In addition, because the number of the antennas on the middle frame is large, in order to meet the requirement of the clearance area of each antenna, proper distances between the antennas and electronic devices inside the electronic equipment are generally required to be kept, so that the size of the middle frame is easy to be increased, and the thinning design of the electronic equipment is not facilitated. In addition, because a plurality of fractures are required to be arranged on the middle frame, the processing cost of the middle frame can be increased, and the structural strength of the middle frame is lower.

An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 7. Referring to fig. 1, a schematic structural view of an electronic device according to an embodiment of the present application is shown, referring to fig. 2, a cross-sectional view along a line A-A in fig. 1 is shown, referring to fig. 3, a schematic structural view of another angle of the structure shown in fig. 2 is shown, referring to fig. 4, a cross-sectional view of a certain angle of the structure shown in fig. 2 is shown, and referring to fig. 5, a schematic structural view of another angle of the structure shown in fig. 4 is shown.
In an embodiment of the present application, the electronic device may specifically include: a plastic middle frame 10, a plurality of radio frequency antennas 11 and a plurality of millimeter wave antennas 12; the plastic middle frame 10 may include a middle frame base 101 and a frame 102, where the frame 102 is fixedly connected to the outer side of the middle frame base 101; the plurality of radio frequency antennas 11 and the plurality of millimeter wave antennas 12 are all arranged around the plastic middle frame 10; the radio frequency antenna 11 may include a first radiator 111, a first power supply 112 and a ground 113 electrically connected to the first radiator 111, the first radiator 111 being disposed on the frame 101; the millimeter wave antenna 12 may include a plurality of second radiators 121 distributed in an array and a second power feeder 122 electrically connected to the second radiators 121, where the second radiators 121 are disposed on the frame 102.
In practical application, the plastic middle frame 10 may be obtained by injection molding, and the middle frame body 101 and the frame 102 of the plastic middle frame 10 may be in an integral structure to improve production efficiency. Specifically, the middle frame body 101 and the frame 102 may be integrally formed by an injection molding process, so as to achieve a fixed connection therebetween. Then, a plurality of rf antennas 11 and a plurality of millimeter wave antennas 12 are formed on the plastic center 10. Because the injection molding process of the radio frequency antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10 is avoided, the radio frequency antenna 11 and the millimeter wave antenna 12 do not need to bear injection molding pressure, the thickness of the radio frequency antenna 11 and the millimeter wave antenna 12 can be thinner, and the radio frequency antenna 11 and the millimeter wave antenna 12 are not easy to break.
Specifically, the first radiator 111 of the radio frequency antenna 11 and the second radiator 121 of the millimeter wave antenna 12 may be provided in a sheet-like structure, and the thickness of the first radiator 111 and the second radiator 121 may be about 0.02 mm. In addition, the first radiator 111 and the second radiator 121 are arranged on the frame 101 outside the middle frame base body 101, and the distances between the first radiator 111 and the second radiator 121 and electronic devices inside the electronic equipment are far, so that the radio frequency antenna 11 and the millimeter wave antenna 12 can realize a larger clearance area in a smaller space, the radiation performance is better, and the design of lightening and thinning of the electronic equipment is facilitated.
Moreover, the adjacent two radio frequency antennas 11, the adjacent two millimeter wave antennas 12 and the radio frequency antennas 11 and the millimeter wave antennas 12 can be separated by keeping a certain distance, so that the arrangement of a fracture on the plastic middle frame 10 to separate the adjacent antennas can be avoided, the processing cost of the plastic middle frame 10 is reduced, and the structural strength of the plastic middle frame 10 is improved.
In the embodiment of the present application, the outer side of the middle frame body 101 may specifically be the outer side with reference to the internal space of the electronic device. Specifically, in the case that the plastic middle frame 10 is wrapped around the electronic device, a side close to the inside of the electronic device is an inner side of the middle frame body 101, and a side close to the outside of the electronic device is an outer side of the middle frame body 101. Because the frame 102 is disposed on the outer side of the middle frame base 101, and the first radiator 111 and the second radiator 121 are disposed on the frame 101, the distances between the first radiator 111 and the second radiator 121 and the electronic devices inside the electronic device are far, and the radio frequency antenna 11 and the millimeter wave antenna 12 can achieve a larger headroom area in a smaller space, so as to achieve better antenna performance.
