Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides at least one sliding member (
4), the operation knob (5) of the sliding member (4) protrudes from the base body (2), and the transmission device (6-El, 10.12
) on a control element, for example for regulating a heating, air-conditioning and/or ventilation system of a motor vehicle.

Operating units of the above type, which are housed in the instrument panel of a motor vehicle, are in particular variously named 1, e.g. as a motor vehicle air conditioner.
．． It is used to open distribution flaps to various extents for the delivery of cold or warm air in devices that are used for heating and cooling. In this case, the operation usually takes place via a Bowden wire.

A Bowden wire is also provided in the operating unit described in German Patent Application No. 31 25 093. The operating unit consists of an elongated basic body in which a sliding member is movable between two end positions in a channel cut out therein. The slide member is guided within the channel by rollers attached to the slide member.

These rollers abut against the channel walls. The sliding member has an operating knob and an adjustment arm that protrude from the base body and are configured to protrude in various directions. This adjustment arm is used to manipulate the Bowden wire. However, this adjusting arm also serves as a switching element which supports a contact bridge, the contact bridge of which cooperates with a fixed contact on the basic body and acts as a sliding switch.

Other operating units for first-class air blowers and ventilation blowers of motor vehicles are registered under Utility Model No. 83 of the Federal Republic of Germany.
12000. A part of the steering wheel projects from the instrument panel, and the steering wheel is supported in a U-turning manner within the basic body. A pinion is formed on the steering wheel. The teeth of this binion engage the teeth of the gear.

This gear engages the rack. This rack is held movable in the longitudinal direction within the guide of the basic body. As the rack is moved to various locking positions, a cam on the rack sequentially operates a plurality of adjacent contacts. In this way, the blower motor is switched on or off in stages. A display device is connected to the rack and can be viewed from outside through a transparent area of the instrument panel.

Since the sliding member of the operating unit for heating and ventilation inside the vehicle passes through the slit, the internal structure is likely to become contaminated. Operation unit (for lighting)
- There are many cases where light leaks to the outside through. In order to prevent this, the Federal Republic of Germany Patent Application Publication No. 3211
In No. 319, this slit is covered with tape, and this tape is attached to the sliding member. This tape can be left open at the ends or used as a dress tape. The tape itself is guided in the cutout between the basic body and the border cover on both sides of the slit.

Another type of operating unit for illuminating an operating knob is described in DE 32 06 288 A1. Here, one or more sliding members are provided, which are guided in slots in the basic body. A sliding member operates an adjustment lever via an intermediate lever, to which a Bowden wire is commanded. The operating knob, which is attached to the sliding member on the outside, is illuminated by a movable light guide. The light guide emerges from the illumination source and is guided through the center of the sliding member to the operating knob.

In the operating unit described in Federal Republic of Germany Patent Application Publication No. 1580098, the individual operating positions f of the sliding members are
It is displayed by flash lighting.

These sliding members are guided in slits in the basic body. The yarn projecting from the other slit transmits the adjusting movement of the sliding member to the adjusting member via the lever bar. These adjustment members are Bodenweyerke adjustable. The entire surface of the substrate is provided with light strips. These light strips extend over the entire adjustment path of the individual slide members. Viewed from the outside, these light strips can be perceived as light tapes. Illumination of the individual light strips takes place via a frame part made of transparent plastic.

Is this frame part a light beam? Focus it and send it to the light guide. In order to be able to clearly identify both the starting and ending positions of the sliding member, the light strip is wedge-shaped at its front end face. It is also possible to provide color lighting. However, it is not clear from the above-mentioned public notice how this will be realized.

Another operating unit for automobiles in which an operating knob of a sliding member is illuminated is disclosed in Utility Model No. 76349 registered in the Federal Republic of Germany.
It is known from No. 78. The sliding member is guided within the groove of the base body.

The light necessary for illuminating the operating knob reaches the operating knob after polarization from a central light source via a light guide arm or a light guide. At the light transition surface, the light guide is grooved, so that a scattering surface is formed. The light guide is manufactured by polymethacrylate t-injection molding. A central light source is inserted into a hole in the block, from which a light guide emerges. As a light source, a luminescent diode is used, which can emit not only white but also colored light.

