双轴扭力枢轴器同步机构Biaxial Torsion Pivot Synchronization Mechanism

技术领域technical field

本实用新型有关一种双轴扭力枢轴器同步机构，尤指能以更精简的构件，使此类扭力枢轴器的双轴同步进行设定角度或变形时的开启及闭合动作。The utility model relates to a synchronous mechanism of a double-axis torsion pivot, especially refers to the ability to use simpler components to enable the two-axis of this type of torsion pivot to simultaneously perform opening and closing actions when setting an angle or deforming.

背景技术Background technique

以笔记型电脑之类电子设备为例，大致上含有一主机系统端（主机）及一可供掀开的液晶显示萤幕端（上盖），两者在一相对端部以枢轴器连接，供在使用时能以该枢轴器为动作轴心掀开上盖的液晶显示萤幕进行操作，或在不使用时反向将两者相对闭合。Taking electronic equipment such as notebook computers as an example, it generally includes a host system end (host) and a liquid crystal display screen end (top cover) that can be opened, and the two are connected by a pivot at an opposite end. When in use, the liquid crystal display screen of the upper cover can be opened with the pivot as the action axis for operation, or reversely closed when not in use.

为方便将显示萤幕上盖开启到定点角度以及将整个笔记型电脑翻折变形成平板态样，现有笔记型电脑大都采用双轴扭力枢轴器来进行开启角度定位及大角度翻折的主要机构。In order to facilitate the opening of the display screen cover to a fixed angle and the folding of the entire notebook computer into a flat form, most of the existing notebook computers use a two-axis torsion pivot to position the opening angle and fold it at a large angle. mechanism.

现有双轴扭力枢轴器的结构主要是具有一第一转轴与上盖显示萤幕一同转动，及一第二转轴与主机系统端一同转动。但现有此类使用双轴式的枢轴器在打开较大角度，或要使显示端及系统端变形翻折360°的互迭状态时，通常先使其中一轴旋转到特定角度后，再切换至另一轴旋转，除了整个显示端及系统端的同步翻折机构相当复杂，制造及组装上较费事、成本较高之外，显示端及系统端的翻折动作上缓慢与不顺畅，同时，使用者在进行360°互迭翻折动作或以同样的反向动作回复关闭状态的操作上，必须透过双轴的其中一轴进行转动到一设定角度后，再由双轴的另一轴进行转动控制，较为麻烦与不方便。The structure of the existing dual-axis torsion pivot mainly has a first rotating shaft that rotates together with the display screen of the upper cover, and a second rotating shaft that rotates together with the host system end. However, when the existing two-axis pivots are opened at a large angle, or when the display end and the system end are to be deformed and folded to a 360° overlapping state, one of the axes is usually rotated to a specific angle first. Then switch to another axis of rotation. In addition to the complex synchronous folding mechanism of the entire display end and the system end, which is more laborious and costly to manufacture and assemble, the folding action of the display end and the system end is slow and not smooth. At the same time , the user must rotate to a set angle through one of the two axes when performing 360° mutual folding action or returning to the closed state with the same reverse action, and then the other two axes must rotate to a set angle. It is troublesome and inconvenient to control the rotation of one axis.
