Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
As shown in fig. 1, fig. 1 is a schematic external structural diagram of a foldable electronic device 100 according to an embodiment of the present application. The foldable electronic device 100 comprises a foldable housing assembly 1 and a display screen 2. The foldable electronic device 100 provided in the embodiment of the present application may be an inward-folding electronic device in which the display screen 2 is disposed on the foldable housing assembly 1, and the display surface of the display screen 2 is in contact with the inward-folding electronic device in the folded state, or an outward-folding electronic device in which the display surface of the display screen 2 is disposed on the foldable housing assembly 1 in the folded state. The following embodiments are described by taking the foldable electronic device 100 as an example without specific descriptions, and will not be described in detail later.
The foldable electronic device 100 provided in the embodiment of the present application may be a foldable display device, such as a mobile phone, a tablet, an electronic reader, a computer, an electronic display screen, and other various display devices. It is understood that the foldable electronic device 100 may also be a foldable non-display device. The present application exemplifies a foldable mobile phone. In this embodiment, the length direction of the foldable electronic device 100 is defined as the X-axis direction. The width direction of the foldable electronic device 100 is defined as the Y-axis direction. The thickness direction of the foldable electronic device 100 is defined as the Z-axis direction. Wherein, the direction indicated by the arrow is the positive direction.
Referring to fig. 2, the display screen 2 may be a hard screen or a flexible screen. Because the foldable electronic device 100 provided with the flexible screen is freely bent in order to realize the free bending of the flexible screen, the region of the flexible screen corresponding to the rotating shaft assembly 20 is not adhered to the rotating shaft assembly 20 or the shell, the region of the flexible screen corresponding to the rotating shaft assembly 20 is difficult to be completely flattened in the unfolded state, the region of the flexible screen corresponding to the rotating shaft assembly 20 is bent in the folded state, the flexible screen is difficult to keep the folded state when no external force is applied to make the flexible screen stable in the bent state, the foldable electronic device 100 is likely to be in a half-opened state, and the portability and the like of the foldable electronic device 100 are further affected. Therefore, the present application mainly solves the problem of how to stabilize the foldable electronic device 100 provided with a flexible screen in a folded, unfolded, or bent state, and ensure the flat display effect of the flexible screen and the portability of the foldable electronic device 100.
As shown in fig. 2, the foldable housing assembly 1 includes a rotary shaft assembly 20, a first housing 10, and a second housing 30.
