Description

Technical Field

[0001] This utility model relates to the technical field of industrial control computers, and in particular to a flexible and expandable industrial control device. Background Technology

[0002] An industrial personal computer (IPC) is a general term for a tool that uses a bus structure to detect and control production processes, electromechanical equipment, and process equipment.

[0003] With the rapid development of technology, industrial PCs are trending towards miniaturization. Most mainstream compact fanless embedded industrial PCs currently employ a highly integrated design. This integrated motherboard design approach leads to structural design that only considers the installation requirements of the existing motherboard, neglecting structural compatibility and scalability. However, when industrial PCs face various complex and changing industrial application scenarios, customer requirements for product functionality and interfaces vary, making it difficult for traditional industrial PC products to fully meet all customer needs. In such cases, industrial PCs require redesigns. However, even changing just one interface connector type in an integrated product design involves altering the entire motherboard and structure. This not only increases R&D costs but also requires significant time, delaying product launches. Utility Model Content

[0049] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model are further described in detail below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] Compact fanless embedded industrial PCs are ruggedized computers designed specifically for industrial environments. They feature compact structure, fanless operation, low power consumption, and high reliability. They are generally smaller than ordinary industrial PCs, making them easier to install and deploy, and suitable for space-constrained industrial environments.

[0053] As the background technology indicates, with the rapid development of technology, industrial PCs are trending towards miniaturization. Most mainstream compact fanless embedded industrial PCs currently employ a highly integrated design, integrating the CPU (Central Processing Unit), memory, storage, other functional circuits, and interface circuits onto one or two motherboards. However, this integrated motherboard design approach leads to structural design that only considers the installation requirements of existing motherboards, neglecting structural compatibility and scalability. Limited by the integrated motherboard design, the various functional interface circuits are highly integrated, making product functions fixed to the motherboard. When industrial PCs face various complex and changing industrial application scenarios, customer requirements for product functions and interfaces vary, making it difficult for traditional industrial PC products to fully meet all customer needs. Furthermore, because the structural design did not consider modularity, when product requirements necessitate changes to interfaces, the industrial PC requires modifications to the original design. However, even modifying a single interface connector in an integrated product design involves altering the entire motherboard and structure. This includes schematic design, PCB prototyping, structural design, prototype fabrication, and prototype debugging. This not only increases R&D costs but also consumes significant time, delaying product launch. Moreover, during after-sales repairs, when the product cannot be repaired by replacing parts, the entire motherboard must be replaced, further increasing repair costs.

[0054] In view of this, this embodiment provides a flexible expansion industrial control device, whose internal circuit board adopts a modular design to allow the industrial control computer to quickly adjust the resource scale and configuration according to the actual application needs, thereby improving the system's elasticity, availability and flexibility, reducing resource waste and cost expenditure, and solving the problem that the aforementioned industrial control computer cannot meet the usage needs of different application scenarios.

[0055] Please refer to the instruction manual attached. Figures 1-5The flexible extended industrial control equipment includes an outer casing 10, which serves as the supporting foundation for the equipment. The casing has a hollow accommodating cavity 11 for housing, protecting, and facilitating the carrying and transportation of the equipment. It is understood that, in order for the outer casing 10 to provide the aforementioned functions, it generally needs to be made of relatively high-strength materials, such as aluminum alloy or stainless steel. However, in some embodiments, the outer casing 10 is not limited to materials such as wood or plastic; the appropriate material should be selected based on the specific usage environment and requirements.

[0056] Furthermore, this embodiment does not impose strict limitations on the specific structural form of the device housing 10, which can be, but is not limited to, a cube, cuboid, cylinder, or other irregular shapes.

[0057] Based on the above-mentioned basic structure, the flexible extended industrial control equipment also includes a motherboard 20 and a core board 30.

[0058] The motherboard 20 provides a corresponding installation location for the core board 30. In addition to bringing out the resources of the core board 30, it can also integrate some commonly used interfaces of industrial control equipment, such as USB interface (Universal Serial Bus), display interface, debugging interface, network port, etc., according to different CPU platforms, for connecting and integrating various computer hardware components.

