Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Halten einer Batterie in einer Tragstruktur einer Karosserie eines Fahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for holding a battery in a support structure of a body of a vehicle according to the preamble of patent claim 1.
Bei der Entwicklung von Hybridfahrzeugen oder reinen Elektrofahrzeugen ist ein geeigneter Weg erforderlich, die Batterie bzw. Traktionsbatterie in geeigneter Weise an die Karosseriestruktur anzubinden. Soll die Batterie als Montagelösung von unten in die Fahrzeugkarosserie eingebaut werden, so wird eine steife Montageplatte benötigt, welche die Gewichtskräfte von der Batterie in die Karosserie leitet. In aktuellen Batteriekonzepten werden die Batteriezellen über Aluminiumplatten gekühlt, welche sich in der Regel am Fuß der Zellen befinden. Man benötigt somit unterhalb der Batteriezellen eine separate Kühlplatte und zusätzlich eine Montageplatte. Darüber hinaus wird eine thermische Isolation gegenüber der Fahrzeugumgebung benötigt, um den Kühlaufwand möglichst gering zu halten. Da die Kühlplatten derzeit massive Aluminiumplatten sind und die Montageplatte durch die hohen Batteriegewichte sehr steif ausgeführt werden muss, befinden sich zwei schwere Strukturen im Fahrzeug, welche prinzipiell ähnliche physikalische Eigenschaften haben. Zusätzlich wird die thermische Isolation üblicherweise über ein separates Bauteil dargestellt, wodurch zusätzliches Gewicht hinzukommt.In the development of hybrid vehicles or pure electric vehicles, a suitable way is required to connect the battery or traction battery in a suitable manner to the body structure. If the battery is to be installed as a mounting solution from below into the vehicle body, so a stiff mounting plate is needed, which directs the weight forces from the battery into the body. In current battery concepts, the battery cells are cooled by aluminum plates, which are usually located at the bottom of the cells. It thus requires below the battery cells a separate cooling plate and in addition a mounting plate. In addition, a thermal insulation against the vehicle environment is needed to keep the cooling costs as low as possible. Since the cooling plates are currently massive aluminum plates and the mounting plate must be made very stiff by the high battery weights, there are two heavy structures in the vehicle, which in principle have similar physical properties. In addition, the thermal insulation is usually represented by a separate component, adding additional weight.

Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zum Halten einer Batterie in einer Tragstruktur einer Karosserie eines Fahrzeugs derart auszugestalten, dass eine gewichtsoptimierte Anbindung der Batterie an die Tragstruktur der Fahrzeugkarosserie möglich ist.The invention is based on the object, a device for holding a battery in a support structure of a body of a vehicle in such a way that a weight-optimized connection of the battery to the support structure of the vehicle body is possible.
Erfindungsgemäß wird die Aufgabe durch Bereitstellung einer Vorrichtung zum Halten einer Batterie in einer Tragstruktur einer Karosserie eines Fahrzeugs mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausführungsformen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.According to the invention the object is achieved by providing a device for holding a battery in a support structure of a body of a vehicle with the features of claim 1. Advantageous embodiments and further developments of the invention are specified in the dependent claims.
Um eine Vorrichtung zum Halten einer Batterie in einer Tragstruktur einer Karosserie eines Fahrzeugs derart auszugestalten, dass eine gewichtsoptimierte Anbindung der Batterie an die Tragstruktur der Fahrzeugkarosserie möglich ist, ist die Halteeinrichtung erfindungsgemäß mehrschichtig ausgebildet. In vorteilhafter Weise ergibt sich hierdurch ein Sandwichbauteil bzw. eine Sandwichstruktur, dessen bzw. deren Schichten an unterschiedliche Belastungsfälle bzw. Anwendungsfälle anpassbar sind. In vorteilhafter Weise können die Schichten beispielsweise derart ausgelegt werden, dass diese eine hohe Steifigkeit bei geringem Gewicht, eine hohe thermische und akustische Isolation, eine hohe Energieabsorption, ein hohes Dämpfungsvermögen und/oder eine hohe Oberflächengüte bei niedrigen Herstellungskosten aufweisen.In order to design a device for holding a battery in a support structure of a body of a vehicle such that a weight-optimized connection of the battery to the support structure of the vehicle body is possible, the holding device according to the invention is formed multi-layered. Advantageously, this results in a sandwich component or a sandwich structure whose or their layers are adaptable to different load cases or applications. For example, the layers may advantageously be designed such that they have a high stiffness with low weight, a high thermal and acoustic insulation, a high energy absorption, a high damping capacity and / or a high surface quality with low production costs.
