[0080] Figure 1 1 is a schematic diagram of the structure of an electronic device of this embodiment. The electronic device includes but is not limited to a mobile phone, a watch or a tablet computer, etc. The outline of the radiation pattern 11 in the figure is shown by a dotted line.

[0081] Figure 2 The electronic device in the figure includes a receiving frame 7 and a first shielding plate 61 , a second shielding plate 62 , a substrate 51 , a circuit board 52 , a back plate 41 , a camera assembly 2 and a radiation unit 1 .

[0082] Figure 3 It is a schematic structural diagram of the camera assembly 2 and the radiation unit 1 of this embodiment. Figure 4 2 is an exploded schematic diagram of the camera assembly 2 of this embodiment. The camera assembly 2 in both figures includes three lens modules 22.

[0083] Figure 5 Schematic diagram of the positional relationship between the frame 31 and the radiation pattern 11 of this embodiment. Figure 6 yes Figure 5 Schematic cross-sectional view at AA in the middle. Figure 3-Figure 5 The radiation pattern 11 in is shown with a thick solid line.

[0084] In some embodiments, Figure 1-6 As shown, in this embodiment, the electronic device includes a radiation portion 1 and a camera assembly 2. The radiation portion 1 includes a radiation pattern 11, and the camera assembly 2 includes a fixing portion 21 and a lens module 22. The fixing portion 21 includes a fixing hole 211 and a metal fixing member 3 surrounding the fixing hole 211, and the fixing hole 211 fixes the lens module 22. At the same time, at least part of the metal fixing member 3 is arranged corresponding to at least part of the radiation pattern 11, and the metal fixing member 3 is coupled with the radiation pattern 11 to generate an induced current.

[0085] Specifically, in this embodiment, the metal fixing member 3 and the radiation pattern 11 maintain a predetermined distance (eg Figure 6 L1 in the figure), that is, the distance between the metal fixture 3 and the radiation pattern 11 cannot be too large, so that the metal fixture 3 can be coupled with the radiation pattern 11. At the same time, it can also reduce or even avoid mutual interference between the radiation pattern 11 and other radio frequency components in the electronic device.

[0086] In summary, the electronic device of this embodiment uses the cooperation between the metal fixing member 3 and the fixing hole 211 to fix the lens module 22, and at the same time couples the radiation part 1 with the metal fixing member 3. Therefore, the metal fixing member 3 can not only fix the lens module 22, but also generate an induced current on the metal fixing member 3 to cooperate with the radiation part 1 to conduct the guided electromagnetic wave. The working frequency band of the radiation part 1 is broadened, and the radiation efficiency of the radiation part 1 is increased.

[0087] In some embodiments, Figure 1-6 As shown, the electronic device further includes a shell 4. The fixing portion 21 further includes an insulating fixing member 23, and the insulating fixing member 23 is provided with a fixing hole 211. The metal fixing member 3 includes a frame 31, and the insulating fixing member 23 is fixedly connected to the shell 4 through the frame 31. The insulating fixing member 23 in this embodiment can fix the lens module 22, and the insulating fixing member 23 is configured to be unable to conduct electromagnetic waves. In this way, it is possible to avoid short-circuiting the metal fixing member 3, so that the metal fixing member 3 cannot generate an induced current.

[0088] Furthermore, if Figure 4 and Figure 6 As shown, the insulating fixing member 23 is a sheet structure, and the fixing hole 211 passes through the insulating fixing member 23. The radiation part 1 and the fixing part 21 are respectively arranged on both sides of the shell part 4, and in the thickness direction of the sheet structure, the frame 31 and the radiation pattern 11 partially overlap.

[0089] Specifically, the insulating fixing member 23 is made of glass. The glass material can increase the light collected by the camera assembly 2. At the same time, glass has a high resistivity and can also avoid changing the direction of the electromagnetic wave guided in the frame 31.

[0090] In this embodiment, the metal fixing member 3 is arranged on the outside of the shell 4 to facilitate fixing the filter 221 of the lens module 22. In this form, the metal fixing member 3 and the radiation pattern 11 are respectively located on both sides of the shell 4. In order to ensure that the guided electromagnetic waves on the radiation pattern 11 can be coupled to the metal fixing member 3, in this embodiment, part of the metal fixing member 3 and part of the radiation pattern 11 are arranged correspondingly to reduce the distance between the metal fixing member 3 and the radiation pattern 11.

[0091] In some embodiments, Figure 3-6As shown, the radiation pattern 11 includes a strip radiator 111. The number of lens modules 22 is multiple and arranged at intervals. The frame 31 includes a blocking body 32, and the blocking body 32 includes two first blocking bars 321. The multiple lens modules 22 are located between the two first blocking bars 321. The two first blocking bars 321 extend along a straight line and the length direction is consistent with the arrangement direction of the multiple lens modules 22 and the length direction of the strip radiator 111.

