These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0059] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0060] Optionally, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Optionally, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which needs to be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0061] It should be understood that in the description of this application, terms such as "inner" and "outer" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0062] Furthermore, optionally, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0065] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0066] In some solutions, the protective components are generally installed in a fixed manner. This means that as the electronic product is in different states, when the flexible screen is bent, it is easy to hit the screen, causing problems such as screen cracking.

[0067] The folding device, protective components, and smart terminal provided in this application can realize the unfolding or folding of the flexible screen through the design of the frame component and the rotating component; through the design of the vertically movable protective component, the protective component can not only be placed on the outer edge of the flexible screen, but also rise when the flexible screen is folded, that is, when the first support plate descends, and when the flexible screen supported by the first support plate bends backward, thereby avoiding collision with the flexible screen and thus preventing damage to the display screen. In other words, it solves the problem of the flexible screen bends backward and collides with the protective component, thus causing screen damage.

[0068] To facilitate understanding, the application scenarios applicable to the embodiments of this application will be described below.

[0069] The folding device provided in this application can be applied to smart terminals, which can be of various forms. For example, the smart terminals described in this application may include smart terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0070] The following description will use a smart terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0071] Based on the structure of the aforementioned smart terminal, various embodiments of this application are proposed.

[0074] like Figures 1 to 8 As shown, this application embodiment provides a folding device 100, including:

[0075] The frame assembly 110 includes a base 112, a middle frame 113, and a first support plate 111. The middle frame 113 supports the flexible screen 220. The middle frame 113 and the first support plate 111 are movably disposed on the base 112. The first support plate 111 is configured to rise or fall relative to the base 112.

[0076] Optionally, the folding device 100 further includes a rotating assembly 120, including a rotating arm 121, which is rotatably configured relative to the base 112 to drive the first support plate 111 to rise or fall relative to the base 112.

[0077] The folding device 100 also includes a protective component 130, which includes a protective member 131. The protective member 131 is movably disposed on the base 112 and located above the first support plate 111. The protective member 131 rises relative to the base 112 as the first support plate 111 descends; or, the protective member 131 descends relative to the base 112 as the first support plate 111 rises.

[0078] Through the above-mentioned design, namely the frame component 110 and the rotating component 120, the flexible screen 220 can be unfolded or folded. Through the design of the vertically movable protective member 131, the protective member 131 can not only block the outer edge of the flexible screen 220, but also rise when the flexible screen 220 is folded, that is, when the first support plate 111 descends, and when the flexible screen 220 supported by the first support plate 111 bends backward, thereby avoiding collision with the flexible screen 220 and thus preventing damage to the display screen. In other words, the problem of the flexible screen 220 hitting the protective member 131 due to bending backward and thus causing screen damage is solved.

[0079] The frame assembly 110 provided in this embodiment supports the flexible screen 220, which can bend under external force. The frame assembly 110 can be unfolded to a flattened state (also called the unfolded state), folded to a closed state (also called the folded state), or in an intermediate state between the flattened and closed states, i.e., a semi-folded state. There are multiple consecutive intermediate states between the flattened and closed states. The flexible screen 220 unfolds and folds along with the frame assembly 110.

[0080] Optionally, the flexible screen 220 can be bonded to the mid-frame 113 using an adhesive layer. Optionally, the flexible screen 220 can be an outward-folding screen or an inward-folding screen; this embodiment of the application does not impose further limitations.

[0081] Of course, for ease of explanation, in this embodiment of the application, the flexible screen 220 supported by the middle frame 113 can be an inward-folding screen, which adopts the form of inward folding during the opening and closing of the middle frame 113.

[0082] In this embodiment, the structural design of frame 113 matches the structure of flexible screen 220, so that when flexible screen 220 switches between flat and closed states, it can avoid bulging, thereby improving the display effect.

[0083] In some examples, the middle frame 113 may be a metal component, and its material may include one or more of copper, iron, aluminum, tin, and lead.

[0084] In other examples, the middle frame 113 may also be made of plastic. During injection molding, molten plastic is injected into a plastic product mold under pressure, and then cooled and solidified to obtain the desired plastic part.

[0085] Of course, the material of the middle frame 113 can be the same or different, and this embodiment does not impose too many restrictions here.

