[0002] During the bending process of a conventional bendable device, two components in a relative motion relationship may cause scratches, thereby generating vibration and abnormal noise. Especially when the two components in a relative motion relationship are made of metal, the vibration and abnormal noise generated will be particularly obvious. Summary of the invention

[0003] In order to solve the above-mentioned problems existing in the prior art, on the first aspect, the present application provides a bendable device, which includes a first rotating member and a second rotating member that will undergo relative movement during a bending process, and the second rotating member includes a main body and a vibration damping body that are connected, and the vibration damping body forms the portion where the second rotating member contacts the first rotating member, and is used to reduce the vibration and abnormal sound generated by the second rotating member and the first rotating member during the relative movement.

[0004] In a second aspect, the present application provides a foldable device, which includes a flexible member and the above-mentioned bendable device, wherein the flexible member is disposed on the bendable device and can be folded along with the bending of the bendable device.

[0006] The present application designs the second rotating member to include a connected main body and a vibration damping body, and the vibration damping body forms the portion of the second rotating member that contacts the first rotating member. Therefore, when the second rotating member moves relative to the first rotating member, the portion of the second rotating member that rubs against the first rotating member is its vibration damping body, thereby avoiding scratching between the main body and the first rotating member during movement, which is beneficial to reducing vibration and abnormal noise that may be generated by the bendable device during the bending process.

[0037] Of course, the foldable device 10 provided in the embodiment of the present application may also be a non-electronic device. The flexible member 11 is not limited to being a flexible display screen.

[0038] See also Figure 4 and Figure 5 , Figure 4 is a schematic diagram of the structure of a bendable device in an unfolded state provided by some embodiments of the present application, Figure 5 yes Figure 4 A schematic diagram of the structure of the bendable device in the embodiment in a bent state. The bendable device 12 can be bent, so that the flexible member 11 can be folded along with the bending of the bendable device 12.

[0039] In some embodiments, the bendable device 12 includes a base 100 and a first rotating member 200, and the first rotating member 200 is configured to be rotatable relative to the base 100. The bendable device 12 may include two first rotating members 200 respectively disposed on both sides of the base 100, and the two first rotating members 200 may rotate toward or away from each other to achieve the bending or unfolding of the bendable device 12. The flexible member 11 of the foldable device 10 may be fixed to the two first rotating members 200 to achieve folding or unfolding synchronously with the rotation of the two first rotating members 200.

[0040] It should be noted that Figure 5 Only one optional bending angle of the bendable device 12 is shown. The bendable device 12 provided in the embodiment of the present application can also be bent to other angles as needed, including but not limited to 0-90 degrees. Similarly, the folding angle of the foldable device 10 is not limited to Figure 2 Fold angles shown.

[0041] See also Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the structure of a bendable device provided in some embodiments of the present application, Figure 7 yes Figure 6 Schematic diagram of the exploded structure of the bendable device in the embodiment.

[0042] In some embodiments, the bendable device 12 includes a base 100, a first rotating member 200, a second rotating member 300, a third rotating member 400, and a synchronous rotating member 500. The first rotating member 200, the second rotating member 300, the third rotating member 400, and the synchronous rotating member 500 can be arranged in pairs to cooperate to achieve the bending or unfolding of the bendable device 12.

[0043] Specifically, the bendable device 12 may include two second rotating members 300 and two synchronous rotating members 500, wherein the two second rotating members 300 are respectively connected to the two first rotating members 200 by transmission, and the two synchronous rotating members 500 are respectively connected to the two second rotating members 300 by transmission. The first rotating member 200 is connected to the synchronous rotating member 500 by transmission through the second rotating member 300.

[0044] Among them, the two synchronous rotating members 500 can be located between the two first rotating members 200 to achieve the synchronous movement of the two first rotating members 200. The synchronous rotating member 500 can include a synchronous gear 510, and the synchronous gears 510 of the two synchronous rotating members 500 are meshed, so that when one of them rotates, the other can rotate synchronously. The second rotating member 300 may include a convex tooth portion 301 meshed with the synchronous gear 510, so that when one second rotating member 300 rotates, the two synchronous rotating members 500 can rotate synchronously, thereby driving the other second rotating member 300 to rotate. Therefore, the two first rotating members 200 respectively connected to the two synchronous rotating members 500 can achieve synchronous rotation by means of the above-mentioned gear meshing relationship. In other embodiments of the present application, other structures can also be used to achieve synchronous rotation, such as a connecting rod mechanism. This embodiment is only described by taking the gear meshing structure as an example.

