Further, referring to fig. 6, the fixing bracket 112 is formed with a mounting cavity 1122, and the mounting cavity 1122 can be used to partially receive the second case 12 and the rolling device 40 for placing the electronic device 100 and other electronic components of the electronic device 100, such as a motherboard, a battery, and the like.

Specifically, referring to fig. 5 and 6, in the present embodiment, the fixing bracket 112 includes a main body 1121 and a top plate 1123, the main body 1121 forms the mounting cavity 1122, the top plate 1123 is disposed on the main body 1121, and an upper surface of the top plate 1123 is fixedly connected to the flat portion 211 of the flexible display panel assembly 20 to support the flat portion 211 of the flexible display panel assembly 20. A slide groove 1124 is formed between the main body 1121 and the top plate 1123. Specifically, in the embodiment shown in fig. 6, a sliding slot 1124 is formed on the main body 1121, the top plate 1123 is located above the sliding slot 1124 and covers the sliding slot 1124, and the first housing 11 can be slidably connected to the second housing 12 through the sliding slot 1124.

It is understood that in other embodiments, the slide groove 1124 may be formed at the bottom of the top plate 1123, without limitation. The top plate 1123 and the main body 1121 may be integrally formed or may be separately formed.

Referring to fig. 1 to 6, the second housing 12 is located at one side of the first housing 11, and the second housing 12 can slide relative to the first housing 11 to be at least partially received in the mounting cavity 1122. The second housing 12 includes a sliding end cap 121 and a sliding bracket 122, and the sliding bracket 122 is disposed in the sliding end cap 121 and is fixedly connected to the sliding end cap 121.

Referring to fig. 7, the sliding end cap 121 is slidably connected to the fixing bracket 112 of the first housing 11. The sliding end cap 121 includes a first side plate 1211 and two second side plates 1212 connected to two ends of the first side plate 1211, the first side plate 1211 and the two second side plates 1212 define a receiving space 1213, and the sliding bracket 122 is received in the receiving space 1213.

It is noted that in the description of the present application, such as the "first case" and the "second case" described above, the terms "first" and "second" are used for descriptive purposes only and do not indicate that the housing assembly has only two cases, nor does it imply that the first case is more important than the second case, or that the terms "first" and "second" are not to be interpreted as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

It should be noted that, in the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 4 to 7, the flexible display panel assembly 20 includes a flexible display panel 21 and a supporting member 22, and the supporting member 22 and the flexible display panel 21 are stacked and fixedly connected along a thickness direction of the flexible display panel assembly 20.

It should be noted that in the description of the present application, it is to be understood that the terms "thickness", "upper", "lower", "inner" and "outer" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present application.

In this embodiment, the flexible display 21 includes a flat portion 211 and an expanded portion 212. The flat portion 211 is exposed outside the housing assembly 10. Specifically, the flat portion 211 is disposed above the fixed bracket 112 and is at least partially fixedly connected to the top plate 1123 of the fixed bracket 112. The expansion portion 212 can be hidden in the housing assembly 10, one end of the expansion portion 212 is connected to the flat portion 211, the other end is connected to the winding device 40, the middle portion of the expansion portion 212 is wound around the sliding bracket 122, and the expansion portion 212 is at least partially received in the receiving space 1213 of the second case 12.

When the second housing 12 slides relative to the first housing 11 away from the first housing 11, the rolling device 40 can gradually release the expansion portion 212, and the second housing 12 brings the expansion portion 212 to be exposed from the housing assembly 10, so as to form a display portion of the electronic device 100 together with the expansion portion 211.

In this embodiment, the flat portion 211 and the top plate 1123 may be fixed by a double-sided tape or an optical tape. It is understood that in other embodiments, other fixing means may be used, for example, magnetic attraction may be used for fixing, and in such embodiments, a magnetic element may be attached to the back of the flat portion 211, and the top plate 1123 may be made of a magnetic material, and the two are magnetically attracted together, and the specific arrangement is not limited herein.

It can be understood that, referring to fig. 1, fig. 2 and fig. 6, when only the flat portion 211 of the flexible display screen 21 is exposed from the housing assembly 10, the display area of the display portion of the electronic device 100 is small, and at this time, the first shell 11 and the second shell 12 are fitted together to form a smaller-sized housing assembly 10, and the electronic device 100 is in the narrow screen mode. In this case, second housing 12 may be partially housed in mounting cavity 1122 of first housing 11, or may be entirely housed in mounting cavity 1122.

