Description
Die vorliegende Erfindung betrifft einen Hochvoltspeicher für eine unfallsichere Montage in einem Kraftfahrzeug sowie eine Anordnung, umfassend den in einer Fahrzeugkarosserie montierten Hochvoltspeicher.The present invention relates to a high-voltage storage for accident-proof mounting in a motor vehicle and to an arrangement comprising the high-voltage accumulator mounted in a vehicle body.
Hochvoltspeicher in Kraftfahrzeugen kommen insbesondere zum Antrieb von Hybrid-Fahrzeugen oder Elektrofahrzeugen zur Anwendung. Nach dem Stand der Technik werden Hochvoltspeicher mit zusätzlichen Strukturen im Fahrzeug geschützt, um im Crash-Fall keinen sicherheitskritischen Zustand zu erzeugen. Insbesondere müssen auch nach einem Unfall die Sicherheitsanforderungen z. B. der Berührschutz gegenüber den Hochvoltkomponenten, gewährleistet sein. Diese zusätzlichen Strukturen zur unfallsicheren Ausgestaltung der Hochvoltspeicher benötigen zum einen einen erhöhten Bauraum im Kraftfahrzeug, und erhöhen zum anderen die Produktions- und Montagekosten.High-voltage accumulators in motor vehicles are used in particular for driving hybrid vehicles or electric vehicles. According to the state of the art, high-voltage accumulators are protected with additional structures in the vehicle in order not to generate a safety-critical state in the event of a crash. In particular, even after an accident, the safety requirements z. B. the contact protection against the high-voltage components, be guaranteed. These additional structures for accident-proof design of the high-voltage storage require on the one hand an increased space in the motor vehicle, and on the other hand increase the production and assembly costs.
Es ist Aufgabe vorliegender Erfindung, einen Hochvoltspeicher für eine unfallsichere Montage in einem Kraftfahrzeug anzugeben, der bei kostengünstiger Produktion und Montage den Hochvoltspeicher ausreichend bei einem Unfall schützt.It is an object of the present invention to provide a high-voltage storage for accident-proof installation in a motor vehicle, which protects the high-voltage accumulator sufficiently in an accident at low cost production and assembly.
Die Aufgabe wird gelost durch die Merkmale der unabhängigen Ansprüche. Die abhängigen Ansprüche haben vorteilhafte Ausbildungen der Erfindung zum Gegenstand.The object is solved by the features of the independent claims. The dependent claims are advantageous embodiments of the invention to the subject.
So wird die Erfindung gelöst durch einen Hochvoltspeicher für eine unfallsichere Montage in einem Kraftfahrzeug, umfassend ein Gehäuse zur Aufnahmen von Energiespeicherzellen und zumindest eine mit dem Gehäuse verbundene Haltevorrichtung zum Befestigen des Hochvoltspeichers an einer Aufnahme, insbesondere einer Fahrzeugkarosserie, wobei das Gehäuse aus einem ersten Material mit erster Duktilität und die Haltevorrichtung aus einem zweiten Material mit zweiter Duktilität besteht, und wobei die erste Duktilität kleiner der zweiten Duktilität ist. Insbesondere wird für das Material des Gehäuses Aluminium-Druckguss und für das Material der Haltevorrichtung Stahl gewählt. Das Speichergehäuse aus Aluminium-Druckguss lässt beispielsweise bis zu 18% Dehnung zu. Dadurch kann ein Großteil der Risse und Löcher, die bei einem Unfall auftreten können, vermieden werden. Um jedoch Höchstbelastungen an den Befestigungspunkten zwischen dem Hochvoltspeicher und der Karosserie zu vermeiden, werden hier die erfindungsgemäßen Haltevorrichtungen mit einer noch größeren Duktilität eingesetzt. Diese Haltevorrichtungen dienen somit gleichzeitig als Deformationselemente und können über ihre geometrische Ausgestaltung bezüglich der Crash-Sicherheit optimiert werden. Durch die Verwendung von Gussmaterial für das Gehäuse können zahlreiche Funktionen, wie z. B. Befestigungspunkte, einteilig mit dem Gehäuse gestaltet werden. Dadurch entfallen zusätzliche Elemente, die separat an das Gehäuse zu befestigen wären. Durch die erfindungsgemäßen Haltevorrichtungen aus einem äußerst duktilen Material, beispielsweise Stahl, werden Belastungsspitzen abgefangen und somit das Gussgehäuse geschützt.Thus, the invention is