[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0051] In the related art, terminal devices with foldable displays include multiple support plates, each of which requires a linkage and synchronization structure. On the one hand, the presence of these linkage and synchronization structures causes the foldable display to occupy a significant amount of internal space in the terminal device, resulting in a thicker terminal device. On the other hand, these linkage and synchronization structures increase the weight of the foldable display, which in turn increases the weight of the terminal device. Furthermore, to reduce the number of linkage and synchronization structures and thus the weight of the terminal device, the number of support plates is often reduced, resulting in poor support for the display panel of the foldable display.

[0052] A foldable display screen according to an embodiment of the present invention includes a display panel and a support assembly, wherein at least a portion of the display panel is disposed on the support assembly.

[0053] Specifically, the support assembly is provided on the non-displaying side of the display panel. The entire display panel can be provided on the support assembly, in which case the support assembly supports the display panel and enables folding of the display panel. Of course, only a portion of the display panel can be provided on the support assembly, in which case the support assembly supports that portion of the display panel and enables folding of that portion of the display panel.

[0054] The foldable display screen can be a display screen of a mobile phone, a tablet computer display screen, or other terminal device. The display panel is a bendable flexible display panel.

[0055] The support assembly according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0056] like Figures 1 to 5 As shown, a support assembly 100 according to an embodiment of the present invention includes a first support member 1, a second support member 2, and a third support member 3. The first support member 1 is rotatably disposed on one side of the second support member 2, and the third support member 3 is rotatably disposed on the other side of the second support member 2. The first support member 1 is movable between a first locked position and a first unlocked position. When the first support member 1 is in the first locked position, the first support member 1 can rotate relative to the second support member 2, and the second support member 2 and the third support member 3 are relatively fixed. When the first support member 1 is in the first unlocked position, the second support member 2 can rotate relative to the third support member 3.

[0057] The ability of the first support member 1 to rotate relative to the second support member 2 can be understood as follows: when the display panel needs to be folded, the first support member 1 rotates relative to the second support member 2; when the display panel does not need to be folded, the first support member 1 can rotate relative to the second support member 2, and the first support member 1 may not rotate relative to the second support member 2.

[0058] The second support member 2 can rotate relative to the third support member 3, which can be understood as: when the display panel needs to be folded, the second support member 2 rotates relative to the third support member 3; when the display panel does not need to be folded, the second support member 2 can rotate relative to the third support member 3, and the second support member 2 can also be fixed relative to the third support member 3.

[0059] In order to make the technical solution of the present application easier to understand, the following further describes the technical solution of the present application by taking the arrangement direction of the first support member 1 and the second support member 2 as an example, in which the arrangement direction of the first support member 1 and the second support member 2 is consistent with the left-right direction and the rotation axis of the first support member 1 is consistent with the front-back direction. Figures 1 to 4 shown.

[0060] For example, Figure 1 and Figure 2As shown, the first support member 1 is rotatably disposed on the left side of the second support member 2, and the third support member 3 is rotatably disposed on the right side of the second support member 2. The first support member 1 has a first rotation axis extending in the front-to-back direction, and the second support member 2 has a second rotation axis extending in the front-to-back direction. When the first support member 1 is in the first locked position, the first support member 1 can rotate relative to the second support member 2 about the first rotation axis; when the first support member 1 is in the first unlocked position, the second support member 2 can rotate relative to the third support member 3 about the second rotation axis.

[0061] The usage process of the foldable display screen according to the embodiment of the present invention is as follows:

[0062] When the foldable display needs to be bent and folded, first, the first support member 1 is positioned in the first locked position. The first support member 1 rotates relative to the second support member 2 about the first rotation axis by a first preset angle, causing the portion of the display panel corresponding to the first support member 1 to bend and fold by the first preset angle. At this point, the second support member 2 and the third support member 3 are fixed relative to each other, with the second and third support members 2 and 3 providing stable support for the corresponding portions of the display panel (the portion corresponding to the second support member 2 and the portion corresponding to the third support member 3). Then, the first support member 1 is moved to the first unlocked position. The second support member 2 rotates relative to the third support member 3 about the second rotation axis by a second preset angle, causing the portion of the display panel corresponding to the second support member 2 to bend and fold by a second preset angle. This second preset angle can be equal to the first preset angle. The second support member 2 then causes the portion corresponding to the first support member 1 to bend and fold by a further second preset angle relative to the third support member 3, resulting in the portion corresponding to the first support member 1 being bent and folded relative to the third support member 3 by the sum of the first and second preset angles. Finally, folding of at least a portion of the foldable display is completed.

[0063] When the foldable display needs to be unfolded, first, the first support member 1 is moved to the first unlocked position, and the second support member 2 is rotated relative to the third support member 3 around the second rotation axis by a second preset angle, so that the portion of the display panel corresponding to the second support member 2 is unfolded, and the second support member 2 is used to drive the portion corresponding to the first support member 1 to rotate relative to the third support member 3 by the second preset angle. Then, the first support member 1 is moved to the first locked position. At this time, the second support member 2 and the third support member 3 are relatively fixed, and the second support member 2 and the third support member 3 are used to stably support the corresponding portions of the display panel (the portions corresponding to the second support member 2 and the third support member 3). In addition, the first support member 1 is rotated relative to the second support member 2 around the first rotation axis by a first preset angle, so that the portion of the display panel corresponding to the first support member 1 is unfolded. Finally, the unfolding of at least a portion of the foldable display is completed.

