Abstract
Description
Die Erfindung betrifft eine Motorhaube für ein Kraftfahrzeug mit einer Außenhaut, an deren Unterseite wenigstens ein Frisch luftführungskanal sowie eine dem Frischluftführungskanal zuge ordnete Filteranordnung angeordnet sind.The invention relates to a hood for a motor vehicle with an outer skin, on the underside of which at least one fresh air duct and one supplied to the fresh air duct arranged filter arrangement are arranged.
Eine solche Motorhaube ist für einen Personenkraftwagen aus der DE 39 23 307 C2 bekannt. Um eine Hutze für einen Frischluftein laß im Bereich der Oberseite einer Motorhaube zu vermeiden und die durch diese Hutze auftretenden Gefahren beim Aufprall eines Fußgängers zu reduzieren, ist ein Frischluftführungskanal ein schließlich einer entsprechenden Filteranordnung an einer Un terseite der Außenhaut der Motorhaube angebracht.Such a hood is for a passenger car from the DE 39 23 307 C2 known. Around a scoop for fresh air to avoid in the area of the top of a hood and the dangers arising from this scoop in the event of an impact To reduce pedestrian traffic is a fresh air duct finally a corresponding filter arrangement at a Un attached to the outer skin of the bonnet.
Aufgabe der Erfindung ist es, eine Motorhaube der eingangs ge nannten Art zu schaffen, die im Hinblick auf die Verletzungsge fahr aufprallender Fußgänger weiter verbessert ist.The object of the invention is to provide a hood of the ge named kind to create, with regard to the injury law driving impacting pedestrians is further improved.
Diese Aufgabe wird dadurch gelöst, dass an der Unterseite der Außenhaut wenigstens eine sich flächig über die Unterseite er streckende Energieaufnahmestruktur vorgesehen ist, in die der Frischluftführungskanal und die Filteranordnung räumlich integ riert sind. Durch die Energieaufnahmestruktur wird der Aufprall eines Fußgängers gedämpft. Die Energieaufnahmestruktur gewähr leistet zudem eine Reduzierung der Schallabstrahlung nach oben, so dass auf eine Geräuschdämmmatte im Bereich der Unterseite der Motorhaube verzichtet werden kann. Die Integration der Luftzufuhr in die Motorhaube ermöglicht es zudem, entsprechende Aggregateteile des Motorraumes in größerem Abstand zur Motor haube anzuordnen, als dies beim Stand der Technik der Fall ist. Vorzugsweise soll der Abstand der oberen Kontur entsprechender Aggregateteile des Motorraumes zur Außenhaut der Motorhaube wenigstens 40 mm bis 80 mm betragen. Dadurch wird für die Motorhau be ein ausreichender Deformationsweg beim Aufprall eines Fuß gängers zur Verfügung gestellt, der die gute Wirksamkeit der Energieaufnahmestruktur an der Unterseite der Außenhaut der Mo torhaube unterstützt. Die Energieaufnahmestruktur kann innen seitig, d. h. zum Motorraum hin noch durch eine Innenhaut in Form eines Abdeckbleches oder ähnlichem überzogen sein, so dass die Energieaufnahmestruktur unsichtbar an der Motorhaube posi tioniert ist. Die Energieaufnahmestruktur weist vorzugsweise mechanisch deformierbare Elemente auf, indem die Energieaufnah mestruktur waben- oder rippenartig gestaltet ist. In gleicher Weise sind jedoch auch andere Arten von Energieaufnahmestruktu ren einsetzbar, die eine wirksame Dämpfung des Aufpralls eines Fußgängers bewirken. Da nach außen lediglich die glattflächige Außenhaut sichtbar ist, kann sowohl die Energieaufnahmestruktur als auch die Frischluftzufuhr formschön in die Motorhaube in tegriert sein. Durch die Energieaufnahmestruktur kann die Mo torhaube in Sandwichbauweise gestaltet sein. Die sich flächig über die Motorhaube erstreckende Energieaufnahmestruktur ermög licht es, Mindestabstände der oberen Konturen von Aggregatetei len des Motorraumes zur Außenhaut zu reduzieren, da durch das Energieabsorptionsvermögen der Energieaufnahmestruktur bereits bei reduziertem Deformationsweg die gleiche Energieabsorption erzielt wird wie bei einer Motorhaube ohne eine solche Energie aufnahmestruktur. Dadurch ist es möglich, den für den Motorraum und die entsprechenden Aggregate notwendigen Bauraum zu redu zieren, wodurch für das optische Design etwas größere Gestal tungsmöglichkeiten zur Verfügung stehen. Je nach Gestaltung der Energieaufnahmestruktur ist es somit möglich, den Abstand der oberen Kontur der Aggregateteile des Motorraumes zur Außenhaut gegebenenfalls sogar unter dem