Abstract

The disclosed are a mobile terminal, a housing therefor, and a method for manufacturing the housing. The housing includes a transparent main body formed integrally. The transparent main body has an outer surface and an inner surface opposite to each other and includes a flat plate portion and a side portion connected with each other, the side portion is disposed at a periphery of the flat plate portion, and a through hole is provided in the side portion. The outer surface of the transparent main body is provided with a light-shielding layer jointed with a side wall of the through hole. An orthographic projection area of the side wall of the through hole on a reference plane is located within an orthographic projection area of the light-shielding layer on the reference plane, and the reference plane is a geometric plane in parallel with the flat plate portion.

2. The housing according to claim 1 , wherein all the light-shielding layer is provided at the side portion; or
wherein one part of the light-shielding layer is provided at the flat plate portion and another part of the light-shielding layer is provided at the side portion.

3. The housing according to claim 1 , wherein a first transparent hardened layer is disposed on a part of the outer surface that is not provided with the light-shielding layer, a second transparent hardened layer is disposed on a side of the light-shielding layer that is away from the transparent main body, and the second transparent hardened layer is jointed with the first transparent hardened layer.

4. The housing according to claim 1 , wherein the through hole penetrates the inner surface and the outer surface along an extending direction of the through hole, an orthographic projection of the side wall of the through hole on an another reference plane defines a first contour line, the another reference plane is a geometric plane perpendicular to the extending direction, the reference plane and the another reference plane are perpendicular to each other; and
an orthographic projection of the light-shielding layer on the another reference plane defines an enclosed area, the enclosed area has an inner edge and an outer edge, the inner edge coincides with the first contour line, and the inner edge is located in an area enclosed by the outer edge.

5. The housing according to claim 4 , wherein an area enclosed by the inner edge is elliptical, oblong or circular, and the area enclosed by the outer edge is rectangular, oblong or elliptical.

6. The housing according to claim 1 , wherein a decorative layer is provided on at least a part of the inner surface, and the decorative layer is made of an opaque material.

7. The housing according to claim 1 , wherein the flat plate portion has a first surface and a second surface opposite to each other, the side portion has an inner peripheral surface and an outer peripheral surface opposite to each other, the first surface and the inner peripheral surface together form a part or all of the inner surface, the outer peripheral surface and the second surface are joined to form the outer surface, at least a part of the outer peripheral surface is an arc surface, and the through hole penetrates the arc surface.

8. The housing according to claim 1 , wherein a thickness of the light-shielding layer is in a range from 0.02 mm to 0.04 mm.

9. A method for manufacturing a housing, the housing being applicable to a mobile terminal, the method comprising:
providing a transparent main body, wherein the transparent main body has an outer surface and an inner surface opposite to each other, the transparent main body comprises a flat plate portion and a side portion connected with each other, and the side portion is disposed at a periphery of the flat plate portion and encloses the flat plate portion;
forming a light-shielding layer at the outer surface of the transparent main body; and
providing a through hole in the side portion, the through hole penetrating both the inner surface and the outer surface;
wherein the light-shielding layer is located around the through hole and an end of a side wall of the through hole that is away from the inner surface is connected to the light-shielding layer, an orthographic projection area of the light-shielding layer on a reference plane covers an orthographic projection area of the side wall of the through hole on the reference plane, and the reference plane is a geometric plane in parallel with the flat plate portion.

10. The method according to claim 9 , wherein the forming a light-shielding layer at an outer surface of the transparent main body comprises:
transferring, by a screen printing process, ink to the outer surface of the transparent main body, to form the light-shielding layer.

11. The method according to claim 9 , wherein the providing a transparent main body comprises:
integrally forming the transparent main body by an injection molding process with a transparent material.

12. The method according to claim 11 , wherein a cavity of a mold adopted for forming the transparent main body has raised gains, and the forming a light-shielding layer at the outer surface of the transparent main body comprises:
during the forming of the transparent main body with the mold, filling the transparent material into a recess formed between the raised gains to form the light-shielding layer at the outer surface of the transparent main body.

13. The method according to claim 12 , wherein a depth of the recess formed between raised grains is in a range from 0.01 mm to 0.05 mm.

14. The method according to claim 9 , wherein before the through hole is provided in the side portion, the method further comprises:
forming a decorative layer on the inner surface of the transparent main body, wherein the decorative layer is made of an opaque material.

15. The method according to claim 9 , wherein before the through hole is provided in the side portion, the method further comprises:
