Therefore, when a user manipulates the flexible electronic device from the flattened state as shown in FIG. 1 to the folded state as shown in FIG. 2, for example, by manipulating the first substrate unit 12 as shown in FIG. 1 , When the first substrate unit 12 and the second substrate unit 13 are flat and adjacent to each other, when the first substrate unit 12 is forced toward the height direction D2, the first substrate unit 12 will drive The first bracket unit 5 pivots the first bracket unit 5 toward the second bracket unit 6, and during the pivoting process, as shown in FIGS. 15 to 20, the The first outer connecting section 5115 will drive the first connecting member 53 to move upward, and then link the first inner connecting section 5223, so that the first inner bracket 52 and the first outer bracket 51 rotate synchronously. In this case, because The first straight line L1 passing through the first outer pivoting section 5114 and the first outer connecting section 5115 and the second straight line L2 passing through the first inner pivoting section 5222 and the first inner connecting section 5223 must be kept in one The first parallel state, so that while the first inner bracket 52 and the first outer bracket 51 rotate synchronously counterclockwise, one end of the first connecting member 53 connected to the first inner connecting section 5223 is connected by the first outer The segment 5115 is that the axis is deflected in a clockwise direction relative to the first outer bracket 51, so that the first inner bracket 52 passes from a first top side of the first receiving hole 5117 (that is, close to the first top wall 5111 Sliding) to a first bottom side (ie close to the first bottom wall 5112) of the first accommodating hole 5117 opposite to the first top side.

As shown in FIGS. 15 to 20, during the pivoting of the first bracket unit 5 toward the second bracket unit 6, the end of the first torsion piece 55 connected to the third inner connecting section 5232 is affected by the first Driven by an inner bracket 52, the third outer connecting section 5116 is used as the axis to rotate clockwise relative to the first outer bracket 51, and gradually formed from a vertical state as shown in FIG. 15 as shown in FIG. 19 and The first inner bracket 52 is in a parallel state, so that when the friction force between the first inner bracket 52 and the first outer bracket 51 is provided, the movement of the first inner bracket 52 relative to the first outer bracket 51 can be avoided . In addition, referring to FIG. 21 to FIG. 23, the first inner bracket 52 also drives the first support 541 to rotate synchronously in a counterclockwise direction. More specifically, the first support 541 is around the first fixing section 543 Rotation, while sliding outward relative to the first fixing section 543, because the grooves 5411 of the first supporting body 541 located on the upper and lower sides of the groove wall abut against the two opposite ends of the first fixing section 543 The first supporting body 541 is positioned to rotate in the fixed length direction D1, and the first clamping block 542 is moved from the end of the first clamping groove 5213 adjacent to the top surface of the first inner bracket 52 to the first A clamping slot 5213 is adjacent to one end of the bottom surface of the first inner bracket 52, and referring to FIGS. 24 to 26, the first support plate 121 is also moved relative to the first inner bracket 52, and the first clamping block The distance 542 moves in the first clamping groove 5213 is equal to the distance between the fixing hole 40 and the second pivot hole 48 on the same side.

Similarly, as shown in FIG. 1, when the second substrate unit 13 rotates in the height direction D2, the second substrate unit 13 will drive the second bracket unit 6 so that the second bracket unit 6 faces the first A bracket unit 5 pivots in the direction, that is, as shown in FIGS. 15 to 20, the action of the second bracket unit 6 is the same as the action of the first bracket unit 5, only in the opposite direction, therefore, as the second inner bracket 62 slides from a second top side of the second accommodating hole 6117 (that is, near the second top wall 6111) to a second bottom side of the second accommodating hole 6117 opposite to the second top side ( (I.e. close to the second bottom wall 6112), so that a gap d is formed between the first inner bracket 52 and the second inner bracket 62, and as shown in FIGS. 24 to 26, the second support bracket 64 linked to the second support plate 131, so that the second support plate 131 also moves relative to the second inner bracket 62, so that the first support plate 121 and the second support plate 131 form a shelter space 7, so that the The bending position of the flexible screen 2 can be bent in the avoidance space 7, whereby the avoidance space 7 can avoid the problem of deformation of the flexible screen 2 due to excessive bending. Wherein, the avoidance distance d can be adjusted according to the size of the flexible screen 2 and is not limited to this embodiment.

