[0022] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0024] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0025] It should also be pointed out that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0026] In recent years, terminal devices have come in more and more forms, but many of them have relatively compact internal spaces, leaving little design space for antennas. Terminal devices with double-sided or multi-sided screens, such as foldable screen mobile phones, are increasingly popular among consumers. A double-sided screen refers to a terminal device with two screens that can be operated independently of each other. The double-sided screen design can provide more interactive functions. In folding mode, there are more and more applications on double-sided screen terminal devices. The most notable feature is that there is a large secondary screen on the back of the terminal device, which provides users with many interesting application experiences after the phone is folded.

[0027] However, the addition of a secondary screen is not conducive to antenna design. The secondary screen will take up space on the back, and generally speaking, the antenna in the terminal device radiates in all directions, and metal should be avoided as much as possible within its clearance area. The secondary screen generally contains metal materials such as a backlight, and the electrical radiation frequency band generated by its operation will also radiate the working frequency band of the antenna, which is equivalent to a metal layer. It is easy to absorb and degrade the signal radiated by the antenna, affecting the performance of the antenna. In addition, other noise reduction parts such as batteries, oscillators, shielding covers, cameras, metal frames, etc. will reflect, absorb and offset the electromagnetic wave signals of the antenna, which results in the space left for the antenna to be placed more limited, greatly reducing the antenna design space and increasing the difficulty of antenna design. The emergence of full-screen terminal devices has also further compressed the clearance area of ​​the antenna. However, as a key component of the terminal device, the deployment of the antenna must adapt to this space limitation. Therefore, it is necessary to seek an antenna deployment solution that maximizes the use of this limited space in the case of space in the terminal device. For example, Figure 1 is a schematic diagram of a terminal device. Figure 1 As shown, due to the obstruction of the secondary screen 101, the antenna in the terminal device can only be set at the edge of the terminal device that is not obstructed by the secondary screen 101, that is, the position outside the dotted line and within the frame of the terminal device.

[0028] As for antennas that are mainly designed to rely on the back space of the terminal device, that is, antennas with a radiation direction toward the back of the mobile terminal, that is, the side where the camera is located, and with low transmission power, such as ultra-wideband antennas (Ultra-Wideband, UWB), UWB antennas play a very critical role in small-scale positioning systems and can provide high-precision location information, for example, providing users with positioning search functions. Moreover, since the operating frequency of the UWB antenna is different from that of other antennas, other antennas cannot be used to replace the function of the UWB antenna. In actual applications, due to the masking of the secondary screen of the double-sided screen, this type of antenna cannot achieve the performance of the antenna. Therefore, in one implementation method, this type of antenna is not provided in the terminal device of the double-sided screen, which reduces the functions that can be realized by the terminal device.

[0029] In one solution, Figure 2 Schematic diagram of antenna setting for a terminal device Figure 1 .like Figure 2 As shown, the display area of ​​the secondary screen 101 in the terminal device can be reduced so that the signal radiated by the antenna 102 is not blocked by the secondary screen 101. However, this solution will reduce the display area of ​​the secondary screen 101, thereby affecting the application and user experience of the secondary screen 101, which is inconsistent with the current design concept of full screen.

[0030] In another solution, the full-screen design of the secondary screen can be maintained, but the secondary screen can be partially opened. That is, by reducing the display electrodes on the secondary screen near the antenna, as well as metal materials such as the backlight, the effect of the secondary screen on the radiation characteristics of the antenna is weakened. However, this solution reduces the brightness of the secondary screen near the antenna, such as the display electrodes and backlight, and affects the display effect. Moreover, the secondary screen requires customized design, which greatly increases the design cost of the secondary screen.

[0031] In another solution, Figure 3 Schematic diagram of antenna setting for a terminal device Figure 2 .like Figure 3 As shown, the display area of ​​the secondary screen 101 can also be reduced to a partial display, and the antenna 102 can be set in other areas where the secondary screen 101 is not set, and is not blocked by the secondary screen 101. However, this greatly reduces the display area of ​​the secondary screen 101, affecting the user experience.

