It can be appreciated that in the present embodiment, the insertion portion 1221 is engaged with the receiving cavity 1122, and the groove 1123 is engaged with the protrusion 1222, so that the sliding of the second bracket 122 relative to the first bracket 112 is more stable and reliable. Meanwhile, the surface of the recess 1123 and the surface of the protrusion 1222 are flush so that a height difference is not formed on the upper surfaces of the second bracket 122 and the first bracket 112 when the second bracket slides relative to the first bracket, thereby ensuring 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 112 is formed with a groove 1123, and the insertion portion 1221 of the second bracket 122 is formed with a projection 1222. It will be appreciated that in other embodiments, the first leg 112 may be formed with a protrusion and the second leg 122 may be formed with a recess.

Referring to fig. 3, 4, 7 and 8, 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 can be hidden in the housing assembly 10.

Referring to fig. 7 to 10, the first portion 21 is located above the second bracket 122, and the first portion 21 covers the second bracket 122 and is fixedly connected to the second bracket 122.

The second portion 22 can be hidden in the first receiving cavity 110 of the first shell 111 and fixedly connected with the flexible belt 31 of the transmission assembly 30. The first portion 21 can be carried by the second housing 12 and the second portion 22 can be carried by the flexible belt 31 of the transmission assembly 30, such that the second portion 22 is at least partially exposed from the housing assembly 10 or hidden in the housing assembly 10.

Thus, when the area of the display area of the electronic device 100 needs to be enlarged, the transmission 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 is noted that, in the present disclosure, unless otherwise expressly specified or limited, 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 via 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 1222 of the second bracket 122 may be fixed by a double-sided tape. It is understood that in other embodiments, other fixing methods are also used, for example, magnetic fixing can be used, specifically, in such embodiments, a magnetic element can be attached to the back of the first portion 21, and the protrusion 1222 on the second bracket 122 can 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 second housing 12 is relatively far away from the first housing 11, and the second housing 12 drives the flexible belt 31 of the transmission assembly 30 to move, so as to drive the second portion 22 to move, so that the second portion 22 is at least partially exposed out of 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 housing 12 is relatively close to the first housing 11, the second housing 12 drives the flexible belt 31 of the transmission assembly 30 to move reversely, so as to drive the second portion 22 to move reversely, and the second portion 22 can be retracted into the first accommodating cavity 110, so that the second portion 22 is hidden in the housing assembly 10, and thus the display area of the electronic device 100 is reduced, which is convenient for the user to carry. This may allow the electronic device 100 to switch between a large screen and a small screen in a limited space.

It can be understood that, in the present embodiment, the first portion 21 is fixedly connected to the second support 122, and when the second support 122 moves relative to the first support 112, the first portion 21 moves along with the second support 122, and the first support 112 can support the first portion 21, so as to prevent the flexible display panel 20 from collapsing when 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 shell 111, the exposed portion is located above the first support 112, and the exposed portion of the second portion 22 is substantially attached to the surface of the first support 112 forming the groove 1123, so that the first support 112 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 can move relative to the second bracket 122 under the driving of the flexible belt 31 of the transmission assembly 30.

In addition, referring to fig. 10 and 11, in the present embodiment, since the surface of the protrusion 1222 and the surface of the groove 1123 are flush, 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 an error range without affecting 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 1123 and the protrusions 1222 can be 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 1123 and the protrusions 1222 can be set according to the actual situation.

Referring to fig. 5 to 7, in the present embodiment, the guide shaft 60 is disposed on the mounting portion 1224 of the first bracket 112 and can rotate relative to the first bracket 112. The intermediate portion of the second portion 22 is wound around the guide shaft 60.

In this manner, the guide shaft 60 can guide the movement of the second portion 22, thereby enabling the second portion 22 to be smoothly deployed to be exposed from the housing assembly 10 and to be smoothly hidden from the housing assembly 10.

In addition, the presence of the guide shaft 60 may maintain the form of the second portion 22, thereby preventing the second portion 22 from being significantly deformed during movement, which may reduce the lifetime of the flexible display 20.

In particular, in the present embodiment, the guide shaft 60 may make the second portion 22 substantially U-shaped, so that the second portion 22 at both sides of the guide shaft 60 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 60, as long as the flexible belt 31 of the transmission assembly 30 can move the second portion 22 to expose the housing assembly 10.

Referring to fig. 5 and fig. 7 to 12, in the present embodiment, the number of the transmission assemblies 30 is two, two transmission assemblies 30 are respectively located at two symmetrical sides of the housing assembly 10, and both transmission assemblies 30 are connected to the second portion 22 of the flexible display panel 20.

Specifically, two transmission assemblies 30 are respectively installed at both sides of the first bracket 112 that are perpendicular to the sliding direction of the second bracket 122. Of course, in some embodiments, the number of the transmission assemblies 30 may also be 1 or more than 2, and is not limited herein, for example, when the number of the transmission assemblies 30 is 1, the transmission assemblies 30 may be disposed at the middle position of the first bracket 112.

