For the sake of convenience of the following description, the respective directions of the cellular phone 1 will now be defined. As shown in fig. 3, the length direction of the display 20 is the same as the length direction of the mobile phone 1, and is the x-axis direction; the width direction of the display screen 20 is the same as that of the mobile phone 1, and is the y-axis direction; the thickness direction of the display 20 is the same as the thickness direction of the mobile phone 1, and is a z-axis direction, and the z-axis direction is perpendicular to the light emitting surface 21 of the display 20. The light emitting surface 21 of the display 20 is a surface of the display 20 for emitting light. As can be seen from fig. 2 to 6, the support assembly 10 supports the display screen 20 along the z-axis direction.

The specific structure of the support assembly 10 will be described in detail below with reference to the accompanying drawings.

As can be seen from fig. 3 and 6, the support assembly 10 includes a first support member 11, a second support member 12, and a hinge structure 13. The rotating shaft structure 13 is located between the first support part 11 and the second support part 12, and is rotatably connected to the first support part 11 and the second support part 12, respectively. The first support member 11 and the second support member 12 can be folded about the axis of the shaft of the pivot structure 13.

In some embodiments of the present application, the first support member 11 includes a first middle frame (not shown) and a first back cover (not shown), the second support member 12 includes a second middle frame (not shown) and a second back cover (not shown), and the first support member 11 and the second support member 12 have the same or a mirror image structure, which is not particularly limited in this application.

In some implementations, the first middle frame includes a first bezel (not shown) and a first middle plate (not shown). The first middle plate is positioned in an area formed by the first frame in a surrounding mode and is connected with the inner surface of the first frame. The first rear cover is fixed on the first frame, and the first rear cover and the first middle plate are arranged oppositely. The first rear cover, the first middle plate and the first frame jointly enclose a first accommodating space. Similarly, the second middle frame includes a second frame (not shown) and a second middle plate (not shown). The second middle plate is positioned in an area formed by the second frame in a surrounding mode and is connected with the inner surface of the second frame. The second rear cover is fixed on the second frame, and the second rear cover and the second middle plate are arranged oppositely. And a second containing space is enclosed by the second rear cover, the second middle plate and the second frame. The components such as the battery and the motherboard in the mobile phone 1 are accommodated in the first accommodating space and/or the second accommodating space.

In some implementations, the first back cover can be fixed to the first bezel by various fastening methods such as a snap, an adhesive, and the like. The second rear cover can be fixed on the second frame through various fixing modes such as buckles, glue and the like. It is to be understood that, in some alternative implementations, the first back cover is integrally formed with the first side frame, and the second back cover is integrally formed with the second side frame, which is not specifically limited in this application.

Having described the specific structure of the support assembly 10, the following description will proceed with reference being made to the drawings in detail to describe the specific structure of the display screen 20.

In some implementations, the display screen 20 includes a flexible screen. The flexible screen is a screen which has bendability and can display pictures. In some implementations, the flexible screen can be an Organic Light Emitting Diode (OLED) display screen. It is understood that the flexible screen may also be other flexible screens capable of displaying pictures, and this application is not limited in this respect.

As can be seen from fig. 3 and 6, the display panel 20 includes a first fixing area 21, a second fixing area 22 and a bending area 23. The bending region 23 is located between the first fixing region 21 and the second fixing region 22, and is connected to the first fixing region 21 and the second fixing region 22, respectively. The first fixing area 21 is opposite to the first supporting part 11 and fixed with the first supporting part 11, the second fixing area 22 is opposite to the second supporting part 12 and fixed with the second supporting part 12, and the bending area 23 is opposite to the rotating shaft structure 13.

In some implementations, the first fixing area 21 is fixed to the first support member 11 by adhesive bonding. The second fixing region 22 is fixed to the second support member 12 by adhesive bonding. In alternative other implementations, the first fixing region 21 and the first supporting component 11, and the second fixing region 22 and the second supporting component 12 may also be fixed by other manners such as screwing, snapping, and welding, which is not specifically limited in this application.

