Referring to fig. 5, the second bracket 14 is fixedly mounted on the second casing 12 and is accommodated in the second accommodating cavity 120, the second bracket 14 is also substantially rectangular, and the second bracket 14 is fixedly connected to the flexible display 20. The second bracket 14 includes an insertion portion 141 and a plurality of protrusions 142 formed on the insertion portion 141. The insertion portion 141 is configured to be engaged with the receiving cavity 1311 of the first bracket 13, the protrusions 142 may be opened along a transverse direction of the electronic device 100, and the protrusions 142 correspond to the grooves 1312 of the first bracket 13 so that the protrusions 142 can be engaged with the grooves 1312.

The second support 14 is slidably connected to the first support 13, and the second support 14 is movable relative to the first support 13. The insertion portion 141 is slidable in the housing chamber 1311 when the second bracket 14 moves relative to the first bracket 13. The plurality of grooves 1312 may be opened along the sliding direction of the second bracket 14 and arranged at intervals along the vertical direction and the sliding direction. When the insertion portion 141 slides in the receiving cavity 1311, the protrusions 142 of the second bracket 14 can slide in the grooves 1312 of the first bracket 13, and the surfaces of the grooves 1312 are flush with the surfaces of the protrusions 142. Specifically, in the present embodiment, the second bracket 14 is movable relative to the second bracket 13 to move away from or close to the first bracket 13, and the second bracket 14 can move the second housing 12 and the components (such as the main board 40 and the battery 50) accommodated in the second accommodating cavity 120 relative to the first housing 11 and the first bracket 13 and the driving assembly 30 mounted on the first bracket 13.

It can be understood that in the present embodiment, the insertion portion 141 is engaged with the receiving cavity 1311, and the groove 1312 and the protrusion 142 are engaged, so that the sliding of the second bracket 14 relative to the first bracket 13 is more stable and reliable. Meanwhile, the surface of the groove 1312 and the surface of the protrusion 142 are flush, so that a height difference is not formed on the upper surfaces of the second bracket 14 and the first bracket 13 when the second bracket slides relative to the first bracket 13, thereby ensuring the flatness of the electronic device 100. It should be noted that, in this document, "flush" may be understood as the same height, or may be understood as the difference in height between the two is within the manufacturing error and the assembling error.

In the present embodiment, the first bracket 13 is formed with a groove 1312, and the insertion portion 141 of the second bracket 14 is formed with a projection 142. It will be appreciated that in other embodiments, the first bracket 13 may be formed with a projection and the second bracket 14 may be formed with a recess. Or the first bracket 13 may be formed with a protrusion and a groove at the same time, the insertion portion may also be formed with a groove and a protrusion at the same time, the protrusion on the first bracket 13 may be matched with the groove on the insertion portion, the groove on the first bracket 13 may be matched with the protrusion on the insertion portion 141, and the specific arrangement manner is not limited herein.

Referring to fig. 3, in the present embodiment, the flexible display 20 includes a first portion 21 and a second portion 22, the first portion 21 is exposed from the housing assembly 10, and the second portion 22 is hidden in the housing assembly 10.

Referring to fig. 5 to 8, the first portion 21 is located above the second frame 14, the first portion 21 covers the second frame 14 and is fixedly connected to the second frame 14, and the first portion 21 is further connected to the driving assembly 30.

The second portion 22 is hidden in the first receiving cavity 110 of the first housing 11 and connected with the driving assembly 30. Both the first portion 21 and the second portion 22 can be driven by the driving assembly 30, so that the second portion 22 is at least partially exposed and hidden from the housing assembly 10.

In this way, when the area of the display area of the electronic device 100 needs to be enlarged, the driving assembly 30 can drive the second portion 22 of the flexible display screen 20 to be exposed from the housing assembly 10, so that the first portion 21 and the exposed second portion 22 jointly form the display area of the electronic device 100, and the display area is enlarged.

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.

In this embodiment, the first portion 21 and the protrusion 142 on the second bracket 14 can be fixed by a double-sided tape. It will be appreciated that in other embodiments, other fixing means may be used, for example, magnetic means may be used for fixing, and in such embodiments, specifically, a magnetic element may be attached to the back of the first portion 21, and the protrusion 142 on the second bracket 14 may be made of a magnetic material, and the two are magnetically attracted together, and the specific arrangement is not limited herein.

In addition, in the present embodiment, in a normal state, only the first portion 21 of the flexible display 20 is usually exposed from the housing assembly 10, and at this time, only the first portion 21 is used for displaying, and the display area of the electronic device 100 is small.

