Referring to fig. 2 to 5, 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 the tensioning structure 30 for placing the electronic device 100 and other electronic components of the electronic device 100, such as a motherboard, a battery, etc. The first housing 11 may protect other components mounted in the mounting cavity 111. The first housing 11 includes a top plate 112, and an upper surface of the top plate 112 is fixedly coupled to the flat portion 21 of the flexible display 20 assembly to support the flat portion 21.

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 slidable relative to the first housing 11 so as to be at least partially received within the mounting cavity 111. Referring to fig. 3, the second housing 12 includes a frame 121 and a supporting plate 122, and the frame 121 is slidably connected to the body of the first housing 11. The support plate 122 is fixedly connected to the frame 121 and slidably connected to the top plate 112 of the first housing 11. The support plate 122 slides relative to the top plate 112 when the second housing 12 slides relative to the first housing 11. It is understood that, in the present embodiment, when the second housing 12 is slid to the side where the first housing 11 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 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. 3 to 5, in the present embodiment, the flexible display 20 includes a flat portion 21 and an expansion portion 22. The flat portion 21 is exposed outside the housing assembly 10, and the flat portion 21 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 expansion part 22 can be hidden in the housing assembly 10, one end of the expansion part 22 is connected with the flat part 21, the other end is fixedly connected with the first shell 11, the middle part of the expansion part 22 is sequentially wound on the second shell 12 and the tension member 31 of the tension structure 30, and the expansion part 22 is at least partially accommodated in the second shell 12. Specifically, the expanded portion 22 is wound around the first tension pulley 40 and the second tension pulley 50 at the intermediate portion thereof. That is, one end of the expanded portion 22 is connected to the flat portion 21, and the other end thereof passes through the first tension roller 40 and the second tension roller 50 provided on the second housing 12 in sequence, passes through the tension member 31 of the tension structure 30 again, and is then fixedly connected to the first housing 11.

When the second shell 12 slides relative to the first shell 11 away from the first shell 11, the second shell 12 can drive the expansion portion 22 to at least partially expand out of the housing assembly 10, so as to form the display portion 221 of the electronic device 100 together with the expansion portion 21.

Specifically, referring to fig. 3 to 5, in the embodiment of the present application, the expansion portion 22 includes a display portion 221 and a connecting member 222, the display portion 221 is connected to the flat portion 21, a middle portion of the display portion 221 is wound around the first tensioning wheel 40 disposed on the second shell 12, one end of the connecting member 222 is fixedly connected to the display portion 221, the other end of the connecting member 222 is fixedly connected to the first shell 11, and a middle portion of the connecting member 222 is sequentially wound around the second tensioning wheel 50 and the tensioning member 31 of the tensioning structure 30. That is, in the embodiment of the present application, one end of the connecting member 222 is fixedly connected to the display portion 221, and the other end thereof is fixedly connected to the first housing 11 after sequentially passing around the second tension pulley 50 and the tension member 31 of the tension structure 30. Thus, the display part 221 of the expansion part 22 does not need to be wound on the tension member 31, and the service life of the flexible display screen 20 can be prolonged.

It should be noted that, in this document, the other end of the connecting member 222 is fixedly connected to the first housing 11, which means that the other end of the connecting member 222 is fixed relative to the first housing 11 without relative movement. Specifically, in the embodiment of the present application, the other end of the connecting member 222 may be directly fixedly connected to the first shell 11 or fixedly connected to the first shell 11 through other components, or the other end of the connecting member 222 may be fixedly connected to the middle portion of the connecting member 222 after bypassing the tensioning member 31, and the specific arrangement manner is not limited, and only needs that the other end of the connecting member 22 is relatively fixed to the first shell 11.

Further, in the embodiment of the present application, the first tensioning wheel 40 and the second tensioning wheel 50 may be pulleys, which constitute a movable pulley assembly, and further cooperate with the tensioning structure 30 to enable the expansion to be maintained in a tensioned state.

