Definitions
- the invention relates to a switching device, in particular in motor vehicles, comprising a control surface exhibiting a user interface.
- the invention relates to a switching device which is housed, for example, on the vehicle steering wheel or in the area of the doors or the dashboard or the center console and is used for the operation of several functions.
- Recent vehicle switching devices typically have a smooth, continuous surface under which multiple sensors are housed to service various devices in the vehicle.
- the continuous user interface on the control element results in a high-quality design.
- the individual control panels, which are assigned to the individual sensors, are usually identified by symbols which are illuminated by the panel being partially translucent.
- the sensors that are behind the control element are pressure-sensitive or touch-sensitive. In the case of pressure-sensitive sensors, it is customary for the operating element to yield slightly in the respective control panel, for example due to its inherent elasticity. Since the shift stroke is thus below the perception limit for the operator, the operating element is moved laterally by an electric drive to achieve a haptic feedback for the operator.
- This minimum lateral movement can not be distinguished by the operator himself from a yielding or deflection of the operating element, so that it is simulated to him a kind of clicking or clicking a switch as feedback of a switching operation.
- This electric motor usually includes an electrical Haptikaktuator which is mechanically coupled to the control element and this shifts when triggering a switching signal to generate a haptic feedback signal.
- the haptic actuator includes a coil and an anchor. The anchor is stored in the coil with one or two end stops, which he encounters when reciprocating.
- the object of the invention is to improve a switching device, especially in vehicles so that the switching device is subject to less wear and very quiet operation.
- a switching device having a control surface having a control panel, an electrical Haptikaktuator which is mechanically coupled to the control panel and this shifts when triggering a switching signal to generate a haptic feedback signal, wherein the Haptikaktuator a coil, a displaceable by the coil Anchor and at least one internal end stop for the armature movement has, and wherein the control element is mounted and coupled to the Haptikaktuator that the working stroke of the Haptikaktuators is located away from the end stop.
- the switching device according to the invention provides that the intended so far within the coil or on the coil end stop for the anchor is no longer used, since the working stroke, ie the working range of the armature is located away from the end stop.
- the haptic actuator starting from its end stop has a force-displacement characteristic with a force maximum removed from the end stop and a force minimum lying between the end stop and maximum force, wherein the working stroke of the actuator lies in a section remote from the end stop.
- a force-displacement characteristic with a force maximum removed from the end stop and a force minimum lying between the end stop and maximum force, wherein the working stroke of the actuator lies in a section remote from the end stop.
- a ferromagnetic core adjoining the coil has a different thickness in the region of the working stroke, preferably a thickness increasing from an initial position of the coil in the working stroke to the deflection position .
- the ferromagnetic core can also essentially completely surround the coil, that is to say have a circumferential hollow profile cross section. In the range of different thickness, for example, an air gap is executed. Due to the smaller iron cross-section in the region of reduced thickness, the field line absorption capacity in this area decreases, conversely, the magnetic saturation and the force increase with the cross-sectional increase in the ferromagnetic core.
- the thickness of the ferromagnetic core continuously increases toward the deflection position. It is particularly effective if the ferromagnetic core or at least the part of the ferromagnetic core, which has the different thickness, is located between coil and armature.
- an elastic return element which pushes back the operating element and the armature from a position deflected by the coil to a starting position.
- This return element can rest directly on the anchor or on the operating element.
- the operating element is, as already explained above, preferably linearly displaceably mounted transversely to the direction of the switching operation.
- the GmbHbetuschistscardi is usually perpendicular to the user interface directed or, if the user interface is curved, perpendicular to the area of the user interface, which has the operating panel to be operated.
- the working stroke can be defined by two stops, between which a mechanically coupled to the armature, to be moved part is linearly displaceable.
- This part to be moved is in particular the operating element itself.
- this provides a significant advantage because it can come to no long tolerance chains, as far as the position and extent of the power stroke.
- the actuated part itself, namely the operating element, is to be moved between its stops.
- a housing lower part may be provided, on which the two stops are formed.
- the lower housing part may have a recess with two opposite wall sections, which form the two stops.
- An extension of the part to be displaced projects into the recess and alternately strikes against the wall sections when the actuator is actuated.
