Description

Technical Field

[0001] This application relates to the field of home decoration technology, and in particular to a silent joint filling structure for prefabricated movable walls in interior spaces. Background Technology

[0002] In the field of prefabricated decoration, movable walls (or movable furniture that also functions as walls) are widely used because they can flexibly divide interior spaces. When designing these movable walls, to meet their movement requirements such as translation and rotation, a certain gap (usually 5mm to 10mm) must be left between them and the fixed side walls, floor, or ceiling to avoid friction and collision with surrounding structures during movement. However, once the movable wall is in place and fixed, the aforementioned gaps cannot be effectively filled, causing airborne sound (such as conversations, equipment operation noise, etc.) from adjacent spaces to propagate through the gaps, creating significant noise interference and seriously affecting the privacy and comfort of the space.

[0003] In related technologies, recessed dust-blocking strips or sound-insulating strips are commonly used. Taking dust-blocking strips as an example, through the linkage design between the door closer and the dust-blocking strip, the strip sinks down to fill the gap under the door when the door is closed, which can play a certain role in sound insulation and dust blocking. However, the sound insulation material of such products is limited and can only cover the area under the door, failing to solve the problem of sound leakage from the gaps on the sides, top, and bottom of movable walls. Insufficient airtightness results in limited sound insulation effect. In addition, sound-insulating strips often need to be installed on the outside of the door panel or the surface of the wall, which not only destroys the overall decorative effect of the movable wall but may also hinder the movement of the wall due to protruding from the surface, making it difficult to balance functionality and aesthetics. Summary of the Invention

[0004] Therefore, it is necessary to provide a silent joint filling structure for prefabricated indoor space movable walls, which addresses the problem that existing movable walls cannot simultaneously achieve ease of movement, aesthetics, and sound insulation.

[0005] A silent joint-filling structure for prefabricated movable walls in interior spaces is applied to a fixed surface and a movable wall movably connected to the fixed surface, wherein a gap exists between the fixed surface and the movable wall; the movable wall is constructed with an installation groove; the silent joint-filling structure for prefabricated movable walls in interior spaces includes:

[0006] The sound insulation unit includes an inflatable component and multiple sound insulation components. The inflatable component is connected to the wall of the mounting groove. The multiple sound insulation components are connected to the outside of the inflatable component and are distributed at intervals along the circumference of the inflatable component.

[0007] When the sound insulation unit is in a non-working state, the inflatable component is in a retracted state, and the sound insulation unit is located in the mounting groove;

[0008] When the sound insulation unit is in working condition, the inflatable component is in an expanded state, the sound insulation unit fills the gap, and the sound insulation unit abuts against the fixed surface.

[0009] In one embodiment, the sound insulation component includes an aluminum foil composite film, a porous polyurethane foam, and a melamine sound insulation pad arranged sequentially.

[0010] The porous polyurethane foam covers the outside of the aluminum foil composite film; the melamine sound insulation pad covers the outside of the porous polyurethane foam.

[0011] In one embodiment, the prefabricated indoor space movable wall silent caulking structure includes an air pump and an inflation pipe connecting the air pump and the inflation component.

[0012] In one embodiment, the prefabricated indoor space movable wall with a silent joint filling structure includes an exhaust pipe with an exhaust valve connected to it.

[0013] In one embodiment, the prefabricated indoor space movable wall silent caulking structure includes a controller and a monitoring unit, wherein the controller is used to adjust the working state of the air pump according to the parameter values ​​detected by the monitoring unit.

[0014] In one embodiment, the monitoring unit includes a pressure detection module for collecting the air pressure value of the inflatable component;

[0015] The controller has a preset air pressure standard threshold. When the air pressure value collected by the pressure detection module reaches the air pressure standard threshold, the controller controls the air pump to stop working. When the air pressure value is lower than the air pressure standard threshold, the controller controls the air pump to inflate and pressurize the inflation component.

[0016] In one embodiment, the controller further presets a pressure safety threshold; the ratio of the pressure safety threshold to the pressure standard threshold is 1.5 to 2 times.

[0017] When the pressure detection module detects that the air pressure of the inflation component exceeds the air pressure safety threshold, the controller controls the air pump to stop inflation.

