[0002] This disclosure claims priority to the Chinese patent application filed with the State Intellectual Property Office on September 11, 2023, with application number CN202311163243.2 and invention name “Antenna adjustment device, antenna device, electronic device and control method thereof”. The entire contents of the application are incorporated by reference in this disclosure. Technical Field

[0003] The embodiments of the present disclosure relate to, but are not limited to, the field of communication technology, and in particular, to an antenna adjustment device, an antenna device, an electronic device, and a control method thereof. Background Art

[0004] Currently, there are two types of antennas used in terminals: omnidirectional antennas and directional antennas. A directional antenna transmits and receives electromagnetic wave signals strongly in one or several specific directions, but weakly in other directions.

[0005] To increase the signal reception range of directional antennas, existing technical solutions involve rotating them with a motor to adjust the direction of signal gain. However, spatial adjustment of the antenna requires both directional rotation and elevation adjustment. Directional rotation requires rotation adjustment around the X-axis, while elevation adjustment requires rotation adjustment around the Y- and Z-axes. This requires a motor for each rotation axis to adjust the antenna in the corresponding direction, which increases costs.

[0006] Moreover, it is understandable that in order to ensure that the antenna can be adjusted in three directions at any time, during the design, when one of the motors drives the antenna to rotate in a certain direction, the other two motors need to move synchronously. This leads to the need to consider the problem of motor routing during the design, making the internal structure of the antenna more complicated.

[0007] In addition, since multiple motors are used for separate driving, in order to achieve mutual matching between the two actions of directional antenna rotation and pitch angle adjustment, the system needs to receive the signals after the directional antenna rotation and the pitch angle adjustment in real time, and then perform comprehensive analysis and calculation before driving multiple motors to rotate separately. This increases the system's computing time on the one hand and the power consumption of the entire machine on the other.

[0008] Summary of the Invention

[0009] The embodiments of the present disclosure aim to at least solve the problems of complex structure and high cost of the adjustment device of the directional antenna in the prior art, and propose an antenna adjustment device, an antenna device, an electronic device and a control method thereof.

[0010] In the first aspect, an embodiment of the present disclosure discloses an antenna adjustment device, comprising: a rotating base, rotatably arranged around a first axis; a transmission mechanism, arranged on the rotating base, for installing an antenna assembly and driving the antenna assembly to rotate around a second axis relative to the rotating base; a driving mechanism, having a first position and a second position, and the driving mechanism switches between the first position and the second position by movement, wherein, in the first position, the driving mechanism cooperates with the rotating base to drive the rotating base to drive the antenna assembly to rotate around the first axis; in the second position, the driving mechanism disengages from the rotating base and cooperates with the transmission mechanism to drive the antenna assembly to rotate around the second axis relative to the rotating base.

[0011] In a second aspect, an embodiment of the present disclosure further discloses an antenna device, including an antenna assembly and the above-mentioned antenna adjustment device.

[0012] On the third aspect, the embodiment of the present disclosure also discloses a control method for the above-mentioned antenna device, which includes the following steps: obtaining the signal strength of the current position of the antenna component; comparing the obtained signal strength with the preset signal strength, and controlling the driving mechanism according to the comparison result.

[0023] To enable those skilled in the art to better understand the technical solutions of the present disclosure, the antenna adjustment device, antenna device, electronic device, and control method thereof provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0024] Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, but the example embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of this disclosure to those skilled in the art.

[0025] As shown in FIG. 1 and FIG. 2 , according to an embodiment of the present disclosure, an antenna adjustment device is disclosed, including: a rotating base 10 , a transmission mechanism 20 and a driving mechanism 40 .

[0026] The rotating base 10 is rotatably mounted about a first axis. The transmission mechanism 20 is mounted on the rotating base 10 and is used to mount the antenna assembly 30 and drive the antenna assembly 30 to rotate relative to the rotating base 10 about a second axis, with the first and second axes being perpendicular to each other. The drive mechanism 40 is movably mounted and has a first position and a second position, between which the drive mechanism 40 is shifted. In the first position, the drive mechanism 40 engages with the rotating base 10 to drive the rotating base 10 and the antenna assembly 30 to rotate about the first axis. In the second position, the drive mechanism 40 disengages from the rotating base 10 and engages with the transmission mechanism 20 to drive the antenna assembly 30 to rotate relative to the rotating base 10 about the second axis.

