Description

Technical Field

[0001] The present invention relates to a clamping apparatus for an electronic device, an antenna apparatus including the same, and a lighting apparatus (CLAMPING APPARATUS FOR ELECTRONIC DEVICE, ANTENNA APPARATUS AND LIGHTNING APPARATUS INCLUDING THE SAME). More specifically, the present invention relates to a clamping apparatus for an electronic device that enables an operator to efficiently arrange an electronic device in a crowded installation space, is easy to adjust the direction of the electronic device, can minimize interference during direction adjustment according to the size of the electronic device, and is very easy to attach to a support pole, an antenna apparatus including the same, and a lighting apparatus.

Background Art

[0002] Generally, wireless communication technology, for example, MIMO (Multiple Input Multiple Output) technology is a technology that epochally increases data transmission capacity using multiple antennas. In a transmitter, different data is transmitted via each transmission antenna, and in a receiver, it is a Spatial multiplexing method that differentiates transmitted data by appropriate signal processing.

[0003] In Massive MIMO technology, as the number of ANTs (antennas) increases, the number of transmitters and filters also increases accordingly. In particular, when installing a MIMO antenna in which modules with RF elements and digital elements realized are combined in a stacked structure in a limited space, in order to maximize the ease of installation and space utilization, the need for compactification and miniaturization design for multiple layers constituting the MIMO antenna emerges, and the need for free direction adjustment of an antenna apparatus installed on one support pole is strongly demanded at present.

[0004] In response to the aforementioned requirements, the Registered Patent Publication of the Republic of Korea No. 10-2095871 (published April 2, 2020) (hereinafter referred to as "prior art") discloses an "antenna clamping device" comprising 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.

[0005] However, the aforementioned conventional technology has the problem that the range of vertical rotation of the tilting unit is small. When the tilting rotation range is small, it not only fails to cover the area immediately below the building on which it is installed, but it also leads to problems such as having to tilt the support pole or having to tilt the antenna equipment from the beginning.

[0006] Furthermore, it has been pointed out that the installation of relatively heavy antenna equipment onto support poles requires a very complex process, which makes it difficult to ensure the safety of workers on site.

[0007] In addition, conventional antenna clamping devices, as their name suggests, are specialized in adjusting the directionality of antenna equipment, and therefore their core components consist only of technical configurations related to coupling and fixing to antenna equipment. However, equipment requiring directionality adjustment includes not only the aforementioned antenna equipment but also lighting fixtures, laser oscillators, air conditioning equipment, etc., and there is a problem in that the usability of conventional clamping devices specialized for antenna equipment is extremely limited.

[Modes for carrying out the invention]

[0046] Hereinafter, a clamping device for electronic equipment, an antenna device including the same, and a lighting device according to embodiments of the present invention will be described in detail with reference to the attached drawings.

[0047] When assigning reference numerals to the components in each drawing, it should be noted that, as far as possible, identical components should have the same reference numeral even if they are shown in other drawings. Furthermore, when describing embodiments of the present invention, if it is determined that a specific description of such known configurations or functions would hinder understanding of the embodiments of the present invention, such detailed description will be omitted.

[0048] In describing the components of the embodiments of the present invention, terms such as First, Second, A, B, (a), (b), etc., may be used. Such terms are merely for distinguishing a component from other components, and do not limit the nature, order, or procedure of that component. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention pertains. Terms as defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and not in an ideal or overly formal sense unless explicitly defined in this application.

[0049] Figure 1 is a perspective view showing the installation of electronic equipment on a support pole using an electronic equipment clamping device according to one embodiment of the present invention; Figure 2 is an exploded perspective view showing an example of an antenna device and a lighting device among the electronic equipment including the electronic equipment clamping device according to one embodiment of the present invention; Figure 3 is a perspective view of the configuration in Figure 1 with the electronic equipment removed; and Figure 4 is an exploded perspective view showing the configuration in Figure 3 with the steering housing and tilting bracket separated.

[0050] As shown in Figures 1 to 4, one embodiment of the present invention, a clamping device 1 for electronic equipment, mediates the installation of electronic equipment A on a support pole P, and simultaneously performs a function that enables detailed directional settings to satisfy the directional design of various oscillation elements generated via the electronic equipment A on a fixed support pole P (for example, beamforming of the frequency beam emitted from the electronic equipment A when it is used as an antenna device).

