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: A transmitter device (400), a receiver device (900), and a wireless charging method are provided. The transmitter device (400) includes a signaling modulation module (420), an energy modulation module (430), and an antenna element (440). The signaling modulation module (420) is configured to generate a narrowband modulation signal that carries signaling. The signaling includes an indication for a correspondence between a first resource and the receiver device (900). The first resource is scheduled based on a pre-received charging request signal from the receiver device (900). The energy modulation module (430) is configured to perform amplitude and phase adjustment on the narrowband modulation signal based on the pre-received charging request signal, to form an energy transmission signal. The antenna element (440) is configured to transmit the energy transmission signal on the first resource, to charge one or more receiver devices (900).

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.
