[0055] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0056] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to 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 invention.

[0057] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0058] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0059] Reference Figure 1As shown, a platform 1000 according to an embodiment of the present invention includes a pallet 200 for carrying goods, the pallet 200 being formed by assembling a plurality of support units 100. In this embodiment, the platform 1000 achieves load-bearing capacity through the support units 100, exhibiting strong load-bearing capacity and allowing for use in multiple stages of logistics transportation.

[0060] Reference Figure 2 and Figure 3a As shown, a support unit 100 according to one embodiment of the present invention can be used on panel structures such as platform boards and box bodies to bear loads. The support unit 100 in this embodiment includes a first plate 110 and a second plate 120 spaced apart. The first plate 110 and the second plate 120 can be made of metal materials, such as sheet metal parts. Using sheet metal parts for the first plate 110 and the second plate 120 simplifies the manufacturing process of the support unit 100, and the resulting support unit 100 has high structural strength and light weight. It is understood that the first plate 110 and the second plate 120 can also be made of other thin metal sheet materials. Using metal for the first plate 110 and the second plate 120 facilitates recycling and reuse, is environmentally friendly, and saves resources.

[0061] It is understandable that both the first plate 110 and the second plate 120 are made of galvanized sheet or electrolytic sheet. Galvanized sheet and electrolytic sheet have many advantages, such as high strength, high ductility, corrosion resistance, nuclear radiation resistance, high efficiency in reflecting ultraviolet rays, easy processing, light weight, recyclability, pest resistance, and low carbon and environmental protection.

[0062] Reference Figure 1 As shown, for example, when the support unit 100 is used to manufacture the platform, the support unit 100 is made of galvanized sheet or electrolytic sheet to make the platform, which fully meets the usage requirements of the platform. Moreover, the platform made of galvanized sheet or electrolytic sheet generates very little waste after disassembly, and the recycling rate of the disassembled galvanized sheet or electrolytic sheet is more than 80%, which meets the environmental performance requirements.

[0063] Continue to refer to Figure 2 and Figure 3aAs shown, it can be understood that the lower end face of the first plate 110 is provided with a plurality of first annular walls 111 spaced apart along the length and width directions of the first plate 110. The plurality of first annular walls 111 extend in a direction perpendicular to the first plate 110, and the first annular walls 111 are hollow cylindrical structures that are open from top to bottom. The upper end face of the second plate 120 is provided with a plurality of second annular walls 121 spaced apart along the length and width directions of the second plate 120. The plurality of second annular walls 121 extend in a direction perpendicular to the second plate 120, and the second annular walls 121 are hollow cylindrical structures that are open from top to bottom. It should be noted that the lower end face and the upper end face referred to here are only for this specific embodiment and are not limited to their absolute positions, but should be understood as their relative positions. For example, the lower end face of the first plate 110 is the end face of the first plate 110 facing the second plate 120, and the upper end face of the second plate 120 is the end face of the second plate 120 facing the first plate 110.

[0064] Multiple second annular walls 121 are correspondingly arranged with multiple first annular walls 111. The second annular walls 121 are fitted onto the outer side of the first annular walls 111. The second annular walls 121 and the first annular walls 111 can be configured for a tight fit connection, thereby allowing the first annular walls 111 and the second annular walls 121 to fit together 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 a tight fit connection can be understood as a connection method in which there is no relative movement between the first annular walls 111 and the second annular walls 121. The first annular walls 111 and the second annular walls 121 can be an interference fit or a transition fit connection, or a fully fitted or partially fitted connection. The first annular walls 111 and the second annular walls 121 can achieve a tight fit connection through extrusion deformation, which is not specifically limited here.

[0065] Multiple support structures 130 are hollow cylindrical structures. These support structures 130 are spaced apart between the first plate 110 and the second plate 120, forming a support for both plates. They combine with the first and second plates 110 to form a stable support unit 100. Furthermore, the support structures 130, formed by the cooperation of the first annular wall 111 and the second annular wall 121, have high rigidity and are not easily deformed by compression, effectively preventing bending or torsion of the first and second plates 110 and 120, 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 structures 130, distributing the load across the multiple support structures 130, thus enhancing the load-bearing capacity of the support unit 100.

[0066] Moreover, the tight fit between the first ring wall 111 and the second ring wall 121 makes the connection between the first plate 110 and the second plate 120 more secure, thereby improving the connection stability between the first plate 110 and the second plate 120.

[0067] In addition, the support structure 130 is a hollow structure, with cavities 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 transport.

[0068] 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 structures; the first annular wall 111 can also be fixedly connected to the first plate 110 by welding, riveting, etc., 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 stamped to form the first annular wall 111, or the first plate 110 can be stamped first and then punched to form the first annular wall 111.

