Problems solved by technology

However, the cut-off mechanism intended to achieve this ADB function requires expensive technology, such as actuation by stepper motors, position sensors, etc.
[0007] In particular, actuator motors as described above are usually relatively expensive

Embodiment Construction

[0033] refer to figure 1 , the motor vehicle headlamp 1 configured to generate a light beam (schematically indicated by arrow F) can be seen in perspective. In general, the headlamp 1 generally comprises a substantially rectangular frame, as described below, arranged substantially parallel to a plane P. As shown in FIG. The plane P is perpendicular to the optical axis X of the light beam F.

[0034] The frame 2 comprises an opening 3, preferably cut out at the center of the frame, to allow the passage of light beams, as Figure 2 to Figure 6 shown.

[0035] Behind this frame, in an invisible manner, a light source generating a beam of light and a reflector directing this beam towards the front and towards a lens mounted towards the front of the headlamp 1 are arranged.

[0036] In addition to the lens, the headlamp 1 also includes conventional means for controlling the shape of the light beam in order to adapt it to the situation in which the vehicle is driving.

Abstract

Disclosed is a headlamp comprising: a frame (2) defining a light beam passage opening (3), a fixed protective cover (5) and a cut-off mechanism (4), the cut-off structure including a movable Assembly and at least one actuating motor, said movable assembly (8) comprising a cut-off lever (11) provided with a cut-off piece (12), said cut-off lever (11) being able to be moved by the actuating motor in at least one closed position (C1 ) and a retracted position, in at least one closed position, the cut-off piece (12) partially closes the opening (3) in the region of the fixed protective cover (5), in the retracted position, the cut-off piece (12) releasing the opening (3), the protective cover (5) comprising at least one closing plate (13), the closing plate (13) and the cut-off piece (12) are designed to be joined together so that in The closed position (C1) forms a closed surface.

Description

technical field [0001] The field of the invention is that of headlamps, more particularly of headlamps for motor vehicles. Background technique [0002] Motor vehicle headlamps typically include a light source that projects light onto a reflector. The light is then reflected off the lens to be reversed and returned to the exterior of the vehicle in the form of a beam. The headlamp also includes a cut-off mechanism for blocking or not blocking a portion of the reflected beam, and means for controlling the shape of the beam to adapt said beam to driving conditions. [0003] The use of cut-off mechanisms comprising a rotating cut-off lever is known. The cut-off bar is electrically actuated to move on command between at least two angular positions in which it blocks the light beam to a greater or lesser extent. In the case of so-called dual-function headlamps, these two positions are a first angular position and a second angular position in which the cut-off bar blocks a part...
