Abstract
Sicherheitseinrichtung für ein Kraftfahrzeug mit einer von wenigstens einem Unfallsensor (18) beaufschlagbaren Abschalteinrichtung, durch die eine elektrische Energiequelle von einem Bordnetz des Kraftfahrzeugs abtrennbar ist, und die ein mit Treibenergie beaufschlagbares Trennmittel aufweist, durch das ein zum Bordnetz gehörender Stromleiter in einer zur Unterbrechung des Stromflusses führenden Weise auftrennbar ist, dadurch gekennzeichnet, dass als Trennmittel ein mit Treibenergie beaufschlagbarer und als Stromleiter wirksamer Sollbruchkörper vorgesehen ist.safety device for a Motor vehicle with one of at least one accident sensor (18) acted upon Deployment device, through which an electrical energy source of an electrical system of the motor vehicle is separable, and one with Having drift energy acted upon release agent by the one belonging to the electrical system Conductor in a leading to interrupt the flow of current Way can be separated, characterized in that as a release agent provided with a driving energy and effective as a conductor predetermined breaking body is.
Description
Die Erfindung betrifft eine Einrichtung für Kraftfahrzeuge zur unfallbedingten Trennung einer elektrischen Energiequelle von einem Bordnetz gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a device for motor vehicles for accident-related Separation of an electrical energy source from a vehicle electrical system according to the preamble of claim 1.

Der Erfindung liegt daher das technische Problem zugrunde, eine Sicherheitseinrichtung für ein Kraftfahrzeug zu schaffen, mittels derer einfach und zuverlässig eine elektrische Energiequelle von einem Bordnetz des Kraftfahrzeuges abtrennbar ist.The invention is therefore based on the technical problem of providing a safety device for a motor vehicle, by means of which easily and reliably an electrical energy source of an electrical system of the motor vehicle can be separated.
Diese Aufgabe wird gelöst durch die kennzeichnenden Merkmale des Patentanspruchs 1. Die Unteransprüche enthalten besonders zweckmäßige Weiterbildungen der Erfindung.These Task is solved by the characterizing features of claim 1. The dependent claims particularly expedient developments the invention.
Erfindungsgemäß wird also in die von der elektrischen Energiequelle zum Bordnetz des Kraftfahrzeugs führende Stromleitung ein Sollbruchkörper integriert, durch den der für das Bordnetz benötigte Strom hindurchfließt. Darüber hinaus ist dieser Sollbruchkörper mit Treibenergie beaufschlagbar, so daß er innerhalb der Abschalteinrichtung die Funktion eines Trennmittels übernimmt.Thus, according to the invention in the from the electrical energy source to the electrical system of the motor vehicle premier Power line integrates a breakaway body, by the one for the electrical system needed electricity flowing therethrough. About that In addition, this predetermined breaking body can be acted upon by driving energy, so that it within the shutdown device assumes the function of a release agent.
Bei einem besonders vorteilhaften Ausführungsbeispiel der Erfindung ist der Sollbruchkörper nach der Art einer Hülse gebildet, die als Sollbruchstelle eine umlaufende Ringnut aufweist. In das Innere der Hülse ist eine das Treibmittel enthaltende Sprengkapsel einschraubbar, die ihrerseits durch Signale des Unfallsensors aktivierbar ist. Der Sollbruchkörper dient somit gleichzeitig als Halterungselement für die Sprengkapsel. Über die zuvor beschriebenen Funktionsumfänge hinaus kann außerdem der Sollbruchkörper auch noch als Verbindungsmittel dienen, um beispielsweise eine an der elektrischen Energiequelle befestigbare Polklemme mit einer Kontaktplatte eines Stromkabels zu koppeln.at a particularly advantageous embodiment of the invention is the breaking point after the kind of a sleeve formed, which has a peripheral annular groove as a predetermined breaking point. Into the inside of the sleeve is a propellant containing explosive capsule screwed, which in turn can be activated by signals from the accident sensor. The predetermined breaking body thus serves simultaneously as a support element for the detonator. About the previously described functional scopes In addition, besides the predetermined breaking body also serve as a connecting means to, for example, an the electric power source attachable pole terminal with a Coupling contact plate of a power cable.
Der zuvor beschriebene Funktionsumfang kann ohne eine nennenswerte Bauraumaufwand im Batterieklemmenbereich erzielt werden. Insbesondere die Nähe zur Polklemme bewirkt, daß die Unterbrechung der Stromleitung ganz dicht am Batteriepol erfolgt und somit für die eigentliche Abschalteinrichtung keine zusätzlichen Stromleitungen verlegt werden müssen. Außerdem wird dadurch sichergestellt, daß nach der Betätigung der Sprengkapsel nicht durch lose umherliegende Batteriekabel weitere Kurzschlüsse erzeugt werden können. In der hülsenförmigen Ausgestaltung des Sollbruchkörpers ist noch als wesentlicher Vorteil herauszustellen, daß nach einer Aktivierung der Sprengkapsel das Treibmittel gerichtet aus der Hülse heraustritt, und zwar genau in Richtung eines beim Aufbruch der Sollbruchstelle ggf. entstehenden Lichtbogens. Dieser Lichtbogen wird durch das Treibmittel zuverlässig ausgeblasen. Zur Dämpfung der Explosionswirkung kann zwischen der Kontaktplatte und der Polklemme als federndes Isolationselement beispielsweise ein vorgespannter Gummiblock vorgesehen wer den, der nach der Explosion die zuvor verbundenen Teile zuverlässig auseinanderpreßt.Of the The scope of functions described above can be achieved without any significant space requirement be achieved in the battery terminal area. In particular the proximity to the pole terminal causes the Interruption of the power line is very close to the battery pole and thus for the actual shutdown device no additional power lines laid Need to become. Furthermore This ensures that after the operation the detonator does not generate additional short circuits due to loose battery cables can be. In the sleeve-shaped configuration the breaking body is still to prove as an essential advantage that after a Activation of the detonator, the propellant directionally emerges from the sleeve, exactly in the direction of the breaking point of the breaking point possibly resulting arc. This arc is through the Blowing agent reliably blown out. For damping the explosion effect can between the contact plate and the pole terminal as resilient insulation element, for example, a prestressed rubber block provided the who after the explosion, the previously connected Parts reliable auseinanderpreßt.
