Definitions

  • the invention relates to a projection module for a vehicle headlight a reflector, with a light source assigned to the reflector, with a Lens in front of the beam, with one between the light source and the lens arranged fixed high beam, one of the high beam upstream of the lens to produce asymmetrical low beam Switching panel that can be swiveled into the beam path and one of the high beam panels upstream additional aperture for generating symmetrical Dimmed headlights.
  • a projection module for vehicle headlights is known from DE 198 58 225 A1, which has a reflector with a light source assigned to it in its Beam path a lens is arranged. Between the reflector and lens is a fixed high beam diagonal to the longitudinal axis in a vertical first plane arranged. The high-beam diaphragm towards the lens is transverse to the longitudinal axis Switching panel that can be swiveled into the beam path to generate a asymmetrical low beam.
  • the control panel is a Storage, which essentially consists of a bearing axis attached to the high beam aperture exists, via a special fastening part for axial position securing rotatably connected to the main beam. Between high beam and control panel is for the generation of symmetrical low beam for a so-called Tourist solution arranged an additional aperture.
  • the disadvantage of this arrangement which has proven itself in principle, is that due to the arrangement of the additional cover between the switch cover and the high beam cover by maintaining safety distances and reducing friction a relatively large length is created. Furthermore, by using several Individual parts and, through their arrangement, the cost in particular due to the assembly relatively high. Should on the tourist solution or the additional cover the high beam cover and the switch cover in particular must be dispensed with run differently, which leads to increased storage.
  • the object of the present invention is therefore the known projection module to improve so that the overall length and cost are reduced.
  • the additional diaphragm of the switch diaphragm is positioned in front of the lens the distance between the control panel and high beam aperture is smaller, which makes the Overall length of the projection module can be reduced.
  • the additional screen a passage with which it is stored in a hole in the tab.
  • the side flap of the high beam cover has two of the holes at a distance adjacent arms in which the additional panel is held.
  • embossments are arranged adjacent to the arms.
  • the additional screen an integrated spring, which in the assembled state in two locking positions snapping over an adjacent cam, which from the tab of the High-beam aperture is embossed, glides.
  • control panel is pivotable in a second plane, which in the vertical direction to a arranged at an angle from the high beam aperture first plane is.
  • the second plane is arranged at an angle to the first plane, there is an inclined position of the control panel, which enables both panels can be arranged as close as possible to the xenon burner of the light source.
  • the bezel edges have a minimum distance to the lens in the active state.
  • the diaphragm edges towards the light source and the lens in one Minimum distance corresponding distance may be a minimum Overall length can be realized.
  • a projection module 1 essentially consists of a reflector 2, one Light source 3, a high beam cover 4, a switch cover 5, an additional cover 6 and a lens 7.
  • the projection module 1 is in a headlight housing, not shown Motor vehicle arranged.
  • the reflector 2 is ellipsoidal and has in its apex region a reflector opening 8 in which the Light source 3 is arranged. In principle, the reflector 2 can also be used as a free-form reflector be trained.
  • the light source 3 is, for example, a xenon burner educated.
  • the Reflector 2 At its front edge 9 facing the lens 7 is the Reflector 2 connected to the fixed high-beam aperture 4.
  • the high beam aperture 4 is thus transverse to a longitudinal axis running approximately in the horizontal direction 10 of the projection module 1 arranged in an approximately vertical first plane 11.
  • the high-beam diaphragm 4 has a high-beam diaphragm edge 12 which is used for generation a light-dark boundary of a high beam.
  • the control panel 5 is at its axis-side end 13 about a pivot axis 14 pivotally connected to the high-beam aperture 4.
  • the High-beam aperture 4 has a sleeve-shaped bearing element 15 on which the control panel 5 can be plugged on with a bearing sleeve 16.
  • the pivot axis 14 with the axis of symmetry of the bearing element 15 and in the assembled state with the Axis of symmetry of the bearing sleeve 16 coincides, is opposite in the vertical direction a perpendicular 17 to the first plane 11 inclined by an angle 18.
  • the control panel 5 can thus be pivoted in a second plane 19 is also inclined at an angle 17 with respect to the first plane 11.
  • the high beam aperture 4 is in a central region 20 in the horizontal direction to the light source 3 arched.
  • the control panel 5 is also curved toward the light source 3.
  • the switching screen 5 is guided in a guide 22 of the high-beam screen 4.
  • the high-beam diaphragm 4 has a stop 23 on its high-beam diaphragm edge 12, against which the switching diaphragm 5 strikes with its upper diaphragm edge 24 in its active position.
  • the control panel 5 In the swiveled-in active position, the control panel 5 is used to generate a low beam with an asymmetrical cut-off line.
  • the upper diaphragm edge has the same horizontal distance 25 from the light source 3 and the same minimum distance from the lens 7 as the high beam diaphragm edge 12.
  • the switching diaphragm 5 is connected to an electrical adjuster 28 or drive via an actuator 27.
  • the additional diaphragm 6 is arranged in front of the switching diaphragm 5 towards the lens 7.
  • About one molded angled lever 29 is the additional panel 6 on a side Tab 30 of the high-beam aperture 4 is mounted and about an approximately horizontal direction arranged transversely to the longitudinal axis 10 or optical axis of the projection module 1 Swivel axis 31 pivotable.
  • the pivot axis 31 of the additional panel 6 is between the high beam aperture 4 and the reflector opening 8 or one Lamp holder 32 of the light source 3 arranged.
  • the side tab 30 has two arms 33, 34, in which the additional panel 6 is held.
  • the additional panel 6 has a passage 35 with one from the Lever 29 protruding toward the tab 30, which in a bore 36th the tab 30 is stored.
  • the additional screen 6 has the arms 33, 34 adjacent on the arms 33, 34 adjacent impressions 37, so that the additional panel 6 backlash-free and securely seated on the tab 30.
  • the additional cover 6 has an integrated spring 38, which in the assembled state has a Adjacent cam 39 of the tab 30 slides and engages in two locking positions. With an upper edge 40 in the vertical direction, the additional cover 6 beats in their active position swung into the beam path against one on the High beam aperture 4 arranged second stop 41.
  • the additional diaphragm 6 is used to generate a low beam with a symmetrical light-dark boundary.
  • the additional diaphragm 6 overlaps the upper diaphragm edge 24 of the switching diaphragm 5 with a dimming finger 42 or its diaphragm edge 43, so that a dipped beam with a symmetrical light-dark boundary results.
  • dazzling oncoming traffic is avoided by pivoting the additional aperture 6 into the beam path. Because the additional diaphragm is formed only by the narrow anti-glare finger 42, this can remain in the beam path when the switching diaphragm 5 is switched to its deactivated position in order to generate the high beam.
  • the diaphragm edge 43 of the additional diaphragm 6 is preferably held at a shorter distance from the lens 7 than the edges 12, 24 of the diaphragms 4, 5.
