[0002] Large-screen terminals can provide users with better Internet access and audio-visual gaming experience, but are not easy to carry; small-screen terminals are easy to carry, but the experience is not good enough when surfing the Internet and playing games. Therefore, there is a need for a terminal that can change the display area size according to user needs, which can combine the sensory enjoyment of a large screen with the portability of a small screen.

[0003] To meet this demand, flexible screens and transformable smart terminals have emerged. Flexible screens can bend freely, freeing display-based smart terminal products from the inherent rigid structure. This allows flexible screen terminals to adjust the actual display area to suit user needs, combining the sensory enjoyment of a large screen with the portability of a small screen. This has become a key development direction for smart terminal products.

[0004] Current flexible screen terminals and folding screen terminals all bend the flexible screen through manual operation. During the bending process, the flexible screen may be damaged due to excessive force applied by the user. At the same time, due to the lack of convenience and technological sense of manual operation, the user experience is poor. Summary of the Invention

[0031] Figure 1 A schematic structural diagram showing the flexible screen support device in an embodiment of the present application in a flattened state. Figure 2 Schematic diagram showing the structure of the flexible screen support device in a bent state in an embodiment of the present application. Figures 1 to 2, an embodiment of the present application provides a flexible screen support device, which is applied to bendable flexible screen products, including but not limited to smart phones, smart watches, smart tablets, etc. The flexible screen support device includes a bending plate 1, a connecting rope 2 and a driving mechanism 3. The bending plate 1 has a surface for supporting the flexible screen, which can be bent so as to have a bent state and a flattened state, so that the flexible screen bends and flattens accordingly. The bending plate 1 includes a plurality of support blocks 11 hinged in sequence, and at least one side surface of the support blocks 11 together constitutes a surface for supporting the flexible screen. The upper width of each support block 11 gradually decreases, that is, the upper width of the support block 11 is smaller than its lower width. When the bending plate 1 is in a flattened state, a rotation gap is formed between the upper parts of the two adjacent support blocks 11; when the bending plate 1 is in a bent state, the upper parts of the two adjacent support blocks 11 contact each other. Through the mutual cooperation of the multiple support blocks 11 hinged in sequence, the bending plate 1 is bent and deformed, thereby realizing the conversion of the flexible screen support device between the bent and flattened states. It should be noted that the "upper part" described in the embodiment of the present application refers to Figure 1 The upper part of the middle support block 11, and the "lower part" refers to Figure 1 The lower portion of the middle support block 11 is used for ease of description only and does not indicate or imply that the support block 11 must have a specific orientation.

[0032] In the embodiment of the present application, the connecting rope 2 is preferably a thin rope made of a soft elastic material, with a portion of the connecting rope 2 sequentially passing through the upper portion of each support block 11, and another portion sequentially passing through the lower portion of each support block 11. When the bending plate 1 is in a flattened state, by tightening the upper portion of each support block 11 and relaxing the lower portion of each support block 11 by the connecting rope 2, the upper portions of each support block 11 in the bending plate 1 can be pressed together in sequence, a gap appears at the lower portion of each support block 11, and the bending plate 1 bends upward; when the bending plate 1 is in a bent state, by tightening the lower portion of each support block 11 and relaxing the upper portion of each support block 11 by the connecting rope 2, the lower portions of two adjacent support blocks 11 in the bending plate 1 can be pressed together in sequence, a gap appears at the upper portion, and the bending plate 1 is flattened downward. Furthermore, the connecting rope 2 of this embodiment is also connected to the driving mechanism 3, so that it can be tightened or relaxed under the drive of the driving mechanism 3; the driving mechanism 3 is connected to the control device signal, and by cooperating with the software control system of the smart terminal, it can realize one-button control of the bending or flattening of the flexible screen.

[0033] In the embodiment of the present application, the bending angle of the flexible screen support device can be set in advance, and can be set specifically according to the material properties of the flexible screen, the user's usage scenario, etc., to ensure that the flexible screen can maintain an appropriate bending radius when bending, and will not be damaged due to a bending radius that is too small or too much force; and the flexible screen support device can provide reliable rigid support for the flexible screen when flattened. Of course, the above-mentioned preset bending angle is not limited to one, and multiple bending angles that meet the requirements of safe use can also be set. The user can realize the conversion of the flexible screen between multiple different bending states through the software control system. The present application realizes the automatic bending and automatic flattening of the flexible screen, ensures the safety of the flexible screen, enhances the convenience and intelligence of the product, makes the product more technological, and helps to improve the user experience.

[0034] Furthermore, the driving mechanism 3 of this embodiment is preferably a motor, and the connecting rope 2 is a whole rope, one end of which is fixed to the upper part of the support block 11 at the end (i.e., the end away from the driving mechanism 3), and the other end is fixed to the lower part of the support block 11 at the end, and the middle part of the connecting rope 2 is fixed to the output shaft of the motor, so that when the motor rotates, one end of the connecting rope 2 can be tightened and the other end can be relaxed. Further preferably, the connecting ropes 2 and the motors of this embodiment are provided with at least two groups, and at least two groups of connecting ropes 2 are evenly distributed along the length direction of the support block 11, and each group of connecting ropes 2 is connected to each group of motors in a one-to-one correspondence. This arrangement can improve the movement balance of the bending plate 1 to form better support for the flexible screen. Of course, in other embodiments, only one group of motors can be provided, and a group of motors can cooperate with the transmission system to drive multiple groups of connecting ropes 2 to move, thereby simplifying the structure and saving costs.

