AI Technical Summary
In the existing technology, the stability of flush-mounted door and window assemblies is poor. They are prone to loosening or detachment after a period of use or under external force. This is mainly due to the small distance between the guide rail and the inner surface of the corner window glass, resulting in thin edging, insufficient injection molding material, and stagnation.
The edging design is made of one-piece injection molding. The edging includes a main section and a transverse section. The guide rail has a first injection port and the transverse section has a second gate. The edging material is injected through these injection ports to form an integral structure, ensuring that the edging is evenly filled in the gap between the guide rail and the corner window glass, thus enhancing the connection stability.
This improves the stability of the connection between the guide rail and the corner window glass, avoids defects such as insufficient or retained edge material, ensures that the outer surface of the corner window glass is flush with the outer surface of the lift glass, and enhances the product's appearance.

Abstract
Description
Technical Field
[0001] This application relates to the field of glass edging technology, and in particular to a vehicle, a flush-mounted corner window assembly and its processing method. Background Technology
[0002] With the development of glass edging technology, corner windows and lift windows in related technologies are usually designed to be flush, meaning the outer surfaces of the corner window and lift window are on the same plane. The lift window slides within a guide rail groove, and the guide rail is integrally injection-molded with the corner window through the edging. The edging wraps around the edge of the corner window or connects it to the guide rail. When the edging wraps around the edge of the corner window, it protrudes from the outer surface of the corner window and is not flush with it; therefore, this structural method has gradually been phased out. However, by integrally injection-molding the edging between the guide rail and the corner window, the edging is placed on the inner surface of the corner window, resulting in a flush design between the outer surfaces of the corner window and the lift window.
[0003] However, after the edge-wrapping is integrally injection molded and connected between the guide rail and the corner window glass, the two opposing surfaces of the edge-wrapping are connected and fixed to the corner window glass and the guide rail respectively. The resulting flush door and corner window assembly has poor stability and is prone to loosening or even detachment after a period of use or under external force. Summary of the Invention
[0004] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a vehicle, a flush-mounted door and corner window assembly and its processing method, which can improve the connection stability between the guide rail and the corner window glass.

[0008] The edging includes a main body segment integrally injection molded on the inner surface of the corner window glass and the spacer between the guide rail, and two transverse segments integrally injection molded on the corner window glass and respectively connected to the opposite ends of the main body segment. The main body segment is provided with a first gate corresponding to the position of the first injection port, and each of the two transverse segments is provided with a second gate.
[0009] In one embodiment, the first injection port is located at the middle of the main body segment along its length.

[0011] In one embodiment, when the distance between the surface of the filling part and the corner window glass is less than the distance between the side of the first track plate away from the edge and the corner window glass, the height difference S between the surface of the filling part and the side of the first track plate away from the edge is 1mm-10mm.
[0012] In one embodiment, the guide rail is provided with at least one abutment portion that abuts tightly against the inner surface of the corner window glass.
[0013] In one embodiment, the abutment is provided as a protrusion, boss, bulge, or post; and / or, the abutment is provided as a plurality of abutments arranged at intervals on the guide rail.
[0014] In one embodiment, the guide rail has a first wall on one side along its length direction, and the main body segment has a first side surface on one side along the length direction, with the first wall and the first side surface being flush; and / or, the guide rail has a second wall on the other side along its length direction, and the main body segment has a second side surface on the other side along the length direction, with the second wall and the second side surface being flush.
[0015] In one embodiment, the guide rail is provided with a groove, the inner wall of the groove is provided with a limiting part, and the groove is also provided with a sealing strip, the sealing strip being provided with an anti-detachment part for limiting and cooperating with the limiting part.
[0016] In one embodiment, the guide rail has a reinforcing portion on the side facing the corner window glass that corresponds to the limiting portion.
[0017] In one embodiment, the area between the limiting part and the bottom wall of the groove corresponds to the position of the reinforcing part.
