DETAILED DESCRIPTION

[0060] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0061] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0062] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0063] Foldable electronic devices, such as foldable phones and foldable computers, are widely used in people's daily lives and work. Foldable phones include both vertically foldable and horizontally foldable phones. Foldable devices typically have both unfolded and folded states. In the folded state, the overall size of the device changes, generating inherent resonances that are difficult to tune using conventional tuners or converters, resulting in a significant reduction in antenna radiation performance.

[0064] A foldable device generally comprises a first part and a second part that can rotate relative to each other. In the folded state, there is inevitably a gap between the opposing surfaces of the first part and the second part, which stimulates a slot antenna. The physical length of the slot antenna is related to the length of the first part and / or the length of the second part. In the prior art, such as Figure 1A and Figure 1B As shown in the figure, the electrical length of the antenna of an electronic device in the unfolded and folded states is represented by L. The electrical length of the antenna in the unfolded state is greater than that in the folded state. In the folded state, the electrical length of the antenna is fixed, affecting the frequency band covered by the antenna and its radiation performance.

[0065] The present disclosure provides an electronic device that can adjust the physical length of an antenna in a folded state, enabling the antenna to cover a wider frequency band and improving the antenna's radiation performance. For example, in the folded state, the antenna can cover low, mid, and high frequency bands.

[0066] The electronic device of the present disclosure is described below with reference to FIG. 1 to FIG. 9 .

[0067] In the embodiments of the present disclosure, Figures 2 to 4As shown, the electronic device includes a first body 10, a second body 20, a first electrical connection portion 30, and a second electrical connection portion 40. The first body 10 and the second body 20 are rotatably connected to enable the electronic device to switch between an unfolded state and a folded state. The first electrical connection portion 30 is provided on the first body 10, and the second electrical connection portion 40 is provided on the second body 20. In the unfolded state, the first electrical connection portion 30 and the second electrical connection portion 40 are separated; in the folded state, the first electrical connection portion 30 and the second electrical connection portion 40 are dynamically connected.

[0068] Electronic devices include foldable phones and foldable computers, among others. Foldable phones include vertically foldable phones and horizontally foldable phones. A first body 10 is rotatably connected to a second body 20 via a rotation mechanism. The rotation mechanism may be a hinge structure commonly used in foldable devices, and the specific description of the rotation mechanism is omitted here. The central axis of the rotation mechanism is defined as the rotation axis, about which the first body 10 and the second body 20 can rotate.

[0069] The first body 10 includes a first housing 14, components located within the first housing 14, and a first portion of the display screen. The second body 20 includes a second housing 24, components located within the second housing 24, and a second portion of the display screen. In the unfolded state, the first and second bodies 10, 20 can hover at a target location. The angle between the first and second bodies 10, 20 can be adjusted to 90 degrees, 135 degrees, 180 degrees, and other angles, allowing for flexible adjustment based on usage requirements. In the folded state, the first and second bodies 10, 20 face each other, with the angle between them being 0 degrees or close to 0 degrees, and the first and second portions of the display screen facing each other.

[0070] It is understood that the electronic device also includes an antenna. Part of the antenna is located in the first body 10, and the antenna section located in the first body 10 is defined as a first antenna unit 61. Part of the antenna is located in the second body 20, and the antenna section located in the second body 20 is defined as a second antenna unit 62. The antenna includes a first antenna unit 61 and a second antenna unit 62.

[0071] The first electrical connection portion 30 and the second electrical connection portion 40 are made of conductive materials and can be electrically connected when in contact with each other.

[0072] In some embodiments, the first body 10 includes a first housing 14, and the first electrical connection portion 30 can be fixed to the first housing 14 by screwing, snapping, or the like, or can be movably connected to the first housing 14 via an elastic member. For example, the first housing 14 includes a first middle frame, and the first electrical connection portion 30 can be fixed to the first middle frame by welding, or can be movably connected to the first middle frame via an elastic member.

[0073] In some embodiments, the second body 20 includes a second housing 24, and the second electrical connection portion 40 can be fixed to the second housing 24 by screwing, snapping, or the like, or the second electrical connection portion 40 can be movably connected to the second housing 24 via an elastic member. For example, the second housing 24 includes a second middle frame, and the second electrical connection portion 40 can be fixed to the second middle frame by welding, or the second electrical connection portion 40 can be movably connected to the second middle frame via an elastic member.

[0074] In the folded state, Figure 5A As shown, the first body 10 and the second body 20 are opposite to each other, and the surface of the first body 10 facing the second body 20 is defined as the first surface 100 of the first body 10, and the surface of the second body 20 facing the first body 10 is defined as the second surface 200 of the second body 20. There is inevitably a gap between the first surface 100 and the second surface 200. The first antenna unit 61 and the second antenna unit 62 excite a slot antenna between the first surface 100 and the second surface 200. The physical length of the slot antenna is equal to the length of the first body 10 or the length of the second body 20. The physical length of the slot antenna is positively correlated with the wavelength. Different wavelengths are suitable for covering different frequency bands, including low frequency bands, mid-frequency bands, and high frequency bands. The physical length of the slot antenna can be changed by adjusting the electrical connection state and electrical connection position of the first electrical connection part 30 and the second electrical connection part 40.

