Background

An antenna is built in an electronic device (such as a mobile terminal of a mobile phone, a tablet computer and the like) to realize a communication function. The performance of the built-in antenna is often degraded due to the shielding effect of the electronic device housing, which affects the normal communication of the user. Moreover, electronic devices are becoming thinner and lighter, and the internal structural space is becoming more and more tight, which compresses the clearance area of the antenna and causes interference to the antenna.

An electronic device includes a housing and an antenna assembly; the shell is provided with a containing space for containing the antenna assembly; the antenna assembly comprises a support and an antenna arranged on the support, an auxiliary circuit board is further arranged on the support, a first feed source is distributed on the auxiliary circuit board, and the first feed source is electrically connected with the antenna; the support is movably connected with the shell, the support can drive the antenna to move out of the accommodating space or retract into the accommodating space, and the antenna is electrically connected with the first feed source when moving out of the accommodating space.

A control method of an electronic apparatus for controlling the electronic apparatus described above, the control method comprising: providing a first driving force to enable the support in the electronic equipment to drive the antenna to move out of the accommodating space; and providing a second driving force to enable the support in the electronic equipment to drive the antenna to retract into the accommodating space.

In the scheme of the invention, the support can drive the antenna to move out of the accommodating space, and the design can reduce the shielding and shielding effect of the shell on the antenna and increase the clearance area of the antenna; when the antenna moves out of the accommodating space, the antenna is electrically connected with the first feed source on the support so as to realize the functions of radiating and receiving electromagnetic waves.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention.

The embodiment of the invention provides electronic equipment, which comprises but is not limited to mobile terminals such as mobile phones and tablet computers, and can also be other terminal equipment. The terminal device of the present embodiment includes, but is not limited to, an apparatus configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; a Personal Digital Assistant (PDA) that may include a radiotelephone, pager, internet/intranet access, Web browser, notepad, calendar, and/or a Global Positioning System (GPS) receiver; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver.

As shown in fig. 1, an electronic device 10 according to an embodiment of the present invention includes a housing 11 and an antenna assembly, and the housing 11 has a housing space for housing the antenna assembly. Wherein, a display screen 12 can be installed on the housing 11. The housing 11 may include a bezel 112 (a portion of the housing 11 adjacent to the display 12 in fig. 1) and a back plate 111 (a portion of the housing 11 adjacent to the bezel 112 and opposite to the display 12 in fig. 1, only shown in line in the view of fig. 1), and the bezel 112 and the back plate 111 may be of an integral or separate assembly type structure. The housing 11 may further include a middle frame, which is installed in the accommodating space and located between the display screen 12 and the back plate 111, and plays a role of supporting the display screen 12.

In this embodiment, the frame 112 is disposed around the outer periphery of the back plate 111 to form an accommodation space, that is, the accommodation space is a cavity surrounded by the inner surface of the housing 11 (that is, the accommodation space is an inner cavity that cannot be directly observed); in other embodiments, the receiving space may be a structural space enclosed between several parts of the housing 11 and capable of being directly observed. For example, the middle frame may extend beyond the back plate 111 in a direction parallel to the display 12, and an area surrounded by a portion of the middle frame extending beyond the back plate 111 and the back plate 111 serves as a receiving space, and the support 13 may be disposed in the area to substantially fill the area (i.e., the support 13 and the back plate 111 together constitute a "back surface" of the electronic device 10).

In this embodiment, the accommodating space has an opening a communicating with the outside. Preferably, the opening a is formed only in the frame 112. In other embodiments, the opening a may also be formed on the bezel 112 and the back plate 111 at the same time, or only on the back plate 111.

As shown in fig. 1 and 2, the antenna assembly may include a support 13 and an antenna 14 disposed on the support 13. Wherein, the support 13 is movably connected with the housing 11, including but not limited to sliding connection and rotating connection. A sub circuit board 15 is further mounted on the support 13, a first feed 16 is disposed on the sub circuit board 15, and the first feed 16 is used for feeding an excitation signal to the antenna 14 so that the antenna 14 radiates an electromagnetic wave signal.

