[0047] Embodiment one

[0048] The embodiment of the utility model provides a kind of display device, which includes flexible screen body, flexible screen body has unwound state and winding state, flexible screen body has display side and non-display side, the non-display side of flexible screen body is equipped with support assembly, for providing support for flexible screen body, and for the flexible screen body in unwound state provides support.It needs to be explained that the support assembly structure for being able to support the flexible screen body of winding and unwinding is prior art in the art, and will not be specifically introduced here.

[0049] Flexible screen body includes at least one winding end, part of flexible screen body is selectively unwound or retracted and wound on winding assembly by winding end. Among them, the structure of winding assembly is prior art in the art, such as winding structure equipped with reset torsional spring, etc., and will not be specifically introduced here.

[0050] After flexible screen body is unwound and wound frequently, the two side edges of flexible screen body in width direction are prone to wrinkle and crack problems.

[0051] In view of this, as Figures 1 to 4The display device provided by the embodiment of the utility model also includes two side edge protection assemblies 2 respectively arranged at the two sides of the width direction of the flexible screen body 1, the side edge protection assembly 2 includes a first movable part 21 and a second movable part 22, the first movable part 21 is movably connected to the flexible screen body 1 along the length direction of the flexible screen body 1, the second movable part 22 is movably connected to the first movable part 21 and the flexible screen body 1 along the length direction of the flexible screen body 1, the first movable part 21 and the second movable part 22 are both magnetic structures, and at least one of the magnetic structures in the first movable part 21 and the second movable part 22 is an electromagnetic structure.

[0052] When the flexible screen body 1 is switched from the unwound state to the rolled-up state, the electromagnetic structure forms an attractive force between the first movable part 21 and the second movable part 22 along the length direction of the flexible screen body 1; when the flexible screen body 1 is switched from the rolled-up state to the unwound state, the electromagnetic structure forms a repulsive force between the first movable part 21 and the second movable part 22 along the length direction of the flexible screen body 1. In other words, the current flow direction of the electromagnetic structure when the flexible screen body 1 is switched to the rolled-up state is opposite to the current flow direction of the electromagnetic structure when the flexible screen body 1 is switched to the unwound state.

[0053] In the process of switching the flexible screen body 1 from the unwound state to the rolled-up state, the flexible screen body 1 moves relative to the first movable part 21 along the length direction of the flexible screen body 1, and the flexible screen body 1 moves relative to the second movable part 22 along the length direction of the flexible screen body 1, so that the flexible screen body 1 is gradually rolled up; at the same time, the electromagnetic structure is powered on, so that an attractive force is formed between the first movable part 21 and the second movable part 22 along the length direction of the flexible screen body 1, and this attractive force causes the second movable part 22 to move relative to the first movable part 21 along the length direction of the flexible screen body 1 and approach each other, thereby reducing the length of the flexible screen body 1 that is not rolled up after the rolling-up is completed.

[0054] In the process of switching the flexible screen body 1 from the rolled-up state to the unwound state, the flexible screen body 1 moves relative to the first movable part 21 along the length direction of the flexible screen body 1, and the flexible screen body 1 moves relative to the second movable part 22 along the length direction of the flexible screen body 1, so that the flexible screen body 1 is gradually unwound; at the same time, the electromagnetic structure is powered on, so that a repulsive force is formed between the first movable part 21 and the second movable part 22 along the length direction of the flexible screen body 1, and this repulsive force causes the second movable part 22 to move relative to the first movable part 21 along the length direction of the flexible screen body 1 and move away from each other, thereby completely unwinding the flexible screen body 1.

[0055] No matter whether the flexible screen body 1 is in the unwound state or in the rolled-up state, the first movable part 21 and the second movable part 22 are not rolled up, that is, there is always part of the flexible screen body 1 that is not rolled up, but the two side edges of the flexible screen body 1 in the width direction that is not rolled up are always covered by the first movable part 21 and the second movable part 22.

[0056] No matter whether the flexible screen body 1 is switched between the unfolded state and the rolled-up state or is kept in any one of the unfolded state and the rolled-up state, the side protection assembly 2 can always provide support for the two side edges of the flexible screen body 1 in the width direction which is not rolled up, plays a role of protecting the flexible screen body 1, reduces the probability of wrinkles and cracks of the flexible screen body 1 in the process of frequently unfolding and rolling up the flexible screen body 1, and prolongs the service life of the flexible screen body 1.

[0057] Further, for the convenience of description, the magnetic structure included in the first movable part 21 is referred to as a first magnetic structure, the magnetic structure included in the second movable part 22 is referred to as a second magnetic structure, one of the first magnetic structure and the second magnetic structure is an electromagnetic structure, and the other is a ferromagnetic structure. Taking the example that the first magnetic structure is the electromagnetic structure and the second magnetic structure is the ferromagnetic structure, the first magnetic structure can also be the ferromagnetic structure and the second magnetic structure can also be the electromagnetic structure. The first magnetic structure and the second magnetic structure can also both be the electromagnetic structure. It should be noted that the ferromagnetic structure refers to a common iron block, cobalt block, nickel block, cobalt-iron alloy block and other ferromagnetic material pieces that can be attracted by a magnet, and the electromagnetic structure refers to a structure that can attract or repel the ferromagnetic structure when electrified, which is prior art in the field and will not be specifically introduced here.

