在現有折疊式電子裝置中，第一機體與第二機體往往是通過鉸鏈模組樞接彼此，且可撓式螢幕的可彎折區通常是對應且位於至少一鉸鏈模組上。因此，當第一機體與第二機體相對展開時，鉸鏈模組應配合其他元件使可撓式螢幕保持平整的狀態，而當第一機體與第二機體相對收折、閉合時，鉸鏈模組則應配合其他元件提供讓位空間，以供可撓式螢幕容置，避免可彎折區受到折損。 In existing foldable electronic devices, the first body and the second body are often hinged to each other through a hinge module, and the bendable area of the flexible screen is usually corresponding and located on at least one hinge module. Therefore, when the first body and the second body are unfolded relative to each other, the hinge module should cooperate with other components to keep the flexible screen flat, and when the first body and the second body are folded and closed relative to each other, the hinge module should cooperate with other components to provide space for the flexible screen to accommodate and prevent the bendable area from being damaged.

然而，為了提供可撓式螢幕足夠的容置空間，當第一機體與第二機體相對翻轉的過程中，位於至少一鉸鏈模組上的可彎折區會有懸浮現象，從而影響使用者操作。 However, in order to provide sufficient accommodation space for the flexible screen, when the first body and the second body are flipped relative to each other, the bendable area on at least one hinge module will be suspended, thereby affecting the user's operation.

In this embodiment, in the hinge module 100, a pair of gear shafts 160 of a pair of movable support plate structures 105 are engaged and rotate around the second axis AX2 (parallel to the X axis) respectively (the second axis AX2 is an invisible virtual axis), and the first axis AX1 (parallel to the X axis) and the corresponding second axis AX2 (parallel to the X axis) in each movable support plate structure 105 are misaligned in the Z axis direction (FIG. 3A, FIG. 5A to FIG. 5C).

在此，需說明的是，每一個弧形軸部102會有其所對應旋轉的第一軸線AX1。在本實施例中，一對活動支撐板結構105中的第一軸線AX1例如相重合，因此本實施例的圖面是繪示一個第一軸線AX1，但不以此為限。請參考圖7，在另一實施例中，一對活動支撐板結構105A中的一對第一軸線AX1例如是相平行且 呈對稱設置，因此圖7是繪示兩個第一軸線AX1，但不以此為限制。在其他實施例中，一對活動支撐板結構(未示出)中的一對第一軸線(未示出)相平行且並沒有呈對稱設置，從而透過旋轉件(未示出)的不同的第二滑槽(未示出)的輪廓所控制，達到一對活動支撐板結構(未示出)依然能夠同步旋轉的作用。 Here, it should be noted that each arc-shaped axis 102 has a corresponding first axis AX1 for rotation. In this embodiment, the first axes AX1 in a pair of movable support plate structures 105 are, for example, overlapped, so the figure of this embodiment shows one first axis AX1, but it is not limited to this. Please refer to FIG. 7, in another embodiment, a pair of first axes AX1 in a pair of movable support plate structures 105A are, for example, parallel and symmetrically arranged, so FIG. 7 shows two first axes AX1, but it is not limited to this.

此處，需說明的是，請參考圖6A，在本實施例中，固定座230設置於外殼103中，且第一轉動支架210的第一滑動部211及第二轉動支架220的第二滑動部221位在外殼103與固定座230之間。請參考圖2，在本實施例中，在本實施例中，第一滑動部211的第三軸線AX3與第二轉動支架220的第三軸線AX3例如是與第一軸線AX1重合，但不以此為限。在其他實施例中，第一滑動部211的第三軸線AX3例如平行於第二轉動支架220的第三軸線AX3。 Here, it should be noted that, please refer to FIG. 6A , in this embodiment, the fixing seat 230 is disposed in the outer shell 103, and the first sliding portion 211 of the first rotating bracket 210 and the second sliding portion 221 of the second rotating bracket 220 are located between the outer shell 103 and the fixing seat 230. Please refer to FIG. 2 , in this embodiment, in this embodiment, the third axis AX3 of the first sliding portion 211 and the third axis AX3 of the second rotating bracket 220 are, for example, coincident with the first axis AX1, but not limited thereto. In other embodiments, the third axis AX3 of the first sliding portion 211 is, for example, parallel to the third axis AX3 of the second rotating bracket 220.

