Technical Field
[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a glass assembly and a vehicle. Background Technology
[0002] With the continuous innovation of automotive technology and the increasing demands of users, the functions of automotive glass used in vehicles are becoming increasingly diverse. For example, light-emitting elements are integrated into the glass to give it a light-emitting function, thereby creating a better lighting effect and environment inside the vehicle and improving the comfort and enjoyment of passengers.
[0003] In traditional technology, light-emitting components typically include multiple LEDs spaced apart and light guide strips positioned opposite each LED. This allows light emitted from the LEDs to enter the incident surface of the light guide strip and, through refraction, enter the glass, thereby improving the glass's luminous effect. However, uneven brightness can occur on the exit surface of the light guide strip along its length, affecting aesthetics and reducing the user experience. Summary of the Invention

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0045] Traditional light-emitting components typically include multiple LEDs spaced apart and a light guide strip positioned opposite each LED. This allows light emitted from the LEDs to enter the incident surface of the light guide strip and, through refraction, into the glass. However, uneven brightness occurs on the exit surface of the light guide strip along its length, affecting aesthetics and reducing user experience. This application provides a glass assembly and vehicle that effectively mitigates the uneven brightness on the exit surface of the light guide strip along its length, improving aesthetics and user experience, and facilitating application and promotion.
[0046] For details, please refer to Figure 1 and Figure 2 One embodiment of this application provides a glass assembly 10, which may include a glass component 100, a light guide strip 200, and a light-emitting component 300. The light guide strip 200 is connected to the glass component 100. Optionally, the light-emitting component 300 described above may be applied to, but is not limited to, ambient lighting in vehicles, thereby improving the lighting atmosphere and user experience of the vehicle.
[0047] Combination Figure 1 and Figure 2 As shown, the light guide strip 200 has an incident surface 200a and an exit surface 200b that are disposed opposite to each other. The incident surface 200a has a plurality of recesses a1 arranged along the length Y direction of the light guide strip 200. The light-emitting component 300 is connected to the glass component 100, and the light-emitting component 300 includes light-emitting elements 310 that are spaced apart along the length Y direction of the light guide strip 200, with one light-emitting element 310 disposed opposite to one recess a1.
[0048] The glass assembly 10 described above has multiple recesses a1 arranged along the length Y direction of the light guide strip 200 on the incident surface 200a. A light-emitting body 310 is disposed opposite to a recess a1, so that the incident light x of the light-emitting body 310 can be diffused through the recess a1. This improves the brightness uniformity of the emitted light, reduces the appearance of uneven brightness or alternating light and dark on the light-emitting component 300, and improves the aesthetics and user experience.
[0049] It should be noted that, as Figure 1As shown, the light source 310 includes at least an incident light ray x that directly enters the glass assembly 100 from the part where the light guide strip 200 abuts against the glass assembly 100, and an incident light ray x that enters from the incident surface 200a, exits from the exit surface 200b, and re-enters the glass assembly 100 after being propagated through the air. If the brightness of the light emitted on the exit surface 200b is uneven, there may be alternating bright and dark areas on the appearance of the light source 300, which will affect the user's viewing experience.
[0050] Therefore, it is worth noting that by applying the above solution, the brightness uniformity of the emitted light from the emitting surface 200b can be improved, avoiding uneven light brightness or alternating light and dark along the length Y of the light guide strip 200, thus improving the user's viewing experience when looking at the aforementioned light-emitting component 300 from inside the vehicle.
[0051] See also the following in this application: Figure 1 The glass assembly 100 can be specifically a laminated glass, that is, it is composed of at least an inner glass 110, an intermediate interlayer 120 and an outer glass 130 assembled in a stacked manner.
[0052] Optionally, the outer glass 130 and the inner glass 110 can be any type of single-pane glass, double-pane glass, etc., and can be flexibly selected according to actual needs.
[0053] The intermediate layer 120 can be, but is not limited to, PVB (Polyvinyl Butyral). PVB is a product of the condensation of polyvinyl alcohol and butyraldehyde under acid catalysis. Due to the long branched chains in the PVB molecule, it has good flexibility, a low glass transition temperature, and high tensile strength and impact strength. PVB has excellent transparency, good solubility, and good resistance to light, water, heat, cold, and film formation. Its functional groups can undergo various reactions such as acetyl saponification, hydroxyl esterification, and sulfonation, and it has high adhesion to materials such as glass and metals (especially aluminum).
[0054] Preferably, see Figure 1 The intermediate interlayer 120 may also be provided with a pattern structure 121. The light from the light source 310 can be projected onto the pattern structure 121 through the refraction of the intermediate interlayer 120, thus making the glass display different pattern light-emitting effects and improving the user experience.
