[0025] like Figures 1 to 11 As shown, the electronic device includes: a frame 10.

[0026] A communication antenna 20 is provided in the frame 10, and the communication antenna 20 is used to enable the electronic device to communicate. A flexible coupling antenna 30 is provided on the frame 10. The frame 10 has a side 101 facing the back cover of the electronic device, and the flexible coupling antenna 30 is provided on the side 101 of the frame 10 facing the back cover of the electronic device; the communication antenna 20 has a slit 21, and the flexible coupling antenna 30 covers at least part of the slit 21, and the flexible coupling antenna 30 is coupled with the communication antenna 20.

[0027] In the embodiment of the present application, since the communication antenna 20 is provided in the frame 10, the electronic device can communicate through the communication antenna 20. Since the flexible coupling antenna 30 is provided on the side 101 of the frame 10 facing the back cover of the electronic device, and the flexible coupling antenna 30 covers at least the slit 21 of the communication antenna 20, the flexible coupling antenna 30 is coupled with the communication antenna 20, and the flexible coupling antenna 30 can take into account the communication antennas 20 on both sides of the slit 21, so that the coupling effect between the flexible coupling antenna 30 and the communication antenna 20 is better, so that the communication antenna 20 is coupled with the flexible coupling antenna 30, and the antenna performance of the communication antenna 20 can be improved, so that the communication performance of the electronic device is improved. That is, in the embodiment of the present application, by providing the flexible coupling antenna 30 on the frame 10, and the flexible coupling antenna 30 covers at least part of the slit 21 of the communication antenna 20, so that the flexible coupling antenna 30 is coupled with the communication antenna 20 inside the frame 10, the flexible coupling antenna 30 can improve the antenna performance of the communication antenna 20, and thus the communication performance of the electronic device is improved.

[0028] It should be noted that the projection of the break 21 on the side 101 facing the back cover of the electronic device can be located in the middle of the projection of the flexible coupling antenna 30 on the side 101 facing the back cover of the electronic device, which is equivalent to half of the flexible coupling antenna 30 being coupled to the communication antenna 20 on one side of the break 21, and the other half of the flexible circuit board antenna being coupled to the communication antenna 20 on the other side of the break 21, which can be beneficial to improve the antenna performance of the communication antenna 20. In addition, in the embodiment of the present application, the flexible coupling antenna 30 can cover part of the break 21, and of course the flexible coupling antenna 30 can also cover the entire break 21. This is not limited in the embodiment of the present application. Among them, the more the flexible coupling antenna 30 covers the break 21, the better the coupling effect of the flexible coupling antenna 30 and the communication antenna 30.

[0029] In addition, in the related art, the electronic device includes a frame 10, the frame 10 has a first side wall and a second side wall opposite to each other, a first antenna is arranged in the first side wall, a second antenna is arranged in the second side wall, and a key assembly is arranged on the first side wall, so that the antenna clearance of the first antenna is smaller than the antenna clearance of the second antenna, so that the antenna performance of the first antenna is weaker than the antenna performance of the second antenna, so that the communication performance of the electronic device is seriously affected during the user's actual use of the electronic device. In the embodiment of the present application, by arranging a flexible coupling antenna 30 on the frame 10, the flexible coupling antenna 30 is coupled with the communication antenna 20 in the frame 10, so that the communication antenna 20 is coupled by the flexible coupling antenna 30, so that the antenna performance of the communication antenna 20 is improved, and then the communication performance of the electronic device is improved.

[0030] It should be noted that, in the embodiment of the present application, the frame 10 may include a first side wall and a second side wall opposite to each other, and a communication antenna 20 may be provided in both the first side wall and the second side wall, and a flexible coupling antenna 30 may be provided on both the first side wall and the second side wall, and the flexible coupling antenna 30 on the first side wall is coupled with the communication antenna 20 in the first side wall, and the flexible coupling antenna 30 on the second side wall is coupled with the communication antenna 20 in the second side wall. Of course, the flexible coupling antenna 30 may also be provided only on the first side wall, so that the flexible coupling antenna 30 on the first side wall is coupled with the communication antenna 20 in the first side wall. Among them, the antenna performance of the communication antenna 20 in the first side wall is weaker than the antenna performance of the communication antenna 20 in the second side wall.

[0031] In addition, in the embodiment of the present application, the electronic device may further include a back cover 100 and a display screen 200, a side 101 of the frame 10 facing the back cover of the electronic device is connected to the back cover 100, the frame 10 also has a mounting surface opposite to the side 101 facing the back cover of the electronic device, and the display screen 200 is bonded to the mounting surface by an adhesive.

