The gearshift adjustment device 1 and the base station antenna provided by the present invention will be described below with reference to fig. 1 to 10.
The antenna transmission device aims at solving the problems that the transmission of the antenna transmission device in the traditional technology is complex, the occupied area is large, and the cost is high. The invention provides a gear shifting adjusting device 1 and a base station antenna, and the main invention point of the invention is the gear shifting adjusting device 1, so that the related structure of the base station antenna is not described again.
The invention provides a gear shifting adjusting device 1, which comprises a mounting seat 2, wherein a mounting cavity 6 is arranged in the mounting seat 2; the gear shifting transmission unit 3 comprises at least one gear shifting transmission part 9 arranged in the mounting cavity 6, the gear shifting transmission part 9 is provided with a plurality of gear output pieces 13, and one gear output piece 13 is used for corresponding to one antenna gear; the gear shifting unit 4 comprises a position selecting driving part 10 arranged in the mounting cavity 6 and a position selecting part 11 arranged corresponding to the gear shifting transmission part 9, and the position selecting driving part 10 is in driving connection with the position selecting part 11 so that the position selecting part 11 selects a gear output piece 13 in the corresponding gear shifting transmission part 9; and a shift drive unit 5 including a shift drive portion 12 provided on the mounting base 2 and corresponding to the shift transmission portion 9, the shift drive portion 12 being configured to drive the corresponding select portion 11 to drive the corresponding shift position output member 13.
It should be noted that the shift adjustment device 1 according to the first embodiment of the present invention has one shift transmission portion 9, and the shift adjustment devices 1 according to the second and third embodiments have two (a plurality of) shift transmission portions 9. Each gear shifting transmission part 9 can correspond to a plurality of antenna gears, so that the number of the antenna gears corresponding to the gear shifting transmission parts 9 is more; on the basis, the invention is provided with the position selecting part 11 corresponding to the gear shifting transmission part 9, and each position selecting part 11 can select the antenna gear in the corresponding gear shifting transmission part 9. In the technical scheme provided by the present invention, one bit selection driving portion 10 drives one bit selection portion 11, which may be the first bit selection portion 11 or the last bit selection portion 11, so that each bit selection portion 11 corresponds to one antenna gear under the linkage action; in this case, since the shift control device 1 according to the present invention includes the plurality of shift driving portions 12 corresponding to the selection portion 11, when a certain antenna shift position needs to be selected, the corresponding shift driving portion 12 may be driven.
The gear shifting adjusting device 1 provided by the invention has a compact structure, can selectively output multiple groups of power by adopting one position selecting driving part 10 through the cooperative work of the gear shifting transmission unit 3, the gear shifting switching unit 4 and the gear shifting driving unit 5, occupies small space, is beneficial to the miniaturization and the light weight of a multi-frequency fusion antenna, is more beneficial to reducing the cost and improving the working efficiency of the gear shifting adjusting device 1.
Specifically, the gear shifting transmission part 9 includes a transmission shaft 14 disposed in the mounting cavity 6 and a plurality of transmission gears 15 disposed on the transmission shaft 14, as shown in fig. 2-3, the transmission shaft 14 extends along the length direction of the mounting base 2, the transmission gears 15 are sequentially disposed at intervals along the length direction of the mounting base 2, each transmission gear 15 has a movable stroke rotating along the axial direction, and each transmission gear 15 is respectively connected to one gear output member 13 in a driving manner; the position selecting part 11 comprises at least one position selecting gear 19, the position selecting driving part 10 is in driving connection with the position selecting gear 19, so that the position selecting gear 19 has a movable stroke moving along the axial direction of the transmission shaft 14 of the corresponding gear shifting transmission part 9, and in the process of moving the position selecting gear 19, the position selecting gear 19 is meshed with the plurality of transmission gears 15 on the corresponding transmission shaft 14 in sequence so as to correspondingly select the antenna gear.
