It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 14, an electronic device is disclosed in an embodiment of the present application, and the disclosed electronic device includes a flexible screen 200, a frame assembly 100, and a driving assembly 300.

The flexible screen 200 is a display component of the electronic device, and the user can browse information and operate the electronic device through the flexible screen 200. Optionally, the flexible screen 200 may be deployed or collapsed. When the electronic device is not used by the user, the flexible screen 200 is folded in a normal condition in consideration of carrying convenience, and at this time, the size of the electronic device can be reduced, so that the electronic device is convenient for the user to carry. When a user needs to use the electronic device and has a large screen demand, the flexible screen 200 can be unfolded, the area of the flexible screen 200 is increased, a larger display area 210 is provided for the user, and the user can browse information or operate conveniently, for example, when the user has the display demand of a full screen such as game playing, the flexible screen 200 can be unfolded, so that the operation experience of the user is improved.

The frame assembly 100 is a base member of the electronic device, and surrounds the flexible screen 200, so as to protect the flexible screen 200 to a certain extent, and meanwhile, the frame assembly 100 can also be used as a mounting base of the flexible screen 200, and the flexible screen 200 can be mounted through the frame assembly 100. The frame assembly 100 includes a first frame 110 and a second frame 120 that are relatively movable. Alternatively, both the first frame 110 and the second frame 120 may be concave structures. When the first frame 110 is fastened to the second frame 120, an accommodating space is defined therebetween, and the flexible screen 200 is at least partially disposed in the accommodating space. In consideration of the fact that the flexible screen 200 can be unfolded or folded, one end of the flexible screen 200 is connected to the second frame 120, and the other end of the flexible screen 200 is movable relative to the first frame 110. Of course, the other end of the flexible screen 200 may also be rolled up by the rolling device, and at this time, the other end of the flexible screen 200 may also move relative to the first frame 110. In this way, when the second frame 120 is relatively far away from the first frame 110, the second frame 120 may drive one end of the flexible screen 200 to move synchronously, and accordingly, the other end of the flexible screen 200 may move relative to the first frame 110, or the flexible screen 200 is released from the rolling device, so that a larger area of the display area 210 may be provided for a user, so as to enhance user experience. When the second frame 120 and the first frame 110 are relatively close to each other, the flexible screen 200 can be folded to reduce the area, so that the user can conveniently carry the screen.

It should be noted that, during the folding process of the flexible screen 200, the other end of the flexible screen 200 may be pulled by the driving member to hide a portion of the flexible screen 200 inside the frame assembly 100, so as to reduce the size of the display area 210 of the flexible screen 200 and the entire electronic device. Of course, the other end of the flexible screen 200 may also be rolled by a rolling device, which may also reduce the size of the display area 210 of the flexible screen 200 and the whole electronic device. The present application does not limit the driving manner of the flexible screen 200 during the folding process, as long as the flexible screen 200 can be driven to fold when the second frame 120 and the first frame 110 are relatively close to each other.

In order to make the first frame 110 and the second frame 120 relatively far away or relatively close to each other, a driving assembly 300 is added in the embodiment of the present application. Specifically, a first cavity 1111 is disposed on the first frame 110, a second cavity 1211 is disposed on the second frame 120, and the driving assembly 300 is disposed in the first cavity 1111 and the second cavity 1211. Optionally, a first cavity 1111 is formed on an end surface of the first frame 110 facing the second frame 120, a second cavity 1211 is formed on an end surface of the second frame 120 facing the first frame 110, the first cavity 1111 and the second cavity 1211 are disposed opposite to each other, so as to form a whole cavity, and the driving assembly 300 may be disposed in the whole cavity, thereby implementing the installation of the driving assembly 300.

The actuating assembly 300 includes an electro-deformable member 310. the electro-deformable member 310 is a structural member that deforms when energized, and the manner in which the electro-deformable member 310 deforms can be controlled by varying the energization. For example, a positive voltage may deform the electro-deformable member 310 towards one side, such as bending, and the like, and a negative voltage may deform the electro-deformable member 310 towards the other side, such as bending, and the like, and in the event of a power failure, the electro-deformable member 310 may return to the original state. It should be noted that specific principles related to the electro-deformable member 310 can be found in the related art, and will not be described in detail here.

