Description

Technical Field

[0001] The present invention relates to the field of soundproof window structures, and in particular to a soundproof window with optimized low-frequency noise processing and an installation method thereof. Background Art

[0002] With the improvement of living and working environment requirements, the requirements for heat insulation and sound insulation of windows are also increasing. The structural design of soundproof windows is to effectively isolate external noise and improve the quality of indoor sound environment.

[0003] The structure of a soundproof window generally includes a window frame, glass, sealing strips and soundproof strips. The window frame is the skeleton of the soundproof window, and is usually made of materials with good sealing performance, such as aluminum alloy or plastic. It not only supports the other parts of the window, but also blocks the sound propagation. In order to optimize the sound insulation and heat insulation effects, the current window frames are all set as broken bridges (sound bridges and cold bridges). For example, the aluminum alloy materials on both sides are connected by a polymer structure in the thickness direction of the window frame. While the polymer structure achieves structural strength, it weakens the heat conduction and sound conduction between the aluminum alloys on both sides. Glass is the main part of the soundproof window, and double or triple insulating glass is usually used. There is an air layer in the middle of this glass, which can reduce the propagation of sound waves. Some glass will also be coated with special sound insulation materials on the surface to further improve the sound insulation effect. The sealing strip is a material installed between the window frame and the glass to ensure the sealing performance of the window. It can effectively prevent the sound from propagating through the gap. The soundproof strip is a material installed between the window frame and the wall to block the sound from propagating through the gap between the window frame and the wall.

[0004] The frequency range of low-frequency noise usually refers to between 20 Hz and 200 Hz. Sound within this range can penetrate objects and propagate farther due to its longer wavelength, and is often difficult to be completely absorbed by conventional sound insulation materials, so it is challenging to prevent and control. Conventional window frames, glass, sealing strips and sound insulation strips are not designed to be adaptive to low-frequency noise, and the threat of low-frequency noise to human health is currently gaining more and more attention. Low-frequency noise has the characteristics of strong penetration and easy transmission through resonance effect, which makes windows have poor blocking effect on low-frequency noise. Summary of the invention

[0005] The main purpose of the present invention is to provide a soundproof window with optimized low-frequency noise processing and an installation method thereof, aiming to solve the problem that the settings of conventional window frames, glass, sealing strips and soundproof strips are not adaptively designed for low-frequency noise, and low-frequency noise has the characteristics of strong penetration and easy transmission through resonance effect, which makes the windows have poor blocking effect on low-frequency noise.

[0052] Reference Figures 1 to 7 In one embodiment of the present invention, a soundproof window with optimized low-frequency noise processing includes:

[0053] The profile frame 100 includes a first profile tube frame 110 located on a first side and a second profile tube frame 120 located on a second side in the thickness direction of the soundproof window, wherein the profile frame 100 is divided into an inner ring portion 030 and an outer ring portion 040 sleeved on the outer circumference thereof on the plane of the soundproof window;

[0054] The polymer connector 200 is in a ring shape on the plane of the soundproof window, and connects the first profile tube frame 110 and the second profile tube frame 120 in the thickness direction;

[0055] The glass panel portion 300 is disposed in the space enclosed by the inner ring portion 030 and is clamped by the first profile tube frame 110 and the second profile tube frame 120;

[0056] At least one tubular cavity is respectively provided in the thickness direction of the outer ring portion 040 corresponding to the first profile tube frame 110 and the second profile tube frame 120, and the tubular cavity has two outer ring wall structures in the thickness direction;

[0057] The profile frame 100 includes a plurality of inner ring wall structures 131 in the inner ring part 030, which are layered in the thickness direction of the soundproof window and have a total thickness greater than 6 mm. The profile frame 100 includes n outer ring wall structures 141 in the outer ring part 040, which are layered in the thickness direction of the soundproof window. The total thickness of the n outer ring wall structures 141 is greater than 10 mm. The n outer ring wall structures have i thickness sizes, n≥4, i≥2; the i thickness sizes are arranged from thin to thick as a1, a2...a i , then i / n≥50% and (a i -a i-1 ) / a i-1 ≥5%.

[0058] In the prior art, conventional window frames, glass, sealing strips and sound insulation strips are not adaptively designed for low-frequency noise, and the threat of low-frequency noise to human health is currently gaining more and more attention; low-frequency noise in noise has the characteristics of strong penetration and easy transmission through resonance effect, which makes windows have poor blocking effect on low-frequency noise.

[0059] In the present invention, the soundproof window may refer to a window sash or a window that can be directly installed on a wall, including a profile frame 100, a polymer connector 200, a glass panel portion 300 and a sound-absorbing filler. It should be noted that since the profile frame 100 needs to form a connection structure at the corner position, the polymer connector 200, the first sound-absorbing filler 510 and the second sound-absorbing filler 520 are not limited to forming a complete frame structure, and can be partially disconnected. The overall thickness of the soundproof window is 60 to 100 mm, preferably 75 to 90 mm. The greater the overall thickness, the greater the sound insulation and heat insulation effect.

