The two pipeline cavities are respectively located on both sides of the floor structure in the width direction Y, and the pipeline cavity extends along the length direction X of the vehicle body. The upper surface of the floor structure and the upper surface of the pipeline cavity together form the upper surface of the floor assembly. On this basis, the high-voltage cable 400 of the new energy locomotive (for example, the high-voltage wiring area a shown in the figure) is arranged on the lower surface of the floor structure. The two pipeline cavities are respectively a first cavity 210 and a second cavity, and the low-voltage cable of the new energy locomotive (for example, the low-voltage wiring area b shown in the figure) is arranged in the first cavity 210, and the pipeline of the new energy locomotive (for example, the pipeline layout area c shown in the figure) is arranged in the second cavity. Through the above design, the present disclosure realizes that the high-voltage cable 400, the low-voltage cable and the pipeline are all arranged under the vehicle. Moreover, the present disclosure sets the low-voltage cables and pipelines in two cavities respectively, which is equivalent to realizing modular structural design, optimizing space planning, making the space planning of cables and pipelines more reasonable, simplifying the difficulty of arranging cables and pipelines, simplifying interfaces, and improving collaborative operations and production efficiency. At the same time, the present disclosure can achieve spatial separation between the high-voltage cable 400 and the low-voltage cable, and there is no interference from each other in the design to manufacturing stages, which improves efficiency and is conducive to improving the electromagnetic compatibility (EMC) and electrical safety of new energy locomotives.

[0050] In one embodiment of the present disclosure, the low-voltage cables can be arranged in the first cavity 210 in a pre-wiring manner.

For example, the low-voltage cables can be arranged in the wire trough 310, and then the wire trough 310 is installed in the first cavity 210.

[0053] like Figure 2As shown, based on the design of arranging low-voltage cables in the cable duct 310, in an embodiment of the present disclosure, there may be at least two cable ducts 310, and these cable ducts 310 are arranged in sequence along the length direction X.

Moreover, a second mounting seat 211 can be arranged on the cavity wall of the first cavity 210, for example, welding or other installation forms can be adopted. On this basis, the first mounting seat 312 and the second mounting seat 211 are detachably connected, thereby realizing the detachable connection between the cable duct 310 and the first cavity 210. Among them, each cable duct 310 can perform operations such as pre-assembly, pre-wiring, and pre-crimping under the vehicle, and then the entire low-voltage pre-wiring is lifted to the same height as the second mounting seat 211 welded in the first cavity 210 through a lifting tooling, and then tightened as a whole.

Through the above design, the present disclosure can use the support rib 3123 to provide support and connection functions between the first mounting plate 3121 and the second mounting plate 3122, strengthen the structural strength of the first mounting seat 312, and optimize the assembly effect of the wire trough 310 and the first cavity 210.

[0057] like Figure 3 As shown, based on the design that the second mounting plate 3122 is connected to the slot via a connecting member, in one embodiment of the present disclosure, the connecting member can be a bolt. On this basis, the second mounting plate 3122 can be provided with a first mounting hole 31221, and the first mounting hole 31221 can be a long hole, the long axis direction of the long hole is parallel to the length direction X. In addition, the second mounting seat 211 can be provided with a second mounting hole. Accordingly, the bolt can be inserted into the first mounting hole 31221 and the second mounting hole to screw the first mounting seat 312 and the second mounting seat 211 together. Through the above design, using the design that the first mounting hole 31221 is a long hole, the present disclosure can realize the relative displacement of the first mounting seat 312 and the second mounting seat 211 along the length direction X and bolt connection at different positions, so as to realize the position adjustment of the wire trough 310 in the first cavity 210, which is conducive to the flexible arrangement of the low-voltage cable in the first cavity 210.

[0058] like Figure 4 As shown, based on the design that the connecting member is a bolt, in one embodiment of the present disclosure, the second mounting seat 211 can be provided with a movable nut seat at its second mounting hole, and the bolt also passes through the movable nut seat, thereby making it easier to adjust the relative position of the first mounting seat 312 and the second mounting seat 211.
