Description

Technical Field

[0001] The present application belongs to the technical field of communication equipment, and specifically relates to an electronic device. Background Art

[0002] With the development of science and technology, people are becoming more and more dependent on electronic devices. In pursuit of a better visual experience, the size of flexible screens of electronic devices is getting bigger and bigger. The problem that arises is that the size of electronic devices is getting bigger and bigger, and their portability and comfort are greatly reduced.

[0003] In order not to affect the portability and comfort of electronic devices, foldable screen electronic devices are increasingly being used. However, for foldable screen electronic devices, since the flexible screen of the foldable screen electronic device has a fixed size, the foldable screen lacks support when unfolded, and is prone to interference or lack of storage space when folded. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the prior art that the flexible screen of the electronic device lacks support when unfolded and is prone to interference or lack of storage space when folded.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of the present application provides an electronic device, including a first housing, a second housing, a flexible screen, a rotating shaft mechanism, and a telescopic support mechanism;

[0007] The hinge mechanism is rotatably connected between the first housing and the second housing to enable the electronic device to switch between a folded state and an unfolded state;

[0008] The flexible screen includes a first sub-screen mounted on the first housing, a second sub-screen mounted on the second housing, and a bending portion connecting the first sub-screen and the second sub-screen;

[0009] The telescopic support mechanism is arranged in the rotating shaft mechanism;

[0010] When the electronic device is in the folded state, the telescopic support mechanism is away from the bending portion and forms a gap with the bending portion; when the electronic device is in the unfolded state, the telescopic support mechanism abuts against the bending portion to support the bending portion.

[0011] In the embodiment of the present application, the first shell and the second shell are used to carry the flexible screen and other necessary functional devices, and the setting of the hinge mechanism is used to realize the rotation connection between the first shell and the second shell, thereby realizing the folding or unfolding of the flexible screen. The flexible screen includes a first sub-screen, a second sub-screen and a bending portion, the first sub-screen is mounted on the first shell, the second sub-screen is mounted on the second shell, and the bending portion is between the first sub-screen and the second sub-screen to realize the connection between the first sub-screen and the second sub-screen. The telescopic support mechanism is rotatably connected with the hinge mechanism, and performs telescopic movement with the rotation of the hinge mechanism driven by the hinge structure, and switches between the first position and the second position of the hinge mechanism. When the electronic device is in a folded state, the telescopic support mechanism is in a retracted state, and a gap is formed between the bending portion and the first position; when the electronic device is in an unfolded state, the telescopic support mechanism is in an unfolded state, in a second position, and abuts against the bending portion to support the bending portion. The problem of insufficient or excessive screen size caused by different rotation radii during the folding process of the flexible screen is avoided, and the screen is prevented from being scratched or wrinkled.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0026] See also Figures 1 to 9, an embodiment of the present application provides an electronic device, comprising a first housing 10, a second housing 20, a flexible screen 30, a hinge mechanism 40 and a telescopic support mechanism 50, wherein the first housing 10 and the second housing 20 are rotatably connected via the hinge mechanism 40;

[0027] The flexible screen 30 includes a first sub-screen 31 mounted on the first housing 10 , a second sub-screen 32 mounted on the second housing 20 , and a bending portion 33 connecting the first sub-screen 31 and the second sub-screen 32 ;

[0028] The telescopic support mechanism 50 is disposed on the rotating shaft mechanism 40 and is rotatably connected to the rotating shaft mechanism 40. The telescopic support mechanism 50 performs telescopic movement as the rotating shaft mechanism 40 rotates, and switches between a first position and a second position of the rotating shaft mechanism 40.

[0029] When the electronic device is in a folded state, the telescopic support mechanism 50 is in a retracted state and is located at a first position away from the bending portion 33, and a gap is formed between the telescopic support mechanism 50 and the bending portion 33; when the electronic device is in an unfolded state, the telescopic support mechanism 50 is in an extended state and is located at a second position, and the telescopic support mechanism 50 abuts against the bending portion 33 to support the bending portion 33.