[0051] For reference, the electronic equipment A whose directionality is expected to be adjusted by the clamping devices 1 and 1A according to embodiments of the present invention is not limited to the antenna equipment A-1 shown in Figure 2(a), but can include any electronic equipment A whose directionality of an oscillating element is required to be adjusted by electrical operation, such as the lighting device A-2 shown in Figure 2(b), laser oscillator, and air conditioning equipment.

[0052] However, since the applicant of the present invention primarily engages in the manufacture and sale of antenna equipment among electronic devices A that requires directional adjustment, the following description will assume that the antenna device A-1 among the aforementioned electronic devices is to be applied. However, this should not be interpreted as limiting the scope of the rights of the present invention to clamping devices 1 and 1A applied to antenna device A-1.

[0053] Therefore, all terms described below, including "antenna device A-1" or "antenna" and "lighting device A-2" or "lighting," must be broadly interpreted as "electronic equipment" or "device."

[0054] Hereinafter, when an electronic clamping device according to one embodiment of the present invention is applied to antenna equipment, it will be defined as "antenna equipment 1, A-1 including electronic clamping device," and when an electronic clamping device according to one embodiment of the present invention is applied to lighting equipment, it will be defined as "lighting equipment 1, A-2 including electronic clamping device" and described accordingly.

[0055] More specifically, as shown in Figures 1 to 4, the clamping device 1 for electronic equipment according to one embodiment of the present invention can be connected horizontally at a predetermined distance apart, so that it is provided in a substantially cantilever shape in a direction perpendicular to the longitudinal direction of the vertically mounted support pole P, via an upper fixing bracket portion 50A and a lower fixing bracket portion 50B that are pre-provided near the outer surface of the support pole P.

[0058] In addition, in the case of the lighting device A-2 including the clamping device 1 for electronic equipment according to one embodiment of the present invention, the steering unit 100 plays the role of being able to steer left and right relative to the guide housing 70A to adjust the irradiation angle of light from the irradiation surface of the LED element A-25 mounted on the LED substrate A-22 in the left and right direction, as shown in Figure 2(b), and the tilting unit 200 plays the role of being able to tilt forward and backward relative to the steering unit 100 to adjust the irradiation angle of light from the LED element A-25 in the up and down direction, via the installation of the lighting body A-21 through the tilting bracket portion 200B.

[0065] Here, the guide housing 70A, as will be described later, plays the role of providing a steering drive unit installation space 100S in which the steering drive unit 100A of the steering unit 100 is housed, and at the same time, by being integrally equipped with the upper support pole clamping end 75A, it can also play the role of mediating the connection to the support pole P together with the upper fixing bracket portion 50A and the lower fixing bracket portion 50B.

[0066] Similarly, as will be described later, the steering rotation guide bracket portion 70B plays a role in supporting the left-right steering rotation movement of the steering housing 100H as part of the steering unit 100's configuration. At the same time, by being integrally equipped with the lower support pole clamping end 75B, it can also mediate the connection to the support pole P together with the upper fixing bracket portion 50A and the lower fixing bracket portion 50B.

[0067] On the other hand, the steering unit 100, as shown in Figures 1 to 4, may include a steering drive unit 100A concealed inside the guide housing 70A, a steering shaft 140 that rotates with respect to a vertically positioned pivot axis (see the drawing reference numeral "SC" in Figure 7, described later) by the rotational force provided by the steering drive unit 100A, and a steering housing 100H connected to the steering shaft 140, which conceals the tilting drive unit 200A of the tilting unit 200 (described later) inside and rotates in the left-right direction between the guide housing 70A and the steering rotation guide bracket portion 70B.

[0069] Figures 5A and 5B are exploded perspective views showing the lower and upper views illustrating the installation structure of the steering housing and tilting bracket section to the guide housing and steering rotation guide bracket section, respectively, as shown in Figure 3. Figures 6A and 6B are exploded perspective views showing the front and rear views illustrating the installation structure of the upper and lower fixing bracket sections to the support pole, respectively, as shown in Figure 3.

