Description

Antenna phase adjusting device

Technical Field

The utility model relates to the technical field of antenna phase adjustment, in particular to an antenna phase adjusting device.

Background

The electrically tunable antenna means a mobile antenna which uses an electric adjusting device to adjust the phase shift of a phase shifter so as to realize the adjustment of a downward inclination angle. Because the displacement adjusting precision of telescopic linear driving mechanisms such as air cylinders is low, common electric adjusting devices all adopt a motor screw rod structure. Most of the existing electrically tunable antennas are provided with a set of electric adjusting devices for each phase shifter. In the past, a single antenna included a smaller number of phase shifters, and a set of electric adjustment devices for each phase shifter was less problematic. In recent years, with the development of the 5G technology, the number of phase shifters included in a single antenna is increasing, and if a group of electric adjusting devices is continuously arranged for each phase shifter, the volume, weight and manufacturing cost of the electric adjusting antenna will all rise sharply, which is not favorable for the popularization of the 5G technology.

Therefore, the existing electric adjusting device needs to be improved to solve the problem that the volume, the quality and the cost of the electric tuning antenna are high because the electric tuning antenna can only adjust a single phase shifter.

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

The utility model provides an antenna phase adjusting device which is suitable for an application scene of carrying out independent position adjustment on a plurality of phase shifters in an electric tilt antenna, can realize independent adjustment of the plurality of phase shifters by only using two motors, and is beneficial to reducing the volume, the quality and the cost of the electric tilt antenna.

Referring to fig. 1 to 3, in this embodiment, the antenna phase adjusting apparatus includes a phase shifting assembly 1 for connecting with a plurality of phase shifters, a fixed phase shifting transmission assembly 2 in transmission connection with the phase shifting assembly 1, a sliding phase shifting transmission assembly 3 in transmission connection with the fixed phase shifting transmission assembly 2 after being driven, a gear shifting assembly 4 for driving the sliding phase shifting transmission assembly 3 to be in transmission connection with or separated from the fixed phase shifting transmission assembly 2, and a phase shifting driving assembly 5 for driving the sliding phase shifting transmission assembly 3 to rotate.

The phase shifting assembly 1 comprises a plurality of phase shifting screw rods 101 arranged at intervals, the plurality of phase shifting screw rods 101 are longitudinally arranged, and each phase shifting screw rod 101 is provided with a movable base 102 in threaded connection with the phase shifting screw rod 101. Each of the moving bases 102 may be fixed with a phase shifter, so that when the phase shifting screw rods 101 rotate, the corresponding moving base 102 may be driven to move back and forth, and further the phase shift of the corresponding phase shifter may be adjusted, that is, each of the phase shifting screw rods 101 may adjust the phase shift of one phase shifter.

Each phase shifting screw 101 is provided with a bevel gear 1011 at the end near the fixed gear 202.

The fixed phase-shifting transmission assembly 2 is arranged between the phase-shifting screw rods 101 and the sliding phase-shifting transmission assembly 3 and comprises an installation rotating shaft 201 and a plurality of fixed gears 202 installed on the installation rotating shaft 201. The installation rotating shaft 201 is transversely arranged. Each of the fixed gears 202 is engaged with the corresponding phase shifting screw 101 through a bevel gear 1011, and each of the fixed gears 202 is pivotally mounted on the mounting shaft 201, so that the fixed gears 202 can rotate independently from each other, that is, each of the fixed gears 202 rotates independently from the mounting shaft 201, and further, the fixed gears 202 can rotate independently from the mounting shaft 201 by sleeving a bearing on the mounting shaft 201 and then sleeving the fixed gears 202 on the bearing. The arrangement is such that, when one fixed gear 202 rotates, the other fixed gear 202 is not rotated, so that the rotational adjustment of the single phase-shifting screw 101 is realized.

Further, although the fixed gears 202 rotate around the mounting rotating shaft 201 independently, when one fixed gear 202 rotates, the mounting rotating shaft 201 is inevitably driven to deform to some extent, and the deformation of the mounting rotating shaft 201 may drive other fixed gears 202 to slightly rotate, which may finally cause the phase shifters on other phase shifting screws 101 to slightly shift positions. In order to avoid such a situation, the antenna phase adjustment apparatus provided in the present embodiment is further provided with a limit component 6.

