Description

Pivot device

This creation mainly discloses a pivot, especially a pivot device installed in an electronic product.

As technology becomes more developed, people's dependence on electronic products is increasing. In order to be able to get information after going out, more and more people will not only carry smart phones, but also carry tablet computers. Even carrying a notebook computer can meet the needs of users. In order to make the screen and keyboard of the notebook computer relatively rotate, the pivot is the necessary component for connecting the screen and the keyboard, and the tablet computer also has a dedicated external keyboard, the keyboard itself. That is, it can pivot relative to the tablet computer. In addition to being rugged and durable, in order to make the notebook or tablet computer easy to use, it must also have a function of limiting the angle and automatically returning to the original position, so that the screen can only be specified. The angle between the angles is relative to the keyboard, and the screen automatically rebounds to the proper position when it is about to be closed on the keyboard.

However, in order to achieve the function of limiting the angle of the pivot and automatically returning to the original position, additional components must be added to the pivot, resulting in an increase in the volume and weight of the pivot, which in turn results in a bulky and heavy product. It does not meet the needs of modern people who want to carry electronic products for a long time and hope that electronic products can be lightweight.
