[0055] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are 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 therefore should not be understood as a limitation on the present invention.

[0057] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0058] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0059] Reference Figure 1As shown, a floor plate 1000 of 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. The floor plate 1000 of this embodiment realizes load-bearing through the support units 100, has a strong load-bearing capacity, and can be circulated and used in multiple links of logistics transportation.

[0060] Reference Figure 2 and Figure 3a As shown, a support unit 100 of an embodiment of the present invention can be used on a panel structure such as a platform plate, a box body, etc., to bear a load. The support unit 100 of this embodiment includes a first plate 110 and a second plate 120 that are spaced apart. The first plate 110 and the second plate 120 can be made of metal materials, such as sheet metal parts. The first plate 110 and the second plate 120 are processed by sheet metal parts, which makes the processing procedure of the support unit 100 simpler, and the manufactured support unit 100 has the characteristics of high structural strength and light weight. It is understandable 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 are made of metal, which can be easily recycled and reused, is environmentally friendly and saves resources.

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

[0062] Reference Figure 1 As shown, for example, when the support unit 100 is used for manufacturing a floor panel, the support unit 100 is made of galvanized sheet materials or electrolytic sheet materials to form the floor panel, which fully meets the use requirements of the floor panel, and the floor panel made of the galvanized sheet materials or electrolytic sheet materials generates very little waste after dismantling, and the recycling rate of the floor panel made of the dismantled galvanized sheet materials or electrolytic sheet materials is more than 80%, which meets the requirements of environmental protection performance.

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

[0064] The plurality of second annular walls 121 are arranged in one-to-one correspondence with the plurality of first annular walls 111, and the second annular walls 121 are sleeved on the outside of the first annular walls 111. The second annular walls 121 and the first annular walls 111 can be arranged to be tightly fitted, so that the first annular walls 111 and the second annular walls 121 fit together to form a stable support structure 130, and the support structure 130 is used to support the first plate 110 and the second plate 120. It should be noted that the tight fit connection can be understood as a connection mode in which there is no relative movement between the first annular wall 111 and the second annular wall 121, and the first annular wall 111 and the second annular wall 121 can be connected by interference fit or transition fit, or can be completely fitted or partially fitted. The first annular wall 111 and the second annular wall 121 can be tightly fitted by extrusion deformation, which is not specifically limited here.

[0065] The plurality of support structures 130 are hollow cylindrical structures. The support structures 130 are arranged at intervals between the first plate 110 and the second plate 120. The plurality of support structures 130 form 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 deformed by extrusion, and can effectively avoid the bending or twisting of the first plate 110 and the second plate 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 structure 130, and distributes the load to the plurality of support structures 130, thereby improving the bearing capacity of the support unit 100.

[0066] Moreover, the first annular wall 111 and the second annular wall 121 are tightly fitted to each other, so that the connection between the first plate 110 and the second plate 120 is more secure, thereby improving the connection stability of the first plate 110 and the second plate 120 .

[0067] 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, which 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.

[0068] It is understandable 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 an integrally formed structure; the first annular wall 111 can also be fixedly connected to the first plate 110 by welding, riveting, etc., which is 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.

[0069] Reference Figure 3a As shown, in some embodiments of the present invention, the upper end portion of the second annular wall 121 (i.e., the end away from the second plate 120) is extended outward to be provided with a second edge 122, and the second edge 122 can be formed by bending the second annular wall 121, or formed by integral processing of the second plate 120. The second edge 122 fits with the first plate 110, so that the first annular wall 111 and the second annular wall 121 fit more closely, the connection is more tight, and the structural strength of the support structure 130 is improved. 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 bear the load of the first plate 110 more stably, thereby improving the 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 internally sleeved into the second annular wall 121, thereby making the first plate 110 and the second plate 120 join more smoothly 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 between the first plate 110 and the first annular wall 111. The first guide edge 113 fits with the second edge 122, so that the first guide edge 113 can achieve a more stable connection with 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 structural stability of the support structure 130, thereby further improving the 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 an arc, and the first guide edge 113 with an arc structure can improve the connection strength between the first plate 110 and the first ring wall 111, and effectively reduce the stress concentration. It can be understood that the longitudinal section of the first guide edge 113 can be understood as a section formed by the plane where the axis of the first ring wall 111 is located cutting the first guide edge 113. The longitudinal section of the second edge 122 is an arc that matches the first guide edge 113, and the second edge 122 with an arc structure can improve the connection strength between the second ring wall 121, and effectively reduce the stress concentration. In addition, the second edge 122 has a better supporting effect on 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 section formed by the plane where the axis of the second ring wall 121 is located cutting the second edge 122.

