For a better understanding of the present application, embodiments of the present application are described below with reference to fig. 1 to 11.

Referring to fig. 1 to 3, an embodiment of the present application provides a support structure 1 for a display device. The support structure 1 may provide a mounting base for the flexible screen 40. Illustratively, flexible screen 40 refers to a screen that can be bent or rolled.

The support structure 1 of the embodiment of the present application includes a screen support member 20. Illustratively, the screen body support member 20 is a user-facing member when the user uses the display device comprising the support structure 1.

The screen support member 20 has a first dimensional state and a second dimensional state. The first dimension and the second dimension are different. The panel support member 20 includes a first support portion 21 and a second support portion 22 connected to each other. In the first size state, the first support portion 21 and the second support portion 22 are located on the same plane. The second support part 22 is displaceable in a first direction X perpendicular to the above-mentioned plane. The first support portions 21 are moved closer to each other to bring the panel support member 20 into the second size state. Illustratively, the number of the first support parts 21 is two or more.

The support structure 1 of the embodiment of the present application can be used to provide an installation foundation for the flexible screen body 40. After the supporting structural member 1 is assembled with the flexible screen body 40, the display device 100 with the size of the screen display area of the flexible screen body 40 being adjustable can be formed. After the flexible screen 40 is mounted on the screen support member 20, in the first size state, the first support portion 21 and the second support portion 22 are located on the same plane, so that the display area of the flexible screen 40 can be in the maximum state. In the second size state, the display area of the flexible screen 40 can be minimized. Like this, supporting structure 1 of the embodiment of this application can be used to adjust the area size of flexible screen body 40 to satisfy the user and to the different demands of screen display area size under different use scenes, promote user experience satisfaction.

In some embodiments, referring to fig. 2 and 3, the first support portion 21 and the second support portion 22 may be rotatably connected. The first support portion 21 and the second support portion 22 are connected by a rotating shaft, so that the second support portion 22 can rotate flexibly relative to the first support portion 21. The first support portion 21 and the second support portion 22 are distributed along the second direction Y. The axial direction of the rotating shaft is perpendicular to the second direction Y and the first direction X.

In some examples, referring to fig. 2, the first support portions 21 are located at both sides of the second support portion 22. The second support portion 22 is located between the two first support portions 21. The adjacent second supporting portions 22 are rotatably connected by a rotating shaft, so that one of the adjacent second supporting portions 22 can be flexibly rotated with respect to the other. For example, in the first size state, when the first supporting portion 21 and the second supporting portion 22 are coplanar, the axes of the rotating shafts may be coplanar.

In other examples, the first supporting portions 21 and the second supporting portions 22 are alternately connected and the first supporting portions 21 are distributed at the outermost ends. The adjacent first support portion 21 and the second support portion 22 are rotatably connected by a rotating shaft. For example, in the first size state, when the first supporting portion 21 and the second supporting portion 22 are coplanar, the axes of the rotating shafts may be coplanar.

In some embodiments, referring to fig. 1, the first supporting portion 21 and the second supporting portion 22 are plate bodies, so that the first supporting portion 21 and the second supporting portion 22 have a larger supporting surface, which can increase the contact area with the flexible screen body 40 and improve the supporting stability of the flexible screen body 40. When the first supporting part 21 and the second supporting part 22 are in the same plane, the surface of the first supporting part 21 and the surface of the second supporting part 22 can be spliced to form a larger supporting surface, which is beneficial to improving the flatness of the flexible screen, and meanwhile, the flexible screen body 40 is not easy to sink and deform when being pressed.

In some embodiments, the first support 21 and the second support 22 are rod bodies. The surfaces of the first supporting portion 21 and the second supporting portion 22 facing away from the supporting body 11 are flat surfaces, and are used for contacting with the flexible screen body 40 and supporting the flexible screen body 40. First supporting part 21 and second supporting part 22 adopt the form of the body of rod, are favorable to reducing the whole quality of bearing structure 1, are favorable to promoting the lightweight of bearing structure 1. Illustratively, two or more rows of the first support portions 21 or the second support portions 22 are provided at intervals in the third direction Z. The first direction X, the second direction Y and the third direction Z are vertical to each other.

It is understood that one of the first support portion 21 and the second support portion 22 is a plate body, and the other is a rod body.

