In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Referring to fig. 1, fig. 1 is a schematic perspective view of a Customer premises equipment 1000 (CPE) according to an embodiment of the present application. The client terminal device 1000 according to the embodiment of the present application is a wireless broadband access device, and the client terminal device 1000 may convert a signal transmitted by the Base Station 1100(Base Station) into a wifi (wireless fidelity) signal that is commonly used by mobile terminals such as a tablet computer, a smart phone, and a notebook, and may simultaneously support a plurality of mobile terminals to access the internet. The client terminal apparatus 1000 may also transmit data to the base station 1100 to transmit the data to the server center through the base station 1100.

The client terminal apparatus 1000 may be installed indoors or outdoors. Specifically, when the client terminal apparatus 1000 is installed indoors, the client terminal apparatus 1000 may be installed on a wall, may be placed on a desktop, or the like. When the client terminal apparatus 1000 is installed outdoors, the client terminal apparatus 1000 may be fixed to a wall, for example, the client terminal apparatus 1000 may be fixed to the wall by a mounting bracket. The customer terminal device 1000 located outdoors may be connected to a commercial power supply indoors through a wire so that commercial power may continuously supply power to the customer terminal device 1000.

The client terminal device 1000 may have a regular shape such as a cylindrical shape or a square cylindrical shape, and of course, the client terminal device 1000 may have other special shapes. In the client terminal apparatus 1000 shown in fig. 1, the cross section of the client terminal apparatus 1000 is substantially elliptical.

Referring to fig. 2 to 4, in the present embodiment, the client terminal device 1000 includes a housing 500, a frame 400, a heat dissipation fan 300, an antenna unit 200, and an antenna assembly 100. The frame 400 is disposed in the housing 500, and the frame 400 is used for carrying internal components of the client terminal device 1000, for example, the frame 400 is used for carrying the antenna component 100 and the heat dissipation fan 300. The heat dissipation fan 300 is disposed inside the housing 500, and the heat dissipation fan 300 is used to generate an air flow to dissipate heat inside the housing 500 to the outside of the housing 500.

The antenna unit 200 is disposed within the housing 500, and the antenna unit 200 serves to transceive signals. The antenna component 100 is at least partially disposed within the housing 500. The antenna section 100 is used for transceiving millimeter wave signals. The operating frequency band of the antenna component 100 is different from the operating frequency band of the antenna unit 200. Alternatively, the frequency of the signal transmitted and received by antenna element 200 is different from the frequency of the signal transmitted and received by antenna element 100.

Specifically, the housing 500 is an external part of the client terminal apparatus 1000. The housing 500 may constitute an outer shape of the client terminal apparatus 1000, or in other words, a specific shape of the client terminal apparatus 1000 is substantially determined by the housing 500. For example, when the housing 500 has a cylindrical shape, the overall shape of the client terminal apparatus 1000 has a cylindrical shape.

It is understood that the housing 500 may have a hollow structure, and the housing 500 may receive internal components of the terminal device 1000 to protect the internal components of the client terminal device 1000. For example, the housing 500 can reduce the impact on the internal components of the client terminal device 1000, and prevent the internal components from being displaced and affecting the normal use of the client terminal device 1000. For another example, the housing 500 may reduce contact between foreign objects such as dust and moisture and the internal components, and prevent the internal components from being damaged by short circuit.

The housing 500 may be made of metal or plastic. In order to improve the ability of the client terminal apparatus 1000 to transmit and receive signals, the housing 500 may be made of a non-shielding material such as plastic. As such, signals may penetrate the housing 500 to be received by the antenna unit 200 or the antenna component 100 within the housing 500. In addition, the antenna unit 200 or the antenna part 100 inside the housing 500 may transmit signals through the housing 500.

Of course, the housing 500 may be made of a variety of materials depending on the specific function of the housing 500. For example, the housing 500 may be made of a material having a relatively high strength, such as metal, as a load-bearing portion.

Referring to fig. 2, in some embodiments, the housing 500 may have a heat dissipation channel 510, and the heat dissipation channel 510 is used for dissipating heat in the housing 500 to the outside of the housing 500. Thus, the heat in the housing 500 can be dissipated to the outside of the housing 500 through the heat dissipation channel 510, thereby reducing the temperature in the housing 500 and ensuring the normal operation of the client terminal device 1000.

