In this embodiment, the upper fixed frame 31 and the lower fixed frame 32 are respectively coupled to the first mandrel 10 and the second The shaft of the mandrel 20 is riveted and fixed at one end.
所述動力區40則於所述第一心軸10及第二心軸20的桿身上分別設有可彼此嚙接的非同向左旋及右旋螺旋齒輪41、42，於此一實施例中，所述非同向左旋及右旋螺旋齒輪41、42結構分別由所述第一心軸10及第二心軸20的桿身一體成型，所述彼此嚙接的非同向左旋及右旋螺旋齒輪41、42為非同向的左右旋齒輪，舉例而言，例如其中之一齒輪為左旋齒輪，另一齒輪則為右旋齒輪，且在較佳實施例中，上述左旋及右旋角度最好各為45度角，以降低轉動運作時所承受的轉動應力。 The power zone 40 is respectively provided with non-codirectional left-handed and right-handed helical gears 41 and 42 that are engageable with each other on the rods of the first mandrel 10 and the second mandrel 20, in this embodiment. The non-codirectional left-handed and right-handed helical gears 41, 42 are integrally formed by the shafts of the first mandrel 10 and the second mandrel 20, respectively, and the non-co-rotating left-handed and right-handed mutually engaged The helical gears 41, 42 are non-codirectional left and right rotating gears, for example, one of which is a left-handed gear and the other of which is a right-handed gear, and in the preferred embodiment, the left-handed and right-handed angles Preferably, each angle is 45 degrees to reduce the rotational stress experienced during the rotation operation.
所述扭力區50於此一實施例中，包括活動穿過所述第一心軸10及第二心軸20的多數個定位承架51、與所述第一心軸10及第二心軸20組接連動的多數個墊片52及活動穿過所述第一心軸10及第二心軸20的多數個如皿型彈簧之類扭力彈片53彼此併合排列構成該扭力區50，然後由所述第一心軸10及第二心軸20的另一端部以如螺帽或扣環之類固定元件60鎖接定位整個樞軸器。 The torque zone 50 includes a plurality of positioning brackets 51 that move through the first mandrel 10 and the second mandrel 20, and the first mandrel 10 and the second mandrel, in this embodiment. 20 sets of consecutive spacers 52 and a plurality of torsion springs 53 moving through the first mandrel 10 and the second mandrel 20, such as a cup spring, are arranged side by side to form the torsion zone 50, and then The other ends of the first mandrel 10 and the second mandrel 20 are locked by a fixing member 60 such as a nut or a buckle to position the entire pivot.
如第3至5圖所示，本創作由於在所述動力區40使用非同向左旋及右旋螺旋齒輪41、42，因此，所述第一心軸10及第二心軸20因電子設備的顯示螢幕上蓋或主機系統端進行開閉動作時而產生旋轉動作，使非同向左旋及右旋螺旋齒輪41、42的任一齒輪轉動時，另一齒輪即隨之反向旋轉，形成樞軸器的雙軸同動功能。由於使用具有較小縱向總合高度的非同向左旋及右旋螺旋齒輪41、42，整個樞軸器因而可有效的加以薄型化。 As shown in FIGS. 3 to 5, the present invention uses the non-codirectional left-handed and right-handed helical gears 41, 42 in the power zone 40, so that the first mandrel 10 and the second mandrel 20 are electronic devices. When the screen cover or the main system end is opened and closed, a rotation operation is generated, and when any of the non-codirectional left-handed and right-hand helical gears 41 and 42 is rotated, the other gear is reversely rotated to form a pivot. The dual axis synchronization function. Since the non-codirectional left-handed and right-handed helical gears 41, 42 having a small longitudinal total height are used, the entire pivot can be effectively thinned.
於第6圖所示本創作第二實施例中，所述扭力區50A由多數個扭力件501並排成所需的扭力堆疊結構，所述扭力件501設有上穿孔502及下穿孔503供分別活動穿過所述第一心軸10及第二心軸20，所述上穿孔502及下穿孔503分別設有朝外開放的扭力缺口504、505。 In the second embodiment of the present invention shown in FIG. 6, the torsion zone 50A is arranged side by side by a plurality of torsion members 501 into a desired torque stacking structure. The torsion member 501 is provided with an upper perforation 502 and a lower perforation 503. The first mandrel 10 and the second mandrel 20 are respectively moved, and the upper perforation 502 and the lower perforation 503 are respectively provided with torsion notches 504 and 505 which are open outward.
於第7圖及7A圖所示本創作第三實施例中，所述扭力區50B由多數個定位扭力件506反向並排成所需的扭力結構，所述定位扭力件506於一側邊具有兩相對直平折邊507、508，並於所述兩相對直平折邊507、508端部之間形成所需的定位扭力缺口509；由於在此一薄型化樞軸器結構中空間較小，所述兩相對直平折邊507、508可配合兩相對心軸用以連動組合的上下相對削平面，以替代凸輪之類構件形成自動定位功能。同時，由此一實施例中亦可看出，所述上固定承架310及下固定承架320能以捲包結構311、321分別與心軸一端固定組接，供方便在薄型化的較小空間中取代如上述的鉚接固定結構。 In the third embodiment of the present invention shown in FIGS. 7 and 7A, the torsion zone 50B is reversely aligned by a plurality of positioning torsion members 506 into a desired torsion structure, and the positioning torsion member 506 is on one side. Having two opposing straight flanges 507, 508 and forming a desired positioning torque gap 509 between the ends of the two opposite straight flanges 507, 508; due to the space in a thinner pivot structure Small, the two opposite straight flanges 507, 508 can cooperate with two opposite mandrels for interlocking the upper and lower opposite cutting planes to form an automatic positioning function instead of a cam or the like. At the same time, it can also be seen that the upper fixed frame 310 and the lower fixed frame 320 can be fixedly assembled with one end of the mandrel in the package structure 311, 321 for convenient thinning. The riveted fixing structure as described above is replaced in a small space.
本創作因而形成一種雙軸樞軸器改良設計，由於經由兩非同向的左旋及右旋螺旋齒輪進行雙軸同動以取代現有的正齒輪嚙接傳動機構，能有效縮短整個樞軸器的縱向高度，使此類雙軸樞軸器能適用於薄型化的電子產品上；同時，整個雙軸同動樞軸器在運作時亦能有效降低所承受的轉動應力。 The creation thus forms an improved design of the two-axis pivot, which can effectively shorten the entire pivot by replacing the existing spur gear transmission mechanism by two-axis co-rotation through two non-codirectional left-hand and right-hand helical gears. The longitudinal height makes this type of biaxial pivot suitable for thin electronic products. At the same time, the entire two-axis articulated pivot can effectively reduce the rotational stress it is subjected to during operation.
