The electronic device provided in the embodiments of the present application is described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1 to 17, an embodiment of the present application discloses an electronic device, which includes a display screen 100, a housing 200, and a folding mechanism 300.

The housing 200 includes a first supporting component 210 and a second supporting component 220, and both the first supporting component 210 and the second supporting component 220 can be formed by a hard material such as metal or plastic to ensure that both can provide stable supporting function for different parts in the display screen 100, in detail, the display screen 100 includes a first portion 110 and a second portion 120, the first portion 110 is supported by the first supporting component 210, and the second portion 120 is supported by the second supporting component 220. Optionally, the shapes and sizes of the first portion 110 and the second portion 120 may be the same, or the shapes and/or sizes of the first portion 110 and the second portion 120 may be different, so that the application range of the electronic device disclosed in the embodiment of the present application is relatively wider.

Moreover, the display screen 100 is a flexible and retractable structure, that is, the display screen 100 has a deformation capability, and meanwhile, the first supporting component 210 and the second supporting component 220 are connected by the folding mechanism 300, so that under the action of the folding mechanism 300, the first supporting component 210 and the second supporting component 220 can rotate relatively, and the first portion 110 supported on the first supporting component 210 and the second portion 120 supported on the second supporting component 220 are driven to move relatively, so that the electronic device disclosed in the embodiment of the present application also has a folding and unfolding capability, and good portability and a large display area are both considered.

The folding mechanism 300 includes a rotating shaft 310 and a first transmission component 320, the rotating shaft 310 can provide a rotating condition for the first supporting component 210 and the second supporting component 220, the first transmission component 320 is used for transmitting the force and changing the direction of the force, so as to generate a relative motion between different structures of the first supporting component 210 itself and generate a relative motion between different structures of the second supporting component 220 itself.

Specifically, the first support assembly 210 includes a first support portion 211 and a second support portion 212, and the first support portion 211 and the second support portion 212 are movably engaged along the axial direction of the rotation shaft 310 to change the maximum distance between the first support portion 211 and the second support portion 212 in the axial direction of the rotation shaft 310. Specifically, the first supporting portion 211 and the second supporting portion 212 may be rectangular plate-shaped structural members, or both may have other shapes, which is not limited herein. Alternatively, the first supporting portion 211 and the second supporting portion 212 may be movably engaged by a rail-type or shaft-hole-type sliding engagement structure, and the extending direction of the sliding engagement structure is parallel to the axial direction of the rotating shaft 310, so that the first supporting portion 211 and the second supporting portion 212 can be movably engaged in the axial direction of the rotating shaft 310. Of course, other structures such as the folding mechanism 300 can be used to form a movable fit relationship between the first supporting portion 211 and the second supporting portion 212 along the axial direction of the rotating shaft 310, and for the sake of brevity, the detailed description is omitted here.

Meanwhile, the second support assembly 220 includes a third support portion 221 and a fourth support portion 222, and the third support portion 221 and the fourth support portion 222 are movably matched along the axial direction of the rotating shaft 310, so as to change the maximum distance between the third support portion 221 and the fourth support portion 222 in the axial direction of the rotating shaft 310. The structural composition and assembly of the third support part 221 and the fourth support part 222 can be correspondingly arranged with reference to the first support assembly 210, and the description thereof is not repeated.

As described above, the display screen 100 is a flexible and retractable structure, that is, the display screen 100 can be deformed by using its own flexibility, and the display screen 100 also has a retractable capability, and this display screen 100 can be specifically formed by using a meta display technology, so that after being stretched within a preset range, the display screen 100 is ensured not to be distorted. Based on this, since the first support assembly 210 and the second support assembly 220 can be deformed in an axial direction of the rotating shaft 310, so as to change the maximum size of the first support assembly 210 and the second support assembly 220 in the axial direction of the rotating shaft 310, when one of two side edges of the display screen 100 with stretching capability is fixed on the first support portion 211 and the third support portion 221, and the other side edge of the display screen 100 is fixed on the second support portion 212 and the fourth support portion 222, so that the first support portion 211 and the second support portion 212 are away from each other (and the third support portion 221 and the fourth support portion 222 are away from each other), the display screen 100 can be stretched, so that the size of the display screen 100 in the axial direction of the rotating shaft 310 is increased, and the display area of the display screen 100 is further increased.

