Referring to fig. 2, fig. 2 is a schematic structural diagram of a spindle mechanism according to an embodiment of the present application. Wherein the spindle mechanism 10 may include a spindle assembly 11, a body portion 12, a first support plate 13, and a second support plate 14.

The rotating shaft assembly 11 is fixed on the main body 12, the first supporting plate 13 and the second supporting plate 14 are respectively arranged on two sides of the rotating shaft assembly 11, and the first supporting plate 13 and the second supporting plate 14 are rotatably connected with the main body 12 through the rotating shaft assembly 11.

When mounted in the foldable electronic device, the flexible screen may be connected to a first support plate 13 and a second support plate 14, the first support plate 13 and the second support plate 14 supporting the flexible screen, respectively.

When the flexible screen is in the expansion state, main part 12, first backup pad 13 and second backup pad 14 splice each other and are in the parallel and level state to make the flexible screen be the exhibition flat form, guarantee the planarization of flexible screen, improve the demonstration performance of flexible screen. When the flexible screen is folded, the first support plate 13 rotates around the main body part 12 relative to the second support plate 14, one end of the first support plate 13, which is far away from the second support plate 14, rotates to be connected with the second support plate 14, the main body part 12, the first support plate 13 and the second support plate 14 enclose with each other, and meanwhile, the first support plate 13 and the second support plate 14 support the flexible screen connected with the flexible screen. The first support plate 13 and the second support plate 14 are flat plate members, which enable the flexible screen to be placed flat at the portion where the first support plate 13 and the second support plate 14 are connected.

The rotary shaft assembly 11 is used to rotate as a hinge rotary shaft in the rotary shaft mechanism 10, the number of the rotary shaft assemblies 11 may be plural, and the plural rotary shaft assemblies 11 are axially arranged on the main body portion 12. With regard to the rotary shaft assembly 11 of the present application, reference is made to the following description of the embodiment.

Referring to fig. 2, fig. 3, fig. 4 and fig. 5, fig. 3 is a schematic structural view of a rotating shaft assembly in a folded state in an embodiment of a rotating shaft mechanism of the present application, fig. 4 is a schematic structural view of a rotating shaft assembly in an unfolded state in an embodiment of a rotating shaft mechanism of the present application, and fig. 5 is a schematic structural view of a back surface of the rotating shaft assembly in the embodiment of fig. 4, wherein one side shown in fig. 4 is connected with a flexible screen.

Specifically, the rotary shaft assembly 11 may include a slide rail assembly 100, a first rotary member 200, and a second rotary member 300. A containing groove 100a is arranged in the slide rail assembly 100, and a first end of the first rotating member 200 is inserted into the containing groove 100a and is rotatably connected with the slide rail assembly 100 in the containing groove 100 a; the first end of the second rotating member 300 is inserted into the receiving groove 100a and is rotatably connected to the sliding rail assembly 100. It is understood that the first rotating member 200 and the second rotating member 300 are strip-shaped structures, and one end of each of the strip-shaped first rotating member 200 and the strip-shaped second rotating member 300 is inserted into the receiving groove 100a and can rotate in the receiving groove 100 a.

When the first rotating member 200 and the second rotating member 300 rotate about the slide rail assembly 100, it is possible to switch between the states of being folded and unfolded from each other, i.e., from the states shown in fig. 3 to 4. When the first and second rotating

members

200 and 300 are folded with each other, the first and second rotating

members

200 and 300 are arranged in a stacked manner, and when the first and second rotating

members

200 and 300 are in a state of being unfolded with each other, the first and second rotating

members

200 and 300 are flush with each other.

In the related art, the rotating member in the rotating shaft mechanism slides in the sliding rail, so that the rotating member rotates around the virtual axis relative to the sliding rail, thereby forming a hinge structure in the rotating shaft mechanism. One end of the sliding rail is often required to be packaged with an anti-drop support, so that the rotating piece is prevented from being separated from the sliding rail when sliding. However, since the anti-drop bracket and the slide rail belong to different parts, the matching section difference between the anti-drop bracket and the slide rail is usually difficult to be made. When the flexible screen is unfolded, the part of the flexible screen opposite to the rotating shaft mechanism is difficult to flatten, and the flexible screen has obvious folding traces, so that the appearance is influenced.

