Description

Technical Field

[0002] With the rapid development of mobile communication technology, the performance and functionality of base station antennas are constantly being optimized to meet growing communication demands. Conventional technologies often employ complex phase adjustment devices to achieve multi-band signal transmission and beam adjustment within base station antennas. These devices utilize gear transmission, motor drive, and other methods to adjust the antenna phase, thereby achieving azimuth adjustment of the beam.

[0003] However, the existing phase adjustment device has a complex structure, including multiple components, resulting in a larger antenna size, which is detrimental to the compact layout and aesthetics of the base station antenna. Furthermore, the complex structure increases the number of failure points of the device, reduces reliability, and increases maintenance costs. Summary of the Invention

[0056] See also Figure 1 , an embodiment of the present application provides an antenna phase adjustment device 100, which is used to drive the phase shifter slider of the antenna device to perform phase adjustment to accurately control the direction of the antenna beam. The antenna device is, for example, a base station antenna. In addition, in the case where the antenna device includes multiple phase shifters, each phase shifter is responsible for adjusting the signal of a specific frequency band. In this case, the antenna phase adjustment device 100 provided by the embodiment of the present application is used to achieve multi-band beam direction adjustment by independently controlling the slider position of these phase shifters. In a specific embodiment, the phase shifter is generally composed of a main printed circuit board and a movable slider printed circuit board. A transmission line trace is provided on the main printed circuit board, and the slider printed circuit board can be moved on the main printed circuit board. By changing the position of the slider printed circuit board, the transmission path length of the radio frequency signal is changed, thereby changing the phase of the signal.

[0057] The antenna phase adjustment device 100 provided in an embodiment of the present application includes at least two drive shafts 10 and a shift module, which includes a moving structure 21 and a rotating structure 20. The at least two drive shafts 10 are configured to connect to phase shifter blades in at least two different frequency bands in a one-to-one correspondence. All drive shafts 10 together constitute a drive module B, which drives the phase shifter blades in all frequency bands. The drive module B and the rotating structure 20 together form a multi-frequency phase module C that implements beam direction adjustment in multiple frequency bands.

[0058] The movable structure 21 is in transmission engagement with at least two drive shafts 10, and is used to selectively drive the phase shifter vanes corresponding to any one of the drive shafts 10 for phase adjustment. The rotating structure 20 is rotationally connected to the movable structure 21 and is configured to rotate through different transmission positions, driving the movable structure 21 in transmission engagement with one of the at least two drive shafts 10 at each transmission position. It will be readily understood that a transmission position refers to the position of the movable structure 20 after rotating through a predetermined angle. Each transmission position corresponds to a drive shaft 10. In one transmission position, the movable structure 21 is in transmission engagement with the drive shaft 10 corresponding to that transmission position, while the drive shafts 10 corresponding to the other transmission positions are disengaged from the movable structure 21. By rotating the movable structure 20 between different transmission positions, the movable structure 21 can switch between different transmission positions. Driven by the movable structure 21, the drive shaft 10 in transmission engagement with it drives the corresponding phase shifter vanes for phase adjustment. The remaining drive shafts 10 not in transmission engagement with the moving structure 21 remain stationary, causing the phase shifters corresponding to these drive shafts 10 to also remain stationary. This allows for shifting (i.e., switching between adjusting the phases of signals in different frequency bands). In practical applications, the rotating structure 20 can be rotated to the corresponding transmission position based on the desired frequency band. Then, driven by the moving structure 21, the drive shafts 10 in transmission engagement with it drive the corresponding phase shifters to adjust the phase.

[0059] In practical applications, the number of drive shafts 10 can be adjusted according to the frequency band requirements of the antenna device. For example, for an antenna device that needs to adjust 8 frequency bands, 8 drive shafts 10 can be set, each drive shaft 10 corresponding to a phase shifter slider of a frequency band.

[0060] The antenna phase adjustment device 100 provided in an embodiment of the present application switches between different transmission positions by rotating the rotating structure 20, causing the movable structure 21 to switch between transmission engagements with different drive shafts 10, ultimately achieving a gear shift operation (i.e., switching between adjusting the signal phases of different frequency bands). This shift module has a simpler structure, and the shifting operation is more precise and reliable. Furthermore, by rotatably connecting the rotating structure 20 and the movable structure 21, the two can be moved as a whole, thereby enabling the driving force to be applied directly to the entire structure, thereby simplifying the structure and improving the device's integration. Furthermore, this integrated design reduces the number of transmission components, and the compact structure allows the device to better adapt to limited installation space. This design advantage is particularly evident in space-sensitive applications such as base station antennas. Furthermore, the integrated design reduces manufacturing costs and assembly difficulty, while also reducing the device's failure rate and improving maintenance convenience.

