The display module 300 can be folded when the first housing 101 and the second housing 102 are folded.

[0040] It should be noted that the terms "first", "second" and the like in the present application are used only to describe the purpose and are not to be construed as indicating or implying relative importance or a specific number of the technical features indicated. Therefore, the features defined with "first", "second" and the like can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0041] It can be understood that the names of "first shell", "second shell" and "shell" can be converted to each other, for example, "first shell" can also be called "second shell".

[0042] Specifically, please refer to Figure 3 and Figure 4 , Figure 4 is Figure 3 the exploded view of the shell.

[0043] The shell 100 can be two, for example, a first shell 101 and a second shell 102. Each shell 100 can include a shell body 10 and a connecting piece 20. The shell body 10 is used to carry the display module 300, and can also be used to mount electronic components such as circuit boards, batteries, etc. The connecting piece 20 is mounted on the shell body 10 and used to connect with the folding assembly 200 to realize the connection between the shell 100 and the folding assembly 200.

[0044] Specifically, please refer to Figure 4 The shell body 10 can include a bottom plate 11, a side wall 12 and a fixed plate 13. The side wall 12 can be arranged at the edge of the bottom plate 11, that is, the side wall 12 can be arranged around the edge of the bottom plate 11. So that the bottom plate 11 and the side wall 12 form a receiving space for accommodating electronic components such as cameras, circuit boards, batteries, display modules 300, etc. The fixed plate 13 is arranged opposite to the bottom plate 11 and connected and fixed with the side wall 12. That is, the side wall 12 is arranged around the four sides of the fixed plate 13 and fixed with the fixed plate 13 to form a middle frame. The fixed plate 13 can divide the receiving space into two, forming a first receiving space and a second receiving space. The first receiving space is located between the bottom plate 11 and the fixed plate 13 and is used to accommodate electronic components such as cameras, circuit boards, batteries, etc. The second receiving space is located on the side of the fixed plate 13 away from the bottom plate 11 and is used to accommodate the display module 300.

[0045] Please refer to Figure 4The bottom plate 11 can be a plate structure, which can be rectangular or rounded rectangular, etc., which can be formed of plastic, glass, ceramic, fiber composite material, metal (e.g., stainless steel, aluminum, etc.), or other suitable material or combination of these materials. In some cases, a portion of the bottom plate 11 can be formed of a dielectric or other low-conductivity material. In other cases, the bottom plate 11 or at least some structures constituting the bottom plate 11 can be formed of a metal element.

[0046] The bottom plate 11 is provided with a mounting portion 14 for mounting the connecting member 20. The mounting portion 14 can be multiple. For example Figure 4 In an embodiment, the mounting portion 14 is two, which are respectively a first mounting portion 141 and a second mounting portion 142. The first mounting portion 141 and the second mounting portion 142 are respectively provided on one side of the bottom plate 11. The first mounting portion 141 and the second mounting portion 142 are respectively arranged close to the side walls 12 on both sides.

[0047] The mounting portion 14 is a hole arranged inwardly recessed from the bottom plate 11, which is used for plug-in fixing with the connecting member 20. It can also be fixed with the connecting member 20 with glue.

[0048] The side wall 12 is arranged around the edge of the bottom plate 11 and extends to the same side of the bottom plate 11. The side wall 12 is broken at the side of the bottom plate 11 where the mounting portion 14 is arranged to form an opening to accommodate the folding assembly 200. That is, the side wall 12 is arranged around three edges of the bottom plate 11, and the mounting portion 14 is arranged on the remaining one edge without the side wall 12 to form an opening.

[0049] The wall thickness of the side wall 12 on both sides of the opening is smaller than that of other positions to accommodate the folding assembly 200. Understandably, the opening can be more than one, and can be two or three. For example Figure 4 In an embodiment, the side wall 12 can also be arranged around the opposite two edges of the bottom plate 11, and each of the remaining two edges forms an opening. Of course, the side wall 12 can also be arranged around the adjacent two edges of the bottom plate 11, and each of the remaining two edges forms an opening.

[0050] In an embodiment, the bottom plate 11 and the side wall 12 are an integral structure, and the side wall 12 is made of the same material as the bottom plate 11.

[0051] In an embodiment, please refer to Figure 4 The side wall 12 and the base plate 511 are an integral structure,

[0052] The base plate 511 can be made of the same material as the side wall 12. In an embodiment, the base plate 511 does not cover the bottom plate 11 at the opening to accommodate the folding assembly 200, so that part of the structure of the folding assembly 200 is placed on the bottom plate 11.

