本新型詳細說明及技術內容，茲配合圖式說明如下：The detailed description and technical content of this new model are described as follows in conjunction with the drawings:

請參閱圖1至圖4，本新型提供一種具扭力變化的單軸鉸鏈100，該單軸鉸鏈100應用於一電子產品(圖中未示)中。該單軸鉸鏈100具有一第一轉動件10以及一提供該第一轉動件10設置的轉軸30，該第一轉動件10與該轉軸30分別與該電子產品的其中一部件組接，該第一轉動件10包含一第一組接部11及一連接該第一組接部11的第一安裝部12，其中，本新型該第一組接部11是由兩間隔設置的弧形臂111，一由該二弧形臂111共同界定的空間112及一位於該二弧形臂111之間並連通該空間112的開口113組成。該二弧形臂111其中之一成形有一切平面114，需了解到，該二弧形臂111面對該空間112的一側基礎是以一弧面115實施。另一方面，該轉軸30組接該第一組接部11的部分截面非圓而具有一凸點31，需了解到本文雖以該凸點31進行說明，但此部分是以截面來看，但如果是從該轉軸30的立體角度來看，該轉軸30提供該第一組接部11組裝的部分將成形一***。Please refer to FIG. 1 to FIG. 4 , the present invention provides a uniaxial hinge 100 with variable torsion, and the uniaxial hinge 100 is used in an electronic product (not shown in the figure). The single-axis hinge 100 has a first rotating member 10 and a rotating shaft 30 provided with the first rotating member 10. The first rotating member 10 and the rotating shaft 30 are respectively assembled with one of the components of the electronic product. A rotating member 10 includes a first assembling portion 11 and a first mounting portion 12 connected to the first assembling portion 11 , wherein the first assembling portion 11 of the present invention is composed of two arc-shaped arms 111 arranged at intervals , a space 112 defined by the two arc-shaped arms 111 and an opening 113 located between the two arc-shaped arms 111 and communicating with the space 112 is composed. One of the two arc-shaped arms 111 is formed with a flat surface 114 , and it should be understood that one side of the two arc-shaped arms 111 facing the space 112 is implemented with an arc surface 115 . On the other hand, the part of the rotating shaft 30 assembled with the first assembly part 11 has a non-circular cross-section and has a convex point 31. It should be understood that although the convex point 31 is used in the description, this part is viewed from a cross-section. However, if viewed from the perspective of the rotating shaft 30 , the portion of the rotating shaft 30 where the first assembly portion 11 is assembled will form a bulge.

請參閱圖5至圖8，以下針對該單軸鉸鏈100作動方式進行說明，本新型該單軸鉸鏈100具有三種不同扭力狀態，以下將依序說明這三種狀態:Please refer to FIG. 5 to FIG. 8 . The following describes the operation mode of the uniaxial hinge 100. The uniaxial hinge 100 of the present invention has three different torsion states. The three states will be described in sequence below:

請搭配圖5與圖8，圖5狀態是假設該單軸鉸鏈100預備開啟時，當該第一轉動件10受力而相對該轉軸30轉動，使位於該開口113內的該凸點31朝向該二弧形臂111其中之一活動，由於該第一轉動件10需受力達到得以克服該凸點31所帶來的限制，而產生了一開啟扭力，如圖8中一第一扭力區段200所示，此稱之為一第一扭力狀態。Please refer to FIG. 5 and FIG. 8. In the state of FIG. 5, it is assumed that when the single-axis hinge 100 is ready to be opened, when the first rotating member 10 is forced to rotate relative to the rotating shaft 30, the convex point 31 located in the opening 113 faces One of the two arc-shaped arms 111 is active. Since the first rotating member 10 needs to be forced to overcome the restriction brought by the convex point 31, an opening torque is generated, such as a first torque zone in FIG. 8 . As shown in segment 200, this is referred to as a first torque state.

