The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
As shown in fig. 1, embodiments of the present application provide a folding assembly, including: a support layer 300, a first resilient support structure 100 and a second resilient support structure 200, the first resilient support structure 100 and the second resilient support structure 200 being located on the same side of the support layer 300.
Specifically, the support layer 300 is used for supporting the flexible display panel, and the support layer 300 includes a first supporting portion 310, a bending portion 330, and a second supporting portion 320, which are connected in sequence, where the bending portion 330 corresponds to a folding portion of the flexible display panel. As shown in fig. 1, when the support layer 300 is in the fully unfolded state, the bent portion 330 is in a flattened state, and the first bearing portion 310, the bent portion 330 and the second bearing portion 320 are in the same plane. As shown in fig. 2, when the support layer 300 is in an intermediate state of being unfolded or folded, the bending portion 330 is bent to a certain angle, so that the first carrying portion 310 and the second carrying portion 320 form an included angle. As shown in fig. 3, when the support layer 300 is in the completely folded state, the bent portion 330 is in the bent state, and the first bearing portion 310 and the second bearing portion 320 are located at two sides of the bent portion 330 and are oppositely arranged.
Further, with continued reference to fig. 1 and 2, the first flexible supporting structure 100 is disposed on one side of the first supporting portion 310, and the second flexible supporting structure 200 is disposed on one side of the second supporting portion 320. When the support layer 300 is in a fully unfolded state, the first elastic support structure 100 abuts against the second elastic support structure 200 and is elastically deformed, at this time, the deformed first elastic support structure 100 generates a reaction force on the first bearing portion 310, and simultaneously, the second elastic support structure 200 also generates a reaction force on the second bearing portion 320, so that the bending portion 330 is under tension toward the first bearing portion 310 and toward the second bearing portion 320.
In this embodiment, the first elastic support structure 100 and the second elastic support structure 200 are disposed on a side of the support layer 300 away from the flexible display panel, the first elastic support structure 100 and the second elastic support structure 200 abut against each other and elastically deform when the support layer 300 is in a fully unfolded state, so that the bending portion 330 of the support layer 300 is under tension towards the first bearing portion 310 and the second bearing portion 320, and thus, the folding portion of the flexible display panel borne on the support layer 300 is under outward tension, thereby improving the crease problem of the folding portion of the flexible display panel, further improving the aesthetic property of the flexible display panel, and the design can prolong the service life of the flexible display panel.
Optionally, in order to improve the bending performance of the support layer 300, the bending part 330 of the support layer 300 may adopt a hollow design, for example: the bending part 330 of the support layer 300 is provided with a plurality of hollow holes arranged at intervals.
Alternatively, the supporting layer 300 may be made of an elastic material that is not easily deformed by stretching, such as an elastic metal sheet, so that the supporting layer 300 can always maintain a smooth surface during the deformation process, thereby further reducing the possibility of damage to the flexible display panel. The elastic metal sheet includes, but is not limited to, a thin steel sheet.
In some embodiments, as shown in fig. 1 to 3, the first elastic supporting structure 100 includes a first fixed portion 110, a first movable portion 120, and a first elastic connecting member 130, one end of the first elastic connecting member 130 is connected to the first fixed portion 110, and the other end of the first elastic connecting member 130 is connected to the first movable portion 120, so that the first movable portion 120 and the first fixed portion 110 are elastically connected by the first elastic connecting member 130.
As shown in fig. 1 to 3, the second elastic supporting structure 200 includes a second fixed portion 210, a second movable portion 220 and a second elastic connecting member 230, one end of the second elastic connecting member 230 is connected to the second fixed portion 210, and the other end of the second elastic connecting member 230 is connected to the second movable portion 220, so that the second movable portion 220 and the second fixed portion 210 are elastically connected by the second elastic connecting member 230.
