Description

Technical Field

[0001] This invention relates to the field of server racks, and in particular to a railway vehicle-mounted EMC server rack. Background Technology

[0002] With increasing competition in the high-speed rail sector, higher demands are being placed on the integration of signaling system equipment.

[0003] Signal system equipment is installed in cabinets. In the existing technology, on-board cabinets are usually made of welded integral frames, and some are equipped with shielding strips. However, with the increasing integration of signal systems, the original cabinets can hardly meet the requirements of highly integrated signal system equipment. For example, in the cabinet, the components are basically dependent on the main frame of the cabinet, and highly integrated signal system equipment often occupies the entire cabinet, which leads to the bus bundle being relatively crowded and unable to meet the installation requirements of the limited on-board space of the train. Summary of the Invention

[0004] The purpose of this invention is to provide a railway vehicle-mounted EMC cabinet.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A railway vehicle-mounted EMC cabinet includes a cabinet frame assembly, two side panel assemblies on two sides of the cabinet frame assembly, a front door assembly on the front of the cabinet frame assembly, a rear door assembly on the back of the cabinet frame assembly, and the cabinet also includes a top plate assembly on the top of the cabinet frame assembly and a bottom plate assembly on the bottom of the cabinet frame assembly.

[0007] The cabinet frame assembly has crossbars on both sides. The top plate assembly includes a top plate body, and a first cable tie, a second cable tie, a cable inlet hole, and a heat dissipation hole array on the upper surface of the top plate body. The cable inlet hole is provided with conductive foam. The two first cable ties are arranged in parallel, and the second cable tie is arranged perpendicular to the first cable ties. The two ends of the second cable tie are respectively fixed to the two first cable ties and their positions are adjusted along the axis of the first cable ties. The projection area of ​​the cable inlet hole on the plane of the top plate body is located between the projection areas of the two first cable ties on the plane of the top plate body. The heat dissipation hole array is covered with dustproof cotton.

[0008] The first wire tie is shaped like a "Z" to create a gap between the second wire tie and the main body of the top plate.

[0009] The conductive foam consists of two pieces. One end of one conductive foam is fixed to one side edge of the inlet hole, and the other conductive foam is set on one side edge of the inlet hole. The two conductive foams are spliced ​​together to form a rectangle, and the length of the seam is equal to the length of the rectangle formed by splicing.

[0010] The heat dissipation holes in the heat dissipation hole array are hexagonal heat dissipation holes.

[0011] The lengths of the heat dissipation hole array and the inlet hole are equal.

[0012] The base plate assembly includes a base plate body and a cable outlet hole, and the cable outlet hole is covered with a dustproof unit.

[0013] The dustproof unit includes a brush plate and a brush component disposed on the brush plate. The projection area of ​​the brush component on the plane where the main body of the plate is located completely covers the projection area of ​​the wire outlet hole on the plane where the main body of the plate is located.

[0014] The base plate body is also provided with grounding nails and fixing holes.

[0015] There are four crossbars, which are evenly distributed on the two sides of the cabinet frame assembly.

[0016] The cabinet also includes an L-bracket, which is mounted on the cabinet frame assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The frame-type load-bearing design improves the overall structural stability, reduces the impact and vibration during high-speed vehicle operation, and the installation of cable tie racks, dustproof cotton and conductive foam on the top plate can increase the cable distribution density, improve the space utilization inside the cabinet, and thus increase the overall cabinet capacity.

[0019] 2. The first wire tie frame is shaped like a "Z" to create a gap between the second wire tie frame and the main body of the top plate. This increases the height of the wire tie frame and the limited turning radius, which helps to reduce the stress on the incoming wires and reduce signal interference.

[0020] 3. It can provide stable installation and protection for internal equipment in complex environments such as vibration, impact and bumps during vehicle operation, ensuring normal operation of the equipment.

[0021] 4. It can effectively reduce the impact of external electromagnetic interference on the equipment inside the cabinet, and at the same time prevent electromagnetic radiation generated by the internal equipment from interfering with other systems of the vehicle.