In the present embodiment, the specific structures of the two transmission assemblies 30 are substantially the same, and in order to avoid redundancy, only the specific structure of one of the transmission assemblies 30 will be described below.

Referring to fig. 7 to 12, the driving assembly 30 may include a flexible belt 31, a first driving wheel 32, a second driving wheel 33, a first connecting member 34 and a second connecting member 35.

One end of the flexible belt 31 is fixedly connected to the second support 122 of the second housing 12, and the other end is connected to the second portion 22 of the flexible display 20, specifically, in the illustrated embodiment, an intermediate portion of the second portion 22 is wound around the guide shaft 60, and an end of the second portion 22 away from the first portion 21 is fixedly connected to the flexible belt 31 after being wound around the guide shaft 60. Thus, when the second housing 12 moves relative to the first housing 11, the second housing 12 can drive the flexible strip 31 to move, and the flexible strip 31 drives 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 32 and the second driving wheel 33 are rotatably disposed on the first bracket 112 of the first housing 11, the first driving wheel 32 and the second driving wheel 33 are disposed at intervals, the flexible belt 31 is in a ring shape and wound around the first driving wheel 32 and the second driving wheel 33, the first driving wheel 32 and the second driving wheel 33 tension the flexible belt 31, and the flexible belt 31 is in a track shape. Frictional resistance exists between the first driving wheel 32 and the second driving wheel 33 and the flexible belt 31, and when the second housing 12 drives the flexible belt 31 to move, the first driving wheel 32 and the second driving wheel 33 are driven to rotate by the driving belt 31 through the frictional resistance.

Referring to fig. 3 and fig. 4 as well as fig. 7 to fig. 10, in the present embodiment, the first support 112 of the first housing 11 is movable between a first position a and a second position B relative to the second support 122 of the second housing 12, when the second support 122 is located at the first position a, the second support 122 is connected to the first support 112 in a matching manner, and the second portion 22 is completely hidden in the housing assembly 10. As the second support 122 moves from the first position a to the second position B, the second support 122 gradually moves away from the first support 112, and the second support 122 moves the flexible strip 31, so that the flexible strip 31 moves the second portion 22 to at least partially expose the housing assembly 10.

It can be understood that, with reference to fig. 3, fig. 7 and fig. 9, when the second bracket 122 is located at the first position a, the area of the display area of the electronic device 100 is the smallest, the second bracket 122 and the first bracket 112 are connected together in a matching manner, the insertion portion 1221 of the second bracket 122 is substantially completely inserted into the receiving cavity 1122 of the first bracket 112, 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 10, when the second bracket 122 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 bracket 122 moves to the second position B, the area of the electronic device 100 is the largest.

Referring to fig. 5, 7 to 10, the first connecting member 34 and the second connecting member 35 are disposed on the flexible strip 31 at an interval, the first connecting member 34 is fixedly connected to the second bracket 122 and the flexible strip 31, the second connecting member 35 is fixedly connected to the second portion 22 of the flexible display 20 and the flexible strip 31, the second bracket 122 drives the flexible strip 31 to move through the first connecting member 34, and the flexible strip 31 drives the second portion 22 to move through the second connecting member 35.

Specifically, the first link 34 is provided on a portion of the flexible belt 31 on one side of the first and

second transmission wheels

32 and 33, and the second link 35 is provided on a portion of the flexible belt 31 on the other side of the first and

second transmission wheels

32 and 33. That is, the first link 34 and the second link 35 are located on opposite sides of the first driving wheel 32. The first connecting member 34 is disposed on the flexible belt 31 and connected to an end of the second housing 12 close to the first housing 11. A second connector 35 is provided on the flexible strip 31 at the end of the connecting second portion 22 remote from the first portion 21.

It is understood that in the present embodiment, the first portion 21 of the flexible display 20 is connected to the second support 122, one end of the second portion 22 is connected to the flexible belt 31 through the second connecting member 35, the overall shape of the flexible display 20 is substantially U-shaped, and the second portion 22 of the flexible display 20 passes around the first driving wheel 32 as the flexible belt 31.

As a whole, the overall circumference of the racetrack-shaped flexible band 31 is constant during movement, as is the length between the flexible bands 31 between the first connector 34 and the second connector 35. Therefore, when the second bracket 122 moves relative to the first bracket 112, the second bracket 122 drives the first connecting member 34 and the first portion 21 to move, the first connecting member 34 drives the flexible belt 31 to move, meanwhile, the second connecting member 35 also moves, and the second connecting member 35 drives the second portion 22 to also move along with the first connecting member 34 to expose the housing assembly 10 or hide the second portion in the housing assembly 10, it can be understood that, in the whole moving process, because the overall distance between the first connecting member 34 and the second connecting member 35 does not change, the second portion 22 does not wrinkle in the moving process, so that the second portion 22 can be stably exposed from the housing assembly 10 without bending the flexible display screen 20 to cause the display area of the electronic device 100 to be uneven.

