Moreover, the present application may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of brevity and clarity and do not in themselves dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

Referring to fig. 1 to 4, the present embodiment 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 pushing mechanism 30. The second housing 12 and the first housing 11 are connected by a rotating shaft 13 and are rotatable around the rotating 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 (shown in fig. 4) in which the first display area 21 and the second display area 22 are opposed or reversed, and an unfolded state (shown in fig. 1). The thrust mechanism 30 is disposed on the first housing 11, and during or after the mobile terminal 100 is switched from the folded state to the unfolded state, the thrust mechanism 30 is located at an end of the first display area 21 away from the third display area 23, and the thrust mechanism 30 can apply a thrust to the first display area 21 in a direction in which the first display area 21 is away from the third display area 23.

It should be noted that, in this document, 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 rotating 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 each other with respect to the rotating shaft 13.

It can be understood that, in the related foldable mobile phone, since the screen is made of a flexible material, when the foldable mobile phone is used for a long time or is in a bent state for a long time, the foldable mobile phone is prone to deformation and incomplete recovery, which may cause a crease phenomenon, for example, a concave phenomenon is prone to occur in a mobile phone with an inner folding screen, and an arch phenomenon is prone to occur in a mobile phone with an outer folding screen.

In the mobile terminal 100 of the embodiment of the present application, the thrust mechanism 30 is provided on the first housing 11, and the thrust mechanism 30 can apply a thrust 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, and the flexible display 20 is arched or dented, the pushing mechanism 30 can apply a pushing force to the first display area 21 to restore the flexible display 20 to be flat and eliminate 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 the direction in which the end of the first display area 21 away from the third display area 23 faces, that is, the extending direction of the first display area 21 away from the third display area 23.

Referring to fig. 4 and 5, in one embodiment, the mobile terminal 100 is a foldable mobile terminal, in which the folded state is a state in which the first housing 11 and the second housing 12 are folded and stacked upward relative to the rotating shaft 13 and the first display area 21 and the second display area 22 are opposite to each other (see fig. 4), that is, a state in which the mobile terminal 100 is located when the first housing 11 and the second housing 12 in fig. 5 are rotated upward along the rotating shaft 13 to be close to each other and move to an extreme position, in which the first display area 21, the second display area 22, and the third display area 23 of the flexible display 20 are substantially hidden between the first housing 11 and the second housing 12 and the first display area 21 and the second display area 22 are opposite to each other, the first housing 11 and the second housing 12 can protect the flexible display 20, and 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 portion of the mobile terminal 100, and the display area of the mobile terminal 100 is larger, so as to provide a better display effect for a user.

Referring to fig. 5 and 6, in another embodiment, the mobile terminal 100 is a folded-out terminal, in which the folded state is a state in which the first housing 11 and the second housing 12 are folded together by rotating them relatively and rotating them downward and the first display area 21 and the second display area 22 are opposite to each other (as in fig. 6), that is, a state in which the mobile terminal 100 is located when the first housing 11 and the second housing 12 in fig. 5 are rotated downward along the rotating shaft 13 to be close to and move to an extreme position, 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 opposite to each other, at least one of the first display area 21, the second display area 22, and the third display area 23 may be used for displaying in this state, and the mobile terminal 100 has a small volume, is convenient for carrying.

It is understood that, since the flexible display 20 may include different material layers, for example, the flexible display 20 may be formed by stacking flexible material layers such as a polarizer, a display layer, and an optical adhesive layer, the flexible material layer may generate a phenomenon of dislocation regardless of the inward folding or the outward folding of the mobile terminal 100. When the display device is used for a long time or is folded for a long time, after the display device is unfolded to the unfolded state, the third display area 23 of the flexible display 20 may be deformed and not restored in time, so that the problem of arching or sinking inevitably occurs, for example, the inward folding may cause the sinking, and the outward folding may cause the arching. In the embodiment of the present application, in the process of switching from the folded state to the unfolded state or after switching to the unfolded state, the pushing mechanism 30 disposed on the first housing 11 may apply a pushing force to the first display area 21 along the extending direction of the flexible display 20, so as to gradually restore the flexible display 20 to be flat, thereby gradually eliminating the arching or sinking of the flexible display 20, and effectively avoiding the flexible display 20 from having a crease.

