轉軸結構(一) Rotating shaft structure (I)

本創作係有關於一種鉸鏈，尤指一種折疊式電子裝置之轉軸結構。 This work is about a hinge, especially a hinge structure of a foldable electronic device.

在現有“折疊式裝置”中，會依內折或外折後以及彎曲部的曲率，需要搭配不同的轉軸結構設計，以避免妨礙屏幕的折疊動作而造成拉扯。屏幕內折的折疊式裝置在開合動作上，主要是沿襲傳統的折疊式裝置，在折疊後能將屏幕保護於內部，且比較接近使用者習慣而易於被接受，然而在此類產品中，其轉軸結構的結構設計會受限於所採用的屏幕類型，亦須考量屏幕內折後的彎曲部會呈現水滴形或是馬蹄形或是雙硬屏摺叠結構的其中的一樣態，而形成差異性。其中，其所需考量的組成構件及彼此間的連接關係和動作，都是影響屏幕是否容易損傷及使用壽命的關鍵因素。 In existing "folding devices", different hinge structure designs are required depending on whether the device folds inward or outward and the curvature of the curved part to avoid hindering the folding action of the screen and causing pulling. The opening and closing actions of folding devices with inward folding screens mainly follow the traditional folding devices. After folding, the screen can be protected inside, and it is closer to user habits and easier to accept. However, in such products, the structural design of the hinge structure is limited by the type of screen used, and it is also necessary to consider whether the curved part of the screen after folding inward will present a water drop shape, a horseshoe shape, or a double hard screen folding structure, which creates differences. Among them, the components that need to be considered and the connection relationships and actions between them are all key factors that affect whether the screen is easy to be damaged and its service life.

針對上述轉軸結構，如CN110630625B、CN109469680B、CN109654113B與CN209959699U各個專利所示，主要是嘗試各種結構設計，以兼具薄型化及整體美觀的效果。而在現有的製造工藝及成本的考量下，欲達到薄型化的效果，轉軸結構在折疊時，通過虛擬旋轉中心提供位移補償所產生的效果較佳，例如CN219345251U號之「柔屏轉軸結構」專利案所示，其主要是在底座的兩個弧形部分別樞接兩個轉軸模組，任一轉軸模組的一殼體連杆的兩端分別具有一凸出部及一限位部；一連接板位於凸出部的頂端並樞接殼體連杆，連接板通過一拉伸彈簧以連接殼體連杆，或是通過至少一彎折片以對應抵接一弧形擺臂的至少一限位板；弧形擺臂具有連接弧形部的一導引部，弧形擺臂樞接殼體連杆的凸出部；一齒輪連杆的一端連接至少一軸杆，齒輪連杆另一端的滑動部與限位部同軸套接一導柱。For the above-mentioned rotating shaft structure, as shown in the patents CN110630625B, CN109469680B, CN109654113B and CN209959699U, various structural designs are mainly tried to achieve both thinness and overall aesthetics. However, under the consideration of existing manufacturing processes and costs, in order to achieve the effect of thinness, the rotating shaft structure provides displacement compensation through the virtual rotation center when folded, which is better. For example, as shown in the patent case of "Flexible Screen Rotating Shaft Structure" No. CN219345251U, it is mainly to connect two rotating shaft modules at two arc-shaped parts of the base, and the two ends of a shell connecting rod of any rotating shaft module have a protrusion and a limit respectively. A connecting plate is located at the top end of the protruding portion and is pivotally connected to the shell connecting rod, the connecting plate is connected to the shell connecting rod through a tension spring, or through at least one bent sheet to correspond to at least one limiting plate of an arc-shaped swing arm; the arc-shaped swing arm has a guide portion connected to the arc-shaped portion, and the arc-shaped swing arm is pivotally connected to the protruding portion of the shell connecting rod; one end of a gear connecting rod is connected to at least one shaft, and the sliding portion at the other end of the gear connecting rod is coaxially sleeved with a guide column with the limiting portion.

惟，CN219345251U一案主要是經由兩個導引部分別連接底座之兩個弧形部，藉以讓兩個弧形擺臂分別在底座上相對弧形擺動。在實際生產時，「弧形導引部」及「弧形部」之搭配方式，不但在分開製造上較為困難而會增加生產成本，且在組合時容易會由於製造公差，會有鬆動不穩定或是不順暢之問題產生。However, the CN219345251U case mainly connects the two arc-shaped parts of the base through two guide parts, so that the two arc-shaped swing arms can swing in an arc shape relative to each other on the base. In actual production, the combination of the "arc-shaped guide part" and the "arc-shaped part" is not only difficult to manufacture separately, which will increase the production cost, but also easy to cause looseness, instability or unsmoothness due to manufacturing tolerance when combined.

