DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0040] In recent years, with the rapid development of electronic communication technology, users have higher and higher requirements for the signal quality and communication experience of electronic devices such as mobile phones that can be used for communication. As an important component for achieving communication, the design of antennas in electronic devices and middle frame components has become increasingly critical. However, the available space inside electronic devices and middle frame components is occupied by more and more different electrical components, and the middle frame components using related technologies have space or structural limitations.

[0041] For example, a connection is usually established between the antenna radiator and a peripheral circuit such as a circuit board disposed on the bottom plate of the middle frame assembly by using a connector extending in a direction perpendicular to the antenna radiator and a spring sheet disposed between the bottom plate and the connector. However, since the electrical components also disposed on the bottom plate occupy part of the space where the upper frame of the antenna radiator is located, the space at the upper frame of the antenna radiator is limited, and it is difficult to dispose the spring sheet at the original upper frame position. The structure or position of the antenna radiator itself needs to be changed to realize the connection between the antenna radiator and the circuit board, sacrificing the performance of the antenna radiator itself.

[0042] Based on this, an exemplary embodiment of the present disclosure provides a middle frame assembly, which is provided with a connecting structure, one end of which is connected to the first antenna radiator, the connecting structure passes through the space between the first antenna radiator and the first electrical device and bends toward the second electrical device, and the other end of the connecting structure is electrically connected to the second electrical device. The connecting structure can make the upper frame position of the first antenna radiator avoid the first electrical device that is relatively arranged, while ensuring the antenna performance of the first antenna radiator, solving the problem of space limitation caused by the first electrical device, so as to facilitate the connection of the first antenna radiator with the peripheral circuit.

[0043] In an exemplary embodiment, reference Figure 1 As shown, a middle frame assembly is provided, which can be used to connect the front and rear housings of electronic devices such as mobile phones, and fix first electrical components 40 such as batteries and cameras. The middle frame assembly includes a first middle frame 10, and the first middle frame 10 includes a first bottom plate 20, a first electrical component 40, a second electrical component, a first frame 30 and a connecting structure 50. The first electrical component 40 and the second electrical component are arranged on the first bottom plate 20. Figure 1 In the illustrated embodiment, the first electrical device 40 is a battery.

[0044] The first frame 30 is arranged around at least part of the edge of the first bottom plate 20. The first frame 30 may be arranged around the entire edge of the first bottom plate 20, or around part of the edge of the first bottom plate 20. Exemplarily, the first frame 30 is arranged non-contacting with the first bottom plate 20 and the inner side of the first frame 30 is perpendicular to the first bottom plate 20. The first frame 30 is provided with a first antenna slit 31, and the first antenna slit 31 can disconnect the continuous first frame 30, so that the first frame 30 on one side separated by the first antenna slit 31 constitutes a first antenna radiator 32, and the first antenna radiator 32 is used to transmit and receive antenna signals. The first antenna radiator 32 may be the entire first frame 30 on one side separated by the first antenna slit 31, and the first antenna radiator 32 may also be a part of the first frame 30 disconnected by the first antenna slit 31 and other antenna slits on one side.

[0045] The first electrical device 40 and the second electrical device are arranged side by side along the extension direction of the first antenna radiator 32. For example, when the electronic device where the middle frame assembly is located is in a vertical posture in normal use, the second electrical device is located above the first electrical device 40 in the vertical direction. At least part of the structure of the first antenna radiator 32 is arranged opposite to the first electrical device 40, and the first antenna radiator 32 and the second electrical device are arranged staggered, so that there is a certain space between the first antenna radiator 32 and the first electrical device 40. When the space between the first antenna radiator 32 and the first electrical device 40 is small, that is, when the vertical distance between the first electrical device 40 and the first antenna radiator 32 is short, the upper frame position of the first antenna radiator 32 cannot be arranged in the space between the first antenna radiator 32 and the first electrical device 40 due to space limitations.