[0060] The profile frame 100 includes a first profile tube frame 110 located at a first side in the thickness direction and a second profile tube frame 120 located at a second side in the thickness direction. The first side and the second side refer to two side surfaces (e.g., indoor side and outdoor side) in the thickness direction of the profile frame 100, respectively. The first profile tube frame 110 may include a plurality of first side profile tubes 111 and a first angle code piece connecting the plurality of first side profile tubes 111 end to end, and the second profile tube frame 120 may include a plurality of second side profile tubes 121 and a second angle code piece connecting the plurality of second side profile tubes 121 end to end. The profile frame 100 includes an inner ring portion 030 and an outer ring portion 040 connected to each other. The inner ring portion 030 and the outer ring portion 040 refer to positions, and are not limited to a split structure. The inner ring portion 030 is located at the inner periphery of the outer ring portion 040. The inner ring part 030 of the profile frame 100 forms a non-strong connection in the thickness direction, and has a sealing strip 400 and a sound-absorbing filler to assist in achieving a sound insulation effect. The total thickness of each inner ring wall structure 131 in the thickness direction of the inner ring part 030 can be relatively small, specifically limited to greater than 6 mm, to provide a basic sound insulation effect. In a specific implementation process, the total thickness of the inner ring wall structure 131 is 6 mm, which can provide a basic sound insulation effect under the premise of meeting the structural strength. The outer ring part 040 of the profile frame 100 forms a relatively strong connection in the thickness direction, and a tubular cavity is respectively provided in the thickness direction of the outer ring part 040 corresponding to the first profile tube frame 110 and the second profile tube frame 120, thereby forming a relatively strong sound insulation and heat insulation effect. In the prior art, there is no targeted consideration for the wall thickness of the wall structure on the profile, and it is basically set to the same wall thickness, so the resonance effect can be generated, thereby reducing the sound insulation effect of the profile frame 100 in the thickness direction at the position of the outer ring part 040. In the present invention, first, the profile frame 100 is provided with at least four outer ring wall structures 141 in the thickness direction at the position of the outer ring portion 040, and the total thickness of the outer ring wall structure 141 is greater than 10 mm and i / n ≥ 50%, (a i -a i-1 ) / a i-1≥5%, while ensuring the overall sound insulation effect, the resonance effect is weakened. For example, if there are four outer ring wall structures 141, then from the thin size to the thick size, at most only three outer ring wall structures 141 can form an increase in thickness, and at least 50% of the outer ring wall structures 141 form an increment in thickness, so at least three different thickness dimension values ​​are formed in the four outer ring wall structures 141. In the present invention, since there is no restriction on the difference between all outer ring wall structures 141, if the thinnest outer ring wall structure 141 is used as the basis for the size increment, the increment percentage range is large and cannot be appropriately limited; therefore, it is limited to the outer ring wall structure 141 with a corresponding increment relative to the previous thickness dimension. Specifically, in the case of a lower thickness dimension, the percentage increase in the thickness dimension can be larger, and in the case of a larger thickness dimension, the percentage increase in the thickness dimension needs to be smaller. It is particularly noted that the size increment of each outer ring wall structure 141 from thin to thick in the thickness direction of the outer ring portion 040 does not refer to the outer ring wall structures 141 arranged sequentially in the thickness direction having an increasing thickness size, but the thickness size of the outer ring wall structure 141 has an increment after being arranged from thin to thick. The thickness direction of the inner ring wall structure 131 and the outer ring wall structure 141 perpendicular to the profile frame 100 refers to the trend. In this embodiment, Figure 5 A vertical dotted line is drawn with the tubular cavity as the boundary, the right side of the dotted line is the inner ring portion 030, and the left side of the dotted line is the outer ring portion 040. The division of the inner ring portion and the outer ring portion in this embodiment is only for illustration.

[0061] The polymer connector 200 connects the first profile tube frame 110 and the second profile tube frame 120 in the thickness direction of the profile frame 100. The polymer connector 200 may include a plurality of rubber strips 210 arranged to form a frame shape, and there is not limited to only one rubber strip 210 on each side of the profile frame 100, that is, the polymer connector 200 is not limited to a single-layer ring. The material of the polymer connector 200 is made of at least one of PVC, rubber, silicone or nylon, and has suitable structural strength and weather resistance. According to the specific conditions of use, it can also be selected from the above several preferred materials. It should be noted that even if the type of material of the polymer connector 200 is selected, performance differences can be formed according to different process selections, and the process selection is also optimized according to the actual use conditions. The polymer connector 200 is preferably connected by clamping in the way of connecting the first profile tube frame 110 and the second profile tube frame 120.

