The keyboard parts 21 are provided in at least two numbers, for example, the keyboard parts 21 may be provided in two numbers, or the keyboard parts 21 may be provided in three or more numbers. The bending connection part is provided in at least one number, for example, the bending connection part may be provided in one number, or the bending connection part may be provided in two or more numbers.

[0114] The bending connection part is connected between two adjacent keyboard parts 21 along the first direction X; when there are two keyboard parts 21 and one bending connection part, the keyboard part 21, the bending connection part, and the keyboard part 21 are sequentially connected along the first direction X; when there are three keyboard parts 21 and two bending connection parts, the keyboard part 21, the bending connection part, the keyboard part 21, the bending connection part, and the keyboard part 21 are sequentially connected along the first direction X. Generally, the number of the bending connection parts is one less than the number of the keyboard parts 21.

[0115] The physical keyboard 2 can be bent at the bending connection portion, so that the physical keyboard 2 is folded in the first direction X to form a storage state.

[0116] Of course, in some other exemplary embodiments of the present disclosure, the bending connection part may be connected between two adjacent keyboard parts 21 along the second direction Y; when there are two keyboard parts 21 and one bending connection part, the keyboard part 21, the bending connection part, and the keyboard part 21 are sequentially connected along the second direction Y; when there are three keyboard parts 21 and two bending connection parts, the keyboard part 21, the bending connection part, the keyboard part 21, the bending connection part, and the keyboard part 21 are sequentially connected along the second direction Y. The physical keyboard 2 can be bent at the bending connection part, so that the physical keyboard 2 is folded in the second direction Y to form a storage state.

[0117] In this example embodiment, the second support plates 201 are arranged in plurality, wherein some of the second support plates 201 and the flexible physical keyboard 202 together form the keyboard portion 21 of the physical keyboard 2, and the plurality of second support plates 201 and the flexible physical keyboard 202 located between two adjacent keyboard portions 21 form the bending connection portion of the physical keyboard 2.

[0118] In the case where the physical keyboard 2 is a foldable physical keyboard 2, the number and area of ​​the second support plates 201 can be set according to the number of folds and the area formed by the physical keyboard 2 to be folded. For example, if the physical keyboard 2 needs to be folded in the first direction X to form three folds, three second support plates 201 arranged in sequence along the first direction X need to be set; if the physical keyboard 2 needs to be folded in the second direction Y to form two folds, two second support plates 201 arranged in sequence along the second direction Y need to be set.

[0119] In some exemplary embodiments of the present disclosure, the physical keyboard 2 is a curled physical keyboard 2 that can be curled and deformed into a wave shape, a cylinder shape, etc. Of course, the wave shape and the cylinder shape can be formed by connecting a plurality of shorter straight lines.

[0120] In the case where the physical keyboard 2 is a rolled physical keyboard 2, the second support plates 201 are arranged in a long strip shape, the number of the second support plates 201 is arranged to be large, and the width of the second support plates 201 is arranged to be narrow, so that the physical keyboard 2 can be rolled. Of course, the physical keyboard 2 of this structure can also be folded.

[0122] The connecting member 33 may include at least two connecting shafts 331 arranged in parallel; for example, referring to Figure 4 As shown, the connecting shaft 331 can be provided in two, so that the connecting member 33 can be a two-axis connecting member 33; Figure 5 As shown, the number of connecting shafts 331 can be three, so that the connecting member 33 can be a three-axis connecting member 33; the number of connecting shafts 331 can be multiple, so that the connecting member 33 can be a multi-axis connecting member 33. A gear 332 is provided on each connecting shaft 331, and the gears 332 on two adjacent connecting shafts 331 are meshed. Since there is friction between the tooth surfaces of the meshed gears 332, the meshed gears 332 will not rotate relative to each other without applying external force, so that the connecting member 33 has a stop function.

[0123] Reference Figure 4As shown, taking the two-axis connecting member as an example, the two-axis connecting member may include a first connecting shaft 331a and a second connecting shaft 331b, and the first connecting shaft 331a is arranged in parallel with the second connecting shaft 331b. A first gear 332a is arranged on the first connecting shaft 331a, and a second gear 332b is arranged on the second connecting shaft 331b, and the first gear 332a and the second gear 332b are meshed with each other. One end of the first connecting portion 31 is connected to the first connecting shaft 331a, and the mounting plane of the first connecting portion 31 is connected to the flexible display screen 1. One end of the second connecting portion 32 is connected to the second connecting shaft 331b, and the mounting plane of the second connecting portion 32 is connected to the physical keyboard 2.

