The present disclosure provides an electronic device. Fig. 1 is a schematic view of a partial cross-sectional structure of an electronic device according to an exemplary embodiment of the present disclosure, as shown in fig. 1, the electronic device 1 includes an antenna module 11 and a device body 12, the antenna module 11 is assembled to the device body 12, the antenna module 11 includes a radiation body 111, a metal structural member 112, and a feeding circuit, the radiation body 111 includes a feeding point and a first connection point 1111, and the feeding circuit is electrically connected to the feeding point. The metallic structural member 112 includes a second connection point 1211, and the first connection point 1111 is conductively connected to the second connection point 1211.

The antenna module uses the metal structural member 112 and the radiating body 111 to be connected in a conductive manner to serve as a radiator, and when the metal structural member 112 is connected to the radiating body 111 from the second connection point 1211, the bandwidth and the antenna performance of the antenna in the corresponding frequency band can be improved. The antenna performance is improved by adopting the mode, and the influence on the whole structure, appearance, thinness and screen occupation ratio of the electronic equipment 1 can be avoided while the antenna performance is considered.

In some embodiments, the device body 12 includes a key assembly 121, where the key assembly 121 includes the metal structural member 112, and at least a portion of the metal structural member 112 is exposed to the device body 12. Since the antenna module 11 uses the metal structural member 112 of the key assembly 121 and the radiating body 111 to be electrically connected together as a radiator, based on the radiation performance of the metal structural member 112 exposed out of the device body 12, when the metal structural member 112 is connected to the radiating body 111 from the second connection point 1211, the bandwidth and the antenna performance of the antenna in the corresponding frequency band can be improved.

Since the metal structural member 112 of the key assembly 121 is insulated from the middle frame during the assembly process, the metal structural member 112 can be prevented from being disturbed. The insulation between the metal structural member 112 and the middle frame may be that an insulation gap is formed between the metal structural member 112 and the middle frame, i.e. the metal structural member 112 is in a suspended state relative to the middle frame. The metal structural member 112 and the middle frame may be insulated, and the middle frame may include a mounting structure made of an insulating material, and the metal structural member 112 is assembled and matched with the mounting structure.

It should be noted that, the above-mentioned key assembly 121 includes a volume key assembly 121 and/or a shutdown key assembly 121, and the setting range of the second connection point 1211 can be increased by the length of the volume key assembly 121, so as to further improve the bandwidth and performance of the antenna at more frequencies. The metal structural member 112 of the shutdown key assembly 121 may also be electrically connected to the radiating body 111 to serve as a radiator. When the shutdown key assembly 121 and the volume key assembly 121 are jointly used for being connected with the same radiation main body 111, resonance formed by excitation of the metal structural member 112 in the frequency band can be expanded, and when the shutdown key assembly 121 and the volume key assembly 121 are jointly used for being connected with different radiation main bodies 111, the bandwidth and the antenna performance of the antenna in different frequency bands can be improved.

In some embodiments, as shown in fig. 1, 5, and 9, the metal structural member 112 includes a first end 1213, a second end 1214, and an intermediate section 1212 between the first end 1213 and the second end 1214, the second connection point 1211 is disposed at least one of the first end 1213, the second end 1214, and the intermediate section 1212, and by changing the location of the second connection point 1211, the feed path of the feed point to the metal structural member 112 may be changed, thereby exciting the formation of different resonances.

For example, the second connection point 1211 may be disposed at the middle section 1212, with the second connection point 1211 equidistant from both ends of the metallic structural member 112. Alternatively, the second connection point 1211 may be disposed at the first end 1213 or the second end 1214, and the second connection point 1211 is located at an edge position of the metal structural member 112. The equal distance between the second connection point 1211 and the two ends of the metal structural member 112 may mean that the distance between the second connection point 1211 and the two ends of the metal structural member 112 is substantially equal, and the distance between the second connection point 1211 and the two ends of the metal structural member 112 may be understood to be substantially equal within a certain error range. The location of the second connection point 1211 at the edge of the metal structural member 112 may mean that the second connection point 1211 is located substantially at the edge of the metal structural member 112, and that the distance between the second connection point 1211 and the edge of the metal structural member 112 is within a certain error range may mean that the second connection point 1211 is located at the edge of the metal structural member 112.

