[0002] The smart terminal with foldable screen includes a hinge and a flexible screen, and the opposite folded two parts of the flexible screen are hinged by the hinge to facilitate unfolding or folding the flexible screen.

[0003] In the process of conceiving and implementing the present application, the inventors have found that at least the following problems exist: In the foldable smart terminal, the flexible screen has a light-emitting side and a backlight side, and part of the backlight side is attached to the hinge. In the folding process, the light-emitting sides of the flexible screen move towards each other, and after folding is completed, the flexible screen is clamped between the hinges.

[0064] In the following description, the suffixes "module", "part" or "unit" used for components are merely intended for facilitating description of the present application, and they are not intended to limit the present application. Therefore, "module", "part" or "unit" can be mixedly used.

[0065] In the embodiment, if the fixed connection between the flexible screen and the hinge is not considered, the distance between the position of the flexible screen connected with the end of the hinge and the end of the hinge will gradually increase with the folding process, because the rotating radius of the hinge is greater than the rotating radius of the flexible screen. However, the flexible screen is actually fixedly attached to the hinge, so the flexible screen is gradually compressed with the folding process, which causes the flexible screen to be easily damaged.

[0066] The hinge device and the intelligent terminal provided in the embodiment can avoid the compression of the flexible screen in the folding process, thereby prolonging the service life of the flexible screen.

[0067] The principles and characteristics of the embodiments of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the embodiments of the present application, and are not used to limit the scope of the embodiments of the present application.

[0068] The intelligent terminal provided in the embodiment can include a flexible screen and a hinge device, and the hinge device is used to carry the flexible screen, and the flexible screen can be bent under the action of an external force.

[0069] Please refer to Figures 1-4 The hinge device in the embodiment can include a folding assembly 10 and a fixing member 20, the folding assembly 10 can include a swing arm mechanism 110 and a connecting assembly, and the connecting assembly has a carrying surface for carrying the flexible screen. The swing arm mechanism 110 can include a first movable member 111 and a second movable member 112, and the fixing member 20, the first movable member 111, the second movable member 112 and the connecting assembly are sequentially and end-to-end hingedly connected. Optionally, the second movable member 112 can rotate about a first rotation axis relative to the first movable member 111, and the connecting assembly can rotate about a second rotation axis relative to the second movable member 112, the second rotation axis is parallel to and does not coincide with the first rotation axis, and the distance between the second rotation axis and the fixing member 20 is greater than the distance between the first rotation axis and the fixing member 20.

[0070] Optionally, the hinge device has an unfolded state and a folded state, when the hinge device is in the unfolded state, the plane where the first rotation axis and the second rotation axis are located and the carrying surface have a first included angle, the first included angle is an acute angle, the projection of the first rotation axis and the second rotation axis on the carrying surface has a first distance, and the first distance is less than the distance between the first rotation axis and the second rotation axis.

[0071] When the hinge device is in the folded state, the plane in which the first rotation axis and the second rotation axis lie can be parallel to the bearing surface, the first rotation axis and the second rotation axis have a second distance between the projections on the bearing surface, and the second distance can be equal to the distance between the first rotation axis and the second rotation axis. Therefore, the second distance is greater than the first distance.

[0072] It should be noted that when the hinge device is in the unfolded state, the flexible screen is also in the unfolded state; when the hinge device is in the folded state, the flexible screen is also in the folded state. Regardless of whether the hinge device is in the unfolded state or the folded state, the bearing surface of the connecting assembly is always parallel to the extension plane of the corresponding flexible screen.

[0073] Optionally, when the hinge device is in the folded state, the plane in which the first rotation axis and the second rotation axis lie can have a second included angle with the bearing surface. The second included angle is also an acute angle, and the second included angle is smaller than the first included angle. The first rotation axis and the second rotation axis have a second distance between the projections on the bearing surface. The second distance is smaller than the distance between the first rotation axis and the second rotation axis, and the second distance is greater than the first distance.

