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: A folding mechanism comprises a first cam structure, a second cam structure, and an elastic part, wherein the elastic part is located between the first cam structure and the second cam structure; in a process of folding or unfolding the electronic device, there are deformations on the first cam structure and the second cam structure along the extension direction of the length of the folding mechanism, a deformation direction of the first cam structure is opposite to a deformation direction of the second cam structure; and a length of the elastic part changed during the process of the folding or unfolding the electronic device.
