[0009] When the flexible screen body is switched to a retracted state, the electromagnetic structure forms an attractive force between the first movable part and the second movable part along the length direction of the flexible screen body; when the flexible screen body is switched to an unfolded state, the electromagnetic structure forms a repulsive force between the first movable part and the second movable part along the length direction of the flexible screen body.

[0010] As an implementation scheme of the above display device, there are multiple first movable parts and multiple second movable parts, and the multiple first movable parts are arranged in sequence along the length direction of the flexible screen body, and one second movable part is provided between two adjacent first movable parts;

[0017] As an implementation scheme of the above-mentioned display device, the flexible screen body has the rolled-up state. When the flexible screen body is in the rolled-up state, at least one end of the second movable part is received in the first receiving groove on the first movable part movably connected to the second movable part along the length direction of the flexible screen body.

[0018] As a feasible implementation scheme of the above-mentioned display device, two elastic support members arranged at intervals along the thickness direction of the flexible screen body are fixed in the first storage groove; when the flexible screen body is in a rolled-up state, the second movable part is clamped between the two elastic support members along the thickness direction of the flexible screen body; when the flexible screen body is in an unfolded state, the flexible screen body is clamped between the two elastic support members along its own thickness direction, and the second movable part is located on one side of the adjacent elastic support member in the length direction of the flexible screen body.

[0019] As an implementation scheme for the above-mentioned display device, the first storage groove is fixedly provided with an elastic limiter along the width direction of the flexible screen body facing the inner wall of the flexible screen body; when the flexible screen body is in a rolled-up state, the second movable part is clamped between the elastic limiter and the flexible screen body along the width direction of the flexible screen body; when the flexible screen body is in an unfolded state, the elastic limiter abuts against the flexible screen body along the width direction of the flexible screen body, and the second movable part is located on one side of the adjacent elastic limiter in the length direction of the flexible screen body.

[0020] As an implementation scheme of the above display device, the elastic support member has a first end and a second end arranged opposite to each other along the length direction of the flexible screen body, and in the two elastic support members arranged in the same first receiving groove, the first end of each elastic support member has a first guide surface facing the other elastic support member, and the distance between the two first guide surfaces along the thickness direction of the flexible screen body gradually increases from the second end to the first end;

[0021] And / or, the elastic limit member has an end one and an end two which are relatively arranged along the length direction of the flexible screen body, and a second guide surface is formed on one side of the end facing the thickness direction of the flexible screen body, and from the end two to the end one, the second guide surface gradually moves away from the central axis extending in the length direction of the flexible screen body along the width direction of the flexible screen body.

[0022] As an implementation scheme of the above display device, the elastic support member and the elastic limit member each include a support portion placed in the first receiving groove, and a plurality of first elastic portions spaced apart along the length direction of the flexible screen body, an inner wall of the first receiving groove is provided with mounting grooves corresponding to the plurality of first elastic portions one by one, one end of the first elastic portion is fixedly arranged in the mounting groove, and the other end of the first elastic portion is fixedly connected to the support portion;

[0025] The beneficial effects of the present invention are as follows: in the process of switching the flexible screen from the unfolded state to the rolled-up state, the flexible screen moves relative to the first movable part along the length direction of the flexible screen, and the flexible screen moves relative to the second movable part along the length direction of the flexible screen, so that the flexible screen is gradually rolled up; at the same time, the electromagnetic structure is energized to form an attractive force along the length direction of the flexible screen between the first movable part and the second movable part, and this attractive force makes the second movable part approach each other relative to the first movable part along the length direction of the flexible screen, thereby reducing the length of the flexible screen that has not been rolled up after the rolling is completed.

