[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to a Chinese patent application filed with the China Patent Office on December 6, 2023, with application number 2023116622583 and titled “Vehicle, flush door corner window assembly and processing method thereof”, and the entire contents of the patent application are incorporated into this disclosure by reference. Technical Field

[0003] The present application relates to the technical field of glass edging, and in particular to a vehicle, a flush door corner window assembly and a processing method thereof. Background Art

[0004] With the development of glass edging technology, the corner window glass and the lifting glass in the related technology are usually set to be flush, that is, the outer surface of the corner window glass and the outer surface of the lifting glass are on the same plane. Among them, the lifting glass is slidably set in the sliding groove of the guide rail, and the guide rail is integrally injection-molded with the corner window glass through the edging. The edging is wrapped around the edge of the corner window glass, or connected between the guide rail and the corner window glass. When the edging is wrapped around the edge of the corner window glass, it will cause the edging to protrude from the outer surface of the corner window glass and not be flush with the outer surface of the corner window glass, so this structural method is gradually being eliminated. When the edging is integrally injection-molded and connected between the guide rail and the corner window glass, the edging can be set on the inner surface of the corner window glass, so that the outer surface of the corner window glass and the outer surface of the lifting glass are designed to be flush.

[0005] However, after the edging is integrally injection-molded and connected between the guide rail and the corner window glass, the two opposite surfaces of the edging are respectively connected and fixed to the corner window glass and the guide rail. The resulting flush door corner window assembly product has poor stability and is prone to loosening or even detachment after a period of use or under the action of external force.

[0040] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0041] As described in the background technology, the flush door corner window assembly products obtained in the related technology have poor stability, and are prone to loosening or even detachment defects after being used for a period of time or under the action of external force. The inventors have found that the reason for this problem is that in the injection molding process in the related technology, the edging material is generally injected into the cavity formed by the corner window glass and the mold from the gate positions designed for the upper and lower horizontal sections of the edging. However, the design space between the guide rail and the corner window glass and the mud groove is relatively limited, so that the distance between the guide rail and the inner surface of the corner window glass is relatively small, resulting in a relatively thin edging. Especially when the corner window glass is large in the vertical direction and the guide rail is long, the guide rail and the inner surface of the corner window glass are prone to injection molding material shortages, stagnation and other problems. As a result, the flush door corner window assembly products finally obtained have poor stability, and are prone to loosening or even detachment defects after being used for a period of time or under the action of external force.

[0042] Based on the above reasons, the present application provides a vehicle, a flush door corner window assembly and a processing method thereof, which can improve the technical solution for the connection stability performance between the guide rail and the corner window glass.

[0043] Referring to Figures 1 to 4 , Figure 1 shows a structural diagram of the assembled corner window glass 10 with the edging 20. Figure 2 shows a structural diagram of the assembled lift glass 50, guide rail 30, and corner window glass 10, with the lift glass 50 shown in Figure 2 being a partial structure. Figure 3 shows a cross-sectional view taken along line AA in Figure 2 , and Figure 4 shows a structural diagram of the guide rail 30. One embodiment of the present application provides a flush door corner window assembly comprising the corner window glass 10, the edging 20, and the guide rail 30. The guide rail 30 is spaced relative to the inner surface of the corner window glass 10 and is provided with a first injection port 301. The edging 20 includes a main section 21 integrally injection-molded in the spacing area 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 section 21. The main section 21 is provided with a first gate corresponding to the position of the first injection port 301, and the two transverse sections 22 are each provided with a second gate.

[0044] 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 interior of the vehicle, and the outer surface of the corner window glass 10 refers to the side of the corner window glass 10 facing the exterior of the vehicle.

[0045] The above-mentioned flush door corner window assembly, because the edge 20 includes a main section 21 that is integrally injection-molded in the spacing area 40 between the inner surface of the corner window glass 10 and the guide rail 30, and two transverse sections 22 that are integrally injection-molded on the corner window glass 10 and respectively connected to the opposite ends of the main section 21, the corner window glass 10, the edge 20 and the guide rail 30 can form an integral structure, and the edge 20 does not protrude from the outer surface of the corner window glass 10, so that the outer surface of the corner window glass 10 and the outer surface of the lifting glass 50 can be arranged flush with each other, thereby enhancing the appearance of the product; in addition, because the first injection port 301 is provided on the guide rail 30, the two transverse sections 22 each correspond to the molding mold 6 0 is provided with a second injection port, and during the manufacturing process, the edging 20 material can be injected into various positions of the spacing 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, so that various positions of the spacing area 40 can be filled with the edging 20 material, that is, it can avoid defects such as material shortage and retention caused by the edging 20 material being difficult to flow from the area between the transverse section 22 and the inner surface of the corner window glass 10 and fill the area between the main section 21 and the inner surface of the corner window glass 10 due to the small distance between the guide rail 30 and the inner surface of the corner window glass 10, thereby improving the connection stability between the guide rail 30 and the inner surface of the corner window glass 10.

