This object is achieved in an operating device of the generic type according to the invention that the input device can be inserted into an outside recess of the housing of the HMI device and, if necessary, the recess can be removed.
Das spritzwasserdichte Gehäuse des erfindungsgemäßen Bediengeräts weist eine der Anzahl der zum Einsatz kommenden Eingabevorrichtungen entsprechende Anzahl von Vertiefungen auf, so dass jede Eingabevorrichtung in einer Montagerichtung in eine zugeordnete Vertiefung des Gehäuses eingesetzt werden kann. Die Vertiefungen sind auf der Außenseite des Gehäuses angeordnet, beispielsweise auf dessen Oberseite. Dies erleichtert die Montage und den Austausch der Eingabevorrichtungen, da es zum Einsetzen einer Eingabe- Vorrichtung in eine außenseitige Vertiefung des Gehäuses nicht erforderlich ist, das spritzwasserdichte Gehäuse zu öffnen. Soll eine Eingabevorrichtung ausgetauscht werden, so kann sie der Vertiefung entnommen werden, wobei der Austausch erfolgen kann, ohne das Gehäuse zu öffnen. Insbesondere kann der Austausch erfolgen, ohne dass die Gefahr besteht, dass eine Dichtung des Gehäuses beschädigt wird. The splash-proof housing of the operating device according to the invention has a number of recesses corresponding to the number of input devices used, so that each input device can be inserted in an assembly direction into an associated recess of the housing. The recesses are arranged on the outside of the housing, for example on its upper side. This facilitates the assembly and replacement of the input devices since it is necessary to insert an input device. Device in an outside recess of the housing is not required to open the splash-proof housing. If an input device is to be replaced, then it can be removed from the depression, wherein the replacement can take place without opening the housing. In particular, the replacement can be done without the risk that a seal of the housing is damaged.
Von Vorteil ist es, wenn die Eingabevorrichtung eine vormontierbare Baueinheit ausbildet, denn dies gibt die Möglichkeit, die Eingabevorrichtung in Form einer Baueinheit in eine Vertiefung des Gehäuses einzusetzen. It is advantageous if the input device forms a preassemblable unit, because this gives the possibility of inserting the input device in the form of a structural unit in a recess of the housing.
Wie eingangs erwähnt, kann die Drehstellung und/oder Drehstellungsänderung des Signalgebers vom zugeordneten Sensorelement erfasst werden, so dass das Sensorelement der Steuer- und Übertragungselektronik des Bediengeräts ein von der Drehstellung und/oder Drehstellungsänderung des Signalgebers abhängiges Sensorsignal bereitstellen kann. As mentioned above, the rotational position and / or rotational position change of the signal generator can be detected by the associated sensor element, so that the sensor element of the control and transmission electronics of the operating device can provide a dependent of the rotational position and / or rotational position change of the signal sensor sensor signal.
Das Zusammenwirken des Signalgebers und des Sensorelements kann berührungsbehaftet erfolgen. So kann beispielsweise vorgesehen sein, dass das im Gehäuse des Bediengeräts angeordnete Sensorelement als Drehpotentiometer ausgebildet ist und dass der am zugeordneten Drehglied angeordnete Signalgeber in Form eines Mitnehmers ausgestaltet ist, der mit dem Drehpotentiometer in Eingriff steht. The interaction of the signal generator and the sensor element may be touch-sensitive. Thus, for example, be provided that arranged in the housing of the control unit sensor element is designed as a rotary potentiometer and that the arranged on the associated rotary member signal generator is designed in the form of a driver, which is in engagement with the rotary potentiometer.
Von besonderem Vorteil ist es, wenn der Signalgeber mit dem Sensorelement berührungslos zusammenwirkt, denn dadurch kann eine manuelle Beeinträchtigung des zugeordneten Sensorelements durch den Signalgeber verhindert werden. Das berührungslose Zusammenwirken von Signalgeber und Sensorelement hat darüber hinaus den Vorteil, dass das Sensorelement die Drehstellung und/oder Drehstellungsänderung des Signalgebers auch dann erfassen kann, wenn zwischen dem Signalgeber und dem Sensorelement ein Wandabschnitt des Gehäuses des Bediengeräts angeordnet ist. Der Wandabschnitt kann vorzugsweise aus einem Kunststoffmaterial gefertigt sein, das das Erfas- sen der Drehstellung und/oder Drehstellungsänderung durch das Sensorelement praktisch nicht beeinträchtigt. Ein berührungsloses Zusammenwirken des Signalgebers mit dem Sensorelement erlaubt es daher, die Vertiefung des Gehäuses, die die Eingabevorrichtung aufnimmt, ohne Durchbrechungen auszugestalten. Der Signalgeber kann somit ebenso wie die restlichen Bestandteile der Eingabevorrichtung vollständig an der Außenseite des Gehäuses angeordnet sein und muss nicht etwa in den Innenraum des Gehäuses hineinragen. Dies erleichtert die Montage und den Austausch der Eingabevorrichtung . It is particularly advantageous if the signal transmitter cooperates contactlessly with the sensor element, because this can prevent a manual impairment of the associated sensor element by the signal generator. The non-contact interaction of signal generator and sensor element has the additional advantage that the sensor element can detect the rotational position and / or rotational position change of the signal generator even if a wall portion of the housing of the operating device is arranged between the signal generator and the sensor element. The wall section may preferably be made of a plastic material that satisfies the requirements of sen the rotational position and / or rotational position change by the sensor element practically not affected. A non-contact interaction of the signal transmitter with the sensor element therefore makes it possible to design the recess of the housing, which accommodates the input device, without perforations. The signal generator can thus be arranged completely on the outside of the housing as well as the remaining components of the input device and does not have to protrude approximately into the interior of the housing. This facilitates the assembly and replacement of the input device.