[0018] In one embodiment, the flush-mounted corner window assembly further includes a lift-up glass and a movable bracket connected to the lift-up glass; the guide rail is provided with a groove, the groove is provided with a sealing strip, and the movable bracket is slidably disposed in the sealing strip.
[0019] In one embodiment, the outer surface of the lift glass is flush with the outer surface of the corner window glass.
[0020] A method for processing the flush-type corner window assembly, the method comprising the following steps:
[0021] A molding die is provided, the corner window glass and the guide rail are placed into the molding die, and a mold closing action is performed, so that the inner surface of the corner window glass and the guide rail form a gap area, and the gap area is sealed by the molding die to form an injection cavity.
[0022] Fluid-form edge-binding material is injected into the injection cavity from the first injection port and the two second injection ports corresponding to the positions of the second gates, respectively.
[0023] After the edge-binding material has solidified and formed, the mold opening action is performed.

Furthermore, the edging does not protrude from the outer surface of the corner window glass, ensuring that the outer surface of the corner window glass is flush with the outer surface of the lift-up window, enhancing the product's appearance. In addition, because a first injection port is provided on the guide rail, the two transverse sections are each correspondingly molded. The mold has a second injection port. During the manufacturing process, the edging material can be injected into various positions in the gap area between the guide rail and the inner surface of the corner window glass through the first injection port and the two second injection ports respectively. This ensures that each position in the gap area is filled with edging material. In other words, it can avoid defects such as material shortage and retention caused by the edging material not flowing from the area between the transverse section and the inner surface of the corner window glass and filling the area between the main section and the inner surface of the corner window glass when the gap between the guide rail and the inner surface of the corner window glass is too small. This can improve the connection stability between the guide rail and the inner surface of the corner window glass. Attached Figure Description

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0039] As described in the background section, the flush-fit corner window assembly obtained in the related technology has poor stability. It is prone to loosening or even detachment after a period of use or under external force. The inventors have found that the reason for this problem is that in the injection molding process of the related technology, the edge material is generally injected into the cavity formed by the corner window glass and the mold from the gate positions designed on the upper and lower horizontal sections of the edge. However, the design space between the guide rail, the corner window glass, and the groove is relatively limited, which makes the distance between the guide rail and the inner surface of the corner window glass relatively small, resulting in a relatively thin edge. Especially when the vertical dimension of the corner window glass is large and the length of the guide rail is long, problems such as insufficient injection material and stagnation are prone to occur between the guide rail and the inner surface of the corner window glass. As a result, the flush-fit corner window assembly has poor stability and is prone to loosening or even detachment after a period of use or under external force.
[0040] Based on the above reasons, this application provides a vehicle, a flush-mounted corner window assembly and its processing method, which can improve the connection stability of the guide rail and the corner window glass.
[0041] See Figures 1 to 4 , Figure 1 The diagram shows the structure of the edging 20 combined with the corner window glass 10. Figure 2 The diagram shows the structure of the combination of the lift-up glass 50, the guide rail 30, and the corner window glass 10. Figure 2 The movable glass 50 shown in the image is only a partial structure. Figure 3 It shows Figure 2 Sectional view of the structure at point AA Figure 4 A structural diagram of the guide rail 30 is shown. One embodiment of this application provides a flush-mounted corner window assembly, which includes a corner window glass 10, a edging 20, and a guide rail 30. The guide rail 30 is spaced apart from the inner surface of the corner window glass 10, and a first injection port 301 is provided on the guide rail 30. The edging 20 includes a main body section 21 integrally injection-molded in the spacer region 40 between the inner surface of the corner window glass 10 and the guide rail 30, and two transverse sections 22 integrally injection-molded on the corner window glass 10 and respectively connected to the opposite ends of the main body section 21. The main body section 21 has a first gate corresponding to the position of the first injection port 301, and each of the two transverse sections 22 has a second gate.
