Description

Technical Field

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

[0002] During the assembly of vehicle window glass with sheet metal, the glass needs to be edge-cut according to the characteristics of the sheet metal outer panel. However, if the initial flanging curvature of the sheet metal is uneven, and the glass contour design is poor, the gap between the glass and the sheet metal after chamfering will be uneven, making it difficult to guarantee the DTS (Discrete Traceability) value. Uneven gaps between the glass and sheet metal can easily affect assembly and manufacturing quality, as they cannot accommodate minute displacements or deformations, easily generating structural stress and thus affecting product lifespan. Uneven gaps also make later repairs more difficult. Summary of the Invention

[0003] In view of this, this application provides a glass profile design method and a vehicle. The uniform gap between the glass and the sheet metal can ensure assembly and manufacturing quality, simplify the production and assembly process, improve production efficiency and consistency, accommodate small displacements or deformations, reduce structural stress, extend product service life, and reduce maintenance difficulty and risk. The glass profile design method ensures the uniformity of the gap between the glass edge and the sheet metal by finding the curve position of the center O1 of the second chamfer and then deducing the position of the glass's tangent edge and cut surface. The vehicle using this window assembly can achieve good sealing performance, effectively preventing the intrusion of moisture, dust and noise, and helps to improve sound insulation and noise reduction performance, reduce abnormal noises during driving, and provide a more comfortable and quiet in-vehicle environment for passengers.

[0004] To achieve the above objectives, this application provides the following technical solution: This application provides a glass profile design method for a vehicle window assembly, the vehicle window assembly including glass and a window, the window having an opening, the opening being sheet metal in the circumferential direction; The glass covers the opening, and the glass includes a first surface and a second surface disposed opposite to each other. The sheet metal has a third surface facing outward from the window. The cut surface of the glass edge is perpendicular to the first surface and the second surface. The intersection of the cut surface and the first surface is a first tangent, and the intersection of the cut surface and the second surface is a second tangent. A second chamfer is provided at the second tangent, and the radii and angles of the first chamfer and the second chamfer are equal. The steps of the glass profile design method include: S1: Determine the position of the curve containing the center O1 of the second chamfer; S2: Determine the position of the first cutting edge based on the position of the curve where the center O1 of the second chamfer is located; S3: Cut the glass along the first cutting edge to obtain a glass outline of a preset shape.

[0005] The glass contour design method of this application, by finding the curve position of the center O1 of the second chamfer, and then deducing the position of the glass's cut edge and cutting surface, ensures the uniformity of the gap between the glass edge and the sheet metal. This method can be applied not only to the rear window assembly, but also to other scenarios involving glass sheet metal fittings without decorative strips, such as side windows and sunroofs.

[0006] The window assembly of this application has a uniform gap between the glass and the sheet metal, which can ensure the quality of assembly and manufacturing, simplify the production and assembly process, improve production efficiency and consistency, accommodate small displacements or deformations, reduce structural stress, extend product service life, and reduce maintenance difficulty and risk.

[0007] Microcracks at the edges of glass can easily propagate and cause the entire pane to shatter when subjected to vibration or stress. Adding a first chamfer and a second chamfer at the first and second cut edges can remove these microcracks, eliminate stress concentration points, and make the glass more durable. This is especially important for vehicle windows, which are frequently exposed to vibration. Furthermore, the smooth, flat chamfered edges allow for a smoother fit to the window's sheet metal and help the sealant and weatherstripping adhere more evenly, improving the window's sealing performance and reducing the risk of rattling and leaks.

[0008] Optionally, no decorative strip and / or bright strip is provided between the glass and the sheet metal.

[0009] The absence of decorative strips and / or bright strips between glass and sheet metal can create a specific appearance style and simplify manufacturing and assembly, reduce the number of parts, streamline the production assembly process, help improve production efficiency, and reduce the risk of matching problems (such as uneven gaps) caused by the assembly of multiple parts and the accumulation of tolerances.

[0010] Optionally, step S1 includes: S11: Determine the locations of the first surface and the third surface; S12: Determine the position of the first offset surface based on the position of the first surface; S13: Determine the position of the second offset surface based on the position of the third surface; S14: The first offset surface and the second offset surface intersect to form a first curve, which is the curve where the center O1 of the second chamfer is located.