更具體而言，請參考圖6A及圖6B，在本實施例中，第一連接支架240包括相連接的第一桿體241及第一座部242，且第二連接支架250包括相連接的第二桿體251及第二座部252。第一桿體241樞設於第一中間部212，以使第一連接支架240平行X軸相對於第一轉動支架210旋轉。第二桿體251樞設於第二中間部222，以使第二連接支架250平行X軸相對於第二轉動支架220旋轉。 More specifically, please refer to FIG. 6A and FIG. 6B.

In this embodiment, the first fixing portion 213 and the second fixing portion 223 are respectively connected to a pair of first supporting plates 110, and the first seat portion 242 and the second seat portion 252 are respectively connected to a pair of second supporting plates 120. In this way, the setting of the limit module 200 can assist the rotation of each second supporting plate 120 relative to the corresponding first supporting plate 110, thereby improving the structural stability of the hinge module 100 during rotation.

以下進一步說明鉸鏈模組100的作動方式。 The operation of the hinge module 100 is further described below.

請參考圖4A至圖5C，在本實施例中，由於第一軸線AX1(平行X軸)與第二軸線AX2(平行X軸)相錯位，使得旋轉承架130與控制承架150的旋轉軸心不同，因此當一對活動支撐板結構105相對旋轉而在閉合模式M1(圖4A、圖5A)、中間模式MC(圖4B、圖5B)及展開模式M2(圖4C、圖5C)之間轉換時，控制承架150的第一端部151將錯位滑動於旋轉承架130的第一滑槽SL1中(圖5A至圖5C)，並同時使控制承架150的第二端部152沿第二滑槽SL2滑動(圖5A至圖5C)，從而連動旋轉件140相對於旋轉承架130旋轉，讓與旋轉件140連接的第二支撐板120相對於與旋轉承架130連接的第一支撐板110旋轉。 4A to 5C, in this embodiment, since the first axis AX1 (parallel to the X axis) and the second axis AX2 (parallel to the X axis) are misaligned, the rotation axes of the rotating support frame 130 and the control support frame 150 are different. Therefore, when the pair of movable support plate structures 105 rotate relative to each other and switch between the closed mode M1 (FIG. 4A, FIG. 5A), the intermediate mode MC (FIG. 4B, FIG. 5B) and the expanded mode M2 (FIG. 4C, FIG. 5C), the control The first end 151 of the support frame 150 will slide misaligned in the first slide slot SL1 of the rotating support frame 130 (Figure 5A to Figure 5C), and at the same time, the second end 152 of the control support frame 150 will slide along the second slide slot SL2 (Figure 5A to Figure 5C), thereby linking the rotating member 140 to rotate relative to the rotating support frame 130, and allowing the second support plate 120 connected to the rotating member 140 to rotate relative to the first support plate 110 connected to the rotating support frame 130.

具體而言，如圖5A所示，在本實施例中，當一對所述活動支撐板結構105之間的旋轉角度是0度而為閉合模式M1時，每一個控制承架150的第一端部151將錯位滑動至第一滑槽SL1的第一位置P11，且每一個控制承架150的第二端部152受到帶動而滑動至第二滑槽SL2的第一位置P21。 Specifically, as shown in FIG. 5A , in this embodiment, when the rotation angle between the pair of movable support plate structures 105 is 0 degrees and the closed mode M1 is reached, the first end 151 of each control bracket 150 will slide misaligned to the first position P11 of the first slide slot SL1, and the second end 152 of each control bracket 150 will be driven to slide to the first position P21 of the second slide slot SL2.

