Description

Technical Field

[0001] The utility model relates to the field of decorative plate structures, in particular to a sound-absorbing three-dimensional perforated metal decorative plate. Background Art

[0002] In the field of architectural decorative materials, perforated decorative panels are widely used in various applications, including interior and exterior wall decoration, acoustic treatment, and ventilation systems, due to their unique visual effects and breathability. However, most common perforated decorative panels on the market are flat. While this meets basic decorative needs to a certain extent, traditional flat perforated panels often fail to achieve ideal sound insulation in places where noise transmission needs to be controlled, such as conference rooms, recording studios, and libraries, limiting their application.

[0003] At the same time, due to the limitations of the perforation process, flat panels are prone to deformation during the perforation process, resulting in poor flatness and unevenness, which in turn affects the decorative effect. Furthermore, due to their heavy weight and lack of an effective support structure, they are prone to sagging as the size of the panels increases, which not only affects the decorative effect but also increases the difficulty and cost of installation. To overcome this problem, existing technologies typically increase the thickness of the material to enhance the panel's resistance to deformation, but this increases material consumption and costs.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1:

[0021] refer to Figure 1-2 A sound-absorbing three-dimensional perforated metal decorative panel includes a panel body 1. The panel body 1 can be made of corrosion-resistant, high-strength metal materials such as stainless steel, aluminum alloy or galvanized steel plate to ensure that the decorative panel can maintain stable physical properties and beautiful appearance in harsh environments.

[0022] The plate body 1 includes a plurality of rising areas 11 and a plurality of descending areas 12. The plurality of rising areas 11 and the plurality of descending areas 12 are alternately connected. A descending area 12 is provided between two rising areas 11 to form a unique three-dimensional surface. The plate body 1 is provided with a plurality of perforations 13, so that the plate body 1 has good ventilation and air permeability. The plurality of perforations 13 are evenly spaced on the plate body 1. The rising areas 11 and the descending areas 12 make the plate body 1 present an uneven structure on both sides. When there is a slight unevenness on the plate surface caused by the perforations 13 on the plate body 1, the plurality of rising areas 11 and the plurality of descending areas 12 are uneven. The superposition will create a visual illusion, thereby covering up the unevenness of the board surface and ensuring the harmony and unity of the overall visual effect; at the same time, when the sound waves are transmitted to the board body 1, they will be dispersed by the uneven structure, so that the sound waves pass through the rising area 11 and the falling area 12 at different times, and the sound waves are effectively attenuated, thereby having a sound-absorbing and noise-reducing effect; at the same time, the uneven structure formed by the rising area 11 and the falling area 12, plus the multiple perforations 13 make the board body 1 semi-transparent, thereby having a semi-transparent visual effect, which can provide rich layering and artistic appreciation, and enhance its decorative function.

[0023] In some embodiments, both the rising area 11 and the falling area 12 can be crater-shaped, and the plate body 1 can be calendered into a double-sided concave and convex crater shape by the upper and lower calendering die rollers. The geometric shape (including but not limited to circular, rectangular, triangular, star-shaped, elliptical, etc.), size, depth and arrangement of the calendering roller craters can be arbitrarily designed according to customer needs; the interconnections between multiple rising areas 11 and multiple falling areas 12 form multiple interconnected and mutually supporting reinforcing rib structures on the top and bottom surfaces of the plate body 1, which can enhance the rigidity and strength of the plate body 1 itself, making the plate more stable and reliable when subjected to external force, thereby avoiding the phenomenon of sagging when the plate surface size increases, and realizing lightweight design.

[0024] Because the entire panel surface is concave and convex, even slight unevenness is invisible. The numerous craters formed on the surface not only effectively attenuate sound waves, providing a sound-absorbing and noise-reducing effect, but also provide light-shielding, ventilation, and a semi-transparent appearance. The overall visual effect is rich in three-dimensionality and highly aesthetic. Perforations 13 are coaxially located at the centers of rising area 11 and descending area 12. The geometric shape (including but not limited to circular, rectangular, triangular, star-shaped, and elliptical), aperture size, spacing, and arrangement of perforations 13 can be flexibly adjusted to meet diverse customer design requirements.

[0025] In some embodiments, the perforations 13 may be circular holes, the center distance between two adjacent perforations 13 may be 5 mm, and the diameter of the perforations 13 may be 2 mm, which helps to achieve good air permeability and sound-absorbing effects.

[0026] In some embodiments, a paint layer is provided on the surface of the board 1, which can be sprayed with paint. This paint layer can be provided on one side or both sides of the board 1, and different colors can be customized according to customer needs to meet diverse decorative styles and environmental adaptability requirements.

[0027] Specifically, the paint layer not only significantly enhances the decorative effect of the board, adding a touch of bright color to the architectural decoration through its rich colors and textures; at the same time, it acts as an effective protective barrier, effectively isolating the metal substrate from erosion by external environmental factors, thereby preventing the metal sheet from corroding and rusting, and extending the service life of the product.

[0028] In some embodiments, the thickness of the plate body 1 is 0.5 mm, achieving a lightweight design while ensuring sufficient strength.

[0029] The specific working principle is as follows:

[0030] When sound waves propagate from one side of the plate 1 to the other, they will be dispersed by the uneven structure of the surface of the plate 1, and thus pass through the rising area 11 and the falling area 12 respectively. The crater-shaped design of the rising area 11 and the falling area 12 increases the complexity of the sound wave propagation path. When the sound waves contact these areas, they will be reflected and refracted multiple times, consuming sound energy. In particular, when the rising area 11 and the falling area 12 are set at an angle, the propagation direction of the sound waves will be changed, and part of the sound waves will be reflected back to the direction of the sound source or scattered in other directions, thereby achieving the attenuation of the sound waves. At the same time, the aluminum alloy material of the plate 1 itself also has a certain absorption effect on sound waves. When the sound waves propagate in the plate 1, part of the sound energy will be absorbed by the material and converted into heat energy or other forms of energy dissipation.

[0031] After the sound waves passing through the plate 1 converge, due to the inconsistency of propagation direction, magnitude and phase, their energy will be partially offset when merging, thereby further attenuating the sound waves, thereby realizing the sound insulation and noise reduction function of the plate 1.

[0032] Example 2:

[0033] This embodiment differs from embodiment 1 in that:

[0034] The rising area 11 and the descending area 12 are both long strips, and are provided with a plurality of perforations 13 along their length directions. The rising area 11 and the descending area 12 are tilted and form an angle with the horizontal plane, which can be 30°-60°, preferably 45°.

[0035] The long strip-shaped rising area 11 and descending area 12 can reduce the processing difficulty of the plate body 1, and at the same time, the multiple perforations 13 on the plate body 1 can be arranged at different heights, positions, and directions, thereby forming a disordered arrangement of the perforations 13. When the sound waves pass through the plate body 1, they will be transmitted from different heights, positions, and directions, further attenuating the sound waves.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
