Technical Field

The invention relates to the technical field of communication equipment, in particular to electronic equipment.

background

The fifth generation mobile communication technology (5G) can provide higher communication speed, lower latency, and a larger number of simultaneous connections than the previous generation technologies. Among them, the millimeter wave communication technology with a frequency band above 20GHz is one of the key technologies in the 5G technology because of having a very wide communication bandwidth. Since the millimeter wave band is divided into 5G bands in many countries and regions in the world, various electronic products, particularly mobile communication terminals such as mobile phones, equipped with millimeter wave antenna modules will be increasing in the future.

Due to the large propagation loss and reflection loss of millimeter waves in space, the millimeter wave communication technology standard in the 5G technology stipulates that a millimeter wave antenna should have a gain above a certain degree to compensate for various losses in a spatial link. This requires the millimeter wave antenna to be in the form of an antenna array, and to realize phased array beam forming by controlling the phase difference between the sub-antennas in the array, so that the synthesized beam has higher gain.

Referring to fig. 1 to 2, an embodiment of the present invention provides an electronic device, including: a housing 10, a telescopic assembly 11, a first antenna sub-array 12 and a driving assembly (not shown in the figure);

the telescopic assembly 11 is movably connected with the shell 10 and can move linearly between a first position and a second position;

The first antenna subarray 12 is arranged on the telescopic component 11;

The driving assembly is connected with the telescopic assembly 11, and is used for driving the telescopic assembly 11 to move between a first position and a second position and driving the telescopic assembly 11 to rotate around an axis, wherein the axis is parallel to or coincident with the straight line;

In the first position (shown in fig. 1), the first antenna sub-array 12 is housed in the housing 10, and in the second position (shown in fig. 2), the first antenna sub-array 12 is located outside the housing 10.

to better illustrate the specific implementation of the embodiment of the present invention, a three-axis coordinate system as shown in fig. 1 is established, in the Z-axis direction, the upper end is the top end of the housing 10, and the lower end is the bottom end of the housing 10; the X-axis is the thickness direction of the housing 10. The driving assembly can drive the telescopic assembly 11 to be at a first position and a second position along the Z axis, and the extending direction of the axis is the axial direction of the Z axis.

Alternatively, the telescopic assembly 11 may be provided at the top end or the side of the housing 10. Specifically, in an alternative embodiment, the housing 10 may be provided with an opening, and the telescopic assembly 11 is disposed corresponding to the opening. Specifically, in an alternative embodiment, a shielding plate may be disposed at the opening, and when the telescopic assembly 11 is located at the first position, the telescopic assembly may be completely accommodated in the housing 10, and then the shielding plate shields the opening; when the telescopic assembly 11 needs to be controlled to move from the first position to the second position, the shielding plate is controlled to open the opening, and then the telescopic assembly 11 is controlled to move. In another embodiment, when the telescopic assembly 11 is located at the first position, the opening is covered by an end surface of the top of the telescopic assembly 11, specifically, the telescopic assembly 11 may have a gap with the end surface of the opening of the housing 10; of course, the smaller the gap, the better. Because the telescopic assembly 11 is accommodated in the housing 10, the telescopic assembly 11 can be effectively prevented from contacting the outside when the telescopic assembly 11 is not used. The service life of the telescopic assembly 11 can be effectively extended.

Alternatively, in this embodiment, the driving assembly may comprise a single body, which can drive the telescopic assembly to move between the first position and the second position, and can also drive the telescopic assembly 11 to rotate along the axis. In another embodiment, the drive assembly may also include two drive modules, one for driving the retraction assembly to move between the first position and the second position, and the other for driving the retraction assembly 11 to rotate along the axis. The structure and implementation of the driving assembly can refer to the related art, and are not further limited herein.

It should be noted that the manner of controlling the rotation of the telescopic assembly 11 may be set according to actual requirements, for example, in an embodiment, the rotation of the telescopic assembly 11 is independent from the telescopic movement (the movement between the first position and the second position). In this case, the telescopic assembly 11 may be rotated only at the second position, and may be rotated at any one of the first position, the second position, and the first position and the second position. In another embodiment, the rotation and the telescopic movement of the telescopic assembly 11 are controlled in combination, and the telescopic movement can be realized by controlling the telescopic assembly 11 to rotate at the first position and the second position.

The embodiment of the present invention allows the first antenna sub-array 12 to be located outside the housing 10 by disposing the first antenna sub-array 12 on the telescopic assembly 11. Therefore, when the first antenna sub-array 12 is used, the first antenna sub-array 12 can be prevented from being shielded, and therefore the communication quality of the electronic equipment is improved according to the embodiment of the invention. Meanwhile, the first antenna subarray 12 is arranged on the telescopic assembly 11, so that the narrow frame requirement of the overall screen design is not influenced, and the design difficulty caused by the fact that wires are arranged on two sides of the screen is solved.

optionally, the first antenna sub-array 12 includes at least two first antenna units 121, and a distance between two adjacent first antenna units 121 is equal.

in the embodiment of the present invention, the at least two first antenna units 121 may be linearly arranged and uniformly spaced on the telescopic assembly 11. The first antenna sub-array 12 may be a millimeter wave antenna array for receiving millimeter wave wireless signals.

