For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.

Fig. 1 is a block diagram of an electronic device according to an embodiment, and referring to fig. 1 (fig. 1 is only a simplified schematic diagram, and is not limited to this), in this embodiment, the electronic device includes a middle frame 10, a conductive sliding cover 20, a flexible screen 30, and a housing 40, where the middle frame 10 and the conductive sliding cover 20 may be disposed on the housing 40, and the flexible screen 30 may be disposed on the middle frame 10 and the conductive sliding cover 20.

The middle frame 10 and the conductive sliding cover 20 can slide relatively, and when the flexible screen 30 is supported, the flexible screen 30 can be driven to switch between an expanded state and a contracted state, so that the electronic device is in the corresponding expanded state or the contracted state. The housing 40 may have a certain structural strength, which may 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 pictures for the user. When the flexible screen 30 is in the retracted state, as shown in the second block diagram of the electronic device shown in fig. 2, a partial area of the flexible screen 30 is received between the conductive sliding cover 20 and the housing 40, and is opposite to and spaced apart from the housing 40.

Fig. 3 is a third structural block diagram of an electronic device according to an embodiment, referring to fig. 3 (fig. 3 shows the electronic device in a contracted state, and fig. 3 does not show a conductive element), 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; the middle frame 10 is opposite to the conductive sliding cover 20 and arranged at an interval, and includes a first conductive middle plate 110 and a second conductive middle plate 120 which are connected in a sliding manner, the second conductive middle plate 120 is connected with the conductive sliding cover 20, wherein the conductive sliding cover 20 slides along 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 contracted state; an antenna unit 50 disposed on the first conductive middle plate 110; and the conductive element is connected with the conductive sliding cover 20, and when the electronic device is in a contracted state, the conductive element is arranged adjacent to the antenna unit 50 so as to reduce the absorption of the conductive sliding cover 20 on the electromagnetic energy radiated by the antenna unit 50.

The middle frame 10 and the conductive sliding cover 20 are arranged opposite to each other at intervals, both the middle frame 10 and the conductive sliding cover 20 have certain structural strength, and can form a support structure capable of sliding relatively, the surfaces of two opposite sides of the support structure can be used for arranging the flexible screen 30 in the electronic device, and the support structure can support the flexible screen 30; moreover, in 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 contracted state, so that the electronic device is in the corresponding expanded state or the contracted state. Optionally, the middle frame 10 and the conductive sliding cover 20 may also be enclosed together to form an accommodating space, and the accommodating space may be used to install electronic devices required in the electronic device, such as a main board, a battery, a sensor, and the like. Alternatively, both the middle frame 10 and the conductive sliding cover 20 may be metal.

The first middle conductive plate 110 and the second middle conductive plate 120 are connected in a sliding manner, and when a larger display area is needed, the first middle conductive plate 110 and the second middle conductive plate 120 are far away from each other through sliding, and the flexible screen 30 and the electronic device are in an unfolded state; when a large display area is not needed, the first conductive middle plate 110 and the second conductive middle plate 120 approach each other by sliding, and the flexible screen 30 and the electronic device are in a contracted state. Optionally, one side of the first conductive middle plate 110 slidably connected to the second conductive middle plate 120 may be in a first comb shape, and one side of the second conductive middle plate 120 slidably connected to the first conductive middle plate 110 may be in a second comb shape matched to the first comb shape, so that the first conductive middle plate 110 in the first comb shape and the second conductive middle plate 120 in the second comb shape may be completely attached and fastened when approaching each other, thereby improving the supporting capability. It is understood that the opposite side edges of the first conductive middle plate 110 and the second conductive middle plate 120 may also take other shapes, and the embodiment is not further limited. Alternatively, the second middle conductive plate 120 may slide back and forth relative to the first middle conductive plate 110 by applying an external force by a user, or by providing a separate driving structure in the accommodating space, such as a motor or the like, to provide a driving force.

The conductive sliding cover 20 is connected to the second middle conductive plate 120, and when the second middle conductive plate 120 slides away from the first middle conductive plate 110, the conductive sliding cover 20 slides along with the second middle conductive plate 120 relative to the first middle conductive plate 110 and away from the first middle conductive plate 110 under the guiding action of the second middle conductive plate 120; when the second middle conductive plate 120 slides toward the direction close to the first middle conductive plate 110, the sliding conductive cover 20 slides along with the second middle conductive plate 120 relative to the first middle conductive plate 110 and approaches to the first middle conductive plate 110 under the guiding action of the second middle conductive plate 120. Optionally, the conductive sliding cover 20 and the second conductive middle plate 120 may be directly connected, and when the conductive sliding cover 20 and the second conductive middle plate 120 are directly connected, a part of the conductive sliding cover 20 and a part of the second conductive middle plate 120 may be in a bent state relative to other parts, so that a majority of the conductive sliding cover 20 and a majority of the second conductive middle plate 120 are arranged relatively and at an interval; or are connected to each other through a conductive connector, 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 at an interval.

