Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

Due to the flexibility and rich and varied operability of the flexible electronic equipment, more and more mobile terminal enterprises release bending screen products, and the flexible electronic equipment is popular with users. However, the expectation and the demand of the user on the electronic device are also higher and higher, for example, the appearance of the flexible screen surface is an important problem affecting the subjective feeling of the user. Because the flexible screen specifically includes multilayer structure, the material on every layer is different, and the material on every layer is different, consequently when the flexible screen buckles, different layers can receive different power, especially to the optics glue film in the flexible screen, through buckling the back many times, produces a relative center sunken or convex crease easily in the department of buckling to the messenger all produces the crease corresponding to the whole flexible screen of this optics glue film. And the structure is different, the crease is not flat, but curved. Therefore, the image displayed on the screen of the electronic equipment is distorted, the display performance and the appearance expressive force of the electronic equipment are reduced, and the user experience is influenced. Therefore, how to further reduce the flexible screen fold is an important trend in the development of subsequent electronic devices while satisfying the characteristics and reliability of the flexible screen.

In view of the above, in order to solve the above problems, the present application provides an electronic device. Referring to fig. 1-2 together, fig. 1 is a schematic cross-sectional view of an electronic device according to an embodiment of the present disclosure. Fig. 2 is a schematic cross-sectional view of an electronic device according to another embodiment of the present application. The drawings in the present application only show a partial schematic diagram of a partial structure related to the present application, and do not mean that the electronic device in the present application is as shown in the drawings. The present embodiment provides an electronic apparatus 1, and specifically, the electronic apparatus 1 includes a rotating shaft assembly 10, a middle frame assembly 20, a flexible screen assembly 30, and an anti-crease assembly 40. The rotating shaft assembly 10 includes a rotating shaft 11 and a plate assembly 12 connected to the rotating shaft 11. At least part of the middle frame assembly 20 is arranged at two opposite sides of the rotating shaft assembly 10, and a gap 21 is arranged between the plate body assembly 12 and the middle frame assembly 20. The flexible screen assembly 30 is disposed at one side of the rotating shaft assembly 10 and the middle frame assembly 20. The anti-crease assembly 40 is disposed between the flexible screen assembly 30 and the rotating shaft assembly 10 and between the middle frame assembly 20, the anti-crease assembly 40 is connected to the flexible screen assembly 30, and the anti-crease assembly 40 is configured to apply a pulling force (shown as F in fig. 1 and 2) away from the rotating shaft assembly 10 to the flexible screen assembly 30, so as to reduce the height of the crease 34.

The electronic device 1 provided in this embodiment is mainly a flexible electronic device 1, and is characterized in that the electronic device 1 can be bent. The electronic device 1 may be bent several times, and the present embodiment is not limited thereto. For example, in one embodiment, the electronic device 1 may be bent once or twice, so that the electronic device 1 forms a U-shaped screen after being bent. In another embodiment, the electronic device 1 may be bent four times, so that the electronic device 1 forms a water drop screen after being bent.

The electronic device 1 provided in the present embodiment mainly includes a rotating shaft assembly 10, a middle frame assembly 20, a flexible screen assembly 30, and an anti-crease assembly 40. Among them, the rotating shaft assembly 10 is one of important parts of the electronic apparatus 1 for controlling bending of the electronic apparatus 1. The rotating shaft assembly 10 includes a rotating shaft 11 and a plate body assembly 12, and the rotating shaft 11 is formed by combining a plurality of structural members and can be bent. The bending of the rotating shaft 11 can drive the plate body assembly 12 to rotate along with the rotating shaft, so as to drive the flexible screen assembly 30 or other components arranged on the plate body assembly 12 to bend along with the rotating shaft. In addition, the hinge assembly 10 may further include a hinge 11 decoration to protect the hinge 11 so that the hinge 11 is not visible to a user from the external appearance.