When the display area of the electronic device 100 needs to be enlarged, the driving assembly 30 can drive the first portion 21 and the second portion 22 to move, so that the second portion 22 is at least partially exposed from the housing assembly 10. At this time, the first portion 21 and the second portion 22 exposed from the inside of the housing assembly 10 together constitute a display area of the electronic device 100, and the display area becomes large. It can be understood that, in this case, if the display area of the electronic device 100 needs to be reduced, the second portion 22 can be retracted into the first accommodating cavity 110 only by driving the first portion 21 and the second portion 22 to move in opposite directions through the driving assembly 30, so that the second portion 22 is hidden in the housing assembly 10, and thus the display area of the electronic device 100 becomes smaller and is convenient for a user to carry. In this way, the driving assembly 30 can move the first portion 21 and the second portion 22, so that the electronic device 100 can be switched between a large screen and a small screen in a limited space.

It will be appreciated that in the present embodiment, the first portion 21 is fixedly connected to the second frame 14, and the first portion 21 moves while the second frame 14 moves relative to the first frame 13. The first support 13 may support the first portion 21 to prevent a collapse phenomenon from occurring when the flexible display panel 20 is pressed.

In addition, referring to fig. 6 to 9, when the second portion 22 is exposed from the first receiving cavity 110 of the first housing 11, the exposed portion is located above the first bracket 13, and the exposed portion of the second portion 22 is substantially attached to the surface of the first bracket 13 where the groove 1312 is formed, so that the first bracket 13 can support the exposed portion of the second portion 22.

It should be noted that, in this document, "fit" may be understood as the contact between the two without affecting the sliding between the two, or may be understood as the gap between the two is within the assembling error range. That is, the second portion 22 is movable relative to the second support 14 by the drive means 31.

In addition, referring to fig. 10 and 11, in the present embodiment, since the surface of the protrusion 142 is flush with the surface of the groove 1312, when the second portion 22 is exposed to the housing assembly 10, there is no height difference between the portion of the second portion 22 exposed from the housing assembly 10 and the first portion 21, or the height difference is within a tolerance range and does not affect the user experience. Thus, it is ensured that the display area of the electronic device 100 does not have the problem of unevenness.

In addition, it can be understood that, in the present embodiment, the number of the grooves 1312 and the protrusions 142 is set to ensure that the user does not collapse significantly when touching or pressing the display area of the electronic device 100, that is, when the user presses the display area (i.e., the portion of the first portion 21 and the second portion 22 exposed from the housing assembly 10) of the electronic device 100, the display area does not collapse significantly to ensure the operation experience, and the specific number of the grooves 1312 and the protrusions 142 can be set according to the actual situation.

Referring to fig. 5, 10 and 11, in the present embodiment, the driving assembly 30 includes a driving device 31 and a transmission assembly 32. The driving device 31 may be a power device such as a motor, for example, a stepping motor. The motor may include a motor body and a motor shaft that is coupled to the drive assembly 32.

Referring to fig. 5 and 10, the number of the transmission assemblies 32 is two, the two transmission assemblies 32 are respectively located at two symmetrical sides of the housing assembly 10, and both of the two transmission assemblies 32 are connected to the flexible display 20. Specifically, two transmission assemblies 32 are respectively installed at both sides of the first bracket 13 that are perpendicular to the sliding direction of the second bracket 14. The motor comprises two motor shafts arranged on two sides of the motor body, and the two transmission assemblies 32 are respectively connected with the two motor shafts. In this way, the two transmission assemblies 32 synchronously drive the first portion 21 and the second portion 22 of the flexible display screen 20, so that the smoothness and reliability of the movement of the flexible display screen 20 can be ensured. Of course, in some embodiments, the number of the transmission assemblies 32 may also be 1 or more than 2, and is not limited herein.

In the present embodiment, the specific structures of the two transmission assemblies 32 are substantially the same, and in order to avoid redundancy, only the specific structure of one of the transmission assemblies 32 will be described below.

Referring to fig. 5, 10 and 11, the transmission assembly 32 may include a transmission belt 321, a first transmission wheel 322, a second transmission wheel 323, a first connection member 324 and a second connection member 325, a gear set 326 and a driving shaft 327.

The conveyor belt 321 has two ends connected to the first portion 21 and the second portion 22, respectively. The driving device 31 is used for driving the conveyor belt 321 to move so as to drive the second portion 22 to move, so that the second portion 22 is at least partially exposed or hidden in the housing assembly 10.

