Description

Technical Field

[0002] With the continuous development of vehicle technology, people's requirements for driving experience are constantly increasing. Some vehicles are provided with ambient lights on the windows to enhance the overall texture inside the vehicle and set off the atmosphere inside the vehicle. For example, an ambient light is installed near the skylight glass. The light emitted by the ambient light when powered on is conducted to the skylight glass through a light guiding structure, and a glowing pattern is presented on the skylight glass. When the ambient light is not powered on, most of the patterns for emitting light are invisible. However, in the related art, the light guiding efficiency of the light guiding structure is low, and the brightness of the pattern for emitting light is low, so that the passengers inside the vehicle can hardly see the glowing pattern during the day.

For example, when the ambient light is located on the side in the width direction of the light guide structure, the light emitted by the ambient light enters the light guide structure from the side and then enters the sunroof glass. Through simulation tests, the effective output light intensity of the light guide structure for the light of the ambient light is about 0.116777 cd. A large part of the light emitted by the ambient light still fails to be conducted to the sunroof glass, resulting in a low brightness of the illuminated pattern and being almost invisible during the day, which affects the use of the ambient light.

Through simulation tests, the effective output light intensity of the light guide member for the light of the light source is about 0.185482 cd. Compared with the effective output light intensity of the light guide structure for the light of the ambient light in the prior art, the effective output light intensity of the light guide member for the light 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 by the light guide member, and thus greatly increasing the brightness of the illuminated pattern.

As 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] Wherein, the window glass 10 can be a side window glass, a sunroof glass, a rear windshield, a front windshield, etc. of the vehicle 1000. Correspondingly, the window assembly 100 can be a side window assembly, a sunroof assembly, a rear windshield assembly, a front windshield assembly, etc. In the embodiments of the present application, the window glass 10 is described and illustrated by taking the sunroof glass as an example, and the window assembly 100 is described and illustrated by taking the sunroof assembly as an example.

[0050] It should be noted that the window glass 10 can be in a flat plate shape, or the window glass 10 can also be in a curved surface or arc shape, or the shape of the window glass 10 can also be not limited to the aforementioned shapes, and it can be any shape that meets the use requirements of the window assembly 100. In this embodiment, as Figure 2 shown, the window glass 10 is illustrated by taking the arc shape as an example. The window glass 10 can be tempered glass.

[0051] As Figure 2 shown, the window assembly 100 further includes a housing 14. The housing 14 is located inside the vehicle 1000. Along the Z-axis direction, the housing 14 is arranged 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 Figure 2 、 Figure 3 and Figure 4 , Figure 3 is Figure 2 a partial cross-sectional schematic view of the first embodiment of the window assembly shown, Figure 4 is Figure 3 a disassembled cross-sectional schematic view of the partial structure of the window assembly shown.

[0053] In this embodiment, the window assembly 100 further includes a light guide member 15, a light source 16, a light guide adhesive layer 17, a circuit board 18, a first bonding member 19, and a second bonding member 20. The circuit board 18, the light source 16, and the light guide member 15 are all located in the accommodation space formed by the housing 14 and the window glass 10 to protect the light guide member 15, the light source 16, and the circuit board 18. The light guide member 15 is connected to the inner glass surface of the window glass 10 through the light guide adhesive layer 17. The circuit board 18 is fixedly connected to the housing 14 through the first bonding member 19. The light source 16 is disposed on the circuit board 18 and is electrically connected to the circuit board 18. The light source 16 and the light guide member 15 are opposite 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 light source 16 to turn on and off. When the light source 16 is powered on, the light source 16 emits light. Part of the light enters the light guide member 15, and after being reflected and converged by the light guide member 15, it enters the window glass 10 through the light guide adhesive layer 17 for conduction.

[0054] In this embodiment, the materials of the first bonding member 19 and the second bonding layer are both 3M glue. The light source 16 can be an LED or other types of light sources. The light guide member 15 can be made of plastic or glass. The material of the light guide adhesive layer 17 is optical glue. Exemplarily, the light guide member 15 is made of glass. The model of the light source 16 is an LED lamp of OSRAM KRTBID2LM31.31.

