Abstract
Description
Technical Field
[0001] This invention belongs to the field of mobile communication technology, and specifically relates to a phase shift adjustment component and a frequency selective phase shifting device configured with the phase shift adjustment component. Background Technology
[0002] As a key component for rapidly optimizing antenna coverage networks, the antenna drive mechanism's core function is to precisely control components such as phase shifters to achieve phase adjustment. Currently, the industry commonly uses traditional mechanical structures such as screw mechanisms or rack and pinion gears to adjust the phase of the phase shifter. These mechanisms convert rotational motion into linear displacement through the rotation of the screw or the meshing of the rack and pinion gears, thereby driving the phase shifter to the designated position and completing the phase adjustment.
[0003] However, as communication technologies place increasingly stringent demands on antenna performance, existing technologies have gradually revealed significant shortcomings. Specifically, when the required adjustment range of the phase shifter is small, the machining accuracy of the screw or rack often becomes a key factor limiting system performance. If the stroke requirement exceeds the mechanical accuracy limit of the screw lead or rack pitch, existing technologies typically improve resolution by further reducing the screw lead or rack pitch. However, this improvement leads to a complete reconfiguration of the transmission output mechanism, including but not limited to adjusting the clearance between the screw and nut, thus significantly increasing design complexity and manufacturing costs.
[0004] Furthermore, excessive refinement of the screw lead or rack pitch directly leads to a decrease in transmission efficiency. For the same displacement requirement, a smaller lead or pitch means the screw needs to rotate more times or the gear needs to engage more teeth, causing the phase shifter's adjustment time to increase exponentially. This adjustment delay is particularly critical in dynamic coverage optimization scenarios. For example, in antenna beam tracking applications in mobile communication base stations, excessively long adjustment times will cause the beam pointing to lag behind the user's movement trajectory, leading to signal interruption or quality degradation, ultimately severely impacting the user experience.
[0005] Therefore, whether by reconstructing the transmission mechanism to meet accuracy requirements or by compromising user experience due to low adjustment efficiency, existing technical solutions inevitably lead to differentiated designs for the transmission output mechanism. This differentiation is not only reflected in the adjustment of mechanical structure parameters, but also extends to multiple levels such as control algorithms, drive circuits, and maintenance processes. Ultimately, this results in extended product development cycles, increased maintenance costs, and reduced system compatibility, becoming a bottleneck restricting the technological development of antenna transmission mechanisms. Summary of the Invention
[0006] The primary objective of this invention is to solve one of the aforementioned problems by providing a phase-shifting adjustment component and a frequency-selective phase-shifting device.

[0011] In one embodiment, the output component is a rack, which meshes with the output gear.
[0012] In one embodiment, the output component includes an output nut and an output screw, the output screw and the output screw forming a screw mechanism, and the output gear is sleeved on the outer periphery of the output nut.
[0013] In one embodiment, the input gear and the output gear mesh directly, or the input gear and the output gear mesh with the same gear, or the input gear and the output gear are connected by a gear train.
[0014] In one embodiment, the reduction mechanism includes a first double gear, which includes an intermediate gear and an input gear. The intermediate gear is fixed to the input gear and coaxially arranged, and the output gear meshes with the intermediate gear.
[0015] In one embodiment, the reduction mechanism includes a second double gear and a third double gear. The second double gear includes a first bevel gear and the input gear. The first bevel gear is fixed on the input gear and coaxially arranged. The third double gear includes a second bevel gear and a transition gear. The second bevel gear is fixed on the transition gear and coaxially arranged. The first bevel gear meshes with the second bevel gear, and the transition gear meshes with the output gear.
[0016] In one embodiment, the input component and the output component are arranged parallel to each other, the deceleration mechanism is disposed between the input component and the output component, and one end of the output component is used to connect to the phase shifting component.
[0017] In one embodiment, the phase-shifting adjustment assembly further includes a housing, the deceleration mechanism is installed inside the housing, and both the input component and the output component pass through the housing.
