Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing decorative materials, and more specifically to a sound absorber. Background Technology

[0002] Polyester fiber sound absorbers are widely used in the field of building decoration because they combine sound absorption performance and decorative effect. With the increasing demand for environmental protection, products that integrate the function of adsorbing harmful substances have emerged, such as the invention patent with publication number CN111648036A. It achieves glue-free environmental protection, sound absorption and adsorption integration by adding adsorption components such as carbon particles and diatomaceous earth. However, existing technologies still have key pain points.

[0003] 1. Inconvenient installation and replacement: Traditional products are mostly fixed with glue or special hardware. After installation, the surface cannot be flexibly changed. Later modifications require disassembling the hardware or cleaning the glue, which is cumbersome. Some detachable products use magnetic structure, which can achieve quick replacement, but increases the purchase cost of magnets and assembly process. Moreover, strong magnets can cause electromagnetic interference to electronic equipment in special environments such as computer rooms and audio-visual rooms, which poses a safety hazard.

[0004] 2. Unreasonable structural design: Existing brackets are either too heavy or lack a convenient disassembly structure, making it difficult to balance installation strength, lightweight and ease of operation; magnetic structures also have problems such as adsorption displacement and magnetic force attenuation over long-term use.

[0005] Therefore, there is an urgent need to develop a quick-install sound absorber that is flexible in installation, easy to disassemble, cost-controllable, and free from electromagnetic interference, in order to solve the pain points of existing technologies. Summary of the Invention

[0006] The purpose of this utility model is to provide a tool-free, quick-installation 3D-shaped sound absorber that can be easily replaced by hand, shortens the time for styling and modification, is convenient and efficient to operate, reduces product costs, avoids electromagnetic interference hazards, and is suitable for special scenarios such as computer rooms and audio-visual rooms.

[0007] The present invention achieves the above objectives by adopting the following technical solution: a snap-on quick-installation 3D shaped sound absorber, characterized in that it includes a 3D shaped polyester fiber component for realizing sound absorption, decoration and adsorption of harmful substances, wherein the 3D shaped polyester fiber component is formed by hot pressing polyester fiber board.

[0008] The bracket is detachably fastened to the 3D shaped polyester fiber part. The bracket has a slot that runs through both sides. A through groove is opened at the bottom of the slot. The width and depth of the through groove are adapted to the slot to facilitate the molding and demolding of the slot.

[0009] The fastening components, including self-tapping screws and expansion plugs, are used to secure the bracket to the wall substrate.

[0010] As a further explanation of the above solution, the bracket is an integral injection-molded structure made of engineering plastics.

[0011] Furthermore, the corners of the bracket are provided with spherical grooves, and there is no rounded transition between the spherical grooves and the slots.

[0012] Furthermore, the spherical groove has an inwardly concave arc-shaped structure, which is used to pry up the 3D shaped polyester fiber part by hand to achieve quick replacement.

[0013] Furthermore, the 3D shaped polyester fiber parts are provided with multiple sound-absorbing surfaces.

[0014] Furthermore, the bracket is plate-shaped, with its outer edge bent inward to form a side, and the edge of the 3D shaped polyester fiber part is tightly attached to the side; the bracket is provided with multiple stamping grooves and / or hollow holes.

[0015] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0016] 1. This utility model adopts a quick-installation sound-absorbing body structure mainly composed of 3D-shaped polyester fiber parts, brackets, and fixing components. The snap-on structure combined with the concave spherical force application design enables quick manual assembly and disassembly, improving replacement efficiency by more than 90% compared to traditional glue installation. Compared to magnetic products, it reduces the tedious steps of magnetic alignment and eliminates the risk of magnetic attenuation. It excels in cost and safety, eliminating magnetic components, saving on magnet procurement costs and assembly processes. The one-piece injection-molded bracket simplifies the production process, reducing the overall product cost by 20%-30%. At the same time, it completely avoids electromagnetic interference from strong magnets to electronic equipment, making it safe for use in special scenarios such as computer rooms, audio-visual rooms, and precision instrument rooms, thus broadening its applicability.

[0017] 2. Enhanced structural stability: The through-hole design of the card slot, combined with precise size adaptation, ensures a firm and secure fit after fastening, eliminating the offset issues of magnetic products; the bracket has been optimized through stress analysis, and the one-piece injection molding ensures structural strength; the through groove at the bottom of the card slot facilitates molding and demolding while reducing weight, balancing the requirements of strength and lightweight design.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1-4 As shown, this utility model is a snap-on quick-installation 3D shaped sound absorber, which consists of three parts: a 3D shaped polyester fiber component 1, a bracket 2, and a fixing component 3. The bracket 2 is detachably snapped onto the 3D shaped polyester fiber component 1, and the fixing component 3 is used to fix the bracket to the wall base.

