Description

Technical Field

[0001] This application relates to the field of folding device technology, and more particularly to hinge mechanisms and electronic devices. Background Technology

[0002] With the continuous development of technology, the number of foldable screen phones on the market is increasing, and they are gradually gaining favor among consumers. Foldable screen phones generally require a hinge mechanism to achieve the folding capability. However, the existing hinge mechanisms of foldable screen phones are complex in structure, have many parts, and are relatively expensive to manufacture. Summary of the Invention

[0003] This application provides a hinge mechanism and an electronic device.

[0004] On one hand, a hinge mechanism is provided, including a first synchronizing member, a second synchronizing member, a connecting member, and an elastic component. The first synchronizing member has a first protrusion on one side, and the first protrusion forms a gear structure. The second synchronizing member has a second protrusion on one side, and the second protrusion forms a gear structure. The connecting member is rotatably connected to the first and second synchronizing members, the rotation axes of the first and second synchronizing members are parallel, and the gear structures of the first and second protrusions mesh. The elastic component abuts against at least one of the first and second synchronizing members, and is used to generate elastic deformation along the extension direction of the rotation axis of the first synchronizing member during rotation of the first and second synchronizing members.

[0005] On the other hand, an electronic device is provided, including a flexible screen and any of the aforementioned hinge mechanisms. The flexible screen is located on one side of the hinge mechanism, with one part connected to a first synchronizing member and the other part connected to a second synchronizing member.

[0006] The hinge mechanism provided in this application embodiment uses a first synchronizing element and a second synchronizing element with parallel rotation axes. These elements mesh with each other via a gear structure on the first and second protrusions, achieving synchronous folding and unfolding. Simultaneously, an elastic component abutting against at least one of the first and second synchronizing elements provides force during synchronous rotation, subjecting them to damping force. This improves the user's feel during folding, combines the torque module and the synchronization module, reduces the number of components in the hinge mechanism, and simplifies its structure.

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

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

"And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more.

[0035] With the continuous development of technology, the mobile phone industry is gradually moving towards foldable screen phones. Based on the different folding directions, foldable screen phones can be divided into inward-folding screen phones and outward-folding screen phones.

[0036] Compared to inward-folding screen phones, outward-folding screen phones can eliminate one outer screen, thus reducing the overall thickness and weight of the foldable phone. However, outward-folding screen phones require more consideration than inward-folding screen phones.

[0037] The hinge mechanism of foldable phones is relatively complex, generally including components such as a synchronization module and a torque module. The synchronization module is used to realize the synchronous rotation of the foldable phone, while the torque module is used to provide torque during rotation, improving the user experience.

[0038] However, the synchronization module and torque module of foldable screen phones are generally independent modules, each performing its corresponding function, resulting in a large number of parts in the hinge mechanism and a more complex overall structure.

[0039] Based on this, embodiments of this application provide an electronic device that is capable of folding and unfolding. For example, the electronic device can be a foldable screen phone. The electronic device may include a flexible screen and a hinge mechanism. The flexible screen is located on one side of the hinge mechanism and connected to it. The hinge mechanism is capable of rotation, and the flexible screen can be folded and unfolded under the action of the hinge mechanism.

[0040] It is understood that the electronic device provided in the embodiments of this application may also include other components. For example, the electronic device may also include components such as a casing, a processor, and a battery, which will not be further described here.

[0041] The hinge mechanism in the electronic device provided in the embodiments of this application will be further described below. For example... Figure 1As shown, Figure 1 This is a schematic diagram of the overall structure of the hinge mechanism 100 provided in the embodiment of this application. The hinge mechanism 100 may include multiple support plates 10, which can be connected to a flexible screen (not shown in the figure) to support and fix the flexible screen.

[0042] It is understandable that the hinge mechanism 100 has an unfolded state and a folded state, such as Figure 2 As shown, Figure 2 for Figure 1 The three views shown depict the hinge mechanism 100 in its unfolded state. When the hinge mechanism 100 is in the unfolded state, multiple support plates 10 are on the same plane, forming a support plane. In this way, the flexible screen can be located on this support plane and maintain a flat state.

[0043] like Figure 3 As shown, Figure 3 for Figure 1 The three views shown depict the hinge mechanism 100 in its folded state. When the hinge mechanism 100 is in the folded state, the entire hinge mechanism 100 is folded along a certain axis, and multiple support plates 10 form multiple planes. For example, as shown... Figure 3 As shown, multiple support plates 10 form an arc surface that is approximately semi-cylindrical and two planes. At this point, the flexible screen (not shown in the figure) can be located... Figure 3 The outer side of the hinge mechanism 100 shown, surrounding the hinge mechanism 100, means that the electronic device can be an outward-folding screen mobile phone.

[0044] For example, the multiple support plates 10 can be made of titanium alloy. Because titanium alloy is lightweight and has high strength, it can reduce the weight of the hinge mechanism 100 and increase its strength. Of course, the support plates 10 can also be made of other materials. For example, the support plates 10 can also be made of materials such as stainless steel and aluminum alloy components.

[0045] like Figure 4 As shown, Figure 4 for Figure 1 The schematic diagram shows the overall structure of the hinge mechanism 100 on the other side. The hinge mechanism 100 may also include multiple decorative panels 20. When the hinge mechanism 100 is in the unfolded state, the multiple decorative panels 20 are located on one side of the multiple support plates 10 to conceal the internal structure of the hinge mechanism 100.

