[0031] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0033] like Figures 1 to 4 As shown, the embodiment of the present application provides a laminated glass, including a first substrate 1, a second substrate 2, an intermediate film 4, and a reflective light-absorbing plate 3 disposed between the first substrate 1 and the second substrate 2. The reflective light-absorbing plate 3 has a material that absorbs light. When a light beam enters the reflective light-absorbing plate, a portion of the light is absorbed and another portion of the light is reflected. The first substrate 1 and the second substrate 2 are both transparent glass plates.

[0034] There are multiple reflective light absorbing plates 3, which are located between the first substrate 1 and the second substrate 2. Both ends of each reflective light absorbing plate 3 are connected to the first substrate 1 and the second substrate 2 respectively, and each reflective light absorbing plate 3 forms a preset angle with the first substrate 1, and there is a gap between two adjacent reflective light absorbing plates 3. The reflective light absorbing plate 3 is also a transparent plate.

[0035] The reflective light-absorbing plate 3 forms a preset angle with the first substrate 1, and the range of the preset angle is set according to the actual application scenario of the laminated glass. The laminated glass can be applied to the front windshield, door glass, side window glass, rearview mirror or sunroof glass, etc. This embodiment will be described by applying the laminated glass to the front windshield 8 of the vehicle.

[0036] The angle between the front windshield 8 of a small car and the bottom plate (horizontal plane) of the vehicle is generally about 30°. Figure 1 and Figure 2 As shown, after the light of the ambient light 7 is reflected by the instrument panel 6 and enters the front windshield 8, the light is reflected by the traditional front windshield 8. Figure 1 The path of the middle dotted line enters the driver's line of sight again, so that the human eye can see the reflection on the front windshield 8. In order to change the path of the light, after the front windshield 8 adopts the laminated glass provided by this embodiment, when the reflective light absorbing plate 3 is parallel to the line of sight of the human eye, the light is reflected by the front windshield 8 according to the Figure 1 The light reflected back along the solid line path will not enter the human eye, so no reflection can be seen on the front windshield 8.

[0037] Among them, because the light enters the light-dense medium from the light-sparse medium when it is incident on the inner side of the front windshield 8 (the side of the first substrate 1 facing the interior of the vehicle), most of the light will not be reflected, but will enter between the first substrate 1 and the second substrate 2, that is, it will be absorbed and reflected by the reflective light-absorbing plate 3.

[0038] Therefore, the reflective light absorbing plate 3 and the first substrate 1 form a preset angle, and the preset angle satisfies that the reflective light absorbing plate 3 is parallel to the line of sight of the human eye. Furthermore, the preset angle range between the reflective light absorbing plate 3 and the first substrate 1 is: 25°~90°. In actual application, it is set according to the angle between the front windshield 8 (side window glass, etc.) and the horizontal direction of the vehicle. When the laminated glass is used as the front windshield 8, the preset angle of a small car can be 30°, and the preset angle of a large truck is close to 90°. When the laminated glass is used as a side window glass, the preset angle can be 70°.

[0039] In a specific implementation, when the laminated glass is installed on a vehicle, the reflective light-absorbing plate 3 is parallel to the angle of the driver's line of sight (±15°), that is, the angle between the reflective light-absorbing plate 3 and the driver's line of sight does not exceed 15°.

[0040] Because the people in the cockpit need to observe the scene outside the car through the front windshield 8, there is a gap between two adjacent reflective light-absorbing plates 3, and the light from the objects outside the car passes through the gap from the second substrate and then enters the car through the first substrate. Only a small part of the light is reflected and absorbed by the reflective light-absorbing plate 3, which will not affect the people in the car to watch the scene outside the car. That is to say, if there is no gap between two adjacent reflective light-absorbing plates 3, when the laminated glass is used as a front windshield, most of the light outside the car will be reflected and absorbed by the reflective light-absorbing plate 3 when it directly passes through the reflective light-absorbing plate 3, causing the objects to appear dark when the people in the car watch the images of the objects outside the car.

[0041] The laminated glass provided in the embodiment of the present application can arrange a plurality of reflective light-absorbing plates 3 between the first substrate 1 and the second substrate 2 by setting a first substrate 1 and a second substrate 2. The reflective light-absorbing plates 3 having light-absorbing materials are arranged to absorb and reflect the light of the interior atmosphere lamp 7, and the reflective light-absorbing plates are arranged at a preset angle with the first substrate 1, so that the light of the interior atmosphere lamp 7 will not be reflected into the human eye, and the human eye will not see the reflection on the laminated glass. The first substrate 1, the second substrate 2 and the plurality of reflective light-absorbing plates 3 are bonded together by providing an intermediate film 4 between the first substrate 1 and the second substrate 2 and between two adjacent reflective light-absorbing plates 3. When the front windshield 8 of the vehicle adopts the laminated glass, the driver will not see the reflection on the front windshield 8, which improves the safety of the driver when driving the vehicle.

