Description

Simplified cover kinematics for a head-up display of a motor vehicle

The invention relates to an adjusting device for adjusting a position of a

Combination disc of a head-up display for a motor vehicle, comprising a movable Kombinierscheibeneinrichtung with the Kombinierscheibe, wherein the Kombinierscheibe is designed for overlaying optical information, with a drive means which is arranged on a support means of the adjusting device, and by means of which the Kombinierscheibeneinrichtung relative to the support means is movable and can be brought into an adjustment position and in a position of use, and with a movable cover, which in a stowed position associated with the cover a shaft of the adjusting device, in which the

Kombinierscheibeneinrichtung is arranged in the stowage position, covers and releases the shaft in a release position associated with the use position.

Head-up displays, so-called head-up displays, which are designed as a combination mirror or combination disc head-up display, so-called combiner head-up displays, usually have a complicated construction, by means of which a combination disc of the headset top display can be moved in and out of a housing. The housing is usually adapted in each case to the space available in a vehicle to be equipped in each case with the combiner head-up display. This space and thus also the shape and size of the housing varies from vehicle to vehicle. Accordingly, an adjusting device for the combiner, a so-called kinematics of the head-up display for each housing must be readjusted. This is very expensive, not least because the

corresponding Versteilvorrichtungen or kinematics each having a plurality of different components.

From US 355 28 28 A, a combiner head-up display is known, in which an exchangeable combination mirror can be brought into different positions via a simple toggle technology as kinematics.

US Pat. No. 9,063,329 B2 describes a device for covering a combination mirror and a display device. The display can be folded away. The combination mirror can be moved here via a multi-part sliding cover between a use position and a stowed position.

The invention has for its object to be able to realize or realize a simplified head-up display with a reduced number of components, which

especially universally usable.

This object is solved by the subject matter of the independent claim. Advantageous embodiments will become apparent from the dependent claims, the description and the figures.

The invention relates to an adjusting device for adjusting a position of a

Combination disc of a head-up display for a motor vehicle. The adjusting device is therefore for a head-up display, a so-called head-up display, one

Motor vehicle determined. The adjusting device has a movable

Combination disc device with the Kombinierscheibe, wherein the Kombinierscheibe is designed for overlaying an optical information. The combiner can also be referred to as a combination mirror. Through the combination disc

or the so-called combiner, an information of an environment can be superimposed or combined with an information generated artificially, for example by a display device. The combiner may comprise a specular translucent disk, also known as a semi-transparent mirror.

The adjusting device also has a drive device which on a

Carrier device of the adjusting device is arranged. By means of the drive means the Kombinierscheibeneinrichtung is movable relative to the support means. By the drive means the Kombinierscheibeneinrichtung in a stowed position and in a different position of the stowage position can be brought,

or between these back and forth movable. The drive device can also have a control device which controls the drive device according to a desired position of the Kombinierscheibe. The

Kombinierscheibeneinrichtung can also in several different

Use positions can be brought, which may differ from each other for example by a respective different angle of the Kombinierscheibe relative to the support means. About such an angular adjustment, which will be described below, for example, a head-up display with a such adjusting device better adapted to different sizes by a viewer.

Moreover, the adjusting device has a movable covering device, which is associated with one of the stowing positions of the combining pane device

Covering a shaft of the adjusting device, in which the

Kombinierscheibeneinrichtung is arranged in the stowage position, covers or closes and releases the shaft in a release position associated with the use of the Kombinierscheibeneinrichtung, so that the

Kombinierscheibeneinrichtung in the position of use can at least partially protrude from the shaft. The covering device is thus designed to be movable between the covering position and the release position.

It is important here that the drive device has at least two gears with mutually parallel axes of rotation, wherein the axes of rotation in the stowed position of the Kombinierscheibeneinrichtung or over a majority of

Positions of the Kombinierscheibeneinrichtung along the movement between the stowed position and the use position transverse to a main plane of the Kombinierscheibeneinrichtung or Kombinierscheibe stand. Thus, the gears can be arranged coplanar to the main extension plane of the Kombinierscheibeneinrichtung, ie to the main extension plane of the Kombinerscheibeneinrichtung when it is in the stowed position or if they are in one

Orientation in which it is located over a majority of the positions of the Kombinierscheibeneinrichtung along the movement between the stowed position and the use position.

In addition, the toothed wheels each have on a side surface, preferably a rear or rear side surface opposite the front side surface, ie in particular a rear side surface oriented oppositely to the front side surface, a contour ring on which the covering device at least rotates the gears and thus moves of the

Combination disc means between the stowage position and the use position is applied, so that by an axial contour of the contour ring, the movement of the

Covering device between the covering position and the release position is controllable. The terms of the front and rear side surface are thus to be understood as declaratory in the sense of a first and a second side surface. The contour ring is in particular designed to transmit a force to the cover and the Cover device so that to move from the covering position in the release division and to keep the cover in the release division. This can, for example, by a pressure which, via the contour ring against a spring on the

Coverage acts, implemented. In the same way, of course, the contoured ring can conversely be designed to move the covering device out of the release division and to hold it in the covering position. The contoured ring may be designed as an outer peripheral edge of the respective gear and axially projecting wall. This wall can have a different height in the axial direction and thus determine the axial contour of the contour ring. The covering device can also rest against the contoured ring not only when the gears rotate, but also, for example, when the gearwheels are stationary, specifically in the covering position and / or the release division. In particular, the cover can also rest continuously, ie, regardless of the position of the gears on the contour ring.

