AI Technical Summary

Technical Problem

In the existing technology, steering wheel wiring harnesses with telescopic adjustment functions are prone to friction and compression with surrounding components, resulting in wear of the insulation layer, signal interruption, and difficulty in accurately matching the telescopic stroke with the reserved length of the wiring harness, which can easily lead to accumulation, tangling, or pulling damage.

Method used

A telescopic steering wheel wiring harness structure is adopted, which realizes automatic winding and unwinding of the wiring harness through components such as winding roller, rotating shaft, gear, toothed plate and return spring in the housing. Combined with threaded rod and belt drive, the stability and smoothness of the wiring harness during the extension and retraction of the steering wheel are ensured.

Benefits of technology

This solution resolves the issues of wiring harness tangling and wear during steering wheel extension and retraction, improves the stability and safety of wiring harness connections, and extends the service life of the wiring harness.

Abstract

This utility model provides a telescopic steering wheel wiring harness structure, relating to the technical field of automotive steering system components. It includes a housing, a fixing plate fixedly connected to the side of the housing, and fixing holes on the surface of the fixing plate. A take-up roller is rotatably connected to the inner side of the housing, and the surface of the take-up roller is wound with the wiring harness body. A rotating shaft is rotatably connected to the inner side of the housing, and a gear is fixedly mounted on the surface of the rotating shaft. A toothed plate is slidably connected to the inner side of the housing. This utility model connects the fixing plate on the side of the housing to the telescopic fixed end of the steering wheel. The take-up roller winds the wiring harness body, and the rotating shaft drives the gear to mesh with the toothed plate. The toothed plate is connected to the telescopic movable end of the steering wheel via a connecting wire, realizing the automatic retraction and extension of the wiring harness as the steering wheel extends and retracts. This solves the problems of tangling and wear caused by telescopic adjustment in traditional steering wheel wiring harnesses, ensuring the stability and reliability of the wiring harness connection and improving the safety of use during steering wheel adjustment.
