Furthermore, in some embodiments, the pivoting portion 131 may be a cam shaft.

如圖1B與圖2A所示，第一主體111與第二主體112皆設置於兩個限位部139之間。由於圖2A與圖2B皆描繪位於一個第一樞轉構件130與一個第二樞轉構件140處的支撐組件110部分內部，因此圖2A與圖2B顯示單一個限位部139與兩個樞轉部131，而其他限位部139與樞轉部131未繪示於圖2A與圖2B中。As shown in FIG. 1B and FIG. 2A , the first main body 111 and the second main body 112 are both disposed between the two limiting portions 139 . Since FIG. 2A and FIG. 2B both describe the inside of the support assembly 110 at a first pivot member 130 and a second pivot member 140, FIG. 2A and FIG. 2B show a single stopper 139 and two pivots. portion 131, while other limiting portions 139 and pivoting portions 131 are not shown in FIG. 2A and FIG. 2B.

第一樞轉構件130更包括多根轉軸132。這些轉軸132分別穿透這些樞轉部131，且各自具有一根第一軸心A13。兩個樞轉部131能沿著兩根轉軸132而彼此相對旋轉，如圖2B所示。此外，這些轉軸132也分別穿透這些限位部139。具體而言，每一個限位部139具有多個孔洞139h，而在同一個限位部139中，這些孔洞139h與溝槽139t連通。兩根轉軸132分別貫穿兩個孔洞139h與兩個樞轉部131，所以這些彼此連接的樞轉部131能相對於限位部139旋轉。The first pivoting member 130 further includes a plurality of rotating shafts 132 . The rotating shafts 132 pass through the pivoting portions 131 respectively, and each has a first axis A13 . The two pivoting parts 131 can rotate relative to each other along the two rotating shafts 132 , as shown in FIG. 2B . In addition, the rotating shafts 132 also respectively pass through the limiting portions 139 . Specifically, each limiting portion 139 has a plurality of holes 139h, and in the same limiting portion 139, these holes 139h communicate with the groove 139t. The two rotating shafts 132 pass through the two holes 139h and the two pivoting portions 131 respectively, so the pivoting portions 131 connected to each other can rotate relative to the limiting portion 139 .

因此，每一個樞轉部131能沿著第一軸心A13而旋轉，而相鄰的兩個樞轉部131沿著不同方向旋轉。以圖2B為例，右邊的樞轉部131能逆時針旋轉，而左邊的樞轉部131能順時針旋轉。此外，每一個樞轉部131可具有齒輪端（geared end）131e，所以相鄰的兩個樞轉部131能透過這些齒輪端131e而彼此嚙合並能同時轉動。Therefore, each pivoting portion 131 can rotate along the first axis A13 , and two adjacent pivoting portions 131 can rotate along different directions. Taking FIG. 2B as an example, the right pivoting part 131 can rotate counterclockwise, while the left pivoting part 131 can rotate clockwise. In addition, each pivoting portion 131 may have a geared end 131e, so two adjacent pivoting portions 131 can engage with each other through these geared ends 131e and can rotate simultaneously.

另外，限位部139能限制各個樞轉部131的旋轉。具體而言，當摺疊式顯示裝置100處於第二狀態時，限位部139的底部139b能阻擋相鄰兩個樞轉部131分別在不同方向上的旋轉。以圖2A與圖2B為例，限位部139的底部139b能阻擋右邊的樞轉部131向順時針方向旋轉，以及阻擋左邊的樞轉部131向逆時針旋轉，以使限位部139能防止柔性顯示面板190因過度伸展（overstretching）而損壞。In addition, the limiting portion 139 can limit the rotation of each pivoting portion 131 . Specifically, when the foldable display device 100 is in the second state, the bottom 139b of the limiting portion 139 can block two adjacent pivoting portions 131 from rotating in different directions. 2A and 2B as an example, the bottom 139b of the limiting portion 139 can block the right pivoting portion 131 from rotating clockwise, and prevent the left pivoting portion 131 from rotating counterclockwise, so that the limiting portion 139 can Prevent the flexible display panel 190 from being damaged due to overstretching.

當摺疊或攤平支撐組件110時，樞轉部131能沿著第一軸心A13旋轉。由於位在同一個限位部139內的這些樞轉部131分別連接第一主體111與第二主體112，因此第一主體111與第二主體112應能分別沿著第一軸心A13而旋轉。When the supporting assembly 110 is folded or flattened, the pivoting portion 131 can rotate along the first axis A13. Since the pivoting parts 131 located in the same limiting part 139 are respectively connected to the first body 111 and the second body 112, the first body 111 and the second body 112 should be able to rotate along the first axis A13 respectively. .

