Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the above-mentioned features.

[0015] It can be understood that names such as "first housing", "second housing", "housing", and "case" can be converted into each other. For example, the "first housing" may be called the "second housing".

[0016] Specifically, referring to FIGS. 3 and 4, FIG. 4 discloses a schematic structural diagram of a housing 100 according to an embodiment of the present invention. The housing 100 may be two housings, for example, a first housing 200 and a second housing 300. The housing 100 includes a housing body 10 and a connecting member 20. Here, the housing body 10 is used to support the display module 900 and is used to mount electronic components such as a circuit board and a battery. The connecting member 20 is attached to the housing body 10 and is used to be connected to the folding assembly 500, thereby realizing the connection between the housing 100 and the folding assembly 500.

[0017] Specifically, referring to FIG. 4, the housing body 10 may include a bottom plate 11, side walls 12, and a substrate 13. Side walls 12 can be installed at the edges of the bottom plate 11, that is, the side walls 12 can be installed surrounding the edges of the bottom plate 11. The bottom plate 11 and the side walls 12 form an accommodation space for accommodating electronic components such as a camera, a circuit board, a battery, and the display module 900. The substrate 13 and the bottom plate 11 are installed opposite to each other and are connected and fixed to the side walls 12. That is, the side walls 12 are surrounded by the four sides of the substrate 13 and are fixed together with the substrate 13 to form a middle frame. The substrate 13 can divide the accommodation space into two parts to form a first accommodation space and a second accommodation space. The first accommodation space is located between the bottom plate 11 and the substrate 13 and is used to accommodate electronic elements such as a camera, a circuit board, and a battery. The second accommodation space is located on the side of the substrate 13 away from the bottom plate 11 and is used to accommodate the display module 900.

[0018] Referring to FIG. 4, the bottom plate 11 may have a plate-like structure, which may be rectangular or angular rectangular, etc., and may be formed of plastic, glass, ceramic, fiber composite material, metal (e.g., stainless steel, aluminum, etc.), or other suitable materials or combinations thereof. In some cases, a part 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 of the structures constituting the bottom plate 11 may be formed of metal parts.

[0019] Mounting portions 14 are provided on the bottom plate 11 and are used for attaching the connecting member 20. There may be a plurality of mounting portions 14. For example, in FIG. 4, there are two mounting portions 14, which are the first mounting portion 141 and the second mounting portion 142 respectively. The first mounting portion 141 and the second mounting portion 142 are respectively installed on one side of the bottom plate 11. The first mounting portion 141 and the second mounting portion 142 are respectively installed close to the side walls 12 on both sides.

[0020] The mounting portion 14 is a hole recessed inward from the bottom plate 11 and is used for being inserted and fixed with the connecting member 20. Also, the mounting portion 14 can be fixed to the connecting member 20 with an adhesive.

[0021] The side walls 12 are surrounded by the edges of the bottom plate 11 and extend and are installed toward the same side of the bottom plate 11. The side walls 12 are broken on the side where the mounting portions 14 of the bottom plate 11 are installed to form an opening, thereby creating a space for the folding assembly 500. That is, the side walls 12 are installed on three sides of the bottom plate 11, and on the remaining one side, the side walls 12 are not installed and an opening is formed. The mounting portion 14 is installed adjacent to the remaining one side of the bottom plate 11.

[0022] The wall thickness of the side walls 12 on both sides of the opening is smaller than that of the walls at other positions, thereby creating a space for the folding assembly 500. As can be understood, there may be one or more openings, and there may be two or three openings. For example, in FIG. 4, the side walls 12 may be installed on two opposite sides of the bottom plate 11, and one opening may be formed on each of the other two sides. Of course, the side walls 12 may be installed on two adjacent sides of the bottom plate 11, and one opening may be formed on each of the other two sides.

[0023] In one embodiment, the bottom plate 11 and the side walls 12 are of an integral structure, and the side walls 12 are manufactured using the same material as the bottom plate 11.

[0024] In one embodiment, referring to FIG. 4, the side walls 12 and the substrate 13 are of an integral structure, and the substrate 13 can be manufactured using the same material as the side walls 12. In one embodiment, the substrate 13 does not cover the bottom plate 11 at the opening, creating a space for the folding assembly 500, whereby a part of the structure of the folding assembly 500 is installed on the bottom plate 11.

