Description

Elektronisches Gerät Electronic device
Die Erfindung betrifft ein elektronisches Gerät mit einem Displayträger, an dem ein Display angeordnet ist, wobei der Displayträger auf seiner Außenseite mit einer Schicht versehen ist, die aus einem transparenten gießfähigen Polymermaterial besteht. The invention relates to an electronic device with a display support on which a display is arranged, the display support being provided on its outside with a layer consisting of a transparent castable polymer material.
Das Interieur in modernen Fahrzeugen erhält zunehmend Displayapplikationen. Hinzu kommt der Wunsch diese Displays hinter geschlossenen Oberflächen zu montieren. Derzeit werden Bauteile in Einoder Zweikomponentenspritzgusstechnik erzeugt, die einen transparenten Teilbereich haben oder eine vollflächige transparente Schicht hinter einem eingefärbten Bauteil mit einem Fenster aufweisen. Anstatt eines eingefärbten Bauteils kann auch eine dekorative Folie hinterspritzt werden. Hierbei kann das Fenster durch einen Druck auf der Folie realisiert sein. The interior of modern vehicles is increasingly being fitted with display applications. There is also the desire to mount these displays behind closed surfaces. Components are currently being produced using one-component or two-component injection molding technology, which have a transparent partial area or have a full-surface transparent layer behind a colored component with a window. Instead of a colored component, a decorative foil can also be back-injected. In this case, the window can be realized by printing on the film.
Solche Bauteile enthalten im Allgemeinen mechanische Spannungen, die sich mechanisch oder auch optisch auf die Applikation eines Displays auswirken. Diese Spannungen kann man durch die Wahl bestimmter Kunststoffe und bestimmter Prozesse zwar minimieren, aber nicht vollständig beseitigen. Such components generally contain mechanical stresses that have a mechanical or optical effect on the application of a display. These tensions can be minimized by choosing certain plastics and certain processes, but they cannot be completely eliminated.
Ein gattungsgemäßes elektronisches Gerät ist aus der deutschen Gebrauchsmusterschrift DE 20 2015 002 460 111 bekannt. Dieses Dokument beschreibt ein elektronisches Gerät, bei dem die äußere Seite eines Gehäuseelements mit einem Polymermaterial beschichtet ist. Eine Elektronik ist dagegen auf der Innenseite des Gehäuseelements angeordnet. Dieses ist nachteilig, wenn zu der Elektronik ein Display gehört, dessen Darstellungen von der Außenseite des Gehäuseelements aus erkennbar sein sollen. Es stellte sich die Aufgabe, ein elektronisches Gerät zu schaffen, welches die vorgenannten Nachteile vermeidet. A generic electronic device is known from the German utility model DE 20 2015 002 460 111. This document describes an electronic device in which the outer side of a housing element is coated with a polymeric material. Electronics, on the other hand, are arranged on the inside of the housing element. This is disadvantageous if the electronics include a display whose representations should be visible from the outside of the housing element. The object was to create an electronic device that avoids the aforementioned disadvantages.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Displayträger eine Blendenöffnung aufweist, innerhalb oder unterhalb der das Display angeordnet ist, und dass die Außenseite des Displayträgers und die Blendenöffnung mit dem gießfähigen Polymermaterial überflutet oder überspritzt ist. This object is achieved according to the invention in that the display support has a screen opening, inside or below which the display is arranged, and that the outside of the display support and the screen opening is flooded or overmolded with the castable polymer material.
Der Displayträger weist so eine durchgehende, einheitlich erscheinende Außenseite aus einem Polymermaterial auf, wobei die Darstellungsseite des Displays im direkten Kontakt oder unter Verwendung eines optischen Klebers oder Koppelmittels unterhalb des Polymermaterials angeordnet ist, so dass das Material des Displayträgers keinen Einfluss auf die Darstellungen des Displays hat. The display carrier thus has a continuous, uniform-appearing outer side made of a polymer material, with the display side of the display being arranged in direct contact or using an optical adhesive or coupling agent below the polymer material, so that the material of the display carrier has no influence on the representations of the display Has.
Vorteilhaft ist auch, dass durch den erfindungsgemäßen Aufbau am Displayträger auf ein sogenanntes Coverglas vor dem Display verzichtet werden kann, da das Display durch die finale Überspritzung oder Überflutung mit dem Polymermaterial mit dem Displayträger optisch übergangslos verklebt werden kann. It is also advantageous that the inventive structure on the display carrier means that a so-called cover glass in front of the display can be dispensed with, since the display can be glued to the display carrier without a visual transition by means of the final overmolding or flooding with the polymer material.
