Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a panel, a panel forming process, and a glass assembly. Background Technology

[0002] With the development of automotive technology, users have increasingly higher requirements for the aesthetics and lightweight design of car exterior windows, demanding that corner windows have high-gloss black or multi-colored appearances, while also meeting lightweight requirements.

[0003] In related technologies, automotive exterior windows generally consist of a glass body and trim strips. The glass body allows light to pass through, enabling passengers inside the vehicle to observe the outside environment. The trim strips are available in various colors to meet aesthetic requirements, and require separately developed stamping or injection molds. During the assembly of the exterior window, the glass body and trim strips are connected and assembled using edge-wrapping injection molding or bonding processes. This process is relatively complex and has high production costs. Furthermore, the trim strips are prone to cosmetic issues such as pressure marks or scratches during assembly with the glass body. Summary of the Invention

[0004] Therefore, it is necessary to provide a panel, a panel molding process, and a glass assembly to simplify the production process of the exterior window, reduce production costs, and improve appearance performance.

[0005] In a first aspect, embodiments of this application provide a panel, including:

[0008] A decorative layer is provided on at least one of the two opposite sides of the decorative part.

[0009] In one embodiment, a functional film layer is further included, which is disposed on at least one of the two opposite sides of the light-transmitting portion, or the functional film layer is embedded in the light-transmitting portion.

[0010] In one embodiment, the thickness of the functional film layer ranges from 0 mm to 5 mm.

[0011] In one embodiment, the light-transmitting portion includes a first transparent base layer, which is connected to the decorative portion.

[0012] In one embodiment, the light-transmitting portion further includes a second transparent substrate, wherein the first transparent substrate and the second transparent substrate are disposed opposite to each other in a first direction.

[0013] In one embodiment, the first transparent substrate and the second transparent substrate are the same color, the number of the second transparent substrate is at least one layer, and the light-transmitting portion further includes an intermediate layer located between the first transparent substrate and the second transparent substrate, and / or, the intermediate layer is located between two adjacent layers of the second transparent substrate.

[0014] In one embodiment, a functional film layer is further included, the functional film layer being located within the intermediate layer, and / or the functional film layer being located on the side of the first transparent substrate facing away from the second transparent substrate, and / or the functional film layer being located in the first direction on the side of the second transparent substrate furthest from the first transparent substrate facing the vehicle interior.

[0015] In one embodiment, the thickness of the first transparent substrate and / or the second transparent substrate is a, where 1mm ≤ a ≤ 10mm.

[0016] In one embodiment, the first transparent substrate and the second transparent substrate are different colors, and the first transparent substrate and the second transparent substrate are connected by a two-color injection molding process or by a snap-fit ​​structure.

[0017] In one embodiment, the first transparent substrate has a snap-fit ​​groove on the side facing the second transparent substrate in the first direction, and the second transparent substrate has a first protrusion, which is inserted into the snap-fit ​​groove.

[0018] In one embodiment, the thickness of the first protrusion is e, 0.5mm≤e≤9.5mm, and the depth to which the first protrusion is inserted into the snap-fit ​​groove is f, 0.5mm≤f≤50mm.

[0019] In one embodiment, the first transparent substrate has a second protrusion on the side facing the second transparent substrate in the first direction, and the second transparent substrate has a snap-fit ​​hole, into which the second protrusion is inserted.

[0020] In one embodiment, the second protrusion includes a main body and a limiting part. The limiting part is provided at one end of the main body facing the vehicle interior in the first direction. In the second direction, the size of the main body is g, and the size of the limiting part is h, where 0.5mm≤g≤5mm and g<h≤10mm.

[0021] In the first direction, the dimension of the limiting part is j, where 0.5mm ≤ j ≤ 9.5mm;

[0022] The first direction and the second direction intersect.

[0023] In one embodiment, in the first direction, the distance between the decorative part and the light-transmitting part is b, where 0mm≤b≤10mm.

[0024] In one embodiment, in the second direction, the size of the decorative part is c, where 0mm ≤ c ≤ 1000mm.

[0025] In one embodiment, an included angle β is formed between the light-transmitting portion and the decorative portion, where 90°≤β≤180°.

[0026] In one embodiment, at least one of the opposite sides of the decorative portion is printed or sprayed with a coating to form the decorative layer.

