Abstract
Description
Die vorliegende Erfindung betrifft ein Kraftfahrzeug mit einem Wasserkasten, der einen Spalt zwischen einer Fronthaube und einer Frontscheibe des Fahrzeugs überbrückt. Der Wasserkasten dient unter anderem dazu, von der Frontscheibe ablaufendes Niederschlagswasser zu sammeln und abzuführen, so dass es sich nicht unkontrolliert im Innern der Kraftfahrzeugkarosserie verteilen kann.The present invention relates to a motor vehicle with a water tank, which bridges a gap between a front hood and a windshield of the vehicle. Among other things, the water tank is used to collect and drain rainwater running off the windshield so that it can not be distributed uncontrollably in the interior of the motor vehicle body.
Aus
Insbesondere bei kompakten Fahrzeugen mit kurzer Fronthaube ergibt sich das Problem, dass, wenn bei einem Unfall ein Fußgänger angestoßen wird und auf die Haube stürzt, der Kopf nicht mehr auf die Haube sondern auf die Frontscheibe trifft. Die Frontscheibe muss einerseits nachgiebig genug sein, um auch die demnächst verschärften gesetzlichen Grenzwerte des Head-Impact-Criterium (HIC) einhalten zu können, andererseits muss ihre Abstützung aber bei möglichst geringem Gewicht steif genug sein, um eine Verformung, die zu einer Schädigung der Frontscheibe führen kann, außerhalb einer Unfallsituation sicher auszuschließen.In particular, in compact vehicles with a short front hood, the problem arises that when a pedestrian is triggered in an accident and crashes on the hood, the head no longer hits the hood but on the windshield. On the one hand, the windshield must be yielding enough to be able to comply with the soon-to-be-tightened head-impact-criterion (HIC), but on the other hand its support must be stiff enough, with as little weight as possible, to prevent deformation that could damage the head Windscreen can lead to safely exclude outside an accident situation.
Die Aufgabe wird gelöst, indem bei einem Kraftfahrzeug mit einem einen Spalt zwischen einer Fronthaube und einer Frontscheibe überbrückenden Wasserkasten eine Rückwand des Wasserkastens eine Auflage der Frontscheibe trägt und mit einer durch eine Deformation der Auflage zerstörbaren Schwachstelle versehen ist. Solange die Rückwand unversehrt ist, kann die Auflage die Frontscheibe sicher unterstützen und vor einer Verformung, die zur Beschädigung führen könnte, schützen. Wenn jedoch bei einem Unfall die Frontscheibe einem Schlag ausgesetzt ist, der hart genug ist, um die Schwachstelle zu zerstören, dann ist auch die Unterstützung der Auflage geschwächt und die Frontscheibe ist leicht nachgiebig.The object is achieved by carrying in a motor vehicle with a gap between a front hood and a windscreen bridging water tank a rear wall of the water box bearing the windscreen and is provided with a destructible by a deformation of the support vulnerability. As long as the back wall is intact, the support can safely support the windscreen and protect it from deformation that could damage it. However, in the event of an accident, if the windshield is subjected to a stroke that is hard enough to destroy the flaw, the support of the overlay is weakened and the windshield is slightly yielding.
Vorzugsweise weist die Schwachstelle eine geringere Wandstärke auf als benachbarte Bereiche der Rückwand.Preferably, the weak point has a smaller wall thickness than adjacent areas of the rear wall.
Um Gewicht einzusparen, kann wenigstens die Rückwand des Wasserkastens aus Kunststoff geformt sein. Außerdem vereinfacht die Verwendung von Kunststoff die Realisierung der Schwachstelle.To save weight, at least the rear wall of the water box can be formed of plastic. In addition, the use of plastic simplifies the realization of the vulnerability.
Vorzugsweise erstreckt sich die Schwachstelle über die gesamte Breite der Rückwand, um eine im Wesentlichen gleichbleibende Nachgiebigkeit der Frontscheibe entlang ihres gesamten von der Auflage unterstützten unteren Randes zu erzielen.Preferably, the weak point extends across the entire width of the backplane to achieve substantially consistent compliance of the windshield along its entire bottom edge supported by the overlay.
