Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a supporting assembly and an electronic equipment. Background Art

[0002] At present, flexible screens are widely used in many different types of foldable devices. Under different usage requirements, users can fold and unfold the foldable devices to meet different needs of users. For example, when a user needs to carry a foldable device with him, he can fold it to reduce its volume, thereby improving portability. When a user is using a foldable device, he can unfold it to provide a larger display area and operation area, thereby improving the convenience of use. In practical applications, a support component is usually set on the back of the flexible screen, and the support component can effectively support the flexible screen. When the flexible screen is in a flattened state, the support component can ensure the flatness of the flexible screen to improve the display effect of the flexible screen. In addition, when the flexible screen is touched or pressed, the support component can also effectively prevent the flexible screen from bending and other undesirable conditions. In addition, when the foldable device is folded, the support component can also bend as the foldable device is folded, thereby effectively supporting the flexible screen. However, in the current support component, there are problems such as poor use effect and complex manufacturing process, which makes the support component have poor compressive performance and poor deformation ability. Summary of the invention

[0003] The present application provides a support component and an electronic device with a simple structure and good compression resistance and deformation ability.

[0004] In the first aspect, the present application provides a support assembly for supporting a flexible screen. The flexible screen includes a display surface and a back surface opposite to the display surface, and the support assembly is arranged on the back surface. The support assembly includes a first plate body, and the first plate body has a plurality of arc plates, each of which extends along a first direction. A plurality of arc plates are arranged in sequence along a second direction, and the first direction and the second direction are both parallel to the back surface, and the first direction is perpendicular to the second direction, and the concave side of each arc plate faces the back surface of the flexible screen, or the concave side of each arc plate faces away from the back surface of the flexible screen, so as to effectively support the flexible screen and ensure the bendability of the support assembly. Among them, the arc plate is an elastic plate, and the arc plate can ensure the support and deformation recovery ability of the first plate body through its own elastic force. In the support assembly provided in the present application, the first plate body includes a plurality of arc plates, so that the first plate body has good compressive resistance, can effectively support the flexible screen, and thus ensure the flatness of the flexible screen. When the display surface of the flexible screen is subjected to a pressing force, the pressing force is transmitted to the first plate body. The arc-shaped plate with an arc-shaped cross section has good compressive resistance and can effectively support the flexible screen to prevent the flexible screen from being dented. In addition, the first plate body also has good self-supporting ability and good bendability, so it can ensure the flatness and bendability of the support component and the flexible screen.

[0005] In one example, each curved plate has two side edges parallel to the first direction, and the side edges of the plurality of curved plates are all located in a first plane, and the first plane is parallel to the back surface of the flexible screen, thereby effectively improving the flatness of the first plate body on the concave side. When the flexible screen is disposed on the concave side of the first plate body, the flatness performance of the flexible screen can be improved.

[0006] In one example, the vertices of the plurality of curved plates are all located in the second plane, and the second plane is parallel to the back surface of the flexible screen. Thus, the flatness of the first plate body on the convex side can be effectively improved. When the flexible screen is arranged on the convex side of the first plate body, the flatness performance of the flexible screen can be improved.

[0007] In one example, the curvature of each curved plate may be the same, so that each curved plate has substantially consistent support and bendability.

[0008] In one example, the plurality of curved plates include at least two curved plates with different curvatures, so that the curved plates with different curvatures have different support and bending properties, and can meet different usage requirements.

[0009] In one example, in at least one curved plate, along the first direction, the curvature of the curved plate is the same, so that different regions of the curved plate have substantially consistent support and bendability.

[0010] In one example, in at least one curved plate, the curved plate has regions with different curvatures along the first direction, so that regions with different curvatures have different support and bending properties, and can meet different usage requirements.

[0011] In one example, the concave side of the arc-shaped plate is filled with elastic material, which can ensure the support and deformation recovery capabilities of the first plate body.

[0012] In one example, each of the multiple arc-shaped plates is fixedly connected to one or more adjacent arc-shaped plates, which can avoid using additional connecting members to connect two adjacent support plates, and has the characteristic of simple structure.

[0013] In one example, the first plate body further includes at least one connecting plate, each connecting plate is located between the two arc-shaped plates and is respectively connected to one side of the two arc-shaped plates. That is, two adjacent arc-shaped plates can be fixedly connected by the connecting plate, and a reliable connection between the two arc-shaped plates can be achieved by reasonably setting the structural shape of the connecting plate.

