Reference location.

Referring to FIG. 14, in addition, before the operation of this embodiment is described in detail, in this embodiment, the pivoting mechanism 3 is a parallel hyperbolic rod mechanism. Taking the first bracket unit 5 as an example, a first bracket unit 5 can be defined. A straight line L1 and a second straight line L2. The first straight line L1 passes through the first outer pivoting section 5114 and the first outer connecting section 5115, the second straight line L2 passes through the first inner pivoting section 5222 and the first inner connecting section 5223, and the first straight line L1 It remains parallel to the second straight line L2 in any state.

The third straight line L3 passes through the second outer pivotal section 6114 and the second outer connecting section 6115, The fourth straight line L4 passes through the second inner pivoting section 6222 and the second inner connecting section 6223, and the third straight line L3 and the fourth straight line L4 remain parallel in any state.

Therefore, when a user manipulates the flexible electronic device from the flat state shown in FIG. 1 to the folded state shown in FIG. 2, for example, manipulation of the first substrate unit 12 shown in FIG. , The first substrate unit 12 and the second substrate unit 13 are in a flat and adjacently arranged state, when the first substrate unit 12 is forced in the height direction D2, the first substrate unit 12 will drive The first bracket unit 5 causes the first bracket unit 5 to pivot toward the second bracket unit 6, and during the pivoting process, as shown in FIGS. 15 to 20, the first outer bracket 51 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 to make 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 In the first parallel state, the first inner bracket 52 and the first outer bracket 51 rotate counterclockwise synchronously, and at the same time, the 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 the axis deflection in the clockwise direction relative to the first outer bracket 51, so that the first inner bracket 52 is moved from a first top side of the first accommodating hole 5117 (that is, close to the first top wall 5111). ) Slide to a first bottom side of the first accommodating hole 5117 opposite to the first top side (ie, close to the first bottom wall 5112).

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 member 55 connected to the third inner connecting section 5232 is affected by the first An inner bracket 52 is driven by the third outer connecting section 5116 as the axis to rotate in a clockwise direction relative to the first outer bracket 51 to gradually form a vertical state as shown in FIG. 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, it can avoid restricting the movement of the first inner bracket 52 relative to the first outer bracket 51 . In addition, referring to FIGS. 21 to 23, the first inner bracket 52 also drives the first support body 541 to rotate in a counterclockwise direction synchronously. More specifically, the first support body 541 is around the first fixing section 543. While rotating, it also slides outward relative to the first fixing section 543. Because the sliding groove 5411 of the first support body 541 is located on the upper and lower sides of the groove walls abut against the two opposite ends of the first fixing section 543. The first supporting body 541 is positioned to rotate in the fixed longitudinal direction D1, and the first locking block 542 is moved from the end of the first locking groove 5213 adjacent to the top surface of the first inner bracket 52 to the first A locking slot 5213 is adjacent to one end of the bottom surface of the first inner bracket 52. Refer to FIGS. 24 to 26 in conjunction with the first supporting plate 121 to move relative to the first inner bracket 52. The first locking block The distance that the 542 moves in the first locking 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 is rotated in the height direction D2, the second substrate unit 13 will drive the second support unit 6 so that the second support 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 that of the first bracket unit 5, but the direction is opposite. Therefore, as the second inner bracket 62 slides from a second top side of the second accommodating hole 6117 (that is, close to the second top wall 6111) to a second bottom side of the second accommodating hole 6117 opposite to the second top side ( That is, close to the second bottom wall 6112), a clearance distance d is formed between the first inner bracket 52 and the second inner bracket 62. At the same time, as shown in FIGS. 24 to 26, the second support frame 64 is 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 retreat space 7 so that the The bending part of the flexible screen 2 can be bent in the avoiding space 7 so that the avoiding 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 correspondingly 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 second A base plate unit 12 will drive the first support unit 5 to pivot the first support unit 5 away from the second support 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 downward, thereby linking 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 section 5222 through the first inner pivoting section 5222 The second straight line L2 of the section 5223 must be maintained in the first parallel state, so the first inner bracket 52 and the first outer bracket 51 rotate clockwise synchronously, and are connected to one end of the first inner connecting section 5223. The first outer connecting section 5115 is taken as the axis to deflect in a counterclockwise direction relative to the first outer bracket 51, so that the first inner bracket 52 is moved from the first bottom side of the first receiving hole 5117 (ie (Close to the first bottom wall 5112) to the first top side of the first accommodating hole 5117 (that is, close to the first top wall 5111).