oben angegebenen Bereich von 40 mm bis 80 mm anzusiedeln.This problem is solved in that at the bottom of the Outer skin at least one flat over the bottom stretching energy absorption structure is provided, in which the Fresh air duct and the filter arrangement spatially integrated are. The impact is caused by the energy absorption structure of a pedestrian muffled. Grant the energy absorption structure also achieves an upward reduction in sound radiation, so that on a noise insulation mat in the area of the bottom the bonnet can be dispensed with. The integration of the Air supply in the hood also allows appropriate Parts of the engine compartment at a greater distance from the engine to arrange hood than is the case with the prior art. The distance of the upper contour should preferably be more appropriate Parts of the engine compartment to the outer skin of the hood at least 40 mm to 80 mm. This is for the engine house be a sufficient deformation path when a foot hits provided that the good effectiveness of Energy absorption structure on the underside of the outer skin of the Mo supported hood. The energy absorption structure can be inside sided, d. H. to the engine compartment through an inner skin Be covered in the form of a cover plate or the like, so that the energy absorption structure is invisible on the bonnet posi is dated. The energy absorption structure preferably has mechanically deformable elements by absorbing the energy The structure is honeycomb or rib-like. In the same However, other types of energy absorption structure are also wise Ren can be used, which effectively dampens the impact of a Effect pedestrian. Since only the smooth surface on the outside Outer skin is visible, both the energy absorption structure as well as the fresh air supply in the bonnet be tegrated. Due to the energy absorption structure, the Mo Door hood can be designed in sandwich construction. The flat Enabling energy absorption structure extending over the hood light it, minimum distances of the upper contours of aggregate len to reduce the engine compartment to the outer skin, because by the Energy absorption capacity of the energy absorption structure already the same energy absorption with a reduced deformation path is achieved like a bonnet without such energy receptive structure. This makes it possible for the engine compartment and the corresponding units to reduce the installation space required adorn, which makes the design slightly larger options are available. Depending on the design of the Energy absorption structure, it is thus possible to distance the upper contour of the aggregate parts of the engine compartment to the outer skin possibly even under the range of To settle 40 mm to 80 mm.
In Ausgestaltung der Erfindung ist für die Positionierung der Filteranordnung ein Filterraum an der Unterseite der Außenhaut vorgesehen, der durch eine nach unten öffnende Abdeckklappe verschließbar ist. Dadurch ist bei geöffneter Motorhaube ein einfacher Austausch der Filteranordnung möglich.In one embodiment of the invention is for the positioning of the Filter arrangement a filter space on the underside of the outer skin provided by a cover flap opening downwards is lockable. This means that when the bonnet is open easy replacement of the filter arrangement possible.
In weiterer Ausgestaltung der Erfindung ist der Frischluftfüh rungskanal derart an der Unterseite der Außenhaut positioniert, dass er sich koaxial zu einer Fahrzeugmittellängsachse er streckt. Vorzugsweise ist auch der Filterraum symmetrisch zur Fahrzeugmittellängsachse angeordnet. Dadurch wird eine beson ders platzsparende Unterbringung der Frischluftzufuhr ermög licht, da im Bereich der Motorhaubenmitte zum einen eine einfa che Frischluftansaugung und zum anderen eine gute Weiterleitung zum Motor ermöglicht sind.In a further embodiment of the invention, the fresh air guide positioned on the underside of the outer skin that it is coaxial with a vehicle central longitudinal axis stretches. The filter space is preferably also symmetrical to Vehicle central longitudinal axis arranged. This is a special which enables space-saving accommodation of the fresh air supply light, because in the area of the bonnet center a simple che fresh air intake and on the other hand good forwarding to the engine are possible.