A light guide rod for color illumination of NI devices in motor vehicles is described in German Utility Model No. 8004562. The reflective surface of the light guide rod has
A single layer of collar 30μ thick is applied. On top of this color layer is a second white layer. A unique light guide rod is required for each color. However, this proposed 2
It is not possible to generate two different colored planes.

The object of the present invention is to reduce the width, provide a perfect linear guide for the sliding member with low friction, and reduce the speed. At the same time, by using a single light source, the operating position of the operating mechanism can be easily and easily determined. The display can be illuminated in multiple colors so that it can be clearly observed even in the dark without glare, reducing the risk of contamination of the internal structure, and preventing or reducing leakage of external light and motor noise from the slit. The object of the present invention is to provide an operating unit of the type described at the beginning, which is lightweight and has a simple structure.

According to the present invention, this problem is solved as follows.

That is, the transmission device is constituted by a reduction transmission device having a first rack formed in a two-sliding structure and whose position is variable, and a second rack formed integrally and whose position is fixed, and between the two racks. - at least one gear t in operative connection with both racks;
It is rotatably and movably supported, and the gears are connected.

Further advantageous embodiments of the invention emerge from the dependent claims.

Next, the present invention will be explained in detail with reference to the drawings based on examples.

FIG. 2 is a schematic perspective view showing a part of the operating unit cut away and enlarged. , FIG. 3 is a schematic perspective view of a sliding member having a brake spring portion. FIG. 4 is a schematic perspective rear view showing the light emitting center in an exploded manner. FIG. 5 is a schematic perspective view of a light guide section made up of a plurality of single light guides, with the rear side facing down.

Is Fig. 6 another light guide part? 6 is a schematic perspective view similar to FIG. 5. FIG. FIG. 7 is a schematic perspective view of a unitary light guide section.

FIG. 8 is a schematic perspective view of another single configuration light guide section. @
FIG. 9 is a schematic perspective view of another single-piece light guide section.

FIG. 1 shows, for example, a heater, air conditioner and/or ventilation system 1Itl! in a car! An operating unit such as that which may be used for l-adjustment is illustrated in a perspective diagrammatic view. The embodiment illustrated in FIG. 1 has two sliding members and one pivot knob. By using these sliding members and pivot knobs, the adjustment element is usually operated indirectly.

Such adjustment elements include mechanical components, such as, for example, flaps, and electrical components, such as, for example, electric motors. Is the indirect operation of mechanical adjustment elements 2 ranks, rope drives, Bowden wires, etc.? It is done through. On the other hand, indirect operation of the electrical adjustment element takes place via potentiometers or switches, etc. operated by pivot knobs or sliders. The height of the voltage drawn from the tap is an indication of the regulating dust.

In FIG. 1, an elongated, U-shaped plastic substrate is designated at 2 in cross section. The reinforced side walls of this base body 2 each have an elongated cutout 9 . A reduction gear of the sliding member 4 is accommodated in each cutout 9 . The sliding member 4 is movable between two end positions relative to the base body 2. The sliding path of the sliding member 4 is limited by a projection 24 formed on the base body 2 as a stopper. It is effective to provide protrusions at both ends of the slideway.

As is clear from FIG. 3, the sliding member 4.

It consists of a U-shaped slider having a slider bottom 14. Two holding members 15 are formed on one side of the slider bottom at right angles to the slider bottom. ing. These holding members 15 are integrally connected to the slider bottom via a narrow bridge 43 on the end face side of the slider bottom. With this type of connection, the holding member 1
5 is configured to be elastic. Individual retaining members 15 are attached to the coil.
This is due to the presence of the tongue portion 16 in the free cap. The tongue portions 11 and 16 have the function of holding and guiding the sliding member by sliding it onto the base body after locking. In this case, this guidance takes place in such a way that the tongue 16 engages behind the web 17, which extends like a rim at the bottom or back side (+!II) of the base body.

As is clear from FIG. 3, on the other side of the slider bottom, a first rack 6 constitutes a leg extending at right angles. This first rack has internal teeth. A brake spring 19 is inserted into the recess 44 on the outside of the first rack 6 .

This brake spring 19 is supported under the action of a piezoelectric spring on the one hand on one wall of the recess 9 of the basic body 2 and on the other hand on the slide 4 itself. With this pie scan, a desired sliding process of the sliding member can be selected in advance within a predetermined range.

