electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 22, 2023, with application number 202311792350.1 and application name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminal equipment, and more specifically, to an electronic device. Background Art

[0003] As users' expectations for electronic device appearance continue to rise, more and more metal-clad devices are appearing on the market. When antennas are deployed on electronic devices (such as mobile phones), the frame forms the antenna radiator, leaving the interior of the device, particularly in the battery area, without an antenna. This results in poor RF performance.

[0004] Summary of the Invention

[0005] The present application provides an electronic device that can deploy an antenna in a battery area, thereby increasing the antenna deployment area and improving the antenna radio frequency performance of the electronic device.

[0006] In a first aspect, an electronic device is provided, comprising a display screen, a middle frame, a back cover, a battery, and a first antenna, wherein the middle frame is located between the display screen and the back cover, the middle frame includes a connecting plate and a frame arranged around the connecting plate, the connecting plate is provided with a battery compartment, and the battery compartment is used to place the battery; the projection of the first antenna on the back cover along a first direction at least partially overlaps with the projection of the battery on the back cover along the first direction, and the first direction is the thickness direction of the electronic device.

[0007] It should be understood that the present application can arrange the antenna in the corresponding area of ​​the battery. That is, the projection of the first antenna along the first direction on the back cover at least partially overlaps with the projection of the battery along the first direction on the back cover.

[0008] In the embodiment of the present application, considering that the battery area is relatively large, by deploying the antenna in the battery area, the deployment area of ​​the antenna can be expanded, thereby increasing the antenna radio frequency performance of the electronic device.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the middle frame is a non-metallic middle frame, the first antenna is located on a side of the connecting plate away from the battery, and along the first direction, the distance between the first antenna and the battery is greater than or equal to a first threshold.

[0010] Exemplarily, the middle frame may be made of plastic.

[0011] Exemplarily, the first threshold may be in the range of 0.2 mm and above, that is, the antenna clearance threshold may be in the range of 0.2 mm and above. It should be noted that the first threshold is frequency-dependent. For example, when millimeter waves are used, the first threshold may be 0.2 mm.

[0012] It should be noted that a space range of 0.2 mm or greater needs to be maintained between the first antenna and the battery. The space range can be a cavity or filled with non-metallic materials.

[0013] In one possible implementation, the first antenna is formed by disposing copper foil, a flexible printed circuit board (FPC), or a steel sheet on the side of the non-metallic middle frame away from the battery. In other words, the antenna radiator can be formed by attaching copper foil, a flexible printed circuit board (FPC), or a steel sheet to the side of the non-metallic middle frame away from the battery.

[0014] It should be understood that FPC antennas are foldable and can be bent into any shape, meeting the increasing demands on electronic device size and design. Therefore, in practical applications, FPC antennas made of liquid crystal polymer (LCP) with excellent high-frequency characteristics can be used.

[0015] In another possible implementation, the first antenna is a metal antenna formed by laser engraving (LDS), electroplating, or spraying on the side of the non-metallic middle frame away from the battery. In other words, the metal antenna radiator can be formed on the side of the non-metallic middle frame away from the battery using LDS, electroplating, or spraying techniques.

[0016] Given the higher requirements for antenna precision and reliability imposed by 5G, LDS antenna technology has become the preferred antenna design solution for electronic devices (such as mobile phones). LDS technology utilizes lasers to directly plate a metal antenna onto a preformed plastic bracket. This technology avoids electromagnetic interference from internal mobile phone components, ensuring a strong signal, while also enhancing space utilization, allowing smartphones to maintain a certain degree of slimness in the 5G era.

[0017] In one possible implementation, the battery compartment opens toward the display screen, and the first antenna is located between the connecting plate and the back cover. It should be understood that placing the first antenna between the connecting plate and the back cover facilitates assembly and maintenance of the first antenna. Furthermore, given the need to maintain a certain distance between the first antenna and the battery, placing the first antenna between the connecting plate and the back cover can also reduce the thickness of the electronic device.

[0018] In one example, the electronic device further includes a main board and a sub-board; the connecting board is provided with a first compartment and a second compartment, the battery compartment is located between the first compartment and the second compartment, the main board is placed in the first compartment, and the sub-board is placed in the second compartment; the first compartment and the second compartment have the same opening direction, while the battery compartment has an opening direction opposite to the first and second compartments. That is, the battery compartment opens toward the display screen, while the first and second compartments both open toward the back cover.

[0019] It should be understood that the motherboard generally integrates electronic components such as processors, memory, flash memory, sensors, etc. The sub-board generally integrates a charging chip for managing the power supply of the electronic device.

[0020] For example, the first storage compartment can also be used to store electronic components such as a main bracket, an antenna, and a speaker. The second storage compartment can also be used to store electronic components such as a secondary bracket, an antenna, and a speaker.

[0021] In this implementation, since only the battery compartment opens toward the display, while the first and second compartments open toward the rear cover, this facilitates inspection and repair of malfunctioning electronic components. Furthermore, the entire midframe can be designed in a "bow" shape, enhancing the rigidity of the midframe and the entire electronic device, increasing product reliability.

[0022] In another example, the electronic device further includes a main board and a sub-board; the connecting board is provided with a first compartment and a second compartment, the battery compartment is located between the first compartment and the second compartment, the main board is placed in the first compartment, and the sub-board is placed in the second compartment; the first compartment and the second compartment have openings in opposite directions, while the first compartment and the battery compartment have openings in the same direction. In other words, the battery compartment and the first compartment open toward the display screen, while the second compartment opens toward the back cover.

[0023] In another example, the electronic device further includes a main board and a sub-board; the connecting board is provided with a first compartment and a second compartment, the battery compartment is located between the first compartment and the second compartment, the main board is placed in the first compartment, and the sub-board is placed in the second compartment; the first compartment and the second compartment open in opposite directions, while the second compartment and the battery compartment open in the same direction. In other words, the battery compartment and the second compartment open toward the display screen, while the first compartment opens toward the back cover.

[0024] In another possible implementation, the opening of the battery compartment faces the back cover, and the first antenna is located between the battery and the back cover.

[0025] In one example, the electronic device further includes a main board and a sub-board; a first compartment and a second compartment are provided on the connecting plate, the battery compartment is located between the first compartment and the second compartment, the main board is placed in the first compartment, and the sub-board is placed in the second compartment; the first compartment and the second compartment have the same opening direction, while the battery compartment has an opening direction opposite to the first and second compartments. That is, the battery compartment opens toward the back cover, while the first and second compartments both open toward the display screen.

[0026] In another example, the electronic device further includes a main board and a sub-board; the connecting board is provided with a first compartment and a second compartment, the battery compartment is located between the first compartment and the second compartment, the main board is placed in the first compartment, and the sub-board is placed in the second compartment; the first compartment and the second compartment have openings in opposite directions, and the first compartment and the battery compartment have openings in the same direction. In other words, the battery compartment and the first compartment open toward the back cover, and the second compartment opens toward the display screen.

[0028] In other implementations, the opening directions of the first placement compartment, the second placement compartment, and the battery compartment can all be the same. In other words, the openings of the first placement compartment, the second placement compartment, and the battery compartment can all face the display screen, or can all face the back cover, without limitation.