此時，如圖4A及圖5A所示，透過第二端部152(圖5A)的滑動帶動旋轉件140相對於旋轉承架130旋轉，使每一個第二支撐板120相對於對應的第一支撐板110旋轉而形成讓位空間AC，同時由於一對第一支撐板110相平行(平行Z軸)及藉由外殼103的設置，讓可撓螢幕55(圖4A)呈水滴型並與外殼103適應性地切 齊。 At this time, as shown in FIG. 4A and FIG. 5A, the second end 152 (FIG. 5A) slides to drive the rotating member 140 to rotate relative to the rotating support frame 130, so that each second support plate 120 rotates relative to the corresponding first support plate 110 to form a clearance space AC. At the same time, due to the parallelism of a pair of first support plates 110 (parallel to the Z axis) and the setting of the outer shell 103, the flexible screen 55 (FIG. 4A) is in a teardrop shape and is adaptively cut with the outer shell 103.

如此，可透過第二支撐板120相對於第一支撐板110的旋轉，增加可撓螢幕55(圖4A)的容置空間，且能夠避免習知可撓螢幕在收折時因與鉸鏈模組之間的間隙過大，所造成的懸浮現象及影響使用者操作的問題。 In this way, the second support plate 120 can be rotated relative to the first support plate 110 to increase the accommodation space of the retractable screen 55 (FIG. 4A), and the problem of the retractable screen being suspended and affecting the user's operation due to the large gap between the retractable screen and the hinge module when folded can be avoided.

如圖5B所示，在本實施例中，當一對所述活動支撐板結構105之間的旋轉角度是90度而為中間模式MC時，每一個控制承架150的第一端部151將錯位滑動至第一滑槽SL1的中間位置P13，且每一個控制承架150的第二端部152受到帶動而滑動至第二滑槽SL2的中間位置P23。 As shown in FIG. 5B , in this embodiment, when the rotation angle between the pair of movable support plate structures 105 is 90 degrees and the middle mode MC is reached, the first end 151 of each control bracket 150 will slide misaligned to the middle position P13 of the first slide slot SL1, and the second end 152 of each control bracket 150 will be driven to slide to the middle position P23 of the second slide slot SL2.

此時，如圖4B及圖5B所示，透過第二端部152(圖5B)的滑動帶動旋轉件140相對於旋轉承架130旋轉，使每一個第二支撐板120相對於對應的第一支撐板110旋轉，從而讓第二支撐板120能夠在不同旋轉角度下皆能夠給予可撓螢幕55(圖4B)支撐，避免可撓螢幕55(圖4B)於收折及展開的過程中懸浮，影響使用者操作。 At this time, as shown in FIG. 4B and FIG. 5B , the second end 152 ( FIG. 5B ) slides to drive the rotating member 140 to rotate relative to the rotating support frame 130 , so that each second support plate 120 rotates relative to the corresponding first support plate 110 , so that the second support plate 120 can support the flexible screen 55 ( FIG. 4B ) at different rotation angles, and prevent the flexible screen 55 ( FIG. 4B ) from floating during the folding and unfolding process, which affects the user's operation.

如圖5C所示，在本實施例中，當一對活動支撐板結構105之間的旋轉角度是180度而為展開模式M2時，每一個控制承架150的第一端部151將錯位滑動至第一滑槽SL1的第二位置P12，且每一個控制承架150的第二端部152受到帶動而滑動至第二滑槽SL2的第二位置P22。 As shown in FIG. 5C , in this embodiment, when the rotation angle between a pair of movable support plate structures 105 is 180 degrees and in the deployment mode M2, the first end 151 of each control bracket 150 will slide misaligned to the second position P12 of the first slide slot SL1, and the second end 152 of each control bracket 150 will be driven to slide to the second position P22 of the second slide slot SL2.

此時，如圖4C及圖5C所示，透過第二端部152(圖5C) 的滑動帶動旋轉件140相對於旋轉承架130旋轉，使每一個第二支撐板120相對於對應的第一支撐板110旋轉，讓每一個第一支撐板110的支撐面與每一個第二支撐板120的支撐面切齊，而可同步支撐可撓螢幕55(圖4C)，從而使可撓螢幕55(圖4C)攤開而呈平面狀。 At this time, as shown in FIG. 4C and FIG. 5C, the second end 152 (FIG. 5C) is slidably driven to rotate the rotating member 140 relative to the rotating support frame 130, so that each second support plate 120 rotates relative to the corresponding first support plate 110, so that the supporting surface of each first support plate 110 is aligned with the supporting surface of each second support plate 120, and the retractable screen 55 (FIG. 4C) can be supported synchronously, so that the retractable screen 55 (FIG. 4C) is spread out and becomes a plane.

