In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] An embodiment of the present application provides an antenna structure.

[0022] Please refer to Figures 1 to 3 The antenna structure provided in one embodiment of the present application includes a first movable part 204, a second movable part 205 and at least two dipole antennas, wherein the at least two dipole antennas include a first dipole antenna 211 and a second dipole antenna 212; the first movable part 204 is provided with a receiving cavity, wherein the at least two dipole antennas are received in the receiving cavity, and the at least two dipole antennas are spaced apart along a first direction; the second movable part 205 is sleeved outside the first movable part 204, and the dielectric constant of the first movable part 204 is different from the dielectric constant of the second movable part 205.

[0023] In which, one of the first movable part 204 and the second movable part 205 can move in the first direction relative to the other, so that the second movable part 205 can move between the first position and the second position of the first movable part 204; when the second movable part 205 moves to the first position, the first dipole antenna 211 is located within the inclusion range of the second movable part 205, and the second dipole antenna 212 is located outside the inclusion range of the second movable part 205; when the second movable part 205 moves to the second position, the second dipole antenna 212 is located within the inclusion range of the second movable part 205, and the first dipole antenna 211 is located outside the inclusion range of the second movable part 205.

[0024] The antenna structure provided in the embodiment of the present application can be applied to electronic devices such as mobile phones and tablet computers. Optionally, the movement of the first movable member 204 or the second movable member 205 can be driven by a separate driving mechanism, for example, a slide groove is provided on the first movable member 204, and a slide rail is provided on the second movable member 205, and the driving mechanism is connected to the second movable member 205 to drive the second movable member 205 to move relative to the first movable member 204. Alternatively, the first movable member 204 is a transmission shaft, the second movable member 205 is threadedly connected to the first movable member 204 and sleeved outside the first movable member 204, and the motor is connected to the first movable member 204 to drive the first movable member 204 to rotate, and the rotation of the first movable member 204 drives the second movable member 205 to move. Of course, the first movable member 204 and the second movable member 205 can also be other structural forms, which are not listed in detail in this application.

[0025] Among them, the dipole antenna has omnidirectional radiation characteristics and good gain effect, and can be better applied to electronic devices with complex structures. It should be noted that the antenna operating wavelength is inversely proportional to the relative dielectric constant. The greater the dielectric loading, the greater the relative dielectric constant, the shorter the wavelength required for the antenna, and the shorter the corresponding physical size required. Effective use of the dielectric constant of the medium can change the antenna's operating wavelength, so that the antenna can change its operating frequency band.

[0026] In the embodiment of the present application, at least two dipole antennas are accommodated in the receiving cavity of the first movable member 204, and the second movable member 205 can move between the first position and the second position of the first movable member 204, so that the second movable member 205 can move to correspond to different dipole antennas in the first movable member 204.

[0027] For example, the first dipole antenna 211 is opposite to the first position of the first movable member 204, and the second dipole antenna 212 is opposite to the second position of the first movable member 204. Figure 1 As shown, when the second movable member 205 moves to the first position, the first dipole antenna 211 is located within the inclusion range of the second movable member 205, and the second dipole antenna 212 at the second position is also located outside the inclusion range of the second movable member 205. The dielectric constant of the first movable member 204 is different from the dielectric constant of the second movable member 205. When the second movable member 205 moves to the first position, the first movable member 204 and the second movable member 205 are simultaneously loaded on the first dipole antenna 211, while the second dipole antenna 212 is only loaded by the first movable member 204, which makes the working wavelengths of the first dipole antenna 211 and the second dipole antenna 212 different. For example, the first dipole antenna 211 works in the first frequency band, and the second dipole antenna 212 works in the second frequency band.

[0028] like Figure 2As shown, when the second movable part 205 moves to the second position, the first dipole antenna 211 is only loaded by the first movable part 204, and the second dipole antenna 212 is loaded by both the first movable part 204 and the second movable part 205. At this time, the operating wavelengths of the first dipole antenna 211 and the second dipole antenna 212 are changed or switched. For example, at this time, the first dipole antenna 211 operates in the second frequency band, and the second dipole antenna 212 operates in the first frequency band.

[0029] In the embodiment of the present application, by changing the position of the second movable part 205 on the first movable part 204, the operating wavelengths of the first dipole antenna 211 and the second dipole antenna 212 accommodated in the first movable part 204 can be changed, so that the first dipole antenna 211 and the second dipole antenna 212 can be switched between different operating frequency bands, so that the antenna structure can change the operating frequency band of the dipole antenna according to the usage scenario of the electronic device to ensure the antenna performance of the antenna structure in different scenarios; and, through the design of the first movable part 204 and the second movable part 205, the antenna structure can operate in at least two different frequency bands, without the need to separately set up antenna structures for two operating frequency bands, thereby effectively saving the internal space of the electronic device.

