Description

Technical Field

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

[0002] Modern cars use laminated glass technology for their windshields, as well as some side and rear windows. This type of glass is not a single-layer structure, but rather consists of two layers of high-strength glass with a transparent and resilient interlayer (usually polyvinyl butyral, or PVB) firmly bonded between them.

[0003] Automotive LCD dimming glass is a type of laminated glass, typically consisting of a PVB / EVA film and a dimming film sandwiched between two panes of glass. In related technologies, LCD dimming glass often requires further injection molding and edge sealing before assembly into the vehicle. However, injection-molded LCD dimming glass is prone to defects such as MURA (mud spots), which negatively impact the user experience. In LCD dimming glass, MURA refers to a display defect characterized by uneven brightness or color, typically manifesting as black spots, yellow spots, gray spots, cloud-like or striped marks, severely affecting the visual experience.

[0004] This relatively fragile sandwich structure is not unique to smart glass; some light-emitting glass, photovoltaic glass, and glass with electrical components in the sandwich structure may also be affected during the injection molding and edge-wrapping process. Summary of the Invention

[0017] In one embodiment, a first adhesive layer is provided between the first glass layer and the functional layer, and a second adhesive layer is provided between the second glass layer and the functional layer, wherein the thickness of the first adhesive layer is greater than or equal to the thickness of the second adhesive layer.

[0018] In one embodiment, the thickness of the first adhesive layer is greater than or equal to 0.5 mm.

[0019] In one embodiment, the edge of the glass assembly includes a mounting edge, the edging structure includes a mounting edging, the mounting edging covers the mounting edge, and a plurality of mounting members are spaced apart on the mounting edging.

Detailed Implementation

[0036] In the description of this application, it should be understood that if terms such as “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “bottom,” “inner,” and “outer” appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] Considering that the functional layer film in the glass interlayer after injection molding is prone to defects, which affect the user experience, this application provides a glass assembly and vehicle that can effectively reduce the probability of defects such as MURA black spots, improve the production quality of the glass assembly, and thus improve the user experience.

[0041] For details, please refer to Figure 1 One embodiment of this application provides a glass assembly 10, which may include a glass component 11 and an edge-sealing structure 12. Please refer to... Figure 2As shown, the glass assembly 11 includes a first glass layer 100, a functional layer 200, and a second glass layer 300 stacked together. An edge-binding structure 12 is connected to the edge of the glass assembly 11, and at least a portion of the edge-binding structure 12 covers the surface of the first glass layer 100 facing away from the functional layer 200. The edge-binding structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300; or, the width D of the overlapping area between the edge-binding structure 12 and the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 is less than or equal to 1 mm. It is worth noting that the aforementioned orthographic projection direction Y can be understood as the thickness direction of the glass assembly 11.

[0042] The glass assembly 10 described above, by setting that the edge-sealing structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300, or that the width D of the overlapping area between the edge-sealing structure 12 and the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 is less than or equal to 1 mm, can reduce the extrusion pressure of the edge-sealing structure 12 on the functional layer 200 during the injection molding process, thereby reducing the probability of defects such as MURA black spots.

[0043] It is worth noting that the first glass layer 100 described above in this application can be implemented as either the inner or outer glass of a vehicle. Correspondingly, when the first glass layer 100 can be implemented as the inner glass of a vehicle, the second glass layer 300 is the outer glass of the vehicle; when the first glass layer 100 can be implemented as the outer glass of a vehicle, the second glass layer 300 is the inner glass of the vehicle. Users can design according to their actual needs, and no limitation is made here.

[0044] Therefore, it is understandable that at least a portion of the edging structure 12 described above covers the surface of the first glass layer 100 on the side opposite to the functional layer 200, and can be correspondingly implemented such that at least a portion of the edging structure 12 covers the inner or outer glass of the vehicle.

[0045] Optionally, the aforementioned functional layer 200 may include, but is not limited to, a dimming film with dimming function. More specifically, the dimming film may be, but is not limited to, a liquid crystal film layer. Of course, the functional layer may also be implemented as a film layer with other functions, such as an image-capable film layer, a photovoltaic film layer, a light-emitting film layer, etc., or it may be a film layer containing electrical components or other functional film layers that are affected by pressure and temperature.