[0027] When the antenna adjustment device of the present disclosure is in use, as shown in FIG1 , the drive mechanism 40 can be first moved to the first position. At this point, the drive mechanism 40 engages with the rotating base 10 and disengages from the transmission mechanism 20. Consequently, the drive mechanism 40 drives the rotating base 10 to rotate about a first axis. The rotating rotating base 10 then drives the transmission mechanism 20 thereon to rotate about the first axis, thereby causing the antenna assembly 30 mounted on the transmission mechanism 20 to also rotate about the first axis. After the antenna assembly 30 rotates about the first axis by a predetermined angle, as shown in FIG2 , the drive mechanism 40 is moved to the second position. At this point, the drive mechanism 40 disengages from the rotating base 10 and engages with the transmission mechanism 20. In other words, the drive mechanism 40 does not drive the rotating base 10 to rotate, but only drives the transmission mechanism 20, causing the second drive mechanism 40 to drive the antenna assembly 30 to rotate relative to the rotating base 10 about the second axis.

[0028] As can be seen, the antenna adjustment device disclosed herein utilizes a movable drive mechanism 40 that cooperates with the rotating base 10 and transmission mechanism 20. By moving the drive mechanism 40 to engage with the rotating base 10 and transmission mechanism 20, the antenna assembly 30 can be independently rotated about the first or second axis. Compared to the prior art, the disclosed device has a simpler structure and utilizes a single motor to drive the drive mechanism 40, requiring fewer motors and reducing manufacturing costs.

[0029] It should be noted that in this embodiment, as shown in FIG1 , when the drive mechanism 40 moves to the first position, the drive mechanism 40 engages with the rotating base 10 while disengaging from the transmission mechanism 20. That is, in this embodiment, after the drive mechanism 40 moves to the first position, it only drives the rotating base 10 and does not drive the transmission mechanism 20. However, as shown in FIG2 , after the drive mechanism 40 moves to the second position, it only drives the transmission mechanism 20 and does not drive the rotating base 10. However, this is not limiting. In other embodiments (not shown), when the drive mechanism 40 moves to the first position, the drive mechanism 40 may engage with both the rotating base 10 and the transmission mechanism 20. That is, after the drive mechanism 40 moves to the first position, it can simultaneously drive the rotating base 10 and the transmission mechanism 20, causing the antenna assembly 30 to rotate about both the first and second axes. However, as shown in FIG2 , after the drive mechanism 40 moves to the second position, it only drives the transmission mechanism 20, causing the antenna assembly 30 to rotate only about the second axis. Both of the above-described embodiments utilize a movable drive mechanism 40 to change the coordination with the rotating base 10 and the transmission mechanism 20, thereby enabling the antenna assembly 30 to rotate about the first and second axes, or solely about the second axis. Therefore, these embodiments are all within the scope of protection of this disclosure. Compared to the prior art, the present disclosure has a simpler structure and utilizes only one motor to drive the drive mechanism 40, requiring fewer motors and reducing manufacturing costs.

[0030] In another embodiment of the present disclosure, as shown in FIG3 , a drive mechanism 40 includes a drive shaft 41, a drive gear 42, and a drive motor 43. The drive gear 42 is fixedly connected to the drive shaft 41, and the output shaft of the drive motor 43 is fixedly connected to the drive shaft 41 to drive the drive shaft 41 to rotate. The drive shaft 41 is disposed on the rotating base 10, and the axis of the drive shaft 41 is a first axis. The drive shaft 41 is movably disposed on the rotating base 10 along the first axis.

[0031] In the first position of the driving mechanism 40, the driving shaft 41 and the rotating base 10 are engaged in the upper limit position in the rotation direction of the driving shaft 41, and the driving gear 42 is disengaged from the transmission mechanism 20, so that the driving shaft 41 drives the rotating base 10 to rotate around the first axis; in the second position of the driving mechanism 40, the driving gear 42 and the transmission mechanism 20 are engaged in driving, and the driving shaft 41 is disengaged from the rotating base 10, so that the driving shaft 41 is rotatable in the circumferential direction relative to the rotating base 10.

