按，現今掀蓋式電子產品，如：筆記型電腦、智慧型手機…等，係由基座以及上蓋所組成，且部分掀蓋式電子產品之上蓋可翻掀至基座底面，讓掀蓋式電子產品可做為平板電腦使用，或是兩片觸控式螢幕組合而成的摺疊式平板電腦，可平行展開使用。一般而言，此種可做為平板電腦使用之掀蓋式電子產品，係利用雙軸之轉軸裝置來達成其翻掀動作，此種轉軸裝置係利用軸筒樞接第一轉軸以及第二轉軸，而電子產品之上蓋與基座分別接於第一轉軸與第二轉軸，讓上蓋可翻掀至基座底面，或使上蓋由基座底面蓋合於基座表面。Press, today's clamshell electronic products, such as notebook computers, smart phones, etc., are composed of a base and an upper cover, and some of the clamshell electronic products can be flipped over the bottom of the base to allow the cover to be folded. The electronic product can be used as a tablet or a folding tablet with a combination of two touch screens, which can be used in parallel. In general, such a clamshell electronic product that can be used as a tablet computer utilizes a biaxial shaft device to achieve its turning operation. The shaft device pivots the first rotating shaft and the second rotating shaft by using a shaft cylinder. The upper cover and the base of the electronic product are respectively connected to the first rotating shaft and the second rotating shaft, so that the upper cover can be turned over to the bottom surface of the base, or the upper cover is covered by the bottom surface of the base to the surface of the base.
目前，轉軸裝置之第一轉軸與軸筒轉動之間的轉動方式可分為螺桿式、連桿式以及齒輪式等多種方式，但不論是何種方式，都是利用第一轉軸轉動時，強制帶動軸筒繞行第二轉軸，也就是第一轉軸與軸筒繞行第二轉軸為同時發生，此類轉動方式之設計，主要是因為設計者無法控制第一轉軸與軸筒轉動之作動順序以及作動角度，而利用強制帶動使其同時發生，往往導致二轉軸會承受非常大的應力，導致斷裂之情形發生，尤其在轉軸裝置啟始轉動時更加嚴重，且由於二轉軸是同時轉動，二轉軸長期使用下， 轉動角度所產生之偏差，容易發生卡死之情形，造成轉軸裝置無法使用。At present, the rotation mode between the first rotating shaft of the rotating shaft device and the rotation of the shaft cylinder can be divided into a screw type, a link type and a gear type, but in any way, when the first rotating shaft is rotated, the force is forced. Driving the shaft to bypass the second rotating shaft, that is, the first rotating shaft and the second rotating shaft of the shaft are simultaneously occurring. The design of such rotating mode is mainly because the designer cannot control the order of rotation of the first rotating shaft and the shaft. As well as the actuating angle, the use of forced driving causes them to occur at the same time, which often causes the two rotating shafts to withstand very large stresses, resulting in the occurrence of breakage, especially when the rotating shaft device starts to rotate, and since the two rotating shafts are simultaneously rotating, Long-term use of the shaft, The deviation caused by the rotation angle is prone to jamming, which makes the shaft device unusable.
是以，要如何解決上述習知之問題與缺失，即為相關業者所亟欲研發之課題。Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.
本創作之主要目的乃在於，利用軸筒之設計讓上蓋朝向基座底面翻掀時，轉軸組之第一轉軸與軸筒之間所產生之摩擦阻力小於轉軸組之第二轉軸與軸筒之間所產生之摩擦阻力，而於上蓋朝向基座表面翻掀時，第一轉軸與軸筒之間所產生之摩擦阻力大於第二轉軸與軸筒之間所產生之摩擦阻力，進而可方便控制第一轉軸轉動與軸筒繞行第二轉軸之作動順序以及作動角度。The main purpose of this creation is that when the upper cover is turned toward the bottom of the base by the design of the shaft cylinder, the frictional resistance generated between the first rotating shaft and the shaft cylinder of the rotating shaft group is smaller than the second rotating shaft and the shaft cylinder of the rotating shaft group. The frictional resistance generated between the two, when the upper cover is turned toward the surface of the base, the frictional resistance generated between the first rotating shaft and the barrel is greater than the frictional resistance generated between the second rotating shaft and the barrel, thereby facilitating control The sequence of rotation of the first rotating shaft and the second rotating shaft of the barrel and the operating angle.
