The drawings and the written description are not intended to restrict the scope of the present application in any way, but are merely illustrative of the concept of the present application as described by the claims. DETAILED DESCRIPTION

[0053] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description is merely illustrative of the concept of the present application and is not intended to restrict the scope of the present application in any way. Rather, it is merely an example of apparatus and methods in accordance with some aspects of the present application, as detailed in the appended claims.

[0054] The present embodiment provides a folding terminal, Figure 1 is an exploded structural schematic view of a folding terminal according to an embodiment, although Figure 1 The folding terminal is not limited to a mobile phone, but can also be a tablet computer, a display, and the like.

[0055] It should be noted that the folding terminal switches between flattening and folding under the action of a folding mechanism. Since the improvement point of the present embodiment is not the folding mechanism, the folding mechanism is not shown in the drawings.

[0056] The folding terminal can be a terminal that can fold left and right, or it can be a terminal that can fold up and down. In this embodiment, there is no limitation on whether the folding terminal folds left and right or up and down. The accompanying drawings can be used as an example of folding left and right.

[0057] The folding terminal can be folded inwards or outwards. An inward fold means that when the terminal is folded, the display screen 2 is located on the inside. An outward fold means that when the terminal is folded, the display screen 2 is located on the outside.

[0058] like Figure 1 As shown, the folding terminal includes a body 1 and a display screen 2, with the display screen 2 laid on the surface of the body 1. The body 1 is a component used to support and fix the display screen 2, and can specifically be a middle frame or a structure including a middle frame.

[0059] In this design, display screen 2 is a flexible display screen. Because it is flexible, its rigidity is relatively weak and it generally requires reinforcement for support. Therefore, display screen 2 can include a reinforcement and a screen, which are bonded together to form display screen 2. The reinforcement can be a steel sheet (SUS). Therefore, the display screen 2 described below can specifically refer to the reinforcement of display screen 2, or it can also be specifically the assembly formed by bonding the reinforcement and the screen.

[0060] In this embodiment, the specific structure of the body 1 and the display screen 2 is not limited. The following will describe the fixing relationship between the body 1, the display screen 2 and the flattening component 3, as well as the scheme for flattening the display screen 2 in the bending area.

[0061] In one example, since the folding terminal is capable of folding, the body 1 may include two or more body sections 11, with two adjacent body sections 11 being rotatably connected. The two adjacent body sections 11 can be rotatably connected under the action of the folding structure.

[0062] For example, the body 1 includes two body sections 11, and the foldable terminal can be folded into a dual-screen configuration. Or, for example, the body 1 includes three body sections 11, and the foldable terminal can be folded into a triple-screen configuration. The body 1 may also include more body sections 11, allowing it to be folded into more screen configurations.

[0063] In this embodiment, the number of fuselage sections 11 included in the fuselage 1 is not limited, and two adjacent fuselage sections 11 can be used as an example.

[0064] To accommodate the folding of the folding terminal, the display screen 2 includes at least one bendable portion 21. The portion of the display screen 2 other than the bendable portion 21 is used to fix it to the body 1 and can be referred to as a fixing portion 22. Therefore, the display screen 2 includes at least one bendable portion 21 and a plurality of fixing portions 22, with each bendable portion 21 located between two adjacent fixing portions 22.

[0065] For example, if the foldable terminal can fold into a dual-screen configuration, the number of bendable parts 21 is one, and the number of fixing parts 22 is two. As another example, if the foldable terminal can fold into a triple-screen configuration, the number of bendable parts 21 is two, and the number of fixing parts 22 is three. If the foldable terminal can fold into even more screens, the number of bendable parts 21 and the number of fixing parts 22 will also increase.

[0066] In this embodiment, the number of bendable portions 21 and the number of fixing portions 22 included in the display screen 2 are not limited. An example can be given by one bendable portion 21 and two fixing portions 22 adjacent to the bendable portion 21.

[0067] For example, such as Figure 2 As shown, the display screen 2 is laid on the surface of the body 1, and the fixed part 22 and the body part 11 are fixedly connected. The bendable part 21 of the display screen 2 and the body part 11 of the body 1 are not fixed, so that they can be stretched and contracted during folding.

