     BACKGROUND 
     Technical Field 
     The disclosure relates to an electronic device, and more particularly to an electronic device with bodies pivotally rotated relative to each other. 
     Description of Related Art 
     With the popularization and the development of notebook computers, consumers have increasing demand for convenience and a variety of functions. In some notebook computers, two bodies are provided with display panels in the form of dual screens. The two bodies can be rotated 180 degrees relative to each other to be flattened, and the two bodies can be rotated 360 degrees relative to each other to be a tablet operation mode. To make it possible for the relative positions of the two display panels to be changed in response to different rotating angles of the two bodies, a linkage structure for driving the display panel to move relative to the body is added to the hinge structure of some notebook computers. However, integrating the linkage structure into the hinge structure as described above causes the hinge structure subjected to additional force when in operation, and the linkage structure is likely to interfere with the structure and the operation of the hinge structure. 
     SUMMARY 
     The disclosure provides an electronic device capable of preventing adverse effects on a hinge structure caused by the configuration of a linkage structure. 
     The electronic device of the disclosure includes two bodies, at least one hinge structure, a functional assembly and at least one linkage structure. The two bodies are pivotally connected to each other through the hinge structure. The functional assembly is movably disposed on one of the two bodies. The linkage structure is connected between the two bodies, and the functional assembly is connected to the linkage structure. The linkage structure is adapted to drive the functional assembly to move relative to the corresponding body as the two bodies are rotated relative to each other. 
     In an embodiment of the disclosure, the linkage structure includes a first pivot assembly and two first shafts. The two bodies are respectively pivotally connected to the first pivot assembly through the two first shafts. The hinge structure includes a second pivot assembly and two second shafts. The two second shafts are pivotally connected to the second pivot assembly and respectively connected to the two bodies, and the two first shafts are separated from the two second shafts. 
     In an embodiment of the disclosure, the electronic device further includes another functional assembly. The another functional assembly is movably disposed on the other of the two bodies, the another functional assembly is connected to the linkage structure, and the linkage structure is adapted to drive the another functional assembly to move relative to the other corresponding body as the two bodies are rotated relative to each other. 
     In an embodiment of the disclosure, the linkage structure includes a first pivot assembly, two first shafts, and two linkage assemblies. The two linkage assemblies are respectively pivotally connected to the first pivot assembly through the two first shafts and respectively connected to the two bodies and the two functional assemblies. 
     In an embodiment of the disclosure, each of the linkage assemblies includes a first frame and a second frame. The first frame is fixed on the corresponding body and connected to the corresponding first shaft. The second frame is slidably disposed on the first frame along a first direction perpendicular to an axial direction of the corresponding first shaft and parallel to the corresponding display surface of the functional assembly and connected to the corresponding functional assembly. The first pivot assembly is adapted to drive the corresponding second frame to slide along the first direction relative to the corresponding first frame body along as the two bodies are rotated relative to each other, so that each of the corresponding functional assemblies driven by the second frame relative to the corresponding body is translated along the first direction. 
     In an embodiment of the disclosure, each of the linkage assemblies further includes a sliding element and a connecting rod. The sliding element is slidably disposed on the first frame along a second direction perpendicular to the first direction and parallel to a corresponding display surface of the functional assembly. The connecting rod is connected between the sliding element and the second frame. The first pivot assembly is adapted to drive the sliding element to slide relative to the first frame along the second direction, so that the sliding element drives the second frame to slide relative to the first frame along the first direction through the connecting rod. 
     In an embodiment of the disclosure, the first pivot assembly or the two first shafts include two guiding parts. The two guiding parts respectively correspond to the two sliding elements, and as each of the linkage assemblies is rotated relative to the first pivot assembly, the corresponding sliding element is guided by the corresponding guiding part to slide relative to the first frame along the second direction. 
     In an embodiment of the disclosure, each of the linkage assemblies further includes a third frame. The third frame is slidably disposed on the second frame along a third direction perpendicular to the first direction and perpendicular to a display surface of the corresponding functional assembly. Each of the functional assemblies is fixed on the corresponding third frame. When the third frame slides along the first direction with the second frame, the third frame is driven to slide along the third direction to drive the corresponding functional assembly relative to the corresponding body to move up and down along the third direction. 