[0030] In the embodiment of the present application, the first shell 10 and the second shell 20 are used to carry the flexible screen 30 and other necessary functional components. The setting of the hinge mechanism 40 is used to realize the rotation connection between the first shell 10 and the second shell 20, thereby realizing the folding or unfolding of the flexible screen 30. The flexible screen 30 includes a first sub-screen 31, a second sub-screen 32 and a bending portion 33. The first sub-screen 31 is installed on the first shell 10, and the second sub-screen 32 is installed on the second shell 20. The bending portion 33 is between the first sub-screen 31 and the second sub-screen 32 to realize the connection between the first sub-screen 31 and the second sub-screen 32. The telescopic support mechanism 50 is rotationally connected to the hinge mechanism 40, and performs telescopic movement with the rotation of the hinge mechanism under the drive of the hinge structure 40, and switches between the first position and the second position of the hinge mechanism 40. When the electronic device is in a folded state, the telescopic support mechanism 50 is in a retracted state, and a gap is formed between the telescopic support mechanism 50 and the bending portion 33, and the telescopic support mechanism 50 is in a first position; when the electronic device is in an unfolded state, the telescopic support mechanism 50 is in an unfolded state, in a second position, and abuts against the bending portion 33 to support the bending portion 33. This avoids the problem of insufficient or excessive screen size caused by different rotation radii during the external folding process of the flexible screen 30, and avoids screen damage and wrinkles.

[0031] It should be noted that, when the electronic device is switched from the folded state to the unfolded state, the telescopic support mechanism 50 moves toward the direction close to the bending portion 33 until it abuts against the bending portion 33, thereby providing support for the flexible screen 30. When the electronic device is switched from the unfolded state to the folded state, the telescopic support mechanism 50 moves toward the direction away from the bending portion 33, thereby avoiding interference of the telescopic support mechanism 50 with the bending of the bending portion 33 and providing a certain accommodation space for the bending of the bending portion 33.

[0032] Optionally, in the embodiment of the present application, the shaft mechanism 40 includes a first shaft assembly 41 and a second shaft assembly 42 which are rotatably connected, the first shaft assembly 41 is mounted on the first housing 10, and the second shaft assembly 42 is mounted on the second housing 20;

[0033] Two ends of the telescopic support mechanism 50 are respectively connected to the first rotating shaft assembly 41 and the second rotating shaft assembly 42 . The telescopic support mechanism 50 moves closer to or farther from the bending portion 33 as the first rotating shaft assembly 41 and the second rotating shaft assembly 42 rotate relative to each other.

[0034] In the embodiment of the present application, the first rotating shaft assembly 41 is used to connect the first housing 10, and the second rotating shaft assembly 42 is used to connect the second housing 20. The relative rotation of the first rotating shaft assembly 41 and the second rotating shaft assembly 42 can drive the electronic device to switch between the folded state and the unfolded state. The two ends of the telescopic support mechanism 50 are respectively connected to the first rotating shaft assembly 41 and the second rotating shaft assembly 42. The telescopic support mechanism 50 shrinks or stretches as the first rotating shaft assembly 41 and the second rotating shaft assembly 42 rotate relative to each other, thereby making the telescopic support mechanism 50 away from or close to the bending portion 33. When the electronic device is in the folded state, the telescopic support mechanism 50 is in the first position, and can avoid the bending portion 33 in time to avoid the telescopic support mechanism 50 interfering with the bending of the bending portion 33, or can make enough bending space for the bending of the bending portion 33. The bending space here is the space left when the bending portion 33 is folded, specifically to avoid folding of the bending portion 33 due to insufficient storage space during the folding process. When the electronic device is in the unfolded state, the telescopic support mechanism 50 is in the second position and can provide support for the bending portion 33 to prevent the bending portion 33 from collapsing due to lack of supporting force.

