參閱圖1、圖11及圖12，該鉸鏈10能使該等機殼11在該等接合板12彼此相向的一內折疊位置、該等機殼11呈展開狀態的一展開位置與該等機殼11的基壁111彼此相向的一外折疊位置間轉動，意即該折疊式螢幕裝置100能夠自0度展開至180度甚至360度。該等機殼11在該內折疊位置及該展開位置之間轉動，以及在該展開位置及該外折疊位置之間轉動的過程中，該螢幕單元2是活動地容置於該等軌道槽141。Referring to Figures 1, 11 and 12, the hinge 10 enables the casings 11 to be in an inner folded position where the joint plates 12 face each other, an unfolded position in which the casings 11 are in an unfolded state, and the machines The base walls 111 of the casing 11 rotate between an outer folding position facing each other, which means that the foldable screen device 100 can be unfolded from 0 degrees to 180 degrees or even 360 degrees. When the casings 11 rotate between the inner folded position and the unfolded position, and in the process of rotating between the unfolded position and the outer folded position, the screen unit 2 is movably accommodated in the track grooves 141 .

參閱圖2、圖13至圖15，在該內折疊位置時，該等側支撐板45、該等外支撐單元41、該等中支撐單元42及該內支撐單元43的各支撐管的表面共同界定出如水滴狀的空間可足夠供該螢幕單元2容置而不會過度彎折或壓制該螢幕單元2。接著參閱圖1、圖8、圖10、圖16及圖17，由該內折疊位置轉換至該展開位置時，該等機殼11及該等連動支架51向下轉動，帶動該等卡抵件55沿著該等收容塊32的外表面移動而最終受該卡抵彈性件56的彈性力推動以卡抵於對應的該凹槽321，提供一固鎖的手感使該等機殼11不會因些微外力即脫離該展開位置，便於使用者觀看。而在此同時，該等推抵件53也受該推抵彈性件54的彈性力而推動該等推抵塊24而帶動該等滑板22分別遠離該等連動支架51移動，藉此可對該可撓式螢幕21提供向外拉扯的力，使該可撓式螢幕21能更快的趨於平坦的狀態。參閱圖2、圖18至圖20，由該展開位置轉換至該外折疊位置時，該等外支撐單元41的該等第一外支撐管412相對於該中央外支撐管411向下樞轉且該等第二外支撐管413分別相對於該等第一外支撐管412向下樞轉，該等中支撐單元42的該等第一中支撐管422相對於該中央中支撐管421向下樞轉且該等第二中支撐管423分別相對於該等第一中支撐管422向下樞轉，該內支撐單元43的該等第一內支撐管432相對於該中央內支撐管431向下樞轉且該等第二內支撐管433分別相對於該等第一內支撐管432向下樞轉，且該等扭力片單元44彼此緊密層疊在轉動時產生的扭力能夠穩固地維持該等機殼11位於該外折疊位置，此時該等外支撐單元41、該等中支撐單元42及該內支撐單元43的各支撐管的表面共同形成一呈半圓弧形的支撐面以支撐該螢幕單元2，且因該螢幕單元2相對於該等機殼11活動，該可撓式螢幕21能夠緊密地貼合上述的支撐面而不會受擠壓變形而造成損壞。再搭配參閱圖2、圖13至圖15，同樣地，當折疊式螢幕裝置100使用完畢後，使用者可收合該等機殼11使該等機殼11轉換至該內折疊位置，由該展開位置轉換至該內折疊位置時，該等外支撐單元41的該等第一外支撐管412相對於該中央外支撐管411向上樞轉且該等第二外支撐管413分別相對於該等第一外支撐管412向上樞轉，該等中支撐單元42的該等第一中支撐管422相對於該中央中支撐管421向上樞轉且該等第二中支撐管423分別相對於該等第一中支撐管422向上樞轉，該內支撐單元43的該等第一內支撐管432相對於該中央內支撐管431向上樞轉且該等第二內支撐管433分別相對於該等第一內支撐管432向上樞轉，且該等扭力片單元44彼此緊密層疊在轉動時產生的扭力同樣能夠穩固地維持該等機殼11位於該內折疊位置，此時該螢幕單元2容置於前述如水滴狀的空間而不會過度彎折該螢幕單元2而造成損壞。Referring to Figures 2 and 13-15, in the inner folded position, the surface of the side support plates 45, the outer support units 41, the middle support units 42, and the support tubes of the inner support unit 43 are common The space defined as a drop shape can be enough for the screen unit 2 to be accommodated without excessively bending or pressing the screen unit 2. Next, referring to Figure 1, Figure 8, Figure 10, Figure 16 and Figure 17, when switching from the inner folding position to the unfolding position, the casings 11 and the linkage brackets 51 rotate downward to drive the retaining members 55 moves along the outer surface of the accommodating blocks 32 and is finally pushed by the elastic force of the snapping elastic member 56 to snap against the corresponding groove 321, providing a lock feel so that the casings 11 will not Due to a slight external force, it leaves the unfolded position, which is convenient for users to watch. At the same time, the pushing members 53 are also pushed by the elastic force of the pushing elastic member 54 to push the pushing blocks 24 to drive the sliding plates 22 to move away from the linkage brackets 51, so that the The flexible screen 21 provides an outward pulling force, so that the flexible screen 21 can tend to a flat state more quickly. Referring to Figures 2 and 18 to 20, when transitioning from the unfolded position to the outer folded position, the first outer support tubes 412 of the outer support units 41 pivot downward relative to the central outer support tube 411 and The second outer support tubes 413 respectively pivot downward relative to the first outer support tubes 412, and the first middle support tubes 422 of the middle support units 42 pivot downward relative to the central middle