Abstract
Description
Die Erfindung geht aus von einem Kameramodul mit einer Linse, mit einer Auswerteeinheit, insbesondere einem Charge-coupled-device und mit einer Abdeckscheibe, wie sie beispielsweise zur Überwachung des Umfelds am hinteren Ende eines Kraftfahrzeugs eingesetzt werden.The Invention is based on a camera module with a lens, with a Evaluation unit, in particular a batch-coupled device and with a Cover, as for example, to monitor the environment at the rear End of a motor vehicle are used.
Wenn diese Kameramodule in einem Kraftfahrzeug zur Überwachung des rückwärtigen Umfelds eingesetzt werden, werden sie in der Regel in die Heckklappe des Fahrzeugs integriert.If These camera modules in a motor vehicle for monitoring the rear environment They are usually used in the tailgate of the Integrated vehicle.
Ähnlich aufgebaute Kameramodule können auch für die stationäre Überwachung von Gebäuden, Hauseingängen oder öffentlichen Plätzen eingesetzt werden, so dass die Erfindung auch bei solchen Kameramodulen anwendbar ist.Similarly constructed Camera modules can also for the stationary monitoring be used by buildings, doorways or public spaces, so that the invention is also applicable to such camera modules.
Da die Funktion des Kameramoduls einen ungestörten Strahlengang durch die Abdeckscheibe, die Linse bis zu der Auswerteeinheit voraussetzt, arbeiten diese Kameramodule nur dann störungsfrei und ordnungsgemäß, wenn die Abdeckscheibe trocken ist und keine Wassertropfen auf der Abdeckscheibe den Strahlengang beieinträchtigen.There the function of the camera module an undisturbed beam path through the Cover disc, which requires lens up to the evaluation unit, These camera modules only work properly and properly when the cover is dry and no drops of water on the cover affect the beam path.
In andern Worten: Bei Regen oder nach einer Wäsche des Kameramoduls sind viele Tropfen auf der Abdeckscheibe naturgemäß nicht trocken ist, aufweist.In In other words, when it rains or after a wash of the camera module are many drops on the cover naturally not dry, has.
Der Erfindung liegt die Aufgabe zugrunde, ein Kameramodul bereit zu stellen, dessen Funktionsbereitschaft auch unter widrigen Wetterumständen uneingeschränkt vorhanden ist.Of the Invention is based on the object, a camera module ready to whose operational readiness is unrestricted even under adverse weather conditions is.
Diese Aufgabe wird bei einem Kameramodul mit eine Linse, mit einer Auswerteeinheit und mit einer Abdeckscheibe erfindungsgemäß dadurch gelöst, dass auf der Abdeckscheibe und das Kameramodul arbeitet nicht störungsfrei. Dies gilt entsprechend auch für Kameramodule ohne Abdeckscheibe. In diesem Fall befinden sich die Tropfen auf der Linse.These Task becomes with a camera module with a lens, with an evaluation unit and solved with a cover according to the invention that on the cover and the camera module does not work smoothly. This also applies accordingly Camera modules without cover. In this case are the Drop on the lens.
Durch die erfindungsgemäße Maßnahme kann die Abdeckscheibe bei Regen, bei Schneefall oder nachdem die Abdeckscheibe z. B. durch eine eigens dafür vorgesehene Wascheinrichtung gereinigt wurde, schnell getrocknet werden oder trocken gehalten werden, so dass der Strahlengang durch die Abdeckscheibe und die Linse auf die Auswerteeinheit unabhängig von den äußeren Witterungsbedingungen immer ungestört ist und somit die Funktion des Kameramoduls stets gewährleistet ist.By the measure according to the invention can the cover in rain, snow or after the cover z. B. by a specially for it provided washing device was cleaned, dried quickly be kept or dry, so that the beam path through the cover and the lens on the evaluation regardless of the outside weather conditions always undisturbed is and thus always ensures the function of the camera module is.
Varianten der Erfindung sehen vor, dass die Widerstandsheizung so auf der Abdeckscheibe angeordnet ist, dass der Strahlengang durch die Linse nicht beeinträchtigt wird. Dies kann vorteilhafter Weise dadurch realisiert werden, dass die Widerstandsheizung in Form eines Kreises oder Kreisausschnittes beziehungsweise in Form mehrerer konzentrisch angeordneter Kreise oder Kreisausschnitte auf der Abdeckscheibe angeordnet ist. Dadurch ergibt sich auch, obwohl die erfindungsgemäße Widerstandsheizung nur bei näherer Betrachtung erkennbar, ein ansprechendes Erscheinungsbild der Widerstandsheizung und damit des Kameramoduls insgesamt.variants The invention provide that the resistance heating so on the Cover disc is arranged that the beam path through the lens is not impaired becomes. This can be realized advantageously in that the resistance heating in the form of a circle or circular cutout or in the form of several concentrically arranged circles or circular cutouts is arranged on the cover. Thereby also results, although the resistance heating according to the invention only at closer View recognizable, an appealing appearance of resistance heating and thus the camera module as a whole.
Die erfindungsgemäße Widerstandsheizung kann auf die Abdeckscheibe aufgedruckt und anschließend gesintert werden. Bei Bedarf kann die Widerstandsheizung im Anschluss an das Sintern auch noch zusätzlich verstärkt vergütet und gegen Umwelteinflüsse geschützt werden. Diese Widerstandsheizungen eignen sich besonders, wenn die Abdeckscheibe aus normalen Glas oder aus Einscheibensicherheitsglas hergestellt wird.The Resistance heating according to the invention can printed on the cover and then sintered. at Need the resistance heating after sintering also additionally reinforced hardened and tempered and against environmental influences protected become. These resistance heaters are particularly suitable when the Cover made of normal glass or toughened safety glass will be produced.
Alternativ kann die Widerstandsheizung auch aus Heizdrähten bestehen, die in eine Klebefolie eingebettet sind. Diese Klebefolie wird auf die Abdeckscheibe aufklebt, so dass auch das Nachrüsten bereits in Serie produzierter Kameramodule mit einer erfindungsgemäßen Widerstandsheizung möglich ist.alternative The resistance heating can also consist of heating wires, which in a Adhesive film are embedded. This adhesive film is applied to the cover sticks, so that the retrofitting already in series produced camera modules with a resistance heating according to the invention is possible.
Es hat sich als vorteilhaft erwiesen, wenn die Heizleistung der Widerstandsheizung steuerbar ist. Besonders vorteilhaft ist es, wenn die Heizleistung der Widerstandsheizung in Abhängigkeit der Ausgangssignale eines Regensensors gesteuert wird. Durch diese Art der Steuerung ist unter allen Umständen gewährleistet, dass die Abdeckscheibe trocken ist. Dabei wird das elektrische Bordsnetz des Kraftfahrzeugs nicht mehr als nötig beansprucht.It has proved to be advantageous when the heating power of the resistance heating is controllable. It is particularly advantageous if the heating power of the Resistance heating in dependence the output signals of a rain sensor is controlled. Through this Type of control is guaranteed under all circumstances that the cover is dry. In this case, the electrical system of the motor vehicle not more than necessary claimed.
Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Zeichnung, deren Beschreibung und den Patentansprüchen entnehmbar.Further Advantages and advantageous embodiments of the invention are the subsequent drawing, the description and the claims can be removed.