This has the advantage that over the respective design of the contour ring

Movement pattern for the covering can be freely and flexibly specified. Moreover, no additional parts are needed here for the control of the movement of the cover, but the movement can be realized via the gears, which is also implemented by moving the Kombinierscheibeneinrichtung between stowage and use position. Thus, a movement of the covering is automatically connected to the movement of the

Adjustment device or the Kombinierscheibeneinrichtung coupled so that no complex electronic control or synchronization is required. Also, particularly large gears can be used in the drive device. Since these are arranged substantially parallel to the Kombinierscheibeneinrichtung, this is also very little space required. Due to the large gears, the drive device is also particularly quiet, since correspondingly low speeds can be selected for a drive motor and fewer resonances occur. In particular, the lateral space requirement is reduced because the gears and thus a large part of the drive in front of or behind the

Combination disc device can be arranged, and so laterally in the

Main extension plane of Kombinierscheibeneinrichtung no further space is required. The arrangement of the driver cam is independent of the arrangement and / or design of the contour ring, so that for the cover and the

Kombinierscheibeneinrichtung independently a movement pattern or a movement can be specified. At the same time so only one drive motor is required, so that the number of components and the space required is further reduced. In an advantageous embodiment, it is provided that the axes of rotation are at an angle between 0 ° and 20 ° to the Haupterstre ckungsebene, in particular at an angle between 0 ° and 10 °. In a particularly preferred embodiment, the angle can also be between 0 ° and 5 ° or between 0 ° and 1 °. In particular, the angle between the axes of rotation and the main plane of the Kombinierscheibeneinrichtung within the known measurement tolerances may also be 0 °. This results in a coplanar arrangement of the gears with the

Combination disc device or the Kombinierscheibe achieved.

This has the advantage that very little space is needed. Moreover, such a distance between the gears and the Kombinierscheibeneinrichtung can be minimized so that a mechanical interaction, as specified below, and which serves to move the Kombinierscheibeneinrichtung between the stowed position and the position of use, can be accomplished more easily.

In a further advantageous embodiment, it is provided that the contour rings in the axial direction of the respective gear have a respective trough and the

Covering device engages in the covering position in the respective trough and

engages in particular in the trough on the contour ring. The trough can also be referred to as a groove or recess or cutout in the above-described wall or recess in the contour of the contour ring or executed.

This has the advantage that over the well, especially in combination with a, apart from the trough, even contour, ie a wall of uniform height, in a particularly simple manner a movement of the cover in a depth direction, which parallel to the axes of rotation of the gears runs, can be implemented. Thus, for example, when the gears rotate, the cover device can be quickly removed from a movement path of the combination mirror device which runs in the vertical direction.

In a particularly advantageous embodiment, it is provided that the

Covering device has a cover plate for covering the shaft, as well as two tilting arms, by means of which the covering device between the covering position and

Tilting position is stored tilted at each pivot point. Through the two pivot points can run a rotation axis of the cover. In each case, a finger or pin is arranged on the tilting arms, which in the rotation of abuts the contours and engages in particular in the covering in the trough. The finger thus moves in the rotation of the gear from a contour of the contour ring and thus controls the movement of the cover.

This has the advantage that a desired movement of the covering device or the cover plate can be realized in a simple manner via the described geometry via a variation of the length of the tilting arms, as well as a variation of the position of the pivot points and the fingers on the tilting arms.

In a particularly advantageous embodiment, it is provided that the fingers are arranged on the respective tilting arm between the cover plate and the respective pivot point. In particular, the pivot point can be arranged on a respective, preferably the cover plate, remote end region of the tilting arms.

The said embodiment has proven to be particularly advantageous in the head-up display area dimensions, movement speeds and forces to move quickly with minimal effort, the cover quickly from the covering position in the release position and keep them there.

In a further advantageous embodiment, it is provided that the fingers are oriented with their respective main extension direction radially to the respective associated gear. The fingers can thus stand at a corresponding point of contact with the contour ring at a right angle to the contour ring. In particular, a respective main extension direction of the fingers is also oriented essentially at right angles to the main extension direction of the associated tilting arm.

This has the advantage that the finger can be made very short, which reduces mechanical stress and space requirements. Thus, the cover is also mechanically very stable.

In a particularly advantageous embodiment, it is provided that the toothed wheels each have at least one eccentrically arranged on a front side surface

Have cam-cam, which in a Querführungsnut the

Combination disc means engages and which is designed for moving or moving the Kombinierscheibeneinrichtung a force on the

To transfer Kombinierscheibeneinrichtung. Under the front side surface of the Gears here is first to understand a side face of the gears, which may be the other side face of the gears with respect to a rear side surface of the gears on which the contour rings are arranged. Under front and rear side surface of a gear so in particular two oppositely oriented side surfaces of the gear can be understood, so that driver cam and fingers are arranged on different side surfaces. The driver cams are each eccentric, that is arranged outside of a center or pivot point of the gears on the respective gear. As a result, the rotational movement of the toothed wheels can be converted into a rectilinear movement of the combination disc device by the cam cams. Upon rotation of the gears may be provided so in a transverse direction of the Kombinierscheibeneinrichtung, along which the Querführungsnut, for example, straight, so no force transmitted by the cam on the Kombinierscheibeneinrichtung, since the cam in this direction along the Querführungsnut relative to move freely to this. In a vertical direction running perpendicular to the transverse direction, however, no such play is realized by the transverse guide groove, for example, so that during the rotation a force in the vertical direction is transmitted or exerted on the combination washer device. In particular, in the stowage position of the combiner disk device, the cam cams may be arranged in the vertical direction at a bottom dead center and / or in the position of use or one of the positions of use at a top dead center in the vertical direction. The lower

Dead center corresponds here to a 6 o'clock position, the top dead center of a 12 o'clock position of the driver cam. The two driving cams thus move the Kombinierscheibeneinrichtung in the vertical direction, ie in the vertical direction by the rotational movement of the gears. In this case, the cam cams move horizontally in a transverse direction along the Querführungsnut. If there is only one single transverse guide groove, then both driver cams engage in this guide groove. However, it can also be provided for each driver cam own Querführungsnut.