[0014] In one example, the first plate body has a plurality of connecting plates. The connecting plates are flat plates, and the plurality of connecting plates are all located in the first plane. The flatness of the first plate body can be effectively improved by providing a flat connecting plate. When the flexible screen is provided on one side of the connecting plate, the connecting plate can effectively support the flexible screen, thereby improving the plane performance of the flexible screen.

[0015] In one example, the width of each connecting plate can be the same. Alternatively, at least two connecting plates with different widths are included among the multiple connecting plates. By reasonably setting the width of the connecting plate, the distance between two adjacent arc-shaped plates can be reasonably adjusted, which has good flexibility.

[0016] In one example, in at least one connecting plate, the width of the connecting plate is the same along the first direction. Alternatively, in at least one connecting plate, the connecting plate has regions with different widths along the first direction. Along the first direction, when the widths of the arc-shaped plates on both sides of the connecting plate are different, the connecting plate can be well adapted to the arc-shaped plates, thereby facilitating the fixed connection and effective connection between the two adjacent arc-shaped plates.

[0017] In one example, the connection plate may have at least one hollow portion. Specifically, the hollow portion may be a slit or a notch. When the hollow portion is a slit, the slit extends along the first direction and / or the second direction. The slit can reduce the weight of the connection plate and can also provide an effective collapse space for the deformation of the connection plate, which is conducive to ensuring the reliability of the first plate body.

[0018] In one example, when the hollow portion is a notch, and there are multiple notches, in the first direction, the multiple notches are arranged in sequence and at intervals. Alternatively, in the second direction, the multiple notches can be arranged in a staggered manner. The notches can reduce the weight of the connecting plate, and can also provide an effective collapse space for the deformation of the connecting plate, which is conducive to ensuring the reliability of the first plate body.

[0019] In one example, the support assembly may further include a second plate. The second plate may be disposed on one side of the outer arc surface of the first plate, and the second plate may be in contact with the top surface of the outer arc surface of the first plate. The second plate may be a flat plate, thereby providing a flat surface and improving the surface support of the support assembly. When the flexible screen is disposed on one side of the second plate, the plate surface of the second plate may provide effective planar support for the flexible screen, thereby ensuring the flatness of the flexible screen. The second plate may be made of a flexible material, that is, a non-rigid material, so that it can be bent with the flexible screen; for example, it may be implemented using thin metal plates of various materials, which are not described in detail in this application.

[0020] In one example, the gap between the second plate and the first plate can be filled with an elastic material. The elastic material can be provided to connect the second plate and the first plate. In addition, the elastic material can also improve the elasticity of the support assembly.

[0021] In the second aspect, the present application also provides an electronic device, including a bendable mechanism, a flexible screen and the above-mentioned support assembly. The bendable mechanism is connected to the support assembly and / or the flexible screen, and is used to bend the flexible screen and the support assembly around the virtual axis. Wherein, the virtual axis is parallel to the second direction. In actual use, when the electronic device is in a flattened state, the support assembly can keep the electronic device in a flattened state to a certain extent under the action of the curved plate, so that the use effect of the electronic device can be guaranteed. In addition, since the virtual axis is parallel to the second direction, when the electronic device is bent, the bending force will first reduce the curvature of the curved plate, and then the curved plate can be bent and deformed, so the electronic device has better self-supporting ability and better bendability. Wherein, the virtual axis is located on the concave side of the curved plate. That is to say, the bendable mechanism can bend the curved plate on the concave side. Based on the structural characteristics of the curved plate, the curved plate is easier to bend on the concave side, so the bendability of the electronic device can be guaranteed.

[0022] In one example, the electronic device may be a foldable device. The foldable mechanism may include a first shell, a second shell, and a hinge, the hinge is connected between the first shell and the second shell, and the first shell and the second shell can be folded or unfolded relative to each other around a virtual axis. The support assembly is connected to the first shell and the second shell. Alternatively, the flexible screen is connected to the first shell and the second shell, or the flexible screen and the support assembly are both connected to the first shell and the second shell.

[0023] In one example, the electronic device may be a rollable device, wherein the bending mechanism includes a winding shaft, and the virtual axis is the axis of the winding shaft. The winding shaft is connected to at least one of the flexible screen and the support assembly, and is used to wind the flexible screen and the support assembly around the outer circumference of the winding shaft.

[0056] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] In order to facilitate understanding of the support assembly provided in the embodiment of the present application, its application scenario is first introduced below.