[0053] Please refer to Figure 4 and Figure 5, Figure 5 is Figure 4 a perspective view of the connecting arm shown in the housing.

[0054] The connecting member 20 is used to connect with the folding assembly 200. The connecting member 20 can be multiple, for example, the connecting member 20 can be 2, which are respectively a first connecting member 201 and a second connecting member 202. The first connecting member 201 is installed on the mounting portion 14, for example, the first mounting portion 141. The second connecting member 202 is installed on the mounting portion 14, for example, the second mounting portion 142.

[0055] Specifically, the connecting member 20 can include a connecting member body 21 and a connecting arm 22. The connecting member body 21 is used to be installed on the mounting portion 14, for example, the first mounting portion 141 or the second mounting portion 142. The connecting arm 22 is provided at the opening of the connecting member body 21 and extends outwardly of the opening, which is used to be slidingly connected with the folding assembly 200.

[0056] Please refer to Figure 6 , Figure 6 is Figure 3 a perspective view of the folding assembly shown in the housing.

[0057] The folding assembly 200 can include a support plate 30 (for example, a first support plate 301 and a second support plate 302), a support frame 40, a rotating shaft module 50 (for example, a first rotating shaft module 501 and a second rotating shaft module 502). Specifically, the support frame 40 is arranged between two adjacent housings 100, for example, the support frame 40 is arranged between the first housing 101 and the second housing 102. The first rotating shaft module 501 and the second rotating shaft module 502 in the rotating shaft module 50 are respectively located at both ends of the support frame 40 and are respectively fixedly connected with the support frame 40. The rotating shaft module 50 is arranged between two adjacent housings 100 and is respectively connected with two adjacent housings 100, so that two adjacent housings 100 can be folded when the rotating shaft module 50 rotates. For example, the first rotating shaft module 501 and the second rotating shaft module 502 can both connect the first housing 101 and the second housing 102 together. The first support plate 301 and the second support plate 302 in the support plate 30 are symmetrically arranged and located on opposite sides of the support frame 40. The first support plate 301 is located between the first rotating shaft module 501 and the second rotating shaft module 502 and is rotatably connected with the first housing 101. The first support plate 301 is also rotatably connected with the first rotating shaft module 501 and the second rotating shaft module 502, respectively. The second support plate 302 is located between the first rotating shaft module 501 and the second rotating shaft module 502 and is rotatably connected with the second housing 102, respectively. The second support plate 302 is also rotatably connected with the first rotating shaft module 501 and the second rotating shaft module 502, respectively. The first support plate 301 and the second support plate 302 can be carried on the support frame 40 and used for carrying the display module 300. The first support plate 301 and the second support plate 302 and the display module 300 are fixed together and used for protecting the display module 300 to avoid the display module 300 from being damaged when the folding assembly 200 is folded.

[0058] Please refer to Figure 7 , Figure 7 is Figure 6 the perspective view of the support plate in the folding assembly shown in FIG. 1.

[0059] The support plate 30 can include a plurality of. For example, the support plate 30 can include two, which are the first support plate 301 and the second support plate 302. The first support plate 301 and the second support plate 302 are symmetrically arranged and located on both sides of the support frame 40, respectively, and are used for being bonded with the display module 300 together, for carrying the display module 300 during the folding or unfolding of the housing 100 assembly 100, so that the display module 300 can be bent and folded, and the surface of the display module 300 tends to be flat when unfolded.

[0060] Specifically, the supporting plate 30 can include a connecting plate 31. The connecting plate 31 can be a strip-shaped plate structure, which is used to be fixedly bonded with the display module 300. The connecting plate 31 is provided with connecting portions, such as a first connecting portion 311 and a second connecting portion 312, at both ends of one side edge, respectively, which are rotatably connected with the first mounting portion 141 and the second mounting portion 142, respectively, so as to realize the relative rotation between the supporting plate 30 and the connecting member 20.

[0061] The connecting plate 31 is provided with connecting portions, such as a third connecting portion 313 and a fourth connecting portion 314, at the side away from the first connecting portion 311 and the second connecting portion 312, which are used to be rotatably connected with the rotating shaft module 50, respectively. For example, the third connecting portion 313 is used to be rotatably connected with the first rotating shaft module 501. For example, the fourth connecting portion 314 is used to be rotatably connected with the second rotating shaft module 502.

