Description

Antrieb für ein bewegbares Möbelteil Drive for a movable furniture part
Die vorliegende Erfindung betrifft einen Antrieb für ein bewegbares Möbelteil, mit einem Elektromotor, der als Linearmotor ausgebildet ist und einen Stator und einen Läufer aufweist, wobei der Läufer entlang einer gedachten Geraden verschiebbar ist und wobei Stator und Läufer zueinander mit einem Spiel gelagert sind, das eine zumindest teilweise Kompensation einer Veränderung der relativen Lage zwischen Stator und Läufer quer zur gedachten Geraden gestattet.The present invention relates to a drive for a movable furniture part, with an electric motor which is designed as a linear motor and having a stator and a rotor, wherein the rotor is displaceable along an imaginary straight line and wherein stator and rotor are mounted to each other with a game, the allows at least partial compensation of a change in the relative position between the stator and rotor transversely to the imaginary line.
Um eine möglichst hohe Effizienz zu erreichen, müssen Stator und Läufer über den angetriebenen Teil des Verschiebeweges des Läufers entlang der gedachten Geraden möglichst nahe beieinander angeordnet sein. Dies bedeutet aber, dass es bereits bei einer geringfügigen Veränderung der relativen Lage zwischen Stator und Läufer zu einer ungewollten Kontaktierung von Stator und Läufer kommen kann, was die Funktionsfähigkeit des Antriebs beeinträchtigt.In order to achieve the highest possible efficiency, the stator and rotor must be arranged as close as possible to each other via the driven part of the displacement path of the rotor along the imaginary straight line. However, this means that even with a slight change in the relative position between stator and rotor, an undesired contacting of stator and rotor can occur, which impairs the functioning of the drive.
Eine derartige ungewollte Veränderung der relativen Lage kann beispielsweise in Folge von statischen Belastungen oder auch von dynamischen Belastungen des Antriebs während des Betriebs erfolgen.Such an unwanted change in the relative position can be done, for example, as a result of static loads or even dynamic loads of the drive during operation.
Besonders schwerwiegend stellt sich die Situation dar, wenn das bewegbare Möbelteil als Schublade ausgebildet ist. In diesem Fall ist es aus Platzgründen günstig, den Antrieb in die Schubladenausziehführung zu integrieren. Aufgrund des sich verändernden Beladungszustandes der Schublade variiert allerdings die auf die Schubladenausziehführung durch die Schublade aufgebrachte Last. Dadurch ändern sich auch die Deformationen der Schienen der Schubladenausziehführung und damit die relative Lage zwischen Stator und Läufer des Antriebs.The situation is particularly serious when the movable furniture part is designed as a drawer. In this case, it is convenient for reasons of space to integrate the drive in the drawer extension. However, due to the changing loading state of the drawer, the load applied to the drawer extension guide by the drawer varies. This also changes the deformations of the rails of the drawer extension guide and thus the relative position between the stator and rotor of the drive.
Aus der AT 398 513 B geht ein gattungsgemäßer Antrieb hervor.The AT 398 513 B shows a generic drive.
Aufgabe der Erfindung ist es, einen gattungsgemäßen Antrieb derart weiterzubilden, dass die oben genannten Probleme behoben werden. Diese Aufgabe wird durch einen Antrieb mit den Merkmalen des Anspruchs 1 gelöst. Dadurch, dass die relative Lagerung von Stator und Läufer um eine Drehachse mit einem Spiel versehen ist, kann eine durch äußere Kräfte verursachte Veränderung der relativen Lage automatisch durch eine entsprechende Gegenbewegung im Rahmen des Spiels zumindest so weit kompensiert werden, dass eine ungewollte Kontaktierung von Stator und Läufer vermieden wird.The object of the invention is to develop a generic drive such that the above problems are resolved. This object is achieved by a drive with the features of claim 1. Characterized in that the relative bearing of the stator and rotor is provided around a rotation axis with a game, caused by external forces change in the relative position can be compensated automatically by a corresponding counter-movement in the context of the game at least so far that an unwanted contacting of stator and runners is avoided.
Weitere vorteilhafte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen definiert.Further advantageous embodiments of the invention are defined in the dependent claims.
Schutz wird auch begehrt für eine Schubladenausziehführung mit wenigstens zwei zueinander verschiebbaren Schienen, welche durch einen Antrieb nach einer der vorgenannten Ausführungsformen gekennzeichnet ist.Protection is also desired for a drawer extension with at least two mutually displaceable rails, which is characterized by a drive according to one of the aforementioned embodiments.
