Description

折疊式鉸鏈folding hinge

本案係有關一種鉸鏈，尤指一種適用於折疊式電子裝置的折疊式鉸鏈。This case relates to a hinge, especially a foldable hinge suitable for foldable electronic devices.

按現有折疊式電子裝置，例如折疊式手機，主要是通過對開式鉸鏈或是多軸式鉸鏈分別連接該折疊式電子裝置的一可撓性螢幕，例如OLED側邊的各支撐件以形成樞設，藉以使該可撓性螢幕能夠相對地翻轉掀開或閉合。According to the existing foldable electronic device, such as a foldable mobile phone, a flexible screen of the foldable electronic device, such as each support member on the side of the OLED, is mainly connected by a split hinge or a multi-axis hinge to form a pivot. , so that the flexible screen can be flipped open or closed relatively.

而由於現有的電子裝置主要是朝向薄型化的方向設計以便於攜帶，因此，在兩個機體之間能留給前述鉸鏈容置的間距即愈來愈窄，以致前述鉸鏈在厚度方面的尺寸要求也就勢必隨之縮減。Since the existing electronic devices are mainly designed to be thin and easy to carry, the space between the two bodies that can be reserved for the hinge accommodation becomes narrower and narrower, so that the size of the hinge is required in terms of thickness. It is bound to decrease accordingly.

因此，現有的折疊式電子裝置中，會依照該可撓性螢幕的內摺或外摺後，以及該可撓性螢幕的彎曲部之曲率來搭配不同的折疊式鉸鏈，以避免妨礙該可撓性螢幕的摺疊動作所造成的拉扯。Therefore, in the existing folding electronic device, different folding hinges are matched according to the inward or outward folding of the flexible screen and the curvature of the curved portion of the flexible screen, so as to avoid obstructing the flexible screen. The pull caused by the folding action of the sex screen.

其中，採用內摺式的該折疊式鉸鏈在開合動作上是沿襲傳統的折疊式電子裝置，並在摺疊後能將該可撓性螢幕保護於內部，且接近使用者的操作習慣而容易被接受，所以此類型產品近期推陳出新，相關業者陸續爭相開發。Among them, the folding hinge using the inward folding type follows the traditional folding electronic device in the opening and closing action, and after folding, the flexible screen can be protected inside, and it is close to the user's operating habits and is easy to be destroyed. Accepted, so this type of product has been introduced recently, and related industries have been scrambling to develop it.

然而在此類產品中，該折疊式鉸鏈的結構設計會受限於所採用該可撓性螢幕的結構類型，同時亦須考量該可撓性螢幕在內摺後之彎曲部會呈現「水滴狀」或「馬蹄形」的其中一種樣態，而形成差異性，尤其以適用於「水滴狀」的折疊式鉸鏈所需考量之組成構件及彼此間的連結關係和動作，都是會影響該可撓性螢幕是否容易損傷及使用壽命的關鍵因素。However, in this type of product, the structural design of the folding hinge is limited by the structure type of the flexible screen used, and it is also necessary to consider that the curved part of the flexible screen will appear "drop-shaped" after being folded inward. ” or “horseshoe-shaped”, and form a difference, especially for the “drop-shaped” folding hinge, the components and the connection relationship and movement between them that need to be considered will affect the flexibility. The key factor of whether the screen is easy to be damaged and its service life.

再者，由於前述折疊式鉸鏈所需組成構件較多，在製造及組裝上，更是極具挑戰的問題。Furthermore, since the aforementioned folding hinge requires many components, it is a very challenging problem in manufacturing and assembling.

目前折疊式鉸鏈在摺疊時形成虛擬旋轉中心為較佳的實施方案，特別是採用曲柄連桿機構比較能夠貼近該可撓性螢幕的內摺過程，但缺點是該曲柄連桿機構的元件繁多且更為細小，以致組裝時的角度就會比較特別，而使組裝要求較為嚴格且具有難度。At present, it is a better implementation for the foldable hinge to form a virtual center of rotation when folded. In particular, the use of a crank-link mechanism can be closer to the inward folding process of the flexible screen, but the disadvantage is that the crank-link mechanism has many components and Smaller, so that the angle during assembly will be special, and the assembly requirements will be stricter and more difficult.