The middle frame assembly 20 is a basic component of the electronic device 1, and most of the structural components of the electronic device 1 can be disposed on the middle frame, such as a circuit board, a battery, the flexible screen assembly 30, and so on. The middle frame assembly 20 may be disposed on two opposite sides of the rotating shaft assembly 10, and a gap 21 is formed between the plate assembly 12 and the middle frame assembly 20. Alternatively, the panel assembly 12 is not connected to the center frame assembly 20 and the center frame assembly 20 may be bent by itself through the flexible screen assembly 30 (as shown in fig. 1). Alternatively, the middle frame assembly 20 is bent to connect with the rotating shaft 11, and the middle frame assembly 20 can rotate through the rotating shaft 11 (as shown in fig. 2). In order to allow the electronic device 1 to be bent, the angles of rotation of the middle frame assembly 20 and the board assembly 12 are different, so that the middle frame assembly 20 cannot be connected with the board assembly 12, and the middle frame assembly 20 and the board assembly 12 need to rotate independently. The electronic device 1 will eventually assume a variety of shapes after bending, such as a U-shaped screen, a drip screen, etc. However, the flexible panel assembly 30 may have different bending angles, and particularly, the interface between the middle frame assembly 20 and the plate assembly 12, i.e., the gap 21, may have sudden bending changes, so that the fold 34 may be formed at the interface due to the material and structure of the flexible panel assembly 30.

In the electronic device 1 according to the present embodiment, the anti-crease member 40 is added to the pivot member 10, the center frame member 20, and the flexible panel member 30, so that the anti-crease member 40 is provided between the flexible panel member 30 and the pivot member 10 and the center frame member 20, and the anti-crease member 40 is connected to the flexible panel member 30. Anti crease subassembly 40 is the subassembly of resisting crease 34 as the name implies, and the setting of anti crease subassembly 40 can be used to exert the pulling force of keeping away from pivot subassembly 10 to flexible screen assembly 30, and under the effect of pulling force, the flexible screen has outwards taut, makes the trend of flexible screen reconversion. It will also be appreciated that if tension is seen as movement of the flexible screen assembly 30, as the flexible screen assembly 30 flexes, the opposite sides of the flexible screen assembly 30 will move closer to the corresponding flexible screen assembly 30 in the gap 21, thereby raising the corresponding flexible screen assembly 30 in the gap 21 to form a fold 34. The flexible screen assembly 30 on opposite sides of the fold 34 can be moved away from the fold 34 by the anti-crease assembly 40 to reduce the height of the fold 34. Under this pulling force, the convex or concave crease 34 will gradually flatten to reduce the height of the crease 34 and even eliminate the crease 34 altogether. The term "height of the fold 34 is reduced" as used herein refers to the height of the fold 34 when the flexible panel assembly 30 is flat as compared to the height of the fold 34 when the flexible panel assembly 30 is bent. The fold 34 is created, for example, when the flexible screen assembly 30 is bent, where the height of the fold 34 is 10 microns. The height of the fold 34 may be reduced by the tension created by the anti-crease assembly 40 when the flexible screen assembly 30 is flattened, which may be 5 microns in height. In addition, under the action of the pulling force, the twisted and folded fold 34 can be flattened towards the direction of the pulling force, and the display performance and the appearance expression force of the electronic equipment 1 are improved.

Alternatively, the folds 34 may be folds 34 having peaks, or folds 34 having valleys.

Alternatively, the number of the anti-crease elements 40 is two in the present embodiment, and the anti-crease elements 40 are respectively disposed corresponding to the second gaps 212.

Referring to fig. 3, fig. 3 is a schematic cross-sectional view of an electronic device according to another embodiment of the present application. In this embodiment, the plate assembly 12 includes a first plate 121 and second plates 122 disposed on opposite sides of the first plate 121, a first gap 211 is formed between the first plate 121 and the second plate 122, a second gap 212 is formed between the second plate 122 and the middle frame assembly 20, and a portion of the anti-folding assembly 40 is disposed corresponding to the second gap 212.

The plate assembly 12 provided in this embodiment may include a first plate 121 and a second plate 122, the second plate 122 is disposed on two opposite sides of the first plate 121, so that two first gaps 211 are formed between the first plate 121 and the second plate 122, and the middle frame assembly 20 is disposed on two opposite sides of the plate assembly 12, i.e., the middle frame assembly 20 is disposed on two opposite sides of the second plate 122, so that two second gaps 212 are formed between the second plate 122 and the middle frame assembly 20. In this embodiment, the two first gaps 211 and the two second gaps 212 may be bent for multiple times to form a water droplet screen, which increases the diversity of the electronic device 1.

