A door structure includes a main door having an opening defined therein. A first and second auxiliary doors are hingedly fitted in the opening. A first and second latches are movably mounted on one end portion of the first and second auxiliary doors and are detachably engaged in a first and second notches defined in the main door. A first and second transmission mechanisms are respectively mounted in the first and second auxiliary doors for controlling the first and second latches to be detachably engaged in the first and second notches. A first and second driving members are respectively mounted in the first and second auxiliary doors for driving the first and second transmission mechanisms. A linking rod is connected between the first and second driving members such that the first and second driving members are able to operate synchronously so as to detach the first and second latches from the first and second notches synchronously via the first and second transmission mechanisms respectively.
