Description

Technical Field

[0002] The vertical beam width of a traditional electrically tunable antenna is fixed. In special coverage scenarios such as when there are high-rise buildings at a site, the coverage area of the electrically tunable antenna is limited by the vertical beam width, and more sites need to be established, increasing the site construction cost. To increase the vertical beam width of the electrically tunable antenna, a beam switching switch is set on the phase shifter circuit to change the number of radiation units connected to the radio frequency circuit. However, the current beam switching switch has a complex structure, low reliability during the switching process, is prone to failure when facing complex working conditions, and moreover, the stroke of the phase shifter is long, occupying a large space, making it difficult to miniaturize the antenna.

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

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

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

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

[0042] In some embodiments, each output line 112 is electrically connected to a set of radiation units A1... An. The embodiments of the present disclosure do not limit the number of radiation units in each set of radiation units. For example, each set 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. In Figure 3 a total of four ports are shown, namely the first output port P1, the second output port P2, the third output port P3, and the fourth output port P4. In Figure 3 a total of two input ports IN1 and IN2 are shown.

[0043] In practical applications, the number of radiation units connected to the input line 111 can be selected to adjust the beam width. For example, when the input line 111 is connected to more output lines 112, the number of radiation units connected to the input line 111 is larger, that is, more radiation units are connected to the radio frequency circuit, and the antenna system has a narrow beam state. When the input line 111 is connected to a smaller number of output lines 112, the number of radiation units connected to the input line 111 is smaller, that is, fewer radiation units are connected to the radio frequency circuit, and the antenna system has a wide beam state.

[0044] A transmission mechanism 2, which is fixedly connected to the dielectric board 13. When the transmission mechanism 2 pushes the dielectric board 13 to reciprocate, the dielectric board 13 squeezes the broken circuit board 12 to rotate forward or backward. When the broken circuit board 12 rotates to the first position, the input line 111 is connected to the output line 112; when the broken circuit board 12 rotates to the second position, the input line 111 is disconnected from the output line 112. The reciprocating motion of the dielectric board 13 pushes the broken circuit board 12 to rotate forward and backward. Since the rotation angle of the broken circuit board 12 for forward and backward rotation is small to achieve the on / off of the input line 111 and the output line 112, therefore, the dielectric board 13 only needs a short stroke to achieve the on / off of the input line 111 and the output line 112. Therefore, the on / off of the input line 111 and the output line 112 can be achieved in a small space, which helps the beam adjustment device to develop towards miniaturization and light weight.

[0045] When the broken circuit board 12 rotates to the first position, both ends of the connection line 121 on the broken circuit board 12 are electrically connected to the input line 111 and the output line 112 respectively, that is, the input line 111 is connected to the output line 112, so that the input line 111 is electrically connected to more radiation units. At this time, the antenna system has a narrow beam state. When the broken circuit board 12 rotates to the second position, the connection line 121 on the broken circuit board 12 is separated from the input line 111 and the output line 112, that is, the input line 111 is disconnected from the output line 112, so that the input line 111 is electrically connected to fewer radiation units. At this time, the antenna system has a wide beam state.

[0046] Figure 4 This is a schematic diagram of the phase shifter in the initial state of the beam adjustment device provided by the embodiment of the present disclosure. As Figure 4 shown, when the broken circuit board 12 is in the first position, both ends of the connection line 121 of the broken circuit board 12 are electrically connected to the input line IN and the output line respectively. At this time, the connection line connects the input line and the output line. The antenna signal input terminal 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.

[0047] Figure 5 This is a schematic diagram of the phase shifter in the termination state of the beam adjustment device provided by the embodiment of the present disclosure. As Figure 5 shown, in the second position, the broken circuit board forms a certain angle with the main circuit board, the connection line of the broken circuit board is misaligned with the input line and the output line, and the connection line of the broken circuit board is not electrically connected to the input line and the output line. At this time, the input line and the output line 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 radiation unit corresponding to the second output port P2 is not connected to the radio frequency circuit, and the antenna system is in a narrow beam state.

[0048] The beam adjustment device provided by the embodiments of the present disclosure is provided with at least one set of circuit groups on the surface of the main circuit board. Each circuit group includes an input circuit and a plurality of output circuits. The input circuit is electrically connected to the antenna signal input end, and the output circuit is electrically connected to the corresponding radiation unit. The broken circuit board and the dielectric board are both stacked on the surface of the main circuit board. The broken circuit board is rotatably connected to the main circuit board. A connection circuit is provided on the surface of the broken circuit board. The transmission mechanism is fixedly connected to the dielectric board. When the transmission mechanism pushes the dielectric board to reciprocate, the dielectric board squeezes the broken circuit board to achieve forward and reverse rotation. When the broken circuit board rotates to the first position, the connection circuit on the surface of the broken circuit board connects the input circuit and the output circuit; when the broken circuit board rotates to the second position, the connection circuit on the surface of the broken circuit board separates from the input circuit and the output circuit, thereby disconnecting the input circuit and the output circuit. That is, the on-off of the input circuit and the output circuit can be realized by the forward and reverse rotation of the broken circuit board, without the need to additionally increase components, the structure is simple, and the on-off does not require precise control, thereby improving the reliability of switching, and does not require additional space, which helps to miniaturize the beam adjustment device. In addition, due to the simple structure, it is not easy to fail under complex working conditions.

