Abstract
Description
Technical Field
[0001] The invention relates to a device comprising a heating layer and also to a vehicle having such a device. Background Art
[0002] Vehicles have panel heaters in various locations. They are applied to opaque surfaces, such as the side trim panels. Summary of the invention
[0003] It is desirable to provide a device, in particular a device for a vehicle window pane, to improve the comfort of the vehicle interior, in particular to provide such a device on the roof, windshield, rear window and / or side windows.
[0004] According to one embodiment, a device for a vehicle has:
[0005] a first pane element having a first main surface and a second main surface, the second main surface being located opposite the first main surface in the stacking direction,
[0006] a second pane element having a third main surface and a fourth main surface, the fourth main surface being located opposite the third main surface in the stacking direction, the second pane element being coupled to the first pane element,
[0007] a third pane element having a fifth main surface and a sixth main surface, the sixth main surface being located opposite the fifth main surface in the stacking direction, a pane gap being arranged between the second pane element and the third pane element, the third pane element being thermally decoupled from the second pane element,
[0008] A heating layer coupled to the third pane element and configured to increase the temperature of the vehicle interior.
[0009] The areas of the first, second, third, fourth, fifth and sixth major surfaces are all greater than the areas of the transversely arranged side surfaces of the first, second and third pane elements. The first pane element extends straightly, and the extension range along the first and second major surfaces is significantly greater than the transverse extension range. The second pane element extends straightly, and the extension range along the third and fourth major surfaces is significantly greater than the transverse extension range. The third pane element extends straightly, and the extension range along the fifth and sixth major surfaces is significantly greater than its transverse extension range. The first and second pane elements are arranged in the stacking direction so that the third major surface and the second major surface are aligned with each other. In addition, the second and third pane elements are arranged in the stacking direction so that the fourth and fifth major surfaces are aligned with each other.
[0010] The first and second pane elements are coupled together and may also be collectively referred to as an outer pane of the vehicle.
[0011] The pane gap between the second and third pane elements firstly allows thermal decoupling between the second and third pane elements. When the device is used on a vehicle, the third pane element forms a pane element which is assigned to the interior of the vehicle and can be referred to as the inner pane of the vehicle. The inner pane can be a single pane or a laminated pane having at least two panes. The thermal decoupling offers advantages for heat protection in summer and winter. In summer, the inner pane is not heated to such an extent that it feels pleasantly cool. In winter, the inner pane maintains a higher temperature even when driving, which makes it feel more comfortable.
[0012] This is associated with more efficient cooling in summer or more efficient heating in winter, saving energy and therefore reducing the running costs of the vehicle.
[0013] In this case, thermal decoupling means that the heat exchange between the second and third pane elements is at least reduced. The mechanisms of heat exchange are as follows: conduction, convection and thermal radiation.
[0014] The heating layer is a transparent, electrically conductive layer. Since heat radiation essentially gives a pleasant feeling, the heating layer can also be operated with the same comfort at relatively low room temperatures. Due to the lower indoor air temperature, heat losses through enclosed spaces, such as through the body or glass elements, are also reduced. In winter, for example, and especially when driving, the window panes are constantly cooled from the outside by air currents. Through the combination of thermal decoupling and the heating layer applied to the third glass element, the outside environment is not heated at the same time, so that even more energy can be saved when the vehicle is in motion. As a result, the temperature regulation of the inner pane is very comfortable, which increases the comfort of the occupants.
[0015] On the other hand, in summer, due to the thermal decoupling, the inner pane is not heated as strongly and thus feels cooler. This arrangement avoids the glass being heated to over 80°C in direct sunlight and occasionally causing burns due to accidental contact, such as burns to the skin of the hands or head.
[0016] Alternatively, the heating layer can also be installed in the glass laminate or on the upper and / or lower side of the glass laminate. Furthermore, the heating layer can be used in sections instead of as a heating layer for the entire surface. In this case, such a sectioned heating layer is transparent and / or opaque.
[0017] According to at least one embodiment, the device has a conductive layer, such as a metal layer. Alternatively, the device has, for example, nanotubes, graphite and / or indium tin oxide (ITO) as the conductive layer. The conductive layer is applied to the fourth main surface of the second panel element. A grid structure or a line structure can also be used instead of a planar layer.
