How is the mechanism of Galaxy Z Fold2 folding smartphone arranged?

A month ago, was presented a folding smartphone with a flexible screen Samsung Galaxy Z Fold2 One of the most interesting elements of the design of this device is a hidden hinge with a double cam mechanism CAM, which allows you to smoothly fold the device and fix it in several positions. In this case, the mechanism does not violate the laconic design of the smartphone.

The other day the manufacturer has published a video in which Samsung experts told how to create a swivel mechanism folding smartphone Galaxy Z Fold2.

The hinge is a design development, created for the model Galaxy Z Flip. Since the Z Fold2 case is larger, the developers got more freedom and designed the optimal configuration, coming to it through dozens of prototypes. The final version consists of more than 60 parts.

In principle, the mechanism consists of two parts with protrusions and a flat surface between them. When the device is folded and unfolded, the inclined surfaces of the protrusions are in contact with each other, and when it is unfolded – flat surfaces. In other words, the smartphone is held in position not only by magnets but also by the hinge structure.

The gaps to the left and right of the hinge, which are necessary for the device to fold and unfold, are closed by micro brushes with elastic bristles. They prevent dust and mote from getting inside the device. The following video will illustrate all this.