As can be seen from fig. 3 and 6, in some implementations, the first fixing area 21 of the display screen 20 is fixed to a side of the first middle plate facing away from the first rear cover, and the second fixing area 22 of the display screen 20 is fixed to a side of the second middle plate facing away from the second rear cover. In some implementations, there is a certain distance between the edge of the first fixing area 21 of the display screen 20 and the first frame, and there is a certain distance between the edge of the second fixing area 22 of the display screen 20 and the second frame, so that when the mobile phone 1 is collided, the acting force generated during collision is transmitted to the display screen 20 through the first frame or the second frame to damage the display screen 20.

After the specific structures of the support assembly 10 and the display 20 are introduced, the structural changes of the support assembly 10 and the display 20 during the folding and unfolding of the mobile phone 1 will be briefly described.

As can be seen from fig. 3 and fig. 6, in the process of folding the mobile phone 1, the bending region 23 in the display 20 is gradually bent into an arc state, and one end of the first fixing region 21 away from the bending region 23 and one end of the second fixing region 22 away from the bending region 23 are close to each other. In the process of unfolding the mobile phone 1, the bending region 23 in the display 20 is gradually unfolded to be in a flat state, and one end of the first fixing region 21 far away from the bending region 23 is far away from one end of the second fixing region 22 far away from the bending region 23. That is, when the first and second support members 11 and 12 are folded about the hinge structure 13, the bending region 23 of the display screen 20 is gradually bent, and the first and second fixing regions 21 and 22 of the display screen 20 are folded with respect to the hinge structure 13.

In some implementations, the handset 1 is an in-folded device, i.e., the display 20 is located inside the support assembly 10 when the handset 1 is in a folded state. In some other alternative embodiments, the mobile phone 1 is an external folding device, i.e. the display 20 is located outside the support member 10 when the mobile phone 1 is in the folded state.

After describing the specific structures of the support assembly 10 and the display screen 20, the specific structure of the first shield assembly 30 will be described in detail below with reference to the accompanying drawings.

As shown in fig. 3, the number of the first shield members 30 is two. The two first protection assemblies 30 are respectively located at two opposite ends of the rotating shaft structure 13, and located at two opposite ends of the bending region 23 in the y-axis direction in the display screen 20. Wherein, two first protection component 30 are used for protecting the edge of the bending zone 23 of display screen 20 to avoid the edge of the bending zone 23 to expose outside, thereby improve the outward appearance effect of cell-phone 1, and can avoid the edge of external collision bending zone 23, improve the stability of cell-phone 1, can also avoid impurity to permeate to inside cell-phone 1 through the edge of the bending zone 23 of display screen 20, improve the reliability of cell-phone 1. It is understood that since the first fixing region 21, the bending region 23 and the second fixing region 22 are sequentially arranged along the x-axis in the display screen 20, the edge of the bending region 23 refers to a pair of edges of the bending region 23 perpendicular to the y-axis.

As can be seen in conjunction with fig. 7 and 8, the first shield assembly 30 includes a shield member 100, a first fixing part 200, and a second fixing part 300. The shielding member 100 is fixed relative to the first fixing part 200, the first fixing part 200 is fixed relative to the second fixing part 300, and the second fixing part 300 is fixed relative to the rotation shaft in the rotation shaft structure 13. As can be seen from fig. 6, 7 and 8, the shielding member 100 is located on a side of the display screen 20 opposite to the support assembly 10 and covers an edge of the bending region 23 in the display screen 20.

As shown in fig. 7 and 8, the shielding member 100 includes a soft material 110 and a connecting member 120 having different materials. The soft material 110 is an elastic material, and the connecting member 120 is an ultra-thin member. In some implementations, the color scheme of the first protective component 30 can also be expanded because different materials can correspond to different color schemes.

As shown in fig. 6, 8 and 9, the soft material 110 is correspondingly disposed at the edge of the bending region 23. Soft component 110 includes oppositely disposed first and second surfaces. The first surface of the soft member 110 is a surface of the soft member 110 facing away from the display 20, and the second surface of the soft member 110 is a surface of the soft member 110 facing toward the display 20.

In some implementations, the first surface of the soft component 110 is an arcuate surface that projects outward away from the second surface of the soft component 110 along the x-axis direction middle region.

As shown in fig. 6, 8 and 9, the connecting member 120 includes a first extension 121 and a second extension 122 at opposite ends of the soft member 110.