[0018] For example, the metal layer can be configured as a wavelength selective coating with low emissivity (low-E). The low-emissivity layer is as transparent as possible to the incident sunlight to obtain a high overall energy transmittance and not to shift the visible light spectrum. For example, silver, copper, gold or tin oxide layers can be used as materials for the low-emissivity layer. In order to improve the transmittance and durability of the low-emissivity layer, the silver coating can be embedded in the oxide layer. The low-emissivity layer can reduce the heat loss caused by thermal radiation, thereby saving more energy when the vehicle is driving. At the same time, an effective low-emissivity layer can also improve thermal management. The low-emissivity layer can reflect the energy of the heating layer in the direction of the inner window pane, in particular, ensuring that the energy is not dissipated through the outer window pane. Alternatively, the low-emissivity layer can also be applied to the fifth main surface. For example, if the low-emissivity layer is laid on the fifth main surface, then in winter, it can reduce the heat loss to the outside, and in summer, it can reduce the heat input to the inside. At the same time, it can also be used as a conductive layer and / or a heating layer.
[0019] According to at least one embodiment, the device has a shading assembly. The shading assembly is located between the first and third pane elements and can darken the interior of the vehicle. Alternatively, the shading assembly is arranged below the third pane element.
[0020] The shade assembly can block direct sunlight and thus reduce the heat inside the vehicle. This effect is further enhanced in combination with a thermally decoupled inner pane. Even if the first pane element and / or the second pane element is heated, the heat radiated into the vehicle interior is reduced.
[0021] According to at least one embodiment, the shielding assembly is arranged between the second and the third pane elements and comprises a switchable membrane.
[0022] The switchable film is for example formed of a suspended particle component (suspended particle device, SPD) and / or an electrochromic layer (EC) and / or a liquid crystal (LC) or polymer dispersed liquid crystal (PDLC), or comprises such materials.
[0023] Furthermore, the switchable membrane is also embedded in a layer made of, for example, polyvinyl butyral (PVB) and / or ethylene vinyl acetate (EVA) and / or thermoplastic polyolefin (TPO) and / or polyolefin (PO) and / or thermoplastic polyurethane (TPU) or comprising such materials.
[0024] Therefore, the switchable membrane has a convenient shielding function.
[0025] Furthermore, the electrodes of such a membrane can also form a heating layer.
[0026] Furthermore, for example, polyvinyl butyral (PVB) can strengthen the coupling between the first pane element and the second pane element. The two pane elements thus form an integral structure. From a physical point of view, the two pane elements thus become one pane, which contributes to the effect of forces during operation, for example during movement. Thus, the first and second pane elements can be prevented from shifting relative to each other.
[0027] According to one embodiment, the shading assembly is arranged between the second and the third pane elements and comprises a roller blind device.
[0028] Roller blinds can directly darken the interior of the vehicle and reduce heat input from the sun. This has the added benefit of improving energy efficiency.
[0029] According to one embodiment, the pane gaps are filled with an insulating gas.
[0030] Spacers can be used in the pane gaps to stabilize against external pressure. For example, so-called spacer strips can be used, which include a desiccant, a moisture barrier and spacers. The use of insulating gas in the pane gaps can effectively reduce heat losses due to conduction and convection. Insulating gas has lower heat losses than normal air. Insulating gas in the pane gaps also reduces noise, thereby increasing comfort in the vehicle interior.
[0031] According to one embodiment, the pane gaps are evacuated.
[0032] Since the pressure in the evacuated space is low, gaskets can be used in the pane gap to stabilize against external pressure. In non-evacuated pane gaps, the pressure in the pane gap increases due to sunlight exposure. The stress on the glass pane and the risk of damage to the glass pane increase with increasing pressure. Using an evacuated pane gap can largely prevent the pressure increase. An evacuated pane gap also reduces the conduction and convection losses of heat due to the absence of an air or gas layer. In addition, the vacuum in the pane gap reduces noise, which further increases the comfort level in the vehicle interior.
[0033] Another advantage of the pane gaps is that disturbing reflections on the inner panes can be reduced. Since thermal management is mainly achieved by thermal isolation between the panes, the low-e reflective layer on the inside can be omitted. This will ensure better driving safety and provide a more comfortable traffic environment for the occupants.