For example, as shown in fig. 1-4, the middle section 1212 of the metal structure 112 is in communication with the radiating body 111, and the second connection point 1211 is equidistant from the two ends of the metal structure 112. The metal structure 112 excites a 3.8G resonance alone, and the 3.8G resonance has high efficiency, and can be combined with the resonance of the antenna radiating body 111 itself to form a W wave as shown in fig. 4, thereby improving the antenna bandwidth and antenna performance. As shown in fig. 5 to 8, for example, the first end 1213 of the metal structure 112 is connected to the radiation body 111 at a position lower than the middle of the metal structure 112, and the second connection point 1211 is located at an edge of the metal structure 112. The metal structural member 112 can excite a 3.9G resonance, and the 3.9G resonance has high efficiency, and can be combined with the resonance of the antenna radiating body 111 to form a W wave as shown in fig. 8, thereby improving the antenna bandwidth and the antenna performance. As shown in fig. 9 to 12, a second end 1214, which is located above the middle of the metal structural member 112, is in communication with the radiation body 111, and a second connection point 1211 is located at an edge of the metal structural member 112. The metal structural member 112 can independently excite a 3.3G resonance, and the 3.3G resonance has higher efficiency, and can be combined with the resonance of the antenna radiating body 111 to form a W wave as shown in fig. 12, thereby improving the antenna bandwidth and the antenna performance.

In some embodiments, the apparatus body 12 includes a first assembly space inside the metal structural member 112, and the radiation body 111 is disposed in the first assembly space. The radiation main body 111 for radiating the antenna signal with the preset frequency band is arranged in the first assembly space, so that the connection difficulty between the metal structural member 112 and the radiation main body 111 can be reduced, and interference to other components or electronic components of the electronic equipment 1 is avoided. The number of the radiating bodies 111 in the first assembly space may be one, two or more, and may be set according to specific antenna requirements and the size of the first assembly space, so as to avoid interference between other modules such as a power module and a motherboard of the electronic device 1.

In some embodiments, the antenna module 11 includes a plurality of radiating bodies 111, the device body 12 includes a first assembly space located inside the metal structural member 112 and a second assembly space located outside the first assembly space, at least one radiating body 111 is disposed in the first assembly space, and at least one radiating body 111 is disposed in the second assembly space. The resonance of the antenna in other frequency bands can be further expanded by conducting the radiating body 111 positioned at other positions in the device body 12 to the metal structural member 112, so that the overall bandwidth and performance of the antenna are improved.

The second assembly space may be adjacent to the end of the metal structural member 112, so as to reduce the connection difficulty between the metal structural member 112 and the radiation body 111, and avoid interference between other components or electronic elements of the electronic device 1.

In some embodiments, the device body 12 may include a metal bezel, and the radiation body 111 includes at least a part of the structure of the metal bezel. That is, at least a part of the structure of the metal middle frame is used as the radiation body 111, so as to form a radiation scheme using the metal middle frame as an antenna radiator, thereby being beneficial to improving the radiation performance of the antenna and reducing the space occupation of the antenna module 11.

In other embodiments, the apparatus body 12 includes a metal base frame and a middle frame body injection molded to the metal base frame, and the radiation body 111 includes at least a part of the structure of the metal base frame. Namely, the metal base frame of the middle frame formed by in-mold injection molding is used as an antenna radiator, and the metal structural member 112 of the key assembly 121 is connected with the metal base frame to be used as the radiator, so that the bandwidth of the antenna is expanded, and the performance of the antenna is improved.

In some embodiments, the antenna module 11 further includes conductive connections electrically connected to the first connection point 1111 and the second connection point 1211, respectively. The first connection point 1111 and the second connection point 1211 are electrically connected by the conductive connection member, and the setting flexibility and the connection reliability of the first connection point 1111 and the second connection point 1211 are improved.

The conductive connecting piece can be made of elastic materials, the elastic materials can deform along with the pressing of the keys, and the deformation is recovered when the pressing force disappears, so that the influence on the key operation handfeel is avoided.

Specifically, the conductive connecting member may be conductive foam, conductive silica gel, or the like, which is not limited in this disclosure. The conductive connection members may be respectively connected with the radiating body 111 and the metal structural member 112 by means of bonding, welding, clamping, etc., which is not limited by the present disclosure.