[0046] Preferably, the aforementioned functional layer 200 of this application is implemented as a dimming film with dimming function. The edge-sealing structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300. Alternatively, the width D of the overlapping area between the edge-sealing structure 12 and the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 is less than or equal to 1 mm. This significantly reduces the probability of defects such as MURA black spots, thus improving the dimming effect. In some embodiments, the aforementioned dimming film with dimming function can be implemented as an LC (Liquid Crystal) film. The substrate of the LC film can be, but is not limited to, a glass-based or flexible organic thin film substrate, such as PET (Polyethylene Terephthalate), PI (Polyimide), or TAC (Triallyl Cyanurate).

[0047] It should be noted that the edge-wrapping structure 12 described above in this application can be, but is not limited to, molded onto the edge of the glass assembly 11 by injection molding. The edge of the glass assembly 11 refers to the surface portion near the boundary 11a of the glass assembly 11. Please continue reading. Figure 2 In this application, the width D of the overlapping area between the edge-wrapping structure 12 and the functional layer 200 in the orthogonal projection direction Y of the second glass layer 300 is less than or equal to 1 mm. This can be understood as including three cases: the width D of the overlapping area is equal to 1 mm, greater than 0 and less than 1 mm, and equal to 0. Among them, the two cases of equal to 1 mm and greater than 0 and less than 1 mm both indicate that the projections of the edge-wrapping structure 12 and the functional layer 200 in the orthogonal projection direction Y of the second glass layer 300 overlap. Through product debugging and production verification, the inventors have found that when there is overlap and the overlap width is controlled within 1 mm, the degree of extrusion impact of the edge-wrapping structure 12 on the functional layer 200 during injection molding can be controlled to be small, or even negligible. Therefore, a small overlap width between the edge-wrapping structure 12 and the functional layer 200 is allowed.

[0048] In addition, taking into account the dimensional tolerance of the functional layer 200 and the placement tolerance of the glass assembly 11 during assembly, the setting that the width D of the overlapping area is less than or equal to 1 mm can improve the tolerance space for the edge-wrapping structure 12 during injection molding.

[0049] It should be noted that, in the aforementioned glass assembly 10, the overlap width D being equal to 0 refers to the situation where the edge-wrapping structure 12 and the functional layer 200 do not overlap after injection molding. Please also refer to... Figure 3Preferably, in some embodiments, the edging structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300, and the boundary 12a of the edging structure 12 and the boundary 200a of the functional layer 200 are flush with each other in the orthographic projection direction Y of the second glass layer 300. This can avoid the compression of the functional layer 200 by the edging injection material during the injection molding process in the orthographic projection direction Y of the second glass layer 300, while also improving the neatness and aesthetics of the structure, and strictly controlling the injection volume of the edging structure 12.

[0050] Please continue reading. Figure 4 More preferably, the edge-binding structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300, and there is a first preset distance D1 between the projection of the boundary 12a of the edge-binding structure 12 and the boundary 200a of the functional layer 200 in the orthographic projection direction Y of the second glass layer 300. The first preset distance D1 can further increase the distance between the injection molding area of ​​the edge-binding structure 12 and the functional layer 200, thereby further reducing the squeezing effect of the edge-binding structure 12 on the functional layer 200 during the injection molding process.

[0051] Optionally, in some embodiments, the first preset spacing D1 can be greater than or equal to 1 mm. For example, the first preset spacing D1 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm or 8 mm, etc.

[0052] Optionally, the edging structure 12 described above in this application may include three forms: single-sided edging, double-sided edging, or semi-enclosed edging.

[0053] Please continue reading. Figures 2 to 4 Correspondingly, all of the edging structures 12 are single-sided edging structures, and all of their structures are arranged on the surface of the first glass layer 100 on the side away from the functional layer 200.

[0054] Please see Figure 4 In one embodiment, the edge-binding structure 12 may include an edge-binding body 121, which is connected to the surface of the first glass layer 100 on the side away from the functional layer 200. This helps to achieve single-sided injection molding of the edge-binding structure 12 at the edge of the glass assembly 11. Compared with double-sided edge-binding, it can reduce the squeezing effect on the functional layer 200 during the injection molding process, thereby reducing the probability of defects such as MURA black spots.

[0055] Please see Figures 2 to 4 In some embodiments, the edging structure 12 may include a guide rail 123, which may be used, but is not limited to, for sliding of the vehicle's glass window. It should be noted that the guide rail 123 may be an accessory to the edging structure 12 for connection to the glass assembly 11.