[0058] The support component provided in the embodiment of the present application can be applied to a foldable device or a rollable device. The support component can be deformed according to the usage form of the foldable device or the rollable device, thereby meeting the needs of different usage scenarios.

[0059] Specifically, a foldable device is an electronic device that can change its shape by folding, rotating, etc. Under different usage requirements, users can fold and unfold the foldable device to meet different needs of users.

[0060] When a user needs to carry a foldable device with him / her, he / she can fold it to reduce its volume, thereby improving portability. When a user is using a foldable device, he / she can unfold it to provide a larger display area and operation area, thereby improving convenience. In practical applications, foldable devices can be divided into many types. For example, foldable devices can be specifically mobile phones, tablet computers, laptop computers, e-books, etc.

[0061] like Figure 1 As shown, for the convenience of description, in this application, the support component 012 and the flexible screen 011 (such as an OLED flexible screen) are collectively referred to as the flexible screen component 01, that is, the flexible screen component 01 includes the flexible screen 011 and the support component 012. The flexible screen 011 has a display surface 0111 and a back surface 0112 that is opposite to the display surface 0111. The support component 012 is arranged on the back surface 0112 of the flexible screen 011 to effectively support the flexible screen 011. In addition, the support component 012 also has good flexibility, thereby ensuring the bendability of the flexible screen component 01.

[0062] like Figure 2 As shown, taking mobile phone 02 as an example, mobile phone 02 may include a first shell 021 and a second shell 022 connected by a hinge 023. Under the connection of the hinge 023, relative rotation, movement and other actions can be generated between the first shell 021 and the second shell 022, thereby realizing a foldable function.

[0063] like Figure 2 As shown, when the mobile phone 02 is in a flattened state, the flexible screen 011 can provide a larger display area and operation area to improve usage performance.

[0064] like Figure 3 As shown, when the mobile phone 02 is in a folded state, the flexible screen 011 can be located on the inner side of the mobile phone 02, thereby reducing the area of ​​the mobile phone 02 to improve the portability of the mobile phone 02. Of course, in some examples, when the mobile phone 02 is folded, the flexible screen 011 can also be located on the outer side of the mobile phone 02. That is, the mobile phone 02 can be a mobile phone with an outer folding function or a mobile phone with an inner folding function. In order to facilitate the understanding of the technical solution of the present application, the following will take a mobile phone with an inner folding function as an example for exemplary description.

[0065] like Figure 1 and Figure 2 As shown, when the mobile phone 02 is in a flattened state, the flexible screen 011 is also flattened, thereby providing a larger display area and touch area. In actual use, the flexible screen 011 will be touched or pressed by human hands. The support component 012 is located on the back side 0112 of the flexible screen 011, and can provide effective planar support for the flexible screen 011 to prevent the flexible screen 011 from being pressed to produce deformation or cracks and other undesirable conditions. In addition, when the mobile phone 02 is folded, the support component 012 can also provide effective support for the bending area 0110 of the flexible screen 011 or control the bending deformation of the bending area 0110, thereby improving the reliability and safety of the flexible screen 011.

[0066] Alternatively, the flexible screen assembly 01 can also be used in a rollable device.

[0067] For example, Figure 4 and Figure 5 As shown, the rollable device 03 is specifically an electronic device that can change its own shape by rolling, etc. Under different usage requirements, the user can roll up or unfold the rollable device 03 to meet the different needs of the user.

[0068] like Figure 4 As shown, when the user is using the rollable device 03, the device can be unfolded so that the flexible screen assembly 01 can provide a larger display area and operation area, thereby improving the convenience of use.

[0069] like Figure 5 As shown, when the user needs to carry the rollable device 03 with him, the flexible screen assembly 01 can be rolled up to reduce its volume, thereby improving portability.

[0070] In practical applications, the types of the rollable device 03 can be classified into various types. For example, the rollable device 03 can specifically be a mobile phone, a tablet computer, a notebook computer, an e-book, and the like.

[0071] However, in some current flexible screen assemblies 01, the support assembly 012 has the disadvantages of complex structure and inconvenient manufacturing. Moreover, some support assemblies 012 also have the problem of poor use effect and cannot provide effective support and protection for the flexible screen 011.

[0072] To this end, an embodiment of the present application provides a support component with a simple structure, good support and deformability.

