[0045] Considering that conventional light-emitting assemblies generally include multiple lamp beads spaced apart and light guide strips positioned opposite each lamp bead, so that light emitted by the lamp beads enters the incident surface of the light guide strip and is refracted by the light guide strip into the glass, uneven brightness may occur on the exit surface of the light guide strip along its length, thereby affecting aesthetics and reducing user experience. The present application provides a glass assembly and vehicle that can effectively mitigate the uneven brightness on the exit surface of the light guide strip along its length, improve aesthetics and user experience, and facilitate application and promotion.

[0046] Specifically, please refer to Figure 1 and Figure 2 One embodiment of the present application provides a glass assembly 10, which may include a glass component 100, a light guide bar 200, and a light-emitting component 300. The light guide bar 200 is connected to the glass component 100. Optionally, the light-emitting component 300 described herein may be, but is not limited to, applied to a vehicle's ambient lighting, thereby enhancing the vehicle's lighting atmosphere and user experience.

[0047] Combine Figure 1 and Figure 2 As shown, the light guide bar 200 has an incident surface 200a and an exit surface 200b, which are disposed opposite each other. The incident surface 200a has a plurality of recessed portions a1 arranged along the length direction Y of the light guide bar 200. The light-emitting assembly 300 is connected to the glass assembly 100 and includes light-emitting bodies 310 spaced apart along the length direction Y of the light guide bar 200, with each light-emitting body 310 disposed opposite a recessed portion a1.

[0048] The above-mentioned glass assembly 10 has a plurality of recessed portions a1 arranged along the length direction Y of the light guide strip 200 through the incident surface 200a, and a light-emitting body 310 is arranged opposite to a recessed portion a1, so that the incident light x of the light-emitting body 310 can be diverged through the recessed portion a1, thereby improving the brightness uniformity of the emitted light, reducing the uneven brightness or alternating light and dark in the appearance of the light-emitting component 300, and improving the aesthetics and user experience.

[0049] It should be noted that if Figure 1As shown, the light emitting body 310 includes at least the incident light x that directly enters the glass component 100 from the abutment portion of the light guide bar 200 and the glass component 100, and the incident light x that enters from the incident surface 200a, exits from the exit surface 200b, and enters the glass component 100 again through the air. In this way, if the brightness of the light emitted on the exit surface 200b is uneven, the appearance of the light emitting component 300 may appear alternating between light and dark, affecting the user's perception.

[0050] Therefore, it is worth noting that the application of the above-mentioned solution in this application can improve the brightness uniformity of the light emitted from the exit surface 200b, avoid uneven light brightness or alternating light and dark along the length direction Y of the light guide bar 200, and improve the user's viewing experience when looking at the aforementioned light-emitting component 300 in the car.

[0051] In this application, continue to refer to Figure 1 The glass assembly 100 may be specifically a laminated glass, that is, composed of at least an inner layer of glass 110, an intermediate layer 120 and an outer layer of glass 130 in a stacked assembly manner.

[0052] Optionally, the outer glass 130 and the inner glass 110 can be any one of single-layer glass, double-layer glass, etc., and can be flexibly selected according to actual needs.

[0053] Interlayer 120 can be, but is not limited to, PVB (Polyvinyl Butyral). PVB is a product of the acid-catalyzed condensation of polyvinyl alcohol and butyraldehyde. Because PVB molecules contain long side chains, they exhibit excellent flexibility, a low glass transition temperature, and high tensile strength and impact resistance. PVB also offers excellent transparency, solubility, and excellent light, water, heat, and cold resistance, as well as film-forming properties. Its functional groups can undergo various reactions, including saponification of acetyl groups, esterification of hydroxyl groups, and sulfonation, resulting in strong adhesion to materials such as glass and metals (particularly aluminum).

[0054] Preferably, see Figure 1 The middle interlayer 120 may also be provided with a pattern structure 121. The light from the light emitting body 310 can be projected onto the pattern structure 121 through the refraction of the middle interlayer 120. This makes the glass show different pattern luminous effects, thereby improving the user experience.

[0055] Optionally, continue to Figure 1The light-emitting assembly 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 assembly 100, the cover 320, or the light guide bar 200. The electronic component assembly 340 is connected to the cover 320. The cover 320 is used to connect to the glass assembly 100 and cover the light guide bar 200.

[0056] Specifically, if Figure 1 As shown, the circuit board 330 can be partially pre-connected to the side of the light guide bar 200 facing away from the glass assembly 100. The light emitters 310 are arranged near the edge of the circuit board 330 so that each light emitter 310 is arranged to maintain a light emitter 310 relative to an inner recess a1.

[0057] Of course, the circuit board 330 can also be connected to the cover 320. When the cover 320 is covered on the light guide bar 200, the precise positioning connection between the cover 320 and the glass assembly 100 can automatically align and position a light emitting body 310 with an inner recess a1.

[0058] It is understandable that 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 body 310 and an inner recess a1 can be automatically and accurately positioned.