請參閱圖1B、圖2A與圖2B，在支撐組件110相對兩側，第二樞轉構件140更包括一對樞轉部141。當摺疊式顯示裝置100處於第二狀態時，第四主體114位於第二主體112與第三主體113之間，且第四主體114也位於這對樞轉部141之間。第四主體114使用兩根轉軸142而連接於樞轉部141的第一樞接件141a與第二樞接件141b，其中第一樞接件141a與第二樞接件141b可以是凸軸。轉軸142設置於第一樞接件141a與第二樞接件141b的孔洞中，或是於部分第一樞接件141a與第二樞接件141b中。轉軸142設置於第四主體114中，以在摺疊期間，控制第四主體114的旋轉。Please refer to FIG. 1B , FIG. 2A and FIG. 2B , on opposite sides of the support assembly 110 , the second pivot member 140 further includes a pair of pivot portions 141 . When the foldable display device 100 is in the second state, the fourth body 114 is located between the second body 112 and the third body 113 , and the fourth body 114 is also located between the pair of pivoting parts 141 . The fourth main body 114 is connected to the first pivotal member 141 a and the second pivotal member 141 b of the pivoting portion 141 using two rotating shafts 142 , wherein the first pivotal member 141 a and the second pivotal member 141 b may be protruding shafts. The rotating shaft 142 is disposed in the holes of the first pivotal member 141a and the second pivotal member 141b, or in a part of the first pivotal member 141a and the second pivotal member 141b. The rotating shaft 142 is disposed in the fourth body 114 to control the rotation of the fourth body 114 during folding.

需注意的是，由於圖2A與圖2B描繪位於一個第一樞轉構件130與一個第二樞轉構件140處的支撐組件110部分內部，因此圖2A與圖2B顯示單一個樞轉部141。其他樞轉部141未繪示於圖2A與圖2B中。此外，圖2B描繪出具有第一樞接件141a與第二樞接件141b的樞轉部141。It should be noted that, since FIG. 2A and FIG. 2B depict a portion of the support assembly 110 inside a first pivot member 130 and a second pivot member 140 , FIG. 2A and FIG. 2B show a single pivot portion 141 . Other pivoting parts 141 are not shown in FIG. 2A and FIG. 2B . In addition, FIG. 2B depicts the pivoting portion 141 having a first pivoting member 141a and a second pivoting member 141b.

這對樞轉部141每一個包括第一樞接件141a與第二樞接件141b，而第二樞轉構件140可以更包括多個轉軸142。這些轉軸142分別穿透第一樞接件141a與第二樞接件141b，並且各自具有第二軸心A14。在本實施方式中，第二主體112與第三主體113為雙軸樞轉設計。Each of the pair of pivoting parts 141 includes a first pivoting member 141 a and a second pivoting member 141 b, and the second pivoting member 140 may further include a plurality of rotating shafts 142 . The rotating shafts 142 pass through the first pivotal member 141 a and the second pivotal member 141 b respectively, and each has a second axis A14 . In this embodiment, the second body 112 and the third body 113 are designed to pivot with two axes.

在一些實施方式中，第一樞接件141a與第三主體113可為一體成型，而第二樞接件141b與第二主體112可為一體成型。因此，當摺疊或攤平摺疊式顯示裝置100（或支撐組件110）時，第三主體113能沿著第二軸心A14而相對於第二主體112與第四主體114旋轉，其中第二軸心A14經由第二樞轉構件140而穿過第一樞接件141a。同樣地，第二主體112與第三主體113僅沿著第二軸心A14而旋轉。In some embodiments, the first pivot member 141 a and the third body 113 may be integrally formed, and the second pivot member 141 b and the second body 112 may be integrally formed. Therefore, when the foldable display device 100 (or the support assembly 110 ) is folded or flattened, the third body 113 can rotate relative to the second body 112 and the fourth body 114 along the second axis A14, wherein the second axis The core A14 passes through the first pivot member 141 a via the second pivot member 140 . Likewise, the second body 112 and the third body 113 only rotate along the second axis A14.

請參閱圖2B與圖2C，圖2C是省略圖2B的樞轉部131、141。第一主體111與第二主體112還可各具有橢圓孔115，使得兩樞轉部131可分別插設於此兩橢圓孔115。Please refer to FIG. 2B and FIG. 2C . FIG. 2C omits the pivoting parts 131 and 141 of FIG. 2B . The first main body 111 and the second main body 112 can also each have an elliptical hole 115 , so that the two pivoting parts 131 can be respectively inserted into the two elliptical holes 115 .

在一些實施例中，各個第一樞接件141a具有凸塊P14，而各個第二樞接件141b具有凹槽R14。當摺疊式顯示裝置100（或支撐組件110）處於第二狀態，凸塊P14會***凹槽R14內。相反地，當摺疊式顯示裝置100（或支撐組件110）處於第一狀態時，凸塊P14會離開凹槽R14。此外，第一軸心A13與第二軸心A14皆能沿著一方向而延伸。換句話說，第一軸心A13在可允許的公差範圍內，可實質上平行於第二軸心A14。In some embodiments, each first pivot member 141a has a protrusion P14, and each second pivot member 141b has a groove R14. When the foldable display device 100 (or the support assembly 110 ) is in the second state, the protrusion P14 will be inserted into the groove R14 . Conversely, when the foldable display device 100 (or the supporting assembly 110 ) is in the first state, the protrusion P14 will leave the groove R14 . In addition, both the first axis A13 and the second axis A14 can extend along a direction. In other words, the first axis A13 can be substantially parallel to the second axis A14 within an allowable tolerance range.

