If the folding supporting piece is dislocated under impact force, the folding supporting piece can only be abutted against the abutting part when the folding supporting piece is dislocated, and the mutual abutting relationship between the folding supporting piece and the abutting part effectively prevents the dislocation amount of the folding supporting piece, so that the structural position of the whole rotating shaft mechanism under the impact is not easy to change, the structural stability is relatively high, and the damage to the foldable screen under the impact is effectively reduced.

Referring to fig. 1, an electronic device 500 is provided in the present embodiment, where the electronic device 500 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The electronic device 500 of the present embodiment is described by taking a mobile phone as an example.

Referring to fig. 1 and fig. 2, the electronic device 500 includes an electronic component 400, a housing component 300, a foldable screen 200 and a hinge mechanism 100, wherein the electronic component 400 and the hinge mechanism 100 are disposed in the housing component 300, and the foldable screen 200 is disposed on the housing component 300 and the hinge mechanism 100. The housing assembly 300 and the foldable screen 200 can be folded or unfolded through the hinge mechanism 100, and when the housing assembly 300 and the foldable screen 200 are folded, the volume of the electronic device 500 is relatively small, which is convenient for storage and carrying.

The housing assembly 300 includes a first housing 303 and a second housing 305, and the first housing 303 and the second housing 305 are respectively connected to both sides of the rotation shaft mechanism 100. The second housing 305 is foldable or unfoldable with respect to the first housing 303. The housing assembly 300 is used to carry the foldable screen 200 while providing protection to the electronics assembly 400. The first case 303 and the second case 305 support both ends of the foldable screen 200, respectively. The hinge mechanism 100 can be folded or unfolded and supports a portion of the foldable screen 200 between both ends. In one embodiment, the first housing 303 may be a hard housing, and the second housing 305 may also be a hard housing. The first case 303 and the second case 305 may stably support both ends of the flexible display 201.

The hinge mechanism 100 is deformable as the second housing 305 is folded or unfolded with respect to the first housing 303, and restricts the second housing 305 from being detached from the first housing 303, and the hinge mechanism 100 is also used to support the foldable screen 200 to prevent the foldable screen 200 from collapsing. Opposite two side edges of the rotating shaft mechanism 100 are respectively connected to the first housing 303 and the second housing 305. The rotation shaft mechanism 100 utilizes its own rotation characteristic to enable the first housing 303 to be turned over relative to the second housing 305, such that the first housing 303 is folded, or angled, or unfolded, or flattened relative to the second housing 305.

Referring to fig. 3, the hinge mechanism 100 includes a base 10 and a rotating element 30 rotatably connected to each other, the rotating element 30 is connected to a housing element 300, and a first housing 303 and a second housing 305 of the housing element 300 are rotated by the relative rotation between the base 10 and the rotating element 30.

In this embodiment, there are two rotating assemblies 30, the two rotating assemblies 30 are respectively disposed on two opposite sides of the base 10, and the two rotating assemblies 30 are respectively connected to the first housing 303 and the second housing 305. In other embodiments, the rotating assembly 30 may be one, with one of the first housing 303 and the second housing 305 being attached to the base 10 and the other being attached to the rotating assembly 30. The embodiment of the present disclosure is described by taking two rotating assemblies 30 as an example. In the present embodiment, the two rotation assemblies 30 are disposed substantially symmetrically with respect to the base 10, so that the rotation states of the housing assembly 300 and the foldable screen 200 based on the rotation of the rotation assemblies 30 can be substantially symmetrical, and the housing assembly can have a symmetrical structure in the folded state, and the housing volume is relatively small.