另一方面，因為薄型化的設計，致使組成元件較為精細，由於各零件尺寸小且形狀複雜，無法採用傳統的鑄造或沖壓等工藝，因此各該零件大都採用金屬射出成型(Metal Injection Molding，縮寫為MIM)製造並加工後，體積多少會有縮減的情況，但只要在誤差值內(製造公差值)，都會被採用，因此該等零件組裝後，彼此之間多少會存在間隙，例如因應該虛擬旋轉中心所採用的弧形擺臂與本體之間的間隙過大，會在彼此作動的過程中，無法產生足夠摩擦力或是無摩擦力，此時稱為「空行程」，進而形成無效空轉或是明顯晃動情形，則會被視為不良品，容易造成良率過低而增加成本。On the other hand, due to the thin design, the components are relatively fine. Due to the small size and complex shape of each part, traditional casting or stamping processes cannot be used. Therefore, most of these parts adopt Metal Injection Molding (abbreviated as Metal Injection Molding). After manufacturing and processing for MIM), the volume will be reduced to some extent, but as long as it is within the error value (manufacturing tolerance value), it will be used, so after these parts are assembled, there will be some gap between each other, for example, due to The gap between the arc-shaped swing arm and the main body used for the virtual rotation center is too large, so that sufficient friction or no friction cannot be generated during the mutual action. Idling or obvious shaking will be regarded as a defective product, which is likely to cause a low yield rate and increase the cost.

因此，為解決上述問題，本領域亟需一種新穎且能克服因製造公差大所造成的空行程等困擾的折疊式鉸鏈。Therefore, in order to solve the above problems, there is an urgent need in the art for a folding hinge that is novel and can overcome the problems of idle travel caused by large manufacturing tolerances.

如圖1及圖2所示，該固定片42的數量為四片，且在相鄰的兩固定片42之間各自設有供該第一軸桿141和該第二軸桿142穿設與連動的一摩擦墊片162。As shown in FIG. 1 and FIG. 2 , the number of the fixing pieces 42 is four, and between two adjacent fixing pieces 42 are respectively provided for the first shaft 141 and the second shaft 142 to pass through and A friction pad 162 is linked.

其中，各該摩擦墊片162的至少一側面開設排列成一環形且供潤滑油脂容置的複數個儲油孔162a，以提供與相鄰的該固定片161的潤滑效果，使該第一軸桿141和該第二軸桿142分別透過套接的各該摩擦墊片162與相鄰的該固定片161產生摩擦扭力。Wherein, at least one side surface of each friction pad 162 is provided with a plurality of oil storage holes 162a arranged in a ring shape and for accommodating lubricating grease, so as to provide a lubricating effect with the adjacent fixing plate 161, so that the first shaft rod 141 and the second shaft rod 142 respectively generate frictional torsion with the adjacent fixing plate 161 through the sleeved friction pads 162 .

該本體1依照前述說明組立後的立體型態，即顯示於如圖2A，以便隨後的該第一折疊組件2和該第二折疊組件3的裝設。The three-dimensional form of the main body 1 after being assembled according to the foregoing description is shown in FIG. 2A , so as to facilitate the subsequent installation of the first folding element 2 and the second folding element 3 .

該第一折疊組件2包括一第一擺片連桿21，一第一弧形擺臂22，一第一滑動臂23以及一第一顯示撐板24。The first folding assembly 2 includes a first swing piece link 21 , a first arc swing arm 22 , a first sliding arm 23 and a first display support plate 24 .

其中該第一弧形擺臂22的一端與該左側座體11轉動連接，而另一端則與該第一擺片連桿21轉動連接；該第一滑動臂23的一端與該雙軸連動機構14的該第一軸桿141固接，而另一端則與該第一擺片連桿21滑動連接。One end of the first arc-shaped swing arm 22 is rotatably connected with the left seat body 11 , and the other end is rotatably connected with the first swing piece link 21 ; one end of the first sliding arm 23 is connected with the biaxial linkage mechanism The first shaft rod 141 of 14 is fixedly connected, and the other end is slidably connected with the first swing piece link 21 .

