Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle testing devices, and in particular to a unmanned aerial vehicle interference capability testing device and a use method thereof. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device or is operated completely or intermittently autonomously by an onboard computer. Usually, drones need to undergo various functional tests before leaving the factory, and the wind resistance test of drones is one of them.

[0003] However, most of the current wind resistance tests are carried out by setting up large wind turbines and test equipment in the test field. The test equipment is large in size and needs to be tested in a designated place. For some ordinary drone enthusiasts, it is very inconvenient to test their own drones without professional large-scale test equipment. At the same time, the existing test equipment is large in size and cannot adapt to the use of various environments. It is restricted by factors such as the site and weather, and cannot be tested and used at any time. In addition, the wind turbines used are fixed in designated locations, and the test wind direction is limited. It is impossible to flexibly adjust the wind direction to fully test the performance of the drone. Summary of the invention

[0012] A method for using a drone interference capability testing device comprises the following steps:

[0013] Place the drone to be tested in the center of the support plate, start the drone and make it hover at the height when the turbine blower is horizontal, start the drive motor, and the drive motor drives the spur gear fixed to it to rotate. Since the spur gear is meshed with the gear ring fixed to the floor, the drive motor will be subjected to a reaction force, thereby driving the mounting base fixed to it to slide along the annular slide rail;

[0014] When the mounting seat starts to move, the limit block connected to the mounting seat will move away from the upper bracket, so that the upper bracket moves down along the fixing rod under the tension of the second spring. When the upper bracket moves down, the upper bracket and the lower bracket will expand outward, thereby driving the flexible protective layer to unfold under the drone, thereby protecting the drone from falling.

[0015] During the circling process of the mounting seat, since the guide rod 1 is slidably connected in the wavy guide groove, the ball nut seat fixedly connected to the guide rod 1 will reciprocate up and down, driving the screw rod threadedly connected thereto to rotate reciprocatingly, and the screw rod drives the rotating rod to rotate reciprocatingly through the engaged connector 1 and connector 2, and the rotating rod drives the long rod fixedly connected thereto to rotate reciprocatingly, and since the guide rod 2 is slidably connected in the spiral groove, the cylinder 4 is reciprocated and lifted up and down under the drive of the long rod, and the turbine blower connected to the cylinder 4 will also reciprocate and lift up and down, but under the guidance of the arc-shaped slide groove 1 and the arc-shaped slide groove 2, the turbine blower will deflect during the movement, thereby changing the position causing interference on the drone and enhancing the test effect;

[0016] When testing at a specific angle is required, the adjustment rod can be moved from the long slot to the short slot to disengage the connector 1 and the connector 2, so that the position of the turbine blower will not change during the movement.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, by setting up a surrounding mechanism, the turbo blower can be driven to move around the UAV, thereby being able to interfere with the blowing of the UAV at various angles, and the anti-interference performance of the UAV can be effectively measured. In the process of surrounding operation, the turbo blower can also be made to swing back and forth to further enhance the interference effect on the UAV, thereby achieving more extreme testing of the UAV.

[0019] In the present invention, a switching mechanism is set up and the separation of connector one and connector two is controlled by moving the adjusting rod, so that the turbine hair dryer will not swing during the movement, and the effect of surrounding blowing at a specific angle can be achieved, thereby increasing the types of interference tests on drones and having a wider range of applications.

[0020] In the present invention, by setting up a protection mechanism, when the surrounding mechanism starts to operate, the flexible protection layer can be quickly unfolded under the drone, and the drone can be caught when it falls due to interference, thereby preventing the drone from falling and being damaged, causing property loss.

[0038] In this embodiment, there is a large transmission ratio between the screw rod 403 and the ball nut seat 404, so that when the ball nut seat 404 moves a small distance, the screw rod 403 will also rotate more circles. At the same time, the pitch of the spiral groove 706 is set to be large, so that it can drive the cylinder four 702 to move a larger distance when the ball nut seat 404 rotates the same number of circles as the screw rod 403.

[0040] In this embodiment, the protection mechanism 11 includes a fixing rod 1101, a lower bracket 1102 and an upper bracket 1103, the corner angles of the lower bracket 1102 and the upper bracket 1103 are equal to the angles of the inner angles of the regular hexagon, the fixing rod 1101 is fixedly connected to the supporting plate 10, six lower brackets 1102 are evenly distributed, one of the lower brackets 1102 is fixedly connected to the lower end of the fixing rod 1101, and the six upper brackets 1103 correspond to the positions of the lower brackets 1102 one by one, one of the upper brackets 1103 is slidably connected to the upper end of the fixing rod 1101, and the upper bracket 1103 A spring two 1104 is connected between the upper bracket 1103 and the lower part, a connecting rod 1105 is connected between the adjacent ends of the upper bracket 1103 and the lower brackets 1102 on both sides, and the two crossed connecting rods 1105 are hinged at the center position.

[0041] In this embodiment, the position of the fixing rod 1101 deviates from the center of the support plate 10, thereby avoiding obstruction to the placement of the drone. Since the flexible protective layer 1106 is at a certain distance from the support plate 10 after being unfolded, it has a better protection effect compared to the existing method of placing a protective pad on the support plate 10.