[0064] The support assembly 100 of the embodiment of the present invention only requires the formation of rotational pairs between the first support member 1 and the second support member 2, and between the second support member 2 and the third support member 3, to enable the first support member 1 to rotate relative to the second support member 2, and the second support member 2 to rotate relative to the third support member 3. Furthermore, stop structures are provided between the first support member 1, the second support member 2, and the third support member 3, so that when the first support member 1 is in the first locked position, the first support member 1 can rotate relative to the second support member 2, while the second support member 2 and the third support member 3 are relatively fixed; and when the first support member 1 is in the first unlocked position, the second support member 2 can rotate relative to the third support member 3. This eliminates the need for interlocking and synchronization structures between each support member. Compared to related art designs, the support assembly 100 is significantly smaller in size and weight, thereby reducing the thickness and weight of the foldable display, and thus the thickness and weight of the terminal device incorporating the foldable display, facilitating a slimmer and lighter design for the terminal device incorporating the foldable display.

[0065] Therefore, the support assembly 100 of the embodiment of the present invention has advantages such as small size and light weight. The foldable display screen having the support assembly 100 of the embodiment of the present invention has advantages such as small size and light weight.

[0066] In addition, after the volume and weight of the support assembly are reduced, the number of support members can be appropriately increased so that the support assembly can better support the display panel, which is beneficial to improving the user experience.

[0067] In some embodiments, as Figures 1 to 5 As shown, the support assembly 100 further includes a fourth support member 4, which is rotatably disposed on a side of the third support member 3 away from the second support member 2. When the first support member 1 is in the first locking position, the third support member 4 is fixed relative to the fourth support member 4.

[0068] The second support member 2 is movable between a second locked position and a second unlocked position. When the second support member 2 is in the second locked position, the first support member 1 is in the first unlocked position, and the third support member 3 is fixed relative to the fourth support member 4. When the second support member 2 is in the second unlocked position, the third support member 3 can rotate relative to the fourth support member 4.

[0069] The ability of the third support member 3 to rotate relative to the fourth support member 4 can be understood as: when the display panel needs to be folded, the third support member 3 rotates relative to the fourth support member 4; when the display panel does not need to be folded, the third support member 3 can rotate relative to the fourth support member 4, and the third support member 3 can also be fixed relative to the fourth support member 4.

[0070] like Figure 1 and Figure 2As shown, the fourth support member 4 is rotatably disposed on the right side of the third support member 3. The third support member 3 has a third rotation axis extending in the front-to-back direction. When the second support member 2 is in the second locked position and the first support member 1 is in the first unlocked position, the second support member 2 can rotate relative to the third support member 3 about the second rotation axis. When the second support member 2 is in the second unlocked position, the third support member 3 can rotate relative to the fourth support member 3 about the third rotation axis.

[0071] When the foldable display needs to be bent and folded, first, the first support member 1 is positioned in the first locking position, so that the portion of the display panel corresponding to the first support member 1 is bent and folded at a first preset angle. At this point, the second support member 2 and the third support member 3, as well as the third support member 3 and the fourth support member 4, are relatively fixed, and the second support member 2, the third support member 3, and the fourth support member 4 provide stable support for the corresponding portions of the display panel (the portion corresponding to the second support member 2, the portion corresponding to the third support member 3, and the portion corresponding to the fourth support member 4).

[0072] Then, the second support member 2 moves to the second locked position, while the first support member 2 is in the first unlocked position, causing the portion of the display panel corresponding to the second support member 2 to bend and fold at the second preset angle. Furthermore, the second support member 2 drives the portion corresponding to the first support member 1 to bend and fold relative to the third support member by the sum of the first and second preset angles. At this point, the third support member 3 and the fourth support member 4 are relatively fixed, and the third and fourth support members 3 and 4 provide stable support for the corresponding portions of the display panel (the portion corresponding to the third support member 3 and the portion corresponding to the fourth support member 4).

[0073] Afterward, the second support member 2 moves to the second unlocked position, and the third support member 3 rotates about the third rotation axis relative to the fourth support member 4 by a third preset angle. This causes the portion of the display panel corresponding to the third support member 3 to bend and fold by the third preset angle, which can be equal to the first preset angle. The third support member 3 then causes the portion corresponding to the second support member 2 to bend and fold by a further third preset angle relative to the fourth support member 4, resulting in the portion corresponding to the second support member 2 being bent and folded relative to the fourth support member 4 by the sum of the second and third preset angles. Simultaneously, the third support member 3 causes the portion corresponding to the first support member 1 to bend and fold by a further third preset angle relative to the fourth support member 4, resulting in the portion corresponding to the first support member 1 being bent and folded relative to the fourth support member 4 by the sum of the first, second, and third preset angles. Finally, folding of at least a portion of the foldable display is completed.

[0074] When the foldable display screen needs to be unfolded, first, the second support member 2 is located in the second unlocked position, and the third support member 3 is rotated around the third rotation axis by a third preset angle relative to the fourth support member 4, so that the part of the display panel corresponding to the third support member 3 is unfolded, and the third support member 3 is used to drive the part corresponding to the second support member 2 to rotate by a third preset angle relative to the fourth support member 4, and the third support member 3 is used to drive the part corresponding to the first support member 1 to rotate by a third preset angle relative to the fourth support member 4.

[0075] Then, the second support member 2 is moved to the second locking position. At this time, the first support member 1 is in the first unlocking position, and the third support member 3 and the fourth support member 4 are relatively fixed. The third support member 3 and the fourth support member 4 are used to stably support the corresponding parts of the display panel (the parts corresponding to the third support member 3 and the fourth support member 4), and the part of the display panel corresponding to the second support member 2 is unfolded, and the part corresponding to the first support member 1 is rotated by a second preset angle relative to the third support member 3. Thereafter, the first support member 1 is moved to the first locking position. At this time, the second support member 2 and the third support member 3 are relatively fixed. The second support member 2 and the third support member 3 are used to stably support the corresponding parts of the display panel (the parts corresponding to the second support member 2 and the third support member 3), and the part of the display panel corresponding to the first support member 1 is unfolded. Finally, the unfolding of at least a portion of the foldable display screen is completed.

