Description

High-reliability connecting structure for decorating part and foaming instrument board

Technical Field

The utility model relates to the field of automotive technology, concretely relates to decoration and foaming instrument board connection structure of high reliability.

Background

For the connection of the decoration and the foaming instrument board, the current mainstream vehicle model generally adopts the milling of the instrument board after foaming to penetrate through the skin/foam layer/framework, and then the decoration is clamped on the milled and formed structure in a clamping and buckling mode and the like. The fixing mode has simple process and convenient installation, but is limited by larger tolerance of milling process, the connection reliability is usually lower, and the problems of poor fastening, poor clearance surface, product scrapping and the like are easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a decoration and foaming instrument board connection structure of high reliability to the not enough of above-mentioned technique, reliable and stable has effectively solved the connection/outward appearance that brings because of milling great process tolerance/condemned waiting pain point.

In order to realize the purpose, the utility model discloses a high reliability's decoration and foaming instrument board connection structure includes epidermal layer, foam blanket and casing ply in proper order, the outside of casing ply is equipped with the skeleton groove, the casing ply is located the thickness of skeleton groove bottom position is less than the thickness of casing ply, the casing ply is located the thickness of casing ply border position is greater than the thickness of casing ply, the casing ply is located the open pore is cut to casing ply bottom position and forms the skeleton hole, the width in skeleton hole is greater than the width in skeleton groove, the tip of ornamental strip is equipped with the buckle, the buckle stretches into the skeleton hole card is in on the border of casing groove.

Preferably, the thickness of the framework layer at the bottom of the framework groove is 2.0-2.2 mm, and the framework layer is a part removed by a milling process after foaming.

Preferably, the thickness of the framework layer at the edge of the framework groove is 4.5-4.7 mm, and the buckle is guaranteed to be clamped on an injection molding structure.

Preferably, the diameter of the framework groove is 8.3-8.5 mm, and the buckle is guaranteed to be clamped on an injection molding structure.

Preferably, the diameter of the skeleton hole is 11.5-11.7 mm, and the skeleton hole is a part removed by a milling process after foaming.

Preferably, the skin layer is formed by a slush molding, male molding or injection molding process, the foam layer is formed by POLY/ISO chemical foaming, the skeleton layer is formed by an injection molding process, and the decorative strip is formed by a paint, electroplating, INS or IMD process.

Compared with the prior art, the utility model, but the buckle direct joint is structural at injection moulding's product, and not only simple to operate is reliable and stable moreover, has effectively solved the connection/outward appearance/condemned waiting pain point that brings because of milling great process tolerance.
