Description

Technical Field

[0001] This application relates to the field of vehicle glass technology, and in particular to a glass edging assembly and its manufacturing method, and a vehicle. Background Technology

[0002] The vehicle glass edging assembly can be manufactured using a one-piece injection molding process. The glass and trim panel are placed in an injection mold, and then edging material is injected into the mold, ultimately connecting the glass and trim panel together through the edging. The edging material is molten during injection. As it cools, its volume shrinks compared to its molten state, creating a shrinkage force on the trim panel. This shrinkage force can easily cause surface defects in the trim panel.

[0003] One type of vehicle glass edging assembly involves adding an insert between the glass and the trim panel during the edging process. This reduces the space between the trim panel and the glass, thereby reducing the amount of edging material used and the thickness of the resulting edging. Consequently, the shrinkage force exerted by the edging on the trim panel is reduced. However, the use of the insert increases manufacturing costs and can also affect production efficiency. Summary of the Invention

[0004] Based on this, a glass edging assembly and its manufacturing method, as well as a vehicle, are provided, which aim to reduce the possibility of appearance defects in the trim panel, while reducing manufacturing costs and improving production efficiency.

During the injection and cooling of the edging material, the second limiting structure, in cooperation with the first limiting structure, continuously limits the decorative panel. This limiting effect can counteract the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the decorative panel and reducing the possibility of appearance defects. Furthermore, the glass edging assembly in this embodiment does not require inserts during manufacturing, thus reducing manufacturing costs and improving production efficiency.

[0017] An edge-sealing material is injected into the injection mold, and after the edge-sealing material cures, it forms an edge and connects the glass and the decorative panel into one piece.

[0018] In some embodiments, the outer diameter of the first limiting structure is smaller than the diameter of the through hole;

[0019] The process of injecting edge-sealing material into the injection mold includes:

Then, edging material is injected into the injection mold. After the edging material cools and solidifies, the edging is formed, connecting the glass and trim panel integrally. During the injection and cooling of the edging material, the second limiting structure, in cooperation with the first limiting structure, consistently limits the trim panel. This limiting effect counteracts the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the trim panel's appearance and reducing the possibility of appearance defects. Furthermore, the glass edging assembly in this embodiment does not require inserts during manufacturing, thus reducing manufacturing costs and improving production efficiency.

[0051] The vehicle glass edging assembly can be manufactured using a one-piece injection molding process. The glass and trim panel are placed in an injection mold, and then edging material is injected into the mold, ultimately connecting the glass and trim panel together through the edging. The edging material is molten during injection. As it cools, its volume shrinks compared to its molten state, creating a shrinkage force on the trim panel. This shrinkage force can easily cause surface defects in the trim panel.

[0052] One type of vehicle glass edging assembly involves adding an insert between the glass and the trim panel during the edging process. This reduces the space between the trim panel and the glass, thereby reducing the amount of edging material used and the thickness of the resulting edging. Consequently, the shrinkage force exerted by the edging on the trim panel is reduced. However, the use of the insert increases manufacturing costs and can also affect production efficiency.

[0053] Based on this, an embodiment of the first aspect of this application provides a glass edging assembly designed to reduce the possibility of appearance defects in the trim panel, while also reducing manufacturing costs and improving production efficiency.

[0054] like Figures 1 to 4As shown, in some embodiments, the glass edging assembly 10 includes a glass 100, a decorative panel 200, and an edging 300. Specifically, the edging 300 is disposed between the glass 100 and the decorative panel 200, and the edging 300 is formed by injection molding and connects the glass 100 and the decorative panel 200 as a whole. The glass 100 has a through hole 101, and the decorative panel 200 has a first limiting structure 201, which passes through the through hole 101 and is used to cooperate with a second limiting structure 23 on the injection mold.

[0055] The glass edging assembly 10 in this embodiment can be manufactured by integral injection molding. The injection mold used during injection molding is equipped with a second limiting structure 23. Specifically, the glass 100 and the decorative panel 200 can be placed in the injection mold. After placement, the first limiting structure 201 on the decorative panel 200 passes through the through hole 101 in the glass 100 and cooperates with the second limiting structure 23. Then, edging material is injected into the injection mold. After the edging material cools and solidifies, an edging 300 is formed, connecting the glass 100 and the decorative panel 200 as a whole. During the injection and cooling of the edging material, the second limiting structure 23, through its cooperation with the first limiting structure 201, consistently provides support and limitation for the decorative panel 200. This support and limitation can counteract the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the decorative panel 200's appearance and reducing the possibility of appearance defects. In addition, the glass edging assembly 10 in this embodiment does not require inserts during the manufacturing process, thus reducing manufacturing costs and improving production efficiency.

