In order to facilitate the user's operation, the screen design can be rotated on the seat, for example, the Republic of China Announcement No. I499896, however, the above method is nothing more than the use of the track, so that the screen or keyboard can be displaced by the track, but the screen or keyboard In positioning, it is necessary to use the card 榫, bump interference, etc. for positioning, in addition to the design of a more complex structure, less convenient operation, production is relatively difficult, and the electronic device can not be light and thin Short, small trend development.
本發明之主要目的乃在於，利用限位裝置之限位件內所設置的樞軸件，讓限位件於樞軸件上轉動時產生磨擦力，俾使限位件受外力驅動樞轉時，產生無段定位之效果，且結構簡單便於利用，並可使電子產品有效的趨向輕、薄、短、小之設計。The main purpose of the present invention is to utilize the pivoting member provided in the limiting member of the limiting device to generate a frictional force when the limiting member rotates on the pivoting member, so that when the limiting member is driven to be pivoted by an external force The utility model has the advantages of no segment positioning, simple structure and convenient use, and can effectively make the electronic product tend to be light, thin, short and small.
本發明之次要目的乃在於，利用限位裝置之限位件內所設置的樞軸件，讓限位件於樞軸件上以不同方向轉動時，產生大小不同之磨擦力，以符合電子產品開啟或關閉時所需之扭力The secondary object of the present invention is to use the pivot member disposed in the limiting member of the limiting device to cause the limiting member to rotate in different directions on the pivot member to generate frictional forces of different sizes to conform to the electronic Torque required to turn the product on or off
為達上述目的，本發明之扭力限位裝置係設置有樞軸件以及限位件，樞軸件係具有基部，基部側方延伸有彈性臂，彈性臂與基部之間形成有彈性空間，且彈性臂遠離彈性空間之另側表面形成有圓弧狀之貼抵面；限位件係具有本體，本體內設置有圓形之樞接孔，且本體於樞接孔之內壁形成有抵靠面，外側環形設置有傳動齒，且樞接孔係樞接於樞軸件外側，使樞軸件之貼抵面貼抵於限位件之抵靠面，且彈性臂受抵靠面之限制而朝向彈性空間彈性位移，進而產生復位能力，讓限位件於傳動齒受外力推動樞轉時，貼抵面與抵靠面之間產生磨擦力。In order to achieve the above object, the torsion limiting device of the present invention is provided with a pivoting member and a limiting member, the pivoting member has a base portion, the base portion has a resilient arm extending laterally, and an elastic space is formed between the elastic arm and the base portion, and The elastic arm is formed with an arc-shaped abutting surface away from the other side surface of the elastic space; the limiting member has a body, the body is provided with a circular pivoting hole, and the body is formed with an abutting on the inner wall of the pivoting hole The outer ring is provided with a transmission tooth, and the pivot hole is pivotally connected to the outer side of the pivot member, so that the abutting surface of the pivot member abuts against the abutting surface of the limiting member, and the elastic arm is restricted by the abutting surface The elastic displacement toward the elastic space, thereby generating a resetting force, causes the limiting member to generate a frictional force between the abutting surface and the abutting surface when the transmission tooth is driven to be pivoted by an external force.
再者，前述之樞軸件其基部二端形成有第一端部與第二端部，基部由第一端部朝向第二端部延伸有第一彈性臂，第二端部朝向第一端部延伸有第二彈性臂，第一彈性臂與第二彈性臂位於基部不同側方，而第一彈性臂與基部之間形成有第一彈性空間，第一彈性臂於遠離第一彈性空間另側表面形成有圓弧狀之第一貼抵面，且第一彈性臂末端與基部之間形成有第一缺口，而第二彈性臂與基部之間形成有第二彈性空間，第二彈性臂於遠離第二彈性空間另側表面形成有圓弧狀之第二貼抵面，且第二彈性臂末端與基部之間形成有第二缺口，俾使限位件於傳動齒受外力推動樞轉時，貼抵面與抵靠面之間產生磨擦力，且限位件樞轉方向不同時，貼抵面與抵靠面之間產生之磨擦力亦不相同。Furthermore, the aforementioned pivot member has a first end portion and a second end portion formed at two ends thereof, and the base portion has a first elastic arm extending from the first end portion toward the second end portion, and the second end portion faces the first end The second elastic arm and the second elastic arm are located on different sides of the base, and a first elastic space is formed between the first elastic arm and the base, and the first elastic arm is away from the first elastic space. The side surface is formed with an arc-shaped first abutting surface, and a first notch is formed between the end of the first elastic arm and the base, and a second elastic space is formed between the second elastic arm and the base, and the second elastic arm is formed. An arc-shaped second abutting surface is formed on the other side surface away from the second elastic space, and a second notch is formed between the end of the second elastic arm and the base portion, so that the limiting member is pivoted by the external force on the transmission tooth. When the frictional force is generated between the abutting surface and the abutting surface, and the pivoting direction of the limiting member is different, the frictional force generated between the abutting surface and the abutting surface is also different.
請參閱第一圖至第三圖所示所示，由圖中可清楚看出，本發明係設置有樞軸件1以及限位件2，其中：Referring to the first to third figures, it is clear from the drawings that the present invention is provided with a pivot member 1 and a limit member 2, wherein:
該樞軸件1係具有基部11，基部11表面設置有定位孔111，基部11側方延伸有彈性臂12，彈性臂12為複數設置，彈性臂12係由基部11二側朝向相同側方延伸所形成，彈性臂12與基部11之間形成有彈性空間13，各彈性臂12遠離彈性空間13之另側表面形成有圓弧狀之貼抵面121，二彈性臂12末端形成有缺口14。The pivoting member 1 has a base portion 11. The surface of the base portion 11 is provided with a positioning hole 111. The base portion 11 has a resilient arm 12 extending laterally. The elastic arm 12 is provided in plural. The elastic arm 12 extends from the two sides of the base portion 11 toward the same side. An elastic space 13 is formed between the elastic arm 12 and the base portion 11. The other side surface of each elastic arm 12 away from the elastic space 13 is formed with an arc-shaped abutting surface 121, and the ends of the two elastic arms 12 are formed with a notch 14.

The positioning member 4 is positioned on the substrate 3, and the base portion 11 of the pivoting member 1 is fixed to the base portion 11. The pivoting hole 22 of the limiting member 2 is pivotally connected to the outer side of the pivoting member 1 so that the abutting surface 121 of the pivoting member 1 abuts against the abutting surface 211 of the limiting member 2, and the elastic arm 12 is elastically displaced toward the elastic space 13 by the abutment surface 211, thereby generating a restoring capability, and the elastic restoring capability generated by the elastic arm 12 causes a frictional force between the abutting surface 121 and the abutting surface 211; Referring to the second figure, when the limiting member 2 is pushed by the external force on the driving tooth 23, and the external force is greater than the frictional force generated between the abutting surface 121 and the abutting surface 211, the limiting member 2 is pivoted. The shaft member 1 is pivoted. Further, since the elastic arm 12 is formed by extending the two sides of the base portion 11 toward the same side, when the limiting member 2 is pivoted, the pivoting direction thereof and the elastic arm 12 must be The extending direction is the same, and the extending direction of the other elastic arm 12 is opposite, so the frictional force generated by the abutting surface 121 and the abutting surface 211 is not limited by the limit. 2 differs pivoting direction changes.