[0030] It should be noted that the first dipole antenna 211 may include at least one dipole antenna, and the second dipole antenna 212 may also include at least one dipole antenna; the first dipole antenna 211 and the second dipole antenna 212 are arranged at an interval.

[0031] In an optional implementation of the embodiment of the present application, the first movable member 204 is a rotating shaft, and the second movable member 205 is a sleeve, the sleeve is sleeved outside the rotating shaft, and the rotating shaft and the sleeve are threadedly connected. Optionally, the rotating shaft can be connected to a motor, the rotating shaft is provided with an external thread, and the sleeve is provided with an internal thread; when the motor drives the rotating shaft to rotate, the rotation of the rotating shaft can also drive the sleeve to rotate and move relative to the rotating shaft. For example, when the motor rotates forward, the rotating shaft rotates forward and drives the sleeve to move upward to the first position; when the motor rotates reversely, the rotating shaft rotates reversely and drives the sleeve to move downward to the second position; the sleeve can be driven to move between the first position and the second position through the forward and reverse rotation of the motor.

[0032] Please refer to Figure 1 and Figure 2 The antenna structure may further include a threaded mechanism 206, the threaded mechanism 206 is sleeved outside the first movable member 204 and is threadedly connected to the first movable member 204, and the second movable member 205 is sleeved outside the threaded mechanism 206 and is threadedly connected to the threaded mechanism 206. For example, the first movable member 204 is a rotating shaft, the second movable member 205 is a shaft sleeve, and the rotating shaft and the shaft sleeve are connected through the threaded mechanism 206.

[0033] The first movable member 204 may be connected to a driving mechanism, and the driving mechanism is used to drive the first movable member 204 to rotate, and then the rotation of the first movable member 204 can drive the thread mechanism 206 sleeved on the outside thereof to rotate, and the rotation of the thread mechanism 206 can drive the second movable member 205 to rotate. It can be understood that the driving mechanism drives the first movable member 204 to rotate forward or reverse, and finally drives the second movable member 205 to move between the first position and the second position through the transmission of the thread mechanism 206, so that the first dipole antenna 211 and the second dipole antenna 212 switch between different working frequency bands to ensure the antenna performance of the antenna structure in different scenarios.

[0034] In the embodiment of the present application, the at least two dipole antennas may further include a third dipole antenna 213, and the third dipole antenna 213 is located between the first dipole antenna 211 and the second dipole antenna 212. Figure 1 and Figure 2 When the second movable part 205 moves to the first position, the first dipole antenna 211 and the third dipole antenna 213 are located within the inclusion range of the second movable part 205, and the second dipole antenna 212 is located outside the inclusion range of the second movable part 205; when the second movable part 205 moves to the second position, the third dipole antenna 213 and the second dipole antenna 212 are located within the inclusion range of the second movable part 205, and the first dipole antenna 211 is located outside the inclusion range of the second movable part 205.

[0035] It should be noted that when the second movable part 205 moves to the first position and the first dipole antenna 211 and the third dipole antenna 213 are located within the inclusion range of the second movable part 205, the first dipole antenna 211 and the third dipole antenna 213 have the same operating frequency band, such as operating in the first frequency band, while the second dipole antenna 212 operates in the second frequency band; when the second movable part 205 moves to the second position and the third dipole antenna 213 and the second dipole antenna 212 are located within the inclusion range of the second movable part 205, the third dipole antenna 213 and the second dipole antenna 212 have the same operating frequency band, such as operating in the first frequency band, while the first dipole antenna 211 operates in the second frequency band. In this way, when the second movable member 205 moves between the first position and the second position, the third dipole antenna 213 is always located within the inclusion range of the second movable member 205, and thus at least two dipole antennas are always operating in the first frequency band, which can increase the radiation effect of the antenna in the first frequency band and ensure the antenna performance in the first frequency band. For example, the first frequency band may be a frequency band with a relatively high proportion of users.

[0036] Optionally, when the second movable part 205 moves to the first position, the operating frequency band of the first dipole antenna 211 is the N41 band, and the operating frequency band of the second dipole antenna 212 is the N78 band; when the second movable part 205 moves to the second position, the operating frequency band of the first dipole antenna 211 is the N78 band, and the operating frequency band of the second dipole antenna 212 is the N41 band.