Specifically, in the embodiment of the present invention, the flexible belt 31 may be an element having a certain flexibility and flexibility such as a steel rope, a cotton rope, a fishing line, and a V-belt, or the flexible belt 31 may be made of a flexible tensile material such as a PI film (polyimide film), which is not limited herein. Preferably, in order to make the flexible belt 31 have high strength and prevent the flexible belt 31 from being worn too much to cause a reduction in life span, in the embodiment of the present invention, the flexible belt 31 is preferably a steel rope.

Referring to fig. 5 and 6, in some embodiments, the driving assembly 30 may further include a screen connecting member 36, the screen connecting member 36 is fixedly connected to the second connecting member 35 and the second portion 22, and the second connecting member 35 drives the second portion 22 to move through the screen connecting member 36.

Specifically, the screen connecting member 36 is in a long strip shape, and two ends of the screen connecting member 36 are respectively connected to two second connecting members 35 disposed at two sides of the first bracket 112, that is, the screen connecting member 36 extends from one side of the first bracket 112 to the opposite side thereof, and the second portion 22 is fixedly connected to the screen connecting member 36. In this manner, the screen connecting member 36 spans substantially the entire first bracket 112 in a direction perpendicular to the sliding direction, so that the connecting area of the second portion 22 and the connecting member 323 is large, thereby enabling the screen connecting member 36 to more stably move the second portion 22. It will be appreciated that in the illustrated embodiment, the two drive assemblies 30 share a single screen attachment 36, i.e., the two second attachment members 35 disposed on opposite sides of the first frame 112 may be connected by the same screen attachment 36, and the two second attachment members 35 move in unison to drive movement of the screen attachment 36 to move the second portion 22. Of course, in other embodiments, two different screen connectors 36 may be provided for two transmission assemblies 30, and are not limited in particular.

In an embodiment of the present invention, the second housing 12 may be pulled or pushed by a user to slide the second housing 12 relative to the first housing 11 to be away from or close to the first housing 11, so that the second housing 12 can move the flexible belt 31, and the flexible belt 31 moves the second portion 22 to at least partially expose the second portion 22 to the housing assembly 10 or hide the second portion 22 in the housing assembly 10. It is understood that in other embodiments, the electronic device 100 may further include a driving assembly, and the driving assembly may include a motor and a rack-and-pinion assembly or a motor and a lead screw assembly, and the motor may drive the second housing 12 to move relative to the first housing 11 by way of a rack-and-pinion or by way of a lead screw, so that the second portion 22 is at least partially exposed to the housing assembly 10 or hidden in the housing assembly 10, which is not limited herein.

In this case, the second case 121 is gradually distant from the first case 111, and the second bracket 122 is gradually distant from the first bracket 112. It can be understood that, referring to fig. 4, 8 and 10, 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 it is required to switch from the large screen state to the small screen state, it is only necessary to push the second housing 12 in the opposite direction to move from the second position B to the first position a, so that the flexible belt 31 is driven by the first connecting member 34 to move in the opposite direction, the flexible belt 31 is driven by the second connecting member 35 to move in the opposite direction 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 shell 111 and the second shell 121 are fitted together, the first bracket 112 and the second bracket 122 are completely fitted together, 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 according to the embodiment of the present invention includes a housing assembly 10, a flexible display screen 20 and a transmission assembly 30, the housing assembly 10 includes a first housing 11 and a second housing 12 that can slide relatively, the flexible display screen 20 includes a first portion 21 exposed from the housing assembly 10 and a second portion 22 that can be hidden in the housing assembly 10, the first portion 21 is fixedly connected to the second housing 12, the transmission assembly 30 includes a flexible band 31, one end of the flexible band 31 is fixedly connected to the second housing 12, the other end of the flexible band 31 is connected to the second portion 22, when the second housing 12 moves relative to the first housing 11, the second housing 12 drives the flexible band 31 to move, so as to drive the second portion 22 to at least partially expose the housing assembly 10 or hide in the housing assembly 10.

In summary, in the electronic device 100 according to the embodiment of the invention, when the area of the display area of the electronic device 100 needs to be changed, the first housing 11 and the second housing 12 can slide relatively, so that the second housing 12 drives the flexible tape 31 to move, so that the second portion 22 is at least partially exposed out of the housing assembly 10 or at least partially hidden in the housing assembly 10, thereby changing the display area of the electronic device 10. Therefore, the flexible belt 31 can be driven by the second housing 12 to move, so as to drive the second portion 22 to be at least partially exposed from the housing assembly 10, and the display area of the electronic device 100 can be expanded, and meanwhile, the flexible belt 31 can also be driven by the second housing 12 to move, so as to drive the second portion 22 to move, so as to hide the second portion 22 in the housing assembly 10, so as to reduce the display area of the electronic device 100, and thus, the electronic device 100 can be switched between a large screen and a small screen in a limited space.