[0055] In this embodiment, the cross-section of the light guide member 15 is generally arc-shaped. The light guide member 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 that are connected in sequence. It should be noted that Figure 3 and Figure 4 the dotted line located on the light guide member 15 represents the dividing line between the first surface 151 and the fifth surface 155.

[0056] As Figure 3 and Figure 4As shown, the first surface 151 is connected to one side in the width direction of the fifth surface 155, and the first surface 151 and the fifth surface 155 are smoothly connected. The end surface 157 is connected to the other side in the width direction of the fifth surface 155 and is arranged at an angle with 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 is arranged at an angle with the fourth surface 154. The first surface 151 and the fourth surface 154 are arranged back to back along the thickness direction of the light guide member 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 on the same side in the thickness direction of the light guide member 15, and the first surface 151 and the fifth surface 155 are arranged back to back with the fourth surface 154 along the thickness direction of the light guide member 15. The second surface 152 and the third surface 153 are connected, and an angle is formed at the connection position of the second surface 152 and the third surface 153. Both the second surface 152 and the third surface 153 are on one side in the width direction of the light guide member 15 and are arranged back to back with the end surface 157 along the width direction of the light guide member 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 arranged at an angle with the second surface 152. The second surface 152 and the third surface 153 are for the incidence of light and are the light incident surfaces. The first surface 151 is used to reflect and converge the light incident through the second surface 152. The fifth surface 155 is for the emergence of light. The fourth surface 154 is used to demarcate the boundary of the light incident through the third surface 153 and is the light boundary surface.

[0057] In this embodiment, both the end surface 157 and the fifth surface 155 are flat surfaces. The first surface 151, the second surface 152, the third surface 153, and the fourth surface 154 are all arc surfaces. The arc bending directions of the first surface 151 and the fourth surface 154 are substantially the same. The first surface 151 protrudes outward in the thickness direction of the light guide member 15, and the fourth surface 154 is concave inward in the thickness direction of the light guide member 15. Both the second surface 152 and the third surface 153 are convex arc surfaces, and the protruding direction is substantially the width direction of the light guide member 15. The arc bending direction of the second surface 152 intersects with that of the first surface 151. The arc bending direction of the third surface 153 intersects with that of the fourth surface 154. The first surface 151, the second surface 152, the third surface 153, and the fourth surface 154 form a "W" shape. It can be understood that the second surface 152 and the third surface 153 of the light guide member 15 can be regarded as convex surfaces for light, and the light converges after entering the convex surface. The first surface 151 can be regarded as a concave surface for light, and the light converged by the second surface 152 is incident on the first surface 151 and is reflected and converged. The fourth surface 154 can be regarded as a convex surface, and the light converged by the third surface 153 is conducted to the fourth surface 154 and is 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 arranged 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 18 (Printed Circuit Board Assembly, PCBA), and its materials include FR4, Ni, 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 arranged opposite to each other along the thickness direction of the housing 14. The housing 14 also has a groove 143, and the first mounting surface 141 is the groove surface of the groove 143. It can be understood that the groove 143 has a groove bottom surface and a groove side surface, the groove bottom surface is connected to the groove side surface and is opposite to the groove opening of the groove 143. The first mounting surface 141 forms the groove bottom surface and the groove side surface of the groove 143. In this embodiment, the housing 14 can be made of polycarbonate and acrylonitrile-butadiene-styrene copolymer together. As Figure 2 shown, in one embodiment, the groove 143 is an annular groove. The groove 143 is arranged around the edge of the window glass 10. The application does not limit the shape of the groove 143 of the housing 14, and it only needs to meet the actual application requirements.

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

[0061] The inner glass plate 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 plate 11. When the window glass 10 is installed on the vehicle body 300, the first surface 111 of the inner glass plate 11 faces the inside of the vehicle 1000, serving as the inner surface of the inner glass plate 11 and the inner glass surface of the window glass 10. The second surface 112 of the inner glass plate 11 faces away from the inside of the vehicle 1000, serving as the outer surface of the inner glass plate 11.

