Description

Technical Field

[0001] This application relates to the field of integrated wall panel technology, specifically to a noise-reducing bamboo and wood fiber integrated wall panel. Background Technology

[0002] Integrated wall panels are a type of modular interior decoration material, typically composed of a three-layer structure: a substrate layer, a decorative layer, and a protective layer. Depending on the material of the substrate layer, they can be categorized into various types, such as bamboo-wood fiber integrated wall panels, aluminum alloy integrated wall panels, and stone-plastic integrated wall panels. In existing technologies, to improve the noise reduction performance of bamboo-wood fiber integrated wall panels, sound-absorbing materials are usually added between the substrate layer and the decorative layer, between the decorative layer and the protective layer, or on the outside of the protective layer. However, the noise reduction performance of the sound-absorbing materials themselves is limited. If the ambient noise is high, multiple layers of sound-absorbing materials are needed to achieve a noise reduction effect, increasing the overall thickness. Therefore, a noise-reducing bamboo-wood fiber integrated wall panel is proposed. Utility Model Content

[0003] The purpose of this application is to address the technical problem that sound-absorbing materials are usually added between the substrate layer and the decorative layer, between the decorative layer and the protective layer, or on the outside of the protective layer. However, the noise reduction performance of the sound-absorbing materials themselves is limited. If the environmental noise is high, multiple layers of sound-absorbing materials need to be stacked to achieve the noise reduction effect, which increases the overall thickness. This application provides a noise-reducing bamboo and wood fiber integrated wall panel.

[0004] To achieve the above objectives, this application specifically adopts the following technical solution:

[0005] A noise-reducing bamboo-wood fiber integrated wall panel includes a substrate layer, a decorative layer, and a protective layer. A noise-reducing layer is disposed between the substrate layer and the decorative layer. The noise-reducing layer has multiple honeycomb holes, hemispherical grooves, and through holes. A fixing cylinder is disposed within each through hole. Two partitions are disposed within the fixing cylinder, dividing the fixing cylinder into three cavities. An inlet pipe and an outlet pipe are disposed on the fixing cylinder. Connecting pipes are disposed on the two partitions. The opposite ends of the inlet pipe and the outlet pipe pass through the two partitions sequentially and communicate with the left and right cavities respectively. The two ends of the connecting pipe communicate with the left and right cavities respectively. The inlet pipe has multiple perforations that communicate with the middle cavity. The opposite ends of the inlet pipe and the outlet pipe face the decorative layer and the substrate layer respectively.

[0006] Furthermore, the cavity is provided with multiple protrusions.

[0007] Furthermore, the axes of two adjacent honeycomb holes are asymmetrically staggered.

[0008] Furthermore, the opening edge of the hemispherical groove is constructed with an inwardly extending annular fold.

[0009] Furthermore, the honeycomb holes are provided with sequentially distributed ring plates, sound insulation cores, and sound insulation cotton. The opposite sides of the ring plates and sound insulation cotton face the decorative layer and the substrate layer, respectively. The sound insulation core is constructed with multiple through grooves, and the inner wall of the ring plates is provided with multiple protrusions.

[0010] Furthermore, the ring plate is constructed in a conical shape with its tip pointing towards the sound insulation core.

[0011] Furthermore, it also includes a frame, on which an installation cavity is constructed. The substrate layer, decorative layer, protective layer, and noise reduction layer are all movably embedded in the installation cavity. The substrate layer is constructed with an annular groove. An annular plate that is inserted and engaged with the annular groove is provided in the installation cavity. Limiting grooves are constructed at the four corners of the decorative layer. Limiting members that act on the limiting grooves and limit or release the limiting of the decorative layer are provided at the four corners of the frame.

[0012] Furthermore, the limiting component includes a limiting plate with a countersunk hole. The frame has a communicating positioning groove and a threaded hole. The positioning groove and the limiting groove are connected. The limiting plate is inserted into the positioning groove and the limiting groove. A limiting bolt that is threaded into the threaded hole is movably inserted into the countersunk hole.

