Description

Die vorliegende Erfindung betrifft eine Entlüftungseinrichtung, insbesondere in einem Kraftfahrzeug, mit einem aus Kunststoff ausgebildeten Rahmen und mit zumindest einer beweglichen Rückschlagklappe aus Kunststoff gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem ein mit einer derartigen Entlüftungseinrichtung ausgestattetes Kraftfahrzeug.The present invention relates to a ventilation device, in particular in a motor vehicle, with a frame formed of plastic and at least one movable plastic check valve according to the preamble of claim 1. The invention also relates to a motor vehicle equipped with such a ventilation device.

Aus der DE 203 16 536 U1 ist eine gattungsgemäße Entlüftungseinrichtung für die Fahrzeugentlüftung bekannt, mit einem Rahmen, in welchem mindestens eine Ausströmöffnung gebildet ist. Diese wird von einem Ventilsitz umgeben und kann durch eine zugehörige Ventilklappe (Rückschlagklappe) geschlossen werden. Die Ventilklappe ist dabei aus einem elastisch federnden Material und derart angebracht, dass eine Rückstellkraft erzeugt wird, welche die Ventilklappe gegen den Ventilsitz beaufschlagt. Die Befestigung der Ventilklappe am Rahmen erfolgt mittels einer Befestigungsklammer.From the DE 203 16 536 U1 a generic venting device for vehicle ventilation is known, with a frame in which at least one outflow opening is formed. This is surrounded by a valve seat and can be closed by an associated valve flap (check valve). The valve flap is made of an elastically resilient material and mounted such that a restoring force is generated, which acts on the valve flap against the valve seat. The attachment of the valve flap on the frame by means of a mounting bracket.

Aus der DE 10 2006 056 868 A1 ist eine Rückluftsperre zur Entlüftung eines Innenraums eines Kraftfahrzeugs bekannt, mit einem Rahmen oder Gehäuse aus einem ersten Kunststoffmaterial und einer Ventilklappe aus biegsamem Material, das in einem Bereich mit dem Rahmen verbunden ist und in anderen Bereichen an einer Dichtfläche des Rahmens anliegt, sofern die Ventilklappe in Ruhestellung ist. Diese Ventilklappe hebt von der Dichtfläche ab, wenn sie einem Druckunterschied ausgesetzt ist, wobei die Ventilklappe als dünne Platte aus einem geschlossenporigen, geschäumten Material geformt ist. Hierdurch soll die Ventilklappe in geschlossenem Zustand möglichst dicht an der Dichtfläche anliegen und zugleich nach Möglichkeit keine oder nur geringfügige Geräusche erzeugen.From the DE 10 2006 056 868 A1 a return air lock for venting an interior of a motor vehicle is known, with a frame or housing made of a first plastic material and a valve flap made of flexible material, which is connected in one area with the frame and in other areas on a sealing surface of the frame, provided the valve flap is at rest. This valve flap lifts off the sealing surface when subjected to a pressure differential, the valve flap being formed as a thin plate of closed-cell, foamed material. As a result, the valve flap should lie as close as possible to the sealing surface in the closed state and at the same time produce no or only slight noise as far as possible.

Schließlich ist aus der DE 20 2007 006 724 U1 eine Entlüftungsklappe zur Entlüftung eines Innenraumes eines Kraftfahrzeugs bekannt, mit einem aus einem ersten Material bestehenden Rahmen und wenigstens einer Rückschlagklappe, wobei an den Rahmen ein umlaufendes Federelement angeformt ist, das zumindest in Teilbereichen eine Dichtung aus einem zweiten Material aufweist. Hierdurch soll eine Entlüftungsklappe geschaffen werden, die eine einfache und kostengünstige Herstellung sowie eine zuverlässige Abdichtung ermöglicht.Finally, out of the DE 20 2007 006 724 U1 a ventilation flap for venting an interior of a motor vehicle known, comprising a frame consisting of a first material and at least one non-return valve, wherein on the frame a circumferential spring element is formed, which has a seal made of a second material at least in some areas. As a result, a ventilation flap is to be created, which allows a simple and cost-effective production and a reliable seal.

Bei den aus dem Stand der Technik bekannten Entlüftungseinrichtungen werden die Rückschlagklappen üblicherweise über Schraub-, Klammer- oder Clipsverbindungen mit einem diese kragenden Rahmen verbunden, was vergleichsweise aufwändig und teuer ist.In the venting devices known from the prior art, the check valves are usually connected via screw, staple or clip connections with a cantilevered frame, which is relatively complicated and expensive.

Die vorliegende Erfindung beschäftigt sich mit Problem, für eine Entlüftungseinrichtung der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere für eine einfache und kostengünstige Herstellung auszeichnen.The present invention is concerned with the problem of providing for a venting device of the generic type an improved or at least one alternative embodiment, which are particularly suitable for a simple and cost-effective production.

Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine Rückschlagklappe einer Entlüftungseinrichtung an einen Rahmen dieser Entlüftungseinrichtung mittels einer Schweißverbindung anzubinden und nicht wie bisher üblich, mittels beispielsweise aufwändig zu montierenden und teuren Klammern. Eine derartige Schweißverbindung lässt sich einerseits fertigungstechnisch einfach herstellen und gewährleistet andererseits eine zuverlässige Verbindung der Rückschlagklappe mit dem Rahmen, wodurch insbesondere auch eine hohe Dichtfunktion gewährleistet werden kann. Von besonderem Vorteil ist jedoch, dass im Unterschied zum Stand der Technik zusätzliche Befestigungselemente, wie beispielsweise Befestigungsklammern, entfallen, wodurch sich einerseits die Teilevielfalt reduziert und andererseits der Montageaufwand verringert. Insgesamt lassen sich dadurch die Kosten zur Herstellung einer derartigen Entlüftungseinrichtung deutlich reduzieren.The present invention is based on the general idea of connecting a non-return valve of a venting device to a frame of this venting device by means of a welded connection and not, as usual, by means of, for example, expensive to install and expensive clamps. On the one hand, such a welded connection can be easily manufactured and, on the other hand, ensures a reliable connection of the non-return flap to the frame, as a result of which, in particular, a high sealing function can be ensured. Of particular advantage, however, that in contrast to the prior art additional fasteners, such as mounting brackets, omitted, which on the one hand reduces the variety of parts and on the other hand reduces the assembly cost. Overall, this can significantly reduce the costs for producing such a venting device.

Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist die Schweißverbindung mittels Ultraschallschweißen hergestellt. Aus dem Ultraschallschweißen können Kunststoffe, insbesondere thermoplastische Kunststoffe miteinander verschweißt werden, wobei die nötige Energie durch eine hochfrequente mechanische Schwingung erreicht wird, welche zwischen den zu verschweißenden Bauteilen durch Molekular- und Grenzflächenreibung entsteht. Generell gehört somit das Ultraschallschweißen eigentlich zur Gruppen der Reibschweißungen. Erzeugt wird die erforderliche Ultraschallfrequenz mit Hilfe eines Hochfrequenzgenerators, der die Netzspannung in eine Hochfrequenz umwandelt. Durch ein geschirmtes Kabel wiederum wird die Hochfrequenzleistung zu einem Ultraschallwandler übertragen, der beispielsweise mit dem piezoelektrischen Effekt oder einem magnetostriktiven Effekt arbeitet. Die erzeugten Schwingungen werden dabei unter Druck auf das zu schweißende Werkstück übertragen, wobei der zu schweißende Werkstoff aufgrund der Temperaturerhöhung erweicht und schmilzt. Generell zeichnet sich das Ultraschallschweißen durch sehr geringe Schweißzeiten und eine hohe Wirtschaftlichkeit aus. In an advantageous development of the solution according to the invention, the welded connection is produced by means of ultrasonic welding. From the ultrasonic welding plastics, especially thermoplastics can be welded together, the necessary energy is achieved by a high-frequency mechanical vibration, which arises between the components to be welded by molecular and interface friction. In general, therefore, ultrasonic welding actually belongs to the groups of friction welding. The required ultrasound frequency is generated by means of a high frequency generator, which converts the mains voltage into a high frequency. By a shielded cable turn the high-frequency power is transmitted to an ultrasonic transducer, which works for example with the piezoelectric effect or a magnetostrictive effect. The vibrations generated are transferred under pressure to the workpiece to be welded, wherein the material to be welded softens and melts due to the increase in temperature. In general, ultrasonic welding is characterized by very short welding times and high cost-effectiveness.

Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung sind am Rahmen zumindest zwei Zapfen angeordnet, die durch entsprechende Ausnehmungen an der Rückschlagklappe hindurchgreifen, wobei die Zapfen nach dem Herstellen der Schweißverbindung einen umgeformten Kopf aufweisen, dessen Durchmesser größer ist als der Durchmesser der zugehörigen Ausnehmung. Hier wird die erfindungsgemäße Schweißverbindung somit zusätzlich durch eine mechanische Verbindung, nämlich die Zapfenverbindung, unterstützt. Zum Fixieren der Rückschlagklappe am Rahmen der Entlüftungseinrichtung wird die Rückschlagklappe zunächst mit ihren Ausnehmungen über die rahmenseitig angeordneten Zapfen geführt und anschließend ein entsprechender Schweißstempel auf die Zapfen gedrückt, wodurch sich bei diesen ein nietähnlicher Kopf bildet. Die Anzahl der Zapfen je Rückschlagklappe kann dabei individuell gewählt werden. Generell kann neben dem reinen Umformen des Kopfes des Zapfens auch ein Verschweißen desselben mit einem Rand der Ausnehmung der Rückschlagklappe erfolgen, wodurch die Verbindung zusätzlich verstärkt wird.In an advantageous development of the solution according to the invention at least two pins are arranged on the frame, which pass through corresponding recesses on the non-return valve, wherein the pins after the production of the welded joint have a deformed head whose diameter is greater than the diameter of the associated recess. Here, the welded joint according to the invention is thus additionally supported by a mechanical connection, namely the pin connection. To fix the non-return valve on the frame of the venting device, the non-return valve is first performed with their recesses on the frame side arranged pins and then pressed a corresponding welding die on the pins, which forms a rivet-like head in these. The number of pins per non-return valve can be selected individually.
