Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a beam adjustment device and an antenna system. Background Art

[0002] Traditional electrically steerable antennas have a fixed vertical beamwidth. This limits their coverage area in special coverage scenarios, such as those near tall buildings. This necessitates the establishment of more sites, increasing construction costs. To increase the vertical beamwidth of electrically steerable antennas, a beam switching switch is incorporated into the phase shifter circuit to adjust the number of radiating elements connected to the RF circuit. However, existing beam switching switches have a complex structure, low switching reliability, and are prone to failure under complex operating conditions. Furthermore, the phase shifter's long travel requires significant space, making antenna miniaturization difficult. Summary of the Invention

[0038] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0039] In a first aspect, an embodiment of the present disclosure provides a beam adjustment device.

[0040] Figure 1 A schematic diagram of the structure of a beam adjustment device provided in an embodiment of the present disclosure is provided. Figure 2 A schematic structural diagram of a phase shifter provided in an embodiment of the present disclosure is shown. Figure 3 This is a schematic diagram of the structure of the main circuit board, antenna signal input terminal, and radiation unit in the embodiment of the present disclosure. Figure 1 、 Figure 2 and Figure 3, the beam adjustment device provided by the embodiment of the present disclosure includes:

[0041] Phase shifter 1, phase shifter 1 includes a main circuit board 11, a broken circuit board 12 and a dielectric plate 13. At least one circuit group is provided on the surface of the main circuit board 11, and the circuit group includes an input circuit 111 and multiple output circuits 112. The input circuit 111 is electrically connected to the antenna signal input terminal, and the output circuit 112 is electrically connected to the corresponding radiation units A1...An; the broken circuit board 12 and the dielectric plate 13 are both stacked with the main circuit board 11, and the broken circuit board 12 is rotatably connected to the main circuit board 11. The surface of the broken circuit board 12 is provided with a connecting circuit 121.

[0042] In some embodiments, each output line 112 is electrically connected to a group of radiation units A1...An. The embodiment of the present disclosure does not limit the number of radiation units in each group of radiation units. For example, each group of radiation units includes n radiation units, where n is an integer greater than or equal to 1. Each output line 112 corresponds to a port. Figure 3 There are four ports shown in FIG, namely the first output port P1, the second output port P2, the third output port P3 and the fourth output port P4. Figure 3 Two input ports IN1 and IN2 are shown.

[0043] In practical applications, the beam width can be adjusted by selecting the number of radiating elements connected to input line 111. For example, when input line 111 is connected to a larger number of output lines 112, input line 111 is connected to a larger number of radiating elements, i.e., more radiating elements are connected to the RF circuit, and the antenna system has a narrow beam state. When input line 111 is connected to a smaller number of output lines 112, input line 111 is connected to a smaller number of radiating elements, i.e., fewer radiating elements are connected to the RF circuit, and the antenna system has a wide beam state.

[0044] Transmission mechanism 2 is fixedly connected to dielectric plate 13. When transmission mechanism 2 pushes dielectric plate 13 to reciprocate, dielectric plate 13 squeezes fractured circuit board 12, causing it to rotate forward or reverse. When fractured circuit board 12 rotates to a first position, input line 111 is connected to output line 112; when fractured circuit board 12 rotates to a second position, input line 111 is disconnected from output line 112. The reciprocating motion of dielectric plate 13 pushes fractured circuit board 12 to rotate forward and reverse. Because the fractured circuit board 12 can connect and disconnect input line 111 and output line 112 with a relatively small rotation angle in both forward and reverse rotations, dielectric plate 13 only requires a relatively short stroke to connect and disconnect input line 111 and output line 112. Therefore, connection and disconnection of input line 111 and output line 112 can be achieved even in a confined space, contributing to the miniaturization and lightweight development of beam adjustment devices.

[0045] When the rupture circuit board 12 is rotated to the first position, the two ends of the connection line 121 on the rupture circuit board 12 are electrically connected to the input line 111 and the output line 112, respectively. That is, the input line 111 and the output line 112 are connected, so that the input line 111 is electrically connected to more radiating elements. In this case, the antenna system has a narrow beam state. When the rupture circuit board 12 is rotated to the second position, the connection line 121 on the rupture circuit board 12 is separated from the input line 111 and the output line 112. That is, the input line 111 and the output line 112 are disconnected, so that the input line 111 is electrically connected to fewer radiating elements. In this case, the antenna system has a wide beam state.