Specifically, the heat dissipation channel 510 may be a circular hole, a square hole, or a hole with a special shape such as a special shape. In addition, the number of the heat dissipation channels 510 may be multiple, the plurality of heat dissipation channels 510 may be arranged at intervals along the circumferential direction of the housing 500, and the plurality of heat dissipation channels 510 may increase the heat dissipation area of the heat in the housing 500, thereby improving the cooling rate of the client terminal device 1000.

Further, in some embodiments, the heat dissipation channel 510 may be located at the top of the housing 500. It can be appreciated that the air having a relatively high temperature generally flows upward, and thus, the heat dissipation channel 510 is disposed at the top of the housing 500 to facilitate the heat inside the housing 500 to be dissipated through the heat dissipation channel 510.

Note that, in the present embodiment, the "top" refers to a portion located above the client terminal apparatus 1000 in a case where the client terminal apparatus 1000 is normally used. For example, in the height direction, the height of the top of the client terminal apparatus 1000 is 1/3 of the total height of the client terminal apparatus 1000. Therefore, the top of the housing 500 is the upper part of the housing 500 in the case where the client terminal apparatus 1000 is normally used.

The heat dissipation channel 510 may be formed on the top end surface of the housing 500, may be formed on the side surface of the housing 500, or may be formed with the heat dissipation channel 510 on both the top end surface and the side surface of the housing 500.

Of course, the heat dissipation path 510 may be omitted when the amount of heat dissipated by the client terminal apparatus 1000 is sufficiently small. The heat dissipation amount of the client terminal apparatus 1000 can be transmitted to the outside of the housing 500 through the housing 500.

Referring to fig. 5-6, in some embodiments of the present application, a housing 500 includes a base 520, a surrounding wall 530, and a top cover 540. The surrounding wall 530 connects the base 520 and the surrounding wall 530. Specifically, the base 520 and the surrounding wall 530 may be separate structures, or the surrounding wall 530 may be detachably mounted on the base 520. Of course, the base 520 and the wall 530 may be a unitary structure. The surrounding wall 530 and the top cover 540 may be separate structures or may be an integrated structure.

The base 520 may provide support for the client terminal apparatus 1000 when placed on a support surface such as a desktop. The base 520 may have a block shape or a plate shape. In the embodiment of the present application, the base 520 is provided with an air inlet channel 521, and the air inlet channel 521 is used for allowing external air of the client terminal device 1000 to enter the casing 500, so that the air absorbs heat generated by the client terminal device 1000 and then is dissipated to the outside of the casing 500 from the heat dissipation channel 510.

The surrounding walls 530 may form a receiving space for receiving internal components of the client terminal apparatus 1000. The peripheral wall 530 may be a continuous structure, or the peripheral wall 530 may not be formed with a joint seam. In the embodiment of the present application, the connector 600 of the client terminal apparatus 1000 is exposed from the surrounding wall 530, as shown in fig. 4 to 5. The client terminal device 1000 can communicate with other devices or connect power through the connector 600. The connector 600 is, for example, a usb (universal Serial bus) connector 600, a power socket, or the like. The embodiments of the present application do not limit the specific type of the connector 600.

The top cover 540 may cover the top of the enclosing walls 530. The top cover 540 may shield internal components of the client terminal apparatus 1000 from the top of the enclosure wall 530. The top cover 540 may have a sheet or block configuration. In addition, the outer end surface of the top cap 540 may have a circular, oval, or the like shape, and the structure and shape of the top cap 540 are not limited thereto.

In the present embodiment, the heat dissipation channel 510 is disposed at the junction of the top cover 540 and the surrounding wall 530. Alternatively, the heat dissipation channel 510 is located between the top end of the surrounding wall 530 and the top cover 540. When the heat dissipating channel 510 is annular, the heat dissipating channel 510 may be formed by a gap formed by the top cover 540 and the surrounding wall 530 at a distance.