[0026] In the process of switching the flexible screen from a rolled-up state to an unfolded state, the flexible screen moves relative to the first movable part along the length direction of the flexible screen, and the flexible screen moves relative to the second movable part along the length direction of the flexible screen, so that the flexible screen is gradually unfolded; at the same time, the electromagnetic structure is energized to form a repulsive force between the first movable part and the second movable part along the length direction of the flexible screen, and this repulsive force causes the second movable part to move away from the first movable part along the length direction of the flexible screen, thereby fully unfolding the flexible screen.

[0027] Regardless of whether the flexible screen is switching between the unfolded state and the rolled-up state, or remains in any of the unfolded state and the rolled-up state, the side protection component can always provide support for the two side edges in the width direction of the flexible screen that is not rolled up, thereby protecting the flexible screen, reducing the probability of wrinkles and cracks on the flexible screen during frequent unfolding and rolling up of the flexible screen, and extending the service life of the flexible screen.

[0047] Embodiment 1

[0048] An embodiment of the present invention provides a display device, which includes a flexible screen body, the flexible screen body has an unfolded state and a rolled-up state, the flexible screen body has a display side and a non-display side, and the non-display side of the flexible screen body is provided with a support component for providing support for the flexible screen body and for providing support for the flexible screen body in the unfolded state. It should be noted that the support component structure for supporting the flexible screen body that can be rolled up and unfolded is a prior art in the art and will not be described in detail here.

[0049] The flexible screen includes at least one winding end, and part of the flexible screen can be selectively unfolded or retracted by the winding end and wound on the winding assembly. The structure of the winding assembly is the prior art in the art, such as a winding structure equipped with a reset torsion spring, etc., which will not be described in detail here.

[0050] After the flexible screen is frequently unfolded and rolled up, wrinkles and cracks are very likely to appear on both sides of the flexible screen in the width direction.

[0051] In view of this, if Figures 1 to 4As shown, the display device provided by an embodiment of the present invention also includes two side protection components 2 respectively arranged on both sides of the width direction of the flexible screen body 1, the side protection component 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 first movable part 21 and the second movable part 22 is an electromagnetic structure.

[0052] When the flexible screen body 1 switches from the unfolded state to the reeled 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 switches from the reeled state to the unfolded 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 switches to the reeled state is opposite to the current flow direction of the electromagnetic structure when the flexible screen body 1 switches to the unfolded state.

[0053] In the process of switching the flexible screen body 1 from the unfolded 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 energized to form an attractive force along the length direction of the flexible screen body 1 between the first movable part 21 and the second movable part 22, and this attractive force makes the second movable part 22 approach each other relative to the first movable part 21 along the length direction of the flexible screen body 1, thereby reducing the length of the flexible screen body 1 that has not been rolled up after the rolling is completed.

[0054] In the process of switching the flexible screen body 1 from the rolled-up state to the unfolded 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 unfolded; at the same time, the electromagnetic structure is energized to form a repulsive force along the length direction of the flexible screen body 1 between the first movable part 21 and the second movable part 22, and this repulsive force causes the second movable part 22 to move away from each other relative to the first movable part 21 along the length direction of the flexible screen body 1, so that the flexible screen body 1 is fully unfolded.

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

[0056] Regardless of whether the flexible screen 1 is switching between the unfolded state and the retracted state, or remains in any of the unfolded state and the retracted state, the side protection assembly 2 can always provide support for the two side edges in the width direction of the flexible screen 1 that is not retracted, thereby protecting the flexible screen 1, reducing the probability of wrinkles and cracks on the flexible screen 1 during frequent unfolding and retracting of the flexible screen 1, and extending the service life of the flexible screen 1.

[0057] Further, for the convenience of description, the magnetic structure included in the first movable part 21 is recorded as the first magnetic structure, and the magnetic structure included in the second movable part 22 is recorded as the 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. For example, the first magnetic structure is an electromagnetic structure and the second magnetic structure is a ferromagnetic structure. The first magnetic structure can also be a ferromagnetic structure and the second magnetic structure can be an electromagnetic structure. The first magnetic structure and the second magnetic structure can also be electromagnetic structures. It should be noted that the ferromagnetic structure refers to a common ferromagnetic material part that can be adsorbed by a magnet, such as an iron block, a cobalt block, a nickel block, a cobalt-iron alloy block, etc. The electromagnetic structure refers to a structure that can attract or repel the ferromagnetic structure when power is turned on. This is a prior art in the field and will not be described in detail here.