[0056] Please see Figure 5 and Figure 6 Accordingly, the edging structure 12 is a semi-enclosed edging, with a portion of its structure arranged on the surface of the first glass layer 100 away from the functional layer 200, and the other portion arranged on the boundary 11a of the glass assembly 11.

[0057] In this embodiment, the edge-sealing structure 12 includes an edge-sealing body 121 and an edge-sealing side portion 122. The edge-sealing body 121 is connected to the surface of the first glass layer 100 on the side opposite to the functional layer 200, and the edge-sealing side portion 122 is connected to the boundary 11a of the glass assembly 11 along the width direction of the glass assembly 11. It is worth noting that the edge-sealing structure 12 of this embodiment can also achieve single-sided injection molding at the edge of the glass assembly 11, thereby reducing the probability of defects such as MURA black spots, while the edge-sealing side portion 122 helps to increase the coverage area and improve the protection of the glass assembly 11.

[0058] In other embodiments, depending on actual needs, the edging structure 12 of the glass assembly 10 described above can also be implemented as a double-sided edging (not shown). The double-sided edging completely covers the first glass layer 100, the boundary 11a of the glass assembly 11, and the second glass layer 300 at the edge of the glass assembly 11. It is worth noting that in this embodiment, the portions of the edging structure 12 located on the surfaces of the first glass layer 100 and the second glass layer 300 must meet the requirement that they do not overlap with the functional layer 200 in the orthographic projection direction of the second glass layer 300, or that the width of the overlapping area between the edging structure 12 and the functional layer 200 in the orthographic projection direction of the second glass layer 300 is less than or equal to 1 mm. This can reduce the extrusion pressure on the functional layer 200 during injection molding, thereby reducing the probability of defects such as MURA spots. Users can choose any one or a combination of the above-mentioned single-sided edging, double-sided edging, or semi-enclosed edging forms according to actual needs.

[0059] Please continue reading. Figure 2 In some embodiments, the boundary 200a of the functional layer 200 and the boundary 11a of the glass assembly 11 are provided with a second preset distance D2. This can prevent the functional layer 200 from overflowing at the boundary 11a of the glass assembly 11, and also provide sufficient space for the arrangement of the edge-wrapping structure 12. This ensures that the edge-wrapping structure 12 has sufficient injection volume while avoiding the squeezing effect on the functional layer 200 during the injection molding process.

[0060] Optionally, the aforementioned second preset spacing D2 can be set to be greater than or equal to 3mm, such as 3mm, 4mm, 5mm, 6mm or 8mm, etc. In this way, the boundary 200a of the functional layer 200 can be set in a reasonable position relative to the boundary of the first glass layer 100 and the second glass layer 300 (i.e. the boundary 11a of the glass assembly 11), so as to achieve the aforementioned effect of ensuring that the edge-wrapping structure 12 has sufficient injection volume while avoiding the squeezing effect on the functional layer 200 during the injection molding process.

[0061] Please see Figure 2 In some embodiments, the boundary 200a of the functional layer 200 may be connected to a sealing frame 210, which helps to improve the sealing effect of the functional layer 200.

[0062] Optionally, the sealing portion 210 may be implemented as PVB adhesive, etc.

[0063] Please continue reading. Figure 2 In some embodiments, the edge of the glass assembly 11 is provided with a patching structure 211 and a plurality of support members 211a. The patching structure 211 fills the space between the first glass layer 100 and the second glass layer 300, and the plurality of support members 211a are embedded within the patching structure 211 to improve the overall strength of the glass assembly 11 and the protection of the functional layer 200. Specifically, the plurality of support members 211a are used to mitigate the impact of injection molding pressure on the functional layer, thereby improving the protection of the functional layer 200.

[0064] In some embodiments, the patching structure 211 can fill the gap in the side of the frame portion 210 away from the functional layer 200.

[0065] Optionally, the support may be implemented as a PS (Polystyrene, photoblocking pad or photolithography spacer) support post or other adhesive post, etc.

[0066] Please continue reading. Figure 4 In some embodiments, a first shielding portion 400 may be attached to the surface of the first glass layer 100 facing the functional layer 200, covering the frame portion 210. This helps to prevent the frame portion 210 from being seen from the corresponding side of the glass assembly 11, improving aesthetics. Understandably, the corresponding side refers to the side of the first glass layer 100 facing away from the functional layer 200. For example, the first glass layer 100 may be implemented as the interior glass of a vehicle, thus preventing the user from seeing the aforementioned frame portion 210 from inside the vehicle, improving the user experience.

