[0029] The present disclosure provides a folding assembly, which can be unfolded or folded. When the folding assembly is unfolded, two rotating assemblies rotate in directions away from each other. The middle frame drives the first rotating rod and the slider to rotate through the connecting block. Since the hinge axes of the second rotating rod and the first rotating rod on the support are not coaxial, the first rotating rod and the second rotating rod will produce relative displacement, that is, the rotation speeds are different. Since the slider and the second rotating rod are hinged, the relative sliding speeds of the slider, the first rotating rod and the connecting block are different, which causes the lever to deflect. In this way, multiple components in the rotating assembly are linked, so that the connecting block slides in a direction close to the support, and then the support is close to the middle frame. At the same time, the floating plate rotates in a direction away from the connecting block, and the floating plate and the support jointly support the flexible screen. On the contrary, when the folding assembly is folded, the two rotating assemblies rotate in a direction close to each other. The connecting block slides in a direction away from the support, so that the support is away from the middle frame. At the same time, the floating plate rotates in a direction close to the connecting block, and a water drop-shaped accommodation space is formed between the support and the two floating plates for accommodating the flexible screen, so that the flexible screen can form a natural bending shape to avoid excessive bending of the flexible screen. Since the rotating assembly is a multi-level spatial linkage structure, the operation of the folding assembly can be more stable and less prone to jamming. In addition, the overall structure of the folding assembly is relatively simple and easy to assemble, which is conducive to the mass production of the folding assembly and helps reduce production costs.

[0043] The present disclosure provides a folding assembly, such as Figure 1 and Figure 2As shown, the folding assembly is used to support the flexible screen, and the folding assembly includes a support 1 and two rotating assemblies 2. The rotating assembly 2 includes a first rotating rod 21, a second rotating rod 22, a slider 23, a connecting block 24, a lever 25 and a floating plate 26. The floating plate 26 is used to support the flexible screen, and the connecting block 24 is connected to the middle frame. One end of the first rotating rod 21 is hinged to the support 1, and the rod body of the first rotating rod 21 is slidably connected to the connecting block 24. The two ends of the second rotating rod 22 are respectively hinged to the support 1 and the slider 23, and the slider 23 is also slidably connected to the connecting block 24, wherein the hinge axes of the first rotating rod 21 and the second rotating rod 22 and the support 1 are not coaxial. The two ends of the lever 25 are respectively limitedly connected to the first rotating rod 21 and the connecting block 24, and the rod body of the lever 25 is hinged to the slider 23. The floating plate 26 is rotatably connected to the connecting block 24. In the process of closing the folding assembly, the connecting block 24 slides in a direction away from the second rotating rod 22. During the process of unfolding the folding assembly, the connecting block 24 slides in a direction away from the second rotating rod 22 .
[0044] The two rotating components 2 are symmetrical about the axis of the support 1 .
[0045] The technical solution provided by the embodiment of the present disclosure is that the folding component can be unfolded or folded. Figure 1-Figure 3 As shown, when the folding assembly is unfolded, the two rotating assemblies 2 rotate in directions away from each other. The middle frame drives the first rotating rod 21 and the slider 23 to rotate through the connecting block 24. Since the hinge axes of the second rotating rod 22 and the first rotating rod 21 on the support 1 are not coaxial, the first rotating rod 21 and the second rotating rod 22 will produce relative displacement, that is, the rotation speeds are different. Since the slider 23 and the second rotating rod 22 are hinged, the relative sliding speeds of the slider 23, the first rotating rod 21 and the connecting block 24 are different, which causes the lever 25 to deflect. In this way, multiple components in the rotating assembly 2 are linked, so that the connecting block 24 slides in a direction close to the support 1, and then the support 1 is close to the middle frame. At the same time, the floating plate 26 rotates in a direction away from the connecting block 24, and the floating plate 26 and the support 1 jointly support the flexible screen. Correspondingly, as shown Figure 1 and Figure 4 As shown, when the folding assembly is folded, the two rotating assemblies 2 rotate in a direction approaching each other. The connecting block 24 slides in a direction away from the support 1. At the same time, the floating plate 26 rotates in a direction close to the connecting block 24, and a teardrop-shaped accommodation space is formed between the support 1 and the two floating plates 26 to accommodate the flexible screen, so that the flexible screen can form a natural bending shape to avoid excessive bending of the flexible screen. Since the rotating assembly is a multi-level spatial linkage structure, the operation of the folding assembly can be more stable and less prone to jamming. In addition, the overall structure of the folding assembly is relatively simple and easy to assemble, which is conducive to the mass production of the folding assembly and helps to reduce production costs.
