Description

Technical Field

[0001] The embodiments of the present application relate to the field of display screens, and in particular to a support assembly and a smart terminal. Background Art

[0002] With the continuous development of display technology, flexible screens are gradually becoming a development trend of future mobile electronic products. Among them, flexible screens can be unfolded and bent. When the flexible screen is unfolded, it can obtain a larger display area and improve the visual effect. When the flexible screen is folded, it can obtain a smaller volume, which is convenient for users to carry.

[0003] However, the bending area of ​​the flexible screen will generate tension during the bending process, causing the flexible screen to arch, thereby reducing the flatness of the flexible screen and affecting the user experience. Summary of the invention

[0004] The embodiments of the present application provide a support assembly and a smart terminal, which solve the problem of arching of the flexible screen.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] According to a first aspect of an embodiment of the present application, a support assembly is provided, the support assembly comprising: a first support component and a second support component; a rotating component arranged between the first support component and the second support component, the first support component being rotatably connected to the second support component through the rotating component; a first sliding component and a second sliding component arranged on both sides of the rotating component, the first sliding component comprising a first plane, the second sliding component comprising a second plane, the first plane and the second plane being used to carry the flexible screen, and the first plane and the second plane being fixedly connected to the flexible screen; when the first support component and / or the second support component rotates around the rotating component so that the angle between the first plane and the second plane decreases, the first sliding component slides relative to the first support component in a direction away from the rotating component; the second sliding component slides relative to the second support component in a direction away from the rotating component; when the first support component and / or the second support component rotates around the rotating component so that the angle between the first plane and the second plane increases, the first sliding component slides relative to the first support component in a direction toward the rotating component; the second sliding component slides relative to the second support component in a direction toward the rotating component.

[0007] The support assembly provided in the embodiment of the present application slidingly connects the flexible screen and the first support component together through a first sliding component, and slidingly connects the flexible screen and the second support component together through a second sliding component, so that when the flexible screen is bent, the first sliding component slides in the plane where the first support component is located, and the second sliding component slides in the plane where the second support component is located, thereby releasing the tension generated by the flexible screen during the bending process and avoiding arching of the flexible screen.

[0008] In an optional implementation, the first supporting component includes a first guiding component, the second supporting component includes a second guiding component, the first sliding component includes a third plane opposite to the first plane, a first sliding block slidably connected to the first guiding component is disposed on the third plane, and the second sliding component includes a fourth plane opposite to the second plane, a second sliding block slidably connected to the second guiding component is disposed on the fourth plane.

[0009] Therefore, sliding can be achieved by cooperating with the slider and the guide component, thereby avoiding the arching of the flexible screen.

[0010] In an optional implementation, the first guide component is a first sliding groove, the second guide component is a second sliding groove, the first slider slides in the first sliding groove in a direction away from or toward the rotating component, and the second slider slides in the second sliding groove in a direction away from or toward the rotating component.

[0011] Therefore, sliding is achieved through the cooperation of the slider and the sliding groove, thereby avoiding the arching of the flexible screen.

[0012] In an optional implementation, a first limiting device is provided on the first slider, and a second limiting device is provided on the second slider, the first limiting device includes a first limiting portion provided at an end of the first slider away from the third plane, the second limiting device includes a second limiting portion provided at an end of the second slider away from the fourth plane, the first sliding groove is located between the third plane and the first limiting portion, and the first limiting portion is used to limit the first slider in a direction toward the third plane; the second sliding groove is located between the fourth plane and the second limiting portion, and the second limiting portion is used to limit the second slider in a direction toward the fourth plane.

[0013] Therefore, by setting a limiter on the slider, when the bending area of ​​the flexible screen bends, the bending area generates outward tension and has a tendency to arch. At this time, the tension is transmitted from the bending area of ​​the flexible screen to the slider, and under the action of the limiter, the slider can only slide within the plane where the first support component and the second support component are located, and cannot move in other directions, thereby further avoiding the arching of the flexible screen.

[0014] In an alternative implementation, the first slider and the first limiting device are detachably connected, and the second slider and the second limiting device are detachably connected.

[0015] Wherein, the first slider is located in the first sliding groove, and the second slider is located in the second sliding groove. Connecting the first slider to the first limiting device and the second slider to the second limiting device in a detachable manner reduces the installation difficulty.