[0046] The connecting structure 50 is a conductive material, and one end of the connecting structure 50 is connected to the area on the first antenna radiator 32 that is opposite to the first electrical device 40, that is, one end of the connecting structure 50 is located in the space between the first antenna radiator 32 and the first electrical device 40 where the upper frame position cannot be set. The connecting structure 50 passes through the space between the first antenna radiator 32 and the first electrical device 40 and bends toward the direction of the second electrical device. The other end of the connecting structure 50 is electrically connected to the second electrical device. The connecting structure 50 can make the upper frame position of the first antenna radiator 32 avoid the first electrical device 40 that is relatively set.

[0047] It should be noted that the upper frame position of the first antenna radiator 32 should be within the range of the peripheral circuit so that the first antenna radiator 32 can be connected to the peripheral circuit such as a circuit board. By way of example, the other end of the connecting structure 50 can be connected to an elastic sheet provided on the circuit board to achieve the connection between the first antenna radiator 32 and the circuit board.

[0048] In this embodiment, one end of the connection structure 50 is connected to the first antenna radiator 32, the connection structure 50 passes through the space between the first antenna radiator 32 and the first electrical device 40 and bends toward the second electrical device, and the other end of the connection structure 50 is electrically connected to the second electrical device. The connection structure 50 can make the upper frame position of the first antenna radiator 32 avoid the first electrical device 40 that is relatively arranged, while ensuring the antenna performance of the first antenna radiator 32, solve the problem of space limitation caused by the first electrical device 40, so as to facilitate the connection of the first antenna radiator 32 with the peripheral circuit. In some embodiments, reference Figure 1As shown, the connection structure 50 includes a first connection portion 51, a second connection portion 52 and a third connection portion 53. The first end of the first connection portion 51 is connected to the area on the first antenna radiator 32 that is opposite to the first electrical device 40, and the second end of the first connection portion 51 extends to the space between the first antenna radiator 32 and the first electrical device 40. The first end of the second connection portion 52 is connected to the second end of the first connection portion 51, and the second end of the second connection portion 52 extends outside the space between the first antenna radiator 32 and the first electrical device 40. The first end of the third connection portion 53 is connected to the second end of the second connection portion 52, and the third connection portion 53 extends in a direction close to the second electrical device.

[0049] The connection structure 50 is composed of a first connection part 51, a second connection part 52 and a third connection part 53. The first connection part 51, the second connection part 52 and the third connection part 53 can be, for example, a plate-like structure made of the same material. The first end of the first connection part 51 is connected to the area on the first antenna radiator 32 that is opposite to the first electrical device 40, so that one end of the connection structure 50 is connected to the first antenna radiator 32, and the second end of the first connection part 51 extends to the space between the first antenna radiator 32 and the first electrical device 40. The first connection part 51 first leads the upper frame position to the space between the first antenna radiator 32 and the first electrical device 40. The first end of the second connection part 52 is connected to the second end of the first connection part 51, and the second end of the second connection part 52 extends to the outside of the space between the first antenna radiator 32 and the first electrical device 40. The second connection part 52 then leads the upper frame position to the outside of the space between the first antenna radiator 32 and the first electrical device 40. The first end of the third connection part 53 is connected to the second end of the second connection part 52, and the third connection part 53 extends in a direction close to the second electrical device. The third connection part 53 finally leads the upper frame position to a position close to the second electrical device, so that the other end of the connection structure 50 can be electrically connected to the second electrical device.

