[0002] Electronic devices such as mobile phones and tablets have become indispensable technological products in people's lives, studies and entertainment. At present, foldable electronic devices using flexible displays require a mechanical folding mechanism to fold the flexible display to ensure that there are no failures during normal use of the flexible display and that the normal bending of the flexible display is not affected. The flexible display of foldable electronic devices can be easily carried after being folded, and has a larger display area after being unfolded, which makes it more and more popular among consumers.

[0003] In the related art, foldable electronic devices usually use a folding mechanism to unfold or fold the flexible display screen. However, after long-term use, the transmission accuracy of the traditional folding mechanism will drop sharply, resulting in abnormal noise during the movement of the folding mechanism, which is not conducive to improving the durability of the foldable device.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0049] Electronic devices such as mobile phones and tablet computers have become indispensable technological products in people's lives, learning and entertainment, bringing a lot of convenience and fun to people's lives. With the development of diversified functions of electronic devices, there are many types and brands of electronic devices, which makes it possible for consumers to choose from a lot of electronic devices. Simply improving the functional characteristics of electronic devices cannot meet people's requirements for electronic devices. The aesthetics of the shell structure of electronic devices has also become an important factor affecting the competitiveness of electronic products. Among electronic devices with similar functions or performance, the better the durability of the electronic device, the more attractive it is to consumers to buy.

[0050] As the application of flexible display screens becomes more and more mature, their application in electronic devices is becoming more and more extensive. Foldable electronic devices using flexible display screens can be folded in half for easy carrying; and when the flexible display screen is unfolded, it has a larger display area, and thus is becoming more and more popular among consumers.

[0051] However, in the related technology, a mechanical folding mechanism is required to fold the flexible display screen to ensure that there is no malfunction during the normal use of the flexible display screen and that the normal bending of the flexible display screen is not affected; at the same time, the folding mechanism cannot damage the flexible display screen. However, after long-term use of the traditional folding mechanism, the transmission accuracy will drop sharply, resulting in abnormal noise during the movement of the folding mechanism, which is not conducive to improving the durability of the foldable device.

[0052] Based on this, the present disclosure provides a folding mechanism that can reduce wear and tear, so that after the folding mechanism is used for a long time, the transmission accuracy can still be guaranteed without easily generating abnormal noise.

[0053] In order to better understand the folding mechanism of the present invention, an explanation is given through a foldable electronic device to which the folding mechanism is applied.

[0054] like Figures 1 to 5 The structure diagram of the foldable electronic device and the folding mechanism shown in some embodiments is shown. Figure 1 Schematic diagram of the structure of a foldable electronic device shown in one embodiment (the flexible display screen is in an unfolded state). Figure 2 Schematic diagram of the structure of a folding mechanism shown in an embodiment (the folding mechanism is in an unfolded state). Figure 3 for Figure 2 A front view schematic diagram of the folding mechanism shown. Figure 4 for Figure 3 The folding mechanism shown is a half-section schematic diagram cut along a first cutting direction. Figure 5 for Figure 3 The folding mechanism shown is a half-section schematic diagram cut along the second cutting direction.

[0055] like Figure 1As shown, in some embodiments of the present disclosure, a foldable electronic device 10 is provided, including a flexible display screen 10a and a folding mechanism 10b, wherein the flexible display screen 10a covers the folding mechanism 10b. The folding mechanism 10b can drive the flexible display screen 10a to switch between an unfolded state and a folded state. When the flexible display screen 10a is in the unfolded state, at least a part of the structure of the folding mechanism 10b can support the flexible display screen 10a.

[0056] Among them, combined with Figure 2 As shown, the folding mechanism 10b includes a base assembly 100, a support member 200, a rotating assembly 300 and a rolling assembly 400. The support member 200 is movably connected to the base assembly 100. The rotating assembly 300 includes a rotating member 310 rotatably connected to the base assembly 100, and the rotating member 310 includes a first connecting body 311 slidably connected to the support member 200. The rolling assembly 400 can be rotatably disposed on at least one of the first connecting body 311 and the support member 200, so that at least a portion of the first connecting body 311 is in rolling frictional cooperation with the support member 200.

[0057] When the foldable electronic device 10 is in use, the folding mechanism 10b can drive the flexible display screen 10a to switch between the unfolded state and the folded state through the support member 200. When the flexible display screen 10a is in the unfolded state, the folding mechanism 10b is in the supporting state, and supports the flexible display screen 10a through the support member 200 and the base assembly 100. The support member 200 can switch from the supporting state to the folded state, and make the flexible display screen 10a in the folded state. During the rotating member 310, the rotating member 310 can drive the support member 200 to rotate, and make the first connecting body 311 slide relative to the support member 200. The rolling assembly 400 can be rotatably disposed in the first connector 311 and / or the support 200, so that during the sliding process of the first connector 311 relative to the support 200, at least part of the first connector 311 is in rolling friction with the support 200 through the rolling assembly 400, thereby effectively reducing the wear during the sliding process between the first connector 311 and the support 200, which is conducive to maintaining the transmission accuracy between the first connector 311 and the support 200, and will not easily produce abnormal noise. In this way, the foldable electronic device 10 will not easily produce abnormal noise or shaking after long-term use, and has good durability.

