Definitions

  • the invention relates to a projection module for a vehicle headlamp with a reflector, with a reflector associated with the reflector lens, with a reflector disposed in the emission direction of the lens, with a arranged between the light source and the lens fixed high-beam diaphragm, one of the high-beam diaphragm to the lens out to produce asymmetric dipped beam in the beam path swiveling control panel and a front of the high-beam diaphragm additional panel for the generation of symmetrical dipped beam.
  • a projection module for vehicle headlights which has a reflector with a light source associated with it in the beam path, a lens is arranged. Between the reflector and the lens, a fixed high-beam diaphragm is arranged transversely to the longitudinal axis in a vertical first plane. The high-beam diaphragm is preceded by a transverse to the longitudinal axis in the beam path einschwenkbare switching diaphragm for generating an asymmetric low beam towards the lens.
  • the switch panel is connected via a bearing, which consists essentially of a mounted on the high beam aperture bearing axis, rotatably connected via a special attachment part for axial position assurance with the high-beam diaphragm.
  • a bearing which consists essentially of a mounted on the high beam aperture bearing axis, rotatably connected via a special attachment part for axial position assurance with the high-beam diaphragm.
  • an additional panel is arranged to produce symmetrical low beam for a so-called tourist solution.
  • a disadvantage of this arrangement which has proven itself in principle, is that the arrangement of the additional panel between the control panel and the high-beam diaphragm by maintaining safety distances and reduce friction, a relatively large length is created. Furthermore, the use of several items and their arrangement of the cost, in particular by the installation is relatively high. Should on the tourist solution or the additional panel be waived, in particular, the main beam and the control panel must be designed differently, resulting in increased storage. Object of the present invention is therefore to improve the known projection module so that the length and cost is reduced.
  • the additional aperture of the switching diaphragm is arranged in front of the lens, the distance between the switching diaphragm and the high-beam diaphragm is lower, as a result of which the overall length of the projection module can be reduced overall.
  • the additional panel can be made very inexpensive. According to customer-specific requirements, the tourist solution can be dispensed with by simply not assembling if necessary. The number of varieties and the associated increased storage is thereby reduced.
  • the additional panel on a passage, with which it is stored in a hole of the tab.
  • the side flap of the main lens hood has two of the bore at a distance adjacent arms, in which the additional panel is supported. At the additional panel impressions are arranged adjacent to the arms.
  • the additional panel on an integrated spring which in the mounted state in two locking positions detent via an adjacent cam, which is stamped out of the tab of the high-beam diaphragm, slides.
  • the integrated spring detent Due to the integrated spring detent is achieved without additional part, with a secure fit of the additional panel or the light finger is achieved in a pivoted in the beam path active and in a swung-out inactive position.
  • the additional panel in its pivoted active position strikes against a stop arranged on the high-beam diaphragm with a top edge in the vertical direction.
  • the switch panel is pivotable in a second plane, which is arranged at an angle in the vertical direction to a first plane formed by the main beam aperture.
  • the second plane is arranged at an angle to the first plane, there is an inclination of the switching diaphragm, which makes it possible that both diaphragms can be arranged as close to the xenon burner of the light source.
  • This allows a minimum possible module length, taking into account in particular the safety against sparkover. Taking into account the required distance of the aperture to the lens thus a minimized short length can be realized.
  • Due to the inclination of the control panel it is also possible to pivot the control panel relatively low friction.
  • the high-beam diaphragm is arranged with its Fernlichtblendenkante to the light source in a distance corresponding to a minimum distance and the control panel with its upper aperture edge in the pivoted active state also approximately in the minimum distance arranged corresponding to the light source distance.
  • the aperture edges have a minimum distance to the lens in the active state.
  • a projection module 1 essentially consists of a reflector 2, a light source 3, a high-beam diaphragm 4, a switching diaphragm 5, an additional diaphragm 6 and a lens 7.
  • the projection module 1 is arranged in a headlight housing, not shown, of a motor vehicle.
  • the reflector 2 is formed ellipsoidal and has in its apex region a reflector opening 8, in which the light source 3 is arranged.
  • the reflector 2 can in principle also be designed as a free-form reflector.
  • the light source 3 is designed, for example, as a xenon burner.
  • the reflector 2 is connected to the fixed high-beam diaphragm 4.
  • the high-beam diaphragm 4 is thus arranged transversely to an approximately horizontal direction in the longitudinal axis 10 of the projection module 1 in an approximately vertical first plane 11.
  • the high-beam diaphragm 4 has a high-beam diaphragm edge 12 which serves to generate a bright-dark boundary of a high-beam beam.
  • the switch panel 5 is pivotally connected at its axle-side end 13 about a pivot axis 14 with the high-beam diaphragm 4.
  • the high-beam diaphragm 4 has a sleeve-shaped bearing element 15, onto which the switching diaphragm 5 can be plugged with a bearing sleeve 16.
  • the pivot axis 14, which coincides 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, is inclined in the vertical direction with respect to a vertical 17 to the first plane 11 by an angle 18.
  • the switching panel 5 is pivotable in a second plane 19, which is also inclined relative to the first plane 11 by the angle 17.
  • the high-beam diaphragm 4 is curved in a central region 20 in the horizontal direction to the light source 3 out.
  • the switching panel 5 is also curved towards the light source 3.
  • the control panel 5 is guided in a guide 22 of the high-beam diaphragm 4.
  • the high-beam diaphragm 4 a stop 23, against the striker 5 abuts with its upper bezel edge 24 in its active position.
  • the control panel 5 is used to produce a low beam with asymmetric cut-off.
  • the upper panel edge has the same horizontal distance 25 to the light source 3 and the same minimum distance to the lens 7 as the Fernlichtblendenkante 12.
  • the switching panel 5 is connected to an electric adjuster 28 and drive.
  • the additional panel 6 is the switch panel 5 upstream of the lens 7 out. Via an integrally formed angled lever 29, the additional panel 6 is mounted on a side flap 30 of the high-beam diaphragm 4 and pivotable about an approximately horizontal direction transverse to the longitudinal axis 10 or optical axis of the projection module 1 arranged pivot axis 31.
  • the pivot axis 31 of the additional diaphragm 6 is arranged between the high-beam diaphragm 4 and the reflector opening 8 or a lamp holder 32 of the light source 3.
  • the lateral tab 30 has two arms 33, 34, in which the additional panel 6 is supported.
  • the additional panel 6 has a passage 35 with an out of the lever 29 to the tab 30 outstanding collar, which is mounted in a bore 36 of the tab 30.
  • the additional panel 6 has the arms 33, 34 adjacent to the arms 33, 34 impressions impressions 37, so that the additional panel 6 is mounted without play and with secure fit on the tab 30.
  • the additional panel 6 has an integrated spring 38, which slides in the assembled state via an adjacent cam 39 of the tab 30 and engages in two locking positions. With an upper edge 40 in the vertical direction, the additional panel 6 strikes in its active position pivoted into the beam path against a second stop 41 arranged on the main beam 4.
  • the additional panel 6 is used to produce a low beam with symmetrical cut-off.
  • the additional diaphragm 6 is superimposed with a screening finger 42 or its diaphragm edge 43 upper aperture edge 24 of the control panel 5, so that there is a low beam with symmetrical cut-off.
  • the blend edge 43 of the additional panel 6 is preferably held at a shorter distance from the lens 7 than the edges 12, 24 of the panels 4, 5.