[0068] The fixing method between the body part 11 of the body 1 and the fixing part 22 of the display screen 2 can be achieved by adhesive bonding, for example, Figure 2 As shown, there is an adhesive layer 4 between the fuselage 11 and the fixing part 22.

[0069] To prevent the bendable portion 21 of the display screen 2 from deforming at the folding point during repeated folding of the foldable terminal, thus avoiding collapse when it is flattened, accordingly, as Figure 1 As shown, the folding terminal includes a flattening member 3 located between the body 11 and the bendable portion 21. For example, a portion of the flattening member 3 is located between one of the body portions 11 and the bendable portion 21, and another portion of the flattening member 3 is located between the other body portion 11 and the bendable portion 21. The flattening member 3 is configured to apply a force to the bendable portion 21 when the folding terminal is in a flattened state, causing the bendable portion 21 to flatten.

[0070] The unfolded state of the folding terminal can be a state in which the two body parts 11 of the folding terminal are on the same plane, that is, the included angle between the two body parts 11 is 180 degrees. The folded state of the folding terminal can be a state in which the included angle between the two body parts 11 is greater than or equal to 0 degrees and less than 180 degrees. The state in which the included angle between the two body parts 11 is 0 degrees can be called the folded state of the folding terminal, or it can also be called the fully folded state.

[0071] In one example, when the display screen 2 is in a flattened state, the flattening member 3 can apply a pulling force toward the fixed part 22 to the bendable part 21 to flatten the bendable part 21. The flattening member 3 can also apply a force perpendicular to the fixed part 22 and toward the display screen 2 to the bendable part 21 to flatten the bendable part 21.

[0072] In this way, since the folding terminal includes a flattening component 3, when the folding terminal is in the flattened state, the flattening component 3 can apply a force to the bendable portion 21 of the display screen 2 to flatten the bendable portion 21. Therefore, after the folding terminal switches from the folded state to the flattened state, the display screen of the folding terminal can be flattened in the bending area, thereby enhancing the user's visual effect and improving the user experience.

[0073] As described above, the flattening component 3 can apply tensile force to the bendable portion 21 of the display screen 2. Accordingly, the structure of this flattening component 3 can be as follows: Figure 1 As shown, it includes two sets of limiting protrusions 31, each set of limiting protrusions 31 including a first protrusion 311 and a second protrusion 312.

[0074] Among them, such as Figure 1 As shown, each of the first protrusions 311 and the second protrusions 312 is elongated, with the direction of the strip parallel to the center line L of the bendable portion 21. The center line L of the bendable portion 21 can be the crease line of the bendable portion 21.

[0075] like Figure 1 As shown, the first protrusion 311 of the two sets of limiting protrusions 31 is fixed on both sides of the center line L of the bendable part 21. That is, the first protrusion 311 of one set of limiting protrusions 31 is located on one side of the center line L of the bendable part 21, and the first protrusion 311 of the other set of limiting protrusions 31 is located on the opposite side of the center line L of the bendable part 21.

[0076] like Figure 1 As shown, the second protrusion 312 of both sets of limiting protrusions 31 are fixed to the fuselage 1, for example, respectively fixed to two fuselage sections 11. That is, the second protrusion 312 of one set of limiting protrusions 31 is fixed to one fuselage section 11, and the second protrusion 312 of the other set of limiting protrusions 31 is fixed to the other fuselage section 11.

[0077] likeFigure 2 As shown, two second protrusions 312 are located between two first protrusions 311, that is, the first protrusion 311 in each group of limiting protrusions 31 is away from the center line L of the bendable part 21, and the second protrusion 312 is close to the center line L of the bendable part 21. Continue to refer to Figure 2 As shown, when the folding terminal is in the unfolded state, the first protrusion 311 and the second protrusion 312 of each group of limiting protrusions 31 are in close contact.

[0078] Wherein, the first protrusion 311 and the second protrusion 312 are in close contact, that is, the first protrusion 311 and the second protrusion 312 are in contact and there is a force between them, both of which are interference fit.