[0046] like Figure 5 As shown, Figure 5 for Figure 4The schematic diagram of the internal structure of the hinge mechanism 100 shown indicates that the hinge mechanism 100 may further include a synchronous torque module 30 and a synchronous connection assembly 40. When the hinge mechanism 100 is in the unfolded state, the synchronous torque module 30 and the synchronous connection assembly 40 may be located on one side of the plurality of support plates 10. The synchronous torque module 30 and the synchronous connection assembly 40 may be connected to the plurality of support plates 10 and the plurality of decorative plates 20. Figure 4 ) connect, so that multiple support plates 10 and decorative plates 20 ( Figure 4 They rotate synchronously.

[0047] The following is a detailed description of the structure of the aforementioned synchronous torque module 30 and synchronous connection component 40, as well as their cooperation with the support plate 10 and decorative plate 20.

[0048] like Figure 6 As shown, Figure 6 The present application provides a three-view and bottom view of a synchronous torque module 30. The synchronous torque module 30 may include a first synchronizing member 31, a second synchronizing member 32, a connecting member 33, and an elastic component 34. The connecting member 33 is rotatably connected to the first synchronizing member 31 and the second synchronizing member 32, and the rotation axes of the first synchronizing member 31 and the second synchronizing member 32 are parallel. Thus, the first synchronizing member 31 and the second synchronizing member 32 can rotate relative to the connecting member 33. For example, as shown... Figure 6 As shown, the rotation axes of the first synchronizing element 31 and the second synchronizing element 32 are parallel to each other. Figure 6 The X direction shown is parallel.

[0049] Continue to refer to Figure 6 The first synchronizing member 31 has a first protrusion 311 on one side, and a gear structure 301 is formed on the first protrusion 311. Simultaneously, the second synchronizing member 32 has a second protrusion 321 on one side, and a gear structure 301 is also formed on the second protrusion 321. The gear structure 301 of the first protrusion 311 and the gear structure 301 of the second protrusion 321 mesh.

[0050] Therefore, when one of the first synchronizing element 31 and the second synchronizing element 32 rotates around its own rotation axis, the other can rotate synchronously, thus achieving synchronous rotation of the first synchronizing element 31 and the second synchronizing element 32.

[0051] like Figure 6 As shown, the first synchronizing element 31 and the second synchronizing element 32 are arranged side by side. The first synchronizing element 31 and the second synchronizing element 32 are close to each other on one side through the gear structure 301 of the first protrusion 311 and the gear structure 301 of the second protrusion 321. The other side can move away from each other or move closer to each other during rotation, so as to realize the unfolding and folding of the first synchronizing element 31 and the second synchronizing element 32.

[0052] The first synchronization element 31 and the second synchronization element 32 can be synchronized with the support plate 10. Figure 5 The first synchronization element 31 can be connected to a portion of the flexible screen, and the second synchronization element 32 can be connected to another portion of the flexible screen. Thus, when the first synchronization element 31 and the second synchronization element 32 rotate, the flexible screen can also rotate.

[0053] Therefore, when the first synchronizer 31 and the second synchronizer 32 are respectively connected to one of the multiple support plates 10, the two support plates 10 can rotate synchronously. Since the support plates 10 can be connected to the flexible screen—that is, one part of the flexible screen is connected to the first synchronizer 31 and the other part is connected to the second synchronizer 32—the flexible screen can rotate synchronously, ultimately achieving synchronous folding of the electronic device. Simultaneously, due to the good synchronization between the first synchronizer 31 and the second synchronizer 32, the neutral layer of the flexible screen and the neutral layer of the hinge mechanism 100 can be on the same plane, ensuring that the neutral layer of the flexible screen is unaffected and guaranteeing the service life of the flexible screen.

[0054] Continue to refer to Figure 6 The elastic component 34 abuts against at least one of the first synchronizing member 31 and the second synchronizing member 32, and is used to generate elastic deformation along the extension direction of the first synchronizing member 31 and the rotation axis during the rotation of the first synchronizing member 31 and the second synchronizing member 32.

[0055] In this way, as the first synchronizer 31 and the second synchronizer 32 rotate around their own rotation axis, the elastic component 34 can exert a force on the first synchronizer 31 and the second synchronizer 32, so that the first synchronizer 31 and the second synchronizer 32 produce a damping effect during rotation, improving the feel of the electronic device during folding and unfolding, and enhancing the user experience.

[0056] Among them, such as Figure 6 As shown, the synchronous torque module 30 can form a symmetrical structure. In this way, when the synchronous torque module 30 is folded, the rotation axis of the whole is located in the middle position, and the user can better perceive the damping effect during rotation.

[0057] Therefore, in the hinge mechanism 100 provided in this application embodiment, the first synchronizing member 31 and the second synchronizing member 32, whose rotation axes are parallel, mesh with each other through the gear structure 301 of the first protrusion 311 and the second protrusion 321, realizing synchronous folding and unfolding between the first synchronizing member 31 and the second synchronizing member 32. At the same time, through the elastic component 34 that abuts against at least one of the first synchronizing member 31 and the second synchronizing member 32, a force can be provided during synchronous rotation. By using the damping force that the first synchronizing member 31 and the second synchronizing member 32 receive during rotation, the user's feel during folding is improved. This realizes the merging of the torque module and the synchronization module, thereby reducing the number of parts in the hinge mechanism 100 and simplifying the structure of the hinge mechanism 100.