[0050] In this embodiment, the first end of the first connecting portion 51 is connected to the area on the antenna radiator opposite to the first electrical device 40, the second end of the first connecting portion 51 is connected to the first end of the second connecting portion 52, the second end of the second connecting portion 52 extends to the outside of the space between the first antenna radiator 32 and the first electrical device 40, and the first end of the third connecting portion 53 is connected to the second end of the second connecting portion 52 and extends in a direction close to the second electrical device, so that one end of the connection structure 50 composed of the first connecting portion 51, the second connecting portion 52 and the third connecting portion 53 is connected to the first antenna radiator 32 and passes through the space between the first antenna radiator 32 and the first electrical device 40, and the other end is electrically connected to the second electrical device. The first connection part 51 and the second connection part 52 lead the upper frame position of the first antenna radiator 32 to the space between the first antenna radiator 32 and the first electrical device 40 and outside the space between the first antenna radiator 32 and the first electrical device 40 in turn, and then lead the upper frame position to a position close to the second electrical device through the third connection part 53, avoiding the first electrical device 40 which is arranged opposite to the first antenna radiator 32, thereby solving the problem of limited structure in the space between the first antenna radiator 32 and the first electrical device 40, so as to facilitate the connection between the first antenna radiator 32 and the peripheral circuit.

[0051] In some embodiments, reference Figure 1 As shown, the extension direction of the first connection portion 51 is perpendicular to the first antenna radiator 32 , the extension direction of the second connection portion 52 is parallel to the first antenna radiator 32 , and the extension direction of the third connection portion 53 is perpendicular to the first antenna radiator 32 .

[0052] In this embodiment, the extension direction of the first connection portion 51 is perpendicular to the extension direction of the first antenna radiator 32, that is, the first connection portion 51 extends in a direction away from the first antenna radiator 32. First, the upper frame position of the first antenna radiator 32 is led out to the space between the first antenna radiator 32 and the first electrical device 40 through the first connection portion 51, so that the upper frame position of the first antenna radiator 32 can be located within the range of the first base plate 20, which facilitates the subsequent connection of the first antenna radiator 32 with the circuit board on the first base plate 20. The extension direction of the second connection portion 52 is parallel to the extension direction of the first antenna radiator 32, that is, the second connection portion 52 does not change the vertical distance between the upper frame position and the first antenna radiator 32. After the first connection portion 51 leads the upper frame position of the first antenna radiator 32 to the space between the first antenna radiator 32 and the first electrical device 40, the upper frame position of the first antenna radiator 32 is led out of the space between the first antenna radiator 32 and the first electrical device 40 through the second connection portion 52, solving the problem of limited structure in the space between the first antenna radiator 32 and the first electrical device 40, so as to facilitate the connection between the first antenna radiator 32 and the peripheral circuit. The extension direction of the third connection portion 53 is perpendicular to the first antenna radiator 32, realizing the bending of the connection structure 50 toward the second electrical device, shortening the distance of the electrical connection between the connection structure 50 and the second electrical device. In addition, the extension direction of the first connection part 51 and the extension direction of the third connection part 53 are both perpendicular to the extension direction of the second connection part 52, which can reduce the total length of the first connection part 51 and the second connection part 52 in the extension direction, simplify the structure, and reduce the manufacturing cost.

[0053] In some embodiments, reference Figure 1 As shown, the cross-sectional area of ​​the first connecting portion 51 is greater than the cross-sectional area of ​​the second connecting portion 52 .

[0054] The cross-sectional area of ​​the first connection portion 51 refers to the area of ​​the surface cut on the first connection portion 51 by a surface perpendicular to the extension direction of the first connection portion 51, and the cross-sectional area of ​​the second connection portion 52 refers to the area of ​​the surface cut on the second connection portion 52 by a surface perpendicular to the extension direction of the second connection portion 52. Exemplarily, the first connection portion 51 and the second connection portion 52 are plate-shaped, the cross-section of the first connection portion 51 and the cross-section of the second connection portion 52 are both rectangular, the length of the rectangular cross-section of the first connection portion 51 is the same as the length of the rectangular cross-section of the second connection portion 52, the width of the rectangular cross-section of the first connection portion 51 is greater than the width of the rectangular cross-section of the second connection portion 52, so that the area of ​​the rectangular cross-section of the first connection portion 51 is greater than the area of ​​the rectangular cross-section of the second connection portion 52.