[0027] Secondly, embodiments of this application also provide a panel forming process for manufacturing the panel described in any one of the first aspects, the panel forming process comprising the following steps:

The decorative section is integrally connected to the light-transmitting section, with at least a portion of the decorative section surrounding the light-transmitting section. A decorative layer is located on at least one of the two opposing sides of the decorative section, fulfilling aesthetic requirements. The light-transmitting section and decorative section are integrally molded. Compared to exterior windows in related technologies, this eliminates the need for separate molds for trim strips, and the glass body and trim strips do not require edging processes for connection. This simplifies the production process of exterior windows, reduces production costs, and, because the light-transmitting section and decorative section are integrally molded, reduces the risk of aesthetic problems with the decorative section, improving overall appearance.

Detailed Implementation

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. 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.

[0052] In related technologies, such as Figure 1 As shown, a car's exterior window typically consists of a glass body 6 and a trim strip 7. The glass body 6 allows light to pass through, enabling passengers inside the vehicle to observe the outside environment. The trim strip 7 can be available in various colors to meet different aesthetic requirements. The trim strip 7 requires a separately developed stamping or injection mold. During the assembly of the exterior window, the glass body 6 and the trim strip 7 are connected using either an edge-wrapping injection molding process or an adhesive bonding process. When the glass body 6 and the trim strip 7 are connected using an edge-wrapping injection molding process, such as... Figure 1 As shown, the glass body 6 and trim strip 7 need to be placed in a mold and injection molded to form an edge band 5'. The trim strip 7 is easily damaged by pressure or scratches, and the burrs from the edge band 5 overflow after injection molding, affecting the appearance. When the glass body 6 and trim strip 7 are connected via the edge band 5 bonding process, the connection between the glass body 6 and trim strip 7 via the edge band 5' is difficult to position and the operation is complex. Therefore, in related technologies, the exterior window manufacturing process for automobiles is relatively complex and has high production costs. Furthermore, the trim strip 7 is prone to damage such as pressure or scratches during assembly with the glass body 6.

[0053] See Figure 2 and Figure 3An embodiment of this application provides a panel including a light-transmitting portion 1 and a decorative portion 2. The light-transmitting portion 1 transmits light into the vehicle interior, allowing passengers inside the vehicle to observe the outside through it. The decorative portion 2 is integrally connected to the light-transmitting portion 1 and is integrally formed, with at least a portion of the decorative portion 2 surrounding the light-transmitting portion 1. A decorative layer 3 is disposed on at least one of the two opposing sides of the decorative portion 2. The decorative layer 3 is used to meet aesthetic requirements. Since the light-transmitting portion 1 and the decorative portion 2 are integrally formed, compared to exterior windows in related technologies, there is no need to separately set molds for the trim strip 7. Furthermore, the glass body 6 and the trim strip 7 do not need to be connected via an edge-wrapping 5 process, simplifying the production process of the exterior window and reducing production costs. Simultaneously, because the light-transmitting portion 1 and the decorative portion 2 are integrally formed, the risk of aesthetic problems with the decorative portion 2 is reduced, improving aesthetic performance.

[0054] It should be noted that the panel is made of a transparent material with a light transmittance of ≥70% to meet the visibility requirements of occupants. The panel can be made of at least one of the following materials: PC, PMMA, PS, ASA, PET, AS, ABS, PVC, TPE (such as TPEE), TPU, PMMA / PC composite materials, and transparent PP, and can be adapted to meet specific usage requirements. The first direction is the thickness direction of the panel (X-axis direction in the figure), and the second direction is the width direction of the panel (Y-axis direction in the figure), intersecting with the first direction. Specifically, the side of the light-transmitting part 1 facing outwards in the first direction refers to the side of the light-transmitting part 1 facing away from the edging 5, and the side of the light-transmitting part 1 facing inwards in the first direction refers to the side of the light-transmitting part 1 facing the edging 5.