[0016] In an alternative implementation, the first limiting device further includes: a first connecting member connected to the first limiting portion, and the second limiting device further includes: a second connecting member connected to the second limiting portion; the first connecting member is sleeved on the first slider, and the second connecting member is sleeved on the second slider.

[0017] Thus, the first connecting member can be used to support the first limiting portion, so that the first limiting portion is located above the first sliding groove, and the second connecting member can be used to support the second limiting portion, so that the second limiting portion is located above the second sliding groove, which is beneficial for the first limiting portion to limit the first slider.

[0018] Both the first limiting device and the second limiting device are integrally formed into an inverted "T" shape. The inverted "T" shape includes a hollow "|" portion and a "-" portion provided on the "|" portion. The "|" portion of the first limiting device is sleeved outside the first slider, and the "|" portion of the second limiting device is sleeved outside the second slider. The "-" portion of the first limiting device is the first limiting portion, and the "-" portion of the second limiting device is the second limiting portion.

[0019] Thus, the first limiting device and the second limiting device are integrally formed respectively, with higher strength, which is convenient for installation and can protect the first slider and the second slider at the same time.

[0020] In an alternative implementation, the outer side surface of the first slider is provided with an external thread, the inner side surface of the first connecting member is provided with an internal thread, and the first connecting member and the first slider are threadedly connected; the outer side surface of the second slider is provided with an external thread, the inner side surface of the second connecting member is provided with an internal thread, and the second connecting member and the second slider are threadedly connected.

[0021] Thus, the first connecting member and the first slider can be detachably installed together, and the second connecting member and the second slider can be installed together, reducing the installation difficulty.

[0022] In an optional implementation, a third connecting member is provided at one end of the first slider away from the third plane, a fourth connecting member is provided at one end of the second slider away from the fourth plane, the first limiting portion is located between the first slider and the third connecting member, and the second limiting portion is located between the second slider and the fourth connecting member.

[0023] Thus, the first limiting portion can be positioned on the end of the first slider away from the third plane through the third connecting member, and the second limiting portion can be positioned on the end of the second slider away from the fourth plane through the fourth connecting member, thereby reducing the difficulty of installation.

[0024] In an optional implementation, a first limiting portion extending radially is provided at one end of the first slider away from the third plane, and a second limiting portion extending radially is provided at one end of the second slider away from the fourth plane. The first sliding groove is located between the third plane and the first limiting portion, and the first limiting portion is used to limit the first slider in a direction toward the third plane; the second sliding groove is located between the fourth plane and the second limiting portion, and the second limiting portion is used to limit the second slider in a direction toward the fourth plane.

[0025] In an optional implementation, the first guide member and the second guide member are guide rods, the first slider and the second slider are mounted on the guide rods, and when the first support member and / or the second support member rotates around the rotating member, the first slider and the second slider slide along the guide rods.

[0026] Thus, the sliding connection between the slider and the guide rod can achieve sliding, and when the bending area of ​​the flexible screen is bent or unfolded, the bending area generates outward tension, which tends to arch. At this time, the tension is transmitted from the bending area of ​​the flexible screen to the non-bending area, and then passes through the non-bending area in turn to the slider. Under the action of the guide rod, the slider can only slide within the plane where the first support component and the second support component are located, and cannot move in other directions, thereby further preventing the flexible screen from arching during the bending process.

[0027] In an optional implementation, the first slider is bonded to the third plane via an adhesive layer, and the second slider is bonded to the fourth plane via an adhesive layer.

[0028] In an optional implementation, the first slider is welded on the third plane, and the second slider is welded on the fourth plane.

[0029] In an optional implementation, the rotating component includes a rotating shaft, and the first supporting component and the second supporting component are rotatably connected to the rotating shaft.

[0030] The structure of the rotating component described above is only one implementation of the present application, and the present application does not impose any limitation on this.

[0031] In an optional implementation, the rotating portion further includes a bending support member, which is located on a side of the rotating shaft facing the flexible screen and is connected to the rotating shaft, the first supporting component, and the second supporting component.