[0075] In the folded state, the first electrical connection part 30 and the second electrical connection part 40 are dynamically connected. Dynamic connection means that the first electrical connection part 30 and the second electrical connection part 40 can be in an electrically connected state or a non-electrically connected state. According to the working mode of the electronic device, the position of at least one of the first electrical connection part 30 and the second electrical connection part 40 can be adjusted so that the two are in an electrically connected state or a non-electrically connected state. The physical length of the slot antenna in the electrically connected state is smaller than the physical length of the slot antenna in the non-electrically connected state. The size of the physical length can be adjusted according to the position where the first electrical connection part 30 and the second electrical connection part 40 contact each other so that the slot antenna can cover the low frequency band, the medium frequency band or the high frequency band to meet the usage requirements under different working modes.

[0076] For example, the first electrical connection part 30 and the second electrical connection part 40 are in a non-electrically connected state, and the physical length is large. The slot antenna can cover the low frequency band, and the electronic device has better radiation performance in the low frequency band. The first electrical connection part 30 and the second electrical connection part 40 are in an electrically connected state, and the position where the first electrical connection part 30 and the second electrical connection part 40 are electrically connected is located in the middle area of ​​the first body 10 and the second body 20. The slot antenna can cover the medium frequency band, and the electronic device has better radiation performance in the medium frequency band. The position where the first electrical connection part 30 and the second electrical connection part 40 are electrically connected is close to the end area of ​​the first body 10 and the second body 20. The slot antenna can cover the high frequency band, and the electronic device has better radiation performance in the high frequency band. It is also possible to cover different frequency bands of the low frequency band by adjusting the position where the first electrical connection part 30 and the second electrical connection part 40 are electrically connected in the folded state.

[0077] In the folded state, the end surface of the first electrical connection portion 30 is flush with or slightly higher than the first surface 100 of the first body 10, and / or the end surface of the second electrical connection portion 40 is flush with or slightly higher than the second surface 200 of the second body 20, so that the first electrical connection portion 30 and the second electrical connection portion 40 can contact each other, so that they can be electrically connected, that is, they are in an electrically connected state. It will be understood that in the folded state, at least one of the first electrical connection portion 30 and the second electrical connection portion 40 can move, so that the electrical connection between them is disconnected, that is, they are in a non-electrically connected state.

[0078] It can be understood that in the unfolded state, the first electrical connection part 30 and the second electrical connection part 40 are separated, the first electrical connection part 30 is smaller in size along the direction perpendicular to the thickness of the first body 10, and the second electrical connection part 40 is smaller in size along the direction perpendicular to the thickness of the second body 20, thereby reducing the impact on the appearance of the electronic device.

[0079] In an embodiment of the present disclosure, a first electrical connection portion 30 is provided on the first body 10, and a second electrical connection portion 40 is provided on the second body 20. When the electronic device is in a folded state, the first electrical connection portion 30 and the second electrical connection portion 40 can be in an electrically connected state or a non-electrically connected state, thereby realizing the adjustment of the physical length of the slot antenna. The physical length is positively correlated with the wavelength. By adjusting the physical length, the slot antenna can cover low frequency bands, medium frequency bands or high frequency bands, thereby improving the radiation performance of the electronic device in a folded state.

[0080] In the embodiments of the present disclosure, Figure 2 、 Figure 3As shown in Figure 5, the first electrical connection part 30 includes first electrical connection units 31 arranged at intervals, and the arrangement direction of the multiple first electrical connection units 31 is perpendicular to the rotation axis of the electronic device; and / or the second electrical connection part 40 includes second electrical connection units 41 arranged at intervals, and the arrangement direction of the multiple second electrical connection units 41 is perpendicular to the rotation axis of the electronic device.

[0081] The first body 10 and the second body 20 are rotatably connected by a rotating mechanism, and the central axis of the rotating mechanism is the rotating axis. The first body 10 can be rectangular or approximately rectangular, and the first body 10 has a first direction and a second direction, the first direction is perpendicular to the rotating axis, and the second direction is parallel to the rotating axis. The second body 20 can be rectangular or approximately rectangular, and the second body 20 has a first direction and a second direction, the first direction is perpendicular to the rotating axis, and the second direction is parallel to the rotating axis. In the case where the electronic device is a vertically folded electronic device, the first direction is the length direction, and the second direction is the width direction. In the case where the electronic device is a horizontally folded electronic device, the first direction is the width direction, and the second direction is the length direction. The end of the first body 10 away from the rotating mechanism is defined as the first end 13, and the end of the second body 20 away from the rotating mechanism is defined as the second end 23.

[0082] like Figure 3 As shown, the number of first electrical connection units 31 is not specifically limited, and can be one, two, or more. When the number of first electrical connection units 31 is multiple, the arrangement direction of the multiple first electrical connection units 31 is perpendicular to the rotation axis. The number of second electrical connection units 41 is not specifically limited, and can be one, two, or more. When the number of second electrical connection units 41 is multiple, the arrangement direction of the multiple second electrical connection units 41 is perpendicular to the rotation axis. Here, "vertical" includes the situation described and the situation similar to the situation described, and the range of the similar situation is within the acceptable deviation range. For example, "vertical" includes absolute vertical and approximate vertical, where the acceptable deviation range of approximate vertical is, for example, a deviation within 5°. For example, the angle between the arrangement direction and the rotation axis can be 90 degrees, 85 degrees, 95 degrees, etc.

