Description

Technical Field

[0001] The utility model relates to the technical field of building doors and windows, in particular to a sound-insulating and noise-reducing door and window. Background Art

[0002] Early soundproof door and window designs mainly relied on increasing the thickness of the glass to achieve basic soundproofing, but this could not effectively block the penetration of low-frequency noise. To further improve the soundproofing performance, soundproof windows with multiple layers of different materials have gradually appeared on the market, such as laminated glass and hollow glass. These designs block the propagation of sound by adding specific soundproofing materials or air layers between the glass layers. However, even so, the isolation effect for high-frequency and some mid-frequency noise is still limited.

[0003] In response to the above problems, the application of sound insulation and noise reduction technology in the field of doors and windows has developed rapidly in recent years, among which vacuum sound insulation technology has received widespread attention due to its excellent sound insulation performance. As a means of almost completely eliminating gas sound transmission, the vacuum layer can greatly reduce the efficiency of sound transmission, especially for medium and low frequency noise. Therefore, combining vacuum technology with multi-layer sound insulation glass to form high-performance sound insulation and noise reduction doors and windows has become an important direction for solving modern urban noise problems.

[0040] Figure 1 A schematic diagram of the structure of a soundproof and noise-reducing door and window provided by one embodiment of the utility model; Figure 2 for Figure 1 The above diagram is not an actual scale of the actual product.

[0041] like Figure 1 and Figure 2 As shown, a sound insulation and noise reduction door and window according to an embodiment of the utility model comprises: a window sash frame 1, a multi-layer sound insulation glass group and a vacuum pump connector 2.

[0042] Among them, the window sash frame 1 is one of the key components in the door and window structure. Especially in the design of soundproof and noise-reducing doors and windows, the role of the window sash frame 1 is particularly critical. It not only carries the glass components, but also participates in realizing the sealing, stability and sound insulation of the doors and windows. According to the above technical solution, the design features of the window sash frame 1 can be described in detail as follows:

[0043] Material selection: The window sash frame 1 is usually made of materials with high strength, corrosion resistance, and good thermal insulation performance, such as aluminum alloy, stainless steel, PVC plastic or composite wood, etc. These materials can ensure that the window sash frame 1 remains stable and not easily deformed during long-term use, and at the same time has certain sound insulation performance.

[0044] Structural design: The window sash frame 1 needs to be precisely designed to accommodate the inlay of the multi-layer soundproof glass set, and its inner cavity size needs to perfectly match the multi-layer soundproof glass set to ensure that the glass is firmly embedded without leaving any gaps. Special grooves or bayonet holes may be designed around the frame to facilitate the installation of the shock-absorbing soundproof pad 10 and the fixing of the glass set.

[0045] Sound insulation pad integration: The position where the inner wall of the window sash frame 1 contacts the multi-layer sound insulation glass group is equipped with a shock-absorbing sound insulation pad 10. These pads are generally made of rubber, silicone or other highly elastic materials, which can absorb and disperse the noise generated by external vibrations, further improving the sound insulation effect. In such an embodiment, the inner surface of the shock-absorbing sound insulation pad 10 may be designed with grooves for accurately positioning and fixing each tempered glass to ensure that the glass is tightly and evenly distributed.

[0046] Sealing: In order to achieve good sound insulation, the sealing between the window frame 1 and the glass is crucial. This is usually achieved by applying sealant or installing sealing strips on the contact surface between the window frame 1 and the glass to ensure that there is no air or sound leakage. In addition, as mentioned in the technical solution, the connection between the vacuum pump connector 2 and the window frame 1 also needs to be sealed to prevent the vacuum layer 7 from leaking.

[0047] Installation interface: The window sash frame 1 provides an installation interface for the vacuum pump connector 2, including a preset through hole, which facilitates the installation and removal of the vacuum pump connector 2, while also ensuring the air tightness of the system.