[0032] Among them, the bending support member includes a flexible connecting layer, and a plurality of rigid support strips spaced apart and arranged along the axial direction of the rotating shaft; the rigid support strips are connected to the flexible connecting layer; the flexible connecting layer is connected to the bending area of ​​the flexible screen through an adhesive layer; the flexible support strips are cross-arranged and connected to the plurality of rigid support strips, and are connected to the bending area of ​​the flexible screen through an adhesive layer; the adhesion between the flexible support strips and the adhesive layer is greater than the adhesion between the flexible connecting layer and the adhesive layer.

[0033] Thus, the flexible support strip can enhance the connectivity between the bending area of ​​the flexible screen and the bending support, making the connection between the flexible screen and the bending support more secure. In addition, the bending support is also connected to the shaft. Therefore, the bending area of ​​the flexible screen can be firmly connected to the support assembly, thereby reducing the probability of debonding of the flexible screen in the bending area and avoiding the phenomenon of arching of the flexible screen.

[0034] In a second aspect of the embodiment of the present application, a smart terminal is provided, the smart terminal comprising the support assembly as described above. The first non-bending area of ​​the flexible screen is connected to the first support component in the support assembly; the second non-bending area of ​​the flexible display screen is connected to the second support component in the support assembly; the bending area of ​​the flexible display screen is connected to the rotating component in the support assembly; wherein the bending area is located between the first non-bending area and the second non-bending area.

[0035] The smart terminal provided in this embodiment includes the supporting assembly as described above, which can prevent the flexible screen from arching. BRIEF DESCRIPTION OF THE DRAWINGS

[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 the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0058] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0059] In order to facilitate the understanding of the support assembly provided in the embodiment of the present application, Fig. 20 , an existing support component is introduced as follows: the flexible screen 10 is a multi-layer structure, for example, including: a first electrode layer, a dielectric thin layer, and a second electrode layer, and each layer is bonded together by optical glue (Optically Clear Adhesive, referred to as OCA), wherein the OCA optical glue is elastic. The support component includes: a support component 301 for carrying the flexible screen 10. The flexible screen 10 includes a non-bending area 101 and a bending area 102. The non-bending area 101 of the flexible screen 10 is fixed on the support component 301. When bending, the tension in the bending area 101 is relatively large. Due to the accumulation of material tension in each layer, a huge tension opposite to the bending direction of the flexible screen is generated, which will cause the flexible screen to arch, thereby reducing the flatness of the flexible screen and affecting the user experience.

[0060] Therefore, an embodiment of the present application provides an improved support assembly to overcome the defect of the flexible screen being arched.

[0061] Figure 1 A three-dimensional schematic diagram of a support assembly provided in an embodiment of the present application. Figure 1 As shown, the support assembly 4 includes: a sliding component 2 fixedly connected to the flexible screen 1 under the flexible screen 1, and a support component 3 slidably connected to the sliding component 2. The flexible screen 1 is, for example, a three-layer composite structure.

[0062] Figure 2 The following is a diagram showing the use status of the support assembly provided in the embodiment of the present application. Figure 2 As shown, the flexible screen can be bent and flattened, wherein the flexible screen is flattened from 180° to a folded state of 0°, or folded from 0° to a flattened state of 180°.

[0063] Figure 3 An exploded view of a support assembly provided in an embodiment of the present application. Figure 4 for Figure 1 YY section view of the middle support assembly.

[0064] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the support component 3 includes: a first support component 31, a second support component 32, and a rotating component 33 located between the first support component 31 and the second support component 32, and the first support component 31 is rotatably connected to the second support component 32 through the rotating component 33. The rotating component 33 can be, for example, a rotating shaft, and the first support component 31 and the second support component 32 can rotate around the axis of the rotating shaft respectively. The rotating component 33 can also be, for example, an elastic component, and the first support component 31 and the second support component 32 are respectively connected to both ends of the elastic component. When the first support component 31 and the second support component 32 generate relative motion, the elastic component can bend or unfold accordingly.

[0065] For example, sliding parts 2 are also provided on both sides of the rotating part 33, and the sliding parts 2 include: a first sliding part 21 and a second sliding part 22, the first sliding part 21 includes a first plane (the top surface of the first sliding part 21), the second sliding part 22 includes a second plane (the top surface of the second sliding part 22), the first plane and the second plane are used to support the flexible screen 1, and the first plane and the second plane are fixedly connected to the flexible screen 1.