有鑑於此，為了提供一種有別於習用技術之結構，並改善上述之缺點，創作人積多年的經驗及不斷的研發改進，遂有本創作之產生。In view of this, in order to provide a structure that is different from the commonly used technology and improve the above-mentioned shortcomings, the creators have accumulated many years of experience and continuous research and development and improvement, thus producing this creation.

The invention can use the first arc tooth part of the base to gear the first tooth row of the first rotating member, and through the base, the first shaft, the first The four-link structure composed of the first rotating member, the second rotating member and the third rotating member is convenient for manufacturing and assembly, thereby reducing production costs, and helps to reduce the overall thickness, making the overall thinner.

In this way, when the third rotating rod 43 and the first rotating rod 41 rotate at the same time, and the second rotating rod 42 and the third rotating rod 43 move relatively at the same time, a receiving space 94 can be released at the intersection of the first shell 91 and the second shell 92 to accommodate the curved part in the middle of the screen 93.

在本實施例中，同動組件5包括依序相鄰齒合之一第一齒輪53、一中間齒輪組54及一第二齒輪55；支撐座51包括間隔並列之兩個長形板片，同動組件5夾置於兩個長形板片之間，藉以讓支撐座51定位同動組件5；而第一轉軸343及第二轉軸432依序穿過支撐座51之兩端、同動組件5之第一齒輪53與第二齒輪55，以及第一定位件52之兩端，並分別以一第一端封件56與一第二端封件57鎖接第一轉軸343及第二轉軸432之端部上，即可固定壓縮第一定位件52，並讓第一轉軸343及第二轉軸432反向轉動，進而讓相對彎折之屏幕93兩半部在翻轉至閉合或完全展開的過程中，能夠穩定的轉動及定位在預設角度，並在轉動時自由停滯在一定的角度上。In this embodiment, the synchronous assembly 5 includes a first gear 53, an intermediate gear set 54 and a second gear 55 which are adjacent to each other in sequence; the support base 51 includes two elongated plates which are spaced and arranged side by side, and the synchronous assembly 5 is sandwiched between the two elongated plates so that the support base 51 can position the synchronous assembly 5; and the first rotating shaft 343 and the second rotating shaft 432 pass through the two ends of the support base 51, the first gear 53 and the second gear 55 of the synchronous assembly 5, and the first rotating shaft 432 in sequence. The two ends of the positioning member 52 are respectively locked to the ends of the first rotating shaft 343 and the second rotating shaft 432 by a first end seal 56 and a second end seal 57, so that the first positioning member 52 can be fixed and compressed, and the first rotating shaft 343 and the second rotating shaft 432 can be rotated in opposite directions, so that the two halves of the relatively bent screen 93 can be stably rotated and positioned at a preset angle during the process of flipping to close or fully unfolding, and can freely stop at a certain angle during rotation.

藉此，當第一殼體91與第二殼體92呈現在展平狀態時，經由第一連動機構3及第二連動機構4之兩個彈性件(336,336’)分別拉動兩個擺動件(33,33’) 、以及經由第一側板21和第二側板22之一端分別抵接兩個支撐板(95,95’)之中部板面，即可讓中板26、兩個平面部(345,433)以及兩個支撐板(95,95’)共同支撐屏幕93，以產生全面性且穩定之支撐力量；此時，兩個彈性件(336,336’)分別為被拉伸以蓄積彈力，並降低因製造公差的間隙影響。Thus, when the first shell 91 and the second shell 92 are in a flattened state, the two elastic members (336, 336') of the first linkage mechanism 3 and the second linkage mechanism 4 respectively pull the two swing members (33, 33'), and one end of the first side plate 21 and the second side plate 22 respectively abuts against the middle plate surfaces of the two support plates (95, 95'), so that the middle plate 26, the two plane portions (345, 433) and the two support plates (95, 95') can jointly support the screen 93 to generate a comprehensive and stable supporting force; at this time, the two elastic members (336, 336') are respectively stretched to accumulate elastic force and reduce the gap effect due to manufacturing tolerance.