[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. 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 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 the first annular wall 111 forms a through groove 114, which penetrates between the first plate 110 and the second plate 120, so that a plurality of holes are formed on the support unit 100. The design of the hole position can make the support unit 100 have a water removal function, so that the support unit 100 can be used in an outdoor environment, improve the service life, and facilitate the cleaning of the platform plate 1000, and is also conducive to the ventilation of the goods.

[0073] Reference Figure 3a As shown, it can be understood that the inner diameter of the end of the first annular wall 111 of this embodiment away from the first plate 110 is greater than the inner diameter of the end close 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, such as by expanding or expanding the hole, 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 end of the first annular wall 111 away from the first plate 110 is extruded 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 extruded, 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 slipping out of 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 stronger.

[0074] Reference Figure 3a 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 a section formed by the plane where the axis of the first annular wall 111 is located cutting the first annular wall 111. In this embodiment, by tilting the first annular wall 111, the first annular wall 111 and the second annular wall 121 form a tapered structure, which can prevent the second plate 120 from escaping from the first plate 110, and further improve the structural stability of the support unit 100. Moreover, the tilt angle ranges from 1 degree to 3 degrees. When the tilt angle is within the above parameter range, the processing difficulty is small, 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 makes the processing of the support unit 100 simpler and the load-bearing effect better. 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 the support unit 100 of this embodiment, the inner diameter range of the through groove 114 is 35mm to 45mm, and the distance range between the axes of adjacent through grooves 114 is 40mm to 60mm. When the above parameter range is met, 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 when bearing, reduce stress concentration, and thus improve the 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, and the cross-sectional profile of the through groove 114 is circular. Therefore, the first annular wall 111 and the second annular wall 121 are both annular columnar structures, which makes the processing and assembly of the first plate 110 and the second plate 120 more convenient, reduces the difficulty of processing and assembly, and improves production efficiency. Of course, the cross-sectional profile of the through groove 114 can also be a triangle, a quadrilateral, a hexagon, etc., that is, the cross-sectional profile of the first annular wall 111 and the second annular wall 121 is a triangle, a quadrilateral, a hexagon, etc. structure, which is not specifically limited here. The support unit 100 adopting the above structure also has the advantages of high structural strength and strong 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 the first plate 110. The first annular wall 111 is formed by directly stamping the first plate 110, which can simplify the processing steps, improve production efficiency, and reduce the use of metal materials, which can save costs and 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 formed by directly stamping the first plate 110, which can simplify the processing steps, improve production efficiency, and reduce the use of metal materials, which can save costs and reduce 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) is extended outward to be provided with a first edge 112, and the first edge 112 can be formed by bending the first annular wall 111. The first edge 112 is fitted with the second plate 120, and the first edge 112 is pressed against the second plate 120. The first edge 112 can be connected to the second plate 120 by pressing, or welded to the second plate 120, or riveted to the second plate 120, and the specific connection method is not specifically limited here. Thus, the first annular wall 111 and the second annular wall 121 are more fitted, the connection is more tightened, 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 improving the 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 between the second plate 120 and the second annular wall 121. The second guide edge 123 fits with the first edge 112, so that the second guide edge 123 can achieve a more stable connection with 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 a support structure 130, which can further improve the structural strength and structural stability of the support structure 130, thereby further improving the bearing capacity of the support unit 100.

[0080] The second guide edge 123 is formed with a slot 1231, and the first edge 112 is snapped into the slot 1231, which can make the connection between the first edge 112 and the second guide edge 123 more stable. The structure of the slot 1231 can be formed by pressing the first edge 112 onto the second guide edge 123, thereby squeezing the second guide edge 123, which is simpler and more convenient to process, and has a more stable structure. Of course, the structure of the slot 1231 can also be realized by other forms of processing 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, so that the lower end surface of the support unit 100 is a relatively smooth surface, thereby avoiding cutting hands when people carry it, or interfering with transportation equipment (such as a forklift) to cause an unstable 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, and a support structure 130 formed by a first annular wall 111 and a second annular wall 121 is arranged 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 cavity 140 is formed into a closed space through the support structure 130 to prevent foreign objects, such as water, from entering the cavity 140.