[0059] Also, see Figure 3 The circuit board 330 can also be directly connected to the glass component 100, and the connection position of the circuit board 330 on the glass component 100 can be adjusted to ensure that a light-emitting body 310 is arranged opposite to an inner recess a1.

[0060] The user can select any one of the above connection methods of the circuit board 330 according to actual needs.

[0061] Optionally, the aforementioned electronic component assembly 340 may include, but is not limited to, at least a controller, a communicator or a sensor, etc., to confirm the normal operation of the light-emitting body 310, which will not be elaborated here.

[0062] Optionally, see Figure 1 and Figure 3 The glass assembly 10 may further include a shading structure 400 , which is disposed at the connection portion between the cover 320 and the glass assembly 100 , thereby improving the light utilization rate of the light emitting body 310 and preventing light from overflowing.

[0063] Optionally, the light shielding structure 400 may be implemented as, but not limited to, black ink or the like.

[0064] Optionally, see Figure 4 The incident surface 200a can be set at a preset angle to the direction perpendicular to the glass component 100, so that the incident surface 200a deviates from the light emitting body 310. This can improve the capture rate of the incident surface 200a for the incident light x of the light emitting body 310 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 by the light guide bar 200 to enter the glass component 100. Therefore, the incident surface 200a is set away from the light emitting body 310 in a direction close to the glass component 100. In this way, the angle of the incident surface 200a facing the incident light x can be optimized, thereby improving the capture rate of the incident surface 200a for the incident light x of the light emitting body 310.

[0066] Preferably, combine Figure 5 and Figure 6 As shown, the incident surface 200a is arranged as a guide arc a2 on the cross section of the width direction X of the light guide bar 200, so that the angle of the incident surface 200a facing the incident light x can be further optimized, thereby improving the capture rate of the incident surface 200a for the incident light x of the light emitting body 310.

[0067] It should be noted that if Figure 6 As shown, the incident light x of the light emitting body 310 can be roughly distributed in a divergent manner from the center to the surroundings. Setting the incident surface 200a in a guide arc a2 helps to improve the adaptability of the incident surface 200a to the divergent distribution of the incident light x.

[0068] Optionally, see Figure 7 The light emitting body 310 has a distance L with the inner concave portion a1, and the light emitting body 310 has a first projection width d1 on the incident surface 200a. The distance L is configured so that the first projection width d1 completely falls within the width setting range d3 of the inner concave portion, thereby ensuring that the light can be completely captured and avoiding light leakage.

[0069] It should be noted that if Figure 7 As shown, the first projection width d1 refers to the width range of the light from the light emitting body 310 hitting the incident surface 200 a along the length direction Y of the light guide bar 200 .

[0070] It is understandable that 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 so that the first projection width d1 completely falls within the width setting range d3 of the inner concave portion, it helps to enable the incident light x of the light emitting body 310 to completely pass through the inner concave portion a1 to form a first divergence, thereby improving the divergence effect of the light and further improving the brightness uniformity of the light when it is emitted.

[0071] Optionally, the surface of the inner concave portion a1 may be a concave arc surface. Figure 2 As shown, the concave direction of the concave arc surface refers to the direction in which the incident surface 200 a is away from the light emitting body 310 .

[0072] Preferably, the illuminator 310 is positioned opposite the deepest position F of the inner recess a1. This helps improve the divergence of light from the illuminator 310 by the inner recess a1 and also helps improve the consistency of the divergence of light from the illuminator 310 extending from the deepest position F of the concave arc surface to both sides, thereby improving the aesthetics. It should be noted that the inner recess a1, as a concave structure, has its deepest position F at the position farthest from the illuminator 310 in the width direction X of the light guide bar 200. At this position, the tangent of the concave arc surface is perpendicular to the width direction X of the light guide bar 200.

[0073] More preferably, the curvature radius of the concave arc surface gradually increases from the deepest position F toward the extending directions on both sides, which helps to further improve the brightness uniformity of the light of the light emitting body 310 when it is emitted from the exit surface 200b.

[0074] Specifically, in this embodiment, the radius of curvature of the concave surface is set to its 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 emitting body 310 is arranged directly opposite the deepest position F of the concave surface, the vast majority of the light from the light emitting body 310 is concentrated near the deepest position F, thereby being able to diverge the vast majority of the light. Conversely, gradually increasing the radius of curvature of the concave surface from the deepest position F toward the sides of the concave surface can gradually reduce the divergence speed of the incident light x along the direction extending from the deepest position F toward the sides. In other words, relatively weak light that deviates further from the deepest position F can maintain its original direction or diverge at a relatively slower speed, thereby improving the overall consistency of light brightness.

[0075] In some embodiments, combined Figure 7 As shown, the curvature radius of the concave arc surface at the farthest position guide angle on both sides of the deepest position F is R1, and the corresponding center angle of the two side 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 meet different conditions with R1, it is only necessary to configure α and β to meet a certain size relationship to achieve the aforementioned first projection width d1 completely falling within the width setting range d3 of the inner recess.

