Description

Technical Field

[0001] The utility model relates to the field of glass, in particular to a dimming glass and a vehicle. Background Art

[0002] Existing dimming glasses are usually laminated glasses, which include an outer glass layer, an outer adhesive layer, a dimming and color-changing layer, an inner adhesive layer, and an inner glass layer that are sequentially laminated, and an adhesive edge-filling layer is also provided at the edge of the dimming and color-changing layer. Generally, the size of the dimming and color-changing layer of the existing dimming glass is adjusted according to requirements. When there is a large distance between the edge of the dimming and color-changing layer and the edge of the glass plate, it needs to be filled by the adhesive edge-filling layer. This method not only takes a long time, but also wastes the use of adhesives. Moreover, since the area of the dimming and color-changing layer is small, the electrodes connected to the dimming and color-changing layer will be exposed. Therefore, it is also necessary to print a black edge to cover the electrodes of the dimming and color-changing layer, which affects the aesthetics. Summary of the Utility Model

[0047] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the implementation manners and with reference to the drawings.

[0048] Please refer to Figure 1 and Figure 2 , generally, the existing dimming glass adjusts the size of the dimming and color-changing layer according to requirements. When there is a large gap between the edge of the dimming and color-changing layer 10 and the edge of the glass plate 20, it is necessary to fill it up by bonding the edge-filling layer 30. This method not only takes a long time, but also wastes the use of the adhesive. And because the area of the dimming and color-changing layer is small, the electrodes connected to the dimming and color-changing layer will be exposed. Therefore, it is also necessary to print a black edge 40 to cover the electrodes of the dimming and color-changing layer, which affects the aesthetics.

[0049] Based on this, please refer to Figures 3 - 8 , a dimming glass and a vehicle are provided. The vehicle includes the dimming glass; the dimming glass includes an outer glass plate 1, a dimming film 2 and an inner glass plate 3 which are sequentially stacked. At least one side of the dimming film 2 has a vacant area 21 distributed along this side; the distance between the side of the dimming film 2 with the vacant area 21 and the corresponding side of the inner glass plate 3 and / or the outer glass plate 1 is 0-2 mm; the remaining corresponding sides of the dimming film 2 are retracted relative to the other sides of the inner glass plate 3 and / or the outer glass plate 1. Optionally, the thickness of the inner glass plate 3 is 1-4 mm, preferably, the thickness of the inner glass plate 3 is 1.6-2.5 mm.

[0050] It can be understood that by providing a vacant area 21 at at least one edge of the dimming film 2 and setting a spacing of 0 to 2 mm between the edge of the vacant area 21 and the edge of the glass plate, there is no need to fill the edge between the vacant area 21 and the edge of the glass plate. Moreover, since there is no edge filling in this area, there is also no need to print a black edge for covering up defects, which shortens the encapsulation time, improves the encapsulation efficiency of the dimming glass, and enhances the aesthetic appearance. The setting of the vacant area 21 can also be used to fill the adhesive film 8 and improve the sealing effect, thereby protecting the dimming film 2. Herein, the vacant area 21 refers to reducing the thickness of the area near a certain edge of the dimming film 2 to form a step on the dimming film 2.

[0051] In some embodiments, the dimming film 2 has a first edge 22, a second edge 23, a third edge 24, and a fourth edge 25. When the spacing between the second edge 23 and one of the edges of the inner glass plate 3 and / or the outer glass plate 1 is 0 to 2 mm, the retraction distance of the first edge 22 and the third edge 24 is greater than or equal to 0 mm and less than or equal to 2 mm, or the retraction distance of the first edge 22 and the third edge 24 is greater than or equal to 5 mm and less than or equal to 15 mm. Optionally, a spacing of 0 to 2 mm can be formed between one of the first edge 22, the third edge 24, and the fourth edge 25 and the corresponding edge of the inner glass plate 3 and / or the outer glass plate 1; alternatively, a spacing of 0 to 2 mm can be formed between any two or any three of the first edge 22, the second edge 23, the third edge 24, or the fourth edge 25 and the corresponding edge of the inner glass plate 3 and / or the outer glass plate 1. Preferably, the above spacing is 0, that is, the corresponding edge of the dimming film 2 is flush with the corresponding edge on the inner glass plate 3 and / or the outer glass plate 1. Herein, the retraction distance refers to the distance between one edge of the dimming film 2 and the corresponding edge of the inner glass plate 3 and / or the outer glass plate 1. When the retraction distance is greater than 15 mm, the range of the black edge expands, and the visible area of the dimming glass will decrease, affecting the aesthetic appearance of the dimming glass; when the retraction distance is less than 5 mm, the process difficulty during the edge filling operation increases. Therefore, limiting the retraction distance to be between 5 and 15 mm can not only reduce the process difficulty and improve the production efficiency, but also ensure that the dimming glass has a sufficiently large visible area and enhance the aesthetic appearance.