[0069] Reference Figure 3a As shown, in some embodiments of the present invention, the upper end of the second annular wall 121 (i.e., the end away from the second plate 120) extends outward with a second edge 122. The second edge 122 can be formed by bending the second annular wall 121 or integrally formed by the second plate 120. The second edge 122 fits against the first plate 110, thereby making the first annular wall 111 and the second annular wall 121 fit more closely and the connection more secure, thus improving the structural strength of the support structure 130. Moreover, the second edge 122 can support the first plate 110 and the connection between the first plate 110 and the first annular wall 111, so that the second annular wall 121 can more stably bear 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, which can guide the first ring wall 111 to be fitted into the second ring wall 121, thereby making the joining of the first plate 110 and the second plate 120 smoother and improving assembly efficiency.

[0070] Reference Figure 3aAs 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 processed with the first annular wall 111, which can optimize the stress concentration problem at the connection position of the first plate 110 and the first annular wall 111. The first guide edge 113 fits against the second edge 122, thereby enabling a more stable connection between the first guide edge 113 and the second edge 122. The second edge 122, the first guide edge 113, 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 structural stability of the support structure 130, thereby further enhancing the load-bearing capacity of the support unit 100.

[0071] Reference Figure 3a As shown, in some embodiments of the present invention, the longitudinal section of the first guide edge 113 is arc-shaped. The arc-shaped structure of the 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 can be understood that the longitudinal section of the first guide edge 113 can be understood as a cross-section formed by cutting the first guide edge 113 with the plane containing the axis of the first annular wall 111. The longitudinal section of the second edge 122 is arc-shaped, matching the first guide edge 113. The arc-shaped structure of the 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 can be understood that the longitudinal section of the second edge 122 can be understood as a cross-section formed by cutting the second edge 122 with the plane containing the axis of the second annular wall 121.

[0072] Reference Figure 4 and Figure 5a 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 stamping or other deformation methods. This deformation process improves the connection strength between the first annular wall 111 and the first plate 110, thereby increasing the structural strength of the first plate 110 and the first annular wall 111, and ultimately enhancing 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 through the second plate 120. The first annular wall 111 penetrates through the second plate 120, forming a through groove 114 that runs between the first plate 110 and the second plate 120, thus creating multiple holes on the support unit 100. The design of these holes enables the support unit 100 to have a water-draining function, allowing it to be used in outdoor environments, increasing its service life, facilitating cleaning of the platform 1000, and also promoting ventilation of goods.

[0073] Reference Figure 3a As shown, it can be understood that in this embodiment, the inner diameter of the end of the first annular wall 111 away from the first plate 110 is larger than the inner diameter of the end closer to the first plate 110. That is, along the direction away from the first plate 110, the inner diameter of the cross-section of the first annular wall 111 gradually increases. It should be noted that, in order to achieve the above structure, the first annular wall 111 can be processed by extruding it outward, for example, by spreading or expanding the hole, etc., which are 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 end of the first annular wall 111 away from the first plate 110 can be extruded, so that the inner diameter of the cross-section of a portion of the first annular wall 111 gradually increases. After the first ring wall 111 is compressed, the connection between the first ring wall 111 and the second ring wall 121 becomes stronger. Moreover, the first ring wall 111 and the second ring wall 121 form a tapered structure, which can prevent the second plate 120 from coming off the first plate 110, improve the structural stability of the support unit 100, and make the support unit 100 have higher structural strength and stronger load-bearing capacity.

[0074] Reference Figure 3a As shown, it can be understood that the longitudinal section of the first annular wall 111 is inclined relative to its axis. Here, the longitudinal section of the first annular wall 111 can be understood as a cross-section formed by cutting the first annular wall 111 with the plane containing its axis. In this embodiment, by inclining the first annular wall 111, the first annular wall 111 and the second annular wall 121 form a tapered structure, which prevents the second plate 120 from detaching from the first plate 110, further improving the structural stability of the support unit 100. Moreover, the inclination angle ranges from 1 degree to 3 degrees. Within this parameter range, the manufacturing difficulty is low, and the structural stability of the support unit 100 is guaranteed.

[0075] Reference Figure 5a As shown, it can be understood that the cross-sectional profile of the through groove 114 is circular, which simplifies the processing of the support unit 100 and improves its load-bearing capacity. The through grooves 114 can be evenly distributed on the support unit 100, thereby achieving a better structural layout of the support unit 100. In this embodiment, the inner diameter of the through groove 114 of the support unit 100 ranges from 35mm to 45mm, and the distance between the axes of adjacent through grooves 114 ranges from 40mm to 60mm. Satisfying the above parameter range allows the support structure 130 on the support unit 100 to achieve a better structural arrangement on the first plate 110 and the second plate 120, so that the support unit 100 can distribute the load to each support structure 130 when bearing load, reducing stress concentration and thus improving the load-bearing capacity of the support unit 100.