當在第二狀態下，凸塊P14***凹槽R14內時，第一樞接件141a與第二樞接件141b每一者的轉動會受到限制。具體而言，從圖2B可以明顯得知在第二狀態下，在凹槽R14內的凸塊P14會抵靠（abut）於第二樞接件141b，也就是說，第一樞接件141a與第二樞接件141b會彼此抵靠，以使在圖2B中，第一樞接件141a不能沿著順時針旋轉，而第二樞接件141b不能沿著逆時針旋轉，從而限制各個第一樞接件141a與第二樞接件141b的旋轉。When the protrusion P14 is inserted into the groove R14 in the second state, the rotation of each of the first pivotal member 141 a and the second pivotal member 141 b is restricted. Specifically, it can be clearly seen from FIG. 2B that in the second state, the protrusion P14 in the groove R14 will abut against (abut) the second pivotal member 141b, that is, the first pivotal member 141a and the second pivot member 141b will abut against each other, so that in FIG. 2B, the first pivot member 141a cannot rotate clockwise, and the second pivot member 141b cannot rotate counterclockwise, thereby limiting each first The rotation of the first pivotal member 141a and the second pivotal member 141b.

圖3A是摺疊圖1A中的摺疊式顯示裝置100的立體示意圖，其中圖3A省略一些元件，例如限位部139與阻擋件149。請參閱圖3A，當摺疊攤平的摺疊式顯示裝置100時，第二主體112能透過第一樞轉構件130而沿著轉軸132旋轉。此外，如圖3A所示，當凸塊P14***於凹槽R14內時，第一樞接件141a的側邊能切齊於第二樞接件141b的側邊。FIG. 3A is a schematic perspective view of folding the foldable display device 100 in FIG. 1A , where some elements, such as the limiting portion 139 and the blocking member 149 , are omitted in FIG. 3A . Please refer to FIG. 3A , when the foldable display device 100 is folded flat, the second body 112 can rotate along the rotating shaft 132 through the first pivoting member 130 . In addition, as shown in FIG. 3A , when the protrusion P14 is inserted into the groove R14 , the side of the first pivotal component 141 a can be aligned with the side of the second pivotal component 141 b.

圖3B是圖2B中處於第一狀態下的被摺疊的支撐組件110的側視示意圖，其中圖3B主要描繪第一狀態下的支撐組件110的內部。請參閱圖3B，從圖3B可以明顯得知，在第一狀態下，凸塊P14離開凹槽R14。此外，圖3B中被摺疊的支撐組件110具有P形側邊，其中第一主體111與第三主體113彼此相對設置。FIG. 3B is a schematic side view of the folded support assembly 110 in the first state in FIG. 2B , wherein FIG. 3B mainly depicts the interior of the support assembly 110 in the first state. Referring to FIG. 3B , it can be clearly seen from FIG. 3B that in the first state, the bump P14 leaves the groove R14 . In addition, the folded support assembly 110 in FIG. 3B has a P-shaped side, wherein the first body 111 and the third body 113 are disposed opposite to each other.

圖3C是處於第一狀態下的摺疊式顯示裝置100的剖面示意圖，其中柔性顯示面板190可透過膠材而貼合於第一表面111s上、第二表面112s上與第三表面113s上。請參閱圖3C，當被摺疊的摺疊式顯示裝置100（或被摺疊的支撐組件110）處於第一狀態時，第一表面111s、第二表面112s、第三表面113s與第四表面114s不共平面，且柔性顯示面板190被摺疊。因此，藉由第二樞轉構件140，摺疊式顯示裝置100及其支撐組件110兩者能在第二狀態（如圖1A與圖1B所示）與第一狀態之間切換。3C is a schematic cross-sectional view of the foldable display device 100 in the first state, wherein the flexible display panel 190 can be pasted on the first surface 111s, the second surface 112s and the third surface 113s through adhesive materials. Please refer to FIG. 3C, when the folded display device 100 (or the folded support assembly 110) is in the first state, the first surface 111s, the second surface 112s, the third surface 113s and the fourth surface 114s are not in common. plane, and the flexible display panel 190 is folded. Therefore, both the foldable display device 100 and its support assembly 110 can be switched between the second state (as shown in FIGS. 1A and 1B ) and the first state by the second pivoting member 140 .

