Detailed implementation manners

[0029] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] The following will describe Figures 1 to 10 the wiring structure of the frame of the present invention.

[0031] As Figures 1 to 10 shown, the wiring structure of the frame provided by the embodiment of the present invention includes a high-voltage wire wiring assembly and a low-voltage wire wiring assembly.

[0032] Specifically, the high-voltage wire wiring assembly is used for threading high-voltage cables, and the low-voltage wire wiring assembly is used for threading low-voltage cables. Generally, the high-voltage wire wiring assembly and the low-voltage wire wiring assembly are distributed on both sides of the transverse direction of the frame, isolating the high-voltage cables and the low-voltage cables from both the structural and spatial aspects, which can avoid interference between the high-voltage cables and the low-voltage cables.

[0033] The transverse direction of the frame is the left-right direction of the frame, referring to Figure 1 the direction indicated by m. The longitudinal direction of the frame is the front-back direction of the frame, referring to Figure 1 the direction indicated by n. The frame includes a roof rack and a chassis 2. The transverse direction of the roof rack and the transverse direction of the chassis are both consistent with the transverse direction of the frame, and the longitudinal direction of the roof rack and the longitudinal direction of the chassis are both consistent with the longitudinal direction of the frame.

[0034] For the case where the high-voltage wires and low-voltage wires need to be cross-arranged, a cross-wire groove 21 needs to be provided on the frame. The cross-wire groove 21 is located at the position where the high-voltage wires and low-voltage wires cross. The cross-wire groove 21 has a high-voltage wire channel and a low-voltage wire channel, and both the high-voltage wire channel and the low-voltage wire channel are arranged along the transverse direction of the frame. The two ends of the high-voltage wire channel are respectively docked with the central wire grooves 1 corresponding to the high-voltage wires on both sides of the cross-wire groove 21, and the two ends of the low-voltage wire channel are respectively docked with the central wire grooves 1 corresponding to the low-voltage wires on both sides of the cross-wire groove 21.

[0035] Both the high-voltage wire wiring assembly and the low-voltage wire wiring assembly include a central wire groove 1, a distribution box 3, an end wire groove 4, a first wire pipe 5, and a vehicle-end cross-connection box 6. The central wire groove 1, the distribution box 3, the end wire groove 4, the first wire pipe 5, and the vehicle-end cross-connection box 6 are all arranged on the frame. For roof wiring, the central wire groove 1, the distribution box 3, the end wire groove 4, the first wire pipe 5, and the vehicle-end cross-connection box 6 are all arranged on the roof rack; for under-vehicle wiring, the central wire groove 1, the distribution box 3, the end wire groove 4, the first wire pipe 5, and the vehicle-end cross-connection box 6 are all arranged on the chassis 2 and are located below the chassis 2.

[0036] The central wire groove 1 is located in the middle part of the longitudinal direction of the frame and is used to provide a protection channel for the cables in the central area of the longitudinal direction of the frame. For under-vehicle wiring, the central wire groove 1 can be located between two bogies.

[0037] The distribution box 3 is located at the end of the central wire duct 1, and distribution boxes 3 are provided at both ends of the central wire duct 1. The distribution box 3 has a first wire passing port, a second wire passing port, and a third wire passing port, and the first wire passing port corresponds to the end of the central wire duct 1.

[0038] The end wire duct 4 is located on the side of the distribution box 3 away from the central wire duct 1. One end of the end wire duct 4 corresponds to the second wire passing port, and the other end of the end wire duct 4 extends towards the end of the vehicle frame.

[0039] One end of the first wire pipe 5 corresponds to the third wire passing port, and the other end of the first wire pipe 5 is used to extend towards the first target electrical appliance. The space between the distribution box 3 and the first target electrical appliance is narrow. By using the first wire pipe 5 to protect the cables in this space, it can adapt to the narrow space.

[0040] The vehicle-end cross-connect box 6 is located at the end of the vehicle frame, and the vehicle-end cross-connect box 6 corresponds to the end of the end wire duct 4.

[0041] The rail vehicle has multiple vehicle frames. The vehicle-end cross-connect boxes 6 located at the adjacent and closer ends of two vehicle frames are used to connect the cables of the two vehicle frames.

