Abstract
Description
Technical Field
[0001] This application belongs to the field of communication equipment technology, specifically relating to an antenna azimuth adjustment device and an antenna. Background Technology
[0002] With the increasing number of mobile communication standards and frequency bands, site resources are becoming increasingly difficult to acquire. In the case of site sharing, in order to avoid visual pollution caused by installing too many antennas with different frequency bands on the top of the base station tower, and at the same time to reduce the load on the base station tower, multi-band antennas can effectively solve the above problems and have become the future development trend of smart antennas.
[0003] To adjust the azimuth angle of each frequency band in a multi-band antenna, most antennas use azimuth adjustment devices to achieve this adjustment. Because these devices have many components, the antenna becomes quite large. This not only affects the overall layout inside the radome but also makes the antenna bulky.
[0004] Based on the above problems, it is particularly important to propose a multi-azimuth adjustment device that can adjust the azimuth of each frequency band and has a small size. Summary of the Invention
[0005] The purpose of this application is to provide an antenna azimuth adjustment device and antenna, which can at least solve the problem of the large size of current azimuth adjustment devices.
[0006] To solve the above-mentioned technical problems, this application is implemented as follows:
[0007] This application provides an antenna azimuth angle adjustment device, which includes: an adjustment mechanism and a shifting mechanism;
[0008] The adjustment mechanism includes a first driving component, a transmission component, and multiple adjustment components. The first driving component is connected to the transmission component in a driving manner. Each adjustment component includes a rotating component and a moving component. The rotating component is sleeved on the outside of the moving component and is threadedly connected to the moving component.
[0009] The shifting mechanism is connected to the transmission component, and the shifting mechanism is switched through the transmission component to be connected to the rotating component of at least one of the plurality of adjustment components.
[0010] This application also provides an antenna, including the antenna azimuth adjustment device described above.
[0011] In this embodiment, the first driving component can transmit power and motion to the adjusting component via a transmission component, thereby driving the adjusting component to move. The shifting mechanism is connected to the transmission component, allowing it to switch to a transmission connection with the rotating component of at least one of the multiple adjusting components. This allows the power and motion output by the first driving component to be transmitted to the rotating component of at least one adjusting component, switching between a transmission connection state and a transmission disconnect state. Furthermore, the rotating component of each adjusting mechanism is threadedly connected to the moving component. As the rotating component rotates, it drives the moving component to move, facilitating the adjustment of the antenna azimuth angle according to actual operating conditions. Based on the above configuration, the rotating component in this embodiment can be configured according to the movement of the moving component, and the rotating component does not need to be long at the rear of the moving component, thus reducing the space occupied by the rotating component at the rear and providing space for other components. This reduces the overall size of the adjusting device in the moving component's direction, alleviating to some extent the problem of the large and bulky size of the entire antenna.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0032] refer to Figures 1 to 6 This application discloses an antenna azimuth angle adjustment device for adjusting the antenna azimuth angle. The antenna can be a multi-frequency antenna with multiple different frequency bands, and the azimuth angle of each frequency band can be adjusted using the adjustment device described in this application. The disclosed adjustment device includes an adjustment mechanism 100 and a shifting mechanism 200.
[0033] The adjustment mechanism 100 is the power component of the antenna azimuth adjustment device. In some embodiments, the adjustment mechanism 100 may include a first driving component 110, a transmission component 120, and multiple adjustment components 130. The first driving component 110 is the power supply component, and the transmission component 120 is the power transmission component. The first driving component 110 and the transmission component 120 are connected in a transmission manner. Thus, the power output by the first driving component 110 can be transmitted to the transmission component 120 and then transmitted backward through the transmission component 120. In addition, the multiple adjustment components 130 are used to adjust the azimuth angle, so that the azimuth angle of multiple frequency bands in the multi-frequency antenna can be adjusted by using multiple adjustment components 130 in one set of adjustment device.