[0062] Please refer to Figure 8 , Figure 8 is a perspective view of the supporting frame in the folding assembly shown in Figure 6 .

[0063] The supporting frame 40 can include a main supporting plate 41 and side wall plates 42 (for example, a first side wall plate 421, a second side wall plate 422, a third side wall plate 423 and a fourth side wall plate 424). The side wall plates 42, for example, the first side wall plate 421, the second side wall plate 422, the third side wall plate 423 and the fourth side wall plate 424, are sequentially connected and arranged around the main supporting plate 41 to form a containing space for containing the rotating shaft module 50.

[0064] The main supporting plate 41 is a strip-shaped structure, which can be partially disposed in the containing space in the first housing 101 from the opening and partially disposed in the containing space in the second housing 102 from the opening. The main supporting plate 41 can be provided with fixing portions 410 (for example, a first fixing portion 410a and a second fixing portion 410b), the first fixing portion 410a is arranged at one end of the main supporting plate 41 for mounting and fixing the first rotating shaft module 501, and the second fixing portion 410b is arranged at the other end of the main supporting plate 41 for mounting and fixing the second rotating shaft module 502.

[0065] Please refer to Figure 9 , Figure 10 and Figure 11 , Figure 9 is a perspective view of the folding module in the unfolded state of the folding assembly shown in Figure 6 , Figure 10 is a perspective view of the folding module in the folded state shown in Figure 9 , Figure 11 is an exploded view of the folding module shown in Figure 9 .

[0066] The rotating shaft module 50 can include a base 51, two rotating arms 52 (e.g., a first rotating arm 520a and a second rotating arm 520b) and a limiting piece 53. The two rotating arms 52 are respectively rotatably connected to the base 51 on different and parallel rotating shafts. The limiting piece 53 is fixedly connected to the base 51 and is used to prevent the first rotating arm 520a and / or the second rotating arm 520b from being separated from the base 51, so as to avoid that any rotating arm 52 is separated from the base 51 in the folded state of the whole electronic device 1000.

[0067] Please refer to Figure 12 , Figure 12 is Figure 11 a perspective view of the base in an embodiment of the folding module.

[0068] Optionally, the base 51 can include a base plate 511, a first base 512 and a mounting plate 513. The base plate 511 and the mounting plate 513 are respectively located on the opposite surfaces of the first base 512. The base plate 511 and the mounting plate 513 are respectively located on different and parallel planes and are fixedly connected to the first base 512. The base plate 511 is provided with a fixing hole 5110. A fixing piece such as a screw is arranged in the fixing hole 5110 and the fixing part 410, so as to realize the fixed connection with the main support plate 41 and the support frame 40. Specifically, the fixing hole 5110 includes a first fixing hole 5110a arranged on the base plate 511 of the first rotating shaft module 501. The first fixing hole 5110a corresponds to the first fixing part 410a, so as to realize the fixed connection between the first rotating shaft module 501 and the support frame 40. The fixing hole 5110 further includes a second fixing hole 5110b arranged on the base plate 511 of the second rotating shaft module 502. The second fixing hole 5110b corresponds to the second fixing part 410b, so as to realize the fixed connection between the second rotating shaft module 502 and the support frame 40.

[0069] Please refer to Figure 9 to Figure 12 The first base 512 can include a first surface 5120 away from the base plate 511. The mounting plate 513 can include a second surface 5130 parallel to the first surface 5120. The first surface 5120 and the second surface 5130 are arranged in a stepped manner, that is, the base 51 includes the first surface 5120 and the second surface 5130 arranged in a stepped manner. The limiting piece 53 is fixed to the second surface 5130. The side of the limiting piece 53 away from the second surface 5130 is flush with or slightly lower than the first surface 5120, so as to avoid that the display module 300 is uneven when the display module 300 is attached to the rotating shaft module 50, which affects the touch feeling of the display module 300.

[0070] Optionally, the first base 512 is provided with two first pivot grooves 5121 (for example, a first sliding groove 5121a and a second sliding groove 5121b) arranged adjacently on one side surface of the substrate 511, and two ends of each first pivot groove 5121 are connected to the first surface 5120, so as to facilitate the first rotating arm 520a and the second rotating arm 520b to be inserted into or at least partially out of the first pivot groove 5121. The first rotating arm 520a is capable of being accommodated and slidingly connected in the first sliding groove 5121a, and the second rotating arm 520b is capable of being accommodated and slidingly connected in the second sliding groove 5121b, so that the first rotating arm 520a and the second rotating arm 520b are capable of moving relative to the base 51. In this way, the size of the first rotating arm 520a and the second rotating arm 520b along the rotating shaft direction can be reduced, and the space utilization inside the electronic device 1000 can be improved.