[0073] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] like Figure 6 As shown, in an example provided in the present application, the flexible screen 11 includes a display surface 111 and a back surface 112 opposite to the display surface 111. The support assembly includes a first plate body 121, and the first plate body 121 is arranged on the back surface 112. Among them, the first plate body 121 includes a plurality of curved plates 1211, and each curved plate 1211 extends along a first direction. A plurality of curved plates 1211 are arranged in sequence along a second direction. The first direction and the second direction are both parallel to the back surface, and the first direction is perpendicular to the second direction. The concave side of each curved plate 1211 is away from the back surface 112 of the flexible screen 11.

[0075] In the example provided in the present application, the first plate body 121 includes a plurality of arc-shaped plates 1211, so that the first plate body 121 has good pressure resistance and can effectively support the flexible screen 11, thereby ensuring the flatness of the flexible screen 11. When the display surface 111 of the flexible screen 11 is subjected to a pressing force, the pressing force is transmitted to the first plate body 121. The arc-shaped plate 1211 has good pressure resistance and can effectively support the flexible screen 11, preventing the flexible screen 11 from being dented or other undesirable conditions.

[0076] In addition, the first plate body 121 also has good self-supporting ability and good bendability, and therefore can ensure the flatness and bendability of the flexible screen assembly 10.

[0077] For ease of understanding, a comparative analysis will first be performed below between the conventional flat panel 011 and the first plate body 121 provided in the embodiment of the present application.

[0078] like Figure 7 As shown, it is assumed that one end of the plate 001 (such as Figure 7 The right end of the support assembly 12 (in the figure) is fixed to the vertical wall A, that is, the flat plate 001 is suspended horizontally. The cross-sectional shape of the flat plate 001 is a straight line, and the flat plate 001 is easily bent under the action of gravity G. Therefore, when the support assembly 12 uses the flat plate 001 to support the flexible screen 11, it is difficult to ensure the flatness of the flexible screen 11.

[0079] like Figure 8 As shown, it is assumed that one end of the first plate 121 (such as Figure 8 The first plate 121 is fixed to the vertical wall A, that is, the first plate 121 is suspended horizontally. The cross-sectional shape of the first plate 121 is a curve. Under the action of gravity G, the first plate 121 is not easily bent and has good self-supporting ability. Therefore, when the first plate 121 is used to support the flexible screen 11, the flatness of the flexible screen 11 can be effectively guaranteed.

[0080] It should be noted that, in actual application, the arc plate 1211 in the first plate body 121 is an elastic plate, that is, the arc plate 1211 has elasticity, can bend after being subjected to force, and can return to its original state after the force disappears. The arc plate 1211 can be made of metal materials such as steel, manganese or titanium, or can be made of materials with good elasticity such as metal-based composite materials, plastics or plastic-based composite materials, so that the first plate body 121 has good elasticity. In actual application, the material of the first plate body 121 can be reasonably selected according to actual needs, and will not be elaborated here.

[0081] In addition, when specifically set, the cross section of the arc plate 1211 can be a circular arc or an elliptical arc. For example, when the cross section of the arc plate 1211 is a circular arc, the radius of the arc plate 1211 can be 1 mm, 2 mm, or 3 mm. It should be noted that when the curvature of the arc plate 1211 is larger, the compressive resistance and self-supporting ability of the arc plate 1211 are stronger, and the arc plate 1211 is less likely to be bent. Therefore, in actual application, the curvature of the arc plate 1211 can be reasonably set according to actual needs.

[0082] In addition, if Figure 8 and Fig. 9As shown in FIG. 1 , based on the structural characteristics of the curved plate 1211, when the curved plate 1211 is subjected to a force in the direction of gravity G, it is difficult to bend. However, when the curved plate 1211 is subjected to a force F in the opposite direction of gravity G, it is easier to bend. Therefore, in some practical applications (such as folding mobile phones or folding tablets), in order to provide sufficient support force for the flexible screen (i.e., not easy to bend), the flexible screen can be placed in a Figure 8 The upper surface of the support plate shown in FIG. 1 is the same as the upper surface of the support plate shown in FIG. 1 . At the same time, the direction of the force when bending is consistent with the direction G in the figure. Of course, in other applications, the flexible screen can also be attached to Figure 8 Below the support plate shown, at this time, the bending direction of the flexible screen assembly 10 can be consistent with the direction B of the inner concave surface of the arc plate 1211, so that the folding device using the flexible screen assembly 10 can be easier to bend.