In the illustrated embodiment, the first tension wheel 40 and the first tension wheel 40 are each a pulley rotatably provided on the second housing 12, and an intermediate portion of the expanded portion 22 is wound around the pulley. Thus, when the second shell 12 drives the expansion part 22 and the connecting piece 222 to move, the pulleys roll correspondingly, rolling friction exists between the two, the friction force is small, and compared with a mode of directly fixing the first tensioning wheel 40 on the second shell 12, the rotation can prevent the connecting piece 222 from being abraded greatly and even clamping the connecting piece 222 due to overlarge friction force between the connecting piece 222 and the first tensioning wheel 40. Of course, in some embodiments, the first tensioning wheel 40 may be directly fixed to the first shell 11, and it is only necessary to make the surface of the first tensioning wheel 40 smooth without generating a large friction force with the connecting member 222 during the manufacturing process.

In addition, in the present embodiment, the flat portion 21 and the top plate 112 may be fixed by a double-sided tape or an optical tape. It is understood that in other embodiments, other fixing methods are also used, for example, magnetic attraction can be used for fixing, specifically, in such embodiments, a magnetic element can be attached to the back of the flat portion 21, and the top plate 112 can 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 and 4, when only the flat portion 21 of the flexible display screen 20 is exposed from the housing assembly 10, the display area of the electronic device 100 is small, and at this time, the first shell 11 and the second shell 12 are combined together to form a smaller housing assembly 10, and the electronic device 100 is in the narrow screen mode (as shown in fig. 1 and 4). In this case, the second housing 12 may be partially housed in the mounting cavity 111 of the first housing 11 or may be entirely housed in the mounting cavity 111.

Referring to fig. 2 and 5, 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 22 to at least partially expand outside the housing assembly 10 through the first tensioning wheel 40 to adjust the display area of the electronic device 100, so that the exposed extension portion 22 and the exposed extension portion 21 jointly form a display portion 221 of the electronic device 100, and the display area is large. 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 22 is maximized and the display area is also maximized (see fig. 5), and at this time, the electronic apparatus 100 is in the wide screen mode.

It can be understood that, in the embodiment of the present application, in the wide screen mode, the second shell 12 can slide relative to the first shell 11 to a side close to the first shell 11, and the second shell 12 drives the extension portion 22 to at least partially retract into the housing assembly 10 through the second tensioning wheel 50, so as to reduce the display area of the electronic device 100, i.e., move from the state shown in fig. 5 to the state shown in fig. 4. That is, in the embodiment of the present application, the second shell 12 can slide relative to the first shell 11 to drive the extension portion 22 to at least partially extend out of the housing assembly 10 or retract into the housing assembly 10, so as to adjust the display area of the electronic device 100, and the electronic device 100 can be switched between the narrow-screen mode and the wide-screen mode.

Furthermore, in the illustrated embodiment, the second shell 12 carries the extension portion 22 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 22 is only partially exposed from the housing assembly 10. It is understood that in some embodiments, the extension portion 22 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. 4 to 6, in an embodiment of the present application, the tensioning structure 30 includes a tensioning member 31 and an adjusting member 32, the adjusting member 32 is connected to the tensioning member 31, the tensioning member 31 is mounted on the first shell 11, one end of the expanding portion 22 is connected to the flat portion 21, the other end of the expanding portion 22 is fixedly connected to the first shell 11, a middle portion of the expanding portion 22 is sequentially wound on the second shell 12 and the tensioning member 31, and the adjusting member 32 is configured to drive the tensioning member 31 to move relative to the first shell 11 to drive the expanding portion 22 to move, so as to tension the expanding portion 22.