[0076] Reference Figure 5a As shown, in some embodiments of the present invention, the first annular wall 111 is formed with a through groove 114, the cross-sectional profile of which is circular. Therefore, both the first annular wall 111 and the second annular wall 121 are circular 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, etc., which are not specifically limited here. The support unit 100 using the above structure also has the advantages of high structural strength and strong load-bearing capacity.

[0077] Continue to refer to Figure 5a As shown, in some embodiments of the present invention, the first annular wall 111 is formed by stamping using a first plate 110. Directly stamping the first annular wall 111 using the first plate 110 simplifies the processing steps, improves production efficiency, and reduces metal usage, thus saving costs and reducing the weight of the support unit 100. In some embodiments of the present invention, the second annular wall 121 is formed by stamping using a second plate 120. Directly stamping the second annular wall 121 using the first plate 110 simplifies the processing steps, improves production efficiency, and reduces metal usage, thus saving costs and reducing the weight of the support unit 100.

[0078] Reference Figure 3a As shown, in some embodiments of the present invention, the lower end of the first annular wall 111 (i.e., the end away from the first plate 110) extends outward with a first edge 112, which can be formed by bending the first annular wall 111. The first edge 112 fits against the second plate 120 and is pressed against the second plate 120. The first edge 112 can be connected to the second plate 120 by pressing, welding, or riveting; the specific connection method is not specifically limited here. This makes the first annular wall 111 and the second annular wall 121 fit more closely and the connection is more secure, improving the structural strength of the support structure 130. 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, allowing the first annular wall 111 to more stably bear the load of the second plate 120, thereby improving the load-bearing capacity of the support unit 100.

[0079] Continue to refer to Figure 3aAs shown, in some embodiments of the present invention, a second guide edge 123 is provided at the connection between the second plate 120 and the second annular wall 121. The second guide edge 123 can be integrally processed with the second annular wall 121, which can optimize the stress concentration problem at the connection position of the second plate 120 and the second annular wall 121. The second guide edge 123 fits against the first edge 112, thereby enabling a more stable connection between the second guide edge 123 and the first edge 112. The first edge 112 and the second guide edge 123, as well as the first annular wall 111 and the second annular wall 121, together form the support structure 130, which can further improve the structural strength and structural stability of the support structure 130, thereby further enhancing the load-bearing capacity of the support unit 100.

[0080] The second guide edge 123 has a groove 1231, and the first edge 112 engages with the groove 1231, making the connection between the first edge 112 and the second guide edge 123 more stable. The structure of the groove 1231 can be formed by pressing the first edge 112 onto the second guide edge 123, thereby compressing the second guide edge 123. This method is simpler and more convenient to manufacture, and the structure is more stable. Of course, the structure of the groove 1231 can also be achieved using other manufacturing methods.

[0081] Continue to refer to Figure 3a As shown, in some embodiments of the present invention, the lowest position of the first edge 112 is located in the plane where the second plate 120 is located, thereby making the lower end surface of the support unit 100 a relatively smooth surface, avoiding the situation of cutting hands when personnel handle it, or interference with transportation equipment (such as forklifts) leading to instability of the center of gravity.

[0082] Reference Figure 3a As shown, in some embodiments of the present invention, a cavity 140 is formed between the first plate 110 and the second plate 120. A support structure 130 formed by the first annular wall 111 and the second annular wall 121 is provided in the cavity 140, which can cooperate with the first plate 110 and the second plate 120 to support the shape of the cavity 140; and the support structure 130 makes the cavity 140 a sealed space to prevent foreign objects, such as water, from entering the cavity 140.

[0083] It should be noted that, in this embodiment of the invention, the depth of the cavity 140 is in the range of 12mm to 20mm. Within this range, the support structure 130 ensures that the support unit 100 has sufficient compressive strength, guaranteeing that the cavity 140 will not be deformed by compression, thereby making the support unit 100 more durable.

