按，生活中有許多物品都使用到轉軸裝置，如筆記型電腦、電子字典、個人數位化電子秘書(PDA)及雙頁式電子產品等，都必須借助轉軸裝置連接物品之基座與上蓋達到掀翻開關之功用。Press, there are many items in life that use the hinge device, such as notebook computer, electronic dictionary, personal digital electronic secretary (PDA) and double-page electronic products, etc., must be connected to the base and top cover of the article by means of the hinge device. The function of flipping the switch.
請參閱第五圖及第六圖所示，由圖中可清楚得知，習知技術所使用之轉軸裝置9設置有軸筒91以及轉軸92，而軸筒91為具有基部911，且基部911一側延伸抵持部912，抵持部912末端彎折有抵壓部913，而轉軸92外緣設置有平面狀之定位面921，俾使轉軸92因受到抵壓部913之抵壓，讓定位面921正對於基部911時形成定位，如第六圖所示，當轉軸92於旋動使基部911與定位面921脫離定位時，轉軸92為會推動抵壓部913朝向遠離基部911之方向位移，此時抵壓部913因位移所產生之應力會集中於抵持部912與抵壓部913之連接處，但由於抵持部912與抵壓部913之連接處為抵靠於轉軸92外緣，因此無法產生位移來吸收應力，造成應力無法釋放，而於長時間的使用轉軸裝置9時，容易造成抵持部912與抵壓部913之連接處產生斷裂。Referring to the fifth and sixth figures, it can be clearly seen from the figure that the shaft device 9 used in the prior art is provided with a shaft cylinder 91 and a rotating shaft 92, and the shaft cylinder 91 has a base portion 911, and the base portion 911 One end of the abutting portion 912 extends, and the end portion of the abutting portion 912 is bent with a pressing portion 913, and the outer edge of the rotating shaft 92 is provided with a planar positioning surface 921, so that the rotating shaft 92 is pressed by the pressing portion 913, so that When the positioning surface 921 is positioned with respect to the base portion 911, as shown in the sixth figure, when the rotating shaft 92 is rotated to position the base portion 911 and the positioning surface 921, the rotating shaft 92 is directed to push the pressing portion 913 toward the direction away from the base portion 911. At this time, the stress generated by the displacement of the pressing portion 913 is concentrated on the joint between the abutting portion 912 and the pressing portion 913, but the joint between the abutting portion 912 and the pressing portion 913 is abutted against the rotating shaft 92. Since the outer edge is not displaced to absorb the stress, the stress cannot be released, and when the shaft device 9 is used for a long time, the joint between the abutting portion 912 and the pressing portion 913 is liable to be broken.

請參閱第一圖所示以及第二圖所示，由圖中可清楚看出，本發明之轉軸10係設置有軸桿1以及軸筒2，其中：該軸桿1外緣係形成有圓弧狀之摩擦面11，摩擦面11一側 形成有平面狀之定位面12，軸桿1之軸心13到摩擦面11之半徑為大於軸心13到定位面12之半徑。Referring to the first figure and the second figure, it can be clearly seen from the figure that the rotating shaft 10 of the present invention is provided with a shaft 1 and a shaft barrel 2, wherein: the outer edge of the shaft 1 is formed with a circle Arc-shaped friction surface 11, friction surface 11 side A planar positioning surface 12 is formed, and the radius from the axis 13 of the shaft 1 to the friction surface 11 is greater than the radius of the axis 13 to the positioning surface 12.
該軸筒2係設置有平板狀之基部21，基部21一端彎折延伸有第一彈性段22以及抵壓段23，且抵壓段23末端與基部21遠離第一彈性段22之另端形成有缺槽24。The shaft barrel 2 is provided with a flat base portion 21. One end of the base portion 21 is bent and extended with a first elastic portion 22 and a pressing portion 23, and the end of the pressing portion 23 and the base portion 21 are formed away from the other end of the first elastic portion 22. There is a missing slot 24.
