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以及連桿式二種，螺桿式之轉軸裝置，主要是利用第一轉軸與第二轉軸上設置螺紋狀之導槽，並於第一轉軸與第二轉軸之間設置之滑塊，讓滑塊二端之凸塊分別位於導槽內；而連桿式之轉軸裝置，主要是利用連桿樞接於第一轉軸與第二轉軸之側方；然而，不論是螺桿式轉軸裝置或是連桿式轉軸裝置，目前設計者 都忽略一些相當重要的問題，也就是轉軸裝置是設置於電子產品之上蓋與基座之間二側，二轉軸裝置並無相互連動之機構，以及上蓋剛性不足，讓使用者於翻掀上蓋時，產生二轉軸裝置受力不平均；就螺桿式轉軸裝置而言，二轉軸裝置會因受力不平均而造成轉動角度不同，導致上蓋二側與基座之間的角度誤差過大，讓使用者可明顯的看出，且由於第一轉軸、第二轉軸與滑塊為同時作動，因此，一旦二轉軸裝置轉動角度不同，會發生翻掀無法順暢，並造成轉軸裝置磨耗過大，降低使用壽命等問題。 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 two types: a screw type and a connecting rod type, and the screw type rotating shaft device mainly uses a threaded shape on the first rotating shaft and the second rotating shaft. a guide groove, and a slider disposed between the first rotating shaft and the second rotating shaft, wherein the two ends of the sliding block are respectively located in the guiding groove; and the connecting rod type rotating shaft device is mainly connected by the connecting rod a side of the shaft and the second shaft; however, whether it is a screw shaft device or a link shaft device, the current designer Ignore some very important problems, that is, the hinge device is disposed on the two sides between the upper cover of the electronic product and the base, the two shaft devices are not interlocked with each other, and the rigidity of the upper cover is insufficient, so that the user can flip the cover when the cover is turned over. In the case of a screw-type rotating shaft device, the two-axis device may have different rotation angles due to uneven force, resulting in an excessive angular error between the two sides of the upper cover and the base, so that the user It can be clearly seen that, since the first rotating shaft, the second rotating shaft and the slider are simultaneously actuated, once the rotating angle of the two rotating shaft devices is different, the turning can not be smooth, and the rotating shaft device is excessively worn, and the service life is reduced. problem.
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所在。 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.
本發明之主要目的乃在於，利用螺旋導引方式讓轉軸裝置之第一轉軸樞轉以及軸筒繞行第二轉軸轉動交互作用，限制第一轉軸之樞轉角度以及軸筒繞行第二轉軸之轉動角度，以使轉軸裝置可順暢的運作，進而不會產生磨耗過大導致使用壽命降低等情形發生，並可確保電子產品二側之轉軸裝置中，二第一轉軸之樞轉角度誤差，以及二軸筒繞行第二轉軸之轉動角度誤差，保持於一定範圍，而不會產生電子產品上蓋二側與基座之間的角度誤差過大，並使電子產品上蓋與基座展開使用時，上蓋與基座表面可成平行狀，上蓋翻掀至基座底面時，上蓋與基座側邊保持平整，不會有凸出之情形發生。 The main purpose of the present invention is to use the screw guiding method to pivot the first rotating shaft of the rotating shaft device and the rotation of the shaft around the second rotating shaft to limit the pivoting angle of the first rotating shaft and the second rotating shaft of the shaft barrel. The angle of rotation is such that the shaft device can operate smoothly, so that the wear life is not excessively caused, and the service life is reduced, and the pivot angle error of the first shaft can be ensured in the shaft device on both sides of the electronic product, and The rotation angle error of the second shaft around the second shaft is kept within a certain range, and the angle error between the two sides of the upper cover of the electronic product and the base is not excessive, and the upper cover of the electronic product cover and the base is used. The surface of the base can be parallel, and when the upper cover is turned over to the bottom surface of the base, the upper cover and the side of the base are kept flat without protruding.
本發明之次要目的乃在於，利用連桿組進一步限制第一轉軸之樞轉角度以及軸筒繞行第二轉軸之轉動角度，更加提高轉軸裝置之壽命，以及更可確保電子產品上蓋二側與基座之間的角度不會產生誤差過大之情形。 The secondary object of the present invention is to further limit the pivoting angle of the first rotating shaft and the rotation angle of the second rotating shaft of the shaft barrel by using the connecting rod group, thereby further improving the life of the rotating shaft device and ensuring the two sides of the upper cover of the electronic product.

