The display module  900  may be folded when the multiple housings  100  are folded, so as to achieve folding the electronic apparatus  000 , facilitating a storage of the electronic apparatus  000 . The electronic apparatus  000  may be used when the multiple housings  100  are unfolded. For example, the display module  900  in  FIG.  1    is located on same sides of the first housing  200  and the second housing  300 , and mounted on both the first housing  200  and the second housing  300 . The display module  900  may be folded in half with the first housing  200  and the second housing  300  being folded towards each other. 
     In addition, terms such as “first”, “second”, and the like, are used herein and hereafter for purposes of description, and are not intended to indicate or imply relative importance or significance or to imply the number of indicated technical features. Thus, the feature defined with “first”, “second”, and the like may include one or more of such a feature. 
     It can be understood that names such as “first housing”, “second housing”, “casing”, “housing”, etc., are interchangeable. For example, the name “first housing” may also be referred to as “second housing”. 
     Specifically, as shown in  FIG.  3    and  FIG.  4   ,  FIG.  4    is a structural schematic view of a housing  100  according to an embodiment of the present disclosure. The number of the housings  100  is two, for example, the housings  100  include the first housing  200  and the second housing  300 . Each of the housings  100  includes a housing body  10  and a connecting member  20 . The housing body  10  is configured to carry the display module  900  and may also be configured to be arranged with the electronic component such as the circuit board, the battery, etc. The connecting member  20  is mounted on the housing body  10  and is configured to be connected to the folding assembly  500  to achieve a connection between the housing  100  and the folding assembly  500 . 
     Specifically, as shown in  FIG.  4   , the housing body  10  may include a base plate  11 , a side wall  12 , and a substrate  13 . The side wall  12  may be arranged on an edge of the base plate  11 , i.e., the side wall  12  may surround, enclose, or be disposed around the edge of the base plate  11 , such that the base plate  11  and the side wall  12  may define an accommodation space configured to accommodate the electronic component such as the camera, the circuit board, the battery, the display module  900 , etc. The substrate  13  is arranged opposite to the base plate  11  and fixedly connected to the side wall  12 . That is, the side wall  12  surrounds or is disposed around a periphery of the substrate  13  and is fixed to the substrate  13  to form a middle frame. The accommodation space may be divided into two parts by the substrate  13  to form a first accommodation space and a second accommodation space. The first accommodation space is located between the base plate  11  and the substrate  13  and configured to receive the electronic component such as the camera, the circuit board, the battery, etc. The second accommodation space is located on a side of the substrate  13  away from the base plate  11  and configured to receive the display module  900 . 
     As shown in  FIG.  4   , the base plate  11  may have a plate-shaped structure. The base plate  11  may be substantially in a rectangular shape or a rounded rectangular shape, etc. A material of the base plate  11  may be a plastic, a glass, a ceramic, a fiber composite, a metal (e.g., a stainless steel, an aluminum, etc.), or other suitable materials or a combination of these materials. In some embodiments, the material of a part of the base plate  11  may be dielectric or other low-conductivity material. In other embodiments, the base plate  11  may be a metal element, or at least some structures of the base plate  11  may be metal elements. 
     The base plate  11  is provided with a mounting portion  14  configured to mount the connecting member  20 . The number of the mounting portions  14  may be multiple. For example, in  FIG.  4   , the number of the mounting portions  14  is two, and the two mounting portions  14  include a first mounting portion  141  and a second mounting portion  142 . Both the first mounting portion  141  and the second mounting portion  142  are provided on a side of an edge of the base plate  11 . The first mounting portion  141  is arranged close to the side wall  12  on a side of the base plate  11 , and the second mounting portion  142  is arranged close to the side wall  12  on an opposite side of base plate  11 . 
     The mounting portion  14  is a hole inwardly recessed from the base plate  11 , and configured to be inserted by the connecting member  20  to fix the connecting member  20 . The connecting member  20  may also be fixed to the mounting portion  14  by means of glue. 
     The side wall  12  is disposed or enclosed around the edge of the base plate  11  and extends towards a same side of the base plate  11 . The side wall  12  is cut or opened on a side of the base plate  11  where the mounting portion  14  is arranged and an opening is defined on the side of the base plate  11  where the mounting portion  14  is arranged, so as to provide an avoiding room or clearance for the folding assembly  500 . That is, side walls  12  are disposed around three edges of the base plate  11 , and a remaining edge of the base plate  11  is arranged without the side wall  12  to define the opening. The mounting portion  14  is disposed adjacent to the remaining edge of the base plate  11 . 
