Abstract

A joystick control unit has a ball shaped unit (8) supported within plastic bearing elements (4, 6) at the top and a ring (18) at the bottom. Inset into the ball is a permanent magnet (19) and between the bearings are 4 pole shoes. Yoke elements (13, 14) project into the base and are separated. A Hall effect sensor measures the magnet flux in a gap (13a) and this is dependent upon the position of the joystick.

Description

Zum Steuern von Verkehrsmitteln werden oft kardanisch gelagerte Steuerknüppel verwendet, also Steuerknüppel, die in zwei zueinander senkrechten Richtungen verschwenkbar sind: So kann mit dem Steuerknüppel im Flugzeug durch das Vor- und Zurückschwenken das Höhenleitwerk betätigt werden, während durch ein Verschwenken nach der Seite die Verwindungsklappen betätigt werden. In kleinen Fahrzeugen mit zwei angetriebenen Rädern und zwei Nachlaufrädern wird mit dem Vorwärts- und Rückwärtsverschwenken die Geschwindigkeit beim Vorwärtsfahren resp. beim Rückwärtsfahren gesteuert, während das seitliche Verschwenken eine unterschiedliche Drehzahl der beiden angetriebenen Räder und damit eine Änderung der Fahrtrichtung bewirkt.To control transportation are often gimbal Stored joystick used, so joystick that in two mutually perpendicular directions can be swiveled: can with the joystick in the plane through the fore and aft Swing back the tailplane to be operated while by pivoting to the side the torsion flaps be operated. In small vehicles with two powered Wheels and two trailing wheels comes with the forward and Backward panning the speed when driving forward resp. controlled when reversing while the side Swiveling a different speed of the two driven wheels and thus a change in the direction of travel causes.

Falls zum Betätigen der betreffenden Organe keine großen Kräfte aufgewendet werden müssen, können diese Organe über Seilzüge mit dem Steuerknüppel verbunden sein, so daß eine direkte Bewegungsübertragung erfolgt. Falls aber die Verwendung irgendwelcher Kraftverstärker nötig oder wünschbar ist, können zwei Potentiometer verwendet werden, die dem Auslenkwinkel entsprechende Ausgangsspannungen liefern. Es gibt auch induktive Steuerknüppel, bei denen mehr oder weniger aufwendige Anordnungen von Spulen und Magnetkernen sowie natürlich auch eine entsprechend aufwendige Elektronik nötig sind. Aus der japanischen Patentschrift 58 066 381 (Anmelde- Nummer 81 016 5228) ist ein an seinem einen Ende mit einer in einem Käfig frei verschwenkbaren Kugel versehener Hebel bekannt, wobei die Kugel einen hohlzylindrischen, axial magnetisierten Permanentmagneten enthält, der auf zwei im Lagergehäuse untergebrachte Hall-Sensoren einwirkt. Da sowohl die Kugel wie auch die sie umschließenden Lagerteile aus magnetisch nicht leitendem Material bestehen, handelt es sich um ein offenes Magnetfeld, so daß die Sensoren in jeder Lage der Kugel vom Magnetfeld durchflossen sind.If not large to operate the organs in question Forces that need to be exerted can be over these organs Cables are connected to the joystick so that a direct motion transmission takes place. But if that Use of any booster necessary or desirable two potentiometers can be used, the Deflection angle deliver corresponding output voltages. It are also inductive joysticks where more or less elaborate arrangements of coils and magnetic cores as well Naturally, correspondingly complex electronics are also necessary are. From Japanese patent specification 58 066 381 (application Number 81 016 5228) is one at one end with an in Lever provided with a cage that can be pivoted freely known, the ball being a hollow cylindrical, axial contains magnetized permanent magnets, which on two in Hall sensors housed in the bearing housing. Because both  the ball as well as the bearing parts surrounding it magnetically non-conductive material, it is around an open magnetic field, so that the sensors in any position the magnetic field flows through the ball.

