Abstract
Description
Technical Field
[0001] This application relates to the technical field of vehicle window glass, and particularly to a dimming assembly and a vehicle.
Background Art
[0002] Vehicle windows are one of the important components of automobiles. To ensure the driving safety of automobiles, it is required that vehicle window glass has safety performance parameters such as high strength and rigidity. In addition, since the weight of vehicle windows usually accounts for 3% - 10% of the total vehicle body weight, by reducing the weight of vehicle windows, the weight of the entire vehicle body can be effectively reduced, and as a result, the fuel consumption of automobiles can be reduced.
[0003] Vehicle window glass is usually designed as laminated glass, including two or more inorganic glass plates and one or more functional film layers provided therebetween. Laminated glass has excellent safety and sound insulation properties, and when applied to vehicle windows of automobiles, it can be used as front glass, rear glass, side window glass, sunroof glass, etc. In related technologies, when the functional film layer is set as a dimming functional layer, the dimming functional layer is connected to two glass substrates through adhesive layers respectively, and the adhesive layer is composed of a material with the same transmittance, a non-intermediate color material, and an adhesive layer material with different transmittances.
[0004] To darken the light transmission effect of vehicle window glass, usually, a two-layer dye liquid crystal LC dimming film layer is adopted, and the interaction of the two-layer dye liquid crystal LC dimming film layer realizes the effect of the dark state. However, in this case, the thickness of the vehicle window glass becomes relatively thick and the cost also increases. Of course, the effect of the dark state of the vehicle window glass can also be realized by a thick single-layer dye liquid crystal LC dimming film layer, that is, by adding more dye liquid crystals or increasing the thickness of the dye liquid crystal, and increasing the thickness of the dye liquid crystal LC dimming film layer can also realize a relative dark state, but defects such as dye precipitation, color unevenness, and non-uniformity are likely to occur.

Modes for Carrying Out the Invention
[0028] To make the above objects, features, and advantages of the present application clearer and easier to understand, the specific embodiments of the present application will be described in detail with reference to the accompanying drawings. In the following description, many specific details are described in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.
[0029] Refer to one of Figures 1 to 5. Figures 1 to 5 show schematic diagrams of the configurations of several different embodiments of the present invention. The dimming assembly provided in one embodiment of the present invention includes a first substrate layer 10, a dimming functional layer 20, and a polarizing film layer 30. The dimming functional layer 20 is connected to the first substrate layer 10. The polarizing film layer 30 is connected to the dimming functional layer 20 and is made of a transmissive polarizing material.
[0030] In the photochromic assembly described above, the polarizing film layer 30 is composed of a transmissive polarizing material and is bonded to the photochromic functional layer 20. Numerous tests and studies have confirmed that the photochromic assembly exhibits a dark state effect when light rays pass sequentially through the polarizing film layer 30 and the photochromic functional layer 20, or when light rays pass sequentially through the photochromic functional layer 20 and the polarizing film layer 30. Compared to related technologies that achieve a dark state effect through the interaction of two layers of photochromic functional layer 20, or through a thick photochromic functional layer 20, the polarizing film layer 30 in this embodiment has a relatively smaller thickness and lower material costs. When used in combination with the photochromic functional layer 20, it enables a reduction in the thickness, cost, and weight of the photochromic assembly. Furthermore, because the dye content doped into the photochromic functional layer 20 is low, precipitation due to high concentrations of dye can be avoided, improving the stability of the photochromic assembly.
[0031] In one embodiment, the visible light transmittance of the dimming functional layer 20 is ≥20%. Thus, the transmittance of the dimming film (LC) can be adjusted by adjusting the doped dye concentration in the dye-doped liquid crystal composition, or by increasing the thickness of the functional layer material (dye liquid crystal) in the same dye liquid crystal composition. Therefore, low transmittance not only means high costs, but also presents greater technical challenges in subsequent processing and experimentation.
[0032] Based on the content of the doped dye, the thickness of the photochromic functional layer 20, and the material cost, the visible light transmittance of the photochromic functional layer 20 is specifically set to, for example, 25% to 65%. This ensures that the content of the doped dye is not excessive, the thickness of the photochromic functional layer 20 is not excessive, and the material cost is appropriately suppressed.
