Description

Technical Field

[0001] The invention relates to a glazing arrangement comprising layers with different pigment concentrations. The invention also relates to a vehicle having such a glazing arrangement. Background Art

[0002] Laminated glass in the automotive industry is equipped with actively switchable layers. These switchable layers are combined together by lamination and can assist in darkening the interior of the vehicle. The layers used can transmit light to different degrees depending on the transmittance. Summary of the invention

[0003] It is desirable to provide a glass arrangement for a vehicle that can darken the interior of the vehicle more efficiently, thereby improving comfort. It is also desirable to provide a vehicle having such a glass arrangement.

[0004] According to one embodiment, a glass arrangement for a vehicle comprises a first glass element having a first main face and a second main face opposite to the first main face in a stacking direction. The glass arrangement further comprises a second glass element having a third main face and a fourth main face opposite to the third main face in a stacking direction, the second glass element being coupled to the first glass element. The glass arrangement further comprises a switchable intermediate layer arranged between the first glass element and the second glass element in the stacking direction. The glass arrangement further comprises a first plastic layer having a first thickness and a first pigment concentration in the stacking direction, the first plastic layer being arranged between the first glass element and the intermediate layer; and a second plastic layer having a second thickness and a second pigment concentration in the stacking direction, the second plastic layer being arranged between the second glass element and the intermediate layer, wherein the first pigment concentration is higher than the second pigment concentration.

[0005] The first main surface, the second main surface, the third main surface and the fourth main surface each have a greater extension than the transversely oriented side surfaces of the first glass element and the second glass element. The first glass element extends in a sheet-like manner and has a significantly greater extension along the first main surface and the second main surface than in its transverse direction. The second glass element extends in a sheet-like manner and has a significantly greater extension along the third main surface and the fourth main surface than in its transverse direction. The first glass element and the second glass element are arranged in a stacking direction such that the third main surface and the second main surface are oriented relative to each other.

[0006] The stacking direction is defined as starting from the side of the glass arrangement structure located outside the vehicle and pointing to the side of the glass arrangement structure located inside the vehicle. For example, the stacking direction is from the first main surface to the fourth main surface. The area on the side of the glass arrangement structure located inside the vehicle is also referred to as the vehicle interior.

[0007] The first glass element can serve as outer glass and, when installed, for example, in the roof of a vehicle, form the outermost element adjoining the exterior. Alternatively, one or more elements can cover the first glass element from above, so that said element faces outwards relative to the second glass element or the switchable intermediate layer, but is not realized as the outermost element. Correspondingly, the second glass element, serving as inner glass, can, when installed in the roof of a vehicle, form the innermost element that jointly delimits the vehicle interior. Alternatively, one or more elements can cover the second glass element from below, so that said element faces the vehicle interior relative to the first glass element, but is not realized as the innermost element.

[0008] The plastic layer between the two glass elements serves as a hot melt adhesive layer that connects the first glass element and the second glass element to each other.

[0009] The switchable interlayer can be implemented as a passive or active switchable interlayer. Active switchable interlayers include, for example, electrochromic glass (EC), liquid crystal glass (LC), polymer dispersed liquid crystal glass (PDLC), and glass with suspended particle components (SPD). For example, thermochromic glass and photochromic glass are both passive switchable interlayers. Glass arrangements are not limited to glass plates, but also include, for example, plastic plates.

[0010] The switchable intermediate layer enables adjustment of the translucency of the intermediate layer and thus of the entire glazing arrangement.

[0011] Additional layers can be provided on the main surface, for example in order to improve the darkening effect or to achieve other functions, such as regulating the interior temperature or improving the visual appearance.

[0012] In accordance with at least one embodiment, a first thickness of the first plastic layer is less than a second thickness of the second plastic layer.

[0013] In accordance with at least one embodiment, the switchable intermediate layer is embodied as a switchable film of polymer dispersed liquid crystal or comprises such a material.

[0014] The switchable intermediate layer is for example an actively switchable film formed of a suspended particle composition (suspended particle device, SPD) and / or an electrochromic layer (EC) and / or a liquid crystal (LC) and / or a polymer dispersed liquid crystal (PDLC), or comprises such materials.