A first gear 332a is arranged on the first connecting shaft 331a, a second gear 332b is arranged on the second connecting shaft 331b, and a third gear 332c is arranged on the third connecting shaft 331c. The first gear 332a and the second gear 332b are meshed with each other, and the second gear 332b and the third gear 332c are meshed with each other. One end of the first connecting portion 31 is connected to the first connecting shaft 331a, and the mounting plane of the first connecting portion 31 is connected to the flexible display screen 1. One end of the second connecting portion 32 is connected to the third connecting shaft 331c, and the mounting plane of the second connecting portion 32 is connected to the physical keyboard 2.

[0125] The structure of the multi-axis connecting member is similar to that of the tri-axis connecting member, and will not be described in detail here.

[0126] In some other exemplary embodiments of the present 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 realize a stop-and-go function.

[0127] The specific structures of the flexible display screen 1 , the physical keyboard 2 and the connection structure 3 are described above. The installation position of the connection structure 3 and the folding structure of the flexible display screen 1 and the physical keyboard 2 are described below.

[0128] Reference Figure 1 As shown, at least one of the at least two flat plate parts 11 is a display screen fixing part 11a, and the rest are display screen folding parts 11b; the display screen fixing part 11a is the part that does not need to be rotated and folded when the flexible display screen 1 is folded, and correspondingly, the display screen folding part 11b is the part that needs to be rotated and folded when the flexible display screen 1 is folded.

[0129] At least one of the at least two keyboard parts 21 is a keyboard fixing part 21a, and the others are keyboard folding parts 21b; the keyboard fixing part 21a is the part that does not need to be rotated and folded when the physical keyboard 2 is folded, and correspondingly, the keyboard folding part 21b is the part that needs to be rotated and folded when the physical keyboard 2 is folded.

[0130] When the flexible display screen 1 is folded, since the display screen fixing part 11a does not need to be rotated and folded, when the physical keyboard 2 is folded, the keyboard fixing part 21a also does not need to be rotated and folded; there will be no relative movement between the display screen fixing part 11a and the keyboard fixing part 21a, and the connecting structure 3 is connected between the display screen fixing part 11a and the keyboard fixing part 21a, which can ensure the connection effect between the flexible display screen 1 and the physical keyboard 2, and avoid relative movement when the flexible display screen 1 is folded or the physical keyboard 2 is folded, which will cause pulling force on the connecting structure 3, resulting in damage to the connecting structure 3 and affecting the connection effect between the flexible display screen 1 and the physical keyboard 2; and it can ensure 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 avoiding the generation of unfolding force when it is in the storage state.

[0131] In this example implementation, refer to Figure 1 As shown, the flexible display screen 1 may include two display screen folding parts 11b and a display screen fixing part 11a; the display screen folding part 11b, the display screen fixing part 11a and the display screen folding part 11b are sequentially connected along the first direction X, that is, the display screen fixing part 11a is arranged between two adjacent display screen folding parts 11b. The physical keyboard 2 may include two keyboard folding parts 21b and a keyboard fixing part 21a; the keyboard folding part 21b, the keyboard fixing part 21a and the keyboard folding part 21b are sequentially connected along the first direction X, that is, the keyboard fixing part 21a is arranged between two adjacent keyboard folding parts 21b. The connecting structure 3 is connected between the display screen fixing part 11a and the keyboard fixing part 21a located in the middle. The two display screen folding parts 11b on both sides of the display screen fixing part 11a can be rotated and folded, and the two keyboard folding parts 21b on both sides of the keyboard fixing part 21a can be rotated and folded. It not only ensures the connection effect between the display screen fixing part 11a and the keyboard fixing part 21a, and further ensures the connection effect between the flexible display screen 1 and the physical keyboard 2; it also enables the display screen folding part 11b to be folded smoothly, and the keyboard folding part 21b can also be folded smoothly, thereby ensuring the folding effect of the flexible display screen 1 and the physical keyboard 2.