[0058] It should be noted that when the flexible display screen 10a is in the unfolded state, the support member 200 is in the supporting state and can support the effective display screen. When the flexible display screen 10a is in the folded state, the support member 200 is in the folded state.

[0059] It should be noted that the friction member 320 clamped between two adjacent rotating members 310 includes the friction member 320 clamped between two rotating members 310 moving in the same direction, the friction member 320 clamped between two rotating members 310 moving in opposite directions, and part of the friction member 320 clamped between two rotating members 310 moving in the same direction and part of the friction member 320 clamped between two rotating members 310 moving in opposite directions.

[0060] Optionally, the support member 200 is slidably connected to at least two rotating members 310 .

[0061] like Figure 2 as well as Figure 3 As shown, in some embodiments, when the support member 200 is in the supporting state, the support member 200 and part of the base assembly 100 slide together to form a supporting surface for supporting the flexible display screen 10a. In this way, the flexible display screen 10a can be better supported by the supporting surface in the unfolded state, so as to facilitate viewing or touch by the user.

[0062] Alternatively, if Fig.11 As shown, in some embodiments, when the support member 200 is in the folded state, the support member 200 and the base assembly 100 are arranged at an acute angle to form an escape space. In this way, the flexible display screen 10a is easy to bend in the escape space, so that the flexible display screen 10a is folded smoothly and is not easily damaged.

[0063] It can be understood that when the support member 200 switches from the supporting state to the folding state, the support member 200 is slidably connected to the rotating member 310 so that the support member 200 moves away from the base assembly 100 to form an escape space.

[0064] It should be noted that there may be many specific implementations of the sliding connection between the support member 200 and the first connecting body 311 .

[0065] like Figure 2 as well as Figure 4 As shown, in some embodiments, one of the support member 200 and the first connecting body 311 is provided with a slide groove 210, and the other is provided with a slide rail 301 that slidably cooperates with the slide groove 210, so that the rolling assembly 400 can be rotatably arranged in the slide groove 210. In this way, through the cooperation of the slide groove 210 and the slide rail 301, the support member 200 and the first connecting body 311 are closely matched, which is conducive to reducing the thickness of the folding mechanism 10b.

[0066] Optionally, the support member 200 is provided with a slide groove 210, and the first connector 311 is provided with a slide rail 301 that slidably cooperates with the slide groove 210, and at least a portion of the slide rail 301 is inserted into the slide groove 210. In this way, the thickness space of the support member 200 is fully utilized to accommodate at least the slide rail 301, so that the first connector 311 is embedded in the support member 200, which can reduce the thickness of the folding mechanism 10b, and is conducive to realizing the thinness of the foldable electronic device 10.

[0067] It should be noted that the rolling assembly 400 can be arranged on any side wall of the first connector 311 and / or any side wall of the slide groove 210, and at least a partial rolling friction fit between the side wall of the first connector 311 and the side wall of the slide groove 210 can be achieved. In some embodiments, part of the rolling assembly 400 can be rotatably arranged on the side wall of the slide groove 210, and another part of the rolling assembly 400 can be rolled and frictionally matched with the slide rail 301. In this way, part of the rolling assembly 400 can be rotatably embedded in the side wall of the slide groove 210, and the rolling and friction fit between the first connector 311 and the support member 200 is achieved through the rolling and friction fit between the other part of the rolling assembly 400 and the slide rail 301.

[0068] In addition, it can be understood that the thickness of the support member 200 is usually greater than that of the first connector 311. Setting an installation groove on the support member 200 to accommodate the rolling assembly 400 has little effect on the strength of the support member 200, and can fully utilize the thickness space of the support member 200 to accommodate the rolling assembly 400, making the structure of the folding mechanism 10b more compact.

[0069] And / or, in some other embodiments, part of the rolling assembly 400 can be rotatably disposed on the slide rail 301, and another part of the rolling assembly 400 is in rolling frictional cooperation with the side wall of the slide groove 210. In this way, part of the rolling assembly 400 can be rotatably embedded in the side wall of the slide rail 301, and the other part of the rolling assembly 400 is in rolling frictional cooperation with the side wall of the slide groove 210, thereby realizing the rolling frictional cooperation between the first connector 311 and the support member 200.

