[0047] In order to overcome the technical problem that the current laminated glass cannot improve the optical performance of the communication window of the laminated glass while taking into account the overall strength of the laminated glass, the embodiment of the present application provides a laminated glass for vehicles. The laminated glass includes an outer glass plate, an inner glass plate, and a connecting layer. The outer glass plate and the inner glass plate are connected through the connecting layer. The outer glass plate has a first surface facing the outside of the vehicle and a second surface facing the inside of the vehicle. The inner glass plate has a third surface opposite to the second surface and a fourth surface facing the inside of the vehicle; a through hole, the through hole is provided through the third surface and the fourth surface of the inner glass plate; a communication window, in the thickness direction of the laminated glass, the projection of the through hole completely covers the projection of the communication window; a reinforcing plate, the reinforcing plate is provided between the second surface and the third surface; wherein, in the thickness direction of the laminated glass, the projection of the reinforcing plate at least partially covers the projection of the through hole.

[0048] In the present application, a through hole is provided on the inner glass plate of the laminated glass, and in the thickness direction of the laminated glass, the projection of the through hole completely covers the projection of the communication window, so that the thickness of the laminated glass at the communication window is reduced. This can not only reduce the absolute value of the diopter of the communication window, but also the optical signal can be transmitted and / or received by the optical signal acquisition module such as a camera or a lidar without passing through the inner glass plate, thereby reducing the loss of the optical signal when passing through the communication window, and further improving the optical performance of the laminated glass at the communication window; at the same time, by arranging the reinforcing plate between the second surface and the third surface and making the projection of the reinforcing plate at least partially cover the projection of the through hole in the thickness direction of the laminated glass, the reinforcing plate supplements and strengthens the strength of the through hole area on the inner glass plate, so that the overall strength of the laminated glass will not be reduced due to the through hole provided on the inner glass plate, which not only improves the optical performance of the laminated glass at the communication window but also takes into account the overall strength of the laminated glass.

[0049] The technical solutions described in the embodiments of the present application can be applied to various types of vehicles, such as: fuel vehicles, gas vehicles, new energy vehicles, bullet trains, trains, trucks, etc. Among them, the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.

[0050] In the first aspect, as an example, Figure 1 shows a schematic structural diagram of a vehicle 2 provided by an embodiment of the present application. As Figure 1As shown, the vehicle 2 includes a vehicle body 21, an optical signal acquisition module 22, and an interlayer glass 1. The interlayer glass 1 can be disposed at any position on the vehicle body 21. For example, the interlayer glass 1 can be disposed at the front or rear of the vehicle 2 or on both sides of the vehicle 2. The interlayer glass 1 can be used to physically isolate the space of the passenger compartment of the vehicle 2 from the outside space of the vehicle 2. In an embodiment of the present application, the interlayer glass 1 can be used as the front windshield of the vehicle 2 and work together with the optical signal acquisition module 22 (not shown in the figure) of the vehicle 2. In the working area S6 of the optical signal acquisition module 22, the interlayer glass 1 can provide better optical performance support. The optical signal acquisition module 22 can be a camera, a lidar, or the like. In another embodiment of the present application, the interlayer glass 1 can also be used as one or more of the side window glass and the rear windshield of the vehicle 2.

[0051] Figure 2 FIG. 4 shows a front view structural schematic diagram of the interlayer glass 1 disclosed in an embodiment of the present application. Figure 3 shows Figure 2 a partial sectional structural schematic diagram of the interlayer glass 1 in FIG. 4 after being sectioned along A-A. Figure 4 shows Figure 3 an enlarged structural schematic diagram of the interlayer glass 1 at B in FIG. 8. Figure 5 schematically shows Figure 2 an enlarged structural schematic diagram of the interlayer glass 1 at C in FIG. 14.

[0052] Hereinafter, each component of the interlayer glass 1 will be described.

[0053] The thicknesses of the outer glass plate 11 and the inner glass plate 12 vary depending on their compositions and the use of the interlayer glass 1, but are generally 0.5 to 5 mm. The thickness of the inner glass plate 12 is preferably 0.5 to 3.0 mm, more preferably 0.7 to 2.1 mm. The thickness of the outer glass plate 11 is preferably 1.6 mm to 5.0 mm, more preferably 1.8 to 3.5 mm. From the perspective of weight reduction, the total thickness of the outer glass plate 11 and the glass plate 2 is preferably 4.6 mm or less, more preferably 4.2 mm or less, and further preferably 3.6 mm or less.

[0054] The materials of the outer glass plate 11 and the inner glass plate 12 are generally inorganic glasses, such as soda-lime glass (also known as soda-lime silicate glass), aluminosilicate glass, borosilicate glass, lithium aluminosilicate glass, etc. When used as automotive glass, the inorganic glasses selected for the outer glass plate 11 and the inner glass plate 12 are also subjected to strengthening process treatments such as air-cooled strengthening and chemical strengthening. In some other embodiments, the materials of the outer glass plate 11 and the inner glass plate 12 can also be resin polymers such as polymethyl methacrylate (PMMA) or polycarbonate (PC).

[0055] Second aspect, asFigure 2-5 As shown, in the embodiment of the present application, the laminated glass 1 for a vehicle 2 includes: an outer glass plate 11, an inner glass plate 12, and a connection layer 13. The outer glass plate 11 and the inner glass plate 12 are connected by the connection layer 13. The outer glass plate 11 has a first surface S1 facing the outside of the vehicle 2 and a second surface S2 facing the inside of the vehicle 2. The inner glass plate 12 has a third surface S3 opposite to the second surface S2 and a fourth surface S4 facing the inside of the vehicle 2; a through hole 121 that penetrates through the third surface S3 and the fourth surface S4 of the inner glass plate 12; a communication window 16, in the thickness direction Z of the laminated glass 1, the projection T2 of the through hole completely covers the projection T6 of the communication window; a reinforcing plate 14 disposed between the second surface S2 and the third surface S3; wherein, in the thickness direction Z of the laminated glass 1, the projection T1 of the reinforcing plate at least partially covers the projection T2 of the through hole.

