Description

Technical Field

[0001] This utility model belongs to the field of glass technology, specifically relating to louvered glass, and more particularly to a multi-layer composite sound-insulating built-in louvered glass assembly. Background Technology

[0002] Built-in venetian blinds are functional building components that integrate venetian blind structures into glass interlayers. They offer advantages such as light regulation, privacy protection, and architectural aesthetics, and have been widely used in various types of buildings in recent years. Their core typically uses a double or triple glazing structure with adjustable venetian blinds installed in the middle cavity (hollow layer). This structure itself utilizes the physical properties of the air layer and glass to a certain extent, providing better sound insulation (especially in the mid-to-high frequency range) and thermal insulation performance than ordinary single-pane glass.

[0003] However, the current mainstream frame-type built-in louver glass components often focus on the glass panel itself and the operation function of the louvers in their design. As for the internal frame structure that supports, separates and carries the entire louver system, the overall frame is mostly made of thin-walled metal profiles (such as aluminum alloy, stainless steel sheet, etc.).

[0004] However, from the perspective of architectural acoustics, this frame structure becomes the weakest link in the entire component's sound insulation chain, the so-called "sound bridge" or "sound insulation bottleneck." Metal materials themselves have high density and rigidity, and their thin-walled structure is prone to resonance and efficient sound wave transmission under the action of sound waves. Specifically, when sound waves act on the glass component, part of the sound energy is transmitted through the glass panel, and the other part is transmitted through the solid structure of the frame. The damping performance of the thin-walled metal frame is usually poor, and its attenuation effect on sound vibration is limited, which makes it relatively easy for sound to pass through the component along the frame path, thereby weakening the sound insulation effect that the insulated glass layer itself can provide. This solid-borne sound transmission effect is particularly prominent for low-frequency noise.

[0005] Therefore, how to solve the problem of the glass frame weakening the sound insulation effect of the glass component due to solid sound transmission is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0029] Research has revealed the shortcomings of existing technologies: the design focus of the mainstream frame-type built-in louver glass components on the market is often on the glass panel itself and the operation function of the louvers, while the internal frame structure that supports, separates and carries the entire louver system is mostly made of thin-walled metal profiles (such as aluminum alloy, stainless steel sheet, etc.).

[0030] However, from the perspective of architectural acoustics, this frame structure becomes the weakest link in the entire component's sound insulation chain, the so-called "sound bridge" or "sound insulation bottleneck." Metal materials themselves have high density and rigidity, and their thin-walled structure is prone to resonance and efficient sound wave transmission under the action of sound waves. Specifically, when sound waves act on the glass component, part of the sound energy is transmitted through the glass panel, and the other part is transmitted through the solid structure of the frame. The damping performance of the thin-walled metal frame is usually poor, and its attenuation effect on sound vibration is limited, which makes it relatively easy for sound to pass through the component along the frame path, thereby weakening the sound insulation effect that the insulated glass layer itself can provide. This solid-borne sound transmission effect is particularly prominent for low-frequency noise.

[0031] Therefore, how to solve the problem of the glass frame weakening the sound insulation effect of the glass component due to solid sound transmission is a technical problem that urgently needs to be solved in this field.

[0032] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] like Figures 1 to 3As shown, some embodiments provide a multi-layer composite sound-insulating built-in louvered glass assembly, including: a frame 1, with inlay grooves 11 on the inner edges of both sides; the frame 1 is a multi-layer composite structure, including at least one damping constraint layer; the frame 1 is the supporting skeleton of this assembly and is also the key innovation of this embodiment in solving the sound insulation shortcomings. Unlike traditional single-material metal profiles, the frame 1 in this embodiment is a multi-layer composite structure, which includes at least one damping constraint layer. The principle is that when sound wave vibration is transmitted to the frame 1, the structure composed of materials with different densities and elastic moduli (such as metal layers and polymer damping material layers) will produce shear deformation at the interface of each layer. As a viscoelastic material, the damping constraint layer can efficiently convert the energy of this mechanical vibration (sound wave) into heat energy and dissipate it, thereby significantly suppressing the structural vibration of the frame 1 itself and fundamentally weakening the "sound bridge effect".

[0036] The composite frame 1 provides a stable mounting base for the internal sound-absorbing structure 13, and the vibration of the structure itself is suppressed. The two work together to achieve dual control of sound transmission from the source and path of the structure. Furthermore, by adopting a multi-layer composite structure, the solid-borne sound transmission of the frame 1 itself is effectively suppressed, vibration radiation noise is reduced, and the basic sound insulation of the component is improved.