[0049] It should be noted that, for the convenience of description, in the embodiments 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 boards with various structures to realize the rotation of the broken circuit board.

[0051] As Figure 2 shown, the broken circuit board 12 and the dielectric board 13 are arranged at intervals in the width direction (the second direction Y) of the main circuit board. The dielectric board 13 includes a dielectric board body 131 and a convex portion 132. The convex portion 132 is provided on the side of the dielectric board body 131 close to the broken circuit board 12. When the dielectric board 13 reciprocates in the first direction X, the convex portion 132 squeezes the broken circuit board 12 to rotate. In some embodiments, a groove 138 is formed at the joint position of the convex portion 132 and the dielectric board body 131. The side wall of the groove 138 is arc-shaped, which is beneficial to the dielectric board 13 to push the broken circuit board 12 to rotate.

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

[0053] As Figure 6As shown, when the dielectric plate 13 moves leftward until the convex portion 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. The connection 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] As Figure 5 shown, when the dielectric plate 13 continues to move leftward, the convex portion 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, at this time the broken circuit board 12 rotates to the second position, the connection 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, and 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 convex portion can adopt various structures. Two structures will be mainly introduced below.

[0056] Combined with Figure 2 and Figure 5 , the convex portion 132 is inclined 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. Setting it as an arc surface helps to reduce the resistance when the broken circuit board 12 rotates.

[0057] In the embodiments of the present disclosure, the inclined setting of the convex portion 132 can not only realize the function of the dielectric plate 13 pushing the broken circuit board 12 to move back and forth, but also reduce the total width of the dielectric plate 13, that is, the length in the second direction.

[0058] In some embodiments, the convex portion 132 is inclined toward the broken circuit board 12, which can reduce the length of the convex portion 132 in the first direction, make the design of the dielectric plate 13 more lightweight, and contribute to the miniaturization of the beam adjustment device.

[0059] Figure 7 is a schematic structural diagram of another phase shifter provided by the embodiments of the present disclosure. As Figure 7 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. The inner side surface of the concave portion 133 is an arc surface and is smoothly transitioned with the arc surface of the convex portion 132, which can reduce the width of the dielectric plate 13, make the design of the dielectric plate 13 more lightweight, and contribute to the miniaturization of the beam adjustment device.

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

[0061] As shown Figure 2 in the figure, through holes 122 penetrating through the thickness of the fractured circuit board 12 are provided on the fractured circuit board 12, and fixing holes 113 penetrating through the thickness of the main circuit board 11 are provided on the main circuit board 11.

[0062] The phase shifter 1 further includes a shaft connection assembly. The shaft connection assembly shaft-connects the fractured circuit board 12 to the main circuit board 11 by means of the through holes 122 and the fixing holes 113.

[0063] In some embodiments, the shaft connection assembly includes a pressing spring arm 41 and a locking piece 42. Among them, the pressing 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 a part of the connecting shaft 412 extends out; the locking piece 42 is provided with a locking hole 421 penetrating through its thickness, and the locking hole 421 is connected to the extending part of the connecting shaft 412.

[0064] In the embodiments of the present disclosure, the fractured circuit board not only needs to rotate relative to the main circuit board to realize the on-off of the input line and the output line, but also needs to ensure reliable connection when the input line and the output line are connected. The pressing spring arm and the locking piece can improve the reliability of the connection when the fractured circuit connects the input line and the output line.

[0065] In the embodiments of the present disclosure, a dielectric plate with another structure is also provided. Figure 8 As shown in the figure, 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 provided on the surface of the dielectric plate body 131 close to the main circuit board 11 and on the first side of the dielectric plate body 131. The first groove 134 and the second groove 135 communicate with each other, and the first groove 134 extends along the length direction of the dielectric plate body 131. The second groove 135 extends obliquely towards the second side of the dielectric plate body 131. The connection position of the first groove 134 and the second groove 135 is smoothly transitioned; the fractured circuit board 12 is embedded in the first groove 134 and the second groove 135. When the fractured circuit board 12 rotates, the inner wall of the second groove 135 presses against the fractured 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 side close to the reader, and the second side is the side far from the reader.