[0037] Wherein, in the case where the at least two dipole antennas also include the third dipole antenna 213, when the second movable part 205 moves to the first position, the working frequency band of the first dipole antenna 211 and the third dipole antenna is the N41 frequency band, and the working frequency band of the second dipole antenna 212 is the N78 frequency band; when the second movable part 205 moves to the second position, the working frequency band of the first dipole antenna 211 is the N78 frequency band, and the working frequency band of the second dipole antenna 212 and the third dipole antenna 213 is the N41 frequency band. In this way, no matter whether the second movable part 205 is in the first position or the second position, at least two dipole antennas work in the N41 frequency band, so as to ensure the radiation effect of the antenna in the N41 frequency band, and also ensure that the electronic device has good antenna performance in the N41 frequency band, thereby improving the user experience.

[0038] In an optional implementation of the embodiment of the present application, the dielectric constant of the first movable member 204 is smaller than the dielectric constant of the second movable member 205. When the second movable member 205 is located at the first position, the first dipole antenna 211, or the first dipole antenna 211 and the third dipole antenna 213 are within the inclusive range of the second movable member 205 with a higher dielectric constant, that is, they are loaded with a high dielectric constant, and the resonance is biased toward a low frequency. At this time, the first dipole antenna 211, or the first dipole antenna 211 and the third dipole antenna 213 work in a first frequency band, such as the N41 frequency band; while the second dipole antenna 212 is not loaded with a high dielectric constant and works in a second frequency band, such as the N78 frequency band. When the second movable member 205 moves to the second position, the second dipole antenna 212, or the second dipole antenna 212 and the third dipole antenna 213 are within the range of the second movable member 205 with a higher dielectric constant, and work in the first frequency band, such as the N41 frequency band, while the first dipole antenna 211 works in the second frequency band, such as the N78 frequency band. In this way, by effectively utilizing the difference in dielectric constants between the first movable member 204 and the second movable member 205, the second movable member 205 moves, so that the dipole antenna can work in different working frequency bands, thereby ensuring the antenna performance of the antenna structure in different scenarios.

[0039] Optionally, the second movable member 205 can also be moved to a third position relative to the first movable member 204. When the second movable member 205 moves to the third position, the at least two dipole antennas are both located outside the inclusion range of the second movable member 205. In this case, the at least two dipole antennas can both operate in the second frequency band, such as the N78 frequency band. In this way, when the electronic device requires the antenna structure to operate in the N78 frequency band, the movement of the second movable member 205 can be controlled so that the at least two dipole antennas are both located outside the inclusion range of the second movable member 205, which means that the number of dipole antennas operating in the N78 frequency band is large, so as to ensure that the antenna structure has good antenna performance in this frequency band.

[0040] An embodiment of the present application also provides an electronic device.

[0041] Please refer to Figures 1 to 5 The electronic device includes a scroll screen 10 and the antenna structure described in the above embodiment, the scroll screen 10 is connected to the second movable member 205, the scroll screen 10 can switch between a first display area and a second display area, and the first display area is larger than the second display area; wherein, when the scroll screen 10 is the first display area (such as Figure 5 As shown), the second movable member 205 is located at the first position, and when the scroll screen 10 is in the second display area (as shown Figure 4 As shown), the second movable member 205 is located at the second position.

[0042] It should be noted that the electronic device provided in the embodiment of the present application includes all the technical features of the antenna structure in the above embodiment, and can achieve the technical effects that can be achieved by the above antenna structure. To avoid repetition, it will not be repeated here.

[0043] Optionally, the scroll screen 10 may be connected to a driving mechanism, and the driving mechanism drives the scroll screen 10 to switch between the first display area and the second display area, and the movement of the scroll screen 10 can also drive the second movable member 205 to move between the first position and the second position. Alternatively, the scroll screen 10 may be pulled to expand to the first display area and pushed to shrink to the second display area by the force applied by the user.

[0044] In the embodiment of the present application, one of the first movable member 204 and the second movable member 205 can move relative to the other. For example, taking the second movable member 205 moving relative to the first movable member 204 in the first direction as an example, the first movable member 204 can also be connected to a driving mechanism, and the driving mechanism is used to drive the first movable member 204 to rotate, so as to drive the second movable member 205 to reciprocate in the first direction, so as to move the second movable member 205 between the first position and the second position. The movement of the second movable member 205 and the extension and contraction of the scroll screen 10 can be driven by the same driving mechanism, or can be driven by different driving mechanisms respectively, so that when the scroll screen 10 is extended to the first display area, the second movable member 205 moves to the first position, and when the scroll screen 10 is contracted to the second display area, the second movable member 205 moves to the second position.

