Description

Technical Field

[0001] The present invention relates 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

[0002] Currently, there are two types of antennas used in terminals: omnidirectional antennas and directional antennas. A directional antenna is one that transmits and receives electromagnetic wave signals very strongly in one or several specific directions, but very weak in other directions.

[0003] In order to increase the range of directional antennas receiving signals, the existing technical solution is to rotate the directional antenna driven by a motor to adjust the direction of signal gain. However, the spatial adjustment of the antenna requires directional rotation and pitch angle adjustment, where directional rotation requires rotation adjustment with the X axis as the rotation axis, and pitch angle adjustment requires rotation adjustment with the Y axis and Z axis respectively. This results in the need to set a motor for each rotation axis to realize the rotation adjustment of the antenna in the corresponding direction, which will lead to increased costs.

[0004] Moreover, it is understandable that in order to ensure that the antenna can be adjusted in three directions at any time,

[0005] 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 requires considering the motor routing during the design, making the internal structure of the antenna more complicated.

[0006] 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 signal after the directional antenna rotation and the signal after the pitch angle adjustment in real time, and then drive multiple motors to rotate separately after comprehensive analysis and calculation. This increases the system's computing time on the one hand, and increases the power consumption of the entire machine on the other. Summary of the invention

[0007] The embodiments of the present invention aim to at least solve the problem 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.

[0008] In a first aspect, an embodiment of the present invention 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, the driving mechanism switching between the first position and the second position by movement; 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.

[0009] In a second aspect, an embodiment of the present invention further discloses an antenna device, including an antenna assembly and the above-mentioned antenna adjustment device.

[0010] In a third aspect, an embodiment of the present invention further discloses a control method for the above-mentioned antenna device, the control method comprising 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.

[0011] In a fourth aspect, an embodiment of the present invention further discloses an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the above-mentioned control method.

[0012] The antenna adjustment device of the present invention is provided with a movable driving mechanism and cooperates with a rotating base and a transmission mechanism, and the driving mechanism can be moved to change the cooperation mode with the rotating base and the transmission mechanism, so that the antenna assembly can rotate around the first axis and the second axis respectively or rotate around the second axis alone. Compared with the prior art, the structure of the present invention is simpler, and only one motor is used to drive the driving mechanism to rotate, and the number of motors is reduced, thereby reducing the manufacturing cost.

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

[0024] Example embodiments will be described more fully below 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. On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete and to enable those skilled in the art to fully understand the scope of the present disclosure.

[0025] like Figure 1 and Figure 2 An embodiment of the present invention shown in FIG. 1 discloses an antenna adjustment device, including a rotating base 10 , a transmission mechanism 20 and a driving mechanism 40 .

[0026] The rotating base 10 is rotatably arranged around a first axis; the transmission mechanism 20 is arranged on the rotating base 10, and is used to install the antenna assembly 30 and drive the antenna assembly 30 to rotate around a second axis relative to the rotating base 10, and the first axis and the second axis are perpendicular to each other; the driving mechanism 40 is movably arranged, and has a first position and a second position, and the driving mechanism 40 switches between the first position and the second position by moving. In the first position, the driving mechanism 40 cooperates with the rotating base 10 to drive the rotating base 10 to drive the antenna assembly 30 to rotate around the first axis. In the second position, the driving mechanism 40 disengages from the rotating base 10 and cooperates with the transmission mechanism 20 to drive the antenna assembly 30 to rotate around the second axis relative to the rotating base 10.

[0027] When the antenna adjustment device of the present invention is used, Figure 1 As shown, the driving mechanism 40 can be moved to the first position first. At this time, the driving mechanism 40 is drivingly matched with the rotating base 10, and at the same time, the driving mechanism 40 is disengaged from the transmission mechanism 20. Therefore, the driving mechanism 40 drives the rotating base 10 to rotate around the first axis, and the rotating rotating base 10 drives the transmission mechanism 20 thereon to rotate around the first axis, thereby causing the antenna assembly 30 installed on the transmission mechanism 20 to rotate around the first axis. After the antenna assembly 30 rotates around the first axis by a preset angle, as shown in FIG. Figure 2 As shown, the driving mechanism 40 is moved to the second position. At this time, the driving mechanism 40 is disengaged from the rotating base 10 and is driven by the transmission mechanism 20. That is to say, the driving mechanism 40 will not drive the rotating base 10 to rotate, but will only drive the transmission mechanism 20, so that the second driving mechanism 40 drives the antenna assembly 30 to rotate around the second axis relative to the rotating base 10.

