In one specific implementation, the multiple main support pieces 3 are sequentially connected in a rotating manner, and specifically, two connected main support pieces can be connected through a connecting pin and rotate by taking the connecting pin as an axis. The self-supporting pieces a are respectively located on one side of the corresponding main supporting piece 3 facing away from the flexible display panel 1 and/or one side facing the flexible display panel 1, and each self-supporting piece a comprises a free end and a restrained end; the constrained ends of the self-supporting pieces a are pivotally connected to the corresponding main supporting pieces 3, and the free ends of the self-supporting pieces a rotate around the constrained ends and the pivot axes of the main supporting pieces 3.
In one implementation, the flexible display panel 1 is laid on the multiple main supports 3, and can be rolled or unrolled together with the multiple main supports 3 in a clockwise or counterclockwise direction. When at least part of the main supporting pieces 3 are in the rolled state, the free ends of the self-supporting pieces a on the main supporting pieces 3 in the rolled state are all rotated to the position where the main supporting pieces 3 adjacent to the main supporting pieces 3 are not in contact, where the position can be set by a user according to actual requirements, and a limiting structure can be set. When at least a part of the main support pieces 3 are in the unfolded state, the free ends of the self-support pieces a on the main support pieces 3 in the unfolded state are all rotated to the position where the self-support pieces a are in contact with the main support pieces 3 adjacent to the main support pieces 3, where the position can be set by a user according to actual requirements, and a limit structure can be set, which is not specifically limited in this embodiment, so that the joint of the two adjacent main support pieces 3 in the unfolded state can be prevented from being bent in a direction toward and/or away from the flexible display panel 1.
In one specific implementation, as shown in fig. 1-2, the self-supporting pieces a may each include a rotating piece 16, the rotating piece 16 is disposed on a side of the corresponding main supporting piece 3 facing away from the flexible display panel 1 (not shown in fig. 2, see the reference numerals in fig. 4), and the rotating piece 16 includes a rotating end and a following end opposite to the rotating end; the rotating end of the rotating piece 16 is pivotally connected with the corresponding main support piece 3 to form a first sub-constraint end of the constraint end, the rotating end of the rotating piece 16 can be pivotally connected with the corresponding main support piece 3 through a screw 17, and the rotating end of the rotating piece 16 can rotate by taking the screw 17 as an axis. The following end of the rotor plate 16 is formed as a second sub-restraint end of the free end, and the following end of the rotor plate 16 can be rotated by the screw 17 to be in contact with or not in contact with the adjacent main support 3.
As shown in fig. 2, when at least a part of the main support pieces 3 are in the rolled state, the rotating sheet 16 is parallel to the corresponding main support piece 3, the included angle between the rotating sheet 16 and the corresponding main support piece 3 is 0 ° or approximately 0 °, and the following end of the rotating sheet 16 and the rotating end of the rotating sheet 16 are both in contact with the corresponding main support piece 3, so that the butt joint of the two adjacent rolled main support pieces 3 can be bent in a direction away from the flexible display panel 1. As shown in fig. 1, when at least a part of the main support pieces 3 are in the unfolded state, the follower ends of the rotation pieces 16 are shifted, the rotation pieces 16 are no longer parallel to the corresponding main support pieces 3, that is, the included angle between the rotation pieces 16 and the corresponding main support pieces 3 is no longer 0 ° or is no longer approximately 0 °, the follower ends of the rotation pieces 16 are in contact with the adjacent main support pieces 3, and the rotation ends of the rotation pieces 16 are in contact with the corresponding main support pieces 3, so that the adjacent two main support pieces 3 can be supported by the rotation pieces 16, and the butt joints of the adjacent two main support pieces 3 in the unfolded state can be prevented from being bent in the direction away from the flexible display panel 1.
In one embodiment, the rotating end of the rotating plate 16 is provided with a rotating protrusion 21 and a rotating groove B. The rotating protrusion 21 can be moved in the rotating groove B to drive the rotating end of the rotating plate 16 to rotate along the rotating end of the rotating plate 16 and the pivot axis of the main support 3, so that the following end of the rotating plate 16 rotates around the rotating end of the rotating plate 16 and the pivot axis of the main support 3 to a position in contact with or not in contact with the adjacent main support 3, for example, after the moving protrusion in the display device is inserted into the rotating groove B, the rotating protrusion 21 can be moved to drive the rotating end of the rotating plate 16 to rotate along the rotating end of the rotating plate 16 and the pivot axis of the main support 3. And a slope is provided on the following end of the rotating plate 16 facing to one side of the main support piece 3, so that the following end of the rotating plate 16 rotates to a position contacting with the adjacent main support piece 3.
In one specific implementation, as shown in fig. 3, the main support pieces 3 each include a support portion 32 and connecting portions 31 at both ends of the support portion 32; the connecting portion 31 serves to rotatably connect two adjacent main support pieces 3.