[0062] The outer glass plate 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 plate 12. When the window glass 10 is installed on the vehicle body 300, the fourth surface 122 of the outer glass plate 12 faces the outside of the vehicle 1000, serving as the outer surface of the outer glass plate 12 and the outer glass surface of the window glass 10. The third surface 121 of the outer glass plate 12 faces away from the outside of the vehicle 1000, serving as the inner surface of the outer glass plate 12.

[0063] The intermediate layer 13 is located between the third surface 121 of the outer glass plate 12 and the second surface 112 of the inner glass plate 11, and the intermediate layer 13 is connected to the third surface 121 of the outer glass plate 12 and the second surface 112 of the inner glass plate 11. The intermediate layer 13 is used to bond the outer glass plate 12 and the inner glass plate 11 together to form a laminated glass structure, improve the structural strength of the window glass 10, prevent the glass slag from splashing after the outer glass plate 12 and the inner glass plate 11 are broken and scratching the driver or passengers inside the vehicle 1000, and enable the window glass 10 to meet the safety standards and regulatory requirements in more scenarios.

[0064] The window glass 10 further 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 pattern shape. The light reflectance of the light extraction layer x is 8% to 12% (including the end point values 8% and 12%), and the light transmittance of the light extraction layer x is 80% to 90% (including the end point values 80% and 90%). When the light source 16 is not powered on, the pattern shape of the light extraction layer x is transparent, that is, the pattern shape is invisible. When the light source 16 is powered on, the light emitted by the light source 16 is incident on the light extraction layer x and undergoes diffuse reflection inside the inner glass plate 11. When the incident angle of the light is less than the angle of total internal reflection inside the inner glass plate 11, this part of the light exits from the first surface 111 of the inner glass plate 11, enabling the personnel inside the vehicle 1000 to see the pattern shape, thereby forming the lighting effect of the ambient light; when the incident angle of the light is greater than the angle of total internal reflection inside the inner glass plate 11, this part of the light continues to conduct inside the inner glass plate 11. The material used for the light extraction layer x is, for example, materials such as ink. For example, the light extraction layer x can be an ink coating, an ink printing layer, etc. This application does not make strict restrictions on this.

[0065] Such as Figure 3 And Figure 4As shown, the light guide member 15 is installed on the window glass 10. Along the width direction of the window assembly 100, the light guide member 15 is located on one side of the pattern shape of the light extraction layer x. Along the thickness direction of the window assembly 100, the light guide adhesive layer 17 is connected to the fifth surface 155 of the light guide member 15 and the first surface 111 of the inner glass plate 11 to fixedly connect the light guide member 15 to the window glass 10. The first surface 151 of the light guide member 15 faces and is spaced from the first surface 111 of the inner glass plate 11. The first surface 151 of the light guide member 15 extends away from the window glass 10. The shape of the light guide adhesive layer 17 is adapted to the shape of the inner glass surface of the window glass 10 and the shape of the fifth surface 155 of the light guide member 15. The size of the light guide adhesive layer 17 is adapted to the size of the fifth surface 155 of the light guide member 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] The circuit board 18 and the light source 16 are installed in the housing 14. The circuit board 18 and the light source 16 are both located in the groove 143 of the housing 14. The light source 16 is connected to the first assembly surface 181 of the circuit board 18. The second assembly surface 182 of the circuit board 18 faces the bottom surface of the groove 143, and the first bonding member 19 is connected to the second assembly surface 182 of the circuit board 18 and the bottom surface of the groove 143 to fixedly connect the circuit board 18 with the light source 16 installed thereon to the housing 14.

[0067] The housing 14 with the circuit board 18 and the light source 16 installed therein is installed on the window glass 10 with the light guide member 15 installed thereon. The first mounting surface 141 of the housing 14 faces the inner glass plate 11 of the window glass 10, and the second bonding member 20 is connected to the first mounting surface 141 of the housing 14 and the first surface 111 of the inner glass plate 11 to fixedly connect the housing 14 to the window glass 10. The notch of the groove 143 of the housing 14 faces the first surface 111 of the inner glass plate 11, and the groove 143 of the housing 14 and the window glass 10 enclose an accommodation space. The light guide member 15 is located in the accommodation space M. Along the thickness direction of the window assembly 100, the second surface 152 and the third surface 153 of the light guide member 15 both face the light source 16, and the second surface 152 and the third surface 153 are both spaced from the light source 16. Exemplarily, the distance from the second surface 152 and the third surface 153 to the light source 16 is greater than or equal to 1 mm and less than or equal to 2 mm, which not only ensures that the light guide member 15 will not touch the light source 16 and cause damage to the light source 16, but also ensures the quantity of light from the light source 16 entering the light guide member 15 and improves the light guiding rate of the light guide member 15 for light.

