Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a window assembly and a vehicle. Background Technology

[0002] As vehicle technology continues to advance and people's demands for driving experience increase, some vehicles are equipped with ambient lighting on their windows to enhance the overall quality and ambiance of the interior. For example, ambient lights installed near the sunroof emit light that, when powered on, is guided through a light guide structure to the sunroof glass, displaying luminous patterns. When not powered on, these patterns are mostly invisible. However, in related technologies, the light guide structure has low light-guiding efficiency, resulting in low brightness of the illuminated patterns, making them almost invisible to occupants during the day. Summary of the Invention

[0003] The purpose of this application is to provide a window assembly and vehicle that can improve the light guiding efficiency of the light guiding structure and increase the brightness of the pattern light emission.

[0004] In a first aspect, embodiments of this application provide a vehicle window assembly, including:

[0005] The vehicle window glass includes an inner glass surface and a light extraction layer;

[0006] A housing, the housing being connected to the inner glass surface;

[0007] A light guide includes a first surface, a second surface, a third surface, a fourth surface, and a fifth surface. The first surface and the fifth surface are disposed opposite to the fourth surface along the thickness direction of the light guide. The fifth surface is located between the first surface and the fourth surface. The connection position of the second surface and the third surface forms an angle. The second surface and the third surface are located on the same side of the width direction of the light guide. The third surface is connected to the fourth surface, and the second surface is connected to the first surface.

[0008] A light source, wherein the light emitted by the light source includes a first light ray and a second light ray;

[0009] The light guide is located between the light source and the window glass, and along the width direction of the window assembly. The light guide is located on one side of the pattern shape. The first surface is opposite to the inner glass surface of the window glass. The second and third surfaces face the light source and are spaced apart from the light source.

[0019] In one embodiment, the vehicle window glass includes an inner glass panel, an outer glass panel, and an intermediate layer. The outer glass panel, the intermediate layer, and the inner glass panel are stacked along the vehicle window glass, and the surface of the inner glass panel facing away from the outer glass panel is the inner glass surface.

[0020] The window assembly also includes a light-guiding adhesive layer, which is connected to the fifth surface and the inner glass surface. The first light and the second light are emitted from the fifth surface and then enter the inner glass panel through the light-guiding adhesive layer and are conducted within the inner glass panel.

[0021] The difference in refractive index between the light-guiding adhesive layer and the inner glass plate is less than 0.02.

[0022] In one embodiment, the light guide includes an end face, which is disposed opposite to the second and third faces along the width direction of the light guide. The end face is connected to the fifth and fourth faces, and the fifth face is connected to the first face.

[0023] The difference in refractive index between the light-guiding adhesive layer and the light-guiding component is less than 0.02.

[0024] In one embodiment, the light guide is made of glass or plastic.

[0025] In one embodiment, the light guide further includes a first light guide and a second light guide. The first light guide and the second light guide are arranged opposite to each other and spaced apart along the width direction of the light guide. The first light guide includes a first surface, a second surface, a third surface, a fourth surface, and a first opposing surface connected between the first surface and the fourth surface. Along the width direction of the first light guide, the second surface and the third surface are arranged opposite to the first opposing surface. The second light guide includes a fifth surface and a second opposing surface connected to the fifth surface. The fifth surface is a surface in the thickness direction of the second light guide and is spaced apart from the first surface. The second opposing surface is a surface in the width direction of the second light guide, and the second opposing surface and the first opposing surface are arranged opposite to each other and spaced apart along the width direction of the light guide.

[0026] In one embodiment, the difference in refractive index of the light guide adhesive layer and the second light guide element is less than 0.02.

[0027] In one embodiment, the second light guide is made of glass, and the first light guide is made of plastic.

[0028] In one embodiment, the distances from the second and third surfaces of the light guide to the light source are both greater than or equal to 1 mm and less than or equal to 2 mm.

[0029] In one embodiment, the transmittance of the light extraction layer is greater than or equal to 80% and less than or equal to 90%, and the reflectance is greater than or equal to 8% and less than or equal to 12%.

[0030] In one embodiment, the window assembly further includes a circuit board, a first adhesive, and a second adhesive.

The light source is disposed on the circuit board and is in communication with the circuit board.

[0031] In one embodiment, the thickness of the window assembly is less than or equal to 20 mm.

[0032] In one embodiment, the light extraction layer has a patterned shape, and the first light and the second light are reflected by the light extraction layer to make the patterned shape emit light.

[0033] Secondly, embodiments of this application provide a vehicle, the vehicle including a body body and the aforementioned window assembly, the window assembly being mounted on the body body.

[0034] In related technologies, the arrangement of the light guide structure and ambient lights, as well as the structural design of the light guide structure, result in only a small portion of the light emitted by the ambient lights entering the sunroof glass through the light guide structure, leading to low light guiding efficiency. For example, if the ambient light is located on the side of the light guide structure along its width, the light emitted by the ambient light enters from the side of the light guide structure and then enters the sunroof glass. Simulation tests show that the effective output luminous intensity of the ambient light emitted by the light guide structure is approximately 0.116777 cd. A significant portion of the light emitted by the ambient light does not reach the sunroof glass, resulting in low brightness of the illuminated pattern, making it almost invisible during the day and affecting the usability of the ambient light.