[0032] It will be understood that in this embodiment, the drive mechanism 40 also moves along the first axis, and its first and second positions are also located in the direction of the first axis. When the drive mechanism 40 is in the first position, the position of the drive shaft 41 coincides with the positional engagement of the rotating base 10 in the direction of rotation of the drive shaft 41 (i.e., the circumferential direction of the drive shaft 41), allowing the drive shaft 41 to drive the rotating base 10 to rotate. At the same time, driven by the drive shaft 41, the drive gear 42 moves along the first axis to a position where it disengages from the transmission mechanism 20. Therefore, the drive gear 42 cannot drive the transmission mechanism 20, and the antenna assembly 30 rotates about the first axis along with the rotating base 10, and does not rotate about the second axis.

[0033] When the drive mechanism 40 moves along the first axis to the second position, the drive shaft 41 is positioned so that it is released from its restricted engagement with the rotating base 10 in the direction of rotation of the drive shaft 41 (i.e., the circumferential direction of the drive shaft 41). In other words, the drive shaft 41 can rotate about the first axis while the rotating base 10 does not rotate. Therefore, the antenna assembly 30 does not rotate about the first axis either. Simultaneously, driven by the drive shaft 41, the drive gear 42 moves along the first axis to a position that engages with the transmission mechanism 20, thereby enabling the transmission mechanism 20 to drive the antenna assembly 30 to rotate relative to the rotating base 10 about the second axis.

[0034] The antenna adjustment device disclosed herein utilizes a movable drive mechanism 40 that can independently drive the rotating base 10 and the transmission mechanism 20, thereby driving the antenna assembly 30 to rotate about a first axis or a second axis. In other words, the antenna assembly 30 can be adjusted in different directions using a single drive mechanism 40. While achieving the same function, this eliminates the need for other drive mechanisms 40, reduces the number of components used, and reduces costs. Furthermore, the reduced number of components simplifies the overall structure.

[0035] Specifically, as shown in Figure 3, a through hole 11 is provided on the rotating base 10 along the first axial direction, and the outer diameter of the drive shaft 41 is smaller than the inner diameter of the through hole 11, so that the drive shaft 41 can be movably passed through the through hole 11; a first limiting portion 411 is provided on the outer wall of the drive shaft 41, and a second limiting portion 111 is provided on the inner wall of the through hole 11 to cooperate with the first limiting portion 411.

[0036] In this embodiment, the first limiting portion 411 is a limiting protrusion, and the second limiting portion 111 is a limiting groove. As shown in FIG3 , the limiting protrusion is provided on the outer wall surface of the drive shaft 41 along the first axis direction, and the limiting groove extends from the first end to the second end of the through hole 11.

[0037] When the drive mechanism 40 is in the first position, the limiting protrusion fits neatly into the limiting groove, achieving a limiting fit in the rotational direction of the drive shaft 41 (circumferentially of the drive shaft 41), preventing relative rotation between the drive shaft 41 and the rotating base 10. When the drive shaft 41 rotates, the limiting protrusion abuts against the wall of the limiting groove, and the driving force of the drive shaft 41 is transmitted to the rotating base 10 through the limiting protrusion and the limiting groove, causing the rotating base 10 to rotate.

[0038] When the drive mechanism 40 is in the second position, the stop protrusion and the stop slot are mutually reciprocating. That is, the stop protrusion is located outside the stop slot, and the drive shaft 41 cannot transmit the driving force to the rotating base 10 through the stop protrusion and the stop slot. Therefore, the drive shaft 41 can only rotate on its own and cannot drive the transmission base to rotate, thereby achieving rotation of the antenna assembly 30 relative to the rotating base 10.

[0039] It should be noted that in this embodiment, the first limiting portion 411 is a limiting protrusion and the second limiting portion 111 is a limiting groove, but this is not restrictive. In some other embodiments not shown in the figures, the first limiting portion 411 can be a limiting groove, the second limiting portion 111 can be a limiting protrusion, or the first limiting portion 411 and the second limiting portion 111 can also be other structures. As long as the structure can achieve the limiting fit of the drive mechanism 40 in the rotation direction of the drive shaft 41 when the drive mechanism 40 is in the first position and the mutual avoidance of the drive mechanism 40 in the second position, it is within the scope of protection of this disclosure.

[0040] As shown in FIG. 3 , in this embodiment, the transmission mechanism 20 includes a first transmission gear 21 , a mounting seat 22 , a rotating bracket 23 , a second transmission gear 24 and a mounting portion 25 .