[0045] The bendable device 12 may include two third rotating members 400, both of which are rotatably connected to the base 100 and are rotatably connected to the two first rotating members 200, so that the two first rotating members 200 can rotate relative to the base 100. The rotational connection between the third rotating member 400 and the base 100, and the rotational connection between the third rotating member 400 and the first rotating member 200, can be achieved by a pin, which can be an independent device, such as the first shaft 21, and inserted into the shaft hole of the corresponding device; the pin can also be fixed on one of the two rotating devices, or integrally formed with one of the two rotating devices, such as the second shaft 22.

[0046] Optionally, the third rotating member 400 is provided with a second shaft 22 and is rotatably connected to the base 100 via the second shaft 22. The first shaft 21 is alternately provided through multiple locations of the third rotating member 400 and the first rotating member 200 provided with shaft holes to achieve rotatable connection between the first rotating member 200 and the third rotating member 400.

[0047] The first rotating member 200 may be connected to one end of the third rotating member 400 which is away from the other third rotating member 400 , and the two first rotating members 200 may be bent relative to each other with the base 100 as the center.

[0048] The first rotating member 200 of the bendable device 12 can be used as a component for connecting the flexible member 11 or the related frame, and can be folded and rotated through the above-mentioned matching structure with the base 100, the second rotating member 300, the third rotating member 400 and the synchronous rotating member 500, so that the bending state of the bendable device 12 can correspond to the folding state of the foldable device 10. The first rotating member 200 can be designed as a long strip or other shapes as needed to facilitate the connection with various components. Other structural features of the base 100, the first rotating member 200, the second rotating member 300 and the third rotating member 400 will be further described below.

[0049] The bendable device 12 may also include a torsion mechanism for achieving bending and suspension, including a first abutting member 610, a second abutting member 620 and an elastic member 630. The first abutting member 610 is provided with a passive cam 611, and the synchronous gear 510 of the synchronous rotating member 500 is provided with an active cam 511, and the active cam 511 contacts and cooperates with the passive cam 611. The second abutting member 620 may be arranged on a side of the first abutting member 610 away from the synchronous gear 510, and the elastic member 630 is arranged between the first abutting member 610 and the second abutting member 620, and abuts against the first abutting member 610 and the second abutting member 620, and is used to provide the first abutting member 610 with a force to abut against the synchronous gear 510, so that the passive cam 611 can abut against the active cam 511. Therefore, when the synchronous gear 510 rotates to the preset position, the rotational resistance between the active cam 511 and the passive cam 611 reaches a level that can achieve hovering, so that the bendable device 12 can be in a bent hovering state, and then the foldable device 10 can be in a folded hovering state.

[0050] The synchronous rotating member 500 may further include a guide rod 520 that penetrates the synchronous gear 510. The guide rod 520 may sequentially penetrate the first abutting member 610 and the elastic member 630, and be inserted into the second abutting member 620 to play a guiding role. The bendable device 12 may further include a connecting member 640, which is fixed to the base 100 and is located on a side of the synchronous gear 510 away from the first abutting member 610. One end of the guide rod 520 away from the second abutting member 620 may be inserted into the connecting member 640 to achieve the limiting of the synchronous rotating member 500.

[0051] Optionally, the bendable device 12 further includes a rotating shaft 650 and a limiting member 660. The rotating shaft 650 may be disposed through the connecting member 640, the synchronous rotating member 500, the first abutting member 610, the elastic member 630 and the second abutting member 620, and abut between the connecting member 640 and the base 100 to achieve rotation limiting of the synchronous rotating member 500 and the torque mechanism. The limiting member 660 may be sleeved on the portion of the rotating shaft 650 protruding from the second abutting member 620, and abut against the side of the second abutting member 620 away from the first abutting member 610, to achieve limiting between the second abutting member 620 and the rotating shaft 650.