[0056] Specifically, the through hole 121 penetrates through the third surface S3 and the fourth surface S4 of the inner glass plate 12, and the number of the through holes 121 can be one or multiple. The shape of the through hole 121 can be a circular, rectangular, trapezoidal or other shape, or a shape adapted to the working area S6 of the optical signal acquisition module of the laminated glass 1. The working area S6 of the optical signal acquisition module will change according to different optical signal acquisition modules 22 on the vehicle 2, and no special limitation is made here. In order to improve the optical performance of the working area S6 of the optical signal acquisition module on the inner glass plate 12, in the thickness direction Z of the laminated glass 1, the area of the projection T2 of the through hole should be greater than or equal to the projection area of the working area S6 of the optical signal acquisition module on the laminated glass 1 on the fourth surface S4.

[0057] In the present application, the connection layer 13 is located between the outer glass plate 11 and the inner glass plate 12 and is used to connect the outer glass plate 11 and the inner glass plate 12. The structure of the connection layer 13 can be an integrally formed structure or a split structure composed of multiple parts spliced together. In the thickness direction Z of the laminated glass 1, the connection layer 13 can be a single-layer structure or a multi-layer overlapping structure, and no special limitation is made here. The material of the connection layer 13 can be polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), or ionomer film (SGP), etc. The connection layer 13 can be partially or entirely disposed between the second surface S2 of the outer glass plate 11 and the third surface S3 of the inner glass plate 12.

[0058] In this application, the communication window 16 refers to the area on the laminated glass 1 through which optical signals can pass. In the thickness direction Z of the laminated glass 1, the projection T2 of the through hole completely covers the projection T6 of the communication window. That is to say, the area of the projection T6 of the communication window is less than or equal to the area of the projection T2 of the through hole. Specifically, in this embodiment, the area of the projection T6 of the communication window is less than or equal to the area of the projection T2 of the through hole.

[0059] In this application, the reinforcing plate 14 is located between the second surface S2 and the third surface S3. The number of the reinforcing plates 14 can be one or more. It should be noted that the thickness direction Z of the laminated glass 1 refers to the direction parallel to the normal vector (not shown in the figure) of the area opposite to the through hole 121 of the inner glass plate 12 on the second surface S2 of the outer glass plate 11. Preferably, the thickness direction Z extends from the fourth surface S4 of the inner glass plate 12 towards the first surface S1 of the outer glass plate 11.

[0060] It should be noted that "the projection T1 of the reinforcing plate at least partially covers the projection T2 of the through hole" means that in the thickness direction Z of the laminated glass 1, the projection of the reinforcing plate 14 and the projection of the through hole 121 may be partially overlapped or completely overlapped. There is a face-to-face relationship between the surface where the reinforcing plate 14 is located and the third surface S3 on the inner glass plate 12 penetrated by the through hole 121. Here, no limitation is made on whether the reinforcing plate 14 and the through hole 121 are connected.

[0061] In this application, by providing a through hole 121 on the inner glass plate 12 of the laminated glass 1 and making the projection T1 of the through hole completely cover the projection T6 of the communication window in the thickness direction Z of the laminated glass 1, the thickness of the laminated glass 1 at the communication window 16 is reduced, and the optical signal can be emitted and / or received by the optical signal acquisition module 22 without passing through the inner glass plate 13, thereby reducing the loss of the optical signal when passing through the communication window 16. Furthermore, the optical performance of the laminated glass 1 at the communication window 16 is improved. At the same time, by arranging the reinforcing plate 14 between the second surface S2 and the third surface S3 and making the projection T1 of the reinforcing plate at least partially cover the projection T2 of the through hole in the thickness direction Z of the laminated glass 1, the strength of the through hole area on the inner glass plate 12 is supplemented and strengthened by the reinforcing plate 14. The overall strength of the laminated glass 1 will not be reduced due to the opening of the through hole 121 on the inner glass plate 12. Both the optical performance of the laminated glass 1 at the communication window 16 is greatly improved and the overall strength of the laminated glass 1 is taken into account.

[0062] Please continue to refer to Figure 4-5 , in some embodiments, in the thickness direction Z of the laminated glass 1, the projection of the reinforcing plate 14 completely covers the projection of the through hole 121.

[0063] Specifically, "the projection of the reinforcing plate 14 completely covers the projection of the through hole 121" means that in the thickness direction Z of the laminated glass 1, both the reinforcing plate 14 and the through hole 121 are projected in the positive or negative direction of the thickness direction Z. At this time, the reinforcing plate 14 will form a projection T1, and the through hole 121 will form a projection T2, and the projection T1 and the projection T2 completely overlap. It can also be understood that in the thickness direction Z of the laminated glass 1, the area of the projection T2 of the through hole 121 is less than or equal to the area of the projection T1 of the reinforcing plate 14.

[0064] By making the projection of the reinforcing plate 14 completely cover the projection of the through hole 121, the area of the projection T2 of the through hole 121 is less than or equal to the area of the projection T1 of the reinforcing plate 14. In the thickness direction Z of the laminated glass 1, when the reinforcing plate 14 is connected to the inner glass plate 12 through the connecting layer 13, the reinforcing plate 14 can not only strengthen the area of the through hole 121 on the inner glass plate 12, but also strengthen the area on the inner glass plate 12 that exceeds the through hole 121. Thus, the reinforcing plate 14 supplements and strengthens the strength of the area on the inner glass plate 12 opposite to the reinforcing plate 14, and the overall strength of the laminated glass 1 will not be reduced due to the opening of the through hole 121 on the inner glass plate 12. At the same time, by opening the through hole 121 on the inner glass plate 12, the projection T1 of the through hole completely covers the projection T6 of the communication window, so that the thickness of the laminated glass at the communication window 16 is reduced, and the optical signal can be emitted and / or received by the optical signal acquisition module 22 without passing through the inner glass plate 13, thereby reducing the loss of the optical signal when passing through the communication window 16. Thus, the optical performance of the inner glass plate 12 at the communication window 16 is improved. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16 but also takes into account the overall strength of the laminated glass 1.

[0065] Figure 6 Shows Figure 3 An enlarged structural schematic diagram of the laminated glass at E in

[0066] Please refer to Figure 4-6 , in some embodiments, the minimum distance between the edge of the reinforcing plate 14 and the edge of the through hole 121 is d1, and d1≥5mm. It should be noted that d1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 15mm, 20mm, etc., and will not be enumerated here.