其中該第一滑動臂23和該第一弧形擺臂22在該本體1上的旋轉軸心相互平行且不重合，使該第一折疊組件2相對於該本體1轉動時能夠產生長度變化。The rotation axes of the first sliding arm 23 and the first arc swing arm 22 on the body 1 are parallel to each other and do not overlap, so that the length of the first folding assembly 2 can change relative to the body 1 when rotated.

該第一顯示撐板24一端與該第一擺片連桿21滑動連接，而另一端則與該本體1，例如該左側座體11和該右側座體13轉動連接。One end of the first display support plate 24 is slidably connected with the first pendulum link 21 , and the other end is rotatably connected with the main body 1 , for example, the left seat body 11 and the right seat body 13 .

因此，當該第一折疊組件2相對於該本體1轉動時，該第一顯示撐板24能夠在第一滑動臂23的驅動力下相對於該第一擺片連桿21轉動，以便對一可撓性螢幕形成支撐作用或與該本體1圍成用於容納該可撓性螢幕的一容納空間。Therefore, when the first folding assembly 2 is rotated relative to the main body 1, the first display support plate 24 can be rotated relative to the first rocker link 21 under the driving force of the first sliding arm 23, so as to align a The flexible screen forms a supporting function or forms an accommodating space with the main body 1 for accommodating the flexible screen.

具體來說，該第一折疊組件2中的該第一擺片連桿21、該第一弧形擺臂22和該第一滑動臂23利用轉動連接和滑動連接方式可以構成一曲柄滑塊機構。Specifically, the first swing piece link 21 , the first arc swing arm 22 and the first sliding arm 23 in the first folding assembly 2 can form a crank-slider mechanism by means of rotational connection and sliding connection. .

也就是說，當外力作用在第一擺片連桿21上使其旋轉時，利用該第一擺片連桿21和該第一滑動臂23的滑動配合，該第一擺片連桿21會驅動該第一滑動臂23同步旋轉，同時，該第一擺片連桿21也會帶動該第一弧形擺臂22旋轉。That is to say, when an external force acts on the first pendulum link 21 to make it rotate, the first pendulum link 21 will rotate through the sliding cooperation between the first pendulum link 21 and the first sliding arm 23 . The first sliding arm 23 is driven to rotate synchronously, and at the same time, the first swing piece link 21 also drives the first arc swing arm 22 to rotate.

前已述及，該第一滑動臂23和該第一弧形擺臂22兩者在該本體1上的旋轉軸心為相互平行且不重合，因此在前述旋轉過程中，第一擺片連桿21會相對於該第一滑動臂23滑動，導致第一擺片連桿21和第一弧形擺臂22之間的夾角會產生變化，最終導致第一擺片連桿21和第一弧形擺臂22構成的一連桿機構產呈伸展或收縮作用；亦即該第一折疊組件2的長度會有所增加或縮減。由於該第一顯示撐板24與該本體1轉動連接，且該第一顯示撐板24與該第一擺片連桿21滑動連接，因此該第一弧形擺臂22與該第一擺片連桿21之間的夾角產生變化後，該第一擺片連桿21可驅動該第一顯示撐板24旋轉。As mentioned above, the rotation axes of the first sliding arm 23 and the first arc-shaped swing arm 22 on the main body 1 are parallel to each other and do not coincide with each other. The rod 21 will slide relative to the first sliding arm 23, resulting in a change in the angle between the first pendulum link 21 and the first arc-shaped pendulum arm 22, and finally the first pendulum link 21 and the first arc A link mechanism formed by the shaped swing arm 22 can be extended or retracted; that is, the length of the first folding component 2 will be increased or decreased. Since the first display support plate 24 is rotatably connected with the main body 1, and the first display support plate 24 is slidably connected with the first swing piece link 21, the first arc swing arm 22 is connected with the first swing piece After the angle between the connecting rods 21 is changed, the first swing piece connecting rod 21 can drive the first display support plate 24 to rotate.

