1 to 7 , the lifting compensation mechanism 500 according to the present embodiment is a member for compensating for the lifting obstruction force that prevents the lifting of the lifting body 10 when the lifting body 10 is lifted. That is, the elevation compensation mechanism 500 may provide a compensation force corresponding to the elevation obstruction force to the elevation mechanism 300 in a direction opposite to the elevation obstruction force. To this end, the elevation compensation mechanism 500 may be connected to the test device case 200 and the elevation mechanism 300 .

The elevating obstruction force is a force that prevents the normal elevation of the elevating body 10 due to the elevating motion test device 100 connected to the elevating body 10 when the elevating body 10 is lifted. The weight of the mechanism 400 and the lifting mechanism 300 or the friction force generated during the lifting operation of the lifting mechanism 300 may be included. The frictional force of the elevating mechanism 300 may always be applied in a direction opposite to the elevating direction of the elevating body 10 . The weight of the elevating measuring device 400 and the elevating mechanism 300 may act in a direction opposite to the rising direction of the elevating body 10 when the elevating body 10 is raised, and elevating and lowering when the elevating body 10 is lowered. It may act in the same direction as the downward direction of the moving body 10 .

However, the weight of the elevating mechanism 400 and the elevating mechanism 300 is relatively larger than the friction force of the elevating mechanism 300, and the frictional force of the elevating mechanism 300 is a friction-reducing structure such as a bearing and lubricating oil to the friction part. It is possible to apply or reduce in a way that improves the lifting mechanism of the lifting mechanism 300 . Therefore, hereinafter, for convenience of explanation of the present invention, it will be described that the lifting impeding force is equal to the weight of the lifting measuring mechanism 400 and the lifting mechanism 300 . That is, in this embodiment, in order to prevent the abnormal lifting operation of the lifting body 10 due to the lifting impeding force during the lifting performance test of the lifting body 10, the lifting compensation mechanism 500 includes the lifting measuring mechanism 400 and the lifting mechanism.

The compensator rod 510 as described above may perform a function of guiding the lifting operation of the compensator 520 in the vertical direction, and may perform a function of setting the compensator 520 in the correct position.

As shown in FIGS. 1 to 4 and 7 , the compensator 520 is a member for providing a compensating weight corresponding to the lifting obstruction force. The compensator rod 510 and the compensator 520 may be disposed in a space between the elevating mechanism 300 and the test apparatus case 200 so as not to interfere with the elevating mechanism 300 when the elevating mechanism 300 is lifted. .

For example, the compensator 520 according to the present embodiment is arranged to be liftable on the compensator rod 510 and is formed by a first compensation weight and a main compensator 522 and a compensation provided in the main compensator 522 . The sieve mounting unit 524 and at least one of the compensator mounting units 524 may include a sub compensator 526 selectively mounted thereon and formed with a second compensation weight.

The main compensator 522 may be formed in a panel shape in which a central portion is hollow. The main compensator 522 may be formed with a first compensating weight that is slightly smaller than the lifting impeding force. A sliding hole through which the plurality of compensator rods 510 are slidably inserted may be formed at the edge of the main compensator 522 , and the elevating mechanism 300 passes through the hollow portion of the main compensator 522 . A compensator hole 522a to be disposed may be formed.

An appropriate number of sub compensators 526 may be selectively mounted to the main compensator 522 by the compensator mounting unit 524 .

That is, the sub compensator 526 is a means for filling the difference between the first compensation weight of the main compensator 526 and the lifting impeding force, and the compensator 520 is mounted in an appropriate number in the compensator mounting unit 524 . It is possible to make the compensating weight and lifting obstacle of the same size the same. Accordingly, the first compensation weight of the main compensator 522 and the second compensation weight of the at least one sub compensator 526 are

The total weight may be formed to have the same size as the lifting impeding force.

