Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a glass assembly and its preparation method, and a vehicle. Background Technology

[0002] In the automotive industry, the edge-wrapping structure of glass assemblies offers advantages such as improved sealing and reduced noise, while the insert structure of glass assemblies offers advantages such as improved assembly efficiency on vehicle production lines, shorter assembly cycles, and increased strength. However, due to the influence of the insert structure, it is difficult for glass assemblies to simultaneously achieve both the performance of flexible production and the resistance to deformation of the edge-wrapping structure. Summary of the Invention

[0003] This application provides a glass assembly with high production flexibility and a non-deformable edge structure, as well as a method for its preparation and a vehicle.

[0004] On one hand, this application provides a glass assembly, including:

[0005] Glass body;

[0006] The edging structure includes a first edging portion and a second edging portion that are bent and connected.

[0010] In one possible embodiment, the extension dimension of the second insert portion is greater than or equal to 7 mm.

[0011] In one possible embodiment, the thickness of the second sub-edge portion is greater than or equal to 2 mm and less than or equal to 6.5 mm.

[0012] In one possible embodiment, the plastic insert further includes a fourth surface connected to the concave bevel, the fourth surface being spaced from the glass body at a distance greater than or equal to 2 mm and less than or equal to 3.5 mm.

[0013] In one possible embodiment, the metal insert further includes a third insert portion bent and connected to the end of the first insert portion away from the second insert portion. The third insert portion includes a third sub-insert portion and a base portion. The third sub-insert portion is connected between the base portion and the first insert portion. The distance between the base portion and the glass body is smaller than the distance between the third sub-insert portion and the glass body. The first sub-edge portion also wraps around the side of the base portion away from the third sub-insert portion and the side of the base portion away from the glass body.

[0014] In one possible embodiment, the distance between the surface of the support portion facing away from the glass body and the surface of the third sub-insert portion facing away from the glass body is greater than or equal to 1 mm, the extension dimension of the support portion is less than or equal to 1 mm, the distance between the support portion and the glass body is greater than or equal to 1 mm, and the first edge portion wrapping around the side of the support portion facing away from the third sub-insert portion by a dimension greater than or equal to 0.5 mm.

[0015] In one possible embodiment, the second insert portion is connected to the first edge portion, the second edge portion includes a third sub-edge portion and a fourth sub-edge portion that are bent and connected, the third sub-edge portion is connected between the first edge portion and the fourth sub-edge portion, the fourth sub-edge portion has the concave slope, the first insert portion and the third sub-edge portion are spaced apart, and the plastic insert is connected between the fourth sub-edge portion, the third sub-edge portion and the end of the first edge portion near the third sub-edge portion.

[0016] In one possible embodiment, the plastic insert includes a fifth surface and a sixth surface disposed adjacent to each other, the fifth surface being connected to the third sub-edge portion, the second insert portion including a seventh surface being connected to the first edge portion, the sixth surface being flush with the seventh surface and connected to one end of the first edge portion near the third sub-edge portion.

[0017] In one possible embodiment, one of the plastic insert and the metal insert includes a boss, and the other of the plastic insert and the metal insert includes a groove, wherein the surface of the boss is connected to the groove wall of the groove.

[0018] On the other hand, this application also provides a vehicle including a body sheet and the glass assembly, the glass assembly being mounted on the body sheet.

[0019] In another aspect, this application also provides a method for preparing a glass assembly, the method comprising: integrating the plastic insert onto the metal insert by at least one of integral injection molding or mechanical connection to prepare the insert structure.

[0020] In one possible embodiment, the method further includes: placing the glass body and the insert structure in a mold; and forming the edging structure between the glass body and the insert structure by injection molding.

[0021] The glass assembly provided in this application includes a glass body, an edge-sealing structure, and an insert structure. The edge-sealing structure includes a first edge-sealing portion and a second edge-sealing portion that are bent and connected. The end of the first edge-sealing portion away from the second edge-sealing portion wraps around the edge of the glass body. The second edge-sealing portion extends relative to the first edge-sealing portion towards the side opposite to the glass body. One of the first edge-sealing portion and the second edge-sealing portion has a concave bevel. The insert structure is located on the side of the edge-sealing structure opposite to the glass body. The insert structure includes a metal insert and a plastic insert. The metal insert includes a first insert portion and a second insert portion that are bent and connected. The first insert portion connects one of the first edge-sealing portion and the second edge-sealing portion through a plastic insert. The second insert portion connects the first edge-sealing portion and the second edge-sealing portion. Therefore, in general, the design of the metal insert can ensure the basic strength of the glass assembly. The design of the plastic insert between the first insert part of the metal insert and the edge-wrapping structure allows the size of the first or second edge-wrapping part with the concave slope to be reduced, so that the edge-wrapping structure is not easily deformed. In addition, the design of the plastic insert between the first insert part and the edge-wrapping structure also eliminates the need for the first insert part to form a corresponding recessed area due to the concave slope of the first or second edge-wrapping part. This eliminates the need for the mold for producing the glass assembly to have a slider with a corresponding recessed area. This makes the insertion of the insert structure into the mold more flexible and is conducive to the automated production of the glass assembly. Attached Figure Description