[0061] In some embodiments, the rotating structure 20 includes a shifting component 22 and at least two rotating components 23, and the shifting component 22 and at least two rotating components 23 are all rotationally connected to the mobile structure 21, and each transmission position, each rotating component 23 and each drive shaft 10 corresponds one to one; the shifting component 22 is used to transmit and cooperate with the corresponding rotating component 23 at any transmission position to drive the rotating component 23 to rotate to a position in which it transmits and cooperates with the corresponding drive shaft 10; it is also used to drive the rotating component 23 to rotate away from the above-mentioned position in the process of leaving the transmission position, so that the rotating component 23 is released from the corresponding drive shaft 10, and the shifting component 22 is released from the corresponding rotating component 23 after leaving the transmission position.

[0062] Specifically, as the shift component 22 rotates and reaches any transmission position, it engages with the corresponding rotating component 23, driving the rotating component 23 to a position in which it engages with the corresponding drive shaft 10. As the shift component 22 continues to rotate in the same direction to leave the transmission position, it drives the rotating component 23 away from the transmission position with the corresponding drive shaft 10, effectively releasing the transmission engagement between the rotating component 23 and the corresponding drive shaft 10. Furthermore, the shift component 22 also releases the transmission engagement with the corresponding rotating component 23 while leaving the transmission position. Continuing to rotate in the same direction, the shift component 22 reaches the next transmission position, effectively switching between different transmission positions. The shift component 22 and each rotating component 23 are integrated into the mobile structure 21 and are all capable of rotating relative to the mobile structure 21. This allows the shift component 22 and each rotating component 23 to move as a single unit with the mobile structure 21, allowing the driving force to be applied directly to the entire unit rather than to separate transmission components. This simplifies the transmission structure and improves the integration of the device. Furthermore, this integrated design reduces the number of transmission components, and its compact structure allows the device to better adapt to limited installation spaces. This design advantage is particularly evident in space-critical applications such as base station antennas. Furthermore, the integrated design reduces manufacturing costs and assembly difficulty, while also lowering the device's failure rate and improving maintenance convenience.

[0063] Furthermore, in some embodiments, at least two drive shafts 10 are disposed around the rotation centerline A of the shift component 22 and are parallel to the rotation centerline A of the shift component 22. In one example, all the drive shafts 10 are evenly distributed around the rotation centerline A of the shift component 22. Figure 2Each drive shaft 10 includes, for example, a cylindrical shaft body 101, the axis of which is parallel to the rotational centerline A of the shift component 22. Each rotating component 23 is coaxially disposed with the corresponding drive shaft 10 and is rotatably disposed on the movable structure 21 about the axis of the corresponding drive shaft 10. By arranging at least two drive shafts 10 about the rotational centerline A of the shift component 22, the rotating components 23 can be compactly arranged around the shift component 22. Furthermore, by arranging each rotating component 23 coaxially with the corresponding drive shaft 10 and rotatably disposed on the movable structure 21 about the axis of the corresponding drive shaft 10, the space occupied by each rotating component 23 and each drive shaft 10 can be reduced, thereby improving the structural compactness of the device and better adapting to limited installation space.

[0064] See also Figures 2 to 6 , and combined with Figure 1 Each drive shaft 10 is provided with a first mating structure 102. The first mating structure 102 is, for example, a structure formed on the outer periphery of the shaft body 101. The shift component 22 is provided with a first transmission structure 221; each rotating component 23 is provided with a second mating structure 231 and a second transmission structure 232. The first transmission structure 221 is used to engage with the second transmission structure 232 of the rotating component 23 corresponding to any transmission position in transmission engagement, thereby driving the rotating component 23 to rotate from a non-mated position to a mated position in transmission engagement with the corresponding drive shaft 10. The second mating structure 231 of the rotating component 23 in the mated position engages with the first mating structure 102 of the corresponding drive shaft 10. The shift component 22 is also used to drive the rotating component 23 corresponding to the transmission position to rotate from the mated position to the non-mated position when leaving the transmission position, thereby disengaging the second mating structure 231 from the first mating structure 102. After the shift component 22 leaves the transmission position, the first transmission structure 221 disengages from the second transmission structure 232 of the corresponding rotating component 23.