[0068] In this embodiment, the light guide member 15 is curved in an arc shape as a whole towards the direction of the window glass 10. That is, the first surface 151 and the fourth surface 154 of the light guide member 15 protrude towards the window glass 10. The thickness of the window assembly 100 is less than or equal to 20 mm to prevent the window assembly 100 from occupying too much space volume of the vehicle 1000.

[0069] As Figure 2 and Figure 3 shown, when the light source 16 is powered on, the light source 16 emits light in all directions. Taking the plane O - O passing through the center point of the light source 16 (i.e., the center point of the position 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 O - O is the first direction L, and the positive direction of the first direction L points to the central plane B - B of the width direction of the window glass 10 (the central plane B - B and Figure 1 the middle plane A - A are perpendicular to each other). The light emitted by the light source 16 forms an angle α with the plane O - O. When the angle formed by the light and the positive direction of the first direction L is an acute angle or a right angle, the angle α between the light and the plane O - O is 0° to 90° (including the end values 0° and 90°). When the angle formed by the light and the first direction L is an obtuse angle, the angle α between the light and the plane O - O is 0° to - 90° (including the end value - 90°). Exemplarily, as Figure 3 shown, the angle α between the light located on the right side of the plane O - O and the plane O - O is 0° to 90°, and the angle between the light located on the left side of the plane O - O and the plane O - O 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 O - O is a first angle α1, and the first angle α1 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 member 15 at an incident angle greater than the critical angle of the material of the light guide member 15. Specifically, the first light ray 161 enters the light guide member 15 through the second surface 152 of the light guide member 15. 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 towards the first surface 151 of the light guide member 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 towards the fifth surface 155 of the light guide member 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 light ray 161 on the inner glass plate 11 is 76.8°. The inclination angle β formed by the first light ray 161 converged by the first surface 151 and the first surface 111 of the inner glass plate 11 is smaller than the critical angle for total internal reflection of the first light ray 161 on the inner glass plate 11.

[0072] The included angle α between the second light ray 162 and the plane O - O is the second included angle α2, and the second included angle α2 is greater than or equal to 30° to 50°. The second light ray 162 is incident on the fifth surface 155 of the light guide member 15 at an incident angle greater than the critical angle of the material of the light guide member 15. Specifically, the second light ray 162 enters the light guide member 15 through the third surface 153 of the light guide member 15. 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 fifth surface 155 of the light guide member 15. The second light 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. Among them, the fourth surface 154 confines the boundary of the second light ray 162 conducted to the fifth surface 155 (blocks the second light ray 162 from exiting the light guide member 15 through the fourth surface 154), avoiding the loss of the light rays entering the light guide member 15 from the light source 16.

[0073] In this embodiment, both the first light ray 161 and the second light ray 162 are incident on the fifth surface 155 of the light guide member 15 at an incident angle greater than the critical angle of the material of the light guide member 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, and then oscillate and conduct between the second surface 112 and the first surface 111 of the inner glass plate 11 to make the pattern shape on the light extraction layer x emit light. Among them, a part 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 part of the light ray reflected by the light extraction layer x continues to oscillate and conduct between the second surface 112 and the first surface 111 of the inner glass plate 11 to conduct the light ray to the pattern shape on the light extraction layer x far from the light guide member 15. Another part 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 part of the light ray scattered by the light extraction layer x exits at an angle smaller than the critical angle of the material of the inner glass plate 11, forming a glowing pattern to be observed by the people inside the vehicle 1000.