[0011] The glass contour design method of this application involves finding the curve position of the center O1 of the second chamfer and then deducing the position of the cut edge and the cut surface 13 of the glass 1. By ensuring that the distance between the center O1 of the second chamfer and the third surface is equal everywhere, the minimum gap between the glass and the sheet metal at all points along the glass edge—that is, the minimum distance between the second chamfer and the third surface—is also equal everywhere, thus ensuring the uniformity of the gap between the glass edge and the sheet metal. Therefore, by finding the curve position of the center O1 of the second chamfer and then using relevant calculation methods to deduce the position of the cut edge and the cut surface of the glass, the cut edge of the glass contour can be quickly determined, and the uniformity of the gap between the glass edge and the sheet metal can be ensured. This improves the production efficiency and assembly accuracy of automotive window glass.

[0012] Optionally, there is a minimum gap between the glass and the sheet metal, and the minimum gap between the glass and the sheet metal is located between the second chamfer and the third surface; step S12 includes: offsetting the first surface in a direction perpendicular to the first surface and close to the third surface to obtain a first offset surface, the offset distance f=t-r2, where: t is the thickness of the glass, and r2 is the radius of the second chamfer; Step S13 includes: offsetting the third surface toward a direction perpendicular to the third surface and close to the first surface to obtain a second offset surface, with an offset distance h = DTS + r2, where DTS is the minimum gap design value between the glass and the sheet metal, and r2 is the radius of the second chamfer.

[0013] This method can quickly deduce the location of the first curve from simple known conditions such as the location of the first surface, the location of the third surface, the thickness t of the glass, the radius r2 of the second chamfer, and the minimum clearance design value DTS between the glass and the sheet metal.

[0014] Optionally, step S2 includes: S21: Project the first curve vertically onto the first surface, and the vertical projection line of the first curve onto the first surface is the first offset curve. S22: The first offset curve is offset along the first surface and close to the third surface by an offset distance of r2 to determine the position of the first cutting edge and the position of the cutting surface.

[0015] The positions of the cutting surface, the first cutting edge, and the second cutting edge can be quickly calculated using the first curve.

[0016] Optionally, the angle of the second chamfer is a right angle or an obtuse angle.

[0017] If the glass needs to withstand significant pressure or vibration, a 90-degree chamfer is usually sufficient for safety requirements in general situations where the primary purpose is to eliminate the risk of cutting hands; choosing an obtuse chamfer can usually distribute stress more effectively and may provide better impact resistance.

[0018] Optionally, the first cut edge is provided with a first chamfer, the angle of the first chamfer is equal to the angle of the second chamfer, or the angle of the first chamfer is greater than the angle of the second chamfer.

[0019] The angle of the first chamfer can be the same as or different from the angle of the second chamfer. Usually, the angle of the first chamfer can be set to the same right angle as the second chamfer, or an obtuse chamfer can be chosen. This can more effectively disperse stress and may result in better impact resistance.

[0020] In a preferred embodiment, the radius r1 of the first chamfer is equal to the radius r2 of the second chamfer.

[0021] To facilitate glass cutting and manufacturing, the radius r1 of the first chamfer is set to be equal to the radius r2 of the second chamfer. Of course, the radius r1 of the first chamfer can also be set to be greater than or less than the radius r2 of the second chamfer, depending on actual needs. During assembly, the rounded edges provide better guidance. For automotive window glass, a larger radius r2 of the second chamfer 32, with its rounded edge transition, also helps the sealant or adhesive to fill and adhere more evenly, thereby improving the sealing effect.

[0022] Optionally, the glass profile design method further includes step S4: setting the first chamfer at the first cut edge according to the radius value r1 and angle of the first chamfer; setting the second chamfer at the second cut edge according to the radius value r2 and angle of the second chamfer.

[0023] By determining the positions of the first and second cut edges, the positions of the first and second chamfers can be calculated, thus completing the cutting and processing of the glass edge.

[0024] Optionally, the glass profile design method further includes step S5: measuring the actual minimum gap value c between the second chamfer and the third surface, and determining whether the actual minimum gap value c meets the requirements of the minimum gap design value DTS.

[0025] The accuracy and effectiveness of this design method for identifying the first and second cut edges of the glass can be verified by measuring the actual gap between the glass and the sheet metal, specifically the gap between the second chamfer and the third surface, and comparing this actual gap value with the design value DTS to check its uniformity.