[0083] like Figure 5A As shown, in some embodiments, there is one first electrical connection unit 31 and multiple second electrical connection units 41. For example, there are seven second electrical connection units 41, which are spaced apart along the length of the second body 20. The first electrical connection unit 31 can be approximately rectangular, and the second electrical connection unit 41 can be approximately cylindrical. In the folded state, the projection area of ​​the first electrical connection unit 31 on the second body 20 can cover the area where the seven second electrical connection units 41 are located.

[0084] In the folded state, any one of the seven second electrical connection units 41 can be adjusted to contact the first electrical connection unit 31 to adjust the physical length of the slot antenna. The positions of the seven second electrical connection units 41 are defined as the first position, the second position...the seventh position, respectively. The first position is away from the second end 23 of the second body 20, and the seventh position is close to the second end 23 of the second body 20. For example, the end surface of the first electrical connection unit 31 is slightly higher than the first surface 100 of the first body 10. The second electrical connection unit 41 can be moved toward the first body 10 in a direction perpendicular to the second body 20 until the second electrical connection unit 41 contacts the first electrical connection unit 31, thereby achieving electrical connection between the second electrical connection unit 41 and the first electrical connection unit 31. Flexible adjustment of the physical length is achieved based on the electrical connection position of the second electrical connection unit 41 and the first electrical connection unit 31.

[0085] like Figure 5B As shown, in some embodiments, there are multiple first electrical connection units 31 and one second electrical connection unit 41. For example, there are seven first electrical connection units 31, which are spaced apart along the length of the first body 10. The first electrical connection unit 31 can be approximately cylindrical, and the second electrical connection unit 41 can be approximately rectangular. In the folded state, the projection area of ​​the second electrical connection unit 41 on the first body 10 can cover the area where the seven first electrical connection units 31 are located.

[0086] In the folded state, any one of the seven first electrical connection units 31 can be adjusted to contact the second electrical connection unit 41 to achieve adjustment of the physical length of the slot antenna. The positions of the seven first electrical connection units 31 are defined as the first position, the second position...the seventh position, respectively. The first position is away from the first end 13 of the first body 10, and the seventh position is close to the first end 13 of the first body 10. For example, the end face of the second electrical connection unit 41 is slightly higher than the second surface 200 of the second body 20. The first electrical connection unit 31 can be moved toward the second body 20 in a direction perpendicular to the first body 10 until the first electrical connection unit 31 contacts the second electrical connection unit 41, thereby achieving electrical connection between the first electrical connection unit 31 and the second electrical connection unit 41. Flexible adjustment of the physical length is achieved according to the electrical connection position of the first electrical connection unit 31 and the second electrical connection unit 41.

[0087] like Figure 5CAs shown, in some embodiments, there are multiple first electrical connection units 31 and multiple second electrical connection units 41. For example, there are eight first electrical connection units 31, which are spaced apart along the length of the first body 10; and there are four second electrical connection units 41, which are spaced apart along the length of the second body 20. In the folded state, two first electrical connection units 31 are corresponding to one second electrical connection unit 41.

[0088] Alternatively, there are seven first electrical connection units 31, which are spaced apart along the length of the first body 10; and there are seven second electrical connection units 41, which are spaced apart along the length of the second body 20. In the folded state, the first electrical connection units 31 and the second electrical connection units 41 correspond one to one.

[0089] The following embodiment takes the number of the first electrical connection units 31 and the number of the second electrical connection units 41 as seven as an example to illustrate the structure of the above electronic device.

[0090] In the folded state, any of the seven first electrical connection units 31 can be adjusted to contact the corresponding second electrical connection unit 41, or any of the seven second electrical connection units 41 can be adjusted to contact the corresponding first electrical connection unit 31, thereby adjusting the physical length of the slot antenna. The positions of the seven first electrical connection units 31 and the seven second electrical connection units 41 are defined as the first position, the second position, ..., and the seventh position, respectively, with the first position being away from the ends of the first body 10 and the second body 20, and the seventh position being closer to the ends of the first body 10 and the second body 20. For example, the first electrical connection unit 31 at the first position can be moved toward the second body 20 in a direction perpendicular to the first body 10 until the first electrical connection unit 31 at the first position contacts the second electrical connection unit 41. For example, the second electrical connection unit 41 at the first position can be moved toward the first body 10 in a direction perpendicular to the second body 20 until the second electrical connection unit 41 at the first position contacts the first electrical connection unit 31. For example, the first electrical connection unit 31 at the first position can be moved toward the second body 20 in a direction perpendicular to the first body 10, and the second electrical connection unit 41 at the first position can be moved toward the first body 10 in a direction perpendicular to the second body 20, until the first electrical connection unit 31 and the second electrical connection unit 41 at the first position come into contact. The first electrical connection unit 31 and the second electrical connection unit 41 come into contact, thereby achieving electrical connection between the first electrical connection unit 31 and the second electrical connection unit 41. Flexible adjustment of the physical length is achieved based on the electrical connection positions of the first electrical connection unit 31 and the second electrical connection unit 41.

[0091] like Figure 6A As shown, the plurality of first electrical connection units 31 and the plurality of second electrical connection units 41 are all in a non-electrically connected state, and the physical length of the slot antenna is as follows: Figure 6A As shown in L1.

