Definitions
- the invention relates to a turntable with a rotary ring rotatable about a dome, which has a setting pointer, which is illuminated from the interior of the dome.
- the invention also relates to a control unit for motor vehicles, comprising such a turntable.
- the strong distribution of light over large areas and the associated attenuation of intensity are problematic in a majority of prior art turntables.
- the solution to this problem is especially difficult if the turntable is to be designed as a movable ring, which rotates around a fixed housing or a fixed dome. In this case, it is not readily possible to carry a light source with the rotary ring, without restricting the angular range in which the turntable would be rotatable.
- Object of the present invention is therefore to provide a turntable, which overcomes these disadvantages.
- the turntable according to the invention initially has a rotary ring which surrounds a dome.
- This dome is advantageously carried out fixed.
- turntables which are rotatably arranged within a fixed scale, results in the turntable according to the invention a particularly convenient and clear operation.
- the rotary ring is rotatable about the dome at least in an angular range.
- the rotary ring can thus be rotatable in a sector of less than 360 ° or 360 ° or even more than 360 °.
- the angular range results from the use of the turntable according to the invention.
- the rotatability of the rotary ring can be angularly unlimited, which is particularly useful for applications where the user selects with the turntable discrete alternatives and should be able to switch from one to another alternative always in the same direction.
- the turning ring can partially or completely circumscribe the cathedral.
- a setting pointer is arranged, on which the position of the rotary ring is recognizable. If symbols or a scale are arranged on the dome, then the turning ring can be turned so that the setting pointer stands on a symbol or a portion of the scale on the dome.
- the setting pointer can be illuminated with the same intensity in every position of the rotary ring, with the highest possible intensity being sought here.
- the dome is at least partially translucent, wherein the light transmittance is preferably realized in a region through which is lit from the inside of the dome ago on the setting pointer.
- the turntable has a light guide coupled to a light source, which has a light exit surface arranged inside the dome.
- the light exit surface is in this case arranged so that light emerging from it passes through the wall of the dome on the set pointer.
- the light directly and directly passes through the wall of the dome in sufficient luminosity and without previous reflection. This is advantageous because the luminous intensity is attenuated by multiple reflection.
- the turntable according to the invention now has a coupling device which couples the rotary ring with the light guide so that the light exit surface of the light guide is arranged in each position of the rotary ring facing the set pointer so that emerging from the light exit surface Light falls on the set hand. So will the Turning ring, on or in which the setting pointer is arranged to rotate around the cathedral, moves within the dome, the light exit surface of the light guide so that light emerging from the light exit surface of the light guide always falls on the set pointer.
- the wall of the dome is preferably designed to be translucent at least in those areas in which the setting pointer, if it is located in these areas, must be illuminated.
- the dome may have a translucent window encircling it along its wall at the level of the actuator. This window can completely circulate in the wall of the cathedral or circulate in sections.
- the coupling device is designed so that it moves the light guide during movement of the rotary ring so that its light exit surface faces the set pointer in the rotary ring.
- a particularly simple and cost-effective implementation of such a coupling device can be achieved if the coupling device couples the light guide with the rotary ring through an opening in the dome. This opening in the dome can be arranged in its side wall. If the coupling device is arranged in an opening in the dome, a flatter construction of the turntable, i. a smaller extension in the direction of the axis of rotation can be achieved.
- the coupling device has or is a gear arrangement.
- the coupling device may have one, two or more gears. These gears allow a coupling with little play and allow by a suitable choice of the translation of the light guide to carry the set pointer according to the desired conditions.
- a particularly space-saving realization of such a gear arrangement is possible if a part of the light guide itself is designed as a gear or the light guide has a gear which is rotatable about a gear axis parallel to the axis of rotation or on the axis of rotation.
- This gear axis is the axis of rotation of the rotary ring, the smaller the turntable can be designed.
- the rotary ring has on its inner side facing the axis of rotation a toothed rim circulating in a plane perpendicular to the axis of rotation.
- the ring gear can completely rotate the rotary ring or sections.
- a coupling of the rotary ring with the light guide can now be achieved in that a first, outer gear meshes with the ring gear of the rotary ring, and a second, inner gear meshes with the gear of the light guide and the two gears mesh.
- This arrangement of gears can then pass through the opening in the dome from the inside of the dome to the outside to the rotary ring.
- the rotary ring is thus coupled through the wall of the dome with the light guide.
- the gears may here all or partially be designed as multi-stage, in particular as two-stage gears. This makes it possible to choose the translation so that the light guide always rotates at the same angle as the rotary ring.
- the outer gear can engage with a first sprocket in the sprocket of the rotary ring and with a second sprocket in a first sprocket of the inner gear.
- This inner gear can in turn engage with its second sprocket in the gear of the light guide.
- both the dome and the rotary ring are designed axially symmetrical.
- Symmetry axis of the axial symmetry is the axis of rotation of the rotary ring, around which the rotary ring is rotatable.
- the longitudinal extent of the rotary ring is in this case in a plane perpendicular to the axis of rotation.
- a particularly good readability and robustness of the turntable is achieved when the rotary ring is substantially positive fit against the dome.
- the dome can on its not covered by the rotary ring top, so the side with which it protrudes over the rotary ring in the direction of a user, have a scale or positioning symbols.
- the setting pointer is arranged in the rotary ring in such a way that it passes light through the rotating ring.
- the setting pointer thus has a light entry surface and a light exit surface, wherein the light entry surface protrudes on an inner side of the rotary ring facing the rotation axis of the rotating ring and the light exit surface emerges on another side, which is visible to a user from the outside.
- the light entry surface of the rotary pointer is then arranged so that light emerging from the light exit surface of the light guide falls onto this light entry surface of the setting pointer.
