Sealing system of vehicle window glass

Abstract

The invention relates to a sealing system, in particular to a sealing system of vehicle window glass. The sealing system of the vehicle window glass is used for connecting a windshield with a water tank cap. The sealing system of the vehicle window glass comprises the windshield, the water tank cap, a hook-shaped sealing piece and a sealing lip, wherein the cross section of the hook-shaped sealing piece is in a hook shape. The hook-shaped sealing piece comprises a maintaining portion and an elastic arm. The outer side of the maintaining portion adheres to the inner side of the windshield. The elastic arm is tightly buckled with a rib of the water tank cover in a sealed mode. The sealing lip is tightly arranged between the lower edge of the windshield and the upper edge of the water tank cap in a matched mode and is flush with the outer surface of the windshield and the outer surface of the water tank cap. The sealing system of the vehicle window glass is characterized in that a glue containing groove used for containing an adhesive or a self-adhesive tape is formed in the outer side of the maintaining portion, a glue storage groove is formed in the maintaining portion, and at least one row of through holes which are longitudinally arranged along the maintaining portion are formed between the glue containing groove and the glue storage groove. The sealing system of the vehicle window glass has the advantages that the adhesive strength is improved, and the production cost is reduced.

Description

Technical field: [0001] The invention relates to a sealing system, in particular to a sealing system for vehicle windows. Background technique: [0002] The sealing system of the existing automobile windshield usually attaches a hook seal to the lower edge of the glass. As described in patent CN102007010A, the hook seal includes a retaining part fixed on the inner side of the glass, and an embedded rib of the water tank cover. snap-fit ​​elastic arms, and a sealing lip tightly fitted between the lower edge of the windshield and the upper edge of the water tank cover. There are through holes in the holding part, and the fluid adhesive can reach the contact surface between the holding part and the inside of the glass through these through holes. In order to ensure the relative position between the windshield and the holding part after the bonding is completed, it can be The relative positions of the windshield and the holding part are first fixed by the tooling, and then the ...

AI Technical Summary

Problems solved by technology

[0004] 1) When applying glue to the through hole of the holding part, the adhesive has a certain fluidity, and it is easy to overflow and cause waste;

[0005] 2) When applying glue to the through hole of the holding part, there is no guarantee that the adhesive can completely fill the gap between the holding part and the glass, and sufficient bonding strength cannot be achieved;

[0006] 3) In addition, due to the core structure made of metal materials, the production cost is inevitably increased