[0018] To achieve one of the objectives of this invention, a frequency-selective phase-shifting device is provided, comprising a frequency selection module, a phase-shifting module, and a plurality of phase-shifting adjustment components as described in any one of the preceding objectives. The plurality of phase-shifting adjustment components are respectively applied to and connected to a plurality of phase-shifting elements. The plurality of phase-shifting adjustment components are arranged in one row or two rows along the same axis. The frequency selection module is used to select one of the phase-shifting adjustment components, and the phase-shifting module is used to drive the input element of the selected phase-shifting adjustment component to move linearly, so as to correspondingly drive the connected phase-shifting element to move, thereby implementing phase shifting.
[0019] Compared with existing technologies, the present invention has many advantages, including but not limited to: The phase-shifting adjustment component of this invention comprises a reduction mechanism consisting of at least two meshing gears. This gear reduction mechanism has a transmission ratio characteristic, enabling precise scaling of the speed generated by the external torque received by the input component. For example, in applications requiring extremely high phase-shifting accuracy, such as phase shifters in high-precision communication equipment, by appropriately setting the number of teeth and transmission ratio of the gears, the relatively fast speed of the input component, which is difficult to control directly, can be reduced to a speed suitable for the phase shifter's movement according to a preset ratio. The processed speed signal is then accurately output to the output component, ensuring the precision of the phase-shifting operation.
[0020] In traditional phase-shifting methods, the required stroke of the phase shifter and the output stroke of the external transmission mechanism are often tightly coupled, making it difficult to adjust flexibly according to actual needs. However, the phase-shifting adjustment component of this invention successfully decouples the required stroke of the phase shifter from the output stroke of the external transmission mechanism by introducing a reduction gear mechanism. The external transmission mechanism can provide torque and stroke according to its conventional output characteristics, while the reduction gear mechanism in the phase-shifting adjustment component converts and adjusts the input stroke according to the specific requirements of the phase shifter, enabling the output component to provide a precisely matched stroke for the phase shifter's phase-shifting component. For example, when the external transmission mechanism can only provide a large stroke output due to design limitations, but the phase shifter actually requires a smaller and more precise stroke, the reduction gear mechanism can convert the large stroke into a smaller stroke by reducing speed and increasing torque, while ensuring the accuracy of the smaller stroke, thereby achieving a precise match between the two.
[0021] Because the phase-shifting adjustment component of this invention can achieve decoupling and precise matching of the travel, it possesses high flexibility and adaptability. Phase shifters in different application scenarios have diverse requirements for travel range and accuracy. For example, in some communication devices, the phase shifter may require a large travel range to meet signal coverage adjustment needs; while in other communication devices, the phase shifter requires a smaller but high-precision travel range to achieve fine signal adjustment. The phase-shifting adjustment component of this invention can flexibly and accurately adapt to the needs of phase shifters in various application scenarios by adjusting the number of teeth on the gears of the reduction mechanism to change the transmission ratio according to these different requirements. It can easily cope with changes in travel range or differences in accuracy requirements without requiring large-scale modifications to the external transmission mechanism or the phase shifter itself.

[0029] This invention provides a phase shift adjustment component, which can adjust the transmission accuracy through a deceleration mechanism, thereby adjusting the phase shift accuracy and optimizing the radiation performance of the antenna.
[0030] In a typical embodiment of the present invention, combined with Figure 1 and Figure 2 or Figure 3 and Figure 4 The phase-shifting adjustment assembly 100 includes an input component 110, an output component 120, and a reduction mechanism. The reduction mechanism is connected to both the input component 110 and the output component 120 via transmission.
[0031] Specifically, the output component 120 is configured to connect to the phase shifting component of the phase shifter, while the input component 110 is used to receive the external torque output by the external transmission mechanism. During operation, the input component 110 transmits the received torque to the output component 120 through the reduction mechanism, and the output component 120 then drives the phase shifting component to perform linear motion, thereby driving the phase shifter to perform phase shifting operation.