[0055] Optionally, continue reading Figure 1The light-emitting component 300 may further include a cover 320, a circuit board 330, and an electronic component assembly 340. The light-emitting element 310 is electrically connected to the circuit board 330. The circuit board 330 is connected to one of the glass component 100, the cover 320, or the light guide strip 200. The electronic component assembly 340 is connected to the cover 320, which is used to connect to the glass component 100 and cover the light guide strip 200.
[0056] Specifically, such as Figure 1 As shown, the circuit board 330 can be pre-connected to the side of the light guide strip 200 away from the glass assembly 100. The light emitters 310 are disposed near the edge of the circuit board 330, such that each light emitter 310 is arranged to maintain a state in which a light emitter 310 is opposite to a recess a1.
[0057] Of course, the circuit board 330 can also be connected to the cover 320. When the cover 320 covers the light guide strip 200, the precise positioning connection between the cover 320 and the glass assembly 100 enables a light emitter 310 to automatically align and be set relative to a recessed portion a1.
[0058] Understandably, the cover 320 and the glass assembly 100 may be provided with corresponding positioning structures (not shown) to maintain the precise positioning connection between the cover 320 and the glass assembly 100, so that the relative position of a light-emitting element 310 and a recess a1 can be automatically and precisely positioned.
[0059] Additionally, see Figure 3 The circuit board 330 can also be directly connected to the glass assembly 100, and the connection position of the circuit board 330 on the glass assembly 100 can be adjusted to ensure that a light-emitting element 310 is positioned opposite to a recess a1.
[0060] Users can choose any of the above connection methods for the 330 circuit board according to their actual needs.
[0061] Optionally, the aforementioned electronic component 340 may include, but is not limited to, at least a controller, a communicator, or a sensor to confirm the normal operation of the light emitter 310, which will not be elaborated here.
[0062] Optionally, see Figure 1 and Figure 3 The glass assembly 10 may also include a light-shielding structure 400, which is disposed at the connection between the cover 320 and the glass assembly 100, thereby improving the light utilization rate of the light-emitting body 310 and preventing light leakage.
[0063] Optionally, the light-shielding structure 400 may be implemented as black ink, etc.
[0064] Optionally, please refer to Figure 4 The incident surface 200a can be set at a preset angle with the direction perpendicular to the glass assembly 100 so that the incident surface 200a is offset from the light source 310. This can improve the capture rate of the incident light x of the light source 310 by the incident surface 200a and reduce the reflection loss of the incident light x.
[0065] Understandably, combined Figure 1 As shown, the incident light x needs to be refracted at a certain angle through the light guide strip 200 to enter the glass assembly 100. Therefore, the incident surface 200a is set to be offset from the light source 310 in the direction closer to the glass assembly 100. This can optimize the angle of the incident surface 200a facing the incident light x and improve the capture rate of the incident light x of the light source 310 by the incident surface 200a.
[0066] Preferably, please combine Figure 5 and Figure 6 As shown, the incident surface 200a is arranged in the form of an arc a2 on the cross section of the light guide strip 200 in the width direction X. This can further optimize the angle of the incident surface 200a facing the incident light x and improve the capture rate of the incident light x of the light source 310 by the incident surface 200a.
[0067] It should be noted that, as Figure 6 As shown, the incident light ray x of the light source 310 can be distributed in a roughly divergent pattern from the center outwards. Setting the incident surface 200a in the shape of a guide arc a2 helps to improve the compatibility between the incident surface 200a and the incident light ray x in a divergent pattern.
[0068] Optionally, see Figure 7 The light-emitting body 310 and the concave portion a1 have a distance L. The light-emitting body 310 has a first projection width d1 on the incident surface 200a. The distance L is configured such that the first projection width d1 falls completely within the width setting range d3 of the concave portion, thus ensuring that the light can be completely captured and avoiding light leakage.
[0069] It should be noted that, as Figure 7 As shown, the aforementioned first projection width d1 refers to the width range of the light from the light source 310 hitting the incident surface 200a along the length direction Y of the light guide strip 200.
[0070] Understandably, the first projection width d1 increases as the spacing L increases and decreases as the spacing L decreases. In this embodiment, by configuring the spacing L such that the first projection width d1 falls entirely within the width setting range d3 of the recess, it helps to ensure that the incident light x of the light source 310 can completely pass through the recess a1 to form the first divergence, thereby improving the light divergence effect and thus improving the brightness uniformity of the emitted light.