Further, the first elastic supporting structure 100 is fixedly connected to the first carrying portion 310, and the second elastic supporting structure 200 is fixedly connected to the second carrying portion 320, specifically, the first fixing portion 110 included in the first elastic supporting structure 100 is fixedly connected to the first carrying portion 310, the second fixing portion 210 included in the second elastic supporting structure 200 is fixedly connected to the second carrying portion 320, the first movable portion 120 is located on one side of the first fixing portion 110 close to the second fixing portion 210, and the second movable portion 220 is located on one side of the second fixing portion 210 close to the first fixing portion 110.
When the support layer 300 is in the fully expanded state, the first movable portion 120 abuts against the second movable portion 220, specifically, one end of the first movable portion 120 away from the first fixed portion 110 abuts against one end of the second movable portion 220 away from the second fixed portion 210, so that the first elastic connecting member 130 and the second elastic connecting member 230 are both in the compressed state.
Optionally, the first elastic connecting member 130 and the second elastic connecting member 230 are both springs, and the specific number and arrangement of the springs may be selectively set according to actual needs.
In this embodiment, since the first movable portion 120 abuts against the second movable portion 220, when the first elastic connecting member 130 is in a compressed state, the first elastic connecting member 130 applies a reaction force to the first fixed portion 110, and when the second elastic connecting member 230 is in a compressed state, the second elastic connecting member 230 applies a reaction force to the second fixed portion 210, and since the first fixed portion 110 and the second fixed portion 210 are fixedly connected to the first bearing portion 310 and the second bearing portion 320, respectively, a tension force far away from the bending portion 330 is applied to the first bearing portion 310 and the second bearing portion 320, so as to alleviate a crease of a folding portion of the flexible display panel corresponding to the bending portion 330.
Alternatively, as shown in fig. 4 and 5, the first fixed part 110 is a hollow structure provided with a first opening 110b, and the first opening 110b faces the first movable part 120; one end of the first movable portion 120 extends from the first opening 110b to the inside of the first fixed portion 110, and is slidably connected to the first fixed portion 110, which is equivalent to the first fixed portion 110 being sleeved on the outside of one end of the first movable portion 120, and providing a certain sliding guide for the first movable portion 120.
The first elastic connecting member 130 is located inside the first fixing portion 110, one end of the first elastic connecting member 130 is connected to the closed end 110a of the first fixing portion, and the other end of the first elastic connecting member 130 is connected to one end of the first movable portion 120 located inside the first fixing portion 110. The sliding direction of the first movable portion 120 and the first fixed portion 110 is parallel to the extending direction of the first elastic connecting member 130.
Alternatively, in order to reduce the weight of the folding assembly while taking into account the supporting effect of the first elastic support structure 100 on the support layer 300, the first fixing portion 110 is a flat box-like structure including a first opening 110b and a first side opposite to the first opening 110b, and a second side and a third side arranged opposite to each other. In addition, the first movable portion 120 correspondingly connected to the first fixed portion 110 may have a flat solid or hollow box-like structure.
Alternatively, as shown in fig. 6 and 7, the second fixed part 210 is a hollow structure provided with a second opening 210b, and the second opening 210b faces the second movable part 220; one end of the second movable portion 220 extends from the second opening 210b to the inside of the second fixed portion 210, and is slidably connected to the second fixed portion 210, which is equivalent to the second fixed portion 210 being sleeved on the outside of one end of the second movable portion 220, and providing a certain sliding guide for the second movable portion 220.

The sliding direction of the second movable portion 220 and the second fixed portion 210 is parallel to the extending direction of the second elastic connecting member 230.
Alternatively, in order to reduce the weight of the folding assembly while taking into consideration the supporting effect of the second elastic support structure 200 on the support layer 300, the second fixing portion 210 is a flat box-like structure including a second opening 210b and a fourth side opposite to the second opening 210b, and a fifth side and a sixth side disposed oppositely. In addition, the second movable portion 220 connected to the second fixed portion 210 may also have a flat solid or hollow box-like structure.
Alternatively, when the support layer 300 is in the fully unfolded state, the orthographic projection of the contact surface of the first movable portion 120 and the second movable portion 220 on the bent portion divides the bent portion into two portions with equal area.