[0056] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the end of the first limiting structure 201 away from the trim panel 200 protrudes from the surface of the glass 100 on the side away from the trim panel 200. This arrangement gives the first limiting structure 201 a certain height, thus enhancing the support and limiting effect on the trim panel 200 when the first limiting structure 201 and the second limiting structure 23 cooperate. Furthermore, the protrusion of the end of the first limiting structure 201 away from the trim panel 200 from the surface of the glass 100 on the side away from the trim panel 200 also prevents the edging material from contacting and adhering to the second limiting structure 23. This reduces the difficulty of demolding, allowing the finished glass edging assembly 10 to be more easily removed from the injection mold.

[0057] In some embodiments, the decorative panel 200 is made of plastic. The plastic decorative panel 200 can have a wider area for free shaping, which can be formed into patterns or artistic text through hot stamping, thereby improving the aesthetics of the decorative panel 200 and enhancing its decorative function.

[0058] In one embodiment, such as Figure 5 As shown, the decorative panel 200 is a single-material panel. For example, the decorative panel 200 can be a panel structure made of PMMA (polymethyl methacrylate) material.

[0059] In another embodiment, such as Figure 6 As shown, the decorative panel 200 is a composite material panel, which may include a first panel 210 and a second panel 220 joined together. The second panel 220 is located on the side of the first panel 210 closer to the glass 100. The first panel 210 and the second panel 220 are made of different materials. A first limiting structure 201 is disposed on the second panel 220. Exemplarily, the first panel 210 is made of PMMA material, and the second panel 220 is made of ABS material (acrylonitrile-butadiene-styrene plastic). In other embodiments, the first panel 210 and the second panel 220 may also be made of two other different materials.

[0060] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the outer diameter of the first limiting structure 201 is smaller than the diameter of the through hole 101. This creates a gap between the first limiting structure 201 and the inner wall of the through hole 101. This gap can serve as an injection port for the edge-sealing material; that is, the edge-sealing material can be injected between the glass 100 and the decorative panel 200 through the gap between the first limiting structure 201 and the inner wall of the through hole 101.

[0061] In some embodiments, an injection gate 102 is provided between the first limiting structure 201 and the through hole 101.

[0062] Please refer to Figure 7 and Figure 8 As shown, where, Figure 7 This is a schematic diagram of injection molding in related technologies. Figure 8 for Figure 6 This is a schematic diagram of the glass edging assembly 10 in the illustrated embodiment during injection molding. In related technologies, the injection gate 102 is located at the edge of the edging 300. After the injection molding equipment 30 injects the edging material, it takes a long time for the edging material to flow from the right side to the left side of the figure, resulting in a longer injection molding time. In the embodiments of this application, as... Figure 8 As shown, by arranging the injection gate 102 at the through hole 101, on the one hand, the injection gate 102 can be moved away from the A side of the edge banding 300, which improves the spray pattern problem and enhances the product appearance; on the other hand, after the edge banding material is injected by the injection molding equipment 30, the edge banding material can flow from the middle to both sides, which greatly reduces the injection time and improves production efficiency.

[0063] In some embodiments, such as Figure 2 , Figure 4 As shown, there are multiple through holes 101, and the number of first limiting structures 201 is equal to the number of through holes 101. Each of the multiple first limiting structures 201 corresponds to one of the multiple through holes 101. Correspondingly, there are also multiple second limiting structures 23 on the injection mold, each corresponding to one of the multiple first limiting structures 201. Each second limiting structure 23 cooperates with a corresponding first limiting structure 201. This provides better support and limiting for the trim panel 200, thus better maintaining the flatness of the trim panel 200 during injection molding and further reducing the possibility of appearance defects in the trim panel 200. In addition, when the gap between the inner wall of the first limiting structure 201 and the through hole 101 is used as the injection port for the edge trimming material, multiple first limiting structures 201 and multiple corresponding through holes 101 can be used to construct multiple injection ports. Injecting edge trimming material through multiple injection ports helps to increase the injection speed of edge trimming material, thereby improving production efficiency. It also helps to improve the uniformity of edge trimming material distribution, so that the formed edge trimming 300 has better thickness uniformity.