[0025] Referring to FIGS. 4, 5 and 6, FIGS. 5 and 6 respectively disclose a structural schematic diagram of the connecting member 20 according to an embodiment of the present invention. The connecting member 20 is used for connecting to the folding assembly 500. There may be a plurality of connecting members 20. For example, there may be two connecting members 20, namely the first connecting member 15 and the second connecting member 16 respectively. The first connecting member 15 is attached to the mounting portion 14, for example, the first mounting portion 141. The second connecting member 16 is attached to the mounting portion 14, for example, the second mounting portion 142.

[0026] Specifically, the connecting member 20 can include a connecting member body 21 and a buffer arm 22. The connecting member body 21 is used for being attached to the mounting portion 14, for example, the first mounting portion 141 or the second mounting portion 142. The buffer arm 22 is installed in the opening of the connecting member body 21 and extends outside the opening, and is used for being slidably connected to the folding assembly 500.

[0027] Referring to FIG. 5, the connection member body 21 extends toward one side of the bottom plate 11 and a plug post 211 is installed thereon, and thereby it is used to be inserted into the mounting portion 14 on the bottom plate 11, for example, the first mounting portion 141 or the second mounting portion 142. As can be understood, the connection member body 21 may be fixed and connected to the mounting portion 14, for example, the first mounting portion 141 or the second mounting portion 142 by means such as adhesive bonding or bolt fixing. Of course, the connection member body 21 and the bottom plate 11 may also be of an integral structure.

[0028] Referring to FIG. 6, the connection member body 21 extends on one side away from the bottom plate 11 and on both sides in the direction from the connection member body 21 toward the buffer arm 22, and connection walls 212 are installed, for example, the first connection wall 213 and the second connection wall 215. The first connection wall 213 protrudes toward one side of the second connection wall 215 and a positioning post 2131 is installed thereon. The second connection wall 215 protrudes toward one side of the first connection wall 213 and a positioning post 2151 is installed thereon. The positioning post 2131 and the positioning post 2151 are installed opposite to each other, and gaps between the positioning post 2131 and the positioning post 2151 and the connection member body 21 form tracks, for example, the first track 214 and the second track 216. The positioning post 2131 and the positioning post 2151 are engaged with the folding assembly 500, and a part of the structure of the folding assembly 500 slides in the tracks, so that the folding assembly 500 rotates around the positioning post 2131 and the positioning post 2151. In one embodiment, the first connection wall 213 or the second connection wall 215 may be omitted.

[0029] In one embodiment, a concave groove 217 is provided that recesses inward from the surface of the connection member body 21 away from the bottom plate 11, creating a space for the folding assembly 500. The concave groove 217 is positioned between the positioning post 2131 and the positioning post 2151. To facilitate the rotation of the folding assembly 500, the track is arc-shaped, facilitating the rotation of the folding assembly 500 from outside the track, realizing the disassembly of the folding assembly 500 and the connection member 20, facilitating the screwing of the folding assembly 500 into the track, and realizing the assembly of the folding assembly 500 and the connection member 20 and the subsequent use during the folding of the electronic device 000.

[0030] Referring to FIGS. 5 and 6, there may be one or more buffer arms 22. For example, there are two buffer arms 22, namely the first buffer arm 221 and the second buffer arm 222 respectively. A gap is provided between two adjacent buffer arms 22, and a space can be created for the folding assembly 500. For example, a gap 23 is provided between the first buffer arm 221 and the second buffer arm 222. The buffer arm 22 is provided with strip-shaped through holes, and each strip-shaped through hole is arranged oppositely, so that a part of the structure of the folding assembly 500 passes through the strip-shaped through holes together and slides in the longitudinal direction of the strip-shaped through holes. For example, a first strip-shaped through hole 2211 is provided in the first buffer arm 221, and a second strip-shaped through hole 2221 is provided in the second buffer arm 222.