[0084] Reference Figure 3b and Figure 3cAs shown, in some embodiments of the present invention, the outer periphery of the first plate 110 is provided with a first folded edge 115, and the outer periphery of the second plate 120 is provided with a second folded edge 124. The first folded edge 115 and the second folded edge 124 are fixedly connected. The cooperative structure of the first folded edge 115 and the second folded edge 124 can close the edge of the support unit 100, preventing foreign objects from entering the cavity 140 from the edge of the support unit 100 through the gap between the first plate 110 and the second plate 120, thereby improving the stability of the support unit 100. It should be noted that the structure of the first folded edge 115 and the second folded edge 124 can be a connection structure commonly used on sheet metal parts, or a folded edge structure fixed by fasteners such as bolts, or a folded edge structure fixed by welding, riveting, etc., and is not specifically limited here.

[0085] Reference Figures 1 to 5b As shown, a platform 1000 according to an embodiment of the present invention includes the support unit 100 of the above embodiments. The embodiment of the present invention uses the support unit 100 of the first aspect embodiment. The support unit 100 comprises a first plate 110 and a second plate 120 arranged at intervals. A plurality of first annular walls 111 on the first plate 110 are correspondingly sleeved on the outer sides of a plurality of second annular walls 121 on the second plate 120, and the first annular walls 111 and second annular walls 121 are connected to achieve a tight connection between the first plate 110 and the second plate 120, improving the stability of the connection. The first annular walls 111 and second annular walls 121 are connected to form a support structure 130 for supporting the first plate 110 and the second plate 120. The support structure 130 is arranged at intervals between the first plate 110 and the second plate 120, and can combine with the first plate 110 and the second plate 120 to form a stable support unit 100, giving the platform 1000 the advantages of high structural strength and strong load-bearing capacity. Cavities are formed between the first plate 110 and the second plate 120, and within the supporting structure 130, which can effectively reduce the weight of the platform 1000 while ensuring the structural strength of the platform 1000.

[0086] Since the platform 1000 adopts all the technical solutions of the support unit 100 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0087] Reference Figure 4As shown, in some embodiments of the present invention, the support unit 100 forms a pallet 200, which is formed by one or more support units 100. The bottom of the pallet 200 is provided with support feet 300, which support the pallet 200 and lift it off the bottom surface, thereby facilitating transport of the platform 1000 by forklifts or other transport vehicles. The support feet 300 can be made of metal, wood, or plastic. It is understood that the support feet 300 can be fixedly connected to the first plate 110 or the second plate 120.

[0088] Reference Figure 4 and Figure 5b As shown, in some embodiments of the present invention, the first plate 110 is provided with a third through hole 116 and a third annular wall 117. The third annular wall 117 is located on the outer periphery of the third through hole 116 and can be formed by stamping. The third annular wall 117 extends toward and abuts against the second plate 120, thereby supporting the first plate 110 on the second plate 120 through the third annular wall 117. Moreover, the third annular wall 117 seals the cavity 140, thereby preventing foreign objects from entering the cavity 140.

[0089] Continue to refer to Figure 5b As shown, the second plate 120 is provided with a fourth through hole 125 and a fourth annular wall 126. The fourth annular wall 126 is located on the outer periphery of the fourth through hole 125 and extends away from the first plate 110. The fourth annular wall 126 can be formed by stamping. The diameter of the third through hole 116 is smaller than the diameter of the fourth through hole 125, thereby ensuring that the third annular wall 117 can stably support the second plate 120.

[0090] Continue to refer to Figure 5b As shown, the support leg 300 has an open and hollow structure at the top. The support leg 300 is fitted onto the fourth annular wall 126, making installation more convenient and lighter. The support leg 300 has a conical structure, and its outer diameter gradually decreases in the direction away from the support plate 200. The third through hole 116, the fourth through hole 125 and the upper end of the support leg 300 are connected, so that when the platform 1000 is placed, the support legs 300 of adjacent platform 1000s can nest with each other, so that the support plates 200 of adjacent platform 1000s can be stacked, thereby greatly reducing the space required for storing the platform 1000.

[0091] Reference Figure 5bAs shown, in some embodiments of the present invention, the hollow support foot 300 includes a bottom wall 310 and a peripheral wall 320. One end of the peripheral wall 320 is connected to the bottom wall 310, making the connection of the support foot 300 more stable and increasing the friction of the contact surface of the support foot 300. The other end of the peripheral wall 320 is connected to the outer side of the fourth annular wall 126, making the connection between the support foot 300 and the support plate 200 more reliable and improving the connection reliability of the platform 1000.

[0092] It is understood that in some embodiments of the present invention, the end of the peripheral wall 320 away from the bottom wall 310 is provided with an installation edge 330, which abuts against the second plate 120, further improving the connection stability between the support foot 300 and the second plate 120, improving the installation efficiency of the support foot 300 and the second plate 120, and making the structure of the platform 1000 more reliable.