[0055] Furthermore, such as Figure 3 and Figure 4 As shown, in order to enable the panel to integrate functional effects (such as dimming, display, antenna, sound insulation, heat insulation, or anti-reflection functions), that is, the panel has dimming function, display function, and antenna or sound insulation function, the panel also includes a functional film layer 4. The functional film layer 4 is a sheet structure or a coating structure, and the functional film layer 4 is disposed on at least one of the two opposite sides of the light-transmitting part 1, or embedded in the light-transmitting part 1. Figure 3 and Figure 4 As shown, in some embodiments, in order to facilitate the rapid formation of the functional film layer 4 on the panel, the functional film layer 4 can be on the side of the light-transmitting part 1 facing the inside of the vehicle in the first direction or on the side of the light-transmitting part 1 facing the outside of the vehicle in the first direction. That is, the functional film layer 4 can be bonded to the light-transmitting part 1 by an adhesive. The functional film layer 4 can be configured accordingly according to the actual functional requirements.

[0056] It should be noted that the thickness of the functional film layer 4 ranges from 0mm to 5mm. Specifically, the thickness of the functional film layer 4 is greater than 0mm and less than or equal to 5mm. If the thickness of the functional film layer 4 is greater than 5mm, it reduces the light transmittance of the light-transmitting part 1 of the panel, thereby affecting visual transparency, optical uniformity, and overall decorative effect.

[0057] Furthermore, such as Figure 5 and Figure 7 As shown, in order to achieve different light transmission effects and shapes, in some embodiments, the light-transmitting part 1 includes a first transparent base layer 11, which is connected to the decorative part 2. In order to simplify the structure of the panel, in one embodiment, at least a portion of the edge of the first transparent base layer 11 extends toward the side facing outward in a first direction to form the decorative part 2, so that the light-transmitting part 1 and the decorative part 2 are integrally formed.

[0058] In other embodiments, the light-transmitting portion 1 further includes a second transparent base layer 12, wherein the first transparent base layer 11 and the second transparent base layer 12 are disposed opposite to each other in a first direction, the first direction being parallel to the thickness direction of the first transparent base layer 11. For example... Figure 5 As shown, the light-transmitting part 1 can be made of a single layer of transparent material (including only the first transparent base layer 11). Or, as... Figure 7 As shown, the light-transmitting part 1 is made of at least two layers of transparent material (including a first transparent base layer 11 and a second transparent base layer 12). The light transmission requirements and shape requirements can be met by adjusting the number of layers of the second transparent base layer 12.

[0059] When the panel is monochrome, such as Figures 3 to 9 As shown, the panel includes at least a first transparent base layer 11. Figure 7 , Figure 8 and Figure 9 As shown, if the panel further includes a second transparent base layer 12, then the first transparent base layer 11 and the second transparent base layer 12 are the same color. In order to facilitate the connection between the first transparent base layer 11 and the second transparent base layer 12, in some embodiments, the light-transmitting part 1 further includes an intermediate layer 13. The number of second transparent base layers 12 is at least one layer. The intermediate layer 13 is located between the first transparent base layer 11 and the second transparent base layer 12, and / or, the intermediate layer 13 is located between two adjacent layers of second transparent base layers 12.

[0060] It should be noted that the intermediate layer 13 is a PVB or TPU layer, used to connect the first transparent base layer 11 and the second transparent base layer 12, or to connect two adjacent second transparent base layers 12. The intermediate layer 13 can bond adjacent transparent base layers and absorb impact energy, while preventing the panel from shattering and splashing, thus improving the stability of the panel structure. Furthermore, to facilitate the arrangement of the functional film layer 4, such as... Figure 8As shown, in one embodiment, the functional film layer 4 is located in a first direction on the side of the second transparent substrate 12 facing inwards from the first transparent substrate 11. Figure 9 As shown, in another embodiment, the functional film layer 4 is located on the side of the first transparent base layer 11 facing away from the second transparent base layer 12, that is, the functional film layer 4 is disposed facing outwards from the vehicle. Figure 8 As shown, in another embodiment, the functional film layer 4 (not shown) is located within the intermediate layer 13, which can reduce the influence of the external environment on the functional film layer 4 and improve its service life. The installation position of the functional film layer 4 can be adaptively adjusted according to the actual function and installation requirements; that is, the functional film layer 4 can be located inside the panel or on the surface of the panel.

[0061] In the above embodiments, to further reduce production costs, the thickness of the decorative part 2 is less than the thickness of the light-transmitting part 1. Raised or recessed structures can be provided on certain surfaces of the light-transmitting part 1 and the decorative part 2 to form fonts, textures, or special patterns, etc., to meet aesthetic requirements.