Detailed Implementation

[0039] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0040] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0041] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, an assembly or device comprising one or more components is not limited to the one or more components listed, but may optionally also include one or more components not listed but inherent to the exemplified product, or one or more components that it should have based on the described function.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a glass assembly 100 provided in an embodiment of this application. Figure 2 This is another structural schematic diagram of the glass assembly 100 provided in an embodiment of this application. The glass assembly 100 includes a glass body 10, an edging structure 20, and an insert structure 30.

[0043] The glass body 10 can be single-layer glass, laminated glass, or tempered glass. In vehicle 1000 industry applications, the glass body 10 can serve as one of the following: windshield, side window, rear windshield, sunroof, etc. The glass body 10 includes a first surface 101, a second surface 102, and a third surface 103, which are sequentially bent and connected. The first surface 101 and the second surface 102 are arranged opposite to each other. In vehicle 1000 industry applications, one of the first surface 101 and the second surface 102 can face the interior of the vehicle 1000, and the other can face the exterior of the vehicle 1000.

[0044] The edging structure 20 is used to wrap around the glass body 10. In one possible embodiment, the edging structure 20 can wrap around the circumference of the edge of the glass body 10. The edging structure 20 includes a first edging portion 201 and a second edging portion 202 that are bent and connected. This application does not specifically limit the bending angle between the first edging portion 201 and the second edging portion 202, and it can be designed according to actual requirements. In one possible embodiment, the bending angle between the first edging portion 201 and the second edging portion 202 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the first edging portion 201 and the second edging portion 202 can be connected by an arc bend. In the embodiments of this application, the bending angle between the first edging portion 201 and the second edging portion 202 can be referred to the appendix. Figure 1 , Figure 2As shown in Figure α, the first edge-wrapping portion 201, at one end away from the second edge-wrapping portion 202, wraps around the edge of the glass body 10. In one possible embodiment, the end of the first edge-wrapping portion 201 away from the second edge-wrapping portion 202 may wrap around the edges of the first surface 101, the second surface 102, and the third surface 103. The second edge-wrapping portion 202 extends relative to the first edge-wrapping portion 201 toward the side opposite to the glass body 10. In this embodiment, the specific extension direction of the second edge-wrapping portion 202 can be referred to the attached figure. Figure 1 , Figure 2 The X direction is shown in the diagram.

[0045] At least one of the first edge portion 201 and the second edge portion 202 has a concave bevel surface 21. In one possible embodiment, as... Figure 1 As shown, the first edge-wrapping portion 201 may have a concave slope 21. In this embodiment, the concave slope 21 of the first edge-wrapping portion 201 means that when the insert structure 30 is a single-material plastic insert structure, the connection between it and the first edge-wrapping portion 201 requires the corresponding area of ​​the single-material plastic insert structure to have a relatively wide width. Conversely, when the insert structure 30 is a single-material metal insert structure, the connection between it and the first edge-wrapping portion 201 requires the corresponding area of ​​the single-material metal insert structure to be concave inwards. However, the single-material plastic insert structure has low strength, and during the injection molding process to prepare the edge-wrapping structure 20, it is prone to deformation, such as warping or shrinkage. While the single-material metal insert structure can guarantee strength requirements, during the injection molding process to prepare the edge-wrapping structure 20, the mold for preparing the glass assembly 100 needs to be equipped with a slider corresponding to the concave area of ​​the single-material metal insert structure. This makes it impossible to flexibly place the single-material metal insert structure in the mold of the glass assembly 100, which is not conducive to automated production. In another possible embodiment, such as Figure 2 As shown, the second edge portion 202 may have a concave slope 21. When the second edge portion 202 has a concave slope 21, its connection with the single-material plastic insert structure and the single-material metal insert structure has the same problem as when the first edge portion 201 has a concave slope 21.