The limiting assembly 6 comprises a plurality of limiting sliding plates 601 and a plurality of return springs 602. Wherein each of the limit sliding plates 601 is opposite to one of the fixed gears 202; each of the return springs 602 is disposed corresponding to one of the limit sliding plates 601, and the return springs 602 are disposed at an end of the corresponding limit sliding plate 601 away from the corresponding fixed gear 202 and are configured to apply a force to the corresponding limit sliding plate 601 toward the corresponding fixed gear 202, so that when the return springs 602 push the limit sliding plates 601 to abut against the corresponding fixed gear 202, the limit sliding plates 601 abut against the fixed gear 202 to prevent the fixed gear 202 from rotating, and only when the limit sliding plates 601 are pushed away to be disengaged from abutting against the fixed gear 202, the fixed gear 202 can be driven to rotate.

The sliding phase shift transmission assembly 3 comprises a sliding rotating shaft 301 and a sliding gear 302 sleeved on the sliding rotating shaft 301. The slide rotation shaft 301 is disposed laterally. The sliding gear 302 rotates synchronously with the sliding rotating shaft 301, and the sliding gear 302 can slide along the sliding rotating shaft 301. Further, referring to fig. 4, the sliding gear 302 includes two gear bodies 3021 and a connecting sleeve 3022 located between the two gear bodies 3021, and the distance between the outer sides of two adjacent gear bodies 3021 is smaller than the distance between the inner sides of two adjacent fixed gears 202, so that the sliding gear 302 can only mesh with one fixed gear 202 at a time, and thus the sliding gear 301 can rotate the sliding gear 302, and the sliding gear 302 can rotate the fixed gear 202, so that the fixed gear 202 drives the phase shift screw 101 to rotate through the corresponding bevel gear 1011, and thus the corresponding movable base 102 is driven to move back and forth to adjust the phase shift of one phase shifter.

The shifting assembly 4 is configured to drive the sliding gear 302 to move along the sliding rotation shaft 301 to a position where the sliding gear 302 is engaged with a corresponding fixed gear 202, so that the sliding gear 302 drives the fixed gear 202 to rotate, and the fixed gear 202 drives the corresponding phase shifting screw 101 to rotate through the bevel gear 1011. In this embodiment, the shift assembly 4 includes a shift block 401, a shift screw 402, a shift transmission gear 403, and a shift interface 404.

One side of the shift shifting block 401, which is close to the phase shifting screw rod 101, extends into a space between the two gear main bodies 3021 and is provided with an arc-shaped notch 4013 through which the connecting sleeve 3022 passes, so that when the shift shifting block 401 moves transversely, the sliding gear 302 is driven to move to a corresponding position to be meshed with a fixed gear 202, and when the sliding gear 302 rotates, the shift shifting block 401 does not interfere with the rotation of the sliding gear 302; the other side of the gear shifting block 401, which is close to the limiting sliding plate 601, is provided with a guide boss 4011, and the boss 4011 is abutted to the limiting sliding plate 601 and used for driving the limiting sliding plate 601 to move towards the fixed gear 202 away from the corresponding limiting sliding plate 601. Further, guide inclined surfaces 4012 for guiding the limit sliding plate 601 to slide away from the corresponding fixed gear 202 are disposed at two ends of the guide boss 4011.

The shift screw rod 402 is arranged in parallel with the sliding rotating shaft 301, the shift screw rod 402 penetrates through the shift block 401 and is in threaded connection with the shift block 401, when the shift screw rod 402 rotates, the shift block 401 can be driven to move transversely along the shift screw rod 402, and the sliding gear 302 is driven to move transversely to a position meshed with a bevel gear 1011, so that the sliding gear 302 is meshed with the bevel gear 1011.

The gear shifting transmission gear 403 is sleeved on the gear shifting screw rod 402 and is synchronously and rotatably connected with the gear shifting screw rod 402; one end of the gear shifting interface 404 is used for being in transmission connection with a gear shifting motor, and the other end of the gear shifting interface 404 is in transmission connection with the gear shifting transmission gear 403, so that when the gear shifting motor is started, the gear shifting screw rod 402 can be driven to rotate sequentially through the gear shifting interface 404 and the gear shifting transmission gear 403.