achieved by a high-voltage accumulator for accident-proof mounting in a motor vehicle, comprising a housing for receiving energy storage cells and at least one holding device connected to the housing for fastening the high-voltage accumulator to a receptacle, in particular a vehicle body, wherein the housing of a first material with first ductility and the holding device made of a second material with second ductility, and wherein the first ductility is smaller than the second ductility. In particular, die-cast aluminum is selected for the material of the housing and steel for the material of the holding device. The storage housing made of die-cast aluminum allows for example up to 18% elongation. As a result, most of the cracks and holes that can occur in an accident can be avoided. However, in order to avoid maximum loads on the attachment points between the high-voltage accumulator and the body, the holding devices according to the invention are used here with an even greater ductility. These holding devices thus serve at the same time as deformation elements and can be optimized by their geometric configuration with respect to the crash safety. Through the use of cast material for the housing numerous functions, such. B. attachment points, be designed in one piece with the housing. This eliminates additional elements that would be attached separately to the housing. Due to the holding devices according to the invention of an extremely ductile material, such as steel, load peaks are intercepted and thus protected the cast housing.
Bevorzugt kommen folgende Materialpaarungen für das erste Material und das zweite Material zum Einsatz: Aluminium/Stahl, Aluminium-Druckguss/Stahl, Kunststoff/Metall, Kunststoff/Stahl, Kunststoff/Aluminium oder Kunststoff/Aluminium-Druckguss. Das jeweils erstgenannte Material wird für das Gehäuse verwendet, das andere Material für die Haltevorrichtung. Darüber hinaus kann das Gehäuse und/oder die Haltevorrichtung aus einem Verbundmaterial, insbesondere GFK oder CFK, bestehen. Das Verbundmaterial kann je nach Design verschiedenste Duktilitäten aufweisen. So ist z. B. auch ein Gehäuse aus Stahl mit der ersten Duktilität in Kombination mit einer Haltevorrichtung aus Verbundmaterial mit der zweiten Duktilität vorgesehen. Aber auch ein Gehäuse aus Verbundmaterial mit der ersten Duktilität in Kombination mit einer Haltevorrichtung aus Stahl mit der zweiten Duktilität, oder ein Gehäuse aus Verbundmaterial mit der ersten Duktilität in Kombination mit einer Haltevorrichtung aus Verbundmaterial mit der zweiten Duktilität sind möglich. Ausschlaggebend ist, dass die Haltevorrichtung als Deformationselement ausgebildet, wobei die Haltevorrichtung zur plastischen Verformung ausgelegt ist, um eine plastische Verformung des Gehäuses zu verhindern. Die beiden Bauteile müssen dabei nicht vollständig aus dem jeweiligen Material gefertigt werden, sondern bevorzugt nur im Wesentlichen aus dem jeweiligen Material bestehen.Preferably, the following material pairings are used for the first material and the second material: aluminum / steel, die-cast aluminum / steel, plastic / metal, plastic / steel, plastic / aluminum or plastic / die-cast aluminum. The former material is used for the housing, the other material for the holding device. In addition, the housing and / or the holding device may consist of a composite material, in particular GFK or CFK. Depending on the design, the composite material can have a wide variety of ductility. So z. For example, a steel housing having the first ductility is also provided in combination with a second ductility composite support. However, a first ductility composite housing in combination with a second ductility steel fixture, or a first ductility composite housing in combination with a second ductility composite fixture are also possible. The decisive factor is that the holding device is designed as a deformation element, wherein the holding device is designed for plastic deformation in order to prevent a plastic deformation of the housing. The two components need not be made completely from the respective material, but preferably only consist essentially of the respective material.
