Description

Die Erfindung geht aus von einem Steuergerät, insbesondere zur Verwendung in einem Kraftfahrzeug, mit einem Gehäuse und mit wenigstens einer im Gehäuse untergebrachten elektrischen und/oder elektronischen Schaltung, wobei das Gehäuse ein Grundteil und ein Deckelteil umfasst.The invention relates to a control device, in particular for use in a motor vehicle, having a housing and having at least one housed in the housing electrical and / or electronic circuit, wherein the housing comprises a base part and a cover part.

Derartige Steuergeräte finden in Kraftfahrzeugen in vielfältiger Art und Weise Verwendung. Die Steuergeräte müssen die darin untergebrachte elektrische und/oder elektronische Schaltung insbesondere luft- und feuchtigkeitsdicht aufnehmen. Dabei ist bekannt, das Gehäuse vollständig aus einem Kunststoff herzustellen.Such controllers are used in motor vehicles in a variety of ways use. The control units must accommodate the electrical and / or electronic circuit housed therein in particular air and moisture-proof. It is known to make the case completely made of a plastic.

Aus dem Stand der Technik ist es bekannt, das Gehäuseteil mit dem Deckelteil beispielsweise zu verschrauben, zu verrasten, zu vernieten, zu verschweißen oder zu verkleben. Derartige Verbindungen sind vergleichsweise aufwendig, da das Deckelteil und/oder das Grundteil entsprechend ausgebildet sein müssen. Ferner ist zu berücksichtigen, dass an Steuergeräte in Kraftfahrzeugen vergleichsweise hohe Anforderungen gestellt werden, insbesondere auch was die Umwelteinflüsse betrifft.From the prior art, it is known, for example, to screw the housing part with the cover part, to lock, rivet, to weld or to glue. Such compounds are relatively expensive, since the cover part and / or the base part must be designed accordingly. Furthermore, it must be taken into account that comparatively high demands are placed on control units in motor vehicles, in particular also with regard to the environmental influences.

Aus der DE 44 36 547 A1 , der DE 10 2006 033 580 A1 und der DE 93 21 910 U1 sind verschiedene Gehäuse für Elektronikbauteile bekannt.From the DE 44 36 547 A1 , of the DE 10 2006 033 580 A1 and the DE 93 21 910 U1 Different housing for electronic components are known.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Steuergerät der eingangs genannten Art dahingehend weiterzubilden, dass es auf einfache, kostengünstige und funktionssichere Art und Weise verschlossen werden kann.The present invention has the object of developing a control device of the type mentioned in such a way that it can be closed in a simple, cost-effective and functionally reliable manner.

Diese Aufgabe wird durch ein Steuergerät mit den Merkmalen des Anspruchs 1 gelöst. Das Steuergerät zeichnet sich also dadurch aus, dass der Gegenabschnitt mit der strukturierten Oberfläche unlösbar verzahnt ist, wobei die Verzahnung zwischen dem Fügeabschnitt und dem Gegenabschnitt Hinterschneidungen aufweist und mittels thermischem Aufschmelzen des Gegenabschnitts hergestellt ist.This object is achieved by a control device having the features of claim 1. The control unit is thus distinguished by the fact that the mating section is non-detachably toothed with the structured surface, the toothing having undercuts between the mating section and the mating section and being produced by means of thermal melting of the mating section.

Die strukturierte Oberfläche weist dabei vorzugsweise eine räumliche Struktur auf, die insbesondere auch Hinterschneidungen aufweist, die beim thermischen Aufschmelzen hintergriffen werden. Klemm-, Rast- oder Schraubverbindungen sind weder am Deckelteil noch am Grundteil vorzusehen. Insofern können Deckelteil und Grundteil vergleichsweise einfach aufgebaut sein und damit in ihrer Herstellung kostengünstig sein.The structured surface preferably has a spatial structure, which in particular also has undercuts which are engaged behind during the thermal melting. Clamping, latching or screw connections are not to be provided on the cover part or on the base part. In this respect, cover part and base can be constructed comparatively simple and thus be inexpensive to manufacture.

Zudem kann gewährleistet werden, dass eine solche Verbindung luft-, feuchtigkeitsdicht zudem unlösbar ist. Dadurch kann auch eine Manipulation der im Gehäuse vorgesehenen elektrischen Schaltkreise unterbunden werden.In addition, it can be ensured that such a connection is air-tight, moisture-proof and insoluble. As a result, manipulation of the electrical circuits provided in the housing can also be prevented.