[0035] In this embodiment, the light guide and the light source are arranged opposite to each other and spaced apart along the thickness direction of the window assembly. The light source emits light, and most of the light enters the window glass through the light guide. The first light rays converge twice on the second and first surfaces of the light guide before entering the inner glass plate of the window glass, and the second light rays converge once on the third surface of the light guide before entering the inner glass plate of the window glass. Simulation tests show that the effective output light intensity of the light guide to the light source is approximately 0.185482 cd. Compared with the effective output light intensity of ambient light in the light guide structure of the prior art, the effective output light intensity of the light source is increased by at least 2.54 times, greatly improving the utilization rate of the light emitted by the light source and thus greatly improving the brightness of the illuminated pattern.

The vehicle 1000 can be, but is not limited to, a sedan, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a van, a bus, a truck, etc. In the specific embodiment of this application, the vehicle 1000 is taken as a sedan.

[0046] For ease of description, in this application, the width direction of vehicle 1000 is defined as the X-axis direction, the length direction as the Y-axis direction, and the height direction as the Z-axis direction; wherein the X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0047] It should be noted that the directional terms such as "top," "bottom," "left," "right," "front," and "back" used in the description in this application are based on the appendix to the specification. Figure 1 and attached Figure 2 The orientation of the vehicle 1000 is described with the forward direction along the length of the vehicle 1000 as the positive direction of the X-axis, the direction from left to right along the width of the vehicle 1000 as the positive direction of the Y-axis, and the direction away from the ground along the width of the vehicle 1000 as the positive direction of the Z-axis.

[0048] In this embodiment, the vehicle 1000 includes a window assembly 100 and a vehicle body 300. The window assembly 100 is mounted on the vehicle body 300. Figure 1 and Figure 2As shown, the window assembly 100 includes a window glass 10, which includes an inner glass surface and an outer glass surface. The outer glass surface and the inner glass surface are arranged opposite to each other along the thickness direction of the window glass 10. When the window assembly 100 is installed on the vehicle body 300, the inner glass surface of the window glass 10 faces the interior of the vehicle 1000, and the outer glass surface of the window glass 10 faces the exterior of the vehicle 1000.

[0049] The vehicle window glass 10 can be a side window, sunroof, rear windshield, or front windshield of the vehicle 1000. Correspondingly, the vehicle window assembly 100 can be a side window assembly, sunroof assembly, rear windshield assembly, or front windshield assembly. In this embodiment, the vehicle window glass 10 is described and illustrated using a sunroof as an example, and the vehicle window assembly 100 is illustrated using a sunroof assembly as an example.

[0050] It should be noted that the window glass 10 can be a flat plate, or it can be curved or arc-shaped, or the shape of the window glass 10 can be any shape that meets the usage requirements of the window assembly 100, not limited to the shapes described above. In this embodiment, as... Figure 2 As shown, the window glass 10 is illustrated using a curved surface as an example. The window glass 10 can be tempered glass.

[0051] like Figure 2 As shown, the window assembly 100 also includes a housing 14. The housing 14 is located inside the vehicle 1000. Along the Z-axis, the housing 14 is disposed around the edge of the window glass 10 and covers the inner glass surface of the window glass 10. A receiving space is formed between the housing 14 and the window glass 10.

[0052] Please refer to the following: Figure 2 , Figure 3 and Figure 4 , Figure 3 for Figure 2 The diagram shows a partial cross-sectional view of a first embodiment of the window assembly. Figure 4 for Figure 3 The diagram shows an exploded cross-section of a portion of the window assembly.

[0053] In this embodiment, the window assembly 100 further includes a light guide 15, a light source 16, a light guide adhesive layer 17, a circuit board 18, a first adhesive layer 19, and a second adhesive layer 20. The circuit board 18, the light source 16, and the light guide 15 are all located within the receiving space enclosed by the housing 14 and the window glass 10, to protect the light guide 15, the light source 16, and the circuit board 18. The light guide 15 is connected to the inner glass surface of the window glass 10 via the light guide adhesive layer 17. The circuit board 18 is fixedly connected to the housing 14 via the first adhesive layer 19, and the light source 16 is disposed on the circuit board 18 and electrically connected to it. The light source 16 and the light guide 15 are arranged opposite to each other and spaced apart along the thickness direction of the window assembly 100. The circuit board 18 is electrically connected to the light source 16 and an external power source, and controls the opening and closing of the light source 16. When the light source 16 is powered on, the light source 16 emits light. Some of the light enters the light guide 15, and after being reflected and converged by the light guide 15, it enters the car window glass 10 through the light guide adhesive layer 17 for conduction.