如此一來，控制承架150相對於第一支撐板110與固定部131的滑動，可由第一軸線AX1及第二軸線AX2之間的錯位所觸發(即圖4A至圖5C中第一軸線AX1及第二軸線AX2在Z軸向上的距離大於0)，且第二支撐板120相對於第一支撐板110的旋轉角度，可由旋轉件140的第二滑槽SL2的輪廓所控制。 In this way, the sliding of the control support 150 relative to the first supporting plate 110 and the fixing portion 131 can be triggered by the misalignment between the first axis AX1 and the second axis AX2 (i.e., the distance between the first axis AX1 and the second axis AX2 in the Z-axis direction in FIGS. 4A to 5C is greater than 0), and the rotation angle of the second supporting plate 120 relative to the first supporting plate 110 can be controlled by the profile of the second slide slot SL2 of the rotating member 140.

也就是說，在本實施例中，當第一機體60及第二機體70相對於彼此的同步旋轉時，可利用旋轉承架130與控制承架150的旋轉軸心不同所造成的錯位滑動，以及透過控制承架150的第一端部151及第二端部152分別被第一滑槽SL1及第二滑槽SL2所限制，有效在翻轉過程中控制控制承架150的錯位滑動以及旋轉件140的旋轉，使與旋轉件140連接的第二支撐板120相對於第一支撐板110旋轉，而讓第二支撐板120在不同旋轉角度下皆能夠給予可撓螢幕55(圖4A至圖4C)支撐，避免可撓螢幕55產生懸浮現象，並可在不同模式下形成讓位空間AC(圖4A、圖5A)及切齊的支撐面(圖4C、圖5C)，從而具有較佳的操作性。 That is, in this embodiment, when the first body 60 and the second body 70 rotate synchronously relative to each other, the misaligned sliding caused by the different rotation axes of the rotating support frame 130 and the control support frame 150 can be utilized, and the first end 151 and the second end 152 of the control support frame 150 are respectively restricted by the first slide groove SL1 and the second slide groove SL2, so as to effectively control the misaligned sliding of the control support frame 150 and the rotation of the rotating member 130 during the flipping process. 40, the second support plate 120 connected to the rotating member 140 rotates relative to the first support plate 110, so that the second support plate 120 can support the flexible screen 55 (Figure 4A to Figure 4C) at different rotation angles, avoiding the flexible screen 55 from floating, and forming a clearance space AC (Figure 4A, Figure 5A) and a neat support surface (Figure 4C, Figure 5C) in different modes, thereby having better operability.

綜上所述，在本發明的電子裝置中，連接於第一機體及第二機體之間的鉸鏈模組，可利用旋轉承架的第一軸線與控制承架 的第二軸線之間的錯位，以及透過控制承架的第一端部及第二端部分別被第一滑槽及第二滑槽所限制，有效在第一機體及第二機體翻轉的過程中，控制控制承架的錯位滑動以及旋轉件的旋轉，使與旋轉件連接的第二支撐板相對於第一支撐板旋轉，而讓第二支撐板在不同旋轉角度下皆能夠給予可撓螢幕支撐，避免可撓螢幕產生懸浮現象，並可在不同模式下形成讓位空間及切齊的支撐面，從而具有較佳的操作性。 In summary, in the electronic device of the present invention, the hinge module connected between the first body and the second body can utilize the misalignment between the first axis of the rotating support and the second axis of the control support, and through the first end and the second end of the control support being respectively restricted by the first slide slot and the second slide slot, effectively control the misalignment sliding of the control support and the rotation of the rotating member during the flipping of the first body and the second body, so that the second support plate connected to the rotating member rotates relative to the first support plate, and the second support plate can provide support for the flexible screen at different rotation angles, avoiding the flexible screen from floating, and can form a space for making way and a neat support surface in different modes, thereby having better operability.