In the embodiment of the present invention, when the electro-deformable element 310 is energized, it deforms, so as to generate a driving action on at least one of the first cavity 1111 and the second cavity 1211, and the direction of the driving action is parallel to the direction of the relative movement of the first frame 110 and the second frame 120. For example, the electro-deformable element 310 deforms when being powered on, and the electro-deformable element 310 drives at least one of the first cavity 1111 and the second cavity 1211, and under the driving action, the first frame 110 and the second frame 120 may relatively move away from or close to each other, and meanwhile, the second frame 120 synchronously drives one end of the flexible screen 200 to move, so as to realize the expansion or the folding of the flexible screen 200. It should be noted that the driving assembly 300 may be fixed to the first frame 110, and at this time, the driving assembly 300 may drive the second frame 120 to move away from or close to the first frame 110, or the driving assembly 300 may be fixed to the second frame 120, and at this time, the driving assembly 300 may drive the first frame 110 to move away from or close to the second frame 120, or the driving assembly 300 may be unfixed to both the first frame 110 and the second frame 120, and at this time, the driving assembly 300 may be divided into two parts, one part is engaged with the first cavity 1111 of the first frame 110, and the other part is engaged with the second cavity 1211 of the second frame 120, so that the first frame 110 and the second frame 120 may be simultaneously driven to move away from or close to each other.

Based on the above arrangement, when a user needs a larger display screen, a first form of voltage may be applied to deform the electro-deformable member 310 toward the first direction, so that the first frame 110 and the second frame 120 are away from each other, so as to unfold the flexible screen 200, thereby enlarging the display area of the flexible screen 200; when the user needs a smaller display screen or carries the display screen, the second type of voltage may be applied to deform the electro-deformable member 310 toward a second direction opposite to the first direction, so as to approach the first frame 110 and the second frame 120 to fold the flexible screen 200, thereby reducing the display area of the flexible screen 200. Based on above-mentioned setting, compare in conventional motor drive mode, drive assembly 300 in this application is succinct more, small and exquisite, has reduced the shared space of drive assembly 300, has alleviated the influence to the overall arrangement of other electronic components in electronic equipment.

In some embodiments, the first frame 110 may be a concave frame structure including two first bracket parts 111 disposed opposite to each other and a housing part 112 connecting the two first bracket parts 111, as shown in fig. 1 and 2. The two first frame parts 111 are respectively disposed at both sides of the flexible panel 200, and the housing part 112 is disposed at an end of the flexible panel 200. In this way, a part of the flexible panel 200 can be enclosed by the two first frame parts 111 and the housing part 112, and the flexible panel 200 can be restricted. Optionally, the first bracket portion 111 is provided with at least one first cavity 1111, for example, one, two, three, five, etc., and the number of the first cavities 1111 provided in the first bracket portion 111 is not limited in the embodiment of the present invention. Each of the first cavities 1111 may receive a portion of the driving assembly 300 therein, so that a space for disposing the driving assembly 300 may be provided.

Likewise, the second frame 120 may be a concave frame structure including two second bracket parts 121 disposed opposite to each other and a fixing part 122 connecting the two second bracket parts 121, as shown in fig. 1 and 2. The two second support portions 121 are respectively disposed at two sides of the flexible screen 200, the fixing portion 122 is disposed at an end of the flexible screen 200, the second support portions 121 correspond to the first support portions 111, and the fixing portion 122 and the housing portion 112 are respectively disposed at two ends of the flexible screen 200 and are disposed oppositely. Thus, another part of the flexible screen 200 can be enclosed by the two second bracket parts 121 and the fixing part 122, so that the flexible screen 200 can be limited. Optionally, the second bracket portion 121 is provided with at least one second cavity 1211, such as one, two, three, five, and so on, and in the embodiment of the present application, the number of the second cavities 1211 provided on the second bracket portion 121 is not limited. Each of the second cavities 1211 may receive another portion of the driving assembly 300 therein, so that a space for the driving assembly 300 may be provided.