- the housing base can with a recording geometry for recording and
- Haptikaktuators be formed, which may be formed, for example, in a lower housing part made of plastic as wells in the injection mold.
- the switching device is substantially rigidly mounted, for example, in the direction of the switching operation and has at least one touch-sensitive sensor. This means that there is no need for a sliding bearing for the operating element, which in turn could lead to gaps to the adjacent part exist.
- the touch-sensitive sensor requires no deformation of the operating element, but rather it is sufficient to touch the operating element at a corresponding point in order to generate a switching signal.
- a variant of the invention provides that the switching device has at least one touch-sensitive, in particular capacitive sensor and / or at least one pressure-sensitive sensor, which detects the actuation of the operating element.
- the control is z.
- B. a one-piece part with several adjacent panels, which in each case at least one sensor is assigned to detect the operation of this panel.
- a switching device preferably in motor vehicles, characterized in that the switching device has a control surface exhibiting control element, an electrical Haptikaktuator which is mechanically coupled to the control element and this triggering a switching signal to generate a haptic feedback signal transversely to the direction of the switching operation in a shift direction along a linear bearing shifts, wherein the linear bearing has at least one extending in the direction of displacement rod and at least one sliding member which sits on the rod and relative to the rod along its displaceable, and wherein the operating element is mounted in addition to the linear bearing via a clip connection , which prevents pivoting of the control element around the rod and allows movement of the operating element in the direction of displacement.
- the clip connection is provided here between the control element and the lower housing part, but this is not to be understood as limiting.
- the rod is a very simple type of linear bearing, but this is only part of the linear bearing.
- the switching device according to the invention provides, on the other hand, that the operating element is additionally simple is mounted via a clip connection.
- the clip connection is particularly executed, it holds the control on the other part only against pivoting, but not against moving in the linear direction.
- the control element is thus fastened in the region of the linear bearing on the other part and pivoted in the direction of this part, to be finally easily clipped.
- the rod may be a separately manufactured part, in particular a metal wire or a metal rod, which is held over at least one bearing block.
- the bearing block for example, integrally formed on the inside of the control element, that is usually be molded, which does not generate additional manufacturing costs. The rod can then be easily inserted laterally or longitudinally into the bearing block or clipped.
- the linear bearing can run along an edge of the operating element and the clip connection can be provided on the opposite edge in order to generate the highest possible stability.
- a switching device with a user interface having control element, which has at least one control panel, which is associated with both a touch-sensitive, especially capacitive sensor and a pressure-sensitive sensor, the two sensors so are designed that together they trigger an operating function.
- the solution according to the invention provides that two sensors, namely a touch-sensitive and additionally a pressure-sensitive sensor, are available for the same operating function and the same control panel.
- two sensors namely a touch-sensitive and additionally a pressure-sensitive sensor
- the resolution for sensing the The operator's fingers can be significantly increased, false tripping or inadvertent triggering of functions assigned to the adjacent control panel can be avoided. Only when both sensors strike, that is detect a finger and detect a pressure, the control panel is considered to be actuated, and an operating function associated with this panel is triggered.
- the pressure-sensitive sensor is preferably spaced from the operating element in the interior of the switching device.
- For power transmission is on the inside of the control element for each control panel, in particular designed as a light guide element pressure plunger available. This plunger passes a force applied to the control panel pressure force to the underlying pressure-sensitive sensor.
- a particularly effective embodiment of the invention provides that a capacitor plate of the pressure-sensitive sensor at the same time forms a capacitor plate of a touch-sensitive sensor. Both sensors are therefore capacitive sensors. Due to the dual function of having a capacitor plate, parts and space can be saved to a considerable extent.
- the switching devices in vehicles are extremely small, but still have tolerance chains through the many existing parts. With the low switching paths or with the high detection accuracy, it is important that the parts are positioned exactly to each other.
- the present invention further provides for a simplified construction and for ensuring the starting positions of parts, in particular in the area of the operating element and the sensor system. This is achieved by a switching device, with a one
- control element having at least one control panel, which is associated with a touch-sensitive sensor, wherein an elastically formed, electrically conductive, with a capacitor plate of the at least one touch-sensitive sensor electrically coupled Toleranzaus Eisenseelement is provided between two adjacent parts.