Grundsätzlich stellt sich die Verwendung von beispielsweise dem Grundteil als Kunststoff-Bauteil und dem Deckelteil als Metall-Bauteil als problematisch heraus, insbesondere aufgrund den großen unterschiedlichen Wärmeausdehnungskoeffizienten. Deshalb ist es regelmäßig erforderlich, zwischen dem Kunststoff-Grundteil und einem Metall-Deckelteil eine zusätzliche Formdichtung vorzusehen. Die Erfindung hat dabei den Vorteil, dass keine weiteren Stoffe oder Formdichtungen zwischen dem Kunststoff-Bauteil und dem Metall-Bauteil vorgesehen werden müssen; durch die sich ergebende Verzahnung der beiden Bauteile kann eine dichte, dauerhafte und hohe Kräfte übertragende Verbindung bereitgestellt werden.In principle, the use of, for example, the base part as a plastic component and the cover part as a metal component turns out to be problematic, in particular due to the large different thermal expansion coefficients. Therefore, it is regularly necessary to provide an additional molded seal between the plastic base and a metal cover part. The invention has the advantage that no further substances or molded seals between the plastic component and the metal component must be provided; Due to the resulting toothing of the two components, a dense, durable and high-force transmitting connection can be provided.

Das Ausbilden des Grundteils oder des Deckelteils als Metall-Bauteil hat zudem den Vorteil, dass Wärme, die im Steuergerät durch Bestromung der Schaltung auftritt, günstig über das Metall-Bauteil abgeleitet werden kann. Ferner ist vorteilhaft, dass das Metall-Bauteil magnetische Strahlung abschirmt und damit sich eine gute EMV (elektromagnetische Verträglichkeit) ergibt.The formation of the base part or the cover part as a metal component also has the advantage that heat that occurs in the control unit by energizing the circuit, can be conveniently derived via the metal component. Furthermore, it is advantageous that the metal component shields magnetic radiation and thus results in a good EMC (electromagnetic compatibility).

Das Grundteil ist vorteilhaftweise wannenartig mit einem umlaufenden Rand ausgebildet, der den Gegenabschnitt bzw. den Fügeabschnitt bildet. Das Deckelteil ist demgegenüber vorzugsweise plattenartig ausgebildet und weist einen umlaufenden Fügeabschnitt bzw. Gegenabschnitt auf. Insbesondere dann, wenn das Grundteil als Kunststoff-Bauteil ausgebildet ist, kann das Deckelteil als Metallplatte ausgebildet sein, die einen entsprechenden, umlaufenden Fügeabschnitt aufweist.The base is advantageously trough-shaped with a peripheral edge, which forms the counter section or the joint section. By contrast, the cover part is preferably plate-like and has a circumferential joining section or counterpart section. In particular, when the base part is designed as a plastic component, the cover part may be formed as a metal plate having a corresponding, circumferential joining portion.

Vorteilhafterweise ist die Schaltung auf einer Leiterplatte angeordnet, wobei die Leiterplatte parallel zum Deckelteil verläuft. Insbesondere dann, wenn die Leiterplatte vergleichsweise nahe am Deckelteil, und wenn dieses Deckelteil als Metall-Bauteil ausgebildet ist, ergibt sich insgesamt eine hohe elektromagnetische Verträglichkeit. Zudem kann Wärme, die auf der Leiterplatte entsteht, über das Deckelteil günstig abgeleitet werden.Advantageously, the circuit is arranged on a printed circuit board, wherein the printed circuit board runs parallel to the cover part. In particular, when the circuit board is comparatively close to the cover part, and if this cover part is formed as a metal component, results in a high overall electromagnetic compatibility. In addition, heat generated on the circuit board can be conveniently derived via the cover part.

Ferner ist vorteilhaft, wenn das Metall-Bauteil einen Steckeranschluss für einen Potentialausgleich aufweist. Gerade dann, wenn das Deckelteil als plattenartiges Metall-Bauteil ausgebildet ist, kann der Steckeranschluss in der Plattenebene liegen. Der Steckeranschluss kann folglich mittels eines Kabels mit dem Null-Leiter bzw. mit Erde verbunden werden. Auch hierdurch ergibt sich eine günstige elektromagnetische Verträglichkeit.It is also advantageous if the metal component has a plug connection for equipotential bonding. Just when the cover part is designed as a plate-like metal component, the plug connection can lie in the plane of the plate. The plug connection can therefore be connected by means of a cable to the neutral conductor or to ground. This also results in a favorable electromagnetic compatibility.

