Figure 1 is one of the structural block diagrams of an electronic device according to an embodiment. Referring to Figure 1 (Figure 1 is only a simple schematic diagram and is not limiting), in this embodiment, the electronic device includes a middle frame 10, a conductive sliding cover 20, a flexible screen 30 and a shell 40, and the middle frame 10 and the conductive sliding cover 20 can be arranged on the shell 40, and the flexible screen 30 can be arranged on the middle frame 10 and the conductive sliding cover 20.

The middle frame 10 and the conductive sliding cover 20 can slide relative to each other, and while supporting the flexible screen 30, the flexible screen 30 can be driven to switch between the expanded state and the contracted state, so that the electronic device is in the corresponding expanded state or contracted state. The housing 40 can have a certain structural strength, which can be used to protect the middle frame 10, the conductive sliding cover 20 and the flexible screen 30.

When the flexible screen 30 is in the unfolded state, it can have a larger display area to display more images to the user. When the flexible screen 30 is in the collapsed state, as shown in the second structural block diagram of the electronic device in FIG. 2, part of the flexible screen 30 The area is received between the conductive sliding cover 20 and the housing 40 , and is disposed opposite to and spaced from the housing 40 .

FIG3 is a third structural block diagram of an electronic device according to an embodiment. Referring to FIG3 (FIG3 shows the electronic device in a retracted state, and the conductive element is not shown in FIG3), in this embodiment, the electronic device includes a conductive sliding cover 20, a middle frame 10, an antenna unit 50 and a conductive element.

A conductive sliding cover 20; a middle frame 10, which is arranged opposite to the conductive sliding cover 20 and spaced apart, and includes a first conductive middle plate 110 and a second conductive middle plate 120 which are slidably connected, and the second conductive middle plate 120 is connected to the conductive sliding cover 20, wherein the conductive sliding cover 20 slides relative to the first conductive middle plate 110 along with the second conductive middle plate 120, so that the electronic device is in an expanded state or a retracted state; an antenna unit 50, which is arranged on the first conductive middle plate 110; a conductive element, which is connected to the conductive sliding cover 20, and when the electronic device is in a retracted state, the conductive element is arranged adjacent to the antenna unit 50, so as to reduce the conductive sliding cover 20 from absorbing the electromagnetic energy radiated by the antenna unit 50.

Among them, the middle frame 10 and the conductive sliding cover 20 are arranged opposite to each other and spaced apart. Both the middle frame 10 and the conductive sliding cover 20 have a certain structural strength and can form a support structure that can slide relatively. The surfaces of the two opposite sides of the support structure can be used to set the flexible screen 30 in the electronic device, and the support structure can support the flexible screen 30; and, during the relative sliding process of the middle frame 10 and the conductive sliding cover 20, the flexible screen 30 can be driven to switch between the expanded state and the retracted state, so that the electronic device is in the corresponding expanded state or retracted state. Optionally, the middle frame 10 and the conductive sliding cover 20 can also be jointly surrounded to form a receiving space, which can be used to install the electronic devices required in the electronic device, such as the motherboard, battery, and sensor, etc. Optionally, both the middle frame 10 and the conductive sliding cover 20 can be metal.

Among them, the first conductive middle plate 110 and the second conductive middle plate 120 are connected in a sliding manner. When a larger display area is required, the first conductive middle plate 110 and the second conductive middle plate 120 move away from each other by sliding, and the flexible screen 30 and the electronic device are in an unfolded state; when a larger display area is not required, the first conductive middle plate 110 and the second conductive middle plate 120 move closer to each other by sliding, and the flexible screen 30 and the electronic device are in a retracted state. Optionally, the side of the first conductive middle plate 110 that is slidably connected to the second conductive middle plate 120 can be in a first comb shape, and the side of the second conductive middle plate 120 that is slidably connected to the first conductive middle plate 110 can be in a second comb shape that matches the first comb shape, so that the first comb-shaped first conductive middle plate 110 and the second comb-shaped second conductive middle plate 120 can be completely attached and fastened when approaching each other, thereby improving the supporting capacity. It can be understood that the opposite sides of the first conductive middle plate 110 and the second conductive middle plate 120 can also present other shapes, which are not further limited in this embodiment. Optionally, the reciprocating sliding of the second conductive middle plate 120 relative to the first conductive middle plate 110 can be achieved by the user applying an external force, or by providing an independent driving structure in the accommodating space, such as a motor, to provide a driving force.