- the elastic tolerance compensation element has a double function. On the one hand, it has a mechanical function in that it is clamped between two adjoining parts, so that it pushes these parts away from each other in the area of the sensor and the operating element and thus positions in starting positions. The tolerance compensation element thus fills a gap within the tolerance chain, which has a slightly different dimension in each switching device.
- the second function is an electrical function, because the tolerance compensation element increases the sensitive area of the sensor and moves it closer to the operating element so that the sensitivity of the touch-sensitive sensor is increased.
- the tolerance compensation element can be accommodated biased in a space between an end facing away from the control element of the plunger and an adjacent part.
- the tolerance compensation element on the pressure-sensitive sensor and its triggering has a beneficial effect.
- the plunger is always pressed by the tolerance compensation element in a starting position, so that no return spring must be provided.
- the tolerance compensation element in the region of the holding projection may have a complementary recess, so that it can not be moved out of its position during the vibrations in the vehicle or during actuation.
- the tolerance compensation element it is possible to use the tolerance compensation element as a restoring element for the operating element, in particular for an associated operating field.
- the restoring element pushes the operating element back from an engaged switching position into an initial position.
- the control element can be rigidly mounted in the operating direction and be elastically deformable for actuating the pressure-sensitive sensor, so that in this case the tolerance compensation element does not have to perform a reset function.
- Options for constructive design of the tolerance compensation element include, inter alia, this plate-shaped form and / or of electrically conductive plastic, such as foam to produce.
- a separate tolerance compensation element is provided for each control panel, and the tolerance compensation elements are spaced apart to exclude any mutual interference.
- the pressure-sensitive sensor is a capacitive sensor, it is advisable to electronically couple the tolerance compensation element with the adjacent capacitor plate of the pressure-sensitive sensor, wherein the tolerance compensation element in this case is preferably between this capacitor plate and the control element, whereby this capacitor plate so to speak towards the user interface is extended, whereby the sensor has a sensor area which is moved further to the operating element.
- this capacitor plate may also be a common capacitor plate of the pressure-sensitive and the touch-sensitive sensor.

- the operating element 12 is partially transparent or translucent.
- the user interface 14 is smooth, and there is no gap between the control panels 16. Rather, the control element 12 is designed as a continuous, one-piece, substantially rigid body.
- the outer housing of the switching device 10 is not only from the cup-shaped control element 12, but also from a lower housing part 18 arranged underneath, which is also executed cup-shaped and made of plastic.
- Each control panel 16 has its own sensor system which detects the actuation of the corresponding function and the corresponding device in the vehicle.
- a separate sensor system is present for each control panel 16.
- a touch-sensitive sensor and in addition also a pressure-sensitive sensor is provided for each control panel 16, which detect the actuation of the control element at the appropriate location.
- Both the touch-sensitive and the pressure-sensitive sensor is designed as a capacitive sensor in this embodiment.
- a printed circuit board 20 with corresponding circuits carries on its upper side associated with the operating element 12 in the region of each control panel 16 a thin metal layer, for example of copper, which forms the lowermost capacitor plate 22 of the pressure-sensitive sensor.
- a thin elastic film 24 or adhesive layer By a thin elastic film 24 or adhesive layer, the capacitor plate 22 is electrically separated from an overlying capacitor plate 26.
- the two flexible capacitor plates 22, 26 thus form the pressure-sensitive sensor 28.
- the pressure-sensitive sensor 28 may already be finished on the printed circuit board 20, or each of these pressure-sensitive sensors 28 may be a finished part, which is placed later on the printed circuit board 20 and is electrically connected to it.
- the tolerance compensation element 30 is designed to be electrically conductive and is in electrical connection with the capacitor plate 26 in order to lengthen or thicken the capacitor plate 26 toward the operating element 12.
- the capacitor plate 26 together with elastic tolerance compensation element 30 also forms the capacitor plate of the touch-sensitive sensor 32, which detects the touching of the user interface 14 in the region of the associated control panel 16.
- the capacitor plate 26 has a dual function by being associated with both sensors 28, 32.
- the plate-shaped or disk-shaped tolerance compensation element 30 has a central recess 34 into which a retaining projection 36 of a light guide element 38 protrudes to fix the tolerance compensation element 30 laterally.
