Description

複合移動轉動運動之樞軸裝置Pivot device for compound movement and rotation

本創作係有關於一種樞軸裝置；特別是指一種樞軸的作動臂可產生移動運動結合轉動運動，以減少組件組配/運動空間之技術。This creation is related to a pivot device; in particular, it refers to a technology in which a pivotal actuating arm can generate moving motion combined with rotating motion to reduce the assembly/movement space of components.

應用因外力可往復轉動自如的樞軸或轉軸，來配裝在電子器物上，例如行動電話、筆記型電腦、PDA、電子書等，使其蓋或顯示螢幕可轉動而具有開、閉作用，係已為習知技藝。例如，台灣第97222022號「轉軸結構」、第98207366號「樞軸結構」等專利案，係提供了典型的實施例。Apply a pivot or rotating shaft that can reciprocate freely due to external force to be fitted to electronic utensils, such as mobile phones, laptops, PDAs, e-books, etc., so that the cover or display screen can be turned to open and close. The department has learned the skills. For example, Taiwan Patent No. 97222022 "Rotating Shaft Structure", No. 98207366 "Pivot Structure" and other patent cases provide typical examples.

為了使電子器物的顯示模組（例如，螢幕）及/或機體模組在使用方面具備有更多的操作模式和應用範圍，習知技藝也已揭露一種在顯示模組和機體模組之間設置雙轉軸，使顯示模組及/或機體模組可產生不同操作模式或轉動角度的結構。例如，台灣第99211350號「雙樞軸樞紐器」、第99225737號「雙軸向樞紐器」、US 7512426 B2「MOBILE COMMUNICATIONS DEVICE WITH SYNCHRONISING HINGE」專利案等，係提供了典型的實施例。In order to enable the display module (for example, the screen) and/or the body module of the electronic device to have more operation modes and application ranges in use, the prior art has also disclosed a method between the display module and the body module. With dual rotating shafts, the display module and/or the body module can produce structures with different operation modes or rotation angles. For example, Taiwan Patent No. 99211350 "Dual Axial Hub", No. 99225737 "Biaxial Hub", US 7512426 B2 "MOBILE COMMUNICATIONS DEVICE WITH SYNCHRONISING HINGE" patent cases, etc., provide typical examples.

一個有關這類樞軸組件組合撓性螢幕或屏幕在操作、結構設計方面的課題是，實務上必須應用至少一組雙轉軸組件配合轉軸位移運動，才能提供撓性螢幕的彎折作動空間；例如，台灣第105126016號「軸心位移樞軸器」、第107134205號「折疊式裝置的轉軸模組」、第108207352號「偏位旋轉的雙軸同動鉸鍊」專利案等，係提供了可行的實施例。A subject related to the operation and structural design of flexible screens or screens combined with such pivot components is that in practice, at least one set of dual-axis components must be used to cooperate with the displacement movement of the pivots to provide the flexible screen's bending movement space; for example, , Taiwan’s patents No. 105126016 "Axial Displacement Pivot", No. 107134205 "Rotation Module for Folding Device", and No. 108207352 "Biaxial Simultaneous Hinge with Offset Rotation", etc., provide feasible Examples.

舊法也揭露了一種應用多個轉軸或連桿、齒輪（或螺旋齒輪及/或齒條）、鏈片或聯結組件的結構組合，來傳遞動力，使雙轉軸同步轉動的技術結構。The old method also discloses a technical structure that uses a combination of multiple rotating shafts or connecting rods, gears (or helical gears and/or racks), chains or coupling components to transmit power and make the two rotating shafts rotate synchronously.

但是，就像那些熟習此技藝的人所知悉，在考量樞軸器或其相關結合組件在符合電子器物輕巧、薄型化（或精簡化）的造型條件下，習知技藝的結構和其配合型態複雜；以及，提供撓性螢幕彎折收、合操作的過程，雙轉軸或樞軸裝置的移位運動，也占用了較大的（運動）空間或具有較大材積；而這種情形並不是我們所期望的。However, as those who are familiar with this art know, considering that the pivot or its related components meet the conditions of lightness and thinness (or simplified) of electronic objects, the structure of the art and its matching type are considered. The state is complicated; and, the process of providing flexible screen folding and closing operations, the displacement movement of the dual-rotation or pivot device also takes up a large (movement) space or has a large volume; and this situation does not Not what we expected.

