Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing panel technology, specifically a novel honeycomb aluminum sound-absorbing panel. Background Technology

[0002] Honeycomb aluminum acoustic panels, also known as aluminum honeycomb perforated acoustic panels, are a high-performance building material widely used in indoor environments with strict acoustic requirements, such as conference rooms, concert halls, theaters, schools, hospitals, and various public places. Honeycomb aluminum acoustic panels consist of two thin aluminum sheets and an aluminum honeycomb core layer in between. This unique construction method ensures high flatness of the panel even with a large area, while significantly reducing the weight of the panel and maintaining high strength and rigidity.

[0003] The utility model patent with announcement number CN205224316U discloses an aluminum honeycomb sound-absorbing panel, including a box body, an aluminum alloy plate, and an aluminum honeycomb core. By filling the aluminum honeycomb core with asbestos fibers, the asbestos fibers have a porous internal structure. Since the speed of sound propagation in air is less than that in solids, when sound waves pass through, friction is generated due to flow resistance, causing some of the sound energy to be absorbed by the fibers. In addition, a glass fiber mesh is embedded in a thin-layer chromatography silica gel plate. The glass fiber mesh also has a porous internal structure. Together with aluminum silicate cotton and wood fiber sound-absorbing panels, the transmission of sound waves is hindered, thereby achieving excellent sound insulation performance.

[0004] In the aforementioned panels, the materials are fixedly connected by adhesive bonding. Although this gives the panel a strong sense of unity, it also makes the components almost separable. When one part is damaged or fails, the entire composite often needs to be discarded, which easily leads to waste of resources and high usage costs. Therefore, in order to address the above problems, a new type of honeycomb aluminum sound-absorbing panel is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a novel honeycomb aluminum sound-absorbing panel. This sound-absorbing panel achieves sound absorption through a sound-absorbing panel assembly. It is composed of a front baffle, a honeycomb panel, and a sound-absorbing panel, and has a good sound absorption effect. Furthermore, a sound-absorbing cavity is formed between the honeycomb panel and the sound-absorbing panel, which further improves the sound absorption effect. In particular, the above three panels are connected as a whole by side mounting frame bolts, thus having the characteristic of being detachable and separable. When any part is damaged or fails, it can be easily disassembled and replaced, which can improve the recyclability of each component and reduce the cost of use. This solves the technical problem in the prior art where the various parts of the sound-absorbing panel are often glued together. When one part is damaged or fails, the whole panel needs to be replaced, which easily leads to waste of resources and high cost of use.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A novel honeycomb aluminum sound-absorbing panel includes a side mounting frame in which a sound-absorbing panel assembly is fixedly mounted by connecting bolts; a closed frame located at the upper and lower ends of the sound-absorbing panel assembly and fixedly connected to the side mounting frame by connecting bolts; and a sound-insulating back panel installed on the back of the sound-absorbing panel assembly. All the above structures are connected as a whole by snap-fit ​​or bolt connection, thus possessing excellent detachable and separable characteristics. When any part is damaged or fails, it can be easily disassembled and replaced, enabling the components to be recycled and reducing usage costs.

[0008] The sound-absorbing panel assembly comprises three layers of material, arranged from front to back as a front baffle, a honeycomb panel, and a sound-absorbing panel. The front baffle has rectangular holes arranged in an array, and the honeycomb panel has honeycomb holes arranged in an array. The holes in the front baffle facilitate the entry of sound waves into the honeycomb holes, and the closed cells of the honeycomb holes effectively absorb and disperse sound wave energy. The sound-absorbing panel is made of melamine board, which has good sound absorption performance and can further reduce echoes and noise. Furthermore, the honeycomb panel and the sound-absorbing panel enclose a sound-absorbing cavity, which can further enhance the absorption and dissipation of sound and further improve the sound absorption effect.

[0009] In one possible implementation, a first connecting angle is fixedly provided at each of the four corners of the front baffle, and a second connecting angle is fixedly provided at each of the four corners of the honeycomb panel. Since both the front baffle and the honeycomb panel are porous structures, the first and second connecting angles can ensure the stability of the connection. At the same time, mounting holes are provided at the four corners of the front baffle, the honeycomb panel and the sound-absorbing panel, which provide the necessary structural foundation for the connection and fixing of the connecting bolts.

[0010] In one possible implementation, the side mounting frame includes a frame plate with end-closing plates fixedly installed at both its upper and lower ends. A first partition plate and a first C-shaped partition plate are fixedly installed inside the frame plate. The first partition plate and the first C-shaped partition plate divide the internal space of the frame plate into three mounting grooves, which are used to snap the front baffle, honeycomb panel and sound-absorbing panel respectively. The above structure can complete the snap-fit ​​and fixation of the front baffle, honeycomb panel and sound-absorbing panel, ensuring the stability of the installation, and at the same time can provide stable support to prevent the three-layer panel from deforming during use.

