[0034] Please see Figures 1 to 4 , Figure 1This is a structural schematic diagram of an embodiment of the door panel provided in this application. Figure 2 This is an exploded structural diagram of a door panel embodiment provided in this application. Figure 3 yes Figure 1 A magnified schematic diagram of the structure at point A in the middle. Figure 4 This is a partially enlarged structural schematic diagram of one embodiment of the panel provided in this application.

[0035] This application provides a door panel 100. The door panel 100 includes a front panel 10, a cover plate 20, a filling layer 30, and a support layer. The cover plate 20 has a mounting cavity 101. The front panel 10 is fixedly connected to the cover plate 20 and covers the opening of the mounting cavity 101. The filling layer 30 is disposed within the mounting cavity 101. The support layer 40 is disposed within the mounting cavity 101 and is located at least between the front panel 10 and the filling layer 30. The support layer 40 is made of a metal plate.

[0036] Compared to wooden door panels in related technologies, this application provides a filling layer 30 and a metal support layer 40 between the panel 10 and the cover plate 20, leveraging the high strength of the metal plate to enhance the overall strength of the door panel 100. The support layer 40, made of metal, has a robust structure, strong resistance to bending and compression, providing strong support for the panel 10 and enhancing its strength, effectively resisting deformation caused by prolonged use and external impacts.

[0037] In some embodiments, the door panel 100 serves as a cabinet door for panel furniture. Specifically, the door panel 100 can serve as a cabinet door for furniture such as kitchen cabinets, wardrobes, and bathroom vanities.

[0038] The door panel 100 provided in this application embodiment includes, but is not limited to, cabinet doors as panel furniture.

[0039] In some embodiments, the panel 10, support layer 40, filler layer 30 and cover plate 20 are bonded to each other with adhesive (not shown).

[0040] For example, the adhesive is an epoxy resin adhesive or a reactive polyurethane hot melt adhesive (PUR hot melt adhesive).

[0041] The glue can also be made of other materials; there are no further restrictions here.

[0042] In some embodiments, panel 10 is a solid wood board, plywood, OSB board, or particleboard.

[0043] In other embodiments, panel 10 may also be a non-metallic plate of other materials.

[0044] In some embodiments, a decorative layer (not shown) is also provided on the side of the panel 10 away from the filling layer 30 to enhance the aesthetics of the panel 10 surface and strengthen the protection of the panel 10 surface.

[0045] Decorative layers include, but are not limited to, wood veneer layers, oil coating layers, printed wood grain layers, PVC film layers, PET film layers, melamine-impregnated paper layers, and UV lacquer layers.

[0046] For example, panel 10 is a solid wood board. The decorative layer may be an oil coating to enhance the natural wood grain texture of the solid wood and improve its durability and abrasion resistance, etc.

[0047] In some embodiments, the edge of panel 10 away from the filling layer 30 is provided with a chamfer 12 or a rounded corner to ensure a smooth feel and to reduce the impact of some unavoidable scratches on the joint of panel 10 during use.

[0048] For example, the edge of panel 10 away from the filling layer 30 is provided with a chamfer 12.

[0049] In some embodiments, the filler layer 30 is made of honeycomb aluminum. The cover plate 20 is made of stainless steel. The support layer 40 is made of stainless steel.

[0050] The filling layer 30 uses honeycomb aluminum, which helps to reduce the weight of the door panel 100, and also improves the strength and rigidity of the door panel 100. At the same time, it has good sound insulation and heat insulation performance.

[0051] The cover plate 20 is made of stainless steel, which has good advantages such as corrosion resistance, insect resistance, and deformation resistance.

[0052] When the door panel 100 serves as a cabinet door, it faces outwards, meaning the user sees the panel 10 from the outside. The cover plate 20 faces inwards. In this embodiment, the panel 10 is made of a non-metallic sheet, giving it a high aesthetic appeal, while the cover plate 20 is made of stainless steel, possessing high strength, moisture resistance, corrosion resistance, and environmental friendliness, making it suitable for long-term use. In other words, the door panel 100 provided in this embodiment combines the advantages of wooden and metal door panels in related technologies.

[0053] In some embodiments, the cover plate 20 includes a back plate 21 and a side plate 22 disposed on one side of the back plate 21 and facing the panel 10. The back plate 21 and the side plate 22 enclose a mounting cavity 101. The opening of the mounting cavity 101 faces the panel 10. A filling layer 30 and a support layer 40 are mounted in the mounting cavity 101 through the opening. The side plate 22 encloses at least a portion of the side of the panel 10.

[0054] The support layer 40 includes a substrate 41, which is located between the panel 10 and the filler layer 30. The surface of the substrate 41 away from the filler layer 30 and the side plate 22 form a mounting space 102, and the panel 10 is partially inserted into the mounting space 102.

[0055] The support layer 40 can be a planar structure or a non-planar structure.

[0056] For example, the portion of the support layer 40 located between the filler layer 30 and the panel 10 is a planar structure and is made of stainless steel plate. It has a sturdy structure, strong resistance to bending and compression, provides strong support for the flatness of the panel 10, and enhances the strength of the panel 10, effectively resisting deformation caused by long-term use and external impact.

[0057] The surface of the substrate 41 away from the filling layer 30 and the side plate 22 form an installation space 102. The panel 10 is partially inserted into the installation space 102 to provide space for better fit between the panel 10 and the substrate 41, and to facilitate the installation between the panel 10 and the cover plate 20. This can improve the component assembly efficiency in the production process, improve process efficiency, and reduce production costs.

[0058] In some embodiments, a mounting groove 11 is provided at one end of the panel 10 near the filler layer 30, the mounting groove 11 connecting the back side and the side side of the panel 10. A side plate 22 abuts against the bottom wall of the mounting groove 11 and is spaced apart from the side wall of the mounting groove 11. The mounting groove 11 is partially located within the mounting space 102. That is, the side plate 22 surrounds a portion of the side of the panel 10.