In this embodiment, the antenna 14 may be made of any material and using any process type, such as a conductive material layer formed on the support 13 (e.g., formed on the surface of the support 13) and manufactured by an LDS (laser direct structuring) or PDS (direct print structuring) process; or the antenna 14 is a flexible circuit board arranged on the surface of the support 13, that is, the antenna 14 is an FPC antenna; alternatively, the antenna 14 may also be a bezel 112 antenna, i.e. using a conductive frame on the support 13 as an antenna. Wherein the conductive frame may be provided as part of the support 13 or assembled to the support 13 as a separate component.

In this embodiment, the antenna 14 may be an antenna having any working frequency band and function type, including but not limited to a 2G antenna, a 3G antenna, a 4G antenna, a 5G antenna, and the like, and also not limited to a BT antenna, a GPS antenna, a WIFI antenna, a GSM antenna, an LTE antenna, a millimeter wave antenna, and the like. The number of the antennas 14 is not limited to one, and may be two or more.

As shown in fig. 1 and fig. 2, the support 13 can bring the antenna 14 to move (including but not limited to, move in a sliding manner and move in a rotating manner) out of the accommodating space through the opening a, and at this time, the antenna 14 will be far away from the housing 11; alternatively, the support 13 may bring the antenna 14 to retract into the containing space from the opening a again. When the opening a is formed only on the frame 112, or both the frame 112 and the back plate 111, the moving direction of the support 13 and the antenna 14 may be substantially parallel to the display 12; when the opening a is formed only on the back plate 111, the moving direction of the support 13 and the antenna 14 may be substantially perpendicular to the display 12. Further, in order to shield and protect the internal structure of the support 13 and the antenna 14, a shield may be provided on the support 13, and the shield covers the antenna 14 and is removed together with the antenna 14.

In this embodiment, when the antenna 14 moves out of the accommodating space, the distance between the housing 11 and the antenna 14 is increased, so that the shielding and shielding effects of the housing 11 on the antenna 14 are weakened, and the signal quality of the antenna 14 is improved; and the headroom increases as the antenna 14 moves out, thereby optimizing antenna 14 performance. The support 13 can be controlled to drive the antenna 14 to move out of the accommodating space according to requirements so as to obtain better communication quality, or the support 13 can be controlled to drive the antenna 14 to move into the accommodating space so as to achieve the purpose of portability.

In this embodiment, the antenna 14 is electrically connected to the first feed 16 when moving out of the accommodating space, so as to receive the excitation signal of the first feed 16 and radiate the electromagnetic wave signal. Since the antenna 14 and the first feed 16 are both located on the support 13, i.e. the feed is located at a short distance from the antenna feed point, the loss of the antenna signal power is low, the efficiency of the antenna is high, and the sensitivity of the antenna is high.

Further, as shown in fig. 3, in the first embodiment of the present embodiment, when the antenna 14 is in the accommodating space, the antenna 14 is still electrically connected to the first feed 16. I.e., the antenna 14 receives an excitation signal from the first feed 16 at any position of the travel, thereby keeping the antenna feed to the feed at a close distance at all times.

Alternatively, as shown in fig. 4 and 5, in a second embodiment of this embodiment, the electronic device may further include a main circuit board 17 disposed in the housing, and the main circuit board 17 is disposed with a second feed 18. The second feed 18 may be a different feed than the first feed 16 ("different" including but not limited to meaning different supported frequency bands, different types, different powers, etc.) or may be the same feed. When the antenna 14 is in the accommodating space, the antenna 14 is electrically connected with the second feed 18. When moved out of the receiving space, the antenna 14 is electrically disconnected from the second feed 18 and electrically connected to the first feed 16. That is, in the present second embodiment, different feeds can be switched to be electrically connected to the antenna 14 at different positions of the antenna 14.

