In order to keep the antenna structure with good radiation performance under the condition of not additionally increasing the size of the electronic equipment, the antenna structure is installed on the outer surface of the middle frame to form the antenna component. The following description will be made in detail by taking an antenna assembly as an example.

Referring to fig. 6, fig. 6 is a schematic structural diagram of an antenna assembly according to an embodiment of the present application. Antenna assembly 50 may include an antenna structure 510 and an inlay 18, inlay 18 including a plastic rim 181 and inlay 182.

The inlay 182 may also be co-injection molded of metal and plastic. It should be noted that the plastic frame 181 may be integrally formed with the inlay 182, and will not be described herein.

Wherein, the outer surface of the outer periphery of the plastic frame 181 is provided with an antenna structure 510, and the antenna structure 510 is fixedly connected with the plastic frame 181. The side wall of the plastic frame 181 is provided with a mounting hole 1811.

In some embodiments, the antenna structure 510 may be disposed on an inner surface of the plastic frame 181, and the antenna structure 510 may be embedded inside the plastic frame 181. The free area between the antenna structure 510 and the components inside the electronic device is defined as an antenna clearance area, and since the antenna structure 510 is likely to interfere with the components inside the electronic device, the larger the antenna clearance area is, the less the interference of the components inside the electronic device with the antenna structure 510 is. However, the requirement of the appearance of the present electronic device is very high, and if the size of the electronic device is increased simply to increase the antenna clearance area, the appearance beautification of the electronic device is not facilitated, and the production cost is saved.

Set up antenna structure 510 at the peripheral surface of plastic frame 181, compare in setting up antenna structure 510 at the internal surface of plastic frame 181, under the condition that does not increase electronic equipment overall dimension, antenna structure 510 and the inside component of electronic equipment have kept away from the distance of a plastic frame 181 thickness at least, the distance of antenna structure 510 and the inside component of electronic equipment has been pulled open, increase the antenna headroom region undoubtedly, thereby make antenna structure 510 can not receive the influence of the inside component of electronic equipment, the performance of antenna structure 510 has been improved, the manufacturing cost of electronic equipment has been reduced.

In some embodiments, the inlay 18 has a first end and a second end, the first end and the second end being located at two opposite ends of the inlay 18, respectively, such as the first end being located at the top of the electronic device and the second end being located at the bottom of the electronic device.

Referring to fig. 7, fig. 7 is a schematic structural diagram of an antenna assembly according to an embodiment of the present application. The inlay 18 has four corners, namely a first corner 1, a second corner 2, a third corner 3 and a fourth corner 4, wherein the first corner 1, the second corner 2, the third corner 3 and the fourth corner 4 are respectively located at four corner positions of the plastic frame 181. Wherein the first corner 1 and the second corner 2 are located on both sides of the first end portion, respectively, and the third corner 3 and the fourth corner 4 are located on both sides of the second end portion, respectively.

The antenna structure 510 includes a first antenna structure 511, a second antenna structure 512, and a third antenna structure 513. The first antenna structure 511 is installed outside the plastic frame 181 and covers the first corner 1, the second antenna structure 512 is installed outside the plastic frame 181 and covers the second corner 2 and the first end portion, and the third antenna structure 513 is installed outside the plastic frame 181 and covers the third corner 3, the fourth corner 4 and the second end portion. Of course, the first antenna structure 511 and the second antenna structure 512 may form a complete antenna structure to cover the first corner 1, the second corner 2 and the first end portion. Of course, the first antenna structure 511 may also be arranged at the second end portion, with the third antenna structure 513 covering the first and second corners. The position relationship between the first antenna structure 511, the second antenna structure 512, and the third antenna structure 513 and the plastic frame 181 may be changed as needed, and will not be described herein in detail.

To further improve the protection of the antenna structure 510, in some embodiments, the antenna assembly 50 may further include a protection member 520 made of a non-metal material, and the protection member 520 may be made of a plastic material. The protection member 520 may be disposed on the outer surface of the plastic frame 181 and the outer surface of the antenna structure 510 to cover the antenna structure 510, such that the antenna structure 510 is located between the protection member 520 and the plastic frame 181. The number of the protection members 520 may be set according to the number of the antenna structures 510, for example, the protection members 520 include three protection members, namely, a first protection member 521, a second protection member 522, and a third protection member 523, where the first protection member 521 protects the first antenna structure 511, the second protection member 522 protects the second antenna structure 512, and the third protection member 523 protects the third antenna structure 513.

Therefore, by wrapping the protective member 520 around the periphery of the antenna structure 510, the antenna structure 510 is protected, the possibility of damage to the antenna structure 510 is reduced, the strength of the antenna structure 510 is increased, the possibility of deformation of the antenna structure 510 is reduced, and the signal strength of the antenna structure 510 is improved.

