Description

Die Erfindung betrifft einen Drehsteller für ein Kraftfahrzeug mit einem Bedienknopf, einem Gehäuse, einer am Bedienknopf drehfest befestigten Stellwelle und elektro-magnetischen Mitteln, die derart auf den Bedienknopf wirken, dass ein Rasten oder Blockieren der Drehbewegung des Bedienknopfs ermöglicht ist.The invention relates to a turntable for a motor vehicle with a control knob, a housing, a control knob rotatably mounted on the control shaft and electro-magnetic means which act on the control knob that a locking or blocking the rotation of the control knob is possible.

In heutigen Kraftfahrzeugen werden vielfach Bedienelemente eingesetzt, denen multifunktionale Steuerungsaufgaben zugeordnet sind. So kann über die Auswahl in einem Display oder Menütasten einem Drehsteller die Steuerungsaufgabe zufallen, die Lautstärke eines Rundfunkempfängers einzustellen und gleichzeitig die Steuerungsaufgabe zugeordnet werden, um ein dreistufiges Gebläse einzustellen. Hierbei sind in einem Drehsteller unterschiedliche Haptiken wie auch Begrenzungen als Endanschläge zu realisieren.In today's motor vehicles controls are often used, which are assigned multifunctional control tasks. Thus, via the selection in a display or menu keys, a turntable can be given the control task of adjusting the volume of a radio receiver and at the same time assigning the control task to set a three-stage blower. Here are in a turntable different haptics as well as limitations to realize as end stops.

Eine Möglichkeit zur Erzielung unterschiedlicher Rastpositionen in einem Drehsteller ist in der DE 101 53 002 A1 beschrieben. Der Drehsteller umfasst eine in einem Gehäuse drehbar gelagerte Stellwelle mit einer damit kooperierenden Rastanordnung, enthaltend ein drehbewegliches Halteelement, welches zur Aktivierung der Rastanordnung durch ein zugeordnetes durch einen Hubmagneten steuerbares Feststellelement bezüglich des Gehäuses brems- oder festlegbar ist, wobei der Hubmagnet einen aus einem Loch und einem beweglichen Ankeranordnung bestehenden Magnetkreis sowie eine Wicklung enthält. Hierbei enthält der Magnetkreis einen Permanentmagneten, welcher so ausgebildet und angeordnet ist, dass der Hubmagnet als bistabiler, durch kurzzeitige Bestromung der Wicklung umschaltbarer Hubmagnet wirkt. Durch die Anordnung einer Verzahnung und einer der die Verzahnung umgreifenden Rastring, die mit dem Hubmagneten zusammenwirkt, ist eine individuelle Einstellung der Rast möglich. Zur Erzeugung einer entsprechenden Haptik ist weiterhin die Verwendung bremszangenartiger Feststellelemente, welche auf die Oberfläche eines zumindest scheiben- oder ringsegmentartig ausgebildeten Rastelementes wirken beschrieben.One way to achieve different locking positions in a turntable is in the DE 101 53 002 A1 described. The turntable comprises a rotatably mounted in a housing actuating shaft with a cooperating detent arrangement comprising a rotatable support member which is to brake the activation of the locking arrangement by an associated controllable by a solenoid locking element with respect to the housing or fixable, the solenoid from a hole and a movable armature arrangement existing magnetic circuit and a winding contains. In this case, the magnetic circuit includes a permanent magnet, which is designed and arranged so that the solenoid acts as a bistable, by short-term energization of the winding switchable solenoid. The arrangement of a toothing and one of the toothing encompassing locking ring, which cooperates with the lifting magnet, an individual adjustment of the catch is possible. To produce a corresponding feel, the use of brake pliers-like locking elements, which act on the surface of an at least disc-shaped or ring-segment-like locking element, is also described.

Die Aufgabe der Erfindung ist es einen Drehsteller bereitzustellen, mit dem es möglich ist, beliebige Haptikverläufe zu erzeugen. Darüber hinaus soll der Drehsteller konstruktiv einfach aufgebaut und kostengünstig zu fertigen sein.
Dokument EP1480238 zeigt einen Drehsteller nach dem Oberbegriff des Anspruchs 1.
Die erfindungsgemäße Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object of the invention is to provide a turntable with which it is possible to produce any desired haptics. In addition, the turntable should be structurally simple and inexpensive to manufacture.
document EP1480238 shows a turntable according to the preamble of claim 1.
The object of the invention is achieved by the features of claim 1.