As mentioned above, at least one position selecting gear 19 is provided, and one position selecting gear 19 is the simplest case, and the position selecting gear 19 only needs to be meshed with each transmission gear 15 in sequence, but this arrangement is more suitable for the case where the number of the transmission gears 15 on one transmission shaft 14 is low, for example, when only 3 or 4 transmission gears 15 are provided on one transmission shaft 14, the length of the transmission shaft 14 is controllable, and one position selecting gear 19 can also meet the driving requirement; however, if more than 5 transmission gears 15 are disposed on one transmission shaft 14, for example, 8 or 10 transmission gears 15, the length of the transmission shaft 14 is long, and thus the movement path of the positioning selection gear 19 is long, which is not favorable for the driving of the positioning selection gear 19 and the simplification of the driving source. Therefore, when the number of the transmission gears 15 is large, that is, when the number of the antenna stages corresponding to one shift transmission portion 9 is large, a plurality of selector gears 19 may be provided in one selector portion 11, such that each selector gear 19 corresponds to a plurality of stage output members 13. Therefore, in the technical solution provided by the present invention, the selecting portion 11 includes two selecting gears 19, one selecting gear 19 corresponds to a part of the gear output members 13 in one shift transmission portion 9, the other selecting gear 19 corresponds to the rest of the gear output members 13 in the shift transmission portion 9, and when one selecting gear 19 is engaged with one of the transmission gears 15, the other selecting gear 19 is located between the other two transmission gears 15. Referring to fig. 3, taking the first embodiment as an example, 8 transmission gears 15 are arranged on one transmission shaft 14, in an initial state, one position selecting gear 19 is arranged in parallel with the first transmission gear 15, and the other position selecting gear 19 is arranged between the fourth transmission gear 15 and the fifth transmission gear 15, that is, the first position selecting gear 19 corresponds to the first four antenna gears, and the second position selecting gear 19 corresponds to the second four antenna gears. With this arrangement, each of the position selecting gears 19 only controls half of the transmission gears 15 in the transmission shaft 14, and each of the position selecting gears 19 only moves half of the distance in the whole process, so that the length of the gearshift and adjustment device 1 can be reduced compared with the case that a single position selecting gear 19 is used (if the single position selecting gear 19 is used, the single position selecting gear 19 is engaged with all the transmission gears 15, and the single position selecting gear 19 needs to run the whole length of the transmission shaft 14). It should be noted that the number of the positioning gears 19 may be more, for example, three, four, etc., but on the premise that the number of the positioning gears 19 is increased, the distance between the transmission gears 15 needs to be increased (when it is needed to ensure that one transmission gear 15 is in a meshed state, the other transmission gear 15 needs to be in the distance between the other adjacent transmission gears 15), so that two positioning gears 19 are provided as the optimal embodiment.
Further, the position selecting part 11 includes a mounting shaft 20, the mounting shaft 20 is disposed in parallel with the corresponding transmission shaft 14, two position selecting gears 19 are disposed on the mounting shaft 20 at intervals, and each position selecting gear 19 has a movable stroke sliding along the axial direction of the mounting shaft 20 and a movable stroke rotating along the axial direction of the mounting shaft 20; each position selecting gear 19 is used for selecting the corresponding transmission gear 15 in the sliding movable stroke and driving the selected transmission gear 15 to rotate in the rotating movable stroke. It should be noted that the shaft hole of the position selecting gear 19 may be polygonal, and correspondingly, the shaft section of the mounting shaft may also be polygonal, so that the position selecting gear 19 is fixed at the current position without external force, and can rotate axially along with the rotation of the mounting shaft 20 to drive the corresponding transmission gear 15; when external force exists, the position selecting gear 19 can move on the mounting shaft 20 along with the external force, so that the corresponding transmission gear 15 is selected.
