Vehicle See-Through Display Positioning With Adaptive Tilt Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices lack effective means to adjust display height and orientation based on the position of the driver or passenger, leading to suboptimal viewing and information presentation.
Innovation Solution
A display device with a drive module using a ball screw member and link member, along with a four-bar linkage structure, adjusts the display's position and orientation based on the occupant's facial features, incorporating a see-through module for additional information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the display size is increased to provide more convenience information, then the information display capability is improved, but the viewing angle and alignment with the driver's position deteriorate
Solution Approach 1:
The display device is made dynamically adjustable in position and orientation through a drive module. The display can move vertically and tilt at various angles, allowing it to adapt to different driver positions and viewing requirements while maintaining optimal visibility of the increased display area.
2Ease of operation
If the display position is made adjustable to improve viewing alignment, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The complex mechanical adjustment system is replaced with a drive module that uses motorized actuation. The drive module converts electrical signals into precise mechanical movements, simplifying the control interface while achieving the required positional and angular adjustments through automated actuation rather than manual mechanical manipulation.
3Loss of information
If a see-through module is added to provide additional information transmission, then the information delivery capability is improved, but the device complexity increases
Solution Approach 1:
The see-through module is merged with the main display structure, sharing common mounting mechanisms and control systems. The see-through panel is integrated into the display assembly such that it functions as part of the overall information presentation system, reducing the need for separate mounting hardware and control circuits.
4Area of stationary object
If the display is positioned at the lowest point to maximize see-through area, then the see-through capability is improved, but the viewing angle for upper display areas deteriorates
Solution Approach 1:
The display is positioned at the lowest point for maximum see-through area but can be dynamically tilted upward through the drive module. This allows the display to maintain its low position for see-through functionality while providing adjustable upward tilting angles to ensure optimal viewing of all display areas when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for optimal display alignment with the occupant, enhanced usability, and efficient information presentation through adjustable height and tilting, while maintaining a clear see-through area.
Implementation Method 1
a ball screw member connected to the link member and configured to move in a straight line and rotate the link member
Implementation Method 2
the rubber member may be in contact with the front lower part of the front display and configured to block light from leaking through a gap between the see-through panel and the front lower part of the front display
Implementation Method 3
a reflector located inside the housing, positioned opposite the front lower part of the front display, and configured to reflect light transmitted from a lower area of the front display
Implementation Method 4
The drive module may be linked to a camera mounted on the vehicle, and configured to adjust the position of the front display based on a position of a specific facial portion of an occupant in the driver seat or the passenger seat

AI summary
A display device including a see-through area in a vehicle, a vehicle thereof, and display system thereof are provided. The display device includes a front display having display areas and located in front of a driver seat and a passenger seat of the vehicle, a drive module to adjust a position of the front display, and a see-through module adjacent to a front lower part of the front display when the front display is located at a lowest point. The see-through module includes a see-through panel to provide information to a driver and a passenger by transmitting light from a lower area of the front display.
