Technical Field

[0002] The embodiments of the present application relate to the field of terminal technology, and in particular to an electronic device. Background Art

[0003] With the explosive growth of electronic devices such as smartphones and tablets, electronic devices have more and more functions. Different electronic devices are integrated in the shell of the electronic device, such as a central processing unit (CPU), an intelligent algorithm chip, a power management chip (PMIC) or an antenna. An antenna is a device used by an electronic device to receive or transmit electromagnetic wave signals. With the continuous development and iteration of mobile communication technology, the communication requirements required by electronic devices are also getting higher and higher. In related technologies, the structural design of electronic devices is becoming more and more compact and lightweight. However, the frequency bands and types that the antennas of electronic devices are required to cover are increasing. The electronic device includes a middle frame. The middle frame includes at least one frame. The method of setting antenna slots on the frame to form multiple antenna radiators can help meet the design requirements of the antenna radiator. However, there is a relative deviation in the antenna performance of the antenna radiator formed by setting antenna slots on the frame.

[0004] Summary of the Invention

[0005] An embodiment of the present application provides an electronic device that is conducive to enhancing the structural strength of the frame where the antenna gap is opened, while ensuring that the radiator has relatively good antenna performance.

[0006] A first aspect of the present application provides an electronic device, which includes a middle frame, a display screen, a back cover, and a reinforcement body.

[0007] The middle frame includes at least one frame. The frame includes a first radiator and a second radiator. Adjacent ends of the first radiator and the second radiator are spaced apart to form an antenna gap. The first radiator includes a first conductive leg, and the second radiator includes a second conductive leg. Along the thickness direction of the middle frame, the display screen and the back cover are arranged on opposite sides of the middle frame. The reinforcement is located between the display screen and the back cover. The first conductive leg and the second conductive leg are both spaced apart from the reinforcement, and the reinforcement is arranged opposite to the antenna gap. Along the thickness direction of the middle frame, at least one of the first conductive leg and the second conductive leg is located on the side of the reinforcement facing away from the display screen.

[0008] In the electronic device according to the embodiment of the present application, a reinforcement is provided at the antenna slot of the frame to enhance the structural strength of the frame where the antenna slot is provided, thereby reducing the possibility of deviation in the frame's load-bearing capacity and deformation due to a decrease in the frame's structural strength. Furthermore, at least one of the first conductive leg and the second conductive leg is located on the side of the reinforcement facing away from the display screen. A relatively large distance between at least one of the first conductive leg and the display screen facilitates increasing the clearance between at least one of the first conductive leg and the second conductive leg in a confined space, thereby facilitating improved antenna performance of at least one of the first and second radiators. Therefore, in a confined space within an electronic device, the reinforcement, the first conductive leg, and the second conductive leg can be provided simultaneously to enhance the structural strength of the frame where the antenna slot is provided while reducing the possibility of relative deviation in antenna performance of the first or second radiator due to a reduced clearance between the first or second conductive leg, thereby ensuring relatively good antenna performance for at least one of the first and second radiators.

[0009] In a possible implementation, along the thickness direction of the middle frame, the first conductive support leg and the second conductive support leg are both located on a side of the reinforcement body facing away from the display screen.

[0010] The relatively large distance between the first and second conductive legs and the display screen facilitates increasing the clearance between the first and second conductive legs in a confined space, thereby improving the antenna performance of the first and second radiators. Therefore, within the confined space within an electronic device, the reinforcement, first and second conductive legs can be simultaneously provided. This not only enhances the structural strength of the frame where the antenna slot is provided, but also reduces the possibility of relative deviations in antenna performance between the first and second radiators due to the limited clearance between the first and second conductive legs, thereby ensuring relatively good antenna performance for the first and second radiators.

[0011] In a possible implementation, along the thickness direction of the middle frame, an orthographic projection of at least one of the first conductive support leg and the second conductive support leg has an overlapping area with an orthographic projection of the reinforcement.

[0012] The reinforcement can fully utilize the space on the side of at least one of the first conductive support and the second conductive support facing the display screen, so that the structural design of the reinforcement, the first conductive support and the second conductive support is compact, which is conducive to reducing the space occupancy of the reinforcement, the first conductive support and the second conductive support.

[0013] In a possible implementation manner, the orthographic projection of the first conductive support leg and the orthographic projection of the second conductive support leg both have overlapping areas with the orthographic projection of the reinforcement.

[0014] The reinforcement body can fully utilize the space on the side of the first conductive support and the second conductive support facing the display screen, so that the structural design of the reinforcement body, the first conductive support and the second conductive support is compact, and the space occupancy of the reinforcement body, the first conductive support and the second conductive support is reduced.

[0015] In one possible embodiment, at least one of the first conductive leg and the second conductive leg is provided with a contoured surface facing the back cover. The contoured surface has the same shape as the inner wall of the back cover, and a gap is provided between the contoured surface and the inner wall.

[0016] There is a gap between the contoured surface and the inner wall to avoid the first conductive support leg or the second conductive support leg from interfering with the back cover, and also to prevent the back cover from collapsing due to external pressure and squeezing the first conductive support leg or the second conductive support leg.

[0017] In one possible embodiment, the electronic device further includes an insulating filler. The insulating filler connects the reinforcement to the frame. The display includes a flexible connection circuit board having a bend. The flexible connection circuit board is located on a side of the reinforcement facing away from the back cover. A relief groove is provided on a surface of the insulating filler facing the flexible connection circuit board. The relief groove is configured to provide relief for the bend, preventing the bend from being squeezed and damaged by the insulating filler.

[0018] The insulating filler can connect the frame and the reinforcement into a whole, so that the frame, the reinforcement and the insulating filler can form a combination, which can be beneficial to further improve the structural strength of the frame where the antenna gap is opened and improve the impact resistance of the frame.

[0019] In one possible embodiment, a reinforcement is embedded in the insulating filler. The reinforcement forms a bottom wall of a relief groove facing at least a portion of the surface of the flexible interconnect circuit board. The reinforcement avoids the bend and is relatively distant from the bend, preventing the bend from being squeezed and damaged by the reinforcement.

[0020] In a possible implementation manner, the distance between the reinforcement and the first conductive leg is greater than 0.5 mm.

[0021] A relatively large distance can be maintained between the reinforcement and the first conductive leg, thereby reducing the possibility that the reinforcement may adversely affect the electromagnetic wave signal received or transmitted by the first conductive leg.

[0022] In one possible embodiment, the distance between the reinforcement and the second conductive leg is greater than 0.5 mm. A relatively large distance between the reinforcement and the second conductive leg can be maintained, thereby reducing the adverse effects of the reinforcement on the electromagnetic wave signals received or transmitted by the second conductive leg.

[0023] In a possible implementation, the electronic device further includes a conductive connector, wherein one of the first conductive leg and the second conductive leg is electrically connected to the reinforcement through the conductive connector.