[0065] Specifically, see Figure 7The shift component 22 is used to selectively rotate to any transmission position, and in the process of rotating to the transmission position, its first transmission structure 221 is transmitted and cooperated with the second transmission structure 232 of the rotating component 23 corresponding to the transmission position. Under the action of this cooperation, the rotating component 23 can be driven to rotate so that it rotates from the non-cooperating position to the engaging position, that is, when the shift component 22 is in the transmission position, the rotating component 23 corresponding to the transmission position is in the engaging position. In this engaging position, the second engaging structure 231 of the rotating component 23 is transmitted and cooperated with the first engaging structure 102 of the corresponding drive shaft 10. Under the action of this cooperation, the drive shaft 10 coaxial with the rotating component 23 can move together with the moving structure 21, that is, the drive shaft 10 can be driven by the moving structure 21 to move in a direction parallel to the rotation center line A of the shift component 22, thereby driving the phase shifter slider connected to the drive shaft 10 to move, thereby realizing the signal phase adjustment of the corresponding frequency band of the phase shifter slider.

[0066] As the shift component 22 continues to rotate in the same direction to leave the current transmission position, it drives the rotating component 23 corresponding to the transmission position to rotate from the above-mentioned mating position to the non-mating position. In the non-mating position, the second mating structure 231 of the rotating component 23 is disengaged from the first mating structure 102 of the corresponding drive shaft 10, so that the drive shaft 10 coaxial with the rotating component 23 does not move with the moving structure 21, that is, the drive shaft 10 remains stationary when the moving structure 21 moves in a direction parallel to the rotation center line A of the shift component 22, so that the position of the phase shifter slide connected to the drive shaft 10 remains unchanged.

[0067] Afterwards, as the shift component 22 continues to rotate in the same direction, the first transmission structure 221 and the corresponding second transmission structure 232 of the rotating component 23 are released from transmission engagement. At this time, the rotating component 23 remains in the non-engaged position and does not rotate with the shift component 22 .

[0068] In a specific embodiment, all the drive shafts 10 are evenly distributed around the rotation center line A of the shift component 22. In this case, the shift component 22 is rotated to each transmission position in sequence by rotating in the same direction and at the same angle, for example. Figure 4 and Figure 7As shown, the eight drive shafts 10 are evenly distributed around the rotational centerline A of the shift component 22. Correspondingly, the eight rotating components 23 are evenly distributed around the rotational centerline A of the shift component 22. That is, the central angle between the rotational centers of two adjacent rotating components 23 is 45°. In this case, the shift component 22 reaches a new transmission position every 45° rotation in the same direction. After each rotation of the shift component 22 through the same angle (i.e., the aforementioned central angle), its first transmission structure 221 engages with the second transmission structure 232 of one of the rotating components 23. As the shift component 22 rotates from its current transmission position to the next, the first transmission structure 221 disengages from the second transmission structure 232 of the rotating component 23 corresponding to the current transmission position. After the shift component 22 completes one rotation, the first transmission structure 221 has engaged and disengaged with the second transmission structures 232 of all rotating components 23. In practical applications, the shift component 22 can be rotated to the desired transmission position by setting the shift component 22 to a multiple (1 to N times) of the above-mentioned rotation angle (i.e., 360° divided by N, where N is the number of transmission positions, for example, 8).

