[0044] In the width direction of the vehicle, the substrate 1 is located inside the corner window glass 3 and is connected to the corner window glass 3 by injection molding to form a corner window edge assembly 4. That is, the substrate 1 and the corner window glass 3 are first connected to form a corner window edge assembly 4, and then used to connect with the guide rail 2. The whole formed by connecting the corner window edge assembly 4 and the guide rail 2 is the rear door corner window assembly.

[0045] The guide rail 2 and the corner window glass 3 are sequentially arranged from the front to the rear of the vehicle. Along the width direction of the vehicle, the guide rail 2 includes a first guide rail portion 24 and a second guide rail portion 25 located inside the first guide rail portion 24, a first connecting portion is arranged on the second guide rail portion 25, a second connecting portion is arranged at a position corresponding to the first connecting portion on the substrate 1, the guide rail 2 is connected to the substrate 1 through the cooperation of the first connecting portion and the second connecting portion, a side of the first guide rail portion 24 close to the corner window glass 3 is in contact with the corner window glass 3, and the outer wall surface of the first guide rail portion 24 is flush with the outer surface of the corner window glass 3.

[0046] When implementing it, refer to Figure 1 The x direction shown is the direction from the front to the rear of the vehicle, which can be specifically Figure 1 Described in the direction of the drawing shown, the guide rail 2 is located on the left side of the corner window edging assembly 4 and is used to connect with the rear door assembly 5 of the vehicle, and specifically can be connected with the sheet metal of the rear door assembly 5 of the vehicle.

[0047] In this embodiment, the guide rail 2 is connected to the corner window edging assembly 4 as follows: a first connecting portion is provided on the second guide rail portion 25 of the guide rail 2, and a second connecting portion is provided at a position corresponding to the first connecting portion on the substrate 1 of the corner window edging assembly 4, and the first connecting portion and the second connecting portion cooperate to fix the guide rail 2 on the substrate 1. Since the corner window glass 3 and the guide rail 2 are arranged in sequence from the front to the rear of the vehicle, and the corner window glass 3 and the substrate 1 are arranged in sequence along the width direction of the vehicle and the corner window glass 3 is located on the outside of the substrate 1, the second guide rail portion 25 is located on the inside of the first guide rail portion 24, so that the corner window glass 3 and the guide rail 2 can be relatively fixed by connecting the substrate 1 to the guide rail 2, while the outer wall surfaces of the corner window glass 3 and the guide rail 2 can be flush, thereby achieving zero order difference, thereby improving the assembly effect of the entire vehicle, and making the appearance of the entire vehicle better.

[0048] Exemplarily, the first connection portion may be a first connection hole, the second connection portion may be a second connection hole, and the guide rail 2 may be connected to the base plate 1 by inserting a fastener 16 in the first connection hole and the second connection hole. Specifically, the first connection portion and the second connection portion may be threaded holes, and the fastener 16 may be, for example, a bolt or a screw. Alternatively, the first connection portion and the second connection portion may be light holes, and the fastener 16 may be, for example, a fastening pin.

[0049] Exemplarily, the guide rail 2 may be an extruded aluminum guide rail.

[0050] In addition, the substrate 1 may be an injection-molded substrate, and the injection-molded substrate and the corner window glass 3 may be connected as one body by injection molding.

[0051] In summary, compared with the related art in which the corner window glass 3 and the guide rail 2 are snapped or plugged together through grooves, which causes the outer wall surfaces of the corner window glass 3 and the guide rail 2 to be unable to be flush, this embodiment arranges a rear door corner window assembly including a substrate 1, a guide rail 2 and a corner window glass 3, and injection molds the corner window glass 3 and the substrate 1 as one piece, and then connects the guide rail 2 and the substrate 1 together through the cooperation of the first connecting part and the second connecting part. At this time, the outer wall surfaces of the corner window glass 3 and the guide rail 2 can be flush, thereby achieving zero order difference, thereby improving the assembly effect of the entire vehicle and making the appearance of the entire vehicle better.

[0052] Reference Figures 2 to 5As shown, in some embodiments, the substrate 1 includes at least a first substrate 13 and a second substrate 12, and the first substrate 13 and the second substrate 12 are sequentially arranged along the circumference of the corner window glass 3 and are both injection-molded and connected to the corner window glass 3 as a whole, thereby forming a corner window edging assembly 4.

[0053] The first substrate 13 is located between the second substrate 12 and the guide rail 2 , and the second connecting portion is disposed on the first substrate 13 for connecting with the guide rail 2 .