Es kann beispielsweise vorgesehen sein, dass der Signalgeber als Permanentmagnet ausgestaltet ist und das dem Signalgeber zugeordnete Sensorelement magnetfeldempfindlich ist. Durch Betätigung des Tastenkopfs der Eingabevorrichtung kann die Drehstellung des am Drehglied angeordneten Permanentmagneten verändert werden, und dies wiederum hat zur Folge, dass sich die Richtung des vom Permanentmagneten erzeugten Magnetfelds ändert. Die Richtungsänderung kann von dem magnetfeldempfindlichen Sensorelement erfasst werden, das daraufhin der Steuer- und Sendeelektronik des Bediengeräts ein entsprechendes Sensorsignal bereitstellen kann. It can be provided, for example, that the signal generator is designed as a permanent magnet and the signal transmitter associated sensor element is sensitive to magnetic fields. By operating the key top of the input device, the rotational position of the permanent magnet disposed on the rotary member can be changed, and this in turn has the consequence that the direction of the magnetic field generated by the permanent magnet changes. The change in direction can be detected by the magnetic-field-sensitive sensor element, which can then provide the control and transmission electronics of the operating device with a corresponding sensor signal.
Der Permanentmagnet ist günstigerweise quer zur Drehachse des Drehglieds magnetisiert. The permanent magnet is conveniently magnetized transversely to the axis of rotation of the rotary member.
Bevorzugt weist die mindestens eine Bedienungseinrichtung ein die Eingabevorrichtung umgreifendes Verbindungselement auf, das auf die Eingabevorrichtung aufsetzbar und mit dem Gehäuse lösbar verbindbar, insbesondere verschraubbar ist. The at least one operating device preferably has a connecting element encompassing the input device, which can be placed on the input device and detachably connected to the housing, in particular screwed.
Bezogen auf eine Montagerichtung kann das Verbindungselement die Eingabevorrichtung hintergreifen. Relative to a mounting direction, the connecting element can engage behind the input device.
Die Eingabevorrichtung kann in eine außenseitige Vertiefung des Gehäuses eingesetzt werden und das Verbindungselement kann auf die Eingabevorrich- tung aufgesetzt und mit dem Gehäuse lösbar verbunden werden, so dass die Eingabevorrichtung in der Vertiefung des Gehäuses festgelegt ist. The input device can be inserted into an outside recess of the housing and the connection element can be placed on the input device. tion and be detachably connected to the housing, so that the input device is fixed in the recess of the housing.
Das Verbindungselement ist bei einer vorteilhaften Ausführungsform der Erfindung nach Art eines Überwurfringes ausgestaltet, der mit dem Gehäuse ver- schraubbar ist. In an advantageous embodiment of the invention, the connecting element is designed in the manner of a coupling ring, which can be screwed to the housing.
Bevorzugt weist die Vertiefung des Gehäuses eine Stützfläche auf und die Eingabevorrichtung weist ein Tragteil auf, das sich, vorzugsweise unter Zwischenlage eines Dichtelements, beispielsweise eines Dichtringes, an der Stützfläche abstützt. Beim Einsetzen der Eingabevorrichtung kann das Tragteil auf der Stützfläche aufsitzen, so dass in einer Montagerichtung auf das Tragteil einwirkende Kräfte von der Stützfläche aufgenommen werden können. Preferably, the recess of the housing has a support surface and the input device has a support member which, preferably with the interposition of a sealing element, for example a sealing ring, is supported on the support surface. When inserting the input device, the support member may rest on the support surface, so that forces acting on the support member in an assembly direction can be absorbed by the support surface.
Die Stützfläche kann beispielsweise eine Verengung der Vertiefung des Gehäuses ausbilden, insbesondere ein Stufe, über die sich der Durchmesser der Vertiefung verringert. The support surface may, for example, form a constriction of the recess of the housing, in particular a step, over which the diameter of the recess is reduced.
Günstig ist es, wenn das Drehglied und der am Drehglied drehfest gehaltene Signalgeber einen Abstand zum Gehäuse einnehmen, so dass die Drehbewegung des Drehglieds und des Signalgebers durch das Gehäuse nicht beeinträchtigt wird. It is advantageous if the rotary member and the rotationally fixed to the rotary member held signal transmitter occupy a distance from the housing, so that the rotational movement of the rotary member and the signal generator is not affected by the housing.
