Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a sealing strip, a mold, an assembly method, a glass assembly, and a vehicle. Background Technology

[0002] Currently, most vehicle glass undergoes edge injection molding to form an edging portion that wraps around the glass edge and connects with the vehicle's weatherstripping to further seal the glass. Current weatherstripping typically consists of two parts: a soft portion that overlaps with the vehicle's sheet metal, and a rigid portion that assembles with the edging portion. Existing technology usually involves a groove on the side of the edging portion away from the glass, and the assembly part of the weatherstripping and the edging portion are manually engaged through this groove. This assembly process is cumbersome, wastes manpower and time, and reduces production efficiency. Furthermore, when the edging portion and the weatherstripping experience thermal expansion and contraction under certain conditions, mismatches can occur between the groove and the rigid portion of the weatherstripping, further increasing assembly difficulty.

The mold further includes a first slider and a second slider. The first slider slides in the first opening area along a first direction, and the second slider slides in the second opening area along a second direction. The first direction is the direction from the upper mold to the lower mold, and the second direction is the direction from the lower mold to the upper mold. The first slider and the second slider are used to extrude at least a portion of the assembly portion of the sealing strip from a first thickness to a second thickness before injection molding the material of the assembly object.

This eliminates the need for manual assembly of the sealing strip and the assembly object, saving manpower and reducing production costs. It also simplifies the assembly process, thereby reducing assembly time and improving production efficiency. Furthermore, since the structure is formed into a single unit through injection molding, the assembly difficulty of the sealing strip and the assembly object will not increase regardless of whether the edging portion and the sealing strip experience thermal expansion and contraction under certain conditions.

Detailed Implementation

[0022] 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 merely one embodiment 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.

[0023] In the description of the embodiments of this application, it should be understood that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, primarily refers to a physical structural connection; however, if specified, it may also include direct or indirect connections. The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0024] Please see Figure 1 , Figure 1 This is a schematic block diagram of a vehicle 100 according to an embodiment of this application. The vehicle 100 includes a glass assembly 200, which may be, but is not limited to, a sunroof, side window, or side window of the vehicle 100.

[0025] Please see Figure 2 , Figure 2This is a schematic diagram of a glass assembly 200' in the prior art. Traditionally, the sealing strip 300' is connected to the assembly object via a slot 501'. However, due to the vehicle body twisting during vehicle 100 operation, the sealing strip 300 may detach from the slot 501', resulting in a failure to achieve a seal between the glass assembly 200' and the vehicle body. In this application, the assembly object and the sealing strip 300 are directly fixed together via injection molding. Therefore, even if the vehicle body twists, the sealing strip 300 will not disconnect from the assembly object, thus improving the stability of the seal.

[0026] Please see Figure 3 , Figure 3 This is a schematic diagram of a glass assembly 200 according to an embodiment of this application. The glass assembly 200 includes a sealing strip 300, glass 400, and an edge-wrapping portion 500, the edge-wrapping portion 500 wrapping around the edge region of the glass 400.

[0027] Thus, the glass 400 achieves a sealing effect through the sealing strip 300 and the edge wrapping portion 500, and the soft part of the sealing strip 300 can overlap the sheet metal of the vehicle body, which enables the glass assembly 200 to have a sound insulation effect and good sealing performance, preventing liquids and dust from entering the body of the vehicle 100, and also improving the aesthetics of the glass assembly 200 installed in the vehicle 100.

[0028] The edge-wrapping portion 500 can be made of materials such as PU, which are suitable for injection molding and have high adhesion. In the prior art, the edge-wrapping portion 500' is assembled and connected to the sealing strip 300' through the slot 501'. This application differs from the prior art in that the edge-wrapping portion 500' is assembled and connected to the sealing strip 300' through the slot 501'. Instead, while the assembly object is formed through the injection molding process, the sealing strip 300, the assembly object, and the sealed object can be directly formed into an integral structure through the injection molding process.

[0029] Please see Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the sealing strip 300 in one embodiment of this application. Figure 5This is a schematic diagram of a sealing strip 300 according to another embodiment of this application. The sealing strip 300 includes a sealing structure 1 and an assembly part 2. The sealing structure 1 includes a first sealing part 11 and a second sealing part 12. The second sealing part 12 is connected to one side of the first sealing part 11. One side of the assembly part 2 is connected to the side of the first sealing part 11 opposite to the second sealing part 12. The assembly part 2 is used to assemble and connect with a corresponding assembly object to jointly seal the sealed object. At least a portion of the assembly part 2 is made of metal material, and the metal portion of the assembly part 2 is provided with one or more adhesive-reinforcing structures 21.

