Description

Technical Field

[0001] The present invention relates to a clamping device for a base station antenna, and more particularly to a clamping device for a base station antenna which can be used to install the base station antenna on a pole so as to smoothly perform a tilting action remotely. Background Art

[0002] In mobile communication systems, "base station" refers to a system that relays radio waves from mobile terminals within a cell. Base stations are mainly installed on the roofs of buildings, etc., and relay radio waves from portable terminals. Therefore, base stations exist in units of cells, and in addition to controlling the interface function between mobile terminals and switching centers, the base station also controls the transmission of input and output signals, the designation of call channels, and the monitoring of call channels in units of cells. For antenna devices used in base stations, steerable antennas that can tilt beams vertically or horizontally have become popular because they have many advantages.

[0003] As mobile communication services become more popular, antenna devices that provide a wireless network environment that can provide more stable services are becoming more prevalent. Mobile communication services have evolved from 2G (second-generation mobile communication technology) that was only for wired calls to 3G, 4G, and pre-5G, and are now being introduced to 5G. Antenna devices for 5G mobile communications are installed together with existing 4G and pre-5G, so they can share the same installation location.

[0004] However, the existing base station antenna device has a problem that once the installation on the pole is completed, it is difficult for the staff to approach the antenna module installed at a high place to readjust the direction of the antenna module. Summary of the invention

[0005] (Problem to be solved)

[0006] The present invention is proposed to solve the above-mentioned technical problems, and its purpose is to provide a base station antenna clamping device capable of remotely adjusting the inclination of an antenna module installed on a pole.

[0007] At the same time, another object of the present invention is to provide a clamping device for a base station antenna that is easy to set up and combine with a pole.

[0022] In addition, the lower combining fixture can be hingedly fixed to the lower end of the antenna module using the lower rotating connecting piece as an intermediate piece.

[0023] In addition, the tilting portion may be controlled by wireless or wired remote driving.

[0066] Hereinafter, embodiments of the base station antenna clamping device of the present invention will be described in detail with reference to the accompanying drawings.

[0067] When assigning reference numerals to components of the various drawings, it should be noted that the same components should have the same reference numerals as much as possible even if they are shown in different drawings. In addition, when describing the embodiments of the present invention, if it is determined that the specific description of the relevant known structure or function hinders the understanding of the embodiments of the present invention, the specific description will be omitted.

[0068] When describing the components of the embodiments of the present invention, the terms first, second, A, B, (a), (b), etc. may be used. Such terms are only used to distinguish one component from other components, and the nature or order of the components shall not be limited by the terms. In addition, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by ordinary technicians in the field to which the present invention belongs. Terms such as those defined in commonly used dictionaries should be interpreted as consistent with the meaning in the relevant technical articles and shall not be interpreted in an ideal or overly formal sense unless clearly defined in this application.

[0069] Figure 1This is a perspective view showing the front side downward of a clamping device for a base station antenna according to an embodiment of the present invention; Figure 2 This is a perspective view showing the rear side downward of a clamping device for a base station antenna according to an embodiment of the present invention; Figure 3 yes Figure 1 and Figure 2 Exploded stereogram of Figure 4 This is a side view showing the tilted state of the base station antenna clamping device according to one embodiment of the present invention.

[0070] like Figures 1 to 4 As shown, a clamping device 100 for a base station antenna according to an embodiment of the present invention includes a guide arm unit 105 and an inclined portion 101. The guide arm unit 105 guides the inclined portion 101 to move, and the inclined portion 101 can adjust the inclination angle of the antenna module A while being guided by the guide arm unit 105 to move.

[0071] Here, the antenna module A may include an antenna device having at least one frequency band (hereinafter, distinguished by the reference numeral "A1") and a repeater (RRH, remote radio head; hereinafter, referred to as "RRH", and distinguished by the reference numeral "A2"), wherein the repeater is connected to the antenna device and performs functions such as amplifying or retransmitting, shaping distorted waveforms, and retiming weak signals received between a base station of a mobile communication system and a mobile communication terminal.