[0046] In some embodiments, the first injection port 301 includes but is not limited to a non-enclosed opening provided on the guide rail 30, and may also be provided as a closed opening, or may be provided in other forms, and may be flexibly adjusted and provided according to actual needs. Among them, a non-enclosed opening refers to selecting one point of the mouth wall of the injection port as the starting point, and moving from the starting point along the mouth wall in a single direction cannot return to the starting point; conversely, a closed hole refers to selecting one point of the mouth wall of the injection port as the starting point, and moving from the starting point along the mouth wall in a single direction can return to the starting point. In addition, the second injection port is provided on the molding die 60, and specifically, for example, it is the discharge port of the injection tube of the molding die 60, or for example, it is the discharge port of the injection channel 64 of the molding die 60, or it may be provided in other forms. The shape of the second injection port is similar to that of the first injection port 301, and will not be repeated here.

[0047] Optionally, the first injection port 301 and the second injection port are independently configured to have various regular shapes, including but not limited to U-shaped ports, semicircular ports, circular ports, semi-elliptical ports, elliptical ports, polygonal ports, and other irregular shapes, which can be flexibly adjusted and configured according to actual needs. In this embodiment, the first injection port 301 is specifically configured as a U-shaped port, as shown in FIG4 .

[0048] In some embodiments, after the edging material 20 is injected into the spacing region 40 through the first injection port 301, the edging material 20 also fills the first injection port 301 and is integrally injection molded therein. In the molded product, a filling portion 211 can be observed at the first injection port 301. A gate residue, i.e., a first gate, is formed on the surface 2111 of the filling portion 211 at the first injection port 301 at a location in contact with the injection channel 64. Similarly, a gate residue, i.e., a second gate, can be observed at a location on the transverse section 22 corresponding to the second injection port.

[0049] In some embodiments, the edging 20 includes but is not limited to at least one of plastic materials such as PP (Poly propylene), ABS (Acrylonitrile Butadiene Styrene plastic), PC (Poly carbonate), PA (Poly amide), SAN (acrylonitrile-styrene copolymer), PBT (Poly butylene terephthalate), POM (Polyformaldehyde), PVC (Poly vinyl chloride), and PU (Poly urethane).

[0050] Referring to Figures 1 to 4 , in one embodiment, the first injection port 301 is located in the middle of the guide rail 30 along its length L. The first gate is correspondingly located in the middle of the guide rail 30 along its length L. Specifically, the first gate is located in the exact middle of the guide rail 30 along its length L, as shown, for example, at point P1 in Figure 1 . This allows the fluid edging material 20 to flow along opposite ends of the guide rail 30 after injection through the first gate, improving its uniformity and ensuring that the gap 40 between the guide rail 30 and the inner surface of the corner window glass 10 is completely filled. Furthermore, the second gate can be located anywhere along the transverse section 22. Specifically, the positions of the two second gates on the two transverse sections 22 are respectively shown as point P2 in Figure 1. After the fluid edging material 20 is injected from the second injection port corresponding to the second gate position, a part of the edging material 20 will include but is not limited to being attached to the inner surface and / or outer surface of the corner window glass 10, and the other part can flow and fill the spacing area 40 between the guide rail 30 and the inner surface of the corner window glass 10.

[0051] Please refer to Figures 4 and 5. Figure 5 shows a structural schematic diagram of the injection molding process in which the edging 20 material is injected into the spacing area 40 through the first injection port 301 via the injection channel 64. The injection channel 64 is arranged in the molding mold 60, and the other structures of the molding mold 60 are hidden and not displayed. In some embodiments, the guide rail 30 includes a first track plate 31 interconnected with the main body section 21. The first injection port 301 is formed on the first track plate 31, and the main body section 21 is provided with a filling portion 211 filled in the first injection port 301. The 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 311 of the first track plate 31 facing away from the main body section 21.

