Vehicle Display Device with Hinge and Sliding Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional car roof display devices have large bases that occupy significant space and are not easily upgradable, as the screen and base are fixedly connected, making it inconvenient to change or upgrade the display.
Innovation Solution
A display device with a base and a connecting module that includes a hinge and a sliding connecting assembly, allowing the display module to be detachably connected and rotated between two positions, enabling easy mounting, upgrading, and portability, with positioning members for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the screen and base are fixedly connected by connecting structures, then the structural stability is improved, but the ease of upgrading or changing screens deteriorates
Solution Approach 1:
The display device is divided into separate modules: a base module, a connecting module with hinge mechanism, and a display module. This segmentation allows the display module to be detached and replaced independently while maintaining the stability of the base and connecting structures.
Solution Approach 2:
The connecting module employs a hinge mechanism that provides both stable connection and dynamic adjustability. The hinge allows the display module to rotate between fixed positions while maintaining secure attachment, enabling both structural stability and ease of replacement.
2Stability of the object's composition
If a large base is used to mount the display device, then the mounting stability is improved, but the space occupancy deteriorates
Solution Approach 1:
The connecting module utilizes rotational movement around a hinge axis to provide mounting stability without requiring a large base area. By transitioning from a two-dimensional base expansion to a three-dimensional rotational mechanism, the device achieves stable mounting with reduced footprint.
3Adaptability or versatility
If the display module is made detachable from the base, then the ease of upgrading or changing screens is improved, but the device complexity deteriorates
Solution Approach 1:
A connecting module serves as an intermediary between the base and display module. This intermediate component with hinge mechanism simplifies the detachment and attachment process while providing stable connection, reducing the overall complexity compared to direct fixed connections or complex quick-release mechanisms.
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 a compact, easily mountable, and upgradable display device that can be used as a portable screen, reducing space occupancy and enhancing user convenience by enabling easy detachment and reattachment of the display module.
Implementation Method 1
the hinge has a pivot of which the center is defined as a central axis, the connecting assembly is connected to an end away from the pivot of the hinge, and the connecting assembly rotates back and forth between a first position adjacent to the inside roof and a second position away from the inside roof around the central axis
Implementation Method 2
the connecting assembly moves back and forth along a direction parallel to the central axis, such that the connecting groove and the connecting assembly are detachably connected

AI summary
A display device for vehicles is provided. The display device includes: a base, a connecting assembly and a display module. The connecting assembly is disposed on the base by a hinge. The hinge has a pivot of which the center is defined as a central axis. A connecting groove is disposed on the back side of the display module, such that the display module can be connected to the base when the connecting assembly is slidingly inserted into the connecting groove. The connecting assembly can slide in the opposite direction to be removed from the connecting groove of the display module.