Referring to fig. 3, 4 and 7, when the second shell 12 slides relative to the first shell 11 to a side away from the first shell 11, the second shell 12 drives the expansion portion 212 to gradually expose at least a portion of the expansion portion from the inside of the housing assembly 10, so that the exposed expansion portion 212 and the exposed expansion portion 211 jointly form a display portion of the electronic device 100, and at this time, the area of the display portion of the electronic device 100 is larger. When the second housing 12 is slid to the limit position in the direction away from the first housing 11, the exposed area of the expanded portion 212 is maximized and the display portion area is also maximized (see fig. 4), and at this time, the electronic apparatus 100 is in the wide screen mode. In the embodiment of the present application, the electronic apparatus 100 is capable of switching between the narrow screen mode and the wide screen mode.

In addition, in the illustrated embodiment, the second shell 12 carries the extension portion 212 to be partially exposed from the housing assembly 10, that is, when the electronic device 100 is in the wide screen mode, the extension portion 212 is only partially exposed from the housing assembly 10. It is understood that in some embodiments, the extension portion 212 may also be entirely exposed from the housing assembly 10 when the electronic device 100 is in the wide screen mode, and is not limited herein.

Referring to fig. 5 to 8, in the present embodiment, the supporting member 22 is stacked below the expanding portion 212, and the supporting member 22 at least partially covers the expanding portion 212. The support 22 serves to support the extension portion 212, and the support 22 moves following the extension portion 212 to support the extension portion 212 when the extension portion 212 moves.

The support 22 includes a plurality of support pieces 221 arranged at intervals, and the support pieces 221 can be bent in the sliding direction of the second housing 12 such that the middle portion of the expanded portion 212 is wound around the sliding bracket 122.

As such, the support piece 221 may be provided to support the expansion portion 212 without preventing the expansion portion 212 from being bent and curled. Moreover, the supporting piece 221 enables the force-bearing body 1121 of the expansion portion 212 to be the supporting piece 221 when the expansion portion is bent or curled, so as to improve the service life of the flexible display 21.

In the embodiment of the present application, the supporting piece 221 has a bending characteristic in the sliding direction of the second housing 12 (i.e., the transverse direction of the electronic device 100), and has a rigid characteristic in the longitudinal direction of the electronic device 100. That is, in the embodiment of the present application, the supporting piece 221 may be bent in a lateral direction of the electronic device 100 but may not be bent in a longitudinal direction. Specifically, the support piece 221 may be a steel sheet.

It should be noted that in the description of the present application, it is to be understood that the terms "transverse" and "longitudinal" refer to orientations and positional relationships based on the orientations and positional relationships shown in the drawings, and are used for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present application.

In addition, referring to fig. 6 and 7, in the present embodiment, the surface of the top plate 1123 of the fixing bracket 112 connected to the flat portion 211 is flush with the surface of the supporting member 22 connected to the expanded portion 212, that is, the upper surface of the supporting member 22 is flush with the upper surface of the top plate 1123.

Thus, when the extension portion 212 is driven by the second shell 12 to be at least partially exposed from the housing assembly 10, the upper surface of the supporting member 22 is flush with the upper surface of the top plate 1123, so that there is no significant height difference between the flat portion 211 and the exposed extension portion 212, and the flexible display screen assembly 20 is relatively flat, and the flatness of the flexible display screen assembly 20 is ensured, which not only improves the operation experience of the user, but also improves the aesthetic appearance of the electronic device 100.

It should be noted that "flush" herein may be understood as the height of both surfaces being the same, there being no height difference between the two surfaces, or the height difference between the two surfaces being within the manufacturing error and the assembling error.

Referring to fig. 5 to 7, in the present embodiment, the guide shaft 30 is disposed in the mounting portion 1223 of the second housing 12 and is rotatably connected to the second housing 12, that is, the guide shaft 30 can rotate in the mounting portion 1223. The intermediate portion of the expanded portion 212 is wound around the guide shaft 30.

In this manner, the guide shaft 30 may guide when the expansion portion 212 moves, so that the expansion portion 212 can be smoothly unfolded to be exposed from the housing assembly 10.

In addition, the presence of the guide shaft 30 may maintain the form of the extension portion 212, thereby preventing the extension portion 212 from being largely deformed during movement to reduce the life of the flexible display 21.