Bevorzugt bildet das Tragteil eine Halterung für das Drehglied aus. Bei einer derartigen Ausgestaltung der Erfindung hat das Tragteil nicht nur die Funktion, die Eingabevorrichtung an einer Stützfläche abzustützen, sondern das Tragteil hat zusätzlich eine Haltefunktion für das Drehglied. Das Drehglied ist am Tragteil axial unbeweglich und drehbar gehalten. Preferably, the support member forms a holder for the rotary member. In such an embodiment of the invention, the support member not only has the function to support the input device on a support surface, but the support member additionally has a holding function for the rotary member. The rotary member is axially immovable and rotatably supported on the support member.
Das Tragteil weist bei einer vorteilhaften Ausgestaltung der Erfindung eine Führungshülse auf, an der das Drehglied drehbar gehalten ist. Von Vorteil ist es, wenn die Eingabevorrichtung ein elastisch verformbares Deckelteil aufweist. Das Deckelteil kann beispielsweise in Form eines Balges ausgestaltet sein. The support member has in an advantageous embodiment of the invention, a guide sleeve on which the rotary member is rotatably supported. It is advantageous if the input device has an elastically deformable cover part. The lid part can be configured, for example, in the form of a bellows.
Günstig ist es, wenn das Deckelteil aus einem elastisch verformbaren Kunststoffmaterial ausgestaltet ist. It is advantageous if the cover part is made of an elastically deformable plastic material.
Das elastisch verformbare Deckelteil untergreift bei einer vorteilhaften Ausgestaltung der Erfindung den vom Benutzer manuell betätigbaren Tastenkopf. The elastically deformable cover part engages under an advantageous embodiment of the invention, the manually operable by the user key top.
Von besonderem Vorteil ist es, wenn der Tastenkopf mit dem Deckelteil spritzwasserdicht verbunden ist. It is particularly advantageous if the key top is connected splash-tight with the cover part.
Die Drehachse des Drehglieds ist vorteilhafterweise kollinear zur Längsachse der Eingabevorrichtung ausgerichtet. The axis of rotation of the rotary member is advantageously aligned collinear with the longitudinal axis of the input device.
Wie bereits erwähnt, wird eine lineare Bewegung des Tastenkopfs über die Kopplungsmechanik in eine rotatorische Bewegung des Drehglieds übertragen. Zu diesem Zweck weist die Kopplungsmechanik bei einer vorteilhaften Ausführungsform der Erfindung einen am Tastenkopf gehaltenen Stößel auf, der über einen Mitnehmer und einen Führungsschlitz mit dem Drehglied gekoppelt ist, wobei der Mitnehmer in den Führungsschlitz eintaucht und sich der Führungsschlitz bezogen auf die Längsachse kurvenförmig in axialer Richtung und in Umfangsrichtung erstreckt. Der Stößel ist mit dem Tastenkopf verbunden und kann zusammen mit dem Tastenkopf entlang der Längsachse bewegt werden. Die lineare Bewegung des Stößels wird über den Mitnehmer und den Führungsschlitz, in die der Mitnehmer eintaucht, in eine rotatorische Bewegung des Drehglieds übertragen. As already mentioned, a linear movement of the key top is transmitted via the coupling mechanism into a rotary movement of the rotary member. For this purpose, in an advantageous embodiment of the invention, the coupling mechanism has a ram held on the key head, which is coupled via a driver and a guide slot with the rotary member, wherein the driver dips into the guide slot and the guide slot with respect to the longitudinal axis curved in axial Direction and extends in the circumferential direction. The plunger is connected to the key top and can be moved along with the key top along the longitudinal axis. The linear movement of the plunger is transmitted via the driver and the guide slot into which the driver dips in a rotational movement of the rotary member.
Der Führungsschlitz ist kurvenförmig nach Art einer Wendel ausgebildet und erstreckt sich sowohl in axialer Richtung als auch in Umfangsrichtung. Der Mitnehmer und der Führungsschlitz bilden somit eine Steuerkulisse aus, die eine lineare Bewegung in eine rotatorische Bewegung überträgt. Günstig ist es, wenn der Mitnehmer drehfest am Stößel gehalten ist und der Führungsschlitz am Drehglied angeordnet ist. The guide slot is curved in the manner of a helix and extends both in the axial direction and in the circumferential direction. The driver and the guide slot thus form a control link, which transmits a linear movement in a rotational movement. It is advantageous if the driver is held against rotation on the plunger and the guide slot is arranged on the rotary member.
Es kann beispielsweise vorgesehen sein, dass der Mitnehmer stiftförmig ausgebildet ist und mit mindestens einem Ende in radialer Richtung aus dem Stößel herausragt, wobei er mit seinem herausragenden Ende in einen Führungsschlitz des Drehglieds eintaucht. It can be provided, for example, that the driver is pin-shaped and protrudes with at least one end in the radial direction of the plunger, wherein it dips with its protruding end in a guide slot of the rotary member.
