Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] In order to meet users' demand for large-size screens, electronic devices such as folding screens and scroll screens can change the screen size through the dynamic changes of the closing and unfolding of the screen, and avoid the increase in the size of the electronic device. For example: for electronic devices with scroll screens, when the scroll screen is in a closed state, the screen is retracted and placed inside the electronic device through the roller structure on one side of the electronic device. When the scroll screen is in an unfolded state, the screen is extended through the roller structure, similar to the form of scroll unfolding. If the electronic device has a fixed shell and a sliding shell, the scroll screen can be switched between the unfolded state and the closed state by sliding the sliding shell relative to the fixed shell. When the fixed shell and the sliding shell of the electronic device slide to the closed state, the antenna clearance in the thickness direction of the electronic device is extremely small, resulting in limited space for designing the antenna on the top of the electronic device and affecting the antenna performance. Summary of the Invention

[0003] An embodiment of the present application provides an electronic device to solve the problem that the top antenna design space of current electronic devices with a roll-up screen is limited and affects the antenna performance.

[0004] In order to solve the above technical problems, an embodiment of the present application provides an electronic device, including:

[0005] a first shell, wherein a first slot antenna is provided on the first shell;

[0006] a second housing, wherein the first housing is slidably connected to the second housing;

[0007] Wherein, when the metal portion on the second shell overlaps with the first shell, the metal portion on the second shell avoids at least one first slot of the first slot antenna.

[0008] In this way, in the above-mentioned scheme of the present application, the first shell of the electronic device is slidably connected to the second shell. Since the first slot antenna is arranged on the first shell, and the metal part on the second shell overlaps with the first shell, the metal part on the second shell avoids at least one first slot of the first slot antenna, so that when the electronic device switches between the expanded state and the closed state, the first slot antenna can work normally, thereby ensuring the antenna performance, and is not limited to the top space of the electronic device for designing the antenna, which can solve the problem of limited top antenna design space in current electronic devices with scroll screens.

[0018] The following describes exemplary embodiments of the present application in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0019] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides an electronic device, including:

[0020] A first housing 1 , wherein a first slot antenna 111 is provided on the first housing 1 ;

[0021] A second shell 2, wherein the first shell 1 is connected to the second shell 2;

[0022] When the metal portion of the second shell 2 overlaps with the first shell 1 , the metal portion of the second shell 2 avoids the at least one first slot 110 of the first slot antenna 111 .

[0023] Specifically, a slot antenna is an antenna formed by opening a slot on a conductor surface, also known as a slot antenna. Optionally, the slot can be in the shape of a long strip, and the slot can be fed by a transmission line connected across its narrow side, or by a waveguide or resonant cavity. The embodiment of the present application provides a method of using a waveguide for feeding, see Figure 1 and Figure 2 When a radio frequency signal is input to the first feeding point 12 of the first waveguide 11 of the first slot antenna 111, electromagnetic waves are radiated into space through the radio frequency electromagnetic field excited on the first slot 110, thereby realizing the antenna radiation function.

[0024] Optionally, the first shell 1 includes a first frame portion and a first back panel, and the first frame portion is semi-enclosed by the first back panel. If the electronic device also includes a screen, the first back panel is located on the side of the electronic device facing away from the screen. The second shell includes at least a second frame portion, the first side frame 10 in the first frame portion is adjacent to the second side frame 20 in the second frame portion, and the first side frame 10 is arranged parallel to the second side frame 20. In this way, the first frame portion semi-encloses the first back panel, that is, the first shell 1 is formed with an opening, so that the second shell 2 can slide relative to the first shell 1 along the extension direction of the first side frame 10. When the second shell 2 slides from the opening to the inside of the first shell 1, the electronic device is in a closed state, such as Figure 1 When the second housing 2 slides from the opening to the outside of the first housing 1, the electronic device is in an unfolded state, as shown in FIG. Figure 2 shown.

[0025] It should be noted that the overlap between the metal part on the second shell 2 and the first shell 1 includes but is not limited to: the electronic device is in a closed state, and the metal part on the second shell 2 overlaps with the first shell 1 during the switching process of the electronic device between the closed state and the unfolded state.

