The first support 1a and the second support 1b may be symmetrically arranged or asymmetrically arranged with respect to the intermediate support. For example: as shown in fig. 1 to 3, the first support 1a and the second support 1b are the outermost two supports of the support assembly 1.

By the meshing and interlocking of the first connecting piece 5 and the synchronizing assembly 4, the rotating shaft component can be synchronously unfolded or synchronously folded.

In the disclosed embodiment, one of the synchronizing assemblies 3 comprises one synchronizing member 4 and two first connecting members 5. One ends of the two first connecting pieces 5 are connected to the first supporting piece 1a and the second supporting piece 1b, respectively.

The end of the first connecting piece 5 meshed with the synchronizing piece 4 is provided with a second thread 51, and the first thread 41 is meshed with the second thread 51 for transmission.

The first thread 41 and the second thread 51 have opposite screw directions. For example, the first thread 41 is threaded clockwise on the synchronizing member 4 and the second thread 51 is threaded counterclockwise on the first connecting member 5, or the first thread 41 is threaded counterclockwise on the synchronizing member 4 and the second thread 51 is threaded clockwise on the first connecting member 5.

Through the threaded cooperation of the synchronizing piece 4 and the first connecting piece 5, the synchronous rotation of the rotating shaft component can be realized, so that the synchronous rotation of the screen covered on the rotating shaft component is realized.

It will be appreciated by those skilled in the art that the engagement portion may also be any other engagement mechanism such as a chute.

The support assembly 1 further comprises: a second connector 6;

the second connecting piece 6 is connected with the first supporting piece 1a and the second supporting piece 1b respectively;

The second connecting member 6 is fixedly connected to the first support member 1a and the second support member 1b of the support assembly 1, and may be fixed by screwing, welding, bonding, or the like, for example.

The second connecting piece 6 has a sliding groove 61 inside, the end of the synchronizing assembly 3 is engaged with the sliding groove 61, that is, one end of the first connecting piece 5 connected with the first supporting piece 1a and the second supporting piece 1b is engaged with the sliding groove 61, that is, the first end 31 of the synchronizing assembly 3 is engaged with the sliding groove 61 in the second connecting piece 6 connected with the first supporting piece 1a, and the second end 32 of the synchronizing assembly 3 is engaged with the sliding groove 61 in the second connecting piece 6 connected with the second supporting piece 1 b. The sliding track of the synchronizing assembly 3 is limited by the sliding groove 61, so that the synchronizing assembly 3 can only slide in the sliding groove 61, thus ensuring that the first connecting piece 5 of the synchronizing assembly 3 and the synchronizing piece 4 do not deviate when rotating relatively.

When the rotating shaft part has a plurality of the synchronizing assemblies 3, or when one of the synchronizing assemblies 3 has a plurality of the first connecting pieces 5, the second connecting piece 6 has a plurality of sliding grooves therein corresponding to the first connecting pieces 5.

In the embodiment of the present disclosure, the end of the first connecting piece 5 connected to the first support piece 1a or the second support piece 1b is further provided with a slider, and the slider forms a first end 31 and a second end 32 of the synchronization assembly 3. Thus, the first end 31 and the second end 32 of the synchronizing assembly 3 are generally T-shaped in cross section. For ease of assembly, the cross section of the chute 61 is also substantially T-shaped, the T-shaped chute 61 preventing the synchronisation assembly 3 from being reversed during assembly, and in addition, providing a more secure engagement of the end of the synchronisation assembly 3 with the chute.

The first end 31 and the second end 32 of the synchronizing assembly 3 slide into the slide groove 61 when the shaft member is folded and the first end 31 and the second end 32 of the synchronizing assembly 3 slide out of the slide groove 61 when the shaft member is unfolded.

In an embodiment of the present disclosure, the slider is a substantially rectangular parallelepiped slider.