[0086] It is understood that the flexible screen 220 can be an outward-folding screen or an inward-folding screen, and this application embodiment will not impose any further restrictions.

[0087] Of course, for ease of explanation, in this embodiment of the application, the flexible screen 220 carried by the frame component 110 can be an inward-folding screen, which adopts the form of inward folding during the opening and closing of the frame component 110.

[0088] In some embodiments, the flexible screen 220 is used to display images.

[0089] Optionally, the flexible screen 220 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MID) display, a micro organic light-emitting diode (MID) display, a micro organic light-emitting diode (MID) display, or a quantum dot light-emitting diode (QLED) display.

[0090] Understandably, the frame assembly 110 can be unfolded to a flattened state (also known as the unfolded state) or folded to a closed state (also known as the folded state) under the drive of the rotating assembly 120.

[0091] Optionally, such as Figures 1 to 5 As shown, the frame assembly 110 has a folded state. During the process of gradually folding the frame assembly 110 from the unfolded state, the middle frame 113 gradually reduces the angle between itself and the base 112 as the rotating arm 121 rotates, so that the flexible screen 220 can be folded and hidden for easy carrying by the user.

[0092] Optionally, such as Figures 6 to 8 As shown, the frame component 110 has an unfolded state. During the process of gradually unfolding the frame component 110 from the folded state, the middle frame 113 gradually increases the angle between itself and the base 112 as the rotating arm 121 rotates, so as to support the flexible screen 220 after it is flattened. The flexible screen 220 is in a flattened state and can display in full screen, so that the smart terminal 200 has a larger display area to improve the user's viewing experience.

[0093] Optionally, when the rotating arm 121 rotates, it can drive the first support plate 111 to rise or fall relative to the base 112.

[0094] Optionally, the folding device 100 also includes a protective component 130, which includes a protective member 131. The protective member 131 is movably disposed on the base 112 and is located at the edge of the flexible screen 220 and above the first support plate 111. It is mainly used to protect the edge of the flexible screen 220, prevent the edge of the flexible screen 220 from being exposed, so that the smart terminal 200 has a better appearance and can prevent the edge of the flexible screen 220 from being damaged by external problems such as collisions, thereby improving the reliability of the smart terminal 200.

[0095] Optionally, the protective member 131 can move upward or downward relative to the base 112, and the protective member 131 and the first support plate 111 can move in opposite directions.

[0096] Optionally, when the first support plate 111 rises, the protective member 131 falls; when the first support plate 111 falls, the protective member 131 rises to avoid collision with the flexible screen 220, thereby avoiding the risk of damage to the flexible screen 220.

[0097] Optionally, the first support plate 111 rising refers to rising relative to the base 112, that is, the first support plate 111 moves in a direction away from the base 112. The first support plate 111 falling refers to falling relative to the base 112, that is, the first support plate 111 moves in a direction facing the base 112.

[0098] Optionally, the lowering of the protective member 131 refers to its lowering relative to the base 112, that is, the protective member 131 moves in the direction facing the base 112. The raising of the protective member 131 refers to its raising relative to the base 112, that is, the protective member 131 moves in the direction away from the base 112.

[0099] Optionally, such as Figures 1 to 5 As shown, when the folding device 100 is in the closed state, the first support plate 111 descends relative to the base 112.

[0100] It should be noted that when the folding device 100 is in the closed state, the first support plate 111 moves in the direction away from the flexible screen 220 to make way for the flexible screen 220 to extend, so that the bent part of the flexible screen 220 can extend freely after folding, and better protect the bent part of the flexible screen 220.

[0101] Optionally, when the first support plate 111 moves in a direction away from the flexible screen 220, the flexible screen 220 is prone to bending. At this time, the protective member 131 moves in the opposite direction to the first support plate 111, thereby increasing the distance between the protective member 131 and the first support plate 111, that is, increasing the distance between the protective member 131 and the flexible screen 220, thereby reducing the risk of collision and improving the safety of the flexible screen 220.

[0102] Optionally, such as Figures 6 to 8 As shown, when the folding device 100 is in the flattened state, the first support plate 111 rises relative to the base 112.

