Description

Technical Field

[0001] This invention relates to a soundproof glass, specifically a soundproof glass with a double-layer hollow structure. Background Technology

[0002] Soundproof glass is commonly used in environments requiring acoustic isolation, such as residences, offices, recording studios, schools, hospitals, and automobiles, to reduce external noise interference. Traditional soundproof glass often employs a double or multi-layered glass structure, which may be filled with air or other inert gases, such as argon or Cripton gas. These structures can effectively reduce the transmission of sound waves through the glass to a certain extent.

[0003] However, although traditional soundproof glass shows some effectiveness in reducing noise, it has a significant limitation: the soundproofing effect is fixed.

[0004] Once soundproof glass is installed, its sound insulation performance is fixed and cannot be adjusted according to different environmental needs. This fixedness brings several drawbacks:

[0005] 1. Different environments and application scenarios often require different levels of sound insulation. For example, a residence may need a higher level of sound insulation at night to ensure the sleep quality of its residents, while during the day it may not need the same high level of sound insulation. Traditional soundproof glass cannot adapt to this change in needs and cannot select the required sound insulation environment.

[0006] Second, in some cases, such as during a specific season or period of time, the level of external noise may decrease. At this time, high sound insulation performance is no longer necessary. Traditional soundproof glass cannot adjust its performance to adapt to this change, which may lead to excessive sound insulation and affect the acoustic transparency between indoors and outdoors.

[0007] Third, in emergency situations, such as fire or other situations requiring a rapid response, residents may need to hear external alarms or cries for help. High sound insulation performance may block the transmission of such sounds, increasing safety risks.

[0008] Therefore, developing a double-glazed, hollow soundproof glass with adjustable sound insulation performance to better adapt to different environments and user needs has become a necessary direction for technological improvement and the goal pursued by this invention. Summary of the Invention

[0009] To address the aforementioned problems, this invention provides a double-layered hollow soundproof glass. By employing a floating glass structure and a flexible, transparent soundproof panel that is linked to the floating glass, the shortcomings of existing technologies can be effectively overcome.

[0010] The present invention is achieved through the following technical solution: a double-layer hollow soundproof glass, including an outer frame, wherein a glass mounting cavity is formed in the middle of the outer frame, and the upper and lower surfaces of the outer frame are guide rail surfaces;

[0011] The glass is configured as at least two pieces, which are movably sealed within the glass mounting cavity and form a floating soundproof cavity between the two pieces of glass, which is filled with inert gas.

[0012] An elastic transparent sound insulation panel is installed inside the glass mounting cavity. Each glass panel corresponds to one elastic transparent sound insulation panel, and the upper and lower ends of each elastic transparent sound insulation panel are fixed to the sliding sealing layer on the glass. The left and right ends of each elastic transparent sound insulation panel extend toward the outer frame and slide in contact with the inner wall of the outer frame. The elastic transparent sound insulation panel forms a certain point at the middle position of the left and right ends. The elastic transparent sound insulation panel is positioned with the center of the inner wall of the outer frame through the positioning points of the left and right ends.

[0013] An elastic gas storage component is arranged in a pre-set hollow cavity within the outer frame. The inlet and outlet ends of the elastic gas storage component are connected to the sound insulation cavity. When the elastic gas storage component is squeezed, the inert gas inside the elastic gas storage component enters the floating sound insulation cavity, thereby pushing the two glass panels to move away from each other. At this time, the upper and lower ends of the elastic transparent sound insulation panel follow the movement of the glass, making the entire elastic transparent sound insulation panel arc-shaped, with its arc-shaped concave surface facing the glass side. Using the center position of the left and right ends of the elastic transparent sound insulation panel as the center positioning point, an arc-shaped sound insulation surface is formed on the formed arc-shaped concave surface.

[0014] As a preferred technical solution, the sliding sealing layer is wrapped and installed on the outside of the glass and serves as a sliding seal during the sliding process of the glass. The outer wall surface of the sliding sealing layer is in sealing contact with the inner wall surface of the glass mounting cavity. A bent connection part is formed at both the upper and lower ends of the elastic transparent sound insulation plate. The elastic transparent sound insulation plate is fixedly connected to the sliding sealing layer through the bent connection part.

[0015] As a preferred technical solution, a limiting ring is formed on the outer end of each glass piece of the outer frame, and an elastic sealing ring is provided on the inner end of each glass piece of the limiting ring corresponding to the sliding sealing layer. One side of the elastic sealing ring is fixedly bonded to the inner side of the limiting ring, and the other side is fixedly bonded to the sliding sealing layer of the glass. The elastic sealing ring is fixedly bonded to the contact surface of the outer frame.

