Description

A computer motherboard module

technical field

The utility model relates to a main board type module, in particular to a computer main board type module with an X86 structure.

Background technique

Industrial computer motherboards are widely used in all walks of life and fields, and are the foundation and core of the information technology era. Major industrial motherboard manufacturers have developed standard motherboards with different configurations and I/O ports. However, industrial control motherboards are different from commercial motherboards. The output cannot compete with commercial motherboards, but the quality requirements are higher than ordinary commercial motherboards. If the development of an industrial control motherboard cannot guarantee a certain market share, it will face the risk of failure of the motherboard. In order to adapt to different market segments, different motherboards must be developed, and there may be only slight differences between them, which is very disadvantageous for production management and sales.

The commonly used solution in the market is to use a standard COM (Computer-On-Module) module. Its main feature is to integrate the three major components of the CPU, South Bridge, and North Bridge into a PCB with a size of about 114×95 mm. , through 2 or 4 high-density board-board connectors to connect with the carrier board (that is, the custom IO carrier board used in conjunction with the CPU module), but the price is high, and it is not easy for ordinary users to accept the price. An important factor for the high price of COM modules is that the material selection requirements for the high-density board-board connectors on the modules are extremely strict. The cost of this part can no longer be underestimated, so it is difficult to really reduce the price, and the seismic performance is poor and the installation requirements are high. .

To sum up, aiming at the defects of the prior art, there is a special need for a computer motherboard module to solve the above-mentioned problems.

Utility model content

The purpose of this utility model is to provide a computer motherboard module, which solves the above-mentioned defects of the prior art, saves the dependence on high-quality board-board connectors, greatly reduces the cost, has a simple structure, and is very practical.

The technical problem solved by the utility model can be realized by adopting the following technical solutions:

A kind of computer motherboard type module, comprises a standard motherboard module, it is characterized in that, the side of described motherboard module is provided with a first PCI-Express slot that is used for graphics card expansion, and the bottom of described motherboard module is provided with for Second PCI-Express slot and third PCI-Express slot for expansion bus and dedicated signals.

In one embodiment of the present invention, the first PCI-Express slot is an 8-bus slot.

In one embodiment of the present utility model, the second PCI-Express slot is an 8-bus slot.

In one embodiment of the present invention, the third PCI-Express slot is a 16-bus slot.

The computer motherboard module of the utility model adopts standard slots as expansion connectors, which saves the dependence on high-quality board-board connectors, greatly reduces costs and increases flexibility; the development cycle of I/O sub-boards is long The cycle of developing the main board is shorter, and the product can be put into the market competition at the fastest speed, so as to realize the purpose of the utility model.

The features of the utility model can be clearly understood by referring to the drawings of this case and the detailed description of the following preferred embodiments.

Fig. 1 is the structure schematic diagram of the computer motherboard type module of the present utility model.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, the computer motherboard module of the present utility model comprises a standard motherboard module 100, is provided with a first PCI-Express slot 110 for graphics card expansion at the side of described motherboard module 100, described The bottom of the motherboard module 100 is provided with a second PCI-Express slot 120 and a third PCI-Express slot 130 for extending the bus and dedicated signals.

In the present utility model, the first PCI-Express slot 110 is an 8-bus slot. The second PCI-Express slot 120 is an 8-bus slot. The third PCI-Express slot 130 is a 16-bus slot.

The computer motherboard type module of the utility model uses the second PCI-Express slot 120 and the third PCI-Express slot 130, and the pin sum reaches 246, including PCI, PCI-Express expansion bus and IDE, DVI, VGA And proprietary signals such as serial ports.

The side of the motherboard module 100 is also designed with a dedicated expansion position for the first PCI-Express slot 110 for the graphics card. When there is a special need for the graphics card, this expansion bus can be used to expand the independent graphics card. According to the application, the user can develop the interface I/O sub-board by himself, and arrange the positions of various interfaces on the sub-board.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model, and the claimed protection scope of the utility model is defined by the appended claims and their equivalents.