[0103] It should be noted that the folding device 100 has a flattened state. During the process of gradually unfolding the folding device 100 from the folded state, the first support plate 111 moves toward the direction facing the flexible screen 220 as the rotating arm 121 rotates. That is, the first support plate 111 moves upward to support the flexible screen 220 after it is flattened. The flexible screen 220 is in a flattened state and can display the entire screen, so that the smart terminal 200 has a larger display area to improve the user's viewing experience.

[0104] Optionally, when the first support plate 111 moves along the direction facing the flexible screen 220, the flexible screen 220 is supported. At this time, the protective member 131 moves along the opposite direction to the first support plate 111 to return to the initial position, so as to facilitate upward movement when the folding device 100 is in the folded state.

[0105] Optionally, when the folding device 100 is in the flattened state, there is a first gap between the protective member 131 and the first support plate 111; when the folding device 100 is in the closed state, there is a second gap between the protective member 131 and the first support plate 111.

[0106] Optionally, the second gap is larger than the first gap. It should be noted that when the folding device 100 is in the closed state, the second gap is larger than the first gap. This design can effectively prevent the flexible screen 220 from colliding with the protective component 131 when it is bent, thereby reducing the risk of physical damage and extending the service life of the display screen.

[0107] Optionally, users do not need to worry about damage to the display screen due to improper operation when using the folding device 100, which increases user confidence and satisfaction with the product.

[0108] Optionally, by controlling the size of the gap, the device can reduce friction and wear between the protective component 131 and the flexible screen 220 under different conditions, further protecting the surface quality and functional integrity of the flexible screen 220.

[0109] Figure 9 This is an explosion diagram of the protective components of the folding device in its flattened state, as shown in the embodiments of this application. Figure 10 This is a schematic diagram of the assembly of the base and protective components in the unfolded state of the folding device in this embodiment of the application. Figure 11 This is an exploded view of the assembly of the base and protective components in the unfolded state of the folding device in the embodiments of this application.

[0110] like Figures 1 to 11 As shown, optionally, the protective assembly 130 further includes a rotating member 132, which is rotatably mounted on the base 112. The rotating member 132 includes a first end 1321, a second end 1322, and a rotating shaft 1323. The first end 1321 is located below the first support plate 111, and the second end 1322 abuts against the lower side of the protective member 131. Figure 3 As shown, when the first support plate 111 descends, the first support plate 111 provides downward pressure to the first end 1321 to cause the first end 1321 to descend; when the first end 1321 descends, the second end 1322 rotates about the pivot 1323 and provides upward thrust to the protective member 131 to cause the protective member 131 to rise.

[0111] It should be noted that, as Figure 3 As shown, when the first support plate 111 descends, the downward pressure on the first end 1321 is converted into an upward thrust on the protective member 131 by the design of the rotating member 132. This automatic adjustment mechanism can automatically adjust the position of the protective member 131 when the device is folded or unfolded, without the need for an additional drive device or a complex control system.

[0112] With this design, when the first support plate 111 descends, the protective component 131 automatically rises, potentially further increasing the gap between the protective component 131 and the flexible screen 220, thus providing additional protection against squeezing or impact during folding. Users can experience a smoother folding and unfolding process when operating the device, reducing the inconvenience caused by manually adjusting the position of the protective component 131.

[0113] In some embodiments, the rotating shaft 1323 is rotatably disposed on the base 112, wherein the first end 1321 and the second end 1322 are respectively located at the two ends of the rotating shaft 1323.

[0114] Optionally, when the folding device 100 is in the closed state, the first support plate 111 descends to make room for the flexible screen 220 to extend, allowing the bent portion of the flexible screen 220 to extend freely after folding. When the first support plate 111 moves downward, it provides downward pressure to the first end 1321. That is, the first support plate 111 moves downward first, gradually approaching the first end 1321, until it presses against the first end 1321 and pushes the first end 1321 downward. When the first end 1321 moves downward, the second end 1322, located on the other side of the pivot 1323, moves upward, thereby pushing the protective member 131 upward, causing the protective member 131 to move upward.

[0115] Optionally, the rotating component 132 is a bent component. It should be noted that bent components typically offer greater design flexibility, allowing for adjustments to their shape and angle to accommodate different design requirements. This enables the device to better adapt to complex motion paths or spatial constraints.