[0058] Further, as shown in Figures 1 to 4 The first movable part 21 and the second movable part 22 are both provided in plurality, the plurality of first movable parts 21 are arranged in sequence along the length direction of the flexible screen body 1, and one second movable part 22 is provided between any two adjacent first movable parts 21; the second movable part 22 and one of the first movable parts 21 adjacent thereto are movably connected along the length direction of the flexible screen body 1; and the second movable part 22 and the other first movable part 21 adjacent thereto are fixedly connected.

[0059] Specifically, the first movable part 21 is provided with a first receiving groove on the side facing the flexible screen body 1 along the width direction of the flexible screen body 1, the first receiving groove is provided in a penetrating manner along the length direction of the flexible screen body 1, the second movable part 22 is provided with a second receiving groove on the side facing the flexible screen body 1 along the width direction of the flexible screen body 1, the second receiving groove is provided in a penetrating manner along the length direction of the flexible screen body 1, the second movable part 22 is movably provided in the first receiving groove along the length direction of the flexible screen body 1, and the flexible screen body 1 is movably provided in the second receiving groove along the length direction of the flexible screen body 1.

[0060] In the process of moving the second movable part 22 relative to the first movable part 21 along the length direction of the flexible screen body 1, the second movable part 22 always provides support for the flexible screen body 1 to protect the side edges of the flexible screen body 1 in the width direction from being damaged. In addition, since the side edges of the flexible screen body 1 in the width direction are covered in the second receiving groove by the second movable part 22, when the display device falls accidentally, the two side edges of the flexible screen body 1 in the width direction will not be directly hit, and at this time, the second movable part 22 and the first movable part 21 also play a role in protecting the side edges of the flexible screen body 1 in the width direction from being hit.

[0061] Further, as shown in Figure 4 , when the flexible screen body 1 is in the rolled state, the two adjacent first movable parts 21 abut along the length direction of the flexible screen body 1. In this way, when the flexible screen body 1 is in the rolled state, the two side edges of the flexible screen body 1 in the width direction that are not rolled are all covered in the second receiving groove by the first movable part 21, and when the display device falls accidentally, the two side edges of the flexible screen body 1 in the width direction will not be hit, and at this time, the first movable part 21 plays a role in protecting the side edges of the flexible screen body 1 in the width direction from being hit.

[0062] Specifically, one end of the second movable part 22 is fixedly connected to one of the two adjacent first movable parts 21, and the other end is movably connected to the first receiving groove of the other first movable part 21 along the length direction of the flexible screen body 1. When the flexible screen body 1 is in the rolled state, one end of the second movable part 22 is completely received in the first receiving groove on the first movable part 21 to which it is movably connected. In this way, when the flexible screen body 1 is in the rolled state, the two adjacent first movable parts 21 can abut along the length direction of the flexible screen body 1.

[0063] As shown in Figure 3 and Figure 4 , in order to reduce the noise generated by the collision of the two adjacent second movable parts 22 when the flexible screen body 1 switches to the rolled state, in some other embodiments, at least one of the two adjacent first movable parts 21 is provided with an elastic buffer 23 facing the other first movable part 21 along the length direction of the flexible screen body 1, and when the flexible screen body 1 is in the rolled state, the elastic buffer 23 is clamped between the two adjacent first movable parts 21 along the length direction of the flexible screen body 1.

[0064] For example, in two adjacent first movable parts 21, an elastic buffer 23 is disposed on the side of one of the first movable parts 21 facing the other along the length direction of the flexible screen body 1. Under the attraction between the first movable parts 21 and the second movable parts 22, the first movable parts 21 and the second movable parts 22 move closer to each other along the length direction of the flexible screen body 1. In the two adjacent first movable parts 21, the first movable part 21 without the elastic buffer 23 collides with the elastic buffer 23, causing the elastic buffer 23 to undergo elastic deformation, thereby mitigating the impact when the flexible screen body 1 switches to the retracted state, and playing a role in shock absorption and buffering.

[0065] In other embodiments, elastic buffer members 23 may also be provided on the side of any one of the two adjacent first active parts 21 facing the other first active part 21 along the length direction of the flexible screen body 1.

[0066] It should be noted that the elastic buffer 23 can be any structure that can provide cushioning and shock absorption, such as a rubber pad, and is not specifically limited here.