In this embodiment, the rotating shaft assembly 11 includes a sliding rail assembly 100, a first rotating member 200 and a second rotating member 300, the first rotating member 200 and the second rotating member 300 rotate in the accommodating groove 100a of the sliding rail assembly 100, so that the groove wall of the accommodating groove 100a can limit the position of the first rotating member 200 and the second rotating member 300 in the direction of the rotating shaft, and the first rotating member 200 and the second rotating member 300 cannot fall off along the direction of the rotating shaft of the first rotating member 200 and the second rotating member 300 during the rotation process.

Therefore, the rotation shaft assembly 11 in the embodiment does not need the anti-dropping support to limit the first rotation member 200 and the second rotation member 300, so that the problem of large matching section difference between the anti-dropping support and the slide rail is avoided, the flatness of the flexible screen in the unfolding state is enhanced, elements (anti-dropping supports) between the rotation shaft assemblies 11 are reduced, and the production cost is reduced.

Referring further to fig. 6 and 7, fig. 6 is an exploded view of a spindle assembly in an embodiment of the spindle mechanism of the present application, and fig. 7 is a view from another perspective of the embodiment of fig. 6.

Specifically, the slide rail assembly may include a first stopper 110 and a second stopper 120.

The first limiting member 110 and the second limiting member 120 are fixedly connected, and the first limiting member 110 and the second limiting member 120 surround to form the accommodating groove 100a in fig. 3. The first rotating member 200 and the second rotating member 300 are interposed between the first limiting member 110 and the second limiting member 120, and the first limiting member 110 and the second limiting member 120 limit the first rotating member 200 and the second rotating member 300 in the direction of the rotation axes of the first rotating member 200 and the second rotating member 300, thereby preventing the first rotating member 200 and the second rotating member 300 from being disengaged in the direction of the rotation axes thereof.

Optionally, the first limiting member 110 and the second limiting member 120 may be fixedly connected by welding. In other embodiments, the connection can be achieved by glue connection, screw connection or snap connection.

Further, the first limiting member 110 may include a first limiting table 101 and a first connecting member 102, and the second limiting member 120 may include a second limiting table 103 and a second connecting member 104, wherein the first limiting table 101 is fixedly connected to the first connecting member 102, and the second limiting table 103 is fixedly connected to the second connecting member 104.

The first connecting member 102 is used for fixedly connecting the second connecting member 104, so as to fixedly connect the first limiting member 110 and the second limiting member 120, for example, the first connecting member 102 and the second connecting member 104 are fixedly connected by welding, glue connection, screw connection, or snap connection.

Further, the first connecting member 102 may further have a recess 113, and the second connecting member 104 may further have a protrusion 123, wherein the protrusion 123 is inserted into the recess 113 when the first connecting member 102 is fixedly connected to the second connecting member 104, so that the first connecting member 102 and the second connecting member 104 can resist a certain force from a direction perpendicular to the connecting direction, thereby further enhancing the connection between the first connecting member 102 and the second connecting member 104. Of course, the protrusion 123 may be disposed on the first connector 102, and the recess 113 may be disposed on the second connector 104, which is not limited herein.

When the first connecting member 102 and the second connecting member 104 are fixedly connected by welding, the first rotating member 200 and the second rotating member 300 need to be unfolded, the first limiting member 110 and the second limiting member 120 are disposed on two sides of the first rotating member 200 and the second rotating member 300 to be assembled into the state shown in fig. 5, the joint (one side shown in fig. 5) of the first connecting member 102 and the second connecting member 104 is welded, the first rotating member 200 and the second rotating member 300 are rotated to the state shown in fig. 3, and the joint (one side shown in fig. 3) of the first connecting member 102 and the second connecting member 104 is welded again to ensure that the first limiting member 110 and the second limiting member 120 are firmly connected.

The first and second limiting tables 101 and 103 are used for limiting the first and second

rotating members

200 and 300 and preventing the first and second

rotating members

When the first limiting part 110 is fixedly connected with the second limiting part 120, the first limiting table 101 and the second limiting table 103 are located on the same plane, so that when the flexible screen is unfolded, the part of the flexible screen laid on the rotating shaft mechanism is flat, and the visual effect is improved.

Optionally, the first limit table 102 may further have a screw hole 114, and the screw hole 114 is used for fixing the spindle assembly 11 in the main body 12 shown in fig. 2.