[0116] Bending components can be manufactured using a simple bending process, which is less expensive and more efficient than complex casting or machining processes. With proper bending design, bending components can increase strength and rigidity in critical areas, thereby improving the durability and lifespan of the components.

[0117] like Figures 3 to 5 ,as well as Figures 7 to 9 As shown, optionally, the protective assembly 130 also includes a fixing plate 133 and an elastic member 134. The fixing plate 133 is disposed on the base 112, and the elastic member 134 is located between the fixing plate 133 and the protective member 131. The elastic member 134 is configured to be in a compressed state when the first support plate 111 is lowered; or, when the first support plate 111 is raised, the elastic member 134 applies an elastic force to the protective member 131 to lower the protective member 131.

[0118] Optionally, the elastic element 134 is in a compressed state when the first support plate 111 descends, providing cushioning and shock absorption. When the first support plate 111 rises, the elastic element 134, in its previous compressed state, can apply an elastic force to the protective element 131, causing the protective element 131 to descend. This achieves the automatic reset function of the protective element 131, ensuring that the protective element 131 can quickly return to its initial position when the device is deployed, providing continuous protection.

[0119] It should be noted that by setting a fixing plate 133 on the protective component 131 and placing an elastic element 134 therebetween, the structural stability of the protective component 130 is increased, preventing the protective component 131 from shaking or shifting unnecessarily during movement.

[0120] It should be noted that the fixed plate 133 provides a stable support surface, giving the elastic element 134 a fixed reference point during compression and release. This increases the overall stability of the protective assembly 130, ensuring consistent performance during movement.

[0121] Optionally, the fixed plate 133 can prevent the elastic element 134 from accidentally shifting or popping out during movement, thereby improving the safety and reliability of the device.

[0122] In some embodiments, the fixing plate 133 is fixedly disposed on the base 112.

[0123] Optionally, the fixing plate 133 is fixed to the base 112 by welding. Optionally, when the first support plate 111 descends, it provides downward pressure to the first end 1321 of the rotating member 132. When the first end 1321 moves downward, the second end 1322 of the rotating member 132 moves upward, thereby pushing the protective member 131 upward, since the fixing plate 133 remains stationary. Therefore, when the protective member 131 moves upward, it drives the end of the elastic member 134 to move upward, thus compressing the elastic member 134.

[0124] When the first support plate 111 rises, the first support plate 111 moves away from the first end 1321 of the rotating member 132. The elastic member 134 provides elastic force to the protective member 131, causing the protective member 131 to move downward, that is, the protective member 131 descends.

[0125] like Figures 3 to 5 ,as well as Figures 7 to 9 As shown, optionally, the protective assembly 130 also includes a guide post 135, which is disposed on the protective member 131 and is movably disposed relative to the fixed plate 133;

[0126] The guide post 135 has a guide boss, and the elastic element 134 is a compression spring and is sleeved on the guide post 135. The elastic element 134 abuts against the guide boss and the fixing plate 133.

[0127] It should be noted that the guide post 135 provides a stable path for the elastic element 134 between the fixed plate 133 and the guide boss, ensuring that the compression spring remains on a predetermined track during compression and release, preventing lateral bending or displacement of the spring, thereby ensuring smoother and more controllable movement of the protective element 131. Optionally, the arrangement of the guide post 135 enhances the structural stability of the entire protective assembly 130, reducing possible swaying or offset during movement.

[0128] In some embodiments, the guide boss and the guide post 135 are integrally formed.

[0129] In some embodiments, the guide post 135 has a cylindrical structure. The elastic member 134 is sleeved on the outer periphery of the guide post 135 and abuts against the guide boss of the guide post 135.

[0130] By abutting the elastic element 134 between the fixed plate 133 and the guide boss, the force transmission path is more direct and efficient. This helps to ensure that the elastic element 134 maximizes its efficiency when applying and releasing forces, providing more reliable motion control for the protective element 131.

[0131] like Figures 3 to 5 ,as well as Figures 7 to 9As shown, optionally, the protective assembly 130 also includes a baffle 136, which is disposed on the protective member 131 and located above the fixing plate 133; the fixing plate 133 has a first opening 1331, and the baffle 136 has a protrusion 1361, which passes through the first opening 1331 and protrudes against the second end 1322.

