Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

In the description of this application, "a plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise expressly specified.

[0038] The applicant noted that existing hinge mechanisms have poor versatility and high cost. Therefore, this application provides a hinge mechanism and a folding display device. In this way, the track module and the first fixing module, as well as the track module and the second fixing module, are detachably connected. Different folding display devices can be adapted simply by disassembling and replacing the track module, improving the versatility of the hinge mechanism and reducing costs.

[0039] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 The schematic diagram illustrates the structure of the rotating shaft mechanism provided in the embodiments of this application; Figure 2 This illustration shows the structure of the first fixing module and the second fixing module in the rotating shaft mechanism provided in the embodiments of this application; Figure 3 This illustration shows a structural diagram of the connection between the support and the track module in the rotating shaft mechanism provided in an embodiment of this application; Figure 4 This illustration shows a structural diagram of the bracket in the rotating shaft mechanism provided in an embodiment of this application. An embodiment of this application provides a rotating shaft mechanism including a bracket 100, multiple track modules 130, a first fixing module 400, and a second fixing module 500.

[0040] Specifically, the bracket 100 has an internal receiving area 140, and a folding guide rail 141 is provided on the inner wall of the receiving area 140. The extension direction of the folding guide rail 141 is perpendicular to the first direction X. Multiple track modules 130 are disposed in the receiving area. The track modules 130 are provided with a first connecting portion 110 along the first axis 200 and a second connecting portion 120 along the second axis 300. The first axis 200 and the second axis 300 are parallel. The track modules 130 have guide rail grooves 131 that are perpendicular to the first axis 200 and the second axis 300. The guide rail grooves 131 cooperate with the folding guide rail 141 to allow the track modules 130 to move along the extension direction of the folding guide rail 141. The first fixing module 400 is provided with a third connecting portion 410 along the first direction X; the second fixing module 500 is provided with a fourth connecting portion 510 along the first direction X; the second fixing module 500 and the first fixing module 400 extend along the first direction X; the first direction X is parallel to the first axis 200; wherein, the first connecting portion 110 and the third connecting portion 410 are detachably connected so that the track module 130 is detachably connected to the first fixing module 400; the second connecting portion 120 and the fourth connecting portion 510 are detachably connected so that the track module 130 is detachably connected to the second fixing module 500.

[0041] Thus, the track module 130, the first fixing module 400, and the second fixing module 500 are relatively independent of each other. When the trajectory of the folding display device changes, the track module 130 and the first fixing module 400, as well as the track module 130 and the second fixing module 500, are detachably connected. Different folding display devices can be adapted simply by disassembling and replacing the track module 130, thereby improving the versatility of the hinge mechanism and reducing costs.

[0042] In this embodiment, when the rotating shaft mechanism is in the open state, since the track module 130 is connected to the first fixing module 400 and the second fixing module 500, applying a force away from the bracket 100 to the first fixing module 400 and the second fixing module 500 will cause the first connecting part 110 to move via the third connecting part 410, thereby moving one track module 130. The fourth connecting part 510 will then drive the second connecting part 120, thereby moving the other track module 130. Furthermore, since the guide rail groove 131 cooperates with the folding guide rail 141, the track module 130 can move within the receiving area 140 along the extending direction of the folding guide rail 141. Figure 1 The direction of the curved arrow indicates the folding effect of the pivot mechanism. Correspondingly, when the pivot mechanism is in the folded state, applying a force towards the bracket 100 to the first fixing module 400 and the second fixing module 500 will cause the first connecting part 110 to move via the third connecting part 410, thereby moving one track module 130. The fourth connecting part 510 will then move the second connecting part 120, thereby moving the other track module 130. Furthermore, because the guide rail groove 131 engages with the folding guide rail 141, the track module 130 can move in the opposite direction within the receiving area 140 along the extension direction of the folding guide rail 141. Figure 1 The opposite direction of the curved arrow enables the opening effect of the rotating shaft mechanism.

