Description

Einstellmechanismus für Autoscheinwerfer  Adjustment mechanism for car headlights
Gebiet der Technik Field of engineering
Die Erfindung betrifft eine Konstruktion für einen Einstellmechanismus für Autoscheinwerfer, vornehmlich die einzelnen Scheinwerfer-Komponenten. The invention relates to a construction for an adjustment mechanism for car headlights, especially the individual headlight components.
Bisheriger Stand der Technik Previous state of the art
Jeder Scheinwerfer muss die Anforderung an die seitliche Einstellung und die Einstellung der Höhe der Reflektoren (oder die Xenon/LED Module) erfüllen, auf der Grundlage der Kundenspezifikation (Automobilfabrikspezifikation). Es geht um die manuelle Positionseinstellung der Innenkomponenten. Diese Kundenspezifikation kommt zu den gesetzlichen Anforderungen, die erfüllt werden müssen, hinzu. Each headlight must meet the lateral adjustment and height adjustment requirements of the reflectors (or xenon / LED modules), based on the customer specification (automotive factory specification). It is about the manual position adjustment of the inner components. This customer specification adds to the legal requirements that need to be met.
Die Einstellung der Innenkomponenten (das Reflektor System oder die Xenon/LED Module) wird derzeit durch die beweglichen Reiter, deren Position durch die Rotation der Einstellschrauben gegeben wird (normalerweise über ein Kegelrad), gelöst. Dieses Prinzip ermöglicht es die richtige Position einzustellen, zum Beispiel bei der Herstellung oder bei der technischen Kontrolle. Die horizontale Schraube dreht sich dank der Rotation des Kegelrades um. Die horizontale Schraube leitet die Translation der Reiter ab, welche die ModulVReflektor läge bestimmen.  The adjustment of the internal components (the reflector system or the xenon / LED modules) is currently solved by the movable riders whose position is given by the rotation of the adjusting screws (usually via a bevel gear). This principle makes it possible to set the correct position, for example in the production or in the technical control. The horizontal screw rotates thanks to the rotation of the bevel gear. The horizontal screw derives the translation of the tabs that determine the modulus reflector.
Zum einen müssen die Einstellsysteme (die Reiter und die Einstellschrauben) die Bewegung ermöglichen, zum anderen müssen sie aber auch der Forderung an die maximale Steifigkeit entsprechen , und zwar wegen der Forderung an die Stabilität der Hell-Dunkel Grenze in 25 Meters Entfernung. Wenn es Toleranzen bzw. Spiel in dem System gibt, dann wirkt es sich mit der Vibration der Lichtverteilung auf der Fahrbahn aus. Die erlaubte Amplitude der Vibration beträgt, in Abhängigkeit vom Hersteller ca. 0,2%.  On the one hand, the adjustment systems (the riders and the adjusting screws) must allow the movement, on the other hand they must also meet the requirement for maximum rigidity, because of the requirement for the stability of the cut-off at 25 meters distance. If there are tolerances in the system, then it will affect the vibration of the light distribution on the road. The permitted amplitude of the vibration is about 0.2% depending on the manufacturer.
