Please refer to FIG2 , FIG3 , FIG6 and FIG7 , the supporting mechanism 100 further includes a first stopper 160 and a second stopper 170 .

具體而言，第一限位件160具有一第一樞接端161及一第一活動端162，且第一樞接端161樞接於基座110。第二限位件170具有一第二樞接端171及一第二活動端172，且第二樞接端171樞接於基座110。Specifically, the first position-limiting member 160 has a first pivoting end 161 and a first movable end 162 , and the first pivoting end 161 is pivoted to the base 110 . The second position-limiting member 170 has a second pivoting end 171 and a second movable end 172 , and the second pivoting end 171 is pivoted to the base 110 .

When the support member 150 moves relatively away from the base 110, the first surface 124 is parallel to the third surface 163, and the second surface 134 is parallel to the fourth surface 173.

當支撐件150相對移動靠近於基座110時，第一活動端162及第二活動端172相對移動靠近彼此，第三表面163相對於第一表面124展開一夾角θ，且第四表面173相對於第二表面134展開夾角θ，且第一活動端162及第二活動端172適於抵接於可撓顯示螢幕230。此時，第一活動端162及第二活動端172之間的一第一距離D1小於第一樞接端161及第二樞接端171之間的一第二距離D2。據此，在閉合狀態下，第一活動端162及第二活動端172能對可撓顯示螢幕230提供額外的支撐力。When the supporting member 150 moves relatively close to the base 110, the first movable end 162 and the second movable end 172 move relatively close to each other, the third surface 163 opens an angle θ relative to the first surface 124, and the fourth surface 173 opens an angle θ relative to the second surface 134, and the first movable end 162 and the second movable end 172 are suitable for abutting against the flexible display screen 230. At this time, a first distance D1 between the first movable end 162 and the second movable end 172 is smaller than a second distance D2 between the first pivot end 161 and the second pivot end 171. Accordingly, in the closed state, the first movable end 162 and the second movable end 172 can provide additional support to the flexible display screen 230.

在其它實施例中，折疊式電子裝置亦可不設置第一限位件及第二限位件，而於閉合狀態下，僅以第一支架的第一表面及第二支架的第二表面對可撓顯示螢幕提供支撐，本發明並無限制可撓顯示螢幕的支撐方式。In other embodiments, the foldable electronic device may not be provided with the first limiting member and the second limiting member. In the closed state, only the first surface of the first bracket and the second surface of the second bracket provide support for the flexible display screen. The present invention does not limit the supporting method of the flexible display screen.