In some embodiments, the housing 400 serves as a load bearing element of the client terminal device 1000. The internal components of the client terminal apparatus 1000 may be mounted on the housing 400. For example, at least one of the heat dissipation fan 300, the antenna unit 200, and the antenna part 100 may be mounted on the frame 400. For another example, the main circuit board 700 of the client terminal device 1000 is mounted on the housing 400. The internal components of the client terminal apparatus 1000 may be mounted on the housing 400 by means of screws, snaps, and the like, and the specific mounting manner of the internal components is not limited herein.

Since the configuration of the housing 400 is adapted to the mounting position of the internal components of the client terminal apparatus 1000, the shape of the housing 400 is generally irregular. In order to facilitate the manufacturing and molding of the frame 400, the frame 400 may be molded by an injection molding process.

Of course, in other embodiments, the frame 400 may be omitted in case the housing 500 may support the client mobile terminal 1000.

Referring to fig. 3-4, in the present embodiment, the heat dissipation fan 300 is spaced apart from the antenna element 100, and the heat dissipation fan 300 is used for generating an air flow to dissipate heat in the housing 500 to the outside of the housing 500 through the heat dissipation channel 510. Or, when the heat dissipation fan 300 operates, the airflow with heat flows out of the housing 500 from the inside of the housing 500 through the heat dissipation channel 510. Thus, the heat dissipation fan 300 can accelerate the flow of air, thereby reducing the internal temperature rise of the client terminal device 1000 and ensuring the normal use of the client terminal device.

For example, the heat dissipation fan 300 may suck air with a relatively low temperature from the air intake channel 521 during operation, so that the air with a relatively low temperature absorbs heat of the housing 500 and is discharged from the heat dissipation channel 510.

In the present embodiment, the heat dissipation fan 300 is located above the antenna member 100. The term "upward" as used herein means that the direction in which the client terminal apparatus 1000 is away from the ground is "upward" in a case where the client terminal apparatus 1000 is normally used. Therefore, in the present embodiment, the position of the heat dissipation fan 300 is higher than the position of the antenna member 100.

The heat dissipation fan 300 may be connected to the main circuit board 700 of the client terminal apparatus 1000 by a wire, and the main circuit board 700 may control the operation of the heat dissipation fan 300. The heat dissipation fan 300 may be a centrifugal fan or an axial fan, and the specific type of the heat dissipation fan 300 is not limited herein, as long as the heat dissipation fan 300 can dissipate the heat in the casing 500 to the outside of the casing 500 through the heat dissipation channel 510.

Of course, in other embodiments, the heat dissipation fan 300 may be omitted when the amount of heat dissipated by the client terminal apparatus 1000 is sufficiently small. The heat dissipation amount of the client terminal apparatus 1000 may be transferred to the outside of the case 500 through the case 500 or dissipated to the outside of the case 500 through the heat dissipation channel 510.

In the embodiment of the present application, the operating frequency band of the antenna unit 200 may be below 6GHz (Sub-6 GHz). For example, the operating frequency bands of the antenna unit 200 are 3.3-3.6GHz and 4.8-5.0 GHz. That is, the antenna unit 200 can transceive 5G signals. It is understood that the antenna unit 200 has an antenna, and the antenna unit 200 transceives signals through the antenna.

As shown in fig. 3, in some embodiments, the number of the antenna units 200 is multiple, and the multiple antenna units 200 are arranged along the circumferential direction of the housing 500. Since the signal has directivity, a plurality of antenna elements 200 are arranged in the circumferential direction of the housing 500, which makes it possible for the client terminal apparatus 1000 to transceive the signal in various directions, improving the ability of the client terminal apparatus 1000 to transceive the signal.

Specifically, the antenna unit 200 is sheet-shaped. Among the plurality of antenna units 200, a part of the antenna units 200 may be attached to the frame 400, and a part of the antenna units 200 may be attached to the inner surface of the housing 500. The antenna unit 200 may be connected to the main circuit board 700 by a conductor so that the main circuit board 700 may control the antenna unit 200 to transmit and receive signals.

Of course, in other embodiments, the antenna unit 200 may be omitted.

Referring to fig. 7, in some embodiments of the present application, an antenna assembly 100 includes a support 10, a millimeter wave antenna module 20, and a multi-axis rotating mechanism 90. The multi-axis rotation mechanism 90 includes a fixed member 91 and a rotation member 92 rotatably provided on the fixed member 91 about multiple axes. The bracket 10 is fixedly connected with the rotating member 92. The rotator 92 millimeter wave antenna module 20 is fixed to the support 10.