[0033] In some embodiments, the first antenna can be connected to the mainboard and / or sub-board via a spring clip; alternatively, the first antenna itself can be bent (such as an FPC antenna) to connect to the mainboard and / or sub-board. In some embodiments, a hole can be drilled in the first compartment, the second compartment, or the battery compartment to allow the first antenna to pass through the connecting plate of the midframe and connect to the mainboard located in the first compartment and / or the sub-board located in the second compartment.

[0034] In combination with the first aspect, in some implementations of the first aspect, the electronic device further includes a first speaker and a second speaker, the first speaker is arranged in the first placement compartment, the second speaker is arranged in the second placement compartment, and the first placement compartment and the second placement compartment are both sealed cavities.

[0035] In this implementation, by setting the first placement chamber and the second placement chamber as sealed cavities, the speakers in the first placement chamber and the second placement chamber will not vibrate with great intensity when playing music, which can reduce the vibration noise generated by the back cover of the electronic device when playing music.

[0036] Exemplarily, the first storage compartment is provided with a connection port, the connection port being used to connect the first storage compartment and the battery compartment. For example, the connection port is provided on the top of the first storage compartment, or on the side of the first storage compartment.

[0038] Exemplarily, the second antenna can be placed in the first placement compartment, in which case the second antenna can be fixed to the main bracket; the third antenna can be placed in the second placement compartment, in which case the third antenna can be fixed to the secondary bracket.

In addition, in the description of this embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0081] The terms "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", etc. in the embodiments of the present application indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the present application.

Thus, phrases such as "in some embodiments" and the like that appear in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0083] The “perpendicular” mentioned in this application is not strictly perpendicular, but within the allowable error range. The “parallel” is not strictly parallel, but within the allowable error range.

[0084] In the embodiments of this application, the same reference numerals represent the same component or part. In the embodiments of this application, for multiple identical parts, only one of the parts may be labeled with a reference numeral in the drawings as an example. The same reference numerals apply to other identical parts or components. In addition, the sizes and dimensions of the parts shown in the drawings are for illustrative purposes only.

[0085] The embodiments of the present application define the coordinate system of the accompanying drawings. The x-direction, y-direction, and z-direction are perpendicular to each other. The z-direction can be understood as the thickness direction of the electronic device, the y-direction can be understood as the width direction of the electronic device, and the x-direction can be understood as the length direction of the electronic device. Alternatively, the y-direction can be understood as the length direction of the electronic device, and the x-direction can be understood as the width direction of the electronic device. For example, in the embodiments of the present application, the structure of the electronic device is described by taking the y-direction as the length direction of the electronic device and the x-direction as the width direction of the electronic device as an example.

[0086] When designing the overall architecture of electronic devices (such as mobile phones), the layout is mainly based on the structure of the midframe. Mainstream electronic devices mainly have the following two architectures:

[0087] In one possible electronic device architecture, the electronic device includes a display, a middle frame, and a back cover. The side of the middle frame facing the display can be called the middle frame T-side, and the side of the middle frame facing the back cover can be called the middle frame B-side. During assembly, the display can be assembled on the middle frame T-side, and the battery, motherboard, antenna, speaker, back cover, and other components can be assembled on the middle frame B-side. With this architectural design, the layout of the various components is relatively simple. When the battery, motherboard, speaker, etc. fail, the back panel can be removed from the middle frame, and the various electronic components inside can be repaired or replaced. However, with this layout structure, the side of the battery closest to the back cover is only protected by the back cover. Therefore, the back cover must have a certain thickness, and the thickness of the back cover affects the thickness of the entire device, resulting in a thicker electronic device. In addition, the area on the middle frame B-side where the battery is mounted cannot be used for the antenna, the middle frame has poor rigidity, and the back cover is prone to vibration and noise when the phone plays music.

[0088] In another possible electronic device architecture, the electronic device includes a display, a middle frame, and a back cover. The side of the middle frame facing the display can be called the middle frame T-side, and the side of the middle frame facing the back cover can be called the middle frame B-side. During assembly, components such as the display, battery, motherboard, antenna, and speaker can be assembled on the middle frame T-side, and the back cover can be assembled on the middle frame B-side. This architectural design allows for a thinner design because the middle frame and display protect the internal electronic components, thereby reducing the thickness of the entire electronic device. However, with this layout, the internal electronic components must be installed before the display. However, if the battery, motherboard, or speaker malfunctions, the display must be removed from the middle frame before repairing or replacing the internal electronic components. This results in poor manufacturing maintainability and high costs for this electronic device. Furthermore, the area on the middle frame T-side where the battery is mounted cannot accommodate the antenna, resulting in poor middle frame rigidity. Furthermore, the screen is prone to vibration and noise when playing music on the phone.

[0089] Therefore, the present application provides an electronic device that, by adopting a new design architecture, can increase the antenna layout area, increase the antenna RF performance of the electronic device, improve the stiffness of the middle frame, and reduce the vibration noise generated when the electronic device plays music.

[0090] It should be noted that the electronic devices involved in the embodiments of the present application may include mobile terminals such as mobile phones, wearable devices, smart watches, tablet computers, e-readers, notebook computers, laptop computers, mobile computers, augmented reality devices, virtual reality devices, and handheld game consoles, etc. In the following embodiments, the electronic device is described as a mobile phone.

Figure 2 is an exploded view of the electronic device 100 shown in Figure 1 , and Figure 3 is a schematic diagram of the cross-sectional structure of the electronic device 100 shown in Figure 1 or Figure 2 .

[0092] As can be seen from Figures 1 to 3, the electronic device 100 may include a display screen 110, a middle frame 120, and a back cover 130, with the display screen 110 and the back cover 130 respectively located on both sides of the middle frame 120. A first accommodating cavity may be formed between the middle frame 120 and the display screen 110, and a second accommodating cavity may be formed between the middle frame 120 and the back cover 130. It should be understood that some electronic components inside the electronic device 100, such as a heat dissipation module 140, a battery 150, a circuit board 160, a bracket 170, and an antenna 180, may be placed in the first accommodating cavity and the second accommodating cavity. The heat dissipation module 140 and the battery 150 may be located in the first accommodating cavity, and the heat dissipation module 140 may be attached to the display screen 110 to dissipate heat from the display screen 110. The circuit board 160, the bracket 170, and the antenna 180 may be located in the second accommodating cavity.

[0093] For example, with the middle frame 120 as the boundary, the side of the middle frame 120 facing the display screen 110 can be called the middle frame T-side, and the side of the middle frame 120 facing the back cover 130 can be called the middle frame B-side. The heat dissipation module 140 and battery 150 can be located in the first accommodation cavity enclosed by the middle frame T-side and the display screen 110, while the circuit board 160, bracket 170, and antenna 180 can be located in the second accommodation cavity enclosed by the middle frame B-side and the back cover 130.

[0094] In some embodiments, as shown in Figure 3, the middle frame 120 may include a frame 121 and a connecting plate 122, the connecting plate 122 is arranged in the frame 121, and the frame 121 is arranged around the connecting plate 122. For example, the connecting plate 122 may be perpendicular to the frame 121, or the connecting plate 122 may be at other angles not equal to 90 degrees with the frame. The display screen 110 is arranged on one side of the middle frame 120 and is connected to the frame 121 on the middle frame 120; the back cover 130 is arranged on the other side of the middle frame 120 and is connected to the frame 121 on the middle frame 120. The display screen 110, the middle frame 120 and the back cover 130 form a closed space, and the structure formed by them is the appearance of the electronic device 100.