[0132] In this case, refer to Figure 7As shown, the width of the display screen fixing portion 11a in the first direction X can be greater than or equal to the sum of the widths of the two display screen folding portions 11b in the first direction X, so that the flexible display screen 1 can be folded into a two-layer structure; the width of the keyboard fixing portion 21a in the first direction X can be greater than or equal to the sum of the widths of the two keyboard folding portions 21b in the first direction X, so that the physical keyboard 2 can be folded into a two-layer structure. Of course, the width of the display screen fixing portion 11a in the first direction X can also be less than the sum of the widths of the two display screen folding portions 11b in the first direction X, so that the flexible display screen 1 can be folded into a three-layer structure; the width of the keyboard fixing portion 21a in the first direction X can also be less than the sum of the widths of the two keyboard folding portions 21b in the first direction X, so that the physical keyboard 2 can be folded into a three-layer structure.

[0133] Of course, in some other exemplary embodiments of the present disclosure, the display screen fixing portion 11a and at least one display screen folding portion 11b may be sequentially connected along the first direction X, that is, the display screen fixing portion 11a is located at the end of the first direction X of the entire flexible display screen 1; the keyboard fixing portion 21a and at least one keyboard folding portion 21b may be sequentially connected along the first direction X, that is, the keyboard fixing portion 21a is located at the end of the first direction X of the entire physical keyboard 2. It is also possible that one display screen folding portion 11b is provided on one side of the display screen fixing portion 11a in the first direction X, and two display screen folding portions 11b are provided on the other side of the display screen fixing portion 11a in the first direction X, that is, the number of display screen folding portions 11b provided on the opposite sides of the display screen fixing portion 11a in the first direction X is different. It is also possible that one keyboard folding portion 21b is provided on one side of the keyboard fixing portion 21a in the first direction X, and two keyboard folding portions 21b are provided on the other side of the keyboard fixing portion 21a in the first direction X, that is, the number of keyboard folding portions 21b provided on the opposite sides of the keyboard fixing portion 21a in the first direction X is different.

[0134] In addition, in some other exemplary embodiments of the present disclosure, the flexible display screen 1 may include at least two flat plate parts 11 that are sequentially rotatably connected along the second direction Y, so that the flexible display screen 1 is folded in the second direction Y to form a storage state; and the physical keyboard 2 may include at least two keyboard parts 21 that are sequentially rotatably connected along the second direction Y, so that the physical keyboard 2 is folded in the second direction Y to form a storage state; in this case, the connection structure 3 may connect the entire keyboard long side of the physical keyboard 2 and the entire screen long side of the flexible display screen 1. For example, the connection structure 3 may be set to two or three. In the case of two connection structures 3, two connection structures 3 may be connected to the two ends of the keyboard long side of the physical keyboard 2 and the screen long side of the flexible display screen 1. In the case of three connection structures 3, two connection structures 3 may be connected to the two ends of the keyboard long side of the physical keyboard 2 and the screen long side of the flexible display screen 1, and the third connection structure 3 may be set between the two connection structures 3, and the three connection structures 3 may be evenly distributed.

[0135] In some example embodiments of the present disclosure, reference is made to Figure 7 As shown, in the storage state, the flexible display screen 1 is covered outside the physical keyboard 2. When it is necessary to store and carry, the flexible display screen 1 and the physical keyboard 2 are folded synchronously. Specifically, refer to Figure 6 As shown, the flexible display screen 1 is buckled with the physical keyboard 2, and the two keyboard folding parts 21b of the physical keyboard 2 and the two display folding parts 11b of the flexible display screen 1 are synchronously folded toward the non-key surface 2b of the physical keyboard 2, referring to Figure 7 As shown, the folded flexible display screen 1 and the physical keyboard 2 are almost completely integrated, which is further convenient to carry. Moreover, the display surface 1a of the flexible display screen 1 is arranged 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 inner side to avoid wear on the display surface 1a; and avoid collision with the display surface 1a; the key surface 2a is located on the inner side to avoid accidental touch of the key, and avoid collision between the protruding key and other structures, resulting in the key falling off.