[0132] It should be noted that by providing a first opening 1331 on the fixed plate 133, the protrusion 1361 can move precisely in the first opening 1331, ensuring that the movement path of the protective assembly 130 is controllable and precise, and reducing unnecessary offset or shaking.

[0133] The protrusion 1361 passes through the first opening 1331 and abuts against the second end 1322, making the connection between the baffle 136 and the protective member 131 more stable.

[0134] Optionally, the fixing plate 133 has a second opening 1332, the guide post 135 passes through the second opening 1332, and moves relative to the fixing plate 133 in the thickness direction of the fixing plate 133.

[0135] It should be noted that by providing a second opening 1332 on the fixed plate 133, the guide post 135 can move precisely in the second opening 1332, ensuring that the movement path of the protective assembly 130 is controllable and precise, and reducing unnecessary offset or shaking.

[0136] The guide post 135 passes through the second opening 1332 and moves in the thickness direction of the fixing plate 133, providing additional support and stability.

[0137] It should be noted that, as Figure 3 As shown, when the folding device 100 is in the closed state, the first support plate 111 descends, the first end 1321 of the rotating member 132 moves downward, and the second end 1322 of the rotating member 132 moves upward. At this time, the second end 1322 of the rotating member 132 pushes the protrusion 1361 to move upward through the first opening 1331, and at the same time, the guide post 135 moves upward and passes through the second opening 1332, wherein at least a portion of the guide post 135 is exposed above the fixed plate 133.

[0138] In some embodiments, the baffle 136 is a bent plate, wherein the bent plate includes the baffle 136 and a mounting plate, the baffle 136 and the mounting plate having an angle between their extending directions, and the mounting plate being used for mounting to the protective member 131.

[0139] Optionally, such as Figure 5 as well as Figure 11 As shown, the base 112 has a cavity 1121 for accommodating the protective component 131.

[0140] It should be noted that the cavity 1121 provides a safe installation position, and the protective component 131 can move up or down within the cavity 1121.

[0141] Optionally, such as Figure 5 as well as Figure 11 As shown, the base 112 has a mounting base 1122, and the rotating member 132 is rotatably mounted on the mounting base 1122.

[0142] It should be noted that the mounting base 1122 provides a stable support point for the rotating component 132, ensuring that the rotating component 132 remains stable and reliable during movement.

[0143] By rotatably mounting the rotating component 132 on the mounting base 1122, precise control of the movement of the rotating component 132 can be achieved, ensuring that it moves within a predetermined path and angle, thereby improving the functionality and reliability of the device.

[0144] Mounting base 1122 provides a dedicated rotating shaft 1323 bearing or support structure for rotating component 132, reducing direct contact between rotating component 132 and other components, thereby reducing wear and friction and extending the service life of the component.

[0145] Optionally, there are at least two middle frames 113, with at least two middle frames 113 located on opposite sides of the base 112.

[0146] Optionally, the frame assembly 110 also includes a second support plate disposed on the middle frame 113 to support the flexible screen 220.

[0147] It is understandable that the two second support plates can rotate relative to the first support plate 111, forming an angle with the first support plate 111, or be parallel to the first support plate 111.

[0148] Optionally, the second support plate is used to support the flexible screen 220. Optionally, when the two second support plates on both sides are in a flattened state with the first support plate 111, the included angle between them can be approximately 180° (a slight deviation is also allowed, such as 166°, 178°, or 184°). The two second support plates on both sides can be rotated relative to each other (unfolded or folded) to an intermediate state so that the smart terminal 200 is in an intermediate state. The two second support plates on both sides can be folded relative to each other to a closed state so that the smart terminal 200 is in a closed state.

[0149] Optionally, the frame component 110 can be in any state between a flattened state and a closed state. Therefore, the smart terminal 200 can switch between the flattened state and the closed state by deforming the frame component 110.

[0150] Optionally, when the two second support plates on both sides are in a flattened state, the second support plates are basically flush with the first support plate 111. At this time, the flexible screen 220 is in a flattened state and can display the entire screen, giving the smart terminal 200 a larger display area to improve the user's viewing experience.

[0151] When the two second support plates on both sides are in the middle position, the flexible screen 220 is in an intermediate state between a flattened and a closed state. When the two second support plates on both sides are in the closed state, the flexible screen 220 is in the closed state, and part of the flexible screen 220 can be folded and hidden for easy carrying by the user.