The design of the second embodiment described above applies to: for the case that the second feed 18 and the first feed 16 are the same feed, when the antenna 14 is located in the accommodating space, the distance from the second feed 18 to the feed point of the antenna 14 is closer than the distance from the first feed 16 to the feed point of the antenna 14, and then the antenna 14 is electrically connected with the second feed 18, which is beneficial to reducing the loss of the antenna signal power; when the antenna 14 is located outside the housing space, the second feed 18 is farther away from the feed point of the antenna 14 than the first feed 16 is, and the antenna 14 is switched to be electrically connected with the first feed 16, which is beneficial to reducing the loss of the antenna signal power.

The design of the second embodiment described above is also applicable to: when the antenna 14 is inside or outside the housing space, the antenna 14 is electrically connected to the second feed 18 and the first feed 16, thereby achieving different communication effects. For example, the power of the first feed 16 may be less than the power of the second feed 18. When the antenna 14 is in the accommodating space, because the shielding effect of the housing 11 on the antenna 14 is large, the antenna 14 can be electrically connected with the second feed 18 with large power at this time, so as to improve the signal strength of the antenna. When the antenna 14 moves to the accommodating space, the shielding effect of the housing 11 on the antenna 14 is reduced, and the antenna 14 can be electrically connected with the first feed 16 with smaller power, so as to save the power consumption of the electronic device 10 while radiating the antenna signal with designed strength. Alternatively, the type of first feed 16 (e.g., an NFC chip) may be different from the type of second feed 18 (e.g., a GPS chip). When the antenna is in the accommodating space, the antenna 14 can be electrically connected with the GPS chip, so that the antenna 14 is used as a GPS antenna; when the antenna is outside the housing space, the antenna 14 may be electrically connected to the NFC chip, and thus the antenna 14 functions as an NFC antenna.

As shown in fig. 6, in the second embodiment, further, the antenna assembly may further include a transmission line 19, and the antenna 14 is electrically connected to the second feed 18 through the transmission line 19 when in the receiving space. The transmission line 19 includes, but is not limited to, a coaxial cable or a microstrip line. One end of the transmission line 19 is connected with the antenna 14, and the antenna 14 pushes and pulls the transmission line 19 when moving, so that the transmission line 19 moves and deforms. The transmission line 19 may be entangled during the deformation process, or the motion trajectory deviates from the designed position to cause interference or interference to nearby components, which may also cause instability of the transmitted signal and increase the loss of the antenna signal. Therefore, a guiding device can be designed in the housing 11, and the guiding device is used for limiting the motion track of the transmission line 19 so as to guide the transmission line 19.

Preferably, as shown in fig. 6, the guiding device may include a position sensor 21 and a position limiting device 20, and both the position sensor 21 and the position limiting device 20 may be disposed in the accommodating space. The position sensor 21 is used for detecting the position of the antenna 14 to obtain the position information of the antenna 14. The position sensor 21 includes, but is not limited to, a displacement sensor, a pressure sensor, etc., and detects a corresponding parameter to determine the position information of the antenna 14. The limiting device 20 is used for applying force to the transmission line 19 according to the position information so as to limit the movement of the transmission line 19 within the set area. The spacing device 20 may include a processing module, a drive source (including but not limited to a motor), and an actuator (including but not limited to a hydraulic cylinder, linkage, etc.). The processing module controls the driving source to work according to the position information, and the driving source controls the execution component to support or pull the transmission line 19 to realize the straightening or rolling of the transmission line 19, so that the movement and deformation of the transmission line 19 are limited in a set area. The setting area is a predetermined movable range of the transmission line 19, and when the transmission line 19 can only move and deform in the setting area, the shape of the transmission line 19 is kept substantially stable, thereby preventing the transmission line 19 from being entangled, or preventing nearby components from being interfered or interfered due to deviation of a movement track, ensuring stability of a transmitted signal, and reducing loss of an antenna signal.