[0043] In some embodiments, the track module 130 further includes a bracket, and a first slide rail module and a second slide rail module disposed inside the bracket, wherein the first axis 200 is the rotation axis of the first slide rail module, and the second axis 300 is the rotation axis of the second slide rail module.

[0044] In some embodiments, along the first direction X, the first fixing module 400 has a first dimension L1, and the third connecting part 410 has a second dimension L2, satisfying that L2 ≤ L1. Thus, the dimensions of the first fixing module 400 and the third connecting part 410 can be selected according to the specific application scenario to achieve optimal installation flexibility and stability.

[0045] In some embodiments, along the first direction X, the second fixing module 500 has a third dimension L3, and the fourth connecting part 510 has a fourth dimension L4, satisfying that L4 ≤ L3. Thus, the dimensions of the second fixing module 500 and the fourth connecting part 510 can be selected according to the specific application scenario to achieve optimal installation flexibility and stability.

[0046] In some implementations, the hinge mechanism satisfies: L1 = L3 and L2 = L4. Thus, when the first dimension L1 and the second dimension L2 are equal, and the third dimension L3 and the fourth dimension L4 are equal, the synchronous movement between the hinge mechanism and the various parts of the folding display device can be further maintained, so as to achieve consistency in the position and angle of the display screen, and make the folding and unfolding process of the display screen smooth and seamless.

[0047] In some embodiments, the first connecting portion 110 and the second connecting portion 120 are recessed portions, while the third connecting portion 410 and the fourth connecting portion 510 are convex portions, and the recessed and convex portions are detachably connected. Specifically, the detachable connection of the recessed and convex portions in the embodiments of this application is more flexible and can improve the assembly efficiency and production efficiency between the first connecting portion 110 and the second connecting portion 120, as well as the third connecting portion 410 and the fourth connecting portion 510. At the same time, the detachable connection of the recessed and convex portions also has good stability and reliability, maintaining the stability of the connection during the connection of the first connecting portion 110 and the second connecting portion 120, and the third connecting portion 410 and the fourth connecting portion 510, reducing the risk of loosening or failure.

[0048] In some embodiments, the recess is a dovetail groove and the protrusion is a dovetail boss. In the embodiments of this application, the special geometry of the dovetail allows the first connecting part 110 and the second connecting part 120, as well as the third connecting part 410 and the fourth connecting part 510, to mesh tightly when connected, which can withstand a large load and provide a stable connection, reducing the risk of loosening or failure.

[0049] In some embodiments, the rotating shaft mechanism has a second direction Y, which is perpendicular to the first direction X and the first shaft 200. The rotating shaft mechanism further includes: a rotating mechanism 600, which includes a first rotating portion 610 and a second rotating portion 620 spaced apart along the second direction Y; a first fixing module 400 including a third rotating portion 420, which is detachably connected to the first rotating portion 610 so that the first fixing module 400 and the rotating mechanism 600 are detachably connected; and a second fixing module 500 including a fourth rotating portion 520, which is detachably connected to the second rotating portion 620 so that the second fixing module 500 and the rotating mechanism 600 are detachably connected.

[0050] Specifically, the rotating mechanism 600 serves both a torque and a synchronization function. The torque function provides the torque required for the folding display device during folding, ensuring the stability of the display screen when unfolded and guaranteeing a tight connection during folding. The synchronization function maintains synchronized movement between the rotating mechanism and various parts of the folding display device, ensuring consistent position and angle of the display screen and making the folding and unfolding process smooth and seamless.

[0051] In this embodiment, the specific torque action and synchronization action are achieved through the linkage between the first rotating part 610, the second rotating part 620, the third rotating part 420 and the fourth rotating part 520.

