HOUSING AND METHOD FOR PROCESSING A HOUSING

1 . A method for processing a housing, the housing comprises a first surface, the first surface comprises a filler area with a first length, the method comprising:

providing a metal piece, wherein the metal piece comprises a groove and a second surface, the groove comprises a groove bottom, the groove bottom defines a recess extending through the groove bottom and the second surface, the recess has a second length, the second length is greater than or equal to the first length;

injecting filling liquid into the recess and the groove, the filling liquid solidified to form filler of the filler area; and

cutting the metal piece along the second surface to form the first surface of the housing.

2 . The method according to claim 1 , wherein a cutting thickness along the second surface is greater than or equal to a liner distance between the groove bottom and the second surface.

3 . The method according to claim 2 , wherein the cutting thickness along the second surface is smaller than a thickness of the metal piece.

4 . The method according to claim 1 , wherein the groove has a third length, a direction of the third length is parallel to a direction of the first length, the third length is greater than the first length.

5 . The method according to claim 1 , wherein the housing further comprises a third surface and a fourth surface, the third surface and the fourth surface are connected to opposite sides of the first surface, the filler comprises a first filling portion in the groove, along a direction of the second length, the first filling portion comprises opposite ends.

6 . The method according to claim 5 , further comprising:

cutting the second surface to expose the first filling portion; and

cutting the first filling portion on opposite ends to form the third surface and the fourth surface.

7 . The method according to claim 5 , wherein the first surface is a plane, the third surface and the fourth surface are curved surfaces.

8 . The method according to claim 1 , wherein a range of the first length is 1-6 millimeters.

9 . The method according to claim 1 , wherein a range of a width of the filler area is 0.5-5 millimeters.

10 . A housing comprising a first surface, the first surface comprises:

a filler area; and

a metal area positions on opposite sides of the filler area;

wherein the filler area is filled by filler, which comprises fibers, an arranging direction of at least one of the fibers is perpendicular to the first surface.

11 . The housing according to claim 10 , wherein a range of a length of the filler area is 1-6 millimeters, a range of a width of the filler area is 0.5-5 millimeters.

12 . The housing according to claim 10 , wherein the filler area is a plastic area, the filler is formed by solidifying injection liquid, the fibers are glass fibers.

13 . The housing according to claim 10 , wherein an arranging direction of at least 80% of the fibers is perpendicular to the first surface.

14 . The housing according to claim 10 , further comprising a third surface and a fourth surface, wherein the third surface and the fourth surface are connected to opposite sides of the first surface.

15 . The housing according to claim 14 , wherein the first surface is a plane, the third surface and the fourth surface are curved surfaces.
