Description
本創作係有關於一種樞軸總成，且特別是有關於一種循序鎖定式樞軸總成。
This creation is related to a pivot assembly and, in particular, to a sequential locking pivot assembly.
隨著觸控螢幕技術日趨成熟，除了平板電腦與智慧型手機以外，筆記型電腦也開始配置觸控螢幕，此種配置有觸控螢幕的筆記型電腦可兼具平板電腦的功能，其包括有第一板體與第二板體。第一板體例如是安裝有觸控螢幕的上蓋，第二板體例如是安裝有電腦零組件、電池與鍵盤的底座。為了讓所述筆記型電腦可以當作平板電腦操作，需要將其設置為第一板體的螢幕朝外，並且第一板體與第二板體彼此合攏貼齊的狀態。為了達到此種狀態，第一板體與第二板體之間的連接關係可採用以下幾種方式。With the maturity of touch screen technology, in addition to tablet computers and smart phones, notebook computers have also begun to configure touch screens. This type of notebook with touch screen can combine the functions of a tablet computer, including The first plate body and the second plate body. The first board is, for example, an upper cover on which a touch screen is mounted, and the second board is, for example, a base on which computer components, a battery, and a keyboard are mounted. In order to allow the notebook computer to operate as a tablet computer, it is required to set the screen of the first board body outward, and the first board body and the second board body are close to each other. In order to achieve such a state, the connection relationship between the first plate body and the second plate body may be in the following manners.
第一種方式係在第一板體的一側邊的中央處裝設有第一樞接部，在第二板體的一側邊的中央處裝設有對應所述第一樞接部的第二樞接部，藉由第一樞接部與第二樞接部互相連接且具有旋轉與翻轉的自由度，使第一板體與第二板體可進行相對旋轉與翻轉運動，如此一來，即可因應不同需求改變第二板體相對於第一板體的夾角角度。並且，可將第一板體相對於第二板體旋轉180度後再翻轉以致與第二板體合攏貼齊，並使第一板體的螢幕朝外。如此一來，此筆記型電腦會形成如同平板電腦般的狀態，便於使用者觸控操作或手持使用。然而，上述樞接結構屬於單點支撐，因此結構強度較弱，長久使用後，恐有斷裂之虞。In the first method, a first pivoting portion is disposed at a center of one side of the first plate body, and a center corresponding to the first pivoting portion is disposed at a center of one side of the second plate body. The second pivoting portion is connected to the second pivoting portion by the first pivoting portion and has a degree of freedom of rotation and reversal, so that the first plate body and the second plate body can be relatively rotated and reversed. In order to change the angle between the second plate and the first plate according to different requirements. Moreover, the first plate body can be rotated 180 degrees with respect to the second plate body and then turned over so as to be closed and aligned with the second plate body, and the screen of the first plate body faces outward. In this way, the notebook computer will form a tablet-like state, which is convenient for the user to touch or use. However, the above-mentioned pivotal structure belongs to a single point support, so the structural strength is weak, and after a long period of use, there is a fear of breakage.
第二種方式係在第一板體與第二板體的同側邊設置雙軸式樞軸總成，雙軸式樞軸總成具有第一軸與第二軸，且第一軸與第二軸分別連接第一板體與第二板體，如此第一板體與第二板體可在0度至360度之間相對翻轉，當第一板體與第二板體相對翻轉至360度時，第一板體與第二板體系合攏貼齊且第一板體的螢幕朝外。然後，此種雙軸式樞軸總成，經常有第一軸與第二軸在旋轉時，因作動順序不一致而產生操作不便與旋轉不順的情況。The second method is to provide a two-axis pivot assembly on the same side of the first plate body and the second plate body, the two-axis pivot assembly has a first axis and a second axis, and the first axis and the first axis The two shafts are respectively connected to the first plate body and the second plate body, such that the first plate body and the second plate body are relatively reversed between 0 degrees and 360 degrees, when the first plate body and the second plate body are oppositely turned to 360. When the degree is small, the first plate body and the second plate system are close together and the screen of the first plate body faces outward. Then, such a biaxial pivot assembly often has a case where the first axis and the second axis rotate, and the operation sequence is inconsistent, resulting in inconvenience in operation and unsatisfactory rotation.

