Sliding Door Guide Pin and Mobile Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles with hybrid or electric powertrains, the bulky battery placement at floor level complicates the integration of the lower guide rail for sliding doors, making it difficult to manage the movement and positioning of sliding doors, especially with pronounced rear wheel arches and interior armrests.
Innovation Solution
The arrangement includes a locking mechanism that controls the movement of a sliding door's mobile support along a guide rail, allowing the door to transition between closed, intermediate open, and fully open positions, using a guide pin and latch system that enables the door to pivot and move efficiently around the battery placement, and an adjustable guide rail that can accommodate the curvature of the wheel arch.

1Reliability
If a lower guide rail is integrated into the floor of a vehicle with a hybrid or electric powertrain, then the sliding door can be properly guided and positioned, but the bulky battery placement at floor level interferes with the integration of the lower guide rail
Solution Approach 1:
The patent removes the lower guide rail from the floor area where the battery is located. Instead, the guide rail is positioned along the lower edge of the door opening, extracting the guidance function from the conflicted floor space while maintaining proper sliding door operation.
Solution Approach 2:
The guide rail is repositioned from a horizontal floor-mounted configuration to a vertical configuration along the door opening edge. This dimensional change allows the battery to occupy the floor space while the guide rail operates in the vertical dimension, eliminating spatial conflict.
2Volume of stationary object
If the guide rail is positioned to accommodate the battery placement, then the battery can be integrated at floor level, but the sliding door movement and positioning becomes difficult to manage
Solution Approach 1:
The patent introduces a mobile support with a receiving means (slot with stops) that acts as an intermediary between the guide rail and the sliding door. This intermediary component provides precise positioning control through the slot geometry, ensuring the door moves correctly even with the modified guide rail configuration.
Solution Approach 2:
The door assembly is segmented into a sliding door and a mobile support that moves along the guide rail. The mobile support contains the receiving means for the drive means, separating the guidance function (guide rail) from the door structure, which allows independent optimization of both components.
3Manufacturing precision
If a mobile support with receiving means and locking mechanism is used, then the sliding door can be precisely positioned at closed and intermediate open positions, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the interaction between the drive means and the receiving means. As the drive means moves along the slot, it automatically engages with the stop at the first position (closed) and the second position (intermediate open), eliminating the need for separate actuators or complex control systems.
Solution Approach 2:
The receiving means features a slot with stops that provides dynamic positioning - the drive means can move freely within the slot during transition, then automatically locks at predetermined positions. This dynamic mechanism achieves precise positioning without requiring active control at each position.
