Please refer to Figures 12 and 13, when the first drive shaft 21 automatically rotates to drive the first front wing rod 321 to pivot relative to the fixed housing 11, thus driving the first panel body 5 to rotate relative to the fixed housing 11. Panel body The rotation of 5 causes the first rear link 332 to rotate with the first connecting axis L1 as the axis, and the first rear wing rod 322 to rotate with the first rotation axis M1 as the axis. In addition, the first front wing rod 321 drives the first front panel body 5 to rotate while also driving the first front link 331 to pivot relative to the first front wing rod 321 in the first arc-shaped groove 53 and pull the first lifting plate 31 The first lifting plate 31 is located between the first filling block 52 and the fixed shell 11, and correspondingly rotates relative to the fixed shell 11 in the first side shell 51 with the first central axis C1 as an axis.

As mentioned above, when the second drive shaft 22 rotates by itself to drive the second front wing rod 421 to pivot relative to the fixed housing 11, thus driving the second panel body 6 to rotate relative to the fixed housing 11, the second panel body 6 rotates The second rear link 432 is rotated with the second connecting axis L2 as the axis, and the second rear wing rod 422 is linked to rotate with the second rotation axis M2 as the axis. In addition, the second front wing rod 421 not only drives the second panel body 6 to rotate, but also drives the second front link 431 to pivot in the second arc-shaped groove 63 relative to the second front wing rod 421 and pull the second lifting plate 41 The second lifting plate 41 is located between the second filling block 62 and the fixed shell 11, and correspondingly rotates relative to the fixed shell 11 in the second side shell 61 with the second central axis C2 as the axis.

Through the above-mentioned operation method, when the first panel body 5 and the second panel body 6 have been rotated to have an angle of 90 degrees between each other (for example, as shown in FIG. 13), at this time, since the flexible screen 7 is disposed on the first panel The main body 5 and the parts on the second panel main body 6 are fixed, so the bendable area 71 will be slightly bent. In order to allow the bendable area 71 to bend smoothly in this process, avoid improper squeezing or even As a result, the bending phenomenon occurs. The first lifting plate 31 and the second lifting plate 41 are both located at a transitional position R2 and are relatively close to the first outer surface 512 and the second outer surface 612, respectively, so that the first lifting plate 31 and the second lifting plate The volume of the relief space S defined by 41 and the fixed shell 11 is increased.

鄰近第一外表平面512，第二心軸線C2與第二連軸線L2的垂直連線

較第二轉軸線M2與第二樞軸線P2的垂直連線

鄰近該第二外表平面612；換言之，第一升降板31及第二升降板41分別位於一沉降位置R3而分別與第一外表平面512及第二外表平面612之間具有一最短垂直距離d2。固定殼11、第一升降板41、及第二升降板51因此共同界定出讓位空間S的容積最大，以供可彎折區71順利地容設。 14-16, when the first drive shaft 21 and the second drive shaft 22 continue to rotate the first front wing rod 321 and the second front wing rod 421 until the first panel body 5 and the second panel body 6 are opposite In the folded state, the bendable area 71 is completely bent (in a drop-shaped cross section), the first lifting surface 311, the first front supporting surface 3211, and the first rear supporting surface 3221 are substantially parallel but not joined, and the second The lifting surface 411, the second front supporting surface 4211, the second rear supporting surface 4221 are substantially parallel but not joined, and the first front supporting surface 3211 and the second front supporting surface 4211 are located between the first lifting surface 311 and the second lifting surface 411 In the same way, the first rear supporting surface 3221 and the second rear supporting surface 4221 are located between the first lifting surface 311 and the second lifting surface 411.

Compared with the vertical line between the first pivot axis M1 and the first pivot axis P1

Adjacent to the first outer surface 512, the vertical line between the second central axis C2 and the second connecting axis L2

The vertical connection between the second pivot axis M2 and the second pivot axis P2

It is adjacent to the second outer surface 612; in other words, the first lifting plate 31 and the second lifting plate 41 are respectively located at a settling position R3 and have a shortest vertical distance d2 from the first outer surface 512 and the second outer surface 612, respectively. The fixed shell 11, the first lifting plate 41, and the second lifting plate 51 therefore jointly define the maximum volume of the relief space S for the bendable area 71 to be accommodated smoothly.

When the sensing unit 82 senses that the first panel body 5 and the second panel body 6 are relatively folded, the control board 83 controls the motor body 23 to stop the first drive shaft 81 and the second drive shaft 22 Operation.

If the operating member 81 is activated again at this time, the first drive shaft 21 and the second drive shaft 22 will re-rotate to cause the first front wing rod 321 and the second front wing rod 421 to drive the first panel body 5 and the first panel body 5 and the second front wing rod. The two-panel body 6 is re-converted back to the unfolded state (transformed from the state of FIG. 16 to the state of FIG. 10), the first lifting plate 31 and the second lifting plate 41 respectively move away from the first outer surface 512 and the second outer surface from the settling position R3 The plane 612 moves in the direction, passes through the transition position R2, and finally returns to the support position R1 respectively, and the space S also gradually changes from the maximum to the minimum. When the sensing unit 82 senses that the first panel body 5 and the second panel body 6 are in a relatively unfolded state, similarly, the control board 83 immediately controls the motor body 23 so that the first drive shaft 21 and the second drive shaft The lever 22 stops operating.

It should be noted that in other embodiments of the present creation, the control module 8, the first auxiliary shaft core 24, and the second auxiliary shaft core 25 can also be omitted, and the first front wing rod 321 and the first rear wing rod 322 are both It is pivotally connected to the first driving shaft 21, the second front wing rod 421 and the second rear wing rod 422 are both pivotally connected to the second driving shaft 22, and the user directly controls the first panel body 5 and the second panel body 6 When an external force is applied, when the first panel body 5 and the second panel body 6 transition from the unfolded state to the collapsed state, the first panel body 5 drives the first front wing rod 321, and the second panel body 6 drives the second front wing rod 421 , So that the first link unit 33 and the second link unit 43 pivots and pulls the first lifting plate 31 and the second lifting plate 41, respectively, so that the first lifting plate 31 and the second lifting plate 41 are rotated relative to the fixed housing 11, and the maximum volume of the space S can be formed. The bending area 71 is accommodated.

In summary, the feature of this creation is that through the combination of two four-bar linkages (the first front linkage 331, the first front wing rod 321, the first lifting plate 31, and the fixed shell 11 are essentially a four-bar linkage Mechanism; the second front link 431, the second front wing rod 421, the second lifting plate 41 and the fixed shell 11 are essentially a four-bar linkage mechanism), consisting of the first lifting plate 31, the second lifting plate 41 and the fixed shell 11 The defined relief space S changes correspondingly with the bending state of the bendable area 71. As shown in Fig. 10, when the first panel body 5 and the second panel body 6 are in a relatively unfolded state, the bendable area 71 is flattened (that is, the degree of bending is the smallest) without too much room for accommodation, giving way to The space S correspondingly defines the minimum volume. As shown in FIG. 16, when the first panel body 5 and the second panel body 6 are in a relatively folded state, the bendable area 71 is bent to the greatest extent and requires the largest accommodating space 12, and the space S correspondingly defines the maximum volume The bendable area 71 is accommodated, and the bendable area 71 can be properly protected.
