Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to an electronic device. Background Technology

[0002] Mobile phones and other electronic devices need to have USB ports to enable functions such as charging and data transfer;

[0003] In related technologies, a through-hole is typically made in the metal frame of an electronic device to house the USB interface. However, with the trend towards thinner and lighter electronic devices, making a through-hole in the metal frame to house the USB interface reduces the structural strength of that portion of the metal frame, making it unsuitable for deploying a slotted antenna. This reduces the area on the metal frame available for antenna deployment. Summary of the Invention

[0004] The purpose of this application embodiment is to provide an electronic device that, after opening a through hole in a metal frame to set up a USB interface, can set up a slotted antenna in that part of the metal frame while ensuring the structural strength of that part of the metal frame.

[0005] This application provides an electronic device, which includes: a metal frame, a metal frame, and a USB interface;

[0006] The metal frame is arranged around the perimeter of the metal frame;

[0007] The first side of the metal frame includes a first through hole, a gap, and a first segment and a second segment located on opposite sides of the gap. The first through hole is located in the first segment and communicates with the gap. The USB interface is embedded in the first through hole.

[0008] The second segment is provided with a first power supply point;

[0009] The metal frame has a first gap with the first part of the first segment, the metal frame is fixedly connected to the second part of the first segment, the first gap communicates with the fracture, the first part and the second part are respectively located on opposite sides of the first through hole, and the first part and the second part extend in the same direction as the first side.

[0010] In this embodiment, the first segment is designed in layers. The first part located on one side of the USB interface has a first gap between it and the metal frame. When the second segment obtains the excitation signal from the first feed point, the second segment acts as the main radiator to excite the resonant mode. The second segment and the first part are coupled based on the gap, so that the first part constitutes a parasitic radiator, thus realizing the antenna deployment at the metal frame location of the USB interface. In addition, the second part located on the other side of the USB interface is fixedly connected to the metal frame. In this way, the structural strength of the metal frame at the USB interface can be strengthened by the second part fixedly connected to the metal frame. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0022] See Figure 1 The electronic device provided in this application embodiment includes: a metal frame 1, a metal frame 2, and a USB interface 3;

[0023] The metal frame 1 is wrapped around the perimeter of the metal frame 2;

[0024] The first side 10 of the metal frame 1 includes a first through hole 11, a gap 12, and a first segment 13 and a second segment 14 located on opposite sides of the gap 12. The first through hole 11 is located in the first segment 13, the first through hole 11 communicates with the gap 12, and the USB interface 3 is embedded in the first through hole 11.

[0025] The second segment 14 is provided with a first power supply point 141;

[0026] There is a first gap 20 between the metal frame 2 and the first part 131 of the first segment 13. The metal frame 2 is fixedly connected to the second part 132 of the first segment 13. The first gap 20 is connected to the fracture 12. The first part 131 and the second part 132 are located on opposite sides of the first through hole 11, and the first part 131 and the second part 132 extend in the same direction as the first side 10.

[0027] In some embodiments, the metal frame 2 and the metal border 1 are typically an integral metal structure. In this case, the first gap 20 can be achieved by slotting the metal frame 2, for example, by slotting the metal frame 2 and the first part 131 to space the long sides of the metal frame 2 and the first part 131 along the extension direction of the first side 10.

[0028] In some embodiments, during the process of feeding the second segment 14 through the first feed point 141, the second segment 14 is excited to act as the main radiator of the antenna and radiate signals. At this time, since the first part 131 is coupled to the second segment 14 through the gap 12, the first part 131 can be excited to act as the parasitic radiator of the antenna and radiate signals.

[0029] It should be noted that the metal frame 2 is a grounded structure. Since there is a first gap 20 between the first part 131 and the metal frame 2, the side of the first part 131 along the extension direction of the first side 10 and the end of the first part 131 facing the gap 12 are suspended, thereby enabling the first part 131 to act as a radiator.

[0030] Furthermore, since the second part 132 is fixedly connected to the metal frame 2, that is, the side of the second part 132 extending along the first side 10 is grounded, the second part 132 will not excite a radiated signal due to coupling with the second segment 14 through the gap 12.

[0031] In other implementations, such as Figure 4 As shown, a second feed point 40 can be set on the first part 131. In this case, the first part 131 can serve as the radiator of another antenna.

[0032] In this embodiment, the first part 131 can be fed through the second feed point 40. At this time, the first part 131 can form an additional antenna, increasing the number of antennas of the electronic device.