[0052] Please refer to Figures 4 and 6. Figure 6 shows a schematic diagram of the structure in which the edging 20 material is injected into the spacing area 40 through the first injection port 301 via the injection channel 64 during the injection molding process. In other embodiments, the surface 2111 of the filling portion 211 and the side surface 311 of the first track plate 31 facing away from the main 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 surface 311 of the first track plate 31 facing away from the main 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 surface 311 of the first track plate 31 facing away from the main section 21. Optionally, the height difference S between the surface 2111 of the filling portion 211 and the side surface 311 of the first track plate 31 facing away from the main section 21 includes but is not limited to 1mm-10mm, specifically 1mm, 3mm, 5mm or 10mm, so that the protruding height of the surface 2111 of the filling portion 211 at the first injection port 301 is reduced, which is used to absorb the edging material 20 remaining at the first gate of the surface 2111 of the filling portion 211, thereby reducing or even avoiding the noise caused by the movement of the movable bracket 70 in the slide groove 34 during the movement of the lifting glass 50.

[0053] 3 and 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 slide groove 34.

[0054] Referring to Figures 3 and 4 , in one embodiment, the guide rail 30 is provided with at least one abutment portion 35 . The abutment portion 35 tightly abuts the inner surface of the corner glass 10 . This close contact between the abutment portion 35 and the inner surface of the corner glass 10 provides precise positioning, ensuring a predetermined spacing between the guide rail 30 and the inner surface of the corner glass 10. This allows precise control of the thickness of the main body section 21 . Furthermore, the mold 60 maintains tight contact with the inner surface of the corner glass 10 and the guide rail 30, thereby reducing adhesive overflow and flash defects.

[0055] In some embodiments, the abutting portion 35 includes but is not limited to various protruding structures such as a convex point, a boss, a convex hump, or a convex column.

[0056] In some embodiments, for example, only one abutting portion 35 is provided, and the inner surface of the corner window glass 10 is tightly abutted against each other by only one abutting portion 35 .

[0057] In other embodiments, the abutment portion 35 is not limited to being provided as a single one, and can be provided as a plurality of abutment portions 35 spaced apart on the guide rail 30. The abutment portions 35 are sequentially spaced apart along the longitudinal direction L of the guide rail 30, thereby ensuring that the distance between various portions of the guide rail 30 and the inner surface of the corner window glass 10 is consistent, thereby maintaining a high consistency in thickness at various locations along the longitudinal direction L of the edge 20.

[0058] In some other embodiments, there may be two abutting portions 35 , which are respectively located on two opposite sides of the first injection port 301 .

[0059] Referring to FIG. 4 , in some embodiments, the abutting portion 35 is specifically disposed on a side surface 311 of the first rail plate 31 facing the corner window glass 10 .

[0060] It should be noted that the "abutment portion 35" can be "a part of the guide rail 30", that is, the "abutment portion 35" and the "other parts of the guide rail 30" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the guide rail 30", that is, the "abutment portion 35" can be manufactured independently and then combined with the "other parts of the guide rail 30" into a whole.

[0061] Please refer to Figure 4. In some embodiments, the abutment portion 35 can include at least one first abutment portion 35135, which directly abuts against the inner surface of the corner window glass 10, for example, so as to achieve precise positioning of the guide rail 30; or it can 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, for example, so that the slider of the forming mold 60 is in close abutment against the inner surface of the corner window glass 10, so as to achieve precise positioning of the guide rail 30.

[0062] Referring to Figures 3, 7, and 8, Figure 8 illustrates the structure of the mold 60 in close contact with the first wall 36 and the second wall 37 during the injection molding process according to one embodiment of the present application. In some embodiments, the guide rail 30 is provided with a first wall 36 along one side of its lengthwise direction L, and the main body section 21 is provided with a first side surface 212 along one side of its lengthwise direction L. The first wall 36 and the first side surface 212 are flush with each other. Thus, during the injection molding process, the first pressing surface 62 of the mold 60 is tightly pressed against the first wall 36, simultaneously sealing one side of the spacer region 40. As a result, after the main body section 21 is injection molded, the first side surface 212 is flush with the first wall 36, preventing material overflow and flash defects in the main body section 21. Furthermore, since the main body section 21 is not exposed beyond the first wall 36, the volume of the cavity is relatively reduced, making it more susceptible to material shortages and retention defects. Glue filling through the first injection port 301 can significantly alleviate these defects. In addition, there is no need to set up an interior panel to cover the edging 20, that is, the interior panel in the related art can be omitted, and the guide rail 30 can be directly exposed inside the car as a decorative surface. Since there is no need to set up an interior panel, the structure is simplified and the cost is reduced.