[0032] Based on this, an embodiment of the present application provides an electronic device, in which a radiator is arranged in a containing space formed by a first component and a second component, and the first component and the second component both affect the electromagnetic wave signal radiated by the radiator. The target side of the radiator is close to the shell of the electronic device, so that the electromagnetic wave signal of the radiator is directed in the direction of the shell, and then radiated outside the electronic device. The side of the radiator away from the target side is grounded through the first connecting part, which can further enhance the intensity of the electromagnetic wave signal. Therefore, without changing the first component and the second component, the influence of the first component and the second component on the intensity of the electromagnetic wave signal radiated by the radiator is avoided, thereby improving the performance of the radiator.

[0033] The present application is further described in detail below through the accompanying drawings and specific embodiments.

[0034] In one embodiment of the present application, Figure 4 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 1 .like Figure 4 As shown, the electronic device 20 may include:

[0035] The radiator 203 is used to radiate electromagnetic wave signals;

[0036] The first component 201 and the second component 202 are arranged opposite to each other, and the portion where the plane of the first component 201 is parallel to the plane of the second component 202 forms an accommodation space. The radiator 203 is arranged in the accommodation space, close to the target side of the first component 201 and the second component 202, and the target side is the side of the first component 201 and the second component 202 close to the shell;

[0037] A side of the radiator 203 away from the target side is grounded through the first connecting portion 204;

[0038] The first component 201 and the second component 202 are components that affect the radiator 203 to radiate electromagnetic wave signals.

[0039] In the embodiment of the present application, the first component 201 and the second component 202 are arranged opposite to each other, and the first component 201 is parallel to the second component 202. The first component 201 and the second component 202 can be components of a plane or other shapes in the electronic device 20, which are made of metal material or other materials that have the ability to shield the radiator 203. When the electromagnetic wave signal of the radiator 203 radiates to the first component 201 or the second component 202, the first component 201 or the second component 202 can absorb or even shield the electromagnetic wave signal, causing the electromagnetic wave signal to attenuate to the point where it cannot penetrate, thereby achieving the effect of shielding the signal of the radiator 203 in the direction of the first component 201 and the second component 202. It should be noted that, in general, the projection area of ​​the first component 201 and the second component 202 to the radiator 203 is larger than that of the radiator 203, thereby shielding the electromagnetic wave signal radiated upward or downward by the radiator 203.

[0040] In the embodiment of the present application, the radiator 203 may refer to a device that can radiate electromagnetic wave signals, and the transmission power of the electromagnetic wave signals is low, and can be easily shielded by the first component 201 and the second component 202, such as an antenna. In some embodiments, it may be a UWB antenna.

[0041] In the embodiment of the present application, the first connection part 204 may be a component made of metal or other conductive materials, and the potential of the first connection part 204 itself may be ground, or after being connected to other components with ground potential, it is fixedly connected to the side of the radiator 203 away from the target side. The shape of the first connection part 204 may be determined according to the shape of the radiator 203, and is not specifically limited here.

[0042] It should be noted that the first component 201 is parallel to the second component 202, and the side of the first component 201 and the second component 202 that is parallel to each other and close to the housing of the electronic device is the target side of the first component 201 and the target side of the second component 202. In this way, the overlapping part of the first component 201 and the second component 202 along their parallel vertical projections, that is, the mutually parallel part between the first component 201 and the second component 202, can form an accommodating space, the height of which is determined by the distance between the first component 201 and the second component 202, and the upper surface area and the lower surface area of ​​the space are determined by the area of ​​the overlapping part of the first component 201 and the second component 202. It should be noted that the parameter values ​​of the length, width and height of the space should be greater than the corresponding parameter values ​​of the radiator 203.

[0043] After the radiator 203 is arranged in the accommodation space, as mentioned above, due to the shielding of the electromagnetic wave signal radiated by the radiator 203 by the first component 201 and the second component 202, the electromagnetic wave signal radiated by the radiator 203 can only be radiated in the direction other than the first component 201 and the second component 202. In the embodiment of the present application, the target side of the first component 201 and the second component 202 is close to the shell of the electronic device 20, and one side of the radiator 203 can be fixed on the shell of the electronic device 20 on the side where the target side is located, so that the electromagnetic wave signal radiated by the radiator 203 can be directed to the direction of the shell of the electronic device 20, and radiated to the outside of the electronic device 20 when the shell of the electronic device 20 is made of a material that does not interfere with the electromagnetic wave signal.

[0044] It should be noted that, based on the above, the other side of the radiator 203 away from the target side can also radiate electromagnetic wave signals to the side away from the shell, which is generally the inside of the electronic device 20. Before the electromagnetic wave signals reach the shell on the other side of the electronic device 20 and radiate out of the electronic device 20, there may be other components that affect the electromagnetic wave signals. Therefore, the side of the radiator 203 away from the target device can be grounded through the first connecting portion 204, so that the radiator 203 and the first connecting portion 204 connecting side can be short-circuited, thereby suppressing the electromagnetic wave signals radiated by the radiator 203 to the side away from the target side, and then the energy of the radiator 203 passes through the part on the same side as the target side, passes through the shell of the electronic device 20, and radiates to the outside of the electronic device 20, thereby strengthening the intensity of the electromagnetic wave signals. Without changing the structures of the first component 201 and the second component 202, the intensity of the electromagnetic wave signals of the radiator 203 reaches an intensity similar to that when it is not blocked by the first component 201 and the second component 202.

[0045] It should be understood that the target side of the first component 201 can be any side of the first component 201, and the target side of the second component 202 can be a side parallel to the target side of the first component 201. Accordingly, the side of the housing of the electronic device 20 close to the target side is also determined according to the positions of the side of the first component 201 and the side of the second component 202.

[0046] It should also be noted that the embodiment of the present application does not specifically limit the position of the radiator 203 in the accommodating space. The radiator 203 in the accommodating space only needs to have one side close to or fixed to the shell where the target side is located, and the other side is fixed on the first connecting portion 204.

[0047] An embodiment of the present application provides an electronic device, in which a radiator is arranged in a containing space formed by a first component and a second component, and the first component and the second component both affect the electromagnetic wave signal radiated by the radiator. The target side of the radiator is close to the shell of the electronic device, so that the electromagnetic wave signal of the radiator is directed in the direction of the shell and then radiated outside the electronic device. The side of the radiator away from the target side is grounded through the first connecting part, which can further enhance the intensity of the electromagnetic wave signal. Therefore, without changing the first component and the second component, the influence of the first component and the second component on the intensity of the electromagnetic wave signal radiated by the radiator is avoided, thereby improving the performance of the radiator.

[0048] In yet another embodiment of the present application, the first component and the second component are both display screens.

[0049] In the embodiments of the present application, Figure 5 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 2 .like Figure 5 As shown, illustratively, the first component 201 may be a display screen, such as a full-screen display screen, which may correspond to the main display screen of the electronic device, that is, the display screen on the front of the electronic device; the second component is arranged opposite to the first component, Figure 5 This is a schematic diagram of the front of the electronic device, and the second component on the back of the electronic device is not shown. The second component can be a secondary display screen, such as a folding screen, or a screen on the back of an electronic device with a folding function and a camera, which can be set on the entire back or only on a part of the back of the electronic device. It should be understood that the two display screens are arranged opposite to each other, and each display screen includes metal materials such as display electrodes and backlight sheets, wherein the type of display screen is not specifically limited here.

[0050] It should be noted that, when both the first component and the second component are display screens, the two display screens of the electronic device are arranged opposite to each other to form a housing space, and a radiator is arranged inside. Since the chip responsible for information processing in the electronic device is arranged on the secondary screen, that is, on the side of the second component, the radiator is generally also arranged on the side of the housing space close to the second component.

[0051] In some embodiments, the electronic device includes a first body and a second body, and the first body and the second body can rotate relative to each other;

[0052] The first component covers the first surface of the first body and the second surface of the second body;

[0053] The second component covers the third surface of the second body;

[0054] The first surface and the second surface are located at the same side of the first body and the second body, and the third surface is located at the opposite side of the second surface.

[0055] The first body may be a component below the rotating shaft mechanism, and the second body may be a component above the rotating shaft mechanism. The first body and the second body are rotatably connected via the rotating shaft mechanism.

[0056] In the embodiments of the present application, Figure 6 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 3 .like Figure 6 As shown, for example, the first surface of the first body and the second surface of the second body can both be the front of the electronic device, and the first component can be a foldable flexible display screen. Figure 6 In the folded state of the electronic device shown, the first component is bent inwards, so that the electronic device is converted between a larger size and a smaller size. In this case, the first surface of the first body and the second surface are attached to each other. The third surface of the second body can be the back of the electronic device, and the plane where the camera is located is set above the hinge mechanism, such as Figure 6 As shown, the second component can be covered on the third surface of the second body, and an accommodation space is formed between the second component and the first component covered on the second surface of the second body to deploy the radiator.

[0057] It should be noted that the second component may also cover the fourth surface of the first body, the fourth surface is opposite to the first surface, and the radiator is arranged between the second component on the fourth surface of the first body and the first component on the first surface.

[0058] It should be noted that in the embodiment of the present application, since the main board, chip, etc. are generally arranged in the area where the first body is located, the radiator can also be arranged in the accommodation space formed by the first component and the second component on both sides of the second body. Being on the same side as the chip can avoid transmission loss caused by over-axis.

[0059] The embodiment of the present application provides an electronic device, wherein the first component and the second component are both display screens, and the electronic device includes a first body and a second body, the first component covers the first surface of the first body and the second surface of the second body, and the second component covers the third surface of the second body. In this way, the radiator is located in the accommodation space formed between the front display screen and the back display screen of the electronic device, and under the aforementioned structure, not only its performance is maintained unaffected, but also the structure of the display screen is not affected, thereby reducing the cost of the electronic device.

[0060] In another embodiment of the present application, the electronic device also includes a shell, the shell includes a frame, the frame is located between the first component and the second component, and there is a gap between the frame and the first component and / or the second component so that the electromagnetic wave signal of the radiator can be radiated outward through the gap.

[0061] For example, Figure 7A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 4 .like Figure 7 As shown, the second component 202 is a display screen on the back of the electronic device 20, and a gap exists between the second component 202 and the frame 2051 as an example for explanation.

[0062] In the embodiment of the present application, the housing of the electronic device 20 refers to the outer shell of the electronic device 20, including the frame between the two display screens. The frame 2051 may be a metal material that has a shielding and absorbing effect on electromagnetic wave signals, which is not specifically limited here.

[0063] like Figure 7 As shown, the side of the second component 202 close to the frame of the electronic device 20 is the target side. There is a gap between the target side and the frame close to the target side. The size of the gap is not limited here and is specifically determined according to the design size of the shell and the display screen.

[0064] It should be noted that when the electronic device 20 is placed flat on a desktop, the shorter direction of the display screen is the X-axis, and the direction perpendicular to the desktop is the Z-axis. Figure 7 is a schematic diagram of the electronic device in the XOZ plane. Figure 7 As shown, one side of the radiator 203 is close to the target side, and can be fixed in the frame 2051 of the shell close to the target side, and the side of the radiator 203 away from the target side can be connected to the first connection part 204 and grounded through the first connection part 204. In this way, the electromagnetic wave signal radiated by the radiator 203 can be radiated to the outside of the electronic device 20 through the gap between the target side of the second component 202 and the frame 2051 close to the target side. In addition, since the other end of the radiator 203 is grounded through the first connection part 204, the side of the radiator 203 away from the target side is short-circuited, and all electromagnetic wave signals of the radiator 203 can only be radiated outward through the gap on the side where the target side is located, thereby achieving the effect of enhancing the electromagnetic wave signal radiated by the radiator 203 through the gap.

[0065] It should also be noted that the above Figure 7 The description is made by taking the case where the radiator is close to the second component in the accommodation space as an example. In some embodiments, the radiator may be close to the first component in the accommodation space, and there may be a gap between the first component and the frame. Alternatively, when the radiator is centered in the accommodation space, there may be gaps between the first component and the second component and the frame, so that the electromagnetic wave signal may radiate outward through at least one of the gaps.

[0066] The embodiment of the present application provides an electronic device, the electronic device includes a housing, the housing includes a frame, and there is a gap between the first component and / or the second component and the frame. In this way, when the frame is made of a material that has a shielding effect on electromagnetic wave signals, the structure of the first component and the second component is not changed, and the radiator can still radiate the electromagnetic wave signal outward, thereby ensuring the stable performance of the radiator.

[0067] In some embodiments, continue to refer to Figure 7 The electronic device further includes a metal plate 206 , wherein the metal plate 206 is disposed below the radiator 203 and parallel to the radiator 203 , and is connected to the first connecting portion 204 as an equivalent ground.

[0068] In the embodiment of the present application, the metal plate 206 may be a metal component such as a main board in the electronic device 20 or a printed circuit board (PCB) for realizing other functions, and is equivalent to the ground terminal relative to the radiator 203 .

