FOLDABLE ELECTRONIC DEVICE INCLUDING FLEXIBLE DISPLAY ELEMENT

Smart overview of the Invention

The foldable electronic device comprises two main bodies connected by a hinge unit, supporting a flexible display. The hinge features a bendable support member and several slit members, each with a fixed and a free end. These slit members are arranged longitudinally and spaced apart, allowing the free ends to control the curvature of the flexible display when folded, preventing damage from sharp bends.

Background

Mobile devices often feature foldable designs for enhanced portability. Traditional displays limit the size and flexibility of these devices. With advancements in flexible displays, there's potential to increase screen size across foldable devices. However, these displays risk damage when bent sharply, necessitating structures that limit their curvature during folding.

Innovative Features

The device includes mechanisms to prevent the flexible display from folding in the wrong direction and to adjust the unfolding angle. The hinge unit, supported by both device bodies, integrates slit members that maintain a safe curvature radius. Gap-widening prevention members ensure the slit members remain properly spaced, further protecting the display.

Structural Details

• The hinge unit is equipped with sliding components for smooth operation.
• Gap-widening prevention members include wing portions and connection parts to maintain slit member spacing.
• Slots and protrusions on slit members secure connection parts, preventing separation.
• A sliding groove and rail system supports the hinge's movement along the device bodies.
• An unfolding angle adjustment unit allows for precise control of the device's open position.

Functionality and Adjustments

The unfolding angle adjustment unit enables locking at multiple positions between fully open and closed states, enhancing user control. It consists of an angle adjustment post and slot with locking portions for stability. This design ensures the flexible display remains secure and functional throughout its range of motion.