[0016] As a preferred technical solution, the elastic sealing ring is made of a hollow elastic rubber material.

[0017] As a preferred technical solution, the positioning point at the center of the left and right ends of the elastic transparent sound insulation board adopts two positioning shafts, and positioning holes are provided on the outer frame corresponding to the positioning shafts, and the positioning shafts are positioned and installed in the positioning holes.

[0018] As a preferred technical solution, the elastic air storage component is made of elastic rubber material, and the elastic air storage component has a sealed air storage cavity. Each elastic air storage component is provided with at least one inlet and outlet air conduit. One end of the inlet and outlet air conduit communicates with the air storage cavity of the elastic air storage component, and the other end of the inlet and outlet air conduit extends into the sound insulation cavity.

[0019] As a preferred technical solution, a floating pressure plate is provided at the outer end of the elastic gas storage component, and a contact protrusion is formed at the inner end of the floating pressure plate and contacts the elastic gas storage component through the contact protrusion. The floating pressure plate has a locking positioning component, which is installed on the outer frame. The floating pressure plate is positioned after being pressed down by the locking positioning component, so that the inert gas in the elastic gas storage component is kept in the sound insulation cavity.

[0020] As a preferred technical solution, the locking and positioning component includes a locking nut, a locking screw hole is provided on the outer frame, and an external thread is provided on the outer circular surface of the locking nut, which engages with the thread of the locking screw hole;

[0021] It also includes a positioning rod, one end of which is fixedly connected to the inner side of the locking nut. A positioning through hole is opened on the outer frame opposite the positioning rod, and the positioning rod extends into the positioning through hole. The floating pressure plate has a fixing hole at the same height on the side corresponding to the positioning rod. When the floating pressure plate presses down on the elastic gas storage component to the limit position, the positioning rod is positioned directly opposite the fixing hole. At this time, the locking nut is manually rotated, so that the positioning rod is inserted into the fixing hole of the floating pressure plate.

[0022] As a preferred technical solution, the outer opening of the fixing hole is flared, the head of the positioning rod is rounded, and the outer end of the locking nut is provided with a protruding torsion part.

[0023] As a preferred technical solution, the elastic transparent sound insulation panel is made of thermoplastic polyurethane material, and a rubber sealing layer is provided at the left and right ends of the elastic transparent sound insulation panel, which is in sealed contact with the outer frame through the rubber sealing layer.

[0024] The beneficial effects of the present invention are as follows: First, the present invention achieves dynamic adjustment of sound insulation performance by combining an elastic gas storage component and an elastic transparent sound insulation board in a double-layer hollow soundproof glass system. By simply operating the elastic gas storage component, the gas volume in the sound insulation cavity can be changed, thereby adjusting the distance between the two glass panes, so that the sound insulation performance can be adapted according to changes in external environmental noise or the specific needs of the user.

[0025] Second, this invention uses an elastic transparent sound insulation board, which allows the board to form an arc-shaped structure with the concave side facing outward when adjusting the sound insulation performance. This concave structure can effectively scatter sound waves passing through the glass, reduce the straight-line transmission of sound waves, and thus reduce sound transmission. Compared with flat glass, it can more effectively scatter and absorb sound waves, providing a higher level of sound insulation effect.

[0026] Third, since the sound insulation performance of the soundproof glass of this invention can be adjusted as needed, the sound insulation level can be reduced when high sound insulation performance is not required, so as to allow more natural sound to enter, which helps to save energy waste caused by excessive sound insulation. At the same time, it is also more suitable for emergencies, such as fire, where it is necessary to hear external alarms and sounds to react quickly, providing more safety and comfort for the living and working environment.

[0039] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0040] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0041] like Figures 1-3 As shown, the present invention provides a double-layer hollow soundproof glass, including an outer frame 1, in which a glass 2 mounting cavity is formed in the middle. The upper and lower surfaces of the outer frame 1 are guide rail surfaces. The entire glass 2 can slide on the guide rails through the upper and lower guide rail surfaces, which is normal left and right displacement of the glass 2 to realize opening and closing.

[0042] It also includes glass 2, which in this embodiment is set to two pieces. The two pieces of glass 2 are movably sealed in the glass 2 mounting cavity and form a floating sound insulation cavity 12 between the two pieces of glass 2. The sound insulation cavity 12 is filled with an inert gas, such as argon, which has a lower thermal conductivity than air, which helps to improve heat insulation and sound insulation performance.