Figure 6G As shown, the first electrical connection unit 31 and the second electrical connection unit 41 at the sixth position are in an electrically connected state, and the physical length of the slot antenna is as follows: Figure 6G As shown in L7. Figure 6H As shown, the first electrical connection unit 31 and the second electrical connection unit 41 at the seventh position are in an electrically connected state, and the physical length of the slot antenna is as follows: Figure 6H As shown in L8.

[0092] The reflection coefficient and system efficiency of the antenna in the electrically connected state of the first electrical connection unit 31 and the second electrical connection unit 41 at different positions are as follows: Figure 7A and Figure 7B shown.

[0093] like Figure 7A As shown, the reflection coefficient curve in the non-electrically connected state is represented by S1, the reflection coefficient curve when the two electrically connected units at the first position are in the electrically connected state is represented by S2, the reflection coefficient curve when the two electrically connected units at the second position are in the electrically connected state is represented by S3, the reflection coefficient curve when the two electrically connected units at the third position are in the electrically connected state is represented by S4, the reflection coefficient curve when the two electrically connected units at the fourth position are in the electrically connected state is represented by S5, the reflection coefficient curve when the two electrically connected units at the fifth position are in the electrically connected state is represented by S6, and the reflection coefficient curve when the two electrically connected units at the sixth position are in the electrically connected state is represented by S7.

[0094] like Figure 7B As shown, the system efficiency curve in the non-electrically connected state is represented by S1, the system efficiency curve when the two electrically connected units at the first position are in the electrically connected state is represented by S2, the system efficiency curve when the two electrically connected units at the second position are in the electrically connected state is represented by S3, the system efficiency curve when the two electrically connected units at the third position are in the electrically connected state is represented by S4, the system efficiency curve when the two electrically connected units at the fourth position are in the electrically connected state is represented by S5, the system efficiency curve when the two electrically connected units at the fifth position are in the electrically connected state is represented by S6, and the system efficiency curve when the two electrically connected units at the sixth position are in the electrically connected state is represented by S7.

[0095] The radiation performance of the antenna is related to the reflection coefficient and the system efficiency. The lower the reflection coefficient and the higher the system efficiency, the better the radiation performance. After the first electrical connection unit 31 and the second electrical connection unit 41 at different positions are electrically connected, Figure 7A The lowest values ​​of the seven reflection coefficient curves change. Figure 7B The highest values ​​of the seven system efficiency curves are different. Figure 7A It can be seen that the lowest values ​​of the seven reflection coefficient curves correspond to different frequencies. Figure 7B It can be seen that the frequencies corresponding to the highest values ​​of the seven system efficiency curves are different. Figure 7A The seven reflection coefficient curves and Figure 7B The seven system efficiency curves in the figure show the suitable operating frequency bands of electronic devices when electrically connected at different positions. In the non-electrically connected state, the operating frequency band can be 0.6~0.65GHz; when the two electrically connected units at the first position are electrically connected, the operating frequency band can be 0.65~0.71GHz; when the two electrically connected units at the second position are electrically connected, the operating frequency band can be 0.71~0.73GHz; when the two electrically connected units at the third position are electrically connected, the operating frequency band can be 0.73~0.76GHz; when the two electrically connected units at the fourth position are electrically connected, the operating frequency band can be 0.76~0.79GHz; when the two electrically connected units at the fifth position are electrically connected, the operating frequency band can be 0.79~0.86GHz; and when the two electrically connected units at the sixth position are electrically connected, the operating frequency band can be 0.86~0.96GHz. Therefore, when two electrically connected units at different positions are electrically connected, they can correspond to different operating modes.

[0096] Multiple first electrical connection units 31 are spaced apart along the first direction of the first body 10 and / or multiple second electrical connection units 41 are spaced apart along the first direction of the second body 20. The electrical connection positions of the first electrical connection portions 30 and the second electrical connection portions 40 are adjusted according to the operating mode of the electronic device to flexibly adjust the physical length of the slot antenna, thereby achieving good radiation performance in multiple operating modes. The movement of the first electrical connection units 31, the movement of the second electrical connection units 41, or both can be controlled simultaneously to flexibly adjust the electrical connection positions.

[0097] In an embodiment of the present disclosure, a plurality of first electrical connection units 31 are spaced apart on the first body 10, and a plurality of second electrical connection units 41 are spaced apart on the second body 20. In the folded state, the electrical connection position is adjusted by controlling the contact between the first electrical connection units 31 and the second electrical connection units 41 at different positions, thereby achieving flexible adjustment of the physical length of the slot antenna, so that the electronic device can have good radiation performance in multiple operating modes.

[0098] In the embodiments of the present disclosure, Figure 2 、 Figure 3 and Figures 6A-6H As shown, the first body 10 includes a first side portion 11 and a second side portion 12 opposite each other. The first side portion 11 extends in a direction perpendicular to the rotation axis, and the first electrical connection unit 31 is disposed near the first side portion 11 and / or the second side portion 12. The second body 20 includes a third side portion 21 and a fourth side portion 22 opposite each other. The third side portion 21 and the fourth side portion 22 extend in directions perpendicular to the rotation axis, and the second electrical connection unit 41 is disposed near the third side portion 21 and / or the fourth side portion 22. In the folded state, at least one first electrical connection unit 31 near the first side portion 11 and at least one second electrical connection unit 41 near the third side portion 21 are electrically connected; and / or at least one first electrical connection unit 31 near the second side portion 12 and at least one second electrical connection unit 41 near the fourth side portion 22 are electrically connected.

