Description

Die Erfindung betrifft einen Drehgeber nach dem Oberbegriff des Patentanspruchs 1 sowie ein Gerät oder eine Gerätebaugruppe mit einem solchen Drehgeber.The invention relates to a rotary encoder according to the preamble of patent claim 1 and a device or a device assembly with such a rotary encoder.

Ein gattungsgemäßer Drehgeber ist aus der EP 1 278 111 A2 bekannt. Dort ist ein Bedienelement beschrieben, welches eine Haube, ein Kupplungselement und eine Auswerteeinheit aufweist. Die Haube ist über ein erstes Verbindungsstück mit dem Kupplungselement und dieses mit einem zweiten Verbindungsstück mit der Achse der Auswerteeinheit verbunden. Das Kupplungselement ist nun gegenüber beiden Verbindungsstücken verschiebbar ausgeführt, wobei die Verschieberichtungen senkrecht zueinander stehen. Die Haube des Bedienelements ist in einer Öffnung eines Gerätegehäuses geführt. Die Anordnung bewirkt, dass ein seitlicher Versatz der Achse der Auswerteeinheit gegenüber dem Zentrum der Gehäuseöffnung ausgeglichen wird. Sie hat jedoch den Nachteil, dass eine Vielzahl ineinander greifender Teile, die separat hergestellt und danach zusammengesetzt werden müssen, notwendig ist.A generic encoder is from the EP 1 278 111 A2 known. There, an operating element is described, which has a hood, a coupling element and an evaluation unit. The hood is connected via a first connecting piece with the coupling element and this with a second connecting piece with the axis of the evaluation unit. The coupling element is now designed to be displaceable relative to the two connecting pieces, wherein the displacement directions are perpendicular to one another. The hood of the control element is guided in an opening of a device housing. The arrangement has the effect that a lateral offset of the axis of the evaluation unit with respect to the center of the housing opening is compensated. However, it has the disadvantage that a plurality of interlocking parts, which must be manufactured separately and then assembled together, is necessary.

Somit stellt sich der Erfindung die Aufgabe, ausgehend von dem genannten Stand der Technik einen Drehgeber vorzuschlagen, welcher mit weniger Bauteilen gewährleistet, einen Axialversatz auszugleichen.Thus, the invention has the object, starting from the cited prior art to propose a rotary encoder, which ensures with fewer components to compensate for axial misalignment.

Diese Aufgabe wird durch einen Drehgeber mit den Merkmalen des Patentanspruchs 1 sowie ein Gerät oder eine Gerätebaugruppe gemäß Anspruch 10 gelöst. Die abhängigen Ansprüche 2 bis 9 beschreiben vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.This object is achieved by a rotary encoder with the features of patent claim 1 and a device or a device assembly according to claim 10. The dependent claims 2 to 9 describe advantageous embodiments and further developments of the invention.

Durch die erfindungsgemäße Bauart, dass nämlich die Achse des Drehschalters an ihrem Ende beidseitig abgeflacht ist und somit selbst in eine Führung in dem Kupplungselement eingreifen kann, werden statt fünf Teilen nur noch drei benötigt, was die Herstellung und die Montage des Drehgebers deutlich vereinfacht.Due to the design according to the invention, namely that the axis of the rotary switch is flattened on both sides at its end and thus can intervene even in a guide in the coupling element, only three are needed instead of five parts, which significantly simplifies the production and installation of the encoder.

Vorzugsweise weist das Kupplungselement auf seiner dem Drehschalter zugewandten Seite eine plane Anlagefläche auf, mit welcher es sich an einer ebenfalls planen Fläche (z.B. des Drehschalters oder einer den Drehschalter tragenden Leiterplatte) abstützt. Im Falle der Montage des Drehgebers auf bzw. an einer Leiterplatte kann der Drehschalter auf der Seite der Leiterplatte angeordnet und befestigt sein, die dem Betätigungskopf gegenüber liegt, und mit seiner Achse durch eine Bohrung in dieser Leiterplatte hindurchragen.The coupling element preferably has, on its side facing the rotary switch, a planar contact surface with which it is supported on a likewise plane surface (for example the rotary switch or a circuit board carrying the rotary switch). In the case of mounting the rotary encoder on or on a printed circuit board, the rotary switch can be arranged and fixed on the side of the printed circuit board, which lies opposite the actuating head, and project with its axis through a hole in this printed circuit board.