[0033] Specifically, the visible light transmittance of the dimming functional layer 20 may be 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, etc., but is not limited to these.
[0034] In one embodiment, the visible light transmittance of the polarizing film layer 30 is ≥20%. Thus, the transmittance of the polarizing film layer 30 can be adjusted by adjusting the dye concentration during the manufacturing process, resulting in different transmittances. Lower transmittance means a higher dye concentration or a thicker material. If the transmittance of the polarizing film layer 30 is 20%, when used in combination with a photochromic functional layer 20 that has a dark state transmittance of 20%, a low dark state transmittance, for example, about 0.5%, can be obtained.
[0035] In one embodiment, the visible light transmittance of the polarizing film layer 30 is 20% to 40%. When the transmittance of the polarizing film layer 30 is 20% to 40%, and it is used in combination with a photochromic functional layer 20 having a dark state transmittance of 20%, a low dark state transmittance (0% to 1%), for example, a transmittance of about 0.5% to 0.8%, can be obtained. This can satisfy the demands of many users for low-transmittance photochromic products. Furthermore, when the polarizing film layer 30 having a visible light transmittance of 40% is used in combination with a photochromic functional layer 20 having a dark state transmittance of 60%, a relatively high dark state transmittance (25% to 40%) can be obtained, which can satisfy the building requirements for photochromic products with high dark state transmittance.
[0036] Specifically, the visible light transmittance of the polarizing film layer 30 may be 20%, 23%, 28%, 30%, 33%, 36%, 40%, etc., but is not limited to these.
[0037] In one embodiment, the dimming functional layer 20 includes one or more combinations of LC film, PDLC film, GHLC film, PNLC film, PSLC film, and PILC film.
[0038] In one embodiment, the dimming functional layer 20 includes, but is not limited to, one or more combinations of LC (dye liquid crystal) film, PDLC (polymer dispersed liquid crystal) film, GHLC (guest-host liquid crystal), PNLC (polymer network liquid crystal) functional element, PSLC (polymer stabilized liquid crystal) film, PILC (pixel-separated liquid crystal) film, etc.
[0039] In one embodiment, the initial arrangement state of the liquid crystals in the dimming functional layer 20 is either P-polarized or S-polarized. When the initial arrangement state of the liquid crystals in the dimming functional layer 20 is P-polarized, the polarizing film layer 30 is an S-polarizing film. When the initial arrangement state of the liquid crystals in the dimming functional layer 20 is S-polarized, the polarizing film layer 30 is a P-polarizing film. Thus, as a result of numerous tests and studies, it has been confirmed that when light rays pass sequentially through the polarizing film layer 30 and the dimming functional layer 20, or when light rays pass sequentially through the dimming functional layer 20 and the polarizing film layer 30, the dimming assembly exhibits a dark state effect.
[0040] Refer to any of Figures 1 to 5. In one embodiment, the dimming assembly further includes a filler layer 40 located in the same layer as the dimming functional layer 20 and positioned along the edge of the dimming functional layer 20. In this way, the flatness and stability of the configuration combining the dimming functional layer 20 and the other layers can be ensured.
[0041] In one embodiment, the thickness of the filling layer 40 is the same as the thickness of the dimming functional layer 20. In this way, the flatness and stability of the configuration combining the dimming functional layer 20 with other layers can be guaranteed.
[0042] In one embodiment, the filling layer 40 is composed of PVB material, EVA material, SGP material, or TPU material, but is not limited to these materials.