Based on the above arrangement, when the first frame 110 and the second frame 120 are in the relatively retracted state, a portion of the flexible screen 200 is received inside the frame assembly 100, and another portion of the flexible screen 200 is displayed outside for the user to browse or operate. Alternatively, one end of the flexible screen 200 is fixedly connected to the fixing portion 122, and the other end of the flexible screen 200 is slidably connected to the first frame 110.

In some embodiments, the flexible screen 200 may include a display area 210 and a hidden area 220, wherein the display area 210 is a portion exposed outside the frame assembly 100 for a user to view or manipulate; the hidden area 220 is a portion located inside the frame assembly 100. When the flexible screen 200 is unfolded, the partially hidden area 220 moves out of the frame assembly 100 to become the display area 210, so that the area of the display area 210 can be increased; when the flexible screen 200 is folded, a portion of the display area 210 moves from outside the frame assembly 100 into the frame assembly 100 to become the hidden area 220, so that the area of the display area 210 can be reduced. Typically, the display area 210 is located at an upper layer of the frame assembly 100, and the hidden area 220 is located at a lower or middle layer of the frame assembly 100. The flexible screen 200 may be provided at a central portion thereof with a support structure, such as a shaft member, around which the flexible screen 200 is wound, and the flexible screen 200 may be bent, curled, and the like by the support structure, so that the flexible screen 200 appears as a display area 210 at an upper layer of the frame assembly 100 and a hidden area 220 at a lower layer or a middle layer of the frame.

In some embodiments, the first bracket portion 111 defines a first cavity 1111, and the second bracket portion 121 defines a second cavity 1211, such that the first cavity 1111 is opposite to the second cavity 1211. The driving assembly 300 includes a first mounting member 320, and a portion of the first mounting member 320 may be disposed within the first cavity 1111 and another portion may be disposed within the second cavity 1211. Alternatively, the first mounting member 320 may be a cylindrical structure, such as a cylinder, a polygonal prism, or the like. To accommodate the drive assembly 300, the cross-sectional area of the first cavity 1111 is not less than the cross-sectional area of the first mounting member 320 and the cross-sectional area of the second cavity 1211 is not less than the cross-sectional area of the first mounting member 320 in the embodiments of the present application. The first mounting member 320 is provided with an electro-deformable member 310, and an end of the electro-deformable member 310 protrudes out of a side of the first mounting member 320. One end of the first mounting member 320 is disposed in the second cavity 1211 and is fixedly connected to the second bracket portion 121, and the other end of the first mounting member 320 is movably disposed in the first cavity 1111. Alternatively, a plurality of mounting structures, such as mounting grooves, may be provided at intervals on the first mounting member 320 along the length direction thereof, and the electro-deformable member 310 is mounted to the first mounting member 320 by the mounting structures such that the end of the electro-deformable member 310 protrudes out of the side of the first mounting member 320.

Under the condition of power supply, the electro-deformable element 310 deforms, so that the end part of the electro-deformable element abuts against the side wall of the first cavity 1111 or the second cavity 1211, and a friction force is generated between the end part of the electro-deformable element and the inner side wall of the first cavity 1111 or the second cavity 1211, and under the action of the friction force, the first frame 110 and the second frame 120 can be relatively far away or relatively close to each other. In case of power failure, the end of the electro-deformable member 310 is detached from the sidewall of the first cavity 1111 or the second cavity 1211, thereby stopping the driving action on the first frame 110 or the second frame 120.