[0066] On this basis, if Figure 4 As shown, a portion of the flexible screen 1 is fixed on the first plane through an adhesive layer, a portion is fixed on the second plane through an adhesive layer, and the rest of the flexible screen 1 is located between the first plane and the second plane.

[0067] Among them, the first plane and the second plane are used to support the flexible screen 1, ensure the flatness of the flexible screen 1, and protect the flexible screen 1.

[0068] Among them, the area on the flexible screen 1 connected to the first plane through the adhesive layer is supported by the first plane, and this part of the area is as follows Figure 4 The first non-bending zone 11 is shown.

[0069] Among them, the area on the flexible screen 1 connected to the second plane through the adhesive layer is supported by the second plane, and this part of the area is as follows Figure 4 The second non-bending region 12 is shown.

[0070] In addition, in the flexible screen 1, the portion located between the first non-bending area 11 and the second non-bending area 12 is a bending area 13 that can be bent.

[0071] On this basis, the first non-bending area 11 of the flexible screen 1 can be slidably connected to the first supporting part 31 through the first sliding part 21, and the second non-bending area 12 of the flexible screen 1 and the second sliding part 22 can be slidably connected to the second supporting part (for specific connection methods, please refer to the detailed description below), so that when the flexible screen 1 is layered and displaced, the first sliding part slides within the plane where the first supporting part is located, and the second sliding part slides within the plane where the second supporting part is located, thereby releasing part of the tension of the flexible screen.

[0072] Figure 5 A diagram showing the bending state of the support assembly provided in an embodiment of the present application. Figure 6 This is a diagram of the folded state of the support assembly provided in the embodiment of the present application. Figure 5 As shown, the arrow direction is the tension direction of the flexible screen during the bending process. When the angle α between the first support member 31 and the second support member 32 is less than 180°, the flexible screen 10 is in a bent state.

[0073] Or, if Figure 6 As shown, the arrow direction is the tension direction of the flexible screen during the bending process. When the angle α between the first support member 31 and the second support member 32 is reduced to 0°, the flexible screen 1 is in a folded state.

[0074] When the first supporting component 31 and / or the second supporting component 32 rotates around the rotating component 33, so that the angle between the first plane and the second plane decreases, the flexible screen bends accordingly, and at the same time, the bending area of ​​the flexible screen generates outward tension, which is transmitted from the bending area 13 of the flexible screen to the first sliding component 21 and the second sliding component 22, respectively. The first sliding component 21 slides relative to the first supporting component 31 in a direction away from the rotating component 33, and the second sliding component 22 slides relative to the second supporting component 32 in a direction away from the rotating component 33, thereby realizing that the flexible screen 1 slides with the layered displacement during the bending process, releasing the tension generated during the bending process, and avoiding the flexible screen from arching. Figure 6 The three-layer structure of the flexible screen has layer dislocation.

[0075] The support assembly provided in the embodiment of the present application slidingly connects the flexible screen and the first support component together through a first sliding component, and slidingly connects the flexible screen and the second support component together through a second sliding component, so that when the flexible screen is bent, the tension generated in the bending area of ​​the flexible screen is transmitted to the first sliding component and the second sliding component, which can drive the first sliding component and the second sliding component to slide within the plane where the first support component and / or the second support component are located, so that the flexible screen can slide with the layered displacement, releasing the tension generated during the bending process, and avoiding arching of the flexible screen.

[0076] The following describes the connection method between the first sliding component 21 and the first supporting component 31 , and the connection method between the second sliding component 22 and the second supporting component 32 .

[0077] First, if Figure 3 and Figure 4 As shown, when the first supporting member 31 and the second supporting member 32 are specifically arranged, guide members are arranged on the first supporting member 31 and the second supporting member 32 , for example, the first supporting member is provided with a first sliding groove 34 , and the second supporting member 32 is provided with a second sliding groove 35 .

[0078] Next reference Figure 3 and Figure 4 When the first sliding component 21 and the second sliding component 22 are specifically set, the first sliding component 21, for example, also includes a third plane opposite to the first plane (the bottom surface of the first sliding component 21), and a first slider 23 slidably connected to the first guide component is provided on the third plane. The second sliding component includes a fourth plane opposite to the second plane (the bottom surface of the second sliding component 22), and a second slider 24 slidably connected to the second guide component is provided on the fourth plane.