[0067] By making the minimum distance d1 between the edge of the reinforcement plate 14 and the hole wall 1211 of the through hole 121 ≥ 5 mm, the edge of the reinforcement plate 14 extends beyond the through hole 121. Thus, when the reinforcement plate 14 is connected to the inner glass plate 12 through the connection layer 13 in the thickness direction Z, the reinforcement plate 14 can not only strengthen the area where the through hole 121 is located on the inner glass plate 12, but also strengthen the area of the inner glass plate 12 that extends at least 5 mm beyond the hole wall 1211 of the through hole 121. Further ensuring that the area of the connected region between the reinforcement plate 14 and the inner glass plate 12 is large enough. Thereby further ensuring that the reinforcement plate 14 supplements and strengthens the strength of the area on the inner glass plate 12 opposite to it, so that the overall strength of the laminated glass 1 will not be reduced due to the opening of the through hole 121 on the inner glass plate 12. At the same time, by making the minimum distance d1 between the reinforcement plate 14 and the hole wall 1211 of the through hole 121 ≥ 5 mm, through holes 12 can be opened in the area of the inner glass plate 12 opposite to the reinforcement plate 14. Thus, the thickness of the laminated glass 1 at the communication window 16 is reduced. So that the optical signal can be transmitted and / or received by the optical signal acquisition module 22 without passing through the inner glass plate 13, thereby reducing the loss of light when passing through the communication window 16. Thus, the optical performance of the inner glass plate 12 at the communication window 16 is improved. It not only greatly improves the optical performance of the laminated glass 1 at the communication window 16 but also takes into account the overall strength of the laminated glass 1.

[0068] Please continue to refer to Figure 4-6 , in some embodiments, the laminated glass 1 further includes an adhesive member 131, and the adhesive member 131 is disposed between the second surface S2 of the reinforcement plate 14 and the outer glass plate 11, and the reinforcement plate 14 is connected to the outer glass plate 11 through the adhesive member 131.

[0069] Specifically, the adhesive member 131 refers to the part of the connection layer 13 located between the second surface S2 of the reinforcement plate 14 and the outer glass plate 11. The material of the adhesive member 131 can be polyvinyl butyral (PVB), ethylene - vinyl acetate copolymer (EVA) or ionomer film (SGP), etc. The material of the adhesive member 131 can be different from the material of the connection layer 13. In the thickness direction Z of the laminated glass 1, the adhesive member 131 has opposite upper and lower surfaces, and at least part of the upper surface or the lower surface of the adhesive member 131 is connected to the reinforcement plate 14 and the outer glass plate 11.

[0070] In the thickness direction Z of the laminated glass 1, when the reinforcing plate 14 and the bonding member 13 are projected toward the positive or negative direction of the thickness direction Z, the reinforcing plate 14 forms a projection T1, and the bonding member 13 forms a projection T3 (not shown in the figure), and the projection T1 and the projection T3 partially or completely overlap. It can also be understood that the bonding member 131 is disposed on the region of the reinforcing plate 14 opposite to the second surface S2, and the bonding member 131 can cover a part of the surface of the reinforcing plate 14 in this region or can cover the entire surface of the reinforcing plate 14 in this region.

[0071] By disposing the bonding member 131 of the connecting layer 13 between the reinforcing plate 14 and the second surface S2 of the outer glass plate 11, and making the projection T3 of the bonding member 131 and the projection T1 of the reinforcing plate 14 at least partially overlap in the thickness direction Z of the laminated glass 1, at least a part of the region of the second surface S2 of the outer glass plate 11 opposite to the reinforcing plate 14 can be connected to the reinforcing plate 14 through the bonding member 131, thereby ensuring the strength of the outer glass plate 11 in this region, and further ensuring the overall strength of the laminated glass 1, which not only greatly improves the optical performance of the laminated glass 1 at the communication window 16, but also takes into account the overall strength of the laminated glass 1.

[0072] Please continue to refer to Figure 4 and Figure 6 In some embodiments, in the thickness direction Z of the laminated glass 1, the thickness of the reinforcing plate 14 is D1, the thickness of the bonding member 131 is D2, and 3 / 7 ≤ D1 / D2 ≤ 22.

[0073] Specifically, the range of the thickness D1 of the reinforcing plate 14 can be 0.3 mm to 1.1 mm, the range of the thickness D2 of the bonding member 131 can be 0.05 mm to 0.7 mm, and the range of the thickness D3 of the connecting layer 13 can be 0.6 to 1.5 mm.

[0074] Before the laminated glass 1 is assembled, the thicknesses of the reinforcing plate 14, the bonding member 131, and the connecting layer 13 satisfy: |D1 + D2 - D3| ≤ 0.15 mm.

[0075] After the laminated glass 1 is assembled, the thicknesses of the reinforcing plate 14, the bonding member 131, and the connecting layer 13 satisfy: D1 + D2 ≤ D3; at this time, the ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 3 / 7 ≤ D1 / D2 ≤ 22.

[0076] When the surface curvature radius R (not shown in the figure) of the area where the reinforcing plate 14 is located is less than or equal to 6000 mm, the range of the thickness D1 of the reinforcing plate 14 can be 0.3 mm to 0.7 mm, and the range of the thickness D2 of the bonding member 131 can be 0.05 mm to 0.3 mm. In some embodiments, the thickness D1 of the reinforcing plate 14 is 0.3 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.3 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 1 ≤ D1 / D2 ≤ 6; the thickness D1 of the reinforcing plate 14 is 0.5 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.2 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 2.5 ≤ D1 / D2 ≤ 10; the thickness D1 of the reinforcing plate 14 is 0.7 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.1 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 7 ≤ D1 / D2 ≤ 14. When the surface curvature radius R of the area where the reinforcing plate 14 is located is greater than 6000 mm, the range of the thickness D1 of the reinforcing plate 14 can be 0.3 mm to 1.1 mm, and the range of the thickness D2 of the bonding member 131 can be 0.05 mm to 0.7 mm. In some embodiments, the thickness D1 of the reinforcing plate 14 is 0.3 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.7 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 3 / 7 ≤ D1 / D2 ≤ 6; the thickness D1 of the reinforcing plate 14 is 0.5 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.3 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 5 / 3 ≤ D1 / D2 ≤ 10; the thickness D1 of the reinforcing plate 14 is 0.7 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.2 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 3.5 ≤ D1 / D2 ≤ 14; the thickness D1 of the reinforcing plate 14 is 1.1 mm, and the range of the thickness D2 of the bonding member 131 is 0.05 mm to 0.2 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 satisfies 5.5 ≤ D1 / D2 ≤ 22. Exemplarily, the thickness D1 of the reinforcing plate 14 can be 1.1 mm, and the corresponding thickness D2 of the bonding member 131 can be selected from 0.05 mm to 0.2 mm as 0.05 mm. At this time, the value of D1 divided by D2 is 22. Exemplarily, the thickness D1 of the reinforcing plate 14 can be 0.3 mm, and the corresponding thickness D2 of the bonding member 131 can be selected from 0.05 mm to 0.7 mm as 0.7 mm. At this time, the value of D1 divided by D2 is 3 / 7.

