[0077] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0078] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0079] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0080] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0081] This disclosure provides a portable mobile terminal, as shown in Figures 1-24. The portable mobile terminal has a usage state and a storage state. The portable mobile terminal may include a flexible display screen 1, a flexible keyboard 20, and a connecting structure 3. The flexible display screen 1 is foldable or rollable and has a display surface 1a and a non-display surface 1b arranged opposite each other. The flexible keyboard 20 is foldable or rollable and has key surfaces 2a and non-key surfaces 2b arranged opposite each other. The connecting structure 3 connects the flexible display screen 1 and the flexible keyboard 20 so that the flexible display screen 1 and the flexible keyboard 20 are rotatably connected. In both the usage state and the storage state, the flexible display screen 1 and the flexible keyboard 20 are connected as one unit.

[0082] The portable mobile terminal disclosed herein, on the one hand, eliminates the need to use a portion of the flexible display screen 1 as a virtual keyboard, thus ensuring both the display area and maintaining the user's usual usage habits; on the other hand, different areas of the flexible display screen 1 will not be in different usage states for extended periods, ensuring that the flexible display screen 1 will not exhibit display differences; furthermore, both the flexible display screen 1 and the flexible keyboard 20 can be folded or rolled up to form a storage state, in which the flexible display screen 1 and the flexible keyboard 20 are connected as one unit, making it convenient to carry.

[0083] In this exemplary embodiment, referring to FIG2, the flexible display screen 1 can be configured as a rectangle. Specifically, the flexible display screen 1 has two opposing long sides extending along the first direction X and two opposing short sides extending along the second direction Y. Of course, in some other exemplary embodiments of this disclosure, the flexible display screen 1 can also be configured as a trapezoid, rhombus, or other quadrilaterals, and the flexible display screen 1 can also be configured as other various polygons, which will not be described in detail here.

[0084] The flexible display screen 1 can be folded or rolled up. The side of the flexible display screen 1 that displays the image is the display surface 1a, and the side opposite to the display surface 1a is the non-display surface 1b.

[0085] The flexible display screen 1 may include a first support plate 101 and a flexible display panel 102. The flexible display panel 102 may be an OLED (Organic Light Emitting Diode) flexible display panel, a flexible LED (Light Emitting Diode) display panel, a flexible liquid crystal display (LCD), a flexible electrophoretic display (EPD), etc.

[0086] At least two first support plates 101 are provided. For example, there may be two, three, or more first support plates 101. The first support plates 101 are attached to the non-display surface 1b of the flexible display panel 102 that is opposite to the display surface 1a. The first support plates 101 extend along the second direction Y, and at least two first support plates 101 are arranged sequentially along the first direction X, so that the flexible display screen 1 can be folded or rolled up in the first direction X.

[0087] Of course, in some other exemplary embodiments of this disclosure, the first support plate 101 may extend along the first direction X, and at least two first support plates 101 may be arranged sequentially along the second direction Y, so that the flexible display screen 1 can be folded or rolled up in the second direction Y.

[0088] In some exemplary embodiments of this disclosure, the flexible display screen 1 may be a foldable display screen. The flexible display screen 1 may include at least two flat sections 11 sequentially rotatably connected along a first direction X. Specifically, the flexible display screen 1 may include a bending section and flat sections 11. At least two flat sections 11 may be provided; for example, two, three, or more flat sections 11 may be provided. At least one bending section may be provided; for example, one, two, or more bending sections may be provided.

[0089] The bent portion connects two adjacent flat plate portions 11 along the first direction X; when there are two flat plate portions 11 and one bent portion, the flat plate portion 11, the bent portion, and the flat plate portion 11 are connected sequentially along the first direction X; when there are three flat plate portions 11 and two bent portions, the flat plate portion 11, the bent portion, the flat plate portion 11, the bent portion, and the flat plate portion 11 are connected sequentially along the first direction X. Generally, the number of bent portions is one less than the number of flat plate portions 11.

[0090] The flexible display screen 1 can be bent at the bending point, thereby folding the flexible display screen 1 in the first direction X to form a stowed state.

[0091] Of course, in some other exemplary embodiments of this disclosure, the bent portion may be connected between two adjacent flat portions 11 along the second direction Y; when there are two flat portions 11 and one bent portion, the flat portion 11, the bent portion, and the flat portion 11 are connected sequentially along the second direction Y; when there are three flat portions 11 and two bent portions, the flat portion 11, the bent portion, the flat portion 11, the bent portion, and the flat portion 11 are connected sequentially along the second direction Y. The flexible display screen 1 can be bent at the bent portion, thereby folding the flexible display screen 1 in the second direction Y to form a stowed state.

[0092] In this example embodiment, there are multiple first support plates 101, some of which together with the flexible display panel 102 form the flat plate portion 11 of the flexible display screen 1, and the multiple first support plates 101 located between two adjacent flat plate portions 11 together with the flexible display panel 102 form the bent portion of the flexible display screen 1.

[0093] When the flexible display screen 1 is a foldable display screen, the number and area of ​​the first support plate 101 can be set according to the number of folds and area that the flexible display screen 1 needs to be folded into. For example, if the flexible display screen 1 needs to be folded into three folds in the first direction X, then three first support plates 101 arranged in sequence along the first direction X are required; if the flexible display screen 1 needs to be folded into two folds in the second direction Y, then two first support plates 101 arranged in sequence along the second direction Y are required.