[0026] Optionally, step S5 includes: S51: Take points along the edge of the glass at specified intervals and measure the actual minimum gap value c between the second chamfer and the third surface at each point; S52: Compare and analyze the actual minimum gap value c at each point, and compare the actual minimum gap value c at each point with the minimum gap design value DTS.

[0027] To verify the glass profile design method, the minimum gap value c between the glass edge and the sheet metal is measured. Specifically, the actual minimum gap value c can be measured at certain intervals (e.g., 1cm) along the edge of the glass, and the measured values ​​are recorded. The variance is observed to see if it is controlled within the allowable range. These values ​​are then compared with the design value DTS. If the error remains within the allowable range, the correctness of the glass profile design method can be verified.

[0028] This application also provides a glass cutting method, which includes: drawing a corresponding glass contour on the first surface of the glass according to the glass contour design method, and cutting along the contour in a direction perpendicular to the first surface.

[0029] First, the corresponding glass outline is drawn on the first surface using a pen or other means to mark the subsequent cutting work and avoid deviations during the cutting process. Then, the glass is cut along the outline using a laser or other methods to quickly and accurately obtain the glass with the preset outline.

[0030] This application also provides a method for assembling a vehicle window assembly, the method comprising: covering the opening of the vehicle window with the glass, and filling the space between the glass and the sheet metal along the circumference of the glass.

[0031] During the assembly of the car window components, after the glass is placed on the sheet metal, a feeler gauge can be used to check the actual minimum gap value c between the glass and the sheet metal. Specifically, the actual minimum gap value c can be measured at certain intervals (such as 1cm) along the edge of the glass, and the measured values ​​can be recorded. The variance can be observed to see if it is controlled within the allowable range. These values ​​can then be compared with the design value DTS. If the error is kept within the allowable range, the correctness of the glass contour cutting can be verified.

[0032] The method for assembling the vehicle window assembly in this application ensures that the actual minimum gap between the glass and the sheet metal is equal everywhere. When filling the gap between the glass and the sheet metal with sealant, it is only necessary to move the glue gun at a uniform speed along the edge of the glass. There is no need to prolong the dwell time in areas with large gaps or reduce the dwell time in areas with small gaps, which would result in poor sealing or affect the appearance due to excessive or insufficient glue application.

[0033] This application also provides a vehicle including the aforementioned window assembly.

[0034] The vehicle of this application uses the window assembly of this application. The uniform gap between the glass and the sheet metal provides a stable and consistent filling space for the sealant or sealing strip, ensuring good sealing performance, effectively preventing moisture, dust and noise from entering, avoiding direct contact between the glass and the sheet metal or local stress concentration, and preventing the glass from being squeezed, twisted or even broken due to vibration, thermal expansion and contraction or body torsion. Good sealing performance also helps to improve sound insulation and noise reduction performance, reduce abnormal noises during driving, and provide a more comfortable and quiet in-vehicle environment for passengers.

[0042] This application provides a glass contour design method, a cutting method, a window assembly method, and a vehicle. The uniform gap between the glass and the sheet metal ensures assembly and manufacturing quality, simplifies the production and assembly process, improves production efficiency and consistency, accommodates minor displacements or deformations, reduces structural stress, extends product lifespan, and reduces maintenance difficulty and risk. This design method ensures uniformity of the gap between the glass edge and the sheet metal by finding the curve position of the center of the second chamfer and then deducing the position of the glass's cut edge and cut surface. When this window assembly is used in a vehicle, it can achieve good sealing performance, effectively preventing moisture, dust, and noise intrusion, and also helps to improve sound insulation and noise reduction performance, reduce abnormal noises during driving, and provide a more comfortable and quiet in-vehicle environment for occupants.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] like Figures 1-5 As shown, this application provides a glass profile design method for a vehicle window assembly, the vehicle window assembly including glass 1 and a vehicle window, the vehicle window having an opening, the circumferential direction of the opening being sheet metal 2; Glass 1 covers the opening. Glass 1 includes a first surface 11a and a second surface 12a arranged opposite to each other. The first surface 11a faces outward from the window, and the second surface 12a faces inward from the window. Sheet metal 2 has a third surface 21a facing outward from the window. The cut surface 13 of the edge of glass 1 is perpendicular to the first surface 11a and the second surface 12a. The intersection of the cut surface 13 and the first surface 11a is the first cut edge 33c, and the intersection of the cut surface 13 and the second surface 12a is the second cut edge. A second chamfer 32 is provided at the second cut edge. The second chamfer 32 is also a 90-degree chamfer, or it can be an obtuse angle. To facilitate the determination of the center position of the chamfer and the subsequent calculation process, the radii of the first chamfer 31 and the second chamfer 32 are equal and the angles are equal (in the following embodiments, right angles are assumed to be used). The steps of this glass contour design method include: S1: Determine the curve where the center O1 of the second chamfer 32 is located, which is also the position of the first curve 33a; S2: Determine the position of the first tangent 33c based on the curve where the center O1 of the second chamfer 32 is located, that is, the position of the first curve 33a; S3: Cut glass 1 along the first cutting edge 33c to obtain a glass outline of a preset shape.

