[0023] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] The electronic device, tensioning mechanism and installation method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0026] Please refer to Figure 1 to Figure 2 , Figure 1 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application, Figure 2 The cross-sectional diagram of an electronic device provided in an embodiment of the present application is shown in FIG. Figure 1 and Figure 2As shown, an embodiment of the present application provides an electronic device, which includes a flexible display screen 5, a first shell 1, a second shell 2, a folding mechanism 4 and a tensioning mechanism 3; wherein the first shell 1 and the second shell 2 are connected by the folding mechanism 4, and the first shell 1 and the second shell 2 can rotate relative to each other, so that the electronic device can switch between a folded state and a flattened state; that is, the folding mechanism 4 is arranged between the first shell 1 and the second shell 2, and the relative rotation between the first shell 1 and the second shell 2 can be achieved by the folding mechanism 4. For example, the folding mechanism 4 can be in the form of a hinge, a transmission shaft, a gear, etc. The flexible display screen 5 is arranged on the first shell 1, the second shell 2 and the folding mechanism 4, and the area opposite to the flexible display screen 5 and the folding mechanism 4 is the bending area; that is, the first shell 1, the second shell 2 and the folding mechanism 4 are supported below the flexible display screen 5, and the flexible display screen 5 is fixedly connected to the first shell 1 and the second shell 2. Optionally, the flexible display screen 5 can be bonded to the first shell 1 and the second shell 2 by double-sided adhesive. When the first shell 1 and the second shell 2 rotate relative to each other, the area of ​​the flexible display screen 5 opposite to the first shell 1 and the area opposite to the second shell 2 will also rotate relative to each other, thereby enabling the flexible display screen 5 to switch between a folded state and an unfolded state.

[0027] Among them, when the first shell 1 and the second shell 2 rotate relative to each other, the bending zone of the flexible display screen 5 will also bend and deform accordingly. After a large number of folding times, there will be a deeper crease in the bending zone, thereby affecting the display effect of the flexible display screen 5, and then affecting the user's viewing experience. Therefore, in the embodiment of the present application, a tensioning mechanism 3 is also provided between the folding mechanism 4 and the flexible display screen 5. The tensioning mechanism 3 is connected to the folding mechanism 4. When the electronic device is in a flattened state, the tensioning mechanism 3 has elastic deformation and generates elastic force, that is, it has a tendency to restore to the original state. At this time, the tensioning mechanism 3 contacts the bending zone of the flexible display screen 5, so that the tensioning mechanism 3 supports the bending zone, and then the bending zone of the flexible display screen 5 has a tendency to restore to a plane, and finally the crease in the bending zone of the flexible display screen 5 becomes shallower or even disappears, thereby achieving the purpose of improving the crease.

[0028] Therefore, in the embodiment of the present application, a tensioning mechanism 3 is provided between the folding mechanism 4 and the flexible display screen 5 of the electronic device, and the tensioning mechanism 3 is connected to the folding mechanism 4, so that when the electronic device is in a flattened state, the tensioning mechanism 3 contacts the bending area through the tensioning mechanism 3 to support the bending area, which is equivalent to forming a planar support under the bending area, thereby improving the flatness of the flexible display screen 5 when the electronic device is in a flattened state, improving the crease phenomenon, improving the display effect of the flexible display screen 5, and then improving the user experience.

[0029] In some embodiments of the present application, the tensioning mechanism 3 may be made of metal material, such as titanium alloy, stainless steel material, etc. The tensioning mechanism is a sheet-like structure, and the tensioning mechanism includes a first non-through hole area, a second non-through hole area and a through hole area. The first non-through hole area and the second non-through hole area are connected by the through hole area, and at least two through holes are provided in the through hole area. Since the through hole area of ​​the tensioning mechanism of the metal material has at least two through holes, the strength of the through hole area will be lower than the strength of the first through hole area and the second through hole area of ​​the tensioning mechanism. In other words, the through hole area of ​​the tensioning mechanism can be bent or stretched, so as to have a tensioned state or a non-tensioned state. When the tensioning mechanism is arranged on the folding screen, the through hole area of ​​the tensioning mechanism faces the folding mechanism, so that the electronic device can be folded. When the electronic device is in a flattened state, the through hole area of ​​the tensioning mechanism can contact the bending area of ​​the flexible display screen. Since the tensioning mechanism is made of metal material and the through hole area has a certain strength, it can provide support for the bending area of ​​the flexible display screen, thereby reducing the creases in the bending area of ​​the flexible display screen due to the increase in the number of folding times.