In addition, because the drip screen needs to be bent for multiple times, and the bending angles are different, that is, the second plate 122 is bent relative to the first plate 121, and the middle frame assembly 20 is bent relative to the second plate 122. And the bending directions of the second plate bodies 122 and the middle frame assemblies 20 are also different, the two second plate bodies 122 are oppositely bent, and the two middle frame assemblies 20 are oppositely bent, so that a water drop screen is formed. The second panel 122 will form a concave, trough-shaped fold 34 with the first panel 121. Middle frame assembly 20 will form an upwardly convex, peaked crease 34 with second panel 122, thereby forming an M-shaped like crease 34.

Alternatively, the corresponding gap 21 mentioned later in this application may be understood as being arranged corresponding to the second gap 212. In other words, the anti-crease component 40 can be used to improve the condition of the crease 34 at the peak, and by pulling, not only the condition of the crease 34 at the second gap 212 can be changed, but also the condition of the crease 34 at the first gap 211 can be changed, thereby further improving the display performance of the electronic device 1.

Alternatively, the first plate 121 may be a middle plate of the rotating shaft 11, and the second plate 122 may be an inclined plate of the rotating shaft 11.

As to the specific structure of the anti-crease member 40, and how the anti-crease member 40 specifically reduces the height of the crease 34, the present application will be described in detail below.

Referring to fig. 4-7 together, fig. 4 is a schematic cross-sectional view of an electronic device according to still another embodiment of the present disclosure. Fig. 5 is a schematic diagram illustrating the principle of the flexible screen assembly when having a crease according to an embodiment of the present application. Fig. 6 is a schematic cross-sectional view of an electronic device according to yet another embodiment of the present application. Fig. 7 is a schematic view of another embodiment of the present application when the flexible screen assembly has a fold. In this embodiment, the flexible screen assembly 30 has a bending area 31 and a non-bending area 32 connected to each other, the non-bending area 32 is disposed on two opposite sides of the bending area 31, the bending area 31 corresponds to the rotating shaft assembly 10 and a part of the middle frame assembly 20, the non-bending area 32 corresponds to the rest of the middle frame assembly 20, a gap 21 is disposed between the plate assembly 12 and the middle frame assembly 20, the bending area 31 includes a crease area 33, and the crease area 33 is disposed corresponding to the gap 21;

the anti-crease assembly 40 comprises an anti-crease member 41, a first connecting member 42 and a second connecting member 43, the first connecting member 42 is connected between the middle frame assembly 20 and the anti-crease member 41, the second connecting member 43 is connected between the anti-crease member 41 and the flexible screen assembly 30, and the second connecting member 43 is arranged corresponding to the crease area 33; alternatively, the second connecting member 43 is disposed on a side of the folding zone 33 close to the non-folding zone 32.

The flexible screen assembly 30 has a bending region 31 and a non-bending region 32, where the bending region 31 is a region where the flexible screen assembly 30 bends when the electronic device 1 bends, and the non-bending region 32 is a region where the flexible screen assembly 30 does not bend when the electronic device 1 bends. The bending region 31 corresponds to the rotating shaft assembly 10 and a portion of the middle frame assembly 20, and the non-bending region 32 corresponds to the remaining middle frame assembly 20. And the portion corresponding to the gap 21 in the bending zone 31 is a creased zone 33, i.e. a crease 34 as mentioned above is created at the gap 21.

The present application describes various specific configurations of the crease resistant assembly 40. In the present embodiment, the anti-crease assembly 40 may include an anti-crease member 41, a first connecting member 42, and a second connecting member 43. Wherein the anti-crease member 41 is a member for resisting the crease 34, and the first link 42 and the second link 43 are members for fixing the anti-crease member 41. It is through the cooperation of crease-resisting piece 41, first connecting piece 42, and second connecting piece 43 that this application utilizes the difference of the hookup location of first connecting piece 42 and second connecting piece 43 to produce the pulling force.