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

The conductive element is connected with the conductive sliding cover 20, and when the electronic device is in a contracted 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 adjacently arranged, and therefore, the conductive element destroys the original resonance structure formed by the middle frame 10 and the conductive sliding cover 20, and inhibits the resonance mode of the resonance structure, so that the absorption of the conductive sliding cover 20 on the electromagnetic energy radiated by the antenna unit 50 is reduced. Specifically, please refer to fig. 1 with continuing assistance, as shown in fig. 1, when the electronic device is in a contracted state, a certain gap exists between the conductive sliding cover 20 and the middle frame 10 where the antenna unit 50 is located, and thus, the middle frame 10, the conductive sliding cover 20, and the area connected 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, which results in a reduction in electromagnetic energy that the antenna unit 50 can radiate into a free space, thereby reducing a reduction in antenna efficiency; in addition, the inside accommodation space that forms of resonant structure, inside probably sets up some circuit boards, metal material's device etc for resonant structure's radiation performance is weaker, also can further make resonant structure absorb more electromagnetic energy. Optionally, the conductive element is used to break 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 fourth block diagram of the electronic device according to the embodiment, in the resonant structure, the projected 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 an antenna body, and the middle frame 10 is equivalent to a ground plate of the conductive sliding cover 20. Before the conductive element is not arranged, the lengths of the two sides of the conductive sliding cover 20 parallel to the relative sliding direction affect the resonant frequency of the conductive sliding cover 20, and meanwhile, the current distribution on the two sides of the conductive sliding cover 20 parallel to the relative sliding direction also presents sinusoidal distribution of 0.5 cycle, 1 cycle, 1.5 cycle \8230thatand the like according to the difference of the resonant frequency. Fig. 4 illustrates an example of a 1.5 cycle. After the conductive element is arranged, the conductive element destroys the resonant mode of the resonant structure formed by the conductive sliding cover 20 and the middle frame 10, so that the amount of electromagnetic energy radiated by the antenna unit 50 and absorbed by the inside of the resonant structure is reduced, clutter influence is weakened, the efficiency of the antenna unit 50 is improved, and user experience is improved.

The electronic device provided by the 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, and includes a first conductive middle plate 110 and a second conductive middle plate 120 which are connected in a sliding manner, the conductive sliding cover 20 is connected with the second conductive middle plate 120 and slides along 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 contracted state; an antenna unit 50 disposed on the first conductive middle plate 110; the conductive element is connected with the conductive sliding cover 20, and when the electronic device is in a contraction state, the conductive element is arranged adjacent to the antenna unit 50, so that the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20 is reduced, the influence of clutter is weakened, the efficiency of the antenna unit 50 is improved, and the user experience is improved.

Fig. 5 is a block diagram illustrating an electronic device according to an embodiment, and referring to fig. 5, in this embodiment, an antenna unit 50 is disposed on a side edge of a first middle conductive plate 110, and the side edge of the first middle conductive plate 110 is parallel to a sliding direction of a second middle conductive plate 120 and the first middle conductive plate 110; the conductive element is a conductive fitting 60 disposed on a side of the conductive sliding cover 20 close to the antenna unit 50, and the conductive fitting 60 is spaced apart from the middle frame 10.

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

The conductive element is a conductive fitting 60 disposed on the side of the conductive sliding cover 20 close to the antenna unit 50, the conductive fitting 60 is disposed at an interval with the middle frame 10, when the electronic device is in a contracted state, the conductive fitting 60 is disposed adjacent to the antenna unit 50, the conductive fitting 60 will physically destroy the resonance structure formed by the conductive sliding cover 20 and the middle frame 10, and suppress resonance between the conductive sliding cover 20 and the antenna unit 50, thereby reducing the intensity of current generated by resonance between the conductive sliding cover 20 and the antenna unit 50, and reducing the electromagnetic wave energy when radiating to the antenna unit 50.