[0015] A glass arrangement with a switchable film, for example consisting of polymer dispersed liquid crystal (PDLC), is part of a smart glass system that requires power to switch on and off. In the on state, a low voltage is applied, the molecules are oriented so that light from the spectrum visible to the human eye (also called visible light) can pass directly through, and the glass becomes transparent to the human eye. In the off state, the power is cut off, the molecules are randomly scattered again, so that the path of light is interrupted, and the glass becomes blurry to the human eye accordingly. The path of ultraviolet rays with wavelengths in the range of 280 nm to 380 nm and infrared rays with wavelengths in the range of 700 nm to 1000 nm through the glass is also at least partially interrupted.

[0016] The transparency can be controlled via the applied voltage. This is possible because at lower voltages only a few of the liquid crystals are fully oriented in the electric field, so only a small portion of the light can pass through, while most of it is scattered. Furthermore, the transparency, especially in the on state, depends on the properties of the switchable interlayer.

[0017] In accordance with at least one embodiment, the first plastic layer and / or the second plastic layer is embodied as a polyvinyl butyral layer or comprises such a material.

[0018] The switchable intermediate layer is embedded, for example, in a plastic layer which, for example, consists of polyvinyl butyral (PVB) and / or ethylene vinyl acetate (EVA) and / or thermoplastic polyolefin (TPO) and / or polyolefin (PO) and / or thermoplastic polyurethane (TPU) or comprises such materials.

[0019] The polyvinyl butyral (PVB) can be in different colors. For example, a dark polyvinyl butyral (PVB) is used. For example, the dark PVB has a black or dark grey color. The dark PVB is required to adjust the transmittance of visible light through the glass arrangement to a defined level.

[0020] According to at least one embodiment, the glass arrangement has a visible light transmittance of 3% to 12%.

[0021] According to ISO13837:2021, in the open state, the visible light transmittance of the entire glass arrangement structure is in the numerical range of 3% to 12%. The lower limit of 3% and the upper limit of 12% are both included in the numerical range. According to ISO13837:2021, in the closed state, the visible light transmittance of the entire glass arrangement structure is in the numerical range of 0% to 10%. The lower limit of 0% and the upper limit of 10% are both included in the numerical range. Dark PVB is used below and above the PDLC layer, for example, which is white, so that a dark gray appearance of the glass arrangement structure can be achieved both from the inside and outside of the vehicle, thereby improving the appearance of the vehicle. In addition or alternatively, dark PVB can also be used for other switchable layers. For example, for switchable layers with suspended particle components and / or with electrochromic layers and / or with liquid crystals, in which cases the transmittance of visible light can be higher than in the case of using polymer dispersed liquid crystals.

[0022] In the case of a symmetrical glazing structure, in order to achieve a visible light transmittance of about 3% to 12% for the entire glazing structure, each plastic layer must respectively include a dark PVB with a visible light transmittance in the range of 20% to 40%. PVB layers with this level of transmittance have a lower UV resistance than PVB layers with a lower transmittance. Because the first thickness is relatively low, the pigment concentration in the thinner layer is relatively high. This enables a higher UV resistance.

[0023] To achieve better UV resistance, the glazing arrangement is asymmetrical, where the first plastic layer has a higher pigment concentration than the second plastic layer, and the two plastic layers have similar transmittance. "Similar" here means that the transmittance of the two plastic layers is the same except for tolerances and slight deviations. Reducing the thickness of the first plastic layer increases the pigment concentration, which improves UV resistance.

[0024] Therefore, compared with a symmetrically structured glass arrangement, this glass arrangement has the following advantages: when the transmittance of the entire glass arrangement is the same, the glass arrangement has a higher UV resistance. In particular, the first plastic layer has a higher UV resistance. The improvement of UV resistance is accompanied by a longer material life, and accordingly, the life of each layer will also be extended.

[0025] Furthermore, polyvinyl butyral (PVB), for example, can enhance the coupling between the first glass element and the second glass element. As a result, the two glass elements form an integral structure. Therefore, from a physical point of view, the two glass elements are one glass, which is relevant, for example, in the event of impact forces when movement occurs during operation. As a result, relative displacement of the first glass element and the second glass element can be prevented.

[0026] According to at least one embodiment, an infrared-reflecting coating is applied to the second main surface.