Vorzugsweise entspricht die Höhe des Filterraumes und die Höhe des Frischluftführungskanals maximal der Dicke der Energieauf nahmestruktur, so dass die Frischluftzufuhr vollständig in der Energieaufnahmestruktur eingebettet ist.The height of the filter space and the height preferably correspond of the fresh air duct maximum of the thickness of the energy structure, so that the fresh air supply is completely in the Energy absorption structure is embedded.
Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ansprüchen sowie aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung, das anhand der Zeichnungen dargestellt ist.Further advantages and features of the invention result from the claims and from the following description of a preferred embodiment of the invention, which is based on the Drawings is shown.
Fig. 1 zeigt schematisch in perspektivischer Darstellung eine Ausführungsform einer erfindungsgemäßen Motorhaube in ihrem montierten Zustand an einem Personenkraftwagen, Fig. 1 shows schematically in perspective an embodiment of a hood according to the invention in its mounted state on a passenger car,
Fig. 2 schematisch in einer Schnittdarstellung einen Vorbaube reich des Personenkraftwagens nach Fig. 1 mit geschlos sener Motorhaube und Fig. 2 shows schematically in a sectional view a stem of the rich passenger car of FIG. 1 with closed hood and
Fig. 3 die Schnittdarstellung nach Fig. 2, jedoch mit geöffne ter Motorhaube. Fig. 3 shows the sectional view of FIG. 2, but with the hood open.
Ein Personenkraftwagen 2 nach den Fig. 1 bis 3 weist in einem Vorbaubereich einen Motorraum auf, in dem ein nicht näher be zeichnetes Antriebsaggregat sowie weitere, grundsätzlich bekannte Funktionsaggregate untergebracht sind. Der Motorraum ist durch eine Motorhaube 1 verschließbar, die sich von einem frontseitigen Kühlergrill 3 bis zu einer Windschutzscheibe hin und seitlich bis zu anschließenden Kotflügeln erstreckt. Die Motorhaube 1 ist mit einer glattflächigen Außenhaut 4 versehen, die in geeigneter Weise als Blech- oder Kunststoffschale ge staltet ist. An der Unterseite der Außenhaut 4 ist die Motor haube 1 flächig mit einer Energieaufnahmestruktur 5 versehen, die beim dargestellten Ausführungsbeispiel durch eine energie absorbierend deformierbare Rippenstruktur gebildet ist, wie an hand der Fig. 1 durch die entsprechend aufgebrochene Darstel lung des anschließenden linken Kotflügels erkennbar ist.A passenger car 2 according to FIGS . 1 to 3 has an engine compartment in a porch area in which a drive unit, not shown, and further, basically known functional units are accommodated. The engine compartment can be closed by a bonnet 1 , which extends from a front grille 3 to a windshield and laterally to the adjoining fenders. The hood 1 is provided with a smooth outer skin 4 , which is designed in a suitable manner as a sheet metal or plastic shell. On the underside of the outer skin 4 , the engine hood 1 is provided with a flat surface with an energy absorption structure 5 , which is formed in the illustrated embodiment by an energy-absorbing deformable rib structure, as can be seen in FIG. 1 by the correspondingly broken presen- tation of the subsequent left wing ,
Wie zudem anhand der Fig. 2 erkennbar ist, befinden sich alle oberen Randkonturen des Antriebsaggregates sowie der anderen, im Motorraum befindlichen Funktionsaggregate in einem bestimm ten Abstand zu einer Unterseite der Motorhaube 1, der vorzugs weise zwischen 40 mm und 80 mm beträgt. Hierdurch wird für eine Deformation der Motorhaube 1 nach unten, insbesondere aufgrund eines Fußgängeraufpralls, ein gewisser Freiraum zur Verfügung gestellt, der durch die Deformation der Motorhaube 1 sowie die Energieaufnahmestruktur 5 eine gewisse Dämpfung des Fußgänger aufpralls bewirkt, so dass Verletzungsgefahren für auf den Per sonenkraftwagen 2 aufprallende Fußgänger reduziert werden.As can also be seen from FIG. 2, all the upper edge contours of the drive unit and the other functional units located in the engine compartment are at a certain distance from an underside of the hood 1 , which is preferably between 40 mm and 80 mm. As a result, a certain amount of free space is made available for a deformation of the bonnet 1 , in particular due to a pedestrian impact, which causes a certain damping of the pedestrian by the deformation of the bonnet 1 and the energy absorption structure 5 , so that there is a risk of injury to the passenger car 2 impacting pedestrians can be reduced.
