Description
Die
Erfindung liegt auf dem Gebiet der Fahrzeugklimatisierung durch
gezielte Luftzufuhr bzw. Luftabfuhr, insbesondere mittels eines
Gebläses und/oder
einer Klimatisierungsanlage in den Fahrgastraum eines Kraftfahrzeugs,
und betrifft eine Luftführungseinrichtung
für ein
Fahrzeug nach dem Oberbegriff des Patentanspruchs 1.The
Invention is in the field of vehicle air conditioning
targeted air supply or air removal, in particular by means of a
Blowers and / or
an air conditioning system in the passenger compartment of a motor vehicle,
and relates to an air guide device
for a
Vehicle according to the preamble of

Dieser Ansatz optimiert zwar die Ausnutzung des für die Verlegung der Luftkanäle erforderlichen Bauraums. Allerdings ist dabei die Gestaltungsfreiheit und strömungstechnische Optimierung der Luftführung stark eingeschränkt, weil sich die Ausgestaltung der Luftkanäle nach den Geometrien der tragenden Karosserieteilen richten muss, die ihrerseits nach Festigkeits- und Steifigkeitskriterien ausgelegt sind.This Although the approach optimizes the utilization of the installation space required for the installation of the air ducts. However, there is the freedom of design and aerodynamic Optimization of the air duct highly limited, because the design of the air ducts according to the geometries of load bearing body parts, which in turn and stiffness criteria are designed.

Nachteilig bei diesen Aufbauten ist es, dass sie nicht dazu geeignet sind Luftführungseinrichtungen mit großer Gestaltungsfreiheit bereits beim Karosseriebau zu integrieren.adversely in these constructions it is that they are not suitable for air handling equipment with big ones Freedom of design already integrated in the body shop.
Vor diesem Hintergrund liegt nun der vorliegenden Erfindung die Aufgabe zugrunde, eine Luftführungseinrichtung anzugeben, deren Luftkanal flüssigkeitsdicht aufgebaut ist und die in der Gestaltung des Luftkanals einen großen Spielraum lässt und die zusätzlich zu einer erhöhten Steifigkeit der Fahrzeugkarosserie beiträgt.In front This is the background of the present invention basis, an air guide device specify whose air duct liquid-tight is constructed and in the design of the air duct a large margin lets and the additional to an increased Stiffness of the vehicle body contributes.
Erfindungsgemäß wird diese
Aufgabe durch eine Luftführungseinrichtung
mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention this
Task by an air guide device
solved with the features of
Demgemäß ist eine Luftführungseinrichtung vorgesehen, deren Hohlraum von einem Karosserieabschnitt und einem diesen überdeckenden, flächigen Versteifungselement begrenzt ist und die einen separaten ganz ummantelten Luftkanal aufweist, der über integrale Befestigungsvorrichtungen mit dem Karosserieabschnitt bzw. mit dem Versteifungselement verbunden ist.Accordingly, a Air guiding device provided, their cavity of a body section and a covering this, flat Stiffening element is limited and the a separate completely jacketed Air duct has over integral fasteners to the bodywork section or connected to the stiffening element.
Die der vorliegenden Erfindung zugrunde liegende Idee besteht unter anderem darin, insbesondere flächige und anderweitig kaum zur Karosseriesteifigkeit beitragende Karosserieabschnitte dadurch zu stärken und zu versteifen, dass zwischen diesen und dem Versteifungselement ein Bauraum oder Hohlraum geschaffen wird, in dem der Luftkanal verlegt ist. Dabei kann das Versteifungselement einerseits in seiner Geometrie sehr weitgehend nach den Erfordernissen der Luftkanalgestaltung, also mit großem Gestaltungsspielraum hinsichtlich der Form und des Querschnitts, aber andererseits vorteilhafterweise auch nach den zur Karosserieversteifung in diesen Bereichen günstigen Bauraum- oder Hohlraum-Querschnitten optimiert werden.The The idea underlying the present invention is under in it, in particular flat and otherwise hardly contributing to the body stiffness body sections to strengthen it and stiffen that between these and the stiffening element a space or cavity is created in which the air duct is relocated. In this case, the stiffening element on the one hand in his Geometry very largely according to the requirements of the air duct design, So with a big one Freedom of design with regard to shape and cross-section, but on the other hand advantageously also after the body stiffening favorable in these areas Installation space or cavity cross-sections are optimized.