[0093] Continue to refer to Figure 5b As shown, the bottom wall 310 is provided with a fifth through hole 340, which is connected to the third through hole 116, the fourth through hole 125 and the inner cavity of the support foot 300, thereby realizing drainage between the contact surface of the first plate 110 and the support foot 300, preventing water from being trapped inside the support foot 300, and thus improving the service life of the platform plate 1000.

[0094] Continue to refer to Figure 5b As shown, in some embodiments of the present invention, the support foot 300 is integrally manufactured, such as by stamping or injection molding, which makes the structure more stable, the processing simpler, the weight lighter, and the installation and replacement easier.

[0095] Reference Figure 4 As shown, in some embodiments of the present invention, the height between the bottom surface of the pallet 200 and the bottom surface of the support leg 300 is configured to allow the fork of a forklift to insert, thereby facilitating the transport of the platform 1000 by the forklift, improving transport efficiency and enhancing transport safety.

[0096] Reference Figure 6 As shown, an embodiment of the present invention discloses a method for manufacturing a platform board, used to produce a metal platform board. The metal platform board has high structural strength and load-bearing capacity, and the metal material is recyclable, making it energy-saving and environmentally friendly. The platform board of this embodiment includes the following steps:

[0097] S601: A first metal plate 1400 is provided. The dimensions of the first metal plate 1400 are selected according to the dimensions of the supporting surface of the platform. The thickness and material of the first metal plate 1400 are selected according to the load-bearing requirements of the platform. It is understood that the first metal plate 1400 in this embodiment of the invention is a sheet metal part, which has high strength, light weight, and is easy to process.

[0098] S602: Multiple first through holes 1401 are machined at intervals along the length and width directions of the first metal plate 1400. (Refer to...) Figure 14 As shown, it can be understood that the multiple first through holes 1401 are arranged in an array or evenly distributed. The multiple first through holes 1401 can be processed by punching or other methods. For example, the multiple first through holes 1401 are arranged in multiple rows at intervals along the length direction of the first metal plate 1400, and each row is arranged with multiple first through holes 1401 at intervals along the width direction of the first metal plate 1400, with the corresponding first through holes 1401 in adjacent rows being staggered.

[0099] S603: First annular walls 1402 are pressed out along the positions of the multiple first through holes 1401. (Refer to...) Figure 14 and Figure 15 As shown, it can be understood that the first annular wall 1402 can be processed from the first metal plate 1400 by stamping or other processing methods. The first annular wall 1402 is formed on the outer periphery of the first through hole 1401. The first annular wall 1402 can extend in a direction perpendicular to the first metal plate 1400 or extend towards the second metal plate 1500, forming a hollow cylindrical structure. It can be understood that after the first annular wall 1402 is pressed, the diameter of the hole formed by the first annular wall 1402 is larger than the diameter of the first through hole 1401 processed in step S602. The inner hole formed by the first annular wall 1402 facilitates drainage of the first metal plate 1400 and also increases the overall strength of the first metal plate 1400.

[0100] S604: A second metal plate 1500 is provided. The dimensions of the second metal plate 1500 are selected based on the dimensions of the supporting surface of the platform. The thickness and material of the second metal plate 1500 are selected based on the load-bearing requirements of the platform. To improve production efficiency, the dimensions of the second metal plate 1500 are basically the same as those of the first metal plate 1400. Of course, the parameters of the second metal plate 1500 (e.g., dimensions, thickness, or material) can also differ from those of the first metal plate 1400, and can be designed according to the specific needs of use. It is understood that the second metal plate 1500 in this embodiment of the invention is made of sheet metal, which has high strength, light weight, and is easy to process.

[0101] S605: Multiple second through holes 1501 are machined at intervals along the length and width directions of the second metal plate 1500. (Refer to...) Figure 14As shown, it can be understood that the multiple second through holes 1501 are arranged in an array or evenly distributed. The arrangement of the second through holes 1501 is the same as that of the first through holes 1401. The multiple second through holes 1501 can be processed by punching or other methods. For example, the multiple second through holes 1501 are arranged in multiple rows along the length direction of the second metal plate 1500, and each row is arranged with multiple second through holes 1501 at intervals along the width direction of the second metal plate 1500, with the corresponding second through holes 1501 in adjacent rows being staggered.

[0102] S606: Second annular walls 1502 are pressed out along the positions of multiple second through holes 1501. (Refer to...) Figure 14 and Figure 15 As shown, it is understood that the second annular wall 1502 can be processed from the second metal plate 1500 by stamping or other processing methods. The second annular wall 1502 is formed on the outer periphery of the second through hole 1501. The second annular wall 1502 can extend in a direction perpendicular to the second metal plate 1500 or extend towards the first metal plate 1400, forming a hollow cylindrical structure. It is understood that after the second annular wall 1502 is pressed, the diameter of the hole formed by the second annular wall 1502 is larger than the diameter of the second through hole 1501 processed in step S605. The inner hole formed by the second annular wall 1502 facilitates drainage of the second metal plate 1500 and also increases the overall strength of the second metal plate 1500.