Von Vorteil ist es, wenn der Mitnehmer als Mitnahmestift ausgestaltet ist, der den Stößel diametral durchgreift und mit seinen beiden Enden jeweils in einen Führungsschlitz des Drehglieds eingreift. It is advantageous if the driver is designed as a driving pin, which passes through the plunger diametrically and engages with its two ends in each case in a guide slot of the rotary member.
Die mindestens eine Eingabevorrichtung erlaubt bevorzugt eine stufenlose Befehlseingabe, indem sich die Drehstellung des Drehglieds in Abhängigkeit vom Ausmaß der Hubbewegung des Tastenkopfs kontinuierlich verändert. The at least one input device preferably allows a stepless command input by continuously changing the rotational position of the rotary member in dependence on the extent of the stroke movement of the key top.
Häufig ist es hilfreich, wenn dem Benutzer bei Erreichen einer oder mehrerer Hubstellungen des Tastenkopfs eine taktile Rückmeldung bereitgestellt wird, denn dies erleichtert die Handhabung des Bediengeräts. Hierzu weist die mindestens eine Eingabevorrichtung bei einer bevorzugten Ausgestaltung der Erfindung mindestens ein Rastelement auf mit einem Rastkopf, dem zumindest eine Rastvertiefung zugeordnet ist, in die der Rastkopf bei Erreichen einer vorgegebenen Hubstellung des Tastenkopfs eintaucht. Das Eintauchen des Rastkopfes in eine Rastvertiefung gibt dem Benutzer eine taktile Rückmeldung, anhand derer er erkennen kann, dass der Tastenkopf eine bestimmte Hubstellung erreicht hat. It is often helpful to provide tactile feedback to the user when one or more key head strokes are reached, as this facilitates handling of the keypad. For this purpose, the at least one input device in a preferred embodiment of the invention, at least one locking element with a locking head, which is associated with at least one detent recess into which the locking head dips upon reaching a predetermined stroke position of the key head. The immersion of the locking head in a detent recess gives the user a tactile feedback, by which he can see that the key head has reached a certain stroke position.
Bevorzugt ist der Rastkopf in Richtung der Rastvertiefung elastisch vorgespannt. Preferably, the locking head is resiliently biased in the direction of the locking recess.
Günstig ist es, wenn dem mindestens einen Rastelement mehrere bezogen auf die Längsachse in Reihe hintereinander angeordnete Rastvertiefungen zuge- ordnet sind, in die der Rastkopf des Rastelements bei einer Hubbewegung des Tastenkopfs nacheinander eintaucht. Wird der Tastenkopf vom Benutzer entlang der Längsachse bewegt, so taucht der Rastkopf bei Erreichen vorgegebener Hubstellungen jeweils in eine Rastvertiefung ein und gibt damit dem Benutzer eine taktile Rückmeldung über das Erreichen der jeweiligen Hubstellung . Dies erleichtert die Handhabung des Bediengeräts insbesondere in Fällen, in denen der Benutzer das Bediengerät mit Handschuhen betätigt. It is advantageous if the at least one latching element has a plurality of latching recesses arranged one behind the other in series with respect to the longitudinal axis. are arranged, in which the locking head of the locking element during a stroke movement of the key head is successively immersed. If the key head is moved by the user along the longitudinal axis, the latching head, upon reaching predetermined lifting positions, respectively dips into a detent recess and thus gives the user a tactile feedback about the reaching of the respective stroke position. This facilitates the handling of the HMI device, in particular in cases where the user operates the HMI device with gloves.
Von besonderem Vorteil ist es, wenn die mindestens eine Rastvertiefung an die Form des zugeordneten Rastkopfes angepasst ist. Dies erlaubt eine nicht nur punktförmige sondern linienförmige oder flächige Anlage des Rastkopfes an der Rastvertiefung. Dadurch kann der Verschleiß der mindestens einen Rastvertiefung und des Rastkopfes gering gehalten werden. It is particularly advantageous if the at least one latching recess is adapted to the shape of the associated latching head. This allows not only punctiform but linear or planar contact of the locking head on the locking recess. Thereby, the wear of at least one locking recess and the locking head can be kept low.
Bei einer bevorzugten Ausgestaltung der Erfindung ist dem mindestens einen Rastelement eine parallel zur Längsachse ausgerichtete Laufrille zugeordnet, in die der Rastkopf des Rastelements permanent eintaucht, wobei die mindestens eine, dem Rastelement zugeordnete Rastvertiefung in der Laufrille angeordnet ist. Die Laufrille erstreckt sich parallel zur Längsachse der Eingabevorrichtung, und bei einer Bewegung des Tastenkopfs gleitet der Rastkopf des der Laufrille zugeordneten Rastelements entlang der Laufrille. Der Rastkopf taucht somit permanent in die Laufrille ein, unabhängig von der Hubstellung des Tastenkopfs. Die mindestens eine Rastvertiefung ist in der Laufrille angeordnet, so dass der Rastkopf in die Rastvertiefung eintaucht, wenn der Tastenkopf eine vorgegebene Hubstellung erreicht hat. In a preferred embodiment of the invention, a parallel to the longitudinal axis aligned groove is assigned to the at least one locking element, in which the locking head of the locking element permanently immersed, wherein the at least one, the locking element associated latching recess is arranged in the raceway. The track groove extends parallel to the longitudinal axis of the input device, and upon movement of the key top, the latching head of the latching element associated with the track groove slides along the track groove. The locking head thus permanently immersed in the groove, regardless of the stroke position of the key head. The at least one detent recess is arranged in the groove, so that the detent head dips into the detent recess when the key head has reached a predetermined stroke position.