[0042] It should be noted that the inner surface of the corner window glass 10 refers to the side of the corner window glass 10 facing the inside of the vehicle, while the outer surface of the corner window glass 10 refers to the side of the corner window glass 10 facing the outside of the vehicle.
[0043] The aforementioned flush-fit corner window assembly, because the edging 20 includes a main section 21 integrally injection-molded on the inner surface of the corner window glass 10 and the spacer area 40 between the guide rail 30, and two transverse sections 22 integrally injection-molded on the corner window glass 10 and respectively connected to the opposite ends of the main section 21, can achieve the corner window glass 10, the edging 20 and the guide rail 30 forming an integral structure. Furthermore, the edging 20 does not protrude from the outer surface of the corner window glass 10, ensuring that the outer surface of the corner window glass 10 is flush with the outer surface of the lift glass 50, enhancing the product's appearance. In addition, because the guide rail 30 has a first injection port 301, and each of the two transverse sections 22 corresponds to a molding die 6... The part 0 is provided with a second injection port. During the manufacturing process, the edge-wrapping material 20 can be injected into each position of the gap area 40 between the guide rail 30 and the inner surface of the corner window glass 10 through the first injection port 301 and the two second injection ports respectively. This ensures that each position of the gap area 40 is filled with edge-wrapping material 20. In other words, it can avoid defects such as material shortage and retention caused by the difficulty of the edge-wrapping material flowing from the area between the transverse section 22 and the inner surface of the corner window glass 10 and filling the area between the main body section 21 and the inner surface of the corner window glass 10 when the gap between the guide rail 30 and the inner surface of the corner window glass 10 is too small. This can improve the connection stability between the guide rail 30 and the inner surface of the corner window glass 10.
[0044] In some embodiments, the first injection port 301 may be, but is not limited to, an open opening disposed on the guide rail 30, or a closed opening, or other forms, depending on actual needs. An open opening means that, starting from a point on the port wall, movement along the port wall in a single direction from that point cannot return to the starting point; conversely, a closed opening means that, starting from a point on the port wall, movement along the port wall in a single direction from that point can return to the starting point. Furthermore, the second injection port is disposed on the molding die 60, specifically, for example, as the outlet of the injection tube of the molding die 60, or, for example, as the outlet of the injection channel 64 of the molding die 60, or other forms. The shape of the second injection port is similar to that of the first injection port 301, and will not be described further here.
[0045] Optionally, the first injection port 301 and the second injection port are each independently configured with various regular shapes, including but not limited to U-shaped ports, semi-circular ports, circular ports, semi-elliptical ports, elliptical ports, polygonal ports, and other irregular shapes. The specific shapes can be flexibly adjusted and set according to actual needs. In this embodiment, the first injection port 301 is specifically configured as a U-shaped port, for example... Figure 4 As shown.
[0046] In some embodiments, after the edge-wrapping material 20 is injected into the spacer region 40 through the first injection port 301, the edge-wrapping material 20 also fills the first injection port 301 and is integrally injection molded into the first injection port 301. In the molded product, a filling portion 211 can be observed at the first injection port 301. A gate residue, i.e., the first gate, is formed on the surface 2111 of the filling portion 211 at the first injection port 301 at the position where it contacts the injection channel 64. Similarly, a gate residue, i.e., the second gate, can also be observed at the position corresponding to the second injection port on the transverse section 22.
[0047] In some embodiments, the edging 20 includes, but is not limited to, at least one of the following plastic materials: PP (Polypropylene), ABS (Acrylonitrile Butadiene Styrene plastic), PC (Polycarbonate), PA (Polyamide), SAN (acrylonitrile-styrene copolymer), PBT (Polybutylene terephthalate), POM (Polyformaldehyde), PVC (Polyvinyl chloride), and PU (Polyurethane).