[0031] Referring to FIG. 7, it discloses a structural schematic diagram of a folding assembly 500 according to an embodiment of the present invention. The folding assembly 500 can include a substrate 30 (for example, a first substrate 31 and a second substrate 32), a support frame 40, and a rotating shaft module 50 (for example, a first rotating shaft module 60 and a second rotating shaft module 70). Specifically, the support frame 40 is installed between two adjacent housings 100. For example, the support frame 40 is installed between a first housing 200 and a second housing 300. The first rotating shaft module 60 and the second rotating shaft module 70 in the rotating shaft module 50 are respectively located at both ends of the support frame 40 and are fixedly connected to the support frame 40. That is, the first rotating shaft module 60 is located at one end of the support frame 40, and the second rotating shaft module 70 is located at the other end of the support frame 40. The rotating shaft module 50 is installed between two adjacent housings 100 and is respectively connected to the two adjacent housings 100. When the rotating shaft module 50 rotates, it is possible to fold the two adjacent housings 100. For example, both the first rotating shaft module 60 and the second rotating shaft module 70 can connect the first housing 200 and the second housing 300 to each other. The first substrate 31 and the second substrate 32 on the substrate 30 are symmetrically installed and are located on two opposite sides of the support frame 40. That is, the first substrate 31 is disposed on the first side of the support frame 40, and the second substrate 32 is disposed on the second side opposite to the first side of the support frame 40. The first substrate 31 is located between the first rotating shaft module 60 and the second rotating shaft module 70 and is rotatably connected to the first housing 200. The first substrate 31 is further rotatably connected to the first rotating shaft module 60 and the second rotating shaft module 70 respectively. The second substrate 32 is located between the first rotating shaft module 60 and the second rotating shaft module 70 and is rotatably connected to the second housing 300 respectively. The second substrate 32 is further rotatably connected to the first rotating shaft module 60 and the second rotating shaft module 70 respectively. The first substrate 31 and the second substrate 32 are mounted on the support frame 40 and are used to support the display module 900.The first substrate 31 and the second substrate 32 are fixed together with the display module 900 and are used to protect the display module 900, and can prevent the display module 900 from being bent and damaged when the folding assembly 500 is folded.

[0032] Referring to FIGS. 7, 8 and 9, FIGS. 8 and 9 disclose structural schematic diagrams of different viewing angles of the substrate 30 according to an embodiment of the present invention. The substrate 30 can include a plurality. For example, the substrate 30 can include two, namely the first substrate 31 and the second substrate 32 respectively. The first substrate 31 and the second substrate 32 are symmetrically installed and are respectively located on both sides of the support frame 40. That is, the first substrate 31 is arranged on the first side of the support frame 40, and the second substrate 32 is arranged on the second side opposite to the first side of the support frame 40. It is used to adhere to the display module 900 and is used to support the display module 900 during the folding or unfolding process of the housing 100, enabling the display module 900 to be bent or folded, and making the surface of the display module 900 flat when unfolded.

[0033] Specifically, the substrate 30 can include a connection plate 33. The connection plate 33 may have a strip-shaped plate structure and is used to adhere and fix to the display module 900. Connection portions, for example, a first connection portion 34 and a second connection portion 35, are respectively installed at both ends of one side edge of the connection plate 33 and are used to be rotatably connected to the connection member 20. The shape of the first connection portion 34 conforms to the concave groove 217 of the second connection member 16, whereby the first connection portion 34 is installed in the concave groove 217. The first connection portion 34 respectively projects corresponding to the first track 214 and the second track 216 of the second connection member 16 to install a slider 341. The slider 341 is located on both sides of the first connection portion 34, whereby the slider 341 slides within the track, and the substrate 30 realizes relative rotation with the connection member 20. The shape of the second connection portion 35 conforms to the concave groove 217 of the first connection member 15, whereby the second connection portion 35 is installed in the concave groove 217. The second connection portion 35 respectively projects corresponding to the first track 214 and the second track 216 of the first connection member 15 to install a slider 351. The slider 351 is located on both sides of the second connection portion 35, whereby the slider 351 slides within the track, and the substrate 30 realizes relative rotation with the connection member 20.

[0034] The connection plate 33 projects and a yield plate 36 is installed on the other side away from the first connection portion 34 and the second connection portion 35. Thereby, when the folding assembly 500 is folded, it is disposed inside the support frame 40, and thereby space is created for the display module 900.

[0035] The connection board 33 has connection parts, for example, a third connection part 37 and a fourth connection part 38, installed on both sides of the position yielding board 36, and is used to connect to the rotation axis module 50 respectively.