[0083] It should be noted that, in the embodiment of the present invention, the depth of the cavity 140 is in the range of 12 mm to 20 mm. Within the above range, the support structure 130 enables the support unit 100 to have sufficient compressive strength, and can ensure that the cavity 140 is not squeezed and deformed, thereby making the support unit 100 more durable.

The matching structure of the first folded edge 115 and the second folded edge 124 can seal the edge of the support unit 100, prevent foreign matter 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, and improve 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 commonly used connection structure on a sheet metal part, or a folded edge structure fixed by fasteners such as bolts, or a folded edge structure fixed by welding, riveting, etc., which is not specifically limited here.

[0085] Reference Figures 1 to 5b As shown, a floor plate 1000 of an embodiment of the present invention includes the support unit 100 of the above embodiment. Among them, the embodiment of the present invention adopts the support unit 100 of the first embodiment, and the support unit 100 is provided by setting a first plate 110 and a second plate 120 arranged at intervals, and the first plate 110 is provided with a plurality of first annular walls 111 correspondingly sleeved on the outer side of the plurality of second annular walls 121 provided on the second plate 120, and the first annular walls 111 and the second annular walls 121 are matched and connected, so that the first plate 110 and the second plate 120 are fastened and connected, and the stability of the connection between the first plate 110 and the second plate 120 is improved; the first annular walls 111 and the second annular walls 121 are connected to form a support structure 130 for supporting the first plate 110 and the second plate 120, and the support structure 130 is arranged at intervals between 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, so that the floor plate 1000 has the advantages of high structural strength and strong bearing capacity. A cavity is formed between the first plate 110 and the second plate 120 and in 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 floor plate 1000 adopts all the technical solutions of the support unit 100 of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, 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, and the pallet 200 is formed by one or more support units 100. The bottom of the pallet 200 is provided with a support foot 300, and the support foot 300 supports the pallet 200 and leaves the bottom surface, so as to facilitate the transportation of the platform 1000 by a transportation tool such as a forklift. The support foot 300 can be made of metal, wood or plastic. It is understandable that the support foot 300 can be fixedly connected to the first plate 110, and can also be fixedly connected to 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 provided at the outer periphery of the third through hole 116. The third annular wall 117 can be formed by stamping. The third annular wall 117 extends toward the second plate 120 and abuts against the second plate 120, so that the first plate 110 is supported on the second plate 120 through the third annular wall 117, and the third annular wall 117 seals the cavity 140, thereby preventing foreign matter 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 provided along 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 aperture of the third through hole 116 is larger than the aperture of the fourth through hole 125, so as to ensure 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 is a hollow structure with an open upper end, and the support leg 300 is sleeved on the fourth ring wall 126, which is more convenient to install and lighter in weight. The support leg 300 is a cone structure, and the outer diameter of the support leg 300 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 slabs 1000 can be nested with each other, so that the support plates 200 of adjacent platform slabs 1000 can be stacked, thereby greatly reducing the space required for storing the platform slabs 1000.

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

[0092] It can be understood that in some embodiments of the present invention, a mounting edge 330 is provided at one end of the peripheral wall 320 away from the bottom wall 310, and the mounting edge 330 abuts against the second plate 120, thereby further improving the connection stability between the supporting foot 300 and the second plate 120, and improving the installation efficiency of the supporting foot 300 and the second plate 120, so that the structure of the platform plate 1000 is more reliable.

[0093] Continue to refer to Figure 5b As shown, the bottom wall 310 is provided with a fifth through hole 340, and the fifth through hole 340 is connected with the third through hole 116, the fourth through hole 125 and the inner cavity of the supporting foot 300, so as to realize drainage between the contact surface from the first plate 110 to the supporting foot 300, avoid water accumulation in the supporting foot 300, and thus improve 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 manufactured in one piece, such as by stamping or injection molding, and has a more stable structure, simpler processing, lighter weight, and is easy to install and replace.

[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 supporting foot 300 is configured to allow the fork tines of a forklift to be inserted, thereby facilitating the forklift to transport the platform 1000, improving the efficiency of transportation and enhancing the safety of transportation.

[0096] Reference Figure 6 As shown, a manufacturing method of a floor slab according to an embodiment of the present invention is used to produce a floor slab made of metal. The floor slab made of metal has high structural strength and strong bearing capacity, and the metal material can be recycled, which is energy-saving and environmentally friendly. The floor slab according to the embodiment of the present invention includes the following steps:

[0097] S601: Provide a first metal plate 1400. The size of the first metal plate 1400 is selected according to the size of the support 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 understandable that the first metal plate 1400 of the embodiment of the present invention is a sheet metal part, which has high strength, light weight, and is easy to process.