[0062] The glass panel part 300 is arranged in the middle of the plane of the soundproof window and is clamped by the first profile tube frame 110 and the second profile tube frame 120. A sealing strip 400 may be arranged at the contact position between the glass panel part 300 and the profile frame 100 in the thickness direction. The sealing strip 400 is made of at least one of EPDM rubber, thermoplastic elastomer or silicone rubber. The specific structure of the glass panel part 300 may be various, and may be a solid structure (such as glass of various materials); or may be a component structure, such as forming a multi-layer composite structure, so as to enhance the heat insulation and sound insulation effect. The thickness and other characteristics of the glass panel part 300 have a great influence on the heat insulation and sound insulation effect of the entire soundproof window.

[0063] In summary, the total thickness of each inner ring wall structure 131 of the inner ring part 030 of the profile frame 100 in the thickness direction is greater than 6 mm, providing a basic sound insulation effect. The outer ring part 040 of the profile frame 100 forms two tubular cavities in the thickness direction. The profile frame 100 is provided with at least four outer ring wall structures 141 in the thickness direction at the position of the outer ring part 040. The total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is increased to greater than 10 mm. The n outer ring wall structures have i thickness sizes, n≥4, i≥2; the i thickness sizes are arranged from thin to thick as a1, a2...a i , then i / n≥50% and (a i -a i-1 ) / a i-1 ≥5%; while ensuring the overall sound insulation effect (especially in the low-frequency range), the resonance effect is weakened to improve the low-frequency sound insulation performance.

[0064] Reference Figure 5 In one embodiment, the thicknesses of the inner ring wall structures 131 of the inner ring portion 030 in the thickness direction are different, and the total thickness of the inner ring wall structures 131 of the inner ring portion 030 in the thickness direction is 10 mm to 16 mm.

[0065] In the present invention, considering that the outer ring portion 040 of the profile frame 100 forms a stronger connection in the thickness direction, the size a of each outer ring wall structure 141 in the thickness direction is set to i Satisfy (a i -a i-1 ) / a i-1≥5%, in order to reduce the resonance effect; and the inner ring part 030 of the profile frame 100 forms a connection in the thickness direction that is not a strong connection (with a sealing strip 400 and a sound-absorbing filler), so the thickness characteristics of each inner ring wall structure 131 of the inner ring part 030 in the thickness direction are not limited. However, in this embodiment, the thickness of each inner ring wall structure 131 of the inner ring part 030 in the thickness direction is formed differently with reference to the outer ring part 040, which can also reduce the vibration (noise) transmitted by resonance on the inner ring part 030 to a certain extent, thereby improving a certain sound insulation effect. The thickness difference of each inner ring wall structure 131 of the inner ring part 030 in the thickness direction is not limited. The number of inner ring wall structures 131 of the inner ring part 030 is small and some are not used as the structural basis, so the thickness dimensions of different inner ring wall structures 131 may differ greatly. Preferably, the inner ring wall structure 131 can have an increment of 10% to 100% from the thin size to the thick size. The total thickness of each inner ring wall structure 131 in the thickness direction of the inner ring portion 030 is limited to 10 mm to 16 mm, thereby ensuring the basic sound insulation effect. Those skilled in the art can use the teachings disclosed herein to seek to obtain the desired properties and appropriately change these approximate values. The use of numerical ranges expressed as endpoints includes all numbers within the range and any range within the range.

[0066] In one embodiment, i / n≥50% and 5%≤(a i -a i-1 ) / a i-1 ≤50%.

[0067] In this embodiment, the thickness increment of the outer ring wall structure 141 is further limited to 5%≤(a i -a i-1 ) / a i-1 ≤50%, in order to weaken the resonance effect and facilitate processing.

[0068] In one embodiment, i=n, ​​and 10 mm≤a1+a2+...+a n ≤16mm.

[0069] In this embodiment, the total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is limited to 10mm to 16mm; the total thickness of each inner ring wall structure 131 in the thickness direction of the inner ring part 030 is 10mm to 16mm; the above two total thickness limits can meet the application requirements of most conditions while meeting the most basic sound insulation requirements, and will not cause waste of materials. In the specific implementation process, the total thickness of the outer ring part 040 in the thickness direction is 12mm, and the total thickness of each inner ring wall structure 131 in the thickness direction of the inner ring part 030 is 10mm. Those skilled in the art can use the teachings disclosed in this article to seek to obtain the desired characteristics and appropriately change these approximate values. The use of a numerical range represented by an endpoint includes all numbers in the range and any range in the range.

[0070] In one embodiment, i=n, ​​and 5%≤(a i -a i-1 ) / a i-1 ≤50%.

[0071] In this embodiment, all the outer ring wall structures 141 have thickness differences, so the effect of weakening the resonance effect is optimal.

