The flexible display screen 200 is provided with a first connection portion 210 and a second connection portion 220 connected to the first connection portion 210 and bendable with respect to the first connection portion 210. The folding device 100 includes a first support plate 110 fixedly attached to the first connection portion 210 and a second support plate 120 fixedly attached to the second connection portion 220, the first support plate 110 is rotatably connected to the second support plate 120, when the flexible display screen 200 is bent, the first support plate 110 rotates around a first axis 101 relative to the second support plate 120, and the first axis 101 is located on a neutral layer at a boundary between the first connection portion 210 and the second connection portion 220.
It may be appreciated that the first support plate 110 and the second support plate 120 support the first connection portion 210 and the second connection portion 220, respectively, and the first support plate 110 and the second support plate 120 rotate around the first axis 101 to drive the first connection portion 210 to bend relative to the second connection portion 220, so that the electronic device 1000 presents two use states of bending or flattening. The electronic device 1000 may be a mobile phone, a tablet computer, a notebook computer, or the like.
The folding device 100 is provided with the first support plate 110 fixedly attached to the first connecting portion 210 and the second support plate 120 fixedly attached to the second connecting portion 220, the first support plate 110 and the second support plate 120 rotate around the first axis 101, the first axis 101 is located at a neutral layer between the first connecting portion 210 and the second connecting portion 220, so that the first connecting portion 210 can be bent relative to the second connecting portion 220, no active area exists between the first connecting portion 210 and the second connecting portion 220, the active area of the flexible display screen 200 is reduced in the bending process, the occupation ratio of the inactive area is increased, the flexible display screen 200 is effectively supported stably in the unfolding or bending process, and the service life is prolonged.
In this embodiment, the flexible display 200 has a display surface 230 and a back surface 240 opposite to the display surface 230. The first connection part 210 and the second connection part 220 are disposed at two parts of the flexible display screen 200. The first connection portion 210 is integrally provided with the second connection portion 220. The first connection portion 210 and the second connection portion 220 are respectively bent under the driving action of the first support plate 110 and the second support plate 120. The first connection portion 210 is bent with the second connection portion 220, so that the display surface 230 and the back surface 240 are bent. The first support plate 110 and the second support plate 120 effectively support the first connection portion 210 and the second connection portion 220, respectively. The first support plate 110 and the second connection plate are flat plates, so that the first connection portion 210 and the second connection portion 220 are flat. When the flexible display 200 is bent at the junction of the first connection portion 210 and the second connection portion 220, the fold line formed between the first connection portion 210 and the second connection portion 220 is the same.
It will be appreciated that, in order that there is no active area between the first connection portion 210 and the second connection portion 220, it is required that the interface between the first connection portion 210 and the second connection portion 220 is pressed and pulled during bending, that is, the rotation axis of the first connection portion 210 rotating relative to the second connection portion 220 is located between two sides of the interface, that is, the rotation axis of the first connection portion 210 rotating relative to the second connection portion 220 is located on the neutral layer of the interface.
The first shaft 101 forms a rotation axis through which the first connection portion 210 rotates with respect to the second connection portion 220. The first axis 101 is a virtual axis, so that the first axis 101 is located on the neutral layer. When the first connecting portion 210 rotates relative to the second connecting portion 220, the outer layer at the junction between the first connecting portion 210 and the second connecting portion 220 is under tensile stress, the inner layer at the junction is under compressive stress, and a transition layer which is neither under tensile force nor compressive force exists on the cross section at the junction. The transition layer is formed between the outer layer and the inner layer at the interface of the first connection portion 210 and the second connection portion 220, the stress of the transition layer is almost equal to zero, and the transition layer forms a neutral layer at the interface of the first connection portion 210 and the second connection portion 220. The neutral layer is a surface substantially equal to the display surface 230 and the back surface 240, respectively, on a cross section of a boundary between the actual first connection portion 210 and the second connection portion 220. The first axis 101 is disposed on a neutral layer at a junction between the first connection portion 210 and the second connection portion 220, so that the junction between the first connection portion 210 and the second connection portion 220 is pressed and pulled during bending, and no active area exists between the first connection portion 210 and the second connection portion 220. Since there is no active area between the first connection portion 210 and the second connection portion 220, there is no stress fatigue area between the first connection portion 210 and the second connection portion 220, so that there is no obvious crease between the first connection portion 210 and the second connection portion 220, and appearance performance of the electronic device 1000 is improved.
