Please refer to Figure 5. Assuming that the torque generated by the rotation of the rotating wheel 333 is 3 (Kg-cm), the angle θ is 69.32 degrees, the distance L is 0.18 (cm), the initial torque in the 1 direction of the first body is 7.2 (Kg-cm), the initial moment of the second body in the 2-direction is 5.4 (Kg-cm) for example.

The upward thrust F1 is equal to 3 (Kg-cm) divided by 0.18 and multiplied by Cosθ, which is approximately equal to 5.88 (Kg). Furthermore, the force arm D1 is equal to 1.34 (cm), and the resistance arm D2 is equal to 0.69 (cm). Therefore, the downward push force F2 is equal to 5.88 times 1.34 (cm) divided by 0.69 (cm), which is approximately equal to 11.43 ( kg).

The additional moment generated by the pivot structure 3 in the direction of the second body 2 is the upward thrust F1 (5.88Kg) multiplied by a torque arm D3 (1.04cm) between the center of the rotating shaft 31 and the center of the rotating wheel 333. Multiplied by 2, it is approximately equal to 12.24 (Kg-cm); the additional moment generated by the pivot structure 3 in the direction of the first body 1 is the downward thrust F2 (11.43Kg) multiplied by the resistance arm D2 (0.69cm) Multiplied by 2, it is approximately equal to 15.77 (Kg-cm). Therefore, the total moment of the first body in the 1 direction (5.4+15.77=21.17) is greater than the total moment of the second body in the 2 direction (7.2+12.24=19.44), which means that the electronic device of the present invention is at the pivot. With the help of the shaft structure 3, the user can open the second body 2 with one hand without causing the first body 1 to lift.

Based on the above, the electronic device and its pivot structure of the present invention can, under the operation of the linkage component, use the second body to perform a cover opening action relative to the first body, so that the force-applying end of the rod exerts The upward thrust, under the action of the lever balance, causes the corresponding force-bearing end of the rod to generate the downward thrust. In this way, the electronic device and its pivot structure of the present invention can generate additional torque when opening the cover, allowing the user to operate with only one hand, but will not cause the first body to be relatively lifted. It has the effect of improving the operability of electronic devices.