藉上，當本發明於組構時，係將軸桿1穿設於軸筒2內，使軸筒2為包覆於軸桿1外緣，並讓軸筒2之基部21為位於軸桿1下方側，並正對於軸桿1之定位面12，而軸筒2之抵壓段23為位於軸桿1遠離基部21之另側；再者，軸筒2之抵壓段23為抵持於軸桿1，第一彈性段22係呈圓弧狀，且第一彈性段22之弧度為小於軸桿1之摩擦面11弧度，俾使第一彈性段22與摩擦面11間隔出彈性變形空間3。By the way, when the invention is in the configuration, the shaft 1 is inserted into the shaft barrel 2, so that the shaft barrel 2 is wrapped around the outer edge of the shaft 1, and the base 21 of the shaft barrel 2 is located on the shaft. 1 lower side, and is facing the positioning surface 12 of the shaft 1, and the pressing portion 23 of the shaft barrel 2 is located on the other side of the shaft 1 away from the base portion 21; further, the pressing portion 23 of the shaft barrel 2 is resisted In the shaft 1, the first elastic segment 22 is arc-shaped, and the curvature of the first elastic segment 22 is smaller than the friction surface 11 of the shaft 1, so that the first elastic segment 22 and the friction surface 11 are elastically deformed. Space 3.
當軸桿1旋開時(旋動方向如第二圖圖中實心箭號所示)，軸桿1之轉動會使定位面12與軸筒2之基部21脫離定位狀態，由於軸桿1之軸心13到摩擦面11之半徑為大於軸心13到定位面12之半徑，因此，當定位面12與基部21脫離定位狀態時，軸桿1為會推動軸筒2之抵壓段23，使抵壓段23朝向遠離基部21之方向產生位移，由於軸筒2之第一彈性段22與摩擦面11間隔有彈性變形空間3，因此，當軸桿1推動抵壓段23位移時，抵壓段23因位移所產生之應力會由第一彈性段22朝向軸桿1位移所吸收，且由於第一彈性段22呈圓弧狀，更可將所吸收之應力較為平均的分攤至整個第一彈性段22，使第一彈性段22以彈性變形吸收抵壓段23因位移所產生之應力，以防止應力過於集中一處而造成斷裂。When the shaft 1 is unscrewed (the direction of rotation is as indicated by the solid arrow in the second figure), the rotation of the shaft 1 causes the positioning surface 12 to be disengaged from the base 21 of the barrel 2, due to the shaft 1 The radius of the axial center 13 to the friction surface 11 is greater than the radius of the axial center 13 to the positioning surface 12. Therefore, when the positioning surface 12 and the base portion 21 are disengaged from the positioning state, the shaft 1 is a pressing portion 23 that pushes the shaft barrel 2, Displacement of the pressing portion 23 away from the base portion 21, since the first elastic portion 22 of the barrel 2 is spaced apart from the friction surface 11 by the elastic deformation space 3, when the shaft 1 is pushed against the pressing portion 23, The stress generated by the displacement of the pressure section 23 is absorbed by the displacement of the first elastic section 22 toward the shaft 1, and since the first elastic section 22 has an arc shape, the absorbed stress can be evenly distributed to the whole section. An elastic section 22 causes the first elastic section 22 to absorb the stress generated by the displacement of the pressing section 23 by elastic deformation to prevent the stress from being concentrated too much and causing the fracture.
請參閱第三圖以及第四圖所示，由圖中可清楚看出，本發明之轉軸10係設置有軸桿4以及軸筒5，其中： 該軸桿4外緣係形成有圓弧狀之摩擦面41，摩擦面41一側形成有平面狀之定位面42，軸桿4之軸心43到摩擦面41之半徑為大於軸心43到定位面42之半徑。Referring to the third and fourth figures, it can be clearly seen from the figure that the rotating shaft 10 of the present invention is provided with a shaft 4 and a shaft barrel 5, wherein: The outer edge of the shaft 4 is formed with an arc-shaped friction surface 41, and a side of the friction surface 41 is formed with a planar positioning surface 42. The radius of the shaft 43 of the shaft 4 to the friction surface 41 is larger than the axis 43 to The radius of the positioning surface 42.
該軸筒5係設置有平板狀之基部51，基部51一端連續彎折延伸有第一彈性段52、抵靠段53、第二彈性段54及抵壓段55，且抵壓段55末端與基部51遠離第一彈性段52之另端形成缺槽56。The shaft barrel 5 is provided with a flat base portion 51. One end of the base portion 51 is continuously bent and extended with a first elastic portion 52, an abutting portion 53, a second elastic portion 54 and a pressing portion 55, and the end of the pressing portion 55 is The base 51 is spaced away from the other end of the first elastic section 52 to form a notch 56.