[0152] The folding device provided in this application includes a frame assembly, including a base, a middle frame, and a first support plate. The middle frame supports a flexible screen. The middle frame and the first support plate are movably disposed on the base. The first support plate is configured to rise or fall relative to the base. A protective assembly includes a protective member, which is movably disposed on the base and located above the first support plate. The protective member rises relative to the base as the first support plate falls, or the protective member falls relative to the base as the first support plate rises.

[0153] The design of the frame and rotating components enables the flexible screen to be unfolded or folded. The design of the vertically movable protective component not only blocks the outer edge of the flexible screen, but also allows the protective component to rise when the flexible screen is folded, i.e., when the first support plate descends. When the flexible screen supported by the first support plate bends backward, the protective component can rise, thereby avoiding collision with the flexible screen and thus preventing damage to the display. In other words, it solves the problem of the flexible screen hitting the protective component due to bending backward, which leads to screen damage.

[0154] Second Embodiment

[0155] The protective component 130 provided in this application embodiment is used in the folding device 100 described above. The protective component 130 includes:

[0156] Rotating component 132 is rotatably disposed on folding device 100. Rotating component 132 has a rotating end and an abutting end, and the abutting end is connected to the rotating end.

[0157] The protective component 131 abuts against the abutting end. When the rotating end rotates, the abutting end provides a pushing force to the protective component 131 so that the protective component 131 rises or falls.

[0158] It should be noted that the rotating end here is the rotating shaft 1323 mentioned above, and the abutting end here is the second end 1322 mentioned above.

[0159] Optionally, the protective assembly 130 also includes a fixing plate 133, which is disposed on the base 112 of the folding device 100.

[0160] Optionally, the protective assembly 130 also includes an elastic element 134 located between the fixed plate 133 and the protective element 131. When the rotating end rotates, the protective element 131 rises to compress the elastic element 134; or, when the rotating end rotates, the elastic element 134 provides elastic force to the protective element 131 to lower the protective element 131.

[0161] Optionally, the protective assembly 130 also includes a guide post 135, which is movably disposed relative to the fixed plate 133, and an elastic element 134 is sleeved on the guide post 135.

[0162] Optionally, the protective assembly 130 also includes a baffle 136, which is disposed on the protective member 131 and located above the fixing plate 133, with the abutting end abutting against the baffle 136.

[0163] The protective component provided in this application includes a rotating member rotatably disposed on a folding device. The rotating member has a rotating end and an abutting end, and the abutting end is connected to the rotating end. A protective member abuts against the abutting end. When the rotating end rotates, the abutting end provides a pushing force to the protective member so that the protective member rises or falls.

[0164] The vertically movable protective components can better match the different states of the flexible screen, solving the problem of the flexible screen being damaged by impact with the protective components due to its recurve.

[0165] Third Embodiment

[0166] The smart terminal provided in this application embodiment includes a flexible screen 220 and the folding device 100 described above.

[0167] It should be noted that the flexible screen 220 can be, but is not limited to, flexible touch screens, flexible touch displays, and other flexible components with corresponding functions.

[0168] It should be noted that the smart terminal 200 provided in this application embodiment can be implemented in various forms. For example, the smart terminal 200 described in this application may include smart terminals such as mobile phones, tablet computers, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0169] In some embodiments, the smart terminal 200 may also include multiple modules (not shown in the figure). The multiple modules of the smart terminal 200 may include, but are not limited to, a motherboard, a processor, a memory, a battery, a camera module, an earpiece module, a speaker module, a microphone module, an antenna module, a sensor module, etc. This application embodiment does not specifically limit the number, type, location, etc. of the modules of the smart terminal.

[0170] The smart terminal provided in this application embodiment can realize the unfolding or folding of the flexible screen through the design of the frame component and the rotating component; through the design of the vertically movable protective component, the protective component can not only be placed on the outer edge of the flexible screen, but also rise when the flexible screen is folded, that is, when the first support plate descends, and when the flexible screen supported by the first support plate bends backward, thereby avoiding collision with the flexible screen and thus preventing damage to the display screen. In other words, it solves the problem of the flexible screen bends backward and collides with the protective component, thus causing screen damage.