[0070] As shown in Figures 5A and 5B, the upper fixing bracket portion 50A and the lower fixing bracket portion 50B are arranged in close contact with a pair of connecting bars 52 so that the bracket body 51 surrounds one side of the support pole P (in one embodiment of the present invention, the rear outer peripheral surface). The upper support pole clamping end 75A of the guide housing 70A is then placed in close contact with the upper side of the other side of the support pole P (in one embodiment of the present invention, the front outer peripheral surface), and then they are connected to each other using stud fixing bolts 54.

[0071] Here, the bracket body 51 of the upper fixing bracket portion 50A may have a pair of clamping gear panels 57a and 57b provided in the gear mounting grooves 55a and 55b.

[0072] Each pair of clamping gear panels 57a and 57b has pin through-holes 58a and 58b formed therein, for fastening with a single fixing pin 56. The single fixing pin 56 passes through both the gear panel fixing hole 59, which is formed to penetrate the bracket body 51 vertically, and the pin through-holes 58a and 58b simultaneously, allowing the two clamping gear panels 57a and 57b to be fixed to the gear mounting grooves 55a and 55b at the same time.

[0073] In addition, a pair of gear mounting grooves 77A-a, 77A-b, and 77B-a, 77B-b may be formed on the upper support pole clamping end 75A of the guide housing 70A and the lower support pole clamping end 75B of the steering rotation guide bracket portion 70B, for which a pair of clamping gear panels 79A-a, 79A-b and 79B-a, 79B-b are provided.

[0074] Here, locking grooves (see 81A-a, etc.) are formed in the intermediate portions of each clamping gear panel 79A-a to 79B-b, into which the heads of the fastening screws 80A-a, 80A-b and 80B-a, 80B-b are locked. As the fastening screws 80A-a, 80A-b and 80B-a, 80B-b are fastened into the screw fastening holes (see 78A-a, etc.), their heads are locked into the locking grooves (see 81A-a, etc.), thereby fixing each clamping gear panel 79A-a to 79B-b to the gear mounting grooves 77A-a, 77A-b and 77B-a, 77B-b, respectively.

[0075] On the other hand, the upper support pole clamping end 75A of the guide housing 70A and the lower support pole clamping end 75B of the steering rotation guide bracket portion 70B can be connected via upper and lower stud fixing poles 60A and 60B so as to firmly maintain a separation distance between them in the vertical direction.

[0076] More specifically, bolt connecting bosses 75A-B and 75B-B are formed on the upper support pole clamping end 75A and the lower support pole clamping end 75B, respectively, and the upper and lower ends of the upper and lower stud fixing poles 60A and 60B are firmly fastened to the bolt connecting bosses 75A-B and 75B-B, respectively, thereby enabling a four-point connection between the guide housing 70A and the steering rotation guide bracket portion 70B.

[0077] However, the fastening of the upper and lower stud fixing poles 60A and 60B may be performed during the process of fixing the steering housing 100H between the guide housing 70A and the steering rotation guide bracket portion 70B.

[0078] Although not shown in the diagram, the lower ends of the upper and lower stud fixing poles 60A and 60B may also be further fixed by stud fixing bolts that pass through bolt connecting bosses 75B-B formed on the lower support pole clamping end 75B from bottom to top.

[0079] On the other hand, as shown in Figures 5A and 5B, the steering rotation guide bracket portion 70B may include a horizontal bracket panel 71B that integrally forms the lower support pole clamping end 75B described above and rotatably supports the lower surface of the steering housing 100H.

[0080] A steering guide projection 73B may be formed at the front end of the horizontal bracket panel 71B, protruding upward. The steering guide projection 73B can be integrally formed with a steering rotation guide boss 100H-B on the lower surface of the steering housing 100H, into which the steering guide projection 73B is inserted, so as to perform the same function as the steering rotation axis SC.

[0081] Therefore, when the steering housing 100H is steered in the left-right direction by the drive of the steering drive unit 100A located inside the guide housing 70A, the upper end of the steering housing 100H rotates with respect to the shaft connecting portion 100H-C which is aligned with the lower end of the steering shaft 140, and the lower end of the steering housing 100H rotates with respect to the steering rotation guide boss 100H-B described above, thereby enabling stable steering rotation.

[0082] Figure 7 shows a perspective view (a) and a plan view (b) of the configuration in Figure 3 in which left-right steering movement is realized by the steering unit, and Figure 8 shows a perspective view (a) and a side view (b) of the configuration in Figure 3 in which up-down tilting movement is realized by the tilting unit.