All die vorgenannten mechanischen, elektrischen und elektronischen Übertragungsmittel lassen sich natürlich nicht nur zum Betätigen beweglicher Teile verwenden; entsprechend ausgebildete Steuerknüppel werden auch zur Steuerung von Elektro-Straßenfahrzeugen sowie zur Fernsteuerung von Modellfahrzeugen und -flugzeugen benützt, aber auch für elektronische Spiele und auch für die Arbeit am PC, also als Betätigungsorgan zum Verschieben des Cursors. Die vorgenannten Übertragungsmittel lassen sich aber auch dazu benützen, die Stellung des Steuerknüppels anzuzeigen, also eine zweidimen­ sionale Messeinrichtung zu erhalten.All the aforementioned mechanical, electrical and electronic means of transmission are of course not possible use only to operate moving parts; corresponding Trained joysticks are also used to control Electric road vehicles and for remote control of Model vehicles and planes used, but also for electronic games and also for working on the PC, so as Actuator for moving the cursor. The aforementioned Transmission means can also be used to Display the position of the joystick, so a two-dim to obtain a standard measuring device.

Ziel der vorliegenden Erfindung ist nun die Schaffung einer zum zweidimensionalen Steuern oder auch zum zwei­ dimensionalen Messen dienende Anordnung mit zwei magnetisch beeinflußbaren Sensoren und einem räumlich verschwenkbaren Steuerknüppel, der an seinem einen Ende eine schwenkbar gelagerte Gelenkkugel aufweist, in welcher ein kreisring­ förmiger, achsial magnetisierter Permanentmagnet untergebracht ist. Diese neue Anordnung soll einerseits gegenüber dem, was aus der vorgenannten japanischen Patentschrift bekannt ist, eine nicht unbedeutende Verbesserung in bezug auf die Unempfindlichkeit gegen äußere Störfelder haben und andererseits eine gegenüber den übrigen bekannten Anordnungen wesentlich vereinfachte Konstruktion aufweisen und sich dadurch preiswert herstellen und auch dort unterbringen lassen, wo für den Einbau nur sehr wenig Platz vorhanden ist. Gelöst wird diese Aufgabe dadurch, daß die Gelenkkugel Teile aus magnetisch leitendem Material aufweist, zwischen denen der Permanentmagnet gehalten ist, und daß vier regelmäßig verteilt angeordnete Polschuhe vorhanden sind, von denen je zwei einander gegenüberliegende durch ein Joch miteinander verbunden sind, wobei jedes Joch einen Luftspalt hat, in welchem ein Hall-Sensor zur Messung des Flusses im Luftspalt oder der Änderung dieses Flusses angeordnet ist, wobei die Polschuhe so angeordnet sind, daß alle Polschuh-Achsen in einer gemeinsamen durch das Zentrum der Gelenkkugel gehende Ebene liegen und daß der kreisringförmige Permanentmagnet derart in der Gelenkkugel angeordnet ist, daß in der Mittelstellung des Steuerknüppels diese Ebene für den Permanentmagneten eine senkrecht zu seiner Achse stehende Symmetrie-Ebene bildet.The aim of the present invention is now to create one for two-dimensional control or two Dimensional measuring arrangement with two magnetic influenceable sensors and a spatially pivotable Joystick that swivels at one end bearing ball joint in which a circular ring shaped, axially magnetized permanent magnet is. This new arrangement is intended on the one hand to what is known from the aforementioned Japanese patent specification, a not insignificant improvement in terms of Have insensitivity to external interference fields and on the other hand, one compared to the other known arrangements have significantly simplified construction and themselves thereby produce inexpensively and also accommodate there leave where there is very little space for installation. This problem is solved in that the joint ball parts made of magnetically conductive material, between which the Permanent magnet is held, and that four regularly Distributed pole pieces are available, each of which two opposite each other through a yoke  are connected, each yoke having an air gap, in which is a Hall sensor for measuring the flow in the air gap or the change in this flow is arranged, the Pole shoes are arranged so that all of the pole shoe axes are in a common one going through the center of the joint ball Plane and that the annular permanent magnet is arranged in the joint ball such that in the Center position of the joystick this level for the Permanent magnet a perpendicular to its axis Plane of symmetry.

Nachfolgend wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel der erfindungsgemäßen Anordnung beschrieben. In der Zeichnung zeigtBelow is a based on the attached drawing Embodiment of the arrangement according to the invention described. In the drawing shows

Fig. 4 den isolierten Steuerknüppel in etwas größerem Maßstab. Fig. 4 shows the isolated joystick on a somewhat larger scale.