[0024] The manner in which the reinforcement is electrically connected to the first conductive support or the reinforcement is electrically connected to the second conductive support, on the one hand, the reinforcement is conducive to enhancing the gap coupling strength between the first radiator and the second radiator, thereby improving the coupling electric field strength between the first radiator and the second radiator, thereby improving the antenna performance; on the other hand, the connection of the reinforcement to the first conductive support or the connection of the reinforcement to the second conductive support is conducive to improving the connection strength and connection stability between the reinforcement and the first radiator or between the reinforcement and the second radiator, thereby improving the structural strength of the combination formed by the reinforcement, the insulating filler and the frame.

[0025] In one possible embodiment, the reinforcement, the conductive connector, and one of the first conductive support leg and the second conductive support leg are an integrally formed structure, which is beneficial to increasing the structural strength of the reinforcement, the conductive connector, and one of the first conductive support leg and the second conductive support leg, and further beneficial to improving the structural strength of the combination formed by the reinforcement, the insulating filler, and the middle frame.

[0026] In a possible embodiment, the conductive connecting member is a welding block. One of the first conductive leg and the second conductive leg is welded to the reinforcement, which helps to reduce processing difficulty and reduce costs.

[0027] In a possible implementation, along the thickness direction of the middle frame, one of the first conductive support leg and the second conductive support leg is located on a side of the reinforcement body facing away from the display screen, and the other is located on a side of the reinforcement body facing the display screen.

[0028] The distance between the first conductive support or the second conductive support located on the side of the reinforcement facing away from the display screen and the display screen is relatively large, which is beneficial for increasing the clearance of the first conductive support or the second conductive support in a small space, thereby improving the antenna performance of the first radiator or the second radiator.

[0029] In a possible implementation manner, the reinforcement body is spaced apart from the middle frame.

[0030] A relatively large distance can be maintained between the reinforcement and the first radiator, as well as between the reinforcement and the second radiator, thereby reducing the possibility that the reinforcement may adversely affect the electromagnetic wave signals received or transmitted by the first radiator and the second radiator.

[0031] In a possible implementation, the first radiator and the second radiator are spaced apart along the length direction of the frame.

[0032] A second aspect of the present application provides an electronic device, which includes a middle frame, a display screen, a back cover, a reinforcement body, and a conductive connector.

[0033] The middle frame includes at least one frame. The frame includes a first radiator and a second radiator. Adjacent ends of the first radiator and the second radiator are spaced apart to form an antenna gap. The first radiator includes a first conductive leg, and the second radiator includes a second conductive leg. Along the thickness direction of the middle frame, the display screen and the back cover are arranged on opposite sides of the middle frame. The reinforcement is located between the display screen and the back cover. The first conductive leg and the second conductive leg are both spaced apart from the reinforcement, and the reinforcement is arranged opposite to the antenna gap. The first conductive leg and the second conductive leg are both spaced apart from the reinforcement. One of the first conductive leg and the second conductive leg is electrically connected to the reinforcement via a conductive connector.

[0034] The manner in which the reinforcement is electrically connected to the first conductive support or the reinforcement is electrically connected to the second conductive support, on the one hand, the reinforcement is conducive to enhancing the gap coupling strength between the first radiator and the second radiator, thereby improving the coupling electric field strength between the first radiator and the second radiator, thereby improving the antenna performance; on the other hand, the connection of the reinforcement to the first conductive support or the connection of the reinforcement to the second conductive support is conducive to improving the connection strength and connection stability between the reinforcement and the first radiator or between the reinforcement and the second radiator, thereby improving the structural strength of the combination formed by the reinforcement, the insulating filler and the frame.

[0035] In a possible implementation, along the thickness direction of the middle frame, the first conductive support leg and the second conductive support leg are both located on a side of the reinforcement body facing the display screen.

[0036] In one possible embodiment, the reinforcement, the conductive connector, and one of the first conductive support leg and the second conductive support leg are an integrally formed structure, which is beneficial to increasing the structural strength of the reinforcement, the conductive connector, and one of the first conductive support leg and the second conductive support leg, and further beneficial to improving the structural strength of the combination formed by the reinforcement, the insulating filler, and the middle frame.

[0037] In a possible embodiment, the conductive connecting member is a welding block. One of the first conductive leg and the second conductive leg is welded to the reinforcement, which helps to reduce processing difficulty and reduce costs.

[0038] In a possible implementation, along the thickness direction of the middle frame, an orthographic projection of at least one of the first conductive support leg and the second conductive support leg has an overlapping area with an orthographic projection of the reinforcement.

[0039] The reinforcement body can fully utilize the space on one side of at least one of the first conductive leg and the second conductive leg, so that the structural design of the reinforcement body, the first conductive leg and the second conductive leg is compact, which is conducive to reducing the space occupancy of the reinforcement body, the first conductive leg and the second conductive leg.

[0040] In a possible implementation, along the thickness direction of the middle frame, the orthographic projection of the reinforcement is a rectangle, so that the shape of the reinforcement is relatively regular, which helps to reduce the difficulty of processing.

[0041] In one possible embodiment, the electronic device further comprises an insulating filler. The insulating filler connects the reinforcement to the frame. The reinforcement comprises a first groove. The opening of the first groove faces the antenna slot, so that the middle portion of the reinforcement is relatively far away from the frame. A relatively large amount of insulating filler can be accommodated between the reinforcement and the frame, which is beneficial to improving the connection strength between the reinforcement, the frame and the insulating filler, thereby improving the structural strength of the combination formed by the reinforcement, the insulating filler and the frame. Alternatively, the opening of the first groove faces away from the antenna slot, so that the middle portion of the reinforcement is relatively far away from the mainboard, so that the middle portion of the reinforcement is less likely to interfere with the mainboard, thereby avoiding the need to avoid the middle portion of the reinforcement and thus reducing the size of the mainboard. The insulating filler covers the first groove. The insulating filler has a first protrusion that matches the shape of the first groove, thereby increasing the connection strength between the insulating filler and the reinforcement, improving the bonding force between the insulating filler and the reinforcement, and further improving the structural strength of the combination formed by the reinforcement, the insulating filler and the frame.

[0042] In one possible embodiment, the electronic device further includes an insulating filler. The insulating filler connects the reinforcement and the frame. The reinforcement includes a first groove. The opening of the first groove faces the antenna slot. A second groove is provided on the bottom wall of the first groove. The insulating filler covers the first groove and the second groove. The insulating filler has a first protrusion that matches the shape of the first groove, and a second protrusion that matches the shape of the second groove, thereby facilitating further increasing the connection strength between the insulating filler and the reinforcement, improving the bonding force between the insulating filler and the reinforcement, and further improving the structural strength of the combination formed by the reinforcement, the insulating filler and the frame.

[0043] In one possible embodiment, the electronic device further includes an insulating filler. The insulating filler connects the reinforcement to the frame. A third groove is provided on the inner wall of at least one of the first radiator and the second radiator. The insulating filler covers the third groove. The insulating filler has a third protrusion that matches the shape of the third groove, thereby further increasing the connection strength between the insulating filler and the reinforcement, improving the bonding force between the insulating filler and the reinforcement, and further improving the structural strength of the combination formed by the reinforcement, the insulating filler, and the frame.

[0044] In one possible embodiment, the reinforcement is arc-shaped. The arc-shaped reinforcement has a smooth and gentle surface transition, a regular shape, is easy to process and manufacture, and has good force balance when bearing stress.