[0027] Thus, light radiation can pass through the first glass element and the underlying layers and elements, but heat radiation is reflected to the outside. The reflected heat thus reduces the heat input to the vehicle interior. Thus, a brightness corresponding to daylight is achieved in the vehicle interior, but the vehicle interior is warmed to a lesser extent by heat radiation from sunlight. The infrared-reflecting coating is made of, for example, silver or comprises such a material.

[0028] The first glass element is, for example, a translucent glass plate to allow the use of an infrared reflective coating 40 on the second main face 12 to reflect infrared radiation. Additionally or alternatively, the second glass element is also a translucent glass plate to obtain similar bending properties as the first glass element during production in the furnace. Additionally or alternatively, the glass element may be colored. Additionally or alternatively, polycarbonate and / or polymethyl methacrylate (PMMA) plates may be used.

[0029] According to at least one embodiment, a low-emissivity, wavelength-selective coating is applied on the fourth main face.

[0030] A low emissivity (low-E) wavelength selective coating, also referred to as a low-E layer, can be implemented, for example, as a metal oxide layer. The low-E layer reduces the total energy entering the interior of the vehicle by cutting the radiation of energy absorbed by dark PVB and / or glass. An exemplary material for the low-E layer is indium tin oxide (ITO). The material reflects infrared radiation, especially infrared radiation in the wavelength range greater than 1400 nanometers. In order to increase the transmittance and durability of the low-E layer, for example, a silver coating is embedded in the oxide layer. For example, in winter when the outdoor temperature is low, the low-E layer can reduce heat loss due to thermal radiation, thereby saving energy when the vehicle is running. For example, in summer when the outdoor temperature is high, the low emissivity of the absorbed energy of the low-E layer reduces the total transmitted solar energy (TTS) inside the vehicle.

[0031] According to at least one embodiment, the first plastic layer has a first thickness of 0.25 mm to 0.55 mm.

[0032] According to at least one embodiment, the second thickness of the second plastic layer is 0.5 mm to 0.85 mm.

[0033] The first thickness of the first plastic layer is less than the second thickness of the second plastic layer. The first thickness is, for example, 0.25 mm to 0.55 mm. The numerical range of the first thickness includes a lower limit of 0.25 mm and an upper limit of 0.55 mm. The second thickness is, for example, 0.5 mm to 0.85 mm. The numerical range of the second thickness includes a lower limit of 0.5 mm and an upper limit of 0.85 mm.

[0034] According to one embodiment, the second glass element is a sheet-shaped light guide element, which is coupled to the light source and configured to guide the light fed from the light source and provide it for specific lighting inside the vehicle.

[0035] Due to the greater thickness of the second plastic layer, the second plastic layer has a lower pigment concentration than the first plastic layer at the same transmittance. This results in a higher light intensity, since the light is absorbed less by the adjacent layers within the light guide than by a medium with a higher pigment concentration. This enables more efficient lighting.

[0036] According to another aspect, a vehicle is disclosed. The vehicle has a vehicle opening and a glass arrangement structure according to one of the above-mentioned embodiments fixed in the vehicle opening. The vehicle substantially achieves the above-mentioned advantages and functions.

[0037] The vehicle is, for example, a motor vehicle, such as a passenger car or a truck, and also includes public transportation, such as a bus or a train.

[0038] The glass arrangement is, for example, a roof with a skylight. Additionally or alternatively, the glass arrangement is, for example, a front window. Additionally or alternatively, the glass arrangement is, for example, a rear window. Additionally or alternatively, the glass arrangement is, for example, a side window.

[0039] Exemplary embodiments of the present disclosure are explained in more detail below with reference to schematic diagrams.

[0042] Figure 3 A schematic diagram of another exemplary embodiment of a glass arrangement is shown.

[0045] Elements having the same structure and function are provided with the same reference numerals in all the drawings. DETAILED DESCRIPTION

[0046] In this specification, terms such as "top", "bottom", "top side", "bottom side", "inside" and "outside", "front" and "rear" refer to the general orientation and direction of the motor vehicle as shown in the figures and ready for operation.

