Steering Column Damping Mechanism for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steering columns experience noise due to inter-component collision when the driver switches the lever from the locking to unlocking state or adjusts the steering wheel angle, deteriorating the shifting feel and manipulation experience.
Innovation Solution
A steering column design featuring a plate bracket with a tilt slit, a fixing member, a rotating member with a guide slit and coupling hole, a guide pin, and a first damper that supports or removes from the guide pin during rotation, reducing noise through damping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lever is shifted from locking to unlocking state in the same direction as the spring elastic force, then the shifting feel is improved, but inter-component collision and noise occur
Solution Approach 1:
A damper is introduced between the lever and the rotating member to cushion the impact during lever shifting. The damper absorbs the kinetic energy and reduces the collision force between components, thereby reducing noise while maintaining the shifting feel.
Solution Approach 2:
The damper acts as an intermediary element between the lever and the rotating member. It mediates the interaction during lever shifting, preventing direct collision between the lever and other components while still allowing the necessary motion to occur.
2Stability of the object's composition
If the steering column tilting is stopped, then the structure is stabilized, but noise occurs due to inter-component collision
Solution Approach 1:
The damper is positioned to cushion collisions that occur when the steering column tilting is stopped. It absorbs the impact energy from component interactions during tilting operations, reducing noise while maintaining tilting stability.
Solution Approach 2:
The damper serves as an intermediary that prevents direct collision between components during tilting operations. It allows the tilting mechanism to stabilize while absorbing the impact forces that would otherwise cause noise.

AI summary
According to the present embodiments, the lever handling and tilt handling of a driver can be improved by reducing noise caused by collisions between components, which can be generated if the driver manipulates a lever from a locking state into an unlocking state or if the driver adjusts the angle of a steering wheel.