[0033] There are also other implementation methods, such as Figure 4 As shown, the electronic device also includes a tuning module 50, which is electrically connected to the first part 131.

[0034] In this way, the resonant frequency of the first part 131 can be adjusted based on the tuning module 50.

[0035] It should be noted that when the resonant frequency of the first part 131 is the same as the resonant frequency of the second segment 14, the first part 131 can enhance the antenna radiation efficiency of the second segment 14.

[0036] When the resonant frequency of the first part 131 is inconsistent with the resonant frequency of the second segment 14, the antenna radiation mode of the electronic device can be increased, such as expanding the antenna operating frequency band of the electronic device.

[0037] It should be noted that, Figure 4In this example, the second feed point 40 is located on the side of the first part 131 facing the gap 12, and the tuning module 50 is electrically connected to the side of the first part 131 away from the gap 12. In other embodiments, the positions of the second feed point 40 and the tuning module 50 can be adjusted according to the operating frequency of the second feed point 40 and the antenna mode of the first part 131. Here, the specific positions of the second feed point 40 and the tuning module 50 electrically connected to the first part 131 are not limited.

[0038] In some implementations, one end of the back-facing gap 12 of the first part 131 can be directly grounded or grounded through the metal frame 2 to ground the excitation signal.

[0039] In some embodiments, the second part 132 is fixedly connected to the metal frame 2. This can be because the second part 132 and the metal frame 2 are an integral metal structure, or the second part 132 is fixedly connected to the metal frame 2 by welding or other methods.

[0040] This can enhance the structural strength of the second part 132 and reduce the risk of the first segment 13 cracking due to frequent USB plugging and unplugging.

[0041] In some embodiments, one end of the back-facing fracture 12 of the first part 131 can be fixedly connected to the metal frame 2. For example, the one end of the back-facing fracture 12 of the first part 131 and the metal frame 2 can be designed as an integral metal structure. In this way, the one end of the back-facing fracture 12 of the first part 131 can be grounded through the metal frame 2 to realize the grounding of the excitation signal on the first part 131.

[0042] In this embodiment, the first segment 13 is designed in layers. The first part 131 located on one side of the USB interface 3 has a first gap 20 between it and the metal frame 2. When the second segment 14 obtains the excitation signal from the first feed point 141, the second segment 14 acts as the main radiator to excite the resonant mode. The second segment 14 is coupled to the first part 131 based on the gap 12, so that the first part 131 constitutes a parasitic radiator. This realizes the antenna deployment at the metal frame 1 where the USB interface 3 is located. In addition, the second part 132 located on the other side of the USB interface 3 is fixedly connected to the metal frame 2. In this way, the structural strength of the metal frame 1 at the USB interface 3 can be strengthened by the second part 132 fixedly connected to the metal frame 2.

[0043] As an optional implementation method, such as Figure 2 , Figure 3 and Figure 5 As shown, the electronic device provided in this application embodiment also includes a display screen 4;

[0044] The first part 131 is located on the side of the first through hole 11 facing away from the display screen 4.

[0045] In some implementations, the distance between the USB interface 3 and the display screen 4 is usually smaller than the distance between the USB interface and the back cover of the electronic device, such that the width of the first portion 131 along the thickness direction of the electronic device is greater than the width of the second portion 132 along the thickness direction of the electronic device.

[0046] In this embodiment, one of the metal frame portions of the USB interface 3 distributed along the thickness direction of the electronic device, facing away from the display screen 4, is designated as the first part 131. In this way, the wider second part 132 can be used to fix it to the metal frame 2. Compared with the method of fixing it to the metal frame 2 using the narrower metal frame portion, the connection between the metal frame 1 and the metal frame 2 can be effectively strengthened, thereby effectively enhancing the structural strength of the metal frame portion near the USB interface 3.

[0047] As an optional implementation method, such as Figure 4 As shown, there is a second gap 30 between the metal frame 2 and the second segment 14, and the first gap 20 is connected to the second gap 30.

[0048] In this embodiment, the second gap 30 can be used to separate the area of ​​the second segment 14 corresponding to the second gap 30 from the metal frame 2, thereby preventing the projection area of ​​the second gap 30 on the second segment 14 from being grounded, so that the projection area of ​​the second gap 30 on the second segment 14 can serve as an antenna radiator.

[0049] Of course, in some other embodiments, the second gap 30 may not be provided between the second segment 14 and the metal frame 2. In this case, the second segment 14 can be used as the radiator of the slot antenna by opening a slot on the second segment 14.

[0050] As an optional implementation, a second power supply point is provided on the first part 131 of the first segment 13.