[0070] Based on any of the above embodiments of the slide rail 301, Figure 4As shown, in some embodiments, the slide groove 210 includes a pressure-bearing surface and a first limiting surface 212 disposed adjacent to the pressure-bearing surface. The slide rail 301 includes a first mating surface 3001 that is slidably matched with the pressure-bearing surface and a second mating surface 3002 that is limitedly matched with the first limiting surface 212. Among them, the rolling component 400 can be rotatably disposed on at least one of the pressure-bearing surface and the first limiting surface 212. And / or, the rolling component 400 can be rotatably disposed on at least one of the first mating surface 3001 and the second mating surface 3002. In this way, the bearing surface 211 is slidably matched with the first matching surface 3001 to realize that the slide groove 210 carries the slide rail 301 to slide. Moreover, the first limiting surface 212 is limitedly matched with the second matching surface 3002 to limit the deviation of the slide rail 301, so that the slide rail 301 can slide along the length direction of the slide groove 210.

[0071] In addition, the rolling assembly 400 can be rotatably disposed on the pressure-bearing surface, the first limiting surface 212, or the bearing surface 211 and the first limiting surface 212. And / or, the rolling assembly 400 can be rotatably disposed on the first mating surface 3001, the second mating surface 3002, or the first mating surface 3001 and the second mating surface 3002, so as to easily realize the rolling frictional cooperation between the slide rail 301 and the first connector 311, and the implementation method can be flexibly selected according to actual needs.

[0072] Furthermore, if Figure 4 As shown, in some embodiments, there are two first limit surfaces 212, and the two first limit surfaces 212 are spaced apart on both sides of the pressure-bearing surface; and two second matching surfaces 3002 are spaced apart on both sides of the first matching surface 3001. In this way, through the limit matching of the two sets of first limit surfaces 212 and the first matching surface 3001, the slide rail 301 will not deviate left and right, but can slide along the length direction of the slide groove 210, so as to improve the sliding connection accuracy between the rotating member 310 and the supporting member 200, and further improve the transmission accuracy of the folding mechanism 10b.

[0073] In any of the above embodiments of the first limiting surface 212, Figure 4 As shown, in some embodiments, the slide groove 210 further includes a second limit surface 213 corresponding to the first limit surface 212, the second limit surface 213 is adjacent to the first limit surface 212, and is spaced apart from the pressure-bearing surface to form an anti-slip groove 214, and the slide rail 301 further includes a third matching surface 3003 that is slidably matched with the second limit surface 213, and the third matching surface 3003 is spaced apart from the first matching surface 3001 to form an anti-slip portion 3004 that is anti-slip matched with the anti-slip groove 214. In this way, through the anti-slip cooperation between the anti-slip portion 3004 and the anti-slip groove 214, the slide rail 301 will not be separated from the slide groove 210 in a direction away from the bearing surface 211, which is conducive to improving the reliability of the cooperation between the slide rail 301 and the slide groove 210.

[0074] It should be noted that, in the cross section perpendicular to the sliding direction of the slide rail 301, the specific shape of the anti-slip portion 3004 can be various, including but not limited to greater than or equal to 1 / 2 circle, greater than or equal to 1 / 2 ellipse, partial trapezoid, etc., which can limit the slide rail 301 from detaching in the direction away from the bearing surface 211.

[0075] Further, in some embodiments, the rolling assembly 400 can be rotatably disposed on at least one of the pressure-bearing surface, the first limiting surface 212, and the second limiting surface 213. And / or, the rolling assembly 400 can be rotatably disposed on at least one of the first mating surface 3001, the second mating surface 3002, and the third mating surface 3003. In this way, it is easy to realize the rolling friction cooperation between the slide rail 301 and the first connector 311, and the implementation method can be flexibly selected according to actual needs.

[0076] In one example, the rolling assembly 400 can be rotatably disposed in the first limiting surface 212 and the second limiting surface 213, and the slide rail 301 is sandwiched therebetween, so that the slide rail 301 is clearance-matched with the bearing surface 211. In this way, the slide rail 301 is point-to-surface matched with the slide groove 210 through the rolling assembly 400, ensuring that the wear of the slide rail 301 during the movement is small, which is conducive to ensuring the transmission accuracy of the rotating member 310 and the bearing member during long-term movement.

[0077] like Figure 5 As shown, in some embodiments, the rolling assembly 400 includes a plurality of rolling bodies 410, at least two rolling bodies 410 are arranged as a first group at intervals along the sliding direction of the first connecting body 311, and at least two rows of the first group are arranged at intervals between the first connecting body 311 and the supporting member 200. In this way, by arranging at least two rows of the first group at intervals between the first connecting body 311 and the supporting member 200, it is ensured that the first connecting body 311 has less wear on a single rolling body 410 during the movement, and the wear of the rolling body 410 is effectively prevented from affecting the transmission accuracy of the first connecting body 311 and the bearing member.

[0078] It should be noted that the rolling body 410 may have a variety of specific shapes, including at least one of the existing ellipsoidal sphere, spherical sphere, cylinder, and truncated cone.

[0079] In one example, the rolling element 410 is a spherical ball, which is easy to assemble.