[0076] To achieve the bending, folding, and unfolding process of the above-mentioned support assembly 100, it is only necessary to form a rotating pair between the third support member 3 and the fourth support member 4 so that the third support member 3 can rotate relative to the fourth support member 4, and to provide a stop structure between the first support member 1, the second support member 2, the third support member 3, and the fourth support member 4 so that when the second support member 2 is in the second locked position, the third support member 2 is fixed relative to the fourth support member 4. Furthermore, when the second support member 2 is in the second unlocked position, the third support member 3 can rotate relative to the fourth support member 4. Compared with the related art, the volume and weight of the support assembly are further reduced, thereby further reducing the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device with the foldable display, which is conducive to the lightweight design of the terminal device with the foldable display.

[0077] Optionally, the first support member 1 includes a first support body 101 and a first mating portion 102 provided on the first support body 101. The second support member 2 includes a second support body 201 and a second mating portion 202 provided on the second support body 201. The second mating portion 202 is rotatably provided on the first mating portion 102, so that the first support member 1 is rotatably provided on the second support member 2.

[0078] In order to make the technical solution of the present application easier to understand, the following takes the example of the thickness direction of the first support body 1 being consistent with the up-down direction when the display panel is fully unfolded to further describe the technical solution of the present application. Figures 1 to 4 shown.

[0079] For example, Figures 1 to 4 As shown, the first matching portion 102 is provided on the upper surface of the first supporting body 101, and the second matching portion 202 is provided on the upper surface of the second supporting body 201. The display panel is provided on the lower side of the first supporting body 101 and the second supporting body 201, so that the lower surfaces of the first supporting body 101 and the second supporting body 201 are used to support the corresponding parts of the display panel (the parts corresponding to the first supporting body 101 and the parts corresponding to the second supporting body 201).

[0080] Thus, when the foldable display needs to be bent, folded, or unfolded, the first mating portion 102 is rotated relative to the second mating portion 202 to achieve rotation of the first support member 1 relative to the second support member 2. This not only facilitates the rotation of the first support member 1 relative to the second support member 2, but also helps simplify the structure of the first support member 1 and the second support member 2. This helps further reduce the volume and weight of the support assembly 100, further reducing the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device equipped with the foldable display.

[0081] Optionally, the first matching portion 102 overhangs from an edge of the first supporting body 101 in a direction toward the second supporting body 201. The second matching portion 202 overhangs from an edge of the second supporting body 201 in a direction toward the first supporting body 101.

[0082] For example, Figures 1 to 5 As shown, the first matching portion 102 overhangs rightward from the right edge of the first support body 101 , and the second matching portion 202 overhangs leftward from the left edge of the second support body 201 .

[0083] Therefore, the first matching portion 102 and the second matching portion 202 are close to each other and have overlapping parts, which facilitates the matching of the first matching portion 102 and the second matching portion 202, thereby simplifying the structure of the support component 100 and facilitating the assembly of the support component 100.

[0084] Optionally, one of the first mating portion 102 and the second mating portion 202 is a first slider, and the other of the first mating portion 102 and the second mating portion 202 is a first slide. The first slider has a first slide groove 2021 with an opening toward the first slide. A portion of the first slide is slidably disposed in the first slide groove 2021 along the arrangement direction of the first support body 101 and the second support body 201 through the opening of the first slide groove 2021.

[0085] For example, Figure 2 As shown, the first mating portion 102 is a first sliding plate, the second mating portion 202 is a first slider, and the first mating portion 102 is located to the left of the second mating portion 202. The second mating portion 202 has a first sliding groove 2021 with an opening facing left. A portion of the first mating portion 102 is slidably disposed in the first sliding groove 2021 along the left-right direction through the opening of the second mating portion 202. Of course, in other embodiments, the first mating portion may be a first slider, the second mating portion may be a first sliding plate, and the first mating portion may be provided with a first sliding groove with an opening facing right.

[0086] Thus, the first slide slides relative to the first slide groove 2021 along the arrangement direction of the first support body 101 and the second support body 201, thereby achieving the rotation of the first support member 1 relative to the second support member 2. The first and second mating portions 102, 202 have simple structures, which helps to simplify the structure of the support assembly 100 and facilitates the assembly of the support assembly 100.

[0087] Optionally, the first slide groove 2021 is a through groove. In other words, the first slide groove 2021 is a through groove that passes through the first slider along the length direction of the second support body 201. Figures 1 to 4 As shown, the first sliding groove 2021 passes through the second matching portion 202 along the front-to-back direction.

[0088] Optionally, the first sliding plate is an arc-shaped sliding plate, and the first sliding plate cooperates with the first sliding groove 2021.

[0089] For example, Figures 1 to 4 As shown, the first sliding plate is an arc-shaped sliding plate, and the sidewalls of the first sliding groove 2021 are arc-shaped. The first sliding plate has a first upper surface and a first lower surface that are opposite to each other in the vertical direction, and the first sliding groove 2021 has a first upper groove sidewall and a first lower groove sidewall that are opposite to each other in the vertical direction. The first upper surface is in contact with the first upper groove sidewall and can slide relative to the first upper groove sidewall in the left-right direction, and the first lower surface is in contact with the first lower groove sidewall and can slide relative to the first lower groove sidewall in the left-right direction.

[0090] Thus, on the one hand, the first slide groove 2021 cooperates with the first slide plate to guide the sliding of the first slide plate, which is beneficial to improving the reliability of the movement between the first support member 1 and the second support member 2, thereby improving the reliability of the support assembly 100, and further improving the reliability of the foldable display screen having the support assembly 100, as well as the reliability of the terminal device having the foldable display screen. On the other hand, the first slide groove 2021 cooperates with the first slide plate, and the sidewalls of the first slide groove 2021 can also limit the first slide plate in the vertical direction, preventing the first slide plate from falling out of the first slide groove 2021 in the vertical direction, thereby facilitating the assembly of the support assembly 100.

[0091] Optionally, the second support member 2 includes a second support body 201 and a third mating portion 203 provided on the second support body 201. The third support member 3 includes a third support body 301 and a fourth mating portion 302 provided on the third support body 301. The fourth mating portion 302 is rotatably provided on the third mating portion 203, so that the third support member 3 is rotatably provided on the second support member 2.