為達上述目的，本創作之雙轉軸結構，至少設置有軸筒以及轉軸組，軸筒具有基部，基部上方表面形成有第一表面，下方表面形成有第二表面，第一表面一側朝向另側彎折延伸有第一抵壓部，第一抵壓部與第一表面之間形成有第一轉軸空間，第二表面一側朝向另側彎折延伸有第二抵壓部，第二抵壓部與第二表面之間形成有第二轉軸空間，第一抵壓部與第二抵壓部之延伸方向相反；轉軸組具有第一轉軸與第二轉軸，第一轉軸二側分別形成有第一軸部與第一連接部，第一軸部樞接於軸筒之第一轉軸空間，第一連接部位於軸筒一側並連接有上蓋，而第二轉軸二側分別形成有第二軸部與第二連接部，第二軸部樞接於軸筒之第二轉軸空間，第二連接部位於軸筒一側並連接有基座。In order to achieve the above object, the dual shaft structure of the present invention is provided with at least a shaft barrel and a shaft assembly. The shaft barrel has a base portion. The upper surface of the base portion is formed with a first surface, and the lower surface is formed with a second surface, and the first surface side faces the other The side bending portion has a first pressing portion, a first rotating shaft space is formed between the first pressing portion and the first surface, and the second surface side is bent toward the other side and has a second pressing portion, and the second abutting portion A second rotating shaft space is formed between the pressing portion and the second surface, and the first pressing portion and the second pressing portion extend in opposite directions; the rotating shaft group has a first rotating shaft and a second rotating shaft, and the two sides of the first rotating shaft are respectively formed with The first shaft portion and the first connecting portion are pivotally connected to the first rotating shaft space of the shaft barrel, the first connecting portion is located on one side of the shaft barrel and is connected with the upper cover, and the second rotating shaft is respectively formed with the second side The shaft portion is connected to the second connecting portion, the second shaft portion is pivotally connected to the second rotating shaft space of the shaft barrel, and the second connecting portion is located on one side of the shaft barrel and is connected with the base.
藉上，當上蓋朝向基座底面翻掀時，上蓋會帶動第一轉軸於第一轉軸空間內依上蓋翻掀方向轉動，以及軸筒以第二轉軸為軸心依上蓋翻掀方向轉動，且第一轉軸之轉動方向與第一抵壓部由第一表面之延伸方向相反，降低了二者之間所產生之摩擦阻力， 而軸筒之轉動方向與第二抵壓部由第二表面之延伸方向相反，提高了二者之間所產生之摩擦阻力，俾使第一轉軸之第一軸部與第一抵壓部之間所產生之摩擦阻力小於第二轉軸之第二軸部與第二抵壓部之間所產生之摩擦阻力；反之，當上蓋朝向基座表面翻掀時，上蓋會帶動第一轉軸於第一轉軸空間內依上蓋翻掀方向轉動，以及軸筒以第二轉軸為軸心依上蓋翻掀方向轉動，且第一轉軸之轉動方向與第一抵壓部由第一表面之延伸方向相同，提升了二者之間所產生之摩擦阻力，軸筒之轉動方向與第二抵壓部由第二表面延伸方向相同，降低了二者之間所產生之摩擦阻力，俾使第一轉軸之第一軸部與第一抵壓部之間所產生之摩擦阻力大於第二轉軸之第二軸部與第二抵壓部之間所產生之摩擦阻力。By the way, when the upper cover is turned toward the bottom surface of the base, the upper cover rotates the first rotating shaft in the first rotating shaft space according to the flipping direction of the cover, and the shaft cylinder rotates in the flipping direction of the cover with the second rotating shaft as the axis, and The direction of rotation of the first rotating shaft is opposite to the direction in which the first pressing portion extends from the first surface, which reduces the frictional resistance generated between the two. The rotation direction of the shaft cylinder and the second pressing portion are opposite to the extending direction of the second surface, thereby increasing the frictional resistance generated between the two shafts, so that the first shaft portion of the first rotating shaft and the first pressing portion are The frictional resistance generated between the second shaft portion and the second pressing portion of the second rotating shaft is opposite; when the upper cover is turned toward the surface of the base, the upper cover will drive the first rotating shaft to the first The rotation of the shaft is rotated in the direction of the cover, and the shaft is rotated in the direction of the cover with the second shaft as the axis, and the rotation direction of the first shaft is the same as the direction of extension of the first surface by the first surface. The frictional resistance generated between the two, the direction of rotation of the shaft cylinder and the second pressing portion are the same as the direction in which the second surface extends, reducing the frictional resistance generated between the two, so that the first shaft is first The frictional resistance generated between the shaft portion and the first pressing portion is greater than the frictional resistance generated between the second shaft portion and the second pressing portion of the second rotating shaft.

