AI Technical Summary

Technical Problem

In the flattened state of existing foldable electronic devices, the angle between the door panel and the horizontal plane is large, resulting in a decrease in the quality of the screen light and shadow.

Method used

A rotating shaft mechanism is designed. By setting multiple connecting parts and limiting layers between the door panel and the arc arm, the door panel and the arc arm are fixedly connected to ensure that the door panel does not displace during the entire machine opening and closing process. By matching the limiting layers of different thicknesses, the angle between the door panel and the horizontal plane is adjusted to reach zero or close to zero.

Benefits of technology

It effectively reduces the angle between the door panel and the horizontal plane when the whole machine is in a flattened state, and improves the screen light and shadow quality in the folding axis area of ​​the electronic equipment.