[0042] In this embodiment, when the test is completed, the upper bracket 1103 is manually pushed up and engaged with the limit block 1108 to retract the protection mechanism 11, so that the drone can land on the supporting plate 10.

[0043] A method for using a drone interference capability testing device comprises the following steps:

[0044] The drone to be tested is placed in the center of the support plate 10, the drone is started and hovered at the height when the turbine blower 9 is horizontal, and the drive motor 302 is started. The drive motor 302 drives the spur gear 303 fixedly connected thereto to rotate. Since the spur gear 303 is meshed with the gear ring 304 fixedly connected to the floor, the drive motor 302 is subjected to a reaction force, thereby driving the mounting seat 301 fixedly connected thereto to slide along the annular slide rail 2;

[0045] When the mounting seat 301 starts to move, the limit block 1108 connected to the mounting seat 301 will move away from the upper bracket 1103, so that the upper bracket 1103 moves down along the fixing rod 1101 under the pulling force of the second spring 1104. When the upper bracket 1103 moves down, the upper bracket 1103 and the lower bracket 1102 will expand outward, thereby driving the flexible protective layer 1106 to unfold under the drone, thereby protecting the drone from falling.

[0046] During the orbiting process of the mounting seat 301, since the guide rod 1 407 is slidably connected in the wavy guide groove 501, the ball nut seat 404 fixedly connected to the guide rod 1 407 will move back and forth up and down, driving the screw rod 403 threadedly connected thereto to rotate back and forth, and the screw rod 403 drives the rotating rod 603 to rotate back and forth through the engaged connector 1 604 and connector 2 606, and the rotating rod 603 drives the long rod 705 fixed thereon to rotate back and forth, and since the guide rod 2 704 is slidably connected in the spiral groove 706, the cylinder 4 702 is reciprocated and lifted up and down under the drive of the long rod 705, and the turbine blower 9 connected to the cylinder 4 702 will also be reciprocated and lifted up, but under the guidance of the arc-shaped slide groove 1 809 and the arc-shaped slide groove 2 810, the turbine blower 9 will deflect during the movement, thereby changing the position causing interference on the drone, thereby enhancing the test effect;

[0047] When testing at a specific angle is required, the adjustment rod 608 can be moved from the long slot 609 to the short slot 610, so that the connector 1 604 and the connector 2 606 are disengaged, so that the position of the turbo blower 9 will not change during the movement.

A spring second (1104) is connected, a connecting rod (1105) is connected between the adjacent ends of the upper bracket (1103) and the lower brackets (1102) on both sides, and the two crossed connecting rods (1105) are hinged at the center position. A flexible protective layer (1106) is also fixedly connected to the upper bracket (1103), a guide rod (1107) is fixedly connected to the connecting bracket second (806), and a limit block (1108) is slidably connected to the guide rod (1107), a spring three (1109) is connected between the limit block (1108) and the connecting bracket second (806), and the upper bracket (1103) on the fixed rod (1101) abuts against the upper surface of the limit block (1108).

8. A method for using a UAV interference capability testing device according to any one of claims 1 to 7, characterized in that: The steps include: The drone to be tested is placed in the center of the support plate (10), the drone is started and hovered at the height when the turbo blower (9) is horizontal, and the drive motor (302) is started. The drive motor (302) drives the spur gear (303) fixedly connected thereto to rotate. Since the spur gear (303) is meshed with the gear ring (304) fixedly connected to the floor, the drive motor (302) is subjected to a reaction force, thereby driving the mounting seat (301) fixedly connected thereto to slide along the annular slide rail (2); When the mounting seat (301) starts to move, the limit block (1108) connected to the mounting seat (301) will move away from the upper bracket (1103), so that the upper bracket (1103) moves downward along the fixing rod (1101) under the pulling force of the second spring (1104). When the upper bracket (1103) moves downward, the upper bracket (1103) and the lower bracket (1102) will expand outward, thereby driving the flexible protective layer (1106) to unfold under the drone, thereby protecting the drone from falling. During the process of the mounting seat (301) being encircled, since the guide rod 1 (407) is slidably connected in the wave-shaped guide groove (501), the ball nut seat (404) fixedly connected to the guide rod 1 (407) will reciprocate up and down, driving the screw rod (403) threadedly connected thereto to reciprocate, and the screw rod (403) drives the rotating rod (603) to reciprocate through the engaged connector 1 (604) and connector 2 (606), and the rotating rod (603) drives the long rod ( 705) reciprocates, and since the guide rod 2 (704) is slidably connected in the spiral groove (706), the cylinder 4 (702) is reciprocated and lifted under the drive of the long rod (705), and the turbine blower (9) connected to the cylinder 4 (702) also reciprocates and lifts, but under the guidance of the arc-shaped slide groove 1 (809) and the arc-shaped slide groove 2 (810), the turbine blower (9) will deflect during the movement, thereby changing the position causing interference on the drone and enhancing the test effect; When testing at a specific angle is required, the adjustment rod (608) can be moved from the long slot (609) to the short slot (610), thereby disengaging connector 1 (604) and connector 2 (606), so that the position of the turbo blower (9) will not change during the movement.
