Description

Technical Field

[0001] This utility model relates to the field of automotive sealing accessories technology, and in particular to an automotive corner window sealing assembly. Background Technology

[0002] With the development of automotive sealing technology, the role of internal and external water-resistant sealing strips in vehicle door systems is becoming increasingly important. They not only affect the overall airtightness and waterproof performance of the vehicle, but also directly relate to the vehicle's appearance quality and user experience. Especially in the corner window area, due to the complex structure, limited space, and multiple component junctions, higher requirements are placed on the adaptability, sealing reliability, and assembly precision of the sealing strips.

[0003] The existing water-cutting seal strip structure and its matching relationship with surrounding parts are usually as follows: the water-cutting seal strip inside the corner window and the corner joint are fixedly installed on the inner panel of the vehicle body, while the water-cutting seal strip outside the corner window is fixed to the body sheet metal. However, the water-cutting seal strip outside the corner window is usually an exposed structure, which to some extent obscures the exposed area of ​​the triangular glass. This not only affects the aesthetics but also disrupts the overall visual harmony. In addition, this exposed design also makes it impossible for the triangular glass to maintain a good external connection and match with the body sheet metal, resulting in poor sealing performance and easy wind noise and rainwater leakage problems, which further affect the driving experience and the overall quality of the vehicle.

[0004] Therefore, there is an urgent need for a car corner window sealing assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sealing component for automotive corner windows that can effectively improve aesthetics and visual harmony, enhance water tightness, and reduce wind resistance.

The inner water-cutting sealing strip 4 is fixedly installed on the inner body panel 5 and forms a sealing contact with the inner surface of the triangular window glass 3. This configuration, with the outer water-cutting sealing strip 1 using a hidden structure design, eliminates visual obstruction, allowing for a smooth transition between the outer body panel 2 and the triangular window glass 3. This differs from traditional exposed water-cutting strips that obstruct the glass area, improving aesthetics and visual harmony, optimizing aerodynamic performance, reducing wind noise and wind resistance. Simultaneously, the outer water-cutting sealing strip 1 and the inner water-cutting sealing strip 4 provide dual sealing protection, improving waterproof performance and reliability, and enhancing watertightness.

The insert is snapped to the inner edge of the vehicle body outer panel 2 through a snap-fit ​​structure 6. The contact part has an elastic sealing lip and forms an interference fit with the surface of the triangular window glass 3. The transition part connects the insert and the contact part, and the outer contour surface of the transition part is flush with the outer surface of the vehicle body outer panel 2.

[0035] Optionally, the automotive corner window sealing assembly also includes a B-pillar corner joint 7, which is fixedly connected to the outer body panel 2.

[0036] Optionally, the outer water-cutting sealing strip 1, the inner water-cutting sealing strip 4, and the B-pillar corner 7 are integrally formed. This configuration results in better structural stability for the integrally formed outer water-cutting sealing strip 1, inner water-cutting sealing strip 4, and B-pillar corner 7, reduces the number of additional parts, lowers assembly complexity, and effectively improves production efficiency.

[0037] Optionally, the automotive corner window sealing assembly also includes a first connecting plate 8 and a second connecting plate 9, which are embedded in the B-pillar corner 7 and fixedly installed on the outer body panel 2. Furthermore, to improve assembly precision and compatibility, and to achieve lightweighting and cost optimization, both the first connecting plate 8 and the second connecting plate 9 are made of plastic.

[0038] Optionally, the automotive corner window sealing assembly also includes a first frame 11, a second frame 12, and a claw structure 10. The claw structure 10 protrudes from the first frame 11 and is snapped onto the inner body panel 5. The inner water-cutting sealing strip 4 is fixedly connected to the first frame 11. The buckle structure 6 protrudes from the second frame 12 and is snapped onto the outer body panel 2. The outer water-cutting sealing strip 1 is fixedly connected to the second frame 12.