[0058] In some embodiments, such as Figure 6 As shown, the first synchronizing member 31 also has a third protrusion 312 on the side where the first protrusion 311 is located. The third protrusion 312 and the first protrusion 311 are spaced apart along the extension direction of the rotation axis of the first synchronizing member 31. The second synchronizing member 32 also has a fourth protrusion 322 on the side where the second protrusion 321 is located. The fourth protrusion 322 and the second protrusion 321 are spaced apart along the direction of the rotation axis of the second synchronizing member 32.

[0059] like Figure 6 As shown, a portion of the elastic component 34 is located between the first protrusion 311 and the third protrusion 312, abutting against the first protrusion 311 and the third protrusion 312. Another portion of the elastic component 34 is located between the second protrusion 321 and the fourth protrusion 322, abutting against the second protrusion 321 and the fourth protrusion 322. The elastic component 34 can be used to generate elastic deformation along the rotation axis of the first synchronizing member 31 under the pressure of the first protrusion 311, the second protrusion 321, the third protrusion 312, and the fourth protrusion 322.

[0060] like Figure 6 As shown, the first protrusion 311 and the third protrusion 312 are spaced apart along the rotation axis of the first synchronizing member 31, and the second protrusion 321 and the fourth protrusion 322 are spaced apart along the rotation axis of the second synchronizing member 32. Thus, when the first protrusion 311, the second protrusion 321, the third protrusion 312, and the fourth protrusion 322 apply pressure to the elastic component 34, the elastic component 34 can generate elastic deformation along the extension direction of the rotation axis of the first synchronizing member 31. This allows the first synchronizing member 31 and the second synchronizing member 32 to provide force to the user during rotation, improving the user's feel during rotation.

[0061] In order for the first synchronizing element 31 and the second synchronizing element 32 to exert a force on the elastic component 34 during rotation, in some embodiments, such as Figure 6 As shown, the end faces of the first protrusion 311 and the third protrusion 312 that are close to each other both have a cam structure 302, and the end faces of the second protrusion 321 and the fourth protrusion 322 that are close to each other both have a cam structure 302.

[0062] The elastic component 34 may include a first latching member 341, a second latching member 342, and an elastic member 343. The first latching member 341 abuts against the cam structure 302 of the first protrusion 311 and the cam structure 302 of the second protrusion 321. The elastic member 343 is located on the side of the first latching member 341 away from the first protrusion 311 and the second protrusion 321, with one end abutting against the first latching member 341.

[0063] The second latching member 342 is located on the side of the elastic member 343 away from the first protrusion 311 and the second protrusion 321, and abuts against the other end of the elastic component 34. The second latching member 342 abuts against the cam structure 302 of the third protrusion 312 and the cam structure 302 of the fourth protrusion 322.

[0064] Thus, during the rotation of the first synchronizing member 31 and the second synchronizing member 32, the first locking member 341 and the second locking member 342 will be located at different positions of the cam structure 302, causing the first locking member 341 and the second locking member 342 to be displaced along the rotation axis of the first synchronizing member 31, thereby causing the elastic member 343 to undergo elastic deformation along the rotation axis of the first synchronizing member 31.

[0065] It is understood that the elastic element 343 is a component capable of elastic deformation. For example, such as... Figure 6 As shown, the elastic element 343 can be a spring, which is snapped between the first snap-fit ​​element 341 and the second snap-fit ​​element 342.

[0066] The number of elastic elements 343 can be set according to actual conditions. For example, such as... Figure 6 As shown, two springs are provided between the first latching member 341 and the second latching member 342, and the first latching member 341 and the second latching member 342 are respectively latched to the ends of the two springs. Of course, the number of elastic members 343 can also be one or other numbers.

[0067] Furthermore, it is understandable that, such as Figure 7 As shown, Figure 7 for Figure 6The three-view and bottom view of the first synchronizing member 31 show that the cam structure 302 on the end face of the first protrusion 311 and the third protrusion 312 that are close to each other can be a circumferentially spaced protrusion structure around the rotation axis of the first synchronizing member 31, and a recess is formed between adjacent protrusion structures.

[0068] Similarly, the cam structure 302 on the end faces of the second protrusion 321 and the fourth protrusion 322 that are close to each other are also circumferentially spaced protrusions around the rotation axis of the second synchronizing member 32, and recesses are formed between adjacent protrusions.

[0069] In this way, when the first synchronizing member 31 and the second synchronizing member 32 rotate synchronously, the first locking member 341 will abut against the recess or protrusion formed by the cam structure 302 of the first protrusion 311 and the cam structure 302 of the second protrusion 321, and the second locking member 342 will abut against the recess or protrusion formed by the cam structure 302 of the third protrusion 312 and the cam structure 302 of the fourth protrusion 322, so as to achieve a hovering effect during rotation, improve the user's feel during rotation, and provide a better experience.

[0070] Furthermore, in order to make it easier for the first latching member 341 and the second latching member 342 to abut against the aforementioned cam structure 302, such as Figure 6 As shown, the first latching member 341 and the second latching member 342 have protrusions on the side near the cam structure 302 in order to better cooperate with the cam structure 302.

