Description

Technical Field

[0001] The utility model relates to the technical field of vacuum glass, in particular to a multi-combination vacuum sound insulation glass. Background Art

[0002] The existing multi-layer vacuum soundproof glass technology, although it sets support members between the glass layers to form a cavity and attempts to improve the sound insulation effect by injecting inert gas or vacuuming, still has many shortcomings in practical applications.

[0003] First, the traditional support design is often relatively simple, and fails to fully consider the sound propagation characteristics and the sound insulation performance of the material. This may cause the support itself to become a "bridge" for sound propagation, greatly reducing the sound insulation effect. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-combination vacuum soundproof glass to solve the problem that the supporting parts of the existing vacuum glass may become a "bridge" for sound propagation, which greatly reduces the sound insulation effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-combination vacuum soundproof glass, comprising a first glass, a second glass and a third glass; a first support member is arranged between the first glass and the second glass, a first cavity that can be evacuated is provided between the first glass and the second glass, a broken bridge groove is opened on the first support member, a flexible film covering the outside of the broken bridge groove is arranged on the outer boundary of the first support member, and a fixing tape covering the inside of the broken bridge groove is arranged on the inner boundary of the first support member; the flexible film and the fixing tape enclose the broken bridge groove to form a soundproof cavity, and the soundproof cavity is filled with sound-absorbing spheres; the fixing tape is provided with a honeycomb through hole connected to the soundproof cavity.

[0006] Furthermore, the first support member includes support columns symmetrically arranged in pairs, and the support columns are located in the sound insulation cavity.

[0007] Furthermore, a shock-absorbing pad is fixedly connected to the support column.

[0008] Furthermore, an air extraction pipe is provided on the flexible film, and the air extraction pipe extends from the flexible film through the fixing tape into the first cavity.

[0009] Furthermore, the first cavity is a vacuum layer.

[0010] Furthermore, a second supporting member is provided between the second glass and the third glass, and a second cavity is formed between the second glass and the third glass.

[0011] Furthermore, a desiccant is placed in the second support member to make the second cavity a dry cavity layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Improve the sound insulation effect: By opening a broken bridge groove on the first support member, the sound propagation path can be effectively blocked, forming a broken bridge effect, thereby reducing the propagation efficiency of sound energy. At the same time, a flexible membrane and a fixing tape are combined with the first support member to form a closed sound insulation cavity. The sound-absorbing spheres filled in the sound insulation cavity can further absorb and consume sound energy, thereby significantly improving the sound insulation effect of the glass.

[0014] Enhanced structural stability: In the vacuum state, the flexible membrane can be tightly attached to the sound-absorbing sphere to ensure that it will not shake in the sound insulation cavity. This not only prevents the additional noise caused by the shaking of the sound-absorbing sphere, but also enhances the stability of the overall structure.

[0015] Application of innovative materials: The use of flexible membrane and fixing tape is an innovation, which replaces the traditional rigid material. It can not only delay the propagation of sound, but also better adapt to the changes in air pressure during vacuuming, ensuring the sealing of the sound insulation cavity.

[0016] Multiple sound insulation measures: In addition to the sound insulation design between the first glass and the second glass, a sound insulation damping film can be set between the second glass and the third glass. This multiple sound insulation measure can more effectively block the residual sound energy, thereby providing better sound insulation performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0027] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0028] like Figures 1 to 7As shown, the utility model provides a multi-combination vacuum soundproof glass, including a first glass 1, a second glass 2 and a third glass 3; the first glass 1, the second glass 2 and the third glass 3 are all made of light-transmitting glass with a thickness of 5MM, and a first support member 11 is arranged between the first glass 1 and the second glass 2. The first support member 11 is made of aluminum alloy, and the length and width of the first support member 11 are both 10MM smaller than the length and width of the selected glass. The thickness of the first support member 11 is 5MM, and the first support member 11 allows a first vacuumizable cavity 4 to be formed between the first glass 1 and the second glass 2. A broken bridge groove 12 is provided on the first support member 11, and the broken bridge groove 12 is hollowed out from the outer boundary to the inner boundary of the first support member 11, so that only four cylindrical support columns 1 at the right angle ends are left in the first support member 11. 11, the front panel and the bottom panel of the first support member 11 are connected by the support column 111, the flexible film 13 is fixed to the outer boundary of the first support member 11, and the fixing tape 14 is fixed to the inner boundary. The flexible film 13, the fixing tape 14 and the front panel and the bottom panel of the first support member 11 are enclosed, so that the broken bridge groove 12 forms a sound insulation cavity 5, the flexible film 13 is made of polyethylene (PE) material with strong flexibility and unbreakable properties, and the fixing tape 14 is made of carbon fiber material with undeformable and strong stability properties; the sound insulation cavity 5 is filled with sound-absorbing spheres 15; the fixing tape 14 is provided with a honeycomb through hole 16 connected to the sound insulation cavity 5, and the honeycomb structure itself has a high structural strength, so the design of the honeycomb through hole 16 can also enhance the structural stability of the fixing tape 14 to a certain extent. .

