Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an electronic device and an antenna assembly. Background Art

[0002] Electronic devices have non-contact functions such as air gesture interaction and non-contact physiological sign detection, which can improve the convenience of users' interaction with electronic devices.

[0003] The contactless function can be implemented by using electromagnetic waves. Users usually operate the electronic device at the front side of the electronic device. Therefore, an antenna needs to be arranged at the front side of the electronic device to achieve electromagnetic wave coverage of the front side of the electronic device.

[0004] For electronic devices with full screens and ultra-narrow bezels, it is relatively difficult to set an antenna on the front side of the electronic device due to the size limitations of the full screens and ultra-narrow bezels. Summary of the invention

[0005] The present application provides an electronic device and an antenna assembly, which realize electromagnetic wave coverage on the front side of the electronic device.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] In a first aspect, the present application provides an electronic device, comprising: a display module, a first camera module, a device module, an elevated circuit board, and an antenna; wherein the display module comprises a light-transmitting cover plate and a display screen that are fixedly connected, and the display screen has an opening opposite to the first camera module and the device module; the first camera module and the device module are distributed along a first direction, the first camera module, the display screen and the light-transmitting cover plate are distributed along a second direction, the device module, the display screen and the light-transmitting cover plate are distributed along the second direction, and there is an angle between the second direction and the first direction; the first camera module has a first end facing away from the opening and a second end facing the opening, the length of the first end of the first camera module in the first direction is greater than the length of the second end of the first camera module in the first direction; there is a gap between the first camera module and the device module, the elevated circuit board is located in the gap, and the elevated circuit board is close to the display screen; the antenna is arranged on the elevated circuit board.

[0008] It can be seen from the above content that: the length of the first end of the first camera module in the first direction is greater than the length of the second end of the first camera module in the first direction, then the gap between the first camera module and the device module is partially larger and partially smaller; the elevated circuit board is located in the gap, and the elevated circuit board is close to the display screen, so that the elevated circuit board is set at the place where the gap is larger; the antenna is set on the elevated circuit board, so that the antenna is set at the place where the gap is larger, and the antenna is close to the display module, and the electromagnetic waves emitted by the antenna can pass through the display module and reach the front side of the electronic device, so that the antenna achieves electromagnetic wave coverage on the front side of the electronic device.

[0009] The antenna is located in the gap between the first camera module and the device module, which avoids the antenna affecting the transmittance of the opening, improves the transmittance of the opening, avoids the antenna affecting the light reaching the first camera module and the device module, and reduces the impact of the antenna on the first camera module and the device module; the antenna is set on the elevated circuit board, the antenna does not need to be transparently processed, and the processing cost of the antenna is reduced.

[0010] The elevated circuit board and the antenna are located at the larger end of the gap between the first camera module and the device module. In this way, the antenna is set at the larger gap, and the existing space inside the electronic device is fully utilized to set the antenna. There is no need to change the original structure inside the electronic device. For example, there is no need to increase the gap between the first camera module and the device module, and there is no need to increase the opening, which can avoid increasing the opening, thereby increasing the effective display area of ​​the display module and improving the aesthetics of the electronic device.

[0011] Since the elevated circuit board is elevated, the antenna is also elevated. Compared with the antenna that is not elevated, the elevated antenna reduces the degree of shielding of the antenna's field of view (wave width) by the shielding layer around the opening, reduces the degree of narrowing of the antenna's field of view, makes the antenna's field of view larger, and improves the antenna's performance; it also reduces the amount of unnecessary reflections and increases the isolation between the various parts of the antenna, thereby reducing the influence of the shielding layer around the opening on the antenna's radiation pattern and improving the antenna's performance.

[0012] In a possible implementation, the electronic device further includes a support member, the support member is located in the gap, and the elevated circuit board is fixed to one end of the support member close to the display screen.

[0076] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context.

[0077] References to "some embodiments" and the like described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way. The terms "include", "comprises", "has" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in another way.

[0078] In the description of the embodiments of the present application, words such as "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0079] Electronic devices such as mobile phones and tablets have non-contact functions such as air gesture interaction and non-contact physiological sign detection, which can improve the convenience of users' interaction with electronic devices.

[0080] Non-contact functions can be realized by using electromagnetic waves. For example, the air gesture interaction technology recognizes the user's hand movements by emitting electromagnetic waves and receiving their reflected signals; the non-contact physiological sign detection senses the user's physiological signs by emitting electromagnetic waves and receiving their reflected signals.

[0081] Users usually operate electronic devices on the front side of the electronic device, so it is necessary to set an antenna on the front side of the electronic device to achieve electromagnetic wave coverage on the front side of the electronic device. The front side of the electronic device can be understood as: the front side of the screen of the electronic device, and can also be understood as: the side where the light incident surface of the front camera module of the electronic device faces.

[0082] For electronic devices with full screens and ultra-narrow bezels, it is relatively difficult to set an antenna on the front side of the electronic device due to the size limitations of the full screens and ultra-narrow bezels.

[0083] Take mobile phones as an example. Figure 1-Figure 3 A method of setting an antenna on the screen side of a mobile phone in the related art is demonstrated.

[0084] Figure 1 is a schematic diagram of the structure of the mobile phone 100, Figure 2 is a schematic diagram of the structure of the display module 2 in the mobile phone, Figure 3 It is a schematic diagram of the structure of the display screen 202 in the mobile phone. It should be noted that: Figure 2 Part of the display module 2 is shown.

[0085] like Figure 1-Figure 3 As shown, the mobile phone 100 is a full-screen mobile phone, and the mobile phone 100 includes a housing 1, a display module 2, a camera module 3 and an antenna 4.

[0086] The housing 1 is used to protect the internal electronic components of the mobile phone 100. The housing 1 includes a rear cover 101 and a middle frame 102 which are fixedly connected. The middle frame 102 is closer to the display module 2 than the rear cover 101.

[0087] The display module 2 is used to display images, videos, etc. The display module 2 includes a stacked transparent cover plate 201 and a display screen 202. The transparent cover plate 201, the back cover 101 and the middle frame 102 form an internal accommodation space of the mobile phone 100. The internal accommodation space accommodates the display screen 202.