[0022] 5. Ensure the equipment operates in a suitable temperature environment to extend its service life. Attached Figure Description

[0041] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0042] A railway vehicle-mounted EMC cabinet, such as Figure 1 As shown, the cabinet includes a cabinet frame assembly 1, two side panel assemblies 5 located on two sides of the cabinet frame assembly 1, a front door assembly 3 located on the front of the cabinet frame assembly 1, a rear door assembly 4 located on the back of the cabinet frame assembly 1, and the cabinet also includes a top plate assembly 2 located on the top of the cabinet frame assembly 1, and a bottom plate assembly 6 located at the bottom of the cabinet frame assembly 1.

[0043] Both sides of the rack frame assembly 1 are equipped with crossbars 7, such as Figure 3As shown, the top plate assembly 2 includes a top plate body 2-5, and a first wire tie 2-1, a second wire tie 2-2, a wire inlet hole, and a heat dissipation hole array disposed on the upper surface of the top plate body 2-5. The wire inlet hole is provided with conductive foam 2-4. The two first wire ties 2-1 are arranged in parallel, and the second wire tie 2-2 is arranged perpendicular to the first wire tie 2-1. The two ends of the second wire tie 2-2 are respectively fixed to the two first wire ties 2-1 and their positions are adjusted along the axial direction of the first wire tie 2-1. The projection area of ​​the wire inlet hole on the plane of the top plate body 2-5 is located between the projection areas of the two first wire ties 2-1 on the plane of the top plate body 2-5. The heat dissipation hole array is covered with dustproof cotton 2-3.

[0044] The frame-type load-bearing design improves the overall structural stability and reduces the impact and vibration during high-speed vehicle operation. Furthermore, by combining cable ties, dustproof cotton 2-3, and conductive foam 2-4 in the top plate, the cable distribution density can be increased, the space utilization inside the cabinet can be improved, and thus the overall cabinet capacity can be increased.

[0045] In this embodiment, the vehicle-mounted cabinet will experience strong impacts and vibrations during train operation. The cabinet typically employs special structural designs and installation methods, such as reinforcing ribs and buffer pads, to ensure the stability and reliability of the internal equipment. For example... Figure 2 As shown, the cabinet frame assembly includes shielding strips, frame welding, etc. The frame welding is formed by welding eight plugs and profiles. The profiles are bent into shape using a special process to ensure the load-bearing capacity and rigidity of the frame. Shielding strips are attached around the frame to ensure the conductivity between the cabinet frame and other components and improve the overall shielding effectiveness of the vehicle-mounted cabinet. The frame is designed with added reinforcing ribs and buffer pads to ensure the stability and reliability of the internal equipment.

[0046] Furthermore, in some embodiments, the first wire tie 2-1 is shaped like a "Z" to create a gap between the second wire tie 2-2 and the top plate body 2-5, thereby increasing the height of the wire tie and increasing the limited turning radius, which helps to reduce the stress on the incoming wires and reduce signal interference.

[0047] In addition, there are two conductive foam pieces 2-4. One end of one conductive foam 2-4 is fixed on one side edge of the inlet hole, and the other conductive foam 2-4 is set on one side edge of the inlet hole. The two conductive foam pieces 2-4 are spliced ​​together to form a rectangle, and the length of the seam is equal to the length of the rectangle formed by splicing.

[0048] In this embodiment, the heat dissipation holes in the heat dissipation hole array are hexagonal heat dissipation holes, and the length of the heat dissipation hole array and the inlet hole are equal.

[0049] like Figure 4As shown, the front door assembly 3 includes a linkage lock, ventilation holes, etc. The fixing method of the front door is crucial to the overall stability and safety of the vehicle-mounted cabinet. Considering the limited on-site construction space for the vehicle-mounted cabinet, this design adopts a detachable structure for the front door to ensure effective on-site construction space. In addition, reliable door linkage locks or fasteners will be provided to firmly secure the front door during vehicle movement and prevent accidental opening. The fixing device should undergo rigorous strength and durability testing to withstand the vibration and impact of the vehicle environment. To meet the heat dissipation requirements of the equipment inside the cabinet, ventilation holes are provided in the front door. The front door assembly of the cabinet has a certain degree of conductivity to ensure the shielding effectiveness of the cabinet.