In Weiterbildung der Erfindung kann vorgesehen sein, dass der Betätigungskopf auf einer zweiten Achse gehaltert ist, wobei dann diese zweite Achse auf dem Kupplungselement verschiebbar gehaltert ist. In diesem Fall kann der Betätigungskopf auf der zweiten Achse auch axial verschiebbar gehaltert sein, wodurch z.B. ein versenkbarer Betätigungskopf realisiert werden kann.In a further development of the invention can be provided that the actuating head is mounted on a second axis, in which case this second axis is slidably supported on the coupling element. In this case, the actuating head on the second axis can also be held axially displaceable, whereby e.g. a retractable actuator head can be realized.

In bevorzugter Ausgestaltung der Erfindung weist das Kupplungselement auch auf seiner dem Betätigungskopf zugewandten Seite eine Führung auf, in welche der Betätigungskopf oder die dem Betätigungskopf tragende Achse verschiebbar eingreifen. Weiterhin kann das Kupplungselement einen Befestigungsabschnitt aufweisen, an dem der Betätigungsknopf bzw. die den Betätigungsknopf tragende Achse (vorzugsweise über Schnapphaken oder Hinterschneidungen) gehaltert ist.In a preferred embodiment of the invention, the coupling element on its side facing the actuating head on a guide, in which engage the actuating head or the actuating head bearing axis slidably. Furthermore, the coupling element may have a fastening portion, on which the actuating button or the axis carrying the actuating button (preferably via snap hooks or undercuts) is held.

Weiterhin kann ein Halteelement vorgesehen sein, welches das Kupplungselement auf der Achse des Drehschalters hält. Schließlich kann vorgesehen sein, dass ein Führungselement den Betätigungskopf oder auch die den Betätigungskopf tragende Achse führt, was auch bei einem axialen Versatz der Drehachsen möglich ist, ohne dass die Funktionalität des Drehgebers beeinträchtigt wird.Furthermore, a holding element may be provided which holds the coupling element on the axis of the rotary switch. Finally, it can be provided that a guide element guides the actuating head or the axis carrying the actuating head, which is also possible with an axial offset of the axes of rotation, without the functionality of the rotary encoder being impaired.

In the following an embodiment of the invention will be explained in more detail with reference to the drawings. Showing:

a section perpendicular to FIG. 1 and

the assembly of the rotary encoder.

Auf einer Leiterplatte 1 ist neben anderen elektrischen oder elektronischen Bauelementen ein Drehschalter 2 angeordnet. Dabei kann es sich um ein Potentiometer oder einen Drehstellungsgeber handeln. Die Achse 3 des Drehschalters 2 ragt durch eine Öffnung 4 in der Leiterplatte 1. Das Ende 5 der Achse 3 ist beidseitig abgeflacht. Auf das Ende 5 der Achse 3 ist ein Kupplungselement 6 formschlüssig aufgesteckt. Es stützt sich mit seiner planen Anlagefläche 24 gegen die Oberfläche 7 der Leiterplatte 1 ab und weist mittig eine Öffnung auf, die als Führung 8 für das seitlich abgeflachte Ende 5 der Achse 3 dient. In dieser Führung 8 ist das Ende 5 der Achse 3 in einer Richtung senkrecht zur Schnittfläche der Figur 1 verschiebbar (siehe Pfeil R1).On a printed circuit board 1, a rotary switch 2 is arranged in addition to other electrical or electronic components. This can be a potentiometer or a rotary position transmitter. The axis 3 of the rotary switch 2 protrudes through an opening 4 in the printed circuit board 1. The end 5 of the axis 3 is flattened on both sides. On the end 5 of the axis 3, a coupling element 6 is fitted positively. It is supported with its planar contact surface 24 against the surface 7 of the circuit board 1 and has an opening in the middle, which serves as a guide 8 for the laterally flattened end 5 of the axis 3. In this guide 8, the end 5 of the axis 3 in a direction perpendicular to the sectional surface of FIG. 1 displaceable (see arrow R1).