請再同時參照第2圖與第3圖，第2圖為循序鎖定式樞軸總成13的***圖，第3圖為循序鎖定式樞軸總成13於另一視角的組立圖。循序鎖定式樞軸總成13包括支承部20、第一軸30、第二軸40、第一環體50、第二環體60、第三環體70、主齒輪81與副齒輪82。支承部20包括第一支承板21與第二支承板22，第一支承板21與第二支承板22彼此間隔設置且互相平行，第一支承板21與第二支承板22上分別設置有複數軸孔（未標號）。支承部20還具有第一止擋件23與第二止擋件24，如第3圖所示，在本實施例中，第一止擋件23與第二止擋件24實質上為凸設於第一支承板21背離第二支承板22的表面上的凸塊。Please refer to FIG. 2 and FIG. 3 at the same time. FIG. 2 is an exploded view of the sequential locking pivot assembly 13, and FIG. 3 is an assembled view of the sequential locking pivot assembly 13 at another viewing angle. The sequential locking pivot assembly 13 includes a support portion 20, a first shaft 30, a second shaft 40, a first ring body 50, a second ring body 60, a third ring body 70, a main gear 81, and a pinion gear 82. The support portion 20 includes a first support plate 21 and a second support plate 22, and the first support plate 21 and the second support plate 22 are spaced apart from each other and parallel to each other, and the first support plate 21 and the second support plate 22 are respectively provided with a plurality of Shaft hole (not labeled). The support portion 20 further has a first stopper 23 and a second stopper 24. As shown in FIG. 3, in the embodiment, the first stopper 23 and the second stopper 24 are substantially convex. A bump on the surface of the first support plate 21 facing away from the second support plate 22.
第一軸30與第二軸40分別樞接支承部20，亦即，第一軸30與第二軸40分別可旋轉地穿設於第一支承板21與第二支承板22上的相應軸孔中，並且，第一軸30與第二軸40互相平行。如第3圖所示，第一軸30具有第一限位件31，第一限位件31對應於第一止擋件23設置，第二軸40具有第二限位件41，第二限位件41對應於第二止擋件24設置。在本實施例中，第一限位件31實質上為徑向凸設於第一軸30的凸緣，第二限位件41實質上為徑向凸設於第二軸40的凸緣。第一限位件31與第二限位件41分別與第一軸30與第二軸40連動旋轉，且第一限位件31與第二限位件41的兩端分別與第一軸30與第二軸40形成段差，第一止擋件23位於第一限位件31的移動路徑上，因此第一止擋件23可選擇性地止擋於第一限位件31的兩端之一，藉此限制第一軸30的旋轉方向與角度；第二止擋件24位於第二限位件41的移動路徑上，因此第二止擋件24可選擇性地止擋於第二限位件41的兩端之一，藉此限制第二軸40的旋轉方向與角度。The first shaft 30 and the second shaft 40 are respectively pivotally connected to the support portion 20, that is, the first shaft 30 and the second shaft 40 are rotatably respectively disposed on the corresponding shafts of the first support plate 21 and the second support plate 22. In the hole, and the first shaft 30 and the second shaft 40 are parallel to each other. As shown in FIG. 3, the first shaft 30 has a first limiting member 31, the first limiting member 31 is disposed corresponding to the first stopping member 23, and the second shaft 40 has a second limiting member 41. The bit member 41 is disposed corresponding to the second stopper 24. In the present embodiment, the first limiting member 31 is substantially a flange protruding radially from the first shaft 30, and the second limiting member 41 is substantially a flange protruding radially from the second shaft 40. The first limiting member 31 and the second limiting member 41 are respectively rotated in conjunction with the first shaft 30 and the second shaft 40, and the two ends of the first limiting member 31 and the second limiting member 41 are respectively coupled to the first shaft 30. Forming a step difference with the second shaft 40, the first stopper 23 is located on the moving path of the first limiting member 31, so that the first stopping member 23 can selectively stop at both ends of the first limiting member 31. First, the rotation direction and angle of the first shaft 30 are restricted; the second stopper 24 is located on the moving path of the second limiting member 41, so that the second stopper 24 can be selectively stopped at the second limit. One of the two ends of the bit member 41, thereby restricting the direction and angle of rotation of the second shaft 40.