[0028] It can be seen that the antenna adjustment device of the present invention can be equipped with a movable driving mechanism 40 and cooperate with the rotating base 10 and the transmission mechanism 20, and the antenna assembly 30 can be rotated around the first axis or the second axis by moving the driving mechanism 40 to cooperate with the rotating base 10 and the transmission mechanism 20. Compared with the prior art, the structure of the present invention is simpler, and only one motor is used to drive the driving mechanism 40 to rotate, and the number of motors is reduced, thereby reducing the manufacturing cost.

[0029] It should be noted that, in this embodiment, Figure 2As shown, when the driving mechanism 40 moves to the first position, the driving mechanism 40 cooperates with the rotating base 10, and at the same time, the driving mechanism 40 is disengaged from the transmission mechanism 20, that is, in this embodiment, after the driving mechanism 40 moves to the first position, it only drives the rotating base 10 to rotate, and does not drive the transmission mechanism 20, and after the driving mechanism 40 moves to the second position, it only drives the transmission mechanism 20, and does not drive the rotating base 10 to rotate. However, this is not restrictive. In some other embodiments not shown in the figure, when the driving mechanism 40 moves to the first position, the driving mechanism 40 can cooperate with the rotating base 10 and the transmission mechanism 20 at the same time, that is, after the driving mechanism 40 moves to the first position, it can drive the rotating base 10 to rotate while also driving the transmission mechanism 20, so that the antenna assembly 30 rotates around both the first axis and the second axis, and after the driving mechanism 40 moves to the second position, it only drives the transmission mechanism 20, so that the antenna assembly 30 rotates only around the second axis. Both of the above embodiments can change the matching mode with the rotating base 10 and the transmission mechanism 20 by moving the driving mechanism 40, so that the antenna assembly 30 can rotate around the first axis and the second axis respectively, or rotate around the second axis alone. Therefore, the above embodiments are within the protection scope of the present invention. Compared with the prior art, the structure of the present invention is simpler, and only one motor is used to drive the driving mechanism 40 to rotate, and the number of motors is reduced, which reduces the manufacturing cost.

[0030] In such Figure 3 In another embodiment of the present invention shown, the driving mechanism 40 includes: a driving shaft 41, a driving gear 42 and a driving motor 43, the driving gear 42 is fixedly connected to the driving shaft 41, and the output shaft of the driving motor 43 is fixedly connected to the driving shaft 41 to drive the driving shaft 41 to rotate. The driving shaft 41 is set on the rotating base 10 through, the axis of the driving shaft 41 is the first axis, and the driving shaft 41 is movably set 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, and the driving shaft 41 is disengaged from the rotating base 10, so that the driving shaft 41 can rotate in the circumferential direction relative to the rotating base 10.

[0032] It can be understood that, in the present embodiment, the driving mechanism 40 also moves along the first axis, and its first position and second position are also located in the direction of the first axis. When the driving mechanism 40 is located in the first position, the position of the driving shaft 41 is exactly matched with the rotating base 10 in the rotation direction of the driving shaft 41 (i.e., in the circumferential direction of the driving shaft 41), so that the driving shaft 41 can drive the rotating base 10 to rotate. At the same time, driven by the driving shaft 41, the driving gear 42 moves along the first axis to a position where it is disengaged from the transmission mechanism 20. Therefore, the driving gear 42 cannot drive the transmission mechanism 20, and the antenna assembly 30 rotates around the first axis with the rotating base 10, and does not rotate around the second axis.