[0032] The reduction mechanism consists of at least two meshing gears. This reduction mechanism scales the speed output from the input device 110 proportionally and outputs the processed speed to the output device 120. In this way, decoupling matching between the required stroke of the phase shifter and the output stroke of the external transmission mechanism can be achieved. The phase shift adjustment component 100 has the ability to flexibly adapt to phase shifters with different stroke ranges and accuracy requirements, effectively overcoming a series of technical defects caused by stroke binding in traditional designs, such as increased mechanism size, limited adjustment accuracy, and prolonged response time.
[0033] The reduction mechanism includes at least an input gear 131 and an output gear 132. The input gear 131 is connected to the input component 110, and the output gear 132 is connected to the output component 120. There are three possible transmission methods: first, the input gear 131 and the output gear 132 are directly meshed; second, the input gear 131 and the output gear 132 are each meshed with the same gear; third, the input gear 131 and the output gear 132 are connected via a gear train.
[0034] The overall transmission ratio of the reduction mechanism can be adjusted by changing the gear ratio of any one or more pairs of meshing gears in the transmission path between the input gear 131 and the output gear 132. Specifically, when the input gear 131 and the output gear 132 are directly meshed, the transmission ratio of the reduction mechanism is directly determined by the gear ratio of the input gear 131 and the output gear 132; when the input gear 131 and the output gear 132 are connected through a gear or gear train, the transmission ratio of the reduction mechanism is determined by the combined effect of the gear ratios of each pair of meshing gears.
[0035] Based on the above principle, the transmission ratio of the reduction mechanism can be flexibly set or changed by setting the number of teeth on the gear or replacing it with gears with different numbers of teeth. This allows for precise control of the stroke and speed of the output component 120, enabling the phase shift adjustment assembly 100 to fully adapt to the diverse stroke and accuracy requirements of different phase shifters.
[0036] Under the operating conditions of the phase-shifting adjustment component 100, the output component 120 is connected to the input component 110 via the reduction mechanism. Specifically, when the input component 110 moves under the action of an external force, its kinetic energy is transmitted through the reduction mechanism and ultimately acts on the output component 120, thereby driving the output component 120 to move in the same or opposite direction as the input component 110.
[0037] The transmission ratio i set in the reduction mechanism is a core parameter that determines the output motion characteristics. This transmission ratio i directly affects the speed relationship between the input component 110 and the output component 120, specifically: the moving speed v of the output component 120 within the same time interval... 输出 The moving speed v of the input device 110 输入 There exists a definite proportional relationship between them, expressed mathematically as v 输出= v 输入 * i.
[0038] Based on the aforementioned speed ratio, furthermore, the linear displacement S generated by the output component 120 in any operating cycle... 输出 The linear displacement stroke S provided by the input element 110 输入 A corresponding functional relationship, determined by the same transmission ratio i, is established between them. This relationship can be summarized by the following stroke formula: S 输出 = S 输入 * i Among them, transmission ratio The value is designed and set through the gear ratio of the meshing gears inside the reduction mechanism. When When the output stroke is proportionally amplified relative to the input stroke, it is suitable for achieving a wide range of rapid adjustments to the phase shifter; when At this time, the output stroke is reduced proportionally, which is suitable for realizing high-precision micro-adjustment of the phase shifter.
[0039] Therefore, by adjusting the transmission ratio i of the reduction mechanism, the final displacement stroke of the output component 120 can be flexibly and accurately controlled without changing the external drive input conditions. This effectively decouples the rigid relationship between the output capability of the drive mechanism and the stroke requirement of the phase shifter, providing a unified and configurable transmission solution for phase adjustment of the antenna system in different application scenarios.