[0046] The insert structure 30 is used to support the glass body 10 and the edging structure 20, improve the strength of the glass assembly 100, and connect the glass assembly 100 to the vehicle body. The insert structure 30 is at least partially embedded within the edging structure 20. In other words, at least a portion of the insert structure 30 is located on the side of the edging structure 20 opposite to the glass body 10. It is understood that the insert structure 30 is connected to the glass body 10 through the edging structure 20. In one possible embodiment, the glass assembly 100 can be fabricated between the glass body 10 and the insert structure 30 via injection molding of the edging structure 20. The insert structure 30 includes a metal insert 301 and a plastic insert 302. The insert structure 30 of this application can be understood as a dual-material insert structure. The metal insert 301 refers to an insert made of metal (including single metals, alloys, etc.). The plastic insert 302 refers to an insert made of plastic. The plastic insert 302 is connected to one side of the metal insert 301. The connection methods between the plastic insert 302 and the metal insert 301 include, but are not limited to, integral connection, adhesive bonding, or snap-fit.

[0047] The metal insert 301 includes a first insert portion 310 and a second insert portion 311 that are bent and connected. This application does not specifically limit the bending angle between the first insert portion 310 and the second insert portion 311; it can be designed according to actual requirements. In one possible embodiment, the bending angle between the first insert portion 310 and the second insert portion 311 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the first insert portion 310 and the second insert portion 311 can be connected by an arc-shaped bend. Optionally, the bending angle between the first insert portion 310 and the second insert portion 311 is less than or equal to the bending angle between the first edge portion 201 and the second edge portion 202. In the embodiments of this application, the bending angle between the first insert portion 310 and the second insert portion 311 can be referred to the appendix. Figure 1 , Figure 2 As shown in Figure β. The orthographic projection of the bent connection between the first insert portion 310 and the second insert portion 311 onto the edging structure 20 can lie on the one of the first edging portion 201 and the second edging portion 202 that does not have the concave bevel 21. This is understandable, as... Figure 1 As shown, in an embodiment where the first edge portion 201 has a concave bevel 21, the orthographic projection of the bend connection between the first insert portion 310 and the second insert portion 311 onto the edge structure 20 can be located in the second edge portion 202; as Figure 2As shown, in the embodiment where the second edge portion 202 has a concave bevel 21, the orthographic projection of the bent connection between the first insert portion 310 and the second insert portion 311 onto the edge structure 20 can be located on the first edge portion 201. This facilitates the connection between the bent connection between the first insert portion 310 and the second insert portion 311 and the bent connection between the first edge portion 201 and the second edge portion 202 via the plastic insert 302, thereby reducing the deformation of the bent connection between the first edge portion 201 and the second edge portion 202 during the injection molding process and improving the strength of the bent connection between the first edge portion 201 and the second edge portion 202.

[0048] The first insert portion 310 connects to one of the first edge-binding portions 201 and the second edge-binding portion 202 having the concave slope 21 via the plastic insert 302. The second insert portion 311 connects to the other of the first edge-binding portion 201 and the second edge-binding portion 202. It can be understood that the first insert portion 310 connects to one edge-binding portion of the first edge-binding portion 201 and the second edge-binding portion 202 having the concave slope 21 via the plastic insert 302, and the second insert portion 311 directly or indirectly connects to the other edge-binding portion of the first edge-binding portion 201 and the second edge-binding portion 202. In other words, as... Figure 1 As shown, in the embodiment where the first edge portion 201 has a concave slope 21, the plastic insert 302 is connected between the first insert portion 310 and the first edge portion 201, and the second insert portion 311 can be directly connected to the second edge portion 202. In this embodiment, in the embodiment where the first edge portion 201 has a concave slope 21, the second insert portion 311 is directly connected to the second edge portion 202. Of course, in other possible embodiments, the second insert portion 311 can also be indirectly connected to the second edge portion 202, that is, the second insert portion 311 can be connected to the second edge portion 202 through another plastic insert. Figure 2 As shown, in an embodiment where the second edge portion 202 has a concave slope 21, the plastic insert 302 is connected between the first insert portion 310 and the second edge portion 202, and the second insert portion 311 can be directly connected to the first edge portion 201. In this embodiment, in an embodiment where the second edge portion 202 has a concave slope 21, the second insert portion 311 is indirectly connected to the first edge portion 201. Of course, in other possible embodiments, the second insert portion 311 can also be indirectly connected to the first edge portion 201, that is, the second insert portion 311 can be connected to the first edge portion 201 through another plastic insert.

