ABSTRACT:
A housing assembly which comprises a primary housing, a secondary housing and a moving mechanism is provided. The primary housing has a first external contour and an opening disposed on the primary housing. The secondary housing has a second external contour. The moving mechanism connects the secondary housing to the primary housing so that the secondary housing can move between the sheltering position and the open position. When the secondary housing is located in the open position, the primary housing can define a space within the secondary housing. When the secondary housing is located in the sheltering position, the secondary housing is adapted to at least partially cover the opening. The first external contour and the second external contour together form a third external contour, which has substantially the same or different contour as the first external contour.
