Slide rail assembly

1 . A slide rail assembly, comprising:

a first rail comprising a first predetermined feature;

a first bracket device arranged on the first rail; and

a second bracket device movable relative to the first rail, the second bracket device comprising a locking member having a second predetermined feature;

wherein during a relative movement between the first rail and the second bracket device, the first predetermined feature of the first rail and the second predetermined feature of the locking member are configured to abut against each other, in order to move the locking member to switch from a locking state to an unlocking state;

wherein the first rail has a first end part and a second end part opposite to each other; wherein the first bracket device is arranged adjacent to the first end part, and the second bracket device is movable relative to the first rail to be away from the first end part;

wherein the first rail has a first side and a second side opposite to each other; wherein the slide rail assembly further comprises a reinforcing member attached to the first side of the first rail, and the reinforcing member is formed with a predetermined passage; wherein the second bracket device further comprises an extension frame movably mounted to the predetermined passage of the reinforcing member to be movable relative to the first rail along a longitudinal direction of the slide rail assembly; wherein the extension frame is arranged with an end plate, and the end plate is arranged with at least one mounting member, the locking member is pivotally connected to the extension frame through a shaft arranged in a height direction of the slide rail assembly to be rotatable relative to the extension frame around the shaft; wherein when the locking member is in the locking state, a locking part of the locking member is adjacent to the end plate with the locking member not being pressed by the first rail along a transverse direction of the slide rail assembly; wherein when the locking member is in the unlocking state, the locking part of the locking member is away from the end plate with the first predetermined feature of the first rail pressing the second predetermined feature of the locking member along the transverse direction of the slide rail assembly.

2 . The slide rail assembly of claim 1 , wherein one of the first predetermined feature of the first rail and the second predetermined feature of the locking member has a guiding part.

3 . The slide rail assembly of claim 1 , wherein the second bracket device further comprises an elastic feature configured to provide an elastic force to the locking member.

4 . The slide rail assembly of claim 1 , wherein the first rail comprises a first wall, a second wall and a longitudinal wall connected between the first wall and the second wall; wherein the first predetermined feature is adjacent to the first wall of the first rail.

5 . The slide rail assembly of claim 1 , wherein the first rail comprises a first wall, a second wall and a longitudinal wall connected between the first wall and the second wall; wherein the locking member comprises a first extension arm, a second extension arm and an operating part connected between the first extension arm and the second extension arm, and the operating part comprises the second predetermined feature; wherein the first extension arm and the second extension arm are adjacent to the first wall and the second wall respectively; wherein the first predetermined feature is arranged on the longitudinal wall of the first rail.

6 . A slide rail assembly, configured to be mounted to a rack comprising a first post and a second post, the slide rail assembly comprising:

a first rail comprising a first predetermined feature;

a first bracket device arranged on the first rail; and

a second bracket device, wherein the second bracket device and the first rail are movable relative to each other, the second bracket device comprises a locking member having a second predetermined feature;

wherein the first bracket device is configured to detachably mount the first rail to the first post, the second bracket device is configured to detachably mount the first rail to the second post, and the locking member in a locking state is configured to lock the second bracket device to the second post;

wherein during a process of the first rail being moved relative to the second bracket device along a predetermined direction with the first bracket device being detached from the first post, the first predetermined feature of the first rail and the second predetermined feature of the locking member are configured to abut against each other, in order to move the locking member to switch from the locking state to an unlocking state to no longer lock the second bracket device to the second post;

wherein the first rail has a first end part and a second end part opposite to each other; wherein the first bracket device is arranged adjacent to the first end part, and the second bracket device is movable relative to the first rail to be away from the first end part;

wherein the first rail has a first side and a second side opposite to each other; wherein the slide rail assembly further comprises a reinforcing member attached to the first side of the first rail, and the reinforcing member is formed with a predetermined passage; wherein the second bracket device further comprises an extension frame movably mounted to the predetermined passage of the reinforcing member to be movable relative to the first rail along a longitudinal direction of the slide rail assembly; wherein the extension frame is arranged with an end plate, and the end plate is arranged with a mounting member configured to be mounted to a mounting hole of the second post; wherein the locking member is pivotally connected to the extension frame through a shaft arranged in a height direction of the slide rail assembly to be rotatable relative to the extension frame around the shaft; wherein when the locking member is in the locking state, a locking part of the locking member is adjacent to the end plate with the locking member not being pressed by the first rail along a transverse direction of the slide rail assembly; wherein when the locking member is in the unlocking state, the locking part of the locking member is away from the end plate with the first predetermined feature of the first rail pressing the second predetermined feature of the locking member along the transverse direction of the slide rail assembly.

7 . The slide rail assembly of claim 6 , wherein one of the first predetermined feature of the first rail and the second predetermined feature of the locking member has a guiding part.

8 . The slide rail assembly of claim 6 , wherein the second bracket device further comprises an elastic feature configured to provide an elastic force to the locking member.

9 . The slide rail assembly of claim 8 , wherein the first bracket device comprises a mounting part configured to be mounted to a mounting hole of the first post.

10 . The slide rail assembly of claim 8 , further comprising a second rail located at the second side of the first rail and movable relative to the first rail.