The above technical purpose is achieved by using the first transmission assembly 320 in the present application, and specifically, the first supporting portion 211 and the third supporting portion 221 are both fixed relative to the rotating shaft 310 in the axial direction, and the second supporting portion 212 and the fourth supporting portion 222 are both connected to the rotating shaft 310 through the first transmission assembly 320, so that under the condition that the first supporting portion 211 and the third supporting portion 221 are in foldable rotation fit through the rotating shaft 310, the second supporting portion 212 and the fourth supporting portion 222 can both move relative to the first supporting portion 211 along the axial direction of the rotating shaft 310, and the display screen 100 is driven to be deformed in an axial direction in a telescopic manner.

In the above technical solution, the first transmission assembly 320 can convert the rotation motion into the linear motion, so as to enable the relative motion between the first support portion 211 and the second support portion 212 along the axial direction of the rotating shaft 310 and enable the relative motion between the third support portion 221 and the fourth support portion 222 along the axial direction of the rotating shaft 310 without affecting the relative rotation of the first support assembly 210 and the second support assembly 220.

In the case that the number of the rotating shafts 310 is one, the rotating shafts 310 may be fixed on the first supporting portion 211, and the third supporting portion 221 is rotatably connected to the rotating shafts 310 to ensure that the third supporting portion 221 can rotate relative to the first supporting portion 211. In this case, the first transmission assembly 320 may include a screw rod and a nut, the screw rod is fixedly connected to the first supporting portion 211, the screw rod extends along the axial direction of the rotating shaft 310, the nut is fixed to the fourth supporting portion 222, and the nut is in transmission connection with the screw rod, so that in the process that the third supporting portion 221 drives the fourth supporting portion 222 to rotate relative to the first supporting assembly 210, the nut can move relative to the screw rod along the axial direction of the screw rod (i.e., the axial direction of the rotating shaft 310), and the fourth supporting portion 222 is driven to be away from the third supporting portion 221 along the axial direction of the rotating shaft 310. Meanwhile, the hinge such as a hinge can relatively fix the fourth supporting portion 222 and the second supporting portion 212 in the axial direction of the rotating shaft 310, and further in the process that the fourth supporting portion 222 moves relative to the third supporting portion 221 along the axial direction of the rotating shaft 310, the second supporting portion 212 can be driven to move relative to the first supporting portion 211 along the axial direction of the rotating shaft 310, so that the display screen 100 can be deformed in an extending and contracting manner in the axial direction of the rotating shaft 310.

Of course, other devices capable of relatively moving the second support portion 212 and the first support portion 211 along the axial direction of the rotating shaft 310 during the relative rotation of the first support portion 211 and the third support portion 221 may be used as the first transmission assembly 320. In brief, the first transmission assembly 320 may include a first bevel gear 350, a second bevel gear 350 and a cam, the first bevel gear 350 is fixedly connected to the rotating shaft 310, the second bevel gear 350 is engaged with the first bevel gear 350, the cam is mounted on a wheel axle of the second bevel gear 350, and makes both the second support portion 212 and the fourth support portion 222 be in transmission connection with the cam, and also converts the relative rotation between the first support portion 211 and the third support portion 221 into the linear reciprocating motion in the axial direction of the rotating shaft 310. In addition, the number of the rotating shafts 310 and the assembling relationship between the first supporting portion 211 and the third supporting portion 221 and the rotating shafts 310 are not unique, and the text is not described in detail herein in consideration of brevity.

