The size of display devices has grown larger and larger over time, but larger display devices are more inconvenient to carry during carrying. With the development of the flexible screen technology, the bendable flexible display device comes along, and meanwhile, the display device capable of being wound on the wrist comes along, so that the display device can be used like a normal display device in a flattening mode, can also be tightly wound on the wrist, cannot easily fall off and is convenient to carry. The design can not only solve the carrying problem of large-size display equipment, but also meet the use requirements of different scenes.
However, such a flexible display device is prone to problems when being bent, specifically, the flexible display device generally includes a flexible screen and a flexible supporting mechanism, both of which can be bent, and since the flexible supporting mechanism has a certain thickness, a neutral layer of the flexible supporting mechanism and a neutral layer of the flexible screen are not in the same plane, which results in different bending degrees of the flexible supporting mechanism and the flexible screen, but since the flexible supporting mechanism and the flexible screen are generally fixed together, the flexible screen is prone to breakage or crack during bending.
It should be noted that the neutral layer of the flexible supporting mechanism refers to a plane in which the length of the flexible supporting mechanism is not changed during the bending process, and the neutral layer of the flexible screen refers to a plane in which the length of the flexible screen is not changed during the bending process, and since the thickness of the flexible screen is much smaller than that of the flexible supporting mechanism, the upper/lower surfaces of the flexible screen can be regarded as the plane in which the neutral layer of the flexible screen is located.
In order to solve the above problem, referring to fig. 1 to 4, an embodiment of the present invention provides a supporting device for a flexible display apparatus, the supporting device having a first state and a second state, wherein the supporting device is straight in the first state, and the supporting device is bent and deformed in the second state.

The screen body supporting surface 11 is used for supporting the flexible screen 4, and the flatness of the flexible screen 4 is guaranteed in normal use. Illustratively, the screen body supporting surface 11 may be a surface of the flexible supporting plate 1 facing the user when the user uses the display device including the supporting means. The first end 12 and the second end 13 are two ends of the flexible supporting plate 1 in the extending direction X, respectively, and since the flexible supporting plate 1 is flexible and bendable, at least one of the first end 12 and the second end 13 can move relatively to the other.
The bending component 2 is arranged on one side of the flexible supporting plate 1 opposite to the screen body supporting surface 11, and the bending component 2 comprises a bending structure 21 capable of bending and deforming. In the display device including the supporting device, the bending component 2 is located on one side of the flexible supporting plate 1 departing from the flexible screen 4, and the flexible supporting plate 1 is used for arranging the flexible screen 4 on the bending component 2.

The sliding connector 3 is used for connecting the flexible supporting plate 1 and the bending structure 21, and includes a sliding rail 32 and a sliding member 31 that can move relative to the sliding rail 32. The sliding rail 32 may be a rail structure protruding outward, or a sliding groove structure formed by recessing inward, which is not limited in this embodiment of the application, as long as the extending direction of the sliding rail 32 is parallel to the extending direction X of the flexible supporting plate 1, and the sliding member 31 can move relative to the extending direction of the sliding rail 32.
The extending direction X of the flexible supporting plate 1 needs to be determined according to the state of the flexible supporting plate 1. As shown in fig. 1, when the flexible supporting plate 1 is in the first state, the extending direction X of the flexible supporting plate 1 is a linear direction and is parallel to the length direction of the flexible supporting plate 1; as shown in fig. 3, when the flexible supporting plate 1 is in the second state, the extending direction of the flexible supporting plate 1 is a curved direction and is parallel to the overall extending path of the flexible supporting plate 1. In addition, since the flexible supporting plate 1, the flexible screen 4 and the bending member 2 are connected to each other and bent or flattened at the same time, the extending directions X of the three are substantially the same. The extending direction X mentioned later in this embodiment of the present application may be the extending direction X of any one of the flexible supporting plate 1, the flexible screen 4, and the bending assembly 2, and this embodiment of the present application is not described again.

