Vehicle Inside Handle Cable Connection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inside handle devices for vehicles are cumbersome to operate due to the difficulty in engaging the inner cable end with the engagement hole of the inner door handle.
Innovation Solution
The inside handle device features a handle base that swings to support a handle body with an operation portion and a cable connection recessed portion, along with a cable holding case that fixes the outer cable and holds the inner cable, allowing for easy connection and locking of the handle connecting portion to the handle body, and can be released by converting the load direction, eliminating the need for guiding and fitting the inner cable into an engagement hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner cable end is engaged with the engagement hole of the inner door handle by fitting, then the door latch device can be remotely controlled, but the connecting operation becomes troublesome and time-consuming
Solution Approach 1:
The patent divides the cable connection system into modular components: the cable holding case that pre-assembles the inner cable with its engagement portion, and the handle base with the engagement hole. This segmentation allows the complex fitting operation to be replaced by a simpler connection between the cable holding case and handle base, while maintaining the remote control function through the preserved cable-latch mechanism connection.
Solution Approach 2:
The cable holding case serves as an intermediary component that simplifies the connection process. Instead of directly fitting the inner cable end into the engagement hole, the cable holding case acts as a mediator that holds the cable and provides a standardized connection interface to the handle base, thereby eliminating the troublesome manual fitting operation while ensuring reliable cable engagement.
2Reliability
If the inner cable is permanently attached to the handle body, then the door latch device can be operated, but accidental door opening due to position changes from collision cannot be prevented
Solution Approach 1:
The patent implements a dynamic connection system where the cable holding case can be connected to or detached from the handle base as needed. This dynamic capability allows the system to maintain permanent attachment during normal operation for reliable latch release, while enabling temporary detachment after collision to prevent accidental door opening, thus adapting to different operational states.
Solution Approach 2:
The patent applies the discarding and recovering principle by allowing the cable holding case to be detached (discarded from the connected state) from the handle base when collision occurs, preventing harmful accidental door opening. The connection can then be recovered (re-connected) when normal operation is restored, maintaining the reliability of latch release operation while preventing harmful effects during abnormal conditions.

AI summary
This inside handle device for a vehicle is connected to a door latch device which is affixed to a door through a cable device having an inner cable inserted in an outer cable, and the inside handle device remotely operates the door latch device. The inside handle device is provided with: a handle base which supports in a rockable manner a handle body having at one end thereof an operating section which can be operated from a front surface, and having at the other end thereof a cable connection recess which is open in a rear surface direction; and a cable holding case which is provided with a cable affixation section having one end of the outer cable affixed thereto, can be connected to the handle base while holding a handle connection section formed at one end of the inner cable, and, in the connected state, engages the handle connection section with tne cable connection recess in the handle body. The cable holding case can be disengaged from the handle base by a connection cancelling force acting in a rear surface direction obtained by changing the direction of a load acting on the cable affixation section in the direction in which the outer cable is pulled.