An angle piece 18 is formed on the extension of the slider bottom 14 and is aligned with the slider bottom 14 . Angle piece isH, operating knob 5 at its bent free end
is supported.

This operating knob 5 is connected to the slider bottom 14 and thus to the part of the angle piece 18 that is flush with the slider bottom 14 and passes through the slit formed between the basic body 2 and the border frame 3.

Located off to the side. As a result, a type of labrinth seal is formed. In this way, you can protect the inside from dirt to some extent and you will be able to do 7.

Additionally, mechanical and electrical protection can be provided by preventing elongated objects from entering the interior through the slits. In addition, if the back of the operating unit is sealed with a cover, motor noise can be attenuated or significantly reduced.

A linear drive with a reduction gear is provided in the lateral cutout 9 of the base body 2 . This linear drive device includes, for example, a first rack 6 of the sliding member 4 and a second rack 7 formed on the lower wall of the notch 9 of the base body 2, as is clear from FIG. It is configured. In the embodiment shown, three gear wheels 8 are rotatably mounted between the two racks. It is also possible to consider embodiments in which four or more gears are provided. These gears 8 are attached to journals 13. However, gear 8q can be rotated. The journal 13 is attached to a rod 10, which is inserted into the groove 1 at the bottom of the notch 9.
Guided within 1. As is clear from FIG. 2, the journal 13 is perpendicular to the sliding direction of the rod 10.

When the sliding member moves, the gear 8 rotates. The teeth of the gear 8 engage not only the teeth of the first rack 6 but also the teeth of the second rack 7. The rod 10 also moves together with these gears. Due to this reduction gearing, the sliding path of the rod is half the size of the sliding path of the sliding member. Therefore, the first rack 6
is slightly longer than half of the sliding path of the sliding portion 4. In order to achieve a reliable sliding process, it is advantageous to use at least three gear wheels.

In this way, only two gears engage with both racks at each of the starting and ending ends of the sliding path of the sliding member near the stone. In the center of the sliding path of the sliding member, the first rack 6.

It will run through all three gears.

As can be seen in FIGS. 1 and 2, the Bowden wires 12 are connected to the individual rods 10. If you use this Bowden wire 12ft:.

Mechanical adjustment elements, not shown, can be adjusted. In addition to this mechanical transmission of forces, electrical connections can also be provided. However, such an embodiment is not illustrated. To configure such an embodiment, K is
Slit in groove 11)? establish. A driver, additionally formed or attached in some way to the rod 10, passes through this slit, with which the spring support of the potentiometer can be adjusted.

The voltage drawn from the sliding spring of the spring support is.

Via an electrical connection, an electrical regulating element (e.g. electric motor) K
transmitted.

In the embodiment shown in FIG. 1, there are two methods of sliding adjustment and one method of pivoting adjustment. In this case, the base body 2 has a peripheral edge where the slits for the side and sliding members are located;
It is covered by an edging frame 3. When three or more sliding adjustment methods are used as eight slides, a plurality of base bodies can be arranged as necessary and covered by a common border frame. However, the slit provided must be covered and protected by the edging seam cloth.

As apparent from FIG. 1, one method of pivoting and adjustment is provided by pivot knob 26. For this purpose, the base body 2t is supplemented with an extension 25 on its narrow side, which is attached to either the border frame 3 or the base body 2 or is connected integrally with the border frame 3 or the base body 2. This additional portion 25 is configured in the shape of a science and engineering square. However, the width of the additional portion 25 corresponds to the width of the base body 20 having the border frame 3.

Analogous to the case with the sliding member 4, the pivot knob 26 allows one to operate a mechanical adjustment element, for example via a rack, or an electrical adjustment element via a potentiometer. The embodiment illustrated in FIG. 4 shows a first solution using mechanical adjustment elements.

Solutions are also possible in which the thermal rack displaces the spring support of the potentiometer.

In order to be able to clearly see not only the position of the pivot knob 26 but also the position of the sliding member, especially in the dark, the operating unit has an illuminated display, as is clear from FIG. .

Both displays are composed of a flj light emitting center 20, and light guides are led out from the light emitting center 20 on two surfaces. Light guide 29 on the first lower side! l They are arranged in a star shape with respect to the luminescent center. Therefore, the end 31 of the light guide 29 forms an arc, which can be seen on the front side of the extension 25 at the end 31ij of the light guide 29, as is clear from FIG. Since the ends 31 of the light guide 29 are located adjacent to each other, a luminescent band display similar to a thermometer scale is provided. In order to be able to better identify the position of the pivot knob, the end 31 of the light guide 29 can also be colored and illuminated.