[0034] According to one embodiment, the heating layer is formed by film layer and / or evaporation.
[0035] For example, the heating layer can be integrated into a film made of or comprising polyvinyl butyral (PVB) and / or polyethylene terephthalate (PET). Polyvinyl butyral (PVB) is notable for its adhesive effect and high tear strength. This has the advantage that the heating layer can be used as an additional anti-splitting protection layer.
[0036] The heating layer can be applied by conventional methods. These methods include vacuum deposition methods such as physical evaporation, thermal evaporation, electron beam evaporation and other methods.
[0037] According to one embodiment, the heating layer is applied to the fifth and / or sixth main surface of the third pane element.
[0038] Using a heating layer on the sixth major surface can heat the side of the inner pane facing the interior of the vehicle more quickly, thereby improving comfort.
[0039] In addition, the use of a heating layer in the form of a film layer can also effectively protect the third pane element. Therefore, when the third glass element is damaged, the vehicle interior can also be protected.
[0040] By arranging the heating layer on the fifth main surface of the third pane element, the heating layer is encapsulated and better protected against external influences.
[0041] In case a vapor deposited and / or printed heating layer is used, the heating layer may also serve as a spacer for the pane gaps.
[0042] Furthermore, the heating layer prevents possible corrosion in the evacuated pane gaps.
[0043] According to one embodiment, the third pane element is a plate-shaped light guide element. The light guide element is coupled to the light source and is suitable for guiding light inputted from the light source and providing predetermined lighting for the interior of the vehicle.
[0044] By using the inter-panel gaps adjacent to the plate-shaped light guide as a medium, total internal reflection required for effective illumination is improved. The medium in the inter-panel gaps has a lower refractive index than air, thus allowing the light to make larger angles with the interface layer.
[0045] The greater the angle relative to the interface layer, the higher the light intensity, since the light within the light-guiding element is reflected more times within a predetermined distance.
[0046] According to at least one embodiment, a vehicle is provided, the vehicle having a device according to one of the embodiments described herein, at least one vehicle opening and a closing element. The closing element has the device described above and is configured to close the vehicle opening.
[0047] The device is, for example, a windshield. Alternatively or additionally, the device is, for example, a sunroof. Alternatively or additionally, the device is a side window. Alternatively or additionally, the device is a rear window.
[0048] The vehicle may be a motor vehicle, such as a car or a truck. Public transportation, such as a bus or a train, is also included. BRIEF DESCRIPTION OF THE DRAWINGS
[0049] An exemplary embodiment of the present disclosure is explained in more detail below with the aid of schematic diagrams, wherein:
[0050] Figure 1 shows a schematic diagram of a portion of a vehicle according to an exemplary embodiment;
[0051] Figures 2 to 7 are schematic diagrams of devices according to exemplary embodiments, respectively;
[0052] Elements having the same design and function are provided with the same reference symbols in the figures. DETAILED DESCRIPTION
[0053] In this description, terms such as "upper", "lower", "upper side", "lower side", "inner" and "outer", "front" and "rear" refer to the arrangements and orientations shown in the drawings and are conventional in a vehicle ready for operation.
[0054] Figure 1 A device 1 for a vehicle 100 is shown, which forms a closure element 102 in the vehicle 100 , which closure element is configured to close a vehicle opening 101 in the vehicle 100 .
[0055] The closing element 102 is formed, for example, as a cover 104 in the roof 103, which is configured to close a top opening 105 in the roof 103. The device 1 can form a part or a portion of the cover 104, for example a sunroof 110, or completely form a cover. The closing element 102 is configured, for example, as a glass cover. In addition, the device 1 can also form a part of a windshield 106, a rear window 107 or a side window 108, or alternatively completely form a windshield, a rear window or a side window.
[0056] Vehicle longitudinal direction 109 extends from rear window 107 to windshield 106 .