Wie aus der Zeichnung ersichtlich ist, wird das Gehäuse zur Lagerung des erfindungsgemäßen Steuerknüppels durch einen Topf 1 und einen Deckel 2 gebildet, die beide aus magnetisch abschirmendem Material, wie beispielsweise Eisen, bestehen. Der Deckel 2 weist eine zentrale Öffnung 2a auf, in welcher vier an einem Träger 16 befestigte, aus Kunststoff bestehende Lagerklötze 4, 5, 6, 7 sitzen, die zusammen das obere Lager für die Gelenkkugel 8 bilden. In diesem auf Säulen 17 sitzenden Träger 16 ruht ein ebenfalls aus Kunststoff bestehender Ring 18, der das untere Lager für die Gelenkkugel 8 und mit dem oberen Lager zusammen die Halterung für diese Kugel bildet. Jeweils zwischen zwei Lagerklötzen ist einer der vier Polschuhe 9, 10, 11 und 12 angeordnet, von denen jeweils zwei einander gegenüberliegende durch ein am Träger 16 befestigtes Joch 13 bzw. 14 miteinander verbunden sind. Dabei sind alle Polschuhe so angeordnet, daß ihre Achsen 9a, 10a, 11a und 12a in einer gemeinsamen, die Trennfläche zwischen dem oberen und dem unteren Lager bildenden, durch das Zentrum 8a der Gelenkkugel 8 gehenden Ebene liegen. Jedes der beiden Joche 13 und 14 besitzt einen Luftspalt, von denen in der Fig. 1 der Spalt 13a im Joch 13 sichtbar ist. In diesem ist ein Hall-Sensor 15 zur Messung des magnetischen Flusses ange­ ordnet, wie das beispielsweise aus der japanischen Patent­ schrift 63 038 168 (Anmelde-Nummer 86 018 2155) bekannt ist.As can be seen from the drawing, the housing for mounting the control stick according to the invention is formed by a pot 1 and a cover 2 , both of which are made of magnetically shielding material, such as iron. The lid 2 has a central opening 2 on a, in which four fixed to a support 16, made of plastic bearing pads 4, 5, 6, seats 7, which together form the upper bearing for the joint ball. 8 In this carrier 16, which is seated on columns 17 , a ring 18 , also made of plastic, rests, which forms the lower bearing for the joint ball 8 and together with the upper bearing the holder for this ball. One of the four pole shoes 9 , 10 , 11 and 12 is arranged between two bearing blocks, two of which are connected to each other by a yoke 13 and 14 fastened to the carrier 16 . All pole pieces are arranged so that their axes 9 a, 10 a, 11 a and 12 a lie in a common plane that forms the interface between the upper and lower bearings and passes through the center 8 a of the joint ball 8 . Each of the two yokes 13 and 14 has an air gap, of which the gap 13 a in the yoke 13 is visible in FIG. 1. In this, a Hall sensor 15 for measuring the magnetic flux is arranged, as is known for example from the Japanese patent 63 038 168 (application number 86 018 2155).

Mit 15a ist das Kabel bezeichnet, das den Sensor mit einer Speise- und Meßvorrichtung verbindet. Die Gelenkkugel 8 besteht aus zwei angenähert gleich großen Teilen 8b und 8c aus magnetisch leitendem Material, zwischen denen ein kreisringförmiger, achsial magnetisierter Permanentmagnet 19 untergebracht ist, der sich bis zur Kugeloberfläche erstrecken oder von einem Ring 20 aus magnetisch nicht leitendem Material umgeben sein kann, dessen äußere Fläche einen Teil der Kugeloberfläche bildet. Vertikal durch die Kugel 8 hindurch­ geführt ist ein Stab 21, der zusammen mit der Gelenkkugel 8 den Steuerknüppel bildet. Der Permanentmagnet 19 ist derart in der Gelenkkugel 8 angeordnet, daß in der Mittelstellung des Steuerknüppels 21 die Achse des hohlzylinderförmigen Magneten 14 senkrecht auf der Trennebene zwischen dem oberen und dem unteren Lager steht und diese ihn in der Mitte schneidet, also eine Symmetrie-Ebene für den Magneten bildet. Das freie Ende 21a des Stabes 21 steckt in einem Handgriff 22 aus Kunststoff, der über einen mit ihm ein einziges Werkstück bildenden Faltenbalg 23 mit dem Deckel 2 verbunden ist. Eine Schraubenfeder 24, die zwischen einem durch Seeger-Ringe 25 auf dem Stab 21 festgehaltenen Abstützring 26 und einem auf diesem Stab verschiebbar gelagerten, auf der Ringscheibe 3 aufliegen­ den Gleitstück 27 eingespannt ist, dient als Rücksteller, damit der Steuerknüppel im unbetätigten, also unbelasteten Zustand stets in die in der Zeichnung dargestellte Lage zurückkehrt.With 15 a the cable is designated, which connects the sensor with a feeding and measuring device. The joint ball 8 consists of two approximately equal parts 8 b and 8 c made of magnetically conductive material, between which an annular, axially magnetized permanent magnet 19 is accommodated, which extend to the surface of the ball or be surrounded by a ring 20 made of magnetically non-conductive material can, whose outer surface forms part of the spherical surface. Is vertically guided by the ball 8 through a rod 21 forming the control stick together with the joint ball. 8 The permanent magnet 19 is arranged in the joint ball 8 so that in the central position of the control stick 21, the axis of the hollow cylindrical magnet 14 is perpendicular to the parting plane between the upper and the lower bearing and this cuts it in the middle, that is, a plane of symmetry for forms the magnet. The free end 21 a of the rod 21 is in a handle 22 made of plastic, which is connected to the cover 2 via a bellows 23 forming a single workpiece with it. A coil spring 24 , which is clamped between a support ring 26 held by Seeger rings 25 on the rod 21 and a slidably mounted on this rod, lying on the ring disk 3, the slide 27 serves as a reset so that the joystick in the unactuated, i.e. unloaded Condition always returns to the position shown in the drawing.