[0054] In this embodiment, both the first adhesive 19 and the second adhesive layer are made of 3M adhesive. The light source 16 can be an LED or other types of light source. The light guide 15 can be made of plastic or glass. The light guide adhesive layer 17 is made of optical adhesive. For example, the light guide 15 is made of glass. The light source 16 is an OSRAM KRTBID2LM31.31 LED.

[0055] In this embodiment, the cross-section of the light guide 15 is approximately arc-shaped. The light guide 15 includes a first surface 151, a second surface 152, a third surface 153, a fourth surface 154, an end surface 157, and a fifth surface 155 connected sequentially. It should be noted that... Figure 3 and Figure 4 The dashed line on the light guide 15 represents the boundary between the first surface 151 and the fifth surface 155.

[0056] like Figure 3 and Figure 4As shown, the first surface 151 is connected to one side of the fifth surface 155 in the width direction, and the first surface 151 and the fifth surface 155 are smoothly connected. The end surface 157 is connected to the other side of the fifth surface 155 in the width direction, and is set at an angle to the fifth surface 155. The side of the end surface 157 away from the fifth surface 155 is connected to the fourth surface 154, and the end surface 157 and the fourth surface 154 are set at an angle. The first surface 151 and the fourth surface 154 are set opposite to each other along the thickness direction of the light guide 15. The fifth surface 155 is located between the first surface 151 and the fourth surface 154. In this embodiment, the first surface 151 and the fifth surface 155 are located on the same side of the thickness direction of the light guide 15, and the first surface 151 and the fifth surface 155 are set opposite to the fourth surface 154 along the thickness direction of the light guide 15. The second surface 152 and the third surface 153 are connected, and the connection position of the second surface 152 and the third surface 153 forms an angle. The second surface 152 and the third surface 153 are both located on one side of the width direction of the light guide 15, and are positioned opposite to the end surface 157 along the width direction of the light guide 15. The second surface 152 and the third surface 153 are located between the first surface 151 and the fourth surface 154. The first surface 151 is connected to the second surface 152 and is set at an angle to the second surface 152. The second surface 152 and the third surface 153 are used for the incident light, serving as the incident surface of the light. The first surface 151 is used to reflect and converge the light incident through the second surface 152. The fifth surface 155 is used for the exit of the light. The fourth surface 154 serves to define the boundary of the light incident through the third surface 153, serving as the boundary surface of the light.

[0057] In this embodiment, end face 157 and fifth face 155 are both planar. First face 151, second face 152, third face 153, and fourth face 154 are all curved surfaces. The curved direction of the first face 151 is approximately the same as that of the fourth face 154. The first face 151 convexes outward in the thickness direction of the light guide 15, and the fourth face 154 is concave in the thickness direction of the light guide 15. The second face 152 and the third face 153 are both convex curved surfaces, and their convex direction is approximately the width direction of the light guide 15. The curved direction of the second face 152 intersects with that of the first face 151. The curved direction of the third face 153 intersects with that of the fourth face 154. The first face 151, second face 152, third face 153, and fourth face 154 form a "W" shape. It can be understood that the second face 152 and the third face 153 of the light guide 15 can be considered as convex surfaces for light rays, and the light rays converge after incident on the convex surfaces. The first surface 151 can be considered as a concave surface for light rays. Light rays that converge after passing through the second surface 152 are reflected and then converge again upon entering the first surface 151. The fourth surface 154 can be considered as a convex surface. Light rays that converge after passing through the third surface 153 are transmitted to the fourth surface 154 and then diverged by the fourth surface 154.

[0058] The circuit board 18 has a first mounting surface 181 and a second mounting surface 182. The first mounting surface 181 and the second mounting surface 182 are disposed opposite to each other along the thickness direction of the circuit board 18. In this embodiment, the circuit board 18 is a printed circuit board assembly (PCBA), and its materials include FR4, Ni, and Cu, etc.

[0059] The housing 14 includes a first mounting surface 141 and a second mounting surface 142. The first mounting surface 141 and the second mounting surface 142 are disposed opposite to each other along the thickness direction of the housing 14. The housing 14 also has a groove 143, with the first mounting surface 141 forming the groove surface of the groove 143. It is understood that the groove 143 has a bottom surface and a side surface, with the bottom surface connected to the side surface and opposite to the opening of the groove 143. The first mounting surface 141 forms the bottom surface and the side surface of the groove 143. In this embodiment, the housing 14 can be made of polycarbonate and acrylonitrile-butadiene-styrene copolymer. Figure 2 As shown, in one embodiment, the groove 143 is an annular groove. The groove 143 is disposed around the edge of the window glass 10. This application does not limit the shape of the groove 143 of the housing 14, as long as it meets the actual application requirements.