Referring to fig. 4, in the present embodiment, the base 10 includes a base 12 and a rotating shaft housing 14 stacked on the base 12, and the base 12 forms a structure rotatably connected to the rotating assembly 30 to facilitate the installation of the rotating shaft mechanism 100. In this embodiment, the holder body 12 may be provided with a rotation shaft hole 121, and the rotation shaft hole 121 is used for inserting a rotation shaft to realize the rotatable connection between the holder body 12 and the rotating assembly 30. Further, the number of the rotating shaft holes 121 may be two, two rotating shaft holes 121 are disposed at intervals, and each rotating shaft hole 121 is used for accommodating one rotating shaft and is connected with one corresponding rotating assembly 30. The rotation shaft hole 121 defines a rotation axis O, so that the rotation assembly 30 can rotate about the rotation axis O.

The spindle housing 14 is configured to receive the housing 12 to provide integral protection for the spindle mechanism 100 and to form a modular assembly solution that facilitates transportation and assembly. Specifically, the shaft housing 14 is provided with a receiving cavity 141, and the seat 12 is disposed in the receiving cavity 141 and can be fixed to the shaft housing by a fastening member such as a screw. Further, the rotating shaft housing 14 may also be a housing component of the electronic device 500, and together with the first housing 303 and the second housing 305, the housing component forms an appearance surface of the electronic device 500, and in this case, the first housing 303 and the second housing 350 are respectively disposed on two opposite sides of the rotating shaft housing 14.

The rotating assembly 30 includes a frame 32, a link 34 and an overlapping support 36, the frame 32 is spaced apart from the base 10, the link 34 is movably disposed between the frame 32 and the base 10, and the overlapping support 36 is rotatably connected to the frame 32 and slidably engaged with the link 34. When the base 10 and the rotating assembly 30 rotate relatively, the linkage member 34 drives the folding support member 36 to rotate based on the sliding fit structure, so that the folding support member 36 can rotate to present a certain inclination angle when the rotating shaft mechanism 100 is folded, so as to provide a certain accommodating space for bending the foldable screen 200, thereby preventing the rotating shaft mechanism 100 from pushing the foldable screen 200 to cause the foldable screen 200 to generate the arching phenomenon.

In this embodiment, the bracket 32 is connected to the first housing 303, for example, the bracket 32 can be fixed in the first housing 303 by a fastener such as a screw, and the bracket 32 is located between the foldable screen 200 and the first housing 303. Referring to fig. 5, the bracket 32 is provided with a guiding groove 321, and the guiding groove 321 is used for accommodating a part of the structure of the link 34, so that the link 34 can be slidably connected with the bracket 32. In the present embodiment, the guide groove 321 has a substantially straight groove structure, and the extending direction of the guide groove 321 is substantially perpendicular to the rotation axis O.

Referring to fig. 6, the linkage 34 includes a body 341 and a driving portion 343 disposed on the body 341, wherein one end of the body 341 is rotatably connected to the base 10, and the other end is slidably connected to the bracket 32. Further, in the present embodiment, the main body 341 includes a rotating portion 3411, a sliding portion 3413, and a stopper portion 3415, and the stopper portion 3415 is connected between the rotating portion 3411 and the sliding portion 3413.

The rotating portion 3411 is rotatably connected to the base 10, for example, the rotating portion 3411 is rotatably connected to the seat 12 of the base 10 through a first pivot 3412. The structure of the first pivot 3412 is not limited, and may be a substantially shaft-like structure directly formed on the rotating part 3411, or a structure such as a rotating shaft and a pin shaft independent of the rotating part 3411.

The sliding portion 3413 is substantially a flat plate structure, and one side of the sliding portion 3413 is provided with a sliding protrusion 3414 (see fig. 5), the sliding protrusion 3414 is slidably received in the guiding slot 321 of the bracket 32, and when the base 10 drives the link 30 to rotate, the sliding protrusion 3414 can slide in the guiding slot 321, so as to avoid structural interference during the rotation process, and thus the rotation of the rotating shaft structure 100 is relatively smooth. In other embodiments, the structure between the sliding part 3413 and the guiding groove 321 may be replaced by other guiding structures, for example, the bracket 32 may be provided with a guiding groove, a guiding hole, etc., and the sliding part 3413 or/and the sliding protrusion 3414 may be slidably engaged with the guiding groove, the guiding hole, etc.; alternatively, the sliding portion 3413 and/or the sliding protrusion 3414 may be slidably engaged with the bracket 32 through a guide rail and a guide groove.