[0045] In the glass profile design method of this application, firstly, in step S1, the position of the first curve 33a is found, such as... Figures 2-5 As shown in the figure, it is a cross-sectional view of a certain cross section of glass 1 and sheet metal 2. The cross section passes through the normal line of a certain point on the first cut edge 33c of glass 1 and is perpendicular to the cutting surface 13. The center O1 of the second chamfer 32 of the second cut edge forms a closed curve along the edge of glass 1, which is the first curve 33a. The intersection of the first curve 33a and the cross section in the figure is the position of point O1 in the figure. Then, in step S2, the position of the first cutting edge 33c is calculated based on the position of the first curve 33a. For example, the first curve 33a is vertically projected onto the first surface 11a to obtain the corresponding vertical projection line. Then, the vertical projection line is moved along the first surface 11a toward the third surface 21a by the radius of the second chamfer 32, which allows the position of the first cutting edge 33c to be calculated, thereby obtaining the position of the cutting surface 13, and thus the position of the second cutting edge. Then, in step S3, the glass 1 is cut along the first cutting edge 33c. Based on the positions of the first cutting edge 33c and the second cutting edge, the first chamfer 31 and the second chamfer 32 are processed and set to complete the processing of the entire edge of the glass 1, thereby obtaining the glass outline of the preset shape.

[0046] The glass contour design method of this application involves finding the curve position of the center O1 of the second chamfer 32 and then deducing the position of the cut edge and the cut surface 13 of the glass 1. By ensuring that the distance between the center O1 of the second chamfer 32 and the third surface 21a is equal everywhere, the minimum gap between the glass 1 and the sheet metal 2 at all points along the edge of the glass 1, i.e., the minimum distance between the second chamfer 32 and the third surface 21a, is also equal everywhere, thus ensuring the uniformity of the gap between the edge of the glass 1 and the sheet metal 2. Therefore, by finding the curve position of the center O1 of the second chamfer 32 and then deducing the position of the cut edge and the cut surface 13 of the glass 1 using relevant calculation methods, the cut edge of the glass contour can be quickly determined, and the uniformity of the gap between the edge of the glass 1 and the sheet metal 2 can be ensured, thereby improving the production efficiency and assembly accuracy of automotive window glass.

[0047] In addition, this method can be applied not only to the window components of the front and rear windows, but also to other scenarios where glass sheet metal is used without decorative strips, such as side windows and sunroofs.

[0048] In a preferred embodiment, such as Figures 3-5 As shown, step S1 includes: S11: Determine the positions of the first surface 11a and the third surface 21a; S12: Determine the position of the first offset surface 11b based on the position of the first surface 11a; S13: Determine the position of the second offset surface 21b based on the position of the third surface 21a; S14: The first offset surface 11b and the second offset surface 21b intersect to obtain the first curve 33a, which is the curve where the center O1 of the second chamfer 32 is located.

[0049] This method can first calculate the positions of the relevant auxiliary surfaces, namely the first offset surface 11b and the second offset surface 21b, from the positions of the first surface 11a and the third surface 21a, and then quickly calculate the position of the first curve 33a.