[0069] In the embodiments of the present application, Figure 7 As shown, in the case where the radiator 203 is a UWB antenna, the radiator 203 is a rectangular sheet structure, the metal plate 206 is arranged below the electronic device 20, parallel to the plane formed by the radiator 203, and the first connecting portion 204 can be a metal strip parallel to the side of the radiator 203 away from the target side, the upper side of the metal strip is connected to the side of the radiator 203 away from the target side, and the lower side of the metal strip is connected to the metal plate 206, which is used to connect the side of the radiator 203 away from the target side to the ground.

[0070] Figure 8 A radiation direction diagram provided in an embodiment of the present application Figure 1 .in, Figure 8 (a) is a schematic diagram of the radiation direction when the first connection portion is not provided and the side of the radiator away from the target side is not connected to the metal plate. The radiator has two symmetrical radiation ends on the left and right sides. The two radiation ends are superimposed together, and because of the left-right symmetry, a vertically upward radiation pattern is formed. Figure 8(b) is the radiation direction when the side of the radiator away from the target side is connected to the metal through the first connection part. In this case, the left half of the radiator, that is, the side away from the target side, is equivalent to grounding, so that the end of this side of the radiator is short-circuited, which suppresses the energy radiated to the left by the radiator. The energy on the left side cannot be radiated out, and can only be radiated outward through the right half of the radiator, that is, the radiation end close to the target side. In this way, all electromagnetic wave signals in the radiator are radiated outward toward the target side, so that the radiation field pattern is biased toward one side of the target side. In this way, not only the electromagnetic wave signal of the radiator is enhanced to a similar intensity when it is not blocked, but also the part of the radiator close to the first connection part can be reduced, thereby reducing the size of the radiator.

[0071] The embodiment of the present application provides an electronic device, which sets a metal plate as an equivalent ground, and connects a radiator to the metal plate through a first connection portion. In this way, the radiation field pattern of the radiator can be changed, so that the side of the radiator where the first connection portion is located is short-circuited, and the electromagnetic wave signal radiated by the other side of the radiator close to the target side is enhanced, thereby improving the intensity of the electromagnetic wave signal radiated outward by the radiator.

[0072] In another embodiment of the present application, the electronic device further includes a second connecting portion; wherein:

[0073] The second connection portion is arranged in the space between the first component and the metal plate, and two sides of the second connection portion are respectively connected to the first component and the metal plate.

[0074] In an embodiment of the present application, the second connecting part may be a conductive foam, and the first component may be a main display screen of an electronic device. When the radiator is arranged below the first component and above the metal plate, the second connecting part may be filled in the space between the first component and the metal plate to connect the metal plate and the first component, so that the metal plate and the first component maintain the same potential.

[0075] As mentioned above, since the first component contains metals such as electrodes and backlight sheets, the first component can be regarded as an equivalent ground, which has a stronger shielding effect on electromagnetic wave signals. By setting a second connecting part, this electrical connection can connect the first component to a metal plate with a weaker shielding effect, thereby reducing the shielding effect of the first component on electromagnetic wave signals and weakening the water ripple phenomenon of electromagnetic wave signals.

[0076] Alternatively, in some embodiments, the second connection portion is disposed in the space between the second component and the metal plate, and two sides of the second connection portion are respectively connected to the second component and the metal plate.

[0077] As mentioned above, the second component can be a display screen on the camera side of the electronic device. When the radiator is arranged below the second component and above the metal plate, the second connecting part can be filled in the space between the second component and the metal plate to keep the metal plate and the second component at the same potential.

[0078] It should be understood that the position of the second connection portion can be specifically determined according to actual needs. In some embodiments, for example, even if the radiator is disposed between the second component and the metal plate, if there is space between the metal plate and the first component for arranging the second connection portion, the second connection portion can also be disposed between the first component and the metal plate.

[0079] The embodiment of the present application provides an electronic device, wherein the second connection portion is disposed in the space between the first component or the second component and the metal plate, so that the metal plate and the first component or the second component are connected to each other and have the same potential. In this way, the electromagnetic wave signal can be further directed to the frame of the electronic device, thereby reducing the water ripple phenomenon of the electromagnetic wave signal and improving the strength of the electromagnetic wave signal.