[0071] Further, the first pivot groove 5121 is in a circular arc shape, that is, the first sliding groove 5121a and the second sliding groove 5121b are in a circular arc shape, and the first rotating arm 520a and the second rotating arm 520b are capable of sliding along the first sliding groove 5121a and the second sliding groove 5121b, so that the first rotating arm 520a and the second rotating arm 520b are capable of rotating relative to the base 51. It can be understood that, when the ends of the first rotating arm 520a and the second rotating arm 520b away from the base 51 are close to each other (as shown in FIG. 12A), the electronic device 1000 is in a folded state, and when the ends of the first rotating arm 520a and the second rotating arm 520b away from the base 51 are away from each other and are located in substantially the same plane (as shown in FIG. 12B), the electronic device 1000 is in an unfolded state. Figure 11 Figure 10 Further, the first pivot groove 5121 is in a circular arc shape, that is, the first sliding groove 5121a and the second sliding groove 5121b are in a circular arc shape, and the first rotating arm 520a and the second rotating arm 520b are capable of sliding along the first sliding groove 5121a and the second sliding groove 5121b, so that the first rotating arm 520a and the second rotating arm 520b are capable of rotating relative to the base 51. It can be understood that, when the ends of the first rotating arm 520a and the second rotating arm 520b away from the base 51 are close to each other (as shown in FIG. 12A), the electronic device 1000 is in a folded state, and when the ends of the first rotating arm 520a and the second rotating arm 520b away from the base 51 are away from each other and are located in substantially the same plane (as shown in FIG. 12B), the electronic device 1000 is in an unfolded state.

[0072] Optionally, the first base 512 is further provided with two limiting grooves 5122 on the first surface 5120, for example, a first limiting groove 5122a and a second limiting groove 5122b, the first limiting groove 5122a is in communication with the first sliding groove 5121a, and the second limiting groove 5122b is in communication with the second sliding groove 5121b. The first limiting groove 5122a is located at one end of the first sliding groove 5121a away from the second sliding groove 5121b, and the second limiting groove 5122b is located at one end of the second sliding groove 5121b away from the first sliding groove 5121a. The limiting member 53 is respectively clamped and accommodated in the first limiting groove 5122a and the second limiting groove 5122b, and is used to block the first rotating arm 520a and the second rotating arm 520b from being separated from the base 51 in the folded state of the electronic device 1000.

[0073] Please refer to Figure 9 and Figure 10 ​Specifically, the first limiting groove 5122a is communicated with one end of the first sliding groove 5121a away from the second sliding groove 5121b, and the second limiting groove 5122b is communicated with one end of the second sliding groove 5121b away from the first sliding groove 5121a. Understandably, when the first rotating arm 520a and the second rotating arm 520b are respectively rotated into one end of the first limiting groove 5122a communicated with the first sliding groove 5121a and one end of the second limiting groove 5122b communicated with the second sliding groove 5121b, due to the support of the base plate 511, when the first rotating arm 520a and the second rotating arm 520b are in the same plane, the first rotating arm 520a and the second rotating arm 520b cannot continue to rotate, thereby achieving limiting of the first rotating arm 520a and the second rotating arm 520b. When the ends of the first rotating arm 520a and the second rotating arm 520b away from the base 51 are close to each other, that is, when the electronic device 1000 is in a folded state, the rotating arm 52 and the second rotating arm 520b are respectively partially rotated out of the first sliding groove 5121a and the second sliding groove 5121b, and due to the blocking of the limiting piece 53, at least part of the structure of the first rotating arm 520a and the second rotating arm 520b is located in the first sliding groove 5121a and the second sliding groove 5121b, thereby avoiding the first rotating arm 520a and the second rotating arm 520b from being separated from the base 51 in the folded state of the electronic device 1000.

[0074] Please refer to Figure 12 A first mounting hole 5131 can be formed on the mounting plate 513, and a second mounting hole 530 can be formed on the limiting piece 53. A fixing piece such as a screw passes through the first mounting hole 5131 and the second mounting hole 530 to achieve fixed connection of the limiting piece 53 and the mounting plate 513.