[0099] For example, a vertically foldable electronic device is used. The length of the first body 10 is perpendicular to the rotation axis, while the width is parallel to the rotation axis. Along the width of the first body 10, the first body 10 includes a first side portion 11 and a second side portion 12, opposing each other. The end of the first body 10 distal from the rotation mechanism is a first end portion 13. The first side portion 11 and the second side portion 12 are perpendicular to the rotation axis, with perpendicularity encompassing both absolute and approximate perpendicularity.

[0100] The second body 20 has a length perpendicular to the rotation axis and a width parallel to the rotation axis. Along its width, the second body 20 includes a third side portion 21 and a fourth side portion 22, each of which is opposed to the rotation mechanism. The end of the second body 20 distal to the rotation mechanism is a second end portion 23. The third side portion 21 and the fourth side portion 22 are perpendicular to the rotation axis, where perpendicularity includes both absolute and approximately perpendicularity. The first side portion 11 and the third side portion 21 are located on the same side of the electronic device, and the second side portion 12 and the fourth side portion 22 are also located on the same side of the electronic device.

[0101] In some embodiments, multiple first electrical connection units 31 are disposed near the first side portion 11, and multiple second electrical connection units 41 are disposed near the third side portion 21. In the folded state, at least one first electrical connection unit 31 near the first side portion 11 and at least one second electrical connection unit 41 near the third side portion 21 can be controlled to be electrically connected based on the operating mode of the electronic device. For example, the first electrical connection unit 31 and the second electrical connection unit 41 at the first position are electrically connected.

[0102] In some embodiments, multiple first electrical connection units 31 are disposed near the second side portion 12, and multiple second electrical connection units 41 are disposed near the fourth side portion 22. In the folded state, at least one first electrical connection unit 31 near the second side portion 12 and at least one second electrical connection unit 41 near the fourth side portion 22 can be controlled to be electrically connected based on the operating mode of the electronic device. For example, the first electrical connection unit 31 and the second electrical connection unit 41 at the first position are electrically connected.

[0103] like Figure 2 and Figure 3 As shown, in some embodiments, multiple first electrical connection units 31 are arranged near the first side portion 11, multiple second electrical connection units 41 are arranged near the third side portion 21, and multiple first electrical connection units 31 are arranged near the second side portion 12, and multiple second electrical connection units 41 are arranged near the fourth side portion 22. Figures 6B to 6H As shown, in the folded state, at least one first electrical connection unit 31 near the first side 11 and at least one second electrical connection unit 41 near the third side 21 can be controlled to be electrically connected, as can at least one first electrical connection unit 31 near the second side 12 and at least one second electrical connection unit 41 near the fourth side 22.

[0104] It is understood that the number of first electrical connection units 31 near the first side 11 and the number of first electrical connection units 31 near the second side 12 may be the same or different. In some embodiments, the multiple first electrical connection units 31 near the first side 11 and the multiple first electrical connection units 31 near the second side 12 may be symmetrically arranged with respect to the central plane of the first body 10. In some embodiments, the multiple first electrical connection units 31 near the first side 11 and the multiple first electrical connection units 31 near the second side 12 may be staggered along the length of the first body 10.

[0105] It is understood that the number of second electrical connection units 41 near the third side 21 and the number of second electrical connection units 41 near the fourth side 22 may be the same or different. In some embodiments, the multiple second electrical connection units 41 near the third side 21 and the multiple second electrical connection units 41 near the fourth side 22 may be symmetrically arranged with respect to the central plane of the second body 20. In some embodiments, the multiple second electrical connection units 41 near the third side 21 and the multiple second electrical connection units 41 near the fourth side 22 may be staggered along the length direction of the second body 20.

[0106] The number and position of the first electrical connection units 31 can be flexibly adjusted according to the internal space of the first body 10, and the number and position of the second electrical connection units 41 can be flexibly adjusted according to the internal space of the second body 20. It is sufficient to ensure that the first electrical connection units 31 on the first body 10 and the second electrical connection units 41 on the second body 20 are in contact with each other in the folded state.

[0107] The first electrical connection unit 31 is close to the first side 11 and / or the second side 12 of the first body 10, and the second electrical connection unit 41 is close to the third side 21 and / or the fourth side 22 of the second body 20, which can reduce the impact on the display screen, avoid occupying the installation space of the display screen, and ensure that the screen size of the display screen is maximized.

[0108] In an embodiment of the present disclosure, a plurality of first electrical connection units 31 are arranged near the first side portion 11 and / or the second side portion 12, and a plurality of second electrical connection units 41 are arranged near the third side portion 21 and / or the fourth side portion 22. The positions and quantities of the first electrical connection units 31 and the second electrical connection units 41 can be flexibly set according to the internal space of the electronic device. In the folded state, it is beneficial to further enhance the flexible adjustment of the physical length of the slot antenna. In addition, it occupies little space and reduces the impact on the display screen.

[0109] In the embodiments of the present disclosure, Figure 8A 、 Figure 8B and Figure 8CAs shown, the first electrical connection unit 31 is connected to the first body 10 via an elastic connector 50, and / or the second electrical connection unit 41 is connected to the second body 20 via an elastic connector 50. The elastic connector 50 is configured to switch between a first deformation state and a second deformation state. When the elastic connector 50 is in the first deformation state, the first electrical connection unit 31 and the second electrical connection unit 41 are separated; when the elastic connector 50 is in the second deformation state, at least one first electrical connection unit 31 and at least one second electrical connection unit 41 are in contact.

