An inclination-angle adjusting device and an Mt element and an Alt element included in the antenna TECHNICAL FIELD

The present invention relates to an inclination angle adjusting device for adjusting an inclination angle of an antenna using a rotational force while easily coupling a remote control device, and a MET element and a RET element included therein. In particular, protrusions are formed on an outer circumferential surface of the MET element and an inner circumferential surface of the RET element so that the remote control device inserted into the MET element can stably provide the force to the MET element even when an external force is applied to the tilt angle adjusting device.

The first tilt angle adjusting device includes a MET element 100 as shown in FIG. 1 and a RET element (not shown) housing the same.

Referring to FIG. 1, the MET element 100 includes a force transmission member 102, a body 104, and a drive member 106.

When the user rotates the driving member 106 by hand, the force transmitting member 102 linearly moves in response to the rotation, and as a result, an RF to which a phase shifter (not shown) connected to the force transmitting member 102 is input. The inclination angle is adjusted by varying the phase of the signal. Here, the screw thread 108 is formed in the force transmission member 102, and corresponds to the screw thread 108 inside the drive member 106 to move the force transmission member 102 in accordance with the operation of the drive member 106. A structure (not shown) is formed.

In the MET element 100 having such a structure, the driving member 106 could be moved by external force such as vibration, shock, etc. even though the user did not rotate the driving member 106. Therefore, the MET device 100 couples the cap 110 to the driving member 106 to fix the driving member 106 when the inclination angle is not adjusted in order to prevent such a movement phenomenon.

In addition, in order to rotate the drive member 106 using a remote control device such as a motor, the cap 110 had to be removed first, and then the remote control device had to be coupled to the drive member 106. Therefore, there was an inconvenience of separating the cap 100, there was a fear that the separated cap 110 is lost.

However, if the MET element 200 was to be controlled using a remote control device, the force transmission member fixing members and the drive member 206 had to be separated before installing the remote control device. As a result, the force transmission member fixing members and the driving member 206 have to go through an inconvenient process of fastening or detaching, and the force transmission member fixing members and the driving member 206 thus separated may be lost. .

It is to provide a tilt angle adjustment device formed and the MET element and RET element included therein. In detail, the MET protrusion is formed on the outer circumferential surface of the MET element, and the RET protrusion is formed on the inner circumferential surface of the RET element facing the MET protrusion.

In order to achieve the above object, the tilt angle adjusting device of the antenna according to an embodiment of the present invention includes a MET element having a MET body; And a RET element housing the MET element. Here, a first protrusion is arranged on a portion of the MET body of the MET element, and an inner surface between the first protrusion and the RET element is closely arranged.

3 is a perspective view illustrating an inclination angle adjusting device according to an embodiment of the present invention. Specifically, Figure 3 (A) is a perspective view showing a MET element of the tilt angle adjustment device according to an embodiment of the present invention, Figure 3 (B) is a RET element of the tilt angle adjustment device according to an embodiment of the present invention 3 (C) is a cross-sectional view showing a coupling form between the MET element and the RET element.

The inclination angle adjusting device of this embodiment is a device for adjusting the inclination angle of the antenna, and is shown in FIG. 3 (B) housing the MET element 300 and the MET element 300 as shown in FIG. 3 (A). RET element 302 as shown.

Hereinafter, a combination form of the MET element 300, the RET element 302, the MET element 300 and the RET element 302 will be described in detail.

First, the structure and operation of the MET element 300 will be described in detail.

Referring to FIG. 3A, the MET element 300 is connected to a phase shifter to transmit a specific rotational force to the phase shifter as described below, and the phase shifter is input from the outside according to the rotational force. The phase of the RF signal is changed to change the direction of the beam output from the antenna. Details thereof will be described later.

The MET element 300 includes a force transmission member 304, a MET body 306, a drive member 308, and a display member 314.