[0032] In addition, the flexible coupling antenna 30 can occupy a partial position on the side 101 of the frame 10 facing the back cover of the electronic device, so that when the side 101 of the frame 10 facing the back cover of the electronic device is connected to the back cover 100, the flexible coupling antenna 30 can be shielded by the back cover 100 to prevent the flexible coupling antenna 30 from being exposed, which would cause the flexible coupling antenna 30 to be easily damaged.

[0033] In addition, in some embodiments, the flexible coupling antenna 30 may be a flexible circuit board antenna, and a mounting groove 102 is provided on a side 101 of the frame body 10 facing the back cover of the electronic device, and the flexible circuit board antenna is disposed in the mounting groove 102 .

[0034] Since the mounting groove 102 is provided on the side 101 of the frame 10 facing the back cover of the electronic device, when the flexible coupling antenna 30 is provided on the frame 10, the flexible circuit board antenna can be directly provided in the mounting groove 102, so that the flexible circuit board antenna is coupled with the communication antenna 20 in the frame 10, thereby improving the antenna performance of the communication antenna 20 in the frame 10. In addition, by providing the flexible circuit board antenna in the mounting groove 102, it is possible to avoid the problem that the flexible circuit board antenna protrudes from the side 101 of the frame 10 facing the back cover of the electronic device, resulting in the side 101 of the frame 10 facing the back cover of the electronic device being difficult to connect to the back cover 100.

[0035] It should be noted that the mounting groove 102 can be located at a position on the side 101 of the back cover of the frame 10 facing the electronic device where the back cover 100 is not connected, and after the back cover 100 is connected to the side 101 of the back cover of the frame 10 facing the electronic device, the back cover 100 can cover the notch of the mounting groove 102, so that the back cover 100 can cover the flexible circuit board antenna to avoid the problem of the flexible circuit board antenna being exposed and easily damaged.

[0036] In addition, in the related art, the electronic device includes a frame 10, the frame 10 has a first side wall and a second side wall opposite to each other, a first antenna is arranged in the first side wall, a second antenna is arranged in the second side wall, and a key assembly is arranged on the first side wall, so that the antenna clearance of the first antenna is smaller than the antenna clearance of the second antenna, so that the antenna performance of the first antenna is weaker than the antenna performance of the second antenna. In order to improve the antenna performance of the first antenna, a groove is provided on the first side wall, and a printed circuit board is inserted into the groove, and the antenna performance of the first antenna is improved by the printed circuit board, but the cost of the printed circuit board is high, which is not conducive to the wide promotion of electronic equipment to the market. In the embodiment of the present application, by providing a mounting groove 102 on a side 101 of the frame 10 facing the back cover of the electronic device, the flexible circuit board antenna is arranged in the mounting groove 102, and the flexible circuit board antenna is coupled with the communication antenna 20, so as to improve the antenna performance of the communication antenna 20, and the cost of the flexible circuit board antenna is low, so that the cost of the electronic device can be reduced, which is conducive to improving the promotion of the electronic device to the market, that is, improving the market promotion of the electronic device.

[0037] In addition, in some embodiments, the frame 10 may include a plastic part 11, in which a communication antenna 20 is disposed, and the plastic part 11 has a side 101 facing the back cover of the electronic device, the communication antenna 20 is exposed in the mounting groove 102, the flexible circuit board antenna is disposed at the bottom of the mounting groove 102, and at least part of the flexible circuit board antenna is attached to the communication antenna 20.

[0038] Since the communication antenna 20 is arranged in the plastic part 11, and the plastic part 11 has a side 101 facing the back cover of the electronic device, the installation groove 102 is equivalent to being opened on the plastic part 11, so that the installation groove 102 can be easily opened on the side 101 of the plastic part 11 facing the back cover of the electronic device. Since the communication antenna 20 is exposed in the installation groove 102, when the flexible circuit board antenna is arranged in the installation groove 102, the flexible circuit board antenna can be arranged at the bottom of the installation groove 102, and at least part of the flexible circuit board antenna is attached to the communication antenna 20, so that the flexible circuit board antenna and the communication antenna 20 are effectively coupled, which is beneficial to the flexible circuit board antenna to improve the antenna performance of the communication antenna 20. That is, by arranging the communication antenna 20 to be exposed in the installation groove 102, and at least part of the flexible circuit board antenna is attached to the communication antenna 20, it is beneficial for the flexible circuit board antenna to improve the antenna performance of the communication antenna 20.

[0039] It should be noted that the frame 10 may further include a metal portion 12 , which is connected to the plastic portion 11 . The metal portion 12 may improve the strength of the frame 10 .

[0040] In addition, in the embodiment of the present application, when the mounting groove 102 is opened on the plastic part 11 of the frame 10, the plastic part 11 of the frame 10 can be cut by a cutting process so that the mounting groove 102 is formed on the plastic part 11, and in the process of cutting the plastic part 11, the cutting can be stopped when the communication antenna 20 is cut, and the communication antenna 20 is exposed in the mounting groove 102, ensuring that when the flexible circuit board antenna is subsequently set in the mounting groove 102, the flexible circuit board antenna can be attached to the communication antenna 20.

