In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not in themselves indicate a relationship between the various embodiments and/or settings discussed. In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.

Referring to fig. 1 to 4, the embodiment of the present application provides a mobile terminal 100, where the mobile terminal 100 includes a first housing 11, a second housing 12, a flexible display 20, and a thrust mechanism 30. The second housing 12 is connected to the first housing 11 through a rotation shaft 13 and both are rotatable about the rotation shaft 13. The flexible display screen 20 includes a first display area 21, a second display area 22 and a third display area 23, the third display area 23 is located between the first display area 21 and the second display area 22, the first display area 21 is connected with the first housing 11, the second display area 22 is connected with the second housing 12, and the third display area 23 is located at the rotating shaft 13.

The mobile terminal 100 is capable of switching between a folded state (as shown in fig. 4) in which the first display area 21 and the second display area 22 are opposite or opposite to each other, and an unfolded state (as shown in fig. 1). The pushing mechanism 30 is disposed on the first housing 11, and the pushing mechanism 30 is located at an end of the first display area 21 away from the third display area 23 during or after the mobile terminal 100 is switched from the folded state to the unfolded state, and the pushing mechanism 30 is capable of applying a pushing force to the first display area 21 in a direction in which the first display area 21 is away from the third display area 23.

In this context, the folded state refers to a state in which the first housing 11 and the second housing 12 are rotated to be stacked together with respect to the rotation shaft 13, and the unfolded state refers to a state in which the first housing 11 and the second housing 12 are rotated to be flush with respect to the rotation shaft 13.

It can be understood that, in the related foldable mobile phone, since the materials used for the screen are all flexible materials, when the mobile phone is used for a long time or is in a bending state for a long time, the phenomenon that deformation cannot be completely recovered to cause crease occurs easily, for example, the mobile phone with an inner folding screen is easy to generate a dent, and the mobile phone with an outer folding screen is easy to generate arching.

In the mobile terminal 100 of the embodiment of the present application, the first housing 11 is provided with the pushing mechanism 30, and the pushing mechanism 30 can apply pushing force to the first display area 21 in a direction in which the first display area 21 is away from the third display area 23 during or after the mobile terminal 100 is switched from the folded state to the unfolded state. In this way, when the mobile terminal 100 is switched from the folded state to the unfolded state, if the flexible display 20 is deformed and cannot be completely restored to cause the arching or sagging phenomenon, the thrust mechanism 30 can apply a thrust to the first display area 21 to restore the flexible display 20 to be flat, and remove the crease.

In the present embodiment, the "direction in which the first display area 21 is away from the third display area 23" refers to a direction in which one end of the first display area 21 away from the third display area 23 is directed, that is, an extending direction in which the first display area 21 is away from the third display area 23.

Referring to fig. 4 and 5, in one embodiment, the mobile terminal 100 is an inwardly folded type mobile terminal, in which case, the folded state is a state in which both the first and

second housings

11 and 12 are rotated upward with respect to the rotation shaft 13 to be stacked together and the first and

second display regions

21 and 22 are opposite (see fig. 4), that is, a state in which the first and

second housings

11 and 12 are rotated upward along the rotation shaft 13 to approach and move to a limit position in fig. 5, in which the first, second and

third display regions

21, 22 and 23 of the flexible display 20 are substantially hidden between the first and

second housings

11 and 12, the first and

second display regions

21 and 22 are disposed opposite, and the first and

second housings

11 and 12 can protect the flexible display 20 while the mobile terminal 100 is small in size and convenient to carry.

The unfolded state is a state when the second housing 12 and the first housing 11 are rotated upward to be flush with each other (see fig. 5), and in the unfolded state, the first display area 21, the second display area 22 and the third display area 23 of the flexible display 20 together form a display part of the mobile terminal 100, so that the display area of the mobile terminal 100 is larger, and a better display effect is provided for a user.

Referring to fig. 5 and 6, in another embodiment, the mobile terminal 100 is an out-folded type terminal, in which case, the folded state is a state in which the first housing 11 and the second housing 12 are stacked together by rotating down relative to each other and the first display area 21 and the second display area 22 are back to back (as shown in fig. 6), that is, a state in which the first housing 11 and the second housing 12 are rotated down along the rotation axis 13 to approach and move to the extreme position in fig. 5, in which the first display area 21, the second display area 22 and the third display area 23 of the flexible display 20 are completely exposed outside the first housing 11 and the second housing 12, the first display area 21 and the second display area 22 are disposed opposite to each other, and at least one of the first display area 21, the second display area 22 and the third display area 23 can be used for display, and the mobile terminal 100 is small in size and easy to carry.