In besonders bevorzugter Ausführung ist vorgesehen, dass die Haltevorrichtung mit dem Gehäuse kraftschlüssig verbunden, insbesondere angeschraubt, ist. Alternativ wäre ein Vernieten oder Verschweißen oder ein Formschluss der Haltevorrichtung am Gehäuse denkbar. Ferner ist als Verbindung zwischen Gehäuse und Haltevorrichtung vorgesehen, dass die Haltevorrichtung, bevorzugt aus Metall, von dem Gehäuse aus Kunststoff umspritz ist.In a particularly preferred embodiment, it is provided that the holding device is non-positively connected to the housing, in particular screwed, is. Alternatively, a riveting or welding or a positive connection of the holding device on the housing would be conceivable. Furthermore, it is provided as a connection between the housing and the holding device, that the holding device, preferably made of metal, from the housing of plastic is encapsulated.
Des Weiteren sind zumindest zwei Schraubverbindungen zwischen dem Gehäuse und der Haltevorrichtung bevorzugt vorgesehen, wobei die zumindest zwei Schraubverbindungen nicht-parallel ausgerichtet sind. D. h., dass sich die beiden Schrauben bzw. die beiden Bolzen für die Schraubverbindung nicht parallel erstrecken. Insbesondere stehen die beiden Schraubverbindungen zwischen Gehäuse und Haltevorrichtung in einem 90°-Winkel zueinander. Der Winkel kann bis zu 20° in beide Richtungen abweichen.Furthermore, at least two screw connections between the housing and the holding device are preferably provided, wherein the at least two screw connections are aligned non-parallel. This means that the two screws or the two bolts for the screw connection do not extend parallel. In particular, the two screw connections between housing and holding device are at a 90 ° angle to each other. The angle can deviate up to 20 ° in both directions.
Darüber hinaus ist bevorzugt vorgesehen, dass die Haltevorrichtung zumindest drei Verbindungsebenen umfasst. Die Verbindungsebenen sind insbesondere als Verschraubungsebenen ausgebildet. Eine Verschraubungsebene ist eine Ebene an der Haltevorrichtung, die beispielsweise mit Löchern, Langlöchern oder Schlitzen für das Aufnehmen eines Bolzens oder einer Schraube ausgebildet ist. Alternativ kann auch eine Schraube oder ein Bolzen senkrecht von der Verschraubungsebene abstehen. Bevorzugt ist nun vorgesehen, dass zumindest zwei der drei Verbindungsebenen nicht-parallel sind. Die Haltevorrichtung ist somit durch ihre verschiedenen Verbindungsebenen als Haltewinkel ausgebildet.In addition, it is preferably provided that the holding device comprises at least three connection levels. The connection levels are designed in particular as Verschraubungsebenen. A Verschraubungsebene is a plane on the holding device, which is formed for example with holes, oblong holes or slots for receiving a bolt or a screw. Alternatively, a screw or a bolt can protrude perpendicularly from the screwing plane. It is now preferably provided that at least two of the three connection levels are non-parallel. The holding device is thus formed by their different connection levels as a bracket.
In besonders bevorzugter Ausführung ist dabei vorgesehen, dass jede der Verschraubungsebenen zumindest einen Durchbruch und/oder einen von der Verschraubungsebene abstehenden Bolzen umfasst. Die Durchbrüche bzw. die Bolzen werden zum Verbinden zwischen der jeweiligen Verschraubungsebene mit dem Gehäuse bzw. der Aufnahme (Fahrzeugkarosserie) genutzt.In a particularly preferred embodiment, it is provided that each of the bolting planes comprises at least one opening and / or a bolt protruding from the bolting plane. The openings or the bolts are used to connect between the respective Verschraubungsebene with the housing or the receptacle (vehicle body).