[0110] The elastic connector 50 includes a spring, a spring, a tension spring, etc. For example, the elastic connector 50 is a spring that can switch between a first deformation state and a second deformation state. In the first deformation state, the spring can be in a natural state or a compressed state; in the second deformation state, the spring can be in a natural state or a tensioned state. The expansion and contraction direction of the spring is perpendicular to the first body 10 or the second body 20. For example, in the first deformation state, the spring is in a natural state, and there is a gap between the first electrical connection unit 31 and the second electrical connection unit 41, that is, the first electrical connection unit 31 and the second electrical connection unit 41 are in a phase-separated state. When switching from the first deformation state to the second deformation state, the spring stretches, and the expansion and contraction of the spring causes the first electrical connection unit 31 and the second electrical connection unit 41 to contact each other, thereby achieving electrical connection between the two. When switching from the second deformation state to the first deformation state, the spring shortens, causing the first electrical connection unit 31 and the second electrical connection unit 41 to separate.

[0111] like Figure 8A As shown, in some embodiments, the first electrical connection unit 31 is connected to the first body 10 via an elastic connector 50, which is capable of expanding and contracting in a direction perpendicular to the thickness of the first body 10. During the transition from the first deformed state to the second deformed state, the first electrical connection unit 31 can move toward the second electrical connection unit 41 as the elastic connector 50 expands, until the two electrical connection units 41 come into contact. During the transition from the second deformed state to the first deformed state, the first electrical connection unit 31 can move away from the second electrical connection unit 41 as the elastic connector 50 contracts, until the two electrical connection units 41 separate.

[0112] like Figure 8BAs shown, in some embodiments, the second electrical connection unit 41 is connected to the second body 20 via an elastic connector 50, which is capable of expanding and contracting in a direction perpendicular to the thickness of the second body 20. During the transition from the first deformed state to the second deformed state, the second electrical connection unit 41 can move toward the first electrical connection unit 31 as the elastic connector 50 expands, until the first electrical connection unit 31 and the second electrical connection unit 31 come into contact. During the transition from the second deformed state to the first deformed state, the second electrical connection unit 41 can move away from the first electrical connection unit 31 as the elastic connector 50 contracts, until the first electrical connection unit 31 and the second electrical connection unit 31 separate.

[0113] like Figure 8C As shown, in some embodiments, the first electrical connection unit 31 is connected to the first body 10 via an elastic connector, defined as a first elastic connector 51, which is capable of expanding and contracting in a direction perpendicular to the thickness of the first body 10. Simultaneously, the second electrical connection unit 41 is connected to the second body 20 via an elastic connector, defined as a second elastic connector 52, which is capable of expanding and contracting in a direction perpendicular to the thickness of the second body 20. During the transition from the first deformed state to the second deformed state, the first electrical connection unit 31 moves toward the second electrical connection unit 41 as the first elastic connector 51 extends. Simultaneously, the second electrical connection unit 41 moves toward the first electrical connection unit 31 as the second elastic connector 52 extends, until the first and second electrical connection units 31 and 41 come into contact. During the transition from the second deformed state to the first deformed state, the first and second electrical connection units 31 and 41 move away from each other as the first and second elastic connectors 51 and 52 contract, until they separate.

[0114] The elastic connector 50, the first electrical connection unit 31, and the second electrical connection unit 41 only occupy the vertical space of the electronic device, thus occupying a small amount of space. The elastic connector 50 can be extended or retracted to allow the first electrical connection unit 31 and the second electrical connection unit 41 to contact or separate, eliminating the need for a complex drive mechanism. This also facilitates the rapid switching of the first electrical connection unit 31 and the second electrical connection unit 41 between an electrically connected state and a non-electrically connected state.

[0115] In an embodiment of the present disclosure, the first electrical connection unit 31 is connected to the first body 10 through an elastic connection member 50 and / or the second electrical connection unit 41 is connected to the second body 20 through an elastic connection member 50. Through the expansion and contraction of the elastic connection member 50, the first electrical connection unit 31 and the second electrical connection unit 41 are electrically connected or separated, which occupies a small space, has a simple structure, and is conducive to rapid switching between an electrically connected state and a non-electrically connected state.

[0116] In the embodiments of the present disclosure, Figure 5C 、 Figure 8A 、 Figure 8B and Figure 8C As shown, when the elastic connector 50 is in the first deformation state, at least a portion of the first electrical connection unit 31 connected to the elastic connector 50 is located in the first body 10; and / or when the elastic connector 50 is in the first deformation state, at least a portion of the second electrical connection unit 41 connected to the elastic connector 50 is located in the second body 20.

[0117] like Figure 5C and Figure 8A As shown, in some embodiments, the first electrical connection unit 31 is connected to the first middle frame of the first body 10 via an elastic connector 50, and the second electrical connection unit 41 is fixedly connected to the second middle frame of the second body 20. The end surface of the second electrical connection unit 41 is flush with or slightly higher than the second surface 200 of the second body 20. When the elastic connector 50 is in the first deformed state, at least a portion of the first electrical connection unit 31 is located within the first body 10, that is, a portion of the first electrical connection unit 31 is located within the first body 10, or the entire first electrical connection unit 31 is located within the first body 10. In the expanded state, the end surface of the first electrical connection unit 31 is flush with or slightly higher than the first surface 100 of the first body 10, and the end surface of the second electrical connection unit 41 is flush with or slightly higher than the second surface 200 of the second body 20, thereby improving the aesthetics of the electronic device.