[0011] In one possible implementation, a plurality of support cylinders are fixedly installed inside the first C-shaped partition, wherein through holes with a size larger than that of the connecting bolts are opened along the axis, and the connecting bolts pass through the support cylinders during installation. The support cylinders can support the first C-shaped partition and prevent it from bending and deforming under the clamping force of the connecting bolts.

[0012] In one possible implementation, the enclosed frame includes a sealing plate with overlapping folded plates fixedly disposed at both ends. The frame plate has overlapping feet at both ends, and the overlapping feet are fixedly connected to the overlapping folded plates by connecting bolts. The above structural form can realize the fixed connection between the enclosed frame and the side mounting frame to ensure the stability of the overall structure.

[0013] In one possible implementation, a second C-shaped partition and a second dividing plate are fixedly provided inside the sealing plate. The two partitions divide the space inside the sealing plate into three mounting grooves, which are used to snap the front baffle, honeycomb panel and sound-absorbing panel respectively. The above structure can complete the snap-fit ​​and fixation of the front baffle, honeycomb panel and sound-absorbing panel, ensuring the stability of the installation, and at the same time can provide stable support to prevent the three-layer panel from deforming during use.

[0014] In one possible implementation, the sound insulation back panel includes a back panel body with snap-fit ​​edges fixedly provided on its inner side. After the back panel body is bolted to the side mounting frame, the snap-fit ​​edges fit into the side mounting frame and the closed frame. The snap-fit ​​edges can realize the snap-fit ​​function between the back panel body and the side mounting frame and the closed frame, thereby improving the stability of the outer frame of the panel.

[0015] In one possible implementation, a raised strip structure is fixedly provided on the inner wall of both sides of the first C-shaped partition, which extends along the length of the first C-shaped partition. This raised strip structure can improve the bending resistance of the first C-shaped partition and prevent it from bending and deforming during use, thus losing its locking and limiting function for the honeycomb panel and the sound-absorbing panel.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] This sound-absorbing panel achieves sound absorption through a combination of sound-absorbing panels. It is composed of a front baffle, a honeycomb panel, and a sound-absorbing panel, which has a good sound absorption effect. Furthermore, the honeycomb panel and the sound-absorbing panel form a sound-absorbing cavity, which further improves the sound absorption effect. In particular, the three panels are connected as a whole by side mounting frame bolts, thus having the characteristic of being detachable and separable. When any part is damaged or fails, it can be easily disassembled and replaced, which can improve the recyclability of each component and reduce the cost of use. Attached Figure Description

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 3 As shown, this embodiment provides a novel honeycomb aluminum sound-absorbing panel, including a side mounting frame 1, in which a sound-absorbing panel assembly 2 is fixedly installed by connecting bolts 5; a closed frame 3, which is located at the upper and lower ends of the sound-absorbing panel assembly 2 and is fixedly connected to the side mounting frame 1 by connecting bolts 5; and a sound insulation back panel 4, which is installed on the back of the sound-absorbing panel assembly 2. All the above structures are connected as a whole by snap-fit ​​or bolt connection, thus having excellent detachable and separable characteristics. When any part is damaged or fails, it can be easily disassembled and replaced, enabling the components to be recycled and reducing the cost of use.

[0028] The sound-absorbing panel assembly 2 comprises three layers of panels, which are arranged from front to back as a front baffle 21, a honeycomb panel 22, and a sound-absorbing panel 23. The front baffle 21 has rectangular holes arranged in an array, and the honeycomb panel 22 has honeycomb holes arranged in an array. The holes in the front baffle 21 facilitate the entry of sound waves into the honeycomb holes. The closed cells of the honeycomb holes can effectively absorb and disperse sound wave energy. The sound-absorbing panel 23 is made of melamine board, which has good sound absorption performance and can further reduce echo and noise. The honeycomb panel 22 and the sound-absorbing panel 23 form a sound-absorbing cavity. This structure can further enhance the absorption and dissipation of sound and further improve the sound absorption effect.

[0029] like Figure 3 As shown, a first connecting angle 211 is fixedly provided at each of the four corners of the front baffle 21, and a second connecting angle 221 is fixedly provided at each of the four corners of the honeycomb panel 22. Since both the front baffle 21 and the honeycomb panel 22 are porous structures, the first connecting angle 211 and the second connecting angle 221 can ensure the stability of the connection. At the same time, mounting holes 24 are provided at the four corners of the front baffle 21, the honeycomb panel 22 and the sound-absorbing panel 23. These holes provide the necessary structural foundation for the connection and fixing of the connecting bolts 5.