In vorteilhafter Ausgestaltung der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die Halteeinrichtung als Sandwichbauteil mit einer plattenartigen Oberschicht, einer plattenartigen Unterschicht und einer zwischen der Oberschicht und der Unterschicht angeordneten Energieabsorptionsschicht ausgebildet ist. Mit einem derartigen Aufbau lässt sich eine besonders vorteilhafte Energieabsorption erreichen, da mittels der Energieabsorptionsschicht der plattenartigen Halteeinrichtung eine besonders vorteilhafte Energieabsorption in Verbindung mit aufprallbedingten Krafteinleitungen möglich wird, welche das Crashverhalten des Kraftfahrzeugs positiv beeinflussen. Des Weiteren bildet eine derartige mehrschichtige bzw. mehrlagige, plattenartige Halteeinrichtung auch einen besonders vorteilhaften Schutz für die darüber liegende Batterie aus, da es beispielsweise in Verbindung mit so genannten „Aufsetzern” des Kraftfahrzeugs auf die Fahrbahn aufgrund der Energieabsorption durch die Halteeinrichtung regelmäßig lediglich zu einer Verformung der Halteeinrichtung kommt, so dass die auftretenden Kräfte gewissermaßen nicht bis zur Karosseriestruktur durchschlagen. Des Weiteren kann mit einem derartigen Sandwichbauteil auch das Eigenschwingverhalten der Tragstruktur in positiver Weise beeinflusst werden.In an advantageous embodiment of the device according to the invention, it is provided that the holding device is designed as a sandwich component with a plate-like upper layer, a plate-like lower layer and an energy absorption layer arranged between the upper layer and the lower layer. With such a structure, a particularly advantageous energy absorption can be achieved, since by means of the energy absorption layer of the plate-like holding device a particularly advantageous energy absorption in conjunction with impact-induced force transmission is possible, which positively influence the crash behavior of the motor vehicle. Furthermore, such a multilayer or multi-layer, plate-like holding device also forms a particularly advantageous protection for the overlying battery, since it regularly only for example in connection with so-called "Aufsetzern" of the motor vehicle on the road due to the energy absorption by the holding device Deformation of the holding device comes, so that the forces do not penetrate to a certain extent to the body structure. Furthermore, with such a sandwich component, the natural vibration behavior of the support structure can also be influenced in a positive manner.
