Definitions

  • door handles for motor vehicles are mainly made of electrically non-conductive material, preferably made of plastic.
  • an antenna coil is integrated into the door handle for communication with an ID transmitter.
  • the modern trend of the automotive industry is to chrome again the door handles, as it was formerly common practice.
  • the invention has for its object to provide a way to still chrome door handles with integrated antenna coil.
  • the winding axis of the antenna coil can basically be oriented arbitrarily.
  • the antenna coil which preferably contains a ferrite core, aligned with its axis approximately in the longitudinal direction of the door handle, so that their winding planes are transverse to the longitudinal direction of the door handle.
  • the invention further provides a door handle housing of electrically non-conductive material, preferably of plastic, having a cavity for receiving an antenna coil and having an outer coating of electrically conductive material, wherein the coating has an interruption, the the formation of a closed, the antenna coil transverse to the winding axis rotating electrical Leitpfades prevented.

    caractérisée en ce que la poignée de porte porte un revêtement (1) en matériau électroconducteur et en ce que le revêtement (1) présente au moins une interruption (4), qui empêche la formation d'un chemin électroconducteur fermé entourant la bobine d'antenne (3) transversalement à son axe d'enroulement.
  2. Poignée de porte selon la revendication 1, caractérisée en ce que le revêtement (1) est aplati sur les bords de l'interruption (4).
  3. Poignée de porte selon la revendication 1, caractérisée en ce que l'interruption (4) du revêtement (1) est remplie d'un matériau non électroconducteur.
  4. Poignée de porte selon l'une quelconque des revendications 1 à 3, caractérisée en ce que l'axe d'enroulement de la bobine d'antenne (3) se trouve dans la direction longitudinale de la poignée de porte et en ce que l'interruption (4) du revêtement (1) s'étend dans la direction longitudinale de la poignée de porte.
  5. Poignée de porte selon la revendication 4, caractérisée en ce que l'interruption (4) du revêtement (1) s'étend sur la face interne de la poignée de porte.
  6. Boîtier de poignée de porte en matériau non électroconducteur, de préférence en matériau synthétique, comprenant une cavité (2) destinée à recevoir une bobine d'antenne (3),
    caractérisé par un revêtement externe (1) en matériau électroconducteur, lequel revêtement (1) présente une interruption (4) qui empêche la formation d'un chemin électroconducteur fermé entourant la bobine d'antenne (3) transversalement à son axe d'enroulement.
  7. Procédé pour appliquer un revêtement externe (1) en matériau électroconducteur sur un boîtier de poignée de porte en matériau non électroconducteur, de préférence en matériau synthétique, dans lequel le boîtier présente une cavité (2) destinée à recevoir une bobine d'antenne (3),
    une couche conductrice étant appliquée sur le boîtier et le revêtement (1) étant appliqué par voie électrolytique sur la couche conductrice,
    caractérisé en ce que
    le revêtement (1) est doté d'une interruption qui empêche la formation d'un chemin électroconducteur fermé entourant la bobine d'antenne (3) transversalement à son axe d'enroulement.
  8. Procédé selon la revendication 7, caractérisé en ce que l'on élimine la couche conductrice dans la zone de l'interruption avant d'appliquer le revêtement.
  9. Procédé selon la revendication 8, caractérisé en ce que l'on élimine la couche conductrice dans la zone de l'interruption par rayonnement laser.
  10. Procédé selon la revendication 7, caractérisé en ce que la couche conductrice est recouverte dans la zone de l'interruption pendant l'application du revêtement et ensuite éliminée.
