Description
In Kraftfahrzeugen werden zunehmend Hochfrequenzsenderempfängerbauteile oder Radarsensoren eingesetzt, um beispielsweise eine Kommunikation für ein schlüsselloses Zugangssystem zu ermöglichen. Möglich ist auch deren Einsatz bei Abstandsmessgeräten, um beispielsweise den Abstand zu vorausfahrenden Fahrzeugen konstant zu halten oder bei Einparkhilfevorrichtungen. Solche Radarsensoren werden aber auch eingesetzt, um Objekte in einem zu überwachenden Bereich zu erkennen, beispielsweise eine Fußgeste, um den Kofferraumdeckel zu öffnen, aber auch um einen Spalt in einer Spulenanordnung zur induktiven Energieübertragung zum Laden von Batterien zu überwachen, um störende Objekte insbesondere lebende Objekte wie Katzen erkennen zu können.High-frequency transmitter-receiver components or radar sensors are increasingly being used in motor vehicles, for example to enable communication for a keyless entry system. They can also be used in distance measuring devices, for example to keep the distance to vehicles ahead constant or in parking assistance devices. Such radar sensors are also used to detect objects in an area to be monitored, for example a foot gesture to open the trunk lid, but also to monitor a gap in a coil arrangement for inductive energy transfer to charge batteries in order to be able to detect disturbing objects, especially living objects such as cats.
Hierfür ist es jedoch nötig, die hochfrequente Strahlung auf den Bereich zu fokussieren, der tatsächlich überwacht werden soll und insbesondere die Detektionsempfindlichkeit in benachbarten Bereichen stark zu reduzieren, um Reaktionen, die durch die Detektion solcher Objekten eingeleitet bzw. ausgelöst werden, nicht unnötig hervorzurufen. Zwar soll beispielsweise das induktive Laden mit hoher Leistung unterbrochen werden, wenn sich ein Lebewesen im Spalt zwischen einer sendenden Bodenplatte und dem empfangenen Fahrzeug befindet, andererseits jedoch nicht abgeschaltet werden, wenn sich dieses Lebewesen nur in der Nähe vorbei bewegt.However, this requires the high-frequency radiation to be focused on the area that is actually to be monitored and, in particular, the detection sensitivity in neighboring areas must be greatly reduced in order to avoid unnecessary reactions that are initiated or triggered by the detection of such objects. For example, inductive charging at high power should be interrupted if a living being is in the gap between a transmitting floor plate and the receiving vehicle, but on the other hand it should not be switched off if this living being is just moving past nearby.
Eine richtungsabhängige Empfindlichkeit solcher HF- bzw. Radarsensoren kann beispielsweise durch Antennengruppen oder Phase-Array-Antennen oder aber auch mittel Reflektoren oder Direktoren oder spezieller Antennenbauformen erreicht werden. Denkbar sind auch Mischformen oben genannter Lösungen. Allerdings erfordern diese Lösungen kostenintensive Auslegungen der Antennen bzw. Sensoren oder der zusätzlichen Reflektoren bzw. Direktoren.A direction-dependent sensitivity of such HF or radar sensors can be achieved, for example, by means of antenna groups or phase array antennas or by means of reflectors or directors or special antenna designs. Mixed forms of the above solutions are also conceivable. However, these solutions require cost-intensive designs of the antennas or sensors or the additional reflectors or directors.

Hierdurch kann allerdings Schmutz in das Gehäuse eindringen und die Antenne oder weitere elektronische Bauteile in ihrer Funktion beeinträchtigen.However, this can allow dirt to enter the housing and impair the function of the antenna or other electronic components.

Die
Es ist daher die Aufgabe der Erfindung, diese Nachteile zu vermeiden.It is therefore the object of the invention to avoid these disadvantages.
