Abstract: A housing assembly includes a housing, a push button, and a sealing member. The housing includes a bottom plate and a sidewall protruding from the bottom plate. The sidewall defines an opening therethrough and includes a protruding tab protruding from an inner side thereof and extending around the opening. The push button includes a button body extending through the opening and a pushing portion protruding from an inner side of the button body. The sealing member is made of elastic material and includes a first surface and an opposite, second surface. The first surface defines a receiving groove, and the protruding tab is tightly fit in the receiving groove. When the push button is pressed, the pushing portion pushes the sealing member and the sealing member is elastically deformed, thereby preventing liquid from entering the housing through a gap between the push button and the housing.

Abstract: A sliding mechanism comprises a sliding plate, a main plate, a sliding enabling member, a biasing member and a stopping member. The sliding plate has sidewalls and the main plate has peripheral walls corresponding to the sidewalls, respectively. The slide enabling member is coupling the sidewalls to the peripheral walls such that the sliding plate is slid relative to the main plate between closed and open position. The biasing member provides a force for biasing the sliding plate to slide relative to the main body. The stopping member is coupled between the sliding plate and the main plate. When the sliding plate is slid from the open position to the closed position, the stopping member provides a mechanism for the sliding plate to steadily slide relative to the main plate and to firmly stop in the closed position.

Abstract: An elastic assembly for a portable electronic device includes at least two springs and two bushings. Each spring has a different curvature radius and two annular connecting portions at two ends, the connecting portion of each spring having a different diameter relative other connecting portion of other springs. The springs are substantially arranged in a plane, the two connecting portions of each spring are respectively coiled around and secured to another two connecting portion of another spring, the two bushings are respectively secured to the two connecting portion having the smallest diameter. The disclosure also discloses a slide mechanism using the elastic module.