[0062] like Figure 6 As shown, since the panels are mostly integrally molded using injection molding, and the light-transmitting part 1 includes a first transparent base layer 11 and / or a second transparent base layer 12, in order to facilitate the control of the thickness of the first transparent base layer 11 and the second transparent base layer 12, and to facilitate molding, in one embodiment, when the panel only includes the first transparent base layer 11, the panel is monochrome, and the thickness of the first transparent base layer 11 is 'a', 1mm ≤ a ≤ 10mm. When 'a' is less than 1mm, the first transparent base layer 11 is prone to deformation after molding, resulting in poor panel structural strength, which is not conducive to subsequent installation. When 'a' is greater than 10mm, the thickness of the first transparent base layer 11 is too thick, affecting the light transmission effect. In another embodiment, the panel includes a first transparent base layer 11 and a second transparent base layer 12, the first transparent base layer 11 and the second transparent base layer 12 are the same color, and the panel is monochrome. In this case, similarly, the thickness of the second transparent base layer 12 is 'a', 1mm ≤ a ≤ 10mm. When 'a' is less than 1mm, the second transparent base layer 12 is prone to deformation after molding, resulting in poor panel structural strength, which is not conducive to subsequent installation. When 'a' is greater than 10mm, the thickness of the second transparent base layer 12 is too thick, affecting the light transmission effect. Depending on actual needs, 'a' can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 9mm, or 10mm, etc.

[0063] like Figure 10 , Figure 11 , Figure 12 and Figure 14As shown, when the panel is multi-colored, the first transparent base layer 11 and the second transparent base layer 12 are different colors. The first transparent base layer 11 and the second transparent base layer 12 are connected by a two-color injection molding process or by a snap-fit ​​structure. Figure 10 and Figure 11 As shown, the first transparent base layer 11 and the second transparent base layer 12 are connected by a two-color injection molding process.

[0064] When the first transparent base layer 11 and the second transparent base layer 12 are connected by a snap-fit ​​structure, such as Figure 12 and Figure 13As shown, in some embodiments, the first transparent base layer 11 has a snap-fit ​​groove 111 on the side facing the second transparent base layer 12 in the first direction, and the second transparent base layer 12 has a first protrusion 121, which is inserted into the snap-fit ​​groove 111. Furthermore, to improve the reliability of the snap-fit ​​connection between the first transparent base layer 11 and the second transparent base layer 12, the thickness of the first protrusion 121 is e, where 0.5mm ≤ e ≤ 9.5mm. If the thickness of the first protrusion 121 is less than 0.5mm, the wall thickness of the first protrusion 121 is relatively thin. After being inserted into the snap-fit ​​groove 111, the panel vibration during vehicle operation can easily cause the first protrusion 121 to break, resulting in poor structural strength. If the thickness of the first protrusion 121 is greater than 9.5mm, then the thickness of the first protrusion 121 is close to the thickness of the first transparent base layer 11, resulting in a relatively thin wall thickness of the snap-fit ​​groove 111. This can easily lead to partial breakage at the connection between the snap-fit ​​groove 111 and the first protrusion 121, affecting the reliability of the snap-fit ​​structure. Meanwhile, the depth to which the first protrusion 121 is inserted into the snap-fit ​​groove 111 is f, where 0.5mm ≤ f ≤ 50mm. If f < 0.5mm, the depth to which the first protrusion 121 is inserted into the snap-fit ​​groove 111 is shallow, and the first protrusion 121 is prone to slipping out of the snap-fit ​​groove 111, affecting the reliability of the connection between the first transparent base layer 11 and the second transparent base layer 12. If f > 50mm, the depth to which the first protrusion 121 is inserted into the snap-fit ​​groove 111 is deep, requiring higher processing precision for the first protrusion 121 and the snap-fit ​​groove 111. The first protrusion 121 is prone to jamming when inserted into the snap-fit ​​groove 111, affecting the connection between the first transparent base layer 11 and the second transparent base layer 12. The value of e can be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, or 9.5mm, and the value of f can be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, 7mm, 9mm, 10mm, 12mm, 15mm, 17mm, 20mm, 21mm, 23mm, 25mm, 28mm, 30mm, 33mm, 36mm, 40mm, 42mm, 45mm, 47mm, 49mm, or 50mm. The corresponding dimensions can be adjusted adaptively according to the actual snap-fit ​​requirements. In this embodiment, after the first transparent base layer 11 and the second transparent base layer 12 are connected by the first protrusion 121 and the snap-fit ​​groove 111, the surface of the first transparent base layer 11 facing the inside of the vehicle is flush with the surface of the second transparent base layer 12 facing the inside of the vehicle, so that the first transparent base layer 11 and the second transparent base layer 12 transmit light evenly at the connection point.

