    Abstract: An expansion module is detachably assembled with a portable computer. The expansion module includes a plate member, a supporting plate, a deformable connecting member, and an expansion unit. The supporting plate is pivoted to the plate member to rotate relative to the plate member between an opened position and a closed position. When the supporting plate is in the closed position, the supporting plate and the plate member defines an accommodating space. The deformable connecting member is connected to the plate member. The expansion unit is connected to the plate member through the deformable connecting member. When the supporting plate is in the closed position, the expansion unit is rotated from a first position to a second position by bending the deformable connecting member and is stored in the accommodating space.