[0092] Specifically, in this embodiment, a plurality of lens modules 22 are arranged at intervals along a straight line, and the extension direction of the two first baffles 321 and the extension direction of the strip radiator 111 are parallel to the above straight line. When the guided electromagnetic wave is transmitted on the strip radiator 111, the parallel arrangement of the strip radiator 111 and the first baffle 321 can easily couple the electromagnetic signal between the two. As a result, the return loss of the radiation pattern 11 is improved, and the radiation efficiency of the antenna in the electronic device is increased.

[0093] In some embodiments, Figure 3-6 As shown, the radiation pattern 11 further includes a sheet radiator 112. The sheet radiator 112 has a feeding point 113, and one end of the strip radiator 111 is connected to the sheet radiator 112. In the axial direction of the lens module 22, part of the strip radiator 111 overlaps with a part of a first stop bar 321.

[0094] Figure 7 Schematic diagram of the conduction of the guided electromagnetic wave in the frame 31 of this embodiment. Figure 8 Schematic diagram of the conduction of the guided electromagnetic wave in the radiation pattern 11 of this embodiment. Figure 7 and Figure 8 As shown, the arrows in the figure are the guided electromagnetic waves transmitted on the radiation pattern 11 and the frame 31. The guided electromagnetic waves on the strip radiator 111 are transmitted from the sheet radiator 112 to the strip radiator 111, and are transmitted along the length direction of the strip radiator 111. In contrast, the transmission direction of the induced guided electromagnetic waves on the first baffle 321 corresponding to the strip radiator 111 is opposite to the transmission direction of the guided electromagnetic waves on the strip radiator 111. The guided electromagnetic waves are induced guided electromagnetic waves generated by the electromagnetic induction of the guided electromagnetic waves on the strip radiator 111 on the first baffle 321. As a result, the radiation efficiency of the radiation unit 1 is improved.

[0095] It is easy to understand that the above-mentioned effect can also be achieved by providing a parasitic branch coupled with the strip radiator 111 at a position adjacent to the strip radiator 111. However, the parasitic branch needs to be provided on the circuit board together with the radiating part 1. Therefore, the internal space of the electronic device is increased. At the same time, the difficulty of arranging the shielding plate is also increased. For this reason, the present embodiment improves the performance parameters of the radiating part 1 without adding new radio frequency devices.

[0096] In some embodiments, Figure 5-8 As shown, the sheet radiator 112 is a rectangular sheet with unequal lengths of adjacent sides. The extension direction of the strip radiator 111 is perpendicular to the long side of the rectangular sheet and connected to one long side of the rectangular sheet. One short side of the rectangular sheet is aligned with one long side of the strip radiator 111, and the other short side of the rectangular sheet is away from the enclosure 32. Thus, it is convenient for the guided electromagnetic wave to be conducted along the side where the strip radiator 111 is aligned with the sheet radiator 112, thereby increasing the coupling effect between the radiation pattern 11 and the first baffle 321.

[0097] In some embodiments, Figure 5-8 As shown, the enclosure 32 further includes two second bars 322, which are respectively connected to the two ends of the two first bars 321. In the arrangement direction of the two first bars 321, the sheet radiator 112 corresponds to a partial area of ​​one second bar 322.

[0098] Specifically, in this embodiment, the two second blocking bars 322 and the two first blocking bars 321 are connected end to end to form an annular wave conductor, so that the inductive current coupled on the frame 31 can be conducted along the annular wave conductor. Figure 7 A specific conduction form of the guided electromagnetic wave is shown in FIG. 1 , where the transmission direction of the guided electromagnetic wave on the two first baffles 321 is opposite to the transmission direction of the strip radiator 111. Thus, the working frequency band of the radiating part 1 is further broadened, and the transceiver performance of the radiating part 1 is improved.

[0099] In some embodiments, Figure 5 and Figure 7 As shown, the frame 31 also includes a support bar 33, which is located on the inner side of the enclosure 32. Both ends of the support bar 33 are connected to two first blocking bars 321. The insulating fixing member 23 is a sheet-like structure, and the sheet-like structure is provided with a plurality of fixing holes 211 penetrating the sheet-like structure. The number of lens modules 22 is multiple and they are fixed to the multiple fixing holes 211 one by one. The edge of the insulating fixing member 23 is connected to the enclosure 32, and the length direction of the support bar 33 is perpendicular to the arrangement direction of the fixing holes 211 and is staggered with the fixing holes 211.

[0100] In this embodiment, when the insulating fixing member 23 is connected to the frame 31, the support bar 33 can play a role in supporting the insulating fixing member 23. In particular, when the number of lens modules 22 is large, the support bar 33 can prevent the insulating fixing member 23 from being recessed toward the inner side of the frame 31. On the other hand, the support bar 33 can also play a role in electrically connecting the two first blocking bars 321 (such as Figure 7The support bar 33 can keep the electric potential on the two first baffles 321 consistent, especially when the length of the first baffle 321 is large, to ensure that the conduction direction of the guided electromagnetic waves on the two first baffles 321 is consistent, thereby avoiding the occurrence of a potential difference in the extension direction of the annular waveguide body.