Vorzugsweise wird das Steuergerät mit einem Verfahren zum dichten Verschließen des Steuergeräts verschlossen, wobei der Gegenabschnitt thermisch aufgeschmolzen wird und der Fügeabschnitt derart auf den Gegenabschnitt aufgepresst wird, dass nach Abkühlung der Fügeabschnitt mit dem Gegenabschnitt unlösbar verzahnt ist. Für das Verfahren werden keine besonderen Werkzeuge oder zusätzliche Fügemittel benötigt. Das Verfahren gewährleistet zudem, dass eine sichere, dauerhafte und dichte Verbindung zwischen dem Grundteil und dem Deckelteil bereitgestellt wird. Preferably, the control unit is closed by a method for sealing the control unit, wherein the counterpart section is thermally fused and the joining section is pressed against the mating section in such a way that, after cooling, the mating section is inseparably interlocked with the mating section. The process does not require any special tools or additional joining agents. The method also ensures that a secure, durable and tight connection between the base and the lid part is provided.

Gemäß dem Verfahren können zum thermischen Aufschmelzen des Gegenabschnitts Laser, heißes Gas und/oder eine Infrarotbestrahlung Verwendung finden.According to the method, laser, hot gas and / or infrared radiation may be used to thermally melt the counterpart portion.

Gemäß dem Verfahren ist auch denkbar, dass zunächst, oder nur, der Fügeabschnitt erwärmt wird und dass beim Aufpressen des Fügeabschnitt auf den Gegenabschnitt thermisch aufgeschmolzen wird. Das Erwärmen des Fügeabschnitts kann dabei mittels Laser, Induktion, heißem Gas oder auch mittels einer Flamme erfolgen.According to the method, it is also conceivable that first, or only, the joining section is heated and that, when the joining section is pressed onto the opposite section, it is thermally melted. The heating of the joining portion can be done by means of laser, induction, hot gas or by means of a flame.

Weitere Einzelheiten und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung zu entnehmen, anhand derer das in den Figuren gezeigte Ausführungsbeispiel näher beschrieben und erläutert wird.Further details and advantageous embodiments of the invention will become apparent from the following description, with reference to which the embodiment shown in the figures will be described and explained in more detail.

1 ein erfindungsgemäßes Steuergerät mit einer aufgeschnittenen Ecke; 1 an inventive control device with a cut corner;

2 den Ausschnitt II in 1 in Vergrößerung; und 2 the section II in 1 in magnification; and

3 den Ausschnitt III in 2 in Vergrößerung. 3 the section III in 2 in magnification.

In 1 ist ein Steuergerät 10 mit einem Gehäuse 12 gezeigt, wobei das Gehäuse ein wannenartig ausgebildetes Grundteil 14 und ein plattenartig ausgebildetes Deckelteil 16 umfasst. Im Gehäuse 12 ist eine Leiterplatte 18 untergebracht, auf der sich elektrische und/oder elektronische Schaltungen befinden.In 1 is a control unit 10 with a housing 12 shown, wherein the housing is a trough-like design base 14 and a plate-like trained cover part 16 includes. In the case 12 is a circuit board 18 accommodated on which electrical and / or electronic circuits are located.

Bei dem Steuergerät 10 handelt es sich beispielsweise um ein Steuergerät zur Ansteuerung eines Verbrennungsmotors.At the control unit 10 For example, it is a control device for controlling an internal combustion engine.

Wie aus den 1 und 2 deutlich wird, weist das wannenartig ausgebildete Grundteil 14 einen umlaufenden Rand 20 auf, an dessen Oberseite ein Gegenabschnitt 22 vorgesehen ist. Der Gegenabschnitt 22 ist, wie aus 2 deutlich wird, stegartig ausgebildet und ist in Richtung des Deckelteils 16 erhaben. Das Deckelteil 16, das aus einem metallischen Werkstoff ist, weist auf seiner dem Gegenabschnitt zugewandten Seite einen ebenfalls umlaufenden Fügeabschnitt 24 auf. In 1 ist der Verlauf des Fügeabschnitts 24 durch eine gestrichelte Linie angedeutet.Like from the 1 and 2 becomes clear, has the trough-like design base 14 a circumferential edge 20 on, at the top of a counter section 22 is provided. The counterpart 22 is how out 2 becomes clear, web-like and is in the direction of the cover part 16 sublime. The lid part 16 , which is made of a metallic material, has on its side facing the counter portion a likewise circumferential joining portion 24 on. In 1 is the course of the joining section 24 indicated by a dashed line.