[0095] The connecting plate 122 has a concave-convex structure. For example, the middle portion of the connecting plate 122 may be recessed downward, that is, recessed toward the side closest to the rear cover 130, to form a battery compartment. Since the connecting plate 122 is connected to the frame 121, the sidewalls on either side of the battery compartment and the frame 121 form a first placement compartment and a second placement compartment, respectively. The battery compartment is used to hold the battery 150, and the first and second placement compartments are used to hold other electronic components, such as the circuit board 160, bracket 170, and antenna 180.

[0096] It should be noted that the above positions of the first placement compartment, the second placement compartment, and the battery compartment are merely exemplary. In other embodiments, the battery compartment may not be disposed between the first placement compartment and the second placement compartment, but may be disposed near the frame 121.

[0097] In the structure shown in Figure 3, the opening direction of the first storage compartment is the same as the opening direction of the second storage compartment, and opposite to the opening direction of the battery compartment. In other words, the entire middle frame 120 can be designed into a "bow" structure, thereby improving the rigidity of the middle frame 120 and the entire electronic device 100, and enhancing product reliability. It should be understood that the battery compartment is part of the first accommodating cavity, and the first and second storage compartments are part of the second accommodating cavity.

[0098] For example, as shown in FIG2 or FIG3, the battery 150 can be disposed in the first accommodating cavity, that is, the battery 150 can be disposed in the accommodating space enclosed by the middle frame 120 and the display screen 110. Specifically, the battery 150 can be disposed in the battery compartment. The circuit board 160 includes a main board 161 and a sub-board 162. The main board 161 can be placed in the first placement compartment, and the sub-board 162 can be placed in the second placement compartment. The main board 161 can be fixed to the connecting plate 122 in the first placement compartment by screws, and the sub-board 162 can also be fixed to the connecting plate 122 in the second placement compartment by screws.

[0099] It should be noted that the circuit board 160 (including the main board 161 and the auxiliary board 162) in this application can refer to a printed circuit board (PCB) or other circuit boards, and this application is not limited to this. The main board 161 generally integrates electronic components such as a processor, memory, flash memory, and sensors. The auxiliary board 162 generally integrates a charging chip for managing the power supply of the electronic device.

[0100] In the electronic device 100, the battery 150 is used to power the electronic components on the circuit board 160, and the opening direction of the battery compartment is opposite to the opening direction of the first placement compartment or the second placement compartment. Therefore, it is necessary to dig a hole between the battery compartment for placing the battery 150 and the first placement compartment for placing the main board 161 (or the second placement compartment for placing the auxiliary board 162) so that the connector of the battery 150 can pass through and connect to the main board 161 (or auxiliary board 162). For example, as shown in Figure 3, a connection port 1221 is provided at the top of the first placement compartment. The connection port 1221 is located near the battery compartment to reduce the length of the connection line between the battery 150 and the main board 161. In other words, the connector on the battery 150 can pass through the connection port 1221 at the top of the first placement compartment and connect to the main board 161 in the first placement compartment.

[0101] In addition, the connection port can also be opened in other positions, for example, a connection port is opened on the side of the first placement compartment, and the connection port can directly connect the battery compartment and the first placement compartment. The connector on the battery 150 can be connected to the mainboard 161 in the first placement compartment through the connection port set on the side. The specific setting position of the connection port needs to be determined according to the position of the connector on the battery 150. For example, the connector can be set at the bottom of the battery 150, and then the connection port can be set on the side of the battery compartment and the first placement compartment and close to the bottom of the battery compartment.

[0102] In some embodiments, when the battery 150 is placed in the battery compartment, the position of the connector on the battery 150 can be substantially flush with the position of the connection port 1221, allowing the connector to pass straight through the connection port 1221 and connect to the mainboard 161 in the first compartment, thereby simplifying and facilitating the connection between the battery 150 and the mainboard 161. The size of the connection port 1221 can be adjusted based on the size of the connector, and is generally slightly larger than the connector.

[0103] The bracket 170 includes a main bracket 171 and a sub-bracket 172. The main bracket 171 can be placed in the first placement compartment and is located on the side of the main board 161 away from the display screen 110, and can be used to support the main board 161 and the antenna located in the first placement compartment; the sub-bracket 172 can be placed in the second placement compartment and is located on the side of the sub-board 162 away from the display screen 110, and can be used to support the sub-board 162 and the antenna located in the second placement compartment.

[0104] The antenna 180 can be arranged in the second accommodating cavity, that is, arranged in the accommodating space enclosed by the middle frame 120 and the back cover 130. In order to arrange the antenna 180 over a large area, in the embodiment of the present application, the antenna 180 can be arranged in the corresponding areas of the first placement compartment, the second placement compartment, and the battery compartment to increase the antenna RF performance of the electronic device 100. It should be noted that in other embodiments, in order to arrange the antenna 180 over a large area and enhance the antenna RF performance, the antenna 180 can be laid on the entire surface of the second accommodating cavity, that is, the antenna 180 can be laid on the entire surface between the middle frame 120 and the back cover 130.

[0105] Exemplarily, the antenna 180 may include a first antenna 181, a second antenna 182, and a third antenna 183. The first antenna 181 may be disposed in a corresponding area of ​​the battery compartment, which may be understood as an area where the first antenna 181 overlaps with the projection of the battery compartment along the z-direction. That is, the first antenna 181 may be disposed between the connecting plate 122 and the back cover 130, and the projection of the first antenna 181 along the z-direction on the back cover 130 at least partially overlaps with the projection of the battery compartment (or battery 150) along the z-direction on the back cover 130, where the z-direction is the thickness direction of the electronic device 100.

[0106] The second antenna 182 can be arranged in the first placement compartment and can be located on a side of the main bracket 171 away from the display screen 110. For example, the second antenna 182 can be fixed to the main bracket 171. The projection of the second antenna 182 on the back cover 130 along the first direction (i.e., the z-direction) at least partially overlaps with the projection of the first placement compartment on the back cover 130 along the first direction.

[0107] The third antenna 183 can be arranged in the second placement compartment and can be located on a side of the sub-bracket 172 away from the display screen 110. For example, the third antenna 183 can be fixed to the sub-bracket 172. The projection of the third antenna 183 on the back cover 130 along the first direction at least partially overlaps with the projection of the second placement compartment on the back cover 130 along the first direction.

[0108] Exemplarily, the frame 121 can be made directly of metal and serve as an antenna radiator. That is, the frame 121 can be a metal frame, and the metal frame can serve as an antenna radiator. It should be understood that in some embodiments, the second antenna 182 and the third antenna 183 may not be provided, and the metal frame can be directly used as the antenna radiator. That is, the frame 121 can be a metal frame, and the metal frame can serve as the antenna radiator. In other embodiments, the electronic device may also use a metal frame as the antenna radiator while providing the second antenna 182 and / or the third antenna 183, and this application does not limit this.