Bevorzugt ist die Haltevorrichtung als Deformationselement ausgebildet, wobei die Haltevorrichtung zur plastischen Verformung ausgelegt ist, um eine plastische Verformung des Gehäuses zu verhindern. Die Haltevorrichtung ist also derart ausgelegt das bei entsprechender Last auf den Hochvoltspeicher eine plastische Verformung der Haltevorrichtung erzeugt wird, wobei gleichzeitig das Gehäuse nur elastisch verformt wird. Bei der Haltevorrichtung ist bei Überlast auch eine Rissbildung oder ein Versagen zulässig.Preferably, the holding device is designed as a deformation element, wherein the holding device is designed for plastic deformation in order to prevent plastic deformation of the housing. The holding device is thus designed so that upon appropriate load on the high-voltage accumulator, a plastic deformation of the holding device is generated, wherein at the same time the housing is only elastically deformed. With the holding device, cracking or failure is also permissible in the event of overload.
Die Erfindung umfasst des Weiteren eine Anordnung, umfassend einen Hochvoltspeicher, wie er soeben beschrieben wurde, und eine Fahrzeugkarosserie als Aufnahme für den Hochvoltspeicher. Dabei ist die Haltevorrichtung zum einen mit dem Gehäuse des Hochvoltspeichers verbunden und zum anderen mit der Fahrzeugkarosserie. Die bereits beschriebenen vorteilhaften Ausgestaltungen des Hochvoltspeichers finden entsprechend bevorzugte Anwendung im Rahmen der erfindungsgemäßen Anordnung.The invention further includes an arrangement comprising a high-voltage accumulator as just described and a vehicle body as a receptacle for the high-voltage accumulator. The holding device is connected on the one hand to the housing of the high-voltage accumulator and the other with the vehicle body. The already described advantageous embodiments of the high-voltage accumulator find correspondingly preferred application in the context of the arrangement according to the invention.
Besonders bevorzugt ist vorgesehen, dass das Gehäuse auf der ersten Verbindungsebene der Haltevorrichtung aufliegt und, dass die Haltevorrichtung mit der dritten Verbindungsebene auf der Karosserie aufliegt. Gleichzeitig dienen dann auch die Verbindungsebenen zum Verschrauben der Haltevorrichtung mit dem Gehäuse bzw. mit der Fahrzeugkarosserie. Insbesondere sind die erste Verbindungsebene und die dritte Verbindungsebene im Wesentlichen parallel zueinander ausgerichtet. Auch eine Abweichung von 20° zueinander wird hier noch als parallel angesehen. Die zweite Verbindungsebene, welche eine Verschraubung zwischen Haltevorrichtung und Gehäuse vorsieht, steht im Wesentlichen senkrecht zur ersten Verbindungsebene und zur dritten Verbindungsebene. Auch hier ist ein Abweichen von 20° noch als senkrecht anzusehen.Particularly preferably, it is provided that the housing rests on the first connection plane of the holding device and that the holding device rests with the third connection plane on the body. At the same time then serve the connection levels for screwing the holding device to the housing or with the vehicle body. In particular, the first connection plane and the third connection plane are aligned substantially parallel to one another. Even a deviation of 20 ° to each other is still considered as parallel here. The second connection plane, which provides a screw connection between the holding device and the housing, is essentially perpendicular to the first connection plane and to the third connection plane. Again, a deviation of 20 ° is still considered perpendicular.
Des Weiteren ist bevorzugt vorgesehen, dass der Hochvoltspeicher zwei Haltevorrichtungen umfasst. Eine erste Haltevorrichtung ist dabei mit einem ersten Längsträger der Fahrzeugkarosserie verbunden und die zweite Haltevorrichtung befindet sich gegenüber und stellt die Verbindung zu einem zweiten Längsträger der Fahrzeugkarosserie dar. Der erfindungsgemäße Hochvoltspeicher hängt dadurch zwischen zwei Längsträgern der Fahrzeugkarosserie. Alternativ erfolgt die Befestigung einer oder beider Haltevorrichtungen an einer Fahrwerkskomponente.Furthermore, it is preferably provided that the high-voltage accumulator comprises two holding devices. A first holding device is connected to a first side member of the vehicle body and the second holding device is opposite and provides the connection to a second side member of the vehicle body. The high-voltage storage according to the invention depends thereby between two longitudinal members of the vehicle body. Alternatively, the attachment of one or both holding devices takes place on a chassis component.