[0071] Continue to refer to Figure 6 In order to enable the first synchronizing element 31 and the second synchronizing element 32 to be rotatably connected to the connecting element 33, in some embodiments, the connecting element 33 may include a first connecting shaft 35, a second connecting shaft 36, a first connecting element 37, and a second connecting element 38. The first connecting shaft 35 passes through the first protrusion 311 and the third protrusion 312, and the extending direction of the first connecting shaft 35 is parallel to the rotation axis of the first synchronizing element 31. The second connecting shaft 36 passes through the second protrusion 321 and the fourth protrusion 322, and the extending direction of the second connecting shaft 36 is parallel to the rotation axis of the second synchronizing element 32.

[0072] The first connector 37 is located on the side of the first protrusion 311 and the second protrusion 321 away from the elastic component 34, and is connected to the first connecting shaft 35 and the second connecting shaft 36. The second connector 38 is located on the side of the third protrusion 312 and the fourth protrusion 322 away from the elastic component 34, and is connected to the first connecting shaft 35 and the second connecting shaft 36.

[0073] Therefore, the first synchronizing element 31 can rotate around the first connecting shaft 35, and the second synchronizing element 32 can rotate around the second connecting shaft 36. Since both the first connecting shaft 35 and the second connecting shaft 36 are connected to the first connecting element 37 and the second connecting element 38, the first connecting shaft 35 and the second connecting shaft 36 are interconnected through the first connecting element 37 and the second connecting element 38, thereby connecting the first synchronizing element 31 and the second synchronizing element 32.

[0074] Among them, such as Figure 6 As shown, when the elastic element 343 consists of two springs, the two elastic elements 343 can be respectively sleeved on the outside of the first connecting shaft 35 and the second connecting shaft 36. In this way, the two elastic elements 343 can be fixed by the first connecting shaft 35 and the second connecting shaft 36, so that the elastic elements 343 do not shift.

[0075] In some embodiments, such as Figure 6 As shown, the first connector 37 may have a first clearance hole 371 and a second clearance hole 372. The second connector 38 may have a third clearance hole 381 and a fourth clearance hole 382. The first connecting shaft 35 may include a first shaft body 351, a first fixing part 352 and a second fixing part 353.

[0076] The first shaft body 351 passes through the first protrusion 311 and the third protrusion 312, and is disposed within the first clearance hole 371 and the third clearance hole 381. The first fixing part 352 is connected to the first shaft body 351, located on the side of the first connector 37 away from the first protrusion 311, and abuts against the first connector 37. The second fixing part 353 is connected to the first shaft body 351, located on the side of the second connector 38 away from the third protrusion 312, and abuts against the second connector 38. In this way, the first connecting shaft 35 will not detach from the first connector 37 and the second connector 38 along its extension direction, so that the first connecting shaft 35, the first connector 37, and the second connector 38 can be connected.

[0077] Similarly, such as Figure 6As shown, the second connecting shaft 36 includes a second shaft body 361, a third fixing part 362, and a fourth fixing part 363. The second shaft body 361 passes through the second protrusion 321 and the fourth protrusion 322, and is disposed within the second clearance hole 372 and the fourth clearance hole 382. The third fixing part 362 is connected to the second shaft body 361, located on the side of the first connecting member 37 away from the second protrusion 321, and abuts against the first connecting member 37. The fourth fixing part 363 is connected to the second shaft body 361, located on the side of the second connecting member 38 away from the fourth protrusion 322, and abuts against the second connecting member 38. In this way, the second connecting shaft 36 will not detach from the first connecting member 37 and the second connecting member 38 along its extension direction, allowing the second connecting shaft 36 to be connected to the first connecting member 37 and the second connecting member 38.

[0078] In order to facilitate the passage of the first connecting shaft 35 through the first protrusion 311 and the third protrusion 312, as follows: Figure 7 As shown, both the first protrusion 311 and the third protrusion 312 are provided with a fifth clearance hole 313, through which the first connecting shaft 35 can pass through the first protrusion 311 and the third protrusion 312.

[0079] Similarly, the second protrusion 321 and the fourth protrusion 322 may be provided with a sixth clearance hole (not shown in the figure) to facilitate the passage of the second connecting shaft 36 through the second protrusion 321 and the fourth protrusion 322.

[0080] In some embodiments, such as Figure 6 As shown, a first notch and a second notch are formed on one side of the second connector 38, spaced apart. The first notch and the second notch form the aforementioned third clearance hole 381 and fourth clearance hole 382. The opening size of the first notch is smaller than the size of the first shaft body 351, and the opening size of the second notch is smaller than the size of the second shaft body 361.

[0081] Thus, when installing the first connecting shaft 35, the first connecting shaft 35 can pass sequentially through the first clearance hole 371 of the first connecting member 37, and the fifth clearance hole 313 of the first protrusion 311 and the third protrusion 312. Figure 7 Then, the second connector 38 is forcibly engaged into the first shaft body 351 through the third clearance hole 381 on the second connector 38. Since the opening size of the first notch is smaller than the size of the first shaft body 351, the first shaft body 351 will not come out from the first notch.

[0082] Similarly, when installing the second connecting shaft 36, the second connecting shaft 36 can pass sequentially through the second clearance hole 372 of the first connecting member 37, and the fifth clearance holes (not shown in the figure) of the second protrusion 321 and the fourth protrusion 322. Then, the second connecting member 38 is forcibly snapped into the second shaft body 361 through the fourth clearance hole 382 on the second connecting member 38.