[0059] Specifically, the motherboard 20 can be fixedly mounted to the device housing 10 and located within the accommodating cavity 11 via mounting components. The motherboard 20 has a first surface 21 and a second surface 22 facing away from each other. Both the first surface 21 and the second surface 22 can be used to provide corresponding mounting positions for the core board 30 and expansion boards with functional expansion capabilities. It can be understood that the first surface 21 and the second surface 22 generally refer to the two larger, facing away surfaces of the motherboard 20. Taking the case where the motherboard 20 is placed horizontally within the accommodating cavity 11 as an example, when the first surface 21 is the upper surface of the motherboard 20, the second surface 22 is the lower surface of the motherboard 20; conversely, when the first surface 21 is the lower surface of the motherboard 20, the corresponding second surface 22 is the upper surface of the motherboard 20.

[0060] In this embodiment, the first surface 21 is provided with a board-to-board connector (not shown). Board-to-board connectors are electronic components that can connect different circuit boards together. Board-to-board connectors not only facilitate the disassembly and assembly of circuit boards, but also have the strongest transmission capacity among all connector types. Therefore, the motherboard 20 is detachably installed with the core board 30 using the board-to-board connector, so that the core board 30 is located on the first surface 21 of the motherboard 20. This allows the data transmission rate between the core board 30 and the motherboard 20 to meet the requirements of industrial control equipment, and also makes the core board 30 easy to disassemble and replace from the motherboard 20.

[0061] Furthermore, the second surface 22 is provided with a first high-speed connector 221 and a first low-speed connector 222 spaced apart from each other. The low-speed connector (including the first low-speed connector 222, the second low-speed connector 221, and the third low-speed connector 222) is a connector used for low-speed signal transmission, generally connecting low-speed expansion cards with low data transmission rate requirements. It is relatively inexpensive and easier to design and manufacture. The high-speed connector (including the first high-speed connector 221 and the second high-speed connector 221) is a connector capable of maintaining stable transmission performance under high-frequency signals. It has a higher transmission speed and is used to connect high-speed expansion cards with higher data transmission rates.

[0062] Understandably, low-speed connectors generally use plug and socket connections, and their form is relatively simple, possibly including pin header connectors, female header connectors, board connectors, terminal connectors, and card connectors. High-speed connectors, on the other hand, generally use on-board connections, socket connections, and wire harness connections, and their form is more complex, possibly including high-speed pin connectors, high-speed board-to-board connectors, and high-speed cable connectors.

[0063] For example, the low-speed connector in this embodiment can be used to implement interface functions such as RS485, RS232, CAN, ADC, and DIDO, while the high-speed connector can be used to implement functions such as 4G / 5G wireless communication, multi-channel Ethernet expansion, SSD storage, WiFi wireless communication, and camera video input.

[0064] This flexible expansion industrial control equipment allows the core board 30 to be mounted on the motherboard 20 via board-to-board connectors. This allows the core board 30 to meet some simple industrial needs. Furthermore, the industrial control equipment can replace different models of the core board 30 on the motherboard 20 according to different usage requirements. The inclusion of a first high-speed connector 221 and a first low-speed connector 222 on the motherboard 20 enables the flexible addition or replacement of different models of expansion boards. This modular design allows for different combination methods to achieve flexible expansion, enabling the industrial control equipment to quickly adjust resource scale and configuration according to actual application needs, thereby improving system elasticity, availability, and flexibility, and reducing resource waste and cost expenditure.

[0065] The motherboard 20 uses its opposite first surface 21 and second surface 22 to provide corresponding connectors for the core board 30 and the expansion board, respectively. In addition to making more effective use of the heat dissipation channels in the device housing 10 for heat dissipation and improving the heat dissipation efficiency of the device, it also makes it easier for industrial control equipment to carry out wiring design in the accommodating cavity 11. In the scenario where the core board 30 is used in industrial control equipment, the device can flexibly adjust the position and wiring path of the expansion board as needed to adapt to different application requirements, make more effective use of the space in the device housing 10, and is conducive to the compact and miniaturized design of industrial control equipment.