[0072] In one embodiment, along the thickness direction of the profile frame 100 , the thicknesses of at least two layers of the outer ring wall structures 141 in any four adjacent layers of the n outer ring wall structures are not equal.

[0073] In this embodiment, in some cases, the number of outer ring wall structures 141 is large. In addition to limiting i / n ≥ 50% and (a i -a i-1 ) / a i-1 ≥5%, and at least two layers of outer ring wall structures 141 in any adjacent four layers of outer ring wall structures 141 are further restricted to be unequal in thickness, thereby ensuring that the resonance effect is weakened while not increasing the difficulty of design and processing. For example, there are six layers of outer ring wall structures 141, and the outermost two layers of outer ring wall structures 141 are relatively thin and mainly play an appearance effect, and are designed to be thinner and have the same thickness, while the remaining four layers of outer ring wall structures 141 have different thicknesses from each other.

[0074] In one embodiment, along the thickness direction of the profile frame 100, 120%≤a i / a1≤500%.

[0075] In the present embodiment, the thickness difference range between the thinnest and thickest outer ring wall structures 141 is provided. When the number of layers of the outer ring wall structure 141 is large, the difference between the thinnest and thickest outer ring wall structures 141 is large and closer to the upper limit of 500%; when the number of layers of the outer ring wall structure 141 is small, the difference between the thinnest and thickest outer ring wall structures 141 is small and closer to the upper limit of 120%. When the thickness difference between the thinnest and thickest outer ring wall structures 141 falls outside the above range, it is disadvantageous for the convenience of processing and the control of cost.

[0076] In one embodiment, the soundproof window with optimized low-frequency noise processing also includes a sound-absorbing filler, which includes a first sound-absorbing filler 510 and a second sound-absorbing filler 520. The first sound-absorbing filler 510 is compressed and clamped between a first side of the glass panel portion 300 in a thickness direction and an inner wall of the inner ring portion 030; the second sound-absorbing filler 520 is compressed and clamped between a second side of the glass panel portion 300 in a thickness direction and an inner wall of the inner ring portion 030.

[0077] In this embodiment, the sound-absorbing filler includes a first sound-absorbing filler 510 and a second sound-absorbing filler 520, and the first sound-absorbing filler 510 and the second sound-absorbing filler 520 are respectively compressed and clamped between the first side and the second side of the thickness direction of the glass panel part 300 and the inner wall of the inner ring part 030. Thus, high-quality heat insulation and sound insulation effects are formed at the joint position of the glass panel part 300. The first sound-absorbing filler 510 includes a plurality of sound-absorbing cotton strips arranged to form a frame, or can be filled with flocculent sound-absorbing cotton. The second sound-absorbing filler 520 includes a plurality of sound-absorbing cotton strips arranged to form a frame, or can be filled with flocculent sound-absorbing cotton. By compressing and filling the sound-absorbing filler, the elastic force provided by the sound-absorbing filler can tighten the combination between the surrounding components, thereby reducing the generation of abnormal vibration. Sound-absorbing cotton is usually composed of a variety of fiber materials, which have good sound absorption performance. The specific sound-absorbing cotton material may vary depending on the brand, product type and purpose, but common materials include glass fiber, mineral wool, polyester fiber, etc. These materials have excellent sound absorption performance and durability, and can effectively absorb and reduce the reflection and propagation of sound. The first sound absorbing filler 510 and the second sound absorbing filler 520 are respectively compressed and clamped between the first side and the second side of the thickness direction of the glass panel part 300 and the inner wall of the inner ring part 030, thereby forming a high-quality heat insulation and sound insulation effect at the joint position of the glass panel part 300; by compressing and filling the sound absorbing filler, the elastic force provided by the sound absorbing filler can tighten the joints between the surrounding components, thereby reducing the generation of abnormal vibrations; through the above triple settings, while having an overall high-quality sound insulation performance, it also achieves excellent sound insulation effect at low-frequency positions.

[0078] In one embodiment, the sound-absorbing filler has an installation density of 8 kg / m3 to 12 kg / m3 and is made of organic sound-absorbing cotton.

[0079] In this embodiment, in order to improve the absorption effect of low-frequency noise, the density of the sound-absorbing filler installed (i.e., the density after compression) is limited and increased. In the final performance test results, the superior sound insulation effect of the product under low-frequency conditions is also demonstrated. Organic sound-absorbing cotton can provide a relatively superior porosity while being easy to install, and its low density makes it more sensitive to the effects of low-frequency noise, thereby providing excellent low-frequency acoustic effects. Depending on the actual usage scenario, the installation density of the sound-absorbing filler can be a value between 8 kilograms per cubic meter and 12 kilograms per cubic meter.

[0080] In one embodiment, the compression rate of the sound absorbing filler is between 30% and 80%.