In the antenna component 100 and the client terminal device 1000 according to the embodiment of the present application, the multi-axis rotating mechanism 90 may rotate the millimeter wave antenna module 20 around multiple axes along with the support 10, so that the rotation range of the millimeter wave antenna module 20 is wider, and thus the millimeter wave antenna module 20 may rotate to a predetermined position where a signal is stronger to transmit and receive the signal, and further the client terminal device 1000 using the antenna component 100 may receive the stronger signal; in addition, this can avoid setting up a plurality of millimeter wave antennas in a plurality of orientations respectively, reduce the cost of customer premises equipment 1000.

Specifically, the holder 10 may be made of a material such as plastic or metal that is not easily deformed, so that the holder 10 can stably support the millimeter wave antenna module 20. The millimeter wave antenna module 20 may be fixed to the support 10 by means of a screw thread, a snap, an adhesive, or the like.

The bracket 10 may be fixedly connected to the rotating member 92 by means of threads, snap fit, adhesive, etc. The support frame 10 may also be formed integrally with the rotation member 92, so that the support frame 10 and the rotation member 92 are fixedly connected together.

The operating frequency band of the millimeter-wave antenna module 20 is different from that of the above antenna unit 200. That is to say, the client terminal device 1000 according to the embodiment of the present application may operate in two different frequency bands, and may implement at least two operating modes. Such as a mode for receiving millimeter wave signals and a mode for receiving signals below 6 GHz. When the client terminal apparatus 1000 is used for transceiving millimeter-wave signals, the antenna unit 200 may be omitted.

The millimeter wave antenna module 20 is used for transmitting and receiving millimeter waves (millimeter wave). The millimeter wave is an electromagnetic wave with a wavelength of 1-10 mm. Millimeter waves are easily absorbed, so that the millimeter waves are attenuated in the propagation process. In addition, the lobe of the millimeter wave is small, so that the propagation range of the millimeter wave is small, and the directivity is strong. The millimeter wave antenna module 20 can obtain a millimeter wave signal having a strong signal at a predetermined position.

Rotating member 92 may rotate millimeter wave antenna module 20 via bracket 10 such that millimeter wave antenna module 20 may receive and transmit signals toward a predetermined direction, such that millimeter wave antenna module 20 may receive and transmit signals of stronger millimeter waves. In addition, the millimeter wave antenna module 20 receives and transmits millimeter wave signals, so that the client terminal device 1000 according to the present embodiment can implement a function of receiving and transmitting 5G signals.

It should be noted that the rotation of the rotation member 92 about multiple axes means that the rotation member 92 rotates about at least two axes arranged crosswise with respect to the fixed member 91, so that the millimeter wave antenna module can also rotate about the at least two axes.

In the present embodiment, the rotating member 92 rotates about the first axis 101 and the second axis 102 with respect to the fixed member 91 so that the millimeter wave antenna module 20 can rotate about the first axis 101 and the second axis 102, the first axis 101 and the second axis 102 being arranged to intersect. It should be noted that, the first axis 101 and the second axis 102 are arranged to intersect, which may mean that the first axis 101 and the second axis 102 are not perpendicular, or that the first axis 101 and the second axis 102 are perpendicular. In the present embodiment, the first axis 101 is perpendicular to the second axis 102. Of course, in other embodiments, the rotational member 92 may rotate about three axes.

Rotation of millimeter-wave antenna module 20 about first axis 101 and second axis 102 means that the angle through which millimeter-wave antenna module 20 rotates about first axis 101 may be 360 degrees or less than 360 degrees, and the angle through which millimeter-wave antenna module 20 rotates about second axis 102 may be 360 degrees or less than 360 degrees.

In the embodiment of the present application, the support 10 may drive the millimeter wave antenna module to rotate around two of the X axis, the Y axis, and the Z axis. The X axis, the Y axis and the Z axis are mutually perpendicular, the X axis and the Y axis are in the horizontal direction, and the Z axis is in the vertical direction. The positive directions of the X axis, the Y axis and the Z axis conform to the rule of right hand, namely, the Z axis is held by the right hand, and when the four fingers of the right hand turn to the positive Y axis at an angle of pi/2 from the positive X axis, the pointing direction of the thumb is the positive direction of the Z axis.