support tube 421 And the second middle support tubes 423 respectively pivot downward relative to the first middle support tubes 422, and the first inner support tubes 432 of the inner support unit 43 are downward relative to the central inner support tube 431 And the second inner support tubes 433 respectively pivot downward relative to the first inner support tubes 432, and the torsion plate units 44 are closely stacked on each other and the torsion force generated when rotating can stably maintain the mechanisms. The shell 11 is located in the outer folding position. At this time, the surfaces of the outer support units 41, the middle support units 42 and the support tubes of the inner support unit 43 together form a semi-circular arc-shaped support surface to support the screen unit 2. Because the screen unit 2 is movable relative to the casings 11, the flexible screen 21 can be closely attached to the above-mentioned supporting surface without being squeezed and deformed to cause damage. Refer to Figure 2 and Figure 13 to Figure 15. Similarly, when the foldable screen device 100 is used, the user can fold the casings 11 so that the casings 11 can be converted to the inner folding position. When the unfolded position is converted to the inner folded position, the first outer support tubes 412 of the outer support units 41 pivot upward relative to the central outer support tube 411, and the second outer support tubes 413 respectively relative to the The first outer support tubes 412 pivot upward, the first middle support tubes 422 of the middle support units 42 pivot upward relative to the central middle support tube 421, and the second middle support tubes 423 are respectively relative to the The first middle support tube 422 pivots upward, the first inner support tubes 432 of the inner support unit 43 pivot upward relative to the central inner support tube 431, and the second inner support tubes 433 respectively relative to the first inner support tubes 431. An inner supporting tube 432 pivots upward, and the torsion force generated when the torsion sheet units 44 are closely stacked on each other can also stably maintain the casings 11 in the inner folded position. At this time, the screen unit 2 is accommodated The aforementioned water-drop-shaped space will not bend the screen unit 2 excessively and cause damage.

綜上所述，本新型鉸鏈10藉由該扭力模組4的該等外支撐單元41的該等第一外支撐管412相對於該中央外支撐管411向下樞轉且該等第二外支撐管413分別相對於該等第一外支撐管412向下樞轉，該等中支撐單元42的該等第一中支撐管422相對於該中央中支撐管421向下樞轉且該等第二中支撐管423分別相對於該等第一中支撐管422向下樞轉，該內支撐單元43的該等第一內支撐管432相對於該中央內支撐管431向下樞轉且該等第二內支撐管433分別相對於該等第一內支撐管432向下樞轉，以共同形成一呈半圓弧形的支撐面以支撐該螢幕單元2，避免該螢幕單元2因機殼11產生的內外徑差而造成的拉扯擠壓進而損壞，故確實能達成本新型之目的。In summary, the hinge 10 of the present invention pivots downward relative to the central outer support tube 411 by the first outer support tubes 412 of the outer support units 41 of the torsion module 4 and the second outer support tubes 411 The support tubes 413 pivot downward relative to the first outer support tubes 412, respectively, the first middle support tubes 422 of the middle support units 42 pivot downward relative to the central middle support tube 421, and the second The two middle support tubes 423 respectively pivot downward relative to the first middle support tubes 422, the first inner support tubes 432 of the inner support unit 43 pivot downward relative to the central inner support tube 431, and the The second inner support tubes 433 respectively pivot downward relative to the first inner support tubes 432 to jointly form a semi-circular arc-shaped support surface to support the screen unit 2 and prevent the screen unit 2 from being generated by the casing 11 Pulling and squeezing caused by the difference between the inner and outer diameters of the steel and then damaged, it can indeed achieve the purpose of new cost.