The force transmission member 304 is connected to the phase shifter and transmits the rotational force according to the rotation of the driving member 308 to the phase shifter. Here, although the connection between the force transmission member 304 and the phase shifter is not shown, the connection relationship may be variously modified as long as the force transmission member 304 may transmit rotational force to the phase shifter.

The MET body 306 houses the force transmission member 304 to protect the force transmission member 304, and a portion thereof, preferably corresponding to the display member 314, is marked with a scale indicating the degree of tilt angle adjustment. Can be.

In addition, a protrusion 316 is formed on the outer circumferential surface of the MET body 306, preferably, an outer circumferential surface end portion thereof, and a thread 318 is formed on the other end portion of the outer circumferential surface thereof. The function of these protrusions 316 and threads 318 will be described later.

The driving member 308 corresponds to a handle portion that can be grasped by a user among the MET elements 300, and has a rotatable structure on the MET body 306 as shown in the following drawings.

In addition, a protrusion is coupled to the force transmission member 304 in the driving member 308 as described later. Thus, when the user or the remote control device rotates the drive member 308, the drive member 308 rotates on the MET body 306, so that the rotational force due to the rotation of the drive member 308 is transmitted through the protrusion. Is transmitted to the force transmission member 304. Here, the remote control device is a device for rotating the drive member 308, for example, may be an electric motor, that is, a motor.

An insertion portion 312 is formed on the outer surface of the driving member 308, preferably the front surface, as shown in FIG. 3A. Here, the remote control device is inserted into the insertion portion 312, and rotates the drive member 308 in the inserted state. According to one embodiment of the invention, the insertion portion 312 of the drive member 308 may have a polygonal shape so that the force of the remote control device is well transmitted.

In addition, the driving member 308 has a cylindrical shape as shown in Fig. 3 (A), the anti-slip protrusion 310 to prevent the user's hand from slipping when the user rotates the driving member 308 by hand It may be formed on the outer peripheral surface thereof.

The display member 314 is a member for indicating the degree of adjustment of the inclination angle, and its position is moved in response to the rotation of the drive member 308. In this case, the user may check the moving position of the display member 314 through the scale displayed on the MET body 306 to determine the degree of inclination adjustment. For the operation of the display member 314, a thread is formed on a portion of the force transmission member 304 as shown in FIGS. 3 and 8, and the force transmission member 304 is formed on an inner surface of the display member 314. A screw thread corresponding to the thread of () may be formed.

In short, the MET element 300 of the present embodiment rotates the driving member 308 to generate a rotational force, and transmits the generated rotational force to the phase shifter through the force transmission member 304 to adjust the inclination angle of the antenna. .

In particular, since the remote control device is directly coupled to the drive member 308 without removing some components of the MET element 300, the MET element 300 of the present embodiment is easier to remotely control than the conventional MET element. The devices can be combined and disconnected. In addition, since the remote control device does not remove any components when combined with the drive member 308, unlike the conventional MET elements, there is no fear that the components of the MET element 300 are lost.

Next, the configuration of the RET element 302 and the coupling form of the MET element 300 and the RET element 302 will be described.

Referring to FIG. 3B, the RET element 302 is a device for housing the MET element 300 to protect the MET element 300, and includes a RET body 320, a RET shell 322, and a remote control. Device fixing portion 324 and engagement member 326.

The RET shell 322 is coupled to the RET body 320 and the coupling member 326, and is coupled to the thread 318 formed on the outer circumferential surface of the MET body 306 as shown in FIG. 3C.

The remote control device fixture 324 is coupled with the RET body 320 and secures the remote control device 330, for example an electric motor. Specifically, the remote control device 330 is fixed to the remote control device fixing part 324 through a fastening member 332 such as a bolt. In this case, the rotation axis of the remote control device 330 is inserted into the insertion portion 312 of the drive member 308 as shown in Fig. 3C. That is, the remote control device 330 is inserted into the insertion portion 312 of the MET element 300 in a fixed state by the RET element 302, and then rotates the drive member 308 if necessary.