Die Aufgabe wird gelöst durch ein Gehäuse für einen Radarsensor gemäß Anspruch 1. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.The object is achieved by a housing for a radar sensor according to
Demnach sind bei einem Gehäuse für einen Radarsensor die Gehäusewände aus Material mit für hochfrequente elektromagnetische Wellen dämpfenden Eigenschaften gebildet, wobei in erfindungsgemäßer Weise die Gehäusewände in zumindest zwei unterschiedlichen Raumrichtungen unterschiedliche Wanddicken aufweisen und die Gehäusewände derart ausgebildet sind, dass die hochfrequenten elektromagnetischen Wellen durch die Wände mit größerer Wanddicke stärker gedämpft werden als durch die Wände mit geringerer Wanddicke. Das Gehäuse hat eine im Wesentlichen kreissektorförmige Grundfläche, bei der die Kreisradien einen rechten Winkel bilden und dessen an dem Kreisbogen befindliche Gehäusewand eine geringere Dämpfung aufweist als die an den Kreisradien befindlichen Gehäusewände.Accordingly, in a housing for a radar sensor, the housing walls are made of material with damping properties for high-frequency electromagnetic waves, wherein in the manner according to the invention the housing walls are divided into at least two have different wall thicknesses in different spatial directions and the housing walls are designed in such a way that the high-frequency electromagnetic waves are more strongly attenuated by the walls with greater wall thickness than by the walls with lesser wall thickness. The housing has a base area essentially shaped like a sector of a circle, in which the circular radii form a right angle and whose housing wall located on the circular arc has a lower attenuation than the housing walls located on the circular radii.
Hierdurch ist es auf besonders einfache Weise möglich, in einem Fertigungsschritt ein Gehäuse herzustellen, das die gewünschte Richtungscharakteristik hat, wobei die unterschiedlichen Wanddicken stufenlos ineinander übergehen können. Ferner kann durch eine im Gehäuse angeordnete Hochfrequenzantenne vor allem in einem Raumbereich abgestrahlt werden, der durch die beiden etwa rechtwinklig zueinander angeordneten Kreisradiengehäusewände begrenzt wird.This makes it particularly easy to produce a housing in one production step that has the desired directional characteristics, whereby the different wall thicknesses can merge seamlessly into one another. Furthermore, a high-frequency antenna arranged in the housing can radiate primarily in a spatial area that is delimited by the two circular radius housing walls arranged approximately at right angles to one another.
In einer Weiterbildung des erfindungsgemäßen Gehäuses können die Wanddicken auch mit unterschiedlichen Materialien gebildet sein, die unterschiedliche Dämpfungswerte für hochfrequente elektromagnetische Strahlung haben.In a further development of the housing according to the invention, the wall thicknesses can also be formed with different materials that have different attenuation values for high-frequency electromagnetic radiation.
Eine vorteilhafte Anwendung des erfindungsgemäßen Gehäuses ist durch eine Vorrichtung zur Übertragung elektrischer Energie mittels induktiver Kopplung und zur Erkennung von Körpern im Kopplungsbereich mittels Radarsensoren gegeben, wobei die Ansprechempfindlichkeit der Radarsensoren für Körper außerhalb des Kopplungsbereichs wesentlich geringer ist und bei der am Außenrand des Kopplungsbereichs zumindest zwei Radarsensorgehäuse gemäß der Ansprüche 1 bis 3 angeordnet sind.An advantageous application of the housing according to the invention is provided by a device for transmitting electrical energy by means of inductive coupling and for detecting bodies in the coupling area by means of radar sensors, wherein the response sensitivity of the radar sensors for bodies outside the coupling area is significantly lower and in which at least two radar sensor housings according to
Durch die zumindest zwei Radarsensoren in erfindungsgemäßen Gehäusen kann der sich zwischen diesen Radarsensorgehäusen befindliche Raum gut überwacht werden, ohne dass störende Objekte außerhalb dieses Bereichs die Empfindlichkeit des Radarsensors negativ beeinflussen. Besonders vorteilhaft ist eine etwa quadratische Vorrichtung an deren vier Ecken jeweils ein erfindungsgemäßer Radarsensor in einem erfindungsgemäßen Gehäuse angeordnet ist.By having at least two radar sensors in housings according to the invention, the space between these radar sensor housings can be monitored well without disturbing objects outside this area negatively affecting the sensitivity of the radar sensor. A roughly square device is particularly advantageous, with a radar sensor according to the invention arranged at each of its four corners in a housing according to the invention.