[0035] Optionally, in the embodiment of the present application, the first rotating shaft assembly 41 includes a first rotating component 412, and the first rotating component 412 is connected to the first housing 10, and the second rotating shaft assembly 42 includes a second rotating component, and the second rotating component is connected to the second housing 20;

[0036] The first rotating member 412 is provided with a first gear 4123 , and the second rotating member is provided with a second gear. The first gear 4123 is rotatably meshed with the second gear.

[0037] In the embodiment of the present application, the first rotating component 412 is connected to the first housing 10, and the second rotating component is connected to the second housing 20. The first housing 10 and the second housing 20 rotate respectively with the rotation of the first rotating component 412 and the second rotating component. The mutually meshing first gear 4123 and the second gear are arranged to realize the rotation between the second rotating component and the second rotating component. When the first gear 4123 and the second gear rotate relative to each other, the first rotating component 412 and the second transmission component rotate relative to each other, driving the first housing 10 and the second housing 20 to rotate relative to each other, thereby driving the electronic device to switch between the folded state and the unfolded state, and also driving the telescopic support mechanism 50 to switch between the retracted state and the unfolded state, so as to realize that the telescopic support mechanism 50 is away from or close to the bending portion 33.

[0038] Optionally, in the embodiment of the present application, the telescopic support mechanism 50 includes a support member 51, a first telescopic member 52, and a second telescopic member 53, and the first telescopic member 52 and the second telescopic member 53 are respectively arranged on two opposite sides of the support member 51;

[0039] The first gear 4123 is provided with a first connecting column, and the second gear is provided with a second connecting column. The first connecting column and the center of the first gear 4123 have a first distance, and the second connecting column and the center of the second gear have a first distance.

[0040] The first telescopic member 52 is rotatably connected to the first connecting post, and the second telescopic member 53 is rotatably connected to the second connecting post.

[0041] In the embodiment of the present application, the support member 51 is used to provide support for the bending portion 33 when the telescopic support mechanism 50 is in the extended state, and is also used to provide a certain space for the bending portion 33 in a direction perpendicular to the first shell 10 when the telescopic support mechanism 50 is in the retracted state, so that the bending portion 33 has a certain accommodation space in the direction perpendicular to the first shell 10. The first telescopic portion and the second telescopic portion are respectively arranged on opposite sides of the support member 51, and the first telescopic portion and the second telescopic portion are arranged to expand the bending portion 33 when the telescopic support mechanism 50 is in the extended state, and provide certain support for the elongated bending portion 33. A first connecting column is provided on the first gear 4123, and a second connecting column is provided on the second gear, and the first connecting column and the second connecting column are respectively at a first distance from the center of the first gear 4123 and the center of the second gear. It can be understood that the first connecting column and the second connecting column are eccentrically arranged on the first gear 4123 and the second gear. When the flexible screen 30 electronic device is in a folded state, the support member 51 will be away from the bending portion 33, and can thus avoid the bending portion 33 in time to avoid interference caused by the bending of the bending portion 33 of the telescopic support mechanism 50, or sufficient bending space can be left for the bending of the bending portion 33; when the electronic device is in an unfolded state, the support member 51 will be close to the bending portion 33 and abut against the bending portion 33, so that the support member 51 supports the bending portion 33.

[0042] It should be noted that the arrangement of the first gear 4123 and the second gear that are meshed with each other enables the telescopic member to reciprocate as the gears rotate, and the eccentric arrangement of the first connecting column and the second connecting column allows the telescopic support mechanism 50 to provide different functions for the bending portion 33 in different states, so that the telescopic support mechanism 50 is in a retracted state and an unfolded state when the electronic device is in a folded state and an unfolded state, respectively, and then the support member 51, the first telescopic member 52 and the second telescopic member 53 provide a clearance space or support for the bending portion 33.

[0043] It should also be noted that, in practical applications, either the first connecting column or the second connecting column may be disposed in an eccentric manner, and this embodiment does not impose any limitation thereto.