Referring to part A of FIG. 3C, a MET protrusion 316 is formed on an outer circumferential surface of the MET body 306, and a RET protrusion 328 facing the MET protrusion 316 on an inner circumferential surface of the RET body 320. Is formed. According to one embodiment of the invention, the MET protrusion 316 is formed along the outer peripheral surface of the cylindrical MET body 306, the RET protrusion 328 is formed around the inner surface of the cylindrical RET body 320 Therefore, the MET protrusion 316 and the RET protrusion 328 may be arranged in close contact with each other. For example, the MET protrusion 316 and the RET protrusion 328 may be in close contact such that the distance between the MET protrusion 316 and the RET protrusion 328 is about 0.1 mm to about 0.15 mm. Therefore, even when an external force 340 is applied to the tilt angle adjusting device, the RET element 302 is hardly inclined due to the protrusions 316 and 328, so that the RET element 302 is fixed to the RET element 302 and inserted into the insert portion. The rotation axis of the remote control device 330 inserted into 312 is also not inclined. Therefore, the rotation axis of the remote control device 330 can rotate within the error range but less than the number of times input by the user in the insertion portion 312, and as a result, the rotational force of the remote control device 330 is driven It can be well delivered to the member 308. A detailed description thereof will be given through the experimental results described below.

Hereinafter, the phase shifter coupled to the MET element 300 having the above-described structure to adjust the phase of the signal will be described briefly.

4 is a diagram illustrating an upper portion of a phase shifter according to an embodiment of the present invention, and FIG. 5 is a perspective view illustrating a lower portion of the phase shifter of FIG. 4. 6 is a schematic cross-sectional view of the phase shifter of FIGS. 4 and 5.

4 and 5, the phase shifter of the present embodiment includes a dielectric substrate 400, a first line 402, a second line 404, an input line 406, and an output line 408. , A rotation shaft 410, an arm section 412, a guide member 414, a first rotation member 500, and a second rotation member 502. As shown in FIG. 6, the phase shifter is connected to the lower rotating members 500 and 502 and the upper members 400, 412 and 414 through the rotation shaft 410.

Hereinafter, the operation of the components of the phase shifter having such a structure will be described.

The dielectric substrate 400 is made of a dielectric material having a predetermined dielectric constant, and a ground plate is formed on the bottom surface or the inside of the dielectric substrate 400.

The first line 402 is formed on the dielectric substrate 400 as a conductor, for example, in a curved shape. Here, terminations of the first line 402 are electrically connected to some of the radiation elements (not shown) (eg, first and second radiation elements), although not shown.

The second line 404 is formed on the dielectric substrate 400 as a conductor, for example, with a curved shape, the ends of which are electrically connected to some of the radiation elements (eg, third and fourth radiation elements). Connected.

Input line 406 receives the RF signal as a conductor. Some of the RF signals thus received are output to the corresponding radiation element through the first dielectric substrate region positioned below the output line 408 without changing the phase, and the remaining RF signals are coupled at the rotation axis 410. And then output to the corresponding radiating elements through the second dielectric substrate region positioned below the arm portion 412. As a result, the array antenna of the radiating elements has a predetermined beam pattern, and the beam pattern is changed in response to the phase change of the RF signal along the movement path of the RF signal.

The second rotating member 502 couples with the force transmitting member 304 of the MET element 300 and rotates in response to the rotational force transmitted from the force transmitting member 304.

The first rotating member 500 rotates in response to the rotation of the second rotating member 502. According to one embodiment of the invention, the second rotating member 500 is a gear worm and the first rotating member 502 is a gear wheel.

The rotating shaft 410 is connected to the first rotating member 500 at the bottom of the phase shifter, and is connected to the arm 412 and the guide member 414 at the top of the phase shifter. The rotation shaft 410 rotates in accordance with the rotation of the rotation members 500 and 502, and as a result, the arm 412 and the guide member 414 rotate in response to the rotation of the rotation shaft 410.

