Abstract

A portable electronic device has a cover, a base and a heat-dissipating hinge. The heat-dissipating hinge has a cam and a foot. The cam is attached to the cover. The foot abuts the cam and protrudes out of the base. When the cover is opened, the cam is rotated to push the foot protruding out of the base and standing on the table. Therefore the base is elevated to easily dissipate heat so heat dissipation efficiency of the portable electronic device is increased.

Claims

1. A heat-dissipating hinge comprising:

a stationary bracket;

a pintle connected securely to the stationary bracket;

a cam mounted rotatably around the pintle and having a lifting sector and a steady sector defined continuously on the cam, wherein a radius of the lifting sector is smaller than a radius of the steady sector; and

a foot selectively abutting periphery edges of the lifting and steady sectors of the cam.

2. The heat-dissipating hinge as claimed in claim 1, wherein

the radius of the steady sector of the cam is uniform;

and

the periphery edge of the lifting sector has a first end and a second end, the second end is connected to the periphery edge of the steady sector and the radius of the lifting sector is gradually increased from the first end to the second end.

3. The heat-dissipating hinge as claimed in claim 1, wherein the foot has a tag formed on a top surface of the foot and selectively abutting the periphery edges of the lifting and steady sectors of the cam.

4. The heat-dissipating hinge as claimed in claim 2, wherein the foot has a tag formed on a top surface of the foot and selectively abutting the periphery edges of the lifting and steady sectors of the cam.

5. The heat-dissipating hinge as claimed in claim 1 further comprising a resilient element having two springs, wherein

the foot has two extending wings formed respectively on two sides of the foot;

and

the springs respectively abut the extending wings.

6. The heat-dissipating hinge as claimed in claim 1 further comprising a torsion generating assembly mounted around the pintle.

7. The heat-dissipating hinge as claimed in claim 6, wherein the torsion generating assembly comprises

two positioning washers mounted around the pintle and having corresponding protrusions and detents;

and

at least one resilient disc mounted around the pintle and abutting one of the positioning washers.

8. A portable electronic device with at least one heat-dissipating hinge as claimed in claim 1 comprising

a base having a through hole formed through a bottom of the base;

a cover connected pivotally to the base;

the at least one heat-dissipating hinge mounted between the base and the cover;

the stationary bracket of each one of the at least one heat-dissipating hinge attached to the base;

the cam of each one of the at least one heat-dissipating hinge attached to the cover; and

the foot of each one of the at least one heat-dissipating hinge protrudes through the through hole of the base.

9. The portable electronic device as claimed in claim 8 further comprising a fan, wherein

the base has multiple elongated holes;

and

the fan is mounted in the base.

10. A portable electronic device with at least one heat-dissipating hinge as claimed in claim 5 comprising

a base having a through hole formed through a bottom of the base;

a cover connected pivotally to the base;

the at least one heat-dissipating hinge mounted between the base and the cover;

the stationary bracket of each one of the at least one heat-dissipating hinge attached to the base;

the cam of each one of the at least one heat-dissipating hinge attached to the cover;

the foot of each one of the at least one heat-dissipating hinge protrudes through the through hole of the base; and

the resilient element of each one of the at least one heat-dissipating hinge pressed between the foot and the base.

11. The portable electronic device as claimed in claim 10 further comprising a fan, wherein

the base has multiple elongated holes;

and

the fan is mounted in the base.