[0030] In some embodiments of the present application, the tensioning mechanism 3 may be an elastic material, such as any one of a spring sheet, a rubber sheet, and a silicone sheet, or an elastic net formed by a plurality of elastic ropes, so that the elastic material can have an untensioned state and a tensioned state. As long as the electronic device can contact the bending area when it is in a flat state and can support the bending area so that the crease of the bending area is improved, the embodiments of the present application are not specifically limited.

[0031] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a tensioning mechanism provided in an embodiment of the present application. Figure 3As shown, in some embodiments of the present application, the tensioning mechanism 3 is a sheet-like structure, for example, a regular rectangle, and the tensioning mechanism 3 includes a first non-through hole area 31, a second non-through hole area 32 and a through hole area 33, wherein the first non-through hole area 31 and the second non-through hole area 32 are connected by the through hole area 33, that is, the first non-through hole area 31 and the second non-through hole area 32 are arranged on both sides of the through hole area 33. At least two through holes are provided in the through hole area 33. By providing through holes in the through hole area 33, the through hole area 33 of the tensioning mechanism 3 can be easily bent when the electronic device is in a folded state. In the flattened state, due to the existence of the through hole area, a certain strength is provided, thereby effectively supporting the bending area of ​​the flexible display screen. In addition, since the through holes in the through hole area are hollow or filled with other materials that are conducive to bending, it is also helpful to reduce the weight of the tensioning mechanism 3, and then reduce the weight of the entire electronic device. Optionally, the through holes in the through hole area 33 can be formed by an etching process, and the specific material of the tensioning mechanism 3 can be a metal material or a non-metal material, etc., as long as it can provide support for the bending area of ​​the flexible display screen when the electronic device is in a flat state, the embodiment of the present application does not make specific limitations.

[0032] In some embodiments of the present application, the through hole area 33 includes a plurality of through holes arranged in rows, and any two adjacent rows of through holes are staggered with each other. In other words, the through holes in the through hole area 33 are arranged in adjacent rows, and any two adjacent rows of through holes are staggered with each other, thereby preventing the flexible display screen from sinking in the through hole area of ​​the tensioning mechanism, and making the tensioning mechanism 3 have a better supporting effect on the flexible display screen 5 when the electronic device is in a flattened state, thereby improving the improvement effect of the crease in the bending area.

[0033] In other embodiments of the present application, the cross-sectional shape of the through hole can be any one of a circle, an ellipse, and a polygon, wherein the polygon can be a regular polygon, or other polygons other than a regular polygon, for example, the polygon can be a triangle, a quadrilateral, a hexagon, etc. By selecting different cross-sectional shapes of the through hole, the deformation effect of the through hole area 33 of the tensioning mechanism 3 can be changed, so that a through hole with a cross-sectional shape that meets the requirements can be selected according to actual needs.

[0034] In some embodiments of the present application, the ratio of the width of the through-hole area 33 to the width of the tensioning mechanism 3 in the initial state is 0.5 to 0.95. The width of the through-hole area 33 is the distance between the first non-through-hole area 31 and the second non-through-hole area 32, and the width of the tensioning mechanism 3 in the initial state is the width of the tensioning mechanism 3 when it is in a planar state and is not elastically deformed by external force. By setting the ratio of the width of the through-hole area 33 to the width of the tensioning mechanism 3 in the initial state to 0.5 to 0.95, the deformation amount of the electronic device when it is in a flattened state can be appropriate, and then the support effect of the bending area support is better.