[0077] In some embodiments, the thickness D1 of the reinforcing plate 14 may range from 0.3 mm to 0.7 mm, the thickness D2 of the bonding member 131 may range from 0.05 mm to 0.7 mm, and the sum of the thickness D1 of the reinforcing plate 14 and the thickness D2 of the bonding member 131 is 0.76 mm. The ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 further satisfies 15 / 23 ≤ D1 / D2 ≤ 35 / 3.

[0078] In some embodiments, the thickness D1 of the reinforcing plate 14 is 0.3 mm, the thickness D2 of the bonding member 131 ranges from 0.46 mm, and the ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 is 15 / 23; the thickness D1 of the reinforcing plate 14 is 0.5 mm, the thickness D2 of the bonding member 131 ranges from 0.26 mm, and the ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 is 25 / 13; the thickness D1 of the reinforcing plate 14 is 0.7 mm, the thickness D2 of the bonding member 131 ranges from 0.06 mm, and the ratio of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 is 35 / 3.

[0079] By limiting the ratio range of the thickness D1 of the reinforcing plate 14 to the thickness D2 of the bonding member 131 to the interval of 3 / 7 to 22, the reinforcing plate 14 and the bonding member 131 can ensure that the strength of the reinforcing plate 14 is sufficient to strengthen the area where the through hole 121 is located on the inner glass plate 12 while taking into account the overall thickness of the laminated glass 1. At the same time, the bonding member 131 can also stably connect the reinforcing plate 14 and the second surface S2 of the outer glass plate 11 at the thickness D2, so that the reinforcing plate 14 can supplement and strengthen the strength of the area on the outer glass plate 11 opposite to the reinforcing plate 14, thereby preventing the overall strength of the laminated glass 1 from being reduced due to the opening of the through hole 121 on the inner glass plate 12. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16, but also takes into account the overall strength of the laminated glass 1.

[0080] Figure 7 Shows a magnified structural schematic diagram of the laminated glass 1 disclosed in another embodiment of the present application at Figure 3 at E.

[0081] Please refer to Figure 7 In some embodiments, the connection layer 13 includes a second connection portion 132, and at least a part of the second connection portion 132 is disposed between the reinforcing plate 14 and the third surface S3 of the inner glass plate 12.

[0082] Specifically, the second connecting portion 132 refers to the portion of the connecting layer 13 located between the reinforcing plate 14 and the fourth surface S4 of the inner glass plate 12. In the thickness direction Z of the laminated glass 1, the second connecting portion 132 has opposite upper and lower surfaces, and at least part of the upper or lower surface of the second connecting portion 132 is connected to the reinforcing plate 14 and the inner glass plate 12.

[0083] It should be noted that "between the third surface S3 of the reinforcing plate 14 and the inner glass plate 12" refers to the space formed between the surface of the reinforcing plate 14 close to the third surface S3 of the inner glass plate 12 and the third surface S3. Part or all of the second connecting portion 132 is disposed between the third surface S3 of the reinforcing plate 14 and the inner glass plate 12, that is, part or all of the second connecting portion 132 is accommodated in the above-mentioned space.

[0084] By disposing the second connecting portion 132 of the connecting layer 13 between the third surface S3 of the reinforcing plate 14 and the inner glass plate 12, the area on the third surface S3 of the inner glass plate 12 opposite to the reinforcing plate 14 can be connected to the reinforcing plate 14 through the second connecting portion 132, thereby strengthening the strength of the inner glass plate 12 in this area and preventing the overall strength of the laminated glass 1 from being reduced due to the through hole 121 formed in the inner glass plate 12. While greatly improving the optical performance of the laminated glass 1 at the communication window 16, the overall strength of the laminated glass 1 is also taken into account.

[0085] Please continue to refer to Figure 7 , in some embodiments, the second connecting portion 132 includes a first portion 1321, and the first portion 1321 is disposed between the third surface S3 of the reinforcing plate 14 and the inner glass plate 12.

[0086] It should be noted that "the first portion 1321 is disposed between the third surface S3 of the reinforcing plate 14 and the inner glass plate 12" means that in the thickness direction Z of the laminated glass 1, the surface of the first portion 1321 on the second connecting portion 132 closest to the third surface S3 does not extend beyond the third surface S3 of the inner glass plate 12. That is, the first portion 1321 is accommodated in the space formed between the surface of the reinforcing plate 14 close to the third surface S3 of the inner glass plate 12 and the third surface S3.

[0087] By disposing the first part 1321 of the second connecting portion 132 between the reinforcing plate 14 and the third surface S3 of the inner glass plate 12, the area on the third surface S3 of the inner glass plate 12 opposite to the reinforcing plate 14 can be connected to the reinforcing plate 14 through the first part 1321 of the second connecting portion 132, thereby strengthening the strength of the inner glass plate 12 in this area, so that the overall strength of the laminated glass 1 will not be reduced due to the through hole 121 opened on the inner glass plate 12. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16, but also takes into account the overall strength of the laminated glass 1.

[0088] Figure 8 This is an enlarged structural schematic diagram of the laminated glass 1 disclosed in another embodiment of the present application at Figure 3 E in.

[0089] In some embodiments, the second connecting portion 132 further includes a second part 1322 connected to the first part 1321, wherein the second part 1322 is connected to the reinforcing plate 14, and / or the second part 1322 is connected to the hole wall 1211 of the through hole 121.

[0090] It should be noted that the "second part 1322" refers to the part of the second connecting portion 132 whose projection overlaps with the projection of the through hole 121 in the thickness direction Z. The second part 1322 can be a regular cuboid, cylinder or irregular solid, and no special limitation is made here. The second part 1322 is only connected to the reinforcing plate 14, or the second part 1322 is connected to both the reinforcing plate 14 and the hole wall 1211 of the through hole 121 of the inner glass plate 12. In some embodiments, the second part 1322 is only connected to the reinforcing plate 14. At this time, one end of the second part 1322 is connected to the area on the reinforcing plate 14 opposite to the through hole, and the other end is connected to the third surface S3 of the inner glass plate 12. Please refer to Figure 8 In some embodiments, the second part 1322 is connected to both the reinforcing plate 14 and the hole wall 1211 of the through hole 121 of the inner glass plate 12. At this time, a part of the second part 1322 will enter the through hole 121 and be connected to the hole wall 1211.

