摘要
A computing device is secured in an enclosure by a locking mechanism. The locking mechanism includes a jaw, a transmission lever, and an arm. The jaw is configured to abut a portion of the enclosure for holding the computing device. The transmission lever includes an arm pivot at one end and an actuating pivot at the opposite end. The arm is configured to rotate open and closed about the arm pivot and be selectively decoupled from the transmission lever. When the arm is coupled to the transmission lever, opening the arm causes the transmission lever to rotate open about the actuating pivot. Rotating open the transmission lever about the actuating pivot releases the jaw from the portion of the enclosure, and allows the computing device to be removed from the enclosure.

This application is a divisional of U.S. application Ser. No. 16/808,555, filed Mar. 4, 2020, the entirety of which is incorporated herein by reference.
The present disclosure relates to locking mechanisms for computing devices housed in enclosures.
Large scale users of computing devices, such as data center operators, typically mount computing devices in rack enclosures with standardized dimensions and/or connection points. Computing devices, such as network switches and routers, often adopt a modular design due to high development costs, large data transmission demands, and the need for installation flexibility as business requirements change. Typical network element devices have one engine module and several service modules (e.g., Fast Ethernet (FE), Gigabit Ethernet (GE), optical interface, etc.) based on the needs of the network element. Such modules typically employ multiple connectors to connect functionally to a backplane or other card. Each connector in a module requires a certain mating/unmating force, and as high density contact connectors are deployed, installing and removing the module may require a great force. Additionally, modules are tightly inserted in chassis slots for reliable operation and regulatory compliance, such as to reduce electromagnetic emissions. In practice, an ejector/locking mechanism using the principle of the lever is typically installed at each end of the module to assist with installation and removal of the module.

What is claimed is:1. A system comprising:a computing device configured to be mounted in an enclosure; and a locking mechanism coupled to the computing device, the locking mechanism comprising:a jaw configured to abut a portion of the enclosure; a transmission lever comprising an arm pivot at a first end and an actuating pivot at a second end; an arm configured to rotate about the arm pivot in an opening direction and a closing direction, the arm being selectively decoupled from the transmission lever; and a wedge configured to bias against the jaw and lock the jaw against the portion of the enclosure when the arm rotates in the closing direction, wherein when the arm is coupled to the transmission lever, rotating the arm in the opening direction causes the transmission lever to rotate in the opening direction about the actuating pivot and releases the jaw from the portion of the enclosure, enabling the computing device to be removed from the enclosure, wherein the transmission lever includes an unlocking slope configured to contact an unlocking surface on the wedge, wherein rotating the arm in the opening direction when the arm is coupled to the transmission lever releases the jaw from the portion of the enclosure by forcing the unlocking slope of the transmission lever against the unlocking surface of the wedge. 2. The system of claim 1 , wherein the locking mechanism further includes a slider to selectively decouple the arm from the transmission lever, enabling the arm to rotate separately from the transmission lever when decoupled. 3. The system of claim 2 , wherein the locking mechanism further includes a pin coupled to the slider, and wherein the arm pivot of the transmission lever includes an actuating slot configured to capture the pin when the slider couples the arm to the transmission lever. 4. The system of claim 3 , wherein the arm pivot further includes a detente angularly spaced from the actuating slot, the detente configured to bias the arm away from the computing device when the pin engages the detente. 5. The system of claim 4 , wherein the arm pivot includes a plurality of angularly spaced detente features configured to bias the arm in a plurality of angularly spaced positions. 6. A system comprising:a computing device including a plurality of ports on a front face of the computing device; and a locking mechanism on the front face of the computing device, the locking mechanism comprising:a jaw configured to secure the computing device in an enclosure; a transmission lever comprising an arm pivot at a first end and an actuating pivot at a second end; an arm configured to rotate about the arm pivot away from the plurality of ports, the arm being selectively decoupled from the transmission lever; and a wedge configured to bias against the jaw and lock the jaw against the enclosure when the arm rotates towards the plurality of ports, wherein when the arm is coupled to the transmission lever, rotating the arm away from the plurality of ports causes the transmission lever to rotate about the actuating pivot and release the jaw from the enclosure, enabling the computing device to be removed from the enclosure, wherein the transmission lever includes an unlocking slope configured to contact an unlocking surface on the wedge, wherein rotating the arm away from the plurality of ports when the arm is coupled to the transmission lever releases the jaw from the enclosure by forcing the unlocking slope of the transmission lever against the unlocking surface of the wedge. 7. The system of claim 6 , wherein the locking mechanism further includes a slider to selectively decouple the arm from the transmission lever, enabling the arm to rotate separately from the transmission lever when decoupled. 8. The system of claim 7 , wherein the locking mechanism further includes a pin coupled to the slider, and wherein the arm pivot of the transmission lever includes an actuating slot configured to capture the pin when the slider couples the arm to the transmission lever. 9. The system of claim 8 , wherein the arm pivot further includes a detente angularly spaced from the actuating slot, the detente configured to bias the arm away from the computing device when the pin engages the detente. 10.