[0048] Please see Figures 1 to 4 In one embodiment, the first injection port 301 is located at the middle portion of the guide rail 30 along its length direction L. The first gate is correspondingly located at the middle portion of the guide rail 30 along its length direction L. Specifically, the first gate is located at the exact center of the guide rail 30 along its length direction L, for example, [details omitted]. Figure 1 As shown at point P1. Thus, after the fluid-state edge-binding material 20 is injected from the first gate, it flows along the opposite ends of the guide rail 30, improving the uniformity of the edge-binding material's dispersion and ensuring it fills the gap region 40 between the guide rail 30 and the inner surface of the corner window glass 10. Furthermore, the second gate can be arranged at any position on the transverse section 22. Specifically, the positions of the two second gates on the two transverse sections 22 are, for example... Figure 1 As shown at point P2, after the fluid-state edge-wrapping material 20 is injected from the second injection port corresponding to the second gate position, a portion of the edge-wrapping material 20 will be attached to the inner surface and / or outer surface of the corner window glass 10, and another portion can flow and fill the gap area 40 between the guide rail 30 and the inner surface of the corner window glass 10.
[0049] Please see Figure 4 and Figure 5 , Figure 5This diagram illustrates the process of injecting the edge-wrapping material 20 into the spacer region 40 through the injection channel 64 and the first injection port 301 during injection molding. The injection channel 64 is located within the molding die 60; other structures of the molding die 60 are concealed and not shown. In some embodiments, the guide rail 30 includes a first track plate 31 interconnected with the main body segment 21. The first injection port 301 is formed on the first track plate 31, and the main body segment 21 has a filling portion 211 that fills the first injection port 301. A first gate is formed on the surface 2111 of the filling portion 211. The surface 2111 of the filling portion 211 is flush with the side surface 311 of the first track plate 31 that faces away from the main body segment 21.
[0050] Please see Figure 4 and Figure 6 , Figure 6 This diagram illustrates the process of injecting the edge-wrapping material 20 into the spacer region 40 through the injection channel 64 via the first injection port 301 during injection molding. In other embodiments, the surface 2111 of the filling portion 211 and the side 311 of the first track plate 31 that faces away from the main body section 21 may not be flush. Specifically, the distance between the surface 2111 of the filling portion 211 and the corner window glass 10 is smaller than the distance between the side 311 of the first track plate 31 that faces away from the main body section 21 and the corner window glass 10. In other words, there is a height difference S between the surface 2111 of the filling portion 211 and the side 311 of the first track plate 31 that faces away from the main body section 21. Optionally, the height difference S between the surface 2111 of the filling part 211 and the side 311 of the first track plate 31 that is away from the main body section 21 is, but not limited to, 1mm-10mm, specifically, 1mm, 3mm, 5mm or 10mm, so that the protrusion height of the surface 2111 of the filling part 211 at the first injection port 301 is reduced, which is used to absorb the edge-sealing material 20 remaining at the first gate of the surface 2111 of the filling part 211, thereby reducing or even avoiding the noise caused by the moving bracket 70 moving in the slide 34 during the movement of the lifting glass 50.
[0051] Please see Figure 3 and Figure 4 In some embodiments, the guide rail 30 further includes a second track plate 32 connected to the first track plate 31 and a third track plate 33 connected to the second track plate 32. The first track plate 31, the second track plate 32 and the third track plate 33 together form a groove 34.
[0052] Please see Figure 3 and Figure 4In one embodiment, the guide rail 30 is provided with at least one abutment portion 35. The abutment portion 35 abuts tightly against the inner surface of the corner window glass 10. In this way, by abutting tightly against the inner surface of the corner window glass 10, the abutment portion 35 plays a precise positioning role, which can make the distance between the guide rail 30 and the inner surface of the corner window glass 10 at a preset size, that is, the thickness of the main body segment 21 can be precisely controlled; in addition, the molding mold 60 can also abut tightly against the inner surface of the corner window glass 10 and the guide rail 30, thereby improving the defects of glue overflow and flash.