[0052] In some embodiments, the base 100 can be used to install the third rotating member 400, the synchronous rotating member 500, the rotating shaft 650 and the above-mentioned torsion mechanism and other components. The base 100 can be in the shape of a long strip, so that each component can be arranged on the base 100. The base 100 can include a base 110, and a first limiting portion 120, a second limiting portion 130 and a third limiting portion 140 which are sequentially spaced and convexly arranged on the base 110. Among them, the area between the first limiting portion 120 and the second limiting portion 130 can be used to install the third rotating member 400, and the first limiting portion 120 and the second limiting portion 130 can limit the third rotating member 400. The area between the second limiting portion 130 and the third limiting portion 140 can be used to install the rotating shaft 650, the synchronous rotating member 500 and the above-mentioned torsion mechanism and other components, and the second limiting portion 130 and the third limiting portion 140 can limit the rotating shaft 650. The portion of the base 110 between the limiting portions may be provided with mounting structures corresponding to the components, such as convex portions, grooves, holes, etc., which will not be elaborated herein.

[0053] It should be noted that the technical features of the bendable device 12 not described in detail in the above embodiment are within the scope that can be easily obtained by those skilled in the art, so they are not described in detail.

[0054] See also Figures 8 to 11 , Figure 8 is a schematic diagram of the assembly structure of a first rotating member and a second rotating member of a bendable device in an unfolded state provided in some embodiments of the present application, Fig. 9 yes Figure 8 Schematic diagram of the exploded structure of some bendable devices in the embodiment, Fig.10 yes Figure 8 A further exploded structural diagram of some bendable devices in the embodiment, Fig.11 It is a schematic structural diagram of a bendable device in a bent state provided in some embodiments of the present application.

[0055] In some embodiments, the second rotating member 300 includes a main body 310 and a vibration damper 320 connected to each other. The vibration damper 320 forms the portion of the second rotating member 300 that contacts the first rotating member 200, and is used to reduce the vibration and abnormal sound generated by the second rotating member 300 and the first rotating member 200 during relative movement.

[0056] It should be noted that, in order to ensure that the bendable device 12 can be bent or unfolded smoothly, the first rotating member 200 and the second rotating member 300 are configured to move relative to each other, such as relative linear movement, during the bending process or the unfolding process of the bendable device 12. There is usually a movement gap between the first rotating member 200 and the second rotating member 300, so scratches are formed during the movement, thereby generating vibration and abnormal noise.

[0057] The embodiment of the present application designs the second rotating member 300 as the above structure, and makes the second rotating member 300 contact with the first rotating member 200 through its vibration-damping body 320, thereby preventing the main body 310 from scratching the first rotating member 200 during the movement. The vibration-damping body 320 in contact with the first rotating member 200 is made of a material that transmits vibration slowly, so it can reduce the vibration of the first rotating member 200 and the second rotating member 300 during the relative movement, thereby reducing or even eliminating the vibration abnormal sound.

[0058] Optionally, the material of the vibration damper 320 is plastic, which has good vibration damping performance. Of course, the vibration damper 320 can also be made of other materials that transmit vibration slowly, such as foam materials, metal elastomers, etc. The material of the main body 310 can be metal to meet the strength and rigidity requirements of the second rotating member 300. Of course, the main body 310 can also be made of other materials that can meet the requirements.

[0059] Generally speaking, in order to meet the requirements of strength and rigidity, the rotating parts in relative motion are usually made of metal materials, and when metal components are scratched during motion, they will produce very obvious vibration and abnormal noise. The bendable device 12 provided in the embodiment of the present application can greatly reduce the vibration and abnormal noise generated by the first rotating part 200 and the second rotating part 300 during relative motion through the above design.

[0060] Optionally, the first rotating member 200 includes a first supporting portion 210 and a second supporting portion 220 that are arranged opposite to each other, and a first limiting groove 201 and a second limiting groove 202 are respectively provided on two surfaces of the first supporting portion 210 and the second supporting portion 220 that are opposite to each other. Thus, the first limiting groove 201, the second limiting groove 202, and the space between the first supporting portion 210 and the second supporting portion 220 can constitute the installation and movement space of the second rotating member 300.