[0044] Optionally, in an embodiment of the present application, the support member 51 includes a first connection portion 511, a second connection portion 512 and a support portion 513, the first telescopic member 52 and the second telescopic member 53 are respectively connected to both sides of the first connection portion 511, the first end of the second connection portion 512 is connected to the middle of the first connection portion 511, the second end of the second connection portion 512 is connected to the middle of the support portion 513, and the support surface is on the side of the support portion 513 away from the second connection portion 512.

[0045] In the embodiment of the present application, the first connecting portion 511 is used to connect the first telescopic member 52 and the second telescopic member 53. When the telescopic support mechanism 50 switches between the contracted state and the extended state, the first telescopic member 52 and the second telescopic member 53 switch between retracting the first connecting member and extending the first connecting member. When the telescopic support mechanism 50 is in the contracted state, the support portion 513 is located at a first position away from the bending portion 33, and provides a storage space for the bending portion 33 between the first shell 10 and the second shell 20 to prevent the bending portion 33 from being folded due to insufficient storage space. When the telescopic support mechanism 50 is in the extended state, the support portion 513 is located at a second position close to the bending portion 33, and provides a certain supporting force for the unfolded bending portion 33. The second connecting member is used to connect the first connecting member and the supporting portion 513. The first end of the second connecting portion 512 is connected to the middle of the first connecting portion 511, and the second end of the second connecting portion 512 is connected to the middle of the supporting portion 513, and the supporting surface is on the side of the supporting portion 513 away from the second connecting portion 512. When the first gear 4123 and the second gear mesh and rotate to realize the rotation of the first shell 10 and the second shell 20, the first sub-screen 31 and the second sub-screen 32 can be overlapped or separated. When the first sub-screen 31 and the second sub-screen 32 are overlapped, the first telescopic member 52 and the second telescopic member 53 are retracted into the first connecting member, and the support member 51 is away from the bending portion 33, providing a certain accommodation space for the bending portion 33. When the first sub-screen 31 and the second sub-screen 32 are separated and overlapped, the first telescopic member 52 and the second telescopic member 53 extend out of the first connecting member, and the support member 51 is away from the bending portion 33, providing a certain accommodation space for the bending portion 33.

[0046] It should be noted that the support member 51 has a certain extension length along the direction parallel to the first connecting member, and has the function of providing a certain storage space for the upper bending portion 33 in the direction parallel to the first connecting member.

[0047] Optionally, in the embodiment of the present application, the first rotating shaft assembly 41 further includes a first moving component 411 and a first driven component 413, the first moving component 411 is rotatably connected to the first rotating component 412, and the first moving component 411 can move along the first axis direction of the first rotating component 412;

[0048] The first movable component 411 has a wedge surface, and the distance from the wedge surface to the first axis gradually increases in the direction approaching the first gear 4123. The first driven component 413 is fixedly connected to the first shell 10 and abuts against the wedge surface. When the first movable component 411 moves relative to the first rotating component 412, the wedge surface drives the first driven component 413 to move and causes the bending portion 33 to extend and retract.

[0049] In the embodiment of the present application, the cooperation of the first rotating part 412, the first moving part 411 and the first driven part 413 can drive the first housing 10 to approach or move away from the first moving part 411, and the first housing 10 will also move away from the second housing 20, so as to straighten or relax the bent portion 33. Specifically, this can be achieved through the interaction between the wedge surface and the first driven part 413, and the first driven part 413 can be moved closer to or away from the first moving part 411 as a whole through different cooperation positions of the wedge surface and the first driven part 413. The principle is as follows: the rotation of the first rotating component 412 drives the first equivalent cam (the first movable component 411 is slidable along the first axis direction) to move linearly in the axial direction of the frame 43 (the rotation axis of the first rotating component 412), thereby driving the second equivalent cam (the wedge surface on the first movable component 411) to extend and retract in the radial direction of the frame 43, thereby realizing the extension and retraction of the first shell 10 during the folding process of the electronic device, solving the problem of insufficient or excessive screen size caused by different rotation radii during the external folding process of the flexible screen 30, and avoiding screen scratches and wrinkles.

