Description

Technical Field

[0001] The present invention relates to a vehicle window panel having the features of the preamble of claim 1. Background Technology

[0002] Such a vehicle window panel is known from document WO 2021 / 198262 A1 and is constructed as a cover element of a fixed roof element or roof opening system, by means of which the roof opening can be selectively closed or opened. The vehicle window panel includes a window panel body assembly having a composite structure and including a light guide layer formed on the inner side of the window panel body assembly, and strip-shaped light-coupled input elements for light are attached to the light guide layer, the light-coupled input elements being arranged on mutually opposing edge regions of the window panel body assembly. The light-coupled input elements are part of an illumination device including a light source, the light of which can be coupled into the light guide layer of the window panel body assembly through the light-coupled input elements. The coupled light can then be emitted from the light guide layer towards the vehicle interior space via corresponding coupling output elements. As previously described, light is coupled into the light guide layer on mutually opposing edge regions of the window panel body assembly. This requires a large number of light sources, which are also arranged along the relevant edges of the window panel body assembly. In addition, wiring is required for the light sources arranged on both sides, which involves not only manufacturing technology costs but also corresponding material and cost costs. Summary of the Invention

[0003] The objective of this invention is to provide a vehicle window panel constructed according to the type described in the introduction, which has expanded lighting possibilities compared to the prior art described above.

[0004] This task is solved according to the invention by a vehicle window panel having the features of claim 1.

[0005] Therefore, according to the present invention, a vehicle window panel is provided, comprising a window panel body assembly and an illumination device having a light source. The window panel body assembly has an outer side facing the vehicle's surrounding environment, an inner side facing the vehicle's interior space, and a surrounding edge comprising two horizontal edges and two vertical edges, the two vertical edges connecting the two horizontal edges to each other. On the inner side of the window panel body assembly, i.e., on the large surface of the window panel body assembly facing the vehicle's interior space, a queerteg is arranged, which connects the two horizontal edges to each other and / or connects the two vertical edges to each other, and the queerteg at least partially receives the illumination device.

[0006] Therefore, in the vehicle window panel according to the invention, additional functional elements are installed in the form of a transverse joint on the inner side of the window panel body assembly. These elements are for lighting purposes, i.e., for directly illuminating specific areas of the vehicle interior space and / or for generating light patterns or the like on the vehicle window panel, i.e., as ambient lighting for the vehicle window panel. This transverse joint, extending through the transparent area of ​​the vehicle window panel, is particularly constructed in the form of a strip that rests against the inner side of the window panel body assembly. The transverse joint also allows for the integration of design elements on the lower side of the vehicle window panel.

[0007] In principle, the window panel assembly of the vehicle window panel according to the present invention can have a composite structure and be implemented as so-called composite safety glass (VSG). However, it is also contemplated that the window panel assembly be implemented as a single-layer window panel or a single-layer safety glass (ESG).

[0008] When using a composite structure as a window panel assembly, it preferably includes an outer window panel and an inner window panel, with the inner window panel attached to the outer window panel via at least one connecting layer. The inner window panel can then form a light guide layer, into which light from a lighting device can be coupled, for example, input. An additional, potentially costly, light guide layer is not required. When operating the lighting device, surface and / or patterned ambient lighting functions can be provided through the inner window panel and the corresponding coupled-input light output.

[0009] To enable suitable integration of lighting devices into the transverse joint of the vehicle window panel according to the invention, in one particular embodiment, the transverse joint has a molded section formed onto or bonded to the inside of the window panel assembly. This molded section forms the base of the transverse joint, allowing for the mounting of elements of the lighting device and, if necessary, the integration of other functions onto the transverse joint. If the transverse joint is molded onto the inside of the window panel assembly, the connection between the window panel assembly and the transverse joint is achieved during the molding process of the transverse joint. Thus, the molded section of the transverse joint is directly attached to the inside of the window panel assembly in the molding die, i.e., after the foaming or injection molding process. In the case of a prefabricated transverse joint, the transverse joint can be secured or held to the inside of the window panel assembly by means of adhesives or tapes, or by means of other fastening devices (which may also be formed by an inner top element or the like).

[0010] The molding section of the transverse joint of the vehicle window panel according to the present invention is preferably formed of polyurethane material.

[0011] In a common embodiment of the vehicle window panel according to the invention, the window panel body assembly has a surrounding edge foam that follows the direction of the surrounding edge of the window panel body assembly. In this case, the molding section of the transverse joint is preferably an integrated component of the edge foam, i.e., the transverse joint is molded together in the same mold when molding the edge foam and is formed of the same material, such as polyurethane.