In other alternative embodiments, two first cavities 1111 may be disposed on the first frame portion 111 side by side along the thickness direction of the electronic device, correspondingly, two second cavities 1211 may be disposed on the second frame portion 121 side by side along the thickness direction of the electronic device, and the two first cavities 1111 and the two second cavities 1211 are disposed opposite to each other, respectively. The drive assembly 300 comprises a first mounting member 320 and a second mounting member 330, wherein the first mounting member 320 is disposed within one set of oppositely disposed first 1111 and second 1211 cavities and the second mounting member 330 is disposed within the other set of oppositely disposed first 1111 and second 1211 cavities. Alternatively, the first and second mounting

members

320 and 330 may each be a cylindrical structure, such as a cylinder, a polygonal prism, or the like. To accommodate the drive assembly 300, in the embodiment of the present application, the cross-sectional area of the first cavity 1111 is not less than the cross-sectional area of the first and second mounting

elements

320, 330 and the cross-sectional area of the second cavity 1211 is not less than the cross-sectional area of the first and second mounting

elements

320, 330.

The first mounting element 320 and the second mounting element 330 are respectively provided with an electro-deformable member 310, and ends of the electro-deformable member 310 protrude out of sides of the first mounting element 320 and sides of the second mounting element 330. Alternatively, a plurality of mounting structures, such as mounting grooves, may be provided at intervals along the respective length directions of the first mounting element 320 and the second mounting element 330, respectively, and the electro-deformable element 310 is mounted to the first mounting element 320 and the second mounting element 330 through the mounting structures, such that the end portions of the electro-deformable element 310 protrude out of the side surfaces of the first mounting element 320 and the second mounting element 330.

Further, one end of the first mounting member 320 is disposed in one of the second cavities 1211 and is fixedly connected to the second bracket portion 121, and the other end of the first mounting member 320 is movably disposed in the corresponding first cavity 1111; meanwhile, one end of the second mounting member 330 is movably disposed in the other second cavity 1211, and the other end of the second mounting member 330 is disposed in the corresponding first cavity 1111 and fixedly connected to the first bracket 111.

Based on the above arrangement, the first mounting member 320 and the electro-deformable member 310 thereon, and the second mounting member 330 and the electro-deformable member 310 thereon are mutually matched, so that the first frame 110 and the second frame 120 can be driven to move relatively, the stability and smoothness of the relative movement are improved, and the problems of jamming, vibration and the like in the relative movement process can be relieved.

Optionally, a plurality of the electro-deformable members 310 are respectively disposed on the first mounting member 320 and the second mounting member 330, the plurality of electro-deformable members 310 are disposed at intervals, and the plurality of electro-deformable members 310 may cooperate to realize the relative movement of the first frame 110 and the second frame 120.

In some embodiments, the driving assembly 300 may drive the first and

second stand portions

111 and 121 relatively away from each other under the condition that the electro-deformable member 310 is periodically negatively charged. As shown in fig. 13, when the electro-deformable member 310 is deformed negatively, it bends to the right, and the end of the electro-deformable member 310 presses against the side wall of the chamber and generates a friction force to the right, thereby driving the frame to move to the right at a time. When the electro-deformable member 310 is periodically negatively charged, the electro-deformable member 310 deforms in the following manner: negative electrical deformation-power-off reset-negative electrical deformation-power-off reset, etc., so that the frame can be moved gradually toward the right side by acting on the frame multiple times.

Conversely, the driving assembly 300 may drive the first and

second frame portions

111 and 121 relatively close to each other in the case where the electro-deformable member 310 is periodically positively charged. As shown in fig. 14 in particular, when the electro-deformable member 310 is deformed positively, it bends towards the left, at which point the end of the electro-deformable member 310 presses against the side wall of the cavity and creates a friction force towards the left, thereby driving the frame to move towards the left at a time. When the electro-deformable member 310 is periodically positively charged, the electro-deformable member 310 deforms in the following manner: positive electrical deformation-power-off reset-positive electrical deformation-power-off reset, etc., so that the frame can be moved gradually toward the left side by acting on the frame multiple times.

When the electro-deformable member 310 is de-energized, it is in an initial state, as shown in fig. 12.