[0033] When the driving mechanism 40 moves to the second position along the first axis, the position of the driving shaft 41 is just such that the limiting fit between the driving shaft 41 and the rotating base 10 is released in the rotation direction of the driving shaft 41 (i.e., the circumferential direction of the driving shaft 41), that is, the driving shaft 41 can rotate around the first axis, while the rotating base 10 may not rotate, and therefore, the antenna assembly 30 will not rotate around the first axis; at the same time, driven by the driving shaft 41, the driving gear 42 moves along the first axis to a position that cooperates with the transmission mechanism 20, so that the antenna assembly 30 can be driven by the transmission mechanism 20 to rotate around the second axis relative to the rotating base 10.

[0034] The antenna adjustment device of the present invention is provided with a movable driving mechanism 40 so that it can drive the rotating base 10 and the transmission mechanism 20 respectively, thereby driving the antenna assembly 30 to rotate around the first axis or around the second axis. That is to say, the adjustment of the antenna assembly 30 in different directions shares a driving mechanism 40. While achieving the same function, other driving mechanisms 40 are omitted, fewer structural components are used, and the cost is reduced. In addition, due to the reduction in structural components, the overall structure is simpler.

[0035] Specifically, if Figure 3 As shown, a through hole 11 is provided on the rotating base 10 along the first axial direction, and the outer diameter of the driving shaft 41 is smaller than the inner diameter of the through hole 11, so that the driving shaft 41 can be movably inserted into the through hole 11; a first limiting portion 411 is provided on the outer wall of the driving shaft 41, and a second limiting portion 111 that cooperates with the first limiting portion 411 is provided on the inner wall of the through hole 11.

[0036] In this embodiment, the first limiting portion 411 is a limiting protrusion, and the second limiting portion 111 is a limiting groove. Figure 3 As shown, the limiting protrusion is arranged on the outer wall surface of the driving shaft 41 along the first axial direction, and the limiting groove extends from the first end to the second end of the through hole 11.

[0037] When the driving mechanism 40 is in the first position, the limiting protrusion just enters the limiting groove, realizing limiting cooperation in the rotation direction of the driving shaft 41 (circumferential direction of the driving shaft 41), so that the driving shaft 41 and the rotating base 10 cannot rotate relative to each other. When the driving shaft 41 rotates, the limiting protrusion abuts against the groove wall of the limiting groove, and the driving force of the driving shaft 41 is transmitted to the rotating base 10 through the limiting protrusion and the limiting groove, so that the rotating base 10 rotates.

[0038] When the driving mechanism 40 is located in the second position, the limiting protrusion and the limiting groove avoid each other, that is, the limiting protrusion is located outside the limiting groove, and the driving shaft 41 cannot transmit the driving force to the rotating base 10 through the limiting protrusion and the limiting groove. Therefore, the driving shaft 41 can only rotate by itself and cannot drive the transmission base to rotate, thereby realizing the rotation of the antenna assembly 30 relative to the rotating base 10.

[0039] It should be noted that, in the present embodiment, the first limit portion 411 is a limit groove, and the second limit portion 111 is a limit protrusion, but this is not restrictive. In some other embodiments not shown in the figure, the first limit portion 411 can be a limit groove, the second limit portion 111 can be a limit protrusion, or the first limit portion 411 and the second limit portion 111 can also be other structures. As long as the structure can achieve the limit positioning cooperation in the rotation direction of the driving shaft 41 when the driving mechanism 40 is in the first position and the driving mechanism 40 avoids each other in the second position, it is within the protection scope of the present invention.

[0040] like Figure 3 As shown, 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 and is used to mesh with the driving gear 42. Specifically, Figure 3 As shown, the mounting portion 25 is disposed 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 Figure 3 In the illustrated embodiment, the mounting portion 25 is a fixed column, which is fixedly connected to the rotating base 10 along the first axis direction, and a bearing is fixedly connected to the fixed column, and the first transmission gear 21 is fixedly connected to the bearing, so that it is rotatably connected to the mounting portion 25 through the bearing. However, this is not restrictive, and in some other embodiments not shown in the figure, the mounting portion 25 can also be a bracket, a rotating shaft, etc., as long as the structure can make the first transmission gear 21 rotate along the first axis direction, it is within the protection scope of the present invention.