Specifically, the first driving wheel 322 and the second driving wheel 323 are spaced apart from each other, the transmission belt 321 is wound around the first driving wheel 322 and the second driving wheel 323 to tension the transmission belt 321, the driving device 31 is connected to the first driving wheel 322 through the gear set 326 and the driving shaft 327, the driving device 31 is configured to drive the first driving wheel 322 to rotate, so as to drive the transmission belt 321 to move to drive the first portion 21 and the second portion 22 to move, so that the second portion 22 is at least partially exposed or hidden from the housing assembly 10.

In the present embodiment, the conveyor belt 321 has a first tooth 3211, the first drive wheel 322 has a second tooth 3221, the second drive wheel 323 has a third tooth 3231, and both the second tooth 3221 and the third tooth 3231 mesh with the first tooth 3211. Thus, when the driving device 31 drives the first driving wheel 322 to rotate, the first driving wheel 322 can drive the belt 321 to move, and the belt 321 drives the second driving wheel 323 to rotate, so that the belt 321 can move circularly, and the first portion 21 and the second portion 22 of the flexible display screen 20 are driven to move, so that the second portion 22 is at least partially exposed or hidden in the housing assembly 10.

Specifically, referring to fig. 3, fig. 4, and fig. 6 to fig. 9, in the present embodiment, the driving device 31 may be configured to drive the first portion 21 to move between the first position a and the second position B, and drive the second portion 22 to move while driving the first portion 21 to move from the first position a to the second position B, so that the second portion 22 is at least partially exposed from the housing assembly 10.

When the first portion 21 is located at the first position a, the second bracket 14 is connected to the first bracket 13 in a matching manner, and when the first portion 21 moves from the first position a to the second position B, the first portion 21 drives the second bracket 14 to move, so that the second bracket 14 is relatively far away from the first bracket 13.

It can be understood that, referring to fig. 3, fig. 6 and fig. 8, when the first portion 21 is located at the first position a, the area of the display area of the electronic device 100 is the smallest, the second bracket 14 and the first bracket 13 are cooperatively connected together, the insertion portion 141 of the second bracket 14 is substantially completely inserted into the receiving cavity 1311 of the first bracket 13, and the size of the electronic device 100 is the smallest and is convenient for a user to carry. Referring to fig. 4, 7 and 9, when the first portion 21 moves from the first position a to the second position B, the display area of the electronic device 100 gradually increases, and when the second portion 22 moves to the second position B, the area of the electronic device 100 is the largest.

Referring to fig. 5, 10 and 11, the first connecting member 324 and the second connecting member 325 are disposed on the conveyor belt 321 at an interval, the first connecting member 324 is fixedly connected to the first portion 21 of the flexible display screen 20 and the conveyor belt 321, the second connecting member 325 is fixedly connected to the second portion 22 of the flexible display screen 20 and the conveyor belt 321, and the conveyor belt 321 drives the first portion 21 to move through the first connecting member 324 and drives the second portion 22 to move through the second connecting member 325.

Specifically, the first link 324 is provided on a portion of the conveyor belt 321 on one side of the first drive wheel 322, and the second link 325 is provided on a portion of the conveyor belt 322 on the other side of the first drive wheel 322. That is, the first link 324 and the second link 325 are located at opposite sides of the first driving wheel 322. The first connector 324 is disposed on the conveyor belt 321 and connected to an end of the first portion 21 close to the second portion 22, and the second connector 325 is disposed on the conveyor belt 321 and connected to an end of the second portion 22 far from the first portion 21.

It is understood that in the present embodiment, the first portion 21 of the flexible display screen 20 is connected to the conveyor belt 321 through the first connector 324, the second portion 22 is connected to the conveyor belt 321 through the second connector 325, the overall shape of the flexible display screen 20 is substantially U-shaped, and the second portion 22 of the flexible display screen 20 passes around the first driving wheel 322 like the conveyor belt 321.

In general, the entire circumference of the conveyor belt 321 is constant during the movement, and the length between the conveyor belts 321 between the first connecting member 324 and the second connecting member 325 is also constant. Therefore, when the driving assembly 30 drives the conveyor belt 321 to move through the first driving wheel 322, the first connecting member 324 moves to drive the first portion 21 to move, and the second connecting piece 325 also moves to drive the second portion 22 to follow the movement, it can be understood that, in the whole moving process, since the overall distance between the first connecting member 324 and the second connecting member 325 is not changed, the second portion 22 does not wrinkle in the moving process, so that the second portion 22 can be smoothly exposed from the housing assembly 10 without bending the flexible display screen 20 to cause unevenness of the display area of the electronic device 100.