[0060] The vehicle window glass 10 is a laminated glass structure. The vehicle window glass 10 includes an outer glass panel 12, an intermediate layer 13, and an inner glass panel 11. Along the thickness direction of the vehicle window glass 10, the outer glass panel 12, the intermediate layer 13, and the inner glass panel 11 are sequentially stacked and connected. When the vehicle window assembly 100 is installed on the vehicle body 300, the outer glass panel 12 faces outwards from the vehicle 1000, and the inner glass panel 11 faces inwards from the vehicle 1000.

[0061] The inner glass panel 11 includes a first surface 111 and a second surface 112. The first surface 111 and the second surface 112 are arranged opposite to each other along the thickness direction of the inner glass panel 11. When the vehicle window glass 10 is installed on the vehicle body 300, the first surface 111 of the inner glass panel 11 faces the interior of the vehicle 1000, serving as the inner surface of the inner glass panel 11 and the inner glass surface of the vehicle window glass 10. The second surface 112 of the inner glass panel 11 faces away from the interior of the vehicle 1000, serving as the outer surface of the inner glass panel 11.

[0062] The outer glass panel 12 includes a third surface 121 and a fourth surface 122. The third surface 121 and the fourth surface 122 are arranged opposite to each other along the thickness direction of the outer glass panel 12. When the vehicle window glass 10 is installed on the vehicle body 300, the fourth surface 122 of the outer glass panel 12 faces the outside of the vehicle 1000, serving as the outer surface of the outer glass panel 12 and the outer glass surface of the vehicle window glass 10. The third surface 121 of the outer glass panel 12 faces away from the outside of the vehicle 1000, serving as the inner surface of the outer glass panel 12.

[0063] The interlayer 13 is located between the third surface 121 of the outer glass panel 12 and the second surface 112 of the inner glass panel 11, and the interlayer 13 connects the third surface 121 of the outer glass panel 12 and the second surface 112 of the inner glass panel 11. The interlayer 13 is used to bond the outer glass panel 12 and the inner glass panel 11 together to form a laminated glass structure, improve the structural strength of the vehicle window glass 10, prevent glass shards from flying and injuring the driver or passengers inside the vehicle 1000 after the outer glass panel 12 and the inner glass panel 11 break, and enable the vehicle window glass 10 to meet more safety standards and regulatory requirements.

[0064] The vehicle window glass 10 also includes a light extraction layer x. The light extraction layer x is sandwiched between the inner glass plate 11 and the intermediate layer 13, and is connected to the second surface 112 of the inner glass plate 11. The light extraction layer x has a patterned shape. The reflectivity of the light extraction layer x is 8%–12% (including endpoint values ​​of 8% and 12%), and the transmittance of the light extraction layer x is 80%–90% (including endpoint values ​​of 80% and 90%). When the light source 16 is not energized, the patterned shape of the light extraction layer x is transparent, i.e., the patterned shape is not visible. When the light source 16 is energized, the light emitted by the light source 16 is incident on the light extraction layer x and diffusely reflected within the inner glass plate 11. When the angle of incidence of light is less than the angle of total internal reflection within the inner glass plate 11, this portion of the light exits from the first surface 111 of the inner glass plate 11, allowing occupants inside the vehicle 1000 to see the pattern shape, thus creating an ambient lighting effect. When the angle of incidence of light is greater than the angle of total internal reflection within the inner glass plate 11, this portion of the light continues to be conducted within the inner glass plate 11. The material used for the light extraction layer x is, for example, ink, such as an ink coating or an ink printing layer. This application does not impose strict limitations on this.

[0065] like Figure 3 and Figure 4As shown, the light guide 15 is mounted on the vehicle window glass 10. Along the width direction of the vehicle window assembly 100, the light guide 15 is located on one side of the patterned shape of the light extraction layer x. Along the thickness direction of the vehicle window assembly 100, the light guide adhesive layer 17 connects the fifth surface 155 of the light guide 15 and the first surface 111 of the inner glass panel 11 to fix the light guide 15 to the vehicle window glass 10. The first surface 151 of the light guide 15 is opposite to and spaced from the first surface 111 of the inner glass panel 11. The first surface 151 of the light guide 15 extends away from the vehicle window glass 10. The shape of the light guide adhesive layer 17 is adapted to the shape of the inner glass surface of the vehicle window glass 10 and the shape of the fifth surface 155 of the light guide 15. The size of the light guide adhesive layer 17 is adapted to the size of the fifth surface 155 of the light guide 15. The thickness of the light guide adhesive layer 17 is greater than or equal to 1 mm and less than or equal to 2 mm, and the width of the light guide adhesive layer 17 is greater than or equal to 15 mm and less than or equal to 25 mm.

[0066] Circuit board 18 and light source 16 are mounted in housing 14. Both circuit board 18 and light source 16 are located within recess 143 of housing 14. Light source 16 is connected to first mounting surface 181 of circuit board 18. Second mounting surface 182 of circuit board 18 faces the bottom surface of recess 143. First adhesive 19 is connected to the second mounting surface 182 of circuit board 18 and the bottom surface of recess 143 to fix circuit board 18, which contains light source 16, to housing 14.

