Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a hidden external watertight sealing strip assembly. Background Art

[0002] Conventional door outer water-cut sealing strips are installed on the door sheet metal and matched with the cover plate, which play the role of sealing, dustproof, waterproof, soundproof, etc. During the glass lifting process, it can also remove dust, water drops and other stains that affect the sight on the glass surface. At the same time, the installation of outer water-cut bright strips can also meet the requirements of aesthetics. However, the appearance of the outer water-cut bright strip is easy to be scratched, and the gap between the sheet metal and the cover plate is easy to be uneven, which affects the OEM's recognition of the appearance of the vehicle.

[0003] The hidden external water cut is installed on the inner side of the outer panel reinforcement. Since the hidden external water cut is completely hidden inside the door sheet metal, there is no external water cut at the waistline of the vehicle, and the door outer panel sheet metal is directly covered, and the appearance is not exposed, which enhances the exquisiteness of the appearance of the vehicle. There is no need to assemble bright strips, which also reduces the production cost. On the basis of retaining the existing functions of the external water cut, it solves the problems of appearance, scratches, uneven matching gaps with sheet metal and cover plates caused by rust stains on the external water cut bright strips, and at the same time improves the overall appearance of the car.

[0004] Related prior art such as the Chinese patent application “Hidden external water cut, hidden external water cut assembly structure and vehicle”, publication number: CN220199034U, discloses: an external water cut body, the external water cut body having a sealing strip and a frame embedded in the sealing strip; the upper end of the external water cut body has a U-shaped clamping portion bent toward the door outer panel, and the upper end of the frame has a U-shaped supporting portion extending into the U-shaped clamping portion; the lower end of the sealing strip has a Y-direction clamping rib on the side facing the door outer panel, and the side of the sealing strip facing the glass is provided with an upper sealing lip and a lower sealing lip, both of which interfere with the glass; a first shielding lip extending upward is provided on the U-shaped clamping portion, the first shielding lip is exposed at the joint between the door outer panel and the glass, and the outer surface of the shielding lip is smoothly connected with the outer surface of the door outer panel.

[0005] However, the angle between the sheet metal and the glass directly affects the installation of the outer watertight seal strip, and unstable installation can easily cause the outer watertight seal strip to fall off, making subsequent repairs and replacements difficult, resulting in increased repair costs. At present, the outer watertight structure affects the overall appearance of the car. The hidden outer watertight eliminates the cost of the outer watertight bright strip, but whether the performance between the outer watertight installation structure and the glass can meet the requirements is a technical problem that needs to be solved.