[0079] In this way, when the folding terminal is switched from the folded state to the unfolded state, referring to Figure 2 As shown, if the bendable part 21 of the display screen 2 collapses or bulges, but due to the interference fit of the first protrusion 311 and the second protrusion 312 in the same group, the second protrusion 312 will apply a pushing force to the first protrusion 311. For example, the second protrusion 312 on the left side of the center line L will apply a left pushing force to the first protrusion 311, and the second protrusion 312 on the right side of the center line L will apply a right pushing force to the first protrusion 311, thereby causing the bendable part 21 to be stretched and unfolded.

[0080] In an example, the height of the first protrusion 311 and the second protrusion 312 in each group of limiting protrusions 31 can be related to the distance between the display screen 2 and the body 1. For example, the height of the first protrusion 311 and the second protrusion 312 can be slightly smaller than the distance between the display screen 2 and the body 1, so that the contact area of the first protrusion 311 and the second protrusion 312 is larger, and the second protrusion 312 is not easy to miss in pushing the first protrusion 311.

[0081] Wherein, the height of the first protrusion 311 and the second protrusion 312 in the embodiment is not limited, and when the folding terminal is in the unfolded state, the second protrusion 312 in the same group can push the first protrusion 311 to make the bendable part 21 unfold.

[0082] In an example, since the distance between the body 1 and the display screen 2 is relatively small, the height of the first protrusion 311 and the second protrusion 312 is also relatively small. If the height of the first protrusion 311 and the second protrusion 312 is too small, the second protrusion 312 will miss the first protrusion 311 in pushing the first protrusion 311, for example, the second protrusion 312 on the left side of the center line L will miss the first protrusion 311 and move to the left side of the first protrusion 311, and the second protrusion 312 on the right side of the center line L will miss the first protrusion 311 and move to the right side of the first protrusion 311.

[0083] In order to avoid the second protrusion 312 from being misaligned in pushing the first protrusion 311 due to the small height of the first protrusion 311 and the second protrusion 312, as shown in Figure 3 the body 1 has a groove 12 at a position opposite to the bendable part 21. Thus, due to the existence of the groove 12, the distance between the bendable part 21 and the body 1 is also increased, and the second protrusion 312 of each set of limiting protrusions 31 is located in the groove 12, so that the height of the first protrusion 311 and the second protrusion 312 can also be increased. Once the height of the first protrusion 311 and the second protrusion 312 is relatively large, the second protrusion 312 can be avoided from being misaligned with the first protrusion 311 in pushing the first protrusion 311.

[0084] In the embodiment, whether the body 1 is provided with the groove 12 at the position corresponding to the bendable part 21 is not limited, and can be flexibly designed according to the actual situation.

[0085] As to the shape of the first protrusion 311 and the second protrusion 312 in each set of limiting protrusions 31, as shown in Figure 1 and referring to Figure 2 the cross-sectional shape of the first protrusion 311 and the second protrusion 312 can be rectangular.

[0086] For example, as shown in Figure 4 and referring to Figure 5 the cross-sectional shape of the first protrusion 311 and the second protrusion 312 can be L-shaped, and the protrusion with this shape can be referred to as an L-shaped protrusion structure.

[0087] Then, as shown in Figure 4 the first protrusion 311 includes a vertical part a and a horizontal part b, and the second protrusion 312 also includes a vertical part a and a horizontal part b.

[0088] As shown in Figure 4 the vertical part a of the two first protrusions 311 is fixed with the bendable part 21, and the horizontal part b of the two first protrusions 311 is close to each other. The vertical part a of the two second protrusions 312 is fixed with the body 1, and the horizontal part b of the two second protrusions 312 is away from each other.

[0089] As shown in Figure 5 when the folding terminal is in the unfolded state, the horizontal part b of each first protrusion 311 is in close contact with the vertical part a of the second protrusion 312 in the same set, and the vertical part a of each first protrusion 311 is in close contact with the horizontal part b of the second protrusion 312 in the same set.

[0090] In the embodiment, the angle between the vertical part a and the horizontal part b of the first protrusion 311 and the second protrusion 312 can be a rounded right angle.

