Car window guide rail sealing strip capable of improving glass ascending and descending resistance and good in abrasion resistance

Abstract

The invention discloses a car window guide rail sealing strip capable of improving glass ascending and descending resistance and good in abrasion resistance. The sealing strip comprises a sealing strip body arranged along an upper frame of car window sheet metal, the lower end of the sealing strip body is provided with a groove allowing car window glass to be inserted, and the two side walls of the groove are each provided with a second inner lip, a third inner lip and a first outer lip which are in contact with the inner side face and the outer side face of the car window glass. The inner outer lips, the second inner lips and the third inner lips extend to the bottom face of the groove, TPE coatings are arranged on the outer side faces of the first outer lips and extend to wrap the bent heads of the first outer lips, TPE coatings are arranged on the outer side faces of the second inner lips and extend to the middles of the bent heads of the second inner lips, and flock layers are arranged on the outer side faces of the third inner lips and extend to the middles of the bent heads of the third inner lips. The TPE coatings are arranged on the surfaces of the first outer lips and the surface of the second inner lips and can effectively reduce friction force generated by the sealing strip body and ascending and descending of the car window glass, so that the sealing strip is more resistant to abrasion.

Description

technical field [0001] The invention relates to an automobile door and window guide rail sealing strip, in particular to a top strip structure in the glass window guide rail sealing strip. Background technique [0002] The car window is a liftable structure. For the stability of the car window glass lifting, four glass guide rails up, down, left, and right are arranged on the outer frame of the car window, and guide rail sealing strips are installed on the glass guide rails. As an important part of the car, the automotive glass guide rail sealing strip not only plays the role of sealing, but also plays the role of guiding and maintaining the glass running up and down. The integral glass guide rail sealing strip also plays the role of outer tube decoration. [0003] The structure of the contact part between the top strip section of the traditional automobile guide rail sealing strip and the window glass is flocked sealing lip, and the defect of the fluff structure is that the...

AI Technical Summary

Problems solved by technology

[0003] The structure of the contact part between the top strip section of the traditional automobile guide rail sealing strip and the window glass is flocked sealing lip, and the defect of the fluff structure is that the wear resistance between the fluff and the window glass is not enough and the friction resistance is large, and the fluff often passes through The window glass will drop after repeated lifting and lowering 300 times. Over time, the body rubber of the sealing lip will be worn, so that the sealing effect of the sealing strip will be reduced, and the dustproof, noiseproof and shockproof effects will be greatly affected.

The fluff implantation process has a certain impact on the environment, and it is easy to inhale and affect the health of the human body

And the product scrap rate caused by poor flocking is relatively high