[0094] In some exemplary embodiments of this disclosure, the flexible display screen 1 can be a rollable display screen, capable of being rolled up and deformed into a wavy shape, a cylindrical shape, etc. Of course, the wavy shape or the cylindrical shape can be formed by connecting multiple short straight lines.

[0095] When the flexible display screen 1 is a rollable display screen, the first support plate 101 is set in a long strip shape, the number of first support plates 101 is set to be large, and the width of the first support plate 101 is set to be narrow, so that the flexible display screen 1 can be rolled up. Of course, the flexible display screen 1 with this structure can also be folded.

[0096] In this exemplary embodiment, referring to FIG3, the flexible keyboard 20 may include a physical keyboard 2. The physical keyboard 2 may be rectangular, specifically, the physical keyboard 2 has two opposing long sides extending along a first direction X and two opposing short sides extending along a second direction Y. Of course, in some other exemplary embodiments of this disclosure, the physical keyboard 2 may also be trapezoidal, rhomboid, or other quadrilaterals, or other polygons, which will not be described in detail here.

[0097] The long side of the keyboard is connected to the long side of the screen through connection structure 3, so that the structure of the connected portable mobile terminal is basically the same as that of the non-portable mobile terminal, which conforms to the user's usage habits.

[0098] In this example embodiment, the shape of the largest surface of the physical keyboard 2 can be the same as the shape of the largest surface of the flexible display screen 1, and the area of ​​the largest surface of the physical keyboard 2 can be the same as the area of ​​the largest surface of the flexible display screen 1, facilitating the folding of the physical keyboard 2 and the flexible display screen 1 together. Of course, the shape of the largest surface of the physical keyboard 2 can also be different from the shape of the largest surface of the flexible display screen 1, and the area of ​​the largest surface of the physical keyboard 2 can also be different from the area of ​​the largest surface of the flexible display screen 1.

[0099] A Physical Keyboard 2 is a physical keyboard that connects to devices such as computers, tablets, and smartphones for inputting characters and performing various operations. Compared to virtual keyboards, Physical Keyboard 2 has the following characteristics: Physical Keyboard 2 features physical keys, each with independent physical tactile feedback and rebound, allowing users to perceive the triggering and release of keys while typing. This physical key feedback helps reduce typing errors and improve typing speed. Physical Keyboard 2 layouts typically conform to standard keyboard layouts, including letters, numbers, symbols, and function keys, enabling users to quickly and accurately input text and perform various operations. Physical Keyboard 2 is usually designed ergonomically, providing a comfortable feel and user experience. Appropriate key spacing, keyboard tilt angles, and wrist support designs help reduce hand fatigue and discomfort. Physical Keyboard 2 typically has various multi-function keys, such as function keys, shortcut keys, and multimedia control keys. These keys can be used for quick access to specific functions, switching applications, adjusting volume, and controlling media playback. Physical Keyboard 2 is usually made of durable materials, offering high reliability and stability. They can withstand prolonged use and typing without easily experiencing keyboard malfunctions or sticky keys.

[0100] The physical keyboard 2 can be folded or rolled up. The side of the physical keyboard 2 with keys is called the key surface 2a, the side opposite the key surface 2a is called the non-key surface 2b, and the side connecting the key surface 2a and the non-key surface 2b is the side of the physical keyboard 2.

[0101] In this example embodiment, referring to FIG3, the physical keyboard 2 may include a second support plate 201 and a flexible physical keyboard 202. The flexible physical keyboard 202 may be a silicone soft keyboard or a segmented traditional keyboard. Alternatively, a flexible touch display panel with touch functionality can be used as the flexible keyboard 20. That is, the flexible keyboard 20 may include a flexible touch display panel that can display a keyboard pattern, and the user can use the keyboard pattern to access the keyboard functions. The resolution of the flexible touch display panel can be set relatively low, that is, the resolution of the flexible touch display panel can be lower than the resolution of the flexible display panel 102 used for display.

[0102] At least two second support plates 201 are provided. For example, there may be two second support plates 201, or three or more second support plates 201. The second support plates 201 are attached to the non-key surface 2b of the flexible physical keyboard 202, which is opposite to the key surface 2a. The second support plates 201 extend along the second direction Y, and at least two second support plates 201 are arranged sequentially along the first direction X, so that the physical keyboard 2 can be folded or rolled up in the first direction X.

[0103] Of course, in some other example embodiments of this disclosure, the second support plate 201 may extend along the first direction X, and at least two second support plates 201 may be arranged sequentially along the second direction Y, so that the physical keyboard 2 can be folded or rolled up in the second direction Y.

[0104] In some exemplary embodiments of this disclosure, the physical keyboard 2 may be a foldable physical keyboard 2. The physical keyboard 2 may include at least two keyboard portions 21 that are rotatably connected sequentially along a first direction X.

At least two keyboard portions 21 may be provided; for example, two keyboard portions 21 may be provided, or three or more keyboard portions 21 may be provided. At least one bent connecting portion may be provided; for example, one bent connecting portion may be provided, or two or more bent connecting portions may be provided.