In diesem Fall kann das Spiel auf einfache Weise dadurch realisiert werden, dass der Stator an einer Korpusschiene der Schubladenausziehführung begrenzt bewegbar gelagert ist. In diesem Fall kann der Läufer starr mit einer Ladenschiene oder einer Mittelschiene der Schubladenausziehführung verbunden sein.In this case, the game can be realized in a simple manner by the fact that the stator is mounted movably limited to a carcass rail of the drawer extension. In this case, the runner may be rigidly connected to a drawer rail or a center rail of the drawer extension guide.

Fig. 6 eine Darstellung des Kraftverlaufs bei einer relativen Verdrehung von Stator und Läufer. Fig. 1 zeigt eine perspektivische Ansicht eines Teils einer Schubladenausziehführung mit einer an einem nicht dargestellten Möbelkorpus zu befestigenden Korpusschiene 6 sowie einer an einer nicht dargestellten Schublade zu befestigenden Ladenschiene 7. An der Korpusschiene 6 ist der Stator 1 eines als Linearmotor ausgebildeten Elektromotors befestigt. Wie insbesondere aus Fig. 5 hervorgeht, weist der Stator 1 in diesem Ausführungsbeispiel sechs Spulen auf, welche durch nicht dargestellte elektrische Leitungen mit Strom versorgt werden können.Fig. 6 is a representation of the force curve at a relative rotation of the stator and rotor. 1 shows a perspective view of a part of a drawer pull-out guide with a cabinet rail 6 to be fastened to a furniture unit, not shown, and a drawer rail 7 to be fastened to a drawer (not shown). The stator 1 of a motor designed as a linear motor is attached to the cabinet rail 6. As can be seen in particular from FIG. 5, the stator 1 in this exemplary embodiment has six coils which can be supplied with power by electrical lines, not shown.
In diesem Ausführungsbeispiel besteht der Läufer 2 aus zwei Permanentmagneten, welche an der Ladenschiene 7 befestigt sind. Bei einer Aktivierung des Elektromotors werden die Spulen des Stators 1 vom Strom durchflössen und erzeugen dabei einIn this embodiment, the rotor 2 consists of two permanent magnets, which are fixed to the drawer rail 7. Upon activation of the electric motor, the coils of the stator 1 are flowed through by the current and generate thereby
Magnetfeld, welches mit dem Magnetfeld des Läufers 2 zusammenwirkt und eineMagnetic field, which cooperates with the magnetic field of the rotor 2 and a
Bewegung der Ladenschiene 7 entlang der gedachten Linie 3 bewirkt. Durch unterschiedliche Schaltung des elektrischen Stroms kann eine Hinaus- bzw. eine Hineinbewegung der Ladenschiene 7 in den nicht dargestellten Möbelkorpus erfolgen.Movement of the drawer rail 7 along the imaginary line 3 causes. By different circuit of the electrical current can be carried out in the furniture body, not shown, an outward or inward movement of the drawer rail 7.
Die Fig. 1 und 2 zeigen eine Ideallage (Nullposition) des Stators 1 und des Rotors 2 relativ zueinander. In der Praxis kommt es allerdings häufig durch statische oder dynamische Belastungen zu einer Änderung der relativen Lage von Stator 1 und Läufer 2.Figs. 1 and 2 show an ideal position (zero position) of the stator 1 and the rotor 2 relative to each other. In practice, however, static or dynamic loads often result in a change in the relative position of stator 1 and rotor 2.
Beispielsweise ist in Fig. 3 die Situation dargestellt, dass sich die Ladenschiene 7 und dadurch der Läufer 2 seitlich in Bezug auf die Korpusschiene 6 verschoben haben. Wäre kein erfindungsgemäßes Spiel vorgesehen, würde dies dazu führen, dass sich der Läufer 2 und der Stator 1 kontaktieren, was die Funktionsfähigkeit des Elektromotors beeinträchtigen würde.For example, in Fig. 3, the situation is shown that the drawer rail 7 and thereby the rotor 2 have moved laterally with respect to the carcass rail 6. If no inventive game provided, this would cause the rotor 2 and the stator 1 contact, which would affect the functioning of the electric motor.
