AI Technical Summary

Problems solved by technology

These residual stresses mechanically limit the service life of the components
[0009] In addition, if the visible part and the part to be attached are made of materials with different coefficients of expansion, differential expansion may occur during assembly, after assembly, or when the assembly is used on a vehicle
As a result, stresses are created at the weld points, which can lead to deformation or even separation of parts

Embodiment Construction

[0060] The fastening element 3 and the assembly 1 of the first part 2 of the motor vehicle made of plastic and the fastening element 3 will now be described. This assembly 1 is intended to enable the assembly of a first part 2 with a second part 4 of a motor vehicle.

[0061] In order to enable such an assembly, the fixing element 3 comprises a fixing portion 31 which can be fixed to the second part 4 . The fixing element 3 also comprises two supporting parts 32 which are arranged on both sides of the fixing part 31 and which are able to compress the first part 2 between the supporting parts 32 and the second part 4 . Finally, the fixing element 3 includes two connecting parts 33, each connecting part connects one end of the fixing part 31 and one end of a support part 32, each connecting part 33 forms a first bend 34 with the fixing part 31, and is connected with a corresponding The support portion 32 forms a second bent portion 35 .

[0062] In other words, the fixing port...

Abstract

The invention concerns an attachment element (3) for attaching a first motor vehicle part (2) made from plastic material to a second motor vehicle part (4) made from plastic material. The attachment element (3) comprises at least one attachment portion (31) suitable for being attached to the second part (4). The attachment element (3) also comprises at least one pressing portion (32) capable of compressing the first part (2) between the pressing portion (32) and the second part (4) and at least one connecting portion (33) linking the attachment portion (31) and the pressing portion (32), the connecting portion (33) forming a first bend (34) with the attachment portion (31) and forming a second bend (35) with the pressing portion (32).

Description

technical field [0001] The invention relates to the field of motor vehicles, in particular to components for the automotive industry comprising at least one plastic component. The invention relates more particularly to a component attached to a body element, notably by welding. Background technique [0002] Solutions are known for fastening a plastic part to another plastic part used as a body element. The component to be fixed may be a support for functional components of the vehicle, such as sensors, or a reinforcement such as a spoiler reinforcement attached to the outside of the spoiler. Known solutions use rivets, screws, snaps, especially gluing or welding. [0003] Among these solutions, some keep the appearance of the element for supporting the part intact, inter alia by avoiding depressions or visible fixing means. [0004] This is especially important when the body element supporting the component to be attached is visible. The part to be attached may be a rein...