[0041] The first transmission gear 21 is rotatably connected to the rotating base 10 for engaging with the driving gear 42. Specifically, as shown in FIG3 , the mounting portion 25 is provided on the rotating base 10, and the first transmission gear 21 is rotatably connected to the mounting portion 25.

[0042] It should be noted that in the embodiment shown in Figure 3, the mounting portion 25 is a fixed column fixedly connected to the rotating base 10 along the first axis. A bearing is fixedly connected to the fixed column, and the first transmission gear 21 is fixedly connected to the bearing, thereby being rotatably connected to the mounting portion 25 via the bearing. However, this is not restrictive. In other embodiments not shown in the figures, the mounting portion 25 can also be a bracket, a rotating shaft, or other structures. As long as the structure can enable the first transmission gear 21 to rotate along the first axis, it is within the scope of protection of this disclosure.

[0043] The mounting base 22 is connected to the rotating base 10. The mounting base 22 is located on the outer periphery of the rotating base 10 and can rotate with the rotating base 10. In other words, the mounting base 22 and the rotating base 10 cannot rotate relative to each other in the rotation direction of the drive shaft 41, and the mounting base 22 cannot rotate relative to the rotating base 10.

[0044] As shown in Figure 3, the rotating bracket 23 is rotatably mounted on the mounting base 22. The rotating bracket 23 rotates relative to the mounting base 22 about a second axis. In this embodiment, since the mounting base 22 and the rotating base 10 cannot rotate relative to each other, the rotating bracket 23 also rotates relative to the rotating base 10 about the second axis. The rotating bracket 23 is used to mount the antenna assembly 30. The second transmission gear 24 is drivingly connected to the rotating bracket 23 and is configured to mesh with the first transmission gear 21 to drive the antenna assembly 30 to rotate about the second axis.

[0045] Specifically, as shown in Figure 3, the mounting base 22 includes: a support plate 221 and a support column 222 fixedly connected to the support plate 221, the support plate 221 is connected to the rotating base 10, there are two support columns 222, the two support columns 222 are arranged at intervals along the second axis direction, and mounting holes 223 are provided on the two support columns 222, and the rotating bracket 23 is rotatably arranged between the two support columns 222.

[0046] The rotating bracket 23 comprises a transmission shaft 231, a connecting arm 232, and a mounting plate 233. Both ends of the transmission shaft 231 are positioned within the mounting holes 223, where bearings are fixedly connected. The transmission shaft 231 forms a rotational connection with the support columns 222 via the bearings, with the axis of the transmission shaft 231 aligned along the second axis. This allows the transmission shaft 231 to rotate relative to the rotating base 10 about the second axis. Two connecting arms 232 are provided, each with its first end fixedly connected to the transmission shaft 231 and its second end fixedly connected to the mounting plate 233 for mounting the antenna assembly 30. A second transmission gear 24 is fixedly connected to the transmission shaft 231. The second transmission gear 24 drives the transmission shaft 231 to rotate, which in turn drives the connecting arms 232 and the mounting plate 233 to rotate between the two support columns 222, thereby enabling the antenna assembly 30 to rotate relative to the rotating base 10 about the second axis.

[0047] In another embodiment of the present disclosure, as shown in FIG4 , the drive gear 42, the first transmission gear 21, and the second transmission gear 24 are all bevel gears. The drive gear 42 rotates about a first axis, while the first transmission gear 21 rotates along the same axis as the first axis, and the second transmission gear 24 rotates along the second axis. The first axis and the second axis are perpendicular, and the change in transmission direction is achieved through the interaction between the first transmission gear 21 and the second transmission gear 24.

[0048] In this embodiment, in order to enable the antenna assembly 30 to rotate 360° around the second axis, the length of the support column 222 must be greater than the length of the connecting arm 232, and the width between the two support columns 222 must be greater than the width of the antenna assembly 30, so that the rotating bracket 23 and the antenna assembly 30 can pass through the two support columns 222.

[0049] In the first position of the driving mechanism 40, the first limiting portion 411 on the driving shaft 41 is limitedly engaged with the second limiting portion 111 on the rotating base 10. At the same time, the driving gear 42 is disengaged from the first transmission gear 21, so that the driving shaft 41 can only drive the rotating base 10 to rotate around the first axis, and the driving gear 42 will not drive the first transmission gear 21 to rotate. Therefore, the rotating base 10 drives the antenna assembly 30 to rotate synchronously around the first axis through the mounting base 22 and the rotating bracket 23.