請參閱第四圖至第十九圖所示，由第四圖至第六圖中可清楚看出，本創作之上蓋8蓋合於基座9表面時，上蓋8係與基座9成平行狀，而轉軸組2之第二定位平面225與軸筒1之第二表面13呈貼合狀，第一定位平面215與第一表面12位於第一轉軸21二相對側，且第一轉軸21之第一限位凸部214抵靠於定位裝置5之第一止擋面514，第二轉軸22之第二限位凸部224抵靠於定位裝置5之第四止擋面517，讓第一轉軸21依軸筒1轉動時，限制轉動範圍於第一止擋面514與第二止擋面515之間，即第一轉軸21之轉動範圍為180度，而軸筒1依第二轉軸22為軸心轉動時，限制轉動範圍於第三止擋面516與第四止擋面517之間，即軸筒1之轉動範圍為180度，且第一轉軸21於轉動時，傳動裝置3之第一限位柱312與第二限位柱322會相互靠近，軸筒1依第二轉軸22為軸心轉動時，第一限位柱312與第二限位柱322會相互遠離；藉此，請同時參閱第四圖至第九圖所示，當使用者將上蓋8朝向 基座9底面翻掀時，由於第一限位柱312抵持於連動件4之第一抵持端411，讓傳動裝置3之第一限位柱312與第二限位柱322無法繼續相互靠近，因此，會由軸筒1依第二轉軸22為軸心轉動，使第二定位平面225脫離第二表面13，解除軸筒1與第二轉軸22之定位狀態，並使第一限位柱312朝向第二抵持端412移動，使第一限位柱312與第二限位柱322之間距離會漸漸加大，請參閱第七圖至第十二圖所示，當第一限位柱312抵持於第一限位孔41之第二抵持端412時，因第一限位柱312與第二限位柱322之間距離無法繼續加大，讓軸筒1無法繼續依第二轉軸22轉動，第一轉軸21於第一轉軸空間15內朝向上蓋8之翻掀方向轉動，而於第二轉軸22轉動時，第一限位柱312與第二限位柱322之間距離會漸漸縮小，讓第一限位柱312朝向第一抵持端411移動，藉此，以限制軸筒1依第二轉軸22為軸心轉動以及第一轉軸21之轉動範圍，請參閱第十二圖至第十五圖所示，由於上蓋8朝向基座9底面翻掀時，第一轉軸21之轉動方向與第一抵壓部14由第一表面12之延伸方向相反，降低了二者之間所產生之摩擦阻力，而軸筒1之轉動方向與第二抵壓部16由第二表面13之延伸方向相反，提高了二者之間所產生之摩擦阻力，俾使第一轉軸21之第一軸部211與第一抵壓部14之間所產生之摩擦阻力小於第二轉軸22之第二軸部221與第二抵壓部16之間所產生之摩擦阻力，也就是讓上蓋8朝向基座9底面翻掀的過程中，不論使用將上蓋8翻掀至任何角度，軸筒1之第二轉軸22轉動之角度皆會超前(大於)第一轉軸21依軸筒1之轉動角度，因此，在上蓋8靠近基座9底面時，定位裝置5之第四止擋面517會先與第二轉軸22之第二限位凸部224形成抵靠限位，即軸筒1依第二轉軸22轉動角度先到達180度，而第一轉軸21依軸筒1轉動之角度，在軸筒1依第二轉軸22轉動 角度到達180度後，才會轉動至180度，也就是說，第一轉軸21之第一定位平面215抵靠於第一表面12，會是在上蓋8朝向基座9底面翻掀360度中最後的行程，讓上蓋8在靠近基座9底面時，會有自動閉合之效果；請參閱第十六圖至第十九圖所示，相反的，當上蓋8朝向基座9表面翻掀時，第一轉軸21之轉動方向與第一抵壓部14由第一表面12之延伸方向相同，提高了二者之間所產生之摩擦阻力，而軸筒1之轉動方向與第二抵壓部16由第二表面13之延伸方向相同，降低了二者之間所產生之摩擦阻力，俾使第一轉軸21之第一軸部211與第一抵壓部14之間所產生之摩擦阻力大於第二轉軸22之第二軸部221與第二抵壓部16之間所產生之摩擦阻力，也就是讓上蓋8朝向基座9表面翻掀的過程中，不論使用將上蓋8翻掀至任何角度，第一轉軸21依軸筒1之轉動角度皆會超前(大於)軸筒1之第二轉軸22轉動之角度，因此，在上蓋8靠近基座9表面時，定位裝置5之第一止擋面514會先與第一轉軸21之第一限位凸部214形成抵靠限位，即第一轉軸21之轉動角度先到達180度，而軸筒1依第二轉軸22轉動之角度，在第一轉軸21轉動角度到達180度後，才會轉動至180度，也就是說，第二轉軸22之第二定位平面225抵靠於第二表面13，會是在上蓋8朝向基座9表面翻掀360度中最後的行程，讓上蓋8在靠近基座9表面時，會有自動閉合之效果。Referring to Figures 4 to 19, it can be clearly seen from the fourth to sixth figures that the upper cover 8 is parallel to the base 9 when the upper cover 8 is covered on the surface of the base 9. The second positioning plane 225 of the rotating shaft set 2 is in abutting shape with the second surface 13 of the shaft barrel 1. The first positioning plane 215 and the first surface 12 are located on opposite sides of the first rotating shaft 21, and the first rotating shaft 21 The first limiting protrusion 214 abuts against the first stopping surface 514 of the positioning device 5 , and the second limiting protrusion 224 of the second rotating shaft 22 abuts against the fourth stopping surface 517 of the positioning device 5 When the rotating shaft 21 rotates according to the shaft cylinder 1, the rotation range is limited between the first stopping surface 514 and the second stopping surface 515, that is, the rotation range of the first rotating shaft 21 is 180 degrees, and the shaft barrel 1 is according to the second rotating shaft. When the axis is rotated, the range of rotation is limited between the third stop surface 516 and the fourth stop surface 517, that is, the rotation range of the barrel 1 is 180 degrees, and the first shaft 21 is rotated, the transmission 