[0047] Figure 1 Shown is a glass arrangement 1 for a vehicle 100, which is implemented, for example, as a cover 102 in a roof 101, which is implemented to close a vehicle opening 103 in the roof 101. The glass arrangement 1 can form a part or portion of the cover 102, or alternatively can be fully implemented. The glass arrangement 1 is configured, for example, as a glass cover or a cover made of plastic or other common materials. In addition, the glass arrangement 1 can, for example, form a part or portion of a front window 104, a rear window 105 or a side window 106, or alternatively can be fully implemented. The vehicle length direction L2 extends from the rear window 105 to the front window 104.

[0048] Figure 2 A schematic cross-sectional view of an exemplary embodiment of a glass arrangement 1 is shown. Along the stacking direction L1, the glass arrangement 1 first comprises a first glass element 10. In the operationally ready state, the first glass element 10 is arranged to face outward and away from the interior of the vehicle 100. The first glass element 10 has a first main face 11 and an opposite second main face 12. In the operationally ready state, the first main face 11 faces outward. In the operationally ready state, the second main face 12 faces the interior of the vehicle 100. In particular, the second main face 12 is arranged opposite to the first main face 11 along the stacking direction L1. The glass arrangement 1 comprises a second glass element 20. The second glass element 20 has a third main face 21 and a fourth main face 22. The third main face 21 faces the first glass element 10. The fourth main face 22 is arranged opposite to the third main face 21 along the stacking direction L1. Corresponding to the stacking direction L1, the first glass element 10 and the second glass element 20 are arranged so that the third main face 21 and the second main face 12 are oriented to each other.

[0049] The four main surfaces 11, 12, 21, 22 are arranged in the same direction and are spaced apart from each other. In a conventional tolerance range, the four main surfaces 11, 12, 21, 22 are arranged parallel to each other.

[0050] The first glass element 10 and the second glass element 20 are in particular translucent glass plates. Additionally or alternatively, the glass elements 10, 20 may be colored. Additionally or alternatively, polycarbonate and / or polymethyl methacrylate (PMMA) plates may be used.

[0051] Arranged along the stacking direction L1 are first the first glass element 10, then the first plastic layer 70, then the switchable intermediate layer 50, and then the second plastic layer 75. Arranged subsequently along the stacking direction L1 is the second glass element 20. The first glass element 10 and the second glass element 20 are connected to each other by a first plastic layer 70 having a first thickness 71 and a first pigment concentration 72 and a second plastic layer 75 having a second thickness 76 and a second pigment concentration 77. The first plastic layer 70 and / or the second plastic layer 75 are, for example, implemented as layers made of polyvinyl butyral (PVB) or include such a material. The two plastic layers 70, 75 serve as hot melt adhesive layers for connecting the first glass element 10 and the second glass element 20 to each other. A frame 78 is arranged around the switchable intermediate layer 50. The frame 78 is located between the first glass element 10 and the second glass element 20 along the stacking direction L1. The size of the switchable intermediate layer 50 is smaller than the size of the two glass elements 10, 20. Therefore, the switchable intermediate layer 50 does not reach the edges of the two glass elements 10, 20. In order to avoid height differences along the glass arrangement 1 at the edges of the glass elements 10, 20, a frame 78 is provided. The frame 78 can include the same material as the two plastic layers 70, 75. The frame 78 is formed, for example, by polyvinyl butyral (PVB) and / or ethylene-vinyl acetate (EVA) and / or thermoplastic polyolefin (TPO) and / or polyolefin (PO) and / or thermoplastic polyurethane (TPU) or includes such material. The optical properties of the frame 78 play a secondary role, because the frame 78 is hidden by the dark color at the edges of the glass elements 10, 20 and is therefore not visible. The first thickness 71 of the first plastic layer 70 is less than the second thickness 76 of the second plastic layer 75. The first thickness 71 is, for example, 0.25 mm to 0.55 mm. The value range of the first thickness 71 includes a lower limit of 0.25 mm and an upper limit of 0.55 mm. The second thickness 76 is, for example, a value of 0.5 mm to 0.85 mm. The value range of the second thickness 76 includes a lower limit of 0.5 mm and an upper limit of 0.85 mm. The polyvinyl butyral (PVB) can be in different colors. To achieve similar translucency, the first pigment concentration 72 in the thinner first plastic layer 70 is higher than the second pigment concentration 77 in the thicker second plastic layer 75. Due to the lower first thickness 76 and the higher pigment concentration in the first plastic layer 70, the first plastic layer 70 has a higher UV resistance, which results in a longer service life of the glass arrangement 1. Figure 2 In the embodiment of the present invention, two plastic layers 70, 75, which consist of, for example, dark-colored polyvinyl butyral, are arranged above and below a switchable intermediate layer 50, which comprises, for example, a white PDLC layer. In this way, a dark-gray appearance of the entire glass arrangement 1 can be achieved both from the vehicle interior and from the vehicle 100 exterior, thereby improving the visual appearance.