[0109] In some embodiments, the antenna 180 may include only the first antenna 181, which may be arranged in the area corresponding to the battery compartment. That is, the first antenna 181 is arranged between the connecting plate 122 and the back cover 130, and the projection of the first antenna 181 along the z-direction on the back cover 130 overlaps with the projection of the battery compartment (or battery 150) along the z-direction on the back cover 130. It should be understood that, considering the large area of ​​the battery area, by arranging the antenna in the battery area, the antenna arrangement area can be expanded, thereby improving the antenna RF performance of the electronic device.

[0110] In some embodiments, the middle frame 120 may be a non-metallic middle frame, for example, the middle frame 120 is a plastic middle frame, and the first antenna 181 may be located on a side of the connecting plate 122 away from the battery 150, and along the first direction (i.e., the z-direction), the distance between the first antenna 181 and the battery 150 is greater than or equal to a first threshold. The projection of the first antenna 181 on the back cover 130 along the first direction at least partially overlaps with the projection of the battery 150 on the back cover 130 along the first direction. It should be understood that by arranging the first antenna 181 on the side of the connecting plate 122 away from the battery 150, the assembly and maintenance of the first antenna 181 are facilitated. In addition, considering that a certain distance needs to be maintained between the first antenna 181 and the battery 150, the thickness of the electronic device can also be reduced by arranging the first antenna 181 on the side of the connecting plate 122 away from the battery 150. In other embodiments, the first antenna 181 may be located on a side of the connecting plate 122 close to the battery 150. A certain distance (e.g., a first threshold) must be maintained between the battery 150 and the first antenna 181, and the projection of the first antenna 181 along the first direction on the back cover 130 at least partially overlaps with the projection of the battery 150 along the first direction on the back cover 130. Therefore, in this case, the thickness of the electronic device will increase to a certain extent.

[0111] Exemplarily, the first threshold may be in the range of 0.2 mm and above, that is, the antenna clearance threshold may be in the range of 0.2 mm and above. It should be noted that the first threshold is frequency-dependent. For example, when millimeter waves are used, the first threshold may be 0.2 mm.

[0112] It should be noted that a space range of 0.2 mm or greater needs to be maintained between the first antenna 181 and the battery 150 , and the space range can be a cavity or filled with non-metallic materials.

[0113] In one example, the first antenna 181 is formed by placing copper foil, a flexible printed circuit (FPC), or a steel sheet on the side of the non-metallic middle frame away from the battery 150. In other words, the antenna radiator can be formed by attaching copper foil, FPC, or a steel sheet to the side of the non-metallic middle frame away from the battery.

[0114] It should be understood that FPC antennas are foldable and can be bent into any shape, meeting the increasing demands on electronic device size and design. Therefore, in practical applications, FPC antennas made of liquid crystal polymer (LCP) with excellent high-frequency characteristics can be used.

[0115] In another example, the first antenna 181 is a metal antenna formed by laser direct structuring (LDS), electroplating, or sputtering on the side of the non-metallic midframe away from the battery 150. In other words, a metal antenna radiator can be formed on the side of the non-metallic midframe away from the battery 150 using LDS, electroplating, or sputtering techniques.

[0116] Given the higher requirements for antenna precision and reliability imposed by 5G, LDS antenna technology has become the preferred antenna design solution for electronic devices (such as mobile phones). LDS technology utilizes lasers to directly plate a metal antenna onto a preformed plastic bracket. This technology avoids electromagnetic interference from internal mobile phone components, ensuring a strong signal, while also enhancing space utilization, allowing smartphones to maintain a certain degree of slimness in the 5G era.

[0117] It should be noted that, in one example, the first antenna 181 may extend to the area where the main board 161 is located and be connected to the main board 161. In another example, the first antenna 181 may extend to the area where the secondary board 162 is located and be connected to the secondary board 162. In yet another example, one end of the first antenna 181 may extend to the area where the main board 161 is located and be connected to the main board 161, and the other end of the first antenna 181 may extend to the area where the secondary board 162 is located and be connected to the secondary board 162.

[0118] In some embodiments, the first antenna 181 can be connected to the mainboard 161 and / or the sub-board 162 via a spring clip; alternatively, the first antenna 181 itself can be bent (such as an FPC antenna) to connect to the mainboard 161 and / or the sub-board 162. In some embodiments, a hole can be drilled in the first placement compartment, the second placement compartment, or the battery compartment to allow the first antenna 181 to pass through the connecting plate 122 of the middle frame 120 and connect to the mainboard 161 located in the first placement compartment and / or the sub-board 162 located in the second placement compartment.

[0119] It should be understood that the second antenna 182 and the third antenna 183 may also be connected to the main board 161 and / or the sub-board 162 in a similar manner.

[0120] When the electronic device 100 employs the structure shown in FIG3 , only the battery compartment opens toward the display screen 110, while the first and second compartments both open toward the back cover 130. Therefore, the display screen 110 only needs to be removed when the electronic components within the battery compartment need to be repaired or replaced. If other electronic components within the electronic device 100 malfunction, opening the back cover 130 allows access to the first and second compartments, making it easy to replace or repair the components within. Since the battery compartment typically only contains the battery 150, which has a long service life, replacement frequency is low. In other words, the probability of needing to remove the display screen 110 is generally low, and malfunctions within the electronic device 100 are typically caused by other electronic components, which are typically located in the first and second compartments. Therefore, when a malfunction occurs within the electronic device 100, most malfunctions can be inspected and repaired by removing the back cover 130. Compared with removing the display screen 110 from the middle frame 120 , removing the back cover 130 is simpler and more convenient.

[0121] Furthermore, the antenna 180 can be placed over most of the second cavity, i.e., in the corresponding areas of the first compartment, the battery compartment, and the second compartment, thereby enhancing the antenna RF performance of the electronic device 100. Furthermore, the entire midframe 120 can be designed in a "bow" shape, thereby increasing the rigidity of the midframe 120 and the entire electronic device 100, and enhancing product reliability.

[0122] Figure 4 is a schematic cross-sectional view of another electronic device provided in an embodiment of the present application. The main difference between the electronic device shown in Figure 4 and the electronic device shown in Figure 3 is that the opening direction of the second placement compartment is different, resulting in a difference in the architecture of the entire electronic device.

[0123] Specifically, in the structure shown in FIG. 4 , the opening direction of the first placement compartment is different from the opening direction of the second placement compartment, and the opening direction of the second placement compartment is the same as the opening direction of the battery compartment, both facing the display screen 110 .

[0124] As shown in Figure 4, the middle frame 120 may include a frame 121 and a connecting plate 122, and the connecting plate 122 has a concave-convex structure. Specifically, the middle part of the connecting plate 122 can be recessed downward to form a battery compartment; a portion of the connecting plate 122 close to the frame 121 can be recessed downward to form a second placement compartment, and the battery compartment and the second placement compartment can be separated by the connecting plate 122, so that the battery compartment and the second placement compartment have relatively independent spaces; a first placement compartment is formed between the other side of the battery compartment and the frame 121. The battery compartment is used to place batteries 150, and the first placement compartment and the second placement compartment are used to place other electronic components, for example, electronic components such as a circuit board 160, a bracket 170 and an antenna 180. It should be understood that the battery compartment and the second placement compartment are part of the first accommodating cavity, and the first placement compartment is part of the second accommodating cavity.

