Head-Up Display Cover and Board Synchronization Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display (HUD) devices without protecting covers are susceptible to damage from sunshine and dust, and existing solutions with protecting covers complicate the driving mechanism and increase costs.
Innovation Solution
An HUD device with a sliding projecting board assembly and a driving mechanism comprising a link, lever, and driving wheel, where the driving wheel rotates to move the protecting cover and projecting board assembly between stored and displayed positions, also incorporating a light source protecting cover to simplify the structure and reduce costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protecting cover is added to protect the projecting board, then the projecting board is protected from sunshine and dust, but the driving mechanism becomes complicated and costs increase
Solution Approach 1:
The patent combines the protecting cover and light source protecting cover into a single integrated component that moves together with the projecting board assembly. The protecting cover is connected to the projecting board assembly through a connection structure, allowing them to move synchronously as one unit, thereby simplifying the driving mechanism while maintaining protection functionality.
Solution Approach 2:
The protecting cover serves multiple functions simultaneously: it protects the projecting board from external elements (sunshine and dust) and also protects the light source by integrating with the light source protecting cover. This multi-functional design eliminates the need for separate protection mechanisms, reducing overall system complexity.
2Reliability
If a light source protecting cover is added to protect the light source, then the light source is protected from damage, but additional driving mechanisms are required increasing complexity and cost
Solution Approach 1:
The protecting cover and light source protecting cover are merged into a single integrated structure. The light source protecting cover is connected to the protecting cover, allowing both components to be driven by the same motor assembly without requiring separate driving mechanisms.
Solution Approach 2:
The protecting cover and light source protecting cover are designed to move automatically with the projecting board assembly through connection structures. When the projecting board assembly moves between projection positions, the protecting covers follow along, eliminating the need for independent driving systems.
3Adaptability or versatility
If separate driving mechanisms are used for protecting cover and light source protecting cover, then each component can be controlled independently, but the structure becomes complicated and costs increase
Solution Approach 1:
The patent merges the driving functions by connecting the protecting cover and light source protecting cover to the projecting board assembly through connection structures. This allows a single motor assembly to drive all components simultaneously, maintaining coordinated movement without requiring independent control systems.
Solution Approach 2:
The connection structures create a synchronized movement system where the protecting cover, light source protecting cover, and projecting board assembly move together at the same rate and direction. This equipotential movement ensures all components remain in their proper positions relative to each other without complex control mechanisms.

AI summary
A head-up display device includes a housing, a guiding base, a projecting board assembly, a protecting cover and a driving mechanism. The projecting board assembly is movably arranged at the guiding base. The driving mechanism includes a link, a lever, and a drive wheel. A front end of the link is pivotally connected to the protecting cover, and a rear end of the link is engaged with the drive wheel. A lower end of the lever is pivotally connected to the projecting board assembly. The drive wheel is rotatable and can be selectively engaged with the lever. The rotation of the drive wheel can drive the link and the lever to move and thus drive the protecting cover and the projecting board assembly to move. Therefore, the driving mechanism can be more easily arranged, so as to simplify the structure and reduce cost.
