Description

Notebook computer rotating shaft

Technical Field

The invention relates to the technical field of notebook rotating shafts, in particular to a notebook rotating shaft.

Background

More and more notebooks support two modes of operation (2 in 1 notebooks): 1. normal notebook mode with screen 110 degrees open, 2. tablet mode with screen turned 360 degrees, e.g. associative Yoga series. The WLAN antenna of such notebooks is usually placed at the hinge in order to ensure that the WLAN antenna does not displace significantly with the turning of the screen. The antenna placement here results in the antenna being too close to the human body in some application scenarios in both modes (normal mode and flat mode placed on the thigh or belly, with the WLAN antenna close to the human body), with the risk of too high SAR. How to ensure that the efficiency of a full frequency band of a WLAN antenna in two states is higher than the network access requirement and the SAR value is lower than the safety standard becomes a design problem in the industry, and therefore, a notebook rotating shaft is provided.
