The synchronizing member 4 is spiraled counterclockwise, and the second thread 51 is spiraled clockwise on the first connecting member 5 .

Through the threaded cooperation between the above-mentioned synchronizing member 4 and the first connecting member 5, the synchronous rotation of the rotating shaft component can be realized, thereby realizing the synchronous rotation of the screen covered on the rotating shaft component.

The support assembly 1 also includes: a second connecting piece 6;

The second connecting piece 6 is connected to the first supporting member 1a and the second supporting member 1b respectively;

The second connecting member 6 includes a slide groove 61 , and the end of the synchronization component 3 is slidably inserted into the slide groove 61 .

The second connecting member 6 is fixedly connected to the first supporting member 1a and the second supporting member 1b of the supporting assembly 1. For example, it can be fixed by screwing, welding or gluing.

In this way, the first connecting piece 5 of the synchronization component 3 can be ensured. There will be no deviation when rotating relative to the synchronizing member 4 .

When the rotating shaft component has multiple synchronization components 3 , or when one synchronization component 3 has multiple first connectors 5 , the second connector 6 has more internal connectors connected to the synchronization components 3 . The first connecting piece 5 corresponds to the chute.

In the embodiment of the present disclosure, one end of the first connecting member 5 connected to the first support member 1a or the second support member 1b also has a slider, and the slider constitutes the third component of the synchronization assembly 3 One end 31 and a second end 32 . Therefore, the cross section of the first end 31 and the second end 32 of the synchronization component 3 is generally T-shaped. In order to facilitate assembly, the cross section of the chute 61 is also generally T-shaped. The T-shaped chute 61 can prevent the synchronization component 3 from being installed backwards during the assembly process. In addition, this can make the synchronization component 3 The cooperation between the end and the chute is more reliable.

When the rotating shaft part is folded, the first end 31 and the second end 32 of the synchronizing assembly 3 slide into the chute 61 , and when the rotating shaft part is unfolded, the synchronizing assembly 3 The first end 31 and the second end 32 slide out of the chute 61 .

In some other embodiments, the slide block may also be a cube slide block or a cylindrical slide block, for example. Those skilled in the art will understand that when the shape of the slider changes, the shape of the chute corresponding to the slider should also change accordingly. For example, when the slider is cylindrical, the chute is generally oblong. Users can adjust the shapes of the slider and the chute according to different needs.

For example, the chute can also be a U-shaped groove or a dovetail groove.

Of course, the end of the synchronization component 3 does not need to have a slider. The end of the synchronization component 3 directly engages with the chute 61 and is slidably inserted into the chute 61. In this case, , the chute 61 may be a rectangular chute.

There are multiple synchronization components 3, and they are spaced at different positions of the support.

In some embodiments, the rotating shaft component may have a plurality of synchronizing components 3, and the plurality of synchronizing components 3 are spacedly distributed at different positions of the support to ensure synchronous rotation of the rotating shaft component.

The number of the synchronization components 3 can be determined according to the size of the rotating shaft component when fully expanded.

For example, when the screen size is large, one synchronization component 3 may not be able to achieve synchronous rotation of the screen well. Therefore, multiple synchronization components 3 may be provided to increase stability.

As another example, when the screen needs to be folded multiple times, multiple synchronization components 3 also need to be provided to achieve synchronous expansion or synchronous folding at different positions.

The groove is used to synchronously cooperate with the semi-cylindrical rotating shaft 71 of the fixed plate 7, so that The first connecting piece connecting the first supporting piece 1a and the first connecting piece connecting the second supporting piece 1b can rotate synchronously within a certain angle, thereby driving the first supporting piece 1a and the first supporting piece 1b. The second supporting member 1b rotates synchronously within a certain angle.

For example, when the angle between the first connecting member 5 and the fixing plate 7 is 180°, it means that the rotating shaft component is in a fully expanded state, that is, the screen 10 is flat to form an entire Screen. When the angle between the first connecting member 5 and the fixing plate 7 is 90°, it means that the rotating shaft component is in a fully folded state, that is, the two ends of the screen 10 are on opposite sides. , folds to form two different screens.

Those skilled in the art should understand that the groove and the rotating shaft do not have to be semicircular. As long as the rotating shaft 71 can rotate synchronously in the groove, the rotating shaft and the groove can be in any shape. .

In the embodiment of the present disclosure, the fixed plate 7 has a set of rotating shafts. In some other embodiments, when the rotating shaft component has multiple synchronizing components 3 , or one synchronizing component 3 has multiple first connectors 5 , the fixing plate 7 may have multiple sets of rotating shafts. , so as to be drivingly connected to a plurality of first connecting members 5 respectively.

The cover plate 8 can be fixed on the surface of the first connecting member 5 by, for example, threading, welding or gluing. The accommodating groove 62 is located above the chute 61 and communicates with the chute 61 to form an integral groove structure. In this way, during the folding process of the rotating shaft component, the cover 8 can slide together with the first connecting member 5 in the above-mentioned integral groove structure.

In some embodiments, the accommodating groove 62 may not be connected to the chute 61 , but may be a separate groove structure located above the chute 61 . The cover 8 is only fixedly connected to the synchronizing member 4 of the synchronizing assembly 3 and slides in the accommodating groove 62 along with the relative rotation of the first connecting member 5 .

In some embodiments, the cover plate 8 may not be connected to the synchronization component 3 . For example, the cover 8 may be made of flexible material, and may be folded together with the rotating shaft during the folding process of the rotating shaft.
