Description

[Technical Field]

[0001] The present invention relates to a clamping apparatus for an antenna device, and more particularly to a clamping apparatus for an antenna device that allows efficient placement of an antenna device in a crowded installation space and facilitates adjustment of the direction of the antenna device. [Background technology]

[0002] Generally, wireless communication technology, for example, MIMO (Multiple Input Multiple Output) technology, is a technology that dramatically increases data transmission capacity by using multiple antennas. It is a spatial multiplexing technique in which a transmitter transmits different data through each transmitting antenna, and a receiver separates the transmitted data through appropriate signal processing.

[0003] Therefore, by simultaneously increasing the number of transmitting and receiving antennas, the channel capacity increases, enabling more data to be transmitted. For example, increasing the number of antennas to 10 secures approximately 10 times the channel capacity compared to the current single antenna system using the same frequency band.

[0004] 4G LTE-advanced uses up to eight antennas, and currently, products equipped with 64 or 128 antennas are being developed in the pre-5G stage, and it is expected that base station equipment with a much larger number of antennas will be used in 5G, which is called Massive MIMO technology. While current cell operations are 2-dimensional, the introduction of Massive MIMO technology will enable 3D-Beamforming, so it is also called FD-MIMO (Full Dimension).

[0005] In Massive MIMO technology, as the number of ANTs (antennas) increases, the number of transmitters and filters also increases. However, due to the cost of leasing installation sites and spatial constraints, it is practical to make RF components (antennas / filters / power amplifiers / transceivers, etc.) small, light, and inexpensive. Massive MIMO requires high output power to expand coverage, but the power consumption and heat generated by such high output power act as a negative factor in reducing weight and size.

[0006] In particular, when a MIMO antenna, in which modules realizing RF elements and digital elements are combined in a stacked structure, is installed in a limited space, there is a need for a compact and miniaturized design for the multiple layers that make up the MIMO antenna in order to maximize ease of installation and space utilization. There is also a strong demand for the ability to freely adjust the direction of an antenna device installed on a single support pole.

[0007] In response to the above-mentioned requirement, Korean Patent Publication No. 10-2095871 (published on April 2, 2020) (hereinafter referred to as "Prior Art") discloses an "antenna clamping device" equipped with a tilting unit for rotating an antenna device in the vertical direction and a steering unit for rotating the antenna device in the horizontal direction.

[0008] However, the conventional technology has a problem in that the tilting unit has a small range of rotation for the antenna in the up and down direction. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A clamping device for an antenna device according to an embodiment of the present invention will now be described with reference to the drawings.

[0031] FIG. 1 is a perspective view showing an antenna device tilted while installed on a support, FIG. 2 is a front perspective view showing the clamping device for the antenna device shown in FIG. 1, and FIG. 3 is a rear perspective view showing the clamping device for the antenna shown in FIG. 1.

[0032] In the following embodiments shown in Figures 1 to 3, the clamping device of the present invention is described as being applied to antenna equipment, but the clamping device of the present invention can also be applied to installing lighting fixtures (not shown) such as LED lighting devices and high-power sports lighting on a pole, in addition to antenna equipment.

[0033] 1 to 3, a clamping device 1 for an antenna device according to an embodiment of the present invention may be a device for installing an antenna device 2 on a support pole 3. When the antenna device 2 is installed on the support pole 3 via the clamping device 1 for an antenna device, the clamping device 1 can rotate the antenna device 2 in the vertical and horizontal directions to adjust the direction of the antenna device 2.

[0034] The antenna device 2 may include an approximately hexahedral antenna housing (not shown in the drawing), and a printed circuit board having at least one antenna element and at least one radio signal processing unit (RU; Radio Unit) mounted thereon is provided inside the antenna housing.

[0035] The antenna element can transmit and receive radio signals, and the radio signal processor can process the radio signals. The antenna housing can be made of a heat-dissipating material such as aluminum, and the outer surface of the antenna housing can have heat-dissipating ribs formed thereon to increase the contact area with the surrounding air.

[0036] The support pillar 3 is formed of an RC bar. Of course, the support pillar 3 is not limited to the RC bar, but may include any column-shaped member on the outer periphery of which the antenna device 2 is installed via the antenna clamping device 1.

