  • Publication number: 20250126730
    Abstract: A hinge mechanism and a foldable electronic device are provided. The hinge mechanism is disposed in a foldable electronic device. When one rotation portion of the foldable electronic device moves, the hinge mechanism drives the other rotation portion to move. The hinge mechanism includes a fastening support, a transmission assembly, two first transmission shafts, a clamping assembly, and a first elastic portion. The fastening support is configured to be fastened to a base of the foldable electronic device, and the fastening support is coupled to the first transmission shaft to limit relative positions of the first transmission shaft and the fastening support. The first transmission shaft is coupled to the clamping assembly and the first elastic portion. The first elastic portion provides an elastic force for the clamping assembly such that friction between the clamping assembly and the transmission assembly generates damping.

  • Publication number: 20250080633
    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.

  • Patent number: 12047521
    Abstract: This application provides a rotation shaft structure and an electronic device. The rotation shaft structure includes a main shaft assembly, and two folding assemblies. The folding assembly includes a rotation assembly, a support plate, and a housing mounting bracket. The rotation assembly is rotationally connected to the main shaft assembly. The support plate is rotationally connected to the housing mounting bracket and slidably connected to the rotation assembly. When two housing mounting brackets rotate toward each other, two support plates rotate in a same direction relative to the housing mounting brackets on corresponding sides, so that the two support plates and the main shaft assembly can form a triangle-like display accommodation space. When the electronic device is in a closed state, the display accommodation space can be used for accommodating a bent portion of the flexible display, so that the flexible display is not damaged by extrusion.

  • Publication number: 20240199813
    Abstract: A process is described herein for producing a low-volatile-matter organosilicon linear body. The process can include: removing chlorine ions from a dimethyl dichlorosilane hydrolysate, and reducing volatile matters at 180-280° C. and ?0.0955 to ?0.0998 MPa. The obtained organosilicon linear body can have volatile matters of less than 0.5%, a viscosity of 50-150 mm2/s and a content of chloride ions of lower than 1 ppm. The process can be widely applied to the production of organosilicon subsequent products such as low-ring-body-content 107 glue, low-ring-body-content amino silicone oil, low-ring-body-content methyl silicone oil, and low-ring-body-content vinyl silicone oil, and can meet requirements of the European Union on content limitations of ring bodies in a polymer.