[0040] Referring to FIGS. 11, 12, and 13, FIG. 13 discloses an exploded view of the mounting housing 80 according to an embodiment of the present invention. The mounting housing 80 can include a main housing 81, a support plate 82, and an elastic member 83. Specifically, the main housing 81 is fixed to the support frame 40 and is used for mounting the rotary shaft assembly 90. The support plate 82 is attached to the main housing 81 and mounted on the rotary shaft assembly 90. The support plate 82 is used to support the display module 900. When the rotary shaft assembly 90 rotates, the support plate 82 moves closer to the main housing 81 side, thereby creating a space for the display module 900, and moves away from the main housing 81 side, thereby flattening the display module 900. The elastic member 83 is installed between the main housing 81 and the support plate 82, is used to support the support plate 82, and is used to buffer the relative movement between the main housing 81 and the support plate 82. The main housing 81 can include a mounting plate 811, enclosing plates (for example, a first enclosing plate 812, a second enclosing plate 813, a third enclosing plate 814, and a fourth enclosing plate 815), and dividing plates (a first dividing plate 816 and a second dividing plate 817). A plurality of enclosing plates, for example, the first enclosing plate 812, the second enclosing plate 813, the third enclosing plate 814, and the fourth enclosing plate 815, are connected end to end in sequence, installed around the four sides of the mounting plate 811, and connected and fixed to the mounting plate 811, thereby forming an accommodation space, which is used for mounting the rotary shaft assembly 90. The dividing plates, for example, the first dividing plate 816 and the second dividing plate 817, are installed in the accommodation space and fixedly connected to at least one of the mounting plate 811 and the enclosing plates, thereby reinforcing the strength of the main housing 81, fixing and supporting the rotary shaft module 50, and also used for dividing the accommodation space.

[0041] A fixing portion 8111 is installed on the mounting plate 811 and is used to be fixed and connected to the first fixing portion 411 or the second fixing portion 412. For example, it is fixed by bolts, screws, adhered by an adhesive, or fixed by a snap connection or other methods. A guide mounting portion 8112 is installed on the mounting plate 811 and is used to mount the support plate 82 and the elastic member 83. In one embodiment, the guide mounting portion 8112 is a through hole, which is convenient for inserting the support plate 82 and enables the support plate 82 to move along the extending direction of the through hole.

[0042] The central portion on one side of the second enclosing plate 813 and the fourth enclosing plate 815 away from the mounting plate 811 is recessed toward the mounting plate 811 to form a receiving groove, thereby creating a space for other members, such as the support plate 82, the substrate 30, and the display module 900. Sliders 8151 and 8152 are installed on the side of the fourth enclosing plate 815 facing the second enclosing plate 813, so that the slider 8151 is installed to slide on the arc-shaped slide track 371 of the first substrate 31, and the slider 8152 is installed to slide on the arc-shaped slide track 381 of the second substrate 32.

[0043] The partition plate is installed such that, for example, the first partition plate 816 and the second partition plate 817 face the second enclosure plate 813 respectively. The first partition plate 816 is positioned between the second enclosure plate 813 and the second partition plate 817. The central part on one side of the partition plate away from the mounting plate 811, for example, the first partition plate 816 and the second partition plate 817, is recessed toward the mounting plate 811 to form a receiving groove, thereby creating a space for other members, such as the support plate 82, the substrate 30, and the display module 900. Sliders 8171 and 8172 are installed on the side of the second partition plate 817 facing the fourth enclosure plate 815, so that the slider 8171 is installed to slide on the arc-shaped slide track 371 of the first substrate 31, and the slider 8172 is installed to slide on the arc-shaped slide track 381 of the second substrate 32. The sliders 8171 and 8172 of the second partition plate 817, and the sliders 8151 and 8152 of the fourth enclosure plate 815 cooperate to realize the rotational connection of the first substrate 31, the second substrate 32, and the rotation axis module 50. In one embodiment, all or part of the partition plate can be omitted. In one embodiment, at most one of the second partition plate 817 and the fourth enclosure plate 815 can be omitted.

