[0001] The present application relates to the technical field of minimalist doors, in particular to a sound insulation structure of a sound insulation minimalist complete door. BACKGROUND
[0002] A minimalist door is a kind of door product with simple design and modern style. It usually adopts simple lines and materials, and pursues a simple and light appearance effect, which meets the aesthetic needs of modern urban life. Minimalist doors are widely used in interior decoration, adding modernity and minimalist aesthetics to the space.
[0003] The characteristics of minimalist doors include: simple design: minimalist doors usually adopt a simple design style, avoiding excessive decoration and complicated elements, and showing a simple and clean appearance. Lightweight material: minimalist doors often use lightweight materials such as aluminum alloy and glass, making the overall door look light and agile. Strong sense of space: minimalist door design focuses on the sense of space and transparency, effectively increasing the brightness and openness of indoor space. Modern aesthetics: minimalist doors meet the aesthetic trends of modern urban life, and the simple and elegant appearance design is compatible with modern interior decoration style. In summary, as a modern and minimalist door product, minimalist doors are suitable for various indoor environments, adding modernity and minimalist aesthetics to the space, and are favored by many consumers.
[0004] Currently, minimalist doors usually use single-layer glass or solid wood veneer, which is different from the double-sided thickness of traditional solid wood doors, so the sound insulation effect is not as good as that of traditional doors. However, traditional solid wood doors are heavy, and with long-term use, they are prone to deformation and have weak resistance to deformation. SUMMARY
[0005] To solve the above technical problems, the present application provides a sound insulation structure of a sound insulation minimalist complete door, which comprises a sound insulation structure body, a first layer of steel plate, a second layer of steel plate and a third layer of steel plate are arranged inside the sound insulation structure body, a first core layer is arranged between the first layer of steel plate and the second layer of steel plate, a second core layer and a third core layer are arranged between the second layer of steel plate and the third layer of steel plate, an isolation layer is arranged between the second core layer and the third core layer, and the third core layer is made of aluminum honeycomb core and foamed plastic semi-filling.
[0006] Preferably, the thickness of the first layer of steel plate and the third layer of steel plate is different.
[0007] Preferably, the thickness of the first layer of steel plate is 0.2-5mm.
[0008] Preferably, the first core layer adopts an aluminum honeycomb core with a specification of 6*0.04mm-15*0.04mm (where 6 and 15 are the side lengths of the hexagon).
[0009] Preferably, the thickness of the first core layer is 5-40 mm.
[0010] Preferably, the thickness of the second steel plate is different from that of the first steel plate and the third steel plate.
[0011] Preferably, the thickness of the second layer of steel plate is 0.2-5 mm.
[0012] Preferably, the second core layer adopts an aluminum honeycomb core with a specification of 10*0.04mm to 20*0.04mm (wherein 10 and 20 are the side lengths of the hexagon).
[0013] Preferably, the thickness of the second core layer is 8-35 mm.
[0014] A minimalist door with a sound insulation structure using a sound insulation minimalist door set includes a door frame profile, a decorative panel and the above-mentioned sound insulation structure body. Two decorative panels are provided. The sound insulation structure body is arranged between the two decorative panels. The two decorative panels are fixed into an integrated structure through the door frame profile.
[0015] The technical effects and advantages of the present invention are as follows:
[0016] 1. In the present invention, the sound insulation structure is designed with multiple layers of steel plates and half of the core layer filled. Multiple core layers are placed in the multiple layers of steel plates, which supports the core layers. The overall structural strength and impact strength are high, the deformation resistance is strong, and the sound insulation effect is good and the weight is light.
[0017] 2. In the present invention, the third core layer is made of an aluminum honeycomb core and semi-filled with foamed plastic. The semi-filled material effectively disrupts the linear (downstream) propagation of sound waves in the honeycomb cavity, creating a turbulent flow within the cavity. This reduces energy consumption during sound wave propagation, reduces propagation out of the cavity, and thus increases sound insulation. It also enhances thermal insulation performance, protecting the sound insulation structure from temperature fluctuations.
[0018] 3. In the present invention, after the middle of the cavity is half-filled with polyurethane foam plastic, the combination of different sizes of the internal cavity, different wall thicknesses of the steel plate and the filler can effectively block the propagation of sounds of different wavelengths and frequencies through the filler.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.
[0023] See also Figure 1 In this embodiment, a sound insulation structure of a sound insulation minimalist door set is provided. A first steel plate 11, a second steel plate 13 and a third steel plate 17 are arranged in the sound insulation structure body 1. A first core layer 12 is arranged between the first steel plate 11 and the second steel plate 13, a second core layer 14 and a third core layer 16 are arranged between the second steel plate 13 and the third steel plate 17, and an isolation layer 15 is arranged between the second core layer 14 and the third core layer 16.