Among them, the conductive sliding cover 20 is connected to the second conductive middle plate 120. When the second conductive middle plate 120 slides in the direction away from the first conductive middle plate 110, the conductive sliding cover 20 slides relative to the first conductive middle plate 110 and moves away from the first conductive middle plate 110 under the guidance of the second conductive middle plate 120; when the second conductive middle plate 120 slides in the direction approaching the first conductive middle plate 110, the conductive sliding cover 20 slides relative to the first conductive middle plate 110 and moves closer to the first conductive middle plate 110 under the guidance of the second conductive middle plate 120. Optionally, the conductive sliding cover 20 and the second conductive middle plate 120 can be directly connected. When directly connected, part of the conductive sliding cover 20 and part of the second conductive middle plate 120 can be in a bent state relative to other parts, so that most of the conductive sliding cover 20 and most of the second conductive middle plate 120 are arranged opposite to each other and spaced apart; or they can be connected to each other through a conductive connecting piece, which can support the conductive sliding cover 20 and the second conductive middle plate 120, so that the conductive sliding cover 20 and the second conductive middle plate 120 are arranged opposite to each other and spaced apart.

The antenna unit 50 is disposed on the first conductive middle plate 110 for radiating electromagnetic waves. Optionally, the antenna unit 50 is disposed on a side of the first conductive middle plate 110, and the side of the first conductive middle plate 110 is parallel to the direction in which the second conductive middle plate 120 slides relative to the first conductive middle plate 110 (the X-axis direction in the figure).

The conductive element is connected to the conductive sliding cover 20. When the electronic device is in the retracted state, the projection of the conductive element on the plane where the antenna unit 50 is located and the distance between the antenna unit 50 are within a preset range, so that the conductive element and the antenna unit 50 are arranged adjacent to each other. As a result, the conductive element destroys the original resonant structure formed by the middle frame 10 and the conductive sliding cover 20, suppresses the resonant mode of the resonant structure, and reduces the absorption of electromagnetic energy radiated by the conductive sliding cover 20 to the antenna unit 50. 1. As shown in FIG1, when the electronic device is in the retracted state, there is a certain gap between the conductive sliding cover 20 and the middle frame 10 where the antenna unit 50 is located. Therefore, the middle frame 10, the conductive sliding cover 20, and the connecting area between the middle frame 10 and the conductive sliding cover 20 form a resonant structure that easily absorbs electromagnetic waves of a certain frequency band of the antenna unit 50, resulting in a reduction in the electromagnetic energy that the antenna unit 50 can radiate into the free space, thereby reducing the reduction in antenna efficiency; in addition, an accommodation space is formed inside the resonant structure, and some circuit boards, metal devices, etc. may be arranged inside, so that the radiation performance of the resonant structure is weak, and the resonant structure may further absorb more electromagnetic energy. Optionally, the conductive element is used to destroy the resonant mode of the resonant structure formed by the conductive sliding cover 20 and the middle frame 10 to reduce the electromagnetic energy of the antenna unit 50 absorbed by the conductive sliding cover 20.

As shown in FIG. 4 , in the resonant structure, the projection area of the conductive sliding cover 20 on the middle frame 10 is smaller than the sum of the areas of the first conductive middle plate 110 and the second conductive middle plate 120 of the middle frame 10, so that the conductive sliding cover 20 is equivalent to the antenna body, and the middle frame 10 is equivalent to the ground plate of the conductive sliding cover 20. Before the conductive element is set, the length of the two sides of the conductive sliding cover 20 parallel to the relative sliding direction affects the resonant frequency of the conductive sliding cover 20. At the same time, the current distribution on the two sides of the conductive sliding cover 20 parallel to the relative sliding direction will also present a sinusoidal distribution of 0.5 cycles, 1 cycle, 1.5 cycles, etc. according to the different resonant frequencies. FIG. 4 takes 1.5 cycles as an example for illustration. After the conductive element is set, the conductive element destroys the resonant mode of the resonant structure formed by the conductive sliding cover 20 and the middle frame 10, thereby reducing the amount of electromagnetic energy radiated by the antenna unit 50 absorbed by the resonant structure, weakening the influence of clutter, and improving the efficiency of the antenna unit 50, thereby improving the user experience.