It will be appreciated that since the flexible display 20 may include different material layers, for example, the flexible display 20 may be stacked by flexible material layers such as polarizers, display layers, and optical adhesive layers, the flexible material layers may be dislocated whether the mobile terminal 100 is folded in or out. When used for a long time or in a folded state for a long time, after being unfolded to an unfolded state, the third display area 23 of the flexible display screen 20 may not be timely restored due to deformation, so that an arch or a dent is inevitably generated, for example, an inward folding may cause a dent, and an outward folding may cause an arch. In this embodiment, in the process of switching from the folded state to the unfolded state or after switching to the unfolded state, the thrust mechanism 30 disposed on the first housing 11 may apply a thrust to the first display area 21 along the extending direction of the flexible display screen 20, so as to gradually restore the flexible display screen 20 to be flat, and further gradually eliminate arching or recessing of the flexible display screen 20, so as to effectively avoid the occurrence of creases on the flexible display screen 20.

It will be appreciated that the first display area 21 and the second display area 22 may be adhered to the first housing 11 and the second housing 12 respectively through adhesive layers such as pressure sensitive adhesive, when the mobile terminal 100 is folded, each flexible layer of the flexible display 20 may generate a slight dislocation, and the dislocation of the flexible layer after long-term use may not be recovered in time to cause the mobile terminal 100 to generate an arching or recessing phenomenon during long-term use, and the purpose of the present application is to apply a pushing force to the first display area 21 so that the dislocation of the flexible layer gradually disappears to eliminate the arching or recessing.

The mobile terminal 100 of the present application may be folded up and down, or folded left and right, and the specific folding manner is not limited, so as to meet the requirements.

Referring to fig. 2 and 3, in some embodiments, the thrust mechanism 30 includes a supporting member 31 and a driving device 32, the driving device 32 is connected to the supporting member 31, and the supporting member 31 is slidably connected to the first housing 11.

The driving device 32 can drive the abutting piece 31 to abut the first display area 21 to apply a pushing force to the first display area 21 during or after the mobile terminal 100 is switched from the folded state to the unfolded state.

In this way, if the flexible display 20 is arched or concave during or after the mobile terminal 100 is switched from the folded state to the unfolded state, the driving device 32 may apply a driving force to the supporting member 31 to push the supporting member 31 to support the first display area 21, and further apply a pushing force to the first display area 21, so that the portion where the arch or concave occurs due to the dislocation is gradually unfolded, so that the flexible display 20 is restored to be flat, and the crease is eliminated.

Specifically, in such an embodiment, the thrust mechanism 30 may include only the abutment 31 and the drive device 32. The driving device 32 may drive the supporting member 31 to move through a motor and a rack-and-pinion transmission, or may drive the supporting member 31 to move through a lead screw nut, and of course, the driving device 32 may be a linear motor, and may directly drive the supporting member 31 to move through the motor. The driving device 32 pushes the abutting piece 31 to move along the direction that the first display area 21 is far away from the third display area 23, the abutting piece 31 can directly abut against the first display area 21 to apply thrust to the first display area 21, so that the first display area 21 is always far away from the third display area 23, the first display area 21 can drag the third display area 23, and folds, arching or depressions of the third display area 23 are eliminated, so that the flexible display screen 20 is restored to be flat.

Referring to fig. 3, in further embodiments, the thrust mechanism 30 further includes a push rod 33 and an elastic member 34, the push rod 33 is connected to the driving device 32, the elastic member 34 is disposed between the push rod 33 and the supporting member 31, and two ends of the elastic member 34 respectively support the supporting member 31 and the push rod 33.

In the folded state, the elastic member 34 is in a natural state, and the driving device 32 can drive the abutting member 31 to abut against the first display area 21 through the push rod 33 and the elastic member 34 to compress the elastic member 34, thereby applying a pushing force to the first display area 21 during or after the mobile terminal 100 is switched from the folded state to the unfolded state.

In this way, when the mobile terminal 100 is switched to the unfolded state, the driving device 32 pushes the push rod 33, the push rod 33 pushes the elastic member 34, and the elastic member 34 is compressed to apply a reverse acting force to the supporting member 31 so as to apply a pushing force to the first display area 21, so that the first display area 21 can pull the third display area 23, further the flexible display screen 20 is restored to be flat, and the crease is eliminated.

Specifically, in such an embodiment, the pushing mechanism 30 includes the push rod 33, the elastic member 34, and the driving device 32, so that the elastic member 34 may serve as a buffer member, and avoid the driving device 32 and the push rod 33 from being pushed too much, which may cause damage to the flexible display screen 20. In the folded state, the elastic member 34 is in a natural state, which is understood to be a state in which the elastic member 34 is neither compressed nor elongated, and is not elastically deformed. When the elastic member 34 is compressed by an external force and is in a compressed state, the elastic member 34 transmits its own pressure to the abutting member 31 and the push rod 33, which abut on both ends. Of course, it will be appreciated that when the push rod 33 pushes against the elastic member 34, the elastic member 34 may transmit pressure to the abutment 31 as an intermediate member.