[0091] By connecting the second part 1322 of the second connecting part 132 to the reinforcing plate 14 and / or connecting the second part 1322 to the hole wall 1211 of the through hole 121, the contact area between the second connecting part 132, the inner glass plate 12 and the reinforcing plate 14 is increased, thereby enhancing the reinforcing effect of the reinforcing plate 14 on the third surface S3 of the inner glass plate 12 through the second connecting part 132, improving the strength of the inner glass plate 12 at the position where the through hole 121 is formed, and preventing the overall strength of the laminated glass 1 from being reduced due to the formation of the through hole 121 on the inner glass plate 12. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16 but also takes into account the overall strength of the laminated glass 1.

[0092] Please continue to refer to Figure 4 and Figure 6 In some embodiments, the reinforcing plate 14 abuts against the inner glass plate 12. Specifically, "the reinforcing plate 14 abuts against the inner glass plate 12" means that the reinforcing plate 14 is directly connected to the inner glass plate 12, that is, no connecting layer 13 is provided between the reinforcing plate 14 and the third surface S3 of the inner glass plate 12.

[0093] By abutting the reinforcing plate 14 against the inner glass plate 12, no connecting layer 13 is provided between the reinforcing plate 14 and the third surface S3 of the inner glass plate 12, reducing the loss of optical signals when passing through the relative area between the reinforcing plate 14 and the third surface S3, thereby improving the local optical performance of the laminated glass 1 in this area.

[0094] Figure 9 This is an enlarged structural schematic diagram of the laminated glass 1 disclosed in another embodiment of the present application at Figure 3 E.

[0095] Please refer to Figure 9 In some embodiments, the reinforcing plate 14 includes a connected body part 141 and a convex part 142. The convex part 142 extends from the surface of the body part 141 toward the third surface S3 of the inner glass plate 12, and the convex part 142 abuts against the third surface S3.

[0096] Specifically, the body part 141 refers to the part of the reinforcing plate 14 closer to the second surface S2 of the outer glass plate 11. The convex part 142 refers to the part of the reinforcing plate 14 closer to the third surface S3 of the inner glass plate 12, and the convex part 142 is disposed on the surface of the body part 142 opposite to the third surface S3. In some embodiments, the convex part 142 can be a cuboid, a semi-cylinder, or a combined entity with a semi-cylinder on a cuboid, etc. Optionally, the surface of the convex part 142 closer to the third surface S3 of the inner glass plate 12 is a plane.

[0097] By providing a convex portion 142 on the reinforcing plate 14 that is connected to the main body portion 141, the convex portion 142 can strengthen the area where the main body portion 141 is connected to it, further enhancing the strength of the reinforcing plate 14 itself. Thereby enhancing the strengthening effect of the reinforcing plate 14 on the inner glass plate 12, so that the overall strength of the laminated glass 1 will not be reduced due to the through hole 121 being formed on the inner glass plate 12. While greatly improving the optical performance of the laminated glass 1 at the communication window 16, the overall strength of the laminated glass 1 is also taken into account.

[0098] Please continue to refer to Figure 9 , in some embodiments, the connecting layer 13 includes a third connecting portion 133, and the third connecting portion 133 is connected to at least two of the main body portion 141, the convex portion 142, and the third surface S3 of the inner glass plate 12.

[0099] Specifically, the third connecting portion 133 refers to the portion of the connecting layer 13 located between the reinforcing plate 14 and the third surface S3 of the inner glass plate 12. In the thickness direction Z of the laminated glass 1, the third connecting portion 133 has an opposite upper surface and a lower surface, and a part or all of the upper surface or the lower surface of the third connecting portion 133 is connected to the reinforcing plate 14 and the inner glass plate 12.

[0100] It should be noted that "the third connecting portion 133 is connected to at least two of the main body portion 141, the convex portion 142, and the third surface S3 of the inner glass plate 12" means that the third connecting portion 133 is only connected to the main body portion 141 and the third surface S3 of the inner glass plate 12, or the third connecting portion 133 is connected between the main body portion 141 of the reinforcing plate 14, the convex portion 142 of the reinforcing plate 14, and the third surface S3 of the inner glass plate 12. In some embodiments, the third connecting portion 133 is connected to the main body portion 141 and the convex portion 142 of the reinforcing plate 14. At this time, the convex portion 142 can be arranged closer to the through hole 121 than the third connecting portion 133, or the convex portion 142 can be arranged within the third connecting portion 133, that is, the side surface of the convex portion 142 is surrounded by the third connecting portion 133.

[0101] By connecting the third connecting portion 133 to at least two of the main body portion 141, the convex portion 142, and the third surface S3 of the inner glass plate 12, the reinforcing plate 14 can be more connected to the inner glass plate 12, thereby enhancing the strengthening effect of the reinforcing plate 14 on the area where the through hole 121 is located on the inner glass plate 12, so that the overall strength of the laminated glass 1 will not be reduced due to the through hole 121 being formed on the inner glass plate 12. While greatly improving the optical performance of the laminated glass 1 at the communication window 16, the overall strength of the laminated glass 1 is also taken into account.

[0102] Figure 10An enlarged structural schematic diagram of the laminated glass 1 disclosed in another embodiment of the present application at Figure 2 the position C in

[0103] Please continue to refer to Figure 9-10 , in some embodiments, the third connecting portion 133 is connected to both the main body portion 141 of the reinforcing plate 14, the protruding portion 142 of the reinforcing plate 14, and the third surface S3 of the inner glass plate 12. Among them, in the thickness direction Z, the projection of the protruding portion 142 overlaps with the projection of the through hole 121 partially.

[0104] It should be noted that "the projection of the protruding portion 142 overlaps with the projection of the through hole 121 partially" means that in the thickness direction Z, when the protruding portion 142 of the reinforcing plate 14 and the through hole 121 are both projected toward the positive or negative direction of the thickness direction Z, the protruding portion 142 will form a projection T4, and the through hole 121 will form a projection T2, and only a part of the projection T2 and the projection T4 overlap.