[0069] It is easy to understand that when the shifting component 22 approaches any transmission position, it will drive the rotating component 23 corresponding to the transmission position to rotate, so that it rotates from the non-matching position to the matching position. Then, by making the shifting component 22 stay in the transmission position, the rotating component 23 corresponding to the transmission position can be kept in the matching position, for example Figure 4 The position of the rotating component 23 located on the far left side of the transmission mechanism allows the second mating structure 231 of the rotating component 23 to maintain a transmission mating state with the corresponding first mating structure 102 of the drive shaft 10. At this time, the drive shaft 10 can be moved in a direction parallel to the rotation centerline A of the shift component 22 under the drive structure 21. After completing the movement of the corresponding phase shifter slide, if it is necessary to switch to another frequency band, the shift component 22 is moved away from the current transmission position and rotated to another transmission position. In the process of leaving the current transmission position, the shift component 22 drives the rotating component 23 corresponding to the transmission position to rotate from the above-mentioned mating position to the non-mating position. In the non-mating position, the second mating structure 231 of the rotating component 23 is disengaged from the corresponding first mating structure 102 of the drive shaft 10, for example Figure 4All rotating components 23 except the leftmost one are in the non-coupling position. Subsequently, the first transmission structure 221 disengages the second transmission structure 232 of the rotating component 23 corresponding to the current transmission position. At this point, the rotating component 23 remains in the non-coupling position and no longer rotates with the shift component 22. This prevents the drive shaft 10, which is coaxial with the rotating component 23, from moving with the moving structure 21. Specifically, the drive shaft 10 remains stationary when the moving structure 21 moves in a direction parallel to the rotational centerline A of the shift component 22, thereby maintaining the position of the phase shifter blade connected to the drive shaft 10. This allows the signal phase of any frequency band to be freely adjusted according to specific needs by rotating the shift component 22 by a corresponding angle.

[0070] The antenna phase adjustment device 100 provided in this embodiment of the present application utilizes the rotation of the shift component 22 to switch between engagement and disengagement between its first transmission structure 221 and the second transmission structures 232 of each rotating component 23. This allows each rotating component 23 to switch between an engaged and disengaged position, thereby achieving a shift operation (i.e., switching between adjusting the signal phases of different frequency bands). Compared to existing technologies (such as those using gear transmission for shifting), this shifting structure is simpler, provides more precise and reliable shifting, and avoids the potential for jamming or wear issues associated with traditional gear transmissions.

[0071] In some embodiments, as Figure 6 As shown, the rotating component 23 is annular and is arranged around the coaxial drive shaft 10; the second matching structure 231 is at least one convex portion formed on the inner circumference of the rotating component 23, for example Figure 6 4 convex portions are shown, and the 4 convex portions can be evenly distributed along the circumference of the rotating component 23. Figure 8 As shown, the first engagement structure 102 is a recessed channel structure formed on the outer circumference of the drive shaft 10. This recessed channel structure is configured such that, when the rotating component 23 is in the engaged position, the recessed channel structure and the protrusions engage in a limited manner in a direction parallel to the rotational centerline A of the shift component 22 (i.e., in the direction of movement of the movable structure 21). Under this engagement, the rotating component 23 can drive the drive shaft 10 to move in a direction parallel to the rotational centerline A of the shift component 22 when the movable structure 21 moves. When the rotating component 23 is in the disengaged position, the recessed channel structure and the protrusions disengage, and the rotating component 23 moves independently of the movable structure 21, while the drive shaft 10 remains stationary.

[0072] By nesting the annular rotating component 23 with the drive shaft 10, the rotation component 23 and the drive shaft 10 are more closely matched, improving the stability and reliability of the device while also helping to reduce the size of the device. On this basis, through the cooperation of the protrusions and the recessed structure, the precise switching of the motion state of the drive shaft 10 can be achieved. It is easy to understand that the release of the recessed structure from the protrusions can refer to the release of the limited cooperation between the recessed structure and the protrusions in the direction parallel to the rotation centerline A of the shift component 22, while the protrusions can still be located in the recessed structure, or it can refer to the removal of the protrusions from the recessed structure to achieve the release of the cooperation with the recessed structure.

[0073] There are many types of concave channel structures to achieve the above functions. In some embodiments, please refer to Figure 8 The groove structure includes at least one first groove 102a extending in a direction parallel to the rotation center line A of the shift component 22 (i.e., the movement direction of the moving structure 21), and at least one second groove group, each first groove 102a and each second groove group are alternately arranged along the circumferential direction of the drive shaft 10; each second groove group includes a plurality of second grooves 102b spaced apart in a direction parallel to the rotation center line A of the shift component 22, and each second groove 102b extends along the circumferential direction of the drive shaft 10; the first groove 102a and the second groove group are alternately arranged along the circumferential direction of the drive shaft 10; The number of the two groove groups is the same as the number of the protrusions, and when the rotating component 23 is in the engaged position, each protrusion is located one-to-one in any second groove 102b in each second groove group, and is limitedly engaged with the side wall surface of the second groove 102b along a direction parallel to the rotation center line A of the shift component 22; the number of the first grooves 102a is the same as the number of the protrusions, and when the rotating component 23 is in the non-engaged position, each protrusion is located one-to-one in each first groove 102a.