     In an embodiment of the disclosure, each of the bodies includes a guiding structure corresponding to the third frame. When the third frame slides along the first direction with the second frame, the third frame is guided by the guiding structure to slide along the third direction. 
     In an embodiment of the disclosure, one end of each of the functional assemblies is fixed on the corresponding third frame, and another end of each of the functional assemblies is connected to the corresponding body in a translational and vertically movable manner, so that each of the functional assemblies in a collective manner is adapted to move up and down relative to the corresponding body as the corresponding third frame moves. 
     In an embodiment of the disclosure, one end of each of the functional assemblies is fixed on the corresponding third frame, and another end of each of the functional assemblies is connected to the corresponding body in a translational and movable manner, so that each of the functional assemblies in a collective manner is adapted to incline relative to the corresponding body as the corresponding third frame moves. 
     In an embodiment of the disclosure, when the two bodies are unfolded relative to each other from a closed state to a state with a first unfolding angle, the linkage structure does not drive each of the functional assemblies to move relative to the corresponding body. When the two bodies with the first unfolding angle continue to be unfolded relative to each other to a state with a second unfolding angle, the linkage structure drives each of the functional assemblies to move up and translate relative to the corresponding body so that the edges of the two functional assemblies are close to each other. When the two bodies with the second unfolding angle continue to be unfolded relative to each other to a state with a third unfolding angle, the linkage structure drives each of the functional assemblies to translate relative to the corresponding body so that the edges of the two functional assemblies are close to each other. When the two bodies with the third unfolding angle continue to be unfolded relative to each other to a state with a fourth unfolding angle, the linkage structure drives each of the functional assemblies to move down and translate relative to the corresponding body so that the edges of the two functional assemblies lean against each other. When the two bodies with the fourth unfolding angle continue to be unfolded relative to each other to a state with a fifth unfolding angle, the linkage structure drives each of the functional assemblies to translate relative to the corresponding body so that the edges of the two functional assemblies are apart from each other. When the two bodies with the fifth unfolding angle continue to be unfolded relative to each other to a state with a sixth unfolding angle, the linkage structure does not drive each of the functional assemblies to move relative to the corresponding body. 
     In an embodiment of the disclosure, the first unfolding angle, the second unfolding angle, the third unfolding angle, the fourth unfolding angle, the fifth unfolding angle, and the sixth unfolding angle are 20 degrees, 90 degrees, and 150 degrees, 180 degrees, 210 degrees, and 360 degrees respectively. 
     In an embodiment of the disclosure, when the two bodies are unfolded relative to each other from a closed state to a state with a first unfolding angle, the linkage structure does not drive each of the functional assemblies to move relative to the corresponding body. When the two bodies with the first unfolding angle continue to be unfolded relative to each other to a state with a second unfolding angle, the linkage structure drives each of the functional assemblies to move up and translate relative to the corresponding body so that the edges of the two functional assemblies are close to each other. When the two bodies with the second unfolding angle continue to be unfolded relative to each other to a state with a third unfolding angle, the linkage structure drives each of the functional assemblies to translate relative to the corresponding body so that the edges of the two functional assemblies are close to each other. When the two bodies with the third unfolding angle continue to be unfolded relative to each other to a state with a fourth unfolding angle, the linkage structure drives each of the functional assemblies to translate relative to the corresponding body so that the edges of the two functional assemblies lean against each other. When the two bodies with the fourth unfolding angle continue to be unfolded relative to each other to a state with a fifth unfolding angle, the linkage structure drives each of the functional assemblies to move down and translate relative to the corresponding body so that the edges of the two functional assemblies are apart from each other. When the two bodies with the fifth unfolding angle continue to be unfolded relative to each other to a state with a sixth unfolding angle, the linkage structure does not drive each of the functional assemblies to move relative to the corresponding body. 
     In an embodiment of the disclosure, the first unfolding angle, the second unfolding angle, the third unfolding angle, the fourth unfolding angle, the fifth unfolding angle, and the sixth unfolding angle are 20 degrees, 90 degrees, 150 degrees, 180 degrees, 210 degrees, and 360 degrees respectively. 