[0171] Optionally, the following description will use a smart terminal as an example to illustrate the smart terminal in this application. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0172] Figure 12 This is a schematic diagram of the hardware structure of a smart terminal implementing various embodiments of this application. Please refer to [link / reference]. Figure 12 The smart terminal 200 may include: an RF (Radio Frequency) unit 201, a WiFi module 202, an audio output unit 203, an A / V (Audio / Video) input unit 204, a sensor 205, a display unit 206, a user input unit 207, an interface unit 208, a memory 209, a processor 210, and a power supply 211, etc. Those skilled in the art will understand that... Figure 12 The smart terminal structure shown does not constitute a limitation on the smart terminal. A smart terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0173] The following is combined Figure 12 A detailed introduction to each component of the smart terminal:

[0174] The radio frequency (RF) unit 201 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 210; additionally, it transmits uplink data to the base station. Typically, the RF unit 201 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer. Furthermore, the RF unit 201 can also communicate wirelessly with networks and other devices. The aforementioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G, etc.

[0175] WiFi is a short-range wireless transmission technology. Smart terminals, through the WiFi module 202, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 12 The WiFi module 202 is shown, but it is understood that it is not a necessary component of a smart terminal and can be omitted as needed without changing the essence of the utility model.

[0176] The audio output unit 203 can convert audio data received by the radio frequency unit 201 or the WiFi module 202, or stored in the memory 209, into audio signals and output them as sound when the smart terminal 200 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 203 can also provide audio output related to specific functions performed by the smart terminal 200 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 203 may include a speaker, a buzzer, etc.

[0177] The A / V input unit 204 is used to receive audio or video signals. The A / V input unit 204 may include a graphics processing unit (GPU) 2041 and a microphone 2042. The GPU 2041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 206. The image frames processed by the GPU 2041 can be stored in the memory 209 (or other storage media) or transmitted via the radio frequency unit 201 or the WiFi module 202. The microphone 2042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 201 in telephone call mode. The microphone 2042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0178] The smart terminal 200 also includes at least one sensor 205, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 2061 according to the ambient light level, and the proximity sensor can turn off the display panel 2061 and / or backlight when the smart terminal 200 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that can also be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0179] The display unit 206 is used to display information input by the user or information provided to the user. The display unit 206 may include a display panel 2061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0180] User input unit 207 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the smart terminal. Optionally, user input unit 207 may include touch panel 2071 and other input devices 2072. Touch panel 2071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 2071), and drive corresponding connection devices according to a pre-set program. Touch panel 2071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 210, and can receive and execute commands sent by processor 210. In addition, touch panel 2071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 2071, the user input unit 207 may also include other input devices 2072. Optionally, other input devices 2072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0181] Optionally, the touch panel 2071 may cover the display panel 2061. When the touch panel 2071 detects a touch operation on or near it, it transmits the information to the processor 210 to determine the type of touch event. Subsequently, the processor 210 provides corresponding visual output on the display panel 2061 based on the type of touch event. Although in Figure 12 In this embodiment, the touch panel 2071 and the display panel 2061 are two independent components to realize the input and output functions of the smart terminal. However, in some embodiments, the touch panel 2071 and the display panel 2061 can be integrated to realize the input and output functions of the smart terminal. The specific implementation is not limited here.

[0182] Interface unit 208 serves as an interface through which at least one external device can connect to smart terminal 200. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 208 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within smart terminal 200, or it may be used to transmit data between smart terminal 200 and the external device.

[0183] The memory 209 can be used to store software programs and various data. The memory 209 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 209 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0184] Processor 210 is the control center of the smart terminal. It connects various parts of the smart terminal via various interfaces and lines. By running or executing software programs and / or modules stored in memory 209, and by calling data stored in memory 209, it performs various functions and processes data of the smart terminal, thereby providing overall monitoring of the smart terminal. Processor 210 may include one or more processing units; preferably, processor 210 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 210.

[0185] The smart terminal 200 may also include a power supply 211 (such as a battery) that supplies power to various components. Preferably, the power supply 211 can be logically connected to the processor 210 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0186] although Figure 12 As not shown, the smart terminal 200 may also include a Bluetooth module, etc., which will not be described in detail here.
