[0002] A tilt-wing is a type of rotatable wing. Depending on the rotation mode, the aircraft has different flight characteristics. When the tilt-wing is in a vertical position, the aircraft can hover, fly sideways, fly backwards, take off and land vertically, etc. However, when the existing rotor tilt mechanism rotates for a long time, the tilt angle is difficult to control due to the different wind speeds encountered, which can easily cause the fuselage to become unstable.

[0008] As a preferred technical solution of the present utility model, there are four fixed blocks, which are respectively located on the left and right sides of the fixed ring; there are two connecting shafts, which are respectively located inside the four fixed blocks; there are two rotating sleeves and two fixed sleeves, which are respectively rotatably connected to the two connecting shafts.

[0009] As a preferred technical solution of the present invention, the end of the rotating shaft away from the ball sleeve is fixedly connected to the fuselage, so that the direction and position of the rotating shaft are fixed. There are two wings, and both wings are located above the connecting shell.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a dual self-locking rotor tilt mechanism, including a connecting shell 1, a motor 2 is fixedly installed on the bottom of the connecting shell 1, a driving gear 3 is fixedly installed on the output end of the motor 2, a rotating shaft 4 is rotatably connected to the inside of the connecting shell 1, a driven gear 5 is fixedly installed on the outside of the rotating shaft 4, the driving gear 3 and the driven gear 5 are in meshing shape, a fixing ring 6 is fixedly installed on the outside of the rotating shaft 4, and a fixing block 7 is fixedly installed on the outside of the fixing ring 6.

[0021] The starting motor 2 drives the driving gear 3 to rotate through the output end, so that the driving gear 3 is engaged with the driven gear 5, thereby driving the rotating shaft 4 to rotate rapidly, achieving the effect of driving the fuselage to rise and fall through high-speed rotation.

[0022] Among them, the interior of the fixed block 7 is plugged with a connecting shaft 8, the outer side of the connecting shaft 8 is sleeved with a rotating sleeve 9, a fixed sleeve 10 is fixedly installed above the rotating sleeve 9, a limiting plate 11 is fixedly installed on the outer side of the fixed sleeve 10, a spring 12 is sleeved on the outer side of the fixed sleeve 10, and the interior of the fixed sleeve 10 is slidably connected to a connecting rod 13.

[0023] The spring 12 is located on the outside of the connecting rod 13. When the wing 18 tilts, the connecting rod 13 is pressed down, causing the connecting rod 13 to contract inside the spring 12, thereby achieving the effect of tilting while maintaining the stability of the wing 18.

[0024] Among them, a ball sleeve 14 is fixedly installed above the rotating shaft 4, and a universal ball 15 is provided inside the ball sleeve 14. The outer side of the universal ball 15 is sleeved with a limit sleeve 16. The limit sleeve 16 is located above the ball sleeve 14, and the limit sleeve 16 and the ball sleeve 14 are connected by bolts.

[0025] The inner diameter of the ball sleeve 14 is smaller than the diameter at the center of the universal ball 15. When the universal ball 15 rotates inside the ball sleeve 14, the surrounding area will be limited by the limiting sleeve 16, thereby ensuring the overall stability of the universal ball 15 while ensuring the rotation of the universal ball 15.

[0026] Among them, a connecting block 17 is fixedly installed above the universal ball 15, and a wing 18 and a connecting component 19 are fixedly installed on the outside of the connecting block 17. A slide groove 20 is opened inside the connecting component 19, and a slider 21 is slidably connected inside the slide groove 20. A limit plate 22 is fixedly installed at the bottom of the slider 21, and a fixed sleeve 23 is fixedly installed at the bottom of the limit plate 22.

[0027] The limiting plate 22 is located above the spring 12, and the fixing sleeve 23 is located inside the connecting rod 13 and inside the spring 12. At the same time, the fixing sleeve 23 is located above the fixing sleeve 10. The main function of the limiting plate 22 is to limit the spring 12 to prevent the spring 12 from providing more force under the action of elastic force, causing the connecting component 19 to tilt upward.

[0028] Among them, there are four fixed blocks 7, which are respectively located on the left and right sides of the fixed ring 6; there are two connecting shafts 8, which are respectively located inside the four fixed blocks 7; there are two rotating sleeves 9 and two fixed sleeves 10, and the two rotating sleeves 9 are respectively connected to the two connecting shafts 8 for rotation.

[0029] When the wing 18 needs to adjust its direction and tilt according to the airflow, the connecting component 19 will be pressed downward, so that the slider 21 will slide inside the slide groove 20, causing the spring 12, the connecting rod 13 and the fixing sleeve 23 to tilt outward, thereby achieving a certain supporting effect on the connecting component 19. At the same time, when the wing 18 does not need to move, the spring 12 provides elastic force to reset the connecting component 19 and keep it parallel to the wing 18.

[0030] Among them, one end of the rotating shaft 4 away from the ball sleeve 14 is fixedly connected to the fuselage, so that the direction and position of the rotating shaft 4 are fixed. There are two wings 18, and the two wings 18 are both located above the connecting shell 1.

[0031] The main function of the two wings 18 is to generate an upward force by rotating at high speed, so that the fuselage can be lifted up easily, and at the same time, to realize forward and backward instructions by adjusting the tilt angle.

[0032] The working principle and use process of this utility model:

[0033] First, the motor 2 is started to drive the driving gear 3 to rotate through the output end, so that the driving gear 3 is engaged with the driven gear 5, thereby driving the rotating shaft 4 to rotate at high speed;

[0034] At the same time, since a fixing ring 6 is fixedly installed on the outside of the rotating shaft 4, a fixing block 7 is fixedly installed on the outside of the fixing ring 6, a connecting shaft 8 is inserted into the inside of the fixing block 7, a rotating sleeve 9 is sleeved on the outside of the connecting shaft 8, a fixing sleeve 10 and a limiting plate 11 are fixedly installed above the rotating sleeve 9, and a spring 12 is fixedly sleeved on the outside of the fixing sleeve 10 and the limiting plate 11, and a slider 21 is fixedly installed above the spring 12. The slider 21 is located inside the connecting assembly 19. Therefore, when the rotating shaft 4 rotates, it will drive the connecting assembly 19 to rotate at high speed, and at the same time, the wing 18 will rotate, so as to achieve the effect of driving the fuselage to rise, move forward and backward, and land;

[0035] Finally, when the inclination angle of the wing 18 needs to be adjusted, the universal ball 15 will rotate in the limit sleeve 16, so that the angle of the connecting block 17 is tilted, thereby adjusting the inclination of the wing 18. At the same time, since the universal ball 15 is spherical, the friction generated by the rotation inside the limit sleeve 16 is small, so the temperature generated is small, which improves the overall service life.