[0058] Furthermore, if Figures 1 to 4 As shown, there are multiple first movable parts 21 and second movable parts 22, and the multiple first movable parts 21 are arranged in sequence along the length direction of the flexible screen body 1, and a second movable part 22 is provided between two adjacent first movable parts 21; the second movable part 22 and one of the first movable parts 21 adjacent to it are movably connected along the length direction of the flexible screen body 1; the second movable part 22 and another first movable part 21 adjacent to it are fixedly connected.

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

[0060] During the movement of the second movable portion 22 relative to the first movable portion 21 along the length direction of the flexible screen body 1, the second movable portion 22 always provides support for the flexible screen body 1 to protect the side edges in the width direction of the flexible screen body 1 that pass through the second storage groove. In addition, since the side edges in the width direction of the flexible screen body 1 are covered by the second movable portion 22 in the second storage groove, when the display device falls accidentally, the two side edges in the width direction of the flexible screen body 1 will not be directly hit. At this time, the second movable portion 22 and the first movable portion 21 also play a role in preventing the side edges in the width direction of the flexible screen body 1 from being hit.

[0061] Furthermore, if Figure 4 As shown, when the flexible screen body 1 is in the rolled-up state, two adjacent first movable parts 21 abut against each other along the length direction of the flexible screen body 1. With such a configuration, when the flexible screen body 1 is in the rolled-up state, both sides of the flexible screen body 1 in the width direction that are not rolled up are completely covered by the first movable parts 21 in the second storage groove, and when the display device is accidentally dropped, both sides of the flexible screen body 1 in the width direction will not be hit, and at this time, the first movable parts 21 play a role in preventing the side sides of the flexible screen body 1 in the width direction from being hit.

[0062] Specifically, one end of the second movable portion 22 is fixedly connected to one of the two adjacent first movable portions 21, and the other end is movably arranged in the first receiving groove of the other first movable portion 21 along the length direction of the flexible screen body 1. When the flexible screen body 1 is in the rolled-up state, one end of the second movable portion 22 is completely received in the first receiving groove on the first movable portion 21 movably connected thereto. In this way, when the flexible screen body 1 is in the rolled-up state, the two adjacent first movable portions 21 can abut against each other along the length direction of the flexible screen body 1.

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

[0064] Exemplarily, in two adjacent first movable parts 21, the elastic buffer 23 is arranged on the side of one of the first movable parts 21 facing the other first movable part 21 along the length direction of the flexible screen body 1. Under the attraction between the first movable part 21 and the second movable part 22, the first movable part 21 and the second movable part 22 approach each other along the length direction of the flexible screen body 1, and the first movable part 21 without the elastic buffer 23 collides with the elastic buffer 23, so that the elastic buffer 23 is elastically deformed, thereby alleviating the impact when the flexible screen body 1 switches to the reeled state, playing a role of shock absorption and buffering.

[0065] In other embodiments, an elastic buffer 23 may be provided on the side of any one of two adjacent first movable parts 21 facing the other first movable 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 achieve buffering and shock absorbing effects, such as a rubber pad, and is not specifically limited here.