[0035] Please refer to Figure 4 and Figure 5 , Figure 4 A schematic diagram of a folding mechanism provided in an embodiment of the present application, Figure 5 This is a cross-sectional schematic diagram of the folding mechanism provided in the embodiment of the present application. Figure 4 and Figure 5 As shown, in some embodiments of the present application, the folding mechanism 4 includes a first support plate 41, a second support plate 43 and a hinge mechanism 42, wherein one end of the hinge mechanism 42 is connected to the first support plate 41, and the other end of the hinge mechanism 42 is connected to the second support plate 43, that is, the hinge mechanism 42 can be divided into two parts along its axial direction, one part of which is connected to the first support plate 41, and the other part is connected to the second support plate 43. In addition, the first shell 1 is connected to the hinge mechanism 42 through the first support plate 41, and the second shell 2 is connected to the hinge mechanism 42 through the second support plate 43, thereby, the first shell 1 and the second shell 2 can realize relative movement between the two through the movable link of the hinge mechanism 42.

[0036] Among them, if the folding mechanism 4 is directly opposite to the bending zone of the flexible display screen 5, the flatness requirements for the first support plate 41, the second support plate 43 and other components in the folding mechanism 4 are relatively high, thereby increasing the design and processing difficulty of the folding mechanism 4. In the embodiment of the present application, a tensioning mechanism 3 is arranged between the folding mechanism 4 and the bending zone, and the plane formed by the tensioning mechanism 3 plays a good supporting role for the bending zone, which can reduce the flatness requirements for the first support plate 41, the second support plate 43 and other components in the folding mechanism 4 and the cost of the folding mechanism 4.

[0037] In some other embodiments of the present application, the specific connection mode of the tensioning mechanism 3 and the folding mechanism 4 can be: the first non-through hole area 31 of the tensioning mechanism 3 is connected to the first support plate 41, and the second non-through hole area 32 is connected to the second support plate 43, wherein the through hole area 33 is opposite to the hinge mechanism 42. That is to say, the two ends of the tensioning mechanism 3 are respectively connected to the first support plate 41 and the second support plate 43 of the folding mechanism 4. When the electronic device is in a flattened state, the two ends of the tensioning mechanism 3 will also follow the first support plate 41 and the second support plate 43 to be flattened, which will generate a tensile force on the through hole area 33 of the tensioning mechanism 3 and may cause a certain deformation. Then, the tensioning mechanism 3 will have a force from the first non-through hole area and the second non-through hole area to the through hole area. Since the through hole area 33 is in contact with the bending area of ​​the flexible display screen 5, a supporting force will be formed on the bending area, so that the bending area also has a tendency to return to a plane, thereby improving the crease of the bending area. Optionally, the tensioning mechanism 3 and the folding mechanism 4 can be bonded by double-sided adhesive.

[0038] In some embodiments of the present application, the ratio of the width of the tensioning mechanism 3 in the initial state to the width of the folding mechanism 4 is 0.6 to 0.9. Among them, the width of the tensioning mechanism 3 in the initial state is the width of the tensioning mechanism 3 when it is in a plane state and is not elastically deformed by external force. The width of the folding mechanism 4 can be the distance between the side edge of the first support plate 41 close to the first shell 1 and the side edge of the second support plate 43 close to the second shell 2, and the width direction of the folding mechanism 4 is the same as the width direction of the tensioning mechanism 3. The ratio of the width of the tensioning mechanism 3 in the initial state to the width of the folding mechanism 4 is set to 0.6 to 0.9, so that when the first support plate 41 and the second support plate 43 rotate relative to each other on both sides of the hinge mechanism 42, a larger pulling force can be applied to the tensioning mechanism 3, so that the deformation of the tensioning mechanism 3 when the electronic device is in a flattened state is appropriate, and then the support effect of the bending zone support is better.

