Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication antennas, in particular to a phase shifter wiring structure and an antenna. BACKGROUND

[0002] With the development of mobile communication technology, under the system demand, the mainstream configuration of antenna design gradually changes to integrate multiple systems and multiple modes into one antenna. At the same time, due to the limitation of the windward area of the antenna, the multi-system integrated antenna not only needs to meet the integration of multiple arrays in one antenna, but also needs to realize the miniaturization of the cross section, so that the internal structure of the antenna is compact. If the phase shift network at the back of the antenna is arranged in the conventional way, that is, the phase shift network is arranged parallel to the reflector plate, it often causes interference. In order to avoid such situations, the industry generally arranges the phase shifter in a way that the inner cavity of the phase shifter is perpendicular to the reflector plate. Although this method can arrange multiple phase shift networks, the cable welding method of the existing phase shifter main feed end and output end is difficult to adapt to this cavity arrangement. The existing technology usually adopts two wiring methods. One is to weld the cable along the longitudinal direction of the phase shifter cavity and lie on the narrow side, which makes the bending radius of the cable wiring large, and the length of the cable becomes longer. The other is to weld the cable perpendicular to the longitudinal direction of the cavity on the narrow side. Due to the requirement of the bending radius of the cable, the cavity is arranged high, thereby increasing the space at the back of the antenna and making the thickness of the antenna larger.

DETAILED DESCRIPTION

[0020] The present application will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the application are shown. The application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of thorough and complete disclosure of the application and are fully presented by way of exemplification of the application. Embodiments of the application are described herein with reference to the accompanying drawings, in which:

[0021] The prior art generally adopts two wiring modes, one of which is to lay the cable flat on the narrow side in the longitudinal direction of the cavity, which results in a large bending radius of the cable wiring, making the length of the cable longer, and the other is to weld the cable vertically on the narrow side of the cavity, and the phase shifter is arranged vertically. Due to the requirement of cable bending radius, the cavity needs to be erected higher, resulting in an increase in the space behind the antenna and the thickness of the antenna, thereby increasing the space occupancy and easily causing interference.

[0024] Since the antenna is mostly placed in an open position or arranged at a high position to prevent surrounding trees or floors from blocking the antenna and thereby affecting signal transmission, when the outside is windy, the wind force will directly act on the antenna plate, causing the connection between the connecting frame of the antenna plate and the base to be stressed for a long time, increasing the wear and tear of the two, causing a gap between the two to vibrate, affecting the signal reception of the device.

[0027] As shown in Figures 5-7 , the force applying assembly includes: two first gears 208, which are rotationally connected to the fixed frame 204 and located on the two sides of the support frame 202, and the first gear 208 is engaged with the adjacent arc-shaped rack 205; two first elastic push rods 209, which are fixedly connected to the fixed frame 204, and the extension end of the first elastic push rod 209 is fixedly connected with a first rack frame 210, and the first rack frame 210 is engaged with the adjacent first gear 208; two second elastic push rods 211, which are fixedly connected to the rotating platform of the rotating base 201, and the fixed parts of the two second elastic push rods 211 are fixedly connected and communicated with the fixed parts of the two first elastic push rods 209 through a first flexible pipe, and the extension end of the second elastic push rod 211 is fixedly connected with an abutting plate 212; a steering assembly, which is arranged on the rotating base 201 and is used to individually press the extension end of any one of the second elastic push rods 211.

[0028] In the above scheme, the two first elastic push rods 209 are respectively located on the two sides of the support frame 202, i.e. the front and back of the matrix antenna board 203, the outer parts of the arc-shaped rack 205, the first gear 208 and the first rack frame 210 are electroplated with a rust-proof coating, such as a zinc-based coating, to prolong the service life of the three, the fixed parts of the first elastic push rod 209, the fixed parts of the second elastic push rod 211 and the first flexible pipe are filled with hydraulic oil, and the first flexible pipe has sufficient length to facilitate the arrangement and fixation of the first flexible pipe.