請參閱第一圖與第六圖至第九圖，當使用者翻掀上蓋92遠離基座91時，會施予第一轉軸21樞轉力，以及推動軸筒1依第二轉軸22繞行之偏轉力，如第七圖，當第二凸部35抵持於第二側壁225時，第二凸部35會與第一側壁224產生限位空間227，外力施予第一轉軸21之樞轉力，會因第二凸部35抵持於第二側壁225，讓第一轉軸21之推動槽213無法推動第一凸部34，而使 第一轉軸21帶動位移滑塊3與軸筒1繞行第二轉軸22，使第二凸部35依據限位槽223移動，進而朝向第一側壁224靠近，並抵靠於於第一側壁224，使第二凸部35與第二側壁225之間間隔產生位移空間226，此時，由於第二凸部35受到第一側壁224之止擋，讓第一轉軸21無法繼續帶動位移滑塊3與軸筒1繞行第二轉軸22，因此，外力施予第一轉軸21之樞轉力即會使第一轉軸21樞轉，讓第一轉軸21之推動槽213推動第一凸部34，使位移滑塊3朝向第二側壁225之方向位移，並抵靠於第二側壁225，使第二凸部35會與第一側壁224產生限位空間227，重複上述動作，即會使第一轉軸21樞轉以及軸筒1與位移滑塊3繞行第二轉軸22轉動交互作用，進而可限制第一轉軸21之樞轉角度以及軸筒1與位移滑塊3繞行第二轉軸22之轉動角度，進而確保電子產品9二側之轉軸裝置10中，二第一轉軸21之樞轉角度誤差，以及二軸筒1繞行第二轉軸22之轉動角度誤差，保持於一定範圍，而不會產生上蓋92二側與基座91之間的角度誤差過大，並可使轉軸裝置10順利轉動，不會因誤差過大而增加磨耗。再者，如第九圖所示，由於第一轉軸21以固定角度樞轉後，軸筒1與位移滑塊3再繞行第二轉軸22一定角度，藉由二者交互作動，讓上蓋92翻掀至與基座91平行時，軸筒1亦會與上蓋92及基座91表面成平行狀，讓使用者可將電子產品9平放於桌面使用，而不會有上蓋92或基座91無法平貼於桌面之情形發生，且於上蓋92翻掀至與基座91底面時，軸筒1與上蓋92及基座91會成垂直狀，使上蓋92與基座91邊緣呈平整狀，而不會有較為凸出之側邊。 Referring to the first figure and the sixth figure to the ninth figure, when the user flips the upper cover 92 away from the base 91, the pivoting force of the first rotating shaft 21 is applied, and the shaft barrel 1 is pushed around the second rotating shaft 22. The deflection force, as shown in the seventh figure, when the second convex portion 35 abuts against the second side wall 225, the second convex portion 35 generates a limiting space 227 with the first side wall 224, and the external force is applied to the pivot of the first rotating shaft 21 The rotation force causes the second convex portion 35 to abut against the second side wall 225, so that the pushing groove 213 of the first rotating shaft 21 cannot push the first convex portion 34, thereby The first rotating shaft 21 drives the displacement slider 3 and the shaft barrel 1 to bypass the second rotating shaft 22 , so that the second convex portion 35 moves according to the limiting slot 223 , and then approaches the first sidewall 224 and abuts against the first sidewall 224 . The displacement between the second convex portion 35 and the second side wall 225 is caused by the displacement space 226. At this time, since the second convex portion 35 is blocked by the first side wall 224, the first rotating shaft 21 cannot continue to drive the displacement slider 3 . The second rotating shaft 22 is wound around the shaft tube 1. Therefore, the pivoting force applied by the external force to the first rotating shaft 21 causes the first rotating shaft 21 to pivot, and the pushing groove 213 of the first rotating shaft 21 pushes the first convex portion 34, Displace the displacement slider 3 toward the second sidewall 225 and abut against the second sidewall 225, so that the second protrusion 35 and the first sidewall 224 generate a limiting space 227, and the above action is repeated, that is, the first The rotation of the rotating shaft 21 and the rotation of the shaft barrel 1 and the displacement slider 3 around the second rotating shaft 22 can further limit the pivoting angle of the first rotating shaft 21 and the winding of the shaft barrel 1 and the displacement slider 3 around the second rotating shaft 22 The rotation angle ensures the pivoting angle error of the two first rotating shafts 21 in the rotating shaft device 10 on both sides of the electronic product 9, And the rotation angle error of the second shaft 2 around the second rotating shaft 22 is maintained within a certain range without causing an excessive angular error between the two sides of the upper cover 92 and the base 91, and the rotating shaft device 10 can be smoothly rotated, It will increase wear due to excessive error. Furthermore, as shown in the ninth figure, since the first rotating shaft 21 is pivoted at a fixed angle, the shaft barrel 1 and the displacement slider 3 are further rotated around the second rotating shaft 22 by an angle, and the upper cover 92 is operated by interaction between the two. When it is turned into parallel with the base 91, the barrel 1 is also parallel with the surfaces of the upper cover 92 and the base 91, so that the user can use the electronic product 9 on the table without the upper cover 92 or the base. 91 can not be flat on the table top, and when the upper cover 92 is turned over to the bottom surface of the base 91, the barrel 1 and the upper cover 92 and the base 91 are perpendicular, so that the upper cover 92 and the edge of the base 91 are flat. Without a more convex side.