The structure of the telescopic assembly 11 may be set according to actual needs, for example, in this embodiment, the outer shape of the telescopic assembly 11 is substantially a cylinder, the outermost structure of the side surface of the telescopic assembly 11 may be glass, and the first antenna unit 121 may be set inside the glass, so as to protect the first antenna unit 121. Of course, in other embodiments, the first antenna unit may be directly disposed on the side of the telescopic assembly 11, and the first antenna unit 121 is separately covered by a layer of protection structure, which is not further limited herein.

Further, in the embodiment of the present invention, a connection line of the at least two first antenna units 121 is parallel to the straight line.

In this embodiment, the first antenna sub-array 12 may be directed to a sector area parallel to the X-Z plane for beam scanning (in this embodiment, the X + direction of the X-Z plane) perpendicular to the X-Y plane to search for and align with a base station.

Further, during the process of searching and aligning the base station, the driving component may control the first antenna sub-array 12 to rotate, where the scanning range of the first antenna sub-array 12 is: the X + direction sector of the X-Z plane rotates the covered annular area along the Z-axis. The drive assembly may control the retraction assembly 11 to communicate at a fixed location after searching for an alignment base station. According to the embodiment of the invention, 360-degree omnidirectional scanning can be realized on an X-Y plane by controlling the telescopic assembly 11 to rotate, so that the scanning coverage of the antenna is enlarged.

further, referring to fig. 3, based on the above embodiment, in this embodiment, the telescopic assembly 11 is further provided with a second antenna sub-array 13, the second antenna sub-array 13 is located on a target side of the telescopic assembly 11, the target side is a side of the telescopic assembly 11 away from the housing 10 in a first direction when the telescopic assembly 11 is in the second position, and the first direction is a moving direction in which the telescopic assembly 11 moves from the first position to the second position, or a moving direction in which the telescopic assembly 11 moves from the second position to the first position.

As shown in fig. 3, the target side is the top of the retractable assembly 11, and the second antenna subarray 13 is disposed on the top of the retractable assembly 11, so that when the retractable assembly 11 is located at the first position and if the requirement on communication quality is low (for example, in a standby state), the second antenna subarray 13 can operate, and thus, the retractable assembly 11 does not need to be controlled to extend out of the housing 10, and the power consumption of the electronic device is reduced. In addition, in the embodiment of the present invention, since the second antenna sub-array 13 is added, beam scanning can be performed in another dimension, and the range of beam scanning is increased, thereby improving communication quality.

Optionally, in an embodiment, the second antenna sub-array 13 includes at least two second antenna units 131, and a distance between two adjacent second antenna units 131 is equal.

In the embodiment of the present invention, at least two second antenna units 131 may be linearly arranged and uniformly spaced on the telescopic assembly 11. The second antenna sub-array 13 may be a millimeter wave antenna array. Alternatively, the distance between two adjacent second antenna units 131 and the distance between two adjacent first antenna units 121 may be set to be equal. The second antenna sub-array 13 may be a millimeter wave antenna array for receiving millimeter wave wireless signals.

Further, a connection line of the at least two second antenna units 131 is perpendicular to the first direction. In the embodiment of the present invention, the second antenna sub-array 13 is perpendicular to the first antenna sub-array 12.

as shown in fig. 3, when the telescopic assembly 11 is in the first position or the second position and is not rotated, the second antenna sub-array 13 performs beam scanning on a sector area perpendicular to the X-Y plane and directed parallel to the Z-axis to search and align a base station; in the case of rotation of the telescopic assembly 11, the scan range is: the Y-Z plane Z + direction sector rotates the covered cone along the Z axis. At this time, the second antenna sub-array 13 scanning area is complementary to the sub-first antenna sub-array 12 scanning area.

In an embodiment, the first antenna unit 121 and the second antenna unit 131 are microstrip antennas, and may be, for example, square microstrip antennas or circular microstrip antennas. In other embodiments, other antenna forms with similar antenna characteristics are also possible.

Further, referring to fig. 4, the telescopic assembly 11 is further provided with a camera module 14.

In this embodiment, when the retractable assembly 11 is located at the first position, the camera module 14 is hidden in the housing 10, and when the retractable assembly 11 is located at the second position, the camera module 14 extends out of the housing 10.

Specifically, at the during operation, if only need use camera module 14, can control flexible subassembly 11 part and expose casing 10, guarantee that camera module 14 normally works, not sheltered from can. In this embodiment, as shown in fig. 4, the camera module 14 may be disposed opposite to the first antenna sub-array 12.

As shown in fig. 4, the telescopic assembly 11 includes a signal feeding line 15, a radio frequency module 16 and an antenna substrate 17, which are sequentially stacked, wherein the first antenna subarray 12 is disposed on a side of the antenna substrate 17 away from the radio frequency module 16, the first antenna subarray 12 is electrically connected to the radio frequency module 16 through the antenna substrate 17, and the radio frequency module 16 can be connected to a main board of an electronic device through the signal feeding line 15, so as to implement a transceiving function of the first antenna subarray 12. The signal feeding circuit 15 may be a flexible circuit board.