It should be noted that, the position selecting driving part 10 is in driving connection with the position selecting gear 19, and when there are many position selecting gears 19, the position selecting driving part 10 drives many position selecting gears 19 to move at the same time, which can effectively simplify the driving source. In the technical solution provided by the present invention, the position selecting portion 11 further includes a mounting sleeve 21 movably sleeved on the mounting shaft 20, two ends of the mounting sleeve 21 are respectively connected to the two position selecting gears 19, the position selecting driving portion is connected to the mounting sleeve 21 for driving the mounting sleeve 21 to slide on the mounting shaft 20, in this case, the two position selecting gears 19 move synchronously with the movement of the mounting sleeve 21. Referring to fig. 4, in a first state, a first position selecting gear 19 is engaged with the first transmission gear 15, and another position selecting gear 19 is disposed between the fourth transmission gear 15 and the fifth transmission gear 15, at this time, if the mounting shaft 20 is driven, namely, the first position selecting gear 19 drives the engaged first transmission gear 15 to rotate, namely, the first antenna gear is output; referring to fig. 5, at this time, the mounting sleeve 21 moves a certain distance, the first positioning gear 19 is located between the first transmission gear 15 and the second transmission gear 15, the second positioning gear 19 is engaged with the fifth transmission gear 15, and at this time, if the mounting shaft 20 is driven, the second positioning gear 19 drives the fifth transmission gear 15 to rotate, i.e., the fifth antenna gear is output, so in this arrangement, the antenna gears are not sequentially output according to the arrangement order as the mounting sleeve 21 moves. It should be noted that, in this way, by using the staggered engagement state of the two position selecting gears 19, it is not necessary to add an additional driving source, and the output of all antenna gears can be completed by driving one mounting shaft 20, which saves the cost and also improves the driving efficiency. In addition, it should be noted that two ends of the mounting sleeve 21 extend to form a clamping seat, the positioning selecting gear 19 is installed on the clamping seat, and the clamping seat has a certain limiting effect on the positioning selecting gear 19.
Further, the position selecting driving portion 10 needs to drive the mounting sleeve 21 to move, in the technical scheme provided by the present invention, the position selecting driving portion 10 includes a driving screw 16, a transmission nut 17 and a first driver 18, the driving screw 16 is parallel to the corresponding mounting shaft 20, the transmission nut 17 is in threaded connection with the driving screw 16, the transmission nut 17 is in driving connection with the mounting sleeve 21, the first driver 18 is in driving connection with the driving screw 16, the driving screw 16 rotates, and the transmission nut 17 moves along the driving screw 16, thereby driving the mounting sleeve 21 to move, and completing the engagement of the position selecting gear 19 and each transmission gear 15. The positioning driving unit 10 may have other driving methods, for example, the mounting sleeve 21 may be driven to move by using an air cylinder, but the footprint of the air cylinder may be large, and the present invention is not limited to the other driving methods.
Furthermore, a first positioning block 27 is arranged at the end of the driving screw 16, a second positioning block 29 is correspondingly arranged on the transmission nut 17, and the first positioning block 27 and the second positioning block 29 are matched with each other for positioning the transmission nut 17. It should be noted that, when the transmission nut 17 moves to the end of the driving screw 16, the first positioning block 27 and the second positioning block 29 contact each other, and at this time, the transmission nut 17 cannot move any more. This position can be considered the zero state, i.e., the initial state, of the device. After each gear shifting is finished, the zero position of the transmission nut 17 is found by driving the driving screw rod 16, so that the whole device can be restored to the initial zero position state to prepare for next gear shifting.
Specifically, the shift drive portion 12 includes a second driver 22, a drive switching member 23, and a first drive gear 24; the driving switching member 23 includes a switching shaft 34, and a first bevel gear 35 and a second driving gear 36 respectively disposed at both ends of the switching shaft 34, wherein the first driving gear 24 is disposed at an end portion of the corresponding mounting shaft 20 and engaged with the second driving gear 36, and the second driver 22 is drivingly connected to the first bevel gear 35. The engagement of the bevel gear with the driving gear can change the direction of the transmission to 90 deg., which can optimize the arrangement inside the device.
Further, in some cases, one shift transmission 9 may not meet the requirement, and thus a plurality of shift transmissions 9 are required to set more antenna stages. In the first arrangement, the shift transmission portion 9 includes a plurality of gear selection portions 11 and the shift driving portion 12; the plurality of shift transmission portions 9 are arranged in order in the horizontal direction, the mounting sleeves 21 of the adjacent positioning portions 11 are connected by the connecting rod 7 extending in the horizontal direction, the positioning drive portion 10 is connected to the mounting sleeve 21 of the first or last positioning portion 11 in a driving manner, and each shift drive portion 12 is connected to the mounting shaft 20 of the corresponding positioning portion 11 in a driving manner. Referring to fig. 7-8, when there are two gear shifting transmission portions 9, the two gear shifting transmission portions 9 are arranged along the horizontal direction, and the position selecting driving portion 10 is connected to the first position selecting portion 11 in a driving manner, and since the two mounting shafts 20 are connected by the connecting rod 7, the movement of the first mounting sleeve 21 drives the movement of the second mounting sleeve 21, and it can be seen that the arrangement of the position selecting gears 19 on the two mounting shafts 20 is the same. It should be noted that, when the position selecting driving portion 10 is driven, both the position selecting portions 11 correspond to one antenna shift position, and since the two antenna shift positions are driven by different shift driving portions 12, the corresponding shift driving portion 12 may be selected to drive the corresponding antenna shift position according to actual needs. It should be further noted that the upper end surface of the mounting base 2 is provided with a spacing groove 37 for moving the connecting rod 7.