代表性的來說，這些參考資料顯示了有關轉軸或樞軸和其相關結合組件在使用和結構設計方面的情形。如果重行設計考量該轉軸和相關組件結構，以及上述的應用情形，使其不同於習用者，將可改變它的使用型態，增加它的應用範圍，而有別於舊法。例如，考量使樞軸裝置或其相關結合組件符合電子器物輕巧、薄型化造型要求和組裝簡便的結構設計條件，使樞軸器可應用在雙屏或撓性螢幕的彎折展開/收合操作等作用；或進一步使樞軸裝置或組件之間的配合間距、運動範圍被儘可能減小，以利於使整個電子器物獲得簡潔、設計美感的外觀視覺效果，改善習知組件配合佔據較大（運動）空間或體積等作用。而這些課題在上述的參考資料中均未被具體教示或揭露。Typically, these reference materials show the use and structural design of the shaft or pivot and its related combined components. If the redesign takes into account the structure of the shaft and related components, as well as the above-mentioned application, to make it different from the habitual user, it will be able to change its usage pattern and increase its scope of application, which is different from the old method. For example, considering that the pivot device or its related combined components meet the requirements of light, thin shape and easy assembly of electronic utensils, the pivot device can be applied to the folding and unfolding operations of dual screens or flexible screens. Or to further reduce the matching distance and movement range between pivot devices or components as much as possible, so as to facilitate the appearance and visual effect of the entire electronic device with a simple and aesthetic design, and improve the coordination of conventional components to occupy a larger ( Movement) space or volume. These issues are not specifically taught or exposed in the above reference materials.

例如，作動臂21可設置至少一個或複數個孔洞21a，用以樞接連動部55。連動部55一端樞接作動臂21的孔洞21a，另一端樞接滑動部96；滑動部96和作動臂21可固定在電子器物的機體90上，使滑動部96、作動臂21（或總成100）可隨人員操作機體90執行打開、閉合機制的運動而運動。For example, the actuating arm 21 may be provided with at least one or a plurality of holes 21 a for pivotally connecting the linkage part 55. One end of the linkage part 55 is pivotally connected to the hole 21a of the actuating arm 21, and the other end is pivotally connected to the sliding part 96; the sliding part 96 and the actuating arm 21 can be fixed on the body 90 of the electronic appliance, so that the sliding part 96, the actuating arm 21 (or assembly 100) It can move as the person operates the body 90 to perform the movement of the opening and closing mechanism.

請參考第3、4圖，描繪了作動臂21位在180度位置（或機體90打開位置）的結構情形；以及，第4圖顯示了橋接器25的栓27的位置。所述的栓27的一端位在固定座10的凹槽13裏面，另一端頂在作動臂21的側壁21b上。為了方便說明，栓27位在固定座凹槽13的一端定義為第一端27a，栓27的另一端定義為第二端27b。Please refer to Figures 3 and 4, which depict the structure of the actuator arm 21 at the 180 degree position (or the body 90 open position); and Figure 4 shows the position of the bolt 27 of the bridge 25. One end of the bolt 27 is located in the groove 13 of the fixing base 10, and the other end abuts on the side wall 21 b of the actuating arm 21. For the convenience of description, one end of the bolt 27 located in the groove 13 of the fixing seat is defined as a first end 27a, and the other end of the bolt 27 is defined as a second end 27b.

請參閱第5圖，當人員操作或拉動作動臂21（或機體90）時，作動臂21的（弧形）導部22會相對沿著橋接器25的（弧形）牽引部28移動，使作動臂21從180度位置依一虛擬軸心運動（及/或移動、轉動運動）到100度（或110度）位置，並且使栓27逐漸接近及/或到達作動臂21的斜面24的位置。Please refer to Figure 5, when a person operates or pulls the boom 21 (or body 90), the (arc) guide portion 22 of the actuating arm 21 will move relative to the (arc) traction portion 28 along the bridge 25, so that The actuating arm 21 moves from a position of 180 degrees (and/or moving, rotating) to a position of 100 degrees (or 110 degrees), and the bolt 27 gradually approaches and/or reaches the position of the inclined surface 24 of the actuating arm 21 .

可了解的是，作動臂21的導部22沿橋接器25的牽引部28朝總成100兩邊區域（或外部區域）運動的機制，相對的也輔助增加了空間，來作為收容撓性螢幕彎折區域的作用。It can be understood that the mechanism by which the guide portion 22 of the actuating arm 21 moves along the traction portion 28 of the bridge 25 toward the two side areas (or outer areas) of the assembly 100, relatively also assists in increasing the space to accommodate the flexible screen curve. The role of the folding area.

