Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more particularly to a phase shifter assembly capable of achieving clamping between a first phase shifter and a second phase shifter without resorting to an inverted structure. Background Art

[0002] In a conventional phase shifter assembly, the first and second phase shifters are clamped together using a sliding plate with an undercut feature to compress the two relatively moving phase shifters. While this ensures a good fit between the sliding plate and the phase plate, sliding friction occurs between the undercut feature of the phase shifter's clamping piece and the phase shifter when the phase shifter adjusts its inclination angle. This causes noticeable scratches on the phase shifter plate as the number of operations increases. This shortens the life of the phase shifter, increases driving tension, and reduces driving efficiency. Summary of the Invention

[0003] The following technical problem exists in the prior art: as the number of operations of the phase shifter assembly in the prior art increases, obvious scratches will appear on the phase shifter plate, thereby shortening the life of the phase shifter.

[0004] In response to the above technical problems, the present disclosure proposes a phase shifter assembly, characterized in that the phase shifter assembly includes:

This eliminates sliding friction between the phase shifter clamp and the first phase shifter, and prevents noticeable scratches on the phase shifter plate with increased operation. This improves the lifespan of the phase shifter assembly and the stability of its electrical performance. In other words, one embodiment of the present disclosure achieves a tight fit between the two phase shifters while addressing the lifespan issues associated with friction between the phase shifter and the clamping device.

[0019] In one embodiment according to the present disclosure, the bridge-type elastomer includes a single-bridge elastomer, a double-bridge elastomer, or an N-bridge elastomer.

[0029] a second reversing mechanism disposed between the second gear and the rack and meshing with the second gear and the rack, respectively, so that a component of a linear velocity of the electrical contact position of the third phase shifter and the fourth phase shifter in a moving direction of the rack is opposite to a moving direction of the rack;

[0030] The rack is configured to drive the fourth phase shifter to move relative to the third phase shifter via the second gear, so as to adjust the inclination angle of the phase shifter assembly.

[0031] In one embodiment of the present disclosure, a combination of the first phase shifter, the second phase shifter, and the first gear, and a combination of the third phase shifter, the fourth phase shifter, and the second gear are arranged in a mirror-symmetrical manner with respect to the rack or are arranged in an array on one side of the rack.

[0032] In one embodiment according to the present disclosure, the phase shifter assembly further includes a shield surrounding the first phase shifter and the second phase shifter.

[0033] In summary, the support member and the elastic member at the end of the first gear achieve a secure clamping connection between the first and second phase shifters, eliminating the need for additional undercut features, such as a phase shifter clamping member.

[0045] In the following detailed description of preferred embodiments, reference will be made to the accompanying drawings that form part of the present disclosure. The accompanying drawings illustrate, by way of example, specific embodiments that can implement the present disclosure. The illustrative embodiments are not intended to be exhaustive of all embodiments according to the present disclosure. It will be understood that other embodiments may be utilized and structural or logical modifications may be made without departing from the scope of the present disclosure. Therefore, the following detailed description is not restrictive, and the scope of the present disclosure is defined by the appended claims.

[0046] The following technical problems exist in the prior art: the phase shifter assembly in the prior art either requires the scale to extend too far beyond the antenna, thereby bringing the risk of product damage and inconvenience in transportation. The longer the scale extends, the smaller the angle, which is contrary to normal logic and low customer satisfaction; or it causes the length of the cable connecting the phase shifter to increase, thereby increasing costs.

[0047] In response to the above technical problems, the present disclosure proposes a phase shifter component. Figure 1 The phase shifter assembly proposed according to the present disclosure is shown, and the phase shifter assembly includes the following components:

[0048] A first phase shifter 1, wherein the first phase shifter 1 has a first through hole;

[0049] The second phase shifter 2 is provided between the first phase shifter 1 and the Figure 1 The upper side in the direction shown and the second phase shifter 2 has a second through hole;

[0050] The first gear 3 is arranged on a side of the second phase shifter 2 away from the first phase shifter 1 (at Figure 1 The upper side in the direction shown) and the first gear 3 has a third through hole, wherein the first through hole, the second through hole and the third through hole are aligned with each other in the assembled state. Here, those skilled in the art should understand that the three through holes here can be mechanically coupled by a certain physical connection method, such as riveting by rivets, threading by screw elements or other connection methods, and the connection method is not necessary for achieving the reversing function;

[0051] a rack 5 configured to drive the second phase shifter 2 to move relative to the first phase shifter 1 via the first gear 3 to adjust the inclination angle of the phase shifter assembly. Those skilled in the art will appreciate that the technical solution of the rack 5 driving the second phase shifter 2 via the first gear 3 does not necessarily require the rack 5 to be directly coupled to the first gear 3; the rack 5 may be indirectly connected to the first gear 3 via other mechanisms; and

[0052] The first reversing mechanism 4 is disposed between the first gear 3 and the rack 5 and meshes with the first gear 3 and the rack 5, respectively, so that a component of the linear velocity of the electrical contact position of the first phase shifter 1 and the second phase shifter 2 in the direction of movement of the rack is opposite to the direction of movement of the rack.