[0053] In some embodiments, the abutment portion 35 includes, but is not limited to, various protruding structures such as protrusions, bosses, bulges, or pillars.
[0054] In some embodiments, the abutment portion 35 is provided as a single abutment portion 35, which abuts against the inner surface of the corner window glass 10.
[0055] In other embodiments, the abutment portion 35 is not limited to one; for example, it can be multiple portions arranged at intervals on the guide rail 30. The abutment portions 35 are arranged sequentially at intervals along the length L of the guide rail 30, ensuring that the distance between each part of the guide rail 30 and the inner surface of the corner window glass 10 remains consistent, thereby achieving high consistency in the thickness of the edging 20 along the length L.
[0056] In some other embodiments, the abutment portion 35 may be two, located on opposite sides of the first injection port 301.
[0057] Please see Figure 4 In some embodiments, the abutment portion 35 is specifically provided, for example, on the side 311 of the first track plate 31 facing the corner window glass 10.
[0058] It should be noted that the "abutting part 35" can be "a part of the guide rail 30", that is, the "abutting part 35" and "other parts of the guide rail 30" are integrally molded; or it can be an independent component that can be separated from "other parts of the guide rail 30", that is, the "abutting part 35" can be manufactured independently and then combined with "other parts of the guide rail 30" to form a whole.
[0059] Please see Figure 4In some embodiments, the abutment portion 35 may include at least one first abutment portion 35135, which directly abuts against the inner surface of the corner window glass 10 to achieve precise positioning of the guide rail 30; or it may include at least one second abutment portion 35235, which indirectly abuts against the inner surface of the corner window glass 10. Specifically, the second abutment portion 35235 abuts against the slider of the forming mold 60, so that the slider of the forming mold 60 abuts tightly against the inner surface of the corner window glass 10 to achieve precise positioning of the guide rail 30.
[0060] Please see Figure 3 , Figure 7 and Figure 8 , Figure 8 This diagram illustrates the structure of the molding die 60 during injection molding according to an embodiment of this application, where the die is in close contact with the first wall surface 36 and the second wall surface 37. In some embodiments, the guide rail 30 has a first wall surface 36 on one side along its length direction L, and the main body segment 21 has a first side surface 212 on one side along its length direction L. The first wall surface 36 and the first side surface 212 are flush. Thus, during injection molding, the first pressing surface 62 of the molding die 60 presses tightly against the first wall surface 36, simultaneously sealing one side of the interval area 40. After the main body segment 21 is injection molded, the first side surface 212, which is flush with the first wall surface 36, is obtained, preventing material overflow and flash defects in the main body segment 21. Furthermore, since the main body segment 21 is not exposed outside the area of the first wall surface 36, the volume of the cavity is relatively small, making it prone to material shortage and retention defects. By adding glue through the first injection port 301, material shortage and retention defects can be significantly improved. In addition, there is no need to install an interior panel to cover the edging 20, which means that the interior panel in the related technology can be omitted, and the guide rail 30 can be directly exposed in the vehicle interior as a decorative surface. Since there is no need to install an interior panel, the structure is simplified and the cost is reduced.
[0061] Please see Figure 3 , Figure 7 and Figure 8 In some embodiments, the guide rail 30 has a second wall surface 37 on its other side along its length direction L, and the main body segment 21 has a second side surface 213 on its other side along its length direction L. The second wall surface 37 and the second side surface 213 are flush. Thus, the function is similar to that of the first wall surface 36 and the first side surface 212 being flush, and will not be described further.
[0062] Please see Figure 3 , Figure 7 and Figure 8In one specific embodiment, the first wall surface 36 is close to the opening of the groove 34, and the second wall surface 37 is away from the opening of the groove 34. No injection ports are provided on the second side surface 213 and the second wall surface 37, thereby preventing the gate on the corresponding edge 20 surface from being exposed and affecting the appearance. Furthermore, when the second side surface 213 and the second wall surface 37 are flush, the visible area of the corner window glass 10 can be increased.