[0092] For example, Figures 1 to 4 As shown, the third matching portion 203 is provided on the upper surface of the second supporting body 201, and the fourth matching portion 302 is provided on the upper surface of the third supporting body 301. The display panel is provided on the lower side of the second supporting body 201 and the third supporting body 301, so that the lower surface of the second supporting body 201 and the lower surface of the third supporting body 301 support corresponding parts of the display panel (the parts corresponding to the second supporting body 201 and the parts corresponding to the third supporting body 301).

[0093] Thus, when the foldable display needs to be bent, folded, or unfolded, the third mating portion 203 is rotated relative to the fourth mating portion 402 to achieve rotation of the second support member 2 relative to the third support member 3. This not only facilitates the rotation of the second support member 2 relative to the third support member 3, but also helps simplify the structures of the second support member 2 and the third support member 3. This helps further reduce the volume and weight of the support assembly 100, further reducing the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device equipped with the foldable display.

[0094] Optionally, the third matching portion 203 overhangs an edge of the second supporting body 201 in a direction toward the third supporting body 301 . The fourth matching portion 302 overhangs an edge of the third supporting body 301 in a direction toward the second supporting body 201 .

[0095] For example, Figures 1 to 5 As shown, the third matching portion 203 overhangs rightward from the right edge of the second support body 201 , and the fourth matching portion 302 overhangs leftward from the left edge of the third support body 301 .

[0096] Therefore, the distance between the third matching portion 203 and the fourth matching portion 302 is relatively close, and there is an overlapping portion between them, which facilitates the matching between the third matching portion 203 and the fourth matching portion 302, thereby helping to simplify the structure of the support assembly 100 and facilitate the assembly of the support assembly 100.

[0097] Optionally, one of the third mating portion 203 and the fourth mating portion 302 is a second slider, and the other of the third mating portion 203 and the fourth mating portion 302 is a second slide. The second slider has a second slide groove 3021 that opens toward the second slide. A portion of the second slide is slidably disposed within the second slide groove 3021 along the arrangement direction of the second support body 201 and the third support body 301 through the opening of the second slide groove 3021.

[0098] For example, Figure 2 As shown, the third mating portion 203 is a second sliding plate, the fourth mating portion 302 is a second slider, and the third mating portion 203 is located to the left of the fourth mating portion 302. The fourth mating portion 302 has a second sliding groove 3021 with an opening facing left. A portion of the third mating portion 203 is slidably disposed in the second sliding groove 3021 along the left-right direction through the opening of the fourth mating portion 302. Of course, in other embodiments, the third mating portion may be a second slider, the fourth mating portion may be a second sliding plate, and the third mating portion may be provided with a second sliding groove with an opening facing right.

[0099] Thus, the second slide plate slides relative to the second slide groove 3021 along the arrangement direction of the second support body 201 and the third support body 301, thereby achieving rotation of the second support member 2 relative to the third support member 3. The third mating portion 203 and the fourth mating portion 302 have a simple structure, which helps to simplify the structure of the support assembly 100 and facilitates assembly of the support assembly 100.

[0100] Optionally, the second chute 3021 is a through groove. In other words, the second chute 3021 is a through groove that passes through the second slider along the length direction of the third support body 301. Figures 1 to 4 As shown, the second sliding groove 3021 passes through the fourth matching portion 302 along the front-to-back direction.

[0101] Optionally, the second sliding piece is an arc-shaped sliding piece, and the second sliding piece cooperates with the second sliding groove 3021 .

[0102] For example, Figures 1 to 4As shown, the second sliding plate is an arc-shaped sliding plate, and the groove sidewalls of the second sliding groove 3021 are arc-shaped. The second sliding plate has a second upper surface and a second lower surface that are opposed in the vertical direction, and the second sliding groove 3021 has a second upper groove sidewall and a second lower groove sidewall that are opposed in the vertical direction. The second upper surface is in contact with the second upper groove sidewall and can slide relative to the second upper groove sidewall in the left-right direction, and the second lower surface is in contact with the second lower groove sidewall and can slide relative to the second lower groove sidewall in the left-right direction.

[0103] Thus, on the one hand, the second slide groove 3021 cooperates with the second slide plate to guide the sliding of the second slide plate, which is beneficial to improving the reliability of the movement between the second support member 2 and the third support member 3, thereby improving the reliability of the support assembly 100, and further improving the reliability of the foldable display screen having the support assembly 100, and the reliability of the terminal device having the foldable display screen. On the other hand, the second slide groove 3021 cooperates with the second slide plate, and the sidewalls of the second slide groove 3021 can also limit the second slide plate in the vertical direction, preventing the second slide plate from falling out of the second slide groove 3021 in the vertical direction, thereby facilitating the assembly of the support assembly 100.

[0104] Optionally, the third support member 3 includes a fifth mating portion 303 provided on the third support body 301. The fourth support member 4 includes a fourth support body 401 and a sixth mating portion 402 provided on the fourth support body 401. The sixth mating portion 402 is rotatably provided on the fifth mating portion 303, so that the fourth support member 4 is rotatably provided on the third support member 3.

[0105] For example, Figures 1 to 4 As shown, the fifth mating portion 303 is provided on the upper surface of the third supporting body 301, and the sixth mating portion 402 is provided on the upper surface of the fourth supporting body 401. The display panel is provided on the lower sides of the third supporting body 301 and the fourth supporting body 401, so that the lower surfaces of the third supporting body 301 and the fourth supporting body 401 are used to support corresponding portions of the display panel (the portions corresponding to the third supporting body 301 and the portions corresponding to the fourth supporting body 401).