Specifically, referring to fig. 8 and 9, in the present embodiment, the first link 324 and the second link 325 can be engaged with each other within the inter-tooth space of the first tooth portion 3211, so that the teeth of the first tooth portion 3211 can limit the movement of the first link 324 and the second link 325, thereby enabling the first link 324 and the second link 325 to be stably mounted on the conveyor belt 321. In addition, the first and

second connection members

324 and 325 may be connected to the first and

second parts

21 and 22, respectively, by an adhesive such as a double-sided tape or an optical tape.

The gear set 326 may be a reduction gearbox assembly or a gear set 326 composed of a plurality of gears engaged with each other, the gear set 326 is connected with the driving device 31 and the first driving wheel 322, and the gear set 326 is used for changing the transmission ratio between the driving device 31 and the first driving wheel 322, namely changing the rotation speed ratio between the driving device 31 and the first driving wheel 322. Specifically, in the present embodiment, the gear set 326 is connected to the driving device 31, the driving shaft 327 connects the gear set 326 and the first driving wheel 322, and the gear set 326 drives the first driving wheel 322 to rotate through the driving shaft. It will be appreciated that in some embodiments, the transmission assembly 32 may not have a drive shaft, but rather directly engage the gear set 326 with the first drive wheel 322, and the drive device 31 directly drives the first drive wheel 322 to rotate via the gear set 326.

In the present embodiment, the first tooth portion 3211 is formed on the conveyor belt 321 to mesh with the second tooth portion 3221 of the first transmission wheel 322 and the third tooth portion 3231 of the second transmission wheel 323, thereby realizing a transmission function.

When a user needs a larger display area, the two driving devices 31 drive the first driving wheel 322 to rotate through the gear set 326 and the driving shaft 327, so as to drive the conveying belt 321 to move to drive the first portion 21 to move from the first position a to the second position B through the first connecting member 324 and the second connecting member 325, and drive the second portion 22 to be at least partially exposed from the housing assembly 10 while driving the first portion 21 to move, so that the first portion 21 and the second portion 22 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 20 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. In this case, the second housing 12 is gradually distanced from the first housing 11, and the second bracket 14 is gradually distanced from the first bracket 13. It can be understood that, referring to fig. 4, fig. 7 and fig. 9, when the first portion 21 moves to the second position B, the area of the display area of the electronic device 100 is the largest, and at this time, the electronic device 100 is in the large-screen state (i.e., moves from the state shown in fig. 3 to the state shown in fig. 4).

When the large screen state needs to be switched to the small screen state, the driving device 31 is only required to drive the first transmission gear to rotate reversely to drive the first portion 21 to move from the second position B to the first position a, and drive the second portion 22 to gradually hide the second portion 22 in the housing assembly 10, when the first portion 21 moves to the first position a, the first housing 11 and the second housing 12 are fitted together, the first bracket 13 and the second bracket 14 are completely fitted together, the driving device 31 stops operating, and the electronic device 100 returns to the small screen state (i.e., moves from the state shown in fig. 4 to the state shown in fig. 3).

In summary, the electronic device 100 of the embodiment of the present application includes a housing assembly 10, a flexible display 20, and a driving group 30, and the flexible display 20 includes a first portion 21 exposed from the housing assembly 10 and a second portion 22 hidden in the housing assembly 10. The driving assembly 30 includes a driving device 31 and a transmission assembly 32, the driving device 31 is mounted on the housing assembly 10, the transmission assembly 32 is connected to the driving device 31, the transmission assembly 32 includes a conveyor belt 321, two ends of the conveyor belt 321 are respectively connected to the first portion 21 and the second portion 22, the driving device 31 is configured to drive the conveyor belt 321 to move so as to drive the second portion 22 to move, so that the second portion 22 is at least partially exposed or hidden in the housing assembly 10.

In summary, in the electronic device 100 of the embodiment of the present application, when the area of the display area of the electronic device 100 needs to be enlarged, the driving device 31 and the conveyor belt 321 can drive the second portion 22 of the flexible display 20 to be exposed from the housing assembly 10, so that the first portion 21 and the exposed second portion 22 jointly form the display area of the electronic device 100, and the display area is enlarged. In this way, the display area of the electronic device 100 can be expanded by only driving the second portion 22 to be at least partially exposed from the housing assembly 10 through the driving device 31 and the conveyor belt 321. Meanwhile, the driving device 31 and the conveyor belt 321 can also drive the second portion 22 to move so that the second portion 22 is hidden in the housing assembly 10, thereby reducing the display area of the electronic device 100. This allows the electronic device 10 to switch between large and small screens in a limited space.