[0075] A first positioning structure 5132 such as a clamping block structure is arranged on the second surface 5130 of the mounting plate 513, and the first positioning structure 5132 is clamped and matched with the limiting piece 53. On the one hand, the first positioning structure 5132 achieves quick positioning of the limiting piece 53 and the mounting plate 513, and on the other hand, the first positioning structure 5132 is used to limit sliding of the limiting piece 53 relative to the mounting plate 513, thereby improving reliability of connection of the mounting plate 513 and the limiting piece 53.

The base plate 511 is provided with a fixing hole 5110, and a fixing member such as a screw is arranged in the fixing hole 5110 and the fixing portion 410 to achieve fixed connection with the main support plate 41 and the support frame 40. Specifically, the fixing hole 5110 includes a first fixing hole 5110a arranged on the base plate 511 of the first rotating shaft module 501, the first fixing hole 5110a corresponding to the first fixing portion 410a to achieve fixed connection of the first rotating shaft module 501 and the support frame 40; the fixing hole 5110 further includes a second fixing hole 5110b arranged on the base plate 511 of the second rotating shaft module 502, the second fixing hole 5110b corresponding to the second fixing portion 410b to achieve fixed connection of the second rotating shaft module 502 and the support frame 40.

[0078] Please refer to Figure 15 , Figure 15 is Figure 14 the base is shown in a deformed perspective view.

[0079] Optionally, the base plate 511 can include a first base plate 511a and a second base plate 511b, the first base plate 511a is fixedly connected with the first base portion 512, and the second base plate 511b is fixedly connected with the second base portion 514. One end of the first base plate 511a away from the first base portion 512 is provided with a first recess 5111 and a first protrusion 5112, and one end of the second base plate 511b away from the second base portion 514 is provided with a second recess 5113 and a second protrusion 5114, wherein the first recess 5111 is arranged corresponding to the second protrusion 5114, and the first protrusion 5112 is arranged corresponding to the second recess 5113. The first recess 5111 clamps and accommodates the second protrusion 5114, and the protrusion clamps and accommodates the second recess 5113, which on one hand realizes quick splicing of the first base plate 511a and the second base plate 511b, and on the other hand prevents dislocation of the first base plate 511a and the second base plate 511b. In the above manner, the processing difficulty of the base 51 can be reduced, and batch production of the base 51 is facilitated.

[0080] It can be understood that one side of the first base plate 511a facing the second base plate 511b is provided with a clamping groove 5115, and one side of the second base plate 511b facing the first base plate 511a is formed with a clamping plate 5116 clamping and accommodating in the clamping groove 5115 to achieve splicing connection of the first base plate 511a and the second base plate 511b. The fixing hole 5110 is arranged on the clamping plate 5116, and the second base plate 5116 is fixed by the fixing hole 5110, thereby achieving fixed connection of the first base plate 511a.

[0081] Optionally, the first base 512 is provided with two first pivot grooves 5121 (for example, a first sliding groove 5121a and a second sliding groove 5121b) on a surface facing the second base 514, and the second sliding groove 5121b is provided adjacent to the first sliding groove 5121a; the second base 514 is provided with two second pivot grooves 5141 (for example, a third sliding groove 5141a and a fourth sliding groove 5141b) on a surface facing the first base 512, and the third sliding groove 5141a is provided corresponding to the first sliding groove 5121a, and the fourth sliding groove 5141b is provided corresponding to the second sliding groove 5121b. The first rotating arm 520a is accommodated in one end of the accommodating groove 510 and is pivotally connected with the first sliding groove 5121a and the third sliding groove 5141a, respectively; the second rotating arm 520b is accommodated in one end of the accommodating groove 510 and is pivotally connected with the second sliding groove 5121b and the fourth sliding groove 5141b, respectively. In other words, the two second pivot grooves 5141 are provided corresponding to the two first pivot grooves 5121, and the first rotating arm 520a and the second rotating arm 520b are accommodated in one end of the accommodating groove 510 and are accommodated in the corresponding first pivot groove 5121 and the second pivot groove 5141, respectively, thereby realizing the rotating connection of the first rotating arm 520a, the second rotating arm 520b and the base 51. In this way, the risk of the first rotating arm 520a and the second rotating arm 520b falling off along the rotating axis direction can be reduced, and the rotating connection of the first rotating arm 520a, the second rotating arm 520b and the base 51 is more stable and reliable.

