The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 8, an embodiment of the present invention provides an electronic device, including: the antenna module 20 and the driving assembly 30 are located in the housing 10, the antenna module 20 is connected to the driving assembly 30, and a moving channel (not shown) for moving the antenna module 20 is located in the housing 10, and the antenna module 20 can move from a first position to a second position in the moving channel under the driving of the driving assembly 30; wherein the radiation efficiency of the antenna module 20 in the first position is lower than the radiation efficiency in the second position. The antenna module may include a radiator, a feeder, a feed, etc. which constitute basic components of the antenna, and may further include components for improving radiation performance. The antenna module may also be an antenna array. The driving assembly may include a power source, a transmission mechanism, and the like, which implement basic components of the antenna module to move. The specific method can be determined according to actual use, and the embodiment of the invention is not limited.
In the present embodiment, a movement channel for the antenna module 20 to move is provided in the housing 10, so as to satisfy the movement of the antenna module 20 on the inner side of the housing 10, and the antenna module 20 can move in the movement channel under the driving of the driving assembly 30, so that the antenna module 20 moves to the second position, thereby improving the radiation efficiency of the antenna module 20. The motion channel may include a space for the antenna module to move, and a guide member, a stopper member, and other basic components provided in the space. The specific method can be determined according to actual use, and the embodiment of the invention is not limited.
The first position is a current position of the antenna module 20, and when it is detected that the radiation efficiency of the antenna module 20 at the first position is low, the antenna module 20 can be driven to move by controlling the driving component 30, so that the antenna module 20 moves to the second position with high radiation efficiency, and the purpose of improving the radiation efficiency of the antenna module 20 is achieved.
For example, when the functional device near the antenna module 20 starts to operate, in order to prevent the radiation signal of the antenna module 20 from interfering with the functional device 40, or prevent the radiation signal of the antenna module 20 from interfering with the current field generated when the functional device 40 operates, the antenna module 20 may be driven away from the functional device 40 by controlling the driving component 30, so as to avoid the problem of mutual interference between the functional device and the antenna module 20.
As shown in fig. 4, when the functional device 40 is a retractable device, and when the functional device 40 is moved out of the housing 10, the space originally used for accommodating the functional device 40 may also be used as a movement space of the antenna module 20, so as to improve the antenna directivity and the heat dissipation performance of the antenna module 20 in the scene.
Optionally, the electronic device may further include a detection component (not shown) and a control component (not shown), where the control component is electrically connected to the detection component and the driving component 30, respectively, and the detection component is configured to detect a first radiation efficiency of the antenna module 20 at the first position; the control component is used for controlling the driving component 30 to drive the antenna module 20 to move to the second position when the first radiation efficiency is lower than the preset radiation efficiency. The detection component may be a detection circuit, and the detection circuit of the antenna radiation efficiency may be implemented by using a mature technology, which is not limited in the embodiment of the present invention. The control component may be a control circuit, and the control circuit may include a processor, a switch, an input/output unit, a power circuit, and the like, which is not limited in the embodiment of the present invention.
In this embodiment, since the radiation efficiency of the antenna module 20 at the second position is higher than the first radiation efficiency, that is, higher than the radiation efficiency of the antenna module 20 at the first position, the antenna module 20 can be moved from the first position to the second position, so as to achieve the purpose of improving the radiation efficiency of the antenna module 20.
The control component may send a control signal to the driving component, and after receiving the control signal, the driving component 30 may execute a corresponding operation according to the control signal. For example, when the driving component 30 receives a control signal for driving the antenna module 20 to move to the second position, the driving component 30 is activated, and the antenna module 20 is driven to move to the second position, so as to achieve the purpose of improving the radiation efficiency of the antenna module 20.
As shown in fig. 5 and 6, the electronic device includes a first screen and a second screen which are foldable, one of the first screen and the second screen is provided with an antenna module 20, the other screen is provided with another module 70, the other module 70 may be another antenna module, a camera or other devices capable of radiating electromagnetic waves, and when the other module 70 is in an operating state, the radiation efficiency of the antenna module 20 can be reduced.
In this embodiment, in order to avoid the influence of the other modules 70 on the radiation efficiency of the antenna module 20, when the first screen and the second screen are in the folded state, the control component may control the driving component 30 to drive the antenna module 20 to move from the first position to the second position, where the first position is located between the other modules 70 and the second position, that is, the driving component 30 drives the antenna module 20 to move in a direction away from the other modules 70 and move to the second position, so as to reduce the interference influence of the other modules 70 on the antenna module 20.
