Technical Field

[0001] The present invention relates to the technical field of base station antennas, and particularly to an antenna phase shifter structure with multiple combination modes. Background Art

[0002] In a wireless communication system, as a key component for adjusting the antenna beam direction and optimizing the signal transmission efficiency, the performance stability and adjustment flexibility of the antenna phase shifter are crucial for ensuring communication quality. Traditional antenna phase shifter structures are often designed in a relatively single way, making it difficult to meet the requirements of modern wireless communication systems for versatility, high integration, and flexible configuration.

[0003] Specifically, traditional antenna phase shifters usually adopt a fixed structure design, with a limited phase adjustment range and difficulty in achieving synchronous or independent adjustment of multiple phase shifters. In addition, the installation and maintenance processes of traditional phase shifters are relatively cumbersome, requiring a large amount of time and manpower. Especially in complex multi-antenna array systems, these problems are particularly prominent, seriously affecting the overall performance and scalability of the system.

[0004] In recent years, with the rapid development of wireless communication technologies, especially the advancement of 5G and future 6G technologies, higher requirements have been put forward for the performance of antenna phase shifters. Modern wireless communication systems not only require antenna phase shifters to have precise phase adjustment capabilities but also require them to be flexibly configured to adapt to communication requirements in different scenarios. Therefore, there is an urgent need in the industry for an antenna phase shifter structure with multiple combination modes to meet the requirements of modern wireless communication systems for high performance, high integration, and flexible configuration.

[0013] As a preferred technical solution, both the single-layer phase adjustment component and the lower layer phase adjustment component include: a rack, and the rack passes through the guide rail on the single-layer mounting seat assembly or the guide rail on the lower mounting seat assembly.

[0014] As a preferred technical solution, both the single-layer phase adjustment component and the lower layer phase adjustment component include: an idler wheel. A shaft rod is provided on the mounting seat on the side close to the concave-convex jigsaw structure, and the idler wheel is sleeved on the shaft rod.

[0015] As a preferred technical solution, both the single-layer phase shifter assembly and the lower-layer phase shifter assembly include: a first slide clip and a second slide clip. The first slide clip and the second slide clip are respectively located at both ends of the phase shifter PCB, and the phase shifter PCB and the lower mounting base are clamped between the first slide clip and the second slide clip. One side of the idler gear meshes with the rack, and the other side of the idler gear meshes with the gear on the first slide clip, driving the rack to drive the first slide clip to swing back and forth through the idler gear, thereby adjusting the phase of the phase shifter PCB.

[0016] As a preferred technical solution, a phase adjustment groove is provided on the mounting base. A first insertion rod and a second insertion rod are connected to the first slide clip. The heights of the first insertion rod and the second insertion rod are equal. The first insertion rod passes through the phase adjustment groove and is inserted into the first set hole on the second slide clip, and the second insertion rod passes through the mounting base and is inserted into the second set hole on the second slide clip to realize the clamping connection between the first slide clip and the second slide clip.

[0017] As a preferred technical solution, a plurality of buckle mounting holes are provided on one end face of the mounting base, and a plurality of buckles are connected to the other end face of the mounting base.

[0020] As a preferred technical solution, coaxial cable mounting grooves are correspondingly provided at the edge of the mounting base, and a coaxial cable is provided in the coaxial cable mounting groove. The coaxial cable is used to connect the phase shifter PCB to an external circuit.

[0021] An antenna phase shifter structure with multiple combination methods provided by the present invention has the following

[0022] Beneficial effects:

[0023] 1) This structure can accurately adjust the phase of the phase shifter. At the same time, through a unique installation design, multiple phase shifters can be conveniently combined together to achieve synchronous drive. This design not only improves the flexibility and scalability of the system, but also greatly simplifies the installation and maintenance process and reduces costs.

[0024] 2) The single-layer phase adjustment component is used to achieve simultaneous phase adjustment of each phase shifter PCB in the single-layer mounting seat component. The mounting seat, phase adjustment component, etc. are all precisely machined and assembled to ensure their motion accuracy and stability. This not only helps to reduce the influence of mechanical wear and vibration on the phase adjustment accuracy, but also ensures that the phase adjustments of all phase shifter PCBs are consistent. After the lower-layer phase adjustment component is snap-connected to the upper-layer phase adjustment component, the lower-layer phase adjustment component can drive the upper-layer phase adjustment component to simultaneously adjust the phase of the upper and lower layers of phase shifter PCBs. This design utilizes the linkage of the mechanical structure to enable the phase adjustments of the upper and lower layers to be synchronized and maintain high precision.