[0064] In some embodiments, such as Figure 2 , Figure 4 As shown, the glass edging assembly 10 also includes a plurality of studs 400, which are disposed on the side of the glass 100 away from the trim panel 200. The studs 400 are used for connection with external sheet metal parts. That is, the glass edging assembly 10 can be connected to external sheet metal parts through the studs 400, thereby realizing the installation between the glass edging assembly 10 and the external structure. For example, the glass 100 can be a side window glass 100 of a vehicle, in which case the external sheet metal parts can be vehicle body sheet metal.

[0065] In some embodiments, glass 100 may be tempered glass, laminated glass, semi-tempered glass, smart glass, etc.

[0066] In some embodiments, refer to Figure 9 As shown, the first limiting structure 201 can be a columnar structure, the injection mold 20 includes an upper mold 21 and a lower mold 22, and the second limiting structure 23 is a groove, in which the first limiting structure 201 is engaged. For example, the groove can be a circular groove, an elliptical groove, etc.

[0067] It is understandable that when there are multiple second limiting structures 23, some of the second limiting structures 23 can be circular grooves, some can be elliptical grooves, and others can be grooves of other shapes. Among them, the circular grooves can play a primary positioning and primary limiting role, while the elliptical grooves and other shaped grooves can play an auxiliary positioning and auxiliary limiting role.

[0068] In some embodiments, refer to Figure 10 As shown, the first limiting structure 201 can be a hollow column, and the second limiting structure 23 can be a columnar structure. When the first limiting structure 201 and the second limiting structure 23 are combined, the second limiting structure 23 passes through the first limiting structure 201.

[0069] In some embodiments, please refer to Figures 1 to 6 The glass edging assembly 10 includes a glass 100, a decorative panel 200, and an edging 300. Specifically, the edging 300 is disposed between the glass 100 and the decorative panel 200, and is formed by injection molding to connect the glass 100 and the decorative panel 200 as a whole. The glass 100 has a through hole 101, and the decorative panel 200 has a first limiting structure 201, which passes through the through hole 101 and is used to cooperate with a second limiting structure 23 on the injection mold. The end of the first limiting structure 201 away from the decorative panel 200 protrudes from the surface of the glass 100 on the side away from the decorative panel 200, and the outer diameter of the first limiting structure 201 is smaller than the diameter of the through hole 101.

[0070] The glass edging assembly 10 in this embodiment can be manufactured by integral injection molding. The injection mold used during injection molding is equipped with a second limiting structure 23. Specifically, the glass 100 and the decorative panel 200 can be placed in the injection mold. After placement, the first limiting structure 201 on the decorative panel 200 passes through the through hole 101 in the glass 100 and cooperates with the second limiting structure 23. Then, edging material is injected into the injection mold. After the edging material cools and solidifies, an edging 300 is formed, connecting the glass 100 and the decorative panel 200 as a whole. During the injection and cooling of the edging material, the second limiting structure 23, through its cooperation with the first limiting structure 201, consistently provides support and limitation for the decorative panel 200. This support and limitation can counteract the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the decorative panel 200's appearance and reducing the possibility of appearance defects. In addition, the glass edging assembly 10 in this embodiment does not require inserts during the manufacturing process, thus reducing manufacturing costs and improving production efficiency.

[0071] Furthermore, the end of the first limiting structure 201 away from the trim panel 200 protrudes from the surface of the glass 100 on the side away from the trim panel 200. This arrangement gives the first limiting structure 201 a certain height, thus enhancing its support and limiting effect on the trim panel 200 when it cooperates with the second limiting structure 23. On the other hand, the fact that the end of the first limiting structure 201 away from the trim panel 200 protrudes from the surface of the glass 100 on the side away from the trim panel 200 also prevents the edge trim material from contacting and sticking to the second limiting structure 23. This reduces the difficulty of demolding, allowing the finished glass edge trim assembly 10 to be removed from the injection mold more easily.

