Hinge assembly for mobile computing device

A method for manufacturing a hinge assembly for coupling a first housing part and a second housing part of a computing device, the method comprising:

• molding a hinge assembly to include a spring-loaded opening mechanism, the spring-loaded opening mechanism being configured to bias with a biasing torque the first housing part and the second housing part to rotate away from each other when the first housing part and the second housing part are in a closed face-to-face orientation;
• including a magnetic closure system in the mobile computing device, the magnetic closure system being configured to retain the first housing part and the second housing part in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism;
• and
• including a release actuator in the magnetic closure system, wherein
• actuation of the release actuator when the first housing part and the second housing part are in the closed face-to-face orientation permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing torque of the spring-loaded opening mechanism.

A hinge assembly for coupling a first housing part and a second housing part of a computing device, the hinge assembly comprising:

• a spring-loaded opening mechanism arranged in the hinge assembly, the spring loaded opening mechanism including:
• a first hinge body configured to be positioned in the first housing part, the first hinge body having a first spring arranged on a first pin;
• a second hinge body configured to be positioned in the second housing part, the second hinge body having a second spring arranged on a second pin;
• a harness configured to couple the first hinge body and the second hinge body, the harness having a first shaft and a second shaft;
• a first follower having a first end disposed in a recess formed in a first head of the first pin, and a second end engaged with a first cam formed on the first shaft of the harness;
• and
• a second follower having a first end disposed in recess formed in a second head of the second pin, and a second end engaged with a second cam formed on the second shaft of the harness, wherein
• when installed in a computing device, the hinge assembly is configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other upon release of a closure system that holds the first housing part and the second housing part in a closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism.