[0105] The bent connecting portion connects two adjacent keyboard portions 21 along the first direction X. When there are two keyboard portions 21 and one bent connecting portion, the keyboard portions 21, the bent connecting portion, and the keyboard portions 21 are connected sequentially along the first direction X. When there are three keyboard portions 21 and two bent connecting portions, the keyboard portions 21, the bent connecting portion, the keyboard portions 21, the bent connecting portion, and the keyboard portions 21 are connected sequentially along the first direction X. Generally, the number of bent connecting portions is one less than the number of keyboard portions 21.

[0106] The physical keyboard 2 can be bent at the bending connection, thereby folding the physical keyboard 2 in the first direction X to form a stowed state.

[0107] Of course, in some other exemplary embodiments of this disclosure, the bent connecting portion may also be connected between two adjacent keyboard portions 21 along the second direction Y; when there are two keyboard portions 21 and one bent connecting portion, the keyboard portions 21, the bent connecting portion, and the keyboard portions 21 are connected sequentially along the second direction Y; when there are three keyboard portions 21 and two bent connecting portions, the keyboard portions 21, the bent connecting portion, the keyboard portions 21, the bent connecting portion, and the keyboard portions 21 are connected sequentially along the second direction Y. The physical keyboard 2 can be bent at the bent connecting portion, thereby folding the physical keyboard 2 in the second direction Y to form a stowed state.

[0108] In this example embodiment, multiple second support plates 201 are provided, wherein some of the second support plates 201 together with the flexible physical keyboard 202 form the keyboard portion 21 of the physical keyboard 2, and multiple second support plates 201 located between two adjacent keyboard portions 21 form the bending connection portion of the physical keyboard 2 with the flexible physical keyboard 202.

[0109] When the physical keyboard 2 is a foldable physical keyboard 2, the number and area of ​​the second support plate 201 can be set according to the number of folds and area that the physical keyboard 2 needs to be folded into. For example, if the physical keyboard 2 needs to be folded into three folds in the first direction X, three second support plates 201 arranged in sequence along the first direction X are required; if the physical keyboard 2 needs to be folded into two folds in the second direction Y, two second support plates 201 arranged in sequence along the second direction Y are required.

[0110] In some exemplary embodiments of this disclosure, the physical keyboard 2 is a curlable physical keyboard 2, capable of being curled and deformed into a wavy shape, a cylindrical shape, etc. Of course, the wavy shape or the cylindrical shape can be formed by connecting multiple short straight lines.

[0111] In the case of a rollable physical keyboard 2, the second support plate 201 is set in a long strip shape, the number of second support plates 201 is set to be large, and the width of the second support plate 201 is set to be narrow, so that the physical keyboard 2 can be rolled up. Of course, this type of physical keyboard 2 can also be folded.

[0112] In this example embodiment, referring to Figures 4 and 5, the connection structure 3 may include a connector 33, a first connecting part 31, and a second connecting part 32; the first connecting part 31 is connected between the flexible display screen 1 and the connector 33, and the second connecting part 32 is connected between the physical keyboard 2 and the connector 33.

[0113] The connector 33 may include connecting shafts 331, with at least two connecting shafts 331 arranged in parallel. For example, as shown in FIG4, there may be two connecting shafts 331, making the connector 33 a two-axis connector 33; as shown in FIG5, there may be three connecting shafts 331, making the connector 33 a three-axis connector 33; or there may be multiple connecting shafts 331, making the connector 33 a multi-axis connector 33. Each connecting shaft 331 is provided with a gear 332, and the gears 332 on adjacent connecting shafts 331 mesh. Due to the friction between the tooth surfaces of the meshing gears 332, the meshing gears 332 will not rotate relative to each other without the application of external force, thereby enabling the connector 33 to have a stop-and-go function.

[0114] Referring to Figure 4, taking a two-axis connector as an example, the two-axis connector may include a first connecting shaft 331a and a second connecting shaft 331b, which are arranged parallel to each other. A first gear 332a is provided on the first connecting shaft 331a, and a second gear 332b is provided on the second connecting shaft 331b, with the first gear 332a and the second gear 332b meshing with each other. One end of the first connecting part 31 is connected to the first connecting shaft 331a, and the mounting plane of the first connecting part 31 is connected to the flexible display screen 1. One end of the second connecting part 32 is connected to the second connecting shaft 331b, and the mounting plane of the second connecting part 32 is connected to the physical keyboard 2.

[0115] Referring to Figure 5, taking a three-axis connector as an example, the three-axis connector may include a first connecting shaft 331a, a second connecting shaft 331b, and a third connecting shaft 331c. The first connecting shaft 331a, the second connecting shaft 331b, and the third connecting shaft 331c are arranged in parallel and adjacent to each other. A first gear 332a is provided on the first connecting shaft 331a, a second gear 332b is provided on the second connecting shaft 331b, and a third gear 332c is provided on the third connecting shaft 331c. The first gear 332a meshes with the second gear 332b, and the second gear 332b meshes with the third gear 332c. One end of the first connecting part 31 is connected to the first connecting shaft 331a, and the mounting plane of the first connecting part 31 is connected to the flexible display screen 1. One end of the second connecting part 32 is connected to the third connecting shaft 331c, and the mounting plane of the second connecting part 32 is connected to the physical keyboard 2.

[0116] The structure of multi-axis connectors is similar to that of tri-axis connectors, and will not be described in detail here.

