Description

Technical Field

[0001] The present invention relates to a clamping apparatus for an antenna, and more particularly, to a clamping apparatus for an antenna which can not only effectively arrange a plurality of antenna devices in a dense space but also easily adjust the direction of each antenna device. Background Art

[0002] Wireless communication technology, such as Multiple Input Multiple Output (MIMO) technology, is a technology that uses multiple antennas to greatly improve data transmission capacity, and is a spatial multiplexing technology in which a transmitter transmits different data through each transmitting antenna, and a receiver classifies the transmitted data through appropriate signal processing.

[0003] Therefore, as the number of transmit / receive antennas increases simultaneously, the channel capacity increases, so that more data can be transmitted. For example, if the number of antennas increases to 10, approximately 10 times the channel capacity can be secured using the same frequency band compared to the current single-antenna system.

[0004] 4G LTE-advanced uses up to 8 antennas, and products equipped with 64 or 128 antennas are currently being developed in the pre-5G stage. In 5G, base station equipment with a larger number of antennas is expected to be used, which is called massive multiple-input multiple-output (Massive MIMO) technology. Although the current cell operation is 2-Dimension, it is also called full-dimensional multiple-input multiple-output (FD-MIMO (Full Dimension)) because after the introduction of massive multiple-input multiple-output technology, 3D-Beamforming technology becomes possible.

[0005] In the massive MIMO technology, as the number of ANTs (antennas) increases, the number of transmitters and filters also increases. However, due to the rental cost or space limitations of the installation site, it has become a reality that RF components (antennas / filters / power amplifiers / transceivers, etc.) are small, light, and low-priced. However, massive MIMO requires high output to expand coverage, and the power consumption and heat generated by this high output become disadvantages for reducing weight and size.

[0006] In particular, when a MIMO antenna in which multiple modules realized by multiple RF devices and multiple digital devices are coupled in a stacked structure is arranged in a limited space, in order to maximize the convenience of arrangement or spatial applicability, there is a demand for compact and miniaturized design of the multiple layers constituting the MIMO antenna, and there is a strong demand for free directional adjustment of the antenna device arranged on a support pole. Summary of the invention

Figure 6a and Figure 6bIt is a perspective view showing a coupling state of a tilting unit and a rotating unit in the structure of the antenna holding device according to the present invention.

[0072] like Figure 1 As shown, an embodiment of the clamping device for an antenna according to the present invention includes: an arm unit 100, coupled to the support rod 1; a universal coupling unit 200, coupled to the arm unit 100; a rotating unit 300, coupled in a manner that can rotate in the left and right directions relative to the universal coupling unit 200; and a tilting unit 400, coupled to the rotating unit 300 in a manner that can tilt and rotate along the up and down directions, and the antenna device A is coupled thereto.

[0073] The arm unit 100 performs a function for mediating coupling of the antenna device A and the supporting pole 1 .

[0074] like Figure 2 As shown in parts (a) and (b) of FIG. 1 , the arm unit 100 can be connected in the form of a single beam extending in a horizontal direction orthogonal to one (i.e., a single) support rod 1. Preferably, a single clamping portion 60 formed by a tilting unit 400 and a rotating unit 300 is provided in one arm unit 100.

[0075] However, in the embodiment of the present invention, it is not necessary to provide only a single gripping portion 60 in a single arm unit 100. Figure 2 As shown in part (b) of FIG. 1 , the arm unit 100 may be branched by means of a branch frame 70 so that a clamping portion 60a, 60b including a tilting unit 400 and a rotating unit 300 is connected to each end. In this case, the arm unit 100 and the branch frame 70 may have an approximately "T" shape.

[0076] And, if Figure 2 As shown in part (c) of the embodiment of the antenna clamping device of the present invention, two or more arm units 100a, 100b, 100c may be radially arranged relative to a single support rod 1, and a single clamping portion 60a, 60b, 60c may be installed at the end of each arm unit 100a, 100b, 100c. To this end, a central bracket 80 for mediating the arrangement of multiple arm units 100a, 100b, 100c may also be provided at the center of the single support rod 1. Each arm unit 100a, 100b, 100c may be arranged at a different height of the single support rod 1, and as shown in FIG. Figure 2 As shown in part (c) of the drawings, they can also be set at the same height.

