All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, where appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described, and that the objects identified by "first," "second," etc. are generally of a type and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

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 support member 210 and a second support member 220, wherein the first support member 210 and the second support member 220 can be made of a hard material such as metal or plastic, so as to provide stable support for different portions of the display 100, and in detail, the display 100 includes a first portion 110 and a second portion 120, the first portion 110 is supported on the first support member 210, and the second portion 120 is supported on the second support member 220. Alternatively, the shapes and sizes of the first portion 110 and the second portion 120 may be correspondingly 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 embodiments of the present application is relatively wider.

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

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

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 coupled along an axial direction of the rotation shaft 310 to change a 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 structures, or may be structures with other shapes, which is not limited herein. Alternatively, the first supporting portion 211 and the second supporting portion 212 may form a loose-fitting relationship through a rail-type or shaft-hole sliding-fit structure, and the extending direction of the sliding-fit 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 may be ensured to be loose-fitted in the axial direction of the rotating shaft 310. Of course, other structures such as the folding mechanism 300 may be used to form the movable fit relationship between the first supporting portion 211 and the second supporting portion 212 along the axial direction of the rotating shaft 310, which is not described in detail here for brevity.

Meanwhile, the second supporting component 220 includes a third supporting portion 221 and a fourth supporting portion 222, and the third supporting portion 221 and the fourth supporting portion 222 are also movably matched along the axial direction of the rotating shaft 310, so as to change the maximum distance between the third supporting portion 221 and the fourth supporting portion 222 in the axial direction of the rotating shaft 310. The structural composition and assembly of the third supporting portion 221 and the fourth supporting portion 222 may be correspondingly set with reference to the first supporting component 210, and will not be repeated herein.

As described above, the display 100 is a flexible and stretchable structure, that is, the display 100 may not only deform by using its flexibility, but also stretch and contract, and the display 100 may be formed by using a meta display technology, so as to ensure that the display 100 will not be distorted after being stretched within a preset range. Because of this, since the first support member 210 and the second support member 220 can each be deformed to expand and contract in the axial direction of the rotation shaft 310, the maximum dimension of the first support member 210 and the second support member 220 in the axial direction of the rotation shaft 310 can be changed, and further, the display area of the display screen 100 can be further increased by fixing one of the both side edges of the display screen 100 having the stretching ability to the first support portion 211 and the third support portion 221 and fixing the other side edge of the display screen 100 to the second support portion 212 and the fourth support portion 222, such that the first support portion 211 and the second support portion 212 are separated from each other (and the third support portion 221 and the fourth support portion 222 are separated from each other), thereby increasing the dimension of the display screen 100 in the axial direction of the rotation shaft 310.

The first transmission assembly 320 is utilized to achieve the above technical objective in the present application, specifically, the first supporting portion 211 and the third supporting portion 221 are both fixed relatively 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 running fit with each other through the rotating shaft 310, the second supporting portion 212 and the fourth supporting portion 222 can both move relatively to the first supporting portion 211 along the axial direction of the rotating shaft 310, and drive the display screen 100 to stretch and deform in the axial direction.

In the above-mentioned technical solution, the first transmission assembly 320 can convert the rotational motion into the linear motion, so that the first supporting portion 211 and the second supporting portion 212 can move relatively along the axial direction of the rotating shaft 310, and the third supporting portion 221 and the fourth supporting portion 222 can move relatively along the axial direction of the rotating shaft 310 without affecting the relative rotation of the first supporting assembly 210 and the second supporting assembly 220.

In the case that the number of the rotation shafts 310 is one, the rotation shafts 310 may be fixed to the first support portion 211, and the third support portion 221 is rotatably connected to the rotation shafts 310, so as to ensure that the third support portion 221 can rotate relative to the first support portion 211. In this case, the first transmission assembly 320 may include a screw and a nut, the screw is fixedly connected with the first support portion 211, and the screw extends along the axial direction of the rotating shaft 310, the nut is fixed on the fourth support portion 222, and the nut is in transmission connection with the screw, so that in the process that the third support portion 221 drives the fourth support portion 222 to rotate relative to the first support assembly 210, the nut can move relative to the screw along the axial direction of the screw (i.e. the axial direction of the rotating shaft 310), so as to drive the fourth support portion 222 to be far away from the third support portion 221 along the axial direction of the rotating shaft 310. Meanwhile, the fourth supporting portion 222 and the second supporting portion 212 can be relatively fixed in the axial direction of the rotating shaft 310 by using a hinge or other hinge, and further, in the process that the fourth supporting portion 222 moves along the axial direction of the rotating shaft 310 relative to the third supporting portion 221, the second supporting portion 212 can be driven to move along the axial direction of the rotating shaft 310 relative to the first supporting portion 211, so that the display screen 100 can generate expansion deformation in the axial direction of the rotating shaft 310.

