Description

The invention relates to a mechatronic mainboar extension, in particular for control units such as PC systems. Each control unit is based on the use of predetermined main or motherboards with different top and possibly underside hardware assembly. The mainboards are usually uniform in size, in particular, they have a manufacturer-related uniform mechanical and thermal design with plug and interface arrangements. The mechatronic mainboar extension according to the invention, which is based on the arrangement of at least one riser interface, leads both to a higher flexibility in the setup of expansion options in control systems and to an optimization of the cooling of these control units, so that from this combination one for the average person skilled in the art unpredictable Performance increase of the control systems results. Accordingly, according to the teaching of the invention, at least one edge region of a mainboard or motherboard is equipped with the aforementioned mechatronic mainboard extension.

The state of the art includes motherboards and PC motherboards z. In Mini ITX format, whose expansion options are limited by manufacturer-specific enclosures. There are only defined within the housing frame defined slots for expansion measures z. B. with maps available. The hitherto generally customary architecture of control units or processor platforms thus considerably reduces the flexibility of these known objects. In addition, the removal of the heat loss is difficult in this known construction.

The invention has for its object to provide a mechatronic main or motherboard extension, with which, unlike the prior art, the flexibility of the control units and the cooling system can be significantly improved.

• 1. Die Riser-Schnittstelle eines Main- bzw. Motherboards, der Basisplatine ist mit einem einseitigen Riser-Stecker verbunden, an dessen Rückseite eine Verbindungsplatine aufgelötet ist, die bei angenommener horizontaler Lage der Basisplatine parallel zur Riser-Schnittstelle senkrecht nach unten weist. Die Verbindungsplatine ist mit wenigstens einem parallel zur Riserkante der Basisplatine beabstandet verlaufenden Verbindungsstecker zur Aufnahme wenigstens einer bestückten Erweiterungskarte parallel unterhalb des Mainboards ausgestattet. Die Möglichkeit der Anordnung weiterer Verbindungsstecker und Erweiterungskarten ist von der jeweiligen Abmessung der Verbindungsplatine abhängig. Da die Hauptwärmeerzeuger der Hardware-Bestückung wie CPU-Modul und/oder Embedded-Systems-Modul auf oder oberhalb der Basisplatine angeordnet sind, und darüber nur noch das passive und/oder aktive Kühlelement einheiltlich beabstandet platziert ist, wird mit der erfindungsgemäßen Verlagerung der Erweiterungsmöglichkeiten in den Bereich unterhalb der Basisplatine des Main- bzw. Motherboards die Ableitung der Verlustwärme in keiner Weise durch eventuell dazwischen angeordnete Erweiterungskarten, wie es nach dem Stand der Technik wiederholt der Fall ist, beeinträchtigt.
• 2. Die Riser-Schnittstelle des Main- oder Motherboards ist mit einem Kombi-Riser-Stecker verbunden, dessen eine Seite als Platinensteckverbinder mit hoher Polzahl und dessen andere Seite als Steckverbinder zur Aufnahme einer bestückten, horizontal anzuordnenden Erweiterungskarte ausgeführt ist. Durch die endseitige Ausstattung des Kombi-Riser-Steckers mit einem Steckverbinder, mit dem die in Betracht kommende bestückte Erweiterungskarte zu verbinden ist, wird zusätzlich eine horizontale mechatronische Mainboarderweiterung erreicht. Alternativ kann die Erweiterungskarte auch mit dem Kombi-Rise-Stecker fest verlötet sein. Auch diese Form der horizontalen Ver- oder Auslagerung der mechatronischen Erweiterungsmöglichkeiten in außerhalb eines Main- oder Motherboards liegende Bereiche trägt entscheidend zur Verbesserung der passiven und/oder aktiven Kühlung von Steuerungseinheiten bei, weil damit eine Beeinträchtigung der Wärmeableitung von den Hauptwärmeerzeugern der Hardware-Bestückung gezielt ausgeschlossen wird.

This object is achieved according to the teachings of the invention in a manner which is surprisingly simple for the person skilled in the art in that the base board which is suitable for the control unit and which is used as the mainboard or motherboard after the hardware assembly has at least one riser edge area. which is realized as a riser interface in the embodiment as a board connector with a high number of poles. The riser interface according to the invention allows the following mechatronic expansion forms for control units of the type in question after hardware assembly:

• 1. The riser interface of a motherboard and motherboard, the base board is connected to a one-sided riser connector, on the back of a connection board is soldered, which points at the horizontal position of the base board parallel to the riser interface vertically downwards. The connection board is equipped with at least one parallel to the riser edge of the base board extending connector for receiving at least one populated expansion card parallel below the motherboard. The possibility of arranging further connection plugs and expansion cards depends on the respective dimension of the connection board. Since the main heat generators of the hardware assembly such as CPU module and / or embedded system module are arranged on or above the base board, and about only the passive and / or active cooling element is placed einheiltlich spaced, with the inventive displacement of the expansion options in the area below the motherboard motherboard, the dissipation of the lost heat in any way by possibly interposed expansion cards, as is repeatedly the case in the prior art, impaired.
• 2. The riser interface of the motherboard or motherboard is connected to a combi-riser connector, one side of which is designed as a board connector with a high number of poles and the other side as a connector for receiving a populated, horizontally arranged expansion card. Due to the end equipment of the combi-riser connector with a connector, with which the suitable populated expansion card is to be connected, an additional horizontal mechatronic mainboard extension is achieved. Alternatively, the expansion card can also be firmly soldered to the Kombi-Rise connector. This form of horizontal storage or outsourcing of mechatronic expansion options in lying outside a main or motherboard areas contributes significantly to the improvement of the passive and / or active cooling of control units, because thus targeted an impairment of heat dissipation from the main heat generators of the hardware is excluded.