The embodiment of the present application discloses an electronic device, wherein a display screen 100 is a flexible and retractable structure, a first portion 110 of the display screen 100 is supported on a first supporting component 210, a second portion 120 of the display screen 100 is supported on a second supporting component 220, and the first supporting component 210 and the second supporting component 220 are rotatably connected through a rotating shaft 310 of a folding mechanism 300. Moreover, the first support portion 211 and the second support portion 212 in the first support assembly 210 are movably matched in the axial direction of the rotating shaft 310, the third support portion 221 and the fourth support portion 222 in the second support assembly 220 are movably matched in the axial direction of the rotating shaft 310, and the second support portion 212 and the fourth support portion 222 are both connected with the rotating shaft 310 through the first transmission assembly 320, so that in the process that the first support portion 211 and the third support portion 221 relatively rotate, the second support portion 212 and the fourth support portion 222 can both move relative to the first support portion 211 along the axial direction of the rotating shaft 310, and further the display screens 100 supported on the first support assembly 210 and the second support assembly 220 can be telescopically deformed in the axial direction of the rotating shaft 310, so that the length-width ratio of the display screens 100 in the folded state and/or the unfolded state of the electronic device with folding capability is more consistent, and software adaptability and user experience are optimized.

In a specific embodiment of the present application, the first transmission assembly 320 includes a first guiding element 321 and a first sleeve 322, the first guiding element 321 is fixedly connected to the rotating shaft 310, the first sleeve 322 is sleeved outside the first guiding element 321, when the rotating shaft 310 and the first transmission assembly 320 are both one, the rotating shaft 310 is fixedly connected to the first supporting portion 211, and the first sleeve 322 is fixedly connected to the fourth supporting portion 222, so that the first sleeve 322 can rotate relative to the first guiding element 321 in a process that the third supporting portion 221 drives the fourth supporting portion 222 to rotate relative to the first supporting portion 211.

Meanwhile, one of the first guide member 321 and the first sleeve 322 is provided with a first guide groove 321a, the first guide groove 321a spirally extends around the axial direction of the rotating shaft 310, the other of the first guide member 321 and the first sleeve 322 is provided with a first connecting portion, and the first connecting portion extends into the first guide groove 321a, so that the first connecting portion is in transmission connection with the first guide groove 321a, and thus the first sleeve 322 and the first guide member 321 relatively move in the axial direction of the rotating shaft 310 during the relative rotation of the first sleeve 322 and the first guide member 321 by using the spirally extending first guide groove 321 a. Under the condition that the transmission assembly adopts the structure, parts in the transmission assembly are relatively few, the transmission relation among the parts is relatively simple, and the reliability of the transmission process can be improved.

Based on this, by having the second support portion 212 and the fourth support portion 222 be in transmission connection with the first guide 321 through the first sleeve 322, the second support portion 212 and the fourth support portion 222 can be moved relative to the first support portion 211 along the axial direction of the rotating shaft 310 under the condition that the first support portion 211 and the third support portion 221 are rotationally fitted. Of course, by setting the specific direction of the spiral extension of the first guide groove 321a, it can be ensured that the maximum distance between the first support portion 211 and the second support portion 212 gradually increases during the relative rotation and the mutual distance between the first support portion 211 and the third support portion 221 (i.e., the electronic apparatus is switched from the folded state to the unfolded state), and the maximum distance between the first support portion 211 and the second support portion 212 gradually decreases during the relative rotation and the mutual distance between the first support portion 211 and the third support portion 221 (i.e., the electronic apparatus is switched from the unfolded state to the folded state), so that the size of the display screen 100 in the axial direction of the rotating shaft 310 is adapted to the state of the electronic apparatus.

As described above, only one rotating shaft 310 may be disposed between the first supporting portion 211 and the third supporting portion 221, and the first transmission assembly 320 may be disposed to ensure that the first supporting portion 211 and the third supporting portion 221 have a relative rotation capability, and the second supporting portion 212 and the fourth supporting portion 222 can move relative to the first supporting portion 211 along the axial direction of the rotating shaft 310 by using the first transmission assembly 320, so that the display panel 100 can be deformed in an axial direction of the rotating shaft 310.

