Technical Field

[0001] This utility model belongs to the field of COME board technology, specifically relating to a COME board with multiple expansion interfaces. Background Technology

[0002] With the widespread application of computer technology in various fields, the requirements for the performance and expandability of computer hardware are becoming increasingly stringent. COME (COMExpress) boards, as a type of modular computer motherboard, are widely used in many fields such as industrial control, medical equipment, and communication systems due to their advantages of compact size, high performance, multiple interface functions, and good interchangeability.

[0003] However, existing COME boards often have limitations in the number and types of expansion interfaces, making it difficult to meet the growing demand for diverse device connections and functional expansion. For example, in some industrial automated production lines, multiple sensors, actuators, communication modules, and other devices need to be connected simultaneously, and existing COME boards may not provide a sufficient number of serial ports, USB interfaces, PCIe interfaces, etc. In some applications with high graphics processing requirements, such as medical image processing and virtual reality, the display interfaces of existing COME boards may not meet the needs of multi-screen displays or high-resolution displays.

[0004] Therefore, developing a COME board with more expansion interfaces that can meet diverse application needs is of great practical significance. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0013] Customized expansion interface modules include GPIO interface, LPC interface, and SPI interface.

[0014] Preferably, the four USB 2.0 ports, four USB 3.0 ports, and two 10 / 100 / 1000Mb adaptive gigabit Ethernet ports are located on the outside of the COME board and in an easily accessible position close to the outer edge of the COME board.

[0015] Preferably, one set of PCIe 3.0 x8 interfaces and two sets of PCIe 2.0 x8 interfaces are centrally installed on the left side of the COME board, and their interference with other interfaces is reduced through reasonable wiring and shielding measures.

[0016] As a preferred option, the three SATA3.0 interfaces are located away from the power circuitry on the COME board.

[0017] As a preferred option, both the USB 2.0 and USB 3.0 interfaces use a non-detachable plug-in interface.

[0018] As a preferred embodiment, the anti-dislodge pluggable interface includes a USB female connector and a housing, with the USB female connector being inserted into the housing and then sealed inside the housing.

[0019] The bottom of the casing has a through hole for the pins of the USB female connector to pass through. The clip on the USB female connector snaps into the bottom of the casing and is located on the bottom plate in front of the through hole.

[0020] The two side plates of the casing are equipped with spring pieces B that engage with the limiting groove on the USB female connector.

[0021] The two side plates of the casing are equipped with two symmetrically arranged buckles. The bending plates on the left and right sides of the casing are folded to the openings on the left and right sides of the casing. The buckles on the bending plates cooperate with the buckles to achieve the encapsulation and positioning of the USB female connector.

[0022] Preferably, the front side of the casing has symmetrically arranged limiting plates that limit the USB female connector within the casing. The inner sides of the two limiting plates have spring clips A that clamp the male connector of the inserted USB female connector. The front sides of the USB female connector have slots that cooperate with the spring clips A to limit and abut.

[0023] Preferably, the bottom sides of the casing are provided with two bending strips that penetrate the COME plate and fix the casing to the COME plate.

[0024] Preferably, the USB female connector has a plug block for inserting the male connector in the plug slot, and the upper and lower ends of the plug block are respectively provided with spring pieces C that are engaged and positioned to match the holes on the male connector.

[0025] As a preferred option, the COME board supports 64-bit data width and 8 / 16-bit memory chips to configure memory capacity according to user needs. In terms of interface layout, the COME board places commonly used interfaces in easily accessible locations and rationally isolates and arranges high-speed interfaces and interference-sensitive interfaces.

[0026] Compared with the prior art, the technical effects and advantages of this utility model are:

[0027] This invention achieves functional expansion by integrating PCIe, USB, SATA, and other modules. High-speed interfaces are centralized and shielded to reduce interference, while commonly used interfaces are externally mounted for easy plugging and unplugging. Memory can be configured as needed. This design not only meets the high-performance requirements of scenarios such as server big data processing and high-speed industrial data acquisition, but also adapts to diverse applications through dual gigabit network port redundancy and multiple display interfaces. The reserved customized interfaces provide further expansion space for specific industry needs.