In the present embodiment, the avoiding portion 3415 is bent with respect to the sliding portion 3413 to form an accommodating space 3416 for accommodating the overlapping support 36 together with the sliding portion 3413. When the link 34 rotates the folding support 36 relative to the frame 32, the folding support 36 tilts relative to the link 34, and the receiving space 3416 provides enough space for the tilted folding support 36 to move, so as to avoid interference of the movement of the folding support 36 by physical structures, and to make the overall structure of the hinge mechanism 100 more compact.

The driving portion 343 is connected to the sliding portion 3413, and the driving portion 343 is configured to drive the folding support 36 to move. Further, in the present embodiment, the driving portion 343 has a substantially columnar shape, and is connected to one end of the sliding portion 3413. In the embodiment, the driving portion 343 may also have another rotating shaft or arc-shaped sliding groove structure, and the description is not limited herein.

Further, in the present embodiment, the linkage 34 further includes an abutting portion 345, and the abutting portion 345 is connected to the body 341 and protrudes relative to the body 341. The abutment 345 serves to limit the structural displacement of the folding support 36 to ensure the structural stability of the rotating assembly 30. Further, an abutting portion 345 is connected to a side of the body 341 facing the folding support 36, and the abutting portion 345 may be a convex structure and protrudes relative to a surface of the body 341. In the present embodiment, the abutting portion 345 is disposed at the connection position of the avoiding portion 3415 and the sliding portion 3413, that is, at the bent portion of the main body 341. The abutment 345 may include an abutment surface 3451, the abutment surface 3451 being located on a side of the abutment 345 facing away from the turning portion 3411. The abutment surface 3451 may be a flat surface, which may be substantially parallel to the rotation axis O and substantially perpendicular to the sliding portion 3413. By setting the position and angle of the abutting surface 3451, the structural displacement of the folding support 36 can be effectively limited to ensure the structural stability of the rotating assembly 30.

Referring to fig. 6 and 7, the folding support 36 is disposed on a side of the support frame 32 facing the foldable screen 200. The folding support 36 is rotatably connected to the support 32, for example, the folding support 36 may be rotatably connected to the support 32 through a rotating shaft or the like, or the folding support 36 may be rotatably connected to the support 32 through an arc chute and an arc slider cooperating with the rotating structure, as shown in fig. 7, an arc slider may be disposed on the support 32, an arc chute may be disposed on the folding support 36, and the arc slider may be slidably received in the arc chute, which is beneficial to the disassembly and assembly of the rotating connection structure between the folding support 36 and the support 32.

Referring to fig. 8, in the present embodiment, the folding supporting member 36 is provided with a sliding groove 361, and the sliding groove 361 is configured to be slidably engaged with the driving portion 343. Further, the driving portion 343 is at least partially received in the sliding groove 361, and when the base 10 and the rotating assembly 30 rotate relatively, the driving portion 343 slides in the sliding groove 361 to rotate and tilt the folding supporting member 36 relative to the gap 32.

Further, the folding support 36 includes a connection portion 363 and a guide portion 365.