同樣地，該第二折疊組件3包括一第二擺片連桿31，一第二弧形擺臂32，一第二滑動臂33以及一第二顯示撐板34。Similarly, the second folding assembly 3 includes a second swing piece link 31 , a second arc swing arm 32 , a second sliding arm 33 and a second display support plate 34 .

其中該第二弧形擺臂32的一端與該左側座體11轉動連接，而另一端則與該第二擺片連桿31轉動連接；該第二滑動臂33的一端與該雙軸連動機構14的該第二軸桿142固接，而另一端則與該第二擺片連桿31滑動連接。One end of the second arc-shaped swing arm 32 is rotatably connected with the left seat body 11, and the other end is rotatably connected with the second swing piece link 31; one end of the second sliding arm 33 is connected with the biaxial linkage mechanism The second shaft rod 142 of 14 is fixedly connected, and the other end is slidably connected with the second swing piece link 31 .

其中該第二滑動臂33和該第二弧形擺臂32在該本體1上的旋轉軸心相互平行且不重合，使該第二折疊組件3相對於該本體1轉動時能夠產生長度變化。The rotation axes of the second sliding arm 33 and the second arc swing arm 32 on the main body 1 are parallel to each other and do not overlap each other, so that the length of the second folding assembly 3 can change relative to the main body 1 when rotated.

該第二顯示撐板34一端與該第二擺片連桿31滑動連接，而另一端則與該本體1，例如左側座體11和右側座體13轉動連接。One end of the second display support plate 34 is slidably connected with the second swing piece link 31 , and the other end is rotatably connected with the main body 1 , for example, the left seat body 11 and the right seat body 13 .

因此，當該第二折疊組件3相對於該本體1轉動時，該第二顯示撐板34能夠在第二滑動臂33的驅動力下相對於該第二擺片連桿31轉動，以便對該可撓性螢幕形成支撐作用或與該本體1圍成用於容納該可撓性螢幕的該容納空間。Therefore, when the second folding assembly 3 is rotated relative to the main body 1, the second display support plate 34 can be rotated relative to the second rocker link 31 under the driving force of the second sliding arm 33, so that the The flexible screen forms a supporting function or forms the accommodating space with the main body 1 for accommodating the flexible screen.

具體來說，該第二折疊組件3中的該第二擺片連桿31、該第二弧形擺臂32和該第二滑動臂33利用轉動連接和滑動連接方式可以構成另一曲柄滑塊機構。Specifically, the second swing piece link 31 , the second arc swing arm 32 and the second sliding arm 33 in the second folding assembly 3 can form another crank slider by means of rotational connection and sliding connection mechanism.

也就是說，當外力作用在第二擺片連桿31上使其旋轉時，利用該第二擺片連桿31和該第二滑動臂33的滑動配合，該第二擺片連桿31會驅動該第二滑動臂33同步旋轉，同時，第二擺片連桿31也會帶動該第二弧形擺臂32旋轉。That is to say, when an external force acts on the second pendulum link 31 to make it rotate, the second pendulum link 31 will rotate through the sliding cooperation between the second pendulum link 31 and the second sliding arm 33 . The second sliding arm 33 is driven to rotate synchronously, and at the same time, the second swing piece link 31 also drives the second arc swing arm 32 to rotate.

請再參閱圖2A至圖2C，該第一滑動臂23和該第二滑動臂33各自的一端均已固接於對應的該第一軸桿141與該第二軸桿142(顯示於圖2A)。Please refer to FIGS. 2A to 2C again, one end of each of the first sliding arm 23 and the second sliding arm 33 has been fixed to the corresponding first shaft 141 and the second shaft 142 (shown in FIG. 2A ) ).

接著，將該第一弧形擺臂22和該第二弧形擺臂32各自的一端轉動連接至該左側座體11的對應側(顯示於圖2B)。Next, one end of each of the first arc swing arm 22 and the second arc swing arm 32 is rotatably connected to the corresponding side of the left seat body 11 (shown in FIG. 2B ).