[0072] like Figure 1 and Figure 2 As shown, the guide arm unit 105 can be horizontally extended to one side to be orthogonal to the vertically arranged pole 1. The pole 1 can be roughly formed into a cylindrical shape with a hollow interior. The guide arm unit 105 can be stably horizontally set on the outer peripheral surface of the pole 1 composed of such a structure using the upper joint fixture 10 and the installation fixture 30 described later as an intermediate piece.

[0073] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the pole 1 is described as being limited to being vertically configured up and down. However, although not shown in the accompanying drawings, the pole 1 can of course be horizontally configured on the wall of the house. In this case, the front end of the pole 1 horizontally configured on the wall of the house is also provided with a vertical rod not shown, which is orthogonally connected to the pole 1, and can replace the above-mentioned pole 1 vertically configured up and down on the horizontal ground. Below, for the sake of convenience of explanation, the direction-related terms used in one embodiment of the present invention are described based on the pole 1 vertically configured up and down on the horizontal ground, regardless of the actual setting direction of the pole 1.

[0074] like Figures 1 to 4As shown, the guiding arm unit 105 restricts the moving distance of the inclined portion 101 while performing the function of guiding the movement of the inclined portion 101. That is, one end of the guiding arm unit 105 is coupled to the mast 1, and the other end is disposed at a position extending a predetermined length in a cantilever form with respect to the mast 1. The movement of the inclined portion 101 can be restricted between one end and the other end of the guiding arm unit 105.

[0075] More specifically, as Figure 3 shown, the guiding arm unit 105 may include: a housing connector 120 that mediates the coupling of the guiding arm unit 105 to the mast 1; and a guiding housing 110 that is connected to the housing connector 120 and horizontally extends in a direction orthogonal to the mast 1.

[0076] Here, the guiding housing 110 may be formed in a vertical cross-section in a "C" shape with an open bottom. This is to prevent interference when the upper rotating connector 41 that mediates the coupling between the inclined portion 101 and the upper end portion of the antenna module A and the inclined portion 101 move.

[0077] On the other hand, in a state where the housing connector 120 is installed in the mounting fixture 30 that is coupled to the mast 1 described later, it performs the function of stably fixing to the mast 1 with the upper coupling fixture 10 described later as an intermediate member. The specific shape and structure of the housing connector 120 will be described in detail in the description part of the mounting fixture 30 described later.

[0078] As Figures 1 to 4 shown, the inclined portion 101 is disposed within the guiding arm unit 105, and moves the upper end portion of the antenna module A horizontally within the guiding arm unit 105 with respect to the lower end portion of the antenna module A at a fixed hinge position, and thus can perform the function of adjusting the inclination angle with respect to the mast 1.

[0079] More specifically, as Figure 3 shown, the antenna module A is rotatably connected to the inclined portion 101 with the upper rotating connector 41 disposed at the upper end portion as an intermediate member, and is rotatably connected to the mast 1 with the lower rotating connector 42 disposed at the lower end portion as an intermediate member.

[0080] Here, as Figure 3 shown, the mast 1 may be provided with an upper coupling fixture 10 and a mounting fixture 30, and may also be provided with a lower coupling fixture 20. The upper coupling fixture 10 and the mounting fixture 30 mediate the coupling between the guiding arm unit 105 disposed for inclining the upper end portion of the antenna module A and the mast 1. The lower coupling fixture 20 mediates the coupling between the mast 1 and the rotating bracket 45. The rotating bracket 45 is disposed to mediate the hinge coupling between the lower coupling fixture 20 and the lower rotating connector 42 connected to the lower end portion of the antenna module A.

[0081] The upper rotating connection member 41 is a connection in which one end portion connected to the antenna module A and the other end portion connected to the inclined portion 101 are both hingedly connected so as to be rotatable relative to the hinge; the lower rotating connection member 42 is a connection in which one end portion connected to the antenna module A is directly bolted so as not to be hingedly connected, and the other end portion connected to the rotating bracket 45 is hingedly connected so as to be rotatable relative to the hinge. Thus, it can be defined that the hinge position of the antenna module A connected to the upper rotating connection member 41 changes according to the position of the inclined portion 101 in the guide arm unit 105, but the hinge position of the antenna module A connected to the lower rotating connection member 42 is relatively fixed.