In practical applications, the rf antenna 11 may be used to radiate and receive rf antenna signals, and the rf antenna 11 typically operates in a frequency band below 6 GHz. Millimeter-wave antenna 12 may be used to effect the radiation and reception of millimeter-wave antenna signals and millimeter-wave antenna 12 typically operates in the millimeter-wave frequency band. In the embodiment of the application, the radio frequency antenna 11 and the millimeter wave antenna 12 are simultaneously arranged in the electronic equipment, so that the broadband radiation of antenna signals can be realized, and the communication quality of the electronic equipment is improved.
In particular, the first radiator 111 may be used to radiate or receive radio frequency signals. The first power feeder 112 may be used to feed the first radiator 111 with an electrical signal of a radio frequency module inside the electronic device, and feed the radio frequency signal received by the first radiator 111 into the radio frequency module inside the electronic device. The grounding body 113 may be an electrical connection structure of a contact, a pin, an electrical connection pad, etc., and the grounding body 113 may be used to achieve connection between the first radiator 111 and the reference ground.
Similarly, the second radiator 121 may be used to radiate or receive millimeter wave signals. The second power feeder 122 may be used to feed the millimeter wave signal inside the electronic device into the second radiator 121 and to feed the millimeter wave signal received by the second radiator 121 into the electronic device.
Note that in fig. 2, only a case where the millimeter wave antenna 12 includes 4 second radiators 121 is shown, but in practical applications, the number of second radiators 121 in the millimeter wave antenna 12 may also be other values, for example, 6, 8, 12, or the like, and the number of second radiators 121 in the millimeter wave antenna 12 is not particularly limited in the present application.
In an alternative embodiment of the present application, the array direction of the plurality of second radiators 121 may be consistent with the length direction of the first radiator 111, so as to further reduce the layout space of the plurality of second radiators 121, which is beneficial to the light and thin design of the plastic middle frame 10.
In some alternative embodiments of the present application, the plastic middle frame 10 may be made by LDS (Laser Direct Structuring, laser direct structuring technology), and the rf antenna 11 and the millimeter wave antenna 12 may be LDS antennas.
Specifically, the plastic middle frame 11 may be made of LDS plastic. The LDS plastic is a production technology of professional laser processing, ejection and electroplating processes, and by adding certain raw materials containing special components into the plastic, common plastic elements can be endowed with an electrical interconnection function, and a laser technology can be utilized to directly print a circuit board on the LDS plastic in a three-dimensional way, so that the traditional circuit board is not needed any more, the circuit design is more flexible, and the most important is that the volume of the product can be obviously reduced.
In the embodiment of the present application, the plurality of radio frequency antennas 11 and the plurality of millimeter wave antennas 12 can be directly manufactured in the plastic middle frame 10 by the LDS technology, and the plurality of radio frequency antennas 11 and the plurality of millimeter wave antennas 12 are all configured as LDS antennas. Thus, not only the thicknesses of the radio frequency antenna 11 and the millimeter wave antenna 12 can be designed to be thin, but also the headroom area of the radio frequency antenna 11 and the millimeter wave antenna 12 can be increased. In addition, the radio frequency antenna 11 and the millimeter wave antenna 12 can be flexibly arranged at any position of the plastic middle frame 10, which is beneficial to flexible arrangement of the radio frequency antenna 11 and the millimeter wave antenna 12. In addition, the plastic middle frame 10 can be prevented from being provided with a fracture to separate the two adjacent radio frequency antennas 11, the two adjacent millimeter wave antennas 12 and the radio frequency antennas 11 and the millimeter wave antennas 12, so that the processing cost of the plastic middle frame 10 is reduced, and the structural strength of the plastic middle frame 10 is improved.
In other alternative embodiments of the present application, the surface of the plastic middle frame 10 is provided with a groove, and the radio frequency antenna 11 and the millimeter wave antenna 12 are embedded in the groove.
