As described in the background art, although the foldable display device in the prior art can be folded, the flexible display screen is stretched during the folding process, and after the flexible display screen is folded for multiple times, the flexible display screen stretched for multiple times is prone to fail and cannot display normally. The inventor has found that the reason for this problem is: when the flexible display screen is folding, because the restriction of beta structure, when the flexible display screen sets up the flexible mobile terminal in the mobile terminal outside, when opening or buckling, the length of the strutting arrangement of whole flexible display screen can lengthen, consequently can stretch the flexible display screen to lead to showing inefficacy.
Based on the above, the invention provides a screen body supporting device, which can be used in a foldable flexible display screen, wherein the screen body supporting device is arranged through a rotating shaft and a folding assembly, so that a first supporting piece and a second supporting piece rotate and relatively displace, namely, when the screen body supporting device is bent, the second supporting piece guides a screen body to bend, the first supporting piece rotates and simultaneously approaches to the rotating shaft, the total length of the screen body supporting device cannot be changed, the flexible display screen cannot be stretched in the bending process, and the display screen body is prevented from losing efficacy.
Specifically, the present invention provides a screen supporting device, including: the first supporting piece is used for supporting the non-bending part of the flexible display screen body; the second supporting piece is used for supporting the bent part of the flexible display screen body; and, a drive assembly; wherein the drive assembly comprises: a rotating shaft; the folding assembly rotates relative to the rotating shaft, is relatively fixedly connected with the first supporting piece, and is relatively connected with the second supporting piece in a sliding manner; the first supporting piece and the second supporting piece rotate and relatively displace to fold or unfold the flexible display screen body through the rotating shaft and the folding assembly.
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. It is obvious that the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Fig. 1 is a schematic structural diagram of a screen supporting device according to an embodiment of the present invention, as shown in fig. 1, including: the flexible display screen comprises a first supporting piece 1 used for supporting the non-bending part of the flexible display screen body, a second supporting piece 2 used for supporting the bending part of the flexible display screen body and a driving assembly 3, wherein the driving assembly 3, the first supporting piece 1 and the second supporting piece 2 are all arranged in a non-display area of the flexible display screen body. The driving assembly 3 includes a rotating shaft 31 and a folding assembly 32 connected to the rotating shaft 31 in a relatively rotating manner, the folding assembly 32 is fixedly connected to the first supporting member 1, the folding assembly 32 is connected to the second supporting member 2 in a relatively sliding manner, when the screen supporting device is folded, the rotating shaft 31 rotates and drives the folding assembly 32 to rotate, the rotation of the folding assembly 32 enables the first supporting member 1 and the second supporting member 2 to rotate and move relatively, that is, when the screen supporting device is folded from the unfolded position to the folded position, a distance between one end of the first supporting member 1 close to the rotating shaft 31 and one end of the second supporting member 2 far from the rotating shaft 31 gradually decreases, and when the screen supporting device is folded from the folded position to the unfolded position, a distance between one end of the first supporting member 1 close to the rotating shaft 31 and one end of the second supporting member 2 far from the rotating shaft 31 gradually increases, as shown in fig. 2. That is, when folding the screen body supporting device, the second supporting member guides the screen body to be bent and the first supporting member 1 rotates and simultaneously approaches to the rotating shaft 31, that is, the distance d2 between the end of the first supporting member 1 near the rotating shaft 31 and the rotating shaft 31 is gradually reduced, as shown in fig. 2 and fig. 3, so that the total length of the screen body supporting device cannot be changed, the flexible display screen cannot be stretched in the bending process, and the display screen body is prevented from being invalid. Similarly, when the screen supporting device is folded from the folded position to the unfolded position, the distance d2 between the end of the first supporting member 1 close to the rotating shaft 31 and the rotating shaft 31 is gradually increased, so that the total length of the screen supporting device is not changed, and the flexible display screen is not wrinkled in the bending process.

When the rotating shaft 31 rotates clockwise, the rotating shaft connecting member 3211 rotates, the rotating shaft sliding member 322 rotates under the driving of the connecting rod 324 and slides toward the direction close to the rotating shaft 31 relative to the rotating shaft connecting member 3211, and due to the sliding of the rotating shaft sliding member 322, the swinging connecting rod rotatably connected to the rotating shaft sliding member 322 through the second connecting hole B drives the swinging connecting rod 32121 fixed on the rotating shaft connecting member 3211 to rotate clockwise around the third connecting hole C, so that the bending supporting member 323 rotatably connected to the swinging connecting rod 32121 through the fourth connecting hole D slides toward the direction away from the rotating shaft 31, thereby achieving that in the folding process, the sliding direction of the rotating sliding member 322 relative to the rotating shaft connecting member 3211 is opposite to the sliding direction of the bending supporting member 323 relative to the rotating. In the embodiment of the invention, the first transmission assembly adopts a structure of a swinging connecting rod, and the sliding direction of the movable sliding part 322 relative to the rotating shaft connecting piece 3211 can be opposite to the sliding direction of the bending supporting piece 323 relative to the rotating shaft connecting piece 3211 only through one component, so that the structural complexity of the screen body supporting device is reduced.

When the spindle 31 rotates clockwise, the spindle connector 3211 rotates, and the spindle slider 322 rotates under the driving of the link 324 and slides in a direction approaching the spindle 31 relative to the spindle connector 3211. Because the rotation of the rotating shaft sliding piece 322 makes the first gear 32123 rotate counterclockwise, the first gear 32123 drives the second gear 32124 to rotate clockwise, the second gear 32124 drives the third gear 32125 to rotate counterclockwise, and the third gear 32125 drives the bending support piece 323 to slide in a direction away from the rotating shaft relative to the rotating shaft connecting piece 3211, so that in the folding process, the sliding direction of the rotating sliding piece 322 relative to the rotating shaft connecting piece 3211 is opposite to the sliding direction of the bending support piece 323 relative to the rotating shaft connecting piece 3211. In the embodiment of the present invention, the first transmission assembly adopts a gear transmission manner to realize that the sliding direction of the movable sliding member 322 with respect to the rotating shaft connecting member 3211 is opposite to the sliding direction of the bending support member 323 with respect to the rotating shaft connecting member 3211, so as to reduce the structural complexity of the screen body supporting device.