In one example, the mobile terminal 100 is a folder-type terminal, and the third display area 23 is easily recessed with respect to the first and

second display areas

21 and 22 after a long period of use. During or after the mobile terminal 100 is switched from the folded state to the unfolded state, the driving device 32 drives the push rod 33 to push the elastic member 34, the elastic member 34 is elastically deformed under the pressure of the push rod 33, the elastic member 34 further drives the abutting member 31, and the abutting member 31 abuts against the first display area 21 to pull the third display area 23, so that the recess of the third display area 23 is eliminated.

In another example, the mobile terminal 100 is a folder type terminal, and after a long time use, the third display area 23 is easily arched with respect to the first and

second display areas

21 and 22. During or after the mobile terminal 100 is switched from the folded state to the unfolded state, the driving device 32 drives the push rod 33 to push the elastic member 34, the elastic member 34 is elastically deformed under the pressure of the push rod 33, the elastic member 34 further drives the abutting member 31, and the abutting member 31 abuts against the first display area 21 to pull the third display area 23, so that arching of the third display area 23 is eliminated.

It will be appreciated that in some embodiments, the thrust mechanism 30 may also include only the elastic member 34, and two ends of the elastic member 34 respectively abut against the first display area 21 and the first housing 11.

In this case, the elastic member 34 is in a compressed state to apply a pushing force to the first display area 21 in a direction in which the first display area 21 is away from the third display area 23 when in both the expanded state and the folded state.

In this way, the elastic member 34 has a certain compression amount during installation, so that the elastic member 34 can push the first display area 21 away from the third display area 23 in a direction away from the first display area 21, so that the flexible display 20 is kept flat and folds are eliminated.

In particular, in such an embodiment, the thrust mechanism 30 comprises only the elastic member 34, so that the elastic member 34 alone performs the task of applying thrust to the first display area 21, avoiding the problem of excessive components. The two ends of the elastic member 34 can directly abut against the first display area 21 and the first housing 11 to push the first display area 21 away from the first housing 11, thereby eliminating the crease.

In one example, when the mobile terminal 100 is a folder-type terminal, the third display area 23 is recessed with respect to the first and

second display areas

21 and 22 after a long period of use. When the mobile terminal 100 is in the folded state or is switched to the unfolded state, the elastic member 34 is in the compressed state to apply a pushing force to the first display area 21 so that the flexible display screen is kept flat.

In the embodiment of the present application, the specific material of the elastic member 34 is not limited, and the elastic member 34 may be a spring, a silica gel, or other elastic element, so as to meet different requirements.

Referring to fig. 2, in some embodiments, the flexible display 20 further includes a support plate 28, where the support plate 28 is connected to the first housing 11 and the second housing 12, the support plate 28 is used for supporting the first display area 21, the second display area 22 and the third display area 23, and a first bending portion 291 that bends towards the side where the first housing 11 is located is formed on a portion of the support plate 28 corresponding to the first display area 21.

During or after the mobile terminal 100 is switched from the folded state to the unfolded state, the pushing force mechanism 30 can apply a force to the first bending portion 291 to apply a pushing force to the first display area 21.

In this way, the supporting plate 28 can be used as a bearing structure of the flexible display screen 20, and the first bending portion can bear the acting force from the thrust mechanism 30, so that the supporting plate 28 can drive the flexible display screen 20 to restore to be flat, arching or recessing is avoided, and the existence of the first bending portion 291 can avoid that thrust is directly acted on the display layer of the first display area 21.

Specifically, the material of the support plate 28 is typically a rigid, high modulus material such as steel sheet, titanium alloy, or the like. The support plate 28 carries the flexible display 20, and the support plate 28 and other material layers of the flexible display 20 may be bonded to each other by pressure-sensitive adhesive, and the support plate 28 may be bonded to the first housing 11 and the second housing 12 by pressure-sensitive adhesive. When eliminating the crease, arch or depression of the flexible display screen 20, the pushing mechanism 30 may directly apply a pushing force to the supporting board 28 through the first bending portion 291, and the supporting board 28 may drive the flexible layer of the whole flexible display screen 20 to slowly creep and expand, so as to eliminate the crease of the whole flexible display screen 20.

It will be appreciated that in the embodiments of the present application, the pushing force applied by the pushing force mechanism 30 may be kept applied all the time or may be withdrawn after only waiting for the flexible display 20 to be flat after being applied for a period of time, so as to avoid the influence on the service life caused by long-term under-pushing force state of the flexible display 20, and also save electric energy.

