Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority from a Chinese patent application filed on January 13, 2023, bearing application number 202310065227.3, and the contents disclosed in the above patent application are incorporated herein by reference.

[0002] This application relates to the field of glass technology, in particular to laminated glass and vehicle door glass.

[0003] This application relates to the vehicle field, and more particularly to vehicles. [Background technology]

[0004] Laminated glass is widely used as window glass for vehicles or buildings because it does not scatter fragments when broken and is therefore highly safe. However, since the edge of the laminated glass must be fitted with a sealing member such as a sealing strip, the edge pushes out the sealing member. When the laminated glass slides, for example, in the case of a vehicle door glass that needs to be raised or lowered, not only is there a pushing force but also a frictional force between the edge and the sealing member, which causes the sealing strip to be easily worn, shortening its service life and affecting the stability of the laminated glass itself. Summary of the Invention [Problem to be solved by the invention]

[0005] The present application aims to provide laminated glass, a glass for a vehicle door, to solve the technical problem that the extrusion force between the edge of the existing laminated glass and the sealing member is too large, which causes the sealing strip to wear, shortens its service life, and reduces the stability of the laminated glass itself.

[0006] The above object of the present application can be achieved by adopting the following technical solutions. [Means for solving the problem]

[0007] The present application provides a laminated glass comprising a first glass sheet and a second glass sheet arranged in a stacked manner, with an adhesive layer provided between the first glass sheet and the second glass sheet, and a sealing edge fitted with a sealing member, the sealing edge including a first edge face located at the edge of the first glass sheet and a second edge face located at the edge of the second glass sheet, wherein the first edge face extends outward in the extension direction of the laminated glass relative to the second edge face, forming a deviation of more than 0.5 mm but less than 3 mm, and the second edge face comprises two symmetrically arranged arc-shaped edge faces, with the arc angle of the arc-shaped edge faces not exceeding 90 degrees.

[0008] In the embodiment of the present application, the first end surface is a semicircular end surface, and the two arc-shaped end surfaces of the second end surface have an arc angle of 90 degrees and are connected to form a semicircular end surface.

[0009] In an embodiment of the present application, the vertical distance A between the point where the tangent line between the first end face and the second end face meets the first end face and the point closest to the tangent line on the second end face is 0.4 mm to 2.4 mm, and the vertical distance B between the point where the tangent line meets the extension of the outer surface of the second glass plate meets the tangent line and the tangent line is 0.5 mm to 2.8 mm.

[0010] In the embodiment of the present application, the vertical distance A is in the range of 1.1 mm to 1.47 mm, and the vertical distance B is in the range of 1.29 mm to 1.72 mm.

[0011] In the embodiment of the present application, the vertical distance A is in the range of 1.6 mm to 2 mm, and the vertical distance B is in the range of 1.9 mm to 2.32 mm.

[0012] In the embodiment of the present application, the tangent line and the extension line intersect to form an included angle C, and the radius of the arc-shaped end face is R, then the included angle C=2*arctan(R / (R-(BA))).

[0013] In the embodiment of the present application, the included angle is 110° to 140°.

[0014] In the embodiment of the present application, the included angle is 113.6° to 122.8°.

[0015] In the embodiment of the present application, the included angle is 130.9° to 134.6°.

[0016] In an embodiment of the present application, the second glass plate has a thickness smaller than that of the first glass plate, and the first glass plate is provided facing the side of the laminated glass that receives a larger external load.

[0017] In an embodiment of the present application, the thickness of the first glass sheet is 2.8 mm, and the thickness of the second glass plate is less than 1.4 mm.

[0018] In an embodiment of the present application, the tangent to the first end surface and the second end surface forms a limiting boundary, and the edge of the adhesive layer is positioned so as not to exceed the limiting boundary.

[0019] The present application provides a vehicle window glass made of the above laminated glass.