[0105] By making the projection of the protruding portion 142 overlap with the projection of the through hole 121 partially in the thickness direction Z, the protruding portion 142 is arranged as close as possible to the through hole 121, so that the space formed between the protruding portion 142 and the main body portion 141 and the third surface S3 of the inner glass plate 12 is as large as possible, which can accommodate more third connecting portions 133, so that the third connecting portion 133 is between the main body portion 141 of the reinforcing plate 14, the protruding portion 142 of the reinforcing plate 14, and the third surface S3 of the inner glass plate 12.

[0106] Figure 11 An enlarged structural schematic diagram of the laminated glass 1 disclosed in another embodiment of the present application at Figure 3 the position B in

[0107] Please refer to Figure 5 , 10 -11. In some embodiments, the laminated glass 1 further includes a shielding layer 15. The shielding layer 15 is arranged around the communication window 16, and the shielding layer 15 covers the edge of the through hole 121.

[0108] Specifically, the shielding layer 15 refers to the light-blocking part on the laminated glass 1. The material of the shielding layer 15 can be selected from one or more of black ceramic ink, brown ceramic ink, black ultraviolet ink, and brown ultraviolet ink. The shielding layer 15 can be formed by screen printing, inkjet printing, etc. The thickness unit of the shielding layer 15 is micrometers, that is, the thickness of the shielding layer 15 can be 5 to 40 micrometers. The shielding layer 15 is disposed around the communication window 16 means that the light-transmitting part within the shielding layer 15 on the laminated glass 1 forms the communication window 16, and the communication window 16 refers to the area on the laminated glass 1 for optical signal transmission. The shielding layer 15 covering the edge of the through hole 121 means that in the thickness direction Z, when the through hole 121 and the shielding layer 15 are projected towards the positive or negative direction of the thickness direction Z, the through hole 121 will form a projection T2, and the shielding layer 15 will form a projection T5. There is only partial overlap between the projection T5 of the shielding layer and the projection T2 of the through hole 121, that is, in the thickness direction Z, the shielding layer 15 covers the edge of the through hole 121.

[0109] By disposing the shielding layer 15 around the communication window 16 and the shielding layer 15 covering the edge of the through hole 121, the shielding layer 15 can shield the edge of the through hole 121 in the thickness direction Z, thereby reducing the influence of light passing through the edge of the through hole 121 on the laminated glass 1 on the connection position between the reinforcement plate 14 and the connection layer 13, thereby reducing the aging speed of the connection layer 13 at this position, and further improving the reliability of the laminated glass 1 in the area opposite to the shielding layer 15.

[0110] Please continue to refer to Figure 11 , in some embodiments, the shielding layer 15 includes a first shielding layer 151, and the first shielding layer 151 is disposed between the second surface S2 and the connection layer 13. The minimum distance between the edge of the first shielding layer 151 and the edge of the reinforcement plate 14 is d2, and d2≥5mm.

[0111] Specifically, the first shielding layer 151 refers to the light-blocking part of the shielding layer 15 located between the second surface S2 of the outer glass plate 11 and the connection layer 13. The minimum distance between the edge of the first shielding layer 151 and the edge of the reinforcement plate 14 being d2 means the distance between the boundary line of the part of the first shielding layer 151 closest to the through hole 121 and the boundary line of the part of the reinforcement plate 14 farthest from the through hole 121.

[0112] By disposing the first shielding layer 151 between the second surface S2 and the connection layer 13 and making the minimum distance d2 between the edge of the first shielding layer 151 and the edge of the reinforcement plate 14 satisfy d2≥5mm. The first shielding layer 151 shields the edge of the reinforcement plate 14 in the thickness direction Z, thereby reducing the influence of light on the connection position between the reinforcement plate 14 and the connection layer 13, and further improving the reliability of the laminated glass 1 in the area opposite to the first shielding layer 151.

[0113] Please continue to refer to Figure 11 , in some embodiments, the shielding layer 15 further includes a second shielding layer 152, and the second shielding layer 152 is disposed on the third surface S3 or the fourth surface S4.

[0114] Specifically, the second shielding layer 152 refers to the light-blocking portion of the shielding layer 15 located on the third surface S3 or the fourth surface S4 of the inner glass plate 12. Optionally, the edge of the second shielding layer 152 is connected to the outer contour of the through hole 121 on the third surface S3 or the fourth surface S4.

[0115] By providing the second shielding layer 152 on the third surface S3 or the fourth surface S4, the shielding effect of the shielding layer 15 on the edge of the reinforcing plate 14 in the thickness direction Z is improved.

[0116] In some embodiments, the material of the reinforcing plate 14 is at least one of glass or a polymer film. The glass includes at least one of soda-lime glass, aluminosilicate glass, and borosilicate glass. The polymer film includes at least one of a PET polyester film, a TPU polyurethane film, or a BOPP polypropylene film.

[0117] Specifically, in some embodiments, the material of the reinforcing plate 14 is selected from soda-lime glass (also known as soda-lime silicate glass), aluminosilicate glass, borosilicate glass, the material of the reinforcing plate 14 is a PET polyester film (Polyethylene Terephthalate, PET), a TPU polyurethane film (Thermoplastic Polyurethane, TPU), or a BOPP polypropylene film (Biaxially Oriented Polypropylene, BOPP). The reinforcing plate 14 is transparent. In the case where the material of the reinforcing plate 14 is aluminosilicate glass, optionally, the medium-aluminum glass and high-aluminum glass with an alumina content of more than 4% in the aluminosilicate glass. In some embodiments, the material of the reinforcing plate 14 is selected from multiple of soda-lime glass, aluminosilicate glass, borosilicate glass, PET polyester film, TPU polyurethane film, or BOPP polypropylene film. For example, the reinforcing plate 14 can be made of a composite material of aluminosilicate glass and a PET polyester film, and so on. This specification will not enumerate them all.

[0118] By selecting the material of the reinforcing plate 14 as one or more of soda-lime glass, aluminosilicate glass, borosilicate glass, PET polyester film, TPU polyurethane film, or BOPP polypropylene film, the material of the reinforcing plate 14 can flexibly select one or a combination of the above materials according to the strength requirements of the inner glass plate 12 at the through-hole 121. Thus, the overall strength of the laminated glass 1 will not be reduced due to the opening of the through-hole 121 on the inner glass plate 12. While greatly improving the optical performance of the laminated glass 1 at the communication window 16, the overall strength of the laminated glass 1 is also taken into account.