This has the advantage that the Kombinierscheibeneinrichtung can be moved in a very simple manner with few components in the vertical direction. The number of parts required by the direct engagement of the gears in the

Combination disc device further reduced. The gears themselves can namely directly or only with a minimum number of translation gears or

Components, for example, as explained below, a worm drive, are driven. Moreover, this results in the advantage that at a constant engine speed, when the stowage position of the bottom dead center is assigned, ie in the Stowing the driver cams are arranged in the vertical direction at the bottom dead center, the vertical acceleration of the Kombinierscheibeneinrichtung is initially small. This allows, for example, a coupling of a movable

Cover device to the same drive, as described below. Is the top dead center of the cam entrainment of the respective desired use position assigned, so can be in this set in the high direction, the position of the combiner particularly accurate, as in the vicinity of the top dead center, for example, in positions between the 1 1 o'clock and the 1 o'clock position, the vertical acceleration is also very low. Between the stowed and the use position the Ausfahrgeschwindigkeit the Kombinierscheibeneinrichtung is significantly larger. This behavior is particularly pleasant and also offers further advantages, as will be described again below. This is especially true for the exact positioning of the combiner in the position of use. Of course, the speed of the Kombinierscheibeneinrichtung can be further adjusted by an adapted speed of a drive motor of the drive device.

In a further advantageous embodiment it can be provided that the position of the trough of the contour ring on the rear side surface of the respective gear and the position of the cam on the front side surface of the respective gear at an angle between 70 ° and 1 10 ° in sbesondere between 80 ° and 100 ° offset from each other. Trough and entrainment cams can be around in the

Essentially offset 90 ° to each other. You can also nen offset by an angle between 85 ° and 95 ° to each other. The positions n can also be arranged offset by 90 ° to each other, for example, a driver cam can be arranged at a 6 o'clock position and the trough at a 9 o'clock position. The number of degrees can be determined here by measuring the angle between a plane passing through the trough the axis of rotation of the associated gear, and another plane passing through the cam and the axis of rotation of the associated gear.

This has the advantage that the Kipparme can be arranged laterally of the gears with a minimal space requirement and thereby in the stowed position of the

Kombinierscheibe, when the cam-cams are in the bottom dead center, also the above-described, particularly stable embodiment in the covering of the

Covering can be realized, in which the covering device can engage with particularly short fingers in the axial contour. This is also apparent from the figures again in more detail. In a particularly advantageous embodiment, it is provided that the two gears are designed to be identical and in particular engage each other. However, the two gears can not be made identical and intermesh. If the gears mesh with each other, then their directions of rotation are respectively

opposed.

This has the advantage that a variety of parts is reduced and at the same time over the

Ineinanderereifen also more example, translation gears can be saved. Thus, a compact design can be realized with a few different components.

In a further advantageous embodiment, it is provided that a rotation angle of at least one of the toothed wheels can be detected by a sensor device, in particular by means of a magnetic sensor device, which preferably has a Hall probe. In this case, the gear can have an element of the sensor device, for example a magnet.

This has the advantage that the position of the cover can be adjusted with high accuracy.

In a particularly advantageous embodiment, it is provided that the two gears are arranged between the tilting arms. The two gears can thus between two parallel planes in which the respective

Main extension directions of the respective Kipparme lie, be arranged.

This has the advantage that a particularly space-saving design can be achieved.

In a further advantageous embodiment it can be provided that a deflecting mirror is arranged on the covering device. By means of the deflecting mirror, projected image information can, for example, be deflected in the installation of the adjusting device in a head-up display.

This has the advantage of having a minimized number of components and

in particular with only a single drive motor, both a cover of the

Combination mirror device for protection against environmental influences in the stowed position as well as a movable mirror can be realized. Through the movable mirror or deflecting mirror can be an optical path depending on the position of the

Covering device, so depending on the covering position and release position of the cover and associated therewith also with the stowed and use position of the respective Kombinierscheibeneinrichtung, interrupted or produced. Thus, for example, an optical path between the Kombinierscheibe and a display element or a display device such as a TFT display for projecting an optical image information only in the release position and thus the

Use position of Kombinierscheibeneinrichtung be made. As a result, for example, the display device can be protected from strong solar radiation.

In a particularly advantageous embodiment, it may be provided that the two tilting arms are additionally connected to the cover plate by a cross member, which is spaced from the cover plate, and the deflection mirror is arranged on the cross member.

This has the advantage that the deflection mirror can be arranged particularly freely on the covering device and, moreover, the covering device is stabilized by the additional bracing, which is decisive for a deflection mirror in a head-up display device, in order to achieve a desired image quality.

In a further advantageous embodiment, it is provided that the deflecting mirror and a main extension plane of the cover plate at an angle between 70 ° and 1 10 °, in particular between 80 ° and 100 °, more preferably between 85 ° and 95 ° or at an angle of 90 ° to each other are oriented.

This has the advantage that the cover plate and deflecting mirror mechanically stabilize each other. Moreover, it has been found that the said relative arrangement is particularly advantageous in order to be able to cover the said shaft well on the one hand and on the other hand in the release position an optical path between a

Display device and the Kombinierscheibe to realize in which the

Cover is not in the way.

The invention also relates to a head-up display for a motor vehicle with an adjusting device according to one of the said embodiments.

In an advantageous embodiment, the head-up display has a

Display means for projecting optical information onto the combiner on. It is important that the deflection mirror is designed to direct the projected optical information in the release position to another mirror, in particular on the combination disc as a further mirror (namely as a combination mirror), or on a further deflection mirror. Under a deflection mirror can be understood here as opposed to a combination mirror a non-transparent mirror.

This has the advantage of being so elegant with a minimal number of

Components and drive motors, a cover is realized, which structurally automatically with a moving of the combining mirror the path for the

Combination releases and simultaneously with this movement an optical path between the display device, such as a backlit TFT display, and the Kombinierscheibe manufactures. Because of this optical path in the

Cover position and thus the stowage of Kombinierscheibe is interrupted, the display device is also protected from solar radiation.