[0071] Optionally, the surface of the recessed portion a1 can be a concave arc surface. It should be noted that, as... Figure 2 As shown, the concave direction of the aforementioned concave arc surface refers to the direction in which the incident surface 200a is away from the light-emitting body 310.
[0072] Preferably, the light-emitting body 310 is opposite to the deepest position F of the concave portion a1. This helps to improve the light-diffusing effect of the concave portion a1 on the light-emitting body 310, and also helps to improve the consistency of the light divergence from the deepest position F of the concave surface to both sides, thereby improving aesthetics. It should be noted that the deepest position F of the concave portion a1, as a recessed structure, is the position farthest from the light-emitting body 310 in the width direction X of the light guide strip 200. At this position, the tangent of the concave surface is perpendicular to the width direction X of the light guide strip 200.
[0073] More preferably, the radius of curvature of the concave surface gradually increases from the deepest position F in the direction extending to both sides, which helps to further improve the brightness uniformity of the light emitted by the light source 310 when it exits the emission surface 200b.
[0074] Specifically, in this embodiment, the radius of curvature of the concave surface is set to be minimum at the deepest position F. This helps to accelerate the divergence speed of light near the deepest position F of the concave surface. Since the light emitter 310 is arranged directly opposite the deepest position F of the concave surface, most of the light emitted by the light emitter 310 is concentrated near the deepest position F, thereby enabling the divergence of most of the light. Conversely, the radius of curvature of the concave surface is gradually increased from the deepest position F towards both sides. This allows the divergence speed of the incident light ray x along the direction extending from the deepest position F towards both sides to gradually decrease. That is, the relatively weaker light rays that are farther away from the deepest position F can maintain their original direction or diverge at a relatively slower speed, thereby improving the consistency of light brightness in the overall effect.
[0075] In some embodiments, combined with Figure 7 As shown, the radius of curvature of the concave arc surface at the farthest point on both sides of the deepest position F is R1, and the included angle between the centers of the circles at these two positions is the wrap angle α.
[0076] Optionally, the light-emitting body 310 has a light-emitting angle β. When the spacing L is configured to satisfy different conditions with R1, it is only necessary to configure α and β to satisfy a certain size relationship so that the aforementioned first projection width d1 can completely fall within the width setting range d3 of the concave portion.
[0077] Specifically, the spacing L and R1 can be configured such that when L is greater than R1, α is greater than β; when L is less than R1, α is less than or equal to β. Understandably, when L is greater than R1, in other words, when the light emitter 310 is positioned at a relatively large distance from the concave portion a1, α must be greater than β to ensure that the first projection width d1 falls completely within the width setting range d3 of the concave portion, thus capturing all incident light rays x. When L is less than R1, α is allowed to be less than or equal to β, which similarly ensures that the first projection width d1 falls completely within the width setting range d3 of the concave portion, thus capturing all incident light rays x. Users only need to design according to this relationship, improving the simplicity of the design.
[0078] Optionally, continue reading Figure 7 There is a distance d between the deepest position F of the concave surface of two adjacent concave portions a1. The light of the light source 310 has a second projection width d2 inside the light guide strip 200. The distance d is configured such that at least part of the second projection width d2 of the two adjacent light sources 310 overlaps with each other. This ensures that the emitted light can completely cover and emit out of the emission surface 200b, avoiding uneven brightness and alternating light and dark on the emission surface 200b, which helps to improve the aesthetics.
[0079] Optionally, the surfaces of two adjacent recesses a1 are smoothly joined; or, the incident surface 200a includes a spaced transition portion a3, through which the surfaces of two adjacent recesses a1 are smoothly joined.
[0080] Understandably, the first projection width d1 of the light emitter 310 on the incident surface 200a only needs to fall completely within the width setting range d3 of the concave portion. Therefore, adjacent concave portions a1 can be set to be directly and smoothly joined or smoothly joined through the first transition portion a3. This helps to avoid sharp corners at the joining position, making the propagation of light more stable and avoiding sudden changes in light.
[0081] In this embodiment, the recesses a1 are arranged at intervals and smoothly joined to the surfaces of the two adjacent recesses a1 by a transition portion a3. Of course, the transition portion a3 does not have the function of capturing the incident light ray x, and the transition portion a3 can be set as a plane.
[0082] In one embodiment, the transition portion a3 may be coated with a reflective material, which can reduce light escape and improve light utilization and luminous effect.
[0083] Alternatively, the reflective material may be, but is not limited to, white ink, transparent ink, or a metallic coating.