[0088] The camera module 3 is used to take photos / videos, and the camera module 3 is fixed in the internal accommodating cavity of the mobile phone 100. The camera module 3 is used as a front camera module, and the light incident surface of the camera module 3 faces the display module 2. The display screen 202 has an opening 2021 opposite to the camera module 3. The opening 2021 is circular, and the axis of the opening 2021 is collinear with the axis of the camera module 3.

[0089] The antenna 4 is arranged in the opening 2021, and the antenna 4 is located between the camera module 3 and the display module 2. The antenna 4 can achieve electromagnetic wave coverage on the front side of the mobile phone 100. However, the antenna 4 needs to be transparent, resulting in a high processing cost of the antenna 4; although the antenna 4 has completed the transparent processing, it will still reduce the light transmittance of the opening 2021, affecting the imaging effect, and ultimately affecting the performance of the camera module 3.

[0090] From the above content, it can be seen that the technical solution of setting an antenna on the screen side in the related technology, although it realizes electromagnetic wave coverage on the front side of the electronic device, it will cause other problems (the processing cost of the transparently treated antenna 4 is high, and the transmittance of the opening 2021 is low).

[0091] In view of this, an embodiment of the present application provides a technical solution for setting an antenna on the screen side, which can achieve electromagnetic wave coverage on the front side of the electronic device without affecting the performance of the electronic device due to the introduction of other problems (the processing cost of the transparent antenna is high and the transmittance of the opening is low).

[0092] In the embodiments of the present application, the electronic device includes: a mobile phone, a tablet computer, a personal computer, a laptop computer, a wearable device, a vehicle-mounted device, AR (augmented reality) / VR (virtual reality), an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA) and the like.

[0093] The following takes the mobile phone as an example. Figure 4-Figure 7 The structure of an electronic device is described. Figure 4 This is a schematic diagram of the structure of the mobile phone 100 provided in an embodiment of the present application. Figure 5 for Figure 4 AA section view of the partial structure diagram, Figure 6 is a schematic diagram of the distribution of antenna 4 in the first direction and the second direction, Figure 7 It is a schematic diagram of the distribution of antenna 4 in the third direction and the second direction.

[0094] In the embodiment of the present application, the mobile phone 100 is a full-screen mobile phone. In actual situations, the mobile phone 100 can also be a narrow-frame mobile phone or a wide-frame mobile phone, which is not limited in the embodiment of the present application.

[0095] like Figure 4-Figure 7 As shown, the mobile phone 100 includes: a housing 1, a display module 2, a camera module 3, a mainboard 6, a support member 8, an elevated circuit board 7, an antenna 4 and a chip 9.

[0096] For the convenience of the following description, a coordinate system is established. The distribution direction of the two camera modules 3 is defined as the first direction, the height direction (axial direction) of the camera module 3 is defined as the second direction, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction and the second direction.

[0097] It should be noted that the width direction of the mobile phone 100 can be understood as the first direction, the thickness direction of the mobile phone 100 can be understood as the second direction, and the length direction of the mobile phone 100 can be understood as the third direction. The "vertical" involved in this application is "substantially vertical" in actual operation. In actual situations, there can be an angle between the first direction and the second direction, there can be an angle between the second direction and the third direction, and there can be an angle between the third direction and the first direction, and the angle is not limited to 90°.

[0098] like Figure 4 As shown, the housing 1 is used to protect the internal electronic components of the mobile phone 100. The housing 1 includes a back cover 101 and a middle frame 102 that are fixedly connected, and the back cover 101 and the middle frame 102 are distributed along the second direction.

[0099] The housing 1 and the display module 2 are distributed along the second direction, which can be understood as: the back cover 101, the middle frame 102 and the display module 2 are distributed along the second direction.

[0100] like Figure 5 As shown, the display module 2 is used to display images, videos, etc. The display module 2 includes a light-transmitting cover plate 201 and a display screen 202 which are stacked and arranged, and the light-transmitting cover plate 201 and the display screen 202 are distributed along the second direction.

[0101] The light-transmitting cover plate 201 is mainly used to protect and prevent dust from the display screen 202. The material of the light-transmitting cover plate 201 includes but is not limited to glass. The display screen 202 can be a flexible display screen or a rigid display screen.

[0102] The transparent cover plate 201, the display screen 202 and the back cover 101 are distributed along the second direction, the middle frame 102 is located between the back cover 101 and the transparent cover plate 201, and the transparent cover plate 201, the back cover 101 and the middle frame 102 form an internal accommodation space of the mobile phone 100. The internal accommodation space accommodates the display screen 202.

[0103] The display screen 202 has a shielding layer 2022 on one side away from the transparent cover plate 201. The shielding layer 2022 is a conductive layer and is connected to the ground terminal (not shown) of the display screen 202. In this way, the shielding layer 2022 can provide electromagnetic shielding, signal grounding, heat dissipation and other functions.

[0104] The display screen 202 is provided with an opening 2021 opposite to the camera module 3 to ensure that light reaches the camera module 3 after passing through the light-transmitting cover plate 201. It is understandable that the display screen 202 has no shielding layer 2022 at the opening 2021.

[0105] The camera module 3 is used to take photos / videos, and the camera module 3 is fixed in the internal accommodation cavity of the mobile phone 100. Exemplarily, the camera module 3 is fixed to the middle frame 102 by a bracket. The camera module 3 can be used as a front camera module. There are two camera modules 3, and the light incident surfaces 301 of the two camera modules 3 face the display module 2, and the two camera modules 3 are opposite to the opening 2021.

[0106] It should be noted that the two camera modules 3 can be respectively referred to as a first camera module and a second camera module. The second camera module can also be replaced by other device modules such as a light sensor, a proximity light module, and an ultrasonic module.

[0107] The opening 2021 may be a strip-shaped hole, for example, the opening 2021 is a waist-shaped hole, and such an opening 2021 corresponds to two camera modules 3. It should be noted that the length direction of the opening 2021 is also the first direction, the axial direction of the opening 2021 is also the second direction, and the width direction of the opening 2021 is the third direction.

[0108] In actual situations, the opening 2021 may also be in other shapes and is not limited to a strip shape.

[0109] The camera module 3 may be an infrared camera, a depth sensing lens or other types, and the embodiment of the present application does not limit the type of the camera module 3. The two camera modules 3 may be of different or the same type.