[0106] Thus, when the foldable display needs to be bent, folded, or unfolded, the fifth mating portion 303 is rotated relative to the sixth mating portion 402 to achieve rotation of the third support member 3 relative to the fourth support member 4. This not only facilitates the rotation of the third support member 3 relative to the fourth support member 4, but also helps simplify the structure of the third support member 3 and the fourth support member 4. This helps further reduce the volume and weight of the support assembly 100, further reducing the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device equipped with the foldable display.

[0107] Optionally, the fifth matching portion 303 overhangs an edge of the third supporting body 301 in a direction toward the fourth supporting body 401 . The sixth matching portion 402 overhangs an edge of the fourth supporting body 401 in a direction toward the third supporting body 301 .

[0108] For example, Figures 1 to 5 As shown, the fifth matching portion 303 overhangs to the right from the right edge of the third support body 301 , and the sixth matching portion 402 overhangs to the left from the left edge of the fourth support body 401 .

[0109] Therefore, the fifth matching portion 303 and the sixth matching portion 402 are close to each other and have overlapping parts, which facilitates the matching of the fifth matching portion 303 and the sixth matching portion 402, thereby simplifying the structure of the support component 100 and facilitating the assembly of the support component 100.

[0110] Optionally, one of the fifth mating portion 303 and the sixth mating portion 402 is a third slider, and the other of the fifth mating portion 303 and the sixth mating portion 402 is a third slide. The third slider has a third slide groove 4021 that opens toward the third slide. A portion of the third slide is slidably disposed within the third slide groove 4021 along the arrangement direction of the third support body 301 and the fourth support body 401 through the opening of the third slide groove 4021.

[0111] For example, Figure 2 As shown, the fifth mating portion 303 is a third sliding plate, the sixth mating portion 402 is a third slider, and the fifth mating portion 303 is located to the left of the sixth mating portion 402. The sixth mating portion 402 has a third sliding groove 4021 with an opening facing left. A portion of the fifth mating portion 303 is slidably disposed in the third sliding groove 4021 along the left-right direction through the opening of the sixth mating portion 402. Of course, in other embodiments, the fifth mating portion may be a third slider, the sixth mating portion may be a third sliding plate, and the fifth mating portion may be provided with a third sliding groove with an opening facing right.

[0112] Thus, the third slide slides relative to the third slide groove 4021 along the arrangement direction of the third support body 301 and the fourth support body 401, thereby achieving rotation of the third support member 3 relative to the fourth support member 4. The fifth mating portion 303 and the sixth mating portion 402 have a simple structure, which helps simplify the structure of the support assembly 100 and facilitates assembly of the support assembly 100.

[0113] Optionally, the third slide groove 4021 is a through groove. In other words, the third slide groove 4021 is a through groove that passes through the third slider along the length direction of the fourth support body 401. Figures 1 to 4 As shown, the third sliding groove 4021 passes through the sixth matching portion 402 along the front-to-back direction.

[0114] Optionally, the third sliding piece is an arc-shaped sliding piece, and the third sliding piece cooperates with the third sliding groove 4021 .

[0115] For example, Figures 1 to 4 As shown, the third sliding plate is an arc-shaped sliding plate, and the sidewalls of the third sliding groove 4021 are arc-shaped. The third sliding plate has a third upper surface and a third lower surface that are opposed in the vertical direction, and the third sliding groove 4021 has a third upper groove sidewall and a third lower groove sidewall that are opposed in the vertical direction. The third upper surface is in contact with the third upper groove sidewall and can slide relative to the third upper groove sidewall in the left-right direction. The third lower surface is in contact with the third lower groove sidewall and can slide relative to the third lower groove sidewall in the left-right direction.

[0116] Thus, on the one hand, the third slide groove 4021 cooperates with the third slide plate to guide the sliding of the third slide plate, which is beneficial to improving the reliability of the movement between the third support member 3 and the fourth support member 4, thereby improving the reliability of the support assembly 100, and further improving the reliability of the foldable display screen having the support assembly 100, as well as the reliability of the terminal device having the foldable display screen. On the other hand, the third slide groove 4021 cooperates with the third slide plate, and the sidewalls of the third slide groove 4021 can also limit the third slide plate in the vertical direction, preventing the third slide plate from falling out of the third slide groove 4021 in the vertical direction, thereby facilitating the assembly of the support assembly 100.

[0117] Of course, in other embodiments, other structures may be provided between the first support member and the second support member so that the first support member can rotate relative to the second support member. For example, a hinge may be provided between the first support member and the second support member so that the first support member can rotate relative to the second support member. Other structures may also be provided between the second support member and the third support member so that the second support member can rotate relative to the third support member. For example, a hinge may be provided between the second support member and the third support member so that the second support member can rotate relative to the third support member. Other structures may also be provided between the third support member and the fourth support member so that the third support member can rotate relative to the fourth support member. For example, a hinge may be provided between the third support member and the fourth support member so that the third support member can rotate relative to the fourth support member.

[0118] Optionally, the first support member 1 includes a first stop portion 103 provided on the first support body 101, and the third support member 3 includes a second stop portion 304 provided on the third support body 301. When the first support member 1 is in the first locked position, the first stop portion 103 and the second support member 2 are spaced apart to enable the first support member 1 to rotate relative to the second support member 2, and one of the first stop portion 103 and the second stop portion 304 can abut against the other of the first stop portion 103 and the second stop portion 304 to fix the second support member 2 relative to the third support member 3. When the first support member 1 is in the first unlocked position, the second stop portion 304 moves away from the first stop portion 103 to enable the second support member 2 to rotate relative to the third support member 3.

[0119] That one of the first stop portion 103 and the second stop portion 304 can abut against the other of the first stop portion 103 and the second stop portion 304 can be understood as follows: when the first support member 1 is located in the first locking position, if the second support member 2 rotates relative to the third support member 3, then one of the first stop portion 103 and the second stop portion 304 abuts against the other of the first stop portion 103 and the second stop portion 304 to prevent the second support member 2 from rotating relative to the third support member 3; if the second support member 2 does not rotate relative to the third support member 3, then one of the first stop portion 103 and the second stop portion 304 will not abut against the other of the first stop portion 103 and the second stop portion 304.