[0125] For example, the battery 150 can be disposed in the first accommodating cavity, that is, the battery 150 can be disposed in the accommodating space enclosed by the middle frame 120 and the display screen 110. Specifically, the battery 150 can be disposed in the battery compartment. The circuit board 160 includes a main board 161 and a sub-board 162. The main board 161 can be placed in the first placement compartment, and the sub-board 162 can be placed in the second placement compartment. The main board 161 can be fixed to the connecting plate 122 in the first placement compartment by screws, and the sub-board 162 can also be fixed to the connecting plate 122 in the second placement compartment by screws.

[0126] The bracket 170 can be fixedly connected to the middle frame 120. The bracket 170 includes a main bracket 171 and a sub-bracket 172. The main bracket 171 can be located in the first placement compartment. The main bracket 171 is located on the side of the main board 161 away from the display screen 110, and can be used to support the main board 161 and the antenna (such as the second antenna 182) located in the first placement compartment; the sub-bracket 172 can be located in the second placement compartment. The sub-bracket 172 is located on the side of the sub-board 162 close to the display screen 110, and can be used to support the sub-board 162.

[0127] The antenna 180 can be arranged in the second accommodating cavity, that is, arranged in the accommodating space enclosed by the middle frame 120 and the back cover 130. In order to arrange the antenna 180 over a large area, in the embodiment of the present application, the antenna 180 can be arranged in the corresponding areas of the first placement compartment, the second placement compartment, and the corresponding area of ​​the battery compartment to increase the antenna RF performance of the electronic device 100. It should be noted that in other embodiments, in order to arrange the antenna 180 over a large area and enhance the antenna RF performance, the antenna 180 can be laid on the entire surface of the second accommodating cavity, that is, the antenna 180 can be laid on the entire surface between the middle frame 120 and the back cover 130.

[0128] Exemplarily, the antenna 180 may include a first antenna 181, a second antenna 182, and a third antenna 183. The first antenna 181 may be disposed in a corresponding area of ​​the battery compartment, which may be understood as the area where the first antenna 181 and the battery compartment overlap along the z-direction projection. That is, the first antenna 181 is disposed between the connecting plate 122 and the back cover 130, and the projection of the first antenna 181 along the z-direction on the back cover 130 at least partially overlaps with the projection of the battery compartment (or battery 150) along the z-direction on the back cover 130, where the z-direction is the thickness direction of the electronic device 100.

[0129] The second antenna 182 can be arranged in the first placement compartment and located on a side of the main bracket 171 away from the display screen 110. For example, the second antenna 182 can be fixed to the main bracket 171. The projection of the second antenna 182 along the first direction (i.e., the z-direction) on the back cover 130 at least partially overlaps with the projection of the first placement compartment along the first direction on the back cover 130.

[0130] The third antenna 183 can be arranged in a corresponding area of ​​the second placement compartment. The corresponding area of ​​the second placement compartment can be understood as the area where the projections of the third antenna 183 and the second placement compartment overlap along the z-direction. Furthermore, the third antenna 183 can be located between the middle frame 120 and the back cover 130. For example, the third antenna 183 can be fixed to the side of the middle frame 120 away from the display 110. The projection of the third antenna 183 along the first direction onto the back cover 130 at least partially overlaps with the projection of the second placement compartment along the first direction onto the back cover 130.

[0131] It should be understood that the above mainly introduces the differences between the electronic device shown in FIG. 4 and the electronic device shown in FIG. 3 , and the same contents between the two will not be repeated.

[0132] When the electronic device 100 adopts the architecture shown in Figure 4, the antenna 180 can be laid out in most areas of the second accommodating cavity, that is, the corresponding areas of the first storage compartment, the corresponding areas of the battery compartment, and the corresponding areas of the second storage compartment can all be arranged with the antenna 180, thereby improving the antenna RF performance of the electronic device 100. In addition, the concave and convex structure of the connecting plate 122 of the middle frame 120 can also improve the rigidity of the middle frame 120 and the entire electronic device 100 to a certain extent, increasing product reliability.

[0133] Figure 5 is a schematic cross-sectional view of another electronic device provided in an embodiment of the present application. The main difference between the electronic device shown in Figure 5 and the electronic device shown in Figure 3 is that the opening direction of the first placement compartment is different, resulting in a difference in the architecture of the entire electronic device.

[0134] Specifically, in the structure shown in FIG. 5 , the opening direction of the first placement compartment is different from the opening direction of the second placement compartment, and the opening direction of the first placement compartment is the same as the opening direction of the battery compartment, both facing the display screen 110 .

[0135] As shown in Figure 5, the middle frame 120 may include a frame 121 and a connecting plate 122, and the connecting plate 122 has a concave-convex structure. Specifically, the middle part of the connecting plate 122 can be recessed downward to form a battery compartment; a portion of the connecting plate 122 close to the frame 121 can be recessed downward to form a first placement compartment, and the battery compartment and the first placement compartment can be separated by the connecting plate 122, so that the battery compartment and the first placement compartment have relatively independent spaces; a second placement compartment is formed between the other side of the battery compartment and the frame 121. The battery compartment is used to place batteries 150, and the first placement compartment and the second placement compartment are used to place other electronic components, for example, electronic components such as a circuit board 160, a bracket 170 and an antenna 180. It should be understood that the battery compartment and the first placement compartment are part of the first accommodating cavity, and the second placement compartment is part of the second accommodating cavity.

[0136] For example, the battery 150 can be disposed in the first accommodating cavity, that is, the battery 150 can be disposed in the accommodating space enclosed by the middle frame 120 and the display screen 110. Specifically, the battery 150 can be disposed in the battery compartment. The circuit board 160 includes a main board 161 and a sub-board 162. The main board 161 can be placed in the first placement compartment, and the sub-board 162 can be placed in the second placement compartment. The main board 161 can be fixed to the connecting plate 122 in the first placement compartment by screws, and the sub-board 162 can also be fixed to the connecting plate 122 in the second placement compartment by screws.

[0137] The bracket 170 includes a main bracket 171 and a sub-bracket 172. The main bracket 171 can be located in the first placement compartment. The main bracket 171 can be located on the side of the main board 161 close to the display screen 110, and can be used to support the main board 161. The sub-bracket 172 can be located in the second placement compartment; the sub-bracket 172 can be located on the side of the sub-board 162 close to the display screen 110, and can be used to support the sub-board 162 and the antenna (such as the third antenna 183) located in the second placement compartment.

[0138] The antenna 180 can be arranged in the second accommodating cavity, that is, arranged in the accommodating space enclosed by the middle frame 120 and the back cover 130. In order to arrange the antenna 180 over a large area, in the embodiment of the present application, the antenna 180 can be arranged in the corresponding area of ​​the first placement compartment, the second placement compartment, and the corresponding area of ​​the battery compartment to increase the antenna RF performance of the electronic device 100. It should be noted that in other embodiments, in order to arrange the antenna 180 over a large area and enhance the antenna RF performance, the antenna 180 can be laid on the entire surface of the second accommodating cavity, that is, the antenna 180 can be laid on the entire surface between the middle frame 120 and the back cover 130.