Von Vorteil ist es, wenn die Form der Laufrille an die Form des in die Laufrille eintauchenden Rastkopfes angepasst ist, denn dadurch kann der Verschleiß der Laufrille und des Rastkopfes gering gehalten werden. It is advantageous if the shape of the track groove is adapted to the shape of the dipping into the track groove locking head, because the wear of the track groove and the locking head can be kept low.
Es kann beispielsweise vorgesehen sein, dass der Rastkopf kugelförmig ausgestaltet ist und die Laufrille bezogen auf die Längsachse der Eingabevorrichtung in Umfangsrichtung eine konkave, kreisbogenförmige Flächenkontur und in axialer Richtung einen wellenförmige Flächenkontur aufweist mit in axialer Richtung aufeinander folgenden Erhöhungen und Rastvertiefungen, an denen der Rastkopf beim Verschieben des Tastenkopfes mit linienförmigem Kontakt entlang gleitet und dadurch den Benutzer beim Betätigen des Tastenkopfes eine taktile Rückmeldung über das Erreichen vorgegebener Hubstellungen bereitstellt. It can be provided, for example, that the locking head is designed spherical and the running groove with respect to the longitudinal axis of the input device in the circumferential direction a concave, circular arc-shaped surface contour and in axial direction has a wavy surface contour with successive in the axial direction increases and locking recesses on which the locking head slides when moving the key head with linear contact along, thereby providing the user when pressing the key head tactile feedback on the achievement of predetermined stroke positions.
Bei einer vorteilhaften Ausführungsform der Erfindung weist die Eingabevorrichtung ein Rastglied auf, das starr mit dem Tastenkopf verbunden ist und das mindestens eine Laufrille aufweist, die einem Rastelement zugeordnet ist und zumindest eine Rastvertiefung aufweist. Das Rastglied kann zusammen mit dem Tastenkopf in axialer Richtung bewegt werden. Es kann eine oder auch mehrere Laufrillen aufweisen, die jeweils einem in axialer Richtung unverschiebbar gehaltenen Rastelement zugeordnet sind, dessen Rastkopf unabhängig von der Hubstellung des Tastenkopfs permanent in die Laufrille eintaucht. In an advantageous embodiment of the invention, the input device on a locking member which is rigidly connected to the key top and which has at least one raceway, which is associated with a latching element and has at least one latching recess. The locking member can be moved together with the key head in the axial direction. It may have one or more grooves, which are each associated with a non-displaceably held in the axial direction latching element, the locking head permanently immersed in the groove regardless of the stroke position of the key top.
Es kann vorgesehen sein, dass das Rastglied als Rasthülse ausgestaltet ist, deren Längsachse koaxial zur Längsachse der Eingabevorrichtung ausgerichtet ist und die auf ihrer Außenseite mindestens eine Laufrille mit mindestens einer Rastvertiefung trägt und die starr mit einem Stößel verbunden ist, der wiederum starr mit dem Tastenkopf verbunden ist. Eine Betätigung des Tastenkopfs führt somit zu einer linearen Bewegung des Stößels und der Rasthülse, und bei Erreichen von mindestens einer vorgegebenen Hubstellung des Tastenkopfes taucht ein Rastkopf in eine Rastvertiefung ein. It can be provided that the locking member is designed as a detent sleeve whose longitudinal axis is aligned coaxially to the longitudinal axis of the input device and carries on its outer side at least one raceway groove with at least one detent recess and which is rigidly connected to a plunger, which in turn is rigidly connected to the key top connected is. An actuation of the key head thus leads to a linear movement of the plunger and the detent sleeve, and upon reaching at least one predetermined stroke position of the key top a detent head dives into a detent recess.
Günstigerweise umfasst die Eingabevorrichtung zwei einander diametral gegenüberliegende Rastelemente, die fluchtend zueinander ausgerichtet sind und deren Rastköpfe mittels Rückstellfedern radial in Richtung auf die Längsachse der Eingabevorrichtung vorgespannt sind. Die beiden Rastköpfe können ein starr mit dem Tastenkopf verbundenes Rastglied zwischen sich aufnehmen, das an seiner Außenseite zwei Laufrillen aufweist, in die jeweils ein Rastkopf eintaucht. Die nachfolgende Beschreibung einer vorteilhaften Ausführungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung . Es zeigen : Conveniently, the input device comprises two diametrically opposed latching elements, which are aligned with each other and whose latching heads are biased by means of return springs radially in the direction of the longitudinal axis of the input device. The two locking heads can accommodate a rigidly connected to the key top locking member between them, which has two grooves on its outer side, in each of which a locking head dips.