[0053] In the specific use process, the first reversing mechanism 4 is used to realize the linear motion direction of the phase shifter input toward the IN port (for example Figure 1 X direction as shown), the phase shifter inclination angle becomes larger (that is, the component of the linear velocity of the electrical connection position of the second phase shifter 2 and the first phase shifter 1 in the motion input direction is opposite to the input motion direction); the input linear motion direction is opposite to the direction of the IN port (for example Figure 1 Specifically, when the rack 5 moves in the X direction, the teeth of the rack 5 engage with the first reversing mechanism 4 (here, a gear), and the first reversing mechanism 4 rotates clockwise around the central axis. The first reversing mechanism 4 engages with the first gear 3, driving the first gear 3 to rotate counterclockwise around the axis. The first gear 3 drives the second phase shifter 2 to rotate counterclockwise. The velocity component direction of the electrical connection point between the second phase shifter 2 and the first phase shifter 1 in the X direction is X', which is opposite to the X direction, thereby realizing the reverse function of the phase shifter. Conversely, when the rack 5 moves in the X' direction, the teeth of the rack 5 mesh with the first reversing mechanism 4, causing the first reversing mechanism 4 to rotate counterclockwise around the central axis. The first reversing mechanism 4 meshes with the first gear 3, driving the first gear 3 to rotate clockwise around the axis. The first gear 3 then drives the second phase shifter 2 to rotate clockwise. The velocity component direction of the electrical connection point C between the second phase shifter 2 and the first phase shifter 1 in the X direction is X, which is opposite to the input motion direction X', thus realizing the reverse function of the phase shifter.

[0054] While the factory setting requires the inclination angle to be at the minimum position, Figure 1 The rack representing the tilt angle is located at the far left end, so that the part of the scale extending out of the lower end cover of the antenna can be controlled, thereby improving the transportation characteristics of the antenna and reducing the risk of damage.

[0055] The phase shifter assembly disclosed in the present disclosure can achieve a reverse technical solution with the help of the first reversing mechanism, that is, when the linear motion direction input by the phase shifter is toward the IN port, the phase shifter tilt angle becomes larger; when the input linear motion direction is opposite to the IN port, the phase shifter tilt angle becomes smaller. As a result, when the antenna is in the minimum electrical tilt state, the scale will not extend too long from the antenna, reducing the risk of damage during transportation and installation. The scale angle marking method is more logical, increasing customer satisfaction, and will not increase the length of the cable connecting the phase shifter.

[0056] In addition to the aforementioned shortcomings in the relative correlation between the inclination angle and the direction of movement, the phase shifter assembly in the prior art also suffers from another drawback: the conventional method of clamping the first and second phase shifters is to use a sliding plate with an undercut feature to press the two relatively moving phase shifters. Although this achieves a good fit between the sliding plate and the phase plate, when the phase shifter adjusts its inclination angle, sliding friction occurs between the undercut feature of the phase shifter clamping piece and the phase shifter. As the number of operations increases, the phase shifter plate will develop obvious scratches, shortening the life of the phase shifter, increasing the driving tension, and reducing the driving efficiency.

[0057] In order to solve this technical problem, the inventors of the present disclosure proposed the following technical solution: Figure 2 As shown, Figure 2 FIG. 1 shows a schematic diagram of a phase shifter assembly according to another embodiment of the present disclosure. Figure 2 It can be seen that another phase shifter component proposed according to the present disclosure includes:

[0058] A first phase shifter 1, wherein the first phase shifter 1 has a first through hole;

[0059] a second phase shifter 2, wherein the second phase shifter 2 is disposed on one side of the first phase shifter 1 and has a second through hole;

[0060] a first gear 3, the first gear 3 being disposed on a side of the second phase shifter 2 away from the first phase shifter 1 and having a third through hole, wherein the first through hole, the second through hole, and the third through hole are aligned with each other in the assembled state. It should be understood by those skilled in the art that the three through holes can be mechanically coupled by a certain physical connection method, such as riveting with rivets, threaded connection with a threaded element, or other connection methods, and such connection method is not essential for achieving the reversing function;

[0061] a rack (not shown in the figures), the rack being configured to drive the second phase shifter 2 to move relative to the first phase shifter 1 via the first gear 3 so as to adjust the inclination angle of the phase shifter assembly; and

[0062] A support member 8, the support member 8 is used to support the rack,

[0063] The first gear 3 has a terminal elastic body ( Figure 3 The end elastic body 33 is coupled to the support member 8 in the assembled state, so that the support member 8 presses the second phase shifter 2 onto the first phase shifter 1 via the end elastic body 33 .