[0066] In addition, with the high-speed connector and low-speed connector both positioned on the second surface 22 of the motherboard 20, the high-speed connector is specifically located at the edge of the second surface 22. This not only prevents interference between the expansion board (such as the high-speed expansion board 40) connected to the high-speed connector and the core board 30, but also makes it easier for the high-speed connector to connect to the expansion board. This allows the (high-speed) expansion board, when connected to the high-speed connector, to be selectively positioned on one side of the motherboard 20 forming the second surface 22 or adjacent to the motherboard 20. Furthermore, placing the high-speed connector close to the edge of the motherboard 20 keeps it as far away as possible from other electronic components and traces on the motherboard 20. This not only helps reduce signal interference during transmission but also makes more efficient use of space on the motherboard 20. Especially when designing compact industrial control equipment, placing the high-speed connector at the edge of the second surface 22 provides more configuration options for the low-speed connector, allowing for a larger number of low-speed connectors to be arranged on the motherboard 20. This enables the flexible expansion industrial control equipment to handle a wider range of different application scenarios.

[0067] Please continue to refer to the appendix. Figure 6This flexible extended industrial control equipment also includes a core board 30, which integrates the core processing capabilities of the industrial control equipment. The core board 30 typically integrates a CPU, memory, and storage devices. As described above, in this industrial control equipment, the motherboard 20 provides a platform for connecting and integrating various hardware components, while the core board 30 provides the processing capabilities of the industrial control equipment. The two are detachably connected via board-to-board connectors, jointly realizing the various functions of the industrial control equipment.

[0068] It should be understood that the core board 30 is detachably mounted on the first surface 21 of the motherboard 20 via a board-to-board connector. As can be seen from the above, when an expansion board is connected to the motherboard 20, the connection positions of the expansion board and the core board 30 on the motherboard 20 are staggered. Specifically, they can be located on two opposing surfaces of the motherboard 20, or one can be located on the surface of the motherboard 20 and the other on the adjacent side of the motherboard 20. This allows for modular design of the circuit board of the industrial control equipment, facilitating the expansion or reduction of functions of the industrial control equipment according to the actual application scenario. At the same time, this layout also helps to reduce interference and conflicts in the circuit design process of the motherboard 20, and improve the stability and reliability of the equipment.

[0069] Please refer to the instruction manual attached. Figures 2-5 As can be seen from the above, the motherboard 20, through a high-speed connector located on its second surface 22, can provide a high-speed interface for the expansion board to meet the needs of expansion components with high transmission rate requirements. Therefore, in this example, the flexible expansion industrial control equipment also includes a high-speed expansion board 40. The high-speed expansion board 40 can be divided into various models according to different functions to meet the needs of different application scenarios. For example, the high-speed expansion board 40 can, but is not limited to, implement 4G / 5G mobile communication expansion functions, WiFi & Bluetooth communication expansion functions, solid-state drive storage expansion functions, Ethernet port expansion functions, video input interface expansion functions, etc. In addition to the high-speed expansion board 40 with the above-mentioned functions, there are other types of high-speed expansion boards 40, such as PCIe (peripheral component interconnect express) expansion (for high-speed data transmission and storage), USB expansion (providing multiple USB interfaces to support various peripheral connections), HDMI input / output expansion (for the transmission and reception of high-definition video signals), etc. These high-speed expansion boards 40 have different functions and application scenarios. In actual application scenarios, the high-speed expansion board 40 can integrate several different expansion functions according to the corresponding requirements, and integrate different expansion functions according to different requirements, so that flexible expansion industrial control equipment can replace the high-speed expansion board 40 according to the requirements.