[0043] To further improve the sound insulation effect of the soundproof glass 2 without affecting light transmittance, an elastic transparent sound insulation plate 6 is also provided in this embodiment. The elastic transparent sound insulation plate 6 is set in the installation cavity of the glass 2, with one elastic transparent sound insulation plate 6 corresponding to each glass 2. The upper and lower ends of each elastic transparent sound insulation plate 6 are fixed to the sliding sealing layer 10 on the glass 2. The left and right ends of each elastic transparent sound insulation plate 6 extend towards the outer frame 1 and slide in contact with the inner wall of the outer frame 1. The elastic transparent sound insulation plate 6 forms a certain position at the middle position of the left and right ends. The elastic transparent sound insulation plate 6 is positioned by the positioning points of the left and right ends and the center of the inner wall of the outer frame 1. Therefore, the upper and lower ends and the center of the left and right sides of the elastic transparent sound insulation plate 6 are positioned. When the two glass 2 move away from each other, the upper and lower ends of the elastic transparent sound insulation plate 6 will continuously become arc-shaped around the positioning points, and the concave surface of the arc faces outward. When the two glass 2 move away from each other, the distance between the sound insulation cavities 12 increases, the amount of inert gas increases, and the sound insulation effect can be effectively improved.

[0044] In order to manually control the size of the sound insulation cavity 12, this embodiment also uses an elastic air storage component 15. The elastic air storage component 15 is arranged in a pre-set hollow cavity 5 inside the outer frame 1, and the air inlet and outlet ends of the elastic air storage component are connected to the sound insulation cavity 12.

[0045] When the elastic gas storage component 15 is squeezed, the inert gas inside the elastic gas storage component 15 enters the floating sound insulation cavity 12, thereby pushing the two glass panels 2 to move away from each other. At this time, the upper and lower ends of the elastic transparent sound insulation panel 6 follow the movement of the glass panels 2, making the entire elastic transparent sound insulation panel 6 arc-shaped, with its arc-shaped concave surface facing the glass panels 2. Using the center positions of the left and right ends of the elastic transparent sound insulation panel 6 as the center positioning points, an arc-shaped sound insulation surface is formed on the formed arc-shaped concave surface, such as... Figure 8 and Figure 9 As shown, when the two glass panes 2 move away from each other, the elastic transparent sound insulation panel 6 will become arc-shaped, while the position of the positioning point remains unchanged. Therefore, the farther away from the positioning point, the larger the distance between the two elastic transparent sound insulation panels 6; conversely, the closer to the positioning point, the smaller the distance between the two elastic transparent sound insulation panels 6. Figure 9In the process, gaps L1 and L2 are formed, with L1 being larger than L2. When the two glass panels 2 are reset, the elastic transparent sound insulation panel 6 will also be reset and become horizontal. At this time, the gap L1 is equal to the gap L2. When the elastic transparent sound insulation panel 6 is in an arc-shaped state, due to its arc-shaped concave surface, i.e., the arc-shaped sound insulation surface faces outward, the sound waves will be reflected and scattered in different directions when they encounter the concave surface. This helps to reduce the sound waves that are directly reflected into the room, thereby enhancing the sound insulation effect. It can change the propagation path of the sound waves, making it more difficult for them to directly pass through the glass 2 and enter the room, greatly improving the sound insulation effect. In the normal state, the elastic transparent sound insulation panel 6 is in a horizontal state and is used as a normal sound insulation panel.

[0046] like Figure 3 As shown, the sliding sealing layer 10 is installed around the outside of the glass 2 and serves as a sliding seal during the sliding process of the glass 2. The outer wall of the sliding sealing layer 10 is in sealing contact with the inner wall of the glass 2 mounting cavity. A bent connection part 7 is formed at both the upper and lower ends of the elastic transparent sound insulation plate 6. The elastic transparent sound insulation plate 6 is fixedly connected to the sliding sealing layer 10 through the bent connection part 7. The sliding sealing layer 10 can effectively increase the sound insulation between the glass 2 and the outer frame 1 support, prevent the inert gas filled in the sound insulation cavity 12 from escaping, and maintain airtightness.

[0047] A slot can be made at the position of the sliding sealing layer 10 corresponding to the bent connecting part 7. One end of the bent connecting part 7 is inserted into the slot and then glue is applied to improve the connection strength between the two.

[0048] Please continue reading. Figure 3 The outer frame 1 forms a limiting ring 11 at the outer end of each glass 2, and the inner end of the limiting ring 11 is provided with an elastic sealing ring 9 for each sliding sealing layer 10 of each glass 2. One side of the elastic sealing ring 9 is fixedly bonded to the inner side of the limiting ring 11, and the other side is fixedly bonded to the sliding sealing layer 10 of the glass 2. The contact surface of the elastic sealing ring 9 with the outer frame 1 is fixedly bonded. Due to the setting of the elastic sealing ring 9, the various surfaces of the elastic sealing ring 9 are bonded and sealed with the outer frame 1 and the sliding sealing layer 10. In this way, when the sliding sealing layer 10 moves, the position can be moved by squeezing the elastic sealing ring 9. After being squeezed, the elastic sealing ring 9 will be compressed and deformed to meet the displacement of the glass 2, while also meeting the sealing requirements to prevent the inert gas from escaping. The present invention adopts a double sealing method to effectively lock in the inert gas and increase the airtightness.