[0048] Strengthening stability: In order to enhance the stability and load-bearing capacity of the overall structure, the window sash frame 1 may also be designed with reinforcing ribs or a frame reinforcement structure, especially in large doors and windows or in situations where greater wind pressure needs to be withstood.

[0049] In summary, as the core component of soundproof and noise-reducing doors and windows, the design of the window sash frame 1 must not only consider the stability of the structure and the convenience of installation, but also carefully consider various aspects of performance such as sound insulation and sealing to ensure efficient sound insulation of doors and windows in complex environments.

[0050] In one embodiment, the multi-layer soundproof glass group includes a first tempered glass 3, a second tempered glass 4, a third tempered glass 5 and a fourth tempered glass 6 which are arranged in sequence and in parallel; a first sound insulation layer 8 is formed between the first tempered glass 3 and the second tempered glass 4; a second sound insulation layer 9 is formed between the third tempered glass 5 and the fourth tempered glass 6; a vacuum layer 7 is formed between the second tempered glass 4 and the third tempered glass 5; the first sound insulation layer 8 and the second sound insulation layer 9 are filled with dry gas; damping sound insulation films are affixed to the inner surfaces of the first tempered glass 3 and the fourth tempered glass 6; damping sound insulation films are affixed to both surfaces of the second tempered glass 4 and the third tempered glass 5.

[0051] The design of this multi-layer soundproof glass set is a highly optimized soundproof solution. Through a carefully laid out multi-layer structure, it effectively blocks noise of different frequencies and improves the soundproofing performance of doors and windows. The specific structure, function and beneficial effects are as follows:

[0052] Structural Description

[0053] Four-layer tempered glass arrangement: The glass group consists of four pieces of tempered glass, namely a first tempered glass 3, a second tempered glass 4, a third tempered glass 5 and a fourth tempered glass 6, which are parallel to each other and arranged in sequence to form a multi-level structural system.

[0054] Double sound insulation layer and vacuum layer 7: A first sound insulation layer 8 is formed between the first tempered glass 3 and the second tempered glass 4, and a second sound insulation layer 9 is formed between the third tempered glass 5 and the fourth tempered glass 6. A vacuum layer 7 is provided between the two sound insulation layers, i.e., between the second tempered glass 4 and the third tempered glass 5. Such a layout is intended to improve the sound insulation efficiency through the combined effect of different sound insulation mechanisms (solid sound insulation and vacuum sound insulation).

[0055] Dry gas filling: The first sound insulation layer 8 and the second sound insulation layer 9 are filled with dry gas, such as argon or krypton. The thermal conductivity of these gases is lower than that of air, which helps to further reduce heat transfer and sound transmission, while avoiding condensation inside and maintaining the durability of sound insulation performance.

[0056] Application of damping sound insulation film: Damping sound insulation film is affixed to the inner surface of the first tempered glass 3 and the fourth tempered glass 6, as well as the two surfaces of the second tempered glass 4 and the third tempered glass 5. This film material can effectively absorb and transform sound wave energy, reduce vibration propagation, and further enhance the sound insulation effect.

[0057] effect

[0058] Multiple sound insulation barriers: By setting up two solid sound insulation layers and a vacuum layer 7, a triple sound insulation barrier is formed. Each layer has a different degree of attenuation effect on sound waves of different frequencies. In particular, the vacuum layer 7 almost completely blocks the air sound transmission path, greatly improving the isolation ability of low-frequency noise.

[0059] Vibration suppression: The application of damping sound insulation film effectively absorbs the vibration caused by sound waves hitting the glass, reduces the transmission of sound between the glass, and further reduces noise penetration.

[0060] Environmental adaptability: The filling of dry gas not only enhances the thermal insulation performance, but also improves the durability of the entire system, especially in environments with large temperature differences, avoiding internal condensation and maintaining long-term sound insulation effects.

[0061] Beneficial Effects

[0062] Wide-band sound insulation: This structure can effectively isolate a wide range of frequency noise from low frequency to high frequency, and is particularly suitable for urban environments with complex noise, providing users with a quiet living and working space.