[0117] In some other exemplary embodiments of this disclosure, the connection structure 3 may be a hinge, and the axis of the hinge connected to the flexible display screen 1 may be driven to rotate by a motor, and a stop-and-go function may be realized.

[0118] The above describes the specific structure of the flexible display screen 1, the physical keyboard 2, and the connecting structure 3. The following describes the installation position of the connecting structure 3 and the folding structure of the flexible display screen 1 and the physical keyboard 2.

[0119] Referring to FIG1, at least one of the at least two flat sections 11 is a display screen fixing section 11a, and the rest are display screen folding sections 11b. The display screen fixing section 11a is the part that does not need to be rotated when the flexible display screen 1 is folded, and correspondingly, the display screen folding section 11b is the part that needs to be rotated when the flexible display screen 1 is folded.

[0120] At least one of the two keyboard sections 21 is a keyboard fixing section 21a, and the rest are keyboard folding sections 21b. The keyboard fixing section 21a is the part that does not need to be rotated when the physical keyboard 2 is folded, and correspondingly, the keyboard folding section 21b is the part that needs to be rotated when the physical keyboard 2 is folded.

[0121] When the flexible display screen 1 is folded, the display screen fixing part 11a does not need to be rotated and folded. Similarly, when the physical keyboard 2 is folded, the keyboard fixing part 21a does not need to be rotated and folded. There is no relative movement between the display screen fixing part 11a and the keyboard fixing part 21a. Connecting the connecting structure 3 between the display screen fixing part 11a and the keyboard fixing part 21a ensures the connection effect between the flexible display screen 1 and the physical keyboard 2. This prevents relative movement when the flexible display screen 1 or the physical keyboard 2 is folded, which could generate tension on the connecting structure 3, causing damage to the connecting structure 3 and affecting the connection effect between the flexible display screen 1 and the physical keyboard 2. Furthermore, it ensures the folding effect of the keyboard folding part 21b and the display screen folding part 11b, thereby ensuring the folding effect of the portable mobile terminal and preventing unfolding force when stored.

[0122] In this exemplary embodiment, referring to FIG1, the flexible display screen 1 may include two display screen folding portions 11b and one display screen fixing portion 11a; the display screen folding portions 11b, the display screen fixing portion 11a, and the display screen folding portions 11b are sequentially connected along a first direction X, that is, the display screen fixing portion 11a is disposed between two adjacent display screen folding portions 11b. The physical keyboard 2 may include two keyboard folding portions 21b and one keyboard fixing portion 21a; the keyboard folding portions 21b, the keyboard fixing portion 21a, and the keyboard folding portions 21b are sequentially connected along a first direction X, that is, the keyboard fixing portion 21a is disposed between two adjacent keyboard folding portions 21b. The connecting structure 3 connects the display screen fixing portion 11a and the keyboard fixing portion 21a located in the middle. This allows the two display screen folding portions 11b on both sides of the display screen fixing portion 11a to be rotated and folded, and the two keyboard folding portions 21b on both sides of the keyboard fixing portion 21a to be rotated and folded. It not only ensures the connection between the display screen fixing part 11a and the keyboard fixing part 21a, thereby ensuring the connection between the flexible display screen 1 and the physical keyboard 2; but also enables the display screen folding part 11b to fold smoothly and the keyboard folding part 21b to fold smoothly, thereby ensuring the folding effect of the flexible display screen 1 and the physical keyboard 2.

[0123] In this case, referring to FIG7, the width of the display screen fixing part 11a in the first direction X can be greater than or equal to the sum of the widths of the two display screen folding parts 11b in the first direction X, thereby allowing the flexible display screen 1 to be folded into a two-layer structure; the width of the keyboard fixing part 21a in the first direction X can be greater than or equal to the sum of the widths of the two keyboard folding parts 21b in the first direction X, thereby allowing the physical keyboard 2 to be folded into a two-layer structure. Of course, the width of the display screen fixing part 11a in the first direction X can also be less than the sum of the widths of the two display screen folding parts 11b in the first direction X, thereby allowing the flexible display screen 1 to be folded into a three-layer structure; the width of the keyboard fixing part 21a in the first direction X can also be less than the sum of the widths of the two keyboard folding parts 21b in the first direction X, thereby allowing the physical keyboard 2 to be folded into a three-layer structure.

[0124] Of course, in some other exemplary embodiments of this disclosure, the display screen fixing part 11a and at least one display screen folding part 11b may be sequentially connected along the first direction X, that is, the display screen fixing part 11a is located at the end of the entire flexible display screen 1 along the first direction X; or the keyboard fixing part 21a and at least one keyboard folding part 21b may be sequentially connected along the first direction X, that is, the keyboard fixing part 21a is located at the end of the entire physical keyboard 2 along the first direction X. Alternatively, one display screen folding part 11b may be provided on one side of the display screen fixing part 11a along the first direction X, and two display screen folding parts 11b may be provided on the opposite side of the display screen fixing part 11a along the first direction X, that is, the number of display screen folding parts 11b provided on opposite sides of the display screen fixing part 11a along the first direction X is different. Similarly, one keyboard folding part 21b may be provided on one side of the keyboard fixing part 21a along the first direction X, and two keyboard folding parts 21b may be provided on the opposite side of the keyboard fixing part 21a along the first direction X, that is, the number of keyboard folding parts 21b provided on opposite sides of the keyboard fixing part 21a along the first direction X is different.