[0050] It should be noted that the second rotating shaft assembly 42 has the same or similar structure as the first rotating shaft assembly 41 , and the two can form a structure similar to a hinge. The second rotating shaft assembly 42 also includes a corresponding second moving component and a second driven component.

[0051] Optionally, in the embodiment of the present application, the first rotating component 412 includes a first rod portion 4121 and a second rod portion 4122 that are fixedly connected, the first rod portion 4121 is parallel to the rotation axis of the first gear 4123, the second rod portion 4122 intersects with the rotation axis of the first gear 4123, and the first gear 4123 is located at the connection position between the first rod portion 4121 and the second rod portion 4122;

[0052] The second rotating component includes a third rod and a fourth rod that are fixedly connected. The third rod is parallel to the rotation axis of the second gear, and the fourth rod intersects the rotation axis of the second gear. The second gear is located at the connection position between the third rod and the fourth rod.

[0053] In the embodiment of the present application, the first rod 4121 is used to realize the rotation action, and can cooperate with the first gear 4123 to rotate. The second rod 4122 is used to connect the first housing 10, and can drive the first housing 10 to rotate relative to the first gear 4123. The corresponding first rod 4121 is set in a direction parallel to the rotation axis of the first gear 4123. The second rod 4122 intersects with the rotation axis of the first gear 4123. Specifically, the second rod 4122 and the first rod 4121 can be set perpendicular to each other. The second rotating component has the same structure and the same setting method as the first rotating component 412, which will not be repeated here.

[0054] Optionally, in the embodiment of the present application, the first moving component 411 includes a first sleeve 4111 and a wedge block 4112, the first sleeve 4111 is movably connected to the wedge block 4112, the wedge surface is on the wedge block 4112, and the wedge block 4112 is adapted to the first driven component 413;

[0055] The first rotating component 412 further includes a second sleeve 4124 connected to the first rod portion 4121 . The first sleeve 4111 is sleeved outside the second sleeve 4124 . The second sleeve 4124 moves relatively along a preset track through the guide assembly 414 .

[0056] In the embodiment of the present application, the cooperation of the first sleeve 4111 and the wedge block 4112 can form an equivalent cam, so that the first driven component 413 can move closer to or away from the first sleeve 4111. After the first sleeve 4111 is movably connected with the wedge block 4112, the wedge block 4112 can have a certain activity space, so that the cooperation between the wedge block 4112 and the first driven component 413 is more stable; the second sleeve 4124 is fixedly connected with the first rod 4121, and the guide assembly 414 at the connection between the second sleeve 4124 and the first sleeve 4111 can be another equivalent cam, so that during the relative movement of the second sleeve 4124 and the first sleeve 4111, the first sleeve 4111 can be moved relatively along a preset track through the guide assembly 414. The preset track here is a spiral track, that is, a moving track in which sliding and rotation are performed simultaneously.

[0057] Optionally, in the embodiment of the present application, the first driven component 413 includes a roller rod 4131 and a roller 4132, one end of the roller rod 4131 is connected to the first shell 10, the other end of the roller rod 4131 is rotationally connected to the roller 4132, and the roller 4132 is in contact with the wedge surface.

[0058] In the embodiment of the present application, the roller rod 4131 can be stably connected to the first shell 10, and the roller 4132 can reduce the sliding friction between the first driven component 413 and the wedge surface, reduce damage during the transmission process, and improve the bending accuracy of the shaft mechanism 40.