Of course, other devices can make the second support portion 212 and the first support portion 211 relatively move 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, and these devices can be used as the first transmission assembly 320. Briefly, the first transmission assembly 320 may include a first bevel gear 350, a second bevel gear 350, and a cam, wherein the first bevel gear 350 is fixedly connected with the rotating shaft 310, the second bevel gear 350 is engaged with the first bevel gear 350, the cam is mounted on a wheel shaft of the second bevel gear 350, and the second support portion 212 and the fourth support portion 222 are in driving connection with the cam, so that the relative rotation between the first support portion 211 and the third support portion 221 is converted into linear reciprocating motion in the axial direction of the rotating shaft 310. Moreover, the number of the rotating shafts 310 and the assembly relationship between the first supporting portion 211 and the third supporting portion 221 and the rotating shafts 310 are not unique, and the detailed description thereof is omitted here for brevity.

In the embodiment of the application, the display screen 100 is a flexible and retractable structure, the first portion 110 of the display screen 100 is supported on the first supporting component 210, the second portion 120 of the display screen 100 is supported on the second supporting component 220, and the first supporting component 210 and the second supporting component 220 are rotatably connected through the rotating shaft 310 of the folding mechanism 300. In addition, the first supporting portion 211 and the second supporting portion 212 in the first supporting assembly 210 are movably matched in the axial direction of the rotating shaft 310, the third supporting portion 221 and the fourth supporting portion 222 in the second supporting assembly 220 are movably matched in the axial direction of the rotating shaft 310, and the second supporting portion 212 and the fourth supporting portion 222 are connected with the rotating shaft 310 through the first transmission assembly 320, so that in the process of relatively rotating the first supporting portion 211 and the third supporting portion 221, 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, and further the display screen 100 supported on the first supporting assembly 210 and the second supporting assembly 220 can generate telescopic deformation in the axial direction of the rotating shaft 310, and accordingly the aspect ratio of the display screen 100 of the electronic device with folding capability in the folded state and/or the unfolded state is more coordinated, and software adaptability and user experience are optimized.

In a specific embodiment of the present application, the first transmission component 320 includes a first guiding element 321 and a first sleeve 322, where the first guiding element 321 is fixedly connected with the rotating shaft 310, the first sleeve 322 is sleeved outside the first guiding element 321, and under the condition that the number of the rotating shaft 310 and the first transmission component 320 is one, the rotating shaft 310 is fixedly connected with the first supporting portion 211, and the first sleeve 322 is fixedly connected with the fourth supporting portion 222, so that the first sleeve 322 can rotate relative to the first guiding element 321 in the 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 321 and the first sleeve 322 is provided with a first guide groove 321a, the first guide groove 321a is spirally extended around the axial direction of the rotation shaft 310, the other one of the first guide 321 and the first sleeve 322 is provided with a first connection part, and the first connection part is extended into the first guide groove 321a so that the first connection part is in driving connection with the first guide groove 321a, thereby relatively moving the first sleeve 322 and the first guide 321 in the axial direction of the rotation shaft 310 in the process of relatively rotating the first sleeve 322 and the first guide 321 by using the spirally extended first guide groove 321 a. Under the condition that the transmission assembly adopts the structure, parts in the transmission assembly are relatively fewer, and the transmission relation among the parts is simpler, so that the reliability of the transmission process can be improved.

Based on this, by making both the second support portion 212 and the fourth support portion 222 be in driving connection with the first guide 321 through the first sleeve 322, both the second support portion 212 and the fourth support portion 222 can be moved relative to the first support portion 211 in the axial direction of the rotation shaft 310 with the first support portion 211 and the third support portion 221 being in rotational engagement. Of course, by setting the specific direction of the spiral extension of the first guide groove 321a, it is ensured that the maximum distance between the first support portion 211 and the second support portion 212 gradually increases during the relative rotation of the first support portion 211 and the third support portion 221 and the distance from each other (i.e., the electronic device 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 of the first support portion 211 and the third support portion 221 and the distance from each other (i.e., the electronic device is switched from the unfolded state to the folded state), so that the dimension of the display screen 100 in the axial direction of the rotating shaft 310 is adapted to the state of the electronic device.