[0070] It should be noted that, in order for all high-speed expansion boards 40 capable of providing different expansion functions to be mounted on the motherboard 20 via the first high-speed connector 221, each high-speed expansion board 40 needs to be equipped with a second high-speed connector 41 that matches the first high-speed connector 221. The second high-speed connector 41 is detachably connected to the first high-speed connector 221. Furthermore, the dimensions and structure of each high-speed expansion board 40, as well as the positions of the connection structures on the high-speed expansion board 40 for connecting to the device housing 10 and / or the motherboard 20, are consistent to ensure that each high-speed expansion board 40 can be easily replaced while maintaining a stable connection with the motherboard 20 and the device housing 10.

[0071] Correspondingly, the high-speed expansion board 40 is also provided with at least one first expansion interface 42 to provide a high-speed expansion device to be connected to the high-speed expansion board 40.

[0072] Because the first high-speed connector 221 in this embodiment is located at the edge of the second surface 22 of the motherboard 20, therefore, as Figures 11-12 As shown, in this embodiment, the high-speed expansion board 40, when connected to the motherboard 20, can be located on the side of the motherboard 20 opposite to the first surface 21. Furthermore, the high-speed expansion board 40 is positioned opposite and spaced apart from the second surface 22, and is located above or below the motherboard 20 within the projection of the second surface 22. Alternatively, as... Figures 2-5 As shown, the high-speed expansion board 40 can also be set on one of the outer sides of the motherboard 20 (the adjacent side mentioned above). The high-speed expansion board 40 is located on one of the front, rear, left, and right sides of the motherboard 20 and is at the same horizontal height as the motherboard 20, outside the projection of the second surface 22. This flexible expansion industrial control equipment can select different layout strategies according to actual usage needs, thereby improving the versatility of the equipment.

[0073] Similarly, please refer to the instruction manual appendix. Figures 2-5 As can be seen from the above, the motherboard 20 can provide a low-speed interface for the expansion board through a low-speed connector on its second surface 22, to meet the needs of expansion components with lower transmission rate requirements. Therefore, in this example, the flexible expansion industrial control equipment also includes a low-speed expansion board 50, which can be divided into various models according to different functions. The low-speed expansion board 50 is provided with a second low-speed connector 51 that matches the first low-speed connector 222. The low-speed expansion board 50 is detachably connected to the motherboard 20 through the second low-speed connector 51 and the first low-speed connector 222.

[0074] The low-speed expansion board 50 is equipped with a second expansion interface 52. This second expansion interface 52 can, but is not limited to, implement interface functions such as RS485, RS232, CAN, ADC, and DIDO. Furthermore, because industrial control equipment generally has a greater demand for low-speed expansion functions than high-speed expansion functions, the number of first low-speed connectors 222 on the motherboard 20 is generally not limited to one. Figure 10 As shown, the motherboard 20 can be equipped with multiple (two or more) first low-speed connectors 222, so that the flexible expansion industrial control equipment can expand or reduce the number of low-speed expansion boards 50 on the motherboard 20 according to the actual usage requirements of the low-speed expansion function.

[0075] Of course, to increase the number of low-speed expansion boards 50 on the motherboard 20, it is not necessarily necessary to have multiple first low-speed connectors 222 on the motherboard 20, for example, as shown in the attached... Figures 2-5 , Figure 11 In the embodiment shown, the motherboard 20 may have only one first low-speed connector 222 on its first surface 21, while a third low-speed connector 53 is also provided on the low-speed expansion board 50. The second low-speed connector 51 and the third low-speed connector 53 are respectively disposed on opposite sides of the low-speed expansion board 50 along the first direction, and the third low-speed connector 53 is configured to be detachably connected to the second low-speed connector 51.

[0076] In practical applications, taking multiple low-speed expansion boards 50 as an example, and only one first low-speed connector 222 on the main board 20, one low-speed expansion board 50 is connected to the first low-speed connector 222 of the main board 20 through its second connector. The other low-speed expansion boards 50 are connected to the second low-speed connector 51 on the previous low-speed expansion board 50 through their respective third low-speed connectors 53, so as to form multiple low-speed expansion boards 50 connected in sequence on the main board 20. This achieves the purpose of providing various low-speed expansion functions for flexible expansion industrial control equipment. This arrangement can reduce the space occupied by the first low-speed connector 222 on the main board 20, reduce the production cost of the main board 20, and improve its production efficiency. Furthermore, any two adjacent low-speed expansion boards 50 are connected through the second low-speed connector 51 and the third low-speed connector 53, which can also make the structure between the low-speed expansion boards 50 more compact, improve the space utilization rate in the accommodating cavity 11, and ensure that the second expansion interface 52 provided by the low-speed expansion board 50 can be set along its arrangement direction, which is convenient for the operator to use.