[0080] In some embodiments, continue to refer to Figure 7 , the radiator includes a feed point 207; wherein:

[0081] The feeding point 207 is arranged on the lower surface of the radiator and between the first connecting portion and the frame of the housing;

[0082] There is a first preset distance between the feeding point 207 and the metal plate.

[0083] In the embodiment of the present application, the feeding point 207 may be a signal access point of the radiator, and may be connected to other circuit boards or devices via leads or cables to direct signals to other devices or receive signals from other devices.

[0084] like Figure 7 As shown, one side of the radiator is fixed on the first connection part, the other end of the radiator is fixed on the frame of the electronic device, and the middle part is suspended and there is a distance between the metal plate. Therefore, the feeding point 207 can be set in the suspended space between the lower part of the radiator and the metal plate, and the first preset distance is maintained between the metal plate. In this way, the feeding point 207 can be ensured to work normally, and the radiator will not be short-circuited due to grounding.

[0085] The first preset distance may be actually determined according to the size of the feeding point 207 and the distance between the radiator and the metal plate.

[0086] The embodiment of the present application provides an electronic device, wherein the feeding point is arranged on the lower surface of the radiator and has a first preset distance from the metal plate, so that the suspended space between the radiator and the metal plate can be fully utilized and the normal operation of the feeding point is ensured.

[0087] In some embodiments, the second connection portion includes a first sub-connection portion and a second sub-connection portion; wherein:

[0088] The first sub-connection portion is disposed between one side of the metal plate and the first component, or between one side of the metal plate and the second component;

[0089] The second sub-connection portion is disposed between the other side of the metal plate and the first component, or is disposed between the other side of the metal plate and the second component.

[0090] In the embodiments of the present application, Fig. 9 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 5 , Fig.10 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application Figure 6 .like Fig. 9 , Fig.10 As shown, the first sub-connection part 2081 is arranged on one side of the metal plate and filled between the metal plate and the second component, and the second sub-connection part 2082 is arranged on the other side of the metal plate and filled between the metal plate and the second component.

[0091] As mentioned above, when the main screen of the electronic device is placed flat on the desktop with the main screen facing upward, the long side of the display screen is used as the Y axis, the short side is used as the X axis, and the direction perpendicular to the desktop on the electronic device is used as the Z axis. Fig. 9 is a schematic diagram of the electronic device 20 in the XOY plane, Fig.10 is a schematic diagram of the electronic device 20 in the YOZ plane. Fig.10 In order to avoid the first connection part from shielding the feeding point, the first connection part is not shown.

[0092] It can be seen that the first sub-connection portion 2081 and the second sub-connection portion 2082 are disposed on both sides of the metal plate 206 along the Y-axis direction, connecting the metal plate 206 and the second component 202 , so that the metal plate 206 and the second component 202 have the same potential.

[0093] It should be understood that the first sub-connection portion 2081 and the second sub-connection portion 2082 can also be arranged between the first component and the metal plate 206, or one of them is arranged between the first component and the metal plate 206, and the other is arranged between the second component and the metal plate 206. The specific arrangement method is determined according to the actual space in the electronic device 20. In addition, it should be understood that Fig. 9 , Fig.10 This is only an example of a setting method for the first sub-connection part 2081 and the second sub-connection part 2082. In actual application, the first sub-connection part 2081 and the second sub-connection part 2082 can be set at any position between the metal plate and the first component or the second component 202.

[0094] Fig.11 A radiation direction diagram provided in an embodiment of the present application Figure 2 .like Fig.11 As shown in (a), when the first sub-connection part and the second sub-connection part are not provided, the second component will directly suppress the electromagnetic wave signal radiated by the radiator, and the energy will be bound under the second component. The radiator can not be radiated very fully, causing the gain of the radiator to be obviously like water ripples. In this case, the energy of the radiator cannot be radiated at many angles, and only the energy at some angles is slightly stronger.

[0095] Therefore, the metal plate can be electrically connected to the metal plate on the back of the second component by respectively arranging the first sub-connection part and the second sub-connection part on both sides of the extension line of the first connection part. This connection method is equivalent to dividing a large metal screen (the second component) into a small metal plane by grounding. This small metal plane is not enough to block the electromagnetic wave signal. Fig.11 As shown in (b), after the first sub-connection part and the second sub-connection part are provided, the electromagnetic wave signal can be radiated, the water ripple phenomenon is weakened, and the design requirements of the radiator are met.