[0025] By installing the phase shifter PCB on multiple mounting seats and designing the splicing method of the single-layer mounting seat component and the upper and lower-layer mounting seat components, a modular design of the phase shifter is achieved. This design enables multiple phase shifters to be conveniently combined together to form a larger-scale phase adjustment system. The upper and lower-layer mounting seats are connected by a snap connection method, which not only simplifies the installation process, but also improves the stability and reliability of the system. At the same time, this snap connection structure is also convenient for disassembly and maintenance, reducing the operating cost of the system.

[0026] Through the snap connection of the lower-layer phase adjustment component and the upper-layer phase adjustment component, and the unified control of the single-layer phase adjustment component, synchronous drive of multiple phase shifters is achieved. This synchronous drive method not only improves the flexibility and scalability of the system, but also ensures the consistency and accuracy of all phase shifters during the phase adjustment process.

[0027] 3) The antenna phase shifter uses a concave-convex jigsaw structure and an interlocking structure to achieve horizontal splicing combination, vertical splicing combination, and horizontal-vertical splicing combination. This structure simultaneously realizes co-rail after horizontal splicing and coaxial vertical splicing, so that transmission modes such as one-to-one, one-to-two, one-to-three, one-to-four, and two-to-two can be achieved to meet various usage scenarios.

Detailed implementation manners

[0038] The preferred implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] As Figures 1-5As shown in the figure, the present invention provides an antenna phase shifter structure with multiple combination methods, including: a plurality of mounting seats 1, on which a phase shifter PCB 2 is provided. Every two mounting seats 1 are spliced to form a single-layer mounting seat assembly and / or an upper and lower layer mounting seat assembly. The upper and lower layer mounting seat assembly includes: a lower mounting seat 1 and an upper mounting seat 1 stacked and clamped with it up and down. The single-layer mounting seat assembly is provided with a single-layer phase adjustment component, the lower mounting seat is provided with a lower layer phase adjustment component, and the upper mounting seat is provided with an upper layer phase adjustment component;

[0040] The single-layer phase adjustment component is used to realize the simultaneous phase adjustment of each phase shifter PCB 2 in the single-layer mounting seat assembly;

[0041] And / or the lower layer phase adjustment component is clamped with the upper layer phase adjustment component to realize the simultaneous phase adjustment of the phase shifter PCB 2 on the upper mounting seat 1 and the phase shifter PCB 2 on the lower mounting seat 1 driven by the lower layer phase adjustment component driving the upper layer phase adjustment component.

[0042] The present invention proposes an antenna phase shifter structure with multiple combination methods. This structure can accurately adjust the phase of the phase shifter. At the same time, through a unique installation design, multiple phase shifters can be conveniently combined together to achieve synchronous drive. This design not only improves the flexibility and scalability of the system, but also greatly simplifies the installation and maintenance process and reduces costs.

[0043] Preferably, as Figure 6 shown, the phase shifter PCBs 2 are correspondingly arranged at both ends of the mounting seat 1. The mounting seat 1 is provided with a concave-convex jigsaw structure 10. Every two adjacent mounting seats 1 are spliced through the concave-convex jigsaw structure 10 to form a guide rail 12 on the lower mounting seat assembly and / or a guide rail 12 on the upper mounting seat assembly and / or a guide rail 12 on the single-layer mounting seat assembly, and the guide rails on two adjacent mounting seats are coaxial and co-railed 13;

[0044] The concave-convex jigsaw structure 10 can ensure accurate docking when every two adjacent mounting seats 1 are spliced. This design avoids the misalignment between the phase shifter PCBs 2 caused by installation errors, thus ensuring the accuracy of phase adjustment;

[0045] Through the close cooperation of the concave-convex jigsaw structure 10, a stable positioning relationship can be formed between the mounting seats 1, which helps to keep the relative positions of the phase shifter PCBs 2 unchanged during subsequent installation, debugging and maintenance processes, and further improves the stability and reliability of the system; the guide rails 12 formed on the spliced mounting seat assembly provide a convenient path for the adjustment of the phase shifter PCBs 2. These guide rails not only ensure the smooth movement of the phase shifter PCBs 2 during the adjustment process, but also ensure the accuracy of the adjustment direction;

[0046] The coaxial and common rail design of the guide rails 13 on two adjacent mounting seats 1 means that in a multi-layer or complex combination of mounting seat assemblies, all the guide rails 12 maintain the same axis, which helps to achieve the synchronization and consistency of multiple phase shifter PCBs 2 during the adjustment process, thereby improving the performance of the entire system;

[0047] The design of the concave-convex puzzle structure 10 and the guide rails 12 greatly simplifies the installation process of the mounting seat assembly. The operator only needs to sequentially splice each mounting seat 1 according to the guidance of the puzzle structure, without complex calibration and adjustment steps;

[0048] During the maintenance process, if it is necessary to replace or repair a certain phase shifter PCB 2, the operator can easily slide it out through the guide rail 12 and perform the corresponding operations. This design not only improves the maintenance efficiency but also reduces the maintenance cost;

[0049] The design of the concave-convex puzzle structure 10 and the guide rails 12 endows the mounting seat with a high degree of modularity, which means that the user can easily add or remove mounting seats according to needs, thereby realizing the scalability of the system;

[0050] Through different splicing methods, the user can flexibly combine various forms of mounting seat assemblies such as single-layer, upper and lower layers, etc. This flexibility helps to meet the requirements in different application scenarios and further improves the applicability of the system.

[0051] Preferably, as Figures 2-5 shown, both the single-layer phase modulation component and the lower-layer phase modulation component include: a rack 3, and the rack 3 passes through the guide rail 12 on the single-layer mounting seat assembly or the guide rail 12 on the lower-layer mounting seat assembly;

[0052] The close fit between the rack 3 and the guide rail 12 ensures the precise positioning of the phase modulation mechanism during movement. Since both the rack 3 and the guide rail 12 are precision machined and assembled, the clearance between them is very small, which helps to reduce the problem of inaccurate phase adjustment caused by movement errors;

[0053] The design of the rack 3 and the guide rail 12 makes the installation process more convenient. The operator only needs to insert the rack 3 along the guide rail 12 and fix it, without complex calibration and adjustment steps;

[0054] During the maintenance process, if it is necessary to check or replace the components in the phase modulation mechanism, the operator can easily slide the rack 3 out through the guide rail 12 and perform the corresponding operations. This design not only improves the maintenance efficiency but also reduces the maintenance cost;

[0055] The design of the rack 3 and the guide rail 12 enables the single-layer phase modulation component and the lower-layer phase modulation component to have a high degree of modularity, which means that users can easily add or remove phase modulation components according to needs, thus realizing the scalability of the system;

[0056] Through different splicing methods, users can flexibly combine various forms of phase modulation components such as single-layer, upper and lower layers. This flexibility helps to meet the requirements in different application scenarios and further improves the applicability of the system.

[0057] Preferably, as Figures 1-2 shown, both the single-layer phase modulation component and the lower-layer phase modulation component include: an idle pulley 4, a shaft rod 15 is provided on the mounting seat close to the concave-convex puzzle structure 10, and the idle pulley 4 is sleeved on the shaft rod 15;

[0058] The idle pulley 4 changes the rotation direction of the driven wheel. In the phase shifter structure, the idle pulley 4 can ensure that the transmission mechanism in the phase modulation component can move in a predetermined direction, thereby realizing phase adjustment;

[0059] Since the idle pulley 4 meshes with the gears on the adjacent rack 3 and the gears on the first slide clip 5 at the same time, it can change the rotation direction of one of the transmission components to be the same as or opposite to that of the other transmission component;

[0060] The idle pulley 4 can also be used to adjust the pressure angle of the transmission system. The pressure angle is an important parameter in the transmission system, which determines the contact force and wear between the transmission components. There are at least two idle pulleys 4, and they are correspondingly arranged on both sides of the gear on the first slide clip 5 and mesh with it. The gear on the first slide clip 5 is arc-shaped. By adjusting the position and number of the idle pulleys, the pressure angle distribution of the transmission system can be changed, thereby optimizing the transmission performance, reducing wear and failures; In addition, in the multi-layer phase modulation component, the idle pulley 4 can also play a role in synchronous drive. By cleverly designing the number and position of the idle pulley 4, it can ensure that the upper and lower layer phase modulation components move synchronously during the phase adjustment process, thereby realizing more precise phase adjustment. This synchronous drive mechanism helps to improve the overall performance and stability of the system;

[0061] The design of the idle pulley 4 also simplifies the installation and maintenance process; Since the idle pulley 4 only plays a transitional and transmission role, it does not require additional drive devices or complex control mechanisms, which makes the installation and maintenance of the phase shifter structure simpler and more convenient.

