Installation structure and installation method for sunroof installation plate and top cover

Abstract

The invention aims to provide an installation structure and an installation method for a sunroof installation plate and a top cover of an automobile, which have the advantages of convenient installation, stable structure and high intensity. In the invention, adhesive grooves are formed around the sunroof installation plate; a double-component epoxy resin structural adhesive is coated in the adhesive groove on a first side edge; wherein the double-component epoxy resin structural adhesive is composed of epoxy resin and polyamide curing agent; shock insulation adhesives are coated in the adhesive grooves on a second side edge, a third side edge and a fourth side edge; the second side edge, the third side edge and the fourth side edge of the sunroof installation plate are fixed with the top cover by welding; and the first side edge of the sunroof installation plate is fixed with the top cover by bonding through the double-component epoxy resin structural adhesive. In the installation structure for the sunroof installation plate and the top cover, the sunroof installation plate is fixed with three sides of the top cover by welding and the other side of the top cover is fixed by bonding through the double-component epoxy resin structural adhesive, so that the intensity of the sunroof installation plate is enhanced greatly, the deformation and collapse of the sunroof top cover can be avoided and the shock insulation effect of a sunroof can be ensured simultaneously.

Description

technical field [0001] The invention belongs to the technical field of automobile structures, and in particular relates to an installation structure and an installation method of an automobile sunroof installation plate and a top cover. Background technique [0002] The sunroof can bring better lighting and ventilation to the car, so it is very popular among users. Because the sunroof is exposed to the outside of the car body, it is greatly affected by the external environment of the car, so its design requirements are relatively high. At present, the installation structure of the skylight mounting plate and the top cover usually adopts the following three forms: 1. Three-sided welding, one side lapped structural form, and shock-absorbing glue is applied between the skylight mounting plate and the top cover sheet metal; 2. Three sides Welding, the structural form of one side hemming; 3, the structural form of all four sides hemming. The implementation process of the second...

AI Technical Summary

Problems solved by technology

The implementation process of the second and third structural forms is relatively complicated and the cost is high; while the implementation process of the first structural form is relatively simple, but its strength is weak, and there is a risk of roof collapse and deformation

Due to the influence of the space layout of the skylight, the structural strength of the skylight installation plate is insufficient, and the isolation glue is basically non-sticky, so the strength of the roof at side a is weak, and there is a risk of collapse and deformation