In another embodiment of the present application, the folding mechanism 300 includes two rotating shafts 310, and the two rotating shafts 310 are in transmission connection, so that the first supporting portion 211 and the third supporting portion 221 which are rotatably engaged by the two rotating shafts 310 can be switched between the unfolded state and the folded state. Specifically, the two shafts 310 may be respectively sleeved and fixed with a gear 350, and the two shafts 310 form a transmission fit relationship through the gears 350 engaged with each other. Meanwhile, one of the two rotating shafts 310 may be fixedly connected to the first supporting portion 211 through the first linkage rod 361, and the other may be fixedly connected to the third supporting portion 221 through the second linkage rod 362, so that the first supporting portion 211 and the third supporting portion 221 may be mutually switched between the unfolded state and the folded state in a rotation fit manner.

The first transmission assemblies 320 are disposed on both of the two rotation shafts 310, the first sleeve 322 and the second support portion 212 of one of the two first transmission assemblies 320 are relatively fixed in the axial direction of the rotation shaft 310, and the first sleeve 322 and the fourth support portion 222 of the other of the two first transmission assemblies 320 are relatively fixed in the axial direction of the rotation shaft 310. Specifically, the first guiding elements 321 of the two first transmission assemblies 320 are fixedly connected with the two rotating shafts 310 in a one-to-one correspondence manner, correspondingly, the two first sleeves 322 are sleeved outside the two first guiding elements 321 in a one-to-one correspondence manner, and the second supporting portion 212 and the fourth supporting portion 222 are respectively connected with the two first sleeves 322 through the rotating connecting element, so that the second supporting portion 212 and one first sleeve 322 are relatively fixed in the axial direction of the rotating shaft 310, and the fourth supporting portion 222 can also be relatively fixed with the other first sleeve 322 in the axial direction of the rotating shaft 310. Under the condition of adopting the technical scheme, the two rotating shafts 310 and the two first transmission assemblies 320 can respectively and independently drive the second supporting part 212 and the fourth supporting part 222, and the motion stability of the second supporting part 212 and the fourth supporting part 222 can be improved.

Of course, in the process that the second support portion 212 rotates with the first support portion 211 relative to the third support portion 221, in order to prevent the first sleeve 322 connected to the second support portion 212 from rotating with the second support portion 212 relative to the third support portion 221, and thus the first sleeve 322 cannot be displaced relative to the first guide 321 along the axial direction of the rotating shaft 310, in the above-mentioned technical solution, the two first sleeves 322 may be relatively fixed in the circumferential direction of the rotating shaft 310. Particularly, can set up the connecting rod and provide the axial positioning action along pivot 310 for two first sleeves 322, through making connecting rod fixed connection between two first sleeves 322, can make and respectively overlap and locate and can't produce relative rotation between two sleeves outside two first guide 321, thereby in two first guide 321 along two pivot 310 relative pivoted processes, guarantee two first sleeves 322 and respectively two relative first guide 321 along the axial displacement of pivot 310, and then drive the relative first supporting part 211 of second supporting part 212 and fourth supporting part 222 along the axial motion of pivot 310, and make display screen 100 produce flexible deformation in the axial of pivot 310.

In a case that the rotating shaft 310 and the first transmission assembly 320 between the first supporting portion 211 and the third supporting portion 221 are provided with two, the folding mechanism 300 further includes a limiting member 330, and the limiting member 330 is used for limiting the relative rotation between the two first sleeves 322, that is, the action of the limiting member 330 disclosed in this embodiment is similar to the action of the connecting rod fixedly connected between the two first sleeves 322 in the above embodiment.

In detail, the limiting member 330 includes a first limiting rod 331, a second limiting rod 332 and a cross beam 333, the first limiting rod 331 and the second limiting rod 332 both extend along the axial direction of the rotating shaft 310, that is, they are parallel to each other, and the first limiting rod 331 and the second limiting rod 332 are fixedly connected through the cross beam 333, so that the first limiting rod 331 and the second limiting rod 332 cannot rotate relatively.