[0029] As shown in Figure 7 and Figure 8As shown, the steering assembly comprises: a first servo motor 301 fixedly connected to a rotating base 201, the rotating base 201 being provided with a wind detector for detecting wind direction and wind speed; a second gear 302 fixedly connected to an output shaft of the first servo motor 301; a gear ring 303 rotatably connected to the rotating base 201, the second gear 302 being engaged with the gear ring 303; a driving ring 304 rotatably connected to the gear ring 303, two abutting plates 212 being in extrusion fit with the driving ring 304; a first adjusting assembly arranged on the gear ring 303 and used for changing the rotation angle of the driving ring 304; two second elastic push rods 211 being located on the same side of a rotating platform of the rotating base 201 and having different directions of the extension ends; and the abutting plates 212 on the extension ends of the two second elastic push rods 211 being in extrusion fit with the two sides of the driving ring 304 respectively.

[0030] In the above scheme, the first servo motor 301 is externally provided with a shielding shell (not shown in the figure) for preventing external water vapor and dust from entering the inside thereof, protecting the electronic elements inside the first servo motor 301, the second gear 302 and the gear ring 303 are externally plated with a rust-proof coating, such as a zinc-based coating, for prolonging the service life of the two, the driving ring 304 is in a circular ring structure, the outside of the driving ring 304 is externally plated with a wear-resistant coating, such as a hard chromium plating, for slowing down the friction loss with the abutting plates 212 and prolonging the service life of the two, the two second elastic push rods 211 are located on the front side of the matrix antenna plate 203, the fixed part of the second elastic push rod 211 corresponding to the abutting plate 212 located above is in communication with the first elastic push rod 209 close to the front side of the matrix antenna plate 203, the rest of the first elastic push rods 209 and the second elastic push rods 211 are in communication with each other, the outside of the abutting plate 212 is externally plated with a wear-resistant coating, such as a hard chromium plating, for reducing the friction loss of the abutting plate 212 and prolonging the service life, by detecting the wind flow size of the outside and the wind area change of the matrix antenna plate 203, the support force of the two counter supporting shafts 206 on the support frame 202 is dynamically adjusted, the force balance of the support frame 202 under the wind force environment is maintained, the abrasion between the support frame 202 and the rotating base 201 is reduced, and the signal receiving accuracy of the matrix antenna plate 203 is improved.

[0031] As shown in the figure, Figure 9 The first adjusting assembly comprises: a second servo motor 401 fixedly connected to the gear ring 303; a rotating table 402 fixedly connected to an output shaft of the second servo motor 401; and a rotating disc 403 spline-connected to the driving ring 304, the rotating disc 403 being in transmission fit with the rotating table 402.

[0032] In the above scheme, the second servo motor 401 is externally provided with a shielding shell for preventing external dust and moisture from entering the interior to avoid damaging the electronic components inside, the rotating table 402 is a circular table structure, and the small-diameter end of the rotating table 402 is close to the center of the driving ring 304, the outer portions of the rotating table 402 and the rotating disc 403 are provided with rough materials, and the sliding resistance between the two is greater than the elastic force of the two elastic elements 207, to avoid the phenomenon of slipping of the rotating table 402 and the rotating disc 403.

[0033] When the staff turns on the antenna to receive external signals, the staff turns on the rotating platform of the rotating base 201 to make the rotating platform drive the support frame 202 to rotate (the self-rotation mode is to rotate 360° in the forward direction, and then rotate 360° in the reverse direction, and alternate rotation to prevent the internal communication cable from being wound), since the antenna is mostly placed in an open position or arranged at a high position to avoid the influence of obstacles on signal transmission, when the wind blows outside, the wind force will directly act on the matrix antenna plate 203, causing the connection between the support frame 202 and the rotating base 201 to be worn out for a long time, resulting in a gap between the two, reducing the signal receiving accuracy of the matrix antenna plate 203.