[0083] When an electronic device A is mounted on a tilting bracket portion 200B via a clamping device 1 for electronic equipment according to one embodiment of the present invention, the steering rotation operation and tilting rotation operation of the steering unit 100 and the tilting unit 200, respectively, allow the orientation for optimizing the directional design of the electronic device A (particularly, if the electronic device A is an antenna device A-1, the beamforming emitted from it) to be set, as shown in Figures 7 and 8.

[0084] More specifically, as shown in Figure 7, the steering housing 100H is concealed inside the guide housing 70A, and the steering drive unit 100A is used to rotate the guide housing 70A and the steering rotation guide bracket 70B in the left-right direction within a predetermined angular range, thereby adjusting the left-right direction of the electronic device A.

[0085] Furthermore, as shown in Figure 8, the tilting bracket portion 200B can be rotated within a predetermined angular range in the vertical direction with respect to the tilting rotation axes TC on the left and right sides of the steering housing 100H using a tilting drive unit 200A concealed inside the steering housing 100H, thereby adjusting the vertical direction of the electronic device A.

[0086] Figures 9A and 9B are exploded perspective views from below and above to illustrate the installation structure of the steering drive unit relative to the guide housing in the configuration of Figure 3, Figures 10A and 10B are exploded perspective views from the front and rear to illustrate the detailed configuration of the steering drive unit in the configuration of Figure 3, and Figure 11 is a plan view to illustrate the arrangement of the steering shaft and reduction gear set relative to the guide housing.

[0087] In one embodiment of the present invention, in a clamping device 1 for electronic equipment, and in antenna devices 1, A-1 and lighting devices 1, A-2 including the same, as shown in Figures 9A to 11, the steering unit 100 may include a steering drive unit 100A concealed inside the guide housing 70A and a steering shaft 140 vertically arranged in the vertical direction inside the guide housing 70A.

[0088] Here, the steering drive unit 100A may include a steering drive motor 110 having a motor shaft 110C that is electrically rotated and provided inside the guide housing 70A, and a reduction gear set 120 that is connected to the motor shaft 110C of the steering drive motor 110, receives rotational force, and reduces the gear ratio by a predetermined gear ratio.

[0089] The reduction gear set 120 may include a gear fixing panel 121 provided via motor mounting brackets 123 and 124, and a gearbox housing 122 and gear set 130 coupled to the gear fixing panel 121.

[0090] Multiple screw fastening holes 121h are formed in the gear fixing panel 121, and multiple screw through holes 122h are also formed in the gearbox housing 122. By fastening multiple fastening screws 125 through each screw fastening hole 121h and screw through hole 122h, a portion of the gear set 130 can be installed inside the gearbox housing 122.

[0091] On the other hand, the output worm gear 137 of the gear set 130 may be exposed and mounted on the outside of the gearbox housing 122. The output worm gear 137 receives rotational force reduced by the other gear components of the gear set 130 and acts as a transmission gear that transmits it to the steering shaft 140.

[0092] Here, the gear set 130 may include a first worm gear 131 that rotates connected to the motor shaft 110C of the steering drive motor 110, as shown in Figure 10, and first reduction gears 132 to fifth reduction gears 136 that are arranged sequentially from the first worm gear 131 and reduce the gear ratio by meshing with it.

[0093] The fifth reduction gear 136 is provided so as to be directly connected to the rotation axis of the output worm gear 137, and can rotate the output worm gear 137 in the axial direction. The worm gear teeth provided on the outer circumference of the output worm gear 137 mesh with the pinion gear portion 141 of the steering shaft 140, thereby rotating the steering shaft 140 in the axial direction.

[0094] Here, the output worm gear 137, including the fifth reduction gear 136, may be arranged horizontally in the guide housing 70A and alternately at predetermined angles with respect to the axial direction (e.g., the tilting rotation axis TC) of the tilting shaft 240 of the tilting unit 200, which will be described later.