[0139] Exemplarily, the antenna 180 may include a first antenna 181, a second antenna 182, and a third antenna 183. The first antenna 181 may be disposed in a corresponding area of ​​the battery compartment, which can be understood as the area where the first antenna 181 and the battery compartment overlap along the z-direction. That is, the first antenna 181 is disposed between the connecting plate 122 and the back cover 130, and the projection of the first antenna 181 along the z-direction on the back cover 130 at least partially overlaps with the projection of the battery compartment along the z-direction on the back cover 130. The z-direction is the thickness direction of the electronic device 100.

[0140] The second antenna 182 can be arranged in a corresponding area of ​​the first placement compartment. The corresponding area of ​​the first placement compartment can be understood as the area where the second antenna 182 and the first placement compartment's projection along the z-direction overlap. Furthermore, the second antenna 182 can be located on the side of the middle frame 120 away from the display screen 110. For example, the second antenna 182 can be attached to the side of the middle frame 120 away from the display screen 110. The projection of the second antenna 182 along the first direction (i.e., the z-direction) on the back cover 130 at least partially overlaps with the projection of the first placement compartment on the back cover 130 along the first direction.

[0141] The third antenna 183 can be arranged in the second placement compartment and can be located on a side of the sub-bracket 172 away from the display screen 110. For example, the third antenna 183 can be fixed to the sub-bracket 172. The projection of the third antenna 183 on the back cover 130 along the first direction at least partially overlaps with the projection of the second placement compartment on the back cover 130 along the first direction.

[0142] It should be understood that the above mainly introduces the differences between the electronic device shown in FIG5 and the electronic device shown in FIG3 , and the same contents between the two will not be repeated.

[0143] When the electronic device 100 adopts the architecture shown in Figure 5, the antenna 180 can be placed in most areas of the second accommodating cavity, that is, the corresponding areas of the first storage compartment, the corresponding areas of the battery compartment, and the second storage compartment can all be placed with the antenna 180, thereby improving the antenna RF performance of the electronic device 100. In addition, the concave and convex structure of the connecting plate 122 of the middle frame 120 can also improve the rigidity of the middle frame 120 and the entire electronic device 100 to a certain extent, increasing product reliability.

[0144] FIG6 is a schematic diagram showing the assembly process of the electronic device shown in FIG3 . First, as shown in (a) in FIG6 , the battery 150 can be loaded into the battery compartment of the first accommodating cavity, that is, the battery 150 can be installed in a position close to the T-surface of the middle frame. Secondly, as shown in (b) in FIG6 , the screen assembly can be installed in the first accommodating cavity, that is, the screen assembly can be installed in a position close to the T-surface of the middle frame, wherein the screen assembly can include a display screen 110 and a heat dissipation module 140. Thirdly, as shown in (c) in FIG6 , electronic components (such as a circuit board 160, a bracket 170 and an antenna 180) can be installed in the second accommodating cavity. Specifically, the main board 161, the main bracket 171 and the second antenna 182 can be placed in the first placement compartment, the sub-board 162, the sub-bracket 172 and the third antenna 183 can be placed in the second placement compartment, and the first antenna 181 can be set in the corresponding area of ​​the battery compartment. Finally, as shown in (d) in Figure 6, the back cover 130 can be installed at a position close to the middle frame B surface, that is, the back cover 130 is installed on the side of the antenna 180 away from the display screen 110, and the side of the back cover 130 is fixedly connected to the border 121 of the middle frame 120.

[0145] As can be seen from the assembly process of the electronic device 100 described above, the battery 150 is installed in the battery compartment, with its opening facing the display screen 110. Most of the electronic components of the electronic device 100 are installed in the first and second compartments, both of which open toward the back cover 130. The battery 150 has a long service life and requires less frequent replacement. Therefore, if other electronic components within the electronic device 100 malfunction, opening the back cover 130 allows access to the first and second compartments, allowing for convenient replacement or repair of the internal electronic components. This is a simple and convenient operation.

[0146] Furthermore, antennas 180 can be placed in the corresponding areas of the first compartment, the battery compartment, and the second compartment, thereby expanding the antenna 180 placement area and improving the antenna RF performance of electronic device 100. Furthermore, the "bow"-shaped design of the entire midframe 120 also enhances the rigidity of midframe 120 and the entire electronic device 100, increasing product reliability.

[0147] Figure 7 is a schematic cross-sectional view of another electronic device provided in an embodiment of the present application. The main difference between the electronic device shown in Figure 7 and the electronic device shown in Figure 3 is that the opening directions of the battery compartment, the first storage compartment, and the second storage compartment are all different, resulting in a different architecture of the entire electronic device.

[0148] Specifically, in the structure shown in FIG7 , the opening direction of the first storage compartment is the same as the opening direction of the second storage compartment, and the opening direction of the first storage compartment and the opening direction of the second storage compartment are different from the opening direction of the battery compartment. The battery compartment opens toward the rear cover 130, and the second storage compartment opens toward the display screen 110. The opening of the second storage compartment also faces the display screen 110.

[0149] As shown in Figure 7, the middle frame 120 may include a frame 121 and a connecting plate 122, and the connecting plate 122 has a concave-convex structure. Specifically, the middle part of the connecting plate 122 can bulge upward, that is, bulge toward the display screen 110, to form a battery compartment. Since the connecting plate 122 is connected to the frame 121, the side walls and the frame 121 on both sides of the battery compartment form a first placement compartment and a second placement compartment respectively. The battery compartment is used to place the battery 150, and the first placement compartment and the second placement compartment are used to place other electronic components, for example, electronic components such as the circuit board 160, the bracket 170 and the antenna 180. It should be understood that the first placement compartment and the second placement compartment are part of the first accommodating cavity, and the battery compartment is part of the second accommodating cavity.

[0150] For example, the battery 150 can be placed in the second accommodating cavity, that is, the battery 150 can be placed in the accommodating space enclosed by the middle frame 120 and the back cover 130. Specifically, the battery 150 can be placed in the battery compartment. The circuit board 160 includes a main board 161 and a sub-board 162. The main board 161 can be placed in the first placement compartment, and the sub-board 162 can be placed in the second placement compartment. The main board 161 can be fixed to the connecting plate 122 in the first placement compartment by screws, and the sub-board 162 can also be fixed to the connecting plate 122 in the second placement compartment by screws.

[0151] The bracket 170 includes a main bracket 171 and a sub-bracket 172. The main bracket 171 can be located in the first placement compartment, and the main bracket 171 is located on the side of the main board 161 away from the display screen 110, and can be used to support the main board 161; the sub-bracket 172 can be located in the second placement compartment, and the sub-bracket 172 is located on the side of the sub-board 162 away from the display screen 110, and can be used to support the sub-board 162.

[0152] The antenna 180 can be arranged in the second accommodating cavity, that is, arranged in the accommodating space enclosed by the middle frame 120 and the back cover 130. In order to arrange the antenna 180 over a large area, in an embodiment of the present application, the antenna 180 can be arranged in the corresponding area of ​​the first placement compartment, the corresponding area of ​​the second placement compartment, and the corresponding area of ​​the battery compartment to increase the antenna RF performance of the electronic device 100. It should be noted that in other embodiments, in order to arrange the antenna 180 over a large area and enhance the antenna RF performance, the antenna 180 can be laid on the entire surface of the second accommodating cavity, that is, the antenna 180 can be laid on the entire surface between the middle frame 120 and the back cover 130.