In weiterer vorteilhafter Ausgestaltung der erfindungsgemäßen Vorrichtung ist vorgesehen, dass zumindest die der Batterie zugewandte Oberschicht als Kühleinrichtung ausgebildet ist. Bevorzugt weist die Oberschicht zur Ausbildung der Kühleinrichtung mindestens einen Kühlkanal auf. In vorteilhafter Weise ist hierdurch die Funktion einer separaten Kühlplatte zur Kühlung der Batterie in die Halteeinrichtung bzw. in die Oberschicht des Sandwichbauteils integriert. Da ein Sandwichbauteil auf Grund seines Aufbaus üblicherweise eine gute bzw. hohe thermische Isolation aufweist, kann auf eine separate Isolierung verzichtet werden, wodurch wiederum sowohl Gewicht als auch Kosten eingespart werden können. Durch die Integration der Kühlfunktionen in die Oberschicht bzw. in die obere Sandwichhaut der Halteeinrichtung wird eine Dopplung von Bauteilen mit prinzipiell ähnlichen physikalischen Eigenschaften vermieden, was zu einer Gewichtsreduzierung führt. Zusätzlich entfällt die Verbindungstechnik, welche bei einer separaten Kühlplatte zwischen dieser und der Montageplatte bzw. der Halteeinrichtung erforderlich ist. Dies bedeutet eine weitere Gewichtsreduzierung. Da die Verbindungsstellen eine Schwachstelle im Vergleich zu einer integrierten Lösung bzw. einer Sandwichlösung darstellen, wird auch die Funktion in Bezug auf eine steife Anbindung der Batterie an die Karosserie verbessert. Die Sandwichkonstruktion vereint somit Kühlfunktion, Haltefunktion und Isolationsfunktion für eine Batterie eines Fahrzeugs.In a further advantageous embodiment of the device according to the invention it is provided that at least the upper layer facing the battery is designed as a cooling device. The upper layer preferably has at least one cooling channel for forming the cooling device. Advantageously, this is the function of a separate cooling plate for cooling the battery in the holding device or in the upper layer of the sandwich component integrated. Since a sandwich component due to its structure usually has a good or high thermal insulation, can be dispensed with a separate insulation, which in turn can be saved both weight and cost. By integrating the cooling functions in the upper layer or in the upper sandwich skin of the holding device, a doubling of components with fundamentally similar physical properties is avoided, which leads to a reduction in weight. In addition, eliminates the connection technique, which is required for a separate cooling plate between this and the mounting plate or the holding device. This means a further weight reduction. Since the joints represent a weak point compared to an integrated solution or a sandwich solution, the function is also improved with respect to a rigid connection of the battery to the body. The sandwich design thus combines cooling function, holding function and insulation function for a battery of a vehicle.
In weiterer vorteilhafter Ausgestaltung der erfindungsgemäßen Vorrichtung weist die Oberschicht und/oder die Unterschicht eine hohe Steifigkeit auf. In vorteilhafter Weise genügt die Halteeinrichtung hierdurch den Anforderungen hinsichtlich der Steifigkeit insbesondere bei einer Montagelösung, bei welcher die Batterie von unten in die Fahrzeugkarosserie eingebaut werden soll, da hierbei eine steife Halteeinrichtung als Montageplatte benötigt wird, welche die Gewichtskräfte von der Batterie in die Karosserie leitet.In a further advantageous embodiment of the device according to the invention, the upper layer and / or the lower layer has a high rigidity. Advantageously, the holding device thereby meets the requirements in terms of rigidity, especially in a mounting solution in which the battery is to be installed from below into the vehicle body, since in this case a rigid holding device is required as a mounting plate, which directs the weight forces of the battery in the body ,
Der Aufbau der Halteeinrichtung als Sandwichbauteil ist insbesondere im Hinblick auf ein extrem leichtes und damit gewichtsgünstig aufgebautes Tragstrukturbauteil so dimensioniert, dass die Oberschicht und die Unterschicht eine gegenüber der Schichtstärke der Energieabsorptionsschicht dünnere Wandstärke aufweisen.The structure of the holding device as a sandwich component is dimensioned, in particular with regard to an extremely lightweight and thus low-weight structured support structure component, such that the upper layer and the lower layer have a thinner wall thickness than the layer thickness of the energy absorption layer.