The embodiments mentioned are thus directed to a kinematics for a

Cover the head-up display and with the protection of the display device. Through the cover while the shaft for the Kombinierscheibe or the

Combiner closed and opened. For this purpose, the cover can be tilted by the rotation of the gears about a rotation axis. This axis of rotation can each be at the end of the two tilted arms of the cover, which can be arranged laterally on the adjusting device in the transverse direction. The Kipparme may each have pins which offset from the pivot point at right angles to the corresponding

Stand out. These pins can be aligned radially to the gears. The gears may each have on a rear side or rear side surface on the outer edge a circumferential and axially projecting wall. In this wall, a groove can be embossed, in which the pin in the closed state of

Cover, in the cover position, can intervene. By rotating the gears in this case, the pin can be pushed out of the groove and axially in the direction of

Rotation axes of the gears are moved. The rotation can cause a tilting of the cover. The cover can also be used to tilt a deflection mirror, which is needed only in open operation. For this purpose, the deflecting mirror can be fastened to the cross member, which can be arranged between the tilting arms and held by them. As a result, in the closed state in the covering position of the deflecting mirror, the optical transmission path from a display device such as a TFT display to the combiner disk is interrupted be, whereby the display device can be protected from excessive sunlight.

The invention also relates to a motor vehicle with a head-up display according to one of the described embodiments or with an adjusting device according to one of the described embodiments.

1 shows a schematic representation of a motor vehicle with an exemplary embodiment of an adjustment device, which is integrated into a further exemplary head-up display device. In the motor vehicle 1, the head-up display 2 is arranged as usual in a direction of travel in front of a viewer 3, so that this at the same time an optical information from a motor vehicle. 1

area of an environment of the motor vehicle 1 and an optical information generated by the head-up display 2 can perceive.

The head-up display device in this case has an adjusting device 4 for adjusting a position of a combiner 5 of the head-up display 2. The

Combination 5 is part of a movable Kombinierscheibeneinrichtung 6, which in the present case also has a Kombinierscheibenträger 7.

The head-up display 2 in this case also has a drive device 8, by means of which the Kombinierscheibeneinrichtung 6 is movable relative to a support means 9.

In the example shown, the head-up display 2 also includes a covering device 10 for covering the combination disc device 6 when they are in one

Reservation is located. At this covering device 10 is present also a

Deflection mirror 1 1 is arranged, which directs optical information from a display device 12 via a further deflection mirror 13 on the combination disc 5 and thus to the viewer 3 in the position shown, the cover 10 and the Kombinierscheibe.

Details are shown here in the following figures.

In Fig. 2 is an exemplary embodiment of the adjusting device 4 in a

Shown top view. In the illustration, the x-direction corresponds to a transverse direction Q of the adjusting device 4. Correspondingly, the y-direction corresponds to one perpendicular thereto High Direction H. In the example shown, for the sake of clarity, the representation of the combiner disk device 6 (FIG. 1) is initially omitted. The

Representation is therefore rather focused on the drive means 8. In the present example, this comprises two toothed wheels 14a, 14b, which in the present case have the same construction and engage in one another. The respective rotation axes Ra, Rb run parallel to each other perpendicular to the xy plane in the z-direction. Accordingly, the two gears 14a, 14b are oriented coplanar here. You are too one

Main extension plane of Kombinierscheibeneinrichtung 6 and the Kombinierscheibe 5 coplanar, so oriented in parallel, which is clear in the following figures. The gearwheels each have a driver cam 15a, 15b, which is arranged on the front side surface of the respective gearwheel 14a, 14b, which in this case is facing the observer. In the example shown, the respective driver cam 15a, 15b is located here at a bottom, that is in the negative y-direction or high direction H dead center in the 6 o'clock position. This dead center can, for example, as will be explained in the following figures, the stowed position of the Kombinierscheibeneinrichtung 6 correspond.

If now the Kombinierscheibeneinrichtung 6 of the stowage position in a

Use position to be moved, the two gears 14a, 14b in

Movement offset, whereby the two cam cams 15a, 15b in the

Move high direction H in positive y-direction. Accordingly, the

Combination disc means 6 so that in the positive direction H of the

Move stowage to a use position. In the present case, the left-hand first gear 14a turns clockwise from the viewer and the second gear 14b, which engages directly into this first gear 14a, rotates counterclockwise.

As a result, the distance d between the two driver cams 15a, 15b, starting from the bottom dead center initially increased until it at a position of the cam cams 15a, 15b at 9 o'clock for the first cam 15a and at 3 o'clock for the second cam follower 15b reaches a maximum distance. If the Kombinierscheibeneinrichtung 6 further extended in the positive y-direction, so approach the two cam cams 15a, 15b again and the distance d decreases again. For example, the corresponding desired position of use can be achieved when the cam cams 15a, 15b have reached the top dead center, ie in each case the 12 o'clock position. At this point, the combiner disk device 5 (FIG. 3) is maximally extended in the vertical direction. In the example shown, the drive of the gears 14a, 14b is realized via an electric motor 16, which drives via a worm 17 of one, in this case the first gear 14a, the two gears 14a, 14b and thus also the corresponding remaining gear 14b, 14a. In the example shown, the worm 17 of the drive shaft 18 is displaceably mounted along the shaft 18. This ensures that with an external force, which acts on the Kombinierscheibeneinrichtung 6 and thus the gears 14a, 14b, not with a stationary drive or electric motor 16 to damage the gears 14a, 14b or the screw 17 leads, but rather the screw 17 on the shaft 18 present in the transverse direction Q is moved so far that the

Screw 17 and in this case the first gear 14a no longer interlock, so that the external force from the drive and the motor 16 is decoupled. In this case, a spring may be provided to hold the worm 17 in a desired for an adjustment of the position of the Kombinierscheibe 5 drive position. For the decoupling of the gears 14a, 14b of the drive and thus the electric motor 16 and the screw 17 so that the force resulting from the spring must be overcome by the external force before the screw 17 moves on the shaft 18.