[0082] The first base 512 can include a first surface 5120 away from the base plate 511, and two ends of the first sliding groove 5121a and the second sliding groove 5121b are connected to the first surface 5120, so as to facilitate the first rotating arm 520a and the second rotating arm 520b to be respectively rotated into or at least partially rotated out of the first sliding groove 5121a and the second sliding groove 5121b; the second base 514 can include a third surface 5140 away from the base plate 511, and the third surface 5140 and the fourth surface are substantially located on the same plane, so that the display module 300 can be flatly attached to the base 51. Two ends of the third sliding groove 5141a and the fourth sliding groove 5141b are connected to the third surface 5140, and on the one hand, the first rotating arm 520a and the second rotating arm 520b can be respectively rotated into or at least partially rotated out of the third sliding groove 5141a and the fourth sliding groove 5141b.

[0083] The base 51 can further include a mounting plate 513 disposed on the side of the first base 512 away from the substrate 511. The mounting plate 513 can include a second surface 5130 parallel to the first surface 5120, and the first surface 5120 and the second surface 5130 are arranged in a stepped manner, that is, the base 51 includes the first surface 5120 and the second surface 5130 arranged in a stepped manner. The limiting member 53 is fixed on the second surface 5130, and the side of the limiting member 53 away from the second surface 5130 is flush with or slightly lower than the first surface 5120, so as to avoid the display module 300 being uneven when the display module 300 is attached to the rotating shaft module 50, affecting the touch feeling of the display module 300.

[0084] Optionally, the first base 512 further has two limiting grooves 5122 (for example, a first limiting groove 5122a and a second limiting groove 5122b) disposed on the first surface 5120. The first limiting groove 5122a is in communication with the first sliding groove 5121a, and the second limiting groove 5122b is in communication with the second sliding groove 5121b. The limiting member 53 is respectively clamped and accommodated in the first limiting groove 5122a and the second limiting groove 5122b, and is used to block the first rotating arm 520a and the second rotating arm 520b from being separated from the base 51 in the folded state of the electronic device 1000.

[0085] The rotating arm 52 can include a rotating arm body 521, a pivot portion 522, and a rotating portion 523 respectively disposed at two ends of the rotating arm body 521. The pivot portion 522 is pivotally connected to the base 51, and the rotating portion 523 is rotatably connected to the supporting plate 30.

[0086] Specifically, the pivot portion 522 can include a pivot portion body 5221 and a first sliding block 5222 fixed on the pivot portion body 5221. The first sliding block 5222 is accommodated in the first pivot groove 5121 and can slide along the first pivot groove 5121, so as to realize the rotatable connection between the rotating arm 52 and the base 51. Specifically, the first sliding block 5222 of the first rotating arm 520a is slidingly connected in the first sliding groove 5121a, and the first sliding block 5222 of the second rotating arm 520b is slidingly connected in the second sliding groove 5121b.

[0087] Optionally, the first sliding block 5222 is in a circular arc shape and corresponds to the shape of the first pivot slot 5121, and the first sliding block 5222 can be screwed into or partially screwed out of the first pivot slot 5121 to achieve the rotational connection of the first rotating arm 520a, the second rotating arm 520b and the base 51. Specifically, when the electronic device 1000 is in an unfolded state, i.e., the first rotating arm 520a and the second rotating arm 520b are substantially located in the same plane, the first sliding block 5222 of the first rotating arm 520a and the second rotating arm 520b is respectively fully accommodated in the first sliding slot 5121a and the second sliding slot 5121b. When the electronic device 1000 is in a folded state, i.e., the first rotating arm 520a and the second rotating arm 520b are parallel to each other, the first sliding block 5222 of the first rotating arm 520a and the second rotating arm 520b is partially accommodated in the corresponding first sliding slot 5121a and the second sliding slot 5121b. Understandably, at this time, when the electronic device 1000 falls, the first rotating arm 520a and the second rotating arm 520b are easily separated from the base 51.

[0088] Please refer to Figure 16 , Figure 16 is Figure 11 the perspective view of the rotating arm in the folding module.