- the light guide preferably has a first elongate region in which it extends on or parallel to the axis of rotation of the rotary ring. With this range, the light guide can be partially disposed within the cathedral, partly outside the cathedral. Preferably, this first elongated region ends at a light entry surface, which is arranged opposite a light source so that light emerging from the light source at least partially falls on this light entry surface.
- the light guide has a relative to the first region angled second region which includes an angle with the first region and thus with the axis of rotation of the rotary ring.
- this second, angled region to the axis of rotation radially, ie, perpendicular.
- the first and the second region of the light guide is preferably configured so that in the first region parallel to the axis of rotation directed light is totally reflected in the second region, so that it continues parallel to the longitudinal direction of the second region.
- the area between the first and the second area can be flattened on the outside of the angle enclosed by the two areas.
- the light guide can have an additional exit surface for illuminating this scale.
- the turntable according to the invention can be used wherever devices are operated by turntable.
- the turntable can be connected by a suitable connecting device with the unit to be controlled.
- This connecting device transmits the position of the rotary ring to the size to be controlled. It is conceivable, for example, grinding potentiometer or contacts that close in certain positions of the rotary ring.
- heaters and air conditioning systems in particular in motor vehicles, come into question as devices to be operated.
- Other components of a motor vehicle can be operated with the help of such a turntable.
- a continuous quantity, such as temperature, or discrete quantities, such as the direction of an airflow or the stage of a blower, may be controlled.
- FIG. 1 shows a vertical section through a turntable according to the invention according to section AE (see FIG. 2 ).
- a dome 13 is in this case surrounded by a rotatable rotary ring 3. Inside the dome 13, a light guide 7 is arranged, which is rotatable in the dome 13 about the axis 14. The axis of rotation 14 is at the same time also the axis of symmetry of the substantially circular dome 13.
- the rotary ring 3 has a setting pointer 1, which passes through the rotary ring 3 and light from the dome 13 facing the inside of the rotary ring 3 to the cathedral 13 facing away from the outside of the rotary ring 3 shine through or passes.
- the light guide 7 has a light exit surface 15, which faces the set pointer 1.
- the light guide 7 therefore conducts light from a light source 8, for example a light-emitting diode, to the light exit surface 15, where the light strikes the set pointer 1 through the dome 13. So that the light emerging from the light exit surface 15 of the light guide 7 can strike the setting pointer 1, the dome 13 has a transparent region 4, which completely or partially revolves the axis 14.
- the light guide 7 is substantially L-shaped in the example shown. In this case, one leg of the L runs towards the light source 8, while the other leg tapers onto the transparent area 4 of the dome 13 and ends in the light exit area 15.
- the rotary ring 3 is rotatable about the axis 14. For this purpose, it is locked in a housing 12 so that it is not movable in the direction of the axis 14, but is rotatable about the axis 14. According to the invention, the light guide 7 is now so with the Rotary ring 13 coupled so that it rotates about the axis 14 with the rotary ring 3 at the same angles as this.
- the leg of the L which ends in the light exit surface 15, is perpendicular to this other leg, so that the light exit surface 15 with the rotary ring 3 about the axis 14 moves.
- the coupling of light guide 7 and rotary ring 3 takes place in the example shown via a gear mechanism with gears 6, 9 and 10.
- the rotary ring 3 has an internal toothing 2, in which a two-stage gear 10 engages.
- the gear 10 is in this case disposed in an opening of the mandrel 13, so that a part of the gear 10 is located inside the mandrel 13 and a part of the gear outside the mandrel 13.
- This two-stage gear 10 in turn engages in a multi-stage gear 9, which is arranged in the interior of the dome.
- This gear 9 now engages in a gear 6, which surrounds the light guide 7 about the axis 14.
- the gear 6 is thus arranged around the light source 8 facing legs of the light guide 7.
- the gear 6 may be materially connected to the light guide 7. Now, if the rotary ring 3 is rotated about the axis 14, so turns into the ring gear 2 cross-two-speed gear 10. Its rotation is transmitted to the engaging in the gear 10 two-stage gear 9. This two-stage gear 9 then transmits the rotation to the gear surrounding the optical fiber 6, so that the optical fiber rotates when the rotary ring 3 rotates.
- the two-stage gear 9 as well as the two-stage gear 10 in this case each have sprockets, whose circumferences parallel to each run around the same axis of rotation.
- the circumference of the partial gears is in this case selected so that the light guide 7 always rotates at the same angle as the rotary ring 3. In this way, the light exit surface 15 in the interior of the dome 13 is always facing the set pointer 1.
- the dome 13 has a symbol cap 5 in the present example on, which is plugged onto the cylindrical side wall of the dome 13.
- the cylinder axis of the cylindrical side walls here is the axis 14.
- a translucent scale, not shown here is housed. This can be illuminated from inside the dome 13.
- the light guide 7 may have a scattered light exit surface 16, from which light is emitted from the light guide 7 in the direction of the symbol cap 5.
- the turntable shown is positioned over a housing 12 to a circuit board 11 via which the light source 8 is contacted.
- FIG. 2 shows a horizontal section of the turntable according to the invention according to section FF (see FIG. 1 ).
- the turntable is essentially circularly symmetrical.
- the rotary ring 3 is arranged, in which the setting pointer 1 is arranged.
- the rotary ring 3 is rotatable in the plane of the drawing.
- a first gear 10 engages, which is arranged partly outside the dome 13 and partly within the dome 13.
- This two-stage gear 10 engages in the two-stage gear 9, which in turn engages in the surrounding the light guide 7 gear 6. If the rotary ring 3 is moved, the gears 10, 9 and 6 transmit this rotation to the light guide 7, whose light exit surface 15 thereby always faces the set pointer 1.