[0018] In one embodiment, the monitoring unit includes an environmental noise monitoring module, which is used to collect noise decibel values ​​of adjacent spaces and transmit them to the controller;

[0019] The controller has a preset noise threshold. When the noise decibel value collected by the environmental noise monitoring module exceeds the noise threshold, the controller controls the air pump to inflate and pressurize the inflatable component so that the air pressure of the inflatable component is increased to a preset enhancement value. When the noise decibel value is lower than or equal to the noise threshold, the controller controls the air pressure of the inflatable component to be maintained at a standard value.

[0020] In one embodiment, the inflatable component includes a rubber liner, a metal mesh frame, and a damping coating arranged sequentially; the metal mesh frame is embedded on the outside of the rubber liner, and the damping coating covers the outside of the metal mesh frame.

[0021] In one embodiment, the wall of the mounting groove and the inflatable component are respectively provided with a first magnetic chuck and a second magnetic chuck; the first magnetic chuck and the second magnetic chuck cooperate to fix the inflatable component to the mounting groove.

[0022] The aforementioned prefabricated movable wall system for indoor spaces utilizes a silent gap-filling structure. When the inflatable component is in its retracted state, the sound insulation unit is completely housed within the mounting groove of the movable wall, not protruding from the wall surface. This ensures that the pre-reserved gap between the movable wall and the fixed surface remains unobstructed during translation, rotation, and other movements, meeting the flexible adjustment requirements of the movable wall. Once the movable wall is in place and fixed, the inflatable component expands, filling the gap and tightly abutting against the fixed surface. This physical seal blocks the airborne sound transmission path, balancing the needs of mobility with sound insulation. Simultaneously, the sound insulation unit employs a composite structure of inflatable and sound-insulating components. After expansion, the inflatable component elastically deforms and tightly adheres to the fixed surface, adapting to dimensional fluctuations in the gap caused by installation errors or slight wall deformation, ensuring airtightness. The outer sound insulation component further absorbs and blocks sound waves, forming a dual barrier of physical sealing and material sound insulation. Compared to a single dustproof or soundproof strip, this significantly improves the blocking effect against mid-to-high frequency noise. When the inflatable component retracts, meaning the sound insulation unit is in a non-working state, it can be completely hidden inside the mounting groove of the movable wall, with no exposed parts. When the inflatable component expands, meaning the sound insulation unit is in a working state, it contacts the fixed surface through the sound insulation component. The contact part can be designed to match the color or texture of the wall surface according to decorative requirements, avoiding the aesthetic damage caused by traditional sound insulation strips being installed on the outside of the door panel, and maintaining the integrity and decorative uniformity of the movable wall surface.

[0034] In the field of prefabricated decoration, movable walls (or movable furniture that also functions as walls) are widely used because they can flexibly divide interior spaces. When designing these movable walls, to meet their movement requirements such as translation and rotation, a certain gap (usually 5mm to 10mm) must be left between them and the fixed side walls, floor, or ceiling to avoid friction and collision with surrounding structures during movement. However, once the movable wall is in place and fixed, the aforementioned gaps cannot be effectively filled, causing airborne sound (such as conversations, equipment operation noise, etc.) from adjacent spaces to propagate through the gaps, creating significant noise interference and seriously affecting the privacy and comfort of the space.

[0035] In related technologies, recessed dust-blocking strips or sound-insulating strips are often used. Taking dust-blocking strips as an example, through the linkage design between the door closer and the dust-blocking strip, the strip sinks down to fill the gap under the door when the door is closed, which can play a certain role in sound insulation and dust blocking. The inventors of this application have found that the sound insulation materials of such products are limited and can only cover the area under the door, failing to solve the problem of sound leakage from the gaps on the sides, top, and bottom of movable walls. Insufficient airtightness results in limited sound insulation effect. In addition, sound-insulating strips often need to be installed on the outside of the door panel or the surface of the wall, which not only destroys the overall decorative effect of the movable wall, but may also hinder the movement of the wall due to protruding from the surface, making it difficult to balance functionality and aesthetics.