[0074] It should be noted that, for the convenience of distinguishing the light rays in the light guide member 15 and the window glass 10, the light rays emitted by the light source 16 and entering the light guide member 15 are divided into the first light ray 161 and the second light ray 162. The first light ray 161 and the second light ray 162 respectively represent a beam of light rays. In fact, there is more than one beam of light entering the light guide member 15. Therefore Figure 3The solid arrows in the figure are used to represent, representatively, the light rays of the first light ray 161 and the second light ray 162 entering the window glass 10 through the light guide member 15 and the light guide adhesive layer 17, and do not represent all the light rays of the light guide member 15 and the window glass 10 under actual conditions.

[0075] In this embodiment, the refractive indices of the inner glass plate 11, the light guide member 15, and the light guide adhesive layer 17 of the window glass 10 for light are close. The difference in the refractive indices of the inner glass plate 11 and the light guide adhesive layer 17 for light is less than 0.02. More preferably, the difference in the refractive indices of the inner glass plate 11 and the light guide adhesive layer 17 for light is less than 0.01. The difference in the refractive indices of the light guide adhesive layer 17 and the light guide member 15 for light is less than 0.02. More preferably, the difference in the refractive indices of the light guide adhesive layer 17 and the light guide member 15 for light is less than 0.01, so as to ensure that the light rays greater than the critical angle of the material of the light guide member 15 can be incident on the fifth surface 155 of the light guide member 15 and enter the inner glass plate 11 through the light guide adhesive layer 17, improving the utilization rate of light rays and reducing the loss of light rays passing through the light guide member 15 and the light guide adhesive layer 17. Exemplarily, the refractive indices of the window glass 10, the light guide member 15, and the light guide adhesive layer 17 for light are all 1.52.

[0076] In the related art, the arrangement of the light guide structure and the atmosphere lamp and the structural design of the light guide structure result in only a small part of the light rays emitted by the atmosphere lamp entering the sunroof glass through the light guide structure, and the light guide efficiency of the light guide structure is low. For example, the atmosphere lamp is located on the side in the width direction of the light guide structure, and the light rays emitted by the atmosphere lamp are incident from the side of the light guide structure and then enter the sunroof glass. Through simulation tests, the effective output light intensity of the light guide structure for the light rays of the atmosphere lamp is about 0.116777 cd. A large part of the light rays emitted by the atmosphere lamp still cannot be conducted to the sunroof glass, resulting in a low brightness of the illuminated pattern and being almost invisible during the day, affecting the use of the atmosphere lamp.

[0077] In the embodiment of the present application, the light guide member 15 and the light source 16 are arranged opposite to and spaced apart from each other along the thickness direction of the window assembly 100. The light source 16 emits light rays, and most of the light rays enter the window glass 10 through the light guide member 15. Among them, the first light ray 161 enters the inner glass plate 11 of the window glass 10 after two convergences on the second surface 152 and the first surface 151 of the light guide member 15, and the second light ray 162 enters the inner glass plate 11 of the window glass 10 after one convergence on the third surface 153 of the light guide member 15. Through simulation tests, the effective output light intensity of the light guide member 15 for the light rays of the light source 16 is about 0.185482 cd. Compared with the effective output light intensity of the light guide structure for the light rays of the atmosphere lamp in the prior art, the effective output light intensity of the light guide member 15 for the light rays of the light source 16 is increased by at least 2.54 times, greatly improving the utilization rate of the light rays emitted by the light source 16 by the light guide member 15, and thus greatly improving the brightness of the illuminated pattern.

[0078] Please refer to Figure 5 , Figure 5 which Figure 2 is a partial cross-sectional schematic view of the second embodiment of the window assembly shown in the figure.

[0079] In this embodiment, different from the structure of the window assembly 100 of the first embodiment above, the structure of the light guide member 15 of the window assembly 100 in this embodiment is different from the structure of the light guide member 15 in the first embodiment above. The light guide member 15 in this embodiment includes a first light guide member 15a and a second light guide member 15b. The second light guide member 15b is laminated and connected to the window glass 10 through a light guide adhesive layer 17. The first light guide member 15a and the light source 16 are both disposed on the circuit board 18, and the first light guide member 15a and the light source 16 are opposite and spaced apart along the thickness direction of the window assembly 100. The first light guide member 15a and the second light guide member 15b are opposite 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 member 15a, is reflected and converged by the first light guide member 15a and then exits, and then sequentially enters the second light guide member 15b, the light guide adhesive layer 17 connected to the second light guide member 15b, and the inner glass plate 11 of the window glass 10.

