Referring to fig. 1 to 3, in the present embodiment, the housing assembly 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are slidably connected.

In the present embodiment, the first housing 11 may have a substantially rectangular shape. The first housing 11 is formed with a mounting cavity 111. The mounting cavity 111 is used for at least partially receiving the second case 12 and a rolling device for placing the electronic device 100 and other electronic components of the electronic device 100, such as a motherboard, a battery, and the like. The first housing 11 may protect other components mounted in the mounting cavity 111. The first housing 11 includes a top plate 112 and a main body 114, the main body 114 forms the mounting cavity 111, the top plate 112 is disposed on the main body 114, and an upper surface of the top plate 112 is fixedly connected to the flexible display panel assembly 20 to support the flexible display panel assembly 20. A chute 113 is formed between the main body 114 and the top plate 112. Specifically, in the illustrated embodiment, the sliding groove 113 is formed on the main body 114, the top plate 112 is located above the sliding groove 113 and covers the sliding groove 113, and the first shell 11 is slidably connected to the second shell 12 through the sliding groove 113.

It is understood that in other embodiments, the sliding groove 113 may be formed at the bottom of the top plate 112, and is not limited in particular. The top plate 112 and the main body 114 may be integrally formed or may be separately formed.

The second housing 12 is located at one side of the first housing 11, and the second housing 12 may have a substantially rectangular shape. The second housing 12 is at least partially received within the mounting cavity 111. Referring to fig. 4, the second housing 12 includes a frame 121 and a supporting plate 122, and the frame 121 is slidably connected to the second housing 12. The frame 121 is formed with a receiving cavity 1211, and the receiving cavity 1211 is used for receiving the guide shaft 30. The supporting plate 122 is fixedly connected to the frame 121 and is engaged with the sliding slot 113 of the second housing 12. The support plate 122 slides within the slide groove 113 when the second housing 12 slides relative to the first housing 11. Specifically, when the second housing 12 slides away from the side where the first housing 11 is located, the support plate 122 slides out at least partially from the slide groove 113. It is understood that, in the present embodiment, when the second housing 12 is slid to the side where the second housing 12 is located to the limit position, the second housing 12 may be entirely or partially received in the mounting cavity 111 of the first housing 11. When the second housing 12 is slid to the side away from the first housing 11, the second housing 12 is partially slid out of the mounting cavity 111.

It is noted that in the description of the present application, such as the "first shell" and the "second shell" described above, the terms "first" and "second" are used for descriptive purposes only and are not intended to indicate that the housing assembly has only two shells, nor to imply that the first shell is more important than the second shell, or that the terms "first" and "second" are not to be interpreted as indicating or implying relative importance or to imply indicating the number of indicated technical features. 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 6, the flexible display panel assembly 20 includes a flexible display panel 21 and a flexible supporting member 22, and the flexible supporting member 22 and the flexible display panel 21 are stacked and fixedly connected along a thickness direction of the flexible display panel assembly 30.

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 first housing 11 and is at least partially fixedly connected to the top plate 112 of the first housing 11. The extension 212 can be hidden inside the housing assembly 10, and one end of the extension 212 is connected to the flat portion 211 and the other end is connected to the winding device 40. 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 112 may be fixed by a double-sided adhesive tape or an optical adhesive tape. It is understood that in other embodiments, other fixing methods 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 112 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, 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 housing 11 and the second housing 12 are combined together to form a smaller housing assembly 10, in such a case, the second housing 12 may be partially received in the mounting cavity 111 of the first housing 11 or may be completely received in the mounting cavity 111.

Referring to fig. 7 and 8, 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 extension portion 212 to be gradually exposed from the inside of the housing assembly 10, so that the exposed extension portion 212 and the exposed extension 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. 7). At this time, the electronic device 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 embodiment shown in fig. 7, 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 expansion portion 212 may also be entirely exposed from the housing assembly 10 when the electronic device 100 is in the wide-screen mode, which is not limited herein.

Referring to fig. 5, 6 and 9, in the present embodiment, the flexible supporting member 22 is stacked below the expanding portion 212, and the flexible supporting member 22 at least partially covers the expanding portion 212. The flexible support 22 serves to support the expansion portion 212, and the flexible support 22 follows the expansion portion 212 when the expansion portion 212 moves.

Referring to fig. 5, fig. 6 and fig. 9, the flexible supporting member 22 includes a main body 221 and two position-limiting portions 222, the two position-limiting portions 222 are located at two longitudinal edges of the flexible supporting member 22, i.e. two longitudinal edges of the flexible display screen assembly 20.