[0082] Figure 5 It is shown Figure 1 and Figure 2 A side sectional view of the inclined portion 101 in the structure; Figure 6 It is along Figure 1 The cutting stereogram taken along the AA line; Figure 7 It is shown in Figure 1 and Figure 2 A perspective view of the interior of the inclined portion of the structure with the guide housing removed; Figure 8 It is along Figure 6 A portion of the cut stereogram taken along line BB; Fig. 9 Yes Figure 5 An enlarged cross-sectional view of a portion of the image.

[0083] like Figures 5 to 9 As shown, the tilting portion 101 may include: a screw 130, which, in the structure of the guide arm unit 105, is extended in the length direction within the guide shell 110 and has an external thread formed on the outer peripheral surface; and a tilting drive portion 140, which moves along the screw 130 and is hingedly connected to the upper end portion of the antenna module A through an upper rotating connector 41.

[0084] Here, although the external thread formed on the screw 130 is not shown in detail in the drawings, it may include any one of a ball screw shape and a trapezoidal shape into which balls of a predetermined size are inserted.

[0085] The screw rod 130 can be fixed to one inner end and the other inner end of the guide housing 110 by means of fixing bolts (not shown), respectively. The guide housing 110 is extended in the horizontal direction to be perpendicular to the holding pole 1 .

[0086] like Figures 5 to 9As shown, the tilt drive unit 140 may include: a drive unit housing 141 having a predetermined space inside; a drive motor 143, which is electrically driven and configured in a motor housing 142 coupled to the drive unit housing 141; a drive gear 145, which rotates in conjunction with a rotating shaft of the drive motor 143 extending from the motor housing 142 to the drive unit housing 141 side, and has gear teeth on the outer peripheral surface; a moving gear 144, which forms an internal thread at the rotation center to penetrate the coupling screw 130, and has gear teeth on the outer peripheral surface to engage with the drive gear 145.

[0087] The driving unit housing 141 is formed with the above-mentioned predetermined space, which performs the function of setting the setting space of the driving gear 145 and the moving gear 144. Not only that, any part is combined with a pair of guide rails 150 described later, and the pair of guide rails 150 are respectively fixed on the inner side of the width direction of the guide housing 110, and the other part is combined with the upper end of the antenna device A1 in the antenna module A with the upper rotating connecting piece 41 as an intermediate piece, and then receives the guidance of the guide rail 150 through the drive of the driving motor 143, and at the same time moves the upper end of the antenna module A in the length direction (i.e., horizontal direction) on the lower side of the guide housing 110, and at the same time performs the function of adjusting the tilt angle.

[0088] The motor housing 142 is configured to form a separate space at one side of the driving portion housing 141 , and the driving motor 143 may be fixed inside the motor housing 142 so that the driving motor 143 has the rotating shaft spaced parallel to the screw 130 .

[0089] The rotating shaft of the driving motor 143 passes through the inside of the motor housing 142 and is exposed to the inside of the driving portion housing 141 , and a driving gear 145 may be configured so that the rotating shaft of the driving motor 143 is coaxially linked.

[0090] Here, if Figure 5 , Figure 7 and Figure 8 As shown, the tilt driving part 140 may further include: a driving bearing support part 147 that rotates with respect to the driving part housing 141 and supports the driving gear 145 ; and a moving bearing support part 146 that rotates with respect to the driving part housing 141 and supports the moving gear 144 .

[0091] The drive bearing support portion 147 and the moving bearing support portion 146 perform the functions of respectively rotating with respect to the drive unit housing 141 and supporting the drive gear 145 and the moving gear 144 that are rotatably disposed within the drive unit housing 141, and can each be configured as a type that intervenes with a plurality of bearing balls for reducing friction between the inner wheel in a fixed state and the outer wheel in a rotating state. Here, the inner wheels of the drive bearing support portion 147 and the moving bearing support portion 146 are respectively fixed to the drive unit housing 141, and the outer wheels of the drive bearing support portion 147 and the moving bearing support portion 146 rotate in联动 with the drive gear 145 and the moving gear 144.

