Technical Field

The invention relates to an adjustment system for pivoting at least one optically relevant component of a vehicle headlight about a first axis and a second axis. The invention further relates to a lighting device for a motor vehicle headlight, comprising an adjustment system according to the invention. The invention further relates to a vehicle headlamp, in particular a motor vehicle headlamp, having an adjustment system according to the invention and/or a lighting device according to the invention.

Background

Adjustment systems are known from the prior art and are usually used in vehicle headlight applications to adjust the vertical deflection (for example, the adjustment of the illumination distance) or the horizontal deflection (basic adjustment or, for example, the cornering light) of the light distribution.

Such an adjustment system is known, for example, from AT 513918B 1. The adjustment system should on the one hand allow a reliable adjustment of the optically relevant components and on the other hand minimize the space requirement of such an adjustment system in order to limit the design of the vehicle headlight as little as possible.

Adjustment systems of this type have mostly had an adjustment triangle with a fastening point and two operating points, wherein each axis is formed by a connection formed by the fastening point and the operating point, and a pivoting movement is produced by a displacement of the operating point. Such an adjustment system has a certain space requirement due to the construction of the oscillating triangular structure.

Disclosure of Invention

It is therefore an object of the present invention to provide a regulating system which has a reduced space requirement. This object is achieved by means of a control system of the type mentioned at the outset, which according to the invention has the following features: a first holding element for holding an optical-related member; a second holding element for displaceably holding the first holding element at the second holding element; a carrying frame for displaceably holding the second holding element at the carrying frame; and a first adjusting device acting on the first holding element for displacing the first holding element relative to the second holding element; and a second adjusting device acting on the second holding element for displacing the second holding element relative to the carrier frame, wherein the first holding element and the second holding element have a first set of mutually engaging guide means by means of which the displacement of the first holding element relative to the second holding element is guided along an arc of a circle around a first axis, and wherein the second holding element and the carrier frame have a second set of mutually engaging guide means by means of which the displacement of the second holding element relative to the carrier frame is guided along an arc of a circle around a second axis, wherein the first axis and the second axis are oriented normal to each other.

By dispensing with the conventional arrangement with an adjusting arm and a bearing point (which is configured as an adjusting triangle) and instead of using a holding element displaceable along a circular arc according to the invention, the structural volume of the adjusting system can be significantly reduced. The adjustment system according to the invention allows adjustment along a truncated sphere arc (sometimes called a spherical cap arc).

The circular arc is selected such that the associated axis of rotation is located in the apex or (measured in the main emission direction) at the apex or outside the optically relevant component in a region arranged behind the optically relevant component in the light emission direction.

Especially light barriers, light sources, especially LED and/or laser light sources, reflectors, lenses and/or the entire light module or assembly etc. are considered as optically relevant components. Thus, single or multiple ones of the mentioned components can constitute an optical-related component which can be adjusted by means of the adjustment system.

In particular, it can be provided that the first axis is oriented horizontally and the second axis is oriented vertically. The description of the orientation here relates to the installed state of the adjustment system. Via the horizontal axis, the illumination distance of the vehicle headlight can be adjusted, for example. The light image of the vehicle headlight can be pivoted laterally by means of the vertical axis.

Alternatively, it can be provided that the first axis is oriented vertically and the second axis is oriented horizontally.

In particular, it can be provided that the optically relevant component comprises a mapping optical element. A mapping optical element is understood within the scope of the present disclosure as each optical element by means of which the light distribution is finally shaped. In this case, for example, a reflector can be used. In most cases, however, lenses, in particular projection lenses, are provided for the final light shaping.

The adjustment system can expediently be designed such that the mapping optical element has a main emission direction which is oriented normal to the first axis and the second axis in the intermediate position. For this purpose, it can be provided that the mapping optical element has a main emission direction along the optical axis, wherein the mapping optical element can be pivoted about the first axis and the second axis in such a way that the optical axis can be oriented normal to the first axis and the second axis.

In particular, it can be provided that the mapping optical element is a lens, in particular a projection lens.

Furthermore, it can be provided that the first axis and the second axis intersect one another. It is thereby possible for the optically relevant component to be pivoted only about a single point (i.e. the intersection of the two axes).

