With reference to fig. 12, 13a and 13b, in some embodiments, when the folding-screen mobile phone 100 is in the folded state, the second portion 30b of the flexible screen 30 is in the shape of a drop and is located in the accommodating cavity 11.

Fig. 14 is a schematic diagram of the folding process of the folding screen handset shown in fig. 10. As shown in fig. 14, when the folding screen mobile phone 100 is in the flattened state, the first casing 10a is disposed in the y-axis direction; when the folding screen mobile phone 100 is changed from the flat state to the folded state, the first housing 10a rotates clockwise by 90 degrees and is arranged along the z-axis direction, and in the rotating process, the first housing 10a drives the first part 30a of the flexible screen 30 to rotate clockwise together; when the flexible screen 30 is in the flat state, the second casing 10b is arranged along the y-axis direction, the second casing 10b rotates 90 degrees counterclockwise and is arranged along the z-axis direction, and in the rotating process, the second casing 10b drives the third portion 30c of the flexible screen 30 to rotate together.

Referring back to fig. 11a, a support assembly 101 is disposed between the folding assembly 20 and the flexible screen 30.

In some embodiments, with continued reference to fig. 11a, the support assembly 101 is positioned between the second portion 30b of the flexible screen 30 and the folding assembly 20. When the flexible screen 30 is in the flattened state, the supporting member 101 is configured to abut against the second portion 30b of the flexible screen 30, so that the deformation of the flexible screen 30 is flattened. The support member 101, together with the housing 10, abuts against the flexible screen 30 when the folding screen phone 100 is unfolded flat, so that the flexible screen 30 is unfolded.

The support assembly 101 is described in detail below with reference to the drawings.

Fig. 15a is a schematic view of the support assembly of the folding screen handset shown in fig. 10. As shown in fig. 15a, the support assembly 101 includes a first support plate 50, a second support plate 60, a first adhesive member 70 and a second adhesive member 80, the first support plate 50 is fixed between the first door panel 220a and the flexible screen 30, the second support plate 60 is fixed between the second door panel 220b and the flexible screen 30, the first support plate 50 has a first surface 50a opposite to the first door panel 220a, and the second support plate 60 has a second surface 60a opposite to the second door panel 220 b. The first surface 50a is adhered to the first door panel 220a by the first adhesive 70, and the second surface 60a is adhered to the second door panel 220b by the second adhesive 80.

With reference to fig. 11a, 13a and 15a, when the foldable screen mobile phone 100 is in a folded state, the first support plate 50 is flat, and the second support plate 60 is flat; when the foldable screen mobile phone 100 is in the flat state, the first support plate 50 is flat, and the second support plate 60 is flat. It should be noted that "flat" includes not only absolute flat in a geometric sense but also a flat degree within a tolerance.

In some embodiments, the first support plate is not bent and the second support plate is not bent. The term "not bent" means that the first support plate and the second support plate are not bent by bending of the flexible screen.

Thus, the first support plate 50 and the second support plate 60 are kept flat when being bent and flattened, so that the flexible screen 30 can be folded and flattened for many times, the first support plate 50 and the second support plate 60 can still keep the flat state during assembly to the maximum extent, and then are located on the same plane when the folding screen mobile phone 100 is in the flattened state.

With reference to fig. 13a and 15a, in some embodiments, when the foldable screen phone 100 is in the folded state, the first supporting plate 50 is located in a plane parallel to the first door panel 220a, and the second supporting plate 60 is located in a plane parallel to the second door panel 220 b. During the folding of the folding-screen mobile phone 100, the first support plate 50 rotates with the first door 220a, and the second support plate 60 rotates with the second door 220 b.

Referring to fig. 11a and 15a together, in some embodiments, when the foldable screen phone 100 is in the flat state, the surface of the first support plate 50 facing the flexible screen 30 and the surface of the second support plate 60 facing the flexible screen 30 are located on the same plane. It should be noted that the aforementioned "same plane" does not only mean a geometrically absolute plane, but also includes two planes within a tolerance.

In some embodiments, the first support plate and the second support plate provide a flat support surface for the flexible screen when the electronic device is in a flattened state.