[0059] Optionally, in the embodiment of the present application, the guide assembly 414 includes a matching guide block 4141 and a guide groove 4142, one of which is disposed on the first sleeve 4111, and the other is disposed on the second sleeve 4124;

[0060] The guide groove 4142 includes a first guide groove 41421 and a second guide groove 41422 which are interconnected. When the electronic device switches from the unfolded state to the folded state so that the first sub-screen 31 and the second sub-screen 32 are parallel to and spaced apart from each other, the guide block 4141 moves along the first guide groove 41421, and the wedge block 4112 slides relative to the first follower component 413. When the electronic device switches from the unfolded state to the folded state so that the first sub-screen 31 and the second sub-screen 32 are parallel to and abut against each other, the guide block 4141 moves along the second guide groove 41422, and the wedge block 4112 and the roller 4132 are relatively stationary.

[0061] In the embodiment of the present application, the coordinated setting of the guide block 4141 and the guide groove 4142 can realize the relative movement of the first sleeve 4111 and the second sleeve 4124. The setting of the first guide groove 41421 can realize the above-mentioned preset trajectory. In the process of switching between the unfolded state and the first folded position, the guide block 4141 moves along the first guide groove 41421, and the wedge block 4112 and the first driven component 413 slide relative to each other; the setting of the second guide groove 41422 can realize the relative rotation of the first sleeve 4111 and the second sleeve 4124. In the process of switching between the unfolded state and the second folded position, the guide block 4141 moves along the second guide groove 41422, and the wedge block 4112 and the first driven component 413 are relatively stationary.

[0062] It should be noted that the first guide groove 41421 is a groove-like structure that is approximately a spiral line, and the bottom of the first guide groove 41421 can be through or a solid groove bottom. The second guide groove 41422 is a circular arc groove-like structure surrounding the axis of rotation. The head end of the second guide groove 41422 is connected to the tail end of the first guide groove 41421. The working principle and assembly process of the rotating shaft mechanism 40 in the present application are as follows:

[0063] First, put one end of the first sleeve 4111 on the first rotating component 412, screw the guide block 4141 into the hole at one end of the first sleeve 4111, so that the guide block 4141 can slide in the groove of the first rotating component 412, and there is gear meshing between the first rotating component 412 and the second rotating component, mainly to achieve that both sides can be flipped at the same time when folded, insert the frame 43 into the hole of the first rotating component 412, which can be regarded as a rotating pair here, put the other end of the first sleeve 4111 on the frame 43, and limit the movement of the first sleeve 4111 by the protruding guide rail on the frame 43, install the wedge block 4112 in the guide groove 4142 of the first sleeve 4111, so that the wedge block 4112 can rotate around the axis of the first sleeve 4111, which can be regarded as a sliding pair here, and install the telescopic support mechanism 50 on the first rotating component 412 in a hinged form, so that it can be telescoped and lifted with the rotation of the first rotating component 412.

[0064] Then, install the roller 4132 on the roller rod 4131 on the corresponding shell and fix it by a fixing pin so that the roller 4132 is in rolling contact with the wedge block 4112, and insert the first rotating component 412 into the fixed guide rail of the shell, which can be regarded as a sliding pair here. The corresponding shell is connected to the first rotating component 412 through a spring module to realize the integration of the frame 43 and the shell (including the first shell 10 and the second shell 20), while ensuring that the roller 4132 can always be in contact with the wedge block 4112.

[0065] When the electronic device is in the unfolded state, the first rotating component 412 rotates synchronously under the gear meshing, driving the guide block 4141 to slide in the groove of the first rotating component 412, thereby driving the first sleeve 4111 to slide inward along the axial direction of the frame 43. At this time, the wedge block 4112 also slides inward, thereby pushing out the shell. At the same time, the wedge block 4112 and the driven component rotate to both sides, realizing the outward sliding of the shell during the unfolding process, and the flexible screen 30 is adhered to the shell, thereby realizing the flattening of the flexible screen 30 and avoiding the occurrence of wrinkles. At the same time, the telescopic support mechanism 50 is in a supporting state, providing support for the screen.

