Description

Technical Field

[0001] The utility model relates to the technical field of computer hardware, and more specifically to the technical field of a compatible computer mainboard structure. Background Art

[0002] The motherboard, also known as the motherboard, mainboard, or logic board, is one of the most important circuit boards in a computer system. It is the foundation for all the major components of a computer to connect and communicate. It is responsible for providing connections and interfaces, typically including the central processing unit (CPU) socket, memory slots, storage interfaces, PCIe slots, etc., enabling the central processing unit (CPU), memory, storage devices (such as hard drives and solid-state drives), input / output devices (such as graphics cards, sound cards, and network adapters), and other expansion cards (such as USB or network interface cards) to communicate and work together.

[0003] Different computer types typically require corresponding motherboard models. This is because the motherboard's specifications, performance, and functional design must match the computer's intended use and components. In traditional terminal computer platform design, after a new CPU platform is released, various manufacturers will develop corresponding desktop computers, all-in-one computers, and thin clients based on this CPU platform to meet different customer needs. Due to the different structures of these three products, traditional designs often require the development of multiple motherboards. Utility Model Content

[0004] The purpose of this utility model is to provide a motherboard compatible with multiple application scenarios, so that one motherboard can be applied to multiple products, which can significantly shorten the development cycle and reduce software and hardware development and production costs.

[0005] The utility model is achieved through the following technical solutions:

[0006] A motherboard compatible with multiple application scenarios includes a circuit board body and a PCIe interface located above the circuit board body. The PCIe interface includes a first PCIe slot assembly, a second PCIe slot assembly, and an adapter plugged into the second PCIe slot assembly. The first PCIe slot assembly extends in a direction parallel to that of the circuit board body and is disposed at an edge of the circuit board body. The second PCIe slot assembly is disposed perpendicularly to the circuit board body. The adapter includes an adapter for connecting an expansion card. The adapter extends in a direction parallel to that of the circuit board body.

[0007] Different computer types, such as desktops, all-in-ones, and thin clients, have different space constraints and form factors. The size, shape, and layout of the motherboard must adapt to these constraints and requirements. This technical solution provides a motherboard compatible with multiple application scenarios. By providing a first PCIe slot assembly, a second PCIe slot assembly, and an adapter plugged into the second PCIe slot assembly, it is compatible with desktop, all-in-one, and thin client chassis. PCIe stands for Peripheral Component Interconnect Express, a high-speed computer bus standard.

[0008] For example, in some application scenarios for all-in-one computers, the fuselage often pursues a light and thin effect, so the size of the space perpendicular to the motherboard is relatively restricted. Since the first PCle slot assembly is arranged parallel to the edge of the circuit board body, the expansion card can be directly connected and installed. On the one hand, since the extension direction of the first PCle slot assembly is parallel to the extension direction of the circuit board body, the extension direction of the expansion card is also parallel to the circuit board body, thereby saving the vertical space on the motherboard, so the space limitation of the all-in-one computer can be solved. On the other hand, since the first PCle slot assembly is arranged at the edge of the circuit board body, it is ensured that the expansion card plugged into the first PCle slot assembly has the largest heat exchange area, which can better achieve heat dissipation.

[0009] In some desktop computer applications, the motherboard space constraints are limited due to its larger size. However, the pursuit of high performance and high power consumption requires a motherboard with a large number of slots and interfaces and good heat dissipation. Because the second PCIe slot assembly is positioned vertically on the main circuit board, the number of expansion cards is unlimited, meeting high performance requirements. Furthermore, this vertical arrangement maximizes heat exchange area, allowing expansion cards to be plugged into the second PCIe slot assembly, ensuring high performance while maintaining good heat dissipation efficiency.

[0010] In thin client applications, which often require a smaller body and prioritize energy efficiency and cost control, performance is typically sufficient to meet basic office needs. The adapter on the second PCIe slot assembly allows expansion cards to be placed parallel to the motherboard, resulting in a higher level of integration and meeting the constraints of a smaller footprint.

[0011] This technical solution provides a motherboard compatible with multiple application scenarios. By providing a first PCIe slot assembly, a second PCIe slot assembly, and an adapter plugged into the second PCIe slot assembly, it is compatible with desktop computers, all-in-one computers, and thin client chassis. This multi-application compatibility significantly shortens development cycles and reduces software and hardware development and production costs.

[0012] As a preferred embodiment of the present invention, a half-height, half-length graphics card is plugged into the PCle interface.

[0013] A half-height, half-length graphics card is one that is half the height and half the length of a standard graphics card. This type of graphics card is particularly useful in situations where space is limited, such as in servers or compact chassis.

[0014] As a preferred embodiment of the present invention, the motherboard compatible with multiple application scenarios further includes a CPU and a PCIe Switch located on the circuit board body, and both the CPU and the PCIe Switch are connected to the PCle interface.