Alternatively, such a protection by a rotatably mounted drive, for example, in the present case a rotatably mounted electric motor 16 which is a

Rotary axis is rotatably mounted such that a drive, in this case the screw 17, is pivoted relative to the gear 14a and thus mechanically from the

Kombinierscheibeneinrichtung 6 and the gears 14a, 14b is decoupled.

In Fig. 3, the exemplary embodiment of Fig. 2 is shown in an oblique view. Here, the Kombinierscheibeneinrichtung 6 is shown here. This is in the example shown in a stowed position 27 and is thus present in a shaft 19, which is limited here on three sides by the support means 9, arranged. The support device 9 in the present case perpendicular to

High direction, ie in a zx plane, a U-shaped cross-section. In this case, the axes of rotation Ra, Rb of the two gears 14a, 14b extending in cross section through the bottom leg of the U, so that the two gears 14a, 14b in the example shown in the shaft 19 between the Kombinierscheibeneinrichtung 6 and the

Bottom leg of the support device 9 are arranged.

In the lateral limbs of the U-shaped support means 9 is at the

Each inside a longitudinal guide 20a, 20b arranged. The longitudinal guide grooves 20a, 20b in each case have an end portion 21a close to the stowage location, a central area 22a and an end area 23a close to the use position. In the example shown, the longitudinal guide groove 20a, 20b in the Verstaustellungsnahen end portion 21 a and the central region 22a in the y-direction straight, ie parallel to the main plane of the Kombinierscheibeneinrichtung 6. In the

Near the end of use 23a, the longitudinal guide groove 20a is also straight or rectilinear, but relative to the main plane of extension

Kombinierscheibeneinrichtung 6, so tilted to the xy plane. As a result, as shown in the following figures, a use position or a plurality of use positions with different inclinations of the combiner 5 can be realized.

In the present case, the combination disk device 6 comprises the combination disk 5 and the combination disk carrier 7. The combination disk device 6 has a transverse guide groove 24 which extends in the transverse direction Q in a presently lower edge region, ie an edge region of the combination disk carrier 7 facing away from the combination disk 5 the edge 25 extends. In the present case, the transverse guide groove 24 is open in a middle region 26 downwards, that is to say towards the edge 25. As a result, when the distance d of the cam cams 15a, 15b falls below a minimum distance e, which corresponds to the width of the central region 26, the cam cams 15a, 15b are executed and / or inserted into the transverse guide groove 24. Thus, the Kombinierscheibeneinrichtung 6 can be replaced without much effort by the gears 14 a, 14 b in a

corresponding service position are brought, in which the distance d is just smaller than the said minimum distance e. This is explained below.

In the present case, the transverse guide groove 24 is embodied in two end regions 27a, 27b which are separated from the middle region 26 in accordance with a dead end, that is to say in particular in contrast to the central region 25, closed towards the lower edge. The transverse guide groove 24 can thus be described as a two-part transverse guide groove 24. It extends here in the transverse direction Q straight over a majority, in this case more than 80 percent, the width of

Kombinierscheibeneinrichtung.

In the present case, the combination disk device 6 is guided into the longitudinal guide grooves 20a, 20b via respective pins 30a, 30b, 31a, 31b (FIG. 5), which can still be seen in later figures. For example, these pins 30 a, 30 b, 31 a, 31 b may be arranged on the Kombinierscheibenträger 7. It may for example be provided that two pins 30a, 30b, 31a, 31b engage in each case one of the two longitudinal guide grooves 20a, 20b. For improved guidance of the Kombinierscheibeneinrichtung 6 while a distance of the pins 30 a, 30 b, 31 a, 31 b in the vertical direction H should be as large as possible.

In Fig. 4, the embodiment of Fig. 2 and Fig. 3 with the

Combination disc device in a first and a second position of use. In this case, in the first position of use 28a, the combiner 5 is extended out of the shaft 19, but not tilted, so in this case arranged parallel to the xy plane, and thus also parallel to the plane of the main plane of the Kombinierscheibeneinrichtung 6 in the stowed position 27. Here are the Mitnehmer- cams 15a, 15b does not reach here in a top dead center. Accordingly, the mentioned in the last description of figures and later pins 30a, 30b, 31a, 31b of Kombinierscheibenträgers 7, which engage in the Längsführungsnut 20a, 20b, in the first use position 28a are still in the central region 22a arranged, for example in one 10 o'clock or 2 o'clock position.

In the second position of use 28b, however, the Kombinierscheibe is tilted in comparison to the Kombinierscheibe 5 in the first position of use 28a and pushed by the height h upwards. The cam cams 15a, 15b have therefore been moved further in the vertical direction H than in the first position of use 28a. This has the consequence that a respective upper pin 30a, 30b (Figure 5) of the Kombinierscheibenträgers 7 is already disposed in the angled end portion 23a of the longitudinal guide rail 20a, a corresponding lower pin 31 a, 31 b (Figure 5), however, for example, here still in the parallel to the xy plane extending central region 22a.

As a result, the tilting of the Kombinierscheibe 5 is achieved relative to the xy plane. The maximum tilt angle is determined in the present example by the angle of tilting of the end portion 23a relative to the central region 22a.

The fact that the tilt is also accompanied by the displacement of the Kombinierscheibe 5 by the height h, a constructive height compensation can be realized: In a tilting of the Kombinierscheibe 5 without change in height namely changed due to the changed geometry and a point of impact of a

Light beam 29 on the Kombinierscheibe 5, and more so, the more obliquely the light beam 29 impinges on the Kombinierscheibe 5. This impact point is corrected by the extension of the Kombinierscheibe 5 in the tilting again. at

appropriate interpretation of the geometry of the adjusting device 4 and a corresponding arrangement of an associated display device can also the the otherwise required when tilting a Kombinierscheibe 5 in a head-up display 2 software correction for the displayed image information.