[0050] In the second position of the drive mechanism 40, the first stopper 411 on the drive shaft 41 disengages from the second stopper 111 on the rotating base 10. Simultaneously, the drive gear 42 engages with the first transmission gear 21, driving the first transmission gear 21 to rotate. The first transmission gear 21, which rotates about its own axis, then engages with the second transmission gear 24. Because the drive gear 42, the first transmission gear 21, and the second transmission gear 24 are all bevel gears, the direction of rotation can be changed from the first axis to the second axis. The second transmission gear 24, which rotates about the second axis, drives the rotating bracket 23 to rotate, causing the antenna assembly 30 to rotate about the second axis relative to the rotating base 10.

[0051] It can be seen from this that the antenna adjustment device disclosed in the present invention can change the direction of the rotation axis of the driving force by setting the second transmission mechanism 20, so that it can cooperate with the driving mechanism 40 to realize the function of rotating the antenna component 30 around the second axis relative to the rotating base 10, so that there is no need to set up a separate driving mechanism 40. The adjustment of the antenna component 30 in different directions is achieved by sharing a driving mechanism 40. While ensuring the same function, other driving mechanisms 40 are eliminated, fewer structural components are used, and costs are reduced. In addition, due to the reduction in structural components, the overall structure is simpler.

[0052] It should be noted that, in the embodiments shown in Figures 1 and 2, there are two mounting seats 22, rotating brackets 23 and second transmission gears 24, and accordingly, there are two second axes, namely the first sub-axis and the second sub-axis, and the first sub-axis and the second sub-axis are both perpendicular to the direction of the first axis.

[0053] Each mounting base 22 is provided with a rotating bracket 23 and a second transmission gear 24. One rotating bracket 23 rotates relative to its mounting base 22 about a first sub-axis, while the other rotating bracket 23 rotates relative to its mounting base 22 about a second sub-axis. In other words, one rotating bracket 23 rotates relative to the rotating base 10 about the first sub-axis, while the other rotating bracket 23 rotates relative to the rotating base 10 about the second sub-axis. The two mounting bases 22 are arranged at 90° angles around the outer circumference of the rotating base 10, meaning that the first and second sub-axes are perpendicular to each other.

[0054] With this arrangement, an antenna assembly 30 can be provided on each rotating bracket 23, thereby realizing rotation around three corresponding mutually perpendicular axes in three-dimensional space, so that the antenna assembly 30 can search for signal strength in all directions, receive and send signals without blind spots, and improve the comprehensiveness of the signal adjustment range.

[0055] It should be noted that in this embodiment, there are two mounting seats 22, two rotating brackets 23, and two second transmission gears 24, but this is not restrictive. In other embodiments not shown in the figures, there may be only one mounting seat 22, one rotating bracket 23, and one second transmission gear 24, or more than one. In other words, as long as multiple mounting seats 22 are spaced apart on the outer periphery of the rotating base 10, each mounting seat 22 is provided with a rotating bracket 23 and a second transmission gear 24, and the second axes of all rotating brackets 23 are perpendicular to the first axis, this is within the scope of protection of the present disclosure.

[0056] In another embodiment shown in FIG4 , the mounting seat 22 is movable relative to the rotating base 10 in the direction of the second axis, and the mounting seat 22 engages or disengages the first transmission gear 21 and the second transmission gear 24 by moving; in the rotation direction of the rotating base 10 , the mounting seat 22 and the rotating base 10 are limitedly engaged.

[0057] In this way, for example: when the antenna assembly 30 rotating around the first sub-axis is adjusted to the optimal position, the mounting seat 22 corresponding to the antenna assembly 30 can be moved to separate the second transmission gear 24 on the cover mounting seat 22 from the first transmission gear 21, so that the antenna assembly 30 stops rotating, while the mounting seat 22 corresponding to the antenna assembly 30 rotating around the second sub-axis remains in the same position, so that the antenna assembly 30 can continue to rotate around the second sub-axis until it is adjusted to the optimal position.