在人員繼續操作作動臂21朝閉合位置運動時，所述施力使栓27的第一端27a頂推固定座10，迫使固定座10反向推動栓27沿斜面14（順著導引面15）產生軸向運動（所述的軸向是指栓27的軸線方向），相對使栓27的第二端27b沿著作動臂21的斜面24運動，逐漸朝作動臂21的凹槽23接近。因此，可了解的是斜面24是從作動臂21的側壁21b區域朝凹槽23（或作動臂21內部）方向傾斜的型態，以利於栓27的第二端27b進入作動臂21的凹槽23。When the personnel continue to operate the actuating arm 21 to move toward the closed position, the force exerts the first end 27a of the bolt 27 to push the fixing seat 10, forcing the fixing seat 10 to push the bolt 27 along the slope 14 (along the guide surface 15). ) Produces an axial movement (the axial direction refers to the axial direction of the bolt 27), and relatively makes the second end 27b of the bolt 27 move along the inclined surface 24 of the working arm 21 and gradually approach the groove 23 of the working arm 21. Therefore, it can be understood that the inclined surface 24 is inclined from the side wall 21b area of the actuating arm 21 toward the groove 23 (or inside the actuating arm 21) to facilitate the second end 27b of the bolt 27 to enter the groove of the actuating arm 21 twenty three.

請參考第6圖，描繪了人員操作作動臂21到達80度位置（或上述所稱的設定位置）時，栓27的第一端27a已沿著固定座斜面14被推出凹槽13，栓27的第二端27b則到達作動臂21的凹槽23位置，並且被推入作動臂凹槽23裏面，完成栓27的位置切換作用。Please refer to Figure 6, which depicts that when the operating arm 21 reaches the 80 degree position (or the above-mentioned set position), the first end 27a of the bolt 27 has been pushed out of the groove 13 along the inclined surface 14 of the fixing seat, and the bolt 27 The second end 27b reaches the position of the groove 23 of the actuating arm 21, and is pushed into the groove 23 of the actuating arm to complete the position switching function of the pin 27.

請參閱第7、8圖，當人員操作作動臂21朝閉合位置運動時，應用橋接器25的軸柱26樞接固定座10的軸孔12形成轉動支點，而容許作動臂21位在0度位置（或機體90閉合位置）的作用；例如，第9圖所描繪的結構情形，而完成作動臂21（或機體90）的開、合機制。Please refer to Figures 7 and 8, when a person operates the actuator arm 21 to move toward the closed position, the shaft 26 of the bridge 25 is pivotally connected to the shaft hole 12 of the fixing base 10 to form a pivot point, and the actuator arm 21 is allowed to be positioned at 0 degrees The function of the position (or the closed position of the body 90); for example, the structure depicted in Figure 9 completes the opening and closing mechanism of the actuating arm 21 (or the body 90).

Compared with the old method, the pivot device includes the following advantages and considerations:

1.該固定座10和運動模組20共同構成的總成100的組合結構已被重行設計考量，而構成可轉動及/或移動作用的結構型態；例如，固定座10設置軸孔12樞接橋接器25的軸柱26；作動臂21配置導部22組合橋接器25的牽引部28，而構成可相對運動的作用；固定座10設置凹槽13、斜面14，配合作動臂21設置凹槽23、斜面24，共同容許橋接器25的栓27運動於作動臂21和固定座10之間，來控制作動臂21的移動運動及/或轉動運動等部分，明顯不同於習知技藝的結構型態。1. The combined structure of the assembly 100 formed by the fixed base 10 and the motion module 20 has been redesigned to form a rotatable and/or movable structure; for example, the fixed base 10 is provided with a shaft hole 12 pivot Connecting the axle column 26 of the bridge 25; the actuating arm 21 is configured with a guide portion 22 combined with the traction portion 28 of the bridge 25 to form a relative movable function; the fixing seat 10 is provided with a groove 13 and an inclined surface 14, and the movable arm 21 is equipped with a concave The groove 23 and the inclined surface 24 together allow the bolt 27 of the bridge 25 to move between the actuator arm 21 and the fixed base 10 to control the movement and/or rotation of the actuator arm 21, which is obviously different from the conventional structure Type.

2.該固定座10、運動模組20的組合結構，適於應用在雙屏或撓性螢幕的彎折展開/收合操作等作用；並且，進一步使總成100或組件之間的配合間距、運動範圍被儘可能減小，以利於使整個電子器物獲得簡潔、設計美感的外觀視覺效果，改善習知組件配合佔據較大（運動）空間或體積等作用，明顯不同於習用者，而改變它的使用型態，增加它的應用範圍。2. The combined structure of the fixed base 10 and the motion module 20 is suitable for the functions of double screens or flexible screens for folding and unfolding/folding operations; and further increases the matching distance between the assembly 100 or the components , The range of motion is reduced as much as possible to facilitate the appearance and visual effect of concise and aesthetic design of the entire electronic device, and to improve the role of conventional components occupying a larger (movement) space or volume, which is obviously different from those of the user. Its use type increases its scope of application.