When the 26ft turning knob is used for a heating/cooling cabinet, for example, the W/red color display is used. However, in this case, the color display is for all ends 31 at one end position of the pivot knob.
It would be a problem if it were to emit light only in red, and the other end position should be made to emit light only in blue.

One light emitting center 2o is located on the back side of the additional portion 25. A circular first part 32 made of plastic is attached to the extension 25 on the rear side. first part 3
2 is provided with a radially extending cutout 45 which accommodates the light guide 29 of the first side. Furthermore, a central notch 34 is provided at the center.

A revolving body 35 is rotatably supported within the central notch 34 . This revolving body 35 is configured like a hollow cylindrical shaft, and this shaft is connected to the additional portion 25? It penetrates through and is prevented from moving in the axial direction by an elastic face washer 46 on the front side.

A hole 47 is provided in the center of the pivot knob.

It extends into the JL47tl grip piece and is closed on the front side of the grip piece by a window 48 constructed of transparent material. A notch 49 extends radially from the hole 47 . A mounting portion 50 is inserted into the hole 47 and the notch 49. The mounting portion 50 is constructed from a light guide material. As is clear from FIG. 4, this mounting portion 5o is bent many times and has a bezel for deflecting the light beam.

The rotation of the rotating body 35 by the swiveling knob 26 takes place in such a way that the rotating body 35 has two diagonally located openings 51 in the end face (11!l), in which case on one side the mounting part 5
0 enters one of the openings, and on the side opposite this) an additionally formed entrainer, not shown, which enters the hole 47 enters the other opening. In order to attach the rotation knob to the revolving body, do you need a driver and an opening part? , snap-in effect? It can be configured such that a snug fit occurs.

In the immediate vicinity of the pivoting knob, on the rear side of the attachment part 25, a guide strip 40 (5) is formed, for accommodating a third rack 39 movable in the guide chamber. has a guiding chamber passing through it.In one direction j, a third
The rack has teeth that engage the teeth of the pinion 38 through cutouts in the guide chamber.

When the rotating body is rotated by the pivot knob, the third rack moves and can operate the mechanical adjustment element or the sliding potentiometer or the sliding switch via the Bowden wire. These mechanical adjustment elements or sliding potentiometers or sliding switches actuate electrical adjustment elements in an electrical manner. At least the portion of the rotating body 35 that enters the first portion 32 is made of a transparent material.

A color tape 37 is guided between the portion of the rotating body 350 that enters the first portion 32 and the wall of the central cutout 34, and is attached to the rotating body. One color tape is colored red, and the other one is colored blue. The two colored tapes are longer than the guide body inlets 36 distributed on the circumference. It is effective to make the two color tapes longer than the inner diameter of the central notch 34. In order to avoid incorrect colors due to overlapping color tapes, the first
An outlet opening 28 is provided in the portion 32 of the . When the pivot knob is in place, any unneeded protruding colored tape portions will pop out of these exit openings 28.

The color tape is placed within the guide body 52 to avoid damage to the color tape. Depending on the position of the pivot knob, a part of the end 31 of the light guide 29 will emit red light and another part will emit blue light. In this way, it is possible to easily identify that the vehicle is set to heating and ventilating with outside air. Since in the end stop position all ends of the light guide must emit a single color, the individual color tapes must be distributed over the circumference and longer than the guide inlet 36.

The light guide 29 of the first part 32 of the luminescent center 20 is carved to transmit colored light, while the light guide 30 transmits only white light. These light guides 30 are arranged on the second side,
It is held within the second portion 33 of the luminescent center 20 .

The second part 33 is connected to the first part, for example by a snap connection. A hole 53 is provided in the center of the second part 33, into which the lamp socket 54 is inserted together with the light source 27. This light source penetrates not only into the first part but also into the second part. Embodiments are also conceivable in which the lamp socket is constructed integrally with the second part.