[0074] Specifically, Figure 6 Taking the example of four protrusions shown, which are evenly distributed along the circumference of the rotating member 23, there are four first recessed channels 102a and four second recessed channel groups. The four first recessed channels 102a and the four second recessed channel groups are alternately arranged along the circumference of the drive shaft 10. That is, a second recessed channel group is provided between each two adjacent first recessed channels 102a. Each second recessed channel 102b in each second recessed channel group is connected to an adjacent first recessed channel 102a.

[0075] When the rotating part 23 is in the non-matching position, each protrusion is located in each first recess 102a correspondingly. Since the second recess 102b extends in a direction parallel to the rotation center line A of the shifting part 22, the protrusion located in the first recess 102a can move in the first recess 102a relative to the drive shaft 10 in a direction parallel to the rotation center line A of the shifting part 22, so that the limiting matching between the protrusion and the recess structure in the direction parallel to the rotation center line A of the shifting part 22 is released, and each protrusion can still be located in the recess structure (i.e., located in the first recess 102a).

[0076] When the rotating member 23 is in the engaged position, each protrusion is located in a one-to-one correspondence within any second recessed channel 102b in each second recessed channel group. Because the second recessed channel 102b extends along the circumference of the drive shaft 10, the sidewall surface 102b1 of the second recessed channel 102b can engage with the protrusion located within the second recessed channel 102b in a direction parallel to the rotational centerline A of the shifting member 22, thereby achieving a positional engagement between the protrusion and the recessed channel structure in a direction parallel to the rotational centerline A of the shifting member 22. Furthermore, by providing each second recessed channel group with a plurality of second recessed channels 102b spaced apart in a direction parallel to the rotational centerline A of the shifting member 22, the protrusions located within the first recessed channel 102a can be moved into the corresponding second recessed channel 102b when the rotating member 23 switches from the non-engaged position to the engaged position. It is easy to understand that the greater the distribution density of the second recessed channels 102b in each set of second recessed channels 102b in a direction parallel to the rotational centerline A of the shift member 22, the easier it is to ensure that the protrusion located in the first recessed channel 102a can be moved into the corresponding second recessed channel 102b at any position. Of course, the distribution density of the second recessed channels 102b should also be increased if the sidewalls of the second recessed channels 102b are sufficiently strong to cooperate with the protrusions in retaining the position.

[0077] The design of the first grooves 102a and the second groove group improves the matching accuracy between the drive shaft 10 and the rotating component 23. Moreover, the alternating arrangement of the first grooves 102a and the second groove group makes the motion state switching of the drive shaft 10 more flexible.

[0078] There are many ways to form the above-mentioned recess structure. In some embodiments, the outer peripheral surface of the drive shaft 10 is formed with multiple groups of protrusion groups, and the multiple groups of protrusion groups are arranged at intervals along the circumference of the drive shaft 10, and the intervals between two adjacent groups of protrusion groups constitute a first recess 102a; each group of protrusion groups includes multiple protrusions 102d arranged at intervals along a direction parallel to the rotation center line A of the shift component 22, and the intervals between each adjacent two protrusions 102d constitute a second recess 102b; the number of each protrusion 102d in different protrusion groups is the same, and the positions along the direction parallel to the rotation center line A of the shift component 22 correspond one to one.

[0079] Furthermore, in some embodiments, to ensure that the protrusions in the first recessed channel 102a can more smoothly move into the corresponding second recessed channel 102b, each protrusion 102d is formed with tapered portions 102d1 at both ends along the circumference of the drive shaft 10. The thickness of these tapered portions 102d1, parallel to the rotational centerline A of the shift component 22, decreases gradually from the center of the protrusion 102d toward its edge. These tapered portions 102d1 guide the protrusions, ensuring smooth movement into the corresponding second recessed channel 102b, thereby improving device reliability. Furthermore, the tapered portions 102d1 can guide the protrusions into the second recessed channel 102b even if their position is not perfectly aligned with the nearest second recessed channel 102b.

