Abstract
Description
Vehicle, glass assembly and manufacturing method thereof
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on February 22, 2024, with application number 202410198528.8 and titled “Vehicle, Glass Assembly and Manufacturing Method Thereof”, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present application relates to the field of glass technology, and in particular to a vehicle, a glass assembly, and a manufacturing method thereof. Background Art
[0004] With the development of the automotive industry, more and more vehicles are equipped with ambient lighting, which can enhance the aesthetics of the interior. Glass assemblies in related technologies include two-piece and three-piece types. A two-piece glass assembly typically includes an outer glass sheet, a light guide block, an inner glass sheet, a light source, and a light-emitting pattern layer. The light-emitting pattern layer is printed on the outer surface of the inner glass sheet, and the light guide block is bonded to the inner glass sheet with optical glue or optical tape. When light from the light source is refracted through the light guide block onto the inner glass sheet, the light-emitting pattern layer emits light, and the color is controllable, creating an ambient light effect.
[0005] However, when the light guide block in the related art is bonded to the surface of the glass using optical glue, the optical glue has a low viscosity, generally around 700mpas-3000mpas. Due to the effect of gravity, especially on curved glass, it will flow and diffuse, and the preset glue thickness cannot be guaranteed. Even if thixotropic glue is used, it is still impossible to completely guarantee a uniform thickness. At the same time, using thixotropic glue on all sides reduces the light transmission area, resulting in poor optical effect. After bonding, the glue overflowing on the four sides needs to be cleaned. When optical tape is used to connect the light guide block to the surface of the glass, the optical tape is usually first applied to the light guide block and then bonded to the glass. When the light guide block and the glass are bonded, since both are hard, bubbles are easily generated during the bonding process and wrapped around the bonding surface. In addition, the assembly operation needs to be performed in a vacuum environment, which is cumbersome and inefficient. Summary of the Invention

[0042] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0043] Referring to Figures 1 and 2, Figure 1 shows a schematic structural diagram of a glass assembly according to an embodiment of the present application. Figure 2 shows a schematic structural diagram of the structure shown in Figure 1 from above. A glass assembly provided in an embodiment of the present application includes: a glass body 10, a light-inducing medium 20, and an adhesive component 30. The glass body 10 is provided with a first main surface 101 facing the internal environment. Specifically, the glass body 10 is further provided with a second main surface 102 facing the external environment, that is, the first main surface 101 and the second main surface 102 are respectively provided on two opposite side surfaces of the glass body 10, for example.
[0044] It should be noted that the glass assembly includes, but is not limited to, being installed on a vehicle, a building, or other main structure, and can be flexibly adjusted and installed according to actual needs, and is not limited here. Specifically, when the glass body 10 is, for example, a vehicle window glass, the internal environment corresponds to the indoor environment of the vehicle, and the external environment corresponds to the outdoor environment of the vehicle.
[0045] Please refer to Figures 1, 3 and 4. Figures 3 and 4 show schematic structural diagrams of the glass assemblies of two other embodiments of the present application. In some embodiments, the glass body 10 includes but is not limited to being set as single-layer glass (as shown in Figure 4) or laminated glass (as shown in Figure 1 or Figure 3), etc., and can be flexibly adjusted and set according to actual needs. In the present embodiment, please refer to Figures 1 and 3. When the glass body 10 is set as laminated glass, the glass body 10 includes an inner glass 11, an intermediate layer 12 and an outer glass 13 connected in sequence. Optionally, the intermediate layer 12 includes but is not limited to PVB material, EVA material, TPU material or SGP material, which can realize the connection and fixation of the inner glass 11 and the outer glass 13.
[0046] Furthermore, the light-introducing medium 20 has a first surface 21, which is connected and fixed to the first main surface 101 via an adhesive assembly 30. The adhesive assembly 30 includes a first adhesive member 31 and a second adhesive member 32. The first adhesive member 31 is disposed around the periphery of the first surface 21 to form a non-enclosed annular structure. The second adhesive member 32 is filled in the space 40 enclosed by the first adhesive member 31, the first surface 21, and the first main surface 101 and is cured by a curable liquid.
[0047] Please refer to Figures 1, 3 and 4 again. The glass assembly also includes a light source 60. The light source 60 is arranged on the first main surface 101 and is located at one end of the light-introducing medium 20. The light from the light source 60 enters the light-introducing medium 20. The light-introducing medium 20 is used to introduce the light from the light source 60 into the glass body 10.
[0048] It should be noted that the light-guiding medium 20 includes but is not limited to straight bars, curved bars, and plates with regular shapes such as triangles, rectangles, trapezoids, pentagons, and other irregular shapes along the length direction. It can be flexibly adjusted and set according to actual needs and is not limited here.