In this embodiment, the body 221 is stacked below the extension portion 212, the upper surface of the body 221 is connected to the extension portion 212 of the flexible display panel assembly 20, the upper surface of the top plate 112 is connected to the flat portion 211, and the upper surface of the body 221 is flush with the upper surface of the top plate 112 of the first housing 11.

Thus, when the extension portion 212 is driven by the second shell 12 to be at least partially exposed from the interior of the housing assembly 10, the upper surface of the body 221 of the flexible support member 22 is flush with the upper edge surface of the top plate 112, so that the flat portion 211 and the exposed extension portion 212 do not have an obvious height difference, and the flexible display screen 21 is relatively flat, and the flatness of the flexible display screen 21 is ensured, thereby not only improving the operation experience of a user, but also improving 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 9, in the present embodiment, the position-limiting portion 222 is used for cooperating with the supporting plate 122 of the second shell 12. Specifically, when the second housing 12 carries the extension portion 212 to be at least partially exposed from the housing assembly 10, the support plate 122 cooperates with the position-limiting portion 222 to fix the extension portion 212 in a direction perpendicular to the flat portion 211 (i.e., a thickness direction of the flexible display panel assembly 20 and a sliding direction perpendicular to the second housing 12) (see fig. 9).

Thus, when the flexible display screen assembly 20 is expanded, the existence of the supporting member and the limiting portion 222 can prevent the expansion portion 212 from being bent and folded in the direction perpendicular to the flat portion 211, so that the expansion portion 212 can be flatly unfolded, and the texture, reliability and user experience of the whole flexible display screen assembly are improved.

Referring to fig. 5 and 9, in some embodiments, the position-limiting portion 222 includes a plurality of protrusions 2222, the plurality of protrusions 2222 are disposed on the body 221, the protrusions 2222 are located on a side of the body 221 facing away from the expansion portion 212 of the flexible display 21, the plurality of protrusions 2222 are arranged at intervals along the sliding direction of the second housing 12, each protrusion 2222 is formed with a groove 2223, the groove 2223 penetrates through the entire protrusion 2222 along the sliding direction of the second housing 12, and the plurality of grooves 2223 together form a position-limiting groove 2221. When the second shell 12 carries the expanded portion 212 to be exposed from the housing assembly 10, the support plate 122 is engaged with the position-limiting groove 2221 and can slide in the position-limiting groove 2221.

It can be understood that, in this embodiment, the plurality of protrusions 2222 are disposed on the body 221 at intervals, so that the protrusions 2222 are effectively prevented from being deformed greatly when the flexible display screen assembly 20 is bent, meanwhile, when the flexible line display screen assembly 20 is bent, the protrusions 2222 corresponding to the bent portion are close to each other, and a stress main body during bending is the protrusions 2222 of the flexible support 22 rather than the flexible display screen 21, so that the service life of the flexible display screen 21 is prolonged.

Further, in some embodiments, the cross-sectional area of projection 2222 gradually decreases in a direction away from body 221. In this way, the protrusions 2222 have a wide top and narrow bottom structure so that the protrusions 2222 of the bent portion do not interfere with each other when the flexible line display panel assembly 20 is bent.

It should be noted that, since the flexible display 21 and the flexible support 22 both have a curved portion, the above-mentioned "protrusions 2222 are arranged at intervals along the sliding direction of the second shell 12" is directed to the arrangement of the protrusions 2222 when the flexible support 22 is in the flat state.

Referring to fig. 5 and 9, in this embodiment, the protrusion 2222 includes a protrusion 2224 and a bending portion 2225, the protrusion 2224 is protruded from the main body 221, the bending portion 2225 is connected to the protrusion 2224, the bending portion 2225 is bent from an end of the protrusion 2224 away from the main body 221 relative to the protrusion 2224, and the bending portion 2225, the protrusion 2224 and the main body 221 form a groove 2223.

Specifically, in the illustrated embodiment, the projection 2222 is provided at an edge position of the flexible support 22, and the bent portion 2225 is bent toward the inner side of the flexible support 22 with respect to the projection 2224. When the expansion portion 212 exposes the housing assembly 10, the protruding portion 2224 is substantially perpendicular to the body 221, and the bent portion 2225 is substantially parallel to the body 221. The grooves 2223 are open toward the inner side of the flexible support 22 so that both ends of the support plate 122 can smoothly enter the grooves 2223.

It will be appreciated that when the second housing 12 is slid relative to the first housing 11 in a direction away from the first housing 11, the support plate 122 gradually enters the grooves 2223 of the protrusions 2222 aligned in the sliding direction (i.e., moves from the position shown in fig. 5 to the position shown in fig. 9), thereby restricting the movement of the flexible support 22 and the flexible display 21 in a direction perpendicular to the flat portion 211 (i.e., in the thickness direction of the flexible display assembly 20) to avoid bending, arching, etc. of the extension portion 212 during the movement.

