Movable Display Cover Assembly With Rotator to Prevent Bending

The rotator acts as an intermediary component between the cover assembly and the bar. It transfers the movement force from the cover to the bar while preventing direct contact that would cause bending. The rotator's cylindrical shape allows smooth rotational movement, enabling the cover to open and close without bending deformations.

The patent replaces direct sliding contact with rotational contact. Instead of the cover sliding against the bar (which creates high friction and noise), the cover rotates the rotator, which then moves along the bar. This substitution of mechanical interaction mode significantly reduces friction and noise while maintaining the bending prevention function.

The bar serves multiple functions: it provides structural support to prevent cover bending, acts as a guide for the rotator's movement, and serves as a mounting structure for the rotator. By making the bar multi-functional, the patent avoids adding separate components for each function, thereby maintaining simplicity while achieving strength and support.
