Embodiment Construction

[0022] FIG. 1 shows a support structure 1 made of a magnesium alloy, which is fastened with its transverse ends 2 to an A-pillar of a motor vehicle. The supporting structure 1 serves to accommodate and mechanically support electronic components arranged in the region of the cockpit of the motor vehicle. For example, an instrument cluster is arranged in the left area 3 of the support structure, and a multimedia device is arranged in the middle area 4 . In its central region 4 , the supporting structure has a storage shelf 5 produced in one piece with the supporting structure 1 , on which a rear wall 6 belonging to the rear of the supporting structure 1 is likewise integrally formed. Electronic components 25 belonging to multimedia equipment, such as assembled printed circuit boards, are fixed on the storage rack 5 and are supplied with electrical energy and electronic information signals by means of plugs 7 . This plug 7 is located at the end of a plurality of cables 8 which f...

Abstract

An arrangement in a motor vehicle includes a support structure which is made of magnesium or of a magnesium alloy and includes at least one solid portion. Further, the arrangement includes an electronic component which is supported or held by the support structure, and a connection arrangement having a connection element which is at a prespecified electrical potential. At least one self-tapping screw is self-tapped into the solid portion of the support structure and thereby mechanically connects the support structure to the connection arrangement.

Description

technical field [0001] The invention relates to a device in a motor vehicle having: a supporting structure made of magnesium and / or a magnesium alloy; electronic components supported or accommodated by the supporting structure; at least one screw and a coupling, the coupling The part has a predetermined potential, in particular ground potential, wherein the support structure is mechanically connected to the coupling part by means of screws. Background technique [0002] A bearing structure made of magnesium for a motor vehicle is known, for example, from DE 103 17 900 A1, wherein the bearing structure is used for mechanically supporting an instrument panel unit in the cockpit of the motor vehicle. The bearing part is designed as a frame-like individual structural part and serves for additional stiffening of the motor vehicle body. [0003] DE 103 42 961 A1 likewise discloses a motor vehicle transverse support structure made of magnesium for supporting an instrument panel as...
