The first protrusion 361 and the second protrusion 371 are arranged opposite each other along the length of the guide rail 30.
[0063] like Figure 3As shown, the edging 20 is installed inside the guide rail 30. Specifically, the side of the edging 20 away from the window glass 10 is installed in the first guide groove 33 of the guide rail 30. The first outer surface 211 of the first segment 21 of the edging 20 is opposite to the wall surface of the first side wall 35 of the guide rail 30, and the protrusion 213 abuts against the wall surface of the first side wall 35. The first injection hole 215 is opposite to and communicates with the mounting hole 352, and the injection pipe 216 passes through the mounting hole 352 to facilitate the injection of colloid into the first injection hole 215. The second outer surface 221 of the second segment 22 is opposite to the wall surface of the second side wall 36 of the guide rail 30, the first slot 223 holds the first protrusion 361, and the first abutting protrusion 224 abuts against a portion of the first side surface 31 of the guide rail 30 in the width direction of the guide rail 30 to restrict the movement of the edging 20 in the width direction of the guide rail 30. The third outer surface 231 of the third segment 23 is disposed opposite to the wall surface of the third side wall 37 of the guide rail 30. The second slot 233 holds the second protrusion 371, and the second abutting protrusion 234 abuts against a portion of the first side surface 31 of the guide rail 30 in the width direction of the guide rail 30 to restrict the movement of the edging 20 in the width direction of the guide rail 30. A second filling space B is provided between the edging 20 and the guide rail 30. The outer surface of the edging 20 and the groove wall of the first guide groove 33 of the guide rail 30 together form the second filling space B. In this embodiment, the second filling space B is connected to the first filling space A through the first injection hole 215 and the connecting hole 214, and the second filling space B is connected to the second guide groove 34 through the mounting hole 352.
[0064] like Figure 3 As shown, the first connecting part 40 is located in the first filling space A and connects to the wall of the mounting groove 24 of the edge protector 20 on one side of the window glass 10. In this embodiment, the first connecting part 40 is a colloid and is formed by an injection molding process, used to bond the edge protector 20 to the edge of the window glass 10. The second connecting part 50 is located in the second filling space B and connects to the wall of the first guide groove 33 of the guide rail 30 on the outer surface of the edge protector. In this embodiment, the second connecting part 50 is a colloid and is formed by an injection molding process, used to bond the guide rail 30 to the edge protector 20. The first segment 21 of the edge protector 20 is provided with a protruding ridge 213. The protruding ridge 213 can increase the contact area between the first outer surface 211 and the second connecting part 50 and increase the roughness of the first outer surface 211, so that the edge protector 20 can be more firmly bonded to the guide rail 30. The first sidewall 35 of the guide rail 30 is provided with a groove 351. The groove 351 can increase the contact area between the wall surface of the first sidewall 35 and the second connecting part 50 and increase the roughness of the wall surface of the first sidewall 35, thereby improving the reliability of the bonding between the guide rail 30 and the edge 20. The first connecting part 40 is located in the first filling space A, and the second connecting part 50 is located in the second filling space B. They are not visible from the outside of the vehicle 1000, so the built-in first connecting part 40 and second connecting part 50 will not affect the aesthetic appearance of the window glass assembly 100.
[0065] In this embodiment, the two ends of the vehicle window glass 10 along its length are respectively fixed to the first limiting groove 254 of the first retaining member 25 and the second limiting groove 264 of the second retaining member 26. The inner wall surfaces of the first limiting groove 254 and the second limiting groove 264 can directly abut against the surface of the vehicle window glass 10, or they can be indirectly bonded through the first connecting part 40. That is, the gap between the inner wall surface of the first limiting groove 254 and the surface of the vehicle window glass 10 is filled by the first connecting part 40, and the gap between the inner wall surface of the second limiting groove 264 and the surface of the vehicle window glass 10 is filled by the first connecting part 40.
[0066] In some embodiments, such as Figure 6 As shown, the window glass assembly 100 also includes a third connecting portion 60. The third connecting portion 60 is disposed within the communicating hole and connects between the first connecting portion 40 and the second connecting portion 50, for bonding and integrating the guide rail 30 and the edge trim 20 to the edge of the window glass 10. In this embodiment, the third connecting portion 60 is an adhesive, and the first connecting portion 40, the second connecting portion 50, and the third connecting portion 60 are integrally formed by an adhesive injection process. The adhesive injection process has lower costs, reducing the manufacturing cost of bonding and integrating the guide rail 30 and the edge trim 20 to the edge of the window glass 10 and thus the overall manufacturing cost of the window glass assembly 100.
[0067] In this embodiment, the guide rail 30 and the edge band 20 are bonded and integrated to the edge of the window glass 10 using the first connecting part 40 and the second connecting part 50, which improves the appearance of the window glass assembly 100. Furthermore, the first connecting part 40 and the second connecting part 50 are made by injection molding, which saves the manufacturing cost of the window glass assembly 100.