[0120] For example, Figures 1 to 4 As shown, the first stop portion 103 is provided on the upper surface of the first support body 101, and the second stop portion 304 is provided on the upper surface of the second support body 201. When the first support member 1 is in the first locking position, the first stop portion 103 and the second support member 2 are spaced apart in the vertical direction, preventing the first stop portion 103 from blocking the first support member 1 from rotating relative to the second support member 2. Furthermore, when the first support member 1 is in the first locking position, the second stop portion 304 can abut against the first stop portion 103 to prevent the second support member 2 from rotating relative to the third support member 3. When the first support member 1 is in the first unlocking position, the second stop portion 304 and the first stop portion 103 are staggered in the left-right direction, so that the second stop portion 304 is away from the first stop portion 103. At this time, the second support member 2 can rotate relative to the third support member 3.

[0121] When the foldable display needs to be bent and folded, and the first support member 1 is in the first locked position, one of the first stop portion 103 and the second stop portion 304 abuts against the other of the first stop portion 103 and the second stop portion 304, preventing the second support member 2 from rotating relative to the third support member 3, thereby fixing the second support member 2 and the third support member 3 relative to each other. When the foldable display needs to be bent and folded, and the first support member 1 is in the first unlocked position, the second stop portion 304 moves away from the first stop portion 103, allowing the second support member 2 to rotate relative to the third support member 3.

[0122] Thus, the first stop portion 103 and the second stop portion 304 form a stop structure between the first support member 1, the second support member 2 and the third support member 3. The stop structure has a simple structure, which is conducive to further reducing the volume and weight of the support assembly 100, and can further reduce the thickness and weight of the foldable display screen, thereby further reducing the thickness and weight of the terminal device with the foldable display screen.

[0123] Optionally, when the first support member 1 is located at the first unlocking position, the first stop portion 103 abuts against the second support body 201 , so that the second support member 2 and the first support member 1 are fixed relative to each other.

[0124] For example, when the first support member 1 is in the first unlocked position, the right edge of the first stop portion 103 abuts against the second support body 201. At this time, due to the blocking effect of the first stop portion 103, the first support member 1 cannot rotate relative to the second support member 2, so that the first support member 1 and the second support member 2 are relatively fixed. At this time, the first support member 1 and the second support member 2 can rotate as a whole relative to the third support member 3. In addition, the first support member 1 and the second support member 2 can be used to stably support the corresponding parts of the display panel (the part corresponding to the first support member 1 and the part corresponding to the second support member 2). This helps to further improve the reliability of the support assembly 100.

[0125] Optionally, the first stop portion 103 overhangs from the edge of the first support body 101 in the direction toward the third support body 301 , and the second stop portion 304 overhangs from the edge of the third support body 301 in the direction toward the first support body 101 .

[0126] For example, Figures 1 to 5 As shown, the first stop portion 103 overhangs rightward from the right edge of the first support body 101 , and the second stop portion 304 overhangs leftward from the left edge of the third support body 301 .

[0127] Therefore, the first stop portion 103 and the second stop portion 304 are close to each other, and even have overlapping parts, which facilitates the cooperation between the first stop portion 103 and the second stop portion 304, thereby simplifying the structure of the support component 100 and facilitating the assembly of the support component 100.

[0128] Optionally, one of the first stop portion 103 and the second stop portion 304 is a first stop plate, the first stop plate has a first avoidance opening 1031, and the other of the first stop portion 103 and the second stop portion 304 is a first stop block. When the first support member 1 is located in the first locking position, the first stop block can abut against the first stop plate. When the first support member 1 is located in the first unlocking position, the first stop block is located in the first avoidance opening 1031 to allow the second stop portion 304 to leave the first stop portion 103.

[0129] For example, Figure 2 As shown, the first stop portion 103 is a first stop piece, the second stop portion 304 is a first stop block, and the first stop portion 103 is located to the left of the second stop portion 304. The first stop piece has a first avoidance opening 1031. Of course, in other embodiments, the first stop portion may also be a first stop block, the second stop portion may be a first stop piece, and the first avoidance opening may be provided on the first stop piece.

[0130] Thus, when the first support member 1 is in the first locked position, the first stop block abuts against the first stop plate, thereby fixing the second support member 2 and the third support member 3 relatively. When the first support member 1 is in the first unlocked position, the first stop block is located within the first avoidance opening 1031, causing the second stop portion 304 to move away from the first stop portion 103, allowing the second support member 2 to rotate relative to the third support member 3. The first stop portion 103 and the second stop portion 304 have a simple structure, thereby simplifying the structure of the support assembly 100 and facilitating assembly of the support assembly 100.

[0131] Optionally, the second support member 2 includes a third stop portion 204 provided on the second support body 201, and the fourth support member 4 includes a fourth stop portion 403 provided on the fourth support body 401. When the second support member 2 is in the second locked position, the third stop portion 204 and the third support member 3 are spaced apart to enable the third support member 3 to rotate relative to the fourth support member 4, and one of the third stop portion 204 and the fourth stop portion 403 can abut against the other of the third stop portion 204 and the fourth stop portion 403 to fix the third support member 3 relative to the fourth support member 4. When the second support member 2 is in the second unlocked position, the fourth stop portion 403 moves away from the third stop portion 204 to enable the third support member 3 to rotate relative to the fourth support member 4.

[0132] When the foldable display needs to be bent and folded, and the second support member 2 is in the second locked position, one of the third stop portion 204 and the fourth stop portion 403 abuts against the other of the third stop portion 204 and the fourth stop portion 403, preventing the third support member 3 from rotating relative to the fourth support member 4, thereby fixing the third support member 3 and the fourth support member 4 relative to each other. When the foldable display needs to be bent and folded, and the second support member 2 is in the second unlocked position, the fourth stop portion 403 moves away from the third stop portion 204, allowing the third support member 3 to rotate relative to the fourth support member 4.