In this embodiment, the connecting portion 363 is substantially plate-shaped, is disposed on a side of the bracket 32 facing the foldable screen 200, and is rotatably connected to the bracket 32. The connection 363 may also serve to support the foldable screen 200 to prevent the foldable screen 200 from collapsing in the unfolded state. Further, through the rotating and sliding connection relationship between the folding support 36, the linkage 34, the bracket 32 and the base 10, the hinge mechanism 100 can be directly disposed on the non-display side (i.e., the back side) of the foldable screen 200 and can support the foldable screen 200, so as to prevent the hinge mechanism 100 from being disposed on the peripheral edge of the foldable screen 200 and occupying the frame space of the electronic device 500, which is beneficial to realizing a larger screen occupation ratio. In some embodiments, a side of the connection portion 363 away from the bracket 32 may be further fixedly connected (e.g., adhered) to the foldable screen 200, so that when the connection portion 363 rotates and tilts, the foldable screen 200 can be driven to bend toward the direction of the rotating shaft mechanism 100, and a guiding effect is formed on the bent state of the foldable screen 200, so that the foldable screen 200 bends and deforms toward a predetermined direction in the folded state, so as to avoid abnormal arching or bending deformation of the foldable screen 200 during folding.

In this embodiment, the connecting portion 363 includes a first side 3631 and a second side 3633 opposite to each other, the first side 3631 is rotatably connected to the bracket 32, the second side 3633 is located on a side of the connecting portion 363 close to the base 10, and the second side 3633 is opposite to or abutted against the abutting surface 3451. Here, the first side 3631 and the second side 3633 can be both understood as a side portion of the connecting portion 363 near an edge thereof, and can also be understood as an edge end portion of the connecting portion 363.

Referring to fig. 9 to 12, in the process of rotating the rotating assembly 30, since the first side 3631 is rotatably connected to the bracket 32, when the linkage 34 drives the folding support 36 to rotate relative to the bracket 32, the second side 3633 of the folding support 36 slides relative to the avoiding portion 3415 until the base 10 and the rotating assembly 30 are folded, the second side 3633 is opposite to the abutting portion 345, and the abutting portion 345 and the folding support 36 are constrained with each other in position, so as to maintain the stability of the surrounding structure of the avoiding space 3416. When the hinge mechanism 100 is impacted by an external force in the folded state (e.g., the electronic device 500 falls in the folded state), the abutting portion 345 and the second side 3633 of the folding support 36 are in a restraining relationship to limit the displacement of the folding support 36 under the impact, for example, when the avoiding space 3416 is formed, the folding support 36 is substantially inclined with respect to the base 10 while being connected to the housing of the electronic device 500, the link 34 where the abutting portion 345 is located is connected to the base 10, and the folding support 36 substantially forms one inclined side of the triangular structure, which has high structural stability. If the folding support 36 is dislocated under the impact force, it can only abut against the abutting surface 3451 of the abutting portion 345 during the dislocation, and the abutting relationship therebetween effectively prevents the dislocation amount of the folding support 36, so that the structural position of the entire rotating shaft mechanism 100 under the impact is not easily changed, and the structural stability is relatively high.

In the present embodiment, the guiding portion 365 is disposed between the connecting portion 363 and the linkage 34, and the sliding groove 361 is opened in the guiding portion 365 to allow the guiding portion 365 to be slidably engaged with the driving portion 343 of the linkage 34. Further, the guiding portion 365 is connected to a side of the connecting portion 363 facing the bracket 32 and protrudes relative to a surface of the connecting portion 363, and the driving portion 343 is disposed through the sliding slot 361, so that the matching structure between the folding supporting member 36 and the linking member 34 is more compact.

In this embodiment, the sliding groove 361 of the guiding portion 365 is substantially a groove inclined with respect to the connecting portion 363. Chute 361 has opposite first and second ends 3611, 3613, with first end 3611 adjacent base 10 and second end 3613 remote from base 10. The first end 3611 and the second end 3613 jointly define an extending direction of the sliding groove 361, that is, the extending direction of the sliding groove 361 may be understood as a direction pointing from the first end 3611 to the second end 3613, or may be understood as a direction pointing from the second end 3613 to the first end 3611. The sliding grooves 361 and the guide grooves 321 extend in substantially the same direction, and both extend toward the base 10 from the holder 32. Further, the extending direction of the sliding groove 361 is substantially inclined with respect to the connecting portion 363, so that when the driving portion 343 slides in the sliding groove 361, it can slide between the first end 3611 and the second end 3613 to drive the connecting portion 363 to rotate and incline.

