The embodiment provides a screen supporting mechanism, which is used for supporting a flexible screen module 1, so that the flexible screen module 1 can keep a good and stable form in straight, bent and other states; because it is used for supporting the flexible screen module 1, it is usually disposed below the flexible screen module 1, and some components therein are fixedly connected with the flexible screen module 1.

The screen support mechanism comprises three components, namely two support shells 2 positioned on two sides and a connecting structure 3 arranged between the two support shells 2 and connected with the support shells 2. Support fixed connection between casing 2 and the flexible screen module 1, support casing 2 and connection structure 3 and all play the supporting role to flexible screen module 1.

Wherein at least the connection structure 3 is provided bendable in the present embodiment. The bending of the connecting structure 3 is suitable for the bending of the flexible screen module, namely when the connecting structure 3 is not bent integrally, the flexible screen module 1 is also in a straight state; when the connection structure 3 is bent, the flexible screen module 1 is correspondingly bent. The bending of the flexible screen module 1 and the bending of the connecting structure 3 may be that the latter drives the former, or the bending of the former correspondingly drives the latter to bend, which is not limited in this embodiment.

The connection structure 3 is composed of a plurality of parts, and referring to fig. 3, it can be divided into two types, i.e., a first connection member 31 and a second connection member 32. One of the connecting members is arranged in the middle of the connecting structure 3, and only one of the connecting members is arranged, and the plurality of second connecting members 32 are arranged on two sides of the first connecting member 31 respectively and are connected to the supporting shells 2 on two sides in a one-to-one buckling manner. The first connecting member 31 is a symmetrical structure, and two sides thereof are respectively provided with a first sliding groove portion for accommodating the extending portions 321 on the other second connecting members 32; the second sliding groove portions 322 of the adjacent second connecting members 32 are disposed between the adjacent second connecting members 32 via the respective extending portions 321, and particularly, the second connecting members 32 disposed at both sides of the first connecting member 31 have their own extending portions 321 disposed in the first sliding groove portions of the first connecting member 31. The second connecting members 32 have the same structure, and the direction arrangement of the second connecting members 32 on the same side of the first connecting member 31 is the same with the direction arrangement of the second connecting members 32 on the same side of the first connecting member 31, and the direction arrangement of the second connecting members 32 on both sides is symmetrical or opposite.

In this embodiment, the states in which the connection structure 3 can be formed include: in the first state, the whole connecting structure 3 is in a straight state, and the flexible screen module 1 is also in a straight state; in the second state, the connection structure 3 is partially bent or entirely bent, so that the flexible screen module 1 also assumes a bent state. Referring to fig. 4 and 5, fig. 4 and 5 show the flexible screen module 1 in a bent state, wherein one state is that the first connecting member 31 is used as a boundary line, and one half of the flexible screen module is bent, and the other half of the flexible screen module is flat, and the other state is that the flexible screen module is directly bent along the first connecting member 31, so that the size of the flexible screen module 1 is minimized, and the flexible screen module is convenient to store and carry.

In some embodiments, a first engaging groove 3221 and a second engaging groove 3222 are disposed on a groove wall of the second sliding groove portion 322 of each second connecting member 32, the first engaging groove 3221 is close to the bottom of the sliding groove portion, and the second engaging groove 3222 is close to the opening of the sliding groove portion; in the first state, the extension portion 321 on each second connecting element 32 is clamped into the first clamping groove 3221 of the adjacent second connecting element 32; in the second state, the extension 321 on the second connecting element 32 inclined to the adjacent second connecting element 32 is snapped into the second snapping groove 3222 of the adjacent second connecting element 32. Referring to fig. 6 and 7, the arrangement of the slots in the second slot portion 322 is shown, the first slot 3221 is designed for stability in a straight state, and the second slot 3222 is designed for stability in a bent state. The bending mode of the flexible screen module 1 is different for the bending conditions between the second connecting pieces 32 of each part, and the closer to the bending center, the greater the bending degree is, and the greater the inclination angle between the adjacent second connecting pieces 32 is; the farther from the bending center, the smaller the degree of bending, and the smaller the inclination angle between the adjacent second connecting members 32. Therefore, the size of the second card slot 3222 is slightly larger than that of the extension portion 321, so as to ensure that the extension portion 321 can move within an allowable range in the second card slot 3222. Fig. 6 shows a snap-fit between the adjacent second connectors 32 in the first state, and fig. 7 shows a snap-fit between the adjacent second connectors 32 in the second state.

In some embodiments, a third slot and a fourth slot are disposed on a slot wall of the first slot portion of the first connecting member 31, the third slot is close to the bottom of the slot portion, and the fourth slot is close to the opening of the slot portion; in the first state, the extension 321 on the second connector 32 adjacent to the first connector 31 is clamped into the third clamping groove on the first connector 31; in the second state, the extension 321 of the second connector 32 inclined to the first connector 31 is engaged with the fourth engaging groove of the first connector 31. Similarly to the second connecting member 32, in the first sliding groove portion of the first connecting member 31, there are also provided a third engaging groove and a fourth engaging groove, respectively.

In some embodiments, the end of the extending portion 321 on each second connecting member 32 is an expanded structure, and the expanded structure of the end of the extending portion 321 is greater than or equal to the opening of the first sliding groove portion or the second sliding groove portion 322 into which the extending portion extends. The end of the extension 321 is an expanded structure, which can ensure that the second connecting member 32 cannot slide out when nested and connected, and can form a good fit with the slots in the first and second slot parts 322.

In some embodiments, the second connectors 32 on both sides of the first connector 31 are symmetrically arranged in the same number. The second connecting members 32 have the same structure, and the same number of the second connecting members 32 disposed at both ends of the first connecting member 31 can ensure the symmetrical bending performance.

In some embodiments, the relative position between the first connector 31 and the flexible screen is fixed. The relative position is fixed, which means the position of the first connecting member 31, and the position area of the side surface of the flexible screen opposite to the first connecting member 31 is unchanged, and the specific setting mode may be that the first connecting member 31 is fixedly connected with the flexible screen, or the first connecting member 31 is fixedly connected with the frame.

In some embodiments, the connection between the connection structure 3 and the support housing 2 comprises a fixed connection or a movable connection. The fixed connection is the fixed connection of the position relation between the connecting structure 3 and the supporting shell 2, for example, the connection modes such as gluing, threaded fasteners, buckles and the like; the articulated connection means that the connection between the connection structure 3 and the support housing 2 is adjustable, including parameters such as the tightness of the connection, the spacing between the connection structure 3 and the support housing 2.

In some embodiments, when the connection between the connection structure 3 and the support housing 2 is an active connection, the second connection members 32 at two ends of the connection structure 3 are cooperatively and actively connected with the support housing 2 through the sliding slots 21, and the sliding direction of the sliding slots 21 is along the connecting line direction between the second connection members 32 and the support housing 2. Referring to fig. 3, the size of the screen supporting mechanism can be changed integrally by the structure of the sliding slot 21, so that the flexible screen module 1 can be adapted to flexible screen modules 1 with various sizes, and the flexible screen module 1 can be bent at different angles in different forms.

In some embodiments, an anti-reverse-folding limiting mechanism is further arranged above the second connecting piece 32 and the first connecting piece 31.