[0081] In this embodiment, the density of the basic sound-absorbing filler is increased by compression. During the compression process, the overall density is increased to optimize the low-frequency sound absorption effect. At the same time, the sound-absorbing filler provides elastic force, and the elastic force is directed in all directions, so that the components are more tightly combined. The compression rate of the sound-absorbing filler is between 30% and 80%, and the compression rate needs to be moderate to provide excellent acoustic and mechanical properties. The compression rate is calculated as the ratio between the difference obtained by subtracting the compressed volume from the initial volume and the initial volume. The compression rate of the sound-absorbing filler is preferably between 60% and 70%. The superiority shown in the experimental results is inferred that when the sound-absorbing filler is compressed, the structure between the various parts of itself has a certain instability, so the possibility of friction and vibration between the various structures is reduced, so the compression characteristics of the sound-absorbing filler also have a positive effect on the improvement of acoustic performance.

[0082] In one embodiment, the first sound absorbing filler 510 and the second sound absorbing filler 520 are an integral structure in the thickness direction of the profile frame 100 , and the periphery of the glass panel portion 300 and the polymer connector 200 clamp a portion of the sound absorbing filler.

[0083] In this embodiment, the first sound absorbing filler 510 and the second sound absorbing filler 520 are set as an integral structure in the thickness direction of the profile frame 100, so that the production process and the installation process are convenient. It should be noted that, for the purpose of installation, the sound absorbing filler is not limited to be continuous in the circumferential direction. In the implementation process, the initial state shape of the sound absorbing filler needs to be subject to certain restrictions (for example, the inner peripheral wall is provided with a groove), so as to facilitate the installation of the glass panel part 300. When the first sound absorbing filler 510 and the second sound absorbing filler 520 are an integral structure in the thickness direction of the profile frame 100, the sound absorbing filler can simultaneously buffer the periphery of the glass panel part 300. At this time, the periphery of the glass panel part 300 and the polymer connector 200 clamp part of the sound absorbing filler.

[0084] Reference Figures 6 to 7 In one embodiment, the glass panel portion 300 includes a plurality of stacked glass panels 310 , and adjacent glass panels 310 are sandwiched with a support matrix 320 in a thickness direction and form a negative pressure cavity 330 .

[0085] In the aforementioned embodiment, the glass panel portion 300 may be a solid structure (such as a single layer of glass of various materials). In the present embodiment, the glass panel portion 300 of the vacuum glass type is used to suppress the noise transmission and heat transfer of the glass panel portion 300 in the thickness direction. Specifically, the thickness of the glass panel 310 and the thickness of the negative pressure cavity 330 are selected according to the actual application and are not limited here. For vacuum glass, when the glass panel 310 is subjected to atmospheric pressure, the two parallel adjacent glass panels 310 will be moved inward, which will affect the structure of the glass panel 310 and is also not conducive to the maintenance of the negative pressure cavity 330. In order to ensure the functionality of the negative pressure cavity 330, a support matrix 320 is placed between the two layers of glass panels 310, and the support matrix 320 is composed of support points 321 arranged. The specific setting of the support matrix 320 needs to minimize the volume and total number of the support matrix 320 to avoid increasing the thermal conductivity and reducing the transparency of the glass; if the volume of the support matrix 320 is too small, a concentrated load will be formed at the part. Due to the effect of atmospheric pressure, the stress between the glass panel 310 and the support matrix 320 will increase, and the risk of the glass panel 310 breaking will increase; the shape of the support points 321 is currently the most common cylindrical, and there are also square or elliptical shapes; the material of the support points 321 can be stainless steel, tungsten carbide steel, chrome steel, aluminum alloy, nickel, lead, tantalum, ceramics, etc. The support points 321 can use plastically deformable, linear, lattice-shaped supports, or use thin metal wires to connect the support points 321 to each other, which can reduce the possibility of damage to the glass panel 310. The thickness of the multi-layer glass panels 310 is different from each other. By making the thickness of the multi-layer glass panels 310 inconsistent, the noise transmitted by the resonance effect between the glass panels 310 is reduced. A difference of 15% to 30% is formed between the multi-layer glass panels 310. For example, the total number of layers of the glass panel 310 is two, which are 6 mm and 8 mm respectively; or the total number of layers of the glass panel 310 is three, which are 6 mm, 8 mm and 10 mm respectively.

[0086] Reference Figure 7 In one embodiment, the support matrix 320 includes support points 321 arranged in a rectangular array.

[0087] In this embodiment, the support points 321 are arranged in a rectangular array, which has the advantages of simple processing and regular arrangement. The specific dimensions of the rectangular array in two directions can be 20 mm and 30 mm respectively. The dimensions of the rectangular array can be adaptively adjusted according to the actual usage scenario.