在第一狀態下，第一間隙G1形成於第一表面111s與第二表面112s之間，而第二間隙G2形成於第一表面111s與第三表面113s之間。如圖3C所示，第一間隙G1的寬度明顯大於第二間隙G2的寬度。第一間隙G1的寬度從第一樞轉構件130至第二樞轉構件140而漸縮。由於第一主體111與第三主體113彼此相對設置，因此第一主體111與第三主體113基本上能彼此堆疊，而處於第一狀態下的摺疊式顯示裝置100或支撐組件110具有第一厚度TH1與第二厚度TH2，其中第一厚度TH1明顯薄於第二厚度TH2。In the first state, the first gap G1 is formed between the first surface 111s and the second surface 112s, and the second gap G2 is formed between the first surface 111s and the third surface 113s. As shown in FIG. 3C , the width of the first gap G1 is obviously larger than the width of the second gap G2 . The width of the first gap G1 is tapered from the first pivot member 130 to the second pivot member 140 . Since the first body 111 and the third body 113 are disposed opposite to each other, the first body 111 and the third body 113 can basically be stacked on each other, and the foldable display device 100 or the support assembly 110 in the first state has a first thickness TH1 and a second thickness TH2, wherein the first thickness TH1 is obviously thinner than the second thickness TH2.

如圖3C所示，第一厚度TH1從第一主體111延伸至第三主體113，而第二厚度TH2從第一主體111延伸至第二主體112，其中第二厚度TH2也可從鄰接第一樞轉構件130的第二主體112邊緣至第三主體113而遞減。由此可知，被摺疊的摺疊式顯示裝置100（或被摺疊的支撐組件110）的側邊能形成“P”字形，如圖3C所示。As shown in FIG. 3C, the first thickness TH1 extends from the first body 111 to the third body 113, and the second thickness TH2 extends from the first body 111 to the second body 112, wherein the second thickness TH2 can also extend from the adjacent first body The pivoting member 130 decreases gradually from the second body 112 edge to the third body 113 . It can be seen from this that the side of the folded foldable display device 100 (or the folded support assembly 110 ) can form a "P" shape, as shown in FIG. 3C .

在第一狀態下，摺疊式顯示裝置100與支撐組件110每一者具有銳夾角A12，其形成於第一表面111s與第二表面112s之間，其中銳夾角A12相對於第一樞轉構件130。因此，第一樞轉構件130的寬度W4能相對於第二主體112與第一主體111而傾斜。換句話說，寬度W4不垂直於第一表面111s與第二表面112s，所以傾斜的寬度W4能有助於減少摺疊式顯示裝置100整體厚度，從而滿足行動裝置方便攜帶的設計。In the first state, each of the foldable display device 100 and the support assembly 110 has an acute angle A12 formed between the first surface 111s and the second surface 112s, wherein the acute angle A12 is relative to the first pivoting member 130 . Therefore, the width W4 of the first pivoting member 130 can be inclined relative to the second body 112 and the first body 111 . In other words, the width W4 is not perpendicular to the first surface 111s and the second surface 112s, so the inclined width W4 can help to reduce the overall thickness of the foldable display device 100, so as to meet the portable design of mobile devices.

在較佳實施例中，處於第一狀態的柔性顯示面板190能具有介於1公厘至4公厘之間(例如1.76公厘)的間隙寬度W3，其中間隙寬度W3位於第一表面111s與第三表面113s之間。由於第一間隙G1的寬度W1大於第二間隙G2的寬度W2，因此第一狀態下被摺疊的柔性顯示面板190可以更具有被第一樞轉構件130、第一主體111與第二主體112圍繞的彎曲摺疊部191。In a preferred embodiment, the flexible display panel 190 in the first state can have a gap width W3 between 1 mm to 4 mm (for example, 1.76 mm), wherein the gap width W3 is located between the first surface 111s and the first surface 111s. between the third surfaces 113s. Since the width W1 of the first gap G1 is larger than the width W2 of the second gap G2, the folded flexible display panel 190 in the first state can be more surrounded by the first pivoting member 130 , the first body 111 and the second body 112 The bent folded portion 191.

柔性顯示面板190的彎曲摺疊部191具有曲率半徑R19，其中曲率半徑R19大於間隙寬度W3，且曲率半徑R19介於1公厘至7.5公厘之間，例如約4公厘(如4.33公厘)。因此，支撐組件110無法將柔性顯示面板190摺平，以避免破壞柔性顯示面板190。The curved and folded portion 191 of the flexible display panel 190 has a curvature radius R19, wherein the curvature radius R19 is greater than the gap width W3, and the curvature radius R19 is between 1 mm to 7.5 mm, for example about 4 mm (such as 4.33 mm) . Therefore, the support assembly 110 cannot fold the flexible display panel 190 flat to avoid damaging the flexible display panel 190 .