[0080] In this embodiment, the first light guide member 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 opposite surface 158a connected in sequence. The sixth surface 156 is connected to the first surface 151 and the second surface 152, and is disposed at an angle to the first surface 151 and the second surface 152. The sixth surface 156 and the second surface 152 of the first light guide member 15a and the third surface 153 are all located on the same side in the width direction of the first light guide member 15a, and are all disposed opposite to the first opposite surface 158a along the width direction of the first light guide member 15a. The first opposite 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 member 15a is made of plastic. The sixth surface 156 and the first opposite surface 158a are both flat surfaces. The arc bending directions of the first surface 151 and the fourth surface 154 are substantially the same. The first surface 151 protrudes outward in the thickness direction of the first light guide member 15a, and the fourth surface 154 is concave inward in the thickness direction of the first light guide member 15a. The second surface 152 and the third surface 153 are both convex arc surfaces in the width direction of the first light guide member 15a, and the protruding directions of the second surface 152 and the third surface 153 intersect. An angle is formed at the connection position of the second surface 152 and the third surface 153.

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

[0083] It can be understood that the light guide member 15 in this embodiment is split into a first light guide member 15a and a second light guide member 15b. Compared with the light guide member 15 in the first embodiment above, the light guide member 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 opposite surface 158a, a second opposite surface 158b and a light guide surface 159. Along the thickness direction of the light guide member 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 light guide member 15 in the thickness direction. The light guide surface 159 is spaced apart from the fourth surface 154, and the light guide surface 159 and the fourth surface 154 are located on the other side of the light guide member 15 in the thickness direction. 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 member 15. The end surface 157 is connected to the fifth surface 155 and the light guide surface 159.

[0084] As Figure 5 shown, the second light guide member 15b is installed on the vehicle window glass 10. The fifth surface 155 of the second light guide member 15b faces the inner glass plate 11 of the vehicle window glass 10. The light guide adhesive layer 17 is connected to the fifth surface 155 of the second light guide member 15b and the first surface 111 of the inner glass plate 11 to fixedly connect the second light guide member 15b to the vehicle window glass 10. The shape of the light guide adhesive layer 17 is adapted to the shape of the fifth surface 155 of the second light guide member 15b and the shape of the first surface 111 of the inner glass plate 11. The size of the light guide adhesive layer 17 is adapted to the size of the second light guide member 15b. Exemplarily, the thickness of the second light guide member 15b is 2.1 mm. The thickness of the light guide adhesive layer 17 is 1.5 mm.

[0085] The circuit board 18, the light source 16, and the first light guide member 15a are all installed in the housing 14. The circuit board 18, the light source 16, and the first light guide member 15a are all located in the groove 143 of the housing 14. The light source 16 and the first light guide member 15a are both connected to the circuit board 18. For example, the light source 16 is adhered to the first assembly surface 181 of the circuit board 18 by gluing. The second surface 152, the third surface 153, and the sixth surface 156 of the first light guide member 15a all face the first assembly surface 181 of the circuit board 18, and the second surface 152 and the third surface 153 are both spaced apart from the light source 16. A rivet or a riveting post (not shown in the figure) protrudes from the sixth surface 156 of the first light guide member 15a, so that the first light guide member 15a can be fixedly connected to the circuit board 18 by hot riveting. The second assembly surface 182 of the circuit board 18 faces the bottom surface of the groove 143, and the first bonding member 19 is connected to the second assembly surface 182 of the circuit board 18 and the bottom surface of the groove 143 to fixedly connect the circuit board 18 equipped with the first light guide member 15a and the light source 16 to the housing 14.

[0086] The housing 14 equipped with the circuit board 18, the light source 16, and the first light guide member 15a is installed on the vehicle window glass 10 equipped with the second light guide member 15b. The first mounting surface 141 of the housing 14 faces the inner glass plate 11 of the vehicle window glass 10, and the second bonding member 20 is connected to the first mounting surface 141 of the housing 14 and the first surface 111 of the inner glass plate 11 to fixedly connect the housing 14 to the vehicle window glass 10. The second light guide member 15b is located in the groove 143 of the housing 14. The first opposite surface 158a of the first light guide member 15a and the second opposite surface 158b of the second light guide member 15b are opposite and spaced apart along the width direction of the vehicle window assembly 100. The first surface 151 of the first light guide member 15a faces the first surface 111 of the inner glass plate 11 and is opposite and spaced apart from the first surface 111.