[0057] Figure 2An exemplary embodiment of a device 1 is shown in the form of a schematic side view. The device 1 initially has a first pane element 10 along a stacking direction 200. In the ready-to-operate state, the first pane element 10 faces outwards and is arranged away from the interior of the vehicle 100. The first pane element 10 has a first main surface 11 and an oppositely arranged second main surface 12. In the ready-to-operate state, the first main surface 11 faces outwards. In the ready-to-operate state, the second main surface 12 faces the interior of the vehicle 100. In particular, the second main surface 12 is arranged opposite to the first main surface 11 along the stacking direction 200. The device 1 has a second pane element 20. The second pane element 20 has a third main surface 21 and a fourth main surface 22. The third main surface 21 faces the first pane element 10. The fourth main surface 22 is arranged opposite to the third main surface 21 along the stacking direction 200. The first pane element 10 and the second pane element 20 are arranged in the stacking direction 200 such that the third main surface 21 and the second main surface 12 are aligned with each other.
[0058] The device 1 has a third pane element 30. The third pane element has a fifth main surface 31 and a sixth main surface 32. The fifth main surface 31 faces the second pane element 20. The sixth main surface 32 is arranged opposite to the fifth main surface 31 along the stacking direction 200. In the ready-to-operate state, the third pane element 20 faces the interior of the vehicle 100. Furthermore, the second pane element 20 and the third pane element 30 are arranged in the stacking direction 200 such that the fourth main surface 22 and the fifth main surface 31 are aligned with each other.
[0059] The six main surfaces 11, 12, 21, 22, 31, 32 are oriented in the same manner and are kept at a certain distance from each other. The six main surfaces 11, 12, 21, 22, 31, 32 are arranged in particular parallel to each other within a conventional tolerance range.
[0060] The first pane element 10, the second pane element 20 and the third pane element 30 are in particular transparent glass panes. The pane elements 10, 20 and 30 can also be tinted glass. Alternatively or additionally, polycarbonate and / or polymethyl methacrylate (PMMA) panels can also be used.
[0061] The first pane element 10 and the second pane element 20 are connected to each other via a plastic layer 50. The plastic layer 50 is, for example, a polyvinyl butyral (PVB) layer. The plastic layer 50 serves as a hot melt adhesive layer in order to connect the first pane element 10 and the second pane element 20 together. Thus, along the stacking direction 200, the first pane element 10 is arranged first, followed by the plastic layer 50 and then by the second pane element 20. A switchable film 60 is embedded in the plastic layer 50. The switchable film 60 is, for example, formed by a suspended particle component (suspended particle device, SPD) and / or a liquid crystal (LC) or a polymer dispersed liquid crystal (PDLC) or comprises such materials. Thus, the switchable film 60 constitutes a shielding component 60, which can conveniently darken the interior of the vehicle and / or change the light transmittance through the device 1, for example by higher light scattering.
[0062] The first pane element 10 and the second pane element 20 can also be collectively referred to as an outer pane. Thus, the first pane element 10 and the second pane element 20 form an integral pane without thermal decoupling. From a physical point of view, the two pane elements 10 and 20 are thus one pane, which has a certain effect on the forces acting, for example, during movement.
[0063] A metal layer 40 is applied to the fourth main surface 22 of the second pane element 20. The metal layer 40 is configured, for example, as a wavelength selective coating with low emissivity (low-E). The low-E layer is as transparent as possible. The low-E layer can reduce heat loss caused by thermal radiation.
[0064] For example, if a low-emissivity layer is laid on the fifth main surface 31, the heat loss to the outside can be reduced in winter, and the heat input to the inside can be reduced in summer. At the same time, it can also be used as a conductive layer and / or a heating layer.
[0065] The second pane element 20 is followed by a pane gap 90 and then by a third pane element 30 , which may also be referred to as an inner pane.
[0066] The window pane gap 90 is evacuated or filled with insulating gas or air. The window pane gap 90 filled with insulating gas or air can effectively reduce the conduction loss of heat through thermal decoupling. The heat loss of insulating gas is lower than that of ordinary air.
[0067] The evacuated pane gap 90 can further reduce conduction heat loss, because there is no air layer or gas layer to allow conduction heat exchange. In addition, the insulating gas and vacuum in the pane gap 90 can also reduce noise, thereby further improving the comfort of the vehicle interior.
[0068] Another advantage of the pane gap 90 is that disturbing reflections on the inner pane can be reduced. On the one hand, the distance between the inner pane and the metal layer 40 ensures that reflections are reduced. On the other hand, a suitable choice of the medium in the pane gap 90 can cause the incident light to be refracted and reflected favorably at the interface layer between the third pane element 30 and the pane gap 90. This ensures higher driving safety and provides a more comfortable traffic environment for the occupants.
