Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Rahmenbauteil dahingehend weiterzubilden, dass dessen Baugröße ohne Einbussen in der Crashsicherheit in einfacher Weise verringert werden kann. Des Weiteren soll ein Verfahren zu dessen Herstellung angegeben werden.Of the Invention is based on the object, a generic Frame component to the effect that its size reduced without sacrificing crash safety in a simple manner can be. Furthermore, a method for its production be specified.
Die Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruches 1 hinsichtlich des Rahmenbauteils und durch die Merkmale des Patentanspruches 5 hinsichtlich des Verfahrens gelöst.The Task is according to the invention by the features of claim 1 with respect to the frame member and by the Characteristics of claim 5 solved with respect to the method.
Aufgrund der Erfindung wird das Rahmenbauteil auf nur zwei Bauteile reduziert, wobei das eine Bauteil, das Versteifungsstrukturteil, im anderen Bauteil, also im Blechprofil aufgenommen ist, so dass die Baugröße des Rahmenbauteils zusätzlich verringert wird. Dies erbringt für die Insassen des Fahrzeugs eine verbesserte Übersicht des Verkehrs bzw. der äußeren Umgebung. Darüber hinaus gewährt es dem Fahrzeuginsassen eine größere Kopffreiheit, was sich bei einem Crash verletzungsmindernd auswirkt. Weiterhin werden durch den Entfall eines Bauteils und von Fügeelementen die Herstellung vereinfacht und der Kosten reduziert. Die Verringerung der Bauteilezahl ohne Erhöhung der Massivität der noch vorhandenen Bauteile ist in besonders hohem Masse dem Leichtbau zuträglich, was den Fahrzeugverbrauch und die Abgasemission absenkt. Trotz der Erreichung einer geringeren Baugröße ist die Steifigkeit des Rahmenbauteils unverändert, wenn nicht gar verbessert, da das Versteifungsstrukturteil die durch den Wegfall der schalenförmigen Hohlprofilstruktur entstandene Schwächung des Rahmenbauteils mehr als kompensiert. Hierbei kann das Versteifungsstrukturteil auch entgegen der bisher üblichen Bauweisen in einfacher Weise hinsichtlich seiner Versteifungseigenschaften speziell an die lokal anfallenden mechanischen Belastungen angepasst werden, so dass einerseits eine besonders hohe Crashsicherheit gegeben ist als auch der Einsatz von überschüssigem Material verhindert wird, was ebenfalls dem Leichtbau entgegenkommt und Materialressourcen schont. Zudem besteht des Versteifungsstrukturteil aus einem Leichtbauwerkstoff, was zusätzlich vorteilhaft für den Leichtbau des Gesamtfahrzeugs ist.by virtue of invention, the frame component is reduced to only two components, wherein the one component, the stiffening structure part, in the other component, So is included in the sheet metal profile, so that the size of the frame member is additionally reduced. This provides for the occupants of the vehicle an improved overview the traffic or the external environment. About that In addition, it gives the vehicle occupant a larger Headroom, which reduces injury in a crash. Furthermore, the elimination of a component and joining elements simplifies manufacturing and reduces costs. The reduction the number of components without increasing the massiveness The remaining components is particularly lightweight construction conducive to what the vehicle consumption and exhaust emission lowers. Despite achieving a smaller size the rigidity of the frame member is unchanged when Not even improved, since the stiffening structure part by the Elimination of the shell-shaped hollow profile structure resulting Weakening of the frame component more than compensated. in this connection can the stiffening structure part also contrary to the usual Structures in a simple manner with respect to its stiffening properties specially adapted to the local mechanical loads be so on the one hand given a particularly high crash safety is as well as the use of excess material is prevented, which also accommodates the lightweight construction and material resources spares. In addition, the stiffening structure part consists of a lightweight material, which additionally advantageous for the lightweight construction of the Whole vehicle is.
Das Versteifungsstrukturteil kann in einfacher Weise im Inneren des hutprofilförmigen Blechprofils angeordnet und dort an diesem in Abhängigkeit vom verwandten Material beispielsweise durch Kleben, Schweißen, Löten befestigt werden.The Stiffening structure part can be easily inside the hat profile-shaped sheet metal profiles arranged and there at this depending on the related material, for example be attached by gluing, welding, soldering.
