Definitions

  • the invention relates to a method for fastening a lens for a motor vehicle headlight to a motor vehicle headlight housing.
  • a cover lens for a motor vehicle headlight is fastened to a motor vehicle headlight housing provided for this purpose by means of vibration welding, it being important to ensure that a minimum distance is maintained in all spatial planes between parts that are not to be welded.
  • Headlights in particular, which are intended to generate at least two light functions or light distributions, are constructed in such a way that, in the best case, an at least optically closed chamber is provided for each light function.
  • FIG. 1 and 2 jointly show a method for fastening a cover lens 100 for a motor vehicle headlight 10 to a motor vehicle headlight housing 200, wherein in a first step a) a motor vehicle headlight housing 200 is provided, wherein in the motor vehicle headlight housing 200 a first light module 210, which contributes to the generation of a first light distribution, and a second light module 220, which contributes to the generation of a second light distribution, is arranged.
  • the motor vehicle headlight housing 200 comprises a screen 230 which is arranged between the first and second light module 210, 220 , the screen 230 being arranged in such a way that the direct coupling of light emitting from one of the light modules 210, 220 into another light module is prevented.
  • a holding body is provided, on which the first and second light modules 210, 220 and the panel 230 are arranged, the holding body, the first and the second light module 210, 220 and the panel 230 forming an assembly, and the assembly in the motor vehicle headlight housing 200 can be brought into an assembly position P1 and into an end position P2 that differs from the assembly position P1 .
  • a lens 100 which has a first projection section 110 and a second projection section 120 , which first and second projection sections 110, 120 are at least partially translucent, the first projection section 110 being assigned to the first light module 210 and set up in combination with the first light module 210 is to generate the first light distribution, and wherein the second projection section 120 is assigned to the second light module 220 and is set up in combination with the second light module 220 to generate the second light distribution.
  • the cover lens 100 also has an opaque section 130 , which is arranged between the first and second projection sections 110 , 120 and is set up to optically and spatially separate the first and second projection sections 110 , 120 from one another, so that the light coupled into a projection section is prevented from to couple the other projection section.
  • step b) the assembly is transferred to the assembly position P1 with respect to the motor vehicle headlight housing 200 , which assembly position P1 in 1 is shown, with the assembly being pre-positioned in the assembly position P1 in such a way that the cover 230 is free of mechanical contact with the opaque section 230 of the cover lens 100 during the subsequent fixing of the cover lens 100 in a fixing position on the motor vehicle headlight housing 200 in accordance with step c). , ie the aperture 230 does not reach Plant on the opaque portion 130 of the lens 100 when the lens 100 is applied to the motor vehicle headlight housing 200 for fixing.
  • the cover lens 100 is transferred to the motor vehicle headlight housing 200 in the fixing position and then fixed to the motor vehicle headlight housing 200 by means of vibration welding.
  • step d) the assembly is transferred to the end position P2 , which end position P2 in 2 is shown, with the assembly being arranged in the end position P2 in such a way that the screen 230 extends continuously to the opaque section 130 and is in mechanical contact with the opaque section 130 of the cover lens, so that light from one light module is coupled into one of the other Light module associated projection section 110,120 of the lens 100 is prevented.
  • the assembly is transferred into the assembly position P1 in step b) and into the end position P2 in step c) by means of adjusting screws, which are accessible from outside the motor vehicle headlight housing 200 .
