Description

扭力可變形樞軸器 Torsion deformable pivot

本創作係有關於一種樞軸裝置的技術領域，特別是有關於一種在兩個相對設的凸輪上藉由凸塊與斜面相對移動的結構的扭力可變形樞軸器。 This creation relates to the technical field of a pivot device, in particular to a torsionally deformable pivot device with a structure in which two opposite cams move relative to each other by a convex block and an inclined surface.

筆記型電腦具有主機與螢幕，螢幕通常藉由樞軸裝置連接於主機，當使用者不使用筆記型電腦時，螢幕可以藉由樞軸裝置蓋合於主機。當使用者需要使用筆記型電腦時，使用者將螢幕藉由樞軸裝置相對於主機旋轉掀開使用。 A notebook computer has a host and a screen. The screen is usually connected to the host by a pivot device. When the user is not using the notebook computer, the screen can be covered on the host by the pivot device. When the user needs to use the notebook computer, the user rotates the screen relative to the host by the pivot device and uses it.

現有的筆記型電腦的樞軸器在掀開螢幕時，使用者必須要克服軸孔間的摩擦力，會顯得比較費力才能掀開螢幕，而且當螢幕掀開至希望的角度後，例如掀開至90度角時，螢幕容易晃動。 When opening the screen of the existing notebook computer pivot, the user has to overcome the friction between the shaft holes, which is more laborious to open the screen, and when the screen is opened to a desired angle, for example, when the screen is opened to a desired angle, the user has to overcome the friction between the shaft holes. When the angle reaches 90 degrees, the screen is easy to shake.

現有的樞軸器如第1圖所示，其具有相互抵接的第一凸輪A1及第二凸輪A2，第一凸輪A1具有一凹部A11，第二凸輪A2抵接於一扭力模組B且具有一凸部A21，藉由第二凸輪A2的凸部A21從第一凸輪A1的平面進入凹部A11，使樞軸器連接的螢幕可省力掀開至一定位角度，藉由第二凸輪A2的凸部A21從第一凸輪A1的凹部A11上升至平面，使螢幕要掀開更大 角度必須費力，藉此使螢幕在定位角度不容易搖晃。但是上述的結構會使扭力產生急遽的變化，讓使用者掀開螢幕的過程容易產生不順暢的問題。 As shown in Figure 1, the existing pivot has a first cam A1 and a second cam A2 that abut against each other. The first cam A1 has a recess A11, and the second cam A2 abuts against a torque module B and It has a convex part A21. The convex part A21 of the second cam A2 enters the concave part A11 from the plane of the first cam A1, so that the screen connected by the pivot can be opened to a positioning angle with less effort. The convex part A21 rises from the concave part A11 of the first cam A1 to the plane, so that the screen needs to be opened larger The angle must be laborious, so that the screen is not easy to shake at the positioning angle. However, the above-mentioned structure will cause a sudden change in the torque, which makes the process of turning the screen open by the user prone to unsmooth problems.

有鑑於此，本創作的目的在於提供一種扭力可變形樞軸器，其，使得扭力可變形樞軸器所連接的螢幕與主機在不同的角度範圍提供不同的扭力值，而且使扭力值的變化平緩，以便讓使用者輕鬆而且順暢地掀開螢幕，而且在螢幕掀開至希望的角度後，可以避免螢幕晃動。 In view of this, the purpose of this creation is to provide a torsion deformable pivot, which enables the screen and the host connected to the torsion deformable pivot to provide different torque values in different angle ranges, and to change the torque value Gentle, so that users can easily and smoothly open the screen, and after the screen is opened to a desired angle, it can prevent the screen from shaking.

Then the bump is located between the first inclined plane and the second inclined plane. If the screen is to be opened to a larger angle, the bump will rise from the plane from the second inclined plane, so that the torsion element of the torsion module is compressed, and the torque value gradually Make it larger, so that the screen will not shake after being opened to the position.