[0083] It should be noted that the bending of the flexible screen assembly 10 requires the application of a certain force, and not any force can bend it. For example, when the force F acts on the first plate 121 to bend the first plate 121, the curvature of the arc plate 1211 will first be reduced. When the curvature of the arc plate 1211 is zero or approaches zero, the first plate 121 will be bent. Since the flexible screen assembly 10 is not easily bent by any force, it will not cause misoperation due to the application of some very small force in actual use, thereby having better reliability of use. In addition, when the force F disappears, since the arc plate is an elastic plate, the arc plate 1211 can be restored to its original curvature under the elastic force of the arc plate 1211 itself, that is, the entire first plate 121 will be restored to a straight state, which can ensure the flatness of the flexible screen 11.

[0084] When the first plate body 121 is configured, the structure type of the first plate body 121 can be various.

[0085] For example, Fig.10 As shown, in an example provided in the present application, each curved plate 1211 has two side edges 12111 parallel to the first direction. The side edges 12111 of the plurality of curved plates 1211 are all located in the first plane D1, so that the concave side of the first plate body 121 has better planar performance.

[0086] In addition, the apex of the convex side of each arc-shaped plate 1211 is located in the second plane D2, so that the convex side of the first plate body 121 has better planar performance.

[0087] The first plane D1 is parallel to the second plane D2 , and the entire first plate body 121 has good flatness, which is also beneficial to reducing the thickness of the first plate body 121 .

[0088] In actual application, the first plane D1, the second plane D2 and the back of the flexible screen 11 can be parallel, so that the first plate 121 can provide effective planar support for the flexible screen 11 and reduce the thickness of the flexible screen assembly 10.

[0089] In the example provided in the present application, two adjacent arc-shaped plates 1211 are fixedly connected, so that the first plate body 121 has good integrity.

[0090] In specific configuration, each arc plate 1211 may be an independently formed structural member, and two adjacent arc plates 1211 may be fixedly connected by welding or bonding, etc. Alternatively, two adjacent arc plates 1211 may also be fixedly connected by elastic material 123 .

[0091] Alternatively, the first plate body 121 may be an integrally formed structural member. For example, the first plate body 121 may be prepared by stamping, extrusion, or the like.

[0092] In practical applications, the preparation process and molding method of the first plate body 121 can be reasonably selected and adjusted according to actual conditions, and this application does not impose any restrictions on this.

[0093] In addition, in practical applications, the curvature of each curved plate 1211 in the first plate body 121 may be the same.

[0094] For example, Fig.11 As shown, in an example provided in the present application, the first plate body 121 includes five arc plates, namely, arc plate 1211a, arc plate 1211b, arc plate 1211c, arc plate 1211d and arc plate 1211e. In a specific configuration, the curvature of each arc plate may be the same.

[0095] Alternatively, the curvature of the curved plate 1211a may be smaller or larger, and the curvatures of the other curved plates may be the same. The curvatures of each curved plate may be different. In summary, among the multiple curved plates of the first plate body 121, at least two curved plates with different curvatures may be included.

[0096] It should be noted that in the examples provided in this application, an exemplary description is given by taking the first plate body 121 as an example in which five curved plates are included. However, in actual application, the first plate body 121 may also include two curved plates, three curved plates, or more curved plates. In specific settings, the number of curved plates can be reasonably set according to actual needs, and no further details are given here.

[0097] In addition, if Fig.12As shown, for a single curved plate 1211, in a first direction (ie, the extension direction of the curved plate 1211), the curvatures of different regions of the curved plate 1211 may be the same, so that the bending properties of different regions of the curved plate 1211 are consistent.

[0098] Or, if Fig.13 As shown, in another example provided in the present application, in the first direction, the curvatures at both ends of the arc-shaped plate 1211 are larger, and the curvature in the middle area is smaller.

[0099] It should be noted that the larger the curvature of the curved plate 1211, the less likely it is to bend. The smaller the curvature of the curved plate 1211, the easier it is to bend. Therefore, when the curvatures of the two ends of the curved plate 1211 are larger and the curvature of the middle area is smaller, when the curved plate 1211 is bent, the middle area is more likely to be bent. Therefore, by reasonably adjusting the curvature size of different areas, the posture of the curved plate 1211 when being bent can be controlled to meet different usage requirements.

[0100] In summary, along the first direction, the arc plate 1211 may have regions with different curvatures. In practical applications, the curvature differences of different regions may be flexibly set according to actual needs.

[0101] In the above example, the first plate body 121 includes the arc-shaped plate 1211. However, in other examples, the first plate body 121 may also include other types of plates.

