Description

Hinge device for in-out folding {Hinge Device in both Infolding and Outfolding Way}

The present invention relates to a hinge device for in-out folding, and more specifically, when a user folds a foldable smart display device having a flexible display panel installed on the inside in an in-folding state on the opposite side, the flexible display panel is disposed on the outside. In the hinge device implemented in the folding method, a round support is installed inside the joint so that the joint maintains a semicircular shape in the folded state and a straight shape in the unfolded state, and the user of the folding smartphone can view the screen of the closed smartphone at a certain angle When it is opened only as much as possible, the first body and the second body of the smartphone are automatically opened at a predetermined angle by the elastic force of the elastic actuator installed inside the smartphone even if the motor is not installed inside the smartphone, and also the first body by a predetermined angle. It relates to a hinge device for in-out folding, characterized in that a semi-automatic module is installed to completely close the first body and the second body automatically when the second body and the second body are closed.

In general, a flexible display panel is a display panel that can be bent with a predetermined curvature. Since such a flexible display panel uses a plastic substrate rather than a generally used glass substrate, a low-temperature manufacturing process is mainly used instead of a conventional manufacturing process in order to prevent damage to the substrate.

Such a flexible display panel is manufactured as, for example, a touch screen capable of capacitive or pressure-sensitive touch input so as to receive a user's command in a touch method.

On the other hand, the conventional portable foldable display device has a flexible display panel capable of touch input as described above. In such a conventional foldable display device, a predetermined accommodating space in which a folded portion of the flexible display panel can be bent in a curved shape is formed at a portion where a pair of bodies supporting the flexible display panel are hingedly connected to each other.

According to the hinge device for in-out folding according to the present invention, a flexible display panel is installed on the inner surface in an in-folding state in which the first body part and the second body part are folded inward, and the first body part and the second body part are placed opposite the user. In the case of folding, the flexible display panel is implemented in an out-folding method in which the flexible display panel is placed on the outside, and the flexible display panel is implemented on the inner and outer surfaces, so that a flexible display that implements in-folding and out-folding at the same time is installed. There is a remarkable effect of providing a smart phone to the user.

In addition, in the in-folding state, the foldable smart display device with the flexible display panel installed inside is maintained in a semicircular shape in the folded state of the joints while the user folds or unfolds the foldable smart display device, and in the unfolded state, the foldable smart display device is straight. A round support consisting of a semicircular round portion and a straight support is installed inside the joint portion to hold the joint portion, which has a remarkable effect of preventing the shape of the joint portion from collapsing or being bent in an S shape.

The outer surface of the slider and the outer joint of the present invention is finished with rubber or the like, or the surface of the outer joint is invisible by insert injection.

In addition, due to the installation of the central joint, a slight empty space is formed between the inner joint portion to which the flexible panel is attached and the outer joint portion to which the screen plate is installed, so that the space through which the FPCB passes can be configured.

In addition, the left and right joint units directly connected to the central joint are rotatable by 180 degrees, and stoppers are formed so that the remaining joint units rotate only inward.

In addition, according to the hinge device for in-out folding having a round support according to another embodiment of the present invention, when the first body part and the second body part according to the present invention are opened, the auxiliary body is moved by the elastic force of the spring of the elastic actuator. Elastic force is applied to the push bar, and the upper and lower protrusions of the push bar located at the intersection of the guide holes of the upper and lower plates of the semi-automatic module are attached to the upper and lower plates of the semi-automatic drive unit. First and second body parts , And by applying elastic force to the slider, when the user opens the first body and the second body of the present invention, the first body and the second body are opened in a straight line by the elastic force of the elastic actuator even if the motor is not installed therein There is a remarkable effect of becoming

In addition, when the user closes the first body part and the second body part by a certain angle by applying a certain force to the open folding smartphone, the first body part and the second body part according to the present invention are semi-automatic by the elastic force of the elastic driving body. 2 There is a remarkable effect that the body is configured to be completely closed.

In addition, in the state in which the first body part and the second body part according to the present invention are folded, the flexible display panel (FD) is folded due to the thickness of the central joint formed in the central joint, and the folded part is not completely folded and forms a curved surface. Therefore, there is a remarkable effect of preventing damage to the folded portion of the flexible display panel in a so-called "in-folding" state.

In addition, since the main body of the elastic driving body according to the present invention is configured to rotate at the same time as the gear gear is formed at the part where the main body contacts each other with respect to the center joint, the pair of main bodies of the elastic driving body adjacent to each other There is a remarkable effect that the bodies rotate at the same angle, and the main body and each of the auxiliary bodies connected to each other rotate at the same angle at the same time.