[0103] S607: Place the first metal plate 1400 and the second metal plate 1500 mirror-symmetrically, and align the first annular wall 1402 and the second annular wall 1502. (Refer to...) Figure 15 and Figure 16 As shown, it can be understood that the second metal plate 1500, which has the second ring wall 1502, can be flipped up and down to form a mirror-symmetrical arrangement with the first metal plate 1400. Moreover, the second ring wall 1502 on the second metal plate 1500 is aligned one-to-one with the first ring wall 1402 on the first metal plate 1400, which improves the accuracy of the pairing and installation of the first metal plate 1400 and the second metal plate 1500 and reduces the difficulty of production and processing.

[0104] It should be noted that the processing order of the first metal plate 1400 and the second metal plate 1500 is interchanged, and will not be specifically limited here.

[0105] S608: The first metal plate 1400 and the second metal plate 1500 are joined together, so that the second annular wall 1502 is fitted onto the outside of the first annular wall 1402 and pressed tightly against the first annular wall 1402. (Refer to...) Figure 17 and Figure 18As shown, it can be understood that the press-fit between the first ring wall 1402 and the second ring wall 1502 can be interpreted as a connection method in which there is no relative movement between the first ring wall 111 and the second ring wall 121. The first ring wall 111 and the second ring wall 121 can be an interference fit or a transition fit connection, or a fully fitted or partially fitted connection. The press-fit between the first ring wall 1402 and the second ring wall 1502 enables a stable connection between the first metal plate 1400 and the second metal plate 1500, improving the overall stability of the platform. Furthermore, the first ring wall 1402 and the second ring wall 1502 are connected to form a support structure. The support structure can be a hollow cylindrical structure, which can support the first metal plate 1400 and the second metal plate 1500, thereby allowing the first metal plate 1400 and the second metal plate 1500 to join together to form a stable support surface for the platform, thus improving the structural strength of the platform. The support structure adopts a structure in which the second ring wall 1502 is sleeved on the outside of the first ring wall 1402, which can form a double-layer structure, improve the strength of the support structure, and thus enhance the load-bearing capacity of the platform.

[0106] S609: Provide support legs. It is understood that the support legs are generally made of metal. Furthermore, to reduce the overall weight of the platform and facilitate handling, the support legs are typically machined from sheet metal. For example, the support legs can be stamped parts, i.e., machined into a hollow structure, thereby effectively reducing weight while meeting structural strength requirements. Alternatively, the support legs can also be made of lightweight materials with a certain strength, such as plastic or wood.

[0107] S610: Securely connect the support leg to the second metal plate 1500. It is understood that multiple support legs are provided, and the specific number of support legs is designed according to parameters such as the load-bearing requirements of the platform and the load-bearing capacity of each support leg. For example, there are 9 support legs, with 8 arranged at intervals along the outer perimeter of the platform's support surface, and the other 1 located at the center of the platform's support surface.

[0108] The method for manufacturing a platform plate according to an embodiment of the present invention involves processing a first annular wall 1402 on a first metal plate 1400 and a second annular wall 1502 on a second metal plate 1500, and mirror-symmetrically joining the first metal plate 1400 and the second metal plate 1500 so that the second annular wall 1502 is fitted onto the outside of the first annular wall 1402 and tightly connected to the first annular wall 1402. This method achieves the processing of a metal platform plate, which is simple in process, reduces production costs, and produces a platform plate with high structural strength, strong load-bearing capacity, and long service life.

[0109] Reference Figure 7 As shown, it can be understood that after step S608, the following steps are included:

[0110] S701: The edge of the first annular wall 1402 is bent outward to form a first edge 1403. The first edge 1403 is formed at the end of the first annular wall 1402 away from the first metal plate 1400. The first edge 1403 can support the second annular wall 1502 or the second metal plate 1500, thereby improving the support effect of the first metal plate 1400 and the second metal plate 1500. The first edge 1403 can restrict the degree of freedom of the second annular wall 1502 in the axial direction, preventing the first metal plate 1400 and the second metal plate 1500 from separating, further improving the stability of the connection between the first metal plate 1400 and the second metal plate 1500, and thus strengthening the structural strength of the platform plate.