Thus, the middle portion of the expansion portion 22 is sequentially wound around the second shell 12 and the tension member 31, and the adjustment member 32 can drive the tension member 31 to move relative to the first shell 11, so that the tension member 31 drives the expansion portion 22 to move to tension the expansion portion 22. In this way, the tensioning member 31 of the tensioning structure 30 can be driven by the adjusting member 32 to move so as to tension the expansion portion 22 of the flexible display screen 20, so that when the second shell 12 drives the expansion portion 22 to move, the expansion portion 22 can maintain a tensioned state so as to prevent the flexible display screen 20 from arching, thereby avoiding affecting the display effect and smooth movement, and simultaneously preventing the housing assembly 10 from scratching the screen.

It can be understood that, when assembling and maintaining the electronic device 100, due to the assembling error and the manufacturing error of each flexible display screen 20, the flexible display screen 20 is easily kept in a tensioned state during the installation of the flexible display screen 20, in which case the flexible display screen 20 may arch during the movement, which may cause the moving part to smoothly set the scratch on the flexible display screen 20. Therefore, after the tensioning structure 30 is provided, in the process of installing the flexible display screen 20, the tensioning member 31 can be driven by the adjusting member 32 to move, so that the flexible display screen 20 can be in a tensioned state when different flexible display screens 20 are installed, and the flexible display screen 20 is prevented from arching to influence the movement and damage to the flexible display screen 20 is avoided.

In the illustrated embodiment, the display portion 221 of the expanded portion 22 is wound around the first tension pulley 40 on the second housing 12, and the connecting member 222 is wound around the second tension pulley 50 and the tension member 31 in this order. It is understood that in other embodiments, the expanding portion 22 may be formed by sequentially winding the first tensioning wheel 40, the second tensioning wheel 50 and the tensioning member 31 as a whole, and the specific description is not limited herein.

Referring to fig. 4 to 7, the tensioning member 31 includes a first connecting portion 311 and a second connecting portion 312, the second connecting portion 312 is connected to one side of the first connecting portion 311 and protrudes from the first connecting portion 311, that is, the overall tensioning member 31 is substantially "L" shaped.

The first connecting portion 311 is formed with a through hole 3111, and the expanded portion 22 is formed through the through hole 3111 such that an intermediate portion of the expanded portion 22 is wound around the tension member 31.

Specifically, in the illustrated embodiment, the connecting member 222 of the extension portion 22 is threaded through and around the tension member 31. Thus, when the tension member 31 is driven by the adjusting member 32, the tension member 31 can move the connecting member 222 of the expansion portion 22 to tension the expansion portion 22.

It can be understood that in the embodiment of the present application, the through hole 3111 on the first connection portion 311 and the surface contacting with the expansion portion 22 are smooth surfaces, so that a large friction between the connection member 222 and the first connection portion 311 can be prevented, a large damage to the connection member 222 is avoided, the service life is reduced, and even the connection member 222 is directly broken.

Of course, it can also be understood that, in order to prevent the connecting member 222 from being pulled apart and reduce friction between the connecting member 222 and the second shell 12 and the tensioning member 31, in the embodiment of the present application, the connecting member 222 has a superior tensile property, and the surface of the connecting member 222 is smooth. Specifically, in some embodiments, the connecting element 222 may be a pulling rope, and the pulling rope may be made of polyimide film (PI material) or stainless steel material, and of course, the type of the connecting element 222 is not limited to the pulling rope, and may also be other elements, such as a flexible belt. In addition, in order to stabilize the movement of the expansion part 22, the number of the tension structures 30 and the connectors 222 is two, and the two tension structures 30 and the two connectors 222 are respectively disposed at two symmetrical sides of the housing assembly 10.

Referring to fig. 3, in some embodiments, in order to enable the connection member 222 to stably and effectively tension the display part 221 of the expansion part 22, the connection member 222 may be connected to the display part 221 through the connection plate 23. Thus, the connecting surface between the connecting plate 23 and the display part 221 has a large area, and the entire display part 221 can be tensioned by the connecting plate 23 by providing the small connecting piece 222.