Zur Eingabe eines Steuerbefehls weist die Eingabevorrichtung 22 einen flachen Tastenkopf 58 auf, der auf dem Deckelteil 36 aufsitzt. An den Tastenkopf 60 schließt sich starr ein Stößel 62 an, der koaxial zu einer Längsachse 64 der Eingabevorrichtung 22 ausgerichtet ist und mit einem der Bodenwand 34 zugewandten unteren Endabschnitt 66 die zentrale Wandöffnung 54 der Zwischenwand 48 durchgreift. Am unteren Endabschnitt 66 des Stößels 62 ist ein Mitnehmer 68 angeordnet, der in Form eines senkrecht zur Längsachse 64 ausgerichteten Mitnahmestiftes 70 ausgestaltet ist und den unteren Endabschnitt 66 diametral durchgreift. Die aus dem unteren Endabschnitt 66 in radialer Richtung herausragenden Endbereiche 71, 73 des Mitnahmestifts 70 tauchen jeweils in einen kurvenförmigen Führungsschlitz 72, 74 eines hülsen- förmigen Drehgliedes 76 ein, das sich von der Zwischenwand 48 in Richtung der Bodenwand 34 erstreckt. For inputting a control command, the input device 22 has a flat key top 58, which is seated on the cover part 36. To the key top 60 A plunger 62 connects rigidly, which is aligned coaxially to a longitudinal axis 64 of the input device 22 and with a bottom wall 34 facing the lower end portion 66, the central wall opening 54 of the intermediate wall 48 passes through.

Bezogen auf die Längsachse 64 ist das Drehglied 76 axial unbeweglich an der Führungshülse 50 gehalten. Zu diesem Zweck weist das Drehglied 76 axial und in Umfangsrichtung versetzt zu den Führungsschlitzen 72, 74 zwei Halteschlitze 75, 77 auf, die sich bezogen auf die Längsachse 64 in Umfangsrichtung erstrecken und in die jeweils ein ortsfest an der Führungshülse 50 gehaltener Haltestift 79, 81 eintaucht. Relative to the longitudinal axis 64, the rotary member 76 is held axially immovably on the guide sleeve 50. For this purpose, the rotary member 76 axially and in the circumferential direction offset from the guide slots 72, 74, two retaining slots 75, 77 which extend relative to the longitudinal axis 64 in the circumferential direction and in each of which a stationary held on the guide sleeve 50 retaining pin 79, 81 dips.
Der Bodenwand 34 zugewandt weist das Drehglied 76 eine kreiszylindrische Aufnahme 78 auf, in der ein lateral, das heißt quer zur Längsachse 64 polarisierter zylindrischer Permanentmagnet 80 drehfest gehalten ist. Dem Permanentmagnet 80 ist ein magnetfeldempfindliches Sensorelement 82 zugeordnet, das unterhalb der Bodenwand 34 auf einer im Gehäuse 12 positionierten Leiterplatte 84 angeordnet ist und über an sich bekannte und deshalb zur Erzielung einer besseren Übersicht in der Zeichnung nicht dargestellte elektrische Verbindungsleitungen mit der in der Zeichnung nicht dargestellten Steuer- und Übertragungselektronik des Bediengeräts 10 in elektrischer Verbindung steht. Facing the bottom wall 34, the rotary member 76 a circular cylindrical receptacle 78, in which a laterally, that is transversely to the longitudinal axis 64 polarized cylindrical permanent magnet 80 is rotatably held. The permanent magnet 80 is associated with a magnetic field sensitive sensor element 82 which is disposed below the bottom wall 34 on a positioned in the housing 12 printed circuit board 84 and not known per se and therefore to achieve a better overview in the drawing electrical connection lines with the in the drawing shown control and transmission electronics of the HMI device 10 is in electrical connection.
An einem oberen Endabschnitt 86 des Stößels 62 ist ein Rastglied 88 festgelegt, das im dargestellten Ausführungsbeispiel als zylindrische Rasthülse 90 ausgebildet ist. Die Rasthülse 90 wird in Längsrichtung vom Stößel 62 durchgriffen. Der Stößel 62 ist von einer schraubenförmigen Rückstellfeder 92 um- geben, die sich einerseits an einem radial nach innen gerichteten Bund 94 der Rasthülse 90 und andererseits an der Zwischenwand 48 abstützt. At an upper end portion 86 of the plunger 62, a locking member 88 is fixed, which is formed in the illustrated embodiment as a cylindrical locking sleeve 90. The latching sleeve 90 is penetrated in the longitudinal direction by the plunger 62. The plunger 62 is surrounded by a helical return spring 92. which is supported on the one hand on a radially inwardly directed collar 94 of the latching sleeve 90 and on the other hand on the intermediate wall 48.