The electronic device provided in this embodiment includes a conductive sliding cover 20, a middle frame 10, an antenna unit 50 and a conductive element; the middle frame 10 is opposite to the conductive sliding cover 20 and is arranged at an interval, including a first conductive middle plate 110 and a second conductive middle plate 120 that are slidably connected, the conductive sliding cover 20 is connected to the second conductive middle plate 120 and slides relative to the first conductive middle plate 110 with the second conductive middle plate 120, so that the electronic device is in an expanded state or a retracted state; the antenna unit 50 is arranged on the first conductive middle plate 110; the conductive element is connected to the conductive sliding cover 20, and when the electronic device is in a retracted state, the conductive element is arranged adjacent to the antenna unit 50 to reduce the conductive sliding cover 20 from absorbing the electromagnetic energy radiated by the antenna unit 50, thereby reducing the influence of clutter, improving the efficiency of the antenna unit 50, and thus improving the user experience.

FIG5 is a fifth structural block diagram of an electronic device of an embodiment. Referring to FIG5 , in this embodiment, the antenna unit 50 is disposed on the side of the first conductive middle plate 110, and the side of the first conductive middle plate 110 is parallel to the direction in which the second conductive middle plate 120 and the first conductive middle plate 110 slide relative to each other; wherein the conductive element is a conductive accessory 60 disposed on the side of the conductive sliding cover 20 close to the antenna unit 50, and the conductive accessory 60 is spaced apart from the middle frame 10.

Among them, the antenna unit 50 is arranged on the side of the first conductive middle plate 110, and the side of the first conductive middle plate 110 is parallel to the direction in which the second conductive middle plate 120 slides relative to the first conductive middle plate 110, so that when the conductive sliding cover 20 slides away from the first conductive middle plate 110 with the second conductive middle plate 120, the conductive sliding cover 20 is away from the antenna unit 50. At this time, the conductive sliding cover 20 has a small effect on the antenna efficiency of the antenna unit 50; when the conductive sliding cover 20 slides close to the first conductive middle plate 110 with the second conductive middle plate 120, the conductive sliding cover 20 gradually approaches the antenna unit 50, and the effect of the conductive sliding cover 20 on the antenna efficiency of the antenna unit 50 gradually increases.

Among them, the conductive element is a conductive accessory 60 arranged on the side of the conductive sliding cover 20 close to the antenna unit 50. The conductive accessory 60 is spaced apart from the middle frame 10. When the electronic device is in a retracted state, the conductive accessory 60 is arranged adjacent to the antenna unit 50. The conductive accessory 60 will physically destroy the resonant structure formed by the conductive sliding cover 20 and the middle frame 10, suppress the resonance between the conductive sliding cover 20 and the antenna unit 50, thereby reducing the intensity of the current generated by the resonance of the conductive sliding cover 20 and the antenna unit 50, and reducing the electromagnetic wave energy radiated to the antenna unit 50.

Optionally, the conductive accessory 60 extends in the direction of relative sliding, which is equivalent to extending the length of the side of the conductive sliding cover 20 and extending the current path of the conductive sliding cover 20 near the antenna unit 50, thereby further changing the resonant frequency of the resonant structure, thereby moving its influence on the antenna unit 50 outside the frequency band of the nearby antenna. Optionally, the dimension of the conductive accessory 60 extending in the direction of relative sliding is within the range of 1/8 wavelength-1/2 wavelength, and the wavelength is the wavelength of the center frequency point when the antenna unit 50 radiates. For example, the radiation frequency band of the antenna unit 50 is 1427MHz-2690MHz, and the corresponding center frequency point wavelength is 2058.5MHz, which is conducive to further avoiding the occurrence of the resonant structure and the antenna unit 50. The conductive sliding cover 20 is used to generate a resonance, and at the same time, it is beneficial to suppress the transmission of electromagnetic waves radiated by the antenna formed by the conductive sliding cover 20, and improve the isolation effect between the antenna unit 50 and the conductive sliding cover 20. It can be understood that along the relative sliding direction, the conductive accessory 60 can extend in a plane parallel to the conductive sliding cover 20, or in a direction perpendicular to the sliding cover, and the aforementioned technical effect can be obtained as long as the extension direction is parallel to the relative sliding direction.

Optionally, when the electronic device is in the retracted state, the projection of the conductive accessory 60 on the plane where the antenna unit 50 is located and the distance from the antenna unit 50 are within a preset range, so that the conductive accessory 60 is adjacent to the antenna unit 50. The preset range can be adjusted according to the radiation parameters of the antenna unit 50, for example, the preset range can be that the distance from the antenna unit 50 is within the range of 0-20 mm.