[0095] In this way, the axial directions of the output worm gear 137 and the tilting shaft 240 are arranged alternately at predetermined angles to each other. This has the advantage that, even when the weight of electronic equipment A, such as the antenna device A-1, affects the steering housing 100H during the tilting operation of the tilting bracket 200B, a decrease in the meshing force between the worm gear teeth of the output worm gear 137 and the pinion gear portion 141 of the steering shaft 140 can be prevented. Therefore, even when the electronic equipment A shakes due to external forces (for example, strong winds), the stability of the steering rotation operation can be ensured.

[0096] On the other hand, the guide housing 70A may include a lower guide housing 71A with an upper support clamping end 75A integrally formed thereon, as shown in Figures 9A and 9B, and an upper guide housing 72A that covers the upper part of the lower guide housing 71A and provides an installation space 100S for the steering drive unit 100A inside.

[0097] The upper guide housing 72A has a shaft mounting groove 73A that protrudes upward, on which the upper end portion 143 of the steering shaft 140 is placed, and a motor mounting groove 74A can be formed that protrudes upward so that the steering drive motor 110 can be housed inside.

[0098] The upper end 143 of the steering shaft 140 may be rotatably mounted in the shaft mounting groove 73A, while being rotatably supported via a shaft support bearing 151.

[0099] On the other hand, the lower guide housing 71A may have a shaft through-hole 71A-h formed therein, through which the motor mounting brackets 123 and 124 are firmly fixed as described above, and through which the lower end of the steering shaft 140 passes and allows for alignment coupling to a shaft connecting portion 100H-C integrally provided on the upper surface of the steering housing 100H.

[0100] In other words, the lower end of the steering shaft 140 has multiple cam interference surfaces (not indicated in the drawing reference numerals) that rotate in the direction of axial rotation with the shaft connecting portion 100H-C, and can be rotatably connected by an action that aligns the shaft connecting portion 100H-C, which is integrally provided on the upper surface of the steering housing 100H, through the shaft through hole 71A-h. At this time, multiple rotation support bearings 153 may be interposed at the inner circumference end of the shaft through hole 71A-h to rotatably support the steering shaft 140.

[0101] In addition, an O-ring 155 is provided near the edge of the shaft through-hole 71A-h to prevent rainwater from entering the interior.

[0102] The shaft connecting portion 100H-C, which is integrally provided on the upper surface of the steering housing 100H, may be configured to receive the rotational force of the steering drive unit 100A and play a role in rotating the steering housing 100H itself in the left-right direction with respect to the steering pivot axis SC.

[0103] Figures 12A and 12B are exploded perspective views of the front and rear sections illustrating the mounting structure of the tilting drive unit to the steering housing as shown in Figure 3; Figures 13A and 13B are exploded perspective views of the front and rear sections illustrating the detailed configuration of the tilting drive unit as shown in Figure 3; and Figure 14 is a perspective view illustrating the coupling of the reduction gear set to the tilting shaft as part of the tilting drive unit configuration.

[0104] In one embodiment of the present invention, in an electronic device clamping device 1, and in antenna devices 1, A-1 and lighting devices 1, A-2 including the same, as shown in Figures 12A to 14, the tilting unit 200 may include a tilting drive unit 200A concealed inside the steering housing 100H and a tilting shaft 240 horizontally arranged in the left-right direction inside the steering housing 100H.

[0105] Here, the tilting drive unit 200A may include a tilting drive motor 210 located inside the steering housing 100H and having an electrically rotationally driven motor shaft (not shown), and a reduction gear set 220 connected to the motor shaft of the tilting drive motor 210 to receive rotational force and reduce speed by a predetermined gear ratio.

[0106] The reduction gear set 220 may include a gear set 230 provided via motor mounting brackets 221 and 222.

[0107] On the other hand, the motor shaft of the tilting drive motor 210 is rotatably connected to the motor mounting brackets 221 and 222, and the output worm gear 237 of the gear set 230 may be arranged vertically in the vertical direction. The output worm gear 237 acts as a transmission gear that receives rotational force reduced by the other gear components of the gear set 230 and transmits it to the tilting shaft 240.

[0108] Here, the gear set 230 may include a first worm gear 231 that is connected to and rotates on the motor shaft of the tilting drive motor 210, as shown in Figure 14, and first reduction gears 232 to fifth reduction gears 236 that are arranged sequentially from the first worm gear 231 and reduce the gear ratio by meshing with it.