[0080] In combination with any of the above embodiments of the slide slot 210, Figure 6As shown, in some embodiments, the folding mechanism 10b further includes a limit cover 500, which is fixedly connected to the support member 200 and covers the slide groove 210 to limit the slide rail 301 from being separated from the slide groove 210. In this way, the accommodating cavity is used to accommodate part of the slide rail 301, and the limit cover 500 is covered on the slide groove 210 to limit the rotating member 310 from being separated from the slide groove 210. It is also convenient to embed part of the slide rail 301 into the support member 200, reduce the thickness of the folding mechanism 10b, and facilitate the realization of a lightweight and thin foldable electronic device 10.

[0081] Furthermore, in some embodiments, part of the rolling assembly 400 can be rotatably disposed on the limiting cover 500. In this way, the rolling assembly 400 can also be disposed on the limiting cover 500, which is easy to assemble and helps to reduce assembly costs.

[0082] Based on any of the above embodiments, Figure 3 as well as Figure 8 As shown, in some embodiments, the rotating member 310 further includes a second connecting body 312 that is rotatably connected to the base assembly 100, and the second connecting body 312 is connected to the first connecting body 311 and is bent. In this way, through the cooperation between the second connecting body 312 and the first connecting body 311, the connecting rod 330 can move around the outer circumference of the first mounting rod 120, and it is easy to adjust the spacing between the supporting member 200 and the base assembly 100 during the sliding connection between the supporting member 200 and the first connecting body 311.

[0083] In addition, the first connector 311 can form a movable supporting plane on the supporting member 200 to support the flexible display screen 10 a.

[0084] Based on any of the above embodiments, Figure 7 As shown, in some embodiments, the folding mechanism 10b further includes a connecting rod assembly 600, through which the support member 200 is rotatably connected to the base assembly 100; the rotating assembly 300 further includes a connecting rod 330 rotatably connected to the connecting rod assembly 600, and the rotating member 310 is movably connected to the connecting rod 330. In this way, by providing the connecting rod assembly 600, it is easy to adjust the spacing between the support member 200 and the base assembly 100. When the support member 200 is in the folded state, the connecting rod assembly 600 is used to enlarge the support member 200 and the base assembly 100 to form an avoidance space. When the support member 200 is in the supporting state, the connecting rod assembly 600 is used to shrink the support member 200 and the base assembly 100 to easily form a tight supporting surface to support the flexible display screen 10a.

[0085] It should be noted that there are many specific implementations of the connecting rod assembly 600. For example, the connecting rod assembly 600 is a watch strap. For example, the connecting rod assembly 600 includes multiple connecting rods.

[0086] like Figure 3 as well as Figure 7 As shown, in some embodiments, the base assembly 100 includes a base body 110 and a first mounting rod 120 rotatably disposed on the base body 110, and the rotating member 310 is rotatably connected to the base body 110 through the first mounting rod 120. In this way, the rotating member 310 is rotatably connected to the base body 110 through the first mounting rod 120, so that the base body 110 and the rotating member 310 can be spaced along the length direction of the first mounting rod 120, so that the base body 110 will not interfere with the movement of the rotating member 310, reducing the avoidance space, and making the structure of the folding mechanism 10b more compact and occupying less space.

[0087] Based on the above embodiments, Figure 8 as well as Fig. 9 As shown, in some embodiments, one end of the second connecting body 312 is provided with a first matching hole 302 that is rotatably connected to the first mounting rod 120, and the first matching hole 302 is slidably matched with the first mounting rod 120. In this way, through the cooperation between the first matching hole 302 and the first mounting rod 120, it is easy to realize the second connecting body 312 to be rotatably connected relative to the base assembly 100, and can move along the axial direction of the rotation axis.

[0088] Based on the above embodiment of the connecting rod 330, Figure 7 , Fig. 9 as well as Fig.11 As shown, in some embodiments, the other end of the second connecting body 312 is provided with a second matching hole 303 rotatably connected to the connecting rod 330, and the first matching hole 302 is movably matched with the connecting rod 330. In this way, through the matching of the second matching hole 303 and the connecting rod 330, it is easy to realize the first connecting body 311 to be rotatably connected relative to the base assembly 100, and can move along the axial direction of the rotation axis.

[0089] Based on any of the above embodiments of the second connector 312, Figure 8 As shown, in some embodiments, part of the second connecting body 312 is arc-shaped. In this way, the first installation rod 120 can be avoided better, so as to facilitate the connection rod 330 to move around the outer circumference of the first installation rod 120.

[0090] It should be noted that the "second connecting body 312" can be "a part of the rotating member 310", that is, the "second connecting body 312" and the "other parts of the rotating member 310, such as the first connecting body 311" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the rotating member 310, such as the first connecting body 311", that is, the "second connecting body 312" can be manufactured independently and then combined with the "other parts of the rotating member 310, such as the first connecting body 311" into a whole.