As described above, only one rotation shaft 310 may be disposed between the first supporting portion 211 and the third supporting portion 221, and by providing a set of first transmission assemblies 320, the first supporting portion 211 and the third supporting portion 221 may be guaranteed to have a capability of rotating relatively, and the second supporting portion 212 and the fourth supporting portion 222 may be guaranteed to move relatively to the first supporting portion 211 along the axial direction of the rotation shaft 310 by using the first transmission assemblies 320, so that the display screen 100 may be deformed in a telescopic manner in the axial direction of the rotation 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 with each other by using the two rotating shafts 310, can be switched between the unfolded state and the folded state. Specifically, the two rotating shafts 310 may be sleeved and fixed with gears 350, and the two rotating shafts 310 form a transmission fit relationship through the gears 350 meshed with each other. Meanwhile, one of the two rotating shafts 310 can be fixedly connected with the first supporting portion 211 through the first linkage rod 361, and the other one can be fixedly connected with the third supporting portion 221 through the second linkage rod 362, so that the first supporting portion 211 and the third supporting portion 221 can be mutually switched between an unfolded state and a folded state in a rotating fit mode.

The first transmission assemblies 320 are disposed on the two shafts 310, the first sleeve 322 and the second support portion 212 of one of the two first transmission assemblies 320 are fixed relative to each other in the axial direction of the shaft 310, and the first sleeve 322 and the fourth support portion 222 of the other of the two first transmission assemblies 320 are fixed relative to each other in the axial direction of the shaft 310. Specifically, the first guiding elements 321 of each of the two first transmission assemblies 320 are fixedly connected with the two rotating shafts 310 in a one-to-one correspondence manner, and 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 elements, so that the second supporting portion 212 and one first sleeve 322 can be relatively fixed in the axial direction of the rotating shaft 310, and the fourth supporting portion 222 and the other first sleeve 322 can be relatively fixed in the axial direction of the rotating shaft 310. In the case of adopting the above technical solution, the two rotating shafts 310 and the two first transmission assemblies 320 can respectively and individually drive the second support portion 212 and the fourth support portion 222, so that the movement stability of the second support portion 212 and the fourth support portion 222 can be improved.

Of course, in the process that the second support portion 212 rotates along 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 along with the second support portion 212 relative to the third support portion 221, the first sleeve 322 cannot be displaced relative to the first guide 321 along the axial direction of the rotating shaft 310, and in the above technical scheme, two first sleeves 322 may be relatively fixed in the circumferential direction of the rotating shaft 310. Specifically, the connecting rod may be configured to provide the positioning function along the axial direction of the rotating shaft 310 for the two first sleeves 322, and the connecting rod is fixedly connected between the two first sleeves 322, so that the two sleeves respectively sleeved outside the two first guiding elements 321 cannot rotate relatively, and therefore, in the process that the two first guiding elements 321 rotate relatively along with the two rotating shafts 310, the two first sleeves 322 can move along the axial direction of the rotating shafts 310 relatively to the two first guiding elements 321, and further, the second supporting portion 212 and the fourth supporting portion 222 are respectively driven to move along the axial direction of the rotating shafts 310 relatively to the first supporting portion 211, and the display screen 100 is enabled to generate expansion deformation in the axial direction of the rotating shafts 310.

In the case that the rotation shaft 310 and the first transmission assembly 320 between the first supporting portion 211 and the third supporting portion 221 are both provided with two, the folding mechanism 300 further includes a limiting member 330, where the limiting member 330 is used to limit the relative rotation between the two first sleeves 322, that is, the effect of the limiting member 330 disclosed in the present embodiment is similar to the effect 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 extend along the axial direction of the rotating shaft 310, that is, the first limiting rod 331 and the second limiting rod 332 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 of the first transmission assemblies 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 one 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 relative rotation between the two first sleeves 322 is limited by the relatively fixed first limiting rod 331 and the relatively fixed second limiting rod 332.