[0098] S602: A plurality of first through holes 1401 are formed at intervals along the length direction and the width direction of the first metal plate 1400. Fig.14 As shown, it can be understood that the plurality of first through holes 1401 are arranged in an array or evenly distributed. The plurality of first through holes 1401 can be processed by punching or the like. For example, the plurality of first through holes 1401 are arranged in multiple rows along the length direction of the first metal plate 1400, and each row is arranged in multiple rows along the width direction of the first metal plate 1400, and the first through holes 1401 corresponding to two adjacent rows are arranged in a staggered manner.

[0099] S603: Press out the first annular wall 1402 along the positions of the plurality of first through holes 1401. Fig.14 and Fig.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 peripheral edge of the first through hole 1401. The first annular wall 1402 can be extended in a direction perpendicular to the first metal plate 1400, or can be extended in a direction toward the second metal plate 1500, forming a hollow cylindrical structure. It can be understood that after the first annular wall 1402 is pressed, the aperture formed by the first annular wall 1402 is larger than the aperture of the first through hole 1401 processed in step S602. The inner hole formed by the first annular wall 1402 is conducive to the drainage of the first metal plate 1400, and also increases the overall strength of the first metal plate 1400.

[0100] S604: Provide a second metal plate 1500. The size of the second metal plate 1500 is selected according to the size of the supporting surface of the platform plate. The thickness and material of the second metal plate 1500 are selected according to the load-bearing requirements of the platform plate. In order to improve production efficiency, the size of the second metal plate 1500 is substantially the same as that of the first metal plate 1400. Of course, the parameters of the second metal plate 1500 (such as size, thickness or material) may also be different from those of the first metal plate 1400, and may be specifically designed according to usage requirements. It can be understood that the second metal plate 1500 of the embodiment of the present invention adopts sheet metal, which has high strength, light weight and is easy to process.

[0101] S605: A plurality of second through holes 1501 are formed at intervals along the length direction and the width direction of the second metal plate 1500. Fig.14As shown, it can be understood that the plurality of second through holes 1501 are arranged in an array or are evenly distributed. The arrangement of the second through holes 1501 is the same as that of the first through holes 1401. The plurality of second through holes 1501 can be processed by punching or the like. For example, the plurality of second through holes 1501 are arranged in multiple rows along the length direction of the second metal plate 1500, and each row is arranged in multiple rows along the width direction of the second metal plate 1500, and the second through holes 1501 corresponding to two adjacent rows are arranged in a staggered manner.

[0102] S606: Press out the second annular walls 1502 along the positions of the plurality of second through holes 1501. Fig.14 and Fig.15 As shown, it can be 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 peripheral edge of the second through hole 1501. The second annular wall 1502 can be extended in a direction perpendicular to the second metal plate 1500, or can be extended in a direction toward the first metal plate 1400 to form a hollow cylindrical structure. It can be understood that after the second annular wall 1502 is pressed, the aperture formed by the second annular wall 1502 is larger than the aperture of the second through hole 1501 processed in step S605. The inner hole formed by the second annular wall 1502 is conducive to the 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 in mirror symmetry, and align the first annular wall 1402 and the second annular wall 1502. Fig.15 and Fig.16 As shown, it can be understood that the second metal plate 1500 processed with the second annular wall 1502 can be flipped upside down, so as to be placed in a mirror-symmetrical manner with the first metal plate 1400, and the second annular wall 1502 on the second metal plate 1500 is aligned one by one with the first annular wall 1402 on the first metal plate 1400, thereby improving the accuracy of the paired installation of the first metal plate 1400 and the second metal plate 1500 and reducing the difficulty of production and processing.

[0104] It should be noted that the processing steps of the first metal plate 1400 and the second metal plate 1500 are interchanged in sequence and are not specifically limited here.