[0133] Thus, the third stop portion 204 and the fourth stop portion 403 form a stop structure between the second support member 2, the third support member 3 and the fourth support member 4. The stop structure has a simple structure, which is conducive to further reducing the volume and weight of the support assembly 100, and can further reduce the thickness and weight of the foldable display screen, thereby further reducing the thickness and weight of the terminal device with the foldable display screen.

[0134] Of course, in other embodiments, a stop structure may be provided between the second support member and the third support member, so that when the first support member is in the first locked position, the second support member and the third support member are relatively fixed, and when the first support member is in the first unlocked position, the second support member can rotate relative to the third support member. A stop structure may also be provided between the third support member and the fourth support member, so that when the second support member is in the second locked position, the third support member and the fourth support member are relatively fixed, and when the second support member is in the second unlocked position, the third support member can rotate relative to the fourth support member.

[0135] Optionally, when the second support member 2 is located at the second unlocking position, the third stop portion 204 abuts against the third support member 3 , so that the second support member 2 and the third support member 3 are relatively fixed.

[0136] For example, when the second support member 2 is in the second unlocked position, the right edge of the third stop portion 204 abuts against the third support body 301. At this point, due to the blocking action of the third stop portion 204, the second support member 2 cannot rotate relative to the third support member 3, thereby fixing the second support member 2 and the third support member 3 relative to each other. At this point, the second support member 2 and the third support member 3, as a whole, can rotate relative to the fourth support member 4. Furthermore, the second support member 2 and the third support member 3 can stably support the corresponding portions of the display panel (the portion corresponding to the second support member 2 and the portion corresponding to the third support member 3). This helps further improve the reliability of the support assembly 100.

[0137] Optionally, the third stop portion 204 overhangs from the edge of the second support body 201 in a direction toward the fourth support body 401 , and the fourth stop portion 403 overhangs from the edge of the fourth support body 401 in a direction toward the second support body 201 .

[0138] For example, Figures 1 to 5 As shown, the third stop portion 204 overhangs rightward from the right edge of the second support body 201 , and the fourth stop portion 403 overhangs leftward from the left edge of the fourth support body 401 .

[0139] Therefore, the third stop portion 204 and the fourth stop portion 403 are close to each other, and even have overlapping parts, which facilitates the cooperation between the third stop portion 204 and the fourth stop portion 403, thereby helping to simplify the structure of the support component 100 and facilitate the assembly of the support component 100.

[0140] Optionally, one of the third stop portion 204 and the fourth stop portion 403 is a second stop piece having a second avoidance opening 2041, and the other of the third stop portion 204 and the fourth stop portion 403 is a second stop block. When the second support member 2 is in the second locked position, the second stop block can abut against the second stop piece. When the second support member 2 is in the second unlocked position, the second stop block is located within the second avoidance opening 2041, allowing the fourth stop portion 403 to move away from the third stop portion 204.

[0141] For example, Figure 2 As shown, the third stop portion 204 is a second stop piece, the fourth stop portion 403 is a second stop block, and the third stop portion 204 is located to the left of the fourth stop portion 403. The second stop piece has a second avoidance opening 2041. Of course, in other embodiments, the third stop portion may also be a second stop block, the fourth stop portion may be a second stop piece, and the second stop piece may be provided with a second avoidance opening.

[0142] Thus, when the second support member 2 is in the second locked position, the second stop block abuts against the second stop plate, thereby fixing the third support member 3 and the fourth support member 4 relatively. When the second support member 2 is in the second unlocked position, the second stop block is located in the second avoidance opening 2041, causing the fourth stop portion 403 to move away from the third stop portion 204, allowing the third support member 3 to rotate relative to the fourth support member 4. The third stop portion 204 and the fourth stop portion 403 have a simple structure, thereby simplifying the structure of the support assembly 100 and facilitating assembly of the support assembly 100.

[0143] Optionally, the third engaging portion 203 is a second sliding plate, the third stopping portion 204 is a second stopping plate, and the second sliding plate forms a second stopping plate. The second sliding plate includes a coupled engaging portion 2031 and a stopping portion 2032. A portion of the engaging portion 2031 is slidably disposed within the second sliding groove 3021 along the arrangement direction of the second support body 201 and the third support body 301. The second avoidance opening 2041 is disposed on the stopping portion 2032. When the second support member 2 is in the second locked position, the second stopping block can abut against the stopping portion 2032.

[0144] For example, Figures 1 to 4 As shown, the third engaging portion 203 and the third stop portion 204 are the same component, that is, the second stop plate and the second slide plate are the same component. The second slide plate includes a engaging portion 2031 and a stop portion 2032 arranged in the front-to-back direction, with the engaging portion 2031 located behind the stop portion 2032. When the second support member 2 is in the second locked position, the second stop block can abut against the front portion of the second slide plate (stop portion 2032). When the second support member 2 is in the second unlocked position, the second stop block is located within the second avoidance opening 2041 of the stop portion 2032.

[0145] Therefore, the third matching portion 203 and the third stop portion 204 are the same component, which further simplifies the structure of the first support member 1 and the third support member 3, not only facilitating the processing and assembly of the support component 100, but also helping to further reduce the volume and weight of the support component 100, and can further reduce the thickness and weight of the foldable display, and thus can further reduce the thickness and weight of the terminal device with the foldable display.

[0146] Optionally, the first support body 101, the second support body 201, and the third support body 301 are arranged along the width direction of the first support body 101. The first matching portion 102 and the first stop portion 103 are spaced apart along the length direction of the first support body 101. The third matching portion 203 is located between the second matching portion 202 and the first stop portion 103 in the length direction of the first support body 101. In other words, the third matching portion 203 is located between the first matching portion 102 and the first stop portion 103 in the length direction of the first support body 101.

