Description

Technical Field

[0001] This utility model relates to the field of electronic equipment chassis technology, and more specifically, to a modular integrated chassis for I / O equipment in rail transit vehicles. Background Technology

[0002] Rail transit vehicles, such as subways, light rail, and high-speed trains, rely heavily on various input / output (I / O) devices for their operation control, status monitoring, and passenger information systems. These I / O devices are responsible for collecting status signals from various parts of the vehicle (such as door opening / closing status, speed signals, and fault signals) and outputting control commands (such as lighting control and broadcast triggering), making them a key component in ensuring the safe, reliable, and efficient operation of trains.

[0003] Traditional rail transit vehicle I / O equipment typically employs a distributed layout, where various functional I / O boards, power modules, communication modules, etc., are independently installed in different electrical cabinets within the vehicle. This architecture has significant drawbacks: First, the connections between modules require a large number of complex cables, resulting in cumbersome vehicle wiring, increased space consumption, and added weight, and hindering troubleshooting and maintenance; second, the dispersed nature of the modules leads to low overall system integration, which is detrimental to functional expansion and unified management.

[0004] To improve integration, some chassis solutions have emerged that centrally install I / O modules. However, existing integrated chassis still have many shortcomings. On the one hand, the internal structure of most chassis is fixed, and the installation position and number of various functional boards (such as power boards, communication boards, digital I / O boards, analog I / O boards, etc.) lack flexibility, making it difficult to quickly customize and adjust according to the functional requirements of different vehicles or systems. On the other hand, the connection methods between the boards and the chassis backplane (or motherboard), as well as the fixing methods of the boards themselves, are often quite complex, making it inconvenient for on-site installation, replacement, or maintenance. When a board fails, the disassembly and replacement process is cumbersome and may affect the availability of the entire system.

[0005] Therefore, this utility model provides a modular integrated chassis for I / O equipment in rail transit vehicles, which can solve the technical problems of low integration, poor flexibility and inconvenient maintenance in the prior art, thereby optimizing the integration and flexibility of the chassis and facilitating maintenance.

[0011] In the above structure, the chassis motherboard is provided with several fixed connectors, which are respectively plugged and plugged into the power supply board, Ethernet board, MCU board, VIO board, DIO board and DI board.

[0012] In the above structure, the modular integrated chassis for rail transit vehicle IO equipment includes fixing bolts. The power supply board, Ethernet board, MCU board, VIO board, DIO board, and DI board have a first mounting hole at the edge of the end away from the chassis motherboard. The plug-in board has a second mounting hole on both sides. The chassis body has a third mounting hole on both sides of the opening. The fixing bolt passes through the first mounting hole, the second mounting hole, and the third mounting hole in sequence.

[0013] In the above structure, heat sinks are also fixedly installed on both sides of the main body of the chassis. The heat sinks are provided with a number of heat dissipation holes, which are arranged in an array.

[0014] In the above structure, handles are fixedly installed at both ends of the opening of the main body of the chassis. The handles include a handle and a handle plate. The handle plate is fixedly connected to the main body of the chassis, and the handle is fixedly connected to the handle plate.

[0015] The beneficial effects of this utility model are as follows: By connecting both the external interface board group and the I / O board group to the motherboard of the chassis through a plug-in connection, the present utility model integrates both into the main body of the chassis. Compared with the distributed layout of the prior art, this solution has a higher degree of integration. Furthermore, since both the external interface board group and the I / O board group are plug-in connected to the motherboard of the chassis, the chassis can be configured with various boards according to different needs, so as to ensure the flexibility of chassis configuration. When some boards in the external interface board group and the I / O board group fail and need to be repaired or upgraded, only the corresponding boards need to be removed from the main body of the chassis for maintenance, without the need to maintain the entire chassis. Therefore, this utility model can optimize the integration and flexibility of the chassis and facilitate maintenance. Attached Figure Description

The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] Reference Figure 1 As shown, this utility model discloses a modular integrated chassis for I / O equipment in rail transit vehicles, comprising: The main body of the chassis is recessed, and the motherboard is fixedly installed inside the main body of the chassis. A plug-in board is fixedly installed at the opening of the main body of the chassis. The plug-in board has several rectangular holes, which are arranged parallel to each other.

The chassis motherboard inside the main chassis integrates a bus shared by all boards, enabling electrical interconnection and information exchange between various functional boards. The plug-in board provides standardized and flexible plug-in holes for each board through standardized, parallel rectangular holes, providing positioning and fixing for the assembly of each board with the chassis motherboard. The external interface board group and I / O board group, as functional modules of the chassis, connect external devices to the chassis motherboard via signal connection lines to achieve data exchange between the chassis and external devices. In the specific implementation of this utility model, the modular integrated chassis for rail transit vehicle I / O equipment integrates both the external interface board group and the I / O board group into the chassis main body by plugging and unplugging them to the chassis motherboard. Compared with the distributed layout of the prior art, this solution has a higher degree of integration. Moreover, since both the external interface board group and the I / O board group are plugged and unplugged to the chassis motherboard, the chassis can be configured with various boards according to different needs, so as to ensure the flexibility of chassis configuration. When some boards in the external interface board group and the I / O board group fail and need to be repaired or upgraded, only the corresponding boards need to be removed from the chassis main body for maintenance, without the need to maintain the entire chassis. Therefore, this utility model can optimize the integration and flexibility of the chassis and facilitate maintenance.

The VIO boards, DIO boards, and DI boards all pass through rectangular holes and are plugged into and connected to the motherboard of the chassis. The VIO boards and DIO boards are distributed between adjacent DI boards, and the DI boards closer to the middle of the plug-in board are closer to the MCU board.