[0044] As can be understood, the main housing 81 can be omitted, and the support frame 40 substitutes for the function of the main housing 81 and is used to mount and support the rotation axis assembly 90. In one embodiment, the support frame 40 can be omitted, and the main housing 81 is used to mount and support the rotation axis assembly 90 and the substrate 30. Therefore, the main housing 81 can be called the "support frame". In one embodiment, since the support frame 40 and the main housing 81 are of an integral structure, the main housing 81 can also be called the "support frame".

[0045] The support plate 82 is installed opposite to the mounting plate 811. The support plate 82 is positioned in the receiving groove of the first enclosing plate 813 and the receiving groove of the dividing plate, and is in contact with the rotating shaft assembly 90. The support plate 82 has a plate-like structure, and a mounting hole 821 is installed corresponding to the fixing portion 8111 of the mounting plate 811. Through the mounting hole 821, the fixing portion 8111 of the bottom plate 811 and the first fixing portion 411 or the second fixing portion 412 of the support frame 40 can be attached and fixed together or removed.

[0046] A guide post 822 is installed on the side of the support plate 82 facing the mounting plate 811. The guide post 822 is installed to extend toward the mounting plate 811 side. The guide post 822 is disposed in the guide mounting portion 8112 and moves relative to the guide mounting portion 8112 in the extending direction of the guide post 822.

[0047] In one embodiment, a contact portion, for example, a first contact portion 823, a second contact portion 824, and a third contact portion 825, is installed on the surface of the support plate 82 facing the mounting plate 811 and protrudes. The contact portion is used to contact the rotating shaft assembly 90. When the rotating shaft assembly 90 rotates, the distance between the support plate 82 and the mounting plate 811 is adjusted, thereby creating a space for the display module 900 so that the electronic device 000 can be folded better.

[0048] The elastic member 83 is an elastic structure made of a spring or other elastic material. The elastic member 83 has a function of resetting the support plate 82 and can prevent the support plate 82 from separating from the mounting plate 811, thereby preventing the display module 900 from separating from the housing 100 and being unable to be folded. Here, the elastic member 83 is a spring. The elastic member 83 is externally fitted around the guide post 822 and is installed in the guide mounting portion 8112 together with the guide post 822. One end of the elastic member 83 is in contact with the support plate 82, and the other end is in contact with the mounting plate 811. In one embodiment, one end of the elastic member 83 is connected to the support plate 82, and the other end is connected to the mounting plate 811.

[0049] Referring to FIGS. 12, 14, 15 and 16, FIG. 14 discloses a structural schematic diagram of a rotating shaft assembly 90 according to an embodiment of the present invention, FIG. 15 discloses a partial structural schematic diagram of the structure of the rotating shaft assembly 90 according to an embodiment of the present invention, and FIG. 16 discloses a partial cross-sectional schematic diagram of the structure of the rotating shaft assembly 90 according to an embodiment of the present invention. The rotating shaft assembly 90 is fixed in the accommodation space. The rotating shaft assembly 90 can include a first rotating shaft assembly 91, a second rotating shaft assembly 92, and a link assembly 93. Here, the first rotating shaft assembly 91 and the second rotating shaft assembly 92 are fixed to the mounting housing 80. The first rotating shaft assembly 91 is used to be connected to the connecting member 20 of the first housing 200. The second rotating shaft assembly 92 is used to be connected to the connecting member 20 of the second housing 300. The link assembly 93 is used to be connected to the first rotating shaft assembly 91 and the second rotating shaft assembly 92, so that the first rotating shaft assembly 91 and the second rotating shaft assembly 92 can rotate synchronously.