first, the first driving rod 30 is driven to rotate forward or backward, and the first straight gear 31, the second bevel gear 28 and the driving screw 16 are sequentially driven to rotate in corresponding rotational directions, so that the driving nut 17 is driven to linearly move forward or backward along the axial direction (a zero position state can be at the end of the driving screw 16 or at the middle of the driving screw 16), and the first positioning block 27 is made to contact with the second positioning block 29, that is, the gearshift adjustment device 1 reaches a zero position. And the first driving rod 30 is controlled to rotate for a set number of turns (each set number of turns corresponds to one antenna gear), so that the two position selecting gears 19 can be driven to linearly move along the axial direction of the mounting shaft 20, and the first position selecting gear 19 is meshed with one transmission gear 15 and then stops. The second driver 22 is driven to rotate in a forward direction or a reverse direction, so that the first bevel gear 35, the second driving gear 36 and the first driving gear 24 can be driven to rotate in sequence. The first driving gear 24 is arranged at the end part of the mounting shaft 20, so that the position selecting gear 19 is also driven to drive the corresponding transmission gear 15 to rotate along the corresponding rotation direction, and further the corresponding gear output piece 13 is driven to rotate, and the gear output piece 13 is connected with a phase shifter for adjusting the downward inclination angle of the antenna, so that the adjustment of the first group of antenna phase shifters is realized;
when the adjustment of the first group of antenna phase shifters is completed, the driving of the second driver 22 is stopped. The first driving rod 30 is driven again to rotate, the zero position starting position of the gear shifting adjusting device 1 is found, and the first driving rod 30 is controlled to rotate for a set number of turns, so that the two positioning gears 19 can be driven to linearly move along the axial direction of the mounting shaft 20, and the positioning gears 19 and other transmission gears 15 are stopped. The second driver 22 is driven to rotate in a forward direction or a reverse direction, so that the first bevel gear 35, the second driving gear 36 and the first driving gear 24 can be driven to rotate in sequence. The first driving gear 24 is arranged at the end part of the mounting shaft 20, so that the position selecting gear 19 is also driven to drive the corresponding transmission gear 15 to rotate along the corresponding rotation direction, and further drive the corresponding gear output piece 13 to rotate, and the gear output piece 13 is connected with a phase shifter for adjusting the downward inclination angle of the antenna, so that the adjustment of the phase shifter of the second group of antennas is realized;
by parity of reasoning, the first driving rod 30 can realize selective meshing of the two position selecting gears 19 and all the transmission gears 15, and then drive the second driver 22 to adjust in the forward direction or the reverse direction, so that adjustment of all the phase shifters is realized, and the purpose of adjusting a plurality of antenna phase shifters by adopting two power sources is achieved. It should be noted that, the use of the plurality of positioning driving portions 10 is similar to that described above, and when the positioning driving portion 10 is driven, the plurality of positioning portions 11 correspond to one antenna stage, and since the plurality of antenna stages are driven by different shift driving portions 12, it is sufficient to select the corresponding shift driving portion 12 to drive the corresponding antenna stage according to actual needs.
It should be noted that, when there is one positioning driving portion 10, the axes of the screw, the gear and other components used in the shift adjusting device 1 can be set on the same flat layer, so that the thickness of the entire shift adjusting device 1 can be made very thin, and the height has great advantage in height compared with the scheme of stacking and staggering the shift components in a height space in the cylindrical layout or the shift components in the same field. Of course, when there are a plurality of positioning driving units 10, the axes of the screw, gear, and other components used for each layer or each unit may be arranged on the same level, which also optimizes the overall layout and improves the compactness of the device.