The connecting end of the convex nozzle 15 is connected with the corresponding connecting part 31 to form a second sub-constraint end of the constraint end, wherein the connecting end of the convex nozzle 15 is connected with the corresponding connecting part 31; the pressing end of the nipple 15 forms a second sub-free end of the free end, and the pressing end of the nipple 15 can be pivoted to a position in contact with or not in contact with the adjacent main support 3 with the pivot axis of the connecting end of the nipple 15 and the main support 3 as an axis.
As shown in fig. 3, when the main support 3 is unfolded, the connecting end of the convex mouth 15 rotates along with the connecting portion 31, and drives the pressing end of the convex mouth 15 to contact with the adjacent main support 3, so as to press the butt joint of the adjacent two main supports 3 in the unfolded state, so as to prevent bending in the direction toward the flexible display panel 1. As shown in fig. 4, when the main support piece 3 is rolled up, the connection end of the convex nozzle 15 rotates along with the connection portion 31, and drives the pressing end of the convex nozzle 15 to be not in contact with the adjacent main support piece 3, and the butt joint of the adjacent two main support pieces 3 in the unfolded state is no longer pressed by the convex nozzle 15, so that the main support pieces can be bent in a direction away from the flexible display panel 1, and rolling up is achieved.
In the supporting structure of the embodiment, by providing the corresponding self-supporting piece a on the main supporting piece 3 for supporting the flexible display panel 1, when at least part of the main supporting piece 3 is in the rolling state, the free end of the self-supporting piece a on the main supporting piece 3 in the rolling state can rotate to a position where the main supporting piece 3 adjacent to the main supporting piece 3 is not in contact with, so that the butt joint of the two adjacent main supporting pieces 3 in the rolling state can be bent in a direction away from the flexible display panel 1, thereby rolling up the flexible display panel 1; when at least part of the main support pieces 3 are in the unfolded state, the free end of the self-support piece a on each main support piece 3 in the unfolded state rotates to the position where the main support piece 3 adjacent to the main support piece 3 is in contact with, so as to prevent the butt joint of the two adjacent main support pieces 3 in the unfolded state from bending along the direction towards and/or away from the flexible display panel 1, thereby realizing self-support through the self-support piece a of the support structure after the flexible display panel 1 is unfolded, not only improving the stability of the support structure, preventing the flexible display panel 1 from being folded in an undesired direction, but also improving the use effect of the flexible display panel 1.
In a specific implementation process, the supporting structure may further include a head support 18, and fig. 5 is a schematic structural diagram of the head support in the supporting structure, where the head support 18 is used for performing initial winding. In other words, the support structure starts to roll from the head support 18 when rolling, so that the head support 18 is located at the innermost side of the support structure when the support structure is in a rolling state; the head support 18 is located at the end of the support structure when the support structure is in the deployed condition.
FIG. 6 is a schematic view of the main support in the support structure. The head support 18 may take a similar configuration to that of the main support 3, and the difference therebetween will be described below with an emphasis, and the same configuration will not be described again.
As shown in fig. 5, the connecting portion 31 of the head support 18 is provided with a connecting block 311 and a head connecting pin 314; the connection block 311 and the head connection pin 314 are respectively positioned on both sides of the end of the head support 18; the connecting block 311 is used for fixing when rolling up, and the head connecting pin 314 is used for rotationally connecting with the rear connecting pin 312 of the first main supporting piece 3; as shown in fig. 6, the connecting portion 31 of the main support piece 3 includes a front connecting pin 313 and a rear connecting pin 312, and the front connecting pin 313 and the rear connecting pin 312 are respectively located at both sides of the end portion of the corresponding main support piece 3; in the adjacent two main support pieces 3, the rear connecting pin 312 of the previous main support piece 3 is rotatably connected with the front connecting pin 313 of the next main support piece 3. Wherein the rear connecting pin 312 of the previous main support 3 and the front connecting pin 313 of the next main support 3 can be connected by the connecting pin 10.
As shown in fig. 4, all the main support pieces 3 may be wound in a spiral manner, that is, the main support pieces 3 are wound from inside to outside in the same winding direction. The main support 3 can be wound into a cylindrical structure which is uniformly stacked from inside to outside by adopting a manual winding or machine winding mode.
In one specific implementation, the main support pieces 3 are arranged such that the width of the main support pieces 3 increases in the direction from the inner circle to the outer circle when the main support pieces 3 are in the rolled state, wherein the width of the main support pieces corresponds to an extending direction that is the same as or opposite to the rolling direction of the main support pieces, for example, in the embodiment shown in fig. 4, the width L3 of the outermost main support piece 3 > the width L2 of the middle main support piece 3 > the width L1 of the innermost main support piece 3.
Further, the width of each n main support pieces 3 is the same, where n is a positive integer greater than or equal to 2. In other words, every n main support pieces 3 have uniform width variations. In the embodiment shown in fig. 4, n =6. It is understood that n can be selectively set according to actual needs. In this way, the number of the main support pieces 3 per turn may be the same, for example, the number of the main support pieces 3 per turn may be m, which is a positive integer of 3 or more.
In one implementation, since the width of each n main supports 3 is known, the circumference of each circle can be calculated after rolling, and therefore, the slippage of the flexible display panel can be determined by the number of the rolled or unfolded main supports 3 during rolling or unfolding.
