Automotive Display Assembly Internal Casing Thermal and EMC Design

The patent removes the screw fixation system entirely and replaces it with a clipping mechanism integrated into the housing structure. The display module is retained by friction-fit clips that engage with corresponding features on the module, eliminating the need for multiple screws and reducing assembly time while maintaining secure fixation without introducing tension that causes mura effect.

The patent replaces the mechanical screw-threaded hole system with a friction-fit clipping mechanism. The clips are molded into the housing and engage with recesses or features on the display module, providing secure retention through friction and geometric interlocking rather than threaded mechanical fastening, thereby eliminating assembly time consumption and mura effect.

The patent eliminates the screw fixation system and replaces it with integrated clipping features molded directly into the housing. This reduction in part count (from multiple screws to integrated clips) significantly reduces assembly cost while maintaining secure fixation through the clipping mechanism.

The patent merges the retention function previously performed by separate screw fasteners into the housing structure itself through integrated clipping features. This consolidation eliminates the need for additional screws and reduces assembly steps, thereby reducing manufacturing cost while maintaining fixation security.

The patent employs a composite construction where a plastic housing provides the outer structure and thermal management, while an internal metallic support frame or stiffening ribs provide the necessary mechanical stiffness and planarity. This composite approach allows the housing to function as a heat sink while the internal metallic structure prevents deformation that would cause mura effect.

The patent segments the housing structure into functional components: an outer plastic housing for thermal dissipation and an internal metallic support structure for mechanical stiffness. This segmentation allows each material to perform its optimal function - the plastic for heat sinking and the metal for structural rigidity and planarity maintenance.

The patent combines plastic housing material with metallic components (such as an internal frame, shielding layers, or metallic clips) that provide electromagnetic shielding. The plastic provides cost-effective manufacturing and thermal dissipation, while the integrated metallic elements provide the necessary EMC performance through their conductive properties.

The patent introduces metallic shielding elements as intermediary components between the external environment and the sensitive electronic components housed within. These metallic features (frames, clips, or shielding layers) act as electromagnetic barriers while the plastic housing maintains cost-effectiveness and ease of manufacture.