[0045] In a possible implementation, the reinforcement body includes a first reinforcement section and a second reinforcement section that are intersectingly arranged.

[0046] The first reinforcement section and the second reinforcement section are respectively embedded in the insulating filler at different angles, thereby facilitating increasing the connection strength between the insulating filler and the reinforcement and improving the bonding force between the insulating filler and the reinforcement.

[0047] In one possible embodiment, the electronic device further includes a metal midplane and a mainboard. Along the thickness direction of the midframe, the metal midplane and the mainboard are located between the display screen and the back cover. The first radiator and the second radiator are both electrically connected to the metal midplane. The mainboard is disposed on the metal midplane. The mainboard includes a ground terminal. The metal midplane is electrically connected to the ground terminal.

[0048] The first radiator and the second radiator are grounded by using the metal middle plate and the main board, so there is no need to set up additional grounding structures between the first radiator and the main board and between the second radiator and the main board, which is beneficial to reducing the number of components used.

[0091] For example, the electronic components on the motherboard 60 may include, but are not limited to, a central processing unit (CPU), an intelligent algorithm chip, a power management IC (PMIC), or a radio frequency integrated circuit (RFIC). Since the internal space of the electronic device 10 is relatively small, the electronic components can be integrated on the motherboard 60 to fully reduce the size of the motherboard 60 and reduce the space occupied by the motherboard 60.

[0092] The electronic device 10 may further include a battery 70. The battery 70 may be disposed within the housing 30. For example, the battery 70 may be disposed between the back cover 34 and the metal middle plate 50. The battery 70 is a structural component that can convert chemical energy into electrical energy. The battery 70 is used to provide electrical energy to the electronic device 10 to ensure that the electronic device 10 operates normally. For example, the battery 70 may provide electrical energy to the display screen 20 so that the display screen 20 displays image information or completes corresponding operating instructions, or the battery 70 may provide electrical energy to electronic devices to ensure that the electronic devices operate normally. Exemplarily, the battery 70 may be a lithium-ion battery, such as a lithium iron phosphate battery.

[0093] In order to ensure that the electronic device 10 has good communication performance, the middle frame 40 can be used as the radiator of the antenna. The radiator is used to receive or transmit electromagnetic wave signals so that the electronic device 10 can achieve wireless communication functions. The border 40b of the middle frame 40 may include a first radiator and a second radiator. The adjacent ends of the first radiator and the second radiator are spaced apart to form an antenna gap. The first radiator includes a first conductive leg. The second radiator includes a second conductive leg. The first radiator can be electrically connected to the mainboard 60 through the first conductive leg, and the second radiator can be electrically connected to the mainboard 60 through the second conductive leg.

[0094] Figure 5 schematically shows a partial exploded structure of an electronic device 10 according to the related art. Figure 6 schematically shows a partial cross-sectional structure of an electronic device 10 according to the related art. Referring to Figures 5 and 6, in the related art, the antenna slot 40a is provided in the frame 40b, and radiators M are formed on both sides of the antenna slot 40a. This reduces the structural strength of the frame 40b itself. For example, for electronic devices 10 with narrow bezels or curved screens, the provision of the antenna slot 40a in the frame 40b further reduces the structural strength of the frame 40b itself, thereby decreasing the load-bearing capacity of the frame 40b. To address this issue of reduced local structural strength in the electronic device 10, a reinforcement 80 is provided at the location corresponding to the antenna slot 40a to enhance the structural strength of the frame 40b where the antenna slot 40a is provided. The conductive legs M1 of the radiators M are provided on the side of the reinforcement 80 facing the display screen 20. Each radiator M may include one conductive leg M1. The reinforcement 80 and the two conductive legs M1 are spaced apart, that is, the reinforcement 80 and the two conductive legs M1 are not in contact, and the reinforcement 80 and the conductive legs M1 are insulated. Compared with the reinforcement 80, the conductive legs M1 of the radiator M are closer to the display screen 20. The display screen 20 has metal structural parts. For example, the metal structural parts include metal traces in the pixel layer. Alternatively, the metal structural parts include metal traces in the flexible connection circuit board 23. Alternatively, the metal structural parts include a metal back plate 24 provided on the backlight side of the screen body 21. Since the internal space of the electronic device 10 is small and the layout space of the reinforcement 80 and the conductive legs M1 is compact, the minimum distance between the conductive legs M1 and the display screen 20 is relatively small, resulting in the metal structural parts in the display screen 20 having an adverse effect on the electromagnetic wave signals received or transmitted by the radiator M, causing the radiator M to have a relatively deviation in antenna performance.

[0095] It should be noted that the minimum distance between the conductive foot M1 and the display screen 20 refers to the smallest one of the distance between the conductive foot M1 and the pixel layer, the distance between the conductive foot M1 and the bent portion 231 of the flexible connection circuit board 23, and the distance between the conductive foot M1 and the metal backplate 24.

[0096] The electronic device 10 provided in the embodiment of the present application includes a middle frame 40 having a radiator and a reinforcement 80. In the embodiment of the present application, the arrangement of the conductive legs of the radiator and the reinforcement 80 enables the reinforcement 80 to enhance the structural strength of the middle frame 40 where the antenna slot 40a is provided, while also ensuring that the radiator has relatively good antenna performance.

[0097] Figure 7 schematically shows a partial exploded structure of the electronic device 10. Figure 8 schematically shows a partial cross-sectional structure of the electronic device 10. Referring to Figures 7 and 8, the electronic device 10 of the embodiment of the present application includes a display screen 20, a back cover 34, a middle frame 40, and a reinforcement 80.

[0098] The middle frame 40 includes at least one frame 40b. The frame 40b includes a first radiator 41 and a second radiator 42. The adjacent ends of the first and second radiators 41 and 42 are spaced apart to form an antenna slot 40a. For example, the first and second radiators 41 and 42 are spaced apart along the length of the frame 40b. The antenna slot 40a serves to isolate the first and second radiators 41 and 42 on either side, thereby reducing the possibility of mutual interference between the first and second radiators 41 and 42. The first and second radiators 41 and 42 can be used to receive or transmit electromagnetic wave signals, enabling wireless communication for the electronic device 10. The first radiator 41 includes a first conductive leg 411. The first radiator 41 can be electrically connected to external components via the first conductive leg 411. For example, the first radiator 41 can be electrically connected to the motherboard 60 via the first conductive leg 411. For example, the first conductive leg 411 and the motherboard 60 can be electrically connected via a conductive elastic member 500. The second radiator 42 includes a second conductive leg 421. The second radiator 42 can be electrically connected to external related structural components via the second conductive leg 421. For example, the second radiator 42 can be electrically connected to the mainboard 60 via the second conductive leg 421. For example, the second conductive leg 421 and the mainboard 60 can be electrically connected via a conductive elastic member 500. For example, the first conductive leg 411 and the second conductive leg 421 can be positioned near the antenna slot 40a.