[0015] The CPU (Central Processing Unit) uses the Sunway Weiyan SW-WY831 processor, with a clock speed of ≥2.5GHz and eight integrated computing cores. The PCIe switch (Peripheral Component Interconnect Express Switch) uses the PEX8733, which is used for PCIe 3.0 bus expansion and connects to the CPU via PCIeEx8. The PEX8733 is a PCIe 3.0 switch with 32 lanes and up to 18 ports, enabling data exchange between these ports.

[0016] As a preferred embodiment of the present invention, the motherboard compatible with multiple application scenarios further includes an expansion interface connected to the PCIeSwitch.

[0017] The expansion interface can be an M.2Key interface, connected to the PCIe Switch via PCIe signals, to expand hard drives, wireless network cards, and Bluetooth modules. Specifically, the M.2Key E interface can expand wireless network cards and Bluetooth; the M.2KeyM interface can expand NVME hard drives and SATA hard drives.

[0018] As a preferred embodiment of the present invention, the circuit board body has a size of 244 mm×244 mm.

[0019] An mATX motherboard measures 244mm x 244mm. mATX, short for Mini ATX, is a computer motherboard form factor. It's smaller than a standard ATX motherboard but larger than a Micro ATX (mATX) motherboard. mATX motherboards are commonly used in small and medium-sized computer cases, offering excellent expandability while maintaining a compact size. This form factor allows for smaller power supplies and typically supports standard-sized memory modules and processors.

[0020] As a preferred embodiment of the present invention, the motherboard compatible with multiple application scenarios further includes a DC power interface and an ATX power interface located on the circuit board body.

[0021] The DC (Direct Current) power interface is suitable for thin clients and all-in-one computers. The ATX (Advanced Technology Extended) power interface is an interface standard for connecting a computer power supply to the motherboard. It was introduced by Intel in 1995 and is suitable for desktop computers.

[0022] As a preferred embodiment of the present invention, the motherboard compatible with multiple application scenarios further includes a CPU heat sink and a PCIe Switch bridge heat sink located on the circuit board body.

[0023] As a preferred embodiment of the present invention, the motherboard compatible with multiple application scenarios further includes a USB controller, the upstream of the USB controller is connected to the PCIe Switch, and the downstream includes multiple USB ports.

[0024] The USB (Universal Serial Bus) controller uses the China Resources Microelectronics CS4320EN to expand USB resources. The CS4320EN connects to the PEX8733 via PCIe x1 upstream and supports four USB 3.0 ports downstream.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. By providing a first PCIe slot assembly, a second PCIe slot assembly, and an adapter plugged into the second PCIe slot assembly, the system is compatible with desktop computers, all-in-one computers, and thin client chassis. This enables compatibility across multiple application scenarios, significantly shortening development cycles and reducing software and hardware development and production costs.

[0027] 2. Use a half-height, half-length graphics card to plug into the PCle interface, which is suitable for servers or compact chassis and has strong scalability.

[0028] 3. The main body of the circuit board has a size of 244mm x 244mm. This motherboard size is commonly used in small and medium-sized computer cases. They can accommodate smaller power supplies and usually support standard-sized memory sticks and processors, providing better scalability while maintaining a relatively compact size.

DETAILED DESCRIPTION

[0035] The present invention will be described in further detail below with reference to the accompanying drawings.

[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0037] like Figure 1As shown, a motherboard compatible with multiple application scenarios includes a circuit board body and interface components and hardware components located above the circuit board body. The interface components include: PCle interface 1; indicator light signal interface 2, dedicated to all-in-one computers and desktop computers.

[0038] The PCIe interface 1 includes a first PCIe slot assembly 1-1, a second PCIe slot assembly 1-2, and an adapter (not shown) plugged into the second PCIe slot assembly 1-2.

The second PCIe slot assembly 1-2 is perpendicular to the main circuit board. The adapter includes a connector for connecting an expansion card, extending parallel to the main circuit board. The expansion card plugged into the PCIe interface 1 is a half-height, half-length graphics card 14. A half-height, half-length graphics card 14 is half the height and length of a standard graphics card. This type of graphics card is particularly useful in space-constrained environments, such as servers or compact chassis.

[0039] like Figure 2 As shown, this motherboard compatible with multiple application scenarios also includes hardware components connected to the above interfaces, specifically:

[0040] CPU: The CPU (Central Processing Unit) uses the Shenwei Weiyan SW-WY831 processor with a main frequency of ≥2.5GHz and 8 integrated computing cores;

[0041] PCIe Switch: The PCIe Switch (Peripheral Component Interconnect Express Switch) uses the PEX8733, which is used for PCIe 3.0 bus expansion and connects to the CPU via PCIe x8. The PEX8733 is a PCIe 3.0 switch with 32 lanes and up to 18 ports, enabling data exchange between these ports.