[0102] For example, Fig.14 As shown, in an example provided in the present application, the first plate body 121 includes an arc-shaped plate 1211 and a connecting plate 1212. The arc-shaped plate 1211 and the connecting plate 1212 are arranged alternately in sequence along the second direction. Specifically, in the second direction, one end of the connecting plate 1212 can be connected to the side of one of the arc-shaped plates 1211, and the other end of the connecting plate 1212 can be connected to the side of another arc-shaped plate 1211.

[0103] In the example provided in the present application, the connecting plate 1212 is a flat plate, and the multiple connecting plates 1212 are all located in the same plane, thereby effectively improving the flatness of the first plate body 121 .

[0104] In a specific configuration, the arc plate 1211 and the connecting plate 1212 may be independently formed structural members, and the arc plate 1211 and the connecting plate 1212 may be fixedly connected by welding or bonding.

[0105] Alternatively, the first plate body 121 may be an integrally formed structural member. For example, the first plate body 121 may be prepared by stamping, extrusion, or the like.

[0106] In practical applications, the preparation process and molding method of the first plate body 121 can be reasonably selected and adjusted according to actual conditions, and this application does not impose any restrictions on this.

[0107] In addition, in actual applications, the width of each connecting plate 1212 may be the same or different. In specific settings, the width of the connecting plate 1212 may be 1 mm, 2 mm, 3 mm or other values. In actual applications, the specific width of the connecting plate 1212 may be reasonably set according to actual needs.

[0108] In summary, the plurality of connecting plates 1212 include at least two connecting plates 1212 having different widths.

[0109] In addition, for a single connecting plate 1212 , the width dimensions of the connecting plate 1212 along the first direction may be the same.

[0110] Alternatively, along the first direction, the connecting plate 1212 has regions with different widths.

[0111] In addition, in practical applications, the width of the connecting plate 1212 can also be reasonably set according to the specific size of the arc-shaped plate 1211 .

[0112] For example, Fig.15 As shown, in an example provided in the present application, the curvature of the middle area of ​​each curved plate 1211 is small, and the width of the middle area is large. In addition, the width of the middle area of ​​each connecting plate 1212 is small, so that the connecting plate 1212 can achieve a better connection effect on the curved plate 1211.

[0113] In addition, if Fig.16 As shown, in an example provided in the present application, the connecting plate 1212 further has a slit 12121 extending along the second direction. The slit 12121 can effectively reduce the weight of the connecting plate 1212, which is conducive to realizing a lightweight design of the first plate body 121.

[0114] In addition, if Fig.17 As shown, in another example provided in the present application, the connecting plate 1212 further has a slit 12122 extending along the first direction. The slit 12122 can effectively reduce the weight of the connecting plate 1212, which is conducive to realizing a lightweight design of the first plate body 121.

[0115] In addition, the gap 12122 can also provide an effective contraction space. When the first plate body 121 is bent, the curvature of the curved plate 1211 in the bent area will be reduced, and expansion deformation will occur in the second direction, thereby squeezing the connecting plate 1212. By providing the gap 12122, the smoothness of the curved plate 1211 during expansion deformation can be improved, and the connecting plate 1212 can be prevented from bulging due to squeezing, thereby improving the elasticity of the first plate body 121.

[0116] like Fig.18 As shown, when the gap 12122 is set, in the first direction, both ends of the gap 12122 can extend to the edge of the connecting plate 1212. In addition, in order to ensure the integrity of the connecting plate 1212, the gap 12122 can be filled with elastic material 123.

[0117] Or, if Fig.19 As shown, in another example provided in the present application, two slits may be provided in the connecting plate 1212, namely, slit 12123 and slit 12124. One end of slit 12123 may extend to one side of the connecting plate 1212, and one end of slit 12124 may extend to the other side of the connecting plate 1212.

[0118] In specific applications, each connecting plate 1212 may have any of the above-mentioned gaps, and the number of gaps may be one, two, or more. Alternatively, at least one connecting plate 1212 may have a gap. In practical applications, the shape, number, and location of the gaps may be flexibly set according to actual needs, and will not be described in detail here.

[0119] Or, if Fig. 20 As shown, in another example provided in the present application, the connecting plate 1212 may have a plurality of notches 12125 , and in the first direction, the plurality of notches 12125 are arranged in sequence and spaced apart.

[0120] In addition, as shown in FIG20 , in the example provided in the present application, two rows of notches 12125 are provided in the connecting plate 1212. Moreover, in the second direction, the notches 12125 are arranged in a staggered manner.