Specifically, any 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 threaded through the two first sleeves 322, 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 arranging the strip-shaped protrusions and the strip-shaped grooves extending along the rotating shaft 310 on the first limiting rod 331 and the first sleeve 322 respectively, 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 that the first sleeve 322 is limited to rotate along with the first guide 321.

In addition, the first stop lever 331 and the second stop lever 332 can be correspondingly inserted and matched with the two rotating shafts 310, so that the mounting stability of the stop member 330 is relatively higher, and the structural stability of the electronic device is improved. Specifically, an avoidance hole may be provided at an end of the rotating shaft 310 facing the first limiting rod 331, so that the first limiting rod 331 can be connected with the rotating shaft 310 in a plug-in matching manner, and the rotating shaft 310 can 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, the end of the first limiting rod 331, which is close to the rotating shaft 310, can be provided with a boss structure, and the diameter of the boss structure is smaller than that of the first limiting rod 331, so that the boss structure is in plug-in fit with the avoidance hole on the rotating shaft 310. Accordingly, the second stop lever 332 and the corresponding rotating shaft 310 can also form a plug-in and rotation fit relationship, so as to ensure that the assembly relationship between the whole stop member 330 and the rotating shaft 310 is more stable.

As described above, any of the first sleeves 322 is a cylindrical structural member, and the cross beam 333 is connected to the ends of the first and second stopper rods 331 and 332. In another embodiment of the present application, any first sleeve 322 is provided with a avoiding opening 322a penetrating through the first sleeve 322 along the axial direction of the rotating shaft 310, that is, the first sleeve 322 has an open structure. On this basis, the beam 333 may be located at the middle part of the first limiting rod 331 along the axial direction of the rotating shaft 310, and correspondingly, the middle part of the second limiting rod 332 along the axial direction of the rotating shaft 310 is connected with the other end of the beam 333, so that the fixed connection effect provided by the beam 333 for the first limiting rod 331 and the second limiting rod 332 is more reliable, and the overall structural stability of the limiting member 330 is further improved.

Meanwhile, since the avoidance openings 322a are formed in each first sleeve 322, after the first sleeves 322 are sleeved outside the first guide 321, the whole limiting piece 330 can be matched with the first sleeves 322 from one ends of the two first sleeves 322, the first limiting rod 331 (and the second limiting rod 332) is retracted to extend into the first sleeves 322 continuously, the cross beam 333 can be movably matched with the avoidance openings 322a of the two first sleeves 322, the cross beam 333 is positioned between the two first sleeves 322, and any one of the first sleeves 322 is in limiting fit with the cross beam 333 along the circumferential direction of the rotating shaft 310, so that relative rotation between the two first sleeves 322 is prevented.

Under the above technical scheme, the assembly difficulty between the limiting member 330 and the first transmission assembly 320 is relatively small, and other structures are not required to be arranged on the first limiting member 330, the second limiting member 330 and the two first sleeves 322, and the relative rotation between the two first sleeves 322 can be limited by using the beam 333 of the limiting member 330; meanwhile, by utilizing the avoidance gap 322a formed in the first sleeve 322, the first sleeve 322 can move in the axial direction of the rotating shaft 310 beyond the cross beam 333 and relative to the limiting part 330, so that the size of the whole limiting part 330 in the axial direction of the rotating shaft 310 can be reduced, the structure of the electronic equipment is more compact, the avoidance gap 322a can enable the weight of the two first sleeves 322 to be relatively smaller, the electronic equipment is further light, and the user experience is improved.

Specifically, the rotating member may include a second linkage rod 362, any first sleeve 322 may be sleeved with the second linkage rod 362, and the second linkage rod 362 and the first sleeve 322 that correspond to each other are in running fit, and the second support portion 212 and the fourth support portion 222 are respectively fixedly connected with the corresponding second linkage rod 362, that is, in the process of the relative movement of the first sleeve 322 and the first guide 321 along the axial direction of the rotating shaft 310, the second support portion 212 and the fourth support portion 222 are driven to move along the axial direction of the rotating shaft 310 relative to the first support portion 211.