[0119] In some embodiments, the material of the reinforcing plate 14 is physically tempered glass or chemically tempered glass.

[0120] The reinforcing plate 14 can be physically tempered glass. The physically tempered glass can be semi-tempered glass with a surface stress of 24 - 69 Mpa, or fully tempered glass with a surface stress of 69 - 200 Mpa. Further, the reinforcing plate 14 can also be chemically tempered glass with a surface stress of 100 - 2000 Mpa.

[0121] Physical tempering is to uniformly heat ordinary flat glass in a heating furnace to a temperature close to the softening temperature of the glass, eliminate the internal stress of the glass through its own deformation, then remove the glass from the heating furnace, and use a multi-nozzle to blow high-pressure cold air onto the two large surfaces of the glass to quickly and uniformly cool it to room temperature, then physically tempered glass can be obtained. Since the surface of the glass cools and hardens first during rapid cooling, but the inside of the glass has not completely cooled, the hardened surface layer prevents the volume contraction of the inside of the glass, and finally makes the surface layer of the glass in a compressive state, and a tensile stress that is overall balanced with the compressive stress is generated inside it.

[0122] Chemical tempering treatment is to place the glass in a molten alkali salt to exchange the ions in the glass surface layer with the ions in the molten salt. Due to the volume change of the exchanged ions, compressive stress can be formed on the two surfaces of the glass, and tensile stress can be formed inside, so as to achieve the effect of improving the strength of the glass.

[0123] By selecting the material of the reinforcing plate 14 as physically tempered glass or chemically tempered glass, the strengthening effect of the reinforcing plate 14 on the through-hole 121 is ensured, and the overall strength of the laminated glass 1 will not be reduced due to the opening of the through-hole 121 on the inner glass plate 12. While improving the optical performance of the laminated glass 1 at the communication window 16, the overall strength of the laminated glass 1 is also taken into account.

[0124] Figure 12 For the laminated glass 1 disclosed in another embodiment of this application in Figure 3 an enlarged structural schematic diagram at E.

[0125] Please refer to Figure 12, in some embodiments, the reinforcing plate 14 includes at least two reinforcing sub-pieces 143, and in the thickness direction Z of the laminated glass 1, the at least two reinforcing sub-pieces 143 are stacked.

[0126] Specifically, "the reinforcing plate 14 includes at least two reinforcing sub-pieces 143" means that the reinforcing plate 14 includes two or more reinforcing sub-pieces 143, and the multiple reinforcing sub-pieces 143 can have the same thickness or different thicknesses. In some embodiments, the multiple reinforcing sub-pieces 143 are made of the same material, which is one of soda-lime glass, aluminosilicate glass, borosilicate glass, PET polyester film, TPU polyurethane film, or BOPP polypropylene film. In some embodiments, the multiple reinforcing sub-pieces 143 are made of different materials. The materials of the multiple reinforcing sub-pieces 143 are a combination of two or three or more of soda-lime glass, aluminosilicate glass, borosilicate glass, PET polyester film, TPU polyurethane film, or BOPP polypropylene film. Taking the number of the reinforcing sub-pieces 143 as three as an example, the material of one of the three reinforcing sub-pieces 143 can be aluminosilicate glass, and the materials of the other two can be PET polyester film or PET polyester film, or the materials of the other two can both be PET polyester film. And so on, this specification will not list them all.

[0127] It should be noted that "in the thickness direction Z of the laminated glass 1, the at least two reinforcing sub-pieces 143 are stacked" means that in the thickness direction Z of the at least two reinforcing sub-pieces 143, one reinforcing sub-pieces 143 is placed on top of another, and the adjacent two reinforcing sub-pieces 143 can be directly connected or indirectly connected through an adhesive material. The projections of the multiple reinforcing sub-pieces 143 in the thickness direction Z can completely overlap or partially overlap, and no special limitation is made here. Preferably, the projections of the multiple reinforcing sub-pieces 143 in the thickness direction Z completely overlap. In some embodiments, the number of the reinforcing sub-pieces 143 is two or more, and each reinforcing sub-pieces 143 includes two opposite fifth surfaces S7, and the fifth surface S7 is the largest surface on the reinforcing sub-pieces 143, and an adhesive material is provided between at least two adjacent fifth surfaces S7 of the reinforcing sub-pieces 143. Taking the number of the reinforcing sub-pieces 143 as three as an example, the adhesive material can be provided only in one layer between the fifth surfaces S7 of the two closest reinforcing sub-pieces 143, and the fifth surface S7 on the other reinforcing sub-pieces 143 is not provided. In some embodiments, an adhesive material is provided between the two opposite fifth surfaces S7 of different reinforcing sub-pieces 143 among the multiple reinforcing sub-pieces 143. That is, among the multiple reinforcing sub-pieces 143, an adhesive material is provided between the fifth surface S7 of each different reinforcing sub-pieces 143 and the fifth surface S7 of the closest reinforcing sub-pieces 143 opposite thereto. The adhesive material can be polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), or ionomer film (SGP), etc.

[0128] By setting the reinforcing plate 14 into at least two reinforcing sub-pieces 143 and stacking a plurality of reinforcing sub-pieces 143 in the thickness direction Z of the laminated glass 1, a connecting layer 13 is provided between two opposite fifth surfaces S7 on at least two reinforcing sub-pieces 143, so that the acting force received by the inner glass plate 12 in the area opposite to the through hole 121 can be transmitted layer by layer through two or more reinforcing sub-pieces 143 and the connecting layer 13, thereby enabling the inner glass sheet 12 to bear a greater acting force in this area, and further preventing the overall strength of the laminated glass 1 from being reduced due to the opening of the through hole 121 on the inner glass plate 12. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16, but also takes into account the overall strength of the laminated glass 1.

[0129] Please refer to Figure 9 and Figure 10 , in some embodiments, a chamfer 144 is provided at the edge of the reinforcing plate 14, and the chamfer 144 has a radius r, where r ≥ 5 mm.

[0130] Specifically, a chamfer 144 can be provided at the intersection of two adjacent surfaces on the reinforcing plate 14. Optionally, chamfers 144 are provided at the intersections of all adjacent two surfaces on the reinforcing plate 14.