[0036] Based on this, one embodiment of this application provides a silent joint filling structure for prefabricated movable walls in indoor spaces, which can solve the above-mentioned technical problems. The silent joint filling structure for prefabricated movable walls in indoor spaces provided by one embodiment of this application will be described in detail below with reference to the accompanying drawings.

[0037] See Figures 1 to 3 As shown in the figure, an embodiment of this application provides a silent joint filling structure for a prefabricated indoor space movable wall 200, applied to a fixed surface 300 and a movable wall 200 movably connected to the fixed surface 300, with a gap between the fixed surface 300 and the movable wall 200; the movable wall 200 is constructed with an installation groove 210; the silent joint filling structure for the prefabricated indoor space movable wall 200 includes a sound insulation unit 100, the sound insulation unit 100 including an inflatable component 110 and multiple sound insulation components 120. The inflatable component 110 is connected to the wall of the mounting groove 210; multiple sound insulation components 120 are connected to the outside of the inflatable component 110 and are distributed at intervals along the circumference of the inflatable component 110; when the sound insulation unit 100 is in a non-working state, the inflatable component 110 is in a contracted state and the sound insulation unit 100 is located in the mounting groove 210; when the sound insulation unit 100 is in a working state, the inflatable component 110 is in an expanded state, the sound insulation unit 100 fills the gaps, and the sound insulation unit 100 abuts against the fixed surface 300.

[0038] Understandably, the fixed surface 300 can be the wall surface of the fixed wall 320, or the ground 310, or the top surface such as the ceiling. The sound insulation unit 100 can be installed on the side of the movable wall, that is, between the wall surface of the fixed wall 320 and the side of the movable wall; it can also be installed on the bottom surface of the movable wall, that is, between the ground 310 and the bottom surface of the movable wall 200; or it can be installed on the top surface of the movable wall, that is, between the ceiling and the top surface of the movable wall 200; of course, the sound insulation unit 100 can also be installed on the side, bottom, and top surfaces of the movable wall 200, and correspondingly, the side, bottom, and top surfaces of the movable wall are all provided with mounting grooves 210 for installing the sound insulation unit 100.

[0039] The aforementioned prefabricated indoor movable wall 200 uses a silent gap-filling structure. When the inflatable component 110 is in the contracted state, the sound insulation unit 100 is completely housed within the mounting groove 210 of the movable wall 200, without protruding from the wall surface. This ensures that the reserved gap between the movable wall 200 and the fixed surface 300 is not obstructed during the movement, rotation, and other activities of the movable wall 200, thus meeting the flexible adjustment requirements of the movable wall 200. When the movable wall 200 is in place and fixed, the inflatable component 110 expands, causing the sound insulation unit 100 to fill the gap and tightly abut against the fixed surface 300. This physical seal blocks the airborne sound transmission path, thus balancing the needs of mobility and sound insulation. Meanwhile, the sound insulation unit 100 adopts a composite structure of an inflatable component 110 and a sound insulation component 120. After the inflatable component 110 expands, it fits tightly against the fixed surface 300 through elastic deformation, which can adapt to the size fluctuations of the gap caused by installation errors or slight deformation of the wall, ensuring airtightness. The outer sound insulation component 120 further absorbs and blocks sound waves, forming a double barrier of physical sealing and material sound insulation. Compared with a single dustproof strip or sound insulation strip, it significantly improves the blocking effect of mid-to-high frequency noise. When the inflatable component 110 contracts, that is, when the sound insulation unit 100 is in a non-working state, the sound insulation unit 100 can be completely hidden in the mounting groove 210 of the movable wall 200, with no exposed parts; when the inflatable component 110 expands, that is, when the sound insulation unit 100 is in a working state, it contacts the fixed surface 300 through the sound insulation component 120, and the contact part can be designed to match the color or texture of the wall surface according to the decoration requirements, avoiding the aesthetic damage caused by the traditional sound insulation strip being installed on the outside of the door panel, and maintaining the integrity and decorative uniformity of the surface of the movable wall 200.

