In a practical application, the supporting plate 1 may be an integrated supporting plate or a profile supporting plate, or may be a supporting plate structure including a battery or a circuit board, and the like, and the application is not limited specifically; the supporting plate 1 may specifically include, but is not limited to, a first plate 101, a second plate 102, and a third plate 103, which are connected in sequence, and in other embodiments, two supporting plates 1, four supporting plates 1, N supporting plates 1, and the like may also be included. The folding component 2 may be a longitudinally laminated sheet-shaped structure, a horizontally parallel interpenetration structure, an interpenetration structure of a linear frame, or an interpenetration hinge structure, as long as the interpenetration structure is adopted, and a person skilled in the art can set the structure according to actual needs, and the application is not limited specifically; the folding component 2 may specifically include, but is not limited to, a first flexible connection layer 203, a first penetrating support layer 201, a first penetrating subunit, a second flexible connection layer 204, a second penetrating support layer 202, and a second penetrating subunit, and in other embodiments, the folding component 2 may also be one folding component 2, three folding components 2, N-1 folding components 2, and the like; the first penetrating support layer 201 mainly comprises a plurality of first penetrating subunits which are penetrated mutually side by side, and the second penetrating support layer 202 mainly comprises a plurality of second penetrating subunits which are penetrated mutually side by side; the first penetrating support layer 201 penetrates through the first flexible connection layer 203 and is fixedly connected between the first plate 101 and the second plate 102, and the second penetrating support layer 202 penetrates through the second flexible connection layer 204 and is fixedly connected between the second plate 102 and the third plate 103. The following steps can be also included: fixedly connected with the first plate 101, the first penetrating support layer 201, the second plate 102, the second penetrating support layer 202 and the third plate 103 in sequence, wherein the first flexible connection layer 203 and the second flexible connection layer 204 are constructed into an integral flexible connection layer 21, cover the integral side surface of the integral flexible connection layer in sequence, are connected with the support plate 1 in a gluing manner, and are penetrated and arranged with the penetrating support layer 22.

When the folding device 10 is in the unfolded state, the flexible display screen 20 is laid on the same plane of the side surface of each supporting plate 1 fixedly connected with each folding part 2, or is glued or laminated. Meanwhile, the normal golden ratio size of a general display screen is 16:9, in the three-panel structure of the embodiment, the ratio of the size of the display area increased by each panel is close to 16:9, one important point of the present application is that the three-panel structure is designed to be close to a similar three-vertical-panel structure, the ratio of the size of the whole flexible display screen 20 is 3 × 9:16 ≈ 16:9, that is, the whole flexible display screen 20 is still the golden ratio size of 16:9, that is, the golden ratio size of media playing of a conventional large horizontal screen, and a user obtains better experience in a single vertical screen and the whole large horizontal screen, so that the use value of the present application is greatly improved.

When the folding device 10 is in a folded state, the volume of a supporting space contained by the flexible display screen 20 folded outwards needs to be reduced, and a plurality of first penetrating sub-units which penetrate through each other side by side move close to each other to form a supporting inner contour; the supporting space supported by the flexible display screen 20 folded inwards needs to be enlarged, and then the second interpenetration subunits which are mutually penetrated side by side move away from each other to form a supporting outer contour. From top to bottom, the first plate 101, the second plate 102, and the third plate 103 are stacked in sequence, so that a part of the display surface of the flexible display 20 supported by the second plate 102 faces a part of the display surface of the flexible display 20 supported by the third plate 103, and a part of the display surface of the flexible display 20 supported by the first plate 101 faces upward. In the example of the combination of the inward folding and the outward folding of the three support plates 1 of the embodiment, since the portion of the flexible display screen 20 supported by the second plate 102 and the portion of the flexible display screen 20 supported by the third plate 103 face each other and are hidden and protected by the support structure, and the portion of the flexible display screen 20 supported by the first plate 101 can still be normally used, the defect that the back display area of some outward folding structure equipment is always exposed and vulnerable is overcome, and the problem that some inward folding structure equipment cannot work immediately and needs to be opened to work is solved.

In summary, since the flexible connecting layer 21 on the folding member 2 has no change in size during the outward folding and inward folding processes, the flexible display 20 attached thereon has no change in size; the penetrating support layer 22 penetrating under the flexible connection layer 21 adapts to the volume change of the support structure in the outward folding state and the inward folding state, so that the problems of excessive extrusion and jacking of the flexible display screen 20 caused by difficult adaptation of the folded volume are solved, and the technical effects of protecting the flexible display screen 20 and preventing the flexible display screen from being damaged are further achieved.

It is understood that the first plate 101 at the beginning first end and the third plate 103 at the end second end of the folding device 10 can be extended in one direction only for one set of opposite sides, the second plate 102 can be extended in two directions, the second plate 102 and the third plate 103 are connected as an inward folding area, so that the bend 12 is directed to the side perpendicular to the display surface of the flexible display screen 20 and a part of the bend 12 is higher than the display surface of the flexible display screen 20, so as to facilitate the overlapping of the second folded plate 102 and the third plate 103 after inward folding; the second plate 102 is connected to the first plate 101 as an out-folding area, so that the bend 12 is directed away from the back side of the flexible display 20 and a portion of the bend 12 is lower than the back side of the support plate 1, thereby facilitating the folding and stacking of the second plate 102 and the first plate 101 after the out-folding. When the folding device 10 is in the unfolding state, the respective elbow limiting edges 121 of the double elbows 12 at the inner folding position or the outer folding position are abutted through the same rotating shaft, so that the supporting plate 1 can not rotate any further after being unfolded to the same plane, and the purpose of stopping and limiting is achieved.

When the folding device 10 is in the unfolded state, the T-shaped auxiliary support plates 15 at each folding position abut against each other and are supported on a plane by the sliding cavities 14 of the adjacent support plates 1, so that the penetrating support layers at each folding position are rigidly supported on the plane, thereby further strengthening the firmness of each folding part 2 and each support plate 1 on the same plane and further protecting the flexible display screen 20. When the folding device 10 is in a folded state, the double T-shaped auxiliary support plates 15 in each folding region complete a folding task by sliding in the T-shaped sliding cavities 14 under the pushing action of the inserting support layers 22 and the action of the tension springs 172 or the compression springs 173, and cover and hide the inserting support layers 22.

The stack of support panels 1 may in other embodiments be a fully folded-out rolled stack, each of the folded parts 2 having a length which varies with the shape. In this embodiment, the flexible display screen 20 is folded to form a support space with a reduced volume, and the completely unfolded penetrating support layer 22 is adapted to move between the springs 2211 and 2211 to approach each other to form a support inner arc surface; after the folded-in region is folded, the volume of the space supported by the flexible display screen 20 needs to be enlarged, and then the penetrating support layer 22 which is not completely unfolded is adapted to move away from the springs 2211 and 2211, and under the combined action of the elastic force of the metal strip 222 with a certain diameter and length and the tensile force of the flexible cloth 211, a support extrados surface capable of safely folding-in the flexible display screen 20 is formed.

When the flexible display screen 20 can be made to have a thickness of 0.1 mm to 0.66 mm and a folding radius of 1 mm, the spring can be made to have a wire diameter of 0.15 mm and a radius of 0.5 mm, since the support plate 1 can be, but not limited to, a thin plate, since the spring 2211 of the folding part 2 has a simple structure, and the diameter of the spring 2211 can be made smaller, and the volume of the spring can be further reduced by a preferable winding manner, so that the folding can be realized in a manner of a thinner thickness.