[0066] When the electronic device is in a folded state, and the first sub-screen 31 and the second sub-screen 32 are separated and overlapped, the flexible screen 30 is turned outward. The first rotating component 412 rotates synchronously under the meshing of the gears, driving the guide block 4141 to slide in the oblique groove of the first rotating component 412, thereby driving the sleeve to slide outward along the axial direction of the frame 43, and the wedge block 4112 also slides outward. Under the action of the spring module, the roller 4132 keeps constant contact with the wedge block 4112. At this time, the roller 4132 rolls along the wedge block 4112, and the wedge block 4112 and the roller 4132 rotate inwardly. The shell is pulled back inward by the spring module, realizing the inward sliding of the shell during the closing process, avoiding the flexible screen 30 from being damaged during the folding process, and realizing the folding of the flexible screen 30. At the same time, the telescopic support mechanism 50 is driven by the first rotating component 412 to extend horizontally and contract longitudinally, avoiding the interference between the telescopic support mechanism 50 and the screen.

[0067] When the electronic device is in a folded state, and the first sub-screen 31 and the second sub-screen 32 are in contact and overlapped, the flexible screen 30 is folded inward. The first rotating component 412 rotates synchronously under the meshing of the gears, driving the guide block 4141 to slide in the horizontal groove of the first rotating component 412. At this time, the first sleeve 4111 does not move, and the wedge block 4112 and the driven component rotate inward. Since the first sleeve 4111 does not move, the wedge block 4112 and the roller 4132 remain relatively still, so the frame 43 does not move. At this time, only the storage problem of the flexible screen 30 during the inward folding needs to be considered. Under the action of the first rotating component 412, the telescopic support mechanism 50 shrinks in the horizontal direction and the longitudinal direction, realizing the storage of the flexible screen 30, solving the folding problem caused by insufficient storage space during the inward folding of the flexible screen 30, and realizing the inward folding of the hinge mechanism 40.

[0068] The present application drives the lateral extension and retraction of the telescopic support mechanism 50 through the rotation of the first rotating component 412, thereby driving the telescopic support mechanism 50 to rise and fall, thereby solving the folding problem caused by insufficient storage space during the internal folding of the flexible screen 30. At the same time, when the mobile terminal is flattened, sufficient support is given to the flexible screen 30, thereby realizing the internal folding of the mobile terminal.

[0069] In the present application, the rotation of the first rotating component 412 drives the first equivalent cam to move linearly in the axial direction of the frame 43, thereby driving the second equivalent cam to extend and retract in the radial direction of the frame 43, thereby realizing the extension and retraction of the shell during the folding process of the smart terminal, solving the problem of insufficient or excessive screen size caused by different rotation radii during the external folding process of the flexible screen 30, avoiding screen scratches and wrinkles, and realizing the external folding of the mobile terminal.

[0070] The pivot mechanism 40 of the present application is of a splicing type, that is, the first rotating component 412 and the frame 43 are not of an integrated design. When the folding structure is mechanically damaged, the damaged parts can be disassembled and replaced for repair, and there is no need to repair the entire pivot mechanism 40, thereby reducing the user's after-sales repair costs. At the same time, due to the splicing design, when designing specific parts, the structure and materials of each part can be optimized, which is conducive to reducing the weight of the overall mechanism.

[0071] The first rotating component 412 used in the present application is gear meshing, which can apply a certain damping to enable the folding screen to stop at any angle.

[0072] The hinge mechanism 40 of the present application can be applied to mobile phones, laptop computers, tablet computers, e-books, etc., and can also be other mobile terminals. The solution of using two equivalent cam mechanisms to realize the unilateral and bilateral contraction movement of the external folding screen, the solution of using the telescopic support mechanism 50 to solve the storage problem of the flexible screen 30 to realize the inward folding, and the solution of realizing the inward and outward folding by the above two solutions at the same time should all be within the scope of protection of the present invention.