[0072] Furthermore, the outer diameter of the first limiting structure 201 is smaller than the diameter of the through hole 101, thus forming a gap between the first limiting structure 201 and the inner wall of the through hole 101. This gap can serve as an injection port for the edge trimming material, which can be injected between the glass 100 and the decorative panel 200 through the gap between the inner wall of the first limiting structure 201 and the through hole 101.

[0073] The second aspect of this application provides a method for manufacturing a glass edging assembly 10, such as... Figure 11 As shown, the manufacturing method includes:

[0074] Step S100: Provide glass 100 and decorative panel 200, place glass 100 and decorative panel 200 in injection mold, wherein glass 100 is provided with through hole 101, decorative panel 200 is provided with first limiting structure 201, injection mold has second limiting structure 23, first limiting structure 201 passes through through hole 101 and cooperates with second limiting structure 23;

[0075] Step S200: Inject edge trimming material into the injection mold. After the edge trimming material cures, it forms an edge trimming 300 and connects the glass 100 and the decorative panel 200 into one piece.

[0076] In the manufacturing method of the glass edging assembly 10 in this embodiment, during the injection of the edging material and the cooling process of the edging material, the second limiting structure 23, in cooperation with the first limiting structure 201, consistently provides support and limitation for the decorative panel 200. This support and limitation can counteract the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the decorative panel 200 and reducing the possibility of appearance defects. Furthermore, the glass edging assembly 10 does not require inserts during manufacturing, thus reducing manufacturing costs and improving production efficiency.

[0077] In some embodiments, the outer diameter of the first limiting structure 201 is smaller than the diameter of the through hole 101;

[0078] The process of injecting edge-sealing material into the injection mold includes:

[0079] The edging material is injected between the glass 100 and the decorative panel 200 through the gap between the first limiting structure 201 and the through hole 101.

[0080] In other words, the gap between the first limiting structure 201 and the inner wall of the through hole 101 can be used as the injection port for the edge trimming material, so that the edge trimming material can be injected between the glass 100 and the decorative panel 200.

[0081] In some embodiments, the number of through holes 101 is multiple, the number of first limiting structures 201 is equal to the number of through holes 101, and multiple first limiting structures 201 and multiple through holes 101 are arranged in a one-to-one correspondence, with a gap formed between each first limiting structure 201 and the corresponding through hole 101.

[0082] The process of injecting the edging material between the glass 100 and the decorative panel 200 through the gap between the first limiting structure 201 and the through hole 101 includes:

[0083] By injecting edge-sealing material simultaneously through multiple gaps, the edge-sealing material fills the space between the glass 100 and the decorative panel 200.

[0084] In this embodiment, multiple first limiting structures 201 and multiple corresponding through holes 101 can form multiple injection ports. Injecting the edge binding material through multiple injection ports helps to increase the injection speed of the edge binding material, thereby improving production efficiency. In addition, it also helps to improve the distribution uniformity of the edge binding material, so that the formed edge binding 300 has better thickness uniformity.

[0085] An embodiment of the third aspect of this application provides a vehicle that includes the glass cladding assembly 10 of any of the above embodiments.

[0086] In this embodiment of the vehicle, the glass edging assembly 10 can be manufactured by integral injection molding. The injection mold used during injection molding is equipped with a second limiting structure 23. Specifically, the glass 100 and the trim panel 200 can be placed in the injection mold. After placement, the first limiting structure 201 on the trim panel 200 passes through the through hole 101 in the glass 100 and cooperates with the second limiting structure 23. Then, edging material is injected into the injection mold. After the edging material cools and solidifies, an edging 300 is formed, connecting the glass 100 and the trim panel 200 as a whole. During the injection and cooling of the edging material, the second limiting structure 23, through its cooperation with the first limiting structure 201, consistently limits the trim panel 200. This limiting effect can counteract the shrinkage force generated during the cooling of the edging material, thereby maintaining the flatness of the trim panel 200's appearance and reducing the possibility of appearance defects in the trim panel 200. In addition, the glass edging assembly 10 in this embodiment does not require inserts during the manufacturing process, thus reducing manufacturing costs and improving production efficiency.

[0087] 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.

[0088] 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.