Referring to fig. 3 to 7, in the embodiment of the present application, the first housing 11 is formed with a mounting post 114, the tension member 31 is formed with a mounting slot 3112, the mounting slot 3112 is slidably engaged with the mounting post 114, and the mounting post 114 slides in the mounting slot 3112 when the adjustment member 32 drives the tension member 31 to move relative to the first housing 11.

Thus, the tension member 31 can be positioned and mounted by the engagement of the mounting post 114 and the mounting slot 3112, and the sliding engagement of the mounting slot 3112 with the mounting post 114 also enables the tension member 31 to move relative to the first housing 11 upon actuation of the adjustment member 32.

It will be appreciated that in this embodiment, the direction of movement of the tension member 31 is parallel to the direction of sliding of the second housing 12, so that the manner of movement of the tension member 31 is easily achieved. Of course, in some embodiments, the movement direction of the tension member 31 and the sliding direction of the second shell 12 may also have a certain angle, as long as the tension member 31 can keep the expansion portion 22 in tension. It will be appreciated that the cooperation of the mounting slot 3112 and the mounting post 114 can guide the movement of the tension member 31 such that the tension member 31 can only move in the mounting slot 3112, ensuring stability of the movement.

Further, referring to fig. 3, in such an embodiment, the mounting post 114 is formed with a mounting hole 115, the adjusting member 32 is mounted in the mounting hole 115, and the adjusting member 32 can move along the axial direction of the mounting hole 115 to abut against and drive the tensioning member 31 to move relative to the first shell 11.

Specifically, in such embodiments, the mounting holes 115 may be threaded holes and the adjustment members 32 may be threaded fasteners. Thus, the adjusting member 32 is threadedly coupled to the mounting hole 115, and when it is desired to drive the tension member 31 to move, the adjusting member 32 can be screwed to move the adjusting member 32 in the axial direction of the mounting hole 115 so as to abut against the second connecting portion 312 of the tension member 31 to drive the tension member 31 to move, and the fitting of the mounting post 114 and the mounting groove 3112 can guide the movement of the tension member 31. That is, in the embodiment of the present application, the adjusting member 32 is movable in the axial direction of the mounting hole 115 to abut against the second connecting portion 312 and apply a force to the second connecting portion 312, thereby driving the tensioning member 31 to move relative to the first housing 11, and thus tensioning the expansion portion 22. It will be appreciated that the threaded connection of the adjustment member 32 to the mounting hole 115 improves the accuracy of adjustment of the tensioning member 31, and in particular that precise adjustment of the tensioning member 31 can be achieved with a smaller pitch to avoid the risk of the extension portion 22 being too tensioned and thus being snapped off due to an excessively large pitch. Specifically, in the embodiment of the present application, the pitch of the adjusting member 32 may preferably range from 0.35mm to 0.5 mm.

Referring to fig. 4 and 5, in an embodiment, the adjusting member 32 may include a column portion 322 and a head portion 321 connected to the column portion 322, the diameter of the head portion 321 is larger than that of the column portion 322, the mounting hole 115 is opened along the sliding direction of the second shell 12, and the adjusting member 32 can move along the axial direction of the mounting hole 115 to make the column portion 322 abut against the second connecting portion 312 and apply a force to the second connecting portion 312, so as to drive the tensioning member 31 to move along the direction parallel to the sliding direction of the second shell 12, and further tension the expansion portion 22.

Therefore, the tensioning member 31 can be abutted by the movement of the column part 322 of the adjusting member 32, so that the tensioning member 31 is driven to move along the direction parallel to the sliding direction of the second shell 12, that is, the parallel movement of the column part 322 can be converted into the parallel movement of the tensioning member 31, and the structure is simple and convenient to realize. In such embodiments, the adjustment member 32 may be a threaded fastener such as a screw or bolt.