[0111] S702: Press the first edge 1403 firmly onto the second metal plate 1500. The first edge 1403 can be connected to the second metal plate 1500 by pressing, welding, or riveting; the specific connection method is not limited here. The first edge 1403 makes the connection between the first metal plate 1400 and the second metal plate 1500 more stable, thus making the overall structure of the platform more stable.

[0112] Reference Figure 8 As shown, it can be understood that step S606 specifically includes the following steps:

[0113] S801: Second annular walls 1502 are pressed out along the positions of multiple second through holes 1501. The second annular walls 1502 are formed by pressing along the outer periphery of the second through holes 1501. The inner hole formed by the second annular walls 1502 facilitates drainage of the second metal plate 1500, and also increases the overall strength of the second metal plate 1500, improving its bending resistance.

[0114] S802: A second guide edge 1504 is machined at the connection between the second metal plate 1500 and the second annular wall 1502 to fit against the first edge 1403. It is understood that the second guide edge 1504 and the second annular wall 1502 can be machined in one step or in stages. The fit between the second guide edge 1504 and the first edge 1403 makes the connection between the second annular wall 1502 and the first annular wall 1402 more secure, resulting in more even stress distribution on the platform and better load-bearing capacity. Furthermore, it allows the first edge 1403 to better support the second annular wall 1502, improving the structural strength of the platform. In addition, the first edge 1403, through the second guide edge 1504, further restricts the axial freedom of the second annular wall 1502, preventing the first metal plate 1400 and the second metal plate 1500 from separating, further improving the stability of the connection between the first metal plate 1400 and the second metal plate 1500.

[0115] Reference Figure 9 As shown, it can be understood that step S702 specifically includes the following steps:

[0116] S901: The first edge 1403 is pressed against the second annular wall 1502, causing the second annular wall 1502 to form a groove 1505 that accommodates at least a portion of the first edge 1403. It is understood that the first edge 1403 engages with the groove 1505, thereby making the connection between the first edge 1403 and the second annular wall 1502 more stable and reliable. Furthermore, the stable connection between the first edge 1403 and the second annular wall 1502 forms a stable support structure, thereby making the overall structure of the platform more stable and its load-bearing capacity stronger.

[0117] It should be noted that when a second guide edge 1504, which can fit against the first edge 1403, is machined at the connection between the second annular wall 1502 and the second metal plate 1500, a slot 1505 is formed on the second guide edge 1504. This allows the first edge 1403 to connect better with the second guide edge 1504, improving the stability of the connection between the first metal plate 1400 and the second metal plate 1500. Furthermore, it ensures that the first edge 1403 is flush with the surface of the second metal plate 1500, improving the stability of the platform during forklift handling and enhancing personnel safety during handling, thus reducing safety risks during platform use.

[0118] Reference Figure 10 As shown, it can be understood that after step S608, the following steps are included:

[0119] S1001: At least a portion of the first annular wall 1402 is pressed outwards to form a cross-section of the first annular wall 1402 whose inner diameter gradually increases in the direction away from the first metal plate 1400. It is understood that pressing the first annular wall 1402 outwards can be achieved by methods such as spreading or expanding the hole, and is not specifically limited here. For example, the entire first annular wall 1402 can be pressed, or only one end of the first annular wall 1402 away from the first metal plate 1400 can be pressed. After pressing, the longitudinal section of the first annular wall 1402 is inclined relative to its axis, and the angle of inclination can be designed to be between 1 degree and 3 degrees. Here, the longitudinal section of the first annular wall 1402 can be understood as a cross-section formed by cutting the first annular wall 1402 with the plane containing its axis. Therefore, by squeezing the first ring wall 1402, the connection between the first ring wall 1402 and the second ring wall 1502 can be made more secure. Moreover, the first ring wall 1402 and the second ring wall 1502 form a tapered structure, which can prevent the second metal plate 1500 from coming off the first metal plate 1400, further improving the structural stability of the platform plate, and making the platform plate stronger and more load-bearing.

[0120] Reference Figure 11 As shown, it can be understood that step S606 specifically includes the following steps:

[0121] S1101: Second annular walls 1502 are pressed out along the positions of multiple second through holes 1501. The second annular walls 1502 are formed by pressing along the outer periphery of the second through holes 1501. The inner hole formed by the second annular walls 1502 facilitates drainage of the second metal plate 1500, and also increases the overall strength of the second metal plate 1500, improving its bending resistance.

