Angle-connecting structure and automobile door with angle-connecting structure

Abstract

The invention relates to the technical field of automobile body components and especially relates to an angle-connecting structure and an automobile door with the angle-connecting structure. The invention provides the angle-connecting structure which comprises a first extrusion part, a second extrusion part and an injection part used to connect the first extrusion part and the second extrusion part, wherein the injection part comprises a clamping part which is used to clamp a decorative panel; and an embedded part is inlaid in the injection part, the embedded part comprises a positioning supporting base and a framework plate disposed on the positioning support base, and at least a part of the framework plate is inlaid into the clamping part and used to support the clamping part. During operations, the first extrusion part, the second extrusion part and the embedded part are successively put into an injection mold; through injection molding, an injection part is made and connected to the above structure; the decorative panel is then clamped with the clamping part; operations are simple, and assembly time is short; and by the framework plate on the embedded part, reliability in connection between the decorative panel and the injection part is enhanced effectively, consumption of time and force is reduced and production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile body components, in particular to a corner structure and an automobile door provided with the corner structure, in particular to a corner structure with low cost, short assembly time and improved connection reliability and a The car door of the corner structure. Background technique [0002] In the traditional automobile window frame assembly line, after the pre-assembly of extrusion parts and injection molded parts is completed, the decorative panel is pressed onto the injection molded parts through interference fit or clearance fit. The disadvantage of this connection method is that if there is a calculation error or construction error, the decorative panel cannot be accurately installed on the injection molded part. At this time, it is necessary to adjust the size of the decorative panel or the injection molded part accordingly. It is beneficial to save the installation cost; in addition, t...