[0034] When the wind flow appears outside, the wind force detector will detect the direction and speed of the wind flow, after detecting the wind direction, the first servo motor 301 is turned on, the output shaft of the first servo motor 301 drives the second gear 302 to rotate, the second gear 302 drives the gear ring 303 to rotate, the gear ring 303 drives the driving ring 304 to rotate synchronously, so that the rotation axes of the driving ring 304 and the gear ring 303 are perpendicular to the wind direction, then the first servo motor 301 is turned off, then the second servo motor 401 is turned on, the output shaft of the second servo motor 401 drives the rotating table 402 to rotate by a certain angle according to the wind speed (i.e. the greater the external wind speed, the greater the rotating angle of the rotating table 402), the rotating table 402 drives the driving ring 304 to rotate by a certain angle through the rotating disc 403, then the second servo motor 401 is turned off, so that the driving ring 304 is in an inclined state and the high side is close to the wind direction, at this moment, the wind resistance preparation work is completed.

[0035] When the wind resistance preparation is completed, the rotating platform of the rotating base 201 is always in a rotating state, that is, the rotating platform of the rotating base 201 drives the two second elastic push rods 211 to rotate synchronously, and the abutting plates 212 on the telescopic ends of the two second elastic push rods 211 slide along the driving ring 304. Starting from the position of the matrix antenna plate 203 facing the wind direction, the maximum wind receiving area of the front surface of the matrix antenna plate 203, at this time, the driving ring 304 extrudes the abutting plate 212 above it, and the abutting plate 212 above it drives the telescopic end of the adjacent second elastic push rod 211 to slide outward, and the hydraulic oil in the fixed part of the second elastic push rod 211 enters the fixed part of the first elastic push rod 209 close to the opposite side of the matrix antenna plate 203 along the first flexible pipe, and the telescopic end of the first elastic push rod 209 drives the adjacent first rack 210 to move, and the first rack 210 drives the adjacent arc-shaped rack 205 to move along the adjacent counter-support shaft 206 through the adjacent first gear 208, so that the adjacent elastic element 207 is compressed, and the counteracting force of the elastic element 207 increases the support force of the adjacent counter-support shaft 206 to the support frame 202, so that the support force of the counter-support shaft 206 to the support frame 202 offsets the wind receiving force of the matrix antenna plate 203, and the abutting plate 212 below is separated from the driving ring 304, that is, according to the above steps, the counter-support shaft 206 on the front surface of the matrix antenna plate 203 does not exert a support force on the support frame 202, and during the process of rotating the rotating platform on the rotating base 201 by 90° in the clockwise or counterclockwise direction at this position, the wind receiving area of the front surface of the matrix antenna plate 203 gradually decreases, at this time, due to the inclined state of the driving ring 304, the upper abutting plate 212 is gradually reset under the action of the adjacent second elastic push rod 211, that is, the force of the counter-support shaft 206 on the opposite side of the matrix antenna plate 203 to the support frame 202 is synchronously reduced, so as to dynamically maintain the force balance of the support frame 202 in the wind environment, reduce the wear between the support frame 202 and the rotating base 201, and prolong the service life of the two, and for the same reason, when the opposite side of the matrix antenna plate 203 faces the wind direction, the driving ring 304 extrudes the abutting plate 212 below and separates from the abutting plate 212 above, so that the counter-support shaft 206 on the front surface of the matrix antenna plate 203 exerts a force on the support frame 202 to offset the force of the wind on the support frame 202, at this moment, the counter-support shaft 206 on the opposite side of the matrix antenna plate 203 does not exert a force on the support frame 202, and so on until the external wind disappears or decreases to have no effect on the support frame 202.

[0036] When the wind detector detects that the external wind flow is reduced to have no effect on the support frame 202, the second servo motor 401 is started, the output shaft of the second servo motor 401 drives the rotating table 402 to reset rotation, the rotating table 402 drives the driving ring 304 to reset rotation through the rotating disc 403, the horizontal state is restored, the extrusion on the two adhering plates 212 is released, that is, at this moment, the two counter supporting shafts 206 do not exert force on the support frame 202, when the external wind flow appears again, the above steps are repeated.

