Definitions
- the present invention relates to a lighting projector for motor vehicle.
- the present invention relates more particularly to a lighting projector for a motor vehicle, comprising a light source, an elliptical type reflector, the first of which fireplace is arranged near the source and a second focal point is arranged in the vicinity of the focal plane of a lens converging, and a movable cover which is pivotally mounted, by relative to a fixed frame, around an axis generally transverse, and who is likely to occupy a position angular concealment, in which it is arranged substantially vertically in the vicinity of the focal plane of the lens so to form a cut in the light beam produced by the projector, and a retracted angular position, a spring requesting the movable cover in its concealed position.
- a electromagnet acts on the cover via a rod control, so as to cause the cover to pivot around a transverse axis, relative to its mount, from its angular position of concealment towards its angular position retracted.
- the cover is recalled elastically towards its position occultation by means of a spring and by the effect of a counterweight arranged in a portion of the cover located under its axis transverse pivot.
- the occultation position is defined by surfaces of stop of the cover which come into axial abutment against spans associated with the mount.
- the headlamp being intended for use in a vehicle automotive, it must be able to withstand the stresses thermal and mechanical specific to such use.
- the invention aims in particular to remedy this drawback.
- the invention provides a projector of the type described above, characterized in that it further comprises less a locking means intervening between the frame and the cover to hold the cover in its concealed position.
- a projector 10 for a motor vehicle which includes a lamp 12 mounted in the bottom of a reflector 14 of the elliptical type so that the light source, for example the filament of a lamp incandescence, where the electric arc of a discharge lamp, located in the vicinity of a first focus of the reflector 14.
- the light source for example the filament of a lamp incandescence, where the electric arc of a discharge lamp, located in the vicinity of a first focus of the reflector 14.
- the optical axis A-A is generally parallel to the axis longitudinal of the vehicle that the headlight 10 equips.
- the optical axis A-A is here substantially horizontal, and it can be defined for example by the two focal points of the reflector 14.
- the projector 10 includes a converging lens 18, for example plano-convex example, which is mounted at the front in a intermediate frame 20 fixed on a transverse surface front 22 of reflector 14.
- the focal plane of the lens 18 passes in the vicinity of the second focus of the reflector 14.
- the projector 10 includes a cover mobile 24 which is axially interposed between the reflector 14 and the intermediate frame 20, in the vicinity of the focal plane of the lens 18.
- the movable cover 24 is pivotally mounted relative to a mount 26, around a transverse axis B-B, between a angular position of concealment and an angular position retracted.
- the cache 24 In the angular position of concealment, which is shown in Figure 2, the cache 24 is contained overall in a vertical transverse plane, and in the angular position retracted, which is shown in Figure 1, the cover 24 extends in a plane close to the horizontal plane, so that pass the majority of the light rays emitted by the lamp 12.
- the frame 26 is interposed axially between the frame intermediate 20 and the front transverse surface 22 of the reflector 14. Frame 26 is fixed.
- the projector 10 comprises an actuator 28 which is designed to cause the pivoting of the cover 24 from its concealed position towards its retracted position.
- the actuator 28 here comprises an electromagnet 30 likely to cause axial displacement of a rod control 32, so as to cause the cover to pivot mobile 24.
- the cover 24 is here subjected to the action of a return spring 34, one end of which is trapped in the frame 26, and of which the other end urges the cover 24 towards its position occultation.
- the spring 34 therefore urges the cover 24 towards the rear, in its concealed position, in abutment on a fixed part of the frame 26.
- the spring 34 can be made in the form of a pin, the arms are fixed respectively on the frame 26 and on the cover 24, a loop of the spring 34 surrounding the pivot axis B-B.
- the cover 24 here comprises two transverse surfaces of stop 36, 38 which are provided to come into axial support respectively against two associated scopes 40, 42 which are made on the front transverse face 44 of part of the frame 26.
- the abutment surfaces 36, 38 and the surfaces 40, 42 are arranged here in the vicinity of the transverse ends cover 24 and frame 26 respectively.
- the projector 10 In the rest position of the cover 24, that is to say the concealed position in which it is kept under the action of spring 34, the projector 10 emits a light beam regulatory with a cutoff.
- the upper edge 47 of the cover 24 includes a profile adapted so as to form a shape cut regulatory, for example for the creation of a crossing.
- the cover 24 When the cover 24 is controlled towards its position retracted, by means of the actuator 28, then the cover 24 is mainly found outside the path of light rays emitted by the lamp 12.
- the projector 10 then produces a beam seamless lighting, such as a high beam, or main beam.
- the projector 10 includes at least one locking means 48, 50 intervening between the frame 26 and the cover 24 to retain it in its hidden position.
- the locking means here include elements of magnetic attraction 48, 50.
- the magnetic attraction elements 48, 50 are here permanent magnets which are fixed on the rear transverse face 46 of a part of the frame 26, facing the bearing surfaces 40, 42.
- the frame 26 is made of an alloy ferrous, as well as the cover 24.
- the magnets 48, 50 make it possible to keep the cover 24 glued by its abutment surfaces 36, 38 against the ranges 40, 42.
- the magnets 48, 50 are chosen so that the magnetic attraction force they exert on the cache 24, as well as the return force of spring 34, are less higher than the pivoting force exerted by the actuator 28 on the cover 24, to control it in the retracted position.
- the actuator 28 must fight against the restoring force of the spring 34 as well as against the magnetic attraction force which is exerted by the magnets 48, 50.
- Magnets 48, 50 and their magnetic attraction force can also be adapted according to constraints, in particular vibratory, to which the projector 10 is susceptible to be submissive.
- the movable cover 24 may include surfaces stopper 36, 38 made of ferrous alloy which are mounted on a workpiece made of another material.
- the permanent magnets 48, 50 can be replaced by electromagnets.
- the electromagnets are then controlled by attraction of so as to retain the cover 24 in its concealed position.
- the magnets 48, 50 can be fixed on the cover 24 and exert their magnetic attraction force on spans 40, 42.
- An advantage of the projector 10 according to the invention is that the locking system 48, 50 is easily adaptable to parts produced in series, without requiring modifications complex.
- cover 24 is maintained in the concealed position by the locking means 48, 50, which is preferable to a stowed position which can cause glare for oncoming traffic opposite.
- the locking means 48, 50 here of the type electromagnetic, can be replaced by means of mechanical locking, for example by a device of interlocking, or by a device of "Velcro TM", or by a suction device, these mechanical means intervening between the frame 26 and the cover 24.
- the invention can be adapted on a device of occultation existing, for example on that described in the document FR-A-2,796,449.
- the frame 26 may comprise only one means lock 48 or 50.
