Abstract

An electronic apparatus includes a first chassis having a heat generating element, a second chassis, a hinge device that connects the first chassis and the second chassis such that the first chassis and the second chassis can be rotated relative to each other between a 0-degree attitude and a 180-degree attitude, and a display provided across the first chassis and the second chassis. The hinge device has a metal hinge main body, a metal first support plate provided to be relatively movable with respect to the inner surface of the first chassis, and a metal second support plate provided to be relatively movable with respect to the inner surface of the second chassis. The electronic apparatus further includes a flexible heat conductive member in the first chassis. The heat conductive member thermally connects a heat receiving member that receives heat from a heat generating element, and the first support plate.

Claims (33)

1. An electronic apparatus comprising:

a first chassis in which a heat generating element is mounted;

a second chassis adjacent to the first chassis;

a hinge device that connects the first chassis to the second chassis such that the first chassis and the second chassis can be rotated relative to each other between a 0-degree attitude, at which the first chassis and the second chassis are stacked to overlap each other in a surface normal direction, and a 180-degree attitude, at which the first chassis and the second chassis are both arranged in a direction perpendicular to a surface normal direction; and

a display having a fold region that is across the first chassis and the second chassis and is folded as the first chassis and the second chassis rotate relative to each other,

a first plate stationarily affixed to the display;

a second plate stationarily affixed to the display;

wherein the hinge device has:

a metallic hinge main body that extends along adjacent end portions of the first chassis and the second chassis, and that stretches across the adjacent end portions;

a metallic first support plate that extends along the adjacent end portions on an inner surface side of the first chassis, is connected to the hinge main body in a relatively rotatable manner, is pivotally connected to the first plate, is relatively movable with respect to the inner surface of the first chassis, and supports a back surface of the display between the 0-degree attitude and the 180-degree attitude; and

a metallic second support plate that extends along the adjacent end portions on an inner surface side of the second chassis, is connected to the hinge main body in a relatively rotatable manner, is pivotally connected to the second plate, is relatively movable with respect to the inner surface of the second chassis, and supports the back surface of the display between the 0-degree attitude and the 180-degree attitude,

the electronic apparatus further comprising a flexible heat conductive member inside the first chassis, and

the flexible heat conductive member thermally connecting a heat receiving member, which receives heat from the heat generating element, to the first support plate.

2. The electronic apparatus according to claim 1 ,

wherein the first support plate supports the display by a front surface thereof, and

the heat conductive member is connected to a back surface of the first support plate.

3. The electronic apparatus according to claim 2 ,

wherein the heat conductive member is composed of a graphite sheet.

4. The electronic apparatus according to claim 3 ,

wherein the graphite sheet has:

a first end portion fixed to the back surface of the first support plate,

a second end portion fixed to the heat receiving member, and

a central portion between the first end portion and the second end portion, and curved between the back surface of the first support plate and the heat receiving member.

5. The electronic apparatus according to claim 2 ,

wherein the heat conductive member is composed of a rubber material having thermal conductivity.

6. The electronic apparatus according to claim 2 ,

wherein the heat conductive member is composed of a member formed by wrapping a heat conductive sheet around an outer peripheral surface of a sponge material.

7. The electronic apparatus according to claim 2 ,

wherein the second support plate supports the display by a front surface thereof,

the electronic apparatus further including a sheet-like member that has thermal conductivity, and extends from the back surface of the first support plate to a back surface the second support plate.

8. The electronic apparatus according to claim 7 , further including:

a flexible second heat conductive member in the second chassis,

wherein the second heat conductive member thermally connects the second support plate and the second chassis.