[0034] Each adjusting component 130 may include a rotating component 131 and a moving component 132. The rotating component 131 can rotate about its own axis, and the moving component 132 can move along its own axis. It should be noted that the rotation axis of the rotating component 131 may be parallel to the movement axis of the moving component 132. In a more specific embodiment, the two axes may also be collinear.
[0035] The rotating component 131 is sleeved on the outside of the movable component 132 and is threadedly connected to the movable component 132. The rotating component 131 may have an internal thread, and correspondingly, the movable component 132 may have an external thread. The threaded connection between the rotating component 131 and the movable component 132 is achieved through the engagement of the internal and external threads. Therefore, when the rotating component 131 rotates, it can drive the movable component 132 to move, such as extending or retracting, to facilitate adjustment of the azimuth angle of the corresponding frequency band.
[0036] For example, the rotating part 131 can be in the form of a nut, a threaded sleeve, etc., and the moving part 132 can be in the form of a screw, a stud, etc. Of course, the threaded connection between the rotating part 131 and the moving part 132 can also be in other forms, as long as the threaded connection can be achieved, and the specific form is not limited.
[0037] The shifting mechanism 200 is the switching part of the adjustment device. It is connected to the transmission component 120 to drive at least a portion of the transmission component 120 to move, thereby enabling switching between different azimuth adjustment states for different frequency bands. In this embodiment, the shifting mechanism 200 can be switched via the transmission component 120 to be connected to the rotating component 131 of at least one of the multiple adjustment components 130. Thus, under the action of the shifting mechanism 200, the transmission component 120 can transmit the power output from the first driving component 110 to the rotating component 131 of at least one of the multiple adjustment components 130, causing the rotating component 131 of at least one adjustment component 130 to rotate. This rotating component 131 then drives the corresponding moving component 132 to move, thereby adjusting the azimuth angle of the corresponding frequency band to meet the adjustment requirements under specific operating conditions.
[0038] For example, the shifting mechanism 200 can switch the transmission component 120 to be connected to the rotating part 131 of one of the adjustment components 130, thereby enabling adjustment of the azimuth angle of the corresponding frequency band of the adjustment component 130. Alternatively, the shifting mechanism 200 can switch the transmission component 120 to be connected to the rotating parts 131 of two adjustment components 130 respectively, thereby enabling simultaneous adjustment of the azimuth angles of two frequency bands corresponding to the two adjustment components 130. In addition to the above methods, the shifting mechanism 200 can also switch the transmission component 120 to be connected to the rotating parts 131 of other numbers of adjustment components 130 to meet the needs of adjusting the azimuth angle of different frequency bands under different operating conditions.
[0039] In this embodiment, the rotating component 131 is sleeved on the outside of the moving component 132, and the rotation of the rotating component 131 can drive the moving component 132 to move. Furthermore, the rotating component 131 can be set according to the movement of the moving component 132, so that the rotating component 131 does not need to be long at the rear in the movement direction of the moving component 132, thereby reducing the space occupied by the rotating component 131 at the rear, so as to provide accommodation space for other components. In other words, compared with the method of moving the kit and rotating the rod, this embodiment does not need to set a long rod in advance, but sets the length of the moving component 132 and the rotating component 131 according to the actual adjustment requirements, thereby reducing the space occupied by the moving component 132 and the rotating component 131 at the rear in the movement direction. Therefore, this embodiment can reduce the overall size of the adjustment device in the movement direction of the moving component 132, which can effectively alleviate the problem of the large and heavy size of the entire antenna. In addition, compared with the gear and rack drive, the drive method using the threaded engagement of the rotating part 131 and the moving part 132 can have mechanical gain, that is, the ratio of load to driving force is higher and the transmission smoothness is higher.
[0040] refer to Figure 1 In some embodiments, the adjustment device may further include a frame 400, which provides a mounting base for mechanisms such as the adjustment mechanism 100 and the shifting mechanism 200. Multiple adjustment components 130 may be arranged along a first direction on the frame 400. Exemplarily, the extending directions of the moving parts 132 of the multiple adjustment components 130 may be parallel, so that the moving parts 132 of each of the multiple adjustment components 130 can move in the same or opposite directions. The first direction is perpendicular to the moving direction of the moving parts 132, such as... Figure 2 As shown, the movable component 132 can move in the vertical direction, while the first direction can be the left and right direction.