接續如圖2C所示，將該第一滑動臂23的另一端套設於該第一擺片連桿21預設的一第一滑槽211內，另將該第二滑動臂33的另一端套設於套設於該第二擺片連桿31預設的一第二滑槽311內；隨後，將該第一弧形擺臂22和該第二弧形擺臂32各自的另一端轉動連接至對應的該第一擺片連桿21和該第二擺片連桿31(顯示於圖2C)。Continuing as shown in FIG. 2C , the other end of the first sliding arm 23 is sleeved in a predetermined first chute 211 of the first pendulum link 21 , and the other end of the second sliding arm 33 is sleeved in a predetermined second chute 311 sleeved on the second swing piece link 31; then, the other ends of the first arc swing arm 22 and the second arc swing arm 32 are rotated Connected to the corresponding first wobble link 21 and the second wobble link 31 (shown in FIG. 2C ).

另請參閱圖1和圖2，該第一滑槽211和該第二滑槽311內另行設置由聚甲醛(Polyoxymethylene，縮寫為POM)材料製成且各自供該第一滑動臂23和該第二滑動臂33插設的的一對滑軌5，以提供高剛性、自潤性、低摩擦和優異的尺寸穩定性等功能，並克服由金屬製成的該等該滑動臂23、33和該等擺片連桿21、31在滑移過程中容易發出異音，以及因金屬磨損所產生金屬粉塵堆積等缺陷。Please also refer to FIG. 1 and FIG. 2 , the first chute 211 and the second chute 311 are separately provided with polyoxymethylene (Polyoxymethylene, abbreviated as POM) material and are respectively provided for the first sliding arm 23 and the first sliding arm 23 and the first sliding arm 23 . A pair of sliding rails 5 inserted into the two sliding arms 33 to provide functions such as high rigidity, self-lubrication, low friction and excellent dimensional stability, and to overcome the sliding arms 23, 33 and The pendulum links 21 and 31 are prone to abnormal noise during the sliding process, and defects such as metal dust accumulation due to metal wear.

隨後，將該第一顯示撐板24和該第二顯示撐板34各自內側的兩端各自轉動連接至該左側座體11和該右側座體13的對應側；另將該第一顯示撐板24和該第二顯示撐板34各自外側的兩端各自滑動連接至該第一擺片連桿21和該第二擺片連桿31的對應側(顯示於圖2C)。Then, the two inner ends of the first display support plate 24 and the second display support plate 34 are respectively connected to the corresponding sides of the left seat body 11 and the right seat body 13 by rotation; 24 and the two outer ends of the second display support plate 34 are respectively slidably connected to the corresponding sides of the first wobble link 21 and the second wobble link 31 (shown in FIG. 2C ).

最後，將前述折疊式鉸鏈倒置後，並將該限位件4固接於該本體1的背面，例如左側座體11上，該限位件4兩側對應該第一弧形擺臂22和該第二弧形擺臂32各自底部的一圓弧面伸出與各該圓弧面彈性抵接的至少一彈性臂41。Finally, after inverting the aforementioned folding hinge, the limiting member 4 is fixed to the back of the main body 1, for example, on the left seat body 11, and the two sides of the limiting member 4 correspond to the first arc-shaped swing arm 22 and At least one elastic arm 41 elastically abutting against each of the circular arc surfaces protrudes from a circular arc surface at the bottom of each of the second arc-shaped swing arms 32 .

如圖1、圖2和圖4所示，該彈性臂41的數量為兩支，而該第一弧形擺臂22和該第二弧形擺臂32的底面則各自對應開設供該等彈性臂41套設的一對臂槽221、321(顯示於圖3)，以及與各對臂槽221、321相連通且供對應的該等彈性臂41插設的一對插孔222、322。As shown in FIG. 1 , FIG. 2 and FIG. 4 , the number of the elastic arms 41 is two, and the bottom surfaces of the first arc swing arm 22 and the second arc swing arm 32 are correspondingly provided for the elastic A pair of arm grooves 221 , 321 (shown in FIG. 3 ) sleeved on the arm 41 , and a pair of insertion holes 222 , 322 communicated with each pair of arm grooves 221 , 321 and for inserting the corresponding elastic arms 41 .