[0131] By providing a chamfer 144 at the edge of the reinforcing plate 14 away from the through hole 121 and making the radius of the chamfer 144 greater than 5 mm, when the reinforcing plate 14 is connected to the outer glass plate 11 and the inner glass sheet 12, the force at the intersection of two adjacent surfaces can be more uniform, so that the reinforcing plate 14 can bear a greater acting force, and further preventing the overall strength of the laminated glass 1 from being reduced due to the opening of the through hole 121 on the inner glass plate 12. This not only greatly improves the optical performance of the laminated glass 1 at the communication window 16, but also takes into account the overall strength of the laminated glass 1.

[0132] The absolute value of the diopter of the laminated glass 1 at the communication window 16 is S, where S ≤ 100 mdpt or S ≤ 60 mdpt.

[0133] The absolute value of the square extreme difference of the diopter of the laminated glass 1 at the communication window 16 is Q, where Q ≤ 60 mdpt or Q ≤ 50 mdpt.

[0134] For the optical transmission area on the automotive windshield, the requirement regarding diopter (the maximum allowable light distortion value) is mostly less than 400 mdpt. For some high-end vehicle models, the requirement is no greater than 200 mdpt. The diopter of traditional glass combinations is generally greater than 200 mdpt. For the structure of ordinary laminated glass 1, the diopter capacity of the communication window 16 can generally achieve a maximum of less than 150 mdpt at most, and it is difficult to further meet the requirement of less than 100 mdpt. For example, referring to Table 1 and Table 2 below, in the comparative example of this application, the product combination using a certain model of laminated glass 1 is 2.1 mm + 0.76 mm + 2.1 mm (the thickness of the outer glass plate 11 + the thickness of the bonding layer 13 + the thickness of the inner glass plate 12). At this time, no through hole 121 was dug in the inner glass plate 12 for testing. Measured using the LABSCAN-SCREEN system of ISRAVISION company, the maximum diopter of the optical window was detected under the condition that the filter parameters for the horizontal diopter were 3 / 2 / 1 30 / 5 / 5 and the detection angle was 24.5°. The horizontal diopter results in Table 1 below were obtained. Among them, the detection results of the absolute values of the horizontal diopters in the product combination of the comparative example were all ≥ 100 mdpt. Although it can meet the usage requirements of some cameras, at the same time, since it is necessary to ensure a low horizontal diopter value in the communication window 16, more stringent precision control is also required during the manufacturing processes such as heating, forming, and laminating of the laminated glass 1 as a whole. This leads to a decrease in the yield rate and an increase in production costs. Among them, the horizontal direction refers to the direction perpendicular to the driving direction of the vehicle in the horizontal plane direction relatively parallel to the ground when the glass is installed on the vehicle, and the horizontal diopter refers to the diopter value measured approximately along the horizontal direction on the curved surface of the glass.

[0135] In this application, however, a laminated glass 1 with a product combination of 2.1 mm + 0.1 mm + 0.7 mm (the thickness of the outer glass plate 11 + the thickness of the bonding member 131 in the communication window area + the thickness of the reinforcement sheet 14) in the communication window area is used as an example. Measured using the LABSCAN-SCREEN system of ISRAVISION company, the maximum horizontal diopter of the optical window was detected under the condition that the filter parameters for the horizontal diopter were 3 / 2 / 1 30 / 5 / 5 and the detection angle was 24.5°. The detection results are shown in Table 2 respectively. The absolute value of its horizontal diopter can easily meet the requirement of ≤ 100 mdpt, and further can meet the requirements of ≤ 60 mdpt, and even ≤ 50 mdpt; the absolute value of the horizontal square extreme difference of its diopter can easily meet the requirement of ≤ 60 mdpt, and further can meet the requirements of ≤ 50 mdpt, and even ≤ 40 mdpt; therefore, the laminated glass 1 has good local optical performance at the communication window 16.

[0136] Prepare two pieces of silicate glass with a thickness of 2.1 mm. Bend each piece of silicate glass according to the bending process of automotive glass, such as self-weight bending process or pressing bending process. Then, perform lamination treatment, initial pressing treatment, and high-pressure treatment on the two bent silicate glasses and a piece of 0.76 mm PVB (interlayer 13) to form the laminated glass 1 of Comparative Examples 1-10. Measure and calculate the measured data of the horizontal diopter of the communication window 16 and the horizontal square extreme difference of the optical window of Comparative Examples 1-10, and record the measurement results in Table 1.

[0139] Prepare two pieces of silicate glass with a thickness of 2.1 mm. Bend each piece of silicate glass according to the bending process of automotive glass, such as self-weight bending process or pressing bending process. Then, perform lamination treatment, initial pressing treatment, and high-pressure treatment on the two bent silicate glasses and a piece of 0.76 mm PVB (interlayer 13) to form the laminated glass 1 of Examples 1-10. Measure and calculate the measured data of the horizontal diopter of the communication window 16 and the horizontal square extreme difference of the optical window of Examples 1-10, and record the measurement results in Table 2.

[0141] Example Horizontal diopter (mdpt) Horizontal square extreme difference (mdpt) 1 -45.3 34.3 2 -40.4 37.6 3 -42.7 37.5 4 -42.5 34.9 5 -47 43.3 6 -47.3 38.6 7 -41.8 36.8 8 -42.5 38.6 9 -49.9 48.1 10 -44.4 36.2

[0142] Among them, the data in Table 1 and Table 2 are measured by the LABSCAN-SCREEN system of ISRAVISION Company. The horizontal diopter measures the maximum diopter in the horizontal direction of the optical window with a filter parameter of 3 / 2 / 1 30 / 5 / 5 and a detection angle of 24.5°. The horizontal square extreme difference divides the optical window into several 15 mm * 15 mm squares, with a filter parameter of 3 / 2 / 1 30 / 5 / 5 and a detection angle of 24.5°. Detect the maximum diopter and minimum diopter in the horizontal direction of each square, calculate the difference between the maximum diopter and the minimum diopter as the extreme difference of each square, and take the maximum value among the extreme differences of all squares as the horizontal square extreme difference. The positive and negative values of the horizontal diopter in Table 1 and Table 2 only represent the direction of optical deformation. A positive number indicates that the direction of optical deformation is convex outward, and a negative number indicates that the direction of optical deformation is concave inward. The absolute value of the horizontal diopter represents the degree of optical deformation, and the larger the absolute value, the greater the degree of optical deformation.