[0063] Energy saving and heat preservation: Dry gas filling and vacuum layer 7 design improve the heat preservation performance of doors and windows, reduce energy consumption, and meet the requirements of modern green buildings.

[0064] Safe and durable: All glass is tempered, so even if it breaks, it will not form sharp fragments, ensuring the safety of users. The multi-layer structure and the selection of high-quality materials also ensure the long-term stability and durability of doors and windows.

[0065] The multi-layer soundproof glass group is embedded in the window frame 1, and the connection position of the multi-layer soundproof glass group and the inner wall of the window frame 1 is provided with a shock-absorbing soundproof pad 10. This design detail highlights the precision of the structure and the attention to detail of the soundproof and noise-reducing doors and windows, and aims to enhance the sound insulation effect and improve the overall user experience through the following aspects:

[0066] Precision inlay: The multi-layer soundproof glass set is carefully designed and precisely inlaid in the window frame 1, which means that the glass and the window frame are closely matched through the shock-absorbing sound insulation pad 10. This precision is not only related to aesthetics, but also the key to the sound insulation effect, because any tiny gap may become a channel for sound leakage.

[0067] Shock absorption and buffering: Shock absorption and sound insulation pads 10 are arranged at the connection position between the multi-layer sound insulation glass group and the inner wall of the window frame 1. These pads are usually made of highly elastic and sound-absorbing materials, such as rubber or special foam. Their function is to absorb and disperse external vibration and sound wave impact, reduce the direct transmission of these energies to the glass, and further reduce the spread of noise.

[0068] Sealing and stability: In addition to the functions of sound insulation and shock absorption, the shock-absorbing sound insulation pad 10 can also provide an additional sealing effect to prevent air and moisture from penetrating into the interface between the glass and the window frame. This is crucial for maintaining the vacuum state of the sound insulation layer (especially the vacuum layer 7). It can also prevent structural loosening caused by expansion or contraction caused by climate change.

[0069] Protect glass: The vibration-absorbing and sound-insulating pad 10 can also serve as a protective layer to reduce the risk of damage to the glass caused by improper installation or external impact, and extend the service life of doors and windows.

[0070] Comprehensive Benefits

[0071] Comprehensively improve sound insulation performance: This design achieves all-round noise isolation through the comprehensive use of multi-layer sound insulation materials, vacuum layer 7, dry gas filling, damping sound insulation membrane and precise inlay and sealing technology, especially in dealing with low-frequency and mid-frequency noise in complex acoustic environments.

[0072] Enhanced user experience: Not only does it have a significant sound insulation effect, but it also reduces vibration and noise transmission, making the living or working environment more comfortable and peaceful, which plays a positive role in improving the quality of life and promoting health.

[0073] Structural stability and safety: The addition of the shock-absorbing and sound-insulating pad 10 not only strengthens the overall structural stability of the doors and windows, but also increases the safety of use by reducing the risk of glass breakage.

[0074] Specifically, grooves are arranged at intervals on the inner surface of the shock-absorbing and sound-insulating pad 10 for clamping the edges of the first tempered glass 3 , the second tempered glass 4 , the third tempered glass 5 and the fourth tempered glass 6 .

[0075] Each groove is specially designed to fit the edge of the tempered glass, ensuring that each piece of glass can be accurately inserted into the predetermined position. This not only improves the convenience and efficiency of installation, but more importantly ensures the correct alignment of the soundproof glass group, avoiding the degradation of soundproofing performance due to installation deviation.

[0076] The tight fit between the groove and the glass edge forms a physical locking mechanism that effectively prevents the glass from moving or misaligning even when encountering strong vibrations or external pressure, ensuring the long-lasting stability of the sound insulation structure.

[0077] The precise snap-fit ​​design helps to form a more complete seal and reduce the possibility of air leakage. This is critical for systems that rely on air layers (such as dry gas fill layers) and vacuum layers7 to achieve sound insulation, helping to maintain the long-term effectiveness of sound insulation performance.

