Description

Technical Field

[0001] The invention relates to the technical field of notebook hinges, in particular to a notebook hinge. Background Art

[0002] More and more notebooks support two working modes (2-in-1 notebooks): 1. Normal notebook mode with the screen open 110 degrees, 2. Tablet mode with the screen flipped 360 degrees, such as Lenovo Yoga series. The WLAN antenna of such notebooks is usually placed at the hinge to ensure that the WLAN antenna does not move significantly with the flipping of the screen. Placing the antenna here will cause the antenna to be too close to the human body in some application scenarios in both modes (normal mode and tablet mode are placed on the thigh or stomach, and the WLAN antenna is close to the human body), posing a risk of excessive SAR. How to ensure that the efficiency of the WLAN antenna in the full frequency band in both states is higher than the network access requirements while the SAR value is lower than the safety standard has become a design problem in the industry. To this end, we provide a notebook hinge. Summary of the invention