[0092] On the other hand, as Figures 5 to 9 shown, the tilt drive portion 140 may further include: a pair of guide rails 150 respectively disposed on one side and the other side in the width direction of the guide arm unit 105 and extending in the length direction of the guide arm unit 105; and a pair of moving guide blocks 160 fixed to the outside of the drive unit housing 141 and respectively coupled to the pair of guide rails 150 to mediate the coupling of the drive unit housing 141 and the pair of guide rails 150.

[0093] More specifically, the pair of guide rails 150 are respectively extended in the length direction and horizontally fixed to one side and the other side in the width direction of the guide housing 110, and the guide housing 110 is extended in the length direction and horizontally disposed.

[0094] Then, the pair of moving guide blocks 160 have a vertical cross-sectional shape of a "匚" shape to surround and clamp a part of the outer side surface of the pair of guide rails 150, and can be respectively fixed to the outer surfaces on one side and the other side of the drive unit housing 141.

[0095] Here, as Figure 6 shown, a bearing insertion hole 155 is formed between the pair of guide rails 150 and the pair of moving guide blocks 160, and a plurality of bearings (not shown) are intervened to support the tilt movement therebetween.

[0096] Fig.10 is a perspective view and a partial enlarged view showing the appearance of setting a fixing jig, an upper support jig, and a lower support jig for a holding rod in the structure of Figure 1 and Figure 2 ; Fig.11a and Fig.11b is a perspective view showing the process of setting a fixing jig for a holding rod; Figures 12a to 12c is a perspective view showing the process of setting a guide fixing bracket for a holding rod.

[0097] As Figure 10 to Figure 12cAs shown, an embodiment of the clamping device 100 for the base station antenna of the present invention may also include: an upper combining clamp 10 and a lower combining clamp 20, which are combined with the holding pole 1 at a predetermined distance above and below; and an installation clamp 30, which is arranged on the lower side of the upper combining clamp 10 and installs and fixes the shell connector 120.

[0098] In addition, if Fig.10 As shown, the upper combining fixture 10 may include: upper one-side fixture blocks 11a, 11b, which are tightly attached to the outer peripheral surface of the holding pole 1 corresponding to the outer peripheral surface between the antenna modules A; upper other-side fixture blocks 12a, 12b, which are tightly attached to the outer peripheral surface of the holding pole 1 on the opposite side of the outer peripheral surface facing the upper one-side fixture blocks 11a, 11b; and at least two upper fixing screws 13, which horizontally penetrate the upper one-side fixture blocks 11a, 11b and the upper other-side fixture blocks 12a, 12b and are tightened with nuts.

[0099] For the upper one-side clamp blocks 11a, 11b, the upper other-side clamp blocks 12a, 12b, and at least two upper fixing screws 13, a single set may be configured within the limit of firmly combining the guide arm unit 105 with the holding pole 1 as an intermediate piece. In one embodiment of the present invention, two sets of upper one-side clamp blocks 11a, 11b, the upper other-side clamp blocks 12a, 12b, and at least two upper fixing screws 13 are respectively configured to firmly fix the structures at the upper and lower sides of the housing connector 120 in the structure of the guide arm unit 105.

[0100] At least two upper fixing screws 13 penetrate the upper one side clamp blocks 11a, 11b, the upper other side clamp blocks 12a, 12b and the shell connector 120 in the structure of the guide arm unit 105 from one side and the other side of the outer peripheral surface of the holding pole 1 respectively, and can then be tightened and fixed by the upper fixing nut 14.