[0037] The clamping device 1 for antenna equipment according to an embodiment of the present invention may include an antenna mounting bracket 100, a mast mounting bracket 200, 400, a tilting drive unit 320, a steering drive unit 330, and at least one tilting link member 500, 600.

[0038] The antenna mounting bracket 100 is attached to the rear surface of the antenna device 2 to support the antenna device 2 .

[0039] Here, the pillar mounting brackets 200, 400 include an upper pillar mounting bracket 200 and a lower pillar mounting bracket 400, and the upper pillar mounting bracket 200 and the lower pillar mounting bracket 400 are arranged in a straight line in the longitudinal direction of the pillar 3 at a distance from each other.

[0040] More specifically, the upper column mounting bracket 200 is mounted on the column 3 and is positioned relatively higher than the lower column mounting bracket 400. The upper column mounting bracket 200 is coupled to the rear part of the steering drive unit 330 to support the steering drive unit 330 so that it can rotate horizontally.

[0041] The lower column mounting bracket 400 is disposed relatively lower than the upper column mounting bracket 200 and is attached to the column 3. The lower column mounting bracket 400 can support the lower portion of the antenna mounting bracket 100 so that it can rotate vertically and horizontally.

[0042] 4 is an exploded perspective view showing the clamping device for the antenna equipment shown in FIG. 2, FIG. 5 is an exploded perspective view showing the clamping device for the antenna equipment shown in FIG. 3, FIG. 6 is a perspective view of the tilting drive unit with the steering drive unit shown in FIG. 4 removed, FIG. 7A is an exploded perspective view from one direction of FIG. 6, showing the tilting link member separated, FIG. 7B is an exploded perspective view of the front part of FIG. 6, showing the internal configuration exposed, FIG. 8A is an exploded perspective view from another direction of FIG. 6, showing the tilting link member separated, FIG. 8B is an exploded perspective view of the rear part of FIG. 6, showing the internal configuration exposed, and FIG. 9 is a cutaway perspective view showing the inside of the tilting drive unit.

[0043] As shown in FIGS. 4 to 9, the tilting drive unit 320 can generate a drive force for tilting and rotating the antenna device 2 in the up and down directions.

[0044] The tilting drive unit 320 is coupled to the upper support mounting bracket 200 so as to be rotatable in the horizontal direction, and is provided to move integrally with the steering drive unit 330 which rotates in the horizontal direction by its own driving force.

[0045] Here, at least one tilting link member 500, 600 can include a first tilting link member 500 that is substantially related to the tilting rotation operation of the antenna device 2, and a second tilting link member 600 that connects the tilting drive unit 320 and the steering drive unit 330, as shown in Figures 4 to 9.

[0046] The first tilting link member 500 has one end connected to the top of the antenna mounting bracket 100 and the other end rotatably connected to the tilting drive unit 320, so that the antenna mounting bracket 100 can be rotated up and down by the driving force of the tilting drive unit 320.

[0047] More specifically, one end of the first tilting link member 500 is hingedly connected to the upper part of the antenna mounting bracket 100 so as to be rotatable relative to the upper part of the antenna mounting bracket 100, and the other end is fastened and connected to the tilting rotation shaft 326 of the tilting drive unit 320 so as to receive driving force from the tilting drive unit 320 and rotate the one end.

[0048] 7B, a concave-convex tilting shaft-type mating portion 326-1 is formed on the outer end of the tilting rotation shaft 326, and a link-type mating portion 500-1 that is mated with the tilting shaft-type mating portion 326-1 is formed on the other end of the first tilting link member 500. When the link-type mating portion 500-1 is mated face-to-face with the tilting shaft-type mating portion 326-1, it interferes with the first tilting link member 500 in the rotation direction, thereby transmitting the rotational force of the tilting rotation shaft 326 to the first tilting link member 500.

[0049] Here, the other end of the first tilting link member 500 is coupled via a link fastening bolt 550 in a state where the link mating portion 500-1 is mated with the tilting shaft mating portion 326-1.

[0050] The second tilting link member 600 has one end connected to the tilting drive unit 320 and the other end rotatably connected to the steering drive unit 330, allowing the tilting drive unit 320 to rotate up and down relative to the steering drive unit 330.