Durch den erfindungsgemäßen Aufbau des Drehstellers ist nun die Möglichkeit geschaffen, beliebige Haptikverläufe an einem Bedienknopf des Drehstellers zu realisieren. Dies ist insbesondere dann vorteilhaft, wenn der Drehsteller für multifunktionale Steuerungsaufgaben eingesetzt wird. So sind erfindungsgemäß viele kleine Rasten wie auch Mittenrasten und Endanschläge darstellbar. Hierbei unterscheiden sich die üblichen Rasten von den Mittenrasten dadurch, dass bei Mittenrasten ein im Gegensatz zu normalen Rasten ein erhöhter Kraftaufwand zum Überdrehen der Mittenrast notwendig ist. Durch eine formschlüssige Verbindung zwischen der Reibscheibe und der Stellwelle sowie zwischen dem Flußführungsteil und der Stellwelle ist ein konstruktiv einfacher Aufbau der magnetischen Mittel gewährleistet, was sich wiederum positiv auf die Herstellungskosten auswirkt.The inventive construction of the turntable, the possibility is now created to realize any Haptikverläufe on a control knob of the turntable. This is particularly advantageous when the turntable is used for multifunctional control tasks. Thus, according to the invention many small notches as well as center pegs and end stops can be displayed. In this case, the usual detents differ from the center detents in that in the case of center detents, in contrast to normal detents, an increased expenditure of force for over-rotating the center detent is necessary. By a positive connection between the friction disc and the actuating shaft and between the flux guide member and the actuating shaft a structurally simple construction of the magnetic means is ensured, which in turn has a positive effect on the manufacturing cost.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment.

Es zeigt:It shows:

Figur 2FIG. 2

Wie aus der Figur 1 ersichtlich, besteht der Drehsteller 1 aus einem Bedienknopf 2 an dem eine Stellwelle 3 drehfest befestigt ist. Unterhalb des Bedienknopfs ist an der Welle ein Flußführungsteil 4 sowie eine Reibscheibe 5 entlang der Stellwelle 3 bewegbar befestigt. Das Flußführungsteil 4 und die Reibscheibe 5 sind entlang der Stellwelle 3 und in Richtung des Pfeils P über die Stellwelle 3 hinweg bewegbar. Erfindungsgemäß ist eine formschlüssige Verbindung, wobei die Stellwelle 3 zumindest im Bereich des Flußführungsteils 4 und der Reibscheibe 5 profiliert ausgebildet ist und dass Flußführungsteil 4 und die Reibscheibe 5 eine dem Profil entsprechende Öffnung aufweisen vorgesehen. Unterhalb der Reibscheibe 5 ist eine Spule 6 um die Stellwelle 3 herum angeordnet. Die Spule 6 wird in einem Teil des Gehäuses 7 des Drehstellers 1 gehalten. Das Gehäuse 7 trägt gleichzeitig die Lagerung 8 der Stellwelle 3. Vorstellbar ist es hier ein handelsübliches Lager, wie beispielsweise ein Gleitlager, Rollenlager oder Kugellager einzusetzen.Like from the FIG. 1 it can be seen, the turntable 1 consists of a control knob 2 on which a control shaft 3 is rotatably mounted. Below the control knob, a flux guide member 4 and a friction washer 5 along the control shaft 3 is movably mounted on the shaft. The flux guide part 4 and the friction disk 5 are movable along the control shaft 3 and in the direction of the arrow P over the control shaft 3 away. According to the invention, a positive connection, wherein the control shaft 3 is formed profiled at least in the region of the flux guide part 4 and the friction disc 5 and that flux guide member 4 and the friction disc 5 a provided the profile corresponding opening. Below the friction disc 5, a coil 6 is arranged around the control shaft 3 around. The coil 6 is held in a part of the housing 7 of the turntable 1. The housing 7 at the same time supports the bearing 8 of the control shaft 3. It is conceivable here to use a commercial bearing, such as a plain bearing, roller bearings or ball bearings.

