Car window assembly and binding method thereof

Abstract

Disclosed are a car window assembly and a binding method thereof. The car window assembly comprises a transparent base and an integrated hard plastic layer covering at least three peripheral sides of the transparent base. The binding method of the car window assembly includes: providing the transparent base; forming the integrated hard plastic layer on the periphery of the transparent base by injection molding to cover at least three peripheral sides of the transparent base. Bond between the plastic layer and glass in the car window assembly is higher, no dislocation occurs, binding efficiency is higher, and production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of glass edge encapsulation, in particular to a vehicle window assembly and a method for encapsulating the vehicle window assembly. Background technique [0002] With the rapid development of automobile technology, the encapsulation products of vehicle glass are becoming more and more diverse and complex. Generally, a layer of soft plastic layer is formed by injection molding process around the glass, but because the strength of the soft plastic layer is relatively low, and it cannot prevent the intrusion of rainwater and air, etc., the protection ability of the glass is limited, thus affecting the window. Safety and service life of glass. [0003] refer to figure 1 As shown, in order to enhance the protective strength of the glass 100 , a hard plastic layer 200 may be formed on a part of the periphery of the glass 100 first, and then a soft plastic layer 300 may be formed. The specific forming process at...

AI Technical Summary

Problems solved by technology

[0006] 1. During the process of forming the soft plastic layer 300 through the injection molding process, since the hard plastic layer 200 is only suspended or stuck on the glass, and the injection pressure in the injection molding process is very high, the hard plastic layer 200 is relatively The glass 100 is prone to misalignment, which eventually leads to the inability to assemble the glass components to the vehicle, which affects the normal use of the glass components

[0007] 2. Since the hard plastic layer 200 and the glass 100 are bonded together through the soft plastic layer 300, the adhesion between the hard plastic layer 200 and the glass 100 is poor, thereby affecting the rigidity of the hard plastic layer 200. Protective effects

[0008] 3. Between the two injection molding processes, the hard plastic layer 200 and the glass 100 need to be placed together correspondingly, which leads to a relatively low efficiency of edge wrapping and increases the production cost

[0009] In addition, when the hard plastic layer 200 covers part of the upper surface, side surface and part of the lower surface of the glass 100 at the same time, that is, when the hard plastic layer 200 is in contact with the three sides of the glass 100 at the same time (referred to as three sides), if It is necessary to make the hard plastic layer 200 surround more than three surfaces of the glass 100 periphery at the same time, especially to make the hard plastic layer 200 surround all the periphery of the glass 100 at the same time, then the above-mentioned existing scheme cannot be realized.
