Efficient sealing strip for car door frame

Abstract

The invention relates to the technical field of car sealing strips, in particular to an efficient sealing strip for a car door frame. The efficient sealing strip comprises a U-shaped sealing componentand is characterized in that a first sealing component and a second sealing component are connected to the upper surface of the U-shaped sealing component, the first sealing component comprises a first rubber skin, the lower portion of the inner cavity of the first rubber skin is filled with a sponge core, and the upper portion of the inner cavity of the first rubber skin is a hollow cavity; thesecond sealing component comprises a second rubber skin, and the second rubber skin is connected to the upper surface of the U-shaped sealing component through a support part; the U-shaped sealing component comprises an outer rubber skin arranged outside and an inner rubber skin arranged inside, a steel sheet is arranged between the outer rubber skin and the inner rubber skin, inverted-pulling type clamp strips for facilitating the mounting of the sealing strip are arranged on the upper surface and the lower surface of the inner wall of the inner rubber skin, and the clamp strips on the uppersurface and the clamp strips on the lower surface are distributed in a staggered manner. The efficient sealing strip has the advantages that the sealing strip is simple in structure and reasonable indesign, the elasticity and strength of the sealing strip are increased, the service life of the sealing strip is prolonged, and the sealing performance of the sealing strip is increased.

Description

technical field [0001] The invention relates to the technical field of automobile sealing strips, in particular to a high-efficiency 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 invention is to o...