In one embodiment, please continue to refer to FIG. 5. In this embodiment, the conductive accessory 60 includes: a conductive decorative part 610 and a conductive connecting part 620. The conductive connecting part 620 is disposed on the side of the conductive sliding cover 20 close to the antenna unit 50 and is respectively connected to the conductive decorative part 610 and the conductive sliding cover 20; the conductive decorative part 610 is spaced apart from the conductive sliding cover 20 and the middle frame 10; wherein, when the conductive sliding cover 20 slides, the conductive connecting part 620 drives the conductive decorative part 610 to slide relative to the first conductive middle plate 110.

Among them, the conductive decorative part 610 is an existing accessory in the electronic device, and when it is not connected to the conductive sliding cover 20 through the conductive connecting part 620, it has the function of decoration and beauty; when the conductive decorative part 610 and the conductive connecting part 620 constitute a conductive element, the existing accessories in the electronic device are fully utilized, and on the basis of not needing to introduce other components that affect the appearance of the electronic device, the conductive sliding cover 20 can also reduce the absorption of electromagnetic energy radiated by the antenna unit 50 when the electronic device is in a retracted state, thereby helping to improve the utilization rate of accessories, while reducing costs and improving the radiation performance of the antenna unit 50, and improving the user experience. Optionally, both the conductive decorative part 610 and the conductive connecting part 620 can be metal, so that they have a metallic luster on the basis of being able to achieve conductivity, which can improve the aesthetic effect.

Optionally, as shown in FIG5 , the conductive connector 620 may be perpendicular to the conductive decorative member 610 and the conductive sliding cover 20, respectively, the plane where the conductive decorative member 610 is located may be perpendicular to the plane where the conductive sliding cover 20 is located, the plane where the conductive decorative member 610 is located may completely cover the conductive connector 620, and the plane of the conductive decorative member 610 may extend in the direction of relative sliding. Optionally, the dimension of the plane of the conductive decorative member 610 extending in the direction of relative sliding is within the range of 1/8 wavelength to 1/2 wavelength, where the wavelength is the wavelength of the center frequency point when the antenna unit 50 radiates, thereby further avoiding the resonance between the resonant structure and the antenna unit 50, and at the same time, suppressing the transmission of the electromagnetic wave radiated by the antenna formed by the conductive sliding cover 20, and improving the isolation effect between the antenna unit 50 and the conductive sliding cover 20.

It is understood that the plane of the conductive decorative member 610 and the conductive connecting member 620 may both extend in the direction of relative sliding, and the extension size may be within the range of 1/8 wavelength to 1/2 wavelength. In other embodiments, the conductive accessory 60 may also only include the conductive connecting member 620, and the conductive connecting member 620 extends in the direction of relative sliding, and the extension size may be within the range of 1/8 wavelength to 1/2 wavelength.

Please refer to Figures 6 to 8 for assistance. Figure 6 is a product structure diagram of the electronic device in a retracted state after the conductive accessory 60 is set in an embodiment based on Figure 5. Figure 7 is a diagram of the antenna radiation efficiency of the electronic device in both the expanded state and the retracted state before the conductive accessory 60 is set. As shown in Figure 7, affected by the resonant structure and the actual internal friction material, the radiation efficiency of the antenna in the retracted state is reduced by 2-3dB in the Wi-Fi 5G frequency band. Figure 8 is a diagram of the antenna radiation efficiency of the electronic device shown in Figure 5 in both the expanded state and the retracted state. As shown in Figure 8, after the conductive accessory 60 is set, the electromagnetic energy absorbed by the antenna unit 50 is reduced, and the radiation efficiency of the antenna unit 50 in the Wi-Fi 5G frequency band is improved by about 1.5dB. This shows that the radiation efficiency of the antenna unit 50 is indeed improved due to the destruction of the resonant structure.

Please refer to Figures 9 and 10 for assistance. Figure 9 shows the actual current distribution inside the conductive slide cover 20 of an embodiment when the electronic device with the same product structure is in a retracted state before the conductive accessory 60 is set. Figure 10 shows the current distribution inside the conductive slide cover 20 with the same product structure at the same scale when the electronic device is in a retracted state after the conductive accessory 60 is set. It can be seen that after the conductive accessory 60 is set, the current on the inner wall of the conductive slide cover 20 is significantly weakened, which means that the field strength inside the resonant structure is significantly weakened, indicating that the electromagnetic energy of the antenna unit 50 entering the resonant structure is reduced, thereby improving the radiation efficiency of the antenna unit 50, and obtaining the antenna radiation efficiency result as shown in Figure 7.