For example, the sliding connectors 3 may be respectively disposed on two surfaces of the bending structure 21 opposite to the flexible support plate 1 in the thickness direction, or may be disposed on two sides of the bending structure 21 and the flexible support plate 1 along the second direction Y, where the second direction Y is the width direction of the bending structure 21 and the flexible support plate 1.
According to the embodiment of the application, the flexible support plate 1 and the bending structure 21 can be movably arranged through the sliding connection piece 3, so that when the display equipment is bent, the flexible screen 4 on the support device can move along the self extending direction X relative to the bending structure 21. This application embodiment need not complicated mechanical structure, can alleviate because of flexible screen 4 is different with the degree of buckling of structure 21 of buckling, leads to the problem that flexible screen 4 was excessively dragged, improves the reliability of buckling.
As shown in fig. 3 and 4, in some embodiments, the bending assembly 2 further includes a main body structure 22, the main body structure 22 is disposed at one side of the bending structure 21 along the extending direction X, the first end 12 is fixed to the main body structure 22, and the second end 13 is connected to the bending structure 21, so that when the bending structure 21 is bent and deformed, the second end 13 moves along the extending direction X relative to the bending structure 21.
The main body structure 22 and the bending structure 21 are connected, and in the process of converting the first state to the second state, the shape of the main body structure 22 is always kept unchanged, and the bending structure 21 is bent relative to the main body structure 22 and is wound on the wrist of a user. The size of the bending structure 21 of the main structure 22 is determined according to actual use conditions, and the embodiment of the present application is not limited.
The first end 12 of the flexible support plate 1 is fixed to the main structure 22 and the second end 13 can be connected to the bending structure 21 by means of the sliding connection 3. During the transition from the first state to the second state, the first end 12 is held stationary by the body structure 22 and the second end 13 is moved relative to the first end 12 due to the bending of the flexible support plate 1. At the same time, since the flexible support plate 1 is not in the same plane as the neutral layer of the bending structure 21, the second end 13 will also move in the extending direction X relative to the bending structure 21 in the process.
In some embodiments, the flexible supporting board 1 includes a first portion 14 and a second portion 15, the first portion 14 is located at one side of the main body structure 22, the second portion 15 is located at one side of the bending structure 21, one of the sliding member 31 and the sliding rail 32 is disposed at the bending structure 21, and the other is disposed at the second portion 15.
The first portion 14 of the flexible supporting plate 1 is arranged corresponding to the main structure 22, the second portion 15 is arranged corresponding to the bending structure 21, the first end 12 is arranged in the first portion 14, and the second end 13 is arranged in the second portion 15. Wherein, the first part 14 will not bend during wearing, and the second part 15 will bend and deform along with the bending of the bending structure 21 during wearing. Since the relative position of the first part 14 and the main structure 22 is always kept constant, the first part 14 and the fixed structure can be fixed by welding or bonding without using the sliding connector 3.
The flexible support plate 1 in the embodiment of the present application includes a first portion 14 and a second portion 15, the flexible support plate 1 is fixedly connected to the main structure 22 through the first portion 14, the second portion 15 and the bending structure 21 are not completely attached and fixed, and the two are slidably connected through the sliding connection member 3. The arrangement of the first portion 14 and the main structure 22 can improve the connection reliability between the flexible support plate 1 and the bending assembly 2, and reduce the risk of the flexible support plate 1 being separated from the bending assembly 2.
Referring to fig. 3 and fig. 5, in some embodiments, the sliding member 31 is formed to extend along a second direction Y, and the flexible supporting plate 1 is movably disposed relative to the bending structure 21 in the second direction Y, where the second direction Y intersects with the extending direction X. The second direction Y is the width direction of the flexible supporting plate 1, and optionally, the second direction Y is perpendicular to the extending direction X when the supporting device is flat.
As can be seen from the foregoing, the sliding member 31 may be disposed on the flexible supporting plate 1, and may also be disposed on the bending structure 21. As shown in fig. 5, in the embodiment of the present application, the sliding members 31 are disposed on two sides of the flexible support plate 1 along the second direction Y, and protrude and extend along a direction away from the flexible support plate 1.

The sliding member 31 enters the slide rail 32 through the rolling portion 312, and the rolling portion 312 can rotate relative to the inner wall of the slide rail 32 in the slide rail 32, so that during the movement of the sliding member 31 relative to the slide rail 32, the friction resistance between the sliding member 31 and the slide rail 32 can be reduced, and the sliding member 31 can move smoothly in the slide rail 32.
Referring to fig. 3 and 6, in some embodiments, the supporting device further includes a buffer 5 extending along the second direction Y, and the sliding element 31 is disposed on one of the bending structure 21 and the flexible supporting plate through the buffer 5.
When the bending structure 21 and the flexible support plate 1 move relatively in the second direction Y, the buffer member 5 is disposed at one end of the sliding member 31, so that the buffer member 5 can play a certain buffering role, and the position relationship between the flexible support plate 1 and the bending structure 21 in the second direction Y can be adjusted. Specifically, in the process that the supporting device is changed from the first state to the second state, the bending structure 21 drives the flexible supporting plate 1 to bend, in the process, the flexible supporting plate 1 is easy to deviate relative to the bending structure 21 in the second direction Y, at this time, the sliding part 31 can relatively move along the second direction Y and extrude the buffering part 5, the buffering part 5 can avoid one of the flexible supporting plate 1 and the bending structure 21 from directly contacting with the sliding part 31, and meanwhile, the phenomenon of excessive extrusion is avoided.

In some embodiments, the slide rail 32 is disposed on the bending structure 21, and the sliding member 31 is disposed on the flexible supporting plate 1.
As shown in fig. 3, the sliding member 31 may be located at an edge of the flexible support plate 1 along the second direction Y and extend outward, and the sliding rail 32 may be disposed at an edge of the bending structure 21 and face the flexible support plate 1. The design is favorable for timely maintaining the sliding piece 31 and the sliding rail 32 when the sliding piece 31 or the sliding rail 32 has problems, and the service life of the product is prolonged.

Alternatively, the buffer 5 may be disposed in the mounting groove 16, and one end of the buffer 5 abuts against the flexible support plate 1 and the other end abuts against the sliding member 31. The buffer member 5 can prevent the sliding member 31 from directly contacting the flexible support plate 1, and can reduce the amount of pressing force generated on the flexible support plate 1 by the movement of the sliding member 31 in the second direction Y.
Referring to fig. 3 and 7, in some embodiments, the bending structure 21 includes a main body 211, and protruding portions 212 located on two sides of the main body 211 in the second direction Y and protruding toward the flexible support plate 1, wherein the flexible support plate 1 is located between the two protruding portions 212.