[0040] In one embodiment, the sound insulation component 120 includes an aluminum foil composite film, a porous polyurethane foam, and a melamine sound insulation pad arranged sequentially; the porous polyurethane foam covers the outside of the aluminum foil composite film; and the melamine sound insulation pad covers the outside of the porous polyurethane foam.

[0041] In other words, the aluminum foil composite film is placed in the inner layer. The aluminum foil material has high density, reflecting over 70% of low-frequency sound waves (such as footsteps), reducing the energy transmitted into the inflatable component 110. Simultaneously, its airtightness blocks the direct path of sound transmission through the air, forming a dual barrier of physical isolation and reflection with the gas seal of the inflatable component 110. Porous polyurethane foam is placed in the middle layer, containing numerous interconnected pores with diameters ranging from 0.1mm to 1mm. It absorbs mid-to-high frequency sound waves (such as conversations and appliance noises) through air viscosity resistance and pore wall vibration, further attenuating residual sound waves that have passed through the aluminum foil composite film. Melamine sound insulation pads are placed in the outer layer. Their dense material and certain elasticity block high-frequency noise penetration through their density and allow for close contact with the fixed surface 300, filling in minor unevenness and reducing sound leakage due to gaps caused by loose adhesion, further improving overall airtightness. This three-layer structure forms a progressive acoustic treatment from three levels: reflection, absorption, and blocking, which significantly improves the sound insulation effect compared to a single sound insulation material.

[0042] Furthermore, both porous polyurethane foam and melamine sound insulation pads possess excellent elastic deformation capabilities, allowing them to deform synchronously with the expansion and contraction of the inflatable component 110. During inflation, the outer melamine sound insulation pad tightly adheres to the fixed surface 300, the middle foam layer enhances sound absorption after compression, and the inner aluminum foil membrane maintains its shape stability, preventing wrinkles from affecting reflection efficiency. During deflation and contraction, each layer of material can return to its original shape with the inflatable component 110 without permanent deformation, ensuring that the initial acoustic performance is maintained even after multiple cycles of use. This solves the problem of sealing failure caused by deformation in traditional rigid sound insulation materials.

[0043] The outer melamine sound insulation pad can be customized in color according to the decorative style of the movable wall 200, such as white, gray, or wood color, to coordinate with the texture of the wall surface and avoid the problem of traditional exposed sound insulation strips damaging the aesthetics; the overall structural thickness is controllable and can be embedded in the installation groove 210 of the movable wall 200 without exceeding the wall surface, so as not to affect the normal movement of the movable wall 200, such as translation and rotation, thus taking into account both functionality and spatial coordination.

[0044] See Figures 1 to 3 As shown, in one embodiment, the prefabricated indoor space movable wall 200 with a silent caulking structure includes an air pump 130 and an inflation pipe 140 connected between the air pump 130 and the inflation component 110.

[0045] The air pump 130, acting as a power source, can drive the inflation component 110 to expand by outputting a stable air pressure, such as 0.15MPa to 0.18MPa. This ensures that the inflation component 110 can fully fill the gap between the movable wall 200 and the fixed surface 300 during operation, forming a tight seal with the sound insulation component 120 and blocking the airborne sound transmission path. Simultaneously, the controllability of the air pump 130 can adapt to the filling requirements of different gap sizes, avoiding poor sealing due to insufficient inflation or damage to the inflation component 110 due to over-inflation, thus improving the adaptability of the filling structure. The inflation pipe 140, serving as the gas transmission channel between the air pump 130 and the inflation component 110, can have its diameter and length optimized according to the wall structure to ensure smooth gas flow.

[0046] When the movable wall 200 needs to be fixed in place, the air pump 130 can quickly supply air to the inflatable component 110 through the inflation hose 140, causing the inflatable component 110 to expand within 3 to 5 seconds and come into contact with the fixed surface 300. The inflation hose 140 is made of a high-pressure resistant and aging-resistant material, such as polyurethane, which can withstand the air pressure output by the air pump 130 for a long time, reducing the risk of gas leakage. The air pump 130 and the inflation hose 140 can be connected by a quick connector for easy disassembly. When the inflation hose 140 or the air pump 130 malfunctions, the component can be replaced individually without having to completely dismantle the caulking structure or the wall, reducing maintenance difficulty and cost. In some embodiments, the inflatable component 110 can be an airbag.