[0046] Figure 4 Schematic diagram of the phase shifter in the initial state in the beam adjustment device provided by the embodiment of the present disclosure. Figure 4 As shown, when the broken circuit board 12 is in the first position, the two ends of the connecting line 121 of the broken circuit board 12 are electrically connected to the input line IN and the output line, respectively. The connecting line now connects the input line and the output line. The antenna signal input IN is connected to the first output port P1 and the second output port P2. All radiating elements connected to the first output port P1 and the second output port P2 are connected to the RF circuit, and the antenna system is in a wide-beam state.

[0047] Figure 5 This is a schematic diagram of the phase shifter in the beam adjustment device provided by the embodiment of the present disclosure in the terminal state. Figure 5 As shown, in the second position, the broken circuit board forms a certain angle with the main circuit board, and the connecting wires of the broken circuit board are misaligned with the input and output circuits. The connecting wires of the broken circuit board are not electrically connected to the input and output circuits, and the input and output circuits are no longer connected. The first output port P1 is connected to the antenna signal input terminal IN, but the second output port P2 is disconnected from the antenna signal input terminal IN. At this time, the radiating element corresponding to the second output port P2 is not connected to the RF circuit, and the antenna system is in a narrow beam state.

[0048] A beam adjustment device provided by an embodiment of the present disclosure includes at least one circuit group disposed on the surface of a main circuit board. Each circuit group includes an input circuit and multiple output circuits. The input circuit is electrically connected to an antenna signal input terminal, and the output circuit is electrically connected to a corresponding radiating element. A breakable circuit board and a dielectric plate are both stacked on the surface of the main circuit board. The breakable circuit board is rotatably connected to the main circuit board. Connecting circuits are disposed on the surface of the breakable circuit board. A transmission mechanism is fixedly connected to the dielectric plate. When the transmission mechanism propels the dielectric plate back and forth, the dielectric plate squeezes the breakable circuit board to achieve forward and reverse rotation. When the breakable circuit board rotates to a first position, the connecting circuits on the surface of the breakable circuit board connect the input circuit and the output circuit. When the breakable circuit board rotates to a second position, the connecting circuits on the surface of the breakable circuit board separate from the input circuit and the output circuit, thereby disconnecting the input circuit and the output circuit. In other words, the input and output circuits can be switched on and off by the forward and reverse rotation of the breakable circuit board. No additional components are required, the structure is simple, and precise switching control is not required, thereby improving switching reliability. No additional space is required, and this contributes to the miniaturization of the beam adjustment device. Furthermore, due to its simple structure, it is less likely to fail under complex operating conditions.

[0049] It should be noted that, for ease of description, in the embodiment of the present disclosure, the first direction X is the length direction of the main circuit board, the second direction Y is the width direction of the main circuit board, and the third direction Z is the thickness direction of the main circuit board.

[0050] The embodiments of the present disclosure provide dielectric plates with various structures to promote the rotation of a broken circuit board.

[0051] like Figure 2 As shown, the broken circuit board 12 and the dielectric plate 13 are spaced apart in the width direction (second direction Y) of the main circuit board. The dielectric plate 13 includes a dielectric plate body 131 and a protrusion 132. The protrusion 132 is located on the side of the dielectric plate body 131 near the broken circuit board 12. When the dielectric plate 13 reciprocates in the first direction X, the protrusion 132 squeezes the broken circuit board 12 to rotate. In some embodiments, a groove 138 is formed at the junction of the protrusion 132 and the dielectric plate body 131. The sidewalls of the groove 138 are curved, which facilitates the dielectric plate 13 to push the broken circuit board 12 to rotate.

[0052] like Figure 4 As shown, in the initial state, the protrusion 132 of the dielectric plate 13 is located on the right side of the broken circuit board 12, that is, the dielectric plate 13 is located at the initial position I, the broken circuit board 12 is located at the first position, and the connecting line 121 on the broken circuit board 12 is electrically connected to the input line 111 and the output line 112. At this time, the input line 111 and the output line 112 are electrically connected, and the input line IN is connected to the first output port P1 and the second output port P2.

[0053] like Figure 6As shown, when the dielectric plate 13 moves to the left until the protrusion 132 just touches the broken circuit board 12, that is, when the dielectric plate 13 moves to the middle position II, the dielectric plate 13 has not yet pushed the broken circuit board 12 to rotate, and the connecting line 121 on the broken circuit board 12 is electrically connected to the input line 111 and the output line 112. At this time, the input line 111 and the output line 112 are electrically connected, and the input line IN is connected to the first output port P1 and the second output port P2.

