Description

Technical Field

[0001] The utility model relates to the technical field of MXM graphics cards, in particular to a separate MXM graphics card expansion structure. Background Art

[0002] MXM, or Mobile PCI Express Module, is a set of device interfaces designed for graphics processors based on the PCI-Express interface. It is targeted at different types of notebook products and is jointly developed by nVidia and several notebook computer manufacturers. It uses a communication protocol compatible with PCI-Express, so it can be used in all graphics cores that support PCI-Express specifications and chipsets that support PCI-Express graphics interfaces. It not only shortens the product design cycle, but also allows manufacturers to provide different levels of MXM graphics card products based on different user needs. Users can upgrade the MXM graphics card by themselves in the future as needed without having to replace the entire notebook computer.

[0003] In the prior art, the MXM slot is directly welded on the motherboard, and the four output channel connectors of the graphics card are fixed and cannot be changed at will. Since the MXM slot and the motherboard are together, its output channel connector is fixed. There are cases where the four output channel connectors of some graphics cards are different. In this case, the different channels cannot be used. In addition, the installation position of the MXM graphics card is also fixed and cannot be changed at will.

[0004] Although current technology also uses expansion connections that are separated from the motherboard, most of them are used in the server field for storage such as hard disk expansion connections, and are rarely used for graphics card connections.

[0005] Therefore, it is of great significance to study a separate MXM graphics card expansion structure to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the output channel connector cannot be flexibly changed according to actual usage due to the integrated design of the MXM graphics card and the motherboard, that is, the display channels of different models of MXM graphics cards do not match the signal output connectors, resulting in the inability to output display signals, as well as the problems of inflexible spatial layout and unreasonable heat dissipation ducts.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A separate MXM graphics card expansion structure comprises a mainboard and an MXM carrier board which are separated from each other, an MXM graphics card being installed on the MXM carrier board, an SFF8654-8I connector I being arranged on the mainboard, and an SFF8654-8I connector II being arranged on each of the MXM carrier boards, the SFF8654-8I connector I of the mainboard and the SFF8654-8I connector II of the MXM carrier board being connected via a flexible flat cable, wherein the connection method is to transmit a PCIE x8 signal from the mainboard end to the MXM carrier board end via an SFF8654-8I cable.

[0009] The utility model designs the integrated motherboard and MXM carrier board of the prior art into a separate type, adopts SFF8654-8I connector and matching cable and MXM carrier board to realize MXM expansion structure, and is provided with SFF8654-8I connector on the motherboard, which contains PCIE8X signal and is connected to MXM carrier board through SFF8654-8I flexible cable. At this time, the power supply data of the motherboard are connected to MXM graphics card through flexible cable. MXM carrier board can be freely replaced according to the output interface of different graphics card types, and the motherboard does not need to be changed. SFF-8654 rev-1.2 is a specification standard, which specifies the physical characteristics and electrical performance of a new type of high-speed serial interface connector. The main features of SFF-8654 rev-1.2 standard include scalability, high-speed performance and flexibility. It supports multiple serial connection protocols and can meet the data transmission requirements between different types of devices. At the same time, it also supports multi-channel connection, so that the device can transmit multiple data streams at the same time, improving data processing efficiency. In addition, the MXM graphics card installed on the separate MXM carrier board can be freely replaced according to the output interface of different graphics card types. Compared with the existing integrated structure that causes the non-replaceability of the MXM graphics card or the inconvenience of replacing the MXM graphics card and needing to replace the output interface on the motherboard accordingly, it has more application value.

[0010] As the preferred technical solution:

[0011] As described above, a separate MXM graphics card expansion structure is provided on the mainboard, and a VSYS power connector I is also provided on the mainboard, and a 12-19V power supply is transmitted to the MXM carrier board end through a PH2.0 6P cable.

[0012] In the above-described separated MXM graphics card expansion structure, the flexible flat cable is covered by a waterproof sealing tube.

[0013] In the above-described separate MXM graphics card expansion structure, the MXM carrier board is provided with an MXM connector, the MXM connector is installed with a slot, and the MXM graphics card is replaceably plugged into the slot.

[0014] In the above-mentioned separate MXM graphics card expansion structure, the MXM carrier board is also provided with a heat sink and a display output interface HDMI.

[0015] In the above-described separate MXM graphics card expansion structure, the heat sink is a copper heat sink that is fixed by screws and fixing holes around the MXM carrier board.

[0016] In the above-described separate MXM graphics card expansion structure, the SFF8654-8I connector I and the SFF8654-8I connector II support multiple serial connection protocols, including PCIe, SAS or SATA.