[0012] For example, in order to fix the light source on the molding section, the molding section of the transverse joint preferably has at least one receiving section in which the light source is at least partially arranged. For example, the light source is secured in the receiving section.

[0013] To facilitate the retention of receiving space for functional elements or similar items used for lighting devices, the transverse joint preferably features a light-shielding panel to form an exterior surface (Sichtfläche), which is particularly removable. Preferably, the light-shielding panel, made of plastic, forms a cover for the transverse joint, visible from the interior of the vehicle. It is conceivable that this light-shielding panel is part of the inner roof.

[0014] In order to direct the light from the light source arranged in the transverse section toward the interior space of the vehicle, in a particular embodiment of the vehicle window panel according to the invention, the transverse section has at least one light-transmitting opening for the light source, which may be provided with a transparent light-transmitting element. This light-transmitting element can be secured, and in particular fixed, to the molded section.

[0015] The penetration opening can be formed by a light shield, through which light can be emitted toward the interior space of the vehicle. The light shield can be secured, for example, by securing it to a locking pin or locking strip, which is formed on a formed section or directly formed or bonded to the inside of the window panel assembly.

[0016] In another specific embodiment of the vehicle window panel according to the invention, the lighting device and / or at least partially receiving the lighting device includes at least one optical coupling input element for optically coupling the light source into the window panel body assembly, wherein the optical coupling input element is received by the transverse joint and / or works in conjunction with the light source, which is a component of the transverse joint.

[0017] The optical coupling input element preferably includes at least one optical prism, which is mounted, and in particular bonded, to the inner side of the window panel assembly, i.e., a large surface in the region of the transverse joint. For optical coupling input, it is preferable to provide multiple prisms arranged sequentially on the inner side of the vehicle window panel in a manner following the transverse joint, either laterally or longitudinally, and each prism interacts with at least one light source or LED. Alternatively, the optical coupling input element may be received by a shaped section.

[0018] In an alternative embodiment of the vehicle window panel according to the invention, the light-coupled input element includes a light-directing film disposed on the side of a light guide layer facing away from the light source, the light guide layer being formed from a layer in the window panel assembly. For example, the window panel assembly includes an outer window panel and an inner window panel, the inner window panel being attached to the outer window panel via a laminate, and a light-directing film disposed on the side of the inner window panel facing the outer window panel, the light-directing film following a transverse joint disposed on the inner side of the window panel assembly. The light-directing film may include, for example, a hologrammfolie or a mikrospiegelfolie, which can couple light from a light source disposed on the inner side of the window panel assembly into the light guide layer formed by the inner window panel and receive the light source.

[0019] The light source of the vehicle window panel according to the invention can be formed in a variety of ways and includes at least one LED, which is preferably a component of an LED strip, an LED bar, an LED module, or a PCB (printed circuit board). Alternatively, the light source can be formed by a laser device.

[0020] In another specific embodiment of the vehicle window panel according to the invention, the light source may include an optical fiber and / or a rope-like light guide. The optical fiber, or in particular the rope-like light guide, is directly or indirectly connected to the inner side of the window panel assembly and coupled to an actual light source, such as an LED or laser. Preferably, it is provided with optical coupling output elements, by means of which light transmitted in the optical fiber or rope-like light guide can be coupled out, for example, towards an optical coupling input element of the aforementioned type, or directly towards a light guide layer of the aforementioned type, or towards a penetration opening in the transverse joint through which light can be emitted towards the vehicle's interior space. Therefore, in the context of this invention, the optical fiber and the rope-like light guide should also be understood as light sources.

[0021] In addition to the functions described above, the vehicle window panel according to the present invention may include a display, which is fixedly or movably supported on the transverse joint.

[0022] Furthermore, it is conceivable that at least one guide rail and / or at least one motor for a functional element, such as a display, are arranged on the transverse section.

[0023] In another specific embodiment of the vehicle window panel according to the invention, the transverse section includes a reading light for vehicle occupants.

[0024] In addition, it is conceivable that the transverse section includes at least one sensor element, which may be a component of a gesture control device for recognizing seat occupancy or a vehicle functional unit.

[0025] Other advantages and advantageous configurations of the subject matter of this invention can be derived from the specification, drawings, and patent claims. Within the scope of this invention, all combinations of at least two features disclosed in the specification, claims, and / or drawings, i.e., each feature mentioned in the specification, can be part of the claimed object independently of other features and embellishments mentioned in their respective contexts.