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

[0044] like Figure 3 As shown, the rotating bracket 23 is rotatably arranged on the mounting base 22, and the rotating bracket 23 rotates around the second axis relative to the mounting base 22. In this embodiment, since the mounting base 22 and the rotating base 10 cannot rotate relative to each other, the rotating bracket 23 is also equivalent to rotating around the second axis relative to the rotating base 10. The rotating bracket 23 is used to install the antenna assembly 30; the second transmission gear 24 is drivingly connected to the rotating bracket 23, and the second transmission gear 24 is used to engage with the first transmission gear 21 to drive the antenna assembly 30 to rotate around the second axis.

[0045] Specifically, if Figure 3 As shown, 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, the two support columns 222 are provided with mounting holes 223, and the rotating bracket 23 is rotatably arranged between the two support columns 222.

[0046] The rotating bracket 23 includes: a transmission shaft 231, a connecting arm 232 and a mounting plate 233. The two ends of the transmission shaft 231 are respectively located in the mounting hole 223, and a bearing is fixedly connected in the mounting hole 223. The transmission shaft 231 forms a rotating connection structure with the support column 222 through the bearing, and the axis of the transmission shaft 231 is arranged along the second axis. Therefore, the transmission shaft 231 can rotate around the second axis relative to the rotating base 10. There are two connecting arms 232, and the first ends of the two connecting arms 232 are fixedly connected to the transmission shaft 231, and the second ends of the two connecting arms 232 are fixedly connected to the mounting plate 233 for mounting the antenna assembly 30. The second transmission gear 24 is fixedly connected to the transmission shaft 231, and the transmission shaft 231 is driven to rotate by the second transmission gear 24. The rotating transmission shaft 231 drives the connecting arm 232 and the mounting plate 233 to rotate between the two support columns 222, thereby realizing that the antenna assembly 30 rotates around the second axis relative to the rotating base 10.

[0047] In such Figure 4In another embodiment of the present invention shown, the driving gear 42, the first transmission gear 21, and the second transmission gear 24 are all bevel gears. The driving gear 42 rotates around the first axis, and the rotation axis direction of the first transmission gear 21 is the same as the first axis direction, and the rotation axis of the second transmission gear 24 is the second axis, the first axis is perpendicular to the second axis, and the change of the transmission direction is achieved by the cooperation 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, and 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 driving mechanism 40, the first limit portion 411 on the driving shaft 41 is disengaged from the limit engagement with the second limit portion 111 on the rotating base 10. At the same time, the driving gear 42 is engaged with the first transmission gear 21. The driving gear 42 drives the first transmission gear 21 to rotate. The first transmission gear 21 rotating around its own axis is engaged with the second transmission gear 24. Since it is a bevel gear, the direction of rotation is changed from the first axis direction to the second axis direction. The second transmission gear 24 rotating around the second axis direction drives the rotating bracket 23 to rotate, so that the antenna assembly 30 rotates around the second axis relative to the rotating base 10.

[0051] It can be seen from this that the antenna adjustment device of 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, and 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 omitted, fewer structural components are used, and the cost is reduced. In addition, due to the reduction of structural components, the overall structure is simpler.

[0052] It should be noted that if Figure 1 and Figure 2In the illustrated embodiment, there are two mounting seats 22, rotating brackets 23 and second transmission gears 24, and correspondingly, there are two second axes, namely the first sub-axis and the second sub-axis, and both the first sub-axis and the second sub-axis are perpendicular to the direction of the first axis.

[0053] A rotating bracket 23 and a second transmission gear 24 are provided on each mounting seat 22, wherein one rotating bracket 23 rotates around a first sub-axis relative to the mounting seat 22 on which it is located, and the other rotating bracket 23 rotates around a second sub-axis relative to the mounting seat 22 on which it is located, that is, one rotating bracket 23 rotates around the first sub-axis relative to the rotating base 10, and the other rotating bracket 23 rotates around the second sub-axis relative to the rotating base 10, and the two mounting seats 22 are distributed at 90° on the outer periphery of the rotating base 10, that is, the first sub-axis and the second sub-axis are perpendicular to each other.

