[0029] To make the above-mentioned objectives, features, and advantages of the present application clearer and easier to understand, specific embodiments of the present application will be described below in detail with reference to the accompanying drawings. The following description will include many specific details in order to provide a complete understanding of the present application. However, the present application can be implemented in many other forms different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application; therefore, the present application is not limited by the specific embodiments disclosed below.

[0030] As shown in Figure 1, in some embodiments, a glass molding assembly 10 is provided, which includes glass 11, molding 12, and weatherstrip 13. The molding 12 is provided on the edge of the glass 11. The weatherstrip 13 includes a first sealing portion 131 and a second sealing portion 132, the hardness of which the first sealing portion 131 is greater than that of the second sealing portion 132, and the first sealing portion 131 is connected between the second sealing portion 132 and the molding 12. A portion of either the first sealing portion 131 or the molding 12 is fitted into the other.

[0031] The weatherstrip 13 may be a co-extruded weatherstrip manufactured by a co-extrusion apparatus, or it may be manufactured by other processes, and is not particularly limited thereto.

[0032] In this application, when one object is fitted into the other object, it means that a part of one object is inserted into the other object. Specifically, one object is solidified by integral injection molding and fitted into the other object. Furthermore, in order to improve the reliability of the connection between the two fitted objects, in some embodiments, the portion of both the first seal portion 131 and the molding 12 that is fitted into the other object is the fitted portion, and the cross-sectional area of ​​the fitted portion tends to decrease in the direction away from the object to be fitted.

[0033] The glass molding assembly 10 according to the above solution ensures a more reliable connection between the weatherstrip 13 and the molding 12 by connecting the first seal portion 131, which has high hardness, to the molding 12. Furthermore, because the relationship between the first seal portion 131 and the molding 12 is partially fitted, the tensile force that can be withstood between the weatherstrip 13 and the molding 12 is large. The second seal portion 132, which has low hardness, comes into contact with the roof of the vehicle or other parts of the vehicle body, thus expanding the range of application. The method of combining the molding 12 and the weatherstrip 13 expands the range of application, ensures a sealing effect, and reduces water leakage after long-term use.

[0034] Specifically, as shown in Figures 2 to 5, in some embodiments, a portion of the molding 12 is fitted into the first sealing portion 131. The space in the first sealing portion 131 that accommodates the fitted portion of the molding 12 is the first T-shaped groove 1311. Because the T-shaped groove has a narrow opening and a wide groove bottom, it provides high tensile resistance and detachment prevention capabilities between the molding 12 and the first sealing portion 131.

[0035] In some embodiments, the difference between the opening width L11 and the groove bottom width L10 (not shown) of the first T-shaped groove 1311 is 2 mm to 5 mm. For example, the difference between the opening width L11 and the groove bottom width L10 of the first T-shaped groove 1311 is 3 mm or 4 mm. Furthermore, a large tensile force is required to ensure a secure connection between the molding 12 and the first seal portion 131 and to separate them.

[0036] As shown in Figure 3, in one embodiment, the opening width L11 of the first T-shaped groove 1311 is 2 mm to 5 mm, and the thickness L12 in the width direction of the opening of the first T-shaped groove 1311 in the portion of the first seal portion 131 where the first T-shaped groove 1311 is provided is 4 mm to 10 mm. The opening depth L13 of the first T-shaped groove 1311 is 2 mm to 3 mm, and the groove bottom depth L14 of the first T-shaped groove 1311 is 2 mm to 3 mm.

[0037] By optimizing the dimensions of the first T-shaped groove 1311, for example, the opening width L11, the groove bottom width L10, the opening depth L13, and the groove bottom depth L14, the molding 12, which is partially fitted into the first T-shaped groove 1311, is prevented from easily coming off.

[0038] In this application, the opening depth of the T-shaped groove refers to the depth of the space in the T-shaped groove where the width coincides with the opening width, and the groove bottom depth of the T-shaped groove refers to the depth of the space in the T-shaped groove where the width coincides with the groove bottom width.