[0067] Understandably, the aforementioned first shielding portion 400 covering the frame portion 210 means that the boundary 400a of the first shielding portion 400 is aligned with the inner boundary of the frame portion 210 in the width direction of the glass assembly 11, or that the boundary of the first shielding portion 400 extends a small portion beyond the inner boundary of the frame portion 210, thus ensuring that the first shielding portion 400 can completely cover the frame portion 210. It should be noted that the aforementioned inner boundary of the frame portion 210 can be understood in this application as the boundary that is attached to the boundary 200a of the functional layer 200.

[0068] Preferably, the boundary 400a of the first shielding portion 400 extends slightly beyond the inner boundary of the frame portion 210 in the width direction of the glass assembly 11, thus ensuring that the first shielding portion 400 can completely cover the frame portion 210.

[0069] Alternatively, please continue reading Figure 4 Based on the fact that the first shielding part 400 completely covers the frame part 210, a third preset distance D3 can be provided between the boundary 400a of the first shielding part 400 away from the boundary 11a of the glass assembly 11 and the frame part 210. This can ensure that the first shielding part 400 has sufficient coverage area, thereby ensuring the coverage effect on the frame part 210.

[0070] Optionally, the third preset spacing D3 can be set to be greater than or equal to 1 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, or 6 mm. Further, the third preset spacing D3 can be set to be less than or equal to 3 mm, which can further strictly control the extent of the first shielding portion 400 and improve the visibility range of the functional layer 200. For example, the third preset spacing D3 can be 3 mm, 2 mm, or 1 mm.

[0071] Please continue reading. Figure 4 In some embodiments, a second shielding portion 500 may be attached to the surface of the second glass layer 300 facing away from the functional layer 200. The second shielding portion 500 covers the frame portion 210, which helps to prevent the frame portion 210 from being seen from the corresponding side of the glass assembly 11, thus improving aesthetics. Understandably, the corresponding side refers to the side of the second glass layer 300 facing away from the functional layer 200. More specifically, the second glass layer 300 may be implemented as the outer glass of a vehicle, thus preventing the user from seeing the aforementioned frame portion 210 from outside the vehicle, improving the user experience.

[0072] Understandably, the aforementioned second shielding portion 500 covering the frame portion 210 means that the boundary 500a of the second shielding portion 500 is aligned with the inner boundary of the frame portion 210 in the width direction of the glass assembly 11, or that the boundary 500a of the second shielding portion 500 extends a small portion beyond the inner boundary of the frame portion 210, so as to ensure that the second shielding portion 500 can completely cover the frame portion 210.

[0073] Preferably, the boundary of the second shielding portion 500 extends slightly beyond the inner boundary of the frame portion 210 in the width direction of the glass assembly 11, thus ensuring that the second shielding portion 500 completely covers the frame portion 210. Alternatively, please refer to... Figure 4 Based on the fact that the second shielding part 500 completely covers the frame part 210, a fourth preset distance D4 can be provided between the boundary 500a of the second shielding part 500 away from the boundary 11a of the glass assembly 11 and the frame part 210. The fourth preset distance D4 ensures that the second shielding part 500 can extend beyond the frame part 210 by a small part, thus ensuring that the second shielding part 500 has a sufficient coverage area, thereby ensuring the coverage effect of the frame part 210.

[0074] Optionally, the fourth preset spacing D4 can be set to be greater than or equal to 1mm, such as 1mm, 2mm, 3mm, 4mm or 6mm.

[0075] Furthermore, the fourth preset spacing D4 can be set to less than or equal to 3mm, which can further strictly control the overshoot of the second shielding part 500 and improve the visibility range of the functional layer 200. For example, the fourth preset spacing D4 can be 3mm, 2mm, or 1mm, etc.

[0076] Optionally, the aforementioned first shielding portion 400 and second shielding portion 500 may be implemented as black edge printing ink for vehicles, etc.

[0077] Please refer to the previous document. Figure 2 In some embodiments, a first adhesive layer 800 is provided between the first glass layer 100 and the functional layer 200, and a second adhesive layer 900 is provided between the second glass layer 300 and the functional layer 200, so as to ensure the bonding effect of the glass assembly 11.