Referring to fig. 6, in another embodiment, the adjusting member 32 includes a column portion 322 and a head portion 321 connected to the column portion 322, the diameter of the head portion 321 is larger than that of the column portion 322, the mounting hole 115 is opened in a direction perpendicular to the flat portion 21, and the adjusting member 32 can move along an axial direction of the mounting hole 115 to make the head portion 321 abut against the second connecting portion 312 and apply a force to the second connecting portion 312.

In this way, the vertical movement of the head 321 of the adjusting member 32 in the direction perpendicular to the flat portion 21 can be utilized to abut against the tensioning member 31, so that the tensioning member 31 is driven to move in the direction parallel to the sliding direction of the second housing 12, thereby achieving the conversion of the vertical movement of the adjusting member 32 into the parallel movement of the tensioning member 31. In such embodiments, the adjustment member 32 may also be a threaded fastener such as a screw or bolt.

It should be noted that the diameter of the head portion 321 is larger than that of the pillar portion 322, and it is understood that the circumscribed circle of the head portion 321 is larger than the outer circumference of the pillar portion 322, and the head portion 321 covers the pillar portion 322. For example, in the illustrated embodiment, the pillar portion 322 has a cylindrical shape, the head portion 321 may have a cylindrical shape or a truncated cone shape, and the diameter of the head portion 321 at any position is larger than that of the pillar portion 322. Of course, when the head 321 has another shape, the diameter of the circumscribed circle of the head 321 is larger than that of the pillar 321.

Further, referring to fig. 6, in such an embodiment, the head portion 321 may be formed with a first guiding inclined surface 3113, the first guiding inclined surface 3113 is inclined from the top of the head portion 321 to a side where the mounting hole 115 is located, and the first guiding inclined surface 3113 abuts against the second connecting portion 312.

In this way, during the movement of the head portion 321 in the direction perpendicular to the flat portion 21, the first guiding inclined surface 3113 abuts against the second connecting portion 312, and since the first guiding inclined surface 3113 is inclined toward the side where the mounting hole 115 is located, the diameter of the head portion 321 from bottom to top is gradually increased, and therefore, the head portion 321 gradually drives the tensioning member 31 to move in the direction perpendicular to the adjusting member 32 during the movement, so as to drive the expansion portion 22 to move to tension the expansion portion 22.

In addition, referring to fig. 6 again, in some embodiments, the second connection portion 312 is formed with a second guiding inclined surface 3211, the second guiding inclined surface 3211 inclines from the top of the second connection portion 312 to the side of the mounting groove 3112, and the head portion 321 abuts against the second guiding inclined surface 3211.

Thus, during the movement of the head portion 321 in the direction perpendicular to the flat portion 21, the head portion 321 abuts against the second guiding inclined surface 3211, and since the second guiding inclined surface 3211 is inclined toward the side where the mounting groove 3112 is located, that is, from the second connection portion 312 toward the side where the first connection portion 311 is located, the head portion 321 gradually drives the tensioning member 31 to move in the direction perpendicular to the adjusting member 32 during the movement, so as to drive the expansion portion 22 to move to tension the expansion portion 22.

Referring to fig. 3 to 5, in some embodiments, the first shell 11 may be formed with a tension portion 113, a middle portion of the expansion portion 22 is sequentially wound around the second shell 12, the tension portion 113 and the tension member 31, and the tension portion 113 is located at a middle position of the second shell 12. The first tension pulley 40, the second tension pulley 50 and the tension part 113 constitute a pulley assembly so that the link 222 can be maintained in a tensioned state regardless of the position of the second housing 12.

Specifically, when the second housing 12 is relatively far away from the first housing 11, the tensioning portion 113 is fixed, the second tensioning wheel 50 on the second housing 12 gradually releases the connecting member 222, so as to gradually release the extension portion 22, the extension portion 22 is gradually unfolded out of the housing assembly 10 under the action of the first tensioning wheel 40, and the moving strokes of the second housing 12 and the extension portion 22 are the same, so that the second housing 12 can both tension the connecting member 222 during the process of gradually unfolding the extension portion 22 out of the housing assembly 10, so as to tension the flexible display screen 20.