[0049] In this embodiment, the light-inducing medium 20 is specifically described as a rectangular strip, but the invention is not limited thereto. The light-inducing medium 20 also includes a second surface 22 disposed opposite the first surface 21, including but not limited to being parallel to the first surface 21. When the first surface 21 and the second surface 22 are arranged parallel to each other, the light from the luminous source 60 enters the light-inducing medium 20 and is thereby incident upon the glass body 10. The light propagates within the glass body 10, where it is reflected by a prefabricated luminous pattern layer, which emits light, achieving a lighting or atmosphere effect with high incident efficiency. Furthermore, the shape of the light-inducing medium 20 is more regular than that of a wedge, arc, or other irregular shape, reducing processing difficulty and improving production efficiency.
[0050] The first adhesive member 31 includes one or more combinations of optical solid glue, optical adhesive tape, optical adhesive stick and optical adhesive strip.
[0051] During assembly of the aforementioned glass assembly, the first adhesive member 31 is first attached to the periphery of the first surface 21 and the first main surface 101. Since the first adhesive member 31 utilizes optical solid glue, optical tape, an optical adhesive stick, or an optical adhesive strip, it supports the light-introducing medium 20, enabling the light-introducing medium 20 to be initially fixed to the glass body 10 and creating a gap between the light-introducing medium 20 and the glass body 10. Liquid is then injected into the space 40 enclosed by the first adhesive member 31, the first surface 21, and the first main surface 101, and cured to form the second adhesive member 32. Thus, the thickness of the second adhesive member 32 depends on the thickness of the first adhesive member 31. Since the thickness of the first adhesive member 31 can be well controlled, the thickness of the second adhesive member 32 can also be easily controlled, thereby improving the accuracy and uniformity of the adhesive thickness. Furthermore, adhesive overflow can be significantly reduced, thereby reducing cleaning operations and improving product quality and assembly efficiency.
[0052] Referring to Figures 1 and 2 , in one embodiment, the optical tape is configured as a transparent double-sided optical tape. Compared to the opaque double-sided tape used in related art, the transparent double-sided optical tape helps improve optical access, thereby enhancing the ambient lighting effect. Furthermore, the two opposing side surfaces of the double-sided optical tape are respectively bonded to the first surface 21 and the first main surface 101, thereby stably securing the light-guiding medium 20 to the glass body 10. Compared to optical fixing glue, optical adhesive sticks, or optical adhesive strips, the assembly is more stable.
[0053] Referring to Figures 1 and 2 , the thickness d1 of the double-sided optical tape determines the distance between the first surface 21 and the first main surface 101, thereby determining the thickness of the adhesive assembly 30. This allows for precise control and adjustment of the adhesive thickness. The specific thickness d1 of the double-sided optical tape can be flexibly adjusted and controlled based on actual adhesive thickness requirements and is not limited herein.
[0054] Referring to Figures 1 and 2, in one embodiment, the double-sided optical tape has a width W1, 2mm≤W1≤20mm. This facilitates batch production, prevents bubbles from forming during bonding, provides good sealing, and ensures optical quality.
[0055] 1 and 2 , in one embodiment, the double-sided optical tape has a thickness d1, 0.5 mm ≤ d1 ≤ 5 mm. This prevents adhesive overflow, provides good sealing, and ensures optical effects.
[0056] It should be noted that the non-closed annular structure specifically refers to selecting one point on the first adhesive 31 as the starting point, moving from the starting point along the extension direction of the first adhesive 31, and being unable to return to the starting point. In other words, the non-closed annular structure includes a head end and a tail end, and the head end and the tail end are spaced apart to form an injection port 33. Please refer to Figures 5 and 6. During the assembly step, the curable liquid is injected into the space area 40 enclosed by the first adhesive 31, the first surface 21 and the first main surface 101 through the injection port 33, and is cured to obtain the second adhesive 32.
[0057] Referring to Figures 5 and 6 , in some embodiments, the non-enclosed annular structure includes, but is not limited to, regular shapes such as rectangles, triangles, pentagons, hexagons, circles, and ellipses, as well as other irregular shapes, with an injection port 33. Specifically, the non-enclosed annular structure can be configured to suit the shape of the light-introducing medium 20. In this embodiment, the light-introducing medium 20 is configured as a rectangle, and the non-enclosed annular structure is correspondingly configured as a rectangle with an injection port 33.
