[0030] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments does not limit the priority order of the embodiments.

[0031] Please refer to Figures 1 to 3 The high-performance smart terminal antenna structure of the embodiment of the present application includes a terminal metal shell 1, a functional bracket 3 and a functional mainboard 6, wherein a metal middle frame 2 is provided on the terminal metal shell 1, and the metal middle frame 2 has a first design length La, the functional bracket 3 is connected to the terminal metal shell 1, and the functional mainboard 6 is connected to the terminal metal shell 1 and is located between the terminal metal shell 1 and the functional bracket 3, and a gold finger 4 and an LDS antenna 5 coupled with the metal middle frame 2 are provided on the functional bracket 3, and the LDS antenna 5 has a second design length Lb, and the gold finger 4 is located on the side of the functional bracket 3 facing the functional mainboard 6 and is electrically connected to the LDS antenna 5, and the functional mainboard 6 is provided with spaced-apart feeding point springs 7 and location springs 8, the feeding point springs 7 are interference fit with the inner wall of the metal middle frame 2, and the location springs 8 are in contact with the gold finger 4.

[0032] During the specific implementation process, the high-performance smart terminal antenna structure improves the radiation efficiency and gain of the antenna through the coupling design of the metal middle frame 2 with a first design length La and the LDS antenna 5 with a second design length Lb, especially in applications in the 2.4GHz and Sub-6GHz frequency bands.

[0033] Among them, the interference fit between the feeding point spring piece 7 and the inner wall of the metal middle frame 2 ensures the stability of the electrical connection and reduces the risk of poor contact and signal loss. Here, the interference fit is based on the elastic structural characteristics of the feeding point spring piece 7. The feeding point spring piece 7 acts on the inner wall of the metal middle frame 2 through a certain elastic pressure or extrusion, so that the feeding point spring piece 7 is tightly fitted with the inner wall of the metal middle frame 2, thereby achieving reliable mechanical and electrical connection.

[0034] In addition, the contact between the location spring 8 and the gold finger 4 ensures the electrical connection between the LDS antenna 5 and the functional main board 6, effectively reducing the signal transmission loss and improving the signal transmission efficiency. By stacking the functional bracket 3 and the functional main board 6 on the terminal metal shell 1, the internal structure of the terminal metal shell 1 is optimized, so that the limited space is utilized more efficiently, that is, while ensuring performance, it will not occupy too much internal space of the terminal metal shell 1.

[0035] Specifically, the terminal metal shell 1 has a bearing surface 1 a , and the functional mainboard 6 and the functional bracket 3 are stacked in sequence on the bearing surface 1 a .

[0036] In one embodiment, an LDS routing area 9 is provided on the side of the functional bracket 3 close to the metal middle frame 2, and the gold finger 4 and the LDS antenna 5 are both located in the LDS routing area 9. It should be noted that the LDS routing area 9 is a precision routing area formed on the functional bracket 3 by the LDS (Laser Direct Structuring) process. Compared with the traditional antenna printed circuit board (PCB) routing, it is faster. Specifically, a preset routing path can be engraved on the surface of the functional bracket 3 by laser, and then the routing path is metallized (copper plating, nickel plating or gold plating) to form a preset circuit structure, and the LDS can be routed on a three-dimensional curved surface, that is, the LDS routing area 9 can cover different planes or curved surfaces of the functional bracket 3, thereby ensuring the electrical connection between the gold finger 4 and the LDS antenna 5, that is, making full use of the effective space of the functional bracket 3, expanding the effective area of ​​the antenna, and optimizing the clearance requirements of the antenna structure.

[0037] Preferably, the functional bracket 3 is provided with a connecting hole 10 in the LDS wiring area 9, and the gold finger 4 is electrically connected to the LDS antenna 5 through the connecting hole 10, thereby optimizing the wiring path and optimizing the clearance requirement of the antenna structure.

[0038] In one embodiment, the metal middle frame 2 is a monopole antenna and the LDS antenna 5 is a parasitic antenna. Specifically, the metal middle frame 2 as a monopole antenna can utilize the natural conductive properties of the terminal metal shell 1 to efficiently radiate electromagnetic waves, and provide stable signal coverage while having good radiation symmetry. It is particularly suitable for wireless communications in the 2.4GHz and Sub-6GHz frequency bands. As a monopole antenna, the metal middle frame 2 can be effectively integrated on the terminal metal shell 1 without taking up additional space, making the overall device design more compact and optimizing the antenna clearance requirements.

[0039] And, as a parasitic antenna, the LDS antenna 5 can enhance or adjust the directivity and gain of the signal by utilizing the radiation characteristics of the metal frame through the coupling with the metal middle frame 2. In an application scenario, the LDS antenna 5 formed on the functional support 3 by the LDS laser direct forming technology can adjust the length, shape or position of the antenna as needed to further optimize the coupling effect with the metal middle frame 2, so as to adapt to more complex wireless communication environment.

[0040] In a preferred embodiment, the first design length La of the metal middle frame 2 includes 22mm, and the second design length Lb of the LDS antenna 5 includes 5mm. It should be noted that, based on the high-performance smart terminal antenna structure of the present application, the design length of 22mm of the metal middle frame 2 has a significant advantage for signal propagation of 2.4GHz and Sub-6GHz frequency bands, which can effectively support signal radiation of multiple frequency bands while meeting the size requirements of a monopole antenna, and the design length of 5mm of the LDS antenna 5 can better perform precise electromagnetic coupling with the metal middle frame 2, thereby improving the antenna performance. That is, the cooperation of the two makes the antenna system have strong frequency band adaptability, can effectively save space, and not only ensures the performance of wireless signals, but also enables the device to remain light and efficient.

[0041] Further, the metal middle frame 2 and the LDS antenna 5 have a preset adjustment distance Lc, and the preset adjustment distance Lc includes 2mm. The 2mm spacing helps to optimize the interaction between the metal middle frame 2 as a monopole antenna and the LDS antenna 5 as a parasitic antenna, while ensuring the electromagnetic coupling effect and avoiding possible electromagnetic interference, so that the electromagnetic field distribution of the LDS antenna 5 and the metal middle frame 2 remains in an optimal state, enhancing the transmission efficiency of the antenna signal and improving the antenna performance.

[0042] In an embodiment, at least one break 11 is formed on the terminal metal shell 1, and the break 11 is located at the end of the metal middle frame 2. Specifically, the break 11 is formed on the terminal metal shell 1, especially at the end of the metal middle frame 2, which can effectively adjust the radiation mode of the antenna. The provision of the break 11 helps to reduce the closing effect of the metal middle frame 2, thereby improving the radiation efficiency of the antenna. In addition, the provision of the break 11 at the end of the metal middle frame 2 helps to reduce the reflected signals and electromagnetic interference generated by the terminal metal shell 1, ensuring the quality of the antenna signal.

For other working principles and processes of the electronic device of the present embodiment, refer to the foregoing description of the high-performance smart terminal antenna structure of the present embodiment, which will not be repeated here.
