Description
Technical Field
The present utility model relates generally to a glass panel assembly for a roof assembly of a vehicle. In particular, the present utility model relates to a glass panel assembly provided with at least one light incoupling assembly. Such a glass panel assembly may be particularly useful for providing patterned illumination of a passenger compartment of a vehicle.
Background
In existing glass panel assemblies, an additional glass layer is required on top of the base glass layer, which is smaller than the base glass layer in top view, because light in-coupling is achieved from the sides of the glass, and thus should provide sufficient space for positioning of the light in-coupling assembly. Such existing glass panel assemblies may include layered glass panels in which two or even three individual glass panels are stacked upon one another.
Disclosure of Invention
It is an object of the present utility model to provide an improved glass panel assembly of this type.
Thus, according to a first aspect of the present utility model, there is provided a glass panel assembly intended for a roof assembly of a vehicle and having a laminated glass panel comprising a first glass panel having a first glass panel upper surface and an opposing first glass panel lower surface and a second glass panel having a second glass panel upper surface and an opposing second glass panel lower surface, wherein the first and second glass panels are laminated to each other at the first and second glass panel lower surfaces by a lamination layer, and wherein at least one light incoupling assembly (light incoupling assembly) is provided on the second glass panel lower surface, the light incoupling assembly comprising at least one light source having light incoupling elements, and wherein the light incoupling elements comprise right angle prisms (rectangular prism).
The glass panel assembly according to the utility model combines many advantageous features such as low weight, high strength and very efficient light incoupling into the glass panel.
In one embodiment of the glass panel assembly, the right angle prism is made primarily of super transparent glass. This optimizes the light incoupling into the glass panel (in particular reduces the light losses).
In such embodiments, the right angle prism is preferably attached to the lower surface of the second glass panel by a layer of optical adhesive. Such an optical adhesive combines the following advantageous features: an effective bond between the prism and the lower surface of the second glass panel is achieved and an effective transmission (in-coupling) of light into the second glass panel is ensured. The layer of optical adhesive may extend over the entire respective surface of the prism facing the lower surface of the second glass panel (and in such a case, the respective surface of the prism preferably will be planar or substantially planar).
To further improve light in-coupling, the layer of optical adhesive may be an ultra-thin layer.
Basically, the laminated glass panels can be of two different types. As a first type, the laminated glass panel may be a fixed panel, wherein a bead of glue is provided near the periphery of the lower surface of the second glass panel for connecting the laminated glass panel to a part of the vehicle (e.g. a frame part of a roof assembly or a so-called body-in-white of the vehicle) and for defining a watertight seal with respect to a part of the vehicle. Thus, in such embodiments, the glass panel has a fixed position relative to the vehicle.
Alternatively, as a second type, the laminated glass panel may be a movable panel, wherein the perimeter of the lower surface of the second glass panel is intended to cooperate directly or indirectly (e.g. via an encapsulation around at least a part of the outer edge of the second glass panel) with a seal provided on a part of the vehicle (e.g. a frame part of a roof assembly or a so-called body-in-white of the vehicle). Such a movable panel may be used, for example, for closing and opening a roof opening provided in a stationary roof part of a vehicle.
Preferably, the first and second glass panels are provided with the same or substantially the same contour as seen in a top plan view. This has a particularly advantageous effect on the overall strength of the laminated glass panel.
Further, it is conceivable that the first glass panel and the second glass panel have the same or substantially the same thickness, for example, a thickness of substantially 2.1 mm.
In a further embodiment of the glass panel assembly according to the utility model, the light outcoupling means (light outcoupling provision) are arranged in a desired pattern at the interface between the upper surface of the second glass panel and the laminate layer. Such light outcoupling means may ensure that the light is visible at a desired location (e.g. for generating a desired light pattern) with a desired brightness (e.g. from inside the passenger compartment of the vehicle). The light outcoupling means may be part of the laminate layer and/or the second glass panel or may be integrated into (or positioned on top of) the laminate layer and/or the second glass panel, but may also be a separate device positioned therebetween. The desired pattern may be such that the devices are arranged according to a local pattern only, but it is also conceivable that such devices are arranged continuously over at least a part of the interface.
In a second aspect, the utility model relates to a roof assembly of a vehicle comprising a frame part surrounding a roof opening in a roof part of the vehicle and a glass panel assembly according to the foregoing fixedly or movably mounted in the frame part.
Drawings
The utility model will be described with reference to the accompanying drawings, in which:
FIG. 1 schematically illustrates a portion of a vehicle in which a glass panel assembly according to the present utility model may be incorporated;
FIG. 2 schematically illustrates a top plan view of a portion of the vehicle;
fig. 3 schematically shows a partial cross-section according to III-III in fig. 2; and
fig. 4 schematically shows a partial cross-section according to IV-IV in fig. 2.