在所示實施例中，該折疊式鉸鏈的整體要求薄型化，所以該本體1，該等弧形擺臂22、32，該等滑動臂23、33，以及該等顯示撐板24、34都是由金屬射出成型製造而成，其中，又以該本體1的該左側座體11與該等弧形擺臂22、32的內側兩端各自是以一弧形榫114和一供該弧形榫114對應樞接的弧形槽223或323形成一虛擬軸式的轉動連接，以致這兩個零件之間的間隙比較容易產生一空行程，尤其從摺疊狀態之初步張開時，形成該空行程情況最明顯，所以需要該限位件4抵壓住該等弧形擺臂22、32的各外弧面，使該等元件在相對轉動的過程中，不管是從一摺疊狀態相對轉動成一展開狀態，或是從該展開狀態相對轉動成該摺疊狀態時，都能讓該限位件4抵住該等弧形擺臂22、32，以防止前述間隙造成的影響，進而在該限位件4與該等弧形擺臂22、32具有足夠的摩擦力產生。In the illustrated embodiment, the whole of the folding hinge is required to be thin, so the body 1, the arc-shaped swing arms 22, 32, the sliding arms 23, 33, and the display braces 24, 34 are all It is manufactured by metal injection molding, wherein the left side body 11 of the main body 1 and the inner ends of the arc-shaped swing arms 22 and 32 are respectively an arc-shaped tenon 114 and an arc-shaped The tenon 114 corresponds to the pivoted arc-shaped groove 223 or 323 to form a virtual shaft-type rotational connection, so that the gap between the two parts is relatively easy to generate an empty stroke, especially when initially opened from the folded state. Obviously, it is necessary for the limiting member 4 to press against the outer arc surfaces of the arc-shaped swing arms 22 and 32, so that in the process of relative rotation of these elements, no matter whether they are relatively rotated from a folded state to an unfolded state, Or when it is relatively rotated from the unfolded state to the folded state, the limiting member 4 can be pressed against the arc-shaped swing arms 22 and 32 to prevent the influence caused by the aforementioned gap, and then the limiting member 4 and the The arc-shaped swing arms 22, 32 have sufficient friction force to be generated.

再者，由於該折疊式鉸鏈在該展開或摺疊狀態時的要求是愈來愈薄，導致該左側座體11的厚度亦要變薄，致使該等弧形擺臂22、32的各該弧形槽223、323由傳統的一半圓弧形變成一劣弓形，如此在操作上，施力將整體翻轉至近摺疊狀或是摺疊狀態之初步張開時，各該弧形槽223、323與該左側座體11的該弧形榫114之間的接觸面較少，因此只要施力不均衡，就容易造成該等弧形槽223中的至少一個與對應的該弧形榫114鬆脫，所以透過增加該限位件4抵住該等弧形擺臂22、32的劣弓形部位，即能防止該等弧形擺臂22、32和該左側座體11鬆脫的情況。Furthermore, since the requirements of the folding hinge in the unfolded or folded state are getting thinner and thinner, the thickness of the left seat body 11 is also thinner, so that the arcs of the arc-shaped swing arms 22 and 32 are The grooves 223 and 323 are transformed from the traditional semi-circular arc shape into an inferior arcuate shape. In this way, in operation, when a force is applied to turn the whole body to a nearly folded state or the initial opening of the folded state, the arc-shaped grooves 223 and 323 and the left seat The contact surface between the arc-shaped tenons 114 of the body 11 is less, so as long as the force is unbalanced, at least one of the arc-shaped grooves 223 and the corresponding arc-shaped tenon 114 are easily loosened, so by increasing the The limiting member 4 abuts against the inferior arcuate parts of the arc-shaped swing arms 22 , 32 , which can prevent the arc-shaped swing arms 22 , 32 and the left seat body 11 from loosening.