The compensator mounting unit 524 is a structure for mounting at least one sub compensator 526 to the main compensator 522 , if it has a structure capable of mounting the sub compensator 526 to the main compensator 522 . All are applicable. For example, the compensator mounting unit 524 may be formed by a screw fastening method, a clamp fixing method, a wire binding method, or the like. Hereinafter, in this embodiment, it will be described that the compensator mounting part 524 is formed in a screw fastening method and disposed on the upper surface front part and the upper surface rear part of the main compensator 522, respectively. That is, the same number of sub compensators 526 may be mounted on the front and rear surfaces of the main compensator 522 in a stacked structure.

Meanwhile, the main compensator 522 or the sub compensator 526 may be formed to have a quantified or standardized weight according to a shape or shape. By forming in this way, it is possible to easily adjust the compensation weight as required by selecting the main compensator 522 or the sub compensator 526 according to the shape or shape.

1 to 4 and 7 , the compensating force providing unit 530 converts the compensating weight of the compensating body 520 into compensating force for compensating for the lifting impeding force and provides it to the lifting mechanism 300 . is the absence of

For example, the compensating force providing device 530 according to the present embodiment provides the compensating weight of the compensating body 520 as the compensating force of the lifting mechanism 300 to the compensating body 520 and the lifting mechanism 300 . A compensation wire 532 having both ends connected, and a compensation wire 532 connected to the compensation wire 532 are disposed in the test device case 200 and change the direction of travel of the compensation wire 532 to change the direction of action of the compensation weight to the compensation direction A roller 534 may be included.

One end of the compensation wire 532 may be connected to the main compensator 522 , and the other end of the compensation wire 532 may be connected to the rod bracket 320 of the lifting mechanism 300 . The compensation roller 534 may be mounted on the upper surface of the test apparatus case 200 . A plurality of compensation wires 532 and compensation rollers 534 may be disposed along the circumference of the elevation mechanism 300 or the elevation compensation mechanism 500 .

On the other hand, the lifting motion test apparatus 100 according to an embodiment of the present invention may further include a thrust measuring mechanism (not shown) for measuring the lifting thrust of the lifting body (10). The thrust measuring mechanism as described above may be disposed between the test device case 200 and the elevation mechanism 300 or between the test device case 200 and the elevation compensation mechanism 500 .

For example, the thrust measuring mechanism may include an elastic body that is elastically deformed according to the lifting operation of the lifting body 10 , and a load cell disposed on the elastic body to measure the lifting thrust of the lifting body 10 .

Here, one end of the elastic body may be connected to the installation bracket 312 of the elevating mechanism 300 , and the other end of the elastic body may be connected to the upper outer surface of the test apparatus case 200 .

The compensator 520 according to the present invention is a member for providing a compensation weight corresponding to the lifting force. A steel material may be used to increase the weight of the compensator 520 , but in this case, it is preferable to provide a dielectric case surrounding the compensator 520 to absorb electromagnetic waves.

The operation and effect of the lifting movement test apparatus 100 of the lifting movement body 10 according to an embodiment of the present invention configured as described above will be described.

First, the lifting body 10 is mounted on the mounting frame 420 of the lifting measuring device 400 , and the test device cable 340 and the external cable 350 are connected. Hereinafter, for convenience of explanation, the elevating body 10 is limited to an unmanned aerial vehicle such as a drone that is radio-controlled.

The lifting motion test device 100 is operated to stand by in the initial preparation state for the lifting performance test of the lifting body 10 .

In the initial preparation state of the elevating motion test apparatus 100 as described above, the elevating mechanism 300 is lowered to the lowest side, and the elevating measuring mechanism 400 is seated on the seating support member 230 of the test apparatus case 200 . is in a state of being

Then, the lifting and lowering body 10 is controlled by radio to elevate. That is, in order to test the lifting performance of the elevating body 10 , the elevating body 10 is elevated or the elevating direction and the elevating speed of the elevating body 10 are variously changed.

