If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] See also Figure 1 , is a skylight glass 100 shown in an embodiment of the present application, which includes an outer glass plate 10, a light regulating structure layer 20 and an inner glass plate 30, and the light regulating structure layer 20 is laminated between the inner glass plate 30 and the outer glass plate 10. That is, the light regulating structure layer 20 is installed between the inner glass plate 30 and the outer glass plate 10 as an intermediate layer.

[0040] According to actual needs, the outer glass plate 10 and the inner glass plate 30 are independently arranged, and can adopt the structure of single-layer glass plate, double-layer glass plate or more-layer glass plate. For example, in the present application, the outer glass plate 10 and the inner glass plate 30 both adopt the structure of single-layer glass plate.

[0041] The outer glass plate 10 and the inner glass plate 30 are generally made of inorganic glass and / or organic glass materials, such as soda-lime glass, borosilicate glass, aluminosilicate glass, polymethacrylate, polycarbonate, etc., and soda-lime glass is preferably used.

[0042] The thickness of the outer glass plate 10 and the inner glass plate 30 are both 1.6 mm to 6.0 mm, and the visible light transmittance is 2% to 90%, for example, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0043] Alternatively, in other optional embodiments, the outer glass plate 10 and the inner glass plate 30 may also be laminated glass. For example, the laminated glass is composed of an inner glass sheet, an outer glass sheet and an intermediate interlayer. The intermediate interlayer may be a hollow layer or a composite multilayer film structure. When a composite multilayer film structure is used, it may be PDLC (polymer dispersed liquid crystal), EC (Electrochromic-EC), LC (liquid crystal), etc., which have a dimming function and may also have an ambient light function.

[0044] The thickness of the inner glass sheet is 0.7 mm to 3.0 mm, and the visible light transmittance is 2% to 90%, for example 2%, 5%, 10%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc.

[0045] Please continue reading Figure 2 and Figure 3 In addition, the light regulating structure layer 20 in the present application includes a light control unit 21a, and the light control unit 21a includes a light-transmitting portion 211a and a light-controlling portion 212a connected to each other. The light-controlling portion 212a is made of a photosensitive material, and the light-controlling portion 212a is used to block sunlight of a specific incident angle that reaches a preset light intensity condition.

[0046] For example, the photosensitive material used in the light control part 212a may be, but is not limited to, a silver halide system, diarylethenes, fulgide, spiropyran, spirooxanes, azo compounds, and related heterocyclic compounds. Under the irradiation of sunlight at a specific incident angle under a preset light intensity condition, the visible light transmittance of the light control part 212a is less than 0.5%, so as to ensure the shielding effect of sunlight directly hitting the eyes of rear passengers.

[0047] The light-transmitting portion 211 a is a transparent thermoplastic material, such as TPU, PVB, PVC, etc., and its visible light transmittance is 2% to 90%, for example, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc.

[0048] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the sunroof glass 100 of this solution is applied to the sunroof assembly of the automobile, and the sunroof glass 100 is specifically composed of an outer glass plate 10, a light regulating structure layer 20 and an inner glass plate 30 stacked together, wherein the light regulating structure layer 20 includes a light control unit 21a, and the light control unit 21a is composed of a light-transmitting portion 211a and a light-controlling portion 212a connected together; when the automobile is driving in an environment with strong light, a part of the sunlight at a specific incident angle that reaches a preset light intensity condition is irradiated onto the light-controlling portion 212a, and the light-controlling portion made of a photosensitive material 212a will gradually turn dark under the influence of light, and as the light intensity increases, the light control part 212a will become opaque, thereby blocking the sunlight that directly hits the eyes of the rear passengers, thereby preventing the rear passengers from feeling uncomfortable such as glare and glare. At the same time, the set light-transmitting part 211a can allow the sunlight other than the above-mentioned light intensity conditions and the specific incident angle to pass through the sunroof glass 100 normally and enter the car, meeting the vision needs of the people in the car to observe the objects outside the car through the sunroof glass 100, and keeping a bright light environment in the car, thereby greatly improving the riding comfort of the rear passengers.

[0049] It should be noted that the sunlight of a specific incident angle mentioned in the present application specifically refers to the sunlight incident into the vehicle in a direction perpendicular to the sunroof glass.

[0050] It should be noted that the solution of the present application should not be limited to skylight glass, but can also be front windshield, side windshield, corner window glass, rear windshield, etc., and even architectural glass, home glass, etc.

[0051] It should be noted that the preset light intensity condition described in the present application is that the light intensity value is greater than or equal to 3500LX. That is, when the light intensity value of the sunlight irradiating the light control part 212a is greater than or equal to 3500LX, the light control part 212a immediately begins to darken in color, and the light intensity value of 3500LX is just the light intensity condition that is uncomfortable for human eyes.