[0063] Referring to Figures 3, 7, and 8, in some embodiments, the guide rail 30 has a second wall 37 along the other side of its length L, and the main body section 21 has a second side 213 along the other side of its length L. The second wall 37 is flush with the second side 213. This function is similar to the flush function of the first wall 36 and the first side 212, and will not be further described.

[0064] Referring to Figures 3, 7, and 8, in one embodiment, the first wall 36 is positioned adjacent to the notch of the chute 34, while the second wall 37 faces away from the notch. No injection ports are provided on the second side surface 213 or the second wall 37, thereby preventing the gate on the edging 20 from being exposed and affecting the appearance. Furthermore, when the second side surface 213 and the second wall 37 are aligned, the visible area of ​​the corner window glass 10 is increased.

[0065] In some embodiments, an interior panel may also be provided, and the interior panel cover may be provided on the outside of the guide rail 30 so as to shield the guide rail 30 and serve a decorative purpose.

[0066] Referring to Figures 4 and 7 , in one embodiment, the guide rail 30 is provided with a chute 34, the inner wall of which is provided with a stopper 341. A sealing strip 38 is also provided within the chute 34, and the sealing strip 38 is provided with an anti-slip portion 381 for engaging with the stopper 341. Thus, after the sealing strip 38 is installed within the chute 34, the anti-slip portion 381 engages with the stopper 341, thereby maintaining its position and preventing it from being easily removed from the chute 34.

[0067] In order to facilitate the smooth insertion of the forming mold 60 into the slide groove 34 and the smooth withdrawal from the slide groove 34, the insertion and withdrawal directions of the forming mold 60 are shown as f in Figure 7. A avoidance portion 61 that avoids the limit portion 341 needs to be provided on the forming mold 60. After being inserted into the slide groove 34, the avoidance portion 61 will not interfere with the limit portion 341, so that it can also be withdrawn from the slide groove 34 in the reverse direction, thereby facilitating the demoulding action.

[0068] In addition, since the area between the limiting portion 341 and the bottom wall of the slide groove 34 is not in direct contact with the molding mold 60, and is spaced apart from the avoidance portion 61, the area between the limiting portion 341 and the bottom wall of the slide groove 34 is not supported by the molding mold 60 and may be deformed or even damaged during the injection molding process.

[0069] Referring to Figures 4 and 7 , in one embodiment, a reinforcing portion 39 is provided on the side 311 of the guide rail 30 facing the corner glass 10, corresponding to the stopper 341. The addition of the reinforcing portion 39 to the side 311 of the guide rail 30 facing the corner glass 10 enhances the structural strength of the region between the stopper 341 and the bottom wall of the runner 34. This also reduces the distance from the inner surface of the corner glass 10, thereby reducing the pressure exerted on the region between the stopper 341 and the bottom wall of the runner 34 during the injection molding process. This, in turn, mitigates deformation and damage caused by the forces exerted on the region between the stopper 341 and the bottom wall of the runner 34 during the injection molding process.

[0070] Referring to Figure 7 , in one embodiment, the area between the stopper 341 and the bottom wall of the chute 34 corresponds to the location of the reinforcement 39. The bottom wall of the chute 34 is also the wall of the chute 34 opposite the notch. As such, the reinforcement 39 does not need to be excessively large; it only needs to cover the area between the stopper 341 and the bottom wall of the chute 34, effectively increasing the structural strength of the area between the stopper 341 and the bottom wall of the chute 34.

[0071] The area between the limiting portion 341 and the bottom wall of the sliding groove 34 is also the side wall of the sliding groove 34 , specifically the area on the inner wall of the first track plate 31 opposite to the avoiding portion 61 .

[0072] It should be noted that position correspondence means that, along the side wall direction perpendicular to the slide groove 34 , the projection of the reinforcement portion 39 on the side wall surface of the slide groove 34 at least partially or completely overlaps with the area between the limiting portion 341 and the bottom wall of the slide groove 34 .

[0073] Referring to Figure 3 , in one embodiment, the flush door quarter window assembly further includes a lift glass 50 and a movable bracket 70 connected to the lift glass 50. The guide rail 30 defines a slide groove 34, within which a sealing strip 38 is disposed. The movable bracket 70 is slidably disposed.