[0109] The fifth reduction gear 236 is provided so as to be directly connected to the rotation axis of the output worm gear 237, and can rotate the output worm gear 237 in the axial direction. The worm gear teeth provided on the outer circumference of the output worm gear 237 mesh with the pinion gear portion 241 of the tilting shaft 240, thereby rotating the tilting shaft 240 in the axial direction.

[0110] On the other hand, the steering housing 100H may include a housing body 100H-1 having an opening on either the left or right side, forming an installation space 200S inside which the tilting drive unit 200A can be concealed, as shown in Figures 12A to 13B, and a housing cover 100H-2 which is coupled to the housing body 100H-1 so as to shield the open side.

[0111] The housing body 100H-1 and the housing cover 100H-2 may each have shaft through-holes 100H-2h formed therein, which expose one end and the other end of a tilting shaft 240 that is horizontally positioned in the left-right direction within the installation space 200S.

[0112] Furthermore, a power connector (see "100H-G" in Figure 5) may be provided protruding downwards from the lower part of the housing body 100H-1 of the steering housing 100H.

[0113] Here, as described above, the steering housing 100H is provided so as to be rotatable in the left-right direction between the guide housing 70A and the steering rotation guide bracket portion 70B. Therefore, the steering rotation guide bracket portion 70B may be provided with interference avoidance holes 71B-G that pass through in the vertical direction to avoid interference with the power connector 100H-G of the steering housing 100H.

[0114] More specifically, the interference avoidance holes 71B-G may be provided in a shape similar to the trajectory of the rotation radius of the power connector 100H-G when the steering housing 100H performs a steering rotation operation.

[0115] Thus, since the power connector 100H-G rotates within a predetermined trajectory via the interference avoidance hole 71B-G with respect to the steering rotation guide boss 100H-B, it can also effectively play an additional role in guiding the left and right steering rotation of the steering housing 100H.

[0116] On the other hand, the installation space 200S of the steering housing 100H may also be further equipped with a control board 270, which is supplied with power by the aforementioned power connector 100H-G, as shown in Figures 12A to 13B, and controls the operation of the steering drive motor 110 of the steering drive unit 100A and the tilting drive motor 210 of the tilting drive unit 200A.

[0117] In addition, the tilting bracket portion 200B may include, as shown in Figures 12A to 13B, a device mounting portion 201B to which the back of the electronic device A is coupled to the front, and a pair of tilting mounting portions 203B-1 and 203B-2 that extend rearward from the back of the device mounting portion 201B so as to overlap the left and right sides of the steering housing 100H, with tilting axis protrusions 205B-1 and 205B-2 integrally formed thereon.

[0118] Here, at least one of the pair of tilting mounting parts 203B-1 and 203B-2 (in one embodiment of the present invention, this corresponds to 203B-2) may be provided detachably from the equipment mounting part 201B so that the tilting shaft projections 205B-1 and 205B-2 are inserted in the left-right direction into the shaft alignment grooves 245C-1 and 245C-2 of the tilting shaft 240 fixed inside the steering housing 100H.

[0119] In other words, the tilting shaft projections 205B-1 and 205B-2 provided on the tilting mounting parts 203B-1 and 203B-2 must be inserted through the shaft through-hole 100H-2h inside the steering housing 100H, and then inserted into the shaft-shaped alignment grooves 245C-1 and 245C-2 formed at both ends of the tilting shaft 240, respectively, in order to enable smooth assembly without interference with the steering housing 100H.

[0120] According to one embodiment of the present invention, which has the above configuration, the clamping device 1 for electronic equipment, and the antenna device 1, A-1 and lighting device 1, A-2 including it, the steering rotation guide boss 100H-B formed at the lower part of the steering housing 100H is hinged to the steering guide projection 73B formed on the steering rotation guide bracket portion 70B. This allows the steering housing 100H to be easily mounted on the steering rotation guide bracket portion 70B and connected to the support pole P, thereby ensuring the safety of workers on site.

[0121] Furthermore, in one embodiment of the present invention, the clamping device 1 for electronic equipment, and the antenna devices 1, A-1 and lighting devices 1, A-2 including the same, can prevent expansion of the overall size of the product in the vertical or front-to-back direction, thereby improving the ability to install in narrow spaces. This is achieved by concealing the steering drive unit 100A inside the guide housing 70A and concealing the tilting drive unit 200A inside the steering housing 100H.