[0049] In this embodiment, in order to enable the elastic sealing ring 9 to have an elastic deformation effect, the elastic sealing ring 9 is made of hollow elastic rubber material, which can be designed as a hollow structure, making it easier to deform.

[0050] like Figures 5-7As shown, the positioning point of the elastic transparent sound insulation panel 6 at the center of the left and right ends is provided by two positioning shafts 13. The outer frame 1 corresponding to the positioning shafts 13 is provided with positioning holes. The positioning shafts 13 are positioned and installed in the positioning holes. The center of the left and right ends of the elastic transparent sound insulation panel 6 is positioned, so the displacement of the elastic transparent sound insulation panel 6 will only be arc-shaped, and will not be completely displaced in the horizontal direction, thereby realizing the arc shape of the elastic transparent sound insulation panel 6.

[0051] In this embodiment, in order to enable the elastic air storage component 15 to have elastic restoring capability, the elastic air storage component 15 is made of elastic rubber material. The elastic air storage component 15 has a sealed air storage cavity. At least one air inlet / outlet conduit 14 is provided on the elastic air storage component 15. One end of the air inlet / outlet conduit 14 communicates with the air storage cavity of the elastic air storage component 15, and the other end of the air inlet / outlet conduit 14 extends into the sound insulation cavity 12.

[0052] As a preferred technical solution, a floating pressure plate 3 is provided at the outer end of the elastic gas storage component 15. The inner end of the floating pressure plate 3 forms a contact protrusion and contacts the elastic gas storage component 15 through the contact protrusion. The floating pressure plate 3 has a locking positioning component, which is installed on the outer frame 1. The floating pressure plate 3 is positioned after being pressed down by the locking positioning component, so that the inert gas in the elastic gas storage component 15 is kept in the sound insulation cavity 12.

[0053] like Figure 4 and Figure 5 As shown, the locking and positioning component includes a locking nut 4, and a locking screw hole 17 is provided on the outer frame 1. The outer circular surface of the locking nut 4 is provided with an external thread, and the locking nut 4 is threadedly engaged with the locking screw hole 17.

[0054] It also includes a positioning rod 18, one end of which is fixedly connected to the inner side of the locking nut 4. A positioning through hole is opened on the outer frame 1 facing the positioning rod 18, and the positioning rod 18 extends into the positioning through hole. The floating pressure plate 3 is provided with a fixing hole 16 at the same height on one side corresponding to the positioning rod 18. When the floating pressure plate 3 presses down on the elastic gas storage component 15 to the limit position, the positioning rod 18 is positioned facing the fixing hole 16. At this time, the locking nut 4 is manually rotated to insert the positioning rod 18 into the fixing hole 16 of the floating pressure plate 3. When it is necessary to increase the sound insulation effect, the floating pressure plate 3 is manually pushed to the limit position, and then the locking nut 4 is rotated with the other hand to insert the positioning rod 18 into the fixing hole 16 to complete the positioning.

[0055] When a high level of sound insulation is not required, simply manually rotate the locking nut 4 in the opposite direction to separate the positioning rod 18 from the fixing hole 16, allowing the elastic gas storage component 15 to return to the inert gas that originally entered the sound insulation cavity 12, thus completing the repositioning of the two glass panes 2.

[0056] In order to allow the positioning rod 18 to be better inserted into the fixing hole 16, in this embodiment, the outer opening of the fixing hole 16 is flared, the head of the positioning rod 18 is rounded, and the outer end of the locking nut 4 is provided with a protruding torsion part.

[0057] The elastic transparent sound insulation panel 6 is made of thermoplastic polyurethane material. A rubber sealing layer is provided on the left and right ends of the elastic transparent sound insulation panel 6. The rubber sealing layer is in sealed contact with the outer frame 1. The rubber sealing layer increases the sealing between the elastic transparent sound insulation panel 6 and the outer frame 1. However, the sealing requirement here is not high. A certain level of sealing is sufficient. The purpose is to reduce the sound waves passing through the contact surfaces on both sides of the elastic transparent sound insulation panel 6 and improve the sound insulation effect of the elastic transparent sound insulation panel 6.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