[0055] In this embodiment, by setting the cross-sectional area of ​​the first connection part 51 to be larger than the cross-sectional area of ​​the second connection part 52, the contact area between the first connection part 51 and the first antenna radiator 32 can be made larger, thereby ensuring a reliable connection between the first connection part 51 and the first antenna radiator 32.

[0056] In other embodiments, reference Figure 1 As shown, the dimension of the second connection portion 52 along the first direction is smaller than the dimension along the second direction. The first direction is the relative direction of the first antenna radiator 32 and the first electrical device 40 , and the second direction is perpendicular to the first base plate 20 .

[0057] The relative direction between the first antenna radiator 32 and the first electrical device 40 is taken as the first direction, and the direction perpendicular to the first base plate 20 is taken as the second direction. For example, the first direction is as follows: Figure 1 The X direction is shown, and the second direction is as Figure 1 In the Y direction shown, the dimension of the second connection portion 52 along the first direction is smaller than the dimension of the second connection portion 52 along the second direction. Exemplarily, the second connection portion 52 is plate-shaped, and the cross section of the second connection portion 52 is rectangular. When the dimension of the second connection portion 52 along the first direction is smaller than the dimension of the second connection portion 52 along the second direction, the two sides of the cross section of the second connection portion 52 along the first direction are the short sides of the rectangle, and the two sides of the cross section of the second connection portion 52 along the second direction are the long sides of the rectangle.

[0058] In this embodiment, by setting the size of the second connection portion 52 along the first direction to be smaller than the size along the second direction, the second connection portion 52 can have a smaller size in the relative direction between the first antenna radiator 32 and the first electrical device 40, reducing the space occupied by the second connection portion 52 in the second direction, and facilitating the second connection portion 52 to be arranged in the space between the first antenna radiator 32 and the first electrical device 40, where the space along the second direction is smaller. Furthermore, the upper frame position of the first antenna radiator 32 can be led out of the space between the first antenna radiator 32 and the first electrical device 40 through the second connection portion 52, thereby solving the problem of limited structure in the space between the first antenna radiator 32 and the first electrical device 40, and facilitating the connection between the first antenna radiator 32 and the peripheral circuit.

[0059] In some other embodiments, reference Figure 1 As shown, the cross-sectional area of ​​the first connecting portion 51 is greater than the cross-sectional area of ​​the second connecting portion 52; the dimension of the second connecting portion 52 along the first direction is smaller than the dimension along the second direction, the first direction is the relative direction of the first antenna radiator 32 and the first electrical device 40, and the second direction is perpendicular to the first base plate 20.

[0060] In this embodiment, by setting the cross-sectional area of ​​the first connecting portion 51 to be larger than the cross-sectional area of ​​the second connecting portion 52, a reliable connection between the first connecting portion 51 and the first antenna radiator 32 is ensured, and by setting the dimension of the second connecting portion 52 along the first direction to be smaller than the dimension along the second direction, the space occupied by the second connecting portion 52 in the second direction is reduced, so that the second connecting portion 52 can be conveniently set in the space between the first antenna radiator 32 and the first electrical device 40 where the space along the second direction is smaller.

[0061] It should be noted that when the second connecting portion 52 is arranged in the above manner, Figure 2 As shown, when the first antenna radiator 32 is excited, the current direction in the connection structure 50 formed by the first connection portion 51 and the second connection portion 52 is the same as the current direction of the first antenna radiator 32. Figure 3 As shown, the overall scattering parameters of the connection structure 50 and the first antenna radiator 32 are within the standard range, that is, the plate-shaped second connection portion 52 will not affect the radiation performance of the first antenna radiator 32, so that the connection structure 50 can effectively participate in the radiation process.