Referring to fig. 11, in some embodiments, the electro-deformable member 310 includes a deformable block 311, a first plate 312, and a second plate 314. Alternatively, the deformation block 311 may be a long strip structure, a sheet structure, etc., and the specific shape thereof is not limited. The first plate 312 and the second plate 314 are both disposed at an area of the deformation block 311 near the edge, and the first plate 312 and the second plate 314 are symmetrically disposed with respect to the axis of the deformation block 311. Therefore, the two symmetrical sides of the deformation block 311 can be electrified through the first pole plate 312 and the second pole plate 314, so that the deformation block 311 deforms more symmetrically, and the interaction force between the electro-deformation member 310 and the side walls of the cavities is more uniform. For example, when the deformation block 311 is a long strip structure, the first pole plate 312 and the second pole plate 314 are symmetrically disposed at two end regions close to the length direction of the deformation block 311; when the deformation block 311 has a sheet structure, such as a disc structure, the connection line between the first plate 312 and the second plate 314 passes through the center of the disc structure.

In order to supply power to the electro-deformable member 310, in the embodiment of the present invention, the first plate 312 is connected to the first wire 314, the second plate 314 is connected to the second wire 315, and both the first wire 314 and the second wire 315 are connected to the flexible cable 600. Alternatively, the first electrode plate 312 may be a positive electrode plate, the second electrode plate 314 may be a negative electrode plate, and accordingly, the first wire 314 is a positive electrode wire, and the second wire 315 is a negative electrode wire; of course, the first electrode plate 312 may be a negative electrode plate, the second electrode plate 314 may be a positive electrode plate, the first lead 314 may be a negative lead, and the second lead 315 may be a positive lead. In this way, the flexible cable 600 may transmit an electrical signal to the first plate 312 through the first conducting wire 314 and transmit the electrical signal to the second plate 314 through the second conducting wire 315 to supply power to the first plate 312 and the second plate 314, respectively, so that the deformation block 311 may be deformed.

It should be noted here that, because the electro-deformable element 310 is disposed in the first cavity 1111 and the second cavity 1211, and the flexible cable 600 supplies power to the electro-deformable element 310, in order to communicate the flexible cable 600 with the outside, in the embodiment of the present disclosure, the wire hole 1112 is disposed on the side wall of the first cavity 1111 or the second cavity 1211, and the flexible cable 600 may penetrate through the wire hole 1112 and be connected to a wire network of the electronic device, so that the electro-deformable element 310 may be connected to the wire network of the electronic device, so as to control the deformation of the electro-deformable element 310.

Considering that the driving assembly 300 is movable relative to at least one of the first cavity 1111 and the second cavity 1211 when the driving assembly 300 drives the first frame 110 and the second frame 120 to move away from each other, in order to prevent the driving assembly 300 from being separated from at least one of the first cavity 1111 and the second cavity 1211, in the embodiment of the present application, the driving assembly 300 includes a plurality of sets of the electrostrictive members 310 arranged at intervals. Alternatively, multiple sets of electro-deformable members 310 may be disposed on the first or second mounting

elements

elements

320, 330. Thus, when the electro-deformable member 310 is energized, the electro-deformable member 310 within the first cavity 1111 or the second cavity 1211 deforms in the same manner. For example, when the driving assembly 300 is fixed in the second cavity 1211, in an initial condition of no power supply, none of the electro-deformable members 310 located in the first cavity 1111 is deformed, and at this time, the first frame 110 is not separated from the second frame 120; when the power is turned on, the edges of the multiple groups of electro-deformable members 310 in the first cavity 1111 are bent and deformed in the direction away from the second frame 120 and press the inner wall of the first cavity 1111, so as to drive the first frame 110 for the first time; then, the power is cut off, and the electro-deformable member 310 is separated from the inner wall of the first cavity 1111 and returns to the initial state; then, the same voltage as that in the first time is applied again, edges of the multiple groups of electro-deformable members 310 in the first cavity 1111 are bent and deformed again in a direction away from the second frame 120, and press the inner wall of the first cavity 1111, so that the first frame 110 is driven for the second time; and so on, finally, after a plurality of times of driving, the distance between the first frame 110 and the second frame 120 reaches a preset value, and the electrification is stopped. If the first frame 110 and the second frame 120 need to be relatively close to each other, the direction of the applied voltage can be changed, and after multiple driving, the first frame 110 and the second frame 120 can be folded. In addition, the specific process and principle for fixing the driving assembly 300 to the first frame 110 are similar to the above-mentioned specific process and principle for fixing the driving assembly 300 to the second frame 120, and are not repeated herein.

