Abstract

The plate blank(1) comprises at least one additional tailored blank(5) which is welded on the end face by a transverse welded seam(8) to the plate section formed from the side sections(2,3) and the middle section(4). The additional tailored blanks form the source material for the front area of the floor plate. The additional blanks and other plate sections are joined by laser welding or resistance welding.

Description

Die Erfindung betrifft eine aus maßgeschneiderten Einzelplatinen, sogenannten tailored blanks, zusammengesetzte Platine für ein Fahrzeug-Bodenblech entsprechend dem Ober­ begriff des Patentanspruchs 1. Dabei sind die Einzelplatinen hinsichtlich der Blechdicken, der Materialqualitäten und der Oberflächenbeschaffenheit auf die spätere Beanspruchung abgestimmt, was sich positiv insbesondere auf das Gewicht des fertigen Bauteils, im vorlie­ genden Fall also des Bodenblechs, auswirkt.The invention relates to a made of tailored single boards, so-called tailored blank, assembled circuit board for a vehicle floor panel according to the upper Concept of patent claim 1. The individual boards with regard to the sheet thicknesses, the material qualities and the surface quality to the later stress coordinated, which has a positive effect in particular on the weight of the finished component case of the floor panel.

Ein gattungsgemäßes Bodenblech bekannter Art besteht aus drei Einzelplatinen, nämlich zwei Seitenteilen und einem zur Bildung des Tunnels bestimmten Mittelteil, die in zwei im wesentlichen in Längsrichtung verlaufenden Schweißnähten miteinander zu einer Mehr­ fachplatine verbunden worden sind, bevor aus dieser durch eine Umformoperation, z. B. durch Tiefziehen, das Bodenblech entstand.A generic floor panel of known type consists of three individual boards, namely two side parts and a central part intended to form the tunnel, which in two in essentially longitudinal weld seams with each other to a more compartment board have been connected before from this by a forming operation, for. B. by deep drawing, the floor panel was created.

Die Aufgabe der Erfindung besteht darin, das vorgenannte Bodenblech hinsichtlich seiner Beanspruchung wie Biegung, Torsion und belastungsgerechter Steifigkeit - insbesondere im Crashfall - zu verbessern. Es hat sich nämlich in Versuchsreihen herausgestellt, daß der vordere Bereich des Bodenblechs, also der Fußraum für Fahrer und Beifahrer, anderen Belastungen ausgesetzt ist als der übrige Bereich. So wie man bereits das bekannte Bodenblech aus Einzelplatinen für die Seitenteile und den Tunnel zusammengesetzt hat, die sich nicht nur in ihren Abmessungen einschließlich der Blechdicke, sondern auch in der Werkstoffgüte und der Oberflächenbehandlung unterscheiden beziehungsweise unterschei­ den können, so ist es auch zweckmäßig, das Bodenblechvorderteil erfindungsgemäß als separate Einzelplatine einzubringen und sie gemäß dem kennzeichnenden Teil des Patent­ anspruchs 1 mit der Platine zu verbinden.The object of the invention is the aforementioned floor panel with regard to its Stress such as bending, torsion and rigidity appropriate to the load - especially in Crash case - to improve. It has been shown in series of tests that the front area of the floor panel, i.e. the footwell for driver and front passenger, others Is more exposed than the rest of the area. Just like you already know Bottom plate composed of individual boards for the side parts and the tunnel that not only in their dimensions including the sheet thickness, but also in the Differentiate or differentiate between material quality and surface treatment that can, it is also appropriate, the floor panel front part according to the invention as separate separate board and insert them according to the characterizing part of the patent to connect claim 1 to the board.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung nachfolgend näher erläu­ tert. Darin zeigenAn embodiment of the invention is explained in more detail below with reference to the drawing tert. Show in it

Fig.Fig.

1 in Draufsicht eine aus vier Einzelplatinen zusammengeschweißte Platine für einen Fahrzeugboden und1 a top view of a circuit board welded together from four individual circuit boards for one Vehicle floor and

Fig. 2 den aus der Platine in Fig. 1 durch Umformung gewonnenen Fahrzeugboden in perspektivischer, verkleinerter Darstellung. Fig. 2 shows the vehicle floor obtained from the circuit board in Fig. 1 by deformation in a perspective, reduced view.

Die mit 1 bezeichnete Platine besteht aus den beiden Seitenteilplatinen 2, 3, der Tunnelpla­ tine 4 und der Fußraumplatine 5. Die Einzelplatinen 2 bis 4 sind in bekannter Weise in den in Längsrichtung verlaufenden Schweißnähten 6, 7 miteinander zu einer Teilplatine ver­ schweißt, beispielsweise im Laserschweißverfahren. In einem weiteren Arbeitsgang wird an diese Teilplatine die Fußraumplatine 5 angeschweißt, wobei die zugehörige Schweißnaht 8 zumindest annähernd senkrecht zu den Schweißnähten 6, 7 verläuft. Die Fußraumplatine 5 entspricht in ihrer Dickenabmessung und ihrer Materialqualität den späteren Belastungen speziell für diesen Bereich, insbesondere im Crashfall, denn diese unterscheiden sich bei Auslegung der Bauteile im Hinblick auf eine Gewichtsminimierung in der Regel deutlich von denen der Fußbodenseitenteile und des Tunnels.The board labeled 1 consists of the two side part boards 2 , 3 , the tunnel board 4 and the footwell board 5th The individual boards 2 to 4 are in a known manner in the longitudinally extending welds 6 , 7 welded together to a sub-board ver, for example in the laser welding process. In a further operation, the footwell board 5 is welded onto this sub-board, the associated weld 8 running at least approximately perpendicular to the welds 6 , 7 . The footwell board 5 corresponds in its thickness dimension and material quality to the later loads especially for this area, especially in the event of a crash, because these generally differ significantly from those of the floor side parts and the tunnel when designing the components with a view to minimizing weight.

In Fig. 2 sind die den Einzelplatinen in Fig. 1 entsprechenden, jetzt verformten Teile durch einen hinzugefügten Kopfzeiger bezeichnet.In Fig. 2, the now deformed parts corresponding to the single boards in Fig. 1 are designated by an added head pointer.