[0091] Equivalently, "some body" or "some part" can be a part of the corresponding "component", that is, "some body" or "some part" can be integrally formed with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component", that is, "some body" or "some part" can be independently manufactured and then combined with the "other parts of the component" into a whole. The expression of the above-mentioned "some body" or "some part" in this disclosure is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of this disclosure. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of this disclosure.

[0092] like Figure 8 as well as Fig.10 As shown, in some embodiments, the rotating assembly 300 includes a friction member 320 that is frictionally matched with the rotating member 310, and at least two rotating members 310 are arranged on the first mounting rod 120 at intervals along the length direction of the first mounting rod 120, and the friction member 320 is arranged on the first mounting rod 120 and clamped between two adjacent rotating members 310. In this way, during the rotation of the member 310, the friction member 320 does not rotate with the rotating member 310, so that the friction member 320 and the rotating member 310 are frictionally matched, and then the rotation damping of the rotating member 310 can be increased, so that at least two rotating members 310 need to overcome a certain rotation damping before they can rotate. In this way, when the rotating member 310 is not driven by the rotation force, the support member 200 can be fixed on the base assembly 100 to achieve hovering. In addition, the foldable electronic device 10 can better hover in the process of switching between the unfolded state and the folded state, and the operation feel is better, so as to improve the user experience of the foldable device.

[0093] In addition, at least two rotating members 310 are used to move in the same direction to form a synchronous rotating member, and the friction member 320 is used to increase the rotation damping of two adjacent rotating members 310. Thus, the support member 200 can be driven to rotate by at least two rotating members 310 to ensure the matching strength of the two. At the same time, the rotation damping of the rotating member 310 can be increased.

[0094] It should be noted that "hovering" can be understood as when the rotating member 310 is not subjected to driving force, it can remain in a certain position, so that a certain rotational force is applied to the rotating member 310 so that the rotating member 310 can rotate. When the rotational force is canceled or reduced, the rotating member 310 can stop rotating and be fixed in a certain position.

[0095] It should be noted that "the support member 200 is connected to at least two rotating members 310" includes direct connection or indirect connection, and the support member 200 can be directly or indirectly driven to rotate by the rotating member 310. For example, the rotating member 310 is slidably connected to the support member 200. For example, the rotating member 310 is fixedly connected to the support member 200. For example, the rotating member 310 drives the support member 200 to rotate through other rotating structures.

[0096] It can be understood that the overall damping of the rotating assembly 300 can be flexibly adjusted by adjusting the number of the rotating members 310 and the friction members 320 to achieve the hovering motion of the supporting member 200 .

[0097] Optionally, the number of the rotating members 310 is more than three, and two adjacent rotating members 310 are each provided with at least one friction member 320 .

[0098] It should be noted that the same-direction movement includes coaxial connection, synchronous same-direction and the like.

[0099] like Figure 4 As shown, at least two rotating members 310 form a group, are coaxially connected and move in the same direction.

[0100] Based on any of the above embodiments of the friction member 320, Fig. 9 As shown, in some embodiments, at least two rotating members 310 are fixedly connected to the first mounting rod 120, and the friction member 320 is disposed on the first mounting rod 120. In this way, the first mounting rod 120 is conveniently used to integrate the rotating assembly 300, so that the structure of the rotating assembly 300 is more compact, and the space occupied is small, which is conducive to realizing the thinness of the foldable electronic device 10.

[0101] Based on any of the above embodiments of the friction member 320, combined with the above connecting rod 330, as Figure 7 as well as Fig.11 As shown, in some embodiments, the connecting rod 330 and the first mounting rod 120 are spaced apart along the rotation direction of the rotating member 310, and at least two rotating members 310 are respectively movably connected to the connecting rod 330, so that the at least two rotating members 310 rotate synchronously. In this way, by movably connecting at least two rotating members 310 to the connecting rod 330, it is convenient to realize the synchronous rotation of at least two rotating members 310.

[0102] Based on any of the above embodiments of the first mounting rod 120, Figure 8 as well as Fig. 9As shown, in some embodiments, the friction member 320 is provided with a first through hole 321, and the first mounting rod 120 is inserted into the first through hole 321 and is slidably connected with the friction member 320. In this way, through the sleeve cooperation between the first through hole 321 and the first mounting rod 120, it is easy to realize the movement of the friction member 320 relative to the axial direction of the first mounting rod 120.

