Definitions

  • the invention relates to a headlight for vehicles with an intermediate a cup-shaped diaphragm arranged on a reflector and a lens, which are both used to shield directly from a light source Light rays as well as covering the light source and its bottom is a lid connected to its peripheral side wall, and with at least one support element, which the cup-shaped panel with the Reflector connects.
  • Such a headlight for vehicles is known from DE 195 14 085 A1.
  • the headlight has a pot-shaped housing made of plastic on, which is closed on its front by a lens. Inside the housing is a bowl-shaped plastic Arranged reflector. There is an opening in the apex area of the reflector introduced to accommodate a light bulb.
  • the light bulb dips with hers Glass flask into a cup-shaped cover.
  • As the bottom of the cup-shaped A cover serves as a cover, which is integral with the peripheral side wall of the panel is connected.
  • the lid borders its outer edge section to the outer facing the lens Edge of the side wall.
  • the cover is made of sheet metal and consists of practice mostly made of sheet steel, so that the aperture of the high Withstands heat from the light bulb.
  • the cup-shaped aperture is connected to the reflector via three arm-shaped support elements.
  • the Side wall of the panel is punched out of sheet metal and into a hollow body rolled and has a seam through blunt edges is formed.
  • the disadvantage here is that with an optics-free lens Interior of the headlamp due to the cover made of sheet steel appears inhomogeneous. With a cover made of sheet steel and on the outside is chrome-plated, the chrome plating runs at a high Colored heat load.
  • the headlights can be made of a different material than the headlights
  • Sidewall of the panel can be made, however, is the outer edge portion the circumferential side wall of the cup-shaped screen from the outside disturbing visible.
  • the object of the invention is that in the preamble of claim 1 described headlights to improve so that the entire Outside of the cup-shaped bezel from a bare surface having and easily deformable sheet metal is intended for the cup-shaped panel given a high heat load and dimensional stability is.
  • This object is achieved according to the invention in that the cup-shaped aperture all the way to its outer free edge has extending double-walled side wall and her as the bottom serving cover and the outer wall part of the side wall from the same Made of sheet metal. This can cover the entire outside of the bezel from one Be formed sheet, which after its shaping a smooth outside has to contribute to the dimensional stability of the cup-shaped aperture and with the persistent tarnish on the smooth outside of the panel occur at temperatures that are higher than with chrome Sheet steel.
  • a particularly suitable sheet for the panel Light metal sheet with a silver colored shiny surface, which as Outside serves for the bezel.
  • the light metal sheet is made advantageously made of aluminum or an aluminum alloy, the silver-colored shiny surface is protected by a film.
  • the shiny surface forms the outside of the cup-shaped cover. To the shaping of the outer wall part and the bottom of the panel is only the Slide removed. As a result, the outside of the panel cannot be molded to be damaged.
  • a very deep design of the cup-shaped cover is possible if the outer and inner circumferential wall part of the side wall each have a seam has, which from the outer edge facing the reflector up to runs the outer edge facing the lens.
  • the outer wall part is not deep-drawn, but can be rolled. At the Deep drawing is created on the outside of the outer wall part undesirable matt surface.
  • the smooth surface remains of the outer wall part even if the circumferential side wall the cup-shaped aperture is almost cylindrical.
  • the aperture builds on one cylindrical shape very small. This allows the optically effective Reflection area of the reflector in the area of its apex as large as possible fail.
  • the form stability of the panel is particularly great when the inner and outer wall part is frustoconical.
  • the aperture points from the outside a homogeneous appearance when the inner and outer Wall part has a common edge. Only the inner wall part of the side wall for shading directly from the light source emerging light rays.
  • the inner wall part is made of sheet steel and a matt inner surface having.
  • the matt inner surface can be formed by a black paint his. This ensures high light absorption and therefore none disturbing light rays arise from reflection within the aperture.
  • the cover is given a high level of shape stability, since it is made of sheet steel is made.
  • the support element of the panel is double-walled is executed and each part of the support element to one of the seam bounding edges of the inner wall part is integrally connected, wherein the support member through a slot of the outer wall part passes through and the slot is only open to the side of the reflector.
  • the outer wall part is with sections of its outer edges by small Impressions firmly connected to the inner wall part.
  • the headlight has an outer casing made of plastic, which is completed by a largely optics-free lens (not shown). At least one is off inside the outer casing Plastic, bowl-shaped reflector (1) arranged.
  • the reflector (1) is an opening (17) for receiving in the region of its apex a light source (3) introduced.
  • An incandescent lamp serves as the light source (3), which with its glass bulb (18) ahead through the opening (17) of the reflector (1) is inserted until the light bulb with its plate-shaped base (19) abuts the outer edge region of the opening (17).
  • the base (19) is through a holding device, not shown, on the rear of the reflector (1) supported.
  • the incandescent lamp has a filament, which in one Focal area of the bowl-shaped reflector (1) is arranged.
  • the Glass bulb of the incandescent lamp has one at its front free end section blackened cap (20) to exit directly from the light source (3) Shield light rays from the back. So that front edge portions of the Reflector (1) against light rays, which come directly from the light source (3) emerge, are shielded, the glass bulb (18) dips with its free end into a cup-shaped diaphragm (2) which is connected to the Reflector (1) is connected.
  • the cup-shaped cover (2) has a double-walled all around Side wall (5) and a bottom (4), which is formed by a lid is.
  • the inner wall part (10) of the double-walled side wall (5) consists of a sheet steel, the inside of which is painted black.
  • the black one Painting serves to absorb the inside of the inner wall part (10) occurring light rays from the light source (3).
  • Figure 5 is the inner one Wall part (10) shown unwound and points to its facing away Edges (13) each have a support arm, which doubles the support element (6) is. After the inner wall part (10) has rolled, the edges delimit (14) a seam (16) that also between the two arms of the doubled support element (6).
  • FIG. 6 is the outer wall part (9) of the side wall (5) of the cup-shaped cover (2) shown.
  • the outer wall part (9) and the base (4) serving as a lid the panel (2) are formed from a light metal sheet, the The outside of the cup-shaped cover (2) is a high-gloss surface and is silver colored. The high-gloss surface is through a peelable film protected. The film is only after molding the outer Wall part (9) and the bottom (4) deducted.
  • the outer wall part (9) just like the inner wall part (10) rolled and lies flat against the inner one Wall part (10).
  • the outer wall part (9) is on its front Edge (12) by indentations, which in the surface of the inner Engage wall part (10), held on the inner wall part (10).
  • At the front edge (12) has the inner and outer wall part (10 and 9) all around a step in which a lateral edge section (8) of the Bottom (4) is arranged.
  • the lateral edge section (8) runs with it
  • the outside is flush with the outside of the adjacent outer wall part (9).
  • the lid (4) serving as a cover is also not shown Impressions on the outer wall part (9) held captive.
  • the inner one and the outer wall part (10 and 9) have a common edge all around (7) on. Only the edge (7) of the inner wall part (10) serves here for shading light rays emerging directly from the light source (3).
  • the bottom (4) of the cup-shaped cover (2) does not have to be like its side wall (5) be double-walled because of the blackened cap (20) of the Glass bulb (18) of the light source (3) opposite the floor directly from the Light source (3) emerging light rays is shielded.
  • FIG. 7 The development shown in FIG. 7 is the outer one Wall part (9) and the bottom (4) of the cup-shaped cover (3).
  • the Bottom (4) in one piece with the outer wall part (9) via a bending tab (13) connected.