Optionally, the conductive fitting 60 extends in the direction of relative sliding, which is equivalent to extending the length of the side of the conductive sliding lid 20 and extending the current path of the conductive sliding lid 20 near the side of the antenna unit 50, thereby further changing the resonant frequency of the resonant structure, thereby moving its influence on the antenna unit 50 out of the frequency band of the nearby antenna. Optionally, the size of the conductive fitting 60 extending in the direction of relative sliding is in a range of 1/8 wavelength to 1/2 wavelength, the wavelength is a central frequency point wavelength when the antenna unit 50 radiates, for example, a radiation frequency band of the antenna unit 50 is 1427MHz to 2690MHz, and the central frequency point wavelength is 2058.5MHz, so as to further avoid resonance between the resonance structure and the antenna unit 50, and at the same time, to suppress transmission of electromagnetic waves radiated by an antenna formed by the conductive sliding cover 20, and to improve an isolation effect between the antenna unit 50 and the conductive sliding cover 20. It will be appreciated that the conductive fitting 60 may extend in a direction parallel to the plane of the conductive sliding cover 20 and may also extend in a direction perpendicular to the sliding cover, and the aforementioned technical effects can be obtained only by extending in a direction parallel to the relative sliding direction.

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

In an embodiment, with continued reference to fig. 5, in the embodiment, the conductive fitting 60 includes: a conductive decoration 610 and a conductive connector 620. The conductive connector 620 is disposed on the side of the conductive sliding cover 20 close to the antenna unit 50 and is connected to the conductive decoration 610 and the conductive sliding cover 20 respectively; the conductive decoration 610 is arranged at intervals with the conductive sliding cover 20 and the middle frame 10; the conductive connecting element 620 drives the conductive decoration 610 to slide relative to the first conductive middle plate 110 when the conductive sliding cover 20 slides.

The conductive decoration 610 is an existing accessory in the electronic device, and has an effect of decoration and beauty when not connected with the conductive sliding cover 20 through the conductive connecting piece 620; when the conductive decoration 610 and the conductive connector 620 form a conductive element, existing accessories in the electronic device are fully utilized, and on the basis that other parts influencing the appearance of the electronic device do not need to be introduced, the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20 can be reduced when the electronic device is in a contraction state, so that the utilization rate of the accessories is improved, the radiation performance of the antenna unit 50 is improved while the cost is reduced, and the user experience is improved. Optionally, the conductive decoration 610 and the conductive connector 620 may be made of metal, so that the conductive decoration and the conductive connector have metallic luster on the basis of realizing conductivity, and the aesthetic effect may be improved.

Alternatively, as shown in fig. 5, the conductive connecting element 620 may be perpendicular to the conductive decoration element 610 and the conductive sliding cover 20, respectively, the plane where the conductive decoration element 610 is located may be perpendicular to the plane where the conductive sliding cover 20 is located, the plane where the conductive decoration element 610 is located may completely cover the conductive connecting element 620, and the plane of the conductive decoration element 610 may extend in the direction of relative sliding. Optionally, the plane of the conductive decoration 610 extends along the relative sliding direction to a size within a range of 1/8 wavelength to 1/2 wavelength, and the wavelength is a central frequency point wavelength when the antenna unit 50 radiates, so as to further avoid resonance between the resonance structure and the antenna unit 50, and at the same time, to suppress transmission of electromagnetic waves radiated by an antenna formed by the conductive sliding cover 20, and to improve the isolation effect between the antenna unit 50 and the conductive sliding cover 20.

It is understood that the plane of the conductive decoration 610 and the conductive connector 620 may extend in the direction of relative sliding, and the extension may be in the range of 1/8 wavelength to 1/2 wavelength. In other embodiments, the conductive fitting 60 may also include only the conductive connector 620, and the conductive connector 620 extends in the direction of relative sliding, and the dimension of extension may be in the range of 1/8 wavelength to 1/2 wavelength.

Referring to fig. 6-8, fig. 6 is a product configuration diagram of the electronic device in a contracted state after the conductive fitting 60 is disposed in the embodiment based on fig. 5, fig. 7 is a radiation efficiency diagram of the antenna in two states of the electronic device in an expanded state and the contracted state before the conductive fitting 60 is not disposed, as shown in fig. 7, the radiation efficiency of the antenna in the contracted state is reduced by 2-3dB in the Wi-Fi 5G frequency band due to the influence of the resonant structure and the actual internal consumption material; fig. 8 is a graph of the radiation efficiency of the antenna in the two states of the electronic device shown in fig. 5, namely the extended state and the retracted state, as shown in fig. 8, after the conductive fitting 60 is disposed, the absorbed electromagnetic energy of 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, which indicates that the radiation efficiency of the antenna unit 50 is indeed improved due to the destruction of the resonant structure.