     In an embodiment of the disclosure, the electronic device further includes at least one cover. The cover is disposed between the hinge structure and the linkage structure and covers part of the hinge structure and part of the linkage structure. 
     In an embodiment of the disclosure, the cover includes a retaining wall, and the retaining wall separates the hinge structure and linkage structure. 
     In an embodiment of the disclosure, the electronic device further includes a cover. The number of the linkage structure is two, and the cover is disposed between the two linkage structures and covers part of each of the linkage structures. 
     In an embodiment of the disclosure, the cover includes a retaining wall, and the retaining wall separates the two linkage structures. 
     Based on the above, in the electronic device of the disclosure, the linkage structure is not a structure included in the hinge structure, so the linkage structure can be independently disposed and apart from the hinge structure instead of being integrated into the hinge structure. Accordingly, when in operation, the hinge structure is not subjected to additional force caused by the configuration of the linkage structure, and the linkage structure disposed independently does not interfere with the structure and the operation of the hinge structure.

     DESCRIPTION OF THE EMBODIMENTS 
       FIG. 1  is a perspective view of an electronic device according to an embodiment of the disclosure. Referring to  FIG. 1 , an electronic device  100  in the embodiment includes a body  110   a , a body  110   b , at least one hinge structure  120  (two hinge structures are shown), a functional assembly  130   a , a functional assembly  130   b , and at least one linkage structure  140  (two linkage structures  140  are shown). The two bodies  110   a  and  110   b  are pivotally connected to each other through the two hinge structures  120 . The two functional assemblies  130   a  and  130   b  are, for example, display panels and are respectively movably disposed on the two bodies  110   a  and  110   b . Each of the linkage structures  140  is connected between the two bodies  110   a  and  110   b  and separated from each of the hinge structures  120 , and each of the functional assemblies  130   a  and  130   b  is connected to the two linkage structures  140 . In other embodiments, the functional assemblies  130   a  and  130   b  may be a display panel and an input device (e.g., a keyboard or a touch pad), respectively, or may be other types of elements, respectively. The disclosure is not limited thereto. In other words, the two functional assemblies of the disclosure may be the same or different from each other. For example, they may be both or respectively a display panel, a touch-sensitive display panel, a keyboard, a touch pad, a speaker, a combination of a keyboard and a touch pad, a combination of a display and an input device, etc. The disclosure is not limited thereto. In addition, each of the functional assemblies may be respectively electrically connected to at least one of the two bodies, and the connection is not limited to a wired form or a wireless form. Furthermore, in some embodiments, the electronic device  100  may include one of the functional assemblies  130   a  and  130   b  but may not include the other of the functional assemblies  130   a  and  130   b.    
       FIG. 2A  to  FIG. 2C  illustrate the two bodies of  FIG. 1  rotated relative to each other. The two bodies  110   a  and  110   b  are rotated relative to each other from a closed state shown in  FIG. 1  to an unfolded state shown in  FIG. 2A , from the unfolded state shown in  FIG. 2A  to a flattened state shown in  FIG. 2B , and from the flattened state shown in  FIG. 2B  to a reflexed state shown in  FIG. 2C  through the pivotal rotation of each of the hinge structures  120 . In addition, each of the linkage structures  140  drives each of the functional assemblies  130   a  and  130   b  to move relative to the corresponding bodies  110   a  and  110   b  as the two bodies are rotated relative to each other. 
     Based on the above, each of the linkage structures  140  is not a structure included in the hinge structure  120 , so the linkage structure  140  may be independently disposed and apart from the hinge structure  120  instead of being integrated into the hinge structure  120 . Accordingly, when in operation, the hinge structure  120  is not subjected to additional force caused by the configuration of the linkage structure  140 , and the linkage structure  140  disposed independently does not interfere with the structure and the operation of the hinge structure  120 . 