[0062] In some embodiments, in the relative direction between the first antenna radiator 32 and the first electrical device 40, the second connection portion 52 is located between the first electrical device 40 and the first edge of the first base plate 20 and the distance between the second connection portion 52 and the first electrical device 40 is greater than the distance between the second connection portion 52 and the first edge of the first base plate 20, and the first edge is located between the first antenna radiator 32 and the first electrical device 40.

[0063] The second connection portion 52 is arranged between the first antenna radiator 32 and the first electrical device 40, and the first edge of the first base plate 20 is also located between the first antenna radiator 32 and the first electrical device 40. In the relative direction of the first antenna radiator 32 and the first electrical device 40, the second connection portion 52 is located between the first electrical device 40 and the first edge of the first base plate 20, and the distance between the second connection portion 52 and the first electrical device 40 is greater than the distance between the second connection portion 52 and the first edge, so that the upper frame position of the first antenna radiator 32 led out through the second connection portion 52 is closer to the first edge and farther away from the first electrical device 40.

[0064] In this embodiment, by setting the distance between the second connecting portion 52 and the first electrical device 40 to be greater than the distance between the second connecting portion 52 and the first edge of the first base plate 20, the upper frame position of the first antenna radiator 32 led out through the second connecting portion 52 can be made closer to the first edge and farther away from the first electrical device 40, thereby making the second connecting portion 52 arranged between the first electrical device 40 and the first antenna radiator 32 as far away from the first electrical device 40 as possible, preventing the first electrical device 40 from interfering with the second connecting portion 52, and improving the stability of the connection between the first antenna radiator 32 and the circuit board.

[0065] In some embodiments, reference Figure 1 As shown, the middle frame assembly further includes a spring sheet 60 , which is disposed between the second electrical device and the other end of the connecting structure 50 in a direction perpendicular to the first base plate 20 .

[0066] The circuit board can be provided on the first base plate 20 as a second electrical device, and the circuit board is used as a peripheral circuit to feed power to the first antenna radiator 32. The spring sheet 60 extends in a direction perpendicular to the first base plate 20, and the two ends of the spring sheet 60 are respectively connected to the second electrical device and the other end of the connection structure 50. Exemplarily, one end of the spring sheet 60 close to the connection structure 50 can be connected to the second end of the third connection portion 53, so that the third connection portion 53 leads the upper frame position of the first antenna radiator 32 out of the space between the first antenna radiator 32 and the first electrical device 40, and then the second electrical device is connected to the first antenna radiator 32 through the spring sheet 60.

[0067] In this embodiment, by setting a spring clip 60 between the second electrical component and the other end of the connecting structure 50, the upper frame position of the first antenna radiator 32 can be led out of the space between the first antenna radiator 32 and the first electrical component 40 by the third connecting portion 53, and then the connection between the second electrical component and the first antenna radiator 32 can be achieved through the spring clip 60, which solves the problem that the spring clip 60 cannot be set in the space between the first antenna radiator 32 and the first electrical component 40, and the first antenna radiator 32 can be fed through the second electrical component and the connecting structure 50 set on the first base plate 20.

[0068] In some embodiments, reference Figure 1 As shown, the first electrical device 40 includes a battery, and the second electrical device includes a circuit board.

[0069] The first electrical device 40 includes a battery disposed on the first base plate 20, and the projection shape of the battery on the first base plate 20 may be, for example, a rectangle. The second electrical device includes a circuit board disposed on the first base plate 20, and a feeding path of the first antenna radiator 32-connection structure 50-spring-circuit board may be formed through the connection structure 50, so as to feed the first antenna radiator 32 through the circuit board as the second electrical device.

