Technical Field

[0001] This utility model belongs to the field of rotorcraft technology and relates to a control mechanism for an autogyro. Background Technology

[0002] A gyroplane is a rotorcraft that uses the relative airflow during forward flight to drive the rotor to rotate and generate lift. This design ensures that the gyroplane will not stall or spin during flight, making it very safe.

[0003] For example, patent (CN212530052U) discloses a flight attitude control mechanism for an autogyro, which describes "including a control stick, connecting plate, pedal, control fork, control torque shaft, rudder reversing device, push rod swing arm, control rod, front wheel fork, tail rudder, seesaw, rotating plate, rotor frame, front wheel, and push rod structure. The pedal drives the first push rod, which drives the front wheel fork to achieve left and right steering of the front wheel; the pedal drives the second push rod, which drives the third push rod through the reversing device, and then the third push rod achieves the steering of the tail rudder; the control stick is used for forward, backward, left, and right control, and the torque rod interacts with the fourth push rod to transmit the direction of force to the control fork, and the push rod first transmits the force to the push rod swing arm, and finally to the control rod, ultimately achieving the up, down, left, and right swing of the rotating plate. This utility model patent has a reasonable structural design, simple structure, and is easy to assemble, which can achieve accurate control of flight attitude and has good maneuverability and adaptability."

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing autogyro usually adjusts the angle of the wing manually. The autogyro is very sensitive to changes in the rotor tilt angle, which is quite inconvenient to operate and there are many difficulties in manual adjustment. Therefore, based on the above technical problems, an autogyro control mechanism is proposed. Utility Model Content

[0005] The technical problem this invention aims to solve is that autogyros typically adjust the wing angle manually. Autogyros are very sensitive to changes in rotor tilt angle, making them quite inconvenient to operate and difficult to adjust manually.

[0006] The present invention discloses a control mechanism for an autogyro, comprising a column, a connecting seat fixedly connected to the top of the column, an adjusting seat fixedly connected to the bottom of the connecting seat, a fixing plate fixedly connected to the inner side of the adjusting seat, a servo motor fixedly connected to one end of the fixing plate, a transmission column rotatably connected to the end of the fixing plate away from the servo motor, and the output end of the servo motor fixedly connected to the transmission column.

[0009] The automatic adjustment assembly further includes a first adjustment frame, an adjustment rod, and a mounting screw. The first adjustment frame is fixedly connected to the end of the rotating column away from the fixed plate. The adjustment rod is detachably connected to the side of the first adjustment frame away from the rotating column. The mounting screw is threadedly connected to the end of the first adjustment frame away from the rotating column.

[0010] The inner side of the connecting seat is rotatably connected to the mounting seat via a rotating shaft, the top of the mounting seat is rotatably connected to the rotating seat via a rotating shaft, and the top of the rotating seat is fixedly connected to the self-rotating seat.

[0026] Example 1

[0027] like Figures 1-5 As shown, a control mechanism for an autogyro includes a column 1. To facilitate the installation of the autogyro wing, a connecting seat 2 is fixedly connected to the top of the column 1. To facilitate the adjustment of the angle of the autogyro wing, an adjusting seat 3 is fixedly connected to the bottom of the connecting seat 2. A fixing plate 4 is fixedly connected to the inner side of the adjusting seat 3. A servo motor 5 is fixedly connected to one end of the fixing plate 4. A transmission column 6 is rotatably connected to the end of the fixing plate 4 away from the servo motor 5. To facilitate the rotation of the transmission column 6 by the servo motor 5, the output end of the servo motor 5 is fixedly connected to the transmission column 6.

[0028] The automatic adjustment component is located inside the adjustment seat 3. The servo motor 5 is used in conjunction with the automatic adjustment component. The servo motor 5 drives the automatic adjustment component through the transmission column 6 to tilt the wing forward or backward, so that the gyroplane pilot can quickly and accurately adjust the wing, reduce the difficulty of adjusting the wing, improve the flight safety of the gyroplane pilot, and further improve the effectiveness of the device.

