Slide rail assembly

A slide rail assembly comprising:

• a first rail comprising a channel, a first predetermined feature and a blocking portion being located inside the channel;
• a second rail displaceable relative to the first rail;
• an aid-sliding device movably mounted between the first rail and the second rail;
• a resilient member arranged on the aid-sliding device, the resilient member comprising a second predetermined feature;
• an auxiliary member arranged on the second rail;
• a first working member movably mounted on the second rail;
• and
• a first releasing member;
• wherein when the second rail is located at an extended position relative to the first rail, the first working member blocks an end of the blocking portion for preventing the second rail from displacing away from the extended position in an opening direction;
• wherein the first releasing member is configured to operate the first working member to prevent the first working member from blocking the end of the blocking portion for allowing the second rail to displace away from the extended position in the opening direction;
• wherein during a process that the second rail is displaced relative to the first rail away from the extended position in the opening direction for a detachment of the second rail from the channel of the first rail in the opening direction, the auxiliary member contacts with the second predetermined feature of the resilient member to drive the aid-sliding device in the opening direction to reach a predetermined position;
• wherein the resilient member is switchable between a first state and a second state, the resilient member accumulates a resilient force when the resilient member is in the first state, when the aid-sliding device is located at the predetermined position, the second predetermined feature of the resilient member is located at a position corresponding to the first predetermined feature, such that the resilient member releases a resilient force to resiliently switch the resilient member from the first state to the second state in order to prevent the auxiliary member from contacting with the second predetermined feature of the resilient member for allowing the detachment of the second rail from the channel of the first rail in the opening direction.
