360 degree bi-stable dual pivot hinge

摘要

In one general aspect, a computing device includes a lid, and a base coupled to the lid by a hinge, the hinge including a bi-stable hinge part including a toggle pivot and a toggle link bar, and a barrel hinge part including a hollow shaft, at least one friction element surrounding a first portion of the hollow shaft, and a casing surrounding a second portion of the hollow shaft, the casing being connected to the toggle link bar. The computing device includes a first mounting tab connected to the toggle link bar and connected to the base, and a second mounting tab connected to the at least one friction element and connected to the lid. The barrel hinge part enables the at least one friction element to rotate about the hollow shaft causing the lid to rotate relative to the base.

1. A computing device comprising:
a lid; a base coupled to the lid by a hinge, the hinge including:
a bi-stable hinge part including a toggle pivot and a toggle link bar; anda barrel hinge part including a hollow shaft, at least one friction element surrounding a first portion of the hollow shaft, and a casing surrounding a second portion of the hollow shaft, the casing being connected to the toggle link bar; a first mounting tab being connected to the toggle link bar and being connected to the base; and a second mounting tab being connected to the at least one friction element and being connected to the lid, wherein the barrel hinge part enables the at least one friction element to rotate about the hollow shaft causing the lid to rotate relative to the base, the rotation being from a first position to a second position, wherein the bi-stable hinge part has two stable rotational positions and unstable rotational positions between the two stable rotational positions, wherein the bi-stable hinge part enables the toggle pivot to rotate causing the lid to rotate relative to the base, the rotation being from the second position to a third position, and wherein a diameter of the bi-stable hinge part is less than a diameter of the barrel hinge part.