[0050] like Figure 5 As shown, the rear door assembly 4 adopts a fixed design. The structural design should possess good rigidity to withstand vibrations and impacts during vehicle operation. The rear door assembly of the cabinet should have a certain degree of conductivity to ensure good overall conductivity of the cabinet and prevent static electricity and electromagnetic interference, thus ensuring the cabinet's shielding effectiveness.

[0051] like Figure 6 As shown, side panel assembly 5 adopts a fixed design. The structural design should have good rigidity to withstand the vibration and impact during vehicle operation. The cabinet side panel assembly has a certain degree of conductivity to ensure good overall cabinet conductivity and prevent static electricity and electromagnetic interference, thus ensuring the cabinet's shielding effectiveness.

[0052] like Figure 7 As shown, the base plate assembly 6 includes a base plate body 6-5 and a cable outlet hole. The cable outlet hole is covered with a dustproof unit, which includes a brush pressure plate 6-1 and a brush component 6-2 disposed on the brush pressure plate. The projection area of ​​the brush component 6-2 on the plane where the base plate body 6-5 is located completely covers the projection area of ​​the cable outlet hole on the plane where the base plate body 6-5 is located. The base plate body 6-5 is also provided with a grounding nail and a fixing hole 6-4. The cabinet also includes an L-bracket 9, which is disposed on the cabinet frame assembly 1.

[0053] In addition, there are four horizontal bars 7, evenly distributed on both sides of the rack frame assembly 1, such as... Figure 8 As shown, the crossbar includes the crossbar body 7-1 obtained by bending the entire plate and the first bending strip 7-2. The crossbar body 7-1 has multiple hollow parts 7-1-1 corresponding to the first bending strip 7-2. The vehicle cabinet is equipped with 4 crossbars on both sides of the cabinet frame to ensure that the cabinet has good rigidity and can withstand the vibration and impact during vehicle operation.

[0054] like Figure 9As shown, the vertical cable tray 8 at the cable inlet and outlet should ensure a smooth transition for the cables, avoiding sharp bends to prevent damage. When multiple cables are entering or exiting simultaneously, their order should be arranged logically to prevent crossing and confusion. The vertical cable tray is used to ensure the safety, stability, and neatness of the cables, improving the reliability and ease of maintenance of the cabinet.

[0055] like Figure 10 As shown, L-shaped brackets are typically designed according to the size and layout of the equipment. Use appropriate screws or fasteners to securely install the L-shaped brackets onto the inner wall of the cabinet, ensuring a stable installation capable of withstanding the weight of the equipment and vibrations from vehicle movement.

[0056] like Figure 11 As shown, the cable tie assembly is mainly used to organize and secure the cables in the vehicle-mounted cabinet, making the cable layout neat and orderly, avoiding cable tangling, and facilitating maintenance and management.

[0057] Vehicle-mounted cabinets experience strong impacts and vibrations during train operation. These cabinets typically employ special structural designs and installation methods, with reinforcing ribs and cushioning pads on the cabinet frame to ensure the stability and reliability of the internal equipment.

[0058] The train operating environment presents complex electromagnetic interference. The cabinet employs excellent electromagnetic shielding design and filtering measures to ensure normal equipment operation. It also possesses dustproof, waterproof, and corrosion-resistant properties to adapt to the harsh climatic conditions along railway lines. All components of the onboard cabinet ensure conductivity, enhancing the cabinet's shielding effectiveness and ensuring that the equipment inside is protected from external electromagnetic interference while minimizing its own electromagnetic radiation.

[0059] The train utilizes a modular design to achieve flexible configuration and rapid installation and maintenance within its limited onboard space, improving space utilization and scalability. The various functional modules of the onboard cabinet are easy to disassemble and replace, facilitating maintenance.
