WIPO Patent Application WO/2022/267323

A1

Provided in the present invention are a chassis wiring method and structure for an urban rail vehicle. The chassis wiring method for an urban rail vehicle comprises: 1) simulation designing of a modular wiring harness: designing the model number of a first branch wiring harness according to voltage grades of an under-vehicle installation device and an on-vehicle installation device of a chassis; also designing the length of the first branch wiring harness; deploying an electronic product at an end part of the chassis, designing the position of a second branch wiring harness at a corresponding position on the corresponding first branch wiring harness, and designing the length of the second branch wiring harness; 2) offline assembly: according to the design results in step 1), performing offline assembly and wire connection on the first branch wiring harness, the electronic product and the second branch wiring harness, and forming an integrated module A; and 3) online assembly: integrally mounting, below the chassis, the module A formed in step 2). By means of the chassis wiring method in the present invention, maintenance and manufacture are facilitated, and the method has good platform performance and electromagnetic compatibility.