Optionally, in the bending process of the first connecting portion 210 and the second connecting portion 220, the display surface 230 is pulled corresponding to the junction between the first connecting portion 210 and the second connecting portion 220, and the back surface 240 is pressed corresponding to the junction between the first connecting portion 210 and the second connecting portion 220.
Optionally, in the bending process of the first connecting portion 210 and the second connecting portion 220, the display surface 230 is pressed at the junction between the first connecting portion 210 and the second connecting portion 220, and the back surface 240 is pulled at the junction between the first connecting portion 210 and the second connecting portion 220.
Optionally, the first support plate 110 and the second support plate 120 are attached to the back 240 of the flexible display screen 200.
Optionally, the first support plate 110 and the second support plate 120 are attached to the display surface 230 of the flexible display screen 200.
Optionally, the first support plate 110 is adhered to the first connection portion 210 by glue.
Optionally, the first support plate 110 is adhered to the first connection portion 210 by double-sided adhesive.
Optionally, the second supporting plate 120 is adhered to the second connecting portion 220 by glue.
Optionally, the second support plate 120 is adhered to the second connection portion 220 by double-sided adhesive.
Further, the flexible display screen 200 is further provided with a movable portion 250, and the flexible display screen 200 is provided with two first connecting portions 210 respectively connected to two opposite sides of the movable portion 250, and two second connecting portions 220 respectively connected to two sides of the first connecting portions 210 away from the movable portion 250.
In this embodiment, the movable portion 250 is integral with the first connection portion 210. The movable portion 250 is disposed in the middle of the flexible display screen 200. The two second connection parts 220 are disposed at both ends of the flexible display screen 200. The folding device 100 is provided with two bodies 130, the bodies 130 being provided with the first support plate 110 and the second support plate 120. The first support plate 110 and the second support plate 120 are used to fixedly attach the first connection portion 210 and the second connection portion 220, so that the main body 130 may drive the first connection portion 210 and the second connection portion 220 to turn over relative to the movable portion 250, so that the flexible display screen 200 may assume a bent or flattened state. The junction between the movable portion 250 and the first connection portion 210 is determined by the junction between the flat portion of the flexible display screen 200 and the curved portion of the curved surface when the flexible display screen 200 is in the bent state.
When the flexible display screen 200 is in a folded state, the two second connection portions 220 are closed, the two first connection portions 210 are disposed at an included angle, and the movable portion 250 is curved and bent. Alternatively, the movable portion 250 may be curved in an arc. The two second support plates 120 clamp the two second connection portions 220. The two first support plates 110 respectively support and stabilize the two first connection portions 210, and bend the two first connection portions 210 relative to the two second connection portions 220, wherein edges of the two first connection portions 210 connecting the two second connection portions 220 are close, and edges of the two movable portions 250 are open, so as to ensure that the movable portions 250 are not damaged by compression.
When the flexible display screen 200 is in the unfolded state, the two first support plates 110 are spliced and in the flush state, and the two spliced portions of the two first support plates 110 support the movable portion 250, so that after the flexible display screen 200 is in the unfolded state, the movable portion 250 can be effectively supported, and the flexible display screen 200 is in the unfolded state and can be normally used. When the flexible display screen 200 is in the unfolded state, the first connection portion 210, the second connection portion 220 and the movable portion 250 are flush, so that the flexible display screen 200 is integrally flattened, the flatness of the display surface 230 is ensured, and the display performance of the display surface 230 is improved.