[0067] A housing 14, containing a circuit board 18 and a light source 16, is mounted on a window glass 10 containing a light guide 15. The first mounting surface 141 of the housing 14 faces the inner glass panel 11 of the window glass 10. A second adhesive member 20 connects the first mounting surface 141 of the housing 14 and the first surface 111 of the inner glass panel 11 to fix the housing 14 to the window glass 10. The groove 143 of the housing 14 faces the first surface 111 of the inner glass panel 11, and the groove 143 of the housing 14 and the window glass 10 form a receiving space. The light guide 15 is located within the receiving space M. Along the thickness direction of the window assembly 100, the second surface 152 and the third surface 153 of the light guide 15 both face the light source 16, and the second surface 152 and the third surface 153 are spaced apart from the light source 16. For example, the distances from the second surface 152 and the third surface 153 to the light source 16 are greater than or equal to 1 mm and less than or equal to 2 mm. This not only ensures that the light guide 15 will not come into contact with the light source 16 and cause damage to the light source 16, but also ensures the amount of light entering the light guide 15 from the light source 16, thereby improving the light guide efficiency of the light guide 15.

[0068] In this embodiment, the light guide 15 is curved towards the window glass 10. That is, the first surface 151 and the fourth surface 154 of the light guide 15 protrude towards the window glass 10. The thickness of the window assembly 100 is less than or equal to 20mm to avoid the window assembly 100 occupying too much space in the vehicle 1000.

[0069] like Figure 2 and Figure 3 As shown, when the light source 16 is energized, it emits light in all directions. Taking a plane OO passing through the center point of the light source 16 (i.e., the center point where the light source 16 emits light) and perpendicular to the width direction of the light source 16 as a reference, the direction perpendicular to the plane OO is defined as the first direction L. The positive direction of the first direction L points towards the center plane BB of the window glass 10 in the width direction (center plane BB and...). Figure 1 (The mid-surfaces AA are perpendicular to each other). The light emitted from the light source 16 forms an angle α with the plane OO. When the angle between the light ray and the positive direction of the first direction L is an acute angle or a right angle, the angle α between the light ray and the plane OO is 0° to 90° (inclusive of the endpoint values ​​of 0° and 90°). When the angle between the light ray and the first direction L is an obtuse angle, the angle α between the light ray and the plane OO is 0° to -90° (inclusive of the endpoint value of -90°). For example, as... Figure 3 As shown, the angle α between the ray on the right side of plane OO and plane OO is 0° to 90°, and the angle between the ray on the left side of plane OO and plane OO is 0° to -90°.

[0070] In this embodiment, the light emitted by the light source 16 includes a first light ray 161 and a second light ray 162. The angle α between the first light ray 161 and the plane OO is a first angle α1, which is greater than or equal to -50° to -30° and less than or equal to 30° to 50°. The first light ray 161 is incident on the fifth surface 155 of the light guide 15 at an angle of incidence greater than the critical angle of the material of the light guide 15. Specifically, the first light ray 161 enters the light guide 15 through the second surface 152. Since the second surface 152 is a convex arc surface, the first light ray 161 converges after passing through the second surface 152 and is conducted to the first surface 151 of the light guide 15. The first light ray 161 conducted to the first surface 151 is reflected. Since the first surface 151 is an arc surface, the first light ray 161 converges after passing through the first surface 151 and is conducted to the fifth surface 155 of the light guide 15. The first light ray 161 conducted to the fifth surface 155 exits through the fifth surface 155 and enters the first surface 111 of the inner glass plate 11 through the light guide adhesive layer 17.

[0071] In this embodiment, the critical angle for total internal reflection of the first ray 161 in the inner glass plate 11 is 76.8°. The tilt angle β formed by the first ray 161 after convergence by the first surface 151 and the first surface 111 of the inner glass plate 11 is less than the critical angle for total internal reflection of the first ray 161 in the inner glass plate 11.

[0072] The angle α between the second ray 162 and the plane OO is the second angle α2, which is greater than or equal to 30° to 50°. The second ray 162 is incident on the fifth surface 155 of the light guide 15 at an angle greater than the critical angle of the material of the light guide 15. Specifically, the second ray 162 enters the light guide 15 through the third surface 153. Since the third surface 153 is a convex arc surface, the second ray 162 converges after passing through the third surface 153 and is conducted to the fifth surface 155 of the light guide 15. The second ray 162 conducted to the fifth surface 155 exits through the fifth surface 155 and enters the first surface 111 of the inner glass plate 11 through the light guide adhesive layer 17. The fourth surface 154 defines the boundary of the second ray 162 conducted to the fifth surface 155 (blocking the second ray 162 from exiting the light guide 15 from the fourth surface 154), thus avoiding the loss of light from the light source 16 entering the light guide 15.

