The foldable electronic device features a flexible display supported by a foldable apparatus. This apparatus comprises two housings and a foldable assembly, which includes several components such as a main shaft, fastening brackets, transmission members, and a stop block. The design allows the device to transition between an opened and closed state, providing both compactness and a large display area when needed.
With the rise of flexible displays in electronic devices, foldable designs have become popular due to their lightness and durability. However, a common issue is overbending when unfolding, which can damage the display by exceeding its designed angle. This application aims to address this problem by precisely controlling the angle between the device's housings to prevent overbending and extend the display's lifespan.
The foldable assembly plays a crucial role in maintaining the structural integrity of the device. It ensures that when unfolded, the flexible display remains flat and fully functional, enhancing user experience through improved viewing and operation. Conversely, when folded, the device becomes compact, making it easy for users to carry and store.
The flexible display consists of non-bendable and bendable portions attached to respective housings. The foldable assembly includes transmission members with stop end faces that interact with stop faces on a stop block. This interaction controls the angle between components, preventing overextension and protecting the flexible display from damage.
The design incorporates symmetrical transmission members around a median face for stability and precision. The stop block limits movement to prevent excessive bending angles. Additionally, certain implementations include clamping members to further stabilize swing arms within the assembly. These features collectively enhance the device's durability and performance while minimizing space requirements within the assembly.