Es ist nun ohne weiteres einleuchtend, daß sich beim Verschwenken des Steuerknüppels 8/21 in der Ebene senkrecht zur Verbindungslinie der beiden Polschuhe 9 und 11 der magnetische Fluß in dem diese beiden Polschuhe verbindenden Joch 13 nicht ändert, daß jedoch im anderen Joch 14 eine Flußänderung erfolgt, die auf den im Spalt dieses Jochs angeordneten Hall-Sensor einwirkt, so daß die Änderung in einer nachgeschalteten, in der Zeichnung nicht dargestellten Meßvorrichtung gemessen und/oder in einem nachgeschalteten ebenfalls nicht dargestellten Verstärker zur Steuerung irgendwelcher Bewegungsabläufe verwendet werden kann.It is now obvious that when the control stick 8/21 is pivoted in the plane perpendicular to the connecting line of the two pole shoes 9 and 11, the magnetic flux in the yoke 13 connecting these two pole shoes does not change, but that in the other yoke 14 a change in flow takes place, which acts on the arranged in the gap of this yoke Hall sensor, so that the change can be measured in a downstream measuring device, not shown in the drawing and / or used in a downstream amplifier, also not shown, to control any movement sequences.

Ein Verschwenken des Steuerknüppels 8/21 in der Ebene senkrecht zur Verbindungslinie der beiden Polschuhe 10 und 12 ist in der dem Hall-Sensor 15 nachgeschalteten Meßvorrichtung feststellbar, so daß ein Verschwenken in irgendeiner Zwischen- Richtung einen entsprechenden Einfluß auf die beiden Meßvorrichtungen und/oder Verstärker hat.A pivoting of the control stick 8/21 in the plane perpendicular to the connecting line of the two pole shoes 10 and 12 can be determined in the measuring device connected downstream of the Hall sensor 15 , so that pivoting in any intermediate direction has a corresponding influence on the two measuring devices and / or Amplifier.

Aus dem Vorgenannten ist ohne weiteres ersichtlich, daß es sich um eine konstruktiv einfache und genau arbeitende Anordnung handelt. Es ist möglich, die Vorrichtung groß oder klein zu bauen, ohne daß etwas an der Arbeits- oder Anzeigegenauigkeit verloren geht.From the above it is readily apparent that it is a constructively simple and precise working Arrangement. It is possible to make the device large or large to build small without anything at work or Display accuracy is lost.

Selbstverständlich ist es auch bei dieser Anordnung ohne weiteres möglich, den Stab 21 an seinem unteren Ende mit einem Betätiger 21b zu versehen, der zur Betätigung eines Sicherheits­ schalters dient, der die beiden den Hall-Sensoren nachge­ schalteten Organe in der neutralen Stellung, also der Mittelstellung des Steuerknüppels blockiert.Of course, it is also easily possible in this arrangement to provide the rod 21 at its lower end with an actuator 21 b, which is used to actuate a safety switch, the two organs connected downstream of the Hall sensors in the neutral position, that is the central position of the control stick is blocked.