[0105] S608: Join the first metal plate 1400 and the second metal plate 1500, so that the second annular wall 1502 is sleeved on the outside of the first annular wall 1402 and is tightly fitted with the first annular wall 1402. Fig.17 and Fig.18As shown, it can be understood that the press fit between the first annular wall 1402 and the second annular wall 1502 can be understood as a connection mode 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 connected by interference fit or transition fit, or can be completely fitted or partially fitted. The press fit between the first annular wall 1402 and the second annular wall 1502 can achieve a stable connection between the first metal plate 1400 and the second metal plate 1500, thereby improving the overall stability of the platform plate. Moreover, the first annular wall 1402 and the second annular wall 1502 are connected to form a supporting structure. The supporting structure may be a hollow cylindrical structure, which can support the first metal plate 1400 and the second metal plate 1500, so that the first metal plate 1400 and the second metal plate 1500 are joined to form a stable supporting surface of the platform board, thereby improving the structural strength of the platform board; the supporting structure adopts a structure in which the second annular wall 1502 is sleeved on the outer side of the first annular wall 1402, which can form a double-layer structure, thereby improving the strength of the supporting structure and further improving the bearing capacity of the platform board.

[0106] S609: Provide support feet. It is understandable that the support feet are generally made of metal. Moreover, in order to reduce the overall weight of the platform and facilitate personnel to carry it, the support feet are generally made of sheet metal. For example, the support feet can be stamped parts, that is, processed into a hollow structure, so as to effectively reduce the weight while meeting the structural strength requirements. In addition, the support feet can also be made of lightweight materials with a certain strength, such as plastic or wood.

[0107] S610: The support foot is fixedly connected to the second metal plate 1500. It is understandable that there are multiple support feet, and the specific number of the support feet is designed according to the load-bearing requirements of the platform board and the load-bearing capacity of a single support foot. For example, there are 9 support feet, 8 of which are arranged at intervals along the outer periphery of the support surface of the platform board, and the other one is arranged at the center of the support surface of the platform board.

[0108] The manufacturing method of the platform plate of the embodiment of the present invention is as follows: by processing the first ring wall 1402 on the first metal plate 1400 and the second ring wall 1502 on the second metal plate 1500, and the first metal plate 1400 and the second metal plate 1500 are joined in a mirror-symmetrical manner, so that the second ring wall 1502 is sleeved on the outer side of the first ring wall 1402 and is tightly connected with the first ring wall 1402, thereby realizing the processing of the metal platform plate, and the processing process is simple, the production cost is reduced, and the produced platform plate has high structural strength, strong 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: Bend the edge of the first annular wall 1402 outward to form a first edge 1403. The first edge 1403 is formed at one 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 supporting effect of the first metal plate 1400 and the second metal plate 1500. The first edge 1403 can limit the degree of freedom of the second annular wall 1502 in the axial direction, prevent the first metal plate 1400 and the second metal plate 1500 from detaching, further improve the stability of the connection between the first metal plate 1400 and the second metal plate 1500, and thus strengthen the structural strength of the platform plate.

[0111] S702: Press the first edge 1403 against the second metal plate 1500. The first edge 1403 can be connected to the second metal plate 1500 by pressing, or welded to the second metal plate 1500, or riveted to the second metal plate 1500. The specific connection method is not specifically limited here. The first edge 1403 can make the connection between the first metal plate 1400 and the second metal plate 1500 more stable, making the overall structure of the platform plate more stable.

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

[0113] S801: Press out the second annular walls 1502 along the positions of the plurality of 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 holes formed by the second annular walls 1502 are conducive to drainage of the second metal plate 1500, and also increase the overall strength of the second metal plate 1500, thereby improving the bending resistance of the second metal plate 1500.

[0114] S802: Process the connection between the second metal plate 1500 and the second annular wall 1502 to form a second guide edge 1504 that can fit with the first edge 1403. It is understandable that the second guide edge 1504 and the second annular wall 1502 can be formed by one-time processing or by step-by-step processing. The second guide edge 1504 fits with the first edge 1403, so that the connection between the second annular wall 1502 and the first annular wall 1402 is tighter, so that the force on the platform is more uniform and the load-bearing effect is better; and the first edge 1403 can better support the second annular wall 1502, thereby improving the structural strength of the platform. In addition, the first edge 1403 can further limit the freedom of the second annular wall 1502 in the axial direction through the second guide edge 1504, prevent the first metal plate 1400 and the second metal plate 1500 from detaching, and further improve the stability of the connection between the first metal plate 1400 and the second metal plate 1500.

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

[0116] S901: The first edge 1403 is squeezed toward the second annular wall 1502, so that the second annular wall 1502 forms a slot 1505 that accommodates at least part of the first edge 1403. It can be understood that the first edge 1403 is engaged with the slot 1505, so that the connection between the first edge 1403 and the second annular wall 1502 is more stable and reliable. Furthermore, the first edge 1403 is stably connected to the second annular wall 1502, so that the first annular wall 1402 and the second annular wall 1502 form a stable support structure, thereby making the overall structure of the platform plate more stable and having a stronger bearing capacity.