[0110] The number of camera modules 3 may be more than three, and one opening 2021 may correspond to more than three camera modules 3.

[0111] The length of the first end of the camera module 3 away from the display module 2 in the first direction is the first length L1, and the length of the second end of the camera module 3 close to the display module 2 in the first direction is the second length L2, and the first length L1 is greater than the second length L2. It can be understood that the second end of the camera module 3 faces the opening 2021, and the first end of the camera module 3 faces away from the opening 2021.

[0112] In the first direction, there is a gap 01 between the two camera modules 3. Because the first length L1 is greater than the second length L2, the gap 01 is wider at the end close to the display module 2 in the first direction, and is narrower at the end far from the display module 2 in the first direction.

[0113] It should be noted that, when a camera module 3 is a device module, the gap 01 is the gap between the first camera module and the device module. It is sufficient to ensure that the width of the gap 01 in the first direction is larger at the end close to the display module 2 and smaller at the end far from the display module 2.

[0114] The support member 8 is located between the two camera modules 3. In some embodiments, the support member 8 is fixed to the mainboard 6, which facilitates the arrangement of the support member 8.

[0115] In some other embodiments, the support member 8 is fixed to the back cover 101 , the support member 8 is fixed to the middle frame 102 , or the support member 8 is fixed to other positions of the internal accommodating cavity of the mobile phone 100 .

[0116] In the second direction, the support member 8 has a first end and a second end. The first end of the support member 8 is away from the display screen 202, and the second end of the support member 8 is close to the display screen 202. It can be understood that: in the second direction, the support member 8 has a set height to ensure that the circuit board 7 is supported and raised.

[0117] There may be one support member 8 or more than two support members 8 , and the embodiment of the present application does not limit the number of support members 8 .

[0118] The support member 8 can be a support column or a support plate, etc., which can be selected according to actual needs. In order to improve the support stability, the support member 8 can be selected as a support column.

[0119] The elevated circuit board 7 is used to set the antenna 4, etc. The elevated circuit board 7 is set at the second end of the support member 8, so that the elevated circuit board 7 is closer to the display screen 202 than the first end of the camera module 3, which can be understood as: the elevated circuit board 7 is located at the larger end of the gap 01 in the second direction.

[0120] The elevated circuit board 7 and the support member 8 may be an integrated structure or a split structure. Exemplarily, the elevated circuit board 7 and the support member 8 are a split structure, and the support member 8 and the elevated circuit board 7 may be welded or bonded.

[0121] The support member 8 is used to elevate the elevated circuit board 7 . Since the support member 8 is located in the gap 01 , the space in the gap 01 is fully utilized to elevate the elevated circuit board 7 , thereby improving the compactness of the internal structure of the mobile phone 100 .

[0122] In actual situations, the elevated circuit board 7 may be elevated in other ways, for example, the elevated circuit board 7 is directly fixedly connected to the camera module 3 or other existing components inside the mobile phone 100 .

[0123] In the second direction, the elevated circuit board 7 and the second end of the camera module 3 are arranged flush with each other, or there is a height difference between the elevated circuit board 7 and the second end of the camera module 3. In order to make the antenna 4 on the elevated circuit board 7 as close to the display module 2 as possible, the elevated circuit board 7 and the second end of the camera module 3 can be arranged flush with each other, or the elevated circuit board 7 is closer to the display module 2 than the second end of the camera module 3.

[0124] The portion of the elevated circuit board 7 is opposite to the opening 2021, and the user can easily see the elevated circuit board 7 through the transparent cover plate 201, which affects the aesthetics of the mobile phone 100. Based on this, the board surface of the elevated circuit board 7 close to the display module 2 can be selected as a black surface. Exemplarily, the elevated circuit board 7 is sprayed black, which can be understood as: the board surface of the elevated circuit board 7 close to the display module 2 has a sprayed black treatment layer (not shown in the figure), and the sprayed black treatment layer covers the board surface of the elevated circuit board 7 close to the display module 2. In this way, the elevated circuit board 7 is not easy to see on the front side of the mobile phone 100, which improves the aesthetics of the mobile phone 100.

[0125] The elevated circuit board 7 may be a PCB (Printed Circuit Board) or other types, which is not limited in the embodiment of the present application.

[0126] Antenna 4 is used to implement contactless functions of mobile phone 100, such as air gesture interaction, contactless physiological sign detection, etc. According to the purpose of antenna 4, antenna 4 can be a communication antenna (such as a high-frequency communication antenna) or a radar antenna; according to the working wavelength of antenna 4, antenna 4 can be a millimeter wave antenna, THz (terahertz) antenna, centimeter wave antenna or antenna of other frequencies.

[0127] Figure 6-Figure 8 The specific structure of the antenna 4 is shown. Figure 8 for Figure 4 The enlarged schematic diagram of part B in the figure is as follows: Figure 8 The distribution of the antenna 4 in the first direction and the third direction is shown. It should be noted that: Figure 8 The display module 2 is hidden in order to display components such as the antenna 4 and the elevated circuit board 7.

[0128] like Figure 6-Figure 8 As shown, the antenna 4 includes an antenna transmitting unit 401 and an antenna receiving unit 402. The antenna transmitting unit 401 is used to transmit electromagnetic waves, and the antenna receiving unit 402 is used to receive electromagnetic waves. The antenna transmitting unit 401 and the antenna receiving unit 402 are both arranged on the elevated circuit board 7.

[0129] For example, Figure 8In the figure, the antenna transmitting unit 401 includes a first antenna 4011 and a second antenna 4012, both of which are used to transmit electromagnetic waves. The antenna receiving unit 402 includes a third antenna (not marked in the figure), which is used to receive electromagnetic waves. Based on this, it can be understood that the antenna 4 includes three antenna parts. In actual situations, the antenna 4 can also be selected to include two antenna parts or more than four antenna parts.

[0130] The antenna 4 needs to be opposite to the opening 2021 to ensure that the antenna 4 achieves electromagnetic wave coverage on the front side of the mobile phone 100. In some embodiments, the antenna transmitting unit 401 and the antenna receiving unit 402 are distributed along the first direction. In this way, the distribution direction of the antenna transmitting unit 401 and the antenna receiving unit 402 is the same as the length direction of the opening 2021, so that the antenna transmitting unit 401 and the antenna receiving unit 402 are both opposite to the opening 2021, so that the antenna 4 achieves electromagnetic wave coverage on the front side of the mobile phone 100.