[0041] In addition, the bottom of the mounting groove 102 can be parallel to the side 101 of the frame 10 facing the back cover of the electronic device, that is, the plane where the bottom of the mounting groove 102 is located is a horizontal plane. At this time, the surface of the communication antenna 20 exposed in the mounting groove 102 can also be a horizontal plane, so the flexible circuit board can be directly attached to the communication antenna 20 and the bottom of the mounting groove 102 to improve the antenna performance of the communication antenna 20.

[0042] In addition, in some embodiments, the bottom of the mounting groove 102 is inclined relative to the side 101 of the frame 10 toward the back cover of the electronic device, and an inclined surface 201 is provided on the communication antenna 20, and the flexible circuit board antenna is attached to the bottom of the mounting groove 102 and the inclined surface 201 of the communication antenna 20.

[0043] Since the bottom of the mounting groove 102 is inclined relative to the side 101 of the frame 10 facing the back cover of the electronic device, and the communication antenna 20 is provided with an inclined surface 201, when the flexible circuit board antenna is arranged in the mounting groove 102, the flexible circuit board antenna can be attached to the bottom of the mounting groove 102 and the inclined surface 201 of the communication antenna 20. The bottom of the mounting groove 102 is inclined, and the inclined surface 201 of the communication antenna 20 is inclined, so that the coupling area between the flexible circuit board antenna and the communication antenna 20 is increased, and the antenna performance of the communication antenna 20 after being coupled by the flexible coupling antenna 30 can be further improved. That is, by setting the bottom of the mounting groove 102 to be inclined and providing the inclined surface 201 on the communication antenna 20, the flexible circuit board antenna can be attached to the inclined surface 201, and the coupling area between the flexible circuit board antenna and the communication antenna 20 is increased, thereby improving the antenna performance of the communication antenna 20.

[0044] It should be noted that when the mounting groove 102 is opened on the plastic part 11 of the frame 10, the cutting process can be used to cut the plastic part 11 of the frame 10 so that the mounting groove 102 is formed on the plastic part 11, and after the communication antenna 20 is exposed in the mounting groove 102, the cutting can be continued so that the bottom of the mounting groove 102 is inclined relative to the side 101 of the frame 10 facing the back cover of the electronic device after being cut, and the communication antenna 20 is cut so that an inclined surface 201 is formed on the communication antenna 20, and the flexible circuit board antenna can be subsequently attached to the inclined bottom of the mounting groove 102 and the inclined surface 201 of the communication antenna 20.

[0045] In addition, in some embodiments, the length of the flexible circuit board antenna is greater than or equal to 19 mm. By such a setting, the flexible circuit board can have a sufficient size, thereby increasing the coupling area of ​​the flexible circuit board and the communication antenna 20, so that the antenna performance of the communication antenna 20 is further improved. That is, by setting the length of the flexible circuit board antenna to be greater than or equal to 19 mm, the antenna performance of the communication antenna 20 can be further improved.

[0046] It should be noted that the length of the flexible circuit board antenna can be any value greater than or equal to 19 mm, for example, the length of the flexible circuit board antenna is 19 mm, for example, the length of the flexible circuit board antenna is 20 mm, for example, the length of the flexible circuit board antenna is 23 mm. This is not limited in the embodiments of the present application.

[0047] In addition, in some embodiments, the flexible circuit board antenna has a back side, the back side faces the bottom of the mounting groove 102, and a first adhesive layer 301 is provided on the back side. The flexible circuit board antenna is bonded to the bottom of the mounting groove 102 and the communication antenna 20 through the first adhesive layer 301; wherein the thickness of the first adhesive layer 301 is less than or equal to 30 microns.

[0048] Since the first adhesive layer 301 is provided on the back side, when the flexible circuit board antenna is provided in the mounting groove 102, the flexible circuit board antenna can be directly bonded to the groove bottom of the mounting groove 102 and the communication antenna 20 through the first adhesive layer 301, so that it is convenient to provide the flexible circuit board antenna in the mounting groove 102. In addition, the thickness of the first adhesive layer 301 is less than or equal to 30 microns, so that the thickness of the first adhesive layer 301 is small, which can effectively avoid the problem that the first adhesive layer 301 is too thick, causing the flexible circuit board antenna to be easily warped.

[0049] It should be noted that the first adhesive layer 301 may be a double-sided adhesive layer. Of course, the first adhesive layer 301 may also be an adhesive layer formed by other materials with adhesive properties, for example, the first adhesive layer 301 is formed by glue. The specific type of the first adhesive layer 301 is not limited in the present embodiment.