In Fig. 5 is the exemplary embodiment of the previous figures with the

Kombinierscheibeneinrichtung 6 shown in the second stowed position. In addition, now also in the Längsführungsnuten 20a, 20b engaging pins, namely the upper pin 30a for engaging in the first Längsführungsnut 20a and the lower pin 31 a for engaging in the first Längsführungsnut 20a and the upper pin 30b and the lower pin 31 b illustrated for engaging in the second longitudinal guide groove 20b. Since the upper pin 30a, 30b now in the near-use end near end portion 23a and 23b, in which present the two

Längsführungsnuten 20a, 20b are tilted, is also the

Kombinierscheibeneinrichtung 6 and the Kombinierscheibe 5 tilted out of the viewing plane out.

Since the two cam lobes 15a, 15b are not present at the top

Dead center, are located at the 12 o'clock position, but approximately at a 1 1 Clock or 1 o'clock position for the first driving pin 15 a and the second driving pin 15 b, the Kombinierscheibeneinrichtung 6 also further up in the vertical direction H, ie in positive y Direction. Thus, the Kombinierscheibeneinrichtung 6 in the present case can be further tilted. The degree of tilt is determined by the inclination of the Längsführungsnuten 20a, 20b in the respective end regions 23a, 23b. The tilting of the

Combination disc means 6 takes place about a first tilt axis Ka, which in this case passes through the lower pin 31 a, 31 b and thus not fixed locally, but with the pin 31 a, 31 b relative to the support means 9 variable.

Since the cam lobes 15a, 15b naturally move much slower in the high direction H near top dead center than at the 3 o'clock or 9 o'clock position, rotation of the gears 14a, 14b results in the same angular amount in the vicinity the use position to a slower movement of the Kombinierscheibeneinrichtung 6 than in an intermediate region between the stowage position 27 and the use position 28a, 28b. Thus, in the embodiment shown, a plurality of different use positions 28a, 28b can be set very precisely with different tilt angles. For the most accurate positioning or position determination of the gears 14a, 14b, a sensor or a sensor device may be provided which, for example, between the respective gear 14a, 14b and

Carrier device 9 is arranged. For example, a magnet may be mounted on the gearwheel 14a, 14b or a shaft of the gearwheel 14a, 14b, so that the rotational angle can be measured by means of a Hall sensor arranged on the carrier device 9. With a maximum tilting of the Kombinierscheibe 5 by 4 ° can with a resolution of about 30 steps different use positions with

different angles, which, for example, corresponding to 1 °

can be adjusted. In this case, about 30 ° of the rotation of the two gears 14a, 14b account for the different positions of use. This is not a problem since the said 30 ° in the vicinity of the top dead center correspond to only a small stroke in the vertical direction H. The corresponding required resolution of the position determination of the gears of 1 ⁰ can be realized with commercially available Hall sensors.

FIG. 6 shows a further exemplary embodiment of an adjustment device with the combination lens device in a use position in a plan view. Similar to the example shown in Fig. 5, here in the tilted

Position of use 28b a tilt angle of the Kombinierscheibe 5 by a positioning of the cam cams 15a, 15b in the last 30 ° from the top dead center, ie in the range between 1 1 and 12 clock or 1 and 12 clock are set.

In contrast to the embodiment shown in Fig. 5, however, the tilting takes place here about a second tilting axis Kb, which in this case extends through the upper pin 30a, 30b of the Kombinierscheibenträgers 7. In this case, a tilting of the Kombinierscheibe 5 can be realized without a tilted Längsführungsnuten 20a, 20b must be present in the near-use end portion 23a, 23b of the Längsführungsnuten 20a, 20b. Rather, the guide grooves 20a, 29b may be straight there in the end region 23a, 23b and extend in the xy plane, ie parallel to the main extension plane of the combination disc device 6 in the

Stowage 27. The upper pins 30a, 30b can thereby be brought to a stop. In order to realize the described tilting, corresponding to the lower edge 25 of the Kombinierscheibenträgers 7 in the z-direction, that is to be moved out of the plane or in this. This can be made possible by a corresponding configuration of the longitudinal guide grooves 20a, 20b. Optionally, 31 b may be provided for the upper pins 30 a, 30 b and for the lower pin 31 a different Längsführungsnuten.

In addition, a guide and thus movement of the Kombinierscheibeneinrichtung 6 by a corresponding design of the Querführungsnut 24 and the cam cams 15a, 15b may be provided. For example, the driver cams 15a, 15b can be conical and thus the combination lens device 6 can be pushed out of the plane of the drawing on the combination plate carrier 7

or pull into it. The same can be realized by a guide rail within the transverse guide groove 24, which engages in the cam cams 15a, 15b and within the Kombinierscheibeneinrichtung in a depth direction parallel to the axes of rotation Ra, Rb, ie the z-direction runs. In the

described further embodiment remains the Kombinierscheibe. 5

arranged largely at the same height, since it does not move in the vertical direction during the tilting or the second tilting axis Kb is not automatically moved in the vertical direction during tilting.

In Fig. 7, the adjusting device of Fig. 2 to 3 is shown with a service position of the gears in a further plan view. To achieve the service position, in the present case, the first gear 14a has been rotated clockwise beyond the top dead center at 12 o'clock, and correspondingly the second gear 14b counterclockwise above the top dead center and thus the position of the gears corresponding in the use position or positions 28a, 28b 14a, 14b turned away. In the present case, the driver cams 15a, 15b are respectively positioned in the 1:30 o'clock position and 10:30 o'clock position.

