Abstract: This application provides a hinge assembly and a foldable electronic device. The hinge assembly includes a pivot mechanism and an elastic mechanism disposed on the pivot mechanism. One of the elastic mechanism and a rotation mechanism is fixed to the pivot mechanism, and the other of the elastic mechanism and the rotation mechanism is rotatably connected to the pivot mechanism. One of the elastic mechanism and the rotation mechanism is provided with a plurality of protrusions, and the other of the elastic mechanism and the rotation mechanism is provided with a plurality of grooves that match the plurality of protrusions. When the rotation mechanism rotates to a preset location, at least one of the plurality of protrusions is received by at least one of the plurality of grooves, and remaining protrusions in the plurality of protrusions are interposed between the elastic mechanism and the rotation mechanism.