[0051] More specifically, one end of the second tilting link member 600 is fixed to the first tilting link member 500 so as to move in conjunction with the tilting drive unit 320 when the antenna mounting bracket 100 rotates up and down, and the other end is hingedly connected to the steering drive unit 330 so as to be rotatable relative to the steering drive unit 330.

[0052] In particular, the other end of the second tilting link member 600 is coupled to the steering drive unit 330 via a roller bearing 20 as shown in FIG.

[0053] The roller bearing 20 may include an outer ring fixed to the inside of a hole 331 of a steering housing main body 333 (described later) of the steering drive unit 330, an inner ring located inside the outer ring and into which the connecting end 600-1 of the second tilting link member 600 is recessed, and a plurality of ball bearings arranged between the outer ring and the inner ring.

[0054] The second tilting link member 600 is hingedly connected to the steering housing main body 333 using a link fastening bolt (not shown) in a state where the connecting end 600-1 is recessed into the inner ring of the roller bearing 20.

[0055] 10 is a perspective view of the steering drive unit shown in FIG. 4, FIG. 11 is an exploded perspective view showing the state of power transmission to the steering drive unit shown in FIG. 10, FIG. 12A is an exploded perspective view of the steering drive unit shown in FIG. 4, FIG. 12B is an exploded perspective view of the steering drive unit shown in FIG. 5, and FIG. 13 is a cutaway perspective view showing the inside of the steering drive unit.

[0056] As shown in Figures 4 and 5, the antenna mounting bracket 100 may include an antenna mounting bracket body 110 that is coupled to the back of the antenna device 2, and antenna mounting bracket wings 120 that are respectively formed on the antenna mounting bracket body 110 and protrude toward the support pole 3, and are coupled to one end of the first tilting link member 500 via the fixing member 10.

[0057] The antenna mounting bracket wings 120 are formed of a pair of antenna mounting bracket wings 120 spaced apart horizontally from the rear surface of the antenna mounting bracket body 110, and the first tilting link member 500 is formed of a pair of first tilting link members 500, one end of which is connected to each of the pair of antenna mounting bracket wings 120, and the other end of the pair of first tilting link members 500 is rotatably hingedly connected to both the left and right sides of the tilting drive unit 320, respectively.

[0058] Here, the fixing member 10 is provided as a hinge bearing type that supports rotation between one end of the first tilting link member 500 and the antenna mounting bracket wing 120 .

[0059] In this way, the antenna mounting bracket 100 is provided to be freely rotatable by the hinged fixing member 10, so that the upper end of the antenna mounting bracket 100 can tilt and rotate up and down along the swing trajectory of one end of the first tilting link member 500, centered on the lower end of the antenna mounting bracket 100.

[0060] In addition, the second tilting link member 600 is formed of a pair of second tilting link members 600, one end of which is connected to each side of the tilting drive unit 320, and the other end of the pair of second tilting link members 600 is rotatably hinged to each side of the steering drive unit 330 via roller bearings 20.

[0061] Here too, the other end of the second tilting link member 600 is provided by the roller bearing 20 so as to be freely rotatable relative to the steering drive unit 330, so that when the first tilting link member 500 tilts and rotates due to the transmission of driving force from the tilting drive unit 320, the tilting drive unit 320 can move along the swing trajectory of the other end of the second tilting link member 600 separately from the steering drive unit 330, and the tilting range of the antenna device 2 can be expanded within the moving range of the tilting drive unit 320.

[0062] More specifically, the tilting drive unit 320 is disposed above the steering drive unit 330 when rotated to the maximum upward position as shown in Figures 2 and 3, and is disposed below the steering drive unit 330 when rotated to the maximum downward position as shown in Figure 1. This makes it possible to maximize the tilting adjustment range of the antenna device 2.

[0063] However, the tilting drive unit 320 does not necessarily have to be configured to move lower than the steering drive unit 330, and it goes without saying that the tilting drive unit 320 can be positioned higher than the steering drive unit 330 as long as the maximum tilting angle of the antenna device 2 is secured, as shown in Figure 14 described below.