[0077] like Figure 3a and Figure 3bAs shown, the antenna clamping device of one embodiment of the present invention constructed in the above-described manner can be installed by inserting the antenna device A from the upper side to the lower side and locking it in the tilting unit 400 provided in the clamping part 60 provided at the front end of each arm unit 100. This is to improve the installation operability of the heavy antenna device A usually on site. The specific installation state of the tilting unit 400 of the antenna device A will be described in detail in the process of describing each structure of the clamping part 60 described later.

[0078] like Figure 4a As shown, such an arm unit 100 may include: an arm body 110 extending from a support rod 1 to one side in a horizontal direction by a predetermined length; a fixed bracket 120 integrally provided at one end of the arm body 110 and the other end corresponding to the support rod 1 side, and closely attached to and coupled to one side of the outer peripheral surface of the support rod 1; and a separate bracket 130 coupled to the fixed bracket 120 by a plurality of fixed long bolts 140, and closely attached to and coupled to the other side of the outer peripheral surface of the support rod 1. The ends of the plurality of fixed long bolts 140 may be mutually nut-coupled by a plurality of fixing nuts 150 provided on the separate bracket 130.

[0079] A plurality of reinforcing ribs 115 for reinforcing the rigidity of the coupling portion with the fixed bracket 120 may be integrally formed at the other end of the arm body 110. The arm body 110 and the fixed bracket 120 may be integrally injection molded from a metal material. However, the method is not limited to injection molding, and the arm body 110 and the fixed bracket 120 may also be manufactured separately and coupled by welding or the like.

[0080] On the other hand, the arm body 110 and the fixed bracket 120 can be made of metal material in one piece through a mold, and the separate bracket 130 can also be made of metal material through a mold different from the arm body 110 and the fixed bracket 120.

[0081] As described above, in the arm unit 100, the fixed bracket 120 and the separated bracket 130 are coupled by bolt coupling, and can be formed into a single beam form as follows: extending a specified length along a horizontal direction orthogonal to the length direction of the support rod 1, and the antenna device A is set in a manner separated from the support rod 1 by a specified length.

[0082] As described later, the front end portion of the arm body 110 in the arm unit 100 may be preferentially coupled to the universal coupling unit 200 so as to mediate the coupling of the clamping portion 60 manufactured in various specifications. However, according to an embodiment, the rotation unit 300 may be directly provided at the front end portion of the arm body 110 without mediating the universal coupling unit 200 (for this embodiment, it will be described later by referring to Figure 8 and Fig. 9 to be described in detail).

[0083] In the following, the description is based on the premise that the rotation unit 300 is provided at the front end of the arm body 110 of the arm unit 100 by means of the universal coupling unit 200. The universal coupling unit 200 described later is provided in a form basically similar to the rotation unit 300, but when it is fixed to the front end of the arm body 110 or the antenna device A needs to be further rotated in the left and right directions, it can have a rotatable structure similar to the rotation unit 300.

[0084] like Figures 4a to 4c As shown, the universal coupling unit 200 may include: a universal one-end coupling part 201, which is used to provide a coupling part for coupling the rotating unit 300 at one end; and a universal other-end coupling part 202, which extends from the upper end of the universal one-end coupling part 201 to the other side by a predetermined length, and a coupling shaft 210 as a coupling element shaft extends downward by a predetermined length. The coupling shaft 210 may be provided in the form of a boss that is inserted into the shaft insertion hole 191 of the fixed shaft hole block 190 described later and supported, or in the form of a long bolt that is inserted through the shaft insertion hole 191 of the fixed shaft hole block 190 and bolted, or in the form of a combination of a boss and a long bolt.

[0085] A rotation angle adjustment unit 230 described later may be built inside the universal one-end coupling unit 201 of the universal coupling unit 200. This will be described in more detail later.

[0086] A fixed shaft hole block 190 for coupling the universal coupling unit 200 may be provided at the front end of the arm body 110 of the arm unit 100. The fixed shaft hole block 190 not only performs the function of mediating the coupling of the universal coupling unit 200, but also, as another embodiment, mediates the direct coupling of the rotation unit 300. The embodiment of mediating the direct coupling of the rotation unit 300 will be described in more detail later.

[0087] In more detail, the arm body 110 has a quadrangular tube shape with a hollow interior, and the front end of the arm body 110 is open toward one side (ie, the direction where the antenna device A is located), and the upper and lower ends are protruding in semicircular shapes.