Die im Gehäuse 7 aufgenommene Spule 6 kann entweder als umlaufende, das heißt um die Stellwelle 3 herumlaufend oder als separates Spulenelement an zwei oder mehr Positionen im Gehäuse aufgenommen sein. Wird die Spule 6 mit Strom beaufschlagt, so indiziert die Spule 6 ein magnetisches Feld das beispielsweise in Richtung der gestrichelten Linie L durch das Gehäuse 7 und das Flußführungsteil 4 verläuft. Bevorzugt ist das Gehäuse 7 wie auch das Flußführungsteil aus einem elektrisch leitenden Werkstoff gebildet. Ist das Gehäuse 7, das die Spule 6 aufnimmt aus einem elektrisch leitenden Werkstoff gebildet, so bildet das Gehäuse 7 ein unteres den magnetischen Fluß führendes Teil 7 und das Flußführungsteil 4 ein oberes den magnetischen Fluß führendes Teil 4.The coil 6 accommodated in the housing 7 can be accommodated either as a circumferential one, that is to say around the setting shaft 3 or as a separate coil element at two or more positions in the housing. If the coil 6 is energized, the coil 6 indicates a magnetic field which, for example, runs in the direction of the dashed line L through the housing 7 and the flux guide part 4. Preferably, the housing 7 as well as the flux guide member is formed of an electrically conductive material. If the housing 7 accommodating the coil 6 is formed of an electrically conductive material, then the housing 7 forms a lower part 7 conducting the magnetic flux, and the flux guide part 4 forms an upper part 4 guiding the magnetic flux.

Wird nun die Spule 6 mit einem elektrischen Strom beaufschlagt, so erzeugen die magnetischen Feldlinien eine Kraft F, die das Flußführungsteil 4 gegen die Reibscheibe 5 an das Gehäuse 7 und die Spule 6 anpresst. Je nach Höhe der Anpresskraft F wird eine für den Bediener des Bedienknopfs 2 unterschiedliche Haptik am Drehsteller 1 erkennbar. Es ist somit ein beliebiges Rastmuster, das heißt in Bezug auf die Rastabstände und Rastkräfte am Bedienknopf einstellbar. So ist es erfindungsgemäß möglich viele kleine Rasten sowie Mittenrasten und Endanschläge frei zu programmieren. Die Programmierung erfolgt hierbei dadurch, dass die Spule 6 in den den Rasten entsprechenden Abständen seitlich begrenzt mit Strom durchflossen wird, so dass die der Rast entsprechende Kraft F auf das Flußführungsteil ausgeübt wird und somit durch die formschlüssige Verbindung zur Stellwelle 3 eine Bremswirkung am Bedienknopf 2 spürbar ist.Now, if the coil 6 is acted upon by an electric current, the magnetic field lines generate a force F, which presses the flux guide member 4 against the friction disc 5 to the housing 7 and the coil 6. Depending on the height of the contact force F, a different feel for the operator of the control button 2 on the turntable 1 can be seen. It is thus an arbitrary detent pattern, that is adjustable with respect to the locking distances and locking forces on the control knob. So it is possible according to the invention to freely program many small notches and center pegs and end stops. The programming takes place in this case in that the coil 6 is traversed laterally in the distances corresponding to the notches with current, so that the force corresponding to the detent F is exerted on the flux guide part and thus by the positive connection to the control shaft 3 a braking effect on the control knob. 2 is noticeable.

Alternativ ist es möglich, das Flußführungsteil 4 ohne die Reibscheibe 5 zu verwenden. Die Reibscheibe 5 ist erfindungsgemäß bereichsweise und ringförmig mit einer Beschichtung 9, die einseitig oder beidseitig der Reibscheibe 5 anbringbar ist, ausführbar. Die Beschichtung 9 dient hierbei dazu, die Adhäsionskräfte zwischen den magnetischen Mitteln 4, 7, 6 zu reduzieren. Gleichzeitig dient die Beschichtung 9 als Gleitmittel zwischen den sich relativ zueinander bewegenden Flußführungsteilen 4, 7. Als Beschichtung 9 sind hierbei Werkstoffe einsetzbar, die eine geringere Festigkeit als der Grundwerkstoff der Flußführungsteile 4, 7 aufweisen. Ein einzusetzender Werkstoff ist hierbei beispielsweise Kupfer. In einer bevorzugten Ausführungsform ist die Beschichtung 9 ringförmig auf der Reibscheibe 5 aufgebracht.Alternatively, it is possible to use the flux guide member 4 without the friction washer 5. According to the invention, the friction disk 5 can be made in regions and in a ring shape with a coating 9 which can be attached on one or both sides of the friction disk 5. The coating 9 serves to reduce the adhesion forces between the magnetic means 4, 7, 6. At the same time, the coating 9 serves as a lubricant between the flux guide parts 4, 7 which move relative to one another. As the coating 9, it is possible to use materials which have a lower strength than the base material of the flux guide parts 4, 7. A material to be used here is for example copper. In a preferred embodiment, the coating 9 is annularly applied to the friction disc 5.