[0059] An installation groove 11 is provided at the end of the panel 10 near the filling layer 30 to facilitate the assembly between the panel 10 and the cover plate 20, which can improve the component assembly efficiency, improve process efficiency, and reduce production costs.

[0060] The side panel 22 is spaced apart from the side wall of the mounting groove 11 to provide adhesive space for subsequent fixing of the side panel 22 and the panel 10.

[0061] In some embodiments, the depth of the mounting groove 11 is 2.5 mm to 3.5 mm.

[0062] For example, the depth of the mounting groove 11 is 3 mm.

[0063] In some embodiments, the support layer 40 further includes a frame 42 disposed on one side of the substrate 41 and away from the panel 10, the frame 42 extending to the side of the filling layer 30 and covering at least a portion of the side of the filling layer 30.

[0064] Specifically, the frame 42 is disposed between the side of the filling layer 30 and the side plate 22 so that the support layer 40 covers the filling layer 30. The frame 42 not only increases the bonding area between the filling layer 30 and the support layer 40, but also increases the surface area of ​​the support layer 40, so as to cooperate with the side plate 22 to improve the overall support strength of the panel 10.

[0065] The frame 42 covers a portion of the side of the filling layer 30, that is, the frame 42 is spaced apart from the substrate 41; or, the frame 42 covers the entire side of the filling layer 30, that is, the frame 42 abuts against the substrate 41, and the filling layer 30 abuts against the substrate 41; or, the frame 42 covers the entire side of the filling layer 30 and extends beyond the filling layer 30 in the direction toward the substrate 41, that is, the frame 42 abuts against the substrate 41, and the filling layer 30 is spaced apart from the substrate 41. The support layer 40 and the filling layer 30 are bonded first, and then the cover plate 20 is bonded.

[0066] For example, the frame 42 covers the entire side of the filler layer 30, that is, the frame 42 abuts against the substrate 41, and the filler layer 30 abuts against the substrate 41.

[0067] In other embodiments, the support layer 40 further includes a limiting portion 43 located on one side of the substrate 41 and facing the panel 10. The limiting portion 43 is inserted into the mounting groove 11 and is located between the side wall of the mounting groove 11 and the side plate 22 to limit the side wall of the mounting groove 11.

[0068] Specifically, the panel 10 is partially inserted into the space formed between the limiting part 43 and the substrate 41 to limit the panel 10. At the same time, the design of the limiting part 43 can increase the bonding area between the panel 10 and the support layer 40, which can further improve the support of the panel 10.

[0069] Please see Figures 1 to 5 , Figure 5 This is a structural schematic diagram of another embodiment of the door panel provided in this application.

[0070] In some other embodiments, the support layer 40 further includes a frame 42 disposed on one side of the substrate 41 and away from the panel 10, and a limiting portion 43 disposed on one side of the substrate 41 and facing the panel 10. The frame 42 extends to the side of the filler layer 30 and covers at least a portion of the side of the filler layer 30. The limiting portion 43 is inserted into the mounting groove 11 and is located between the side wall of the mounting groove 11 and the side plate 22 to limit the side wall of the mounting groove 11. Referring to the above description, further details are omitted here.

[0071] Please see Figures 1 to 6 , Figure 6 This is a structural schematic diagram of another embodiment of the door panel provided in this application.

[0072] In some embodiments, the side panel 22 surrounds the side of the panel 10. That is, the side end of the panel 10 near the filler layer 30 is not provided with the mounting groove 11. The side panel 22 is located on the side of the panel 10 and covers at least a portion of the end face of the side of the panel 10.

[0073] For example, the side panel 22 covers the entire side of the panel 10. That is, the side panel 22 covers the entire end face of the panel 10 on the side to better cover the panel 10.

[0074] Taking the support layer 40, including the frame 42, as an example, the production process of the door panel 100 is as follows:

[0075] According to the design plan, the cover plate 20, the filling layer 30, the support layer 40 and the panel 10 are cut to standard sizes. The cover plate 20 and the support layer 40 need to be grooved and bent, and the panel 10 needs to be grooved and chamfered. After the above basic components are processed, the assembly process is carried out.

[0076] First, the filling layer 30, cover plate 20, and support layer 40 are laminated. Specifically, adhesive is applied between the cover plate 20, support layer 40, and filling layer 30, and a vacuum hot press is used to firmly laminate them together, ensuring a smooth, bubble-free surface and enhancing structural strength, forming a sandwich-like composite structure with the cover plate 20, support layer 40, and filling layer 30 sandwiched between them. Adhesive is then applied to the back of panel 10, and panel 10 is aligned and spliced ​​with the composite structure. Finally, the cover plate 20 undergoes surface treatments such as painting or powder coating, and panel 10 undergoes surface treatments such as wood oiling to highlight the natural wood grain texture and enhance the protection of panel 10's surface. The assembled door panel 100 is sturdy and durable, possessing high strength, moisture resistance, corrosion resistance, and environmental friendliness, making it suitable for long-term use.

[0077] The door panel 100 of this utility model has the following beneficial effects: 1. Wide range of applications: This new door panel 100 can be used as a door panel for panel furniture such as bathroom cabinets, kitchen cabinets, and wardrobes. At the same time, its excellent corrosion resistance and insect resistance properties allow it to meet both indoor and outdoor use environments; 2. Reduced after-sales costs: The cover plate 20 and support layer 40 of the door panel 100 are made of stainless steel. The high strength of stainless steel can effectively solve the common deformation problem of large wooden door panels, eliminating the need for straighteners and extending the product life.