[0039] Furthermore, in some other embodiments, as shown in Figures 6 to 8, a portion of the first seal portion 131 is fitted into the molding 12, and the space in the molding 12 that accommodates the fitted portion of the first seal portion 131 is a second T-shaped groove (not shown).

[0040] Similarly, as shown in Figure 6, the one-sided difference L212 between the opening width L21 and the groove bottom width L22 (not shown) of the second T-shaped groove is 0.5 mm to 3 mm. For example, the one-sided difference between the opening width L21 and the groove bottom width L22 of the second T-shaped groove is 1 mm or 2 mm.

[0041] Specifically, in one embodiment, as shown in Figure 6, the opening width L21 of the second T-shaped groove is 4 mm to 12 mm, the opening width L21 of the second T-shaped groove is 1 mm to 6 mm smaller than the groove bottom width L22 (not shown) of the second T-shaped groove, the opening depth L23 of the second T-shaped groove is 1 mm to 4 mm, and the groove bottom depth L24 of the second T-shaped groove is 1 mm to 3 mm.

[0042] Furthermore, in some embodiments, as shown in Figure 6, the minimum distance L5 between the second seal portion 132 and the molding 12 is 3 mm to 10 mm. In this way, the support capacity of the first seal portion 131 is ensured, and the first seal portion 131 can be appropriately bent as needed during assembly. After the glass molding assembly 10 is installed in place, the first seal portion 131 elastically recovers to the extended state shown in the figure, improving the convenience of assembly.

[0043] Specifically, in one embodiment, as shown in Figures 2 and 3, a portion of the molding 12 is fitted into the first sealing portion 131, and the depth L15 of the first sealing portion 131 is 6 mm to 12 mm in the direction of the distance between the second sealing portion 132 and the glass 11.

[0044] As shown in Figures 1 to 10, in some embodiments, a positioning groove 1312 is provided on the surface of the first sealing portion 131 that is not in direct contact with the molding 12 and is not in direct contact with the second sealing portion 132.

[0045] As shown in Figures 4, 5, 7, 8, and 10, the positioning groove 1312 can be used to position the molding 12 during injection molding, and the mold 20 is partially inserted into the positioning groove 1312 to limit the position of the weatherstrip 13 in the mold 20. On the other hand, by providing the positioning groove 1312, the first seal portion 131 is more easily bent and deformed during assembly work where it is necessary to bend the first seal portion 131.

[0046] Specifically, in one embodiment, as shown in Figure 6, the notch width L6 of the positioning groove 1312 is 1 mm to 5 mm, and the depth L7 of the positioning groove 1312 is 2 mm to 4 mm.

[0047] In another embodiment, as shown in Figure 3, the notch width L16 of the positioning groove 1312 is 1 mm to 5 mm, and the depth L17 of the positioning groove 1312 is 2 mm to 4 mm.

[0048] In some embodiments, the first seal portion 131 is made of PP (polypropylene), ABS (Acrylonitrile Butadiene Styrene), TPE (Thermoplastic Elastomer), or PVC (Polyvinyl chloride).

[0049] The second seal portion 132 is made of TPE material, EPDM (Ethylene Propylene Diene Monomer) material, or PVC material. The material of the second seal portion 132 is compatible with the material of the first seal portion 131.

[0050] Molding 12 uses PU (polyurethane), PP, PVC, TPE, or ABS material.

[0051] The first seal portion 131 and the molding 12 are connected by integral injection molding.

[0052] Furthermore, as shown in Figure 1, in some embodiments, the second seal portion 132 has a cavity 1321, and the cavity 1321 extends along the length of the weatherstrip 13.

[0053] In another embodiment, a vehicle is provided that includes a glass molding assembly 10 according to any one embodiment of the present application.

[0054] Since the vehicle relating to the above solution uses the glass molding assembly 10 according to any embodiment of the present application, it has high compatibility and airtightness, and water leakage after long-term use is reduced.