[0074] During the process of changing from the unfolded state to the folded state of the hinge device, the included angle between the plane in which the first rotation axis and the second rotation axis lie and the bearing surface gradually decreases, so that the distance between the projections of the first rotation axis and the second rotation axis on the bearing surface gradually increases, thereby compensating for the length of the swing arm mechanism 110, avoiding compression of the flexible screen during folding, preventing the flexible screen from being damaged, and thereby prolonging the service life of the flexible screen.

[0075] Optionally, the folding assembly 10 can further include a synchronization mechanism 130. The synchronization mechanism 130 includes a third movable piece 131. The third movable piece 131 is hinged to the fixed piece 20 and can rotate about a third rotation axis relative to the fixed piece 20. The third rotation axis is parallel to and does not coincide with the first rotation axis. An end of the third movable piece 131 away from the third rotation axis is slidingly connected to the connecting assembly.

[0076] On the one hand, compared with connecting the fixed piece 20 and the connecting assembly only by the swing arm mechanism 110, the embodiment connects the fixed piece 20 and the connecting assembly by the swing arm mechanism 110 and the synchronization mechanism 130, thereby improving the connection strength between the folding assembly 10 and the fixed piece 20. On the other hand, the third movable piece 131 is slidingly connected to the connecting assembly to compensate for the length of the folding assembly 10, further avoiding compression of the flexible screen during folding, preventing the flexible screen from being damaged, and thereby prolonging the service life of the flexible screen.

[0077] Optionally, the connecting assembly can include a first connecting piece 121 and a second connecting piece 122, the first connecting piece 121 is in sliding connection with the third movable piece 131, the second connecting piece 122 can be in the form of a plate, the second connecting piece 122 is arranged on the side of the first connecting piece 121 facing the flexible screen, and the bearing surface is located on the side of the second connecting piece 122 away from the first connecting piece 121. The first connecting piece 121 and the second connecting piece 122 can be integrally formed to facilitate the assembly of the third movable piece 131 and the connecting assembly.

[0078] The flexible screen and the third movable piece 131 are in sliding connection through the first connecting piece 121 and the second connecting piece 122, so as to improve the synchronization between the flexible screen and the hinge device and avoid deformation or damage of the flexible screen.

[0079] Optionally, the connecting assembly can further include a third connecting piece 123, the second movable piece 112 is hinged to the third connecting piece 123, and the third connecting piece 123 is rotatable about a second rotation axis relative to the second movable piece 112, the second rotation axis is parallel to the first rotation axis, and the distance between the second rotation axis and the fixed piece 20 is greater than the distance between the first rotation axis and the fixed piece 20. The third connecting piece 123 is also in sliding connection with the third movable piece 131, and the third connecting piece 123 is fixedly connected with the second connecting piece 122. The second movable piece 112 and the third movable piece 131 are connected through the third connecting piece 123 to limit the degrees of freedom between the second movable piece 112 and the third movable piece 131 and improve the synchronization between the swing arm mechanism 110 and the synchronous mechanism 130, so that the flexible screen is more smooth during folding.

[0080] Optionally, in the implementation manner in which the folding assembly 10 includes the swing arm mechanism 110 and the synchronous mechanism 130, the folding assembly 10 can further include a fourth movable piece 140 connected between the swing arm mechanism 110 and the synchronous mechanism 130. Optionally, the fourth movable piece 140 can be connected between the second movable piece 112 and the third movable piece 131, or the fourth movable piece 140 can be connected between the first movable piece 111 and the third movable piece 131.

[0081] Optionally, the fourth movable piece 140 is connected between the swing arm mechanism 110 and the synchronous mechanism 130 to improve the synchronization between the swing arm mechanism 110 and the synchronous mechanism 130, so that the flexible screen is more smooth during folding.