[0037] Precision grooves 11 are provided on the inner edges of both sides of the frame 1. The principle is not only to provide precise mechanical positioning for the glass 2 and ensure structural stability, but more importantly, to provide a standardized filling and bonding space for high airtightness and high watertightness sealing materials (such as silicone structural adhesive, butyl adhesive, etc.). A continuous and full sealant line can effectively block the leakage path of air noise through the gap between the glass 2 and the frame 1.

[0038] The recessed groove 11 on the frame 1 ensures the accuracy of glass 2 installation and the reliability of sealing; good sealing is a prerequisite for maintaining the performance of the vacuum chamber; by setting the recessed groove 11, the precise assembly and reliable sealing between glass 2 and frame 1 are achieved, effectively eliminating potential air sound leakage gaps and laying a structural foundation for the overall sound insulation performance.

[0039] Glass 2 is set in the mounting groove 11, and a vacuum cavity is formed between the two glass 2 and the frame 1. The glass 2 is fixed in the mounting groove 11 by sealing material, usually tempered glass, laminated glass or Low-E glass. The two glass 2 and the frame 1 together form a vacuum cavity. The principle is based on the mass law of glass itself, that is, the higher the surface density, the stronger the ability to isolate airborne sound. Secondly, the two layers of glass 2 constitute a "mass-air-mass" resonance system, which can effectively attenuate sound in a specific frequency band. More importantly, combined with feature 12, the vacuum or inert gas layer formed greatly improves the heat insulation and sound insulation performance.

[0040] Glass 2 provides a protected and stable internal environment for louver structure 3. The beneficial effect is that by setting glass 2, effective sound transmission through the air is blocked, and as a basic component for forming a high-performance hollow / vacuum cavity, it constitutes the first major sound barrier of the entire assembly.

[0041] Vacuum cavity: A vacuum cavity (or a hollow cavity filled with inert gas) formed by sealing two glass panes 2 with the frame 1. Its core principle is to eliminate or significantly reduce the air medium. In a vacuum or low-pressure state, air molecules are extremely rarefied and cannot effectively transmit sound wave vibrations, thus almost completely blocking the sound energy transmitted through the air. At the same time, it also greatly reduces the heat transfer through convection and conduction. Its relationship with feature 2 is a structural relationship. Its relationship with features 1 and 11 is that the stability of the frame 1 and the sealing of the embedded groove 11 are the guarantee for maintaining the long-term performance of the vacuum cavity. By forming a vacuum cavity, almost complete isolation of sound transmission through the air and excellent thermal insulation performance are achieved. This is a key technical means to improve the overall performance of the component.

[0042] And a louver structure 3 set inside the vacuum cavity; the louver structure 3 is set inside the vacuum cavity and consists of adjustable blades and its control system. In terms of acoustics, its blade array forms a complex acoustic interface. When sound waves are introduced, they will be reflected, scattered and diffracted multiple times on the surface of the blades. This process can disrupt the direction of the sound waves and consume some sound energy. In particular, it has a certain diffusion and weakening effect on mid-to-high frequency sounds.

[0043] The louver structure 3 is located within the sealed protective space formed by the glass 2 and the vacuum cavity. Its function does not depend on external cleaning, and its acoustic effect is a secondary treatment that occurs after the airborne sound has been significantly attenuated by the glass 2 and the vacuum cavity. By setting the louver structure 3, the functionality of the component in terms of light adjustment and privacy control is improved. At the same time, its structural characteristics can also scatter and weaken the residual sound waves entering the cavity, providing an auxiliary acoustic improvement effect.

[0044] The frame 1 has a cavity 12, which is a cavity formed inside the frame 1 itself. The principle is that it provides an extended and buffered space for the propagation of sound waves in the internal structure of the frame 1. When the vibration (sound) propagates along the wall of the frame 1 to this point, the cavity 12 changes the boundary conditions of the sound wave, which may cause a sudden change in acoustic impedance, resulting in some sound energy being reflected. At the same time, it provides physical space for installing a more complex sound-blocking structure 13. By setting the cavity 12 in the frame 1, an installation position is provided for the subsequent sound-blocking structure 13, and by changing the boundary conditions of sound wave propagation, some of the structural sound propagating along the frame is initially consumed and reflected.

[0045] A sound-absorbing structure 13 is provided inside the cavity 12. The sound-absorbing structure 13 is constructed to attenuate the sound waves propagating through the frame 1. The sound-absorbing structure 13 is a device specifically designed to attenuate the structural sound propagating through the frame 1, which is located inside the cavity 12 of the frame 1. It is an integrated acoustic processing module. Its principle is to comprehensively utilize multiple acoustic mechanisms such as Helmholtz resonance, porous sound absorption and microstructure diffusion. When vibration (sound wave) is transmitted to the frame 1 and excites the air movement inside the cavity 12, the sound-absorbing structure 13 will capture, guide and convert this sound energy as a whole.

[0046] The sound-damping structure 13 is installed inside the damped frame 1 to deal with the remaining structural vibration energy that has been initially attenuated. Specifically, by integrating the sound-damping structure 13, an "acoustic trap" is constructed for the sound of the frame structure, which can actively and efficiently absorb and dissipate the vibration energy propagating along the metal frame, thus completely making up for the sound insulation shortcomings of traditional components.

[0047] The sound-absorbing structure 13 includes several equally spaced sound-collecting tubes 131 arranged in the cavity 12; the inner contour of the sound-collecting tube 131 is rectangular or horn-shaped with open ends; the sound-collecting tube 131 is one of the core components of the sound-absorbing structure 13, and several are equally spaced in the cavity 12 of the frame 1. Its inner contour is designed to be rectangular or horn-shaped with open ends. The principle is that the horn-shaped or specifically shaped cavity first acts as a "sound funnel", which can more effectively collect and guide the sound waves radiated from the frame wall into the cavity 12 into the processing area.

[0048] Each microphone 131 can be considered a variant of a Helmholtz resonator or a quarter-wave tube. Its specific geometry (such as neck size and cavity depth) enables it to strongly resonate and absorb sound waves at specific frequencies (especially low frequencies that are difficult to handle), concentrating and dissipating sound energy within the cavity. By setting a specific inner contour for the microphone 131, directional collection of structural sound and resonant absorption of specific low-frequency noise are achieved, significantly improving the ability of the sound-absorbing structure 13 to handle broadband noise, especially low-frequency noise.

[0049] The microphone 131 is provided with at least one sound-absorbing ring 132; the sound-absorbing ring 132 is made of open-cell foam, glass wool, rock wool or polyester fiber; the surface of the sound-absorbing ring 132 is evenly distributed with pits 133.

[0050] The sound-absorbing ring 132 is located inside the receiver tube 131 and is made of porous sound-absorbing materials such as open-cell foam, glass wool, rock wool or polyester fiber. Its principle is based on the viscosity and thermal effect of porous materials. When the sound waves collected and guided by the receiver tube 131 enter the ventilation channel of the sound-absorbing ring 132, they will cause the air molecules in the pores to vibrate. The air molecules will rub against the complex and tortuous pore walls, thereby irreversibly converting the mechanical energy of the sound wave vibration into heat energy. This sound absorption mechanism is particularly effective for mid-to-high frequency sounds.

[0051] The sound-absorbing ring 132 is placed inside the receiver tube 131. Benefiting from the sound wave collection and pre-processing (such as resonance) of the receiver tube 131, more sound energy, especially the concentrated sound energy, can be efficiently converted. It should be further noted that the pit 133 further increases its effective working surface area. By setting the porous material sound-absorbing ring 132 inside the receiver tube 131, the ability to efficiently convert mid-to-high frequency sound energy into heat energy is obtained, which complements the low-frequency resonance absorption of the receiver tube 131, and achieves effective sound absorption over a wide frequency range.

[0052] The surface of the sound-absorbing ring 132 is evenly distributed with pits 133. The principle behind this is multifaceted: First, it greatly increases the effective surface area of ​​the sound-absorbing ring 132 in contact with the air, allowing more sound waves to interact with the material. Second, these regular or irregular pits form a microscopic acoustic impedance gradient layer. Before entering the main body of the sound-absorbing ring 132, the sound waves pass through this gradient layer, which can reduce the direct reflection of the sound waves on the material surface and improve the efficiency of the sound waves entering the interior of the material (i.e., reduce the surface acoustic impedance and improve impedance matching). Third, the pits 133 can effectively scatter and diffuse the incident sound waves, disrupt the direction of the sound waves, and prolong the propagation path of the sound waves near the material surface, thereby increasing the chance of them being absorbed.

[0053] Specifically, by setting pits 133 on the surface of the sound-absorbing ring 132, the surface sound energy capture efficiency and overall sound absorption coefficient of the sound-absorbing ring 132 are improved, especially its absorption stability for sound waves at different incident angles is enhanced, resulting in better sound absorption performance and a wider frequency band.

[0054] Some embodiments provide a multi-layer composite sound-insulating built-in louvered glass assembly, including: a frame 1, on which inlay grooves 11 are provided on the inner edges of both sides; glass 2, which is disposed on the inlay grooves 11, and a vacuum cavity is formed between the two glass 2 and the frame 1; and a louvered structure 3 disposed in the vacuum cavity; the frame 1 has a cavity 12, and the frame 1 is a multi-layer composite structure, including at least one damping constraint layer.