Um die Drehbewegungen des Bedienknopfes 2 auswerten zu können, ist es erfindungsgemäß möglich, an die Stellwelle 3 einen Winkelgeber 10 zu befestigen. Als Winkelgeber 10 werden hierbei die aus dem Stand der Technik bekannten üblichen Winkelgeber 10 eingesetzt. In dem Fall, in dem die elektromagnetischen Mittel 4, 5, 6, 7 einen Endanschlag realisieren, werden die magnetischen Mittel 4, 5, 6, 7 gegeneinander gepresst. Um aus dieser Stellung heraus die magnetischen Mittel 4, 5, 6, 7 wieder zu lösen wird einerseits ein hochsensibler Winkelgeber 10 eingesetzt, der auch minimalste Drehbewegungen des Bedienknopfes 2 in die dem Endanschlag entgegengesetzte Richtung detektiert und hierbei die magnetischen Mittel 4, 5, 6, 7 freigibt und andererseits ist das Spiel, mit dem das Flußführungsteil 4 und die Reibscheibe 5 in der Stellwelle 3 aufgenommen sind ausreichend um den Bedienknopf 2 minimal zu drehen, so dass mittels das Winkelgebers 10 die Drehrichtung erfasst und die magnetischen Mittel 4, 5, 6, 7 freigegeben werden.In order to evaluate the rotational movements of the control knob 2, it is possible according to the invention to attach an angle encoder 10 to the control shaft 3. As an angle encoder 10 here known from the prior art conventional angle encoder 10 are used. In the case where the electromagnetic means 4, 5, 6, 7 realize an end stop, the magnetic means 4, 5, 6, 7 are pressed against each other. In order to release the magnetic means 4, 5, 6, 7 again from this position, on the one hand a highly sensitive angle sensor 10 is used, which detects even the most minimal rotational movements of the control knob 2 in the opposite direction to the end stop and in this case the magnetic means 4, 5, 6 7, and on the other hand, the play with which the flux guide part 4 and the friction disc 5 are received in the control shaft 3 is sufficient to turn the control knob 2 minimally, so that by means of the angle encoder 10 detects the direction of rotation and the magnetic means 4, 5, 6, 7 are released.

Neben dem Spiel des Flußführungsteils 4 und der Reibscheibe 5, wobei das Spiel in Drehstellern 1 unerwünscht ist, ist es erfindungsgemäß möglich, ein elastisches Element 11 in die Stellwelle 3 einzubringen, um eine Relativbewegung zwischen dem Winkelgeber 10 und den magnetischen Mitteln 4, 5, 6, 7 zu ermöglichen und somit ein Lösen der Kraft F einzuleiten. Als elastisches Element 11 ist hierbei ein Werkstoff einsetzbar, der eine Torrosion, wenn auch nur geringfügig, zulässt, da im Wesentlichen der Winkelgeber für den Impuls zum Lösen der Kraft F verantwortlich ist. Eine bevorzugte Position für ein entsprechendes elastisches Element 11 ist in die Stellwelle 3 der Figur 2 gestrichelt eingezeichnet.In addition to the game of Flußführungsteils 4 and the friction disc 5, wherein the game in turntables 1 is undesirable, it is possible according to the invention to introduce an elastic element 11 in the control shaft 3 to a relative movement between the angle encoder 10 and the magnetic means 4, 5, 6, 7 and thus initiate a release of the force F. As elastic element 11 in this case a material can be used, which allows toroidal, albeit only slightly, since essentially the angle encoder is responsible for the pulse to release the force F. A preferred position for a corresponding elastic element 11 is in the control shaft 3 of FIG. 2 dashed lines.