[0058] Referring to Figures 5 and 6, in one embodiment, the non-enclosed annular structure includes a first stopper 311, a second stopper 312, and a third stopper 313, which are connected in sequence. The first stopper 311 and the third stopper 313 are spaced apart to form an injection port 33. Thus, during the assembly of the glass assembly, the spatial region 40 formed by the first stopper 311, the second stopper 312, the third stopper 313, the light-inducing medium 20, and the glass body 10 cooperates to form, for example, a groove with three sealed edges. During glue injection, the glue nozzle 70 is inserted into the injection port 33 to inject liquid into the groove. During the glue injection process, the glue nozzle 70 moves along the injection port 33, shortening the glue flow and enabling the liquid to quickly and evenly fill the groove. In addition, the thickness of the liquid depends on the respective thicknesses of the first stopper 311, the second stopper 312, and the third stopper 313, enabling accurate control and adjustment.
[0059] Referring to Figures 5 and 6 , in some embodiments, the first stopper 311, the second stopper 312, and the third stopper 313 have the same thickness, thereby improving the sealing performance of the three side portions of the groove. Of course, in some embodiments, the shapes and thicknesses of the first stopper 311, the second stopper 312, and the third stopper 313 may also vary. Specifically, they may be flexibly adjusted and configured based on the shapes of the glass body 10 and the light-introducing medium 20, as long as the first stopper 311, the second stopper 312, and the third stopper 313 are tightly connected to the first surface 21 and the first main surface 101, respectively, to ensure sealing performance.
[0060] Generally speaking, the automotive industry has strict requirements on the weather resistance of materials, and acrylic optical adhesives usually cannot meet the requirements.
[0061] Referring to Figures 3 and 4 , in one embodiment, the glass assembly further includes a protective member 50, which is disposed circumferentially around the adhesive assembly 30 and avoids the position opposite the light source 60. Specifically, the protective member 50 is connected to the adhesive assembly 30 and positioned around the light-inducing medium 20 to seal and protect the adhesive assembly 30, preventing the weather-sensitive adhesive assembly 30 from experiencing aging defects such as rosettes when exposed to air. Furthermore, the protective member 50 is not required in the position opposite the light source 60, to avoid blocking light and affecting the lighting effect.
[0062] Specifically, the protective member 50 includes but is not limited to protective glue, protective film or other protective materials. In this embodiment, protective glue is specifically selected for example. By applying the protective glue to the periphery of the adhesive component 30, the adhesive component 30 is isolated from the air, thereby sealing and protecting the adhesive component 30 and improving assembly efficiency.
[0063] 3 and 4 , in one embodiment, the protection member 50 is further connected to the light-introducing medium 20 and is disposed around the circumference of the light-introducing medium 20 and avoids a position opposite to the light source 60 .
[0064] The protective member 50 may cover only the outer circumferential edge of the second adhesive member 32, or may cover the outer circumferential edge of the second adhesive member 32 and at least partially cover the outer circumferential edge of the first adhesive member 31. Specifically, the protective member 50 may cover the outer circumferential edge of the entire assembly formed by the first and second adhesive members 31, 32, providing a sealing and protective effect for both the first and second adhesive members 31, 32, thereby effectively preventing the first and second adhesive members 31, 32 from developing aging rosette defects when exposed to air. Alternatively, the protective member 50 may cover only the surface of the second adhesive member 32, specifically at the injection port 33, thereby sealing and protecting the side of the second adhesive member 32 exposed through the injection port 33, thereby effectively preventing the second adhesive member 32, which is more susceptible to aging rosette defects due to exposure to air, from developing aging rosette defects. Alternatively, the protective member 50 may cover the surface of the second adhesive member 32 and also cover a portion of the outer surface of the first adhesive member 31.
[0065] In some embodiments, the refractive index of the second adhesive is 1.45-1.65, preferably 1.55-1.6; the visible light transmittance (TL) of the second adhesive is ≥90%, preferably 99.5%-99.9%; and the haze of the second adhesive is ≤5%, preferably ≤1%.
[0066] In one embodiment, the second adhesive may be, but is not limited to, optically clear adhesive (OCA), liquid optical clear adhesive (LOCA), or optically clear resin (OCR).
[0067] In some embodiments, the light-introducing medium 20 and the inner glass 11 are made of the same glass material. The glass material includes, but is not limited to, inorganic glass or organic glass. Specifically, the light-introducing medium 20 is made of ultra-clear glass.
[0068] In one embodiment, the glass assembly further includes a luminous pattern layer (not shown). The luminous pattern layer is disposed on the surface and / or interior of the glass body 10, including but not limited to being disposed on any side surface of the inner glass 11 and any side surface of the outer glass 13. The specific configuration and arrangement can be flexibly adjusted based on actual needs. Light from the luminous light source 60 enters the light-inducing medium 20, which is used to guide the light from the luminous light source 60 into the glass body 10. The luminous pattern layer reflects the light from the luminous light source 60, allowing the luminous pattern to be observed within the internal environment.