[0055] In yet another embodiment, a method for manufacturing a glass molding assembly 10 is provided, the glass molding assembly 10 including a weatherstrip 13, wherein the hardness of the first seal portion 131 is greater than that of the second seal portion 132, the second seal portion 132 has a cavity 1321, and the cavity 1321 extends along the longitudinal direction of the weatherstrip 13. Of course, the glass molding assembly 10 manufactured by the above manufacturing method may be the glass molding assembly 10 described in any of the above embodiments.

[0056] This manufacturing method includes, as shown in Figures 4, 5, 7, 8 and 10, step S1: placing the glass 11 and weatherstrip 13 into a mold 20, positioning the first seal portion 131 with the mold 20, and pressing the second seal portion 132 in the direction closer to the first seal portion 131, thereby pressing and deforming the second seal portion 132 and compressing the cavity 1321 so that the glass 11, the first seal portion 131 and the mold 20 surround each other to form an injection-molded cavity; step S2: injecting molding material into the injection-molded cavity; and step S3: removing the mold 20 after the molding material has solidified, allowing the second seal portion 132 to elastically recover to the initial state of the cavity 1321.

[0057] The glass molding assembly 10 manufactured by the manufacturing method of the glass molding assembly 10 according to the above solution combines the molding 12 and the weatherstrip 13, resulting in a wide range of applications, high sealing performance, and reduced water leakage after long-term use. Furthermore, during manufacturing, the overall mold 20 presses the second seal portion 132 in the direction closer to the first seal portion 131, causing the second seal portion 132 to be pressed and deformed, compressing the cavity 1321. As a result, during injection molding, the stress performance of the weatherstrip 13 is strong, the shape is stable, and the connection reliability between the injection-molded molding 12, glass 11, and weatherstrip 13 is high.

[0058] As shown in Figures 1, 2, 6, and 9, after the molding material has solidified and been demolded, the second seal portion 132 can elastically recover to the initial state of the cavity 1321.

[0059] Furthermore, in some embodiments, as shown in Figures 4, 5, 7, 8, and 10, the surface of the first seal portion 131 that is provided along the longitudinal direction and in direct contact with the overall mold 20 is the first main surface 1313, and the overall mold 20 and the first main surface 1313 are interlocked at least in some positions. The overall mold 20 can press against the first seal portion 131 and fix its position, and because the overall mold 20 and the first seal portion 131 are tightly fitted together, it is possible to prevent molding material from flowing into the gap between the overall mold 20 and the first seal portion 131.

[0060] As shown in Figures 7 and 8, triangular projections 23 are provided at some positions on the overall mold 20 that face the first main surface 1313, and after the weatherstrip 13 is assembled to the overall mold 20, these triangular projections 23 are interlocked with the first main surface 1313.

[0061] Specifically, in some embodiments, the interference fit of the interlocking portion is 0.05 mm to 0.3 mm. This prevents the molding material from flowing into the gap between the overall mold 20 and the first seal portion 131, and also prevents the first seal portion 131 from being pressed and damaged.

[0062] As shown in Figures 4, 5, 7, 8, and 10, during injection molding, the gap between the main mold 20 and the first seal portion 131 is reinforced by an interlocking fit, which more reliably defines the position of the first seal portion 131 and prevents the molding material from flowing into the gap between the first seal portion 131 and the main mold 20. In the first seal portion 131, the surface on which the positioning groove 1312 is provided and the surface that is reinforced with the main mold 20 face each other. Furthermore, in some embodiments, these two surfaces are located between the second seal portion 132 and the injection molding cavity for forming the molding 12. The overall mold 20 is partially inserted into the positioning groove 1312, providing upward and lateral support to the first seal portion 131, thereby allowing the overall mold 20 to be tightly fitted onto the first seal portion 131 and, by applying a pressing force to the second seal portion 132, the second seal portion 132 can be deformed in a direction closer to the first seal portion 131.