[0050] Specifically, the first rotation shaft assembly 91 can include a rotation shaft 911, a first positioning slider 912, a spring 913, a second positioning slider 914, a rotation arm 915, and a connection shaft 916. Here, the rotation shaft 911 can penetrate through the second surrounding plate 813 and the dividing plates (for example, the first dividing plate 816 and the second dividing plate 817) in sequence, and is attached to the second surrounding plate 813 and the dividing plates (for example, the first dividing plate 816 and the second dividing plate 817). The rotation shaft 911 is movable in the axial direction and rotatable in the radial direction. The rotation shaft 911 can include an engaging portion 9111, a pivot portion 9112, a threaded portion 9113, and a sliding portion 9114. The engaging portion 9111, the pivot portion 9112, and the sliding portion 9114 are connected in sequence along the axial direction. The threaded portion 9113 may be located at the central portion of the pivot portion 9112, thereby dividing the pivot portion 9112 into two parts. The engaging portion 9111 is used for engaging with the rotation arm 915, and the rotation arm 915 can be slid along the axial direction of the rotation shaft 911 by the engaging portion 9111, the rotation arm 915 can be rotated in the radial direction of the rotation shaft 911, and the rotation shaft 911 can be driven to rotate. The pivot portion 9112 is used for being rotatably connected to the second surrounding plate 813 and the dividing plates, for example, the first dividing plate 816, so that the mounting case 80 can support the rotation shaft 911. The threaded portion 9113 is used for screwing with the link assembly 93. The sliding portion 9114 is used for engaging with the first positioning slider 912, the second positioning slider 914, and the link assembly 93. The first positioning slider 912, the second positioning slider 914, and the link assembly 93 are slid along the axial direction of the rotation shaft 911, so that the rotation shaft 911 rotates along the radial direction of the rotation shaft 911 to drive the first positioning slider 912, the second positioning slider 914, and the link assembly 93 to rotate. The first positioning slider 912, the second positioning slider 914, and the link assembly 93 are located between the first dividing plate 816 and the second dividing plate 817. The first positioning slider 912 is located on the side close to the first dividing plate 816. The second positioning slider 914 is located on the side close to the second dividing plate 817. A part of the structure of the link assembly 93 is located between the first positioning slider 912 and the second positioning slider 914.

[0051] The spring 913 is externally fitted to the sliding portion 9114, positioned between the first positioning slider 912 and the second positioning slider 914, and positioned between the first positioning slider 912 and the partial structure of the link assembly 93.

[0052] The first positioning slider 912 is externally fitted to the sliding portion 9114, and a contact block 9121 is installed on the sliding portion 9114. The contact block 9121 extends and is installed on the side of the second rotating shaft assembly 92. The contact block 9121 is used to contact, for example, the support plate 82 at the second contact portion 824.

[0053] The second positioning slider 914 is externally fitted to the sliding portion 9114, and a contact block 9141 is installed on the second positioning slider 914. The contact block 9141 extends and is installed on the side of the second rotating shaft assembly 92. The contact block 9141 is used to contact, for example, the support plate 82 at the third contact portion 825. The side of the second positioning slider 914 facing the first positioning slider 912 is recessed inward to form a limiting groove, creating a space for the link assembly 93, enabling the rotating shaft 911 to rotate within a limited angular range, allowing the electronic device 000 to be flattened from a half-folded state, and preventing the electronic device 000 from being damaged when folded in the reverse direction.

[0054] The rotating arm 915 can include connecting arms (for example, a first connecting arm 9151 and a second connecting arm 9152) and a rotating connection portion 9153. The number of connecting arms can be one or more. For example, there are two connecting arms, namely the first connecting arm 9151 and the second connecting arm 9152 respectively. The first connecting arm 9151 and the second connecting arm 9152 are installed in parallel and extend toward the side of the connecting member 20, so that they are arranged alternately with the first buffer arm 221 and the second buffer arm 222. An engaging hole 9154 is installed in the first connecting arm 9151 and is used for engaging with the connecting shaft 916. Thereby, the connecting shaft 916 axially penetrates the engaging hole 9154, so that the first connecting arm 9151 can drive the connecting shaft 916 to rotate together in the radial direction of the connecting shaft 916. An engaging hole 9155 is installed in the second connecting arm 9152 and is used for engaging with the connecting shaft 916. Thereby, the connecting shaft 916 axially penetrates the engaging hole 9155, so that the second connecting arm 9152 can drive the connecting shaft 916 to rotate along the radial direction of the connecting shaft 916. The engaging hole 9154 and the engaging hole 9155 are coaxially installed.

[0055] The rotating connection portion 9153 is engaged with the engaging portion 9111 of the rotating shaft 911, and the rotating connection portion 9153 is installed within the support frame 40. The rotating arm 915 can be slid along the axial direction of the rotating shaft 911 by the engaging portion 9111, rotated in the radial direction of the rotating shaft 911, and drive the rotating shaft 911 to rotate. A contact block 9156 is installed on the rotating connection portion 9153, and the contact block 9156 extends toward the side of the second rotating shaft assembly 921. The contact block 9156 is used for contacting with a support plate 82, for example, the first contact portion 823.