[0063] In some embodiments, an interior panel may also be provided, which is placed over the outside of the guide rail 30 to cover the guide rail 30 and serve a decorative purpose.
[0064] Please see Figure 4 and Figure 7 In one embodiment, the guide rail 30 is provided with a groove 34, and a limiting part 341 is provided on the inner wall of the groove 34. A sealing strip 38 is also provided inside the groove 34, and the sealing strip 38 is provided with an anti-detachment part 381 for limiting and cooperating with the limiting part 341. In this way, after the sealing strip 38 is installed inside the groove 34, it can be stably set inside the groove 34 because the anti-detachment part 381 and the limiting part 341 limit and cooperate, and will not easily detach from the groove 34.
[0065] To facilitate the smooth insertion and removal of the molding die 60 from the slide groove 34, the insertion and removal directions of the molding die 60 are as follows: Figure 7 As shown in f, the molding die 60 needs to be provided with a clearance part 61 that avoids the limiting part 341. After being inserted into the slide groove 34, the clearance part 61 will not interfere with the limiting part 341, so it can also be pulled out of the slide groove 34 in the opposite direction, which facilitates the demolding action.
[0066] Furthermore, since the area between the limiting part 341 and the bottom wall of the slide 34 does not directly contact the molding die 60 and is spaced from the clearance part 61, the area between the limiting part 341 and the bottom wall of the slide 34 will not be supported by the molding die 60 and will be deformed or even damaged during the injection molding process.
[0067] Please see Figure 4 and Figure 7 In one embodiment, the guide rail 30 has a reinforcing portion 39 corresponding to the limiting portion 341 on its side 311 facing the corner window glass 10. Thus, by adding the reinforcing portion 39 to the side 311 of the guide rail 30 facing the corner window glass 10, the structural strength of the area between the limiting portion 341 and the bottom wall of the groove 34 can be increased. Simultaneously, the distance between the limiting portion 341 and the inner surface of the corner window glass 10 can be reduced, thereby reducing the pressure borne by the area between the limiting portion 341 and the bottom wall of the groove 34 during injection molding. This improves the deformation and damage defects caused by stress on the area between the limiting portion 341 and the bottom wall of the groove 34 during injection molding.
[0068] Please see Figure 7 In one embodiment, the area between the limiting part 341 and the bottom wall of the slide groove 34 corresponds to the position of the reinforcing part 39. The bottom wall of the slide groove 34 is the wall surface of the slide groove 34 opposite to the groove opening. Thus, the outer contour size of the reinforcing part 39 does not need to be too large, as long as it can cover the area between the limiting part 341 and the bottom wall of the slide groove 34, the structural strength of the area between the limiting part 341 and the bottom wall of the slide groove 34 can be effectively increased.
[0069] Specifically, the area between the limiting part 341 and the bottom wall of the slide 34, that is, the side wall of the slide 34, is the area on the inner wall of the first track plate 31 opposite to the position of the avoidance part 61.
[0070] It should be noted that "positional correspondence" means that, along the direction perpendicular to the side wall of the slide groove 34, the projection of the reinforcing part 39 onto the side wall surface of the slide groove 34 at least partially or completely overlaps with the area between the limiting part 341 and the bottom wall of the slide groove 34.
[0071] Please see Figure 3 In one embodiment, the flush corner window assembly further includes a lift-up glass 50 and a movable bracket 70 connected to the lift-up glass 50. The guide rail 30 is provided with a groove 34, and a sealing strip 38 is provided in the groove 34. The movable bracket 70 is slidably disposed in the sealing strip 38.
[0072] Please see Figure 3 In one embodiment, the outer surface of the lift glass 50 is flush with the outer surface of the corner window glass 10.