[0117] It should be noted that when the second guide edge 1504 that can fit with the first edge 1403 is processed at the connection between the second annular wall 1502 and the second metal plate 1500, the clamping groove 1505 is formed on the second guide edge 1504. Thus, the first edge 1403 can be better connected with the second guide edge 1504, and the stability of the connection between the first metal plate 1400 and the second metal plate 1500 is improved. In addition, the first edge 1403 can be flush with the surface of the second metal plate 1500, which improves the stability of the platform when carried by a forklift and the safety of use when carried by personnel, and reduces the safety risk of the platform during use.

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

[0119] S1001: Extrude at least a portion of the first annular wall 1402 outward to form a cross-sectional inner diameter of the first annular wall 1402 that gradually increases in a direction away from the first metal plate 1400. It is understandable that the first annular wall 1402 may be extruded outward by means of expansion or hole expansion, which is not specifically limited here. For example, the entire first annular wall 1402 may be extruded, or one end of the first annular wall 1402 away from the first metal plate 1400 may be extruded. After the first annular wall 1402 is extruded, the longitudinal section of the first annular wall 1402 is inclined relative to the axis of the first annular wall 1402, and the inclination angle range may be designed to be 1 to 3 degrees. The longitudinal section of the first annular wall 1402 here may be understood as a cross section formed by the plane where the axis of the first annular wall 1402 is located cutting the first annular wall 1402. Therefore, by squeezing the first annular wall 1402, the connection between the first annular wall 1402 and the second annular wall 1502 can be made more secure, and the first annular wall 1402 and the second annular wall 1502 form a tapered structure, which can prevent the second metal plate 1500 from slipping out of the first metal plate 1400, further improving the structural stability of the platform board, and making the structural strength of the platform board higher and the bearing capacity stronger.

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

[0121] S1101: Press out second annular walls 1502 along the positions of the plurality of 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 holes formed by the second annular walls 1502 are conducive to drainage of the second metal plate 1500, and also increase the overall strength of the second metal plate 1500, thereby improving the bending resistance of the second metal plate 1500.

[0122] S1102: The edge of the second ring wall 1502 is bent outward to form a second edge 1503. The second edge 1503 is formed at one end of the second ring wall 1502 away from the second metal plate 1500. The second edge 1503 and the second ring wall 1502 can be formed by one-time processing or by step-by-step processing. The second edge 1503 can support the first ring wall 1402 or the first metal plate 1400, thereby improving the supporting 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, and can guide the first ring wall 1402 to be inserted into the second ring wall 1502, so that the first metal plate 1400 and the second metal plate 1500 are joined more smoothly, thereby improving the assembly efficiency.

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

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

[0125] S1202: Process the connection between the first metal plate 1400 and the first annular wall 1402 to form a first guide edge 1404 that can fit with the second edge 1503. It is understandable that the first guide edge 1404 and the first annular wall 1402 can be formed by one-time processing or by step-by-step processing. The first guide edge 1404 fits with the second edge 1503, making the connection between the first annular wall 1402 and the second annular wall 1502 more secure, so that the force on the platform slab is more uniform and the load-bearing effect is better; and the second edge 1503 can better support the first annular wall 1402, thereby improving the structural strength of the platform slab.

[0126] Reference Fig.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 understandable that the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can be respectively processed into mutually matching folded edges to achieve a stable connection, or can be connected by fasteners such as bolts, which is not specifically limited here. The outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 are fixedly connected, which can prevent rainwater or foreign objects from entering the space between the first metal plate 1400 and the second metal plate 1500 during use, causing the platform plate to be corroded and damaged. For example, when the connection between the first metal plate 1400 and the second metal plate 1500 is achieved by using mutually matching folding edges, the folding edges can be processed before the step of joining 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 are connected synchronously during the process of connecting the first annular wall 1402 and the second annular wall 1502. The step of connecting the outer periphery of the first metal plate 1400 and the outer periphery of the second metal plate 1500 can also be designed before or after the step of connecting the first annular wall 1402 and the second annular wall 1502, which is not specifically limited here.

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

[0129] Reference Fig.15 As shown, it can be understood that the first through hole 1401 and the second through hole 1501 are both formed by punching, and 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 Fig.14 and Fig.15As shown, it can be understood that the first through hole 1401 and the second through hole 1501 are both round holes, which are more convenient to process.