[0079] The first slider 23 can be fixed on the third plane by adhesive bonding or welding, for example, and the second slider 24 can be fixed on the fourth plane by adhesive bonding or welding. The present application does not limit the fixing method of the first slider and the second slider, and those skilled in the art can select a suitable connection method according to the materials of the first slider and the second slider, which all belong to the protection scope of the present application.

[0080] In this way, through the cooperation of the slider and the sliding groove, the sliding of the sliding component relative to the supporting component is achieved, which can release the tension generated during the bending process and avoid the arching of the flexible screen.

[0081] The first sliding block 23 and the second sliding block 24 may be one or more, and the first sliding groove 34 and the second sliding groove 35 may be one or more.

[0082] like Figure 3 As shown, there are three first sliders 23 and three second sliders 24 , three first sliding grooves 34 and three second sliding grooves, the first sliding grooves 34 correspond one-to-one to the first sliders 23 , and the second sliding grooves 35 correspond one-to-one to the second sliders 24 .

[0083] Figure 7 An exploded view of another support assembly provided in an embodiment of the present application.

[0084] like Figure 7As shown, there is one first slider 23 and one second slider 24, one first sliding groove 34 and one second sliding groove. The first sliding groove 34 is disposed through the first support member 31 along a direction parallel to the rotating member 33, and the second sliding groove 35 is disposed through the second support member 32 along a direction parallel to the rotating member 33.

[0085] This application does not limit the number of the first slider, the second slider, the first sliding groove and the second sliding groove. Those skilled in the art can set them according to needs, and these all fall within the protection scope of this application.

[0086] In addition, a limiting device is provided on the slider, for example, and the limiting device can further limit the arching of the flexible screen.

[0087] In another embodiment of this application, a first limiting device is provided on the first slider, and a second limiting device is provided on the second slider. Figure 8 It is a cross-sectional view of another support assembly provided by an embodiment of this application. Fig. 9 For Figure 8 the exploded view of the middle slider and the sliding groove. Fig.10 For Figure 1 the X-X cross-sectional view in Figure 8 , Fig. 9 , Fig.10 As shown, the first slider 23 includes a connecting plate 231 and a protruding portion 232, and the first slider 23 is connected to the third plane through the connecting plate 231.

[0088] Fig. 9 , Fig.10 Taking the first slider 23 as an example for illustration, the specific structure of the second slider 24 can refer to the first slider 23 and will not be elaborated here.

[0089] Referring to Fig. 9 , Fig.10 , a first limiting device 230 is provided on the first slider 23. The first limiting device 230 is an inverted "T" - shaped structure. The inverted "T" - shaped structure includes a vertical - shaped first connecting portion 2301 and a horizontal - shaped limiting portion 2302 provided on the vertical portion. The vertical - shaped first connecting portion 2301 of the first limiting device is a hollow structure and is sleeved outside the protruding portion 232.

[0090] It is easy to understand that although Fig. 9 the limiting portion 2302 in

[0091] extends radially on both sides of the first connecting portion 2301, in some embodiments, the limiting portion 2302 can also extend radially in the entire circumferential direction of the first connecting portion 2301.In addition, for the convenience of installation, the slider and the limit device can be detachably installed together. The following description continues with the first slider 23 as an example.

[0092] In order to fix the limiting device 230 on the first sliding block 23, in one implementation of the present application, the protrusion 232 can be set as a hollow structural member, and an internal thread can be set on its inner wall, and then the third connecting portion 233 can be threadedly connected to the protrusion 232, and the third connecting portion can be, for example, a bolt. The third connecting portion 233 also includes an outer edge, and the limiting portion 2302 of the limiting device 230 is located between the third connecting portion 233 and the first sliding groove 34, so as to realize the detachable connection between the first sliding block and the first limiting device 230.

[0093] In another implementation of the present application, an external thread can be set on the outer wall of the protrusion 232, and an internal thread can be set on the inner wall of the first connecting part 2301. Then, the protrusion 232 is threadedly connected to the first connecting part 2301, so that the limiting part is located at the end of the first slider away from the third plane, thereby realizing a detachable connection between the first slider and the first limiting device 230.