[0131] In the first direction, the positions of the antenna transmitting unit 401 and the antenna receiving unit 402 can be interchanged, and are not limited to Figure 6 and Figure 8 The first antenna 4011 and the second antenna 4012 are arranged in a third direction. In the third direction, the positions of the first antenna 4011 and the second antenna 4012 can be interchanged, and are not limited to Figure 7 and Figure 8 Arrangement shown.

[0132] In some other embodiments, when the width of the opening 2021 is relatively large, the antenna transmitting unit 401 and the antenna receiving unit 402 may be distributed along a third direction, and the first antenna 4011 and the second antenna 4012 may be distributed along the first direction.

[0133] The antenna 4 can be a PCB printed antenna, or other types of antennas welded or connected to the elevated circuit board 7. The manufacturing method of the antenna 4 can be a traditional antenna processing and manufacturing method, which reduces the processing cost of the antenna 4 compared to the transparently processed antenna (transparent antenna).

[0134] The antenna 4 is arranged on the elevated circuit board 7. Exemplarily, the antenna 4 is located on the side of the elevated circuit board 7 close to the display module 2 (display screen 202), which can be understood as: the antenna transmitting unit 401 and the antenna receiving unit 402 are both arranged on the side of the elevated circuit board 7 close to the display module 2; or, the antenna 4 is located on the side of the elevated circuit board 7 away from the display module 2 (display screen 202), which can be understood as: the antenna transmitting unit 401 and the antenna receiving unit 402 are both arranged on the side of the elevated circuit board 7 away from the display module 2.

[0135] Since the antenna 4 is arranged on the elevated circuit board 7, the antenna 4 is arranged close to the display module 2. The electromagnetic waves emitted by the antenna 4 can pass through the display module 2 and reach the front side of the mobile phone 100, thereby achieving electromagnetic wave coverage on the front side of the mobile phone 100.

[0136] It should be noted that the front side of the mobile phone 100 can be understood as: the side where the light incident surface of the camera module 3 faces, and the front side of the mobile phone 100 can also be understood as: the side where the display module 2 is away from the housing 1. Since the elevated circuit board 7 is elevated, the antenna 4 is also elevated, so that the antenna 4 is located at one end of the gap 01 close to the display module 2.

[0137] As described above, the display screen 202 in the display module 2 has a shielding layer 2022 on the side away from the transparent cover plate 201 . Therefore, the antenna 4 and the display screen 202 are not in contact, which can be understood as: there is a gap between the antenna 4 and the display screen 202 .

[0138] As mentioned above, the elevated circuit board 7 is located in the gap 01 between the two camera modules 3, and the antenna 4 is also located in the gap 01 between the two camera modules 3, which avoids the antenna 4 affecting the transmittance of the opening 2021, improves the transmittance of the opening 2021, avoids the antenna 4 affecting the light reaching the camera module 3, and reduces the impact of the antenna 4 on the camera module 3; as mentioned above, the antenna 4 is set on the elevated circuit board 7, and the antenna 4 can be a PCB printed antenna, or other types of antennas welded or connected to the elevated circuit board 7. The antenna 4 does not need to be transparently processed, which reduces the processing cost of the antenna 4.

[0139] The support member 8 elevates the elevated circuit board 7 so that the elevated circuit board 7 and the antenna 4 are located at the end with a larger gap 01. In this way, the larger gap 01 between the two camera modules 3 is utilized to set the antenna 4, and the existing space inside the mobile phone 100 is fully utilized to set the antenna 4. There is no need to change the original structure inside the mobile phone 100. For example, there is no need to increase the gap 01 between the two camera modules 3, and there is no need to increase the opening 2021. The increase in the opening 2021 can be avoided, thereby increasing the effective display area of ​​the display module 2 and improving the aesthetics of the mobile phone 100.

[0140] The first antenna 4011, the second antenna 4012 and the third antenna (antenna receiving unit 402) mentioned above all have a field of view angle. The field of view angle of the antenna is explained by taking the first antenna 4011 as an example. Figure 6 and Figure 7The angle of the field of view of the first antenna 4011 in the first direction is the horizontal field of view angle θ1, and the angle of the field of view of the first antenna 4011 in the third direction is the vertical field of view angle θ2. The closer the first antenna 4011 is to the display module 2, the less the shielding layer 2022 around the opening 2021 blocks the field of view angles of the antenna 4 (the horizontal field of view angle θ1 and the vertical field of view angle θ2). Figure 6 and Figure 7 In the figure, the double-dotted lines represent the emission and transmission of the signal. The closer the first antenna 4011 is to the display module 2, the smaller the reflection of the signal by the shielding layer 2022 around the opening 2021, and the smaller the angle of the signal on the first antenna 4011 will be reflected to the second antenna 4012 and the third antenna (antenna receiving unit 402). Therefore, the isolation between the first antenna 4011 and the second antenna 4012 is greater, and the isolation between the first antenna 4011 and the third antenna is greater.

[0141] From the above content, it can be seen that the elevated antenna 4, compared with the antenna 4 not elevated, reduces the degree of shielding of the field of view (wave width) of the antenna 4 by the shielding layer 2022 around the opening 2021, reduces the degree of reduction of the field of view of the antenna 4, makes the field of view of the antenna 4 larger, and improves the performance of the antenna 4; it also reduces the amount of unnecessary reflection, increases the isolation between the various parts of the antenna 4, thereby reducing the influence of the shielding layer 2022 around the opening 2021 on the antenna radiation pattern, and improves the performance of the antenna 4. Continue to refer to Figure 6 and Figure 7 , the chip 9 is electrically connected to the antenna 4 to achieve interconnection between the chip 9 and the antenna 4. Exemplarily, the chip 9 and the antenna 4 are interconnected through an interconnection line 19, and the interconnection line 19 can be a microstrip line, CPW (Coplanar waveguide) or SIW (Substrate integrated waveguide) or the like.

