Specifically, the outer water cut is usually clamped at the stop position of the window sill on the outside of the door sheet metal through its own characteristics.

[0003] When assembling the external water-cut on the door sheet metal, a common installation method is to visually align the water-cut end face with the sheet metal edge to ensure the length direction position after the external water-cut is assembled.

The fourth guide portions 3012 are provided on both sides at the same time, which is conducive to improving the stability of the outer water cutter 1 during assembly. In this embodiment, the fourth guide portion 3012 is specifically a chamfer or fillet provided at the edge of the positioning groove 3011, so as to facilitate the positioning portion 202 to be smoothly embedded in the positioning groove 3011.

[0085] It should be noted here that in order to ensure the reliability of positioning and the strength of the positioning structure, preferably, the depth of the positioning groove 3011 is 3mm-5mm, such as 3mm, 4mm or 5mm, and the width of the positioning groove 3011 is 8mm-12mm, such as 8mm, 9mm, 10mm, 11mm or 12mm.

[0086] After the external water cut 1 is installed on the door sheet metal 3, the gap between the two sides of the positioning part 202 and the door sheet metal 3 is preferably 0.1mm, so as to better limit the position of the external water cut assembly in the length direction of the door. At the same time, the gap between the bottom of the positioning part 202 and the bottom wall of the positioning groove 3011 is preferably 0.5mm, so as to ensure that the external water cut assembly can be snapped into place, to prevent the problem of not being snapped into place and affecting the positioning effect.

[0087] The vehicle of this embodiment uses the aforementioned external water-cut assembly, so the production process is simple, the assembly efficiency of workers can be improved, and the assembly cost can be saved.

[0088] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
