Abstract

The invention relates to the technical field of car weatherstrips and in particular to a car door-frame weatherstrip. The car door-frame weatherstrip comprises a lower rubber sheet, wherein a first sealing assembly and a second sealing assembly are mounted on the lower rubber sheet; the first sealing assembly comprises a first rubber sheet; the first rubber sheet is a triangular hollow tube; a sponge core is arranged in the inner cavity of the first rubber sheet; brackets for supporting the sponge core are integrally formed at the inner wall of the first rubber sheet; the second sealing assembly comprises a second rubber sheet which is provided with a plurality of water dividing grooves at the upper part; the first rubber sheet and the second rubber sheet are connected by an upper connecting part and a lower connecting part; and a cavity is arranged between the upper connecting part and the lower connecting part. The car door-frame weatherstrip has the advantages of simple structure and reasonable design. The polytetrafluoroethylene (PTFE) sponge core is used as the sealing material. PTFE has extremely superior chemical stability and very low friction coefficient, so that the car door-frame weatherstrip has higher elasticity and strength, longer service life and better sealing performance.

Description

technical field [0001] The invention relates to the technical field of automobile sealing strips, in particular to an automobile door frame sealing strip. Background technique [0002] Among polymer materials, rubber is widely used in shock-absorbing products due to its good mechanical properties and high resilience, and its elastic modulus is very small. But in general, the mechanical strength of rubber materials is low, the wear resistance is poor, the friction resistance generated during movement is large, and there are certain limitations in the resistance to media. [0003] The structure of traditional sealing strips for automobile door frames is complicated. The sealing strips are made of EPDM rubber into a solid straight strip structure. The sealing strips have small compression deformation and poor elasticity, so the sealing performance is relatively weak. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome...
