Description

Technical Field

[0001] This utility model relates to the field of glass technology, and in particular to a vacuum glass that is easy to fix a getter. Background Technology

[0002] A vacuum glass structure comprises at least two glass plates: an upper glass plate and a lower glass plate, as well as an intermediate support structure positioned between the upper and lower glass plates. In the vacuum glass manufacturing process, after the upper and lower glass plates are joined together, they are welded together in a vacuum environment to ultimately form a vacuum glass with a high-vacuum internal cavity.

[0003] To maintain a high vacuum level within the vacuum glass cavity over a long period, a getter is placed in the cavity between the upper and lower glass plates during manufacturing to absorb residual gas and any subsequently released gas. Traditionally, the getter is placed in a pre-machined getter reservoir on one of the glass plates to hold it in place. However, during the lamination process, collisions and vibrations can cause the getter to detach from the reservoir, affecting subsequent activation and vacuum maintenance. Furthermore, machining the reservoir requires cutting grooves into the vacuum glass, impacting its aesthetics, increasing manufacturing complexity and production costs, and reducing structural strength. Therefore, this method of securing the getter has significant drawbacks.

[0004] Based on the above, for example, patent CN221096306U discloses a vacuum glass that uses two metal connectors located at both ends of the getter and is fixedly connected to the getter by welding or riveting. Actual research has shown that the high temperature during spot welding easily degrades the getter's performance. Another example is patent CN221053530U, which proposes compressing the getter by bending it. However, actual research has found that bending or stamping easily contaminates the getter, affecting its performance.

[0005] Therefore, in order to address the shortcomings in the fixation process of the getter in the vacuum glass, it is necessary to further optimize and improve the fixation structure of the getter used in the vacuum glass. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum glass that is easy to fix the getter, so as to solve the technical problem of optimizing the fixation structure for the getter.

[0007] The vacuum glass of this invention, which facilitates the fixation of getter, is achieved as follows:

[0008] A vacuum glass for easy fixation of a getter includes: an upper glass plate, a lower glass plate, and a plurality of support columns of equal height disposed between the upper and lower glass plates, and at least one getter assembly; wherein

[0009] The getter assembly includes a support for fixing between the upper and lower glass panes and a getter disposed within the support; wherein

[0010] The support includes at least a pair of spaced-apart edging portions for holding a pair of oppositely distributed side ends of a getter, such that at least one notch is formed between the pair of edging portions; and each of the edging portions is at the same height as the support column.

[0011] In an optional embodiment of this invention, the four periphery edges of the upper and lower glass are connected and fixed by a sealing agent.

[0012] In an optional embodiment of this invention, the getter has an elongated strip-shaped structure; and

[0013] Each of the aforementioned edge portions is a U-shaped body located at the width end of the getter.

[0014] In an optional embodiment of this invention, the width of each edge portion corresponding to the width direction end of the getter is 0.1 to 5 mm.

[0015] In an optional embodiment of this invention, the thickness of each of the edging portions is 0.1 to 5 mm.

[0016] In an optional embodiment of this invention, the support base further includes a support portion connected to a pair of edge portions and located at one longitudinal end of the getter facing the upper or lower glass plate.

[0017] In an optional embodiment of this utility model, two getter assemblies are provided between the upper glass plate and the lower glass plate; and both getter assemblies are arranged adjacent to one side edge of the upper glass plate and the lower glass plate.

[0018] In optional embodiments of this invention, the support base is made of metal or inorganic non-metallic material.

[0019] By adopting the above technical solution, this utility model has the following beneficial effects: The vacuum glass of this utility model, which facilitates the fixation of the getter, uses a support base to clamp the getter, reliably confining it between the upper and lower glass plates. The support base, being at the same height as the support column, allows the upper and lower glass plates to clamp the support base, preventing it from wobbling between the upper and lower glass plates. This structure eliminates the need for pre-fabricated grooves on the upper and / or lower glass plates, and also eliminates the need for welding the getter, thus simplifying the fixation process while ensuring reliable and stable performance of the getter.

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] Please see Figures 1 to 4 As shown, this embodiment provides a vacuum glass that facilitates the fixation of a getter, comprising: an upper glass plate 11, a lower glass plate 12, and a plurality of support columns 14 of equal height disposed between the upper and lower glass plates, and at least one getter assembly. It is understood that the four perimeters of the upper and lower glass plates are connected and fixed by a sealing agent 13.

[0027] In conjunction with the accompanying drawings, one optional scenario is illustrated where two getter assemblies are disposed between the upper glass plate 11 and the lower glass plate 12; and both getter assemblies are arranged adjacent to one side edge of the upper glass plate 11 and the lower glass plate 12. Alternatively, the two getter assemblies can be arranged separately, corresponding to two different side edges of the upper glass plate 11 and the lower glass plate 12.

[0028] More specifically, the getter assembly used in this embodiment includes a support for fixing between the upper and lower glass and a getter 15 disposed within the support. The support may be made of, for example, but not limited to, inorganic non-metallic materials such as metal or glass ceramic.

[0029] The support base includes at least a pair of spaced-apart edging portions 16 for holding a pair of oppositely distributed side ends of the getter 15, such that at least one notch A is formed between the pair of edging portions 16; and each edging portion 16 is at the same height as the support column 14. The notch A is designed primarily to facilitate gas flow, allowing the getter 15 to absorb residual gas in the cavity formed between the upper glass plate 11 and the lower glass plate 12, as well as subsequently released gas, which can then be absorbed by the getter 15.

[0030] Based on the above structure, in detail, as an example of an optional case, the getter 15 is a long strip structure; and each edge portion 16 is a U-shaped body located at the width end of the getter 15. That is, the edge portion 16 can simultaneously form a portion of a width end of the getter 15 and a pair of length ends perpendicular to the width end, and this pair of length ends are perpendicular to the end faces of the upper glass plate 11 and the lower glass plate 12. In this case, for the getter 15, not only are notches A formed at the two length ends of the getter 15 facing the upper glass plate 11 and the lower glass plate 12, but notches A are also formed at the two length ends of the getter 15 perpendicular to the upper glass plate 11 and the lower glass plate 12 and located between the pair of edge portions 16.

[0031] It should be noted that, in optional implementations, the width of each edge portion 16 corresponding to the width direction end of the getter 15 is 0.1 to 5 mm, preferably 0.5 to 2 mm, and the thickness of each edge portion 16 is 0.1 to 5 mm, preferably 0.5 to 2 mm.

[0032] Based on the above, the following improvements can be made:

[0033] The support also includes a support portion 17 connected to a pair of edge portions 16 and located at one longitudinal end of the getter 15 facing the upper glass plate 11 or the lower glass plate 12. Thus, for the getter 15, only one of its two longitudinal ends facing the upper glass plate 11 and the lower glass plate 12 has a notch A.

[0034] In summary, for the vacuum glass of this embodiment that facilitates the fixation of the getter, the getter 15 is clamped by the provided support base, ensuring that the getter 15 is reliably confined between the upper glass plate 11 and the lower glass plate 12 while clamped. The support base, being at the same height as the support column 14, allows the upper and lower glass plates 11 and 12 to clamp the support base, preventing the support base from wobbling between the upper and lower glass plates 11 and 12. With this structure, fixing the getter 15 does not require pre-fabricating grooves on the upper and / or lower glass plates 11 or 12, nor does it require welding the getter 15. Therefore, the fixing process of the getter 15 is simplified, while ensuring the reliable and stable performance of the getter 15.