[0042] The light absorbing material can be dispersed in the reflective light absorbing plate 3, or can be a reflective absorbing coating provided on the surface of the connecting plate 31. In specific implementation, the reflective absorbing coating is a TiO2 coating or a SiO2 coating. The reflective absorbing coating has a high absorption rate for light. When the incident light enters the connecting plate 31 with the reflective absorbing coating, the absorption rate of the light can reach 85%.

[0043] When light is incident on the connecting plate 31, it first contacts the side of the connecting plate 31 facing the interior of the vehicle, and part of the light is transmitted to the side of the connecting plate 31 facing away from the interior of the vehicle. A reflective absorption coating can be provided on the side of the connecting plate 31 facing the interior of the vehicle, so that a large amount of light will be absorbed when contacting the connecting plate 31, which also saves the material of the reflective absorption coating.

[0044] That is to say, Figure 1 and Figure 2 As shown, the first substrate 1 faces the interior of the vehicle, and the connecting plate 31 has a first surface 311 and a second surface 312 relative to each other along its thickness direction. The first surface 311 faces the first substrate 1, and a reflective light-absorbing coating is provided on the first surface 311. When the light of the ambient light 7 is incident on the connecting plate 31, a large amount of light will be absorbed when it contacts the first surface 311.

[0045] In some embodiments, an intermediate film 4 is provided between the first substrate 1 and the second substrate 2 and between two adjacent reflective light absorbing plates 3, and the first substrate 1, the second substrate 2 and the plurality of reflective light absorbing plates 3 are bonded together by the intermediate film 4. The intermediate film 4 may be a PVB film, and the intermediate film 4 and the reflective light absorbing plates 3 are alternately distributed. An intermediate film is provided between the first substrate and the second substrate and between each two adjacent reflective light absorbing plates, and the intermediate film bonds the first substrate, the second substrate and the plurality of reflective light absorbing plates together.

[0046] In some feasible embodiments, a plurality of reflective light absorbing plates 3 are arranged relatively parallel, and the orthographic projection area of ​​one of two adjacent reflective light absorbing plates 3 on the other is not zero. Figure 1 , that is, the two adjacent projections of the two adjacent reflective light-absorbing plates 3 on the horizontal plane are just connected end to end or partially overlapped in sequence. This prevents the light of the ambient light 7 from being projected onto the second substrate 2 from the gap between the two adjacent reflective light-absorbing plates 3 in the horizontal direction, thereby preventing the formation of a filamentary reflection on the front windshield 8.

[0047] In another embodiment of the present application, a vehicle is provided. The vehicle includes the front windshield 8, and the first substrate 1 faces the interior of the vehicle. The reflective light absorbing plate 3 includes a connecting plate 31 and a reflective light absorbing coating disposed on the connecting plate 31. Figure 2 As shown, the connecting plate 31 has a first surface 311 and a second surface 312 relative to each other along its thickness direction. The first surface 311 faces the first substrate 1. A reflective light-absorbing coating is provided on the first surface 311. When the light of the ambient light 7 is incident on the connecting plate 31, a large amount of light will be absorbed when it contacts the first surface 311.

[0048] like Figure 1 As shown, the vehicle also includes a dashboard cover 5, a dashboard 6 and an ambient light 7. In order to prevent the light of the ambient light 7 from directly entering the human eyes and affecting their comfort, the ambient light 7 is located between the dashboard cover 5 and the dashboard 6 along the height direction of the vehicle, and the light of the ambient light 7 is directed toward the dashboard 6.

[0049] The mood lights 7 are used for decoration and illumination and are usually turned on at night to create a comfortable and relaxing environment. The mood lights 7 can create different types of atmospheres, such as warmth, romance, or technology, by changing color and brightness. These lights can not only illuminate the cabin, but also relieve the driver's fatigue to a certain extent.

[0050] Further, such as Figure 1 As shown, a slope 61 is formed on the instrument panel 6, and along the direction from the front to the rear of the vehicle, the slope 61 is inclined toward the first substrate, and along the direction from the front to the rear of the vehicle, the ambient light 7 and the slope 61 are sequentially distributed. The slope 61 can restrict the direction of the light reflected by the instrument panel 6, so that the light can hit the reflective light absorbing plate 3 and be absorbed.

[0051] Because the second substrate 2 is located outside the vehicle, branches or other objects may hit the second substrate 2, and the thickness of the second substrate 2 is greater than that of the first substrate 1. When the vehicle is in use, there is some space above the dashboard 6 for storing items, and the user will inevitably touch the side of the first substrate 1 located inside the vehicle when taking or placing items, so a wear-resistant layer is provided on the side of the first substrate 1 located inside the vehicle.

[0052] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0053] It should also be noted that, although the present application has been described with reference to the preferred embodiments, various improvements may be made thereto and components thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments of the present application, but includes all technical solutions falling within the scope of the claims.

[0054] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