[0091] In the embodiment, the specific shape of the first protrusion 311 and the second protrusion 312 of each set of the limiting protrusions 31 is not limited, and the force applied to the bendable part 21 to make the bendable part 21 flatten can be realized.

[0092] As described above, when the folding terminal is in the flattened state, the flattening part 3 can also make the bendable part 21 flatten by applying a force to the bendable part 21, which is perpendicular to the bendable part 21 and points to the direction of facing away from the body 1. Correspondingly, as shown in Figure 6 , the flattening part 3 can include two elastic parts 32, which are located on both sides of the center line L of the bendable part 21. As shown in Figure 7 , when the folding terminal is in the flattened state, the two elastic parts 32 are in contact and are in close contact with the bendable part 21. When the folding terminal is in the folded state, the two elastic parts 32 are away from each other, which can be referred to Figure 8 , which is a schematic view of the folding terminal in the folded state.

[0093] In the embodiment, the elastic part 32 can have elasticity in the thickness direction and can be compressed in the thickness direction. When the display screen 2 is in the flattened state, the elastic part 32 is compressed between the bendable part 21 and the body 1 to realize the close contact between the elastic part 32 and the bendable part 21.

[0094] In an example, the material of the elastic part 32 can be a silica gel pad or a copper foil or a foam, etc. The silica gel pad or the copper foil has a certain thickness and can be compressed in the thickness direction and can rebound after the external force that compresses it is removed.

[0095] In an example, since the bendable part 21 is prone to collapse or bulge at the crease, for example, the bendable part 21 is prone to collapse or bulge at the center line L, the thickness of the elastic part 32 can gradually decrease from the first end to the second end of the elastic part 32. The first end and the second end of the elastic part 32 are opposite to each other, and the first end is one end located at the center line L of the bendable part 21, which can be referred to Figure 6 and Figure 7 .

[0096] In an example, the shape of the surface of the elastic part 32 can be arc-shaped to realize the gradual decrease of the thickness of the elastic part 32 from the first end to the second end. For example, as shown in Figure 6 , the shape of the surface of the elastic part 32 close to the bendable part 21 is arc-shaped. Alternatively, the surface of the elastic part 32 facing away from the bendable part 21 can also be arc-shaped.

[0097] Of course, the thickness of the elastic part 32 at each position can also be equal, that is, the thickness of the elastic part 32 at each position from the first end to the second end is equal.

[0098] In this embodiment, the thickness distribution of the elastic element 32 is not limited. When the folded end is flattened, the elastic element 32 is compressed near the center line L, and a vertical upward force is applied to the bendable part 21, so that the bendable part 21 can be flattened.

[0099] As described above, two elastic members 32 are located between the fuselage 1 and the bendable portion 21. Regarding the fixing relationship of the elastic members 32, one possibility is that the elastic members 32 can be fixed to the fuselage portion 11 of the fuselage 1, for example... Figure 6 As shown, the elastic member 32 located on the same side of the center line L of the bendable portion 21 is fixed to the body portion 11. The first end of the elastic member 32 near the center line L and the first end of the body portion 11 near the center line L can be flush so that when the folding end is in the flattened state, the two elastic members 32 can contact each other and lift the bendable portion 21 to flatten it.

[0100] In one example, the elastic element 32 can also be fixedly connected to the display screen 2, such as... Figure 9 As shown, the elastic element 32 located on the same side of the center line L of the bendable part 21 is fixedly connected to the display screen 2, and the elastic element 32 and the bendable part 21 are not fixed, so that the elastic element 32 will not affect the bending and folding of the bendable part 21.

[0101] For example, such as Figure 9 As shown, the portion of the elastic member 32 near its second end is fixedly connected to the fixed portion 22, while the portion of the elastic member 32 near its first end is not fixed to the bendable portion 21. The first end of the elastic member 32 is the end near the center line L of the bendable portion 21, and the second end of the elastic member 32 is the end away from the center line L of the bendable portion 21. The positions of the first end and the second end are opposite to each other.

[0102] In this embodiment, there is no limitation on whether the elastic element 32 is fixedly connected to the body part 11 of the body 1 or to the fixing part 22 of the display screen 2, and the choice can be made flexibly according to the actual situation.