[0070] In some embodiments, reference Figure 4 and Figure 5 As shown, the middle frame assembly also includes a second middle frame 70 that can be folded and opened relative to the first middle frame 10, the second middle frame 70 includes a second bottom plate 71 and a second frame 72 arranged around at least a portion of the edge of the second bottom plate 71, a second antenna slit 73 is arranged on the second frame 72, at least a portion of the second frame 72 on one side of the second antenna slit 73 constitutes a second antenna radiator 74, and when the first middle frame 10 and the second middle frame 70 are in a folded state, the first antenna slit 31 and the second antenna slit 73 are aligned.

[0071] When the electronic device including the middle frame assembly is a foldable electronic device, the middle frame assembly also includes a second middle frame 70 that can be folded and opened relative to the first middle frame 10. The first middle frame 10 and the second middle frame 70 can be folded and opened relative to each other through a rotating shaft, for example. The second middle frame 70 includes a second bottom plate 71 and a second frame 72. The second frame 72 is arranged around all or part of the edge of the first bottom plate 20. Exemplarily, the inner side of the second frame 72 is perpendicular to the second bottom plate 71. A second antenna slit 73 is provided on the second frame 72. The second antenna slit 73 can disconnect the continuous second frame 72, so that the second frame 72 on one side separated by the second antenna slit 73 constitutes a second antenna radiator 74, and the second antenna radiator 74 is used to transmit and receive antenna signals. The second antenna radiator 74 can be the entire second frame 72 on one side separated by the second antenna slit 73, and the second antenna radiator 74 can also be a portion of the second frame 72 disconnected by the second antenna slit 73 and other antenna slits on one side.

[0072] Due to the setting of the connecting structure 50, the upper frame position of the first antenna radiator 32 can be led out of the space between the first antenna radiator 32 and the first electrical device 40 to outside the space between the first antenna radiator 32 and the first electrical device 40, and the connection between the first antenna radiator 32 and the first base plate 20 can be achieved without changing the position of the first antenna slit 31. Therefore, when the first middle frame 10 and the second middle frame 70 are in a folded state, that is, when the first middle frame 10 and the second middle frame 70 are in contact or the relative distance is the smallest, the first antenna slit 31 and the second antenna slit 73 can be aligned.

[0073] In this embodiment, by providing a second middle frame 70 that can be folded and opened relative to the first middle frame 10, a portion of the second frame 72 included in the second middle frame 70 constitutes a second antenna radiator 74, thereby achieving the arrangement of multiple antenna radiators in the middle frame assembly. When the first middle frame 10 and the second middle frame 70 are in a folded state, the first antenna slit 31 and the second antenna slit 73 are aligned to ensure the radiation performance of the first antenna radiator 32 and the second antenna radiator 74, while preventing the first antenna slit 31 and the second antenna radiator 73 from being misaligned in the folded state to affect the appearance of the middle frame assembly and the electronic device including the middle frame assembly.

[0074] In some embodiments, the first antenna radiator 32 and the second antenna radiator 74 are respectively used to form different low-frequency antennas.

[0075] The first antenna radiator 32 and the second antenna radiator 74 are both used to form a low-frequency antenna, so that the middle frame assembly includes a plurality of low-frequency antennas. The frequency of the low-frequency antenna may be within the range of 650 to 1000 MHz, for example.

[0076] The electrical length is a parameter to measure the electrical performance of the antenna. The electrical length is the geometric length of the antenna and the wavelength of the electromagnetic wave transmitted by the antenna. For a low-frequency antenna, the wavelength of the electromagnetic wave transmitted by the antenna is longer, so the actual geometric length of the low-frequency antenna is also longer, that is, the dimensions of the first antenna radiator 32 and the second antenna radiator 74 along their extension direction are larger. Therefore, when the first antenna radiator 32 and the second antenna radiator 74 constitute a low-frequency antenna, the first antenna radiator 32 with a longer length is more likely to have the problem of limited upper frame position as mentioned above, and the upper frame position of the first antenna radiator 32 needs to be led out of the space between the first antenna radiator 32 and the first electrical device 40 through the connection structure 50. The first antenna radiator 32 and the second antenna radiator 74 constitute different low-frequency antennas, and the low-frequency antenna formed by the first antenna radiator 32 and the low-frequency antenna formed by the second antenna radiator 74 can be set to have similar electrical lengths.

