[0044] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0045] like Figure 1 and Figure 2 As shown, this application provides a box structure, including a box frame 1 and pairs of supports installed inside the box frame 1. The box frame 1 specifically includes a U-shaped top cover and a straight bottom plate. The supports include a first support 2 and a second support 3, wherein the first support 2 is located above the second support 3, and the two are arranged facing each other. Both the first support 2 and the second support 3 are provided with guide rails for inserting circuit boards. The two ends of the circuit board are respectively inserted into the guide rails of the first support 2 and the second support 3, thereby achieving rapid installation and stable fixation of the circuit board. In particular, the guide rails of the first support 2 and the second support 3 are integrally integrated with their respective supports. This integrated design not only significantly enhances the overall strength and stability of the supports but also simplifies the manufacturing process, reduces production costs, and avoids installation deviations or loosening problems caused by weak connections between the guide rails and supports.
[0046] The enclosure frame 1 and supports are both formed from galvanized steel sheets through cutting, punching, and bending processes, resulting in a simple structure that is easy to manufacture. All parts are connected and fixed using rivets, making the assembly process simple and efficient, ensuring the high strength and reliability of the overall structure. Furthermore, the entire assembly surface is powder-coated, which not only enhances the appearance but also strengthens the enclosure's protective performance, enabling it to adapt to various complex environments.
[0047] The front faces of the first support 2 and the second support 3 are respectively provided with a series of flanged and tapped fixing holes for mounting and fixing the microcomputer protection motherboard PCB; the rear faces are also provided with fixing holes for fixing the microcomputer protection insert plate 9, thereby ensuring the stable installation of the circuit board and other functional modules. The front ends of the top cover and the bottom plate are stamped with bend edges. After the panel is installed, it is nested into the bend edges, which not only improves the installation accuracy of the panel, but also enhances the overall electromagnetic compatibility (EMC) performance of the chassis. In addition, the rear face of the top cover is equipped with a frame grounding screw, which provides reliable protective grounding for the whole machine, further improving the safety and anti-interference capability of the equipment. The second support 3 is also affixed with a guide rail serial number film to indicate the guide rail position, making it easy for the circuit board to identify the corresponding guide rail.
[0048] In one specific embodiment of this application, the support has at least two through holes 4, and a flange 5 is formed circumferentially around each through hole 4. The flanges 5 on adjacent sides between the two through holes 4 together form a guide rail structure for guiding the installation of the circuit board. The flanges 5 are integrally formed with the support during the stamping process of the through holes 4. This integral forming design not only improves the structural strength and precision of the guide rail, but also simplifies the manufacturing process and avoids assembly errors or loose connections that may occur due to separate installation of the guide rail. In addition, the stamping process of the flanges 5 ensures a seamless connection between the guide rail and the support, further enhancing the stability and durability of the overall structure.
[0049] In one specific embodiment of this application, there are multiple guide rails, which are arranged parallel to each other and at uniform intervals along a straight line. The spacing between each guide rail corresponds to the thickness of the circuit board assembly inserted on it, so as to arrange and install the plug-in boards of different functions (power supply, CPU, I / O, AC acquisition, communication, etc.) of the microcomputer protection device.
[0050] This application also provides a chassis, including a liner assembly and the chassis structure described in the above embodiments, wherein the liner assembly is connected to the chassis structure. A circuit board is mounted on the liner assembly. Since this liner assembly has the chassis structure described in the above embodiments, it also possesses the advantages of the chassis structure described in the above embodiments.
[0051] To address the issues of a single chassis structure and poor usability, the chassis structure of this application can be configured into three different chassis structures based on different panel assembly methods.
[0052] like Figure 3 and Figure 4 As shown, in a specific embodiment of this application, for use scenarios where no LCD display or human-computer interaction interface is required, the chassis includes a liner assembly, a cover plate 6, and the enclosure structure described in the above embodiment. The circuit board is mounted on the liner assembly and connected to the front opening of the enclosure structure via the liner assembly, thereby securing the circuit board. The cover plate 6 is connected to the rear opening of the enclosure structure to seal the enclosure structure and ensure the safe operation of the internal components.