Ferner weist der Luftkanal integrale Befestigungselemente auf, mit denen er an dem Karosserieabschnitt und/oder dem Versteifungselement befestigt ist. In diesem Zusammenhang ist es vorteilhaft, wenn die Befestigung flüssigkeitsdicht ausgebildet ist. Dann kann nämlich die erfindungsgemäße Luftführungseinrichtung bereits montiert werden, bevor die Karosserie bzw. das Fahrzeug weiteren Fertigungsschritten in flüssigen Medien – beispielsweise einer Tauchlackierung – unterzogen wird.Further has the air duct integral fasteners with which he attached to the body section and / or the stiffening element is. In this context, it is advantageous if the attachment liquid-tight is trained. Then you can the air guide device according to the invention already mounted before the body or the vehicle Further manufacturing steps in liquid media - for example, a Dipcoating - subjected becomes.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche sowie der Beschreibung unter Bezugnahme auf die Zeichnung.advantageous Embodiments and developments of the invention are the subject the dependent claims and the description with reference to the drawing.
Eine konstruktiv bevorzugte Ausgestaltung der Erfindung sieht vor, dass der Karosserieabschnitt ein Bodenblech ist. Dies verbessert ganz erheblich das Crashverhalten des Fahrzeugs und lässt besonders weiten Spielraum für die geometrische Gestaltung von Luftkanal und Versteifungselement.A structurally preferred embodiment of the invention provides that the body section is a floor panel. This improves completely considerably the crash behavior of the vehicle and leaves a particularly wide scope for the geometric design of air duct and stiffening element.
Gemäß einer dazu bevorzugten konstruktiven Weiterbildung der Erfindung ist das Versteifungselement ein profiliertes Blech, das beispielsweise eine im Querschnitt u-förmige Wölbung aufweist, unter der sich der Luftkanal erstreckt.According to one this preferred structural development of the invention is the Stiffening a profiled sheet, for example, a in cross-section U-shaped bulge has, under which the air passage extends.
Wie schon erwähnt, ermöglicht die Erfindung eine strömungstechnische Optimierung des Luftkanals. Durch den so verminderten Strömungswiderstand können zum Beispiel die zur Luftbewegung vorgesehenen Vorrichtungen, wie zum Beispiel ein Gebläse, entsprechend geringer und kostengünstiger dimensioniert werden. Ein dazu geeigneter und kostengünstiger Luftkanal kann einen rechteckigen Innenquerschnitt aufweisen. Der Luftkanal kann besonders kostengünstig aus temperatur- und formbeständigem Kunststoff gefertigt sein.As already mentioned, allows the invention is a fluidic Optimization of the air duct. Due to the reduced flow resistance can For example, provided for air movement devices, such as for example a blower, be dimensioned accordingly lower and cheaper. A suitable and cost effective Air duct may have a rectangular inner cross-section. Of the Air duct can be particularly inexpensive made of temperature and dimensionally stable Be made of plastic.
Das Versteifungselement kann mit der Karosserie lösbar, zum Beispiel durch Schrauben, oder aber auch als Montageteil ausgestaltet und/oder unlösbar, zum Beispiel mittels Klebung, Nieten oder Schweißung, verbunden sein.The Stiffening element can be detachably connected to the body, for example by means of screws, or as a mounting part designed and / or unsolvable, for Example, by gluing, riveting or welding, be connected.
Die Erfindung wird im Folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf die beiliegenden Figuren der Zeichnung näher erläutert. Es zeigen:The Invention will be described below with reference to exemplary embodiments with reference explained in more detail on the accompanying figures of the drawing. Show it:
In den Figuren der Zeichnung sind gleiche und funktionsgleiche Elementesofern nichts anderes angegeben ist – mit denselben Bezugszeichen versehen worden.In the figures of the drawing are the same and functionally identical elementesofern nothing else is stated - with the same reference numerals have been provided.