[0153] For example, the antenna 180 may include a second antenna 182, a third antenna 183, and a first antenna 181. The first antenna 181 may be disposed within the battery compartment and between the battery 150 and the back cover 130. The projection of the first antenna 181 along the z-direction on the back cover 130 at least partially overlaps with the projection of the battery compartment (or battery 150) along the z-direction on the back cover 130.

[0154] The second antenna 182 can be arranged in the corresponding area of ​​the first placement compartment. The corresponding area of ​​the first placement compartment can be understood as the area where the second antenna 182 and the first placement compartment's projections overlap along the z-direction. Furthermore, the second antenna 182 can be located between the connecting plate 122 and the back cover 130. For example, the second antenna 182 can be fixed to the side of the middle frame 120 away from the display 110. The projection of the second antenna 182 along the z-direction on the back cover 130 at least partially overlaps with the projection of the first placement compartment along the z-direction on the back cover 130.

[0155] The third antenna 183 can be arranged in the corresponding area of ​​the second placement compartment. The corresponding area of ​​the second placement compartment can be understood as the area where the projections of the third antenna 183 and the second placement compartment overlap along the z-direction. Furthermore, the third antenna 183 can be arranged between the connecting plate 122 and the back cover 130. For example, the third antenna 183 can be fixed to the side of the middle frame 120 away from the display screen 110. The projection of the third antenna 183 along the z-direction on the back cover 130 at least partially overlaps with the projection of the second placement compartment along the z-direction on the back cover 130.

[0156] Exemplarily, the frame 121 can be made directly of metal and serve as an antenna radiator. That is, the frame 121 can be a metal frame, and the metal frame can serve as an antenna radiator. It should be understood that in some embodiments, the second antenna 182 and the third antenna 183 may not be provided, and the metal frame can be directly used as the antenna radiator. That is, the frame 121 can be a metal frame, and the metal frame can serve as the antenna radiator. In other embodiments, the electronic device may also use a metal frame as the antenna radiator while providing the second antenna 182 and / or the third antenna 183, and this application does not limit this.

[0157] In some embodiments, the antenna 180 may include only the first antenna 181, which may be arranged in the corresponding area of ​​the battery compartment. The corresponding area of ​​the battery compartment can be understood as the area where the first antenna 181 overlaps with the projection of the battery compartment along the z-direction. That is, the first antenna 181 may be arranged between the battery 150 and the back cover 130, and the projection of the first antenna 181 on the back cover 130 along the z-direction overlaps with the projection of the battery compartment (or battery 150) on the back cover 130 along the z-direction. It should be understood that, considering the large range of the battery area, by arranging the antenna in the battery area, the antenna arrangement area can be expanded, thereby improving the antenna RF performance of the electronic device.

[0158] It should be noted that, along the first direction (ie, z direction), the distance between the first antenna 181 and the battery 150 is greater than or equal to the first threshold.

[0159] Exemplarily, the first threshold may be in the range of 0.2 mm and above, that is, the antenna clearance threshold may be in the range of 0.2 mm and above. It should be noted that the first threshold is frequency-dependent. For example, when millimeter waves are used, the first threshold may be 0.2 mm.

[0160] It should be noted that a space range of 0.2 mm or greater needs to be maintained between the first antenna 181 and the battery 150 , and the space range can be a cavity or filled with non-metallic materials.

[0161] In some embodiments, an antenna bracket is provided between the first antenna 181 and the back cover 130 . The antenna bracket is connected to the back cover 130 or the middle frame 120 , and is used to support the first antenna 181 .

[0162] It should be understood that the above mainly introduces the differences between the electronic device shown in FIG. 7 and the electronic device shown in FIG. 3 , and the same contents between the two will not be repeated.

[0163] When the electronic device adopts the architecture shown in Figure 7, the antenna 180 can be laid out in most areas of the second storage cavity, that is, the corresponding areas of the first storage compartment, the corresponding areas of the battery compartment, and the corresponding areas of the second storage compartment can all be arranged with the antenna 180, thereby improving the antenna RF performance of the electronic device 100. In addition, the entire middle frame 120 can be designed into a "bow" structure, which can also improve the rigidity of the middle frame 120 and the entire electronic device 100, and enhance product reliability.

[0164] It should be noted that in some other design architectures, the opening of the battery compartment may face the back cover 130, the opening of the first placement compartment may face the display screen 110, and the opening of the second placement compartment may face the back cover 130; or, the opening of the battery compartment may face the back cover 130, the opening of the first placement compartment may face the back cover 130, and the opening of the second placement compartment may face the display screen 110; or, the openings of the first placement compartment, the second placement compartment and the battery compartment may all face the display screen 110; or, the openings of the first placement compartment, the second placement compartment and the battery compartment may all face the back cover 130, and this application does not limit this.

[0165] Figure 8 is a schematic cross-sectional view of another electronic device 200 provided in an embodiment of the present application. The primary difference between the electronic device 200 shown in Figure 8 and the electronic device 100 shown in Figure 3 lies in the different placement of the first antenna 181. In the electronic device 200 shown in Figure 8 , instead of a separate first antenna 181, a metal middle frame forms the antenna radiator. This will be described in detail below with reference to Figure 8.

[0166] As shown in Figure 8, the electronic device 200 may include a display screen 110, a middle frame 120, a back cover 130 and a battery 150, wherein the middle frame 120 is located between the display screen 110 and the back cover 130, the middle frame 120 includes a connecting plate 122 and a frame 121 arranged around the connecting plate 122, and the connecting plate 122 is provided with a battery compartment, which is used to place the battery 150.

[0167] Among them, the first part of the connecting plate 122 (denoted as 1222) can be made of metal, the first part 1222 of the connecting plate 122 is an antenna radiator, and the projection of the first part 1222 of the connecting plate 122 on the back cover 130 along the first direction at least partially overlaps with the projection of the battery 150 on the back cover 130 along the first direction. The first direction (i.e., the z direction) is the thickness direction of the electronic device 200.

[0168] It should be understood that the present application can set the connecting plate 122 corresponding to the battery 150 to be made of metal material, so that the connecting plate 122 made of metal material can directly serve as an antenna radiator without the need to set up a separate antenna.

[0169] Among them, the "connecting plate 122 corresponding to the battery 150" can be understood as the first part 1222 of the connecting plate 122, and the projection of the first part 1222 of the connecting plate 122 along the z direction on the back cover 130 at least partially overlaps with the projection of the battery 150 along the z direction on the back cover 130.

[0170] In the embodiment of the present application, considering that the battery 150 area is relatively large, by deploying the antenna in the battery 150 area, the antenna deployment area can be expanded, thereby increasing the antenna radio frequency performance of the electronic device.

[0171] In some embodiments, along a first direction (ie, z-direction), a distance between the metal connecting plate (ie, the first portion 1222 of the connecting plate 122 ) and the battery 150 is greater than or equal to a first threshold.