Besonders vorteilhaft ist es, als Polymermaterial ein Polyurethan vorzusehen. Nachfolgend sollen mehrerer Ausführungsbeispiele der Erfindung anhand der Zeichnung dargestellt und erläutert werden. Es zeigen It is particularly advantageous to provide a polyurethane as the polymer material. Several exemplary embodiments of the invention are to be illustrated and explained below with reference to the drawing. Show it
Figur 1 ein erstes Ausführungsbeispiel, Figure 1 shows a first embodiment,
Figur 2 ein zweites Ausführungsbeispiel, Figure 2 a second embodiment,
Figur 3 ein drittes Ausführungsbeispiel der Erfindung. Zur Erläuterung des Aufbaus sind in den Figuren jeweils schematisch verschiedene Herstellungsphasen von Ausführungsvarianten des elektronischen Geräts schematisch dargestellt, wobei jede Figur eine zeitliche Abfolge von oben nach unten abbildet. In allen Figuren sind gleichwirkende Teile auch unterschiedlicher Ausführungen jeweils mit den gleichen Bezugszeichen bezeichnet worden. Figure 3 shows a third embodiment of the invention. To explain the structure, different manufacturing phases of embodiment variants of the electronic device are shown schematically in the figures, with each figure depicting a chronological sequence from top to bottom. In all figures, parts that have the same effect, even of different designs, have been designated with the same reference symbols.
Das in der Figur 1 dargestellte erste Ausführungsbeispiel sieht vor, dass in einem ersten Schritt ein Displayträger 1 vorzugsweise durch Spritzgießen hergestellt wird. In dem Displayträger 1 befindet sich eine Blendenöffnung 2, die etwas kleiner ist als das später zu verwendende Display 4. In der Peripherie der Blendenöffnung 2 wird ein Kleber 3 definiert aufgebracht, mit dem das Display 4 mit dem Displayträger 1 verklebt wird. Hierdurch entsteht durch die Blendenöffnung 2 und das angefügte Display 4 am Displayträger 1 eine zur Außenseite 13 des Displayträgers geöffnete Blendenkammer 12. The first exemplary embodiment shown in FIG. 1 provides that, in a first step, a display support 1 is preferably produced by injection molding. In the display support 1 there is a screen opening 2 which is somewhat smaller than the display 4 to be used later. As a result, the aperture 2 and the attached display 4 on the display carrier 1 create an aperture chamber 12 that is open to the outside 13 of the display carrier.
Nachdem dieser Vorgang abgeschlossen ist, wird der Displayträger 1 samt Display 4 in ein Überflutungswerkzeug montiert. Nach dem Schließen des Werkzeugs wird der Displayträger 1 in einer vertikalen Ausrichtung von unten nach oben mit einem Polymermaterial 5 überflutet und ausgehärtet, wodurch auch die Blendenkammer 12 vollständig mit dem Polymermaterial 5 ausgefüllt ist. Es ergibt sich eine geschlossene Fläche zum Nutzer und eine zusätzlicher Schutz sowohl des Display 4 als auch der Außenseite 13 des Displayträgers 1 durch das Polymermaterial 5. Als geeignetes Polymermaterial 5 kann bevorzugt ein Polyurethan eingesetzt werden. After this process is completed, the display carrier 1 together with the display 4 is mounted in a flooding tool. After the mold is closed, the display support 1 is flooded with a polymer material 5 in a vertical orientation from bottom to top and cured, as a result of which the aperture chamber 12 is also completely filled with the polymer material 5 . The result is a closed surface for the user and additional protection of both the display 4 and the outside 13 of the display support 1 by the polymer material 5. A polyurethane can preferably be used as a suitable polymer material 5.
Durch das beim Überflutungsvorgang bereits am Displayträger 1 montierte Display 4 liegt das Polymermaterial 5 nach der Überflutung übergangslos an der Darstellungsfläche 14 des Displays 4 an. Die Figur 2 zeigt ein zweites Ausführungsbeispiel. Diese Variante sieht ebenfalls vor, dass im Displayträger 1 eine fensterartige Blendenöffnung 2 angeordnet ist. Am Rand der Blendenöffnung 2 ist ein Absatz 6 im Displayträger 1 vorgesehen, der derart in die Blendenöffnung 2 hineinragt, dass das Display 4 in die Blendenöffnung 2 eintauchen und sich an Absatz 6 abstützen kann. As a result of the display 4 already being mounted on the display carrier 1 during the flooding process, the polymer material 5 rests seamlessly on the display surface 14 of the display 4 after the flooding. FIG. 2 shows a second exemplary embodiment. This variant also provides that a window-like aperture 2 is arranged in the display support 1 . At the edge of the panel opening 2 , a shoulder 6 is provided in the display support 1 , which protrudes into the panel opening 2 in such a way that the display 4 can dip into the panel opening 2 and be supported on the shoulder 6 .