[0083] like Figure 5 As shown, the support plate 10 may include a fixing plate 11, which can be used to fix the synchronous torque module 30. Wherein, Figure 6 The first synchronizing element 31 is connected to one side of the first connecting shaft 35, and the second synchronizing element 32 is connected to one side of the second connecting shaft 36. Figure 5 On the fixing plate 11 shown.

[0084] To allow the first synchronizing element 31 and the second synchronizing element 32 to be mounted on the fixing plate 11, in some embodiments, such as... Figure 5 As shown, the hinge mechanism 100 may also include multiple cover plates 50, which are connected to the fixed plate 11.

[0085] Among them, such as Figure 5 As shown, the hinge mechanism 100 may include multiple synchronous torque modules 30, which are spaced apart along the extension direction of the fixed plate 11 and fixed to the fixed plate 11 by multiple cover plates 50.

[0086] like Figure 5 As shown, depending on the position of the cover plate 50, the multiple cover plates 50 may include two first cover plates 51 and a second cover plate 52 located between the two first cover plates 51.

[0087] like Figure 8 As shown, Figure 8 for Figure 5 The first cover plate 51 shown is close to the fixing plate 11 ( Figure 5 A schematic diagram of the overall structure on one side, with the upper cover plate 50 close to the fixing plate 11. Figure 5 One side of the first connecting shaft 35 has a first fixing groove 501 and a second fixing groove 502. The first fixing groove 501 can be used to fix the first connecting shaft 35. Figure 6 The second fixing groove 502 can be used to fix the second connecting shaft 36 at the end of the shaft. Figure 6 The end of ).

[0088] Similarly, such as Figure 9 As shown, Figure 9 for Figure 5 The second cover plate 52 shown is close to the fixing plate 11. Figure 5 A schematic diagram of the overall structure of one side of the second cover plate 52 near the fixing plate 11. Figure 5One side of the first connecting shaft 35 also has the aforementioned first fixing groove 501 and second fixing groove 502. The first fixing groove 501 can be used to fix the first connecting shaft 35. Figure 6 The second fixing groove 502 can be used to fix the second connecting shaft 36 at the end of the shaft. Figure 6 The end of ).

[0089] The two ends of the first connecting shaft 35 can be located in the first fixing groove 501 of the two adjacent cover plates 50 (i.e., the first cover plate 51 and the second cover plate 52), and the two ends of the second connecting shaft 36 are located in the second fixing groove 502 of the two adjacent cover plates 50 (the first cover plate 51 and the second cover plate 52).

[0090] In this way, the first fixing groove 501 and the second fixing groove 502 of the cover plate 50 can provide installation positions for the first connecting shaft 35 and the second connecting shaft 36, so that the two ends of the first connecting shaft 35 and the two ends of the second connecting shaft 36 can be engaged between the cover plate 50 and the fixing plate 11, thereby enabling the first synchronizing member 31 and the second synchronizing member 32 to be set on the fixing plate 11 for folding and unfolding.

[0091] As mentioned above, since the first cover plate 51 and the second cover plate 52 are located in different positions, the number of the first fixing groove 501 and the second fixing groove 502 on the first cover plate 51 and the second cover plate 52 are different. Figure 8 As shown, the first cover plate 51 may have a first fixing groove 501 and a second fixing groove 502. Figure 9 As shown, the second cover plate 52 may have two first fixing grooves 501 and second fixing grooves 502.

[0092] At the same time, in order to facilitate the positioning of the cover plate 50, such as Figure 8 and Figure 9 As shown, the first cover plate 51 and the second cover plate 52 are close to the fixing plate 11. Figure 5 One side of the cover plate 51 has a cover plate positioning post 503. Correspondingly, the fixing plate 11 has a corresponding positioning groove or positioning hole. In this way, when installing the first cover plate 51 and the second cover plate 52, the first cover plate 51 and the second cover plate 52 can be set in the corresponding positions by the cover plate positioning post 503, making the installation more convenient.

[0093] like Figure 8 and Figure 9 As shown, the first cover plate 51 and the second cover plate 52 are also provided with cover plate mounting holes 504. Correspondingly, the fixing plate 11 ( Figure 5 The corresponding mounting holes are also provided on it (not shown in the figure).

[0094] like Figure 5As shown, the hinge mechanism 100 may also include a screw 60. The screw 60 can extend into the cover plate mounting hole 504 of the cover plate 50. Figure 8 The cover plate 50 is threadedly connected to the fixing plate 11 and the mounting holes of the fixing plate 11. In this way, the cover plate 50 is fixed to the fixing plate 11 by screws 60.

[0095] like Figure 10 and Figure 11 As shown, Figure 10 for Figure 8 The diagram shows the overall structure of the first cover plate 51 on the other side. Figure 11 for Figure 9 The diagram shows the overall structure of the second cover plate 52 on the other side. The first cover plate 51 and the second cover plate 52 are away from the fixing plate 11 ( Figure 5 One side of the ) has a dispensing groove 505.

[0096] In addition, in order to limit the rotation angle of the first synchronizing member 31 and the second synchronizing member 32, such as Figure 6 As shown, the first synchronizing member 31 has a first abutting protrusion 314 on the side near the first connecting shaft 35, and the second synchronizing member 32 has a second abutting protrusion 324 on the side near the second connecting shaft 36.

