Description

Die Erfindung betrifft eine Bedientastatur, insbesondere für eine Kraftfahrzeug-Klimaanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a control keyboard, in particular for a motor vehicle air conditioning system according to the preamble of claim 1.

Eine solche Bedientastatur ist beispielsweise aus der DE 43 44 054 C2 bekannt, wobei diese eine erhebliche Bautiefe aufweist, die bei einigen Anwendungen stört. Darüber hinaus besteht Bedarf nach einer Ausführung einer Bedientastatur, bei der ein Zusammenbau der Einzelteile ohne weitere Verbindungselemente wie Schrauben, Nieten usw. erfolgen kann.Such an operating keyboard is known for example from DE 43 44 054 C2, whereby this has a considerable depth, which is annoying in some applications. There is also Need for a design of a control keyboard, in which an assembly of the individual parts can be done without further connecting elements such as screws, rivets, etc.

Es ist daher Aufgabe der Erfindung, eine gattungsgemäße Bedientastatur derart zu gestalten, daß eine geringe Bautiefe und einfache Montage der Einzelteile ohne Verwendung von Verbindungselementen erreichbar ist.It is therefore an object of the invention to design a generic control keyboard in such a way that that a small depth and easy assembly of the individual parts without using Fasteners can be reached.

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst worden.

  • Fig. 1 zeigt eine Draufsicht und Fig. 2 eine Seitenansicht einer Bedientastatur 1, insbesondere für eine Kraftfahrzeug-Klimaanlage, die frontseitig in ein Armaturenbrett 2 einbaubar ist, bestehend aus einem Gehäuse 3, in dem elektrische und elektronische Bauteile angeordnet sind, wobei mehrere Tasten 4 der Tastatur auf Schalter 5 (Fig. 9) einwirken, die auf einer Leiterplatte 6 (Fig. 9) angeordnet sind.Fig. 1 shows a plan view and Fig. 2 shows a side view of a control keyboard 1, in particular for a motor vehicle air conditioning system that can be installed on the front in a dashboard 2, consisting of a housing 3, in which electrical and electronic components are arranged are, with several keys 4 of the keyboard on switch 5 (Fig. 9) act on a Printed circuit board 6 (Fig. 9) are arranged.

    Es ist vorgesehen, daß die Tasten 4, in Fig. 5 und 6 dargestellt, von der Bedienseite her mit Führungsansätzen 7 auf Führungsstempel 10 aufgeschoben und innerhalb einer Verrastung 11 gehalten sind, die eine Verstellung der Taste 4 innerhalb zweier Anschläge 12, 13 begrenzt, wobei der von der Taste 4 betätigte Schalter 5 innerhalb der Verstellung ein- und ausschaltet.It is envisaged that the keys 4, shown in Fig. 5 and 6, from the operating side Guide lugs 7 pushed onto guide stamp 10 and within a latch 11 are held, which limits an adjustment of the key 4 within two stops 12, 13, the switch 5 actuated by the button 4 on and within the adjustment turns off.

    Es ist vorteilhaft, wenn Führungsstempel 10 und Tastenführungsansatz 7 eine Schwalbenschwanzführung 14 bilden (Fig. 13), die durch Ausnehmungen 15, 16 der Leiterplatte 6 und einer Trägerplatte 17 hindurchragt (Fig. 9). Diese Maßnahme ermöglicht die Anordnung der Leiterplatte 6 sehr dicht an den Tasten 4, wobei der sogenannte Schubladeneffekt, d. h. Kippen der Tasten 4, nicht auftreten kann. It is advantageous if the guide stamp 10 and the key guide attachment 7 have a dovetail guide 14 form (Fig. 13) which through recesses 15, 16 of the circuit board 6 and a support plate 17 protrudes (Fig. 9). This measure enables the arrangement of the Circuit board 6 very close to the buttons 4, the so-called drawer effect, d. H. Tilting the 4 keys, can not occur.