3 The first limiting post 312 and the second limiting post 322 are close to each other. When the shaft cylinder 1 is rotated about the second rotating shaft 22, the first limiting post 312 and the second limiting post 322 are far apart from each other. ; Whereby, see FIGS while the fourth to ninth shown in FIG, when the user toward the upper cover 8 When the bottom surface of the base 9 is turned over, the first limiting post 312 and the second limiting post 322 of the transmission 3 cannot continue to each other because the first limiting post 312 abuts against the first abutting end 411 of the linking member 4 . Closely, therefore, the shaft cylinder 1 is rotated about the second rotating shaft 22, so that the second positioning plane 225 is disengaged from the second surface 13, and the positioning state of the shaft cylinder 1 and the second rotating shaft 22 is released, and the first limit is released. The column 312 moves toward the second abutting end 412, so that the distance between the first limiting post 312 and the second limiting post 322 gradually increases, as shown in the seventh to twelfth figures, when the first limit When the positional column 312 is resisted by the second abutting end 412 of the first limiting hole 41, the distance between the first limiting post 312 and the second limiting post 322 cannot continue to increase, so that the shaft can not continue The second rotating shaft 22 rotates, and the first rotating shaft 21 rotates in the turning direction of the upper cover 8 in the first rotating shaft space 15 , and between the first limiting post 312 and the second limiting post 322 when the second rotating shaft 22 rotates. The distance is gradually reduced, and the first limiting post 312 is moved toward the first abutting end 411, thereby restricting the rotation of the shaft barrel 1 about the second rotating shaft 22 and the first For the rotation range of the shaft 21, as shown in the twelfth to fifteenth drawings, since the upper cover 8 is turned toward the bottom surface of the base 9, the rotation direction of the first rotation shaft 21 and the first pressing portion 14 are from the first surface. The extension direction of 12 is reversed, and the frictional resistance generated between the two is reduced, and the rotation direction of the barrel 1 and the second pressing portion 16 are opposite to the direction in which the second surface 13 extends, thereby increasing the occurrence between the two. The frictional resistance causes the frictional resistance generated between the first shaft portion 211 of the first rotating shaft 21 and the first pressing portion 14 to be smaller than between the second shaft portion 221 and the second pressing portion 16 of the second rotating shaft 22 The generated frictional resistance, that is, the process of turning the upper cover 8 toward the bottom surface of the base 9, regardless of the use of the upper cover 8 to any angle, the angle of rotation of the second rotating shaft 22 of the barrel 1 will be advanced (greater