[0069] In this example, the heating layer 70 is located on the sixth major surface 32 of the third pane element 30 and is coupled to the latter. The heating layer 70 can be configured as a film, or can be evaporated and / or printed. Applying the heating layer 70 on the sixth major surface 32 can heat the side of the inner pane facing the vehicle interior more quickly, thereby improving comfort.
[0070] The heating layer 70 also ensures that the temperature inside the vehicle is more comfortable because the radiant heat makes people feel comfortable.
[0071] Figure 3 Another exemplary embodiment of the device 1 is shown in a schematic side view. Figure 2 The arrangement shown in is substantially the same, except that a roller blind device 65 is used as the shielding component 65 instead of the switchable film 60 .
[0072] Figure 4 A schematic side view of another exemplary embodiment of the device 1 is shown. Figure 3 The arrangement shown in is substantially the same, except that a switchable membrane 60 and a roller blind device 65 are both used as shading components 60 , 65 .
[0073] Figure 5 A schematic side view of another exemplary embodiment of the device 1 is shown. Figure 2 The device shown in FIG. 1 is substantially the same, except that the heating layer 70 is applied to the fifth main surface 31. By arranging the heating layer 70 on the fifth main surface 31 of the third pane element 30, the heating layer 70 is encapsulated and can be better protected against external influences. The heating layer 70 is configured, for example, as a low-emissivity layer, which has the advantage that heat losses due to thermal radiation are reduced, and the heating layer 70 can be used for heating with low heat losses.
[0074] In the case of using vapor deposition and / or printing heating layer 70, heating layer 70 can also be used as a spacer of window pane gap 90, so that heating layer 70 can resist pressure from the outside. In addition, in the case of evacuated window pane gap 90, heating layer 70 can also prevent possible corrosion.
[0075] Figure 6 Another exemplary embodiment of the device 1 is shown in a schematic side view. Figure 2 The device shown in FIG. 1 is substantially the same as that shown in FIG. 2 , except that the third pane plate element 30 is used as a plate-shaped light guide element 35. For example, white glass is used as the light guide element 35. The light guide element 35 is coupled to the light source 80. The light guide element 35 can guide the light input by the light source 80 to Figure 6 Take single light 85 as an example. This ensures the predetermined lighting inside the vehicle.
[0076] The heating layer 70 may be applied to the fifth major surface 31 or the sixth major surface 32 of the third pane element 30 .
[0077] In another embodiment, the second pane element 20 serves as the light guide element 35 and is coupled to the light source 80 .
[0078] Figure 7 A schematic side view of another exemplary embodiment of the device 1 is shown. Figure 2 The arrangement shown in is substantially the same except that a fourth pane element 95 having a seventh major surface 96 and an eighth major surface 97 is used.
[0079] The seventh major surface 96 faces the third pane element 30. The eighth major surface 97 is arranged opposite to the seventh major surface 96 in the stacking direction 200. In a ready-to-operate state, the fourth pane element 95 faces the interior of the vehicle 100. Furthermore, the third pane element 30 and the fourth pane element 95 are arranged in the stacking direction 200 such that the sixth major surface 32 and the seventh major surface 96 are aligned with each other.
[0080] The seventh main surface 96 and the eighth main surface 97 are similarly oriented and are spaced apart from each other and from the other six main surfaces 11, 12, 21, 22, 31, 32. The eight main surfaces 11, 12, 21, 22, 31, 32, 96, 97 are arranged in particular parallel to each other within conventional tolerances.
[0081] In the present embodiment, the heating layer 70 is encapsulated by arranging the heating layer 70 between the third pane element 30 and the fourth pane element 95 .
[0082] Alternatively, laminated safety glass is used for daylighting. In this case, the third pane element 30 is colored glass, and the fourth pane element 95 is white glass, which serves as a light guide element 35. The heating layer 70 is located between the third pane element 30 and the fourth pane element 95. In addition, a low-emissivity layer and / or an infrared reflective layer are also applied in this exemplary embodiment in an appropriate manner.
[0083] Through the combination of the window pane gap 90 and the light guide element 35 , the lighting efficiency of the vehicle interior is synergistically improved.
[0084] For the sake of clarity, the size ratios of the various components are not consistent with the actual size ratios of the device 1 .