[0042] The USB controller uses the China Resources Microelectronics CS4320EN to expand USB resources. The CS4320EN connects to the PEX8733 via PCIex1 upstream and can expand four USB 3.0 channels downstream.

[0043] A Complex Programmable Logic Device (CPLD) uses the Aogaxon AG256SL100, which is used for fan control, power-on sequencing, chip reset control, level conversion, and power status monitoring. The AG256SL100 has 80 user I / O pins and 256 logic units (LEs), supporting various I / O interfaces and a variety of embedded hard cores.

[0044] Memory stick: Use SO-DIMM (small outline dual in-line memory module) interface memory stick.

[0045] Network controller: uses RTL8111H, connected to PEX8733 via PCIe x1 uplink, and can expand 1 Gigabit network port downlink.

[0046] SATA controller: uses JMB585, connected to PEX8733 via PCIe x1 uplink, and can expand 4-way SATA3.0 signal downlink, 3 of which are connected to 7-pin SATA connector and 1 is connected to M.2Key M connector, which can expand hard disk.

[0047] RS232 transceiver: Use SIT3232E, and connect the UART signal to the DB9 interface for CPU serial port debugging.

[0048] Audio controller: Use Huaxun CM6206, connected to the USB2.0 interface 4-2 expanded by the CS4320EN chip. CM6206 outputs audio signals to connect to headphones and microphone sockets, and can also switch to the audio power amplifier chip TPA1517DWPR to drive the speakers.

[0049] Different computer types, such as desktops, all-in-ones, and thin clients, have different space constraints and form factor requirements. The size, shape, and layout of the motherboard must adapt to these constraints and requirements. This technical solution provides a motherboard compatible with multiple application scenarios. By providing a first PCIe slot assembly 1-1, a second PCIe slot assembly 1-2, and an adapter plugged into the second PCIe slot assembly 1-2, this motherboard is compatible with desktop, all-in-one, and thin client chassis.

[0050] For example, in some all-in-one computer applications, the body is often designed to be thin and light, so the space vertical to the motherboard is highly restricted. Figure 3 As shown, in order to save space perpendicular to the motherboard, the half-height, half-length graphics card 14 is directly plugged into the first PCIe slot assembly 1-1. The CPU, PCIe Switch bridge integrated heat sink and fan are installed in the side area of the circuit board body. On the one hand, since the extension direction of the first PCIe slot assembly 1-1 is parallel to the extension direction of the circuit board body, the extension direction of the expansion card is also parallel to the circuit board body, thereby saving space in the vertical direction on the motherboard, and thus solving the space limitation of the all-in-one machine. Moreover, the integrated heat sink conducts heat through the connecting piece and dissipates heat through wind speed, which can further save space in the vertical direction on the motherboard while solving the heat dissipation problem. On the other hand, since the first PCIe slot assembly 1-1 is set at the edge of the circuit board body, it is ensured that the expansion card plugged into the first PCIe slot assembly 1-1 has the largest heat exchange area, which can better achieve heat dissipation.

[0051] In some desktop computer applications, due to the large size of the computer, the space restrictions on the motherboard are relatively small. However, due to the pursuit of high performance and high power consumption, the motherboard needs to be equipped with more slots and interfaces and has better heat dissipation. Figure 4 As shown, a half-height, half-length graphics card 14 is inserted vertically into the second PCIe slot assembly 1-2. A CPU heatsink 15, fan, and PCIe switch bridge heatsink 16 are mounted directly above the CPU and PCIe switch. Because the second PCIe slot assembly 1-2 is vertically mounted on the circuit board, the number of expansion cards is unlimited, meeting high-performance requirements. Furthermore, this vertical arrangement maximizes heat exchange area, allowing expansion cards to be plugged into the second PCIe slot assembly 1-2 while maintaining high performance and achieving excellent heat dissipation efficiency.

[0052] In some thin client application scenarios, the body is often small, and the focus is on energy efficiency and cost control, and the performance usually meets basic office needs. Figure 5 As shown, the half-height, half-length graphics card 14 can be set in parallel above the mainboard through the adapter on the second PCle slot assembly 1-2, so that the mainboard has a higher degree of integration, thereby meeting the limitation of smaller volume.

[0053] Since the CPU heat sink 15 and the fan as well as the PCIe Switch bridge heat sink 16 occupy a relatively small vertical space, they can be directly installed above the CPU and the PCIe Switch.

[0054] As a preferred embodiment of this invention, the circuit board body has a size of 244mm x 244mm. The size of an mATX motherboard is 244mm x 244mm. mATX is the abbreviation of Mini ATX, which is a computer motherboard form factor. This motherboard is smaller than a standard ATX motherboard, but larger than a Micro ATX (mATX) motherboard. mATX motherboards are commonly used in small and medium-sized computer cases. They provide good expandability while maintaining a relatively compact size. Motherboards of this specification can accommodate smaller power supplies and generally support standard-sized memory modules and processors.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
