AI Technical Summary

Technical Problem

In the existing technology, the main wiring harness of the engine is prone to bending and deviation when threaded in the narrow space of the engine compartment, resulting in low assembly efficiency and the risk of wiring harness damage. Traditional flexible protective sleeves are difficult to meet the requirements of convenient installation and reliable use.

Method used

The system employs a first and second protective sleeve that are alternately distributed along the axis of the main wire harness. Through a lockable hinge structure consisting of a hinge boss, hinge strip hole, locking block, top block, and unlocking slider, combined with a synchronous linkage unlocking mechanism consisting of a reel and a linkage rope, the system achieves the switching between rigid and flexible connection states, ensuring that the wire harness can be smoothly laid out in narrow spaces and adapts to deformation during use.

Benefits of technology

It enables efficient installation in the engine compartment, avoids bending and misalignment of the wiring harness during the wiring process, improves assembly efficiency, and provides adaptive protection during use, extending the service life of the wiring harness.