[0103] Based on any of the above embodiments of the first mounting rod 120, Figure 8 as well as Fig. 9 In some embodiments shown, the rotating member 310 can slide along the length direction of the first mounting rod 120, and the friction member 320 is slidably connected to the first mounting rod 120 and does not rotate relative to the first mounting rod 120. The rotating assembly 300 also includes an elastic assembly 700 disposed on the base assembly 100, and the elastic assembly 700 squeezes at least one of the rotating member 310 and the friction member 320. In this way, when the rotating member 310 drives the supporting member 200 to switch between the supporting state and the folding state, since the friction member 320 does not rotate, and the friction member 320 and the rotating member 310 can be slidably connected relative to the first mounting rod 120, when the elastic assembly 700 squeezes at least one of the rotating member 310 and the friction member 320, the elastic squeezing force can be used to increase the friction between the rotating member 310 and the friction member 320, thereby increasing the rotation damping of the rotating member 310. In this way, when the rotating member 310 is not driven by the rotational force, the supporting member 200 can be fixed on the base assembly 100, thereby improving the hovering effect of the folding mechanism 10b.

[0104] That is, the elastic component 700 allows the rotating component 300 to be elastically telescopically moved along the length direction of the first mounting rod 120 , so as to increase the friction resistance between the rotating member 310 and the friction member 320 by utilizing the elastic squeezing force.

[0105] In other embodiments, the foldable electronic device 10 utilizes the rotating assembly 300 to allow the flexible display screen 10a to hover at any position between the folded state and the unfolded state.

[0106] It is understandable that the elastic component 700 cooperates with the friction component 320 to provide hovering damping for the rotating member 310, which is simple to operate and easy to adjust the rotation damping of the rotating member 310 by adjusting the elastic squeezing force of the elastic component 700 to meet the required hovering effect.

[0107] Furthermore, combined with Figure 6 or Figure 8As shown, in some embodiments, the folding mechanism 10b further includes a damping cam 800 disposed on the first mounting rod 120, the elastic component 700 abuts against the damping cam 800, and at least one rotating member 310 is damped by the damping cam 800. Thus, by providing the damping cam 800, the rotation damping of the rotating member 310 can be further increased, and the hovering motion of the rotating member 310 can be easily realized.

[0108] Optionally, combined Figure 8 In some embodiments shown, the damping cam 800 with damping cooperation rotating member 310 is a rotating member 310, the rotating member 310 is provided with a first arc groove and a first protrusion 305 arranged at intervals along the outer periphery of its rotation axis, and the damping cam 800 is provided with a second arc groove matched with the first protrusion 305 and a second protrusion 352 matched with the first arc groove. When the rotating member 310 is in the first state, the first protrusion 305 is arranged in the second arc groove, and the second protrusion 352 is arranged in the first arc groove. When the rotating member 310 is in the second state, the second protrusion 352 is against the first protrusion 305 to squeeze the elastic component 700. In this way, when the rotating member 310 is in the first state, the first protrusion 305 is arranged in the second arc groove, the second protrusion 352 is arranged in the first arc groove, and the damping cam 800 does not generate damping to the rotating member 310 or generates small damping, so that the folding mechanism 10b can be rotated to drive the flexible display screen 10a to move. At this time, the friction member 320 can be used to achieve the hovering effect of turning and stopping. When the rotating member 310 is in the second state, the flexible display screen 10a is in the unfolded state or the folded state, and the second protrusion 352 and the first protrusion 305 are against each other to squeeze the elastic component 700, thereby increasing the elastic deformation of the elastic component 700, thereby increasing the force of squeezing the friction member 320, and thereby increasing the rotation damping of the rotating member 310, so that the rotating component 300 needs to overcome a large rotation damping to be able to move. That is, the rotating component 300 needs a large driving force to rotate, so that the flexible display screen 10a can be fixed in the unfolded state or the folded state.

[0109] Based on any of the above embodiments, Figure 8 as well as Fig. 9 As shown, in some embodiments, the base assembly 100 includes a stopper 130 fixedly connected to the first mounting rod 120, and the stopper 130 and the damping cam 800 are spaced apart along the length direction of the first mounting rod 120. The elastic assembly 700 includes at least one first elastic member 710, and at least one first elastic member 710 is sandwiched between the stopper 130 and the damping cam 800. In this way, through the cooperation between the stopper 130 and the damping cam 800, it is convenient to install the first elastic member 710 on the base assembly 100.

[0110] Optionally, the first elastic member 710 is sleeved on the first mounting rod 120. In this way, the two are more closely matched, which is conducive to achieving a lighter and thinner folding mechanism 10b.

[0111] Furthermore, combined with Figure 8 In some embodiments shown, the base assembly 100 further includes a second mounting rod 140 fixedly disposed between the stopper 130 and the damping cam 800, and the elastic assembly 700 includes at least one second elastic member 720, and the at least one second elastic member 720 is sleeved on the second mounting rod 140 and clamped between the stopper 130 and the damping cam 800. In this way, the at least one second elastic member 720 is sleeved on the second mounting rod 140 and clamped between the stopper 130 and the damping cam 800, so as to make full use of the internal space of the folding mechanism 10b to increase the number of elastic members, so as to flexibly adjust the rotation damping of the rotating member 310 and meet the hovering effect.