Specifically, a groove may be formed in a region of the plastic middle frame 10 where the antenna needs to be disposed by a processing method such as molding or removing processing, and then the sheet-shaped radio frequency antenna 11 and the millimeter wave antenna 12 may be embedded into the groove. In practical applications, in order to increase the connection strength between the rf antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10, the rf antenna 11, the millimeter wave antenna 12 and the plastic middle frame 10 may be in interference fit, or an adhesive layer may be disposed between the rf antenna 11, the millimeter wave antenna 12 and the grooves. The embodiment of the present application is not limited thereto.
It should be noted that, when the radio frequency antenna 11 and the millimeter wave antenna 12 are embedded in the groove of the plastic middle frame 10 in an embedded manner, in order to increase the clearance area of the radio frequency antenna 11 and the millimeter wave antenna 12, the radio frequency antenna 11 and the millimeter wave antenna 12 may be sheet-shaped antennas, and in order to reduce the processing cost of the electronic device, the material of the plastic middle frame 10 may be at least one of polycarbonate plastic, glass fiber polycarbonate plastic, and glass fiber polyamide plastic.
In the embodiment of the present application, the surface of the frame 102, which is close to the middle frame substrate 101, is a first surface 1021, and the first radiator 111 may be disposed on the first surface 1021; the second radiator 121 may be disposed in the frame 102 and parallel to the first radiator 111.
Referring to fig. 6, a schematic structural diagram of a radio frequency antenna and a millimeter wave antenna according to the present application is shown, and referring to fig. 7, a partially enlarged view of the structure shown in fig. 6 is shown. As shown in fig. 6 and 7, since the first radiator 111 is disposed on the first surface 1021, the first radiator 111 may be grounded through the grounding body 113, and the second radiator 121 is disposed within the bezel 101 and parallel to the first radiator 111, and thus the first radiator 111 may serve as a reflective ground for the second radiator 121. Thus, the operation of additionally grounding the second radiator 121 can be avoided, the structure of the millimeter wave antenna 12 is simplified, and the design of the plastic middle frame 10 is more favorable for light and thin.
In some alternative embodiments of the present application, the frame 102 is provided with slots 1022 distributed in an array, and the second radiator 121 is disposed on a wall of the slots 1022; the frame 102 is further provided with a through hole penetrating the first surface 1021 and the slot 1022, and the second power feeder 122 may pass through the through hole and be connected to the second radiator 121.
In practical applications, the slot 1022 may be formed in the plastic middle frame 10 in a processing manner such as mold forming or removing, where the second radiator 121 needs to be disposed, such that at least two walls of the slot 1022 are parallel to the first surface 1021, and a through hole is disposed between the slot 1022 and the first surface 1021. Then, a second radiator 121 is formed on the wall of the slot 1022 using the LDS process. Finally, the second power supply 122 is inserted into the through hole and connected with the second radiator 121
Specifically, since the second power feeder 122 is embedded in the through hole penetrating the slot 1022 and the first surface 1021, one end of the second power feeder 122 is close to the inside of the electronic device, and the other end is electrically connected to the second radiator 121, so that it is possible to facilitate feeding of the millimeter wave signal inside the electronic device into the second radiator 121, and feeding of the millimeter wave signal received by the second radiator 121 into the inside of the electronic device.
Alternatively, the second power feeder 122 may be a conductive metal pillar, which is insulated from the first radiator 111, so as to realize separation between the first radiator 111 and the second radiator 121, so that the radio frequency antenna 11 and the millimeter wave antenna 12 may operate independently, and mutual interference between the radio frequency antenna 11 and the millimeter wave antenna 12 is avoided.
In practical applications, the connection between the conductive metal pillar and the first radiator 111 may be cut off, so as to realize insulation between the conductive metal pillar and the first radiator 111. For example, an insulating layer may be disposed on a surface of the conductive metal pillar, which is in contact with the first radiator 111, or an insulating foam, an insulating rubber pad, or the like may be interposed between the conductive metal pillar and the first radiator 111 to insulate the conductive metal pillar from the first radiator 111. The embodiment of the present application is not limited thereto.
In other alternative embodiments of the present application, the number of the second power feeding bodies 122 is plural, and each second power feeding body 122 is connected to the non-center region of the second radiator 121 to realize multi-polarized radiation of the millimeter antenna.