[0029] The automatic adjustment assembly includes a first transmission gear 7, a rotating column 8, a connecting frame 9, a second transmission gear 10, a fixed column 23, and a third transmission gear 24. The first transmission gear 7 is fixedly connected to the ring side of the transmission column 6. Rotating columns 8 are rotatably connected to both sides of the adjustment seat 3 away from the servo motor 5. A connecting frame 9 is rotatably connected to the end of the rotating column 8 near the fixed plate 4. The end of the connecting frame 9 away from the servo motor 5 is fixedly connected to the adjustment seat 3. The second transmission gear 10 is fixedly connected to the end of the rotating column 8 near the servo motor 5. To facilitate the rotation of the corresponding second transmission gear 10 via the first transmission gear 7, the second transmission gear 24 is located on one side of the fixed plate 4. The transmission gear 10 is meshed with the first transmission gear 7. A fixed column 23 is rotatably connected to the bottom end of the fixed plate 4 at a position corresponding to the transmission column 6. A third transmission gear 24 is fixedly connected to the ring side of the fixed column 23. In order to facilitate the rotation of the third transmission gear 24 by the first transmission gear 7, the third transmission gear 24 is meshed with the first transmission gear 7. In order to facilitate the rotation of the second transmission gear 10 corresponding to it by the third transmission gear 24, the second transmission gear 10 located on the other side of the fixed plate 4 is meshed with the third transmission gear 24, thereby facilitating the rotation of the two second transmission gears 10 in opposite directions by the first transmission gear 7.

[0030] The automatic adjustment assembly also includes a first adjustment frame 11, an adjustment rod 12, and a mounting screw 13. The first adjustment frame 11 is fixedly connected to the end of the rotating column 8 away from the fixed plate 4. The adjustment rod 12 is detachably connected to the side of the first adjustment frame 11 away from the rotating column 8. The mounting screw 13 is threadedly connected to the end of the first adjustment frame 11 away from the rotating column 8, thereby facilitating the movement of the adjustment rod 12 by the first adjustment frame 11.

[0031] During operation, when it is necessary to drive the two first adjustment frames 11 to rotate downwards or upwards simultaneously, the servo motor 5 is started, and the output end of the servo motor 5 drives the transmission column 6 and the first transmission gear 7 to rotate. The first transmission gear 7 then drives the corresponding second transmission gear 10 to rotate, which in turn drives the third transmission gear 24 to rotate. The third transmission gear 24 then drives the corresponding second transmission gear 10 to rotate. When the first transmission gear 7 moves clockwise, it drives the corresponding second transmission gear 10 to move counterclockwise. At the same time, the first transmission gear 7 drives the third transmission gear 24 to move counterclockwise, which in turn drives the corresponding second transmission gear 10 to move clockwise. Thus, the two second transmission gears 10 drive the first adjustment frames 11 to rotate in opposite directions through the rotating column 8, resulting in the two first adjustment frames 11 rotating downwards or upwards simultaneously.

[0032] Example 2

[0033] like Figure 1 and Figure 2 The inner side of the connecting seat 2 is rotatably connected to the mounting seat 14 via a rotating shaft. The top of the mounting seat 14 is rotatably connected to the rotating seat 15 via a rotating shaft, which facilitates the adjustment of the angle of the rotating seat 15 on the connecting seat 2 via the mounting seat 14. The top of the rotating seat 15 is fixedly connected to the self-rotating seat 16.

[0034] To facilitate the adjustment of the angles of the rotating seat 15 and the self-rotating seat 16, a fixed frame 17 is fixedly connected to one side of the top of the rotating seat 15. A C-shaped frame 18 is fixedly connected to the end of the fixed frame 17 away from the rotating seat 15. A drive shaft 19 is fixedly connected to both sides of the inner side of the C-shaped frame 18. A second adjustment frame 20 is rotatably connected to the ring side of the drive shaft 19. The bottom end of the second adjustment frame 20 is fixedly connected to the adjustment rod 12, thereby facilitating the adjustment of the wing's operating angle by driving the adjustment rod 12 through the first adjustment frame 11.

[0035] The top of the self-rotating seat 16 is rotatably connected to the wing seat 21, and the inner side of the wing seat 21 is detachably connected to the mounting bracket 22, which facilitates the installation and removal of the wing through the mounting bracket 22.

[0036] During operation, when the first adjusting frame 11 moves the adjusting rod 12 upward or downward, it drives the self-rotating seat 16 and the wing connected to it to move through the C-shaped frame 18. When the adjusting rod 12 moves upward, it drives the wing to tilt forward around the rotation axis of the rotating seat 15 through the self-rotating seat 16. When the adjusting rod 12 moves downward, it drives the wing to tilt backward around the rotation axis of the rotating seat 15 through the self-rotating seat 16. This facilitates the automatic adjustment of the wing's operating angle through the adjusting rod 12.