[0050] In a preferred embodiment, there is a minimum gap between the glass 1 and the sheet metal 2, which is located between the second chamfer 32 and the third surface 21a; step S12 includes: offsetting the first surface 11a in a direction perpendicular to the first surface 11a and close to the third surface 21a to obtain a first offset surface 11b, with an offset distance f=t-r2, where: t is the thickness of the glass 1 and r2 is the radius of the second chamfer 32; Step S13 includes: offsetting the third surface 21a in a direction perpendicular to the third surface 21a and close to the first surface 11a to obtain a second offset surface 21b, with an offset distance h = DTS + r2, where DTS is the minimum gap design value between the glass 1 and the sheet metal 2, and r2 is the radius of the second chamfer 32.

[0051] This example illustrates the specific process of determining the curve containing the center O1 of the second chamfer 32. First, to find the curve containing the center O1 of the second chamfer 32, i.e., the position of the first curve 33a, we can obtain the position of the first curve 33a by intersecting two surfaces. Here, we take two surfaces related to the first surface 11a and the third surface 21a: the first offset surface 11b and the second offset surface 21b. The first offset surface 11b is obtained by translating the first surface 11a, and the second offset surface 21b is obtained by translating the third surface 21a. The intersection line of the first offset surface 11b and the second offset surface 21b is the first curve 33a. Specifically, assuming the position of the first curve 33a is known, if the first offset surface 11b is to pass through the position of the first curve 33a, its distance from the first surface 11a is the thickness t of the glass minus the radius r2 of the second chamfer 32. Assuming the position of the first curve 33a is known, if the second offset surface 21b is to pass through the position of the first curve 33a, its distance from the third surface 21a is the DTS value plus the radius r2 of the second chamfer 32; We can see from Figure 4 As can be seen from the figure, the distance f between the first surface 11a and the first offset surface 11b is the thickness t of the glass 1 minus the radius r2 of the second chamfer 32; Similarly, the distance h between the third surface 21a and the second offset surface 21b is the DTS value plus the radius r2 of the second chamfer 32; Therefore, we can deduce the method for determining the position of point O1 from the above process. This method can quickly calculate the position of the first curve 33a from simple known conditions such as the position of the first surface 11a, the position of the third surface 21a, the thickness t of the glass 1, the radius r2 of the second chamfer 32, and the minimum clearance design value DTS between the glass 1 and the sheet metal 2.

[0052] In a preferred embodiment, such as Figures 3-5 As shown, step S2 includes: S21: Project the first curve 33a vertically onto the first surface 11a. The vertical projection line of the first curve 33a onto the first surface 11a is the first offset curve 33b. Specifically, the distance by which the first curve 33a is offset in a direction perpendicular to and close to the first surface 11a is f. S22: The first offset curve 33b is offset along the first surface 11a and close to the third surface 21a by an offset distance of r2 to determine the position of the first cutting edge 33c and the position of the cutting surface 13. This embodiment is a process of calculating the positions of the cutting surface 13, the first cutting edge 33c and the second cutting edge through the first curve 33a. First, in step S21, the curve where the center O1 of the second chamfer 32 is located, that is, the first curve 33a, is offset by f in a direction perpendicular to and close to the first surface 11a, so as to reach the first surface 11a and achieve the intersection with the first surface 11a. The intersection line is the first offset curve 33b. Then, in step S22, the first offset curve 33b is offset along the first surface 11a and close to the third surface 21a by an offset distance equal to the radius r2 of the second chamfer 32, thus obtaining the position of the first cutting edge 33c. Then, by making a perpendicular plane to the first surface 11a at the first cutting edge 33c, the cutting surface 13 is obtained. The cutting surface 13 intersects with the second surface 12a, thus obtaining the position of the second cutting edge.

[0053] In a preferred embodiment, the angle of the second chamfer 32 is a right angle or an obtuse angle.

[0054] If the glass needs to withstand significant pressure or vibration, a right-angle chamfer is usually sufficient for safety requirements in general situations where the primary purpose is to eliminate the risk of cutting hands; choosing an obtuse chamfer can more effectively disperse stress and may provide better impact resistance.

[0055] In a preferred embodiment, a first chamfer 31 is provided at the first cut edge 33c. The first chamfer 31 is usually a 90-degree chamfer, but it can also be an obtuse angle. The angle of the first chamfer 31 is equal to the angle of the second chamfer 32, or the angle of the first chamfer 31 is greater than the angle of the second chamfer 32.

[0056] The angle of the first chamfer 31 can be the same as or different from the angle of the second chamfer 32. Usually, the angle of the first chamfer 31 can be set to the same right angle as the second chamfer 32, or an obtuse chamfer can be selected to achieve better stress dispersion and impact resistance.