Des weiteren weist das Kupplungselement 6 Öffnungen 9 auf, in welche zwei, an gegenüberliegenden Seiten einer hohlen Achse 10 angeformte Beine 11 eingreifen. Die als Führungen dienenden Öffnungen 9 in dem Kupplungselement 6 sind derart ausgeformt, dass die hohle Achse 10 mit ihren Beinen in diesen entlang der Schnittebene verschiebbar ist (siehe Pfeil R2), während die hohle Achse 10 formschlüssig mit dem Kupplungselement 6 verbunden ist.Furthermore, the coupling element 6 openings 9, in which engage two, formed on opposite sides of a hollow axis 10 legs 11. The serving as guides openings 9 in the coupling element 6 are formed such that the hollow axis 10 with its legs in these along the cutting plane is displaceable (see arrow R2), while the hollow axis 10 is positively connected to the coupling element 6.

Auf der hohlen Achse 10 ist ein Betätigungskopf 12 gehaltert. Diese Halterung ist derart ausgebildet, dass der Betätigungskopf 12 in axialer Richtung auf die hohle Achse 10 aufgeschoben werden kann. Im Inneren des hohlen Betätigungskopfes 12 und der hohlen Achse 10 ist eine Mechanik 13, 14, 15 mit einer Feder 16 angeordnet, die nach dem Kugelschreiber-Prinzip arbeitet und es ermöglicht, dass der Betätigungskopf 12 durch Druck in axialer Richtung auf die hohle Achse 10 aufgeschoben werden kann und in einer aufgeschobenen Position gehalten wird, durch erneuten Druck in axialer Richtung wieder entriegelt und in die in den Figuren 1 und 2 gezeigte ausgefahrene Position zurückgebracht werden kann. Auf diese Weise ist ein versenkbarer Drehknopf geschaffen, dessen Betätigungskopf 12 bei Nichtgebrauch in eine (z.B. in einer Bohrung in einer nicht gezeigten Gehäuseblende) versenkte Position bringbar ist.On the hollow axis 10, an actuating head 12 is supported. This holder is designed such that the actuating head 12 can be pushed onto the hollow axis 10 in the axial direction. Inside the hollow actuating head 12 and the hollow shaft 10, a mechanism 13, 14, 15 is arranged with a spring 16, which operates on the ballpoint pen principle and allows the actuating head 12 by pressure in the axial direction on the hollow axis 10th can be pushed and held in a deferred position, unlocked by renewed pressure in the axial direction and in the in the characters 1 and 2 shown extended position can be returned. In this way, a retractable knob is provided, the actuating head 12 when not in use in a (eg in a hole in a housing cover not shown) recessed position can be brought.

Der Schnitt durch den Drehgeber in Figur 2 ist senkrecht zu dem in Figur 1. Somit liegt die Verschieberichtung R1, in welcher das Kupplungselement 6 gegenüber der Achse 3 des Drehschalters 2 in der Führung 8 verschiebbar ist, in der Schnittebene. Dagegen liegt die Verschieberichtung R2, in welcher der Betätigungskopf 12 mit der hohlen Achse 10 gegenüber dem Kupplungselement 6 in der (in Figur 2 nicht sichtbaren) Führung 9 verschiebbar ist, senkrecht zur Schnittebene.The section through the encoder in FIG. 2 is perpendicular to the in FIG. 1 , Thus, the displacement direction R1, in which the coupling element 6 relative to the axis 3 of the rotary switch 2 in the guide 8 is displaceable, in the cutting plane. In contrast, the displacement direction R2, in which the actuating head 12 with the hollow axis 10 relative to the coupling element 6 in the (in FIG. 2 not visible) guide 9 is displaceable, perpendicular to the cutting plane.