[0028] The USB interface in this utility model adopts an anti-detachment design where the female connector is encapsulated in the housing. The bottom through hole and locking position, the side plate spring piece B and the limiting groove, and the front limiting plate and spring piece A form a three-dimensional limiting system to prevent the female connector and male connector from loosening and falling off due to external force. The bending strip at the bottom of the housing passes through the COME board and is fixed, which enhances the mechanical connection strength between the interface and the board and effectively delays wear and tear during long-term use.

[0029] The snap-fit ​​design of the spring contacts A and C with the male connector in the anti-dislodge plug-in interface not only prevents the male connector from falling off by increasing friction, but also optimizes electrical contact to reduce signal transmission loss and ensure stable data transmission. The snap-fit ​​structure of the housing buckle and the bending plate enables quick assembly and positioning during production, reduces production costs and facilitates later maintenance and replacement, so that the COME board can still maintain the stability and durability of the USB interface in complex scenarios such as frequent plugging and unplugging.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The following combination Figures 1 to 6 This application will be described in further detail.

[0039] This application discloses a COME board with multiple expansion interfaces. The COME board body 14 integrates a PCIe expansion module, a USB interface module, a storage interface module, a network interface module, a video output interface module, and a customized expansion interface module.

[0040] The PCIe expansion module includes one set of PCIe 3.0 x8 interface 1 and two sets of PCIe 2.0 x8 interfaces (which can be split into two x4 interfaces);

[0041] The USB interface module includes four USB 2.0 ports 3 and four USB 3.0 ports 4;

[0042] The storage interface module includes three SATA 3.0 interfaces.

[0043] The network interface module is equipped with two 10 / 100 / 1000Mb auto-sensing gigabit Ethernet ports.

[0044] The video output interface module includes an HDA interface 7, an HDMI interface 8, a VGA interface 9, and an LVDS interface 10;

[0045] The customized expansion interface modules include GPIO interface 11, LPC interface 12, and SPI interface 13.

[0046] PCIe interfaces, as high-speed data transmission interfaces, are widely used to expand various high-performance devices, such as graphics cards, high-speed network cards, and storage controllers. By providing such abundant PCIe interface resources, the needs of different users for high-speed data transmission and device expansion can be met. For example, in server applications requiring large-scale data processing, high-performance graphics cards can be expanded via PCIe interfaces to accelerate data processing, or high-speed network cards can be expanded to meet the network transmission requirements of large data volumes. In the field of industrial automation, PCIe interfaces can be used to connect high-speed data acquisition cards to achieve rapid acquisition and processing of various parameters on the production line.

[0047] It features four USB 2.0 ports and four USB 3.0 ports. USB interfaces are among the most widely used universal interfaces, capable of connecting various USB peripherals such as mice, keyboards, printers, cameras, and storage devices. The USB 2.0 ports (ports 3) meet the connection needs of devices with lower data transfer speed requirements, such as ordinary keyboards and mice; while the USB 3.0 ports (ports 4) offer higher transfer speeds, meeting the connection needs of devices with higher data transfer speed requirements, such as high-speed external hard drives and high-definition cameras. This combination of USB ports with different speeds satisfies diverse user device connection needs, improving the versatility and applicability of the COME board.

[0048] The motherboard provides three SATA 3.0 interfaces. SATA interfaces are primarily used to connect high-capacity storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs). With the ever-increasing demand for data storage, three SATA 3.0 interfaces can meet users' needs for large-capacity data storage and can be used to build local storage systems for storing large amounts of business data, multimedia files, etc. For example, in a video surveillance system, multiple high-capacity hard drives can be connected via SATA interfaces to store and manage long-duration video data.

[0049] Equipped with two 10 / 100 / 1000Mb adaptive gigabit Ethernet ports, these ports ensure stable network communication and high-speed data transmission, meeting the bandwidth requirements of various network applications. Whether for data transmission and file sharing in an enterprise network environment or for high-speed communication between devices in the Industrial Internet of Things (IIoT), the dual gigabit ports provide reliable network connectivity and also enable network redundancy, improving network reliability.

[0050] The system features an HDMI interface (7), an HDMI interface (8), a VGA interface (9), and an LVDS interface (10), supporting display output at a maximum resolution of 1920×1080. These rich video output interfaces meet the connectivity needs of various display devices and are suitable for a wide range of industrial and embedded display applications. For example, in industrial control, the VGA interface (9) can be used to connect to a traditional industrial monitor for equipment status monitoring and user interface display; in multimedia presentations, the HDMI interface (8) can be used to connect to a high-definition television or projector for high-definition image and video display; and the LVDS interface (10) is commonly used to connect to LCD screens, suitable for embedded devices with requirements for display quality and power consumption.