Figure 10 The corresponding cross-section; and Figure 12 A top view of the transverse joint of a vehicle window panel according to another embodiment is shown. Detailed Implementation

[0027] exist Figure 1 and Figure 2 The diagram shows the roof 10 of a motor vehicle, which is not shown in detail elsewhere. This roof 10 is a panoramic roof, having an adjustable cover element 12 and a fixed roof element 14, which is fixedly or immovably attached to the vehicle structure relative to the vehicle body. The cover element 12 and the fixed roof element 14 each include glass elements that form vehicle window panels and function as ambient lighting. The basic structure of the vehicle window panels of the cover element 12 and the fixed roof element 14 is identical.

[0028] The vehicle window panel of cover element 12 and the vehicle window panel of fixed roof element 14 each include a window panel body assembly 16 constituting composite safety glass (VSG). This window panel body assembly has an outer window panel 18 facing the vehicle's surrounding environment and an inner window panel 20 facing the vehicle's interior space. The inner window panel is connected to the outer window panel 18 via a laminate layer 22. It is conceivable that a liquid crystal assembly, for example configured as a so-called PDLC (polymer dispersed liquid crystal assembly), be additionally arranged between the outer window panel 18 and the inner window panel 20, forming an electrically switchable shielding device for the vehicle window panel.

[0029] The outer window panel 18 forming the outer side of the window panel assembly 16 is a curved glass panel, for example, made of colored soda-lime glass. Alternatively, the outer window panel may be formed of a curved plastic element, such as a curved polycarbonate element. The inner window panel 20 forming the inner side of the window panel assembly 16 can also be made of inorganic glass, such as soda-lime glass, or a polymer, such as polycarbonate.

[0030] from Figure 1 As can be seen, the vehicle window panel of the cover element 12 and the vehicle window panel of the fixed roof element 14 each have a surrounding edge, which includes two transverse sides extending in the vehicle's lateral direction y and two longitudinal sides extending in the vehicle's longitudinal direction x, the two longitudinal sides connecting the two transverse sides to each other. Along the surrounding edge, the vehicle window panel is provided with an edge foam portion 24 made of polyurethane foam material, the edge foam portion following these longitudinal and transverse sides.

[0031] The inner body of the window panel of the cover element 12 and the inner body 20 of the window panel of the fixed roof element 14 each constitute a light guide layer, through which light emitted by the corresponding lighting device 26 and coupled in is propagated. The lighting device 26 is at least partially a component of a transverse joint 28 extending in the longitudinal direction x of the vehicle, which is arranged on the inner side of the window panel assembly 16 and connects the edges of the corresponding window panel or the two transverse sides of the edge foam 24 extending in the transverse direction y of the roof. Therefore, the lighting device 26 extends centrally in the longitudinal direction x of the vehicle through the viewing area of ​​the corresponding window panel.

[0032] from Figure 2 As can be seen, the lighting device 26 includes two lighting strips 30, which are constructed as PCBs (printed circuit boards) in the form of flexible circuit boards, thus forming a circuit board with electronic structural components. Multiple LEDs 32 are arranged in rows on the circuit board of the lighting strips 30 as light sources.

[0033] The lighting devices 26 for the two vehicle window panels each include two rows of optically coupled input elements 34 arranged sequentially in the longitudinal direction x of the vehicle. These optically coupled input elements are wedge-shaped in cross-section and are respectively attached or bonded to the inner side of the large surface of the window panel interior 20. The optically coupled input elements 34, constructed identically, function as optical prisms, allowing light from the LED 32 associated with the corresponding optically coupled input element 34 to be coupled through a coupling surface 36 into the light guide layer formed by the window panel interior, which constitutes the interface with the window panel interior 20. The light from the corresponding LED 32 is coupled through a side surface 37 into the associated optically coupled input element 34.

[0034] On the side facing the outer body 18 of the window panel, a patterned light-coupled output element 40 is printed on the inner body 20 of the window panel. With the help of these light-coupled output elements, light emitted by the LED 32 and coupled into the inner body 20 of the window panel via the light-coupled input element 34 is coupled out in the direction of the vehicle interior space, thereby generating a light pattern on the window panel assembly 16 that corresponds to the light-coupled output element 40 and is visible from the vehicle interior space. Figure 2 The dashed lines in the diagram illustrate an exemplary light path between LED 32 and the vehicle's interior space.

[0035] As can be seen from the attached figures, the lighting device 26 is constructed with at least substantially mirror symmetry about the vertical longitudinal center plane of the roof.