其中，該第一弧形擺臂22的外側兩端是以一第一固定軸銷212樞接於該第一擺片連桿21上，以形成前述轉動連接；同樣地，該第二弧形擺臂32的外側兩端則是以一第二固定軸銷312樞接於該第二擺片連桿31上，以形成前述轉動連接。Wherein, the outer ends of the first arc-shaped swing arm 22 are pivotally connected to the first swing piece link 21 by a first fixed shaft pin 212 to form the aforementioned rotational connection; similarly, the second arc-shaped The two outer ends of the swing arm 32 are pivotally connected to the second swing piece link 31 by a second fixed shaft pin 312 to form the aforementioned rotational connection.

再者，該第一顯示撐板24的內側兩端各自是以一第一弧形鉤241穿設於該左側座體11的一第一弧形凹槽115和該右側座體13的一第二弧形凹槽131內，以形成前述轉動連接；同樣地，該第二顯示撐板34的內側兩端則各自是以一第二弧形鉤341穿設於該左側座體11的一第三弧形凹槽116和該右側座體13的一第四弧形凹槽132內，以形成前述虛擬軸式的轉動連接。Furthermore, both ends of the inner side of the first display support plate 24 are respectively a first arc-shaped hook 241 passing through a first arc-shaped groove 115 of the left seat body 11 and a first arc groove 115 of the right seat body 13 . The two arc-shaped grooves 131 are in the two arc-shaped grooves 131 to form the aforementioned rotational connection; similarly, the inner two ends of the second display support plate 34 are respectively inserted through a second arc-shaped hook 341 on a first part of the left seat body 11 . The three arc-shaped grooves 116 and a fourth arc-shaped groove 132 of the right seat body 13 are formed to form the aforementioned virtual shaft-type rotational connection.

此外，該第一顯示撐板24的外側兩端各自的一第一接孔242供一第三固定軸銷243穿設與固定後，該第三固定軸銷243穿入該第一擺片連桿21的一第一弧形限位槽213內，以形成前述滑動連接；同樣地，該第二顯示撐板34的外側兩端各自的一第二接孔342供一第四固定軸銷343穿設與固定後，該第四固定軸銷343穿入該第二擺片連桿31的一第二弧形限位槽313內，以形成前述滑動連接。In addition, a first connecting hole 242 on each of the two outer ends of the first display support plate 24 is used for a third fixing shaft pin 243 to pass through and be fixed, and the third fixing shaft pin 243 is inserted into the first swing piece to connect A first arc-shaped limiting groove 213 of the rod 21 to form the aforementioned sliding connection; similarly, a second connecting hole 342 at each of the two outer ends of the second display support plate 34 is provided for a fourth fixing shaft pin 343 After being threaded and fixed, the fourth fixing shaft pin 343 penetrates into a second arc-shaped limiting groove 313 of the second pendulum link 31 to form the aforementioned sliding connection.

如圖4所示，即根據前述的說明將該本體1、該第一折疊組件2和該第二折疊組件3組裝完成後的立體圖。As shown in FIG. 4 , which is a perspective view of the assembled body 1 , the first folding assembly 2 and the second folding assembly 3 according to the foregoing description.

從圖中可以清楚看出，該第一顯示撐板24介於該第一擺片連桿21與該本體1之間，並與兩者形成一齊平型態；而該第二顯示撐板34則介於該第二擺片連桿31與該本體1之間，並與兩者亦形成一齊平型態。It can be clearly seen from the figure that the first display support plate 24 is between the first swing piece link 21 and the main body 1, and forms a flush shape with both; and the second display support plate 34 It is located between the second pendulum link 31 and the main body 1, and forms a flush shape with both.

請參閱圖5至圖7B，其顯示該折疊式鉸鏈由該展開狀態轉動至該折疊狀態的側視圖及相關的剖面圖。Please refer to FIGS. 5 to 7B , which show side views and related cross-sectional views of the folding hinge rotated from the unfolded state to the folded state.

如圖5所示，該折疊式鉸鏈是位於一可撓性螢幕6的外側，而該等第三和第四固定軸銷243、343各自在對應的該第一和第二弧形限位槽213、313內的上方。As shown in FIG. 5 , the foldable hinge is located on the outer side of a flexible screen 6, and the third and fourth fixed shaft pins 243, 343 are respectively in the corresponding first and second arc-shaped limiting grooves Above inside 213 and 313.