[0094] It is easy to understand that Fig. 9 What is shown is only an example. In some embodiments, it can be simplified to form a limiting portion integrally at the bottom of the slider.

[0095] The limiting principle of the limiting structure is described below.

[0096] When the bending area of ​​the flexible screen bends, the bending area generates outward tension, which tends to bend. At this time, the tension is transmitted from the bending area of ​​the flexible screen to the slider, and the slider, driven by the tension, tends to move upward in the vertical direction and escape from the sliding groove. The upward movement in the vertical direction refers to the movement in the direction of the flexible screen being arched. At this time, the above-mentioned limit part is clamped on the groove edge of the sliding groove, so the slider cannot move in this direction, further preventing the flexible screen from being arched during the bending process.

[0097] Fig.11 A cross-sectional view of another support assembly provided in an embodiment of the present application. Fig.12 for Fig.11 Schematic diagram of the structure of the first slider. Fig.11 , Fig.12As shown, the first slider 23 and the second slider 24 are in a "cross" structure. The top of the "cross" of the first slider 23 is fixed on the third plane, and the outer edge of the "cross" of the first slider 23 is clamped in the depression inside the sliding groove. The top of the "cross" of the second slider 24 is fixed on the fourth plane, and the outer edge of the "cross" of the second slider 24 is clamped in the depression inside the sliding groove. The first slider and the second slider of the "cross" structure can limit the arching of the flexible screen.

[0098] When the bending area of ​​the flexible screen bends, the bending area generates outward tension and tends to arch. At this time, the tension is transmitted from the bending area of ​​the flexible screen to the slider, and the slider tends to move upward in the vertical direction and escape from the sliding groove, wherein the upward movement in the vertical direction refers to the movement in the direction of the flexible screen arching. Under the action of the above-mentioned "cross" shaped outer edge, the slider cannot move in this direction, thereby avoiding the arching of the flexible screen.

[0099] In another embodiment of the present application, the guide component includes the above-mentioned limiting structure. Fig.13 A schematic diagram of another limiting structure provided in an embodiment of the present application. Fig.14 for Fig.13 Schematic diagram of the structure of the first slider. Fig.13 , Fig.14 As shown, the guide component is a guide rod, the first slider 23 is sleeved on the first guide rod 36, the second slider 24 is sleeved on the second guide rod 37, both ends of the first guide rod 36 are connected to the first support component 31, and both ends of the second guide rod 37 are connected to the second support component 32. The guide rod can be used as the above-mentioned limiting structure.

[0100] When the bending area of ​​the flexible screen bends, the bending area generates outward tension and tends to arch. At this time, the tension is transmitted from the bending area of ​​the flexible screen to the slider, and the slider tends to move upward in the vertical direction and escape from the sliding groove, wherein the upward movement in the vertical direction refers to the movement in the direction of the flexible screen arching. However, under the action of the above-mentioned guide rod, the slider can only slide within the plane where the first support component 31 and the second support component 32 are located, and cannot move in other directions, thereby preventing the flexible screen from arching during the bending process.

[0101] The first sliding block 23 and the second sliding block 24 may be one or more than one sliding block arranged side by side on the third plane, and the first guide rod 36 and the second guide rod 37 may be one or more than one sliding block.

[0102] The above-mentioned limiting the arching of the flexible screen by a limiting structure is only one implementation method of the present application, and the present application does not impose any restrictions on this. Technical personnel in this field can set a suitable limiting structure as needed to limit the movement of the first slider 23 within the plane where the first support component 31 is located, and limit the movement of the second slider 24 within the plane where the second support component 32 is located, which all fall within the protection scope of the present application.

[0103] In addition, when the rotating component 33 is specifically provided, the rotating component may be, for example, a rotating shaft, Fig.15 This is a schematic diagram of the structure of the rotating component provided in the embodiment of the present application. Fig.15 As shown, the rotating shaft is connected to the first supporting component 31 and the second supporting component 32, and the first supporting component 31 and the second supporting component 32 can rotate around the axis of the rotating shaft respectively.

[0104] In order to make the first support member 31 and the second support member 32 rotatably connected through the rotating shaft, the support assembly further includes: Fig.12 A first blade 331 and a second blade 332 are shown.

