Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum glass, and specifically relates to a vacuum glass. Background Technology

[0002] Vacuum glass is a building material with excellent thermal and sound insulation properties. While traditional double-glazed windows offer some insulation, this relies primarily on the air gap. Vacuum glass, however, significantly improves insulation by creating a vacuum between the two panes of glass, greatly reducing heat conduction and convection. However, manufacturing vacuum glass presents several technical challenges. For instance, current vacuum glass structures lack a component to hold adhesive, making it prone to seeping into the glass surfaces when sealing the edges. Furthermore, using only welding or gluing techniques during the sealing process results in lower airtightness. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this application provides a vacuum glass to solve the above-mentioned technical defects.

[0004] According to a first aspect of this utility model, a vacuum glass is provided, comprising an upper glass layer and a lower glass layer. A groove is provided in the center of the surface of the lower glass layer. The area formed between the groove and the lower surface of the upper glass layer is a vacuum zone. Receiving grooves are symmetrically arranged on both sides of the groove, and the area within the receiving grooves is a sealing zone. The area between the contact surfaces of the upper and lower glass layers is a welding zone. This structural design prevents adhesive from penetrating to the glass bonding surface, and the vacuum glass exhibits good sealing properties and a long service life.

[0005] In a specific embodiment, the depth of the groove is greater than or equal to 0.2 mm and less than or equal to 1 / 3 of the thickness of the lower glass layer. This structural design ensures that the groove is deep enough to form an effective vacuum area, while maintaining the structural strength of the glass and preventing the lower glass layer from becoming brittle and prone to breakage.

[0006] In a specific embodiment, the length of the welding zone is greater than or equal to 2 mm, and the length of the sealing zone is greater than or equal to 1.6 mm. This structural design ensures that the molten glass fully penetrates, forming a continuous and dense weld, while also ensuring good sealing of the vacuum glass.

[0007] In a specific embodiment, a support column is pre-installed within the groove, connecting the bottom of the groove to the lower surface of the upper glass layer. This structural design ensures that the load generated by the vacuum negative pressure is evenly transferred to the lower glass layer, preventing localized stress concentration in the middle of the upper glass layer due to its suspended design.

[0008] In a specific embodiment, the support columns have a diameter of 0.3-0.8 mm, a spacing of 30-50 mm, and a height of 0.1-1 mm. An elastic buffer layer is provided between the support columns and the bottom of the groove and the upper glass, and the elastic buffer layer is applied to the bottom of the groove and the upper glass. This structural design ensures sufficient support while minimizing the contact area, reducing the thermal bridging effect, balancing structural strength and heat loss, reducing stress concentration, and the elastic buffer layer absorbs the impact of vibration or thermal expansion and contraction.

[0009] In a specific embodiment, a vacuum sensor is also provided in the groove. With this structure, the vacuum level in the vacuum zone can be accurately detected. Only when the detected vacuum level meets the standard required for a vacuum environment will the subsequent lamination operation be carried out.

[0010] In a specific embodiment, a mounting groove is provided at the bottom of the recess, and a vacuum sensor is installed inside the mounting groove. This structural design allows for accurate and stable measurement of the vacuum level within the recess, real-time monitoring of vacuum level changes, and timely detection of potential leaks or other problems, thereby providing early warning and extending the service life of the vacuum glass.

[0011] In a specific embodiment, the receiving groove is a pre-defined recess or notch, and adhesive is applied inside the recess or notch. This structural design provides a clearly defined filling area for the adhesive, preventing it from overflowing into non-target areas such as the vacuum zone and welding zone during the application process.

[0012] In a specific embodiment, the upper and lower glass layers are fixed together by adhesive bonding and welding, respectively. In this structural design, adhesive bonding serves as a flexible seal to buffer stress, while welding provides a rigid seal, completely preventing air leakage. This dual sealing method of adhesive bonding and welding enhances the airtightness of the vacuum glass and further extends its service life.

