ScheinwerferHeadlights

BeschreibungDescription

Die Erfindung betrifft einen Scheinwerfer umfassend ein Scheinwerfergehäuse sowie eine Abdeckung zum Abschluss des Scheinwerfergehäuses in Lichtabstrahlrichtung einer im Scheinwerfer integrierten Lichtquelle, wobei das Scheinwerfergehäuse und die Abdeckscheibe dicht miteinander verbunden sind.
25The invention relates to a headlight comprising a headlight housing and a cover for closing the headlight housing in the light emission direction of a light source integrated in the headlight, wherein the headlight housing and the cover plate are tightly connected to one another.
25

Bei den heute üblichen Kfz-Scheinwerfern wird zur Verbindung des Scheinwerfergehäuses, bei dem es sich zumeist um ein aus dunkel eingefärbtem thermoplastischem Kunststoff bestehendes Gehäuse oder Zwischenrahmen handelt, mit der aus zumeist transparentem thermoplastischem Kunststoff bestehenden Abdeckscheibe, vorgesehen, die beiden Bestandteile über Ein- oder Zwei-Komponenten-Silikonklebern miteinander zu verbinden.In today's common car headlights, the headlight housing, which is usually a housing or intermediate frame made of dark-colored thermoplastic, and the cover plate, which is usually made of transparent thermoplastic, are connected to one another using one- or two-component silicone adhesives.

Darüber hinaus sind weitere Dichtmittel und zusätzliche Halteklammern üblich. Auch Dichtungen mit Haltefedern werden eingesetzt sowie die Verfahren des Vibrationsschweißens, Heizelementschweißens und Ultraschallschweißens.In addition, other sealing agents and additional retaining clips are common. Seals with retaining springs are also used, as well as vibration welding, hot plate welding and ultrasonic welding processes.

Die Verbindung mittels Dichtmittel besitzt den Nachteil eines erhöhten Platzbedarfs, wodurch der in der Karosserie ohnehin spärliche Bauraum nicht optimal genutzt werden kann. Gerade bei der Auslegung von Scheinwerfern spielt jedoch die Bauraumproblematik eine große Rolle, da insbesondere vertikaler Bauraum aufgrund der CW-optimierten Gestaltung von Fahrzeugkarosserien stark begrenzt ist. Darüber hinaus ist auch der horizontale Bauraum in Scheinwerfern durch die Anzahl der vorzusehenden Scheinwerfer und die zu leistenden Lichtstärken stark beschränkt.The connection using a sealant has the disadvantage of requiring more space, which means that the already limited installation space in the body cannot be used optimally. However, the installation space problem plays a major role in the design of headlights, as vertical installation space in particular is very limited due to the CW-optimized design of vehicle bodies. In addition, the horizontal installation space in headlights is also very limited by the number of headlights to be provided and the light intensities to be provided.

Darüber hinaus entstehen bei der Verwendung von Dichtmitteln große Fugen zwischen Abdeckscheibe und Kotflügel bzw. Stoßfänger oder Motorhaube etc.In addition, the use of sealants creates large gaps between the cover panel and the fender or bumper or bonnet, etc.

Beim alleinigen Einsatz von Klebstoffen bestehen darüber hinaus technologische Nachteile, da eine gewisse Aushärtzeit stets vonnöten ist, binnen derer sich die Teile gegeneinander bewegen können.There are also technological disadvantages when using adhesives alone, as a certain curing time is always necessary, during which the parts can move against each other.

In dieser Zeit müssen die Teile, um ein sicheres und dichtes Verbinden zu gewährleisten, zwischengelagert, eventuell sogar gegeneinander verspannt werden, um eine Relativbewegung der Teile zu verhindern. Hierfür ist jedoch ein gewisser Platzbedarf in der Montage notwendig, der möglichst vermieden werden soll. Darüber hinaus können die Teile auch nicht unmittelbar weiterverarbeitet werden, was generell als ungünstig zu bewerten ist.During this time, the parts must be stored temporarily to ensure a secure and tight connection, and may even be braced against each other to prevent relative movement of the parts. However, this requires a certain amount of space in the assembly, which should be avoided if possible. In addition, the parts cannot be processed further immediately, which is generally considered to be disadvantageous.