[0080] Furthermore, in some embodiments, to facilitate the installation of the rotating component 23 on the drive shaft 10, at least one mounting recess 102c is provided at one end of the drive shaft 10. One end of each mounting recess 102c is located on the end surface of the drive shaft 10 (away from the end connected to the phase shifter vane), while the other end of each mounting recess 102c extends toward the recess structure in a direction parallel to the rotational centerline A of the shift component 22 and communicates with each first recess 102a in a one-to-one correspondence. Thus, when the rotating component 23 is installed on the drive shaft 10, each protrusion on the rotating component 23 can pass through each mounting recess 102c and enter the corresponding first recess 102a.

[0081] In some embodiments, as Figure 6 As shown, the second transmission structure 232 is at least one slot formed on the outer peripheral surface of the rotating component 23, and the slot is, for example, Figure 6 U-shaped grooves as shown (i.e., the opening size remains constant as the depth increases) or as Figure 7 As shown in the C-shaped groove (ie, the opening size decreases with increasing depth), the axial direction of the slot coincides with the radial direction of the rotating component 23. Figure 5 and Figure 7As shown, the first transmission structure 221 is a fork structure formed on the periphery of the shift component 22. The fork structure is, for example, a concave-convex structure formed on the periphery of the shift component 22. The concave-convex structure includes, for example, a convex portion and a concave portion located on both sides of the convex portion. The side surface of the convex portion in the peripheral direction of the shift component 22 can abut against the side surface of the slot of any rotating component 23 when the shift component 22 rotates, thereby driving the rotating component 23 to rotate. The convex portion of the concave-convex structure protrudes radially along the shift component 22, for example. The function of the concave portion in the concave-convex structure is to expose the side surface of the convex portion so that it can abut against the side surface of the slot of any rotating component 23. Two concave portions are provided on both sides of the convex portion to adapt the shift component 22 to two opposite rotation directions of clockwise and counterclockwise, so that the shift component 22 can abut against the side surface of the slot of any rotating component 23 whether it rotates clockwise or counterclockwise. As shown Figure 4 As shown, when the convex portion of the concave-convex structure is inserted into the slot, and the slot opening is parallel to the radial direction of the shift member 22, the shift member 22 stops rotating. At this time, the rotating member 23 is in the non-engaging position, and the convex portion of the rotating member 23 is located in the corresponding second concave channel 102b. As the convex portion of the concave-convex structure continues to rotate from this position, the convex portion of the concave-convex structure moves out of the slot, driving the rotating member 23 to continue rotating until it switches from the non-engaging position to the engaging position.

[0082] When the shift component 22 rotates to any transmission position, the shift fork structure can move into the slot of the rotating component 23 corresponding to the transmission position, and during the movement, it drives the rotating component 23 to rotate and switch from a non-matching position to a matching position. When the shift component 22 continues to rotate in the same direction, the shift fork structure can move out of the slot, and during the movement out, it drives the rotating component 23 to rotate and switch from a matching position to a non-matching position. In other words, when the shift component 22 rotates, the shift fork structure can move into the slot of the corresponding rotating component 23, driving the rotating component 23 to rotate, thereby achieving the shifting operation. When the shift component 22 continues to rotate, the shift fork structure can move out of the slot, returning the rotating component 23 to the non-matching position. The cooperation between the shift fork structure and the slot achieves efficient transmission and improves the accuracy and reliability of the shifting.

[0083] In some embodiments, see Figure 1 、 Figure 4 、 Figure 9 and Figure 10The movable structure 21 includes a first shift cover plate 211 and a second shift cover plate 212, stacked and connected in a direction parallel to the rotational centerline A of the shift member 22. A housing space is formed between the first shift cover plate 211 and the second shift cover plate 212, within which the rotating structure 20 (i.e., the shift member 22 and each rotating member 23) is rotatably disposed. This housing space is, for example, formed by a groove formed in at least one of the opposing surfaces of the first shift cover plate 211 and the second shift cover plate 212. Furthermore, at least two first through-holes 213 are coaxially disposed in the first shift cover plate 211 and the second shift cover plate 212. Each drive shaft 10 is sequentially inserted through each of the first and second shift cover plates 211, 212, along a direction parallel to the rotational centerline A of the shift member 22 (i.e., the direction of movement of the movable structure 21). When the first shift cover 211 and the second shift cover 212 move, the drive shaft 10 that does not move with the moving structure 21 can remain stationary relative to the first shift cover 211 and the second shift cover 212 via the corresponding first through hole 213 .