[0078] Furthermore, in some embodiments, the thickness of the first adhesive layer 800 can be greater than the thickness of the second adhesive layer 900. Specifically, compared to the first adhesive layer 800, since the first adhesive layer 800 is disposed on the side closer to the edge-binding structure 12, the thickness of the first adhesive layer 800 is made greater than the thickness of the second adhesive layer 900, so that the first adhesive layer 800 can buffer the injection molding impact. Correspondingly, the second adhesive layer 900 can be relatively set to have a smaller thickness to take into account the overall thickness design of the glass assembly 11.

[0079] Of course, in other embodiments, the thickness of the first adhesive layer 800 can also be equal to the thickness of the second adhesive layer 900. Users can choose any of the above solutions according to their actual needs. It is worth noting that in this embodiment, it is preferable to configure the thickness of the first adhesive layer 800 to a value that can buffer the effect of injection molding impact, and then consider the thickness design of the second adhesive layer 900, thereby taking into account the overall thickness design of the glass assembly 11.

[0080] Optionally, in some embodiments, the thickness of the first adhesive layer 800 can be set to be greater than or equal to 0.5 mm, such as 0.5 mm, 0.56 mm, 0.6 mm, 0.66 mm, 0.7 mm, 0.76 mm, 0.8 mm, 0.86 mm, 0.9 mm or 1.0 mm, which helps to improve the overall strength of the glass assembly 11 and reduce the impact of injection pressure.

[0081] Optionally, in some embodiments, the thickness of the second adhesive layer 900 can be set to be less than or equal to 0.4 mm. For example, the second adhesive layer 900 can be set to 0.4 mm, 0.38 mm, 0.36 mm, 0.34 mm, 0.32 mm or 0.3 mm, etc., thereby taking into account the overall thickness design of the glass assembly 11.

[0082] Optionally, the aforementioned first adhesive layer 800 and second adhesive layer 900 may be implemented as, but are not limited to, PVB adhesive, etc.

[0083] Please refer to the previous document. Figure 1 Optionally, in some embodiments, the edge of the glass assembly 11 may include a mounting edge 11b, and the edging structure 12 may include a mounting edging 12b, which covers the mounting edge 11b, and a plurality of mounting members 600 are spaced apart on the mounting edging 12b.

[0084] Specifically, the mounting component 600 is adapted to the corresponding position on the vehicle where the glass assembly 11 is mounted, so as to achieve easy assembly of the glass assembly 11 on the vehicle.

[0085] For example, the glass assembly 11 of this application can be configured as a corner window assembly of a vehicle. Adaptively, the mounting member 600 can be assembled with the guide rail of the rear window of a vehicle. Of course, in some other embodiments, the mounting member 600 can also be assembled to other locations on the vehicle.

[0086] Please continue reading. Figure 1 In some embodiments, the mounting edge 12b includes an extension b1 extending beyond the glass assembly 11 along the extending direction of the mounting edge 12b. Among the plurality of mounting members 600, a first mounting member 610 is included. The first mounting member 610 is disposed at a preset position on the extension b1. The preset position is configured such that the first mounting member 610 and the glass assembly 11 have a fifth preset distance D5 in the extending direction of the extension b1.

[0087] Specifically, during assembly, the mounting member 600 exerts pulling and tearing forces on the edge-wrapping structure 12 to varying degrees, which may in turn have the same pulling effect on the functional layer 200 of the glass assembly 11. Therefore, according to the above embodiments of this application, by setting the first mounting member 610 and the glass assembly 11 with a fifth preset distance D5 in the extension direction of the extension portion b1, it is helpful to reduce the pulling effect of the first mounting member 610 on the glass assembly 11 during assembly.

[0088] Optionally, the fifth preset spacing D5 can be set to be greater than or equal to 10mm, such as 10mm, 11mm, 12mm, 13mm or 14mm.

[0089] It is worth noting that the first mounting member 610 is positioned at the bottom of the glass assembly 11 and close to the glass assembly 11, which helps to improve the installation stability of the glass assembly 11. At the same time, the fifth preset distance D5 between the first mounting member 610 and the glass assembly 11 in the extension direction of the extension portion b1 is also designed to reduce the pulling effect of the first mounting member 610 on the glass assembly 11 during the assembly process.