第一環體50係與第一軸30連動旋轉，第一環體50環設有第一外環面51與徑向內凹的第一凹弧部52，第一外環面51在剖面上屬於非全圓的優弧，而第一凹弧部52在剖面上則屬於劣弧。第二環體60與第二軸40連動旋轉且對應於第一環體50設置，第二環體60環設有第二外環面61與徑向內凹的第二凹弧部62，第二外環面61在剖面上屬於非全圓的優弧，而第二凹弧部62在剖面上則屬於劣弧。其中，第一凹弧部52與第二外環面61互補且可選擇性地彼此抵接以鎖定第一軸30，第二凹弧部62與第一外環面51互補且可選擇性地彼此抵接以鎖定第二軸40。換言之，第一凹弧部52與第二外環面61具有大體上相同的曲率，而第二凹弧部62與第一外環面51亦具有大體上相同的曲率。當第二外環面61與第一凹弧部52彼此抵接時，第一軸30會被鎖定而無法旋轉，因第二外環面61會卡住第一凹弧部52，使第一環體50無法旋轉，連帶使第一軸30無法旋轉，而此時第二軸40仍保有旋轉自由度，因第二外環面61可相對於第一凹弧部52旋轉。同樣的，當第一外環面51與第二凹弧部62彼此抵接時，第二軸40會被鎖定而無法旋轉，因第一外環面51會卡住第二凹弧部62，使第二環體60無法旋轉，連帶使第二軸40無法旋轉，而此時第一軸30仍保有旋轉自由度，因第一外環面51可相對於第二凹弧部62旋轉。The first ring body 50 is rotated in conjunction with the first shaft 30. The first ring body 50 is provided with a first outer annular surface 51 and a radially concave first concave arc portion 52. The first outer annular surface 51 is on the cross section. It belongs to a superior arc of a non-full circle, and the first concave arc portion 52 belongs to a poor arc in the cross section. The second ring body 60 rotates in conjunction with the second shaft 40 and is disposed corresponding to the first ring body 50. The second ring body 60 is provided with a second outer ring surface 61 and a radially concave second concave arc portion 62. The second outer annulus 61 is a superior arc of a non-full circle in cross section, and the second concave arc portion 62 is a sub-arc in the cross section. Wherein, the first concave arc portion 52 is complementary to the second outer annular surface 61 and selectively abuts each other to lock the first shaft 30, and the second concave arc portion 62 is complementary to the first outer annular surface 51 and selectively Abutting each other to lock the second shaft 40. In other words, the first concave arc portion 52 and the second outer annular surface 61 have substantially the same curvature, and the second concave arc portion 62 and the first outer annular surface 51 also have substantially the same curvature. When the second outer annular surface 61 and the first concave arc portion 52 abut each other, the first shaft 30 is locked and cannot rotate, because the second outer annular surface 61 will catch the first concave arc portion 52, so that the first The ring body 50 cannot be rotated, and the first shaft 30 is not rotatable, and the second shaft 40 still maintains rotational freedom, because the second outer ring surface 61 is rotatable relative to the first concave arc portion 52. Similarly, when the first outer annular surface 51 and the second concave arc portion 62 abut each other, the second shaft 40 is locked and cannot be rotated, because the first outer annular surface 51 will catch the second concave arc portion 62, The second ring body 60 is prevented from rotating, and the second shaft 40 is prevented from rotating, and the first shaft 30 still maintains a degree of rotational freedom, since the first outer ring surface 51 is rotatable relative to the second concave arc portion 62.