[0121] By providing the notch 12125, the weight of the connecting plate 1212 can be effectively reduced, which is conducive to realizing the lightweight design of the first plate body 121. In addition, the notch 12125 can also provide an effective shrinkage space. When the first plate body 121 is bent, the curvature of the curved plate 1211 in the bent area will be reduced, and an expansion deformation will be generated in the second direction, thereby squeezing the connecting plate 1212. By providing the notch 12125, the smoothness of the curved plate 1211 during expansion deformation can be improved, and the connecting plate 1212 can be prevented from being squeezed and other undesirable conditions such as bulging, thereby improving the elasticity of the first plate body 121.

[0122] In addition, if Fig.21 and Fig. 22 As shown, in an example provided in the present application, the support assembly 12 further includes a second plate 122. The second plate 122 is disposed on one side of the outer arc surface of the arc plate 1211, and the second plate 122 is in contact with the top surface of the outer arc surface of the arc plate 1211.

[0123] The second plate body 122 can provide a relatively flat surface. When the flexible screen 11 is arranged on a side of the second plate body 122 away from the first plate body 121 , the second plate body 122 can effectively support the flexible screen 11 .

[0124] In specific configuration, the first plate 121 and the second plate 122 may be fixedly connected by welding, bonding, etc. Alternatively, the first plate 121 and the second plate 122 may be non-fixedly connected. For example, the second plate 122 may overlap the outer arc side of the first plate 121 to avoid stress between the first plate 121 and the second plate 122.

[0125] Of course, in some examples, the second plate body 122 may also be disposed on one side of the inner concave surface of the first plate body 121. Alternatively, the second plate body 122 may be disposed on both the inner concave side and the outer convex side of the first plate body 121.

[0126] In addition, if Fig.23 As shown, in an example provided in the present application, the gap between the first plate 121 and the second plate 122 is also filled with an elastic material 123. The elastic material 123 can effectively prevent the first plate 121 and the second plate 122 from collapsing, thereby ensuring the structural stability and reliability of the support assembly 12. In addition, when the support assembly 12 is bent, the elastic material 123 can also produce elastic deformation, which will not hinder the normal bending of the support assembly 12.

[0127] In addition, the elastic material 123 can also provide effective elastic force, thereby effectively improving the deformation recovery ability of the support assembly 12. Alternatively, the arc plate 1211 in the first plate body 121 can be made of a material with less elasticity. By using the elastic material 123, the flexibility of the arc plate 1211 in material selection can be effectively improved.

[0128] The elastic material 123 may be rubber, polyethylene, etc. In practical applications, the specific composition of the elastic material 123 may be reasonably selected and adjusted according to actual needs, and will not be described in detail here.

[0129] In a specific implementation, the second plate 122 may have good flexibility so that it can be bent together with the flexible screen 11. For example, the second plate 122 may be made of metal, metal-based composite material, plastic, plastic-based composite material, glass, ceramic or sapphire. In practical applications, the material of the second plate 122 may be reasonably selected according to actual needs, which will not be described in detail here.

[0130] Alternatively, in some examples, the second plate 122 may be omitted. The elastic material 123 may also be filled on the convex side of the arc plate 1211. The convex side of the arc plate 1211 forms a flat surface, thereby effectively improving the flatness of the first plate 121. That is, the support assembly 12 can provide a relatively flat surface through the elastic material 123.

[0131] Or, if Fig.24 As shown, in an example provided in the present application, the concave side of the arc plate 1211 is also filled with an elastic material 123 , and the elasticity of the arc plate 1211 can be effectively improved by the elastic material 123 .

[0132] When setting the flexible screen assembly 10 , the flexible screen 11 can be located on the convex side of the arc plate 1211 , or on the concave side of the arc plate 1211 .

[0133] For example, Fig.25 As shown, in an example provided in the present application, the flexible screen 11 is located on the convex side of the arc plate 1211, so that the flexible screen assembly 10 has a good outward folding or rolling ability. When the flexible screen assembly 10 is folded or rolled, the support assembly 12 can be located on the inner side of the flexible screen 11.

[0134] Or, if Fig.26 As shown, in an example provided in the present application, the flexible screen 11 is located on the concave side of the curved plate 1211, so that the flexible screen assembly 10 has a good inward folding or inward rolling ability. When the flexible screen assembly 10 is folded or rolled, the flexible screen 11 can be located on the inner side of the support assembly 12.