In another embodiment of the present application, the first supporting component 210 further includes a fifth supporting portion 213, the fifth supporting portion 213 is movably connected to a side of the first supporting portion 211 facing away from the second supporting portion 212 along the axial direction of the rotating shaft 310, that is, in the first supporting component 210, the second supporting portion 212, the first supporting portion 211 and the fifth supporting portion 213 are sequentially distributed along the axial direction of the rotating shaft 310, and in this case, the second supporting portion 212, the first supporting portion 211 and the fifth supporting portion 213 may be utilized to provide a supporting function for the first portion 110 of the display screen 100. Specifically, the edges of the two opposite ends of the first portion 110 of the display screen 100 along the axial direction of the rotating shaft 310 are respectively fixed to the second supporting portion 212 and the fifth supporting portion 213, so that the first supporting component 210 can extend toward the opposite sides along the axial direction of the rotating shaft 310, and further the display screen 100 can also stretch and expand toward the opposite sides of the display screen 100, so that on one hand, the deformation amplitude of the display screen 100 can be enlarged, and on the other hand, the expansion degree of the first portion 110 of the display screen 100 is basically similar, the display effect of any position on the first portion 110 of the display screen 100 is equivalent, and the display effect of the first portion 110 of the display screen 100 is improved.

Similarly, the second supporting component 220 may further include a sixth supporting portion 223, where the sixth supporting portion 223 is movably connected to a side of the third supporting portion 221, which is away from the fourth supporting portion 222, along the axial direction of the rotating shaft 310, so that the second portion 120 of the display screen 100 is supported by the fourth supporting portion 222, the third supporting portion 221 and the sixth supporting portion 223, which are sequentially distributed along the axial direction of the rotating shaft 310, so as to expand the deformation range of the second portion 120, and make the display effect at any position on the second portion 120 equivalent, thereby further improving the display effect of the second portion 120 of the display screen 100.

In the case that 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 may also be in transmission connection with the rotating shaft 310 through the above transmission assembly, so that, in the case that the first support portion 211 and the third support portion 221 are in running fit, on one hand, the fifth support portion 213 and the sixth support portion 223 may be guaranteed to be capable of relatively rotating with each other, and on the other hand, the fifth support portion 213 and the sixth support portion 223 may also be capable of relatively moving with respect to the first support portion 211 along the axial direction of the rotating shaft 310, and, of course, the movement directions of the fifth support portion 213 and the second support portion 212 are opposite, and the sixth support portion 223 and the fourth support portion 222 may also be capable of relatively moving with each other or moving with respect to each other, 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 expand the display area of the electronic device, the housing 200 may further include a third support member 230, the second support member 220 is connected to one side of the first support member 210, and the third support member 230 is connected to the other side of the first support member 210. Of course, the second supporting component 220 needs to be located on the same side of the first supporting portion 211 and the second supporting portion 212, and similarly, the third supporting component 230 needs to be located on the other same side of the first supporting portion 211 and the second supporting portion 212, so as to ensure that the relative movement between the first supporting portion 211 and the second supporting portion 212 along the axial direction of the rotating shaft 310 is not hindered. Accordingly, the display 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 the third supporting component 230, that is, the first portion 110, the second portion 120, and the third portion 130 of the display 100 are respectively supported on the first supporting component 210, the second supporting component 220, and the third supporting component 230 of the housing 200. Under the condition of adopting the technical scheme, the display area of the display screen 100 can be further enlarged, the expansibility of the electronic equipment is improved, and further the user experience is improved.

Meanwhile, the third supporting component 230 includes a seventh supporting portion 231 and an eighth supporting portion 232 movably matched along the axial direction of the rotating shaft 310, the seventh supporting portion 231 and the first supporting portion 211 are relatively fixed with the rotating shaft 310 in the axial direction, and the eighth supporting portion 232 and the second supporting portion 212 are connected with the rotating shaft 310 through transmission components, so that the seventh supporting portion 231 and the first supporting portion 211 can rotate relatively, and under the condition that the seventh supporting portion 231 is rotatably matched with the first supporting portion 211, the eighth supporting portion 232 and the second supporting portion 212 can rotate relatively, on the one hand, and on the other hand, the eighth supporting portion 232 can move along the axial direction of the rotating shaft 310 relative to the first supporting portion 211, so that the eighth supporting portion 232 and the seventh supporting portion 231 can drive the third portion 130 of the display screen 100 to generate telescopic deformation in the axial direction of the rotating shaft 310. Specifically, the size of the third supporting component 230 may be different from the size of the second supporting component 220, or may 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 component 210 may further include a fifth supporting portion 213, and therefore, the third supporting component 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 facing 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 on the eighth supporting portion 232 and the ninth supporting portion 233, so that 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 component under the condition that the first supporting portion 211 and the seventh supporting portion 231 are rotationally matched.