[0147] For example, Figures 1 to 5 As shown, the width direction of the first support body 101 is consistent with the left-right direction, and the length direction of the first support body 101 is consistent with the front-back direction. The first support body 101, the second support body 201, and the third support body 301 are arranged in the left-right direction. The second matching portion 202 and the first stop portion 103 are spaced apart in the front-back direction, and the third matching portion 203 is located between the second matching portion 202 and the first stop portion 103 in the front-back direction.

[0148] As a result, the structure between the second mating portion 202 (first mating portion 102), the first stop portion 103 and the third mating portion 203 (third stop portion 204) is more compact, which is conducive to further reducing the volume and weight of the support assembly 100, thereby helping to further reduce the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device with the foldable display.

[0149] Optionally, the third support body 301 and the fourth support body 401 are arranged along the width direction of the first support body 101. The sixth matching portion 402 and the first stop portion 103 are spaced apart along the length direction of the first support body 101, and the third matching portion 203 is located between the sixth matching portion 402 and the first stop portion 103 in the length direction of the first support body 101.

[0150] For example, Figures 1 to 5 As shown, the third supporting body 301 and the fourth supporting body 401 are arranged in the left-right direction. The sixth matching portion 402 and the first stop portion 103 are spaced apart in the front-to-back direction. The third matching portion 203 is located between the sixth matching portion 402 and the first stop portion 103 in the front-to-back direction.

[0151] As a result, the structure between the sixth mating portion 402 (fifth mating portion 303), the first stop portion 103 and the third mating portion 203 (third stop portion 204) is more compact, which is conducive to further reducing the volume and weight of the support assembly 100, thereby helping to further reduce the thickness and weight of the foldable display, and further reducing the thickness and weight of the terminal device with the foldable display.

[0152] Optionally, the second stopping portion 304 is provided on the fourth matching portion 302 .

[0153] For example, Figures 1 to 4 As shown, the second stop portion 304 is disposed at the left edge of the fourth matching portion 302 .

[0154] As a result, the structure of the third support member 3 is more compact, which is conducive to further reducing the volume and weight of the support assembly 100, thereby helping to further reduce the thickness and weight of the foldable display screen, and further reducing the thickness and weight of the terminal device with the foldable display screen.

[0155] Optionally, the second stopping portion 304 and the fourth matching portion 302 are integrally formed.

[0156] The second stop portion 304 and the fourth matching portion 302 are integrally formed, which facilitates the processing of the third support member 3 and thus facilitates the processing of the support assembly 100 .

[0157] Optionally, the fourth stopping portion 403 is provided on the sixth matching portion 402 .

[0158] For example, Figures 1 to 4 As shown, the fourth stopping portion 403 is disposed at the left edge of the sixth matching portion 402 .

[0159] As a result, the structure of the fourth support member 4 is more compact, which is conducive to further reducing the volume and weight of the support assembly 100, thereby helping to further reduce the thickness and weight of the foldable display screen, and further reducing the thickness and weight of the terminal device with the foldable display screen.

[0160] Optionally, the fourth stopping portion 403 and the sixth matching portion 402 are integrally formed.

[0161] The fourth stop portion 403 and the sixth matching portion 402 are integrally formed, which facilitates the processing of the fourth support member 4 and thus facilitates the processing of the support assembly 100 .

[0162] Optionally, the second stopping portion 304 protrudes from an edge of the fourth matching portion 302 along the length direction of the first supporting body 101 .

[0163] For example, Figures 1 to 4 As shown, the second stopping portion 304 overhangs rearwardly beyond the edge of the fourth matching portion 302 .

[0164] Therefore, the distance between the second stop portion 304 and the first stop portion 103 is relatively close, and there is an overlapping portion between them, which facilitates the cooperation between the second stop portion 304 and the first stop portion 103, thereby helping to simplify the structure of the support assembly 100 and facilitate the assembly of the support assembly 100.

[0165] Optionally, the fourth stopping portion 403 overhangs from an edge of the sixth matching portion 402 along the length direction of the first supporting body 101 .

[0166] For example, Figures 1 to 4 As shown, the fourth stopping portion 403 overhangs rearwardly beyond the edge of the sixth matching portion 402 .

[0167] Therefore, the fourth stop portion 403 and the third stop portion 204 are close to each other and have overlapping parts, which facilitates the cooperation between the fourth stop portion 403 and the third stop portion 204, thereby helping to simplify the structure of the support component 100 and facilitate the assembly of the support component 100.

[0168] Optionally, the first support member 1 and the third support member 3 have the same structure, and the second support member 2 and the fourth support member 4 have the same structure.

[0169] For example, the first support member 1 and the third support member 3 are first-type support members, and the second support member 2 and the fourth support member 4 are second-type support members.

[0170] The support assembly 100 is mainly composed of a first type of support member and a second type of support member, and the two types of support members are alternately arranged in sequence, thereby simplifying the structure of the support assembly 100 and facilitating the assembly of the support assembly 100.

[0171] It will be understood by those skilled in the art that the first and second support members are not only Figure 1 The left side) has a matching relationship with the support parts, and has a matching relationship with the two lower levels ( Figure 1 Therefore, the first and second support members need not only be provided with the same Figure 1 In addition to the components that cooperate with the support members located on the left side) of the first level (not shown in the figure), components that cooperate with the support members located on the two levels below it are also provided. The support members located at the first level (not shown in the figure) only need to cooperate with the support members located on the two levels below it. Therefore, the structures of the support members located at the first level are different from those of the first and second types of support members mentioned above. The support members located at the second level only need to cooperate with the support members located on the level above it and the two levels below it. Therefore, the structures of the support members located at the second level are different from those of the first and second types of support members mentioned above. The support members located at the second-to-last level only need to cooperate with the support members located on the two levels above it and the level below it. Therefore, the structures of the support members located at the second-to-last level are different from those of the first and second types of support members mentioned above. The support members located at the last level (not shown in the figure) only need to cooperate with the support members located on the two levels above it.
