At the same time, the rotating member 254 and the positioning base 251 rotate with each other through the cooperation of the second arc rail 2516 and the second arc groove 2540, so that the first rotating part 2541 rotates into the corresponding receiving groove 2517, and the positioning base 251 faces two opposite sides. The rotating parts 254 on the side are away from each other, and the driven parts 255 on opposite sides of the positioning base 251 are away from each other, so that the two side supports 233 are smoothly flattened until the front faces of the two side supports 233 are in contact with the front faces of the positioning base 251 Coplanar. At this time, the opposite sides of the side support plate 2331 are respectively supported by the first arc rail 2562 of the connector 256 and the adjustment shaft 2511.

The connecting member 256 slides, causing the rotating member 254 and the driven member 255 to rotate relative to the positioning seat 251 toward the side close to the flexible member 30; at the same time, the connecting member 256 drives the first arc rail 2562 to move on the first arc rail 2562 of the side support member 233. Rotating in an arc groove 2334, the adjusting shaft 2511 on the positioning base 251 slides and rotates in the adjusting groove 2335 of the corresponding adjusting part 2330, causing the rotating mechanisms 250 on both sides of the positioning base 251 to relatively rotate and move closer to each other to drive The two side supports 233 are close to each other until the two side supports 233 and the positioning seat 251 form a drop-shaped cross section; the bendable area 31 of the flexible member 30 is bent with the rotating shaft device 22 until it can be bent. The area 31 is bent into a drop shape, thereby realizing the folding of the electronic device 100 .

During the process of bending the electronic device 100, the bendable area 31 of the flexible member 30 is bent into a drop shape, thereby reducing the duty cycle of the bent area 31, thereby reducing the overall size of the electronic device 100. thickness.

In other bending methods of the electronic device 100, bending force can also be applied to the two frames 21 at the same time.