如圖5A所示，該等第一和第二滑動臂23、33各自的一端與對應的該等第一和第二軸桿141、142固接，而另一端則各自套設於對應的該等第一、第二滑槽211、311內。As shown in FIG. 5A , one end of each of the first and second sliding arms 23 , 33 is fixedly connected with the corresponding first and second shaft rods 141 , 142 , and the other end is respectively sleeved on the corresponding Wait for the first and second chutes 211 and 311.

請結合參閱圖6至圖7B，該第一弧形擺臂22在該本體1上的旋轉軸心相較於該第一滑動臂23在該本體1上的旋轉軸心有所偏離。Please refer to FIG. 6 to FIG. 7B , the rotation axis of the first arc swing arm 22 on the main body 1 is deviated from the rotation axis of the first sliding arm 23 on the main body 1 .

因此，當該折疊式鉸鏈被折疊時，外力作用在該第一擺片連桿21上，使其沿順時針方向旋轉，同時，該第一擺片連桿21會驅動該第一弧形擺臂22和該第一滑動臂23沿著順時針方向旋轉，在此運動過程中，該第一擺片連桿21和該第一弧形擺臂22之間的夾角變大，使該第一擺片連桿21和該第一滑動臂23所構成的一連桿機構伸展，以增加第一折疊組件2的長度。Therefore, when the folding hinge is folded, an external force acts on the first pendulum link 21 to rotate clockwise, and at the same time, the first pendulum link 21 drives the first arc pendulum The arm 22 and the first sliding arm 23 rotate in the clockwise direction. During this movement, the angle between the first swing piece link 21 and the first arc swing arm 22 becomes larger, so that the first swing arm 22 becomes larger. A link mechanism formed by the rocker link 21 and the first sliding arm 23 is extended to increase the length of the first folding assembly 2 .

同樣地，該第二弧形擺臂32在該本體1上的旋轉軸心相較於該第二滑動臂33在該本體1上的旋轉軸心亦有所偏離，且該第一軸桿141被該第一滑動臂23帶動的同時，透過該傳動機構，使該第二軸桿142具有相反方向，例如逆時針方向旋轉功能。Similarly, the rotation axis of the second arc-shaped swing arm 32 on the main body 1 is also deviated from the rotation axis of the second sliding arm 33 on the main body 1 , and the first shaft 141 While being driven by the first sliding arm 23, through the transmission mechanism, the second shaft rod 142 has the function of rotating in the opposite direction, eg, counterclockwise.

前已述及，當該第一顯示撐板24與該第一擺片連桿21滑動連接，且該第一顯示撐板24與該本體1以虛擬軸式的轉動連接時；請參閱圖6即圖7，該折疊式鉸鏈被折疊的過程中，該第一擺片連桿21沿順時針方向轉動，且沿著該第一滑動臂23向外滑動，並帶動該第一弧形擺臂22旋轉。As mentioned above, when the first display support plate 24 is slidably connected to the first pendulum link 21, and the first display support plate 24 is connected to the main body 1 in a virtual axis-like rotation; please refer to FIG. 6 7, when the folding hinge is folded, the first swing link 21 rotates clockwise, and slides outward along the first sliding arm 23, and drives the first arc swing arm 22 spins.

此時，該第三固定軸銷243抵推該第一弧形限位槽213的側壁，並在該第一弧形限位槽213內滑動，以使相對於該第一擺片連桿21沿著順時針方向旋轉，從而能夠在該第一顯示撐板24和該本體1之間逐漸形成用於容納該可撓性螢幕6的彎曲部分的該容納空間。At this time, the third fixed shaft pin 243 pushes against the side wall of the first arc-shaped limiting slot 213 and slides in the first arc-shaped limiting slot 213 , so that the first swing piece link 21 is relatively By rotating in the clockwise direction, the accommodating space for accommodating the curved portion of the flexible screen 6 can be gradually formed between the first display support plate 24 and the main body 1 .