In practical applications, when the second power feeder 122 is connected to the non-central region of the second radiator 121, polarized radiation in a certain direction can be realized, and the polarization direction is also different when the second power feeder is connected to a different position of the non-central region of the second radiator 121.
In the embodiment of the present application, by connecting the plurality of second power feeders 122 at different positions in the non-center region of the second radiator 121, polarized radiation in a plurality of directions can be realized, and the radiation performance of the millimeter wave antenna 12 can be improved.
As shown in fig. 7, in the case where the shape of the second radiator 121 is rectangular, the number of the second power feeding bodies 122 may be 2, in which one second power feeding body 122 is connected at a position near the long side edge of the second radiator 121 and the other second power feeding body 122 is connected at a position near the short side edge of the second radiator 121 to realize polarization in two different directions to realize dual polarized radiation of the millimeter wave antenna 12.
It should be noted that fig. 2 to fig. 7 only show the case where the shape of the second radiator 121 is rectangular, and the number of the second power feeders 122 is 2, but in practical applications, the shape of the second radiator 121 may also be a circle, a triangle, or other abnormal shapes, and the number of the second power feeders 122 may also be 3, 4, or 6, etc., and the shape of the second radiator 121 and the number of the second power feeders 122 are not specifically limited in the embodiment of the present application.
In other alternative embodiments of the application, slot 1022 may include opposing first slot wall 1023 and second slot wall 1024, both first slot wall 1023 and second slot wall 1024 being parallel to first surface 1021, first slot wall 1023 being proximate first surface 1021; the second radiator 121 is disposed on the second slot wall 1024, so that the second radiator 121 may be disposed as far away from the first surface 1021 as possible, thereby increasing the distance between the second radiator 121 and the electronic device inside the electronic device, increasing the headroom area of the millimeter wave antenna 12, and further improving the radiation performance of the millimeter wave antenna 12.
In still other alternative embodiments of the present application, millimeter-wave antenna 12 may further comprise a plurality of third radiators 123, one third radiator 123 corresponding to each second radiator 121; the third radiator 123 is disposed on the first slot wall 1023 and coupled to the second radiator 121.
In practical applications, the third radiator 123 and the second radiator 121 may be disposed at a distance from each other to maintain a reasonable coupling gap. In this way, in the case where the second radiator 121 radiates the millimeter wave signal, the millimeter wave signal may be coupled to the third radiator 123, so as to expand the bandwidth of the second radiator 121 and assist the second radiator 121 in radiating the millimeter wave signal, thereby expanding the bandwidth of the millimeter wave antenna 12 and improving the radiation performance of the millimeter wave antenna 12.
Alternatively, the third radiator 123 may have a size larger than that of the second radiator 121, so that the millimeter wave signal radiated from the second radiator 121 may be well coupled to the third radiator 123. In practical applications, the third radiator 123 and the second radiator 122 may operate in different frequency bands, and the frequency band in which the third radiator 123 operates may be a left-right or positive-negative change of the frequency band in which the second radiator 121 operates. By operating the third radiator 123 and the second radiator 122 in different frequency bands, the bandwidth of the millimeter wave antenna 12 can be expanded.
In the process of sequentially penetrating the second power supply 122 through the first surface 1021, the first groove wall 1023, and the second groove wall 1024, the second power supply 122 is electrically connected to only the second radiator 121, and is not connected to the first power supply 111 on the first surface 1021 and the third radiator 123 on the first groove wall 1023.
In practical applications, the working frequency band of the millimeter wave antenna 12 may be designed by designing the external dimensions of the second radiator 121 and the third radiator 123, and the coupling distance between the second radiator 121 and the third radiator 123. On the basis of this, by setting the number of the second power feeders 122 and the positions at which the second power feeders 122 are connected to the second radiator 121, the polarization direction of the millimeter wave antenna 12 can be designed.
In an embodiment of the present application, the electronic device may further include: the metal frame 13, the metal frame 13 wraps up in the inboard of middle frame base member 101, and with the inboard fixed connection of middle frame base member 101, the material of metal frame 13 includes: at least one of magnesium alloy, aluminum alloy, zinc alloy and titanium alloy.