In the embodiment of the present application, the bracket 10 drives the millimeter wave antenna module 20 to rotate around the Z axis and the Y axis, as shown in fig. 7. Alternatively, the first axis 101 is oriented in the Z-axis direction, and the second axis 102 is oriented in the Y-axis direction.

In this embodiment, the angle through which the bracket 10 drives the millimeter wave antenna module 20 to rotate around the first axis 101 is 360 degrees. Of course, in other embodiments, the angle through which bracket 10 rotates millimeter-wave antenna module 20 about first axis 101 may be less than 360 degrees.

In addition, due to the limitation of the fixing member 91, the angle by which the bracket 10 drives the millimeter wave antenna module 20 to rotate around the second axis 102 is less than 360 degrees. For example, the angle at which the bracket 10 rotates the millimeter-wave antenna module 20 around the second axis 102 is ± 45 degrees. Of course, in other embodiments, the angle through which the bracket 10 rotates the millimeter-wave antenna module 20 around the second axis 102 may be 360 degrees.

As shown in fig. 8a and 8b, the bracket 10 rotates the millimeter wave antenna module 20, so that the millimeter wave antenna module 20 can rotate from a position facing away from the base station 1100 to a position facing the base station 1100, thereby improving the efficiency of signal transmission between the millimeter wave antenna module 20 and the base station 1100.

Note that, in order to further reduce the cost of the client terminal apparatus 1000, the client terminal apparatus 1000 may be one.

Referring to fig. 7, in some embodiments, millimeter-wave antenna module 20 may include a circuit board 21 and a millimeter-wave antenna 22. The millimeter wave antenna 22 is provided on the circuit board 21 and electrically connected to the circuit board 21. The circuit board 21 is fixed to the bracket 10. In this manner, the millimeter wave antenna module 20 may be fixed to the support 10 via the circuit board 21, so that the millimeter wave antenna 22 transmits and receives millimeter wave signals by rotating to a predetermined angle with the support 10.

Specifically, the circuit board 21 may be a rigid circuit board or a flexible circuit board. In the present embodiment, in order to improve the mounting stability of the circuit Board 21 and the millimeter wave antenna 22, the circuit Board 21 is a rigid circuit Board such as a Printed Circuit Board (PCB). The circuit board 21 may be fixed to the bracket 10 by means of screws, adhesive bonding, or the like.

The millimeter-wave antenna 22 is in the form of a sheet. The millimeter-wave antenna 22 may be fixed to the circuit board 21 by soldering. The millimeter wave antenna 22 may achieve signal transfer with the circuit board 21. For example, the circuit board 21 may transmit the signal received by the millimeter wave antenna 22 to the main circuit board 700.

Note that there is one millimeter wave antenna 22. In the case where the millimeter-wave antenna 22 is electrically connected to the main circuit board 700 by a wire, the circuit board 21 may be omitted.

As shown in fig. 7, in some embodiments, millimeter-wave antenna 22 includes first side 221 and second side 222 disposed opposite to each other, and millimeter-wave antenna 22 transmits and receives signals through first side 221. Millimeter-wave antenna module 20 includes heat dissipation element 40, and heat dissipation element 40 is disposed on second face 222.

In this way, heat dissipation element 40 may quickly dissipate heat generated by millimeter-wave antenna 22 to reduce the temperature of millimeter-wave antenna 22, thereby ensuring normal operation of millimeter-wave antenna 22.

It is understood that the orientation of the first face 221 of the millimeter-wave antenna 22 is also changed during the rotation of the support 10, and the millimeter-wave signal can be efficiently received when the orientation of the first face 221 of the millimeter-wave antenna 22 is rotated to a predetermined position. In the present embodiment, the orientation of the millimeter wave antenna module 20 is the orientation of the first surface 221.

The heat dissipation element 40 may be fixed to the second surface 222 by welding or bonding. In order to improve the thermal conductivity between the heat dissipation element 40 and the second surface 222, an element with better thermal conductivity, such as a thermal conductive silicone grease, may be disposed between the heat dissipation element 40 and the second surface 222.