[0042] For one vehicle frame, the cable starts from the vehicle-end cross-connect box 6 at the first end of the vehicle frame and passes through the end wire duct 4 at the first end of the vehicle frame. The cable in the end wire duct 4 at the first end of the vehicle frame extends towards the distribution box 3 at the first end of the vehicle frame. At the position of the distribution box 3 at the first end of the vehicle frame, a part of the cable passes through the central wire duct 1 to extend towards the second end of the vehicle frame. Another part of the cable passes through the first wire pipe 5 at the first end of the vehicle frame and extends towards the first target electrical appliance. The cable in the central wire duct 1 extends to the distribution box 3 at the second end of the vehicle frame and merges with the cable in the first wire pipe 5 connected to the second end of the vehicle frame into the end wire duct 4 at the second end of the vehicle frame, and then connects to the vehicle-end cross-connect box 6 at the second end of the vehicle frame.

[0043] With such an arrangement, the cables located between the first end and the second end of the vehicle frame are all inside the vehicle-end cross-connect box 6, the end wire duct 4, the first wire pipe 5, the distribution box 3, and the central wire duct 1, achieving comprehensive protection of the cables of the vehicle frame, having a better protective effect on the cables, dust-proof and wind-sand-proof, effectively reducing the erosion of the external environment on the cables, reducing cable damage, extending the service life of the cables, and improving the safety and stability of the rail vehicle during storage and operation. Moreover, it makes the cable layout of the vehicle frame more concise and reliable.

[0044] In addition, in this embodiment, a combination of wire ducts and wire pipes is adopted. For positions with relatively spacious space, wire ducts are selected to protect the cables, and for positions with relatively narrow space, wire pipes are selected to protect the cables, which can well adapt to the space.

[0045] The above-mentioned vehicle frame can be a roof rack or a chassis rack. The wiring structures of the roof rack and the chassis rack 2 are similar, both using a central wire groove 1, a distribution box 3, an end wire groove 4, a first wire pipe 5, and a vehicle-end cross-connect box 6. The specific distribution positions are determined according to the structural layout of the roof rack and the chassis rack. The following takes the vehicle frame as the chassis rack 2 as an example for elaboration.

[0046] In the embodiment of the present invention, the central wire groove 1 includes a wire groove body 7, a wire groove cover 8, and a hanging earring 9.

[0047] The axis of the wire groove body 7 is arranged along the longitudinal direction of the chassis rack 2. An opening is provided on one side of the wire groove body 7 facing the chassis rack 2, and the opening extends from one end of the wire groove body 7 to the other end along the axis direction of the wire groove body 7. Through the opening, the cable can enter the wire groove body 7.

[0048] The wire groove cover 8 is arranged on the side of the wire groove body 7 close to the chassis rack 2, and the axis of the wire groove cover 8 is arranged along the longitudinal direction of the chassis rack 2. The wire groove cover 8 extends from one end of the wire groove body 7 to the other end. The wire groove cover 8 is used to cover the opening on the wire groove body 7 to protect the cable in the wire groove body 7.

[0049] The wire groove cover 8 is detachably connected to the wire groove body 7, which is convenient for maintenance and inspection.

[0050] The hanging earring 9 is looped around the side and bottom of the wire groove body 7, and both ends of the hanging earring 9 are used to connect to the chassis rack 2. While fixing the wire groove body 7 to the chassis rack 2, the hanging earring 9 can provide a supporting force to the wire groove body 7, which can improve the stability of the central wire groove 1.

[0051] Moreover, in the central wire groove 1 of this embodiment, the wire groove body 7 and the wire groove cover 8 can be first connected together to form a closed wire groove, and then fixed to the chassis rack 2 through the hanging earring 9. With such a setting, when threading the cable, the cable can be first threaded into the wire groove body 7 as required, and the wire groove cover 8 is connected to the wire groove body 7, and then the wire groove body 7 and the wire groove cover 8 are fixedly installed on the chassis rack 2 through the hanging earring 9. The cable can be threaded before fixing the wire groove body 7 to the chassis rack 2, which is convenient for operation.

[0052] In a specific embodiment, the detachable connection between the wire groove cover 8 and the wire groove body 7 can be realized by a clamping method, which is more convenient for disassembling and assembling the wire groove cover 8.