In particular, it can be provided that the mapping optical element, in particular the projection lens, has an apex, wherein the first axis and the second axis intersect one another in the region of the apex. This results in particular advantages: the wobbling motion is only performed around the apex of the mapping optical element. The pivoting movement is caused in this case to change only the orientation of the apex, but not the position of the apex. This feature is particularly advantageous since the apex of the mapping optical element in the vehicle headlight housing is typically the component which projects furthest in the direction of the cover disk, since the apex remains positionally stable during the pivoting movement and therefore the space requirement of the mapping optical element is minimal despite the possibility of pivoting. As already mentioned, the apex lies at the top of the mapping optical element in the direction of its optical axis, wherein the expression "in the region" means that the intention is to enable the intersection of the axes to coincide substantially with the apex, but deviations of a few millimeters can occur.

Advantageously, it can be provided that the first set of guide means has at least one receiving section in the shape of a circular arc, in which at least one corresponding guide projection, likewise associated with the first set of guide means, is received, wherein the receiving section is associated with the second holding element and the guide projection is associated with the first holding element, or vice versa. This enables guidance along a circular arc to be achieved in an efficient manner.

In this connection, it is to be noted that all the mentioned circular arcs each form a section of the circular track, wherein the circular arcs can extend over an angle of, for example, between 2 ° and 45 °, in particular between 5 ° and 20 °, particularly preferably between 7 ° and 15 °.

Furthermore, it can be provided that a rotary shaft is mounted on the second holding element, said rotary shaft being oriented parallel to the first axis and having at least one toothed (sometimes referred to as meshing) section, wherein the first holding element has a corresponding toothed section by means of which the first holding element is supported on the second holding element, wherein the toothed section of the first holding element engages with the toothed section in such a way that a pivoting movement of the first holding element about the first axis brings about a rotary movement of the rotary shaft. The rotary shaft thus supports the first holding element and prevents play in the movement of the associated pivoting device.

Advantageously, it can be provided that the second set of guide means has at least one receiving section in the shape of a circular arc, in which at least one corresponding guide projection, likewise associated with the second set of guide means, is received, wherein the receiving section is associated with the carrier frame and the guide projection is associated with the second holding element, or vice versa. This enables guidance along a circular arc to be achieved in an efficient manner.

Furthermore, it can be provided that a rotary shaft is mounted on the carrier frame, said rotary shaft being oriented parallel to the second axis and having at least one toothed section, wherein the second holding element has a corresponding toothed section, by means of which the second holding element is supported on the carrier frame, wherein the toothed section of the second holding element engages with the toothed section in such a way that a pivoting movement of the second holding element about the second axis causes a rotary movement of the rotary shaft. The rotary shaft thus supports the second holding element and prevents play in the movement of the associated pivoting device.

Held displaceably for pivoting about a horizontal axis in a guide track, wherein the guide track is configured as a circular arc, the center point of which forms a rotational axis, wherein the rotational axis is oriented horizontally and intersects the apex of the projection lens.

In particular, it can be provided that the first adjusting device is provided for a fixed connection in a fixed position to the vehicle headlight housing, wherein the first adjusting device has a pivot arm which can be pivoted by means of the first adjusting device about an axis oriented parallel to the first axis, wherein the pivot arm has a coupling section which is provided for engaging into a corresponding coupling section of the first holding element for pivoting the first holding element about the first axis, wherein the respective coupling section is provided for the force-fitting transmission of a pivoting movement of the pivot arm to the first holding element, wherein the respective coupling section can be displaced relative to one another. The coupling section can be configured to be displaceable in the direction of and transversely to the first axis.

Furthermore, it can be provided that the second adjusting device is provided for a fixed connection in a fixed position to the vehicle headlight housing, wherein the second adjusting device has a displacement arm which can be displaced in the first axial direction by means of the second adjusting device, wherein the displacement arm has a coupling section which is provided for engaging into a corresponding coupling section of the second holding element for pivoting the second holding element about the second axis, wherein each coupling section is provided for the force-fitting transmission of a displacement movement of the displacement arm to the second holding element.

The adjustment of the optically relevant component by means of the first adjustment device takes place independently of the adjustment by means of the second adjustment device. That is, the adjustment devices function independently of each other. The two adjusting devices should not influence each other, and in the case of a vertical adjustment, for example, a horizontal deviation can be maximum, for example, 0.7 °.

The invention further relates to a lighting device for a motor vehicle headlight, comprising an adjustment system according to the invention and an optically relevant component. Furthermore, the lighting device can comprise at least one light source or a plurality of light sources, wherein, for example, LED light sources, halogen light sources and/or laser light sources can be provided here.