With reference to fig. 14 and 15a, by providing the first support plate 50 and the second support plate 60, when the width J of the folding assembly 20 is narrow and the bending radius of the flexible screen 30 is small, the first support plate 50 and the second support plate 60 can also ensure the flatness of the bending position when the flexible screen 30 is flat.

As shown in fig. 15a, in some embodiments, the first adhesive 70 is circumferentially disposed along the first surface 50a and the second adhesive 80 is circumferentially disposed along the second surface 60a.

In some embodiments, the first adhesive member 70 and the second adhesive member 80 may have a square ring shape as shown in fig. 15a, and the first adhesive member 70 and the second adhesive member 80 may also have a circular ring shape.

In other embodiments, the first adhesive member 70 may not be circumferentially disposed along the first surface 50a, for example, the first adhesive member 70 may have a zigzag shape as shown in fig. 15b, or may have two strips as shown in fig. 15 c. It is understood that the zigzag and stripe shapes are merely examples of the shape of the first adhesive 70 and do not constitute a limitation on the shape of the first adhesive 70.

The shape and the relative position relationship between the second adhesive member 80 and the second surface 60a can be found in the above-mentioned embodiment of the first adhesive member 70, and are not described herein again.

It should be noted that the first adhesive member 70 may be disposed at any position on the first surface 50a, so that the first surface 50a can be sufficiently adhered to the first support plate 50. Similarly, the second adhesive member 80 may be disposed at any position on the second surface 60a so that the second surface 60a can be sufficiently adhered to the second support plate 60. Thereby ensuring that the first support plate 50 and the second support plate 60 are on the same plane when the folding screen mobile phone 100 is unfolded.

The structure and processing of the first adhesive member 70 and the second adhesive member 80 are described in the following embodiments.

In some embodiments, when the first door panel 220a and the second door panel 220b are provided with the holes 222, the first adhesive member 70 may be disposed on the holes 222 to isolate the first support plate 50 from the rotating shaft 210. The second adhesive member 80 may be disposed on the hole 222 to isolate the second support plate 60 from the rotation shaft 210.

Illustratively, as shown in fig. 11a, when the foldable screen mobile phone 100 is in a flattened state, the surfaces of the first support plate 50, the second support plate 60, the first housing 10a and the second housing 10b opposite to the flexible screen 30 are all located on the same plane, so that the flexible screen 30 is flattened by the first support plate 50, the second support plate 60, the first housing 10a and the second housing 10 b.

Fig. 16a is an assembly schematic view of a folding screen mobile phone according to an embodiment of the present application. As shown in fig. 16a, by providing the first adhesive member 70, the inclination angle θ between the first door panel 220a and the preset position can be absorbed. Similarly, if the inclination angle between the second door 220b and the predetermined position is set, the second adhesive member 80 may absorb the inclination angle between the second door 220b and the predetermined position. The first adhesive member 70 and the second adhesive member 80 cooperate to absorb the height difference L between the first door panel 220a and the second door panel 220b so that the first support plate 50 and the second support plate 60 can be positioned on the same plane, and thus the flexible screen 30 disposed on the first support plate 50 and the second support plate 60 can be flattened by the first support plate 50 and the second support plate 60. Wherein the inclination angle is generated due to an error in a machining process and an assembling process. The predetermined position is the same plane that the first door panel 220a and the second door panel 220b should be located in theoretically.

Fig. 16b is a schematic diagram of orthographic projections of the first support plate, the second support plate, the first door panel and the second door panel of the folding screen mobile phone shown in fig. 16a on the flexible screen 30. As shown in fig. 16b, in some embodiments, the orthographic projection of the first door panel 220a on the flexible screen 30 is within the boundaries of the orthographic projection of the first support plate 50 on the flexible screen 30; and/or the orthographic projection of the second door panel 220b on the flexible screen 30 is located within the boundaries of the orthographic projection of the second support panel 60 on the flexible screen 30. The first door panel 220a is smaller than the first support plate 50, and the second door panel 220b is smaller than the second support plate 60. Thus, the distance between the first door panel 220a and the second door panel 220b can be increased appropriately, and a larger escape space is provided for the device of the rotating shaft 210.