[0065] like Figure 14 and Figure 15As shown, when the first transparent base layer 11 and the second transparent base layer 12 are connected by a snap-fit ​​structure, in some embodiments, the first transparent base layer 11 has a second protrusion 112 on the side facing the second transparent base layer 12 in the first direction, and the second transparent base layer 12 has a snap-fit ​​hole 122, into which the second protrusion 112 is inserted. This allows adjustment of the snap-fit ​​position of the first transparent base layer 11 and the second transparent base layer 12 to meet different assembly requirements. Furthermore, this design aims to improve the stability of the snap-fit ​​structure between the first transparent base layer 11 and the second transparent base layer 12. In one embodiment, the second protrusion 112 includes a main body 1121 and a limiting part 1122. The limiting part 1122 is provided at the end of the main body 1121 facing the vehicle interior in a first direction. Specifically, in the second direction, the size of the main body 1121 is g, and the size of the limiting part 1122 is h, where 0.5mm ≤ g ≤ 5mm, and g < h ≤ 9.5mm. g can take values ​​of 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, and h can take values ​​of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 8.5mm, or 9.5mm. As shown in the figure, when g < h, the second protrusion 112 forms an inverted snap structure after being inserted into the snap-fit ​​hole 122, thus preventing the second protrusion 112 from coming out after being inserted into the snap-fit ​​hole 122. Meanwhile, to improve the structural strength of the limiting part 1122, the dimension of the limiting part 1122 in the first direction is j, where 0.5mm ≤ j ≤ 9.5mm, and j can take values ​​of 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm. If j is less than 0.5mm, the thickness of the limiting part 1122 in the first direction is relatively thin. Therefore, after the second protrusion 112 is inserted into the snap-fit ​​hole 122, during vehicle operation, panel vibration can easily cause the connection between the limiting part 1122 and the main body 1121 to break, affecting the connection strength of the first transparent base layer 11 and the second transparent base layer 12. If j > 9.5mm, the thickness of the snap-fit ​​hole 122 in the first direction is relatively thin, which can easily lead to weak structural strength of the part of the second transparent base layer 12 near the snap-fit ​​hole 122. During vehicle operation, panel vibration can easily cause the snap-fit ​​hole 122 to crack, affecting the connection strength of the first transparent base layer 11 and the second transparent base layer 12.

[0066] In the above embodiment, the snap-fit ​​hole 122 is a countersunk hole structure. After the second protrusion 112 is inserted into the snap-fit ​​hole 122, the end face of the limiting part 1122 facing away from the main body part 1121 is flush with the surface of the second transparent base layer 12, so that the first transparent base layer 11 and the second transparent base layer 12 transmit light evenly at the connection.

[0067] Furthermore, to improve the stability of the panel structure, in one embodiment, such as... Figure 6 As shown, in the first direction, the maximum distance between the decorative part 2 and the light-transmitting part 1 on the side facing outwards is b, where 0mm ≤ b ≤ 10mm. When b = 0, in the first direction, the light-transmitting part 1 and the decorative part 2 are flush on the side facing outwards. When 0mm < b ≤ 10mm, in the first direction, the light-transmitting part 1 and the decorative part 2 are positioned sequentially away from the vehicle interior, and b can take values ​​of 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, or 10mm. When b > 10mm, the decorative part 2 extends a large dimension outwards in the first direction, forming a cantilever structure. During injection molding, the side of the decorative part 2 away from the light-transmitting part 1 is prone to deformation.

[0068] Furthermore, such as Figure 6 As shown, in the second direction, the size of the decorative part 2 is c, where 0 ≤ c ≤ 1000 mm. Thus, when the panel is installed with the window, the light-transmitting part 1 is located inside the window, and the edge of the decorative part 2 has sufficient space to provide the edging 5 for sealing after connection with the window edge. It should be noted that when c = 0, the decorative part 2 is not provided in a certain area of ​​the light-transmitting part 1. The position of the decorative part 2 can be adaptively adjusted according to the installation position of the panel. In some other embodiments, when the panel is installed in a certain area of ​​the rear side window of the vehicle, the light transmission requirement is lower, and the panel can be entirely composed of the decorative part 2. If c > 1000 mm, the size of the decorative part 2 is large, affecting the light transmission performance inside the vehicle and impacting the passenger experience. The value of c can be 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm, 850mm, 900mm, 950mm, or 1000mm, etc. The value of c can be adjusted adaptively according to the actual installation position of the panel and the light transmission requirements.