[0054] With this arrangement, an antenna assembly 30 can be arranged 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 the present embodiment, there are two mounting seats 22, rotating brackets 23 and second transmission gears 24, but this is not restrictive. In some other embodiments not shown in the figure, there may be only one mounting seat 22, rotating bracket 23 and second transmission gear 24, or more than two. That is to say, as long as a plurality of mounting seats 22 are spaced apart and distributed on the 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 axes, they are all within the protection scope of the present invention.

[0056] exist Figure 4 In another embodiment shown, the mounting seat 22 is movable relative to the rotating base 10 in the direction of the second axis, and the mounting seat 22 causes the first transmission gear 21 to engage or disengage with 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 matched.

[0057] In this manner, 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 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, if Figure 4 As shown, the antenna adjustment device also includes: a first sliding part 51 and a second sliding part 52. In the present 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 are slidably matched in the direction of the second axis, and the slide groove and the slide rail are 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 part 51 is a slide rail, and the second sliding part 52 is a slide groove. However, this is not restrictive. In some other embodiments not shown in the figure, the first sliding part 51 can also be a slide groove, and the second sliding part 52 can be a slide rail. In other words, as long as the second sliding part 52 can slide with the first sliding part 51 in the direction of the second axis and can be limited in the rotation direction of the rotating base 10, it is within the protection scope of the present invention.

[0061] like Figure 4 As shown, the antenna adjustment device also includes: a first driving component 70, the first driving component 70 is respectively connected to the rotating base 10 and the mounting base 22, and the first driving component 70 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; the second magnet 72 is disposed on the mounting base 22, and the position of the first magnet 71 corresponds to the position of the second magnet 72.

[0063] It can be understood that the first magnet 71 and the second magnet 72 are electromagnets, and the first drive assembly 70 can be in an attractive state and a repulsive state by controlling the direction of the current. Specifically, the electromagnet includes an iron core and an electromagnetic coil wound on the iron core. By controlling the direction of the current on the electromagnetic coil, the magnetic poles generated at both ends of the iron core can be reversed. When in 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, so that the first magnet 71 and the second magnet 72 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, so that the first magnet 71 and the second magnet 72 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 component 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 are engaged; in the repulsive state, the first magnet 71 and the second magnet 72 repel each other, so that the first driving component 70 drives the mounting seat 22 and the rotating base 10 to move away from each other, so that the first transmission gear 21 and the second transmission gear 24 are separated.

[0065] The antenna adjustment device of the present invention can change the position of the mounting seat 22 relative to the rotating base 10 by setting the first driving component 70, thereby controlling whether the first transmission gear 21 is meshed with the second transmission gear 24, thereby controlling the rotation and stop of the antenna component 30. In combination with multiple mounting seats 22 and antenna components 30, the antenna components 30 in two different directions can be controlled to rotate independently, so that the antenna components 30 in the corresponding directions can stop in time when adjusted to the optimal position without interfering with each other. Compared with the prior art, the first driving component 70 of the present invention has a simpler structure, lower cost and lighter weight.

[0066] In such Figure 5 In another embodiment of the present invention, an antenna device is disclosed, including: a housing 80 , a supporting mechanism 60 , an antenna assembly 30 , the above-mentioned antenna adjustment device and a second driving assembly 90 .

[0067] A supporting structure is provided inside the shell 80, and the rotating base 10 is rotatably provided on the supporting structure inside the shell 80; the second driving assembly 90 is provided inside 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.

[0068] The support mechanism 60 is fixedly connected in the shell 80, and the rotating base 10 is rotatably arranged on the support mechanism 60; the second driving assembly 90 is arranged 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, if Figure 5 As shown, 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 sleeved on the outer wall of the support sleeve 61, and the support ring 62 is fixedly connected to the rotating base 10. In this embodiment, the axis of the support sleeve 61 is the first axis, the support sleeve 61 is fixedly connected with a bearing, and the support ring 62 is fixedly connected to the bearing, so as to achieve relative rotation of the support sleeve 61. By fixing the rotating base 10 with the support ring 62, the rotating base 10 can be supported while achieving rotation of the rotating base 10 along the first axis in the housing 80.