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. In the folded state, the second portion 120 and the third portion 130 of the display screen 100 may be folded to the same side of the first portion 110, and the display screen 100 of the first portion 110 may be exposed, so that the electronic device in the folded state may also be used by a user, which is convenient for the user to use in the scenes of viewing information, making a phone call, and the like. 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 stacked in order.

In another embodiment of the present application, the second portion 120 and the third portion 130 may be located at 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 in the axial direction perpendicular to the rotation shaft 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 use of the electronic device.

As described above, the first supporting portion 211 and the second supporting portion 212 may each have a rectangular plate-like structure, and may form a movable fit relationship therebetween in the axial direction of the rotating shaft 310 through a slide rail slider-like or shaft hole-like structure. In another embodiment of the present application, one of the first support portion 211 and the second support portion 212 may be provided with a guide support protrusion 214, the other one is provided with a guide avoidance opening 211a, the guide support protrusion 214 is movably matched with the guide avoidance opening 211a in the axial direction of the rotating shaft 310 and is in limit fit in the direction perpendicular to the axial direction of the rotating shaft 310, so that the guide and limit effects are provided for the movable matching relationship of the first support portion 211 and the second support portion 212 in the axial direction of the rotating shaft 310 by using the movably matched guide support protrusion 214 and the guide support opening; in addition, in the process of separating the first supporting portion 211 and the second supporting portion 212 from each other, the guide supporting protrusion 214 protruding from the first supporting portion 211 (or the second supporting portion 212) may also be used to provide a supporting effect for the middle portion of the first portion 110, so that the first supporting portion 211 and the second supporting portion 212 are prevented from being separated from each other, and a gap is prevented from being generated, so that a supporting effect cannot be provided for a corresponding portion on the first portion 110 of the display screen 100.

Accordingly, since the first portion 110 is supported on the first supporting portion 211 and the second supporting portion 212, and the side of the first supporting portion 211 and the second supporting portion 212 facing away from the first portion 110 may be provided with a rear cover or the like, a limit function along the thickness direction of the first portion 110 may be provided for the guide supporting protrusion 214 and the guide avoiding opening 211a, so that the guide supporting protrusion 214 and the guide avoiding opening 211a may form a stable guide function relationship in the axial direction of the rotating shaft 310.

Similarly, 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, a stable and reliable guiding fit relationship can be formed in the axial direction of the rotating shaft 310 by a combined structure similar to the guiding supporting protrusion 214 and the guiding 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 embodiments of the present application belongs to a foldable electronic device, and in the process of unfolding and folding the foldable electronic device, there are cases where the sizes of the inner side and the outer side are not equal, and thus the display screen 100 may be damaged by stretching, or the display screen 100 may be damaged by extrusion. Therefore, in the present application, the drop-shaped avoidance space may be provided at the position where the first support assembly 210 and the second support assembly 220 are close to each other, so that the display screen 100 can be prevented from being extruded in the folded process by accommodating the drop-shaped avoidance space in the folded state of the display screen 100. For the eversion display screen 100, a telescopic structure may be disposed at the position where the first support component 210 and the second support component 220 are close to each other, and in the process of folding the display screen 100, the first support component 210 and the second support component 220 are both retracted toward the inside of the display screen 100 at the position where the folds far away from the display screen 100 are located, so as to ensure that the eversion display screen 100 is not damaged due to stretching in the folding process. Of course, other configurations of the housing 200 may be used to prevent the display 100 from being damaged during folding, which will not be described in detail herein.

In a specific embodiment of the present application, the folding mechanism 300 may further include a second transmission assembly 340, where the third supporting portion 221 is in transmission connection with the rotating shaft 310 through the second transmission assembly 340, and in a case where the first supporting portion 211 and the third supporting portion 221 are in rotation fit, the third supporting portion 221 makes a linear reciprocating motion relative to the rotating shaft 310 in a radial direction of the rotating shaft 310, so as to prevent the display screen 100 from being stretched or extruded in a folding process.

