1. A self-closing slide rail assembly with a deceleration mechanism, comprising:
a first rail; a second rail longitudinally displaceable relative to the first rail; a stop portion provided at the second rail; a self-closing mechanism mounted to the first rail such that, while the second rail is being retracted in a first direction from an extended position toward a retracted position relative to the first rail, the self-closing mechanism automatically moves the second rail back to the retracted position by means of the stop portion, the self-closing mechanism including: a housing; a movable member movably connected with the housing, the movable member including an actuating portion; and an elastic member for applying to the movable member an elastic force in the first direction; and the deceleration mechanism including: a base; a supporting member movably connected with the base, the supporting member having a portion corresponding to the movable member of the self-closing mechanism; and a deceleration spring for applying to the supporting member an elastic force in a second direction opposite the first direction, wherein the elastic force applied by the deceleration spring is less than the elastic force applied by the elastic member; wherein while the second rail is being so operated as to be displaced in the first direction from the extended position toward the retracted position with the actuating portion of the movable member being engaged with the stop portion, the movable member drives the supporting member in response to the elastic force applied by the elastic member such that, with the elastic force applied by the deceleration spring that is able to counteract the elastic force applied by the elastic member, the movable member automatically and slowly moves the second rail back to the retracted position; wherein the base includes a first longitudinal section; the first longitudinal section at least includes a first wall, a second wall, a front wall, a rear wall and a bottom wall extending between the first wall of the base and the second wall of the base; the first wall, the second wall, the front wall, the rear wall, and the bottom wall define a damping room; the supporting member further has a friction portion movably corresponding to the damping room of the base; and at least one of the first longitudinal section and the friction portion of the supporting member further includes a friction surface such that, when the supporting member is driven by the movable member, the friction portion of the supporting member is displaced relative to the damping room of the base and resistance is provided by the friction surface. |
