Definitions

  • Capacitive control unit that can be operated in rotation with defined switching points
  • the invention relates to a rotationally operable capacitive operating unit, in which an operating element can be moved by a rotational movement relative to a fixed central element defining an axis of rotation and can be brought into electrical contact with it at predetermined contact points, the contact causing a local change in an electrical field, which can be detected by a capacitive sensor that is spatially separated and separated by a closed partition to trigger an assigned function.
  • capacitive touchscreens generally allow rotational operation, they often do not provide immediate haptic feedback or usually require direct visual contact for precise control.
  • capacitive switches such as those used in a keyboard and as they are known from US 2021/0320659 A1, usually only allow a single actuation to be recognized per capacitive sensor, with the addition that only orthogonal to a partition wall that spatially separates the sensor ongoing movements or operations can be recognized.
  • the control unit according to the document DE 10 2006 043 619 A1 also provides a partition wall that spatially separates the capacitive sensor, the control element being freely movable about an axis of rotation on the side of the partition facing away from the sensor, so that no defined switching or actuation points are determined or can be detected haptically.
  • the invention is therefore based on the object of overcoming the aforementioned disadvantages and of providing an operating unit which, on the one hand, enables a spatial separation of the operating element and a unit that recognizes the operation and, on the other hand, defines, in particular, in the circumferential direction around an axis of rotation about which the operating element can be operated in a rotational manner Provides switching points.
  • This task is achieved by the combination of features according to claim 1.
  • the at least one capacitive sensor is also arranged on the back of the partition and is designed to detect the respective local change in the electric field and to assign a respective position on the visible side of the partition to the respective local change.
  • the closed partition creates a complete spatial separation between the back arranged sensor and the control element arranged on the visible side, the control element being haptically detectable and actuable.
  • the control element can be moved mechanically to the defined switching points, at which stops and/or locking points can be provided to limit the movement of the control element.
  • an advantageous variant of the operating unit provides that the operating element has two contact sections arranged on the movement path and each assigned to a contact point for establishing the electrical contact at the respective contact point, which are electrically conductive or have conductive elements.
  • the contact sections of the operating element can also be formed integrally with one another as a continuous conductive section.
  • the middle element can each have a contact section at the contact points for producing the electrical contact at the respective contact point, which is electrically conductive or has conductive elements facing the control element.
  • the contact sections of the control element or the contact sections of the middle element can be designed as a contact pill or a snap disk.
  • the contact sections of the control element or the contact sections of the center element can have a contact pill or a snap disk.
  • a contact pill or a snap disk can be arranged between each contact section of the operating element and an associated contact section of the central element, with which the respective contact can be produced, in order to be able to provide a flat and uniform contact and, if necessary, a haptically detectable switching.
  • the contact points also preferably form a stop in the circumferential direction to limit the movement of the control element along the movement path.
  • control element can also be locked in one or both positions that establish contact at the contact point.
  • the operating unit has evaluation electronics connected to the capacitive sensor, which is designed to trigger a function to be switched that is assigned to the position. Additionally or alternatively, it can also be provided that the evaluation electronics determine a direction from the local changes in the electric field at the respective contact point detected by the at least one capacitive sensor and/or from the positions of the changes in the electric field determined by the at least one capacitive sensor into which the control element was moved. Based on the direction of actuation or the position of the change in the electric field, an assigned function can be triggered by the evaluation electronics.
  • Fig. 2 shows the first variant of the operating unit in an actuated position.
  • Figures 1 and 2 show an exemplary operating unit 1 with a pair of contact points A1, A2, with Figure 1 depicting the operating unit 1 in an unactuated position, ie in a neutral basic position, and Figure 2 depicting the operating unit 1 in an actuated position.
  • the capacitive operating unit 1 is shown in a top view, so that the plane in which the partition 10 runs corresponds to the representation plane, with the visible side of the partition 10 facing the viewer and the back of the partition 10 facing away from the viewer.
  • the middle element 20 fixed to the partition 10 is arranged, which is fixed and immovable in relation to its position relative to the partition 10. Furthermore, on the visible side of the partition 10, the operating element 30 is arranged, which is movably held on the central element 20 via the elastic element 40 designed as a torsion spring and thereby along the movement path B in the circumferential direction U around the axis of rotation X determined by the central element 20 and parallel to the Plane or parallel to the partition 10 can be rotated.
  • the operating element 30 is subjected to a force F from below in the plane of representation, as a result of which the operating element 30 is rotated along the movement path B in the circumferential direction U about the rotation axis X towards the first contact point A1, so that there is contact between the control element 30 and the middle element 20.
  • the electrical contact is established at the first contact point A1 by the first contact section 31 of the operating element 30 facing the first contact point A1 and the associated first contact section 21 of the middle element 20.
  • the two contact sections 31, 32 of the operating element 30 can be formed integrally with one another.
  • the contact sections 21, 22 of the middle element 20 can be formed, for example, by conductive plates which are fixed to an outer ring element 23 of the middle element 20.
  • the outer ring element 23 surrounds the elastic element 40 designed as a torsion spring and the inner central element 24 of the middle element 20.
  • the torsion spring or the elastic element 40 is supported on the central element 24 and/or the ring element 23 and holds the operating element 30 in a spring-returned position in the neutral basic position shown in FIG.
  • the operating element 30 can be used to control, for example, an electrically operable window or a vehicle door, the window being raised, for example, when contact occurs at the first contact point A1 and which is lowered. when contact occurs at the second contact point A2.
  • the door can be opened or closed by the respective contact.