[0026] It should also be noted that when the metal portion on the second shell 2 overlaps with the first shell 1, the metal portion on the second shell 2 avoids at least one first slot 110 of the first slot antenna 111, and this is not limited to the following: as long as the metal portion on the second shell 2 overlaps with the first shell 1, the metal portion on the second shell 2 avoids at least one first slot 110 of the first slot antenna 111. For example, in one or some states during the sliding of the first shell 1 relative to the second shell 2, the metal portion on the second shell 2 may block at least one first slot 110 of the first slot antenna 111. However, when the first shell 1 slides to the target position relative to the second shell 2 (such as when the scroll screen is fully unfolded, 1 / 2 unfolded, 1 / 3 unfolded, or when a screen of other sizes is unfolded for use), the metal portion on the second shell 2 can avoid at least one first slot 110 of the first slot antenna 111.

[0027] Optionally, the second side frame 20 is a metal frame, i.e., the metal portion, so as to facilitate the installation of more antennas on the second housing 2, thereby increasing the number of antennas in the electronic device. Furthermore, when the metal portion of the second housing 2 overlaps with the first housing 1, the metal portion of the second housing 2 avoids at least one first slot 110 of the first slot antenna 111, allowing the first slot antenna 111 to operate normally when the electronic device switches between the expanded and closed states. For example, the metal portion of the second housing 2 avoiding at least one first slot 110 of the first slot antenna 111 includes, but is not limited to: the metal portion of the second housing 2 not blocking the entire first slot 110; the metal portion of the second housing 2 only blocking a portion of the first slot 110 and not blocking another portion of the first slot 110; for a first slot 110, the second housing does not block the entire first slot 110; for a first slot 110, the second housing only blocks a portion of the first slot 110 and not blocks another portion of the first slot 110, etc., and the present embodiment is not limited thereto.

[0028] In the above scheme, the first shell 1 and the second shell 2 of the electronic device are slidably connected. Since the first slot antenna 111 is arranged on the first shell 1, and when the metal part on the second shell overlaps with the first shell, the metal part on the second shell 2 avoids at least one first slot 110 of the first slot antenna 111, so that when the electronic device switches between the unfolded state and the closed state, the first slot antenna 111 can work normally, thereby ensuring the antenna performance, and is not limited to the top space of the electronic device for antenna design, which can solve the problem of limited top antenna design space in current electronic devices with scroll screens.

[0029] Optionally, the first shell 1 includes: a first side frame 10 and a first back panel, the first side frame 10 is arranged on the edge of the first back panel; the first slot antenna 111 is arranged on the first side frame 10, or the first slot antenna 111 is arranged on the first back panel.

[0030] In this embodiment, the first slot antenna 111 is disposed on the first back panel of the first housing 1, concentrating the energy radiated by the antenna on the side of the electronic device facing away from the screen, thereby reducing the specific absorption rate (SAR) value at the top of the electronic device. Alternatively, the first slot antenna 111 can be disposed on the first side frame 10 and used in conjunction with a module for reducing the SAR value to minimize its impact on the human body.

[0031] Optionally, the first slot antenna is provided on the first side frame 10, or the first slot antenna 111 is provided on the first back panel and close to the first side frame 10, and under the condition that the metal part on the second shell 2 can avoid at least one first slot 110 of the first slot antenna 111, other antenna structures can be provided on the second side frame 20 (i.e., the metal part), such as a second slot antenna or a metal branch antenna on the metal part. In this way, since the clearance requirement of the slot antenna is small, it can be ensured that the antenna structures on the first shell 1 and the second shell 2 can work normally when the electronic device is in the unfolded state; when the electronic device is in the closed state, the metal part can avoid at least one first slot 110 of the first slot antenna 111, which can also enable the antenna to work normally, thereby solving the problem of limited design space for the top antenna of the current electronic device with a roll-up screen, and is conducive to ensuring antenna performance.

[0032] As an optional embodiment, Figure 3 and Figure 4 As shown, a second slot antenna 211 is provided on the metal part; wherein, when the metal part overlaps with the first shell 1 , the second slot 210 of the second slot antenna 211 is connected to at least one of the first slots 110 .

[0033] In this embodiment, by arranging a second slot antenna 211 on the second shell 2, when the metal part overlaps with the first shell 1, it can be ensured that the second slot antenna 211 or the first slot antenna 111 works normally, or the second slot antenna 211 and the first slot antenna 111 work in combination in a new antenna radiation mode, etc.

[0034] Optionally, when the metal portion does not overlap with the first housing 1, the second slot antenna 211 and the first slot antenna 111 can operate independently, or the second slot antenna 211 and the first slot antenna 111 can operate in combination in a new antenna radiation pattern. The new antenna radiation pattern is different from the antenna radiation pattern of the first slot antenna 111 and the second slot antenna 211 operating independently.

