Description

Electrical downtilt angle control device for multi-system antenna and antenna

Technical Field

The utility model relates to a wireless communication field, concretely relates to multisystem antenna electrical downtilt angle controlling means and antenna.

Background

In the field of mobile communications, it is often necessary to change the radiation plane of an antenna by adjusting the electrical downtilt of a base station antenna to implement adjustment of the network coverage area. The specific adjustment process is to drive the phase shifter through the transmission device, so as to change the electrical downtilt angle of the base station antenna.

With the development of mobile communication technology, a multi-system transmission device using a dual-motor structure (one motor controls the position selection adjustment, and the other motor controls the drive adjustment) is a mainstream scheme adopted in the industry at present. According to different layout characteristics of a driving structure, the implementation modes of the antenna electrical downtilt angle control device with the current dual-motor structure mainly comprise a circumferential mode and a spreading mode.

The circumferential antenna electrical downtilt angle control device usually drives multiple systems through a gear structure distributed circumferentially, and has the advantages of compact overall structure, few transmission stages and high transmission efficiency. The electric downtilt angle control device of the tiled antenna is characterized in that a driving module in the device is tiled in the width direction of the antenna and is connected with the driving module from the input end of a motor through gear transmission, and the connection span of the phase shifting device and the transmission device is small, so that the transmission layout of antenna products is facilitated.

However, there are problems associated with both types of antenna electrical downtilt control devices in particular antenna product applications: on one hand, the circumferential structure can only be limited to drive a small number of phase shifter units under the condition of a given height space, and for antennas of more systems, at least two sets of transmission devices are required to be matched for use simultaneously, so that the cost of the antenna is greatly increased. On the other hand, in engineering practice, the matching performance of the circumferential structure and the phase shifter unit required by the antenna is poor in layout, the switching span from the control device to the phase shifter unit is large, the transmission driving force can enable the sliding medium of the phase shifter to be subjected to a larger additional torque action under the superposition of the overlarge switching span, the smooth sliding of the sliding medium is influenced, the guide structure of the sliding medium can be broken and failed under the action of the overlarge additional torque, and meanwhile, the accuracy of phase adjustment of the phase shifter is easily influenced by the action of the additional torque. The tiled structure also has the problems of multiple transmission stages and low transmission efficiency, the transmission efficiency and the transmission precision obtained by each drive module are different, and the phase adjusting precision of the phase shifter is low.

In view of this, it is urgently needed to develop an antenna electrical downtilt control device, which can implement independent and accurate control of electrical downtilts of a plurality of antenna systems, and has the advantages of compact structure, small adjustment error, flexible and various connection with a phase shifter, good product layout and high reliability.

Specifically, in the preferred embodiment of the present invention, the transmission channel interface is a hole-tooth type female coupling interface 430, and the power output interface is a pin-tooth type male coupling interface 2230.

Generally, each gear of the first drive gear set and the second drive gear set is of a cylindrical gear structure.

Specifically, the first driving wheel 220 and the second driving wheel 320 have a pin structure at one end of their centers, respectively, for being sleeved with the cylindrical boss structures at one ends of the first selecting gear 210 and the second selecting gear 310, respectively, and the other ends are provided with inner fastening holes, which can be sleeved with the power rotating shaft of the driving motor.

Specifically, in the embodiment of the present invention, the third driven wheel 223 has a pin hole in one end thereof for being sleeved with the blade handle 2121 of the selected position slanted ejecting block 212 in a simple hole-shaft manner, and the other end thereof is a pin shaft structure and is provided with a pin-tooth-shaped male coupling interface 2230 at the outer end of the pin shaft.

Specifically, the front end and the rear end of the power driving shaft 23 are rotatably sleeved in the central holes of the front cover 212 and the rear cover 242 in the box base assembly 24, and are respectively connected with the first driven wheel 221 and the rear second driven wheel 222 in a special-shaped pin-and-pin hole transmission manner, so that the first driven wheel 221 and the second driven wheel 222 can synchronously rotate, and the power of the driving motor is output from the power channel selection area 2401 at the front end of the box base to the power output area at the rear side.