[0078] The groove design also helps to disperse the stress on the glass edge, avoiding damage to the glass or premature aging of the sound insulation pad due to excessive local force. By evenly distributing external forces, the durability and reliability of the entire system are improved.

[0079] The shock-absorbing and sound-insulating pad 10 with positioning grooves simplifies the on-site installation steps. Workers only need to put the glass accurately according to the guidance of the grooves without the need for additional complex adjustments, which reduces the possibility of installation errors and speeds up the construction progress.

[0080] The special groove design of this shock-absorbing sound insulation pad 10 not only ensures the structural stability and sound insulation performance of the soundproof window at the technical level, but also improves the accuracy and convenience of installation in actual operation. It is an ingenious and practical innovation in the design of soundproof and noise-reducing doors and windows.

[0081] In one embodiment, one end of the vacuum pump connector 2 is disposed in the vacuum layer 7, and the other end is disposed outside the window sash frame 1. Its functions and beneficial effects mainly include the following points:

[0082] effect

[0083] Establishing vacuum connection: The vacuum pump connector 2 serves as a bridge between the vacuum layer 7 and the external vacuum pump, with one end of the connector penetrating deep into the vacuum layer 7, ensuring that air can be effectively extracted to create and maintain the vacuum state of the vacuum layer 7. This is the key to achieving efficient sound insulation, because sound cannot be transmitted through the air in a vacuum, which greatly reduces the efficiency of sound transmission.

[0084] Easy maintenance and inspection: Located at one end outside the window frame 1, the vacuum layer 7 can be evacuated or inspected by connecting an external vacuum pump when necessary, which facilitates daily maintenance and regular vacuum inspection. If the vacuum layer 7 is found to be leaking for some reason, it can be repaired quickly to restore its sound insulation performance.

[0085] Controllable regulation: In some advanced designs, the vacuum pump connector 2 may be equipped with a one-way valve 11 or a regulating device that can control the direction and speed of gas flow, which is very useful for accurately managing the vacuum state of the vacuum layer 7, ensuring the stability and efficiency of the system.

[0086] Beneficial Effects

[0087] Enhanced sound insulation performance: By maintaining the vacuum state of the vacuum layer 7, the sound insulation effect is significantly improved, especially the isolation of low-frequency noise, which is difficult to match with other sound insulation methods. This allows the doors and windows to maintain a quiet indoor environment even in a noisy environment.

[0088] Improved durability: Easy maintenance means that potential problems can be discovered and resolved promptly, avoiding the degradation of sound insulation due to failure of the vacuum layer 7, thereby extending the service life of the door and window and the durability of the sound insulation effect.

[0089] Flexibility and adaptability: The external vacuum pump connector 2 design makes the doors and windows more flexible in installation and subsequent maintenance. The vacuum degree can be adjusted according to actual conditions to adapt to changes in different environments and usage requirements, thereby improving the versatility of the product and user satisfaction.

[0090] In summary, this layout design of the vacuum pump connector 2 not only technically ensures the efficient sound insulation performance of doors and windows, but also takes into account the convenience of later maintenance and the long-term stability of the system. It is an important component for achieving high-quality sound insulation and noise reduction doors and windows.

[0091] Specifically, the surface of the vacuum pump connector 2 is provided with an inner clamping platform 13 and an outer clamping platform 14 extending in a direction away from the center line of the vacuum pump connector 2; the vacuum pump connector 2 is inserted into the through hole so that the inner clamping platform 13 and the outer clamping platform 14 sandwich the window sash frame 1. A sealant is provided between the vacuum pump connector 2 and the window sash frame 1. The edge of the inner clamping platform 13 abuts against the shock-absorbing and sound-insulating pad 10.