續搭配圖6與圖8，圖6所示可為該單軸鉸鏈100經圖5狀態並持續朝同一方向展開的實施示意。於圖6狀態，該第一轉動件10持續受力而令該凸點31滑移於該二弧形臂111其中之一面對該空間112一側，此時由於該凸點31滑移於該二弧形臂111其中之一面對該空間112一側的該弧面115部分，於扭力產生上沒有明顯起伏，如圖8中一第二扭力區段201所示，而此狀態即稱為本新型該單軸鉸鏈100的一第二狀態。Continuing with FIG. 6 and FIG. 8 , FIG. 6 shows a schematic diagram of the implementation of the uniaxial hinge 100 passing through the state of FIG. 5 and continuously unfolding in the same direction. In the state shown in FIG. 6 , the first rotating member 10 is continuously subjected to force to cause the convex point 31 to slide on the side of one of the two arc-shaped arms 111 facing the space 112 . One of the two arc-shaped arms 111 faces the part of the arc surface 115 on the side of the space 112 , and there is no obvious fluctuation in torsion force generation, as shown in a second torsion force section 201 in FIG. 8 , and this state is called This is a second state of the uniaxial hinge 100 of the present invention.

接續圖7與圖8，圖7所示可為該單軸鉸鏈100經圖6狀態並持續朝同一方向展開的實施示意。於圖7狀態，該第一轉動件10持續受力而令該凸點31滑移於該二弧形臂111其中之一上的該切平面114時，因該切平面114改變了該凸點31原本的軌跡，且該空間112中心點至該切平面114的距離小於該空間112中心點至該弧面115的距離，使得該第一轉動件10一旦持續轉動，將會因前述結構的變化而受到壓迫，產生不同於該第一狀態與該第二狀態的扭力，如圖8中一第三扭力區段202所示，此狀態即稱為本新型該單軸鉸鏈100的一第三狀態。Continuing from FIGS. 7 and 8 , FIG. 7 shows an implementation schematic diagram of the uniaxial hinge 100 going through the state of FIG. 6 and continuing to unfold in the same direction. In the state shown in FIG. 7 , when the first rotating member 10 is continuously subjected to force to cause the convex point 31 to slide on the tangent plane 114 on one of the two arc-shaped arms 111 , the convex point is changed by the tangent plane 114 31 the original trajectory, and the distance from the center point of the space 112 to the tangent plane 114 is smaller than the distance from the center point of the space 112 to the arc surface 115, so that once the first rotating member 10 continues to rotate, it will be due to the aforementioned structural changes Under pressure, a torsion force different from the first state and the second state is generated, as shown in a third torsion section 202 in FIG. 8 , this state is called a third state of the uniaxial hinge 100 of the present invention .

復請參閱圖1至圖3，一實施例中，該第一組接部11以該第一扭力狀態中與該凸點31接觸的該二弧形臂111其中之一末端為圓心角0度，該弧面115位於圓心角0至99.6度之間，該切平面114則位於圓心角的99.6度至140度之間。Please refer to FIG. 1 to FIG. 3 again. In one embodiment, the first assembly portion 11 is in the first torsion state and one of the ends of the two arc-shaped arms 111 in contact with the convex point 31 has a central angle of 0 degrees. , the arc surface 115 is located between 0 and 99.6 degrees of the central angle, and the tangent plane 114 is located between 99.6 degrees and 140 degrees of the central angle.

復請參閱圖1至圖3，為限制該單軸鉸鏈100的轉動角度，一實施例中，該單軸鉸鏈100包含一與該第一轉動件10組接的第二轉動件20，該第一轉動件10與該第二轉動件20以至少一固定件40組裝並同時相對該轉軸30轉動，該第二轉動件20包含一第二組接部21以及一連接該第二組接部21並可與該第一安裝部12組接的第二安裝部22。該轉軸30包含一用以限制該第二轉動件20轉動角度的止擋塊32，該第二轉動件20於相對該轉軸30轉動一角度時將以該第二組接部21與該第二安裝部22的銜接處抵頂該止擋塊32。進一步地，該止擋塊32可根據該單軸鉸鏈100的開啟需求來設計該止擋塊32上的至少一止擋面321位置，於本實施例中，該止擋塊32令該第二轉動件20僅能旋轉120度即受到限制。另一方面，一實施例中，該第二轉動件20具有一設於該第二組接部21與該第二安裝部22銜接處的凸塊23，該凸塊23具有兩斜面231，該二斜面231的長度不一。Please refer to FIG. 1 to FIG. 3 , in order to limit the rotation angle of the single-axis hinge 100 , in one embodiment, the single-axis hinge 100 includes a second rotating member 20 assembled with the first rotating member 10 .

The joint of the mounting portion 22 abuts against the stopper 32 . Further, the position of at least one stop surface 321 on the stop block 32 can be designed according to the opening requirement of the single-axis hinge 100 . In this embodiment, the stop block 32 makes the second stop The rotating member 20 can only rotate 120 degrees, which is limited.