[0088] Reference Figure 8In one embodiment, the glass panel portion 300 is rectangular, the support point matrix 320 includes multiple layers of support circle arrays 322 arranged layer by layer, the support circle array 322 includes multiple support points 321 and is arranged in a rectangular circle, and the interval between adjacent support circle arrays 322 on the plane of the glass panel portion 300 increases as the position decreases toward the center of the glass panel portion 300;

[0089] In which, on each side of the pillar circle array 322 , the interval between adjacent pillar dot arrays 320 has a tendency to decrease toward the angular position of the glass panel portion 300 .

[0090] The current pillar lattice 320 is generally arranged in the form of a uniform lattice, and is connected to the glass panel 310 in a rigid manner. Then the pillar lattice 320 separates the glass panel portion 300 into a plurality of regular substructures. The sound waves in a specific frequency band in the noise have a probability of causing the plurality of substructures to form a resonance effect, which has a negative impact on the sound insulation effect. In this embodiment, the pillar lattice 320 is arranged in a non-uniform manner, and specifically the pillar lattice 320 is adapted to the plane shape of the glass panel portion 300 and divided into a plurality of pillar circle arrays 322. The interval between the adjacent pillar circle arrays 322 on the plane increases as the position decreases toward the center of the glass panel portion 300. Then, in the direction toward the center of the glass panel portion 300, the pillar lattice 320 no longer separates the glass panel 310 into regular substructures. On each side of the pillar circle array 322, the interval between the adjacent pillar lattices 320 has a tendency to decrease as it approaches the angular position of the glass panel portion 300. Then, in the circumferential direction, the pillar lattice 320 no longer separates the glass panel 310 into regular substructures. Through the above two settings, the substructures divided by the pillar lattice 320 on the plane of the entire glass panel 310 form a very large unevenness, which greatly reduces the generation of the resonance effect. At the same time, the above setting from outside to inside, from dense to sparse, is also beneficial to the use effect. Specifically, the glass panels 310 are generally combined through the outer circle of the adhesive ring, so the pillar points 321 near the adhesive ring (especially at the corner position) are more important, and in the middle of the glass panel 310, in order to optimize the field of view, the existence of the pillar points 321 will have a negative impact. Therefore, the setting of the pillar lattice 320 from outside to inside, from dense to sparse can assist in optimizing the structural characteristics of the adhesive ring and provide convenience for the optimization of the field of view in the middle of the glass panel 310. In summary, the restrictions on the arrangement rules of the pillar lattice 320, while weakening the resonance effect, ensure the structural stability of the glass panel part 300 and the field of view in the middle. In a specific implementation process, the degree of increase in the spacing between the pillar arrays 322 and the spacing between the pillar points 321 on the pillar array 322 can be set in a specific value, percentage, or in accordance with other systems (exponential curves, etc.). For example, the spacing of the outermost part is 20 mm, and the inner circle of the pillar array 322 is set in increments of 5 mm. For example, on each side of the pillar array 322, starting from the closest corner position on each side and moving toward the middle of each side, the spacing between the pillar points 321 increases at an incremental rate of 20%.

[0091] In one embodiment, the polymer connector 200 is in a tensile stress state in the thickness direction of the soundproof window.

[0092] At present, the state of the polymer connector 200 is not limited. The polymer connector 200 connects the first profile tube frame 110 and the second profile tube frame 120 in a free state in the thickness direction (in order to reduce the vibration and heat transfer between the first profile tube frame 110 and the second profile tube frame 120, the strong structural connection between the two should be as few as possible or even absent). Since the polymer connector 200 is in a free state, there are certain hidden dangers in the structural strength of the profile frame 100 in the thickness direction (it is easier to deform). Therefore, in this embodiment, since the first sound-absorbing filler 510 and the second sound-absorbing filler 520 are both in a compressed state, the first profile tube frame 110 and the second profile tube frame 120 have a tendency to separate under the elastic force of the sound-absorbing filler. At this time, as long as the length of the polymer connector 200 is limited in the thickness direction of the profile frame 100, the polymer connector 200 can be in a tensile stress state in the thickness direction of the window frame through the action of the sound-absorbing filler. Through the above arrangement, the possibility of dimensional changes occurring when the soundproof windows are subjected to pressure or tension in the thickness direction during production, storage, transfer and use is reduced.

[0093] Reference Figure 5 In one embodiment, there are multiple polymer connectors 200, which are spaced apart in the width direction thereof, and the multiple polymer connectors 200 are respectively clipped onto the first profile tube frame 110 and the second profile tube frame 120 at both ends of the profile frame 100 in the thickness direction.

[0094] In this embodiment, the number of polymer connectors 200 is increased to two, and they are spaced apart in the width direction, so that two ring structures are formed. The connection method of the polymer connector 200 with the first profile tube frame 110 and the second profile tube frame 120 is preferably a convenient, stable and reliable clamping. When multiple polymer connectors 200 are provided, after a single polymer connector 200 partially fails, the connection effect between the first profile tube frame 110 and the second profile tube frame 120 is maintained, and the chamber structure formed between the polymer connectors 200 can improve the heat insulation and shock absorption effects.