[0092] This structural design is aimed at the connection between the vacuum pump connector 2 and the window sash frame 1, aiming to ensure a stable connection and efficient sealing between the two. Its detailed description, function and beneficial effects are as follows:

[0093] Structural Description

[0094] Clamping platform design: The surface of the vacuum pump connector 2 intentionally extends the inner clamping platform 13 and the outer clamping platform 14 away from its center line, forming a "clamping" structure. When the vacuum pump connector 2 is inserted into the through hole pre-reserved on the window sash frame 1, these clamping platforms are respectively located on the inner and outer sides of the window sash frame 1, close to the edge of the window frame.

[0095] Application of sealant: On the contact surface between the vacuum pump joint 2 and the sash frame 1, sealant is deliberately applied or installed to fill any tiny gaps to prevent air or moisture penetration and ensure the airtightness of the connection.

[0096] The inner snap-in platform 13 abuts against the sound insulation pad: the edge design of the inner snap-in platform 13 is in direct contact with the shock-absorbing sound insulation pad 10 installed on the inner wall of the window sash frame 1, which further enhances the sealing effect, helps to disperse the vibration that may be transmitted to the window frame, improves the sound insulation performance, and avoids the movement of the shock-absorbing sound insulation pad 10.

[0097] effect

[0098] Enhanced connection stability: The design of the inner clamping platform 13 and the outer clamping platform 14 not only provides a physically secure clamping to prevent the vacuum pump connector 2 from shifting under long-term use or external pressure, but also improves the stability of the entire door and window structure.

[0099] Ensure sealing: The use of sealant is a key link. It effectively prevents air from entering the vacuum layer 7 through the gap between the joint and the window frame, and maintains the vacuum state of the vacuum layer 7, which is crucial to maintaining efficient sound insulation performance.

[0100] Improved sound insulation effect: The direct contact between the inner card platform 13 and the shock-absorbing sound insulation pad 10 not only strengthens the sealing, but also further blocks the vibration transmitted through the structure, reduces the conduction of noise, and improves the overall sound insulation and noise reduction effect.

[0101] Beneficial Effects

[0102] Improve the durability of soundproof doors and windows: This design extends the service life of doors and windows by enhancing the stability and sealing of the connection parts, and reduces the frequency of repairs caused by poor sealing.

[0103] Optimized sound insulation performance: Through meticulous sealing measures and vibration control, the sound insulation effect is maximized, providing users with a quieter indoor environment.

[0104] Simplified installation and maintenance: The clear snap-on design and easy-to-apply sealant make the installation process simpler and faster, and it is also easier to check and deal with possible leaks during maintenance, improving user experience and satisfaction.

[0105] In summary, this structural design comprehensively considers the stability, sealing and sound insulation effects of the connection, and achieves efficient and lasting sound insulation and noise reduction effects through ingenious mechanical design and material application.

[0106] In a preferred embodiment, a plurality of one-way valves 11 are arranged in the air passage in the middle of the vacuum pump connector 2. The design of a plurality of one-way valves in the air passage in the middle of the vacuum pump connector has the core function of ensuring the stable operation of the vacuum system and effectively isolating the influence of the external environment on the vacuum state. The specific benefits include:

[0107] Prevent air backflow: The one-way valve 11 allows gas to flow in only one direction. When the vacuum pump stops working, these one-way valves 11 can prevent external air from flowing back into the vacuum layer, maintain the vacuum degree, and ensure that the sound insulation effect is not weakened due to changes in external air pressure.

[0108] Protecting the vacuum pump: When the vacuum pump is working, the one-way valve 11 can prevent the backflow phenomenon caused by the sudden change of pressure when the vacuum pump stops, thereby protecting the vacuum pump from damage and extending its service life.

[0109] Improve vacuuming efficiency: During the vacuuming process, the one-way valve 11 can prevent the extracted gas from flowing back to the vacuum pump inlet, thereby improving the vacuuming efficiency and ensuring that the required vacuum degree is quickly reached.