[0020] The present application provides a vehicle including the laminated glass. [Effects of the Invention]

[0021] The features and advantages of the present application are as follows:

[0022] The laminated glass, vehicle window glass, and vehicle of the present application have a first end surface that extends outward relative to the second end surface, forming a gap of more than 0.5 mm but less than 3 mm, and two arc-shaped end surfaces are symmetrically arranged on the second end surface. This allows the first end surface and the second end surface to cooperate to better support the force between the laminated glass and the sealing member, ensuring that the extrusion force between the laminated glass and the sealing member meets the design requirements and avoids the problem of the sealing member being easily worn out and shortening its service life due to the extrusion force being too large between the laminated glass and the sealing member. This also improves the stability and smooth movement of the laminated glass itself, prevents unnecessary sliding noise, and improves the NVH performance of the vehicle.

[0023] In the following, in order to more clearly explain the technical solutions of the embodiments of the present application, a brief description will be given of the drawings used in the description of the embodiments. However, the drawings described below are only some of the embodiments of the present application, and it goes without saying that other drawings can be obtained based on these drawings without requiring any innovative ingenuity by ordinary skilled persons in the technical field of this invention. [Brief explanation of the drawings]

[0024] [Figure 1] Schematic diagram of the structure of laminated glass according to the present application [Figure 2] Partially enlarged view of laminated glass according to the present application [Figure 3] 1 is a schematic diagram of the included angle in laminated glass according to the present application (adhesive layer omitted). DETAILED DESCRIPTION OF THE INVENTION

[0025] The following provides a clear and complete description of the technical solutions according to the embodiments of the present application based on the drawings according to the embodiments of the present application, but these embodiments are only some of the embodiments of the present application, and not all of the embodiments of the present application. It should be understood that all other embodiments that can be obtained by those skilled in the art of the present invention based on the embodiments of the present application without any innovative ideas fall within the scope of protection of the present application.

[0026] As shown in Figures 1 and 2, the laminated glass of the present application comprises a first glass sheet 1 and a second glass sheet 2 stacked together, with an adhesive layer 3 provided between the first glass sheet 1 and the second glass sheet 2, and a sealing edge to be fitted with a sealing member, the sealing edge including a first edge surface 14 located at an edge surface 11 of the first glass sheet 1 and a second edge surface 24 located at an edge surface 21 of the second glass sheet 2, the first edge surface 14 extending outward (i.e., away from the center) from the second edge surface 24 along an extension direction S of the laminated glass to form a gap E, the gap E being greater than 0.5 mm and less than 3 mm, and the second edge surface 24 having two symmetrically arranged arc-shaped edge surfaces, with the arc angle of the arc-shaped edge surfaces not exceeding 90 degrees.

[0027] Here, the two arcuate end faces respectively consist of an outer arcuate end face 241 connected to the outer surface 22 of the second glass plate 2 and an inner arcuate end face 242 connected to the inner surface 23 of the second glass plate 2.

[0028] In this application, the slippage of the laminated glass is adjusted to more than 0.5 mm but less than 3 mm, and two symmetrical arc-shaped end faces are provided on the second end face 24. This allows the first end face 14 and the second end face 24 to cooperate to better support the force between the laminated glass and the sealing member, ensuring that the extrusion force between the laminated glass and the sealing member meets the design requirements and avoiding the problem of the sealing member being easily worn and shortening its service life due to excessive extrusion force between the laminated glass and the sealing member. This also improves the stability and smooth movement of the laminated glass itself, preventing unnecessary sliding noise, and improving the NVH performance of the vehicle. Meanwhile, because the effect of improving the extrusion force in cooperation with the first end face 14 is primarily embodied by the outer arc-shaped end face 241, the provision of two symmetrical arc-shaped end faces in this application eliminates the need to distinguish between the two sides of the second glass sheet 2 during edge grinding and installation, making processing and installation easier.

[0029] Although it is difficult to directly measure the push-out force between the laminated glass and the sealing material, considering that the laminated glass must be fitted into the sealing material against this push-out force when installed, the smaller the installation force used when installing the laminated glass, the smaller the push-out force between the laminated glass and the sealing material. Therefore, the installation force of the laminated glass can be used as an indicator to evaluate the effect of improving the push-out force. For example, when a vehicle window glass made of laminated glass is inserted between two sealing strips on a vehicle door body along its lifting direction, the front and rear ends of the vehicle window glass are sealed, slid, and fitted into the two sealing strips along the lifting direction.

