As shown in Figures 1 and 2, the improved structure of the outer water-cut end cap is installed on the end of the outer water-cut body 100, wherein the outer water-cut body 100 includes a bright strip 300 and a body 200 formed by double pressing, and the body 200 is in an inverted U shape, including an aluminum frame 201, a PP material body 202 and a TPV material body 203. Here, the PP material body 202 is polypropylene, and the TPV material body 203 is thermoplastic vulcanized rubber. The TPV material body 203 forms a lip that matches the glass, and the PP material body 202 is coated on both sides of the aluminum frame 201. On the side, a barb 204 is provided at the end of the aluminum frame 201 inside the U-shaped groove 205 of the main body 200. Here, the aluminum frame 201 is used to increase the rigidity of the main body 200 and to facilitate the limiting of the end cover 400. As an optimization, in order to increase the space in the U-shaped groove 205, it is necessary to adopt a variable cross-section technology for the two inner lips 206 in the U-shaped groove 205, so that the inner lips 206 disappear at the end, and a limiting groove 207 is formed at the end of the external water-cut main body 100 through a punching process, which is mainly used for limiting the end cover 400.

As shown in Figures 3, 4 and 5, the end cover 400 mainly includes an end cover body 401, a cover 402, a connector 403 and a cantilever body 404, the cover 402 is located at the end of the end cover body 401 and is used for shielding, the connector 403 is located at the upper side edge of the end cover body 401, wherein the connector 403 is formed on the cover 402 and is used to be connected with the outer water cut body 100, the cantilever body 404 is located in the middle position of the end cover body 401, and a hook body 405 is integrally formed on the cantilever body 404, and the hook body 405 has a guide inclined surface 405 1. By using the inclined surface guiding action, the hook body 405 can be smoothly clamped into the door sheet metal hole 501 along the direction of the inclined surface, wherein the cantilever body 404 has a deformation space, and the deformation space of the cantilever body 404 is used to insert the end cover body 401 into the outer water-cut body 100 and make the hook body 405 fixedly connected to the door sheet metal 500. In this way, the connector 403 can be connected with the limiting groove 207 to form the end cover 400 and the body 200 as one piece, and then connected to the door sheet metal 500 through the hook body 405, so that the end cover 400, the body 200 and the door sheet metal 500 are connected. 00 are connected into one piece, which is firm and reliable. The whole process is convenient and fast, and no additional process is required to achieve fixation. As a further optimization, a limiting protrusion 406 for clamping with the outer water-cutting body 100 is integrally formed on the cantilever body 404, wherein the limiting protrusion 406 is provided with a contact inclined surface 4061, and the contact inclined surface 4061 is limited between the end cover 400 and the outer water-cutting body 100, so that the end cover 400 can be prevented from being pulled out of the body 200. In order to facilitate the rapid assembly of the end cover 400 onto the body 200, the end cover body 401 is close to the side of the body 200. A guide bevel 407 is provided, and a limiting groove 207 is provided on the main body 200. When the end cover 400 is assembled on the outer water-cut main body 100, the connector 403 and the limiting protrusion 406 are clamped in the limiting groove 207, which is more secure and reliable and will not fall off; as a further optimization, as shown in Figure 3, a step surface 4021 is formed at the end of the cover 402, wherein the step surface 4021 is for better assembling the bright strip 300, and a limiting block 408 is provided on the back of the cover 402 and the connector 403, so that the end cover 400 can be better fixed to the main body 200.

As shown in Figures 6 and 7, when assembling the entire outer water cut, first assemble the end cover 400 into the main body 200, and engage it with the limiting groove 207 through the connecting body 403 and the limiting protrusion 406, and then assemble the bright strip 300 onto the main body 200. Finally, when the outer water cut main body 100 is pressed toward the door sheet metal hole 501, the guide bevel 4051 on the hook body 405 first contacts the door sheet metal side wall 502, and using the guiding effect of the guide bevel 4051, the hook body 405 can be smoothly engaged in the door sheet metal hole 501 along the direction of the bevel.

After the hook body 405 is inserted into the door sheet metal hole 501, the contact surface 503 on the hook body 405 will come into contact with the surface of the door sheet metal hole 501, and then the door sheet metal hole 501 will play a limiting and self-locking role on the hook body 405 through the contact surface 503, making it difficult for the hook body 405 to be pulled out of the door sheet metal hole 501.

The specific embodiments described herein are merely examples of the spirit of the present invention.