[0067] In other embodiments, the elastic buffer 23 may also adopt other structures. Specifically, the elastic buffer 23 includes a second elastic part and a buffer part. The first movable part 21 is provided with an annular groove on the end face of the first movable part 21 adjacent to it along the length direction of the flexible screen body 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. The other end of the buffer part can move in and out of the annular groove along the length direction of the flexible screen body 1. When the flexible screen body 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 body 1. In the process of rolling up the flexible screen body 1, the first movable part 21 close to the buffer part first hits the buffer part. In the process of continuing to roll up the flexible screen body 1, the second elastic part is continuously squeezed. The above-mentioned second elastic part can be a spring, etc., and the buffer part can be a structure that can play a buffering and shock absorbing effect, such as a flexible gasket, a rubber pad, a sponge pad, etc. It is also possible to set an annular groove at each end of the length direction of the first movable part 21, and each annular groove is equipped with an elastic buffer 23.

[0068] like Figure 3 and Figure 4As shown, when the second movable part 22 separates from the two elastic support members 24 along the length direction of the flexible screen body 1, in order to avoid the flexible screen body 1 between the two second movable parts 22 being unsupported, further, two elastic support members 24 arranged at intervals along the thickness direction of the flexible screen body 1 are fixed in the first storage groove; when the flexible screen body 1 is in a 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 an 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] like Figure 4 As shown, when the flexible screen body 1 is in a rolled-up state, both side edges of the flexible screen body 1 in the width direction that are not rolled up are completely covered in the first movable part 21, so that the both side edges of the flexible screen body 1 in the width direction that are not rolled up will not be exposed, and at this time, the elastic support member 24 is squeezed by the first movable part 21 and is in a compressed state; and in 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 fully unfolded, the second movable part 22 separates from the elastic support member 24 along the length direction of the flexible screen body 1, and the elastic support member 24 restores its deformation, so that part of the flexible screen body 1 is covered in the second movable part 22, and the other part of the flexible screen body 1 is covered between the two elastic support members 24, so that when the flexible screen body 1 is in the unfolded state, part of the both side edges of the flexible screen body 1 in the width direction are covered in the second movable part 22, and the other part is covered in the first movable part 21. With such an arrangement, both side edges 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 regardless of whether the flexible screen body 1 is in the unfolded state or the rolled-up state.

[0070] Furthermore, if Figures 3 to 6 As shown, the first receiving groove is fixedly provided with an elastic limit member 25 along the width direction of the flexible screen body 1 facing the inner wall of the flexible screen body 1; when the flexible screen body 1 is in a rolled-up state, the second movable portion 22 is clamped between the elastic limit member 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 an unfolded state, the elastic limit member 25 abuts against the flexible screen body 1 along the width direction of the flexible screen body 1, and the second movable portion 22 is located on one side of the adjacent elastic limit member 25 in the length direction of the flexible screen body 1.

[0071] When the second movable part 22 separates from the two elastic supporting parts 24 along the length direction of the flexible screen body 1, the flexible screen body 1 is clamped between the elastic limiting parts 25 on both sides of the width direction of the flexible screen body 1 to prevent the bottom wall of the first storage groove and the side surface of the flexible screen body 1 in the width direction from having a hard collision when the flexible screen body 1 in the unfolded state accidentally falls, thereby protecting the flexible screen body 1.

[0072] Furthermore, if Figure 3 and Figure 4 As shown, the elastic support member 24 has a first end and a second end that are relatively arranged along the length direction of the flexible screen body 1. Among the two elastic support members 24 arranged in the same first receiving groove, the first end of each elastic support member 24 has a first guide surface 241 facing the other elastic support member 24. From the second end to the first end, the distance between the two first guide surfaces 241 along the thickness direction of the flexible screen body 1 gradually increases.

[0073] During the process of rolling up the flexible screen body 1 , the first guide surface 241 is used to guide the second movable portion 22 , so that the second movable portion 22 can enter between the two elastic support members 24 located in the same first receiving groove.

[0074] Furthermore, if Figure 3 and Figure 4 As shown, the elastic limit member 25 has an end one and an end two which are relatively arranged along the length direction of the flexible screen body 1, and a second guide surface is formed on one side of the end facing the thickness direction of the flexible screen body 1. From the end two to the end one, the second guide surface gradually moves away from the central axis extending in the length direction of the flexible screen body 1 along the width direction of the flexible screen body 1.