Specifically, the heat radiating member 40 includes a base 41 and a plurality of heat radiating fins 42 extending from the base 41. The plurality of fins 42 are provided at intervals. The substrate 41 is sheet-shaped and attached to the second surface 222. Thus, the plurality of heat dissipation fins 42 can increase the heat dissipation area of the heat dissipation element 40, and improve the heat dissipation performance of the heat dissipation element 40.

In the embodiment of the present application, the first surface 221 may receive a signal within a predetermined angle range with a normal line of the first surface 221 as a center line. This can increase the range over which the first surface 221 can transmit and receive signals.

It should be noted that, in the initial position, the first surface 221 may be vertically disposed, or may be obliquely disposed or inclined. The orientation of the initial position of the first surface 221 is not limited herein.

Of course, in other embodiments, the avoiding space 211 may be isolated from the edge of the circuit board 21. The shape of the escape space 211 may be specifically set according to the shape of the heat radiating member 40.

In the present embodiment, the heat dissipating element 40 is partially accommodated in the escape space 211. Of course, in other embodiments, when the volume of the heat dissipating element 40 is smaller than the volume of the escape space 211, the heat dissipating element 40 may be completely accommodated in the escape space 211.

Specifically, to reduce resistance to rotation of spherical portion 922, spherical portion 922 and mounting hole 912 may be clearance fit. The sides of the mounting hole 912 may be spherical surfaces that mate with the spherical portion 922.

In this way, the driving device 110 can control the rotation process of the rotating member 92 automatically.

The driving device 110 may drive the rotation member 92 to rotate by an electromagnetic method or the like. In one example, the driving device 110 may include a flexible memory alloy wire that pulls the rotator 92 in various directions, and the amount of deformation of the flexible memory alloy wire may be changed by applying different voltages to the flexible memory alloy wire, so as to change the rotational deflection of the rotator 92, and thus the orientation of the millimeter wave antenna module 20.

It should be noted that, the first sub-device 30 is accommodated in the first accommodating space 51, which may mean that the first sub-device 30 is entirely accommodated in the first accommodating space 51, or that the first sub-device 30 is partially accommodated in the first accommodating space 51. In the present embodiment, the first sub-device 30 is entirely housed in the first housing space 51.

The millimeter wave antenna module 20 is fixed to the support portion 12. The rotary shaft 11 is fixedly connected to the rotary member 92. Thus, the rotating member 92 can rotate the bracket 10 via the rotating shaft 11.

In one example, the rotating shaft portion 11 and the supporting portion 12 are integrally formed. In the present embodiment, the support portion 12 has a bifurcated structure. In other embodiments, the support portion 12 may have other structures as long as the support portion 12 can stably mount the millimeter wave antenna module 20.

Referring to fig. 11-12, in some embodiments, the antenna assembly 100 may include a position sensor 60, and the position sensor 60 is used to detect the rotation angle of the bracket 10. As such, the position at which the stand 10 is rotated can be accurately controlled according to the data fed back by the position sensor 60, thereby allowing the millimeter wave antenna module 20 to be precisely rotated to a predetermined position to efficiently transmit and receive signals.

In one example, a control command for controlling the support 10 to rotate 20 degrees around the first axis 101101 may be sent to the first motor 31, and the first motor 31 operates to rotate the support 10 around the first axis 101 through the first magnetic member 32 after receiving the control command. If the position sensor 60 detects that the angle of the support 10 actually rotating around the first axis 101 is 25 degrees, which indicates that the support 10 is rotating excessively, the first motor 31 is controlled to drive the support 10 to rotate around the first axis 101 by 5 degrees, so that the support 10 with the millimeter wave antenna module 20 is located at a position with a better signal.

The magnetic encoder may sense a change in the magnetic field formed by the magnetic element 70 to determine the rotation angle of the rotator 92. It will be appreciated that since the rotatable member is fixedly connected to the bracket 10, by detecting the position of the rotatable member 92, the angle of rotation of the bracket 10 can be further determined.

For example, when the number of the position sensors 60 is two, one of the position sensors 60 may detect the angle of rotation of the support 10 about the first axis 101, and the other position sensor 60 may detect the angle of rotation of the support 10 about the second axis 102.