Specifically, the second transmission assembly 340 may include a cam, and in case that one rotation shaft 310 is provided between the first support portion 211 and the second support portion 212, the cam may be fixed to the rotation shaft 310 in a sleeved manner, and by contacting the third support portion 221 with the rim of the cam, the interval between the third support portion 221 and the rotation shaft 310 may be changed in case that the third support portion 221 rotates relative to the first support portion 211. Accordingly, the installation form of the cam can be determined according to the folded condition of the display screen 100, so that the display screen 100 can be prevented from being damaged in the process of being folded, whether the display screen 100 is in an inward folded structure or an outward folded structure.

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

Meanwhile, one of the second guiding element 341 and the second guiding sleeve 342 is provided with a second guiding groove, the other one is provided with a second connecting part, the second guiding groove extends spirally around the axial direction of the rotating shaft 310, the second connecting part stretches into the second guiding groove and is in transmission connection with the second guiding groove, and further in the process of relative rotation of the second guiding sleeve 342 and the second guiding element 341, the second guiding groove which extends spirally can be utilized, so that linear motion along the axial direction of the rotating shaft 310 can be generated between the second guiding element 341 and the second guiding sleeve 342.

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

However, the direction of movement of the linear movement converted by the second transmission assembly 340 is the axial direction of the rotating shaft 310, and further, in order to ensure that the aforementioned linear movement 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 application further includes a reversing assembly 410, where the first supporting portion 211 and one rotating shaft 310, and the third supporting portion 221 and the other rotating shaft 310 are all connected by the reversing assembly 410, so that the first supporting portion 211 and the third supporting portion 221 perform linear reciprocating movement 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 rotationally matched.

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

Moreover, by fixing the second sleeves 342 of the two second transmission assemblies 340 relatively in the circumferential direction of the rotating shaft 310, the second sleeves 342 are limited to rotate together with the second guide 341 (i.e. the rotating shaft 310) in the process that the first supporting portion 211 drives the rotating shaft 310 connected with the second transmission assemblies to rotate relatively to the other rotating shaft 310, so that the second sleeves 342 can rotate relatively to the second guide 341, under the action of the second guide grooves extending in a spiral manner, the second sleeves 342 can move linearly along the axial direction of the rotating shaft 310 relatively to the second guide 341, and the included angle between the first connecting rod 411 and the second connecting rod 412 is changed, so that the distance between the first supporting portion 211 connected by the reversing assembly 410 and the corresponding rotating shaft 310 in the radial direction of the rotating shaft 310 is changed. Wherein, the limiting member 330 mentioned in the above embodiment may be used to provide the fixing effect for the two second sleeves 342 in the direction along the circumferential direction of the rotating shaft 310. Specifically, the second sleeve 342 may be provided with a limiting member 330, 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 the two second sleeves 342 can form a relatively fixed relationship in the axial direction of the rotating shaft 310 under the action of the fixedly connected first limiting rod 331 and second limiting rod 332.

Of course, since the second link 412 rotates along 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 limited by the second sleeve 342 and not being able to rotate relative to the rotating shaft 310, an avoidance 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 avoidance groove, so that the first supporting portion 211 can normally drive the second link 412 to rotate relative to the second sleeve 342. In order to facilitate assembly of the second link 412 and the second sleeve 342, a hinge seat 420 may be provided, and the hinge seat 420 may be slidably mounted in the avoidance groove, and further, the second link 412 and the second sleeve 342 may be reliably connected by hinge-coupling the second link 412 and the hinge seat 420.

In addition, since the first link 411 and the second link 412 are 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 positions of the second ends of the first link 411 and the second link 412 in the axial direction of the rotation shaft 310 are changed, a sliding groove 211b extending in the axial direction of the rotation shaft 310 may be provided in the first support portion 211, and the second ends of the first link 411 and the second link 412 may be connected to the first support portion 211 through the 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 component 230, the reversing component 410 may also be disposed between the seventh supporting portion 231 and the rotating shaft 310, which is not described in detail herein for brevity.

In addition, when the second transmission assembly 340 is provided, in order to prevent the second support portion 212 and the fourth support portion 222 from interfering with the relative displacement between the first support portion 211 and the third support portion 221, the end of the first link 361 away from the first sleeve 322 may be engaged with the second support portion 212 in a plug-in manner, and the end of the second link away from the first sleeve 322 may be engaged with the fourth support portion 222 in a plug-in manner.
