## Abstract

An electronic apparatus with improved heat dissipation comprises a first body with a first shell and a second shell, a second body, a coupling device and a linkage device. The first shell is pivotally connected to the second shell to form an accommodation space. The first shell can pivot relative to the second shell to enlarge the accommodation space and form an opening between the first shell and the second shell. The coupling device couples the second body and the second shell to pivot the second body relative to the second shell to expose or hide the first shell. The linkage device drives the first shell to pivot relative to the second shell. When the second body pivots relative to the second shell toward a first direction, the linkage device drives the first shell to pivot relative to the second shell toward a second direction opposite to the first direction.

## Claims

### Claim 1

An electronic apparatus with improved heat dissipation, comprising:
a first body with a first shell and a second shell, wherein the first shell is pivotally connected to the second shell to form an accommodation space, and the first shell is operable to pivot relative to the second shell and thus to ascend so as to enlarge the accommodation space and form an opening between the first shell and the second shell, wherein the first body further comprises a metal mesh, wherein the metal mesh is disposed along an inner side surface of the first shell and an inner side surface of the second shell, and the metal mesh is fastened on a bottom of the first shell;
a second body;
a coupling device pivotally connecting the second body and the second shell so as to pivot the second body relative to the second shell for exposing or hiding the first shell; and
a linkage device operable to drive the first shell to pivot relative to the second shell, wherein
when the second body pivots relative to the second shell toward a first direction, the linkage device drives the first shell to pivot relative to the second shell toward a second direction opposite to the first direction.

### Claim 2 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the first body is a main body of a notebook computer, and the second body comprises a screen of the notebook computer.

### Claim 3 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the first body further comprises a keyboard module, and the keyboard module is engaged with the first shell.

### Claim 4 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the linkage device is a bump, and the bump is formed on the coupling device.

### Claim 5 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the linkage device comprises a first gear and a second gear, wherein the first gear has a first guide rail and is disposed in the accommodation space, the second gear has a second guide rail and is fastened on the coupling device, and the first guide rail gears with the second guide rail.

### Claim 6 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the linkage device is a spring, and the spring is disposed in the accommodation space.

### Claim 7 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, wherein the first body further comprises a trough-shaped structure, and the trough-shaped structure is formed on the inner side surface of the second shell, wherein when the first shell pivots relative to the second shell to descend, the metal mesh is partially disposed in the trough-shaped structure, and when the first shell pivots relative to the second shell to ascend, the metal mesh covers the opening formed between the first shell and the second shell.

### Claim 8 (depends on 1)

The electronic apparatus with improved heat dissipation of claim 1, further comprising a magnetic force mechanism for assisting the second body to pivot relative to the first body so as to hide the keyboard module.

### Claim 9 (depends on 8)

The electronic apparatus with improved heat dissipation of claim 8, wherein the magnetic force mechanism comprises a magnet disposed in the first body and an iron plate disposed in second body.