[0041] The rotating component 131 of each adjusting component 130 can be rotatably connected to the frame 400. This arrangement ensures both smooth rotation of each rotating component 131 and prevents it from moving, thus providing support for the movement of the moving component 132. For example, at one end of the movement direction, the frame 400 can have multiple mounting holes arranged along the first direction. The rotating components 131 of each adjusting component 130 can be mounted in the corresponding mounting hole, and the moving component 132 can pass through the corresponding mounting hole to avoid the frame 400 interfering with the movement of the moving component 132.
[0042] The transmission component 120 may include a transmission shaft 121 and a first driving wheel 122 and at least one first driven wheel 123 respectively drivenly connected to the transmission shaft 121. Each first driven wheel 123 is slidably connected to the transmission shaft 121, and the transmission shaft 121 extends along a first direction and is rotatably connected to the frame 400. With this arrangement, the first driving wheel 122 and at least one first driven wheel 123 can rotate synchronously with the transmission shaft 121. At this time, when power is input from the first driving wheel 122, the power can be transmitted to at least one first driven wheel 123 through the transmission shaft 121, thereby causing at least one first driven wheel 123 to rotate. At the same time, the position of each first driven wheel 123 on the transmission shaft 121 can be changed, thereby switching the transmission connection state of each first driven wheel 123 with different adjustment components 130, thereby realizing the adjustment of the azimuth angle of different frequency bands.
[0043] For example, the cross-section of the drive shaft 121 can be polygonal, such as triangle, quadrilateral, hexagon, etc., as long as it can transmit rotational power, and the specific form is not limited.
[0044] In order to enable the drive shaft 121 to rotate relative to the frame 400, at least one end of the drive shaft 121 may be provided with a cylindrical surface. In this case, the cylindrical surfaces at both ends of the drive shaft 121 can be rotatably connected to the frame 400 to ensure the smooth rotation of the drive shaft 121.
[0045] The first driving component 110 may include a driving wheel 111, which is connected to the first driving wheel 122 for transmission. The driving wheel 111 transmits the power and motion output by the first driving component 110 to the first driving wheel 122, causing the first driving wheel 122 to rotate. The first driving wheel 122 drives the transmission shaft 121 to rotate, and the transmission shaft 121 drives at least one first driven wheel 123 to rotate synchronously. This allows the power and motion to be transmitted to the rotating component 131 of the corresponding adjustment component 130 through the first driven wheel 123. Finally, the rotation of the rotating component 131 drives the corresponding moving component 132 to move, thereby achieving the adjustment of the azimuth angle of the corresponding frequency band.
[0046] In order to switch the azimuth adjustment process of different frequency bands, the shift mechanism 200 can drive at least one first driven wheel 123 to slide along the transmission shaft 121, so as to switch the position of at least one first driven wheel 123, thereby enabling at least one first driven wheel 123 to be connected to the azimuth adjustment component 130 of different frequency bands, thereby realizing the adjustment of azimuth angle of different frequency bands to meet the adjustment requirements of frequency band azimuth angle under actual working conditions.
[0047] In order to transmit the power and motion of the first driven wheel 123 to the rotating part 131 of the adjusting component 130 so as to drive the rotating part 131 to rotate, the transmission component 120 may also include multiple pairs of second driving wheels 124 and second driven wheels 125 that are connected to each other in a transmission manner, and the multiple pairs of second driving wheels 124 and second driven wheels 125 correspond one-to-one with multiple adjusting components 130 so as to transmit the power and motion to the corresponding multiple adjusting components 130 respectively.