[0049] In the following embodiments, unless otherwise specified, one of the first edge-binding portion 201 and the second edge-binding portion 202 includes a concave slope 21, while the other does not. The first insert portion 310 is positioned opposite and spaced apart from the edge-binding portion 201 and the second edge-binding portion 202 that has the concave slope 21. The second insert portion 311 is in contact with the edge-binding portion 201 and the second edge-binding portion 202 that does not have the concave slope 21.

[0050] Of course, in other possible embodiments, in embodiments where the first edge portion 201 has a concave slope 21 and the second edge portion 202 also has a concave slope 21, the plastic insert 302 may include a first plastic insert and a second plastic insert. The first insert portion 310 connects one of the first edge portion 201 and the second edge portion 202 through the first plastic insert, and the second edge portion 202 connects the other of the first edge portion 201 and the second edge portion 202 through the second plastic insert.

[0051] The glass assembly 100 provided in this application includes a glass body 10, an edge-sealing structure 20, and an insert structure 30. The edge-sealing structure 20 includes a first edge-sealing portion 201 and a second edge-sealing portion 202 that are bent and connected. The first edge-sealing portion 201 wraps around the edge of the glass body 10 at one end away from the second edge-sealing portion 202. The second edge-sealing portion 202 extends relative to the first edge-sealing portion 201 towards the side away from the glass body 10. One of the first edge-sealing portion 201 and the second edge-sealing portion 202 has a concave bevel 21. The insert structure 30 is located on the side of the edge-sealing structure 20 away from the glass body 10. The insert structure 30 includes a metal insert 301 and a plastic insert 302. The metal insert 301 includes a first insert portion 310 and a second insert portion 311 that are bent and connected. The first insert portion 310 connects to one of the first edge-sealing portion 201 and the second edge-sealing portion 202 via the plastic insert 302. The second insert portion 311 connects to the first edge-sealing portion 201 and the second edge-sealing portion 202. The other of the first edge portion 201 and the second edge portion 202, therefore, in general, the design of the metal insert 301 can ensure the basic strength of the glass assembly 100. The design of the plastic insert 302 between the first insert portion 310 of the metal insert 301 and the edge structure 20 allows the size of the first edge portion 201 or the second edge portion 202 with the concave slope 21 to be reduced, so that the edge structure 20 is not easily deformed. In addition, the design of the plastic insert 302 between the first insert portion 310 and the edge structure 20 also allows the first insert portion 310 to not need to form a corresponding recessed area due to the concave slope 21 of the first edge portion 201 or the second edge portion 202. Therefore, the mold for producing the glass assembly 100 does not need to be equipped with a slider with a corresponding recessed area. This makes the insertion structure 30 more flexible in the mold and is conducive to the automated production of the glass assembly 100.

[0052] In one possible embodiment, such as Figure 3 As shown, the second insert portion 311 is connected to the second edge portion 202. In this embodiment, the second insert portion 311 and the second edge portion 202 are directly connected. Optionally, the second edge portion 202 is directly formed on the second insert portion 311. The first edge portion 201 includes a first sub-edge portion 210 and a second sub-edge portion 211 that are bent and connected. Similarly, this application does not specifically limit the bending angle between the first sub-edge portion 210 and the second sub-edge portion 211, and it can be designed according to actual requirements. In one possible embodiment, the bending angle between the first sub-edge portion 210 and the second sub-edge portion 211 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the first sub-edge portion 210 and the second sub-edge portion 211 can be connected by an arc bend. In this embodiment, the bending angle between the first edge portion 201 and the second edge portion 202 can be referred to the attached figure. Figure 3As shown in Figure γ, the first sub-edge portion 210 wraps around the edge of the glass body 10, and the side of the first sub-edge portion 210 facing away from the glass body 10 has the concave slope 21. The second sub-edge portion 211 connects the second sub-edge portion 202 and the first sub-edge portion 210. The first sub-edge portion 210 can wrap around the edges of the first surface 101, the second surface 102, and the third surface 103 of the glass body 10. The side of the first sub-edge portion 210 facing away from the glass body 10, and the surface connected to the second sub-edge portion 211, forms the concave slope 21. In other words, the first sub-edge portion 210, the second sub-edge portion 211, and the second sub-edge portion 202 enclose a concave space. The first insert portion 310 includes a smoothly connected first sub-insert portion 3101 and a second sub-insert portion 3102. The first sub-insert portion 3101 is connected to the side of the first sub-edge portion 210 facing away from the glass body 10. The second sub-insert portion 3102 is spaced apart from the second sub-edge portion 211, and the plastic insert 302 is connected between the concave inclined surface 21, the second sub-insert portion 3102, the second sub-edge portion 211, and the end of the second edge portion 202 near the second sub-edge portion 211. In this embodiment, the smooth connection between the first sub-insert portion 3101 and the second sub-insert portion 3102 can be understood as the absence of bends between the first sub-insert portion 3101 and the second sub-insert portion 3102. This allows the first insert portion 310 to be connected to the first edge portion 201 not by bending, but by direct connection and through the plastic insert 302. Specifically, the first sub-insert portion 3101 is directly connected to the first sub-edge portion 210, and the second sub-insert portion 3102 is connected to the second sub-edge portion 211 through the plastic insert 302. This ensures the smoothness of the back side of the first insert portion 310, making it easier to manually or automatically place the insert structure 30 into the glass assembly 100 mold, thus improving the flexibility of manufacturing the glass assembly 100.