[0125] In other example embodiments of this disclosure, the flexible display screen 1 may include at least two flat sections 11 rotatably connected in sequence along the second direction Y, so that the flexible display screen 1 can be folded in the second direction Y to form a stowed state; and the physical keyboard 2 may include at least two keyboard sections 21 rotatably connected in sequence along the second direction Y, so that the physical keyboard 2 can be folded in the second direction Y to form a stowed state; in this case, the connecting structure 3 can connect the entire long side of the physical keyboard 2 and the entire long side of the flexible display screen 1. For example, the connecting structure 3 can be set to two or three. When two connecting structures 3 are provided, the two connecting structures 3 can be connected at both ends of the long side of the physical keyboard 2 and the long side of the flexible display screen 1. When three connecting structures 3 are provided, the two connecting structures 3 can be connected at both ends of the long side of the physical keyboard 2 and the long side of the flexible display screen 1, and the third connecting structure 3 can be set between the two connecting structures 3. The three connecting structures 3 can be evenly distributed.

[0126] In some exemplary embodiments of this disclosure, referring to FIG7, in the stored state, the flexible display screen 1 covers the physical keyboard 2. When it needs to be folded up for carrying, the flexible display screen 1 and the physical keyboard 2 fold simultaneously. Specifically, referring to FIG6, the flexible display screen 1 and the physical keyboard 2 are fastened together, and the two keyboard folding portions 21b of the physical keyboard 2 and the two display screen folding portions 11b of the flexible display screen 1 fold simultaneously toward the non-key surface 2b of the physical keyboard 2. Referring to FIG7, this makes the folded flexible display screen 1 and the physical keyboard 2 almost a completely integrated structure, further facilitating carrying. Moreover, the display surface 1a of the flexible display screen 1 is adjacent to the key surface 2a of the physical keyboard 2, so that the display surface 1a of the flexible display screen 1 is located on the inside, avoiding wear and tear on the display surface 1a; and avoiding collisions with the display surface 1a; and the key surface 2a is located on the inside, avoiding accidental key presses and preventing protruding keys from colliding with other structures, which could cause keys to fall off.

[0127] Of course, in some other exemplary embodiments of this disclosure, the physical keyboard 2 can also be in a stored state, covering the flexible display screen 1. When it is necessary to fold it up for carrying, the flexible display screen 1 and the physical keyboard 2 can be folded up simultaneously. Specifically, the flexible display screen 1 and the physical keyboard 2 are fastened together, and the two keyboard folding parts 21b of the physical keyboard 2 and the two display screen folding parts 11b of the flexible display screen 1 are folded up simultaneously toward the non-display surface 1b of the flexible display screen 1, so that the folded flexible display screen 1 and the physical keyboard 2 are almost completely integrated into one structure, which further facilitates carrying.

[0128] In some exemplary embodiments of this disclosure, referring to Figures 8-10, in the folded state, the flexible display screen 1 and the physical keyboard 2 can be folded separately. For example, referring to Figure 8, the two display screen folding portions 11b of the flexible display screen 1 are folded toward the display surface 1a to form a two-layer structure, so that the display surface 1a of the flexible display screen 1 is located on the inside, avoiding wear and tear on the display surface 1a and preventing collisions with it. Referring to Figure 9, the two keyboard folding portions 21b of the physical keyboard 2 are also folded toward the key surface 2a to form a two-layer structure, so that the key surface 2a of the physical keyboard 2 is located on the inside, avoiding accidental key presses and preventing protruding keys from colliding with other structures, thus preventing keys from falling off. Referring to Figure 10, the flexible display screen 1 is also stacked on one side of the physical keyboard 2, that is, the folded flexible display screen 1 is stacked on one side of the folded physical keyboard 2.

[0129] In this case, since both the flexible display screen 1 and the physical keyboard 2 are folded inward, it is necessary to consider accommodating the folded display screen fold 11b and the keyboard fold 21b after folding. Therefore, a three-axis connector 33 or a multi-axis connector 33 can be used to make the distance between the flexible display screen 1 and the physical keyboard 2 larger, with enough space to accommodate the folded display screen fold 11b and the keyboard fold 21b after folding.

[0130] In some exemplary embodiments of this disclosure, referring to Figures 11-15, the portable mobile terminal may further include a guide structure 4. The guide structure 4 may include guide rails, and two guide rails may be provided. The guide structure 4 is located on the side of the physical keyboard 2 away from the keys and extends along the second direction Y. Specifically, the two guide rails are located on the side of the physical keyboard 2 away from the keys and are located at opposite ends in the first direction X. The two guide rails extend along the second direction Y, so that when stored, the flexible display screen 1 can be inserted into the guide structure 4 along the second direction Y. This allows the two ends of the flexible display screen 1 to be inserted into the guide structure 4 in the stored state, and the guide structure 4 can limit the two ends of the flexible display screen 1.

[0131] In this case, as shown in FIG12, the portable mobile terminal has an unfolded state. In the unfolded state, the display surface 1a of the flexible display screen 1 is basically parallel to the key surface 2a of the physical keyboard 2, and the flexible display screen 1 and the physical keyboard 2 do not overlap. The flexible display screen 1 is rotated so that the connecting structure 3 is basically flat. The first connecting part 31 and the second connecting part 32 are basically located on the same plane. The display surface 1a of the flexible display screen 1 and the key surface 2a of the physical keyboard 2 are basically parallel to each other to form an unfolded state.