In the state where the avoidance distance d is formed between the first inner bracket 52 and the second inner bracket 62, as shown in FIG. 1, when the first substrate unit 12 is rotated in the longitudinal direction D1, the first A substrate unit 12 will drive the first bracket unit 5 to pivot the first bracket unit 5 away from the second bracket unit 6, and during the pivoting process, as shown in FIGS. 15 to 20, the The first outer connecting section 5115 of the first outer bracket 51 will drive the first connecting member 53 to move downwards, and then link the first inner connecting section 5223 to synchronize the first inner bracket 52 with the first outer bracket 51 Rotate in a clockwise direction, in this case, since the first straight line L1 passing through the first outer pivoting section 5114 and the first outer connecting section 5115 is connected to the first inner connecting through the first inner pivoting section 5222 The second straight line L2 of the segment 5223 must be maintained in the first parallel state, so the first inner bracket 52 and the first outer bracket 51 rotate clockwise while being connected to one end of the first inner connecting segment 5223 Then, the first outer connecting section 5115 is used as an axis to deflect in a counterclockwise direction relative to the first outer bracket 51, so that the first inner bracket 52 passes from the first bottom side of the first receiving hole 5117 (i.e. (Near the first bottom wall 5112) slides to the first top side of the first accommodating hole 5117 (that is, near the first top wall 5111).

As shown in FIGS. 15 to 20, during the pivoting of the first bracket unit 5 away from the second bracket unit 6, the end of the first torsion member 55 connected to the third inner connecting section 5232 is affected by the Driven by the first inner bracket 52, the third outer connecting section 5116 is used as an axis to rotate in a counterclockwise direction relative to the first outer bracket 51 to return to the vertical state with the first inner bracket 52. In addition, referring to FIGS. 21 to 23, the first inner bracket 52 also drives the first support body 541 to rotate in a clockwise direction, so that the first clamping block 542 is adjacent to the first clamping slot 5213 from the first clamping slot 5213 An end of the bottom surface of an inner bracket 52 moves to an end of the first clamping groove 5213 adjacent to the top surface of the first inner bracket 52, referring to FIGS. 24 to 26, and then the first support plate 121 is also moved relative to the The first inner bracket 52 moves and returns to the flat state.

Similarly, as shown in FIG. 1, when the second substrate unit 13 rotates in the longitudinal direction D1, the second substrate unit 13 will drive the second bracket unit 6 so that the second bracket unit 6 moves away from the The first bracket unit 5 pivots in the direction, and then, as shown in FIGS. 15 to 20, the action of the second bracket unit 6 is the same as the action of the first bracket unit 5, only in the opposite direction. Therefore, as the second The inner bracket 62 slides from the second bottom side of the second receiving hole 6117 to the second top side of the second receiving hole 6117, which will cause the first inner bracket 52 and the second inner bracket 62 to each other Parallel, and as shown in FIGS. 24 to 26, the second support frame 64 links the second support plate 131, so that the second support plate 131 also moves relative to the second inner bracket 62, so that the first support plate 121 is adjacent to the second support plate 131 and is coplanar, so that the bend of the flexible screen 2 can be returned to a flat state and supported by the first support plate 121 and the second support plate 131, thereby enabling The flexible screen 3 is in a flat state for users to use.

In addition, in this embodiment, the first bracket unit 5 and the second bracket unit 6 can also be synchronized by a linkage mechanism. That is, referring to FIG. 6, the pivot mechanism 3 may further include a linking member 8, and the first end 511 of the first outer bracket 51 further includes a first outer sliding section 5118 and the second outer bracket The second end 611 of 61 further includes a second outer sliding section 6118.
