Description

Clamping device for antenna {CLAMPING APPARATUS FOR ANTENNA}

For example, if the number of antennas is increased to 10, a channel capacity of about 10 times is secured using the same frequency band compared to the current single antenna system.

In 4G LTE-advanced, up to 8 antennas are used, and products with 64 or 128 antennas are currently being developed in the pre-5G stage, and base station equipment with a much larger number of antennas is expected to be used in 5G. , This is called Massive MIMO technology. While the current cell operation is 2-Dimension, it is also called FD-MIMO (Full Dimension) because 3D-Beamforming becomes possible when Massive MIMO technology is introduced.

In Massive MIMO technology, as the number of ANTs increases, the number of transmitters and filters increases accordingly. Nevertheless, it is a reality to make RF parts (Antenna/Filter/Power Amplifier/Transceiver etc.) small, light and inexpensive due to the lease cost and space constraints of the installation site, and Massive MIMO requires high output for coverage expansion. Power consumption and heat generation due to such high output are acting as negative factors in reducing weight and size.

In particular, when a MIMO antenna in which RF elements and modules implemented with digital elements are combined in a stacked structure is installed in a confined space, compactness of a plurality of layers constituting the MIMO antenna and The necessity of miniaturization design has emerged, and there is a strong demand for free direction control of an antenna device installed on one support pole.

However, the tilting rotation adjustment gear set 350 is different in that the tilting adjustment caps 301 and 302 are axially connected to one end and the other end of the worm gear 353 via the cap shaft 302a.

6 is a perspective view showing another embodiment of a clamping device for an antenna according to the present invention, and FIG. 7 is an exploded perspective view of FIG. 6.

In the clamping device for an antenna according to an embodiment of the present invention described through FIGS. 4 and 5, the tilting unit 100 is coupled to the coupling unit 30, and the rotation unit 200 is coupled to the tilting unit 100. It will be described as an embodiment in which the antenna device A is mounted on the rotation unit 200.

However, in another embodiment of the clamping device for an antenna according to the present invention, which will be described later, as shown in FIGS. 6 and 7, the rotation unit 200 can rotate in the left and right direction at the front end of the coupling unit 30 Is installed in the front end of the rotation unit 200 so that the tilting unit 100 can be tilted and rotated in the vertical direction, and the bolt flange 112 on which the antenna device A is installed is fastened to the tilting unit 100 It can be mounted in the hole 113.

Tilting and rotating operations are defined as'tilting' when the antenna device (A) is rotated in the vertical direction centering on the installed position, and'rotating' when the antenna device (A) is rotated in the left-right direction around the installed position. Since it is only a difference according to the result defined as'Ting', the clamping device 10' for an antenna according to another embodiment of the present invention is configured to move the clamping device 10 for an antenna according to an embodiment of the present invention in a 90 degree direction. It is only the difference between the embodiment rotated by.

However, as described above, the rotation adjustment unit does not have to be provided in all of the tilting unit 100 and the rotation unit 200, and as shown in FIG. 7, only the tilting rotation adjustment gear set ( 350) may be provided.

For the specific configuration and coupling relationship of the tilting rotation adjustment gear set 350, the description of the tilting rotation adjustment gear set 350 of the configuration of the clamping device 10 for an antenna according to an embodiment of the present invention described above will be substituted. .

In this way, the reason why the rotation adjustment unit is provided only in the tilting unit 100 is, in addition to the weight of the antenna device A itself, as a result of the antenna device A being installed outside where wind or the like is blowing, the residual vibration transmitted from the outside This is because the tilting of the tilting unit 100 is more concerned. That is, in the case of the rotation unit 200, the influence of the weight of the antenna device A is less, because the room for random rotation is reduced compared to the tilting unit 100.

Here, the tilting rotation adjustment gear set 250 is a function for simply tilting and rotating the tilting unit 1100, and further, random rotation according to residual vibration through the engagement of the worm gear 253 and the worm wheel gear 254 It also performs an additional function as a rotation prevention unit that prevents the problem. This can be more easily understood from the fact that it is implemented in a new form called the addition of a separate rotation preventing unit in the clamping device for an antenna according to another embodiment of the present invention described with reference to FIGS. 8 to 10B to be described later. have.

8 is a perspective view showing another embodiment of a clamping device for an antenna according to the present invention, FIGS. 9A and 9B are a simplified exploded perspective view and a detailed exploded perspective view of FIG. 8, and FIGS. 10A and 10B are the rotating of FIG. It is an exploded perspective view showing another example of a rotation adjustment gear set and a tilting rotation adjustment gear set.

Another embodiment (10") of the clamping device for an antenna according to the present invention is a rotation unit coupled to enable rotation and rotation in the left and right directions via the coupling unit 30 as shown in FIGS. 8 to 9B. 200 and a tilting unit 100 coupled to the rotation unit 200 so as to tilt and rotate in the vertical direction.

In addition, an antenna clamping device 10" according to another embodiment of the present invention is provided in at least one of the rotation unit 200 and the tilting unit 100, as shown in FIGS. 9A and 9B, , It may further include rotation preventing units (270, 370) for preventing angle change due to vibration or impact due to external force.

Here, the rotating rotation adjustment gear set 350 and the tilting rotation adjustment gear set 250 are at least one rotation motor 251,351 shaft-coupled with the worm gears 252 and 352, as shown in FIGS. 9A and 9B. Can be automatically driven by

More specifically, the rotating rotation adjustment gear set 350 is a worm gear 352 that is axially rotated by the rotating rotation motor 351 and the rotating rotation motor 351, as shown in FIG. 9B. Wow, a worm wheel gear 353 provided to mesh with the worm gear 352 and a rotating shaft 359 to which the worm wheel gear 353 is axially coupled.