Referring to fig. 9-10, fig. 9 is a current distribution inside an actual product of the conductive sliding cover 20 of an embodiment when the electronic device with the same product structure before the conductive fitting 60 is set in the retracted state, and fig. 10 is a current distribution inside the conductive sliding cover 20 with the same product structure when the electronic device with the conductive fitting 60 set is set in the retracted state at the same scale, it can be seen that, after the conductive fitting 60, the current on the inner wall of the conductive sliding cover 20 is significantly reduced, which means that the field strength inside the resonant structure is significantly reduced, which means that the electromagnetic energy entering the resonant structure of the antenna unit 50 is reduced, thereby increasing the radiation efficiency of the antenna unit 50, and obtaining the antenna radiation efficiency result as shown in fig. 7.

Fig. 11 is a sixth block diagram of an electronic device according to an embodiment, referring to fig. 11, in this embodiment, the middle frame 10 further includes a frame decoration 130 disposed on the first middle conductive plate 110, and the electronic device further includes: a housing 40.

The housing 40, the housing 40 includes a rear cover 410 disposed opposite to the conductive sliding cover 20 and a frame 420 connected to the rear cover 410, and the housing 40 can slide relatively to the first conductive middle plate 110 along with the conductive sliding cover 20; wherein, the conductive decoration 610 is formed on the bezel 420; when the electronic device is in a retracted state, the housing 40 and the bezel decorative element 130 together form an outer shell to accommodate the middle bezel 10 and the conductive sliding cover 20.

The frame 420 is connected to the conductive sliding cover 20 to slide along with the conductive sliding cover 20 relative to the first conductive middle plate 110; the bezel 420 may be connected to the conductive sliding cover 20 through the conductive decoration 610 and the conductive connector 620, or may be connected to the conductive sliding cover 20 through other components of the conductive decoration 610. For example, the bezel 420 may be fixedly connected to the conductive sliding cover 20 by bolting, welding, and snapping.

The rear cover 410 is disposed opposite to the conductive sliding cover 20, and the rear cover 410 is connected to the frame 420, so that the rear cover 410 slides along with the frame 420 and the conductive sliding cover 20 relative to the first conductive middle plate 110. Optionally, the rear cover 410 is opposite to and spaced apart from the conductive sliding cover 20, a gap may be formed between the rear cover 410 and the conductive sliding cover 20, and when the flexible screen 30 is in the retracted state, at least a part of the non-display area is retracted between the rear cover 410 and the conductive sliding cover 20. Further optionally, the distance between the rear cover 410 and the conductive sliding cover 20 may be greater than the thickness of the flexible screen 30, so as to provide an avoidance space for the movement of the flexible screen 30, and avoid the flexible screen 30 from being abraded due to friction with the rear cover 410 during the movement process. It can be understood that the rear cover 410 and the frame 420 may be an integral structure, or may be relatively independent components, and the two components may be fixedly connected by bonding, welding, clamping, and the like, which is not limited in this embodiment.

As shown in fig. 11, the middle frame 10 further includes a frame decoration 130 disposed on the first conductive middle plate 110, the housing 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 frame decoration 130 and the housing 40 can form a housing together, so as to accommodate the middle frame 10 and the conductive sliding cover 20, and protect the middle frame 10, the conductive sliding cover 20, and the flexible screen 30 disposed on the middle frame 10 and the conductive sliding cover 20.

On one hand, the conductive decoration 610 is formed on the frame 420, and the conductive decoration 610, as a decoration on the frame 420, not only has a function of decoration beauty, but also can drive the hook cover to slide along with the conductive sliding cover 20 relative to the first conductive middle plate 110 in the process of sliding the first conductive middle plate 110 and the second conductive middle plate 120, and can form a complete shell with the frame decoration 130, other components on the frame 420, and the rear cover 410 when the electronic device is in a contracted state, so that the middle frame 10, the conductive sliding cover 20, and the flexible screen 30 can be accommodated and protected; on the other hand, the conductive decoration 610 and the conductive connector 620 form a conductive element, so that existing accessories in the electronic device are fully utilized, and on the basis that other components influencing the appearance of the electronic device do not need to be introduced, the absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20 can be reduced when the electronic device is in a contracted state, so that the cost is reduced, the radiation performance of the antenna unit 50 is improved, and the user experience is improved.

Fig. 12 is a seventh structural block diagram of an electronic device according to an embodiment, and 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 element 70 connected to the middle frame 10 and the conductive sliding cover 20, respectively, so that the middle frame 10 and the conductive sliding cover 20 are disposed in common, thereby breaking the resonant mode of the resonant structure and reducing the electromagnetic energy of the antenna unit 50 absorbed by the conductive sliding cover 20. Moreover, the grounding arrangement of the conductive sliding cover 20 and the middle frame 10 can also suppress the cavity mode between the conductive sliding 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 a side of the first conductive middle plate 110; the grounding piece 70 is respectively connected with the side edge of the conductive sliding cover 20 close to the antenna unit 50 and the side edge of the target conductive middle plate, and at least covers a part of the gap between the conductive sliding cover 20 and the middle frame 10; the target conductive midplane includes at least one of a first conductive midplane 110 and a second conductive midplane 120.