The mainboard extension according to the invention is usually based on a CPU module according to industry standard such as COM Express according to PICMG Standard COM.0 as a control-engineering core, which enables scalability of the computing power, memory equipment and graphics performance. The improvement of the cooling performance is according to the invention achieved mechatronic structure in that above the motherboard assembly, which usually u. A. With a CPU module, if necessary in combination with an embedded system module u. Like. Is equipped as a main heat generator, only the active and / or passive plate-shaped cooling system is arranged. The mechatronic Mainboarderweiterung according to the invention prevents impairment of the cooling performance by overshadowing the heat dissipation due to arranged expansion cards, as is still common in the prior art in which arranged at least one expansion card either parallel below the motherboard or peripherally continued outside the mainboard area horizontally ,

Instead of the known expansion possibilities, which usually provide slots for plug-in cards on mainboards, according to the invention, the mechatronic mainboard expansion is achieved with a riser interface arrangement, which may optionally include several standard bus systems such as PCI and PCI Express. In combination with other different riser plug-in cards, a variety of combination options is created, which also significantly improves the performance of control units with main or motherboard assembly quality and quantity significantly.

The invention is based on the following, not to scale, limited to the essentials representations of the structure of the mechatronic Mainboarderweiterungsmöglichkeiten according to the 1a and 1b , which refer to the vertical extension form below the respective motherboard, and according to the 2a and 2 B , which refer to the horizontal extension form below the respective motherboard, explained in more detail.

1a shows in plan view an embodiment for a rectangular main or motherboard 1 on mini ITX standard basis, which in practice for example has a length of 170 mm and a width of 170 mm. The main or motherboard 1 has a central area 2 , in which usually the essential control units such as a CPU module, if necessary in combination with an embedded system module u. Like. Are arranged as the main heat generator. Above this central area 2 is the passive and / or active plate-shaped cooling system 3 spaced apart from the assembly. In addition, a not shown cooling technical housing connection can be provided. The one from the central area 2 not covered edge areas are provided for the arrangement of interfaces and other equipment forms. In the graphic representation is, for example, on one side of the main or motherboard 1 a marginal surface area 4 for a plug or interface arrangement 5 intended. Above the central area 2 with the essential hardware equipment 15 , which generates the majority of the heat loss, is a passive and / or active cooling element with respect to the highest component 3 , which is designed for example as a cooling plate, in height uniformly from the motherboard or motherboard 1 spaced apart. To increase the cooling capacity may optionally be provided not shown active cooling element. According to the teachings of the invention is on at least one edge region 7 of the main or motherboard 1 to reserve a certain surface area for the mechatronic mainboard extension. In the illustrated embodiment is outside the central area 2 of the main or motherboard 1 and orthogonal to the surface area 4 the surface area leading to mechatronic expansion 6 intended. The edge area 7 of the surface area 6 is with a riser arrangement 8th to equip, according to the graphical representation in the form of parallel spaced, narrow contact points 10 is executed and spread over the length of the edge area 7 extends. This is a riser interface 8th in combination with a board connector 9 with high number of poles available on the riser arrangement 8th of the edge area 7 is plugged. The board connector 9 is electrically conductive on the back, for example via a solder joint, with a connection board 14 related to the assumed horizontal position of the mainboard or motherboard 1 placed at right angles downwards. The connection board 14 is also with at least one below and parallel arranged connector 11 for receiving a populated expansion card 12 fitted. Thus, the mechatronic mainboar extension is realized in a surprisingly simple manner for the average expert.

1b shows in side view the on the edge surface area 4 of the main or motherboard 1 arranged plug or interface arrangement 5 , the central area behind it 2 with the main heat generators, not shown, such as CPU module and / or embedded system module and the plate-shaped passive cooling element arranged above it 3 , Starting from the assumed horizontal position of the mainboard or motherboard 1 is the edge area 7 with the riser arrangement 8th and spaced therefrom the downwardly angled interconnect board 14 shown. The connection board 14 is with the on the riser arrangement 8th aligned board connector 9 with a high number of poles and the connector underneath and parallel thereto 11 for receiving a populated expansion card 12 fitted.

2a shows in plan view and 2 B in side view the structure of the main or motherboard 1 like this one in 1a and 1b is shown and described, so that it can be fully referenced for reasons of avoiding repetition. The only difference is the horizontal mechatronic mainboar extension after form-fitting assembly. After that is the main or motherboard 1 via a combination riser plug 13 , one side of which as a board connector 9 with a high number of poles and the other side as a connector 11 is executed, with a populated expansion card 12 connected horizontally. Thus, the mechatronic mainboar extension is also realized in a way that is surprisingly simple for the average person skilled in the art.