[0053] Specifically, an elastically deformable clamping protrusion can be provided on the wire groove body 7, and a clamping groove is provided on the wire groove cover 8. The clamping protrusion is adapted to the clamping groove. When the wire groove cover 8 is covered on the wire groove body 7, the clamping protrusion is exactly located in the clamping groove, thereby realizing the clamping connection between the wire groove cover 8 and the wire groove body 7.

[0054] In this embodiment, the wire duct cover 8 is provided with bending edges, which are arranged at both ends of the wire duct cover 8 along the transverse direction of the vehicle chassis 2. The bending edges extend along the outer side wall of the wire duct body 7 in a direction away from the vehicle chassis 2, that is to say, the bending edges extend along the outer side wall of the wire duct body 7 towards the bottom of the wire duct body 7.

[0055] The wire duct cover 8 not only covers the opening on the wire duct body 7, but also covers the edge of the opening, increasing the covering area of the wire duct cover 8 on the wire duct body 7.

[0056] In some embodiments, the inner wall of the wire duct body 7 and the side of the wire duct cover 8 facing the wire duct body 7 can be coated with insulating paint to prevent electromagnetic wave leakage.

[0057] In this embodiment, at least two hanging ear rings 9 are provided, and the hanging ear rings 9 are spaced apart along the axial direction of the wire duct body 7, and each hanging ear ring 9 is fixedly connected to the wire duct body 7.

[0058] Fixing the wire duct body 7 to the vehicle chassis 2 through multiple hanging ear rings 9 can improve the stability of the wire duct body 7.

[0059] Specifically, the fixed connection between the hanging ear ring 9 and the wire duct body 7 can be achieved by welding.

[0060] In this embodiment, the central wire duct 1 further includes a partition plate 10, and the partition plate 10 is arranged inside the wire duct body 7. The partition plate 10 can divide the internal space of the wire duct body 7 into at least two wire duct spaces for laying different types of cables, isolate the signal interference between different types of cables, and improve the electromagnetic shielding performance.

[0061] Specifically, the partition plate 10 is bent into an L shape. One bending edge of the partition plate 10 is fixedly connected to the bottom wall of the wire duct body 7, and the other bending edge of the partition plate 10 extends towards the opening direction of the wire duct body 7. The fixed connection between the partition plate 10 and the wire duct body 7 is achieved by welding.

[0062] Specifically, a partition plate 10 can be arranged in the central wire duct 1 of the high-voltage wire routing assembly to form two wire duct spaces, refer to Figure 8 . Two partition plates 10 can be arranged in the central wire duct 1 of the low-voltage wire routing assembly to form three wire duct spaces, as shown in Figure 7 .

[0063] In this embodiment, a first grounding seat 11 is arranged on the wire duct body 7, and the first grounding seat 11 can be connected to the vehicle chassis 2 through a grounding wire. A second grounding seat 12 is arranged on the wire duct cover 8, and the second grounding seat 12 can be connected to the vehicle chassis 2 through a grounding wire.

[0064] Such an arrangement realizes the grounding of the central cable duct 1, which can block the induced electric field and form a good electromagnetic compatibility electrical environment (called EMC electrical environment).

[0065] The grounding wire may be a flat grounding wire.

[0066] In this embodiment, the central wire duct 1 further includes a junction box 13 and a second wire threading tube 14 .

[0067] The junction box 13 is arranged on the side of the wire trough body 7 away from the vehicle bottom frame 2 . A wire threading hole is arranged on the side of the wire trough body 7 away from the vehicle bottom frame 2 . The junction box 13 corresponds to the wire threading hole and is fixedly connected to the wire trough body 7 .

[0068] The junction box 13 is provided with a branching hole, and the cables in the central wire duct 1 can be branched to the junction box 13 through the wire passing hole, and then pass out through the branching hole on the junction box 13.

[0069] One end of the second threading tube 14 is connected to the branch hole, and the other end of the second threading tube 14 is used to extend to the second target electrical appliance. The second threading tube 14 can protect the cables between the junction box 13 and the second target electrical appliance, and the protection is more comprehensive. Moreover, the space around the second target electrical appliance is narrow, and the second threading tube 14 can adapt to the narrow space well.

[0070] According to the position of the second target electrical appliance between the two bogies on the vehicle chassis 2 and the wiring requirements, a wire threading hole is opened on the wire trough body 7 and a corresponding wiring box 13 is configured.

