Description

Lower clamping strip of automobile front windshield Technical Field The application relates to the technical field of automobile parts, in particular to a lower clamping strip of automobile front windshield. Background With the development of the automobile industry, the design and installation technology of front windshield is also advancing continuously. The front windshield of a modern car is usually designed with a large curved surface, so that the appearance of the car is improved, and higher requirements on safety and tightness are also put forward. The lower clamping strip of the front windshield is used as an important part for connecting the front windshield and the vehicle body, and the structure and the material selection directly influence the installation effect of the glass and the overall performance of the vehicle. The prior art under-windshield clip strip structure is typically provided with a soft sealing material from a rigid skeletal structure to ensure a good fit with the glass. Related prior art such as chinese patent application "a front windshield card strip system", CN202221297407.1 discloses that this system includes card strip body, card strip body includes bar spare and U type groove, bar spare with U type groove integrated into one piece, the U type groove includes curved arm and the first straight arm and the second straight arm of setting in curved arm both ends, the second straight arm includes the interference protruding hook, the interference protruding hook is provided with the through-hole, protection moulding includes main part and card foot portion. The front windshield glass clamping strip system provided by the application can solve the problem that the clamping strip opening is deformed by external force, realize the sealing performance of the matching of the clamping strip and the air inlet grille, and play roles in noise reduction, water prevention and sealing. Meanwhile, the hollow holes of the clamping strips are made of half soft materials and half hard structures, so that the air inlet grille is assembled with smaller insertion force, the clamping claws of the air inlet grille are prevented from being separated from the clamping strips, the matched stability of the clamping strips and the clamping strips is ensured, and meanwhile, abnormal noise is prevented from being assembled.
