## Abstract

A machine case for accommodating at least one electronic device is provided. The machine case includes a top plate and a bottom plate. The bottom plate has a smooth arc surface, the smooth arc surface has a vertex, and a distance between the vertex of the smooth arc surface and the top plate is less than a distance between any other part of the smooth arc surface and the top plate. The smooth arc surface protruding towards the top plate is formed on the bottom plate of the machine case in advance, so that when an electronic device is placed on the bottom plate, the smooth arc surface becomes flat. A processing method of a machine case is further provided. The smooth arc surface is formed according to the deformation of the bottom plate when an electronic device is placed on the bottom plate.

## Claims

### Claim 1

A machine case, for accommodating at least one electronic device, comprising:
a top plate;
a plurality of side plates, wherein every two adjacent side plates are connected to each other, each side plate has a first side edge and a second side edge opposite to each other, and the first side edges are connected to the top plate; and
a bottom plate, connected to the second side edges, wherein the bottom plate has a smooth arc surface, the smooth arc surface has a vertex, and a distance between the vertex of the smooth arc surface and the top plate is less than a distance between any other part of the smooth arc surface and the top plate.

### Claim 2 (depends on 1)

The machine case according to claim 1, wherein the smooth arc surface occupies a part of the bottom plate.

### Claim 3 (depends on 1)

The machine case according to claim 1, wherein the smooth arc surface occupies an entirety of the bottom plate.

### Claim 4 (depends on 1)

The machine case according to claim 1, wherein the top plate, the side plates, and the bottom plate are formed integrally.

### Claim 5

A processing method of a machine case, wherein the machine case is used for accommodating at least one electronic device, and the processing method of the machine case comprises:
calculating a deformation of a bottom plate of the machine case when the at least one electronic device is placed on the machine case; and
fabricating a smooth arc surface according to the deformation, wherein the smooth arc surface has a vertex, and a distance between the vertex of the smooth arc surface and a top plate of the machine case is less than a distance between any other part of the smooth arc surface and the top plate of the machine case.

### Claim 6 (depends on 5)

The processing method of a machine case according to claim 5, wherein said fabricating the smooth arc surface comprises forming the smooth arc surface on a part of the bottom plate.

### Claim 7 (depends on 5)

The processing method of a machine case according to claim 5, wherein said fabricating the smooth arc surface comprises forming the smooth arc surface on all of the bottom plate.

### Claim 8 (depends on 5)

The processing method of a machine case according to claim 5, wherein the smooth arc surface is fabricated in the manner of stamping.
