Technical Field

The invention relates to the technical field of communication equipment, in particular to a mobile terminal.

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.

Disclosure of Invention

the embodiment of the invention provides a mobile terminal, which aims to solve the problem of poor communication quality caused by narrow beam scanning range.

In a first aspect, an embodiment of the present invention provides a mobile terminal, including: a housing, a telescoping assembly, a first antenna sub-array and a second antenna sub-array, wherein,

The second antenna subarray is arranged on the second surface of the telescopic assembly;

Wherein the first surface is adjacent to the second surface and the first and second sub-arrays of antennas are located outside the housing when the expansion assembly is in the second position.

According to the embodiment of the invention, the first antenna sub-array and the second antenna sub-array are arranged on two different surfaces of the telescopic component, so that beam scanning can be carried out on the first antenna sub-array and the second antenna sub-array in different directions, and therefore, the coverage range of beam scanning is improved, and the communication quality is improved.

Referring to fig. 1, an embodiment of the present invention provides a mobile terminal including a housing 11, a telescopic assembly 12, a first antenna sub-array 13 and a second antenna sub-array 14, wherein,

The telescopic assembly 12 is movably connected with the shell 11 and can move between a first position and a second position;

The first antenna subarray 13 is arranged on the first surface 121 of the telescopic assembly 12;

The second antenna sub-array 14 is disposed on the second surface 122 of the telescopic assembly 12;

wherein the first surface 121 is adjacent to the second surface 122, and when the telescopic assembly 12 is located at the second position, the first antenna subarray 13 and the second antenna subarray 14 are located outside the housing 11.

to better illustrate the specific implementation manner of the embodiment of the present invention, a three-axis coordinate system as shown in fig. 1 is established, in the Y-axis direction, the upper end is the top end of the housing 11, and the lower end is the bottom end of the housing 11; the Z-axis is the thickness direction of the housing.

In the embodiment of the present invention, the first surface 121 may be disposed adjacent to the second surface 122, or may be disposed opposite to the second surface, as long as the two surfaces are not in the same plane. Optionally, the shape of the telescopic assembly may be set according to actual needs, for example, the telescopic assembly may be a cube, a cuboid, a cylinder, or another polygonal prism structure. As shown in fig. 1, in the following embodiments, the telescopic assembly 12 is described in detail as an example of a rectangular parallelepiped.

The screen cover is usually a glass cover, but in practical applications, other transparent non-metal materials may also be used, for example, a screen cover made of transparent plastic and other materials.

Optionally, the housing 11 may be provided with an opening adapted to the telescopic assembly 12. The position of the specific opening can be set according to actual requirements, for example, in the embodiment of the present invention, the opening is located at the top end of the housing 11.

In an alternative embodiment, the retraction assembly 12 is manually movable between a first position and a second position; in an alternative embodiment, a drive member may be provided within housing 11, whereby retraction assembly 12 is driven from the first position to the second position, and whereby retraction assembly 12 is controlled manually or by the drive member to return from the second position to the first position. The driving component may be a motor, an electromagnet, or an elastic component, and the specific structure may refer to the related art, which is not further limited herein. Specifically, when the first antenna subarray 13 and the second antenna subarray 14 work, the driving component 12 can be controlled to move to the second position, and when the first antenna subarray 13 and the second antenna subarray 14 do not need to be used, the driving component 12 can be controlled to move to the first position, so that the first antenna subarray 13 and the second antenna subarray 14 are hidden in the shell 11, the first antenna subarray 13 and the second antenna subarray 14 are prevented from being in contact with the outside, and the safety of using the first antenna subarray 13 and the second antenna subarray 14 is improved.

In the embodiment of the present invention, the first antenna subarray 13 and the second antenna subarray 14 are disposed on two different surfaces of the telescopic assembly 12, so that beam scanning can be performed in different directions through the first antenna subarray 13 and the second antenna subarray 14, and therefore, the coverage of beam scanning is improved in the embodiment of the present invention, and communication quality is improved. Furthermore, because the antenna sub-arrays are disposed on the telescoping assembly 12, there is no interference with Indium Tin Oxide (ITO) traces on the sides and bottom of the screen.

Optionally, the housing 11 includes a screen cover 111, and the first surface 121 is oriented in the same direction as the screen cover 111. As shown in fig. 1, the first surface 121 and the screen cover 111 are both oriented in the positive direction of the Z axis (i.e., Z +).

the screen cover 111 is usually a glass cover, but in practical applications, other transparent non-metal materials may be used, for example, a screen cover made of transparent plastic and the like. Since the upper side of the screen is generally not shielded when the user uses the mobile terminal, in the embodiment, the first antenna subarray 13 is disposed on the side facing the screen cover 111, so that the possibility of being shielded can be avoided, and the passing quality can be improved.

Further, in addition to the antenna sub-arrays provided on the first surface 121 and the second surface, the antenna sub-arrays may be provided on other surfaces.

optionally, in an optional embodiment, as shown in fig. 2 (the viewing angle of fig. 2 is different from the viewing angle of fig. 1, fig. 1 is a schematic perspective structure of a front surface, and fig. 2 is a schematic perspective structure of a back surface), the mobile terminal further includes a third antenna sub-array 15, the third antenna sub-array 15 is disposed on a third surface 123 of the telescopic assembly 12, and the third surface 123 is disposed opposite to the first surface 121. It should be understood that the first antenna sub-array 13 and the second antenna sub-array 14 are included in fig. 2, and that the first antenna sub-array 13 and the second antenna sub-array 14 are not shown in fig. 2 due to the viewing angle.

Optionally, in another optional embodiment, as shown in fig. 2, the mobile terminal further includes a fourth antenna sub-array 16, where the fourth antenna sub-array 16 is disposed on a fourth surface 124 of the telescopic assembly 12, and the fourth surface 124 is disposed opposite to the second surface 122.

optionally, in yet another optional embodiment, as shown in fig. 3 (the viewing angle of fig. 3 is the same as the viewing angle of fig. 2), the mobile terminal further includes a fifth antenna sub-array 17, the fifth antenna sub-array 17 is disposed on a fifth surface 125 of the telescopic assembly 12, and the fifth surface 125 is disposed adjacent to the first surface 121 and the second surface 122, respectively. In this embodiment, optionally, when the retraction assembly 12 is partially outside the housing 11, the fifth surface 125 is disposed away from the housing 11.

It should be noted that in the embodiments of the present invention, an antenna sub-array may be disposed on at least one of the third surface 123, the fourth surface 124, and the fifth surface 125, and in the following embodiments, the antenna sub-array is disposed on all of the third surface 123, the fourth surface 124, and the fifth surface 125.

Specifically, as shown in the drawings, when the telescopic member 12 is a rectangular parallelepiped, the front surface of the telescopic member 12 is a first surface 121, the right side surface is a second surface 122, the back surface is a third surface 123, the fourth surface of the left side surface, and the top surface is a fifth surface 125. It should be understood that the first antenna sub-array 13 and the second antenna sub-array 14 are included in fig. 2, and that the first antenna sub-array 13 and the second antenna sub-array 14 are not shown in fig. 2 due to the viewing angle.

Furthermore, each antenna subarray comprises at least two antenna units, and the at least two antenna units are uniformly spaced and linearly distributed.

As shown in fig. 1, in the embodiment of the present invention, at least two antenna elements included in the first antenna sub-array 13 are linearly arranged in the Y-axis (vertical) direction; at least two antenna units included in the second antenna sub-array 14 are linearly arranged in the Y-axis direction; at least two antenna units included in the third antenna sub-array 15 are linearly arranged in the Y-axis direction; at least two antenna elements included in the fourth antenna sub-array 16 are linearly arranged in the Y-axis direction; the fifth antenna sub-array 17 includes at least two antenna elements linearly arranged in the X-axis direction.

Specifically, in the embodiment of the present invention, the first antenna subarray 13 may perform beam scanning in the + Z direction of the Y-Z plane; the second antenna sub-array 14 may be scanned with a beam in the + X direction of the X-Y plane. In this way, the two antenna sub-arrays of the first antenna sub-array 13 and the second antenna sub-array 14 can scan and cover in two mutually orthogonal dimensions respectively, and the spatial coverage rate of the antenna is improved.

In the embodiment of the present invention, the third antenna sub-array 15 is configured to perform beam scanning in the-Z direction of the Y-Z plane, and the fourth antenna sub-array 16 is configured to perform beam scanning in the-X direction of the X-Y plane. The third antenna subarray 15 and the fourth antenna subarray 16 are arranged, so that the beam scanning range is further improved, and the traffic quality is improved.

The fifth antenna subarray 17 may perform beam scanning in the + Y direction of the X-Y plane, and since the fifth antenna subarray is disposed on the fifth surface 125, passing quality is improved, and meanwhile, when the requirement on communication quality is low, the telescopic assembly 12 does not need to be controlled to move to the second position.

further, based on the above embodiment, in the embodiment of the present invention, the telescopic assembly 12 is further provided with a camera module 18, when the telescopic assembly 12 is located at the first position, the camera module 18 is hidden in the housing 11, and when the telescopic assembly 12 is located at the second position, the camera module 18 is located outside the housing 11.

In an embodiment of the present invention, the camera module 18 may include a front camera and/or a rear camera. As shown in fig. 1, the lens of the camera module 18 is disposed on the first surface 121, and the camera module 18 may be a front camera in this embodiment, for capturing an image of an area above the screen.

Specifically, when the camera is used and beam scanning is not performed, the telescopic component part can be controlled to stretch out, and the requirements of photographing or video recording are met.

It should be noted that the structure and the number of the antenna elements of each antenna array may be set according to actual needs, for example, in the embodiment of the present invention, the number of the antenna elements included in the first antenna sub-array 13, the second antenna sub-array 14, the third antenna sub-array 15, the fourth antenna sub-array 16, and the fifth antenna sub-array 17 is 4, and the polarization form of the antenna elements is an orthogonal dual-polarization antenna, but a single-polarization antenna or a circular polarization antenna is not excluded. That is, in an alternative embodiment, each antenna element is an orthogonal dual-polarized feed.

The antenna unit is a microstrip antenna, and may be, for example, a square microstrip antenna or a circular microstrip antenna. In other embodiments, other antenna forms with similar antenna characteristics are also possible.
