  • Publication number: 20240068516
    Abstract: A slide rail assembly includes a first rail, a second rail, a slide assisting device, an elastic member and a working member. The second rail and the first rail are movable relative to each other. The elastic member is arranged on the second rail. During a process of the second rail being moved relative to the first rail along an opening direction, the working member is configured to contact the elastic member in an initial state in order to drive the slide assisting device to move along the opening direction to a predetermined position. When the slide assisting device is located at the predetermined position, the elastic member releases an elastic force through a predetermined space of the first rail, such that the elastic member is no longer in the initial state with the working member no longer contacting the elastic member.
