The structural features, functional features, and the like of the folding display device provided in the embodiments of the present application are described below with reference to the accompanying drawings.
In an embodiment, please refer to fig. 1 to 3, fig. 1 is a partial exploded view of a first folding display device provided in an embodiment of the present application, fig. 2 is a first view of a folding mechanism of the first folding display device provided in an embodiment of the present application, and fig. 3 is a second view of the folding mechanism of the first folding display device provided in an embodiment of the present application.
In this embodiment, the folding display device includes a folding mechanism 10 and a flexible display panel 20 disposed on the folding mechanism 10. The folding mechanism 10 has a supporting function for the flexible display panel 20, and supports free conversion of the flexible display panel 20 between a flattened state and a folded state. At least a part of the area of the flexible display panel 20 has a flexible and bendable property to enable bending or unfolding following the folding mechanism 10. The flexible display panel 20 may be an organic light emitting diode display panel.
Specifically, the folding mechanism 10 includes a connector 11, first and second supports 12 and 13, and first and second rotating shafts 14 and 15. The first supporting member 12 and the second supporting member 13 are respectively disposed at two opposite sides of the connecting member 11; the first rotating shaft 14 and the second rotating shaft 15 are respectively arranged on two opposite sides of the connecting piece 11, which are connected with the first supporting piece 12 and the second supporting piece 13. The first supporting member 12 is rotatably connected to one side of the connecting member 11 through the first rotating shaft 14, and the second supporting member 13 is rotatably connected to the other side of the connecting member 11 through the second rotating shaft 15, so as to realize the foldable characteristic of the folding mechanism 10.
Wherein, the distance between the first rotating shaft 14 and the second rotating shaft 15 is variable, and the distance between the first rotating shaft 14 and the second rotating shaft 15 can be a first interval or a second interval by adjusting the distance, and the first interval is larger than the second interval. It is understood that the first rotating shaft 14 and the second rotating shaft 15 are disposed parallel to each other, and the first interval and the second interval refer to the linear relative distance between the first rotating shaft 14 and the second rotating shaft 15.
The radius of rotation of the first support 12 when the distance between the first rotating shaft 14 and the second rotating shaft 15 is a first distance is smaller than the radius of rotation of the first support 12 when the distance between the first rotating shaft 14 and the second rotating shaft 15 is a second distance. Correspondingly, the radius of rotation of the second support member 13 when the distance between the first rotating shaft 14 and the second rotating shaft 15 is the first distance is smaller than the radius of rotation of the second support member 13 when the distance between the first rotating shaft 14 and the second rotating shaft 15 is the second distance. Through the above arrangement, the thickness of the folded display device can be changed, which is beneficial to adopting a larger folding thickness to protect the flexible display panel 20 when the display device is stored for a long time, and adopting a smaller folding thickness to achieve the purpose of portability when the display device is carried.
The thickness of the folded display device when the distance between the first rotating shaft 14 and the second rotating shaft 15 is a first distance is greater than the thickness of the folded display device when the distance between the first rotating shaft 14 and the second rotating shaft 15 is a second distance, so that the folded display device can be freely switched between different folded thicknesses.
Further, the foldable display device further includes a limiting member 16 movably connected to the first rotating shaft 14 and the second rotating shaft 15. Optionally, the folding display device includes two limiting members 16, and the two limiting members 16 are respectively disposed at opposite ends of the first rotating shaft 14 and opposite ends of the second rotating shaft 15. The limiting member 16 is configured to limit a distance between the first rotating shaft 14 and the second rotating shaft 15, and facilitate switching of the distance between the first rotating shaft 14 and the second rotating shaft 15 between the first pitch and the second pitch.
Specifically, the limiting member 16 includes a first positioning groove 161 and a second positioning groove 162; when one end of the first rotating shaft 14 and one end of the second rotating shaft 15 are both located in the first positioning groove 161, a distance between the first rotating shaft 14 and the second rotating shaft 15 is the first distance; when one end of the first rotating shaft 14 and one end of the second rotating shaft 15 are both located in the second positioning groove 162, the distance between the first rotating shaft 14 and the second rotating shaft 15 is the second distance, so that the distance between the first rotating shaft 14 and the second rotating shaft 15 is adjustable.
Further, at least a portion of the stop 16 is conical and has a conical cavity; the first positioning groove 161 and the second positioning groove 162 are both disposed in the conical cavity of the limiting member 16, and the distance between the second positioning groove 162 and the conical top of the conical cavity of the limiting member 16 is smaller than the distance between the first positioning groove 161 and the conical top of the conical cavity of the limiting member 16. It will be appreciated that for conical members, the radius of the circumference of the region closer to the cone apex of the cone is smaller; therefore, the distance between the first rotating shaft 14 and the second rotating shaft 15 is adjustable by providing the conical limiting member 16 in the present embodiment.
To improve the function and structure of the stopper 16, the stopper 16 further includes a fixing member 165 and a horizontal slideway 164. The fixing piece 165 is fixedly connected to the conical opening of the limiting frame 16; one end of the horizontal slideway 164 is fixedly connected with the fixing member 165, and the other end is fixedly connected with the cone top of the limiting member 16. The horizontal slideway 164 is used for realizing the conversion between the first rotating shaft 14 and the second rotating shaft 15 from the first positioning slot 161 to the second positioning slot 162.
The folding display device further includes a telescopic member 163 disposed between the first rotating shaft 14 and the second rotating shaft 15, and the telescopic member 163 limits the first rotating shaft 14 and the second rotating shaft 15 on the inner wall of the cavity of the limiting member 16. In the process of switching the first rotating shaft 14 and the second rotating shaft 15 from the first positioning groove 161 to the second positioning groove 162, the telescopic member 163 moves along the horizontal slideway 164, and the telescopic member 163 realizes the change of the distance between the first rotating shaft 14 and the second rotating shaft 15 by compressing the length of the telescopic member 163.
Optionally, the stopper 16 further includes a third positioning groove 166, and a distance between the third positioning groove 166 and a cone apex of the conical cavity of the stopper 16 is smaller than a distance between the second positioning groove 162 and a cone apex of the conical cavity of the stopper 16. When one end of the first rotating shaft 14 and one end of the second rotating shaft 15 move along the horizontal slideway 164 into the third positioning groove 166, the distance between the first rotating shaft 14 and the second rotating shaft 15 is further reduced, and the thickness of the folded display device in the folded state is reduced, so that the folded display device is more portable.
In summary, in this embodiment, by setting the first rotating shaft 14 and the second rotating shaft 15 with variable pitches, the rotating radii of the first supporting member 12 and the second supporting member 13 are adjustable, so that the thickness of the folded display device is adjustable, which is beneficial to adopting a larger thickness to protect the flexible display panel 20 when the display device is stored for a long time, and adopting a smaller thickness to achieve the purpose of portability when the display device is carried.