    Die Verrastung 11 ist durch einen Sperransatz 20 auf dem Führungsstempel 10 und eine Ausnehmung 21 in dem Führungsansatz 7 gebildet, wie aus Fig. 9 erkennbar ist, wobei der Sperransatz 20 unter elastischer Verformung der Führungsansatzwandung in die Ausnehmung 21 einrastet. Hierdurch entfallen Verbindungs- bzw. Sicherungselemente.The locking 11 is by a locking projection 20 on the guide stamp 10 and one Recess 21 formed in the guide lug 7, as can be seen from Fig. 9, the Locking lug 20 with elastic deformation of the guide lug wall into the recess 21 snaps into place. This eliminates connecting and securing elements.

    Dadurch, daß mit dem Schalter 5 kontaktierende Tastenflächen 22 der Tasten 4 in einem Tastenrahmen 23 bestehen, ergibt sich ebenfalls eine flache Bauweise, wobei der Tastenrahmen 23 die Taste 4 selbst gegen Verformung sichert (Fig. 5 und 6).Characterized in that with the switch 5 contacting key surfaces 22 of the keys 4 in one Key frame 23 exist, there is also a flat design, the key frame 23 secures the button 4 itself against deformation (Fig. 5 and 6).

    Es ist vorgesehen, daß die frontseitig sichtbaren Tastenflächenwände 24 den Tastenrahmen 23 überragen (Fig. 5 und 6) und in Tastenführungsausnehmungen 25 einer Gehäusefrontwandung 26 geführt sind (Fig. 4). Hierdurch ist ein gefälliges Aussehen erreicht worden und ein Lichtausfall von nicht dargestellten Leuchtelementen aus dem Inneren der Bedientastatur 1 verhindert.It is envisaged that the key surface walls 24 visible on the front face the key frame 23 protrude (Fig. 5 and 6) and in key guide recesses 25 of a front wall of the housing 26 are guided (Fig. 4). As a result, a pleasing appearance has been achieved and a light failure of lighting elements, not shown, from the inside of the control keyboard 1 prevented.

    Es ist vorteilhaft, wenn die Leiterplatte 6 von der Trägerplatte 17 getragen wird, die mit Klippsansätzen 27 in einen Gehäuserahmen 30 eingesetzt und in Klippsschlitzen 31 des Gehäuserahmens 30 gehalten ist (Fig. 3). Hierdurch ist eine wirtschaftliche Montage der Bedientastatur 1 erreicht worden (Fig. 9).It is advantageous if the circuit board 6 is carried by the carrier plate 17, which with Clip approaches 27 inserted into a housing frame 30 and 31 in clip slots Housing frame 30 is held (Fig. 3). This is an economical assembly of the Control keyboard 1 has been reached (Fig. 9).

    Zur Anzeige der gewünschten, eingestellten Regeldaten weist die Bedientastatur 1 eine bekannte LCD-Anzeige auf (Fig. 10), wobei die Trägerplatte 17 mit umgebogenen Greifansätzen 32 ein LCD-Element 33 hält, das über verspannte Leitgummistücke 34 mit Leitern der Leiterplatte 3 kontaktiert ist. Durch die verspannten Leitgummistücke 34 ist eine dauerelastische Halterung des LCD-Elements 33 erreicht worden.To display the desired, set control data, the control keyboard 1 has a known one LCD display on (Fig. 10), the support plate 17 with bent gripping lugs 32 holds an LCD element 33, which is clamped over conductors 34 with conductors of the PCB 3 is contacted. Due to the tensioned conductive rubber pieces 34 is permanently elastic Holder of the LCD element 33 has been reached.