It should be noted that in this application, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact with each other through another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As can be seen from the above description, in the present embodiment, the position-limiting portion 222 is a position-limiting groove 2221 formed by a plurality of grooves 2223 opened by the protrusions 2222 spaced at intervals on the flexible support 22. It is understood that in other embodiments, the position-limiting portion 222 may be a position-limiting groove 2221 directly formed on the entire flexible support 22 along the sliding direction.

Of course, in some embodiments, the position-limiting portion 222 is not limited to be formed only on the flexible supporting member 22, and other structures may also be adopted, such as an elastic abutting structure, in such embodiments, the supporting plate 122 may be provided with a plurality of recesses at intervals along the sliding direction, and adjacent recesses are connected smoothly, a spring and a push rod may be fixedly disposed on the flexible display screen assembly 20, and when the supporting plate 122 moves, the push rod abuts against the recess on the supporting plate 122 under the action of the spring, so as to fix the expanding portion 212 in the direction perpendicular to the flat portion 211 (i.e. in the thickness direction of the flexible display screen assembly 20). It will be appreciated that in such an embodiment, the flexible support member 22 cannot move in the thickness direction of the flexible display screen assembly 20 because the push rods abut against the recesses, and the recesses are smoothly connected, and the push rods can be disengaged from the recesses to enter the adjacent recesses when the support member slides.

Referring to fig. 2 to 5 and 9, in the present embodiment, the guiding shaft 30 is disposed in the receiving cavity 1211 of the second shell 12 and is rotatably connected to the second shell 12, that is, the guiding shaft 30 can rotate in the receiving cavity 1211. An intermediate portion of the expanded portion 212 is provided 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 can maintain the shape 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 screen 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.

In the present embodiment, the winding device 40 may be provided at the first case 11 or the second case 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 fig. 10 and 11, 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 away 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 shell 12 drives the expansion portion 212 to move.

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 is a gear assembly, and the spool 42 has teeth formed thereon, which are engaged 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 driving 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 relative to the first housing 11 while driving rotation of the spool to release the extension 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 state shown in fig. 1 and 4, the electronic apparatus 100 is in the narrow screen mode, and in the state shown in fig. 7 and 8, 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 are matched to form the housing assembly 10 of the electronic device 100, the flat part 211 of the flexible display screen 21 is hidden from the housing assembly 10, the expanded part 212 is hidden in the housing assembly 10, and the supporting plate 122 of the second shell 12 is not matched with the limiting groove 2221 on the limiting part 222 (as shown in fig. 5). 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 component 41 or by manpower to slide towards a side far away from the first housing 11 relative to the first housing 11, the guide shaft 30 moves along with the second housing 12, so that the extension part 212 wound on the guide shaft 30 gradually moves along, and the winding device also releases the extension part 212, so that the extension part 212 is gradually exposed from the housing component 10, and the flat part 211 and the extension part 212 exposed from the housing component 10 jointly form the display area of the electronic device 100. In the process that the extension portion 212 is gradually exposed from the housing assembly 10, the support plate 122 on the second case 12 gradually enters the position-limiting groove 221 on the position-limiting portion 222 to be fitted into the position-limiting groove 2221 (as shown in fig. 9) so as 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 flatly unfolded.

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 winding device gradually winds 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 matched 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. 7 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 and a second housing 12 slidably coupled, and the second housing 12 includes a support plate 122. The flexible display screen assembly 20 includes a flat portion 211 exposed from the housing assembly 10 and an extension portion 212 hidden in the housing assembly 10, wherein the flat portion 211 is fixedly connected to the first housing 11, and the second housing 12 can slide relative to the first housing 11 to bring the extension portion 212 at least partially exposed from the housing assembly 10. The flexible display panel assembly 20 further includes a limiting portion 222, and when the second shell 12 brings the extension portion 212 to be at least partially exposed from the housing assembly 10, the supporting plate 122 cooperates with the limiting portion 222 to fix the extension portion 212 in a direction perpendicular to the flat portion 211 (i.e., in a thickness direction of the flexible display panel assembly 20).

In summary, in the housing assembly 10 and the electronic device 100 according to the embodiment of the present application, when the second housing 12 carries the extension portion 212 to be exposed from the housing assembly 10, the supporting plate 122 on the second housing 12 can cooperate with the positioning portion 222 on the extension portion 212 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). Thus, when the flexible display screen assembly 20 is expanded, the existence of the supporting piece and the limiting part 222 can prevent the expansion part 212 from being bent and folded in the thickness direction of the flexible display screen assembly 20, so that the expansion part 212 can be flatly unfolded, and the texture, the reliability and the user experience of the whole machine are improved.