[0047] See Figures 1 to 3 As shown, in one embodiment, the prefabricated indoor movable wall 200 uses a silent caulking structure including an exhaust pipe 150, with an exhaust valve 151 connected to the exhaust pipe 150. When the movable wall 200 needs to be moved again, the air pump 130 stops supplying air, and the gas inside the inflatable component 110 can be quickly discharged through the exhaust valve 151 and the exhaust pipe 150, realizing the rapid switching between the inflatable component 110's contracted and expanded states, meeting the dynamic needs of the movable wall 200 for flexible adjustment, and avoiding the impact of slow inflation and deflation on the user experience. In other embodiments, the exhaust valve 151 can also be directly installed on the inflation pipe 140 to quickly discharge the gas inside the inflatable component 110 through the exhaust valve 151.

[0048] In one embodiment, the silent joint filling structure for the prefabricated indoor space movable wall includes a controller and a monitoring unit, the controller being used to adjust the working state of the air pump according to the parameter values ​​detected by the monitoring unit.

[0049] This design eliminates the need for manual operation of the air pump; the controller automatically completes the inflation and deflation process based on parameter feedback from the monitoring unit. For example, once the wall is in place, the controller automatically starts the air pump to inflate it, as confirmed by a position sensor. When the wall needs to be moved, upon receiving a movement command, the controller first instructs the exhaust valve to release air. Once the monitoring unit confirms that the air pressure has dropped to a safe level, the wall can be moved. The entire process requires no manual intervention, significantly improving ease of operation, and is particularly suitable for scenarios involving frequent adjustments to spatial layout.

[0050] In one embodiment, the monitoring unit includes a pressure detection module for collecting the air pressure value of the inflatable component; the controller has a preset air pressure standard threshold. When the air pressure value collected by the pressure detection module reaches the air pressure standard threshold, the controller controls the air pump to stop working; when the air pressure value is lower than the air pressure standard threshold, the controller controls the air pump to inflate and pressurize the inflatable component.

[0051] The pressure detection module collects the air pressure value inside the inflatable component in real time. The controller forms a closed-loop control based on preset air pressure standard thresholds (e.g., 0.15MPa to 0.18MPa, adapted according to the gap size). When the air pressure in the inflatable component is insufficient (below the air pressure standard threshold) due to initial inflation or long-term use, the controller immediately starts the air pump to replenish air, ensuring that the inflatable component always maintains a tightly expanded state in contact with the fixed surface, preventing sound leakage due to air pressure attenuation. When the air pressure reaches the threshold, the controller promptly shuts off the air pump to prevent over-inflation that could lead to component rupture, wall deformation, or energy waste. This dynamic pressure replenishment mechanism solves the problems of insufficient sealing or over-inflation associated with traditional manual inflation, ensuring long-term stable sound insulation performance.

[0052] Furthermore, the system automates the inflation process entirely through pressure detection and automatic control, eliminating the need for manual monitoring or adjustment by the user: once the moving wall is in place, the controller receives a signal and starts the air pump, automatically stopping once the pressure detection module reports that the air pressure has reached the target. In daily use, if the air pressure drops due to minor leaks in the inflation components (such as aging of the interface seals), the system can replenish the pressure without the user noticing.

[0053] The setting of the air pressure standard threshold takes into account both sealing requirements and equipment tolerance (such as the long-term pressure resistance limit of rubber air bladders), avoiding accelerated aging of inflatable components due to continuous high pressure; at the same time, the pressure detection module can detect abnormal air leakage in a timely manner (such as a sudden drop in air pressure ≥10% / minute), and the controller can provide feedback on the fault through early warning prompts (such as information pushed by the smart home system), which makes it convenient for users to perform maintenance in advance (such as replacing seals) and prevent small faults from escalating into equipment damage.

[0054] In some embodiments, the pressure detection module may be a pressure sensor.

[0055] In one embodiment, the controller also presets a pressure safety threshold; the ratio of the pressure safety threshold to the pressure standard threshold is 1.5 to 2 times; when the pressure sensor detects that the pressure of the inflation component exceeds the pressure safety threshold, the controller controls the air pump to stop inflation.

