Abstract
Official abstract text for this publication.
An actuating device for a movable part, in particular a cover of a vehicle body opening, including at least one actuator and at least one electromechanical switching element, wherein the electromechanical switching element can be brought from a first mode into a second mode by means of the actuator, wherein in the first mode the electromechanical switching element senses an actuation by means of the actuator and in the second mode the electromechanical switching element releases the actuator such that the actuator can be moved toward the movable part, wherein the electromechanical switching element has an electroactive polymer and/or a piezoelectric element.
First claim
Opening claim text (preview).
What is claimed is: 1 . An actuating device for a movable part, the actuating device comprising: at least one actuator; and at least one electromechanical switching element that is adapted to be brought from a first mode into a second mode by the actuator, wherein, in the first mode, the electromechanical switching element senses an actuation by the actuator, wherein, in the second mode, the electromechanical switching element releases the actuator such that the actuator is movable toward the movable part, and wherein the electromechanical switching element has an electroactive polymer and/or a piezoelectric element. 2 . The actuating device according to claim 1 , wherein an electronic unit controls the first and second modes of the electromechanical switching element. 3 . The actuating device according to claim 1 , wherein a first spring element acts on the actuator, as a result of which a position of the actuator is adapted to be changed. 4 . The actuating device according to claim 1 , wherein a locking mechanism, which is adapted to be brought into an open position and a closed position by the electromechanical switching element, is arranged on the electromechanical switching element, and wherein the locking mechanism is operatively connected to at least one second spring element. 5 . The actuating device according to claim 1 , wherein a mechanical emergency mechanism is provided, with which the movable part is adapted to be actuated, and wherein the movable part is adapted to be released from a closed position into an open position. 6 . The actuating device according to claim 1 , wherein the actuator has at least one activation element and/or at least one pressure element. 7 . The actuating device according to claim 1 , wherein the electromechanical switching element and/or the electronic unit are connectable to a control device of a vehicle, a central locking system and/or a passive entry system of a vehicle. 8 . The actuating device according to claim 1 , wherein at least one further electromechanical switching element is provided, which senses an authorized opening operation. 9 . The actuating device according to claim 1 , wherein the electromechanical switching element is adapted to be switched into the second mode only after a sensing operation. 10 . The actuating device according to claim 1 , wherein the movable part is a cover of a vehicle body opening.