[0036] By centrally arranging the optical coupling input element 34, the number of optical coupling input elements and the complexity of the LED strip can be halved compared to a solution that arranges the optical coupling input elements and LED strips on both sides, which in turn reduces component and manufacturing costs.

[0037] In addition, the transverse joints 28 of the two vehicle window panels each include a sunshade 38, which forms an exterior surface visible from the interior space of the vehicle.

[0038] Figure 3 The vehicle window panel is shown, which is substantially corresponding to the one shown in the original text. Figure 1 and Figure 2 The vehicle window panel differs in that it includes multiple sequentially arranged optical coupling input elements 34, each constructed in a double-wedge shape with respect to the vertical longitudinal center plane of the vehicle. Each element has a centrally located receiving slot 42 extending in the longitudinal direction of the vehicle to receive an illumination strip 30, also constructed as a PCB. LEDs 32 are also arranged in a mirror-symmetrical manner on the illumination strip 30 received by the transverse joint 28, which connects the two transverse edges of the edge foaming section 24. The light from the LEDs can correspond to... Figure 3 The light path shown by the dashed line enters the inner body 20 of the window panel and is coupled out again by the light coupling output element 40 to realize the ambient light function.

[0039] In other respects, Figure 3 The implementation method is corresponding to Figure 2 The implementation method is described herein, therefore, reference to the related description is made to avoid repetition.

[0040] Figure 4 The vehicle window panel is shown, which again substantially corresponds to the one shown in the original text. Figure 1 and Figure 2 The implementation differs in that the vehicle window panel includes a light-coupled input element 34' formed of a light-directing film. This light-directing film is strip-shaped and follows the orientation of a transverse joint 28, which is disposed on the inner side of the window panel body assembly 16 or the window panel inner body 20 and extends centrally in the longitudinal direction between the two transverse sides of the surrounding edge foam portion of the window panel body assembly 16. The light-directing film, configured as a holographic film or micromirror film, is disposed within a glass laminate on the side of the window panel inner body 20 facing the window panel outer body 18, i.e., on the side of the window panel inner body 20 opposite to the transverse joint 28. The transverse joint 28 receives LEDs 32 arranged sequentially in the longitudinal direction, which are disposed on a PCB or LED strip, LED module, or LED band. Furthermore, the transverse joint 28 includes a light-shielding plate 38, which forms the outer surface of the transverse joint 28. Light emitted from LED 32 illuminates the optical coupling input element 34' formed by the light-directing film, and is coupled into the inner body 20 of the window panel forming the light guide layer via this optical coupling input element. The coupled output of light is again achieved through the optical coupling output element 40, which is printed on the side of the inner body 20 facing the outer body 18 of the window panel.

[0041] In other respects, Figure 4 The structure of the vehicle window panel shown is also corresponding to that of the vehicle. Figure 1 and Figure 2 The structure is such that, therefore, to avoid repeating the relevant description, the transverse joint 28 also extends from one edge of the window panel assembly 16 to the other edge.

[0042] exist Figure 5 and Figure 6 The image shows a vehicle window panel 50, which can also be formed as shown in the image. Figure 1 The roof panel of the type shown includes a panel body assembly 16 having a polyurethane edge foam portion 24 on its surrounding edge. The edge foam portion 24 extends circumferentially on the edge of the panel body assembly 16 extending in the vehicle's lateral direction y and longitudinal direction x.

[0043] On the inner side of the window panel assembly 16 facing the vehicle interior space, the vehicle window panel 50 has a transverse joint 52, which includes a molded section 54 as a base. This molded section is integrally manufactured with the edge foam 24 and is therefore also formed of polyurethane material. The molded section 54 extends between the transverse edges of the two edge foams 24 extending in the vehicle's lateral direction y, or connects these two transverse edges to each other. The molded section 54 has a slotted receiver 56 on its lower side, which extends in the longitudinal direction x of the roof and in which a rope-like light guide 58 is arranged. In addition, the molded section 54 has a receiving area 60 for LED modules 62 in the area near the edge foam 24, and the light from these LED modules can be coupled into the light guide 58, i.e., the light guide 58 is connected to the LED modules 62. On the side opposite to the window panel assembly 16, the space of the molded section 54 receiving the light guide 58 is closed by means of a removably secured diffuser 64 that forms a light shield. The light from the LED module 62 is coupled into the light guide 58 and coupled out from thereon on the outer periphery of the light guide 58 by means of a coupling output element not shown in detail, so that it can be used to illuminate the interior space of a vehicle.