When the second shell 12 is relatively close to the first shell 11, the first tension wheel 40 gradually releases the expansion part 22, the tension part 113 is also fixed, and the second tension wheel 50 drives the connecting piece 222 to move towards the side where the first shell 11 is located, so as to drive the expansion part 22 to gradually retract into the shell assembly 10, in such a process, the moving distance of the second shell 12 and the moving stroke of the expansion part 22 are also the same, so that in the process of retracting and expanding the expansion part 22 into the shell assembly 10, due to the existence of the first tension wheel 40, the second tension wheel 50 and the tension part 113, no matter where the second shell 12 is located, the connecting piece 222 can be kept tensioned, so as to tension the expansion part 22.

It can be understood that, during the assembly process of the electronic device 100, one end of the connecting member 222 can be fixedly connected to the first housing 11 after sequentially winding the second end of the second housing 12, the tensioning portion 113 and the adjusting member 32, and during the assembly process, the tensioning member 31 can be driven by the adjusting member 32 to move to ensure that the expansion portion 22 is in the tensioned state, so that the adjustment function of the adjusting member 32 can eliminate the installation error of the flexible display 20 and perform matching adjustment on different flexible display 20, thereby ensuring that the expansion portion 22 can be in the tensioned state.

In the illustrated embodiment, in order to keep the connection member 222 in tension regardless of the movement of the second case 12, the tension part 113 is located at an intermediate position of the second case 12. It will be appreciated that in other embodiments, instead of the tensioning portion 113, the tensioning member 31 may be arranged at an intermediate position of the second housing 12 around the portion where the connecting member 222 is arranged, which is at the intermediate position of the second housing 12 regardless of the movement of the second housing 12, so that tensioning of the connecting member 222 and thus of the expansion portion 22 is also achieved.

In summary, the electronic device 100 of the embodiment of the present application includes a housing assembly 10, a flexible display screen 20, and a tensioning structure 30. The housing assembly 10 includes a first housing 11 and a second housing 12 slidably coupled. The flexible display 20 includes a flat portion 21 and an expanded portion 22 connected to each other, the flat portion 21 is connected to the first casing 11, the flat portion 21 is exposed outside the casing assembly 10, the expanded portion 22 can be hidden inside the casing assembly 10, and the second casing 12 can slide relative to the first casing 11 to drive the expanded portion 22 to at least partially expand out of the casing assembly 10 or retract into the casing assembly 10. The tensioning structure 30 comprises a tensioning member 31 and an adjusting member 32, the tensioning member 31 is installed on the first shell 11, one end of the expansion part 22 is connected with the flat part 21, the other end of the expansion part is fixedly connected with the first shell 11, the middle part of the expansion part 22 is sequentially wound on the second shell 12 and the tensioning member 31, and the adjusting member 32 is used for driving the tensioning member 31 to move relative to the first shell 11 so as to drive the expansion part 22 to move, so that the expansion part 22 is tensioned.

In summary, in the electronic device 100 according to the embodiment of the present application, the middle portion of the expansion portion 22 is sequentially wound around the second housing 12 and the tension member 31, and the adjusting member 32 can drive the tension member 31 to move relative to the first housing 11, so that the tension member 31 drives the expansion portion 22 to move to tension the expansion portion 22. In this way, the tensioning member 31 of the tensioning structure 30 can be driven by the adjusting member 32 to move so as to tension the expansion portion 22 of the flexible display screen 20, so that when the second shell 12 drives the expansion portion 22 to move, the expansion portion 22 can maintain a tensioned state so as to prevent the flexible display screen 20 from arching, thereby avoiding affecting the display effect and smooth movement, and simultaneously preventing the housing assembly 10 from scratching the screen.