[0054] Further, refer to Figure 4 As shown, the second substrate 12 includes a first sub-substrate 121, a second sub-substrate 122 and a third sub-substrate 123 which are connected in sequence, the first sub-substrate 121 and the third sub-substrate 123 are arranged opposite to each other, and the second sub-substrate 122 is arranged opposite to the first substrate 13; at least one of the first sub-substrate 121 and the third sub-substrate 123 is connected to the rear door assembly 5, thereby realizing a reliable connection between the corner window edging assembly 4 and the rear door assembly 5.

[0055] When implementing it, refer to Figure 4 As shown, the connection structure between the first sub-base 121 and the rear door assembly 5 is as follows: a first fastening nut 14 is provided on the first sub-base 121, a first fastening hole is provided on the rear door assembly 5 at a position corresponding to the first fastening nut 14, and the first sub-base 121 is connected to the rear door assembly 5 via a first fastening connector penetrating through the first fastening hole and the first fastening nut 14. In addition, the first fastening nut 14 can play a Y-direction limiting role when the rear door corner window assembly is assembled on the rear door, and the Y direction here can be understood as the width direction of the vehicle.

[0056] Exemplarily, the first fastening nut 14 may be pre-buried in the first sub-baseboard 121 during the injection molding of the first sub-baseboard 121 , so as to simplify the connection structure between the two and improve the structural strength of the first sub-baseboard 121 .

[0057] Exemplarily, the first fastening member may be a bolt or a screw.

[0058] When implementing it, refer to Figure 4 As shown, the connection structure between the third sub-base 123 and the rear door assembly 5 is as follows: a second fastening nut 15 is provided on the third sub-base 123, a second fastening hole is provided on the rear door assembly 5 at a position corresponding to the second fastening nut 15, and the third sub-base 123 is connected to the rear door assembly 5 via a second fastening connector penetrating the second fastening hole and the second fastening nut 15. In addition, the second fastening nut 15 can play a Y-direction limiting role when the rear door corner window assembly is assembled on the rear door, and the Y direction here can be understood as the width direction of the vehicle.

[0059] Exemplarily, the second fastening nut 15 may be pre-embedded in the third sub-baseboard 123 during the injection molding of the third sub-baseboard 123 , so as to simplify the connection structure between the two and improve the structural strength of the third sub-baseboard 123 .

[0060] Exemplarily, the second fastening member may be a bolt or a screw.

[0061] Reference Figure 4 As shown, in some embodiments, a pre-hanging structure 17 that cooperates with the rear door assembly 5 is provided on the second sub-base 122, so that when the rear door corner window assembly is installed on the vehicle, it can be first connected to the rear door assembly 5 through the pre-hanging structure 17, so as to realize the pre-connection of the rear door corner window assembly and the rear door assembly 5, and then it is convenient to connect and assemble the rear door corner window assembly with the rear door assembly 5 through the fastening holes on different base plates 1, so as to improve the assembly efficiency. In addition, the provision of the pre-hanging structure 17 can play a Y-direction limiting role when the rear door corner window assembly is assembled on the rear door, and the Y direction here can be understood as the width direction of the vehicle.

[0062] For example, refer to Figure 4 As shown, the pre-hanging structure 17 can be a metal nail column embedded or pre-buried in the second sub-baseboard 122, or can also be a metal hook.

[0063] Reference Figure 4 As shown, in some embodiments, the third sub-baseboard 123 is located below the first sub-baseboard 121 , and the third sub-baseboard 123 is provided with an assembly groove 18 for snap-fitting with an external assembly tool.

[0064] During the assembly process of the rear door corner window assembly in the rear door assembly 5, in order to facilitate the operator to quickly install the rear door corner window assembly in place, an assembly tool can be clamped in the assembly groove 18, thereby pushing the rear door corner window assembly upward to achieve assembly in place. This structural design can make the assembly of the rear door corner window assembly more convenient and labor-saving.

[0065] For example, the assembly groove 18 can be provided in a plurality, and the plurality of assembly grooves 18 can be arranged along the Figure 4 As shown, they are arranged at intervals along the direction from the front to the rear of the vehicle.