[0110] Maintaining system stability: The setting of the multi-stage one-way valve 11 can be regarded as a safety mechanism in the system. Even if a single valve fails, the other valves can still maintain the basic functions of the system, thereby increasing the reliability and stability of the system.

[0111] The design of arranging a plurality of one-way valves 11 in the vacuum pump connector 2 is an important enhancement to the overall performance of the vacuum system, ensuring efficient and stable sound insulation and noise reduction effects, while maintaining the long-term reliable operation of the system.

[0112] In a preferred embodiment, a plurality of vertebrae 15 are arranged at intervals on the outer side of the other end of the vacuum pump connector 2. The large end of the vertebrae 15 is close to the window sash frame 1.

[0113] This design feature involves the detailed structure of the vacuum pump connector 2, specifically the multiple vertebral portions 15 spaced apart on the outside thereof. The main functions and benefits of these vertebral structures can be summarized as follows:

[0114] Structural features

[0115] Cone 15 design: Multiple cone-shaped protrusions are arranged on the outer side of the vacuum pump connector 2 (the end away from the window sash frame 1), and these cones 15 are spaced apart along the axial direction of the connector. Each cone 15 has a certain length, one end of which is wider (large head end) close to the window sash frame 1, and the other end is relatively narrow.

[0116] Effects and Benefits

[0117] Enhanced structural strength: The setting of the conical portion 15 enhances the local strength of the vacuum pump joint 2, especially the design of the large end close to the window frame 1, which can effectively disperse external forces, prevent damage or deformation of the joint caused by external forces, and improve the structural stability of the entire door and window system.

[0118] Auxiliary sealing and fixing: The cone 15 may interact with the sash frame 1 or a special seal during installation to form a tighter fit. The design of the large end close to the sash frame 1 may help to form a better sealing effect at the connection, prevent air leakage, and further ensure the sealing and sound insulation performance of the vacuum layer 7.

[0119] In summary, the design of the conical portion 15 on the outside of the vacuum pump connector 2 not only functionally enhances the stability, sealing and installation convenience of the connector, but also takes the appearance design of the product into consideration to a certain extent. It is an example of optimizing the details of doors and windows for efficient sound insulation and noise reduction.

[0120] In another embodiment, it also includes a protective cap 12; the interior of the protective cap 12 is provided with an internal thread; the vacuum pump connector 2 is provided at one end outside the window sash frame 1 and is provided with an external thread that matches the internal thread; the protective cap 12 is covered on the end of the vacuum pump connector 2 that is provided outside the window sash frame 1, and is connected through the adaptation of the internal thread and the external thread.

[0121] This design adds a protective cap 12 structure, the purpose of which is to better protect the vacuum pump connector 2 and improve sealing and convenience. The specific functions and advantages are as follows:

[0122] Structural Description

[0123] Design of the protective cap 12: The protective cap 12 is an independent accessory designed to cover the exposed portion of the vacuum pump connector 2, and is provided with internal threads inside.

[0124] Threaded connection: The vacuum pump connector 2 is equipped with an external thread matching the internal thread of the protective cap 12 at the outer end of the window sash frame 1. By tightening the thread, the protective cap 12 is tightly connected to the vacuum pump connector 2.

[0125] Effects and Benefits

[0126] Protecting the vacuum pump connector 2: The use of the protective cap 12 can effectively prevent the vacuum pump connector 2 from being corroded by external factors such as dust, rain, and foreign matter, thereby protecting the connector from physical damage and corrosion and extending its service life.

[0127] Enhanced sealing: The threaded connection not only provides a stable physical fixation, but also further enhances the sealing between the vacuum pump connector 2 and the external environment, preventing air infiltration and ensuring that the vacuum state of the vacuum layer 7 is maintained, thereby not damaging the sound insulation effect.

[0128] Convenient maintenance and inspection: The protective cap 12 is designed to be easy to disassemble. When the vacuum pump connector 2 needs to be used, the user can easily unscrew the protective cap 12 and tighten it again after the operation is completed, which is convenient and quick.