[0013] In a specific embodiment, bonding is performed in the sealing area, and welding is performed in the welding area. This structural arrangement, separating the sealing and welding processes, effectively avoids interference between them, thus improving the yield rate of vacuum glass products.

[0014] Compared with the prior art, the beneficial results of this utility model are as follows:

[0015] 1. Vacuum glass is equipped with a receiving groove to prevent glue from seeping into the glass bonding surface when sealing the edges of vacuum glass.

[0016] 2. Vacuum glass is sealed by both gluing and welding, resulting in excellent sealing performance and a long service life, and it is easy to process and produce. Attached Figure Description

Figure 1 As shown, a vacuum glass includes an upper glass layer 01 and a lower glass layer 02. A groove 03 is provided in the center of the surface of the lower glass layer 02. The area formed between the groove 03 and the lower surface of the upper glass layer 01 is a vacuum zone. Receiving grooves 04 are symmetrically arranged on both sides of the groove 03.

[0023] In a specific embodiment, the depth of the groove 03 is greater than or equal to 0.2 mm and less than or equal to 1 / 3 of the thickness of the lower glass 02.

In this example, the upper glass 01 has a thickness of 2 mm, the lower glass 02 has a thickness of 5 mm, and the depth of the groove 03 is 1 mm, which is 1 / 5 of the thickness of the lower glass 02.

[0024] In a specific embodiment, the length of the welding area 05 is greater than or equal to 2 mm, and the length of the sealing area is greater than or equal to 1.6 mm. This structural arrangement ensures sufficient penetration of the molten glass, forming a continuous and dense weld, while also ensuring good sealing of the vacuum glass. In this example, the welding area 05 and the sealing area are symmetrically arranged about the center of the groove 03. A welding area 05 and a sealing area are located on each side of the groove 03, with the sealing area on the outer side and the welding area 05 on the inner side. The welding area 05 has a length of 2 mm, and the sealing area has a width of 1.6 mm and a depth of 0.3 mm.

[0025] In a specific embodiment, a support column 06 is reserved in the groove 03, and the support column 06 connects the bottom of the groove 03 to the lower surface of the upper glass 01. Through this structural arrangement, the load generated by the vacuum negative pressure is evenly transferred to the lower glass 02, avoiding local stress concentration in the middle of the upper glass 01 caused by its suspended arrangement.

[0026] In a specific embodiment, the support columns 06 have a diameter of 0.3-0.8 mm, a spacing of 30-50 mm, and a height of 0.1-1 mm. Additionally, an elastic buffer layer 10 is provided at the bottom of the groove 03 and between the upper glass 01 and the support columns 06, respectively, and is attached to the upper glass 01 and the bottom of the groove 03. This structural design ensures sufficient support while minimizing the contact area, reducing thermal bridging, balancing structural strength and heat loss, reducing stress concentration, and absorbing the impact of vibration or thermal expansion and contraction. In this example, the support columns 06 are made of flexible carbon fiber, with a diameter of 0.6 mm, a height of 1 mm, and a matrix arrangement with a spacing of 30 mm × 30 mm. The elastic buffer layer is a 0.1 mm thick elastic transparent material layer.

[0027] In a specific embodiment, a vacuum sensor 07 is also provided within the groove 03. This structure allows for accurate detection of the vacuum level within the vacuum zone. Subsequent lamination operations are only performed when the detected vacuum level meets the required standard for a vacuum environment. In this example, a vacuum level ≤ 0.1 Pa meets the required environmental standard.

[0028] In a specific embodiment, the bottom of the groove 03 is provided with an assembly groove 08, the assembly groove 08 having dimensions of 1.0mm × 1.0mm × 0.5mm, and a vacuum sensor 07 is installed inside the assembly groove 08. This structural design allows for accurate and stable measurement of the vacuum level within the groove 03, real-time monitoring of changes in the vacuum level, and timely detection of potential leaks or other problems, thereby providing early warning and extending the service life of the vacuum glass.

[0029] In a specific embodiment, a getter 09 is also provided at the bottom of the groove 03. The getter 09 can continuously remove gas through chemical adsorption, maintain the vacuum level in the vacuum chamber, and thus extend the service life of the vacuum glass. In addition, the getter 09 can also be disposed within the hollow structure of the support column 06.