Wie bereits erwähnt, bildet die Eingabevorrichtung 22 eine vormontierbare Baueinheit aus, die in der Montagerichtung 24 in die Vertiefung 26 eingesetzt werden kann. Zur Festlegung der Eingabevorrichtung 22 in der Vertiefung 26 kommt das Verbindungselement 20 zum Einsatz, das im dargestellten Ausführungsbeispiel in Form eines Überwurfringes 96 ausgestaltet ist. Der Überwurfring 96 umgibt das Deckelteil 36 und den Tastenkopf 60 in Umfangsrich- tung und weist ein Außengewinde 98 auf, das in ein komplementär ausgestaltetes Innengewinde 100 eingeschraubt werden, das am oberen Seitenwand- abschnitt 28 der Vertiefung 26 angeordnet ist. As already mentioned, the input device 22 forms a preassemblable unit that can be inserted into the recess 26 in the mounting direction 24. To fix the input device 22 in the recess 26, the connecting element 20 is used, which is designed in the illustrated embodiment in the form of a coupling ring 96. The coupling ring 96 surrounds the cover part 36 and the key head 60 in the circumferential direction and has an external thread 98, which are screwed into a complementarily designed internal thread 100, which is arranged on the upper side wall section 28 of the recess 26.
Zur stufenlosen Befehlseingabe kann der Benutzer den Tastenkopf 60 betätigen, so dass dieser zusammen mit dem Stößel 62 und der Rasthülse 90 unter elastischer Verformung des Deckelteils 36 entgegen der Rückstell kraft der Rückstellfeder 92 entlang der Längsachse 64 linear verschoben wird . Die lineare Bewegung des Stößels 62 wird über den Mitnehmer 68 und die kurvenförmigen, sich in axialer Richtung und in Umfangsrichtung erstreckenden Führungsschlitze 72, 74 in eine rotatorische Bewegung des Drehgliedes 76 und des an ihm festgelegten Permanentmagneten 80 übertragen. Die Drehachse des Drehglieds 76 stimmt mit der Längsachse 64 der Eingabevorrichtung 22 überein. Eine Betätigung des Tastenkopfes 60 hat eine Änderung der Drehstellung des Permanentmagneten 80 zur Folge. Der Permanentmagnet 80 ist quer zur Längsachse 64 magnetisiert, so dass eine Änderung der Drehstellung des Permanentmagneten 80 eine Änderung der Ausrichtung des von ihm erzeugten Magnetfeldes relativ zur Längsachse 64 zur Folge hat. Das Magnetfeld durchgreift die Bodenwand 34, so dass dessen Ausrichtung innerhalb des Gehäuses 12 vom Sensorelement 82 erfasst werden kann. Die durch die Hubbewegung des Tastenkopfs 58 verursachte Änderung der Drehstellung des Permanentmagneten 80 wird somit vom magnetfeldempfindlichen Sensorelement 82 erfasst, das daraufhin der Steuer- und Übertragungselektronik ein von der Drehstellung des Permanentmagneten 80 abhängiges Sensorsignal bereitstellt. Die Steuer- und Übertragungselektronik generiert ein entsprechendes Steuersignal, das an das zu steuernde Gerät übertragen wird . For stepless command input, the user can press the key top 60 so that it is linearly displaced along the longitudinal axis 64 together with the plunger 62 and the locking sleeve 90 under elastic deformation of the cover member 36 against the restoring force of the return spring 92. The linear movement of the plunger 62 is transmitted via the driver 68 and the curved, axially and circumferentially extending guide slots 72, 74 in a rotational movement of the rotary member 76 and the permanent magnet 80 fixed to it. The axis of rotation of the rotary member 76 coincides with the longitudinal axis 64 of the input device 22. An actuation of the key top 60 has a change in the rotational position of the permanent magnet 80 result. The permanent magnet 80 is magnetized transversely to the longitudinal axis 64, so that a change in the rotational position of the permanent magnet 80 results in a change in the orientation of the magnetic field generated by it relative to the longitudinal axis 64 result. The magnetic field passes through the bottom wall 34, so that its orientation within the housing 12 can be detected by the sensor element 82. The change in the rotational position of the permanent magnet 80 caused by the lifting movement of the key head 58 is thus detected by the magnetic-field-sensitive sensor element 82, which then the control and transmission electronics a depending on the rotational position of the permanent magnet 80 sensor signal provides. The control and transmission electronics generates a corresponding control signal, which is transmitted to the device to be controlled.