[0044] Therefore, in Figure 5 and Figure 6 In the illustrated embodiment, the edge foaming portion 24 and the molding section 54 of the transverse joint portion 28 are integrally manufactured. Simple assembly is ensured by forming corresponding fixing points or locking points to secure the light guide 58, LED module 62, and diffuser plate 64.

[0045] Figure 7 A vehicle window panel 70 is shown, which corresponds to Figure 5 and Figure 6One embodiment includes a window panel assembly 16 with a surrounding edge foam 24. The edge foam 24 extends on a lateral edge of the window panel assembly 16 extending in the vehicle lateral direction y and a longitudinal edge extending in the vehicle longitudinal direction x.

[0046] The edge foaming section 24 is arranged between the edges on the two transverse edges, extending therein. Figure 8 The transverse section 72, shown in more detail, is part of the lighting device and is at least partially integrally formed with the edge foam section 24 onto the window panel assembly 16. Therefore, the transverse section 72, thus at least partially constructed as a molded segment, includes reading lights 74 as lighting devices or light sources, with two reading lights assigned to the front seats and two to the rear seats of the relevant vehicle. Furthermore, the transverse section 72 includes sensor elements 76 that can identify seat occupancy in the interior space of the relevant vehicle, or may be part of a gesture control device for vehicle functions.

[0047] The electronic components of the transverse section 72 can be integrated into the light shield, which is snapped onto the molding section integrally constructed with the edge foaming section 24, or can be integrated into the molding section.

[0048] Furthermore, it is conceivable that the lighting device formed by the reading lamp 74 and received by the transverse joint is received as an insert into the molded section of the transverse joint. Thus, an additional cover or light shield is no longer needed.

[0049] Figure 9 A transverse joint 72 is shown, which may be... Figure 7 An alternative embodiment of the transverse joint of the vehicle window panel of the type shown, and the transverse joint corresponding to Figure 5 The implementation may include an LED module as a light source and a light guide, which are received by a molding section, wherein the molding section is covered by a light shield 78 that follows the basic shape of the molding section, the light shield having a plurality of light-emitting openings or windows 80 arranged in a row. By backlighting the light shield 78, a specific light pattern predetermined by the arrangement of the windows 80 is generated by means of the light guide.

[0050] Figure 10A vehicle window panel 100 is shown, which also includes a window panel body assembly 16 having a surrounding edge foam portion corresponding to the above embodiment. A transverse joint 102 extends between the two transverse sides of the edge foam portion 16, forming an injection-molded or foam-molded housing 104 for a lighting electronics device 105, which is part of the lighting device of the vehicle window panel 100. On the side opposite to the window panel body assembly 16, the transverse joint 102 has a at least partially transparent plastic window 106, which is fixed to the housing 104 by a fastener 108.

[0051] Figure 11 A vehicle window panel 110 is shown, which substantially corresponds to the one shown according to Figure 10 The vehicle window panel, therefore refer to its description. The vehicle window panel 110 is consistent with... Figure 10 The difference in this vehicle window panel lies in that it includes a housing 114 as a transverse joint 112, which connects the relevant transverse edges of the edge foaming portion to each other. The housing 114 is fixed to a mushroom-shaped fixing device or fixing strip 116, which is formed onto the inner side of the window panel body assembly 16. Corresponding to... Figure 10 In one embodiment, the housing 114 covers the components of the lighting electronics 105 of the vehicle window panel 110.

[0052] Figure 10 and Figure 11 The lighting electronics 105 of the illustrated embodiment can be used for backlighting of the plastic window 106 or the housing 114, which may have corresponding openings for light penetration, and / or may work in conjunction with a light-coupled input device, which is configured to... Figures 1 to 4 The type of optical coupling input element shown is constructed.

[0053] Figure 12 A transverse joint 122 is shown, which may, for example, replace... Figure 9 The transverse joint shown is used and also has a light-emitting opening or window 80 for generating light patterns. Furthermore, a display 124 is supported on the transverse joint 122, meaning that the display can pivot about an axis extending in the vehicle's lateral direction y and can translate in the vehicle's longitudinal direction x. For this purpose, a drive motor 126 and a guide rail 128 are constructed on the transverse joint 122.

[0054] In other respects, the transverse joint 122 corresponds to the following: Figure 9 The transverse joint, therefore refer to the relevant description.

[0055] Thanks to the central structure of the transverse connector 28, in the above embodiment, power only needs to be supplied to the centrally located lighting device. No wiring is required along the edges of the vehicle window panels. This results in a manufacturing cost advantage.