In other embodiments, the orthographic projection of the first support plate 50 on the flexible screen 30 is within the boundaries of the orthographic projection of the first door panel 220a on the flexible screen 30; and/or the orthographic projection of the second support panel 60 on the flexible screen 30 is within the boundaries of the orthographic projection of the second door panel 220b on the flexible screen 30. The first door 220a is larger than the first support plate 50 and the second door 220b is larger than the second support plate 60 on the premise of ensuring that the first support plate 50 and the second support plate 60 can provide a flat support surface for the flexible screen 30. In this way, the distance between the first and second support plates 50, 60 may be increased appropriately to provide design space for various structural designs of the first and/or second door panels 220a, 220 b.

In some embodiments, the first adhesive member 70 and the second adhesive member 80 may be formed by dispensing. The dispensing can effectively absorb the height difference between the first door panel 220a and the second door panel 220b and the flatness of the first door panel 220a and the second door panel 220 b.

Illustratively, first, glue (e.g., white glue, photo-sensitive (UV) glue, etc.) is dropped onto the first door panel 220a and the second door panel 220b, respectively. Next, the first support plate 50 is disposed on the uncured adhesive on the first door panel 220a and the second support plate 60 is disposed on the uncured adhesive on the second door panel 220b by clamping the jig. Again, the first and second support plates 50 and 60 are pressed and pressurized. When the glue is cured, the glue between the first support plate 50 and the first door panel 220a forms a first adhesive 70, and the glue between the second support plate 60 and the second door panel 220b forms a second adhesive 80.

In some embodiments, the first support plate 50 and the second support plate 60 are both rigid support plates. Compared with a flexible plate, the rigid support plate is stable in shape and not easy to deform, and the flatness requirement can still be guaranteed after the flexible screen 30 is folded and flattened for multiple times.

In some embodiments, the rigid support plate is a steel plate.

In some implementations, the first support plate 50 and the second support plate 60 are both made of non-bendable steel plates. For example, stainless steel SUS316.

In some embodiments, the thickness of the first and second support plates 50 and 60 may be 0.15mm.

Fig. 17a is a schematic structural diagram of a first adhesive member 70 in a folding-screen mobile phone according to an embodiment of the present disclosure. As shown in fig. 17a, the edge of the first adhesive member 70 may have an irregular shape. The first adhesive member 70 may have a non-uniform thickness in the z-direction, for example, the thickness K1 is greater than the thickness K2.

In some embodiments, the first adhesive member 70 may have a continuous square circular configuration as shown in fig. 17 a.

Fig. 17b is a schematic structural diagram of another embodiment of a first adhesive member in a folding-screen mobile phone according to an embodiment of the present application. As shown in fig. 17b, the first adhesive member 70 may be arranged in a dot shape. For example, a uniform dot arrangement as shown in fig. 17b may be used.

As shown in fig. 17b, the first adhesive member 70 arranged in a dot shape includes a first point 70a, a second point 70b, and a third point 70c.

In some embodiments, each of the dots of the first adhesive member 70 may have different shapes, for example, the first dot 70a may have a square shape, the second dot 70b may have a circular shape, and the third dot 70c may have an irregular shape with irregular curved edges as shown in fig. 17 b. The shape of each dot in the first adhesive member 70 arranged in a dot shape is not limited in the present application.

In other embodiments, all the points of the first adhesive member 70 arranged in a point shape may have the same shape, for example, they may be all square, all round, or all irregular patterns with irregular curved edges.

Fig. 17c is a schematic structural diagram of a first adhesive member in a folding-screen mobile phone according to another embodiment of the present application. As shown in fig. 17c, the first adhesive member 70 may be partially continuously disposed and partially dotted. It is understood that the structure of the second adhesive member 80 can refer to the structure of the first adhesive member 70, and the structure of the second adhesive member 80 will not be described in detail in this embodiment of the application.

Fig. 18a is a schematic structural diagram of a folding screen mobile phone according to an embodiment of the present application. Fig. 18b is a schematic cross-sectional view of the folding screen phone 100 of fig. 18a in a C-C view.

In some embodiments, the fifth adhesive member 140 is circumferentially disposed along the fifth surface 130 a.

It should be noted that the structure and shape of the fifth adhesive member 140 can refer to the structure and shape of the first adhesive member 70 in the foregoing embodiments, which are not described herein again.