Specifically, the first connecting member 42 is connected between the middle frame assembly 20 and the anti-crease member 41, and the second connecting member 43 is connected between the anti-crease member 41 and the flexible screen assembly 30. It will also be understood that for the anti-creasing member 41, the first and

second connectors

42, 43 are provided on opposite sides of the anti-creasing member 41. As a result of the fold 34 created by the flexible screen assembly 30 during rotation, i.e. the flexible screen assembly 30 is deformed in its direction of extension, a convex or concave fold 34 is formed. However, the middle frame assembly 20 and the anti-crease assembly 40 are not deformed, and the middle frame assembly 20 is located further outward relative to the crease area 33, so that under the action of the anti-crease member 41, the first connecting member 42 and the second connecting member 43, the middle frame can apply a pulling force to the flexible screen assembly 30 in a direction away from the rotating shaft assembly 10, so as to restore the deformed flexible screen assembly 30. In the present embodiment and hereinafter, the outer side and the inner side are understood as that the side of the center frame assembly 20 away from the rotating shaft assembly 10 is the outer side, and the side of the center frame assembly 20 close to the rotating shaft assembly 10 is the inner side.

In addition, the present application provides two arrangements for the position of the second link 43. In a first embodiment, as shown in fig. 4 and 5, the second connecting member 43 is disposed corresponding to the fold area 33. Thus, the pulling force away from the rotating shaft assembly 10 is changed to be just below or above the fold 34, and the fold 34 can be "pulled" flat under the pulling force, so that the height of the fold 34 is reduced, and the display performance and the appearance performance of the electronic device 1 are improved.

In a second embodiment, as shown in fig. 6 and 7, the second connecting member 43 can be disposed on a side of the fold line region 33 close to the non-bending region 32. It will also be appreciated that second link 43 is not disposed in correspondence with creased area 33, but rather outside creased area 33. Thus, the fold 34 can be "pulled" flat by applying a pulling force from the distal end, the height of the fold 34 is reduced, and the display performance and the appearance performance of the electronic device 1 are improved. And the second connecting piece 43 is arranged outside the crease area 33, so that the assembly difficulty of the second connecting piece 43 can be reduced, and the connection performance of the second connecting piece 43 and the flexible screen assembly 30 can be improved.

Optionally, the anti-crease 41 includes, but is not limited to, a stretch back film. Optionally, the first connecting member 42 and the second connecting member 43 include, but are not limited to, a first adhesive layer and a second adhesive layer, that is, the first connecting member 42 and the second connecting member 43 and the middle frame assembly 20 and the flexible screen assembly 30 are connected by bonding. It is also understood that the anti-crease member 41 is adhered to the center frame assembly 20 and the flexible screen assembly 30 by a glue layer.

Referring to fig. 4 and fig. 6 again, in the present embodiment, the first connecting member 42 is far from the rotating shaft assembly 10 than the second connecting member 43.

In this embodiment, the first connecting member 42 and the second connecting member 43 may be arranged in a staggered manner, and the first connecting member 42 is farther from the rotating shaft assembly 10 than the second connecting member 43, that is, the first connecting member 42 is further outside, and the second connecting member 43 is further inside. Therefore, the pulling force generated by the middle frame assembly 20 can be better transmitted to the rotating shaft assembly 10, the size of the pulling force is improved, and the display performance and the appearance expressive force of the electronic device 1 are further improved.

Please refer to fig. 8, fig. 8 is a schematic cross-sectional view of an electronic device according to another embodiment of the present application. In this embodiment, the anti-folding member 41 has a first end 411 and a second end 412 that are opposite to each other, the first end 411 is connected to the first connecting member 42, the second end 412 is connected to the second connecting member 43, and a vertical distance between the first end 411 and the middle frame assembly 20 is smaller than a vertical distance between the second end 412 and the middle frame assembly 20.

In the present embodiment, the anti-crease member 40 may be disposed in an inclined manner, and even if the vertical distance between the outer first end 411 and the middle frame member 20 is smaller, the vertical distance between the inner second end 412 and the middle frame member 20 is smaller, the tensile force generated by the middle frame member 20 may be deflected to be directed away from the rotation shaft member 10 and toward the middle frame member 20 when transmitted through the inclined anti-crease member 41. This generates a downward component force, further improving the effect of reducing the height of the fold 34, and further improving the display performance and appearance of the electronic device 1.

Alternatively, the present embodiment may make the anti-crease member 41 be obliquely disposed by changing the structure of the anti-crease member 41, or by changing the shapes of the first link 42 and the second link 43.