FIG11 is a sixth structural block diagram of an electronic device according to an embodiment. Referring to FIG11 , in this embodiment, the middle frame 10 further includes a frame decoration 130 disposed on the first conductive middle plate 110 , and the electronic device further includes: a housing 40 .

The shell 40 includes a back cover 410 arranged opposite to the conductive sliding cover 20 and a frame 420 connected to the back cover 410. The shell 40 can slide relative to the first conductive middle plate 110 along with the conductive sliding cover 20; wherein the conductive decorative piece 610 is formed on the frame 420; when the electronic device is in a retracted state, the shell 40 and the frame decorative piece 130 together form a shell to accommodate the middle frame 10 and the conductive sliding cover 20.

The frame 420 is connected to the conductive sliding cover 20 so as to slide with the conductive sliding cover 20 relative to the first conductive middle plate 110; the frame 420 can be connected to the conductive sliding cover 20 through the conductive decorative member 610 and the conductive connecting member 620, or can be connected to the conductive sliding cover 20 through other parts of the conductive decorative member 610. For example, the frame 420 can be fixedly connected to the conductive sliding cover 20 by bolting, welding, and clamping.

Among them, the back cover 410 is arranged opposite to the conductive sliding cover 20 and the back cover 410 is connected to the frame 420, so that the back cover 410 slides relative to the first conductive middle plate 110 along with the frame 420 and the conductive sliding cover 20. Optionally, the back cover 410 and the conductive sliding cover 20 are arranged opposite to each other and spaced apart, and a gap can be formed between the back cover 410 and the conductive sliding cover 20. When the flexible screen 30 is in a retracted state, at least part of the non-display area is retracted to between the back cover 410 and the conductive sliding cover 20. Further optionally, the spacing between the back cover 410 and the conductive sliding cover 20 can be greater than the thickness of the flexible screen 30, thereby providing an escape space for the movement of the flexible screen 30, and preventing the flexible screen 30 from rubbing against the back cover 410 during the movement, causing the flexible screen 30 to be worn. It can be understood that the back cover 410 and the frame 420 can be an integral structure, or can be relatively independent components, and the two can be fixedly connected by bonding, welding, and clamping, etc., which is not limited in this embodiment.

As shown in FIG. 11 , the middle frame 10 further includes a border decoration 130 disposed on the first conductive middle plate 110, and the shell 40 can slide relative to the first conductive middle plate 110 along with the conductive sliding cover 20. When the electronic device is in a retracted state, the border decoration 130 can form a shell together with the shell 40 to accommodate the middle frame 10 and the conductive sliding cover 20, so as to protect the middle frame 10 and the conductive sliding cover 20 and the flexible screen 30 disposed on the middle frame 10 and the conductive sliding cover 20.

On the one hand, the conductive decorative piece 610 is formed on the frame 420. As a decorative piece on the frame 420, the conductive decorative piece 610 not only has the function of decoration and beauty, but also can drive the hook cover to slide with the conductive sliding cover 20 relative to the first conductive middle plate 110 during the sliding process of the first conductive middle plate 110 and the second conductive middle plate 120. When the electronic device is in a retracted state, it can form a complete shell with the frame decorative piece 130 and other components on the frame 420 and the back cover 410, so as to accommodate and protect the middle frame 10, the conductive sliding cover 20 and the flexible screen 30. On the other hand, the conductive decorative piece 610 and the conductive connecting piece 620 constitute a conductive element, which makes full use of the existing accessories in the electronic device. Without introducing other components that affect the appearance of the electronic device, it can reduce the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20 when the electronic device is in a retracted state, thereby helping to improve the radiation performance of the antenna unit 50 while reducing costs and improving the user experience.

FIG. 12 is a seventh structural block diagram of an electronic device according to an embodiment. Referring to FIG. 12 , in this embodiment, the conductive element includes at least one grounding member 70 connected to the middle frame 10 and the conductive sliding cover 20 respectively.