Wie aus der Vergrößerung gemäß 3 deutlich wird, weist der Fügeabschnitt 24 eine strukturierte Oberfläche 26 auf. Die räumlich strukturierte Oberfläche 26 ist dabei insbesondere mittels Lasern in das Deckelteil 16 eingebraucht. Mit der strukturierten Oberfläche 26 ist der Gegenabschnitt 22 räumlich verzahnt. Die Verzahnung wird dabei durch Aufschmelzen des Gegenabschnitts 22 und durch aneinanderpressen des Deckelteils 16 gegen das Grundteil 14 hergestellt. Die strukturierte Oberfläche 26 ist dabei vorzugsweise so ausgebildet, dass die Verzahnung zwischen Fügeabschnitt 24 und Gegenabschnitt 22 Hinterschneidungen aufweist, wodurch eine unlösbare Verbindung zwischen dem Deckelteil und dem Grundteil hergestellt wird. Insgesamt wird dadurch das Deckelteil 16 mit dem Grundteil 14 luft- und feuchtigkeitsdicht dauerhaft verbunden.As from the magnification according to 3 becomes clear, the joining section shows 24 a structured surface 26 on. The spatially structured surface 26 is in particular by means of lasers in the lid part 16 is needed. With the structured surface 26 is the opposite section 22 spatially interlocked. The toothing is thereby by melting the counterpart section 22 and by pressing together the lid part 16 against the base 14 produced. The structured surface 26 is preferably designed so that the teeth between joining section 24 and counterpart section 22 Undercuts has, whereby a permanent connection between the cover part and the base is made. Overall, this is the cover part 16 with the basic part 14 Permanently connected air- and moisture-proof.

Wie aus 1 deutlich wird, ist die Leiterplatte 18 im Grundteil 14 parallel zum Deckelteil 16 angeordnet, und zwar vergleichsweise nahe am Deckelteil 16. Dadurch, dass das Deckelteil 16 als Metall-Bauteil ausgebildet ist, schirmt es die Leiterplatte 18 weitestgehend ab und trägt damit zu einer guten elektromagnetischen Verträglichkeit des Steuergeräts 10 bei. Ferner kann über das metallische Bauteil durch Bestromung der Leiterplatte 18 entstehende Wärme aus dem Inneren des Gehäuses 12 über das Deckelteil 16 abgeführt werden.How out 1 becomes clear, is the circuit board 18 in the basic part 14 parallel to the lid part 16 arranged, and comparatively close to the lid part 16 , As a result, the lid part 16 is designed as a metal component, it shields the circuit board 18 As far as possible and thus contributes to a good electromagnetic compatibility of the controller 10 at. Furthermore, via the metallic component by energizing the circuit board 18 resulting heat from the interior of the housing 12 over the lid part 16 be dissipated.

Das Fügen des Deckelteils 16 mit dem Grundteil 14 kann zum einen dadurch erfolgen, dass der Gegenabschnitt 22 thermisch erwärmt wird und das nach dem Erwärmen des Gegenabschnitts 22 der Fügeabschnitt 24 an den Gegenabschnitt 22 angepresst wird. Das thermische Aufschmelzen des Gegenabschnitts 22 kann insbesondere mittels Laser, heißem Gas und/oder Infrarotbestrahlung erfolgen.The joining of the cover part 16 with the basic part 14 On the one hand can be done by the counter section 22 is heated thermally and after heating the counterpart section 22 the joining section 24 to the opposite section 22 is pressed. The thermal melting of the counterpart section 22 can be done in particular by means of laser, hot gas and / or infrared radiation.

Alternativ oder zusätzlich ist denkbar, dass das Deckelteil 16, und/oder dessen Fügeabschnitt 24 erwärmt wird und dass beim Aneinanderpressen des Deckelteils 16 an das Grundteil 14 aufgrund des erwärmten Fügeabschnitts 24 der Gegenabschnitt 22 aufgeschmolzen wird. Ein Erwärmen des Fügeabschnitts 24 kann beispielsweise mittels Laser, Induktion, heißem Gas und/oder mittels einer Flamme erfolgen.Alternatively or additionally, it is conceivable that the cover part 16 , and / or its joining section 24 is heated and that when pressing against the lid part 16 to the basic part 14 due to the heated joining section 24 the counterpart 22 is melted. Heating the joining section 24 can be done for example by means of laser, induction, hot gas and / or by means of a flame.

Wie aus 1 zudem deutlich wird, weist das Deckelteil 16 einen sich in Richtung der Ebene des Deckelteils 16 erstreckenden Steckeranschluss 28 auf. An diesen Steckeranschluss 28 kann ein Potentialausgleich angeschlossen werden. Auch dies trägt zu einer guten elektromagnetischen Verträglichkeit bei.How out 1 also becomes clear, the lid part 16 one in the direction of the plane of the cover part 16 extending connector 28 on. To this connector 28 a potential equalization can be connected. This also contributes to a good electromagnetic compatibility.