[0051] The customized expansion interface module provides the COME board with GPIO interface 11, LPC interface 12, and SPI interface 13, among others. GPIO (General Purpose Input / Output) allows users to implement more customized expansion and control functions according to their actual needs, such as connecting external sensors and controlling relays; the LPC (Low Pin 17 Bus) interface can be used to connect some low-speed devices, such as BIOS chips and I / O expansion chips; SPI (Serial Peripheral Interface) is commonly used to achieve high-speed serial communication with external devices, such as connecting Flash memory and sensors. These reserved interfaces provide users with more expansion possibilities, meeting the special needs of different industries and application scenarios.

[0052] The four USB 2.0 ports 3, four USB 3.0 ports 4, and two 10 / 100 / 1000Mb adaptive gigabit Ethernet ports 6 are located on the outside of the COME board 14 and close to the outer edge of the COME board 14 in an easily accessible position for user convenience.

[0053] One set of PCIe 3.0 x8 interfaces 1 and two sets of PCIe 2.0 x8 interfaces 2 are centrally mounted on the left side of the COME board 14, and their interference with other interfaces is reduced through reasonable wiring and shielding measures. The three SATA 3.0 interfaces 5 are located away from the power circuitry on the COME board 14 to avoid the impact of power supply noise on storage data transmission.

[0054] The COME board 14 supports 64-bit data width and 8 / 16-bit memory chips, allowing users to configure memory capacity according to their needs and meet the memory requirements of different application scenarios. For example, in applications with high memory requirements such as big data processing and virtualization, a large capacity of memory can be configured to improve system efficiency and data processing capabilities; while in cost-sensitive embedded applications, an appropriate capacity of memory can be configured according to actual needs, reducing costs while meeting performance requirements. In terms of interface layout, the COME board 14 places commonly used interfaces in easily accessible locations, and rationally isolates and arranges high-speed interfaces and interference-sensitive interfaces.

[0055] like Figure 2-6 As shown, both USB 2.0 interface 3 and USB 3.0 interface 4 adopt a non-detachable pluggable interface. The non-detachable pluggable interface includes a USB female connector 15 and a housing 16. The USB female connector 15 is inserted into the housing 16 and then encapsulated within it. Inserting and encapsulating the USB female connector 15 into the housing 16 forms a stable whole. When the USB plug of an external device is inserted into the female connector, the housing 16 provides additional support, effectively reducing the risk of the female connector loosening, shifting, or even falling off due to frequent plugging and unplugging or external pulling. The housing 16 enhances the mechanical strength of the entire USB interface. When faced with significant external force, such as accidental collision or squeezing, the housing 16 can disperse the force, preventing direct impact on the vulnerable parts of the USB female connector 15, preventing breakage of the female connector or breakage of the pins 17, and improving the durability of the interface.

[0056] The bottom of the housing 16 has a through hole 18 through which the pins 17 on the USB female connector 15 pass. The locking slot 19 on the USB female connector 15 is engaged with the bottom plate 20 on the bottom of the housing 16 and located in front of the through hole 18. This further positions the USB female connector 15 and prevents it from moving back and forth inside the housing 16. The engagement of the locking slot 19 with the bottom plate 20 increases the fixing points of the USB female connector 15 inside the housing 16, constraining the female connector from the bottom. This works in conjunction with the fixing structures of other parts of the housing 16 to make the entire USB interface structure more stable and less prone to deformation or damage when subjected to external forces.

[0057] The two side plates 21 of the housing 16 are provided with spring pieces B23 that engage with the limiting grooves 22 on the USB female connector 15.

[0058] The two side plates 21 of the housing 16 are respectively provided with two fastening blocks 24 arranged symmetrically at the top and bottom. The bending plates 25 on the left and right sides of the housing 16 are folded to the left and right side openings of the housing 16. The fastening positions 26 on the bending plates 25 cooperate with the fastening blocks 24 to achieve the encapsulation and positioning of the USB female connector 15.