Darüber hinaus bestehen bei den bisher eingesetzten Schweißverfahren, nämlich dem Vibrations-, dem Heizelement- und dem Ultraschallschweißen Nachteile hinsichtlich der geometrischen Auslegung der Bauteile, der Belastung durch Vibration und das schlechte Design der Schweißnaht beim Vibrationsschweißen. Darüber hinaus ist beim Ultraschallschweißen die Schweißnahtlänge begrenzt und es kann zur Freisetzung von Schweißpartikeln kommen.In addition, the welding processes used to date, namely vibration, heating element and ultrasonic welding, have disadvantages with regard to the geometric design of the components, the stress caused by vibration and the poor design of the weld seam in vibration welding. In addition, the weld seam length is limited in ultrasonic welding and welding particles can be released.

Die Erfindung soll nun einen Scheinwerfer bereitstellen, bei dem die dichte Verbindung zwischen Abdeckscheibe und Gehäuse auf platzsparende und hinsichtlich der Fertigung einfache Weise realisiert werden kann.The invention is now intended to provide a headlight in which the tight connection between cover plate and housing can be realized in a space-saving and simple manner in terms of production.

Die Erfindung löst diese Aufgabe durch die gestalterische Auslegung der Verbindungsstelle, nämlich dadurch, dass das Gehäuse eine zumindest abschnittsweise umlaufende U-förmige Kontur zur Aufnahme einer Kante der Abdeckscheibe aufweist und wobei im Bereich der Kontur des Gehäuses das Gehäuse mit der Abdeckscheibe verschweißbar ist. Als Schweißverfahren kann hierbei insbesondere ein Laserschweißverfahren und insbesondere ein Durchstrahllaserverfahren vorgesehen sein, wobei hierbei die Anzahl der Diodenlaser dem Umfang, der zu verschweißen ist, entspricht.The invention solves this problem by the design of the connection point, namely by the housing having a U-shaped contour that runs around at least part of the connection point to accommodate an edge of the cover plate, and the housing can be welded to the cover plate in the area of the contour of the housing. A laser welding process and in particular a transmission laser process can be provided as the welding process, the number of diode lasers corresponding to the circumference that is to be welded.

Auf diese Weise wird eine hohe Anmutungsqualität der Schweißverbindung erreicht und der zur Verfügung stehende Einbauraum optimal genutzt. Die Kante der Abdeckscheibe verläuft hierbei sicher geführt innerhalb der U-förmigen Kontur und wird durch die beiden Schenkel der U-förmigen Kontur umschlossen.In this way, a high quality of appearance of the welded joint is achieved and the available installation space is used optimally. The edge of the cover plate runs safely within the U-shaped contour and is enclosed by the two legs of the U-shaped contour.

Ein von außen sichtbarer Spalt entsteht auf diese Weise nicht. Die Scheinwerfergeometrie wird auch nicht vergrößert durch aufwändige Halte- und Sicherungselemente.This means that there is no gap visible from the outside. The headlight geometry is also not enlarged by complex holding and securing elements.

Es kann dabei insbesondere vorgesehen sein, dass das Scheinwerfergehäuse und die Abdeckscheibe aus thermoplastischem Kunststoff bestehen. Insbesondere kann die Abdeckscheibe aus transparentem Kunststoff und das Gehäuse, das auch in Form eines Zwischenrahmens ausgebildet sein kann, aus einem farbigen, insbesondere dunkel gefärbten Kunststoff ausgeführt sein.In particular, it can be provided that the headlight housing and the cover plate are made of thermoplastic material. In particular, the cover plate can be made of transparent plastic and the housing, which can also be designed in the form of an intermediate frame, can be made of a colored, in particular dark-colored, plastic.