In some embodiments, referring to fig. 3, in a state where the panel support member 20 assumes the second size, the second support portion 22 is located on one side of the first support portion 21 along the first direction X. When switching from the second size state to the first size state, the second support portion 22 rises in the first direction X, and drives the first support portion 21 to displace in the second direction.

In some embodiments, referring to fig. 4, the support structure 1 further comprises a drive member 30. The second support portion 22 is connected to the driving member 30. When switching from the first size state to the second size state, the driving member 30 is used to drive the second support portion 22 to descend in the first direction X, and the second support portion 22 may drive the first support portions 21 to approach each other in the second direction Y. When switching from the second size state to the first size state, the driving member 30 is used to drive the second support portion 22 to rise in the first direction X, and the second support portion 22 may drive the first support portions 21 to move away from each other in the second direction Y. The driving member 30 may control the speed at which the second support portion 22 ascends or descends, so that a predetermined thrust may be applied to the first support portion 21 by the second support portion 22. For example, the driving component 30 may control the second supporting portion 22 to ascend or descend at a constant speed, so as to reduce the possibility that the flexible screen body 40 is damaged due to impact force caused by unstable movement speed of the second supporting portion 22 to the flexible screen body 40.

In some embodiments, at least one second support portion 22 of all the second support portions 22 is provided with a driving part 30, so that the driving part 30 can drive all the interconnected second support portions 22 to ascend or descend through the at least one second support portion 22.

In some embodiments, the drive member 30 includes a transmission 31 and a driver 32. The transmission member 31 may be disposed at the second supporting portion 22. The transmission member 31 extends in the first direction X. The driver 32 drives the transmission member 31 to move in the first direction X to raise or lower the second support portion 22 in the first direction X. The transmission member 31 may be a structural member that moves integrally in the first direction X. The transmission member 31 can be detachably connected to the second supporting portion 22, so as to facilitate subsequent maintenance and replacement of the transmission member 31. The transmission member 31 is a rigid member, so that the transmission stability can be improved, and the possibility that the flexible screen body 40 is damaged due to instantaneous impact existing in the moving process of the second supporting portion 22 caused by unstable moving process of the transmission member 31 is reduced.

In some embodiments, the transmission member 31 is a rack or a screw, and the driver 32 is engaged with the transmission member 31 for transmission, or the transmission member 31 is a telescopic rod and the driver 32 is a hydraulic cylinder, an electric cylinder or an air cylinder for driving the transmission member 31, so as to achieve good transmission accuracy and good transmission smoothness, and reduce the possibility that the flexible screen 40 is damaged due to transient impact during the movement of the second support portion 22 caused by unstable movement of the transmission member 31.

In some embodiments, more than two drive members 30 are spaced apart along the third direction Z. More than two driving components 30 drive the second supporting portion 22 at the same time, which is beneficial to ensuring the stress balance of the second supporting portion 22, and further ensuring the motion stability of the second supporting portion 22 in the ascending or descending process.

In some embodiments, the number of the second support portions 22 is an odd number, and the number of the second support portions 22 is equal to or greater than three. The two first support parts 21 may be symmetrically disposed with respect to the second support part 22 located in the middle. The second supporting portions 22 located at both sides of the middle second supporting portion 22 may also be symmetrically disposed. The second support 22, which is located in the middle, is connected to the drive part 30. The manner of connecting the middle second supporting portion 22 and the driving component 30 can be beneficial to ensuring that the stress of each second supporting portion 22 and each first supporting portion 21 is balanced, the movement process is stable, and the possibility of damaging the flexible screen body 40 due to bad impact on the flexible screen body 40 is reduced.

In some embodiments, referring to fig. 5, the first support part 21 has a first rotation-restricting part 211. The second support portion 22 has a second rotation-restricting portion 221. In the first size state, the first rotation limiting portion 211 abuts against the second rotation limiting portion 221 to limit the rotation of the second supporting portion 22, so that after the second supporting portion 22 and the first supporting portion 21 are located on the same plane, the second supporting portion 22 does not continuously rise along the first direction X, and the possibility that the second supporting portion 22 rises over the first supporting portion 21 to jack up the flexible screen body 40 and cause tearing damage to the flexible screen body 40 is reduced.

Illustratively, one of the first rotation restricting portion 211 and the second rotation restricting portion 221 is a concave portion extending in the rotation direction of the second support portion 22, and the other is a convex portion inserted into the concave portion.