[0084] Alternatively, in some embodiments, the reflective material can be formulated according to the formula Select the appropriate model. Here, η is the light absorption efficiency; k is the material absorption coefficient; Iout is the output light intensity, which is the light intensity emitted from the light guide strip 200 after propagation; Iin is the input light intensity, which is the original light intensity emitted from the light source 310, expressed in luminous flux (e.g., lumen) or optical power (e.g., watt).
[0085] Optionally, please refer to Figure 2 The emitting surface 200b has a plurality of outward protrusions b1 arranged along the length direction Y of the light guide strip 200, and each concave portion a1 and each outward protrusion b1 are arranged opposite to each other in the width direction X of the light guide strip 200.
[0086] In this embodiment, the glass assembly 10 first has a plurality of recessed portions a1 arranged along the length Y of the light guide strip 200 on the incident surface 200a, and a light emitter 310 is disposed opposite to a recessed portion a1, so that the incident light x of the light emitter 310 can form a first divergence through the recessed portion a1. In addition, the exit surface 200b has a plurality of protruding portions b1 arranged along the length Y of the light guide strip 200, and each recessed portion a1 and each protruding portion b1 are disposed opposite to each other in the width X of the light guide strip 200, so that the emitted light of the light emitter 310 can form a second divergence through the protruding portion b1. This improves the brightness uniformity of the emitted light, reduces the appearance of uneven brightness or alternating light and dark in the light-emitting component 300, and improves the aesthetics and user experience.
[0087] Optionally, the surface of the protruding portion b1 is convex. It should be noted that the protruding direction of the protruding portion b1 is the direction away from the light-emitting body 310 from the emission surface 200b.
[0088] Optionally, see Figure 8 The light guide strip 200 may include a first light guide portion 210 and a second light guide portion 220. The second light guide portion 220 is configured to cover at least a portion of the first light guide portion 210, and the incident surface 200a and the exit surface 200b are respectively disposed on both sides of the second light guide portion 220 in the width direction X, which helps to reduce the difficulty of setting the light guide strip 200.
[0089] Optionally, in some other embodiments, the glass assembly 10 includes a light-transmitting medium 250, and the light guide strip 200 may include a first light guide portion 210, a third light guide portion 230, and a fourth light guide portion 240. The third light guide portion 230 and the fourth light guide portion 240 are respectively connected to both sides of the first light guide portion 210 in the width direction X. The incident surface 200a is disposed on the side surface of the third light guide portion 230 away from the first light guide portion 210, and the exit surface 200b is disposed on the side surface of the fourth light guide portion 240 away from the first light guide portion 210. The light-transmitting medium 250 is bonded between the light guide strip 200 and the glass assembly 100, thus realizing the separate arrangement of the third light guide portion 230 and the fourth light guide portion 240, which helps to reduce the difficulty of setting the light guide strip 200.
[0090] Optionally, in some other embodiments, the light guide strip 200 may further include a first intermediate medium 260 and a second intermediate medium 270, wherein the first intermediate medium 260 is bonded between the third light guide portion 230 and the first light guide portion 210, and the second intermediate medium 270 is bonded between the fourth light guide portion 240 and the first light guide portion 210, which helps to improve the connection stability between the third light guide portion 230 and the first light guide portion 210, and between the fourth light guide portion 240 and the first light guide portion 210.
[0091] Optionally, the aforementioned light-transmitting medium 250, the first intermediate medium 260 and the second intermediate medium 270 may be, but are not limited to, optical adhesives to ensure light transmittance.
[0092] Alternatively, users can choose any of the above settings for the light guide strip 200 according to their actual needs.
[0093] Based on the glass assembly 10 described above in this application, this application also provides an embodiment of a feasible light guide strip 200 for the glass assembly 10 as a reference. Specifically, the parameters of the light guide strip 200 are as follows:
[0094] The incident surface 200a has a radius of curvature R1: R1 = 20 mm.
[0095] The emission angle β of the luminescent body 310 is β=120°.
[0096] Enclosure angle α: α = 150°.
[0097] According to the relationship The spacing between adjacent light emitters 310 In practice, d=35 mm can be selected.
[0098] According to the relationship The distance between the light-emitting body 310 and the concave portion a1: (L≤R1 must be satisfied).
[0099] It is worth noting that, please refer to Figure 7 According to the relationship The angle of incidence can also be adjusted: (This can be corrected to a practically feasible angle). It should be noted that, according to Fresnel's law of reflection, reflection loss is minimized when the light ray is incident perpendicularly (θ=0). Therefore, reducing the deviation angle θ between the incident ray x and the normal to the incident surface 200a can reduce the reflection loss of the incident ray x and improve its utilization rate.
[0100] According to another aspect of this application, this application provides a vehicle that may include the glass assembly 10 described above.
[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0102] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
