[0038] A water retaining strip positioning structure disclosed in the present invention can provide an end mounting point for a vehicle door exterior waterproof assembly, thereby facilitating the installation and positioning of the vehicle door exterior waterproof assembly on the vehicle door.

[0039] In the present invention, the water retaining strip positioning structure mainly includes an installation joint 1, which is an injection molded joint. When used later, it is connected to the two ends of the outer barrier sealing strip 4, and is clamped with the vehicle door and limited to each other, thereby ensuring the stability and accuracy of the installation of the outer door waterproof assembly on the vehicle door.

[0040] In addition, the mounting joint 1 described in the present invention includes a positioning insert 2; the positioning insert 2 is mainly a connecting piece, which not only facilitates the installation of the mounting joint 1 in the outer sealing strip 4, but also facilitates the subsequent use, when the end area of ​​the vehicle door outer waterproof assembly is clamped and installed on the upper sheet metal of the vehicle door outer panel 5.

[0041] In the present invention, the positioning insert 2 described in the present invention includes a secondary positioning rib 21 and a main positioning rib 22; the secondary positioning rib 21 and the main positioning rib 22 are interconnected at one end close to the roof, and are spaced apart at the end away from the roof; an assembly gap is formed between the secondary positioning rib 21 and the main positioning rib 22; based on the above design, the vertical cross-section of the positioning insert 2 disclosed in the present invention is an inverted V-shaped or inverted U-shaped structure, and such a setting makes it convenient for the secondary positioning rib 21 and the main positioning rib 22 to be clamped on the clamping flange 52 on the door outer panel 5 during subsequent use.

[0042] In addition, in the present invention, the secondary positioning ribs 21 and the main positioning ribs 22 are arranged to intersect each other. Such an arrangement facilitates the structure in which the secondary positioning ribs 21 and the main positioning ribs 22 are connected at one end and freely extend at the other end.

[0043] Furthermore, the main positioning rib 22 described in the present invention includes a main rib plate 221, which is a part of the main positioning rib 22. A clamping mechanism is provided on the main rib plate 221 described in the present invention; the setting of the clamping mechanism is mainly to facilitate the subsequent installation and use, and to clamp with the clamping groove 53 on the clamping flange 52, so as to realize the installation and fixation of the installation joint 1 on the vehicle door outer panel 5; at the same time, it can also realize the Z-direction limitation of the installation joint 1, and finally realize the Z-direction limitation of the vehicle door outer waterproof assembly.

[0044] In the present invention, the clamping mechanism includes an avoidance groove 227 arranged on the main rib plate 221; a first protruding clamping rib 225 is arranged in the avoidance groove 227, and the avoidance groove 227 is equivalent to a through groove opened on the main rib plate 221, and the first protruding clamping rib 225 is equivalent to one end connected to the inner wall of the avoidance groove 227 and the other end extending freely, and a first clamping rib flange 226 is provided on the first protruding clamping rib 225; the first clamping rib flange 226 is arranged on the side of the first protruding clamping rib 225 close to the secondary positioning rib 21, and the first clamping rib flange 226 can be selectively arranged perpendicular to the first protruding clamping rib 225; such a setting enables the first clamping rib flange 226 and the first protruding clamping rib 225 to form a hook-type structure, which is essentially a buckle structure, which is convenient for subsequent hanging in the clamping groove 53 on the clamping flange 52.

[0045] Furthermore, in the present invention, a limiting rib 224 is also provided on the main rib 221; the limiting rib 224 is located on the side of the main rib 221 away from the secondary positioning rib 21; the limiting rib 224 is arranged at one end of the main rib 221 close to the main positioning rib 22 and the secondary positioning rib 21; the limiting rib 224 mainly plays a limiting role, and subsequently presses against the end of the outer barrier sealing strip 4, playing a good positioning and limiting role, avoiding the positioning inlay from rotating around the outer barrier sealing strip 4, affecting the stability of the installation joint 1 embedded in the outer barrier sealing strip 4.