[0122] On the other hand, multiple antenna coupling holes 201B-1h for bolt connection to electronic device A can be formed through each corner end of the equipment mounting portion 201B in the front-to-back direction.

[0123] Figures 15A and 15B are downward and upward perspective views showing a clamping device for electronic equipment according to another embodiment of the present invention; Figures 16A and 16B are exploded perspective views of Figures 15A and 15B; Figures 17A and 17B are one-way and other-way exploded perspective views showing the steering unit of the clamping device for electronic equipment according to another embodiment of the present invention; and Figures 18A and 18B are downward and upward exploded perspective views showing the tilting unit of the clamping device for electronic equipment according to another embodiment of the present invention.

[0124] Hereinafter, a clamping device 1A for electronic equipment according to another embodiment of the present invention, and antenna devices 1A, A-1 and lighting devices 1A, A-2 including the same, will be described with reference to the attached drawings.

[0125] However, since the clamping device 1 for electronic equipment according to one embodiment of the present invention, which has already been described, and the antenna devices 1, A-1 and lighting devices 1, A-2 including it, have the same configuration and function, a specific redundant explanation will be omitted. Instead, the newly added or modified configurations in the clamping device 1A for electronic equipment according to another embodiment of the present invention, and the antenna devices 1A, A-1 and lighting devices 1A, A-2 including it will be described in detail.

[0126] Firstly, referring to Figures 15A and 15B, the upper fixing bracket portion 1050A and the lower fixing bracket portion 1050B, which are pre-provided near the outer circumferential surface of the support pole P, differ from the above-described embodiment (1) in that a pair of clamping gear panels 1057a and 1057b are not provided separately, and a part of the bracket body 1051 is integrally formed in a cut-out manner.

[0127] Furthermore, in the case of the clamping device 1 for electronic equipment according to one embodiment of the present invention, and the antenna device 1, A-1 and lighting device 1, A-2 including the same, as shown in Figures 6A and 6B, the stud fixing bolts 54 pass through the connecting bar fastening ends 53, which are provided in a boss shape at both ends of the bracket body 51, and are fastened to a pair of connecting bars 52. The pair of connecting bars 52 each extend from the connecting bar fastening ends 53 of the upper fixing bracket portion 50A and the lower fixing bracket portion 50B toward the guide housing 70A and the steering rotation guide bracket portion 70B, and are provided in a manner in which their tips are inserted into bolt fastening holes 75A-h and 75B-h formed at both ends of the upper support pole clamping end 75A and the lower support pole clamping end 75B.

[0128] In contrast, the clamping device for electronic equipment 1A according to other embodiments of the present invention, and the antenna devices 1A, A-1 and lighting devices 1A, A-2 including the same, differ in that, as shown in Figures 16A and 16B, the pair of connecting bar fastening ends 1053 are simply provided in a panel shape with through holes 1053h, and the stud fixing bolts 1054 are provided so as to pass directly through the through holes 1053h of the pair of connecting bar fastening ends 1053 from the rear without the provision of a pair of connecting bars 52, and fasten to bolt fastening holes 1075A-h and 1075B-h formed at both ends of the upper support pole clamping end 1075A and lower support pole clamping end 1075B of the guide housing 1070A and steering rotation guide bracket portion 1070B.

[0129] Secondly, in the clamping device 1A for electronic equipment according to another embodiment of the present invention, and in the antenna devices 1A, A-1 and lighting devices 1A, A-2 including the same, the tilting bracket portion 1200B may be formed by integrally bending a pair of tilting mounting portions 1203B-1 and 1203B-2 backward relative to the equipment mounting portion 1201B, as shown in Figures 16A and 16B.

[0130] This differs from the case of the clamping device 1 for electronic equipment according to one embodiment of the present invention described above, and the antenna device 1, A-1 and lighting device 1, A-2 including it, in that tilting shaft protrusions 205B-1 and 205B-2 are integrally formed on the mutually opposing inner surfaces of the pair of tilting mounting parts 203B-1 and 203B-2, which are aligned with the shaft alignment grooves 245C-1 and 245C-2 of the tilting shaft 240, and one of the pair of tilting mounting parts 203B-1 and 203B-2 (203B-2) is separately provided.