[0054] like Figure 5 As shown, when the dielectric plate 13 continues to move to the left, the protrusion 132 on the dielectric plate 13 pushes the broken circuit board 12 to rotate. When the dielectric plate 13 moves to the end position III, the broken circuit board 12 rotates to the second position. The connecting line 121 on the broken circuit board 12 is disconnected from the input line 111 and the output line 112. The input line 111 and the output line 112 are disconnected. The input line IN is still connected to the first output port P1, but is disconnected from the second output port P2.

[0055] In the embodiments of the present disclosure, the protrusion can adopt a variety of structures, and two structures are mainly introduced below.

[0056] Combine Figure 2 and Figure 5 The convex portion 132 is tilted toward the broken circuit board 12 , and the joint position of the convex portion 132 and the dielectric plate body 131 forms an arc surface, which helps to reduce the resistance of the broken circuit board 12 when it rotates.

[0057] In the embodiment of the present disclosure, the inclined arrangement of the protrusion 132 can not only realize the function of the dielectric plate 13 pushing the broken circuit board 12 to reciprocate, but also reduce the total width of the dielectric plate 13, that is, the length in the second direction.

[0058] In some embodiments, the protrusion 132 is inclined toward the broken circuit board 12 , which can reduce the length of the protrusion 132 in the first direction, making the design of the dielectric plate 13 lighter and facilitating the miniaturization of the beam adjustment device.

[0059] Figure 7 This is a schematic diagram of the structure of another phase shifter provided in an embodiment of the present disclosure. Figure 7 As shown, the surface of the convex portion 132 facing the broken circuit board 12 is an arc surface; a concave portion 133 is provided on the dielectric plate body 131, and the concave portion 133 is adjacent to the convex portion 132, and the inner side surface of the concave portion 133 is an arc surface, and smoothly transitions to the arc surface of the convex portion 132. This can reduce the width of the dielectric plate 13, make the design of the dielectric plate 13 lighter, and contribute to the miniaturization of the beam adjustment device.

[0060] In some embodiments, the broken circuit board 12 is axially connected to the main circuit board 11 , and the broken circuit board 12 rotates relative to the main circuit board 11 via a rotating shaft.

[0061] like Figure 2 As shown, a through hole 122 is provided on the broken circuit board 12 and passes through the thickness thereof, and a fixing hole 113 is provided on the main circuit board 11 and passes through the thickness thereof.

[0062] The phase shifter 1 further includes a shaft connection assembly, which shaft connects the broken circuit board 12 to the main circuit board 11 via the through hole 122 and the fixing hole 113 .

[0063] In some embodiments, the shaft connection assembly includes a clamping spring arm 41 and a locking plate 42, wherein the clamping spring arm 41 includes a spring arm cap 411 and a connecting shaft 412, the fixed end of the connecting shaft 412 is fixed to the surface of the spring arm cap 411, the free end of the connecting shaft 412 passes through the through hole 122 and the fixing hole 113 and part of the connecting shaft 412 extends out; the locking plate 42 is provided with a locking hole 421 that passes through its thickness, and the locking hole 421 is connected to the protruding part of the connecting shaft 412.

[0064] In the disclosed embodiment, the ruptured circuit board not only needs to rotate relative to the main circuit board to connect and disconnect the input and output circuits, but also needs to ensure reliable connection when the input and output circuits are connected. The compression spring arm and locking plate can improve the reliability of the connection when the ruptured circuit connects the input and output circuits.

[0065] In an embodiment of the present disclosure, a dielectric plate of another structure is also provided. Figure 8 As shown, the dielectric plate 13 includes a dielectric plate body 131, a first groove 134 and a second groove 135. The first groove 134 and the second groove 135 are arranged on the surface of the dielectric plate body 131 close to the main circuit board 11 and are located on the first side of the dielectric plate body 131. The first groove 134 and the second groove 135 are connected, and the first groove 134 extends along the length direction of the dielectric plate body 131. The second groove 135 extends obliquely toward the second side of the dielectric plate body 131. The connection position of the first groove 134 and the second groove 135 has a smooth transition; the broken circuit board 12 is embedded in the first groove 134 and the second groove 135. When the broken circuit board 12 rotates, the inner wall of the second groove 135 squeezes the broken circuit board 12.

[0066] It should be noted that the first side and the second side of the dielectric plate body 131 are two opposite sides of the dielectric plate body 131 in the second direction. In this embodiment, the first side is Figure 8 The first side is closer to the reader, and the second side is farther away from the reader.

