Abstract

A shell is provided. The shell includes a metallic body, a non-metallic layer and a coating layer. The non-metallic layer is configured to connect at least two parts of the metallic body, and the coating layer is provided on an outer surface of the non-metallic layer, and exhibits a consistent color with an outer surface of the metallic body. A method for manufacturing the shell and the mobile terminal including the shell are also provided.

Claims (33)

1. A shell, comprising:

a metallic body,

a non-metallic layer configured to connect at least two parts of the metallic body, and

a coating layer only provided on an outer surface of the non-metallic layer, and exhibiting a consistent colour with an outer surface of the metallic body, wherein the coating layer comprises ink comprising metal particles and pigments.

2. The shell according to claim 1 , the metal particles being at least one of aluminum, silver, iron, titanium, and an alloy thereof.

3. The shell according to claim 2 , further comprising an ink protecting layer provided on the outer surface of the coating layer.

4. The shell according to claim 3 , wherein the ink protecting layer comprises ink with sandblasting resistance; the ink in the coating layer being exposure ink and the ink protecting layer comprises exposure ink; an outer surface of the ink protecting layer being a matte surface.

5. The shell according to claim 3 , wherein at least one of a plurality of the coating layers and a plurality of the ink protecting layers are laminated on the non-metallic layer.

6. The shell according to claim 1 , wherein the non-metallic layer is configured to form a clearance area for an antenna; the non-metallic layer comprises a non-signal-shielding material, a material of the non-metallic layer being any one of plastics, carbon fiber, an organic resin and glass fiber.

7. The shell according to claim 1 , wherein an anodic oxidation layer is provided on the outer surface of the metallic body, and exhibits a consistent colour with the coating layer.

8. The shell according to claim 7 , wherein an outer surface of the anodic oxidation layer is a sandblasted surface, the anodic oxidation layer being formed integrally with the metallic body, the metallic body comprising a material selected from aluminum, silver, stainless steel, aluminium alloy, titanium alloy, magnesium alloy and magnalium alloy.

9. The shell according to claim 1 , wherein the non-metallic layer and the metallic body are formed integrally.

10. The shell according to claim 1 , wherein the non-metallic layer is formed as at least one ultra-fine strap of the shell, the at least one ultra-fine strap has a plurality of slots spaced apart from each other, the metallic body comprises at least two metal plates and a plurality of metal straps separated by the plurality of slots, a width of the slot being in a range of 0.2 mm to 3.0 mm.

11. The shell according to claim 1 , wherein the shell comprises a back cover and a frame integrally formed with the back cover and formed at a bent peripheral edge of the back cover.

12. A mobile terminal, comprising

a shell comprising:

a metallic body,

a non-metallic layer configured to connect at least two parts of the metallic body, and

a coating layer only provided on an outer surface of the non-metallic layer, and exhibiting a consistent colour with an outer surface of the metallic body, wherein the coating layer comprises ink comprising metal particles and pigments;

a mainboard fixed in the shell; and

a functional component disposed on the mainboard.

13. A shell, comprising:

a metallic body,

a non-metallic layer configured to connect at least two parts of the metallic body, and

a coating layer provided on an outer surface of the non-metallic layer, and exhibiting a consistent colour with an outer surface of the metallic body,

wherein the non-metallic layer is formed as at least one ultra-fine strap of the shell, the at least one ultra-fine strap has a plurality of slots spaced apart from each other, the metallic body comprises at least two metal plates and a plurality of metal straps separated by the plurality of slots, a width of the slot being in a range of 0.2 mm to 3.0 mm.

14. The shell according to claim 13 , wherein the coating layer comprises ink comprising metal particles and pigments, the metal particle being at least one of aluminum, silver, iron, titanium, and an alloy thereof.

15. The shell according to claim 14 , further comprising an ink protecting layer provided on the outer surface of the coating layer.

16. The shell according to claim 15 , wherein the ink protecting layer comprises ink with sandblasting resistance; the ink in the coating layer being exposure ink and the ink protecting layer comprises exposure ink; an outer surface of the ink protecting layer being a matte surface.

17. The shell according to claim 15 , wherein at least one of a plurality of the coating layers and a plurality of the ink protecting layers are laminated on the non-metallic layer.

18. The shell according to claim 13 , wherein the non-metallic layer is configured to form a clearance area for an antenna; the non-metallic layer comprises a non-signal-shielding material, a material of the non-metallic layer being any one of plastics, carbon fiber, an organic resin and glass fiber.

19. The shell according to claim 13 , wherein an anodic oxidation layer is provided on the outer surface of the metallic body, and exhibits a consistent colour with the coating layer.

20. The shell according to claim 19 , wherein an outer surface of the anodic oxidation layer is a sandblasted surface, the anodic oxidation layer being formed integrally with the metallic body, the metallic body comprising a material selected from aluminum, silver, stainless steel, aluminium alloy, titanium alloy, magnesium alloy and magnalium alloy.