Erfindungsgemäß ist allerdings der Stator 1 in diesem Ausführungsbeispiel über ein Lagerteil 8 und ein Filmscharnier 9 derart mit der Korpusschiene 6 verbunden, dass die relative Verschiebung des Läufers 2 zum Stator 1 zumindest in einem solchen Ausmaß kompensiert werden kann, dass es zu keiner Kontaktierung des Läufers 2 und des Stators 1 kommt (siehe Vergrößerung A)According to the invention, however, the stator 1 is connected in this embodiment via a bearing part 8 and a film hinge 9 with the carcass rail 6 that the relative displacement of the rotor 2 to the stator 1 can be compensated for at least to such an extent that there is no contact of the rotor 2 and the stator 1 comes (see enlargement A)
Die sich verschiebende Ladenschiene 7 kommt dabei in Berührung mit einem mechanischen Anschlag 5, welcher an der Oberseite des Stators 1 angeordnet ist. Hierdurch wird der Stator 1 geringfügig um eine Drehachse 4 verschwenkt, welche durch das Filmscharnier 9 verläuft.The shifting drawer rail 7 comes into contact with a mechanical stop 5, which is arranged on the upper side of the stator 1. As a result, the stator 1 is slightly pivoted about an axis of rotation 4, which passes through the film hinge 9.
Vorzugsweise sollte das Material des mechanischen Anschlags 5 derart gewählt werden, dass Reibkräfte bei Berührung minimiert werden, um ein optimales Gleitverhalten des Läufers 2 zu erzielen. Bevorzugte Materialien sind gleitmodifizierte POM oder Teflon.Preferably, the material of the mechanical stop 5 should be selected such that frictional forces are minimized on contact in order to achieve optimum sliding behavior of the rotor 2. Preferred materials are slip-modified POM or Teflon.
Der mechanische Anschlag 5 ist so ausgeführt, dass bei einer Schrägstellung keine mechanische Überbestimmung auftreten kann. Dies verhindert ein Verkanten des Linearmotors.The mechanical stop 5 is designed so that when tilted no mechanical overdetermination can occur. This prevents tilting of the linear motor.
Fig. 4 zeigt eine ähnliche Situation, bei der es zu einer relativen Verdrehung von Ladenschiene 7 und Korpusschiene 6 gekommen ist. Wiederum wird ein Anliegen von Läufer 2 und Stator 1 durch eine Drehung entlang des Filmscharniers 9 verhindert (analog zur Vergrößerung A), wobei die für die Drehung notwendige Kraftausübung wieder durch die Ladenschiene 7 über den mechanischen Anschlag 5 erfolgt.Fig. 4 shows a similar situation in which there has been a relative rotation of drawer rail 7 and cabinet rail 6. Again, a concern of runner 2 and stator 1 is prevented by a rotation along the film hinge 9 (analogous to the magnification A), wherein the necessary force for the rotation force exercise again takes place through the drawer rail 7 via the mechanical stop 5.
Fig. 5 zeigt eine Explosionsdarstellung der in den vorgehenden Figuren 1 bis 4 dargestellten Anordnung, allerdings unter Weglassung der Korpusschiene 6.FIG. 5 shows an exploded view of the arrangement shown in the preceding FIGS. 1 to 4, but omitting the carcass rail 6.
In Fig. 6 ist der Drehmoment M bei einer Drehung zwischen Läufer 2 und Stator 1 um einen Drehwinkel φ entlang der Drehachse 4 ausgehend von der in Fig. 2 dargestellten Nullposition dargestellt. Erkennbar ist einerseits ein elastische Rückstellkraft Feι, welche linear vom Drehwinkel φ abhängt und für die Nullposition Null beträgt. Diese Rückstellkraft wird in dem in den Figuren gezeigten Ausführungsbeispiel durch die Materialelastizität des Filmschamiers 9 selbst zur Verfügung gestellt. Weiters ist eine stufenförmige Kurve erkennbar, welche Reibkräfte FFRIC symbolisiert, die verhindern sollen, dass bereits Querkräfte, welche im normalen Betrieb des Elektromotors auftreten (das heißt, so lange es zu keiner Veränderung der Lage zwischen Stator 1 und Läufer 2 quer zur gedachten Linie 3 kommt) zu einer Bewegung zwischen Läufer 2 und Stator 1 führen. In Fig. 6, the torque M is shown at a rotation between rotor 2 and stator 1 by a rotational angle φ along the axis of rotation 4, starting from the zero position shown in Fig. 2. Recognizable on the one hand, an elastic restoring force F e ι, which depends linearly on the rotational angle φ and is zero for the zero position. This restoring force is provided in the embodiment shown in the figures by the material elasticity of the film hinge 9 itself. Furthermore, a step-shaped curve can be seen, which symbolizes frictional forces F F RI C , which should prevent that already transverse forces, which occur during normal operation of the electric motor (that is, as long as there is no change in the position between the stator 1 and rotor 2 across imaginary line 3) lead to a movement between rotor 2 and stator 1.