[0030] like Figure 4 As shown, the side mounting frame 1 includes a frame plate 11, with end-closing plates 12 fixedly installed at both its upper and lower ends. A first partition plate 13 and a first C-shaped partition plate 14 are fixedly installed inside the frame plate 11. The first partition plate 13 and the first C-shaped partition plate 14 divide the internal space of the frame plate 11 into three mounting grooves, which are used to snap the front baffle 21, the honeycomb panel 22, and the sound-absorbing panel 23, respectively. The above structure can complete the snap-fit ​​and fixation of the front baffle 21, the honeycomb panel 22, and the sound-absorbing panel 23, ensuring the stability of the installation, and at the same time, it can provide stable support to prevent the three-layer panel from deforming during use.

[0031] The first C-shaped partition 14 is fixedly provided with several support cylinders 15, which have through holes along the axis with a size larger than that of the connecting bolts 5. The connecting bolts 5 pass through the support cylinders 15 during installation. The support cylinders 15 can support the first C-shaped partition 14 and prevent it from bending and deforming under the clamping force of the connecting bolts 5.

[0032] like Figure 5 - Figure 6As shown, the enclosed frame 3 includes a sealing plate 31, with overlapping folded plates 32 fixedly installed at both ends. The frame plate 11 has overlapping feet 16 at both ends, and the overlapping feet 16 are fixedly connected to the overlapping folded plates 32 by connecting bolts 5. The above structure can realize the fixed connection between the enclosed frame 3 and the side mounting frame 1 to ensure the stability of the overall structure. In addition, a second C-shaped partition 33 and a second partition plate 34 are fixedly installed inside the sealing plate 31. The two partitions divide the space inside the sealing plate 31 into three mounting grooves, which are used to snap the front baffle 21, the honeycomb panel 22 and the sound-absorbing panel 23 respectively. The above structure can complete the snap-fit ​​and fixation of the front baffle 21, the honeycomb panel 22 and the sound-absorbing panel 23, ensuring the stability of the installation, and at the same time can provide stable support to prevent the three-layer panel from deforming during use.

[0033] like Figure 5 As shown, the sound insulation back panel 4 includes a back panel body 41, and a snap-fit ​​rib 42 is fixedly provided on its inner side. After the back panel body 41 is bolted to the side mounting frame 1, the snap-fit ​​rib 42 fits with the side mounting frame 1 and the closed frame 3. The snap-fit ​​rib 42 can realize the snap-fit ​​function between the back panel body 41 and the side mounting frame 1 and the closed frame 3, thereby improving the stability of the outer frame of the panel.

[0034] like Figure 4 As shown, both sides of the first C-shaped partition 14 are fixedly provided with a convex strip structure, which extends along the length of the first C-shaped partition 14. The convex strip structure can improve the bending resistance of the first C-shaped partition 14 and prevent it from bending and deforming during use, thus losing its snap-fit ​​and limiting function for the honeycomb panel 22 and the sound-absorbing panel 23.

[0035] The working principle and usage process of this utility model:

[0036] The sound-absorbing panel achieves sound absorption through the sound-absorbing panel assembly 2, which is composed of a front baffle 21, a honeycomb panel 22, and a sound-absorbing panel 23. It has a good sound absorption effect. The holes in the front baffle 21 allow sound waves to enter the honeycomb cells, and the closed cells of the honeycomb cells can effectively absorb and disperse sound wave energy. The sound-absorbing panel 23 is made of melamine board, which has good sound absorption performance and can further reduce echoes and noise. Furthermore, the honeycomb panel 22 and the sound-absorbing panel 23 form a sound-absorbing cavity. This structure can further enhance the absorption and dissipation of sound and further improve the sound absorption effect.

[0037] Specifically, the three panels are bolted together as a whole by the side mounting frame 1, thus possessing the characteristic of being detachable and separable. When any part is damaged or fails, it can be easily disassembled and replaced, which can improve the recyclability of each component and reduce the cost of use. The side mounting frame 1 includes a frame plate 11, with end sealing plates 12 fixedly installed at both the upper and lower ends. A first partition plate 13 and a first C-shaped partition plate 14 are fixedly installed inside the frame plate 11, dividing the internal space of the frame plate 11 into three mounting grooves, which are used to clamp the front baffle 21, the honeycomb panel 22, and the sound-absorbing panel 23, respectively, to ensure the stability of the installation and to provide stable support, preventing the three-layer panel from deforming during use. Similarly, the second C-shaped partition plate 33 and the second partition plate 34 divide the internal space of the sealing plate 31 into three mounting grooves, which are used to clamp the front baffle 21, the honeycomb panel 22, and the sound-absorbing panel 23, respectively, to ensure the stability of the installation and to provide stable support, preventing the three-layer panel from deforming during use.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