[0082] In some embodiments, continuing to refer to Figure 2 and Figure 4In the implementation where the fourth movable member 140 is connected between the second movable member 112 and the third movable member 131, one end of the fourth movable member 140 close to the fixed member 20 is hinged to the second movable member 112, and the fourth movable member 140 can rotate about the first rotation axis relative to the second movable member 112. The other end of the fourth movable member 140 away from the fixed member 20 is hinged to the third movable member 131, and the fourth movable member 140 can rotate about the fourth rotation axis relative to the third movable member 131, and the fourth rotation axis is parallel to the first rotation axis.

[0083] The fourth movable member 140 is connected between the second movable member 112 and the third movable member 131, so that the rotation of the third movable member 131 relative to the fixed member 20 is limited by the rotation of the second movable member 112 relative to the first movable member 111, thereby improving the synchronization between the third movable member 131 and the swing arm mechanism 110, and making the flexible screen fold more smoothly.

[0084] In some embodiments, referring to Figure 5 In the implementation where the fourth movable member 140 is connected between the first movable member 111 and the third movable member 131, the fourth movable member 140 is fixedly connected to the third movable member 131, and the fourth movable member 140 has a sliding channel, and the first movable member 111 has a sliding column 1111, the axis of the sliding column 1111 is parallel to the first rotation axis, and the sliding column 1111 is slidably arranged in the sliding channel. When the first movable member 111 and the third movable member 131 rotate relative to the fixed member 20 respectively, the sliding column 1111 of the first movable member 111 is slidably arranged in the sliding channel, so that the rotation of the third movable member 131 relative to the fixed member 20 is limited by the rotation of the second movable member 112 relative to the first movable member 111, thereby improving the synchronization between the third movable member 131 and the swing arm mechanism 110, and making the flexible screen fold more smoothly.

[0085] Optionally, the above-mentioned connecting assembly can be two, and the two connecting assemblies are arranged on both sides of the fixed member 20, and each connecting assembly is connected with at least one folding assembly 10 to adapt to the smart terminal where both sides of the flexible screen can be folded. Optionally, the number of folding assemblies 10 corresponding to each connecting assembly can be equal or not equal, and the interval between adjacent two folding assemblies 10 on the same side of the fixed member 20 can be equal or not equal, as long as the folding assemblies 10 can be connected on both sides of the fixed member.

[0086] Optionally, one side of the fixing member 20 can be provided with two folding assemblies 10, and the two folding assemblies 10 can be arranged at intervals along the extending direction of the fixing member 20; the other side of the fixing member 20 can be provided with one folding assembly 10, which can be arranged at any position on the other side of the fixing member 20, i.e., the folding assembly 10 can be symmetrical to one of the two folding assemblies 10 on one side of the fixing member 20, or can correspond to the position between the two folding assemblies 10 on one side of the fixing member 20.

[0087] Optionally, the number of folding assemblies 10 on both sides of the fixing member 20 can be equal, and the folding assemblies 10 on both sides of the fixing member 20 can be symmetrical about the axis of the fixing member 20, so that the flexible screen is more uniform in stress during folding or unfolding, and the flexible screen is less likely to be damaged.

[0088] Optionally, one end of the folding assembly 10 connected with the fixing member 20 can be provided with a connecting column 1311, the axis of the connecting column 1311 can be parallel to and not coincide with the first rotation axis, and the outer circumferential side of the connecting column 1311 can be provided with a transmission tooth, the transmission tooth corresponding to the connecting assembly on one side of the fixing member 20 meshes with the transmission tooth corresponding to the connecting assembly on the other side of the fixing member 20, so that the angles of the folding assemblies 10 on both sides of the fixing member 20 relative to the fixing member 20 during unfolding or folding are always equal, i.e., the folding assemblies 10 on both sides of the fixing member 20 are always symmetrically distributed on both sides of the fixing member 20, so that the folding assemblies 10 on both sides of the fixing member 20 can rotate synchronously, and then the two sides of the flexible screen can rotate synchronously.

[0089] In the implementation mode in which the hinge device includes the swing arm mechanism 110 and the synchronization mechanism 130, the connecting column 1311 can be arranged on the swing arm mechanism 110 and / or the synchronization mechanism 130, and optionally, the connecting column 1311 can be arranged on the first movable member 111 and / or the third movable member 131.