[0037] Example 3: on the basis of example 2, as shown in Figure 9 and Figure 10 The deflection assembly comprises: a third servo motor 501 fixedly connected to the rotating platform of the rotating base 201; a third gear 502 fixedly connected to the output shaft of the third servo motor 501; a fourth gear 503 fixedly connected to the support frame 202, the third gear 502 and the fourth gear 503 are engaged; and a second adjusting assembly arranged on the rotating platform of the rotating base 201, used for adjusting the abutting position of the rotating disc 403 and the rotating table 402.

[0038] In the above scheme, the third servo motor 501 and the rotating platform of the rotating base 201 are fixedly connected through high shear force bolts, which improves the stability of the power output of the third servo motor 501 and strengthens the fixing strength of the third servo motor 501, the third gear 502 and the fourth gear 503 are subjected to nitriding treatment, which improves the hardness and fatigue resistance of the two gears and prolongs the service life.

[0039] As shown in Figure 9 and Figure 10 The second adjusting assembly comprises: a third elastic push rod 504 fixedly connected to the rotating platform of the rotating base 201; a second rack 505 fixedly connected to the telescopic end of the third elastic push rod 504, the second rack 505 and the third gear 502 are engaged; a fourth elastic push rod 506 fixedly connected to the tooth ring 303, the telescopic end of the fourth elastic push rod 506 is limitingly and slidably connected with the rotating disc 403, the fixed part of the third elastic push rod 504 and the fixed part of the fourth elastic push rod 506 are fixedly connected and communicated with a second flexible pipe; and the inner diameter of the third elastic push rod 504 is smaller than the inner diameter of the fourth elastic push rod 506.

[0040] In the above scheme, the third elastic push rod 504, the fourth elastic push rod 506 and the inside of the second flexible pipe are filled with hydraulic oil, the second flexible pipe has a certain length allowance for adapting to the position change of the fourth elastic push rod 506, and the second flexible pipe has a self-adaptive winding device for keeping the second flexible pipe in a straight state to avoid winding on other parts and causing damage. By detecting the deflection angle of the support frame 202, the fitting position of the rotating disc 403 and the rotating table 402 is automatically changed, and the transmission ratio of the two is reduced, thereby reducing the deflection angle of the driving ring 304, ensuring the force balance of the support frame 202 under the wind environment, and prolonging the service life of the support frame 202. The inner diameter of the third elastic push rod 504 is smaller than the inner diameter of the fourth elastic push rod 506, which is used to reduce the sliding stroke of the fourth elastic push rod 506.

[0041] Because the antenna needs to tilt the matrix antenna board 203 by a certain angle to facilitate signal reception when receiving signals, the wind receiving area of the matrix antenna board 203 will decrease after deflection. When the support frame 202 needs to be deflected, the third servo motor 501 is started, the output shaft of the third servo motor 501 drives the fourth gear 503 to rotate through the third gear 502, so that the fourth gear 503 drives the support frame 202 to deflect to the required angle, and then the third servo motor 501 is turned off. In this process, the third gear 502 synchronously drives the second rack 505 to move, so that the second rack 505 drives the telescopic end of the third elastic push rod 504 to slide into its fixed part, the hydraulic oil in the fixed part of the third elastic push rod 504 enters the fixed part of the fourth elastic push rod 506 along the second flexible pipe, so that the telescopic end of the fourth elastic push rod 506 drives the rotating disc 403 to slide along the driving ring 304, changes the fitting position of the rotating disc 403 and the rotating table 402, reduces the transmission ratio of the rotating table 402 and the rotating disc 403, and then reduces the deflection angle of the driving ring 304. When the wind receiving area of the matrix antenna board 203 is reduced, the deflection angle of the driving ring 304 is reduced synchronously, which ensures the force balance of the support frame 202 under the wind environment and prolongs the service life of the support frame 202.