The conductive element is at least one grounding member 70 connected to the middle frame 10 and the conductive slide cover 20 respectively, so that the middle frame 10 and the conductive slide cover 20 are arranged on the same ground, thereby destroying the resonant mode of the resonant structure to reduce the electromagnetic energy of the antenna unit 50 absorbed by the conductive slide cover 20. In addition, the grounding setting of the conductive slide cover 20 and the middle frame 10 can also suppress the cavity mode between the conductive slide cover 20 and the middle frame 10, reduce the repeated oscillation of clutter in the non-radiation mode, and further improve the radiation performance of the antenna unit 50.

Optionally, the antenna unit 50 is disposed on the side of the first conductive middle plate 110; the grounding member 70 is respectively connected to the side of the conductive sliding cover 20 close to the antenna unit 50 and the side of the target conductive middle plate, and at least covers part of the gap between the conductive sliding cover 20 and the middle frame 10; the target conductive middle plate includes at least one of the first conductive middle plate 110 and the second conductive middle plate 120. As shown in the eighth structural block diagram of an electronic device of an embodiment shown in FIG13 (FIG. 13 only shows the first conductive middle plate 110, the second conductive middle plate 120 and the part opposite to the conductive sliding cover 20, and the grounding member 70), when the grounding member 70 only covers part of the gap, the grounding member 70 can realize the common ground connection between the conductive sliding cover 20 and the target conductive middle plate, thereby destroying the resonant mode of the resonant structure to reduce the electromagnetic energy of the antenna unit 50 absorbed by the conductive sliding cover 20; further, As shown in the ninth structural block diagram of an electronic device of an embodiment shown in FIG14 (FIG14 only shows the first conductive middle plate 110, the part of the second conductive middle plate 120 opposite to the conductive sliding cover 20, and the grounding member 70), the grounding member 70 completely covers the gap, and the gap between the conductive sliding cover 20 and the middle frame 10 close to the antenna unit 50 is filled, which is equivalent to the conductive sliding cover 20 and the middle frame 10 on this side forming a closed conductive member, completely destroying the resonant mode of the resonant structure, thereby being more conducive to improving the radiation performance of the antenna unit 50. It can be understood that when the gap is filled, the grounding member 70 can be a sheet-like metal plate, which can be fixedly connected to the conductive sliding cover 20 and the second conductive middle plate 120, and slidably connected to the first conductive middle plate 110, or other implementations can be used, which are not further limited in this embodiment.

Optionally, the grounding member 70 is a conductive spring sheet, the fixed end of which is disposed on the conductive sliding cover 20, the free end of which is in contact with the target conductive middle plate, and the conductive spring sheet slides along with the conductive sliding cover 20; or, the fixed end of the conductive spring sheet is disposed on the target conductive middle plate, the free end of the conductive spring sheet is in contact with the conductive sliding cover 20, and the target conductive middle plate includes one of the first conductive middle plate 110 and the second conductive middle plate 120. By setting the grounding member 70 as a conductive spring sheet, the contact position of the free end of the conductive spring sheet can be flexibly adjusted, so that the free end of the grounding member 70 is not limited to a fixed position, which is conducive to improving the flexibility of the grounding position of the grounding member 70 and the flexibility of the relative sliding between the conductive sliding cover 20 and the middle frame 10.

Optionally, the grounding member 70 is a short-circuit probe, and two ends of the short-circuit probe are respectively arranged on the conductive sliding cover 20 and the second conductive middle plate 120. When the target conductive middle plate is the second conductive middle plate 120, since the conductive sliding cover 20 and the second conductive middle plate 120 are relatively stationary, a short-circuit probe can be arranged to be fixedly connected to the conductive sliding cover 20 and the second conductive middle plate 120, respectively, so as to improve the stability of the grounding member 70 and avoid the open circuit.

FIG15 is a tenth structural block diagram of an electronic device according to an embodiment. Referring to FIG15 , in this embodiment, the electronic device includes: a conductive sliding cover 20 , a middle frame 10 , an antenna unit 50 , and an opening 80 is provided on the conductive sliding cover 20 .

A conductive sliding cover 20; a middle frame 10, arranged opposite to the conductive sliding cover 20, comprising a first conductive middle plate 110 and a second conductive middle plate 120 which are slidably connected, the second conductive middle plate 120 being connected to the conductive sliding cover 20, wherein the conductive sliding cover 20 slides with the second conductive middle plate 120 relative to the first conductive middle plate 110, so that the electronic device is in an expanded state or a retracted state; an antenna unit 50, arranged on the first conductive middle plate 110; wherein the conductive sliding cover 20 is provided with an opening 80, and when the electronic device is in a retracted state, the opening 80 is arranged adjacent to the antenna unit 50, so as to reduce the conductive sliding cover 20 from absorbing electromagnetic energy radiated by the antenna unit 50.