The phase-shifting driving assembly 5 comprises a middle phase-shifting transmission gear 501, an end phase-shifting transmission gear 502 and a phase-shifting interface 503. The intermediate phase shift transmission gear 501 is pivoted to the shift screw 402 and does not rotate synchronously with the shift screw 402. The end part phase shift transmission gear 502 is sleeved on the sliding rotating shaft 301 and is synchronously and rotatably connected with the sliding rotating shaft 301; the end part phase-shifting transmission gear 502 is meshed with the middle phase-shifting transmission gear 501; one end of the phase-shifting interface 503 is used for being in transmission connection with the phase-shifting motor, and the other end of the phase-shifting interface 503 is in transmission connection with the intermediate phase-shifting transmission gear 501. Therefore, when the phase-shifting motor is started, the sliding rotating shaft 301 can be driven to rotate through the phase-shifting interface 503, the middle phase-shifting transmission gear 501 and the end phase-shifting transmission gear 502 in sequence, so that the sliding rotating shaft 301 drives the sliding gear 302 to rotate, and the sliding gear 302 drives the corresponding fixed gear 202 to drive the corresponding phase-shifting screw rod 101 to rotate.

At the beginning, the following operating states can be set:

firstly, each sliding seat is connected with a phase shifter;

the sliding gear 302 is just positioned between the two limiting sliding plates 601, and any limiting sliding plate 601 is not pushed out;

thirdly, each fixed gear 202 is propped by a limiting sliding plate 601 and cannot rotate;

and fourthly, both the gear shifting motor and the phase shifting motor are in a closed state.

When the position of a certain phase shifter needs to be adjusted, taking the phase shifter at the leftmost end as an example, the working process of the antenna phase adjusting device provided in this embodiment is as follows:

s10: the gear shifting motor is started, the gear shifting screw rod 402 is driven to rotate through the gear shifting interface 404 and the gear shifting transmission gear 403 in sequence, the gear shifting block 401 is shifted, and the sliding gear 302 is moved to be meshed with the fixed gear 202 at the leftmost end through the gear shifting block 401;

it should be noted that, in the process of the shift block 401 moving the sliding gear 302 to engage with the leftmost fixed gear 202, the leftmost limit slide plate 601 is pushed to the side away from the fixed gear 202 along the guide inclined surface 4012 of the guide boss 4011 and presses the return spring 602, so as to release the rotation restriction of the leftmost fixed gear 202;

it is worth noting that since the intermediate phase shift transmission gear 501 is pivoted on the gear shift screw rod 402 and does not synchronously rotate with the gear shift screw rod 402, when the gear shift screw rod 402 rotates, the intermediate phase shift transmission gear 501 does not rotate, thereby preventing the gear shift screw rod 402 from driving the end phase shift transmission gear 502 to rotate;

s20: the phase shifting motor is started, the sliding rotating shaft 301 is driven to rotate through the phase shifting interface 503, the middle phase shifting transmission gear 501 and the end phase shifting transmission gear 502 in sequence, and then the sliding gear 302 rotates, and only the fixed gear 202 at the leftmost end and the sliding gear 302 are in a meshed state and the rotation limitation of the limiting sliding plate 601 is removed, so that when the sliding gear 302 rotates, only the fixed gear 202 at the leftmost end can rotate, and other fixed gears 202 keep a static state, the effects that only the phase shifting screw rod 101 at the leftmost end rotates and other phase shifting screw rods 101 do not rotate can be achieved, and finally the purpose that only the phase shifter at the leftmost end is subjected to position adjustment is achieved.

It should be noted that, since the intermediate phase shift transmission gear 501 does not rotate synchronously with the gear shift screw 402, when the intermediate phase shift transmission gear 501 rotates, the gear shift screw 402 does not rotate, thereby avoiding the influence of the rotation of the intermediate phase shift transmission gear 501 on the position of the gear shift block 401.

It can be understood that when the individual position adjustment of different phase shifters is required, the position of the shift block 401 only needs to be adjusted to the corresponding limit slide plate 601.

In conclusion, the antenna phase adjusting device provided by the embodiment can realize the position adjustment of any number of phase shifters only by the two motors such as the gear shifting motor and the phase shifting motor, greatly reduces the volume, the weight and the manufacturing cost of the electrically tunable antenna, and has a great promoting effect on the promotion of the 5G technology and the 4G/5G hybrid technology.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