[0063] Specifically, as shown in Figures 4, 5, 7, 8, and 10, the overall mold 20 includes an upper mold 21 and a lower mold 22 that are engageable with each other, the lower mold 22 being located below the glass 11 and weatherstrip, and the upper mold 21 being located above the glass 11 and weatherstrip 13. The lower mold 22 is partially inserted into a positioning groove 1312 to provide upward and lateral support to the first seal portion 131, thereby the upper mold 21 is tightly fitted onto the first seal portion 131, and the upper mold 21 applies a pressing force to the second seal portion 132, causing the second seal portion 132 to deform in a direction closer to the first seal portion 131.

[0064] Furthermore, as shown in Figures 4, 5, 7, 8, and 10, in some embodiments, when the overall mold 20 presses the second seal portion 132, the pressing force applied to the second seal portion 132 may be decomposed into a first component perpendicular to the plane defined by the glass 11 and a second component parallel to the plane defined by the glass 11. The plane defined by the glass 11 refers to the plane parallel to the side surface of the glass 11 with the largest area, if the glass 11 is in a flat plate shape.

[0065] In some embodiments, when injecting the material for the mold 12 into the injection molding cavity, the greater the injection molding pressure the cavity wall of the injection molding cavity experiences, the greater the degree to which the overall mold 20 presses against the second seal portion 132 in advance.

[0066] As shown in Figures 4 and 7, in some embodiments, the injection molding pressure in the injection molding cavity is less than 5 MPa, or the minimum distance between the second seal portion 132 and the injection molding cavity is 5 mm or more. As a result, the second seal portion 132 is pressed and deformed, but the cavity 1321 is not pressed and completely disappears, leaving a gap, and the cavity walls of the cavity 1321 do not adhere to each other. In this case, PU material can be used for the molding 12.

[0067] In other embodiments, as shown in Figures 5, 8 and 10, in step S1, after the second seal portion 132 is pressed and deformed, some of the cavity walls of the cavity 1321 are bonded together, and step S2 is a step of injecting PP material, PVC material, TPE material or ABS material into the injection molding cavity, the step of injecting the injection molding pressure in the injection molding cavity to be greater than 5 MPa.

[0068] Alternatively, in step S1, after the second seal portion 132 is pressed and deformed, some of the cavity walls of the cavity 1321 are bonded together, and step S2 includes injecting PU material, PP material, PVC material, TPE material, or ABS material into the injection-molded cavity, wherein the minimum distance between the second seal portion 132 and the injection-molded cavity is less than 5 mm.

[0069] In other words, if the injection molding pressure in the injection molding cavity is high, for example, greater than 5 MPa, or if the minimum distance between the second seal portion 132 and the injection molding cavity is less than 5 mm, the second seal portion 132 is pressed until some of the cavity walls of the cavity 1321 are pressed together. Furthermore, as shown in Figures 2, 6, and 9, in some embodiments, the surface of the first seal portion 131 that is in direct contact with the second seal portion 132 is the second principal plane 1314, and the angle a between the second principal plane 1314 and the glass 11 is 98° to 130°.

[0070] As shown in Figure 10, the overall mold 20 presses the second seal portion 132 until some of the cavity walls of the cavity 1321 are bonded together, and the pressing force from the overall mold 20 is directly transmitted to the second main plane 1314 through the bonded cavity walls. Since the angle a between the second main plane 1314 and the glass 11 is 98° to 130°, when clamping or demolding the upper mold 21 and lower mold 22 included in the overall mold 20, the upper mold 21 can easily move vertically relative to the second seal portion 132 at the angle shown in Figure 10, improving the convenience of clamping and demolding. If angle a is 90°, the frictional force between the upper mold 21 and the second seal portion 132 is large, and the upper mold 21 has difficulty pressing the second seal portion 132. If angle a is too large, the horizontal component of the force applied by the upper mold 21 to the second main plane 1314 is small.

[0071] In the embodiment shown in Figure 9, the minimum distance L33 between the second seal portion 132 and the molding 12 is 2 mm to 5 mm.

[0072] As shown in Figure 9, in this embodiment, the notch width L36 of the positioning groove 1312 is 1.5 mm to 4 mm, and the depth L37 of the positioning groove 1312 is 2 mm to 4 mm.