[0097] Thus, as Figure 12 As shown, Figure 12 This diagram illustrates the positional relationship between the first synchronizer 31, the second synchronizer 32, and the fixed plate 11 when the hinge mechanism 100 is in the display and folded states. When the hinge mechanism 100 is in the unfolded state, the first abutting protrusion 314 and the second abutting protrusion 324 abut against the fixed plate 11, restricting the first synchronizer 31 and the second synchronizer 32 from continuing to rotate, thus limiting the rotation.

[0098] like Figure 5 As shown, the multiple support plates 10 may further include a first connecting plate 12 and a second connecting plate 13. When the hinge mechanism 100 is in the unfolded state, the first connecting plate 12 and the second connecting plate 13 may be located on opposite sides of the fixed plate 11. The first connecting plate 12 may be connected to a portion of the flexible screen (not shown in the figure), and the second connecting plate 13 may be connected to another portion of the flexible screen (not shown in the figure). The first connecting plate 12 and the second connecting plate 13 can be used to drive the flexible screen (not shown in the figure) to fold.

[0099] To achieve synchronous rotation of the first connecting plate 12 and the second connecting plate 13, such as Figure 6 As shown, the first synchronizing member 31 has a first slider 315 on the side away from the first connecting shaft 35, and the second synchronizing member 32 has a second slider 325 on the side away from the second connecting shaft 36.

[0100] Correspondingly, such as Figure 13 As shown, Figure 13 This is a schematic diagram of the overall structure of the first connecting plate 12 and the second connecting plate 13 near the first synchronizing member 31 and the second synchronizing member 32. A first sliding groove 121 is formed on one side of the first connecting plate 12. The first slider 315 (… Figure 6 It is located in the first slide groove 121 and is slidably connected to the first connecting plate 12 in a direction perpendicular to the rotation axis of the first synchronizing member 31.

[0101] A second groove 131 is formed on one side of the second connecting plate 13, and a second slider 325 is formed thereon. Figure 6 It is located in the second slide groove 131 and is slidably connected to the second connecting plate 13 in a direction perpendicular to the rotation axis of the second synchronizing member 32.

[0102] Thus, as the first synchronizing element 31 and the second synchronizing element 32 rotate synchronously, the first slider 315 and the second slider 325 slide within the first groove 121 and the second groove 131 respectively, applying force to the groove walls of the first groove 121 and the second groove 131, thereby enabling the first connecting plate 12 and the second connecting plate 13 to rotate synchronously. Therefore, with the synchronous rotation of the first connecting plate 12 and the second connecting plate 13, the flexible screen can also be folded and unfolded synchronously.

[0103] When the hinge mechanism 100 is applied to an outward-folding screen phone, the first connecting plate 12 and the second connecting plate 13 will slide relative to the first synchronizing member 31 and the second synchronizing member 32 to a certain extent, resulting in a displacement. Therefore, as Figure 13 As shown, the first slide groove 121 and the second slide groove 131 can be inclined. When the first connecting plate 12 and the second connecting plate 13 rotate, they can slide and generate a certain amount of displacement.

[0104] like Figure 4 As shown, the multiple decorative panels 20 may include a first decorative panel 21, a second decorative panel 22, and a third decorative panel 23. The third decorative panel 23 can be connected to the fixed plate 11. When the hinge mechanism 100 is in the display state, the first decorative panel 21 can be positioned opposite to the first connecting plate 12, and the second decorative panel 22 can be positioned opposite to the second connecting plate 13. The first decorative panel 21 and the second decorative panel 22 can be used to cover the synchronous torque module 30 (…). Figure 5 ) and synchronous connection component 40 ( Figure 5 ).

[0105] like Figure 14 As shown, Figure 14This is a schematic diagram showing the connection between the first synchronous connector 71 and the first decorative panel 21 and the second decorative panel 22. The hinge mechanism 100 also includes multiple first synchronous connectors 71. One end of each first synchronous connector 71 is rotatably connected to the fixed plate 11, and the rotation axis of the first synchronous connector 71 is parallel to that of the first synchronous connector 31. Figure 13 The rotation axes of the two decorative panels are parallel. The first decorative panel 21 is connected to a portion of the first synchronous connector 71, and the second decorative panel 22 is connected to another portion of the first synchronous connector 71.

[0106] like Figure 14 As shown, a portion of the first synchronous connector 71 is disposed opposite to the first decorative panel 21, and another portion of the first synchronous connector 71 is disposed opposite to the second decorative panel 22. The first synchronous connector 71 disposed opposite to the first decorative panel 21 is connected to the first decorative panel 21, and the first synchronous connector 71 disposed opposite to the second decorative panel 22 is connected to the second decorative panel 22, so that the first decorative panel 21 and the second decorative panel 22 can rotate under the drive of the first synchronous connector 71.

[0107] To achieve synchronous rotation of the first decorative panel 21 and the second decorative panel 22, such as Figure 14 As shown, a connecting slider 711 is formed at the other end of the first synchronizing element 31. Correspondingly, as... Figure 15 As shown, Figure 15 This is a schematic diagram of the overall structure of the first connecting plate 12 and the second connecting plate 13 near the first decorative plate 21 and the second decorative plate 22. A third groove (not shown in the figure) is formed on one side of the first connecting plate 12, and a fourth groove 132 is formed on one side of the second connecting plate 13.

[0108] One portion of the connecting slider 711 of the first synchronization connector 71 is located in the third slide groove and is slidably connected to the first connecting plate 12 in a direction perpendicular to the rotation axis of the first synchronization member 31. The other portion of the connecting slider 711 of the first synchronization connector 71 is located in the fourth slide groove 132 and is slidably connected to the second connecting plate 13 in a direction perpendicular to the rotation axis of the second synchronization member 32.