It can be understood that the first display area 21 and the second display area 22 can be adhered to the first housing 11 and the second housing 12 respectively through an adhesive layer such as a pressure sensitive adhesive, when the mobile terminal 100 is folded, each flexible layer of the flexible display 20 can slightly dislocate, and just because the dislocation of the flexible layer cannot be recovered in time after long-time use, the phenomenon of arching or sinking of the mobile terminal 100 can occur after long-time use, but the purpose of the present application is to apply a thrust to the first display area 21 so that the dislocated flexible layer gradually disappears to eliminate the arching or sinking.

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, and the requirements may be satisfied.

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.

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

In this way, in the process of switching the mobile terminal 100 from the folded state to the unfolded state or after switching to the unfolded state, if the flexible display screen 20 is arched or sunken, the driving device 32 may apply a driving force to the abutting member 31 to push the abutting member 31 to abut against the first display area 21, and further apply a thrust to the first display area 21, so that the arched or sunken portion is gradually unfolded due to the dislocation, and the flexible display screen 20 is restored to be flat and the crease is eliminated.

In particular, in such an embodiment, the thrust mechanism 30 may comprise only the abutment 31 and the drive means 32. The driving device 32 can drive the abutting piece 31 to move through the transmission of the motor and the gear rack, or can drive the abutting piece 31 to move through a screw nut, of course, the driving device 32 can be a linear motor, and can directly drive the abutting piece 31 to move through the motor. The driving device 32 pushes the abutting member 31 to move along the direction in which the first display area 21 is far from the third display area 23, and the abutting member 31 can directly abut against the first display area 21 to apply a pushing force to the first display area 21, so that the first display area 21 is always far from the third display area 23, and the first display area 21 can pull the third display area 23, thereby eliminating the crease, arch camber or dent of the third display area 23, and enabling the flexible display screen 20 to return to be flat.

Referring to fig. 3, in some 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 abutting member 31, and two ends of the elastic member 34 abut against the abutting member 31 and the push rod 33, respectively.

In the folded state, the elastic member 34 is in a natural state, and during or after the mobile terminal 100 is switched from the folded state to the unfolded state, 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, so as to apply a pushing force to the first display area 21.

Thus, 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, after being compressed, applies a reverse acting force to the abutting member 31 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, and 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 pushing rod 33, the elastic member 34 and the driving device 32, so that the elastic member 34 can serve as a buffer to prevent the driving device 32 and the pushing rod 33 from pushing too much, which may cause damage to the flexible display 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 extended and is not elastically deformed. When the elastic element 34 is compressed by an external force and is in a compressed state, the elastic element 34 transmits the self pressure to the abutting element 31 and the push rod 33 which are abutted at the two ends. Of course, it is understood that when the push rod 33 pushes the elastic member 34, the elastic member 34 can act as an intermediate member to transmit the pressure to the holding member 31.

In one example, the mobile terminal 100 is a folder type terminal, and the third display area 23 is easily depressed with respect to the first display area 21 and the second display area 22 after a long time 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 element 34, the elastic element 34 is elastically deformed by the pressure of the push rod 33, the elastic element 34 further drives the abutting element 31, and the abutting element 31 abuts against the first display area 21 to pull the third display area 23, so as to eliminate the depression of the third display area 23.

In another example, the mobile terminal 100 is a fold-out type terminal, and the third display area 23 is prone to arching with respect to the first display area 21 and the second display area 22 after a long time use. In the process of switching the mobile terminal 100 from the folded state to the unfolded state or after switching the mobile terminal 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 by 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 arching of the third display area 23 is eliminated.

It is understood that, in some embodiments, the pushing mechanism 30 may also include only the elastic member 34, and both 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 an urging 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 both the unfolded state and the folded state.

In this way, the elastic member 34 has a certain amount of compression when being installed, so that the elastic member 34 can push away the first display area 21 in a direction away from the third display area 23 no matter the display area is in the unfolded state or the folded state, so that the flexible display 20 is kept flat and the crease is eliminated.

In particular, in such an embodiment, the thrust means 30 comprise only the elastic element 34, so that the elastic element 34 alone assumes the task of exerting a thrust force on the first display area 21, avoiding the problem of excessive components. 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, so as to eliminate the fold.