[0090] In some embodiments, the plurality of mounting members 600 may further include a second mounting member 620, which is disposed on the mounting edge 12b at an end away from the aforementioned first mounting member 610. Understandably, the second mounting member 620 may be arranged on top of the glass assembly 11, thereby cooperating with the first mounting member 610 to improve the installation stability of the glass assembly 11.

[0091] Please see Figure 4In some embodiments, the edging structure 12 may have a draft slope 12c in its thickness direction. The draft slope 12c is disposed on the side of the edging structure 12 away from the boundary 11a of the glass assembly 11 along the width direction of the edging structure 12. The draft slope 12c is disposed away from the vertical direction of the first glass layer 100 in the direction away from the functional layer 200. This helps to reduce the contact area between the edging structure 12 and the injection mold when the glass assembly 11 is demolded, thereby improving the ease of demolding. At the same time, it can also reduce the pulling effect of friction on the functional layer 200 during demolding, protect the structure of the functional layer 200, and thus reduce the probability of defects such as MURA black spots.

[0092] Please continue reading. Figure 4 Optionally, the draft angle 12c is set at a preset angle α with the positive perpendicular direction of the first glass layer 100. The preset angle α can be set to be greater than or equal to 8°, which helps to set the angle of the draft angle 12c within a reasonable range, so as to ensure the demolding effect of the glass component 11 while taking into account the injection volume of the edge-wrapping structure 12.

[0093] Optionally, the thickness of the first glass layer 100 can be set to be greater than or equal to 1.8 mm, which can improve the overall strength of the glass assembly 11 and reduce the squeezing effect of the edge-wrapping structure 12 during the injection molding process.

[0094] For example, the thickness of the aforementioned first glass layer 100 can be 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.3mm, 2.5mm or 3.0mm, etc.

[0095] Correspondingly, the thickness of the second glass layer 300 can also be set to be greater than or equal to 1.8 mm.

[0096] For example, the thickness of the aforementioned second glass layer 300 can be 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.3mm, 2.5mm or 3.0mm, etc.

[0097] Please see Figure 6 In some embodiments, the edging structure 12 and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300. The edge of the glass assembly 11 may also be provided with an adhesive region 700a, which is disposed on the surface of the first glass layer 100 on the side facing away from the functional layer 200. Specifically, this adhesive region 700a is used to coat an adhesive such as PU glue, and is used to bond the glass assembly 11 to other components, such as the sheet metal of a vehicle, during assembly, thereby improving the installation stability of the glass assembly 11.

[0098] Please continue reading. Figure 6In some embodiments, the adhesive region 700a and the functional layer 200 do not overlap in the orthographic projection direction Y of the second glass layer 300; or the width of the overlapping area between the adhesive region 700a and the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 can be set to a sixth preset spacing D6, wherein the sixth preset spacing D6 is less than or equal to 3mm, which helps to reduce the squeezing effect of the adhesive region 700a on the functional layer 200 in the orthographic projection direction Y of the second glass layer 300.

[0099] It should be noted that, in this embodiment, the adhesive area 700a and the edge-wrapping structure 12 can be regarded as an integral structure. Thus, the adhesive area 700a can preferably be configured so that it does not overlap with the functional layer 200 in the orthogonal projection direction Y of the second glass layer 300, so as to reduce the squeezing effect of the adhesive 700 on the functional layer 200 in the orthogonal projection direction Y of the second glass layer 300 after the adhesive 700 is provided.

[0100] But please see Figure 5 In most arrangements, to meet the requirements of spatial arrangement, the width of the overlapping area between the aforementioned adhesive area 700a and the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 can be configured as a sixth preset spacing D6, which is less than or equal to 3mm. This satisfies the relatively compact spatial arrangement of the adhesive area 700a, and at the same time, it can set the sixth preset spacing D6 of the overlapping area within a reasonable range to reduce the squeezing effect of the adhesive 700 on the functional layer 200 in the orthographic projection direction Y of the second glass layer 300 after the adhesive 700 is installed.

[0101] For example, the aforementioned sixth preset spacing D6 can be 3mm, 2mm, 1mm, 0.5mm, etc. Preferably, when space arrangement conditions permit, the bonding area 700a is preferably configured so that it does not overlap with the functional layer 200 in the orthogonal projection direction Y of the second glass layer 300, thereby reducing the squeezing effect of the adhesive 700 on the functional layer 200.

[0102] According to another aspect of this application, this application also provides a vehicle that may include the aforementioned glass assembly 10.

[0103] 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.

[0104] 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.