Optionally, when the flexible display screen 200 is in the folded state, an end of the first connection portion 210 adjacent to the movable portion 250 is tangent to an end of the movable portion 250 adjacent to the first connection portion 210, so that a bending radius of the movable portion 250 is minimized.
In this embodiment, the junction between the movable portion 250 and the first connection portion 210 is determined by the junction between the portion of the flexible display screen 200 that generates free bending and the portion that does not generate free bending during the process of changing the flexible display screen 200 from the flattened state to the folded state. The portion of the flexible display screen 200 that generates free bending refers to a portion that can be bent substantially in an arc-shaped curved surface during the folding process, and the portion that does not generate free bending refers to a portion that is substantially planar during the folding process, or a portion that is continuously bent substantially in two or more planes. Alternatively, the movable portion 250 is a region that is not acted upon by an external force during the change of the flexible display screen 200 from the flattened state to the folded state, and the first connection portion 210 and the second connection portion 220 are regions that are acted upon by an external force during the change of the flexible display screen 200 from the flattened state to the folded state. The two bodies 130 are attached to the back 240 of the flexible display 200. In particular, in this embodiment, the flexible display 200 is positioned inside the fold of the foldable device 100 to form an inward fold.
In the present application, the movable portion 250 is a region where the flexible display 200 can freely move during bending. That is, during the bending process of the flexible display screen 200, the movable portion 250 is separated from the folding device 100, so that the movable portion 250 can freely move. The movable portions 250 are connected to the two first connection portions 210, and the two first connection portions 210 may be supported by the first support plate 110, and no movable area exists between the first connection portions 210 and the second connection portions 220, so that the duty ratio of the movable portions 250 on the flexible display screen 200 is minimized, a larger portion of the flexible display screen 200 is effectively supported and stabilized during bending, and the service life of the flexible display screen 200 is prolonged. The end of the first connecting portion 210 adjacent to the movable portion 250 is tangent to the end of the movable portion 250 adjacent to the first connecting portion 210, so that the first connecting portion 210 and the movable portion 250 can be smoothly transitionally bent, no crease is formed between the first connecting portion 210 and the movable portion 2509, and the appearance performance of the electronic device 1000 is ensured.
Further, the folding device 100 further includes a rotating shaft base 140 rotatably connected to the two first support plates 110, and the rotating shaft base 140 is opposite to the movable portion 250.
In this embodiment, the spindle base 140 has two side portions rotatably connected to the two first connection portions 210, respectively. The rotating shaft base 140 generally forms a rotating shaft structure of the two first connecting portions 210, so that the two first connecting portions 210 can be turned over by the rotating shaft base 140, and the two second connecting portions 220 can be driven to be closed or opened. The spindle base 140 has a rectangular rod shape. The length direction of the spindle base 140 is parallel to the axial direction of the first shaft 101. The spindle base 140 is provided with a spindle cavity 141. When the flexible display screen 200 is in the folded state, the movable portion 250 may be at least partially accommodated in the rotating shaft cavity 141, so that the flexible display screen 200 forms an inner folded screen, and the electronic device 1000 is thinner and smaller after being folded, and is convenient for storage.
When the flexible display screen 200 is in the flattened state, the two first support plates 110 are spliced with each other and jointly cover the rotating shaft base 140, so as to support the movable portion 250 by the two first support plates 110.
When the flexible display screen 200 is in the folded state, the portions of the two first support plates 110 near the hinge base 140 extend into the hinge cavity 141 and are separated from the movable portion 250, so that the movable portion 250 is curved. The junction between the movable portion 250 and the first connection portion 210 forms a junction between the flexible display screen 200 attached to the first support plate 110 and the separation between the flexible display screen and the first support plate 110.