Detailed Description
In fig. 1, a roof section of a vehicle 1 is shown, which has a stationary roof section 2, to which stationary roof section 2 a frame section 3 (only shown in fig. 3) is mounted, the inner side of the frame section 3 surrounding (or defining) a roof opening 4. One part (e.g. the front part) of the roof opening 4 is covered by a movable panel 5, while the remaining part (e.g. the rear part) of the roof opening is covered by a fixed panel 6.
In fig. 2, the movable panel 5 and the fixed panel 6 are schematically shown in their respective positions relative to the fixed roof part 2. Of course, the movable panel 5 may be moved to another position (e.g., partially rearward over the fixed panel 6) to at least partially release a corresponding portion of the roof opening 4. The mechanisms for effecting such movement of the movable panel 5 are well known in the art and will not be further described herein.
As an exemplary embodiment, both the movable panel 5 and the fixed panel 6 define a laminated glass panel that is part of a glass panel assembly according to the present utility model and will be described in detail with reference to fig. 3 and 4. However, it should be noted that in other embodiments, only one of the movable panel and the fixed panel may define such a laminated glass panel.
In fig. 2, the light incoupling components 7a-d and 8a-d are schematically indicated with dashed lines. Such light incoupling components may be arranged in any desired pattern (e.g. at all edges of the panels 5, 6 as shown, or e.g. only at some edges, e.g. only at the side edges of the panels, and thus only 7a, b and 8a, b, and in a similar way for two panels or in a different way for two panels). Although the position of the light incoupling component near the edges of the panels 5, 6 is preferred as schematically shown in fig. 2, other positions are also conceivable.
For a detailed description of a laminated glass panel defining a portion of the fixed panel 6, reference is made to fig. 3. The laminated glass panel includes a laminate having: a first (here upper) glass panel 9 having a first glass panel upper surface 10 and an opposite first glass panel lower surface 11; and a second (here lower) glass panel 12 having a second glass panel upper surface 13 and an opposing second glass panel lower surface 14.
The first glass panel 9 and the second glass panel 12 are laminated to each other at the first glass panel lower surface 11 and the second glass panel upper surface 13 by a lamination layer 15. Such laminate layer 15 may be of any known type and may have characteristics selected according to the particular application.
Fig. 3 also shows a light incoupling component 8a arranged on the lower surface 14 of the second glass panel. The light incoupling component 8a (and any other light incoupling components) comprises at least one light source 16 having light incoupling elements 17. The light incoupling elements 17 comprise in particular right-angle prisms, which may be made mainly of ultra-transparent glass.
In the illustrated embodiment, the right angle prism 17 is attached to the second glass panel lower surface 14 by a layer of optical adhesive 18, which is preferably ultra thin. The light source 16 may be attached to the second glass panel 12 in any suitable manner.
A bead 19 of glue or the like is provided near the periphery of the lower surface 14 of the second glass panel for connecting the laminated glass panel 6 with a part of the vehicle, such as the frame part 3 (or alternatively, the so-called body-in-white) in the illustrated embodiment, which frame part 3 may surround the roof opening 4, as previously described, and for defining a watertight seal with respect to the part of the vehicle.
As seen in a top plan view, the first and second glass panels 9, 12 are provided with the same or substantially the same contour, as partially illustrated in fig. 3 by the fact that the right-hand outer edges of the first and second glass panels 9, 12 substantially coincide.
Not illustrated in detail is a light out-coupling device that may be provided in a desired pattern at the interface between the second glass panel upper surface 13 and the laminate layer 15, which may ensure that light is emitted from the second glass panel 12 at a desired location (as schematically illustrated by arrow 20).
Fig. 4 differs from fig. 3 essentially only in that the laminated glass panel now defines a part of the movable panel 5. Components similar to those of the fixed panel 6 according to fig. 3 have the same reference numerals. The main difference is that a package 21 is provided at the edge of the movable panel 5, a cover element 22 (for hiding the light incoupling component 7a from view) and a part 23 of the drive mechanism for the movable panel 5 are attached to said package 21. A seal 24 (visible only in fig. 2) may be provided on a part of the vehicle for cooperation with, for example, the package 21 (or another part of the movable panel 5).
In the embodiment according to fig. 3 and 4, the first glass panel 9 and the second glass panel 12 have the same or substantially the same thickness, for example a thickness of substantially 2.1 mm. The two panels may be made of the same or different glass materials.
The utility model is not limited to the described embodiments, which may vary widely within the scope of the present utility model as defined by the attached claims.
