Slide rail assembly

A slide rail assembly, comprising:

• a first rail;
• a second rail longitudinally movable relative to the first rail;
• a first auxiliary member movably mounted to one of the first rail and the second rail, the first auxiliary member comprising a first guiding structure and a second guiding structure;
• and
• a second auxiliary member mounted to the other one of the first rail and the second rail, the second auxiliary member comprising a first guiding feature and a second guiding feature;
• wherein during a process of the second rail being moved relative to the first rail from a first predetermined position along a first predetermined direction with the first auxiliary member being located at a first working position, the first guiding structure of the first auxiliary member and the first guiding feature of the second auxiliary member are configured to contact each other in order to reduce speed of the second rail relative to the first rail along the first predetermined direction;
• wherein when the second auxiliary member crosses the first auxiliary member, the second rail is movable relative to the first rail to a second predetermined position;
• wherein during a process of the second rail being moved relative to the first rail from the second predetermined position along a second predetermined direction opposite to the first predetermined direction with the first auxiliary member being located at the first working position, the second guiding structure of the first auxiliary member and the second guiding feature of the second auxiliary member are configured to contact each other in order to reduce speed of the second rail relative to the first rail along the second predetermined direction;
• wherein during a process of the second rail being moved relative to the first rail from the second predetermined position along the second predetermined direction with the first auxiliary member being located at a second working position different from the first working position, the second guiding structure of the first auxiliary member does not contact with the second guiding feature of the second auxiliary member.