[0030] To illustrate the effect of adjusting the ejection force by adjusting the offset E in the present application, the following table shows a comparison of the mounting force between one preferred embodiment of the present application and two comparative examples, all of which have the same parameters but different offsets, as well as a comparative example with no offset. In this case, the radii R of the inner arc-shaped end surface 242 and the outer arc-shaped end surface 241 are both 0.55 mm.

[0031] [Table 1]

[0032] As can be seen from this, when the deviation E is greater than 0.5 mm and less than 3 mm, the mounting force is significantly reduced, i.e., the improvement in the push-out force is significant, compared to when the deviation E is equal to 0.5 mm, equal to 3 mm, and when there is no deviation, i.e., when the deviation E is outside the above range.

[0033] In one embodiment of the present application, the outer arc-shaped end surface 241 and the inner arc-shaped end surface 242 are connected to form a semicircular end surface, with their arc angles both being 90 degrees. That is, the radius of the second end surface 24, which is the radius of the outer arc-shaped end surface 241 and the inner arc-shaped end surface 242, is equal to half the thickness t of the second glass sheet 2. Forming the second end surface 24 directly on the semicircular end surface 24 simplifies processing, and the radius of the second end surface 24 can be determined based on the thickness of the second glass sheet 2. In some other embodiments of the present application, the arc angles of the outer arc-shaped end surface 241 and the inner arc-shaped end surface 242 may both be less than 90 degrees. In some other embodiments of the present application, the outer arc-shaped end surface 241 and the inner arc-shaped end surface 242 are connected via a linearly extending flat end surface.

[0034] Similarly, in one embodiment of the present application, the first end surface 14 may be a semicircular end surface, and the radius of the first end surface 14 may be equal to half the thickness T of the first glass sheet 1. In one or more embodiments, the radius of the first end surface 14 may be greater than or less than half the thickness T of the first glass sheet 1, i.e., the size of the first glass sheet 1 is the same as the size of the glass sheets in the laminated glass according to the related art, and no adjustment is required. In another possible embodiment of the present application, the first end surface 14 may also be a chamfered polygonal end surface with rounded corners, such as an isosceles trapezoid.

[0035] The present application has found that the extrusion force between the laminated glass and the sealing member can be improved by further adjusting deviation E to form the laminated glass in the following state: As shown in Figure 3, in this state, the vertical distance A between the point of contact M of the tangent line F between the first end surface 14 and the second end surface 24 and the first end surface 14 and the point N closest to the tangent line F on the second end surface 24 may be 0.4mm to 2.4mm, and the intersection point of the tangent line F with the extension line S of the outer surface 22 of the second glass sheet 2 and the point N closest to the tangent line F may be 0.4mm to 2.4mm. M The vertical distance B between them may be 0.5 mm to 2.8 mm.

[0036] The vertical distance A according to the present application may specifically be in a standard range of 1.1 mm to 1.47 mm, and the vertical distance B may specifically be in a standard range of 1.29 mm to 1.72 mm.

[0037] The vertical distance A according to the present application can be specifically in another standard range of 1.6 mm to 2 mm, and the vertical distance B can be specifically in another standard range of 1.9 mm to 2.32 mm.

[0038] Furthermore, by adjusting the offset E and the radius R of the second edge 24, or by determining the radius R of the second edge 24 and then adjusting the offset E, the extrusion force between the laminated glass and the sealing member can be improved when the laminated glass is formed as follows: As shown in FIG. 3 , the tangent F intersects with the extension line K of the second glass sheet 2 (i.e., the extension direction S of the laminated glass) to form an included angle C. If the angle of the included angle C is defined as the included angle C, the relationship of the included angle C=2*arctan(R / (R-(B-A))) can be satisfied. Because the vertical distance A is related to the vertical distance B and the offset E, the included angle C can be changed by adjusting the offset E and the radius R. In other words, the present application proposes to derive the included angle C based on the relationship between the extrusion force, the offset E, and the radius R. Controlling the included angle C improves the extrusion force, enabling it to meet the requirements.

