Definitions
- the invention relates to an arrangement for illuminating the control knob Input unit by means of transmitted light, the input unit being one has a partition attached rotary switch, the knob reaches through the supporting shaft on the opposite side of the partition and where at least one light source located on the side of the rotary switch is provided.
- the transmitted light illumination of the control knobs of the input devices a partition should be problematic insofar as in contrast to one commercial and ready-to-install device assembly of input unit, Adjustment button and light guide must be done directly on the partition. Because of the dominance of such lighting at night, there are some uniform illumination of a control knob, be it that it as a whole or should only shine in an edge area or markings or scales of the control button should be made clear to make high demands. On the other hand, in particular for the lighting of the control knob the conditions when using the adjusting unit in the motor vehicle large series production and large series assembly.
- the object of the present invention was therefore with the lowest possible Effort the control knob of a partition of the generic type to illuminate the assigned input unit by means of transmitted light.
- the solution to the problem is characterized in that an optical fiber it is provided that on the light guide one to be examined Area of the adjusting knob is designed corresponding light-conducting surface, that the light guide is fastened to the partition on the knob side and that the light guide reaches through the partition onto the light source.
- a preferred embodiment provides that the rotary switch Printed circuit board is assigned as a light source on the printed circuit board Contacted light-emitting diodes and that the light guide serve as a conical ring with molded in the axial direction and assigned to the light diodes, is formed light-guiding extensions.
- the decisive advantage that the invention offers is that only a single light-guiding and manufactured by injection molding Component for the light guidance between the light source and the control knob is required and that homogeneous lighting of the control knob, in In the case of the exemplary embodiment, one provided on the adjusting knob revolving, for example the switching steps of the rotary switch optically emulating row of luminous dots, with only three light-emitting diodes can be realized.
- the The light guide according to the invention in a simple manner, that is to say indirectly when Attach the input unit can be attached.
- the light guide represents in the particularly advantageous coaxial arrangement, according to the Embodiment, so to speak, an washer, the Flange surfaces are not optically relevant.
- the light guide provided within the light guide only a few optically effective areas, that is, areas higher Requires surface quality.
- the light guide in the Interact with the one located in the partition Bulges provided through opening or with the Bores assigned to through holes, which are used for reaching through the light guide channels or the light-guiding extensions of the light guide are provided to prevent rotation of the input unit when a housing is assigned to the rotary switch and the attachment of the Input unit by means of a trained on the housing Thread approach takes place. Due to the anti-rotation function, reduce the fastening torque and in this way for that Input unit accommodating plastic housing a damage-free and achieve creep-resistant fastening.
- the scale of a rotary switch with limited rotation angle on the same way can be illuminated by transmitted light, for such sectoral lighting, if necessary, only two or only one light-emitting diode must be provided as a light source. Otherwise they are different light rings or scale designs, for example also rows of symbols in the manner according to the invention by means of transmitted light illuminable. The same applies to different types of control knobs.
- each deflection surface guides the received one Light in an asymmetrical with respect to the ring shape of the light guide Section of the ring, causing an overlap of the light fluxes two neighboring deflection surfaces. This also adds to the benefit achieved differences in brightness between the used LEDs are compensated.
- the theoretically symmetrical to the radial intersection planes of the deflection surfaces or division planes of the Decreases existing sector-shaped areas of lower light intensity are, as experiments show, due to the arrangement and design of the Deflection surfaces sufficiently flooded with light.
- FIG. 1 which serves as an overview, shows one on a partition 1 attached input unit 2, with a housing 3 on one side, an adjusting button 4 on the opposite side of the partition 1 are arranged.
- a connector base is designated, which, as from FIG. 3 shows a circuit board 6 held in the housing 3 connected is.
- the latter carries a rotary switch or a rotary and axial actuable switch 7, means for power supply and Signal processing and light-emitting diodes, two of which in FIG. 3 are shown and designated 8 and 9.
- One of the rotary switch 7 assigned, partially D-profiled control shaft on which the control knob 4 is attached, is designated 10. 11 provides a cable 12 final and in the connector socket 5 is the connector.
- the control knob 4 is, as can be seen from the drawings, stepped shaped, on the annular step face 13 one, for example the Switching steps of the rotary switch 7 corresponding division 14 is formed is.
- the dividing elements, one of which is denoted by 15, are at the selected embodiment punctiform and by means of transmitted light designed to be illuminated.
- the control knob 4 is expediently used in the two-component injection molding process manufactured, that is, the knob 4 consists of a relatively hard, light-conducting material made of PMMA Carrier 16 and a relatively soft, made of TPE, Easy-to-grip and opaque coat 17.
- the carrier 16 On the carrier 16 are a version 18 for connecting the control knob 4 with the Actuating shaft 10 and the number of pins corresponding pins 19, the end faces of which are the dividing elements 15. Accordingly, the jacket 17, which is in a suitable manner with the Carrier 16 is positively toothed, designed such that the End faces of the pin 19 are uncovered.
- a light guide is designated, which is indirectly by attaching the Housing 3, which with a threaded approach 21 through the partition 1 reaches through, is held on the partition 1.
- the housing 3 is fastened by means of a nut 22, which a spring washer 23 is assigned.
- the housing 3 is composed of two housing components is, the parting plane axially intersects the thread projection 21 and on the ledge halves strips and associated recesses as Joining elements are formed.
- One of the strips is shown in Figure 3 and designated 24.
- the two housing components by means of bayonet and locking connection means are put together, because they are not essential to the invention, in detail are not designated.
- the light guide 20, which, like the support 16 of the adjusting button 4, is made of PMMA is made up essentially of one with a conical Shell surface 27 provided, flat ring 28 on which as Extensions 29, 30 and 31 serving as light guide channels are formed.
- the End faces or the light entry surfaces of the extensions 29, 30, 31 of one of which is denoted by 32 in FIG. 4 can be used for focusing the light also be convex, are polished to avoid light loss.
- With the same surface quality are the redirecting, as Light-conducting surface effective surface area 27 and in depressions 33, 34 and 35 equipped deflection surfaces 36, 37, 38, 39, 40 and 41 equipped, the depressions 33, 34 and 35 in the extension of the extensions 29, 30, 31 formed on the opposite side of the light guide 20 are.
- the deflecting surfaces are curved in a suitable manner individual depressions 33, 34 and 35 are not concentric with the lateral surface 27 but formed such that they are each in a radial plane of the Cut the light guide 20.
- An unspecified annular, the Knob 4 facing light exit surface of the light guide 20 is roughened to be uniform by light scattering To achieve illumination of the division 14.
- the Threaded projection 21 of the housing 3 corresponding opening in the light guide 20th designated.
- Reference numerals 43 and 44 denote two of those for the Passage of the extensions 29, 30, 31 in the housing 3 required Holes.
- FIG. 5 shows that one of the fastening of the Input assembly on the partition 1 serving through opening 45 on the one hand a socket 46 assigned to the threaded connector 21 on the other hand for the passage of the extensions 29, 30, 31 of the light guide 20 provided bulges 47, 48 and 49.
- the arrow indicated symbolizes the direction of light between a light emitting diode 8 and a dividing element 15 of the adjusting knob 4.