Alternatively, the antenna module 20 in this embodiment may be a millimeter wave antenna module, and since the wavelength of the millimeter wave antenna is very short, the length of the antenna is generally 1/4 of the wavelength. Calculation formula of wavelength: wavelength is the wave speed (30 kilometres/second)/frequency. There is a range of frequencies of 5G millimeter wave, for example 28GHz, the length of the antenna is 1/4 wavelength (30 km/s)/28 GHz ≈ 2.68mm, and it can be seen that the length of the millimeter wave antenna is generally about several millimeters.
Moreover, in the design of the electronic device, the millimeter wave antenna is implemented by an antenna array, and the radio frequency unit and the antenna unit are integrated into one module, that is, the antenna module 20 in this embodiment has a small length and a small volume, so that the driving assembly 30 can drive the antenna module 20 to move in the moving channel in the housing, so as to optimize and improve the radiation efficiency of the antenna module 20.
The movement channel disposed in the housing 10 may be disposed along a length direction of the electronic device, may also be disposed along a width direction of the electronic device, and may also be disposed in a diagonal direction of the electronic device; the setting of the motion channel is related to the layout of functional devices of the electronic equipment; alternatively, the movement channel may be disposed in a region spaced apart from the functional device or a region where the functional device is not disposed, so as to reduce the mutual interference effect between the functional device and the antenna module 20.
Optionally, the driving assembly 30 includes a driving motor 31 and a transmission mechanism 32, and as shown in fig. 7 in particular, the driving motor 31 drives the transmission mechanism 32 to move, so as to drive the antenna module 20 to move. Wherein, the driving motor 31 may be a stepping motor so that the moving distance of the antenna module 20 may be precisely controlled; the transmission mechanism 32 may be a lead screw mechanism so that a stable transmission capability can be provided.
The transmission mechanism 32 may also be a telescopic rod structure, and the driving motor 31 drives the telescopic rod structure to extend and retract so as to drive the antenna module 20 to move.
Optionally, in order to ensure that the antenna module 20 can also have stable electrical connection with the main board 50 of the electronic device during the moving process, the antenna module 20 and the main board 50 may be electrically connected through a flexible connecting member 60, as shown in fig. 8 in particular; the flexible connector 60 may be a flexible circuit board. The flexible circuit board has good bending property, and can still ensure good electric connection performance after being folded tens of thousands of times.
Moreover, in the case that the flexible connector 60 is a flexible circuit board, the service life of the flexible circuit board can be prolonged by ensuring a certain bending radius.
The electronic Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
As shown in fig. 9, another embodiment of the present invention provides an antenna control method, which can be applied to the electronic device of the above embodiment, where the electronic device includes an antenna module and a driving component, and the driving component is in driving connection with the antenna module, and the antenna control method includes:
step 901, detecting a first radiation efficiency of the antenna module at a first position under the condition that a preset condition is met.
In this step, a first radiation efficiency of the antenna module at the first position may be detected by a detection component disposed on the electronic device.
The preset conditions include, but are not limited to, the following conditions: a functional device in a working state is arranged in a preset range away from the first position; the temperature of the electronic equipment at the first position is higher than a preset temperature; the position where the electronic equipment is held is opposite to the first position.
It should be noted that, in all of the above cases, the radiation efficiency of the antenna module is affected, and therefore, for a scene that affects the radiation efficiency of the antenna module, the scene that meets the preset condition may be summarized.
For example, when a user uses a certain function, a functional device corresponding to the function may affect a radiation signal of the antenna module in the use process; for example, long-time downloading of a large data packet results in high temperature rise in the area where the antenna module is located, which affects the reduction of radiation efficiency of the antenna module and the temperature rise on the surface of the whole device; such as poor signal of the current environment; for another example, when the user holds the electronic device, radiation of the antenna module is blocked.
And 902, controlling the driving component to drive the antenna module to move from the first position to the second position under the condition that the first radiation efficiency is lower than a preset radiation efficiency, so that the radiation efficiency of the antenna module at the second position is greater than the first radiation efficiency.
In this step, under the condition that the first radiation efficiency is lower than the preset radiation efficiency, the driving assembly is controlled to drive the antenna module to move from the first position to the second position, so that the radiation efficiency of the antenna module at the second position is greater than the first radiation efficiency, and the purpose of improving the radiation efficiency of the antenna module is achieved.