[0172] Exemplarily, the first threshold may be in the range of 0.2 mm and above, that is, the antenna clearance threshold may be in the range of 0.2 mm and above. It should be noted that the first threshold is frequency-dependent. For example, when millimeter waves are used, the first threshold may be 0.2 mm.

[0173] It should be noted that a space of 0.2 mm or greater needs to be maintained between the first portion 1222 of the connecting plate 122 and the battery 150 . The space may be a cavity or filled with non-metallic material.

[0174] In some embodiments, as shown in FIG8 , the electronic device 200 may further include a mainboard 161 and a sub-board 162 . A first compartment and a second compartment are provided on the connecting plate 122 , with a battery compartment located between the first and second compartments. The mainboard 161 is placed in the first compartment, and the sub-board 162 is placed in the second compartment. The openings of the first and second compartments are in the same direction, while the opening of the battery compartment is opposite to the openings of the first and second compartments, with the battery compartment opening facing the display screen 110 . Both the openings of the first and second compartments face the rear cover 130 .

[0175] In this embodiment, only the battery compartment opens toward the display screen 110, while the first and second compartments both open toward the back cover 130. This facilitates inspection and repair of malfunctioning electronic components. Furthermore, the entire midframe 120 can be designed in a "bow" shape, thereby increasing the rigidity of the midframe 120 and the entire electronic device, enhancing product reliability.

[0176] In other embodiments, the first and second compartments open in the same direction, while the battery compartment opens in the opposite direction. For example, the battery compartment opens toward the rear cover 130, while the first and second compartments both open toward the display screen 110.

[0177] In other embodiments, the first and second compartments have openings in opposite directions, and the first and battery compartments have openings in the same direction. For example, the battery compartment opens toward the display screen 110, the first compartment opens toward the display screen 110, and the second compartment opens toward the back cover 130.

[0178] In other embodiments, the first and second storage compartments have openings in opposite directions, and the first and battery compartments have openings in the same direction. For example, the battery compartment opens toward the back cover 130, the first storage compartment opens toward the back cover 130, and the second storage compartment opens toward the display screen 110.

[0179] In other embodiments, the openings of the first and second compartments are in opposite directions, and the openings of the second compartment and the battery compartment are in the same direction. For example, the battery compartment opens toward the display screen 110, the first compartment opens toward the back cover 130, and the second compartment opens toward the display screen 110.

[0180] In other embodiments, the openings of the first and second compartments are in opposite directions, and the openings of the second compartment and the battery compartment are in the same direction. For example, the battery compartment opens toward the back cover 130, the first compartment opens toward the display screen 110, and the second compartment opens toward the back cover 130.

[0181] In other embodiments, the opening directions of the first placement compartment, the second placement compartment, and the battery compartment may all be the same. In other words, the openings of the first placement compartment, the second placement compartment, and the battery compartment may all face the display screen 110, or the openings of the first placement compartment, the second placement compartment, and the battery compartment may all face the back cover 130, which is not limited in this application.

[0182] It should be understood that the embodiments of the present application provide design architectures for a variety of electronic devices (such as mobile phones), enrich the layout of devices inside electronic devices, and are applicable to different types of electronic devices.

[0183] Exemplarily, the connecting plate 122 on the middle frame 120 may have a concave-convex structure, and the concave or convex portion may form a first placement compartment, a second placement compartment and a battery compartment. Generally, the first placement compartment and the second placement compartment may be formed in the area surrounded by the connecting plate 122 and the frame 121, and the battery compartment may be located between the first placement compartment and the second placement compartment, and the three areas of the battery compartment, the first placement compartment and the second placement compartment may be separated from each other by the connecting plate 122.

[0184] It should be noted that the above positions of the first placement compartment, the second placement compartment, and the battery compartment are merely exemplary. In other embodiments, the battery compartment may not be disposed between the first placement compartment and the second placement compartment, but may be disposed near the frame 121.

[0185] In some embodiments, the electronic device 200 may further include a second antenna 182 and / or a third antenna 183, wherein the projection of the second antenna 182 along the first direction on the back cover 130 at least partially overlaps with the projection of the first placement bin along the first direction on the back cover 130, and the projection of the third antenna 183 along the first direction on the back cover 130 at least partially overlaps with the projection of the second placement bin along the first direction on the back cover 130.

[0186] Exemplarily, the second antenna 182 can be placed in the first placement compartment, for example, the second antenna 182 can be fixed on the main bracket 171; the third antenna 183 can be placed in the second placement compartment, for example, the third antenna 183 can be fixed on the secondary bracket 172.

[0187] In some embodiments, the second antenna 182 and / or the third antenna 183 can be connected to the mainboard 161 and / or the sub-board 162 via a spring clip; alternatively, the second antenna 182 and / or the third antenna 183 can be bendable (such as an FPC antenna) to connect to the mainboard 161 and / or the sub-board 162. In some embodiments, a hole can be drilled in the first placement compartment, the second placement compartment, or the battery compartment to allow the second antenna 182 and / or the third antenna 183 to pass through the connecting plate 122 of the middle frame 120 and connect to the mainboard 161 located in the first placement compartment and / or the sub-board 162 located in the second placement compartment.

[0188] In some embodiments, the frame 121 is a metal frame 121, and the metal frame 121 serves as an antenna radiator. In this implementation, the frame 121 can serve as a metal antenna radiator.

[0189] It should be understood that in some examples, the electronic device 200 may not be provided with the second antenna 182 and the third antenna 183, but may directly use the metal frame 121 as the antenna radiator. In other examples, the electronic device 200 may be provided with the second antenna 182 and / or the third antenna 183 and use the metal frame 121 as the antenna radiator, and this application is not limited to this.

[0190] It should be noted that in different design architectures of electronic devices (such as FIG. 4 to FIG. 7 ), the first antenna 181 may not be provided, and a metal middle frame as shown in FIG. 8 may be used.

[0191] Fig. 9 is a schematic cross-sectional view of another electronic device 300 provided in an embodiment of the present application. It should be understood that Fig. 9 is mainly an illustrative representation of the position of the speaker 190 in the electronic device.

[0192] As shown in FIG9 , the electronic device 300 may further include a speaker 190 . The speaker 190 may include a first speaker 191 and a second speaker 192 . For example, the first speaker 191 is a top speaker, and the second speaker 192 is a bottom speaker.

[0193] For example, the first speaker 191 can be placed in the first placement compartment, and the second speaker 192 can be placed in the second placement compartment. Both the first placement compartment and the second placement compartment are sealed cavities, as shown in the dotted box in Figure 9. In this example, by setting the first placement compartment and the second placement compartment as sealed cavities, the speakers in the first placement compartment and the second placement compartment will not vibrate strongly when playing music, which can reduce the vibration noise generated by the back cover of the electronic device when playing music.

[0194] It should be understood that in order to configure the first placement chamber and the second placement chamber as a sealed cavity, the gap portion can be sealed using a sealant 201.

[0195] It should be noted that the speaker 190 can be provided in the architecture of the electronic device shown in Figures 3 to 5, 7, and 8. The specific configuration of the speaker 190 can be referred to Figure 9 and will not be elaborated here.

[0196] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
