Slide rail assembly

A slide rail assembly, comprising:

• a first rail;
• a second rail movable relative to the first rail;
• a third rail movable relative to the second rail, the third rail being arranged with a driving structure and a front contact feature;
• and
• a switch member movable relative to the second rail to be in one of a first state and a second state, wherein the switch member is arranged with a switch part;
• wherein the switch member is operable to switch from the first state to the second state;
• wherein the second rail is configured to be located at a predetermined position relative to the first rail;
• wherein when the second rail is located at a predetermined position relative to the first rail, and when the switch member is switched from the first state to the second state, the third rail is configured to drive the switch member to switch from the second state to the first state through the front contact feature during a process of the third rail being moved a predetermined extended distance relative to the second rail at the predetermined position along an extending direction;
• wherein when the second rail is located at a first extended position relative to the first rail, the switch member is operable to switch from the first state to the second state;
• wherein when the third rail is moved from a second extended position along a retracting direction and when the switch member is in the second state, the switch part of the switch member is configured to block a moving path of the driving structure, and the driving structure of the third rail is configured to continuously push the switch member in the second state along the retracting direction to drive the second rail to move to the predetermined position along the retracting direction.

A slide rail assembly, comprising:

• a first rail;
• a second rail movable relative to the first rail;
• a third rail movably mounted to a passage of the second rail to be movable relative to the second rail, the third rail being arranged with a driving structure and a rear contact feature;
• and
• a switch member movable relative to the second rail to be in one of a first state and a second state, wherein the switch member is arranged with a switch part;
• wherein when the third rail is detached from the passage of the second rail along an extending direction and when the switch member is switched from the first state to the second state, the third rail is configured to drive the switch member to switch from the second state to the first state through the rear contact feature during a process of the third rail being remounted to the passage of the second rail along a retracting direction;
• wherein when the second rail is located at a first extended position relative to the first rail, the switch member is operable to switch from the first state to the second state;
• wherein when the third rail is moved from a second extended position along the retracting direction and when the switch member is in the second state, the switch part of the switch member is configured to block a moving path of the driving structure, and the driving structure of the third rail is configured to continuously push the switch member in the second state along the retracting direction to drive the second rail to move to the predetermined position along the retracting direction.