[0077] Of course, such as Figure 11 As shown, the third low-speed connector 53 and the second low-speed connector 51 provided on the low-speed expansion board 50 can also be provided on opposite sides of the low-speed expansion board 50 to change the arrangement direction between the low-speed expansion boards 50.

[0078] Furthermore, the low-speed expansion board 50 is provided with at least two second expansion interfaces 52. The at least two second expansion interfaces 52 are respectively located on opposite sides of the low-speed expansion board 50 along the second direction. It should be understood that the first direction and the second direction are perpendicular to each other on the same surface of the low-speed expansion board 50. In this way, interference between the low-speed expansion board 50 and the second expansion interfaces 52 can be avoided. When the low-speed expansion boards 50 are arranged along the length of the main board 20, the second expansion interfaces 52 of each low-speed expansion board 50 are respectively located on the front and rear sides of the main board 20, so that the operator can connect the external expansion device to the low-speed expansion board 50 through the front or rear side of the flexible expansion industrial control device.

[0079] As an optional implementation, based on the above-described flexible expansion industrial control equipment including the low-speed expansion board 50, such as... Figure 12 As shown, in order to connect multiple low-speed expansion boards 50 to the motherboard 20, taking the example of only one first low-speed connector 222 on the first surface 21 of the motherboard 20, the flexible expansion industrial control equipment also includes a low-speed expansion motherboard 60. The main function of the low-speed expansion motherboard 60 is to provide a connection interface with the motherboard 20 and allow multiple low-speed expansion boards 50 to be connected to it through connectors. The low-speed expansion motherboard 60 communicates and transmits data with the motherboard 20 through specific interfaces (such as slots, pins, etc.).

[0080] Specifically, the low-speed expansion motherboard 60 is provided with a fourth low-speed connector 61. The structure of the fourth low-speed connector 61 can be configured to be consistent with the second low-speed connector 51. The low-speed expansion motherboard 60 is detachably connected to the main board 20 through the fourth low-speed connector 61 and the first low-speed connector 222. The low-speed expansion motherboard 60 is provided with a plurality of fifth low-speed connectors 62 arranged in sequence. The fifth low-speed connectors 62 on the low-speed expansion motherboard 60 are used to detachably connect with the second low-speed connectors 51 on the low-speed expansion boards 50. By using the low-speed expansion motherboard 60 to provide multiple fifth low-speed connectors 62 on the main board 20 for multiple low-speed expansion boards 50, the need to set multiple first low-speed connectors 222 on the main board 20 can be eliminated, thereby reducing the production cost and process difficulty of the main board 20. Furthermore, the low-speed expansion motherboard 60 can provide operators with more operating space, allowing operators to easily expand or reduce the number of low-speed expansion boards 50 to meet specific application requirements.

[0081] This embodiment does not have specific limitations or requirements regarding the position of the low-speed template when connected to the motherboard 20, as long as it can ensure that the low-speed expansion motherboard 60 can still be accommodated in the receiving cavity 11 when the low-speed expansion board 50 is installed on it. For example, Figure 12As shown, with the high-speed expansion board 40 located on the side of the motherboard 20 forming the first surface 21, and spaced apart from and opposite to the first surface 21, the low-speed expansion motherboard 60 is located adjacent to the high-speed expansion board 40, parallel to the high-speed expansion board 40 and vertically offset from the motherboard 20. The fifth low-speed connector 62 disposed on the low-speed expansion motherboard 60 faces the direction of the low-speed expansion motherboard 60 closer to the motherboard 20, so that when the low-speed expansion board 50 is connected to the low-speed expansion motherboard 60, the low-speed expansion board 50 can be located adjacent to the motherboard 20, avoiding occupying too much height space.