[0052] In some embodiments, along the first direction X, the first rotating part 610 is provided with a first rotating groove 611, and the third rotating part 420 is provided with a first rotating hole 421. The first rotating groove 611 and the first rotating hole 421 are detachably connected by a first bolt 700. Along the first direction X, the second rotating part 620 is provided with a second rotating groove 621, and the fourth rotating part 520 is provided with a second rotating hole 521. The second rotating groove 621 and the second rotating hole 521 are detachably connected by a second bolt 800. When the folding display device needs to be unfolded or folded, since the first rotating groove 611 and the first rotating hole 421 are detachably connected by the first bolt 700, the first rotating part 610 and the third rotating part 420 can perform relative circumferential motion within a certain range around the first direction X, thereby achieving torque and synchronization. Similarly, since the second rotating groove 621 and the second rotating hole 521 are detachably connected by the second bolt 800, the second rotating part 620 and the fourth rotating part 520 can also perform relative circumferential motion within a certain range around the first direction X, thereby achieving torque and synchronization.

[0053] In some embodiments, the first rotating groove 611 and the second rotating groove 621 are arc-shaped rotating grooves. Specifically, the arc-shaped rotating groove can reduce friction and wear between objects, thereby distributing the load during rotation or rolling, reducing friction at the contact points, better dispersing stress, and extending service life; moreover, the arc-shaped rotating groove can provide smoother and more stable motion, reduce vibration and instability, and make the motion between the first rotating part 610 and the third rotating part 420, and between the second rotating part 620 and the fourth rotating part 520, smoother and more reliable.

[0054] Compared with the prior art, the track mechanism of this application embodiment includes: a track module 130, which has a first connecting portion 110 along a first axis 200 and a second connecting portion 120 along a second axis 300; the first axis 200 and the second axis 300 are parallel; a first fixing module 400, which has a third connecting portion 410 along a first direction X; a second fixing module 500, which has a fourth connecting portion 510 along the first direction X; the second fixing module 500 and the first fixing module 400 extend along the first direction X; the first direction X is parallel to the first axis 200; wherein the first connecting portion 110 and the third connecting portion 410 are detachably connected so that the track module 130 is detachably connected to the first fixing module 400, and the second connecting portion 120 and the fourth connecting portion 510 are detachably connected so that the track module 130 is detachably connected to the second fixing module 500. Thus, the track module 130 and the first fixed module 400, as well as the track module 130 and the second fixed module 500, are detachable connections. By simply disassembling and replacing the track module 130, different folding display devices can be adapted, improving the versatility of the hinge mechanism and reducing costs.

[0055] Accordingly, this application provides a foldable display device. Please refer to [link / reference]. Figure 5 , Figure 5 This illustration shows a structural diagram of a foldable display device provided in an embodiment of this application. The foldable display device includes a folding portion 910, a middle frame 920, a display screen 930, and a hinge mechanism as described in any of the above embodiments. The folding portion 910 extends along a first direction X; the middle frame 920 is connected to both sides of the folding portion 910 along a second direction Y; the display screen 930 is connected to the middle frame 920; the hinge mechanism is disposed between the middle frame 920 and the display screen 930, and the first fixing module 400 of the hinge mechanism is connected to one middle frame 920, and the second fixing module 500 of the hinge mechanism is connected to the other middle frame 920.

[0056] In this embodiment, only a force needs to be applied to the two middle frames 920 towards the display screen 930 to make the middle frames 920 move along the movement trajectory of the rotating shaft mechanism. Figure 5 The direction of the curved arrow in the middle allows the display screen 930 to fold; correspondingly, by applying a force away from the display screen 930 to the two middle frames 920 respectively, the middle frames 920 can move in the opposite direction along the movement trajectory of the pivot mechanism, that is... Figure 5 The display screen 930 is opened by moving the arrow in the opposite direction of the arc.

[0057] It is understood that the hinge mechanism of this application should also be applicable to folding display devices with three or more middle frames 920, simply by setting the hinge mechanism between two adjacent middle frames 920.