[0118] like Figure 5C and Figure 8B As shown, in some embodiments, the second electrical connection unit 41 is connected to the second middle frame of the second body 20 via an elastic connector 50, and the first electrical connection unit 31 is fixedly connected to the first middle frame of the first body 10. The end surface of the first electrical connection unit 31 is flush with or slightly higher than the first surface 100 of the first body 10. When the elastic connector 50 is in the first deformed state, at least a portion of the second electrical connection unit 41 is located within the second body 20, that is, a portion of the second electrical connection unit 41 is located within the second body 20, or the entire second electrical connection unit 41 is located within the second body 20. In the expanded state, the end surface of the first electrical connection unit 31 is flush with or slightly higher than the first surface 100 of the first body 10, and the end surface of the second electrical connection unit 41 is flush with or slightly higher than the second surface 200 of the second body 20, thereby improving the aesthetics of the electronic device.

[0119] like Figure 5C and Figure 8CAs shown, in some embodiments, the first electrical connection unit 31 is connected to the first middle frame of the first body 10 via a first elastic connector 51, and the second electrical connection unit 41 is connected to the second middle frame of the second body 20 via a second elastic connector 52. When the first elastic connector 51 is in a first deformed state, at least a portion of the first electrical connection unit 31 is located within the first body 10, that is, a portion of the first electrical connection unit 31 is located within the first body 10, or the first electrical connection unit 31 is located entirely within the first body 10. When the second elastic connector 52 is in the first deformed state, at least a portion of the second electrical connection unit 41 is located within the second body 20, that is, a portion of the second electrical connection unit 41 is located within the second body 20, or the second electrical connection unit 41 is located entirely within the second body 20. In the expanded state, the end surface of the first electrical connection unit 31 is flush with or slightly above the first surface 100 of the first body 10, and the end surface of the second electrical connection unit 41 is flush with or slightly above the second surface 200 of the second body 20, effectively improving the aesthetics of the electronic device.

[0120] In the embodiment of the present disclosure, when the elastic connector 50 is in the first deformed state, at least a portion of the first electrical connection unit 31 connected to the elastic connector 50 is located within the first body 10 and / or at least a portion of the second electrical connection unit 41 connected to the elastic connector 50 is located within the second body 20. When the electronic device is in the unfolded state, the end surface of the first electrical connection unit 31 is flush with or slightly higher than the first surface 100 of the first body 10, and the end surface of the second electrical connection unit 41 is flush with or slightly higher than the second surface 200 of the second body 20, effectively improving the aesthetics of the electronic device.

[0121] In an embodiment of the present disclosure, the first electrical connection unit 31 includes a first magnetic conductive member; and / or the second electrical connection unit 41 includes a second magnetic conductive member.

[0122] like Figure 8AAs shown, in some embodiments, the second electrical connection unit 41 can be a second magnetic conductive member, and the second magnetic conductive member can be an electromagnet, and the magnetism of the electromagnet can be controlled by turning the circuit on and off. For example, a second circuit is provided in the second body 20, and when the second circuit is turned on, the electromagnet generates magnetism and attracts the corresponding first electrical connection unit 31, so that the elastic connection member 50 connected to the first electrical connection unit 31 is stretched, and the elastic connection member 50 switches from the first deformation state to the second deformation state until the first electrical connection unit 31 and the second electrical connection unit 41 are in contact. When the second circuit is disconnected, the magnetism of the electromagnet disappears, and the elastic connection member 50 retracts, switching from the second deformation state to the first deformation state until the first electrical connection unit 31 and the second electrical connection unit 41 are separated. It can be understood that each second magnetic conductive member is provided with a corresponding second circuit for controlling magnetism.

[0123] like Figure 8B As shown, in some embodiments, the first electrical connection unit 31 can be a first magnetic conductive member, and the first magnetic conductive member can be an electromagnet, and the magnetism of the electromagnet can be controlled by turning the circuit on and off. For example, a first circuit is provided in the first body 10, and when the first circuit is turned on, the electromagnet generates magnetism and attracts the corresponding second electrical connection unit 41, so that the elastic connection member 50 connected to the second electrical connection unit 41 is stretched, and the elastic connection member 50 switches from the first deformation state to the second deformation state until the first electrical connection unit 31 and the second electrical connection unit 41 are in contact. When the first circuit is disconnected, the magnetism of the electromagnet disappears, and the elastic connection member 50 retracts and switches from the second deformation state to the first deformation state until the first electrical connection unit 31 and the second electrical connection unit 41 are separated. It can be understood that each first magnetic conductive member is provided with a corresponding first circuit for controlling magnetism.