[0084] By utilizing the accommodation space formed by the first shift cover plate 211 and the second shift cover plate 212, a stable support platform is provided for the shift component 22 and the rotating component 23, enhancing the structural stability of the entire device. Furthermore, the design of the accommodation space allows the shift component 22 and the rotating component 23 to be integrated into the movable structure 21, allowing these components to move as a whole, thereby simplifying the transmission structure and improving the integration of the device. This integrated design not only improves the reliability of the device but also significantly reduces its manufacturing cost. Furthermore, each drive shaft 10 that does not move with the movable structure 21 can utilize the first through-hole 213 to generate relative motion with the movable structure 21.

[0085] In some embodiments, see Figure 1 and Figure 10 The antenna phase adjustment device 100 further includes a first drive module 30, which is in driving connection with at least one of the first shift cover 211 and the second shift cover 212, and is configured to drive the first shift cover 211 and the second shift cover 212 to move in a direction parallel to the rotational centerline A of the shift component 22 (i.e., the movement direction of the movable structure 21). The first drive module 30 is configured to achieve automated control of the device. Of course, in practical applications, the first drive module 30 can be omitted. In this case, the movement of the first shift cover 211 and the second shift cover 212 can be achieved manually.

[0086] Furthermore, in some embodiments, the first drive module 30 includes a first motor 31 and a drive screw 32. One end of the drive screw 32 is connected to the drive shaft of the first motor 31, and the other end passes through a through hole in the first shift cover 211 and a threaded hole in the second shift cover 212, respectively. The external thread of the drive screw 32 engages with the internal thread of the threaded hole. When the first motor 31 drives the drive screw 32 to rotate, the external thread of the drive screw 32 cooperates with the internal thread of the threaded hole to cause the first shift cover 211 and the second shift cover 212 to move relative to the drive screw 32 in the axial direction of the drive screw 32 (i.e., parallel to the rotational centerline A of the shift component 22). In other words, the drive screw 32 functions as a transmission, converting the rotational power of the first motor 31 into linear power along the axial direction of the drive screw 32, and transmitting the linear power to the first shift cover 211 and the second shift cover 212. Of course, in actual applications, the first drive module 30 can also adopt other drive methods, such as using a linear motor to drive the first shift cover 211 and the second shift cover 212. The first motor 31 can be, for example, a high-precision stepper motor to achieve precise driving of the shift components, thereby ensuring that each shift operation is completed accurately.

[0087] In some embodiments, the antenna phase adjustment device 100 further includes a second driving module 40, which is in driving connection with the shift component 22 and is configured to drive the shift component 22 to rotate about the rotation centerline A of the shift component 22. In embodiments including the first driving module 30, since the second driving module 40 independently drives the shift component 22, and the first driving module 30 independently drives the first shift cover plate 211 and the second shift cover plate 212, the rotation control of the shift component 22 can be completely decoupled from the movement control of the first shift cover plate 211 and the second shift cover plate 212, thereby reducing control difficulty and improving device reliability.

[0088] Further, in some embodiments, the second drive module 40 includes a shift lever 42 and a second motor 41, wherein one end of the shift lever 42 is connected to the drive shaft of the second motor 41, and the other end cooperates with the shift component 22 in the direction around the rotation center line A of the shift component 22, and can cooperate to move relative to each other in the direction parallel to the rotation center line A of the shift component 22. The second motor 41 is used to drive the shift component 22 to rotate around the rotation center line A of the shift component 22 through the shift lever 42. In this way, on the basis of the second motor 41 driving the shift component 22 to rotate around the rotation center line A of the shift component 22 through the shift lever 42, the shift lever 42 and the shift component 22 can be allowed to generate relative movement in the direction parallel to the rotation center line A of the shift component 22, that is, when the shift component 22 moves with the moving structure 21, the shift lever 42 remains stationary. As Figure 3 and Figure 9 As shown, in an embodiment in which a first shift cover plate 211 and a second shift cover plate 212 are provided, a center hole 214 is provided on the first shift cover plate 211 for the shift rod 42 to pass through so as to be able to extend into the accommodating space formed by the first shift cover plate 211 and the second shift cover plate 212 to cooperate with the shift component 22.