Further, according to the inclined structure of the sliding groove 361, the distance between the first end 3611 and the connecting portion 363 is smaller than the distance between the second end 3613 and the connecting portion 363, so that when the rotating shaft mechanism 100 is folded, the link 34 rotates relative to the base 10 and moves in a direction away from the bracket 32, and the driving portion 343 slides from the second end 3613 to the first end 3611, thereby driving the folding support 36 to rotate and incline relative to the bracket 32.

Referring to fig. 13 and 14, in some embodiments, the rotating shaft mechanism 100 may further include a flat supporting member 38 and a rotating member 39, the flat supporting member 38 is disposed at a distance from the base 10, and the rotating member 39 is disposed between the flat supporting member 38 and the base 10. Further, the flattened support 38 is fixedly disposed relative to the bracket 32, e.g., both the flattened support 38 and the bracket 32 are fixedly coupled to the same centering assembly, such that they remain relatively stationary during operation. The rotating member 39 is rotatably connected to the base 10 and slidably engaged with the flat supporting member 38, and when the rotating assembly 30 rotates relative to the base 10, the flat supporting member 38 can slide relative to the rotating member 39. When the rotating assembly 30 and the base 10 are in the flat state, one end of the flat supporting part 38 abuts against the surface of the rotating part 39, so that the positional relationship between the rotating part 39 and the flat supporting part 38 is restricted, and the structural stability of the rotating shaft mechanism 100 can be maintained. If the rotating shaft mechanism 100 is impacted by an external force in the flat state (for example, the electronic device 500 falls in the flat state), the displacement of the flat supporting member 38 under impact is limited due to the structural constraint relationship formed between the rotating member 39 and the flat supporting member 38, and the mutual abutting relationship between the rotating member 39 and the flat supporting member 38 effectively prevents the displacement of the overlapped supporting member 36, so that the structural position of the rotating shaft mechanism 100 under impact is not easily changed, and the structural stability is relatively high.

In this embodiment, the hinge mechanism 100 may further include a middle frame 50, and the middle frame 50 may be used for supporting the foldable screen 200 and for fixedly mounting the bracket 32 and the flat supporting member 38, so that the bracket 32 and the flat supporting member 38 are both relatively fixedly disposed on the middle frame 50, and the rotation of the bracket 32 and the flat supporting member 38 relative to the base 10 may be controlled as long as an external force is applied to the middle frame 50. Further, the middle frame 50 may be provided with a receiving groove 52, and the receiving groove 52 is used for receiving the bracket 32 and the flattening support 38, so that the structure of the rotating shaft mechanism 100 is more compact, and the thin design of the electronic device 500 is facilitated.

Referring to fig. 15, the flat supporting member 38 is provided with a guiding groove 381, and the guiding groove 381 is used for sliding fit with the rotating member 39. The guide slot 381 is a generally straight slot configuration disposed generally perpendicular to the axis of rotation O to permit movement of the flattened support member 38 relative to the rotational member 39 in the direction defined by the guide slot 381.

The rotating member 39 includes a main body 391 and a stopper 393, wherein one end of the main body 391 is rotatably connected to the base 10, and the other end is slidably engaged with the guide slot 381. The limiting part 393 is connected to the main body 391 and protrudes from the main body 391, when the base 10 and the rotating assembly 30 rotate relatively, the flattening support 38 slides relative to the main body 391, and when the base 10 and the rotating assembly 30 are in a flattening state, one end of the flattening support 38 contacts with the limiting part 393, so that the position of the flattening support 38 relative to the main body 391 is limited.

