Description

External water-cut sealing strip, vehicle door and vehicle

Technical Field

The present application relates to the technical field of sealing strips, and in particular to vehicle door sealing strips.

Background Art

As a common exterior decoration part of automobiles, the outer water cut is installed between the window glass and the door outer panel. It is used to cut off water droplets, water mist and dust on the surface of the window glass during the process of raising and lowering the window glass, and it also plays a role in aesthetics. Conventional outer water cuts are installed on the door window sill, resulting in the main part of the outer water cut being exposed, which is prone to cracking and damage under the aging effect of wind and sun; and the outer surface of the outer water cut is usually connected with a bright strip, which increases the cost of the sealing strip, but the bright strip will affect the exquisite appearance of the whole vehicle after rusting.

In addition, due to the certain tolerance of the sheet metal of the front and rear doors of the car, the window sills of the front and rear doors always have a certain height difference. At this time, after the external water cuts are installed, consumers can easily see that the two external water cuts are not on the same horizontal plane, affecting the overall beauty of the door and even the entire car.

The hidden external water cut can hide the body inside the door sheet metal, and the hidden external water cut has less exposed part above the window sill, which helps to improve the aesthetics and quality of the door. Chinese utility model patent CN217532525U discloses a hidden external water cut door and a vehicle, wherein the hidden external water cut door includes a door outer panel, a reinforcing plate, a support, an external water cut assembly and glass, the upper end of the door outer panel is an inwardly folded edge, and a reinforcing plate is provided on the inner side of the door outer panel, one end of the reinforcing plate is fixedly mounted on the lower end of the door outer panel, and the other end is fixedly mounted in the edge, one end of the support is fixedly mounted on the inner side of the reinforcing plate, the external water cut assembly is fixedly mounted on the end of the support away from the reinforcing plate, and in the vertical direction, the upper end of the external water cut assembly is located on the inner side of the upper end of the door outer panel, and the glass is movably mounted on the inner side of the door outer panel, and the glass is abutted against the side of the external water cut assembly away from the door outer panel. The defects of this design include: 1. The hidden outer water cut is fixed by relying on the elastic parts and the supporting parts. As the rubber parts age, the fixing effect of the outer water cut will be affected, and abnormal noise will be easily generated when the glass is raised or lowered; 2. The outer water cut body must be provided with a metal frame, which increases the production cost and weight of the outer water cut, and is not conducive to the lightweight development of the car; 3. A long section of the second lip of the application will always be exposed to the air, affecting the appearance of the car door.

DETAILED DESCRIPTION

In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the present application is not limited to the specific embodiments of the following disclosure.

In this application, the external water-cut sealing strip may also be abbreviated as "sealing strip" or "external water-cut".

It is particularly important to note that in FIG1 and FIG2 , due to the derived viewing angle, the deformed first lip 103 ′ appears to be placed on the second lip 107 . In fact, referring to FIG3 , the deformed first lip is always below the second lip 107 .

In the present application, the wear-resistant layer may be flocked or pasted, or may be a wear-resistant material produced by any formula and any process combination disclosed in Chinese patent application CN117186524A.

An external water-cut sealing strip comprises a first lip and a second lip, wherein the second lip abuts against an external sheet metal and is opposite to the first lip; one side of the first lip abuts against a door glass and deforms to move closer to the second lip, thereby forming a closed space in cooperation with the second lip.

The buckle can be detachably penetrated through the outer water-cut sealing strip, and the outer water-cut sealing strip is installed on the inner sheet metal of the vehicle door, and the inner sheet metal is inserted into the inverted U-shaped structure of the outer sheet metal. When the OEM installs the outer water-cut sealing strip, it only needs to align the buckle of the outer water-cut sealing strip with the hole on the inner sheet metal and then insert it, which is simpler and more convenient to install than the traditional outer water-cut sealing strip. When the outer water-cut sealing strip needs to be replaced, the outer water-cut sealing strip can be easily replaced by removing or pulling out the buckle.

