In specialized areas, such as flapers, landing gear, folding wings, and tiltrotors, simple cables are insufficient for motion. Therefore, products with the necessary functionality are needed to achieve both motion and optical and electrical connectivity. Existing products typically utilize helical cables, motion guides, and other methods. However, these products are unable to meet the requirements for large angles, deflection axes, and long travels, necessitating the invention of a new motion system to achieve these requirements.

[0070] like Figures 1A to 1C and Figure 2 、 Figure 3 、 Figure 4 、 Figure 12 、 Figure 13 、 Figure 15A 、 Figure 15B 、 Figure 16A 、 Figure 16B 、 Figure 17As shown, the gear transmission assembly of this embodiment includes a compound gear 15, a transmission rod 18 and a bevel gear 16. One end of the transmission rod 18 is installed in the bushing A102 on the side wall plate A101, and the other end of the transmission rod 18 is installed in the bushing C202 on the side wall plate B201, thereby realizing the rotation of the transmission rod 18 relative to the side wall plate A101 and the side wall plate B201; the compound gear 15 is connected to one end of the transmission rod 18 through a flat key pin A13, and the bevel gear 16 is connected to the other end of the transmission rod 18 through a flat key pin B14. The compound gear 15 and the bevel gear 16 are both linked to the transmission rod 18 and lock the axial movement trend, thereby realizing the synchronous movement of the compound gear 15 and the bevel gear 16, and converting the linear motion of the transmission spur rack 103 into rotational motion. In this embodiment, keyways C1801 are formed at both ends of the transmission rod 18 to accommodate flat key pins A13 and B14. Stepped sections are also provided at both ends of the transmission rod 18 to maintain the correct position of the compound gear 15 and bevel gear 16. On one side of the compound gear 15 in this embodiment, spur teeth 1501 mesh with the spur rack 103 for transmission, while on the other side, bevel teeth 1502 mesh with the bevel gear head at the bottom of the gear head worm gear A11 for transmission. The bevel teeth cooperate with the gear head worm gear A11 to change the motion angle and transmit motion. The number of spur teeth 1501 and bevel teeth 1502 is arranged according to a gear ratio of 1:6, while the number of bevel teeth 1502 and the bevel gear head of the gear head worm gear A11 is arranged according to a gear ratio of 3:1. The screw pitch of the gear head worm gear A11 is 3.5 mm. This arrangement amplifies the motion stroke of the isolation transmission member 8 compared to the push rod assembly 5, thereby achieving the required motion margin. Composite gear 15 has a keyway A1503 that mates with flat key pin A13 to lock transmission rod 18. Bevel gear 16 meshes with the bevel gear head at the bottom of worm gear B12, altering the angle of motion and transmitting the movement. Bevel gear 16 also has a keyway B1601 that mates with flat key pin B14 to lock transmission rod 18. The number of teeth on bevel gear 16 matches the number of teeth on bevel gear 1502 on the other side of composite gear 15, ensuring synchronized motion.

[0071] The working principle of the present invention is:

[0072] like Figure 18As shown, the bottom plate 3 is fixed to a fixed portion 25 on the aircraft, and the other ends of each bundle of moving cable assemblies 4 are respectively connected to the moving portion 24 on the aircraft. When the moving portion 24 moves, the push rod assembly 5 drives the transmission spur rack 103 to slide back and forth under the action of the movement of the moving portion 24. The meshing transmission between the transmission spur rack 103 and the spur teeth 1501 in the compound gear 15, the meshing transmission between the bevel teeth 1502 in the compound gear 15 and the bevel teeth of the tooth head worm gear A11, and the meshing transmission between the bevel gear 16 and the bevel teeth of the tooth head worm gear B12 convert the linear motion of the transmission spur rack 103 into the rotational motion of the tooth head worm gear A11 and the tooth head worm gear B12. The isolation transmission member 8 is raised and lowered by the helical pairs between the tooth head worm gear A11 and the tooth head worm gear B12, respectively. During the movement of the moving portion 24, each bundle of moving cable assemblies 4 provides the required motion margin and is limited by the lifting and lowering of the isolation transmission member 8.