[0099] The display screen 20 and the back cover 34 are disposed on the middle frame 40. Along the thickness direction Z of the middle frame 40, the display screen 20 and the back cover 34 are disposed on opposite sides of the middle frame 40. The thickness direction Z of the middle frame 40 can be the same as the thickness direction of the electronic device 10. The reinforcement 80 is located between the display screen 20 and the back cover 34. The first conductive leg 411 and the second conductive leg 421 are both spaced apart from the reinforcement 80, i.e., the reinforcement 80 and the first conductive leg 411 and the second conductive leg 421 do not contact each other, and the reinforcement 80 and the first conductive leg 411 and the second conductive leg 421 are insulated from each other. The reinforcement 80 is disposed opposite the antenna slot 40a. The reinforcement 80 is spaced apart from the middle frame 40, so that the reinforcement 80 and the middle frame 40 are not in direct contact. The reinforcement 80 itself is insulated from the middle frame 40. One end of the reinforcement 80 is located on one side of the antenna slot 40a, and the other end is located on the other side of the antenna slot 40a, so that along the direction perpendicular to the thickness direction Z, the orthographic projection of the reinforcement 80 and the orthographic projection of the antenna slot 40a have an overlapping area.

[0100] Along the thickness direction Z of the middle frame 40, at least one of the first conductive leg 411 and the second conductive leg 421 is located on the side of the reinforcement 80 facing away from the display screen 20. Therefore, relative to the reinforcement 80, at least one of the first conductive leg 411 and the second conductive leg 421 is closer to the back cover 34 and farther away from the display screen 20. The back cover 34 is an insulating structural member, so it does not adversely affect the wireless signals received or transmitted by the first conductive leg 411 and the second conductive leg 421.

[0101] In the electronic device 10 of the embodiment of the present application, a reinforcement 80 is provided at the antenna slot 40a of the frame 40b. The reinforcement 80 enhances the structural strength of the frame 40b where the antenna slot 40a is provided, thereby reducing the possibility of the frame 40b's load-bearing capacity deviation and deformation caused by a decrease in the structural strength of the frame 40b. Furthermore, at least one of the first conductive leg 411 and the second conductive leg 421 is provided on the side of the reinforcement 80 facing away from the display screen 20. The relatively large distance between at least one of the first conductive leg 411 and the second conductive leg 421 and the display screen 20 facilitates increasing the clearance between at least one of the first conductive leg 411 and the second conductive leg 421 in a confined space, thereby facilitating improved antenna performance of at least one of the first radiator 41 and the second radiator 42. Therefore, in the narrow space inside the electronic device 10, a reinforcement 80, a first conductive support 411, and a second conductive support 421 can be set at the same time to enhance the structural strength of the frame 40b where the antenna gap 40a is opened, while reducing the possibility of relative deviation in antenna performance of the first radiator 41 or the second radiator 42 due to the small clearance of the first conductive support 411 or the second conductive support 421, thereby ensuring that at least one of the first radiator 41 and the second radiator 42 has relatively good antenna performance.

[0102] Within the confined space within electronic device 10, reinforcement 80, first conductive leg 411, and second conductive leg 421 are compactly arranged to improve space utilization. Relative to reinforcement 80, first conductive leg 411 and second conductive leg 421 are located relatively far from display screen 20. This increases the minimum distance between first conductive leg 411 and display screen 20, as well as the minimum distance between second conductive leg 421 and display screen 20 within the confined space. This increases the clearance between first conductive leg 411 and second conductive leg 421, thereby enhancing the antenna performance of first radiator 41 and second radiator 42.

[0103] For example, the first conductive leg 411 and the second conductive leg 421 are both positioned corresponding to the bend 231 of the flexible circuit board 23 in the display screen 20. The minimum distance between the first conductive leg 411 and the bend 231 of the flexible circuit board 23 can be 1.2 mm to 1.7 mm, thereby facilitating a relatively large clearance for the first conductive leg 411. For example, the minimum distance between the first conductive leg 411 and the bend 231 of the flexible circuit board 23 can be 1.526 mm. The minimum distance between the second conductive leg 421 and the bend 231 of the flexible circuit board 23 can also be 1.2 mm to 1.7 mm, thereby facilitating a relatively large clearance for the second conductive leg 421. For example, the minimum distance between the second conductive leg 421 and the bend 231 of the flexible circuit board 23 can be 1.526 mm.

[0104] Along the thickness direction Z of the middle frame 40, the orthographic projection of at least one of the first conductive leg 411 and the second conductive leg 421 overlaps with the orthographic projection of the reinforcement 80. The reinforcement 80 fully utilizes the space on the side of at least one of the first conductive leg 411 and the second conductive leg 421 facing the display screen 20, thereby making the structure of the reinforcement 80, the first conductive leg 411, and the second conductive leg 421 compact, thereby reducing the space occupied by the reinforcement 80, the first conductive leg 411, and the second conductive leg 421.

[0105] The first conductive leg 411 is not in direct contact with the reinforcement 80. Accordingly, the second conductive leg 421 is also not in direct contact with the reinforcement 80. For example, in an embodiment where the orthographic projection of the first conductive leg 411 overlaps with the orthographic projection of the reinforcement 80, the first conductive leg 411 is located between the reinforcement 80 and the back cover 34. In an embodiment where the orthographic projection of the second conductive leg 421 overlaps with the orthographic projection of the reinforcement 80, the second conductive leg 421 is located between the reinforcement 80 and the back cover 34. In an embodiment where the orthographic projection of both the first conductive leg 411 and the orthographic projection of the second conductive leg 421 overlap with the orthographic projection of the reinforcement 80, both the first conductive leg 411 and the second conductive leg 421 are located between the reinforcement 80 and the back cover 34.

[0106] In some embodiments, the material of the reinforcement 80 may be different from that of the frame 40b. The reinforcement 80 may be made of a metal material, such as but not limited to aluminum or an aluminum alloy. The reinforcement 80 may also be made of a non-metal material, such as but not limited to ceramic.

[0107] In some implementations, the first radiator 41 and the second radiator 42 on either side of the antenna slot 40a can each form an antenna. The first conductive leg 411 and the second conductive leg 421 are both feeding portions. The first conductive leg 411 and the second conductive leg 421 can be electrically connected to different feeding points on the mainboard 60.

[0108] The motherboard 60 can feed a wireless signal to the first radiator 41 via the corresponding feeding points and the first conductive leg 411, causing the first radiator 41 to radiate the wireless signal and generate an operating frequency band covering the first resonant frequency. The motherboard 60 can also feed a wireless signal to the second radiator 42 via the corresponding feeding points and the second conductive leg 421, causing the second radiator 42 to radiate the wireless signal and generate an operating frequency band covering the second resonant frequency. Therefore, the first radiator 41 and the second radiator 42 can receive or transmit different frequencies.