[0052] The switchable intermediate layer 50 is embedded between the two plastic layers 70, 75. The switchable intermediate layer 50 is formed, for example, by a suspended particle composition (suspended particle device SPD) and / or a liquid crystal (LC) and / or a polymer dispersed liquid crystal (PDLC), or comprises such a material. Thus, the switchable intermediate layer 50 constitutes a shading device 50, which is able to darken the vehicle interior in a comfortable manner and / or to change the transmission of light through the glass arrangement 1, for example by greater light scattering.

[0053] Figure 3 FIG. 2 shows a schematic cross-sectional view of another exemplary embodiment of a glass arrangement 1. Figure 2 The same as in the embodiment of the present invention, except that an infrared reflective coating 40 is applied to the second main face 12. Therefore, light radiation can pass through the first glass element 10 and the underlying layers and elements. Thermal radiation is reflected by the infrared reflective coating 40 and reflected to the outside. Therefore, the reflected heat reduces the heat input to the interior of the vehicle.

[0054] The first glass element 10 is, for example, a translucent glass plate to allow the use of an infrared reflective coating 40 on the second main face 12 to reflect infrared radiation. Additionally or alternatively, the second glass element 20 is also a translucent glass plate to produce similar bending properties as the first glass element 10 during production in the furnace. Additionally or alternatively, the glass elements 10, 20 may be colored. Additionally or alternatively, polycarbonate and / or polymethyl methacrylate (PMMA) plates may be used.

[0055] Figure 4 FIG. 2 shows a schematic cross-sectional view of another exemplary embodiment of a glass arrangement 1. Figure 3 , except that a low emissivity (low-E) wavelength selective coating 60 is applied on the fourth main surface 22. The low emissivity wavelength selective coating 60, also referred to as a low-E layer, is, for example, implemented as a metal oxide layer or includes such a material. For example, an indium tin oxide layer is used as a material for the low-E layer 60. Additionally or alternatively, the low-E layer 60 can be applied to the infrared reflective coating 40. Only the low-E layer 60 can be applied to the glass arrangement 1 without applying the infrared reflective coating 40.

[0056] Figure 5 FIG. 2 shows a schematic cross-sectional view of another exemplary embodiment of a glass arrangement 1. Figure 4 The light guide element 25 is the same as in the embodiment except that the second glass element 20 is used as a sheet-like light guide element 25. The light guide element 25 used is, for example, a translucent glass plate, such as white glass or transparent glass. Additionally or alternatively, a translucent plastic plate may be used. The light guide element 25 is coupled to the light source 80. The light guide element 25 can conduct the light fed from the light source 80. Figure 5In FIG. 8 , the light is schematically represented based on a single light ray 85 represented by a dashed line. This ensures a specific illumination of the vehicle interior.

[0057] The use of a second plastic layer 75 adjacent to the second glass element 20 allows for a higher light intensity because light rays 85 within the light guide element 25 are absorbed to a lesser extent by the adjacent second plastic layer 75 than by a medium with a higher pigment concentration. The combination of the second plastic layer 75 and the light guide element 25 synergistically improves the efficiency of the vehicle interior lighting.

[0058] Additionally or alternatively, the light guide element 25 and the light source 80 can be applied to the infrared reflective coating 40 and / or the metal oxide layer 50. Any combination of the infrared reflective coating 40, the metal oxide layer 60, and the light guide element 25 and the light source 80 is possible. The glass arrangement 1 can also include only the light guide element 25 and the light source 80, without including the infrared reflective coating 40 and the metal oxide layer 60.

[0059] For the sake of clarity, the proportions of the individual components do not correspond to the actual proportions of the glazing arrangement 1 .
