Abstract: The present disclosure provides a foldable mechanism of a mobile terminal and the mobile terminal. The foldable mechanism includes a soft support structure and a hard support structure embedded in the soft support structure. The foldable mechanism formed by the soft support structure and the hard support structure embedded in the soft support structure is used as a component for connecting a first housing and a second housing. When the mobile terminal is unfolded, the foldable mechanism formed by the soft support structure and the hard support structure is unfolded and turns into a flat structure connected to the first housing and the second housing. When the mobile terminal is folded, one side of the soft support structure away from the hard support structure shrinks inward. Therefore, the mobile terminal is prevented from having an abrupt exterior structure, and an exterior effect of the mobile terminal is improved.

Abstract: An electronic device includes a flexible screen, a support mechanism, and a screen holder. The flexible screen includes a deformation area. The support mechanism includes a door plate corresponding to the deformation area, and the door plate is provided with an avoidance slot facing the flexible screen. In an unfolded state, a holding part is at least partially filled between a holding plate and the door plate corresponding to a main shaft module in the avoidance slot. In a folded state, the holding part slides out of the avoidance slot, so that the deformation area of the flexible screen in the folded state can enter the avoidance slot. In the folded state, the holding part slides out of the avoidance slot to increase available space in the avoidance slot, so that the deformation area of the flexible screen enters the avoidance slot.

Abstract: A rotating shaft structure includes a damping component, a first shaft body and a second shaft body. A first limiting slot is disposed on a circumferential surface of the first shaft body. The damping component is located between the first shaft body and the second shaft body. The damping component includes one or more damping groups. Each damping group includes an elastic part and a first ball. The first ball abuts against the circumferential surface of the first shaft body by using elastic force of the elastic part. A second end of the elastic part is elastically connected to the circumferential surface of the second shaft body. In a rotation process of the first shaft body, the first ball rolls relative to the circumferential surface of the first shaft body and can be positioned in the first limiting slot.

Abstract: This disclosure relates to a folding module and a foldable electronic device. A first protrusion and a first sliding slot are provided between a drive portion and a first connection member. A second protrusion and a second sliding slot are provided between the drive portion and a second connection member. A first drive spring and a second drive spring press against the drive portion. In a process in which the first support member folds or unfolds relative to the second support member, folding or unfolding can be implemented provided that the first support member and the second support member rotate by a relatively small angle, so that a speed of folding or unfolding of the first support member relative to the second support member is increased.

Abstract: In a rotating shaft mechanism and a foldable mobile terminal, connecting rods and swing arms are rotatably connected to a main shaft assembly, and the swing arms and the connecting rods rotate around different axes, so that the swing arms and the connecting rods rotate and slide relative to each other. During folding, the connecting rods or the swing arms drive the two support plates to rotate towards each other, the support plates and the main shaft assembly enclose folding space for accommodating a flexible display of the mobile terminal in a folded state, so that the bending effect of the flexible display is improved, and two housings of the mobile terminal fit almost seamlessly in the folded state.

Abstract: A connection rod and a swing arm are separately rotatably connected to a primary shaft component, and an axis around which the swing arm rotates and an axis around which the connection rod rotates are different, so that the swing arm and the connection rod rotate and slide relative to each other. The swing arm or the connection rod drives a support plate to rotate, so that the primary shaft component and the support plates can encircle to form, when the mobile terminal is completely folded, space that accommodates a folded part of a flexible display.