[0066] In specific implementation, the first substrate 13, the first sub-substrate 121, the second sub-substrate 122 and the third sub-substrate 123 can be formed by PBT (polybutylene terephthalate) + GF30 (embedded bolts) injection molding. The use of a segmented substrate 1 is more conducive to the molding of the substrate, reducing local deformation, and is conducive to the control of the installation point accuracy. It is also conducive to the control of the process and reduces the production cost. The first substrate and the second substrate 12 are positioned in the mold and connected to the corner window glass 3 by edge injection molding (using TPE material, Thermoplastic Elastomer).

[0067] Reference Figure 7 and Figure 8 As shown, in some embodiments, a first seal 6 is provided between the guide rail 2 and the rear door assembly 5. By providing the first seal 6, the windproof sealing between the guide rail 2 and the rear door assembly 5 can be improved to avoid air leakage.

[0068] Exemplarily, the first sealing member 6 may be sealing foam.

[0069] Furthermore, a second sealing member 7 may be provided between the guide rail 2 and the substrate 1 . The second sealing member 7 may improve the assembly sealing performance between the guide rail 2 and the substrate 1 .

[0070] Exemplarily, the second sealing member 7 may be sealing foam.

[0071] Specifically, refer to Figure 8 As shown, there may be six second sealing members 7 , which may specifically include a first sealing foam 71 , a second sealing foam 72 , a third sealing foam 73 , a fourth sealing foam 74 , a fifth sealing foam 75 and a sixth sealing foam 76 .

[0072] Reference Figures 1 to 6 As shown, in some embodiments, a connecting nut 111 is pre-embedded on the substrate 1, and the inner hole of the connecting nut 111 forms a second connecting hole.

[0073] That is to say, when the substrate 1 is formed by injection molding, the connecting nut 111 can be pre-buried or embedded in advance, and then the substrate 1 with the connecting nut 111 can be formed when the substrate 1 is formed by injection molding, so that the connection of the substrate 1 with the pre-connecting nut 111 is simpler and the overall structural strength of the substrate 1 can be improved.

[0074] In some embodiments, reference Figure 6 As shown, there are at least two first connection holes, which are spaced apart along the extension direction of the guide rail 2 (which can be understood as the height direction of the vehicle); there are at least two second connection holes, which correspond one-to-one to the first connection holes.

[0075] That is to say, by providing at least two first connection holes and second connection holes, the connection strength or connection reliability between the guide rail 2 and the substrate 1 can be further improved.

[0076] For example, refer to Figure 4 and Figure 6 As shown, there may be three first connection holes, three fasteners 16, and three connection nuts 111. Figure 6 As shown, a first connection hole is located near the top of the guide rail 2, a first connection hole is located near the bottom of the guide rail 2, and a first connection hole is located in the middle of the guide rail 2 along the height direction, so that the connection between the guide rail 2 and the substrate 1 can be more stable.

[0077] Alternatively, in other implementations, four or more first connection holes and connection nuts 111 may be provided. The specific number of first connection holes and connection nuts 111 may be set according to actual needs, and this is not limited in this embodiment.

[0078] Reference Figure 6 As shown, in some embodiments, a mounting bracket 21 is provided at at least one of the two opposite ends of the guide rail 2 in the height direction of the rear door assembly 5 , and the mounting bracket 21 is used to be connected to the rear door assembly 5 .

[0079] In specific implementation, only the upper end of the guide rail 2 may be provided with a mounting bracket 21 , which is connected to the rear door assembly 5 via the mounting bracket 21 , and a rivet nut 23 may be directly provided at the bottom end of the guide rail 2 to be screwed to the rear door assembly 5 .

[0080] The connection structure between the mounting bracket 21 and the guide rail 2 is specifically as follows: a first mounting hole is provided on the mounting bracket 21, and a second mounting hole is provided on the guide rail 2 at a position corresponding to the first mounting hole. The mounting bracket 21 is connected to the guide rail 2 by a mounting member 22 penetrated through the first mounting hole and the second mounting hole. The mounting bracket 21 serves to connect the rear door assembly 5, and can serve as a limit in the Y direction and the X direction when the guide rail 2 and the rear door assembly 5 are assembled. Here, the Y direction can be understood as the width direction of the vehicle, and the X direction can be understood as the length direction of the vehicle (i.e., the direction from the front of the vehicle to the rear of the vehicle).

[0081] In a specific implementation, the mounting member 22 may be a blind rivet, which is arranged in the first mounting hole and the second mounting hole to achieve riveting, thereby reliably connecting the mounting bracket 21 to the guide rail 2.

[0082] Alternatively, in some other implementations, the mounting member 22 may also be a screw or a bolt.