[0105] One end of the first blade 331 is connected to the rotating shaft, and the other end is connected to the rotating shaft. Fig.15 As shown, it can extend into the installation groove below the first support component 31 and be connected to the first support component 31 through screws installed in the threaded holes 333.

[0106] Similarly, one end of the second blade 332 is connected to the rotating shaft, and the other end can extend into the installation groove below the second supporting component 32 and be connected to the second supporting component 32 through a screw installed in the threaded hole 333.

[0107] Based on this, in some embodiments of the present application, the structure of the above-mentioned rotating shaft can be as follows: Fig.15 As shown, it includes a first rotating shaft 334 and a second rotating shaft 335 which are coaxially arranged. At this time, the axes of the first rotating shaft 334 and the second rotating shaft 335 are as follows: Fig.15 The axis of the rotating shaft is shown.

[0108] The first rotating shaft 334 is connected to the first blade 331 , and the second rotating shaft 335 is connected to the second blade 332 .

[0109] like Fig.15 As shown, the first rotating shaft 334 and the second rotating shaft 335 rotate in opposite directions. The first rotating shaft 334 drives the first supporting component 31 to rotate around the axis of the first rotating shaft 334 through the first blade 331. The second rotating shaft 335 drives the second supporting component 32 to rotate around the axis of the second rotating shaft 335 through the second blade 333.

[0110] Since the axes of the first rotation axis 334 and the second rotation axis 335 can be used as Fig.12 The axis of the rotating shaft is shown, so that the first supporting component 31 and the second supporting component 32 can rotate along the axis of the rotating shaft respectively.

[0111] It should be noted that the above is an example of the shaft structure, and shafts of other structures are not described here one by one. This application does not limit the structure of the above shaft, as long as the first support member 31 and the second support member 32 can be rotatably connected through the shaft.

[0112] On this basis, in order to support the bending zone 13 of the above-mentioned flexible screen 1 to improve the stiffness and impact resistance of the bending zone 13 while ensuring that the bending performance of the bending zone 13 of the flexible screen 1 can meet the requirements, the embodiment of the present application also provides a rotating component. Fig.16 This is a schematic diagram of the structure of another rotating component provided in an embodiment of the present application. Fig.16 As shown, the support assembly further includes a bending support member 30 .

[0113] The bending support member 30 is located on the side of the rotating shaft facing the flexible screen 1. The bending support member 30 is also connected to the first support component 31 and the second support component 32.

[0114] For example, Fig.16 As shown, a first groove 311 is provided on a surface of the first support component 31 facing the flexible screen 1. One end of the bending support member 30 close to the first support component 31 can be bonded in the first groove 311 by an adhesive layer.

[0115] The second support component 32 has a second groove 321 on one side facing the flexible screen 1. One end of the bending support member 30 close to the second support component 32 can be bonded in the second groove 321 by an adhesive layer.

[0116] In addition, the middle area of ​​the bending support member 30 , except for the portion connected to the first support component 31 and the second support component 32 , is connected to the rotation shaft.

[0117] It should be noted that the present application does not limit the manner in which the bending support member 30 is connected to the rotating shaft.

[0118] From the above, it can be seen that, on the one hand, the bending support 30 needs to support the bending area 13 so that during the bending process of the flexible screen 1, the bending area 13 of the flexible screen 1 has good impact resistance, thereby reducing the probability of damage to the flexible screen 1 in the bending area 13.

[0119] On the other hand, the bending support member 30 also needs to have good flexibility to ensure that the maximum bending angle of the bending zone 13 of the flexible screen 1 can meet the requirements.

[0120] In order to meet the above requirements, the present application also provides a rotating component. Fig.17 This is a schematic diagram of the structure of another rotating component provided in an embodiment of the present application. Fig.17 As shown, the bending support member 30 includes a flexible connection layer 301 and a plurality of rigid support bars 302 that are spaced apart and arranged along the axis OO of the shaft.

[0121] The rigidity of the material constituting the rigid support strip 302 is greater than the rigidity of the material constituting the flexible connection layer 301 .

[0122] For example, the material constituting the rigid support bar 302 may be a metal element, such as tungsten or molybdenum; or may be a metal compound, such as aluminum alloy.