     A portion of the side wall  12  close to a disconnection of the side wall  12  is removed, such that the side wall  12  has a less wall thickness at a position where the portion of the side wall  12  is removed than wall thicknesses at other positions, so as to provide the room for the folding assembly  500 . Understandably, the number of the openings may be more than one, and may be two or three. For example, the side walls  12  in  FIG.  4    may also be disposed on and surround two opposite edges of the base plate  11 , and each of the other two edges of the base plate  11  defines an opening. Of course, in some embodiments, the side walls  12  may also be disposed on two adjacent edges of the base plate  11 , and each of the other two edges of the base plate  11  defines the opening. 
     In an embodiment, the base plate  11  and the side walls  12  are of an integrated structure, and the side wall  12  includes the same material with the base plate  11 . 
     In an embodiment, as shown in  FIG.  4   , the side wall  12  and the substrate  13  are of an integrated structure, and the substrate  13  may be made of the same material as the side wall  12 . In an embodiment, the substrate  13  does not cover the base plate  11  at the opening to provide the room for the folding assembly  500 , such that a part of a structure of the folding assembly  500  is arranged on the base plate  11 . 
     As shown in  FIGS.  4 ,  5  and  6   ,  FIG.  5    is a structural schematic view of a connecting member  20  according to an embodiment of the present disclosure.  FIG.  6    is a structural schematic view of the connecting member  20  according to an embodiment of the present disclosure. The connecting member  20  is configured to be connected to the folding assembly  500 . The number of the connecting members  20  may be multiple. For example, the number of the connecting members  20  may be two, and the two connecting members  20  include a first connecting member  15  and a second connecting member  16 . The first connecting member  15  is mounted on the mounting portion  14 , such as the first mounting portion  141 . The second connecting member  16  is mounted on the mounting portion  14 , such as the second mounting portion  142 . 
     Specifically, the connecting member  20  may include a connecting member body  21  and a buffer arm  22 . The connecting member body  21  is mounted on the mounting portion  14 , such as the first mounting portion  141  or the second mounting portion  142 . The buffer arm  22  is arranged at an opening of the connecting member body  21  and extends towards an outer side of the opening. The buffer arm  22  is connected to the folding assembly  500  in a slide manner. 
     As shown in  FIG.  5   , an insertion post  211  is arranged on a side of the connecting member body  21  facing towards the base plate  11 , extendedly, so as to be inserted into and connected to the mounting portion  14  on the base plate  11 , such as the first mounting portion  141  or the second mounting portion  142 . Understandably, the connecting member body  21  may also be fixedly connected to the mounting portion  14 , such as the first mounting portion  141  or the second mounting portion  142 , by means of gluing, bolting, etc. Of course, the connecting member body  21  and the base plate  11  may be of an integrated structure. 
     As shown in  FIG.  6   , connection walls  212 , such as a first connection wall  213  and a second connection wall  215 , are arranged on a side of the connecting member body  21  away from the base plate  11 . Each of the connection walls  212  extends and is disposed on a corresponding one of both sides substantially parallel to a direction from the connecting member body  21  to the buffer arm  22 . A limiting column  2131  is arranged on a side of the first connection wall  213  facing towards the second connection wall  215 , protrudes from the first connection wall  213 , and extends towards the second connection wall  215 . A limiting column  2151  is arranged on a side of the second connection wall  215  facing towards the first connection wall  213 , protrudes from the second connection wall  215 , and extends towards the first connection wall  213 . The limiting column  2131  and the limiting column  2151  are arranged opposite to each other. A gap between the limiting column  2131  and the connecting member body  21  and a gap between the limiting column  2151  and the connecting member body  21  define a track (such as a first rack  214  and a second rack  216 ), respectively. In this way, it is easier for the limiting column  2131  and the limiting column  2151  to be snapped or engaged with the folding assembly  500 . A part of a structure of the folding assembly  500  may slide on the tracks, such that the folding assembly  500  may rotate around the limiting column  2131  and the limiting column  2151 . In an embodiment, the first connection wall  213  or the second connection wall  215  may be omitted. 
     In an embodiment, a surface of the connecting member body  21  on a side away from the base plate  11  is recessed inwardly and defines a recess  217  to provide the room for the folding assembly  500 . The recess  217  is located between the limiting post  2131  and the limiting post  2151 . In order to facilitate a rotation of the folding assembly  500 , the track may be in a circular arc shape, which also facilitates the folding assembly  500  to rotate out of the track to achieve disassembly of the folding assembly  500  and the connecting member  20 , and also facilitates the folding assembly  500  to rotate into the track to achieve assembly of the folding assembly  500  and the connecting member  20  and subsequent use of the electronic apparatus  000  when folded. 