[0071] The second threading tube 14 can be, but is not limited to, a hose. The second threading tube 14 is connected to the junction box 13 via a pipe joint. The hose can be deformed, so that the cables can be laid in advance, and the central wire duct 1 can be pre-assembled and then installed as a whole, which is time-saving and efficient.

[0072] In the embodiment of the present invention, the central wire duct 1 is formed by connecting at least two sub-wire ducts 15 in series, that is, the central wire duct 1 is a segmented splicing structure.

[0073] The central cable duct 1 further comprises a connector 16, which is used to connect the ends of two adjacent sub-cable ducts 15 together. Figure 4 and Figure 5 The sub-cable ducts 15 are set to a standard size, and the number of sub-cable ducts 15 can be selected according to the length requirement of the central cable duct 1.

[0074] The connecting member 16 includes a first connecting plate 17 , a second connecting plate 18 and a fastener 19 .

[0075] The first connecting plate 17 is annularly arranged on one side of the sub-wire groove 15 close to the vehicle chassis 2 and on the side part of the sub-wire groove 15, and the second connecting plate 18 is annularly arranged on one side of the sub-wire groove 15 far from the vehicle chassis 2 and on the side part of the sub-wire groove 15. The first connecting plate 17 and the second connecting plate 18 are arranged opposite to each other, and the fastener 19 fixedly connects the first connecting plate 17 and the second connecting plate 18 together to form a closed ring. Refer to Figure 6 .

[0076] The connecting piece 16 is annularly arranged at the position where two adjacent sub-wire grooves 15 are connected, and can seal the gap between two adjacent sub-wire grooves 15. The central wire groove 1 is of a closed type, which can avoid the electrical discontinuity of the structure, effectively reduce the common-mode coupling, and improve the shielding efficiency.

[0077] Specifically, the first connecting plate 17 and the second connecting plate 18 are provided with convex edges. After the first connecting plate 17 and the second connecting plate 18 are buckled together, the convex edges on the first connecting plate 17 and the convex edges on the second connecting plate 18 are overlapped. The connecting bolt and nut are selected as the fastener 19. After the connecting bolt penetrates through the convex edges on the first connecting plate 17 and the convex edges on the second connecting plate 18, it is locked with the nut. With such a setting, it is convenient to disassemble and assemble the connecting piece 16, and the assembly efficiency can be improved.

[0078] In this embodiment, the wiring structure of the vehicle frame further includes a sliding locking mechanism 20. The sliding locking mechanism 20 is provided between the central wire groove 1 and the vehicle frame, between the distribution box 3 and the vehicle frame, between the end wire groove 4 and the vehicle frame, and between the vehicle-end cross-connecting box 6 and the vehicle frame.

[0079] Through the sliding locking mechanism 20 between the central wire groove 1 and the vehicle frame, the position of the central wire groove 1 on the vehicle frame can be adjusted as needed. Through the sliding locking mechanism 20 between the distribution box 3 and the vehicle frame, the position of the distribution box 3 on the vehicle frame can be adjusted as needed. Through the sliding locking mechanism 20 between the end wire groove 4 and the vehicle frame, the position of the end wire groove 4 on the vehicle frame can be adjusted as needed. Through the sliding locking mechanism 20 between the vehicle-end cross-connecting box 6 and the vehicle frame, the position of the vehicle-end cross-connecting box 6 on the vehicle frame can be adjusted as needed. It can reduce the requirement for processing accuracy and improve the assembly accuracy at the same time.

[0080] Taking the sliding locking mechanism 20 between the central wire groove 1 and the vehicle chassis 2 as an example, the structural principle of the sliding locking mechanism 20 is described. As Figure 10 shown, the sliding locking mechanism 20 includes a sliding groove 22, a sliding bolt 23 and a locking nut 24. The sliding groove 22 is arranged on the vehicle chassis 2, and the sliding groove 22 extends along the longitudinal direction of the vehicle chassis 2. The nut of the sliding bolt 23 is embedded in the sliding groove 22. A connecting hole is arranged on the lifting earring 9. The threaded end of the sliding bolt 23 extends to the outside of the sliding groove 22 and passes through the connecting hole on the lifting earring 9, so that the locking nut 24 is locked and connected with the sliding bolt 23.