[0058] Specifically, as shown in Figure 4, the antenna adjustment device also includes: a first sliding part 51 and a second sliding part 52. In this embodiment, the first sliding part 51 is a slide rail, and the second sliding part 52 is a slide groove. The slide rail is fixedly arranged on the rotating base 10 along the second axis direction; the slide groove is fixedly arranged at the bottom of the support plate 221 of the mounting seat 22, and the slide groove and the slide rail slide together in the direction of the second axis, and the slide groove and the slide rail are upper-limited in the rotation direction of the rotating base 10.

[0059] When the antenna assembly 30 needs to stop rotating, the mounting base 22 slides along the slide rail away from the rotating base 10, thereby disengaging the first transmission gear 21 from the second transmission gear 24; when the antenna assembly 30 needs to rotate, the mounting base 22 slides along the slide rail close to the rotating base 10, thereby engaging the first transmission gear 21 from the second transmission gear 24.

[0060] In this embodiment, the first sliding portion 51 is a slide rail, and the second sliding portion 52 is a slide groove. However, this is not restrictive. In other embodiments not shown, the first sliding portion 51 may also be a slide groove, and the second sliding portion 52 may be a slide rail. In other words, any structure that allows the second sliding portion 52 to slide with the first sliding portion 51 in the direction of the second axis and to limit the rotation of the rotating base 10 is within the scope of protection of this disclosure.

[0061] As shown in FIG4 , the antenna adjustment device further includes a first driving assembly 70 , which is respectively connected to the rotating base 10 and the mounting base 22 , and is used to drive the mounting base 22 to move relative to the rotating base 10 in the direction of the second axis.

[0062] In this embodiment, the first driving assembly 70 includes a first magnet 71 and a second magnet 72. The first magnet 71 is disposed on the rotating base 10 and the second magnet 72 is disposed on the mounting base 22. The positions of the first magnet 71 and the second magnet 72 correspond to each other.

[0063] It is understood that the first magnet 71 and the second magnet 72 are electromagnets. By controlling the direction of the current, the first drive assembly 70 can be placed in an attractive state and a repulsive state. Specifically, the electromagnet includes an iron core and an electromagnetic coil wound around the iron core. By controlling the direction of the current in the electromagnetic coil, the magnetic poles generated at both ends of the iron core can be reversed. During use, the first magnet 71 and the second magnet 72 are arranged relative to each other, so that the first end of the iron core of the first magnet 71 is opposite to the first end of the iron core of the second magnet 72. In the attractive state, the magnetic poles generated by the first end of the iron core of the first magnet 71 and the first end of the iron core of the second magnet 72 are opposite, thereby causing the first magnet 71 and the second magnet 72 to attract each other. In the repulsive state, the magnetic poles generated by the first end of the iron core of the first magnet 71 and the first end of the iron core of the second magnet 72 are the same, thereby causing the first magnet 71 and the second magnet 72 to repel each other.

[0064] In the attractive state, the first magnet 71 and the second magnet 72 attract each other, so that the first driving assembly 70 drives the mounting seat 22 and the rotating base 10 to approach each other, so that the first transmission gear 21 and the second transmission gear 24 engage; in the repulsive state, the first magnet 71 and the second magnet 72 repel each other, so that the first driving assembly 70 drives the mounting seat 22 and the rotating base 10 away from each other, so that the first transmission gear 21 and the second transmission gear 24 are separated.

[0065] The antenna adjustment device disclosed herein, by providing a first drive assembly 70, can change the position of the mounting base 22 relative to the rotating base 10, thereby controlling the engagement of the first transmission gear 21 and the second transmission gear 24, and thus controlling the rotation and stopping of the antenna assembly 30. By combining multiple mounting bases 22 and antenna assemblies 30, the independent rotation of antenna assemblies 30 in two different directions can be controlled, allowing the antenna assemblies 30 in corresponding directions to stop promptly when adjusted to the optimal position without interfering with each other. Compared to the prior art, the first drive assembly 70 disclosed herein has a simpler structure, lower cost, and lighter weight.

[0066] In another embodiment of the present disclosure as shown in FIG. 5 , an antenna device is also disclosed, including: a housing 80 , a support mechanism 60 , an antenna assembly 30 , the above-mentioned antenna adjustment device, and a second driving assembly 90 .

[0067] A support structure is provided inside the shell 80, and the rotating base 10 is rotatably provided on the support mechanism inside the shell 80; the second driving assembly 90 is provided in the shell 80, and the second driving assembly 90 is driven and connected to the driving mechanism 40 to drive the driving mechanism 40 to move between the first position and the second position.