The conductive sliding cover 20 , the middle frame 10 , and the antenna unit 50 may refer to the relevant descriptions in the above embodiments, and will not be further elaborated here.

The conductive sliding cover 20 is provided with an opening 80. When the electronic device is in the retracted state, the opening 80 is arranged adjacent to the antenna unit 50. Thus, the opening 80 destroys the original resonance structure formed by the middle frame 10 and the conductive sliding cover 20, suppresses the resonance mode of the resonance structure, and reduces the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20. Specifically, the conductive sliding cover 20 is provided with an opening 80. The existence of the opening 80 is equivalent to extending the length of the side of the conductive sliding cover 20. Thus, the opening 80 extends the current path of the conductive sliding cover 20, thereby changing the resonance frequency of the resonance structure, thereby moving its influence on the antenna unit 50 to outside the frequency band of the nearby antenna, and reducing the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20.

Optionally, the antenna unit 50 is arranged on the side of the first conductive middle plate 110, and the side of the first conductive middle plate 110 is parallel to the direction of relative sliding between the second conductive middle plate 120 and the first conductive middle plate 110; the opening 80 is arranged on the side of the conductive sliding cover 20 close to the antenna unit 50 and extends along the direction of relative sliding.

The opening 80 is disposed on the side of the conductive sliding cover 20 close to the antenna unit 50. When the electronic device is in the retracted state, the opening 80 is disposed adjacent to the antenna unit 50. The opening 80 will physically destroy the conductive sliding cover 20 and the antenna unit 50. The resonant structure formed by the frame 10 suppresses the resonance between the conductive sliding cover 20 and the antenna unit 50, thereby reducing the intensity of the current generated by the resonance between the conductive sliding cover 20 and the antenna unit 50, and reducing the electromagnetic wave energy radiated to the antenna unit 50. It can be understood that the opening 80 is provided on the side of the conductive sliding cover 20 close to the antenna unit 50, and can be at the position shown in FIG. 15, or at the position shown in the structural block diagram of an electronic device of an embodiment shown in FIG. 16, and can be adjusted according to the position of the antenna unit 50. The shape of the opening 80 is not limited, for example, it can be a rectangular opening 80, or it can be other shapes, and the present application does not make further restrictions on this.

The extension of the opening 80 in the direction of relative sliding is equivalent to extending the length of the side of the conductive sliding cover 20, and extending the current path of the conductive sliding cover 20 near the antenna unit 50, thereby further changing the resonant frequency of the resonant structure, thereby moving its influence on the antenna unit 50 outside the frequency band of the nearby antenna. Optionally, the extension size of the opening 80 in the direction of relative sliding is within the range of 1/8 wavelength-1/2 wavelength, and the wavelength is the wavelength of the center frequency point when the antenna unit 50 radiates. For example, the radiation frequency band of the antenna unit 50 is 1427MHz-2690MHz, and the corresponding center frequency point wavelength is 2058.5MHz, which is conducive to further avoiding the resonance of the resonant structure and the antenna unit 50, and at the same time, it is conducive to suppressing the transmission of electromagnetic waves radiated by the antenna formed by the conductive sliding cover 20, and improving the isolation effect between the antenna unit 50 and the conductive sliding cover 20.

Optionally, when the electronic device is in the retracted state, the projection of the opening 80 on the plane where the antenna unit 50 is located and the distance from the antenna unit 50 are within a preset range, so that the conductive accessory 60 is adjacent to the antenna unit 50. The preset range can be adjusted according to the radiation parameters of the antenna unit 50, for example, the preset range can be that the distance from the antenna unit 50 is within the range of 0-20 mm.

The electronic device provided in this embodiment can physically destroy the resonant structure formed by the conductive slide 20 and the middle frame 10 by setting the opening 80 on the conductive slide 20, thereby suppressing the resonance between the conductive slide 20 and the antenna unit 50, thereby reducing the intensity of the current generated by the resonance between the conductive slide 20 and the antenna unit 50, and reducing the electromagnetic wave energy radiated to the antenna unit 50.