[0087] As Figure 5 shown, when the light source 16 is powered on, the light source 16 emits light in all directions. Among them, the first light ray 161 enters the first light guide member 15a 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 first light guide member 15a. 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 first opposite surface 158a of the first light guide member 15a. The first light ray 161 conducted to the first opposite surface 158a exits through the first opposite surface 158a and enters the second light guide member 15b through the second opposite surface 158b of the second light guide member 15b. The first light ray 161 entering the second light guide member 15b enters the first surface 111 of the inner glass plate 11 through the fifth surface 155 of the second light guide member 15b and the light guide adhesive layer 17.

[0088] The second light ray 162 enters the first light guide 15a through the third surface 153 of the first light guide 15a. 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 towards the first opposite surface 158a of the first light guide 15a. The second light ray 162 conducted to the first opposite surface 158a exits through the first opposite surface 158a and enters the second light guide 15b through the second opposite surface 158b of the second light guide 15b. The second light ray 162 entering the second light guide 15b enters the first surface 111 of the inner glass plate 11 through the fifth surface 155 of the second light guide 15b and the light guide adhesive layer 17. Among them, the fourth surface 154 defines the boundary of the second light ray 162 converging to the first opposite surface 158a to prevent the second light ray 162 from exiting the first light guide 15a through the fourth surface 154, avoiding the loss of the light rays entering the first light guide 15a from the light source 16.

[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 window glass 10 are close to each other. The difference in refractive index between the inner glass plate 11 and the light guide adhesive layer 17 is less than 0.02. More preferably, the difference in refractive index between the inner glass plate 11 and the light guide adhesive layer 17 is less than 0.01. The difference in refractive index between the light guide adhesive layer 17 and the second light guide 15b is less than 0.02. More preferably, the difference in refractive index between the light guide adhesive layer 17 and the second light guide 15b is less than 0.01, so as to ensure that the light rays with an angle greater than the critical angle of the material 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 through the light guide adhesive layer 17, improving the utilization rate of light rays and reducing the loss of light rays passing through the second light guide 15b and the light guide adhesive layer 17. In addition, in this embodiment, the same structures, effects, and processes as those in the above first embodiment are not described herein again.

[0090] In some embodiments, different from the structures of the window assemblies 100 in the first and second embodiments above, the window glass 10 in this embodiment may also be a single-layer glass structure. The window glass 10 includes a glass plate. The glass plate includes an inner glass surface and an outer glass surface, and the inner glass surface and the outer glass surface are arranged opposite to each other along the thickness direction of the glass plate. The light guide adhesive layer 17 is connected to the fifth surface 155 of the light guide member 15 and the inner glass surface of the glass plate. The first light ray 161 and the second light ray 162 are emitted from the fifth surface 155 of the light guide member 15 and then enter the inner glass surface through the light guide adhesive layer 17 and are conducted within the glass plate. Among them, the refractive indices of the light guide adhesive layer 17, the glass plate, and the light guide member 15 for light are close. The difference in the refractive indices of the light guide adhesive layer 17 and the glass plate for light is less than 0.02. More preferably, the difference in the refractive indices of the glass plate and the light guide adhesive layer 17 for light is less than 0.01. The difference in the refractive indices of the light guide adhesive layer 17 and the light guide member 15 for light is less than 0.02. More preferably, the difference in the refractive indices of the light guide adhesive layer 17 and the light guide member 15 for light is less than 0.01, so as to ensure that light rays greater than the critical angle of the material of the light guide member 15 can be incident on the fifth surface 155 of the light guide member 15 and enter the glass plate through the light guide adhesive layer 17, improve the utilization rate of light, and reduce the loss of light passing through the light guide member 15 and the light guide adhesive layer 17.

Specific examples are used herein to elaborate on the principles and implementation manners of the present application. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manners and application scopes.
