INTERMITTENT LIFTING ASSEMBLY AND MOBILE TERMINAL

This application provides an intermittent lifting assembly and a mobile terminal. The intermittent lifting assembly is configured to drive a heat dissipation panel of the mobile terminal to open and close. The intermittent lifting assembly includes: a first driving piece that includes a first intermittent gear and a convex shoulder disposed on the first intermittent gear; a second driving piece that includes a second intermittent gear engaged with the first intermittent gear, where a position-limiting slot is disposed on the second intermittent gear, the position-limiting slot is configured to limit a position in which the convex shoulder rolls when teeth of the first intermittent gear and teeth of the second intermittent gear are out of an engaged state; and a gap for avoiding the second intermittent gear is disposed on the convex shoulder; and further includes a swing rod that is fastened to the second intermittent gear and configured to drive the heat dissipation panel to open or close. Intermittent movement of the first driving piece and the second driving piece improves linkage between the display screen and the heat dissipation panel when the mobile terminal is opened, and improves a use effect of the mobile terminal.