[0103] The elastic sheet 32 ​​described above flattens the bendable portion 21 by stretching and contracting in the thickness direction. Another type of elastic sheet 32, which can also flatten the bendable portion 21, will be introduced below.

[0104] like Figure 10 As shown, the elastic element 32 is a relatively thin metal spring. One end of the metal spring is fixed to the fuselage part 11 of the fuselage 1, and the other end of the metal spring is raised relative to the fuselage part 11 and is positioned opposite the center line L. Figure 11 As shown, the metal shrapnel is compressed between the bendable part 21 and the fuselage 1.

[0105] like Figure 10As shown, each elastic piece 32 includes two parts, i.e. a fixed part and a raised part, the fixed part is used to be fixed with the body part 11, and the raised part is raised relative to the body part 11, and the raised part can rotate relative to the fixed part around the connection, so that the elastic piece 32 has elasticity.

[0106] As shown, the position of the end of the raised part away from the fixed part and the center line L of the bendable part 21 are opposite, for example, both are in the same vertical plane.

[0107] In this way, when the folding terminal is switched from the folded state to the flat state, as shown, the raised part of the elastic piece 32 and the bendable part 21 are in close contact, and the elastic piece 32 applies an action force to the bendable part 21 which is perpendicular to the bendable part 21 and points to the bendable part 21, so as to flatten the bendable part 21. Figure 11

[0108] In this embodiment, the specific structure of the elastic piece 32 is not limited, and the elastic piece 32 and the bendable part 21 can be in close contact to straighten the bendable part 21 when the folding terminal is in the flat state.

[0109] Based on the above description, the flattening piece 3 which can apply an action to the bendable part 21 to flatten the bendable part 21 when the folding terminal is in the flat state can include the following schemes.

[0110] Scheme one, the flattening piece 3 includes the two sets of limiting protrusions 31 described above, each set of limiting protrusions 31 includes a first protrusion 311 and a second protrusion 312, when the folding terminal is in the flat state, the second protrusion 312 generates a pushing force on the first protrusion 311 of the same group, so that the bendable part 21 fixedly connected with the first protrusion 311 is stretched and flattened.

[0111] Scheme two, the flattening piece 3 can include the two elastic pieces 32 described above, the elastic piece 32 can have compression elasticity along the thickness direction, or can be a metal elastic sheet. When the folding terminal is in the flat state, the elastic piece 32 applies an action force to the bendable part 21 which is perpendicular to the bendable part 21 and points to the bendable part 21, so as to flatten the bendable part 21 under pressure.

[0112] Scheme three, the flattening piece 3 can include both the two sets of limiting protrusions 31 described above and the two elastic pieces 32 described above, and the limiting protrusions 31 and the elastic pieces 32 jointly act to flatten the bendable part 21 when the folding terminal is in the flat state.

[0113] ​In the scheme shown in the present application, the folding terminal includes a flattening piece, and in the flattened state, the flattening piece can exert a force on the bendable part of the display screen to flatten the bendable part. After the folding terminal switches from the folded state to the flattened state, the display screen of the folding terminal can be flattened in the bending area, thereby enhancing the visual effect for the user and improving the user experience.

[0114] The present application also provides a folding terminal, which can be a mobile phone, a tablet computer, a display, etc.

[0115] The folding terminal switches between flattening and folding under the action of a folding mechanism. Since the improvement of the present embodiment is not in the folding mechanism, the folding mechanism is not shown in the drawings.

[0116] The folding terminal can be a terminal capable of left-right folding, or it can also be a terminal capable of up-down folding. The present embodiment does not limit whether the folding terminal is left-right folding or up-down folding, and the drawings can be exemplified by left-right folding.

[0117] The folding of the folding terminal can be inward folding or outward folding. Inward folding means that the display screen is located inside after the folding terminal is folded. Outward folding means that the display screen is located outside after the folding terminal is folded.

[0118] As shown in Figure 12 The folding terminal includes a body 1 and a display screen 2, and the display screen 2 is laid on the surface of the body 1. The body 1 is a component for supporting and fixing the display screen 2, which can be a middle frame or a structure including the middle frame.