[0062] Preferably, as Figures 1-2As shown, both the single-layer phase modulation component and the lower-layer phase modulation component include: a first slide clip 5 and a second slide clip 14. The first slide clip 5 and the second slide clip 14 are respectively located at both ends of the phase shifter PCB 2, and clamp the phase shifter PCB 2 and the lower mounting base 1 between the first slide clip 5 and the second slide clip 14. One side of the idler gear 4 meshes with the rack 3, and the other side of the idler gear 4 meshes with the gear on the first slide clip 5, dragging the rack 3 to drive the first slide clip 5 to swing back and forth through the idler gear 4, thereby adjusting the phase of the phase shifter PCB 2;

[0063] By dragging the rack 3, with the idler gear 4 as the transmission intermediary, meshing with the rack 3 and the gear on the first slide clip 5 respectively, this design allows precise control of the swing angle of the first slide clip 5 through external operations (such as manually dragging the rack 3 or electrically driving the rack 3). Since the first slide clip 5 and the second slide clip 14 clamp the phase shifter PCB 2 and the lower mounting base 1 in the middle, the swing of the first slide clip 5 will drive the position of the phase shifter PCB 2 relative to the lower mounting base 1 to change, thereby achieving precise phase adjustment;

[0064] Since the idler gear 4 meshes continuously with the gear on the rack 3 and the gear on the first slide clip 5, dragging the rack 3 can smoothly drive the first slide clip 5 to swing back and forth. This continuous motion characteristic enables the phase adjustment to be very smooth and continuous. They can also reduce phase fluctuations caused by vibration or shock, avoiding phase jumps or unstable situations, which is very important for communication systems that require precise control of phase changes;

[0065] Using the idler gear 4 and the rack 3 as the transmission mechanism can greatly simplify the structural design of the phase modulation component, which not only reduces the manufacturing cost but also makes installation and maintenance simpler and more convenient.

[0066] Preferably, as Figures 1-5 shown and Figure 7 shown, a phase modulation slot (not shown) is provided on the mounting base 1. A first insertion rod 52 and a second insertion rod 53 are connected to the first slide clip 5. The height of the first insertion rod 52 is equal to the height of the second insertion rod 53. The first insertion rod 52 passes through the phase modulation slot (not shown) and is inserted into the first sleeve hole 141 on the second slide clip, and the second insertion rod 53 passes through the mounting base 1 and is inserted into the second sleeve hole 142 on the second slide clip to realize the clamping connection between the first slide clip 5 and the second slide clip 14;

[0067] The first insertion rod 52 and the second insertion rod 53 respectively pass through different sleeve holes on the phase adjustment slot (not shown) and the second sliding piece clamp 14, forming a stable clamping structure. This design ensures a firm and reliable connection between the first sliding piece clamp 5 and the second sliding piece clamp 14, and it is not easy to loosen. Through the clamping structure, the first sliding piece clamp 5 and the second sliding piece clamp 14 can be closely fitted together, enhancing the stability of the entire mounting base, helping to reduce the impact of vibration and shock on the mounting base, and improving the overall performance of the system.

[0068] The phase adjustment slot (not shown) is arc-shaped. The opening of the phase adjustment slot (not shown) enables the first sliding piece clamp 5 to slide along the phase adjustment slot (not shown) within a certain range, thereby realizing the phase adjustment of the phase shifter PCB 2. This design provides precise phase adjustment ability, enabling the system to meet different phase requirements. The heights of the first insertion rod 52 and the second insertion rod 53 are equal, and they are respectively inserted into the first sleeve hole 141 and the second sleeve hole 142 on the second sliding piece clamp. This matching method ensures that the first sliding piece clamp 5 can maintain stability and accuracy during the sliding process, avoiding phase adjustment errors caused by inconsistent insertion rod heights.

[0069] Through the cooperation of the insertion rod and the sleeve hole, the first sliding piece clamp 5 and the second sliding piece clamp 14 can be quickly installed together without additional fixing devices or complex installation steps, helping to save installation time and cost. When it is necessary to maintain or replace the phase shifter PCB 2, simply disassemble the clamping structure between the first sliding piece clamp 5 and the second sliding piece clamp 14. This design makes the maintenance work simpler and more efficient.

[0070] Preferably, as Figure 3 and Figure 5 shown, one end face of the mounting base 1 is provided with a plurality of buckle mounting holes 6, and the other end face of the mounting base 1 is connected with a plurality of buckles 7. The buckles 7 of the upper mounting base are inserted into the buckle mounting holes 6 of the lower mounting base to realize the upper and lower stacking and clamping connection of the upper mounting base 1 and the lower mounting base 1.

[0071] Through the cooperation of the buckle 7 and the buckle mounting hole 6, the upper mounting base 1 can be easily inserted and fixed on the lower mounting base 1 without additional fixing devices or complex installation steps. When it is necessary to disassemble or reconfigure the mounting base, simply pull out the buckle 7 of the upper mounting base from the buckle mounting hole 6 of the lower mounting base, and the operation is simple and fast.