It should be noted that as the driving assembly 300 moves relative to the first frame 110 or the second frame 120, less and less of the electro-deformable members 310 are located in the first cavity 1111 or the second cavity 1211. In the embodiment of the present invention, in order to prevent the driving assembly 300 from completely separating from the first cavity 1111 or the second cavity 1211, when the flexible screen 200 is completely unfolded, the electro-deformable element 310 still exists in the first cavity 1111 or the second cavity 1211, so as to ensure that the first frame 110 and the second frame 120 can be folded.

In addition, the driving assembly 300 may be movably disposed in the first cavity 1111 and the second cavity 1211 respectively, that is, the driving assembly 300 may move in both the first cavity 1111 and the second cavity 1211. At this time, the driving assembly 300 may be divided into two parts, wherein the electro-deformable element 310 in one part is disposed in the first cavity 1111, and the electro-deformable element 310 in the other part is disposed in the second cavity 1211. When energized, the voltages applied to the two portions of the electro-deformable member 310 are opposite, thereby causing the deformation of the two portions of the electro-deformable member 310 in opposite directions. For example, when the first frame 110 and the second frame 120 are relatively far away from each other, the electro-deformable members 310 in the first cavity 1111 are all bent and deformed in a direction away from the second frame 120, and the electro-deformable members 310 in the second cavity 1211 are all bent and deformed in a direction away from the first frame 110; when the first frame 110 and the second frame 120 are relatively close to each other, the electro-deformable members 310 in the first cavity 1111 are bent and deformed toward the second frame 120, and the electro-deformable members 310 in the second cavity 1211 are bent and deformed toward the first frame 110. Of course, in this embodiment, in order to prevent the driving assembly 300 from moving freely in the first cavity 1111 and the second cavity 1211, a limiting structure (not shown) may be further added. For example, when the driving assembly 300 moves a certain distance in the first cavity 1111, the driving assembly 300 is limited by the limiting structure to keep moving in the first cavity 1111, so as to ensure that the driving assembly 300 moves in the second cavity 1211.

In some embodiments, the electronic device has first and second sides that are oppositely disposed. Optionally, the first side and the second side are spaced apart along a thickness direction of the electronic device. The flexible screen 200 includes first and second ends that are oppositely disposed. It is understood that the first and second ends are disposed along the expanding or collapsing direction of the flexible screen 200. The first end of the flexible screen 200 is fixedly connected to the region of the fixing portion 122 located on the first side, and the second end of the flexible screen 200 is wound from the first side to the second side and extends toward the second housing 120. It is understood that the first side is an upper side in a thickness direction of the electronic device, and the second side is a lower side in the thickness direction of the electronic device, whereby the flexible screen 200 is folded back from the upper side of the electronic device to the lower side of the electronic device after passing through the first frame 110.

Based on the above arrangement, when the first frame 110 and the second frame 120 are relatively folded, the second end of the flexible screen 200 is located at an end of the first frame 110 adjacent to the second frame 120, and when the first frame 110 and the second frame 120 are relatively unfolded, the second end of the flexible screen 200 is located at an end of the first frame 110 far from the second frame 120. It can be understood that, during the relative folding process of the first frame 110 and the second frame 120, as the flexible screen 200 moves, the portion of the flexible screen 200 located on the upper side of the electronic device moves into the frame assembly 100, so as to reduce the display area of the flexible screen 200. During the relative expansion of the first frame 110 and the second frame 120, as the flexible screen 200 moves, the flexible screen 200 on the lower side of the electronic device partially moves out of the frame assembly 100, thereby increasing the display area of the flexible screen 200. In addition, the second end is located at one end of the first frame 110 adjacent to the second frame 120, and is not limited to the end of the first frame 110, and may include an area near the end; similarly, the second end is located at an end of the first frame 110 far from the second frame 120, and is not limited to the end of the first frame 110, and may include a region near the end.

