Description

Window panel, window panel assembly and vehicle

Technical Field

The present invention relates to the technical field of vehicle windows, and in particular to a vehicle window panel, a vehicle window panel assembly and a vehicle.

Background technique

In traditional car window products, the main way of light incidence is to install a light source on the end face of the glass (end, cut face, end face of partially dug glass), and the light emitted by the light source enters the glass layer (specifically the optical waveguide layer) through the end face and propagates. Among them, the light source is reflected by the light guide, including the inclined surface made of PMMA (polymethyl methacrylate), PC (polycarbonate), PA (polyamide), COC (cyclic olefin copolymer) or COP (cyclic olefin polymer) (the light source light is incident on the light guide), and the light guide is fixed on one surface of the glass layer through an adhesive layer, and the light source light is incident on the optical waveguide layer. At the same time, the light guide is separated from the main surface by the adhesive layer. The light incident through the light guide is totally reflected in the optical waveguide layer, and then propagates in the optical waveguide layer.

However, conventional car windows have at least the following defects: On the one hand, the design structure of the light guide is complex, especially the contact surface of the light guide facing the glass requires the design of a complex optical structure to assist the light to enter the glass. The light guide includes a series of asymmetric prisms, the size of which is in the millimeter range or micrometer range, and is arranged in a three-dimensional array or linear manner, such as a Fresnel lens. It is difficult to process, manufacture and install, and when the size is large, it will occupy a large amount of external space of the optical waveguide layer. On the other hand, the light guide is installed on the curved glass, which increases the difficulty of the process and the stability of product performance. In addition, the light source's emitting angle needs to be designed synchronously to match the light guide in order to achieve the light entry effect, and the final light source incident efficiency is not high.

Summary of the invention

Based on this, it is necessary to overcome the defects of the prior art and provide a window panel, a window panel assembly and a vehicle, which can simplify the structure, reduce the difficulty of processing, improve production efficiency, have good installation stability, and improve the incident efficiency of the light source.

In one embodiment, h:a:b=1:8:200.

In one embodiment, the vehicle window panel further includes an outer glass layer; the second main surface is connected to the outer glass layer via a first adhesive layer.

A vehicle window panel assembly comprises the vehicle window panel and a covering component, wherein the covering component is used for covering the outside of the light-introducing medium and the light source.

Detailed ways

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

Referring to FIG. 1, FIG. 2 and FIG. 6, FIG. 1 shows a schematic diagram of the structure of a vehicle window panel according to an embodiment of the present invention, FIG. 6 shows a top view of the structure shown in FIG. 1, and FIG. 2 shows a schematic diagram of the structure of a vehicle window panel according to another embodiment of the present invention. A vehicle window panel provided in an embodiment of the present invention comprises: an optical waveguide medium layer 10, a light guide medium 20, and a light source 30. Optionally, the optical waveguide medium layer 10 includes but is not limited to an optical waveguide glass layer. The optical waveguide medium layer 10 is provided with a first main surface 11 and a second main surface 12 opposite to each other. Among them, a light reflection layer 13 is provided on the first main surface 11 or the second main surface 12, or a light reflection layer 13 is provided on each of the first main surface 11 and the second main surface 12 (as shown in FIG. 2). The light guide medium 20 comprises a first surface 21 and a second surface 22 arranged parallel to each other, and the light guide medium 20 is closely connected to the first main surface 11 through the first surface 21, and the connection part of the first main surface 11 connected to the first surface 21 is parallel to the first surface 21. The light source 30 is, for example, an LED light-emitting component, which is located at one end of the light-introducing medium 20 . The light from the light source 30 enters the light-introducing medium 20 . The light-introducing medium 20 is used to introduce the light from the light source 30 into the optical waveguide medium layer 10 .

It should be noted that the first surface 21 and the first main surface 11 are “closely connected”, which means that there is no other layer between the first surface 21 and the first main surface 11 to achieve close “contact” connection, or the first surface 21 and the first main surface 11 are closely connected through other layers such as bonding or locking.

Among them, the light reflecting layer 13 can be arranged as a whole on the second main surface 12, or it can exist in any form of pattern, including but not limited to multiple triangles, multiple water drop shapes, multiple stars, multiple quadrilaterals, multiple circles, multiple ellipses and other regular shapes and irregular shapes. Its specific shape can be flexibly adjusted and designed according to actual needs.