圖3D是處於第一狀態下的柔性顯示面板190的示意圖，例如圖3C省略支撐組件110時的柔性顯示面板190。同時參閱圖3C與圖3D，當圖3C的摺疊式顯示裝置100處於第一狀態時，柔性顯示面板190在第三主體113的部分與在第二主體112的部分之間形成的第一夾角θ1在145度至165度的範圍中(例如154度)，而柔性顯示面板190在第一主體111與第二主體112任一者上的部分與水平線L之間形成的第二夾角θ2在95度至115度的範圍中(例如103度)。FIG. 3D is a schematic diagram of the flexible display panel 190 in the first state, for example, the flexible display panel 190 when the support assembly 110 is omitted in FIG. 3C . Referring to FIG. 3C and FIG. 3D at the same time, when the foldable display device 100 in FIG. 3C is in the first state, the flexible display panel 190 forms a first angle θ1 between the part of the third body 113 and the part of the second body 112 In the range of 145 degrees to 165 degrees (for example, 154 degrees), and the second angle θ2 formed between the part of the flexible display panel 190 on any one of the first body 111 and the second body 112 and the horizontal line L is 95 degrees to a range of 115 degrees (eg 103 degrees).

圖4A是圖1A中的摺疊式顯示裝置100的另一視角(從背側看)的立體示意圖，而圖4B是圖4A中省略一些外殼的支撐組件110的立體示意圖。這些描繪於圖4A的外殼未被標示。請參閱圖4A與圖4B，支撐組件110可以更包括設置於第三主體113中的阻擋件160，其鄰接第四主體114。FIG. 4A is a perspective view of the foldable display device 100 in FIG. 1A from another perspective (viewed from the back side), and FIG. 4B is a perspective view of the support assembly 110 in FIG. 4A omitting some shells. These housings depicted in Figure 4A are not labeled. Referring to FIG. 4A and FIG. 4B , the support assembly 110 may further include a blocking member 160 disposed in the third body 113 and adjacent to the fourth body 114 .

圖4C是圖4B中的支撐組件110的局部立體示意圖。請參閱圖4B與圖4C，阻擋件160包括滑動部161與至少一個復位元件162。滑動部161可移動地設置於第三主體113，所以滑動部161能從第三主體113移動至第四主體114，並回到第三主體113，其中第四主體114可位於柔性顯示面板190與滑動部161之間。此外，滑動部161能沿著第三主體113的內表面113i滑動。FIG. 4C is a partial perspective view of the support assembly 110 in FIG. 4B . Please refer to FIG. 4B and FIG. 4C , the blocking member 160 includes a sliding portion 161 and at least one reset element 162 . The sliding part 161 is movably disposed on the third body 113, so the sliding part 161 can move from the third body 113 to the fourth body 114, and back to the third body 113, wherein the fourth body 114 can be located between the flexible display panel 190 and Between the sliding parts 161. In addition, the sliding part 161 can slide along the inner surface 113 i of the third body 113 .

在圖4C所示的較佳實施例中，阻擋件160可包括多個復位元件162，其中每個復位元件162連接滑動部161，而這些復位元件162彼此並列設置。不過，在其他較佳實施例中，阻擋件160內的復位元件162之數量可以僅為一個，以使阻擋件160所包括的復位元件162之數量不限制為兩個或兩個以上。In the preferred embodiment shown in FIG. 4C , the blocking member 160 may include a plurality of reset elements 162 , wherein each reset element 162 is connected to the sliding portion 161 , and these reset elements 162 are arranged side by side. However, in other preferred embodiments, the number of reset elements 162 in the blocking element 160 may be only one, so that the number of reset elements 162 included in the blocking element 160 is not limited to two or more than two.

這些復位元件162可為彈簧，例如線圈彈簧（coil spring）或扭力彈簧（torsion spring）。在較佳實施例中，每個復位元件162是線圈彈簧，所以復位元件162能延展與收縮。如此，這些復位元件162能使滑動部161移動至第四主體114，因此當攤平的摺疊式顯示裝置100處於第二狀態時，滑動部161從第三主體113延伸至第四主體114。The restoring elements 162 can be springs, such as coil springs or torsion springs. In a preferred embodiment, each reset element 162 is a coil spring, so the reset element 162 can expand and contract. In this way, the reset elements 162 can make the sliding part 161 move to the fourth body 114 , so when the folded display device 100 is in the second state, the sliding part 161 extends from the third body 113 to the fourth body 114 .

當滑動部161延伸至第四主體114時，滑動部161可接觸第四主體114，以使滑動部161能阻擋第四主體114與第三主體113之間的相對旋轉。因此，滑動部161能禁止第二主體112與第三主體113之間的相對旋轉，以移除第二主體112與第三主體113的背隙（backlash），並防止摺疊式顯示裝置100突然間的摺疊，從而在觀看或閱覽摺疊式顯示裝置100時，有助於使用摺疊式顯示裝置100更加順手。When the sliding part 161 extends to the fourth body 114 , the sliding part 161 can contact the fourth body 114 so that the sliding part 161 can block the relative rotation between the fourth body 114 and the third body 113 . Therefore, the sliding part 161 can prohibit the relative rotation between the second body 112 and the third body 113 to remove the backlash between the second body 112 and the third body 113 and prevent the folding display device 100 from suddenly The folding of the foldable display device 100 helps to use the foldable display device 100 more smoothly when watching or viewing the foldable display device 100 .