[0088] A fixed shaft hole block 190 may be inserted and fixed to the open front end of the arm body 110, and the fixed shaft hole block 190 has a shape corresponding to the empty front end internal space 160 of the arm body 110. The fixed shaft hole block 190 corresponds to the empty front end internal space 160 of the arm body 110, and one end side of the fixed shaft hole block 190 is cylindrical with a nearly semicircular horizontal cross section, and the other end side may be in a quadrangular block shape.

[0089] The fixed shaft hole block 190 may be provided with a shaft insertion hole 191 for axially setting the coupling shaft 210 of the universal coupling unit 200 from the upper part to the lower part. At the same time, a shaft through hole 165 may be formed on the upper side of the front end portion of the arm body 110 so that the coupling shaft 210 of the universal coupling unit 200 can pass through and be inserted into the shaft insertion hole 191 formed in the fixed shaft hole block 190.

[0090] The coupling shaft 210 may be coupled to the shaft insertion hole 191 by forced insertion, screw coupling, or bolt coupling.

[0091] On the other hand, a braking portion 170 ′, 170 ″ for generating a predetermined friction force with the universal coupling unit 200 may be provided at the front end portion of the arm body 110 of the arm unit 100 .

[0092] The braking part 170', 170" may include: an upper brake pad 170', 170a, 175a, which is arranged on the upper side of the front end portion of the arm unit 100, and is used to form a friction force with the upper mating surface of the universal coupling unit 200; and a lower brake pad 170", 170b, 175b, which is arranged on the lower side of the front end portion of the arm body 110 of the arm unit 100, and is used to form a friction force with the lower mating surface of the universal coupling unit 200.

[0093] like Figure 4b and Figure 4c As shown, the upper brake pads 170', 170a, 175a and the lower brake pads 170", 170b, 175b may include: fixed disc portions 170a, 170b, fixed to the upper and lower sides of the front end portion of the arm body 110 of the arm unit 100, for providing a friction surface; and rotating disc portions 175a, 175b, fixed to the upper or lower side of the universal coupling unit 200, for forming friction with the fixed disc portions 170a, 170b while rotating.

[0094] Among them, Figure 4b and Figure 4c As shown, the fixed disk portion 170a of the upper brake pads 170', 170a, and 175a is fixed to the upper side of the front end portion of the arm body 110 of the arm unit 100, and the rotating disk portion 175a of the upper brake pads 170', 170a, and 175a is arranged to be fixed to the circumferential surface of the coupling shaft 210 and rotate together with the universal coupling unit 200 as the bottom of the universal other end coupling portion 202 at the rear end portion of the universal coupling unit 200, so that as described above, when the universal coupling unit 200 needs to be further rotated and rotated, a specified friction force can be generated.

[0095] And, if Figure 4b and Figure 4cAs shown, the lower brake pads 170", 170b, 175b are connected to the bottom of the rear end portion of the rotating unit 300, and can be set by means of a washer setting bracket 180 extending from the lower end portion of the universal one-end coupling portion 201 of the universal coupling unit 200 to the other end side and extending to the lower side surface of the front end portion of the arm body 110.

[0096] Similarly, the rotating disk portion 175b is arranged on the top of the washer setting bracket 180, and the fixed disk portion 170b is fixed on the lower side of the front end portion of the arm body 110 of the arm unit 100, so that as described above, when the universal coupling unit 200 needs to be further rotated and rotated, a specified friction force is formed.

[0097] The above describes the case where the universal coupling unit 200 is fixed to the front end of the arm body 110 of the arm unit 100 for mediation, so that even if the clamping part 60 described later is set to have different shapes with various specifications, its assembly versatility can be achieved.

[0098] However, the rotation unit 300 described later may be directly provided at the front end of the arm body 110 in a manner that it can rotate and turn by means of the fixed shaft hole block 190 instead of the universal coupling unit 200. In this case, as a result of removing the universal coupling unit 200, preferably, the rotation angle adjustment unit 230 designed to be built into the universal one-end coupling unit 201 of the universal coupling unit 200 is also removed. In addition, it is also possible to directly provide the rotation angle adjustment unit 230 inside the fixed shaft hole block 190 instead of removing the rotation angle adjustment unit 230.