[0057] In a preferred embodiment, the radius r1 of the first chamfer 31 is equal to the radius r2 of the second chamfer 32.

[0058] To facilitate glass cutting and manufacturing, the radius r1 of the first chamfer 31 is set to be equal to the radius r2 of the second chamfer 32. Of course, depending on actual needs, the radius r1 of the first chamfer 31 can be set to be greater than or less than the radius r2 of the second chamfer 32. During assembly, the rounded edges provide better guidance. For automotive window glass, a larger radius r2 of the second chamfer, with its rounded edge transition, also helps the sealant or adhesive to fill and adhere more evenly, thereby improving the sealing effect.

[0059] In a preferred embodiment, such as Figures 3-5 As shown, it also includes step S4: setting a first chamfer 31 at the first cut edge 33c according to the radius value r1 and angle of the first chamfer 31; setting a second chamfer 32 at the second cut edge according to the radius value r2 and angle of the second chamfer 32.

[0060] In this embodiment, the positions of the first chamfer 31 and the second chamfer 32 are calculated based on the positions of the first cutting edge 33c and the second cutting edge, thereby completing the cutting and processing of the edge of the glass 1.

[0061] In a preferred embodiment, the method further includes step S5: measuring the actual minimum gap value c between the second chamfer 32 and the third surface 21a, and determining whether the actual minimum gap value c meets the requirements of the minimum gap design value DTS.

[0062] After obtaining the positions of the first cut edge 33c, the second cut edge, the cut surface 13, and the first chamfer 31 and the second chamfer 32 of the glass 1 using the glass profile design method of this application, the actual value of the minimum gap between the glass 1 and the sheet metal 2, that is, the actual value of the minimum gap between the second chamfer 32 and the third surface 21a, can be measured. The actual gap value is then compared with the design value DTS and its uniformity is checked to verify whether the method of finding the first cut edge 33c and the second cut edge of the glass 1 using this design method is accurate and effective.

[0063] In a preferred embodiment, step S5 includes: S51: Take points along the edge of glass 1 at specified intervals and measure the actual minimum gap value c between the second chamfer 32 and the third surface 21a at each point; S52: Compare and analyze the actual minimum clearance value c at each point, and compare the actual minimum clearance value c with the minimum clearance design value DTS.

[0064] To verify the glass profile design method, the minimum gap value c between the edge of glass 1 and sheet metal 2 is measured. Specifically, the minimum gap value c can be measured at certain intervals (e.g., 1cm) along the edge of glass 1, and the measured values ​​are recorded. The error is observed to see if it is controlled within the required range. These values ​​are then compared with the design value DTS. If the error is kept within the allowable range, the correctness of the glass profile can be verified.

[0065] In a preferred embodiment, specifically, the thickness of glass 1 is t=3.2mm; the radius of the first chamfer 31 is r1=1mm; the radius of the second chamfer 32 is r2=1mm; and the minimum clearance design value DTS between the second chamfer 32 and the third surface 21a is 2.65mm.

[0066] Of course, the glass 1 thickness t, the radius r1 of the first chamfer 31, the radius r2 of the second chamfer 32, and the minimum clearance design value DTS between the second chamfer 32 and the third surface 21a are not limited to the values ​​in the above embodiments. For example, the glass 1 thickness t is 5mm, the radius r1 of the first chamfer 31 is set to 1mm, the radius r2 of the second chamfer 32 is set to 1mm, and the minimum clearance design value DTS between the second chamfer 32 and the third surface 21a is set to 4mm. These parameters can be set according to the actual needs of the window assembly.

[0067] The dimensions of the radius r1 of the first chamfer 31 and the radius r2 of the second chamfer 32 conform to the typical processing capabilities of the cold bending or thermoforming process of glass 1, thereby avoiding stress concentration at sharp corners. For front and rear windshields bonded with adhesive, the size of the gap between glass 1 and sheet metal 2 is related to the construction quality and durability of the sealant. A uniform gap range that conforms to the design can ensure that the sealant forms an ideal sealing cross section, effectively providing waterproofing, dustproofing, and sound insulation.