[0053] like Figure 7 and Figure 8As shown in a specific embodiment of this application, for use scenarios requiring LCD displays or human-computer interaction interfaces, the chassis adopts a front-mounted plug-in installation method to meet users' needs for convenient operation and functional expandability. The chassis also includes an interactive panel 7, a panel film, a dust plug for the debugging port, an LCD PCB cover, and interactive panel brackets 8 located on both sides of the chassis frame 1. The interactive panel brackets 8 are fixedly connected to the chassis frame 1 with screws, providing stable support for the interactive panel 7. The interactive panel 7 is located on the front open side of the chassis structure and is rotatably connected to the interactive panel bracket 8 to achieve flexible adjustment of the operating angle. Specifically, the interactive panel 7 is equipped with two panel hinges, which are fixed to the interactive panel 7 with screws. After installation, the upper end of the hinge extends into the hinge hole of the left interactive panel bracket 8, thereby realizing the rotatable function of the interactive panel 7. Two captive screws are provided on the right side of the interactive panel 7, which can be connected to the fixing holes on the right interactive panel bracket 8 to ensure the stability of the interactive panel 7 in the fixed state. A panel film is affixed to the interactive panel 7, serving as the overall interface and providing clear operation instructions and information display. Dust plugs for the debugging ports are installed on the panel's debugging ports, working in conjunction with the panel film to significantly improve the overall IP protection level of the panel, effectively preventing the intrusion of dust and foreign objects and ensuring reliable operation of the equipment in complex environments. A series of nuts and posts are riveted to the back of the interactive panel 7 for mounting the LCD PCB board of the microcomputer protection device, ensuring a stable installation of the LCD display module. Simultaneously, a protective cover for the LCD PCB board is also provided on the back of the interactive panel 7, fixed to the front panel by screws and LCD PCB board fixing posts, further enhancing the electromagnetic compatibility (EMC) shielding effectiveness of the LCD PCB board and reducing the impact of external electromagnetic interference on the equipment. In addition, a grounding stud is provided on the back of the interactive panel 7, which, through connection with the grounding stud on the left interactive panel bracket 8, achieves reliable grounding of the LCD PCB board, further improving the safety and stability of the equipment. The left and right interactive panel brackets 8 and the cover plate 6 are all fixed to the housing frame 1 with screws, ensuring the stability and consistency of the overall structure.
[0054] like Figure 5 and Figure 6As shown in a specific embodiment of this application, the chassis is designed for use scenarios requiring LCD display and human-computer interaction, such as secondary protection cabinets. The chassis employs a rear-mounted plug-in design, with an integrated LCD display interface on the front panel to meet human-computer interaction needs. The chassis includes an interactive panel 7, which is connected to the front opening of the chassis structure, while the liner assembly is connected to the rear opening, forming a complete closed structure. The interactive panel 7 consists of an interactive panel film, a flange bracket, and a dust plug for the debugging port. The interactive panel 7 and the flange bracket are fixed to the chassis frame 1 with screws, and the flange bracket is used to connect to an external mounting base. The interactive panel film is affixed to the interactive panel 7, serving as the interactive interface for the entire device, providing clear operation instructions and information display. The dust plug for the debugging port is installed on the panel's debugging port, working together with the interactive panel film to significantly improve the overall IP protection level of the panel, effectively preventing the intrusion of dust and foreign objects. Furthermore, a series of nuts are riveted to the back of the interactive panel 7 for mounting the LCD PCB board of the microcomputer protection equipment, ensuring the stable installation and reliable operation of the LCD display module.
[0055] like Figure 9 As shown in one specific embodiment of this application, the liner assembly includes multiple liner plates 9 sequentially spliced together. The width of each liner plate 9 corresponds to the thickness of the circuit board assembly inserted onto it, ensuring that the circuit board assembly can be accurately installed and securely fixed. The liner assembly consists of insert liner plates 9 of different widths. Each liner plate 9 is formed by bending galvanized steel sheet, which has high structural strength and corrosion resistance. Two non-removable screws are press-fitted onto the liner plate 9, which are used to fix it to the frame assembly, ensuring the stability and reliability of the liner plate 9 inside the housing. Each liner plate 9 has two bent edges, one of which has two press-fit studs for installing the insert PCB, providing stable support and electrical connection; the other side has a series of rectangular openings for installing three-section beryllium copper springs. Through the conductive contact between the beryllium copper springs and adjacent liner plates 9, a continuous electromagnetic shielding path is formed, thereby effectively improving the electromagnetic compatibility (EMC) shielding performance of the whole machine and reducing the impact of external electromagnetic interference on the operation of the equipment.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