[0073] It should be noted that the outer surface of the lift-up window 50 refers to the side of the lift-up window 50 facing outwards from the vehicle, while the inner surface of the lift-up window 50 refers to the side of the lift-up window 50 facing inwards from the vehicle.
[0074] Please see Figure 3 and Figure 7 In one embodiment, a method for processing a flush-mounted corner window assembly according to any of the above embodiments includes the following steps:
[0075] A molding mold 60 is provided, the corner window glass 10 and the guide rail 30 are placed into the molding mold 60, and the mold closing action is performed, so that the inner surface of the corner window glass 10 and the guide rail 30 form a gap area 40, and the gap area 40 is sealed by the molding mold 60 to form an injection cavity.
[0076] Fluid-form edge-wrapping material 20 is injected into the injection cavity from the first injection port 301 and the second injection ports corresponding to the two second gate positions, respectively.
[0077] After the 20mm edge-wrapping material has solidified and formed, the mold opening process is carried out.
[0078] In the above-described processing method for the flush-type corner window assembly, during the manufacturing process, the edging material 20 can be injected into various positions of the gap area 40 between the guide rail 30 and the inner surface of the corner window glass 10 through the first injection port 301 and the two second injection ports. This ensures that each position of the gap area 40 is filled with the edging material 20, thus avoiding defects such as material shortage and retention caused by the edging material not flowing from the area between the transverse section 22 and the inner surface of the corner window glass 10 and filling the gap area 40 between the guide rail 30 and the inner surface of the corner window glass 10 when the distance between them is too small. This improves the connection stability between the guide rail 30 and the inner surface of the corner window glass 10.
[0079] Please see Figure 3 and Figure 7 In one embodiment, the mold closing action includes the steps of:
[0080] The molding die 60 is provided with a first molding surface 62 and a second molding surface 63, and the guide rail 30 is provided with a first wall surface 36 and a second wall surface 37 on opposite sides along its length direction L.
[0081] The first molding surface 62 presses tightly against the first wall surface 36 and seals one side of the interval region 40 along the length direction L, and the second molding surface 63 presses tightly against the second wall surface 37 and seals the other side of the interval region 40 along the length direction L.
[0082] Please see Figures 1 to 4 In one embodiment, a vehicle includes the flush-mounted corner window assembly of any of the above embodiments, and also includes a vehicle body, wherein the flush-mounted corner window assembly is disposed on the vehicle body.
[0083] The aforementioned vehicle, because the edging 20 includes a main body segment 21 integrally injection-molded on the inner surface of the corner window glass 10 and the spacer area 40 between the guide rail 30, and two transverse segments 22 integrally injection-molded on the corner window glass 10 and respectively connected to the opposite ends of the main body segment 21, can achieve the integration of the corner window glass 10, the edging 20, and the guide rail 30 into a single structure. Furthermore, the edging 20 does not protrude from the outer surface of the corner window glass 10, ensuring that the outer surface of the corner window glass 10 is flush with the outer surface of the lift window 50, thus enhancing the product's appearance. In addition, because the guide rail 30 has a first injection port 301, and the two transverse segments 22 each correspond to a portion of the molding die 60... The position is provided with a second injection port. During the manufacturing process, the edge-wrapping material 20 can be injected into various positions of the gap area 40 between the guide rail 30 and the inner surface of the corner window glass 10 through the first injection port 301 and the two second injection ports respectively. This ensures that each position of the gap area 40 is filled with edge-wrapping material 20. In other words, it can avoid defects such as material shortage and retention caused by the difficulty of the edge-wrapping material flowing from the area between the transverse section 22 and the inner surface of the corner window glass 10 and filling the area between the main body section 21 and the inner surface of the corner window glass 10 when the gap between the guide rail 30 and the inner surface of the corner window glass 10 is too small. This can improve the connection stability between the guide rail 30 and the inner surface of the corner window glass 10.
[0084] It should be noted that in this embodiment, "aligned" means that the two surfaces are on the same plane when they meet.