The antenna structure 510 is made of a metal material, such as a steel sheet, a copper sheet, or other metal or alloy material, and the specific material used for the antenna structure 510 is not limited in the embodiments of the present application. In the following embodiments, the antenna structure 510 is a steel plate for illustration, but not limitation, and the antenna structure 510 only uses a steel plate as the antenna structure 510.

Referring to fig. 8, fig. 8 is a schematic diagram of a first partial cross-sectional view of the antenna element shown in fig. 6. In some embodiments, the antenna assembly 50 may further include another antenna structure 550, where the antenna structure 550 includes an elastic clip portion 551 and a covering portion 552, and the elastic clip portion 551 is connected with the covering portion 552.

The coating portion 552 coats the outer surface of the plastic frame 181. A feed structure 555 extends from an inner surface of the antenna structure 550, and the feed point structure 555 is configured to be electrically connected to a circuit board.

The antenna structure 550 may be a steel plate, that is, the antenna structure 550 is formed by steel plates to transmit and receive signals. It should be noted that the thickness of the steel sheet is thin, for example, the thickness of the steel sheet is 0.1mm to 0.3mm, and further, the thickness of the steel sheet is 0.15mm to 0.2 mm. The steel sheet is easily deformed during the installation process, which affects the transmission and reception of signals by the antenna structure 550.

The antenna structure 550 is disposed on the outer surface of the periphery of the plastic frame 181, so that the clearance area of the antenna structure 550 can be increased and the radiation signal strength of the antenna structure 550 can be improved without changing the size of the electronic device. Meanwhile, the antenna structure 550 is embedded into the mounting hole 1811 of the plastic frame 181 through the elastic clamping portion 551, and when the antenna structure 550 is installed on the outer surface of the plastic frame 181, the elastic clamping portion 551 is only required to be embedded into the mounting hole 1811 from one side of the plastic frame 181, and is clamped and fixed in the mounting hole 1811 by using the elastic deformation of the elastic clamping portion 551, and then the coating portion 552 is coated on the outer surface of the plastic frame 181 until extending to the other side of the plastic frame 181 opposite to the elastic clamping portion 551. The connection of the antenna structure 550 and the plastic frame 181 does not need to adopt the injection molding process, the installation can be realized directly through the clamping of the structure, and the installation is very convenient. When the antenna structure 550 is damaged due to collision or falling, the elastic clamping portion 551 is pulled out of the mounting hole 1811, and the assembly and disassembly are also very convenient. Because the mounting and dismounting are very convenient, it is very convenient to replace when the antenna structure 550 is damaged.

Referring to fig. 9, fig. 9 is a second partial cross-sectional view of the antenna assembly of fig. 6. The elastic clamping portion 551 is disposed at the edge of the covering portion 552, the elastic clamping portion 551 and the covering portion 552 form an inclined clamping hook, and the direction of the mounting hole 1811 is adapted to the inclined direction of the clamping hook. It should be noted that the elastic clamping portion 551 and the covering portion 552 may form a hook with an angle of 45 degrees, and the elastic clamping portion 551 and the covering portion 552 may also form a hook with an angle of 60 degrees. It should be noted that the elastic clamping portion 551 and the covering portion 552 form a hook with an angle of 45 degrees, so as to better realize the clamping fixation of the antenna structure 550 and the plastic frame 181. It should be noted that the elastic clamping portion 551 may also form a hook perpendicular to the covering portion 552. The specific inclination angle of the hook formed by the elastic clamping portion 551 and the covering portion 552 is not limited in the embodiment of the present application.

In some embodiments, the resilient clip portion 551 is integrally formed with the cladding portion 552. Of course, the elastic clamping portion 551 and the covering portion 552 can be fixedly connected in other manners, for example, the elastic clamping portion 551 and the covering portion 552 can be connected in a welded manner.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view of a third portion of the antenna element shown in fig. 6.

Of course, the first elastic sheet 5511 and the second elastic sheet 5512 may also be connected by a connecting portion. The first elastic sheet 5511 and the second elastic sheet 5512 may form a U-shaped structure, and the first elastic sheet 5511 and the second elastic sheet 5512 may also form other structures.

Because the first elastic sheet 5511 and the second elastic sheet 5512 have a gap 5513 therebetween, an elastically deformed space is formed between the first elastic sheet 5511 and the second elastic sheet 5512. When the elastic clamping portion 551 is inserted into the mounting hole 1811, the first elastic sheet 5511 and the second elastic sheet 5512 are compressed inward, so that the first elastic sheet 5511 and the second elastic sheet 5512 are pressed into the mounting hole 1811. After the first elastic sheet 5511 and the second elastic sheet 5512 are pressed into the mounting hole 1811, the first elastic sheet 5511 and the second elastic sheet 5512 expand under the action of elastic force, so that the first elastic sheet 5511 and the second elastic sheet 5512 are clamped in the mounting hole 1811.

Referring to fig. 11, fig. 11 is a fourth partial cross-sectional view of the antenna assembly shown in fig. 6.