請同時參照第2至4圖，第4圖所示為循序鎖定式樞軸總成13於0度、180度與360度的作動狀態變化，其中為了便於示意而省略了部份元件。在本實施例中，第二環體60環繞固定於第二軸40，因此第二環體60與第二軸40連動，而第一環體50與第一軸30連動的方式則是利用主齒輪81與副齒輪82來達成。主齒輪81環繞固定於第一軸30，因而主齒輪81會隨第一軸30旋轉。副齒輪82與第一環體50軸向對齊且彼此相對固定，副齒輪82與第一環體50位於第一軸30與第二軸40之間且樞接第一支承板21與第二支承板22。主齒輪81與副齒輪82互相嚙合，因此當第一軸30旋轉時，主齒輪81會連動副齒輪82與第一環體50旋轉。在其他實施例中，亦可省略主齒輪與副齒輪，而直接將第一環體環繞固定於第一軸，並縮短第一軸與第二軸之間的軸距及/或加大第一環體與第二環體的半徑，使第一凹弧部與第二外環面以及第二凹弧部與第一外環面仍可選擇性地彼此抵接以鎖定第一軸或第二軸。Please refer to Figures 2 to 4 at the same time. Figure 4 shows the change of the operating state of the sequential locking pivot assembly 13 at 0, 180 and 360 degrees, wherein some of the components are omitted for ease of illustration. In this embodiment, the second ring body 60 is circumferentially fixed to the second shaft 40, so that the second ring body 60 is interlocked with the second shaft 40, and the first ring body 50 is interlocked with the first shaft 30 by using the main body. The gear 81 is achieved by the pinion gear 82. The main gear 81 is circumferentially fixed to the first shaft 30, and thus the main gear 81 rotates with the first shaft 30. The auxiliary gear 82 is axially aligned with the first ring body 50 and fixed relative to each other. The pin gear 82 and the first ring body 50 are located between the first shaft 30 and the second shaft 40 and pivotally connect the first support plate 21 and the second support. Board 22. The main gear 81 and the sub-gear 82 are in mesh with each other, so that when the first shaft 30 rotates, the main gear 81 rotates the sub-gear 82 and the first ring body 50. In other embodiments, the main gear and the auxiliary gear may be omitted, and the first ring body is directly fixed to the first shaft, and the wheelbase between the first shaft and the second shaft is shortened and/or the first is increased. a radius of the ring body and the second ring body such that the first concave arc portion and the second outer annular surface and the second concave arc portion and the first outer annular surface can still selectively abut each other to lock the first shaft or the second axis.
在本實施例中，主齒輪81的齒數大於副齒輪82的齒數，更進一步的，主齒輪81與副齒輪82的齒比為1.5，換言之，當主齒輪81轉0.5圈（即第一軸30旋轉180度），副齒輪82與第一環體50會轉0.75圈。除此之外，第三環體70環繞固定於第一軸30且毗鄰主齒輪81，第三環體70環設有第三外環面71，第三外環面71選擇性地接觸第一外環面51，亦即在第一軸30與第一環體50連動旋轉的過程中，除了第一凹弧部52面對第三環體70的時候，其餘過程中第一外環面51與第三外環面71係彼此接觸且相對旋轉，藉此可提高旋轉時的穩定度。其中，第一環體50、第二環體60與第三環體70彼此平行設置且位於第一支承板21與第二支承板22之間。需理解的是，在其他實施例中，所述主齒輪與副齒輪的齒比之值並不限於1.5，主齒輪與副齒輪之齒數與齒比的設計考量在於，當第一軸0度時，應使第一凹弧部不會接觸第二外環面，而當第一軸旋轉180度後，應使第一凹弧部會恰好面對第二凹弧部，以解除第二軸的鎖定。In the present embodiment, the number of teeth of the main gear 81 is larger than the number of teeth of the sub-gear 82. Further, the gear ratio of the main gear 81 to the sub-gear 82 is 1.5, in other words, when the main gear 81 is rotated 0.5 turn (ie, the first shaft 30) Rotating 180 degrees), the sub-gear 82 and the first ring body 50 will rotate 0.75 turns. In addition, the third ring body 70 is circumferentially fixed to the first shaft 30 and adjacent to the main gear 81, and the third ring body 70 is provided with a third outer ring surface 71, and the third outer ring surface 71 selectively contacts the first ring The outer annular surface 51, that is, during the rotation of the first shaft 30 in conjunction with the first ring body 50, except for the first concave arc portion 52 facing the third ring body 70, the first outer annular surface 51 in the remaining process The third outer annular surface 71 is in contact with each other and relatively rotated, whereby the stability at the time of rotation can be improved. The first ring body 50, the second ring body 60 and the third ring body 70 are disposed in parallel with each other and between the first support plate 21 and the second support plate 22. It should be understood that, in other embodiments, the ratio of the gear ratio of the main gear to the sub gear is not limited to 1.5, and the design of the gear ratio and the gear ratio of the main gear and the sub gear is: when the first axis is 0 degrees. The first concave arc portion should not be in contact with the second outer annular surface, and when the first shaft is rotated by 180 degrees, the first concave arc portion should face the second concave arc portion to release the second axial portion. locking.