The main body 161m is movably disposed on the third main body 113 and connected between the extending sections 161s. The main body portion 161m may have a wedge-shaped end 161e. When the sliding part 161 extends to the fourth body 114 , the wedge-shaped end 161 e can contact the fourth body 114 . The main body 161m may further have two grooves 161r, and the long stick 161b is connected to the main body 161m and located in the grooves 161r. Each long stick 161b is inserted into a reset element 162, wherein all the long sticks 161b extend towards the same direction and are arranged side by side.

此外，第三主體113具有阻擋凸塊113b，其中阻擋凸塊113b能限制並禁止滑動部161的移動。阻擋凸塊113b具有多個溝部（grooves，未標示）。長棍件161b能分別穿過這些溝部，並且相對於阻擋凸塊113b移動。這些復位元件162被局限於這些凹槽161r內。這些延伸段161s每個具有開口，而第三主體113更具有兩個限位凸件B13，其例如可以是螺絲。限位凸件B13分別位於這些開口內，以使限位凸件B13能限制滑動部161的移動。In addition, the third body 113 has a blocking protrusion 113 b, wherein the blocking protrusion 113 b can limit and prohibit the movement of the sliding part 161 . The blocking protrusion 113b has a plurality of grooves (grooves, not shown). The long rods 161b can respectively pass through these grooves and move relative to the blocking protrusions 113b. The reset elements 162 are confined within the grooves 161r. Each of the extension sections 161s has an opening, and the third body 113 further has two limiting protrusions B13, which may be screws, for example. The limiting protrusions B13 are respectively located in these openings, so that the limiting protrusions B13 can limit the movement of the sliding part 161 .

In addition, the structures of the first body 511 , the second body 512 and the first pivot member 530 are substantially the same as those of the first body 111 , the second body 112 and the first pivot member 130 respectively.

圖6A是圖5A中的摺疊式顯示裝置500的另一視角(從背側看)的立體示意圖，而圖6B是圖6A中省略一些外殼的支撐組件510的立體示意圖。具體而言，圖6A描繪摺疊式顯示裝置500的底部，其中第一主體511包括外殼511c，第二主體512包括外殼512c，而第三主體513包括外殼513c。圖6B省略這些外殼511c、512c與513c。FIG. 6A is a schematic perspective view of another viewing angle (viewed from the back) of the foldable display device 500 in FIG. 5A , and FIG. 6B is a schematic perspective view of the support assembly 510 in FIG. 6A omitting some shells. Specifically, FIG. 6A depicts the bottom of the foldable display device 500, wherein the first body 511 includes a housing 511c, the second body 512 includes a housing 512c, and the third body 513 includes a housing 513c. FIG. 6B omits these shells 511c, 512c and 513c.

請參閱圖6A與圖6B，支撐組件510更包括阻擋件560，其包括滑動部561與至少一個復位元件162。支撐板543位於第二主體512與第三主體513之間。滑動部561可移動地設置於第三主體513，以使滑動部561能從第三主體513移動至支撐板543，並回到第三主體513。此外，滑動部561能在第三主體513的凹陷513i內滑動。Please refer to FIG. 6A and FIG. 6B , the support assembly 510 further includes a blocking member 560 including a sliding portion 561 and at least one reset element 162 . The supporting plate 543 is located between the second body 512 and the third body 513 . The sliding part 561 is movably disposed on the third body 513 so that the sliding part 561 can move from the third body 513 to the support plate 543 and back to the third body 513 . In addition, the sliding part 561 can slide in the recess 513i of the third body 513 .

在較佳實施例中，阻擋件560可包括多個復位元件162，其中每個並排的復位元件162連接滑動部561。不過，在其他較佳實施例中，阻擋件560可包括單一個連接滑動部561的復位元件162。因此，阻擋件560所包括的復位元件162之數量可以僅為一個，且不限制是兩個或兩個以上。In a preferred embodiment, the blocking member 560 may include a plurality of reset elements 162 , wherein each parallel reset element 162 is connected to the sliding part 561 . However, in other preferred embodiments, the blocking member 560 may include a single reset element 162 connected to the sliding portion 561 . Therefore, the number of reset elements 162 included in the blocking member 560 may be only one, and is not limited to two or more than two.

這些復位元件162也能使滑動部561移動至支撐板543，因此當攤平的摺疊式顯示裝置500處於第二狀態時，滑動部561能從第三主體513延伸至支撐板543。當滑動部561延伸至支撐板543時，滑動部561也能阻擋支撐板543與第三主體513之間的相對旋轉。因此，滑動部561能禁止第二主體512與第三主體513之間的相對旋轉，以防止摺疊式顯示裝置500突然間的摺疊，從而在觀看或閱覽摺疊式顯示裝置500時，有助於使用摺疊式顯示裝置500更加順手。The resetting elements 162 can also move the sliding part 561 to the supporting plate 543 , so when the flattened foldable display device 500 is in the second state, the sliding part 561 can extend from the third body 513 to the supporting plate 543 . When the sliding portion 561 extends to the supporting plate 543 , the sliding portion 561 can also block the relative rotation between the supporting plate 543 and the third body 513 . Therefore, the sliding part 561 can prohibit the relative rotation between the second body 512 and the third body 513, so as to prevent the folding display device 500 from being folded suddenly, thereby facilitating the use of the folding display device 500 when watching or reading.