Die mechanische Belastung, die dynamische Belastung (die Vibration, die Fremdenerweckung) , die Schwerpunktposition der Module/Reflektoren und die Position der Spannpunkte generieren die Reaktionskräfte bzw. die Spannungszustände in Materialen. Diese Reaktionen belasten die Spannpunkte der Reiter, wobei die Reiter die Schnittstelle zwischen den Reflektoren/Modulen (der bewegliche Teil) und den Scheinwerferkörper (der feste Teil)darstellen. Die Reaktionskräfte zwischen den Reflektoren/Modulen und dem Gehäuse werden über die Reiter übertragen. Die Module/Reflektoren wiegen durchschnittlich 750 g. Die Beschleunigung kann bis zu 10 G betragen. Das bekannte System, verwendet für die Positionseinstellung mit den genannten Komponenten und der dafür bestimmten Führung in dem Scheinwerferkörper, sehr robuste Elemente, die die Nuten erhalten, welche zu der Führung der Reiter, die in die Führungsnut eingeschoben ist, dienen. Die Reiterposition wird dann mit der Rotation der Stellschraube bestimmt. Die Translation der Reiter erfolgt mit Hilfe des metrischen oder anderen Gewindes. Bei dieser Weise der Position Einstellung und die Forderung an der Genauigkeit der Einstellung ist eine Lösung notwendig, bei der vornehmlich die Axial- und Radial- Systemtoleranz (von der Reiter und von der Stellschraube), exakte Ausführung der Nuten, und einer insgesamt hohen Steifigkeit u. ä.. Die Reiter haben abgefederte Elemente für die Toleranzelimination, wobei zu weiche elastische Komponenten dann Einfiuss auf die Vibration der Hell-Dunkel- Grenze haben. The mechanical load, the dynamic load (the vibration, the alien awakening), the center of gravity position of the modules / reflectors and the position of the clamping points generate the reaction forces or stress states in materials. These reactions stress the tension points of the riders, with the riders representing the interface between the reflectors / modules (the moving part) and the headlight body (the fixed part). The reaction forces between the reflectors / modules and the housing are transmitted via the tabs. The modules / reflectors weigh on average 750 g. The acceleration can be up to 10G. The known system, used for the position adjustment with the said components and the particular guide in the headlight body, very robust elements which receive the grooves, which serve to guide the rider, which is inserted into the guide groove. The rider position is then determined by the rotation of the set screw. The translation of the riders takes place with the help of metric or other threads. In this way, the position adjustment and the demand for the accuracy of the adjustment, a solution is necessary in which primarily the axial and radial system tolerance (of the rider and the set screw), exact design of the grooves, and a total high rigidity u , ä .. The riders have sprung elements for the tolerance elimination, too soft elastic components then have an influence on the vibration of the cut-off.
In den einigen Fällen wird das Problem mit den Schwingungen des Scheinwerfers, durch eine Doppel-Lagerung zu der Erhöhung der Steifigkeit gelöst. Diese Lösung erfordert zusätzliche Komponenten und Schrauben.  In some cases, the problem with the oscillations of the headlamp, is solved by a double-bearing to increase the rigidity. This solution requires additional components and screws.
Begründung der Erfindung Statement of the invention
Die angeführte Mängel werden durch den erfindungsgemäßen Einstellmechanismus für Autoscheinwerfer beseitigt. Die Erfindung besteht darin, dass ein Rahmen, als ein untrennbares Ganzes, aus einem festen Rahmenteil besteht, der mit einem beweglichen Rahmenteil verbunden ist, wobei der feste und der bewegliche Rahmenteil mithilfe zweier kinematischer Komponenten verbunden sind, die jeweils in dem Anschlusspunkt zu dem festen und dem beweglichen Rahmenteil verdünnt sind. Das feste Rahmenteil weist einen Abschnitt auf mit dem die kinematischen Komponenten verbunden sind sowie einen Abschnitt für die eine Aufnahme der Stellschraube, wobei die beiden Abschnitte in einem Winkel zueinander stehen. In der Aufnahme für die Stellschraube befindet sich eine Nut. In der kinematischen Komponente, die näher an dem festen Rahmenteil angeordnet ist, befindet sich eine Durchführung in der die Stellschraube angeordnet werden kann. An dem beweglichen Rahmenteil befindet sich zwischen den beiden kinematischen Komponenten eine Gewindebuchse für die Stellschraube Die Stellschraube wird in die Aufnahme am festen Rahmenteil, in die Durchfuhrung der kinetischen Komponente und der Gewindebuchse eingelegt, wobei die Stellschraube einen Bund aufweist, der in der Nut des festen Rahmenteiles drehbar gelagert ist. Dadurch wird die Stellschraube in dem festen Rahmenteil abgestützt, so dass das Gewinde der Stellschraube, das in der Gewindebuchse des beweglichen Rahmenteils läuft, den beweglichen Rahmenteil in Richtung der Schraubenachse verschiebt, wenn die Stellschraube gedreht wird. Der Rahmen ist ein einstöckiges