[0067] In some embodiments, fixing holes 113 penetrating the thickness of the main circuit board 11 are provided on the main circuit board 11. A latch 123 is provided on the broken circuit board 12. The latch 123 and the connection line 121 are on the same side of the broken circuit board 12. The latch 123 is snapped into the fixing hole 113 to fix the broken circuit board 12 to the main circuit board 11.

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

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

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

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

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

[0073] In some embodiments, the guide groove 114 is a long strip-shaped groove and extends along the length direction of the main circuit board 11. The length of the guide groove 114 can limit the stroke of the dielectric plate 13. The distance that the guide post 136 moves from the first end to the second end of the guide groove 114 is the stroke of the dielectric plate 13. The stroke of the dielectric plate 13 determines the rotation angle of the broken circuit board 12. When the dielectric plate 13 reciprocates, the guide post 136 reciprocates between the first end and the second end of the guide groove 114.

[0074] In the embodiments of the present disclosure, the transmission mechanism is the power source for the phase shifter to perform phase adjustment, that is, the transmission mechanism is the power source for pushing the dielectric plate 13 to reciprocate.

[0075] Figure 9 Exploded view of a transmission mechanism provided by an embodiment of the present disclosure Figure 10 Structural diagram of a transmission mechanism provided by an embodiment of the present disclosure Figure 11 Schematic diagram of the transmission mechanism provided by an embodiment of the present disclosure from another angle. As Figure 1 、 Figures 9 to 11 shown, the transmission mechanism 2 includes a pull rod 21, at least one adapter plate 22, a rack 23, a gear 24, a driving device 25 and a split converter 26. Among them, at least one adapter plate 22 is fixedly arranged at intervals on the pull rod 21, and the adapter plate 22 is fixedly connected to the corresponding dielectric plate 13; the rack 23 is fixedly connected to the pull rod 21, and the length direction of the rack 23 is the same as the length direction of the pull rod 21; the gear 24 meshes with the rack 23, and the rotation of the gear 24 drives the linear movement of the rack 23; the driving device 25 is used to provide the power for reciprocating motion; one end of the split converter 26 is fixedly connected to the output end of the driving device 25, and the other end is fixedly connected to the gear 24. The split converter 26 converts the power output by the driving device 25 into the power for the rotation of the gear 24.

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

[0077] In the embodiment of the present disclosure, the adapter plate 22 is used to transmit the moving force of the pull rod 21 to the dielectric plate. When the adapter plate 22 reciprocates in the first direction along with the pull rod 21, it transmits the reciprocating acting force to the dielectric plate, so that the dielectric plate reciprocates along with the pull rod 21.

[0078] In the embodiment of the present disclosure, the rack 23 is fixedly connected to the pull rod 21. For example, the rack 23 is fixed on the connecting rod 213. The gear 24 includes a straight tooth part 241 and a helical tooth part 242. The straight tooth part 241 and the helical tooth part 242 are respectively located at both ends of the gear 24. The straight tooth part 241 meshes with the rack 23, and the helical tooth part 242 is connected to the split converter 26. The split converter 26 is connected to the rotating shaft of the driving device 25. The gear 24 rotates under the drive of the driving device 25 and drives the rack 23 to perform linear motion. When the driving device 25 rotates forward and reverses alternately, the pull rod 21 reciprocates in the first direction.

[0088] To better understand the beam adjustment device provided by the embodiments of the present disclosure, the working process of the beam adjustment device provided by the embodiments of the present disclosure will be further introduced below.

[0089] As Figure 4 shown, when the dielectric plate 13 is in the initial position I, the broken circuit board 12 is located at the first position, and the connection 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] As Figure 6 shown, when the driving device rotates forward so that the dielectric plate 13 moves to the intermediate position II, since the area of the output line 112 covered by the dielectric plate 13 changes, 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 located at the first position, and the connection 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.

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

When the dielectric plate 13 is in the intermediate position, as Figure 6As shown, the broken circuit board 12 is located at the first position.

[0093] When the driving device continues to rotate in the reverse direction, the dielectric plate 13 continues to move to the right. The broken circuit board 12 remains at the first position, but 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. When the dielectric plate 13 moves to the initial position Ⅰ, the connection line 121 on the broken circuit board 12 electrically connects to the input line 111 and the output line 112.

[0095] When the driving device drives the dielectric plate 13 to move to the left, the dielectric plate 13 pushes the broken circuit board 12 to rotate counterclockwise. As Figure 13 shown, when the broken circuit board 12 is located at the second position, the connection line 121 on the broken circuit board 12 disconnects 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 radiation 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 radiation 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 driving device drives the dielectric plate 13 to move to the right, the dielectric plate 13 pushes the broken circuit board 12 to rotate clockwise.

As Figure 15 shown, when the broken circuit board 12 is in the second position, the connection 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 communicated with the first output port P1, the radiation 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 radiation unit connected to the second output port P2 is not connected to the radio frequency circuit, and the antenna system is in a narrow beam state.