[0052] Preferably, when the light intensity is greater than or equal to 4000 LX, the light control portion 212a will change color significantly, and as the light intensity increases, the color of the light control portion 212a will continue to deepen until it becomes opaque. The light intensity of 4000 LX is the light intensity condition at which the human eye begins to have difficulty receiving sunlight (i.e., the eye cannot open normally when facing the sunlight).

[0053] It should be noted that when the light intensity of the sunlight incident at a specific incident angle drops below 3500 LX, the light control portion 212a will gradually return to a transparent and visible state. In other words, although the skylight glass 100 is in a strong light environment, as long as the light intensity of the sunlight incident at a specific incident angle on the light control portion 212a does not reach 3500 LX, the light control portion 212a always remains in a transparent and visible state.

[0054] Please continue reading Figure 2 and Figure 3 On the basis of the above embodiment, a plurality of light control units 21a are preferably provided, and the plurality of light control units 21a are sequentially connected and arranged side by side to form a light control layer 21; in any two adjacent light control units 21a, the light-transmitting portion 211a and the light-controlling portion 212a are connected side by side in a direction parallel to the surface of the inner glass plate 30. That is, each two adjacent light-transmitting portions 211a are connected by a light-controlling portion 212a, and each two adjacent light-controlling portions 212a are connected by a light-transmitting portion 211a.

[0055] For example, when the skylight glass 100 is a rectangular structure, a plurality of light control units 21a can be arranged side by side along the length direction of the skylight glass 100, or can be arranged side by side along the width direction of the skylight glass 100, and the selection can be made according to actual needs. In this embodiment, by setting the light control layer 21, different parts of the skylight glass 100 have different light control units 21a. Since the height of the heads of different rear passengers of different heights or sitting postures are different from the skylight glass 100, the incident positions of the sunlight that forms a direct relationship with the eyes of different rear passengers on the skylight glass 100 are also different; in this way, the light control units 21a at different positions can block the sunlight of a specific incident angle that reaches the preset light intensity condition and is incident from different positions of the skylight glass 100, thereby providing good anti-glare and glare effects for different rear passengers.

[0056] It is necessary to explain that sunlight with a specific incident angle that reaches a preset light intensity condition can be identified as sunlight with an uncomfortable viewing angle. Figure 3 As shown in the figure, the star-shaped figure on the left represents the sun, which is used to emit sunlight; the ellipse on the right represents the viewing angle of the rear passengers; the oblique line between the star-shaped figure and the ellipse represents sunlight with an uncomfortable viewing angle.

[0057] Optionally, the specific incident angle θ is in the range of 40° to 80°. For example, θ is 40°, 50°, 55°, 60°, 70°, 75°, 80°, etc. Further, the specific incident angle θ is selected to be 50° to 70°, which can meet the requirements of most passengers of different heights sitting in the rear row of the vehicle, and the light control unit 212a effectively blocks the uncomfortable sunlight of various incident angles, thereby preventing passengers from feeling uncomfortable, such as glare, etc.

[0058] The present application provides the following experimental comparative examples to illustrate that the light control portion 212 a effectively blocks the non-direct sunlight rays outside the incident angle range 40.

[0059]

[0060] It should be noted that the experimental tests in the above table were completed under sunlight conditions with a light intensity of 100,000 LX.

[0061] In one embodiment, the thickness a of the light control layer 21 is in the range of 50 μm to 100 μm. The width b of the light-transmitting portion 211a is in the range of 100 μm to 300 μm. The width c of the light-controlling portion 212a is in the range of 5 μm to 50 μm. By reasonably configuring the thickness a of the light control layer 21, the width b of the light-transmitting portion 211a, and the width c of the light-controlling portion 212a, the light-regulating structural layer 20 can control sunlight at a specific angle under certain conditions so as to prevent it from passing through the sunroof glass 100, thereby protecting rear passengers.

[0062] Please continue reading Figure 3 In one embodiment, different specific incident angle values ​​can be obtained by setting the size ratio of the light-transmitting portion 211a and the light-controlling layer 21. For example, the specific incident angle is set to θ, the width of the light-transmitting portion 211a is set to b, and the thickness of the light-controlling layer 21 is set to a; wherein θ=arctga / b. That is, θ is specifically the angle between b and the sunlight perpendicular to the thickness direction of the skylight glass 100.

[0063] For example, when θ is 32°, a is 59.4μm and b is 100μm, that is, tan32°=59.4 / 100; when θ is 40°, a is 83.9μm and b is 100μm, that is, tan40°=83.9 / 100, and so on.