Specifically, in the present embodiment, the guide shaft 30 may make the extension portion 212 substantially U-shaped, so that the extension portions 212 on both sides of the guide shaft 30 can be kept flat to improve the life of the flexible display 21. It is understood that in some embodiments, the electronic device 100 may not include the guide shaft 30, as long as the second shell 12 can move the extension portion 212 to expose the housing assembly 10.

Referring to fig. 3, 5, 8 and 9, in the present embodiment, the housing assembly 10 further includes a pressing member 13, and the pressing member 13 is fixedly connected to the second shell 12. When the extension portion 212 is at least partially exposed from the housing assembly 10, the pressing member 13 presses the edge of the extension portion 212 exposed from the housing assembly 10.

In this manner, when the flexible display panel assembly 20 is expanded, the presence of the pressing member 13 can prevent the expanded portion 212 from being bent and wrinkled in the thickness direction of the flexible display panel assembly 20 (i.e., the direction perpendicular to the sliding direction and the direction perpendicular to the flat portion 211), so that the expanded portion 212 can be kept unfolded flat.

Specifically, referring to fig. 1, fig. 2 and fig. 6, in the present embodiment, when the expansion portion 212 is completely hidden in the housing assembly 10, the pressing member 13 presses against an edge of at least a part of the flat portion 211. Referring to fig. 3 and 4 and fig. 7, when the extension portion 212 is at least partially exposed from the housing assembly 10, the pressing member 13 presses the edge of the extension portion 212 exposed from the housing assembly 10. That is, in the embodiment of the present application, when the electronic device 100 is in the narrow-screen mode, the pressing member 13 presses the edge of the at least partially flat portion 211. When the electronic device 100 is in the wide screen mode, the pressing member 13 presses the edge of the expanded portion 212 exposed from the inside of the housing assembly 10.

Of course, it is understood that in the illustrated embodiment, in a certain state of the movement process of the second housing 12, the pressing member 13 presses against the partially flattened portion 211 in addition to the exposed expanded portion 212.

Furthermore, it will be appreciated that, since the flat portion 211 is fixedly connected to the top plate 1123 of the fixing bracket 112, no bending or wrinkling occurs during the movement, and therefore, in other embodiments, the pressing member 13 may not press against the edge of the flat portion 211 when the extension portion 212 is completely hidden in the housing assembly 10.

It should be noted that, in the embodiment of the present application, the pressing member 13 presses the flat portion 211 or the expanded portion 212 of the flexible display panel assembly 20, which is directly contacted to press against the flat portion 211 or the expanded portion 212 of the flexible display panel assembly 20, but does not affect the sliding of the flexible display panel assembly 20, that is, the pressing member 13 only limits the movement of the expanded portion 212 along the thickness direction of the flexible display panel assembly 20 to prevent the occurrence of the rotation, and does not affect the movement of the expanded portion 212 along the sliding direction of the second shell 12, that is, does not affect the expansion of the expanded portion 212. In addition, since the support sheet 221 of the support member of the flexible display panel assembly 20 has rigidity, the support sheet 221 may also limit the movement of the extension portion 212 of the flexible display panel assembly 20 in the thickness direction to a certain extent to prevent the extension portion 212 from wrinkling or arching during the movement. In this way, the support piece 221 and the pressing piece 13 cooperate with each other to more effectively restrict the movement of the expansion portion 212.

Referring to fig. 5, 8 and 9, in the embodiment of the present application, the pressing element 13 is disposed on the sliding end cap 121 of the second shell 12 and is fixedly connected to the sliding end cap 121. In particular, the pressing element 13 may be integrally formed with the sliding end cap 121, and the pressing element 13 may be a part of the sliding end cap 121, that is, in one possible embodiment, the sliding end cap 121 may form the pressing element 13. Specifically, the pressing member 13 may be connected to an edge of the second side plate, and is formed to extend from the second side plate 1212 of the sliding end cap 121 to the inside of the sliding end cap 121.

Referring to fig. 9, in the embodiment shown in fig. 9, the pressing member 13 directly presses the flexible display panel assembly 20, and the pressing member 13 may be made of a flexible material. Thus, the flexible display panel assembly 20 can be prevented from being damaged due to the large friction between the pressing member 13 and the flexible display panel assembly 20.

