Description

Two-Segment Computer Pivot

technical field

The utility model relates to a notebook computer pivot, in particular to a two-stage pivot, which can make the notebook computer easy to open and precisely locates the computer pivot.

Background technique

When the pivot of the notebook computer is in the open state, it is often necessary to hold the screen with one hand and the body with the other hand, so that the screen will not drive the body upwards when it is turned on.

Refer to China Authorized Announcement No. CN2821654Y "Rotating Shaft Structure Applied to Notebook Computers", wherein the rotating shaft structure is a C-shaped annular body made of metal. When the liquid crystal display module is opposite to the gap of the annular body For rotation, when the rotating shaft rotates, there is no supporting point with the gap of the ring body so that there is no friction, and the relative torque value becomes smaller, so that the liquid crystal display module can be opened with less effort. When the liquid crystal display module is closed, it is forward to the gap of the ring body When rotating, the frictional force between the rotating shaft and the annular body becomes larger, and the relative torque value also becomes larger, so that the liquid crystal display module has to be closed with more effort.

The existing rotating shaft only sets the gap with the annular body to control the positioning effect through the amount of friction, but it cannot do effective and accurate positioning, and this kind of surface-to-surface friction will last for a long time. When the two metals pass through continuously wear, the effect of the friction positioning will disappear due to wear. The rotating shaft cannot be easily opened, but is positioned in the positioning state. In view of the above-mentioned deficiencies, the inventor has made continuous experiments on how to make the rotating part accurately positioned and meet the high-quality requirements. The utility model is a two-stage computer pivot, hoping to improve various existing technical problems to be solved.