[0040] In a typical embodiment of the present invention, the input component 110 is in the form of a rack and pinion mechanism, a screw mechanism, or a drive shaft, and the output component 120 is also in the form of a rack and pinion mechanism. The input component 110 and the output component 120 can be combined to form a variety of different combination schemes, and the specific combination schemes are described in detail in the following embodiments.
[0041] In the first embodiment of the present invention, combined with Figure 1 and Figure 2 The input component 110 is configured as a rack (referred to as input rack 111 for ease of description), and the output component 120 is also configured as a rack (referred to as output rack 121). The input rack 111 meshes with the input gear 131, and the output rack 121 meshes with the output gear 132. Regarding the transmission connection between the input gear 131 and the output gear 132, there are three possibilities: first, the input gear 131 and the output gear 132 mesh directly with each other; second, the input gear 131 and the output gear 132 each mesh with the same gear; third, the input gear 131 and the output gear 132 are connected through a gear train.
[0042] In the first embodiment of the present invention, the embodiment is illustrated by taking the reduction mechanism as including a double gear (for ease of subsequent description, the double gear is referred to as the first double gear 133), but this example should not be regarded as a limitation on the scope of the embodiment.
[0043] The first double gear 133 consists of an intermediate gear 134 and an input gear 131, wherein the intermediate gear 134 is fixedly mounted on the input gear 131, and the two are coaxially arranged. The output gear 132 meshes with the intermediate gear 134, and the input rack 111, input gear 131, intermediate gear 134, output gear 132, and output rack 121 form a transmission link. When an external torque is applied, the external torque is transmitted sequentially through the input rack 111 to the output rack 121, and then the output rack 121 drives the phase shifter's phase shifting component to move, thereby realizing the phase shifting operation.
[0044] In this embodiment, the number of teeth of the input gear 131 and the intermediate gear 134 of the first double gear 133 are set to different values. When the input rack 111 moves one tooth pitch, it drives the input gear 131 to rotate by the angle corresponding to one tooth. Since the intermediate gear 134 has a different number of teeth than the input gear 131, when this rotational motion is output through the intermediate gear 134, the intermediate gear 134 will obtain a different rotation angle than the input gear 131. This different rotation angle will ultimately be converted into different linear displacements between the output rack 121 and the input rack 111. The proportional relationship of this linear displacement, i.e., the transmission ratio, is directly determined by the tooth ratio between the input gear 131 and the intermediate gear 134 of the first double gear 133.
[0045] The transmission ratio of the reduction mechanism depends on the tooth count relationship of each meshing gear in the transmission chain between the input gear 131 and the output gear 132. Specifically, in a transmission path including an intermediate gear 134, the transmission ratio is... The ratio of the number of teeth on the input gear 131 to the number of teeth on the intermediate gear 134 is determined by i=Z. 输入 / Z 中间 The Z 输入 Z represents the number of teeth on input gear 131. 中间 This represents the number of teeth on the intermediate gear 134. Furthermore, the transmission ratio can be changed by altering the number of teeth on the intermediate gear 134 or the input gear 131. For example, when the number of teeth on the input gear 131 is... The number of teeth on the intermediate gear 134 is At that time, transmission ratio If the intermediate gear 134 is replaced with a gear with a number of teeth... The gear ratio then becomes accordingly. Therefore, the transmission ratio can be flexibly adjusted by selecting gears with different numbers of teeth, thereby achieving precise and adjustable control of the output stroke.
[0046] In the phase-shifting adjustment assembly 100, the output rack 121 moves in the same direction as the input rack 111. However, because the input gear 131 and the intermediate gear 134 of the first double gear 133 have different numbers of teeth (i.e., a tooth ratio not equal to 1), the linear motion of the input rack 111, after being speed-changed by the double gear, drives the output rack 121 to move at different speeds. Therefore, under the same input conditions, the displacement S of the output rack 121 is different. 输出 The displacement stroke S of the input rack 111 输入 There is a defined scaling relationship between them, specifically satisfying: S 输出 = S输入 * i in, The transmission ratio between the input gear 131 and the intermediate gear 134 of the first double gear 133 is determined by the gear ratio of the double gear and its associated transmission gear. The transmission ratio can be changed by selecting a first double gear 133 with different tooth number combinations. This allows for continuous or step-wise adjustment of the output stroke.
