Description
Die Erfindung betrifft ein Batteriegehäuseteil für eine Traktionsbatterie eines Fahrzeuges.The invention relates to a battery housing part for a traction battery of a vehicle.
Es ist bekannt, zur Anordnung von Traktionsbatterien in Fahrzeugen, die einen elektromotorischen Antrieb aufweisen, Batteriegehäuseteile einzusetzen. Diese können als Batterieschale, Batteriewanne, Batterietrog oder Batteriebox ausgebildet sein. Den Batteriegehäuseteilen ist gemeinsam, dass diese einen Aufnahmekörper ausbilden, innerhalb dem die Traktionsbatterie angeordnet ist. Dem Aufnahmekörper kommt hierbei die Funktion zu, die Traktionsbatterie sicher und definiert im Fahrzeug anzuordnen. Darüber hinaus muss das Batteriegehäuseteil die Traktionsbatterie im Crashfall vor mechanischen Einflüssen schützen.It is known to use battery housing parts for the arrangement of traction batteries in vehicles which have an electric motor drive. These can be designed as a battery tray, battery tray, battery tray or battery box. The battery housing parts have in common that they form a receiving body, within which the traction battery is arranged. The receiving body is here the function to arrange the traction battery safely and defined in the vehicle. In addition, the battery housing part must protect the traction battery in the event of a crash from mechanical influences.
Bekannt ist, derartige Batteriegehäuseteile aus ebenen, gekanteten oder tiefgezogenen Metallblechen zu bilden. It is known to form such battery housing parts from flat, folded or deep-drawn metal sheets.
Ferner ist bekannt, Batteriegehäuseteile aus einem Kunststoffmaterial zu bilden, da sich so Gewichtseinsparungen gegenüber metallischen Gehäuseteilen erzielen lassen. It is also known to form battery housing parts made of a plastic material, as can be achieved weight savings compared to metallic housing parts.
Schließlich sind aus
Der Erfindung liegt daher die Aufgabe zugrunde, ein Batteriegehäuseteil der gattungsgemäßen Art zu schaffen, das sich durch eine erhöhte Steifigkeit auszeichnet. The invention is therefore an object of the invention to provide a battery housing part of the generic type, which is characterized by an increased rigidity.
Erfindungsgemäß wird diese Aufgabe durch ein Batteriegehäuseteil mit denen in Anspruch 1 genannten Merkmalen gelöst. Dadurch, dass eine Organoblechkomponente des Batteriegehäuseteiles einen Bodenabschnitt und wenigstens einen senkrecht zum Bodenabschnitt verlaufenden Versteifungsabschnitt aufweist, wird vorteilhaft möglich, neben einer mechanischen Stabilisierung des Batteriegehäuseteiles gleichzeitig die Steifigkeit des Batteriegehäuseteiles weiter zu erhöhen. Die Versteifungsabschnitte, die senkrecht zum Bodenabschnitt verlaufen, können in x- und/oder y-Richtung eines Fahrzeuges verlaufen und so entweder in Fahrzeuglängsachse oder Fahrzeugquerachse angreifende Kräfte an das Batteriegehäuseteil abfangen. Die in dem Batteriegehäuseteil angeordnete Traktionsbatterie wird so besser vor mechanischer Zerstörung im Crashfall geschützt. According to the invention this object is achieved by a battery housing part with those mentioned in claim 1 features. The fact that an organo-sheet component of the battery-housing part has a bottom section and at least one stiffening section extending perpendicular to the bottom section advantageously makes it possible to further increase the rigidity of the battery-housing part in addition to mechanical stabilization of the battery-housing part. The stiffening sections, which run perpendicular to the bottom section, can extend in the x and / or y direction of a vehicle and thus intercept forces acting on the battery housing part either in the vehicle longitudinal axis or vehicle transverse axis. The arranged in the battery housing part traction battery is better protected against mechanical damage in the event of a crash.
In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass der Bodenabschnitt und der Versteifungsabschnitt der Organoblechkomponente einstückig von einem entsprechend geformten Organoblech gebildet sind. Hierdurch wird möglich, die Organoblechkomponente in einfacher Weise durch einen entsprechenden Umformschritt aus einem flächig vorliegenden Organoblech zu erzielen. In a preferred embodiment of the invention it is provided that the bottom portion and the stiffening portion of the organo-sheet component are integrally formed by a correspondingly shaped organo sheet. This makes it possible to achieve the organo-sheet component in a simple manner by means of a corresponding shaping step from a sheet of sheet-metal which is present in the form of a sheet.
In weiterer bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass der Versteifungsabschnitt von einem Rand des Aufnahmekörpers in Richtung einer Mitte des Aufnahmekörpers sich konisch verjüngt. Hierdurch wird vorteilhaft erreicht, dass in den Bereichen, in denen eine Kraft zuerst angreift, der Versteifungsabschnitt seine größte räumliche Ausdehnung hat. Zur Mitte des Aufnahmekörpers nimmt der Versteifungsabschnitt keinen zusätzlichen Bauraum ein, der zur Anordnung der Traktionsbatterie zur Verfügung steht. In a further preferred embodiment of the invention it is provided that the stiffening section tapers conically from an edge of the receiving body in the direction of a center of the receiving body. This advantageously achieves that in the areas in which a force acts first, the stiffening section has its greatest spatial extent. To the center of the receiving body of the stiffening section takes no additional space, which is available for the arrangement of the traction battery.
Darüber hinaus ist in bevorzugter Ausgestaltung der Erfindung vorgesehen, dass der Versteifungsabschnitt sich in der Mitte des Aufnahmekörpers an einem am Boden des Aufnahmekörpers ausgebildeten Tunnel abstützt. Hierdurch wird eine in den Versteifungsabschnitt eingeleitete Kraft flächig in ein abstützenden Tunnel eingeleitet, so dass ein verbesserter Kraftfluss und dadurch besonders hohe Steifigkeit gegeben ist. In addition, it is provided in a preferred embodiment of the invention that the stiffening portion is supported in the middle of the receiving body on a trained at the bottom of the receiving body tunnel. As a result, a force introduced into the stiffening section is introduced in a planar manner into a supporting tunnel, so that an improved force flow and thus particularly high rigidity is achieved.
Darüber hinaus ist in bevorzugter Ausgestaltung der Erfindung vorgesehen, dass der Bodenabschnitt sich nur teilweise über den gesamten Boden des Aufnahmekörpers erstreckt. Hierdurch wird vorteilhaft möglich, den Bodenabschnitt nur soweit auszubilden, dass der Versteifungsabschnitt sicher in dem Aufnahmekörper positioniert wird. Die Gesamtgröße der Organoblechkomponente wird hierdurch gering gehalten, so dass das gesamte Gewicht des Batteriegehäuseteiles minimiert wird. In addition, it is provided in a preferred embodiment of the invention that the bottom portion extends only partially over the entire bottom of the receiving body. This advantageously makes it possible to form the bottom section only to the extent that the stiffening section is securely positioned in the receiving body. The overall size of the organo-sheet component thereby becomes kept small, so that the total weight of the battery housing part is minimized.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.
Die verschiedenen in dieser Anmeldung genannten Ausführungsformen der Erfindung sind, sofern im Einzelfall nicht anders ausgeführt, mit Vorteil miteinander kombinierbar.The various embodiments of the invention mentioned in this application are, unless otherwise stated in the individual case, advantageously combinable with each other.