In some embodiments, the electronic device further includes a roller 400 and a support member 500, the roller 400 is rotatably disposed in the housing portion 112, and the support member 500 is movably disposed on the first frame portion 111. The middle portion (the portion between the two ends) of the flexible screen 200 is wound around the roller 400, and the roller 400 can support the flexible screen 200 during the unfolding or folding process of the flexible screen 200 and facilitate the movement of the flexible screen 200. The other end of the flexible screen 200 facing away from the fixing portion 122 is connected to a support member 500, as shown in fig. 4 and 6. The flexible screen 200 includes a display area 210 at an upper layer and a hidden area 220 at a lower or middle layer, and the roller 400 is positioned between the two layers of the flexible screen 200. Thus, when the first frame 110 and the second frame 120 are relatively far away from each other, one end of the flexible screen 200, which is connected to the fixing portion 122, gradually gets away from the first frame 110, the roller 400 rotates clockwise, the flexible screen 200 moves forward on the roller 400, the hidden area 220 inside the frame assembly 100 gradually moves out of the frame assembly 100 and changes into the display area 210, and thus the area of the display area 210 is increased. When the first frame 110 and the second frame 120 are relatively close to each other, one end of the flexible screen 200 connected to the support member 500 moves relative to the first frame 110 in a direction away from the roller 400, the roller 400 rotates counterclockwise, the flexible screen 200 moves on the roller 400 in a reverse direction, the display region 210 located outside the frame assembly 100 gradually moves into the frame assembly 100 and is changed into the hidden region 220, and thus the area of the display region 210 is reduced.

It should be noted here that, in order to fold the flexible screen 200, a pulling mechanism may be connected to the supporting member 500, and the pulling mechanism may be the driving assembly 300, or may be in other forms, such as a motor lead screw nut assembly, a motor rack and pinion assembly, an electromagnetic assembly, and the like.

Further, the first frame part 111 defines a sliding part 1113, the supporter 500 is movably disposed on the sliding part 1113, and the sliding part 1113 extends in a first direction parallel to a direction in which the first frame 110 and the second frame 120 relatively move. Optionally, the sliding portion 1113 may be a sliding slot, a sliding rail, or other structures, and two ends of the supporting member 500 are slidably connected to the sliding portions 1113 on the two first frame portions 111, respectively, so as to ensure that the unfolding or folding process of the flexible screen 200 is more stable and smooth.

Of course, in other embodiments, the electronic device may further include a reel (not shown), the reel may be rotatably disposed in the housing portion 112, and the other end of the flexible screen 200 facing away from the fixing portion 122 is wound on the reel. Alternatively, the reel may be connected to a driving motor, the driving motor serves as a power source for rotating the reel, the reel is driven to rotate by the driving motor, and the other end of the flexible screen 200 is pulled by the reel, so that the flexible screen 200 can be folded. It should be noted that the driving motor and the driving assembly 300 are cooperatively controlled to prevent the driving action of the flexible screen 200 from interfering and affecting the unfolding or folding process of the flexible screen 200.

The electronic equipment in the embodiment of the application can be a mobile phone, a tablet computer, an electronic book reader, wearable equipment, vehicle-mounted equipment, unmanned aerial vehicle equipment and the like, and the embodiment of the application does not limit the specific type of the electronic equipment.

In summary, the electronic device disclosed in the embodiment of the present application does not adopt a motor for driving, so that the whole electronic device has a simple structure and a reduced volume, and when there is a display requirement for a full-screen such as playing games and watching videos, the flexible screen 200 can be unfolded to realize a large-area screen display, thereby improving the user experience of extreme games, audio and video; when the size of the electronic device is reduced due to carrying, the flexible screen 200 can be folded, so that the purposes of reducing the size and facilitating carrying are achieved.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