[0047] Therefore, this embodiment can use a first double gear 133 with a different gear ratio as the core speed change element, so that the transmission ratio of the entire reduction mechanism can be changed conveniently and economically by replacing only this single component. This realizes the modularity and configurability of the phase shift adjustment component 100, effectively solving the problem that the entire transmission mechanism must be redesigned or a long screw / rack must be replaced to adapt to different phase shifter strokes. This significantly improves the versatility of the product and reduces research and development and production costs.
[0048] In the second embodiment of the present invention, combined with Figure 3 and Figure 4 The input component 110 is an input rack 111, and the output component 120 is a screw mechanism. The input rack 111 meshes with the input gear 131, and the output component 120 establishes a transmission connection with the output gear 132. There are three possible transmission connection methods between the input gear 131 and the output gear 132: first, the input gear 131 and the output gear 132 mesh directly with each other; second, the input gear 131 and the output gear 132 each mesh with the same gear 134; third, the input gear 131 and the output gear 132 are connected through a gear train.
[0049] Specifically, the output component 120 is a screw mechanism, which includes a nut (referred to as output nut 122 for ease of description) and a screw (referred to as output screw 123). The output screw 123 is inserted into the output nut 122, and one end of the output screw 123 is used to connect with the phase shifting component of the phase shifter. The output gear 132 is sleeved on the output nut 122. When the output gear 132 receives the torque output from the input rack 111 through the transmission path, it can drive the output nut 122 to rotate. During the rotation of the output nut 122, it will correspondingly drive the output screw 123 to perform linear motion, and then the output screw 123 will drive the phase shifting component of the phase shifter to move linearly, thereby realizing the phase shifting operation.
[0050] In a second embodiment of the present invention, the embodiment is described using an example of the reduction mechanism comprising two double gears, but this example should not be considered as a limitation on the scope of this embodiment. The two double gears are a second double gear 135 and a third double gear 137.
[0051] The second double gear 135 is composed of the input gear 131 and a bevel gear (referred to as the first bevel gear 136 for ease of description). The first bevel gear 136 is fixedly mounted on the input gear 131, and the two are coaxially arranged. The third double gear 137 is composed of a transition gear 138 and a bevel gear (referred to as the second bevel gear 139). The second bevel gear 139 is fixedly mounted on the transition gear 138, and the two are also coaxially arranged.
[0052] The input gear 131 meshes with the input rack 111, the first bevel gear 136 meshes with the second bevel gear 139, and the adapter gear 138 meshes with the output gear 132. Through these meshing relationships, a transmission chain is formed from the input rack 111 to the output gear 132. Based on this transmission chain, the input rack 111 can output the transmission torque to the output nut 122 via the reduction mechanism. After receiving the transmission torque, the output nut 122 drives the output screw 123 to move linearly, which in turn drives the phase shifter's phase shifting component to move, thus realizing the phase shifting operation.
[0053] In the transmission chain, the meshing of the input gear 131 and the input rack 111 constitutes the first-stage gear ratio. The meshing of the first bevel gear 136 and the second bevel gear 139 constitutes the second-stage gear ratio. The meshing of the adapter gear 138 and the output gear 132 forms a third-stage gear ratio. The total transmission ratio i of the reduction mechanism 总 The number of teeth is determined by the ratio of each gear, i. 总 = i1* i2* i3.
[0054] When the input rack 111 moves at a speed v 输入 During linear movement, the motion is transmitted to the output gear 132 via the transmission chain, and the speed of the output gear 132 is v. 输出= v 输入 * i 总 Therefore, the total transmission ratio i 总 It directly determines the conversion ratio from input linear motion to output rotational motion.