[0090] Optionally, referring to Figure 6 and Figure 7 , a first gear 211 and a second gear 212 can also be arranged between the two connecting columns 1311, the first gear 211 and the second gear 212 are rotatably connected with the fixing member 20, and the rotation axes of the first gear 211 and the second gear 212 are parallel to the first rotation axis, the first gear 211 and the second gear 212 are meshed, the transmission tooth on one connecting column 1311 meshes with the first gear 211, and the transmission tooth on the other connecting column 1311 meshes with the second gear 212.

[0091] The two connecting columns 1311 are synchronously rotated by the first gear 211 and the second gear 212 engaged with each other, so that the two connecting columns 1311 in each folding assembly 10 can be arranged at intervals to increase the distance between the two connecting columns 1311 in each folding assembly 10, avoiding that the distance between the connecting columns 1311 is too close to compress the flexible screen when the hinge device is in the folded state.

[0092] In some embodiments, the folding assembly 10 and the fixed part 20 can be connected by a fixing rod 220, the axis of the fixing rod 220 is parallel to the first rotation axis, the fixing rod 220 is arranged in the folding assembly 10, and the two ends of the fixing rod 220 are fixedly connected to the fixed part 20. Alternatively, one end of the extension direction of the fixing rod 220 can be arranged in the fixed part 20, and the other end of the extension direction of the fixing rod 220 can be welded to the fixed part 20, so as to avoid that the folding assembly 10 moves along the extension direction of the fixed part 20 and / or the direction perpendicular to the axis of the fixing rod 220 during folding, thereby avoiding the problem of local bulging of the flexible screen.

[0093] After the fixing rod 220 is arranged in the connecting column 1311 and one end of the extension direction of the fixing rod 220 is arranged in the fixed part 20 when the folding assembly 10 is installed, the other end of the extension direction of the fixing rod 220 is welded to the fixed part 20, so as to improve the connection strength between the fixing rod 220 and the fixed part 20, and prevent the fixing rod 220 from being separated from the fixed part 20.

[0094] Alternatively, in each folding assembly 10, the connecting column 1311 can include a first connecting column 1312 and a second connecting column 1313 arranged at intervals. The fixing rod 220 can further be sleeved with a gear limiting part 221 located between the first connecting column 1312 and the second connecting column 1313.

[0095] Alternatively, the two gear limiting parts 221 are integrally formed, the gear limiting part 221 is provided with a first fixing hole and a second fixing hole, the axes of the first fixing hole and the second fixing hole are parallel to the first rotation axis; the first gear 211 is arranged in the first rotation shaft and rotates with the first rotation shaft, one end of the first rotation shaft is arranged in the fixed part 20, and the other end of the first rotation shaft is arranged in the first fixing hole; the second gear 212 is arranged in the second rotation shaft and rotates with the second rotation shaft, one end of the second rotation shaft is arranged in the fixed part 20, and the other end of the second rotation shaft is arranged in the second fixing hole.

[0096] Compared with directly fixing the first rotating shaft and the second rotating shaft to the fixing piece 20, the one end of the first rotating shaft and the second rotating shaft is arranged on the gear limiting piece 221 in the embodiment, so as to facilitate the installation of the first gear 211 and the second gear 212. When the folding assembly 10, the first gear 211 and the second gear 212 are installed, the one end of the first rotating shaft and the second rotating shaft is arranged in the fixing piece 20 first, then the fixing rod 220 is arranged in the first connecting column 1312, the gear limiting piece 221 and the second connecting column 1313 in sequence, then the end of the fixing rod 220 close to the second connecting column 1313 is arranged in the connecting hole on the fixing piece 20, at the same time, the other end of the first rotating shaft and the second rotating shaft is arranged in the first fixing hole and the second fixing hole respectively, so as to fix the first gear 211 and the second gear 212, finally the end of the fixing rod 220 away from the second connecting column 1313 is welded with the fixing piece 20.