[0132] In the unfolded state, as shown in FIG13, the flexible display screen 1 and the physical keyboard 2 are located on opposite sides of the third direction Z of the connecting structure 3. The third direction Z is perpendicular to the key surface 2a, that is, the third direction Z is perpendicular to both the first direction X and the second direction Y. Specifically, the physical keyboard 2 is connected to the inner side of the first connecting part 31, and the flexible display screen 1 is connected to the outer side of the first connecting part 31. The inner side is the side where the first connecting part 31 and the second connecting part 32 are close to each other after being fastened, and the outer side is the side where the first connecting part 31 and the second connecting part 32 are far apart after being fastened.

[0133] Referring to FIG13, the portable mobile terminal may further include a connectable and detachable structure 5. In the use state, the flexible display screen 1 and the connecting structure 3 are connected through the connectable and detachable structure 5. In the storage state, the flexible display screen 1 and the connecting structure 3 are detached through the connectable and detachable structure 5.

[0134] The connectable / detachable structure 5 may include an electromagnet 51 and a suction part 52. Specifically, an electromagnet 51 may be provided on the first connecting part 31, and a portion of the first support plate 101 may be a suction part 52 that can be attracted by the electromagnet 51. The suction part 52 is made of iron. When the electromagnet 51 is energized, the electromagnet 51 attracts the suction part 52 of the first support plate 101, thereby fixing the flexible display screen 1 to the connecting structure 3. When the electromagnet 51 is de-energized, the flexible display screen 1 is detached from the connecting structure 3.

[0135] Of course, in some other exemplary embodiments of this disclosure, an electromagnet may be provided on the first support plate 101, and a portion of the first connecting part 31 may be a attracting part that can be attracted by the electromagnet. When the electromagnet is energized, the electromagnet attracts the attracting part of the first connecting part 31, thereby fixing the flexible display screen 1 to the connecting structure 3. When the electromagnet is de-energized, the flexible display screen 1 is detached from the connecting structure 3.

[0136] Pushing the flexible display screen 1 will push it to the non-key surface 2b of the physical keyboard 2. The guide structure 4 can guide the movement of the flexible display screen 1 and limit its movement to a certain extent, preventing the flexible display screen 1 from detaching from the physical keyboard 2, which is beneficial for subsequent folding.

[0137] Referring to FIG14, the length of the first connecting part 31 in the first direction X can be set to be relatively long. The first connecting part 31 may include two side plates 311, which are disposed on both sides of the flexible display screen 1 in the first direction X.

[0138] The connectable / disconnectable structure 5 can be a snap-fit ​​structure. This snap-fit ​​structure may include a connecting hole 3111 on the side plate 311 of the first connecting part 31, and a mounting hole 1011 on the side wall of the first support plate 101. An elastic element 53 is fixed within the mounting hole 1011. The elastic element 53 can be a coil spring, a rubber component, a plastic component, etc. One end of the elastic element 53 is fixed to the bottom wall of the mounting hole 1011, and a pin 54 is fixed to the opposite end of the elastic element 53. That is, one end of the pin 54 is fixed to the elastic element 53, and the opposite end face of the pin 54 is spherical. The pin 54, engaged in the connecting hole 3111, securely connects the flexible display screen 1 to the connecting structure 3. Pushing the flexible display screen 1 forcefully causes the pin 54 to disengage from the connecting hole 3111, thus detaching the flexible display screen 1 from the connecting structure 3.

[0139] The first connecting part 31 can be configured as multiple segments along the first direction and connected by a hinge structure, so that the first connecting part 31 can be folded together with the physical keyboard 2.

[0140] In this configuration, as shown in Figure 15, in the stowed state, the flexible display screen 1 covers the physical keyboard 2. When it needs to be folded up for carrying, the flexible display screen 1 and the physical keyboard 2 fold simultaneously. Specifically, as shown in Figure 12, the flexible display screen 1 and the physical keyboard 2 are opened to the unfolded state. The flexible display screen 1 is detached from the connectable / detachable structure 5. The flexible display screen 1 is pushed so that it inserts into the guide structure 4. The two keyboard folding parts 21b of the physical keyboard 2 and the two display screen folding parts 11b of the flexible display screen 1 are simultaneously folded toward the key surface 2a of the physical keyboard 2. As shown in Figure 15, the folded flexible display screen 1 and the physical keyboard 2 become almost a single integrated structure, further facilitating carrying. Moreover, the display surface 1a of the flexible display screen 1 is adjacent to the non-key surface 2b of the physical keyboard 2, so that the display surface 1a of the flexible display screen 1 is located on the inside, avoiding wear and tear on the display surface 1a; and avoiding collisions with the display surface. The key surface 2a is located on the inside, avoiding accidental key presses and preventing protruding keys from colliding with other structures, which could cause keys to fall off.