[0112] In addition, through the cooperation of the first mounting rod 120, the second mounting rod 140, the limit member 130 and the damping cam 800, it is convenient to modularly install the elastic component 700 on the base component 100, and then install the rotating component 300, which is beneficial to improve assembly efficiency.

[0113] It should be noted that there may be multiple specific implementations of the first elastic member 710 and / or the second elastic member 720. For example, the first elastic member 710 and / or the second elastic member 720 are compression springs or disc springs. For example, the first elastic member 710 and / or the second elastic member 720 are springs. For example, the first elastic member 710 and / or the second elastic member 720 are elastic rubber tubes (silicone tubes, rubber tubes, etc.). It should be noted that the present disclosure does not specifically limit the specific types of the first elastic member 710 and / or the second elastic member 720.

[0114] In addition, the number of the first elastic member 710 and / or the second elastic member 720 is not limited too much, as long as the number of the rotating member 310 can be realized with damping rotation.

[0115] Optionally, combined Figure 8 As shown, in some embodiments, the first elastic member 710 is a compression spring and is sleeved on the first mounting rod 120. In this way, the structure of the rotating assembly 300 is more compact. In addition, the elastic force of the first elastic member 710 is convenient to directly act on the damping cam 800.

[0116] Optionally, combined Figure 8 As shown, in some embodiments, the second elastic member 720 is a compression spring and is sleeved on the second mounting rod 140. In this way, the structure of the rotating assembly 300 is more compact. In addition, the elastic force of the first elastic member 710 is convenient to directly act on the damping cam 800.

[0117] It should be noted that the rotation range of the rotating member 310 for the hovering cooperation can be flexibly designed according to actual needs, such as 150°, 160°, 165°, 170°, 173°, 175°, 178°, 180°, etc.

[0118] It can be understood that the friction member 320 , the rotating member 310 and the damping cam 800 are made of wear-resistant materials, which is beneficial to improving the service life of the foldable electronic device 10 .

[0119] It can be understood that the hovering effect of the rotating member 310 is achieved by the friction resistance generated by the friction member 320. If the friction coefficient of the friction member 320 is large, it is easy to wear, and after wear, the friction resistance generated by the friction member 320 will also become smaller, which is not conducive to providing the foldable electronic device 10 with a hovering effect for a long time. Fig.10 As shown, in some embodiments, the friction member 320 is provided with a first friction surface 323, the rotating member 310 is provided with a second friction surface 313 that is frictionally matched with the first friction surface 323, and at least one of the first friction surface 323 and the second friction surface 323 is provided with an oil storage recess (not shown). In this way, the oil storage recess is used to store lubricating oil to lubricate the friction member 320 and the rotating member 310, reduce the friction coefficient between the friction member 320 and the rotating member 310, and improve the wear resistance of the two, thereby providing the foldable electronic device 10 with a hovering effect for a long time.

[0120] Combination Figures 1 to 7 as well as Fig.11 As shown, in some embodiments, the foldable electronic device 10 further includes a housing assembly, the housing assembly includes a first housing 101 and a second housing 102, and the folding mechanism 10b is arranged in the housing assembly. The folding mechanism 10b includes two groups of support members 200 arranged at intervals on both sides of the base assembly 100 and a rotating assembly 300 corresponding to the support members 200, the two groups of support members 200 and the rotating assembly 300 move synchronously in the opposite direction relative to the base assembly 100, and one of the support members 200 is fixedly connected to the first housing 101, and the other support member 200 is fixedly connected to the second housing 102. The flexible display screen 10a covers the first housing 101, the folding mechanism 10b and the second housing 102. In this way, when the foldable electronic device 10 is used, the rotating assemblies 300 on both sides of the base assembly 100 rotate around the base assembly 100, and the support member 200 can be driven to rotate by the rotating member 310, so that the first housing 101 and the second housing 102 move synchronously in the opposite direction to realize the flexible display screen 10a switching between the unfolded state and the folded state.

[0121] Based on the above embodiments, Figure 7 as well as Fig.11As shown, in some embodiments, the rotating assembly 300 and the supporting member 200 correspond to each other as a second group, and the folding mechanism 10b further includes a synchronization assembly 900. The two second groups are arranged on both sides of the base assembly 100, and the two supporting members 200 are synchronized by the synchronization assembly 900 so that the two supporting members 200 are in a folded state or a supported state. In this way, the synchronization assembly 900 is used to facilitate the synchronous rotation of the two second groups of rotating members 310, so as to realize the synchronous movement of the two groups of rotating members 310, so as to drive the supporting member 200 to switch between the folded state and the supported state. Moreover, the spacing between the two groups of rotating members 310 can be flexibly adjusted.

[0122] It should be noted that there are many ways to implement the synchronization component 900, including but not limited to the meshing transmission of the synchronization gear 910, and also include other ways to implement synchronous rotation, such as a pulley mechanism, a sprocket mechanism, etc.