[0059] The spring clips B23 on the two side plates 21 of the housing 16 engage with the limiting grooves 22 on the USB female connector 15, restricting the movement of the USB female connector 15 from the side and preventing it from wobbling left and right within the housing 16. When the device is subjected to vibration or external force during use, this limiting design ensures that the USB female connector 15 remains in the correct position, maintaining a good electrical connection. Two symmetrically arranged latches 24 on the side plates 21 of the housing 16 engage with the latches 26 on the bent plate 25, achieving rapid encapsulation and positioning of the USB female connector 15 within the housing 16. This design facilitates the installation and fixation of the USB female connector 15 into the housing 16 during production assembly, improving assembly efficiency. Moreover, compared to other complex fixing methods, the latching method is simpler to operate, reducing production costs and facilitating later repair and replacement of the USB interface. In mass production of COME boards, this easy-to-install and encapsulate design can significantly improve production efficiency and shorten the production cycle.

[0060] The front side of the casing 16 is provided with symmetrically arranged limiting plates 27 that limit the USB female connector 15 within the casing 16. The inner side of the two limiting plates 27 is provided with spring pieces A28 that clamp the male connector of the USB female connector 15. The front sides of the USB female connector 15 are provided with slots 29 that cooperate with the spring pieces A28 to limit and abut.

[0061] When the USB male connector of an external device is inserted into the female connector, the spring contact A28 firmly holds the male connector in place, increasing the friction between the male and female connectors and effectively preventing the male connector from accidentally falling off due to external pulling or device shaking. The slots 29 on both sides of the front end of the USB female connector 15, in conjunction with the spring contact A28, ensure that while holding the male connector in place, the spring contact A28 also makes better contact with it, guaranteeing the stability and reliability of signal transmission. The tight contact between the spring contact A28 and the male connector reduces contact resistance, lowers signal loss during transmission, and improves data transmission quality.

[0062] The bottom sides of the housing 16 are provided with two bending strips 30 that penetrate through the COME board 14 and fix the housing 16 to the COME board 14. This makes the connection between the USB interface and the COME board more stable and can withstand greater external forces without displacement or loosening. The bending strips 30 not only serve a fixing function, but also enhance the mechanical strength of the entire USB interface on the COME board.

[0063] The USB female connector 15 is provided with a plug block 32 for inserting a male connector in the plug slot 31. The upper and lower ends of the plug block 32 are respectively provided with spring pieces C33 that are engaged and positioned to fit the holes on the male connector.

[0064] The connector block 32 within the USB female connector 15's insertion slot 31 has spring contacts C33 at both ends that engage with the holes on the male connector for precise positioning. When the male connector is inserted into the female connector, the spring contacts C33 engage with the holes on the male connector, ensuring accurate positioning and preventing the male connector from shifting or wobbling within the female connector. This locking mechanism further enhances the connection strength between the male and female connectors, preventing the male connector from falling out and providing users with a more stable and reliable connection experience. The tight fit between the spring contacts C33 and the male connector's holes helps maintain good electrical contact between the male and female connectors, reducing interference and signal loss during transmission.

[0065] This multi-extension interface COME board achieves efficient expansion through modular integration and scientific layout. PCIe, USB, SATA, and other interfaces are distributed as needed, high-speed interfaces are centrally shielded to prevent interference, commonly used interfaces are externally mounted for easy plugging and unplugging, and memory can be flexibly configured. This design not only meets the high-performance requirements of server big data processing and industrial high-speed data acquisition, but also adapts to diverse scenarios through network redundancy and multiple display interfaces. Customized interfaces further provide expansion possibilities for specific industry needs.

[0066] The USB interface adopts an anti-dislodgement plug-in structure to enhance connection reliability: the female connector is encapsulated in the housing 16 to form a stable whole. The bottom through hole 18 and the locking position 19, the side plate 21 spring piece B23 and the limiting groove 22, and the front limiting plate 27 and the spring piece A28 work together to limit and fix the female connector and the male connector from the front, back, left and right sides to prevent loosening and falling off due to external forces; the bending strip 30 penetrates the board to fix the housing 16, enhances the mechanical strength of the interface and the COME board, and delays wear and tear during long-term use.

[0067] The snap-fit ​​design of spring A28, spring C33 and male connector not only increases friction to prevent male connector from falling off, but also optimizes electrical contact to reduce signal loss and ensure stable data transmission. The snap-fit ​​structure of housing 16, buckle 24 and bending plate 25 enables rapid positioning in production assembly, reduces costs and facilitates maintenance and replacement, allowing the COME board to maintain interface stability and durability in scenarios such as frequent plugging and unplugging.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