而如圖3及圖10~13所示，當第一殼體91與第二殼體92相對翻轉時，經由座體2、第一轉軸343、第一轉動件31、第二轉動件32、第三轉動件34所組成之一組類似四連桿結構，以及座體2、第二轉軸432、第一轉動桿41、第二轉動桿42、第三轉動桿43所組成之另一組類似四連桿結構，再經由二個彈性件(336,336’)之彈力回復作用，使兩個擺動件(33,33’)產生類似蹺蹺板的作用，同時兩個擺動件(33,33’)之兩個定位部(334,334’)分別被兩個限位部(314,314’) 之一側邊推抵至兩個限位部(314,314’)之底端，使兩個轉接板(331,331’)及兩個支撐板(95,95’)相對偏移一角度，再形成容置空間94以容納屏幕93之彎曲狀中間部位。As shown in FIG. 3 and FIG. 10 to FIG. 13, when the first housing 91 and the second housing 92 are turned over relative to each other, a four-link structure is formed by the base 2, the first shaft 343, the first rotating member 31, the second rotating member 32, and the third rotating member 34, and the base 2, the second shaft 432, the first rotating rod 41, the second rotating rod 42, and the third rotating member 34. Another set of four-link structure formed by the movable rod 43, through the elastic restoring action of the two elastic members (336, 336'), the two swinging members (33, 33') produce a seesaw-like action, and at the same time, the two positioning parts (334, 334') of the two swinging members (33, 33') are pushed to the bottom ends of the two limiting parts (314, 314') by one side of the two limiting parts (314, 314'), so that the two adapter plates (331, 331') and the two supporting plates (95, 95') are relatively offset by an angle, and then the accommodating space 94 is formed to accommodate the curved middle part of the screen 93.

此外，更可選擇如圖2及圖14~17所示，當第一殼體91與第二殼體92由閉合狀態至展平時，由於兩個支撐板(95,95’)中部之一端分別滑動連接第一長形導槽291及第二長形導槽292，其中可視情況進一步在這兩個長形導槽內形成弧曲面(或是可變曲率弧面)，以供兩個支撐板(95,95’)中部之一端沿著滑動，兩個支撐板(95,95’)的板面在展平過程中，各自始終滑動抵接第一側板21和第二側板22之一端，進而使兩個擺動件(33,33’)分別相對第二轉動件32及第二轉動桿42旋轉，當兩個弧形導引部333之内側一端分別接觸兩個弧形部321之後，將分別拉動第二轉動件32及第二轉動桿42向座體2方向移動，以補償轉軸結構1在展開時的位移差。而兩個限位部(314,314’)之另一側邊在展平過程中分別滑動抵接兩個定位部(334,334’)，反向推抵兩個擺動件(33,33’)以分別拉動第二轉動件32及第二轉動桿42向座體2方向移動，則可以同步補償位移差。In addition, as shown in FIG. 2 and FIG. 14 to FIG. 17, when the first shell 91 and the second shell 92 are flattened from the closed state, one end of the middle portion of the two support plates (95, 95') is slidably connected to the first elongated guide groove 291 and the second elongated guide groove 292, respectively, wherein a curved surface (or a curved surface with a variable curvature) can be further formed in the two elongated guide grooves according to the situation, so that one end of the middle portion of the two support plates (95, 95') can slide along the two support plates (9 During the flattening process, the plate surfaces (5,95') of the first side plate 21 and the second side plate 22 are always slidably abutted against one end of the first side plate 21 and the second side plate 22, thereby causing the two swinging members (33, 33') to rotate relative to the second rotating member 32 and the second rotating rod 42 respectively. When the inner ends of the two arc-shaped guide portions 333 contact the two arc-shaped portions 321 respectively, the second rotating member 32 and the second rotating rod 42 are pulled toward the seat body 2 respectively to compensate for the displacement difference of the shaft structure 1 when it is unfolded. The other side edges of the two limit portions (314, 314') slide against the two positioning portions (334, 334') during the flattening process, and push the two swinging members (33, 33') in the opposite direction to pull the second rotating member 32 and the second rotating rod 42 to move toward the seat body 2, thereby synchronously compensating for the displacement difference.