Im mittleren Bereich der Motorhaube 1, und zwar symmetrisch zu einer Mittellängsachse bzw. einer vertikalen Mittellängsebene des Personenkraftwagens, ist zudem an der Unterseite der Außen haut 4 der Motorhaube 1 eine Frischluftzufuhranordnung in Form eines Frischluftführungskanals 8, 9, 10 sowie einer Filteran ordnung 12 angebracht. Um die Unterbringung des Frischluftfüh rungskanales 8 bis 10, der für die Aufnahme der Filteranordnung 12 einen als Gehäuse gestalteten Filterraum 9 bildet, zu ermög lichen, ist die Energieaufnahmestruktur 5 über die Abmessungen dieses Frischluftführungskanals 8 bis 10 ausgespart, so dass der Frischluftführungskanal 8, 10 einschließlich des als Gehäu se gestaltete Filterraumes 9 flächenbündig in die Energieaufnahmestruktur 5 eingebettet werden kann. Die Höhe des Frisch luftführungskanals 8, 10 und des Filterraumes 9 entspricht der Dicke der Energieaufnahmestruktur 5. Der Frischluftführungska nal 8, 10 wie auch das den Filterraum 9 bildende Gehäuse sind vorzugsweise aus Kunststoff gestaltet und mit der Kehrseite der Außenhaut verklebt. Die Filteranordnung 12 ist beim dargestell ten Ausführungsbeispiel als Staubfilter ausgeführt. In gleicher Weise sind jedoch auch andere Arten von geeigneten Filtern ein setzbar, auf die der Fachmann je nach Anforderungen an die Luftfilterung zurückgreifen wird.In the central area of the hood 1 , symmetrically to a central longitudinal axis or a vertical central longitudinal plane of the passenger car, a fresh air supply arrangement in the form of a fresh air duct 8 , 9 , 10 and a filter arrangement 12 is also attached to the underside of the outer skin 4 of the hood 1 , In order to accommodate the Frischluftfüh approximately channel 8 to 10 which forms a designed as a housing filter chamber 9 for receiving the filter assembly 12 to made handy, the energy absorbing structure is recessed 5 via the dimensions of this fresh air duct 8 to 10, so that the fresh air duct 8, 10 including the filter chamber 9 designed as a housing can be embedded flush in the energy absorption structure 5 . The height of the fresh air duct 8 , 10 and the filter chamber 9 corresponds to the thickness of the energy absorption structure 5 . The fresh air guide channel 8 , 10 as well as the housing forming the filter chamber 9 are preferably made of plastic and glued to the downside of the outer skin. The filter arrangement 12 is designed in the embodiment shown as a dust filter. In the same way, however, other types of suitable filters can be used, which the person skilled in the art will use depending on the requirements for air filtering.
