  • Patent number: 12126745
    Abstract: This application provides a foldable screen device. The foldable screen device in this application includes two frames that are jointly articulated with a rotating shaft assembly. The two frames may rotate around rotating shafts of the rotating shaft assembly to be closed or opened. The rotating shaft assembly includes a connection structure and hinges. The connection structure has a channel that passes through two opposite sides of the rotating shaft assembly, and an electrical connection line of the foldable screen device penetrates into the channel. Two ends of the electrical connection line are respectively connected to the two frames, and the hinges and the channel are located at different positions of the rotating shaft assembly in an axial direction. In this way, bending deformation generated by the electrical connection line when the foldable screen device is folded is relatively small, and connection reliability is high.

  • Patent number: 11720187
    Abstract: A touchpad assembly includes a baseplate, a support, and a balance bar. The baseplate includes a first plate body and a second plate body. The first plate body is higher than the second plate body in a thickness direction of the touchpad assembly, and the first plate body is configured to accommodate a battery of the electronic device. The support is disposed on a side of the baseplate, the balance bar is supported between the support and the baseplate, and is capable of rotating around a set fulcrum of the baseplate. The balance bar includes a main body portion and supporting portions. At least part of each of the supporting portions is located on the first plate body. An end of each of the supporting portions that extends away from the main body portion does not extend past a bottom surface of the first plate body in the thickness direction.

  • Publication number: 20180239402
    Abstract: The present disclosure provides a dual-shaft structure which comprises a first shaft, a second shaft being arranged beside the first shaft, and a slider. The first shaft has a protruding first stop pin. The second shaft has a protruding second stop pin. The slider includes a first spiral slot and a second spiral slot. In response to a rotation of the first shaft, the first stop pin travels along the first spiral slot to move the slider linearly along an axial direction of the first shaft. In response to the linear movement of the slider, the second shaft rotates with the first shaft through an interaction between the second spiral slot and the second stop pin.