[0067] In other embodiments, the elastic buffer 23 can also adopt other structures. Specifically, the elastic buffer 23 includes a second elastic part and a buffer part. The first movable part 21 has an annular groove on its end face facing the adjacent first movable part 21 along the length direction of the flexible screen 1. The second elastic part is fixed to the bottom wall of the annular groove. The buffer part is connected to the second elastic part. One end of the buffer part is placed in the annular groove, and the other end of the buffer part can move in and out of the annular groove along the length direction of the flexible screen 1. When the flexible screen 1 is in the unfolded state, the end of the buffer part away from the second elastic part extends out of the annular groove along the length direction of the flexible screen 1. During the winding of the flexible screen 1, the first movable part 21 near the buffer part first touches the buffer part. During the continued winding of the flexible screen 1, the second elastic part is continuously compressed. The second elastic part can be a spring, etc., and the buffer part can be a flexible pad, rubber pad, sponge pad, etc., which can play a buffering and shock-absorbing role. Alternatively, an annular groove can be provided at each end of the length direction of the first movable part 21, and an elastic buffer 23 can be provided for each annular groove.

[0068] like Figure 3 and Figure 4 As shown, further, two elastic support members 24 are fixedly arranged at intervals along the thickness direction of the flexible screen body 1 in the first storage groove; when the flexible screen body 1 is in the rolled-up state, the second movable part 22 is clamped between the two elastic support members 24 along the thickness direction of the flexible screen body 1; when the flexible screen body 1 is in the unfolded state, the flexible screen body 1 is clamped between the two elastic support members 24 along its own thickness direction, and the second movable part 22 is located on one side of the adjacent elastic support member 24 in the length direction of the flexible screen body 1.

[0069] As shown in Figure 4 , when the flexible screen body 1 is in the rolled state, the two sides of the flexible screen body 1 in the width direction that are not rolled are all covered in the first movable part 21, so that the two sides of the flexible screen body 1 in the width direction are not exposed, and at this time the elastic support 24 is extruded by the first movable part 21 and is in the compressed state; during the process of unfolding the flexible screen body 1, the first movable part 21 and the second movable part 22 adjacent thereto move away from each other, and after the flexible screen body 1 is completely unfolded, the second movable part 22 is separated from the elastic support 24 along the length direction of the flexible screen body 1, and the elastic support 24 recovers the deformation, so that part of the flexible screen body 1 is covered in the second movable part 22 and another part of the flexible screen body 1 is covered between the two elastic supports 24, so that when the flexible screen body 1 is in the unfolded state, part of the two sides of the flexible screen body 1 in the width direction is covered in the second movable part 21 and another part is covered in the first movable part 21. In this way, it is realized that no matter whether the flexible screen body 1 is in the unfolded state or in the rolled state, the two sides of the flexible screen body 1 in the width direction can be supported and protected by the first movable part 21 and the second movable part 22.

[0070] Further, as shown in Figures 3 to 6 , the first receiving groove is fixed with an elastic limiting piece 25 on the inner wall of the flexible screen body 1 along the width direction of the flexible screen body 1; when the flexible screen body 1 is in the rolled state, the second movable part 22 is clamped between the elastic limiting piece 25 and the flexible screen body 1 along the width direction of the flexible screen body 1; when the flexible screen body 1 is in the unfolded state, the elastic limiting piece 25 abuts against the flexible screen body 1 along the width direction of the flexible screen body 1, and the second movable part 22 is located on one side of the adjacent elastic limiting piece 25 in the length direction of the flexible screen body 1.

[0071] When the second movable part 22 is separated from the two elastic supports 24 along the length direction of the flexible screen body 1, the flexible screen body 1 is clamped between the elastic limiting pieces 25 on both sides of the flexible screen body 1 in the width direction, so as to avoid that when the flexible screen body 1 in the unfolded state falls accidentally, the bottom wall of the first receiving groove and the side surface of the flexible screen body 1 in the width direction collide hard, thereby protecting the flexible screen body 1.

[0072] Further, as shown in Figure 3 and Figure 4 , the elastic support 24 has a first end and a second end oppositely arranged along the length direction of the flexible screen body 1, and the first end of each elastic support 24 arranged in the same first receiving groove has a first guide surface 241 facing the other elastic support 24, and the distance between the two first guide surfaces 241 along the thickness direction of the flexible screen body 1 gradually increases from the second end to the first end.

[0073] In the process of rolling the flexible screen body 1, the first guide surface 241 guides the second movable part 22, so that the second movable part 22 enters between the two elastic supporting members 24 in the same first receiving groove.

[0074] Further, as shown in Figure 3 and Figure 4 , the elastic limiting member 25 has an end part one and an end part two oppositely arranged along the length direction of the flexible screen body 1, the end part one faces a side in the thickness direction of the flexible screen body 1 and forms a second guide surface, and the second guide surface gradually moves away from the center axis extending in the length direction of the flexible screen body 1 along the width direction of the flexible screen body 1 from the direction of the end part two to the end part one.