[0035] Optionally, the slot spacing of the second slot antenna 211 is a positive integer multiple of the slot spacing of the first slot antenna 111. In this way, when the metal portion overlaps with the first housing 1, it can be ensured that the second slot 210 of the second slot antenna 211 is arranged opposite to at least one of the first slots 110, that is, the second slot 210 of the second slot antenna 211 is directly opposite or overlaps with at least one of the first slots 110.

[0036] Optionally, the first shell 1 is provided with a first waveguide 11; the first slot 110 is opened on the first waveguide 11 and the first slot antenna 111 is formed, and the first waveguide 11 is provided with a first opening; when the second shell 2 slides relative to the first shell 1, the second slot antenna 211 passes through the first opening and is located on the inner side of the first waveguide 11.

[0037] For example: the inside of the first side frame 10 is hollowed out to form the first waveguide 11. Or a metal plate parallel to the first side frame 10 is set inside the first shell, and the metal plate and part of the frame of the reused first shell constitute the first waveguide 11, etc. The embodiments of the present application are not limited to this. When a radio frequency signal is input to the first feeding point 12 of the first waveguide 11 of the first slot antenna 111, electromagnetic waves are radiated into space through the radio frequency electromagnetic field excited on the first slot 110, thereby realizing the antenna radiation function. In addition, a first opening is formed on the first side frame 10, so that when the second shell 2 slides relative to the first shell 1, the second side frame of the second shell 2 can enter and exit the interior of the first waveguide 11, that is, the electronic device can be switched between the expanded state and the closed state.

[0038] Optionally, a first slot 110 is formed in the portion of the first backplane where the first waveguide 11 is formed, forming the first slot antenna 111. This can reduce the impact of antenna radiation energy on the human body and reduce SAR. Of course, the first slot 110 can also be formed in the portion of the first side frame 10 where the first waveguide 11 is formed, forming the first slot antenna 111, etc., and the present embodiment is not limited thereto.

[0039] Optionally, the metal part on the second shell 2 is provided with a second waveguide 21; the second slot 210 is opened on the second waveguide 21 to form a second slot antenna 211, and the first end of the second waveguide 21 is a closed structure; when the second shell 2 slides relative to the first shell 1, the first end of the second waveguide 21 passes through the first opening and is located on the inner side of the first waveguide 11, and the first end of the second waveguide 21 closes the first opening.

[0040] Specifically, the design method of the second waveguide 21 can be the same as or different from that of the first waveguide 11, such as hollowing out the interior of the second side frame to form the second waveguide 21. Alternatively, a metal plate parallel to the second side frame is provided inside the second shell, and the metal plate and a portion of the frame of the second shell are reused to form the second waveguide 21, etc. The embodiments of the present application are not limited to this. When a radio frequency signal is input to the second feeding point 22 of the second waveguide 21 of the second slot antenna 211, electromagnetic waves are radiated into space through the radio frequency electromagnetic field excited on the second slot 210, thereby realizing the antenna radiation function.

[0041] Optionally, when a first slot 110 is formed on the portion of the first waveguide 11 on the first side frame 10 to form the first slot antenna 111, a second slot 210 can also be formed on the portion of the second waveguide 21 on the second side frame 20 (i.e., the metal portion) to form the second slot antenna 211, so as to ensure that when the second shell 2 slides relative to the first shell 1, the metal portion on the second shell 2 can avoid at least one first slot 110 of the first slot antenna 111 to ensure the antenna radiation function.

[0042] Optionally, the second shell 2 may include a second back panel, and the second frame portion of the second shell 2 is arranged to surround the second back panel. For example, when a first slot 110 is opened on the portion of the first waveguide 11 formed on the first back panel to form the first slot antenna 111, a second slot 210 is opened on the portion of the second waveguide 21 formed on the second back panel (i.e., the metal portion) to form the second slot antenna 211, and the metal portion can avoid at least one first slot 110 of the first slot antenna 111 to ensure that the antenna radiation function is realized while reducing the impact of the antenna radiation energy on the human body, thereby reducing SAR.

[0043] In this embodiment, since the first end of the second waveguide 21 is a closed structure, when the metal portion of the second shell 2 does not overlap with the first shell 1 (such as when the electronic device is in the unfolded state, such as Figure 4As shown), the first slot antenna 111 and the second slot antenna 211 can work independently; when the metal part on the second shell 2 overlaps with the first shell 1 (such as the electronic device is in a closed state, such as Figure 3 As shown), the first slot antenna 111 or the second slot antenna 211 works, or the first slot antenna 111 and the second slot antenna 211 work in combination in a new antenna radiation mode, etc.