Zur bevorzugten Herstellung des Rahmenbauteils wird ein unstrukturiertes Blech zu einem hutprofilförmigen Blechprofil tiefgezogen und anschließend in ein Spritzgießwerkzeug eingelegt, in dem an das Blechprofil in dessen Inneren das Versteifungsstrukturteil aus dem Leichtbauwerkstoff angespritzt wird. Während in Verbauungslage des Rahmenbauteils das Innere des Blechprofils zum Fahrzeuginnenraum hin gerichtet ist, bildet seine Außenseite mit einem Teilbereich die Sichtseite des Bauteils. Zur verbesserten Haftung des Spritzgießmaterials am Blechprofil ist es denkbar, dass das Blechprofil an Stellen, die im verbauten Zustand des Rahmenbauteils außerhalb des Sichtbereichs liegen, Durchtrittsöffnungen oder Durchzüge aufweist, durch die das Spritzgießmaterial hindurchtreten kann und beim Erstarren verschließt, wobei das hindurchgetretene Material einen Blindniet oder Zuganker bildet, mit dem das Versteifungsstrukturteil sich am Blechprofil festkrallt. Ebenfalls ist es denkbar, dass das Spritzgießmaterial das Blechprofil randseitig umgreift, wobei dies in Abschnitten des Blechprofils erfolgt, die außerhalb des Sichtbereichs liegen.to preferred manufacture of the frame component is an unstructured Deep-drawn sheet metal to a hat profile-shaped sheet metal profile and then inserted into an injection mold, in which on the sheet metal profile in the interior of the stiffening structure part is molded from the lightweight material. While in Verbauungslage of the frame member the interior of the sheet metal profile for Vehicle interior is directed, forms its outside with a partial area the visible side of the component. To the improved Adhesion of the injection molding material on the sheet metal profile, it is conceivable that the sheet metal profile in places that are in the installed state of the frame component lie outside the field of view, passages or passageways through which the injection molding material can pass through and closes when solidifying, wherein the material that has passed through forms a blind rivet or tie rod, with which the stiffening structure part clings to the sheet metal profile. It is also conceivable that the injection molding the Sheet metal edge engages around the edge, this in sections of the sheet metal profile takes place outside the field of view.
In einer besonders bevorzugten Weiterbildung der Erfindung nach Anspruch 2 weist das Blechprofil Formschlusselemente auf, mittels derer das Versteifungsstrukturteil mit dem Blechprofil formschlüssig verbunden ist. Hierdurch wird dem Versteifungsstrukturteil am Blechprofil ein besonders guter rutsch- und drehfester Halt gegeben. Hierzu werden die Formschlusselemente in bevorzugter Ausgestaltung nach Anspruch 6 im Tiefziehverfahren in Form von muldenartigen Vertiefungen und/oder Erhebungen ausgeformt, wonach die Formschlusselemente umspritzt werden. In besonders verfahrensökonomischer Weise kann dabei gleichzeitig das Versteifungsstrukturteil hergestellt werden und ohne Fügevorgang am Blechprofil unverrückbar festgesetzt werden.In a particularly preferred embodiment of the invention according to claim 2, the sheet metal profile on positive locking elements, by means of which the Stiffening structure part with the sheet metal profile form-fitting connected is. As a result, the stiffening structure part on the sheet metal profile a particularly good non-slip and rotationally stable grip given. For this If the form-locking elements in a preferred embodiment Claim 6 in the deep-drawing process in the form of trough-like depressions and / or raised elevations, after which the positive-fit elements encapsulated become. In a particularly process-economical way can while the stiffening structure part are produced at the same time and without joining process on sheet metal profile immovable be fixed.