[0089] In an embodiment, the pivot part 522 can include a pivot part body 5221, a first sliding block 5222 and a second sliding block 5223, wherein the first sliding block 5222 and the second sliding block 5223 are respectively located on the opposite sides of the pivot part body 5221. The first sliding block 5222 is accommodated in the first pivot slot 5121 and can slide along the first pivot slot 5121, and the second sliding block 5223 can be accommodated in the second pivot slot 5141 and can slide along the second pivot slot 5141. Specifically, the first sliding block 5222 of the first rotating arm 520a is slidingly connected in the first sliding slot 5121a, and the second sliding block 5223 of the first rotating arm 520a is slidingly connected in the third sliding slot 5141a; the first sliding block 5222 of the second rotating arm 520b is slidingly connected in the second sliding slot 5121b, and the second sliding block 5223 of the second rotating arm 520b is slidingly connected in the fourth sliding slot 5141b. In this way, the risk of the first rotating arm 520a and the second rotating arm 520b falling off along the rotating axis direction can be reduced, and the rotational connection of the first rotating arm 520a, the second rotating arm 520b and the base 51 is more stable and reliable.

[0090] Further, the pivot part 522 can further include a clamping block 5224, which is arranged on the side of the first sliding block 5222 away from the pivot part body 5221, and the clamping block 5224 is located at the end of the first sliding block 5222 away from the adapter 523, so that the clamping block 5224 is accommodated in the first pivot slot 5121 and can slide in the first pivot slot 5121.

[0091] Please refer to Figure 9 and Figure 10 When the first rotating arm 520a and the second rotating arm 520b are substantially located in the same plane, the clamping block 5224 of the first rotating arm 520a is located at one end of the first sliding groove 5121a close to the second sliding groove 5121b, and the clamping block 5224 of the second rotating arm 520b is located at one end of the second sliding groove 5121b close to the first sliding groove 5121a. When the first rotating arm 520a and the second rotating arm 520b are parallel to each other, the clamping block 5224 of the first rotating arm 520a slides to one end of the first sliding groove 5121a away from the second sliding groove 5121b, and the clamping block 5224 of the second rotating arm 520b slides to one end of the second sliding groove 5121b away from the first sliding groove 5121a. Since the limiting piece 53 is clamped in the first limiting groove 5122a and the second limiting groove 5122b, the limiting piece 53 can simultaneously cooperate with the clamping block 5224 of the first rotating arm 520a and the clamping block 5224 of the second rotating arm 520b, which can not only ensure that the first sliding block 5222 of the first rotating arm 520a can partially slide out of the first sliding groove 5121a and the first sliding block 5222 of the second rotating arm 520b can partially slide out of the second sliding groove 5121b, thereby enabling the first rotating arm 520a and the second rotating arm 520b to be parallel to each other, but also can block the first rotating arm 520a and the second rotating arm 520b from being separated from the first sliding groove 5121a and the second sliding groove 5121b, respectively.

[0092] It can be understood that the depth of the first pivoting groove 5121 substantially corresponds to the sum of the thicknesses of the first sliding block 5222 and the clamping block 5224, so that the clamping block 5224 can slide with the first sliding block 5222 in the first pivoting groove 5121. The limiting piece 53 is clamped in the first limiting groove 5122a and the second limiting groove 5122b and partially enters the first pivoting groove 5121, which can not only ensure that the first sliding block 5222 is rotated into or at least partially rotated out of the first pivoting groove 5121, but also can block the first sliding block 5222 to avoid the first sliding block 5222 from being completely rotated out of the first pivoting groove 5121, thereby improving the reliability of the electronic device 1000 in the folded state.

[0093] The adapter 523 can include an adapter body 5231 and an adapter shaft 5232, and the adapter 523 is rotatably connected to the support plate 30 through the adapter shaft 5232. Specifically, the first rotating arm 520a is rotatably connected to the first support plate 301 through a corresponding adapter 523, and the second rotating arm 520b is rotatably connected to the second support plate 302 through a corresponding adapter 523. In this embodiment, the adapter body 5231 can be provided with a rotating hole 5233, and the adapter shaft is accommodated and rotatably connected in the rotating hole 5233. Such a design can improve the reliability and stability of the connection between the adapter 523 and the support plate 30, and prevent the adapter 523 and the support plate 30 from being stuck during rotation. In other embodiments, the adapter body 5231 can be fixedly connected to the adapter shaft 5232.