[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 greater distance from the inner recess a1, α must be greater than β to ensure that the first projected width d1 falls completely within the inner recess's width setting range d3, capturing all incident light rays x. When L is less than R1, α can be less than or equal to β, similarly ensuring that the first projected width d1 falls completely within the inner recess's width setting range d3, capturing all incident light rays x. Users only need to design according to this relationship, which improves design simplicity.

[0078] Optionally, continue to Figure 7 There is a spacing d between the deepest positions F of the concave surfaces of two adjacent concave portions a1, and the light of the light-emitting body 310 has a second projection width d2 inside the light guide bar 200. The spacing d is configured so that at least part of the second projection width d2 of the two adjacent light-emitting bodies 310 overlaps with each other, thereby ensuring that the emitted light can completely cover and emit from the exit surface 200b, avoiding uneven brightness and alternating light and dark on the exit surface 200b, which helps to improve the aesthetics.

[0079] Optionally, the surfaces of two adjacent inner recesses a1 are smoothly joined; or, the incident surface 200a includes transition portions a3 arranged at intervals, and the surfaces of the two adjacent inner recesses a1 are smoothly joined via the transition portions a3.

[0080] It can be understood that the first projection width d1 of the light-emitting body 310 on the incident surface 200a only needs to fall completely within the width setting range d3 of the inner recess, so the adjacent inner recesses a1 can be set to be directly smoothly connected or smoothly connected through the first transition portion a3. This helps to avoid sharp corners at the connection position, making the propagation of light more stable and avoiding sudden changes in light.

[0081] As in this embodiment, the inner recesses a1 are arranged to be spaced apart from each other and smoothly joined to the surfaces of two adjacent inner recesses a1 by the transition portion a3. Of course, the transition portion a3 does not have the function of capturing the incident light x and the transition portion a3 can be set to 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 lighting effect.

[0083] Optionally, the reflective material may be, but is not limited to, implemented as white ink, transparent ink, or metal plating.

[0084] Optionally, in some embodiments, the reflective material can be made according to the formula Where η is the light absorption efficiency; k is the material absorption coefficient; Iout is the output light intensity, i.e., the light intensity ultimately emitted from the light guide bar 200 after propagation through the light guide bar 200; Iin is the input light intensity, i.e., the original light intensity emitted from the light source 310, expressed in luminous flux (e.g., lumens) or optical power (e.g., watts).

[0085] Optionally, see Figure 2 The emitting surface 200 b has a plurality of convex portions b1 arranged along the length direction Y of the light guide bar 200 , and each concave portion a1 is disposed opposite to each convex portion b1 in the width direction X of the light guide bar 200 .

[0086] In this embodiment, the glass assembly 10 first has a plurality of inner recesses a1 arranged along the length direction Y of the light guide bar 200 through the incident surface 200a, and a light-emitting body 310 is arranged opposite to an inner recess a1, so that the incident light x of the light-emitting body 310 can form a first divergence through the inner recess a1. In addition, the glass assembly 10 has a plurality of outer protrusions b1 arranged along the length direction Y of the light guide bar 200 through the exit surface 200b, and each inner recess a1 is arranged opposite to each outer protrusion b1 in the width direction X of the light guide bar 200, so that the emitted light of the light-emitting body 310 can form a second divergence through the outer protrusion b1. In this way, the brightness uniformity of the emitted light is improved, the uneven brightness or alternating light and dark in the appearance of the light-emitting component 300 is alleviated, and the aesthetics and user experience are improved.

[0087] Optionally, the surface of the outer convex portion b1 is an outer convex surface. It should be noted that the convex direction of the outer convex portion b1 is the direction in which the emission surface 200 b is away from the light emitting body 310 .

[0093] Based on the above-mentioned glass assembly 10 of the present application, the present application also provides a feasible embodiment of a light guide strip 200 of the glass assembly 10 for reference. Specifically, the parameters of the light guide strip 200 are as follows:

[0094] The incident surface 200a has a curvature radius R1: R1=20 mm.

[0095] The light emitting angle β of the light emitting body 310 is: β=120°.

[0096] Wrap angle α: α=150°.

[0097] According to the relationship , the distance between adjacent light emitting bodies 310 , you can actually choose d=35 mm.

[0098] According to the relationship , the distance between the light emitting body 310 and the inner concave portion a1: (Must satisfy L≤R1).

[0099] It is worth noting that see Figure 7 , according to the relationship The angle of incidence can also be adjusted: (This angle can be adjusted to a practically feasible angle.) It should be noted that according to Fresnel's law of reflection, reflection loss is minimized when light is incident vertically (θ = 0). Therefore, reducing the deviation angle θ between the incident light ray x and the normal to the incident surface 200a can reduce the reflection loss of the incident light ray x and improve the utilization rate of the incident light ray x.