[0142] In some embodiments, the chip 9 is set on the elevated circuit board 7, so that the chip 9 and the antenna 4 are integrated into the elevated circuit board 7. It can be understood that: the chip 9 and the antenna 4 are integrated on the same circuit board, shortening the distance between the chip 9 and the antenna 4 and reducing the interconnection loss from the antenna 4 to the chip 9.

[0143] Exemplarily, the chip 9 and the antenna 4 are respectively located on both sides of the elevated circuit board 7, which can be understood as: the antenna 4 is located on the side of the elevated circuit board 7 close to the display module 2, and the chip 9 is located on the side of the elevated circuit board 7 away from the display module 2; or, the chip 9 and the antenna 4 are located on the same side of the elevated circuit board 7, which can be understood as: the chip 9 and the antenna 4 are both located on the side of the elevated circuit board 7 close to the display module 2.

[0144] The chip 9 is electrically connected to the mainboard 6 (communication connection) to ensure signal transmission between the mainboard 6 and the chip 9. Since the chip 9 is arranged on the elevated circuit board 7, the chip 9 can be connected to the mainboard 6 by signal through the elevated circuit board 7. Exemplarily, the chip 9 is electrically connected to the elevated circuit board 7, and the elevated circuit board 7 is electrically connected to the mainboard 6 to realize the signal connection between the mainboard 6 and the chip 9.

[0145] In order to achieve electrical connection between the elevated circuit board 7 and the main board 6, the support member 8 may be selected to have a signal transmission part, so that the elevated circuit board 7 and the main board 6 are connected by the signal transmission part of the support member 8 to achieve signal transmission.

[0146] In actual situations, the elevated circuit board 7 and the main board 6 can also be electrically connected in other ways. For example, Fig. 9 Another way of electrically connecting the elevated circuit board 7 and the main board 6 is shown. It should be noted that Fig. 9 The display module 2 is hidden in the figure to display components such as the antenna 4 and the elevated circuit board 7. Fig. 9 As shown, the elevated circuit board 7 can be electrically connected to the main board 6 through an FPC (Flexible Printed Circuit) 17 and a BTB connector (Board-to-board Connectors) 18. Exemplarily, one end of the FPC 17 is electrically connected to the elevated circuit board 7, the other end of the FPC 17 is electrically connected to one end of the BTB connector 18, and the other end of the BTB connector 18 is electrically connected to the main board 6.

[0147] In some other embodiments, the chip 9 can be set on the mainboard 6 of the mobile phone 100, so that the chip 9 can be directly electrically connected to the mainboard 6 to realize signal transmission, and the chip 9 no longer needs to be electrically connected to the mainboard 6 through the elevated circuit board 7.

[0148] In the embodiment of the present application, the main board 6 is set to be grounded, and the elevated circuit board 7 also needs to be grounded. In order to facilitate the grounding of the elevated circuit board 7, the elevated circuit board 7 and the main board 6 can be grounded. Exemplarily, the elevated circuit board 7 and the main board 6 are grounded and connected through the grounding part of the support member 8.

[0149] It should be noted that, when the elevated circuit board 7 and the main board 6 are electrically connected via the support member 8 to achieve signal transmission and the elevated circuit board 7 and the main board 6 are grounded via the support member 8, the support member 8 has a signal transmission part and a grounding part, and the elevated circuit board 7 and the main board 6 are electrically connected via the signal transmission part of the support member 8 to achieve signal transmission and the elevated circuit board 7 and the main board 6 are grounded via the grounding part of the support member 8.

[0150] Due to the limited size of the elevated circuit board 7, the distance between the antenna transmitting unit 401 and the antenna receiving unit 402 of the antenna 4 is small, and the antenna transmitting unit 401 and the antenna receiving unit 402 are more likely to affect each other, thereby reducing the performance of the antenna 4. In order to improve the performance of the antenna 4, the antenna transmitting unit 401 and the antenna receiving unit 402 need to be isolated.

[0151] Combine the following Figure 8-Figure 10 , and combined with the situation where there is a TOF component 10 between the two camera modules 3, the specific structure of isolating the antenna transmitting unit 401 and the antenna receiving unit 402 is explained.

[0152] Combine first Figure 8 and Fig. 9 , a specific structure for isolating the antenna transmitting unit 401 and the antenna receiving unit 402 when the chip 9 is located on the side of the elevated circuit board 7 away from the display module 2 (the antenna 4 is located on the side of the elevated circuit board 7 close to the display module 2).

[0153] like Figure 8 and Fig. 9 As shown, one of the two camera modules 3 is a depth sensing lens or an infrared lens, and a TOF (Time of flight) component 10 is disposed between the two camera modules 3. The TOF component 10 cooperates with the depth sensing lens to realize functions such as 3D face recognition. It should be noted that the TOF component 10 can also be called a structured light emitting device, and the TOF component 10 is located in the gap 01.

[0154] The TOF component 10 is located on a side of the elevated circuit board 7 close to the display module 2, which can be understood as: the TOF component 10 protrudes from the elevated circuit board 7. The TOF component 10 is arranged on the elevated circuit board 7, or the TOF component 10 is arranged on the main board 6, and the TOF component 10 passes through the elevated circuit board 7.

[0155] The TOF component 10 is located between the antenna transmitting unit 401 and the antenna receiving unit 402, and the TOF component 10 has a conductive shell, which can be a metal shell or a shell made of other conductive materials.

[0156] A first flexible conductive member 11 and a second flexible conductive member 12 are disposed on the elevated circuit board 7. It can be understood that the first flexible conductive member 11 and the second flexible conductive member 12 both protrude from the elevated circuit board 7.

[0157] The first flexible conductive member 11 may be conductive foam, aluminum or conductive rubber, etc., and the second flexible conductive member 12 may be conductive foam, aluminum or conductive rubber, etc. Exemplarily, both the first flexible conductive member 11 and the second flexible conductive member 12 are conductive foam.

[0158] In the third direction, the first flexible conductive member 11 , the conductive housing of the TOF assembly 10 , and the second flexible conductive member 12 are grounded and connected in sequence, and separate the antenna transmitting unit 401 and the antenna receiving unit 402 .

[0159] The first flexible conductive member 11 and the second flexible conductive member 12 are both in contact with the shielding layer 2022 of the display module 2 and are grounded. Since the first flexible conductive member 11 and the second flexible conductive member 12 are flexible, the first flexible conductive member 11 and the second flexible conductive member 12 are both in flexible contact with the shielding layer 2022, thereby reducing the impact on the shielding layer 2022.