[0136] Of course, in some other example embodiments of the present disclosure, the physical keyboard 2 may be wrapped around the flexible display screen 1 in the stored state, and the flexible display screen 1 and the physical keyboard 2 may be folded synchronously when they need to be folded up and carried. Specifically, the flexible display screen 1 and the physical keyboard 2 may be buckled 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 may be folded synchronously 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 a structure, which is further convenient for carrying.

[0137] In some example embodiments of the present disclosure, reference is made to Figure 8-Figure 10As shown, in the storage state, the flexible display screen 1 and the physical keyboard 2 can be folded separately, for example, referring to Figure 8 As shown, the two display folding parts 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 inside, avoiding wear and tear on the display surface 1a, and avoiding collision with the display surface 1a. Fig. 9 As shown, the two keyboard folding parts 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 inside to avoid accidental touches on the keys and to avoid collisions between protruding keys and other structures, resulting in the keys falling off. Fig.10 As shown, the flexible display screen 1 is overlapped on one side of the physical keyboard 2, that is, the folded flexible display screen 1 is overlapped on one side of the folded physical keyboard 2.

[0138] In this case, since the flexible display screen 1 and the physical keyboard 2 are both folded inward, it is necessary to consider accommodating the folded display screen folding portion 11b and the keyboard folding portion 21b. Therefore, a three-axis connector 33 or a multi-axis connector 33 can be used to increase the distance between the flexible display screen 1 and the physical keyboard 2, so that there is enough space to accommodate the folded display screen folding portion 11b and the keyboard folding portion 21b.

[0139] In some example embodiments of the present disclosure, reference is made to Figure 11-Figure 15 As shown, the portable mobile terminal may further include a guide structure 4. The guide structure 4 may include a guide rail, and the guide rail may be provided in two numbers; the guide structure 4 is provided 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 provided on the side of the physical keyboard 2 away from the keys, and are located at two opposite ends in the first direction X, and the two guide rails extend along the second direction Y, so that when the flexible display screen 1 is stored, it can be inserted into the guide structure 4 along the second direction Y; and thus, in the stored state, the two ends of the flexible display screen 1 are inserted into the guide structure 4, and the two ends of the flexible display screen 1 can be limited by the guide structure 4.

[0140] In this case, refer to Fig.12 As shown, the portable mobile terminal has an unfolded state, in which the display surface 1a of the flexible display screen 1 is substantially parallel to the key surface 2a of the physical keyboard 2, and the flexible display screen 1 does not overlap with the physical keyboard 2; the flexible display screen 1 rotates so that the connecting structure 3 is substantially formed into a flat plate, the first connecting portion 31 and the second connecting portion 32 are substantially located in the same plane, and the display surface 1a of the flexible display screen 1 is substantially parallel to the key surface 2a of the physical keyboard 2 to form an unfolded state.

[0141] In the expanded state, refer to Fig.13As shown, the flexible display screen 1 and the physical keyboard 2 are arranged on opposite sides of the third direction Z of the connection structure 3, and 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 buckling inner side of the first connection part 31, and the flexible display screen 1 is connected to the buckling outer side of the first connection part 31. The buckling inner side is the side where the first connection part 31 and the second connection part 32 are close to each other after buckling, and the buckling outer side is the side where the first connection part 31 and the second connection part 32 are far from each other after buckling.

[0142] Reference Fig.13 As shown, the portable mobile terminal may further include a connectable and detachable structure 5. In the use state, the flexible display screen 1 is connected to the connection structure 3 via the connectable and detachable structure 5. In the storage state, the flexible display screen 1 is detached from the connection structure 3 via the connectable and detachable structure 5.

[0143] The connectable and detachable structure 5 may include an electromagnet 51 and an attraction portion 52. Specifically, the electromagnet 51 may be provided on the first connection portion 31. A portion of the first support plate 101 is the attraction portion 52 that can be attracted by the electromagnet 51. The attraction portion 52 is made of iron. When the electromagnet 51 is powered on, the electromagnet 51 is attracted to the attraction portion 52 of the first support plate 101, thereby fixing the flexible display screen 1 to the connection structure 3. When the electromagnet 51 loses power, the flexible display screen 1 is detached from the connection structure 3.

