Accordingly, when the second body 120 is unfolded relative to the first body 110, the connection point PA moves downward by a displacement amount α1, the connection point PB generates a displacement amount α2 with the same distance and opposite direction as the displacement amount α1, and the connection point PC generates a displacement amount α2 with the same distance and opposite direction as the displacement amount α1. The displacement amount α2 is the same distance from the displacement amount α3 in opposite directions, so the first rope body 134 and the second rope body 135 can respectively perform a push and a pull force to drive the pivot member 142 to rotate.

For example, if the radius r of the pivoting member 142 is 1.5 mm, the maximum rotation angle θ2 of the second body 120 is 180 degrees, which is converted into a diameter of 180×π/180=3.14 (wherein π is calculated as 3.14), Then the maximum displacement α _max required by the displacement α2 and the displacement α3 is the arc length S, and S=1.5mmx(180xπ/180)=4.71mm can be obtained through the formula S=rxθ1. This value can still be calculated according to the manufacturing requirements. tolerance.

For example, when the electronic device 100 transitions from the state shown in FIGS. 1 and 2 to the state shown in FIGS. 5 and 6 , the hinge structure 150 is rotated to drive the sliding member 131 to slide toward the direction of the hinge structure 150 . The first link 132 and the second link 133 are sequentially driven to rotate by the sliding member 131 . Next, the second link 133 pulls the second rope body 135 to make the pivot member 142 rotate counterclockwise. As the pivot member 142 rotates counterclockwise, the pivot member 142 can be retracted by the second link 133 at the same time. The first rope body 134 is released.

On the contrary, when the electronic device 100 transitions from the state shown in FIG. 5 to the state shown in FIG. 1 , the hinge structure 150 rotates to drive the sliding member 131 to slide in a direction away from the hinge structure 150 , and the sliding member 131 drives the sliding member 131 in sequence. The first link 132 and the second link 133 rotate in opposite directions. Next, the second link 133 pulls the first rope body 134 to make the pivot member 142 rotate clockwise. As the pivot member 142 rotates clockwise, the pivot member 142 can be retracted by the second link 133 at the same time. The second rope body 135 is released.

Body 220. Therefore, the first pivot portion 222 serves as a fulcrum for the rotation of the first link 132 , and the second pivot portion 223 serves as a fulcrum for the rotation of the second link 133 . In particular, the first link and the second link of the embodiment shown in FIG. 2 to FIG. 8 are pivotally connected to the second body in the same manner as this embodiment, and the fixing frame 121 can also be used for pivot connection in this embodiment. The first link 132 and the second link 133 .

Referring to FIG. 10 , the guide member 237 is coupled to the pivot member 242 and is slidably disposed on the second body 220 . The other end of the first rope body 134 and the other end of the second rope body 135 are respectively connected to opposite sides of the guide member 237 . The first rope body 134 and the second rope body 135 contact the cylinder 224 , and the cylinder 224 is used to limit the positions of the first rope body 134 and the second rope body 135 and ensure the movement of the first rope body 134 and the second rope body 135 . Herein, the cylinder 224 can be replaced with the wheel body of the embodiment shown in FIG. 2 , which can further reduce the frictional force when the rope body is actuated, and assist the rope body to act more smoothly and smoothly.

The pivot member 242 has a guide groove 242a. The guide member 237 has a guide post 237a. The guide post 237a is inserted into the guide groove 242a.

The connection point PA can generate a displacement amount β1. The relationship between the lead L of the thread of the pivot member 242 and the maximum displacement β _max required by the connection point PB and the connection point PC is β _max =Lx(θ2/360). For example, if the lead L is 10mm, and the maximum rotation angle θ2 of the second machine 220 is 360 degrees, the maximum displacement βmax required by the connection point PB and the connection point PC is 10mmx( _360/360 ), namely Equal to 10mm, ie β _max =10mm. In addition, if the lead L is also 10 mm, but the maximum value of the rotation angle θ2 of the second body 220 is changed to 180 degrees, the maximum displacement β _max required for the connection point PB and the connection point PC is 5mm×(360/360), that is Equal to 5mm, ie β _max =5mm.