In the above-mentioned window panel, since the light-introducing medium 20 includes a first surface 21 and a second surface 22 arranged parallel to each other, the light-introducing medium 20 is closely connected to the first main surface 11 through the first surface 21, and the connection part of the first main surface 11 connected to the first surface 21 is parallel to the first surface 21, so that when the light of the luminous light source 30 enters the light-introducing medium 20, the light-introducing medium 20 can realize that the light of the luminous light source 30 is incident on the optical waveguide medium layer 10, so that the light propagates in the optical waveguide medium layer 10, and the propagated light encounters the light reflection layer 13 made in advance to generate reflection, and the light reflection layer 13 emits light to achieve lighting or atmosphere effect. In this way, the atmosphere or lighting effect is achieved by the light reflection layer 13, the light-introducing medium 20, and the optical waveguide medium layer 10. In addition, the structure of the light-introducing medium 20 is simplified, the processing difficulty is reduced, the production efficiency is improved, the installation stability on the first main surface 11 of the optical waveguide medium layer 10 is good, and the incident efficiency of the luminous light source 30 is improved.

In addition, the light introduction method of the light-introducing medium 20 has the same light entry effect as the light entry method of the end face (end, cut face) of the third glass layer in the related art.

In addition, under the same functional conditions, the two-piece sandwich product structure assisted by the light-guiding medium 20 can replace the three-piece sandwich product in the related technology, reduce product weight, reduce resource utilization, and greatly reduce production costs.

Secondly, the light reflecting layer 13 can be flexibly arranged according to actual needs. It can be arranged on the first main surface 11, or on the second main surface 12, or a light reflecting layer 13 can be provided on both the first main surface 11 and the second main surface 12, so that the light can be reflected to the inside of the vehicle, thereby achieving lighting or atmosphere effects.

Optionally, the first surface 21 and the second surface 22 each include but are not limited to flat surfaces, curved surfaces or arc-shaped surfaces designed to be parallel to each other, or surfaces of other regular and irregular shapes, which are not limited here and can be flexibly adjusted and set according to actual needs.

In order to make the connection part of the first main surface 11 and the first surface 21 closely connected, the connection part of the first main surface 11 is adapted to the first surface 21. Specifically, when the first surface 21 is a straight surface, the connection part of the first main surface 11 is set to a straight surface; when the first surface 21 is an arcuate surface, the connection part of the first main surface 11 is set to an arcuate surface; when the first surface 21 is a curved surface, the connection part of the first main surface 11 is set to a curved surface.

Please refer to FIG. 3 and FIG. 4, which are schematic diagrams of the structures of the window panels of the other two embodiments of the present invention. The difference between FIG. 3 and FIG. 4 is that the fourth surface 24 is set in a different manner. In one embodiment, the light-introducing medium 20 further includes a third surface 23 and a fourth surface 24 arranged opposite to each other. The light source 30 is arranged adjacent to the third surface 23, and the light of the light source 30 enters the light-introducing medium 20 through the third surface 23. The third surface 23 and the fourth surface 24 are each arranged as a flat surface or an arc surface or other surfaces of regular and irregular shapes, which can be flexibly adjusted and arranged according to actual needs, and are not limited here. In addition, the third surface 23 and the fourth surface 24 can be designed to be parallel to each other, or they do not need to be designed to be parallel to each other, which can be flexibly adjusted and arranged according to actual needs, and are not limited here. During operation, since the light source 30 is arranged adjacent to the third surface 23, when the light source 30 emits light, the light generated is incident toward the third surface 23, enters the light-introducing medium 20, and is introduced into the optical waveguide medium layer 10 by the light-introducing medium 20.

Optionally, the fourth surface 24 may be perpendicular to the first main surface 11 (as shown in FIG. 3 ), or may be arranged at an angle with the first main surface 11 (as shown in FIG. 4 ), and the angle includes but is not limited to an acute angle or an obtuse angle.

Please refer to FIG. 1 . In one embodiment, the first main surface 11 and/or the second main surface 12 of the optical waveguide medium layer 10 are provided with an optical isolation layer and/or a heat-insulating film layer. In this way, an optical isolation layer, such as a UV-blocking, infrared-blocking, anti-reflection coating layer or a chemical coating, can be added to the first main surface 11 and/or the second main surface 12; the above can isolate the harmful light bands when the sun is irradiated, and reduce the damage of harmful light to the vehicle interior and personnel. A heat-insulating film layer, such as a LOW-E heat-insulating film layer, can also be added, for example, in summer, it can effectively isolate the external heat of the vehicle from entering the vehicle, and in winter, it can effectively preserve the heat inside the vehicle.

