These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figures 1-3 As shown, the car door window frame structure of this utility model embodiment includes: an upper window frame 1, a B-pillar outer panel 2, a C-pillar outer panel 3, a window sill reinforcing plate 4, and two upper window frame reinforcing plates 5.

[0029] The upper end of the outer panel 2 of the B-pillar is connected to the front end of the upper window frame 1. Specifically, the outer panel 2 of the B-pillar and the upper window frame 1 are connected by carbon dioxide gas shielded welding, and the connection between the outer panel 2 of the B-pillar and the upper window frame 1 forms the first corner.

[0030] The upper end of the C-pillar outer panel 3 is connected to the rear end of the upper window frame 1. Specifically, the C-pillar outer panel 3 and the upper window frame 1 are connected by carbon dioxide gas shielded welding, and the connection between the C-pillar outer panel 3 and the upper window frame 1 forms a second corner.

[0031] The front end of the window sill reinforcement plate 4 is connected to the outer panel 2 of the B-pillar, the lower end of the outer panel 2 of the B-pillar extends out from the window sill reinforcement plate 4, and the rear end of the window sill reinforcement plate 4 is connected to the lower end of the outer panel 3 of the C-pillar. Specifically, the window sill reinforcement plate 4 is installed using carbon dioxide gas shielded welding.

[0032] Two reinforcing plates 5 are installed at the first and second corners respectively, and each reinforcing plate 5 has decorative panel mounting holes 51. Specifically, the reinforcing plates 5 are installed using carbon dioxide gas shielded welding. The decorative panel mounting holes 51 are used to install decorative panels, and the holes can be configured according to the size of the decorative panel and the fixing clips to make the installation of the decorative panel more secure.

[0033] Based on the above structural configuration, by connecting the upper end of the B-pillar outer panel 2 to the front end of the upper window frame 1, the connection between the B-pillar outer panel 2 and the upper window frame 1 forms a first corner. By connecting the upper end of the C-pillar outer panel 3 to the rear end of the upper window frame 1, the connection between the C-pillar outer panel 3 and the upper window frame 1 forms a second corner. By installing the two window frame upper reinforcing plates 5 correspondingly at the first and second corners, it is beneficial to improve the structural strength at the corners. Furthermore, the window frame upper reinforcing plate 5 has decorative panel mounting holes 51, which is beneficial for the installation of decorative panels.

[0034] like Figure 2 As shown, in some embodiments, the upper reinforcing plate 5 of the window frame includes a body 52, a flange 53 disposed on the outer edge of the body 52, and a decorative panel mounting hole 51 disposed on the body 52. ​​The flanges 53 of the two upper reinforcing plates 5 of the window frame are respectively installed at the first corner and the second corner. In this way, it is beneficial to increase the installation area of ​​the upper reinforcing plate 5 of the window frame and improve the stability of the installation.

[0035] like Figure 2 As shown, in some embodiments, the folded edge 53 includes a first folded edge 53a and a second folded edge 53b. The first folded edge 53a of the first window frame reinforcing plate 5 is welded to the front end of the upper window frame 1, the second folded edge 53b of the first window frame reinforcing plate 5 is welded to the outer panel 2 of the B-pillar, the first folded edge 53a of the second window frame reinforcing plate 5 is welded to the rear end of the upper window frame 1, and the second folded edge 53b of the second window frame reinforcing plate is welded to the outer panel 3 of the C-pillar. Thus, by providing the first folded edge 53a and the second folded edge 53b, they can be installed on different structures respectively, thus maintaining ease of installation.

[0036] like Figure 3 As shown, in some embodiments, the mounting hole 51 includes a first mounting hole 51a and a second mounting hole 51b, with the first mounting hole 51a located near the first folded edge 53a and the second mounting hole 51b located near the second folded edge 53b. Thus, by providing the first mounting hole 51a and the second mounting hole 51b, the stability of the trim panel installation is improved.

[0037] like Figure 2As shown, in some embodiments, the reinforcing plate 5 on the window frame has a positioning hole 54, which is located between the first mounting hole 51a and the second mounting hole 51b. Specifically, the decorative panel has a protrusion that fits into the positioning hole 54, thereby facilitating the positioning and installation of the decorative panel.

[0038] In some embodiments, the angle between the first folded edge 53a and the second folded edge 53b and the body 52 is both α, which satisfies 85°≤α≤95°.

[0039] like Figure 1 As shown, in some embodiments, an inner B-pillar panel 6 is included, connected to the inner side of the outer B-pillar panel 2. Thus, the inner B-pillar panel 6 can strengthen the structure of the outer B-pillar panel 2.

[0040] like Figure 1 As shown, in some embodiments, an inner C-pillar panel 7 is included, connected to the inner side of the outer C-pillar panel 3. Thus, the inner C-pillar panel 7 can strengthen the structure of the outer C-pillar panel 3.

[0041] like Figure 1 As shown, in some embodiments, a guide rail bracket 8 is included, which is installed at the lower end of the outer panel 2 of the B-pillar. The guide rail bracket 8 ensures the stability and smoothness of the door window lifting process.

[0042] like Figure 1 As shown, in some embodiments, a rear reinforcing plate 9 for the window frame is included, which is connected to the lower end of the outer panel 3 of the C-pillar and the rear end of the reinforcing plate 4 of the window sill. In this way, the rear reinforcing plate 9 for the window frame can strengthen the connection between the outer panel 3 of the C-pillar and the reinforcing plate 4 of the window sill.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