[0097] Optionally, in the implementation mode in which the connecting column 1311 is arranged on the synchronous mechanism 130 (the third movable piece 131), the fixing rod 220 can further be sleeved with the first elastic piece 222. The first elastic piece 222 can be a spring, a rubber ring or other elastic component. The first elastic piece 222 is located at the end of the synchronous mechanism 130 away from the swing arm mechanism 110, and the first elastic piece 222 abuts against the connecting column 1311. The first elastic piece 222 has a certain elasticity. During the unfolding or folding process of the hinge device, the first elastic piece 222 can make the synchronous mechanism 130 (or the third movable piece 131) have a certain movement space in the direction along the axis of the fixing rod 220, so as to avoid the problem of misalignment of the flexible screen during use.

[0098] Optionally, the fixing rod 220 can further be sleeved with the buffer piece 223. The buffer piece 223 is located between the first elastic piece 222 and the connecting column 1311. The buffer piece 223 can be a rubber piece or a silica gel piece. The buffer piece 223 can buffer the elastic force between the first elastic piece 222 and the synchronous mechanism 130 (or the third movable piece 131), so that the synchronous mechanism 130 (or the third movable piece 131) moves slowly in the direction along the axis of the fixing rod 220, so as to improve the stability of the hinge device during the unfolding or folding process.

[0099] Optionally, the buffer pieces 223 on the two fixing rods 220 can be integrally formed. On the one hand, the synchronism of the two buffer pieces 223 can be improved, and on the other hand, the installation of the buffer pieces 223 can be facilitated.

[0100] Optionally, the side of the buffer 223 away from the first movable part 111 can be provided with a first limiting post, the axis of the first limiting post is parallel to the axis of the fixed rod 220, and the first limiting post can be located between the two fixed rods 220 in each folding assembly 10. The fixed part 20 can be provided with a second limiting post, the axis of the second limiting post is collinear with the axis of the first limiting post, the second limiting post is opposite to the first limiting post, and the second limiting post and the first limiting post have a preset gap in the axial direction. When the synchronous mechanism 130 and the buffer 223 move towards the second limiting post to abut the first limiting post and the second limiting post, the second limiting post can block the buffer 223 to avoid the synchronous mechanism 130 continuing to move away from the swing arm mechanism 110, and to avoid the flexible screen being locally bulged due to excessive displacement.

[0101] Optionally, the first limiting post and the second limiting post can be sleeved with a second elastic member 224, the second elastic member 224 can be a spring, a rubber ring or other elastic component, one end of the second elastic member 224 along the axial direction of the first limiting post abuts against the buffer 223, and the other end abuts against the fixed part 20. The second elastic member 224 can make the buffer 223 have a certain movement space relative to the fixed part 20 along the axial direction of the fixed rod 220, so as to indirectly buffer the synchronous mechanism 130 (or the third movable part 131), and further avoid the flexible screen from being twisted and deformed.

[0102] In the embodiment of the present application, the connecting post 1311, the gear limiting part 221, the buffer 223 and the first elastic member 222 are all arranged on the fixed rod 220, and the fixed rod 220 is welded to the fixed part 20, which greatly reduces the cumulative tolerance of the hinge device in manufacturing and assembly, and avoids the problem that the flexible screen is dislocated in use.

[0103] The hinge device can further include a decoration part 30, the decoration part 30 covers the side of the fixed part 20 away from the flexible screen, and the decoration part 30 can shield the fixed part 20 to improve the decoration effect of the hinge device.

[0104] The decoration part 30 can be detachably connected to the fixed part 20. For example, the decoration part 30 and the fixed part 20 can be connected by fastening bolts. When the decoration part 30 and the fixed part 20 are installed, the fastening bolts pass through the fixed part 20 and are connected to the decoration part 30, so that the fastening bolts cannot be observed from the outside of the decoration part 30, and the decoration effect of the hinge device is improved.

[0105] Of course, the decoration part 30 and the fixed part 20 can also be connected by clamping. The clamping structure can be the clamping structure between two components in related technologies, which will not be described here.

[0106] In the process of conceiving and implementing the present application, the inventors have found that there is also the problem that when the flexible screen is folded to the folded state, the flexible screen will not be squeezed. If the flexible screen continues to be folded inward from the folded state, the flexible screen will be squeezed, and if the degree of squeezing is too large, it will cause the flexible screen to be damaged. In the related art, there is a lack of a limiting mechanism between the flexible screen and the hinge device, which makes it difficult for the user to know whether the flexible screen has reached the folded state, and the flexible screen is easily over-folded, which reduces the service life of the flexible screen.

[0107] The hinge device and the intelligent terminal provided by the embodiments of the present application are provided. By arranging a limiting mechanism between the folding assembly 10 and the fixing member 20, the limiting mechanism is configured to control the rotation angle of the folding assembly to prevent the folding assembly 10 from continuing to be folded inward from the folded state, thereby avoiding over-folding of the flexible screen connected to the folding assembly 10, preventing the flexible screen from being damaged, and prolonging the service life of the flexible screen.

[0108] The principles and characteristics of the embodiments of the present application are described below in conjunction with the accompanying drawings. The examples are only used to explain the embodiments of the present application and are not intended to limit the scope of the embodiments of the present application.

[0109] The intelligent terminal provided by the embodiments of the present application includes a flexible screen and a hinge device, and the hinge device is used to carry the flexible screen. The flexible screen can be bent under the action of an external force.

[0110] Reference Figure 8 and Figure 9 The hinge device includes a folding assembly 10 and a fixing member 20. The folding assembly 10 is hinged to the fixing member 20. A limiting mechanism is arranged between the folding assembly 10 and the fixing member 20. The limiting mechanism is configured to control the rotation angle of the folding assembly to prevent the folding assembly 10 from continuing to be folded inward from the folded state, so that the folding assembly 10 and the flexible screen cannot continue to be folded inward after being folded to the folded state, thereby avoiding over-folding of the flexible screen, preventing the flexible screen from being damaged, and improving the service life of the flexible screen.

[0111] Optionally, the folding assembly 10 can include the swing arm mechanism 110 and the synchronization mechanism 130 in the above-mentioned embodiments. The limiting mechanism can be arranged between the swing arm mechanism 110 (the first movable member 111) and the fixing member 20, and / or between the synchronization mechanism 130 (the third movable member 131) and the fixing member 20.

[0112] Optionally, the limiting mechanism can include a first limiting member and a second limiting member. The first limiting member is arranged on the folding assembly 10, and the second limiting member is arranged on the fixing member 20. The first limiting member can slide relative to the second limiting member along a preset direction. The preset direction can be the same as the folding direction of the folding assembly 10. When the hinge device is in the folded state, the first limiting member and the second limiting member abut to block the folding assembly 10 from continuing to be folded inward.

[0113] In some embodiments, the first limiting member can have an arc-shaped slide 230, and the second limiting member can include a limiting block 1314 that is slidably arranged in the arc-shaped slide 230.

[0114] In some embodiments, the first limiting member can include a limiting block 1314, and the second limiting member can have an arc-shaped slide 230 in which the limiting block 1314 is slidably arranged.

[0115] Optionally, the following is described by taking the limiting mechanism arranged between the synchronous mechanism 130 and the fixed member 20 as an example.

[0116] Reference is made to Figure 10 and Figure 11 During the rotation of the folding assembly 10 relative to the fixed member 20 about the rotation axis, the limiting block 1314 slides in the arc-shaped slide 230 in a preset direction, and when the folding assembly 10 is rotated to the folded state, the limiting block 1314 abuts against the end of the arc-shaped slide 230, so that the limiting block 1314 cannot continue to slide in the preset direction relative to the fixed member 20, and thus the folding assembly 10 and the flexible screen cannot continue to be folded inward after being in the folded state.