[0096] Fig.12 A radiation direction diagram provided in an embodiment of the present application Figure 3 . Fig.12 The figure shows the gain of the radiator at various angles, that is, the ability of the radiator to effectively concentrate energy to radiate or receive electromagnetic waves at various angles. The dotted line is the gain of the radiator at various angles after the first sub-connection part and the second sub-connection part are set in the electronic device; the solid line is the gain of the radiator at various angles when the first sub-connection part and the second sub-connection part are not set in the electronic device. It can be seen that after the first sub-connection part and the second sub-connection part are set, the electromagnetic wave signal is less likely to be shielded, and the gain of the radiator is improved at all angles, that is, in all directions, and the water ripple phenomenon of the gain is reduced.

[0097] The embodiment of the present application provides an electronic device, wherein the second connection part includes a first sub-connection part and a second sub-connection part, wherein the first sub-connection part and the second sub-connection part are arranged between the metal plate and the first component or the second component. In this way, the shielding of the electromagnetic wave signal by the first component or the second component can be reduced, the water ripple phenomenon of the gain can be reduced, and the performance of the radiator can be improved.

[0098] In another embodiment of the present application, see Figure 7 and Fig. 9The radiator 203 is arranged parallel to the first component and / or the second component 202, and the first connecting portion 204 has a first side and a second side arranged opposite to each other, wherein the first side is connected to the target side of the radiator 203 away from the target side of the shell, and the second side is grounded.

[0099] In the embodiments of the present application, Figure 7 and Fig. 9 As shown, for example, the first connection part 204 may be a strip structure parallel to the frame, wherein the first side of the first connection part 204 may be a side close to the second component along the Z-axis direction, parallel to the frame, and connected to the target side of the radiator 203 away from the target side; the second side of the first connection part 204 may be a side away from the second component along the Z-axis direction, and the second side is connected to the metal plate, which is equivalent to grounding. In this way, the target sides of the radiator 203 can be grounded to prevent the electromagnetic wave signal from being transmitted in the direction of the first connection part 204.

[0100] In the embodiments of the present application, Fig.13 This is a schematic diagram of an electric field of an electronic device provided in an embodiment of the present application. Fig.13 As shown in (a), the radiator 203 is arranged at the lower right corner of the first body 2021 in the second component of the electronic device for explanation. It should be understood that the radiator 203 can be arranged in the electronic device at any position under the display screen near the frame. Fig.13 (b) and Fig.13 It corresponds to (a) in the figure, which is used to describe the electric field (E-field) when electronic equipment and radiators are working normally. The lighter the color, the stronger the radiation intensity. Fig.13 In the lower right corner of (b), the electric field strength is relatively strong around the area corresponding to the radiator, indicating that based on the structure provided in the embodiment of the present application, the electromagnetic wave signal of the radiator can be concentrated on the frame of the electronic device and radiated outside the electronic device with relatively strong intensity.

[0101] The embodiment of the present application provides an electronic device, wherein the first side of the first connection portion is connected to the target side of the radiator away from the target side, and the second side of the first connection portion is grounded. In this way, the target side of the radiator can be grounded, so that the electromagnetic wave signal is prevented from being transmitted in the direction of the first connection portion, and the intensity of the electromagnetic wave signal radiated by the radiator to the target side is enhanced.

[0102] In some embodiments, see Fig. 9 , the radiator 203 also includes a first side and a second side; wherein: the target side is arranged parallel to the first connecting portion 204, the target side is respectively connected to the first side and the second side, and the target side also has an angle with the first side and the second side respectively.

[0103] In the embodiments of the present application, Fig. 9As shown, exemplarily, the first side of the radiator 203 can be the radiator 203 along the Y-axis direction, with one end connected to the first connector and the other end close to one side of the frame of the electronic device, and the second side of the radiator 203 can be the radiator 203 along the Y-axis direction, with one end connected to the first connector and the other end close to the other side of the frame of the electronic device.

[0104] It should be understood that Fig. 9 As shown, the first side and the second side of the electronic device are perpendicular to the frame of the electronic device and the first connecting portion 204, which is one embodiment, and the angles between the first side, the second side and the target side are all 90 degrees. In some embodiments, the radiator 203 may be an irregular sheet structure, so that the first side and the second side of the radiator 203 may have an angle with the target side, and the angle is determined according to the actual shape of the radiator 203.

