adopting the above structure also has the advantages of high structural strength and strong bearing capacity.

[0076] Continuing to refer to Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the first annular wall 111 is formed by stamping the first plate 110. The first annular wall 111 is directly formed by stamping the first plate 110, which can simplify the processing procedure, improve production efficiency, and at the same time reduce the metal material consumption, which can not only save costs but also reduce the weight of the support unit 100. In some embodiments of the present invention, the second annular wall 121 is formed by stamping the second plate 120. The second annular wall 121 is directly formed by stamping the first plate 110, which can simplify the processing procedure, improve production efficiency, and at the same time reduce the metal material consumption, which can not only save costs but also reduce the weight of the support unit 100.

[0077] Referring to Figure 3As shown, in some embodiments of the present invention, a first edge 112 extends outward at the lower end of the first annular wall 111 (i.e., the end far from the first plate 110), and the first edge 112 can be formed by bending the first annular wall 111. The first edge 112 is in contact with the second plate 120, and the first edge 112 presses against the second plate 120. The first edge 112 can be connected to the second plate 120 by press-fitting, or welded to the second plate 120, or riveted to the second plate 120, and the specific connection method is not specifically limited herein. Thus, the first annular wall 111 and the second annular wall 121 are more closely fitted, the connection is more firm, and the structural strength of the support structure 130 is improved. Moreover, the first edge 112 can support the second plate 120 and the connection between the second plate 120 and the second annular wall 121, so that the first annular wall 111 can more stably bear the load of the second plate 120, thereby enhancing the bearing capacity of the support unit 100.

[0078] Continue to refer to Figure 3 As shown, in some embodiments of the present invention, a second guiding edge 123 is provided at the connection between the second plate 120 and the second annular wall 121. The second guiding edge 123 can be integrally formed with the second annular wall 121, which can optimize the stress concentration problem at the connection position between the second plate 120 and the second annular wall 121. The second guiding edge 123 is in contact with the first edge 112, so that a more stable connection can be achieved between the second guiding edge 123 and the first edge 112. The first edge 112 and the second guiding edge 123, as well as the first annular wall 111 and the second annular wall 121, jointly form the support structure 130, which can further improve the structural strength and structural stability of the support structure 130, thereby further enhancing the bearing capacity of the support unit 100.

[0079] A card slot 1231 is formed on the second guiding edge 123, and the first edge 112 is clamped in the card slot 1231, which can make the connection between the first edge 112 and the second guiding edge 123 more stable.