[0053] The dual-insert structure 30 of the glass assembly 100 provided in this embodiment is suitable for application scenarios where the side surface of the edge-wrapping structure 20, i.e. the surface of the second sub-edge-wrapping portion 211, has certain shrinkage and deformation requirements. By forming a plastic insert 302 on the second sub-insert portion 3102 of the metal insert 301, and forming the second sub-edge-wrapping portion 211 on the side of the plastic insert 302 away from the second sub-insert portion 3102, the thickness of the second sub-edge-wrapping portion 211 is reduced while ensuring the strength of the insert structure 30. This makes the surface of the second sub-edge-wrapping portion 211 less susceptible to shrinkage due to temperature during injection molding of the edge-wrapping structure 20. Furthermore, the back side of the metal insert 301 has no recessed design, resulting in high production flexibility.

[0054] Please refer to Figure 4 and Figure 5The plastic insert 302 includes a first surface 320 and a second surface 321 disposed adjacent to each other. Both the first surface 320 and the second surface 321 are planar. The first surface 320 and the second surface 321 are bent together, and the bending angle between the first surface 320 and the second surface 321 is equal to the bending angle between the first edge portion 201 and the second edge portion 202. The first surface 320 is connected to the second sub-edge portion 211. It is understood that the second sub-edge portion 211 is formed on the first surface 320 of the plastic insert 302. The second insert portion 311 includes a third surface 3110. The third surface 3110 is planar. The third surface 3110 is connected to the second edge portion 202. It is understood that the second edge portion 202 is formed on the third surface 3110 of the second insert portion 311 of the metal insert 301. The second surface 321 is flush with the third surface 3110 and is connected to the end of the second edge portion 202 near the second sub-edge portion 211. The fact that the second surface 321 and the third surface 3110 are flush can be understood as the second surface 321 and the third surface 3110 having no difference in elevation in the extension direction.

[0055] In other words, in this embodiment, the connection between the surface of the plastic insert 302 and the surface of the second insert portion 311 of the metal insert 301 is flush and smooth. This solves the problems of marks and shrinkage on the surface of the edging structure 20.

[0056] Among them, such as Figure 5 As shown, the extension dimension of the second insert portion 311 is greater than or equal to 7 mm. The extension dimension of the second insert portion 311 can be referred to in the attached figure. Figure 5 As shown in Figure a. For example, the extension dimension of the second insert portion 311 can be 7mm, or 10mm, or 15mm, etc.

[0057] Since the second insert portion 311 is directly connected to the second edge-wrapping portion 202 in this embodiment, by making the extension dimension of the second insert portion 311 greater than or equal to 7mm, the supporting effect of the metal insert 301 on the glass body 10 and the edge-wrapping structure 20 can be improved. In addition, the extension dimension of the second insert portion 311 is relatively long, which can reduce the possibility of the edge-wrapping structure 20 warping upward.