[0064] Please continue reading Figure 2In addition, based on any of the above embodiments, the light regulating structure layer 20 further includes a first protective layer 22 and a second protective layer 23, wherein the first protective layer 22 is stacked on one side of the light control layer 21 in the thickness direction, and the second protective layer 23 is stacked on the other side of the light control layer 21 in the thickness direction. Therefore, the first protective layer 22 and the second protective layer 23 also form an encapsulation protection for the light control layer 21, so as to prevent the light regulating structure layer 20 from being damaged when being assembled with the outer glass plate 10 and the inner glass plate 30.

[0065] For example, the first protective layer 22 and the second protective layer 23 may be made of, but not limited to, PET, PVC, etc.

[0066] Please continue reading Figure 1 In another embodiment, the skylight glass 100 further includes a first thermoplastic interlayer 40 and a second thermoplastic interlayer 50, wherein the first thermoplastic interlayer 40 is laminated between the outer glass plate 10 and the light regulating structure layer 20, and the second thermoplastic interlayer 50 is laminated between the inner glass plate 30 and the light regulating structure layer 20. The first thermoplastic interlayer 40 is used to bond and fix the outer glass plate 10 and the light regulating structure layer 20, and the second thermoplastic interlayer 50 is used to bond and fix the inner glass plate 30 and the light regulating structure layer 20, so that the outer glass plate 10, the light regulating structure layer 20 and the inner glass plate 30 are laminated and assembled to form the skylight glass 100.

[0067] It should be noted that the first thermoplastic interlayer 40 and the second thermoplastic interlayer 50 may be specifically thermoplastic films, which may be colored or transparent, with a visible light transmittance of 0% to 90%, such as 1%, 2%, 5%, 10%, 30%, 50%, 70%, 90%, etc. When used on the skylight glass 100 of the present application, the visible light transmittance is preferably 2% to 10% and the thickness is 0.38 mm to 1.52 mm.

[0068] Please continue reading Figure 1 In addition, based on any of the above embodiments, a first functional film layer 40a is provided in the middle of the side of the outer glass plate 10 facing the first thermoplastic interlayer 40, for example, the first functional layer 40a is a silver-based coating layer. First light blocking layers 40b are provided on both opposite side edges of the side of the outer glass plate 10 facing the first thermoplastic interlayer 40.

[0069] The first functional film layer 40a is distributed on most of the side of the outer glass plate 10 facing the first thermoplastic interlayer 40, and plays a good heat insulation role when facing the sun. The first edge blocking layer 40b arranged on both sides is mainly used to block the interior decoration of the roof edge.

[0070] Furthermore, a second functional film layer 50a is provided in the middle of the side of the inner glass plate 30 away from the second thermoplastic interlayer 50; for example, the second functional film layer is a TCO (transparent conductive oxide) film layer, and second edge blocking layers 50b are provided on the opposite side edges of the side of the inner glass plate 30 away from the second thermoplastic interlayer 50.

[0071] The second functional film layer 50a is arranged on most of the side of the inner glass plate 30 away from the second thermoplastic interlayer 50, which can further play a role in heat insulation and heat preservation, and helps to maintain the required temperature environment in the car and ensure riding comfort. The second edge blocking layer 50b arranged on both sides is mainly used to block the interior decoration on the edge of the roof.

[0072] For example, the first edge blocking layer 40b and the second edge blocking layer 50b may be made of, but not limited to, ceramic ink.

[0073] In addition to the above, the present application also provides a car, which can be any one of a pure electric car, an extended-range car, a pure fuel-powered car, etc.

[0074] The automobile includes a sunroof assembly, which includes a sunroof glass 100 as described in any of the above embodiments. In addition, the sunroof assembly also includes but is not limited to a sunroof guide rail, a sunroof motor and a glass bracket. Sunroof guide rail: responsible for guiding the glass panel to ensure that the sunroof works smoothly throughout the service life of the vehicle. Sunroof motor: composed of a motor body and a driver, which operates in an automatic controlled manner to avoid oscillation and loss of step when the load suddenly changes. Sunroof glass 100 (with a sealing strip): tempered glass is usually used, which forms uniform small particles without sharp corners after being broken, and is called safety glass. Glass bracket: a bracket for mounting the sunroof glass 100, with a sunroof hole formed on the body, and mounting bolts fixedly connected to the surrounding body frame. These components work together to enable the sunroof to be opened and closed smoothly, while improving the air circulation in the car, increasing the entry of fresh air, broadening the field of vision of the driver and passengers, and meeting the shooting needs of mobile photography and videography.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application.