Meanwhile, in the two first transmission assemblies 320 installed between the first supporting portion 211 and the third supporting portion 221, the first sleeve 322 of one is sleeved on the first limiting rod 331, and the first sleeve 322 and the first limiting rod 331 are relatively fixed in the circumferential direction of the rotating shaft 310. Correspondingly, the first sleeve 322 of the other of the two first transmission assemblies 320 is sleeved on the second limiting rod 332, and the first sleeve 322 and the second limiting rod 332 are relatively fixed in the circumferential direction of the rotating shaft 310, so that the two first sleeves 322 are limited to rotate relatively by the relatively fixed first limiting rod 331 and the second limiting rod 332.

Specifically, any one of the first sleeves 322 may be a cylindrical structural member, the first limiting rods 331 and the second limiting rods 332 may be correspondingly inserted into the two first sleeves 322 one by one, and the cross beam 333 may be connected to the end portions of the first limiting rods 331 and the second limiting rods 332 outside the first sleeves 322; meanwhile, by providing the first limiting rod 331 and the first sleeve 322 with the strip-shaped protrusion and the strip-shaped groove respectively extending along the rotating shaft 310, the first limiting rod 331 and the corresponding first sleeve 322 can be relatively fixed in the circumferential direction of the rotating shaft 310, and by adopting a similar scheme, the second limiting rod 332 and the corresponding other first sleeve 322 can be relatively fixed in the circumferential direction of the rotating shaft 310, so as to limit the first sleeve 322 to rotate along with the first guiding member 321.

In addition, the first limiting rod 331 and the second limiting rod 332 can be correspondingly inserted into the two rotating shafts 310 one by one, so that the installation stability of the limiting member 330 is relatively higher, and the structural stability of the electronic device is improved. Specifically, an avoiding hole may be formed in an end portion of the rotating shaft 310 facing the first limiting rod 331, and the first limiting rod 331 may be connected to the rotating shaft 310 in a plug-in fit manner, and the rotating shaft 310 may be ensured to rotate relative to the first limiting rod 331; in order to reduce the diameter of the rotating shaft 310 as much as possible and further reduce the overall size of the electronic device, a boss structure may be disposed at an end of the first limiting rod 331 close to the rotating shaft 310, and the diameter of the boss structure is smaller than that of the first limiting rod 331, so that the boss structure is inserted into and fitted with the avoiding hole in the rotating shaft 310. Accordingly, the second limiting rod 332 and the corresponding rotating shaft 310 may also form an inserting and rotating fit relationship, so as to ensure that the assembly relationship between the whole limiting member 330 and the rotating shaft 310 is more stable.

As described above, each of the first sleeves 322 is a cylindrical structure, and the cross member 333 is connected to the ends of the first and second position-limiting

rods

331 and 332.

When the above technical solution is adopted in the first support assembly 210 and the second support assembly 220, the fifth support portion 213 and the sixth support portion 223 can also be in transmission connection with the rotating shaft 310 through the above transmission assembly, so that when the first support portion 211 and the third support portion 221 are in rotation fit, on one hand, the fifth support portion 213 and the sixth support portion 223 can be ensured to rotate relatively therewith, and on the other hand, the fifth support portion 213 and the sixth support portion 223 can both move relative to the first support portion 211 along the axial direction of the rotating shaft 310, of course, the movement directions of the fifth support portion 213 and the second support portion 212 are opposite and move oppositely or away from each other, and similarly, the sixth support portion 223 and the fourth support portion 222 are also so that, during the unfolding process of the electronic device, the size of the display screen 100 in the axial direction of the rotating shaft 310 is increased, and during the folding process of the electronic device, the size of the display screen 100 in the axial direction of the rotating shaft 310 is decreased.

In order to further enlarge the display area of the electronic device, the housing 200 optionally further comprises a third supporting member 230, the second supporting member 220 is connected to one side of the first supporting member 210, and the third supporting member 230 is connected to the other side of the first supporting member 210. Of course, the second support assembly 220 is required to be located on the same side of the first support portion 211 and the second support portion 212, and similarly, the third support assembly 230 is required to be located on the same side of the first support portion 211 and the second support portion 212, so as to ensure that the relative movement between the first support portion 211 and the second support portion 212 along the axial direction of the rotating shaft 310 is not hindered. Correspondingly, the display screen 100 further includes a third portion 130, the third portion 130 is connected to a side of the first portion 110 facing away from the second portion 120, and the third portion 130 is supported on a third supporting component 230, that is, the first portion 110, the second portion 120 and the third portion 130 of the display screen 100 are respectively supported on the first supporting component 210, the second supporting component 220 and the third supporting component 230 of the casing 200.

