A portable electronic device structure includes a first body, a connection plate, and a second body. The connection plate, pivoted to the first body, has an interworking assembly. The second body, pivoted to the interworking assembly, rotates with respect to the connection plate. The connection plate pivotally rotates to an open position with respect to the first body, and enables the interworking assembly to drive the second body to displace in a direction away from the first body, so that the second body is actuated to rotate smoothly.