[0064] The lower pillar mounting bracket 400 may include a lower pillar mounting body 410, a lower steering part 420 rotatably connected to the lower pillar mounting body 410 in a horizontal direction, and a lower tilting part 430 rotatably connected to the lower steering part 420 in a vertical direction and connected to the lower part of the antenna mounting bracket 100.

[0065] Specifically, the antenna mounting bracket 100 is provided on the antenna device 2. The antenna mounting bracket 100 may be provided on the rear surface of the antenna device 2. The antenna mounting bracket 100 is connected to the antenna device 2 to support the antenna device 2. When the antenna mounting bracket 100 is provided on the rear surface of the antenna device 2, it is disposed so as to protrude toward the support pole 3.

[0066] The antenna mounting bracket 100 may include an antenna mounting bracket body 110 and antenna mounting bracket wings 120 .

[0067] The antenna mounting bracket body 110 is coupled to the rear surface of the antenna device 2. The antenna mounting bracket body 110 may be formed in a plate shape such that the front surface of the antenna mounting bracket body 110 contacts the rear surface of the antenna device 2.

[0068] The antenna mounting bracket body 110 is coupled to the rear surface of the antenna device 2 via a plurality of bolts and a plurality of nuts. In this case, it is preferable that the antenna mounting bracket body 110 and the rear surface of the antenna device 2 are each provided with bolt holes for fastening the bolts.

[0069] Of course, the antenna mounting bracket body 110 may be coupled to the rear surface of the antenna device 2 by various known coupling methods such as welding.

[0070] The antenna mounting bracket wings 120 may include a pair of antenna mounting bracket wings 120 that protrude rearward and are spaced apart from each other in the horizontal direction from the rear surface of the antenna mounting bracket body 110. The antenna mounting bracket wing 120 is formed in a rectangular plate shape with a convex rounded rear end. The antenna mounting bracket wing 120 is fixedly coupled to one end of the first tilting link member 500, and can rotate up and down when the first tilting link member 500 rotates up and down by the driving force of the tilting driving unit 320.

[0071] 4 to 9, the tilting drive unit 320 includes tilting housings 323 and 324, a tilting reducer 325 disposed in the tilting housings 323 and 324 and having a tilting worm gear 325a, and a tilting rotation shaft 326 disposed in the tilting housings 323 and 324 and having a tilting worm wheel gear 327 meshing with the tilting worm gear 325a on its outer periphery, disposed horizontally, and connected to the other end of the first tilting link member 500.

[0072] On both sides of the tilting housings 323 and 324, a hole 321 to which the other end of the first tilting link member 500 is rotatably coupled is formed, and a coupling portion 322 to which one end of the second tilting link member 600 is coupled is protruded.

[0073] Specifically, the tilting housings 323, 324 may include a tilting housing main body 323 that is hollow inside and has one side open, and a tilting housing cover 324 that is coupled to cover the open side of the tilting housing main body 323.

[0074] Here, the hole 321 to which the other end of the first tilting link member 500 is coupled and the coupling portion 322 to which one end of the second tilting link member 600 is coupled may pass through the closed portion on the left side of the tilting housing body 323 and the tilting housing cover 324, respectively, or may be formed on the outer surface thereof.

[0075] In particular, one end of the second tilting link member 600 is fixed to the connecting portion 322 with a plurality of assembly screws 650 in contact therewith. Therefore, when the first tilting link member 500 rotates due to the tilting driving force, the tilting driving unit 320 moves back and forth around the other end of the second tilting link member 600.

[0076] 4 and 10 to 13, the steering drive unit 330 includes steering housings 333 and 334, a steering reducer 335 disposed in the steering housings 333 and 334 and equipped with a steering worm gear 335a, and a steering rotation shaft 336 disposed in the steering housings 333 and 334, having a steering worm wheel gear 337 meshing with the steering worm gear 335a on its outer periphery, disposed vertically, and connected to the upper support mounting bracket 200.

[0077] Specifically, the steering housings 333, 334 may include a steering housing main body 333 that is hollow inside and has an open bottom, and a steering housing cover 334 that is coupled to cover the open bottom of the steering housing main body 333.