Specifically, the size of the third supporting component 230 may be different from the size of the second supporting component 220, and may also be the same as the size of the second supporting component 220, which is not limited herein.

In addition, in the above embodiment, the first supporting assembly 210 may further include a fifth supporting portion 213, for this reason, the third supporting assembly 230 may also include a ninth supporting portion 233, the ninth supporting portion 233 is movably connected to a side of the seventh supporting portion 231, which is away from the eighth supporting portion 232, and two opposite end edges of the third portion 130 of the display screen 100 are respectively fixed to the eighth supporting portion 232 and the ninth supporting portion 233, so that under the condition that the first supporting portion 211 and the seventh supporting portion 231 are rotatably matched, the ninth supporting portion 233 can also move along the axial direction of the rotating shaft 310 relative to the first supporting portion 211 through the transmission assembly.

As described above, the electronic device has an unfolded state in which the display surface of the display screen 100 of the electronic device is a plane, that is, the display surfaces of the first portion 110, the second portion 120, and the third portion 130 are coplanar.

Alternatively, in the electronic device in the folded state, the third portion 130 may be located on a side of the second portion 120 facing away from the first portion 110, that is, the first portion 110, the second portion 120, and the third portion 130 are sequentially stacked.

In another embodiment of the present application, the second portion 120 and the third portion 130 may be both located on the back of the first portion 110, and the second portion 120 and the third portion 130 are disposed flush in the thickness direction of the first portion 110. That is, the second portion 120 and the third portion 130 are distributed along the axial direction perpendicular to the rotation axis 310 and the thickness direction of the first portion 110, which can reduce the thickness of the electronic device in the folded state and improve the convenience of the electronic device.

As described above, each of the first supporting portion 211 and the second supporting portion 212 may be a rectangular plate-shaped structure, and a movable fit relationship may be formed between the two through a sliding rail slider-like or shaft hole-like structure in the axial direction of the rotating shaft 310.

Accordingly, since the first portion 110 is supported by the first supporting portion 211 and the second supporting portion 212, and a rear cover and the like can be disposed on a side of the first supporting portion 211 and the second supporting portion 212 departing from the first portion 110, a limiting effect along the thickness direction of the first portion 110 can be provided for the guide supporting protrusion 214 and the guide avoiding opening 211a, and a stable guide action relationship can be formed between the guide supporting protrusion 214 and the guide avoiding opening 211a in the axial direction of the rotating shaft 310.

Similarly, a stable and reliable guiding fit relationship can be formed between the first supporting portion 211 and the fifth supporting portion 213, between the third supporting portion 221 and the fourth supporting portion 222, between the third supporting portion 221 and the sixth supporting portion 223, between the seventh supporting portion 231 and the eighth supporting portion 232, and between the seventh supporting portion 231 and the ninth supporting portion 233 in the axial direction of the rotating shaft 310 through a combination structure similar to the guiding and supporting projection 214 and the guiding and avoiding opening 211a, and a more comprehensive supporting effect can be provided for other positions on the display screen 100.

As described above, the electronic device disclosed in the embodiment of the present application belongs to a foldable electronic device, and during the unfolding and folding of the foldable electronic device, there are cases where the sizes of the inner side and the outer side are not equal, and further, there may be cases where the display screen 100 is stretched and damaged, or the display screen 100 is crushed and damaged. Therefore, in the present application, a water-drop-shaped avoiding space may be provided at a position where the first supporting component 210 and the second supporting component 220 are close to each other, so that the display screen 100 can be prevented from being squeezed in the process of being folded by being accommodated in the water-drop-shaped avoiding space under the condition of being folded. For the flip-out display screen 100, a retractable structure may be disposed at a position where the first supporting component 210 and the second supporting component 220 are close to each other, and in the process that the display screen 100 is folded, the first supporting component 210 and the second supporting component 220 both contract toward the position where the crease is far away from the display screen 100, so as to ensure that the flip-out display screen 100 is not stretched and damaged in the process of being folded. Of course, other structures of the housing 200 may be used to prevent the display screen 100 from being damaged during the folding process, which will not be described in detail herein.