[0099] Except for the above-mentioned removed structure, each structure of the rotating unit 300 coupled to the front end portion of the arm body 110 of the arm unit 100 is coupled in the same manner as the fixed shaft hole block 190 of the universal coupling unit 200 .

[0100] On the other hand, Figure 4b and Figure 4c As shown, the clamping portion 60 is provided in a rotatable or tiltable manner so that the directivity of the antenna device A can be set while mediating the installation of the antenna device A.

[0101] In more detail, the clamping portion 60 may include a rotating unit 300 coupled to the front end portion of the arm body 110 of the arm unit 100 , and a tilting unit 400 coupled to the rotating unit 300 .

[0102] like Figure 1 to Figure 2 As shown, the antenna device A is detachably provided on the tilt unit 400 .

The coupling unit cover 207 supports the rotation of the lower end of the rotating shaft 231 facing the upper end where the shaft hole 231' is formed, and since the above-mentioned washer setting bracket 180 is separately provided, it can be coupled or integrally formed.

[0128] Figure 8 A perspective view showing another embodiment of the antenna clamping device according to the present invention, Fig. 9 for Figure 8 Exploded three-dimensional diagram.

[0129] Reference Figures 1 to 7 An embodiment of the antenna holding device according to the present invention described below is an embodiment implemented as a rotating unit 300 in a structure in which the holding portion 60 is provided through the universal coupling unit 200 .

[0130] However, refer to Figure 8 and Fig. 9 Another embodiment of the antenna clamping device according to the present invention is the following embodiment: the universal coupling unit 200 is not provided, and the rotating unit 300 of the clamping part 60 is directly provided in a rotatable manner on the fixed axis hole block 190 provided at the front end of the arm body 110 of the arm unit 100.

[0131] However, in another embodiment of the antenna holding device according to the present invention, the universal coupling unit 200 is removed, and the structure of the rotation angle adjustment unit 230 built into the universal coupling unit 200 to rotate the rotation unit 300 in the left and right directions can also be removed. That is, this embodiment can be defined as an embodiment in which only the tilt angle adjustment unit 330 built into the rotation unit 300 is left as a common element among the rotation angle adjustment unit 230 and the tilt angle adjustment unit 330.

[0132] All other structures are replaced by the aforementioned description of the structure of an embodiment of the present invention and their coupling relationships.

[0133] Fig.10a and Fig.10b A system diagram showing a remote control system according to an embodiment of the antenna holding device of the present invention.

[0134] In the embodiment of the antenna clamping device according to the present invention, the tilting and rotating of the tilting unit 400 and the rotating and rotating of the rotating unit 300 can be directly driven by the on-site installation personnel to set the directivity of the antenna device A.

[0135] However, if Fig.10a As shown, the tilting and rotating of the tilting unit 400 and the rotating and rotating of the rotating unit 300 can be remotely controlled by the maintenance unit (O&M) 40 through a control unit (not shown) arranged inside the antenna device A and a distribution unit (DU) 30 for mediating their remote connection. The above-mentioned antenna device A is connected to the tilting unit 400 and the rotating unit 300 in a manner capable of electrical communication.

[0136] The control unit, the tilting unit 400 and the rotating unit 300 of the antenna device A are connected via a communication cable 21 , and the control unit and the distribution unit 30 of the antenna device A can be communicatively connected via an optical cable 23 .

[0137] And, if Fig.10b As shown, the tilting and rotating of the tilting unit 400 and the rotating and rotating of the rotating unit 300 can be remotely controlled by a remote controller (Remote controller ler) 35. The remote controller is wired to be able to communicate with each adjustment part of the tilting unit 400 and the rotating unit 300 (that is, the tilting angle adjustment part 330 of the tilting unit 400 and the rotation angle adjustment part 230 of the rotating unit 300), and can be disassembled and assembled with a communication cable 21 arranged near the clamping part 60 (preferably the support rod 1).

[0138] Among them, the remote controller 35 is formed into a size that can be carried by on-site setting personnel. After the setting of the clamping part 60 of the antenna device A is completed, the directivity of the antenna device A can be remotely controlled by coupling to the terminal of the communication cable 21 to match the frequency characteristics of the setting area.

[0139] Therefore, refer to Fig.10a and Fig.10b , the on-site setup personnel can directly use the remote controller 35 to perform the directional work of the antenna device A, and the maintenance department 40 can calculate the frequency characteristics and perform remote control, thereby providing the advantage of greatly improving operability.
