Definitions

  • the present invention is directed to a headlamp for a motor vehicle with a light source arranged in a reflector for emitting light beams in a light exit direction.
  • the headlamp comprises a glare device having a shutter which is movable to a first position and capable of displaying a low beam position to hide at least a portion of the light beams and which is movable to a second position capable of providing a high beam position and in which the diaphragm is at least partially moved out of the light beams, wherein the movement of the diaphragm can be generated with an actuator unit having at least one magnetic coil and a magnetic yoke for forming a magnetic flux circuit.
  • a headlamp for a motor vehicle with a arranged in a reflector light source for emitting light beams in a light exit direction known.
  • the headlamp has a glare device with a shutter which is movable between a first position and a second position.
  • the movement of the diaphragm is caused by an actuator unit having a magnetic coil and a magnetic yoke for forming a magnetic flux circuit.
  • An armature plate which can dip into the magnet coil, is arranged on the diaphragm, wherein the diaphragm and the armature plate can rotate about an axis of rotation which extends transversely to the light exit direction.
  • the glare device has a carrier body to which the axis of rotation is fixedly mounted. Due to the design of the anchor plate as a plunger anchor for immersion in the solenoid results in an arrangement that requires a lot of space. In particular, the required pivot angle is very large, so that the magnetic coil must have a considerable depth, in which the anchor plate dips. A highly dynamic and fast switching between dipped and high beam is thus prevented. Due to the large swivel angle of the aperture and the Separate arrangement of the magnetic coil from the carrier body also increases the necessary space.
  • the invention includes the technical teaching that a hinged armature is provided, which is articulatedly received on at least a part of the magnetic yoke and formed as part of the diaphragm, such that the hinged armature performs a folding movement upon energization of the magnetic coil and generates the movement of the diaphragm.
  • the inventive arrangement of a hinged armature has the advantage that the hinged armature only has to travel a small distance to give away the aperture between the low beam position and the high beam position.
  • the hinged armature is pivotally received on a part of the magnetic yoke, so that it can fold back and forth between two end positions.
  • the folding movement of the hinged armature can be generated by energizing the magnetic coil, wherein the entire panel follows the folding movement of the hinged armature, since this is formed as part of the diaphragm.
  • the diaphragm describes the entire unit which is moved between the high-beam position and the low-beam position.
  • the hinged armature need not be a part of the diaphragm that actually moves into the light rays emitted by the light source. This results in the advantage that the hinged armature can have smaller dimensions than the part of the diaphragm which moves into the light beam. This leverage allows small movements of the hinged armature to cause large movements of the entire panel.
  • the magnetic flux circuit consists at least of the magnetic yoke, which may be bent in an L-shape and the magnetic core, wherein the magnetic yoke and the magnetic core form the stationary components of the magnetic flux circuit.
  • the magnetic flux circuit is closed by the hinged armature, which represents the moving part of the magnetic flux circuit.
  • the actuator unit can be dimensioned considerably smaller in an arrangement with the magnetic flux circuit according to the invention. Consequently, lower activation currents are required and the heat losses are reduced by energizing the actuator unit. Only by the inclusion of a hinged armature in the magnetic flux circuit can such a high Efficiency of the actuator unit can be implemented.
  • the hinged armature closes the magnetic flux circuit, so that it consists at least of the magnetic yoke, the magnetic core and the hinged armature.
  • the hinged armature can be pulled in the simplest case against the magnetic core, so that the hinged armature against the end face of the magnetic core comes to rest when the solenoid is energized.
  • the movement of the shutter corresponds to a rotational movement about a hinge axis, wherein the hinge axis is arranged in the light exit direction.
  • the rotational movement of the diaphragm takes place about a hinge axis, wherein the diaphragm has a diaphragm arm, which folds into a part of the light beam when the diaphragm is pivoted into the Abbleriumt ein.
  • the diaphragm arm has an elongated extension and, together with a carrier body of the diaphragm device, forms the part of the diaphragm device located in the light beams.
  • the hinge axis can be arranged either transversely to the light exit direction or in the light exit direction.
  • the hinge axis in the light exit direction results for the hinged armature due to the inventive coupling of the hinged armature with the shutter shorter ways that the hinged armature between the Abbleriumt ein and the high beam position must cover.
  • the inventive arrangement of the hinged armature therefore has a hinge axis which is parallel to the light exit direction.
  • the actuator can be arranged next to the carrier body, wherein the actuator unit can be arranged with the hinged armature on a first, front side of the carrier body, wherein the diaphragm arm is designed in the manner of a rod-shaped sheet extending in a plane extending on the the actuator unit opposite side of the carrier body extends.
  • the articulated receptacle of the hinged armature is formed on the magnetic yoke by a hinge assembly through which the magnetic flux between the magnetic yoke and the hinged armature passes.
  • the magnetic flux circuit passes through both the magnetic yoke and the hinged armature.
  • the joint arrangement therefore preferably comprises components which are magnetically conductive.
  • the hinge assembly can be formed directly by the hinged armature and the magnetic yoke, so that touch the hinged armature and the magnetic yoke in the hinge axis. This results in a magnetic coupling, and the conclusion of the magnetic flux circuit is guaranteed despite the hinge assembly between the hinged armature and the magnetic yoke.
  • the diaphragm can be formed at least from the diaphragm arm and from the hinged armature, wherein the hinged armature is designed plate-shaped and extending in a plane perpendicular to the plane of extension of the diaphragm arm of the diaphragm.
  • the extension plane of the diaphragm arm is perpendicular in the light exit direction, wherein the hinged armature has an extension plane, which is formed on the one hand by the light exit direction and on the other hand by the horizontal of the headlamp in the installed state, the hinged armature can slightly leave the horizontal between the Abbleriumtwolf and the high beam position.
  • the diaphragm arm extends in the vertical direction of the headlamp in order to partially hide the light emerging approximately horizontally from the headlamp.
  • the diaphragm has a balancing mass, which is designed plate-shaped and extending in a plane perpendicular to the hinged armature and perpendicular to the shutter arm. Consequently, the plate-shaped balancing mass, the diaphragm arm and the hinged armature respectively form mutually perpendicular planes.
  • the balancing mass can also assume any further geometric shape and does not have to be designed plate-shaped.
  • the balancing mass serves to balance the mass of the visor arm and the hinged armature, so that the center of gravity of the diaphragm lies in the hinge axis in order to make the glare device insensitive to external impacts and accelerations.
  • the balancing mass, the diaphragm arm and the hinged armature can be made in one piece, wherein at least two of the three components of the diaphragm can be made in one piece, so that the third component is connected via a connection method with the other two components or all three components
  • the panel are designed as individual parts and connected to each other.
  • the hinged armature can be made of a material of high magnetic permeability, whereas the permeability of the visor arm and / or the balancing mass must not be guaranteed and they are made of a lightweight material.

