When the foldable display device is changed from the flat state to the folded state, the bent portion 110 is changed from the flat state to the arc state. The bending portion 110 may be located in a central region of the display module 1, or may not be located in the central region of the display module 1, that is, areas of the two sliding portions 120 may be equal or may not be equal, which is not specifically limited in the embodiment of the present disclosure.

In the embodiment of the present disclosure, the display side 140 of the display module 1 is the display side of the bending portion 110 and the two sliding portions 120; the non-display side 150 of the display module 1 is the non-display side of the bending portion 110 and the two sliding portions 120.

In the embodiment of the present disclosure, the rotating shaft structure 2 is located on the non-display side of the bending portion 110 in the display module 1, and the rotating shaft structure 2 may only include one gear set 21 or may include a plurality of gear sets 21. When the rotating shaft structure 2 includes a plurality of gear sets 21, the arrangement of the gear sets 21 may be set according to actual conditions, which is not specifically limited in the embodiment of the present disclosure. In one example, the number of the gear sets 21 is increased, the plurality of gear sets 21 are arranged along the long side direction of the bending portion 110, so that the gear sets 21 are distributed over the non-display side of the bending portion 110, the plurality of gear sets 21 support the bending portion 110 together, and when an external force is applied to the rotation shaft structure 2, the plurality of gear sets 21 rotate simultaneously.

The size and type of the plurality of gears 211 may also be set according to actual conditions, and this is not specifically limited in the embodiments of the present disclosure.

In the embodiment of the present disclosure, the first casing 3 and the second casing 4 are respectively located on the non-display sides of the two sliding portions 120 and are distributed on two sides of the rotating shaft structure 2. The first groove 31 and the second groove 41 are used for wrapping two sides of the two sliding parts 120 far away from the bending part 110 so as to prevent the edge of the display module 1 from being exposed to air.

In addition, when the foldable display device is converted from the flat state to the bent state, the two sliding portions 120 of the display module 1 move accordingly. Specifically, when the foldable display device is folded inward, the display sides of the two sliding portions 120 approach each other, so that the two sliding portions 120 move toward the groove bottoms of the first groove 31 and the second groove 41, respectively, and the distances between the two sides of the two sliding portions 120 away from the bending portion 110 and the groove bottoms of the first groove 31 and the second groove 41 decrease.

When the foldable display device is folded outward, the non-display sides of the two sliding portions 120 approach each other, so that the two sliding portions 120 move in directions away from the bottoms of the first and

second grooves

31 and 41, respectively, and distances between two sides of the two sliding portions 120 away from the bending portion 110 and the bottoms of the first and

second grooves

31 and 41 increase. Based on this, in order to prevent the slot bottoms of the first and

second grooves

31 and 41 from blocking the edge of the display module 1 when the foldable display device is converted from the flat state to the bent state, a gap is provided between the module edge of the display module 1 (the left and right sides of the display module 1 in fig. 2) and the slot bottoms of the first and

second grooves

31 and 41.

The folding display device provided by the embodiment of the disclosure can be folded inwards and outwards. When the folding display device is folded inwards, the display sides of the two sliding parts 120 gradually approach to each other, and the plurality of gears 211 in the rotating shaft structure 2 are driven to rotate, so that the meshing positions of the two adjacent gears 211 are changed, and the folding display device is changed from a flat state to a curved state. When the bending degree of the foldable display device is different, the folded-in state of the foldable display device is also different. For example, the foldable display device may be U-shaped, i.e. the two sliding portions 120 are parallel, as shown in FIG. 3 a. The foldable display device can be folded inwards until the outer sidewall of the first groove 31 of the first casing 3 contacts the outer sidewall of the second groove 41 of the second casing 4, as shown in fig. 3b, and the foldable display device is baseball-shaped, i.e. the width of the upper end of the foldable display device in fig. 3b is slightly smaller than that of the lower end.

When the folding display device is folded outwards, the non-display sides of the two sliding portions 120 gradually approach to each other, and the plurality of gears 211 in the rotating shaft structure 2 are driven to rotate, so that the meshing positions of the two adjacent gears 211 are changed, and the folding display device is changed from a flat state to a curved state. When the degree of bending of the foldable display device is different, the folded state exhibited by the foldable display device is also different. For example, when the angle at which the foldable display device is bent is small, the foldable display device may take the state shown in fig. 4a, in which the two sliding portions 120 form an obtuse angle therebetween. The foldable display device can be further folded outwards until one side of the first shell 3, which is far away from the display module 1, is attached to one side of the second shell 4, which is far away from the display module 1, and at this time, the foldable display device is U-shaped, as shown in fig. 4 b.

When the foldable display device is converted from the flat state to the folded state, the appearance wrapping member 5 is also bent accordingly. In addition, when display module assembly 1 is in the flat state, the surface of pivot structure 2 is kept away from of outward appearance cladding piece 5, the surface of keeping away from display module assembly 1 of first casing 3, and the surface parallel and level of keeping away from display module assembly 1 of second casing 4, or outward appearance cladding piece 5 keeps away from pivot structure 2 the surface of keeping away from display module assembly 1 of comparing in first casing 3, and the surface of keeping away from display module assembly 1 of second casing 4 is closer to display module assembly 1 more, thereby can steadily place on the plane when making folding display device be in the flat state.