[0144] Of course, in some other exemplary embodiments of the present disclosure, an electromagnet may be provided on the first support plate 101, and a portion of the first connection portion 31 may be an attraction portion that can be attracted by the electromagnet. When the electromagnet is powered on, the electromagnet is attracted to the attraction portion of the first connection portion 31, thereby fixing the flexible display screen 1 to the connection structure 3. When the electromagnet loses power, the flexible display screen 1 is separated from the connection structure 3.

[0145] By pushing the flexible display screen 1, the flexible display screen can be pushed to the non-key surface 2b of the physical keyboard 2. The guide structure 4 can provide guidance for the movement of the flexible display screen 1, and can limit the flexible display screen 1 to a certain extent to prevent the flexible display screen 1 from being separated from the physical keyboard 2, which is conducive to subsequent folding.

[0146] Reference Fig.14 As shown, the length of the first connection portion 31 in the first direction X can be set to be longer, and the first connection portion 31 can include two side panels 311 , and the two side panels 311 are arranged on both sides of the first direction X of the flexible display screen 1 .

[0147] The connectable and detachable structure 5 may be a snap-fit ​​structure, which may include a connection hole 3111 provided on the side plate 311 of the first connection portion 31, and a mounting hole 1011 provided on the side wall of the first support plate 101. An elastic member 53 is fixed in the mounting hole 1011, and the elastic member 53 may be a coil spring, a rubber member, a plastic member, etc. One end of the elastic member 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 member 53, that is, one end of the pin 54 is fixed to the elastic member 53, and the opposite end surface of the pin 54 is set to a spherical surface. The pin 54 is clamped in the connection hole 3111 to fix the flexible display screen 1 to the connection structure 3. The flexible display screen 1 is pushed with force to make the pin 54 come out of the connection hole 3111, so that the flexible display screen 1 is detached from the connection structure 3.

[0148] The first connection portion 31 can be arranged into multiple sections along the first direction and connected by a hinge structure, so that the first connection portion 31 can be folded together with the physical keyboard 2 .

[0149] In this case, refer to Fig.15 As shown, in the storage state, the flexible display screen 1 is covered outside the physical keyboard 2. When it is necessary to store and carry, the flexible display screen 1 and the physical keyboard 2 are folded synchronously. Specifically, refer to Fig.12 As shown, 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 and detachable structure 5, the flexible display screen 1 is pushed so that the flexible display screen 1 is inserted into the guide structure 4, and the two keyboard folding parts 21b of the physical keyboard 2 and the two display folding parts 11b of the flexible display screen 1 are synchronously folded toward the key surface 2a of the physical keyboard 2, referring to Fig.15 As shown, the folded flexible display screen 1 and the physical keyboard 2 are almost completely integrated, which is further convenient to carry. Moreover, the display surface 1a of the flexible display screen 1 is arranged 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 inner side to avoid wear and tear on the display surface 1a; and avoid collision with the display surface; the key surface 2a is located on the inner side to avoid accidental touch of the key, and avoid collision between the protruding key and other structures, resulting in the key falling off.

[0162] Of course, in some other example embodiments of the present disclosure, the guide rail structure 6 may include only the first guide rail 61, then the three guide rail portions 6a are respectively the first guide bar 611, the second guide bar 612 and the third guide bar 613, and the hinge structure 6b may be provided with two, namely the first hinge structure 6b1 and the second hinge structure 6b2 mentioned above, and the specific structures of the first hinge structure 6b1 and the second hinge structure 6b2 are not repeated here.

[0163] In this case, refer to Fig. 20 As shown, in the storage state, the flexible display screen 1 is rolled up in the first roll 7, the physical keyboard 2 is wrapped in the guide rail structure 6, and the guide rail structure 6 is arranged adjacent to the non-key surface 2b of the physical keyboard 2. Fig.18 As shown, the flexible display screen 1 is rolled up in the first roll 7, referring to Fig.19 As shown, the guide rail structure 6 is then rotated to the key surface 2a of the physical keyboard 2, referring to Fig. 20 As shown, the two keyboard folding parts 21b of the physical keyboard 2 and the two guide rail parts 6a of the guide rail structure 6 on both sides are synchronously folded toward the key surface 2a of the physical keyboard 2, so that the folded guide rail structure 6 and the physical keyboard 2 are almost completely integrated, which is further convenient to carry. Moreover, when the guide rail part 6a of the guide rail structure 6 rotates, it drives the first reel 7 to rotate together, so that the first reel 7 is located between the two adjacent keyboard folding parts 21b. The key surface 2a is located on the inner side to avoid accidental touching of the keys and to avoid collision between the protruding keys and other structures, resulting in the keys falling off.

