Abstract: A stylus and an electronic device component are disclosed. The stylus includes a stylus rod and a detachable stylus tip at one end of the stylus rod, and further includes a first electrode, a second electrode, and a circuit board. The first electrode is disposed in the stylus tip. The second electrode is disposed on an inner wall of the stylus rod, or the second electrode is disposed on a fastener in the stylus rod, and the second electrode is electrically connected to the second circuit board. This increases a distance between the first electrode and the second electrode, and reduces coupling between the first electrode and the second electrode. The stylus in embodiments of this application resolves a problem that writing accuracy of the stylus is reduced because the two electrodes in the stylus are easily coupled.

Abstract: This application provides a stylus and an electronic device assembly. With a mainshaft and a pressure sensor assembly disposed in the stylus, one end of the mainshaft connected to a tip assembly, and the pressure sensor assembly fixed in a barrel assembly and touching the other end of the mainshaft, the tip assembly moves under a pressure and drives the mainshaft to move, the mainshaft transfers the pressure on the tip assembly to the pressure sensor assembly, and the pressure sensor assembly detects the pressure on the tip assembly. With a second electrode fitting around a signal board, the moving of the tip assembly can drive the first electrode and the second electrode to move synchronously so that relative positions of the second electrode and the first electrode remain unchanged, improving measurement accuracy of a tilt angle of the stylus relative to a touchscreen by the electronic device.

Abstract: A hinge mechanism is applied to-a protective case. A first rotating shaft assembly in the hinge mechanism is fixedly connected to a first portion of the protective case, and is further rotatably connected to a second portion of the protective case. A second rotating shaft assembly in the hinge mechanism is fixedly connected to the second portion of the protective case, and is further rotatably connected to a third portion of the protective case. When the second portion of the protective case rotates relative to the first portion of the protective case by using the first rotating shaft assembly, a transmission part that cooperates with both the first rotating shaft assembly and the second rotating shaft assembly is configured to drive the third portion of the protective case to rotate relative to the second portion of the protective case by using the second rotating shaft assembly.