[0068] The support mechanism 60 is fixedly connected in the shell 80, and the rotating base 10 is rotatably set on the support mechanism 60; the second driving assembly 90 is set in the shell 80, and the second driving assembly 90 is drivingly connected to the driving mechanism 40 to drive the driving mechanism 40 to move between the first position and the second position.

[0069] Specifically, as shown in Figure 5, the support mechanism 60 includes a support sleeve 61 and a support ring 62. The support sleeve 61 is fixedly connected to the housing 80; the support ring 62 is rotatably mounted on the outer wall of the support sleeve 61 and is fixedly connected to the rotating base 10. In this embodiment, the axis of the support sleeve 61 is the first axis. A bearing is fixedly connected to the support sleeve 61, and the support ring 62 is fixedly connected to the bearing, thereby enabling rotation relative to the support sleeve 61. By fixedly connecting the rotating base 10 to the support ring 62, the rotating base 10 can be supported while enabling the rotating base 10 to rotate along the first axis within the housing 80.

[0070] In one embodiment shown in Figure 6 , the second drive assembly 90 includes a third magnet 91 and a fourth magnet 92. The third magnet 91 is fixedly connected to the drive motor 43; the fourth magnet 92 is fixedly connected to the rotating base 10, with the position of the third magnet 91 corresponding to the position of the fourth magnet 92.

[0071] It is understood that the third magnet 91 and the fourth magnet 92 are electromagnets, and that the second drive assembly 90 can be placed in an attractive or repulsive state by controlling the direction of the current. Specifically, the electromagnet includes an iron core and an electromagnetic coil wound around the iron core. By controlling the direction of the current flowing through the electromagnetic coil, the magnetic poles generated at both ends of the iron core can be reversed.

[0072] During use, the third magnet 91 and the fourth magnet 92 are positioned relative to each other, with the first end of the iron core of the third magnet 91 facing the first end of the iron core of the fourth magnet 92. In an attractive state, the first end of the iron core of the third magnet 91 and the first end of the iron core of the fourth magnet 92 produce opposite magnetic poles, thereby attracting the third magnet 91 and the fourth magnet 92. In a repulsive state, the first end of the iron core of the third magnet 91 and the first end of the iron core of the fourth magnet 92 produce the same magnetic poles, thereby repelling the third magnet 91 and the fourth magnet 92.

[0073] In the attractive state, the second drive assembly 90 drives the drive mechanism 40 to move to the first position, the drive shaft 41 and the rotating base 10 are engaged in the upper limit position in the rotation direction of the drive shaft 41, and the drive gear 42 is disengaged from the transmission mechanism 20, so that the drive shaft 41 drives the rotating base 10 to rotate around the first axis.

[0074] In the repulsive state, the second drive assembly 90 drives the drive mechanism 40 to move to the second position, the drive gear 42 is driven to cooperate with the transmission mechanism 20, and the drive shaft 41 is disengaged from the rotating base 10, so that the drive shaft 41 can rotate in the circumferential direction relative to the rotating base 10.

[0075] In order to ensure that the driving force of the second driving assembly 90 is more uniform and stable, in this embodiment, the third magnet 91 and the fourth magnet 92 are annular structures, and the centers of the third magnet 91 and the fourth magnet 92 are both located on the first axis.

[0076] In this embodiment, the antenna assembly 30 includes a reflector 31 and a radiation plate 32. The reflector 31 is disposed on the mounting plate 233 of the rotating bracket 23; the radiation plate 32 is disposed parallel to the reflector 31 and fixedly connected to the reflector 31.

[0077] In addition, for the convenience of operation, a reset button 81 is provided on the shell 80, and the reset button 81 is electrically connected to the first drive component 70. The reset button 81 can be used to make the first drive component 70 enter an attractive state, so that the first transmission gear 21 and the second transmission gear 24 engage for the next adjustment.

[0078] As shown in FIG7 and FIG8 , the present disclosure further discloses a control method for the above-mentioned antenna device, the control method comprising the following steps:

[0079] S10: Obtaining the signal strength of the current position of the antenna assembly 30;

[0080] S20: Compare the acquired signal strength with the preset signal strength, and control the driving mechanism 40 according to the comparison result.