[0056] The connecting shaft 916 is used to be connected to the first buffer arm 221 and the second buffer arm 222 of the connecting member 20. The connecting shaft 916 can be installed in the first strip-shaped through hole 2211 of the first buffer arm 221 and engaged with the first buffer arm 221, and can be installed in the second strip-shaped through hole 2221 of the second buffer arm 222 and engaged with the second buffer arm 222. The connecting shaft 916 is slidable in the first strip-shaped through hole 2211 and the second strip-shaped through hole 2221 respectively. When the first buffer arm 221 and the second buffer arm 222 rotate around the axis of the connecting shaft 916, the connecting shaft 916 can be driven to rotate.

[0057] The structure of the second rotating shaft assembly 92 is similar to that of the first rotating shaft assembly 91. For the structure and function of the second rotating shaft assembly 92 and its cooperation with other structures, reference can be made to the first rotating shaft assembly 91, and detailed description of the second rotating shaft assembly 92 will be omitted here. Here, only the structural components of the second rotating shaft assembly 92 are listed. Referring to FIGS. 12, 14, 15 and 16, the second rotating shaft assembly 92 can include a rotating shaft 921, a first positioning slider 922, a spring 923, a second positioning slider 924, a rotating arm 925 and a connecting shaft 926. The rotating shaft 921 can include an engaging portion 9211, a pivoting portion 9212, a threaded portion 9213 and a sliding portion 9214.

[0058] A contact block 9221 is installed on the first positioning slider 922, and the contact block 9221 extends and is installed on the side of the first rotating shaft assembly 91. The contact block 9221 is used to be in contact with the support plate 82, for example, the second contact portion 824.

[0059] The abutting block 9241 is installed on the second positioning slider 924, and the abutting block 9241 is extended and installed on the side of the first rotating shaft assembly 91. The abutting block 9241 is used to abut against the support plate 82, for example, the third abutting portion 825. The side of the second positioning slider 924 facing the first positioning slider 922 is recessed inward to form a limiting groove, creating a space for the link assembly 93, enabling the rotating shaft 921 to rotate within a limited angular range, allowing the electronic device 000 to be flattened from the half-folded state, and preventing the electronic device 000 from being damaged when folded in the reverse direction.

[0060] The rotating arm 925 can include connecting arms (for example, the first connecting arm 9251 and the second connecting arm 9252) and a rotating connection portion 9253. The number of connecting arms can be one or more. For example, the number of connecting arms can be two, namely the first connecting arm 9251 and the second connecting arm 9252 respectively.

[0061] The engaging hole 9254 is installed on the first connecting arm 9251 and is used to engage with the connecting shaft 926. The engaging hole 9255 is installed on the second connecting arm 9252 and is used to engage with the connecting shaft 926.

[0062] The abutting block 9256 is installed on the rotating connection portion 9253, and the abutting block 9256 extends to the side of the first rotating shaft assembly 91. The abutting block 9256 is used to abut against the support plate 82, for example, the first abutting portion 823.

[0063] The connecting shaft 926 is used to be connected to the first buffer arm 221 and the second buffer arm 222 of the connecting member 20. The connecting shaft 926 can be installed in the first strip-shaped through hole 2211 of the first buffer arm 221 and engaged with the first buffer arm 221, and can be installed in the second strip-shaped through hole 2221 of the second buffer arm 222 and engaged with the second buffer arm 222. The connecting shaft 926 is adapted to slide in the through hole 2211 of the first strip stop and the through hole 2221 of the second strip stop respectively. When the first buffer arm 221 and the second buffer arm 222 rotate around the axis of the connecting shaft 926, the connecting shaft 926 can be driven to rotate.

[0064] The link assembly 93 can include two link members, namely the first link member 931 and the second link member 932 respectively. The first link member 931 is located between the first surrounding plate 813 and the first dividing plate 816, and is screwed to the threaded portion 9113 of the rotating shaft 911 and the threaded portion 9213 of the rotating shaft 921. The second link member 932 is located between the first dividing plate 816 and the second dividing plate 817, and is rotatably connected to the sliding portion 9114 of the rotating shaft 911 and the sliding portion 9214 of the rotating shaft 921 respectively. Thereby, the second link member 932 is slid along the axial direction of the rotating shaft 911 by the sliding portion 9114, and the second link member 932 can rotate in the radial direction of the rotating shaft 911. The second link member 932 is slid along the axial direction of the rotating shaft 921 by the sliding portion 9214, and the second link member 932 can rotate in the radial direction of the rotating shaft 921. The portion where the second link member 932 engages with the rotating shaft 911 is located between the spring 913 and the second positioning slider 914. The portion where the second link member 932 engages with the rotating shaft 921 is located between the spring 923 and the second positioning slider 924.

