Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a windshield trim assembly. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] With the continuous development of society and economy, consumers are increasingly demanding higher requirements for vehicle sealing performance. In particular, during the rainy season, preventing rainwater leakage, reducing wind noise, and improving the quietness of the vehicle interior have become key concerns. Among these, waterproof and windproof decorative strips can effectively improve the above problems, thereby enhancing driving comfort and safety.

[0004] Windshield trim strips are located on both sides of the car's windshield. Their main function is to seal the gap between the glass and the car body sheet metal, preventing rainwater from seeping in and cold air from entering the car. Traditionally, windshield trim strips require the application of sealant and waiting for the sealant to dry completely before installation.

[0005] However, the aforementioned technologies have the following drawbacks. Since the sealing adhesive needs to be completely dry before the windshield trim strip can be installed, the installation cycle for the OEM is relatively long. In addition, as an injection-molded part, the windshield trim strip is subject to injection stress deformation, which makes it difficult for the deformed trim strip to effectively adhere to the sealing adhesive, resulting in gaps and increased wind noise. Furthermore, the sealing adhesive is prone to cracking and seepage under external rainwater penetration and sun exposure, leading to rain leakage and wind intrusion. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a windshield trim assembly that can improve the sealing effect of the windshield trim.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A windshield trim assembly includes a first injection-molded strip and a second injection-molded strip. A connector is fixedly disposed on the first injection-molded strip.
