[0001] This application relates to the field of multifunctional glass technology, and in particular to an ambient window and its control method, and a vehicle. Background Technology
[0002] Ambient windows are sunroofs, side windows, front and rear windows that integrate ambient lighting functions. They are currently mainly used in automobiles. When in use, ambient windows display luminous patterns, which can make the interior of the car more dazzling at night, helping to create an atmosphere and ambiance.
[0003] The patterns displayed in ambient windows in related technologies are usually fixed and unchanging, resulting in a rather monotonous effect. How to achieve richer pattern presentation effects to improve the user's visual experience is a problem worthy of research. Summary of the Invention

[0052] Ambient windows are sunroofs, side windows, front and rear windows that integrate ambient lighting functions. They are currently mainly used in automobiles. When in use, ambient windows display luminous patterns, which can make the interior of the car more dazzling at night, helping to create an atmosphere and ambiance.
[0053] The patterns displayed in ambient windows in related technologies are usually fixed and unchanging, resulting in a rather monotonous effect. How to achieve richer pattern presentation effects to improve the user's visual experience is a problem worthy of research.
[0054] Based on this, an embodiment of the first aspect of this application proposes an ambient window, which aims to obtain richer pattern presentation effects to improve the user's visual experience.
[0055] like Figure 1As shown, the ambient window 10 in this embodiment includes a first light-transmitting plate 100, a second light-transmitting plate 200, a first intermediate layer 300, a second intermediate layer 400, a pattern layer 500, and a light source 600. The pattern layer 500 is disposed between the first light-transmitting plate 100 and the second light-transmitting plate 200. The pattern layer 500 is connected to the first light-transmitting plate 100 via the first intermediate layer 300 and to the second light-transmitting plate 200 via the second intermediate layer 400. The pattern layer 500 includes a transparent substrate layer 510 and a plurality of reflective patterns 520 formed on the transparent substrate layer 510. At least two of the plurality of reflective patterns 520 are configured to reflect visible light in different wavelength ranges. The light source 600 provides visible light in different wavelength ranges to the pattern layer 500.
[0056] Specifically, both the first light-transmitting plate 100 and the second light-transmitting plate 200 are light-transmitting plate-shaped components. The materials of the first light-transmitting plate 100 and the second light-transmitting plate 200 can be tempered glass, ordinary glass, or plexiglass. The first intermediate layer 300 and the second intermediate layer 400 are film layers with adhesive properties.
[0057] In this embodiment, the ambient window 10 has a pattern layer 500 disposed between the first light-transmitting plate 100 and the second light-transmitting plate 200. The pattern layer 500 includes a transparent substrate layer 510 and a plurality of reflective patterns 520 formed on the transparent substrate layer 510, wherein at least two reflective patterns 520 are configured to reflect visible light of different wavelength ranges. When the ambient window 10 is working, the light source 600 can sequentially provide visible light of different wavelength ranges to the pattern layer 500, so that each reflective pattern 520 is lit up sequentially. When the light source 600 switches between different wavelength ranges of visible light at a relatively fast frequency, the user will observe a pattern with a dynamic changing effect. Based on this, if the reflective patterns 520 are slightly different in shape, the user can see the effect of playing an animation. Thus, a richer and more dazzling display effect can be achieved, thereby improving the user's visual experience.
[0058] In some embodiments, the number of reflective patterns 520 is 2 to 10. It is understood that at least 2 reflective patterns 520 are required to achieve a dynamically changing pattern. Furthermore, an excessive number of reflective patterns 520 can lead to a thicker pattern layer 500. Therefore, in this embodiment, the number of reflective patterns 520 is set to 2 to 10. This ensures a dynamically changing pattern while keeping the thickness of the pattern layer 500 within a reasonable range, preventing it from becoming excessively thick.