[0058] Among them, such as Figure 5 As shown, the thickness of the second sub-edging portion 211 is greater than or equal to 2 mm and less than or equal to 6.5 mm. The thickness of the second sub-edging portion 211 can be referenced in the appendix. Figure 5As shown in Figure b. It is understood that the distance between the first surface 320 of the plastic insert 302 and the surface of the second sub-edge portion 211 on the side opposite to the plastic insert 302 is greater than or equal to 2 mm and less than or equal to 6.5 mm. Optionally, the thickness of the second sub-edge portion 211 is greater than or equal to 2 mm and less than or equal to 4 mm; or, the thickness of the second sub-edge portion 211 is greater than or equal to 4 mm and less than or equal to 6.5 mm. The thickness of the second sub-edge portion 211 can be uniform overall or can gradually change, for example, from the end of the second sub-edge portion 211 near the second edge portion 202 to the end of the second sub-edge portion 211 near the first sub-edge portion 210, the thickness gradually increases. When the thickness of the second sub-edge portion 211 gradually changes, in this embodiment, the thickness of the second sub-edge portion 211 is greater than or equal to 2 mm and less than or equal to 6.5 mm, which can be understood as the maximum thickness of the second sub-edge portion 211 being greater than or equal to 2 mm and less than or equal to 6.5 mm.

[0059] In this embodiment, the insert structure 30 is designed to include a metal insert 301 and a plastic insert 302. In this way, the thickness requirement of the second sub-edge portion 211 in the actual product can be slightly reduced. Even if the thickness of the second sub-edge portion 211 exceeds the requirement of less than 4mm in the relevant product, the shrinkage of the surface of the edge structure 20 can still meet the requirements.

[0060] Please refer to Figure 4 and Figure 5 The plastic insert 302 further includes a fourth surface 322. The fourth surface 322 is planar. The fourth surface 322 and the first surface 320 are bent together. The bending angle between the first surface 320 and the fourth surface 322 is equal to the bending angle between the first sub-edge portion 210 and the second sub-edge portion 211. The fourth surface 322 connects to the concave inclined surface 21. It is understood that at least a portion of the first sub-edge portion 210 is formed on the fourth surface 322 of the plastic insert 302. The distance between the fourth surface 322 and the glass body 10 is greater than or equal to 2 mm and less than or equal to 3.5 mm. The distance between the fourth surface 322 and the glass body 10 can be referenced in the appendix. Figure 5 As shown in c. For example, the distance between the fourth surface 322 and the glass body 10 can be 2mm, or 2.5mm, or 2.7mm, or 3mm, or 3.5mm, etc.

[0061] In this embodiment, since the fourth surface 322 of the plastic insert 302 is connected to the concave inclined surface 21 of the first sub-edge portion 210, a material flow channel needs to be formed between the fourth surface 322 and the glass body 10 during the process of forming the edge structure 20 through injection molding. Therefore, the distance between the fourth surface 322 and the glass body 10 is greater than or equal to 2 mm and less than or equal to 3.5 mm. This can avoid the situation where the surface of the edge structure 20 shrinks significantly when the width is too large, and can also ensure the smooth flow of material.

[0062] Furthermore, such as Figure 6 As shown, the metal insert 301 further includes a third insert portion 312 bent and connected to the end of the first insert portion 310 away from the second insert portion 311. The third insert portion 312 includes a third sub-insert portion 3120 and a support portion 3121, with the third sub-insert portion 3120 connected between the support portion 3121 and the first insert portion 310. The distance between the support portion 3121 and the glass body 10 is smaller than the distance between the third sub-insert portion 3120 and the glass body 10. The first sub-edge portion 210 also wraps around the side of the support portion 3121 opposite to the third sub-insert portion 3120 and the side of the support portion 3121 opposite to the glass body 10.

[0063] This application does not specifically limit the bending angle between the first insert portion 310 and the third insert portion 312, and it can be designed according to actual requirements. In one possible embodiment, the bending angle between the first insert portion 310 and the third insert portion 312 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the first insert portion 310 and the third insert portion 312 can be connected by an arc-shaped bend. The third sub-insert portion 3120 and the base portion 3121 are connected by a bend. This application does not specifically limit the bending angle between the third sub-insert portion 3120 and the base portion 3121, and it can be designed according to actual requirements. In one possible embodiment, the bending angle between the third sub-insert portion 3120 and the base portion 3121 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the third sub-insert portion 3120 and the base portion 3121 can be connected by an arc-shaped bend. The base portion 3121 is closer to the glass body 10 than the third sub-insert portion 3120. The third sub-insert portion 3120 is located on the side of the first sub-edge portion 210 that faces away from the glass body 10. The base portion 3121 is located between the glass body 10 and the first sub-edge portion 210.