[0075] During the process of rolling up the flexible screen body 1 , the second guide surface is used to guide the second movable portion 22 , so that the second movable portion 22 can enter between the flexible screen body 1 and the elastic limiting member 25 .

[0076] Furthermore, if Figures 3 to 6 As shown, the elastic support member 24 and the elastic limit member 25 both include a support portion 261 and a plurality of first elastic portions 262. The inner wall of the first receiving groove is provided with a plurality of mounting grooves corresponding to the plurality of first elastic portions 262. A first elastic portion 262 is fixed in each mounting groove. One end of the first elastic portion 262 is fixed in the corresponding mounting groove, and the other end of the first elastic portion 262 is fixedly connected to the support portion 261 so that the support portion 261 selectively abuts against the second movable portion 22 or the flexible screen body 1.

[0077] Specifically, when the flexible screen body 1 is in the rolled-up state, the second movable portion 22 is sandwiched between the support portions 261 of the two elastic support members 24 along the thickness direction of the flexible screen body 1, and the second movable portion 22 abuts against the support portion 261 of the elastic stop member 25 on the side facing away from the flexible screen body 1 along the width direction of the flexible screen body 1, and the first elastic portion 262 is in a compressed state, and the support portion 261 is pressed against the inner wall of the first storage groove. When the flexible screen body 1 is in the unfolded state, the second movable portion 22 moves along the length direction of the flexible screen body 1 to one side of the support portion 261 in the length direction of the flexible screen body 1, and the support portion 261 moves away from the inner wall of the first storage groove opposite to it under the action of the first elastic portion 262.

[0078] The display device provided by the present invention is used as a roll-up screen, such as an advertising screen, a television screen, a stage screen, a mobile phone screen, etc.

[0079] The embodiment of the present invention further provides an electronic device, including the above-mentioned display device, to improve the service life of the electronic device.

[0081] The difference between this embodiment and the first embodiment is that Figures 7 to 10 As shown, the second movable portion 22 and one of the first movable portions 21 adjacent thereto are movably connected along the length direction of the flexible screen body 1 , and the second movable portion 22 and another first movable portion 21 adjacent thereto are movably connected along the length direction of the flexible screen body 1 .

[0082] During the process of rolling up and unfolding the flexible screen body 1 , the second movable portion 22 moves along the length direction of the flexible screen body 1 simultaneously relative to the two first movable portions 21 on both sides of the second movable portion 22 .

[0083] Embodiment 3

[0084] The difference between this embodiment and the first embodiment is that Fig.11 and Fig.12 As shown, the elastic support member 24 and the elastic limiting member 25 are an integrally formed structural member. Such an arrangement facilitates the installation of the integrally formed structural member formed by the elastic support member 24 and the elastic limiting member 25 in the first receiving groove.

[0085] Specifically, the integrally formed structural part is adhered and fixed to the inner wall of the first receiving groove, and the integrally formed structural part has a U-shaped opening, one end of the U-shaped opening is opened toward one side in the width direction of the flexible screen body 1, and the U-shaped opening is set through along the length direction of the flexible screen body 1, and one end of the U-shaped opening along the length direction of the flexible screen body 1 is a conical opening, so that the inner wall of the conical opening forms the above-mentioned first guide surface 241 and the second guide surface. The integrally formed structure is rubber. Exemplarily, the integrally formed structural part is a rubber pad.

[0086] Furthermore, the elastic support member 24 and the elastic stop member 25 are both provided with a plurality of deformation holes. In this way, during the process of rolling up the flexible screen body 1, the elastic support member 24 and the elastic stop member 25 are squeezed and deformed, and the provision of the deformation holes facilitates the elastic deformation of the elastic support member 24 and the elastic stop member 25, thereby reducing the friction resistance when the second movable part 22 moves relative to the first movable part along the length direction of the flexible screen body 1.