     As shown in  FIGS.  5  and  6   , the number of the buffer arms  22  may be one or more. For example, the number of buffer arms  22  is two, and the two buffer arms  22  include a first buffer arm  221  and a second buffer arm  222 . A gap is defined between two adjacent buffer arms  22  to provide the room for the folding assembly  500 . For example, a gap  23  is defined between the first buffer arm  221  and the second buffer arm  222 . Each buffer arm  22  defines a strip through hole, and the strip through hole defined in one buffer arm  22  is arranged opposite to the strip through hole defined in the other buffer arm  22 , such that a part of the structure of the folding assembly  500  may pass through each strip through hole together and slide in a length direction of each strip through hole. For example, the first buffer arm  221  defines a first strip through hole  2211 , and the second buffer arm  222  defines a second strip through hole  2221 . 
     As shown in  FIG.  7   ,  FIG.  7    is a structural schematic view of a folding assembly  500  according to an embodiment of the present disclosure. The folding assembly  500  may include pallets  30  (e.g., a first pallet  31 , and a second pallet  32 ), a supporting bracket  40 , and a rotating shaft module  50  (e.g., a first rotating shaft module  60 , and a second rotating shaft module  70 ). Specifically, the supporting bracket  40  is arranged between two adjacent housings  100 . For example, the supporting bracket  40  is arranged between the first housing  200  and the second housing  300 . The first rotating shaft module  60  and the second rotating shaft module  70  of the rotating shaft module  50  are located at both ends of the supporting bracket  40 , respectively. That is, the first rotating shaft module  60  is located at one end of the supporting bracket  40 , and the second rotating shaft module  70  is located at the other end of the supporting bracket  40 . The first rotating shaft module  60  and the second rotating shaft module  70  are fixedly connected to the supporting bracket  40 . The rotating shaft module  50  is arranged between two adjacent housings  100  and connected to the two adjacent housings  100 , such that the two adjacent housings  100  may be folded when the rotating shaft module  50  is rotated. For example, both the first rotating shaft module  60  and the second rotating shaft module  70  may allow the first housing  200  and the second housing  300  to be connected together. The first pallet  31  and the second pallet  32  of the pallets  30  are arranged substantially symmetrically on two opposite sides of the supporting bracket  40 , respectively. That is, the first pallet  31  is arranged on a first side of the supporting bracket  40 , and the second pallet  32  is arranged on a second side opposite to the first side of the supporting bracket  40 . The first pallet  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 second pallet  32  is also rotatably connected to the first rotating shaft module  60  and the second rotating shaft module  70 , respectively. The first pallet  31  and the second pallet  32  may be carried on the supporting bracket  40  and configured to carry the display module  900 . The first pallet  31 , the second pallet  32 , and the display module  900  are fixed together for protecting the display module  900  and reducing a possibility of the display module  900  being bent and damaged when the folding assembly  500  is folded. 
     As shown in  FIGS.  7 ,  8 , and  9   ,  FIG.  8    is a structural schematic view of a pallet  30  from a perspective according to an embodiment of the present disclosure.  FIG.  9    is a structural schematic view of the pallet  30  from another perspective according to an embodiment of the present disclosure. The number of the pallets  30  may be multiple. For example, the pallets  30  may include two pallets, i.e., the first pallet  31  and the second pallet  32 . The first pallet  31  and the second pallet  32  are arranged substantially symmetrically on two sides of the supporting bracket  40 , respectively. That is, the first pallet  31  is arranged on the first side of the supporting bracket  40 , and the second pallet  32  is arranged on the second side opposite to the first side of the supporting bracket  40 . The first pallet  31  and the second pallet  32  are configured to be bonded or attached to the display module  900  and carry the display module  900  during folding or unfolding of the housing assembly  100 , such that the display module  900  may be bent and folded and a surface of the display module  900  tends to be flat when the display module  900  is unfolded. 
     Specifically, the pallet  30  may include a connection plate  33 . The connection plate  33  may be a strip-shaped plate structure and configured to be bonded or attached to the display module  900 . Each of two ends of a side edge of the connection plate  33  is provided with a connection portion, such as a first connection portion  34  or a second connection portion  35 , and the connection portion is configured to be rotatably connected to the connecting member  20 .

The connecting shaft  926  may be arranged in the first strip through hole  2211  of the first buffer arm  221  and engaged with the first buffer arm  221 , and arranged in the second strip through hole  2221  of the second buffer arm  222  and engaged with the second buffer arm  222 , such that the connecting shaft  926  may slide in the first strip through hole  2211  and the second strip through hole  2221 , respectively. In this way, the connecting shaft  926  may be driven to rotate when the first buffer arm  221  and the second buffer arm  222  rotate around an axis of the connecting shaft  926 . 