The radiation efficiency of the antenna module at the first position is interfered by other functional devices or driving circuits, so that the radiation efficiency of the antenna module is reduced; or, the antenna module is shielded by other objects at the first position, which results in the reduction of the radiation efficiency of the antenna module; the radiation efficiency of the antenna module can be improved by moving the antenna module from the first position to the second position.
As shown in fig. 1 to fig. 3, for example, the functional device 40 is a camera, and when the camera is interfered due to the high power of the antenna module 20 or the radiation efficiency of the antenna module is interfered by the camera during a video call of a user, the antenna module 20 may be driven to move (i.e., move to the second position) in a direction away from the camera by controlling the driving component 30, so as to increase the distance between the antenna module 20 and the functional device 40 (camera), and reduce or even eliminate mutual interference, so as to improve the radiation efficiency of the antenna module 20.
For another example, when a user plays a large game, the user needs to grip the electronic device with both hands, and when the antenna module is located in the holding area, the both hands of the user can shield the radiation signal of the antenna module, thereby reducing the radiation efficiency of the antenna module. In this case, the radiation efficiency of the antenna module can be improved by determining the area where the electronic device is held and controlling the driving component to drive the antenna module to move towards the area where the electronic device is not held.
For another example, when the signal of the environment where the electronic device is located is poor, in order to improve the directivity of the antenna module, the antenna module may be moved toward a direction away from the nearby functional device, so as to pull the distance between the antenna module and the functional device apart, reduce or even eliminate the mutual interference, and achieve the purpose of improving the directivity of the antenna.
Optionally, the detecting, under the condition that a preset condition is met, a first radiation efficiency of the antenna module at a first position includes: detecting first radiation efficiency of the antenna module at a first position under the condition that a functional device in a working state is arranged in a preset range away from the first position; the controlling the driving component to drive the antenna module to move from the first position to the second position includes: controlling the driving component to drive the antenna module to move from the first position to a second position, wherein the first position is located between the functional device and the second position.
In this embodiment, the antenna module can be driven to be away from the functional device by controlling the driving component, so as to avoid the problem of mutual interference between the functional device and the antenna module.
When the functional device is a retractable device and the functional device is moved out of the housing, the space originally used for accommodating the functional device can also be used as a movement space of the antenna module, so that the antenna directivity and the heat dissipation performance of the antenna module in the scene are improved.
Optionally, in the process of downloading a large data packet for a long time, the antenna module can continuously work, so that the temperature rise of the area where the antenna module is located is easily overhigh, the radiation efficiency of the antenna module is reduced, and the surface temperature of the whole electronic equipment is overhigh; under the condition, the antenna module can be driven to move left and right back and forth by controlling the driving component, so that the heat dissipation of the antenna module is improved, and the phenomenon of overhigh temperature rise of a local area is avoided.
Optionally, the electronic device includes a first foldable screen and a second foldable screen, one of the first screen and the second screen is provided with the antenna module, and the other screen is provided with other modules, where the other modules are functional modules capable of reducing radiation efficiency of the antenna module; the controlling the driving component to drive the antenna module to move from the first position to the second position includes: under the condition that the first screen and the second screen are in a folded state, the driving assembly is controlled to drive the antenna module to move from the first position to the second position, and the first position is located between the other modules and the second position.
In this embodiment, in order to avoid the influence of other modules on the radiation efficiency of the antenna module, when the first screen and the second screen are in the folded state, the driving assembly may be controlled by the control assembly to drive the antenna module to move from the first position to the second position, and the first position is located between the other modules and the second position, that is, the driving assembly drives the antenna module to move towards the direction away from the other modules and to move to the second position, so as to reduce the interference influence of the other modules on the antenna module.
The other modules can be other antenna modules, cameras or other devices, and when the other modules are in a working state, the radiation efficiency of the antenna modules can be reduced.
According to the antenna control method provided by the embodiment of the invention, under the condition that a preset condition is met, the first radiation efficiency of the antenna module at a first position is detected; under the condition that the first radiation efficiency is lower than a preset radiation efficiency, the driving component is controlled to drive the antenna module to move from the first position to the second position, so that the radiation efficiency of the antenna module in the second position is larger than the first radiation efficiency. Therefore, the antenna module can be driven to move from the first position to the second position by controlling the driving component, so that the radiation efficiency of the antenna module at the second position is greater than the first radiation efficiency, and the purpose of improving the radiation efficiency of the antenna module is achieved.