[0073] In this embodiment, both the first light ray 161 and the second light ray 162 are incident at an angle greater than the critical angle of the material of the light guide 15 to the fifth surface 155 of the light guide 15 and exit through the fifth surface 155. The first light ray 161 and the second light ray 162 exit through the light guide adhesive layer 17 and enter the first surface 111 of the inner glass plate 11. Then, they are oscillating and transmitted between the second surface 112 and the first surface 111 of the inner glass plate 11, so that the pattern shape on the light extraction layer x emits light. Among them, a portion of the first light ray 161 and the second light ray 162 are reflected by the light extraction layer x connected to the second surface 112 of the inner glass plate 11. The portion of the light reflected by the light extraction layer x continues to oscillate and transmit between the second surface 112 and the first surface 111 of the inner glass plate 11, so that the light is transmitted to the pattern shape on the light extraction layer x away from the light guide 15. Another portion of the first light ray 161 and the second light ray 162 are scattered by the light extraction layer x connected to the second surface 112 of the inner glass plate 11. The portion of the light scattered by the light extraction layer x is emitted at an angle less than the critical angle of the material of the inner glass plate 11, forming a luminous pattern that can be observed by the personnel inside the vehicle 1000.

[0074] It should be noted that, in order to facilitate the distinction between the light guide 15 and the light inside the window glass 10, the light emitted by the light source 16 entering the light guide 15 is divided into a first light ray 161 and a second light ray 162. The first light ray 161 and the second light ray 162 each represent a beam of light, but in reality, more than one beam of light enters the light guide 15. Figure 3The solid arrows are meant to represent the light rays 161 and 162 entering the window glass 10 through the light guide 15 and the light guide adhesive layer 17, and do not represent all the light rays actually passing through the light guide 15 and the window glass 10.

[0075] In this embodiment, the refractive indices of the inner glass plate 11, light guide 15, and light guide adhesive layer 17 of the vehicle window glass 10 are similar, with the difference between the refractive indices of the inner glass plate 11 and the light guide adhesive layer 17 being less than 0.02. More preferably, the difference between the refractive indices of the inner glass plate 11 and the light guide adhesive layer 17 is less than 0.01. The difference between the refractive indices of the light guide adhesive layer 17 and the light guide 15 is less than 0.02, and more preferably, the difference between the refractive indices of the light guide adhesive layer 17 and the light guide 15 is less than 0.01. This ensures that light rays with a critical angle greater than that of the light guide 15 material can be incident on the fifth surface 155 of the light guide 15 and enter the inner glass plate 11 through the light guide adhesive layer 17, thereby improving the utilization rate of light and reducing the loss of light rays passing through the light guide 15 and the light guide adhesive layer 17. For example, the refractive index of the window glass 10, the light guide 15, and the light guide adhesive layer 17 is 1.52.

[0076] In related technologies, the arrangement of the light guide structure and ambient lights, as well as the structural design of the light guide structure, result in only a small portion of the light emitted by the ambient lights entering the sunroof glass through the light guide structure, leading to low light guiding efficiency. For example, if the ambient light is located on the side of the light guide structure along its width, the light emitted by the ambient light enters from the side of the light guide structure and then enters the sunroof glass. Simulation tests show that the effective output luminous intensity of the ambient light emitted by the light guide structure is approximately 0.116777 cd. A significant portion of the light emitted by the ambient light does not reach the sunroof glass, resulting in low brightness of the illuminated pattern, making it almost invisible during the day and affecting the usability of the ambient light.

[0077] In this embodiment, the light guide 15 and the light source 16 are arranged opposite to each other and spaced apart along the thickness direction of the window assembly 100. The light source 16 emits light, and most of the light enters the window glass 10 through the light guide 15. The first light ray 161 converges twice between the second surface 152 and the first surface 151 of the light guide 15 before entering the inner glass plate 11 of the window glass 10. The second light ray 162 converges once between the third surface 153 of the light guide 15 before entering the inner glass plate 11 of the window glass 10. Simulation tests show that the effective output light intensity of the light guide 15 to the light source 16 is approximately 0.185482 cd. Compared with the effective output light intensity of ambient light in the prior art, the effective output light intensity of the light guide 15 to the light source 16 is increased by at least 2.54 times, greatly improving the utilization rate of the light emitted by the light source 16 by the light guide 15, thereby greatly improving the brightness of the luminous pattern.

[0078] Please see Figure 5 , Figure 5 for Figure 2 A partial cross-sectional schematic diagram of the second embodiment of the window assembly shown.

[0079] In this embodiment, the structure of the light guide 15 differs from that in the first embodiment. The light guide 15 in this embodiment includes a first light guide 15a and a second light guide 15b. The second light guide 15b is laminated and connected to the window glass 10 via a light guide adhesive layer 17. Both the first light guide 15a and the light source 16 are disposed on the circuit board 18, and are positioned opposite to and spaced apart along the thickness direction of the window assembly 100. The first light guide 15a and the second light guide 15b are positioned opposite to and spaced apart along the width direction of the window assembly 100. When the light source 16 is powered on, the light source 16 emits light. Part of the light enters the first light guide 15a, is reflected and converged by the first light guide 15a and then emitted, and then enters the second light guide 15b, the light guide adhesive layer 17 connected to the second light guide 15b and the inner glass plate 11 of the car window glass 10 in sequence.