[0055] The output gear 132 drives the output nut 122 to rotate. The output nut 122 and the output screw 123 form a helical pair with a lead of [missing information]. The linear displacement stroke S of the output screw 123 输出 Displacement S of input rack 111 输入 The relationship between them is: S 输出 = S 输入 * P / i 总 This formula shows that by adjusting the total transmission ratio i 总 This allows control over the displacement of the output screw 123, thereby precisely adjusting the phase change of the phase shifter. Based on the aforementioned transmission relationship, this embodiment achieves flexible scaling and precision adjustment of the phase shift stroke through modular gear tooth design and combination: increasing i 总 More precise phase adjustment can be achieved with small input strokes; reducing i 总 This allows for a wider range of phase coverage within a limited input stroke.
[0056] In the third embodiment of the present invention, the input component 110 is in the form of a screw mechanism, and the output component 120 is in the form of an output rack 121. The input component 110 is connected to the input gear 131, and the output rack 121 meshes with the output gear 132. There are three possible transmission connection methods between the input gear 131 and the output gear 132: first, the input gear 131 and the output gear 132 mesh directly with each other; second, the input gear 131 and the output gear 132 each mesh with the same gear 134; third, the input gear 131 and the output gear 132 are connected through a gear train.
[0057] Specifically, in this embodiment, the input component 110 is a screw mechanism, which includes a nut (referred to as the input nut for ease of description, not shown) and a screw (referred to as the input screw, not shown). The input screw is inserted into the input nut, and the input gear 131 is sleeved on the outer circumference of the input nut. The input screw is used to receive an externally applied rotational torque, which drives the input nut to rotate, and the input nut does not move linearly along the axial direction of the input screw. Since the input gear 131 is sleeved on the input nut, the rotation of the input nut will drive the input gear 131 to rotate synchronously. The input gear 131 then drives the output gear 132, which is connected to it, to rotate. The output gear 132 then drives the output rack 121 to move linearly, and finally the output rack 121 drives the phase shifter to move, realizing the phase shifting operation.
[0058] Regarding the specific transmission ratio of the reduction mechanism, please refer to the relevant content in the first and second embodiments above. To save space, it will not be repeated here.
[0059] In the fourth embodiment of the present invention, the input component 110 adopts the form of a screw mechanism, and the output component 120 also adopts the form of a screw mechanism. The input component 110 establishes a transmission connection with the input gear 131, and the output component 120 meshes with the output gear 132. Regarding the transmission connection between the input gear 131 and the output gear 132, there are three scenarios: first, the input gear 131 and the output gear 132 directly mesh with each other; second, the input gear 131 and the output gear 132 each mesh with the same gear 134; third, the input gear 131 and the output gear 132 are connected through a gear train.
[0060] Specifically, the input screw mechanism in this embodiment includes an input nut and an input screw, the input screw being inserted into the input nut, and the input gear 131 being sleeved on the outer periphery of the input nut. The output screw 123 mechanism includes an output nut 122 and an output screw 123, the output screw 123 being inserted into the output nut 122, and the output gear 132 being sleeved on the outer periphery of the output nut 122.
[0061] During operation, the input screw receives an externally applied rotational torque, which drives the input nut to rotate, but the input nut does not move linearly along the axial direction of the input screw. Since the input gear 131 is fitted onto the input nut, the rotation of the input nut causes the input gear 131 to rotate synchronously. The input gear 131 then drives the output gear 132, which is connected to it, to rotate. The output gear 132 drives the output nut 122 to rotate, and the output nut 122 then drives the output screw 123 to move linearly. Finally, the output screw 123 moves the phase shifter's phase shifting component, thus achieving the phase shifting operation.
[0062] Regarding the specific transmission ratio of the reduction mechanism, please refer to the relevant content in the first and second embodiments above. To save space, it will not be repeated here.
