A hinge assembly attaches a cover pivotally to a base of an electronic device such as a notebook computer and has a base bracket, a pintle and a cover bracket. The base bracket is attached to the base and has a gudgeon. The pintle is mounted securely in the gudgeon in the base bracket. The cover bracket is mounted tightly and rotatably around the pintle and securely on the cover of the electronic device, allows the cover to pivot on the base and has a through ring and a pivoting gudgeon. The through ring is mounted tightly around the pintle and has an open slot to prevent the through ring and the pintle from wearing. The pivoting gudgeon is slightly narrower than the through ring, fastens the pintle to position the cover and has an open slot to prevent the pivoting gudgeon and the pintle from wearing.

What is claimed is: 1. A hinge assembly comprising a base bracket having a side surface; a distal end; and a gudgeon being formed coaxially in the distal end of the base bracket; a pintle being mounted securely in and protruding longitudinally from the distal end of the base bracket and having a proximal end; a distal end; and a mounting segment being formed on and protruding coaxially from the proximal end of the pintle and corresponding to and being mounted securely in the gudgeon in the base bracket; and a cover bracket being mounted rotatably and tightly around the pintle, abutting the distal end of the base bracket and having a proximal end; a distal end; a side surface; a through ring being formed on the proximal end of the cover bracket, corresponding to and being mounted tightly and rotatably around the pintle, abutting the distal end of the base bracket and having a sidewall; two ends; and an open slot being formed longitudinally through the sidewall of the through ring and communicating with the two ends of the through ring; and a pivoting gudgeon being slightly narrower than the through ring, being formed in the distal end of the cover bracket, being mounted tightly and rotatably around the distal end of the pintle, fastening the pintle and having a sidewall; two ends; and an open slot being formed longitudinally through the sidewall of the pivoting gudgeon and communicating with the two ends of the pivoting gudgeon. 2. The hinge assembly as claimed in claim 1, wherein the base bracket further has a leaf being formed on and protruding transversely from the side surface of the base bracket. 3. The hinge assembly as claimed in claim 1, wherein the cover bracket further has a leaf being formed longitudinally on and protruding transversely from the side surface of the cover bracket. 4. The hinge assembly as claimed in claim 1, wherein the gudgeon in the base bracket is keyed.