The invention further relates to a vehicle headlamp, in particular a motor vehicle headlamp, having an adjustment system according to the invention or a lighting device according to the invention. The invention further relates to a vehicle, in particular a motor vehicle, having at least one vehicle headlamp according to the invention.

The adjustment system according to the invention can be used for adjusting a large number of different light distributions and light systems. Such adjustment systems can be used, for example, for cornering lights, low beams, high beams, laser scanners, LED matrix headlamps, etc.

Detailed Description

In the following drawings, like reference numerals denote like features unless otherwise specified.

Fig. 1 and 2 show different perspective views of a first embodiment of an adjustment system 1 according to the invention for pivoting at least one optically relevant component 2 of a vehicle headlamp about a first axis y and a second axis z.

The adjustment system 1 includes: a first holding element 3 for holding the optical-related component 2; a second holding element 4 for displaceably holding the first holding element 3 at the second holding element 4; a carrying frame 5 for displaceably holding the second holding element 4 at the carrying frame 5; and a first adjusting device 6 acting on the first holding element 3 for displacing the first holding element 3 relative to the second holding element 4. Furthermore, the adjustment system 1 comprises a second adjustment device 7 acting at the second holding element 4 for displacing the second holding element 4 relative to the carrying frame 5, wherein the first holding element 3 and the second holding element 4 have a first set of guiding means 3a and 4a engaging each other. The first set of guiding means 3a,4a guides the displacement of the first holding element 3 with respect to the second holding element 4 along an arc KBy around the first axis y (see fig. 4). In the present example, the first axis is oriented horizontally and normally relative to a main travel direction x of the vehicle, wherein the main travel direction x and the first axis y run out of a plane, which is oriented normal to a vertically oriented second axis z. Alternatively, the first axis y can likewise be oriented vertically, while the second axis z can be oriented horizontally.

The second holding element 4 and the carrying frame 5 have a mutually engaging second set of guiding means 4b and 5a, by means of which second set of guiding means 4b,5a the displacement of the second holding element 4 relative to the carrying frame 5 along an arc KBz around the second axis z is determined (see fig. 5). Here, the first axis y and the second axis z are oriented normal to each other. The arcs are designed such that the respective axis coincides with the center point of the respective arc.

The first group of guide means 3a,4a has at least one receiving section 4a in the shape of a circular arc, which is delimited by a retaining lug (sometimes referred to as a retaining nose) 4a', in such a way that the guide means 3a received in the receiving section 4a (which is configured, for example, in the form of a projection) can, in the assembled state, only be pivoted about the axis y and is prevented as far as possible from being displaced in the other direction. For this purpose, in the present exemplary embodiment, four retaining projections 4a' are provided, which are formed on opposite sides of the second retaining means 4. Fig. 1 shows a retaining projection 4a 'on the right side of the adjustment system 1, while fig. 2 shows a retaining projection 4a' on the left side of the adjustment system 1 (seen from the front). Furthermore, it can be seen in fig. 1 that a rotary shaft 4c is mounted on the second holding element 4, said rotary shaft being oriented parallel to the first axis y and having at least one toothed section 4c ', wherein the first holding element 3 has a corresponding toothed section 3c', by means of which the first holding element 3 is supported on the second holding element 4. The toothed section 3c 'of the first holding element 3 engages with the toothed section 4c' in such a way that pivoting of the first holding element 3 about the first axis y causes a rotational movement of the rotational shaft 4 c. The pivot axis 4c thus minimizes the play of the movement of the first holding element 3 and ensures a particularly reliable guidance.

A second set of guiding means can also be provided similar to the first set. The second group of guide means 4b and 5a has at least one receiving section 5a in the shape of a circular arc, in which at least one corresponding guide projection 4b, which is likewise associated with the second group of guide means 4b and 5a, is received. The receiving section 5a is associated with the carrying frame 5, while the guiding projection 4b is associated with the second holding element 4 (or vice versa). A holding projection 5a' is formed on the support frame 5. Furthermore, a rotary shaft 5c is mounted on the support frame 5, said rotary shaft being oriented parallel to the second axis z and having at least one toothed section 5c', the second holding element 4 having a corresponding toothed section 4c ″ by means of which the second holding element 4 is supported on the support frame 5. The toothing 4c ″ of the second holding element 4 engages with the toothed section 5c' in such a way that a pivoting movement of the second holding element 4 about the second axis z causes a rotational movement of the rotational shaft 5 c. Similarly to the rotation axis 4c, the rotation axis 5c gives rise to: the play of the displacement mechanism is minimized.