如第6圖所示，第一連接件10與第二連接件間為第一角度(0度)，此時第二凸輪件50的凸塊511位於第一凸輪件30的第一斜面331的最高處，接著如第7圖、第8圖及第9圖所示，當使用者掀開筆記型電腦的螢幕時，軸體12帶動第二凸輪件50旋轉，使第一連接件10與第二連接件20間從0度角逐漸增加成為22度和45度，最後形成第二角度(90度)，此時凸塊511沿著第一斜面331移動下降直到平面333，藉此使扭力模組60的扭力件61的扭力逐漸被釋放，使得使用者可以輕鬆地掀開螢幕，而且由於扭力件61的 扭力是緩慢地釋放，因此螢幕掀開的動作可以平緩地進行。如第10圖所示，當第一連接件10與第二連接件20間的角度要形成更大的第三角度(180度)時，凸塊511須從平面333沿第二斜面332上升，此時扭力模組60的扭力件61會再度被壓縮而使扭力增加，藉此當第一連接件10與第二連接件20間的角度在第二角度時，可以避免螢幕產生搖晃。 As shown in Figure 6, there is a first angle (0 degrees) between the first connecting member 10 and the second connecting member. At this time, the protrusion 511 of the second cam member 50 is located on the first inclined surface 331 of the first cam member 30. At the highest point, as shown in Figures 7, 8 and 9, when the user opens the screen of the notebook computer, the shaft 12 drives the second cam member 50 to rotate, so that the first connecting member 10 and the second connecting member 10 are rotated. The angle between the two connecting pieces 20 gradually increases from 0 degrees to 22 degrees and 45 degrees, and finally forms a second angle (90 degrees). At this time, the protrusion 511 moves and descends along the first inclined surface 331 to the plane 333, thereby making the torsion mode The torque of the torsion member 61 of the group 60 is gradually released, so that the user can easily open the screen, and due to the torsion member 61 Torque is released slowly, so the movement of opening the screen can be done smoothly. As shown in Figure 10, when the angle between the first connecting member 10 and the second connecting member 20 is to form a larger third angle (180 degrees), the bump 511 must rise from the plane 333 along the second inclined plane 332, At this time, the torsion member 61 of the torsion module 60 will be compressed again to increase the torque, so that when the angle between the first connecting member 10 and the second connecting member 20 is at the second angle, the screen can be prevented from shaking.

請參閱第11圖，其表示本創作的扭力可變形樞軸器的另一實施例。本實施例的結構與前一實施例的結構是部分相同，因此相同的構件給予相同的符號並省略其說明。本實施例的扭力模組60是抵接於第二凸輪件50，而第一凸輪件30則是經由定位軸孔的配合而定位在固定件40。藉由與前述實施力相同的第一凸輪件30與第二凸輪件50的抵接及相對運動，使扭力模組60的擰力產生平緩的變化，使螢幕省力地被掀開，而且在定位角度(第二角度)時不會晃動。 Please refer to Figure 11, which shows another embodiment of the torsion deformable pivot of the present invention. The structure of this embodiment is partially the same as that of the previous embodiment, so the same components are given the same symbols and their descriptions are omitted. The torque module 60 of this embodiment abuts against the second cam member 50, and the first cam member 30 is positioned on the fixing member 40 through the cooperation of the positioning shaft hole. By the abutment and relative movement of the first cam member 30 and the second cam member 50 with the same force as the aforementioned implementation force, the twisting force of the torsion module 60 is changed gently, so that the screen can be opened with less effort, and it is in positioning. The angle (second angle) will not shake.

本創作的扭力可變形樞軸器藉由第二凸輪件的凸塊與第一凸輪件的第一斜面、平面及第二斜面抵接，使得當凸塊在第一斜面下降至平面時，扭力模組的扭力件釋放，扭力值逐漸變小，使螢幕得以省力且平順地被掀開。然後凸塊位在第一斜面與第二斜面之間，若螢幕要掀開更大的角度，則凸塊會從平面從第二斜面上升，使扭力模組的扭力件被壓縮，扭力值逐漸變大，藉此使螢幕掀開至定位後不會晃動。 The torsion-deformable pivot of the present invention abuts against the first inclined surface, the plane and the second inclined surface of the first cam member by the convex block of the second cam member, so that when the convex block descends to the plane on the first inclined surface, the torsion force The torque of the module is released, and the torque value gradually decreases, so that the screen can be opened smoothly and effortlessly. Then the bump is located between the first inclined plane and the second inclined plane. If the screen is to be opened to a larger angle, the bump will rise from the plane from the second inclined plane, so that the torsion element of the torsion module is compressed, and the torque value gradually Make it larger, so that the screen will not shake after being opened to the position.