[0101] In some embodiments, Figure 5-6 As shown, the shell 4 includes a back plate 41. The frame 31 is protruded on the outer surface of the back plate 41, and the height of the support bar 33 is less than the height of the enclosure 32. The insulating fixture 23 is installed on the metal fixture 3, one side of the insulating fixture 23 is in contact with the support bar 33, and the other side of the insulating fixture 23 is flush with the top surface of the enclosure 32. In this embodiment, when the insulating fixture 23 is in contact with the support bar 33, the insulating fixture 23 can just be immersed in the enclosure 32, so that the appearance of the camera assembly 2 is smoother.

[0102] Fig. 9 Schematic diagram of the positional relationship between the first shielding plate 61, the frame 31 and the radiation pattern 11 of this embodiment. The outlines of the frame 31 and the radiation portion 1 in the figure are shown with dotted lines, and the outer contours of the first avoidance gap 611 and the second avoidance gap 612 are shown with dotted lines.

[0103] In some embodiments, Figure 1 and Fig. 9 As shown, the electronic device further includes a substrate 51. The substrate 51 is disposed adjacent to the back plate 41, and the radiation pattern 11 is formed on the side of the substrate 51 facing the back plate 41. Thus, through the relative position relationship between the substrate 51 and the back plate 41, the radiation pattern 11 can radiate electromagnetic signals toward the back plate 41, thereby reducing the influence of the electromagnetic signals on the internal components of the electronic device.

[0104] Preferably, the substrate 51 in this embodiment is a plastic plate, and the radiation pattern 11 is formed on the surface of the plastic plate by a surface treatment process such as laser engraving.

[0105] In some embodiments, Figure 3-6As shown, the lens module 22 includes a filter 221 and a lens barrel 222. The radiation part 1 also includes a conductive member 12. The electronic device also includes a circuit board 52, and the circuit board 52 is provided with a first port 521. The lens module 22 is arranged on the circuit board 52 through the lens barrel 222, and the radiation part 1 is electrically connected to the first port 521 through the conductive member 12. The lens module 22 and the radiation pattern 11 are close to the top of the electronic device. In the arrangement direction of the two first baffles 321, the lens module 22 and the radiation pattern 11 are arranged adjacent to the same side of the back plate 41, and the strip radiator 111 corresponds to a first baffle 321 away from the edge of the back plate 41. In this embodiment, the circuit board 52 feeds the radiation part 1 through the first port 521. At the same time, a photosensitive device corresponding to the lens module 22 is provided on the circuit board 52 to collect light passing through the camera assembly 2.

[0106] Preferably, the lens module 22 further comprises a lens disposed in the lens barrel 222. The substrate 51 is further provided with a plurality of windows so that the lens barrel 222 and the conductive member 12 can pass through the substrate 51.

[0107] In some embodiments, Figure 1 and Fig. 9 As shown, the electronic device further includes a first shielding plate 61, which is disposed between the substrate 51 and the circuit board 52. The first shielding plate 61 has a first avoidance notch 611 and a second avoidance notch 612, which penetrate the first shielding plate 61 and are recessed from the same vertex position of the first shielding plate 61 toward the center of the first shielding plate 61.

[0108] In the thickness direction of the first shielding plate 61, the radiation pattern 11 is staggered with the first shielding plate 61 and at least partially corresponds to the first avoidance gap 611 and the second avoidance gap 612. At least part of the frame 31 corresponds to the second avoidance gap 612, and the first stop bar 321 corresponding to the strip radiator 111 corresponds to the second avoidance gap 612.

[0109] The first shielding plate 61 in this embodiment is used to shield the electromagnetic signal of the radiation part 1 to prevent the radiation part 1 from interfering with the components inside the electronic device. At the same time, in order to prevent the first shielding plate 61 from affecting the electromagnetic signal radiated by the radiation part 1, a first avoidance gap 611 and a second avoidance gap 612 are opened on the first shielding plate 61. In this form, the strip radiator 111 of the radiation part 1 is located in the second avoidance gap 612, and most of the sheet radiator 112 of the radiation pattern 11 is located in the first avoidance gap 611. As a result, the setting form of the first shielding plate 61 is simplified.

[0110] In some embodiments, Figure 1-2 and Fig. 9As shown, the electronic device further includes a receiving frame 7. The receiving frame 7 includes a bearing plate 71 and a baffle 72 surrounding the bearing plate 71, the circuit board 52 is disposed on one side of the bearing plate 71, and the shell 4 is disposed on the baffle 72. The receiving frame 7 in this embodiment is used to carry components inside the electronic device and protect the components from collision.

[0111] In some embodiments, Figure 1-2 and Fig. 9 As shown, the electronic device further includes a second shielding plate 62 and a display screen 8. The display screen 8 is disposed on a side of the carrier plate 71 away from the circuit board 52. The second shielding plate 62 is disposed between the carrier plate 71 and the circuit board 52, and at least a portion of the second shielding plate 62 corresponds to the display screen 8 and the frame 31 at the same time. The second shielding plate 62 in this embodiment is used to prevent the electromagnetic signal of the radiation part 1 from being directly radiated to the display screen 8, thereby affecting the image displayed by the electronic device.