[0048] The second driving wheel 124 is rotatably connected to the frame 400 and is either connected to or disconnected from the first driven wheel 123. The second driven wheel 125 is fixedly connected to the rotating component 131. With this configuration, when the first driven wheel 123 is connected to the second driving wheel 124, the first driven wheel 123 can drive the second driving wheel 124 to rotate, the second driving wheel 124 drives the second driven wheel 125 to rotate, and finally the second driven wheel 125 drives the rotating component 131 to rotate. When the first driven wheel 123 is disconnected from the second driving wheel 124, power and motion cannot be transmitted to the second driving wheel 124. At this time, the corresponding rotating component 131 cannot rotate, and therefore the azimuth angle of the corresponding frequency band cannot be adjusted.
[0049] For example, the second driven wheel 125 can be a kit, the rotating member 131 can be a cylinder, and the moving member 132 can be a rod. In this case, the second driven wheel 125 can be sleeved on the outside of the rotating member 131, and the moving member 132 can be inserted through the inside of the rotating member 131, so that both transmission can be performed and the movement of the moving member 132 can be guaranteed to be uninterrupted.
[0050] The second driven wheel 125 and the rotating component 131 can be fixedly connected, for example, by welding or bonding. Of course, the second driven wheel 125 and the rotating component 131 can also be integrally formed. Regardless of the method used, the overall strength of the second driven wheel 125 and the rotating component 131 can be guaranteed.
[0051] refer to Figure 3 In some embodiments, the first driven wheel 123 may include a first spur tooth 1231, and the second driving wheel 124 may include a second spur tooth 1241. The second spur tooth 1241 meshes with the first spur tooth 1231, thereby transmitting the power and motion of the first driven wheel 123 to the second driving wheel 124. Of course, other transmission connection methods can also be used between the first driven wheel 123 and the second driving wheel 124, such as helical gear transmission, etc., which are not specifically limited here.
[0052] The second driving wheel 124 may also include a first bevel tooth 1242 coaxially arranged with the second straight tooth 1241, and the second driven wheel 125 may include a second bevel tooth 1251 that meshes with the first bevel tooth 1242. In this way, the power and motion of the second driving wheel 124 can also be transmitted to the second driven wheel 125.
[0053] refer to Figure 4 In other embodiments, the first driven wheel 123 may include a third spur tooth portion 1232, and the second driving wheel 124 may include a fourth spur tooth portion 1243, which meshes with the third spur tooth portion 1232. This allows the power and motion of the first driven wheel 123 to be transmitted to the second driving wheel 124. Of course, other transmission connection methods can also be used between the first driven wheel 123 and the second driving wheel 124, such as helical gear transmission, etc., which are not specifically limited here.
[0054] The second driving gear 124 may also include a worm gear portion 1244 coaxially arranged with the fourth spur gear portion 1243, and the second driven gear 125 may include a worm wheel portion 1252, which meshes with the worm gear portion 1244. In this way, the power and motion of the second driving gear 124 can also be transmitted to the second driven gear 125.
[0055] Based on the above method, in this embodiment of the application, the power and motion output by the first driving component 110 can be smoothly and efficiently transmitted to the first driving wheel 122 through the driving wheel 111, and then smoothly transmitted to the first driven wheel 123 through the first driving wheel 122. The power and motion can be smoothly and efficiently transmitted to the corresponding second driving wheel 124 through the first driven wheel 123, and then smoothly and efficiently transmitted to the second driven wheel 125 through the second driving wheel 124. Finally, the second driven wheel 125 drives the corresponding rotating component 131 to rotate, and the rotating component 131 drives the corresponding moving component 132 to move, so as to adjust the azimuth angle of the corresponding frequency band through the movement of the moving component 132.
[0056] refer to Figure 1 , Figure 2 and Figure 5 To achieve the switching of the position of the first driven wheel 123, the shifting mechanism 200 may include a bracket 210, and the frame 400 may include a guide shaft 410 extending along a first direction, and the bracket 210 is slidably connected to the guide shaft 410, so that the bracket 210 can move relative to the frame 400 along the guide shaft 410 in the first direction.