In the present exemplary embodiment, it is provided that the optically relevant component 2 comprises a mapping optical element, i.e. in the form of a projection lens. The projection lens has a main radial direction along the optical axis, wherein the mapping optical element can be pivoted about the first axis y and the second axis z in such a way that the optical axis can be oriented normal to the first axis y and the second axis z. In other words, this means that the arcs 4a and 5a or the entire adjusting mechanism are configured accordingly. As can be seen in fig. 1, the projection lens 2 has an apex P, wherein the first axis y and the second axis z intersect one another in the region of the apex P.

The first adjusting device 6 is provided for a fixed connection in a fixed position to the vehicle headlight housing, wherein the first adjusting device 6 has a pivot arm 6a which can be pivoted by means of the first adjusting device 6 about an axis oriented parallel to the first axis y, wherein the pivot arm 6a has a coupling section 6d 'which is provided for engaging into a corresponding coupling section 3d' of the first holding element 3 for pivoting the first holding element 3 about the first axis y. The coupling sections 6d 'and 3d' are provided for the force-fitting transmission of the oscillating movement of the oscillating arm onto the first holding element 3, wherein the coupling sections 6d 'and 3d' are displaceable relative to one another.

The interaction of the coupling sections 6d 'and 3d' is shown in detail in fig. 8a and 8 b. In these figures, it can be seen that the coupling section 6d 'is designed as a ball head which is received in a correspondingly shaped recess 3d', wherein the ball head can be displaced in the recess in such a way that, on the one hand, the pivoting movement of the arm 6a is transmitted in a force-fitting manner to the first holding element 3 and, on the other hand, a movement path which is offset by the different pivot axes of the pivot arm 6a and the first holding element 3 can be compensated. Likewise, a displacement in the direction of the y axis is possible, which displacement is caused by the pivoting of the second holding element 4 about the second axis z, since the first holding element 3 moves together with the second holding element 4.

In fig. 1 and 6, it can be seen that the second adjusting device 7 of the adjusting system 1 has a displacement arm 7a which can be displaced in the direction of the first axis y by means of the second adjusting device 7, wherein the displacement arm 7a has a coupling section 7d 'which is provided for engaging into a corresponding coupling section 4d' of the second holding element 4 for pivoting the second holding element 4 about the second axis z, wherein the coupling sections 4d 'and 7d' are provided for the force-fitting transmission of the displacement movement of the displacement arm 7a to the second holding element 4. In the present embodiment, the coupling section 7d 'is embodied as a ball head which engages into the corresponding cylinder receiving opening 4d', wherein the longitudinal axis of the cylinder receiving opening is oriented normal to the first axis y. The longitudinal displacement of the displacement arm 7a can be achieved in the present exemplary embodiment by a rotation about its longitudinal axis, since the displacement arm 7a has a threaded section 7e which acts on a threaded section 5e of the stationary support frame 5 (see fig. 6). The design of the adjusting devices 6 and 7 is not discussed in detail below, since such a design is sufficiently known from the prior art and in the present case only has to be provided for displacing the displacement arm 7a or swinging the swing arm 6 a.

Fig. 3 to 5 show different views of the adjustment system 1, wherein only separate reference numerals are drawn for greater clarity. As can be seen in FIG. 4, an exemplary vertical adjustment range includes an angle of +/-7.5 from a zero position. As can be seen in FIG. 5, an exemplary lateral adjustment range is an angle of +/-3.5 from the zero position.

Fig. 7 shows a perspective detail of the already described horizontal pivoting mechanism of the adjustment system 1. Fig. 9a to 9g show some steps of the assembly of the adjustment system according to fig. 1 to 8b, wherein reference numerals are not shown in the figures for greater clarity.

Fig. 10 shows an alternative embodiment of the adjustment system 1 according to the invention. In this embodiment, the adjusting devices 6 and 7 are configured differently, i.e. as servomotors, the rotational axes of which act directly on the rotational shafts 4c or 5 c.

In principle, the invention can be used for a large number of different light functions. By way of example, bend light, low beam, high beam, laser scanner, LED matrix light, etc. are listed in this connection.

Given this teaching, one skilled in the art can, without inventive effort, derive other, non-illustrated embodiments of the present invention. The invention is therefore not limited to the embodiments shown. Aspects of the invention or embodiments can also be considered and combined with each other. What is important is the idea on which the invention is based, which can be implemented in a wide variety of ways and nevertheless maintained as such by a person skilled in the art with the understanding of the present description.