than) The first rotating shaft 21 is rotated according to the rotation angle of the shaft cylinder 1. Therefore, when the upper cover 8 is close to the bottom surface of the base 9, the fourth stopping surface 517 of the positioning device 5 is first formed with the second limiting convex portion 224 of the second rotating shaft 22. Abutting the limit, that is, the shaft cylinder 1 reaches 180 degrees according to the rotation angle of the second rotating shaft 22, and the first rotating shaft 21 is guided by the shaft cylinder 1 The angle of rotation, the shaft cylinder 1 rotates according to the second rotating shaft 22 After the angle reaches 180 degrees, it will rotate to 180 degrees, that is, the first positioning plane 215 of the first rotating shaft 21 abuts against the first surface 12, and will be turned 360 degrees in the upper cover 8 toward the bottom surface of the base 9. The final stroke causes the upper cover 8 to have an automatic closing effect when it is near the bottom surface of the base 9; please refer to the sixteenth to nineteenth views, and conversely, when the upper cover 8 is turned toward the surface of the base 9 The rotation direction of the first rotating shaft 21 is the same as the extending direction of the first pressing portion 14 by the first surface 12, which improves the frictional resistance generated between the two, and the rotation direction of the shaft barrel 1 and the second pressing portion The extension direction of the second surface 13 is the same, which reduces the frictional resistance generated between the two, so that the frictional resistance between the first shaft portion 211 of the first rotating shaft 21 and the first pressing portion 14 is greater than The frictional resistance generated between the second shaft portion 221 of the second rotating shaft 22 and the second pressing portion 16, that is, the process of turning the upper cover 8 toward the surface of the base 9, regardless of the use of the upper cover 8 is turned over to any Angle, the first rotating shaft 21 will advance according to the rotation angle of the shaft cylinder 1 (greater than) the second rotating shaft 22 of the shaft cylinder 1 The angle of rotation, therefore, when the upper cover 8 is close to the surface of the base 9, the first stop surface 514 of the positioning device 5 first forms abutting limit with the first limiting protrusion 214 of the first rotating shaft 21, that is, the first The rotation angle of the rotating shaft 21 reaches 180 degrees first, and the shaft cylinder 1 rotates to the angle of 180 degrees after the rotation angle of the first rotating shaft 21 reaches 180 degrees according to the angle of rotation of the second rotating shaft 22, that is, the second rotating shaft 22 The second positioning plane 225 abuts against the second surface 13, which is the last stroke in the upper cover 8 which is turned 360 degrees toward the surface of the base 9, so that the upper cover 8 has an automatic closing effect when it is close to the surface of the base 9. .