     The connection assembly  93  may include two connecting members, i.e., a first connecting member  931  and a second connecting member  932 , respectively. The first connecting member  931  is located between the second surrounding plate  813  and the first separating plate  816 , and threadedly connected to the threaded portion  9113  of the rotating shaft  911  and the threaded portion  9213  of the rotating shaft  921 . The second connecting member  932  is located between the first separating plate  816  and the second separating plate  817 , and rotatably connected to the sliding portion  9114  of the rotating shaft  911  and the sliding portion  9214  of the rotating shaft  921 , respectively, such that the second connecting member  932  slides on the sliding portion  9114  in the axial direction of the rotating shaft  911  and rotate in the radial direction of the rotating shaft  911 , and slides on the sliding portion  9214  in an axial direction of the rotating shaft  921  and rotate in an radial direction of the rotating shaft  921 . A portion of the second connecting member  932  engaged with the rotating shaft  911  is located between the spring  913  and the second limiting slider  914 . A portion of the second connecting member  932  engaged with the rotating shaft  921  is located between the spring  923  and the second limiting slider  924 . 
     The portion of the second connecting member  932  engaged with the rotating shaft  911  protrudes towards the second limiting slider  914  to form a limiting protrusion, so as to cooperate with the limiting groove and achieve the rotating shaft  921  rotating within the limited angle range. In this way, the electronic apparatus  000  may be flattened from the folded state, and the possibility of damaging the electronic apparatus  000  caused by folding backwards may be reduced. 
     The portion of the second connecting member  932  engaged with the rotating shaft  921  protrudes towards the second limiting slider  924  to form a limiting protrusion, so as to cooperate with the limiting groove and achieve the rotating shaft  921  rotating within the limited angle range. In this way, the electronic apparatus  000  may be flattened from the folded state, and the possibility of damaging the electronic apparatus  000  caused by folding backwards may be reduced. 
     It can be understood that, due to rotation of the rotating arm  915  and the rotating arm  925 , the rotating shaft  911  and the rotating shaft  921  may rotate simultaneously, such that the rotating shaft  911  rotates threadedly with the first connecting member  931  and the rotating shaft  921  rotates threadedly with the first connecting member  931 , which in turn allows the rotating shaft  911  and the rotating shaft  921  to move simultaneously in their axial directions. The rotating shaft  911  drives the first limiting slider  912  to move towards the second limiting slider  914 , such that the spring  913  is compressed. Under the action of the spring  913 , the rotating shaft  911  may move in an opposite direction, so as to keep the rotating shaft  911  stable. The rotating shaft  921  drives the first limiting slider  922  to move towards the second limiting slider  924 , such that the spring  923  is compressed. Under the action of the spring  923 , the rotating shaft  921  may move in an opposite direction, so as to keep the rotating shaft  921  stable and improve stability of the electronic apparatus  000 . When the rotating shaft  911  and the rotating shaft  921  are rotated, the abutting member  9156 , the abutting member  9256 , the abutting member  9121 , the abutting member  9221 , the abutting member  9141 , and the abutting member  9241  are rotated simultaneously, which in turn drives the supporting member  82  to move, thereby adjusting the distance between the supporting member  82  and the mounting plate  811  and supporting the display module  900 . Under the rotation of the rotating arm  915  and the rotating arm  925 , a distance between the rotating arm  915  and the buffer arm may change, such that the connecting shaft  916  slides in the strip through holes such as the first strip through hole  2211  and the second strip through hole  2221 . A distance between the rotating arm  925  and the buffer arm may change, such that the connecting shaft  926  slides in the strip through holes such as the first strip through hole  2211  and the second strip through hole  2221 . 
     Understandably, the first limiting slider  922 , the spring  923 , the second limiting slider  924 , and the second connecting member  932  may be assembled as a resilient assembly (also called as “elastic assembly”) to keep the rotating shaft  921  stable. The first limiting slider  912 , the spring  913 , the second limiting slider  914 , and the second connecting member  932  may be assembled as a resilient assembly (also called as “elastic assembly”) to keep the rotating shaft  911  stable. Furthermore, the rotating shaft  911  and the rotating shaft  921  are disposed at two opposite sides of the supporting member  82 , as shown in  FIG.  11   . 
     As shown in  FIG.  1   , the display module  900  may be a flexible display, and may be a variable and bendable display device made of a soft or flexible material. The display module  900  may be embedded in the first housing  200  and the second housing  300  and configured to display information. The display module  900  may be an integrated structure. Of course, the display module  900  may also be an assembly of two flexible displays, and the two flexible displays are embedded in the first housing  200  and the second housing  300 , respectively. That is, one of the two flexible displays is embedded in the first housing  200 , and the other one of the two flexible displays is embedded in the second housing  300 .

The electronic apparatus  000  may include the first housing  200 , the second housing  300 , a third housing  400 , folding assemblies  500 , and a display module  900 . One of the folding assembly  500  is arranged between the first housing  200  and the second housing  300 , such that the first housing  200  may be foldable relative to the second housing  300 . Another of the folding assemblies  500  is arranged between the second housing  300  and the third housing  400 , such that the second housing  300  may be foldable relative to the third housing  400 .