Dabei kann zwischen der U-förmigen Kontur und der Kante ein Abstand zur Aufnahme der Schmelze vorgesehen sein. D. h. der Boden der U-förmigen Kontur ist breiter als die aufzunehmende Kante der Abdeckscheibe, so dass die Abdeckscheibe in der Kontur mit Spiel geführt ist.A gap can be provided between the U-shaped contour and the edge to accommodate the melt. This means that the base of the U-shaped contour is wider than the edge of the cover plate to be accommodated, so that the cover plate is guided in the contour with play.

Nach einer besonders vorteilhaften Ausgestaltung kann darüber hinaus in der U-förmigen Kontur eine Dichtnut vorgesehen sein, in die ein Dichtsteg der Abdeckscheibe, der korrespondierend zur Dichtnut ausgebildet ist und an der Kante der Abdeckscheibe angeordnet ist, eintaucht. Der Dichtsteg kann dabei eine geringere Breite als die Kante der Abdeckscheibe aufweisen. Es kann hier bspw. als Dichtmittel eine Dichtschnur oder Ähnliches eingebracht werden.According to a particularly advantageous embodiment, a sealing groove can also be provided in the U-shaped contour, into which a sealing web of the cover plate, which is designed to correspond to the sealing groove and is arranged on the edge of the cover plate, dips. The sealing web can have a smaller width than the edge of the cover plate. A sealing cord or something similar can be introduced here as a sealing agent, for example.

Des weiteren können in eine U-förmige Kontur zur Aufnahme von Dichtmittel oder Kleber Positionierrippen und Schweißstege eingebracht werden.Furthermore, positioning ribs and welding webs can be incorporated into a U-shaped contour to accommodate sealant or adhesive.

Die Schweißstege sind so ausgelegt, dass sie im Dichtmittel oder Kleber eingebettet sind.
35The welding bridges are designed to be embedded in the sealant or adhesive.
35

Die Schweißstege sind gegenüber den Auflagestegen um den Betrag der Abschmelzhöhe erhaben ausgelegt.The welding bars are raised above the support bars by the amount of the melting height.

Je nach Umfang der Dichtkontur kann die Anzahl der Schweißstege gewählt werden.The number of welding bars can be selected depending on the size of the sealing contour.

Bei großen Konturtoleranzen zwischen Fuß der Abdeckscheibe und Dichtbett kann diese Kombination der partiellen Verschweißung mit umlaufender Abdichtung angewendet werden. 10In the case of large contour tolerances between the base of the cover plate and the sealing bed, this combination of partial welding with circumferential sealing can be used. 10

Dies kann auch bei vorhandenen Dichtsystemen angewandt werden.This can also be applied to existing sealing systems.

Fig. 1 zeigt einen Ausschnitt aus einem Scheinwerfer im Schnitt umfassend eine Abdeckscheibe 1 sowie ein Gehäuse Das Gehäuse 2 ist mit der Abdeckscheibe 1 dicht verbunden. Das Gehäuse 2 weist hierfür eine U-förmige Kontur 9 auf, die als Aufnahme für eine Kante 11 der Abdeckscheibe 1 dient. Die Abdeckscheibe 1 weist hierzu einen Vorsprung an ihrer dem Scheinwerferinneren zugewandten Seite auf, der mit 12 bezeichnet ist. An der dem Äußeren des Scheinwerfers zugewandten Seite der Abdeckung 1 bildet die Kante 11 dadurch eine Stufe 8, die mit einem äußeren Schenkel 3 der U-förmigen Kontur 9 korrespondiert. Auf diese Weise ist die Abdeckscheibe 1 mit ihrer Kante 11 in der U-förmigen Kontur 9 geführt. Durch die U-förmige Kontur, insbesondere den äußeren Schenkel 3 der U-förmigen Kontur ist ein Fangsteg für die Schmelze beim Laserschweißen und gleichzeitig eine Schweißbegrenzung gegeben.Fig. 1 shows a section of a headlight comprising a cover plate 1 and a housing. The housing 2 is tightly connected to the cover plate 1. The housing 2 has a U-shaped contour 9 for this purpose, which serves as a holder for an edge 11 of the cover plate 1. The cover plate 1 has a projection on its side facing the interior of the headlight, which projection is designated by 12. On the side of the cover 1 facing the outside of the headlight, the edge 11 thereby forms a step 8 which corresponds to an outer leg 3 of the U-shaped contour 9. In this way, the cover plate 1 is guided with its edge 11 in the U-shaped contour 9. The U-shaped contour, in particular the outer leg 3 of the U-shaped contour, provides a catch web for the melt during laser welding and at the same time a welding limit.