[0065] The portion where the second link member 932 engages with the rotation shaft 911 protrudes toward the second positioning slider 914 and a positioning protrusion is provided, which cooperates with the limiting groove to realize rotation within a limited angular range of the rotation shaft 911, enabling the electronic device 000 to flatten from a half-folded state and preventing the electronic device 000 from being damaged when folded in the reverse direction.

[0066] The portion where the second link member 932 engages with the rotation shaft 921 protrudes toward the second positioning slider 924 and a positioning protrusion is provided, which cooperates with the limiting groove to realize rotation within a limited angular range of the rotation shaft 921, enabling the electronic device 000 to flatten from a half-folded state and preventing the electronic device 000 from being damaged when folded in the reverse direction.

[0067] As can be understood, due to the rotation of the rotating arms 915 and 916, the rotating shafts 911 and 921 rotate simultaneously. As a result, the rotating shaft 911 and the first link member 921 are screwed together and rotate, the rotating shaft 921 and the first link member 931 are screwed together and rotate, and furthermore, the rotating shafts 911 and 921 can move synchronously in the axial direction. The rotating shaft 911 drives the first positioning slider 912 to move toward the second positioning slider 914 side, and further compresses the spring 913. Due to the action of the spring 913, the rotating shaft 911 moves in the reverse direction to maintain the stability of the rotating shaft 911. The rotating shaft 921 drives the first positioning slider 922 to move toward the second positioning slider 924 side, and further compresses the spring 923. Due to the action of the spring 923, the rotating shaft 921 moves in the reverse direction to maintain the stability of the rotating shaft 921 and further improve the stability of the electronic device 000. When the rotating shafts 911 and 921 rotate, the abutting blocks 9156, 9256, 9121, 9221, 9141, and 9241 rotate simultaneously, and further drive the support plate 82 to move to realize the supporting effect on the display module 900. Due to the rotation of the rotating arm 915 and the rotating arm 926, the distance between the rotating arm 915 and the buffer arm changes, whereby the connecting shaft 916 slides within strip-shaped through holes, for example, the first strip-shaped through hole 2211 and the second strip-shaped through hole 2221. The distance between the rotating arm 925 and the buffer arm changes, whereby the connecting shaft 926 slides within strip-shaped through holes, for example, the first strip-shaped through hole 2211 and the second strip-shaped through hole 2221.

[0068] As can be understood, the first positioning slider 922, the spring 923, the second positioning slider 924, and the second link assembly 932 can form an elastic assembly to maintain the stability of the rotating shaft 921. The first positioning slider 912, the spring 913, the second positioning slider 914, and the second link assembly 932 can form an elastic assembly to maintain the stability of the rotating shaft 921. Also, as shown in FIG. 11, the rotating shaft 911 and the rotating shaft 921 are arranged on two opposite sides of the support plate 82.

[0069] Referring to FIG. 1, the display module 900 may be a flexible display screen, which is made of a flexible material and is a variable flexible display device. It can be embedded in the first housing 200 and the second housing 300 for displaying information. The display module 900 may have an integrated structure. Of course, the display module 900 may also be a combination of two flexible display screens, and the two flexible display screens may be embedded in the first housing 200 and the second housing 300 respectively. That is, one of the two flexible display screens is embedded in the first housing 200, and the other one of the two flexible display screens is embedded in the second housing 300.

Here, a folding assembly 500 is installed between the first housing 200 and the second housing 300, so that the first housing 200 and the second housing 300 can be folded with each other. A folding assembly 500 is installed between the second housing 300 and the third housing 400, so that the second housing 300 and the third housing 400 can be folded with each other. The display module 900 is installed on the first housing 200, the second housing 300, the third housing 400 and the folding assembly 500 and is used for displaying information.
