Conductive multi-layer panel intended for the cockpit of a vehicle, in particular a motor vehicle

Abstract

The invention relates to a conductive multi-layer panel intended for the cockpit of a vehicle, in particular a motor vehicle, and which is made conductive in order to meet the modern needs for the installation of a large number of electrical and electronic devices in said cockpit. The panel according to the invention comprises a multi-layer structure wherein one of the layers of the multi-layer structure is composed of a flexible printed circuit board (10). The flexible printed circuit board extends over substantially the entire surface of the panel or at least over a majority of the panel and is provided with an electrical connector (18) arranged at a location where electrical and electronic devices associated with the dashboard are subsequently mounted. Advantageously, the invention makes it possible to completely eliminate wired connections of electrical and electronic devices associated with an instrument panel for a cockpit of a vehicle, which makes it possible to simplify the electrical connections of these electrical and electronic devices and for subsequent maintenance and / or repair work.

Description

technical field [0001] The present invention relates to a conductive multilayer panel for the cockpit of a vehicle, in particular a motor vehicle. [0002] More particularly, the present invention relates to a conductive multilayer cover panel for the cockpit of a vehicle, in particular a motor vehicle. [0003] In particular, the present invention relates to a conductive multilayer cover panel for a cockpit of a motor vehicle, which meets the modern requirements for installing a large number of electrical and electronic devices inside said cockpit. [0004] The invention finds particular, but not exclusive, application in the manufacture of conductive instrument panels for vehicles, especially motor vehicles. . Background technique [0005] The cockpit front panel of a motor vehicle is generally defined as a blind bulkhead located below the windshield of the vehicle that defines the cockpit from the hood and engine compartment in the front. [0006] Using terminology der...

Problems solved by technology

[0015] Furthermore, as the number of electrical and electronic devices associated with an instrument panel or other covering panel increases, the complexity of the interventions used to achieve the aforementioned electrical connections also increases dramatically

[0016] Therefore, even with highly skilled labor, manufacturing time increases and the risk of human error cannot be ignored

[0017] Additionally, as the number of electrical and electronic devices associated with an instrument panel or other covering panel in the cockpit of a vehicle increases, the total weight of copper wire required for wired connections also increases significantly

[0018] This weight increase is considered a minor inconvenience due to ongoing efforts to limit the total weight of all vehicle components

[0019] In addition, an increase in the number of copper wires results in a significant increase in cost, both in the cost of the copper wire itself and in the cost of the accessories required to connect the copper wires

[0020] Another important disadvantage associated with the use of wired connections, where electrical connections are used for power transmission, is the risk of an increase in the temperature of the wires, which concerns the limitation of the maximum current that can pass through them: if an excessive current is passed through these wires, the The temperature increases, and the resistance increases; the increase in resistance causes the energy dissipation to increase, which increases the temperature

[0021] As a result, there is a risk of serious damage in the cockpit of the vehicle, and therefore an accident may occur