       FIG. 3A  to  FIG. 3G  are schematic views of the rotating process of the electronic device in  FIG. 1 . For example, when the two bodies  110   a  and  110   b  are unfolded relative to each other from the closed state shown in  FIG. 3A  to the state shown in  FIG. 3B  and have a first unfolding angle A 1  (e.g., 20 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) does not drive each of the functional assemblies  130   a  and  130   b  to move relative to the corresponding bodies  110   a  and  110   b . When the two bodies  110   a  and  110   b  with the first unfolding angle A 1  continue to be unfolded relative to each other from the state shown in  FIG. 3B  to the state shown in  FIG. 3C  and have a second unfolding angle A 2  (e.g., 90 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to move up and translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are close to each other. When the two bodies  110   a  and  110   b  with the second unfolding angle A 2  continue to be unfolded relative to each other from the state shown in  FIG. 3C  to the state shown in  FIG. 3D  and have a third unfolding angle A 3  (e.g., 150 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are close to each other. When the two bodies  110   a  and  110   b  with the third unfolding angle A 3  continue to be unfolded relative to each other from the state shown in  FIG. 3D  to the state shown in  FIG. 3E  and have a fourth unfolding angle A 4  (e.g., 180 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to move down and translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  lean against each other. When the two bodies  110   a  and  110   b  with the fourth unfolding angle A 4  continue to be unfolded relative to each other from the state shown in  FIG. 3E  to the state shown in  FIG. 3F  and have a fifth unfolding angle A 5  (e.g., 210 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are apart from each other. When the two bodies  110   a  and  110   b  with the fifth unfolding angle A 5  continue to be unfolded relative to each other from the state shown in  FIG. 3F  to the state shown in  FIG. 3G  and have a sixth unfolding angle A 6  (e.g., 360 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) does not drive each of the functional assemblies  130   a  and  130   b  to move relative to the corresponding bodies  110   a  and  110   b.    
     Note that the operation flow shown in  FIG. 3A  to  FIG. 3G  is merely illustrative, and the disclosure does not limit the timing for each of the functional assemblies  130   a  and  130   b  to move up, move down, and translate. Another operation flow is described below.  FIG. 4A  to  FIG. 4G  are schematic views of the rotating process of an electronic device according to another embodiment of the disclosure. When the two bodies  110   a  and  110   b  are unfolded relative to each other from the closed state shown in  FIG. 4A  to the state shown in  FIG. 4B  and have the first unfolding angle A 1  (e.g., 20 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) does not drive each of the functional assemblies  130   a  and  130   b  to move relative to the corresponding bodies  110   a  and  110   b . When the two bodies  110   a  and  110   b  with the first unfolding angle A 1  continue to be unfolded relative to each other from the state shown in  FIG. 4B  to the state shown in  FIG. 4C  and have the second unfolding angle A 2  (e.g., 90 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to move up and translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are close to each other. When the two bodies  110   a  and  110   b  with the second unfolding angle A 2  continue to be unfolded relative to each other from the state shown in  FIG. 4C  to the state shown in  FIG. 4D  and have the third unfolding angle A 3  (e.g., 150 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are close to each other. When the two bodies  110   a  and  110   b  with the third unfolding angle A 3  continue to be unfolded relative to each other from the state shown in  FIG. 4D  to the state shown in  FIG. 4E  and have the fourth unfolding angle A 4  (e.g., 180 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  lean against each other. When the two bodies  110   a  and  110   b  with the fourth unfolding angle A 4  continue to be unfolded relative to each other from the state shown in  FIG. 4E  to the state shown in  FIG. 4F  and have the fifth unfolding angle A 5  (e.g., 210 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) drives each of the functional assemblies  130   a  and  130   b  to move down and translate relative to the corresponding bodies  110   a  and  110   b  so that the edges of the two functional assemblies  130   a  and  130   b  are apart from each other. When the two bodies  110   a  and  110   b  with the fifth unfolding angle A 5  continue to be unfolded relative to each other from the state shown in  FIG. 4F  to the state shown in  FIG. 4G  and have the sixth unfolding angle A 6  (e.g., 360 degrees), each of the linkage structures  140  (shown in  FIG. 1 ) does not drive each of the functional assemblies  130   a  and  130   b  to move relative to the corresponding bodies  110   a  and  110   b.    
     In the embodiment, the hinge structure  120  is, for example, in the form of dual shafts, the linkage structure  140  is also, for example, in the form of dual shafts, and the shaft of the linkage structure  140  and the shaft of the hinge structure  120  are separated from each other. That is, the linkage structure  140  and the hinge structure  120  do not share a shaft, so that the linkage structure  140  is independently disposed and apart from the hinge structure  120  as described above. Accordingly, when in operation, the hinge structure  120  is not subjected to additional force caused by the configuration of the linkage structure  140 , and the linkage structure  140  disposed independently does not interfere with the structure and the operation of the hinge structure  120 . This is illustrated with reference to the drawings below. 
