An electronic device with an extraction device and an extraction device thereof are provided. The extraction device includes a housing and a handle. A front side of the housing has two ends. The two ends have a pivot and a limiting member, respectively. The limiting member has at least one limiting recessed portion that has a draw bar and a hook. Two ends of the draw bar have a long groove and a pulling and gripping portion, respectively. The pulling and gripping portion is connected to the hook, the pivot is disposed in the long groove, and the hook can engage in the at least one limiting recessed portion along a sliding direction to be in an engaged state. The handle in the engaged state can slide along an unlocking direction so to depart from the at least one limiting recessed portion to be in an unengaged state.

The ratcheting cam-latch includes a cam that is configured to rotate about a cam rotation-axis. The cam has a cam-in surface with a concave curvature configured to interface with a cam-in feature on a server rack. The cam-in surface has a decreasing radius from the cam rotation-axis in a first direction around the cam rotation-axis. The ratcheting cam-latch also includes a handle mount configured to rotate about a handle rotation-axis that is parallel to the cam rotation-axis and a ratchet disposed between the handle mount and the cam. The ratchet is configured to, responsive to a first rotational force on the handle mount in the first direction, cause the cam to turn in the first direction and, responsive to a second rotational force on the handle mount in a second direction that is opposite the first direction, not cause the cam to turn in the second direction.

An electronic device with an extraction device and an extraction device thereof are provided. The extraction device includes a housing and a handle. A front side of the housing has two ends. The two ends have a pivot and a limiting member, respectively. The limiting member has at least one limiting recessed portion that has a draw bar and a hook. Two ends of the draw bar have a long groove and a pulling and gripping portion, respectively. The pulling and gripping portion is connected to the hook, the pivot is disposed in the long groove, and the hook can engage in the at least one limiting recessed portion along a sliding direction to be in an engaged state. The handle in the engaged state can slide along an unlocking direction so to depart from the at least one limiting recessed portion to be in an unengaged state.

A locking mechanism for removably locking a first electronic component to a second electronic component includes a positioning post, a locking member, and a biasing member. The positioning post is adapted to be mounted on the second electronic component and has a neck. The locking member is adapted to be movably connected to the first electronic component, and includes an engaging portion and a trigger portion. The biasing member is disposed for biasing the locking member to retain the locking member in a locking position where the engaging portion is engaged with the neck. The trigger portion of the locking member is operable for driving the locking member to move away from the locking position to disengage the engaging portion from the neck and to deform the biasing member.

A detaching mechanism for a detachable module is provided. The detaching mechanism includes an engaging component and a driving component. The engaging component is for separately engaging with a positioning component. The engaging component is movable relatively to the detachable module along a first direction. The driving component is movable relatively to the detachable module along a second direction different from the first direction. When the driving component moves along the second direction, the driving component pushes the engaging component to move along the first direction, so as to drive the engaging component to disengage from the positioning component. An electronic device with the aforementioned detaching mechanism is also provided.

An electronic assembly and a chassis assembly, wherein the electronic assembly comprises a chassis, a riser card assembly, and a display card assembly. The riser card assembly comprises an assembly bracket and a riser card. The assembly bracket comprises a bracket body and a handle including two mount parts and a handheld part. The riser card is disposed on the bracket body. The display card assembly comprises a tray, a display card and a restriction cover. The display card is disposed on the tray and electrically connected to the riser card. The restriction cover is disposed on a side of the tray. The bracket body and the tray are slidably disposed on the chassis along different directions. When the tray is mounted on the chassis, the restriction cover covers the handheld part, thereby preventing the handle from allowing the bracket body to slide relative to the chassis.

A handle-equipped sliding rail assembly includes a handle body, a buckle having a front part located inside the handle body and a locking means located at the front end and disposed outside the handle body, and a switching member connected to the handle body and the buckle and movable relative to the handle body and the buckle between a first state where the switching member drives the buckle toward a first position and the locking means extends along with the buckle out of the handle body, and a second state where the switching member drives the buckle toward a second position and the locking means retracts along with the buckle into the inside of the handle body.

A computing device include a chassis, a mounting ear, a lever, and a locking unit. The chassis holds one or more electronic devices and is insertable into a rack, such as a server rack. The mounting ear is coupled to the chassis. The lever is rotatably coupled to the mounting ear and is rotatable between a first position and a second position. In the first position, the lever engages the rack to prevent the chassis from being removed. In the second position, the lever disengages the rack and allows the chassis to be removed. The locking unit is coupled to the mounting ear and transitions between locked and unlocked states. In the locked state, the locking unit secures the lever in the first position. In the unlocked state, the lever is movable from the first position to the second position.