[0067] In some embodiments, a fixing hole 113 extending through the thickness of the main circuit board 11 is provided. A latch 123 is provided on the broken circuit board 12. The latch 123 and the connecting line 121 are located on the same side of the broken circuit board 12. The latch 123 engages with the fixing hole 113 to secure the broken circuit board 12 to the main circuit board 11.

[0068] like Figure 2 、 Figure 7 and Figure 8 As shown, the side surface of the broken circuit board 12 is an arc surface. When the broken circuit board rotates, the arc surface contacts the dielectric plate 13, which can reduce the resistance to the rotation of the broken circuit board 12 and make the rotation process of the broken circuit board 12 smoother.

[0069] In some embodiments, at least one circuit group is spaced apart in the length direction of the main circuit board 11. Figure 2 As shown, the phase shifter includes two line groups, and the two line groups are spaced apart in the first direction.

[0070] In some embodiments, the plurality of output lines 112 in the line group are spaced apart in the length direction of the main circuit board 11. Figure 2 As shown, each line group includes two output lines 112 , and the two output lines 112 are spaced apart in the first direction.

[0071] In some embodiments, the input circuit 111 and the output circuit 112 are spaced apart in the width direction of the main circuit board 11. Figure 2 As shown, the input line 111 and the output line 112 are spaced apart in the second direction.

[0072] In order to improve the stability of the reciprocating motion of the dielectric plate, a guide groove 114 is provided on the main circuit board 11, and a guide column 136 is provided on the dielectric plate 13. The guide column 136 is embedded in the guide groove 114, and the dielectric plate 13 reciprocates under the guidance of the guide column 136 and the guide groove 114.

[0073] In some embodiments, the guide slot 114 is an elongated slot extending along the length of the main circuit board 11. The length of the guide slot 114 limits the travel of the dielectric plate 13. The distance that the guide post 136 moves from the first end to the second end of the guide slot 114 is the travel of the dielectric plate 13. The travel of the dielectric plate 13 determines the rotation angle of the fractured circuit board 12. As the dielectric plate 13 reciprocates, the guide post 136 reciprocates between the first and second ends of the guide slot 114.

[0074] In the embodiment of the present disclosure, the transmission mechanism is the power source for the phase shifter to adjust the phase, that is, the transmission mechanism is the power source for pushing the medium plate 13 to move back and forth.

[0075] Figure 9 This is an exploded schematic diagram of a transmission mechanism provided in an embodiment of the present disclosure. Figure 10 A schematic diagram of a transmission mechanism according to an embodiment of the present disclosure is shown. Figure 11 Schematic diagram of the transmission mechanism provided in the embodiment of the present disclosure at another angle. Figure 1 、 Figures 9 to 11 As shown, the transmission mechanism 2 includes a pull rod 21, at least one adapter plate 22, a rack 23, a gear 24, a drive device 25 and a split converter 26, wherein at least one adapter plate 22 is fixed to the pull rod 21 at intervals, and the adapter plate 22 is fixedly connected to the corresponding medium plate 13; the rack 23 is fixedly connected to the pull rod 21, and the length direction of the rack 23 is consistent with the length direction of the pull rod 21; the gear 24 is engaged with the rack 23, and the rotation of the gear 24 drives the rack 23 to move linearly; the drive device 25 is used to provide power for reciprocating motion; one end of the split converter 26 is fixedly connected to the output end of the drive device 25, and the other end is fixedly connected to the gear 24. The split converter 26 converts the power output by the drive device 25 into power for the rotation of the gear 24.

[0076] The structure of the tie rod 21 is not limited in the embodiment of the present disclosure. For example, the tie rod 21 includes a first tie rod 211 and a second tie rod 212. The first tie rod 211 and the second tie rod 212 are arranged in parallel and fixed together by a connecting rod 213. In order to improve the stability of the fixing of the first tie rod 211 and the second tie rod 212, a plurality of connecting rods 213 can be arranged between the first tie rod 211 and the second tie rod 212.

[0077] In the embodiment of the present disclosure, the adapter plate 22 is used to transfer the movement force of the pull rod 21 to the medium plate. When the adapter plate 22 reciprocates with the pull rod 21 in the first direction, the reciprocating force is transferred to the medium plate, so that the medium plate reciprocates with the pull rod 21.

[0078] In the disclosed embodiment, rack 23 is fixedly connected to pull rod 21, for example, by being fixed to connecting rod 213. Gear 24 includes a spur gear portion 241 and a helical gear portion 242, located at either end of gear 24. Spur gear portion 241 meshes with rack 23, while helical gear portion 242 is connected to a split converter 26, which is connected to the rotating shaft of drive device 25. Driven by drive device 25, gear 24 rotates, driving rack 23 in linear motion. When drive device 25 alternates between forward and reverse rotation, pull rod 21 reciprocates in a first direction.