       FIG. 5  is a perspective view of the linkage structure, the hinge structure, and the cover of  FIG. 1 .  FIG. 6  is an exploded view of the linkage structure, the hinge structure, and the cover of  FIG. 5 .  FIG. 7  is a rear view of the linkage structure, the hinge structure, and the cover of  FIG. 5 . Referring to  FIG. 5  to  FIG. 7 , the linkage structure  140  in the embodiment includes a first pivot assembly  142  and two first shafts  144 . The two bodies  110   a  and  110   b  (shown in  FIG. 1 ) respectively are pivotally connected to the first pivot assembly  142  through the two first shafts  144 . The hinge structure  120  includes a second pivot assembly  122  and two second shafts  124 . The two second shafts  124  are pivotally connected to the second pivot assembly  122  and are respectively connected to the two bodies  110   a  and  110   b  (shown in  FIG. 1 ). In addition, the two first shafts  144  of the linkage structure  140  are separated from the two second shafts  124  of the hinge structure  120 . 
     The electronic device  100  in the embodiment as shown in  FIG. 5  to  FIG. 7  further includes at least one cover  150  (two covers  150  are shown in  FIG. 1 ). The cover  150  is disposed between the hinge structure  120  and the linkage structure  140  and covers part of the hinge structure  120  and part of the linkage structure  140 . The cover  150  has a retaining wall  152  (shown in  FIG. 7 ). The retaining wall  152  separates the hinge structure  120  and the linkage structure  140 , so that the hinge structure  120  and the linkage structure  140  maintain a predetermined relative position after being assembled with the cover  150 . In addition, the cover  150  may have a fastening hole  152   a  in the retaining wall  152  for the hinge structure  120  and the linkage structure  140  to be fastened. 
     The configuration and the operation of the linkage structure  140  in the embodiment are described in detail below.  FIG. 8  is a perspective view of the linkage structure of  FIG. 6 . Referring to  FIG. 5 ,  FIG. 6 , and  FIG. 8 , the linkage structure  140  in the embodiment further includes two linkage assemblies  146 , and the two first shafts  144  are respectively connected to the two bodies  110   a  and  110   b  (shown in  FIG. 1 ) and the two functional assemblies  130   a  and  130   b  (shown in  FIG. 1 ) through the two linkage assemblies  146 . Specifically, each of the linkage assemblies  146  includes a first frame  146   a  and a second frame  146   b . The first frame  146   a  is fixed on the corresponding body  110   a  (or  110   b ) and connected to the corresponding first shaft  144 . The second frame  146   b  is slidably disposed in a sliding groove  146   a   1  of the first frame  146   a  along a first direction D 1  perpendicular to the axial direction of the corresponding first shaft  144  and parallel to the display surface of the corresponding functional assembly  130   a  (or  130   b ) and connected to the corresponding functional assembly  110   a  (or  110   b ). The first pivot assembly  142  is adapted to drive the corresponding second frame  146   b  to slide along the first direction D 1  relative to the corresponding first frame  146   a  as the two bodies  110   a  and  110   b  are rotated relative to each other, so that each of the second frames  146   b  drives the corresponding functional assembly  130   a  (or  130   b ) to translate along the first direction D 1  relative to the corresponding body  110   a  (or  110   b ). 
     More specifically, each of the linkage assemblies  146  further includes a sliding element  146   c  and a connecting rod  146   d . The sliding element  146   c  is slidably disposed on the first frame  146   a  along a second direction D 2  perpendicular to the first direction D 1  and parallel to the display surface of the corresponding functional assembly  130   a  (or  130   b ). The connecting rod  146   d  is connected between the sliding element  146   c  and the second frame  146   b . The first pivot assembly  142  has two guiding parts  142   a , and the two guiding parts  142   a  respectively correspond to the two sliding elements  146   c . As each of the linkage assemblies  146  is rotated relative to the first pivot assembly  142 , the sliding element  146   c  guided by the guiding part  142   a  of the first pivot assembly  142  is driven by the first pivot assembly  142  to slide along the second direction D 2  relative to the first frame  146   a , so that the sliding element  146   c  drives the second frame  146   b  to slide along the first direction D 1  relative to the first frame  146   a  through the connecting rod  146   d . Accordingly, the functional assembly  130   a  (or  130   b ) connected to the second frame  146   b  may be translated relative to the body  110   a  (or  110   b ) as shown in the operation flow of  FIG. 3A  to  FIG. 3G  or the operation flow of  FIG. 4A  to  FIG. 4G . 