The light guide 30 arranged in a substantially circular shape protrudes from the second portion 33 on the m20 plane and the light guide part 21 located on one plane.
will be guided to. The light guide portion 21 is located on the front side of the base body 2. In the embodiment illustrated in FIGS. 5 and 6, this light guide section 21 is composed of a single light guide 41. In the embodiment shown in FIGS. These single light guides 411C require surface illumination in order to be able to clearly identify the respective position of the sliding member. For area illumination, one of the two implementation methods shown in FIGS. 5 and 6 can be selected. 5 and 6 show the single light guide 41 with its back side down, i.e. in the assembled condition, the ridges 22 or notches 42 are on the bottom side, i.e. on the surface of the base body 2. Position so that they face each other.

The ridges and notches polarize the light and guide it towards the smooth surface. As can be seen from FIG. 1, the ridges or notches do not extend over the entire length of a single light guide. It is important to illuminate the entire plane as uniformly as possible. Since the light guide 29,50 and the single light guide 41 are manufactured by injection molding, the embodiment of FIG. 5 is somewhat difficult to manufacture due to tooling technology. Therefore, the embodiment of FIG. 6 is superior. For this purpose, in the tool, a recess is formed in the injection molding tool, similar to the ridge 22 of the single light guide 41. The surfaces of the recesses, unlike the ridges, can be ground very smooth.

In this way, it is also possible to form a smooth surface for the raised portion 22 using a relatively simple method. This smooth surface is extremely important for light polarization or light scattering. Because it is pre-guided by the light guide 30, the light beam is not incident parallel to the surface, so that the light beam is deflected onto the smooth surface by the ridges 22 and becomes polarized. In this way, only a relatively small proportion of the light beam hitting the ridge is split, so that the radiation across the single light pipe is relatively good and uniform.

In the illustrated embodiment, a plurality of single light guides are provided in close contact with one another. It is also conceivable to use thermal conductor plates. FIGS. 7 to 9 show three embodiments of light guide plates 55 to 57 of single unit construction. These embodiments are shown on their backs as in FIGS. 5 and 6.

In the embodiment of FIG. 7, a plurality of parallel grooves 58 are cut out in the light guide plate 55. In the embodiment shown in FIG.

These grooves separate the light guides 59 from each other. As already explained in conjunction with FIG. 6, the elevation 601i is provided for reasons of tool technology for light polarization or light scattering. At the end of the basic body, the light guide 59 is curved and is guided from there to the luminous center.

Another embodiment of a unitary light guide plate 56 is shown in FIG. Again, a plurality of grooves 61 ft are provided, which grooves 61 can be configured to be curved in contrast to the grooves of FIG.

In this way, the light guides 62 can be formed in communication with each other. In this way, optimum utilization of the light is ensured. At approximately the center of FIG. 8 is a straight light guide 63.
is extended, and the light guide 63l-j has a full length of 64
separated by. This light guide 63 is used, for example, to additionally illuminate a switch (not shown). A raised portion 65 is also provided in this embodiment, and the extent of the raised portion 65 corresponds to the illumination surface. In FIG. 8, it is necessary to illuminate a relatively large area as uniformly as possible. It is also possible to illuminate relatively small surfaces and symbols, such as circles and triangles. For this purpose, it is only necessary to set the shape to correspond to the surface layout of the raised portion.

Possible shapes are clear from FIG. This light guide plate 57 also has a plurality of grooves 661, and various light guides 67 are formed by these grooves 66. light guide 6
7#'i, the surfaces to be illuminated 6B, 69 are guided, in which case all light guides are utilized as much as possible. In this embodiment, the light guide also has a raised area 70 at the point or area to be illuminated.

For example, as is clear from FIG. 2, four ribs 231fr are provided on the front side of the base body 2, and the recess 23 accommodates the light guide portion. In this way, the light guide portion can be well protected. Furthermore, if required, the light guide part can be easily removed with a foil with an explanation and/or symbol. Plexiglas (polymethyl methacrylate) is usually used as the transparent material for the light guide.

The limit of shape stability of this material is approximately 90° to 100°C. Since relatively high temperatures can be reached in automobiles, it is desirable to use materials with a relatively wide range of use and good light conductivity. The material that satisfies these requirements is polycarbonate ester (product name Nimacrolon).
There is. Shape stability is 140° to 150°C. The range of use where high strength, rigidity, hardness and viscosity are recognized is -
150' to +135°C.

The refractive index is 1.56-1.65, which is extremely high compared to transparent plastics.
