Slide rail assembly

A slide rail assembly, comprising:

• a first rail comprising an engagement feature;
• a second rail movable relative to the first rail;
• a third rail mounted between the first rail and the second rail;
• a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail;
• a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail;
• a synchronizing member meshed between the first meshing feature and the second meshing feature;
• a first driving device comprising a first base and a first elastic member;
• a locking device connected to the first base of the first driving device, the locking device comprising a locking part;
• a swing member movably connected to the second rail, wherein the first elastic member of the first driving device is configured to accumulate a first driving force in response to the swing member abutting against the locking part of the locking device, the first driving force is configured to drive the second furniture part to move from a retrieve position to an open position relative to the first furniture part;
• a second driving device mounted to the second rail, the second driving device comprising a second base, a capturing member and a second elastic member, wherein the capturing member is movably connected to the second base for capturing the engagement feature of the first rail;
• and
• a clutch device mounted between the first rail and the first base of the first driving device;
• wherein the clutch device is configured to block the first driving device along a predetermined direction, when the second rail is moved from the open position to the retrieve position, the swing member abuts against the locking part of the locking device and the second elastic member accumulates a second driving force, the second driving force is configured to drive the second rail to be retrieved relative to the first furniture part.

• a synchronizing member meshed between the first meshing feature and the second meshing feature;
• a first driving device comprising a first elastic member;
• a locking device connected to the first driving device, the locking device comprising a locking part, a guiding passage passing through the locking part, and a guiding member configured to generate a force toward the locking part;
• and
• a swing member movably connected to the second rail, and configured to move to abut against the locking part through the guiding passage;
• wherein the first elastic member of the first driving device is configured to accumulate a first driving force in response to the swing member abutting against the locking part;
• wherein when the swing member is disengaged from the locking part, the swing member is guided to the guiding passage by the guiding member of the locking device, and the first elastic member releases the first driving force to drive the second rail to move from a retrieve position to an open position relative to the first rail.