[0030] Therefore, unlike the prior art where the edge banding 500' is assembled and connected to the sealing strip 300' via the slot 501', this application allows the sealing strip 300, the assembly object, and the sealed object to be directly integrated into a single structure through injection molding while the assembly object is being formed. This eliminates the need for manual assembly of the sealing strip 300 and the assembly object, saving manpower and reducing production costs. It also simplifies the assembly process, thereby reducing assembly time and improving production efficiency. Furthermore, since the integrated structure is formed through injection molding, the assembly difficulty of the sealing strip 300 and the assembly object will not increase regardless of whether the assembly object and the sealing strip 300 experience thermal expansion and contraction under certain conditions.

[0031] Furthermore, since the injection-molded assembly object will be bonded to multiple surfaces of the assembly part 2, the surface area of ​​the assembly part 2 is increased by setting the adhesive gripping force enhancement structure 21, thereby increasing the area of ​​bonding between the assembly part 2 and the assembly object, and thus enhancing the bonding strength between the assembly object and the assembly part 2.

[0032] The object to be assembled is the edge-sealing portion 500, and the object to be sealed is the glass 400.

[0033] In some embodiments, the sealing structure 1 is made of materials such as EPDM or TPE, which are capable of good deformation to achieve the desired sealing effect.

[0034] Please see Figures 6-7 , Figure 6 This is a schematic diagram of the mold 600, sealing strip 300, and glass 400 in one embodiment of this application. Figure 7This is a schematic diagram of the combination of mold 600 and glass assembly 200 in one embodiment of this application. The mold 600 is applied to the sealing strip 300. The mold 600 includes an upper mold 5, a lower mold 6, a first slider 8, and a second slider 9. The upper mold 5 has a first cavity 51, and the lower mold 6 has a second cavity 61. The upper mold 5 and the lower mold 6 cooperate to form a processing cavity 7 that matches the shape of the sealing strip 300 and the object being sealed. The upper mold 5 has a first opening area 52 that communicates with the processing cavity 7. The lower mold 6 has a second opening area 62 that communicates with the processing cavity 7. The first slider 8 slides within the first opening area 52 along a first direction 10, and the second slider 9 slides within the second opening area 62 along a second direction 20. The first direction 10 is the direction from the upper mold 5 to the lower mold 6, and the second direction 20 is the direction from the lower mold 6 to the upper mold 5.

[0035] Please see Figures 8-10 , Figure 8 for Figure 4 Cross-sectional view at point AA Figure 9 for Figure 4 A schematic diagram of the assembly part 2 of the sealing strip 300 after it has been compressed. Figure 10 for Figure 9 A cross-sectional view at BB. The first slider 8 and the second slider 9 are used to extrude at least a portion of the assembly portion 2 of the sealing strip 300 from a first thickness to a second thickness, the first thickness being greater than the second thickness, before injection molding the material of the assembly object.

[0036] Please see Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the sealing strip 300 and glass 400 in one embodiment of this application before they are placed into the mold 600. Figure 12 for Figure 11 Cross-sectional view at CC. The sealing strip 300 and the sealed object are spaced apart within the machining cavity 7. The space between the sealing strip 300 and the sealed object is used for injection molding the material of the assembly object to form the assembly object, which connects the sealing strip 300 and the sealed object.

[0037] Specifically, first, the sealing strip 300 and the glass 400 are placed into the second cavity 61 of the lower mold 6, at which point the sealing strip 300 and the glass 400 will still be partially exposed. Then, the upper mold 5 and the lower mold 6 are fitted together, thereby forming the processing cavity 7 with the first cavity 51 and the second cavity 61. The entire sealing strip 300 and a portion of the glass 400 are located within the processing cavity 7, and the outer surfaces of the entire sealing strip 300 and the portion of the glass 400 can completely fit against the upper mold 5 and the lower mold 6. Then, the first slider 8 is placed into the first opening area 52, and the second slider 9 is placed into the second opening area 62. Pressure is applied to the first slider 8 and the second slider 9, causing the first slider 8 to move along the first direction 10 and causing the... The second slider 9 moves along the second direction 20, causing the first slider 8 to compress at least a portion of the assembly part 2, changing the thickness of the assembly part 2 from a first thickness to a second thickness. The at least portion of the assembly part 2 extends outwards during compression, causing the compressed portion of the assembly part 2 to undergo crushing deformation. Then, the first slider 8 and the second slider 9 exit the first opening area 52 and the second opening area 62, and pour the material of the assembly object into the space between the sealing strip 300 and the sealed object. This allows the assembly object, the sealed object, and the sealing strip 300 to be integrally molded through the injection molding process while simultaneously forming the assembly object.