[0064] exist Figure 2 In the illustrated embodiment, the elastic feature at the end of the first gear 3 contacts the support 8. The force provided by this contact with the support 8 compresses the end of the first gear 3. This compressive force is then transmitted to the second phase shifter 2 through the elastic feature, ensuring that the second phase shifter 2 remains firmly in contact with the first phase shifter 1. This design prevents sliding friction between the first gear 3 and the first phase shifter 1, ensuring that the phase shifter does not damage the first phase shifter 1 during operation, thereby improving the service life of the first phase shifter 1. Low-friction materials can be used for the first gear 3 and the support 8, thereby reducing friction during sliding and improving transmission efficiency. Overall, the structural coordination between the support 8 and the elastic body 33 at the end of the first gear 3 achieves clamping between the first phase shifter 1 and the second phase shifter 2, eliminating the need for additional undercut features such as a phase shifter clamp. Consequently, sliding friction between the phase shifter clamp and the first phase shifter is eliminated, preventing significant scratches on the phase shifter plate with increased operation, thereby improving the service life of the phase shifter assembly and the stability of its electrical performance. In other words, an embodiment of the present disclosure achieves a close fit between the two layers of phase shifters while solving the life problem caused by friction between the phase shifters and the pressing device.

[0065] In addition, the traditional phase shifter assembly uses a spring and plastic shaft fixing method that cannot achieve adjustable preload; and in the actual processing process, due to the manufacturing errors of the plastic shaft, spring, phase shifter thickness and clamping device, the consistency of preload cannot be guaranteed, thus affecting the electrical performance of the product. Figure 2 Also shown are the first screw 6 and the first nut 7. Figure 3 The first gear 3 shown, Figure 4 The first screw 6 is shown and Figure 5 and Figure 6Two different configurations of the elastic compression plate structure included in the first nut 7 are shown. As can be seen from the aforementioned figures, the phase shifter assembly can also include a first screw 6 and a first nut 7. In the assembled state, the first screw 6 passes through the first, second, and third through-holes and couples with the first nut 7 to provide a preload between the first phase shifter 1, the second phase shifter 2, and the first gear 3. In other words, the present disclosure achieves adjustable preload between two layers of phase shifters, eliminates the effects of thickness and tolerance of the phase shifter and its clamping device on preload accuracy, ensures preload consistency, and ensures the stability of the phase shifter's electrical performance.

[0066] Preferably, at least a portion of the cross-section of the first screw 6 has a first D-shaped cross-section, and at least one of the second and third through-holes has a second D-shaped cross-section that complements the first D-shaped cross-section. Those skilled in the art will appreciate that both the second and third through-holes may have a second D-shaped cross-section that complements the first D-shaped cross-section, or alternatively, only one of the second and third through-holes may have a second D-shaped cross-section that complements the first D-shaped cross-section, as long as the first screw 6 does not rotate with the rotation of the first nut 7. This prevents the first screw 6 from rotating when the first nut 7 rotates, thereby providing a preload force between the first and second phase shifters 1 and 2 and the first gear 3. More preferably, the first nut 7 includes an elastic compression member that is configured to elastically deform to provide an adjustable preload force between the first and second phase shifters 1 and 2 and the first gear 3. Specifically, the first screw 6 and the first elastic nut 7 cooperate to provide pretightening. When the torque reaches a certain value, the preload force between the second phase shifter 2 and the first phase shifter 1 remains constant. By adjusting the torque, the elastic characteristics of the first elastic nut 7 and the amount of interference with the first gear 3 are altered, achieving rapid adjustability of the clamping force. In this embodiment, the preload force is independent of the thickness of the second phase shifter 2, the first phase shifter 1, and the first gear 3. This eliminates the influence of the thickness and matching tolerances of the first phase shifter 1, the second phase shifter 2, and the first gear 3 on the preload accuracy, ensuring the consistency of the preload force.

[0067] from Figure 5 and Figure 6It can be seen that the elastic pressure piece member has a cantilevered elastic structure evenly distributed in the circumferential direction around the center position of the first nut 7. Preferably, the elastic pressure piece member has a ratchet buckle and the first gear 3 has at least one recess 31 around the third through hole. The ratchet buckle mechanically cooperates with one of the at least one recess 31 in the assembled state. This can prevent the first nut 7 from loosening during use, thereby ensuring the stability of the phase shifter assembly. In other words, the ratchet structure prevents the compression nut from loosening, ensuring stable positive pressure between the phase shifters and the reliability of the RF performance.