[0056] The standard air pressure threshold primarily ensures the basic requirement for sealing gaps, while the air pressure safety threshold serves as a second line of defense, handling extreme situations (such as momentary failure of the pressure detection module, delay in air pump control commands, or abnormal pressure spikes caused by partial blockage of the inflation component). When the air pressure in the inflation component exceeds the safety threshold, the controller forcibly shuts down the air pump to prevent the inflation component from rupturing due to prolonged exposure to pressures far exceeding its design withstand value, or from being squeezed and deformed by excessive expansion into the mounting groove of the movable wall. This significantly reduces the risk of equipment damage and extends the service life of core components such as the inflation component and air pump.

[0057] The mounting slots and surrounding structures of prefabricated movable walls have their load-bearing and deformation limits. If the air pressure of the inflatable components increases without upper limit, it may lead to local bulging of the wall, loosening of the fixing surface, or even displacement of the entire structure, affecting the safety of space use. Setting a safety threshold can be achieved by limiting the maximum air pressure (e.g., when the standard threshold is 0.15MPa, the safety threshold is set to 0.225MPa to 0.3MPa) to ensure that the expansion force of the inflatable components is always within the range that the wall structure can withstand, thus eliminating structural safety hazards caused by equipment failure.

[0058] In one embodiment, the monitoring unit includes an environmental noise monitoring module, which collects the noise decibel value of the adjacent space and transmits it to the controller. The controller has a preset noise threshold. When the noise decibel value collected by the environmental noise monitoring module exceeds the noise threshold, the controller controls the air pump to inflate and pressurize the inflation component so that the air pressure of the inflation component is increased to a preset enhancement value. When the noise decibel value is lower than or equal to the noise threshold, the controller controls the air pressure of the inflation component to be maintained at a standard value.

[0059] Thus, the system automatically switches air pressure based on noise monitoring, eliminating the need for manual adjustment by the user. For example, with a noise threshold of 35 decibels, if a sound exceeding 35 decibels (such as footsteps in a hallway) occurs in an adjacent space of the bedroom at night, the controller will initiate air replenishment within 3 seconds, maintaining a quiet environment without the user noticing. During the day, when noise levels are low, the system automatically reduces air pressure, decreasing the frequency of the air pump's operation. This dynamic adjustment triggered by noise reduces the ineffective operating time of the air pump (e.g., during the day when noise levels are low, the air pump's start-up frequency is reduced by more than 60%), lowering energy consumption. Simultaneously, it avoids the inflation components being under high pressure for extended periods, reducing fatigue wear, extending service life, and lowering maintenance costs.

[0060] In some embodiments, the environmental noise monitoring module can be a high-precision noise sensor.

[0061] In some embodiments, a timer can also be set to automatically adjust the air pressure back to the standard value or slightly higher than the standard value, such as 1.1 times the standard value, if the noise continues to exceed the noise threshold for more than 8 hours, so as to balance the sound insulation effect and the fatigue wear of the airbag.

[0062] In one embodiment, the inflatable component includes a rubber liner, a metal mesh frame, and a damping coating arranged sequentially. The metal mesh frame is embedded in the outer side of the rubber liner, and the damping coating covers the outer side of the metal mesh frame. In the moving state, the inflatable component contracts, and the metal mesh frame and the rubber liner together maintain a compact shape to avoid interference with surrounding structures. In the fixed state, the rubber liner expands to provide sealing force, the metal mesh frame ensures that the expansion direction is accurately directed towards the gap, and the damping coating enhances the fit and sound insulation.

[0063] Specifically, the rubber inner liner, as the core sealing layer of the inflatable component, possesses excellent elastic deformation capabilities: during inflation, it expands towards the gaps as the air pressure increases, tightly fitting the fixing surface and filling irregular gaps caused by installation errors or slight deformation of the wall; after deflation, it quickly retracts into the mounting groove, without affecting the translation or rotation of the moving wall. Its high sealing performance blocks the direct path of airborne sound transmission, and simultaneously, as a gas-bearing carrier, it provides basic structural support for the entire inflatable component, solving the problem that traditional rigid sealant materials cannot adapt to dynamic gaps.