[0109] In some examples, one of the first radiator 41 and the second radiator 42 on either side of the antenna slot 40a can be a main branch, and the other can be a parasitic branch. For example, the first radiator 41 can be a main branch. The first conductive leg 411 can be a feeder. The second radiator 42 can be a parasitic branch. The second conductive leg 421 can be a tuning unit. The first conductive leg 411 of the first radiator 41 is electrically connected to the feed point of the mainboard 60, so that the mainboard 60 can feed a wireless signal to the first radiator 41, allowing the first radiator 41 to function as an antenna and generate an operating frequency band covering the first resonant frequency. The second conductive leg 421 of the second radiator 42 can be electrically connected to the mainboard 60, making the second radiator 42 a parasitic branch of the first radiator 41. The first radiator 41 and the second radiator 42 can couple with each other to generate an operating frequency band covering the second resonant frequency. In the above solution, the parasitic branch can be coupled with the main branch to stimulate resonance, thereby enhancing the main resonance of the main branch or expanding the bandwidth of the main branch. Exemplarily, both the parasitic branch and the main branch can be used to receive or transmit electromagnetic wave signals.

[0110] For example, the first radiator 41 may support medium-high frequency (MHB). For example, the frequency band of the medium-high frequency range is 1000 MHz to 3000 MHz. The second radiator 42 may support the N78 frequency band. For example, the frequency band of the N78 range is 3300 MHz to 3800 MHz.

[0111] FIG9 is a schematic diagram showing a simulation comparing the radiation efficiency of an antenna in the related art and an antenna in an embodiment of the present application. The antenna is a left-hand antenna mode. Referring to FIG9 , compared to the related art, in the embodiment of the present application, the first radiator 41 can be a main branch. The second radiator 42 can be a parasitic branch. Arranging the first conductive leg 411 and the second conductive leg 421 on the side of the reinforcement 80 facing away from the display screen 20 can increase the radiation efficiency in the mid- and high-frequency bands by 0.3 dB, and the radiation efficiency of the high channel of the N78 band by 0.5 dB, and the bandwidth of both the mid- and high-frequency bands and the N78 band is widened to a certain extent. Therefore, the reinforcement 80, the first conductive leg 411, and the second conductive leg 421 in the embodiment of the present application can be simultaneously arranged inside the electronic device 10, and the arrangement of the reinforcement 80, the first conductive leg 411, and the second conductive leg 421 is conducive to improving antenna performance.

[0112] In some examples, the distance between the reinforcement 80 and the first conductive leg 411 is greater than 0.5 mm. A relatively large distance can be maintained between the reinforcement 80 and the first conductive leg 41, thereby reducing the possibility that the reinforcement 80 will adversely affect the electromagnetic wave signals received or transmitted by the first conductive leg 41. For example, the minimum distance between the reinforcement 80 and the first conductive leg 411 is 0.5 mm.

[0113] The distance between the reinforcement 80 and the second conductive leg 421 is greater than 0.5 mm. Maintaining a relatively large distance between the reinforcement 80 and the second conductive leg 42 reduces the possibility of the reinforcement 80 adversely affecting the electromagnetic wave signals received or transmitted by the second conductive leg 42. For example, the minimum distance between the reinforcement 80 and the second conductive leg 421 is 0.5 mm.

[0114] The distance between the reinforcement 80 and the display screen 20 is greater than 0.25 mm. For example, the minimum distance between the reinforcement 80 and the display screen 20 is 0.25 mm. For example, the distance between the reinforcement 80 and the bent portion 231 of the flexible connection circuit board 23 can be the minimum distance between the reinforcement 80 and the display screen 20. Alternatively, the distance between the reinforcement 80 and the metal back plate 24 can be the minimum distance between the reinforcement 80 and the display screen 20. Alternatively, the distance between the reinforcement 80 and the pixel layer can be the minimum distance between the reinforcement 80 and the display screen 20.

[0115] In some implementations, at least one of the first conductive leg 411 and the second conductive leg 421 is provided with a contoured surface 100 (see FIG8 ) facing the back cover 34. The contoured surface 100 has the same shape as the inner wall of the back cover 34. A gap is provided between the contoured surface 100 and the inner wall to prevent the first conductive leg 411 or the second conductive leg 421 from interfering with the back cover 34. This also prevents the back cover 34 from collapsing under external pressure, which could squeeze the first conductive leg 411 or the second conductive leg 421.

[0116] Exemplarily, the first conductive leg 411 and the second conductive leg 421 each include a contoured surface 100 facing the back cover 34 .

[0117] Exemplarily, the inner wall of the back cover 34 facing the contoured surface 100 is in an arc shape. Accordingly, the contoured surface 100 is also in an arc shape.

[0118] In some achievable embodiments, the electronic device 10 further includes an insulating filler 90. The insulating filler 90 connects the reinforcement 80 and the frame 40b. For example, the reinforcement 80 is embedded in the insulating filler 90. The insulating filler 90 can connect the frame 40b and the reinforcement 80 as a whole, so that the frame 40b, the reinforcement 80 and the insulating filler 90 can form a combination, which can be beneficial to further improve the structural strength of the frame 40b where the antenna gap 40a is opened, and improve the impact resistance of the frame 40b. Exemplarily, a portion of the insulating filler 90 can be filled in the antenna gap 40a. The insulating filler 90 can insulate the first radiator 41 and the second radiator 42 on both sides of the antenna gap 40a, thereby ensuring the continuity of the frame 40b, which is beneficial to improve the structural strength of the frame 40b. At the same time, the insulating filler 90 will not affect the performance of the antenna.

[0119] For example, the insulating filler 90 may be an insulating glue. The frame 40b, the reinforcement 80 and the insulating filler 90 may be combined into a body by injection molding.

[0120] In some possible implementations, the flexible connection circuit board 23 is located on a side of the reinforcement 80 away from the back cover 34. One end of the flexible connection circuit board 23 is connected to the screen body 21, and the other end is electrically connected to the driver chip 22 disposed on the backlight side of the screen body 21. A bend 231 is formed in the middle portion of the flexible connection circuit board 23. The reinforcement 80 is disposed corresponding to the bend 231. An avoidance groove 200 is provided on the surface of the insulating filling body 90 facing the flexible connection circuit board 23. The avoidance groove 200 avoids the bend 231 to prevent the bend 231 from being squeezed and damaged by the insulating filling body 80. The avoidance groove 200 has an opening facing the bend 231.

[0121] At least a portion of the bent portion 231 can be located within the relief groove 200, thereby improving space utilization in a confined space. The shape of the relief groove 200 wall facing the bent portion 231 can match the shape of the bent portion 231. For example, if the bent portion 231 is arcuate, the shape of the relief groove 200 wall facing the bent portion 231 can also be arcuate. A gap exists between the relief groove 200 wall facing the bent portion 231 and the bent portion 231.

[0122] The reinforcement 80 forms a bottom wall of the groove 200 on at least a portion of the surface facing the flexible circuit board 23. The reinforcement 80 can avoid the bent portion 231 and is relatively far away from the bent portion 231 to prevent the bent portion 231 from being squeezed and damaged by the reinforcement 80.

[0123] For example, before installing the insulating filler 90, the reinforcement 80 is connected to the frame 40b via a metal connector to secure the position of the reinforcement 80. The insulating filler 90 is then installed. After the reinforcement 80, the insulating filler 90, and the frame 40b are joined, the metal connector is removed, along with a portion of the insulating filler 90 and a portion of the reinforcement 80, thereby ultimately forming the avoidance groove 200.