[0069] Referring to FIG. 1 and FIG. 2 , in one embodiment, a vehicle, including but not limited to a car, bus, sedan, public bus, coach, truck, jeep, train, high-speed rail, etc., includes the glass assembly of any of the above embodiments.
[0070] During the assembly of the glass assembly of the aforementioned vehicle, the first adhesive 31 is first attached to the periphery of the first surface 21 and the first main surface 101. Since the first adhesive 31 utilizes optical solid glue, optical tape, an optical adhesive stick, or an optical adhesive strip, it supports the light-introducing medium 20, enabling the light-introducing medium 20 to be initially fixed to the glass body 10 and creating a gap between the light-introducing medium 20 and the glass body 10. Liquid is then injected into the space 40 enclosed by the first adhesive 31, the first surface 21, and the first main surface 101, and cured to form the second adhesive 32. In this manner, the thickness of the second adhesive 32 depends on the thickness of the first adhesive 31. Since the thickness of the first adhesive 31 can be well controlled, the thickness of the second adhesive 32 can also be easily controlled, thereby improving the accuracy and uniformity of the adhesive thickness. Furthermore, adhesive overflow can be significantly reduced, thereby reducing cleaning operations and improving product quality and assembly efficiency.
[0071] Referring to FIG. 1 , FIG. 2 , FIG. 5 , and FIG. 6 , in one embodiment, a method for manufacturing a glass assembly includes the following steps:
[0072] Step S100: First, the first adhesive member 31 is connected to the first main surface 101 of the glass body 10 and the first surface 21 of the light-introducing medium 20, respectively, so that the first adhesive member 31 is arranged around the periphery of the first surface 21 to form a non-closed annular structure; wherein the first adhesive member 31 includes one or more combinations of optical solid glue, optical tape, optical glue stick, and optical adhesive strip;
[0073] In step S200, a curable liquid is injected into and completely fills the space 40 enclosed by the first adhesive 31, the first surface 21, and the first main surface 101, and then cured to obtain the second adhesive 32. In this manner, the thickness of the second adhesive 32 depends on the thickness of the first adhesive 31. Since the thickness of the first adhesive 31 can be well controlled, the thickness of the second adhesive 32 can also be easily controlled, thereby improving the accuracy and uniformity of the adhesive thickness. Furthermore, adhesive overflow can be greatly reduced, thereby reducing cleaning operations and improving product quality and assembly efficiency.
[0074] Since the liquid is injected into and fully fills the space region 40 enclosed by the first adhesive 31 , the first surface 21 and the first main surface 101 , gaps can be avoided, thereby improving the optical effect.
[0075] In addition, the liquid specifically uses optical glue whose refractive index is the same or almost the same as that of the inner glass 11. After the liquid is solidified and formed, the light-inducing medium 20 and the inner glass 11 can be connected as one. There is no interface at the connection part, which can prevent refraction or reduce the refraction to a minimum, thereby further improving the optical effect.
[0076] Please refer to Figures 3, 5 and 6. In some embodiments, the manufacturing method further includes: step S300, after the liquid is solidified to obtain the second adhesive member 32, a protective member 50 is set on the exposed wall surface of the second adhesive member 32, or on the exposed wall surface of the first adhesive member 31 and the exposed wall surface of the second adhesive member 32.
[0077] The protective member 50 includes but is not limited to protective glue, protective film or other protective materials, as long as it is set on the exposed wall surface of the adhesive member and can isolate the exposed wall surface of the adhesive member from the air, thereby playing a sealing and protective role.
[0078] In some embodiments, in step S200, the glue nozzle 70 is inserted into the space region 40 through the injection port 33 of the non-enclosed annular structure. During the glue injection process, the glue nozzle 70 is moved from one side of the injection port 33 to the other side of the injection port 33 along the width direction W2 of the injection port 33. In this way, the liquid gradually fills all parts of the space region 40 along the width direction W2, which can help to quickly and evenly fill the space region 40 with liquid.
[0079] Specifically, the moving speed of the glue nozzle 70 is set to a uniform speed, for example, including but not limited to various values such as 0.05m / S, 0.08m / S, 0.1mm / S, 0.2mm / S, etc., as long as the glue can evenly fill the space area 40.
[0080] Referring to Figures 3, 5, and 6, in some embodiments, the nozzle 70 is flat, allowing it to easily penetrate into the space 40 through the injection port 33. Furthermore, the distance S between the two opposing sidewalls of the discharge channel of the nozzle 70 gradually increases along the discharge direction. Thus, the flat, trumpet-shaped nozzle 70 can increase the injection speed.

For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0082] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.