     In the embodiment, each of the guiding parts  142   a  has, for example, a guiding groove  142   a   1 . Each of the sliding elements  146   c  has, for example, a protrusion, and the protrusion extends into the guiding groove  142   a   1 . The guiding groove  142   a   1  includes an inclined section and guides each of the sliding elements  146   c  to slide along the second direction D 2  as each of the linkage assemblies  146  is rotated relative to the first pivot assembly  142  as described above. In other embodiments, by changing the extending mode of the guiding groove  142   a   1 , the timing for the functional assemblies  130   a  and  130   b  to be translated may be changed accordingly. The disclosure is not limited thereto. In addition, in other embodiments, each of the guiding parts  142   a  may guide the sliding element  146   c  to slide through other suitable structures, and the disclosure is not limited thereto. In addition, in the embodiment, one end of the connecting rod  146   d  is pivotally connected to the sliding element  146   c , and another end of the connecting rod  146   d  is slidably disposed in an arc-shaped groove  146   a   2  of the first frame  146   a  and is rotatably and slidably connected to the second frame  146   b , so that the sliding element  146   c  sliding along the second direction D 2  is capable of driving the second frame  146   b  to slide along the first direction D 1  through the connecting rod  146   d . In other embodiments, the second frame  146   b  may be driven by other appropriate linkage assemblies, and the disclosure is not limited thereto. 
       FIG. 9  is a perspective view of part of the linkage structure of  FIG. 8 .  FIG. 10  is an exploded view of the linkage structure of  FIG. 9 . Referring to  FIG. 8  to  FIG. 10 , each of the linkage assemblies  146  in the embodiment further includes a third frame  146   e . The third frame  146   e  is slidably disposed on a sliding groove  146   b   1  of the second frame  146   b  along a third direction D 3  perpendicular to the first direction D 1  and perpendicular to the display surface of the corresponding functional assembly  130   a  (or  130   b ) through a pin P, and each of the functional assemblies  130   a  and  130   b  is fixed on the corresponding third frame  146   e . In addition, each of the bodies  110   a  and  110   b  has a guiding structure  112 , and the guiding structure  112  corresponds to the third frame  146   e . In addition to being slidably disposed in the sliding groove  146   b   1  of the second frame  146   b  through the pin P as described above, the third frame  146   e  is also slidably disposed in a guiding groove  112   a  of the guiding structure  112  through the pin P. When the third frame  146   e  slides along the first direction D 1  with the second frame  146   b , the third frame  146   e  guided by the inclined section of the guiding groove  112   a  is driven to slide along the third direction D 3  to drive the corresponding functional assemblies  130   a  and  130   b  to move up and down along the third direction D 3  relative to the corresponding bodies  110   a  and  110   b  as shown in the operation flow of  FIG. 3A  to  FIG. 3G  or the operation flow of  FIG. 4A  to  FIG. 4G . In other embodiments, by changing the extending mode of the guiding groove  112   a , the timing for the functional assemblies  130   a  and  130   b  to move up and down may be changed accordingly, and the disclosure is not limited thereto. 