Please refer to FIG. 1 . In one embodiment, a transparent area is provided at the connection portion of the first main surface 11 connected to the first surface 21. The transparent area is the first main surface 11 where no additional processing is performed at the connection portion. In this way, the transparent area needs to be free of other additional functional film layers. If there are additional functional film layers similar to the above, the area needs to be cleared to ensure that the light-introducing medium 20 is in direct contact with the first main surface 11.

Please refer to FIG. 1 or FIG. 2, which shows a schematic diagram of the structure of a vehicle window panel according to another embodiment of the present invention. Compared with FIG. 1, in the structure shown in FIG. 2, the light-introducing medium 20 is directly connected to the optical waveguide medium layer 10 to form, for example, an integrated structure, that is, obtained by integrated molding. Of course, the light-introducing medium 20 and the optical waveguide medium layer 10 are manufactured separately and assembled together.

The light-introducing medium 20 can be made of the same material as the optical waveguide medium layer 10 or different materials. The material can be flexibly adjusted and configured according to actual needs, and is not limited here.

Optionally, when the refractive index and transmittance properties of the light-introducing medium 20 and the optical waveguide medium layer 10 are the same, the light-introducing medium 20 and the optical waveguide medium layer 10 into which the light is incident can be understood as the same medium on the light propagation surface, that is, the light is well incident from the light-introducing medium 20 to the optical waveguide medium layer 10.

Please refer to Figure 1 or Figure 2. In one embodiment, when the light-guiding medium 20 and the optical waveguide medium layer 10 are manufactured separately and assembled together, the light-guiding medium 20 and the first main surface 11 of the optical waveguide medium layer 10 have the same profile (such as both are planes or single arc surfaces or hyperbolic surfaces composed of cross arc surfaces, etc.). The secondary light-guiding medium 20 can be molded (such as hot pressing molding or hot gravity molding) or cold molding to make it consistent with the profile of the assembly area of the optical waveguide medium layer 10, and then the light-guiding medium 20 and the first main surface 11 of the optical waveguide medium layer 10 are connected to each other.

Please refer to FIG1 , in one embodiment, when the light-introducing medium 20 and the optical waveguide medium layer 10 are manufactured separately and assembled together, a liquid 25 with a certain viscosity can also be used, and the liquid 25 can be cured by light or heat to combine the light-introducing medium 20 with the optical waveguide medium layer 10. Specifically, the liquid 25 can be, but is not limited to, optically clear adhesive (OCA), liquid optical clear adhesive (LOCA), or optically clear resin (OCR).

Optionally, the refractive index of the liquid 25 material is 1.45-1.65, preferably 1.48-1.55; the visible light transmittance (TL) of the liquid 25 material is 90%-99.9%, preferably 97%-99.9%; the haze of the liquid 25 material is ≦5%, preferably ≦1%.

In a specific embodiment, the refractive index, transmittance (TL), and haze of the liquid 25, the light-introducing medium 20, and the optical waveguide medium layer 10 are completely consistent, so that light can be incident from the light-introducing medium 20 into the optical waveguide medium layer 10 better.

In one embodiment, the light-introducing medium 20 and the optical waveguide medium layer 10 are made of the same glass material or different glass materials, which is not limited here. Optionally, the glass material includes but is not limited to inorganic glass or organic glass.

Specifically, the light-introducing medium 20 can be made of the same glass material as the optical waveguide medium layer 10, for example, by directly cutting a flat material, and then by hot-molding a mold to fix and combine it with the optical waveguide medium layer 10 at the connection part with the same profile. In this way, the light can be incident from the light-introducing medium 20 to the optical waveguide medium layer 10 better.

In one embodiment, the refractive index of the light-introducing medium 20 is 1.45-1.65; and/or the light transmittance of the light-introducing medium 20 is 80%-99.9%; and/or the haze of the light-introducing medium 20 is ≦5%.

Specifically, the refractive index of the light-introducing medium 20 is 1.48 to 1.55; the light transmittance of the light-introducing medium 20 is 85% to 99.9%; and the haze of the light-introducing medium 20 is ≦1%.

In one embodiment, the light-introducing medium 20 is connected to the circumference, one side, two sides, or three sides of the optical waveguide medium layer 10 , or any other region that can be constructed.

1 and 6 , in one embodiment, the light-introducing medium 20 is in the shape of a long strip or an arc strip. Thus, the shape of the light-introducing medium 20 is simple and does not need to be made into a wedge shape or a special optical structure.

Please refer to FIG. 5 . In one embodiment, the light propagation distance of the optical waveguide medium layer 10 is defined as b, the distance between the third surface 23 and the fourth surface 24 of the light-introducing medium 20 is a, and the distance between the first surface 21 of the light-introducing medium 20 and the first main surface 11 of the optical waveguide medium layer 10 is h; wherein, b≈20a-30a, preferably b≈22a-28a, more preferably b≈24a-26a, a≈6h-10h, preferably a≈7h-9h. Thus, a and h are not designed in size within this range. If the design is too small, the amount of incident light will be insufficient. If the design is too large, the amount of incident light will not increase, which will lead to waste of materials and space. In addition, in the overall structure after the light-introducing medium 20 and the optical waveguide glass window are assembled together, the distance a is small, the distance h is small, and the occupied area is small, so it is convenient to arrange and use.

In a specific embodiment, the relationship between the size design (spacing a and spacing h) of the light-introducing medium 20 and the distance b required for light propagation in the optical waveguide medium layer 10 satisfies: h:a:b≈1:8:200. This size design of the light-introducing medium 20 will enable the light emitted by the light source 30 to be introduced into the optical waveguide medium layer 10 with maximum efficiency.

For example, it can be known that the required light propagation distance b of the optical waveguide medium layer 10 is 600 mm, and the distance a between the third surface 23 and the fourth surface 24 of the light-introducing medium 20 is ≈ 25 mm, and the distance h between the first surface 21 and the second surface 22 of the light-introducing medium 20 is ≈ 3 mm. That is, the width of the light-introducing medium 20 is 24 mm, and the height is 3 mm. The light-introducing medium 20 of this size will allow the light emitted by the LED light source to be introduced into the optical waveguide medium layer 10 with maximum efficiency.

Referring to FIG. 1 , in one embodiment, the vehicle window panel further comprises an outer glass layer 40. The second main surface 12 is connected to the outer glass layer 40 via a first adhesive layer 50. The outer glass layer 40 is closer to the vehicle exterior, and the optical waveguide medium layer 10 is closer to the vehicle interior. When the light source emits light, the light reflecting layer 13 can be observed to emit light outside the vehicle.

Optionally, the first adhesive layer 50 includes but is not limited to ethylene polyvinyl acetate.

Please refer to FIG. 7 and FIG. 8, which respectively show the structural schematic diagrams of the window panel assemblies of the other two embodiments of the present invention. Compared with the structure shown in FIG. 1, in one embodiment, a window panel assembly includes the window panel of any of the above embodiments, and a cover assembly 60, which is used to cover the outside of the light-introducing medium 20 and the light source 30. In this way, the light-introducing medium 20 and the light source 30 are shielded and protected by the cover assembly 60.

Please refer to FIG. 7 , optionally, the cover assembly 60 is bonded and fixed on the first main surface 11 of the optical waveguide medium layer 10 through a second bonding layer 70 .

Please refer to Figure 8. In another embodiment, the covering component 60 is bonded and fixed to the first main surface 11 of the optical waveguide medium layer 10 through the second adhesive layer 70 on one side, and bonded and fixed to the second surface 22 of the light-introducing medium 20 on the other side. This design can reduce the occupancy of the first main surface 11 of the optical waveguide medium layer 10, and the structure is compact.

Please refer to FIG. 1 and FIG. 6 . In one embodiment, a vehicle includes the window panel assembly of any one of the above embodiments.

In the above-mentioned vehicle, since the light-guiding medium 20 includes a first surface 21 and a second surface 22 arranged parallel to each other, the light-guiding medium 20 is closely connected to the first main surface 11 through the first surface 21, and the connection part of the first main surface 11 connected to the first surface 21 is parallel to the first surface 21, so that when the light of the luminous light source 30 enters the light-guiding medium 20, the light-guiding medium 20 can realize that the light of the luminous light source 30 is incident on the optical waveguide medium layer 10, so that the light propagates in the optical waveguide medium layer 10, and the propagated light encounters the light reflection layer 13 made in advance to generate reflection, and the light reflection layer 13 emits light to achieve lighting or atmosphere effect. In this way, the atmosphere or lighting effect is achieved by the light reflection layer 13 cooperating with the light-guiding medium 20 and the optical waveguide medium layer 10. In addition, the structure of the light-guiding medium 20 is simplified, the processing difficulty is reduced, the production efficiency is improved, the installation stability on the first main surface 11 of the optical waveguide medium layer 10 is good, and the incident efficiency of the luminous light source 30 is improved.

In addition, the light introduction method of the light-introducing medium 20 has the same light entry effect as the light entry method of the end face (end, cut face) of the third glass layer in the related art.

In addition, under the same functional conditions, the two-piece sandwich product structure assisted by the light-guiding medium 20 can replace the three-piece sandwich product in the related technology, reduce product weight, reduce resource utilization, and greatly reduce production costs.
