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. The display screen 2 is disposed on the rotating shaft assembly 20, the first housing 10 and the second housing 30.

The first housing 10 includes a first supporting surface 101, the second housing 30 includes a second supporting surface 301, the first region 21 of the display screen 2 is fixedly connected to the first supporting surface 101, and the second region 22 of the display screen 2 is fixedly connected to the second supporting surface 301. It will be appreciated that the first housing 10 and the second housing 30 are made of a hard material, so that the first area 21 and the second area 22 of the display screen 2 have a better flatness due to the connection with the first supporting surface 101 and the second supporting surface 301, respectively. The part of the display screen 2 located between the first area 21 and the second area 22 is opposite to the rotating shaft assembly 20, and the part is not fixed with the rotating shaft assembly 20, so that the part can be freely bent.

In one embodiment, the first housing 10 includes an upper housing, a lower housing, and a frame connected between the upper housing and the lower housing. The upper surface of the upper housing is a first support surface 101. The second housing 30 has the same structure as the first housing 10 and is symmetrically disposed along a center line in a length direction of the foldable electronic device 100.

The bottom plate 210 has a semi-circular arc shape. The first side plate 211 and the second side plate 212 are oppositely disposed at two ends of the bottom plate 210 along the width direction of the foldable electronic device 100. The first side plate 211 and the second side plate 212 have the same structure. In other words, the first side plate 211 and the second side plate 212 are symmetrically disposed about a center line of the width direction of the foldable electronic device 100. A semi-cylindrical second receiving space 215 is formed between the bottom plate 210, the first side plate 211 and the second side plate 212.

The axis of the first rotating shaft 202 and the axis of the second rotating shaft 203 are along the Y-axis direction. The second end of the first rotating shaft 202 is rotatably connected to the first casing 10, so that when the first casing 10 rotates around the first rotating shaft 202, the first casing 10 bends relative to the casing 201. The fourth end of the second rotating shaft 203 is rotatably connected to the second housing 30, so that the second housing 30 is bent with respect to the casing 201 when the second housing 30 rotates around the second rotating shaft 203. When the included angle between the first casing 10 and the second casing 30 is 180 °, the first casing 10 and the second casing 30 are in the unfolded state, and the first casing 10 and the second casing 30 are coplanar. When the included angle between the first casing 10 and the second casing 30 is 0 °, the first casing 10 and the second casing 30 are in a folded state, at this time, the first casing 10 is parallel to the second casing 30, and the first region 21 and the second region 22 of the display screen 2 are attached to each other. When the included angle between the first housing 10 and the second housing 30 is greater than 0 ° and less than 180 °, the first housing 10 and the second housing 30 are in a bent state.

The elastic member 40 is provided with a first engaging portion 401 and a second engaging portion 402. The first engaging portion 401 abuts against the outer peripheral surface of the first rotating shaft 202 and engages with the first engaging portion 220 when the first housing 10 is bent by a first predetermined angle relative to the casing 201. The second engaging portion 402 abuts against the outer peripheral surface of the second rotating shaft 203 and engages with the second engaging portion 230 when the second housing 30 is bent by a second predetermined angle relative to the casing 201. The first preset angle and the second preset angle may be the same or different.

In one embodiment, the sensor is a pressure sensor, the pressure sensor is disposed on the first housing 10, and when the pressure sensor detects that the pressure acting on the first housing 10 is greater than or equal to a predetermined pressure, the sensor generates a rotation signal and transmits the rotation signal to the controller. The rotation signal may be an electrical signal, a digital signal, or the like. In other words, in the present embodiment, the triggering instruction detected by the sensor is that the pressure applied to the first casing 10 by the user is greater than or equal to the preset pressure. The preset pressure may be set by a user or a manufacturer.

Of course, in other embodiments, the sensor may be a light sensor, a temperature sensor, or an acoustic sensor. The sensor generates a corresponding rotation signal when detecting a trigger command such as a change of light, a change of temperature, or voice input, and transmits the rotation signal to the controller, so that the controller drives the first rotating shaft 202 and the second rotating shaft 203 to rotate according to the rotation signal.