[0123] The material constituting the flexible connection layer 301 may be a silicone material with high flexibility. In this way, the flexible material layer 301 can make the bending support member 30 have a certain flexibility, thereby ensuring that the maximum bending angle of the bending area 13 of the flexible screen 1 can reach the requirement.

[0124] In addition, the rigid support bar 302 can provide strong rigidity for the bending support member 30, so that the bending support member 30 has good supporting performance, thereby improving the impact resistance of the bending area 13 of the flexible screen 1 during the bending process of the folding display terminal 01.

[0125] The following is an example of the configuration of the rigid support strip 302 and the flexible connection layer 301 in the bending support member 30.

[0126] For example, in some embodiments of the present application, Fig.17 As shown, a plurality of rigid support bars 302 are located on the surface of the flexible connection layer 301 , the plurality of rigid support bars 302 are arranged at intervals, and each rigid support bar 302 is connected to the flexible connection layer 301 .

[0127] In this way, since the surface of the flexible connecting layer 301 is flat, after it is bonded to the flexible screen 1, the surface flatness of the bending area 13 of the flexible screen 1 can be improved, reducing the probability of the flexible screen 1 being arched due to debonding.

[0128] As can be seen from the above, the material constituting the flexible connection layer 301 can be a silicone material. The silicone material has good flexibility, so that the maximum bending angle of the bending area 13 of the flexible screen 1 can meet the requirements.

[0129] However, when the flexible connecting layer 301 composed of silicone is connected to the bending area 13 of the flexible screen 1 through the glue layer, due to the weak adhesion between the silicone and the glue layer, after the flexible screen 1 is bent multiple times, the bending area 13 of the flexible screen 1 will become debonded, causing the flexible screen 1 to bulge.

[0130] In order to solve the above problems, the present application also provides a rotating component. Fig.18 A schematic diagram of another structure of a rotating component provided in an embodiment of the present application. Fig.18 As shown, at least one flexible support bar 40 is also included. The flexible support bar 40 is cross-arranged and connected with a plurality of rigid support bars 302.

[0131] In some embodiments of the present application, the flexible support bar 40 may be vertically arranged with respect to the plurality of rigid support bars 302 .

[0132] In addition, a surface of the flexible support strip 40 facing the flexible screen 1 is connected to the bending area 13 of the flexible screen 1 through an adhesive layer.

[0133] In this case, the bending area 13 of the flexible screen 1 is not only connected to the flexible connection layer 301 in the bending support member 30 through the adhesive layer, but also connected to the flexible support bar 40 through the adhesive layer. In addition, since the flexible support bar 40 is cross-arranged and connected with the plurality of rigid support bars 302, the flexible support bar 40 can be connected to the entire bending support member 30.

[0134] In this way, the portion of the bending area 13 of the flexible screen 1 that is connected to the flexible support strip 40 is connected to the bending support member 30 through the flexible support strip 40 .

[0135] On this basis, the adhesion between the flexible support strip 40 and the above-mentioned adhesive layer is greater than the adhesion between the flexible connection layer 301 and the adhesive layer. Exemplarily, the material constituting the flexible connection layer 301 is the above-mentioned silicone. The material constituting the flexible support strip 40 can be a bendable plastic material, for example, thermoplastic polyurethanes (TPU), thermoplastic elastomer (TPE) or rubber.

[0136] In this way, the flexible support strip 40 can enhance the connectivity between the bending area 13 of the flexible screen 1 and the bending support member 30, making the connection between the flexible screen 10 and the bending support member 30 more secure. In addition, the bending support member 30 is also connected to the rotating shaft. Therefore, the bending area 13 of the flexible screen 10 can be firmly connected to the support assembly, thereby reducing the probability of debonding of the flexible screen 1 in the bending area 13 and avoiding the phenomenon of arching of the flexible screen 1.

[0137] An embodiment of the present application further provides a smart terminal, which may be a product with a display interface, such as a mobile phone, a display, a tablet computer, or a car computer. Fig.19 A schematic diagram of the structure of the intelligent terminal provided in the embodiment of the present application (the terminal body is not shown), as shown in FIG. Fig.19 As shown, the smart terminal includes the above supporting assembly and also includes a back cover 5. The embodiment of the present application does not impose any special limitation on the specific form of the above smart terminal.

[0138] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