[0124] In some implementations, the orthographic projections of the first conductive leg 411 and the second conductive leg 421 overlap with the orthographic projection of the reinforcement 80. The first conductive leg 411 and the second conductive leg 421 are both located between the reinforcement 80 and the back cover 34.

[0125] In some examples, Figure 10 schematically illustrates a partial structure of an electronic device 10. As shown in Figure 10 , along the thickness direction Z of the middle frame 40, the orthographic projection of the reinforcement 80 can be rectangular, for example, a long rectangle. The relatively regular shape of the reinforcement 80 helps reduce processing difficulty. The first conductive leg 411 and the second conductive leg 421 are spaced apart along the length of the reinforcement 80. Along the width of the reinforcement 80, at least one of the first conductive leg 411 and the second conductive leg 421 extends beyond the reinforcement 80.

[0126] In some examples, FIG11 schematically illustrates a partial structure of electronic device 10. As shown in FIG11 , reinforcement 80 includes a first groove 80a. The opening of first groove 80a faces away from antenna slot 40a. The middle portion of reinforcement 80 is closer to antenna slot 40a. The middle portion of reinforcement 80 is relatively far from mainboard 60, making it less likely to interfere with mainboard 60. This prevents the mainboard 60 from being reduced in size due to the need for the mainboard 60 to avoid the middle portion of reinforcement 80.

[0127] FIG12 schematically shows a partial structure of the electronic device 10. FIG13 schematically shows a partial cross-sectional structure of the electronic device 10. Referring to FIG12 and FIG13, the opening of the first groove 80a faces the antenna slot 40a, so that the middle portion of the reinforcement 80 is relatively far away from the frame 40b. A relatively large amount of insulating filler 90 can be accommodated between the reinforcement 80 and the frame 40b, which is beneficial to improving the connection strength between the reinforcement 80, the frame 40b, and the insulating filler 90, thereby improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90, and the frame 40b. The middle portion of the reinforcement 80 is far away from the antenna slot 40a. The insulating filler 90 covers the first groove 80a, so that the first groove 80a is buried in the insulating filler 90. The insulating filler 90 has a first protrusion 90a that matches the shape of the first groove 80a, thereby increasing the connection strength between the insulating filler 90 and the reinforcement 80, improving the bonding force between the insulating filler 90 and the reinforcement 80, and further improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90, and the frame 40b. For example, the first groove 80a extends through the reinforcement 80 along the thickness direction Z of the middle frame 40.

[0128] For example, the reinforcement 80 may be arc-shaped. The arc-shaped reinforcement 80 has a smooth and gentle surface transition, a regular shape, is easy to process and manufacture, and has good force balance when bearing stress. For example, the reinforcement 80 may be arc-shaped.

[0129] For example, Figure 14 schematically illustrates the partial structure of the electronic device 10. As shown in Figure 14, the reinforcement 80 includes a first reinforcement section 81 and a second reinforcement section 82 arranged to intersect. The first reinforcement section 81 and the second reinforcement section 82 are embedded in the insulating filler 90 at different angles, thereby increasing the connection strength between the insulating filler 90 and the reinforcement 80 and improving the bonding force between the insulating filler 90 and the reinforcement 80. The first reinforcement section 81 and the second reinforcement section 82 can both be straight sections, giving the reinforcement 80 an overall "V" shape. For example, the angle between the first reinforcement section 81 and the second reinforcement section 82 can be greater than or equal to 90°. The opening of the first groove 80a faces away from the antenna slot 40a. For example, the first reinforcement section 81 corresponds to the first conductive leg 411, and the second reinforcement section 82 corresponds to the second conductive leg 421. Alternatively, Figure 15 schematically illustrates the partial structure of the electronic device 10. As shown in FIG. 15 , the opening of the first groove 80 a faces the antenna slot 40 a .

[0130] For example, FIG16 schematically shows a partial structure of the electronic device 10. FIG17 schematically shows a partial cross-sectional structure of the electronic device 10. As shown in FIG16 and FIG17 , the opening of the first groove 80a faces the antenna slot 40a. A second groove 80b is provided on the bottom wall of the first groove 80a. The first groove 80a is connected to the second groove 80b. An insulating filler 90 covers the first groove 80a and the second groove 80b. The insulating filler 90 covers the first groove 80a and the second groove 80b, so that the first groove 80a and the second groove 80b are buried within the insulating filler 90. The insulating filler 90 has a first protrusion 90a that matches the shape of the first groove 80a and a second protrusion 90b that matches the shape of the second groove 80b. This helps further increase the connection strength between the insulating filler 90 and the reinforcement 80, improves the bonding force between the insulating filler 90 and the reinforcement 80, and further helps further improve the structural strength of the combination formed by the reinforcement 80, the insulating filler 90, and the frame 40b. For example, along the thickness direction Z of the middle frame 40, the second groove 80b can penetrate the reinforcement body 80. For example, the number of the second grooves 80b is at least two. The number of the second protrusions 90b is equal to the number of the second grooves 80b.

[0131] Furthermore, a third groove 300 may be provided on the inner wall of at least one of the first radiator 41 and the second radiator 42. Specifically, the third groove 300 may be provided on the inner wall of the first radiator 41, or the inner wall of the second radiator 42, or both. The third groove 300 faces the reinforcement 80. For example, the second groove 80b and the third groove 300 may be staggered. The insulating filler 90 covers the third groove 300. The insulating filler 90 covers the first groove 80a, the second groove 80b, and the third groove 300, such that the first groove 80a, the second groove 80b, and the third groove 300 are embedded within the insulating filler 90. The insulating filler 90 also has a third protrusion 90c whose shape matches the third groove 300, which is beneficial to further increase the connection strength between the insulating filler 90 and the reinforcement 80, improve the bonding force between the insulating filler 90 and the reinforcement 80, and further help to further improve the structural strength of the combination formed by the reinforcement 80, the insulating filler 90 and the frame 40b.

[0132] In some implementations, the electronic device 10 further includes a metal midplate 50 and a mainboard 60. Along the thickness direction Z of the middle frame 40, the metal midplate 50 and the mainboard 60 are both located between the display screen 20 and the back cover 34. The first radiator 41 and the second radiator 42 are both electrically connected to the metal midplate 50. The mainboard 60 can be disposed on the metal midplate 50. The mainboard 60 includes a ground terminal. The metal midplate 50 is electrically connected to the ground terminal to ground the first radiator 41 and the second radiator 42.

[0133] The first radiator 41 and the second radiator 42 are grounded by using the metal middle plate 50 and the main board 60, so there is no need to set additional grounding structures between the first radiator 41 and the main board 60 and between the second radiator 42 and the main board 60, which is beneficial to reducing the number of components used.

[0134] In some implementations, FIG18 schematically illustrates a partial cross-sectional view of the electronic device 10. FIG19 schematically illustrates a partial structure of the electronic device 10. Referring to FIG18 and FIG19 , along the thickness direction Z of the middle frame 40, the first conductive leg 411 and the second conductive leg 421 are both located on the side of the reinforcement 80 facing away from the display 20. The reinforcement 80 is positioned adjacent to the display 20.