It is understood that when the gap is filled up, the grounding member 70 may be a sheet-shaped metal plate, which may be fixedly connected to the conductive sliding cover 20, the second conductive middle plate 120, and slidably connected to the first conductive middle plate 110, or other embodiments, which are not limited in this embodiment.

When the target middle conductive plate is the second middle conductive plate 120, the conductive sliding cover 20 and the second middle conductive plate 120 are relatively static, so that the short circuit probes can be respectively and fixedly connected to the conductive sliding cover 20 and the second middle conductive plate 120, which is beneficial to improving the stability of the grounding member 70 and avoiding the open circuit condition.

A conductive sliding cover 20; the middle frame 10 is arranged opposite to the conductive sliding cover 20, and includes a first conductive middle plate 110 and a second conductive middle plate 120 which are connected in a sliding manner, the second conductive middle plate 120 is connected with the conductive sliding cover 20, wherein the conductive sliding cover 20 slides along 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 contracted state; an antenna unit 50 disposed on the first conductive middle plate 110; the conductive sliding cover 20 is provided with an opening 80, and when the electronic device is in a contracted state, the opening 80 is disposed adjacent to the antenna unit 50, so as to reduce absorption of electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20.

The conductive sliding cover 20, the middle frame 10, and the antenna unit 50 may refer to the related descriptions in the above embodiments, and are not further described herein.

The conductive sliding cover 20 is provided with an opening 80, and when the electronic device is in a contracted state, the opening 80 is disposed adjacent to the antenna unit 50, so that the opening 80 destroys the original resonant structure formed by the middle frame 10 and the conductive sliding cover 20, and suppresses the resonant mode of the resonant structure, thereby reducing 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 the opening 80, and the existence of the opening 80 is equivalent to extending the length of the side edge of the conductive sliding cover 20, so that the opening 80 extends the current path of the conductive sliding cover 20, thereby changing the resonant frequency of the resonant structure, moving the influence of the resonant structure on the antenna unit 50 out of the frequency band of the nearby antenna, and reducing the absorption of the electromagnetic energy radiated by the antenna unit 50 by the conductive sliding cover 20.

Optionally, the antenna unit 50 is disposed on a side edge of the first middle conductive plate 110, and the side edge of the first middle conductive plate 110 is parallel to the direction in which the second middle conductive plate 120 slides relative to the first middle conductive plate 110; the opening 80 is disposed 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 a retracted state, the opening 80 is disposed adjacent to the antenna unit 50, and the opening 80 physically destroys the resonant structure formed by the conductive sliding cover 20 and the middle frame 10, so as to suppress resonance between the conductive sliding cover 20 and the antenna unit 50, thereby reducing the intensity of current generated by 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 may be at the position shown in fig. 15, or at the position shown in the eleventh structural block diagram of the electronic device in an embodiment shown in fig. 16, and may be specifically adjusted according to the position of the antenna unit 50. The shape of the opening 80 is not limited, and may be, for example, a rectangular opening 80, or may be other shapes, which is not further limited in the present application.

The opening 80 extends along the direction of relative sliding, which is equivalent to extending the length of the side of the conductive sliding cover 20, and the current path of the conductive sliding cover 20 near the side of the antenna unit 50 is extended, so that the resonant frequency of the resonant structure is further changed, and the influence of the resonant structure on the antenna unit 50 is moved out of the frequency band of the nearby antenna. Optionally, the size of the opening 80 extending in the relative sliding direction is in a range of 1/8 wavelength to 1/2 wavelength, the wavelength is a central frequency point wavelength when the antenna unit 50 radiates, for example, a radiation frequency band of the antenna unit 50 is 1427MHz to 2690MHz, and the central frequency point wavelength is 2058.5MHz, so as to further avoid resonance between the resonance structure and the antenna unit 50, and at the same time, to suppress transmission of electromagnetic waves radiated by an antenna constituted by the conductive sliding cover 20, and to improve an isolation effect between the antenna unit 50 and the conductive sliding cover 20.

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

In the electronic device provided in this embodiment, the opening 80 is disposed on the conductive sliding cover 20, so that the resonance structure formed by the conductive sliding cover 20 and the middle frame 10 can be physically destroyed, and the resonance between the conductive sliding cover 20 and the antenna unit 50 is suppressed, 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 when radiating to the antenna unit 50.