[0124] like Figure 8CAs shown, in some embodiments, the first electrical connection unit 31 is connected to the first middle frame of the first body 10 via a first elastic connector 51. The first electrical connection unit 31 may be a first magnetic conductive member, such as an electromagnet. The first body 10 is provided with a first circuit, and the magnetism of the electromagnet can be controlled by turning the first circuit on and off. The second electrical connection unit 41 is connected to the second middle frame of the second body 20 via a second elastic connector 52. The second electrical connection unit 41 may be a second magnetic conductive member, such as an electromagnet. The second body 20 is provided with a second circuit, and the magnetism of the electromagnet can be controlled by turning the second circuit on and off. When the first and second circuits are connected, the two electromagnets generate magnetism that attracts the first and second electrical connection units 31 and 41, causing the first elastic connector 51 connected to the first electrical connection unit 31 and the second elastic connector 52 connected to the second electrical connection unit 41 to stretch. The two elastic connectors 50 switch from the first deformation state to the second deformation state until the first and second electrical connection units 31 and 41 come into contact. The first circuit and the second circuit are disconnected, the magnetism of the electromagnet disappears, the first elastic connector 51 and the second elastic connector 52 retract, and the second deformation state switches to the first deformation state until the first electrical connection unit 31 and the second electrical connection unit 41 are separated.

[0125] By controlling the magnetism of the first or second magnetic conductive member through the on / off circuit, the elastic connector 50 is controlled to switch between the first and second deformation states, thereby facilitating the rapid contact and separation of the first and second electrical connection units 31, 41. Furthermore, the magnetic connection between the first and second electrical connection units 31, 41 is less susceptible to separation due to external factors such as shaking, thereby improving the reliability of the electrical connection between the first and second electrical connection units 31, 41 when connected.

[0126] In the embodiment of the present disclosure, the first electrical connection unit 31 and the second electrical connection unit 41 are electrically connected through magnetism, and are not easily separated due to external factors such as shaking, which is beneficial to improving the reliability of the electrical connection between the first electrical connection unit 31 and the second electrical connection unit 41 in the electrically connected state; in addition, the magnetism of the first magnetic conductive component and / or the second magnetic conductive component is controlled by the on-off switching of the circuit, which is beneficial to the rapid contact or separation of the first electrical connection unit 31 and the second electrical connection unit 41.

[0127] In the embodiment of the present disclosure, the first electrical connection unit 31 is connected to the first body 10, or the second electrical connection unit 41 is connected to the second body 20 via a movable connection member, and the movable connection member is configured to be switchable between a first position and a second position. In the first position, the first electrical connection unit 31 and the second electrical connection unit 41 are offset so as to separate the first electrical connection unit 31 and the second electrical connection unit 41; in the second position, the first electrical connection unit 31 and the second electrical connection unit 41 are in contact so as to electrically connect the first electrical connection unit 31 and the second electrical connection unit 41.

[0128] In some embodiments, the movable connection member may include a rotating shaft and a connecting rod. For example, one end of the connecting rod is connected to the rotating shaft, and the other end of the connecting rod is connected to the first electrical connection unit 31. The rotation of the rotating shaft drives the connecting rod to swing, and then drives the first electrical connection unit 31 to swing. In the first position, the connecting rod is in a horizontal state, and the first electrical connection unit 31 and the second electrical connection unit 41 are misaligned, that is, the first electrical connection unit 31 and the second electrical connection unit 41 are separated. In the second position, the rotating shaft rotates to cause the connecting rod to swing to a vertical state, and the first electrical connection unit 31 and the second electrical connection unit 41 are in contact, thereby achieving electrical connection between the two. The second electrical connection unit 41 can also be connected to the second body 20 through a movable connection member, and the second electrical connection unit 41 and the first electrical connection unit 31 are in contact or separated by the rotation of the rotating shaft and the swinging of the connecting rod.

[0129] In some embodiments, the movable connector can be a screw-nut transmission mechanism, which includes a screw and a nut, wherein the nut is capable of linear motion along the axis of the screw. For example, the first electrical connection unit 31 is connected to the first body 10 via a movable connector. The screw is disposed within the first body 10, with the axis of the screw parallel to the length of the first body 10, and the first electrical connection unit 31 is connected to the nut. In the first position, the first electrical connection unit 31 and the second electrical connection unit 41 are misaligned. When the screw rotates forward, the nut moves along the axis of the screw, driving the first electrical connection unit 31 toward the second electrical connection unit 41 until the first electrical connection unit 31 moves relative to and contacts the second electrical connection unit 41, at which point the movable connector switches to the second position. Similarly, when the screw rotates backward, the nut moves along the axis of the screw, driving the first electrical connection unit 31 toward and away from the second electrical connection unit 41 until the first electrical connection unit 31 moves completely away from the second electrical connection unit 41, at which point the movable connector switches to the first position. Alternatively, the second electrical connection unit 41 may be connected to the second body 20 via a movable connection member, and the second electrical connection unit 41 and the first electrical connection unit 31 may be brought into contact with or separated from each other by rotating the screw rod and moving the nut.

[0130] In an embodiment of the present disclosure, the first electrical connection unit 31 is connected to the first body 10 through a movable connection part, or the second electrical connection unit 41 is connected to the second body 20 through a movable connection part. The movable connection part can realize the contact or separation of the first electrical connection unit 31 and the second electrical connection unit 41 through rotation, swinging, linear motion, etc.

[0131] In the embodiments of the present disclosure, Figure 2 、 Figure 3 、 Figure 4 9 , the first body 10 includes a first housing 14, components located within the first housing 14, and a first portion of a display screen. The second body 20 includes a second housing 24, components located within the second housing 24, and a second portion of a display screen.

[0132] In some embodiments, the electronic device may be a vertically folding electronic device, including a vertically folding mobile phone, which may have a display screen. The first body 10 includes a first housing 14, components mounted within the first housing 14, and a first portion of the display screen.
