Description

Technical Field

[0001] This utility model belongs to the field of rail transit vehicle technology, and more specifically, it relates to a rail transit vehicle passenger compartment wiring harness fixing structure. Background Technology

[0002] Compared to high-speed trains, subways, and buses, APM (Automated People Mover) passenger compartments are smaller, have more equipment, and limited space. Cable trays are also unsuitable due to space constraints, so metal brackets are typically used for cable harness fixing. Currently, most APM passenger compartment wiring uses metal brackets for fixing. To compensate for the insufficient space for cable harness routing, the brackets are usually designed with different heights to meet the wiring harness laying requirements. This metal fixing method has the following drawbacks: 1) Poor versatility, often requiring customized design based on the wiring path. 2) Relatively heavy and costly, requiring holes to be drilled in the bracket for securing with cable ties. Therefore, a flexible and simple cable harness fixing bracket is needed that can reduce weight and cost while reliably fixing the cable harness.

[0003] Existing technology includes a device entitled "Wire Harness Fixing Device and Vehicle for Vehicles" with publication number CN117341604A. This technology relates to a wire harness fixing device and vehicle for vehicles. The wire harness fixing device includes: a fixing seat connected to the vehicle frame, the fixing seat including a threading part and a connecting part, at least a portion of the threading part and at least a portion of the connecting part being respectively located on opposite sides of the vehicle frame, the threading part for passing through a wire harness loop, and the connecting part connected to the threading part; and a connecting rod detachably connected to the connecting part, which, after being connected to the connecting part, can limit the relative position of the fixing seat and the vehicle frame. This application has a simple and lightweight structure, reducing the overall vehicle weight and production and installation costs. At least one mounting hole can be used to fix main lines of different weights and wire diameters. Furthermore, the fixing seat and connecting rod of the wire harness fixing device are detachably connected, allowing installation on vehicle frames of different structures, demonstrating good adaptability to vehicle frame size and structure. However, this technology does not address the technical problems and solutions of this application. Utility Model Content