[0068] by Figure 4 and Figure 5 For example, in this embodiment, the specific steps of the glass contour design method include: Input the following parameters into the simulation software: glass 1 thickness t = 3.2 mm; first chamfer 31 radius r1 = 1 mm; second chamfer 32 radius r2 = 1 mm; minimum clearance design value DTS between the second chamfer 32 and the third surface 21a = 2.65 mm; Offset the first surface 11a of glass 1: Offset the first surface 11a in a direction perpendicular to the first surface 11a and close to the third surface 21a, with an offset distance f satisfying: f=t−r2=2.2mm, thereby obtaining the first offset surface 11b; Offset the third surface 21a of sheet metal 2: Offset the third surface 21a in a direction perpendicular to the third surface 21a and close to the first surface 11a, with an offset distance h satisfying: h=DTS+r2=3.65mm, thereby obtaining the second offset surface 21b; An intersection line is obtained by the intersection of the first offset surface 11b and the second offset surface 21b. This intersection line defines the curve where the center O1 of the second chamfer 32 is located, which is the first curve 33a. The first curve 33a is offset by -f in a direction perpendicular to and close to the first surface 11a to cut the first surface 11a, thus obtaining the first offset curve 33b. By extrapolating and extending the first offset curve 33b along the direction of the first surface 11a by r2, the position of the first cutting edge 33c can be obtained, and then the position of the cutting surface 13 and the position of the second cutting edge can be obtained. Based on the radius value r1 and angle of the first chamfer 31, a first chamfer 31 is set at the first cut edge 33c; based on the radius value r2 and angle of the second chamfer 32, a second chamfer 32 is set at the second cut edge. Finally, points are taken along the edge of glass 1 at specified intervals of 1cm, and the actual minimum gap value c between the second chamfer 32 and the third surface 21a at each point is measured. The actual minimum gap value c at each point is compared and analyzed, and the actual minimum gap value c is compared with the minimum gap design value DTS to verify whether the actual gap between glass 1 and sheet metal 2 is consistent with the minimum gap design value DTS.

[0069] This application also provides a glass cutting method, which includes: determining a glass profile on a first surface 11a of glass 1 according to a glass profile design method, and cutting along the profile in a direction perpendicular to the first surface 11a.

[0070] First, the corresponding glass outline is drawn on the first surface 11a using a pen or other means to mark the subsequent cutting work and avoid deviations during the cutting process. Then, the glass 1 is cut along the outline using a laser or other means to quickly and accurately obtain the glass 1 with the preset outline.

[0071] This application also provides a method for assembling a vehicle window assembly, which includes: covering the opening of the vehicle window with glass 1, and filling the space between the glass 1 and the sheet metal 2 along the circumference of the glass 1.

[0072] The method for assembling the vehicle window assembly in this application ensures that the actual minimum gap between the glass 1 and the sheet metal 2 is equal everywhere. When filling the gap between the glass 1 and the sheet metal 2 with sealant, it is only necessary to move the glue gun at a uniform speed along the edge of the glass 1. There is no need to prolong the dwell time in areas with large gaps or reduce the dwell time in areas with small gaps, which would result in poor sealing or affect the appearance due to excessive or insufficient glue application.

[0073] During the assembly of the window assembly, after the glass 1 is placed on the sheet metal 2, the actual minimum gap value c between the glass 1 and the sheet metal 2 can be detected using a feeler gauge. Specifically, the actual minimum gap value c can be measured at certain intervals (such as 1cm) along the edge of the glass 1, and the measured values ​​can be recorded. The variance can be observed to see if it is controlled within the allowable range. These values ​​can then be compared with the design value DTS. If the error is kept within the allowable range, the correctness of the glass contour cutting can be verified.

[0074] This application also provides a vehicle including the aforementioned window assembly.

[0075] The vehicle of this application uses the window assembly of this application. The uniform gap between the glass 1 and the sheet metal 2 provides a stable and consistent filling space for the sealant or sealing strip, ensuring good sealing performance, effectively preventing moisture, dust and noise from entering, avoiding direct contact between the glass 1 and the sheet metal 2 or local stress concentration, and preventing the glass 1 from being squeezed, twisted or even broken due to vibration, thermal expansion and contraction or body torsion. Good sealing performance helps to improve sound insulation and noise reduction performance, reduce abnormal noises during driving, and provide a more comfortable and quiet in-vehicle environment for passengers.
