Description
Stand der TechnikState of the art
Reifensensoren werden insbesondere zur Messung des Reifendrucks, d.h. als so genannte Reifendruckkontrollsysteme (TPMS) verwendet. Sie werden üblicherweise als Sensormodule an der Felge oder am Ventil des Reifens angebracht und übertragen ihre Daten drahtlos mit Hilfe einer Antenne an eine Empfangseinrichtung des Fahrzeuges, die sie zu einem zentralen Steuergerät des Fahrzeuges weiterleitet.tire sensors In particular, for measuring the tire pressure, i. as so-called Tire Pressure Monitoring Systems (TPMS) used. They usually become mounted as sensor modules on the rim or on the valve of the tire and transfer their data wirelessly by means of an antenna to a receiving device of the vehicle, which turns it into a central control unit of the vehicle forwards.
Die Antenne ist im Allgemeinen als Draht außerhalb des Sensors vorgesehen. Bei der Montage des Sensormoduls im Reifen durch z.B. Einvulkanisieren ist die Antenne daher ihrer Konstruktion entsprechend auszurichten, was entsprechend aufwendige Montageschritte zur Folge hat.The Antenna is generally provided as a wire outside the sensor. When mounting the sensor module in the tire by e.g. vulcanizing the antenna is therefore to be aligned according to its construction, which has correspondingly complicated assembly steps result.
Offenbarung der ErfindungDisclosure of the invention
Der Erfindung liegt der Gedanke zugrunde, die Antenne mit einer weitgehend homogenen Abstrahleigenschaft bzw. Antenneneigenschaft in einer Ebene auszubilden. Hierzu wird sie in oder auf dem Schaltungsträger als Schleifenantenne bzw. Loop-Antenne, d. h. in einer im wesentlichen geschlossenen Form ausgebildet, die einen Schleifenbereich umfasst. Vorteilhafterweise ist sie im Wesentlichen rund oder ganz rund ausgebildet und erstreckt sich in einem Außenbereich des Schaltungsträgers. Die Antenne kann hierbei z.B. auf der Rückseite, der Vorderseite oder in einer Zwischenebene des die Bauelemente aufnehmenden Schaltungsträgers angeordnet sein.Of the Invention is based on the idea of the antenna with a largely homogeneous emission property or antenna property in one plane train. For this purpose, it is in or on the circuit carrier as Loop antenna or loop antenna, d. H. in a substantially formed closed form, which includes a loop area. Advantageously, it is substantially round or completely round and extends in an outdoor area of the circuit board. The Antenna hereby may e.g. on the back, the front or arranged in an intermediate plane of the components receiving the circuit substrate be.
Dem liegt die Erkenntnis zugrunde, dass eine Antenne, die eine homogene Abstrahlung in einer Ebene aufweist, auch bei einer beliebigen Platzierung im Fahrzeugreifen ein hinreichendes Antennensignal zu der am Fahrzeugchassis vorgesehenen Empfangseinrichtung abgeben kann.the is based on the knowledge that an antenna that is a homogeneous Radiation in a plane, even at any placement in the vehicle tire a sufficient antenna signal to the vehicle chassis provided receiving device can deliver.
Der Schaltungsträger kann insbesondere in einem Gehäuse aufgenommen werden; alternativ hierzu kann er jedoch auch z. B. eingegossen werden. Weiterhin können z. B. auch zwei Substrate derartig miteinander verbunden, z. B. verlötet oder verklebt werden, dass zwischen ihnen eine Kavität ausgebildet wird, in der die Elemente aufgenommen sind.Of the circuit support especially in a housing be included; Alternatively, however, he can also z. B. be poured. Furthermore you can z. As well as two substrates such interconnected, z. B. soldered or glued, that forms a cavity between them becomes, in which the elements are taken up.
Vorteilhafterweise wird der Schaltungsträger des Sensormoduls rotationssymmetrisch um die Symmetrieachse der Schleifenantenne ausgebildet; bei Aufnahme in einem Gehäuse wird auch dieses entsprechend rotationssymmetrisch ausgebildet. Hierdurch ergeben sich mehrere Vorteile: Die Antenne kann am Außenumfang des runden Schaltungsträgers ausgebildet werden und somit die zur Verfügung stehende Fläche bei rotationssymmetrischer Abstrahlungscharakteristik ausnutzen.advantageously, becomes the circuit carrier of the Sensor module rotationally symmetrical about the axis of symmetry of the loop antenna educated; when accommodated in a housing, this also becomes appropriate formed rotationally symmetrical. This results in several Advantages: The antenna can be formed on the outer circumference of the circular circuit carrier and thus the available standing area take advantage of rotationally symmetric radiation characteristics.
Eine Form ohne Ecken und Kanten, insbesondere eine runde Form des Gehäuses, ermöglicht die Einbindung in das Gummimaterial des Fahrzeugreifens, ohne störend für die im Betrieb auftretenden Verformungen des Fahrzeugreifens zu sein.A Shape without corners and edges, in particular a round shape of the housing, allows the Integration in the rubber material of the vehicle tire, without disturbing the in the Operational deformations of the vehicle tire to be.
Es ist eine hierdurch eine Anbringung des Sensormoduls bzw. Reifensensormoduls im Gummimaterial ohne aufwendige Montage in grundsätzlich beliebiger Ausrichtung ermöglicht. Das Sensormodul kann somit in das Gummimaterial einvulkanisiert werden, insbesondere auch in der Lauffläche oder im Bereich der Lauffläche.It is thereby an attachment of the sensor module or tire sensor module in rubber material without complex assembly in basically any Alignment allows. The sensor module can thus be vulcanized into the rubber material be, especially in the tread or in the tread area.
Vorteilhaft ist die Ausbildung eines relativ kleinen HF-Bereichs auf der Oberseite des Schaltungsträgers, der z.B. kleiner/gleich 40 %, vorzugsweise kleiner/gleich 25 % der Oberseite des Schaltungsträgers einnimmt. Weiterhin sind vorteilhafterweise keine großflächigen Metallbereiche in oder an dem Schaltungsträger ausgebildet; auch werden vorzugsweise geschlossene Leiterbahnen vermieden. Erfindungsgemäß wurde erkannt, dass durch diese an sich nicht aufwendigen Maßnahmen in überraschender Weise eine sehr homogene Abstrahlcharakteristik einer Loop-Antenne erreicht werden konnte.Advantageous is the formation of a relatively small RF area on the top the circuit board, the e.g. less than or equal to 40%, preferably less than or equal to 25% of Top of the circuit board occupies. Furthermore, advantageously no large-area metal areas in or on the circuit carrier educated; also preferably closed interconnects avoided. According to the invention was recognized that by these in themselves not consuming measures in a surprise Way a very homogeneous emission characteristics of a loop antenna could be achieved.
Als niederfrequente Bauelemente sind das Sensorelement und ein Sensor-Steuerschaltkreis vorgesehen, der vorzugsweise als Sensor-ASIC ausgebildet ist; als hochfrequente Bauelemente sind ein Oszillator und ein HF-Schaltkreis vorgesehen, der z. B. als RF-ASIC ausgebildet ist. Bei der Herstellung des erfindungsgemäßen Sensormoduls wird der bestückte Schaltungsträger in ein Gehäuse aus z.B. Kunststoff eingesetzt.When Low-frequency components are the sensor element and a sensor control circuit provided, which is preferably designed as a sensor ASIC; as high-frequency Components are an oscillator and an RF circuit provided, the z. B. as RF ASIC is formed. In the manufacture of the sensor module according to the invention is the stocked circuit support in a housing from e.g. Plastic used.
