[0017] Compared with the prior art, the present invention provides a landing support device for an autogyro, which has the following

[0018] Beneficial effects:

[0019] 1. For this landing support device of the autogyro, when the autogyro needs landing support, turn on the first motor. When the first motor is working, it drives the first pulley to rotate. At this time, the first pulley drives the second pulley to rotate through the first belt, and then makes the rotating rod in the middle of the second pulley rotate. At the same time, when the rotating rod rotates, it drives the first lead screw to rotate, and then makes the first ball screw nut pair lift on the first lead screw. At the same time, the connecting plate is lifted, and then the buffer box can be moved out of the lifting groove, making the buffer wheel contact the ground.

[0020] 2. For this landing support device of the autogyro, when the buffer wheel contacts the ground, the first spring in the buffer box is compressed, making the damping wheel on the first spring slide on the rubber plate on the inner wall of the buffer box. By setting the rubber plate, the force during falling can be buffered, the resistance can be increased, and the vibration when contacting the ground during falling can be reduced, avoiding damage to the autogyro due to vibration.

[0021] 3. For the autogyro landing support device, turn on Motor 2. When Motor 2 is working, it drives Pulley 3 to rotate. Pulley 3 drives Belt 4 to rotate through Belt 2, thereby causing Ball Nut Pair 2 to move on Lead Screw 2, making the moving baffle move along with Ball Nut Pair 2. Guide Ring 2 on the moving baffle moves on the guide rod, making the movement of the moving baffle more stable. At the same time, the moving baffle moves away from the lifting slot, and the lifting operation can be controlled.

[0022] 4. For the autogyro landing support device, by setting Motor 1 and Motor 2 as reversible motors, the buffer box can be retracted into the drive box as needed. At the same time, the lifting slot at the bottom of the closed box can be controlled to be closed or opened, preventing foreign objects from entering the bottom of the closed box during use.

The first motor 401 is fixedly connected to the middle of the inner top of the driving box 2. The first motor 401 has an output shaft. The first pulley 402 is fixedly connected to the output shaft of the first motor 401. The left end of the first belt 403 is drivingly connected to the first pulley 402. The second pulley 404 is drivingly connected to the right end of the first belt 403. The first rotating rod 405 is fixedly connected to the center of the second pulley 404.

The first ball screw pair 407 is threadedly connected to the front of the first lead screw 406 near the top. The connecting plate 408 is fixedly connected to the left side of the first ball screw pair 407. When the autogyro 1 needs to land and support, the first motor 401 is turned on. When the first motor 401 works, it drives the first pulley 402 to rotate. At this time, the first pulley 402 drives the second pulley 404 to rotate through the first belt 403, so that the first rotating rod 405 in the middle of the second pulley 404 rotates. At the same time, when the first rotating rod 405 rotates, it drives the first lead screw 406 to rotate, so that the first ball screw pair 407 moves up and down on the first lead screw 406, and at the same time, the connecting plate 408 moves up and down, so that the buffer box 509 can be moved out of the lifting groove, and the buffer wheel 508 contacts the ground.

[0037] The buffer mechanism 5 includes a connecting frame 501, a first spring 502, a support frame 503, a buffer groove 504, a second spring 505, a moving block 506, a connecting rod 507, a buffer wheel 508 and a buffer box 509. The connecting frame 501 is fixedly connected to the right side of the bottom of the connecting plate 408. The first spring 502 is fixedly connected to the bottom of the connecting frame 501. The right side of the inner bottom of the buffer box 509 is fixedly connected to the bottom end of the first spring 502.

The second spring 505 is fixedly connected to the right side inside the buffer groove 504. The moving block 506 is fixedly connected to the left end of the second spring 505. The connecting rod 507 is rotatably connected to the top of the moving block 506. The buffer wheel 508 is fixedly connected to the bottom of the buffer box 509. When the buffer wheel 508 contacts the ground, the first spring 502 in the buffer box 509 is compressed, so that the damping wheel on the first spring 502 slides on the rubber plate on the inner wall of the buffer box 509. By setting the rubber plate, the force during falling can be buffered, the resistance can be increased, the vibration when contacting the ground during falling can be reduced, and the autogyro 1 can be prevented from being damaged due to vibration.

[0038] The closing mechanism 6 includes a second motor 601, a third pulley 602, a second belt 603, a fourth belt 604, a second rotating rod 605, a second lead screw 606, a second ball screw pair 607, a moving baffle 608 and a guide rod 609. The second motor 601 is fixedly connected to the middle of the rear end of the inner bottom of the drive box 2. The second motor 601 has an output shaft. The third pulley 602 is fixedly connected to the output shaft of the second motor 601. The top end of the second belt 603 is drivingly connected to the third pulley 602. The fourth belt 604 is drivingly connected to the bottom end of the second belt 603. The second rotating rod 605 is fixedly connected to the center of the fourth belt 604. The second lead screw 606 is fixedly connected to the right end of the second rotating rod 605. The second ball screw pair 607 is threadedly connected to the front of the second lead screw 606 near the left end. The moving baffle 608 is fixedly connected to the front of the second ball screw pair 607. The guide rod 609 is fixedly connected to the front ends of the left and right sides inside the drive box 2. When the second motor 601 is turned on, the second motor 601 drives the third pulley 602 to rotate during operation. The third pulley 602 drives the fourth belt 604 to rotate through the second belt 603, thereby causing the second ball screw pair 607 to move on the second lead screw 606, so that the moving baffle 608 moves along with the second ball screw pair 607. The second guide ring on the moving baffle 608 moves on the guide rod 609, making the movement of the moving baffle 608 more stable. At the same time, the moving baffle 608 moves away from the lifting groove, and the lifting operation can be controlled.