[0039] The included angle C according to the present application can be in the range of 110° to 140°. When a value within this range is selected as the angle value of the included angle C, the extrusion force after adjustment will have a more significant improvement effect than when a value outside this range is selected.

[0040] The included angle C in the present application can be specifically in the reference range of 113.6° to 122.8°.

[0041] The included angle C according to the present application may be in another reference range, specifically 130.9° to 134.6°.

[0042] The following table shows a comparison of the structural parameters and mounting strength of the laminated glass of the six preferred embodiments of the present application, the two comparative examples, and the comparative example laminated glass with no misalignment, when the radius R is all 0.55 mm, i.e., the thickness t of the second glass plate 2 is 1.1 mm and the thickness of the first glass plate 1 is also the same.

[0043] [Table 2]

[0044] As can be seen from the above table, the mounting strength of the laminated glass of the six preferred embodiments of the present application is significantly reduced compared to the laminated glass of the comparative example where no misalignment occurs, and the mounting strength of the laminated glass of the two comparative examples is reduced to a lesser extent compared to the laminated glass of the comparative example where no misalignment occurs. This explains why the improvement in the push-out force is small when the included angle C is less than 110° or more than 140°.

[0045] As shown in Figures 1 and 2, in order to further reduce the weight and manufacturing costs of the laminated glass, in this embodiment, the thickness t of the second glass sheet 2 is made smaller than the thickness T of the first glass sheet 1. In this embodiment, by adjusting the offset E and the radius R of the second edge surface, a better force is borne between the laminated glass and the sealing member, thereby improving the stability and strength of the laminated glass. Therefore, even after reducing the thickness t of the second glass sheet 2, the stability and strength of the laminated glass can still meet the requirements. In one embodiment, the thickness T of the first glass sheet 1 is greater than 3.2 mm, preferably 3.5 mm or 3.8 mm, and the thickness t of the second glass sheet 2 is less than 1.4 mm, preferably 1.1 mm.

[0046] In one or more embodiments, the thickness T of the first glass plate 1 is 1.6 mm to 5.0 mm, or in the range of 1.4 mm to about 3.85 mm, or in the range of about 1.4 mm to about 3.5 mm, or in the range of about 1.4 mm to about 3.0 mm, or in the range of about 1.4 mm to about 2.8 mm, or in the range of about 1.4 mm to about 2.5 mm, or in the range of about 1.4 mm to about 2.0 mm, or in the range of about 1.5 mm to about 3.85 mm, or in the range of about 1.5 mm to about 3.5 mm, or in the range of about 1.5 mm to about 3.0 mm, or in the range of about 1.5 mm to about 3.85 mm. The thickness may be in the range of 0.5 mm to about 2.8 mm, or in the range of about 1.5 mm to about 2.5 mm, or in the range of about 1.5 mm to about 2.0 mm, or in the range of about 1.6 mm to about 3.85 mm, or in the range of about 1.6 mm to about 3.5 mm, or in the range of about 1.6 mm to about 3.0 mm, or in the range of about 1.6 mm to about 2.8 mm, or in the range of about 1.6 mm to about 2.5 mm, or in the range of about 1.6 mm to about 2.0 mm, or in the range of about 1.8 mm to about 3.5 mm, or in the range of about 2.0 mm to about 3.0 mm.

[0047] In one or more embodiments, the thickness t of the second glass plate 2 may be 0.5 mm to 1.4 mm, or alternatively, the thickness t of the second glass plate 2 may be in the range of about 0.2 mm to about 1.4 mm, or in the range of about 0.3 mm to about 1.4 mm, or in the range of about 0.4 mm to about 1.4 mm, or in the range of about 0.5 mm to about 1.4 mm, or in the range of about 0.1 mm to about 1.1 mm, or in the range of about 0.2 mm to about 1.1 mm, or in the range of about 0.1 mm to about 0.7 mm, or in the range of about 0.2 mm to about 0.7 mm. or in the range of about 0.3 mm to about 0.7 mm, or in the range of about 0.4 mm to about 0.7 mm, or in the range of about 0.2 mm to about 0.6 mm, or in the range of about 0.3 mm to about 0.6 mm, or in the range of about 0.4 mm to about 0.6 mm, or in the range of about 0.2 mm to about 0.5 mm, or in the range of about 0.3 mm to about 0.5 mm, or in the range of about 0.2 mm to about 0.4 mm.