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 display area 21 and the second display area 22 after a long time use. When the mobile terminal 100 is in the folded state or 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, and may be an element having elasticity such as silicon gel, etc. to meet different requirements.

Referring to fig. 2, in some embodiments, the flexible display 20 further includes a supporting plate 28, the supporting plate 28 is connected to the first casing 11 and the second casing 12, the supporting 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 bending toward a side where the first casing 11 is located is formed on a portion of the supporting plate 28 corresponding to the first display area 21.

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

Thus, the supporting plate 28 can serve as a bearing structure of the flexible display screen 20, and the first bending portion can bear an acting force from the pushing mechanism 30, so that the supporting plate 28 can drive the flexible display screen 20 to restore to be flat and avoid arching or sinking, and the existence of the first bending portion 291 can avoid the pushing force from directly acting 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 other material layers of the flexible display 20 and the support plate 28 may be adhered by pressure sensitive adhesive, and at the same time, the support plate 28 may be adhered to the first housing 11 and the second housing 12 by pressure sensitive adhesive. When the crease, arching or sinking of the flexible display screen 20 is eliminated, the pushing mechanism 30 can directly apply pushing force to the supporting plate 28 through the first bending portion 291, and the supporting plate 28 can drive the flexible layer of the whole flexible display screen 20 to slowly creep and expand, so that the crease of the whole flexible display screen 20 is eliminated.

It is understood that in the embodiment of the present application, the pushing force applied by the pushing mechanism 30 may be applied all the time or may be applied only for a certain time and then withdrawn after waiting for the flexible display 20 to be flattened, so as to avoid the influence on the service life of the flexible display 20 due to the long-term pushing force, and at the same time, the power may also be saved.

In addition, the first bending portion 291 is bent toward the side where the first housing 11 is located, so that the pushing 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 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, so that the force is transmitted to the first display area 21, thereby eliminating the arching or the sag.

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

As such, the first supporting portion 281 supports the first display region 21, the second supporting portion 282 supports the second display region 22, and the third supporting portion 283 supports the third display region 23, so that the entire supporting plate 28 can carry various regions protecting 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 pushing mechanism 30 only applies pushing force to the first display area 21, and it should be understood that in other embodiments, the pushing mechanism 30 may also apply pushing force to the second display area 22 at the same time, that is, the pushing mechanism 30 may also be two, one applies pushing force to the first display area 21 and the other applies pushing force to the second display area 22, and the specific implementation is not limited herein.

Further, referring to fig. 2, in some embodiments, a through hole array 2831 is formed on the third supporting portion 283.

Thus, the through hole array 2831 of the third supporting portion 283 has a movement margin, and when the mobile terminal 100 is in a folded state, the through hole array 2831 is unfolded, so that the mobile terminal 100 can be smoothly folded and unfolded, and the obstruction of the normal folding of the flexible display screen 20 is avoided.

In addition, it can be understood that, during the repeated folding of the mobile terminal 100, the first supporting portion 281 and the second supporting portion 282 may bring the first display area 21 and the second display area 22 to face or be away from each other, while the third supporting portion 283 and the third display area 23 need to be bent multiple times. The third supporting portion 283 is formed with a through hole array 2831 to ensure that the through hole array 2831 is unfolded during the folding process, so as to avoid the third supporting portion 283 from being broken due to too high rigidity.

Referring to fig. 2, in some embodiments, the supporting 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 toward a side of the second casing 12 relative to the second supporting portion 282 and 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.

As such, the driving chip 40 may be disposed on the second bending portion 292, and the stacking of the second bending portion 292 on the second supporting portion 282 may make a portion for supporting the driving chip 40 thicker, so that the impact resistance of the driving chip 40 may be effectively improved.

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 20 through a flexible Circuit board in a binding manner, and the driving Chip 40 is configured to drive the flexible display 20 to display.

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

Thus, 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 20 can be tightly fixed on the first housing 11 and the second housing 12, and the flexible display 20 is prevented from being inclined or dislocated when the mobile terminal 100 falls.

It is understood 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

11 and 12, the flexible display 20 may be folded in a length direction or in a width direction, and the third and