[0160] Since the shielding layer 2022 is grounded, the first flexible conductive member 11, the second flexible conductive member 12 and the conductive shell of the TOF component 10 are all grounded, so that the first flexible conductive member 11, the second flexible conductive member 12 and the conductive shell of the TOF component 10 isolate the antenna transmitting unit 401 and the antenna receiving unit 402, reducing the probability of mutual interference between the antenna transmitting unit 401 and the antenna receiving unit 402; the shielding layer 2022 is used to realize the grounding setting of the first flexible conductive member 11, the second flexible conductive member 12 and the conductive shell of the TOF component 10, which simplifies the grounding structure and the internal structure of the mobile phone 100; the conductive shell of the original TOF component 10 between the two camera modules 3 is used to isolate the antenna transmitting unit 401 and the antenna receiving unit 402, which simplifies the isolation structure and the internal structure of the mobile phone 100.

[0161] There are other grounding methods for the conductive shell of the TOF component 10. For example, the conductive shell of the TOF component 10 can be grounded to the mainboard 6. The conductive shell of the TOF component 10 is directly grounded to the mainboard 6; or the conductive shell of the TOF component 10 is grounded to the mainboard 6 through the grounding part of the elevated circuit board 7 and the support member 8.

[0162] In actual situations, the conductive shell of the TOF component 10 can be grounded to the mainboard 6, and the conductive shell can be grounded to the shielding layer 2022 through the first flexible conductive member 11 and the second flexible conductive member 12. In this way, the conductive shell of the TOF component 10 can be grounded in two ways, thereby improving the grounding reliability of the conductive shell.

[0163] In addition to being grounded to the shielding layer 2022, the first flexible conductive member 11 and the second flexible conductive member 12 may also be grounded in other ways. Exemplarily, the first flexible conductive member 11 and the second flexible conductive member 12 may also be grounded to the mainboard 6 by raising the grounding portion of the circuit board 7 and the support member 8. In this way, the grounding reliability of the first flexible conductive member 11 and the second flexible conductive member 12 is improved.

[0164] As mentioned above, the elevated circuit board 7 needs to be grounded, so the elevated circuit board 7 can be grounded to at least one of the first flexible conductive member 11, the second flexible conductive member 12, and the conductive housing, thereby achieving grounding connection between the elevated circuit board 7 and the shielding layer 2022. In this way, the grounding reliability of the elevated circuit board 7 is improved.

[0165] In the third direction, the length of the first flexible conductive member 11 and the length of the second flexible conductive member 12 are selected according to actual conditions. The longer the length of the first flexible conductive member 11, the better the effect of isolating the antenna transmitting unit 401 and the antenna receiving unit 402; correspondingly, the longer the length of the second flexible conductive member 12, the better the effect of isolating the antenna transmitting unit 401 and the antenna receiving unit 402.

[0166] In the third direction, one end of the first flexible conductive member 11 away from the TOF component 10 exceeds the antenna transmitting unit 401 and the antenna receiving unit 402 , and one end of the second flexible conductive member 12 away from the TOF component 10 exceeds the antenna transmitting unit 401 and the antenna receiving unit 402 .

[0167] In actual situations, it is also possible to select that the end of the first flexible conductive member 11 away from the TOF component 10 extends beyond one of the antenna transmitting unit 401 and the antenna receiving unit 402, and the end of the second flexible conductive member 12 away from the TOF component 10 extends beyond one of the antenna transmitting unit 401 and the antenna receiving unit 402.

[0168] In actual situations, in the third direction, if one end of the conductive housing away from the first flexible conductive member 11 exceeds at least one of the antenna transmitting unit 401 and the antenna receiving unit 402, the second flexible conductive member 12 may not be provided. Correspondingly, if one end of the conductive housing away from the second flexible conductive member 12 exceeds at least one of the antenna transmitting unit 401 and the antenna receiving unit 402, the first flexible conductive member 11 may not be provided.

[0169] In order to improve the effect of isolating the antenna transmitting unit 401 and the antenna receiving unit 402, a third flexible conductive member 13 and a fourth flexible conductive member 14 are further provided on the side of the elevated circuit board 7 close to the display module 2. It can be understood that the third flexible conductive member 13 and the fourth flexible conductive member 14 both protrude from the elevated circuit board 7.

[0170] The types of the third flexible conductive member 13 and the fourth flexible conductive member 14 may refer to the first flexible conductive member 11 and the second flexible conductive member 12 , and will not be further described here.

[0171] The third flexible conductive member 13 and the fourth flexible conductive member 14 are both arranged along the first direction. It should be noted that the length direction of the third flexible conductive member 13 is parallel to the first direction or has an angle therebetween, and the angle is an acute angle. The length direction of the fourth flexible conductive member 14 is parallel to the first direction or has an angle therebetween, and the angle is an acute angle.

[0172] It should be noted that the “parallel” involved in this application refers to “substantially parallel” in actual operation.

[0173] One end of the first flexible conductive member 11 away from the TOF component 10 is grounded to the third flexible conductive member 13 , and one end of the second flexible conductive member 12 away from the TOF component 10 is grounded to the fourth flexible conductive member 14 .

[0174] The first flexible conductive member 11 and the third flexible conductive member 13 may be an integrated structure or a split structure. The second flexible conductive member 12 and the fourth flexible conductive member 14 may be an integrated structure or a split structure.

[0175] The third flexible conductive member 13 and the fourth flexible conductive member 14 are both in contact with the shielding layer 2022 of the display module 2 and are grounded. In this way, the third flexible conductive member 13 and the fourth flexible conductive member 14 increase the contact area with the shielding layer 2022, thereby improving the effect of isolating the antenna transmitting unit 401 and the antenna receiving unit 402.

[0176] In the above structure, the third flexible conductive member 13 and the fourth flexible conductive member 14 are both grounded to the shielding layer 2022. In actual situations, the third flexible conductive member 13 and the fourth flexible conductive member 14 can also be grounded to the mainboard 6 through the grounding portion of the elevated circuit board 7 and the support member 8. In this way, the grounding reliability of the third flexible conductive member 13 and the fourth flexible conductive member 14 is improved; accordingly, the elevated circuit board 7 can be grounded to the shielding layer 2022 through the third flexible conductive member 13 and the fourth flexible conductive member 14, which also improves the grounding reliability of the elevated circuit board 7.

