Sliding Door Support Mechanism for Inclination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door structures face the challenge of preventing the door from inclining forward when fully open, as the support point shifts, leading to instability and potential misalignment.
Innovation Solution
The sliding door structure incorporates a vehicle body rail support member and a door rail support member, where the support points are positioned to ensure the door is supported more towards the closing direction in the fully open state, with a reaction force generating section and an inclination suppressing wall to prevent forward inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the guide rail of the rear slide support section is provided on the door side, then design characteristics improve and the channel in the vehicle body can be eliminated, but the support point of the sliding door in the fully open state inclines to the vehicle front side, causing the door to incline
Solution Approach 1:
The inclination suppressing wall is positioned to preemptively counteract the forward inclination of the door before it occurs. When the door approaches the fully open state, the door side end section of the vehicle body rail support member contacts the inclination suppressing wall, generating a reaction force that prevents the door from inclining forward, thus maintaining door stability while allowing the guide rail to be positioned on the door side for improved design characteristics
2Reliability
If the support point is positioned more towards the door opening direction side, then the door can be supported in the fully open state, but the door tends to incline forward due to the support point shifting
Solution Approach 1:
The vehicle body rail support member is designed with differentiated functional sections: the door side end section that contacts the inclination suppressing wall to prevent forward inclination, and the guide rail engagement section that provides stable support. This local differentiation allows the support point to be positioned optimally for both support reliability and door alignment stability

AI summary
A sliding door structure in which a position where a door side end-section of a vehicle body rail support member is coupled to a door main body being further to a door closing direction side than a center-of-gravity position of a door, and a position of a door side end-section of a door rail support member in a fully open state being further to a door closing direction side than the center-of-gravity position of the door and further to a door opening direction side than a position where the door side end-section of the vehicle body rail support member is coupled to the door main body, and that further includes: an inclination suppressing wall provided at a vehicle body and configured so as to be abutted, from a vehicle lower side, by a reaction force generating section at least in the fully open state.