Fig. 19a is a schematic view of the folded mobile phone shown in fig. 18a in a folded state. Fig. 19b is a schematic cross-sectional view of the folding screen phone 100 shown in fig. 19a taken along the line D-D. Referring to fig. 19a and 19b together, in some embodiments, when the foldable mobile phone 100 is in the folded state, the side of the first support plate 50 close to the axis a-a 'of the rotating shaft and the side of the second support plate 60 close to the axis a-a' of the rotating shaft both extend into the accommodating space 241.

In other embodiments, the side of the first support plate 50 near the axis a-a 'of the rotating shaft and the side of the second support plate 60 near the axis a-a' of the rotating shaft may be located outside the back cover 240.

The connections between the first support plate 50 and the first door panel 220a, between the second support plate 60 and the second door panel 220b, and between the third support plate 130 and the third door panel 220c are described in the above embodiments, and the connections between the first support plate 50 and the flexible screen 30, and between the second support plate 60 and the flexible screen 30 are described below with reference to the drawings.

Fig. 20a is a schematic disassembly view of a folding screen mobile phone provided with a double door panel according to an embodiment of the present application. As shown in fig. 20a, in some embodiments, first support plate 50 has a third surface 50b facing flexible screen 30, and second support plate 60 has a fourth surface 60b facing flexible screen 30; the flexible screen 30 is connected to a side of the third surface 50b away from the axis a-a 'of the rotation shaft and to a side of the fourth surface 60b away from the axis a-a' of the rotation shaft.

It should be noted that, in the xy-plane, the third surface 50b has a first end 50b1 and a second end 50b2 along the y-direction, wherein the distance between the first end 50b1 and the axis a-a 'of the rotating shaft along the y-direction is greater than the distance between the second end 50b2 and the axis a-a' of the rotating shaft along the y-direction. The side of the third surface 50b remote from the axis a-a' of the shaft is referred to as the first end 50b1.

As shown in fig. 20a, in some embodiments, the support assembly 101 includes a third adhesive 110 and a fourth adhesive 120; the third adhesive member 110 may be disposed on a side of the third surface 50b away from the axis a-a 'of the rotating shaft, and may be disposed in a dotted manner along a direction parallel to the axis a-a' of the rotating shaft; the fourth adhesive member 120 may be disposed on a side of the fourth surface 60b away from the axis a-a 'of the rotating shaft, and may be disposed in a dotted manner along a direction parallel to the axis a-a' of the rotating shaft; the third surface 50b is adhered to the flexible screen 30 by a third adhesive member 110, and the fourth surface 60b is adhered to the flexible screen 30 by a fourth adhesive member 120.

The punctiform layout mode is favorable for relieving the deformation of the flexible screen 30 during folding, so that the connection relationship between the flexible screen 30 and the first supporting plate 50 is changed, the stress and the deformation at different positions are balanced, the deformation of the first supporting plate 50 is avoided, and the flatness requirement can still be ensured after the flexible screen 30 is folded and flattened for multiple times. Meanwhile, the drop-shaped structure of the flexible screen 30 when folded does not receive the influence of the support plate, thereby protecting the flexible screen 30.

As shown in fig. 20a, in some embodiments, at least one groove 150 is disposed on each of the third surface 50b and the fourth surface 60b; the third adhesive 110 is disposed in the groove 150 of the third surface 50b and the fourth adhesive 120 is disposed in the groove 150 of the fourth surface 60 b. In this way, a gap between the first support plate 50 and the flexible screen 30 due to the third adhesive member 110 is avoided, and when the flexible screen 30 is flattened, the first support plate 50 abuts against the flexible screen 30 to achieve flattening of the flexible screen 30.

In some embodiments, the depth of the groove 150 may be 0.15mm.

In other embodiments, as shown in fig. 20b, in first support plate 50, groove 150 extends from a surface of first support plate 50 adjacent to flexible screen 30 through to a surface of first support plate 50 facing away from flexible screen 30; and/or, in the second support plate 60, the groove 150 penetrates from the surface of the second support plate 60 close to the flexible screen 30 to the surface of the second support plate 60 facing away from the flexible screen. So that the third adhesive member 110 is inserted into the groove 150 to adhere the first door panel 220a to the flexible screen 30, and the fourth adhesive member 120 is inserted into the groove 150 to adhere the second door panel 220b to the flexible screen 30.