[0177] In the third direction, the positions of the third flexible conductive member 13 and the fourth flexible conductive member 14 on the elevated circuit board 7 can be selected according to actual conditions. Exemplarily, in the third direction, the third flexible conductive member 13 is located at the edge of the elevated circuit board 7, or there is a first preset distance between the third flexible conductive member 13 and the edge of the elevated circuit board 7. In the third direction, the fourth flexible conductive member 14 can be located at the edge of the elevated circuit board 7, or there is a second preset distance between the fourth flexible conductive member 14 and the edge of the elevated circuit board 7. Wherein, both the first preset distance and the second preset distance are greater than zero.

[0178] like Figure 8As shown, in the first direction, two ends of the third flexible conductive member 13 are respectively arranged flush with two ends of the elevated circuit board 7 , and two ends of the fourth flexible conductive member 14 are respectively arranged flush with two ends of the elevated circuit board 7 .

[0179] like Fig. 9 As shown, in the first direction, there is a third preset distance between one end of the third flexible conductive member 13 and the end of the elevated circuit board 7 adjacent thereto, and there is a fourth preset distance between the other end of the third flexible conductive member 13 and the end of the elevated circuit board 7 adjacent thereto. In the first direction, there is a fifth preset distance between one end of the fourth flexible conductive member 14 and the end of the elevated circuit board 7 adjacent thereto, and there is a sixth preset distance between the other end of the fourth flexible conductive member 14 and the end of the elevated circuit board 7 adjacent thereto.

[0180] It should be noted that the third preset distance, the fourth preset distance, the fifth preset distance and the sixth preset distance are all greater than zero.

[0181] Combine the following Fig.10 , illustrating a specific structure for isolating the antenna transmitting unit 401 and the antenna receiving unit 402 when the chip 9 is located on the side of the elevated circuit board 7 close to the display module 2 (the antenna 4 is located on the side of the elevated circuit board 7 close to the display module 2).

[0182] Fig.10 A structure for isolating the antenna transmitting unit 401 and the antenna receiving unit 402 is shown. It should be noted that: Fig.10 The display module 2 is hidden in the figure to display components such as the antenna 4 and the elevated circuit board 7. Fig.10 As shown, the TOF component 10 is located on a side of the elevated circuit board 7 close to the display module 2. For the description of the TOF component 10, please refer to the previous text and will not be repeated here.

[0183] A first flexible conductive member 11 , a second flexible conductive member 12 , a third flexible conductive member 13 and a fourth flexible conductive member 14 are disposed on the elevated circuit board 7 .

[0184] Since the chip 9 is disposed on a side of the elevated circuit board 7 close to the display module 2 , the first flexible conductive member 11 , the second flexible conductive member 12 , the third flexible conductive member 13 , the fourth flexible conductive member 14 and the chip 9 are located on the same side of the elevated circuit board 7 .

[0185] In the third direction, the chip 9 is located on one side of the TOF component 10 , and the second flexible conductive member 12 and the chip 9 are located on the same side of the TOF component 10 , or the first flexible conductive member 11 and the chip 9 are located on the same side of the TOF component 10 .

[0186] In some embodiments, the second flexible conductive member 12 and the chip 9 are located on the same side of the TOF component 10. The description of the first flexible conductive member 11 can be found in the previous text and will not be introduced again here.

[0187] When the chip 9 has no conductive shell, the length of the second flexible conductive member 12 is Figure 6 and Figure 7 The length of the second flexible conductive member 12 shown is different. There is a seventh preset distance between the second flexible conductive member 12 and the chip 9, and the seventh preset distance is greater than zero. The chip 9 is located between the fourth flexible conductive member 14 and the second flexible conductive member 12. The fourth flexible conductive member 14 and the second flexible conductive member 12 are not directly connected to the ground. The fourth flexible conductive member 14 has a buffering and grounding function, but the fourth flexible conductive member 14 does not have a function of isolating the antenna transmitting unit 401 and the antenna receiving unit 402. In the case where the chip 9 has a conductive shell, the second flexible conductive member 12 and the conductive shell can be grounded. For other descriptions of the second flexible conductive member 12, please refer to the previous text (according to Figure 8 and Fig. 9 The part that is explained here will not be introduced here.

[0188] In some other embodiments, the first flexible conductive member 11 and the chip 9 are located on the same side of the TOF component 10. The description of the second flexible conductive member 12 can be found in the above text and will not be introduced again here.

[0189] When the chip 9 has no conductive shell, the length of the first flexible conductive member 11 is Figure 8 and Fig. 9 The length of the first flexible conductive member 11 shown is different. There is an eighth preset distance between the first flexible conductive member 11 and the chip 9, and the eighth preset distance is greater than zero. The chip 9 is located between the first flexible conductive member 11 and the third flexible conductive member 13. The third flexible conductive member 13 and the first flexible conductive member 11 are not directly connected to the ground. The third flexible conductive member 13 has a buffering and grounding function, but the third flexible conductive member 13 does not have the function of isolating the antenna transmitting unit 401 and the antenna receiving unit 402. In the case where the chip 9 has a conductive shell, the first flexible conductive member 11 can be connected to the conductive shell and grounded. Other descriptions of the first flexible conductive member 11 can refer to the above text (according to Figure 8 and Fig. 9 The part that is explained here will not be introduced here.

[0190] For the description of the third flexible conductive member 13 and the fourth flexible conductive member 14, please refer to the above text (according to Figure 8 and Fig. 9 The part for explanation) will not be repeated here.

[0191] It should be noted that the first flexible conductive member 11 can be understood as a part of the flexible conductive component, the second flexible conductive member 12 can be understood as a part of the flexible conductive component, the flexible conductive component can be understood as a part of the first isolation component, and the conductive shell can be understood as a part of the first isolation component. The third flexible conductive member 13 can be understood as a part of the second isolation component, and the fourth flexible conductive member 14 can be understood as a part of the second isolation component.