[0048] The stretching direction S of the laminated glass described in this application refers to the planar stretching direction of the laminated glass facing the sealing member. The sealing member to which the laminated glass is fitted may be formed as one or more, and therefore the edge 11 and edge 21 to be fitted to the sealing member provided corresponding to the first glass sheet 1 and the second glass sheet 2 may each be formed as one or more. For example, when the front and rear edges of a vehicle window glass made of laminated glass are sealed and slidably fitted to a sealing strip, the front edge of the first glass sheet 1 extends forward a certain distance relative to the second glass sheet 2, and the rear edge of the first glass sheet 1 extends backward a certain distance relative to the second glass sheet 2, resulting in a misalignment between the front and rear ends of the first glass sheet 1 and the second glass sheet 2.

[0049] To maintain stability when using laminated glass, in an embodiment of the present application, the thicker first glass sheet 1 may be provided on the side of the laminated glass that receives a greater external load. For example, in a side window glass manufactured using laminated glass, the first glass sheet 1 is provided facing the outside of the vehicle and the second glass sheet 2 is provided facing the interior of the vehicle. This allows the thicker and stronger first glass sheet 1 to withstand a strong external load from outside the vehicle, and the relatively stable environment inside the vehicle cabin reduces the impact of the external load on the second glass sheet 2.

[0050] The opposing sides of the first glass plate 1 and the second glass plate 2 are the inner surface 13 of the first glass plate 1 and the inner surface 23 of the second glass plate 2, respectively, and the opposite sides are the outer surface 12 of the first glass plate 1 and the outer surface 22 of the second glass plate 2, respectively. The inner surface 13 of the first glass plate 1 and the inner surface 23 of the second glass plate 2 are bonded together by an adhesive layer 3. The material of the adhesive layer 3 may include, but is not limited to, polyvinyl butyral (PVB), polycarbonate (PC), sound-insulating PVB, light-blocking band PVB, heat-control PVB, ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), polyacetal resin (POM), polybutylene terephthalate (PBT), polyethylene vinyl acetate ( PEVA ), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyacrylate (PA), polymethyl methacrylate (PMMA), and polyurethane foam (PUR) may be used. The thickness of the adhesive layer 3 may be 0.38 mm to 0.76 mm, and preferably 0.76 mm.

[0051] The position and shape of the edge 31 of the adhesive layer 3 facing the sealing member are not specifically limited, but both sides of the adhesive layer 3 are configured to cover as much of the inner surface 13 of the first glass sheet 1 and the inner surface 23 of the second glass sheet 2 as possible so that the adhesive layer 3 can firmly bond the first glass sheet 1 and the second glass sheet 2. Meanwhile, in this embodiment of the present application, the edge 31 of the adhesive layer 3 is provided with an edge 32 (adhering edge surface), and the edge 11 of the first glass sheet 1 and the edge 21 of the second glass sheet 2 are connected to the edge 32 so that the force between the laminated glass and the sealing member can be more effectively received. Specifically, one end of the edge 32 extends to the first edge surface 14, and the other end of the edge 32 extends to the connecting portion between the edge 21 of the second glass sheet 2 and its inner surface 23.

[0052] 2, a tangent line F is formed between the first end surface 14 and the second end surface 25, and in one or more embodiments, the tangent line F forms a limiting boundary, and the edge 32 of the end 31 of the adhesive layer 3 is positioned so as not to exceed the limiting boundary. This arrangement prevents contact between the sealing member and the adhesive layer 3, thereby avoiding disadvantages such as wear, increased resistance, and noise generation that may result from contact between the two.