[0135] In some examples, the electronic device 10 further includes a conductive connector 400. The reinforcement 80 is a conductor. One of the first conductive leg 411 and the second conductive leg 421 is connected to the reinforcement 80 via the conductive connector 400. Of the first radiator 41 and the second radiator 42 on either side of the antenna slot 40a, one can be a main branch, and the other can be a parasitic branch. The reinforcement 80 is connected to the first radiator 41 or the second radiator 42, which is a main branch.

[0136] For example, the first radiator 41 can be a main branch. The first conductive leg 411 can be a feeding portion. The second radiator 42 can be a parasitic branch. The second conductive leg 421 can be a tuning portion. The first conductive leg 411 of the first radiator 41 is electrically connected to the feeding point of the mainboard 60, so that the mainboard 60 can feed a wireless signal to the first radiator 41, so that the first radiator 41 acts as an antenna and generates an operating frequency band covering the first resonant frequency. The second conductive leg 421 of the second radiator 42 can be electrically connected to the mainboard 60, so that the second radiator 42 acts as a parasitic branch of the first radiator 41, so that the first radiator 41 and the second radiator 42 can couple with each other to generate an operating frequency band covering the second resonant frequency.

[0137] For example, the first radiator 41 may support medium-high frequency (MHB). For example, the frequency band of the medium-high frequency range is 1000 MHz to 3000 MHz. The second radiator 42 may support the N78 frequency band. For example, the frequency band of the N78 range is 3300 MHz to 3800 MHz.

[0138] In the embodiment of the present application, the manner in which the reinforcement 80 is electrically connected to the first conductive leg 411 or the reinforcement 80 is electrically connected to the second conductive leg 421, on the one hand, the reinforcement 80 is conducive to enhancing the gap coupling strength between the first radiator 41 and the second radiator 42, thereby improving the coupling electric field strength between the first radiator 41 and the second radiator 42, thereby improving the antenna performance; on the other hand, the connection of the reinforcement 80 to the first conductive leg 411 or the connection of the reinforcement 80 to the second conductive leg 421 is conducive to improving the connection strength and connection stability between the reinforcement 80 and the first radiator 41 or between the reinforcement 80 and the second radiator 42, thereby improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90 and the frame 40b.

[0139] The reinforcement 80, the conductive connector 400, and one of the first conductive leg 411 and the second conductive leg 421 are an integrally formed structure, which is beneficial to increasing the structural strength of the reinforcement 80, the conductive connector 400, and one of the first conductive leg 411 and the second conductive leg 421, and further beneficial to improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90 and the middle frame 40.

[0140] In some examples, the first conductive leg 411 is connected to the reinforcement 80 via a conductive connector 400. The reinforcement 80, the conductive connector 400, and the first conductive leg 411 can be made of the same material. The reinforcement 80, the conductive connector 400, and the first conductive leg 411 are integrally formed, thereby increasing the structural strength of the reinforcement 80, the conductive connector 400, and the first conductive leg 411, and further increasing the structural strength of the combination formed by the reinforcement 80, the insulating filler 90, and the frame 40b. For example, the reinforcement 80, the conductive connector 400, and the first conductive leg 411 can be made of, but not limited to, aluminum or an aluminum alloy.

[0141] In some examples, the second conductive leg 421 is connected to the reinforcement 80 via a conductive connector 400. The reinforcement 80, the conductive connector 400, and the second conductive leg 421 can be made of the same material. The reinforcement 80, the conductive connector 400, and the second conductive leg 421 are integrally formed, thereby increasing the structural strength of the reinforcement 80, the conductive connector 400, and the second conductive leg 421, and further increasing the structural strength of the combination formed by the reinforcement 80, the insulating filler 90, and the frame 40b. For example, the reinforcement 80, the conductive connector 400, and the second conductive leg 421 can be made of, but not limited to, aluminum or an aluminum alloy.

[0142] In some examples, the conductive connector 400 is a welding block. One of the first conductive leg 411 and the second conductive leg 421 is welded to the reinforcement 80. After the welding operation is completed between the first conductive leg 411 and the second conductive leg 421 and the reinforcement 80, the resulting welding block is the conductive connector 400. For example, the material of the reinforcement 80 can be the same as that of the frame 40b. For example, the material of the reinforcement 80 and the frame 40b can both be aluminum or an aluminum alloy.

[0143] The embodiment of the present application also provides an electronic device 10. The electronic device 10 in this embodiment has the same structure as that in the above-mentioned electronic device 10, and will not be repeated here. In the electronic device 10, the reinforcement 80 is arranged opposite to the antenna gap 40a. The reinforcement 80 is spaced apart from the frame 40b, and the reinforcement 80 is insulated from the frame 40b. The first conductive support 411 and the second conductive support 421 are both spaced apart from the reinforcement 80, and the reinforcement 80 and the first conductive support 411 and the reinforcement 80 and the second conductive support 421 are insulated. The electronic device 10 also includes a conductive connector 400. One of the first conductive support 411 and the second conductive support 421 is electrically connected to the reinforcement 80 via the conductive connector 400.

[0144] For example, one of the first radiator 41 and the second radiator 42 on both sides of the antenna slot 40a can be a main branch and the other can be a parasitic branch. The reinforcement 80 is connected to the first radiator 41 or the second radiator 42 as a main branch.

[0145] For example, the first radiator 41 can be a main branch. The first conductive leg 411 can be a feeder. The second radiator 42 can be a parasitic branch. The second conductive leg 421 can be a tuning unit. The first conductive leg 411 of the first radiator 41 is electrically connected to the feed point of the mainboard 60, so that the mainboard 60 can feed a wireless signal to the first radiator 41, allowing the first radiator 41 to function as an antenna and generate an operating frequency band covering the first resonant frequency. The second conductive leg 421 of the second radiator 42 can be electrically connected to the mainboard 60, so that the second radiator 42 functions as a parasitic branch of the first radiator 41. This allows the first radiator 41 and the second radiator 42 to couple with each other and generate an operating frequency band covering the second resonant frequency. For example, the first radiator 41 can support medium-high frequency (MHB). For example, the medium-high frequency band ranges from 1000 MHz to 3000 MHz. The second radiator 42 can support the N78 band. For example, the N78 band ranges from 3300 MHz to 3800 MHz.

[0146] In the electronic device 10 of the embodiment of the present application, the manner in which the reinforcement 80 is electrically connected to the first conductive leg 411 or the second conductive leg 421, on the one hand, the reinforcement 80 is conducive to enhancing the gap coupling strength between the first radiator 41 and the second radiator 42, thereby improving the coupling electric field strength between the first radiator 41 and the second radiator 42 on both sides of the antenna slot 40a, thereby improving the antenna performance; on the other hand, the connection of the reinforcement 80 to the first conductive leg 411 or the connection of the reinforcement 80 to the second conductive leg 421 is conducive to improving the connection strength and connection stability between the reinforcement 80 and the first radiator 41 or between the reinforcement 80 and the second radiator 42, thereby improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90 and the frame 40b.