[0043] Refer to Figures 1 and 2. In one embodiment, the dimming assembly further includes a second substrate layer 50. The first substrate layer 10 and the second substrate layer 50 are connected to opposite sides of the dimming functional layer 20, respectively. The dimming assembly further includes a first adhesive layer 61 connected between the first substrate layer 10 and the dimming functional layer 20, and a second adhesive layer 62 connected between the second substrate layer 50 and the dimming functional layer 20. The polarizing film layer 30 is connected (as shown in Figure 1) between the second substrate layer 50 and the second adhesive layer 62, or (as shown in Figure 2) on the side of the second substrate layer 50 opposite to the first substrate layer 10. In this way, the first substrate layer 10, the first adhesive layer 61, the dimming functional layer 20, the second adhesive layer 62, the second substrate layer 50, and the polarizing film layer 30 are combined and firmly connected. Furthermore, since the first substrate layer 10 and the second substrate layer 50 are usually made of rigid material, the rigidity of the dimming assembly is sufficiently high and it is not easily damaged. In addition, to reduce damage caused by compression during the assembly process of the dimming functional layer 20, the dimming functional layer 20 is specifically made of, for example, a rigid sheet material, although of course, flexible sheet materials or composite sheet materials can be selected according to actual requirements.
[0044] Refer to Figures 3 to 5. Of course, in some optional configurations, the second substrate layer 50 may be omitted, that is, only the first substrate layer 10 may be used as the carrier. In this way, the pressing force applied to the dimming functional layer 20 during the process of pressing and assembling the dimming assembly becomes almost negligible, and it is possible to use not only a dimming functional layer 20 made of a rigid material but also a dimming functional layer 20 made of a flexible material. A dimming assembly assembled by pressing and assembling a dimming functional layer 20 made of a flexible material has an excellent appearance, and the occurrence of defects such as unevenness and inconsistency is avoided or reduced.
[0045] Refer to Figures 3 to 5. In one embodiment, if the second substrate layer 50 is omitted, the photochromic assembly further includes a scratch-resistant coating layer and / or a shatterproof coating layer connected to the polarizing film layer 30. In this way, a composite functional layer is formed by combining the polarizing film layer 30 and the scratch-resistant coating layer and / or shatterproof coating layer, enabling the realization of effects such as polarization, scratch resistance, and shatter prevention, and diversifying the functions of the product. Furthermore, the composite functional layer has higher rigidity than the polarizing film layer 30 and can perform the role of the second substrate layer 50, making it less susceptible to damage and extending its lifespan. Also, if the second substrate layer 50 is omitted, the thickness of the photochromic assembly can be reduced to some extent.
[0046] In one embodiment, the scratch-resistant coating layer is connected to the polarizing film layer 30 by a processing method such as spray coating or adhesive application, and a composite functional layer is formed in combination with the polarizing film layer 30, but the processing method is not limited to the above.
[0047] In one embodiment, the anti-scattering film layer is connected to the polarizing film layer 30 by a processing method such as spray coating or adhesive application, and a composite functional layer is formed in combination with the polarizing film layer 30, but the processing method is not limited to the above.
[0048] In some optional configurations, if the second substrate layer 50 is omitted, the polarizing film layer 30 can increase its rigidity by increasing its thickness and thus perform the role of the second substrate layer 50, making the dimming assembly less susceptible to damage and extending its lifespan.
[0049] Refer to Figures 3 to 5. In one embodiment, the dimming assembly further includes a first adhesive layer 61 connected between the first substrate layer 10 and the dimming functional layer 20, and a second adhesive layer 62 connected between the polarizing film layer 30 and the dimming functional layer 20. In this way, the first substrate layer 10, the first adhesive layer 61, the dimming functional layer 20, the second adhesive layer 62, and the polarizing film layer 30 are combined and firmly connected.
[0050] Refer to Figures 4 and 5. In one embodiment, the dimming assembly further includes a thin-film switch layer 70. The thin-film switch layer 70 is connected to one side of the polarizing film layer 30. When the thin-film switch layer 70 is integrated in this way, it does not affect the appearance of the product and can also make the product's performance more intelligent.
[0051] Selectively, the thin-film switch layer 70 includes, but is not limited to, a capacitive touch film. The thin-film switch layer 70 is electrically connected to a dimming controller and controls the dimming controller according to a defined touch pattern. The dimming controller can realize the dimming function by controlling the distribution state of the dye liquid crystal on the dimming function layer 20 accordingly.