[0135] In addition, in a specific setting, the flexible screen 11 and the support assembly 12 can be fixedly connected by the elastic material 123 mentioned above. Alternatively, the flexible screen 11 and the support assembly 12 can also be fixedly connected by an additional adhesive layer. Alternatively, the flexible screen 11 and the support assembly 12 can also be non-fixedly connected. That is, the support assembly 12 can be set on the back of the flexible screen 11 to avoid stress between the flexible screen 11 and the support assembly 12.

[0136] In specific applications, the flexible screen assembly 10 can be used in a variety of different types of electronic devices.

[0137] For example, Fig. 27 and Fig.28 As shown, in an example provided in an embodiment of the present application, the electronic device 20 may specifically be a foldable device.

[0138] Specifically, the electronic device 20 may include a first housing 21, a second housing 22 and a hinge 23, wherein the hinge 23 is connected between the first housing 21 and the second housing 22. Under the connection of the hinge 23, the first housing 21 and the second housing 22 may be relatively folded or unfolded around a virtual axis O. The virtual axis O is described to facilitate understanding of the folding direction of the electronic device 20. In practical applications, the virtual axis O may be fixed in space or may change with the change of the folding angle of the electronic device 20, and the present application does not limit this.

[0139] The back of the flexible screen assembly 10 can be attached to the surface of the first shell 21 and the second shell 22. As the first shell 21 and the second shell 22 are relatively folded or unfolded, the flexible screen assembly 10 is also folded or unfolded. That is, the first shell 21, the second shell 22 and the hinge 23 together constitute a bendable mechanism for bending the flexible screen assembly 10.

[0140] In addition, if Fig.29 As shown, based on the structural characteristics of the curved plate 1211, when the flexible screen assembly 10 is bent by a force in the direction of the dotted arrow, the flexible screen assembly 10 is relatively easy to bend. On the contrary, when the flexible screen assembly 10 is bent by a force in the opposite direction of the dotted arrow, the flexible screen assembly 10 is relatively difficult to bend.

[0141] Therefore, in the example provided in the present application, the flexible screen assembly 10 is installed behind the surface of the first housing 21 and the second housing 22. The virtual axis O of the electronic device 20 is parallel to the second direction, and the virtual axis O is located on the concave side of the arc plate 1211. When the electronic device 20 is folded, the arc plate 1211 will bend and deform toward the concave side, so that the electronic device is easier to fold.

[0142] In actual application, the connection relationship between the flexible screen assembly 10 and the first shell 21, the second shell 22 and the hinge 23 can be various.

[0143] For example, the support assembly 12 may be fixedly connected to at least one of the first shell 21 , the second shell 22 and the hinge 23 , or may be fixedly connected to all of the first shell 21 , the second shell 22 and the hinge 23 .

[0144] Alternatively, the flexible screen 11 may be fixedly connected to at least one of the first shell 21 , the second shell 22 and the hinge 23 , or may be fixedly connected to all of the first shell 21 , the second shell 22 and the hinge 23 .

[0145] Among them, the connection relationship between the flexible screen assembly 10 and the first shell 21, the second shell 22 and the hinge 23 can be flexibly set according to actual needs.

[0146] In addition, Fig. 27 and Fig.28 In the example shown in , the support assembly 12 has substantially the same area as the flexible screen 11, and the support assembly 11 covers the back of the flexible screen 11. In other examples, the support assembly 12 may also be provided corresponding to a local area of ​​the flexible screen 11.

[0147] For example, Fig.30 As shown, in an example provided in the present application, the support component 12 is disposed in the bending area 110 of the flexible screen 11. In practical applications, the size and location of the support component 12 can be flexibly adjusted according to actual needs, which will not be elaborated here.

[0148] In addition, if Fig.31 and Fig.32 As shown, the embodiment of the present application also provides a roll-up electronic device 30.

[0149] Specifically, the electronic device 30 includes a winding shaft 31, which can rotate around a virtual axis O. One end of the flexible screen assembly 10 is connected to the winding shaft 31, and when the winding shaft 31 rotates, the flexible screen assembly 10 can be wound around the outer circumference of the winding shaft 31.

[0150] In the example provided in the present application, in order to facilitate the winding of the flexible screen assembly 10, the virtual axis O is parallel to the second direction, and the virtual axis O is located on the concave side of the arc plate 1211. When the flexible screen assembly 10 is wound, the arc plate 1211 will bend and deform toward the concave side. Moreover, after the flexible screen assembly 10 is wound, the concave side of the arc plate 1211 faces the outer circumference of the winding shaft 31.

[0151] In practical applications, the flexible screen assembly 10 can also be used in other types of electronic devices, which will not be elaborated here.

[0153] In this application, "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural.