It may be appreciated that, in the process of bending the flexible display screen 200 from the unfolded state to the folded state, the first axis 101 is located at the boundary center layer of the first connection portion 210 and the second connection portion 220, so that the first connection portion 210 may be always fixedly attached to the first support plate 110, so that the inactive area of the flexible display screen 200 is effectively reduced, and the service life of the flexible display screen 200 is prolonged.
Further, referring to fig. 2 and 3, the folding device 100 further includes a rotating member 150 rotatably connected to opposite sides of the rotating shaft base 140, and the two rotating members 150 are slidably and telescopically connected to the two second support plates 120, respectively.
In this embodiment, the rotating member 150 drives the second supporting plate 120 to rotate around the rotating shaft base 140, and the rotating angle of the rotating member 150 around the rotating shaft base 140 is approximately 90 degrees, so as to fold the flexible display screen 200, and enable the two second connecting portions 220 to be folded to a closed state. The extending and contracting direction of the rotating member 150 relative to the second support plate 120 is perpendicular to the length direction of the rotating shaft base 140 and parallel to the direction of the second support plate 120. The rotating member 150 may be telescopic relative to the second support plate 120, so that the second support plate 120 may rotate relative to the first support plate 110, and the flexible display screen 200 may be folded to form a drop-shaped display screen. When the flexible display screen 200 is in the unfolded state, the rotating member 150 extends out relative to the second supporting plate 120, so that the flexible display screen 200 is effectively unfolded along with the folding device 100, and the second connecting portion 220 is stretched and unfolded relative to the rotating shaft base 140; when the flexible display screen 200 is in a bending state, the rotating member 150 contracts relative to the second supporting plate 120, so that the flexible display screen 200 is folded along with the folding device 100, and the second connecting portion 220 is folded and closed relative to the rotating shaft base 140. When the flexible display screen 200 is in the unfolded state, the first support plate 110 and the second support plate 120 are spliced and in the flush state, so that the two first support plates 110 and the two second support plates 120 support the flexible display screen 200 together, and the flexible display screen 200 obtains a flat and stable support platform.

Optionally, the sliding block 132 is provided with a sliding groove, and the sliding guide 133 is provided with a sliding rail slidingly matched with the sliding groove.
The rotating member 150 is provided with a rotating plate 151 rotatably fitted to an end of the rotating shaft base 140. The rotation plate 151 may cover an end of the rotation shaft base 140. Specifically, the spindle base 140 is provided with a bearing block 142 fixed in the spindle cavity 141. The bearing block 142 is provided with a rotation axis parallel to the length direction of the rotation axis base 140. The rotating plate 151 is rotatably connected to the rotating shaft. The bearing block 142 is further provided with a first rotation groove 1421 rotatably coupled to the first support plate 110. The main body 130 is provided with a first rotating wheel 134 fixed to the edge of the first support plate 110 away from the second support plate 120. The first rotating wheel 134 is rotatably engaged with the first rotating groove 1421, so as to realize the rotational connection between the first support plate 110 and the rotating shaft base 140. The first rotating wheel 134 is provided with two first arc grooves 1341 at two ends of the rotating shaft base 140 in the length direction. The inner wall of the first rotating groove 1421 is provided with a first arc flange 1422 slidably engaged with the first arc groove 1341. The geometric center line of the two first circular arc grooves 1341 forms a rotation axis 143 that is rotatably connected to the rotation axis base 140 and the first support plate 110. The rotation shaft of the first support plate 110 rotatably connected to the rotation shaft base 140 is a virtual shaft. The rotation shaft rotatably connected to the first support plate 110 and the rotation shaft base 140 is a second axis, that is, the second support plate 120 rotates around the second axis relative to the rotation shaft base 140. The rotation shaft rotatably connected to the rotation member 150 and the rotation shaft base 140 is a third axis, that is, the rotation member 150 rotates around the third axis relative to the rotation shaft base 140.
