Example Embodiment

[0010] The embodiment of the present invention: the method for improving the reliability of automobile seals, increasing the clamping force and friction coefficient of the sponge colloid clamping teeth on both sides of the inner wall of the dense colloid of the sealing strip, so as to reduce the influence of the tangential force on the automobile sealing strip; A tubular sponge colloid is arranged on the top of the dense colloid of the sealing strip to buffer the closing force and play the role of shock absorption and sound insulation.

[0011] The structure of the method for improving the reliability of automotive seals is as follows figure 1 As shown, the sealing strip compact colloid 3 is included, and sponge colloid clamping teeth 2 are provided on both sides of the inner wall of the sealing strip compact colloid 3, and an inverted U-shaped sealing strip steel belt 1 is arranged in the sealing strip compact colloid 3. A non-slip strip 6 is arranged on the tooth end of the ...

Abstract

The invention discloses a method and a device for improving reliability of an automobile seal element. Clamping force and friction coefficients of sponge rubber body clamping teeth on two sides of an inner wall of a compact rubber body of a seal strip are increased to reduce influence of tangential force on the automobile seal strip. A pipe-shaped sponge rubber body is arranged at the top of the compact rubber body of the seal strip to buffer closing force, and functions of shock absorption and sound insulation are achieved. According to the method and the device for improving reliability of the automobile seal element, by means of improvement on the compact rubber body of the automobile seal strip, anti-slipping belts are added on the clamping teeth of the sponge rubber body, and a seal strip steel belt is arranged in the compact rubber body of the seal strip, friction force and the clamping force between a substrate of the seal strip and a metal plate are remarkably improved to reduce the influence of the tangential force on the automobile seal strip and enable contact between the automobile seal strip and the metal plate to be tighter, and the phenomena of side slipping, wrinkle and the like of the automobile seal strip are effectively improved. In addition, the pipe-shaped sponge rubber body is added, and working performance of the automobile seal strip is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a method and a device for improving the reliability of an auto seal. Background technique [0002] Car doors, trunks, etc. are mainly sealed by sealing strips. At present, the usual automotive weather strips often do not fully match between the base of the fixed weather strip and the sheet metal. When the door, trunk and other components are opened and closed, the automobile weather strip is subjected to external forces, which will produce a certain shear. It is easy to cause the car seal to slip and wrinkle, which will cause the car seal to deform and fall off, affect the appearance, decoration and assembly of the car door, trunk, etc., and cause serious problems such as poor car seal and water leakage from the car body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and device for improving the reliability of au...
