Vehicle Door Window Glass Support Structure Position Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door window glass support structures face challenges in achieving high position accuracy between the window glass and the sash part, particularly due to the separation of the guide rail from the sash part, leading to errors in assembly and accuracy issues in modern door designs with flush surfaces.
Innovation Solution
A vehicle door window glass support structure with a sash part that includes a guide section surrounded by walls in the vehicle interior and exterior directions, and an intersecting direction, utilizing a slider with elastic contact parts to ensure precise positioning of the window glass along the sash part, enhancing accuracy control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the guide rail is separated from the sash part and attached to the inner panel, then the structure allows easier assembly and manufacturing flexibility, but the position accuracy between the window glass and the sash part deteriorates due to assembly errors and misalignment
Solution Approach 1:
The guide section is integrated into the sash part itself, merging the positioning function with the sash structure. This eliminates the separate guide rail attachment to the inner panel, thereby removing the source of assembly errors and misalignment while maintaining manufacturing flexibility through the unified design.
2Device complexity
If the guide rail is attached to the inner panel, then the structure is simpler and easier to manufacture, but the position control reliability between the window glass and the sash part deteriorates
Solution Approach 1:
The guide section is formed as an integral part of the sash structure, combining the guiding function with the sash itself. This integration ensures that the guide section and sash part move together as a unified structure, eliminating relative position errors and enhancing position control reliability while maintaining structural simplicity.
3Ease of manufacture
If the guide rail is separated from the sash part, then manufacturing and assembly are easier, but the position accuracy control between the window glass and the sash part becomes more difficult
Solution Approach 1:
The guide section is integrated into the sash part, merging the positioning reference with the sash structure itself. This eliminates the need for separate alignment and positioning of a detached guide rail, thereby maintaining assembly ease while significantly improving position accuracy control between the window glass and the sash part.

AI summary
A vehicle door window glass support structure includes: a sash part protruding upward with respect to the door panel; and window glass that is elevated or lowered along the sash part, in which the sash part includes a glass position regulating means that determines the position of the window glass in both vehicle interior and exterior directions and an intersecting direction that intersects the vehicle interior and exterior directions at least at a position where the window glass is elevated most. This configuration makes it possible to improve the position accuracy of the window glass with respect to the sash part, enhancing the appearance quality and the support performance of the window glass.