[0045] Optionally, when the first movable member 204 is a rotating shaft and the second movable member 205 is a shaft sleeve, the scroll screen 10 is wound on the shaft sleeve, and the scroll screen 10 switches between the first display area and the second display area to drive the shaft sleeve to rotate. For example, the rotating shaft is threadedly connected to the shaft sleeve, and the scroll screen 10 is wound on the outside of the shaft sleeve. When the scroll screen 10 is extended, it can drive the shaft sleeve to rotate forward, so that the shaft sleeve moves to the first position on the rotating shaft; when the scroll screen 10 is retracted, it can drive the shaft sleeve to rotate reversely, so that the shaft sleeve moves to the second position.

[0046] Optionally, the dielectric constant of the first movable member 204 is smaller than the dielectric constant of the second movable member 205, and the antenna structure may further include a third dipole antenna 213, which is located between the first dipole antenna 211 and the second dipole antenna 212. When the second movable member 205 moves to the first position, the scroll screen 10 extends to the first display area, at which time the first dipole antenna 211 and the third dipole antenna 213 are located within the inclusion range of the second movable member 205, that is, they are loaded by the second movable member 205 with a higher dielectric constant, and the resonance is biased toward a low frequency. At this time, the first dipole antenna 211 and the third dipole antenna 213 operate in a first frequency band, such as the N41 frequency band; and the second dipole antenna 212 is loaded by the first movable member 204 with a lower dielectric constant, and operates in a second frequency band, such as the N78 frequency band. Among them, when the scroll screen 10 is unfolded, it is mostly used in scenarios such as gaming or video playback, and the proportion of users in the N41 frequency band is relatively high. Therefore, when the scroll screen 10 is unfolded to the first display area, the second movable part 205 accordingly moves to the first position, so that the first dipole antenna 211 and the third dipole antenna 213 are both located within the inclusion range of the second movable part 205 with a higher dielectric constant, so as to operate in the N41 frequency band. This can ensure that when the scroll screen 10 is unfolded, the antenna structure of the electronic device has better radiation effect and antenna performance in the N41 frequency band where the proportion of users is relatively high, so as to avoid freezes or delays in the electronic device during gaming or video playback, and provide users with a better user experience.

[0047] When the second movable part 205 moves to the second position, the third dipole antenna 213 and the second dipole antenna 212 are located within the inclusion range of the second movable part 205 with a higher dielectric constant, and operate in the N41 frequency band; the first dipole antenna 211 is located outside the inclusion range of the second movable part 205, and operates in the N78 frequency band; at this time, the scroll screen 10 shrinks to the second display area, thereby ensuring that when the scroll screen 10 of the electronic device is shrunk, the antenna structure also has good antenna radiation performance in the N41 frequency band, thereby ensuring the user experience.

[0048] Please refer to Figure 4 and Figure 5 The electronic device further includes a side frame 20 in the height direction, and a first frame 30 and a second frame 40 in the length direction, and the first frame 30 and the second frame 40 are respectively connected to both ends of the side frame 20. When the scroll screen 10 is extended to the first display area, the first frame 30 further includes an extended first extension portion 301, and the second frame 40 further includes an extended second extension portion 401. The connection relationship and the extension principle between the first frame 30 and the first extension portion 301, and the connection relationship and the extension principle between the second frame 40 and the second extension portion 401 can be referred to the relevant technology, and this application will not be described in detail.

[0049] In the embodiment of the present application, the side frame 20 is provided with the above antenna structure, wherein the first dipole antenna 211 is closer to the top of the electronic device in the height direction than the second dipole antenna 212, that is, closer to the second frame 40. For example, taking the electronic device as a mobile phone as an example, in the height direction of the mobile phone, the first dipole antenna 211 is closer to the top than the second dipole antenna 212. Based on the habit of most users using mobile phones, when a person holds the mobile phone, the second dipole antenna 212 is closer to the bottom and is easily held by the user's hand, and its antenna performance is easily affected by the coverage of the user's hand. As described above, when the scroll screen 10 is unfolded, it is mostly used in scenarios such as gaming or video playback. When the scroll screen 10 is unfolded to the first display area, the second movable part 205 moves to the first position, and the first dipole antenna 211 is located within the inclusion range of the second movable part 205 and operates in the N41 frequency band. The first dipole antenna 211 is closer to the top of the electronic device and is less affected by the user holding the electronic device. This ensures the antenna performance of the electronic device in the N41 frequency band, protects the user's gaming and video viewing experience, and improves the user experience of the electronic device.

[0050] Optionally, the electronic device includes but is not limited to a mobile phone, a tablet computer, a smart wearable device, etc.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