[0057] Furthermore, the bracket 210 can contact or separate from at least one first driven wheel 123. When the bracket 210 contacts at least one first driven wheel 123, as the bracket 210 moves, it can drive at least one first driven wheel 123 to move synchronously in the first direction, thereby adjusting the position of at least one first driven wheel 123 relative to a plurality of second driving wheels 124, and thus switching the transmission connection state between at least one first driven wheel 123 and at least one of a plurality of second driving wheels 124 to meet the adjustment requirements of azimuth angles in different frequency bands.
[0058] refer to Figure 2 In order to drive the support 210 to move, the shifting mechanism 200 may also include a second driving component 220. The second driving component 220 can drive the support 210 to move along the guide shaft 410, so that the support 210 can drive at least one first driven wheel 123 to move, and the first driven wheel 123 can be connected to different second driving wheels 124 for transmission.
[0059] The second drive component 220 may include a shift gear 221 and a rack 222. The shift gear 221 meshes with the rack 222. The rack 222 is disposed on the bracket 210 and extends along the first direction. The rotation of the shift gear 221 can drive the rack 222 to move along the first direction, and the rack 222 can drive the bracket 210 to move synchronously along the first direction. This allows the bracket 210 to contact or separate from at least one first driven wheel 123. Furthermore, the shifting method achieved by the cooperation of the shift gear 221 and the rack 222 can improve shifting efficiency and shifting reliability.
[0060] The second drive component 220 may further include a second motor 223 and a second rotating shaft 224. The motor shaft of the second motor 223 is connected to one end of the second rotating shaft 224, and the shift gear 221 is connected to the other end of the second rotating shaft 224. Thus, under the driving action of the second motor 223, the motor shaft drives the second rotating shaft 224 to rotate, and the second rotating shaft 224 drives the shift gear 221 to rotate synchronously. Therefore, the meshing shift gear 221 and rack 222 can drive the bracket 210 to move back and forth in the first direction.
[0061] In addition, the second rotating shaft 224 extends along the moving direction and is rotatably connected to the frame 400. The frame 400 can support the second rotating shaft 224 and ensure that the second rotating shaft 224 can rotate smoothly. It can also ensure the rigidity of the second rotating shaft 224 so that the shift gear 221 located at the other end of the second rotating shaft 224 can smoothly transmit power with the rack 222.
[0062] In some embodiments, the rack 222 is offset from the rotating member 131 in the direction of movement. For example, the rack 222 may be located behind the rotating member 131 in the direction of movement. Based on this arrangement, since the rack 222 is arranged along the first direction and offset from the rotating member 131, when setting the rack 222, it is not necessary to place it above the rotating member 131; instead, the rack 222 can be placed behind the rotating member 131. This effectively reduces the overall thickness of the adjusting device and effectively utilizes the space behind the rotating member 131, thereby reducing the volume of the adjusting device. It should be noted that the direction of the thickness of the adjusting device is perpendicular to both the first direction and the direction of movement, as shown below. Figure 2 As shown, the direction of the thickness is the vertical direction.
[0063] refer to Figure 5In some embodiments, the bracket 210 may include a first cantilever 211 and a second cantilever 212 extending along the moving direction, and a connecting arm 213 connecting the first cantilever 211 and the second cantilever 212. The first cantilever 211 is provided with a first fork 2111 at one end away from the connecting arm 213, and the second cantilever 212 is provided with a second fork 2121 at one end away from the connecting arm 213. The first fork 2111 contains one of the first driven wheels 123, and the second fork 2121 contains the other first driven wheel 123. A rack 222 is provided on the connecting arm 213.
[0064] Based on the above configuration, under the action of the second drive component 220, the rack 222 can act on the connecting arm 213, and the connecting arm 213 drives the first cantilever 211 and the second cantilever 212 to move synchronously in the first direction. Thus, the first shift fork 2111 can be used to move the transmission shaft 121 of one of the first driven wheels 123 to switch the transmission connection state between one of the first driven wheels 123 and the second drive wheel 124 corresponding to different adjustment components 130. Furthermore, the second shift fork 2121 can be used to move the transmission shaft 121 of the other first driven wheel 123 to switch the transmission connection state between the other first driven wheel 123 and the second drive wheel 124 corresponding to different adjustment components 130.