As illustrated in FIG. 6, the guide member 414 is connected to the rotary shaft 410 and the arm 412 to transmit a force according to the rotation of the rotary shaft 410 to the arm 412. As a result, the arm portion 412 is rotated with the guide member 414 by the transmitted force.

In other words, the phase shifter is connected to the MET element 300 and changes the phase of the input RF signal in response to the rotational force transmitted from the MET element 300. As a result, the direction of the beam radiated from the antenna is varied. That is, the MET element 300 of the present invention provides a rotational force to the phase shifter to adjust the inclination angle of the antenna.

The phase shifter of the present invention may be variously modified as long as it has a structure using the rotational force provided from the MET element 300, and is not limited to the structure of FIGS. 4 to 6.

Hereinafter, the structure of the MET device 300 will be described in more detail.

7 is a perspective view illustrating a MET device in a fixed state.

Referring to FIG. 7, the MET body 306 has a cylindrical groove 700 and at least one incomplete cylindrical groove 702.

When the driving member 308 is coupled to the cylindrical groove 700 as shown in FIG. 3, the driving member 308 may rotate on the cylindrical groove 700 due to the characteristics of the cylindrical groove 700. On the other hand, when the driving member 308 is coupled to the incomplete cylindrical groove 702 as shown in FIG. 7, the incomplete cylindrical groove 702 cannot be rotated due to the characteristics of the incomplete cylindrical groove 702. Is fixed to. Although not shown in FIG. 7, at least one hook member is formed inside the driving member 308, and the driving member 308 is engaged with the MET body 306 by the hook member being caught by the incomplete cylindrical groove 702. It is fixed to). As a result, the drive member 308 can be stably fixed to the MET body 306 even if an external force such as an impact occurs.

That is, the user places the hook member of the driving member 308 in the cylindrical groove 700 and then rotates the driving member 308 to transmit a specific rotational force to the phase shifter, and as a result, the inclination angle of the antenna can be adjusted. . Then, the user places the hook member of the driving member 308 in the incomplete cylindrical groove 702 by pulling the driving member 308 so that the driving member 308 is not rotated by an external force. ). Subsequently, if the user wants to adjust the inclination angle again, a force is applied to the drive member 308 so that the drive member 308 is located in the cylindrical groove 700.

In other words, unlike the conventional MET element which fixed the drive member using a separate member, the MET element 300 of the present embodiment fixes and rotates the drive member 308 by a simple method of pushing and pulling the drive member 308. Let's do it. That is, the MET element 300 does not require a separate member for fixing the driving member 308.

8 is an exploded perspective view of a MET device according to an embodiment of the present invention.

Referring to FIG. 8, the MET element 300 of the present embodiment further includes fixing members 802, 804, and 806 in addition to the force transmission member 304, the MET body 306, and the driving member 308.

A protrusion 800 is formed in the driving member 308 as shown in FIG. 8, and an insertion portion 808 into which the protrusion 800 can be inserted is formed at the end of the force transmission member 304. . That is, when the MET element 300 is coupled, the driving member 308 is coupled to the force transmission member 304 by inserting the protrusion 800 into the insertion portion 808. Here, according to one embodiment of the present invention, the projection 800 has a polygonal shape so that the rotational force generated by the driving member 308 is well transmitted to the force transmission member 304, the insertion portion 808 is a projection ( 800).

The fastening member 802 is coupled to a thread 810 formed at the end of the MET body 306. When the driving member 308 is coupled to the incomplete cylindrical groove 702, even if an external force (vibration, impact, etc.) occurs, the driving member 308 is separated out by the fixing member 802 coupled to the thread 810. It doesn't work. That is, the fixing member 802 fixes the driving member 308, and thus a structure corresponding to the thread 810 is formed therein.