Bauteil, das aus dem festen Rahmenteil dem beweglichen Rahmenteil und den kinetischen Komponenten besteht, wobei der Rahmen aus einem elastischen thermoplastischen Material bestehen kann. . The cited defects are eliminated by the adjustment mechanism according to the invention for car headlights. The invention consists in that a frame, as an inseparable whole, consists of a fixed frame part, which is connected to a movable frame part, wherein the fixed and the movable frame part are connected by means of two kinematic components, each in the connection point to the fixed and the movable frame part are diluted. The fixed frame part has a portion to which the kinematic components are connected and a portion for receiving the adjusting screw, wherein the two portions are at an angle to each other. There is a groove in the receptacle for the set screw. In the kinematic component, which is arranged closer to the fixed frame part, there is a passage in which the adjusting screw can be arranged. On the movable frame part is located between the two kinematic components a threaded bushing for the set screw The set screw is inserted into the receptacle on the fixed frame part, in the passage of the kinetic component and the threaded bush, the screw has a collar which is in the groove of the fixed Frame part is rotatably mounted. Thereby, the adjusting screw is supported in the fixed frame part, so that the thread of the adjusting screw, which runs in the threaded bushing of the movable frame part, displaces the movable frame part in the direction of the screw axis when the adjusting screw is turned. The frame is a one-piece component consisting of the fixed frame part, the movable frame part and the kinetic components, wherein the frame may be made of an elastic thermoplastic material. ,
Das feste Rahmenteil und das bewegliche Rahmenteil sowie die Kinematischen Komponenten sind an den Übergängen lokal dünner ausgeführt so dass hier jeweils ein Filmgelenk entsteht. Die zu den Filmgelenken gehörende Schwenkachse verläuft senkrechten zu der Richtung der Bewegung des beweglichen Rahmenteils.. Der geometrischen Ausführung der Verdünnung entspricht die Bedingung der gegenüberliegenden Seiten, und zwar horizontal und vertikal. Die horizontalen und vertikalen Seiten sind einander senkrecht. Auf diese Weise entsteht ein Parallelogramm Mechanismus mit vier Gelenken. Zu diesem trägt auch das elastische thermoplastische Material des Rahmens bei. Wenn das entstandene Parallelogramm verschiedene Rahmenlänge hat, verwendet man die Kinematik zur Kompensation der Bewegung vom Endpunkt nach der spezifischen Anforderungen.  The fixed frame part and the movable frame part as well as the kinematic components are made locally thinner at the transitions so that in each case a film joint is formed. The pivot axis associated with the film hinges is perpendicular to the direction of movement of the movable frame member. The geometrical design of the dilution corresponds to the condition of the opposite sides, horizontal and vertical. The horizontal and vertical sides are perpendicular to each other. In this way, a parallelogram mechanism with four joints is created. The elastic thermoplastic material of the frame also contributes to this. If the resulting parallelogram has different frame length, the kinematics are used to compensate for the movement from the end point to the specific requirements.
Der Vorteil der Vorrichtung ist der feste Rahmen und auch die Begrenzung seines Axialspieles. Es ist nicht notwendig wie im Stand der Technik die Position des Reiters und der Stellschraube einzustellen, sowie eine präzise Ausführung der Nuten und ihrer Einstellung, insbesondere das Axialspiel des Systems.  The advantage of the device is the fixed frame and also the limitation of its axial play. It is not necessary as in the prior art to adjust the position of the rider and the set screw, as well as a precise design of the grooves and their adjustment, in particular the axial play of the system.
Auf die beschriebene Weise ist es möglich, die Höheneinstellung und auch die Seiteneinstellung zu realisieren.  In the manner described, it is possible to realize the height adjustment and also the side adjustment.
Erklärung die Figuren auf der Zeichnung Explanation the figures on the drawing
Die Erfindung wird mithilfe der Zeichnung näher erklärt. In der Figur 1 wird eine vorgeschlagene Lösung auf dem Prinzip des Parallelogramms für die Höheneinstellung der Autoscheinwerfer gezeigt. The invention will be explained in more detail with reference to the drawing. In the figure 1 a proposed solution is shown on the principle of the parallelogram for the height adjustment of the car headlights.
Beispiel für die Ausführung der Erfindung Example of the embodiment of the invention
Ein praktisches Beispiel der Einstellmechanismus für Autoscheinwerfer entsprechend der Erfindung ist in der Figur 1 gezeigt. A practical example of the headlamp adjustment mechanism according to the invention is shown in FIG.