[0038] Therefore, this application can directly form the sealing strip 300, the assembly object, and the sealed object into an integrated structure through injection molding while simultaneously forming the assembly object. This eliminates the need for manual assembly of the sealing strip 300 and the assembly object, saving manpower and reducing production costs. It also simplifies the assembly process, thereby reducing assembly time and improving production efficiency. Furthermore, since the integrated structure is formed through injection molding, the assembly difficulty of the sealing strip 300 and the assembly object will not increase regardless of whether the assembly object and the sealing strip 300 experience thermal expansion and contraction under certain conditions.

[0039] In some embodiments, the second slider 9 can be fitted to the assembly part 2, and at least a portion of the assembly part 2 can be squeezed by the first slider 8 alone, or at least a portion of the assembly part 2 can be squeezed by the first slider 8 and the second slider 9 together.

[0040] The portion of the assembly part 2 that is compressed includes at least the metal portion of the assembly part 2.

[0041] In some embodiments, the adhesive gripping enhancement structure 21 includes at least one of a hole 211 and a protrusion structure 212.

[0042] Since the material of the assembly object will be bonded to multiple surfaces of the assembly part 2 during injection molding to form an integral structure, the surface area of ​​the assembly part 2 can be increased by setting the adhesive gripping force enhancement structure 21, thereby increasing the bonding area between the assembly part 2 and the assembly object, and thus enhancing the bonding strength between the assembly object and the assembly part 2.

[0043] Please see Figure 13 and Figure 14 , Figure 13 for Figure 5 A schematic diagram of the assembly part 2 of the sealing strip 300 after it has been compressed. Figure 14 for Figure 13 Cross-sectional view at DD. In some embodiments, when the adhesive gripping force enhancement structure 21 includes a hole 211, the hole 211 is a through hole having at least one protrusion 2111, and / or, the peripheral region of the opening of the hole 211 is a slope, and one end of the slope is connected to the opening of the hole 211; when the adhesive gripping force enhancement structure 21 includes a protrusion structure 212, the protrusion structure 212 is a ridge or protrusion provided on the surface of the assembly part 2.

[0044] Therefore, by setting the hole 211, the material used in the assembly part 2 can be reduced to lower production costs, while the surface area of ​​the assembly part 2 can be increased, thereby enhancing the bonding area between the assembly part 2 and the assembled object. Furthermore, when the material of the assembled object is subsequently injected for injection molding, the material flows out through the hole 211, creating an interlocking structure between the portion of the assembled object within the hole 211 and the sealing strip 300, further strengthening the bond strength between the assembled object and the assembly part 2. When the hole 211 is a through hole with at least one protruding portion 2111, the material of the assembled object, when flowing into the hole 211, forms a more robust interlocking structure due to the presence of the protruding portion 2111, preventing the assembled object from detaching from the hole 211 and thus improving the mechanical interlocking strength between the assembly part 2 and the assembled object.

[0045] The inclined surface allows the injection material to flow more easily and quickly into the hole 211 during the injection molding of the assembly object, thereby increasing the bonding speed between the assembly object and the assembly part 2. Furthermore, the inclined surface may further increase the surface area of ​​the assembly part 2, which may further enhance the bonding strength between the assembly object and the assembly part 2. Moreover, when the material of the assembly object flows into the hole 211, it will form a large-headed anchor through the inclined surface, thereby improving the mechanical interlocking strength between the assembly part 2 and the assembly object.

[0046] Please see Figure 15 , Figure 15 This is a schematic cross-sectional view of the assembly part 2 in one embodiment of this application. In some embodiments, such as... Figure 14 and Figure 15 As shown, the hole 211 is a through hole with two protruding portions 2111. The two protruding portions 2111 are symmetrical about the axis of the hole 211. The left and right sides of the symmetry are defined by the left and right sides of the attached figure.