[0082] As can be seen from the above, low speed and high speed can be determined based on actual usage needs. For example... Figure 6 As shown, the flexible expansion industrial control equipment in this embodiment only includes a motherboard 20 and a core board 30. The motherboard 20 and core board 30 form the basic combination of the flexible expansion industrial control equipment, providing the most basic functions. This combination can already meet the needs of some basic users. Furthermore, based on this, as... Figure 8 As shown, the flexible expansion industrial control equipment can add an appropriate number of low-speed expansion boards 50 according to the size of the equipment housing 10 to meet advanced requirements. In this embodiment, the flexible expansion industrial control equipment adds two low-speed expansion boards 50 to the motherboard 20 and core board 30. One low-speed expansion board 50 is connected to the motherboard 20 through a first low-speed connector 222 and a second low-speed connector 51, and the two low-speed expansion boards 50 are connected to each other through a second low-speed connector 51 and a third low-speed connector 53. Figure 7 As shown, this flexible expansion industrial control equipment adds a high-speed expansion board 40 to the motherboard 20 and core board 30. The high-speed expansion board 40 is connected to the motherboard 20 via a first high-speed connector 221 and a second high-speed connector 41 and is located adjacent to the motherboard 20, and is set on the same horizontal plane as the motherboard 20. Figure 2 As shown, this flexible expansion industrial control equipment employs both low-speed expansion boards 50 and high-speed expansion boards 40. Multiple low-speed expansion boards 50 are mounted on the upper side of the main board 20 and connected sequentially, while the high-speed expansion boards 40 are mounted on one side of the main board 20 along its length. In summary, through this free combination method, and by combining multiple models of the low-speed expansion boards 50 and high-speed expansion boards 40, this flexible expansion industrial control equipment can achieve hundreds of combinations, adapting to various market demands without requiring large-scale modifications and adjustments to the equipment's structure. This significantly reduces the cost of switching between application scenarios and improves the efficiency of the industrial control equipment in adapting to different usage scenarios.

[0083] Of course, in some implementations, such as Figure 10 As shown, a connector that can provide a connection to the low-speed expansion board 50 can also be provided on the high-speed expansion board 40.

[0084] As an optional embodiment of the above implementation, the first low-speed connector 222 is configured as a female header and the second low-speed connector 51 is configured as a pin header connector, which can provide high mechanical strength and reliability and meet the requirement of relatively low transmission rate. It is understood that when the low-speed expansion board 50 is disposed on the side of the motherboard 20 forming the first surface 21, and is spaced apart from and opposite to the first surface 21, the low-speed expansion board 50 and the motherboard 20 are at different horizontal heights. Therefore, the motherboard 20 and the low-speed expansion board 50 cannot be directly connected through the first low-speed connector 222 and the second low-speed connector 51. Therefore, a ribbon cable is also provided between the first low-speed connector 222 and the second low-speed connector 51.

[0085] Based on any of the above embodiments, the following provides a specific structural form of the device housing 10, such as... Figure 2 , 5 - Figure 9 As shown, the device housing 10 has an opening 131 that connects to the receiving cavity 11. The position of the opening 131 corresponds to the position of the core board 30. The opening 131 is configured to allow the core board 30 to pass through, so that the core board 30 can enter and exit the receiving cavity 11 through the opening 131 without disassembling the device housing 10, thereby realizing the disassembly and installation of the core board 30 with the motherboard 20.

[0086] When the device housing 10 is also provided with a high-speed expansion board 40, the size of the opening 131 on the device housing 10 can be set to extend to the position of the first expansion interface 42, or the opening 131 can be set to two, respectively corresponding to the positions where the core board 30 and the first expansion board are provided with the first expansion interface 42, so that the expansion device (such as a solid-state drive) provided on the high-speed expansion board 40 through the first expansion interface 42 can be installed and removed from the high-speed expansion board 40 through the opening 131.