以下說明循序鎖定式樞軸總成13的作動原理：The following describes the principle of operation of the sequential locking pivot assembly 13:
0度閉合狀態：第1圖所示為0度時第一板體11與第二板體12相對閉合的狀態，第3圖所示為0度時循序鎖定式樞軸總成13的狀態，第4圖(a)的上、下圖分別為0度時循序鎖定式樞軸總成13的前視（在上者）與後視（在下者）。在0度狀態時，第二凹弧部62與第一外環面51彼此抵接，第二凹弧部62受限於第一外環面51，因此使第二軸40被鎖定而無法旋轉，第一軸30則可旋轉，但第一限位件31的一端被第一止擋件23止擋，因此第一軸30僅具有逆時針（方向參照第4圖(a)下圖）旋轉的自由度。0 degree closed state: FIG. 1 shows a state in which the first plate body 11 and the second plate body 12 are relatively closed when 0 degrees, and FIG. 3 shows a state in which the step-locking pivot assembly 13 is 0 degrees. The upper and lower diagrams of Fig. 4(a) are the front view (above) and the rear view (below) of the sequential lock type pivot assembly 13 at 0 degrees, respectively. In the 0 degree state, the second concave arc portion 62 and the first outer annular surface 51 abut each other, and the second concave arc portion 62 is limited to the first outer annular surface 51, thereby making the second shaft 40 locked and unable to rotate. The first shaft 30 is rotatable, but one end of the first limiting member 31 is stopped by the first stopping member 23, so the first shaft 30 only has a counterclockwise direction (the direction is referred to in FIG. 4(a) below). The degree of freedom.
180度展開狀態：第5圖所示為180度時第一板體11相對於第二板體12展開的狀態，第6圖所示為180度時循序鎖定式樞軸總成13的狀態，第4圖(b)的上、下圖分別為180度時循序鎖定式樞軸總成13的前視（在上者）與後視（在下者）。由0度至180度時，係第一板體11相對於第二板體12展開了180度，連帶的第一軸30逆時針（方向參照第4圖(b)下圖）旋轉了180度，同時，主齒輪81與第一軸30連動旋轉了180度，即主齒輪81逆時針轉了0.5圈，並連動副齒輪82與第一環體50順時針旋轉0.75圈，因此第一凹弧部52順時針旋轉0.75圈後面對第二凹弧部62。此時，第一限位件31在旋轉180度後其另一端再度被第一止擋件23止擋，因此第一軸30無法繼續逆時針（方向參照第4圖(b)下圖）旋轉。由於第二凹弧部62不再受限於第一外環面51，因此第二軸40的鎖定解除，但第二限位件41的一端被第二止擋件24止擋，此時第二軸40僅具有順時針（方向參照第4圖(b)下圖）旋轉的自由度。180 degree unfolded state: Fig. 5 shows a state in which the first plate body 11 is unfolded relative to the second plate body 12 at 180 degrees, and Fig. 6 shows a state in which the sequential locking type pivot assembly 13 is at 180 degrees, The upper and lower diagrams of Fig. 4(b) are the front view (above) and the rear view (below) of the sequential lock type pivot assembly 13 at 180 degrees, respectively. When the temperature is from 0 degrees to 180 degrees, the first plate body 11 is unfolded by 180 degrees with respect to the second plate body 12, and the associated first axis 30 is rotated counterclockwise (the direction is referred to in FIG. 4(b) below) by 180 degrees. At the same time, the main gear 81 rotates 180 degrees in conjunction with the first shaft 30, that is, the main gear 81 rotates counterclockwise by 0.5 turns, and the interlocking pin gear 82 and the first ring body 50 rotate clockwise by 0.75 turns, so the first concave arc The portion 52 is rotated clockwise by 0.75 turns to the second concave arc portion 62. At this time, after the first limiting member 31 is rotated by 180 degrees, the other end thereof is again stopped by the first stopper 23, so the first shaft 30 cannot continue to rotate counterclockwise (the direction is referred to FIG. 4(b) below). . Since the second concave arc portion 62 is no longer limited by the first outer annular surface 51, the locking of the second shaft 40 is released, but one end of the second limiting member 41 is stopped by the second stopping member 24, at this time The two shafts 40 have only the degree of freedom of rotation in the clockwise direction (see Fig. 4(b) below).
