A 3D Design System for Wire Harness

Abstract

The invention discloses a 3D design system of a wire harness, which is characterized in that it includes a parts library, a 3D design module and a process file module; the parts library includes a parts information library, a parts 3D digital model library and a 2D digital model library; The 3D design module includes a wiring module, a definition module and a 3D process module; the process file module calls the 2D digital model library according to the 3D design drawing obtained by the 3D design module to generate a board drawing; and according to the supplier wiring harness board drawing It is required to modify the default process parameters of the system, including the marking of the wire number by spraying code / casing, the order of sub-packaging, and the amount of wire loss corresponding to different processes. The design system of the present invention outputs accurate and detailed 3D diagrams to improve the effectiveness and accuracy of the design. Combined with electrical diagrams, wiring harness paths and process requirements, the direction and process of each wire is added to the initial 3D diagram, and the display is more accurate. , the wire diameter can be obtained directly based on the 3D digital model, without the need for wire diameter calculation.

Description

technical field [0001] The invention relates to automobile electrical design technology, in particular to a 3D design system for wire harnesses. Background technique [0002] The current low-voltage wiring harness design workflow is as follows: According to the definition of the low-voltage interface of each electrical equipment, the connection relationship between each electrical equipment and the required connector model, terminal model and other accessory models can be sorted out, and the electrical schematic diagram can be drawn; through 3D Drawing software, reasonably arrange the low-voltage wiring harness in the digital model of the vehicle and draw the 3D digital model of the low-voltage wiring harness to obtain the routing direction and length of each section of the wiring harness; use the 2D drawing software to draw a 2D drawing of the low-voltage wiring harness and output it to the wiring harness supplier to reflect each wire The input and output terminals, process...

AI Technical Summary

Problems solved by technology

In the above workflow, there are the following problems: 1. The models of the required parts, especially the models of the auxiliary materials for the connector, usually need to find the connector supplier to obtain the product specification, and the 3D digital model needs to be downloaded from the official website or Obtained by other means, the efficiency is low; 2. The wiring harness design process will be revised repeatedly. Since there is no interaction between the 3D and 2D drawings, if the 3D drawing is modified after the 2D drawing is completed, the 2D drawing must be manually modified again; 3. The wiring harness supplier The designer's 2D drawing cannot be used directly, it needs to be converted into an internal layout drawing. If the designer's drawing fails to clearly mark every detail, the actual product will deviate from the design