[0095] In one embodiment, the dimension of the polymer connector 200 in the thickness direction of the profile frame 100 is 25 mm to 30 mm, and the dimension of the soundproof window in the thickness direction is greater than 80 mm.

[0096] In this embodiment, the size of the polymer connector 200 in the thickness direction of the profile frame 100 is increased, and then the total thickness size of the soundproof window is also increased. By increasing the thickness of the polymer connector 200, the vibration transmission between the first profile tube frame 110 and the second profile tube frame 120 is weakened. When the polymer connector 200 has an inner cavity, the thickness of the inner cavity is also increased along with the thickness of the polymer connector 200, which is beneficial for both heat insulation and sound insulation. The total thickness of the soundproof window is also increased, so the thickness size of the cavity in the first profile tube frame 110 and the second profile tube frame 120 is also increased, which also improves the heat insulation and sound insulation effects. In actual production scenarios, the dimension of the polymer connector 200 in the thickness direction of the profile frame 100 can be 25mm to 30mm, as well as various intermediate values ​​(such as 26mm, 27mm, 28mm, etc.); in the specific implementation process, the dimension of the polymer connector 200 in the thickness direction of the profile frame 100 is preferably 27mm, so that while the structural strength can be maintained, a relatively superior heat insulation and shock absorption effect can be achieved.

[0097] Embodiment 1:

[0098] The profile frame 100 is made of aluminum alloy. The total thickness of each inner ring wall structure 131 of the inner ring part 030 of the profile frame 100 along the thickness direction is 8mm. The total thickness of each outer ring wall structure 141 of the outer ring part 040 along the thickness direction is 12mm. In the direction from the first side of the thickness to the second side of the thickness direction, the thickness of the outer ring wall structure 141 is 2mm, 4.4mm, 1.8mm and 3.8mm respectively. A tubular cavity is respectively arranged in the thickness direction of the outer ring part 040 corresponding to the first profile tube frame 110 and the second profile tube frame 120. The material of the polymer connector 200 is PVC, and the size in the thickness direction of the profile frame 100 is 25mm. The glass panel part 300 is arranged in the middle of the plane of the soundproof window and is clamped by the first profile tube frame 110 and the second profile tube frame 120. The glass panel part 300 is double-layer vacuum glass (the thickness of the glass panel 310 is 6 mm and 8 mm respectively, and the thickness of the negative pressure chamber 330 is 8 mm), and the pillar matrix 320 is arranged in a rectangular array of 50 mm by 50 mm. The contact position of the glass panel part 300 in the thickness direction with the profile frame 100 can be provided with an EPDM rubber sealing strip 400. The initial density of the first sound-absorbing filler 510 and the second sound-absorbing filler 520 is 8 kg per cubic meter, and the final compression ratio is 50%.

[0099] Reference Fig. 9 , the weighted sound insulation performance test was carried out on the above, the Rw sound insulation value was 44, and the two correction values ​​were 0 and 1 respectively, showing its superior sound insulation performance, especially in the low-frequency range, the sound insulation value exceeded 40 decibels, showing excellent low-frequency performance.

[0100] Embodiment 2:

[0101] The difference from Example 1 is that the support matrix 320 is arranged as a multi-layer support circle array 322, with an initial spacing of 20 mm, and then increasing by 10 mm. The spacing between adjacent support circle arrays 322 on the plane increases as the position decreases toward the center of the glass panel portion 300.

[0102] Reference Fig.10 , the weighted sound insulation performance test of the above is carried out, and the Rw sound insulation value is 44, and the two correction values ​​are 0 and 1 respectively, which shows its excellent sound insulation performance. Especially in the low frequency range, its sound insulation performance continues to be slightly improved on the basis of the excellent performance of Example 1.

[0103] Comparative Example 1:

[0104] The difference from Example 1 is that the total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is 12 mm, and is 3 mm.

[0105] Reference Fig.11 The above-mentioned sound insulation performance was tested, and the Rw sound insulation value was 38. Especially in the low-frequency range, the sound insulation performance was relatively inferior to that of Example 1 and Example 2.

[0106] Embodiment 3:

[0107] The difference from Example 1 is that the total thickness of each inner ring wall structure 131 in the thickness direction of the inner ring portion 030 is 6 mm, which can provide basic sound insulation effect while meeting the structural strength. The above minimum value of the total thickness of 6 mm is the minimum acceptable value verified during the experiment.