[0024] This sound insulation structure is designed with multiple layers of steel plates and multiple core layers filled in. Multiple core layers are placed inside the multiple layers of steel plates to support the core layers. The overall structural strength and impact strength are high, the deformation resistance is strong, and the sound insulation effect is good and the weight is light.
[0025] In this embodiment, the thickness of the first layer of steel plate 11 is different from that of the third layer of steel plate 17. The thickness of the first layer of steel plate 11 is 0.2-5 mm. Preferably, the first layer of steel plate 11 is a galvanized steel plate with a thickness of 0.8 mm. The galvanized steel plate is a steel plate that has been hot-dip galvanized and its surface is covered with a layer of zinc metal. By forming a zinc-iron alloy layer on the surface of the steel plate, the corrosion resistance and service life of the steel are effectively improved, thereby improving the service life of the sound insulation structure body 1.
[0026] In this embodiment, the first core layer 12 adopts an aluminum honeycomb core with a specification of 6*0.1mm and a thickness of 5-40mm. Preferably, the thickness of the first core layer 12 is 15mm. The aluminum honeycomb core is a material composed of aluminum foil arranged in a honeycomb shape. As a high-performance composite material, the multi-layer aluminum honeycomb core has significant advantages in lightweight, strength and sound absorption performance.
[0027] In this embodiment, the thickness of the second steel plate 13 is different from that of the first steel plate 11 and the third steel plate 17. The thickness of the second steel plate 13 is 0.2-5 mm. Preferably, the second steel plate 13 is a galvanized steel plate with a thickness of 0.3 mm. The second steel plate 13 is a galvanized steel plate with a thickness smaller than that of the first steel plate 11 and the third steel plate 17. The first core layer 12 and the second core layer 14 are fixed to the two end surfaces of the second steel plate 13 by spot welding or gluing, which improves the stability of the first core layer 12 and the second core layer 14 while reducing the weight of the sound insulation structure body 1.
[0028] In this embodiment, the second core layer 14 adopts an aluminum honeycomb core with a specification of 10*0.04mm and a thickness of 8-35mm. Preferably, the thickness of the second core layer 14 is 20mm. The density of the second core layer 14 is smaller than that of the first core layer 12, further reducing the weight of the sound insulation structure body 1.
[0029] In this embodiment, the isolation layer 15 is an aluminum foil layer with a thickness of 0.02-1 mm. The aluminum foil layer refers to a material made of stacked layers of aluminum sheets. The aluminum foil layer is light, soft, and has good sound insulation performance.
[0030] In this embodiment, the third core layer 16 is made of an aluminum honeycomb core and a foamed plastic half-filler. The specification of the aluminum honeycomb core used is 10*0.04mm. The thickness of the third core layer 16 is 1 / 5-1 / 2 of the thickness of the second core layer 14. The foamed plastic half-filler is a polyurethane foamed plastic filler, which has the following advantages:
[0031] Buffer protection: The filling material can absorb energy when the sound insulation structure body 1 is subjected to external impact, reducing the impact of the impact on the product, thereby protecting the product from damage;
[0032] Thermal insulation: It has good thermal insulation performance and can protect the sound insulation structure body 1 from the influence of temperature changes.
[0033] In this embodiment, the thickness of the third layer of steel plate 17 is 0.2-5 mm. Preferably, the third layer of steel plate 17 is a galvanized steel plate with a thickness of 0.5 mm. The third layer of steel plate 17 is spot welded or glued to the third core layer 16 to protect the third core layer 16. The overall structural strength and impact resistance are high, and the deformation resistance is strong.
[0034] In another embodiment, see Figure 2 As shown, a minimalist door with a sound insulation structure using a sound insulation minimalist door set is provided. The minimalist door includes a door frame profile 2 and a decorative panel 3. Two decorative panels 3 are provided. The sound insulation structure body 1 is provided between the two decorative panels 3. The two decorative panels 3 are fixed into an integrated structure through the door frame profile 2.
[0035] This minimalist door is placed in the glue-pressed sound insulation door body in turn with steel plate and aluminum honeycomb core, after which the large-cavity aluminum honeycomb core is placed, the pre-mixed foamed plastic is injected (the amount of foaming is weighed and injected under the condition of calculating and controlling the amount of foaming to ensure that the height direction is half-filled after foaming), and then the following are placed in turn: Figure 1 The other materials shown have an internal cavity with acoustic structural characteristics. After the middle of the cavity is filled with polyurethane foam plastic, the different sizes of the internal cavity, the different wall thicknesses of the steel plate and the combination of fillers can effectively block the propagation of sounds of different wavelengths and frequencies through the filler.
