Problems solved by technology

The disadvantage is that the applicability of the proposed joining technology is only limited, since not every metallic structural element can be produced in a generative method; moreover, not least for cost reasons, and in the absence of structural elements The wider application of this method is not known in the case of forming a form-fit between cast and cast parts

Embodiment Construction

[0029] figure 1 A cross-sectional view of the joint between a structural component 1 made of plastic and a metal part 2 is shown. The structural component 1 made of plastic is shown abstractly and is therefore designed, not shown in more detail, as a carrier element, a holding element or, for example, as a housing of a lighting device of a vehicle, for example a headlight. The metal part 2 can form, for example, reinforcements, holders, holder tabs or the like.

[0030] A microstructure 10 is introduced into the surface of the metal part 2 which serves as a contact surface with the structural component 1 made of plastic, from which surface the microstructure enters obliquely into the body of the metal part 2 , wherein The inclination angles of the microstructures point in different directions relative to one another, by way of example a microstructure 10 on the left and an oppositely oriented microstructure 10 on the right are visible.

[0031] Microstructures 10 are introdu...

Abstract

The invention relates to a method for producing a joint connection between a structural component (1) and a metal component (2) of an illumination device of a vehicle, wherein the method comprises at least the following steps: generating a microstructure (10) in a joining surface of the metal component (2), wherein the microstructure (10) has undercuts in relation to the joining surface; softening the plastic material of the plastic component (1) in a near-surface region of the complementary joining surface by means of heat input; pressing together the plastic component (1) and the metal component (2) with a pressing force (F) in such a way that a part of the softened plastic material penetrates into the undercuts of the microstructure (10); cooling the plastic material of the plastic component (1), thereby restoring the strength of the softened plastic material of the plastic component (1).

Description

technical field [0001] The invention relates to a method for producing a joint connection between a structural component made of plastic and a metal part of a lighting device of a vehicle. Background technique [0002] A joining combination between a component made of plastic and a metal part is known from DE 10 2014 109 114 A1. For connecting the plastic component to the metal part, for example, a snap hook is shown on a first side and a threaded element on an opposite second side. This example shows that when constructing a lighting device for a vehicle, the connection between the plastic component and the metal part is often complex and requires a number of additional components, wherein while avoiding geometrically locked connections such as hooks and the like and / or when avoiding threaded elements, alternatively glued or clamped connections. It is also common to use retaining elements such as springs or the like. This disadvantageously results in a complex design an...
