[0019] In the figure, window frame 100; glass groove 101; matching part 102; step difference part 103; overlapping surface part 104; overlapping gap 105; anti-slip step 106; boss 107; extension step 108; corner 109; outer panel 200; inner panel 300; inner support part 301; protective part 302; automobile glass 400; glass sealing strip 500; outer decorative panel 600; connecting tape 700; distance D from the upper end of the window frame to the outer decorative panel.

[0020] like Figure 1 As shown, the door frame of the present invention for reducing the step-difference structure of the vehicle door glass mainly includes a window frame 100, an outer panel body 200 and an inner panel body 300. The entire window frame 100, the outer panel body 200 and the inner panel body 300 can be formed by roll forming. The lower side of the outer panel body 200 is the inner panel body 300, wherein the right side of the outer panel body 200 and the right side of the inner panel body 300 are covered and connected, so that they can form a whole and enhance the overall strength. The lower side of the inner panel body 300 has an inner support portion 301, and a protective member 302 is installed on the lower bottom surface of the inner support portion 301. Here, the bottom of the inner support portion 301 can be effectively protected by the protective member 302. The inner side surface of the window frame 100 has a glass groove 101, and the glass groove 101 is provided with an automobile glass 400 and a glass sealing strip 500. The glass sealing strip 500 can ensure good sealing performance of the entire automobile glass 400.

[0021] like Figure 2 As shown, the biggest innovation of this patent is that the structure used is to reduce the distance D from the upper end of the window frame to the outer decorative panel. Specifically, the upper end of the window frame 100 is divided from left to right into a matching portion 102, a step difference portion 103 and an overlapping surface portion 104. The size of the step difference portion 103 and the sufficient width of the overlapping surface portion 104 need to be considered when setting. The left end of the outer panel 200 is placed on the overlapping surface portion 104, and a continuous or intermittent welding connection is made at the overlapping surface portion 104 along the length direction of the window frame 100, so that the outer panel 200 and the window frame 100 are combined together. Here, the distance of the step difference portion 103 is staggered, and it can be seen that since the outer panel 200 is directly overlapped, rather than the sheathing connection of the prior art, the distance D from the upper end of the window frame to the outer decorative panel can be significantly reduced, thereby reducing the step difference between the door glass and the window frame 100, improving the aesthetics of the entire vehicle, and reducing the wind resistance of the vehicle movement.

[0022] In order to ensure smooth overlap, as an optimization, an overlap gap 105 is provided between the overlap surface 104 and the step difference portion 103, and an arc welding connection is performed at the overlap gap 105 along the length direction of the window frame 100, so that it can be ensured that the left end portion of the outer panel 200 and the overlap surface 104 have adjustment space, which is convenient for connection. The upper end of the outer panel 200 has an outer decorative panel 600, and the lower side of the outer decorative panel 600 has a connecting tape 700, wherein the matching portion 102 and the left end portion of the outer panel 200 jointly form a mounting surface to provide an installation space for the connecting tape 700 on the outer decorative panel 600, so that it can be ensured that the entire outer decorative panel 600 is attached to the mounting surface, thereby ensuring the aesthetics of the entire vehicle, and in order to ensure the smooth installation of the glass sealing strip 500, the corner 109 of the matching portion 102 An anti-slip step 106 is provided, and a boss 107 is provided on the bottom of the window frame 100. The anti-slip step 106 and the boss 107 limit the position of the glass sealing strip 500 installed in the glass groove 101, so that the two sides of the glass sealing strip 500 are limited to prevent slipping out. The lower side of the outer panel 200 is the inner panel 300, wherein the right side of the outer panel 200 and the right side of the inner panel 300 are covered and connected, and the boss 107 of the window frame 100 is integrally connected downwardly with an extension step 108, and a corner 109 is provided at the extension step 108, and the left end portion of the inner support portion 301 is welded to the corner 109, so that the inner panel 300 and the window frame 100 are firmly combined together, so that the inner panel 300, the window frame 100 and the outer panel 200 form a whole, thereby ensuring the strength of the entire door frame.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