In einer bevorzugten Weiterbildung der Erfindung nach Anspruch 3 befinden die Formschlusselemente sich an Stellen des Blechprofils, die im verbauten Zustand des Blechprofils außerhalb des Sichtbereichs liegen, wodurch die Ausbildung des Rahmenelements auch hohen optischen Ansprüchen genügen kann, da die auf Randstreifen des Profiltopfes angeordneten ansonsten sichtbaren Formschlusselemente von den sich anschließenden Blechen oder Blenden verdeckt werden. Weitere Formschlusselemente, die im Inneren des Profiltopfes angeordnet sind, sind ausschließlich an den Seitenwänden des Topfes ausgebildet, welche in Verbauungslage des Rahmenbauteils ebenfalls nicht sichtbar sind.In a preferred embodiment of the invention according to claim 3, the interlocking elements are located at locations of the sheet metal profile, which in the installed state of the sheet metal profile outside the Sichtbe Rich, whereby the formation of the frame member can also meet high optical demands, since the arranged on edge strips of the profile pot otherwise visible positive locking elements are covered by the subsequent sheets or panels. Other interlocking elements, which are arranged in the interior of the profile pot, are formed exclusively on the side walls of the pot, which are also not visible in Verbauungslage of the frame member.
In einer bevorzugten Weiterbildung der Erfindung nach Anspruch 4 beinhaltet das Versteifungsstrukturteil längs des Blechprofils und parallel zueinander verlaufende Lamellen, die mittels Querlamellen und Diagonallamellen miteinander verbunden sind. Diese Struktur ist sehr gewichts- und platzsparend und trotzdem erfüllt sie die hohen Steifigkeitsanforderungen. Außerdem wird die Verteilung der einwirkenden Kräfte bei einem Aufprall besser verteilt, was sich günstig auf den Insassenschutz auswirkt. Die Querlamellen und Diagonallamellen erbringen nicht nur eine Erhöhung der Steifigkeit für das Rahmenbauteil sondern stabilisieren auch die parallel zueinander laufenden versteifenden Lamellen und verhindern haltgebend, dass diese nicht aus den Formschlusselementen ausknüpfen. Zum sicheren Eingehen einer formschlüssigen Verbindung mit den besagten Formschlusselementen des Blechprofils ist es förderlich, seitlich abragende Haltelappen an die Lamellen anzuspritzen, welche Lappen dann den Formschluss eingehen. Alternativ können auch die Lamellen lokal dick genug gespritzt werden, damit Formschlusselement umfasst wird. Dies erfordert jedoch mehr Spritzgussmaterial als die erste Variante.In a preferred embodiment of the invention according to claim 4 includes the stiffening structure part along the sheet metal profile and mutually parallel lamellae, by means of transverse lamellae and diagonal louvers are connected together. This structure is very weight and space saving and still fulfilled They meet the high rigidity requirements. In addition, will the distribution of the forces acting in an impact better distributed, which is beneficial to occupant protection effect. The cross blades and diagonal blades do not provide only an increase in rigidity for the frame component but also stabilize the stiffening parallel to each other Slats and prevent holding that these are not from the form-locking elements ausknüpfen. For safely entering a form-locking Connection with the said positive locking elements of the sheet metal profile it is conducive to laterally projecting retaining tabs on the To inject fins, which lobes then enter the form fit. Alternatively, the lamellae can be locally thick enough sprayed are, so form-fitting element is included. However, this requires more Injection molding material as the first variant.
Eine Erhöhung der Versteifungswirkung des Versteifungsstrukturteils kann bevorzugt dadurch erzielt werden, dass das Spritzgießen parallel zum Blechprofil erfolgt. Hierzu wird vorab das Spritzgießmaterial mit Fasermaterial, beispielsweise Glasfasern oder Karbonfasern durchsetzt, so dass mit dem eindimensionalen Spritzgießen den Fasern eine Vorzugsrichtung gegeben wird, die den Widerstand des Versteifungsstrukturbauteils und damit des Rahmenteils gegenüber Biegung begünstigt.A Increasing the stiffening effect of the stiffening structure part can preferably be achieved by injection molding takes place parallel to the sheet metal profile. For this purpose, the injection molding material is in advance interspersed with fiber material, for example glass fibers or carbon fibers, so that with the one-dimensional injection molding the fibers a preferred direction is given that the resistance of the stiffening structure component and thus the frame part against bending favors.