In some other embodiments, the slider may also be a square slider or a cylindrical slider, for example. It will be appreciated by those skilled in the art that as the shape of the slider changes, the shape of the runner to which the slider corresponds should also change accordingly. For example, when the slider is cylindrical, the chute is generally oblong. The shape of the sliding block and the sliding groove can be adjusted by a user according to different requirements.

The chute may also be a U-shaped chute or a dovetail, for example.

Of course, the end of the synchronization module 3 may not have a slider, and the end of the synchronization module 3 may be directly engaged with the slide groove 61 and slidably inserted into the slide groove 61, and in this case, the slide groove 61 may be a rectangular slide groove.

The number of the synchronizing assemblies 3 is plural, and the synchronizing assemblies are distributed at different positions of the support at intervals.

In some embodiments, the shaft member may have a plurality of synchronizing assemblies 3, and the plurality of synchronizing assemblies 3 may be spaced apart at different positions of the support member to ensure synchronous rotation of the shaft member.

The number of the synchronizing assemblies 3 may be determined according to the size of the spindle unit when fully extended.

For example, when the screen size is large, one synchronizing assembly 3 may not well achieve synchronous rotation of the screen, and thus, a plurality of synchronizing assemblies 3 may be provided to increase stability.

Also, for example, when the screen needs to be folded a plurality of times, a plurality of synchronizing assemblies 3 are also required to achieve synchronous unfolding or synchronous folding at different positions.

The rotating shaft part includes:

The first connecting piece 5 has a semicircular groove on a surface facing away from the second engaging portion 51, and the groove is used for synchronously matching with the semi-cylindrical rotating shaft 71 of the fixing plate 7, so that the first connecting piece connected with the first supporting piece 1a and the first connecting piece connected with the second supporting piece 1b can synchronously rotate within a certain angle, and further the first supporting piece 1a and the second supporting piece 1b are driven to synchronously rotate within a certain angle.

Illustratively, when the angle between the first connecting member 5 and the fixing plate 7 is 180 °, the rotating shaft part is illustrated in a fully unfolded state, that is, the screen 10 is tiled to form a whole screen. When the angle between the first connecting piece 5 and the fixing plate 7 is 90 degrees, the rotating shaft component is in a completely folded state, that is, two ends of the screen 10 are respectively at two opposite sides, and two different screens are formed by folding.

It will be appreciated by those skilled in the art that the recess and the shaft need not be semi-circular, as long as the shaft 71 is capable of simultaneous mating rotation in the recess, and the shaft and the recess may be of any shape.

In the disclosed embodiment, the fixing plate 7 has a set of rotating shafts. In some other embodiments, when the rotating shaft part has a plurality of the synchronizing assemblies 3, or one of the synchronizing assemblies 3 has a plurality of the first connecting members 5, the fixing plate 7 may have a plurality of sets of rotating shafts to be in driving connection with the plurality of the first connecting members 5, respectively.

The spindle unit further includes:

a cover plate 8, said cover plate 8 being fixed to said synchronizing assembly 3.

The second connecting member 6 is further formed with a receiving groove 62 in a length direction in which the second connecting member 6 extends, and the receiving groove 62 is disposed in parallel to the extending direction of the second connecting member 6.

One end of the cover plate 8 is engaged with the accommodating groove 62 in the second connecting member 6. In this way, the cover plate 8 can slide in the accommodating groove 62 during the folding process of the rotating shaft component.

The cover plate 8 may be fastened to the surface of the first connecting piece 5, for example by screwing, welding or gluing. The accommodating groove 62 is located above the sliding groove 61 and is communicated with the sliding groove 61 to form an integral groove structure. In this way, the cover plate 8 can slide with the first coupling part 5 together in the above-described integral groove structure during folding of the shaft part.

In some embodiments, the accommodating groove 62 may not be in communication with the sliding groove 61, but may be a separate groove structure located above the sliding groove 61. The cover plate 8 is fixedly connected with only 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 synchronizing assembly 3. The cover plate 8 may, for example, be made of a flexible material and follow the shaft member to be folded together during the folding of the shaft member.
