Abstract
A control element for use, for example with a vehicle is disclosed. The control element includes at least one tubular section with a cavity at least partially surrounded by a wall, and a piezoelectric component. The piezoelectric component is arranged in the cavity and generates a haptic signal at at least one partial region of the control element and/or detects the action of pressure on at least one part of the piezoelectric component. Furthermore, the vehicle with the control element is also specified.
Claims14
A control element, comprising:
- at least one tubular section with a cavity at least partially surrounded by a wall;
- and
- a piezoelectric component arranged in the cavity, the piezoelectric component being configured to generate a haptic signal in at least a partial region of the control element and to detect an action of pressure on at least a part of the piezoelectric component, the piezoelectric component further comprising:
- a piezoelectric actuator having a longitudinal direction;
- and
- at least one mechanical amplification element attached to the piezoelectric actuator such that a change in length of the piezoelectric actuator along the longitudinal direction, when a voltage is applied, moves a portion of the at least one mechanical amplification element in a direction perpendicular to the longitudinal direction, and when no voltage is applied, the action of pressure deforms the at least one mechanical amplification element to cause the length of the piezoelectric actuator to change, thereby generating an electrical signal that triggers a predefined function by the control element.