[0061] The main body 310 of the second rotating member 300 can be arranged between the first supporting portion 210 and the second supporting portion 220. The second rotating member 300 includes two damping bodies 320, which are respectively connected to the opposite ends of the main body 310 and are respectively at least partially arranged in the first limiting groove 201 and the second limiting groove 202. Thus, the second rotating member 300 can be limited in the first limiting groove 201 and the second limiting groove 202 by the two damping bodies 320. The first limiting groove 201 and the second limiting groove 202 can be two parallel sliding grooves. During the bending process or the unfolding process of the bendable device 12, the first rotating member 200 can move linearly along the extension direction of the first limiting groove 201 and the second limiting groove 202, and the two damping bodies 320 at the two ends of the main body 310 contact the groove walls of the first limiting groove 201 and the second limiting groove 202 during the movement.

[0062] It can be understood that in other embodiments of the present application, the second rotating member 300 may also include more than two vibration damping bodies 320 , at least one of which is disposed at one end of the main body 310 and at least one is disposed at the other end of the main body 310 .

[0063] Optionally, two opposite ends of the main body 310 are provided with connecting parts 311, and the two vibration dampers 320 are respectively connected with the two connecting parts 311. Specifically, the connecting part 311 can be a convex part provided on the side of the main body 310, and the vibration damper 320 can be provided with a groove adapted thereto, so that the vibration damper 320 can be sleeved on the connecting part 311. In other embodiments, the connecting part 311 can also be a groove provided on the side of the main body 310, and correspondingly, the vibration damper 320 is provided with a convex part adapted thereto and embedded in the connecting part 311. In addition, the vibration damper 320 can also be fixedly connected to the main body 310 by one or more of bonding, welding, etc.

[0065] In some embodiments, the damping body 320 may be provided with a first receiving groove 321, which is provided on the surface of the damping body 320 in contact with the groove wall of the first limiting groove 201 or the groove wall of the second limiting groove 202, and is used to receive lubricant. For example, if the lower surface of a damping body 320 contacts the groove wall of the first limiting groove 201, the lower surface may be provided with a first receiving groove 321 for storing lubricant, so that during the relative movement of the first rotating member 200 and the second rotating member 300, the damping body 320 and the groove wall of the first limiting groove 201 may be soaked with lubricant, which can reduce the friction between the two, thereby reducing vibration and weakening the vibration and abnormal sound generated by the movement of the first rotating member 200 and the second rotating member 300. The number of the first receiving grooves 321 may be one or more.

[0066] The first receiving groove 321 may be a groove extending in a zigzag manner, such as a wavy groove. The vibration damper 320 may be in a long strip shape, and the first receiving groove 321 may extend in a zigzag manner along the length direction of the vibration damper 320. Thus, the first receiving groove 321 can increase the lubricant receiving capacity, thereby extending the lubrication time.

[0067] Optionally, the first receiving groove 321 is provided on two opposite surfaces of the vibration damper 320, such as the upper surface and the lower surface of the vibration damper 320. The two opposite surfaces of the vibration damper 320 can contact with two groove walls of the first limiting groove 201 or the second limiting groove 202 respectively, and are lubricated by the lubricant stored in the first receiving groove 321.

[0068] In other embodiments, a lubricating sheet made of lubricating material may also be attached to the surface of the vibration damping body 320 that contacts the groove wall of the first limiting groove 201 or the groove wall of the second limiting groove 202 to achieve a lubricating effect.

[0069] It should be noted that the bendable device 12 provided in the embodiment of the present application is not limited to the above structure, and its first rotating member 200 and the second rotating member 300 can be any two components of the bendable device 12 that will move relative to each other during the bending process of the bendable device 12, and the relative movement can be relative movement or relative rotation, and is not limited to the above embodiment. For example, one of the first rotating member 200 and the second rotating member 300 can be a shaft of the bendable device 12, and the other can be a component that rotates with the shaft.

[0071] In some embodiments, the third rotating member 400 of the bendable device 12 is provided with an arc portion 410, and the arc portion 410 forms a rotational fit with the base 100. A second receiving groove 101 may be provided on the surface of the base 100 that contacts the arc portion 410, for receiving lubricant. Among them, the second receiving groove 101 may be arc-shaped. The arc-shaped second receiving groove 101 may extend along the movement trajectory of the arc portion 410, so that the contact surface of the arc portion 410 and the base 100 can be lubricated to the greatest extent, thereby reducing the vibration and abnormal sound generated by the base 100 and the third rotating member 400 during the relative movement.