[0119] The display screen 2 is a flexible display screen, and since the display screen 2 is a flexible display screen, it has weak rigidity and generally needs a reinforcing piece to support it. Therefore, the display screen 2 can include a reinforcing piece and a screen, and the reinforcing piece and the screen are attached to form the display screen 2. The reinforcing piece can be a steel sheet (Steel Use Stainless, SUS). Therefore, the display screen 2 described below can be the reinforcing piece of the display screen 2, or the display screen 2 can be the assembly after the reinforcing piece and the screen are attached.

[0120] The present embodiment does not limit the specific structure of the body 1 and the display screen 2, and the following will introduce the scheme for realizing the flattening of the display screen 2 in the bending area.

[0121] In one example, since the folding terminal can be folded, the body 1 can include a plurality of body parts 11, and adjacent two body parts 11 are rotationally connected, and the adjacent two body parts 11 can be rotationally connected under the action of a folding structure.

[0122] For example, the body 1 includes two body parts 11, and the folding terminal can be folded into a double screen. For another example, the body 1 includes three body parts 11, and the folding terminal can be folded into a triple screen. In this embodiment, the number of body parts 11 included in the body 1 is not limited, and two adjacent body parts 11 can be exemplified.

[0123] In order to adapt to the folding of the folding terminal, the display screen 2 includes at least one bendable part 21. The part of the display screen 2 other than the bendable part 21 is used to be fixed with the body 1, which can be referred to as a fixed part 22. Therefore, the display screen 2 includes at least one bendable part 21 and multiple fixed parts 22, and each bendable part 21 is located between two adjacent fixed parts 22.

[0124] For example, if the folding terminal can be folded into a double screen, the number of bendable parts 21 is one, and the number of fixed parts 22 is two. For another example, if the folding terminal can be folded into a triple screen, the number of bendable parts 21 is two, and the number of fixed parts 22 is three. In this embodiment, the number of bendable parts 21 and the number of fixed parts 22 included in the display screen 2 are not limited, and one bendable part 21 and two fixed parts 22 adjacent to the bendable part 21 can be exemplified.

[0125] As shown in Figure 13 When the display screen 2 is in the unfolded state, the bendable part 21 is in close contact with the body 1. In this embodiment, the bendable part 21 is in close contact with the body 1, that is, the bendable part 21 and the body 1 are in contact and have a mutual extrusion force.

[0126] As shown in Figure 13 The bendable part 21 is in close contact with the body 1, that is, a part of the bendable part 21 is in close contact with one body part 11 of the body 1, and another part of the bendable part 21 is in close contact with another body part 11 of the body 1.

[0127] In this way, when the folding terminal is in the unfolded state, if the bendable part 21 collapses, the body 1 applies an extrusion force to the bendable part 21 to make the bendable part 21 unfold, because the bendable part 21 is in close contact with the body 1.

[0128] In an example, since the bendable part 21 is prone to collapse or bulge at the crease, for example, the bendable part 21 is prone to collapse or bulge at the center line L, as shown in Figure 12 and referring to Figure 13 The thickness of the bendable part 21 can gradually decrease from the center line L to both sides of the center line L.

[0129] Of course, the thickness of the bendable portion 21 at each position can also be equal, that is, the thickness of the bendable portion 21 at each position from the center line L to both sides of the center line L is equal.

[0130] In an example, the folding terminal can also include the flattening piece 3 described above, wherein the flattening piece 3 can include the limiting protrusion 31 described above, can also include the elastic piece 32 described above, and can also include the limiting protrusion 31 and the elastic piece 32.

[0131] In the scheme shown in the present application, when the folding terminal is in the flattened state, because the bendable portion and the body are in close contact, if the bendable portion collapses, the body will exert a squeezing force on the bendable portion, prompting the bendable portion to flatten, and thus the display screen of the folding terminal can be flattened in the bending area, thereby enhancing the visual effect of the user and improving the user experience.

[0132] It should be understood that the present application is not limited to the precise construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the application should only be limited by the appended claims.