[0013] The beneficial effects of this application are as follows: When in use, this application achieves first-level noise reduction through the noise reduction performance of the noise reduction layer itself, second-level noise reduction through multiple honeycomb holes, and third-level noise reduction through multiple hemispherical grooves. Through the combined action of through holes, fixed cylinder, two partitions, three cavities, inlet pipe, outlet pipe, connecting pipe and multiple perforations, a triple noise reduction is formed, thereby achieving multiple noise reductions. It does not require the stacking of multiple layers of sound-absorbing materials, which helps to reduce the overall thickness and is therefore more practical. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown in the figure, an embodiment of this application proposes a noise-reducing bamboo-wood fiber integrated wall panel, including a substrate layer 1, a decorative layer 2, and a protective layer. The protective layer is located on the side of the decorative layer 2 away from the substrate layer 1 and is not shown in the accompanying drawings. A noise-reducing layer 3 is disposed between the substrate layer 1 and the decorative layer 2. The noise-reducing layer 3 is made of sound-absorbing material. The substrate layer 1, the noise-reducing layer 3, and the decorative layer 2 are all vertically oriented and distributed sequentially. The side of the substrate layer 1 away from the noise-reducing layer 3 faces the wall. The noise-reducing layer 3 is constructed with a plurality of honeycomb holes 4, hemispherical grooves 5, and through holes 6. The plurality of honeycomb holes 4, hemispherical grooves 5, and through holes 6 are arranged in an array. The honeycomb holes 4 and through holes 6 are both horizontally oriented. A fixing cylinder 7 is disposed in the through hole 6. The fixing cylinder 7 is horizontally oriented and fixed in the through hole 6. Two partitions 8 are disposed in the fixing cylinder 7. The two partitions 8 are both horizontally oriented. The tubes are vertically and spaced within the fixed cylinder 7, which is divided into three cavities 9 by two partitions 8. The fixed cylinder 7 is provided with an inlet pipe 10 and an outlet pipe 11, both of which are horizontal and fixed to the fixed cylinder 7. The two partitions 8 are provided with connecting pipes 12, which are horizontal and fixed to the two partitions 8. The connecting pipes 12, inlet pipes 10, and outlet pipes 11 are distributed from top to bottom at intervals. The opposite ends of the inlet pipes 10 and outlet pipes 11 pass through the two partitions 8 and are respectively connected to the left and right cavities 9. The two ends of the connecting pipes 12 are respectively connected to the left and right cavities 9. The inlet pipes 10 are constructed with multiple perforations 13 that are all connected to the middle cavity 9. The perforations 13 are honeycomb shaped. The opposite ends of the inlet pipes 10 and outlet pipes 11 face the decorative layer 2 and the substrate layer 1, respectively.

[0025] During installation, the side of the substrate layer 1 away from the noise reduction layer 3 faces the wall. During use, the noise reduction layer 3 achieves first-level noise reduction through its own noise reduction performance. Some noise enters multiple honeycomb holes 4, and the friction and viscosity loss of sound waves in the micro-channels absorb the noise, achieving second-level noise reduction. Some noise enters the hemispherical groove 5, guiding the sound waves to reflect multiple times in the hemispherical groove 5, extending the sound energy attenuation path, achieving third-level noise reduction. Some noise enters the inlet pipe 10, right cavity 9, connecting pipe 12, left cavity 9 and outlet pipe 11 in sequence. During this process, when the noise in the inlet pipe 10 passes through the middle cavity 9, some noise will pass through multiple perforations 13 and be reflected multiple times in the middle cavity 9. When the noise enters the right cavity 9 from the inlet pipe 10, some noise will be reflected multiple times in the right cavity 9. When the noise enters the left cavity 9 from the connecting pipe 12, some noise will be reflected multiple times in the left cavity 9, achieving fourth-level noise reduction.

[0026] In summary, when this application is used, it achieves first-level noise reduction through the noise reduction performance of the noise reduction layer 3 itself, second-level noise reduction through multiple honeycomb holes 4, and third-level noise reduction through multiple hemispherical grooves 5. The triple noise reduction is achieved through the combined action of through holes 6, fixing cylinders 7, two partitions 8, three cavities 9, inlet pipe 10, outlet pipe 11, connecting pipe 12, and multiple perforations 13. Thus, multiple noise reductions are achieved without the need for multiple layers of sound-absorbing materials, which helps to reduce the overall thickness and is therefore more practical.

[0027] like Figure 3 As shown, in some embodiments, a plurality of protrusions 14 are provided in the cavity 9, and the plurality of protrusions 14 are fixed in the cavity 9 and evenly distributed.

[0028] Referring to the above, when noise is reflected multiple times within cavity 9, the number of noise reflections can be increased by setting multiple bumps 14, which is more conducive to noise reduction.

[0029] like Figure 5 As shown, in some embodiments, the axes of two adjacent honeycomb holes 4 are asymmetrically staggered.

[0030] Referring to the above, when in use, the asymmetrical staggered distribution can break the straight propagation path of sound waves, forcing sound waves to reflect multiple times within the honeycomb holes 4, increasing sound energy loss, and at the same time reducing the sound wave superposition resonance phenomenon caused by periodic arrangement, which is more conducive to noise reduction.