[0051] In some embodiments, when a second feed point is provided on the first portion 131, power can be fed to the first portion 131 through the second feed point. In this case, the second segment 14 can be used to form the radiator of the first antenna, and the first portion 131 can be used as the radiator of the second antenna. This increases the number of antennas on the electronic device.

[0052] Optionally, when the first antenna and the second antenna operate at the same frequency, the second antenna can be used to enhance the first antenna, such as by increasing the radiation efficiency of the first antenna or by increasing the radiation range of the first antenna.

[0053] Of course, the first antenna and the second antenna can operate in different frequency bands, which will not be discussed in detail here.

[0054] As an optional implementation, the electronic device further includes a tuning module electrically connected to a first portion 131 of the first segment 13.

[0055] In some implementations, when the first part 131 is electrically connected to the tuning module, the tuning module can be used to adjust the resonant frequency of the first part 131 so that the resonant frequency of the first part 131 is the same as or different from the resonant frequency of the second segment 14.

[0056] If the resonant frequency of the first part 131 is the same as the resonant frequency of the second segment 14, the first part 131 can be used to enhance the radiation efficiency of the second segment 14; if the resonant frequency of the first part 131 is not the same as the resonant frequency of the second segment 14, an additional antenna mode can be constructed.

[0057] It should be noted that the above-mentioned tuning module has the same structure and working principle as the tuning module used in related technologies for adjusting the resonant frequency or operating mode of the radiator, and will not be described again here.

[0058] As an optional implementation method, such as Figure 6 As shown, the electronic device is a foldable screen electronic device, which includes a main body 101 and a secondary body 102, and the main body 101 and the secondary body 102 are hinged together.

[0059] The first through hole 11 and the slit 12 are provided on the metal frame of the main body 101.

[0060] It is worth noting that foldable screen electronic devices have an even more urgent need for thinner and lighter designs. For example, the thickness of foldable screen phones in their unfolded state can reach 4.35mm or even less. In this case, the width of the metal frame 1 along the thickness direction of the foldable screen phone becomes smaller. When the USB port 3 is placed on the side of the foldable screen phone, a first through hole 11 needs to be opened on the metal frame 1, so that the width of the metal frame portion (i.e., the first part 131 or the second part 132) on the side of the USB port 3 along the thickness direction of the foldable screen phone is extremely small. For example, in the foldable screen phones of the related technology, the width of the metal frame portion on the side of the USB port facing the display screen is even less than 0.3mm.

[0061] In this embodiment, in order to use the portion of the metal frame 1 located near the USB interface 3 to form the radiator of the slotted antenna, the first segment 13 of the metal frame 1 with the first through hole 11 is designed in layers to form a first part 131 and a second part 132 distributed on opposite sides of the USB interface 3 along the thickness direction of the electronic device. The first gap 20 is provided only between the first part 131 and the metal frame 2, while the side of the second part 132 is fixedly connected to the metal frame 2. In this way, the fixed connection between the second part 132 and the metal frame 2 can be used to strengthen the structural strength of the metal frame 1 in this area, and the first part 131 is used as the antenna radiator.

[0062] As an optional implementation method, such as Figure 3 As shown, the first through hole 11 includes a first sub-through hole 111 and a second sub-through hole 112, and the USB interface 3 is embedded in the first sub-through hole 111;

[0063] The second sub-through hole 112 is connected to the first sub-through hole 111 and is distributed along the extension direction of the first side 10.

[0064] In some implementations, the number of second sub-vias 112 may be one or two.

[0065] When there is only one second sub-through hole 112, the second sub-through hole 112 can be located on the side of the first sub-through hole 111 facing the fracture 12, or the second sub-through hole 112 can be located on the side of the first sub-through hole 111 facing away from the fracture 12, without being specifically limited here.

[0066] When there are two second sub-through holes 112, a second sub-through hole 112 can be provided on the side of the first sub-through hole 111 facing the fracture 12 and on the side of the first sub-through hole 111 away from the fracture 12.

[0067] For ease of explanation, such as Figure 3 As shown in the embodiment of this application, an example is given by setting a second sub-through hole 112 on the side of the first sub-through hole 111 facing the fracture 12 and on the side of the first sub-through hole 111 away from the fracture 12. This does not constitute a specific limitation.

[0068] In some embodiments, the length of the first portion 131 is the sum of the lengths of the first sub-through hole 111 and the second sub-through hole 112 along the extension direction of the first side 10.