The fixing members 804 and 806 are coupled onto the threaded line 812 formed on the outer circumferential surface of the force transmission member 304 to prevent the display member 314 or the like from being separated by the external force.

As described above, the MET element 300 of the present invention rotates the force transmission member 304 through the method of rotating the drive member 308. That is, unlike the conventional MET elements which linearly moved according to the operation of the driving member, in the MET element 300 of the present invention, the force transmission member 304 rotates according to the operation of the driving member 308. Of course, as described above, the phase shifter operates in response to the rotational movement of the force transmission member 304.

In addition, the outer peripheral surface of the drive member 308 is formed with an insertion portion 312 to which the remote control device 330 can be coupled. Thus, the MET element 300 of the present invention can couple the remote control device 330 to the drive member 308 without removing certain members. Thus, the MET element 300 of the present invention can more easily engage and disengage the remote control device 330 than the conventional MET elements.

According to one embodiment of the invention, when the remote control device 330 is inserted into the insertion portion 312 with the drive member 308 fixed to the incomplete cylindrical groove 702, the drive member 308 is incomplete It may be detached from the cylindrical groove 702 and automatically coupled to the cylindrical groove 700.

9 is a perspective view showing the internal structure of the MET device according to an embodiment of the present invention.

As shown in FIG. 9, at least one protrusion 308 is formed on the driving member 308 to prevent a user's hand from slipping, and the driving member 308 and the force transmission member 304 are coupled to an inner surface thereof. Protruding portion 800 is formed. Here, although the shape of the protrusion 800 may be variously modified, it is preferable to have a polygonal structure in order to transfer the rotational force generated by the driving member 308 to the force transmission member 304 well.

In addition, at least one hook member 900 is formed at the end of the driving member 308 as shown in FIG. 9. This hook member 900 is coupled to the cylindrical groove 700 or the incomplete cylindrical groove 702 of the MET body 306.

According to one embodiment of the invention, the number of incomplete cylindrical grooves 702 is greater than the number of hook members 900. For example, the number of incomplete cylindrical grooves 702 is twice the number of hook members 900. Thus forming the incomplete cylindrical grooves 702 more than the number of hook members 900 by coupling the hook members 900 to the incomplete cylindrical groove 702 in any position to drive the drive member 308 to the MET body ( To 306) stably.

In short, the MET element 300 of the present invention uses the protrusion 800 to couple the driving member 308 and the force transmission member 304, and is driven using the hook member 900 and the grooves 700 and 702. The member 308 is fixed to the MET body 306. As a result, the MET element 300 can easily transfer the rotational force generated by the drive member 308 to the force transmission member 304 as well as provide a simple method for the drive member 900 to the MET body 306. Can be fixed through Thus, the user can easily manipulate the MET element 300.

In the above, although the force transmission member 304 is rotated by the rotation of the drive member 308, the force transmission member 304 may have a structure that linearly moves in accordance with the rotation of the drive member 308. Of course, in this case the underlying structure of the phase shifter will also be modified.

Hereinafter, the functions of the MET protrusion 316 and the RET protrusion 328 will be described through practical examples.

FIG. 10 is a cross-sectional view illustrating tilt angle adjusting devices, and FIG. 11 is a diagram illustrating an impact test on the tilt angle adjusting devices of FIG. 10.

The second inclination angle adjusting device of the present invention in which the first inclination angle adjusting device 1100-1 in which the protrusions shown in FIG. 10A are not formed and the protrusions 316 and 328 shown in FIG. 10B are formed ( 1100-2). In detail, as shown in FIG. 11, one side (MET element) of the tilt angle adjusting device 1100 is connected to the antenna 1102, and the load 1104 is connected to the other side of the tilt angle adjusting device 1100. Thereafter, the load 1104 was thrown in the front direction, the right direction, the left direction, and the rear direction of the antenna 1102 so that a force was applied to the inclination angle adjusting device 1100.