[0055] A sound-blocking structure 13 is provided inside the cavity 12. The sound-blocking structure 13 is configured to attenuate the sound waves propagating through the frame 1.

[0056] The sound-absorbing structure 13 includes several equally spaced sound tubes 131 arranged in the cavity 12; the inner contour of the sound tube 131 is rectangular or horn-shaped with open ends; at least one sound-absorbing ring 132 is provided inside the sound tube 131; the sound-absorbing ring 132 is made of open foam, glass wool, rock wool or polyester fiber; the surface of the sound-absorbing ring 132 is evenly distributed with pits 133.

[0057] When external noise (airborne noise and structural impact noise) acts on this multi-layered composite soundproof glass module with built-in louvers, its sound insulation process works synergistically as follows: First line of defense: Airborne sound isolation and initial structural sound suppression: Process: The sound waves propagating through the air first impact the outer glass 2. The glass 2 resists the vibration due to its mass inertia, reflects and loses some of the sound energy. After the sound waves excite the glass to vibrate, they attempt to propagate through the vacuum cavity between the two glass layers 2. However, the vacuum environment almost completely blocks the air transmission path. At the same time, the vibration generated by the impact is transmitted to the frame 1 through the glass 2.

[0058] The vacuum cavity achieves ultimate isolation of airborne sound. At the same time, the multi-layer composite structure (damping constraint layer) of the frame 1 itself begins to work, converting some of the vibration energy transmitted into the frame into heat energy dissipation, which significantly suppresses the primary vibration of the "sound bridge".

[0059] Second line of defense: Internal sound field disruption and residual structural sound collection: Process: A very small amount of sound waves (or sound waves that mainly enter through other paths) enter the internal space through the vacuum cavity and encounter the louver structure 3. The louver blades scatter and reflect the sound waves, disrupting their propagation direction and consuming some energy. The structural sound propagating through the frame 1 vibrates and excites the air movement in the frame cavity 12.

[0060] The louvered structure 3 provides auxiliary sound diffusion, and the frame cavity 12 provides space for the conversion of structural sound (from solid vibration to air vibration) and subsequent processing.

[0061] The third line of defense: targeted absorption and dissipation of structural sound. Process: The sound waves (which have been converted into airborne sound) entering the cavity 12 of the frame are captured by the equally spaced microphones 131. The horn-shaped inlet of the microphones 131 efficiently collects the sound waves. The geometry of the cavity resonates with specific low frequencies, concentrating the low-frequency sound energy. After the sound waves enter the microphones 131, they first act on the sound-absorbing rings 132 with pits 133 on the surface. The pits 133 enhance the capture of the sound waves and promote their entry into the porous material of the sound-absorbing rings 132.

[0062] The microphone 131 achieves targeted collection and resonant absorption of structural sound, especially low-frequency components, while the recess 133 optimizes the impedance matching process of sound waves entering the sound-absorbing material.

[0063] Ultimate dissipation: The ultimate conversion of sound energy into heat energy: Process: Sound waves entering the porous material of the sound-absorbing ring 132 cause intense friction and viscous movement between air molecules and the fiber pore walls in the intricate microchannels.

[0064] The mechanical energy of sound waves is efficiently and irreversibly converted into a small amount of heat energy, thereby achieving the final and complete dissipation of sound energy. The sound-absorbing ring 132 completes the final elimination of broadband sound energy, especially mid-to-high frequency sound energy.

[0065] In summary, this embodiment: By setting up a multi-layered composite frame 1, structural vibration was suppressed at the source, effectively reducing the "sound bridge" effect; By setting a precise embedding groove 11, a high airtight seal between the glass 2 and the frame 1 is achieved, eliminating sound leakage gaps. By setting up a vacuum chamber, near-perfect sound blocking capability and excellent thermal insulation performance were achieved. By setting the louver structure 3, the light adjustment function of the component and the diffusion ability of the internal sound field are improved. By setting the frame cavity 12, an installation space is provided for the sound-absorbing structure 13 and a preliminary sound attenuation zone is formed; By integrating the sound-absorbing structure 13, a dedicated high-efficiency processing unit for structural sound was constructed. By setting the receiver 131 with a horn-shaped inner contour, efficient collection of sound waves and low-frequency resonance absorption are achieved. By setting a porous material sound-absorbing ring 132, a highly efficient broadband sound absorption capability that converts mid-to-high frequency sound energy into heat energy is achieved. By setting surface pits 133, the sound wave capture efficiency and sound absorption performance of the sound-absorbing ring 132 are improved.