[0064] In this embodiment, by providing a third insert portion 312, the third sub-insert portion 3120 of the third insert portion 312 can support the glass body 10 and the edge-binding structure 20. The support portion 3121 of the third insert portion 312 can prevent the edge-binding structure 20 from cracking when the end of the insert structure 30 is not coated with a base adhesive.

[0065] Among them, such as Figure 7 As shown, the distance between the surface of the support portion 3121 facing away from the glass body 10 and the surface of the third sub-insert portion 3120 facing away from the glass body 10 is greater than or equal to 0.5 mm, the extension dimension of the support portion 3121 is less than or equal to 1 mm, the distance between the support portion 3121 and the glass body 10 is greater than or equal to 1 mm, and the dimension of the first edge portion 201 wrapped around the side of the support portion 3121 facing away from the third sub-insert portion 3120 is greater than or equal to 0.5 mm.

[0066] The distance between the surface of the support portion 3121 facing away from the glass body 10 and the surface of the third sub-insert portion 3120 facing away from the glass body 10 can be referred to the attached figure. Figure 7 As shown in Figure d, the distance between the surface of the support portion 3121 facing away from the glass body 10 and the surface of the third sub-insert portion 3120 facing away from the glass body 10 can also be understood as the depth of the support portion 3121. The extension dimensions of the support portion 3121 can be referred to in the appendix. Figure 7 As shown in Figure e. The extension dimension of the support portion 3121 can also be understood as the width of the support portion 3121. The distance between the support portion 3121 and the glass body 10 can be referred to the attached figure. Figure 7 As shown in Figure g. The dimensions of the first edging portion 201 enclosing the side of the support portion 3121 opposite to the third sub-insert portion 3120 can be referred to in the appendix. Figure 7 As shown in f. The dimension of the first edging portion 201 that wraps around the side of the base portion 3121 away from the third sub-insert portion 3120 can also be understood as the edging thickness of the outer side of the base portion 3121.

[0067] By designing the depth of the support portion 3121, the width of the support portion 3121, the distance between the support portion 3121 and the glass body 10, and the thickness of the outer edge of the support portion 3121, the effect of preventing the end cracking of the metal insert 301 can be improved.

[0068] In another possible embodiment, such as Figure 8As shown, the second insert portion 311 is connected to the first edge-wrapping portion 201. In this embodiment, the second insert portion 311 is directly connected to the first edge-wrapping portion 201. Optionally, the first edge-wrapping portion 201 is directly formed on the second insert portion 311. The second edge-wrapping portion 202 includes a third sub-edge-wrapping portion 220 and a fourth sub-edge-wrapping portion 221 that are bent and connected. Similarly, this application does not specifically limit the bending angle between the third sub-edge-wrapping portion 220 and the fourth sub-edge-wrapping portion 221, and it can be designed according to actual requirements. In one possible embodiment, the bending angle between the third sub-edge-wrapping portion 220 and the fourth sub-edge-wrapping portion 221 can be greater than 90° and less than 180°. To avoid forming sharp corner areas, the third sub-edge-wrapping portion 220 and the fourth sub-edge-wrapping portion 221 can be connected by an arc bend. In this embodiment, the bending angle between the third sub-edge-wrapping portion 220 and the fourth sub-edge-wrapping portion 221 can be referred to the attached figure. Figure 8 As shown in λ. The third sub-edge portion 220 is connected between the first edge portion 201 and the fourth sub-edge portion 221, and the fourth sub-edge portion 221 has the concave inclined surface 21. In other words, the fourth sub-edge portion 221, the third sub-edge portion 220, and the first edge portion 201 form a concave space. In this embodiment, because the fourth sub-edge portion 221 has the concave inclined surface 21, the thickness of the third sub-edge portion 220 of the edge structure 20 prepared by injection molding will be relatively large. In related technologies, single-material metal insert structures cannot be moved upward to reduce the thickness of the third sub-edge portion 220, and the surface of the edge structure 20 prepared by injection molding is prone to shrinkage and deformation. However, the double-material insert structure 30 provided in this application embodiment can reduce the thickness of the third edge portion while taking into account strength, thereby reducing the surface shrinkage and deformation of the edge structure 20. Specifically, the first insert portion 310 and the third sub-edge portion 220 are spaced apart. The plastic insert 302 is connected between the fourth sub-edge portion 221, the third sub-edge portion 220, and the end of the first edge portion 201 near the third sub-edge portion 220.