In the mentioned service position, the distance d between the two driver cams 15a, 15b is smaller than the width e of the central region 26 of the transverse guide groove 24 of the combination disk device 6. The distance d between the driver cams 15a, 15b can be here as well as independently from the one described here

Embodiment in the other places between two each other

remote, ie oppositely oriented sides of the cam cams 15a, 15b are measured. The fact that this distance is now less than the width e of the downwardly open central region 26 of the transverse guide 24, can now

Kombinierscheibeneinrichtung 6 upwards in the vertical direction H, ie in the positive y direction, drawn beyond the use position or use positions 28a, 28b out of the shaft 19 and thus removed from the support means 9. This allows the Kombinierscheibeneinrichtung 6 easily replaced or replaced or adapted to a different vehicle type.

A comparable service position of the gears 14a, 14b can also be achieved in the vicinity of the bottom dead center or from the bottom dead center of the two driver cams 15a, 15b, since the distance d of the two driver cams 15a, 15b, for example, at a position on 4th : 30 o'clock or 7:30 o'clock for the first cam-cam 15a and second cam-cam 15b is identical to the distance in the position at 1: 30 o'clock or 10:30 o'clock. In any position, however, the Kombinierscheibeneinrichtung 6 in the vicinity of

Stowage 27 (Fig. 3) arranged so that they may not protrude from the shaft 19 and is correspondingly difficult to replace.

In principle, a similar mechanism would also be conceivable with a reverse designed transverse guide groove 24, which is open in the two end regions 27a, 27b and closed in the central region 26. In this case, the

Service position of the gears then, for example, at 1 1 clock for the first gear 14a with the first cam 15a and at 2 o'clock for the second gear 14b with the second cam 15b. In this case, however, in an operating mode with a reciprocating cam follower 15a, 15b between lower and upper dead center, the distance d is reduced in each case in an intermediate position and compared to the proposed solution is significantly smaller (compare, for example, the Distance of the cam cams 15a, 15b in Fig. 5), the leadership of Kombinierscheibeneinrichtung 6 is much shakier and prone to tilting.

Thus, the embodiment shown is where a finger 33a, 33b extends from a respective lateral edge 32a, 32b along the respective end region 27a, 27b of the transverse guide groove 24 to the central region 26, and in each case into the end region 27a, 27b the lower edge 25 of the Kombinierscheibeneinrichtung 6 and the Kombinierscheibenträgers 7 forms, particularly advantageous. Also, in the example shown symmetry with respect to a

Main extension plane of Kombinierscheibeneinrichtung 6 and the transverse direction Q perpendicular plane of symmetry S, which in this case runs parallel to an xz plane, is advantageous here. Thus, for example, the two gears 14a, 14b can be designed to be identical and a uniform

Moving the Kombinierscheibeneinrichtung 6 can be realized in the vertical direction H. In Fig. 8, another exemplary embodiment of an adjusting device for a head-up display or a head-up display is shown in a side view.

In addition to the components known from FIGS. 2 to 5, a movable cover device 34 is presently arranged on the carrier device 9. The

Cover 34 has a cover plate 35 with two arranged on this plate Kipparmen 36a, 36b. These two tilting arms 36a, 36b are each tiltably or rotatably mounted at a pivot point Da or Db, which is arranged in an end region of the respective tilting arm 36a, 36b remote from the cover plate 35. Through the two pivot points Da, Db a corresponding axis of rotation D.

Shown is the adjusting device 4 now with the Kombinierscheibeneinrichtung 6 in the stowed position 27 and accordingly the cover 34 in one of

Stowage 27 associated covering position 37. In this, the shaft 19, in which presently the Kombinierscheibeneinrichtung 6 is stowed in the stowed position 27, covered.

In this case, the cover plate 35 is arranged in the covering position 37 with the xz plane as the main extension plane. The two tilting arms 36a, 36b extend mainly in the vertical direction H, ie they have the y-direction as

Main extension direction, and are here, starting from the cover plate 35 on a side wall, which is formed by the respective side legs of the U of the support means 9 along. The support device 9 is thus at least partially between the cover 34, in this case the Kipparmen 39a, 39b and the Kombinierscheibeneinrichtung 6 and the gears 14a, 14b arranged.

In Fig. 9, the embodiment of Fig. 8 is also shown, in which case the

Combination disc device 6 is shown in the untilted position of use 28a. Accordingly, the cover 34 is now arranged in one of the or the use positions 28a, 28b associated release position 38 and thereby releases the shaft 19. In the release position 38, the covering device 34 is now tilted about the axis of rotation D passing through the two pivot points Da, Db.

In Fig. 10 is now the adjusting device of Fig. 8 and Fig. 9 with the

Kombinierscheibeneinrichtung 6 shown in the tilted position of use 28b. In this tilted position of use 28b of the Kombinierscheibeneinrichtung 6 is here again associated with the release position 38 of the cover 34. In this position, as well as in Fig. 9, an opening 39b in the side legs of the here U-shaped support means 9 is shown. Through this opening 39b in the side leg, a finger, which is shown in FIGS. 11 and 12 and also explained there in more detail, can be arranged in contact with the toothed wheel 14a through the carrier device 9.

As a result, tilting of the covering device 34 from the covering position 37 into the release position 38 can be implemented by moving the toothed wheels 14a, 14b. This mechanism will be explained in more detail with reference to FIGS. 11 and 12.

Fig. 1 1 shows the exemplary embodiment of Fig. 8 in a perspective oblique view. For better clarity while the carrier device 9 is hidden. Thus, on the one hand, the pins 30a, 30b, 31a, 31b, partially not shown in the other figures, through which the combination disc device 6 is guided in the longitudinal guide grooves 20a, 20b, can be clearly seen again. Also, so the two fingers 40a, 40b of the cover 34 can be seen. These are arranged on the two tilting arms 36a, 36b respectively on the inside, ie on a side facing the respective other tilting arm 36a, 36b, of the corresponding tilting arm 36a, 36b. You are present between the pivot point Da, Db,

or the axis of rotation D and the cover plate 34 on the respective Kipparm 36a, 36b. In the example, the two fingers 40a, 40b extend mainly in a direction perpendicular to the main extension direction of the two tilting arms 36, 36b. In the present case extend both elements, the tilting arms 36a, 36b and the fingers 40a, 40b parallel to the xy plane, and are each at a right angle to each other. In this case, the two fingers 40a, 40b are also arranged radially to the two gears 14a, 14b.