Referring to fig. 9-10 together, fig. 9 is a schematic cross-sectional view of an electronic device according to still another embodiment of the present application. Fig. 10 is a schematic view of a flexible screen assembly according to yet another embodiment of the present application when the flexible screen assembly has a fold. In this embodiment, the flexible screen assembly 30 has a bending area 31, the bending area 31 corresponds to the rotating shaft assembly 10 and a part of the middle frame assembly 20, a gap 21 is formed between the plate assembly 12 and the middle frame assembly 20, the bending area 31 includes a crease area 33, and the crease area 33 is disposed corresponding to the gap 21;

anti crease subassembly 40 includes anti crease 41, first connecting piece 42, and second connecting piece 43, part anti crease 41 corresponds crease district 33 sets up, first connecting piece 42 with second connecting piece 43 all connect in anti crease 41 with between the flexible screen subassembly 30, just first connecting piece 42 with second connecting piece 43 locates the relative both sides in crease district 33.

In this embodiment, the flexible screen assembly 30 also has a bending region 31 and a non-bending region 32, where the bending region 31 is a region where the flexible screen assembly 30 bends when the electronic device 1 bends, and the non-bending region 32 is a region where the flexible screen assembly 30 does not bend when the electronic device 1 bends. The bending region 31 corresponds to the rotating shaft assembly 10 and a portion of the middle frame assembly 20, and the non-bending region 32 corresponds to the remaining middle frame assembly 20. And the portion corresponding to gap 21 in bending zone 31 is crease zone 33, i.e. crease 34 as mentioned above is created at gap 21.

It can be seen from the above that the first connecting member 42 is connected to the middle frame, and the second connecting member 43 is connected to the flexible screen assembly 30 to generate the pulling force. While this embodiment describes another construction of the anti-crease assembly 40. For example, the anti-crease assembly 40 may likewise include an anti-crease member 41, a first connector 42, and a second connector 43. Wherein the anti-crease member 41 is a member for resisting the crease 34, and the first link 42 and the second link 43 are members for fixing the anti-crease member 41. It is through the cooperation of crease-resisting piece 41, first connecting piece 42, and second connecting piece 43 that this application utilizes the difference of the hookup location of first connecting piece 42 and second connecting piece 43 to produce the pulling force.

Specifically, the first connecting member 42 and the second connecting member 43 are both connected between the anti-folding member 41 and the flexible screen assembly 30, that is, the first connecting member 42 and the second connecting member 43 are both the anti-folding member 41 and the flexible screen assembly 30, and it can also be understood that the first connecting member 42 and the second connecting member 43 are disposed on the same side of the anti-folding member 41. And the first connecting piece 42 and the second connecting piece 43 are disposed on two opposite sides of the fold line area 33, that is, the first connecting piece 42 and the second connecting piece 43 are disposed on two sides of the fold line 34. As a result of the fold 34 created by the flexible screen assembly 30 during rotation, i.e. the flexible screen assembly 30 is deformed in its direction of extension, a convex or concave fold 34 is formed. However, the anti-creasing member 41 is not deformed and therefore the anti-creasing member 41 may impart a restoring force to the flexible screen assembly 30 via the first and

second coupling members

42, 43, i.e. a pulling force placed back from the middle of the crease 34 "pulls" the crease 34 flat to both sides of the crease 34. The pulling force can also be regarded as an elastic restoring force given to the flexible screen assembly 30 by the crease resisting member 41, one of the pulling forces away from the rotating shaft assembly 10 is set in a direction away from the rotating shaft assembly 10, and the other pulling force is set in a direction close to the rotating shaft assembly 10. The height of the fold 34 can be reduced by the tension, and the display performance and the appearance of the electronic device 1 can be improved. In summary, the present embodiment can apply tension to the opposite sides of the flexible screen only by the anti-creasing members 41 themselves.

Optionally, the anti-crease 41 includes, but is not limited to, a support. Alternatively, the first connecting member 42 and the second connecting member 43 include, but are not limited to, a first adhesive layer and a second adhesive layer, that is, the first connecting member 42 and the second connecting member 43 and the anti-crease member 41 are connected to the flexible screen assembly 30 by bonding. It will also be understood that the anti-crease member 41 is attached to the flexible screen assembly 30 by means of a glue layer.

Please refer to fig. 11, wherein fig. 11 is a schematic cross-sectional view of an electronic device according to another embodiment of the present application. In the present embodiment, the anti-crease member 40 may be disposed only in a partial region between the middle frame member 20, the hinge member 10 and the flexible panel member 30, and the other regions may be filled with the filler 50.