The blocking protrusion 513b and the limiting protrusions B53 are located in the recess 513i. The blocking protrusion 513b having a plurality of grooves can restrict and prohibit the movement of the sliding bar 561m. The long sticks 561b can respectively pass through the grooves of the blocking protrusions 513b and move relative to the blocking protrusions 513b. The reset element 162 is confined within the groove 561r. Each of the extending sections 561s has an opening, wherein the limiting protrusions B53 are respectively located in the openings, so that the limiting protrusions B53 can limit the movement of the sliding part 161 .

請參閱圖6D，有別於滑動部161與第三主體113，阻擋件560可以更包括齒輪563，而第三主體513可以更具有齒輪架513g，其中齒輪架513g能與齒輪563嚙合。齒輪架513g可位於齒輪563與其中一根長棍件561b之間，而齒輪563能設置於滑動條561m與齒輪架513g之間。此外，滑動條561m具有齒邊，而齒輪563也能與此齒邊嚙合。當滑動條561m相對於第三主體513移動時，齒輪563會移動。Please refer to FIG. 6D , different from the sliding part 161 and the third body 113 , the blocking member 560 may further include a gear 563 , and the third body 513 may further have a gear frame 513g, wherein the gear frame 513g can engage with the gear 563 .

圖7A是圖6B中的支撐組件510的局部立體示意圖，而圖7B是摺疊圖5A中的摺疊式顯示裝置500的立體示意圖。請參閱圖7A與圖7B，有別於前述第二樞轉構件140，第二樞轉構件540更包括一對樞轉部541(在支撐組件510的相對兩側，見圖6B)與兩根轉軸542，而支撐板543設置於這對樞轉部541之間，且各個樞轉部541包括兩個連接段541a、541b。FIG. 7A is a partial perspective view of the supporting assembly 510 in FIG. 6B , and FIG. 7B is a perspective view of folding the foldable display device 500 in FIG. 5A . 7A and 7B, different from the aforementioned second pivot member 140, the second pivot member 540 further includes a pair of pivot parts 541 (on opposite sides of the support assembly 510, see FIG. 6B) and two The rotating shaft 542, and the support plate 543 is disposed between the pair of pivoting portions 541, and each pivoting portion 541 includes two connecting sections 541a, 541b.

各個樞轉部541的這些連接段541a、541b彼此旋轉連接，並分別連接第二主體512與第三主體513。在支撐組件510(見圖6B)的相對兩側的轉軸542彼此同軸且相對地設置。每根轉軸542連接並貫穿其中一個樞轉部541，所以每個樞轉部541的這些連接段541a、541b能沿著轉軸542而彼此相對旋轉。因此，第二主體512與第三主體513能沿著第二軸心A54而彼此相對旋轉。在本實施方式中，第二主體512與第三主體513為單軸樞轉設計。此外，支撐板543具有另外兩根轉軸，其連接這些連接段541a與541b。The connection sections 541 a , 541 b of each pivoting portion 541 are rotatably connected to each other, and are respectively connected to the second body 512 and the third body 513 . The rotation shafts 542 on opposite sides of the support assembly 510 (see FIG. 6B ) are coaxially and oppositely disposed to each other. Each rotating shaft 542 is connected to and passes through one of the pivoting portions 541 , so the connecting sections 541 a , 541 b of each pivoting portion 541 can rotate relative to each other along the rotating shaft 542 . Therefore, the second body 512 and the third body 513 can rotate relative to each other along the second axis A54. In this embodiment, the second body 512 and the third body 513 are designed to pivot on a single axis. In addition, the support plate 543 has two other rotating shafts, which connect the connecting sections 541a and 541b.

須說明的是圖7A描繪支撐組件510其一側在第一樞轉構件530與第二樞轉構件540處的部分內部，以使圖7A顯示僅一個轉軸542與一個樞轉部541，而其他轉軸542與其他樞轉部541未繪示於圖7A。如圖7A與圖7B所示，第一樞轉構件530包括多根轉軸532。當摺疊攤平的摺疊式顯示裝置500，但此時的第二主體512與第三主體513仍可保持攤平時（如圖7B所示），第一主體511與第二主體512透過第一樞轉構件530能沿著這些轉軸532而彼此相對旋轉。It should be noted that FIG. 7A depicts one side of the support assembly 510 at the first pivot member 530 and the second pivot member 540, so that FIG. 7A shows only one shaft 542 and one pivot portion 541, while the other The rotating shaft 542 and other pivoting parts 541 are not shown in FIG. 7A . As shown in FIGS. 7A and 7B , the first pivot member 530 includes a plurality of rotating shafts 532 . When the foldable display device 500 is folded flat, but the second body 512 and the third body 513 can still be kept flat (as shown in FIG. 7B ), the first body 511 and the second body 512 pass through the first hinge. The rotating members 530 can rotate relative to each other along these rotating shafts 532 .