[0047] Please see Figure 16 , Figure 16 for Figure 15 A cross-sectional view of the assembly part 2 after it has been compressed. When the slider compresses the metal part of the assembly part 2, due to the Poisson effect during compression, the metal part of the assembly part 2 will undergo unidirectional compression, and the metal part of the assembly part 2 will expand in a direction perpendicular to the compression direction due to "volume conservation". Here, "unidirectional" in unidirectional compression refers to the overall direction including the first direction 10 and the second direction 20. The compression direction can be only the first direction 10, or it can include two directions with different directions, the first direction 10 and the second direction 20. Therefore, when the metal part of the assembly part 2 is compressed by the slider, the metal part of the assembly part 2 will shorten in the compression direction and lengthen in the direction perpendicular to the compression direction. As a result, after the metal part of the assembly part 2 is compressed, the diameter of the hole 211 will increase due to this phenomenon.

[0048] Therefore, after the metal part of the assembly part 2 is squeezed, the aperture of the hole 211 will expand, which will increase the surface area of ​​the material of the assembly object entering the hole 211 at the opening of the hole 211, and further enhance the bonding strength between the assembly object and the assembly part 2.

[0049] Among them, such as Figure 15 and Figure 16 As shown, the size of the protruding portion 2111 in the direction perpendicular to the compression direction also increases with the diameter of the hole 211.

[0050] Please see Figure 17 and Figure 18 , Figure 17 This is a cross-sectional schematic diagram of assembly part 2 in another embodiment of this application. Figure 18 for Figure 17 A cross-sectional view of assembly part 2 after it has been compressed. (See diagram below.) Figure 17 and Figure 18 As shown, the hole 211 is a through hole with a protruding portion 2111, which can be set at a desired position as needed. Furthermore, after the assembly part 2 is compressed, the diameter of the hole 211 increases, and the size of the protruding portion 2111 in the direction perpendicular to the compression direction also increases with the diameter of the hole 211.

[0051] Please see Figure 19 and Figure 20 , Figure 19 This is a cross-sectional schematic diagram of assembly part 2 in another embodiment of this application. Figure 20 for Figure 19 A cross-sectional view of the assembly part 2 after it has been compressed. In some embodiments, the hole 211 is a through hole with four protrusions 2111, each pair of protrusions 2111 being symmetrically arranged about the axis of the hole 211. Furthermore, after the assembly part 2 is compressed, the diameter of the hole 211 increases, and the dimensions of the protrusions 2111 in the direction perpendicular to the compression direction also increase with the diameter of the hole 211.

[0052] Please see Figure 21 and Figure 22 , Figure 21 This is a cross-sectional view of the assembly part 2 in another embodiment of this application. Figure 22 for Figure 21 The diagram shows a cross-sectional view of the assembly part 2 after it has been compressed. The hole 211 is a through hole with two protruding portions 2111, which are staggered based on the axis of the hole 211. Furthermore, after the assembly part 2 is compressed, the diameter of the hole 211 increases, and the size of the protruding portions 2111 in the direction perpendicular to the compression direction also increases with the diameter of the hole 211.

[0053] It is understood that the number of protruding parts 2111 is not limited to the number in the above embodiment, but may also be three, five, six, etc., and the position of the plurality of protruding parts 2111 can be arbitrarily set as needed, and the position of the protruding parts 2111 is not limited here.

[0054] Please see Figure 23 , Figure 23This is a cross-sectional schematic diagram of assembly part 2 in another embodiment of this application. In some embodiments, such as Figure 23 As shown, the hole 211 has a plurality of protruding portions 2111. Two of the protruding portions 2111 have a larger dimension in the direction perpendicular to the compression direction, while the other protruding portions 2111 have a smaller dimension in the direction perpendicular to the compression direction. The other protruding portions 2111 are arranged to extend in a helical direction based on the axis of the hole 211, and thus the helically arranged other protruding portions 2111 can be regarded as the internal thread of the hole 211.

[0055] In other embodiments, the hole 211 may only have a protrusion 2111 that can be regarded as an internal thread, without having a larger protrusion 2111 in a direction perpendicular to the compression direction.

[0056] When the hole 211 has an internal thread, the uniformity of the extrusion deformation of the assembly part 2 can be improved by 20% compared with a conventional hole 211.

[0057] In some embodiments, there are multiple protrusions 212, and the multiple protrusions 212 have the same height in the first direction 10, or at least two of the multiple protrusions 212 have different heights in the first direction 10.

