Die Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebenen Merkmale gelöst.The object is achieved by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Erfindung betrifft eine Sicherheitsvorrichtung zur Verringerung einer Kollisionsschwere eines Fahrzeuges mit einem elektrischen Energiespeicher und mit einer Kollisionssensorik zur Erfassung einer dem Fahrzeug bevorstehenden Kollision. The invention relates to a safety device for reducing a collision severity of a vehicle with an electrical energy store and with a collision sensor system for detecting a collision imminent to the vehicle.
Erfindungsgemäß umfasst die Sicherheitsvorrichtung zumindest eine pyrotechnische Treibladung zur Trennung einer Verbindung zwischen dem am Fahrzeugboden befestigten elektrischen Energiespeicher und dem Fahrzeugboden zumindest bei einer erfassten, dem Fahrzeug bevorstehenden Kollision, zumindest einen mit zumindest einer pyrotechnischen Treibladung gekoppelten Anker, wobei die Treibladung den Anker nach Trennung der Verbindung zwischen elektrischem Energiespeicher und Fahrzeugboden in einer Fahrbahnoberfläche verankert und zumindest einer an dem elektrischen Energiespeicher und dem zumindest einen Anker angeordneten Seilbremse und eine an dem elektrischen Energiespeicher angeordnete Seilbremse mit zumindest einer pyrotechnischen Treibladung zur Verankerung des elektrischen Energiespeichers an einer Fahrbahnoberfläche.According to the invention, the safety device comprises at least one pyrotechnic propellant charge for separating a connection between the electrical energy store attached to the vehicle floor and the vehicle floor at least for a detected collision imminent to the vehicle, at least one anchor coupled to at least one pyrotechnic propellant charge, the propellant charging the armature after separation Anchored connection between the electric energy storage and the vehicle floor in a road surface and at least one arranged on the electrical energy storage and the at least one armature cable brake and arranged on the electric energy storage cable brake with at least one pyrotechnic propellant charge for anchoring the electrical energy storage on a road surface.
Mittels der Sicherheitsvorrichtung ist der elektrische Energiespeicher aus einem aus der bevorstehenden Kollision resultierenden Gefahrenbereich positionierbar und ist mittels der Seilbremse gegen ein beschleunigungsbedingtes Verrutschen auf der Fahrbahnoberfläche gesichert.By means of the safety device, the electrical energy store can be positioned from a danger area resulting from the impending collision and is secured by means of the rope brake against acceleration-related slipping on the road surface.
Aufgrund der Trennung des elektrischen Energiespeichers von dem Fahrzeug verringert sich die Masse des Fahrzeuges, wodurch gleichzeitig eine Kollisionsenergie verringert ist. Zudem wirken aufgrund der geringeren Masse des Fahrzeuges geringere Beschleunigungskräfte auf Insassen des Fahrzeuges, wobei eine Struktur des Fahrzeuges im Kollisionsfall weniger beansprucht wird.Due to the separation of the electrical energy storage device from the vehicle, the mass of the vehicle is reduced, which simultaneously reduces collision energy. In addition, due to the lower mass of the vehicle, lower acceleration forces act on the occupants of the vehicle, whereby a structure of the vehicle is less stressed in the event of a collision.
Weiterhin ist das Risiko einer kollisionsbedingten Verformung des elektrischen Energiespeichers erheblich vermindert, so dass eine Brandgefahr des elektrischen Energiespeichers ebenfalls vermindert ist.Furthermore, the risk of a collision-induced deformation of the electrical energy storage is significantly reduced, so that a fire hazard of the electrical energy storage is also reduced.