A wear-resistant layer is provided on the side of the first lip edge that abuts against the window glass to prevent the first lip edge from being worn out by the window glass during the lifting process. When the window glass is raised, the first lip edge is deformed (see the deformed first lip edge 103' in the figure) and approaches the second lip edge, forming a closed space in cooperation with the second lip edge. It should be noted that the undeformed first lip edge will also cooperate with the outer sheet metal and the second lip edge to form a relatively closed space (a certain gap is formed in the drawings of this application for illustration purposes) to prevent external dust and rain from entering the door.

A wear-resistant layer is provided on the second lip edge. This is because the deformed first lip edge 103' will continue to deform toward the lower left after contacting the second lip edge, that is, the first lip edge will continue to deform and extend into the closed space, so that the deformed first lip edge 103' and the second lip edge have relative contact friction, which will cause the lip edge to be damaged over time. By providing a wear-resistant layer, the service life of the sealing strip can be increased.

We can clearly see from the figure that the second lip is offset from the outer sheet metal of the door and is not higher than the height of the outer sheet metal of the door. The advantage of this design is that, on the one hand, less of the sealing strip is exposed to the air, thereby extending the service life of the second lip, reducing appearance quality problems, and improving the quality of the entire vehicle; on the other hand, when consumers observe the front and rear door window frames from the outside, they will only see that the sheet metal is almost on the same level (visually, the height of the sheet metal does not differ much), but they cannot see the external water-cut sealing strip, thus avoiding the defect of the external water-cut sealing strip on the traditional front and rear door window frames that is easily misaligned horizontally (that is, the external water-cut sealing strip is difficult to align on the horizontal line due to manufacturing reasons).

Furthermore, the outer water-cut sealing strip of the present application is provided with a third lip edge which abuts against the inner sheet metal, and cooperates with the second lip edge to make the outer water-cut sealing strip more stably installed on the inner sheet metal, thereby avoiding abnormal noise of the sealing strip caused by the tiny gap between the buckle and the inner sheet metal.

Furthermore, the outer water-cut sealing strip of the present application is provided with a fourth lip edge, and a wear-resistant layer is provided on the side of the fourth lip edge close to the glass. When the car door is closed, it is easy to cause the window glass to shake laterally, and the fourth lip edge can collide with it to prevent the window glass from laterally hitting the door sheet metal. The design of the fourth lip edge can also enhance the dust and water resistance of the outer water-cut sealing strip, and prevent dust and rain from entering deeper into the door.

Furthermore, at least one inner reinforcing rib is arranged in the sealing strip body. In the present application, there are two inner reinforcing ribs. Furthermore, at least one outer reinforcing rib is arranged on the outside of the sealing strip body. In the present application, there are two outer reinforcing ribs. In addition to improving the overall strength of the sealing strip, the design of the inner and outer reinforcing ribs also has the following functions: when the outer water-cut sealing strip is produced, the puncher can directly punch holes at a certain interval between the two inner reinforcing ribs, and the operator can easily insert the buckle into the hole in the post-processing process. The function of the inner reinforcing rib can also be to form a certain limit to prevent the tail end of the buckle from shaking up and down, thereby improving the installation firmness of the outer water-cut sealing strip. The outer reinforcing rib is offset against the inner sheet metal, so that the sealing strip body is not directly attached to the inner sheet metal, which brings the following functions: avoiding contamination of the sheet metal; avoiding the heat from the sheet metal to the sealing strip in a large area under high temperature in summer, causing the sealing strip to accelerate thermal aging; avoiding the sealing strip from sticking to the door sheet metal under long-term use, which causes inconvenience in replacing the sealing strip. Furthermore, the coordinated design of internal and external reinforcement ribs allows polypropylene (PP) material to replace the metal frame material of traditional sealing strips, reducing the weight of the sealing strip while also giving the sealing strip better mechanical strength.

Furthermore, the two ends of the outer water-cut sealing strip are provided with cover plates (not shown in the figure), and foam is provided inside the outer water-cut sealing strip. When the first lip edge abuts against the window glass, it will also be squeezed with the foam to reduce the noise of the glass rising and falling. It should be noted that the length of the foam is much shorter than the length of the outer water-cut sealing strip.

A vehicle door, wherein any of the above-mentioned outer water-cut sealing strips is detachably mounted on the inner sheet metal of the vehicle door by means of buckles.

A car is provided with any one of the above-mentioned external water-cut sealing strips.

A car is provided with the above-mentioned car door.