[0101] On the other hand, Fig.10 As shown, the lower combining fixture 20 may include: a lower one-side fixture block 21, which is tightly attached to the outer peripheral surface of the holding pole 1 corresponding to the antenna module A; a lower other-side fixture block 22, which is tightly attached to the outer peripheral surface of the holding pole 1 on the opposite side of the lower one-side fixture block 21; at least two lower fixing screws 23, which horizontally penetrate the lower one-side fixture block 21 and the lower other-side fixture block 22 for nut tightening.

[0102] At least two lower fixing screws 23 penetrate the lower one side clamp block 21, the lower other side clamp block 22 and the rotating bracket 45 from one side and the other side of the outer circumferential surface of the holding pole 1 respectively, and can be tightened and fixed by the lower fixing nut 24. The rotating bracket 45 is configured to mediate the hinge connection between the lower combining clamp 20 and the lower rotating connecting piece 42 connected to the lower end of the antenna module A.

[0103] like Figure 10 to Figure 12c As shown, the mounting fixture 30 includes: an inner mounting fixture 30a, which is tightly combined with the outer peripheral surface of the pole 1 corresponding to the antenna module A; and an outer mounting fixture 30b, which is tightly combined with the outer peripheral surface of the pole 1 on the opposite side of the inner mounting fixture 30a; wherein the inner mounting fixture 30a and the outer mounting fixture 30b can be combined with the outer peripheral surface of the pole 1 by fixing screws and fixing nuts not shown to completely surround the outer peripheral surface of the pole 1, wherein the fixing screws pass through the screw through holes 33 formed on the flange surfaces 31' contacting each surface, and the fixing nuts are fastened to the ends of the fixing screws.

[0104] Here, if Fig.11a and Fig.11b As shown, the mounting fixture 30 can be configured to include a pole coupling portion 31 and a mounting flange portion 32, wherein the pole coupling portion 31 is tightly coupled to the outer peripheral surface of the pole 1, and the mounting flange portion 32 is radially bent and extended orthogonally at the upper portion of the pole coupling portion 31 and the shell connector 120 is mounted.

[0105] Although not shown in the drawings, the inner side surface of the pole coupling part 31 may be made of a material that increases the friction force with the pole 1, or may be formed into a sawtooth shape that generates friction force. Thus, when the fixing force generated by the fixing screw and the fixing nut (not shown) is transmitted, the inner side surface of the pole coupling part 31 is tightly attached to the outer peripheral surface of the pole 1, thereby preventing the pole from sliding downward due to its own weight.

[0106] The mounting jig 30 may perform a role of stably clamping and fixing the housing connector 120 in the structure of the guide arm unit 105 .

[0107] In more detail, refer to Figure 3 (or, Fig.12a and Figure 12b ), in the structure of the guide arm unit 105, the housing connector 120 may include: a vertical portion 121, which is vertically arranged and is combined with one end of the guide housing 110 on the side of the pole 1 in surface contact; a horizontal portion 122, which surrounds the outer peripheral surface of the pole 1 from the lower end of the vertical portion 121 and is in surface contact with the upper surface of the mounting flange portion 32; and a clamping portion 125, which is bent at the front end of the horizontal portion 122 to be clamped in the frame of the mounting flange portion 32. At the same time, the housing connector 120 may also include a reinforcing portion 123, which is configured as a whole in a shape that connects the two ends of the vertical portion 121 and the horizontal portion 122 respectively.

[0108] Here, if Figure 3 (or, Fig.12a and Figure 12b) As shown, a cutting portion 124 can be formed in the outer shell connector 120. The cutting portion 124 is generally formed in a "U" shape having an inner diameter larger than the outer diameter of the mast 1. Thus, when assembled to the mast 1, the engaging portion 125 can move from the side of the outer peripheral surface of the mast 1 where the antenna module A is located, and enter the front end of the mounting flange portion 32 of the mounting jig 30 located on the opposite side of the outer peripheral surface of the mast 1 and be caught.

[0109] The cutting portion 124 is formed to open in the opposite side direction in the outer peripheral surface of the mast 1. A pair of engaging portions 125 are respectively formed at the front end portion of the cutting portion 124, and can be bent to have a substantially "匚" shaped vertical cross-sectional shape, thereby forming a card slot thicker than the thickness of the mounting flange portion in the structure of the mounting jig 30.