圖7C是圖7B中處於第一狀態下的被摺疊的支撐組件510的側視示意圖，其中圖7C僅描繪第一狀態下被摺疊的支撐組件510的內部。請參閱圖7C，摺疊式顯示裝置500與支撐組件510能透過第一樞轉構件530與第二樞轉構件540在第二狀態與第一狀態之間切換。在第一狀態下，第一主體511與第三主體513彼此相對設置。相似於前述支撐組件110，摺疊的支撐組件510也具有P形側邊，如圖7C所示。因此，摺疊的支撐組件510也能避免破壞柔性顯示面板190，並滿足行動裝置方便攜帶的設計。FIG. 7C is a schematic side view of the folded support assembly 510 in the first state in FIG. 7B , wherein FIG. 7C only depicts the inside of the folded support assembly 510 in the first state. Please refer to FIG. 7C , the foldable display device 500 and the supporting assembly 510 can switch between the second state and the first state through the first pivoting member 530 and the second pivoting member 540 . In the first state, the first body 511 and the third body 513 are disposed opposite to each other. Similar to the aforementioned support assembly 110, the folded support assembly 510 also has P-shaped sides, as shown in FIG. 7C. Therefore, the folded support assembly 510 can also avoid damage to the flexible display panel 190 and satisfy the portable design of the mobile device.

圖7D是處於第一狀態下的柔性顯示面板190的示意圖，例如圖7C省略支撐組件510時的柔性顯示面板190。同時參閱圖7C與圖7D，當圖7C的支撐組件510處於第一狀態時，柔性顯示面板190在第三主體513的部分與在第二主體512的部分之間形成的第三夾角θ3在145度至165度的範圍中(例如154度)，而柔性顯示面板190在第一主體511與第二主體512任一者上的部分與水平線L之間形成的第四夾角θ4在95度至115度的範圍中(例如103度)。FIG. 7D is a schematic diagram of the flexible display panel 190 in the first state, for example, the flexible display panel 190 when the support assembly 510 is omitted in FIG. 7C . Referring to FIG. 7C and FIG. 7D at the same time, when the support assembly 510 in FIG. 7C is in the first state, the third angle θ3 formed between the part of the third body 513 and the part of the second body 512 of the flexible display panel 190 is at 145 degrees to 165 degrees (for example, 154 degrees), and the fourth angle θ4 formed between the part of the flexible display panel 190 on any one of the first body 511 and the second body 512 and the horizontal line L is in the range of 95 degrees to 115 degrees. degrees (e.g. 103 degrees).

圖8是摺疊圖7A中的支撐組件510在第二樞轉構件540處的局部立體示意圖。請參閱圖7A與圖8，第二樞轉構件540可以更包括至少一個導引件545。在圖8的較佳實施例中，第二樞轉構件540包括兩個導引件545，其中支撐板543連接並位於導引件545之間。在其他較佳實施例中，第二樞轉構件540可以包括單一個導引件545，所以第二樞轉構件540所包括的導引件545之數量不限制是兩個。FIG. 8 is a partial perspective view of the support assembly 510 in FIG. 7A folded at the second pivot member 540 . Please refer to FIG. 7A and FIG. 8 , the second pivoting member 540 may further include at least one guiding part 545 . In the preferred embodiment of FIG. 8 , the second pivot member 540 includes two guides 545 , wherein a support plate 543 is connected and located between the guides 545 . In other preferred embodiments, the second pivot member 540 may include a single guide piece 545 , so the number of guide pieces 545 included in the second pivot member 540 is not limited to two.

同一個樞轉部541的這些連接段541a、541b能可旋轉地連接其中一個導引件545，以使每個連接段541a、541b能相對於導引件545而旋轉。在較佳實施例中，每個導引件545具有插槽S42，其中所有插槽S42沿著遠離支撐板543的方向延伸。轉軸542與插槽S42分別對準，以使每根轉軸542能***其中一個插槽S42內。These connection sections 541 a , 541 b of the same pivot part 541 can be rotatably connected to one of the guides 545 , so that each connection section 541 a , 541 b can rotate relative to the guide 545 . In a preferred embodiment, each guide piece 545 has a slot S42 , wherein all the slots S42 extend away from the support plate 543 . The rotating shafts 542 are respectively aligned with the slots S42 so that each rotating shaft 542 can be inserted into one of the slots S42.

當摺疊式顯示裝置500處於第二狀態，即摺疊式顯示裝置500被攤平時，這些轉軸542能***於這些插槽S42內。同時，導引件545能限制這些轉軸542移動，以防止摺疊式顯示裝置500突然間的摺疊。相反地，當摺疊式顯示裝置500處於第一狀態，即摺疊式顯示裝置500被摺疊時，轉軸542能離開插槽S42。When the foldable display device 500 is in the second state, that is, when the foldable display device 500 is flattened, the rotating shafts 542 can be inserted into the slots S42.
