Dual Door Window Drive Layout for Reduced Aperture Height Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric window drives in automobiles occupy a large space in the height direction of the window opening, affecting the assembly of other components.
Innovation Solution
A window structure with a driving assembly that includes a carrier, first and second door windows, and transmission members, where the transmission members are movably connected to the carrier and driven by a compact driving member to open or close the window opening in opposite directions, utilizing a sliding groove and reversing gears to minimize space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional electric window driving device is used, then the window can be opened or closed automatically, but the driving assembly occupies a large space in the height direction of the window opening
Solution Approach 1:
The patent repositions the power input portion of the driving member from the height direction to the width direction of the window opening. The driving member is arranged substantially perpendicular to the moving direction of the door window, with its power input portion positioned at the end farthest from the moving direction. This dimensional reorientation allows the transmission members to be arranged along the width direction rather than the height direction, significantly reducing the space occupied in the height direction while maintaining the automatic operation function.
2Length of stationary object
If the driving assembly is made compact to reduce space occupation, then the height direction space is reduced, but the assembly complexity increases
Solution Approach 1:
The patent divides the transmission function into separate transmission members, with each transmission member connected to the door window and the driving member. By segmenting the transmission path and arranging transmission members along the width direction, the design achieves compactness in the height direction while using straightforward mechanical transmission components that do not significantly increase assembly complexity.
Solution Approach 2:
The driving member is designed to simultaneously drive multiple transmission members through its multiple output portions. This multi-functional design allows a single driving member to control the movement of multiple components, reducing the overall number of separate driving units needed and thereby simplifying the overall assembly while achieving compact dimensions.

AI summary
In one aspect, a window structure includes a first transmission member driven by a first output portion to drive a first door window to move, and a second transmission member driven by a second output portion to drive a second door window to move. The first transmission member and the second transmission member are arranged along the extending direction M of the opening and closing side. The power input portion of the drive member is arranged at intervals with the first transmission member and the second transmission member along the height direction M of the window aperture. The first output portion and the second output portion are arranged along the extending direction M of the opening and closing side.