[0029] When the cavity is evacuated, the sound insulation cavity 5 will also be in a hollow state due to the honeycomb through holes 16. At this time, the flexible membrane 13 is in close contact with the sound absorbing sphere 15 due to the air pressure difference to fix it; the sound insulation groove opened on the first support member 11 can form a broken bridge effect to reduce the efficiency of sound energy transmission; a sound insulation damping membrane 6 is arranged between the second glass 2 and the third glass 3 to block the sound energy not absorbed by the sound insulation cavity 5. Among them, the flexible membrane 13 and the fixing tape 14 are used to replace part of the rigid structure of the first support member 11 to delay the propagation of sound, and the sound absorbing sphere 15 filled in the sound insulation cavity 5 is used to absorb sound energy and reduce sound transmission. At the same time, when evacuating, the flexible membrane 13 is in close contact with the sound absorbing sphere 15 to prevent it from shaking and making sounds, thereby improving the overall sound insulation effect.

[0030] Among them, the sound-absorbing sphere 15 is made of polyester fiber, and the surface and interior of the sphere formed by it contain a large number of open pores. This unique open-pore structure allows sound waves to enter the sound-absorbing sphere 15 and then be repeatedly refracted and scattered inside until the sound energy is finally converted into heat energy and absorbed, thereby achieving effective noise elimination.

[0031] The support column 111 on the first support member 11 is the support column 111 left by the broken bridge groove 12 for supporting the front panel and the bottom panel. The middle part of the support column 111 is partitioned, and a shock-absorbing pad 112 is added at the cut-off position. The shock-absorbing pad 112 includes an upper sleeve, a lower sleeve and a shock-absorbing plate. The upper sleeve is sleeved and fixed on the upper end of the partitioned support column 111, and the lower sleeve is sleeved and fixed on the lower end of the partitioned support column 111. Partitioning the support column 111 and adding the shock-absorbing pad 112 can not only effectively absorb the vibration of sound waves and reduce the propagation of noise, but also play a buffering role when the glass is impacted by external force, thereby protecting the soundproof glass from damage.

[0032] Among them, the support column 111 is located in the sound insulation cavity 5, and the sound-absorbing sphere 15 can also be wrapped around the outside of the support column 111 to further absorb the sound wave vibration absorbed by the shock-absorbing pad 112 and improve the diaphragm effect.

[0033] In order to facilitate the vacuuming operation of the first cavity 4, an exhaust pipe 131 is provided on the flexible film 13. The exhaust pipe 131 is a colloidal and hollow exhaust pipe 131. The exhaust pipe 131 extends from the flexible film 13 through the fixing tape 14 into the cavity and is connected to the exhaust device to extract the gas in the first cavity 4, thereby forming a vacuum environment. The vacuum environment can effectively insulate and soundproof and improve the sound insulation and heat insulation effect of the glass.

[0034] A second support member 22 is provided between the second glass 2 and the third glass 3. The second support member 22 is made of aluminum alloy. The second support member 22 forms a second cavity 23 between the second glass 2 and the third glass 3. The second cavity 23 has further sound insulation and heat insulation effects. A desiccant is placed on the second support member 22. The drying element on the second support member 22 can form a dry cavity layer in the second cavity 23. The dry cavity layer ensures that the glass will not frost when used in an environment with a large temperature difference between the inside and the outside.

[0035] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