[0069] The dual-insert structure 30 of the glass assembly 100 provided in this embodiment is suitable for application scenarios where the top surface of the edge-wrapping structure 20, i.e. the surface of the third sub-edge-wrapping portion 220, has certain shrinkage and deformation requirements. By forming a plastic insert 302 on the first insert portion 310 of the metal insert 301, and forming the third sub-edge-wrapping portion 220 on the side of the plastic insert 302 away from the first insert portion 310, the thickness of the third sub-edge-wrapping portion 220 is reduced while ensuring the strength of the insert structure 30. This makes the surface of the third sub-edge-wrapping portion 220 less susceptible to shrinkage due to temperature during injection molding of the edge-wrapping structure 20. Furthermore, the metal insert 301 has no recessed design on the back side, resulting in high production flexibility.

[0070] Please refer to Figure 8 and Figure 9 The plastic insert 302 includes a fifth surface 323 and a sixth surface 324 disposed adjacently. Both the fifth surface 323 and the sixth surface 324 are planar. The fifth surface 323 and the sixth surface 324 are bent together, and the bending angle between the fifth surface 323 and the sixth surface 324 is equal to the bending angle between the first edge portion 201 and the second edge portion 202. The fifth surface 323 is connected to the third sub-edge portion 220. It is understood that the third sub-edge portion 220 is formed on the fifth surface 323 of the plastic insert 302. The second insert portion 311 includes a seventh surface 3112. The seventh surface 3112 is planar. The seventh surface 3112 is connected to the first edge portion 201. It is understood that the first edge portion 201 is formed on the seventh surface 3112 of the second insert portion 311 of the metal insert 301. The sixth surface 324 is flush with the seventh surface 3112 and connects to the end of the first edge portion 201 near the third sub-edge portion 220. The fact that the sixth surface 324 and the seventh surface 3112 are flush can be understood as meaning that the sixth surface 324 and the seventh surface 3112 have no difference in elevation in the extending direction.

[0071] In other words, in this embodiment, the connection between the surface of the plastic insert 302 and the surface of the second insert portion 311 of the metal insert 301 is flush and smooth. This solves the problems of marks and shrinkage on the surface of the edging structure 20.

[0072] In addition, please refer to Figures 10 to 12 One of the plastic insert 302 and the metal insert 301 includes a boss, and the other of the plastic insert 302 and the metal insert 301 includes a groove. The surface of the boss is connected to the groove wall. This application does not specifically limit the number of bosses in one of the plastic inserts 302 and the metal insert 301, or the number of grooves in the other of the plastic inserts 302 and the metal insert 301. The following embodiments use one boss and one corresponding groove as an example.

[0073] In one possible embodiment, such as Figure 11 As shown, the plastic insert 302 includes a boss. The metal insert 301 includes a groove. The shape of the boss includes, but is not limited to, a circle, a square, or an oblong shape. The shape of the groove matches the shape of the boss. This allows the plastic insert 302 and the metal insert 301 to be tightly bonded together, thereby improving the reliability of the glass assembly 100.

[0074] In another possible embodiment, such as Figure 12As shown, the plastic insert 302 includes a groove. The metal insert 301 includes a boss. The shape of the boss includes, but is not limited to, a circle, a square, or an oblong shape. The shape of the groove matches the shape of the boss. This allows the plastic insert 302 and the metal insert 301 to be tightly bonded together, thereby improving the reliability of the glass assembly 100.

[0075] In addition, such as Figure 13 As shown, this application also provides a vehicle 1000. The vehicle 1000 can be a sedan, bus, truck, tractor, special transport vehicle, or special vehicle, etc. In this embodiment, a sedan is used as an example.

The glass assembly 100 is mounted on the body sheet 200 by means including but not limited to mechanical connections such as welding, bonding, snap-fit ​​connections, and bolt connections.

[0076] like Figure 14 As shown, this application also provides a method for preparing a glass assembly 100.

[0081] S13: The edge-binding structure 20 is formed between the glass body 10 and the insert structure 30 by injection molding.

[0082] Steps S11, S12, and S13 are performed sequentially. In step S12, the method of placing the glass body 10 and the insert structure 30 into the mold includes, but is not limited to, manually placing the glass body 10 and the insert structure 30 into the mold respectively. In step S13, the temperature at which the edging structure 20 is formed between the glass body 10 and the insert structure 30 using the injection molding process can be approximately 200°C.