[0069] Since the size of the USB interface 3 needs to meet the USB standard, the size of the first sub-via 111 is fixed. However, antennas with different radiation frequencies require radiators of different sizes. In this embodiment, the size of the first part 131 along the length of the first side 10 can be flexibly adjusted by designing the size of the second sub-via 112 along the length of the first side 10, thereby adjusting the resonant frequency of the first part 131 so that the resonant frequency of the first part 131 meets the design requirements.

[0070] In some embodiments, the width of the second sub-via 112 along the thickness direction of the electronic device is the same as the width of the first sub-via 111 along the thickness direction of the electronic device.

[0071] In some embodiments, the width of the second sub-via 112 along the thickness direction of the electronic device is smaller than the width of the first sub-via 111 along the thickness direction of the electronic device.

[0072] In some embodiments, the width of the first sub-through hole 111 along the thickness direction of the electronic device is determined by the size of the USB interface 3 to be embedded, such as the inner wall of the first sub-through hole 111 being interference-fitted with the outer wall of the USB interface 3.

[0073] It should be noted that the width of the metal frame 1 along the thickness direction of the electronic device is constant. The smaller the width of the second sub-through hole 112 along the thickness direction of the electronic device, the larger the width of the first part 131 along the thickness direction of the electronic device.

[0074] In this embodiment, by reducing the width of the second sub-through hole 112 along the thickness direction of the electronic device, the width of the first part 131 along the thickness direction of the electronic device can be increased, thereby increasing the size of the first part 131, so as to improve the radiation efficiency of the first part 131 as an antenna radiator and improve the structural strength of the first part 131.

[0075] It should be noted that at least one of the gap 12, the first gap 20, the second gap 30, and the second sub-through hole 112 in the embodiments of this application can be filled with insulating dielectric material. In this way, the structural strength of the metal frame 1 and the metal frame 2 can be strengthened, and the integrity of the appearance of the electronic device can be guaranteed.

[0076] As an optional implementation, when the second segment 14 obtains the excitation signal from the first feed point 141, the second segment 14 constitutes the main radiator of the antenna, and the first part 131 of the first segment 13 constitutes the parasitic radiator of the antenna and is coupled to the main radiator of the antenna through the gap 12.

[0077] The radiation frequency of the main radiator of the antenna is a first frequency, and the radiation frequency of the parasitic radiator of the antenna is a second frequency.

[0078] In some implementations, the radiation frequency of the antenna parasitic radiator is inconsistent with the radiation frequency of the antenna main radiator, that is, the first frequency and the second frequency are different. In this case, the antenna parasitic radiator can increase the overall antenna's operating modes, such as increasing the operating frequency band.

[0079] In other embodiments, the radiation frequency of the antenna parasitic radiator is the same as the radiation frequency of the antenna main radiator, that is, the first frequency and the second frequency are the same. In this case, the antenna parasitic radiator can improve the overall radiation efficiency of the antenna.

[0080] For example: Figure 2 In the illustrated electronic device, the second segment 14 serves as the main radiator of the antenna, and the first part 131 serves as the parasitic radiator. The radiation frequency of the parasitic radiator is the same as that of the main radiator. In this case, the radiation efficiency of the antenna formed by the main radiator and the parasitic radiator is... Figure 7 As shown in curve A1, the radiation efficiency of antennas that do not have a gap near the USB interface 3 in related technologies is... Figure 7 As shown in curve A2, by comparing curves A1 and A2, it can be seen that, Figure 2 In the electronic device shown, the antenna parasitic radiator composed of the first part 131 significantly improves the antenna radiation efficiency.

[0081] For example: Figure 6 In the illustrated electronic device, the second segment 14 serves as the main radiator of the antenna, and the first part 131 serves as the parasitic radiator. The radiation frequency of the parasitic radiator is the same as that of the main radiator. In this case, the radiation efficiency of the antenna formed by the main radiator and the parasitic radiator is... Figure 8 As shown in curve B1, the radiation efficiency of antennas that do not have a gap near the USB interface 3 in related technologies is... Figure 8 As shown in curve B2, by comparing curves B1 and B2, it can be seen that... Figure 6 In the electronic device shown, the antenna parasitic radiator composed of the first part 131 significantly improves the antenna radiation efficiency.

[0082] In some implementations, to ensure that the radiation frequency of the parasitic radiator of the antenna is consistent with or inconsistent with the radiation frequency of the main radiator of the antenna, this can be achieved by designing the dimensions of the first part 131, and / or by providing a tuning module electrically connected to the first part 131 to adjust the resonant frequency of the first part 131.

[0083] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0084] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
