Description

Notebook computer rotating shaft

Technical Field

The utility model relates to a notebook pivot technical field specifically is a notebook pivot.

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 360 degrees flipped, e.g. associative Yoga series. The WLAN antenna of such notebook is usually placed at the rotation axis to ensure that the WLAN antenna does not generate large displacement 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, WLAN antenna being close to the human body) with the risk of too high SAR. How to ensure that the efficiency of the full frequency band of the WLAN antenna is higher than the network access requirement in two states 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.