[0058] In some embodiments, the side cross-section of the protrusion structure 212 is triangular, square, hemispherical, etc. When the assembly part 2 is squeezed, the protrusion structure 212 will contact the first slider 8 and the second slider 9 before other areas of the assembly part 2, and will deform before other areas of the assembly part 2, so that the assembly part 2 forms stepped wrinkles.

[0059] In some embodiments, when there are multiple protrusions 212, the multiple protrusions 212 can be distributed in rows and columns or irregularly.

[0060] In some embodiments, the side of the first sealing part 11 connected to the assembly part 2 is provided with one or more grooves 111, wherein the area where the one or more grooves 111 are located and the area where the assembly part 2 is connected are not in the same position.

[0061] Therefore, one or more grooves 111 provided on the first sealing part 11 can increase the surface area of ​​the side where the first sealing part 11 connects with the assembly part 2. As a result, when the material of the assembly object is injection molded, the contact area between the side and the material of the assembly object can be increased, which can increase the bonding force between the assembly object and the sealing strip 300, thereby enhancing the connection stability between the sealing strip 300 and the assembly object.

[0062] In some embodiments, the metal portion is made of aluminum alloy or copper.

[0063] In the prior art, the assembly part 2 is mostly made of EPDM (ethylene propylene diene monomer rubber) material with a density of 1.25-1.35 g / cm³, and the specific strength of the EPDM is 3-5 MPa·cm³ / g. However, the assembly part 2 made of aluminum alloy has a higher specific strength than the assembly part 2 made of the aforementioned EPDM material. Therefore, less aluminum alloy can be used to achieve the same load-bearing strength as the aforementioned EPDM material, thereby reducing the production cost of the sealing strip 300 and also reducing the weight of the sealing strip 300.

[0064] In some embodiments, the metal portion is made of an aluminum alloy with a density of 2.70 g / cm³ and a specific strength of 120-1503-5 MPa·cm³ / g. This specific strength is 24-30 times that of the aforementioned EPDM material. Therefore, the load-bearing capacity of a 0.5 mm thick aluminum alloy is equivalent to that of a 3 mm thick EPDM layer. This reduces the material used in the metal portion of the assembly part 2, thereby reducing the production cost and weight of the sealing strip 300. The wall thickness of the aluminum alloy assembly part 2 can be 0.3-0.8 mm, which reduces the cross-sectional area by 50%-70% compared to a conventional EPDM assembly part 2 (wall thickness 1.5-2.5 mm).

[0065] Among them, the assembly part 2 made of copper has greater ductility and deformation capacity than the assembly part 2 made of aluminum alloy, which can increase the contact area between the assembly part 2 and the assembly object after the assembly part 2 is compressed.

[0066] Please see Figure 24 , Figure 24This is a cross-sectional schematic diagram of the sealing strip 300 in another embodiment of this application. In some embodiments, the assembly part 2 includes a first assembly part 24, a second assembly part 25, and a third assembly part 26. The third assembly part 26 is connected to the first sealing part 11. The second assembly part 25 is located between the first assembly part 24 and the third assembly part 26. The first assembly part 24 is located on the side of the second assembly part 2 away from the first sealing part 11. The first assembly part 24 is made of a metal material, the second assembly part 25 is made of a metal composite material, and the material of the third assembly part 26 is the same as the material of the first sealing part 11.

[0067] Thus, the assembly part 2 gradually forms a trapezoidal functional layer from the side away from the sealing structure 1 to the side connected to the sealing structure 1, and the material used to make it gradually changes from a metal material to a material that is the same as the material used to make the first sealing part 11. This arrangement can reduce the stress at the connection between the assembly part 2 and the first sealing part 11 while achieving extrusion deformation, thereby improving the connection strength between the assembly part 2 and the first sealing part 11.

[0068] The first assembly part 24, the second assembly part 25, and the third assembly part 26 are formed into a single assembly part 2 by co-extrusion. The first assembly part 24, the second assembly part 25, and the third assembly part 26 are divided into main areas formed based on the majority of their respective manufactured materials. Figure 24 The dashed lines in the diagram represent the division of the main areas of the first assembly part 24, the second assembly part 25, and the third assembly part 26.

[0069] In some embodiments, the first assembly part 24 is made of 6061 aluminum alloy to ensure the bonding strength with the assembled object. The second assembly part 25 is an aluminum-PEEK (Polyether Ether Ketone) composite layer. PEEK material has good mechanical properties and good high temperature resistance. The third assembly part 26 is a modified EPDM material that is the same as the EPDM material used to make the sealing structure 1. This setting reduces the stress on the connection between the assembly part 2 and the first sealing part 11 and improves the connection strength between the assembly part 2 and the first sealing part 11.