[0039] One end of the connecting rod 507 away from the moving block 506 is hinge-connected with a fixed block. The top of the fixed block is fixedly connected to the right side of the bottom of the connecting plate 408. The bottom of the moving block 506 is fixedly connected with a first guide ring. The middle part of the supporting frame 503 is slidably connected to the center of the first guide ring, which can make the first guide ring slide on the supporting frame 503.

[0040] Rubber wheels are arranged on the front and back of the moving block 506. The shapes of the top and bottom of the inner part of the buffer groove 504 are uneven. The rubber wheels are slidably connected to the buffer groove 504. A damping wheel is rotatably connected to the middle part on the right side of the connecting frame 501. A rubber plate is fixedly connected to the right inner wall of the buffer box 509. The damping wheel is slidably connected to the rubber plate, which can make the rubber wheels slide on the inner wall of the buffer groove 504.

[0041] A storage battery is fixedly connected to the rear end on the right side of the inner bottom of the drive box 2. The storage battery is electrically connected to the first motor 401 and the first pulley 402. Both the first motor 401 and the first pulley 402 are motors that can rotate forward and backward, which can make the storage battery supply power to the first motor 401 and the first pulley 402.

[0042] At the rear end of the inner wall of the bottom of the drive box 2 and the rear end of the inner wall of the top of the closed box 3, there are rectangular grooves that communicate with each other. The second belt 603 rotates in the rectangular groove. The top end of the first rotating rod 405 is rotatably connected to the inner wall of the top of the drive box 2, and the bottom end of the first lead screw 406 is rotatably connected to the inner wall of the bottom of the drive box 2. There are communicating lifting grooves in the middle of the bottom of the drive box 2, the middle of the top of the closed box 3, and the middle of the bottom of the closed box 3, which can expose the buffer box 509 from the bottom of the lifting groove.

[0043] The first lead screw 406 is provided with a first limiting ring near the top and the bottom, and the second lead screw 606 is provided with a second limiting ring near the left and right ends, which can limit the second ball screw pair 607 and the first ball screw pair 407.

[0044] A second guiding ring is fixedly connected to the front surface of the movable baffle 608, and the second guiding rod 609 is slidably connected to the center of the second guiding ring, which can guide the movable baffle 608.

[0045] The right end of the second lead screw 606 is rotatably connected to the right inner wall of the closed box 3. The number of the second lead screw 606, the second ball screw pair 607, and the movable baffle 608 is two, and the two second lead screws 606, the second ball screw pair 607, and the movable baffle 608 are symmetrically distributed on both sides of the second rotating rod 605, which can close the lifting groove.

[0046] By setting the first motor 401 and the second motor 601 as reversible motors, the buffer box 509 can be received inside the drive box 2 as needed, and at the same time, the lifting groove at the bottom of the closed box 3 can be controlled to be closed and opened, avoiding foreign objects entering the bottom of the closed box 3 during use.

[0047] When the autogyro 1 needs to land and be supported, turn on the first motor 401. When the first motor 401 is working, it drives the first pulley 402 to rotate. At this time, the first pulley 402 drives the second pulley 404 to rotate through the first belt 403, so that the first rotating rod 405 in the middle of the second pulley 404 rotates. At the same time, when the first rotating rod 405 rotates, it drives the first lead screw 406 to rotate, so that the first ball nut pair 407 moves up and down on the first lead screw 406, and at the same time, the connecting plate 408 moves up and down. Turn on the second motor 601. When the second motor 601 is working, it drives the third pulley 602 to rotate. The third pulley 602 drives the fourth belt 604 to rotate through the second belt 603, so that the second rotating rod 605 in the middle of the fourth belt 604 rotates. At the same time, the second rotating rod 605 drives the second lead screw 606 to rotate. At the same time, the second ball nut pair 607 moves on the second lead screw 606, so that the moving baffle 608 moves along with the second ball nut pair 607. The second guide ring on the moving baffle 608 moves on the guide rod 609, making the movement of the moving baffle 608 more stable. At the same time, the moving baffle 608 moves away from the lifting groove, so that the buffer box 509 can be removed from the lifting groove, and the buffer wheel 508 contacts the ground. When the buffer wheel 508 contacts the ground, the first spring 502 in the buffer box 509 is compressed, so that the damping wheel on the first spring 502 slides on the rubber plate on the inner wall of the buffer box 509. By setting the rubber plate, the force during falling can be buffered. Subsequently, when the connecting plate 408 moves down, it moves downward through the fixing block, so that the connecting rod 507 pushes the moving block 506 to move. The rubber wheel on the moving block 506 slides on the inner wall of the buffer groove 504, which can increase the resistance. At the same time, the second spring 505 is stretched. When the second spring 505 elastically recovers, the connecting plate 408 moves up, so that the connecting plate 408 drives the fixing plate to move up. At this time, the connecting rod 507 drives the moving block 506 to move, squeezing the second spring 505. At the same time, the material of the second spring 505 itself has a stretching function, and it holds the moving block 506 when the moving block 506 moves. At this time, a damping effect is generated, and the vibration when contacting the ground during falling can be reduced, and the autogyro 1 can be prevented from being damaged due to vibration.