Referring to fig. 10, in some embodiments, the pressing member 13 may include a body 131 and a filling layer 132, the body 131 is fixedly connected to the second shell 12, the filling layer 132 is disposed on the body 131, the body 131 and the flexible display panel assembly 20 are disposed at a distance from each other, the filling layer 132 fills a gap between the flexible display panel assembly 20 and the body 131, and the body 131 presses an edge of the expansion portion through the filling layer 132.

In such embodiments, the filler layer 132 may be made of a flexible material or have some flexibility without scratching the flexible display assembly 20 by causing a large friction with the flexible display assembly 20. For example, the filling layer 132 may be a silicone gel layer, a foam layer, or an element having a flexible property.

Furthermore, it is understood that in other embodiments, the pressing element 13 may be another part or structure connected to the second shell 12, for example, the pressing element 13 may be disposed in the second shell 12 and can extend out of the second shell 12 to press against the flat portion 211 or the expanded portion 212, when the expanded portion 212 is completely hidden in the housing assembly 10, the pressing element 13 may extend into the second shell 12 to press against an edge of at least a part of the flat portion 211, and when the expanded portion 212 is at least partially exposed out of the housing assembly 10, the pressing element 13 may also extend into the second shell 12 to press against an edge of the expanded portion 212 exposed out of the housing assembly 10.

Further, referring to fig. 9, in some embodiments, the pressing element 13 includes a first face 133 and a second face 134 opposite to each other, and the second face 134 faces the extension portion 212 of the flexible display screen assembly 20. In addition, the pressing member 13 is also formed with a slope 135, and the slope 135 is inclined to a side away from the second side plate 1212.

In this way, the inclined surface 135 formed on the pressing element 13 can prevent the user from scratching the fingers due to the sharp edge of the pressing element 13 during the use process, and the existence of the inclined surface 135 can also improve the aesthetic feeling of the electronic device 100 and facilitate the cleaning of dust and dirt falling on the flexible display screen assembly 20.

Further, referring to fig. 3, in some embodiments, the pressing element 13 includes a non-slip portion 136, and the non-slip portion 136 is formed on a surface of the pressing element 13 facing away from the flexible display screen assembly 20.

Thus, when the second shell 12 needs to be manually slid, a large friction force exists between the anti-slip part 136 and the fingers of the user, so that the second shell 12 can be smoothly pulled out, and the second shell 12 cannot be smoothly pulled out due to the fact that the user slips when pulling the second shell 12 is avoided. Specifically, in some embodiments, the anti-slip portion 136 may be a plurality of protrusions or a plurality of recesses formed on the pressing member 13, so that when a user needs to pull the second case 12, the hand may contact the plurality of protrusions or the plurality of recesses, thereby increasing friction force to enable the user to smoothly pull the second case.

Referring to fig. 11, in the present embodiment, the winding device 40 may be disposed in the first housing 11 or the second housing 12. The end of the expanded portion 212 remote from the flat portion 211 is wound around the winding device 40, and the winding device 40 can release the expanded portion 212 to expose the expanded portion 212 at least partially out of the housing assembly 10 while the second shell 12 moves the expanded portion 212.

Specifically, referring to the figures and drawings, the winding device 40 may include a driving assembly 41 and a winding shaft 42 connected to the driving assembly 41, an end of the expansion portion 212 remote from the flat portion 211 is wound on the winding shaft 42, and the driving assembly 41 is configured to rotate the winding shaft 42 to release the expansion portion 212 while the second housing 12 moves the expansion portion 212.

Thus, when the second shell 12 moves the expanded portion 212 to at least partially expose the housing assembly 10, the driving assembly 41 of the winding device 40 drives the reel 42 to rotate so as to release the expanded portion 212, so that the expanded portion 212 can be smoothly exposed from the housing assembly 10.

In this embodiment, the driving assembly 41 may include a motor 411 and a transmission assembly 412, the reel 42 is connected to the transmission assembly 412, and the motor 411 drives the reel 42 to rotate through the transmission assembly 412. In the illustrated embodiment, the transmission assembly 412 is a gear assembly, and the spool 42 is formed with teeth that mesh with the gear assembly, which is connected to a motor shaft of the motor 411. It is understood that, in some embodiments, the transmission assembly 412 may also be a transmission structure such as a belt transmission assembly or a chain transmission assembly, and is not limited herein.

