Abstract: A pivot device with an interlocking lifting mechanism includes a first interlocking member to which first and second shafts and a second interlocking member are pivotably connected. A torque device is mounted around the first and second shafts. A third interlocking member is pivotably connected to the second interlocking member and includes a sliding groove. A fixing seat includes a pivotal member extending through the sliding groove. The second interlocking member is slidably received in a guiding groove of the guiding seat. When the first shaft pivots through a certain angle, the first interlocking member pivots about the second shaft and actuates the second interlocking member. The third interlocking member pivots relative to the fixing seat. The sliding groove slides relative to the pivotal member. The second distal end synchronously slides relative to the first guiding groove to lift an auxiliary screen unit connected to the third proximal end.

Abstract: A pivot device includes first and second shafts. A first torque component unit is coupled to an end of the first shaft. A second torque component unit is coupled to an end of the second shaft. A positioning unit is coupled to another ends of the first and second shafts and includes a first positioning board, a second positioning board, and a positioning block. A first transmission unit is disposed between the first and second positioning boards. A second transmission unit is disposed between the second positioning board and the positioning block. Each of the first and second transmission units includes a wheel mounted on the first shaft, a cam mounted on the second shaft, and a sliding block movable between the wheel and the cam, with each sliding block selectively stopping the wheel or the cam to prevent rotation of the first or second shaft, providing multi-stage switching.