In Figur 1 ist der Rahmen, als ein untrennbares Ganzes gezeigt, der aus dem festen Rahmenteil l und dem beweglichen Rahmenteil 2 gebildet wird, welche mithilfe zweier kinematischer Komponenten 3 verbunden sind, die in dem Anschlusspunkt verdünnt, das heißt als Filmgelenk ausgeführt sind. Die Nut 6 des festen Rahmenteiles ist in dem festen Rahmenteil I ausgebildet, in der kinematischen Komponente 3, die näher dem festen Rahmenteil 1 eingestellt ist, ist die Durchführung 7 der kinematischen Komponente angefertigt. Die Gewindebuchse 5 die sich an dem beweglichen Rahmenteil befindet ist zwischen beiden kinematischen Komponenten 3 angeordnet. Die Stellschraube 4 ist in der Gewindebuchse 5 und in die Nut 6 des festen Rahmenteiles eingelegt. Über ein Kegelradgetriebe 8 wird die Stellschraube 4 angetrieben und damit wird das bewegliche Rahmenteil eingestellt.. Die kinematischen Komponenten (3) haben die gleiche Länge und der Abstand zwischen ihnen ist konstant auf der ganzen Länge. In figure 1, the frame is shown, as an inseparable whole, formed by the fixed frame part 1 and the movable frame part 2, which are connected by means of two kinematic components 3 which are thinned in the connection point, that is to say as a film hinge. The groove 6 of the fixed frame part is formed in the fixed frame part I, in the kinematic component 3, the closer to the fixed frame part. 1 is set, the implementation 7 of the kinematic component is made. The threaded bushing 5 which is located on the movable frame part is arranged between the two kinematic components 3. The adjusting screw 4 is inserted in the threaded bushing 5 and in the groove 6 of the fixed frame part. Via a bevel gear 8, the adjusting screw 4 is driven and thus the movable frame part is adjusted .. The kinematic components (3) have the same length and the distance between them is constant over the entire length.
Der feste Rahmenteil 1^ und der bewegliche Rahmenteil 2 und die beiden kinematischen Komponenten 3, die gemeinsam den gesamten Rahmen bilden, bestehen aus einem thermoplastischen Material. Die Verdünnung zwischen den kinematischen Komponenten 3 in dem Anschlusspunkt zu den beiden Rahmenteilen, beträgt in diesem Fall 4 mm2 Der horizontale Weg, den der bewegliche Rahmenteil auf dem Prinzip des Parallelogramms beruhend zurücklegen kann, beträgt in der Richtung der Achse der Stellschraube 4, plus/minus 5 mm. Durch die Schieb-Pendelbewegung entsteht ein Höhenversatz von 0,05mm. The fixed frame part 1 ^ and the movable frame part 2 and the two kinematic components 3, which together form the entire frame, consist of a thermoplastic material. The dilution between the kinematic components 3 in the connection point to the two frame parts is 4 mm 2 in this case. The horizontal path that the movable frame part can travel based on the principle of the parallelogram is in the direction of the axis of the adjusting screw 4, plus / minus 5 mm. The sliding pendulum movement creates a height offset of 0.05mm.
Die lokalen Verdünnungen stellen dem kinematischen Mechanismus vier Gelenke für die Verbindung mit den vier festen Komponenten her, wobei einzelne Komponenten immer Teilstücke sind. Die Verbindungslinien des Rahmens verrichten die gleichmäßige Drehbewegung nach der Verdünnungsachse, die letzte verrichtet dann die gekrümmte Bewegung-das Prinzip von dem Parallelogramm. Die Vergleichung zu der Bewegung auf dem Parallelogramms Prinzip kommt aus den Längen von den einzelnen Komponenten, wann beide kinematischen Komponenten die gleiche Länge haben und die Entfernung ist konstant zwischen ihnen. Der bewegliche Rahmensteil 2 wird mithilfe der Stellschraube 4 geführt.  The local dilutions provide the kinematic mechanism with four joints for connection to the four solid components, with individual components always being sections. The connecting lines of the frame perform the uniform rotary motion on the dilution axis, the latter then performs the curved movement-the principle of the parallelogram. The comparison to the movement on the parallelogram principle comes from the lengths of the individual components, when both kinematic components have the same length and the distance is constant between them. The movable frame part 2 is guided by means of the adjusting screw 4.