[0046] In some examples, such as Figure 1 and Figure 2 As shown, the two ends of the lever 25 have a first elongated hole 251 and a second elongated hole 252. The first rotating rod 21 has a first boss 211, and the first boss 211 is located in the first elongated hole 251. The connecting block 24 has a second boss 241, and the second boss is located in the second elongated hole 252. When the lever 25 rotates, the first boss 211 slides relative to the first elongated hole 251, and the second boss 241 slides relative to the second elongated hole 252. In this way, the first rotating rod 21, the slider 23 and the lever 25 can be linked.
[0047] In some examples, such as Figure 1 and Figure 2 As shown, the connecting block 24 has a limiting groove 242, one end of the lever 25 is located in the limiting groove 242, and the limiting groove 242 is used to limit the rotation range of the lever 25. The two side walls of the limiting groove 242 form a first angle, so that the lever 25 can rotate within a certain range, and prevent the lever 25 from exceeding the rotation range and causing the first rotating rod 21, the slider 23 and the connecting block 24 to separate.
[0048] In some examples, the bottom of the limiting groove 242 is at the same height as the first rotating rod 21 . This is beneficial to the rotation of the lever 25 .
[0049] In some examples, such as Figure 1 As shown, the connecting block 24 has a first slide groove 243, and the side wall of the first slide groove 243 has a first groove 2431. The first rotating rod 21 has first protrusions 212 on both sides, and the first protrusions 212 are located in the first grooves 2431. The first grooves 2431 and the first protrusions 212 can limit the first rotating rod 21 in the first slide groove 243, so as to prevent the first rotating rod 21 and the connecting block 24 from being separated when the connecting block 24 and the first rotating rod 21 rotate.
[0050] In some examples, such as Figure 1 As shown, the connecting block 24 has a second slide groove 244, and the side wall of the second slide groove 244 has a second groove 2441. The two sides of the slider 23 have second protrusions 231, and the second protrusions 231 are located in the second grooves 2441. The second slide groove 244 and the second protrusion 231 can limit the slider 23 in the second slide groove 244, so as to prevent the first rotating rod 21 and the slider 23 from being separated when the connecting block 24 and the slider 23 rotate.
[0051] Of course, in another example, the first rotating rod 21 and the slider 23 may have limiting grooves, the connecting block 24 may have protrusions, and the protrusions on the connecting block 24 may extend into the grooves, thereby realizing relative sliding of the connecting block 24 and the first rotating rod 21 and the slider 23.
[0052] In some examples, such as Figure 1 As shown, the two ends of the connecting block 24 have arc grooves 245. The two ends of the floating plate 26 have arc protrusions 261, which are located in the arc grooves 245 and are rotatably connected to the arc grooves 245. The floating plate 26 can float within a certain angle to meet the requirements of avoiding the space required for the screen after folding and effectively supporting it when flattening.
[0053] In some examples, such as Figure 1-Figure 4 As shown, the folding assembly further includes two synchronous gears 3. The synchronous gear 3 is rotatably connected to the support 1, and the two synchronous gears 3 are meshed. One end of the first rotating rod 21 has a gear structure 213, and the gear structure 213 is meshed with the synchronous gear 3. In this way, the two rotating assemblies 2 can rotate synchronously.
[0054] In some examples, such as Figure 1 As shown, the support 1 has a receiving groove 11 , and the synchronous gear 3 is located in the receiving groove 11 , so that the synchronous gear 3 does not occupy additional space.
[0055] An embodiment of the present disclosure also provides an electronic device, which includes the above-mentioned folding component.
[0056] The electronic device may be a foldable mobile phone or a foldable computer, etc. The connection block 24 of the foldable assembly is fixedly connected to the middle frame of the electronic device, and the floating plate 26 of the foldable assembly supports the flexible screen of the electronic device.
[0057] The technical solution provided by the embodiment of the present disclosure is that the folding assembly in the electronic device is a multi-level spatial linkage structure, so the operation of the folding assembly is more stable and less prone to jamming. Therefore, the electronic device can also be folded and closed smoothly. In addition, the folding assembly uses a lever 25 to realize the linkage of the rotating assembly, and the structure is relatively simple, which is conducive to the assembly of the electronic device.
[0058] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