The first surface 11 of the window glass 10 is opposite to the first inner surface 212 of the first segment 21, the second surface 12 is opposite to the second inner surface 222 of the second segment 22, and the third surface 13 is opposite to the third inner surface 232 of the third segment 23. The first retaining protrusion 225 abuts against the second surface 12, and the second retaining protrusion 235 abuts against the third surface 13. The oppositely arranged first retaining protrusion 225 and second retaining protrusion 235 retain the window glass 10 in the thickness direction. The two ends of the window glass 10 along the length direction are respectively fixed to the first limiting groove 254 of the first retaining member 25 and the second limiting groove 264 of the second retaining member 26. The window glass 10 is interference-fitted with the first retaining member 25 and the second retaining member 26. The first limiting groove 254 and the second limiting groove 264 can limit the window glass 10 from swaying along the thickness direction of the edge 20 or moving along the length direction of the edge 20 within the mounting groove 24. A first filling space A is provided between the window glass 10 and the edge 20. One end of the window glass 10 and the groove wall of the mounting groove 24 together form the first filling space A.
[0072] Step S3: Install guide rail 30 on the side of the edging 20 away from the window glass 10, forming a second filling space B between the edging 20 and the guide rail 30.
[0073] Specifically, the side of the edging 20 facing away from the window glass 10 is installed in the first guide groove 33 of the guide rail 30. The first outer surface 211 of the first segment 21 of the edging 20 is opposite to the wall surface of the first side wall 35 of the guide rail 30, and the protrusion 213 abuts against the wall surface of the first side wall 35. The first injection hole 215 is opposite to and communicates with the mounting hole 352, and the injection pipe 216 passes through the mounting hole 352 to facilitate the injection of colloid into the first injection hole 215. The second outer surface 221 of the second segment 22 is opposite to the wall surface of the second side wall 36 of the guide rail 30, the first slot 223 holds the first protrusion 361, and the first abutting protrusion 224 abuts against a portion of the first side surface 31 of the guide rail 30 in the width direction of the guide rail 30 to restrict the movement of the edging 20 in the width direction of the guide rail 30. The third outer surface 231 of the third segment 23 is disposed opposite to the wall surface of the third side wall 37 of the guide rail 30. The second slot 233 holds the second protrusion 371, and the second abutting protrusion 234 abuts against a portion of the first side surface 31 of the guide rail 30 in the width direction of the guide rail 30 to restrict the movement of the edging 20 in the width direction of the guide rail 30. A second filling space B is provided between the edging 20 and the guide rail 30. The outer surface of the edging 20 and the groove wall of the first guide groove 33 of the guide rail 30 together form the second filling space B. In this embodiment, the second filling space B is connected to the first filling space A through the first injection hole 215 and the connecting hole 214, and the second filling space B is connected to the second guide groove 34 through the mounting hole 352.
[0074] Step S4: Inject colloid into the first filling space A and the second filling space B to form a first connecting part 40 connecting the window glass 10 and the edging 20 and a second connecting part 50 connecting the edging 20 and the guide rail 30.
[0075] In this embodiment, colloid is injected into the first injection hole 215 through the injection pipe 216. The colloid flows into and fills the first filling space A, and then enters the second filling space B through the connecting hole 214, filling the second filling space B as well. After the colloid in the first filling space A cures, it forms a first connecting part 40. The first connecting part 40 connects between one side of the window glass 10 and the groove wall of the mounting groove 24 of the edge protector 20, and is used to bond the edge protector 20 to the edge of the window glass 10. After the colloid in the second filling space B cures, it forms a second connecting part 50. The second connecting part 50 connects between the outer surface of the edge protector and the groove wall of the first guide groove 33 of the guide rail 30, and is used to bond the guide rail 30 to the edge protector 20. The first section 21 of the edge protector 20 is provided with a protruding ridge 213. The protruding ridge 213 can increase the contact area between the first outer surface 211 and the second connecting part 50 and the roughness of the first outer surface 211, so that the edge protector 20 can be more firmly bonded to the guide rail 30. The first sidewall 35 of the guide rail 30 is provided with a groove 351. The groove 351 can increase the contact area between the wall surface of the first sidewall 35 and the second connecting part 50 and the roughness of the wall surface of the first sidewall 35, thereby improving the reliability of the bonding between the guide rail 30 and the edge 20.
[0076] The adhesive placed inside the connecting hole cures to form a third connecting part 60. The third connecting part 60 connects between the first connecting part 40 and the second connecting part 50, and is used to bond and integrate the guide rail 30 and the edge trim 20 to one side of the window glass 10. The first connecting part 40, the second connecting part 50 and the third connecting part 60 are all integrally formed by an injection molding process, which reduces the process cost of bonding and integrating the guide rail 30 and the edge trim 20 to the edge of the window glass 10 and manufacturing the window glass assembly 100.