藉上，當本發明於組構時，係將軸桿4穿設於軸筒5內，使軸筒5為包覆於軸桿4外緣，讓軸筒5之基部51與第一彈性段52為位於軸桿4下方側，且基部51正對於軸桿4之定位面42，而軸筒5之第二彈性段54以及抵壓段55為位於軸桿4遠離基部51與第一彈性段52之另側，使第二彈性段54以及抵壓段55位於軸桿4上方側；再者，軸筒5之基部51、抵靠段53以及抵壓段55為抵持於軸桿4，而第一彈性段52以及第二彈性段54係呈圓弧狀，且第一彈性段52與第二彈性段54之弧度為小於軸桿4之摩擦面41弧度，俾使第一彈性段52以及第二彈性段54分別與摩擦面41間隔出第一彈性變形空間6以及第二彈性變形空間7。Therefore, when the present invention is configured, the shaft 4 is inserted into the shaft barrel 5 such that the shaft barrel 5 is wrapped around the outer edge of the shaft 4, and the base portion 51 of the shaft barrel 5 and the first elastic portion are used. 52 is located on the lower side of the shaft 4, and the base portion 51 is opposite to the positioning surface 42 of the shaft 4, and the second elastic portion 54 of the barrel 5 and the pressing portion 55 are located at the shaft 4 away from the base portion 51 and the first elastic portion. The other side of the 52, the second elastic section 54 and the pressing section 55 are located on the upper side of the shaft 4; further, the base 51, the abutting section 53 and the pressing section 55 of the barrel 5 are abutted against the shaft 4, The first elastic segment 52 and the second elastic segment 54 are arcuate, and the arc of the first elastic segment 52 and the second elastic segment 54 is smaller than the arc of the friction surface 41 of the shaft 4, so that the first elastic segment 52 is 52. The second elastic segments 54 are spaced apart from the friction surface 41 by the first elastic deformation space 6 and the second elastic deformation space 7, respectively.
當軸桿4旋開時(旋動方向如第四圖圖中實心箭號所示)，軸桿4之轉動會使定位面42與軸筒5之基部51脫離定位狀態，由於軸桿4之軸心43到摩擦面41之半徑為大於軸心43到定位面42之半徑，因此，當定位面42與基部51脫離定位狀態時，軸桿4為會推動軸筒5之抵壓段55，使抵壓段55朝向遠離基部51之方向產生位移，而抵壓段55因位移所產生之應力會先由第二彈性段54朝向軸桿4位移所吸收；再者，抵壓段55於位移時所產生之抵持力會作用於軸桿4，使軸桿4朝向抵靠段53推擠，而第 二彈性段54於朝向軸桿4位移時所產生之應力亦會作用於抵靠段53，使抵靠段53略為產生偏移，進而讓第一彈性段52朝向軸桿4位移吸收抵靠段53因偏移所產生之應力；又，該第一彈性段52以及第二彈性段54為呈圓弧狀，因此，可將所吸收之應力較為平均的分攤，使第一彈性段52與第二彈性段54以彈性變形吸收因位移所產生之應力，以防止應力過於集中而造成斷裂。When the shaft 4 is unscrewed (the direction of rotation is as indicated by the solid arrow in the fourth figure), the rotation of the shaft 4 causes the positioning surface 42 to be disengaged from the base 51 of the barrel 5 due to the shaft 4 The radius of the axial center 43 to the friction surface 41 is greater than the radius of the axial center 43 to the positioning surface 42. Therefore, when the positioning surface 42 is separated from the base portion 51, the shaft 4 is a pressing portion 55 that pushes the shaft barrel 5, The pressing portion 55 is displaced in a direction away from the base portion 51, and the stress generated by the displacement of the pressing portion 55 is first absorbed by the displacement of the second elastic portion 54 toward the shaft 4; further, the pressing portion 55 is displaced. The force generated during the action will act on the shaft 4, causing the shaft 4 to push toward the abutment section 53, and The stress generated when the two elastic segments 54 are displaced toward the shaft 4 also acts on the abutting portion 53, causing the abutting portion 53 to slightly shift, thereby causing the first elastic portion 52 to be displaced toward the shaft 4 to absorb the abutting portion. The stress caused by the offset; in addition, the first elastic segment 52 and the second elastic segment 54 are arc-shaped, so that the absorbed stress can be evenly distributed, so that the first elastic segment 52 and the first elastic segment 52 The two elastic segments 54 absorb the stress caused by the displacement by elastic deformation to prevent the stress from being excessively concentrated and causing the fracture.