At this time, the mounting frame 420 of the elevating measuring mechanism 400 rotates or turns around the universal joint 410 according to the elevating direction of the elevating body 10 , and the elevating measuring unit of the elevating measuring device 400 is the elevating body 10 . (10) Detects the lifting performance in real time.

After the elevating measuring unit of the elevating measuring mechanism 400 as described above detects the elevating performance of the elevating body 10, the data on the elevating performance of the elevating body 10 is digitized, and the control unit of the elevating motion test apparatus 100 is The elevating performance data of the elevating body 10 is received and the elevating performance of the elevating body 10 is analyzed.

Then, the lifting performance of the lifting body 10 is inferred based on the test result of analyzing the lifting performance of the lifting body 10 .

Therefore, by using the lifting test result of the lifting body 10, design errors of the lifting body 10, performance defects of the lifting body 10, or component problems of the lifting body 10 can be confirmed and improved. Thus, it is possible to optimize the lifting and lowering body 10 .

On the other hand, since the lifting motion test apparatus 100 has a structure connected to the elevating body 10 , some configurations of the elevating motion test apparatus 100 interfere with the elevating movement of the elevating body 10 in the elevating process of the elevating body 10 . However, the lifting compensation mechanism 500 of the lifting motion test apparatus 100 prevents abnormal elevation of the lifting body 10 in advance. That is, since the lifting and lowering measuring mechanism 400 and the lifting mechanism 300 of the lifting motion test apparatus 100 have a structure that is raised and lowered like the lifting body 10 , the weight of the lifting measuring mechanism 400 and the lifting mechanism 300 is It acts on the elevating body 10 in a direction that prevents the elevation of the elevating body 10 .

For this reason, the lifting compensation mechanism 500 compensates for the lifting obstruction force that prevents the lifting and lowering of the lifting body 10 to normalize the lifting operation of the lifting body 10 .

The operation of the elevation compensation mechanism 500 will be described in more detail as follows.

When the elevating body 10 rises upward, the elevating measuring mechanism 400 and the elevating mechanism 300 rise together with the elevating body 10 . At this time, the elevating rod 310 of the elevating mechanism 300 moves to protrude upward of the test apparatus case 200 along the elevating measuring mechanism 400 as the elevating body 10 rises.

When the lifting rod 310 is raised as described above, the connector member 330 rises together with the rod bracket 320 inside the test device case 200 , and the test device cable 340 is also connected with the connector member 330 . It moves upward along the elevating rod 310 while being connected to the elevating measuring unit. At this time, the weight of the lifting measuring mechanism 400 and the lifting mechanism 300 is a lifting impeding force acting in a direction opposite to the ascending direction of the lifting body 10 , and distorts the lifting performance of the lifting body 10 .

However, when the rod bracket 320 of the lifting mechanism 300 is raised, the compensator 520 of the lifting compensation mechanism 500 is moved by the compensating wire 532 of the compensating force provider 530 to the rod bracket 320 . It compensates for the obstacle to ascending and descending while descending in conjunction with the . Here, the moving distances of the compensator 520 and the rod bracket 320 are the same, but the moving directions are opposite to each other.

Therefore, when the elevating body 10 is raised, the lifting impeding force applied to the elevating body 10 is compensated by the compensator 520 having the same compensation weight as the weight of the elevating mechanism 400 and the elevating mechanism 300 . , When the elevating body 10 is raised, the lifting compensation mechanism 500 cancels all of the lifting impeding forces acting on the elevating body 10 so that the lifting operation of the elevating body 10 is normally performed.

When the elevating body 10 descends downward, the elevating measuring mechanism 400 and the elevating mechanism 300 descend together with the elevating body 10 . At this time, the elevating rod 310 of the elevating mechanism 300 moves to be inserted into the test apparatus case 200 along the elevating measuring mechanism 400 according to the lowering of the elevating body 10 .

When the lifting rod 310 is lowered as described above, the connector member 330 descends together with the rod bracket 320 inside the test apparatus case 200 , and the test apparatus cable 340 is also connected with the connector member 330 . It moves downward along the elevating rod 310 in a state connected to the elevating measuring unit. At this time, the weight of the lifting measuring device 400 and the lifting mechanism 300 is lower than the lifting body 10 .