[0039] In other embodiments of the present application, the thickness of the tensioning mechanism 3 is in the range of 0.05 mm to 2 mm. By setting the thickness of the tensioning mechanism 3 to the above range, it can be ensured that the tensioning mechanism 3 can generate a good elastic force when a tensile force is applied, thereby providing a good support for the bending area of ​​the flexible display screen 5.

[0040] Please refer to Figures 6 to 9 , Figure 6 This is one of the schematic diagrams of the crease of the flexible display screen before improvement provided in the embodiment of the present application, Figure 7 This is one of the schematic diagrams of the crease of the improved flexible display screen provided in the embodiment of the present application, Figure 8 The second schematic diagram of the crease of the flexible display screen before improvement provided in the embodiment of the present application, Fig. 9 The second schematic diagram of the fold of the improved flexible display screen provided in the embodiment of the present application. Figure 6 and Figure 8 As shown, in the prior art, the flexible display screen 5 has obvious creases after being folded multiple times, and the creases are mainly concentrated in the bending area of ​​the flexible display screen 5; Figure 7 , Fig. 9 As shown, after using the tensioning mechanism 3 in the embodiment of the present application, the creases on the flexible display screen 5 are significantly improved by utilizing the supporting effect of the tensioning mechanism 3 on the flexible display screen 5.

[0041] In the embodiments of the present application, illustratively, the electronic device may be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a personal computer (PC), etc., and the embodiments of the present application do not make specific limitations.

[0042] In summary, in the embodiments of the present application, a tensioning mechanism is provided between the folding mechanism and the flexible display screen of the electronic device, and the tensioning mechanism is connected to the folding mechanism, so that the tensioning mechanism is deformed and generates elastic force when the electronic device is in a flattened state, and the tensioning mechanism contacts the bending zone to support the bending zone, thereby improving the flatness of the flexible display screen when the electronic device is in a flattened state, improving the crease phenomenon, improving the display effect of the flexible display screen, and then improving the user experience.

[0043] On the other hand, an embodiment of the present application further provides a tensioning mechanism, which has a sheet-like structure. The tensioning mechanism includes a first non-through hole area, a second non-through hole area and a through hole area. The first non-through hole area and the second non-through hole area are connected by the through hole area, and at least two through holes are opened in the through hole area.

[0044] The tensioning mechanism in the embodiment of the present application can be arranged between the bending zone and the folding mechanism of the flexible display screen, and then when the electronic device is in a flat state, the tensioning mechanism contacts the bending zone to support the bending zone, thereby improving the flatness of the flexible display screen when the electronic device is in a flat state, improving the crease phenomenon, improving the display effect of the flexible display screen, and then improving the user experience.

[0045] In some embodiments of the present application, optionally, the through-hole area includes a plurality of through-holes arranged in rows, and the through-holes in any two adjacent rows are staggered with each other.

[0046] In some embodiments of the present application, optionally, the cross-sectional shape of the through hole is any one of a circular shape, an elliptical shape, and a polygonal shape.

[0047] In some embodiments of the present application, optionally, the ratio of the width of the through hole area to the width of the tensioning mechanism in an initial state is 0.5 to 0.95.

[0048] In some embodiments of the present application, optionally, the tensioning mechanism is made of metal material.

[0049] The specific structural composition and working principle of the tensioning mechanism provided in the embodiment of the present application can refer to the tensioning mechanism described in the above-mentioned electronic device embodiment, and can achieve the same technical effect. To avoid repetition, they will not be described here.

[0050] Please refer to Fig.10 , Fig.10 A schematic diagram of a process flow of an installation method provided in an embodiment of the present application. Fig.10 As shown, another embodiment of the present application further provides an installation method, which is applied to the electronic device in any of the above embodiments, and the method includes the following steps:

[0051] Step 101: Connect one end of the tensioning mechanism to one end of the folding mechanism;

[0052] Step 102: Folding the electronic device to a target angle;

[0053] Step 103: Connect the other end of the tensioning mechanism to the other end of the folding mechanism when the tensioning mechanism is not tensioned, so that the tensioning mechanism is in a tensioned state when the electronic device is in a flattened state, and the tensioning mechanism contacts the bending area of ​​the flexible display screen to support the bending area.

