Abstract: The electronic device includes a folding apparatus and a flexible display. The folding apparatus is configured to bear the flexible display. An elastic component of the folding apparatus may transfer an elastic force to the flexible display by using a housing of the folding apparatus. A force that is away from a main shaft and that is applied to the flexible display when the electronic device is in a flattened state is greater than a force that is away from the main shaft and that is applied to the flexible display when the electronic device is in a closed state.

Abstract: This application discloses a folding mechanism and an electronic device. The folding mechanism is applied to a housing apparatus of an electronic device, and is configured to connect two housings of the housing apparatus. The folding mechanism can form display accommodating space through automatic avoidance in a folding process, and a flexible display is accommodated in the display accommodating space, so that a folding action performed by the housing apparatus on the flexible display is stable, and a squeezing force is small. This helps reduce a risk that the flexible display is damaged due to excessive squeezing of the folding mechanism, and makes the flexible display more reliable.