[0087] Furthermore, a heat sink 12 is also provided on the device housing 10. The heat sink 12 covers the opening 131 and contacts the core board 30, thereby effectively transferring the heat generated by the core board 30 (CPU) and improving the heat dissipation efficiency of the industrial control equipment. At the same time, the heat sink 12 can be used as part of the device housing 10. In addition to providing heat dissipation for the core board 30, it can also protect the electronic components inside the housing 11, thereby extending the service life of the industrial control equipment. Moreover, when replacing the core board 30 and the expansion devices located on the high-speed expansion board 40, it is only necessary to remove the heat sink 12, allowing the core board 30 and the corresponding expansion devices to be replaced through the opening 131, thus facilitating the expansion and type switching of the flexible expansion industrial control equipment.

[0088] Please continue to refer to the appendix. Figures 1-8The device housing 10 includes a housing bracket 13 and a housing cover 14. The housing bracket 13 serves as the supporting base for the device housing 10 and is mainly used to provide the mounting position for the motherboard 20. When the motherboard 20 is connected to a high-speed expansion board 40 and the high-speed expansion board 40 is located adjacent to the motherboard 20, the housing bracket 13 is also used to support the high-speed expansion board 40. In addition, when the motherboard 20 is connected to a low-speed expansion board 50, at least one of the device housing 10, the motherboard 20, and the high-speed expansion board 40 can be connected to the low-speed expansion board 50 through a support column 17, thereby achieving stable assembly of the entire circuit board within the accommodating cavity 11.

[0089] In this example, the first surface 21 is defined as the upper surface of the motherboard 20, and the corresponding second surface 22 is defined as the lower surface of the motherboard 20. Therefore, the core board 30 is installed on the lower side of the motherboard 20 in actual application scenarios, and the housing bracket 13 is also located below the motherboard 20. To facilitate the disassembly and replacement of the core board 30 (and high-speed expansion devices), the opening 131 on the device housing 10 is opened in the housing bracket 13, and the housing cover 14 is placed on the upper side of the housing bracket 13, specifically on the side of the motherboard 20 used to form the first surface 21, opposite to the housing bracket 13, and enclosing each side of the motherboard 20. In this way, when the flexible expansion industrial control equipment needs to disassemble and replace the low-speed expansion board 50 and / or the high-speed expansion board 40, the housing cover 14 can be removed from the housing bracket 13 to provide replacement space for the corresponding expansion board. Thus, the replacement of the core board 30 and each expansion board can be achieved through different operation methods, avoiding mutual interference during disassembly and replacement, and effectively improving the operating efficiency of the flexible expansion industrial control equipment.

[0090] From the above, we can understand that, Figure 1 As shown in body 9, in one embodiment, when the flexible expansion industrial control equipment further includes a low-speed expansion board 50, and the low-speed expansion board 50 is provided with a second low-speed connector 51 that matches the first low-speed connector 222, and the low-speed expansion board 50 is detachably connected to the motherboard 20 through the second low-speed connector 51 and the first low-speed connector 222, the second expansion interface 52 provided on the low-speed expansion board 50 is located on the front and / or rear side of the accommodating cavity 11 when the low-speed expansion board 50 is connected to the motherboard 20.

[0091] like Figures 1-9As shown, the device housing 10 also includes a front panel 15 and a rear panel 16, which are detachably located on the front and rear sides of the device housing 10, respectively. The front panel 15 and / or the rear panel 16 have recesses corresponding to the second expansion interface 52, allowing the front panel 15 and the rear panel 16 to be matched with the second expansion interface 52 near the front and / or rear side of the device housing 10 through their respective recesses. Furthermore, when adjusting the number or changing the type of the low-speed expansion boards 50, the device housing 10 can maintain the position and shape of the recesses corresponding to the second expansion interface 52 on each low-speed expansion board 50 by replacing the corresponding type of front panel 15 and / or rear panel 16, thereby ensuring the integrity and aesthetics of the device housing 10.