[0065] In this embodiment, the two first driven wheels 123 can be simultaneously connected to the second driving wheels 124 corresponding to two of the multiple adjustment components 130, thereby enabling the simultaneous adjustment of the two adjustment components 130 and allowing switching to adjust the azimuth angle of the two frequency bands, thus improving the adjustment efficiency.
[0066] In other embodiments, the bracket 210 may also include other numbers of cantilever arms, each cantilever arm corresponding to a first driven wheel 123, so as to simultaneously adjust other numbers of adjustment components 130, thereby allowing switching to adjust the azimuth angle of other numbers of frequency bands to meet the adjustment requirements under actual working conditions.
[0067] refer to Figure 2To achieve drive, the first drive component 110 may include a first motor 112 and a first rotating shaft 113. The first rotating shaft 113 extends along the movement direction and is rotatably connected to the frame 400. The motor shaft of the first motor 112 is connected to a transmission rod at one end of the first rotating shaft 113, and the drive wheel 111 is drivenly connected to the other end of the first rotating shaft 113. Based on this, under the driving action of the first motor 112, the motor shaft drives the first rotating shaft 113 to rotate, and the first rotating shaft 113 drives the drive wheel 111 to rotate synchronously. Thus, the drive wheel 111 can drive the first driving wheel 122 to rotate, and finally the first driving wheel 122 drives the first driven wheel 123 to rotate through the transmission shaft 121. In addition, the frame 400 can also support the first rotating shaft 113, ensuring that the first rotating shaft 113 can rotate smoothly and ensuring the rigidity of the first rotating shaft 113 so that the driving force at the other end of the first rotating shaft 113 can be smoothly transmitted to the first driving wheel 122.
[0068] Considering that the first rotating shaft 113 extends along the direction of movement, the axis of the drive wheel 111 also extends along the direction of movement. The first driving wheel 122 can be sleeved on the outside of the transmission shaft 121, which extends along the first direction. Thus, the axis of the drive wheel 111 is perpendicular to the axis of the first driving wheel 122. Based on this, both the drive wheel 111 and the first driving wheel 122 can be bevel gears, and they mesh with each other, thereby achieving both a change in the axis and ensuring smooth transmission. Of course, other methods can also be used for transmission between the drive wheel 111 and the first driving wheel 122, such as worm gears, etc., without specific limitations.
[0069] Continue to refer to Figure 2 To ensure the movement accuracy of the movable component 132, the frame 400 may include multiple first guide rods 420 corresponding one-to-one with the multiple adjustment components 130. The multiple first guide rods 420 are arranged along a first direction, each extending along the movement direction, and the end of the movable component 132 adjacent to the first drive component 110 is slidably connected to the corresponding first guide rod 420. With this arrangement, under the guidance of the first guide rods 420, the movable component 132 can move precisely along the movement direction, thereby preventing tilting or offset during movement, ensuring the movement accuracy of the movable component 132, and consequently ensuring the reliability of adjusting the azimuth angle at various frequencies.
[0070] In addition, in the direction of movement, the first guide rod 420 can be positioned at a rearward position on the frame 400 to guide the rear end of the moving part 132.
[0071] In other embodiments, the frame 400 may include a plurality of second guide rods (not shown in the figure) corresponding one-to-one with the plurality of adjustment components 130. The plurality of second guide rods are arranged along a first direction, each second guide rod extends along the moving direction, and the end of the moving component 132 away from the first driving component 110 is slidably connected to the corresponding second guide rod. With this arrangement, under the guidance of the second guide rods, the moving component 132 can be moved precisely along the moving direction, thereby preventing the moving component 132 from tilting or deviating during the movement, ensuring the moving accuracy of the moving component 132, and thus ensuring the reliability of adjusting the azimuth angle of each frequency.
[0072] In addition, in the direction of movement, the second guide rod can be positioned at the front of the frame 400 to guide the front end of the moving part 132.
