Problems solved by technology

[0006] First, the gold foil and the battery case are connected by spot welding, and the connection method of point contact is unstable, which may easily lead to the separation of the battery case and the gold foil, resulting in poor contact between the gold foil and the battery case;
[0007] Second, manufacturing the antenna assembly requires at least the following steps: placing the gold foil in place; and welding the gold foil and the battery case, which is a cumbersome process and inefficient;
[0008] Third, the cost of gold leaf is high

Embodiment Construction

[0042] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0043] Such as Figure 3 to Figure 5 As shown, the antenna assembly of the mobile terminal includes a metal shell 10 and an antenna pad 20. The metal shell 10 has an inner wall facing the inside of the mobile terminal and an outer surface facing the outside of the mobile terminal. The outer surface of the metal shell 10 can be directly used as a mobile The shell of the terminal can al...

Abstract

The present disclosure relates to a mobile terminal, an antenna assembly of the mobile terminal and a manufacturing method thereof. The antenna assembly of the mobile terminal includes a metal casing and an antenna pad, the metal casing is also used as an antenna, and the antenna pad is integrally formed with the metal casing through a 3D printing process. The technical solution provided by the present disclosure includes the following beneficial effects: first, the antenna pad is in surface contact with the metal shell, which is more firm and reliable than the point contact method in the prior art; second, the 3D printing process sprays liquid metal Alloy materials, directly print the antenna pads on the metal shell, compared with the spot welding process in the prior art, the operation is convenient and saves manpower; third, the metal alloy material replaces the gold in the prior art, saving materials cost.

Description

technical field [0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a mobile terminal, an antenna assembly of the mobile terminal and a manufacturing method thereof. Background technique [0002] The mobile terminal has an antenna assembly for sending and receiving signals. The antenna assembly generally includes an antenna and an antenna pad (also referred to as an antenna PAD). The antenna pad serves as a medium to connect the main board and the antenna. [0003] The following takes a mobile phone as an example to illustrate the technical solution of the antenna assembly of the existing mobile terminal. [0004] Such as figure 1 and figure 2 As shown, the metal battery case 100 of the mobile phone can function as an antenna. The metal battery case 100 (such as an aluminum alloy battery case) is welded with gold foil inside, and the gold foil serves as the antenna pad 200 . The gold foil is formed into a sheet struc...