[0117] In some embodiments, the first limiting member (the limiting block 1314) has a first stop portion at one end of the first limiting member in the preset direction, and the second limiting member (the arc-shaped slide 230) has a third stop portion at one end of the second limiting member in the preset direction, and the first stop portion and the third stop portion abut against each other when the hinge device is in the folded state.

[0118] In some implementations, the first stop portion can include a first stop surface 1315, and the third stop portion can include a third stop surface 231, and the first stop surface 1315 and the third stop surface 231 abut against each other when the hinge device is in the folded state.

[0119] In other implementations, the first stop portion can include a first stop protrusion, and the third stop portion can include a third stop protrusion, and the first stop protrusion and the third stop protrusion abut against each other when the hinge device is in the folded state.

[0120] Optionally, the first limiting member (the limiting block 1314) can further have a second stop portion at an end of the first limiting member away from the first stop portion, and the second limiting member (the arc-shaped slide 230) can further have a fourth stop portion at an end of the second limiting member away from the third stop portion, and the second stop portion and the fourth stop portion abut against each other when the hinge device is in the unfolded state, so that the folding assembly 10 and the flexible screen cannot continue to be unfolded outward when the hinge device is in the unfolded state, and the flexible screen is prevented from being stretched, thereby avoiding damage to the flexible screen.

[0121] In some implementations, the second stop portion includes a second stop surface 1316, and the fourth stop portion includes a fourth stop surface 232, and the second stop surface 1316 and the fourth stop surface 232 are in contact when the hinge device is in the unfolded state.

[0122] In some implementations, the second stop portion includes a second stop protrusion, and the fourth stop portion includes a fourth stop protrusion, and the second stop protrusion and the fourth stop protrusion are in abutment when the hinge device is in the unfolded state.

[0123] Optionally, in the implementations in which the first stop portion includes a first stop surface 1315, the second stop portion includes a second stop surface 1316, the third stop portion includes a third stop surface 231, and the fourth stop portion includes a fourth stop surface 232, the maximum value of the included angle between the second stop surface 1316 and the fourth stop surface 232 is 90°, so that the folding assembly 10 is folded from the unfolded state to the folded state, and the folding assembly 10 rotates by 90 degrees.

[0124] Optionally, the following describes an example in which the limiting mechanism is arranged between the swing arm mechanism 110 and the fixed member 20.

[0125] Reference is made to Figure 12 and Figure 13 , one end of the edge of the arc-shaped slide channel 230 close to the fixed member 20 can have a stop channel 240, the width of the stop channel 240 in the radial direction gradually decreases in the direction away from the arc-shaped slide channel 230; the limiting block 1314 has a clamping end, and when the hinge device is in the folded state, the clamping end is inserted into the stop channel 240, so that after the hinge device is in the folded state, the limiting block 1314 cannot continue to slide in the preset direction relative to the fixed member 20, so that the folding assembly 10 and the flexible screen cannot continue to fold inward after being in the folded state.

[0126] Optionally, the fixed member 20 can include a first fixed block 251 and a second fixed block 252 connected to each other, and the arc-shaped slide channel and the stop channel are formed between the first fixed block 251 and the second fixed block 252.

[0127] The first fixed block 251 can be closer to the flexible screen than the second fixed block 252, and the side of the first fixed block 251 facing the second fixed block 252 can be provided with a fixed pin, and the second fixed block 252 can be provided with a positioning hole, and the positioning pin is inserted into the positioning hole, and the end of the positioning pin can be welded with the second fixed block 252, so as to improve the connection strength between the first fixed block 251 and the second fixed block 252.

[0128] Optionally, the positioning pin on the first fixed block 251 can be at least one, and the positioning hole on the second fixed block 252 can also be at least one. After the positioning pin is inserted into the corresponding positioning hole, the end of the positioning pin is welded with the second fixed block 252, so as to fix the first movable part 111 between the first fixed block 251 and the second fixed block 252.