[0059] In some embodiments, please refer to Figures 2 to 7There are six reflective patterns 520. The first reflective pattern 520 is configured to reflect violet light with a wavelength of 400nm~430nm, the second reflective pattern 520 is configured to reflect blue light with a wavelength of 430nm~450nm, the third reflective pattern 520 is configured to reflect cyan light with a wavelength of 450nm~500nm, the fourth reflective pattern 520 is configured to reflect green light with a wavelength of 500nm~570nm, the fifth reflective pattern 520 is configured to reflect yellow light with a wavelength of 570nm~600nm, and the sixth reflective pattern 520 is configured to reflect orange light with a wavelength of 600nm~630nm.
[0060] In this embodiment, the light source 600 can be configured to emit violet light, blue light, cyan light, filtered light, yellow light, and orange light in sequence, so that the first to sixth reflective patterns 520 are lit sequentially, and when a new reflective pattern 520 is lit, the previous reflective pattern 520 will darken. As each reflective pattern 520 is lit in sequence, an animation effect is displayed.
[0061] For example, such as Figures 2 to 7 As shown, the first to sixth reflective patterns 520 are all shaped like a rooster. The position and shape of the rooster in the different reflective patterns 520 are slightly different. When the first to sixth reflective patterns 520 are lit in sequence, the rooster will present an animation effect, such as an animation of a rooster walking or an animation of a rooster catching insects.
[0062] In some embodiments, please refer to Figures 8 to 15 There are seven reflective patterns 520. The first reflective pattern 520 reflects violet light with a wavelength of 400nm to 430nm, the second reflective pattern 520 reflects blue light with a wavelength of 430nm to 450nm, the third reflective pattern 520 reflects cyan light with a wavelength of 450nm to 500nm, the fourth reflective pattern 520 reflects green light with a wavelength of 500nm to 570nm, the fifth reflective pattern 520 reflects yellow light with a wavelength of 570nm to 600nm, the sixth reflective pattern 520 reflects orange light with a wavelength of 600nm to 630nm, and the seventh reflective pattern 520 reflects red light with a wavelength of 630nm to 760nm.
[0063] In this embodiment, the light source 600 can be configured to emit violet light, blue light, cyan light, filtered light, yellow light, orange light, and red light sequentially, so that the first to seventh reflective patterns 520 are lit up in sequence, and when a new reflective pattern 520 is lit up, the previous reflective pattern 520 will darken. As each reflective pattern 520 is lit up in sequence, an animation effect is displayed.
[0064] For example, such as Figures 8 to 14 As shown, the first to seventh reflective patterns 520 are all shaped as closed rings, with the size of the rings gradually decreasing from the first to the seventh reflective pattern 520. When the first to the seventh reflective patterns 520 are lit up in sequence, the closed rings exhibit an animation effect of decreasing in size.
[0065] Of course, such as Figure 15 As shown, the light source 600 can also be configured to emit white light after emitting red light. Since the white light is a mixed light, it can illuminate all seven reflective patterns 520. At this time, all the closed rings are lit up, presenting a "tunnel" shape with a three-dimensional visual effect, making the display effect richer.
[0066] In other embodiments, visible light of the same color can be divided into multiple bands. For example, the 630nm-760nm band containing red light can be further divided into three bands: 630nm-670nm, 670nm-710nm, and 710nm-760nm. Correspondingly, three of the multiple reflective patterns 520 are configured to reflect red light in the 630nm-670nm band, reflect red light in the 670nm-710nm band, and reflect red light in the 710nm-760nm band, respectively. Thus, when the light source 600 sequentially provides red light in the 630nm-670nm, 670nm-710nm, and 710nm-760nm bands, the three reflective patterns 520 can be lit sequentially.
[0067] In some embodiments, multiple reflective patterns 520 are stacked along the thickness direction of the transparent substrate layer 510, with different reflective patterns 520 located on different layers. Placing different reflective patterns 520 on different layers ensures that the different reflective patterns 520 do not interfere with each other, which allows for more flexible design of the shape and content of the reflective patterns 520.
[0068] In some embodiments, the transparent substrate layer 510 includes a plurality of stacked sublayers 511, each sublayer 511 having a reflective pattern 520. This arrangement allows different reflective patterns 520 to be located on different layers.