[0052] In some embodiments, the dimming glass is a lifting glass, and the second side portion 23 and the fourth side portion 25 are located in the moving direction of the dimming glass; the dimming glass has a water tangent line 4, and the distance between the water tangent line 4 and the fourth side portion 25 is greater than or equal to 8 mm. The dimming glass further includes a conductive component 5; a power connection area 41 is formed between the fourth side portion 25 and the water tangent line 4, and the power connection area 41 is electrically connected to the conductive component 5. Specifically, the conductive component 5 includes a first electrode 51 and a second electrode 52, and the first electrode 51 and the second electrode 52 are respectively electrically connected to the power connection area 41. Leading out two electrodes from the inward retraction of the fourth side portion 25 under the water tangent line 4 is more convenient for processing. When the dimming glass is a lifting glass, the second side portion 23 is located near the upper edge of the dimming glass, while the fourth side portion 25 is located near the lower edge of the dimming glass. By setting the water tangent line 4, the area formed between the water tangent line 4 and the fourth side portion 25 is a non-visible area and is hidden in the door. Therefore, setting the distance between the water tangent line 4 and the fourth side portion 25 to be greater than or equal to 8 mm can provide sufficient space for the connection of the conductive component 5.

[0053] In some embodiments, the inward retraction distance of the fourth side portion 25 is greater than or equal to 5 mm, so as to facilitate edge filling and reduce the process difficulty.

[0054] In some embodiments, the dimming film 2 includes a first inner adhesive layer 26, a dimming layer 27, and a second inner adhesive layer 28 that are sequentially laminated; the edge of the first inner adhesive layer 26 is flush with the edge of the dimming layer 27, and at least one edge of the dimming layer 27 is retracted relative to the second inner adhesive layer 28 to form the above-mentioned vacant area 21. Optionally, the material of the dimming layer 27 is dye liquid crystal (LC), polymer dispersed liquid crystal (PDLC), or nano-dimming layer 27 (SPD) or electrochromic material (EC). Optionally, the thickness of the dimming layer 27 is 0.12 - 1.0 mm, preferably 0.12 - 0.4 mm.

[0055] In some embodiments, the dimming glass further includes a first outer adhesive layer 6 and a second outer adhesive layer 7; the outer glass sheet 1, the first outer adhesive layer 6, the dimming film 2, the second outer adhesive layer 7, and the inner glass sheet 3 are stacked in sequence; the edges of the first outer adhesive layer 6 are flush with the edges of the outer glass sheet 1. Optionally, the materials of the first outer adhesive layer 6 and the second outer adhesive layer 7 are each at least one of polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), polyurethane (PU), and polyolefin elastomer (POE), wherein the materials of the first outer adhesive layer 6 and the second outer adhesive layer 7 can be different. Preferably, the first outer adhesive layer 6 and the second outer adhesive layer 7 have the same material, such as both being PVB. Optionally, the thicknesses of the first outer adhesive layer 6 and the second outer adhesive layer 7 are 0.38 - 1.14 mm, preferably 0.38 - 0.76 mm. Further, the thicknesses of the first outer adhesive layer 6 and the second outer adhesive layer 7 are 0.39 mm, 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, or 0.75 mm.

[0056] In some embodiments, the first inner adhesive layer 26 includes an adhesive film 261; or, the first inner adhesive layer 26 includes an adhesive film 261 and a conductive film 262, and the adhesive film 261, the conductive film 262, and the dimming layer 27 are stacked in sequence. Among them, the material of the second inner adhesive layer 28 is the same as that of the first inner adhesive layer 26. Preferably, the material of the adhesive film 261 is PET, and the material of the conductive film 262 is ITO. Using PET material or a composite of PET material and ITO to make the first inner adhesive layer 26 can strongly bond with the first outer adhesive layer 6 and improve the structural stability of the dimming glass. When PET is used as the material of the first inner adhesive layer 26 and the second inner adhesive layer 28, the peel force between the inner adhesive layer and the dimming layer 27 ≤ 0.2 N / mm, and the adhesive force is weak. When a composite of PET material and ITO is used to make the first inner adhesive layer 26 and the second inner adhesive layer 28, the tensile strength in the normal direction between the inner adhesive layer and the dimming layer 27 ≥ 3 MPa.

[0057] In some embodiments, the void area 21 is filled with a glue film 8. On the one hand, it can strongly bond the dimming film 2 and the glass sheet. On the other hand, since the dimming film 2 is sensitive to water vapor itself, filling the glue film 8 in the void area 21 is used to seal the dimming film 2.

[0058] In some embodiments, the width of the void area 21 is greater than or equal to 5 mm to expand the filling area of the glue film 8 and improve the sealing performance and adhesive force at the same time.