[0053] In one or more embodiments, the edge 32 of the adhesive layer 3 may be in the form of an oblique line or a recessed shape toward the center of the adhesive layer 3, and it should be understood that all of these fall within the scope of protection of the present application as long as the edge 32 of the adhesive layer 3 is positioned so as not to exceed the above-mentioned limit boundary. Specifically, the edge 32 of the adhesive layer 3 is formed in an oblique shape, which is advantageous for meeting the automated polishing requirements of industrial production and can achieve a better aesthetic effect than other embodiments of the present application.

[0054] The first glass sheet 1 and the second glass sheet 2 may be formed from a variety of materials. According to one or more embodiments, the first glass sheet 1 and the second glass sheet 2 may be formed from the same or different materials. In exemplary embodiments, one or both of the first glass sheet 1 and the second glass sheet 2 may be glass (e.g., soda-lime glass, alkali aluminosilicate glass, alkali-containing borosilicate glass, and / or alkali aluminoborosilicate glass) or glass-ceramic. Examples of suitable glass-ceramics include glass-ceramics in the LiO-AlO-SiO system (i.e., LAS system), glass-ceramics in the MgO-AlO-SiO system (i.e., MAS system), and glass-ceramics containing crystalline phases, where the crystalline phase is mullite, spinel, or arsenic. α -quartz, βThe laminated glass may have one or more crystalline phases selected from the group consisting of quartz solid solution, petalite, lithium disilicate, podumene, nepheline, and alumina. Meanwhile, one or both of the first glass sheet 1 and the second glass sheet 2 may be chemically tempered, thermally tempered, mechanically tempered, or a combination thereof. In one or more embodiments, the first glass sheet 1 is not tempered (meaning that it is not tempered by a chemical, thermal, or mechanical tempering process, but has an annealed substrate), and the second glass sheet 2 is tempered. In one or more embodiments, the first glass sheet 1 may be thermally tempered, and the second glass sheet 2 may be chemically tempered. Specifically, a combination of various tempering methods may be used to ensure that the laminated glass meets the strength requirements for installation in various vehicles, such as frameless glass door assemblies.

[0055] In one embodiment, the surface compressed stress (CS) of the chemically strengthened glass or glass-ceramic substrate can be 300 MPa or greater, e.g., 400 MPa or greater, 450 MPa or greater, 500 MPa or greater, 550 MPa or greater, 600 MPa or greater, 650 MPa or greater, 700 MPa or greater, 750 MPa or greater, or 800 MPa or greater. In one or more embodiments, the surface compressed stress (CS) of the strengthened glass or glass-ceramic substrate is the maximum compressed stress (CS).

[0056] The chemically strengthened glass or glass-ceramic substrate may have a depth of layers (DOL) of about 15 μm or more, 20 μm or more (e.g., 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm or more). In one or more embodiments, the strengthened glass or glass-ceramic substrate may have a maximum center tension (CT) value of 10 MPa or more, 20 MPa or more, 30 MPa or more, or 40 MPa or more (e.g., 42 MPa, 45 MPa, or 50 MPa or more), but should be less than 100 MPa (e.g., 95 MPa, 90 MPa, 85 MPa, 80 MPa, 75 MPa, 70 MPa, 65 MPa, 60 MPa, 55 MPa or less).

[0057] Chemical strengthening of thin glass allows the glass sheets to maintain high strength while remaining sufficiently thin, which is advantageous for reducing the overall weight of the laminated glass without destroying its functionality, allowing users to use vehicles more economically, or increasing the driving range of electric vehicles.

[0058] In one embodiment, the present application provides a vehicle window glass made of laminated glass. The laminated glass according to this embodiment has the same specific structure, operating principle, and beneficial effects as the laminated glass according to the first embodiment, so redundant description will be omitted here.

[0059] In one embodiment, the present application provides a vehicle including the above laminated glass. The laminated glass according to this embodiment has the same specific structure, operating principle, and beneficial effects as the laminated glass according to the first embodiment, so redundant description will be omitted here.