Here, at the front end of the rotating shaft 359, a shaft hole 359a to which the rotating shaft 221 of the rotation unit 200 is axially coupled is formed, and a rotating shaft 221 is formed in the shaft hole 359a. It can be fitted and rotated interlocking.

The rotating rotation adjustment gear set 350 rotates the rotating shaft 359 by meshing rotation of the worm gear 352 and the worm wheel gear 353 according to the direction in which the rotating rotation motor 351 is driven to rotate. By automatically rotating the rotating shaft 221 connected thereto by an operation to rotate, the rotation unit 200 may be rotated in the left and right directions.

On the other hand, the tilting rotation adjustment gear set 250, only the tilting shaft 111 that is shaft-coupled with the rotating rotation adjustment gear set 350 is different, all of the same configuration and combination as the rotating rotation adjustment gear set 350 Since it has a relationship, its detailed description will be omitted.

Each of the rotation prevention gears 373 and 273 may be driven by the rotation prevention motors 371 and 271 provided in the coupling unit 30 and the rotation unit 200.

Here, the rotation preventing motors 371 and 271 are spur gears 372 and 272 that are directly coupled to the motor shaft and rotated by axis, as shown in FIGS. 9A and 9B, and the spur gears are provided inside the motor box, and are not shown separately. (Indicated by a dotted line) and the anti-rotation gears 373 and 273 may be provided to directly engage.

As such, the rotation prevention units 370 and 270 use the mutual friction force of the pair of tilting brake washer pads 274 in the case of the tilting unit 100, or in the case of the rotating unit 200, a pair of rotating By using the mutual friction force of the brake washer pads 374, the tilting shaft 259 and the rotating shaft 359 are not rotated arbitrarily, so that the tilting unit 100 and the rotating unit 200 are separated by residual vibration according to the external environment. It can prevent damage.

More specifically, in the case of the tilting unit 100, when the rotation prevention motor 371 of the rotation prevention unit 270 is electrically driven, the spur gear 372 provided in the motor box rotates and the rotation prevention gear engaged therewith. As the rotation prevention gear 273 is rotated on the tilting shaft 259, the pair of tilting brake washer pads 274 are brought into close contact with each other to generate a predetermined frictional force. In a state in which such frictional force is generated, even if residual vibration is transmitted from the outside, it is possible to prevent arbitrary tilting while continuously maintaining gear engagement of the tilting rotation adjustment gear set 250.

In the case of the rotation unit 200, the same function as the tilting unit 100 may be performed by using the rotation preventing unit 370. The detailed description will be replaced with the description of the rotation preventing unit 270 of the tilting unit 100.

For example, in the case of the embodiments of FIGS. 9A and 9B in which the worm gears 272 and 372 are not provided, the rotational shafts of the rotation prevention motors 271 and 371 must be designed coaxially with the rotational shafts of the spur gears 272 and 372. 10A and 10B, when the worm gears 272 and 372 are replaced, rotation prevention motors 271 and 371 are applied by adjusting the length of the worm gears 272 and 372 to the limit in which the worm gears 272 and 372 are engaged with the spur gears 276 and 376. The degree of freedom of design for the fixed position of the can be improved.

On the other hand, as shown in FIG. 10B, when a separate worm gear () is not provided, as described above, a two-stage transmission that meshes with the spur gears 272 and 372 in the motor box and meshes with the rotation prevention gears 273 and 373 It is provided as gears 276 and 376 so that the rotational driving force of the rotation prevention motor 2351 is transmitted to the rotation prevention gear 2353 through the spur gears 272 and 372 and the second transmission gears 276 and 376.

In addition, when the rotation prevention parts 270 and 370 according to the present embodiment are driven and rotated by the rotation prevention gears 273 and 373 by the rotation prevention motors 271 and 371, a pair of rotating brake washers pads 374 or the pair of tilting brake washers As the pads 274 are in close contact with each other, frictional force increases, and accordingly, arbitrary rotation due to external force may be prevented.

Meanwhile, in the clamping device 10" for an antenna device according to another embodiment of the present invention described with reference to FIGS. 8 to 10B, each of the rotation adjustment units 250 and 350 and the rotation prevention units 270 and 370 is a rotation motor Since electrical driving of the rotation prevention motors 271 and 371 is required, the coupling unit 30 and the rotation unit 200 need to be electrically connected to each other. For this purpose, the lower end of the rotation unit 200 needs to be connected to each other. The wire protection case 223 is separately provided, and electrical wires of the rotation unit 200 and the coupling unit 30 can be connected through the wire coupling hole 224 formed in the wire protection case 223.

In this embodiment, as to prevent arbitrary rotation of the tilting unit 100, the damping unit 370 ′ is coupled to the coupling unit 30 in which the tilting rotation adjustment gear set 350 of the tilting unit 100 is embedded. It will be described on the premise that the housing 331 is provided inside.

Inside the coupling housing 331, as shown in Figs. 11 and 12, the worm gear 352 of the tilting rotation adjustment gear set 350 is attached to the outer side of the mounting bracket 340 to be installed, the coupling housing ( Both ends may be provided in the form of a leaf spring that is in close contact with a portion of the inner surface of the 331 and elastically supports the entire installation bracket 340 toward the worm wheel gear 353.

In addition, the elastic support surface 370c extending from the bent surface 370b is preferably formed to be bent at an angle corresponding to a portion of the inner surface in contact with the coupling housing 331.

In this way, the rotation prevention unit 370 ′ in the form of a leaf spring continuously contacts the installation bracket 340 to the worm wheel gear 353 side, so that the worm gear 352 and the worm wheel gear 353 are randomly engaged. By not being released, it is possible to prevent the gap phenomenon caused by the above-described residual vibration.