[0141] In some exemplary embodiments of this disclosure, referring to Figures 16-20, the first spool 72 is indicated by dashed lines because it is obscured by the first roll 7. The portable mobile terminal may also include a guide rail structure 6 and a first roll 7, with the first roll 7 located on one side of the guide rail structure 6 in the first direction X. The guide rail structure 6 and the first roll 7 form a rectangular frame. Specifically, referring to Figure 17, the guide rail structure 6 may include a first guide rail 61, a second guide rail 62, and a third guide rail 63. Each of the first guide rail 61, the second guide rail 62, and the third guide rail 63 has a guide groove for accommodating the edge of the flexible display screen 1. The length of the first guide rail 61 is substantially the same as the length of the third guide rail 63 and is greater than the length of the flexible display screen 1. The length of the second guide rail 62 is substantially the same as the length of the first roll 7 and is greater than the width of the flexible display screen 1. The first guide rail 61, the second guide rail 62, the third guide rail 63, and the first roll 7 are connected end to end to form a rectangular frame. In use, the flexible display screen 1 can be located within the guide rail structure 6.

[0142] The guide rail structure 6 is connected to the connecting structure 3. Specifically, the first guide rail 61 is connected to the first connecting part 31. The flexible display screen 1 is slidably connected to the guide rail structure 6.

[0143] Referring to Figures 16-19, a first opening 71 is provided on the first roll 7. The first opening 71 extends along the axial direction of the first roll 7, and the length of the first opening 71 is basically the same as the width of the flexible display screen 1. A first spool 72 is rotatably connected inside the first roll 7. Specifically, a first spool 72 is provided inside the first roll 7. The first spool 72 extends along the axial direction of the first roll 7, and both ends of the first spool 72 can be rotatably connected inside the first roll 7 through bearings.

[0144] In the usage state, as shown in FIG16, one end of the flexible display screen 1 is connected to the first roll 7 through the first opening 71, and the rest of the flexible display screen 1 is unfolded outside the first roll 7. In the storage state, as shown in FIG19 and FIG20, the flexible display screen 1 is rolled up inside the first roll 7 and wound on the first spool 72. Moreover, the tail end of the flexible display screen 1 remains outside the first roll 7 to facilitate the unfolding of the flexible display screen 1 during use. The tail end is the end opposite to the end connected to the first spool 72.

[0145] The portable mobile terminal may also include a first drive mechanism 91, which may be a rotary motor with a drive shaft fixedly connected to a first roll 72. The rotary motor rotates in the forward direction to drive the first roll 72 to rotate, and the rotation of the first roll 72 rolls the flexible display screen 1 onto the first roll 72. The rotary motor rotates in the reverse direction to drive the first roll 72 to rotate, so that the flexible display screen 1 unfolds outside the first roll 7.

[0146] In this case, the physical keyboard 2 is a foldable physical keyboard 2, which may include at least two keyboard parts 21 that are rotatably connected in sequence along the first direction X, so that the physical keyboard 2 can be folded in the first direction X to form a storage state. The specific structure of the foldable physical keyboard 2 has been described in detail above, so it will not be repeated here.

[0147] Referring to FIG17, the guide rail structure 6 may include at least two guide rail portions 6a and a hinge structure 6b, wherein at least two guide rail portions 6a are connected sequentially along a first direction X; for example, the guide rail structure 6 may include two guide rail portions 6a, or the guide rail structure 6 may include three or more guide rail portions 6a.

[0148] The following description takes the guide rail structure 6 as an example, which may include three guide rail parts 6a. The three guide rail parts 6a are the first guide rail part 6a1, the second guide rail part 6a2, and the third guide rail part 6a3.

[0149] Specifically, the first guide rail 61 may include a first guide bar 611, a second guide bar 612, and a third guide bar 613 connected sequentially along the first direction X; the third guide rail 63 may include a fourth guide bar 631, a fifth guide bar 632, and a sixth guide bar 633 connected sequentially along the first direction X; the first guide bar 611 and the fourth guide bar 631 are both connected to the first drum 7 and are included in the first guide rail portion 6a1; the third guide bar 613 and the sixth guide bar 633 are both connected to the second guide rail 62 and are included in the third guide rail portion 6a3; the second guide bar 612 and the fifth guide bar 632, located in the middle, are included in the second guide rail portion 6a2.

[0150] The hinge structure 6b connects two adjacent guide rail sections 6a so that the guide rail structure 6 can be folded in the stored state. For example, there can be four hinge structures 6b, namely the first hinge structure 6b1, the second hinge structure 6b2, the third hinge structure 6b3, and the fourth hinge structure 6b4.

[0151] The first hinge structure 6b1 may include a first through hole provided on the first guide bar 611, a second through hole provided on the second guide bar 612, and a first hinge shaft, the first hinge shaft passing through the first through hole and the second through hole to form the first hinge structure 6b1; the second hinge structure 6b2 may include a third through hole provided on the second guide bar 612, a fourth through hole provided on the third guide bar 613, and a second hinge shaft, the second hinge shaft passing through the third through hole and the fourth through hole to form the second hinge structure 6b2.

[0152] The third hinge structure 6b3 may include a fifth through hole provided on the fourth guide bar 631, a sixth through hole provided on the fifth guide bar 632, and a third hinge shaft, with the third hinge shaft passing through the fifth through hole and the sixth through hole to form the third hinge structure 6b3; the fourth hinge structure 6b4 may include a seventh through hole provided on the fifth guide bar 632, an eighth through hole provided on the sixth guide bar 633, and a fourth hinge shaft, with the fourth hinge shaft passing through the seventh through hole and the eighth through hole to form the fourth hinge structure 6b4.

