The sensing element 160 is, for example, a pressure sensing element and is disposed in the hub 116 between the bracket B1 and the elastic piece W. The control unit 150 is disposed on the body 112 and is coupled to the sensing element 160 and the electromagnet 140.

當兩機體112、114從圖1所示的展開狀態逐漸閉合至圖2所示的閉合狀態時，兩機體112、114的展開角度逐漸減少。反之，當兩機體112、114從圖2所示的閉合狀態逐漸展開至圖1所示的展開狀態，兩機體112、114的展開角度逐漸增加。在所述展開及閉合過程中，托架B2的末端E沿著轉軸S的螺紋轉動而改變其往托架B2對彈片W施加的壓迫力，使樞紐116的扭力值產生變化。亦即，樞紐116的扭力值相關於兩機體112、114的展開角度。被彈片W壓迫的感測元件160適於感測所述扭力值的變化而可推知兩機體112、114當下的展開角度，並將對應的感測訊號傳遞至控制單元150，使控制單元150能夠據以控制電磁鐵140的磁極性改變。在其他實施例中，可藉由其他種類的感測元件來感測兩機體112、114的展開角度，本發明不對此加以限制。When the two bodies 112 and 114 are gradually closed from the expanded state shown in FIG. 1 to the closed state shown in FIG. 2, the expansion angles of the two bodies 112 and 114 gradually decrease. Conversely, when the two bodies 112 and 114 are gradually expanded from the closed state shown in FIG. 2 to the expanded state shown in FIG. 1, the expansion angles of the two bodies 112 and 114 gradually increase. During the expansion and closing process, the end E of the bracket B2 rotates along the thread of the shaft S to change the pressing force applied to the bracket B2 on the elastic piece W, so that the torque value of the hinge 116 changes. That is, the torque value of the hinge 116 is related to the deployment angle of the two bodies 112 and 114. The sensing element 160 compressed by the shrapnel W is adapted to sense the change in the torque value to infer the current deployment angles of the two bodies 112 and 114, and transmit the corresponding sensing signals to the control unit 150 so that the control unit 150 can Accordingly, the magnetic polarity of the electromagnet 140 is controlled to change. In other embodiments, other types of sensing elements can be used to sense the unfolding angles of the two bodies 112 and 114, which is not limited in the present invention.

Specifically, when the expansion angles of the two bodies 112 and 114 gradually decrease, the control unit 150 sequentially controls the magnetic polarity of the partial electromagnets 140 to change along the direction D1 as shown in FIGS. 8A to 8C, so that the partial electromagnets 140 The magnetic repulsion between the magnet 130 and the other part of the electromagnet 140 and the magnetic attraction between the magnet 130 drive the magnet 130 and the flexible display panel 120 to move in the direction D1, so that the two bodies 112, 114 and the flexible display panel 120 Can be closed smoothly. Conversely, when the expansion angles of the two bodies 112 and 114 gradually increase, the control unit 150 sequentially controls the magnetic polarity of the partial electromagnet 140 to change in the reverse direction of the direction D1 as shown in FIG. 8C to FIG.
