Bracket capable of quickly bonding and curing with window glass

Abstract

The invention relates to a bracket capable of quickly bonding and curing with window glass, and belongs to the technical field of automobile accessories. The bracket includes a bracket body and a pairof clamping platesarranged atthe upper end of the bracket body, convex ribs are arranged on the inner walls of the clamping plates, a PU adhesive is arranged in grooves formed by the convex ribs andglass, a group of air holes are formed in the clamping plates at intervals, and the ratio of the length J of the clamping plates to the spacing distance N between the air holes is 3 to 6; and the convex ribs include a group of main ribs which is located in the middle sections of the clamping plates and in contact with the glass surface and a group of side ribs which is located at both ends of theclamping plates, the height L of the main ribs is greater than the height S of the side ribs, and the ratio of the depth A of the clamping plates to the thickness C of the glass is 3 to 5. According to the automobile window glass bracket, through the air holes formed in the clamping plates, coordination of the main ribs and the side ribs and control of the depth of the clamping plates, the curingefficiency of the PU adhesive is greatly improved while the strength of the bracket is ensured, the installation cycle of the glass and the bracket is effectively shortened, and then the promoting effect on reducing the cycle inventory in a glass factory is achieved.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a car window fitting, in particular to a bracket capable of fast bonding and curing with car window glass. Background technique [0002] With the development of automobile technology, the overall performance requirements of body components are also continuously improved, and the stability and structural strength of related accessories are also put forward higher requirements. The side window glass of the car is connected with the lifter through the bracket to realize the lifting action of the glass. The bracket and the elevator are connected by threads, and the bracket and the glass are mostly bonded with a one-component moisture-curing PU (polyurethane) adhesive. The surface of the PU adhesive contains active -NCO groups, which can bond with the surface Or the trace moisture in the air reacts and solidifies. An existing bracket such as figure 1 As shown, the two sides and th...

AI Technical Summary

Problems solved by technology

An existing bracket such as figure 1 As shown, the two sides and the middle of the bracket splint are respectively provided with convex ribs, which clamp the glass, and the semi-closed cavity formed between the convex ribs and the glass stores PU glue, but since the two ends of the PU glue are closed, The contact area between PU glue and air is small, and the curing time of PU glue is long