[0073] In other embodiments, a first guide rod 420 and a second guide rod may be provided simultaneously to guide the rear end and front end of the moving member 132 at the same time, thereby further improving the moving accuracy of the moving member 132.
[0074] In this embodiment, the adjustment device may further include multiple phase shifters (not shown in the figure), with each phase shifter corresponding to a moving element 132 of the multiple adjustment components 130. Based on this, the movement of each moving element 132 can drive the corresponding phase shifter to move synchronously, thereby achieving the adjustment of the corresponding phase shifter and thus the adjustment of the azimuth angle of the corresponding frequency band. It should be noted that the specific structure and working principle of the phase shifter can be found in related technologies and will not be described in detail here.
[0075] In addition, the adjustment device may also include a controller 500, which can control the adjustment mechanism 100 and the shifting mechanism 200 respectively, so that multiple phase shifters can be adjusted under the action of the controller 500. Compared with the method of each phase shifter corresponding to a separate controller 500, the number of controllers 500 can be reduced, thereby reducing the size of the adjustment device and, consequently, the size of the base station antenna. It should be noted that the specific structure and working principle of the controller 500 can be found in relevant technologies and will not be described in detail here.
[0076] In the moving direction of the moving member 132, the controller 500 can be located in the area of the rotating member 131 adjacent to the first driving member 110. In this way, the space at the rear of the rotating member 131 can be effectively utilized, and the size of the adjustment device in the moving direction can be reduced to a certain extent, which is beneficial to reducing the volume of the adjustment device.
[0077] Considering that the shifting mechanism 200 can switch the movement states of different adjustment components 130, when at least one adjustment component 130 moves, the phase shifter corresponding to the at least one adjustment component 130 moves to adjust the azimuth angle of the corresponding frequency band. However, the remaining adjustment components 130 remain stationary. In this case, to ensure that the phase shifter corresponding to the remaining adjustment components 130 moves and causes a change in the azimuth angle of the corresponding frequency band, the adjustment device in this embodiment may further include multiple locking mechanisms 300, such as... Figure 1 and Figure 3 As shown, multiple locking mechanisms 300 are arranged one-to-one with multiple adjusting components 130. In this way, each locking mechanism 300 can lock or unlock the corresponding adjusting component 130 to ensure that the adjusting component 130 is not interfered with when working and will not move unexpectedly when not working.
[0078] To reduce the number of components and size of the adjustment device, the locking mechanism 300 can be switched simultaneously during gear shifting via the shifting mechanism 200. In some embodiments, as the shifting mechanism 200 shifts gears, when the first driven wheel 123 and the second driving wheel 124 are connected, the locking mechanism 300 corresponding to the second driving wheel 124 releases its lock, allowing the second driving wheel 124 to rotate. This rotates the corresponding adjustment component 130, thereby adjusting the azimuth angle of the corresponding frequency band. Conversely, when the first driven wheel 123 and the second driving wheel 124 are disconnected, the locking mechanism 300 corresponding to the disconnected second driving wheel 124 locks it to prevent accidental rotation. This ensures that the corresponding adjustment component 130 does not move unexpectedly, thus preventing accidental changes in the azimuth angle of the corresponding frequency band.
[0079] Among them, such as Figure 1 , Figure 2 and Figure 6 As shown, the locking mechanism 300 may include a locking clamp 310. One end of the locking clamp 310 is connected to the frame 400, and the other end is freely disposed. The locking clamp 310 surrounds at least a portion of the outer side of the second drive wheel 124 and can be released or separated from the outer edge of the second drive wheel 124. It should be noted that when the free end of the locking clamp 310 is subjected to a force, it can move away from the outer edge of the second drive wheel 124, thereby releasing the locking clamp 310 from the second drive wheel 124 and releasing its locking effect. In this case, the second drive wheel 124 can be smoothly rotated by the first driven wheel 123 to drive the corresponding adjustment component 130 and realize the adjustment of the azimuth angle of the corresponding frequency band.