Vorzugsweise hängt die Auflage mit der Rückwand einteilig zusammen.Preferably, the support hangs integrally with the rear wall.
Die einteilige Verbindung kann insbesondere durch eine Biegezone zwischen einem scheibennahen Bereich der Rückwand und der Auflage gebildet sein. Um die Biegezone zu versteifen und eine sichere Zerstörung der Schwachstelle bei einem Aufschlag zu gewährleisten, kann die Biegezone durch eine sich über die Biegezone hinweg, zwischen dem scheibennahen Bereich und der Auflage erstreckende Rippe versteift sein.The one-piece connection can be formed, in particular, by a bending zone between a pane-near region of the rear wall and the support. In order to stiffen the bending zone and to ensure a safe destruction of the weak point at impact, the bending zone may be stiffened by a rib extending across the bending zone, between the disc-proximate region and the support.
Um der Rückwand eine zum wirksamen Abstützen der Frontscheibe ausreichende Steifigkeit bei geringem Materialeinsatz zu verleihen, kann in einem zu der Schwachstelle benachbarten Bereich der Rückwand, insbesondere einem Bereich auf der von der Scheibe abgewandten Seite der Schwachstelle, wenigstens eine auf die Schwachstelle zulaufende Rippe geformt sein.In order to give the rear wall a sufficient rigidity for effective support of the windshield with low material usage, in a region adjacent to the weak point area of the rear wall, in particular a region on the side facing away from the disk side of the vulnerability, at least one tapering to the weak point rib can be formed ,
Indem die Rückwand des Wasserkastens eine sich zwischen Motorraum und Fahrgastzelle des Kraftfahrzeugs erstreckende Stirnwand mit der Frontscheibe verbindet, kann sie die Frontscheibe mittelbar an der Stirnwand abstützen.By connecting the rear wall of the water tank a between the engine compartment and passenger compartment of the motor vehicle extending end wall with the windscreen, it can indirectly support the windscreen on the end wall.
Die Rückwand des Wasserkastens kann zweiteilig, aus einem oberen und einem unteren Segment zusammengefügt sein. Wenn diese zwei Segmente entlang zweier sich berührender, zur Seite der Fahrgastzelle vorspringender Flansche verbunden sind, können diese Flansche gleichzeitig zur Unterstützung von Einbauten der Fahrgastzelle dienen.The rear wall of the water box can be composed of two parts, an upper and a lower segment. When these two segments are connected along two contacting flanges projecting to the side of the passenger compartment, these flanges can simultaneously serve to support the cabin of the passenger compartment.
Eine vordere Wand, die den Wasserkasten vervollständigt, und die Rückwand können über aneinander und an der Stirnwand anliegende Flansche verbunden sein.A front wall, which completes the water box, and the rear wall may be connected by flanges abutting one another and on the end wall.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Aus dieser Beschreibung und den Figuren gehen auch Merkmale der Ausführungsbeispiele hervor, die nicht in den Ansprüchen erwähnt sind. Solche Merkmale können auch in anderen als den hier spezifisch offenbarten Kombinationen auftreten. Die Tatsache, dass mehrere solche Merkmale in einem gleichen Satz oder in einer anderen Art von Textzusammenhang miteinander erwähnt sind, rechtfertigt daher nicht den Schluss, dass sie nur in der spezifisch offenbarten Kombination auftreten können; stattdessen ist grundsätzlich davon auszugehen, dass von mehreren solchen Merkmalen auch einzelne weggelassen oder abgewandelt werden können, sofern dies die Funktionsfähigkeit der Erfindung nicht in Frage stellt. Es zeigen:Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. From this description and the figures also show features of the embodiments, which are not mentioned in the claims. Such features may also occur in combinations other than those specifically disclosed herein. The fact that several such features in a same sentence or in one therefore not conclude that they can occur only in the combination specifically disclosed; instead, it is generally to be assumed that it is also possible to omit or modify individual ones of several such features, provided this does not call into question the functionality of the invention.
