  • Patent number: 10386894
    Abstract: A rotatable coupling device applied to flexible display screen includes two folding sections, a hinge disposed between the two folding sections and at least one responsive structure, which is connected with the folding sections. When the folding sections are unfolded/folded around the hinge, the responsive structure is unfolded/folded along with the folding sections. The folding sections and the responsive structure are relatively displaceable so that during the unfolding/folding process, the transmission of the deformation amount on inner and outer faces caused by the bending of the hinge can be interrupted. Therefore, the deformation amount is prevented from being further transmitted from the responsive structure outward. When the flexible display screen is coupled with the responsive structure, the responsive structure is able to absorb the deformation amount so as to eliminate the pulling or compression effect on the flexible display screen due to the deformation amount.

    Abstract: A hinge assembly includes first and second linkage rods pivoted to a base seat, a cam connected to the first and second linkage rods, and a kickstand support pivoted to the cam. A latch is disposed in the cam. When the first and second linkage rods, the kickstand support, and the cam are received inside the base seat, the latch is in a first locking position, where the latch locks rotational movement of the kickstand support relative to the cam. When the second linkage rod moves outward of the base seat and brings the first linkage rod to rotate relative to the cam, the latch is pushed by the kickstand support to move into a second locking position, where the first linkage rod is limited from rotating relative to the cam.