[0070] In some embodiments, the surface of the assembly part 2 is provided with a coating, the material of which is nano-silica sol impregnated glass fiber.

[0071] Thus, by chemically reacting the coating with the metal part of the assembly part 2 and the material of the assembly object respectively, a chemical interlocking structure is achieved, thereby improving the bonding strength between the assembly part 2 and the assembly object.

[0072] In some embodiments, the assembly part 2 and the first sealing part 11 are an integral structure, or the sealing strip 300 further includes an adhesive component, and the assembly part 2 and the first sealing part 11 are connected by the adhesive component.

[0073] Thus, by injection molding, the assembly part 2 and the first sealing part 11 are integrated into one piece, thereby forming an integral structure. This can increase the connection strength between the assembly part 2 and the first sealing part 11. Alternatively, the assembly part 2 and the first sealing part 11 can be connected by the adhesive component, which facilitates subsequent injection molding connection with the assembly object.

[0074] In some embodiments, the assembly part 2 and the first sealing part 11 are connected by a high-temperature resistant adhesive such as an inorganic adhesive, and the adhesive part is a solid object after the adhesive has solidified.

[0075] Please see Figure 25 and Figure 26 , Figure 25 This is a schematic diagram of the assembly portion 2 of the sealing strip 300 in one embodiment of this application before it is compressed. Figure 26 for Figure 25 A schematic diagram of the assembly portion 2 of the sealing strip 300 after it has been compressed. In some embodiments, the assembly portion 2 includes a first end face 23 and a second end face disposed opposite to each other in the length direction 22 of the assembly portion 2, and the first sealing portion 11 includes a first sealing surface 112 and a second sealing surface disposed opposite to each other in the length direction 22 of the assembly portion 2, wherein the first sealing surface 112 is closer to the first end face 23 than the second sealing surface, the first sealing surface 112 has a first height based on the first end face 23 in a third direction 3, and / or the second sealing surface has a second height based on the second end face in a fourth direction 4, wherein the third direction 3 is the direction from the second end face to the first end face 23, and the fourth direction 4 is the direction opposite to the third direction 3; During the process of the first slider 8 and the second slider 9 pressing at least a portion of the assembly part 2 from a first thickness to a second thickness, at least a portion of the assembly part 2 extends along the third direction 3 and the fourth direction 4, and the first end face 23 and the second end face gradually approach the first sealing surface 112 and the second sealing surface, respectively.

[0076] Therefore, it is obvious that before at least a portion of the assembly part 2 is squeezed, a gap is left between the first end face 23 and the first sealing surface 112, and / or a gap is left between the second end face and the second sealing surface. This prevents the assembly part 2 from extending beyond the first sealing part 11 when the first slider 8 and the second slider 9 squeeze at least a portion of the assembly part 2, causing the assembly part 2 to extend and deform. This ensures that the glass assembly 200 can be assembled into the vehicle body and also ensures the aesthetic appearance of the glass assembly 200.

[0077] Please see Figure 27 , Figure 27 This is a flowchart of an assembly method according to an embodiment of this application. The assembly method is applied to the mold 600 as described above, and the method includes: S1: When the sealed object and the sealing strip are located in the processing cavity, and before the material of the assembled object is injection molded, at least a portion of the assembly portion of the sealing strip is squeezed from a first thickness to a second thickness by a first slider and a second slider, wherein the first thickness is greater than the second thickness; S2: Injecting the material of the assembly object into the space between the sealing strip and the sealed object to form the assembly object, the assembly object connecting the sealing strip and the sealed object.

[0078] Therefore, in this application, while forming the assembly object through injection molding, the sealing strip 300, the assembly object, and the sealed object can be directly integrated into a single structure through injection molding, eliminating the need for manual assembly of the sealing strip 300 and the assembly object. This saves manpower and reduces production costs, simplifies the assembly process, reduces assembly time, and improves production efficiency. Furthermore, since the structure is formed as a single unit through injection molding, the assembly difficulty of the sealing strip 300 and the assembly object will not increase regardless of whether the assembly object and the sealing strip 300 experience thermal expansion and contraction under certain conditions.

[0079] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Where there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other. Therefore, the scope of protection of this application should be determined by the scope of the claims.