360度展開狀態：第7圖所示為360度時第一板體11與第二板體12完全展開的狀態，第8圖所示為360度時循序鎖定式樞軸總成13的狀態，第4圖(c)的上、下圖分別為360度時循序鎖定式樞軸總成13的前視（在上者）與後視（在下者）。由180度至360度時，係第二板體12相對於第一板體11展開了180度，連帶的第二軸40順時針（方向參照第4圖(c)下圖）旋轉了180度，同時，第二環體60連動旋轉0.5圈，因此第二凹弧部62旋轉0.5圈後與第一凹弧部52相背，而第一凹弧部52與第二外環面61彼此抵接，第一凹弧部52受限於第二外環面61，因此使第一軸30被鎖定而無法旋轉。此時，第二限位件41在旋轉180度後其另一端再度被第二止擋件24止擋，因此第二軸40無法繼續順時針（方向參照第4圖(c)下圖）旋轉而僅具有逆時針旋轉的自由度。360 degree unfolded state: Fig. 7 shows a state in which the first plate body 11 and the second plate body 12 are fully unfolded at 360 degrees, and Fig. 8 shows a state of the sequential locking type pivot assembly 13 at 360 degrees, The upper and lower diagrams of Fig. 4(c) are the front view (above) and the rear view (below) of the sequential lock type pivot assembly 13 at 360 degrees, respectively. From 180 degrees to 360 degrees, the second plate body 12 is unfolded 180 degrees with respect to the first plate body 11, and the associated second shaft 40 is rotated clockwise (the direction is shown in Fig. 4 (c) below) by 180 degrees. At the same time, the second ring body 60 is rotated by 0.5 turns, so that the second concave arc portion 62 rotates 0.5 turns and is opposite to the first concave arc portion 52, and the first concave arc portion 52 and the second outer annular surface 61 abut each other. Then, the first concave arc portion 52 is limited to the second outer annular surface 61, so that the first shaft 30 is locked and cannot be rotated. At this time, after the second limiting member 41 is rotated 180 degrees, the other end thereof is again stopped by the second stopper 24, so the second shaft 40 cannot continue to rotate clockwise (the direction is referred to the following figure in FIG. 4(c)). It only has the freedom of counterclockwise rotation.
承上，當使用者欲將電子裝置10由360度狀態逆向扳回0度狀態時，則因為在360度狀態下第一軸30被鎖定，需由第二軸40先轉180度（如第4圖(c)至第4圖(b)），之後第二軸40被鎖定，再由第一軸30轉180度（如第4圖(b)至第4圖(a)），回到0度狀態。其作動原理請參照前述說明，於此不再贅述。In the case that the user wants to reverse the electronic device 10 from the 360 degree state to the 0 degree state, since the first axis 30 is locked in the 360 degree state, the second axis 40 needs to be rotated 180 degrees first (eg, 4 (c) to 4 (b)), after which the second shaft 40 is locked and then rotated 180 degrees by the first shaft 30 (as shown in Figs. 4(b) to 4(a)), returning 0 degree status. Please refer to the above description for the principle of its operation, and will not be repeated here.