[0035] Figure 3 A schematic diagram of the exploded structure of the support block 11 and the connecting rod 12 in the embodiment of the present application is shown. Figure 4 FIG. 1 is a schematic cross-sectional view of the support block 11 in an embodiment of the present application. Figures 3 and 4In this embodiment, preferably, the support block 11 is a columnar structure, and the shapes and sizes of the multiple support blocks 11 are the same. Specifically, the upper cross-sectional shape of the support block 11 is a trapezoid, and the lower cross-sectional shape is a rectangle, and the length of the bottom side of the trapezoid is the same as the length of the top side of the rectangle, that is, the entire cross-sectional shape of the support block 11 is a hexagon. In this embodiment, the lower end face of the support block 11 is preferably used to fit with the flexible screen. The above-mentioned trapezoidal structure can not only make the upper width of the support block 11 smaller than its lower width, but also increase the contact area between the lower end face of the support block 11 and the flexible screen, thereby improving the support effect of the support block 11 for the flexible screen. Further preferably, the upper cross-sectional shape of the support block 11 is an isosceles trapezoid, so that the two sides of the support block 11 are more evenly stressed, better improving the folding performance of the bending plate 1, and thus improving the folding performance of the smart terminal. In this embodiment, the degree of bending of the bending plate 1 is related to the shape, size, number and size of the rotation gap of the support block 11. For example, the degree of foldability of the support block 11 can be adjusted by adjusting the base angle of the isosceles trapezoid. The larger the base angle of the isosceles trapezoid, the smaller the foldability of a single support block 11, and the more support blocks 11 are required to achieve the same degree of bending in the entire bending plate 1. Of course, in specific applications, those skilled in the art can set the shape and number of the support blocks 11 according to actual needs, and are not limited to this embodiment.

[0036] Continue to refer Figure 3 The bending plate 1 of this embodiment further includes a connecting rod 12. The side wall of the support block 11 is provided with a mounting hole 111. The connecting rod 12 is passed through the mounting holes 111 of two adjacent support blocks 11. In this embodiment, the connecting rod 12 is used as a rotating shaft to hinge the two adjacent support blocks 11. The structure is simple and the installation is convenient. Of course, in other embodiments, other methods can also be used to achieve the hinge between the support blocks 11, and this is not limited to this embodiment. Furthermore, the support blocks 11 and the connecting rod 12 of this embodiment are both made of hard materials, such as metal or hard plastic, to increase the overall support performance and bending reliability of the bending plate 1.

[0037] Figure 5 A schematic diagram of the bending process of the flexible screen support device in an embodiment of the present application is shown. Figure 6 Schematic diagram of the flattening process of the flexible screen support device in the embodiment of the present application is shown. Figure 5-Figure 6 , the working principle of this embodiment is as follows:

[0038] like Figure 5 As shown, when the whole machine is in a flat state and needs to be bent, the software system controls the output shaft of the motor to move along the Figure 5The connecting rope 2 rotates counterclockwise in the direction indicated by the middle arrow, thereby driving the connecting rope 2 to rotate counterclockwise along with the output shaft of the motor. The connecting rope 2 pulls the upper half of the bending plate 1 to tighten and the lower half to loosen. Since the upper half of the support block 11 is a trapezoidal structure, the upper halves of each support block 11 are pressed together in pairs, so that the entire bending plate 1 is automatically bent. The final state is as follows Figure 2 shown.

[0039] like Figure 6 As shown, when the whole machine is in a bent state and needs to be flattened, the software system controls the output shaft of the motor to move along the Figure 6 The connecting rope 2 rotates clockwise in the direction indicated by the arrow, thereby driving the connecting rope 2 to rotate clockwise along with the output shaft of the motor. The connecting rope 2 pulls the lower half of the bending plate 1 to gradually tighten, and the upper half to gradually loosen. Since the lower half of the support block 11 is a rectangular structure, the lower halves of the support blocks 11 are pressed together in pairs, so that the entire bending plate 1 is automatically flattened. The final state is as follows Figure 1 shown.

[0040] The embodiment of the present application also provides a smart terminal, including a flexible screen and the above-mentioned flexible screen support device, and the flexible screen is arranged on the flexible screen support device. Preferably, the flexible screen is adhered to the lower end surface of each support block 11 by bonding. The smart terminal of this embodiment can be a smart phone, a smart watch or a smart tablet, etc. For example, when the smart terminal is a smart watch, the smart watch can be bent and folded into the shape of a bracelet through the control of the software interface to facilitate the user to wear the watch on the wrist. This embodiment realizes the automatic bending and flattening of the smart terminal, avoids damage to the flexible screen of the smart terminal caused by manual operation, improves the convenience and intelligence of the product, and helps to improve the user experience.