As shown in FIGS. 15 to 20, during the pivoting of the first bracket unit 5 in a direction away from the second bracket unit 6, the end of the first torsion member 55 connected to the third inner connecting section 5232 is subjected to the The first inner bracket 52 is driven by the third outer connecting section 5116 as the axis to rotate counterclockwise relative to the first outer bracket 51 to return to the vertical state with the first inner bracket 52. In addition, referring to Figures 21 to 23, the first inner bracket 52 also drives the first support body 541 to rotate in a clockwise direction synchronously, so that the first locking block 542 is adjacent to the first locking slot 5213 from the first locking slot 5213 One end of the bottom surface of an inner bracket 52 moves to an end of the first locking groove 5213 adjacent to the top surface of the first inner bracket 52. Refer to FIGS. 24 to 26 in conjunction with the first supporting plate 121 to move 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 is rotated in the longitudinal direction D1, the second substrate unit 13 will drive the second support unit 6 to move the second support unit 6 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 that of the first bracket unit 5, except that the direction is opposite. Therefore, as the second bracket unit 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, so that the first inner bracket 52 and the second inner bracket 62 are mutually 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 and coplanar with the second support plate 131, so that the bend of the flexible screen 2 can be restored to a flat state and supported by the first support plate 121 and the second support plate 131, thereby making The flexible screen 3 is in a flat state for users to use.

In addition, in this embodiment, the first support unit 5 and the second support unit 6 can also be synchronized by a linkage mechanism. That is, referring to FIG. 6, the pivoting mechanism 3 may further include a link 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 also includes a second outer sliding section 6118. Specifically, the linkage member 8 is located in the through hole 1131 of the second extension wall 113 and is adjacent to the inner surface 41 of the cam 4. The linkage member 8 is generally rectangular, and there are two The perforations 81 of the arc-shaped sliding holes 49 of the cam 4 are spaced apart in the direction D1 and respectively communicate with each other. The first outer sliding section 5118 extends in the width direction D3 in which the first outer pivoting section 5114 extends, and extends through the arc-shaped sliding hole 49 and the corresponding through hole 81 near the first arc surface 43 , And one end of which penetrates the first side wall 5113 and the other end abuts against the side of the linkage 8 that faces away from the cam 4, and the first outer sliding section 5118 takes the first outer pivoting section 5114 as The shaft center slides along the path of the arc-shaped sliding hole 49. In addition, the second outer sliding section 6118 extends in the width direction D3 in which the second outer pivoting section 6114 extends, and extends through the arc-shaped sliding hole 49 near the second arc surface 44 and the corresponding A through hole 81, one end of which penetrates the second side wall 6113 and the other end abuts against the side of the linkage 8 facing away from the cam 4, and the second outer sliding section 6118 is connected to the second outer pivot section 6114 is the axis sliding along the path of the arc-shaped sliding hole 49.

Therefore, referring to Figures 27 to 29, the first outer sliding section 5118 slides from the upper end to the lower end of the arc-shaped sliding hole 49 during the pivoting of the first support unit 5 toward the second support unit 6. Move and press against the linking member 8, so that the linking member 8 moves to the lower side of the penetrating hole 1131 of the second extension wall 113, the linking member 8 is pressed against the second outer sliding section 6118, thereby causing The second outer sliding section 6118 slides from the upper end to the lower end of the arc-shaped sliding hole 49, thereby enabling the second support unit 6 to pivot in the direction of the first support unit 5 synchronously.

In summary, the flexible electronic device of the present invention simultaneously pivots relative to the cam 4 through the first inner bracket 52 and the second inner bracket 62 of the two pivoting mechanisms 3, so that the first support plate 121 and the second The two supporting plates 131 slide in the opposite direction, and together provide a relief space 7 for the flexible screen 2 to bend and protrude, so as to solve the problem of the difference between the inner and outer circumferences caused by the bending of the flexible screen 2. This reduces the volume of the flexible electronic device to improve portability. In addition, since the pivoting mechanisms 3 are not directly arranged on the flexible screen 2, the design or manufacturing personnel of the pivoting mechanism 3 are not required It takes time to design the bending details of the pivoting mechanism 3, so that the flexibility of use of the pivoting mechanism 3 can be improved and the manufacturing cost thereof can be reduced.