Particularly, when the number of transmission channels of a single transmission assembly is sufficient, it is preferable that the first transmission assembly 2 or the second transmission assembly 3 is matched with the positioning selection assembly 1 to realize the control of the antenna electrical downtilt angle according to the product layout requirements.

As shown in fig. 6, the phase shift assembly 4 includes a front support plate 41, a rear support plate 42, a phase shift screw 43, and a threaded slider 44.

Specifically, a plurality of sets of positioning holes distributed circumferentially are arranged on the front support plate 41 and the rear support plate 42, and the positions of the positioning holes correspond to the positions of the power output parts of the first transmission assembly 2 and the second transmission assembly 3 one by one.

The front and rear ends of the phase shift screw 43 are respectively rotatably sleeved in the positioning holes of the front support plate 41 and the rear support plate 42. The threaded slider 44 is arranged corresponding to the phase-shifting screw 43, and the threaded slider 44 can be driven to move back and forth along the axial direction by the circumferential rotation of the screw.

Further, a hole-tooth-shaped female coupling interface 430 is arranged at the front end of the phase-shifting screw 43, and the hole-tooth-shaped female coupling interface 430 and the pin-tooth-shaped male coupling interface 2230 on the third driven wheel 223 can form a radial clamping connection in structural form, so that when the male coupling interface 430 and the female coupling interface 2230 form a radial clamping connection, the self-rotation energy of the third driven wheel 223 drives the phase-shifting screw 43 to synchronously rotate, thereby completing power output.

The specific motion mechanism of the multi-system antenna electrical downtilt angle control device is as follows:

before the position selection, the hole-tooth-shaped female coupling interface 430 of the phase shift screw 43 and the male coupling interface 2230 of the third driven wheel 223 have a certain distance in the axial direction, that is, no engagement occurs between the male coupling interface 430 and the female coupling interface 2230.

Firstly, selecting the position: when the position selecting motor rotates clockwise, the pawl sheet 1102 of the first pawl group 1100 is clamped with the inner teeth 1110 of the first position selecting ratchet 111, and drives the first position selecting ratchet 111 to rotate clockwise. The clockwise rotation of the first position selecting ratchet 111 drives the first position selecting gear 210 to rotate counterclockwise, and further drives the third position selecting gear 211 to rotate clockwise.

In the process that the third positioning gear 211 rotates clockwise, the positioning structure 2111 integrally formed with the third positioning gear 211 moves circumferentially along the axis of the third positioning gear 211 and contacts the positioning inclined ejecting blocks 212 circumferentially distributed and mounted on the box base body 240.

When the position selecting structure 2111 rotates and contacts a non-preset position selecting inclined top block 212, the position selecting inclined top block 212 contacts an inclined top surface on the position selecting structure 2111 and forms an inclined wedge mechanism, so that the position selecting inclined top block 212 moves backwards along the axial direction, and meanwhile, the return spring 224 is further compressed until the position selecting structure 2111 of the third position selecting gear 211 completely slides through the position selecting inclined top block 212. After the position selecting structure 2111 of the third position selecting gear 211 completely slides over the non-preset position selecting lifter block 212, the third driven wheel 223 with the position selecting lifter block 212 will quickly spring back to be attached to the rear mounting surface of the inner wall 2400 of the box base body 240 in the axial direction under the reaction force of the compression spring 224.

When the rotation angle of the position selecting motor is controlled until the position selecting structure 2111 reaches the position selecting inclined ejecting block 212 where the preset required driving channel is located, the long handle structure with the inclined ejecting of the position selecting structure 2111 can hover at the center of the position selecting inclined ejecting block 212, and the position selecting inclined ejecting block 212 drives the third driven wheel 223 connected with the position selecting inclined ejecting block to move backwards, so that more third driven wheels 223 extend out of the box body rear cover 242. At this time, the pin-tooth type male coupling port 2230 of the third driven wheel 223 is engaged with the hole-tooth type female coupling port 430 of the corresponding phase shift screw 43 in the phase shift unit 4.