Die beiden rechtwinklig zueinander angeordneten Verschieberichtungen R1 und R2 ermöglichen somit in ihrer Kombination der Bewegungen, einen axialen Versatz beim Drehen des Betätigungskopfes 12 auszugleichen.The two directions of rotation R1 and R2 arranged at right angles to one another thus make it possible, in their combination of the movements, to compensate for an axial offset when the actuating head 12 is rotated.

In den Figuren 3a und 3b ist der Zusammenbau des Drehgebers gezeigt. Dabei wird das Kupplungselement 6 auf das seitlich abgeflachte Ende 5 der Achse 3 des Drehschalters 2 aufsteckt (Figur 3a). Danach wird der Betätigungskopf 12 mit der hohlen Achse 10 so auf das Kupplungselement aufgesteckt, dass die Füße 11 der hohlen Achse 10 in die Führungen 9 im Kupplungselement 6 eingreifen.In the FIGS. 3a and 3b the assembly of the encoder is shown. In this case, the coupling element 6 is attached to the laterally flattened end 5 of the axis 3 of the rotary switch 2 ( FIG. 3a ). Thereafter, the actuating head 12 is fitted with the hollow shaft 10 on the coupling element, that the feet 11 of the hollow shaft 10 engage in the guides 9 in the coupling element 6.

Das Kupplungselement 6 besitzt einen Aufbau 17, der beidseitig mit angeformten Schrägen 18 mit Hinterschneidungen ausgestattet ist, hinter welche innerhalb der hohlen Achse 10 angeordnete und an dieser angeformte Befestigungselemente 19 beim Aufstecken des Betätigungskopfes 12 mit der hohlen Achse 10 auf das Kupplungselement 6 einschnappen. Auf diese Weise ist der Betätigungskopf 12 mit der hohlen Achse 10 fest (aber entlang der Richtung R2 verschiebbar) mit dem Kupplungselement 6 verbunden und kann nur unter erhöhtem Kraftaufwand (oder ohne eine Zerstörung des Drehgebers gar nicht) wieder abgezogen werden.The coupling element 6 has a structure 17, which is provided on both sides with integrally formed bevels 18 with undercuts behind which are arranged within the hollow shaft 10 and integrally formed thereon fasteners 19 when plugging the actuating head 12 with the hollow shaft 10 on the coupling element 6. In this way, the actuating head 12 with the hollow shaft 10 is fixed (but displaceable along the direction R2) connected to the coupling element 6 and can be withdrawn only under increased force (or not at all a destruction of the encoder) again.

Die feste Verbindung des Kupplungselements 6 mit der Achse 3 des Drehschalters 2 erfolgt mittels eines Gehäuses 20, in dem die Leiterplatte 1 gehaltert ist, das eine Öffnung 21 für den Durchtritt der hohlen Achse 10 bzw. des Betätigungskopfes 12 mit einer Wand 22 und einem an der Wand 22 angeformten Haltering 23 aufweist, welcher das Kupplungselement 6 gegen die Oberfläche 7 der Leiterplatte 1 drückt und somit fest auf der Achse 3 des Drehschalters 2 hält.The fixed connection of the coupling element 6 with the axis 3 of the rotary switch 2 by means of a housing 20 in which the circuit board 1 is supported, which has an opening 21 for the passage of the hollow shaft 10 and the actuating head 12 having a wall 22 and an integrally formed on the wall 22 retaining ring 23 which presses the coupling element 6 against the surface 7 of the circuit board 1 and thus holds firmly on the axis 3 of the rotary switch 2.