Referring to fig. 16 and 17, in the present embodiment, the main body 391 includes a rotating shaft portion 3911, a transition portion 3913 and a guiding portion 3915, and the transition portion 3913 is connected between the rotating shaft portion 3911 and the guiding portion 3915.

The rotating shaft portion 3911 is disposed in the receiving cavity 141 of the base 10 and rotatably connected to the base 10. The rotating shaft portion 3911 may be connected to the seat body 12 by a rotating shaft or the like, and a rotation axis of the rotating shaft portion 3911 is disposed substantially coaxially with the rotation axis O of the link 34, so that the rotating member 39 can rotate synchronously with the link 34. The transition portion 3913 is substantially plate-shaped and is bent with respect to the rotation shaft portion 3911.

The guide portion 3915 is substantially a rod-shaped structure, which is substantially perpendicular to the transition portion 3913 and is movably received in the guide slot 381 for guiding the moving direction of the flattening support 38. When the base 10 and the rotating assembly 30 are in the flat state, the guiding portion 3915 is disposed in a direction substantially parallel to the plane of the outer surface of the rotating shaft housing 14 of the base 10, so as to ensure that the rotating member 39 and the flat supporting member 38 can effectively support the display screen 200 in the flat state. Further, in the present embodiment, the rotation shaft housing 14 may include an outer wall portion 143 and a side wall portion 145, and the side wall portion 145 is connected to the outer wall portion 143 and is bent with respect to the outer wall portion 143. The number of the side wall portions 145 may be two, the two side wall portions 145 are respectively connected to two opposite sides of the outer wall portion 143, and the two side wall portions 145 are disposed substantially in parallel with each other. The side wall portion 145 and the outer wall portion 143 together form the housing chamber 141. When the base 10 and the pivot assembly 30 are in the flattened state, the transition portion 3913 is spaced apart from the sidewall portion 145 (e.g., they are disposed in parallel), and the guide portion 3915 extends parallel to the plane of the outer wall portion 1415.

Further, the stopper 393 is provided at a side of the guide portion 3915 close to the base 10 and protrudes with respect to the guide portion 3915, and when the relative position between the guide portion 3915 and the guide groove 381 reaches a limit state, the end of the flat supporting member 38 is in contact with the stopper 393, so that the flat supporting member 38 cannot move any more with respect to the rotating member 39, thereby functioning to restrict the movable position of the flat supporting member 38.

In this embodiment, the flat supporting member 38 can slide relative to the rotating member 39 when the rotating assembly 30 rotates relative to the base 10. When the rotating assembly 30 and the base 10 are in the flat state, one end of the flat supporting member 38 abuts against the limiting portion 393, so that the positional relationship between the rotating member 39 and the flat supporting member 38 is restricted, and the structural stability of the rotating shaft mechanism 100 can be maintained. If the rotating shaft mechanism 100 is impacted by an external force in the flat state (for example, the electronic device 500 falls in the flat state), the displacement of the flat supporting member 38 under impact is limited due to the structural constraint relationship formed between the rotating member 39 and the flat supporting member 38, and the mutual abutting relationship between the rotating member 39 and the flat supporting member 38 effectively prevents the displacement of the overlapped supporting member 36, so that the structural position of the rotating shaft mechanism 100 under impact is not easily changed, and the structural stability is relatively high.

In the above embodiments of the present application, the linkage 34 and the rotor 39 are separately provided, but it should be understood that in other embodiments, the linkage 34 and the rotor 39 may be integrally formed. For example, in some embodiments, the structure of the link 34, such as the structure of the body 341, the structure of the driving portion 343, the structure of the abutting portion 345, and the like, may be formed on the rotation member 39, and specifically, for example, the abutting portion 345, the driving portion 343 of the link 34 may be directly disposed on the main body 9391 of the rotation member 39. In other embodiments, the structures of the rotating element 39, such as the structure of the main body 391 and the structure of the limiting portion 393, may be directly disposed on the main body 341 of the linking element 34, and are not described in detail herein.

Referring to fig. 18, fig. 18 is a schematic structural diagram of the hinge mechanism 100, which shows a general structure of the hinge mechanism 100 and the housing assembly 300 by a modular drawing method, and is not intended to limit the structure of the electronic device 500 according to the embodiment of the present disclosure. In this embodiment, one rotating shaft mechanism 100 may include two rotating assemblies 30, and the two rotating assemblies 30 may include a first rotating assembly 3001 and a second rotating assembly 3003, where the first rotating assembly 3001 and the second rotating assembly 3003 are respectively disposed on two opposite sides of the base 10 and are substantially symmetrically disposed with respect to the base 10. The first rotating member 3001 is connected to the first housing 303, and the second rotating member 3003 is connected to the second housing 305. The first rotating component 3001 and the second rotating component 3003 can rotate relative to the base 10 under the action of external force to approach each other to form a folded state, or move away from each other to form an unfolded state, so that the first housing 303 and the second housing 305 can be folded or unfolded relatively smoothly, and the volume when folded is relatively small. The electronic device 500 may include a plurality of hinge mechanisms 100, and the hinge mechanisms 100 are sequentially arranged along the direction of the rotation axis O and connected to the first housing 303 and the second housing 305, so that the rotation of the electronic device 500 is balanced and stable.

In other embodiments, one hinge mechanism 100 may include only one rotating component 30, and two hinge mechanisms 100 are used to realize the rotating connection between the first housing 303 and the second housing 305 when assembled to the housing component 300 of the electronic device 100. For example, the rotary shaft assembly 30 of one of the rotary shaft mechanisms 100 is connected to the first housing 303, the base 10 is connected to the second housing 305, and the rotary shaft assembly 30 of the other rotary shaft mechanism 100 is connected to the second housing 305. Of course, the number of the hinge mechanisms 100 may be multiple, for example, four, six, eight, etc., so that the rotation of the electronic apparatus 500 is balanced and stable.

Referring to fig. 2 again, the electronic assembly 400 includes a first electronic module 401, a second electronic module 403 and a flexible circuit board 405, the first electronic module 401 is disposed in the first housing 303, the second electronic module 403 is disposed in the second housing 305, and the flexible circuit board 405 is electrically connected to the first electronic module 401 and the second electronic module 403. Further, the first electronic module 401 may be a motherboard, a central processing unit provided with the motherboard, a memory, an antenna, a camera, a handset, and the like. The second electronic module 403 may also be composed of a printed circuit board and a functional module disposed on the printed circuit board, the second electronic module 403 is different from the first electronic module 401, and the second electronic module 403 may be a battery, a connector, a fingerprint module, etc.

The foldable screen 200 is laid on the first housing 303, the rotation shaft mechanism 100, and the second housing 305 in this order. In this embodiment, the foldable screen 200 comprises a flexible display screen 201. The flexible display 201 is folded or unfolded when the first housing 303 and the second housing 305 are turned over. The flexible display 201 is electrically connected to the electronic assembly 400 so that the electronic assembly 400 can control the operation of the flexible display 201.

In the electronic device and the rotating shaft mechanism thereof provided by the embodiment of the application, when the foldable screen is arranged on the shell assembly and the rotating shaft mechanism, the first shell and the second shell can rotate by means of the relative rotation between the base and the rotating component, at the moment, the driving part slides in the sliding groove to drive the overlapped supporting piece to rotate relative to the bracket, the overlapped supporting piece deflects to form a certain avoiding space when rotating, the avoiding space enables the rotating shaft mechanism to avoid forming abutting pressure or supporting force on the back of the foldable screen, and provides space to accommodate the bent structure of the foldable screen when folded (as shown in figure 12), therefore, the tendency of the folding screen to generate the arch deformation deviating from the rotating shaft mechanism can be avoided, namely, under the condition that the folding screen is arched without external force support, in the natural bending state, the foldable screen can be concavely deformed towards the rotating shaft mechanism, so that the foldable screen is prevented from being deformed without conforming to the bending tendency of the foldable screen. Therefore, the rotating shaft mechanism can protect the foldable screen when the foldable screen is folded, avoids the damage of the foldable screen caused by the irregular deformation of folding, and prolongs the service life of the foldable screen.