[0044] For example, if the slot spacing of the second slot antenna 211 is the same as the slot spacing of the first slot antenna 111, and the number of the second slots 210 of the second slot antenna 211 is less than or equal to the number of the first slots 110 of the first slot antenna 111, if the electronic device is in a closed state, such as Figure 3 As shown, each second slot 210 of the second slot antenna 211 can overlap with the first slot 110 of the first slot antenna 111, that is, each second slot 210 of the second slot antenna 211 can be exposed. At this time, when excited by the second feeding point 22, the second slot antenna 211 can work normally. Figure 4 As shown, since the first end of the second waveguide 21 is a closed structure, it can be excited by the first feeding point 12 and the second feeding point 22 respectively, so the first slot antenna 111 and the second slot antenna 211 can work independently.

[0045] For another example, if the slot spacing of the second slot antenna 211 is the same as the slot spacing of the first slot antenna 111, and the number of second slots 210 of the second slot antenna 211 is greater than the number of first slots 110 of the first slot antenna 111, if the electronic device is in a closed state, each first slot 110 of the first slot antenna 111 can overlap with the second slot 210 of the second slot antenna 211, that is, each first slot 110 of the first slot antenna 111 can be exposed. In this case, the first slot antenna 111 can operate normally when excited by the first feeding point 12. If the electronic device is in an unfolded state, since the first end of the second waveguide 21 is a closed structure, it can be excited by the first feeding point 12 and the second feeding point 22 respectively, so that the first slot antenna 111 and the second slot antenna 211 can both operate independently.

[0046] Optionally, based on the above embodiment, when the slot spacing of the second slot antenna 211 is N times (N is a positive integer greater than 1) the slot spacing of the first slot antenna 111, by setting the number of first slots 110 and second slots 210 to be different, when the electronic device is in a closed state, each first slot 110 is exposed, or each second slot 210 is exposed, etc., so that the first slot antenna 111 or the second slot antenna 211 can work normally.

[0047] For another example: when the slot spacing of the second slot antenna 211 is N times (N is a positive integer greater than 1) the slot spacing of the first slot antenna 111, if when the electronic device is in a closed state, only part of the first slot 110 is exposed, or only part of the second slot 210 is exposed, or part of the first slot 110 is exposed, or part of the slot of the second slot 210 is exposed, etc., it is equivalent to that the slot spacing of the first slot antenna 111 and the second slot antenna 211 are both changed. At this time, the first slot antenna 111 and the second slot antenna 211 can be combined to work in a new antenna radiation mode, etc., which is beneficial to increase the antenna coverage frequency band of the electronic device.

[0048] Optionally, the operating frequency band of the first slot antenna 111, the operating frequency band of the second slot antenna 211, and the operating frequency band of the combination of the first slot antenna 111 and the second slot antenna 211 can be designed according to the frequency band required by the electronic device, and the embodiment of the present application does not make specific limitations.

[0049] In the above embodiment, the top antenna of the electronic device is formed by disposing a first waveguide 11 and a first slot antenna 111 on the first housing 1, and disposing a second waveguide 21 and a second slot antenna 211 on the second housing 2. The larger first waveguide 11 is nested within the smaller second waveguide 21. Furthermore, since slot antennas require less clearance, the design of the top antenna of the electronic device is more flexible. Furthermore, the slots of the first slot antenna 111 and the second slot antenna 211 are located on the back panel on the side facing away from the screen, which helps reduce the impact of SAR on the human body.

[0050] As another optional embodiment, Figure 5 and Figure 6 As shown, the metal part is provided with a third waveguide 23; the second slot 210 is opened on the third waveguide 23 to form the second slot antenna 211, and the first end of the third waveguide 23 is provided with a second opening; when the second shell 2 slides relative to the first shell 1, the first end of the third waveguide 23 passes through the first opening and is located on the inner side of the first waveguide 11, and the first opening is connected to the second opening.

[0051] In this embodiment, since the first end of the third waveguide 23 is provided with a second opening, when the metal portion of the second shell 2 does not overlap with the first shell 1 (such as when the electronic device is in the unfolded state, such as Figure 6As shown in FIG, the first slot antenna 111 and the second slot antenna 211 form a third slot antenna 113, and the third slot antenna 113 can operate in an antenna radiation mode different from that of the first slot antenna 111 and the second slot antenna 211, so that the third waveguide 23 can be used as a supplement to the first waveguide 11 to obtain higher radiation efficiency. In the case where the metal part on the second shell 2 overlaps with the first shell 1 (such as when the electronic device is in a closed state, such as Figure 5 As shown), the first slot antenna 111 and the second slot antenna 211 work in combination in a new antenna radiation mode, which can be specifically designed according to the frequency band required by the electronic device, and the embodiments of the present application are not limited thereto.