[0052] Refer to Figures 4 and 5. In one embodiment, the dimming assembly further includes a third adhesive layer 63 located between the thin film switch layer 70 and the polarizing film layer 30. The thin film switch layer 70 is connected to the polarizing film layer 30 via the third adhesive layer 63. In this way, the third adhesive layer 63 enables a strong connection between the thin film switch layer 70 and the polarizing film layer 30. When the thin film switch layer 70 is located on the side of the polarizing film layer 30 facing the dimming function layer 20, the second adhesive layer 62 and the polarizing film layer 30 are indirectly connected, and when both the thin film switch layer 70 and the third adhesive layer 63 are located between the second adhesive layer 62 and the polarizing film layer 30, the thin film switch layer 70 is also connected to the second adhesive layer 62.
[0053] In one embodiment, the first adhesive layer 61 is composed of a PVB material, an EVA material, a TPU material, or an SGP material, but is not limited to these materials.
[0054] In one embodiment, the first adhesive layer 61 is composed of a PVB material, EVA material, TPU material, or SGP material having high UV blocking properties, and the UV cut wavelength is ≥390nm. Thus, using SPD dimming as an example, comparing the UV degradation results of the first adhesive layer 61 with a UV cut wavelength of ≥390nm and a normal PVB with a UV cut wavelength of 380nm in equivalent combinations, it was confirmed that after 5000 hours, the degradation of the transmittance of the SPD film in the case with a UV cut wavelength of ≥390nm was approximately 13% less compared to the case with a UV cut wavelength of 380nm.
[0055] In one embodiment, the UV-cut wavelength of the first adhesive layer 61 is 400 nm. Thus, using SPD dimming as an example, comparing the UV degradation results of the first adhesive layer 61 with a UV-cut wavelength of ≥390 nm and a normal PVB with a UV-cut wavelength of 380 nm in equivalent combinations, it was confirmed that after approximately 5000 hours, the degradation of the transmittance of the SPD film in the case with a UV-cut wavelength of 400 nm was approximately 15% less compared to the case with a UV-cut wavelength of 380 nm.
[0056] In one embodiment, the first adhesive layer is composed of a transition material such as a transition PVB material, a transition EVA material, a transition TPU material, or a transition SGP material, but is not limited to these materials. In this way, different luminescence effects can be achieved in different regions, and specifically, for example, gradient luminescence can be demonstrated.
[0057] In one embodiment, the method for selecting the materials for the second adhesive layer 62 and the third adhesive layer 63 is similar to that for the first adhesive layer 61, so a detailed explanation is omitted here.
[0058] In one embodiment, the first substrate layer 10 is composed of glass and PC material, but is not limited to these materials.
[0059] In one embodiment, the second substrate layer 50 is composed of glass and PC material, but is not limited to these materials.
[0060] Furthermore, when the first substrate layer 10 faces outwards from the vehicle body, that is, when it faces the surface that is directly exposed to sunlight, the second substrate layer 50 faces inwards from the vehicle body. Conversely, when the second substrate layer 50 faces outwards from the vehicle body, that is, when it faces the surface that is directly exposed to sunlight, the first substrate layer 10 faces inwards from the vehicle body.
[0061] Refer to one of Figures 1 to 5. In one embodiment, a vehicle is provided. The vehicle includes, but is not limited to, automobiles, buses, passenger cars, route buses, long-distance buses, trucks, jeeps, trains, high-speed rail, etc. The vehicle comprises a dimming assembly as in one of the embodiments described above. The dimming assembly includes, but is not limited to, a windshield, side windows, rear windows, and sunroof glass, etc.
[0062] In the vehicle described above, the polarizing film layer 30 is composed of a transmissive polarizing material and is bonded to the photochromic functional layer 20. Numerous tests and studies have confirmed that when light rays pass sequentially through the polarizing film layer 30 and the photochromic functional layer 20, or sequentially through the photochromic functional layer 20 and the polarizing film layer 30, the photochromic assembly exhibits a dark state effect. Compared to related technologies that achieve a dark state effect through the interaction of two layers of photochromic functional layer 20, or through a thick photochromic functional layer 20, the polarizing film layer 30 in this embodiment has a relatively smaller thickness and lower material costs. When used in combination with the photochromic functional layer 20, it enables a reduction in the thickness, cost, and weight of the photochromic assembly. Furthermore, because the dye content doped into the photochromic functional layer 20 is low, dye precipitation can be avoided.