Die Außenseite 13 des vorbereiteten Displayträgers 1 wird in einem nichtdargestellten Spritzgießwerkzeug überflutet. Geeignet geformte Kerne im Spritzgießwerkzeug bewirken, dass das Polymermaterial 5 nicht oder nur geringfügig tief in die Blendenöffnung 2 eingebracht wird. The outside 13 of the prepared display support 1 is flooded in an injection mold, not shown. Suitably shaped cores in the injection mold ensure that the polymer material 5 is not introduced deep into the aperture 2, or only slightly so.
Im nächsten Schritt wird der Displayträger 1 waagerecht ausgerichtet. Nach dem Aushärten des Polymermaterials 5 wird im Bereich der Blendenöffnung 2 eine optische Klebeflüssigkeit 8 auf die der Blendenöffnung 2 zugewandte Seite des ausgehärteten Polymermaterials 5 aufgetragen. Nachfolgend wird das Display 4 an den Absatz 6 angefügt und mittels der optischen Klebeflüssigkeit 8 mit dem Polymermaterial 5 und dem Displayträger 1 verbunden und dadurch waagerecht in der Blendenöffnung 2 montiert. In the next step, the display support 1 is aligned horizontally. After the polymer material 5 has hardened, an optical adhesive liquid 8 is applied to the side of the hardened polymer material 5 facing the diaphragm opening 2 in the area of the diaphragm opening 2 . The display 4 is then attached to the shoulder 6 and connected to the polymer material 5 and the display support 1 by means of the optical adhesive liquid 8 and is thereby mounted horizontally in the panel opening 2 .
Das in der Figur 2 dargestellte zweite Ausführungsbeispiel ermöglicht im Vergleich zu dem in der Figur 1 dargestellten ersten Ausführungsbeispiel eine Montage des Displays 4 nach der Beschichtung des Displayträgers 1 mit dem Polymermaterial 5. In comparison to the first exemplary embodiment shown in FIG. 1, the second exemplary embodiment shown in FIG. 2 enables the display 4 to be mounted after the display carrier 1 has been coated with the polymer material 5.
Die in der Figur 3 skizzierte dritte Ausführungsvariante sieht vor, dass in einem ersten Schritt der Displayträger 1 derart durch Spritzgießen geformt wird, dass eine zur Außenseite 13 des Displayträgers 1 parallele Anformung 9 entsteht. The third embodiment variant outlined in FIG. 3 provides that in a first step the display support 1 is formed by injection molding in such a way that a projection 9 parallel to the outside 13 of the display support 1 is formed.
Der Displayträger 1 bildet so eine zu seiner Außenseite 13 offene Blendenkammer 12 aus, deren Tiefe der Höhe des anzufügenden Displays 4 entspricht. Das Display 4 weist einen in der Figur 3 explizit dargestellten elektrischen Anschluss 7 aus mehreren skizzenhaft dargestellten Anschlussleitungen auf. The display carrier 1 thus forms an aperture chamber 12 which is open towards its outer side 13 and whose depth corresponds to the height of the display 4 to be attached. The display 4 has one shown explicitly in FIG electrical connection 7 from several connection lines shown sketchy.
Innerhalb der Anformung 9 befindet sich eine Öffnung 10, durch die der elektrische Anschluss 7 des Displays 4 geführt werden kann. Um die ÖffnungThere is an opening 10 within the projection 9 through which the electrical connection 7 of the display 4 can be guided. around the opening
10 herum befindet sich eine Dichtung 11 , die aus einem gestanzten Kleberahmen oder einer flüssigen Klebung besteht. Around 10 is a seal 11 made of die-cut glue frame or liquid glue.
Im folgenden Schritt wird das Display 4 in die Blendenkammer 12 eingesetzt, wobei der Anschluss 7 durch die Öffnung 10 hindurchgeführt wird. In the following step, the display 4 is inserted into the aperture chamber 12, with the connector 7 being passed through the opening 10.
Abschließend erfolgt eine Über- und Umflutung des Displayträgers 1 samt Display 4 in einer vertikalen Lage, um das Einschließen von Luft zu vermeiden. Finally, the display support 1 together with the display 4 is flooded and flooded in a vertical position in order to avoid air being trapped.