- the light guide element 38 is, as the name implies, made of plastic and is there, the light of an associated LED 40, which sits on the printed circuit board 20 (see Figure 3) and is introduced laterally into the light guide element 38, to forward the control element 12, to backlight the corresponding symbol.
- the light guide element 38 touches the underside of the control element 12 and is biased by the tolerance compensation element 30 slightly upward, since the tolerance compensation element 30 biased between two adjacent parts, namely the light guide element 38 and the sensor 28 and thus the printed circuit board 20 is seated.
- the light guide element 38 is at the same time a push rod, because it passes the minimum deflection when pressing or pressing the control element 12, which is rigidly mounted in the operating direction A, in the pressure-sensitive sensor 28.
- the minimum deflection during operation is preferably carried out by elastic deformation of the control element 12th
- the pressure-sensitive sensor 28 is so sensitive that the interposition of the tolerance compensation element 30 is not detrimental to the detection of a shift operation.
- the tolerance compensation element 30 supports at least the provision of the operating element 12 in the starting position from the engaged switching position and can serve as a restoring element here. If the operating element 12 is not rigidly mounted, but yielding in the operating direction A, then the tolerance compensation element 30 may even be the only return element.
- the deflection (working) of the operating element 12 is only a few tenths of a millimeter, preferably about 0.2 mm.
- the control element 12 is mounted laterally movable.
- This storage is a linear bearing by a rod 48 extends at a longitudinal edge 46 of the lower housing part 18, which is preferably made of metal and thus separately and which sits firmly in molded on the lower housing part 18 bearing blocks 50.
- the control element 12 has on its underside also molded sliding elements 51, which also sit on the rod 48, but which are provided with a minimum clearance to the rod 48 so that the control element 12 can be moved linearly along the rod 48 or pivoted to her could be.
- a clip connection 54 between the control element 12 and housing lower part 18 is formed, which prevents the pivoting of the control element 12.
- the clip connection 54 comprises a tab 56 with a window, which is formed on the control element 12, and a hook-shaped projection 58, which in turn is formed on the lower housing part 18 (see also Figure 2).
- the clip connection acts in the pivoting direction, ie in the direction of the
- the Haptikaktuator 44 includes a coil 60, which is surrounded by a hollow ferromagnetic core 62, which is made of several parts and a first ring 64 and a laterally pushed over second ring 66 includes. Inside the coil 60 and the ferromagnetic core 62 is seated a linearly displaceable armature 68 which, as shown in FIGS. 4 and 5, is mounted via a receiving geometry 70 integrally formed in the housing lower part 18.
- a corresponding receiving geometry is also present for the rest of Haptikaktuators 44, as Figure 5 shows.
- the armature 68 is coupled to the operating element 12 via a rib 74 which is clipped into a groove 72 in the armature 68 and protrudes on the underside of the operating element 12.
- the rib 74 is designed in the region of the groove 72 so that it sits in the axial direction in the groove 72 without play, so that every smallest movement of the armature 68 leads to a deflection of the operating element 12.
- the Haptikaktuator 44 would have its maximum force actually when the armature 68 would abut the stop, here the magnet 82. However, since this initial position can not be reached consciously, the electromagnet used is designed such that it has in its force-displacement diagram (see FIG. 8) a second maximum 91, in the region H of which the working stroke h is laid. Due to the possible tolerances, it is difficult to determine the exact position of the working stroke h from the outset. For this reason, the range H is selected so that the working stroke h always lies in a region within the larger region H, which still ensures a high force exerted on the armature 68.
- This second maximum force 91 is achieved in that the ferromagnetic core 62 is unevenly thick.
- one of the two rings, here the ring 66, on its circular cylindrical inner wall has a tapered end 92 over which the thickness becomes progressively smaller toward the end.
- the field line occupancy becomes lower in this area, and conversely, the magnetic saturation and the cross-sectional gain force increase toward the magnet 82.
- the force minimum between the maximum at deflection 0 (corresponding to the position of the armature 68 at the stop) and the second maximum force 90 in the force-displacement diagram of the haptic actuator 44 is denoted by reference numeral 94.