[0072] The tight cooperation between the buckle 7 and the buckle mounting hole 6 ensures a firm connection between the upper and lower mounting bases 1. This design helps to prevent the mounting base 1 from loosening or displacing under vibration or shock conditions.

[0073] The design of the buckle 7 and the buckle mounting hole 6 enables the mounting seat assembly to have a high degree of modularity. Users can easily add or remove the mounting seat assembly according to their needs, realizing the scalability of the system to adapt to different application scenarios and requirements.

[0074] The design of the buckle 7 and the buckle mounting hole 6 enables the mounting seat assembly to maintain a compact structure when stacked, which helps to maximize the utilization of limited space resources, especially in application scenarios with high space requirements.

[0075] Preferably, as Figure 3 、lift 4, Figure 5 and Figure 8 shown, the upper phase modulation component includes: a third slide clip 11. The third slide clip 11 and the second slide clip 14 are respectively located at both ends of the phase shifter PCB 2, and clamp the phase shifter PCB 2 and the upper mounting seat 1 between the third slide clip 11 and the second slide clip 14. A third insertion rod 111 and a fourth insertion rod 112 are connected to the third slide clip 11. The height of the third insertion rod 111 is greater than the height of the fourth insertion rod 112. The third insertion rod 111 passes through the phase modulation slot and is sequentially inserted into the first set hole 141 on the upper second slide clip and the first set hole 54 on the lower first slide clip to realize the simultaneous phase modulation of the phase shifter PCB 2 on the upper mounting seat 1 and the phase shifter PCB 2 on the lower mounting seat 1 by the lower first slide clip 5 driving the upper third slide clip 11;

[0076] The third slide clip 11 and the second slide clip 14 are respectively located at both ends of the phase shifter PCB 2. Through the clamping action, it is ensured that the phase shifter PCB 2 will not move or deform during the phase modulation process, thus ensuring the accuracy and stability of the phase modulation;

[0077] The third insertion rod 111 and the fourth insertion rod 112 are respectively connected to the third slide clip 11, and the height of the third insertion rod 111 is greater than that of the fourth insertion rod 112. This design enables the third insertion rod 111 to pass through the phase modulation slot (not shown) and be sequentially inserted into the first set hole 141 on the upper second slide clip and the first set hole 54 on the lower first slide clip. When the phase of the phase shifter PCB 2 needs to be adjusted, the position of the phase shifter PCB 2 in the phase modulation slot can be changed by moving the first slide clip 5 (due to the connection of the third insertion rod 111 and the fourth insertion rod 112, the upper second slide clip 14 and the upper third slide clip 11 will be driven simultaneously), so as to realize the simultaneous phase modulation of the upper and lower phase shifter PCBs 2;

[0078] With this design, the user only needs to operate one sliding clip (such as the first sliding clip 5) to adjust the phases of the upper and lower layers of the phase shifter PCB2 simultaneously, greatly simplifying the phase adjustment operation; due to the tight fit between the insertion rod and the socket hole, and the firm clamping of the phase shifter PCB2 by the sliding clip, this design can ensure the accuracy and stability of phase adjustment, meeting the requirements in various application scenarios;

[0079] This design makes the entire phase adjustment component have a compact structure and a reasonable layout, helping to reduce space occupation and improve the overall reliability of the system; by adjusting the phases of the upper and lower layer phase shifter PCBs 2 simultaneously, the errors and cumulative errors caused by individual adjustment can be reduced, improving the overall performance and stability of the system.

[0080] Preferably, as Figures 1-6 shown, a phase shifter sliding piece (not shown) is provided between the phase shifter PCB2 and the first sliding clip 5 or the third sliding clip 11;

[0081] The phase shifter sliding piece (not shown) is a key component in the phase shifter. By operations such as sliding or rotating, it can change the length of the signal transmission path or parameters such as capacitance and inductance on the phase shifter PCB2, thereby achieving phase adjustment, and can ensure the accurate transmission of signals and the stable operation of the system;

[0082] The phase shifter sliding piece (not shown) also plays a role in protecting the phase shifter PCB2 and the circuit. During the sliding or rotating process, the phase shifter sliding piece can prevent the circuit on the phase shifter PCB2 from being mechanically damaged or worn, and at the same time prevent pollutants such as dust and moisture from entering the circuit interior, ensuring the long-term stability and reliability of the phase shifter PCB2.

[0083] Preferably, as Figure 1 shown, a coaxial cable installation groove 8 is correspondingly provided at the edge of the mounting seat 1, and a coaxial cable 9 is provided in the coaxial cable installation groove 8. The coaxial cable 9 is used to connect the phase shifter PCB2 to an external circuit (not shown);