[0081] Furthermore, step S20 specifically includes the following steps:

[0082] S21: When the signal strength is greater than the preset signal strength, the driving mechanism 40 is controlled to stop rotating;

[0083] S22: When the signal strength is less than or equal to the preset signal strength, the driving mechanism 40 is controlled to drive the antenna assembly 30 to rotate along the first axis.

[0084] Furthermore, after step S22, the control method further includes the following steps:

[0085] S23: After the antenna assembly 30 rotates along the first axis by a preset angle, obtaining the signal strength of the antenna assembly 30 in real time;

[0086] S24: Compare the signal strength acquired in real time with the preset signal strength, and selectively control the driving mechanism 40 to drive the antenna assembly 30 to rotate along the second axis according to the comparison result.

[0087] Furthermore, step S24 specifically includes the following steps:

[0088] S241: When the signal strength is greater than the preset signal strength, controlling the antenna assembly 30 to maintain the current position;

[0089] S242: When the signal strength is less than or equal to the preset signal strength, controlling the driving mechanism 40 to drive the antenna assembly 30 to rotate along the second axis;

[0090] S243: After the antenna assembly 30 rotates to the starting position, the driving mechanism 40 is controlled to move to the first position and the antenna assembly 30 is controlled to rotate along the first axis, and the process returns to step S23.

[0091] The control method of the antenna device disclosed in the present invention, in conjunction with the antenna device, can realize the rotation and pitch angle adjustment of multiple antenna components 30 based on the use of a set of drive motors 43 and drive shafts 41, which on the one hand reduces the cost of the entire machine and the complexity of the mechanism; on the other hand, since it is driven by a single motor, the time for system analysis and calculation is reduced, and the power consumption of the entire machine is also reduced.

[0092] It should be noted that step S23 includes two embodiments:

[0093] In one embodiment, after the antenna assembly 30 rotates along the first axis by a preset angle, the driving mechanism 40 is still in the first position, but the driving motor 43 stops rotating. The signal strength of the antenna assembly 30 is first obtained, and the next step is determined based on the signal strength.

[0094] Therefore, in this embodiment, when the signal strength is greater than the preset signal strength, it indicates that the antenna assembly 30 is in a relatively good signal reception position at this time. Therefore, the drive mechanism 40 does not need to move to the second position, but instead maintains the current position. Then, when the signal strength changes or the device is restarted and the position of the antenna assembly 30 needs to be readjusted, since the drive mechanism 40 is in the first position, when executing step S22 of this embodiment, it is not necessary to move the drive mechanism 40. Instead, the drive mechanism 40 can be directly controlled to directly drive the antenna assembly 30 to rotate about the first axis.

[0095] When the signal strength is less than or equal to the preset signal strength, the driving mechanism 40 needs to move to the second position to drive the antenna assembly 30 to rotate along the second axis until the signal strength is greater than the preset signal strength. The driving mechanism 40 stops rotating or returns to step S23 after the antenna assembly 30 rotates around the second axis once.

[0096] In another embodiment, after the antenna assembly 30 rotates along the first axis by a predetermined angle, the drive mechanism 40 is controlled to move to a second position and drive the antenna assembly 30 to rotate along the second axis. Simultaneously, the signal strength of the antenna assembly 30 is acquired in real time, and the next step is determined based on the signal strength. In other words, this embodiment differs from the previous embodiment in that, in this embodiment, the rotation of the antenna assembly 30 about the second axis and the acquisition of signal strength occur simultaneously.

[0097] Therefore, in this embodiment, when the signal strength is greater than the preset signal strength, the drive mechanism 40 is required to stop driving the antenna assembly 30 to rotate about the second axis so that the antenna assembly 30 maintains its current position. Then, when the signal strength changes or the device is restarted and the position of the antenna assembly 30 needs to be readjusted, since the drive mechanism 40 is in the second position, when executing step S22 of this embodiment, the drive mechanism 40 needs to be controlled to move to the first position to drive the antenna assembly 30 to rotate along the first axis.

[0098] When the signal strength is less than or equal to the preset signal strength, the driving mechanism 40 drives the antenna assembly 30 to rotate along the second axis until the signal strength is greater than the preset signal strength. The driving mechanism 40 stops rotating or returns to step S23 after the antenna assembly 30 rotates around the second axis once.