[0109] As described above, the first decorative panel 21 and the first connecting plate 12 are arranged opposite to each other, and the second decorative panel 22 and the second connecting plate 13 are arranged opposite to each other. Correspondingly, the connecting slider 711 of the first synchronous connector 71 connected to the first decorative panel 21 can be located in the third groove of the first connecting plate, and the connecting slider 711 of the first synchronous connector 71 connected to the second decorative panel 22 can be located in the fourth groove 132.

[0110] Thus, one end of the first synchronous connector 71 is rotatably connected to the fixed plate 11, and the other end is slidably connected to the first connecting plate 12 or the second connecting plate 13. The first synchronous connector 71 can rotate synchronously with the rotation of the first connecting plate 12 and the second connecting plate 13. Since the first decorative plate 21 and the second decorative plate 22 are connected to multiple first synchronous connectors 71, the first decorative plate 21 and the second decorative plate 22 can rotate synchronously under the drive of the first connecting plate 12 and the second connecting plate 13.

[0111] In some embodiments, such as Figure 9 As shown, the second cover plate 52 has multiple synchronous shafts 521. The extending direction of the synchronous shafts 521 is the same as that of the first synchronous member 31. Figure 13 The direction of extension of the rotation axis of ) is parallel. Correspondingly, such as Figure 16 As shown, Figure 16 This is a schematic diagram of the overall structure of the first synchronous connector 71 provided in the embodiment of this application. One end of the first synchronous connector 71 has a first arc groove 712.

[0112] Thus, one end of the first synchronous connector 71 can be located between the synchronous shaft 521 and the fixed plate 11, and the groove wall of the first arc groove 712 is set around the synchronous shaft 521. Therefore, through the first arc groove 712, one end of the first synchronous connector 71 can rotate around the connecting shaft.

[0113] It is understandable that a synchronous shaft 521 can also be provided on the first cover plate 51, and the specific structure of the cover plate 50 can be adjusted according to the setting position of the first synchronous connector 71. For example, Figure 17 As shown, Figure 17 This is a schematic diagram of the overall structure when the first synchronous connector 71 is installed on the fixed plate 11 and the first connecting plate 12. The first synchronous connector 71 is located in the middle of the fixed plate 11. Therefore, as shown... Figure 9 As shown, the second cover plate 52 is provided with a synchronous shaft 521 and a first synchronous connector 71 ( Figure 17 )Cooperate.

[0114] In some embodiments, such as Figure 14 As shown, the hinge mechanism 100 may further include a decorative panel fixing block 72 and a decorative panel fixing piece 73. The decorative panel fixing block 72 is fixedly connected to the first synchronous connector 71 by screws 60. The decorative panel fixing piece 73 and the decorative panel fixing block 72 are connected by screws 60, and the decorative panel fixing piece 73 can be bonded to the first decorative panel 21 or the second decorative panel 22 by adhesive application.

[0115] In this way, the first decorative panel 21 and the second decorative panel 22 are connected to the first synchronous connector 71 through the decorative panel fixing block 72 and the decorative panel fixing piece 73. Of course, the first decorative panel 21 and the second decorative panel 22 can also be directly connected to the first synchronous connector 71.

[0116] like Figure 2 As shown, the multiple support plates 10 may further include a first idler plate 14 and a second idler plate 15. When the hinge mechanism 100 is in the unfolded state, the first idler plate 14 may be located between the first connecting plate 12 and the fixing plate 11, and the second idler plate 15 may be located between the second connecting plate 13 and the fixing plate 11. The first idler plate 14 and the second idler plate 15 may also be used to support and fix the flexible screen.

[0117] The synchronous connection component 40 can be used to make the first idler plate 14 and the second idler plate 15 rotate synchronously. Figure 5 As shown, there are multiple synchronous connection components 40.

[0118] In some embodiments, such as Figure 18 As shown, Figure 18 This is a schematic diagram showing the connection between the synchronous connection component 40 and the fixed plate 11. The synchronous connection component 40 includes a second synchronous connector 41 and a third synchronous connector 42. Wherein, as... Figure 5 As shown, one part of the second synchronization connector 41 is connected to the first connecting plate 12, and the other part of the second synchronization connector 41 is connected to the second connecting plate 13.

[0119] like Figure 8 and Figure 9 As shown, the first cover plate 51 and the second cover plate 52 are close to the fixing plate 11. Figure 5 Multiple second circular arc grooves 506 are formed on one side of the surface. Figure 5 It can be seen that the hinge mechanism 100 has a symmetrical structure as a whole. Therefore, for example, as shown in the figure... Figure 8 and Figure 9 As shown, the first cover plate 51 and the second cover plate 52 each form two second arcuate grooves 506. Meanwhile, as... Figure 19 As shown, Figure 19 This is a schematic diagram of the overall structure of the second synchronous connector 41 provided in the embodiment of this application. The second synchronous connector 41 has a third arc groove 411 formed on the side near the first connecting plate 12 or the second connecting plate 13.

[0120] Correspondingly, such as Figure 20 As shown, Figure 20 This is a schematic diagram of the overall structure of the third synchronous connector 42 provided in the embodiment of this application. The third synchronous connector 42 has a first limiting protrusion 421 and a second limiting protrusion 422.

