Embodiment Construction

[0041] figure 1 A perspective view of the adjusting device 11 according to the invention is shown. The adjusting device 11 comprises a servomotor 1 which is accommodated in a housing 2 , wherein an adjusting element 3 protrudes at least partially from the housing 2 . An adjusting device 11 is used to adjust optically important elements of a motor vehicle headlight (not shown in the figures), wherein the adjusting device 11 has an actuator 7 which is moved along a displacement axis x by means of a servomotor 1 (see for example image 3 ), a transmission part 8 connected to the actuator 7 for movement along the movement axis x and rotatably supported around the movement axis x (for example see image 3 ), the adjustment part 3 and the rotating part 6 for the rotation transmission part 8, which is rotatably supported around the movement axis x (see for example figure 2 and 3 ). Adjustment part 3 and transfer part 8 utilize connection 8b and 3b (see for example image 3 ) ar...

Abstract

The present invention provides an adjustment device (11) for a motor vehicle headlamp. The adjustment device comprises an actuator (7), which moves along a movable axis (x) by utilizing a servo motor (1); a transmitting part (8), which is connected to the actuator (7), movably adjusts along the movable axis (x) and rotates and supports around the mvable axis (x); an adjustment part (3) which mechanically engages with the transmitting part (8) by utilizing connections (8b, 3b), wherein, the adjustment part (3) is embedded into an important optical element and a rotation part (6), and the rotation part (6) is used for adjusting the rotation of the transmitting part (8) and rotationally supporting around the movable axis (x). The connections (8b, 3b) of the transmitting part (8) and the adjustment part (3) is configured in a mode that the rotational motion of the transmitting part (8) is converted into the movable motion of the adjustment part (3) along the movable axis (x).

Description

technical field [0001] The invention relates to an adjustment device for adjusting an optically important element of a motor vehicle headlight, which has an actuator which is moved along a movement axis by means of a servo motor, and which is connected to the actuator for movement and adjustment along the movement axis and which can surround A transmission element mounted in rotation about the axis of movement, an adjustment element mechanically engaged with the transmission element by means of a connection, and a rotating element mounted in rotation about the axis of movement for adjusting the rotation of the transmission element, wherein the adjustment element is arranged so as to engage in an optically important on the components. Background technique [0002] Adjustment devices for adjusting optically important elements of the headlight, such as light sources, reflectors and / or lenses, allow the light pattern produced by the headlight to be adapted to given requirements....