[0030] In a specific embodiment, the receiving groove 04 is a pre-defined notch, the interior of which is coated with adhesive. This structural design provides a clearly defined filling area for the adhesive, preventing it from overflowing into non-target areas such as the vacuum zone and welding zone 05 during the application process. In this example, the receiving groove 04 is filled with sealant, with a layer thickness of 0.3 mm.

[0031] In a specific embodiment, the upper glass 01 and the lower glass 02 are fixed twice, sequentially by adhesive bonding and welding. In this structural arrangement, adhesive bonding serves as a flexible seal to buffer stress; welding provides a rigid seal, completely preventing air leakage. The dual sealing of adhesive bonding and welding improves the airtightness of the vacuum glass and further extends its service life.

[0032] In a specific embodiment, bonding is performed in the sealing area, and welding is performed in the welding area 05. This structural arrangement, with the sealing and welding processes operating separately, effectively avoids interference between the bonding and welding processes, thus improving the yield rate of vacuum glass products.

Figure 2 As shown, a vacuum glass includes an upper glass layer 01 and a lower glass layer 02. A groove 03 is provided in the center of the surface of the lower glass layer 02. The area formed between the groove 03 and the lower surface of the upper glass layer 01 is a vacuum zone. Receiving grooves 04 are symmetrically arranged on both sides of the groove 03.

[0034] In a specific embodiment, the depth of the groove 03 is greater than or equal to 0.2 mm and less than or equal to 1 / 3 of the thickness of the lower glass layer.

In this example, the welding area 05 and the sealing area are symmetrically arranged about the center of the groove 03. Two welding areas 05 and one sealing area are provided on each side of the groove 03, with the sealing area positioned between the two welding areas 05. The total length of the welding area 05 is 3.2 mm, and the length of the sealing area is 1.6 mm with a depth of 0.3 mm.

[0036] In a specific embodiment, a support column 06 is reserved in the groove 03, and the support column 06 connects the bottom of the groove 03 to the lower surface of the upper glass 01. Through this structural arrangement, the load generated by the vacuum negative pressure is evenly transferred to the lower glass 02, avoiding local stress concentration in the middle of the upper glass 01 caused by its suspended arrangement.

[0037] In a specific embodiment, the support columns 06 have a diameter of 0.3-0.8 mm, a spacing of 30-50 mm, and a height of 0.1-1 mm. Additionally, an elastic buffer layer 10 is provided at the bottom of the groove 03 and between the upper glass 01 and the support columns 06, respectively, and is applied to the upper glass 01 and the bottom of the groove 03. This structural design ensures sufficient support while minimizing the contact area, reducing thermal bridging, balancing structural strength and heat loss, reducing stress concentration, and absorbing the impact of vibration or thermal expansion and contraction. In this example, the support columns are made of alumina ceramic, with a diameter of 0.5 mm, a height of 1 mm, and a matrix arrangement with a spacing of 40 mm × 40 mm. The elastic buffer layer is a 0.1 mm thick sealant.

[0038] In a specific embodiment, a vacuum sensor 07 is also provided within the groove 03. This structure allows for accurate detection of the vacuum level within the vacuum zone.

In this example, the receiving groove 04 is filled with sealant, with a layer thickness of 0.3 mm.

[0042] In a specific embodiment, the upper glass 01 and the lower glass 02 are fixed twice, sequentially by adhesive bonding and welding.

This structural arrangement, with the sealing and welding processes operating separately, effectively avoids interference between the bonding and welding processes, thus improving the yield rate of vacuum glass products.

[0044] Unlike the previous embodiment, the welding area 05 in this embodiment has an additional portion located between the contact surfaces of the upper glass 01 and the lower glass 02 on the outside of the receiving groove 04, while the welding area 05 in the previous embodiment only contained the portion located between the contact surfaces of the upper glass 01 and the lower glass 02 on the inside of the receiving groove 04.