[0122] S1102: The edge of the second annular wall 1502 is bent outward to form a second edge 1503. The second edge 1503 is formed at the end of the second annular wall 1502 away from the second metal plate 1500. The second edge 1503 and the second annular wall 1502 can be formed in one process or in steps. The second edge 1503 can support the first annular wall 1402 or the first metal plate 1400, thereby improving the support effect of the first metal plate 1400 and the second metal plate 1500. In addition, the second edge 1503 can be formed into an arc-shaped chamfer, so that when the first metal plate 1400 and the second metal plate 1500 are joined, the second edge 1503 has a guiding function, which can guide the first annular wall 1402 to be fitted into the second annular wall 1502, thereby making the joining of the first metal plate 1400 and the second metal plate 1500 smoother and improving assembly efficiency.

[0123] Reference Figure 12 As shown, it can be understood that step S603 specifically includes the following steps:

[0124] S1201: First annular walls 1402 are pressed out along the positions of multiple first through holes 1401. The first annular walls 1402 are formed by pressing along the outer periphery of the first through holes 1401.

[0125] S1202: A first guide edge 1404 is machined at the connection between the first metal plate 1400 and the first annular wall 1402 to fit against the second edge 1503. It is understood that the first guide edge 1404 and the first annular wall 1402 can be machined in one step or in stages. The fit between the first guide edge 1404 and the second edge 1503 makes the connection between the first annular wall 1402 and the second annular wall 1502 more secure, resulting in more even stress distribution on the platform and better load-bearing capacity; moreover, it allows the second edge 1503 to better support the first annular wall 1402, improving the structural strength of the platform.

[0126] Reference Figure 13As shown, it can be understood that after step S608, the following steps are included:

[0127] S1301: The outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 are fixedly connected. It is understood that the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can be processed into mutually mating folded edges to achieve a stable connection, or they can be connected using fasteners such as bolts; no specific limitation is made here. The fixed connection of the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can prevent rainwater or foreign objects from entering the space between the first metal plate 1400 and the second metal plate 1500 during use, thus preventing corrosion and damage to the platform. For example, when the connection between the first metal plate 1400 and the second metal plate 1500 is achieved by using mutually cooperating folded edges, the folded edges can be processed before the joining step of the first metal plate 1400 and the second metal plate 1500, so that the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can be connected simultaneously during the connection process of the first ring wall 1402 and the second ring wall 1502. Alternatively, the step of connecting the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can be designed before or after the connection step of the first ring wall 1402 and the second ring wall 1502, which is not specifically limited here.

[0128] Reference Figure 14 As shown, it can be understood that both the first ring wall 1402 and the second ring wall 1502 are formed by stamping. The stamping process is mature, with high processing precision and high quality, which makes the structure of the first ring wall 1402 and the second ring wall 1502 stable, ensuring the structural strength of the platform and improving the quality of the product.

[0129] Reference Figure 15 As shown, it can be understood that both the first through hole 1401 and the second through hole 1501 are formed by punching. The punching process is simple, the technology is mature, the processing quality is high, and the processing accuracy is high, and the processing is safe and reliable.

[0130] Reference Figure 14 and Figure 15As shown, it can be understood that both the first through hole 1401 and the second through hole 1501 are circular holes, which makes them easier to process. Furthermore, processing these circular holes into the first annular wall 1402 and the second annular wall 1502 results in a circular cross-sectional profile, making the structure of the first annular wall 1402 and the second annular wall 1502 more stable and facilitating the joining and forming of the first metal plate 1400 and the second metal plate 1500, thus reducing processing difficulty. Of course, the first through hole 1401 and the second through hole 1501 can also be designed as triangular, quadrilateral, hexagonal, etc., and are not specifically limited here. Moreover, the above design facilitates the processing of the first annular wall 1402 into structures such as the first edge 1403 and the first guide edge 1404, and also facilitates the processing of the second annular wall 1502 into structures such as the second edge 1503 and the second guide edge 1504.

[0131] Reference Figure 6 As shown, an embodiment of the platform board of the present invention is manufactured using the platform board manufacturing method of the first aspect embodiment. The platform board has high structural strength, strong load-bearing capacity, and long service life. The platform board of this embodiment is processed from a first metal plate 1400 and a second metal plate 1500. A second annular wall 1502 is fitted onto the outside of the first annular wall 1402, forming a double-layer support structure, which improves the strength of the support structure. The support structure supports the first metal plate 1400 and the second metal plate 1500, thereby allowing the first metal plate 1400 and the second metal plate 1500 to join and form the support surface of the platform board, further improving the structural strength of the platform board. The first metal plate 1400 and the second metal plate 1500 are sheet metal parts, simplifying the processing steps, improving production efficiency, and reducing production costs. Furthermore, the first metal plate 1400 and the second metal plate 1500 are thin, strong, and lightweight, making the manufactured platform board easy for workers to handle and use. The metal material can also be easily recycled and reused, saving energy and protecting the environment.

[0132] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