In an embodiment of the present application, the folding mechanism 300 may further include a second transmission assembly 340, the third supporting portion 221 is in transmission connection with the rotating shaft 310 through the second transmission assembly 340, and under the condition that the first supporting portion 211 and the third supporting portion 221 are in rotation fit, the third supporting portion 221 is linearly reciprocated in a radial direction of the rotating shaft 310 relative to the rotating shaft 310, so as to prevent the display screen 100 from being stretched or squeezed during the folding process.

Specifically, the second driving assembly 340 may include a cam, and in the case that one rotating shaft 310 is disposed between the first supporting portion 211 and the second supporting portion 212, the cam may be sleeved and fixed on the rotating shaft 310, and the third supporting portion 221 may contact with a rim of the cam, so that the distance between the third supporting portion 221 and the rotating shaft 310 may be changed in the case that the third supporting portion 221 rotates relative to the first supporting portion 211. Accordingly, the installation form of the cam may be determined according to the folded state of the display screen 100, so that the display screen 100, whether in the fold-in structure or in the fold-out structure, may be prevented from being damaged during the folding process of the display screen 100.

As described above, two rotating shafts 310 may be disposed between the first supporting portion 211 and the third supporting portion 221, and the two rotating shafts 310 may be drivingly connected through the gear 350. In this case, both of the rotating shafts 310 may be provided with the second transmission assembly 340, and any one of the second transmission assemblies 340 may include the second guide member 341 and the second sleeve 342. Taking a second transmission assembly 340 and a rotating shaft 310 which are matched with each other as an example, the second guiding member 341 is fixedly connected with the rotating shaft 310, and the second sleeve 342 is sleeved outside the second guiding member 341, so that the second sleeve 342 and the second guiding member 341 can relatively rotate in the circumferential direction of the rotating shaft 310.

Meanwhile, one of the second guide member 341 and the second sleeve 342 is provided with a second guide groove, the other is provided with a second connecting portion, the second guide groove extends spirally around the axial direction of the rotating shaft 310, the second connecting portion extends into the second guide groove and is in transmission connection with the second guide groove, and then in the relative rotating process of the second sleeve 342 and the second guide member 341, the spirally extending second guide groove can be utilized, so that the second sleeve 342 and the second guide member 341 can generate linear motion along the axial direction of the rotating shaft 310.

In brief, the second transmission assembly 340 is similar or identical in structure and function to the first transmission assembly 320, both of which can convert rotational motion to linear motion.

However, the moving direction of the linear motion generated by the second transmission assembly 340 is the axial direction of the rotating shaft 310, and further, in order to ensure that the linear motion can act between the first supporting portion 211 and the corresponding rotating shaft 310 (and between the third supporting portion 221 and the corresponding rotating shaft 310), the electronic device disclosed in the embodiment of the present application further includes a reversing assembly 410, and the first supporting portion 211 and one rotating shaft 310, and the third supporting portion 221 and the other rotating shaft 310 are connected through the reversing assembly 410, so that the first supporting portion 211 and the third supporting portion 221 make linear reciprocating motion in the radial direction of the rotating shaft 310 relative to the rotating shaft 310 under the condition that the first supporting portion 211 and the third supporting portion 221 are rotatably matched.