[0029] The 3D shaped polyester fiber component 1 serves as the core functional part, combining sound absorption, decoration, and harmful substance adsorption functions. It is formed by hot pressing polyester fiberboard, and the 3D three-dimensional shape can be customized (such as honeycomb, wave, geometric protrusion). In this embodiment, the 3D shaped polyester fiber component 1 is provided with multiple sound-absorbing planes 1-1, and the surface color supports a variety of choices and color matching. After being attached to the wall, it forms a natural cavity with a thickness of 5-80mm, eliminating the need for additional framing, reducing sound vibration transmission, enhancing the sound absorption and noise reduction effect, and especially improving the low-frequency sound absorption performance. The adsorbed components fully contact the air through the pores between the fibers, and the formaldehyde adsorption efficiency reaches more than 85%. Raw material composition (by weight): 10-20 parts low-melting-point polyester staple fiber (melting point 160℃-200℃), 10-60 parts conventional polyester staple fiber (melting point 250℃-270℃), 1-3 parts carbon particles (bamboo charcoal or activated carbon, particle size 150-190 mesh), 0.5-2.5 parts diatomaceous earth, 0.2-2 parts graphene, 0.8-3.5 parts biochar, and 5-10 parts enhanced adsorption components (equal parts of slag wool, sponge, rock wool, maifanite, bentonite, zeolite, kaolin, and chitosan).

[0030] The bracket 2 serves as a load-bearing and snap-fit ​​positioning component, precisely fitting the absorbent 3D-shaped polyester fiber part. Overall structure: The bracket is plate-shaped with a hexagonal structure. The outer edge of the bracket bends inward to form side 2-1, and the edge of the 3D-shaped polyester fiber part fits tightly against side 2-1. The bracket has multiple perforated holes 2-2. Alternatively, it can be designed as a stamped groove to enhance mechanical properties. The bracket 2 and the 3D-shaped polyester fiber part 1 are dimensionally matched and integrally injection molded using engineering plastics such as ABS, PP, or PE, resulting in efficient production and strong structural stability. The bracket 2 has through-slots 2-3 on both sides. The width of the slots precisely matches the snap-fit ​​end dimensions (14~16mm) of the 3D-shaped polyester fiber part, ensuring a tight and secure fit. A through-slot 2-4 is opened at the bottom of the slot 2-3, with its width and depth corresponding to the slot, facilitating the molding and demolding of the slots during injection molding and effectively reducing the overall weight of the bracket. The bracket 2 has concave arc-shaped spherical grooves 2-4 at each of its six corners. There is no rounded transition between the spherical grooves 2-4 and the slots 2-3, forming a clear force application groove that fits the finger's force application habits and makes it easy to quickly separate the polyester fiber part from the bracket by hand.

[0031] The fixing component 3 includes self-tapping screws 3-1 and expansion granules 3-2. Each bracket is equipped with 6 self-tapping screws and 6 expansion granules, which are suitable for different types of wall bases such as concrete and gypsum board, ensuring that the bracket fits flat against the wall without loosening after installation.

[0032] Installation steps:

[0033] (1) Mark 6 evenly distributed mounting holes (corresponding to screw holes on the bracket) at the predetermined position on the wall base.

[0034] (2) Use an impact drill to drill an installation hole at the marked hole position that is compatible with the expansion granules, and embed the expansion granules into the hole and fit them tightly against the hole wall.

[0035] (3) Align the plastic fixing bracket with the hole and tighten it with the self-tapping screws in sequence to make the bracket firmly fixed to the wall base without shaking;

[0036] (4) Align the snap-fit ​​end of the 3D shaped polyester fiber part with the through slot of the bracket, and push it in parallel along the direction of the slot until it is snapped in place to complete the installation; at this time, the polyester fiber part and the wall form a natural cavity, and no additional keel is required.

[0037] Replacement steps:

[0038] The user inserts their finger into the spherical groove at any corner of the plastic mounting bracket and applies a pulling force away from the wall. The force fulcrum of the spherical groove is used to disengage the polyester fiber part from the slot. After removing the old part, the new 3D shaped polyester fiber part is aligned with the slot and pushed in to fasten. The entire process requires no tools and takes no more than 30 seconds.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
