Door handle arrangement for vehicles

摘要

A door handle arrangement for vehicles including an electrically insulating cover having an outer actuating surface for a user characterized by at least one metal actuating electrode disposed on the inner side of the cover that is on the side of the cover facing away from the actuating surface. The cover is elastically deformable by an actuation in the area of the actuating surface. The arrangement includes at least one sensor electrode that is disposed at a distance from the actuating element and opposite the inner side of the cover, wherein the sensor electrode lies opposite the actuating electrode at least in certain sections so that the distance between actuating electrode and sensor electrode is variable during deformation of the cover in the region of the actuating surface. The arrangement also includes a control and evaluation device which is coupled at least to the sensor electrode to detect a capacitance between sensor electrode and actuating electrode.

1. A door handle arrangement for vehicles, comprising:
a body; an electrically insulating cover connected to the body and having an outer actuating surface for a user and a metal actuating electrode including a metal layer coupled to an inner side of the actuating surface, the actuating surface being elastically deformable by an actuation in the area of the actuating surface, a sensor electrode disposed at a distance from the actuating electrode and opposite the inner side of the actuating surface, wherein the sensor electrode is disposed within the body of the door handle arrangement and lies opposite the actuating electrode so that the distance between actuating electrode and sensor electrode is variable during deformation of the cover in the region of the actuating surface, at least one static spacer disposed between the actuating electrode and the sensor electrode and configured to maintain a spacing between the actuating electrode and a substrate supporting the sensor electrode; and a control and evaluation device in communication with the sensor electrode to detect a capacitance between the sensor electrode and the actuating electrode.
