Hinge assembly and guide assembly for electronic devices using a heat carrying member

A hinge assembly comprising:

• a rotation mechanism to rotatably couple a first chassis to a second chassis of an electronic device;
• a guide unit including a first guide member, a second guide member, and guide end portions, wherein the guide end portions are configured to secure the first guide member and the second guide member in a fixed, spaced-apart orientation to define a passage area therebetween, the passage area sized to receive a middle portion of a heat carrying member, wherein the heat carrying member includes one end sized to be disposed in the first chassis and a second end sized to be disposed in the second chassis;
• an outer frame, the guide unit movably coupled to the outer frame;
• and
• a biasing member configured to move the guide unit away from the outer frame as the first chassis is rotated to a fully rotated position.

An electronic device comprising:

• a first chassis;
• a second chassis;
• a heat carrying member having one end disposed in the first chassis and a second end disposed in the second chassis;
• and
• a hinge assembly rotatably coupling the first chassis and the second chassis relative to each other, the hinge assembly including:
• an outer frame;
• a guide unit movably coupled to the outer frame and including a first guide member and a second guide member spaced to define a passage area therebetween, wherein a middle portion of the heat carrying member extends through the passage area of the guide unit between a first inner edge defining a first opening in the first chassis and a second inner edge defining a second opening in the second chassis;
• and
• means for maintaining a curve length of the middle portion of the heat carrying member at a substantially constant dimension when the first chassis is rotated relative to the second chassis, wherein the means for maintaining the curve length include:
• a cam configured to engage a portion of the guide unit;
• and
• a biasing member to bias the guide unit away from the outer frame when the first chassis is rotated relative to the second chassis in a first rotational direction.