[0164] In this case, the number of connecting structures 3 between the physical keyboard 2 and the guide rail structure 6 can be three, with one connecting structure 3 being provided between each keyboard portion 21 and the guide rail structure 6 .

[0165] In some example embodiments of the present disclosure, reference is made to Figure 21-24 As shown, the flexible display screen 1 is stored in a roll-up manner, that is, the flexible display screen 1 can be rolled and deformed; the physical keyboard 2 is also stored in a roll-up manner, that is, the physical keyboard 2 can be rolled and deformed.

[0166] The portable mobile terminal may further include a guide rail structure 6, a first roller 7, a first scroll 72, a second roller 8 and a second scroll 82; the flexible display screen 1 is unfolded and stored by the guide rail structure 6, the first roller 7 and the first scroll 72. The specific structure of the guide rail structure 6, the first roller 7 and the first scroll 72 has been described in detail above, so it will not be repeated here.

[0167] A second opening portion 81 is provided on the second reel 8, and the second opening portion 81 extends along the axial direction of the second reel 8. The length of the second opening portion 81 is substantially the same as the width of the physical keyboard 2. The second reel 82 is rotatably connected to the second reel 8. Specifically, a second reel 82 is provided in the second reel 8, and the second reel 82 extends along the axial direction of the second reel 8. Both ends of the second reel 82 are rotatably connected to the second reel 8 through bearings.

[0168] In use, refer to Fig.21 As shown, one end of the physical keyboard 2 is connected to the second roll 8 through the second opening 81, and the rest of the physical keyboard 2 is unfolded outside the second roll 8; in the storage state, refer to Fig.24 As shown, the physical keyboard 2 is rolled up in the second reel 8 and rolled up on the second reel 82 . Moreover, the tail end of the physical keyboard 2 is left outside the second reel 8 to facilitate the unfolding of the physical keyboard 2 when in use. The tail end is the opposite end to one end connected to the second reel 82 .

[0169] The portable mobile terminal may further include a second drive mechanism 92, which may be a rotating motor having a drive shaft, which is fixedly connected to the second scroll 82. The forward rotation of the rotating motor drives the second scroll 82 to rotate, and the rotation of the second scroll 82 rolls the physical keyboard 2 onto the second scroll 82; the reverse rotation of the rotating motor drives the second scroll 82 to rotate, so that the physical keyboard 2 is unfolded outside the second scroll 8.

[0170] In this case, refer to Fig.24 As shown, in the storage state, the guide rail structure 6 is rolled up in the second reel 8 and wound on the second reel 82. The width of the second opening 81 on the second reel 8 can be set wider so that the guide rail structure 6 can extend into the second reel 8. When it is necessary to fold and carry, refer to Fig. 22 As shown, the flexible display screen 1 is rolled up in the first roll 7, referring to Fig.23 As shown, the guide rail structure 6 and the first reel 7 are then rotated together to the key surface 2a of the physical keyboard 2, so that the first reel 7 is arranged parallel to the second reel 8; Fig.24As shown, the physical keyboard 2 is rolled up into the second reel 8. Since the guide rail structure 6 fits against the key surface 2a of the physical keyboard 2, the physical keyboard 2 will drive the guide rail structure 6 to be rolled up together, so that most of the guide rail structure 6 is rolled up into the second reel 8, and the end of the guide rail structure 6 that is not rolled up is connected to the first reel 7, so that the first reel 7 and the second reel 8 are connected through the guide rail structure 6, which is further convenient for carrying.

[0171] The material of the guide rail structure 6 can be a memory alloy, or can be a material with good flexibility such as rubber and resin.

[0172] 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 shorter to facilitate the curling deformation of the physical keyboard 2 and the guide rail structure 6.
