Abstract

An embodiment of the present invention discloses a mobile terminal, which relates to the field of communications technologies and is invented to enable the mobile terminal to have relatively good metal texture and appearance. The mobile terminal includes a metal rear cover used as a grounding component and at least one antenna, where the antenna includes a grounding pin, and the grounding pin is electrically connected to the metal rear cover. The present invention is mainly applicable to mobile terminal products.

First claim

What is claimed is:

1. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component, the metal rear cover including a bezel disposed thereon, a first portion of the bezel being a metal material and a second portion of the bezel is a non-metallic material, and a thickness of the second portion is greater than a thickness of the first portion;
a printed circuit board, disposed between the display and the metal rear cover, including a reference ground disposed on the printed circuit board and electrically connected to the metal rear cover; and
at least one antenna including a grounding pin electrically connected at one end of the grounding pin to the reference ground of the printed circuit board and electrically connected at another end of the grounding pin to the first portion of the bezel that is the metal material.

2. The mobile terminal according to claim 1 , wherein the another end of the grounding pin is electrically connected to the first portion of the bezel by a first electric conductor.

3. The mobile terminal according to claim 1 , wherein
the printed circuit board further includes a radio frequency circuit disposed on the printed circuit board.

4. The mobile terminal according to claim 3 , wherein the at least one antenna further includes a feeding pin electrically connected to the radio frequency circuit.

5. The mobile terminal according to claim 1 , wherein the at least one antenna further includes an antenna component.

6. The mobile terminal according to claim 5 , wherein the antenna component is an independent metal component.

7. The mobile terminal according to claim 5 , wherein
the antenna component is partially or completely made up of a metal structural component of the bezel.

8. The mobile terminal according to claim 7 , wherein the antenna component is partially or completely made up of a part of the metal structural component of the bezel.

9. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component;
a printed circuit board, disposed between the display and the metal rear cover, including a reference ground disposed on the printed circuit board and electrically connected to the metal rear cover;
at least one antenna including a grounding pin electrically connected at one end of the grounding pin to the reference ground of the printed circuit board and electrically connected at another end of the grounding pin to the metal rear cover;
at least one other printed circuit board, disposed between the display and the metal rear cover, including another reference ground disposed on the at least one other printed circuit board and connected to the metal rear cover; and
at least one other antenna including another grounding pin electrically connected at one end of the another grounding pin to the another reference ground of the at least one other printed circuit board to electrically connect the at least one other antenna to the metal rear cover via the another grounding pin.

10. The mobile terminal according to claim 9 , wherein a bezel is disposed on the metal rear cover.

11. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component, the metal rear cover including a side bezel disposed thereon, a gap in a portion of the side bezel being embedded with a non-metallic material, and a remaining portion of the side bezel being a metal material;
a printed circuit board, disposed between the display and the metal rear cover, including a reference ground disposed on the printed circuit board and electrically connected to the metal rear cover;
at least one antenna including a grounding pin electrically connected at one end of the grounding pin to the reference ground of the printed circuit board and electrically connected at another end of the grounding pin to the metal rear cover;
wherein
the remaining portion of the side bezel includes a thin metal portion disposed adjacent to the gap in the portion of the side bezel embedded with the non-metallic material in a width direction of the side bezel,
the thin metal portion is electrically connected to the another end of the grounding pin, and
the thin metal portion has a thickness less than a thickness of the gap in the portion of the side bezel embedded with the non-metallic material.

12. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component, the metal rear cover including a bezel disposed thereon, a first portion of the bezel being a metal material, a second portion of the bezel being the metal material, and a third portion of the bezel, disposed between the first portion of the bezel and the second portion of the bezel, being a non-metallic material;
a printed circuit board, disposed between the display and the metal rear cover, including a reference ground disposed on the printed circuit board and electrically connected to the metal rear cover; and
at least one antenna including:
a grounding pin electrically connected to the reference ground of the printed circuit board, and
an antenna component including a first antenna wire electrically connected at one end of the first antenna wire to the first portion of the bezel disposed on the metal rear cover, and electrically connected at another end of the first antenna wire to the second portion of the bezel disposed on the metal rear cover.

13. The mobile terminal according to claim 12 , further comprising:
a parasitic component of the antenna component including a second antenna wire disposed spaced apart from the antenna component and electrically connected to the metal rear cover.

14. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component, the metal rear cover including a bezel disposed thereon, a first portion of the bezel being a metal material and a second portion of the bezel being a non-metallic material;
a printed circuit board, disposed between the display and the metal rear cover, including a reference ground disposed on the printed circuit board and electrically connected to the metal rear cover; and
at least one antenna including:
a grounding pin electrically connected to the reference ground of the printed circuit board, and
an antenna component including a first antenna wire electrically connected to the first portion of the bezel,

wherein a width of the second portion in a widthwise direction of the mobile terminal is less than a width of the first portion.

15. A mobile terminal, comprising:
a front side including a display;
a rear side including a metal rear cover used as a grounding component, the metal rear cover including a bezel disposed thereon, a first portion of the bezel being a metal material, a second portion of the bezel being a non-metallic material, and a third portion of the bezel being a non-metallic material and disposed between the first portion of the bezel and the second portion of the bezel;