Further, the connecting portion may also serve to support the foldable screen to prevent the foldable screen from collapsing in the unfolded state. Through rotation, the sliding connection relation between coincide support piece, linkage, support and the base, can make pivot mechanism directly set up in the non-display side (also the back) of collapsible screen and can support collapsible screen, avoid pivot mechanism to set up and occupy electronic equipment's frame space at collapsible screen's edge all around, be favorable to realizing that bigger screen accounts for than.

Further, when the base and the rotating assembly are folded, the second side is opposite to the abutting part, and the abutting part and the overlapped supporting part are mutually restricted in position relation, so that the stability of the surrounding structure of the avoiding space can be maintained. If the rotating shaft mechanism is impacted by external force in the folding state (for example, the electronic device falls in the folding state), the limit relationship formed by the opposite second sides of the abutting part and the folding supporting part limits the displacement of the folding supporting part under the impact, for example, when an avoiding space is formed, the folding supporting part is approximately inclined relative to the base while being connected with the shell, the linkage part where the abutting part is located is connected with the base, the folding supporting part approximately forms one inclined edge in a triangular structure, and the structural stability of the folding supporting part is high. If the superposed supporting piece is dislocated under impact force, the superposed supporting piece can only be abutted with the abutting part during the dislocating, and the mutual abutting relationship between the superposed supporting piece and the abutting part effectively prevents the dislocation amount of the superposed supporting piece, so that the structural position of the whole rotating shaft mechanism under the impact is not easy to change, the structural stability is relatively high, and the damage to the foldable screen under the impact can be effectively reduced.

In the embodiment of the present application, the electronic device 500 may be a multi-purpose mobile phone that implements a small screen display, a large screen display, or a bent screen display, and exhibits multiple use functions. For example: when the electronic device 500 is folded on the flexible display screen 201, the first housing 303 and the second housing 305 can be folded together, and the electronic device 500 can be used as a mobile phone, so that the mobile phone is convenient for a user to carry and occupies a small space. When the flexible display screen 201 of the electronic device 500 is bent at a certain angle, the first housing 303 is unfolded relative to the second housing 305 and forms a certain angle with each other, and the electronic device 500 can be used as a notebook computer. When the electronic device 500 is in the unfolded state on the flexible display screen 201, the first housing 303 is unfolded relative to the second housing 305 and is flush with each other, and the electronic device 500 can be used as a tablet computer to increase the display area, obtain more display contents, and improve the user experience. Of course, the electronic device 500 may also be a multi-purpose tablet computer, a multi-purpose notebook computer, or other multi-function electronic devices with multiple mode switching functions.

Referring to fig. 19, in the present embodiment, the flexible display 201 includes a first display portion 202 attached to a first housing 303, a second display portion 203 attached to a second housing 305, and a bending display portion 204 connected between the first display portion 202 and the second display portion 203. The first display portion 202 and the second display portion 203 are folded or unfolded relatively with the first housing 303 and the second housing 305, respectively. The bending display portion 203 bends or expands as the first display portion 202 folds or expands relative to the second display portion 203. In some embodiments, the first display portion 202, the second display portion 203 and the bending display portion 204 may be an integrated structure, so that the flexible display 201 is a one-piece flexible display; alternatively, in some other embodiments, the bending display portion 204 is a flexible portion that can be bent, and the first display portion 202 and the second display portion 203 can be non-flexible portions, and the first display portion 202 and the second display portion 203 are folded or unfolded relatively by the bending display portion 204.