[0069] Furthermore, such as Figure 6As shown, since the panel is formed using injection molding, an angle β is formed between the light-transmitting part 1 and the decorative part 2, where 90°≤β≤180°. This facilitates demolding after the light-transmitting part 1 and the decorative part 2 are integrally molded. If β<90°, the angle between the light-transmitting part 1 and the decorative part 2 is acute, and the panel forms an inverted structure in the first direction, making unidirectional demolding impossible. A core-pulling mechanism must be added in other directions, resulting in a more complex mold structure and higher production costs. When 90°≤β≤180°, the panel can be directly demolded in the first direction, reducing production costs. β can take values ​​of 90°, 100°, 110°, 120°, 125°, 130°, 135°, 140°, 150°, 155°, 160°, 165°, 170°, 175°, or 180°, and the value of β can be adaptively adjusted according to actual styling requirements.

[0070] Furthermore, such as Figure 3 and Figure 4 As shown, to facilitate the formation of the decorative layer 3, in some embodiments, at least one of the opposite sides of the decorative part 2 is printed or sprayed with a coating to form the decorative layer 3. That is, the decorative layer 3 can be formed by printing or spraying a coating of different colors (including but not limited to black, silver, red, white, blue, etc.) on at least one of the opposite sides of the decorative part 2 through printing or spraying processes to meet the appearance requirements of the decorative part 2. In this application, the decorative part 2 can replace the trim strip 7 in related technologies, greatly reducing production costs.

[0071] Based on the same concept, this application also provides a panel forming process for manufacturing the aforementioned panel. The panel forming process includes the following steps:

[0072] S1. A substrate is formed by injection molding using a transparent material; a light-transmitting portion 1 is formed in the area near the center of the substrate, and a decorative portion 2 is formed in at least a portion of the edge of the substrate, with the decorative portion 2 surrounding the light-transmitting portion 1.

[0073] S2. A decorative layer 3 is provided in the decorative section 2.

[0074] In step S1, the light transmittance of the transparent material (specifically, the transmittance of visible light, with a wavelength range of 380nm-780nm) is greater than or equal to 70% to meet the observation requirements of occupants inside the vehicle. The transparent material can be at least one of the following: PC, PMMA, PS, ASA, PETAS, ABS, PVC, TPE (such as TPEE), TPU, PMMA / PC composite materials, and transparent PP. The selection of the above materials can be based on the specific installation location of the panel and the requirements for light transmission and decoration. It should be noted that, for example... Figures 7 to 9As shown, when the panel is monochrome and the light-transmitting part 1 is composed of multiple layers of boards, step S1 specifically includes injection molding a first transparent base layer 11 and a second transparent base layer 12 using transparent materials of the same color. Then, the first transparent base layer 11 enters the subsequent steps S2 and S3. Finally, in step S4, the first transparent base layer 11 and the second transparent base layer 12 are connected by an intermediate layer 13.

[0075] like Figure 11 , Figure 12 and Figure 14 As shown, when the panel is multi-colored and the light-transmitting part 1 is composed of different colored boards, the first transparent base layer 11 and the second transparent base layer 12 are different colors. In step S1, the first transparent base layer 11 and the second transparent base layer 12 are formed into a substrate by a two-color injection molding process, or the first transparent base layer 11 and the second transparent base layer 12 are formed by injection molding using transparent materials of different colors respectively. The first transparent base layer 11 enters the subsequent step S2. Finally, in step S3, the first transparent base layer 11 and the second transparent base layer 12 are connected by a snap-fit ​​structure or adhesive, and the corresponding surface treatment is performed to form a panel.

