Technical Field

[0001] This utility model relates to the field of chassis technology, specifically to a standard chassis device for shipborne quick-install plug-in modules. Background Technology

[0002] Shipborne electronic equipment enclosures, as key physical carriers of shipboard electronic systems, are important infrastructures that ensure the stable operation of various communication, navigation, and control electronic equipment in complex marine environments.

[0003] Existing shipboard electronic equipment enclosures mostly adopt a fixed mounting structure, with plug-in modules secured by screws or clips. This type of structure presents the following problems in harsh environments such as ship vibration, humidity, and salt spray: Inconvenient maintenance: Disassembly requires tools and is time-consuming, making it difficult to meet the needs of rapid maintenance of ship equipment; Poor vibration resistance: Fixed connections are prone to poor contact due to vibration, affecting equipment stability; Insufficient sealing: Traditional chassis have weak moisture and salt spray protection capabilities, which can easily lead to circuit corrosion; Low space utilization: The modularity is low, making it difficult to adapt to the narrow space layout of ships.

[0004] To address this, a standard chassis device for quick-installation plug-in modules on a ship is proposed. Utility Model Content

[0019] like Figure 1 , Figure 2 As shown, a standard chassis device for shipborne quick-install plug-in modules includes: The small chassis 8 has multiple sets of guide rails inside. The guide rails are made of aluminum alloy and are plated with chemical nickel to improve corrosion resistance. The mounting backplate 10 is used to fix the plug-in module. It has mounting blocks 28 on both sides and is fixed by cross-slot countersunk screws 29. Standard Module 1, Standard Module 2, and Standard Module 3 are inserted into the small chassis 8 via guide rail slots. The tail of the module is pre-fixed by non-removable screw 7, and locked by non-removable screw 22 after insertion to prevent loosening due to vibration. The locking mechanism, including a snap ring 25 and a pull-out aid 26, is installed on both sides of the module body 13. Rotating it outwards can drive the module to quickly detach. The sealing structure, including the second sealing strip 9 on the bottom cover plate 6, the third sealing strip 12 on the module side plate 11, the fourth sealing strip 14 on the module panel 16, and the first sealing strip 4 on the outside of the bottom cover plate 6, can effectively isolate moisture and salt spray, and absorb high-frequency vibrations during ship operation, ensuring the contact stability of the plug-in module. The synergistic effect of the four-level sealing allows the equipment to maintain a high level of waterproofing even in the harsh environment of a ship.

[0020] Standard module 1, standard module 2, and standard module 3 are inserted along the guide rails of the small housing 8 and installed at the mounting position on the mounting backplate 10, locked by non-removable screw 22. The first sealing strip 4, the second sealing strip 9, the third sealing strip 12, and the fourth sealing strip 14 work together to resist vibration and moisture in the marine environment. The pull-out aid 26 rotates outward to drive the module body 13 to quickly detach from the small housing 8, achieving rapid module unlocking.

[0021] The guide rails use a standard 19-inch width, supporting a compact layout of multiple modules. The standardized design allows for parallel installation of multiple modules, reducing the equipment size compared to traditional solutions and significantly improving the utilization rate of limited space on ships.

[0022] The locking mechanism also includes a snap ring screw 23, an open retaining ring 24, and an external hexagonal slotted bolt 27, forming a lever-type unlocking structure. This lever mechanism requires less force to unlock a single module, can be completed without tools, and significantly reduces the workload of maintenance personnel.

[0023] The module panel 16 is fixed by a cross-slot countersunk screw 15 and is provided with a lamp cover 17 and a lamp block 18 for status indication. The lamp block 18 is fixed by a flat washer 19 and a cross-slot pan head screw 20. The lamp cover 17 covers the lamp block 18 by a cross-slot pan head combination screw 21.

[0024] The bottom cover plate 6 is secured by Phillips head countersunk screws 5, and the module side plate 11 is connected to the mounting block 28 by Phillips head countersunk screws 29. This modular connection structure reduces the time required to replace individual modules without affecting the operation of adjacent modules, significantly improving system availability.

[0025] The non-removable screw 7 is pre-fixed at the rear of the module, and the non-removable screw 22 locks the front of the module. This dual-locking design ensures that the module maintains a reliable connection even under marine vibration conditions, thereby reducing the failure rate.

[0026] In summary, this utility model, through its plug-in design, allows for quick assembly and disassembly without tools, reducing module replacement time by over 70% and facilitating rapid maintenance. The synergistic sealing of four-level sealing strips, combined with the modular enclosure structure, achieves excellent moisture resistance, withstands 95% humidity and salt spray environments, and offers superior shock resistance, ensuring stable operation of the equipment within the enclosure in the harsh environment of a ship. The standardized design supports a compact multi-module layout, adapting to the limited space of a ship and improving space utilization.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
