[0044] The main body mounting portion 41 is provided with a first lip edge 43 protruding outward, and the top mounting portion 42 is provided with a second lip edge 44 protruding downward.

[0045] A glass guide rail 5 is connected to one side of the lifting glass 3 , and a limiting buffer portion 6 for limiting the position of the glass guide rail 5 is installed at one end of the top frame edge 22 .

[0046] When the top of the glass guide rail 5 cooperates with the limiting buffer 6, the top edge of the lifting glass 3 is in the glass guide groove 4, the first lip 43 presses against the inner surface of the lifting glass 3, the second lip 44 presses against the upper edge of the lifting glass 3, and the step difference of the outer surface of the joint between the lifting glass 3 and the top frame edge 22 is less than 5 mm.

[0047] The vehicle door window frame structure provided by the present invention is integrally mounted on a vehicle door sheet metal 1. The vehicle door window frame structure comprises a vehicle door window frame 2, a lifting glass 3, a glass guide groove 4, a glass guide rail 5 and a limit buffer portion 6.

[0048] The door window frame 2 includes two side frame edges 21 and a top frame edge 22. The lower end of the side frame edge 21 is connected to the door sheet metal 1, and the top frame edge 22 is connected between the top ends of the two side frame edges 21. The lifting glass 3 is assembled in the door window frame 2, and is slidably connected to the side frame edge 21, and can be moved downward to the glass storage groove of the door sheet metal 1 to realize the lowering and raising functions of the lifting glass 3. Regarding the assembly relationship between the lifting glass 3 and the side frame edge 21 and the door sheet metal 1, reference can be made to the contents in the prior art, and no further description will be given here.

[0049] A frame edge groove 222 is provided on the top frame edge 22 , and the lower part and the outer side of the frame edge groove 222 have openings.

[0050] The glass run channel 4 is a rubber member, and is installed in the frame edge groove 222. The glass run channel 4 is generally L-shaped, and includes a vertically extending main body assembly portion 41 and a laterally extending top assembly portion 42. The top assembly portion 42 is integrally connected to the top of the main body assembly portion 41.

[0051] The main body assembly part 41 is connected to the inner groove wall of the frame edge groove 222, and the top assembly part 42 extends outward from the top of the frame edge groove 222. The outer edge of the top assembly part 42 is slightly inside the outer surface 221 of the top frame edge 22 or the two are flush.

[0052] At least one first lip edge 43 is provided on the main body assembly portion 41 . The first lip edge 43 protrudes from the inside to the outside and is used for pressing the inner surface of the lifting glass 3 .

[0054] The glass guide rail 5 is connected to the side of the lifting glass 3 facing a side frame edge 21. The glass guide rail 5 can be bonded to the lifting glass 3 by glue. A limit buffer 6 is installed at the bottom of the top frame edge 22, which is located above the glass guide rail 5 and is used to limit the glass guide rail 5. When the top of the glass guide rail 5 cooperates with the limit buffer 6, the limit buffer 6 provides a limit for the upward movement of the glass guide rail 5, and can also provide a limit for the left and right direction of the glass guide rail 5 (the inside and outside direction of the door window frame 2).

[0055] When the lifting glass 3 rises to the position, the top of the glass guide rail 5 cooperates with the limit buffer 6, and the top edge of the lifting glass 3 is in the glass guide groove 4. At this time, the first lip 43 presses against the inner surface of the lifting glass 3, which helps to limit the inward movement of the lifting glass 3, and the second lip 44 presses on the upper edge of the lifting glass 3, which helps to limit the upward movement of the lifting glass 3 and also helps to reduce the noise caused by collision when the lifting glass 3 rises to the position. The step difference at the junction of the outer surface 31 of the lifting glass 3 and the outer surface 221 of the top frame edge 22 is less than 5mm. That is, the outer surface 31 of the top area of ​​the lifting glass 3 is slightly inside the outer surface 221 of the top frame edge 22, and the step difference between the two is less than 5mm, and even the outer surface 31 of the top area of ​​the lifting glass 3 is flush with the outer surface 221 of the top frame edge 22.

[0056] Therefore, the vehicle door window frame structure provided by the present invention provides a limiting and guiding function for the lifting glass 3 through the cooperation of the limiting buffer portion 6 and the glass guide rail 5, and the glass guide groove 4 no longer bears the outer limiting function of the lifting glass 3, so the glass guide groove 4 is set to be L-shaped, and the outer surface of the lifting glass 3 is no longer confined in the glass guide groove 4. When the top edge of the lifting glass 3 is in the glass guide groove 4, the step difference of the outer surface of the joint between the lifting glass 3 and the top frame edge 22 is less than 5mm, and can even reach a flush state, which is beneficial to reducing wind noise, and is also beneficial to maintaining the continuity of the appearance shape and improving the appearance quality.

[0057] In one embodiment, if Figure 4 As shown, when the top edge of the lifting glass 3 is in the glass guide groove 4, the outer surface of the joint between the lifting glass 3 and the top frame edge 22 is flush, which further reduces wind noise, maintains the continuity of the appearance, and improves the appearance quality.

[0058] In one embodiment, if Figure 5-9 As shown, the limiting buffer portion 6 includes a connecting plate 61 connected to the top frame edge 22 and a limiting block 62 connected below the connecting plate 61 .

[0065] When the lifting glass 3 is about to be lifted into place, the guide rail boss 51 is inserted into the guide groove 63 from bottom to top, and the guide groove 63 provides guidance for the movement of the guide rail boss 51 and can provide position limiting for the inner and outer directions of the lifting glass 3.

[0066] When the liftable glass 3 is lifted to its proper position, the guide rail ridge 52 abuts against the buffer body 64 , providing a limit for the upward movement of the liftable glass 3 and having a buffering effect.

[0067] In one embodiment, if Figure 6 and Figure 8 As shown, the guide groove 63 is configured to be wider at the bottom and narrower at the top. Correspondingly, the guide rail boss 51 is also configured to be wider at the bottom and narrower at the top, so that the guide rail boss 51 can enter the guide groove 63 from bottom to top. The guide groove 63 provides guidance for the upward movement of the guide rail boss 51 to guide and correct the position of the lifting glass 3.

[0068] In one embodiment, if Figure 5-6 and Fig. 9 As shown, two buffer bodies 64 are arranged at intervals at the bottom of the limit block 62 , and two guide rail ridges 52 are correspondingly arranged at the top of the glass guide rail 5 .

[0069] When the liftable glass 3 is lifted to its position, the two guide rail ridges 52 respectively support the two buffer bodies 64 to provide better limiting and buffering effects for the upward movement of the liftable glass 3 .
