An electronic device includes separate housings, one includes a keyboard and the other includes a display screen, a pair of cam assemblies and a pair of actuator arms. Each cam assembly has first and second connection parts that are rotationally connected, and are configured so that the first and second connection parts tilt relative to each other responsive to rotation of one relative to the other. The first connection parts of both cam assemblies are connected to spaced apart locations on the first housing. The actuator arms are connected on one end to spaced apart locations on the second housing and are connected on the other end to different ones of the second connection parts of both cam assemblies. Relative movement of the first and second housings rotates the first connection part relative to the second connection part of both cam assemblies and tilts the first housing relative to the second housing.