[0078] Here, as shown in Figures 12A and 12B, the rear end of the steering housing body 333 is inserted between the upper mounting panel portion 210a and the lower mounting panel portion 210b that protrude forward of the upper support pillar mounting bracket 200, and the steering rotation shaft 336 can be bolted using the shaft fixing bolt 230 through the shaft fixing hole 210h formed to penetrate the upper mounting panel portion 210a and the lower mounting panel portion 210b in the vertical direction, respectively.

[0079] The steering rotation shaft 336 is arranged vertically in the vertical direction inside the steering housing main body 333 and is configured to rotate about its axis by receiving its own driving force transmitted from the steering reducer 335, and is bolted in place using the above-mentioned shaft fixing bolt 230 with its upper and lower end surfaces mated with the mounting mold mating portions 220 formed in a concave and convex shape on the lower surface of the upper mounting panel portion 210a and the upper surface of the lower mounting panel portion 210b, respectively.

[0080] The upper and lower end surfaces of the steering rotation shaft 336 are mold-fitted to the above-mentioned mounting mold mating portion 220 and interfere with each other in the direction of shaft rotation, so that the steering drive unit 330 rotates left and right due to the rotational force of the steering rotation shaft 336 itself.

[0081] At this time, the upper and lower ends of the steering rotation shaft 336 are exposed to the upper and lower ends, respectively, through an upper through-hole 333a and a lower through-hole 333b formed by penetrating vertically at the rear end of the steering housing main body 333, and are molded into the mounting mold mating portions 220 of the upper mounting panel portion 210a and the lower mounting panel portion 210b.

[0082] Meanwhile, the steering reducer 335 may include a reduction gearbox 335b incorporating a reduction motor (not shown) and a gear set (not shown), and the steering worm gear 335a that rotates by receiving the driving force output from the reduction gearbox 335b.

[0083] Here, the steering worm gear 335a is preferably arranged horizontally inclined to the left or right side within the steering housings 333, 334 so as to minimize an increase in the volume of the rear portion, which has a relatively small volume.

[0084] Holes 331 to which the other end of the second tilting link member 600 is rotatably coupled are formed on both sides of the steering housings 333 and 334, and roller bearings 20 to which the other end of the second tilting link member 600 is freely rotatably coupled are installed in the holes 331 on both sides.

[0085] 14A and 14B are side views showing the clamping device for an antenna device according to the embodiment of the present invention before and after tilting.

[0086] In the initial state where no tilting rotation operation is performed, the front surface of the antenna device 2 is aligned vertically as shown in Fig. 14(a). At this time, the first tilting link member 500 and the second tilting link member 600 can maintain their respective vertically parallel positions.

[0087] When the tilting drive unit 320 operates for beam tilting of the antenna element, the tilting drive unit 320 is driven, and the tilting drive force is transmitted from the tilting reducer 325 to the tilting rotation axis 326, as shown in (b) of Figure 14.

[0088] In this case, one end of the first tilting link member 500 connected to the antenna mounting bracket wing 120 rotates while tracing a predetermined swing trajectory with a point T2 at the other end as the rotation center.

[0089] At this time, the antenna mounting bracket 100 tilts downward and forward by a predetermined angle around the lower end to which the upper end is fixed, and the second tilting link member 600 also rotates, tracing a predetermined swing trajectory by the distance traveled by the antenna mounting bracket 100, one end of which has tilted forward, around a point T1 at the other end hinged to the steering drive unit 330 as the rotation center.

[0090] Here, the tilting drive unit 320 also moves forward by the rotation distance of one end of the second tilting link member 600, thereby providing the advantage that a sufficient angle of tilting rotation can be achieved even with a small rotation angle of the first tilting link member 500.

[0091] As described above, the clamping device 1 for an antenna device according to the embodiment of the present invention can maximize the tilting adjustment range of the antenna device 2 via the first tilting link member 500 and the second tilting link member 600.

[0092] Those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, the above-described embodiments should be understood to be illustrative in all respects and not limiting. The scope of the present invention is defined by the claims that follow rather than the above detailed description, and all modifications and variations that fall within the meaning and scope of the claims and their equivalents should be construed as being within the scope of the present invention.