[0076] In step S1, after the substrate is formed, a light-transmitting portion 1 is formed in the area near the center of the substrate, and a decorative portion 2 is formed in at least a portion of the edge of the substrate. The decorative portion 2 surrounds the light-transmitting portion 1 to meet the requirements of light transmission and decoration. The light-transmitting portion 1 can be divided into a transparent area and a shielding area. A coating of different colors is printed or sprayed on one of the two opposite sides of the light-transmitting portion 1 to form a shielding area to meet the shielding requirements. The size of the shielding area can be adjusted to adapt the field of view or appearance of the light-transmitting portion 1.

[0077] In step S2, a decorative layer 3 is formed on at least one of the opposite sides of the decorative part 2 by printing or spraying a coating of different colors (including but not limited to black, silver, red, white, blue, etc.).

[0078] Furthermore, to ensure the panel has sufficient structural strength or fulfills its functions, step S3 is included after step S2: surface hardening treatment of the substrate or setting of a functional film layer 4 to form the panel. Specifically, in step S3, the surface of the substrate is hardened (including but not limited to spray coating, baking paint, or dip coating) to improve the overall structural strength of the panel. Alternatively, a relevant functional film layer 4 (including but not limited to integrated dimming, display, antenna, sound insulation, heat insulation, and anti-reflection functions) is set on the surface of the substrate. When the panel is monochrome and multi-layered, in step S3, the first transparent base layer 11 and the second transparent base layer 12 are connected through an intermediate layer 13. The functional film layer 4 can also be set within the intermediate layer 13. It should be noted that the surface hardening treatment of the substrate can be performed before or after the connection of the first transparent base layer 11 and the second transparent base layer 12. That is, the first transparent base layer 11 and the second transparent base layer 12 can be hardened separately before being connected, or the first transparent base layer 11 and the second transparent base layer 12 can be hardened as a whole after being connected through the intermediate layer 13. The process can be adapted to actual production needs.

[0079] After the panel is formed, the edge 5 is connected to the trim part 2 by edge injection molding or bonding process to form a glass assembly. Then, the light-transmitting part 1 is connected with the nail column by injection molding or bonding process to facilitate the connection between the glass assembly and the vehicle body environmental parts.

[0080] Based on the same concept, this application also provides a glass assembly, including a edging 5 and the aforementioned panel, wherein at least a portion of the edging 5 surrounds and is connected to the decorative portion 2. Figure 5 or Figure 7 As shown, the edging 5 is located on the side of the trim section 2 facing the interior of the vehicle in the first direction, and is used for sealing when the glass assembly is connected to the vehicle body. That is, when the glass assembly is installed with the vehicle body, it is assembled with the vehicle body in the first direction so that the side of the edging 5 facing away from the trim section 2 abuts against and is pressed to seal the vehicle body. It should be noted that, in order to facilitate the connection between the edging 5 and the trim section 2, the edging 5 can be formed by bonding or injection molding. When the edging 5 is formed by injection molding, the panel needs to be placed in the mold, and the panel and the mold together form a cavity for forming the edging 5.

[0081] In related technologies, such as Figure 1 As shown, the glass body 6 and the trim strip 7 are connected by edge-wrapping injection molding. The edge-wrapping 5' needs to wrap around the opposite edges of the glass body 6 and the trim strip 7, resulting in a complex mold structure. At the same time, the edge-wrapping 5' uses a large amount of material and is thick, leading to high production costs. However, in the glass assembly of this application, the edge-wrapping 5 only needs to be connected to the decorative part 2 and does not need to be connected to the light-transmitting part 1. This simplifies the mold structure during edge-wrapping injection molding and reduces the amount of material used in the edge-wrapping 5, thereby lowering production costs.

[0082] Furthermore, in one embodiment, the glass assembly further includes a post connected to the light-transmitting portion 1. The post serves to connect the glass assembly to the vehicle body environmental components. Specifically, the post and the light-transmitting portion 1 can be connected by adhesive bonding or injection molding.

[0083] Based on the same concept, this application also provides a vehicle, which includes a body and the aforementioned glass assembly. The glass assembly can be one of a sunroof, side windows, a windshield, or a rear windshield. The glass assembly is connected to the body sheet metal or roof and other environmental components. The edging 5 is disposed between the panel and the environmental components to form a sealing structure, effectively blocking external wind, rain, dust, road noise, airflow whistling, and moisture from entering the interior of the passenger compartment, significantly improving the passenger compartment's driving comfort, environmental adaptability, and overall vehicle durability and reliability.

[0084] 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.

[0085] 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.
