Headlamp Device for a Tilting Vehicle, and Tilting Vehicle Comprising Such a Headlamp Device

Abstract

A headlamp device for a tilting vehicle includes an optical housing which has a cavity that is accessible from the outside via an opening; an illuminant which is located in the cavity of the optical housing and through which electromagnetic waves can be emitted in the visible and/or invisible range; a cover unit which can be fixed or is fixed to the optical housing so as to overlay the opening of the optical housing, in particular in its entirety, in order to outwardly delimit the cavity together with the optical housing. The cover unit includes a transparent and/or translucent optical element which is optically downstream of the illuminant and which is optically transparent to the electromagnetic waves of the illuminant; an opaque cover element which is optically opaque to the electromagnetic waves of the illuminant; and a common single-piece component formed by the optical element and the cover element.

DETAILED DESCRIPTION OF THE DRAWINGS

[0034] The figures show an exemplary embodiment of a headlamp device, provided in its entirety with the reference sign 2, for a tilting vehicle (not shown in the figures). The headlamp device 2 comprises at least one optics housing 4, which comprises at least one cavity 6 which is accessible from the outside via an opening. Arranged in the cavity 6 of the optics housing 4 is a light-emitting device (not shown in the figures). The light-emitting device can emit electromagnetic waves in the visible and/or invisible range, in particular light or infrared radiation.

[0035] Moreover, the headlamp device 2 comprises a cover unit 8, which is secured to the optics housing 4, with the opening in the optics housing being overlaid in its entirety. Together with the optics housing 4, the cover unit 8 bounds the cavity 6 in its entirety toward the outside.

[0036] The cover unit 8 comprises a transparent and/or translucent optical element 10, which, in the exemplary embodiment shown in the figures, overlays the opening in the optics housing 4 in its entirety. The optical element 10 is optically connected downstream of the light-emitting device and is optically transmissive to electromagnetic waves from the light-emitting device.

[0037] Moreover, the cover unit 8 comprises an opaque shielding element 12, which is optically opaque to the electromagnetic waves from the light-emitting device. In the exemplary embodiment shown in the figures, the shielding element 12 is arranged at a peripheral section facing the optics housing, overlays part of the optical element 10, and forms two viewing windows 14. In the exemplary embodiment shown in the figures for the headlamp device 2, the cover unit 8 is formed by a common one-piece component formed from the optical element 10 and the shielding element 12. The optical element 10 and the shielding element 12 here comprise a plurality of plastics components, which form the cover unit 8 during a multi-component injection molding process.

[0038] The figures show an exemplary embodiment of the headlamp device 2, in which an additional shield 16 is provided, which is arranged in the cavity 6 and is formed as a separate or separable component. The additional shield 16 is secured to the shield element 12 of the cover unit 8 and is contactlessly at a distance from the optical element 10.

[0039] In order to secure the additional shield 16 to the shielding element 12, the shielding element 12 comprises a receptacle 18 in which the additional shield 16 is arrangeable with a joining section 20 and orientable in relation to the cover unit 8.

[0040] The features of the invention that are disclosed in the previous description, in the claims and in the drawing can be essential, both individually and also in any desired combination, in the implementation of the invention in its various embodiments.
