The upper end of the left side surface 453 forms the outward-expanding arc surface 4532 which protrudes toward the first bracket unit 41 and is connected with the concave arc surface 4531 and the top side surface 451. In addition, the structure of the right side 454 and the structure of the left side 453 are horizontally mirror images, i.e., the two are symmetrical structures, which are not described in detail herein. The limiting hole 455 extends along the longitudinal direction D2, and a lower end of the limiting hole 455 adjacent to the left side surface 453 further extends toward the left side surface 453 to form a left arc surface 4551 connected to a hole wall of the limiting hole 455, and a lower end of the limiting hole 455 adjacent to the right side surface 454 further extends toward the right side surface 454 to form a right arc surface 4552 connected to the hole wall of the limiting hole 455, so that the left arc surface 4551 and the right arc surface 4552 respectively provide the first locking section 4162 and the second locking section 4362 to abut against each other, so that the first movable bracket 411 and the second movable bracket 431 do not separate from the cam 45 when pivoting relative to the cam 45.

As the first convex segment 4161 passes in the clockwise direction over the flared arc 4532, the first clamping segment 4162 continues to slide downward against the left arc 4551. During the process that the first protruding section 4161 enters the top side surface 451, the first locking section 4162 moves out of the left arc surface 4551 and moves to the bottom end of the limiting hole 455 to form a vertical state as shown in fig. 11.

In a state that the first movable bracket 411 and the second movable bracket 431 are relatively close to each other, as shown in fig. 14, when the first housing 22 is applied with a force in the transverse direction D1, the first housing 22 applies a force to the first support plate 312 and the first base 311, so that the first bracket unit 41 pivots in a direction away from the second bracket unit 43, and in the pivoting process, as shown in fig. 11 to 9, the first protruding section 4161 slides downward from the top side surface 451 along the outward-expanding arc surface 4532 and moves into the inward-concave arc surface 4531, so that the first movable bracket 411 moves in a direction approaching the cam 45, and at the same time, the first base 311 is driven to slide in a direction approaching the first side plate 32 and abut against each other (as shown in fig. 12).

In summary, in the flexible electronic device of the present invention, the first movable bracket 411 and the second movable bracket 431 of the two pivoting mechanisms 4 are pivoted relative to the cam 45 synchronously, so that the first substrate unit 31 and the second substrate unit 33 slide respectively in a direction away from the first side plate 32 and the second side plate 34, and the first side plate 32, the second side plate 34 and the bottom plate 35 sink relatively and together provide a clearance space 5 for the flexible screen 1 to bend and protrude, so as to solve the problem of difference in inner and outer perimeter length caused by bending the flexible screen 1, and thereby reduce the volume of the flexible electronic device to improve the portability, and in addition, since the pivoting mechanism 4 is not directly disposed on the flexible screen 1, the design of the pivoting mechanism 4 or the manufacturer does not need to design the folding details of the pivoting mechanism 4, therefore, the usage flexibility of the pivot mechanism 4 can be improved and the manufacturing cost thereof can be reduced, so as to achieve the purpose of the present invention.
