Abstract: An air-cooled carrier of heat-generating electronic components includes a frame, a plate, and baffles. The plate coupled to the frame divides airflow in the frame into two channels. Opposite sides of each channel along a first direction carry inlet and outlet. A pair of baffles is coupled to each channel, each baffle comprises a mounting part, an arc-shaped elastic part, and a blocking part. The mounting part is fixed to the frame and the arc-shaped elastic part. The blocking part is fixed to the arc-shaped elastic part and extends to middle of the airflow cavity in a second direction perpendicular to the first direction. In the absence of a mounted storage component, the elastic part bringing the blocking part to a first position and so blocking air flow from that outlet to that inlet.

Abstract: A locking mechanism for mounting hard drive to rack includes a shell and a lock component. The lock component comprises a handle, a pin, a lever, a torsion spring, and a compression spring. When the handle is located on the inner position, the lever latches the handle, the torsion spring is compressed, the compression spring pushes the pin out of the shell to insert into a slot of the rack to lock the hard drive to the rack. When pressing the lever to unlatch the handle, the torsion spring pushes the handle rotate to the outer position, meanwhile the handle retracts the pin into the shell to unlock the hard drive from the rack. An electronic device structure and a server using the locking mechanism is also disclosed.

Abstract: A carrier tray to allow rapid installment of additional modules or devices, without screws, into a computer includes a frame, two sliders, an elastic member, and a handle. A bracket of the frame has a unit cavity. The two sliders can slide along a first direction and the elastic member is compressible between the two sliders. The handle allows pushing and pulling of the tray along a second direction and is attached to the two sliders, the two sliders can move towards each other (to a first position) or apart (to a second position). The two sliders return to the unity cavity by pulling the handle from the first position to the second position along the second direction. Continued pulling of the handle in the second direction removes the carrier tray from the computer.

Abstract: A warning structure includes a bracket and a warning member mounted on the bracket. The bracket includes a main body, rollers rotationally mounted to the main body, and a stopping assembly including a support member, a mounting member, and a resilient member. The support member is coupled to the main body. The mounting member is movably mounted to the support member. The rollers are mounted to the mounting member and the main body. The resilient member elastically resists the support member and the mounting member to bias the mounting member. When the support member is subjected to a downward force, the support member abuts against a ground to keep the bracket stationary.

Abstract: A self-applying braking apparatus to prevent wind-blown movement of a mobile device includes a main body, a resisting member, a retaining member, a pushing member, and a mounting member. The braking apparatus is mounted on an application device by the mounting member. The retaining member provides an elastic force to fix the main body on the application device. The resisting member is disposed on the main body and configured to abut the tarmac or ground to prevent the mobile device from moving. The pushing member is disposed on the main body and is configured to push the resisting member to abut the ground when blown by the wind or by turbulence from a passing vehicle in a predetermined direction, when greater than the elastic force. The braking apparatus prevents unwanted wind-blown movement.