[0064] In some embodiments, the rubber liner may be made of EPDM rubber, which has excellent aging resistance, weather resistance and elasticity, ensuring the sealing and expansion and contraction performance of the inflatable component under different temperature conditions.

[0065] In some embodiments, the thickness of the rubber liner is set to 2mm to 3mm, which ensures good elasticity and sealing while providing sufficient expansion force during inflation.

[0066] The metal mesh skeleton embedded on the outside of the rubber liner effectively resists the radial expansion force during inflation, limiting excessive deformation of the rubber liner and preventing bulging, cracking, or shape distortion caused by long-term high pressure. Simultaneously, the supporting effect of the metal mesh ensures that the inflatable component maintains its initial shape after repeated inflation and deflation cycles, significantly extending its service life. This solves the defects of single rubber airbags, such as easy aging and weak resistance to deformation, ensuring long-term stable sealing performance.

[0067] In some embodiments, the metal mesh frame can be made of aluminum alloy micromesh with a mesh size of 5mm×5mm and a wire diameter of 0.3mm. It is lightweight and high-strength, and will not significantly increase the overall weight of the inflatable component, while effectively improving structural stability.

[0068] The damping coating covering the outside of the metal mesh frame has high damping characteristics. On the one hand, when it comes into contact with the fixed surface, its adhesive properties fill the tiny unevenness of the contact surface, enhancing the tightness of the fit and further reducing sound leakage from gaps. On the other hand, it can absorb the frictional vibration energy when the inflatable components come into contact with the wall, reducing abnormal noises caused by collisions during the adjustment of the moving wall (such as the friction noise between the metal frame and the wall). At the same time, the damping coating itself can dissipate sound wave energy, forming a double sound barrier with the rubber inner liner, improving the blocking effect on mid- and low-frequency noise and compensating for the limited sound insulation frequency range of a single rubber material.

[0069] In some embodiments, the damping coating is made of butyl rubber, which has good damping performance, adhesion, and aging resistance, and can adhere tightly to the outside of the metal mesh frame. The coating thickness can be from 1 mm to 1.5 mm, and can be adjusted according to actual sound insulation requirements.

[0070] In one embodiment, the wall of the mounting groove and the inflatable component are respectively provided with a first magnetic chuck and a second magnetic chuck; the first magnetic chuck and the second magnetic chuck cooperate to fix the inflatable component to the mounting groove.

[0071] Magnetic adsorption enables rapid positioning and initial fixation. During installation, simply align the second magnetic attachment of the inflatable component with the first magnetic attachment on the wall of the mounting groove; the components will automatically adhere and be fixed by magnetic force. Subsequent installation can be completed simply by pressing to confirm the position. The magnetic adsorption provides a continuous and uniform adsorption force, effectively limiting the relative displacement between the inflatable component and the mounting groove during inflation and deflation (especially the outward thrust generated during inflation), preventing positional shifts or detachment due to force. Simultaneously, magnetic adsorption does not affect the elastic deformation of the inflatable component, ensuring that it can smoothly extend into the gap during expansion and accurately return to the mounting groove during contraction, without interfering with the normal movement of the movable wall, thus balancing fixation reliability and dynamic adaptability.

[0072] In addition, the magnetic fixation is a detachable connection. When the inflatable part needs to be replaced due to aging or damage, there is no need to remove the wall or damage the installation groove structure. The old inflatable part can be removed by overcoming the magnetic force, and the new part can be replaced and then reset by magnetic attraction, which significantly reduces maintenance costs.

[0073] In some embodiments, neodymium iron boron strong magnet strips can be embedded in the wall of the mounting groove. The neodymium iron boron strong magnet strips are 3mm thick and 15mm wide. A galvanized steel plate with a thickness of 1mm is fixed on the corresponding inflatable component. The magnetic force is used to achieve preliminary positioning and pre-fixation to ensure that the airbag position is accurate during installation.

[0074] In other embodiments, the inflatable element may also be attached to the mounting groove of the movable wall.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