Of course, in some embodiments, the drive assembly 41 may also be a torsion spring. Further, it will be appreciated that in some embodiments, the drive assembly 41 may also be capable of driving the second housing 12 to move relative to the first housing 11 while driving rotation of the spool 42 to release the expanded portion 212.

Next, the operation principle of the electronic device 100 according to the present embodiment will be described.

As described above, the electronic device 100 is capable of switching between the narrow screen mode and the wide screen mode. In the states shown in fig. 1, 2, and 6, the electronic apparatus 100 is in the narrow screen mode, and in the states shown in fig. 3, 4, and 7, the electronic apparatus 100 is in the wide screen state. When in the narrow screen mode, the first shell 11 and the second shell 12 cooperate to form the housing assembly 10 of the electronic device 100, the flat portion 211 of the flexible display screen 21 is hidden from the housing assembly 10, the extension portion 212 is hidden in the housing assembly 10, and the pressing member 13 presses against at least part of the edge of the flat portion 211. At this time, the area of the display area of the electronic device 100 is small, which is convenient for the user to carry.

When a user needs a large display area, the second housing 12 can be driven by the driving assembly 41 or by human power to slide towards a side away from the first housing 11, the guide shaft 30 moves along with the second housing 12, so that the extension portion 212 wound on the guide shaft 30 gradually follows the movement, and the winding device 40 also releases the extension portion 212, so that the extension portion 212 is gradually exposed from the housing assembly 10, so that the flat portion 211 and the extension portion 212 exposed from the housing assembly 10 jointly form the display area of the electronic device 100, and thus, the area of the exposed portion of the flexible display screen 21 from the housing assembly 10 is large, and at this time, the area of the display area is large, which is convenient for the user to operate to improve the operation experience of the user. During the process that the extension portion 212 is gradually exposed from the inside of the housing assembly 10, the pressing member 13 connected to the second housing 12 may press against the edge of the extension portion 212 exposed from the inside of the housing assembly 10 (as shown in fig. 3 and 8) to fix the extension portion 212 in a direction perpendicular to the flat portion 211 (i.e., in the thickness direction of the flexible display panel assembly 20), thereby preventing the extension portion 212 from being bent and wrinkled in the thickness direction of the flexible display panel assembly 20, so that the extension portion 212 can be unfolded flatly.

It can be understood that when it is required to switch from the wide screen mode to the narrow screen mode, the second housing 12 is driven to slide toward the side of the first housing 11 by the driving assembly 41 or by human power, so that the second housing 12 and the guide shaft 30 gradually release the extension portion 212, the rolling device 40 gradually rolls up the extension portion 212, so that the extension portion 212 is gradually hidden in the housing assembly 10, when the first housing 11 and the second housing 12 are fitted together, the extension portion 212 is completely hidden in the housing assembly 10, and the electronic device 100 returns to the narrow screen mode (i.e., moves from the state shown in fig. 3 to the state shown in fig. 1).

In summary, the electronic device 100 of the present embodiment includes a housing assembly 10 and a flexible display screen assembly 20. The housing assembly 10 includes a first housing 11, a second housing 12, and a pressing member 13, the first housing 11 is slidably connected to the second housing 12, and the pressing member 13 is connected to the second housing 12. The flexible display screen assembly 20 includes a flat portion 211 exposed from the housing assembly 10 and an extension portion 212 capable of being hidden in the housing assembly 10, wherein the flat portion 211 is connected to the first housing 11, and the second housing 12 is capable of sliding relative to the first housing 11 to bring the extension portion 212 at least partially exposed from the housing assembly 10. Wherein, when the extension portion 212 is at least partially exposed from the housing assembly 10, the pressing piece 13 presses the edge of the extension portion 212 exposed from the housing assembly 10.

In summary, in the electronic device 100 according to the embodiment of the present application, when the second shell 12 carries the extension portion 212 to be exposed from the housing assembly 10, the pressing member 13 can press the edge of the extension portion 212 exposed from the housing assembly 10, so as to limit the movement of the extension portion 212 in the direction perpendicular to the flat portion 211 of the flexible display panel assembly 20 (i.e., the thickness direction of the flexible display panel assembly 20). In this manner, when the flexible display panel assembly 20 is expanded, the existence of the pressing member 13 can prevent the expansion portion 212 from being bent and wrinkled in the thickness direction of the flexible display panel assembly 20, so that the expansion portion 212 can be kept unfolded flat.