Bevorzugt wird hierbei ein Gießmaterial mit der Bezeichnung BKV 60 EF (Polyamid mit einem hohen Glasfaseranteil von etwa 60%) verwandt. Mit diesem Material ist es zudem möglich, die Schmelzetemperatur und den Spritzdruck zu verringern, wodurch geringere Anforderungen an das Gießwerkzeug und den Druckerzeuger gestellt werden, was den Einsatz von einfacheren preisgünstigeren Materialien und Vorrichtungskonstruktionen für die Herstellung nach sich zieht.Prefers Here is a casting material with the name BKV 60th EF (polyamide with a high glass fiber content of about 60%) related. It is also possible with this material, the melt temperature and to reduce the injection pressure, thereby reducing requirements be placed on the casting tool and the pressure generator, which makes the use of simpler cheaper materials and device constructions for manufacturing pulls.
In einer weiteren besonders bevorzugten Weiterbildung nach Anspruch 9 wird der Leichtbauwerkstoff mittels Schaumspritzgießen angespritzt, wodurch sich hinsichtlich der Leichtbautechnik große Vorteile ergeben, wobei zusätzlich die Steifigkeit des Spritzgusselementes durch die mikrozelluläre Ausprägung des erstarrten Schaumes besonders groß ist und dadurch die Crashsicherheit noch weiter verbessert wird.In Another particularly preferred embodiment according to claim 9, the lightweight material by foam injection molding injection-molded, resulting in great advantages in terms of lightweight construction technology result, in addition, the rigidity of the injection molding element by the microcellular expression of the frozen Foam is particularly large and thus the crash safety is further improved.
Bei einer weiteren bevorzugten Ausgestaltung der Erfindung nach Anspruch 10 wird das Blechprofil vor dem Anspritzen mit einem dem Leichtbauwerkstoff ähnlichen oder entsprechenden Werkstoff beschichtet. Beim Anspritzen wird die Beschichtung teilweise aufgeschmolzen, wodurch sich durch die Materialähnlichkeit bzw. -gleichheit des Beschichtungswerkstoffs und des angespritzten Leichtbauwerkstoffs eine stoffschlüssige Verbindung ergibt, die den Halt des Versteifungsstrukturbauteils am Blechprofil noch weiter verbessert.at a further preferred embodiment of the invention according to claim 10, the sheet metal profile is similar to the lightweight material prior to injection molding or corresponding material coated. When molding is the coating partially melted, resulting in the material similarity or equality of the coating material and the molded Lightweight material gives a cohesive connection, which still holds the stiffening structure component on the sheet metal profile further improved.
Bei einer weiteren bevorzugten Ausgestaltung der Erfindung nach Anspruch 11 wird der Leichtbauwerkstoff mit dem Blechprofil verklebt. Die Verklebung kann alternativ oder zusätzlich zur formschlüssigen Verbindung erfolgen. Hierbei wird das Blechprofil mit einer Kleberschicht versehen, die entweder bei Normalbedingungen, also Raumtemperatur und Atmosphärendruck bereits klebende Eigenschaften aufweist oder erst zu einem späteren Zeitpunkt thermisch aktivierbar ist. Dies kann beispielsweise vorteilhaft durch die Abwärme des angespritzten heißen Leichbauwerkstoffes verursacht werden. Durch die Verklebung ergibt sich ein sehr guter Halt des Versteifungsstrukturbauteils am Blechprofil, bzw. der Halt wird noch verbessert, wenn sich zwischen den beiden Bauteilen auch eine formschlüssige Verbindung ausbildet.at a further preferred embodiment of the invention according to claim 11, the lightweight material is glued to the sheet metal profile. The Bonding may alternatively or in addition to the positive Connection done. Here, the sheet metal profile with an adhesive layer provided either at normal conditions, ie room temperature and atmospheric pressure already has adhesive properties or thermally activated at a later time is. This can be advantageous, for example, by the waste heat caused by the injected hot light construction material become. The bonding results in a very good hold of the Stiffening structure component on the sheet metal profile, or the stop is even better, if between the two components also a form-fitting connection is formed.