As a lifting and lowering impeding force acting in the same direction as the moving direction, the lifting performance of the lifting body 10 is distorted.

However, when the rod bracket 320 of the elevating mechanism 300 is lowered, the compensator 520 of the elevating compensating mechanism 500 is moved by the compensating wire 532 of the compensating force provider 530 to the rod bracket 320 . It compensates for the obstacle to ascending and descending while ascending in conjunction with the . Here, the moving distances of the compensator 520 and the rod bracket 320 are the same, but the moving directions are opposite to each other.

Therefore, when the elevating body 10 is lowered, the lifting disturbance force applied to the elevating body 10 is compensated by the compensator 520 having the same compensation weight as the weight of the elevating measuring mechanism 400 and the elevating mechanism 300 . , When the elevating body 10 is lowered, the lifting compensation mechanism 500 cancels all the lifting impeding forces acting on the elevating body 10 , so that the lowering operation of the elevating body 10 is also performed normally.

In particular, an insulating layer is formed around the outer periphery of the test apparatus case 200 , the lifting mechanism 300 , the lifting measuring mechanism 400 , and the lifting compensation mechanism 500 according to the present invention. The insulating layer may be formed in multiple layers. The multi-layered insulating layers may be concavo-convex bonding to each other.

An embossed protrusion may be formed on the outer surface of the outermost insulating layer.

Here, the component parts are arranged inside the test apparatus case 200 , the lifting mechanism 300 , the lifting measuring mechanism 400 , and the lifting compensation mechanism 500 . Each of the components may be coated on the outer surface using an additional insulating material. Accordingly, an insulating coating layer is formed on the outer surface of the component parts. The insulating coating layer may be coated by spraying an insulating material.

In addition, the rotation support 410 may also be formed with a multi-layered insulating layer on the outer surface as described above. Of course, the rotation support 410 itself may be formed of an insulating component.

In addition, the rotation support 410 includes a plurality of support legs 411 extending upward, and a seating plate 412 installed on the plurality of support legs 411 . The lifting body 10 is seated on the mounting plate 412 .

A vibration sensor 413 is installed on the seating plate 412 . The vibration sensor 413 measures the vibration generated in the seating plate 412 and transmits it to the controller.

And a vibration generator 414 is installed at the lower end of the seating plate 412 . The vibration generator 414 generates a predetermined vibration under the control of the controller and transmits it to the seating plate 412 .

The controller receives the vibration measured from the vibration sensor 413 and calculates an offset vibration value capable of canceling the measured vibration.

The controller controls the driving of the vibration generator 414 to generate the calculated offset vibration value. The vibration generator 414 transmits the vibration corresponding to the offset vibration value to the seating plate 412 .

Accordingly, the vibration generated by the vibration generated during the operation of the lifting body 10 seated on the seating plate 412 is offset to induce a stable seating regardless of the operation of the lifting body 10 on the seating plate 412 . , through this, a stable flight test can be made.

According to the above configuration and action, the present invention has the effect of more accurately and precisely performing the lifting test of the lifting and lowering body.

In addition, the present invention has the effect of securing the stability and reliability of the lifting test by removing the resistive force acting as a structural problem of the lifting movement test device when the lifting movement body is raised.

In addition, the present invention has the effect that it can be suitably used for performance tests on elevating objects such as drones or multicopters.

In addition, the present invention has the effect that the electromagnetic wave certification test is possible.

In addition, the present invention has the effect that it is possible to perform a performance test on a lifting body moving up and down in postures of various angles.

In addition, the present invention has the effect of achieving a stable test standby state by removing the vibration from the seating plate on which the elevating moving body is seated in which the vibration is generated.

As described above, specific embodiments of the present invention have been described, but it is apparent that various implementation modifications are possible within the limits that do not depart from the scope of the present invention.
