Folding mechanism, folding screen and mobile terminal

Abstract

The invention provides a folding mechanism, a folding screen and a mobile terminal. The folding mechanism comprises multiple folding sheets, several guide parts and several pairs of elastic telescopicassemblies, and a circle center shaft of each guide part is located in a corresponding area between the front faces of two corresponding folding sheets. According to the folding mechanism, by arranging the guide parts for guiding every two adjacent folding sheets to slide curvedly along an arc and forming sliding ways for the corresponding ends of the guide parts to be slidably inserted in the side faces of the folding sheets, the multiple folding sheets can be conveniently curved along the arc; by arranging the several pairs of elastic telescopic assemblies for elastically pushing every twoadjacent folding sheets to get away from each other, bending of the multiple folding sheets is facilitated; and as the bending axis of every two adjacent folding sheets is the circle center shaft of the corresponding guide part and the circle center shaft of each guide part is located in the corresponding area between the front faces of the two corresponding folding sheets, the bending axis of every two adjacent folding sheets is close to the corresponding position between the two front faces, and when the front faces of the folding sheets support the flexible screen, the stretching and retracting deformation of the flexible screen can be reduced to better protect the flexible screen.

Description

technical field [0001] The present application belongs to the field of folding mechanisms, and more specifically relates to a folding mechanism, a folding screen and a mobile terminal. Background technique [0002] The flexible screen is also called flexible screen, and as an important application technology of OLED (Organic Light-Emitting Diode, organic light-emitting semiconductor), it has obtained important development in recent years. Flexible screens have the characteristics of being bendable, and the application scenarios of flexible screens are becoming more and more extensive. Some mass-produced foldable mobile terminals based on flexible screens such as foldable mobile phones have appeared on the market. Currently, foldable mobile terminals are divided into two schemes: flexible screen in-folding and flexible screen out-folding. It generally uses a hinge to support the flexible screen so that the flexible screen can be bent. However, the flexible screen is support...
