Definitions
- the invention relates to a vehicle headlight with a reflector, the in Radiation direction is a radiation shield shielding a lamp, wherein the radiation diaphragm has at least two support arms for connecting the Radiation diaphragm with the edge area of a reflector opening.
- DE 36 24 131 A1 describes a vehicle headlight with a radiation diaphragm known, which is inserted from behind through the receptacle of the reflector and is attached to a rear reflector neck of the reflector.
- the Radiation diaphragm has two support arms oriented opposite to the direction of radiation on the free ends of which a flange is arranged.
- the flange has a bore within which there is a bore Screw extends into the inside of a threaded hole of the adjacent Reflector neck '.
- a positioning pin is also provided on the reflector neck for correct positioning of the flange.
- a disadvantage of the known Vehicle headlights is the complex assembly of the radiation shield on the Reflector neck.
- EP 0 718 545 A1 describes a vehicle headlight with a radiation diaphragm known, on the one hand, from an elongated cylindrical diaphragm part and on the other hand, there is a part shielding the directly emitted light.
- a disadvantage of the known vehicle headlights, which is due to the two-part design of the radiation diaphragm increased assembly effort necessary is.
- DE 41 26 044 C3 describes a vehicle headlight with a radiation diaphragm known, which is made from a single stamped part.
- the radiation shield has two opposite ones oriented opposite to the radiation direction Support arms, the free ends of which each have a U-shaped end section have that in at the front and back of a reflector neck engage arranged recesses. By bending the free end of the end portion about a transverse wedge-shaped The neck of the reflector is attached to the radiation shield on the back of the Reflector neck firmly connected to this.
- a disadvantage of the known Vehicle headlights is that the assembly of the radiation shield relatively expensive is.
- the object of the present invention is therefore the known Improve vehicle headlights so that the assembly of the radiation shield on the reflector is simplified.
- the diaphragm is a Retaining spring is associated with and under tension in the transverse direction spring arms extending in the longitudinal direction.
- the advantage of the invention is in particular that by the retaining spring a clamping or latching connection of the support arms with the reflector neck is made possible.
- To mount the radiation shield it is only necessary to Push the support arms inwards so far that the ends of the support arms into the engage through the opening formed by the reflector neck and join an inner Edge of the reflector neck.
- the snap lock thus formed enables quick and easy attachment and removal of the Radiation shield on the reflector neck.
- the Spring arms of the retaining spring on an inside of the support arms and thus cause radially outward clamping forces that the support arms on the Hold the reflector neck.
- the Radiation aperture on a dome and is made in one piece from a shiny Made of aluminum sheet, so that it is reliably prevented Incandescent lamp is visible from the outside through the clear cover plate. Also results an aesthetically pleasing impression.
- a Stiffening section of the retaining spring at right angles to the spring arms and runs in the transverse direction to the radiation diaphragm, with a central section being spaced apart and extends parallel to a plane formed by the spring arms.
- the support arms are hook-shaped Ends, on the inside facing the middle section the free end of the spring arm presses. This creates a targeted pressure point on the Exercised inside of the hook-shaped end, so that the support arms engage can intervene the reflector approach.
- a vehicle headlight consists essentially of a housing part (1) for Inclusion of a reflector (2) with an incandescent lamp (3) and a cover plate (4).
- the reflector (2) is assigned a radiation diaphragm (5) which is used for Shielding part of the light emitted by the incandescent lamp (3) is used.
- the radiation diaphragm (5) is essentially coaxial with an optical axis (6) of the reflector (2) arranged.
- the radiation shield (5) faces the cover plate (4) towards a dome (7) arranged transversely to the optical axis (6).
- the dome (7) is connected to the reflector (2) by two opposite support arms (8) connected.
- the radiation diaphragm (5) is made in one piece Stamped part (9) manufactured.
- the stamped part (9) is made of a sheet metal material, especially made of a high-gloss aluminum sheet material.
- a plastic film made of anodised aluminum protects the surface high-gloss surface during the drawing or punching process.
- the stamped part (9) receives the for installation shape provided in the reflector (2).
- the dome (7) of the radiation diaphragm (5) is curved and concave towards the light bulb (3).
- the dome (7) enables the incandescent lamp (3) from the outside through the clear cover plate (4) is not visible. Due to the high-gloss surface of the dome (7), which for The surface of the reflector (2) corresponds to that which is visible from the outside Reflector surface a homogeneous appearance.
- the shading sections (10) form a tubular section adjoining the dome (7), the to shield one that is not desired for the formation of a low beam Partial light beam of the light bulb (3) is used.
- the Reflector (2) facing edges (11) of the shading sections (10) one on the Reflector (2) matched contour, so that the headlight described can only be used as a cornering light headlamp.
- the support arms (8) each have a hook-shaped at their free ends Element (12), each having a U-shaped recess (13) in the direction of has optical axis (6).
- the hook-shaped elements (12) are radial Resilient direction designed so that they can be compressed by pressing oppositely arranged support arms (8) with their recesses (13) press a peripheral edge of a reflector neck (14) and the radiation diaphragm (5) connect with the reflector neck (14) in a latching and clamping manner.
- a Retaining spring (15) provided with spring arms (16) on an inside of the Support arms (8) is mounted.
- the support arm (8) is in the transverse direction curved and has a retaining groove (17) in which the Federam (16) is stored.
- the elongated spring arms (16) are by a stiffening section (18) interconnected, which is transverse to the optical axis (6) in a plane in Area of the peripheral edge of the dome (7) extends.
- the stiffening section (18) has a plane parallel to the plane formed by the spring arms (16) extending middle section (19), each of which is symmetrical below Forming an obtuse angle connecting leg (20) to one extends dome-side end of the spring arm (16).
- the connecting legs (20) each form a right angle to the spring arms (16).
- the Stiffening section (18) serves to stiffen the radiation diaphragm (5) overall, in particular by investing the same in the area of a Bending line (21) this area is stabilized.
- the retaining spring (15) to the radiation diaphragm (5) in Position.
- the spring arms (16) extend in the direction of the reflector (2) easy opening, so that the hinge-like attached to the dome (7) Adapt the support arms (8) to this shape.
- the free ends of the spring arms (16) have inwardly directed lugs (22) which are located on the inside of a Extend leg of the hook-shaped element (12). Practice the noses (22) an outward pressure force, which is a safe and permanent Locking the hook-shaped elements (12) on the peripheral edge of the Effect reflector neck (14).
- the stamped part (9) points in one Support arms (8) oriented circumferential notches (23) on the edge form the bending line (21) and thus create a defined bending line.
- An alternative embodiment of the radiation diaphragm, not shown, can be used as Radiation shield for a high beam headlight. This aperture differs essentially from that described above in that the Shading sections (10) are omitted.