Der beschriebene Drehgeber stellt ein einfach und mit wenigen Teilen aufgebautes Drehbetätigungselement mit einem versenkbaren Kopf dar, der durch Anwendung des an sich bekannten Prinzips der Kardanwelle einen Axialversatz ausgleichen kann.The rotary encoder described is a simple and constructed with few parts rotary actuator with a retractable head, which can compensate for axial misalignment by applying the known principle of the cardan shaft.

Der Drehgeber kann nachträglich montiert werden, d.h. der Betätigungskopf 12 mit der hohlen Achse 10 kann auch erst nach erfolgter Montage der Leiterplatte 1 in dem Schaltuhrgehäuse 2 und sogar erst nach der Montage der gesamten Schaltuhr im Kochherd (also nach Anbringen einer Bedienblende vor der Vorderseite des Schaltuhrgehäuses 20) montiert werden, indem er durch eine Öffnung in der Bedienblende und/oder durch die Öffnung 21 im Schaltuhrgehäuse 20 hindurch auf das vormontierte Kupplungselement 6 aufgesteckt wird.The encoder can be retrofitted, i. the actuator head 12 with the hollow shaft 10 can also be mounted only after the assembly of the circuit board 1 in the time switch housing 2 and even after the installation of the entire timer in the stove (ie after attaching a control panel in front of the timer housing 20) by is plugged through an opening in the control panel and / or through the opening 21 in the timer housing 20 through the preassembled coupling element 6.

Durch den Aufbau 17 des Kupplungselements 6 kann zudem nach erfolgter Montage des Drehschalters 2 auf der Leiterplatte 1, des Kupplungselements 6 auf der Achse 3 des Drehschalters 2 und der Leiterplatte 1 mit Drehschalter 2 und Kupplungselement 6 in dem Gehäuse 20 die Funktion des Drehschalters 2 getestet werden, indem eine Person das Kupplungselement 6 am Aufbau 17 anfasst und so den Drehschalter 2 betätigt.Due to the structure 17 of the coupling element 6 can also after the installation of the rotary switch 2 on the circuit board 1, the coupling element 6 on the axis 3 of the rotary switch 2 and the circuit board 1 with rotary switch 2 and coupling element 6 in the housing 20, the function of the rotary switch 2 tested be touched by a person, the coupling element 6 on the structure 17 and so the rotary switch 2 is actuated.

Ein weiterer Vorteil des beschriebenen Drehgebers liegt darin, dass Druckkräfte nicht auf die Achse 3 des Drehschalters 2 weitergegeben werden, sondern über das sich auf der Oberfläche 7 der Leiterplatte 1 abstützende Kupplungselement 6 auf die Leiterplatte 1. Zugkräfte werden über die Befestigungselemente 19 der hohlen Achse 10, die Hinterschneidungen der Schrägen 18 am Aufbau 17 des Kupplungselements 6 und den Haltering 23 an der Öffnungsbegrenzungswand 22 auf das Gehäuse 20 übertragen.Another advantage of the rotary encoder described is that pressure forces are not transmitted to the axis 3 of the rotary switch 2, but via the on the surface 7 of the circuit board 1 supporting coupling element 6 on the circuit board 1. tensile forces are on the fasteners 19 of the hollow axis 10, the undercuts of the bevels 18 on the structure 17 of the coupling element 6 and the retaining ring 23 transmitted to the opening limiting wall 22 on the housing 20.

Es sei noch bemerkt, dass der Aufbau 17 des Kupplungselements 6 derart ausgeführt ist, dass seine Form der Achse von Standarddrehschaltern insoweit entspricht, dass vorhandene herkömmliche Prüfadapter zum Testen des Drehschalters verwendet werden können.It should also be noted that the structure 17 of the coupling element 6 is designed such that its shape corresponds to the axis of standard rotary switches insofar, Existing conventional test adapters can be used to test the rotary switch.
