Variable Damping Hinge for Electronic Devices

The damping mechanism is segmented into multiple independent damping members (first damping member and second damping member) instead of using a single conventional drag rotation shaft. Each damping member can independently provide resistance, allowing the system to achieve variable resistance through their cooperative operation while keeping each individual component relatively simple in structure.

The patent transforms the static resistance characteristic of conventional drag rotation shafts into a dynamic resistance system. The first and second damping members are configured to cooperate in different ways depending on the unfolding angle, with their contact states changing dynamically. This allows the resistance to adapt automatically to different operational states (folded, partially unfolded, fully unfolded) without requiring complex active control mechanisms.

The damping members are designed to automatically adjust their resistance output based on the unfolding angle without requiring external control systems. The mechanical configuration of the first and second damping members causes them to engage or disengage naturally as the electronic device transitions between folded and unfolded states, providing appropriate hand feel and resistance for each state through self-service operation.

The patent changes the resistance parameter dynamically based on the unfolding angle. By configuring the first and second damping members with different contact characteristics and positions, the system achieves variable resistance where the contact force between damping members changes as the angle changes, providing optimized hand feel for different operational scenarios without complex control mechanisms.

The support force mechanism is divided into multiple damping members that can be independently configured. The first damping member and second damping member can be designed with different damping characteristics, allowing the system to provide multiple discrete support force levels through their selective engagement, giving users different resistance options without requiring a single complex adjustable mechanism.

The system provides dynamically changing support forces based on the unfolding angle. As the electronic device transitions from folded to unfolded states, the first and second damping members naturally transition between different contact states, automatically providing appropriate support force for each angle range. This dynamic adaptation eliminates the need for manual adjustment mechanisms while maintaining multiple support force options.