Zwischen dem äußeren Schenkel 3 und dem Steg 12 der Kante 11 ist ein Abstand 7 vorgesehen, der so groß ausgebildet ist, dass die Schmelze Platz findet.Between the outer leg 3 and the web 12 of the edge 11, a distance 7 is provided which is large enough to accommodate the melt.

Fig. 2 beschreibt nun eine alternative Ausgestaltung, bei der in der U-förmigen Kontur 9 eine Nut 4 vorgesehen ist, in die ein Dichtmittel 5, insbesondere eine Dichtschnur, eingebracht werden kann. Das Dichtmittel 5 wird dabei vor dem Schweißprozess in die Nut 4 eingebracht. Die Nut 4 läuft zusammen mit der U-förmigen Kontur 9 um.Fig. 2 now describes an alternative embodiment in which a groove 4 is provided in the U-shaped contour 9, into which a sealing agent 5, in particular a sealing cord, can be introduced. The sealing agent 5 is introduced into the groove 4 before the welding process. The groove 4 runs together with the U-shaped contour 9.

Im Gegenzug dazu weist die Kante 11 der Abdeckscheibe 1 neben dem Steg 12, in dessen Bereich die Verschweißung über die Schmelze 10 vorgenommen wird, mit dem Gehäuse 2 eine Dichtnase 6 auf, die dem Scheinwerferinneren 13 zugewandt ist und die mit der Nut 4 korrespondiert und so ausgebildet ist, dass sie mit dem Dichtmittel 5 ebenfalls in Kontakt steht und in dieses eintaucht.In contrast, the edge 11 of the cover plate 1 has, next to the web 12, in the area of which the welding is carried out via the melt 10, a sealing nose 6 with the housing 2, which faces the headlight interior 13 and which corresponds to the groove 4 and is designed such that it is also in contact with the sealing agent 5 and is immersed in it.

Figuren 3 und 4 zeigen eine übliche U-förmige umlaufende Kontur 9 vom Dichtbett des Gehäuses 2, in der auf Positionierrippen 14 die Kante 11 der Abdeckscheibe 1 nach dem Abschmelzen aufliegt und in Höhe positioniert ist.Figures 3 and 4 show a conventional U-shaped circumferential contour 9 of the sealing bed of the housing 2, in which the edge 11 of the cover plate 1 rests on positioning ribs 14 after melting and is positioned in height.

Neben den Positionierrippen 14 sind die Schweißstege 16 mit ihrem Schmelzbereich 10 in den U-förmigen Kanal des Gehäuses 2 eingebracht.
10In addition to the positioning ribs 14, the welding webs 16 with their melting area 10 are introduced into the U-shaped channel of the housing 2.
10

Auf diese Weise kann insbesondere bei komplizierten und verschachtelten Geometrien die Dichtheit verbessert erzeugt werden.In this way, the tightness can be improved, especially in the case of complicated and nested geometries.

Der Schweißprozess selbst findet dann über einen Durchstrahllaser statt, bei dem entsprechend dem Umfang eine bestimmte^Anzahl Diodenlaser vorgesehen ist.The welding process itself then takes place via a transmission laser, in which a certain number of diode lasers are provided depending on the circumference.

Auf diese Weise kann die Bauteilbelastung beim Fügeprozess verringert werden und der Bauraum wird optimal genutzt.In this way, the load on the component during the joining process can be reduced and the installation space is used optimally.