Um dem Benutzer eine taktile Rückmeldung über das Erreichen vorgegebener Hubstellungen des Tastenkopfs 58 bereitzustellen, weist die Eingabevorrichtung 22 zwei einander diametral gegenüberliegende Rastelemente 102, 104 auf, die am Halteteil 56 gehalten sind und jeweils einen kugelförmigen Rastkopf 106 aufweisen, der mittels einer Rastfeder 108 bezogen auf die Längsachse 64 radial nach innen vorgespannt ist. Den Rastelementen 102, 104 sind jeweils drei Rastvertiefungen 110, 112, 114 zugeordnet, die an der Außenseite der Rasthülse 90 in axialer Richtung in Reihe hintereinander angeordnet sind. Wird der Stößel 62 durch Betätigung des Tastenkopfes 58 linear bewegt, so tauchen die Rastköpfe 106 in bestimmten Hubstellungen, die durch die Lage der Rastvertiefungen 110, 112, 114 vorgegeben sind, in eine der Rastvertiefungen 110, 112, 114 ein und geben dadurch dem Benutzer eine taktile Rückmeldung über das Erreichen der jeweiligen Hubstellung. In order to provide the user with a tactile feedback on the achievement of predetermined stroke positions of the key top 58, the input device 22 has two diametrically opposed locking elements 102, 104, which are held on the holding part 56 and each having a spherical locking head 106, which by means of a detent spring 108 related is biased on the longitudinal axis 64 radially inwardly. The latching elements 102, 104 are each associated with three latching recesses 110, 112, 114, which are arranged on the outside of the latching sleeve 90 in the axial direction in series one behind the other. If the plunger 62 is moved linearly by actuation of the key head 58, the latching heads 106 in certain stroke positions, which are predetermined by the position of the latching recesses 110, 112, 114, dip into one of the latching recesses 110, 112, 114 and thereby give the user a tactile feedback on reaching the respective stroke position.
Wie insbesondere aus den Figuren 5 und 6 deutlich wird, sind die jeweils einem Rastelement 102, 104 zugeordneten Rastvertiefungen 110, 112, 114 in eine Laufrille 116 eingeformt, die sich in axialer Richtung entlang der Außenseite der Rasthülse 90 erstreckt. Die Form der Laufrille 116 ist ebenso wie die Form der Rastelemente 110, 112, 114 an die Kugelform des jeweils eintauchenden Rastkopfes 106 angepasst. Bezogen auf die Längsachse 64 der Eingabevorrichtung 22 weist die Laufrille 116 in Umfangsrichtung eine konkave, kreisbogenförmige und in axialer Richtung einen wellenförmige Flächenkontur auf mit in axialer Richtung aufeinander folgenden Erhöhungen und Rastvertiefungen, an denen der Rastkopf 106 beim Bewegen des Tastenkopfes 58 mit linienförmigem Kontakt entlanggleitet und dadurch den Benutzer beim Betätigen des Tastenkopfes 58 eine taktile Rückmeldung über das Erreichen vorgegebener Hubstellungen bereitstellt. Durch die Anpassung der Form der Laufrille 116 und der Rastvertiefungen 110, 112, 114 an die Form des Rastkopfes 106 wird eine punktförmige Belastung sowohl der Laufrille 116 als auch der Rastvertiefungen 110, 112, 114 durch den Rastkopf 106 vermieden. Die Montage der Bedienungseinrichtungen 18 gestaltet sich sehr einfach. Wie bereits erwähnt, kann die jeweilige Eingabevorrichtung 22 als vormontierte Baueinheit in der Montagerichtung 24 in eine der Vertiefungen 26 eingesetzt werden. Anschließend kann ein Überwurfring 96 auf die Eingabevorrichtung 22 aufgesetzt und mit dem Gehäuse 12 verschraubt werden. Zur Montage der Bedienungseinrichtungen 18 ist es somit nicht erforderlich, das Gehäuse 12 zu öffnen. Sollen eine oder mehrere Eingabevorrichtungen 22 zu einem späteren Zeitpunkt ausgetauscht werden, so kann auch der Austausch erfolgen, ohne dass das Gehäuse 12 geöffnet werden muss. Es ist lediglich erforderlich, die Schraubverbindung des Überwurfringes 96 zu lösen, und anschließend kann die jeweilige Eingabevorrichtung 22 auf einfache Weise der Vertiefung 26 entnommen werden. As is clear in particular from FIGS. 5 and 6, the latching recesses 110, 112, 114 assigned to each latching element 102, 104 are formed in a raceway groove 116 which extends in the axial direction along the outside of the latching sleeve 90. The shape of the raceway 116 as well as the shape of the locking elements 110, 112, 114 adapted to the spherical shape of each dipping locking head 106. Relative to the longitudinal axis 64 of the input device 22, the track groove 116 in the circumferential direction has a concave, circular arc and in the axial direction a wavy surface contour with successive successive elevations and detent recesses in the axial direction along which the locking head 106 slides when moving the key top 58 with linear contact and thereby provides the user upon actuation of the key top 58 a tactile feedback on the achievement of predetermined stroke positions. By adapting the shape of the raceway groove 116 and the locking recesses 110, 112, 114 to the shape of the locking head 106, a punctiform loading of both the raceway 116 and the locking recesses 110, 112, 114 is avoided by the locking head 106. The installation of the controls 18 is very simple. As already mentioned, the respective input device 22 can be used as a preassembled structural unit in the mounting direction 24 in one of the depressions 26. Subsequently, a coupling ring 96 can be placed on the input device 22 and screwed to the housing 12. For mounting the operating devices 18, it is thus not necessary to open the housing 12. If one or more input devices 22 are to be replaced at a later time, then the replacement can also take place without the housing 12 having to be opened. It is only necessary to solve the screw connection of the coupling ring 96, and then the respective input device 22 can be easily removed from the recess 26.