[0123] Furthermore, if Figure 3 As shown, in some embodiments, the synchronization assembly 900 includes at least one synchronization gear 910, and the rotating member 310 includes a gear body 306 meshed with at least one synchronization gear 910. In this way, the gear body 306 is directly or indirectly meshed with at least one synchronization gear 910 to achieve synchronous and reverse rotation of the two sets of rotating members 310. The structure is compact and easy to implement.

[0124] In combination with the above-mentioned embodiment of the first mounting rod 120, as Figure 8 As shown, in an exemplary embodiment, the base assembly 100 includes two first mounting rods 120 spaced apart, a group of rotating members 310 is disposed on one first mounting rod 120, and another group of rotating members 310 is disposed on another first mounting rod 120. The synchronization assembly 900 is disposed between the two first mounting rods 120. The friction member 320 is disposed on the two first mounting rods 120, and one end of the friction member 320 is clamped between one group of rotating members 310, and the other end of the friction member 320 is clamped between the other group of rotating members 310.

[0125] Furthermore, combined with Figure 8 As shown, in some embodiments, the base assembly 100 further includes a third mounting rod 150 sandwiched between the two sets of rotating assemblies 300, and the synchronous gear 910 is rotatably connected to the third mounting rod 150. In this way, the third mounting rod 150 is used to facilitate the rotatable arrangement of the synchronous gear 910 on the base assembly 100.

[0126] Combination Figure 8As shown, in one example, the friction member 320 is provided with a second through hole 322, and the third mounting rod 150 is inserted into the second through hole 322 and is slidably connected with the friction member 320. In this way, through the sleeve cooperation between the second through hole 322 and the third mounting rod 150, it is easy to realize the axial movement of the friction member 320 relative to the third mounting rod 150.

[0127] In addition, the friction member 320 is respectively connected to the two first mounting rods 120 and the third mounting rod 150. The connection is reliable, and friction cooperation with the two sets of rotating members 310 is achieved, which is conducive to reducing assembly procedures and improving the assembly efficiency of the rotating assembly 300.

[0128] In other embodiments, the friction members 320 that frictionally cooperate with one set of rotating members 310 are one set, and the friction members 320 that frictionally cooperate with another set of rotating members 310 are another set. The two sets of friction members 320 are respectively mounted on the base assembly 100.

[0129] It can be understood that the rotating component 300 combines the rotating component 300, the elastic component 700 and the synchronization component 900 into a module through the base component 100, and then assembles it with the base component 100 through the first mounting rod 120 and the third mounting rod 150 to achieve modular installation in the folding mechanism 10b, which is beneficial to improve assembly efficiency.

[0130] It should be noted that there are many ways to install the first mounting rod 120 and / or the third mounting rod 150 on the base assembly 100, including but not limited to shaft connection, screw connection, snap connection, riveting, welding, etc.

[0131] It should be noted that the "third mounting rod 150" can be one of the parts of the module of the "frame assembly 100", that is, it can be assembled into a module with the "other components of the frame assembly 100" and then assembled modularly; it can also be relatively independent of the "other components of the frame assembly 100" and can be installed separately, that is, it can form a whole with the "other components of the frame assembly 100" in this device.

[0132] It should be noted that the "connecting rod 330" can be one of the parts of the module "rotating component 300", that is, it can be assembled into a module with the "other components of the rotating component 300", and then modularly assembled; it can also be relatively independent of the "other components of the rotating component 300", and can be installed separately, that is, it can form a whole with the "other components of the rotating component 300" in this device.

[0133] Equivalently, the components included in the "assembly", "component", "mechanism" and "equipment" of the present disclosure can also be flexibly combined, that is, modular production can be carried out according to actual conditions, modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device. The division of the above components in the present disclosure is only one embodiment, for the convenience of reading, and not to limit the scope of protection of the present disclosure. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of the present disclosure.

[0134] It should be noted that the foldable electronic device 10 in any of the above embodiments includes but is not actually a foldable display device, a foldable smart phone, a foldable tablet computer, etc.

[0135] Reference Fig.12 As shown, in some embodiments, the foldable electronic device 10 may also include one or more of the following components: a processing component 11, a memory 12, a power component 13, a multimedia component 14, an audio component 15, an input / output interface 16, a sensor component 17, and a communication component 18.

[0136] The processing component generally controls the overall operation of the foldable electronic device, such as operations associated with display, phone calls, data communications, camera operations, and recording operations. The processing component may include one or more processors to execute instructions to complete all or part of the steps of the above method. In addition, the processing component may include one or more modules to facilitate interaction between the processing component and other components. For example, the processing component may include a multimedia module to facilitate interaction between the multimedia component and the processing component.

[0137] The memory is configured to store various types of data to support operations on the foldable electronic device. Examples of such data include instructions for any application or method operating on the foldable electronic device, contact data, phone book data, messages, pictures, videos, etc. The memory can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic disk or optical disk.