[0068] Furthermore, the existing phase shifter design adopts a cantilever elastic body structure, which ensures the sliding plate is pressed tightly by applying a preload force on the elastic body; however, in actual application, the cantilever elastic structure will cause the preload force to change due to fatigue and creep life problems. Figure 3 As shown, the first gear 3 has a bridge-type elastic body 32 associated with the line direction of the first phase shifter 1 and / or the second phase shifter 2, so as to apply a force to the second phase shifter 2 toward the first phase shifter 1 in the assembled state. The bridge-type elastic body 32 includes a single-bridge elastic body, a double-bridge elastic body, or an N-bridge elastic body. The characteristics of the bridge-type elastic body 32 on the first gear 3 can be distributed along the line direction of the first phase shifter 1 and the second phase shifter 2, and the positive pressure provided by the bridge-type elastic body 32 acts evenly directly above the line, ensuring good positive pressure and thus achieving more stable electrical performance. In other words, the above-mentioned technical features improve the fatigue and creep life of the phase shifter pressing parts, thereby ensuring the stability of the structure and electrical performance.

[0069] also, Figure 2 The phase shifter assembly shown can also include Figure 1 The first reversing mechanism 4 shown in FIG. 1 , but those skilled in the art should understand that Figure 2 The purpose of the technical solution shown is to solve the technical problem that when the phase shifter assembly is working, the first phase shifter 1 is damaged due to the undercut feature set by the need for compression, thereby affecting the life of the phase shifter assembly. Therefore, the first reversing mechanism 4 for achieving reversal is not necessarily required. The life problem can also be solved without the first reversing mechanism 4. However, having the first reversing mechanism 4 can more preferably solve the reversal problem at the same time. Figure 7As shown, the first reversing mechanism 4 is disposed between the first gear 3 and the rack 5 and meshes with the first gear 3 and the rack 5, respectively, so that the component of the linear velocity of the electrical contact position of the first phase shifter 1 and the second phase shifter 2 in the direction of motion of the rack is opposite to that of the rack. The first reversing mechanism includes an odd number of gears. Preferably, the first reversing mechanism 4 includes a single gear. More preferably, the first gear and the second phase shifter are integrally formed.

[0070] like Figure 8 As shown, in an example according to the present disclosure, the phase shifter assembly further includes: a third phase shifter, the third phase shifter having a fourth through hole; a fourth phase shifter, the fourth phase shifter being arranged on one side of the third phase shifter and the fourth phase shifter having a fifth through hole; a second gear, the second gear being arranged on a side of the fourth phase shifter away from the third phase shifter and the second gear having a sixth through hole, wherein the fourth through hole, the fifth through hole and the sixth through hole are aligned with each other in the assembled state; and a second reversing mechanism, the second reversing mechanism being arranged between the second gear and the rack and meshing with the second gear and the rack respectively, so that the component of the linear velocity of the electrical contact position of the third phase shifter and the fourth phase shifter in the direction of movement of the rack is opposite to the direction of movement of the rack, wherein the rack is constructed to drive the fourth phase shifter to move relative to the third phase shifter via the second gear to adjust the inclination angle of the phase shifter assembly. In addition, as Figure 8 As shown, the combination of the first phase shifter 1, the second phase shifter 2, the first gear 3 and / or the first reversing mechanism 4 and the combination of the third phase shifter, the fourth phase shifter, the second gear and the second reversing mechanism are arranged in a mirror-symmetrical manner with respect to the rack 5'' or arranged in an array on one side of the rack 5'', that is, Figure 8 The illustrated phase shifter assembly may or may not include the first reversing mechanism 4. In other words, the corresponding structures can be arranged in a mirrored or array configuration, sharing the same rack, enabling transmission of multiple phase shifters and saving additional space. Preferably, the phase shifter assembly also includes a shield surrounding the first and second phase shifters to ensure the RF performance of the phase shifter assembly.

[0071] Figure 9 FIG2 shows a schematic diagram of a phase shifter assembly according to another embodiment of the present disclosure. Figure 8 The difference is that in Figure 9In the phase shifter assembly shown, two phase shifter assemblies each having a reversing mechanism such as a gear are placed on both sides of the rack 5 ′′′, so that one rack can drive the two phase shifter assemblies.

[0072] Although different exemplary embodiments of the present disclosure have been described, it will be apparent to those skilled in the art that different changes and modifications can be made which can achieve one or more of the advantages of the present disclosure without departing from the spirit and scope of the present disclosure. For those skilled in the art, other components performing the same function may be appropriately replaced. It will be understood that the features explained herein with reference to a particular figure may be combined with features of other figures, even in those cases where this is not explicitly mentioned. In addition, the method of the present disclosure may be implemented in either a software implementation using appropriate processor instructions or in a hybrid implementation utilizing a combination of hardware logic and software logic to achieve the same result. Such modifications to the scheme according to the present disclosure are intended to be covered by the appended claims.
