Information handling system dual axis mono-barrel hinge
A dual axis hinge assembly couples first and second hinges to each other with a central barrel and routes cables across hinge axles with cable channels formed in the axles. The dual axis hinge assembly rotationally couples information handling system housing portions to each other and routes cables between the housing portions distal the barrel by running the cables through a channel formed in each axle of one of the hinges with the cable entering one axle distal the barrel, routing through the axle to a position proximate the barrel, crossing the hinge to enter the other hinge axle proximate the barrel and routing though the other axle to exit distal the barrel.
1. An information handling system comprising:
a main housing portion;
a lid housing portion;
processing components disposed in the main housing portion that cooperate to process information;
a hinge rotationally coupling the main and lid housing portions, the hinge having first and second parallel axles coupled to each other by a synchronizing mechanism, the first and second axles each having an internal channel, the internal channel having an opening extending along one side between the synchronizing mechanism and an end of each axle, the opening formed to have a larger size proximate the synchronizing mechanism than at the end, the larger size providing for passage of a cable across the parallel axels, the hinge further having a connection plate coupled to each axle opposite the opening for coupling to the main housing portion or lid housing portion; and
a cable interfaced with the processing components in the main housing portion and routing through the hinge first and second channels to the lid housing portion.
2. The information handling system of claim 1 further comprising:
first and second hinges rotationally coupling the main and lid housing portions, each hinge having first and second parallel axles coupled to each other by a synchronizing mechanism, at least the first hinge having the first and second channels; and
a barrel coupling the first and second hinges to each other at the synchronizing mechanisms.
3. The information handling system of claim 2 wherein the cable comprises a graphics cable that connects a graphics controller in the main housing portion to a display in the lid housing portion.
4. The information handling system of claim 2 wherein the cable comprises an antenna cable that connects a radio in the main housing portion to a radio in the lid housing portion.
5. The information handling system of claim 2 wherein the second hinge has first and second channels formed in the first and second axles.
6. The information handling system of claim 2 wherein each hinge axle integrates with a connection plate, the connection plate joined to the axle with torsional reinforcement.
7. The information handling system of claim 2 wherein the first and second hinges rotate the main and lid housing portions 360 degrees relative to each other.
8. The information handling system of claim 2 wherein the synchronizing mechanisms comprise gears.
9. An information handling system hinge assembly comprising:
first and second hinges;
a barrel coupled at a first end to the first hinge and at a second end to the second hinge;
first and second axles extending from each of the first and second hinges and away from the barrel, each of the first and second hinges coordinating orientation of the associated axles during rotation of the hinge assembly;
a connection plate coupled to each axle and configured to couple to an information handling system housing; and
a cable channel formed in each axle, each cable channel having an opening extending from the axle end opposite the barrel towards the barrel, the opening having a larger size proximate the barrel, the cable channel routing one or more cables from the opposite end towards the barrel, the one or more cables extending between the first and second axles at the opening larger size proximate the barrel.
10. The information handling system hinge of claim 9 further comprising a cable routed into the cable channel of the first axle distal the first hinge, through the cable channel of the first axle to exit proximate the first hinge and into the second axle cable channel proximate the first hinge.
11. The information handling system hinge of claim 10 wherein the cable further routes through the second axle cable channel from proximate the first hinge to exit the cable channel distal the first hinge.
12. The information handling system hinge of claim 11 wherein the cable comprises a graphics cable.
13. The information handling system hinge of claim 10 wherein the cable comprises a coaxial cable.