In this embodiment, when the support 13 moves, the operating frequency band of the antenna 14 moving along with the support 13 may shift, which may affect the normal operation of the antenna 14. Therefore, further, as shown in fig. 7, the electronic device 10 may further include a frequency offset correction module 22, and the frequency offset correction module 22 may be disposed on the main circuit board 17 and electrically connected to the antenna 14 for performing frequency offset correction on the frequency offset of the antenna 14. The frequency offset correction module 22 includes, but is not limited to, adjustable matching circuits, such as a switch for applying different parameters to the matching circuits, and the switch selects different matching circuits to perform frequency offset correction with different parameters. The frequency offset correction module 22 may perform frequency offset correction on the antenna 14 continuously in real time, that is, perform frequency offset correction in the whole motion process of the antenna 14, so as to ensure that the antenna 14 can normally operate at any position; alternatively, the frequency offset correction module 22 may perform frequency offset correction only at a desired time, for example, when the antenna 14 reaches the farthest position out of the receiving space, the frequency offset correction module 22 performs frequency offset correction. The latter approach is to reduce the power consumption of the frequency offset correction module 22 by only performing frequency offset correction at this time, considering that the user will typically communicate after the cradle 13 is moved into position.

As shown in fig. 1, in the present embodiment, a display 12 may be mounted on the housing 11, and the display 12 has a display area 121. Further, the ratio of the area of the display area 121 to the area of the display screen 12 may be greater than a preset value. As shown in fig. 8, further, the support 13 may be provided with a function module 23. The function module 23 is a module having a mechanical structure and a circuit structure, capable of receiving feedback of a user or an environment, collecting user or environment data, and implementing a specific function, and includes, but is not limited to, a camera module, a flash module, an infrared module, a distance measuring module, a light sensing module, a receiver module, a transmitter module, a face recognition module, an iris recognition module, and a fingerprint module. The functional module 23 is used for being moved out of the accommodating space along with the support 13 for a user to use, for example, the functional module 23 is a camera module, and the camera module shoots under the control of the user after extending out of the accommodating space.

In the existing product, the functional module 23 is fixed under the non-display area of the display screen 12, and the non-display area is used for shielding the functional module 23, so that the display area 121 of the display screen 12 is small in occupied ratio (namely, the screen is small in occupied ratio), and the display experience is limited. However, in the solution of this embodiment, the function module 23 is set as a removable accommodating space, and is used by the user after being removed, and does not need to play a role under the display 12. Thus, the display 12 does not need to provide a non-display area for the function module 23. On the contrary, the non-display area originally covering the functional module 23 on the display screen 12 can be designed into the display area 121, so that the proportion of the area of the display area 121 to the area of the display screen 12 is increased, the screen occupation ratio of the display screen 12 is increased, and the viewing experience is improved.

The electronic apparatus of the present invention is described in detail in the above embodiment, and a control method of the electronic apparatus of the present invention will be described below.

The embodiment of the invention provides a control method of electronic equipment, which is used for controlling the electronic equipment and comprises the following steps:

providing a first driving force to enable a support in the electronic equipment to drive the antenna to move out of the accommodating space;

and providing a second driving force to enable the support in the electronic equipment to drive the antenna to retract into the accommodating space.

The first driving force may include, among other things, a force applied by a user, and a force applied by a driving mechanism (including, but not limited to, purely mechanical and electrical driving mechanisms) internal to the electronic device. Therefore, providing the first driving force may refer to applying a force only by the user, applying an external force by the user and applying a force by the driving mechanism together, or applying a force only by the driving mechanism, so that the support and the antenna are moved out of the accommodating space. Accordingly, the second driving force may also include a force applied by the user, as well as a force applied by a driving mechanism internal to the electronic device. Thus, providing the second driving force may refer to the user applying only force, the user applying external force and the driving mechanism applying force together, or the driving mechanism applying only force, thereby moving the cradle and the antenna into the receiving space. In this embodiment, as described above, when the antenna moves out of the accommodating space, the antenna is electrically connected to the first feed source.

The control method of the embodiment can reduce the shielding effect of the shell on the antenna, increase the clearance area of the antenna, reduce the loss of the signal power of the antenna, and improve the efficiency of the antenna and the sensitivity of the antenna.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