[0080] In this embodiment, the first light guide 15a includes a first surface 151, a sixth surface 156, a second surface 152, a third surface 153, a fourth surface 154, and a first opposing surface 158a connected sequentially. The sixth surface 156 is connected to the first surface 151 and the second surface 152, and is arranged at an angle to the first surface 151 and the second surface 152. The sixth surface 156, the second surface 152, and the third surface 153 of the first light guide 15a are all located on the same side of the width direction of the first light guide 15a, and are all arranged opposite to the first opposing surface 158a along the width direction of the first light guide 15a. The first opposing surface 158a is located between the first surface 151 and the fourth surface 154, and is connected to the first surface 151 and the fourth surface 154.

[0081] In this embodiment, the first light guide 15a is made of plastic. The sixth surface 156 and the first opposing surface 158a are both planar. The arcuate curvature directions of the first surface 151 and the fourth surface 154 are approximately the same. The first surface 151 convexes outwards in the thickness direction of the first light guide 15a, while the fourth surface 154 is concave in the thickness direction of the first light guide 15a. The second surface 152 and the third surface 153 are both convex arcuate surfaces in the width direction of the first light guide 15a, and the convex directions of the second surface 152 and the third surface 153 intersect. The connection point of the second surface 152 and the third surface 153 forms an included angle.

[0082] In this embodiment, the second light guide 15b is made of glass. The cross-section of the second light guide 15b is approximately rectangular. The second light guide 15b includes a second opposing surface 158b and an end surface 157, which are arranged opposite to each other along the width direction of the second light guide 15b. The second light guide 15b also includes a fifth surface 155 and a light guiding surface 159, which are arranged opposite to each other along the thickness direction of the second light guide 15b. The fifth surface 155 and the light guiding surface 159 are connected to the second opposing surface 158b and the end surface 157.

[0083] It is understood that the light guide 15 in this embodiment is divided into a first light guide 15a and a second light guide 15b. Compared with the light guide 15 in the first embodiment described above, the light guide 15 in this embodiment includes, in addition to the first surface 151, the second surface 152, the third surface 153, the fourth surface 154, the fifth surface 155, and the end surface 157, a sixth surface 156, a first opposing surface 158a, a second opposing surface 158b, and a light guide surface 159. Along the thickness direction of the light guide 15, the first surface 151 and the fourth surface 154 are arranged opposite to each other, and the fifth surface 155 and the light guide surface 159 are arranged opposite to each other. The fifth surface 155 and the light guide surface 159 are located between the first surface 151 and the fourth surface 154. The fifth surface 155 is spaced apart from the first surface 151, and the fifth surface 155 and the first surface 151 are located on the same side of the thickness direction of the light guide 15. The light guide surface 159 and the fourth surface 154 are spaced apart, and the light guide surface 159 and the fourth surface 154 are located on the opposite side of the thickness direction of the light guide 15. The second surface 152, the third surface 153, and the sixth surface 156 are arranged opposite to the end surface 157 along the width direction of the light guide 15. The end surface 157 is connected to the fifth surface 155 and the light guide surface 159.

[0084] like Figure 5 As shown, the second light guide 15b is mounted on the vehicle window glass 10. The fifth surface 155 of the second light guide 15b faces the inner glass panel 11 of the vehicle window glass 10. A light-guiding adhesive layer 17 connects the fifth surface 155 of the second light guide 15b and the first surface 111 of the inner glass panel 11 to fix the second light guide 15b to the vehicle window glass 10. The shape of the light-guiding adhesive layer 17 is adapted to the shape of the fifth surface 155 of the second light guide 15b and the shape of the first surface 111 of the inner glass panel 11. The size of the light-guiding adhesive layer 17 is adapted to the size of the second light guide 15b. For example, the thickness of the second light guide 15b is 2.1 mm. The thickness of the light-guiding adhesive layer 17 is 1.5 mm.

[0085] Circuit board 18, light source 16, and first light guide 15a are all mounted in housing 14. Circuit board 18, light source 16, and first light guide 15a are all located in groove 143 of housing 14. Light source 16 and first light guide 15a are both connected to circuit board 18. For example, light source 16 is attached to the first mounting surface 181 of circuit board 18 by adhesive. The second surface 152, third surface 153, and sixth surface 156 of first light guide 15a all face the first mounting surface 181 of circuit board 18, and the second surface 152 and third surface 153 are spaced apart from light source 16. The sixth surface 156 of first light guide 15a is provided with rivets or rivet posts (not shown), so that first light guide 15a can be fixedly connected to circuit board 18 by thermal riveting. The second mounting surface 182 of the circuit board 18 faces the bottom surface of the groove 143. The first adhesive 19 is connected to the second mounting surface 182 of the circuit board 18 and the bottom surface of the groove 143 to fix the circuit board 18, which is equipped with the first light guide 15a and the light source 16, to the housing 14.