[0089] There are many ways for the shift lever 42 and the shift component 22 to cooperate in limiting the position in the direction around the rotation center line A of the shift component 22. In some embodiments, for example, Figure 5 As shown, the shift component 22 is provided with a non-circular through-hole 222. The shift rod 42 passes through the non-circular through-hole 222 in a direction parallel to the rotational centerline A of the shift component 22. The outer circumference of the shift rod 42 matches the wall shape of the non-circular through-hole 222. The non-circular through-hole 222 and the non-circular outer circumference of the shift rod 42 cooperate to restrict relative rotation between the shift rod 42 and the shift component 22, thereby enabling the second motor 41, via the shift rod 42, to drive the shift component 22 to rotate about the rotational centerline A of the shift component 22. The outer circumference of the shift rod 42 and the wall shape of the non-circular through-hole 222 may include, for example, polygonal shapes such as quadrilaterals or hexagons, or elliptical or irregular shapes.

[0090] In some embodiments, as Figure 1 and Figure 10 As shown, the antenna phase adjustment device 100 further includes a mounting module, which includes a first drive cover plate 54 having at least two mounting holes 541 defined therein. At least two drive shafts 10 are disposed in a one-to-one correspondence through the at least two mounting holes 541. A buffer component 542 is disposed in each mounting hole 541. The buffer component 542 is configured to immobilize the other drive shafts 10 that do not move with the movable structure 21 while one drive shaft 10 moves with the movable structure 21. This design not only improves the structural stability of the device but also secures and protects the drive shafts 10 through the buffer component 542, ensuring the reliability and stability of the device during operation. The buffer component 542 is, for example, an annular flexible part such as a silicone sleeve, which is arranged around the corresponding drive shaft 10. When the drive shaft 10 moves with the movable structure 21, the drive shaft 10 can overcome the resistance of the silicone sleeve and move relative to the first drive cover plate 54; when the drive shaft 10 does not move with the movable structure 21, the drive shaft 10 can be fixed relative to the first drive cover plate 54 under the action of the resistance of the silicone sleeve.

[0091] In the embodiment provided with the above-mentioned mounting module, the mounting module may further include a second drive cover plate 53 and at least one guide rod 52, wherein the second drive cover plate 53 is relatively arranged on the side of the first shift cover plate 211 away from the second shift cover plate 212; the at least one guide rod 52 is arranged around the rotation center line A of the shift component 22 and is parallel to the rotation center line A of the shift component 22; one end of the guide rod 52 is fixedly connected to the second drive cover plate 53, and the other end passes through the second through hole 215 (such as Figure 9 ), and can, through the second through-hole 215, generate relative movement with the first shift cover plate 211 and the second shift cover plate 212 in a direction parallel to the rotational centerline A of the shift component 22. That is, the first shift cover plate 211 and the second shift cover plate 212 move relative to the guide rod 52. This design not only improves the structural stability of the device but also precisely guides the movable structure 21 through the guide rod 52, ensuring the stability and reliability of the movable structure 21 during movement. Furthermore, the second drive cover plate 53 is provided with at least two first through-holes 531 for correspondingly passing the drive shaft 10 therethrough; and the second drive cover plate 53 is also provided with a second through-hole 532 for passing the shift rod 42 therethrough.

[0092] In addition, if Figure 1 As shown, the mounting module may further include a shell 51, which is used to accommodate and install the motors in the first drive module 30 and the second drive module 40, and provide an installation base for components such as the second drive cover plate 53, the guide rod 52 and the first drive cover plate 54.

[0093] As another technical solution, an embodiment of the present application further provides an antenna device, comprising: a phase shifter and the antenna phase adjustment device 100 provided in an embodiment of the present application. The phase shifter includes at least two phase shifter slides of different frequency bands, which are used to adjust the beam azimuth of the corresponding frequency bands.

[0094] The antenna device provided in the embodiment of the present application can simplify the structure, improve reliability and reduce costs by adopting the above-mentioned antenna phase adjustment device 100 provided in the embodiment of the present application, thereby meeting the high requirements of the communication base station on antenna performance.

[0095] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present application, and the present application is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present application, and such modifications and improvements are also considered to be within the scope of protection of the present application.