[0131] Here, the clamping device 1 for electronic equipment according to one embodiment of the present invention, and the antenna devices 1, A-1 and lighting devices 1, A-2 including it, are fixed by an operation in which a separately provided tilting mounting portion 203B-2 moves in the axial direction of the tilting shaft 240 so that the shaft alignment groove 245C-2 and the tilting shaft projection 205B-2 are aligned, and then fastened using fixing bolts (not shown) to the mounting fastening holes 203B-2h formed at the front end of the tilting mounting portion 203B-2 via mounting bolt holes 201B-2h formed in the equipment mounting portion 201B.

[0132] However, in the case of the clamping device 1 for electronic equipment according to one embodiment of the present invention, and the antenna device 1, A-1 and lighting device 1, A-2 including it, the fixing force for fixing the tilting mounting part 203B-2 depends solely on fixing bolts arranged in a straight line in the vertical direction, which means there is a possibility of shaking (play) or damage due to external forces in the lateral direction (left and right direction).

[0133] Therefore, in the clamping device 1A for electronic equipment according to another embodiment of the present invention, and the antenna devices 1A, A-1 and lighting devices 1A, A-2 including the same, both have a pair of tilting mounting parts 1203B-1 and 1203B-2 integrally formed with respect to the equipment mounting part 1201B, and a tilting shaft connecting part 1246, which includes a configuration corresponding to the tilting shaft protrusions 205B-1 and 205B-2 of one embodiment (1) of the present invention (see reference numeral "1249" in Figure 18A), is provided separately from the tilting mounting parts 1203B-1 and 1203B-2 in a panel shape, and the pair of tilting mounting parts 1203B-1 and 1203B-2 can be bolted to the outer surface of the tilting shaft connecting part 1246 using a plurality of fixing bolts 1204B.

[0134] The tilting shaft connecting portion 1246, having this configuration, is connected to the tilting shaft projection 1249 by moving from the outside to the inside of the steering housing 1100H, so that it aligns with the shaft alignment grooves 1245C-1 and 1245C-2 provided at both ends of the tilting shaft 1240, respectively. It can then be firmly fixed by shaft connecting bolts (not shown) that are fastened through shaft connecting holes (not shown in the drawing) formed by passing through the tilting shaft projection 1249.

[0135] In this way, after the tilting shaft connecting parts 1246 are fixed to both the left and right ends of the tilting shaft 1240, the tilting mounting parts 1203B-1 and 1203B-2, which are integrally formed with the equipment mounting part 1201B, are moved to the rear where the steering housing 1100H is located, and the fixing bolt fastening holes 1248 formed in the tilting shaft connecting part 1246 and the fixing bolt through holes 1203B-4 formed in the tilting mounting parts 1203B-1 and 1203B-2 are moved so that they match each other, and then the bolting is completed using multiple fixing bolts 1204B, thereby enabling the connection work to be performed without interference with the steering housing 1100H.

[0136] For reference, the steering housing 1100H may include a housing body 1100H-1 and a housing cover 1100H-2 that shields one open side of the housing body 1100H-1, similar to the clamping device 1 for electronic equipment according to one embodiment of the present invention, and the antenna device 1, A-1 and lighting device 1, A-2 which include the same.

[0137] Here, a shaft through-hole 1100H-h may be formed in the closed side of the housing body 1100H-1 and the housing cover 1100H-2, communicating with the tilting shaft projection 1249 of the tilting shaft connecting portion 1246 described above so as to be inserted into the inside of the installation space 200S.

[0138] A rotational support bearing 1248A can be interposed on the inner circumferential surface of the shaft through-hole 1100H-h to rotate and support the end of the tilting shaft 1240, to which the tilting shaft projection 1249 is fitted (joined).

[0139] On the other hand, a tilt angle display section 1247 for displaying the tilt angle is formed on the outer surface of the tilting shaft connecting section 1246, protruding outward, and a display section housing groove 1203B-3 for housing the tilt angle display section 1247 may be cut out at the rear ends of the pair of tilting mounting sections 1203B-1 and 1203B-2 so as not to interfere with the tilt angle display section 1247.

[0140] A tilt angle printing section 1100H-1a may be printed on the steering housing 1100H so that the user can measure the tilt angle using the indicator line of the tilt angle display section 1247 described above.