In weiterer vorteilhafter Ausgestaltung der erfindungsgemäßen Vorrichtung besteht die Energieabsorptionsschicht aus einem elastischen Material oder Materialverbund. Besonders bevorzugt ist die Energieabsorptionsschicht als Hohlraumstruktur ausgebildet, welche in Verbindung mit den flächigen Deckschichten besonders günstige Energieabsorptionseigenschaften aufweist. Die Hohlraumstruktur ist bevorzugt gleichmäßig ausgebildet, beispielsweise in Verbindung mit sechseckförmigen Waben. Die Energieabsorptionsschicht kann jedoch grundsätzlich auch durch einen Energieabsorptionsschaum gebildet werden. Ein weiterer wesentlicher Vorteil einer derartigen Hohlraumstruktur als Energieabsorptionsschicht besteht darin, dass die Hohlraumstruktur zusammen mit den vorgesehenen Deckschichten, bevorzugt einer Oberschicht und einer Unterschicht, in Leichtbauweise, beispielsweise aus einem Leichtmetallwerkstoff und/oder einem Kunststoff bzw. Kunststoffverbund hergestellt werden kann, so dass sich ein extrem leichter Aufbau der Halteeinrichtung bei gleichzeitig hoher Steifigkeit erzielen lässt. Als Leichtbauwerkstoff für das Sandwichbauteil eignet sich insbesondere Aluminium. Zudem können in vorteilhafter Weise Kunststoffe bzw. Verbundwerkstoffe, insbesondere faserverstärkte Kunststoffe und/oder kohlefaserverstärkte Verbundwerkstoffe als Leichtbauwerkstoffe verwendet werden.In a further advantageous embodiment of the device according to the invention, the energy absorption layer consists of an elastic material or composite material. Particularly preferably, the energy absorption layer is formed as a cavity structure, which has particularly favorable energy absorption properties in connection with the flat cover layers. The cavity structure is preferably uniform, for example in connection with hexagonal honeycombs. However, the energy absorption layer can basically also be formed by an energy absorption foam. Another essential advantage of such a cavity structure as an energy absorption layer is that the cavity structure can be produced together with the provided cover layers, preferably a top layer and a bottom layer, in lightweight construction, for example of a light metal material and / or a plastic or plastic composite, so that an extremely lightweight construction of the holding device can achieve at the same time high rigidity. As a lightweight material for the sandwich component is particularly suitable aluminum. In addition, plastics or composite materials, in particular fiber-reinforced plastics and / or carbon fiber-reinforced composite materials can be used as lightweight materials in an advantageous manner.
In weiterer vorteilhafter Ausgestaltung der erfindungsgemäßen Vorrichtung ist die Halteeinrichtung über eine mechanische Verbindung lösbar an der Tragstruktur der Karosserie des Fahrzeugs festlegbar. Um die Montage bzw. Demontage von Bauteilen an der Tragstruktur zu ermöglichen, ist es vorteilhaft, dass die Halteeinrichtung lösbar an der Tragstruktur der Karosserie des Fahrzeugs festgelegt ist. Diese Festlegung erfolgt vorzugsweise mittels mehrerer Schraubverbindungen, wozu an der Halteeinrichtung eine vorgegebene Anzahl von Schraubenaufnahmelöchern ausgebildet ist. Diesen Schraubenaufnahmelöchern ist dann an der Tragstruktur wiederum jeweils ein Schraubenaufnahmeloch oder ein Schraubpunkt mit Schraubenmutter zugeordnet, in welche die Befestigungsschrauben zur lösbaren Festlegung der Halteeinrichtung an der Tragstruktur vorzugsweise von der Unterschichtseite her einschraubbar sind. Eine derartige lösbare Festlegung mittels Schraubverbindungen ist besonders einfach und auch funktionssicher herzustellen.In a further advantageous embodiment of the device according to the invention, the holding device via a mechanical connection is releasably secured to the support structure of the body of the vehicle. In order to enable the assembly or disassembly of components on the support structure, it is advantageous that the holding device is releasably fixed to the support structure of the body of the vehicle. This determination is preferably carried out by means of a plurality of screw connections, for which purpose a predetermined number of screw receiving holes is formed on the holding device. These screw receiving holes is then assigned to the support structure in turn in each case a screw receiving hole or a screw with nut, into which the mounting screws for releasably securing the holding device to the support structure are preferably screwed from the lower layer side. Such a detachable fixing by means of screw is particularly simple and reliable to produce.
