The rotating member 142a is disposed on the arm 130 and is rotatable relative to the arm 130. The moving member 142b is disposed on the arm 130 and coupled to the rotating member 142a to be movable relative to the arm 130, and the first connecting member 144 is fixed to the moving member 142b. Therefore, when the second body 120 is rotated by the temporary connection from the closed position P1 along the first axis A1 to the disengagement position P2 via the temporary connection, the cam rotating shaft 148 pushes the rotating member 142a to rotate relative to the arm 130, and the rotating member The 142a drives the moving member 142b to move relative to the arm 130 to move the first connecting member 144 relative to the second connecting member 146 to release the temporary connection.

In addition, in the embodiment, the link set 142 further includes a first reset member 142c and a second reset member 142d. The first returning member 142c is, for example, a torsion spring disposed between the rotating member 142a and the arm 130. When the second body 120 is rotated relative to the first body 110 along the first axis A1, the rotating member 142a is urged by the cam shaft 148 to rotate relative to the arm 130 and compress the first return member 142c. Therefore, after the second body 120 is rotated to the disengagement position P2 along the first axis A1, the first returning member 142c resets the rotating member 142a that is pushed by the cam rotating shaft 148 to rotate relative to the arm 130.

In addition, the second returning member 142d is, for example, a tension spring, and is disposed between the moving member 142b and the arm 130. When the second body 120 is rotated relative to the first body 110 along the first axis A1, the moving member 142b is moved by the rotating member 142a to move relative to the arm 130 and stretch the second reset member 142d. Therefore, the second body 120 is rotated to and disengaged along the first axis A1. After the position P2, the second returning member 142d resets the moving member 142b that is moved by the rotating member 142a with respect to the arm 130. However, the present invention does not limit the types of the first reset member and the second reset member.

It can be seen that after the second body 120 is rotated to the disengagement position P2 along the first axis A1, the positions of the rotating member 142a, the moving member 142b, the first returning member 142c and the second resetting member 142d of the link group 142 are restored to When the second body 120 is in the position at the closed position P1. Therefore, when the second body 120 is rotated relative to the first body 110 to the closed position P1 along the first axis A1 via the arm 130 from the disengagement position P2, the cam shaft 148 urges the resetted rotating member 142a to rotate relative to the arm 130. The rotating member 142a drives the reset moving member 142b to move relative to the arm 130 to move the first connecting member 144 relative to the second connecting member 146 to resume the temporary connection.

During this process, the rotating member 142a is pushed by the cam rotating shaft 148 to rotate relative to the arm 130 and compresses the first returning member 142c. The moving member 142b is driven by the rotating member 142a to move relative to the arm 130 and stretch the second. Reset member 142d. Therefore, after the second body 120 is rotated to the closed position P1, the first returning member 142c resets the rotating member 142a that is pushed by the cam rotating shaft 148 to rotate relative to the arm 130, and the second resetting member 142d is reset by the rotating member 142a. The moving member 142b is moved relative to the arm 130. Accordingly, the electronic device 100 can repeatedly perform the above operations.

Referring to FIG. 1 and FIG. 5A , in the embodiment, when the second body 120 is in the closed position P1 , the second body 120 is overlapped with the first body 110 , and the display surface 122 faces the keyboard 112 . The second body 120 can be rotated to the disengaged position along the first axis A1 from the closed position P1 via the temporary connection via the arm 130 P2 is set, and the process is as shown in FIGS. 1 to 2 and as shown in FIGS. 5A to 5B.

On the other hand, referring to FIG. 5B, in the embodiment, the arm 130 can rotate relative to the first body 110 along the first axis A1 to have a first torque T1, and the second body 120 can be along the second axis A2. The arm 130 rotates to have a second torque T2, and the temporary connection has a torque M with respect to the second axis A2. When the second body 120 is rotated relative to the first body 110 to the disengagement position P2 from the closed position P1 via the arm 130, the sum of the second torque T2 and the torque M is greater than the first torque T1 to maintain the second body 120 and Synchronous movement of the arms 130. At this time, the electronic device 100 can function as a notebook computer, and the user can operate the keyboard 112 while viewing the display surface 122.

When the second body 120 is located at the disengagement position P2, the first body 110 and the second body 120 have a predetermined angle θ. At this time, the link group 142 releases the temporary connection between the first link 144 and the second link 146 in the aforementioned manner. Therefore, after the second body 120 is rotated to the disengagement position P2 to release the temporary connection of the second body 120, the second body 120 can be rotated relative to the arm 130 along the second axis A2 via the second torque T2 being less than the first torque T1. The display surface 122 faces away from the keyboard 112, and the process thereof is as shown in FIGS. 5B to 5C. At this time, the user can operate the keyboard 112 and cause another user to view the display surface 122 in the other direction.

After the second body 120 rotates relative to the arm 130 along the second axis A2 to change the direction of the display surface 122, the second body 120 can rotate relative to the first body 110 along the first axis A1 from the disengagement position P2 via the arm 130. To the closed position P1. At this time, the second body 120 is overlapped with the first body 110, and the display surface 122 faces away from the keyboard 112. Therefore, the electronic device 100 originally used as a notebook computer can be used as a tablet PC. The user can operate the electronic device 100 by touching the display surface 122 having the touch function.

FIG. 6 is a schematic diagram of the operation of the electronic device of FIG. 1. FIG. Referring to FIG. 5A, FIG. 5B and FIG. 6, after the second body 120 is rotated to the disengagement position P2 to release the temporary connection of the second body 120 (the process is as shown in FIG. 5A to FIG. 5B), the second body 120 can be along The second axis A2 rotates relative to the arm 130 while the arm 130 rotates relative to the first body 110 along the first axis A1 such that the second body 120 stands on the first body 110 via the support of the arm 130, The process is shown in Figure 5B and Figure 6. Accordingly, the electronic device 100 can change its operation mode by adjusting the second body 120.

Therefore, in the process of the second body 120 rotating with the arm 130 relative to the first body 110, the second body 120 can move synchronously with the arm 130 by the temporary connection provided by the disengagement mechanism 140. The second body 120 is prevented from rotating against the arm 110 during the rotation of the arm 130 relative to the first body 110 to strike the first body 110.

Further, when the second body 120 is rotated to the disengagement position P2, the disengagement mechanism 140 can automatically release the temporary connection, and the second body 120 can be rotated relative to the arm 130 to change the direction of the display surface 122. Therefore, the electronic device 100 can adjust the timing at which the disengagement mechanism 140 releases the temporary connection by changing the angle of the predetermined angle θ. Accordingly, the electronic device 100 has a relatively simple operation mode and can reduce the probability of damage.