[0105] The embodiment of the present application provides an electronic device, wherein the radiator includes a first side and a second side connected to a target side, and the first side and the second side both have an angle with the target side. In this way, even if the shape of the radiator is irregular, the electromagnetic wave signal can still be radiated outward based on the above structure.

[0106] In yet another embodiment of the present application, a radiator is provided, wherein:

[0107] The radiator is used to radiate electromagnetic wave signals;

[0108] The radiator is arranged in an accommodating space formed by a portion of the electronic device where the screen where the first component is located and the plane where the second component is located are parallel, and one side of the radiator is close to the side of the first component and the second component, and the side of the radiator away from the target side is grounded through a first connecting part, wherein the target side is the side of the first component and the second component close to the shell, and the first component and the second component are components that affect the radiator to radiate electromagnetic wave signals.

[0109] In some embodiments, the radiator comprises a feed point; wherein:

[0110] The feeding point is arranged on the lower surface of the radiator and between the first connecting portion and the frame of the shell;

[0111] There is a first preset distance between the feeding point and the metal plate.

[0112] In some embodiments, the radiator is arranged parallel to the first component and / or the second component, and the first connecting portion has a first side and a second side arranged opposite to each other, wherein the first side is connected to the target side of the radiator away from the target side of the shell, and the second side is grounded.

[0113] In some embodiments, the radiator further comprises a first side and a second side; wherein:

[0114] The target side is arranged in parallel with the first connecting portion, the target side is connected to the first side and the second side respectively, and the target side also has an angle with the first side and the second side respectively.

[0115] It should be understood that since the radiator and any of the electronic devices provided above belong to the same inventive concept, the structure of the radiator can refer to the above Figure 7 , Fig. 9 and Fig.10 It should be understood that the radiator may also include any other possible components or modules to achieve the functions and effects that the above electronic device can achieve. Similarly, the electronic device may also include any other possible components to enable the radiator to achieve corresponding functions. The embodiments of the present application will not be repeated here.

[0116] In the embodiment of the present application, the structure of the radiator cooperates with other structures in the aforementioned electronic device to achieve corresponding functions. The structure, implementation principle and technical effect of the radiator in the embodiment of the present application and the electronic device in which the radiator is located are similar to the structure, implementation principle and technical effect of the radiator in the aforementioned electronic device, and will not be repeated here.

[0117] In the embodiment of the present application, under the premise of maintaining the design of the folding machine sub-screen as a full-screen and not changing the design and performance of the sub-screen body, the radiator, such as the UWB antenna, is designed to be below the edge of the sub-screen in the Z direction. Through the reasonable design of the UWB antenna itself and the grounding design between the sub-screen and the ground plane of the UWB antenna, the UWB antenna under the folding machine sub-screen can be realized, and the same antenna radiation performance as that without the sub-screen can be maintained. The structure of the radiator refers to the aforementioned Figure 7 , Fig. 9 and Fig.10 .

[0118] In the embodiment of the present application, by adding a first connection part (Ground-wall) grounding design in the electronic device, the radiation direction of the radiator can be effectively turned to the outside of the electronic device. When applied to the under-screen UWB antenna, the radiation direction can be effectively directed to the edge of the secondary screen of the electronic device, which is conducive to the radiation of electromagnetic wave energy.

[0119] In the embodiment of the present application, considering the influence of the metal on the back of the secondary screen on the UWB antenna, the untreated secondary screen has a great influence on the UWB antenna, which will directly suppress the radiation of the UWB antenna, bind the energy under the secondary screen, and cause obvious Gain ripples. By grounding the UWB antenna Ground-wall extension line on both sides through the second connection part (GND to panel), the UWB antenna Ground plane and the metal plate on the back of the secondary screen are electrically connected, and the radiation direction can be further directed to the edge of the secondary screen, thereby improving the UWB antenna Gain value in all directions, reducing the Gain water ripple phenomenon, and meeting the UWB antenna design requirements.

[0120] The embodiment of the present application provides a radiator, which makes the radiation characteristics of the radiator equivalent to those when there is no display screen blocking it, without changing the design requirement of the secondary screen as a full screen, without changing the design and display performance of the secondary screen body, and without increasing the cost of the display screen.