[0079] In some embodiments, as Figure 1 As shown, the pull rod 21 is fixed to the outside of the reflector 3 of the antenna system, and the phase shifter is arranged on the inside of the reflector 3.

[0080] In some embodiments, as Figure 9 and Figure 10 As shown, the split converter 26 includes a bevel gear 261 and a steering mechanism 263, wherein the bevel gear 261 is fixedly connected to the gear 24, the bevel gear 261 is plugged into the bevel tooth portion of the gear 24, the input end of the steering mechanism 263 is fixedly connected to the output end of the drive device 25, the output end of the steering mechanism 263 is fixedly connected to the bevel gear 261, and the input end and the output end of the steering mechanism 263 are perpendicular to each other, so that the power output by the drive device 25 can be turned 90 degrees, thereby improving the flexibility of the setting of the drive device 25.

[0081] In some embodiments, the transmission mechanism 2 further includes an upper cover 264 and a lower cover 265.

[0088] In order to better understand the beam adjustment device provided by the embodiment of the present disclosure, the working process of the beam adjustment device provided by the embodiment of the present disclosure is further introduced below.

[0089] like Figure 4 As shown, when the dielectric plate 13 is in the initial position I, the broken circuit board 12 is in the first position, and the connecting line 121 on the broken circuit board 12 is electrically connected to the input line 111 and the output line 112. At this time, the input line IN is connected to the first output port P1 and the second output port P2, and all the radiation units connected to the first output port P1 and the second output port P2 are connected to the radio frequency circuit, and the antenna system is in a wide beam state.

[0090] like Figure 6 As shown, when the driving device rotates forward and causes the dielectric plate 13 to move to the middle position II, the area of ​​the output line 112 covered by the dielectric plate 13 changes, and the phase of the electromagnetic wave reaching the first output port P1 and the second output port P2 changes (phase shift is achieved), but the broken circuit board 12 is still in the first position, and the connecting line 121 on the broken circuit board 12 is electrically connected to the input line 111 and the output line 112. At this time, the input line IN is connected to the first output port P1 and the second output port P2, and all the radiating units connected to the first output port P1 and the second output port P2 are connected to the radio frequency circuit, and the antenna system is in a wide beam state.

[0091] When the driving device continues to rotate forward, the medium plate 13 moves to the left, and the medium plate 13 pushes the broken circuit board 12 to rotate counterclockwise. Figure 5 As shown, when the dielectric plate 13 moves to the end position III, the broken circuit board 12 is located in the second position, and the connecting line 121 on the broken circuit board 12 is disconnected from the input line 111 and the output line 112.

[0092] When the driving device rotates in the reverse direction, the medium plate 13 moves to the right, and the medium plate 13 pushes the broken circuit board 12 to rotate clockwise. When the medium plate 13 is in the middle position, as shown in FIG. Figure 6As shown, the broken circuit board 12 is located in the first position, and the broken circuit board 12 electrically connects the connecting line 121 on the broken circuit board 12 with the input line 111 and the output line 112 again.

[0093] As the drive mechanism continues to rotate in the opposite direction, dielectric plate 13 continues to move rightward. Broken circuit board 12 remains in the first position, but the area of ​​output line 112 covered by dielectric plate 13 changes, shifting the phase of the electromagnetic waves reaching first output port P1 and second output port P2. When dielectric plate 13 returns to initial position I, connection line 121 on broken circuit board 12 is electrically connected to input line 111 and output line 112.

The input line IN is disconnected from the second output port P2, and the radiating unit connected to the second output port P2 is not connected to the radio frequency circuit. The antenna system is in a narrow beam state.

[0096] When the drive mechanism drives dielectric plate 13 to the right, dielectric plate 13 pushes broken circuit board 12 to rotate clockwise. When broken circuit board 12 returns to the first position, connection line 121 on broken circuit board 12 is electrically connected to input line 111 and output line 112 again. Input line IN communicates with first output port P1 and second output port P2.

Figure 15 As shown, when the broken circuit board 12 is in the second position, the connecting line 121 on the broken circuit board 12 is disconnected from the input line 111 and the output line 112. At this time, the input line IN is connected to the first output port P1, and the radiating unit connected to the first output port P1 is connected to the radio frequency circuit. The input line IN is disconnected from the second output port P2, and the radiating unit connected to the second output port P2 is not connected to the radio frequency circuit.