On the contrary, when the position selecting motor rotates counterclockwise, the pawl sheet 1102 of the second pawl group 1101 is clamped with the inner teeth 1110 of the second position selecting ratchet 112, and drives the second position selecting ratchet 112 to rotate counterclockwise. The counterclockwise rotation of the second positioning selection ratchet 112 drives the second positioning selection gear 310 to rotate clockwise, and further drives the third positioning selection gear 211 to rotate counterclockwise.

Similar to the above process, when the rotation angle of the position selecting motor is controlled until the position selecting structure 2111 reaches the position selecting lifter block 212 where the preset required driving channel is located, the long-handle structure with the lifter of the position selecting structure 2111 is suspended at the center of the position selecting slider 212, and the position selecting lifter block 212 drives the third driven wheel 223 connected thereto to move backward, so that more of the third driven wheel 223 extends out of the box body rear cover 242. At this time, the pin-tooth type male coupling port 2230 of the third driven wheel 223 is engaged with the hole-tooth type female coupling port 430 of the corresponding phase shift screw 43 in the phase shift unit 4.

And secondly, driving: after the position selecting process is completed, the driving motor rotates, in the first transmission assembly 2, the first driving wheel 220 drives the first driven wheel 221 engaged with the first driving wheel and the second driven wheel 222 coaxial with the first driven wheel 221, so as to drive third driven wheels 223 uniformly distributed according to the circumference and engaged with the second driven wheels, and after a driving channel is selected, the third driven wheels 223 corresponding to the channel complete power output through the phase shifting screw 43 coupled and clamped with the third driven wheels, so as to realize the phase shifting driving of the corresponding phase shifter unit.

In the second transmission assembly 3, the first driving wheel 220 drives the power transmission wheel 113 engaged therewith, and further drives the second driving wheel 320, the first driven wheel 221 and the second driven wheel 222 coaxial with the first driven wheel 221, so as to further drive third driven wheels 223 uniformly distributed circumferentially and engaged with the second driven wheels 222, and after a driving channel is selected, the third driven wheels 223 corresponding to the channel complete power output through the phase shifting screws 43 coupled and clamped therewith, so as to realize phase shifting driving of corresponding phase shifter units.

It should be noted that all the third driven wheels 223 of the first transmission assembly 2 and all the third driven wheels 223 of the second transmission assembly 3 rotate simultaneously, but only the third driven wheel 223 with the preset required driving channel can be in a meshed state with the preset phase shifting screw 43, so that only the preset phase shifting screw 43 can be driven to rotate, and further the threaded sliding block 44 and the pull rod connected with the threaded sliding block are driven to do a back-and-forth linear motion, and finally the phase shifter medium is driven to slide. While the other non-preset third driven pulley 223 is in an idling state and the other non-preset phase shift screw 43 is in a stationary state.

It should also be noted that the positioning component 1 can be used with the first transmission component 2 and the second transmission component 3 at the same time for driving an ultra-multiple system antenna, or can be used with only the first transmission component 2 or the second transmission component 3 for driving a smaller number of system antennas. In addition, the first transmission assembly 2 and the second transmission assembly 3 may also be used to drive fewer system antennas, and at this time, the third driven wheels 223 of the first transmission assembly 2 and the second transmission assembly 3 are not all installed, but are selectively installed as needed, so that the position of the preset phase shifting screw 43 can be more flexibly selected while the cost is kept substantially unchanged, and further, the connection with the phase shifter is more free.

The embodiment of the utility model provides a still provide an antenna, including above-mentioned arbitrary one a multisystem antenna electrical downtilt angle controlling means.