[0108] Embodiment 4:

[0109] The difference from Example 1 is that the total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is 10 mm. Under the premise of satisfying the structural strength, the total thickness restriction can provide the sound insulation effect that meets the standard, and can provide space for the wall thickness difference gradient to verify the acceptable minimum value during the experiment. In other embodiments, the total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is 16 mm, which also proves that it can meet the application in most use scenarios. Of course, as the overall thickness value continues to increase, the sound insulation effect will also be slightly improved.

[0110] Embodiment 5:

[0111] The difference from Example 1 is that the thickness of the outer wall structure 141 is 3mm, 4.62mm, 2mm and 4.4mm respectively. Then, from the thin size to the thick size, the outer wall structure 141 has an increment of 50%, 46.6% and 5% respectively compared with the outer wall structure 141 of the previous thickness size.

[0112] The present invention also provides an installation method, which is applied to the above-mentioned soundproof window with optimized low-frequency noise processing, including:

[0113] S1, installing the polymer connector 200 on the first profile pipe frame 110;

[0114] S2, installing the first sound-absorbing filler 510 on the first profile tube frame 110;

[0115] S3, installing the glass panel portion 300 on the first profile tube frame 110;

[0116] S4, installing the second sound-absorbing filler 520 on the inner circumferential wall of the polymer connector 200;

[0117] S5. Install the second profile pipe frame 120 on the polymer connector 200 .

[0118] In step S1 , for example, the polymer connector 200 includes a plurality of rubber strips 210 arranged to form a frame, and the plurality of rubber strips 210 are respectively connected to the first side profile tube 111 and the second side profile tube 121 , thereby installing the polymer connector 200 on the first profile tube frame 110 .

[0119] In step S2 , for example, the first sound-absorbing filler 510 includes a plurality of sound-absorbing cotton strips arranged to form a frame shape, and the plurality of sound-absorbing cotton strips are installed on the first profile tube frame 110 to form the first sound-absorbing filler 510 .

[0120] In step S3 , the glass panel portion 300 is installed on the first profile tube frame 110 . During this process, the first sound absorbing filler 510 is compressed to a certain extent.

[0121] In step S4 , for example, the second sound absorbing filler 520 includes a plurality of sound absorbing cotton strips arranged to form a frame shape, and the plurality of sound absorbing cotton strips are installed on the inner peripheral wall of the polymer connector 200 to form the second sound absorbing filler 520 .

[0122] In step S5, the second profile tube frame 120 is installed on the polymer connector 200, and the installation of the soundproof window is completed. In this process, the second sound-absorbing filler 520 and the first sound-absorbing filler 510 are compressed in place. By adjusting the filling state of the second sound-absorbing filler 520 and the first sound-absorbing filler 510, the polymer connector 200 can also be in a tensile stress state in the thickness direction of the soundproof window. By setting the installation condition of the tensile stress state, the possibility of dimensional change of the soundproof window when it is subjected to pressure or tensile stress in the thickness direction is reduced.

[0123] In one embodiment, step S0 is performed before step S1:

[0124] The first profile tube frame 110 and the second profile tube frame 120 are assembled respectively.

[0125] In this embodiment, in step S0, for example, the first profile tube frame 110 includes a plurality of first side profile tubes 111 and a first angle code piece connecting the plurality of first side profile tubes 111 end to end, and the second profile tube frame 120 includes a plurality of second side profile tubes 121 and a second angle code piece connecting the plurality of second side profile tubes 121 end to end. The first profile tube frame 110 and the second profile tube frame 120 are assembled. During the assembly process of the first profile tube frame 110 and the second profile tube frame 120, it is suggested to connect the sealing strip 400 to the corresponding positions of the first profile tube frame 110 and the second profile tube frame 120 in advance.

[0126] Compared with the current soundproof window, each frame is independently installed and formed, and then installed with the glass panel part 300. If the above process is copied, the first sound-absorbing filler 510 and the second sound-absorbing filler 520 need to be in a compressed state after the installation (especially when the compression degree is high). Therefore, the traditional insertion method cannot smoothly complete the installation process. In addition, the installation process of the current form of independent installation of each frame is relatively trivial and has poor continuity. The installation method in this embodiment has high continuity and modularity.

[0127] In summary, the present invention provides a soundproof window with optimized low-frequency noise processing and an installation method thereof. The total thickness of each inner ring wall structure 131 of the inner ring part 030 of the profile frame 100 in the thickness direction is greater than 6 mm, providing a basic sound insulation effect. The outer ring part 040 of the profile frame 100 forms two tubular cavities in the thickness direction. The profile frame 100 is provided with at least four outer ring wall structures 141 in the thickness direction at the position of the outer ring part 040. The total thickness of each outer ring wall structure 141 in the thickness direction of the outer ring part 040 is increased to greater than 10 mm and 5% ≤ (a i -a i-1 ) / a i-1≤50%, while ensuring the overall sound insulation effect (especially in the low-frequency range), the resonance effect is weakened to improve the low-frequency sound insulation performance.

[0128] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