[0031] like Figure 5 As shown, in some embodiments, the opening edge of the hemispherical groove 5 is constructed with an inwardly extending annular fold 15.

[0032] Referring to the above, during use, the annular fold 15 can guide the sound waves to converge towards the center of the hemispherical groove 5, reducing the direct reflection and dissipation of sound waves at the edge of the opening, which is more conducive to noise reduction.

[0033] like Figure 4 As shown, in some embodiments, a ring plate 16, a sound insulation core 17, and a sound insulation cotton 18 are arranged sequentially inside the honeycomb holes 4. The ring plate 16, the sound insulation core 17, and the sound insulation cotton 18 are all fixed inside the honeycomb holes 4. The opposite sides of the ring plate 16 and the sound insulation cotton 18 face the decorative layer 2 and the substrate layer 1, respectively. The sound insulation core 17 is constructed with a plurality of through grooves 19. The through grooves 19 are constructed in a honeycomb shape. The plurality of through grooves 19 are horizontal and arranged in a ring array. The inner wall of the ring plate 16 is provided with a plurality of protrusions 20. The plurality of protrusions 20 are fixed on the inner wall of the ring plate 16 and are evenly distributed.

[0034] Referring to the above, when noise enters the honeycomb hole 4 during use, it will first pass through the ring plate 16, and the sound waves will collide and be transmitted between multiple protrusions 20 to disperse the sound waves. Then the sound waves will be transmitted to multiple through slots 19 on the sound insulation core 17 and reflected multiple times to further disperse the sound waves. Finally, the sound insulation cotton 18 will be used to insulate the sound waves, which is more conducive to noise reduction.

[0035] like Figure 4 As shown, in some embodiments, the ring plate 16 is constructed in a conical shape with the tip pointing towards the sound insulation core 17;

[0036] Referring to the above, the conical structure of the ring plate 16, which is larger at one end and smaller at the other, can concentrate sound waves to a certain extent, which is more conducive to noise reduction.

[0037] like Figures 1-8 As shown, in some embodiments, a frame 21 is also included. The frame 21 has an installation cavity 22. The substrate layer 1, decorative layer 2, protective layer and noise reduction layer 3 are all movably embedded in the installation cavity 22. The substrate layer 1 has an annular groove 23. An annular plate 24 that is inserted into the annular groove 23 is provided in the installation cavity 22. The annular plate 24 is vertical and fixed in the installation cavity 22. Limiting grooves 25 are provided at the four corners of the decorative layer 2. Limiting members that act on the limiting grooves 25 and limit or release the limiting of the decorative layer 2 are provided at the four corners of the frame 21.

[0038] Referring to the above, during installation, the substrate layer 1, decorative layer 2, protective layer, and noise reduction layer 3 are all movably embedded in the mounting cavity 22. The annular plate 24 is correspondingly and completely inserted into the annular groove 23 for positioning. Then, four limiting members act on the four limiting grooves 25 to limit the decorative layer 2 together. After that, the side of the substrate layer 1 away from the noise reduction layer 3 faces the wall. The frame 21 can be fixed to the wall by driving mounting nails into it to achieve the installation of the integrated wall panel. Compared with the existing technology of directly driving mounting nails into the integrated wall panel, this method will not damage the structure of the integrated wall panel. Conversely, the decorative layer 2 can be released by the four limiting members together, so that the substrate layer 1, decorative layer 2, protective layer, and noise reduction layer 3 can all be removed from the mounting cavity 22 to facilitate the disassembly and replacement of the integrated wall panel.

[0039] like Figures 1-8 As shown, in some embodiments, the limiting member includes a limiting plate 26, which is vertical and has a countersunk hole 27 in a horizontal direction. The frame 21 has a communicating positioning groove 28 and a threaded hole 29. The positioning groove 28 is communicating with the limiting groove 25. The limiting plate 26 is inserted into the positioning groove 28 and the limiting groove 25. A limiting bolt 30 that is threaded into the threaded hole 29 is movably inserted into the countersunk hole 27.

[0040] Referring to the above, during installation, the limiting plate 26 is inserted into the positioning groove 28 and the limiting groove 25, and the countersunk hole 27 is connected to the threaded hole 29. Then, the limiting bolt 30 is tightened. The limiting bolt 30 is threadedly engaged with the threaded hole 29, and the limiting plate 26 cannot move, thus limiting the decorative layer 2. Conversely, the limiting bolt 30 is loosened, and the threaded engagement between the limiting bolt 30 and the threaded hole 29 is released, so that the limiting plate 26 is moved away from the positioning groove 28 and the limiting groove 25, and the decorative layer 2 is released from limitation.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