    Für eine einfache Montage der Bedientastatur 1 in eine Öffnung des Armaturenbretts 2 ist vorgesehen, daß die Trägerplatte 17 einen den Gehäuserahmen 30 umgreifenden Federansatz 35 aufweist (Fig. 7 und 8), der in das Armaturenbrett 2 bei eingesetzter Bedientastatur 1 durch die Armaturenbrettwandung eingefedert ist und diese Armaturenbrettwandung mit einer komplementären Hakenausbildung 36 umklammert, wobei die entgegengesetzte andere Seite des Gehäuserahmens 30 (Fig. 2) mit einem Steckeraufnahmeteil 37 und der Gehäusefrontwandung 26 eine Aufnahmenut 38 für die Armaturenbrettwandung bildet. Somit braucht die Bedientastatur 1 nur mit der Aufnahmenut 38 in die Öffnung des Armaturenbretts 2 bzw. über die Armaturenbrettwandung gesteckt und mit der anderen Seite in die Öffnung eingedrückt zu werden, so daß der Federansatz 35 einfedert und die Armaturenbrettwandung mit der Hakenausbildung 36 umklammert. Damit ist eine einfache Befestigung der Bedientastatur erreicht.For easy assembly of the control keyboard 1 in an opening of the dashboard 2 is provided that the support plate 17 has a spring extension encompassing the housing frame 30 35 has (Fig. 7 and 8) in the dashboard 2 with the control keyboard inserted 1 is compressed by the dashboard wall and this dashboard wall clasped with a complementary hook formation 36, the opposite other side of the housing frame 30 (Fig. 2) with a connector receptacle 37 and the Housing front wall 26 forms a receiving groove 38 for the dashboard wall. Thus, the control keyboard 1 needs only with the receiving groove 38 in the opening of the dashboard 2 or inserted over the dashboard wall and with the other side in the Opening to be pressed in so that the spring extension 35 compresses and the dashboard wall clasped with the hook formation 36. This makes it easy to attach reached on the control keyboard.

    Wie in Fig. 9 bis 11 dargestellt, die Querschnitte der Bedientastatur 1 zeigen, ist vorgesehen, daß die umgebogenen Greifansätze 32 an beiderseits der Trägerplatte 17 angebogene Winkelansätze 40 bestehen, wobei Ausnehmungen 41 im Biegebereich 42 (Fig. 7 und 8) so angeordnet sind, daß Schenkelansätze 43, 44 oberhalb und unterhalb des Biegebereichs 42 bestehen, so daß die Schenkelansätze 43, 44 die Winkelansätze 40 gegenüber den Gehäuserahmenwänden 45 parallel ausrichten können.As shown in FIGS. 9 to 11, which show cross sections of the control keyboard 1, it is provided that that the bent gripping lugs 32 are bent on both sides of the carrier plate 17 Angular approaches 40 exist, with recesses 41 in the bending area 42 (FIGS. 7 and 8) are arranged that leg extensions 43, 44 above and below the bending area 42nd exist, so that the leg extensions 43, 44, the angle extensions 40 relative to the housing frame walls 45 can align in parallel.

    Zusätzlich zu diesen Maßnahmen kann die Trägerplatte 17 in den Ausnehmungen 16, durch welche die Führungsstempel 10 hindurchragen, angebogene Arretierflächen 46 aufweisen, an denen sich die Leiterplatte 17 maßgenau abstützen kann.In addition to these measures, the carrier plate 17 can be made in the recesses 16 which protrude through the guide punches 10, have bent locking surfaces 46, on which the circuit board 17 can be supported dimensionally.

    Fig. 12 zeigt eine Ausschnittsvergrößerung aus Fig. 11, aus der ersichtlich ist, wie der Klippansatz 27 der Trägerplatte 17 in den Klippschlitz 31 eingerastet hat, und ebenso wie die Schenkelansätze 43 und 44 die Winkelansätze 40 gegenüber den Gehäuserahmenwänden 45 parallel ausrichten.FIG. 12 shows an enlarged detail from FIG. 11, from which it can be seen how the Clip approach 27 of the support plate 17 has snapped into the clip slot 31, and just like that Leg approaches 43 and 44, the angle approaches 40 with respect to the housing frame walls Align 45 parallel.
