Vehicle Handle Hinge Integration for Clanking Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle handle devices experience clanking and increased friction due to dimensional errors between the operation handle and lock knob, leading to unintentional operations and reduced assembly workability.
Innovation Solution
A vehicle handle device with a hinge-forming wall and engagement claw that restricts movement of the operation handle without requiring additional components, allowing for improved assembly workability and prevention of clanking and drag turning by integrating the hinge receiving parts and eliminating the need for a separate shaft member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lock knob is used to restrict movement of the operation handle, then the operation handle is constrained, but clanking occurs due to dimensional errors and friction increases
Solution Approach 1:
The invention extracts the movement restriction function from the lock knob and transfers it to the hinge receiving part structure. The hinge receiving part includes a shaft-form portion that fits into a hole-form portion, creating a built-in constraint mechanism that prevents clanking and friction issues between the operation handle and lock knob
Solution Approach 2:
The invention merges the hinge receiving part with the operation handle by forming the hinge receiving part integrally with the operation handle. This integration eliminates separate components and reduces dimensional error accumulation, thereby preventing clanking while maintaining movement restriction
2Object-affected harmful factors
If additional components are added to restrict operation handle movement, then clanking is prevented, but assembly workability decreases
Solution Approach 1:
The invention combines the hinge receiving part with the operation handle as an integral structure, eliminating the need for additional separate components. This integration maintains clanking prevention functionality while significantly improving assembly workability by reducing the number of parts to be assembled
Solution Approach 2:
The hinge receiving part structure provides self-contained movement restriction functionality within the operation handle itself. The shaft-form and hole-form portions create an automatic constraint mechanism that prevents clanking without requiring external additional components or complex assembly procedures

AI summary
The purpose of the present invention is to provide a vehicle handle device which has excellent assembly workability, and which is capable of effectively preventing the operation handle from clanking and the lock knob from drag turning. An operation handle (3) is slid in the rotation shaft direction from the position where the hinge-forming wall (1) is laid across a hinge plate (6) in which a hinge receiving part (2) on one side is formed, and the opposite side, and a shaft-form hinge receiving part (2) is formed integrally with one of the handle base (5) and the operation handle (3), is inserted into the hole-form hinge receiving part (2) of the other of the handle base (5) and the operation handle (3) and is mounted on the handle base (5); during the mounting operation, an engagement claw (7) protruding from the hinge-forming wall (1) engages elastically with the hinge plate (6) to limit movement in the separation direction.