       FIG. 11  illustrates how one end of the functional assembly of  FIG. 2A  is connected to the body.  FIG. 11  corresponds to the position  130   a   2  shown in  FIG. 2A , and  FIG. 8  corresponds to the position  130   a   1  shown in  FIG. 2A . In the embodiment, one end of each of the functional assemblies  130   a  and  130   b  is fixed on the corresponding third frame  146   e  (shown in  FIG. 8 ), and another end of each of the functional assemblies  130   a  and  130   b  is connected to the corresponding bodies  110   a  and  110   b  in a translational and vertically movable manner as shown in  FIG. 11 . Accordingly, each of the functional assemblies  130   a  and  130   b  in a collective manner is adapted to move up and down relative to the corresponding bodies  110   a  and  110   b  with the movement of the corresponding third frame  146   e . In the embodiment, the body  110   a  may have a guiding structure  114  at the position  130   a   2  of  FIG. 2A  as shown in  FIG. 11 . The functional assembly  130   a  (not shown in  FIG. 11 ) is slidably disposed in a guiding groove  114   a  of the guiding structure  114  through a pin  132   a  of a connecting element  132 , so that one end of the functional assembly  130   a  guided by the inclined section of the guiding groove  114   a  is driven to move up and down along the third direction D 3  as described above. In other embodiments, other guiding structures may be adapted to replace the guiding structure  114  of  FIG. 11 , so that the functional assembly  130   a  has a different operation mode, which is illustrated with reference to drawings below. 
       FIG. 12  illustrates how one end of the functional assembly is connected to the body according to another embodiment of the disclosure. The difference between the embodiment shown in  FIG. 12  and the embodiment shown in  FIG. 11  is that a guiding groove  114   a ′ of the guiding structure  114 ′ is a linear guiding groove without inclined sections, so that the one end of the functional assembly  130   a  (not shown in  FIG. 12 ) may be connected to the body  110   a  in a transitional and rotatable manner through a pin  132   a ′ of a connecting element  132 ′, and in this way the functional assembly  130   a  in a collective manner is adapted to incline relative to the corresponding body  110   a  as the corresponding third frame  146   e  (shown in  FIG. 8 ) moves up and down. 
     The disclosure does not limit the quantity of the linkage structure  140  and the relative position relationship between the linkage structure  140  and the hinge structure  120 , which is illustrated with reference to drawings below. 
       FIG. 13  is a perspective view of an electronic device according to another embodiment of the disclosure.  FIG. 14  is a perspective view of the linkage structure and the cover of  FIG. 13 .  FIG. 15  is an exploded view of the linkage structure and the cover of  FIG. 14 . The difference between the embodiment shown in  FIG. 13  to  FIG. 15  and the embodiment shown in  FIG. 1  is that the electronic device  100 A of  FIG. 13  includes two covers  1501  and a cover  1502 . The cover  1502  is disposed between two linkage structures  140 A and covers part of each of the linkage structures  140 A. The two covers  1501  respectively cover part of the two hinge structures  120 A.  FIG. 16  is a rear view of the linkage structure and the cover of  FIG. 14 . As shown in  FIG. 16 , the cover  1502  has a retaining wall  1502   a  separating the two linkage structures  140 A, so that the two linkage structures  140 A maintain a predetermined relative position after being assembled with the cover  1502 . In addition, the cover  1502  may have a fastening hole  1502   b  in the retaining wall  1502   a  for the two linkage structures  140  to be fastened. The operation modes of the hinge structure  120 A and the linkage structure  140 A are the same or similar to those of the hinge structure  120  and the linkage structure  140  in the foregoing embodiment, and is not iterated here. 
       FIG. 17  is a perspective view of an electronic device according to another embodiment of the disclosure. The difference between the embodiment shown in  FIG. 17  and the embodiment shown in  FIG. 1  is that an electronic device  100 B of  FIG. 17  includes two covers  1503  and a cover  1504 , and the cover  1503  covers part of two hinge structures  120 B, respectively. The number of the linkage structure  140  is one and it is partially covered by the cover  1504 . The operation modes of the hinge structure  120 B and the linkage structure  140 B are the same or similar to those of the hinge structure  120  and the linkage structure  140  in the foregoing embodiment, and is not iterated here. 
       FIG. 18  is a perspective view of part of an electronic device according to another embodiment of the disclosure.  FIG. 19  illustrates the operation of the linkage structure of  FIG. 18 . The main difference between the embodiment shown in  FIG. 18  and  FIG. 19  and the foregoing embodiment is that a linkage assembly  246  of  FIG. 18  and  FIG. 19  does not include a structure (e.g., the third frame  146   e  of the foregoing embodiment and the corresponding assemblies) to drive the functional assemblies to move up and down. The rest of the configuration and the operation mode of the linkage structure  240  shown in  FIG. 18  and  FIG. 19  are similar to the configuration and the operation mode of the linkage structure  140 B of the foregoing embodiment, which is illustrated in detail below. 