The force application of the hinged armature by the clip spring takes place on the side of the hinge axis, which corresponds to the opposite side on which the hinged armature interacts with the magnetic core.
  • the hinged armature If the hinged armature is biased in the rear area behind the hinge axis in the direction of the magnetic yoke, the hinged armature remains in the low beam position. If the solenoid is energized, the hinged armature is pulled towards the magnetic core, wherein the movement takes place against the bias of the spring element. Consequently, a monostable arrangement of the hinged armature so that it is transferred only when the solenoid is energized from the low beam position to the high beam position and remains in the low beam position when not energized the solenoid.

  • the tension spring may be received in the hinged armature in a punched or notched retaining mandrel, wherein the retaining mandrel is also disposed on the side of the hinged armature relative to the hinge axis, which corresponds to the opposite side of the hinged armature in the interaction region of the magnetic core.
  • a further improvement of the magnetic force acting on the hinged armature is achieved in that the magnetic core has a plate-shaped extension with a cylindrical projection, which extends in the direction of the hinged armature from the magnetic coil out, wherein the hinged armature has a recess into which extends the approach.
  • the recess in the hinged armature encloses the cylindrical projection of the magnetic core at least partially, and preferably also the portion of a semicircle.

When the magnetic coil is energized, a magnetic flux can be amplified by the plate-shaped extension, and the hinged armature is attracted to the plate-shaped extension.
  • a further enhancement of the magnetic force on the hinged armature is achieved by the arrangement of the cylindrical projection which extends into the recess within the hinged armature. Since the recess in the hinged armature at least partially surrounds the cylindrical projection and only forms a small gap with the cylindrical projection, the magnetic flux between the hinged armature and the magnet core is further increased via the small gap.
  • the hinge arrangement between the magnetic yoke and the hinged armature may have an arcuate recess in the connecting region to the magnetic yoke, in which a rolling surface of the hinged armature is accommodated.
  • the rolling surface rolls during movement of the hinged armature along the arcuate recess, such that the existing gap between the cylindrical projection of the magnetic core and the recess of the hinged armature remains essentially unchanged over the movement of the hinged armature. It follows that the magnetic force acting on the hinged armature already assumes large values when the hinged armature is still in the low beam position.
  • the hinge assembly does not form a pure hinge, but the rotational movement of the hinged armature is superimposed by a rolling movement of the rolling surface of the hinged armature within the arcuate recess.
  • the actual pivot point of the hinged armature relative to the magnetic yoke is therefore not located in the contact point between the rolling surface and the arcuate recess, but may be located far from the contact point.
  • the arch shape of the recess is designed such that the gap between the neck of the magnetic core and the recess of the hinged armature over the entire path of movement the hinged armature remains substantially the same.
  • the gap may have a value of 0.05 mm to 0.3 mm, preferably a value of 0.1 mm to 0.25 mm, and particularly preferably a value of 0.18 mm.
  • Another embodiment of the glare device may include a counter-anchor located in the magnetic flux of the actuator unit.
  • the counter-anchor can be placed on the hinged armature end of the magnetic core and has a force flow edge, which extends parallel to a counter-edge formed on the hinged armature.