另如圖18、圖19所示，上述同動組件5、支撐座51及第一定位件52之組合亦可以另一組結構取代，而所取代之結構主要包括一長形連動板6、一長形限位板61、一第三齒形件62以及一第四齒形件63，其中之長形連動板6的一側面上抵壓四個並列之第二定位件64；長形限位板61平行設置於長形連動板6之另一側；第一轉軸343同軸設置一第一齒形件65，第一轉軸343之兩端分別以轉動之方式定位於長形連動板6及長形限位板61上；第二轉軸432同軸設置一第二齒形件66，第二轉軸432之兩端分別以轉動之方式定位於長形連動板6與長形限位板61上；第三齒形件62之一端定位於長形連動板6之另一側面上，且第三齒形件62以相對移動之方式齒接第一齒形件65；第四齒形件63平行第三齒形件62，第四齒形件63之一端定位於長形連動板6之另一側面上，且第四齒形件63以相對移動之方式齒接第二齒形件66，藉以在第一轉軸343及第二轉軸432相對反向轉動時，能讓第三齒形件62、第四齒形件63及長形連動板6同步移動，並以長形連動板6推壓四個第二定位件64，同樣可以讓相對彎折之屏幕93兩半部在翻轉至閉合或完全展開的過程中，能夠穩定的轉動及定位在預設角度，並在轉動時自由停滯在一定的角度上。As shown in FIGS. 18 and 19, the combination of the above-mentioned synchronous assembly 5, the support seat 51 and the first positioning member 52 can also be replaced by another structure, and the replaced structure mainly includes an elongated linkage plate 6, an elongated stop plate 61, a third tooth-shaped member 62 and a fourth tooth-shaped member 63, wherein one side surface of the elongated linkage plate 6 presses against four parallel second positioning members 64; the elongated stop plate 61 The first rotating shaft 343 is coaxially provided with a first toothed member 65, and the two ends of the first rotating shaft 343 are respectively positioned on the elongated connecting plate 6 and the elongated limiting plate 61 by means of rotation; the second rotating shaft 432 is coaxially provided with a second toothed member 66, and the two ends of the second rotating shaft 432 are respectively positioned on the elongated connecting plate 6 and the elongated limiting plate 61 by means of rotation; One end of the three-toothed member 62 is positioned on the other side of the long connecting plate 6, and the third toothed member 62 is engaged with the first toothed member 65 in a relatively movable manner; the fourth toothed member 63 is parallel to the third toothed member 62, and one end of the fourth toothed member 63 is positioned on the other side of the long connecting plate 6, and the fourth toothed member 63 is engaged with the second toothed member 66 in a relatively movable manner, so as to rotate the first shaft 343 When the second rotating shaft 432 rotates in the opposite direction, the third tooth member 62, the fourth tooth member 63 and the long connecting plate 6 can move synchronously, and the long connecting plate 6 pushes the four second positioning members 64. Similarly, the two halves of the relatively bent screen 93 can be stably rotated and positioned at a preset angle during the process of flipping to close or fully unfolding, and can freely stop at a certain angle during rotation.

綜上所述，依上文所揭示之內容，本創作係在座體之兩側反向設置一第一弧形齒部及一第二弧形齒部，第一轉動件的第一齒排齒接第一弧形齒部，第一轉動桿的第二齒排齒接第二弧形齒部，即可讓第一殼體與第二殼體能穩定的反向轉動，取代傳統轉軸結構中的提供位移補償的弧形擺臂，有助於縮減整體厚度，使整體更具薄型化效果。而經由第一轉軸、第一轉動件、第二轉動件、第三轉動件組成一組類似四連桿結構，以及座體、第二轉軸、第一轉動桿、第二轉動桿、第三轉動桿共同組成另一組類似四連桿結構，則可在第一殼體與第二殼體對合時，以第三轉動件/第三轉動桿與第一轉動件/第一轉動桿分別滑動連接兩個定位板，在位移及轉動時形成行程路徑與長度的補償轉換，以補償柔性屏或雙硬屏摺叠結構之彎折部位所形成的曲率半徑與兩殼體間的曲率半徑之間的尺寸差異，同時牽引帶動兩個轉接板以提供讓位空間，使柔性屏摺叠收攏；在屏幕展平時，能經由兩個彈性件之分別拉動使兩個轉接板復位，對屏幕形成穩定之支撐，又能在摺疊過程中降低空轉行程的影響。In summary, according to the contents disclosed above, the invention sets a first arc-shaped tooth portion and a second arc-shaped tooth portion in opposite directions on both sides of the base body, the first tooth row of the first rotating member is connected to the first arc-shaped tooth portion, and the second tooth row of the first rotating rod is connected to the second arc-shaped tooth portion, so that the first shell and the second shell can stably rotate in opposite directions, replacing the arc-shaped swing arm that provides displacement compensation in the traditional shaft structure, which helps to reduce the overall thickness and make the overall thinner. The first rotating shaft, the first rotating member, the second rotating member, and the third rotating member form a four-link structure, and the seat, the second rotating shaft, the first rotating rod, the second rotating rod, and the third rotating rod form another four-link structure. When the first housing and the second housing are matched, the third rotating member/the third rotating rod and the first rotating member/the first rotating rod are respectively slidably connected to the two positioning plates to form a stroke during displacement and rotation. The path and length are converted for compensation to compensate for the size difference between the curvature radius formed by the bending part of the flexible screen or the double rigid screen folding structure and the curvature radius between the two shells, and at the same time, the two adapter plates are pulled to provide clearance space so that the flexible screen can be folded and retracted; when the screen is flattened, the two adapter plates can be pulled back to their original positions by the two elastic parts respectively, so as to form a stable support for the screen and reduce the impact of the idling stroke during the folding process.