[0147] In some implementations, as shown in Figures 18 and 19 , along the thickness direction Z of the middle frame 40, the first conductive leg 411 and the second conductive leg 421 are both located on the side of the reinforcement 80 facing away from the display screen 20. The reinforcement 80 is positioned adjacent to the display screen 20. The electronic device 10 also includes a conductive connector 400. The reinforcement 80 is an electrical conductor. One of the first conductive leg 411 and the second conductive leg 421 is connected to the reinforcement 80 via the conductive connector 400.

[0148] In some implementations, FIG20 schematically illustrates a partial cross-sectional view of the electronic device 10. FIG21 schematically illustrates a partial exploded view of the electronic device 10. Referring to FIG20 and FIG21 , along the thickness direction Z of the middle frame 40, the first conductive leg 411 and the second conductive leg 421 are both located on the side of the reinforcement 80 facing the display 20. The reinforcement 80 is positioned near the back cover 34. Relative to the reinforcement 80, the first conductive leg 411 and the second conductive leg 421 are both closer to the display 20 and farther away from the back cover 34.

[0149] In some examples, Figure 22 schematically illustrates a partial structure of an electronic device 10. As shown in Figure 22 , along the thickness direction Z of the middle frame 40, the orthographic projection of the reinforcement 80 can be rectangular, for example, a long rectangle. The relatively regular shape of the reinforcement 80 helps reduce manufacturing difficulty. The reinforcement 80 is connected to the first conductive leg 411 via a conductive connector 400.

[0150] In some examples, FIG23 schematically shows a partial structure of the electronic device 10. As shown in FIG23, the reinforcement 80 includes a first groove 80a. The first groove 80a faces the antenna slot 40a. The reinforcement 80 can be arc-shaped. The arc-shaped reinforcement 80 has a smooth and gentle surface transition, a regular shape, is easy to process and manufacture, and has good force balance when bearing stress. For example, the reinforcement 80 can be an arc. Alternatively, FIG24 schematically shows a partial structure of the electronic device 10. As shown in FIG24, the reinforcement 80 includes a first reinforcement section 81 and a second reinforcement section 82 arranged to intersect. The first reinforcement section 81 and the second reinforcement section 82 are respectively embedded in the insulating filler 90 at different angles, which is conducive to increasing the connection strength between the insulating filler 90 and the reinforcement 80 and improving the bonding force between the insulating filler 90 and the reinforcement 80. The first reinforcement section 81 and the second reinforcement section 82 can both be straight sections, so that the reinforcement body 80 is in a V shape. The first reinforcement section 81 and the first conductive leg 411 are connected via a conductive connector 400 .

[0151] In some examples, the opening of the first groove 80a can be disposed away from the antenna slot 40a. The reinforcement 80 can be arc-shaped. Alternatively, the reinforcement 80 includes a first reinforcement section 81 and a second reinforcement section 82 disposed so as to intersect with each other.

[0152] FIG25 is a schematic diagram of a simulation comparing the radiation efficiency of an antenna of the related art and an antenna of an embodiment of the present application. The antenna is a left-hand antenna mode. The first radiator 41 is a main branch, and the second radiator 42 is a parasitic branch. In the embodiment of the present application, the first conductive leg 411 and the second conductive leg 421 are both arranged on the side of the reinforcement 80 facing the display screen 20, and the reinforcement 80 is electrically connected to the first conductive leg 411, which can improve the radiation efficiency of medium and high frequencies by 0.4 dB. Therefore, the arrangement of the reinforcement 80, the first conductive leg 411, and the second conductive leg 421 can also help improve the structural strength of the antenna gap 40a, while also helping to improve antenna performance.

[0153] In some examples, along the thickness direction Z of the middle frame 40, the orthographic projection of at least one of the first conductive leg 411 and the second conductive leg 421 overlaps with the orthographic projection of the reinforcement 80. Along the thickness direction Z of the middle frame 40, the reinforcement 80 can fully utilize the space on one side of at least one of the first conductive leg 41 and the second conductive leg 42, thereby making the structure of the reinforcement 80, the first conductive leg 41, and the second conductive leg 42 compact, thereby reducing the space occupied by the reinforcement 80, the first conductive leg 41, and the second conductive leg 42.

[0154] For example, in an embodiment where the orthographic projection of the first conductive leg 411 overlaps with the orthographic projection of the reinforcement 80, the first conductive leg 411 is located between the reinforcement 80 and the display screen 20. In an embodiment where the orthographic projection of the second conductive leg 421 overlaps with the orthographic projection of the reinforcement 80, the second conductive leg 421 is located between the reinforcement 80 and the display screen 20. In an embodiment where the orthographic projection of both the first conductive leg 411 and the orthographic projection of the second conductive leg 421 overlap with the orthographic projection of the reinforcement 80, both the first conductive leg 411 and the second conductive leg 421 are located between the reinforcement 80 and the display screen 20.

[0155] In some implementations, the first conductive leg 411 is connected to the reinforcement 80 via a conductive connector 400. The reinforcement 80, the conductive connector 400, and the first conductive leg 411 are an integrally formed structure.

[0156] In some implementations, the second conductive leg 421 is connected to the reinforcement 80 via a conductive connector 400. The reinforcement 80, the conductive connector 400, and the second conductive leg 421 are an integrally formed structure.

[0157] In some implementations, the conductive connector 400 is a welding block, and one of the first conductive leg 411 and the second conductive leg 421 is welded to the reinforcement 80 .

The orthographic projection of at least one of the first conductive leg 411 and the second conductive leg 421 has an overlapping area with the orthographic projection of the reinforcement 80 .

[0159] In some examples, the reinforcement 80 includes a first reinforcement segment 81, a second reinforcement segment 82, and a third reinforcement segment 83.

The second conductive leg 421 is located on the side of the second reinforcing section 82 facing away from the display screen 20. The third reinforcing section 83 passes between the first conductive leg 411 and the second conductive leg 421. Alternatively, in other examples, the first conductive leg 411 may be located on the side of the first reinforcing section 81 facing away from the display screen 20, and the second conductive leg 421 may be located on the side of the second reinforcing section 82 facing the display screen 20.

[0162] For example, the second reinforcement section 82 is intersected with the third reinforcement section 83. For example, the angle between the second reinforcement section 82 and the third reinforcement section 83 may be greater than or equal to 90°.

[0163] In some examples, FIG28 schematically illustrates a partially exploded structure of electronic device 10. As shown in FIG28 , first conductive leg 411 is electrically connected to first reinforcement section 81. Illustratively, reinforcement 80 is a conductor. Electronic device 10 also includes a conductive connector 400. First conductive leg 411 is connected to first reinforcement section 81 via conductive connector 400. Illustratively, first radiator 41 can be a primary branch, while second radiator 42 can be a parasitic branch.

[0164] The manner in which the reinforcement 80 is electrically connected to the first conductive leg 411 is, on the one hand, beneficial for enhancing the gap coupling strength between the first radiator 41 and the second radiator 42, thereby improving the coupling electric field strength between the first radiator 41 and the second radiator 42, and thus beneficial for improving the antenna performance; on the other hand, the connection between the reinforcement 80 and the first conductive leg 411 is beneficial for improving the connection strength and connection stability between the reinforcement 80 and the first radiator 41, thereby beneficial for improving the structural strength of the combination formed by the reinforcement 80, the insulating filler 90 and the frame 40b.