[0080] Of course, when the force on the free end of the locking clamp 310 disappears or is subjected to a reverse force, the free end of the locking clamp 310 can approach the outer edge of the second driving wheel 124, thereby allowing the locking clamp 310 to hug the outer edge of the second driving wheel 124 and achieve a locking effect. In this case, the transmission between the first driven wheel 123 and the second driving wheel 124 is disconnected, causing the second driving wheel 124 to lose power. At the same time, the locking clamp 310 hugs the outer edge of the second driving wheel 124, thereby ensuring that the second driving wheel 124 will not rotate unexpectedly, and thus achieving a locking effect on the corresponding adjustment component 130, effectively preventing unexpected changes in the azimuth angle of the corresponding frequency band.
[0081] In some embodiments, the locking clamp 310 can be an elastic locking clamp. The surface of the elastic locking clamp facing the second drive wheel 124 may be provided with a snap-fit protrusion 311 or a snap-fit arc surface. The snap-fit protrusion 311 or the snap-fit arc surface can engage or lock with the outer edge of the second drive wheel 124 to ensure that the second drive wheel 124 does not rotate accidentally. For example, the elastic locking clamp can be a plastic component, but other methods are also possible, which are not specifically limited here.
[0082] To unlock the locking clamp 310, the first cantilever 211 and the second cantilever 212 each have a boss structure 2112 at the end away from the connecting arm 213. The free end of the locking clamp 310 has a pushing protrusion 312 for abutting and cooperating with the boss structure 2112. Thus, when the shifting mechanism 200 drives the first driven wheel 123 to move to a transmission connection with the second driving wheel 124, the boss structure 2112 can abut against the pushing protrusion 312 of the locking clamp 310 corresponding to the transmission-connected second driving wheel 124, so that the locking clamp 310 separates from the outer edge of the second driving wheel 124, thereby releasing the locking effect of the locking clamp 310 on the second driving wheel 124. At this time, the first driven wheel 123 can drive the second driving wheel 124 to rotate smoothly, so as to realize the movement of the corresponding adjustment component 130, and then the azimuth angle of the corresponding frequency band can be adjusted.
[0083] When the shifting mechanism 200 drives the first driven wheel 123 to disengage from the second driving wheel 124, the boss structure 2112 disengages from the pushing protrusion 312, so that the free end of the locking clamp 310 is no longer subjected to force. At this time, the locking clamp 310 can return to its original position and continue to hold the outer edge of the second driving wheel 124, preventing the second driving wheel 124 from rotating unexpectedly and changing the azimuth angle of the corresponding frequency band.
[0084] In order to facilitate the sliding of the boss structure 2112 into the push protrusion 312, in some embodiments, the push protrusion 312 is provided with an inclined guide surface 3121 on at least one side along the first direction. In this way, the inclined guide surface 3121 can guide the boss structure 2112 so that the boss structure 2112 can slide smoothly into the push protrusion 312, thereby preventing jamming.
[0085] In this embodiment, after the controller 500 receives the angle adjustment signal, the second motor 223 rotates, which drives the shift gear 221 to rotate through the second rotating shaft 224. The shift gear 221 drives the rack 222 to move along the first direction, thereby driving the first driven wheel 123 to move along the first direction through the bracket 210, so that the first driven wheel 123 meshes with the corresponding second driving wheel 124 to complete the shift.
[0086] After the gear shift is completed, the first motor 112 rotates, which drives the drive wheel 111 to rotate via the first rotating shaft 113. The drive wheel 111 drives the first driving wheel 122 to rotate. The first driving wheel 122 drives the first driven wheel 123 to rotate via the transmission shaft 121. The first driven wheel 123 drives the second driving wheel 124, which meshes with it, to rotate. The second driving wheel 124 drives the second driven wheel 125 to rotate. The second driven wheel 125 drives the rotating component 131 to rotate. The rotating component 131 drives the moving component 132 to move. The moving component 132 drives the slider of the phase shifter to move, thereby changing the phase shifter circuit network and thus realizing the beam azimuth angle adjustment of the frequency band.