The first end of the first rotating member 200 is provided with a first sliding protrusion 201 and a second sliding protrusion 202 which are opposite to each other, that is, the end of the first rotating member 200 inserted into the accommodating groove 100a in fig. 3 is provided with the first sliding protrusion 201 and the second sliding protrusion 202 which are opposite to each other. When the first rotating member 200 is inserted into the receiving slot 100a, the first sliding protrusion 201 is opposite to the first sliding groove 111, the second sliding protrusion 202 is opposite to the third sliding groove 121, meanwhile, the first sliding protrusion 201 can be inserted into the first sliding groove 111 and can slide in the first sliding groove 111, and the second sliding protrusion 202 can be inserted into the third sliding groove 121 and can slide in the third sliding groove 121. The sliding of the first sliding protrusion 201 in the first sliding slot 111 and the sliding of the second sliding protrusion 202 in the third sliding slot 121 are converted into the rotation of the first rotating member 200 relative to the sliding rail assembly 100, so as to realize the rotating connection of the first rotating member 200 and the sliding rail assembly 100 through the virtual shaft.

The first end of the second rotating member 300 is provided with a third sliding protrusion 301 and a fourth sliding protrusion 302 which are opposite to each other, that is, the end of the second rotating member 300 inserted into the receiving groove 100a in fig. 3 is provided with the third sliding protrusion 301 and the fourth sliding protrusion 302 which are opposite to each other.

The sliding of the third sliding protrusion 301 in the second sliding slot 112 and the sliding of the fourth sliding protrusion 302 in the fourth sliding slot 122 are converted into the rotation of the second rotating member 300 relative to the sliding rail assembly 100, so as to realize the rotating connection of the second rotating member 300 with the sliding rail assembly 100 through the virtual shaft.

Alternatively, the first, second, third and fourth sliding

grooves

111, 112, 121 and 122 may be arc sliding grooves, such as semicircular sliding grooves, 1/2 sliding grooves, 1/3 sliding grooves, and the first, second, third and fourth sliding

protrusions

201, 202, 301 and 302 may be corresponding arc protrusions. The concrete parameters of the sliding groove and the protrusion can be adjusted by those skilled in the art according to actual requirements, and the present application is not limited to this.

Alternatively, the second end of the first rotating member 200 may be further provided with a first pin hole 203, and the second end of the second rotating member 300 may be further provided with a second pin hole 303. The second end of the first rotating member 200 is an end opposite to the first end of the first rotating member 200, and since the first end of the first rotating member 200 is rotatably connected to the slide rail assembly 100, the second end of the first rotating member 200 can rotate around the slide rail assembly 100. Similarly, the second end of the second rotating member 300 is the end opposite to the first end of the second rotating member 300, and since the first end of the second rotating member 300 is rotatably connected to the sliding rail assembly 100, the second end of the second rotating member 300 can rotate around the sliding rail assembly 100.

When the first and second

rotating members

200 and 300 rotate around the slide rail assembly 100 such that the first and second

rotating members

200 and 300 are folded with each other, the second end of the first rotating member 200 and the second end of the second rotating member 300 are close to each other, and when the first and second

rotating members

200 and 300 are unfolded with each other, the second end of the first rotating member 200 and the second end of the second rotating member 300 are away from each other. Based on this, the flexible screen may be connected to the second end of the first rotating member 200 and the second end of the second rotating member 300, respectively, so that the rotating shaft mechanism of the present application may fold and unfold the flexible screen.

The first pin holes 203 are used for the connection of the mating pins with the first support plate 13 shown in fig. 2, and the second pin holes are used for the connection of the mating pins with the second support plate 14 shown in fig. 2.

When the first sliding protrusion 201 slides in the first sliding slot 111, the first rotating member 200 can slide to a state of being folded with the second rotating member 300, and at this time, the first stop protrusion 2011 abuts against a side wall of the first sliding slot 111 to prevent the first rotating member 200 from continuing to rotate toward the second rotating member 300.

When the third sliding protrusion 301 slides in the second sliding slot 112, the second rotating member 300 can slide to a state of being folded with the first rotating member 200, and at this time, the second stop protrusion 3011 abuts against the side wall of the second sliding slot 112 to prevent the second rotating member 300 from continuing to rotate toward the first rotating member 200.

Since the first limiting table 101 and the second limiting table 103 are fixedly connected through the first connecting member 102 and the second connecting member 104, the first limiting table 101 and the second limiting table 103 can limit the first rotating member 200 and the second rotating member 300 in the rotating shaft direction.

Meanwhile, when the first rotating member 200 and the second rotating member 300 rotate to the unfolded state, the first rotating member 200, the second rotating member 300, the first limiting table 101 and the second limiting table 103 are located on the same plane (as shown in fig. 4), so that the flexible screen supported on the first rotating member 200, the second rotating member 300, the first limiting table 101 and the second limiting table 103 has good flatness, and the visual effect is improved.