First, an experimental result of the first inclination angle adjusting device 1100-1 in which protrusions are not formed will be described with reference to Table 1 below. Here, the diameter d of the MET body 306 was set to 30.4 mm, and the diameter D of the RET body 320 was set to 30.7 mm.

Experimental Results (Applied Torque: 10Nm) 1 ^st 2 ^nd 3 ^rd 4 ^th 5 ^th front-side pass fail fail fail fail right-side fail fail fail fail fail left-side fail fail fail fail fail back-side fail fail fail fail fail

When a force is applied to the first inclination angle adjusting device 1100-1 where the protrusions are not formed, the RET element is shown in FIG. 3C because the distance between the MET element 1000 and the RET element 1002 is wide. 1002 is tilted. In this case, since the MET element 1000 is fixed to the antenna 1102, the remote control device 1004 fixed to the RET element 1002 is maintained while maintaining the original state even when the force is applied. Tilt together as it tilts. Therefore, the rotation axis 1012 of the remote control device 1004 is inclined as shown in FIG. 10 (C), so that the rotation axis 1012 does not rotate by the number of times input by the user (or within an error range). You may not be able to. That is, the rotational force as desired by the user may not be provided to the MET element 1000 through the remote control apparatus 1004, so that the desired tilt angle adjustment may not be obtained. According to an embodiment of the present invention, the rotation speed of the rotation shaft 1012 may be sensed by an encoder connected to the rear end of the body 1010 of the remote control apparatus 1004. In this case, the user determines that the detected rotational speed is within a range of an error of the desired rotational speed, and determines that the detected rotational speed is a failure. For example, when the desired rotational speed is 100 times and the error range is set to 5, it is determined as a fail when the rotational axis 1012 of the remote control device 1004 is rotated only 90 times by the force.

As shown in Table 1 above, in the case of the first inclination angle adjusting device 1100-1, the rotational speed of the remote control device 1004 exceeds the error range by the force except for one time and is determined as the majority fail. It became.

Next, an experimental result of the second inclination angle adjusting device 1100-2 having the protrusions 316 and 328 will be described. Here, the diameter d of the MET protrusion 316 was set to 30.4 mm, and the diameter D of the RET protrusion 328 was set to 30.7 mm. That is, the interval between the protrusions 316 and 328 was set to 0.15 mm.

When the force is applied to the second tilt angle adjusting device 1100-2 in which the protrusions 316 and 328 are formed, the protrusions 316 and 328 cause the RET element 302 not to be tilted and remain almost original. do. As a result, the remote control device 330 fixed to the RET element 302 also maintains its original state, that is, the rotary shaft 1022 of the remote control device 330 is inserted into the insertion portion 312 of the fixing member 308. Maintain stable insertion. Thus, the rotation axis 1022 of the remote control device 330 can be rotated as many times as desired. In fact, as shown in Table 2, all were determined to pass even though a force was applied to the second tilt angle adjusting device 1100-2.

In the above, the difference between the diameter d of the MET protrusion 316 and the diameter D of the RET protrusion 328 is set to 0.3 mm, but the difference between the diameters d and D is about 0.2 mm to about 0.3 mm. When the experiment result was judged to be the majority pass.

In short, the tilt angle adjusting device of the present invention is generated by the remote control device 330 using the MET protrusion 316 formed on the outer circumferential surface of the MET element 300 and the RET protrusion 328 formed on the inner circumferential surface of the RET element 302. Rotated force may be transmitted to the fixing member 308 of the MET element 300.

In the above, protrusions 316 and 318 are formed in both the MET element 300 and the RET element 302, but the protrusion may be formed in only one of the MET element 300 and the RET element 302. For example, a protrusion may be formed on an outer circumferential surface of the MET element 300, and the protrusion may be arranged in close contact with an inner circumferential surface of the RET element 302.