[0121] like Figure 21As shown, Figure 21 This is a cross-sectional view of the second synchronous connector 41 and the third synchronous connector 42 when the hinge mechanism 100 is in the unfolded and folded states. The first limiting protrusion 421 and the second limiting protrusion 422 of the third synchronous connector 42 are rotatably connected to the second arc groove 506 and the third arc groove 411, respectively, and the rotation axis of the third synchronous connector 42 is parallel to that of the first synchronous connector 31. Figure 5 The rotation axes of the first connecting plate 12 and the second connecting plate 13 are parallel. In this way, when the first connecting plate 12 and the second connecting plate 13 rotate, they will drive the third synchronous connecting member 42 to rotate synchronously.

[0122] The first inert plate 14 is connected to a portion of the third synchronization connector 42, and the second inert plate 15 is connected to another portion of the third synchronization connector 42. For example, the first inert plate 14 and the second inert plate 15 can be connected to the third synchronization connector 42 by welding.

[0123] Therefore, since the third synchronous connector 42 will rotate under the drive of the first connecting plate 12 and the second connecting plate 13, and the first idler plate 14 and the second idler plate 15 are connected to the third synchronous connector 42, the first idler plate 14 and the second idler plate 15 can rotate synchronously under the drive of the third synchronous connector 42.

[0124] It is understandable that, such as Figure 5 As shown, a portion of the third synchronous connection 42 is disposed opposite to the first idler plate 14, and another portion of the third synchronous connection 42 is disposed opposite to the second idler plate 15. The third synchronous connection 42 disposed opposite to the first idler plate 14 can be connected to the first idler plate 14, and the third synchronous connection 42 disposed opposite to the second idler plate 15 can be connected to the second idler plate 15, so as to drive the first idler plate 14 and the second idler plate 15 to rotate.

[0125] In addition, such as Figure 8 and Figure 9 As shown, the second arc groove 506 has a third limiting protrusion 507, and the third arc groove 411 has a fourth limiting protrusion 412. The third limiting protrusion 507 can abut against the first limiting protrusion 421 to restrict its rotation within the second arc groove 506, and the fourth limiting protrusion 412 can abut against the second limiting protrusion 422 to restrict its rotation within the third arc groove 411, thereby limiting the rotation of the first connecting plate 12 ( Figure 5 ) and second connecting plate 13 ( Figure 5 The displacement of the hinge mechanism ensures dimensional consistency during folding and unfolding.

[0126] It is understandable that, such as Figure 1As shown, when the hinge mechanism 100 is in the unfolded state, the first connecting plate 12 and the second connecting plate 13 are located on both sides of the fixed plate 11, and the first idler plate 14 and the second idler plate 15 are also located on both sides of the fixed plate 11. Therefore, referring to... Figure 5 Multiple synchronous connection components 40 are also distributed on both sides of the fixed plate 11. Multiple synchronous connection components 40 on one side are connected to the first connecting plate 12 and the first idler plate 14, and synchronous connection components 40 on the other side are connected to the second connecting plate 13 and the second idler plate 15.

[0127] Based on the above description, referring to Figure 5 The hinge mechanism 100 provided in this application embodiment, during folding and unfolding, can drive the first connecting plate 12 and the second connecting plate 13 to rotate synchronously through the synchronous torque module 30, thereby driving the flexible screen (not shown in the figure) to rotate synchronously, so that the neutral layer of the hinge mechanism 100 and the neutral layer of the flexible screen are on the same plane, the neutral layer of the flexible screen is not affected, and thus the service life of the flexible screen is improved. Wherein, as Figure 5 As shown, by setting multiple synchronous torque modules 30, the hinge mechanism 100 is subjected to more uniform force during rotation, making rotation more convenient. Furthermore, the rotation axis of the hinge mechanism 100 is located in the center position, resulting in better perception of the consistency of the rotation process.

[0128] And such Figure 6 As shown, in the synchronous torque module 30 provided in this embodiment, the first synchronizing element 31 and the second synchronizing element 32 are engaged by a gear structure 301, ensuring that the first synchronizing element 31 and the second synchronizing element 32 can rotate synchronously. Simultaneously, the elastic component 34 of the synchronous torque module 30 can provide force during rotation, improving the user's feel. Therefore, Figure 6 The synchronous torque module 30 shown combines the synchronous module and the torque module, reducing the number of parts in the hinge mechanism 100 and simplifying its structure.

[0129] Reference Figure 21 Through the movement of the first limiting protrusion 421 within the second arc groove 506 and the movement of the second limiting protrusion 422 within the third arc groove 411, the first idler plate 14 and the second idler plate 15 can rotate synchronously with the first connecting plate 12 and the second connecting plate 13. Furthermore, through... Figure 8 The third limiting protrusion 507 shown and Figure 19 The fourth limiting protrusion 412 shown can limit the displacement of the first limiting protrusion 421 and the second limiting protrusion 422, thereby limiting the displacement of the first connecting plate 12 and the second connecting plate 13, and ensuring the dimensional consistency of the hinge mechanism 100 during the unfolding and folding process.

[0130] In addition, through Figure 16The first synchronous connector 71 shown allows the first decorative plate 21 and the second decorative plate 22 to rotate synchronously with the rotation of the first connecting plate 12 and the second connecting plate 13, so as to cover the internal structure of the hinge mechanism 100 and ensure the overall appearance of the hinge mechanism 100.

[0131] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