[0070] In such Figure 6 In the embodiment shown, the second driving assembly 90 includes: a third magnet 91 and a fourth magnet 92. The third magnet 91 is fixedly connected to the driving motor 43; the fourth magnet 92 is fixedly connected to the rotating base 10, and the position of the third magnet 91 corresponds to the position of the fourth magnet 92.

[0071] It can be understood that the third magnet 91 and the fourth magnet 92 are electromagnets, and the second drive component 90 can be made to have an attractive state and a repulsive state by controlling the direction of the current. Specifically, the electromagnet includes an iron core and an electromagnetic coil wound on the iron core. By controlling the direction of the current on the electromagnetic coil, the magnetic poles generated at both ends of the iron core can be reversed.

[0072] When in use, the third magnet 91 and the fourth magnet 92 are arranged opposite to each other, so that the first end of the iron core of the third magnet 91 is opposite to the first end of the iron core of the fourth magnet 92. In the attractive state, the magnetic poles generated by 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 are opposite, so that the third magnet 91 and the fourth magnet 92 attract each other; in the repulsive state, the magnetic poles generated by 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 are the same, so that the third magnet 91 and the fourth magnet 92 repel each other.

[0073] In the attractive state, the second driving assembly 90 drives the driving mechanism 40 to move to the first position, 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.

[0074] In the repulsive state, the second driving assembly 90 drives the driving mechanism 40 to move to the second position, the driving gear 42 is driven to cooperate with the transmission mechanism 20, and the driving shaft 41 is disengaged from the rotating base 10, so that the driving 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 component 90 is more uniform and more stable, in the present 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 is 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 are engaged for the next adjustment.

[0078] like Figure 7 and Figure 8 As shown, the present invention also discloses a control method for the above 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 following steps are also included:

[0085] S23: After the antenna assembly 30 rotates along the first axis by a preset angle, acquiring 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] Further, step S24 specifically includes the following steps:

[0088] S241: When the signal strength is greater than the preset signal strength, control 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, the driving mechanism 40 is controlled 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 then the process returns to step S23.

[0091] The control method of the antenna device of 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 whole machine and the complexity of the mechanism; on the other hand, due to the single-motor drive, the system analysis and calculation time is reduced, and the power consumption of the whole machine is also reduced.

[0092] It should be noted that, in step S23, there are 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, and 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 means that the position of the antenna assembly 30 is at a relatively good signal receiving position at this time, so the drive mechanism 40 does not need to move to the second position, but maintains the current position. Then, when the signal strength changes or the position of the antenna assembly 30 needs to be readjusted after the device is restarted, 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, but the drive mechanism 40 can be directly controlled to directly drive the antenna assembly 30 to rotate around 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, and 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 preset angle, the driving mechanism 40 is controlled to move to the second position and drive the antenna assembly 30 to rotate along the second axis, and at the same time, the signal strength of the antenna assembly 30 is obtained in real time, and then the next step is determined according to the signal strength. That is to say, the difference between this embodiment and the previous embodiment is that in this embodiment, the antenna assembly 30 rotates around the second axis and obtains the signal strength at the same time.

[0097] Therefore, in this embodiment, when the signal strength is greater than the preset signal strength, the driving mechanism 40 needs to stop driving the antenna assembly 30 to rotate around the second axis so that the antenna assembly 30 maintains the current position. Then, when the signal strength changes or the position of the antenna assembly 30 needs to be readjusted after the device is restarted, since the driving mechanism 40 is in the second position, when executing step S22 of this embodiment, it is necessary to control the driving mechanism 40 to move to the first position so as 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, and the driving mechanism 40 stops rotating or returns to step S23 after the antenna assembly 30 rotates around the second axis once.