In addition, the first bending portion 291 is bent toward the side of the first housing 11, so that the thrust mechanism 30 can directly act on the first bending portion 291 instead of the display portion of the first display area 21, and the structure is more reliable. The first bending portion 291 is located at an edge of the first display area 21 away from the third display area 23, and applies a force to the first bending portion 291, thereby transmitting the force to the first display area 21, and eliminating arching or sagging.

Referring to fig. 2, in some embodiments, the support plate 28 includes a first support portion 281, a second support portion 282 and a third support portion 283, the third support portion 283 is located between the first support portion 281 and the second support portion 282, the first support portion 281 is connected to the first display area 21 and is used for supporting the first display area 21, the second support portion 282 is connected to the second display area 22 and is used for supporting the second display area 22, the third support portion 283 is located at the rotating shaft 13, the third support portion 283 is bendable, the third support portion 283 is connected to the third display area 23 and is used for forming the third display area 23, and a first bending portion 291 is formed at an end of the first support portion 281 away from the third support portion 283.

As such, the first support portion 281 supports the first display area 21, the second support portion 282 supports the second display area 22, and the third support portion 283 supports the third display area 23, so that the entire support plate 28 can carry and protect the respective areas of the flexible display 20. The third supporting portion 283 bends to drive the third display area 23 to bend, so as to realize the folding function.

In the above embodiment, the thrust mechanism 30 applies thrust only to the first display area 21, and it is understood that in other embodiments, the thrust mechanism 30 may apply thrust to the second display area 22 at the same time, that is, the thrust mechanism 30 may also apply thrust to the first display area 21 and thrust to the second display area 22, and the present invention is not limited thereto.

Further, referring to fig. 2, in some embodiments, the third supporting portion 283 has a via array 2831 formed thereon.

In this manner, the through hole array 2831 on the third supporting part 283 has a movable margin, and when the mobile terminal 100 is in the folded state, the through hole array 2831 is unfolded, so that the mobile terminal 100 can be smoothly folded and unfolded, avoiding impeding the normal folding of the flexible display screen 20.

In addition, it is understood that, during the repeated folding process of the mobile terminal 100, the first supporting portion 281 and the second supporting portion 282 may drive the first display area 21 and the second display area 22 to face each other or face each other, and the third supporting portion 283 and the third display area 23 need to be folded multiple times. The third supporting portion 283 is formed with a through hole array 2831 to ensure that the through hole array 2831 is stretched during the folding process, so as to avoid the breakage of the third supporting portion 283 caused by excessive rigidity.

Referring to fig. 2, in some embodiments, the support plate 28 further includes a second bending portion 292, the second bending portion 292 is connected to an end of the second supporting portion 282 away from the third supporting portion 283, the second bending portion 292 is bent towards a side of the second housing 12 opposite to the second supporting portion 282 and is stacked on the second supporting portion 282, the mobile terminal 100 further includes a driving chip 40, the driving chip 40 is disposed on the second bending portion 292, and the driving chip 40 is electrically connected to the flexible display 20.

In this way, the driving chip 40 may be disposed on the second bending portion 292, and the second bending portion 292 stacked on the second supporting portion 282 may make a portion for supporting the driving chip 40 thicker, so as to effectively improve the impact resistance of the driving chip 40.

Specifically, the driving chip 40 may be an IC chip (Integrated Circuit Chip), the driving chip 40 may be connected to the display area of the flexible display screen 20 through a flexible circuit board in a binding manner, and the driving chip 40 is used for driving the flexible display screen 20 to display.

Referring to fig. 7, in some embodiments, the flexible display 20 includes a support plate 28, the support plate 28 is connected to the first housing 11 and the second housing 12, the support plate 28 is used for supporting the first display area 21, the second display area 22 and the third display area 23, the support plate 28 is bent towards a side where the first housing 11 and the second housing 12 are located to form a third bending portion 293 and a fourth bending portion 294, the third bending portion 293 and the fourth bending portion 294 are symmetrically arranged and extend along an arrangement direction of the first display area 21, the second display area 22 and the third display area 23, the first housing 11 and the second housing 12 are both formed with a first limiting groove 14 and a second limiting groove 15, the third bending portion 293 extends into the first limiting groove 14, and the fourth bending portion 294 extends into the second limiting groove 15.

In this way, the third bending portion 293 and the fourth bending portion 294 are respectively clamped on the first limiting groove 14 and the second limiting groove 15, so that the flexible display screen 20 can be tightly fixed on the first casing 11 and the second casing 12, and the flexible display screen 20 is prevented from being skewed or generating dislocation when the mobile terminal 100 falls.

It will be appreciated that the mobile terminal 100 may have a rectangular block shape such that the flexible display 20 has a rectangular shape on the first and

second housings