[0153] Of course, in some other exemplary embodiments of this disclosure, the guide rail structure 6 may only include the first guide rail 61. In that case, the three guide rail parts 6a are the first guide bar 611, the second guide bar 612 and the third guide bar 613, respectively. The hinge structure 6b may be set as two, namely the first hinge structure 6b1 and the second hinge structure 6b2 mentioned above. The specific structures of the first hinge structure 6b1 and the second hinge structure 6b2 will not be described in detail here.

[0154] In this configuration, as shown in Figure 20, in the folded state, the flexible display screen 1 is rolled up inside the first roll 7, and the physical keyboard 2 is encased in the guide rail structure 6, with the guide rail structure 6 adjacent to the non-key surface 2b of the physical keyboard 2. When it needs to be folded up for transport, as shown in Figure 18, the flexible display screen 1 is rolled up inside the first roll 7. As shown in Figure 19, the guide rail structure 6 is then rotated to the key surface 2a of the physical keyboard 2. As shown in Figure 20, the two keyboard folding parts 21b of the physical keyboard 2 and the two guide rail parts 6a on both sides of the guide rail structure 6 are simultaneously folded towards the key surface 2a of the physical keyboard 2, making the folded guide rail structure 6 and the physical keyboard 2 almost a single integrated structure, further facilitating transport. Moreover, when the guide rail parts 6a of the guide rail structure 6 rotate, they cause the first roll 7 to rotate as well, so that the first roll 7 is positioned between two adjacent keyboard folding parts 21b. The key surface 2a is located on the inside, preventing accidental key presses and avoiding collisions between protruding keys and other structures, which could cause keys to fall off.

[0155] In this case, the connection structure 3 between the physical keyboard 2 and the guide rail structure 6 can be set to three, with one connection structure 3 between each keyboard part 21 and the guide rail structure 6.

[0156] In some exemplary embodiments of this disclosure, referring to FIG21-24, the flexible display screen 1 is a roll-up storage method, that is, the flexible display screen 1 can be rolled up and deformed; the physical keyboard 2 is also a roll-up storage method, that is, the physical keyboard 2 can be rolled up and deformed.

[0157] The portable mobile terminal may also include a guide rail structure 6, a first roll 7, a first spool 72, a second roll 8, and a second spool 82; the flexible display screen 1 can be unfolded and stored through the guide rail structure 6, the first roll 7, and the first spool 72. The specific structures of the guide rail structure 6, the first roll 7, and the first spool 72 have been described in detail above, so they will not be repeated here.

[0158] The second scroll 8 is provided with a second opening 81, which extends along the axial direction of the second scroll 8. The length of the second opening 81 is basically the same as the width of the physical keyboard 2. The second scroll 82 is rotatably connected inside the second scroll 8. Specifically, the second scroll 82 is provided inside the second scroll 8, which extends along the axial direction of the second scroll 8. Both ends of the second scroll 82 are rotatably connected inside the second scroll 8 through bearings.

[0159] In the usage state, as shown in FIG21, one end of the physical keyboard 2 is connected to the second reel 8 through the second opening 81, and the rest of the physical keyboard 2 is unfolded outside the second reel 8. In the storage state, as shown in FIG24, the physical keyboard 2 is rolled up inside the second reel 8 and wound on the second spool 82. Moreover, the tail end of the physical keyboard 2 remains outside the second reel 8 to facilitate unfolding when the physical keyboard 2 is in use. The tail end is the opposite end to the end connected to the second spool 82.

[0160] The portable mobile terminal may also include a second drive mechanism 92, which may be a rotary motor with a drive shaft fixedly connected to a second scroll 82. The rotary motor rotates in the forward direction to drive the second scroll 82 to rotate, and the rotation of the second scroll 82 winds the physical keyboard 2 onto the second scroll 82. The rotary motor rotates in the reverse direction to drive the second scroll 82 to rotate, so that the physical keyboard 2 unfolds outside the second scroll 82.

[0161] In this case, referring to Figure 24, in the stored state, the guide rail structure 6 is wound inside the second roll 8 and onto the second spool 82. The width of the second opening 81 on the second roll 8 can be set wider, allowing the guide rail structure 6 to extend into the second roll 8. When it needs to be folded up for carrying, referring to Figure 22, the flexible display screen 1 is wound inside the first roll 7. Referring to Figure 23, the guide rail structure 6 and the first roll 7 are then rotated together to the key surface 2a of the physical keyboard 2, so that the first roll 7 and the second roll 8 are parallel. Referring to Figure 24, the physical keyboard 2 is wound inside the second roll 8. Since the guide rail structure 6 is in contact with the key surface 2a of the physical keyboard 2, the physical keyboard 2 will drive the guide rail structure 6 to be wound together, so that most of the guide rail structure 6 is wound into the second roll 8. The unwound end of the guide rail structure 6 is connected to the first roll 7, thereby connecting the first roll 7 and the second roll 8 through the guide rail structure 6, further facilitating carrying.

[0162] The guide rail structure 6 can be made of shape memory alloy, or it can be made of flexible materials such as rubber or resin.

[0163] In this case, the connection structure 3 between the physical keyboard 2 and the guide rail structure 6 can be set at both ends of the physical keyboard 2 in the first direction X, and the connection structure 3 can be set to be relatively short, which facilitates the curling and deformation of the physical keyboard 2 and the guide rail structure 6.