     Referring to  FIG. 18  and  FIG. 19 , the linkage structure  240  in the embodiment includes a first pivot assembly  242 , two first shafts  244 , and the two linkage assemblies  246 . The two first shafts  244  are pivotally connected to the first pivot assembly  242  and are respectively connected to two bodies  210   a  and  210   b  and two functional assemblies (not shown but same as the functional assemblies  130   a  and  130   b  in the foregoing embodiment) through the two linkage assemblies  246 . Specifically, each of the linkage assemblies  246  includes a first frame  246   a  and a second frame  246   b . The first frame  246   a  is fixed on the corresponding bodies  210   a  and  210   b  and connected to the corresponding first shaft  244 . The second frame  246   b  is slidably disposed in a sliding groove  246   a   1  of the first frame  246   a  along a first direction D 1  perpendicular to the axial direction of the corresponding first shaft  244  and parallel to the display surface of the corresponding functional assembly and connected to the corresponding functional assemblies. The first pivot assembly  242  is adapted to drive the corresponding second frame  246   b  to slide relative to the corresponding first frame  246   a  along the first direction D 1  between the position shown in  FIG. 18  and the position shown in  19  as the two bodies  210   a  and  210   b  are rotated relative to each other, so that each of the second frames  246   b  drives the corresponding functional assembly to translate along the first direction D 1  relative to the corresponding bodies  210   a  and  210   b.    
     More specifically, each of the linkage assemblies  246  in the embodiment further includes a sliding element  246   c  and a connecting rod  246   d . The sliding element  246   c  is slidably disposed on the first frame  246   a  along a second direction D 2  perpendicular to the first direction D 1  and parallel to the display surface of the corresponding functional assembly. The connecting rod  246   d  is connected between the sliding element  246   c  and the second frame  246   b . The first pivot assembly  242  is adapted to drive the sliding element  246   c  to slide along the second direction D 2  relative to the first frame  246   a  between the position shown in  FIG. 18  and the position shown in  FIG. 19 , so that the sliding element  246   c  drives the second frame  246   b  to slide along the first direction D 1  relative to the first frame  246   a  between the position shown in  FIG. 18  and the position shown in  FIG. 19  through the connecting rod  246   d . In the embodiment, one end of the connecting rod  246   d  is pivotally connected to the sliding element  246   c , and another end of the connecting rod  246   d  is slidably disposed in an arc-shaped groove  246   a   2  of the first frame  246   a  and is connected to the second frame  246   b  in a rotatable and movable manner, so that the sliding element  246   c  sliding along the second direction D 2  is capable of driving the second frame  246   b  to slide along the first direction D 1  through the connecting rod  246   d . In other embodiments, the second frame  246   b  may be driven by other appropriate linkage assemblies, and the disclosure is not limited thereto. 
     Furthermore, the first pivot assembly  242  in the embodiment has two guiding parts  242   a . The two guiding parts  242   a  respectively correspond to the two sliding elements  246   c . As each of the linkage assemblies  246  is rotated relative to the first pivot assembly  242 , the corresponding sliding element  246   c  is guided by the corresponding guiding part  242   a  to slide along the second direction D 2  relative to the first frame  246   a . In the embodiment, the guiding part  242   a  is, for example, a cam, driving the sliding element  246   c  to move along the second direction D 2  as the sliding element  246   c  is rotated relative to the guiding part  242   a . In addition, the first shaft  244  may also have a guiding part  244   a . The guiding part  244   a  is, for example, a cam, driving the sliding element  246   c  to move along the second direction D 2  as the sliding element  246   c  is rotated relative to the guiding part  244   a.    
     Based on the above, in the electronic device of the disclosure, the linkage structure is not a structure included in the hinge structure, so the linkage structure can be independently disposed and apart from the hinge structure instead of being integrated into the hinge structure. Accordingly, when in operation, the hinge structure is not subjected to additional force caused by the configuration of the linkage structure, and the linkage structure disposed independently does not interfere with the structure and the operation of the hinge structure.