[0054] In an embodiment of the present application, the electronic device includes a first shell, a second shell and a folding mechanism; wherein the first shell and the second shell are connected by the folding mechanism, and the first shell and the second shell can rotate relative to each other, so that the electronic device can switch between a folded state and a flattened state; that is, the folding mechanism is arranged between the first shell and the second shell, and relative rotation between the first shell and the second shell can be achieved through the folding mechanism. Exemplarily, the folding mechanism can be in the form of a hinge, a transmission shaft, a gear, etc.

[0055] In some embodiments, optionally, the folding mechanism includes a first support plate, a second support plate and a hinge mechanism, one end of the hinge mechanism is connected to the first support plate, the other end of the hinge mechanism is connected to the second support plate, and the first shell is connected to the hinge mechanism through the first support plate, and the second shell is connected to the hinge mechanism through the second support plate.

[0056] In this embodiment, the electronic device further includes a tensioning mechanism. After the assembly of the above structure is completed, one end of the tensioning mechanism is connected to one end of the folding mechanism. Optionally, the tensioning mechanism is a sheet-like structure, and the tensioning mechanism includes a first non-through hole area, a second non-through hole area and a through hole area. The first non-through hole area and the second non-through hole area are connected through the through hole area, and at least two through holes are provided in the through hole area. Among them, one end of the tensioning mechanism is the first non-through hole area, and one end of the folding mechanism is the first support plate. The connection between one end of the tensioning mechanism and one end of the folding mechanism is the connection between the first non-through hole area of ​​the tensioning mechanism and the first support plate of the folding mechanism. Optionally, the tensioning mechanism and the folding mechanism can be bonded by double-sided tape.

[0057] In this embodiment, after connecting one end of the tensioning mechanism to one end of the folding mechanism, the electronic device can be folded to a target angle. For example, the target angle can be selected in the range of 90° to 170°. Thereafter, the other end of the tensioning mechanism is connected to the other end of the folding mechanism when the tensioning mechanism is not tensioned. Thus, by folding the electronic device to the target angle, the other end of the tensioning mechanism can be easily connected to the other end of the folding mechanism, thereby eliminating the cumbersome process of connecting the other end of the tensioning mechanism to the other end of the folding mechanism by pulling the tensioning mechanism with external force, and also avoiding the problem of inconsistent deformation of the tensioning mechanism caused by unbalanced external force when external force is applied, thereby ultimately ensuring the improvement effect of the tensioning mechanism on the crease in the bending zone.

[0058] Specifically, the other end of the tensioning mechanism is the second non-through hole area, and the other end of the folding mechanism is the second support plate. The other end of the tensioning mechanism is connected to the other end of the folding mechanism, that is, the second non-through hole area of ​​the tensioning mechanism is connected to the second support plate of the folding mechanism. Optionally, the tensioning mechanism and the folding mechanism can be bonded by double-sided tape.

[0059] In this embodiment, after the tensioning mechanism is installed, the flexible display screen can be arranged on the first shell, the second shell and the folding mechanism, and the tensioning mechanism is located between the flexible display screen and the folding mechanism, and the area of ​​the flexible display screen opposite to the folding mechanism is the bending area. When the first shell and the second shell rotate relative to each other, the area of ​​the flexible display screen opposite to the first shell and the area opposite to the second shell will also rotate relative to each other, thereby realizing the switching of the flexible display screen between the folded state and the flattened state.

[0060] In an embodiment of the present application, after the two ends of the tensioning mechanism are respectively connected to the two ends of the folding mechanism, the tensioning mechanism can be made to contact the bending area of ​​the flexible display screen when the electronic device is in a flattened state to support the bending area.