Wie anhand der längs der vertikalen Mittellängsebene ausgeführ ten Schnittdarstellung gemäß den Fig. 2 und 3 erkennbar ist, weist der vordere Kanalabschnitt 8 des Frischluftführungskanals 8 bis 10 eine Eintrittsöffnung 14 auf, die an der Unterseite des Kanalabschnittes 8 vorgesehen ist und mit einer umlaufenden Dichtung versehen ist. Korrespondierend hierzu ist am Fahrzeug vorbau, vorliegend im Bereich des Kühlergrills 3, ein Ein trittskrümmer 7 vorgesehen, der einen in Fahrtrichtung nach vorne ragenden Lufteintritt 5 aufweist. Das ausgangsseitige En de des Krümmers 7 ist auf die Eintrittsöffnung 14 des Kanalab schnittes 8 derart abgestimmt, dass bei geschlossener Motorhau be (Fig. 2) eine durchgängige Kanalverbindung zwischen Krümmer 7 und Kanalabschnitt 8 geschaffen wird, wobei die Dichtung der Eintrittsöffnung 14 dichtend auf dem ausgangsseitigen Randbe reich des Krümmers 7 aufliegt.As can be seen from the along the vertical center longitudinal plane out guide th sectional view of FIGS. 2 and 3, the front channel section 8 of the fresh air duct 8 to 10 an inlet opening 14 which is provided on the underside of the channel portion 8 and provided with a circumferential seal is. Corresponding to this, the grille 3, a is a stem on the vehicle, in this case in the range trittskrümmer 7 is provided, which has a projecting towards the front air inlet. 5 The output side En de of the manifold 7 is matched to the inlet opening 14 of the Kanalab section 8 such that when the engine is closed ( FIG. 2) a continuous channel connection between the manifold 7 and the channel section 8 is created, the seal of the inlet opening 14 sealingly on the output-side Randbe rich of the manifold 7 rests.
Der hintere, ausgangsseitige Kanalabschnitt 10 ist mit einem nach unten abragenden Anschlussstutzen 15 versehen, auf den ein flexibler Schlauch 11 aufsteckbar und fixierbar ist. Der fle xible Schlauch 11 schafft die Verbindung der Luftzufuhr zum An triebsaggregat. Die Flexibilität des Schlauches 11 ermöglicht ein Öffnen und Schließen der Motorhaube 1 (Fig. 3), ohne dass die Verbindung zwischen Schlauch 11 und Anschlussstutzen 15 un terbrochen wird. The rear, outlet-side channel section 10 is provided with a downwardly projecting connecting piece 15 , onto which a flexible hose 11 can be plugged and fixed. The flexible hose 11 creates the connection of the air supply to the drive unit. The flexibility of the hose 11 enables the hood 1 to be opened and closed ( FIG. 3) without the connection between the hose 11 and the connecting piece 15 being interrupted.
Das den Filterraum 9 bildende Gehäuse ist an seiner Unterseite durch eine Abdeckklappe 13 verschlossen, die um eine Scharnier achse 16 gemäß der Darstellung nach den Fig. 2 und 3 schwenkbe weglich gelagert ist. Nach dem Öffnen der Abdeckklappe 13 ist somit die Filteranordnung 12 frei zugänglich und kann gereinigt oder ausgetauscht werden. Selbstverständlich ist der Abdeck klappe 13 eine Verschlussanordnung zugeordnet, um den sicheren Halt der Abdeckklappe 13 in der geschlossenen Position zu ge währleisten.The housing forming the filter chamber 9 is closed on its underside by a cover flap 13 which is pivotally mounted about a hinge axis 16 as shown in FIGS . 2 and 3. After opening the cover flap 13 , the filter arrangement 12 is thus freely accessible and can be cleaned or replaced. Of course, the cover flap 13 is assigned a locking arrangement to ensure the secure hold of the cover flap 13 in the closed position.
Im Fahrbetrieb des Personenkraftwagens 2 kann somit Fahrtwind als Frischluft F (Fig. 1) über den Frischlufteintritt 6, den Krümmer 7 und den Frischluftführungskanal 8, 10 unter Reinigung innerhalb der Filteranordnung 12 dem Schlauch 11 und damit dem Antriebsaggregat zugeführt werden, um das entsprechende Kraft stoff/Luftgemisch für die Verbrennung zu schaffen.When the passenger car 2 is in operation, the air stream can be supplied as fresh air F ( FIG. 1) via the fresh air inlet 6 , the manifold 7 and the fresh air duct 8 , 10 while cleaning within the filter arrangement 12, the hose 11 and thus the drive unit by the corresponding force create substance / air mixture for combustion.