[0110] Refer to Figures 11a to 12c , and the process of fixing and assembling the guide arm unit 105 to the mast 1 will be briefly described as follows.

[0111] First, as Fig.11a and Fig.11b shown, in the structure of the mounting jig 30, the inner mounting jig 30a and the outer mounting jig 30b are respectively closely attached to the outer peripheral surface of the side of the outer peripheral surface of the mast 1 where the antenna module A is disposed and the outer peripheral surface of the opposite side of this side. Then, the inner mounting jig 30a and the outer mounting jig 30b are firmly fixed to the mast 1 by fixing screws and fixing nuts (not shown) passing through the through holes 33.

[0112] Then, as Fig.12a shown, in the structure of the guide arm unit 105, the outer shell connector 120 is moved from the side of the outer peripheral surface of the mast 1 where the antenna module A or the guide housing 110 is disposed to the opposite side outer peripheral surface direction of this side, that is, in the horizontal direction (refer to Fig.12a the reference numeral ① in the figure). At this time, the outer shell connector 120 can be horizontally moved so that the inner end of the "U" shape formed in the cutting portion 124 surrounds a part of the outer peripheral surface of the mast 1. At the same time, preferably, the outer shell connector 120 can be horizontally moved to a position where at least the engaging portion 125 can be caught on the front end of the mounting flange portion 32 in the structure of the mounting jig 30.

[0113] Then, as Figure 12b and Fig.12c shown, the outer shell connector 120 is moved downward (refer to ( Fig.12a the reference numeral ② in the figure)), and then the outer shell connector 120 is moved in the horizontal direction where the antenna module A or the guide housing 110 is disposed so that the front end of the mounting flange portion is caught in the card slot (not labeled) formed in the engaging portion 125 of the outer shell connector 120 (refer to Fig.12a the reference numeral ③ in the figure).

[0114] Then, if Fig.12c As shown, the guide housing 110 is combined with the housing connector 120 using an upper combining fixture 10 , at least two upper fixing screws 13 and an upper fixing nut 14 , so as to complete the assembly of the guide arm unit 105 on the pole 1 .

[0115] Fig.13 It is a side view showing various installation examples of the clamp device for base station antenna of the present invention.

[0116] Fig.13 (a) is to pass Figures 1 to 12c The installation mode of the inclined portion 101 of the base station antenna clamp device 100 according to one embodiment of the present invention is schematically described.

[0117] That is, refer to Fig.13 The clamping device 100 for a base station antenna of one embodiment of the present invention (a) is implemented by extending a guide arm unit 105 in a horizontal direction to be orthogonal to the holding pole 1, and the tilting portion 101 moves along the horizontally extending guide arm unit 105 while adjusting the tilt angle of the antenna module A.

[0118] However, the embodiment of the present invention need not be implemented as the above-mentioned embodiment, but Fig.13 As shown in (b), the guide arm unit 105 can also be configured to be vertically extended in the vertical direction to be parallel to the holding pole 1, and the tilting portion 101 can adjust the tilt angle of the antenna module A while moving along the vertically extended guide arm unit 105.

[0119] The embodiment of the antenna device for a base station of the present invention constructed as described above is that, in particular, the tilting portion 101 can be controlled by wireless or wired remote drive, so the staff does not need to directly climb the pole 1 set at a high place to adjust the direction of the antenna module A, but can adjust the direction of the antenna module A from a remote distance such as a remote support center (not shown), thereby providing the advantage of greatly improving the convenience of the staff and the reliability of the product.

[0120] The embodiments of the base station antenna device of the present invention are described in detail with reference to the accompanying drawings. However, the embodiments of the present invention are not necessarily limited to the above embodiments, but a person skilled in the art with ordinary knowledge in the technical field to which the present invention belongs can certainly make various modifications and implement them within the same scope. Therefore, the actual protection scope of the present invention should be defined by the scope of the claims.