[0050] In addition, the thickness of the first adhesive layer 301 can be any value less than or equal to 30 microns, for example, the thickness of the first adhesive layer 301 is 30 microns, for another example, the thickness of the first adhesive layer 301 is 28 microns, for another example, the thickness of the first adhesive layer 301 is 25 microns. This embodiment of the present application is not limited here.

[0051] In addition, in some embodiments, the flexible circuit board antenna also has a front side opposite to the back side, and a protective film 302 and a second adhesive layer 303 are provided on the front side, and the protective film 302 is bonded to the front side through the second adhesive layer 303; wherein, the thickness of the protective film 302 is less than or equal to 25 microns, and the thickness of the second adhesive layer 303 is less than or equal to 25 microns.

[0052] Since the protective film 302 is bonded to the front surface through the second adhesive layer 303, the protective film 302 can protect the flexible circuit board antenna. In addition, the thickness of the protective film 302 is less than or equal to 25 microns, and the thickness of the second adhesive layer 303 is less than or equal to 25 microns, which can make the thickness of the flexible circuit board antenna smaller, thereby avoiding the problem of the flexible circuit board antenna being easily warped. The material of the protective film 302 can be polyimide resin.

[0053] It should be noted that the thickness of the second adhesive layer 303 can be any value less than or equal to 25 microns, for example, the thickness of the second adhesive layer 303 is 25 microns, for example, the thickness of the second adhesive layer 303 is 20 microns, for example, the thickness of the protective film 302 is 23 microns. In this regard, the embodiment of the present application is not limited here. In addition, the thickness of the protective film 302 can be any value less than or equal to 25 microns, for example, the thickness of the protective film 302 is 25 microns, for example, the thickness of the protective film 302 is 20 microns, for example, the thickness of the protective film 302 is 23 microns.

[0054] In addition, in some embodiments, a conductive layer 103 is provided on a side 101 of a part of the frame 10 facing the back cover of the electronic device, the conductive layer 103 covers at least a part of the break 21, and the conductive layer 103 forms a flexible coupling antenna 30. Through such a setting, it is possible to avoid the problem of grooves on the frame 10, which affects the strength of the frame 10, and the conductive layer 103 can be directly provided on the side 101 of the frame 10 facing the back cover of the electronic device, so that the method of providing the flexible coupling antenna 30 on the side 101 of the frame 10 facing the back cover of the electronic device is simple, and the flexible coupling antenna 30 formed by the conductive layer 103 can improve the antenna performance of the communication antenna 20, which is conducive to improving the antenna performance of the electronic device.

[0055] In addition, in the embodiment of the present application, the conductive layer 103 can be formed by coating a conductive silver paste on the side 101 of the frame 10 facing the back cover of the electronic device. Among them, the conductive silver paste has a low cost and good performance, which is conducive to improving the performance of the flexible coupling antenna 30. Of course, the conductive layer 103 can also be formed by other conductive materials, for example, the conductive layer 103 is formed by coating a conductive copper paste. In this regard, the embodiment of the present application is not limited here.

[0056] In addition, in the embodiment of the present application, the thickness of the conductive layer 103 can be less than or equal to 0.13 mm. Through such a setting, the thickness of the conductive layer 103 can be made smaller, thereby avoiding the problem that the thickness of the conductive layer 103 is larger, which may cause the thickness of the electronic device to be larger. That is, by setting the thickness of the conductive layer 103 to be less than or equal to 0.13 mm, it can be beneficial to make the electronic device lighter and thinner while ensuring that the antenna performance of the communication antenna 20 is improved.

[0057] It should be noted that the thickness of the conductive layer 103 can be any setting less than or equal to 0.13 mm, for example, the thickness of the conductive layer 103 is 0.13 mm, and for another example, the thickness of the conductive layer 103 is 0.1 mm. This embodiment of the present application does not limit this.

[0058] In addition, in the embodiment of the present application, when the frame 10 includes the plastic part 11 , the plastic part 11 has a side 101 facing the back cover of the electronic device, and the conductive layer 103 is disposed on the side 101 of the plastic part 11 facing the back cover of the electronic device.

[0060] In the embodiment of the present application, since the communication antenna 20 is provided in the frame 10, the electronic device can communicate through the communication antenna 20. Since the flexible coupling antenna 30 is provided on the side 101 of the frame 10 facing the back cover of the electronic device, and the flexible coupling antenna 30 covers at least the slit 21 of the communication antenna 20, the flexible coupling antenna 30 is coupled with the communication antenna 20, and the flexible coupling antenna 30 can take into account the communication antennas 20 on both sides of the slit 21, so that the coupling effect between the flexible coupling antenna 30 and the communication antenna 20 is better, so that the communication antenna 20 is coupled with the flexible coupling antenna 30, and the antenna performance of the communication antenna 20 can be improved, so that the communication performance of the electronic device is improved.