[0077] In this embodiment, the low-frequency antenna can be used in a wide coverage scenario due to its wide coverage and low propagation loss. Different low-frequency antennas are formed by the first antenna radiator 32 and the second antenna radiator 74, so that the middle frame assembly can include multiple low-frequency antennas, which improves the propagation performance of the middle frame assembly for low-frequency signals, thereby improving the signal quality and communication experience.

[0078] In some embodiments, reference Figure 5 As shown, the first antenna radiator 32 is located at the lower side of the first antenna slit 31 and is in a straight line, and the second antenna radiator 74 is located at the upper side of the second antenna slit 73 and is in an L shape.

[0079] The middle frame assembly may also include a screen, for example. Based on the orientation of the user facing the screen, the first antenna radiator 32 is constituted by the first frame 30 which is in a straight line at the lower side of the first antenna slit 31, so that the first antenna radiator 32 constituted by the first frame 30 and a part of the side frame is located at the lower side of the first antenna slit 31 and the first antenna radiator 32 is in a straight line. The second antenna radiator 74 is constituted by the second frame 72 which is in an L shape at the upper side of the second antenna slit 73, so that the second antenna radiator 74 which is constituted by the second frame 72 and a part of the top frame and a part of the side frame is located at the upper side of the second antenna slit 73 and the second antenna radiator 74 is in an L shape.

[0080] In this embodiment, by setting the first antenna radiator 32 to be located at the lower side of the first antenna break 31 and to be in a straight line, and setting the second antenna radiator 74 to be located at the upper side of the second antenna break 73 and to be L-shaped, when the first middle frame 10 and the second middle frame 70 are in a folded state, the first antenna radiator 32 and the second antenna radiator 74 can be isolated from each other, thereby avoiding the first antenna radiator 32 and the second antenna radiator 74 from overlapping and interfering with each other, thereby ensuring the performance of the first antenna radiator 32 and the second antenna radiator 74.

[0081] In some embodiments, reference Figure 5 As shown, part of the top frame of the first frame 30 constitutes the third antenna radiator 80, and the third antenna radiator 80 is straight; part of the bottom frame and part of the side frame of the second frame 72 constitute the fourth antenna radiator 90, and the fourth antenna radiator 90 is L-shaped; the third antenna radiator 80 and the fourth antenna radiator 90 are respectively used to form different low-frequency antennas.

[0082] Based on the orientation when the user is facing the screen, part of the top frame of the first frame 30 constitutes a linear third antenna radiator 80, and part of the bottom frame and part of the side frame of the second frame 72 constitute an L-shaped fourth antenna radiator 90. The third antenna radiator 80 and the fourth antenna radiator 90 constitute different low-frequency antennas, and together with the low-frequency antenna formed by the first antenna radiator 32 and the second antenna radiator 74, they form a 4*4 multiple input multiple output (MIMO) low-frequency antenna architecture with 4 inputs and 4 outputs.

[0083] In this embodiment, a third antenna radiator 80 in a straight line is formed by a portion of the top frame of the first frame 30, and a fourth antenna radiator 90 in an L shape is formed by a portion of the bottom frame and a portion of the side frame of the second frame 72, and the first frame 30 of the first middle frame 10 and the second frame 72 of the second middle frame 70 are fully utilized to form the third antenna radiator 80 and the fourth antenna radiator 90 for forming different low-frequency antennas. The low-frequency antenna formed by the third antenna radiator 80 and the fourth antenna radiator 90 and the low-frequency antenna formed by the first antenna radiator 32 and the second antenna radiator 74 form a 4*4 multi-near and multi-out low-frequency antenna architecture, which improves the signal quality and communication experience of the low-frequency signal.