[0069] In some embodiments, the reflective pattern 520 is composed of a photonic crystal structure. Photonic crystal structures with different structural parameters have a selective effect on visible light of different wavelengths. Therefore, by adjusting the structural parameters of the photonic crystal structure, the reflective pattern 520 composed of the corresponding photonic crystal structure can reflect visible light of a specific wavelength.
[0070] Specifically, photonic crystal structures can be fabricated using nanoimprint technology.
[0071] In some embodiments, the transparent substrate layer 510 is made of PET or PC material, which has good mechanical properties, high strength and fatigue resistance, and high transmittance. Thus, when the reflective patterns 520 are not illuminated, the ambient window 10 as a whole has high transmittance, allowing the user to better observe the external environment through the ambient window 10.
[0072] In some embodiments, the ambient window 10 further includes a light guide 700, and both the light guide 700 and the light source 600 are located on the side of the first light-transmitting plate 100 away from the second light-transmitting plate 200. The light guide 700 has an incident light surface and an exit light surface, with the exit light surface located on the side of the light guide 700 closer to the first light-transmitting plate 100, and the light source 600 disposed facing the incident light surface.
[0073] The light guide 700 allows as much light as possible from the light source 600 to enter the first light-transmitting plate 100 and be received by the pattern layer 500. This improves the energy utilization of the light source 600 and enhances the brightness of the reflective pattern 520.
[0074] Furthermore, the light source 600 may include multiple LEDs 610, arranged in pairs, with each pair of LEDs 610 located on opposite sides of the light guide 700. This arrangement helps to improve the coverage of the light source 600, allowing the light emitted by the light source 600 to illuminate various positions of the pattern layer 500 more evenly. This helps to avoid uneven brightness at different positions of the reflective pattern 520, thereby improving the brightness uniformity of the reflective pattern 520.
[0075] In some embodiments, the material of the first intermediate layer 300 is one or more of PVB, EVA, and PU. The first intermediate layer 300 can not only bond the pattern layer 500 to the first light-transmitting plate 100, but also strengthen the first light-transmitting plate 100, thereby improving the impact resistance of the first light-transmitting plate 100.
[0076] In some embodiments, the material of the second intermediate layer 400 is one or more of PVB, EVA, and PU. The second intermediate layer 400 can not only bond the pattern layer 500 to the second light-transmitting plate 200, but also strengthen the second light-transmitting plate 200, thereby improving the impact resistance of the second light-transmitting plate 200.
[0077] An embodiment of the second aspect of this application provides a control method for an ambient window 10, applied to the ambient window 10 in any of the above embodiments. The control method includes:
[0078] The light source 600 sequentially provides visible light in different wavelength ranges to the pattern layer 500, so that at least two of the multiple reflective patterns 520 are lit up in sequence.
[0079] The control method of the ambient window 10 in this embodiment allows each reflective pattern 520 in the pattern layer 500 to be illuminated sequentially. Therefore, if the reflective patterns 520 have slightly different shapes, the user can see the effect of playing an animation. This results in a richer and more vibrant display effect, thereby enhancing the user's visual experience.
[0080] An embodiment of the second aspect of this application provides a means of transportation that includes the ambient window 10 of any of the above embodiments. Exemplarily, the means of transportation may be a car, train, airplane, etc. The ambient window 10 may be a sunroof, side window, or rear window.
[0081] In the vehicle embodiment of this application, an ambient window 10 has a pattern layer 500 disposed between a first light-transmitting plate 100 and a second light-transmitting plate 200. The pattern layer 500 includes a transparent substrate layer 510 and a plurality of reflective patterns 520 formed on the transparent substrate layer 510, wherein at least two reflective patterns 520 are configured to reflect visible light of different wavelength ranges. When the ambient window 10 is in operation, a light source 600 can sequentially provide visible light of different wavelength ranges to the pattern layer 500, causing each reflective pattern 520 to be illuminated sequentially. When the light source 600 switches between different wavelength ranges of visible light at a relatively fast frequency, the user will observe a pattern with a dynamic changing effect. Based on this, if the reflective patterns 520 are slightly different in shape, the user can see the effect of playing an animation. Thus, a richer and more dazzling display effect can be achieved, thereby improving the user's visual experience.
[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