[0192] In the embodiment of the present application, the distance between the antenna 4 and the camera module 3 is relatively close, so the antenna 4 is more likely to affect the camera module 3. In some embodiments, Fig.11 and Fig.12 The structure shown solves this problem. Fig.11 The structure in which the chip 9 and the antenna 4 are located on the same side of the elevated circuit board 7 and a second isolation component is provided is shown. Fig.12 The structure in which the chip 9 and the antenna 4 are located on different sides of the elevated circuit board 7 and a second isolation component is provided is shown. It should be noted that Fig.11 and Fig.12 The display module 2 is hidden in order to display components such as the antenna 4 and the elevated circuit board 7.

[0193] like Fig.11 and Fig.12 As shown, the elevated circuit board 7 is provided with a fifth flexible conductive member 15, a sixth flexible conductive member 16, the third flexible conductive member 13 mentioned above, and the fourth flexible conductive member 14 mentioned above. The fifth flexible conductive member 15, the third flexible conductive member 13, the sixth flexible conductive member 16, and the fourth flexible conductive member 14 are connected end to end in sequence to form an annular isolation member, which surrounds the entire antenna 4.

[0194] For the types of the fifth flexible conductive member 15 and the sixth flexible conductive member 16 , reference may be made to the first flexible conductive member 11 and the second flexible conductive member 12 , and no further details will be given here.

[0195] The fifth flexible conductive member 15 and the sixth flexible conductive member 16 are both located on the side of the elevated circuit board 7 close to the display module 2, and the fifth flexible conductive member 15 and the sixth flexible conductive member 16 are both grounded to the shielding layer 2022 of the display module 2. Since the third flexible conductive member 13 and the fourth flexible conductive member 14 are also grounded to the shielding layer 2022 of the display module 2, the entire annular isolating member is grounded to the shielding layer 2022 of the display module 2. In this way, the annular isolating member shields the interference of the antenna 4 on the camera module 3, and reduces the influence of the antenna 4 on the camera module 3; the annular isolating member surrounds the antenna 4, and improves the isolation effect of the annular isolating member; the annular isolating member is formed by the third flexible conductive member 13, the fourth flexible conductive member 14, the fifth flexible conductive member 15 and the sixth flexible conductive member 16, which reduces the number of components, improves the compactness of the structure, and simplifies the internal structure of the mobile phone 100.

[0196] In actual situations, the fifth flexible conductive member 15 and the sixth flexible conductive member 16 and other conductive members may also be selected to form an annular isolation member, and the structure is not limited to the above structure.

[0197] It should be noted that the annular isolating member can be understood as a structure of the third isolating component, the fifth flexible conductive member 15 can be understood as a part of the third isolating component, and the sixth flexible conductive member 16 can be understood as a part of the third isolating component. The third isolating component can also be a non-annular structure. For example, the third isolating component includes the fifth flexible conductive member 15 and the sixth flexible conductive member 16. The fifth flexible conductive member 15 and the sixth flexible conductive member 16 reduce the interference of the antenna 4 on the camera module 3, so as to achieve isolation between the antenna 4 and the camera module 3.

[0198] In the above structure, the fifth flexible conductive member 15 and the sixth flexible conductive member 16 are both grounded to the shielding layer 2022. In actual situations, the fifth flexible conductive member 15 and the sixth flexible conductive member 16 can also be grounded to the mainboard 6 through the grounding portion of the elevated circuit board 7 and the support member 8. In this way, the grounding reliability of the fifth flexible conductive member 15 and the sixth flexible conductive member 16 is improved; accordingly, the elevated circuit board 7 can be grounded to the shielding layer 2022 through the fifth flexible conductive member 15 and the sixth flexible conductive member 16, thereby improving the grounding reliability of the elevated circuit board 7.

[0199] In actual situations, the influence of the antenna 4 on the camera module 3 can be reduced by other means. In some other embodiments, the camera module 3 is provided with a grounded anti-interference component (not shown in the figure), so that the structure of the elevated circuit board 7 can be simplified. The anti-interference component is directly connected to the ground of the main board 6; or the anti-interference component is connected to the ground of the elevated circuit board 7, and the elevated circuit board 7 is connected to the ground of the main board 6; or the anti-interference component is connected to the ground of the support component 8, and the support component 8 is connected to the ground of the main board 6. In this way, the impedance of the interference signal return path is reduced, and the interference signal is shielded.

[0200] The anti-interference component may be located between the camera module 3 and the antenna 4 , or the anti-interference component may be disposed outside the camera module 3 and part of the anti-interference component may be located between the camera module 3 and the antenna 4 .

[0201] The shape, size and specific structure of the anti-interference component can be selected according to the actual situation, as long as the anti-interference component is grounded.

[0202] It should be noted that the anti-interference member can also be understood as a structure of the third isolation component. The anti-interference member and the annular isolation member described above can be provided at the same time or separately. In some embodiments, the anti-interference member and the annular isolation member can be provided at the same time, and the anti-interference member and the annular isolation member form a structure of the third isolation component.

[0203] In actual situations, the TOF component 10 can also be replaced with other devices such as a microphone, a speaker, a floodlighting component, or a dot projector, and other devices such as a microphone, a speaker, a floodlighting component, or a dot projector can also be arranged between the antenna transmitting unit 401 and the antenna receiving unit 402. In this embodiment, the other devices such as the microphone, the speaker, the floodlighting component, or the dot projector have the conductive housing described above and play the role of the conductive housing described above.

[0204] In actual situations, there is no TOF component 10, microphone, speaker, floodlight component, dot projector or other devices between the two camera modules 3. In this case, there is no device between the antenna transmitting unit 401 and the antenna receiving unit 402. In an embodiment where there is no device between the antenna transmitting unit 401 and the antenna receiving unit 402, the first flexible conductive member 11 and the second flexible conductive member 12 can be directly connected to the ground to ensure isolation and the antenna transmitting unit 401 and the antenna receiving unit 402. Among them, the first flexible conductive member 11 and the second flexible conductive member 12 can be an integrated structure or a split structure.

[0205] In the embodiment of the present application, the elevated circuit board 7, the antenna 4, the support member 8, the chip 9, the first isolation component, the second isolation component, and the third isolation component can all be understood as part of the antenna component. The antenna component can be understood as part of the mobile phone 100.
