Problems solved by technology

[0003] In order to solve the problem that the frame of the door opening sealing strip of the existing vehicle model is easy to open when it is installed in the corner installation area after extrusion molding, and the lip is prone to warping and the clamping is not firm in the corner area, the present invention An automobile door opening sealing strip and its installation method are provided. The skeleton of the door opening sealing strip is optimized, and a pre-tightening process is adopted, so that the U-shaped groove of the door opening sealing strip itself is pre-tightened, which greatly improves the door opening sealing strip. The fastening is firm and solves the problem of protruding lips
The door opening sealing strips of existing models all use two connecting strips, which makes the skeleton of the sealing strip more rigid, so the sealing strip is prone to opening when it is bent

Embodiment 1

[0029] As shown in Fig. 4(a), an automobile door opening sealing strip includes a skeleton and a rubber layer coated outside the skeleton. The skeleton includes multiple ribs and a single connecting strip for connecting multiple ribs. The connection position between the bar and the rib is located at the transverse 1 / 3 position of the rib.

Embodiment 2

[0031] As shown in Figure 4(b), an automobile door opening sealing strip includes a skeleton and a rubber layer coated outside the skeleton. The skeleton includes multiple ribs and a single connecting strip for connecting multiple ribs. The single connection The connecting position of the bar and the rib is located at the 1 / 2 position of the rib transverse direction.

Embodiment 3

[0033] As shown in Figure 4(c), an automobile door opening sealing strip includes a skeleton and a rubber layer coated outside the skeleton. The skeleton includes multiple ribs and a single connecting strip for connecting multiple ribs. The single connection The connection position between the bar and the rib is located at the transverse 2 / 3 position of the rib.

[0034] Such as Figure 5 As shown, a method for installing an automobile door opening seal. After the door opening seal is extruded, the corner installation area of ​​the door opening seal is first pre-tightened, and the pre-tightened door opening seal is then clamped with the side corners. catch.

[0035] Further, the pre-tightening of the corner installation area of ​​the door opening weather strip includes: firstly, the door opening weather strip is clipped and clamped on the clamp, and then the U-shaped groove of the door opening weather strip is shrinked and deformed by extrusion.

[0036] Such as Figure 6 A...

Abstract

The invention discloses an automobile door opening sealing strip, which is characterized in that an automobile door opening sealing strip framework comprises a plurality of ribs and connecting stripsfor connecting the plurality of ribs, and the number of the connecting strips is reduced from two to one. The invention further discloses an installation method of the automobile door opening sealingstrip, after the door opening sealing strip is extruded and formed, a corner installation area of the door opening sealing strip is pre-tightened, and then the pre-tightened door opening sealing stripis connected with a side wall corner in a clamped mode. The framework of the door opening sealing strip is optimized, and the pre-tightening process is adopted, so that a clamping U-shaped groove ofthe door opening sealing strip is pre-tightened, the clamping firmness of the door opening sealing strip is greatly improved, and the problem that the lip edge tilts outwards is solved.

Description

technical field [0001] The invention relates to an automobile door hole sealing strip and an installation method thereof, belonging to the technical field of automobile body installation. Background technique [0002] At present, the extrusion section of the door opening seal strip of existing models is as follows: figure 1 As shown, the skeleton of the door opening sealing strip of the model is as follows image 3 As shown, when the door opening sealing strip of the existing model is installed in the corner area, the worker will bend the door opening sealing strip to an angle similar to the side corner, and at this time the U-shaped groove of the door opening sealing strip will open, as shown figure 2 As shown, the sealing strip of the door opening will not be clamped firmly, and its lip will also be warped outward, leaving the seam with the side wall. Contents of the invention [0003] In order to solve the problem that the frame of the door opening sealing strip of t...