[0052] In addition, since the first end of the third waveguide 23 is provided with a second opening, and when the metal portion on the second shell 2 does not overlap with the first shell 1, the third waveguide 23 can serve as a supplement to the first waveguide 11, that is, the first slot antenna 111 and the second slot antenna 211 form a third slot antenna 113 to work. At this time, a feeding point can be set to reduce the layout difficulty of setting a feeding point on the second shell. For example, the first feeding point 12 set on the first waveguide 11 is excited so that the third slot antenna 113 can work when the metal portion on the second shell 2 does not overlap with the first shell 1, and when the metal portion on the second shell 2 overlaps with the first shell 1, the first feeding point 12 can also be used to excite the second slot antenna 211 or the first slot antenna 111, or the first slot antenna 111 and the second slot antenna 211 are combined into a new slot antenna to work, etc. The embodiments of the present application are not limited thereto.

[0053] Optionally, the slot spacing of the second slot antenna 211 is a positive integer multiple of the slot spacing of the first slot antenna 111. In this way, when the metal portion of the second housing 2 overlaps with the first housing 1, it can be ensured that the second slot 210 of the second slot antenna 211 is arranged opposite to at least one of the first slots 110, that is, the second slot 210 of the second slot antenna 211 overlaps or directly faces at least one of the first slots 110.

[0054] Alternatively, as Figure 7 、 Figure 8 and Figure 9 As shown, when the first slot antenna 111 is arranged on the first back plate of the first shell 1, there is a spacing area between the first slot 110 and the first side frame 10 of the first shell 1; the metal part is provided with a branch antenna 24, and when the metal part overlaps with the first shell 1, the branch antenna 24 is located in the spacing area.

[0055] In this embodiment, when the first slot antenna 111 is arranged on the first back plate of the first shell 1, a certain interval can be set between the first slot 110 and the first side frame 10 to serve as an accommodating area for the branch antenna 24 on the second side frame, so that when the second shell 2 slides to the first range relative to the first shell 1, the branch antenna 24 is located in the interval area, such as the branch antenna 24 is tightly closed against the first side frame 10 and does not block the first slot 110, so as to ensure that the first slot antenna 111 can work normally.

[0056] Optionally, the branch antenna 24 may use a portion of the frame of the second housing as an antenna radiator, and operate through excitation by a feed source connected to the antenna radiator.

[0057] Optionally, a fracture 25 is provided on the metal portion, and the metal portion is divided by the fracture (25) to form the branch antenna (24).

[0058] In this embodiment, when the metal part overlaps with the first shell 1, since the slit 25 is located between the branch antenna 24 and the first slot antenna 111, the branch antenna 24 and the first slot antenna 111 can operate independently, and the isolation between the branch antenna 24 and the first slot antenna 111 can be increased through the slit 25, thereby ensuring the antenna radiation performance.

[0059] Optionally, the operating frequency band of the branch antenna 24 is a WIFI frequency band. Since the electronic device is in the unfolded state, the user is usually watching a video or playing a game, and setting the operating frequency band of the branch antenna 24 to the WIFI frequency band can ensure that the electronic device has better wireless network performance in the unfolded state.

[0060] Taking an electronic device with a roll-up screen as an example, the roll-up screen is arranged on the second shell 2, and the second shell 2 slides relative to the first shell 1, so that the roll-up screen is unfolded or rolled up into the interior of the electronic device. Since the first shell 1 requires space to store the roll-up screen, the antenna layout space of the first shell 1 is limited, and the clearance is very small. In the embodiment of the present application, a slot antenna (such as a waveguide slot antenna) is designed on the first shell 1. Since the slot antenna has a small requirement for the antenna clearance, the first shell 1 can be compatible with the accommodation of the roll-up screen and the antenna design problem; and the slot antenna is a semi-enclosed structural radiation antenna, and its antenna pattern is highly directional, and the SAR hotspot is more concentrated in the direction of the radiation slot. Therefore, the radiation slot can be opened on the side of the electronic device facing away from the screen, which can effectively reduce the impact of SAR on the human body.

[0061] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