Specifically, the reversing assembly 410 may include a first connecting rod 411 and a second connecting rod 412, for example, the reversing assembly 410 connected between the first supporting portion 211 and the corresponding rotating shaft 310, a first end of the first connecting rod 411 is rotatably engaged with the rotating shaft 310 in a radial direction around the rotating shaft 310, so that an included angle between the first connecting rod 411 and the rotating shaft 310 can be changed, and a first end of the second connecting rod 412 of the reversing assembly 410 is rotatably engaged with the second sleeve 342 in the radial direction around the rotating shaft 310, so that an included angle between the second connecting rod 412 and the second sleeve 342 can be changed. Meanwhile, the second end of the first link 411 and the second end of the second link 412 are hinged, and both the second end of the first link 411 and the second end of the second link 412 and the first support portion 211 are relatively fixed in the radial direction of the rotating shaft 310.

Moreover, by relatively fixing the second sleeves 342 of the two second transmission assemblies 340 in the circumferential direction of the rotating shaft 310, in the process that the first supporting portion 211 drives the rotating shaft 310 connected thereto to rotate relative to another rotating shaft 310, the second sleeves 342 are limited to rotate together with the second guiding element 341 (i.e., the rotating shaft 310), so that the second sleeves 342 can rotate relative to the second guiding element 341, and under the action of the spirally extending second guiding grooves, the second sleeves 342 can linearly move along the axial direction of the rotating shaft 310 relative to the second guiding element 341, and the included angle between the first connecting rod 411 and the second connecting rod 412 is changed, thereby changing the distance between the first supporting portion 211 connected through the reversing assembly 410 and the corresponding rotating shaft 310 in the radial direction of the rotating shaft 310. The limiting members 330 mentioned in the above embodiments may be adopted to provide fixing action for the two second sleeves 342 along the circumferential direction of the rotating shaft 310. Specifically, the limiting member 330 may be disposed on the second sleeve 342, and the first limiting rod 331 and the second limiting rod 332 of the limiting member 330 are respectively inserted into the two second sleeves 342, so that under the action of the first limiting rod 331 and the second limiting rod 332 which are fixedly connected, the two second sleeves 342 can be ensured to form a relatively fixed relationship in the axial direction of the rotating shaft 310.

Of course, since the second link 412 rotates with the first supporting portion 211 relative to the rotating shaft 310, in order to prevent the second link 412 connected to the second sleeve 342 from being restricted by the second sleeve 342 and being unable to rotate relative to the rotating shaft 310, an avoiding groove extending along the circumferential direction of the second sleeve 342 may be provided on the second sleeve 342, and the second link 412 is slidably mounted in the avoiding groove, so as to ensure that the first supporting portion 211 can normally drive the second link 412 to rotate relative to the second sleeve 342. In addition, in order to facilitate assembling the second connecting rod 412 and the second sleeve 342, the hinge seat 420 may be disposed, and the hinge seat 420 is slidably mounted in the avoiding groove, so that the second connecting rod 412 and the second sleeve 342 form a reliable connection relationship by matching the second connecting rod 412 with the hinge seat 420 in a hinge manner.

In addition, since the first link 411 and the second link 412 are both connected to the first support portion 211, and as the first support portion 211 rotates relative to the third support portion 221, the first link 411 and the third link rotate relative to each other, so that the position of the second end of each of the first link 411 and the second link 412 in the axial direction of the rotating shaft 310 changes, for this purpose, a sliding slot 211b extending in the axial direction of the rotating shaft 310 may be disposed on the first support portion 211, and the second end of each of the first link 411 and the second link 412 is connected to the first support portion 211 through a connecting rod 413.

Similarly, the assembly manner of the reversing element 410 disposed between the third supporting portion 221 and the rotating shaft 310 corresponding to the third supporting portion 221 can also refer to the above embodiment; in addition, in the case that the housing 200 includes the third supporting element 230, the reversing element 410 may be disposed between the seventh supporting portion 231 and the rotating shaft 310, and for the sake of brevity, the description thereof is omitted.

In addition, in the case of providing the second transmission assembly 340, in order to prevent the second supporting portion 212 and the fourth supporting portion 222 from interfering with the relative displacement between the first supporting portion 211 and the third supporting portion 221, one end of the first linkage rod 361 away from the first sleeve 322 may be in plug-in fit with the second supporting portion 212, and one end of the second linkage rod away from the first sleeve 322 may be in plug-in fit with the fourth supporting portion 222.
