In some embodiments, the antenna structure 210 may be disposed on an inner surface of the frame 181, and may be embedded inside the frame 181, and a vacant area between the antenna structure 210 and components inside the electronic device is defined as an antenna clearance area, because the antenna structure 210 is likely to interfere with components inside the electronic device, so that the larger the area of the antenna clearance area is, the less interference on the antenna structure 210 is, however, the requirement on the appearance of the present electronic device is also very high, and if the antenna clearance is simply increased, the size of the electronic device is increased, which is not favorable for the appearance of the electronic device and the production cost.

The antenna structure 210 is fixedly connected to the frame 181 by disposing the antenna structure 210 on the outer surface of the periphery of the frame 181. Set up antenna structure 210 at the peripheral surface of frame 181, compare in the internal surface that sets up antenna structure 210 at frame 181, under the condition that does not increase electronic equipment overall dimension, antenna structure 210 has kept away from the distance of a frame 181 thickness at least, the distance of having pulled open antenna structure 210 and the inside electronic component of electronic equipment, increase the antenna clearance area undoubtedly, thereby make the antenna can not receive the influence of the inside component of electronic equipment, the performance of antenna is improved, the production cost of electronic equipment is reduced.

In other embodiments, the antenna assembly 20 may further include a protection member 220 made of a non-metal material, and the protection member 220 may be made of a plastic material. The protection member 220 may be disposed on the outer surface of the frame 181 and the outer surface of the antenna structure 210 to cover the antenna structure 210. So that the antenna structure 210 is positioned between the protective member 220 and the bezel 181. The number of the protection members 220 may be set according to the number of the antenna structures 210, for example, the protection member 220 has three, namely, a first protection member 221, a second protection member 222 and a third protection member 223, the first protection member 221 protects the first antenna structure 211, the second protection member 222 protects the second antenna structure 212, and the third protection member 223 protects the third antenna structure 213.

Therefore, the antenna structure 210 is wrapped on the surface of the antenna body or around the periphery of the antenna body 216 by the protection member 220, so that the antenna body 216 is protected, and the possibility of damage to the antenna body 216 is reduced; but also can increase the steel sheet intensity, reduce the possibility of antenna body 216 deformation, promote the signal intensity of antenna structure.

In the following embodiments, the antenna structure 210 uses a steel sheet as an example, but not limited to, and the antenna structure 210 only uses a steel sheet as the antenna structure 210.

As shown in fig. 3 to 5, the antenna structure 210 includes a steel sheet antenna 216a, and the steel sheet antenna 216a is attached to the outer surface of the periphery of the frame 181. The steel sheet antenna 216a is provided with a connecting piece 214, and the connecting piece 214 is fixedly connected with the frame 181.

In some embodiments, the connecting members are formed from the upper and lower edges of the frame 181 and are fixedly connected to the frame 181, the connecting members may be screws, the screws are in threaded connection with the frame 181, and the connecting members may also be buckles which are buckled into the frame 181 to realize fixed connection and other fixed connection modes.

Because the connection mode of adopting screw rod, buckle, need stretch into the deeper position of frame 181 with connecting piece 214, because connecting piece 214 adopts metal material usually in order to guarantee to connect length, when connecting piece 214 stretches into the inside overlength of frame 181, still can reduce the area of antenna headroom district, is unfavorable for antenna structure 210's use.

The connecting element 214 extends from the steel sheet antenna 216a to one side of the frame 181, and the connecting element 214 is connected to the frame 181, it can be understood that the connecting element 214 and the frame 181 are formed by injection molding, the frame 181 covers the frame 181, and the connecting element 214 is fixed inside the frame 181. Of course, the connecting member 214 and the protecting member 220 may be injection molded, the connecting member 214 is fixed inside the protecting member 220, and the protecting member 220 and the frame 181 are fixedly connected, wherein the fixing connection between the protecting member 220 and the frame 181 may be a threaded connection, or a pin may be used to fixedly connect the protecting member 220 and the frame 181, and the fixing connection between the protecting member 220 and the frame 181 is not limited to the above-mentioned manner, and is not described herein again.

Referring to fig. 6, in some embodiments, the antenna structure 210 includes an antenna body 216, the antenna body 216 includes a first edge 2161 and a second edge 2162 opposite to the first edge 2161, the first edge 2161 is an upper edge of the antenna body 216, the second edge 2162 is a lower edge of the antenna body 216, and at least one connector 214 is disposed on each of the first edge 2161 and the second edge 2162. It should be noted that, one connecting component 214, two connecting components 214, or even a plurality of connecting components 214 may be respectively disposed on the first side 2161 and the second side 2162, and the number of the connecting components 214 on the first side 2161 and the second side 2162 is not particularly limited. The connecting member 214 is disposed on the first side 2161 and the second side 2162 of the antenna body 216, so that the connection between the connecting member 214 and the frame 181 is more secure and is not easily loosened.

In some embodiments, when one side of the antenna structure 210 includes three or more connectors 214, the connectors 214 on the same side are uniformly arranged. The connection between the connecting members 214 and the frame 181 can be more uniform due to the uniform arrangement of the connecting members 214.

In some embodiments, the spacing between the

connectors

214 and 214 of the first edge 2161 is the same as the spacing between the

connectors

214 and 214 of the second edge 2162. The spacing between the connecting members 214 and the connecting members 214 on both sides of the antenna body 216 is the same, which makes the stress applied when the antenna body 216 is connected to the frame 181 more uniform. It is understood that the distance between the connecting element 214 and the connecting element 214 on both sides of the antenna body 216 need not be the same, and the distance between the connecting element 214 and the connecting element 214 can be set according to the requirement, which is not limited herein.

The shape of the clamping edge 402a is gradually widened from the outer surface of the glue drawing body 401a to the inner surface of the glue drawing body 401a, and gradually widened from the root of the glue drawing body 401a to the edge. By adopting the glue pulling position 400a with the shape, the frame 181 and the antenna structure can be fixed in the longitudinal direction and the transverse direction, so that the firmness of the frame 181 and the antenna structure 210 is improved.

Wherein, the connecting part 214 is gradually widened from the antenna body 216 to the extending direction of the frame 181. That is, the width of the connection position between the connecting member 214 and the frame 181 is wider, so that the connection position between the connecting member 214 and the frame 181 can be fixed at more positions, thereby improving the connection strength between the connecting member 214 and the frame 181.

One end of the connecting member 214 close to the frame is provided with a hook 2141. It should be noted that the hook 2141 is fixedly connected to the end portion of the connecting member 214 near the frame, or the antenna body 216 may be arc-shaped and extend toward the frame to form the hook 2141.

The hook 2141 is clamped into the frame, and the frame 181 covers the hook 2141. It should be noted that the hook 2141 and the frame 181 are molded together, so that the hook 2141 is clamped into the frame 181, and the frame 181 covers the hook 2141, thereby making the connection more secure. It should be noted that the hook 2141 does not engage with the inner surface of the frame 181, but is retracted from the inner surface of the frame 181. Thereby ensuring a sufficient antenna clearance area.

Referring to fig. 8, a feeding point structure 217 is disposed on the antenna body 216 toward the frame.
