Housing assembly, mobile terminal, and method for assembling housing assembly

A mobile terminal, comprising:

• a housing assembly comprising:
• a frame body comprising a bearing surface and a limiting surface located on an inner side of the frame body;
• a cover plate comprising a op surface and a bottom surface opposite the top surface, wherein the cover plate further comprises a side surface surroundingly coupled between she too surface and the bottom surface, wherein the side surface comprises a first side surface coupled to the top surface and a second side surface coupled to the bottom surface, and wherein the cover plate is installed on the inner side of the frame body;
• an adhesive disposed between the bottom surface and the bearing surface and between the second side surface and the limiting surface, wherein an accommodating space is located between the first side surface and the limiting surface;
• and
• a decorative ring disposed in the accommodating space and covering the bearing surface;
• and
• a touchscreen installed on the inner side of the frame body and coupled to the bottom surface.

A method for assembling a housing assembly, comprising:

• providing a frame body comprising an inner side on which a bearing surface and a limiting surface are disposed;
• dispensing an adhesive on the bearing surface;
• providing a cover plate that comprises a top surface, a bottom surface, and a side surface surroundingly coupled between the top surface and the bottom surface, wherein the side surface comprises a first side surface coupled to the top surface and a second side surface coupled to the bottom surface;
• installing the cover plate on the inner side of the frame body by fastening the bottom surface to the bearing surface using the adhesive, wherein the bottom surface presses a part of the adhesive to a clearance between the second side surface and the limiting surface, and wherein installing the cover plate on the inner side of the frame body forms an accommodating space between the first side surface and the limiting surface;
• installing a decorative ring in the accommodating space;
• and
• making the decorative ring cover the bearing surface.