[0086] A housing 14, containing a circuit board 18, a light source 16, and a first light guide 15a, is mounted on a window glass 10 containing a second light guide 15b. The first mounting surface 141 of the housing 14 faces the inner glass panel 11 of the window glass 10. A second adhesive 20 connects the first mounting surface 141 of the housing 14 and the first surface 111 of the inner glass panel 11 to securely attach the housing 14 to the window glass 10. The second light guide 15b is located within a recess 143 in the housing 14. The first opposing surfaces 158a of the first light guide 15a and the second opposing surfaces 158b of the second light guide 15b are positioned opposite each other and spaced apart along the width direction of the window assembly 100. The first surface 151 of the first light guide 15a faces the first surface 111 of the inner glass panel 11 and is positioned opposite and spaced apart from the first surface 111.

[0087] like Figure 5 As shown, when the light source 16 is powered on, it emits light in all directions. The first light ray 161 enters the first light guide 15a through the second surface 152. Because the second surface 152 is a convex arc surface, the first light ray 161 converges after passing through the second surface 152 and is conducted to the first surface 151 of the first light guide 15a. The first light ray 161, after reaching the first surface 151, is reflected. Because the first surface 151 is an arc surface, the first light ray 161 converges after passing through the first surface 151 and is conducted to the first opposing surface 158a of the first light guide 15a. The first light ray 161, after reaching the first opposing surface 158a, exits through the first opposing surface 158a and enters the second light guide 15b through the second opposing surface 158b. The first light ray 161, after entering the second light guide 15b, enters the first surface 111 of the inner glass plate 11 through the fifth surface 155 and the light-guiding adhesive layer 17 of the second light guide 15b.

[0088] The second light ray 162 enters the first light guide 15a through the third surface 153. Since the third surface 153 is a convex arc surface, the second light ray 162 converges after passing through the third surface 153 and is conducted to the first opposing surface 158a of the first light guide 15a. The second light ray 162 conducted to the first opposing surface 158a exits through the first opposing surface 158a and enters the second light guide 15b through the second opposing surface 158b. The second light ray 162 entering the second light guide 15b passes through the fifth surface 155 of the second light guide 15b and the light guide adhesive layer 17 and enters the first surface 111 of the inner glass plate 11. The fourth surface 154 defines the boundary of the second light ray 162 that converges to the first opposing surface 158a, so as to prevent the second light ray 162 from exiting the first light guide 15a from the fourth surface 154, thus avoiding the loss of light from the light source 16 entering the first light guide 15a.

[0089] It should be noted that the refractive indices of the inner glass plate 11, the second light guide 15b, and the light guide adhesive layer 17 of the vehicle window glass 10 are similar, with the difference in refractive indices between the inner glass plate 11 and the light guide adhesive layer 17 being less than 0.02, and more preferably, less than 0.01. The difference in refractive indices between the light guide adhesive layer 17 and the second light guide 15b is less than 0.02, and more preferably, less than 0.01, to ensure that light rays with a material critical angle greater than that of the second light guide 15b can be incident on the fifth surface 155 of the second light guide 15b and enter the inner glass plate 11 via the light guide adhesive layer 17, thereby improving the utilization rate of light and reducing light loss after passing through the second light guide 15b and the light guide adhesive layer 17. Furthermore, in this embodiment, the same structures, effects, and processes as in the first embodiment described above will not be repeated here.

[0090] In some embodiments, unlike the structure of the window assembly 100 in the first and second embodiments described above, the window glass 10 in this embodiment can also be a single-layer glass structure, comprising a glass plate. The glass plate includes an inner glass surface and an outer glass surface, which are arranged opposite to each other along the thickness direction of the glass plate. A light-guiding adhesive layer 17 is connected to the fifth surface 155 of the light guide 15 and the inner glass surface of the glass plate. The first light ray 161 and the second light ray 162 are emitted through the fifth surface 155 of the light guide 15 and enter the inner glass surface through the light-guiding adhesive layer 17, and are conducted within the glass plate. The refractive indices of the light-guiding adhesive layer 17, the glass plate, and the light guide 15 are close. The difference in refractive indices between the light-guiding adhesive layer 17 and the glass plate is less than 0.02, and more preferably, the difference in refractive indices between the glass plate and the light-guiding adhesive layer 17 is less than 0.01. The difference in refractive index between the light-guiding adhesive layer 17 and the light guide element 15 is less than 0.02. More preferably, the difference in refractive index between the light-guiding adhesive layer 17 and the light guide element 15 is less than 0.01, so as to ensure that light rays with a refractive index greater than the material critical angle of the light guide element 15 can be incident on the fifth surface 155 of the light guide element 15 and enter the glass plate through the light-guiding adhesive layer 17, thereby improving the utilization rate of light and reducing the loss of light rays passing through the light guide element 15 and the light-guiding adhesive layer 17.

[0091] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