[0063] In the fifth embodiment of the present invention, the input component 110 is in the form of a drive shaft (not shown). The drive shaft is inserted into the gear hole of the input gear 131, and when the drive shaft receives an externally applied torque, it can drive the input gear 131 to rotate synchronously.
[0064] The output component 120 is either a rack and pinion mechanism or a screw mechanism, and the output gear 132 is connected to the output component 120 in a transmission relationship. During operation, the input gear 131 drives the output gear 132 to move, the output gear 132 further drives the output component 120 to move, and finally the output component 120 drives the phase shifting component connected to it to move, thereby realizing the phase shifting operation.
[0065] Regarding the transmission connection between the input gear 131 and the output gear 132, there are three scenarios: First, the input gear 131 and the output gear 132 directly mesh with each other; second, the input gear 131 and the output gear 132 each mesh with the same gear; third, the input gear 131 and the output gear 132 are connected through a gear train.
[0066] Regarding the specific transmission ratio of the reduction mechanism, please refer to the relevant content in the first and second embodiments above. To save space, it will not be repeated here.
[0067] In a typical embodiment of the present invention, the input component 110 and the output component 120 are arranged in parallel, and the deceleration mechanism is disposed in the space between the input component 110 and the output component 120.
[0068] The phase-shifting adjustment assembly 100 further includes a housing 140, combined with... Figure 1 or Figure 3 The deceleration mechanism is installed and fixed inside the housing 140. The housing 140 has a limiting function, which can effectively constrain the deceleration mechanism installed inside it, prevent the deceleration mechanism from leaving the preset position during operation, and ensure the stability and reliability of the entire phase shift adjustment assembly 100.
[0069] Both the input component 110 and the output component 120 are disposed through the housing 140, so that the input component 110 can easily receive torque input from the outside, and the output component 120 can smoothly drive the phase shifting component to move, thereby realizing the function of phase shifting adjustment.
[0070] The present invention also provides a frequency-selective phase-shifting device (not shown), which includes a frequency selection module, a phase-shifting module, and a plurality of phase-shifting adjustment components 100 as described above. The plurality of phase-shifting adjustment components 100 are respectively connected to a plurality of phase-shifting elements one by one. The phase-shifting adjustment components 100 drive the connected phase-shifting elements to move, so that the phase shifter to which the phase-shifting element is located performs a phase-shifting operation.
[0071] The plurality of phase-shifting adjustment components 100 are arranged sequentially along a first axis, wherein the first axis is perpendicular to the longitudinal axis of the output component 120 in the phase-shifting adjustment component 100. Specifically, the plurality of phase-shifting adjustment components 100 may be arranged in one row; or, the plurality of phase-shifting adjustment components 100 may be arranged in two rows, and the two rows of phase-shifting adjustment components 100 are arranged in an alternating vertical layout.
[0072] The frequency selection module can select a target phase shift adjustment component 100 from one or two rows of phase shift adjustment components 100. After selecting the target phase shift adjustment component 100, the phase shift module establishes a transmission connection with the input gear 131 input component 110 of the target phase shift adjustment component 100, drives the input component 110 to move, and sequentially drives the reduction mechanism and output component 120 of the target phase shift adjustment component 100 to move. Finally, the output component 120 drives the phase shift component connected to it to move, thereby realizing the phase shift function.
[0073] In summary, the phase-shifting adjustment component of this invention uses a reduction mechanism to precisely scale the speed output from the input component, and then outputs the processed speed signal to the output component. Through this process, the required stroke of the phase shifter and the output stroke of the external transmission mechanism are successfully decoupled and precisely matched. This endows the phase-shifting adjustment component of this invention with high flexibility and adaptability, enabling it to be flexibly and accurately adapted to the diverse requirements of the phase shifter's stroke range and accuracy in different application scenarios, thereby significantly improving the versatility and practicality of the phase-shifting adjustment component.