請參閱第一圖與第六圖至第十一圖所示，第一轉軸21樞轉時，會帶動第一轉動件41樞轉，讓第一限位柱412與第二限位 柱422之間距離漸大，第一轉軸21繞行第二轉軸22時讓第一限位柱412與第二限位柱422之間距離漸小，而於第二凸部35抵持於第二側壁225時，第二凸部35會與第一側壁224產生限位空間227，連桿組4之第一限位柱412會抵持於第一抵持端4311，外力施予第一轉軸21之樞轉力，會因第二凸部35抵持於第二側壁225，讓第一轉軸21之推動槽213無法推動第一凸部34，以及第一限位柱412受到第一抵持端4311之止擋，而無法靠近第二限位柱422，俾使第一轉軸21無法轉動，進而使第一轉軸21帶動軸筒1與位移滑塊3繞行第二轉軸22，讓第二凸部35朝向第一側壁224靠近，且第一轉軸21會帶動第一轉動件41繞行第二轉軸22，使第一限位柱412與第二限位柱422之間距離加大，讓第一限位柱412朝向第二抵持端4312位移，並抵持於第二抵持端4312，而於第二凸部35受到第一側壁224之止擋時，第一限位柱412也會同時的抵持於第二抵持端4312，讓第一轉軸21無法繼續帶動位移滑塊3與軸筒1繞行第二轉軸22，因此，外力施予第一轉軸21之樞轉力即會使第一轉軸21樞轉，讓第一轉軸21之推動槽213推動第一凸部34，使位移滑塊3朝向第二側壁225之方向位移，並抵靠於第二側壁225，使第二凸部35會與第一側壁224產生限位空間227，以及第一轉軸21帶動第一轉動件41樞轉，使第一限位柱412與第二限位柱422之間距離漸大，讓第一限位柱412抵持於第一抵持端4311，重複上述動作，即會使第一轉軸21樞轉以及軸筒1與位移滑塊3繞行第二轉軸22轉動交互作用，藉由連桿組4之設置，即使推動槽213或限位槽223因磨耗產生誤差時，連桿組4亦可準確的限制第一轉軸21之樞轉角度以及軸筒1與位移滑塊3繞行第二轉軸22之轉動角度，進而確保電子產品9二側之轉軸裝置10中，二第一轉軸21之樞轉角度誤差， 以及二軸筒1繞行第二轉軸22之轉動角度誤差，保持於一定範圍，而不會產生上蓋92二側與基座91之間的角度誤差過大。 Referring to the first figure and the sixth figure to the eleventh figure, when the first rotating shaft 21 is pivoted, the first rotating member 41 is pivoted to allow the first limiting post 412 and the second limiting position. The distance between the pillars 422 is gradually increased. When the first rotating shaft 21 bypasses the second rotating shaft 22, the distance between the first limiting pillar 412 and the second limiting pillar 422 is gradually decreased, and the second convex portion 35 is resisted by the second convex portion 35. When the two side walls 225 are formed, the second convex portion 35 generates a limiting space 227 with the first side wall 224. The first limiting post 412 of the connecting rod set 4 abuts against the first abutting end 4311, and the external force is applied to the first rotating shaft. The pivoting force of 21 causes the second protrusion 35 to abut against the second side wall 225, so that the pushing groove 213 of the first rotating shaft 21 cannot push the first convex portion 34, and the first limiting post 412 is firstly resisted. The stop of the end 4311 is not close to the second limit post 422, so that the first rotating shaft 21 cannot be rotated, so that the first rotating shaft 21 drives the shaft barrel 1 and the displacement slider 3 to bypass the second rotating shaft 22, so that the second The convex portion 35 is adjacent to the first side wall 224, and the first rotating shaft 21 drives the first rotating member 41 to bypass the second rotating shaft 22, so that the distance between the first limiting post 412 and the second limiting post 422 is increased. The first limiting post 412 is displaced toward the second abutting end 4312 and abuts against the second abutting end 4312. When the second convex portion 35 is blocked by the first sidewall 224, the first limiting post 412 is also Simultaneously resisting the second abutting end 4312, the first rotating shaft 21 cannot continue to drive the displacement slider 3 and the barrel 1 to bypass the second rotating shaft 22. Therefore, the pivoting force of the external force applied to the first rotating shaft 21 is The first rotating shaft 21 is pivoted, and the pushing groove 213 of the first rotating shaft 21 pushes the first convex portion 34 to displace the displacement slider 3 toward the second side wall 225, and abuts against the second side wall 225, so that the second The convex portion 35 generates a limiting space 227 with the first side wall 224, and the first rotating shaft 21 drives the first rotating member 41 to pivot, so that the distance between the first limiting post 412 and the second limiting post 422 is gradually increased. The first limiting post 412 is abutted against the first abutting end 4311, and the above action is repeated, that is, the first rotating shaft 21 is pivoted and the shaft cylinder 1 and the displacement sliding block 3 are rotated and rotated around the second rotating shaft 22, by The setting of the connecting rod set 4 can accurately limit the pivoting angle of the first rotating shaft 21 and the winding of the shaft barrel 1 and the displacement slider 3 even if the pushing groove 213 or the limiting groove 223 generate an error due to wear.