[0094] Please refer to Figure 17 The limiting piece 53 can include a limiting piece body 531 and two limiting portions 532 (such as a first limiting portion 532a and a first limiting portion 532b) fixedly connected to the limiting piece body 531, wherein the first limiting portion 532a and the first limiting portion 532b are oppositely arranged and located on the same side of the limiting piece body 531. The first limiting portion 532a and the first limiting portion 532b correspond to the first limiting slot 5122a and the second limiting slot 5122b, respectively. The first limiting portion 532a is accommodated in the first limiting slot 5122a to block the clamping block 5224 of the first rotating arm 520a, thereby preventing the first rotating arm 520a from being separated from the first pivot slot 5121. The first limiting portion 532b is accommodated in the second limiting slot 5122b to block the clamping block 5224 of the second rotating arm 520b, thereby preventing the second rotating arm 520b from being separated from the second pivot slot 5141.

[0095] Further, the limiting portion 532 includes a top surface 5321, and the limiting portion 532 is clamped and accommodated in the limiting slot 5122, and the top surface 5321 is flush with or slightly lower than the first surface 5120, so that the surface consistency of the adapter shaft assembly connected to the display module 300 is good, thereby ensuring that the display module 300 is uniformly stressed and has good reliability.

[0096] The side of the limiting piece body 531 facing the second surface 5130 is provided with a second positioning structure 5311 such as a clamping groove structure, and the second positioning structure 5311 corresponds to and clamps with the first positioning structure 5132, thereby achieving clamping and fixing of the limiting piece and the mounting plate 513.

[0097] It can be understood that when installed, the first sliding block 5222 of the first rotating arm 520a is screwed into one end of the first limiting slot 5122a provided in the first sliding groove 5121a, and the second sliding block 5223 of the first rotating arm 520a is screwed into the third sliding groove 5141a, so that the first rotating arm 520a is rotatably connected with the base 51. The first sliding block 5222 of the second rotating arm 520b is screwed into one end of the second limiting slot 5122b provided in the second sliding groove 5121b, and the second sliding block 5223 of the second rotating arm 520b is screwed into the fourth sliding groove 5141b, so that the second rotating arm 520b is rotatably connected with the base 51. The limiting member body 531 is placed on the second surface 5130 and fixedly connected with the mounting plate 513, and the first limiting portion 532a and the first limiting portion 532b are respectively clamped and accommodated in the first limiting slot 5122a and the second limiting slot 5122b, for blocking the first rotating arm 520a and the second rotating arm 520b from being separated from the base 51.

[0098] Please refer to Figure 9 and Figure 10 When the electronic device 1000 is in the unfolded state, that is, the first rotating arm 520a and the second rotating arm 520b are located in substantially the same plane, the first sliding block 5222 of the first rotating arm 520a and the first sliding block 5222 of the second rotating arm 520b are respectively fully accommodated in the first sliding groove 5121a and the second sliding groove 5121b, at this time, the clamping block 5224 of the first rotating arm 520a is located at one end of the first sliding groove 5121a away from the first limiting slot 5122a, and the clamping block 5224 of the second rotating arm 520b is located at one end of the second sliding groove 5121b away from the second limiting slot 5122b. Due to the support of the base plate 511, the clamping block 5224 of the first rotating arm 520a and the clamping block 5224 of the second rotating arm 520b are respectively fully accommodated in the first sliding groove 5121a and the second sliding groove 5121b, and cannot protrude from the first surface 5120. When the electronic device 1000 is in the folded state, that is, the first rotating arm 520a is parallel to the second rotating arm 520b, the first sliding block 5222 of the first rotating arm 520a and the first sliding block 5222 of the second rotating arm 520b are respectively partially accommodated in the first sliding groove 5121a and the second sliding groove 5121b, at this time, the clamping block 5224 of the first rotating arm 520a abuts against the first limiting portion 532a, and the clamping block 5224 of the second rotating arm 520b abuts against the first limiting portion 532b. Due to the blocking of the first limiting portion 532a and the first limiting portion 532b, the first sliding block 5222 of the first rotating arm 520a and the first sliding block 5222 of the second rotating arm 520b are at least partially accommodated in the first sliding groove 5121a and the second sliding groove 5121b, respectively. Even if the electronic device 1000 falls in the folded state, the first rotating arm 520a and the second rotating arm 520b will not be separated from the first sliding groove 5121a and the second sliding groove 5121b.

[0099] The rotating shaft module 50 provided by the embodiment of the present application simultaneously blocks the first rotating arm 520a and the second rotating arm 520b through the limiting piece 53, so as to optimize the structure of the rotating module and save the occupied space of the rotating shaft module 50.