The two gears 14a, 14b are presently seen with a rear or rear side surface. This is in the opposite direction to the front side surface, which can be seen in the previous figures and on which in the illustrated embodiments, the cam cams 15a, 15b are arranged. On the side surfaces shown, the two gear wheels 14a, 14b each have a contour ring 41a, 41b, on which the covering device 34 in the present case rests with its fingers 40a, 40b upon rotation of the gear wheels 14a, 14b. The contour rings 41 a, 41 b in the present case comprise a wall which extends radially in each case starting from the rear side surface in a wall height w over the rear side surface. In this case, the contour rings in the axial direction of the respective gear 14a, 14b on a respective trough 42a, 42b, on which the wall height w is reduced, in the present case to zero is reduced. In this particular trough 42a, 42b, in the present case, the covering device 34 engages in the covering position 37 with the respective finger 40a, 40b. It can the

Cover 34 may be arranged in contact with the respective contour ring 41 a, 41 b.

In FIG. 12, similar to FIG. 1, the adjusting device from FIG. 8 is shown in a perspective view with the carrier device hidden. In contrast to FIG. 1 1, the covering device 34 in the untilted position of use 28 a and correspondingly the covering device 34 in the release parting 38 are shown. The two gears 14a, 14b are rotated accordingly, in the present case by 150 ° in comparison to Fig. 1 1. Accordingly, the two wells 42a, 42b are no longer at the height of the two fingers 40a, 40b, but in the example shown at 2 o'clock for the second gear and at 10 o'clock for the first gear 14a. Accordingly, the fingers 40a, 40b now no longer in the trough 42a, 42b arranged, but at the raised by the wall height W relative to the side surface and the bottom of the trough portion of the contour ring 41 a, 41 b. Accordingly, the fingers 40a, 40b are therefore pushed out in the z-direction, which in turn resulted in a rotation of the cover 34 about the axis of rotation D due to the fixed pivot points Da, Db.

Starting from the covering position 37 shown in FIG. 11 and the above-described position of the toothed wheels 14a, 14b, the respective fingers 40a, 40b from the trough 42a, 42b and thus the covering device 34 are thus rotated by rotating the toothed wheels 14a, 14b z direction pushed out. Thus, the shaft 19 is released here, so that the Kombinierscheibeneinrichtung 6 can go unhindered in the use position 28a. Since, when the covering position 38 is reached once by the cover 34, a further displacement is not required, the contour rings 41 a, 41 b to the trough 42 a, 42 b here consistently with the same wall height w and corresponding to one except for the troughs 42a, 42b provided planar contour. Thus, for example, the Kombinierscheibeneinrichtung 6 from the use position shown 28a by further rotation of the gears 14a, 14b in the tilted

Be used position 28b, without being in the present case the

Cover 34 further moved. A move back in a process of the Kombinierscheibeneinrichtung 6 in the stowed position can be realized for example by a spring, which then pulls the cover 34 and thus the fingers 40a, 40b back into the troughs 42a, 42b.

It is particularly advantageous that, for example, when in the stowed position 27, the cam cams 15 a, 15 b are in a bottom dead center, the movement of the Combination disc means 6 in the vertical direction at the beginning is extremely slow, so that the cover 34 has enough time to release the shaft 19, not shown here not.

FIG. 13 shows an exemplary embodiment of a head-up display in a perspective side view. The head-up display 2 comprises

For example, here an adjusting device 4 as shown in FIGS. 8 to 12. In addition, a cross member 43, which connects and stabilizes the two tilting arms 36a, 36b, is disposed on the covering device 34 between the arms 36a, 36b. At this cross member 43 in the present case, a deflecting mirror 1 1 is arranged. Whose main extension plane is in this case oriented perpendicular to the cover plate 35. In the example shown here the Kombinierscheibeneinrichtung 6 is shown in a tilt-free position of use 28a and corresponding to the cover 34 in the release position 38. As a result, in the present example, the deflection mirror 1 1 is arranged such that a light beam 29 from a display device 12, which is designed for example as a backlit TFT display, from the deflecting mirror 1 1 to a further mirror 13 and is directed by this on the Kombinierscheibe 5 , In this way, in the release position 38, optical information can be projected from the display device 12 onto the combiner disk 5 and thus to a viewer 3 (FIG. 1) via the deflection mirror 11. Thus, an optical path from the display device 12 via the deflecting mirror 1 1 to the Kombinierscheibe 5 is made.

In Fig. 14, the exemplary head-up display of Fig. 13 is the same

Perspective shown. In the present case, however, the Kombinierscheibeneinrichtung 6, of which only the Kombinierscheibe 5 is visible here, arranged in the stowed position 27. Accordingly, the cover 34 is disposed in the cover 37. Thus, the shaft 19 is covered and the Kombinierscheibeneinrichtung 6 protected from external forces. In addition, such a further light 44, which impinges on the further mirror 13 from one environment, can not be deflected onto the deflecting mirror 11 and thus also into the display device 12, since with the changed position of the covering device 34 also the transverse support 43 and thus the deflection mirror 1 1 is arranged in a different position and a different orientation. This also an optical path from the display device 12 via the deflecting mirror 1 1 is interrupted to the Kombinierscheibe 5. Thus, in addition to the combiner disk device 6, the display device 12 is also protected for projecting optical information onto the combiner disk 5, namely, for example, from fading by sunlight exposure.
